This solves the problems of existing filtration devices where sediment in the food solution easily clogs the filter element, and residues adhere to the filter element after filtration, making filter element disassembly inconvenient and affecting solid residue sampling, thus causing inconvenience to users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a food testing filter, comprising a casing, a feed hopper fixedly connected to the upper part of the casing, an internally threaded ring connected to the bottom of the feed hopper, a filter cylinder threadedly connected to the lower part of the internally threaded ring, a movable ring slidably connected to the lower part of the filter cylinder, a filter element threadedly connected to the inner part of the movable ring, a positioning ring fixedly connected to the upper part of the filter cylinder, a first compression spring fixedly connected to the bottom of the positioning ring, and the bottom end of the first compression spring fixedly connected to the top of the movable ring. Support plates are fixedly connected to the left and right sides of the rear of the inner wall of the chassis, and shafts are fixedly connected to the inner sides of the two support plates. A rocker arm is rotatably connected to the surface of the shaft arm, and a jacking head is fixedly connected to the front end of the rocker arm. A first support plate is fixedly connected to the upper part of the rear side of the inner wall of the chassis, and a second support plate is fixedly connected to the lower part of the rear side of the inner wall of the chassis.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model involves pouring the mixed food solution into a feeding hopper, which then enters the filter cylinder for filtration. During filtration, a vibration motor is activated, causing the rear end of a rocker arm to vibrate up and down. A second spring supports the rocker arm, causing it to spring back, which in turn moves the rear end of the rocker arm up and down repeatedly, causing the front end to move up and down as well. This movement of the front end of the rocker arm moves the agitator head up and down, striking the bottom of the filter element. The first spring applies downward pressure to the moving ring, causing it to vibrate inside the filter cylinder, reducing clogging. After filtration, when sampling solid residues, the filter cylinder can be held and twisted in the opposite direction to remove it from the bottom of the internal threaded ring for easy sampling. When the filter element needs replacement, it can be loosened from the moving ring. This design achieves the advantages of vibrating the filter element during filtration to prevent clogging, improving filtration efficiency, facilitating filter element removal after filtration, and improving testing effectiveness. It is also user-friendly.

[0014] 2. By setting up a coarse filter frame, the food solution can be initially filtered through the coarse filter frame and coarse filter screen after being poured into the feed hopper.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, the present invention provides a food testing filter, comprising a housing 1, a feed hopper 2 fixedly connected to the upper part of the housing 1, an internal threaded ring 3 connected to the bottom of the feed hopper 2, a filter cylinder 4 threadedly connected to the lower part of the internal threaded ring 3, a movable ring 5 slidably connected to the lower part of the filter cylinder 4, a filter element 6 threadedly connected to the inside of the movable ring 5, a positioning ring 7 fixedly connected to the upper part of the filter cylinder 4, a first compression spring 8 fixedly connected to the bottom of the positioning ring 7, the bottom end of the first compression spring 8 fixedly connected to the top of the movable ring 5, and support plates 9 fixedly connected to the left and right sides of the rear of the inner wall of the housing 1. A shaft 10 is fixedly connected to the inner side of the two support plates 9. A rocker arm 11 is rotatably connected to the surface of the shaft 10. A jacking head 12 is fixedly connected to the front end of the rocker arm 11. A first support plate 13 is fixedly connected to the upper rear side of the inner wall of the machine housing 1. A second support plate 14 is fixedly connected to the lower rear side of the inner wall of the machine housing 1. A vibration motor 15 is installed at the bottom of the first support plate 13. The output end of the vibration motor 15 is in contact with the top of the rear end of the rocker arm 11. A second compression spring 16 is fixedly connected to the top of the second support plate 14. The top end of the second compression spring 16 is fixedly connected to the bottom of the rocker arm 11. A receiving box is installed at the bottom of the inner wall of the machine housing 1.

[0022] refer to Figure 2 A coarse filter frame 17 is movably connected to the upper part of the inside of the feed hopper 2 by bolts, and a coarse filter screen is fixedly connected inside the coarse filter frame 17.

[0023] As a technical optimization of this utility model, by setting a coarse filter frame 17, when the food solution is poured into the feed hopper 2, the food solution can be initially filtered through the coarse filter frame 17 and the coarse filter screen to filter out the larger solids contained therein, which facilitates sampling and at the same time avoids the blockage of the filter cylinder 4 by larger solids.

[0024] refer to Figure 4 A sealing ring 18 is fixedly connected to the top of the filter cylinder 4. The top of the sealing ring 18 fits against the bottom of the feed hopper 2, and the surface of the sealing ring 18 fits against the inner wall of the internal thread ring 3.

[0025] As a technical optimization of this utility model, by setting a sealing ring 18, the connection between the filter cylinder 4 and the bottom of the feed hopper 2 is sealed, which prevents food solution from leaking from the gap at the connection during filtration and affecting its use.

[0026] refer to Figure 4 A rubber protective sleeve 19 is fitted on the surface of the first compression spring 8. The top end of the rubber protective sleeve 19 is fixedly connected to the bottom of the positioning ring 7, and the bottom end of the rubber protective sleeve 19 is fixedly connected to the top of the moving ring 5.

[0027] As a technical optimization of this utility model, by setting a rubber protective sleeve 19, the first compression spring 8 is protected, avoiding the first compression spring 8 from being in contact with the food solution for a long time, which would cause rust and affect its elasticity, thus preventing it from being used normally.

[0028] refer to Figure 1 and Figure 2 A rubber head 20 is fixedly connected to the top of the jacking head 12, and a vibration damping pad 21 is fixedly connected to the bottom of the first support plate 13. The bottom of the vibration damping pad 21 is fixedly connected to the top of the vibration motor 15.

[0029] As a technical optimization of this utility model, the rubber head 20 is set to protect the filter element, reduce the impact force when the top moving head 12 collides with the filter element, and avoid damage to the filter element that affects its use. The vibration damping pad 21 is set to absorb and attenuate the vibration of the top of the vibration motor 15, reduce the impact of the vibration motor 15 on the housing 1 during operation, reduce the resonance of the housing 1, and improve the filtration effect.

[0030] refer to Figure 4 T-shaped blocks 22 are fixedly connected to all four sides of the outer surface of the moving ring 5. T-shaped grooves 23 that cooperate with the T-shaped blocks 22 are opened on all four sides of the inner wall of the filter cylinder 4. The surface of the T-shaped blocks 22 is slidably connected to the inner wall of the T-shaped grooves 23.

[0031] As a technical optimization of this utility model, by setting the T-shaped block 22 and the T-shaped groove 23 in cooperation, when the actuating head 12 strikes the filter element and drives the moving ring 5 to move up and down, the T-shaped block 22 slides up and down inside the T-shaped groove 23, which plays a role in limiting and reinforcing the moving ring 5, so that it can only move vertically up and down inside the filter cylinder 4, thus avoiding the situation where the moving ring 5 falls off and gets stuck, affecting its use.

[0032] The working principle and usage process of this utility model are as follows: The mixed food solution is poured into the feed hopper 2. The food solution enters the filter cylinder 4 through the feed hopper 2 and is filtered by the filter element 6. During filtration, the vibration motor 15 is activated, causing the rear end of the rocker arm 11 to vibrate up and down. The second compression spring 16 supports the rocker arm 11, causing it to spring back, which in turn causes the rear end of the rocker arm 11 to move up and down repeatedly, thus moving the front end up and down. The up and down movement of the front end of the rocker arm 11 causes the actuating head 12 to move up and down. The actuating head 12 strikes the bottom of the filter element during its up and down movement. The first compression spring 8... The moving ring 5 applies downward pressure, causing it to vibrate up and down inside the filter cartridge 4, reducing clogging. When sampling solid residues is required after filtration, the filter cartridge 4 can be held and twisted in the opposite direction to remove it entirely from the bottom of the internal thread ring 3 for easy sampling. When the filter element needs to be replaced, it can be loosened and removed from inside the moving ring 5. This achieves the advantage of tapping the filter element during filtration to cause it to vibrate, preventing clogging and improving filtration efficiency. After filtration, it is convenient to disassemble the filter element and sample solid residues, improving detection results and providing convenience for users.
