[0033] The present utility model provides a soya bean product residue and slurry separation device for filtering solid substances (soya bean dregs) in soya bean milk during the processing of soya bean products.

[0034] In the embodiments of the present utility model, as Figures 1 to 7 shown, the soya bean product residue and slurry separation device includes a mounting frame 10, a filtering device 30, and a cleaning and screening device. An electric control device is provided on the mounting frame 10. The filtering device 30 includes a filtering container 31 and a filter net 32. The filtering container 31 is provided with a feed inlet 315, a slurry discharge port 316, and a solid outlet 314. The filter net 32 is installed inside the filtering container 31 and is located below the feed inlet 315. The solid outlet 314 is provided on the side wall of the filtering container 31 and at least partially above the filter net 32. The slurry discharge port 316 is located below the filter net 32. The cleaning and screening device includes a water pump, a slurry container 44, and a flushing nozzle 43. The slurry container 44 is communicated with the slurry discharge port 316 for receiving the slurry discharged from the slurry discharge port 316. The water pump is electrically connected to the electric control device. The water inlet end of the water pump is communicated with the slurry container 44, and the water outlet end of the water pump is communicated with the flushing nozzle 43. The flushing nozzle 43 is spaced above the filter net 32 and is arranged facing the filter net 32.

[0035] Specifically, the electric control device includes a circuit board and a controller disposed on the circuit board, etc. During use, the soy milk containing soybean dregs (solid matter) obtained from the previous process enters the filtering container 31 from the feed port 315. Among them, the slurry passes through the filter screen 32 and is discharged from the slurry discharge port 316, and flows into the slurry container 44. The soybean dregs are blocked by the filter screen 32 and remain above the filter screen 32. When the soybean dregs on the filter screen 32 increase and block the filter screen 32, the water pump can be started, and the filtered soy milk in the slurry container 44 is used to flush the filter screen 32, so as to flush the soybean dregs on the filter screen 32 to the surroundings and the solid outlet 314, reducing the blockage of the filter screen 32 by the soybean dregs. Among them, the water pump can be controlled by the electric control device to be turned on regularly. When performing screen cleaning, the delivery of soy milk to the filtering container 31 can be blocked (for example, by closing the soy milk delivery pipeline between the equipment of the previous process and the filtering container 31), and then turned on after the screen cleaning is completed. Of course, it is also possible to continuously supply soy milk from the feed port 315 to the filtering container 31 during screen cleaning.

[0036] Optionally, the mounting frame 10 includes a base 11 and a support frame 12 disposed on the base 11. The filtering device 30 is disposed above the base 11. The mounting frame 10 is located on one side of the filtering device 30, and the flushing nozzle 43 is installed on the support frame 12.

[0037] The soybean product residue and slurry separation device of the technical solution of the present utility model includes a filtering device 30 and a screen cleaning device. The filtering device 30 includes a filtering container 31 and a filter screen 32. The screen cleaning device includes a water pump, a slurry container 44 and a flushing nozzle 43. By providing a feed port 315, a slurry discharge port 316 and a solid outlet 314 in the filtering container 31, the filter screen 32 is installed in the filtering container 31 and is located below the feed port 315. At least a part of the solid outlet 314 is located above the filter screen 32, and the slurry discharge port 316 is located below the filter screen 32. Then, the slurry container 44 is communicated with the slurry discharge port 316, the water inlet end of the water pump is communicated with the slurry container 44, and the water outlet end of the water pump is communicated with the flushing nozzle 43, so that the flushing nozzle 43 is spaced above the filter screen 32 and is arranged facing the filter screen 32. In this way, the soybean dregs in the soy milk can be filtered by the filter screen 32, so that the soybean dregs are blocked on the filter screen 32, and the filtered slurry is discharged to the slurry container 44, and the slurry filtered by the filtering device 30 is collected through the slurry container 44. Thus, when the filter screen 32 is blocked by the soybean dregs, the filter screen 32 can be flushed by the water pump and the flushing nozzle 43 using the slurry in the slurry container 44, and the soybean dregs on the filter screen 32 are flushed to the surroundings and the solid outlet 314, reducing the blockage of the filter screen 32 by the soybean dregs, realizing automatic screen cleaning, reducing the situation of manual screen cleaning, and thus improving the residue and slurry filtering efficiency.

[0038] In some embodiments, the cleaning and screening device further includes a hose 46. One end of the hose 46 is connected to the water outlet end of the water pump, and the other end is connected to the flushing nozzle 43. Connecting the flushing nozzle 43 and the water pump through the hose 46 can facilitate the arrangement of the hose 46 and is beneficial to improving the structural compactness of the soy product residue slurry separation device. Of course, in other embodiments, the flushing nozzle 43 and the water pump can also be connected through a rigid pipe (stainless steel pipe or rigid plastic pipe).

[0039] In some embodiments, the flushing nozzle 43 is detachably mounted on the mounting frame 10. With this arrangement, maintenance personnel can remove the flushing nozzle 43 to manually flush the filter screen 32. That is, after the maintenance personnel arrive at the site, the machine can be inspected. If it is found that the filter screen 32 is blocked after inspection, the flushing nozzle 43 can be removed and aimed at the blocked position for flushing to wash the soybeans on the filter screen 32 towards the discharge channel 313.

[0040] In some embodiments, the cleaning and screening device further includes a driving mechanism. The driving mechanism is mounted on the mounting frame 10 and is electrically connected to the electronic control device. The flushing nozzle 43 is mounted on the driving mechanism to drive the flushing nozzle 43 to move in the horizontal direction through the driving mechanism.

[0041] By arranging the driving mechanism to drive the flushing nozzle 43 to horizontally move above the filter screen 32, the flushing range of the flushing nozzle 43 on the filter screen 32 can be increased, and the soybeans on the filter screen 32 can be better flushed to the surroundings and the solid outlet 314, reducing the blockage of the filter screen 32 by the soybeans, improving the automatic flushing effect of the soybeans on the filter screen 32, reducing the situation of manual flushing, and thus improving the automation efficiency of residue slurry separation.

[0042] In some embodiments, the driving mechanism has an actuator 411. The actuator 411 is slidably mounted on the mounting frame 10, and the flushing nozzle 43 is mounted on the actuator 411. That is, the driving mechanism drives the flushing nozzle 43 to reciprocate through the linear reciprocating motion of the actuator 411. Such a structure is simple and is beneficial to ensuring the structural reliability. Optionally, the flushing nozzle 43 adopts a fan-shaped nozzle to increase the flushing range.

[0043] In some embodiments, the flushing nozzle 43 is detachably mounted on the actuator 411. This can facilitate the staff to disassemble and wash the flushing nozzle 43 to manually flush the filter screen 32.

[0044] In some embodiments, the driving mechanism includes a driving motor 413 and a crank rocker mechanism 414. The driving motor 413 is mounted on the mounting bracket 10. The crank end of the crank rocker mechanism 414 is mounted on the rotating shaft of the driving motor 413, and the rocker end of the crank rocker mechanism 414 is hinged to the actuator 411. Such a structure is simple and reliable. While reducing costs, it can have a longer service life. Of course, in other embodiments, the flushing nozzle 43 can also be driven to rotate circumferentially along the filter screen 32 through a gear set.

[0045] In some embodiments, one end of the actuator 411 (the end far from the driving motor 413) is provided with a bayonet 412, and the flushing nozzle 43 is snap-fitted into the bayonet 412, so that the flushing nozzle 43 can be easily disassembled.

[0046] In some embodiments, the self-cleaning solid-liquid separator further includes a protective cover 60, and the protective cover 60 covers the driving motor 413 and the crank rocker mechanism 414. This can protect the driving motor 413 and the crank rocker mechanism 414 and reduce the risk of damage to the driving motor 413 and the crank rocker mechanism 414.

[0047] In some embodiments, a guide plate 70 is provided on the mounting bracket 10. The guide plate 70 is spaced above the actuator 411. The guide plate 70 is provided with a guide groove, and the guide groove extends along the movement direction of the actuator 411 and penetrates through the end of the guide plate 70 far from the driving motor 413. The flushing nozzle 43 is slidably mounted in the guide groove. With such a setting, it is not only convenient to disassemble the flushing nozzle 43, but also can guide and limit the flushing nozzle 43 to ensure the stable movement of the flushing nozzle 43.

[0048] In some embodiments, the filter screen 32 is spaced between the feed inlet 315 and the bottom wall of the filter container 31 to divide the inner cavity of the filter container 31 into a filtering chamber 311 and a liquid discharge chamber 312. The filtering chamber 311 is located above the filter screen 32, and the liquid discharge chamber 312 is located below the filter screen 32. A slurry discharge port 316 is provided on the chamber wall of the liquid discharge chamber 312. Of course, in other embodiments, the bottom of the filter container 31 is provided with an open mouth 331 to form the slurry discharge port 316.

[0049] In some embodiments, the bottom wall of the liquid discharge chamber 312 is gradually inclined downward in the direction close to the slurry discharge port 316, so that the slurry in the liquid discharge chamber 312 can fully flow out from the slurry discharge port 316 and avoid liquid accumulation in the liquid discharge chamber 312.

[0050] In some embodiments, a liquid discharge channel 33 is provided outside the filtering container 31. One end of the liquid discharge channel 33 communicates with the pulp discharge port 316, and the other end is provided with an open end 331. The flushing nozzle 43 is detachably mounted on the driving mechanism. The radial dimension of the flushing nozzle 43 is smaller than the dimension of the liquid discharge channel 33, so that it can extend into the liquid discharge cavity 312 through the liquid discharge channel 33 to wash the filter net 32. That is, when the filter net 32 is severely blocked and needs to be manually cleared, the flushing nozzle 43 can be removed from the driving mechanism, and the flushing nozzle 43 can be inserted into the liquid discharge cavity 312 through the liquid discharge channel 33, and then the filter net 32 can be washed from below the filter net 32. In this way, the flushing effect of the filter net 32 can be improved, and it can effectively prevent the soybean dregs from getting stuck in the mesh holes of the filter net 32.

[0051] In some embodiments, the soybean product residue and pulp separation device further includes a recovery container 51. The recovery container 51 is provided with a collection inlet 511 and a drainage channel 512. The collection inlet 511 communicates with the solid outlet 314. A filter element 52 is provided in the recovery container 51. The filter element 52 is arranged between the collection inlet 511 and the drainage channel 512 to prevent the soybean dregs in the recovery container 51 from being discharged to the drainage channel 512. In this way, while collecting the soybean dregs, the soybean dregs can be drained to avoid liquid accumulation in the recovery container 51. Among them, when the recovery container 51 communicates with the solid outlet 314 through the collection inlet 511, a pipeline can be provided at the solid outlet 314 and the pipeline can extend into the recovery container 51; or a discharge channel 313 communicating with the solid outlet 314 can be provided outside the filtering container 31, and the discharge channel 313 is spaced directly above the collection inlet 511. In some embodiments, the collection inlet 511 is provided with an open end 331.

[0052] In some embodiments, a flow sensor 80 is provided in the drainage channel 512. The flow sensor 80 is used to detect the liquid flow rate flowing out from the solid outlet 314 to the recovery container 51 and then flowing out from the drainage channel 512. The electronic control device is configured to start the water pump when the flow sensor 80 detects that the liquid flow rate reaches a preset value.

[0053] Specifically, when the filter net 32 is blocked by soybean dregs, it will cause the liquid to flow towards the solid outlet 314 and then towards the drainage channel 512 of the recovery container 51. By providing the flow sensor 80 in the drainage channel 512, when the flow sensor 80 detects that the liquid flow rate reaches the preset value, it can be determined that the filter net 32 is blocked. At this time, the flow sensor 80 sends an electrical signal to the electronic control device. After receiving the electrical signal sent by the flow sensor 80, the electronic control device controls the water pump to work, so as to wash the filter net 32 through the flushing nozzle 43, and wash the soybean dregs on the filter net 32 to the surrounding and the solid outlet 314, reducing the blockage of the filter net 32 by the soybean dregs. In this way, it can be detected in time when the filter net 32 is blocked, and the water pump can be automatically started for screen cleaning, which is beneficial to improving the filtration efficiency.

[0054] In some embodiments, the bottom wall of the recovery container 51 gradually slopes downward in the direction close to the drainage channel 512, so that the drainage channel 512 is at the lowest position of the recovery container 51, which can avoid liquid accumulation in the recovery container 51 and also make the liquid flow to the drainage passage faster, so that the flow sensor 80 can detect the liquid overflowing from the solid outlet 314 in time.

[0055] In some embodiments, the upper surface of the filter screen 32 is horizontally arranged, which can reduce the possibility of the slurry entering the solid outlet 314. In other embodiments, the upper surface of the filter screen 32 gradually slopes downward in the direction close to the solid outlet 314, which can facilitate flushing the bean dregs towards the solid outlet 314.

[0056] In some embodiments, the sieve-passing device further includes a vibration motor and a vibration mechanism 45 connected to the vibration motor. The vibration motor is installed on the mounting frame 10 and is electrically connected to the electric control device. The vibration mechanism 45 is installed at the bottom of the filter container 31. In this way, the vibration motor can drive the vibration mechanism 45 to vibrate, thereby driving the filter container 31 and the filter screen 32 inside the filter container 31 to vibrate. During the process of driving the filter screen 32 to vibrate, the bean dregs on the filter screen 32 can be made to shake, thereby preventing the bean dregs from blocking the mesh holes of the filter screen 32 and enabling at least part of the bean dregs to move to the solid outlet 314, so that sieve passing can be realized. Among them, the vibration motor can be always turned on during the filtering process (that is, the vibration motor is started at the beginning of the filtering work, which can reduce the possibility of the filter screen 32 being blocked and also improve the filtering efficiency), or the vibration motor can be set to be turned on regularly; the electric control device can also be set to start the vibration motor when the flow sensor 80 detects that the liquid flow reaches a preset value.

[0057] Optionally, the vibration mechanism 45 includes a mounting seat 451, an eccentric mechanism 453 and a plurality of springs 452. The mounting seat 451 is mounted on the base 11 (mounting frame 10), and the plurality of springs 452 are connected between the filter container 31 and the mounting seat 451 to support the filter container 31 above the mounting seat 451. The eccentric mechanism 453 is mounted at the bottom of the filter container 31 and is connected to the vibration motor. When the vibration motor drives the eccentric block of the eccentric mechanism 453 to move, the filter container 31 is driven to vibrate.

[0058] In some embodiments, the vibration motor and the water pump can be started simultaneously for sieve cleaning to improve the sieve cleaning effect.

[0059] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
