Description

Technical Field

[0001] The invention belongs to the technical field of bean product processing, and in particular relates to a device for quickly separating soy milk and bean dregs used in the production of soy food. Background Art

[0002] Soy milk is a beverage made from soybeans. Soybeans are crushed into fine pulp by a soybean milk machine, and then filtered through a filter to obtain soybean milk after the dregs are separated. The existing commercial equipment for making soybean milk is a pulp-residue separator, which generally uses a centrifugal filtration method to separate the pulp and residue. A trumpet-shaped filter device with an opening at the top is driven by a motor to rotate. After the pulp-like raw materials fall into the filter device, they will be thrown toward the side wall of the filter device under the action of centrifugal force. The dregs will be blocked and the soybean milk will pass through the filter device and flow out from the pulp outlet pipe. Although a part of the dregs in the filter device will slide upward along the side wall of the filter device under the action of centrifugal force and be discharged from the dregs outlet, another part will adhere to the inner wall of the filter device under the action of centrifugal force, which will cause the filtering capacity of the filter device to decrease and the continuous production capacity to be insufficient. Moreover, the machine head needs to be disassembled and cleaned after use, and maintenance is relatively troublesome. The centrifugal filter device also has the problem of insufficient filtering capacity and cannot completely filter the soybean milk in the dregs, which will cause material waste.

[0042] The slag discharge mechanism includes a slag bucket 14, a slag pushing cone 11, a spiral strip 12, an extrusion tube 15, an extrusion screw 13, a transmission shaft 23, a connecting rod 24 and a scraper 25.

[0043] The filter press mechanism includes a reflux pipe 8, a filter press tube 17, a mounting frame 19, a pressing plate 20, a guide rod 21 and a spring 22. The reflux pipe 8 is arranged on the housing 1 and connected to the housing 1 through a thread. The filter press tube 17 is located in the reflux pipe 8, and the input end of the filter press tube 17 is connected to the extrusion tube 15 through a thread, and the output end is aligned with the free end of the reflux pipe 8. The mounting frame 19 is installed on the outside of the output end of the filter press tube 17 by bolts, and the guide rod 21 is slidably arranged on the mounting frame 19. The pressing plate 20 is fixed to one end of the guide rod 21. When the pressing plate 20 is in contact with the output end of the filter press tube 17, the output end of the filter press tube 17 will be completely covered. The spring 22 is sleeved on the guide rod 21 between the pressing plate 20 and the mounting frame 19. A plurality of liquid outlet grooves 18 are also arranged on the side wall of the filter press tube 17 located in the reflux pipe 8.

[0044] The transmission mechanism includes a transmission box 5 and a drive motor 7. The drive motor 7 is fixed on the transmission box 5, and the output end extends into the transmission box 5 and is fixedly provided with a main drive gear 35. The transmission box 5 is also provided with a main driven gear 343, a drive gear set 34 and a transmission gear set 33. The main driven gear 343 is transmission-connected with the drive gear set 34, and the main drive gear 35 is meshed with the main driven gear 343. The drive gear set 34 is transmission-connected with the transmission gear set 33. The transmission gear set 33 includes a discharge transmission gear 331 and a grinding disc transmission gear 332. In this embodiment, it also includes an auger transmission gear 333, and the discharge transmission gear 331, the grinding disc transmission gear 332 and the auger transmission gear The wheels 333 are all double-layer gears, and the driving gear sets 34 are respectively connected to the main driving gear 35 and the transmission gear set 33. In this embodiment, there are two driving gear sets 34, one is a high-speed gear set 341, and the other is a high-speed gear set 341. The high-speed gear set 341 includes a discharge high-speed gear 3411, a grinding disc high-speed gear 3412 and an auger high-speed gear 3413, and the low-speed gear set 342 includes a discharge low-speed gear 3421, a grinding disc low-speed gear 3422 and an auger low-speed gear 3423. The various gears in the high-speed gear set 341 and the various gears on the low-speed gear set 342 are respectively connected through the installation shaft 344, and the main and driven gears 343 are also connected to the installation.

[0045] The transmission mechanism also includes a switching assembly, through which the driving gear is installed in the transmission box 5, and the switching assembly is used to control the engagement and disengagement of the high-speed gear set 341 or the low-speed gear set 342 with the main driving gear 35 and the transmission gear set 33.

[0046] Since the output power of the driving motor 7 remains unchanged, if the output speed of the device is increased, the torque will decrease, and conversely, if the output speed of the device is reduced, the torque will increase.

[0047] Generally, the beans are soaked in water before making soy milk. The soaked beans will become soft. At this time, the torque required for the grinding disc to crush the beans is relatively small, so the high-speed gear set 341 can be selected by switching the components to mesh with the main drive gear 35 and the transmission gear set 33. At this time, the rotation speed of the equipment will be relatively high, which can improve the efficiency of making soy milk.

[0048] If the beans for making soy milk are not soaked in water in advance, the beans will be relatively hard. At this time, the torque required for the grinding disc to crush the beans will become larger, so it is necessary to separate the high-speed gear set 341 from the main drive gear 35 and the transmission gear set 33 through a switching component, and then mesh the low-speed gear set 342 with the main drive gear 35 and the transmission gear set 33. At this time, the rotation speed of the equipment will be reduced, ensuring the grinding disc's crushing effect on the beans.

[0049] The switching assembly includes an adjusting ring 6, an annular groove 45, a lead screw 37, a slider 29, a driven helical gear 38, a synchronous shaft 40, a driving helical gear 41 and a driving spur gear 42. The annular groove 45 is arranged on the outer wall of the transmission box 5 and is also provided with an identification line. A limiting groove 46 is arranged on the side wall of the annular groove 45. The adjusting ring 6 is sleeved on the transmission box 5, and is provided on both the adjusting ring 6 and the transmission box 5. An adjusting gear ring 43 and a limiting block 44 are arranged on the inner wall of the adjusting ring 6, and the limiting block 44 is located in the limiting groove 46; the lead screw 37 and the synchronous shaft 40 are both located in the transmission box 5, and the lead screw 37 is two and passes through the first A fixing frame 36 is rotatably set on a set of opposite inner walls of the transmission box 5, the slider 29 is matched and installed on the screw 37, the high-speed gear set 341 and the low-speed gear set 342 are rotatably connected with the slider 29 through the mounting shaft 344, the driven helical gear 38 is fixed to one end of the screw 37, the synchronous shaft 40 is rotatably set on the inner wall of the transmission box 5 through the second fixing frame 39, the driving helical gear 41 is fixed to both ends of the synchronous shaft 40 and meshes with the driven helical gear 38, the driving spur gear 42 is fixedly sleeved on the synchronous shaft 40, and passes through the side wall of the transmission box 5 to mesh with the adjusting gear ring 43.

[0050] The grinding disc assembly includes a ring plate 2, a feed hopper 3, a fixed grinding disc 26 and a movable grinding disc 27. The fixed grinding disc 26 is a circular ring. A conical material guide structure is provided on the movable grinding disc 27. After the soybeans enter from the middle of the fixed grinding disc 26, they will enter between the fixed grinding disc 26 and the movable grinding disc 27 from the four sides of the conical material guide structure under the guidance of the conical material guide structure. The ring plate 2 is fixedly arranged in the shell 1, and the bottom is connected to the filter cartridge 28. The feed hopper 3 is arranged on the top of the ring plate 2, and the output end is connected to the center hole of the ring plate 2. The fixed grinding disc 26 matches the movable grinding disc 27 and both are located below the ring plate 2. The fixed grinding disc 26 is fixedly connected to the ring plate 2. A rotating tube 31 is fixedly arranged on the movable grinding disc 27, and the free end of the rotating tube 31 is connected to the output end of the transmission mechanism.

[0051] In one embodiment, a feeding auger 30 is rotatably mounted on the rotating tube 31. One end of the feeding auger 30 is connected to the transmission mechanism, and the other end is located above the movable grinding disc 27. The rotation of the auger can push the soybeans toward the grinding disc.

[0052] The bottom of the shell 1 is also provided with a slag discharge hole 32, which is connected to the squeeze tube 15. A sealing plug 16 is installed on the slag discharge hole 32 through a thread. After use, the bean dregs need to be cleaned. At this time, the bean dregs are concentrated in the squeeze tube 15 and the filter press tube 17. Before cleaning the bean dregs in the filter press tube 17, the return pipe 8 needs to be removed from the shell 1, and then the pressure pipe is removed from the squeeze tube 15. When cleaning, the end of the filter press tube 17 of the mounting frame 19 is inserted. At this time, the two ends of the filter press tube 17 are connected. The bean dregs in the filter press tube 17 can be pushed out by inserting a tool from one side, and then the filter press tube 17 can be cleaned and reinstalled for reuse; when cleaning the bean dregs in the squeeze tube 15, the sealing plug 16 needs to be removed first, and the bean dregs in the squeeze tube 15 can be taken out by a tool, and then water is poured into the equipment through the guide trough 4 to rinse, and the filter press tube 17, the return pipe 8 and the sealing plug 16 are reinstalled after all the bean dregs are rinsed.

[0053] The shell 1 is also provided with a material guide trough 4, a slurry discharge pipe 9 and a plurality of support legs 10. The plurality of support legs 10 are evenly fixed at the bottom of the shell 1 around the circumference of the shell 1. The slurry discharge pipe 9 is fixed at the lower part of the side wall of the shell 1 and is connected to the inside of the shell 1. The material guide trough 4 is fixed at the upper part of the side wall of the shell 1 and is connected to the feed hopper 3.

[0054] The working process of this embodiment is as follows: when in use, soybeans are poured into the guide trough 4, and the soybeans will slide into the feed hopper 3 along the guide trough 4. The feed hopper 3 is trumpet-shaped. Guided by the trumpet-shaped feed hopper 3, the soybeans will enter between the fixed grinding disc 26 and the movable grinding disc 27 from the hole in the middle of the fixed grinding disc 26.

[0055] Then select the matching output speed according to the state of soybeans;

[0056] If the equipment needs to output at a high speed, it is necessary to move the adjusting ring 6 upward so that the limit block 44 of the adjusting ring 6 moves out of the limit groove 46 and into the ring groove 45, and then rotate the adjusting ring 6 to drive the meshing driving spur gear 42 to rotate through the adjusting gear ring 43 on the inner side of the adjusting ring 6. After the driving spur gear 42 rotates, it will drive the synchronous shaft 40 to rotate. After the synchronous shaft 40 rotates, it will drive the meshing driven helical gear 38 to rotate through the driving bevel gears 41 at both ends. After the driven bevel gear 38 rotates, both lead screws 37 will rotate. Since the sliders 29 on the two lead screws 37 are connected to the mounting shaft 344, the slider 29 cannot rotate when the lead screw 37 rotates, so the slider 29 will move along the axis of the lead screw 37 under the push of the lead screw 37.

[0057] like Figure 6As shown, at this time, the low-speed gear set 342 is installed on the switching component on the left, and the high-speed gear set 341 is installed on the switching component on the right, and the thread directions of the threads on the four lead screws 37 are the same, so after rotating the adjusting ring 6, the low-speed gear set 342 on the left will move to the left driven by the slider 29, and the connection with the transmission gear set 33 will be disconnected, while the high-speed gear set 341 on the right will also move to the left driven by the slider 29 and be connected to the transmission gear set 33, that is, the discharge high-speed gear 3411 in the high-speed gear set 341 will be connected to the discharge transmission gear in the transmission gear set 33. The wheel 331 is meshed, the grinding disc high-speed gear 3412 in the high-speed gear set 341 is meshed with the grinding disc transmission gear 332 in the transmission gear set 33, the auger high-speed gear 3413 in the high-speed gear set 341 is meshed with the auger transmission gear 333 in the transmission gear set 33, and the master driven gear 343 connected to the mounting shaft 344 of the high-speed gear set 341 is meshed with the master drive gear 35 at the output end of the drive motor 7. At this time, the adjusting ring 6 will be aligned with the marking line on the transmission box 5 after rotation, and then the adjusting ring 6 needs to be moved downward so that the limit block 44 is stuck in the limit groove 46 again.

[0058] If the device needs to be adjusted from high speed output to low speed output, the adjusting ring 6 is moved upward again and then rotated in the opposite direction. When the marking line on the adjusting ring 6 is aligned with the marking line on the transmission box 5 again, the adjustment is completed.

[0059] After the adjusting ring 6 is rotated in the opposite direction, the lead screw 37 will drive the slider 29 to move to the right, the high-speed gear set 341 will be disconnected from the transmission gear set 33, and the discharging low-speed gear 3421 in the low-speed gear set 342 will mesh with the discharging transmission gear 331 in the transmission gear set 33, the grinding disc low-speed gear 3422 in the low-speed gear set 342 will mesh with the grinding disc transmission gear 332 in the transmission gear set 33, the auger low-speed gear 3423 in the low-speed gear set 342 will mesh with the auger transmission gear 333 in the transmission gear set 33, and the main driven gear 343 connected to the mounting shaft 344 of the low-speed gear set 342 will mesh with the main driving gear 35 at the output end of the driving motor 7.

[0060] When the low-speed gear set 342 or the high-speed gear set 341 is connected to the transmission gear set 33, the driving motor 7 rotates to drive the auger, the moving grinding disc 27, the slag pusher 11 and the scraper 25 to rotate.

[0061] The auger will push the soybeans in the feed hopper 3 toward between the dynamic grinding disc 27 and the fixed grinding disc 26. The slurry crushed by the dynamic grinding disc 27 and the fixed grinding disc 26 will be thrown toward the filter cylinder 28 under the action of centrifugal force. A part of the soybean milk will flow out from the pulp outlet pipe 9 after passing through the filter cylinder 28, and a part of the bean dregs blocked by the inner wall of the filter cylinder 28 will fall, and a part will adhere to the inner wall of the filter cylinder 28. At this time, the scraper 25 will rotate under the drive of the transmission shaft 23 to scrape off the bean dregs attached to the inner wall of the filter cylinder 28. The fallen bean dregs will move toward the extrusion screw 13 under the push of the spiral strips 12 on the dregs pushing cone 11, and the extrusion screw 13 will continuously squeeze the bean dregs into the extrusion tube 15, and the extrusion tube 15 The capacity is limited, so part of the dregs will enter the filter press tube 17. When the dregs move to contact the baffle, they will be blocked by the baffle. At this time, the extrusion screw 13 is still squeezing the dregs into the extrusion tube 15. The volume of the dregs will be compressed, and the soy milk in the dregs will be squeezed out, flow into the reflux pipe 8 through the liquid outlet trough 18 on the filter press tube 17, and flow into the shell 1 under the guidance of the reflux pipe 8, and finally flow out from the slurry outlet pipe 9. After the soy milk in the dregs is squeezed out, the volume of the dregs will not be able to be compressed any further. When the thrust of the dregs on the pressing plate 20 is greater than the pressure applied to the pressing plate 20 by the spring 22, the dregs will push the pressing plate 20 away and move out of the filter press tube 17.

[0062] The bean dregs without soybean milk will be more scattered and will fall from the discharge end of the filter press tube 17 after the baffle is pushed open.

[0063] In this embodiment, the rotational speed is adjusted by adjusting the diameters of the driving gear and the driven gear. When the large gear drives the small gear to rotate, the rotational speed will increase, and when the small gear drives the large gear to rotate, the rotational speed will decrease. The diameter of the discharge high-speed gear 3411 is larger than the diameter of the discharge low-speed gear 3421, the diameter of the grinding disc high-speed gear 3412 is larger than the diameter of the grinding disc low-speed gear 3422, and the diameter of the auger high-speed gear 3413 is larger than the diameter of the auger low-speed gear 3423. However, the diameter of the main drive gear 35 is exactly the same as that of the main driven gear 343.

[0064] Among them, since each gear in the transmission gear set 33 is a double-layer gear, that is, a large gear and a small gear are fixedly connected together, in order to enhance the effect, when the high-speed gear set 341 is connected to the transmission gear set 33, it will mesh with the small gear; when the low-speed gear set 342 is connected to the transmission gear set 33, it will mesh with the large gear.

[0065] It should be noted that in order to make the various components in the equipment work in coordination, the rotation speed of the moving grinding disc 27 needs to be greater than the rotation speed of the feeding auger 30 and the slag pusher 11, so the diameter of the grinding disc high-speed gear 3412 is greater than the diameters of the discharge high-speed gear 3411 and the auger high-speed gear 3413; and the diameter of the grinding disc low-speed gear 3422 is greater than the diameters of the discharge high-speed gear 3411 and the auger low-speed gear 3423. And the modulus and pressure angle of each gear in this embodiment are the same.

[0066] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
