Description

Technical Field

[0001] This invention relates to the field of chemical component processing equipment technology, specifically a multi-stage filtration structure for chemical component processing. Background Technology

[0002] Food contains a wide variety of chemical components, including many nutrients. Natural foods contain proteins, fats, carbohydrates, dietary fiber, vitamins, minerals, and water, all essential nutrients for the human body. However, food contains far more than just these nutrients. For example, the processing and extraction of plant proteins requires grinding the plants using processing equipment, followed by filtering the resulting slurry to separate out impurities. However, existing filtration devices cannot adequately filter the slurry, resulting in poor filtration efficiency. Furthermore, existing filtration devices are inconvenient for disassembling and cleaning the filter screens, further impacting processing efficiency. Therefore, this application provides a multi-stage filtration structure for processing chemical components. Summary of the Invention

The bottom ends of the vertical groove and the movable rod extend to the lower side of the installation cylinder. The top extends to the upper side of the mounting cylinder. A limiting groove 1 is opened on the lower side of the end of the turntable away from the fixed axis. A limiting block is fixedly connected to the movable rod. The limiting block is slidably engaged in the limiting groove 1. A limiting groove 2 is opened in the side wall of the mounting cylinder. The limiting groove 2 is located directly below the limiting groove 1. A receiving cavity 1 is opened in the side wall of the mounting cylinder. The movable rod passes through the receiving cavity 1.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1-11 As shown, a multi-stage filtration structure for processing chemical components includes a support 1, a grinding box 2 fixedly installed at the top center of the support 1, and a grinding component 4 disposed above the interior of the grinding box 2, which is capable of grinding beans.

[0035] A filter assembly 6 is provided below the grinding assembly 4, which can perform preliminary filtration of the grinding fluid discharged from the grinding assembly 4.

[0036] A liquid collection hopper 7 is fixedly installed in the middle of the bottom of the grinding box 2, and the grinding liquid filtered by the filter assembly 6 can flow into the liquid collection hopper 7.

[0037] A hose 8 is fixedly installed at the bottom of the liquid collection hopper 7, and a collection tank 3 is fixedly installed in the middle of the bottom of the bracket 1. The lower end of the hose 8 is connected to the upper end of the collection tank 3 through the filter assembly 9.

[0038] like Figure 2 and Figure 3 As shown, the grinding assembly 4 includes a feed pipe 41, which is rotatably mounted at the top center of the grinding chamber 2 and connected to the drive assembly. The drive assembly includes a motor 43, which is fixed to the top side of the grinding chamber 2, and the output end of the motor 43 is connected to the upper part of the feed pipe 41 via a transmission belt 42.

[0039] The upper end of the feed pipe 41 extends to the outside of the grinding box 2 and is fixedly connected to the feed hopper 11. The feed hopper 11 facilitates the addition of beans into the feed pipe 41.

[0040] A movable grinding element 44 is fixedly connected to the bottom end of the feed pipe 41. When the feed pipe 41 rotates, the movable grinding element 44 rotates accordingly. A fixed grinding element 45 is fixed inside the grinding box 2 below the movable grinding element 44. The bottom of the movable grinding element 44 and the top of the fixed grinding element 45 cooperate to grind the beans.

[0041] Furthermore, a support plate 46 is fixedly connected to the bottom of the fixed grinding component 45. Both ends of the support plate 46 are fixedly connected to the inner wall of the grinding chamber 2. Patterns are provided on the opposite sidewalls of the movable grinding component 44 and the fixed grinding component 45. A first grinding chamber 48 is provided near the center of the opposite sidewalls of the movable grinding component 44 and the fixed grinding component 45. A second grinding chamber 49 is provided near the edge of the opposite sidewalls of the movable grinding component 44 and the fixed grinding component 45. The gap of the second grinding chamber 49 is smaller than the gap of the first grinding chamber 48. The beans in the feed pipe 41 first enter the first grinding chamber 48 for preliminary crushing, and then the preliminarily crushed beans enter the second grinding chamber 49 for further grinding.

[0042] A fixing post 47 is fixedly connected to the top center of the fixed grinding part 45. The fixing post 47 is located inside the lower end of the feed pipe 41, and the top of the fixing post 47 is round.

[0043] like Figure 3 and Figure 5 As shown, guide components 5 are provided on both sides of the bottom end of the feed pipe 41.

[0044] The guiding assembly 5 includes a guiding rod 54 that is dynamically sealed and installed in a mounting hole on the side wall of the feed pipe 41.

[0045] An annular water tank 53 is fixedly installed on the outside of the feed pipe 41, and the water tank 53 rotates synchronously with the feed pipe 41.

[0046] Water holes 12 are provided at the upper end of the grinding box 2 and the upper end of the water tank 53, and the water holes 12 on the upper and lower sides are set accordingly.

[0047] One end of the guide rod 54 extends into the inside of the feed pipe 41 and has a water trough 59 on its outer edge. The other end of the guide rod 54 extends into the inside of the water tank 53 and is rotatably connected to a rotating block 55. A baffle 57 is fixedly connected inside the water tank 53. A spring 56 is fixedly connected between the rotating block 55 and the baffle 57. A fixing block 58 is fixedly connected inside the water tank 53. The guide rod 54 is threadedly connected to the fixing block 58. A magnetic plate 52 is fixedly connected to the end of the guide rod 54 located inside the feed pipe 41. A magnet block 51 is fixedly installed on the bottom side of the fixing column 47.

[0048] like Figure 9 As shown, there are two sets of magnet blocks 51, which are fan-shaped and symmetrically arranged on both sides of the fixing post 47. The magnetic poles of the magnet blocks 51 and the magnetic plate 52 are the same at their opposite ends.

[0049] During the rotation of water tank 53, when magnet block 51 aligns with magnetic plate 52, the guide rod 54 moves away from fixed post 47 due to the repulsive force between them. Simultaneously, the guide rod 54 rotates due to the threaded connection between it and fixed block 58. As the guide rod 54 moves away from fixed post 47, it clears the beans in feed pipe 41. When water tank 59 is connected to water tank 53, water in water tank 53 can be discharged through water tank 59. In other words, during the rotation of water tank 53, feed pipe 41, and movable grinding element 44, the guide rod 54 intermittently clears the beans in feed pipe 41, while water in water tank 53 intermittently discharges and mixes with the crushed beans to form a slurry.

[0050] like Figure 2 , Figure 3 and Figure 6As shown, filter assembly 6 includes two rotating shafts 61, which are symmetrically mounted inside the grinding chamber 2. Grinding assembly 4 is located between the two rotating shafts 61. A mounting bracket 65 corresponding to the rotating shafts 61 is fixedly connected to the lower inner wall of the grinding chamber 2. The mounting bracket 65 is L-shaped. A helical gear 64 is fixedly connected to the rotating shafts 61. A connecting shaft 67 is rotatably mounted on the mounting bracket 65. A helical gear 66 is concentrically fixedly connected to one end of the connecting shaft 67. The helical gear 64 and the helical gear 66 mesh with each other. A cam 68 is fixedly connected to the other end of the connecting shaft 67. Two mounting plates 69 are fixedly connected to the mounting bracket 65. A slide rod 611 is fixedly connected between the two mounting plates 69. A sliding sleeve 612 is slidably connected to the slide rod 611. A connecting plate 617 is fixedly connected to the top of the sliding sleeve 612. The connecting plate 617 is located at the cam 68. Above, the outer edge of the cam 68 contacts the lower end of the connecting plate 617. A slider is fixedly connected to the end of the connecting plate 617 away from the sliding sleeve 612. The slider is slidably set in the sliding groove 618 opened on the mounting bracket 65. Spring 2 610 and spring 3 616 are sleeved on the sliding rod 611. The top end of spring 3 616 is fixedly connected to the upper mounting plate 69, and the lower end of spring 3 616 is fixedly connected to the upper end of the connecting plate 617. A mounting frame 613 is set between the two rotating shafts 61. The mounting frame 613 is fixedly connected to the sliding sleeve 612. A filter screen 1 614 is detachably fixedly installed in the mounting frame 613. A through groove 1 615 is opened in the middle of the bottom of the mounting frame 613. A liquid hopper 2 10 is fixedly connected to the bottom end of the mounting frame 613. The lower end of the liquid hopper 2 10 is open and located directly above the liquid hopper 1 7.

[0051] When the shaft 61 rotates, the cam 68 rotates due to the meshing of helical gear 64 and helical gear 66. During the rotation of the cam, the mounting frame 613 drives the filter screen 614 to move up and down reciprocally, thereby improving the filtration efficiency of the filter screen 614 for the slurry. After being filtered by the filter screen 614, the slurry enters the collection hopper 10. The slurry discharged from the lower end of the collection hopper 10 flows sequentially through the collection hopper 7 and the hose 8.

[0052] A spur gear 63 is fixedly connected to the upper part of the rotating shaft 61, and a gear ring 62 is fixedly connected to the outer wall of the movable grinding part 44. The gear ring 62 meshes with the spur gear 63. Under the meshing action of the gear ring 62 and the spur gear 63, the two rotating shafts 61 can rotate simultaneously.

[0053] like Figure 2 , Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, filter assembly 29 is located at the top center of collection tank 3.

[0054] The filter assembly 29 includes a limiting cylinder 91 fixedly installed in the middle of the top of the collection tank 3. The limiting cylinder 91 has an inner cavity 92 that runs vertically through the middle. An installation cylinder 94 is movably installed in the inner cavity 92. The bottom end of the hose 8 is fixedly inserted into the top of the installation cylinder 94.

[0055] A lifting block 95 is fixedly connected to the top side of the mounting cylinder 94.

[0056] The lower part of the mounting cylinder 94 is provided with movable grooves 96 at intervals. A fixed shaft 97 is fixedly connected to one side of the movable groove 96. A turntable 98 is movably and sealed in the movable groove 96. One side of the turntable 98 is rotatably connected to the fixed shaft 97.

[0057] A vertical groove 912 is provided on the side of the mounting cylinder 94 away from the fixed shaft 97. A movable rod 913 is movably mounted in the vertical groove 912. The bottom ends of the vertical groove 912 and the movable rod 913 extend to the lower side of the mounting cylinder 94, and the top end of the movable rod 913 extends to the upper side of the mounting cylinder 94. A limiting groove 916 is provided on the lower side of the end of the turntable 98 away from the fixed shaft 97. A limiting block 917 is fixedly connected to the movable rod 913, and the limiting block 917 is slidably engaged in the limiting groove 916.

[0058] The mounting cylinder 94 has a second limiting groove 918 inside its side wall, which is located directly below the first limiting groove 916. The mounting cylinder 94 also has a first receiving cavity 914 inside its side wall, through which the movable rod 913 passes. A fourth spring 915 is installed in the first receiving cavity 914 to allow the movable rod 913 to return to its original position after descending. The top center of the turntable 98 has a mounting groove 99. A second filter screen 910 is installed in the mounting groove 99 of the upper turntable 98, and a third filter screen 911 is installed in the mounting groove 99 of the lower turntable 98. The lower end of the turntable 98 has a second through groove 93 that communicates with the mounting groove 99.

[0059] The pore size of filter screen 2 (910) is larger than that of filter screen 3 (911).

[0060] The slurry that enters the installation cylinder 94 through the hose 8 can be filtered sequentially by filter screen 2 910 and filter screen 3 911. The slurry filtered by filter screen 2 910 and filter screen 3 911 enters the collection tank 3.

[0061] Furthermore, a second receiving cavity 920 is formed in the side wall of the mounting cylinder 94 away from the fixed shaft 97. The two ends of the second receiving cavity 920 are connected to the inner cavity 92 and the vertical groove 912, respectively. A limit rod 923 is slidably installed in the second receiving cavity 920. A conical groove 919 is formed on the outer edge of the movable rod 913. A blind hole 924 corresponding to the limit rod 923 is formed on the inner wall of the limiting cylinder 91. One end of the limit rod 923 is inserted into the blind hole 924. 3 is fixedly connected to a baffle 921, which is slidably disposed in a receiving cavity 920. A spring 922 is installed in the receiving cavity 920 to reset the limiting rod 923. During the downward movement of the movable rod 913, when the conical groove 919 corresponds to the limiting rod 923, under the elastic force of the spring 922, one end of the limiting rod 923 enters into the conical groove 919, and the other end of the limiting rod 923 exits from the blind hole 924.

[0062] When cleaning filter screens 910 and 911 is required, press down on the movable rod 913. As the movable rod 913 moves downward, it drives the limiting block 917 downward. After the limiting block 917 enters the limiting groove 918, it exits from the limiting groove 916. The conical groove 919 corresponds to the limiting rod 923. Under the elastic force of the spring 922, one end of the limiting rod 923 enters the conical groove 919, and the other end exits from the blind hole 924. Then, the mounting cylinder 94 can be pulled out from the limiting cylinder 91. After the mounting cylinder 94 is pulled out from the limiting cylinder 91, the turntable 98 can rotate around the fixed shaft 97 because the limiting block 917 has exited the limiting groove 916. After the turntable 98 rotates out from its movable groove 96, it is convenient to clean filter screens 910 and 911.

[0063] In use, beans are fed into the feed pipe 41 from the feed hopper 11. After being guided by the fixed column 47, the beans gather above the first grinding chamber 48. Then, the motor 43 is started. The motor 43 drives the feed pipe 41 to rotate through the transmission belt 42, which in turn drives the movable grinding element 44 to rotate. During the rotation, the beans fall into the first grinding chamber 48. Through the relative movement of the movable grinding element 44 and the fixed grinding element 45, the beans are initially crushed. The initially crushed beans enter the second grinding chamber 49 from the first grinding chamber 48. The gap in the second grinding chamber 49 is smaller, so the beans can be ground more finely.

[0064] During the rotation of the water tank 53, the feed pipe 41 and the movable grinding part 44, the guide rod 54 can intermittently clear the beans in the feed pipe 41, and at the same time the water in the water tank 53 can be intermittently discharged to mix with the crushed beans to form a slurry.

[0065] The slurry flows down the second grinding chamber 49 into the lower filter assembly 6, where it is filtered out by the first filter screen 614 to remove larger debris. Simultaneously, the rotating grinding piece 44 drives the gear ring 62, which in turn drives the spur gear 63. The spur gear 63 then drives the rotating shaft 61, which in turn drives the lower helical gear 64. The helical gear 64 drives the second helical gear 66, which in turn drives the cam 68 via the connecting shaft 67. As the cam 68 rotates, it intermittently pushes the connecting plate 617 upwards, which in turn drives the sliding sleeve 61. 2. The upward movement causes the mounting frame 613 and filter screen 614 to move upward, compressing the spring 616. When the cam 68 rotates until it no longer pushes the connecting plate 617 upward, the rebound force of the spring 616 and the gravity of the mounting frame 613 and filter screen 614 cause the sliding sleeve 612, mounting frame 613, and filter screen 614 to move downward and touch the top of the spring 610. The spring 610 causes the mounting frame 613 and filter screen 614 to vibrate, thereby preventing the filter screen 614 from clogging and facilitating rapid filtration of the slurry.

[0066] The slurry then flows into the filter assembly 9 through the slurry collection hopper 2 10, the slurry collection hopper 1 7, and the hose 8. The slurry falls into the installation cylinder 94 and is filtered again by the filter screens 2 910 and 3 911 inside the installation cylinder 94.
