For a further understanding of the invention, its features and advantages, reference is now made to the following examples, which are illustrated in the accompanying drawings.
The structure of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1-3, the culture water filtering device provided by the embodiment of the invention includes a housing 1 and a filter screen 2, the housing 1 has a water inlet 3 and a water outlet 4, the filter screen 2 is located between the water inlet 3 and the water outlet 4, and further includes:
a filter cartridge 6 with a first filter hole 5, wherein the filter cartridge 6 is positioned above the filter screen 2, the filter cartridge 6 is a cylinder, a first water delivery component 7 is communicated with the upper side of the side wall of the filter cartridge 6, and the upper end of the first water delivery component 7 is communicated with the water inlet 3;
the filter cartridge 6 one end has driving motor 8, driving motor 8's output fixedly connected with pivot 9, fixedly connected with first helical blade 10 in the pivot 9, the one end intercommunication of filter cartridge 6 has a ejection of compact section of thick bamboo 11, the one end of ejection of compact section of thick bamboo 11 extends to the casing 1 outside.
Through the above-mentioned setting, pour into the breeding water into water inlet 3 in, enter into cartridge filter 6 through first water delivery subassembly 7, filter excrement granule and dead fish shrimp in advance through cartridge filter 6, then the breeding water after the filtration in advance passes through filter screen 2 under the action of gravity to suspended particles wherein filtering. The problems that suspended particles, excrement particles and dead fishes and shrimps are all piled up on the filter screen 2, so that excessive impurities are piled up on the piled filter screen 2, the filtering efficiency is reduced and the filter plate is required to be replaced frequently can be avoided.
Wherein, the filter cartridge 6 carries out the process of prefiltering to excrement granule and dead fish shrimp and does: excrement particles and dead fish and shrimp enter the filter cartridge 6, and the driving motor 8 drives the first helical blade 10 to rotate through the rotating shaft 9, so that the excrement particles and the dead fish and shrimp are stirred into the discharging barrel 11, and the excrement particles and the dead fish and shrimp are discharged out of the shell 1 from the discharging barrel 11.
The dead fishes and shrimps are smaller fishes and shrimps, because the larger fishes and shrimps are filtered before entering the water inlet 3 and do not enter the device.
Further, referring to fig. 2, the filter cartridge 6 is disposed obliquely, the driving motor 8 is located at the outer side of the housing 1, the rotating shaft 9 rotates to penetrate through the housing 1 and extend into the filter cartridge 6, and the driving motor 8 is located obliquely above the filter cartridge 6. Through this setting, cartridge filter 6 slope sets up, makes the aquatic water be difficult for by oneself from cartridge filter 6 be close to driving motor 8's tip get into ejection of compact section of thick bamboo 11, and the impurity stirs ejection of compact section of thick bamboo 11 through first helical blade 10, realizes the separation of aquatic water and impurity. And, compared with the drive motor 8 positioned obliquely below the filter cartridge 6, the drive motor 8 positioned obliquely above is not easy to contact with the culture water body to damage.
Further, referring to fig. 2, the discharge cylinder 11 is disposed obliquely, and the oblique direction of the discharge cylinder 11 is opposite to the oblique direction of the filter cylinder 6, so that the obliquely disposed discharge cylinder 11 is convenient for discharging impurities. By this arrangement, impurities can be discharged from the housing 1 in the discharge vessel 11 under the force of gravity.
For example, referring to fig. 4, the first water delivery assembly 7 includes an upper accommodating cylinder 13 and a lower accommodating cylinder 14 which are communicated through a water delivery channel 12, and the water delivery channel 12 is obliquely arranged, the axis of the water delivery channel 12 is parallel to the axis of the rotating shaft 9, the upper end of the upper accommodating cylinder 13 is communicated with the water inlet 3, and the lower end of the lower accommodating cylinder 14 is communicated with the filter cartridge 6;
referring to fig. 5 and 6, the water delivery channel 12 has a connecting rod 15, a filter cover 16 is fixedly connected to an upper end of the connecting rod 15, the filter cover 16 is located in the upper accommodating cylinder 13, the filter cover 16 is a conical filter cover, an apex of the filter cover 16 faces upwards, and a second filter hole 17 is formed in the filter cover 16.
With this arrangement, when the filter housing 16 blocks the upper end of the water delivery channel 12, the fecal pellets are carried by the body of aquaculture water through the second filter hole 17 into the filter cartridge 6, and dead fish and shrimp are blocked and left in the upper containment drum 13. The benefit of the filter housing 16 being a tapered filter housing is that the filter housing 16 is not obstructed by fish and shrimp.
When a predetermined time has elapsed, the connecting rod 15 moves obliquely upward in the axial direction, and a gap is provided between the filter housing 16 and the upper end of the water delivery passage 12, so that the fish and shrimp accumulated in the upper accommodating tube 13 flow into the filter cartridge 6 through the gap, and the filter housing 16 filters the fish and shrimp.
Further, the following exemplary description of how the connecting rod 15 moves: one side of the water delivery channel 12 is provided with a first slide way 18, one side of the connecting rod 15 is fixedly connected with a first deflector rod 19, the first deflector rod 19 is slidably connected with the first slide way 18, and one end of the first deflector rod 19 extends out of the water delivery channel 12. By pulling the first deflector rod 19, the connecting rod 15 can be moved up and down in the axial direction, so that the filter cover 16 blocks the upper end of the water delivery channel 12.
Further, referring to fig. 4, a collar 20 is fixedly connected to one end of the first lever 19; the second helical blade 21 is fixedly connected to the rotating shaft 9, the edge of the second helical blade 21 is made of flexible materials, the edge of the second helical blade 21 is in interference fit with the inner wall of the lantern ring 20, and the rotation directions of the second helical blade 21 and the first helical blade 10 are opposite. Through this setting, when the second helical blade 21 is driven downwards by the rotation shaft 9 to dial the first deflector 19 downwards, the first deflector 19 drives the connecting rod 15 and the filter cover 16 to move downwards in sequence, so that the filter cover 16 blocks the upper end of the water delivery channel 12, at this time, the excrement particles are driven by the aquaculture water body to enter the filter cartridge 6 through the second filter hole 17, and the fish and shrimp are blocked and remain in the upper accommodating cylinder 13. And since the second helical blade 21 and the first helical blade 10 are opposite in rotation direction, the rotating shaft 9 drives the first helical blade 10 to rotate at the moment, and the excrement particles are stirred upwards to be discharged. When the set time is reached, the number of fish and shrimp in the upper accommodating cylinder 13 is accumulated to a certain extent, and the rotating shaft 9 is reversely rotated, so that the connecting rod 15 moves obliquely upward along the axial direction, a gap is formed between the filter cover 16 and the upper end of the water delivery channel 12, and the fish and shrimp accumulated in the upper accommodating cylinder 13 flow into the filter cartridge 6 through the gap.
Further, a cleaning tube 23 inclined upward is connected to one side of the upper accommodating cylinder 13, and the cleaning tube 23 extends to the outside of the housing 1 through the housing 1. With this arrangement, when the filter housing 16 is clogged, the filter housing 16 can be opened by an external opening device or by a hand extending into the device.
Further, referring to fig. 7, an inner cylinder 24 is disposed on the inner side of the filter cartridge 6, and an inner cylinder filter hole 25 is formed on the inner cylinder 24; the overlapping dimensions of the inner cartridge filter holes 25 and the first filter holes 5 can be varied. In particular, the overlapping dimensions of the inner cartridge filter holes 25 and the first filter holes 5 can be changed by rotating the inner cartridge 24 or axially moving the inner cartridge 24.
For example, the inner cylinder 24 is fixedly connected with a second shift lever 26, and one end of the second shift lever 26 penetrates through the housing 1 and extends to the outer side of the housing 1. The overlapping size of the inner cylinder filter holes 25 and the first filter holes 5 is changed by pushing and pulling or left and right pulling the second deflector rod 26.
In this embodiment, the overlapping dimensions of the inner cylinder filter holes 25 and the first filter holes 5 can be changed, so that the filtering efficiency can be improved. For example, if the particles of the excrement particles are large, the excrement particles are not passed even if the overlapping sizes of the inner tube filter holes 25 and the first filter holes 5 are relatively large, and at this time, the overlapping sizes of the inner tube filter holes 25 and the first filter holes 5 are correspondingly large, and at this time, the filtering efficiency can be improved. In this case, the edge of the first helical blade 10 is fitted to the inner surface of the inner cylinder 24, so that the discharge is more complete. Here, the relative increase in the overlapping size of the inner tube filter hole 25 and the first filter hole 5 is relative to the size of the excrement particles, so that the excrement does not pass through. This function is used in a manner that requires the inner barrel 24 to be secured after adjustment.
Further, referring to fig. 5, the side edges of the first helical blade 10 are equidistantly provided with flexible stirring members 27, and the outer surface of the flexible stirring members 27 can be attached to the inner surface of the inner cylinder 24.
In this embodiment, the flexible stirring member 27 is an elastic rubber layer, and when the first helical blade 10 rotates, the inner cylinder 24 can be stirred to move by the flexible stirring member 27, and when the first helical blade 10 rotates in the discharging direction, the inner cylinder 24 is made to rotate in one direction, so that the overlapping size of the inner cylinder filter hole 25 and the first filter hole 5 is minimized, and the excrement particles can be filtered. When the first helical blade 10 rotates to the other direction, the inner cylinder 24 rotates to the other direction, the superposition size of the inner cylinder filter hole 25 and the first filter hole 5 reaches the maximum, and the inner cylinder filter hole 25 is used for filtering dead fishes and shrimps.
First, the size of the overlapping dimensions of the inner tube filter hole 25 and the first filter hole 5 is smaller than the volume of the excrement particles and dead fish and shrimp, when the excrement enters the filter cartridge 6, the excrement can be filtered, and the excrement particles can be discharged in time through the first spiral blade 10, so that the excrement particles are not broken and are fused into the culture water body. When dead fish and shrimp enter the filter cartridge 6, the amount of faecal particles is negligible, and in order to increase the filtration efficiency, the overlapping size of the two is maximized, so long as the dead fish and shrimp cannot pass, and even if a small amount of faecal particles pass, filtration can still be performed when suspended filtration is possible.
It should be further noted that, assuming that the overlapping dimensions of the inner cylinder filter hole 25 and the first filter hole 5 cannot be changed, only the dimension capable of filtering out the excrement particles can be set, the filtering efficiency of the arrangement is always fixed to a small extent, which is obviously disadvantageous for improving the filtering efficiency compared with the present device. The above-mentioned meaning of separating fish and shrimp from faecal particles is that.
It should be noted that the sense of the forward and reverse rotation of the first helical blade 10 is that: the dead fish and shrimp block the first filtering holes 5 to reduce the efficiency of the first filtering holes 5 for filtering the culture water, and the first helical blades 10 push the dead fish and shrimp to one side far away from the discharging barrel 11, so that the dead fish and shrimp can not block the first filtering holes 5. When the rotating shaft 9 is reversely rotated again, the first helical blade 10 reversely rotates to stir the dead fish and the shrimp and the excrement particles to enter the discharging cylinder 11 together.
Further, in an alternative embodiment, the flexible stirring member 27 may be provided as a flexible brush, and the flexible brush may be inserted into the overlapping portion of the inner cylinder filter hole 25 and the first filter hole 5. The first helical blade 10 can drive the flexible brush to rotate when rotating, so that the flexible brush is inserted into the inner cylinder filter hole 25 and the first filter hole 5, and the inner cylinder filter hole 25 and the first filter hole 5 are prevented from being blocked.
Further, referring to fig. 8 and 9, in order to facilitate the pulling of the second lever 26, the housing 1 has an arc hole 28, the second lever 26 is slidably disposed in the arc hole 28, and a limiting member 29 for limiting the rotation angle of the second lever 26 is disposed on the outer wall of the housing 1.
The limiting piece 29 comprises a limiting sleeve 30, the limiting sleeve 30 is fixedly connected to the outer wall of the shell 1, a sliding rod 31 is slidably connected to the limiting sleeve 30, a locking screw 32 is rotatably connected to the limiting sleeve 30 through threads, the end portion of the locking screw 32 can press the sliding rod 31, a V-shaped limiting rod 33 is fixedly connected to the end portion of the sliding rod 31, and the second deflector rod 26 is located between the V-shaped limiting rods 33. By this arrangement, the V-shaped stopper rod 33 is moved up and down, and the left-right swing width of the second deflector rod 26 can be restricted, so that the appropriate overlapping size of the inner cylinder filter hole 25 and the first filter hole 5 can be adjusted. The V-shaped stop lever 33 can also lock the second shift lever 26, thereby locking and fixing the second shift lever 26.
Further, referring to fig. 10-12, in order to facilitate replacement of the filter screen 2, the housing 1 is provided with symmetrically arranged mounting holes 34, the inner wall of the housing 1 is provided with a second slide way 35, and the filter screen 2 is arranged in the mounting holes 34 and the second slide way 35; the two opposite outer walls of the shell 1 are connected with baffle plates 37 through elastic pieces 36, the two opposite outer walls of the shell 1 are fixedly connected with limiting plates 38, and the two baffle plates 37 are respectively and slidably connected in the two limiting plates 38; the baffle 37 has a water blocking layer 39 on a side close to the housing 1, and the water blocking layer 39 can block the mounting hole 34.
In the present embodiment, the elastic member 36 is provided as a spring, and the baffle 37 shields the filter screen 2 during normal use of the filter screen 2, and the water blocking layer 39 prevents the installation hole 34 from leaking water. When the filter screen 2 needs to be replaced, the baffle 37 is pulled out, so that the lower edge of the baffle 37 is attached to the upper surface of the filter screen 2. At this time, the old filter screen can be ejected out by the new filter screen, and the filter screen can be replaced without stopping. In the process that the new filter screen ejects the old filter screen, the baffle 37 on one side is elastically attached to the old filter screen, and the baffle 37 on the other side is elastically attached to the new filter screen, so that the water leakage amount when the filter screen 2 is replaced is reduced. The baffle 37 can also block part of the water outlet 4, and the size of the water outlet 4 is adjusted.
