Description
Technical Field
The invention relates to the technical field of wine brewing, in particular to a wine brewing distillation system with a liquid level measuring device and a liquid level measuring method.
Background
The liquid level of the liquor retort bottom pot plays a crucial role in the liquor distillation process, and the selection of the measurement mode and the measurement device is a decisive factor for ensuring the accuracy of the liquid level measurement of the liquor retort bottom pot.
At present, when the liquid level of a liquor retort bottom pot is measured, a pressure taking port is usually installed at the bottom of the liquor retort bottom pot, but in the liquor distillation process, part of fermented grains fall into bottom water and enter a pressure guide pipe through a pressure measuring and taking hole at the bottom of the bottom pot, so that the pressure guide pipe is blocked, and the smooth measurement of the liquid level of the liquor retort bottom pot is influenced.
Although the liquid level measurement can be recovered after the fermented grains accumulated in the pressure guide pipe are cleaned, frequent blockage for a long time brings huge invalid workload for equipment maintenance, and also brings certain influence on continuous and stable operation of wine brewing production, so that not only is the efficiency of wine brewing production influenced, but also frequent interruption and restarting of the white spirit brewing process are inevitably caused in the frequent blockage and maintenance process, and whether the frequent interruption and restarting of the white spirit brewing process causes unexpected material change caused by time and space lapse or not is difficult to effectively estimate the influence on the quality and flavor of the white spirit, so that the continuity of the white spirit brewing process is ensured to be particularly important. Accordingly, there is still a need in the art to solve at least one or more of the above problems, and the present invention is directed to a liquid level measuring device.
Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the applicant has studied a great deal of literature and patents when making the present invention, but the disclosure is not limited thereto and the details and contents thereof are not listed in detail, it is by no means the present invention has these prior art features, but the present invention has all the features of the prior art, and the applicant reserves the right to increase the related prior art in the background.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a brewing distillation system with a liquid level measuring device and a liquid level measuring method, aiming at solving at least one or more technical problems in the prior art.
In order to achieve the above object, the present invention provides a wine distillation system with a liquid level measuring device, at least comprising:
the wine retort bottom pot is used for distilling fermented grains, and the bottom of the wine retort bottom pot is provided with a pressure sampling hole;
liquid level measurement device, it connects in wine rice steamer end pot through the pressure thief hole for measure the inside mixed solution liquid level that contains the fermented grain granule of wine rice steamer end pot, wherein, liquid level measurement device includes:
the filter element is connected above the pressure sampling hole in a manner of being partially embedded in the pressure sampling hole, and is used for physically blocking fermented grains in the immersed mixed solution from flowing into the pressure sampling hole;
a combined conduit, a part of which passes through the pressure sampling hole and is communicated with the filter element, so as to at least accumulate the mixed solution which flows out through the filter element and filters the grains;
the micro-differential pressure transmitter is arranged inside the combined conduit and is used for providing a liquid level value aiming at the mixed solution inside the wine retort bottom pot; wherein the content of the first and second substances,
the filter element is provided with a plurality of filter holes which are distributed along the circumferential direction of the filter element along the vertical and/or transverse gaps and penetrate through the filter element in the radial direction and extend to the liquid flow channel in the filter element. Because the bottom water of the wine retort bottom boiler contains a large amount of fermented grains which can enter the pressure guide pipe based on the flowing of water body to cause the blockage of the pressure guide pipe and influence the accuracy of the liquid level measurement result of the wine retort bottom boiler, in the invention, the filtering element with the filtering hole is arranged above the pressure sampling hole, and the filtering element can filter the fermented grains in the bottom water out of the filtering element, thereby preventing the fermented grains from flowing into the pressure guide pipe, and the water body in the wine retort bottom boiler can be periodically discharged through the combined guide pipe, so that fine grains which can possibly enter the combined guide pipe are cleaned and discharged, and the influence of the fermented grains on the liquid level measurement result of the wine retort bottom boiler is reduced.
Preferably, the size of the filtering holes circumferentially arranged by the filtering elements is gradually reduced in the vertical upward direction, wherein the mixed solution forms settled layers and floating layers containing fermented grains with different grain sizes in the bottom pot of the wine retort based on the grain size difference of the contained fermented grains, so that the size of the filtering holes of the settled layers closer to the bottom of the mixed solution is larger than that of the floating layers closer to the top of the mixed solution. Considering the volume and/or weight distribution difference between the grains in the bottom water of the wine retort bottom pot and different liquid level surfaces, the size of the filtration pores on the peripheral side of the filtration element is gradually reduced from the bottom deposition layer of the mixed solution to the top floating layer thereof, therefore, when water at the bottom of the boiler containing fermented grains flows through the filtering holes, the filtering holes can block most of the fermented grains from entering the filtering element based on the size difference so as to prevent the fermented grains from accumulating to the pressure guide pipe to cause the blockage of the pressure guide pipe, even if the fermented grains in the settled layer at the bottom of the pot bottom water tend to flow upwards to the floating layer at the top of the pot bottom water due to the fluctuation of the liquid level, since the size of the filter holes in the top row of the filter element is smaller than that of the filter holes below the filter element, the fermented grains floating from the bottom layer are difficult to flow into the filter element from the upper part, and the possibility and the entering amount of the fermented grains in the water at the bottom of the boiler entering the pressure guide pipe 206 are further reduced.
Preferably, the filter openings are radially connected to the filter element interior flow passage and the filter openings have a decreasing extension in the direction of the filter element interior flow passage. In the invention, the filter hole is constructed in a tapered shape, even though grains flow inwards along the filter hole under the drive of water flow, the possibility of the grains entering the pressure guide pipe is further reduced because the outlet is gradually reduced, in addition, when the pipe cleaning work is required before the liquid level measurement, because the filter hole is provided with the outlet which is tapered towards the first liquid flow channel, when the water flow flows along the flow channel of the filter hole structure and flows out through the tapered outlet communicated with the first liquid flow channel, the tapered outlet enhances the kinetic energy or potential energy of the emergent water flow, and when the emergent water flow touches the inner wall of the pressure guide pipe in an oblique line or parabola mode, the kinetic energy or potential energy of the emergent water flow is enhanced because of the tapered outlet, so that the impact strength of the water flow on the inner wall of the pressure guide pipe is enhanced, and when the emergent water flow flows through the inner wall of the combined pipe, particularly the pressure guide pipe, the stripping or removing effect of the impurities attached to the inner wall of the conduit can be enhanced by means of increased kinetic energy or potential energy, so that the influence of the impurities attached to the inside of the conduit on the accuracy of a liquid level measurement result is reduced in the later liquid level measurement process.
Preferably, the combined conduit at least comprises a pressure guide pipe and a three-way pipe which are sequentially connected along the extending direction of the pressure sampling hole, wherein one end of the pressure guide pipe is connected to the filter element in a manner of being embedded into the sampling hole, and the other end of the pressure guide pipe is communicated with the three-way pipe.
Preferably, the tee is constituted by a first conduit and a second conduit communicating with each other, wherein,
the first guide pipe is axially communicated with the pressure guide pipe and extends along the flow direction of the pressure guide pipe;
the second conduit is in radial communication with the first conduit and extends in a direction away from the first conduit at an angle relative to the first conduit.
Preferably, a micro-differential pressure transmitter is disposed at a port of the second conduit remote from the first conduit, the micro-differential pressure transmitter providing a level value for the mixed solution when the mixed solution level within the combined conduit is higher than the micro-differential pressure transmitter.
Preferably, the combined conduit further comprises a settling tube communicating with the first conduit, and an end of the settling tube remote from the first conduit is provided with a discharge valve for controlling the outflow of the mixed solution.
Preferably, the invention provides a wine retort bottom pot liquid level measuring method based on the liquid level measuring device, which comprises the following steps:
adding water to the wine retort bottom pot to filter holes of the filtering element under the condition that the combined conduit is closed, and taking the readings carved by the micro-differential pressure transmitter at the same time as the liquid level zero value of the wine retort bottom pot;
when the liquid level of the mixed solution in the wine retort bottom pot changes to at least another liquid level surface different from the liquid level zero value, the readings of the micro-differential pressure transmitter at the same time are used as the real-time liquid level value of the wine retort bottom pot; wherein the content of the first and second substances,
the filter holes of the filter element are distributed along the circumferential direction of the filter element along the vertical direction and/or the transverse direction at intervals, penetrate through the filter element in the radial direction and extend to the liquid flow channel inside the filter element so as to physically block fermented grains in the immersed mixed solution from flowing into the combined conduit.
Preferably, before adding water to the liquor retort bottom pot to submerge the filtering holes of the filtering element to obtain a liquid level zero value, the method further comprises the following steps:
and adding water into the bottom pot of the wine retort under the condition that the combined conduit is opened to enable the water to flow out through the combined conduit, and adjusting the combined conduit to be in a closed state after fermented grains in the combined conduit are discharged through the flowing of the water.

Detailed Description
The following detailed description is made with reference to the accompanying drawings.
The invention provides a brewing distillation system with a liquid level measuring device, which can comprise one of the following components as shown in figure 1:
a wine retort bottom pot 10 for steaming and boiling the fermented grains;
and the liquid level measuring device 20 is arranged at the bottom of the wine retort bottom pot 10 and is connected to a pressure sampling hole formed in the bottom of the wine retort bottom pot 10 in an at least partially embedded mode so as to be used for measuring the real-time liquid level value of the wine retort bottom pot 10.
According to a preferred embodiment, as shown in fig. 1, the liquid level measuring device 20 of the present invention may comprise a filter element 201, a pressure pipe 206, a tee 203, a settling pipe 204 and a discharge valve 205, which are connected in sequence along the height direction of the wine retort bottom 10, and a micro-differential pressure transmitter 202 disposed at the vacant port of the tee 203.
Specifically, as shown in fig. 1, when the liquid level value of the wine retort bottom pot 10 is measured by the liquid level measuring device 20, the bottom water containing fermented grains flows into the filter element 201 at the top of the liquid level measuring device 20, and the filter element 201 can be used for preventing the fermented grains in the bottom water from entering the pressure guide pipe 206 through the pressure sampling hole at the bottom of the wine retort bottom pot 10 to cause the blockage of the pressure guide pipe 206, thereby affecting the normal operation of the liquid level measuring device 20 of the present invention.
According to a preferred embodiment, as shown in fig. 1, the filter element 201 is at least partially located above the pressure sampling hole with reference to the pressure sampling hole at the bottom of the wine retort bottom 10, and is specifically accommodated in the space in the inner cavity of the wine retort bottom 10 and close to the pressure sampling hole, so that part of it can be immersed in the bottom water of the wine retort bottom 10. On the other hand, at least another portion of the bottom of the filter element 201 is fitted into the pressure sampling hole and connected to the pressure pipe 206.
According to a preferred embodiment, as shown in fig. 1, a pressure pipe 206 disposed at the bottom of the filter element 201 is in fluid communication with the filter element 201 in such a manner as to be at least partially fitted to the pressure sampling hole, for receiving bottom water for removing fermented grains. Preferably, in the present invention, the pressure pipe 206 may be made of stainless steel.
According to a preferred embodiment, as shown in fig. 2, a schematic cross-sectional configuration of a filter element 201 of the present invention is shown. Specifically, the filter element 201 is composed of a filter portion 21 and a clamping portion 22 which are sequentially connected from top to bottom along the height direction of the wine retort bottom pot 10. Preferably, in the present invention, the filter element 201 as a whole may be made of stainless steel. Particularly, since the filter element 201 is made of stainless steel, it has high structural strength, and even if it is soaked in the bottom water of a pot for a long time, it will not generate physical or chemical changes due to contact with the bottom water and/or fermented grains in the bottom water, thereby causing deformation failure of itself, and generating unexpected changes to affect the accuracy of liquid level measurement, even affect the quality of fermented grain distillation.
According to a preferred embodiment, as shown in fig. 2, the filter part 21 is a substantially discoid table structure made of a stainless steel blind plate. Further, the outer diameter of the filtering portion 21 is larger than the diameter of the pressure sampling hole and/or the pressure guiding pipe 206 at the bottom of the wine retort bottom pan 10. For example, in some alternatives, the pressure pipe 206 is a stainless steel pipe DN20mm, and the filter portion 21 is composed of a stainless steel blind plate with a diameter of 51mm × 2.
According to a preferred embodiment, as shown in fig. 2, the filter portion 21 has a plurality of filter holes 210 arranged on the outer side in the circumferential direction thereof. Specifically, the filtering holes 210 are configured to penetrate and extend to the middle of the filtering portion 21 in the radial direction, and the filtering holes 210 physically block fermented grains in the bottom water from entering the filtering portion 21, and the pressure guide pipe 206 is left in the wine retort bottom pot 10, thereby preventing the pressure guide pipe 206 from being blocked due to the accumulation of the fermented grains.
In particular, the size of the filtering holes 210 should be set according to the size of the particle diameter of the foreign particles to be filtered, and preferably should be smaller than the size of the particle diameter of the foreign particles. In addition, the liquid level measuring device 20 of the present invention can be used to measure the liquid level of other liquids containing different impurities, and the size of the filtering holes 210 can be adjusted according to the physical size of different impurity particles.
According to a preferred embodiment, since the shapes of the bran shell materials are not all regularly or uniformly distributed, the volume and weight of the fermented grains falling into the bottom water during the distillation of the fermented grains are also uneven. Further, when fermented grains having different volumes and/or weights fall into the bottom water, the probability that the fermented grains having larger volumes and/or weights are deposited to the bottom of the distiller's bottom pot 10 increases and gradually converges in the water layer near the bottom water to form a deposited layer, and the fermented grains having smaller volumes and/or weights are more likely to be free or float to the surface layer of the bottom water because they are more flocculent or punctiform fine grains, which converge in the water layer near the surface layer of the bottom water to form a floating layer, whereby when the sizes of the fermented grains in the bottom water are not the same, the bottom water containing the fermented grains enters the filtering holes 210 of the filtering element 201, and the filtering holes 210 also have different filtering effects on the fermented grains having different shapes in different water layers.
In particular, the volume and/or weight of the fermented grains in the bottom water deposition layer are generally relatively large, while the volume and/or weight of the fermented grains in the bottom water floating layer are relatively small, that is, the volume and/or weight of the fermented grains distributed in the bottom water tends to gradually decrease in the vertical direction of the bottom water, so that the sizes of the plurality of filter holes 210 distributed in the circumferential outer side of the filter portion 21 of the filter element 201 are preferably different with respect to the difference in the volume and/or weight of the fermented grains in different water layers, and the sizes of the filter holes 210 distributed in different transverse rows are different at least in the vertical direction of the filter portion 21.
According to a preferred embodiment, in the present invention, in order to improve the filtering efficiency and effect of the filtering element 201 on the fermented grains in the water layers at different liquid levels in the bottom water of the boiler, considering the distribution difference of the volume and/or weight of the fermented grains in the bottom water of the boiler in the vertical direction, the filtering holes 210 distributed on the circumferential outer side of the filtering part 21 of the filtering element 201 are arranged in a manner that the sizes of the plurality of horizontal filtering holes 210 arranged along the vertical gap gradually decrease linearly or nonlinearly from the bottom water of the boiler to the top floating layer thereof, that is, the sizes of the plurality of filtering holes 210 distributed horizontally closer to the bottom of the filtering part 21 are larger than the sizes of the plurality of filtering holes 210 distributed horizontally farther from the bottom of the filtering part 21. In some alternative embodiments, for example, when only three rows of filtering holes 210 are circumferentially distributed on the filtering portion 21, the filtering holes 210 distributed in the bottom horizontal row of the filtering portion 21 are round holes with a diameter of 2.5mm, the filtering holes 210 distributed in the middle horizontal row of the filtering portion 21 are round holes with a diameter of 2mm, and the filtering holes 210 distributed in the top horizontal row of the filtering portion 21 are round holes with a diameter of 1.5 mm.
According to a preferred embodiment, when the bottom water containing fermented grains flows in through the filtering holes 210 of the filtering part 21 in a distribution state that the sizes of the plurality of rows of filtering holes 210 circumferentially arranged in the filtering part 21 are not completely the same and preferably gradually decrease toward the top floating layer along the bottom deposited layer of the bottom water, the flow of the bottom water may drive the fermented grains to move toward the filtering holes 210, since the designed size of the filtering holes 210 is smaller than the size of the fermented grains, the filtering holes 210 can block most of the fermented grains from entering into the filtering part 21 to prevent the fermented grains from accumulating to the pressure guiding pipe 206 to cause blockage thereof, and particularly for the plurality of filtering holes 210 arranged in the horizontal rows at the bottom of the filtering part 21, the designed size of the filtering holes 210 corresponding to the bottom deposited layer area of the bottom water is appropriately enlarged in consideration of the volume and/or weight characteristics of the fermented grains in the bottom deposited layer of the bottom water, the grain size of the grains in the bottom water sediment layer is larger than that of the bottom water sediment layer so as to prevent the grains from entering the pressure guide pipe 206, and meanwhile, when the pressure guide pipe 206, the three-way pipe 203 and the settling pipe 204 at the bottom of the wine retort bottom pot 10 are required to be washed and cleaned before the liquid level is measured, when the bottom water enters the pressure guide pipe 206 from a plurality of filtering holes 210 which are transversely arranged at the bottom of the filtering part 21 and have larger sizes, in unit time, the filtering holes 210 with relatively large calibers can enable a larger amount of bottom water to flow into the pressure guide pipe 206, so that the removing effect of impurities in the pipe, particularly sticky substances attached to the pipe wall, is improved.
On the other hand, when the fermented grains in the bottom settled layer tend to flow upward to the floating layer on the top of the bottom water due to the fluctuation of the liquid level, since the size of the filter holes 210 in the horizontal row at the top of the filtering part 21 is smaller than the size of the filter holes 210 below the same, even if the fermented grains floating from the bottom layer tend to enter the pressure guiding pipe 206 through the filter holes 210 in the horizontal row at the top of the filtering part 21, the possibility of the fermented grains in the bottom water entering the pressure guiding pipe 206 is further reduced because the size difference between the fermented grains in the bottom settled layer of the bottom water and the filter holes 210 in the horizontal row at the top of the filtering part 21, particularly, the size of the filter holes 210 in the horizontal row at the top of the filtering part 21 is smaller than the size of the filter holes 210 in the horizontal row at the bottom.
In particular, as a more preferred embodiment, in the present invention, the sizes of the plurality of rows of filtering holes 210 circumferentially arranged in the filtering portion 21 are designed according to the volume and/or weight difference of the fermented grains in the water layer at different liquid levels in the bottom water of the pan, so as to avoid the fermented grains in the bottom water of the pan from having a tendency to enter the pressure guiding pipe 206 from the filtering holes 210 corresponding to different liquid level surfaces when the sizes of all the filtering holes 210 are the same.
According to a preferred embodiment, as shown in fig. 2, several filter holes 210 are arranged with a vertical and a horizontal clearance along the filter portion 21, respectively, and adjacent filter holes 210 distributed along the vertical and horizontal directions of the filter portion 21 each have a filter hole clearance 300 with respect to each other. In some alternatives, the filter aperture gap 300 is, for example, 6 mm. Further, the filtering holes 210 close to both top and bottom sides of the filtering portion 21 and distributed along the transverse gap have an excessive gap with respect to the respective side surface. In some alternatives, the filter holes 210 disposed near both vertical ends of the filter portion 21 have a surplus gap of about 3mm from the top or bottom surface of the filter portion 21.
According to a preferred embodiment, a plurality of filter holes 210 distributed at intervals on the circumferential outer side of the filter portion 21 radially penetrate and extend to a first liquid flow channel (not shown) which is communicated with the middle part of the filter portion 21 and has one end inside the filter portion 21. In some alternatives, the first flow channel is, for example, a 32mm cylindrical channel.
According to a preferred embodiment, in order to further improve the filtering effect of the filter portion 21 of the filter element 201 on the fermented grains, the filter holes 210 on the circumferential outer side of the filter portion 21 may be configured as: the inner diameter of which decreases in the direction extending towards the first flow channel, in other words the filter openings 210 have a conical-like shape with a gradually decreasing outlet in the transverse direction with respect to the first flow channel.
Preferably, when the filtering holes 210 are configured in a "tapered" manner, even if the fermented grains are driven by the water flow to flow in along the filtering holes 210, the outlet is gradually reduced, so that the possibility of the fermented grains entering the pressure guide pipe 206 is further reduced, besides, when the conduit cleaning operation is required before the liquid level measurement, because the filtering holes 210 have the outlets tapered toward the first liquid flow channel, when the water flow flows along the flow channel configured by the filtering holes 210 and flows out through the "tapered" outlet communicated with the first liquid flow channel, the kinetic energy or potential energy of the outgoing water flow is enhanced by the "tapered" outlet, and when the outgoing water flow touches the inner wall of the pressure guide pipe 206 and the opposite clamping portion 22 in a slanted line or a parabolic line, the outgoing water flow enhances the flowing kinetic energy or potential energy due to the "tapered" outlet, so that the impact strength of the outgoing water flow on the inner wall of the pressure guide pipe 206 is enhanced, therefore, when the emergent water flow flows through the inner wall of the conduit, especially the inner wall of the pressure guide pipe 206, the stripping or removing effect of the impurities attached to the inner wall of the conduit can be enhanced by means of the increased kinetic energy or potential energy, so that the influence of the impurities attached to the inner part of the conduit on the accuracy of the liquid level measurement result is reduced in the later liquid level measurement process.
In some alternative embodiments, for example, when only three rows of filtering holes 210 are circumferentially distributed on the filtering portion 21, taking the filtering hole 210 distributed at the bottom layer of the filtering portion 21 as an example, the inlet of the filtering hole 210 distributed at the bottom transverse row of the filtering portion 21 may be a round hole with a diameter of 2.5mm, and the outlet thereof communicated with the first liquid flow channel may be a round hole with a diameter of 2 mm.
According to a preferred embodiment, the first flow channel extends along the axial direction of the filter portion 21 at two ends, and one end of the first flow channel extends and communicates with the clamping portion 22 at the bottom of the filter portion 21, and the other end of the first flow channel extends towards the top of the filter portion 21 but does not penetrate through the top surface of the filter portion 21. In particular, the end of the first flow channel extending towards the top of the filter house 21 preferably communicates with the radially inward end of the filter holes 210 distributed near the top of the filter house 21.
According to a preferred embodiment, as shown in fig. 2, the clamping portion 22 connected to the bottom of the filter portion 21 is a hollow tubular structure having a substantially cylindrical shape. Specifically, the outer side surface of the cylindrical clamping portion 22 in the circumferential direction of the portion away from the side of the filtering portion 21 has an external thread structure, and the clamping portion 22 can be connected and fixed in the pressure sampling hole at the bottom of the wine retort bottom pot 10 through the external thread structure, so as to fix the filtering portion 21 arranged at the top of the clamping portion above the pressure sampling hole. Further, a second fluid passage is disposed in the middle of the clamping portion 22, and the second fluid passage is axially communicated with the first fluid passage in the middle of the filtering portion 21.
According to a preferred embodiment, when the bottom water in the wine retort bottom pot 10 flows to and flows out of the pressure sampling hole through the filtering element 201 which is immersed in the bottom water and consists of the filtering portion 21 and the clamping portion 22, the bottom water flows into the first flow channel inside the filtering portion 21 through the plurality of filtering holes 210 distributed on the circumferential outer side surface of the filtering portion 21, and most of fermented grains in the bottom water are isolated and filtered by the filtering holes 210 on the circumferential outer side surface of the filtering portion 21.
According to a preferred embodiment, as shown in FIG. 3, in addition to the filter holes 210 being arranged in a "tapered" manner, a plurality of retention portions 211 arranged at intervals along the extending direction of the filter holes 210 may be formed inside each filter hole 210. Specifically, as shown in fig. 4, the indwelled portion 211 distant from the filter orifices extends radially inward of the filter orifices 210 as compared with the indwelled portion 211 near the filter orifices, and in the direction of extension of the filter orifices 210, as shown in fig. 5, the indwelled space of the annular indwelled surface 215 defined in the circumferential direction of the filter orifices 210 as compared with the indwelled portion 211 distant from the filter orifices is smaller than the annular indwelled surface 215 defined in the circumferential direction of the filter orifices 210 as compared with the indwelled portion 211 near the filter orifices, that is, the indwelled space of the annular indwelled surface 215 defined in the circumferential direction of the filter orifices 210 by each indwelled portion 211 is gradually reduced in the direction of extension of the filter orifices 210.
Specifically, as shown in fig. 4 and 5, the indwelling portion 211 has a circular ring shape as viewed in the direction in which the filter holes 210 extend, and each indwelling portion 211 is integrally connected in a stepped shape as viewed in the radial direction of the filter holes 210. Further, the detaining portion 211 may be formed by partially protruding the filtration pores 210 inward in the radial direction.
According to a preferred embodiment, as shown in FIG. 4, each of the retention portions 211 may be disposed at a predetermined angle α or β with respect to the filtration pore wall surface 214 of the filtration pore 210, wherein the retention portion 211 has a predetermined angle β with respect to the upper wall surface of the filtration pore 210 and the retention portion 211 has a predetermined angle α with respect to the lower wall surface of the filtration pore 210. In particular, as for any one of the detaining portions 211, it is projected in an inclined form with respect to the central axis of the filtering hole 210 extending radially along the filtering hole 210 and developed circumferentially around the inner wall, and preferably, the inclined direction of the detaining portion 211 is in an acute angle form with respect to the bottom of the wine retort bottom pot 10.
According to a preferred embodiment, when the filtering hole 210 is a tapered opening and the filtering hole 210 is internally provided with a tilted retention part 211, the predetermined included angle α of the retention part 211 relative to the lower wall surface of the filtering hole is an acute angle and can be selected in the range of 60-75 °; the preset included angle beta of the retention part 211 relative to the lower wall surface of the filter hole is an obtuse angle and can be selected within the range of 135-150 degrees. In particular, when the filter holes 210 are conventional parallel-type openings, α and β are complementary angles.
According to a preferred embodiment, as shown in fig. 5, the annular projecting surface of each of the retention portions 211 constitutes a retention surface 215 for blocking inflow of fermented grains particles as viewed in the extending direction of the filtering hole 210, and for any of the retention portions 211, the first surface pitch 212 of the retention surface 215 of each retention portion 211 close to the bottom of the filtering hole 210 is preferably larger than the second surface pitch 213 of the retention surface 215 close to the top of the filtering hole 210, that is, the retention surface 215 of each retention portion 211 is tapered from the bottom of the filtering hole 210 to the top thereof in the vertical direction, in other words, the retention space of each retention portion 211 relative to the retention surface 215 close to the bottom is larger than the retention space of the retention surface 215 relatively far from the bottom. In particular, the inter-planar distance may refer to the distance that any dwell 211 transitions radially to another dwell 211 that is adjacent.
According to a preferred embodiment, as shown in fig. 5, when the inside of the filtering hole 210 is constructed with the retention part 211 protruded in a radial direction, when the water at the bottom of the pot with the fermented grains flows in along the extending direction of the filtering holes 210, the retention surface 215 of the retention part 211 can generate certain blocking effect on the fermented grains, so that the fermented grains are at least partially retained on the surface area of the retention surface 215 to prevent the fermented grains from entering the deep part of the filtering holes 210 along with the water flow, and further, since the retention surface 215 of the retention part 211 is disposed at a predetermined inclination with respect to the wall surface 214 of the filtration pores, particularly the central axis of the filtration pores 210, most of the blocked fermented grains fall to the bottom along the inclined retention surface 215 and accumulate, and the range of the surface area of each of the remaining surfaces 215 closer to the bottom of the filtering holes 210 is larger than the range of the surface area farther from the bottom of the filtering holes 210, so as to adapt to the condition that most of fermented grains fall to the bottom due to gravity or inertia.
According to a preferred embodiment, as shown in fig. 5, as the number or volume of fermented grains accumulated or retained on the surface area of the retention surface 215 of the retention portion 211 increases, when the water flow flowing into the filtration pores 210 flows on the internal retention surface 215 thereof, the water flow forms a vortex on the annular surface area of the retention surface 215 of each retention portion 211, and the vortex can lift the fermented grains deposited on the bottom of the retention surface 215 to float, but because the annular retention surface 215 is provided in a predetermined inclined state, when the water flow on the bottom of the vortex flows along the annular surface area of the retention surface 215, the water flow can lift the fermented grains, and when the fermented grains float to the area of the retention surface 215 having an angle of β with the upper wall surface of the filtration pores, the water flow will follow the inclined wall surface 214 of the filtration pores to attach the fermented grains to the surface area thereof, and when the water flow tends to be stable, the fermented grains will fall down along the inclined retention surface 215, in particular, when the filtering holes 210 are "tapered" openings, the remaining surface 215 has an angle α with the lower wall surface of the filtering hole, and the deposited fermented grains at the top can float along the inclined wall surface 214 of the filtering hole 210 at the lower part and flow out in the direction of the filtering hole opening, thereby reducing the amount of the fermented grains deposited to the filtering hole 210, especially the bottom of the remaining surface 215.
According to a preferred embodiment, as shown in fig. 4 and 5, when the fermented grains flow to the deep part along the extending direction of the filtering hole 210, each retention surface 215 arranged along the circumferential direction can generate a certain retention effect on the fermented grains, and the retention space defined by each retention surface 215 of each retention part 211 is gradually reduced along the radial direction along the extending direction of the filtering hole 210, so that the blocking and filtering effects on the fermented grains with different grain sizes are further enhanced.
According to a preferred embodiment, when the water flow flows along the channel inside the filtering pores 210, the flow velocity is increased toward the outlet direction due to the "tapered" opening, and thus some fine fermented grains attached to the water flow may penetrate through the filtering pores 210 due to the increased flow velocity, so that, in the present invention, in regard to the detained surface of each detained portion 211, in addition to the detained surface 215 of each detained portion 211 being disposed in a manner of being tapered from the bottom of the filtering pore 210 toward the top thereof in the vertical direction, the area of the annular detained space or the surface area detained by the detained surface 215 of each detained portion 211 in the radial direction may be gradually increased in the extending direction of the filtering pores 210, that is, the surface area space of the detained surface 215 closer to the inlet of the filtering pores is smaller than the surface area space of the detained surface 215 farther from the inlet of the filtering pores, whereby when some fine fermented grains are deep into the filtering pores 210 as the water flow, the relative increase of the surface area space of the internal retention surface 215 can further prevent the grains from entering, and the stepped structure formed by integrally connecting the plurality of retention parts 211 in the filtering hole 210 can increase the kinetic energy of the water flow flowing out from the outlet of the filtering hole, so as to enhance the flushing effect on the impurities attached to the wall surface of the pressure guide pipe 206.
According to a preferred embodiment, the bottom water filtered most of the fermented grains flows to the clamping portion 22 at the bottom of the filtering portion 21 along the first liquid flow passage based on the gravity, and flows out into the pressure guiding pipe 206 via the second liquid flow passage inside the clamping portion 22 and communicated with the first liquid flow passage.
According to a preferred embodiment, the filter portion 21 and the catching portion 22 may be integrally formed, and the respective flow passages of the filter portion 21 and the catching portion 22 may integrally communicate.
According to an optional embodiment, in order to prevent fermented grains filtered by the filtering hole 210 from flowing into the pressure pipe 206 through the gap between the pressure sampling hole and the clamping portion 22, the diameter of the portion of the clamping portion 22 close to the side of the filtering portion 21 without the external thread structure may be slightly larger than that of the portion of the lower end thread structure, so that when the clamping portion 22 is connected to the pressure sampling hole through the external thread structure at the lower end thereof, the bottom surface of the clamping portion 22 without the thread structure can abut against the bottom of the cavity of the wine retort bottom pot 10, thereby filling the joint gap between the pressure sampling hole and the clamping portion 22.
According to a preferred embodiment, as shown in FIG. 1, the bottom of the filter element 201 is fluidly connected to a pressure pipe 206, and the other end of the pressure pipe 206 is connected to a tee 203. Fig. 3 shows a schematic cross-sectional structure of a tee 203 of the present invention in a preferred embodiment.
According to a preferred embodiment, tee 203, shown in FIG. 1, is comprised of a first conduit extending in the direction of flow of pressure pipe 206 and in fluid communication with an axial end of pressure pipe 206, and a second conduit connected radially to the first conduit and arranged at a predetermined angle relative to each other. In some alternative embodiments, the angle between the first conduit and the second conduit is between about 30 ° and about 60 °, preferably between about 35 ° and about 50 °, and more preferably about 45 °. Preferably, the diameter of the first conduit of tee 203 is the same as the diameter of pressure pipe 206, and the diameter of the second conduit may be the same or different than the diameter of pressure pipe 206.
According to a preferred embodiment, as shown in fig. 1, the second conduit extends obliquely along the side facing away from the ground, and a micro differential pressure transmitter 202 for level measurement is mounted at the port of the second conduit remote from the first conduit.
According to a preferred embodiment, as shown in fig. 1, the end of the first vertically extending conduit of the tee 203 facing away from the pressure pipe 206 is connected to a settling tube 204. In particular, the settling tube 204 needs to be inspected and drained periodically, depending on the frequency of use of the wine retort. And preferably, in the present invention, the settling tube 204 may be made of stainless steel.
According to a preferred embodiment, the diameter and length of the settling tube 204 can be determined according to the usage effect of the filter element 201 and the frequency of flushing the pressure pipe 206, so as to avoid the volume of the settling tube 204 not matching with the settling volume to cause the blockage of the pressure pipe 206.
According to a preferred embodiment, as shown in fig. 1, the end of the settling pipe 204 facing away from the first conduit of the tee 203 is provided with a discharge valve 205, the discharge valve 205 can be used for controlling the flow rate of the discharged bottom water, and the bottom water can be discharged by opening the discharge valve 205, and the bottom water can smoothly carry out the cleaning of impurities deposited or adhered on the inner wall of the pipe. Preferably, in the present invention, the discharge valve 205 may be a stainless steel ball valve.
According to a preferred embodiment, the detection process of the micro differential pressure transmitter 202 is: gradually adding bottom water to be measured into the wine retort bottom pot 10 under the state that the discharge valve 205 is closed, wherein the bottom water flows through the filtering element 201, the pressure guide pipe 206, the three-way pipe 203 and the settling pipe 204 in sequence, reading a pressure measurement value of the micro-differential pressure transmitter 202 after gradually adding the bottom water to the state that the bottom water does not pass through all the filtering holes 210 of the filtering element 201, and taking the pressure measurement value as a liquid level zero value of the wine retort bottom pot 10.
According to a preferred embodiment, the principle of the micro differential pressure transmitter 202 is: in the process that the boiler bottom water sequentially flows into the settling pipe 204, the three-way pipe 203 and the pressure guide pipe 206 due to gravity, at least part of the boiler bottom water flows along the extension direction of the second pipe and synchronously raises the liquid level to be in contact with the micro differential pressure transmitter 202 while the boiler bottom water flows upwards along the first pipe of the three-way pipe 203.
Further, the boiler bottom water enters the high and low pressure chambers of the micro differential pressure transmitter 202, and acts on the isolation diaphragms at both sides of the sensing element, and is transmitted to both sides of the measurement diaphragm through the isolation diaphragms and the filling liquid boiler bottom water in the sensing element, and the electrodes of the measurement diaphragms at both sides and the insulation sheet respectively form a capacitor. In particular, when the pressures of the two measuring diaphragms are not consistent, the measuring diaphragm generates displacement in direct proportion to the pressure difference, and the capacitance on the two sides is not equal, and the capacitance is converted into a signal in direct proportion to the pressure through the oscillation and demodulation steps. Preferably, micro-differential pressure transmitter 202 is capable of withstanding 20KPa negative pressure.

Further, in the process of adding or subtracting the liquid level of the wine retort bottom pot 10 at the later stage, the liquid level value is continuously changed in the range from the zero value to the full range.
