The utility model is further described below with reference to fig. 1 to 5.

Example 1

In order to solve the technical problems in the background technology, the utility model provides a direct-blowing roller spreading and airing machine which is mainly used for cooling vinasse.

In the concrete technical scheme, referring to fig. 1, the direct blowing type roller spreading and airing machine comprises a frame 1, wherein the frame 1 is used as a main installation and bearing part, a hollow rotatable stirring bin 2 and a power component 5 for driving the stirring bin 2 to rotate are horizontally arranged on the frame 1 for facilitating conveying and cooling of vinasse, a feeding bin 3 connected with the frame 1 is movably connected to one side of the stirring bin 2 for facilitating material entering and outputting the stirring bin, a discharging bin 4 connected with the frame 1 is movably connected to the other side of the stirring bin 2, a feeding hopper 301 is communicated with the top of the feeding bin 3, a discharging hole 401 is formed in the bottom of the discharging bin 4, and stirring blades 201 in spiral arrangement are arranged on the inner wall of the stirring bin 2 for achieving conveying and cooling of vinasse in the stirring bin 2, and the stirring blades 201 are used for stirring and conveying the materials in the stirring bin 2, and the direct blowing type roller spreading and airing machine further comprises a cooling component 6 and a cooling component 6 for cooling the materials in the stirring bin 2.

The working principle of the direct blowing type roller spreading and airing machine is that distilled vinasse is poured into a feed hopper 301 through a transfer device, the vinasse enters a stirring bin 2 through the feed hopper 301, a power assembly 5 is started, the power assembly 5 drives the stirring bin 2 to rotate, and as stirring blades 201 are arranged in the stirring bin 2, the vinasse is gradually conveyed to one side, close to a discharging bin 4, of the stirring bin 2 from one side, close to the feeding bin 3, of the stirring bin 2 in the process of rotation of the stirring bin 2, and finally falls into a hopper 10 below through a discharging hole 401.

The structure is the same as that of the roller spreading and airing machine in the background art, but the cooling mode of the roller spreading and airing machine in the background art is mainly that the fermented grains in the stirring bin transfer heat to the cooling bin through the bin wall of the cooling bin, and then cooling air is introduced into the cooling bin to take away the heat in the cooling bin. Therefore, the technical problems that the cooling efficiency is low, and the material is easy to leak into the cooling bin, so that the material cleaning difficulty is high are solved. To this end, in view of the above technical problems, the present embodiment makes the following further improvements to the cooling assembly:

Referring to fig. 1 and 2, the cooling assembly 6 includes an air outlet 601 horizontally disposed on a side wall of the feeding bin 3 and communicated with the stirring bin 2, and an air inlet 602 horizontally disposed on a side wall of the discharging bin 4 and communicated with the stirring bin 2, and a fan 603 is disposed in the air inlet 602, and the fan 603 adopts an axial flow fan.

The working principle of the cooling component is that in the process of rotating the stirring bin 2, namely in the process of conveying the vinasse, the fan 603 is started, the fan 603 extracts external normal-temperature natural wind into the stirring bin 2 through the air inlet 602, the natural wind entering the stirring bin 2 exchanges heat with the high-temperature vinasse, and the stirring bin 2 is of a closed structure, so that the high-temperature gas which completes heat exchange with the vinasse is discharged through the air outlet 601. In order to reduce the running resistance of the cooling air in the stirring bin 2, the air outlet 601 and the air inlet 602 may be concentrically arranged, and are preferably arranged in the middle of the feeding bin 3 and the discharging bin 4.

Compared with an indirect cooling mode of a roller spreading and airing machine in the prior art, the direct cooling device has the advantages that cooling air is directly introduced into the stirring bin, so that the cooling air is in direct contact with the vinasse, and the vinasse is directly cooled by the cooling air, so that the direct blowing type roller spreading and airing machine shortens the cooling time, improves the cooling efficiency, and simultaneously can avoid the problem of high cleaning difficulty caused by material leakage. In the background art, the time for cooling the distilled grains of the steamer by the roller spreading and airing machine is 25-30 min, and the time for cooling the distilled grains of the steamer by the direct blowing roller spreading and airing machine is 12-15 min, so that the cooling efficiency is improved by about 1 time.

Referring to fig. 1, the power assembly 5 is specifically configured in such a manner that the power assembly 5 includes a gear motor 501 disposed on the frame 1, an output end of the gear motor 501 is connected with a gear 502, a rack 503 matched with the gear 502 is disposed on an outer wall of the stirring bin 2, and the gear 502 is in meshing connection with the rack 503.

The working principle of the power assembly 5 is that a gear motor 501 is started, the gear motor 501 drives a gear 502 to synchronously rotate, and the gear 502 is in meshed connection with a rack 503, so that the stirring bin 2 connected with the rack 503 is driven to rotate in the rotating process of the gear 502.

In order to protect the rack 503, referring to fig. 1, the present embodiment is further provided with a dust cover 504 on the outer side of the rack 503. A dust screen 606 is provided on the air inlet 602.

Wherein, in order to make stirring storehouse 2 rotate more steadily, this embodiment still is provided with supplementary rolling subassembly 7.

Specifically, referring to fig. 2, the auxiliary rolling assembly 7 includes two guide rails 701 disposed on the outer wall of the stirring chamber 2, and the frame 1 is provided with auxiliary wheels 702 matched with the guide rails 701, and the guide rails 701 are connected with the auxiliary wheels 702 in a rolling manner. The auxiliary wheel can assist the stirring bin 2 to rotate, so that the stress point of the stirring bin 2 is increased, and the rotation process of the stirring bin 2 is more stable.

Example two

In fact, the working principle of the direct-blowing type roller spreading and airing machine is similar to that of a traditional cement stirring tank, required materials are realized by rotating a stirring bin, the cement stirring tank is not required to be used for completing the mixing of the materials, and the roller spreading and airing machine is used for realizing the conveying and cooling of the materials. Therefore, the roller spreading and airing machine is limited by the weight of the vinasse in the process of conveying the vinasse, most of the vinasse can be piled up at the bottom of the stirring bin in the process of rotating the stirring bin, and the contact area of the vinasse piled up at the bottom of the stirring bin with cooling air is small, so that the heat dissipation and cooling efficiency of the vinasse can be reduced. For this reason, in view of the above technical problems, on the basis of the first embodiment, this embodiment makes the following further improvements:

Specifically, referring to fig. 4, in this embodiment, a shoveling plate 202 perpendicular to the inner wall of the stirring bin 2 is disposed on the stirring blade 201, and the shoveling plate 202 may be disposed at a level with or lower than the top of the stirring blade 201, so as to spread and accelerate heat dissipation of the material.

The working principle of the shoveling plate is that in the rotation process of the stirring bin 2, when the shoveling plate 202 is positioned at the bottom of the stirring bin 2, the shoveling plate 202 synchronously rotates along with the stirring bin 2 along with the rotation of the stirring bin 2, the shoveling plate 202 gradually rotates from the bottom of the stirring bin 2 to the top of the stirring bin 2, and in the rotation process, vinasse at the bottom of the stirring bin 2 can be accumulated into an included angle formed between the shoveling plate 202 and the inner wall of the stirring bin 2. That is, the shoveling plate 202 will hold up the stillage, thereby avoiding the stillage from accumulating at the bottom of the stirring bin 2. When the shoveling plate 202 is positioned at the top of the stirring bin 2 and starts to move towards the bottom of the stirring bin 2, the shoveling plate 202 cannot hold the wine lees, and the wine lees fall off the shoveling plate 202. In the process that the vinasse falls from the top of the stirring bin 2, the vinasse can be fully contacted with cooling air, so that the contact area of the vinasse and the cooling air is increased, the cooling efficiency is greatly improved, and meanwhile, the fallen vinasse has certain potential energy, so that the effect of scattering the vinasse can be achieved. Because the water content of the distilled grain is large, the phenomenon of agglomeration and knotting can occur.

Example III

Because distillers' grains are fermented and distilled, exhaust gas, i.e., waste gas, is generated during spreading and airing, and the exhaust gas is filled in the environment to affect staff. For this reason, in view of the above technical problems, on the basis of the first embodiment, this embodiment makes the following further improvements:

Specifically, referring to fig. 5, in this embodiment, an air pipe joint 604 is hermetically connected to an air outlet 601, an air outlet pipe 605 is connected to the air pipe joint 604, and a condenser 8 is connected to an end portion of the air outlet pipe 605.

The working principle is that high-temperature gas after heat exchange with the vinasse in the stirring bin 2 enters the air outlet pipe 605 through the air outlet 601, then enters the condenser through the air outlet pipe 605, and finally is condensed into liquid through the condenser. In order to further realize the sealing of the stirring bin 2, after the vinasse completely enters the stirring bin 2, a cover plate matched with the vinasse in shape can be covered on the feeding hopper 301, or the cover plate can be hinged with the feeding hopper 301 and can open and close the feeding hopper 301 in a turnover mode. The condenser is a prior art device, and the structure and working principle thereof are not described herein.

According to the structure and the working principle, the direct-blowing type roller spreading and airing machine adopts a fully-closed mode, and can condense the exhaust gas subjected to heat exchange into liquid for collection, so that the exhaust gas subjected to heat exchange is prevented from leaking into the environment, and the air quality of the environment is ensured.

During the spreading and airing process of the vinasse, yeast or dressing auxiliary materials are added into the vinasse according to different types of vinasse. The yeast is convenient for fermentation of distiller's grains in cellar, and the adjuvant is bran shell which can loosen distiller's grains and facilitate subsequent distillation. The roller spreading and airing machine in the prior art can not add yeast and auxiliary materials in the stirring bin. In addition, the traditional brewing process is also to divide the yeast adding process and the auxiliary material adding process into different brewing processes, and cannot be completed in the same process. Therefore, the embodiment further improves the following technical problems on the basis of the first embodiment, and the embodiment further comprises a feeding assembly, wherein the feeding assembly is used for feeding auxiliary materials into the stirring bin.

Specifically, referring to fig. 5, the feeding assembly of the present embodiment includes a horizontally arranged screw conveyor 9, one end of the screw conveyor 9 extends deep into the stirring hopper 2, and the other end extends to the outside of the stirring hopper 2 through an air pipe joint 604. The screw conveyor 9 is a prior art device, and the structure and operation principle thereof are not described in detail here.

The working principle is that when yeast or auxiliary materials are required to be added into the vinasse in the stirring bin 2 in the process of spreading and airing the vinasse, the yeast or auxiliary materials are added into the screw conveyor through a feed inlet of the screw conveyor 9, and fall onto the vinasse in the stirring bin 2 through a discharge port of the screw conveyor 9, and are mixed and stirred by the stirring bin 2. The number of the screw conveyors 9 can be determined according to the field installation of the equipment, one screw conveyor 9 can be directly adopted, and two screw conveyors 9 can be adopted for splicing.

According to the structure and the working principle, the yeast required by the fermentation of the vinasse and the auxiliary materials required by the distillation of the vinasse can be added into the stirring bin, that is, the yeast adding process and the auxiliary materials adding process can be synchronously completed in the spreading and airing process, and the three processes are completed in one process, so that the efficiency is greatly improved, and the functionality of equipment is improved.

Example IV

A welding mode is adopted between the stirring blades and the stirring bin of the roller spreading and airing machine in the prior art. In the actual spreading and airing process, the spreading and airing times required for different types of stillage and different amounts of stillage are different. The time of airing of the vinasse in the stirring bin is controlled in two ways, one way is to control the rotating speed of the stirring bin, the other way is to replace stirring blades with different specifications, the distance between the blades of the stirring blades with different specifications is different, and the length of the path of the vinasse on the stirring blades is different, so that the purpose of controlling the time of airing of the vinasse is achieved. In the prior art, the stirring blades and the stirring bin of the roller spreading and airing machine are welded, so that the spacing between adjacent blades of the stirring blades cannot be adjusted. For this reason, in view of the above technical problems, on the basis of the first embodiment, this embodiment is further improved as follows:

In this embodiment, the stirring vane 201 and the stirring bin 2 are detachably connected, an ear plate (not shown in the figure) is arranged on the stirring vane 201, and the stirring vane 201 is connected with the stirring bin 2 through the ear plate by bolts (not shown in the figure).

According to the structure and the working principle, the stirring blade is connected with the stirring bin in a detachable mode, so that the stirring blades with different specifications are convenient to replace, and the stirring blade is convenient to maintain and clean.

The foregoing detailed description of the utility model has been presented for purposes of illustration and description, and it should be understood that the utility model is not limited to the particular embodiments disclosed, but is intended to cover all modifications, equivalents, alternatives, and improvements within the spirit and principles of the utility model.
