DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the implementation mode of the present application clearer, the technical solution in the implementation mode of the present application will be clearly and completely described in combination with the drawings in the implementation mode of the present application. Obviously, the described implementation mode is a part of the implementation mode of the present application, not all the implementation modes. Based on the implementation mode in the present application, all other implementation modes obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. The specific implementation modes of the present invention are described in detail in combination with the drawings in the specification.

[0022] like Figure 1-Figure 4 and Figure 7 As shown, a separation device for alcohol fermentation includes a housing component 1, a regulating component 2 and a separation component 3; The housing assembly 1 includes a separation tank 101; The separation component 3 includes an elastic spiral filter 301 and an elastic spiral sheet 302 arranged coaxially, the elastic spiral filter 301 and the elastic spiral sheet 302 are arranged in a spiral manner in a twisted manner, and each spiral layer of the elastic spiral sheet 302 is located below the corresponding spiral layer of the elastic spiral filter 301, a plurality of filter holes are provided on the top spiral surface of the elastic spiral filter 301, and a polyester filter cloth is fixedly installed on the top spiral surface of the elastic spiral sheet 302; The adjustment component 2 includes a compression component acting on the lower end of the elastic spiral filter 301 and a compression adjustment component acting on the elastic spiral sheet 302. The compression component is configured to drive the elastic spiral filter 301 to be compressed along the axial direction to adjust the spiral layer spacing thereof. The compression adjustment component includes a positioning arm 205 fixed to the upper end of the elastic spiral sheet 302, and a driving arm 213 driving the lower end of the elastic spiral sheet 302 to move along the axial direction. The compression adjustment component is configured to synchronously adjust the spiral layer spacing of the elastic spiral sheet 302 and the inter-layer distance between the elastic spiral sheet 302 and the elastic spiral filter 301.

[0023] Traditional filtering devices mostly use multi-layer filter screens arranged up and down for filtering. In the above structure of the present device, the elastic spiral filter screen 301 and the elastic spiral sheet 302 are spirally arranged in a twisted manner, and filter holes and polyester filter cloth are arranged thereon to form a two-stage filtering structure. The shape of the spiral arrangement can increase the filtering area, which can improve the impurity removal rate compared to the traditional filtering structure.

[0024] Traditional filtering devices mostly use filter layers with fixed spacing, and the filtering parameters cannot be adjusted. In the above structure of the present device, the spiral layer spacing of the elastic spiral filter 301 is adjusted by the compression component, so that the effective contact area of ​​the filter hole and the liquid flow rate can be changed to control the initial filtering efficiency. Then, according to the filtering effect of the elastic spiral filter 301, the spiral layer spacing of the elastic spiral sheet 302 is adjusted to control the filtering speed of the polyester filter cloth to achieve a rapid filtering effect. By dynamically matching the spiral layer spacing of the spiral filter 301 with the spiral layer spacing of the elastic spiral sheet 302, the efficiency loss problem caused by the coupling of multi-stage filtering parameters of the traditional device is solved.

[0025] By adjusting the spacing between the spiral layers of the elastic spiral filter 301 and the elastic spiral sheet 302, in some embodiments, Figure 7 As shown, when projected along the axis, the lowest spiral layer of the elastic spiral sheet 302 and the lowest spiral layer of the elastic spiral filter 301 form a semi-circular extension structure.

[0026] In the above structure of the present device, the fermentation liquid dripping from the end of the elastic spiral filter 301 can be accurately discharged into the polyester filter cloth on the top of the elastic spiral sheet 302, thereby improving the filtering effect; through the design of the semi-circular extended elastic spiral sheet 302, sufficient space can be reserved for the fermentation liquid dripping from the end of the elastic spiral filter 301, thereby improving the filtering effect.

[0027] In some embodiments, Figure 8-Figure 10As shown, the cleaning component 4 includes a partition piece 412 fixed to the inner wall of the separation tank 101 and a positioning cylinder 401 rotatably connected to the partition piece 412 , the elastic spiral filter 301 and the elastic spiral piece 302 are both sleeved on the outer periphery of the positioning cylinder 401 , and the upper end of the elastic spiral filter 301 is fixedly connected to the partition piece 412 .

[0028] A liquid conducting hole 413 is formed on the top of the partition plate 412 , the upper end of the elastic spiral filter 301 is fixedly connected to the inner wall of the liquid conducting hole 413 , and the inner ring spiral baffle 304 is in sliding contact with the outer periphery of the positioning tube 401 .

[0029] In the above structure of the device, the partition piece 412 can accurately pour the fermentation liquid into the elastic spiral filter 301.

[0030] In some embodiments, the filter holes on the elastic spiral filter 301 have a decreasing aperture from top to bottom along the spiral surface.

[0031] Traditional filters mostly use uniform pore sizes, which cannot adapt to the dynamic changes in the size of impurity particles during liquid flow. In the above structure of the present device, the filter holes gradually change in diameter from top to bottom. The large-pore filter holes on the upper layer intercept large impurities such as pectin and fiber, and the small-pore filter holes on the lower layer capture tiny particles such as yeast residues. Step-by-step screening prevents large particles from clogging the small-pore filter holes prematurely, thereby extending the service life of the filter.

[0032] In some embodiments, the density of the filter holes on the elastic spiral filter 301 decreases from top to bottom along the spiral surface.

[0033] Traditional filters often use a uniform pore density design, which causes the liquid flow rate to fluctuate with height and easily forms liquid accumulation pressure in local areas. In the above structure of the present device, the high pore density area in the upper layer can accelerate the initial diversion of the liquid and reduce the inlet pressure; the low pore density area in the lower layer can prolong the liquid retention time, enhance the adsorption and retention effect of small particle impurities, and improve the filtration efficiency.

[0034] In some embodiments, the mesh count of the polyester filter cloth increases from top to bottom along the spiral surface.

[0035] In traditional multi-stage filtration devices, the secondary filter cloth usually uses a single mesh number, which is difficult to match the impurity size distribution characteristics after the previous stage filtration. In the above structure of this device, the upper high-mesh filter cloth captures medium and large residual impurities, and the lower low-mesh filter cloth intercepts tiny particles.

[0036] In some embodiments, Figure 4 As shown, the housing assembly 1 further includes a tank cover 102 detachably mounted on the top of the separation tank 101 and a liquid inlet pipe 103 fixedly mounted on the top of the tank cover 102, and an end of the liquid inlet pipe 103 is connected to the alcohol fermentation device.

[0037] The detachable tank cover 102 supports opening and closing, and the interior of the separation tank 101 can be directly cleaned and maintained without disconnecting the liquid inlet pipe 103.

[0038] In some embodiments, Figure 4-Figure 6 As shown, a second sliding hole 1012 is provided on the outer wall of the separation tank 101, and the compression assembly includes a second adjusting frame 209, which is fixedly installed on the outer wall of the separation tank 101, and a second lifting hole 210 is provided on the outer wall of the second adjusting frame 209. A second connecting arm 211 is slidably connected to the inner wall of the second lifting hole 210, and a third adjusting screw 212 is rotatably connected to the inner wall of the second lifting hole 210. The top of the third adjusting screw 212 passes through the second adjusting frame 209 and extends to its outside, the third adjusting screw 212 passes through the second connecting arm 211 and is threadedly connected thereto, and the end of the second connecting arm 211 passes through the second sliding hole 1012 and is fixedly connected to the lower end of the elastic spiral filter 301.

[0039] The compression adjustment component includes a first adjustment frame 201, which is fixedly mounted on the outer wall of the separation tank 101, and a positioning arm 205 is fixedly mounted on the outer wall of the first adjustment frame 201. A first sliding hole 1011 is opened on the outer wall of the separation tank 101, and the end of the positioning arm 205 passes through the first sliding hole 1011 and extends to the interior of the separation tank 101. The end of the positioning arm 205 is fixedly connected to the upper end of the elastic spiral sheet 302.

[0040] A first lifting hole 202 is provided on the outer wall of the first adjusting frame 201, and a first slider 203 is slidably connected to the inner wall of the first lifting hole 202, and a driving arm 213 is fixedly connected to the end of the first slider 203, and the end of the driving arm 213 passes through the first sliding hole 1011 and extends to the inside of the separation tank 101, and the lower end of the elastic spiral piece 302 at the end of the driving arm 213 is fixedly connected, and a first adjusting screw 204 is rotatably connected to the inner wall of the first lifting hole 202, and the top of the first adjusting screw 204 passes through the first adjusting frame 201 and extends above it, and the end of the first adjusting screw 204 passes through the first slider 203 and is threadedly connected to it.

[0041] The compression adjustment assembly also includes two fixed blocks 206, the ends of the fixed blocks 206 are fixedly connected to the outer wall of the separation tank 101, a second adjusting screw 207 is rotatably connected between the two fixed blocks 206, the outer wall of the second adjusting screw 207 is threadedly connected to a connecting block 208, and the connecting block 208 is fixedly connected to the first adjustment frame 201.

[0042] Traditional filter adjustment mechanisms are mostly built into the tank body, which is susceptible to liquid corrosion and inconvenient to operate. In the above structure of the present device, the adjustment mechanism is placed outside the tank body to avoid contact with the fermentation liquid, thereby extending the service life of the screw and the connecting arm.

[0043] In some embodiments, Figure 7As shown, the outer peripheral arms of the elastic spiral filter 301 and the elastic spiral sheet 302 are fixedly connected with the outer ring spiral baffle 303, and the outer peripheral arms of the elastic spiral filter 301 and the elastic spiral sheet 302 are fixedly connected with the inner ring spiral baffle 304. The outer ring spiral baffle 303 and the inner ring spiral baffle 304 are both sleeved on the outer periphery of the positioning tube 401.

[0044] The traditional spiral filter lacks a guiding structure, and the liquid is easy to leak from the edge. In the above structure of the present device, the outer ring spiral baffle 303 forms a spiral guide wall, which forces the liquid to flow along the spiral path of the filter 301, avoiding the edge flow phenomenon of the traditional open filter and preventing liquid leakage. The inner spiral baffle 304 is in sliding contact with the positioning cylinder 401, and serves as a transmission rack of the cleaning component 4 and also plays a role in radial positioning of the filter screen to prevent the filter screen from eccentric shaking.

[0045] In some embodiments, Figure 8-Figure 10 As shown, a plurality of mounting holes 402 are provided on the outer wall of the positioning cylinder 401, wherein the bottoms of two mounting holes 402 are higher than the bottoms of the other two mounting holes 402, mounting grooves 403 are provided on both sides of the inner walls of the mounting holes 402, and sliding rods 404 are fixedly connected to the inner walls of the mounting grooves 403 on both sides of the two mounting holes 402, and springs 405 are sleeved on the outer walls of the sliding rods 404 on both sides of the two mounting holes 402, and guide rods 406 are fixedly connected to the inner walls of the mounting grooves 403 on both sides of the other two mounting holes 402; The inner wall of the mounting hole 402 is slidably connected with a support block 407, and the two sides of the support block 407 are fixedly connected with a second slider 408, one end of the spring 405 abuts against the second slider 408, and the other end of the spring 405 abuts against the inner wall of the positioning cylinder 401, and the ends of the slide rod 404 and the guide rod 406 respectively penetrate the corresponding support blocks 407 and are slidably connected thereto, and a rotating shaft 409 is rotatably connected between the two support blocks 407 at the same height, and the outer ends of the rotating shaft 409 are fixedly connected with a cleaning roller 411; The outer wall of the rotating shaft 409 is fixedly connected with a cylindrical gear 410, and the top of the inner ring spiral baffle 304 is fixedly connected with a spiral bevel rack 305, and the cylindrical gear 410 is meshed with the spiral bevel rack 305; the tooth inclination angle of the cylindrical gear 410 matches the helix angle of the spiral bevel rack 305, and the module and pressure angle of the cylindrical gear 410 and the spiral bevel rack 305 are the same, ensuring the continuity of the contact line when the teeth are meshing, and the lead of the spiral bevel rack 305 (the axial movement distance of one spiral line) matches the rotation speed of the cylindrical gear 410.

[0046] The cleaning component 4 also includes a driving mechanism, which is used to drive the positioning cylinder 401 to rotate. The driving mechanism includes a motor fixedly mounted on the outer wall of the separation tank 101, a worm fixedly mounted on the output end of the motor, and a worm wheel meshing with the worm. The end of the worm is rotatably connected to the inner wall of the positioning cylinder 401, and the worm wheel is fixedly mounted on the bottom end of the positioning cylinder 401.

[0047] The motor drives the worm to rotate, and the worm drives the worm wheel to rotate, thereby driving the positioning cylinder 401 to rotate.

[0048] The double limiting of the sliding rod 404 and the guide rod 406 can ensure the accurate axial movement trajectory of the cleaning roller 411.

[0049] Working principle: The fermentation liquid is introduced into the separation tank 101 through one end of the liquid inlet pipe 103, and the fermentation liquid flows into the elastic spiral filter 301 along the liquid guide hole 413 on the top of the partition plate 412, and the fermentation liquid flows downward along the elastic spiral filter 301, and the impurities in the fermentation liquid are filtered through the filter holes on the elastic spiral filter 301, and the filtered fermentation liquid drips onto the polyester filter cloth on the top of the elastic spiral plate 302, and the impurities in the fermentation liquid are filtered again; By rotating the third adjusting screw 212, the second connecting arm 211 slides upward along the inner wall of the second adjusting frame 209, and the second connecting arm 211 drives the elastic spiral filter 301 to move along the axis, and the distance between adjacent spiral layers of the elastic spiral filter 301 is adjusted. By adjusting the distance between the spiral layers, the inclination angle of the spiral line of the elastic spiral filter 301 relative to the axis can be changed, thereby adjusting the flow speed of the fermented liquid and controlling the speed of the first filtration of the fermented liquid; By rotating the first adjusting screw 204, the first slider 203 drives the driving arm 213 to move, and the distance between adjacent spiral layers of the elastic spiral sheet 302 is adjusted, so that the inclination angle formed by the elastic spiral sheet 302 and the polyester filter cloth spiral line relative to the axis can be independently controlled, thereby adjusting the speed of secondary filtration of the fermentation liquid; By rotating the second adjusting screw 207, the connecting block 208 drives the first adjusting frame 201 to move, and drives the elastic spiral sheet 302 to move as a whole, so as to adjust the distance between the elastic spiral sheet 302 and the spiral layer of the elastic spiral filter 301; During the cleaning process, the cleaning liquid is injected into the separation tank 101 through the other end of the liquid inlet pipe 103, the second connecting arm 211 is moved to the bottom of the inner wall of the second lifting hole 210, and the driving arm 213 is moved to the bottom of the inner wall of the first lifting hole 202. The positioning cylinder 401 is driven to rotate by the driving component, and the rotating shaft 409 is driven to rotate by the positioning cylinder 401. The rotating shaft 409 drives the cylindrical gear 410 to mesh and roll along the spiral bevel rack 305. At this time, the rotating shaft 409 drives the cleaning roller 411 to rotate, and is subjected to the spiral extrusion of the inner ring spiral baffle 304. The rotating shaft 409 drives the support block 407 to slide upward along the mounting hole 402, and the support block 407 drives the second slider 408 to slide along the outer wall of the slide rod 404, thereby cleaning the filter holes on the polyester filter cloth and the elastic spiral filter screen 301, and quickly flushing them with the cleaning liquid.
