When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0028] The utility model provides the following embodiments

[0029] Example 1

[0030] The utility model embodiment provides a centrifugal device for detecting food, such as Figure 1-6As shown, it includes a mounting bracket 1, on which a device housing 2 is mounted, and inside the device housing 2 a crushing assembly 3, a centrifugal assembly 4 and a solid collection assembly 5 are arranged in sequence from top to bottom, and a liquid collection assembly 6 is arranged outside the centrifugal assembly 4;

[0031] The centrifugal assembly 4 includes a screen barrel 400, which is rotatably connected in the equipment housing 2. An electric telescopic member 401 is vertically installed on the top of the inner wall of the screen barrel 400, and a scraper 402 is installed on the working end of the electric telescopic member 401.

[0032] Preferably, the scraper 402 includes a plate sleeve 4020 and an electric plate body 4021 , the electric plate body 4021 is slidably connected in the plate sleeve 4020 , and the electric plate body 4021 is connected to the inner wall of the plate sleeve 4020 via a spring.

[0033] The working principle and beneficial effects of the above technical solution are as follows: when working, food is poured in through the top of the equipment housing 2, and is crushed in turn by the crushing assembly 3 and then enters the centrifugal assembly 4 for centrifugation to achieve solid-liquid separation. The solid obtained after centrifugation is output through the solid collecting assembly 5, and the liquid obtained after centrifugation is output through the liquid collecting assembly 6. During the rotation of the sieve barrel 400 during centrifugation, the electric telescopic member 401 reciprocates and uniformly retracts, contacts the inner wall of the sieve barrel 400 through the scraper 402, and scrapes off the sample attached to the inner wall of the sieve barrel 400. Due to the sliding of the electric plate body 4021 The electric plate body 4021 is connected in the plate sleeve 4020, so that during the centrifugation process, the electric plate body 4021 will be thrown out under the action of centrifugal force until it contacts the inner wall of the sieve barrel 400, and the pressure applied by the electric plate body 4021 to the inner wall of the sieve barrel 400 can be controlled by controlling the centrifugal force, thereby avoiding excessive wear of the inner wall of the sieve barrel 400. At the same time, after the centrifugation is completed, the electric plate body 4021 will be stored in the plate sleeve 4020 under the action of the spring, and the sample attached to the electric plate body 4021 will be scraped off under the action of the plate sleeve 4020 during the process of entering the plate sleeve 4020;

[0034] The utility model adopts a scraper 402 in conjunction with an electric telescopic part 401 to achieve all-round cleaning of the inner wall of the sieve barrel 400. It has a small footprint and a simple structure. The sample is not easy to adhere to the scraper 402. The plate sleeve 4020 can clean the surface of the electric plate body 4021 after centrifugation.

[0035] Example 2

[0036] On the basis of embodiment 1, the crushing assembly 3 includes a primary crushing assembly 300 and a secondary crushing assembly 301, and the secondary crushing assembly 301 is arranged below the primary crushing assembly 300;

[0037] The primary crushing assembly 300 includes a primary driving motor 3000 and a reduction box 3001. The primary driving motor 3000 is installed on the mounting bracket 1. The output end of the primary driving motor 3000 is connected to the input end of the reduction box 3001. A driving shaft 3002 and a driven shaft 3003 are rotatably connected to the equipment housing 2. The output end of the reduction box 3001 is connected to the driving shaft 3002. A driving gear 3004 and a driven gear 3005 are respectively installed on the driving shaft 3002 and the driven shaft 3003. The driving gear 3004 and the driven gear 3005 are meshed with each other. The parts of the driving shaft 3002 and the driven shaft 3003 located in the equipment housing 2 are installed with a flaky crushing roller 3006.

[0038] The working principle and beneficial effects of the above technical solution are as follows: the first-stage crushing assembly 300 and the second-stage crushing assembly 301 cooperate with each other to realize the crushing of food. The first-stage crushing assembly 300 first crushes the food preliminarily, and the second-stage crushing assembly 301 is responsible for further crushing the preliminarily crushed food. The division of labor and cooperation reduces the workload of each stage of the crushing assembly, and at the same time improves the uniformity of the crushed particle size, which is beneficial to improving the centrifugal quality;

[0039] When the primary crushing assembly 300 is working, the primary driving motor 3000 drives the reduction box 3001 to rotate, the reduction box 3001 drives the driving shaft 3002 to rotate, the driving shaft 3002 drives the driving gear 3004 to rotate, the driving gear 3004 drives the driven gear 3005 to rotate, the driven gear 3005 drives the driven shaft 3003 to rotate, the driving shaft 3002 and the driven shaft 3003 rotate to drive the two sets of flaky crushing rollers 3006 to rotate, thereby achieving preliminary crushing of food.

[0040] Example 3

[0041] On the basis of Example 2, the secondary crushing assembly 301 includes a feed barrel 3010 and a secondary electric shaft 3011, the feed barrel 3010 is fixedly connected to the secondary electric shaft 3011, the secondary electric shaft 3011 is rotatably connected in the equipment housing 2, a carrying plate 3012 and a special-shaped push plate 3013 are fixedly connected to the secondary electric shaft 3011, a barrel hammer 3014 is slidably connected to the inner wall of the feed barrel 3010, a push block 3015 is fixedly connected to the inner wall of the barrel hammer 3014, the push block 3015 is always in contact with the upper surface of the special-shaped push plate 3013 through the action of the connecting elastic member 3016 between the barrel hammer 3014 and the inner wall of the feed barrel 3010, a pushing brush 3017 is installed at the bottom of the carrying plate 3012, and a gap is set between the side wall of the carrying plate 3012 and the inner wall of the equipment housing 2, such as Figure 5As shown; wherein, the special-shaped push plate 3013 is located in the barrel hammer 3014, and the special-shaped push plate 3013 is an inclined plate. Under the action of the rebound force of the connecting elastic member 3016, the push block 3015 always applies pressure to the top surface of the special-shaped push plate 3013. As the special-shaped push plate 3013 rotates around the center, because there is a sliding connection between the special-shaped push plate 3013 and the push block 3015, the push block 3015 rises or falls with the rotation of the special-shaped push plate 3013, driving the barrel hammer 3014 to move up or down.

[0042] The working principle and beneficial effects of the above technical solution are as follows: when the secondary crushing component 301 is working, the secondary electric shaft 3011 rotates to drive the feed barrel 3010 to rotate, so that the food that has been initially crushed falls into the supporting plate 3012 through the entrance of the feed barrel 3010, and at the same time, the secondary electric shaft 3011 rotates to drive the special-shaped push plate 3013 to rotate, and the special-shaped push plate 3013 rotates to cooperate with the elastic member 3016 to make the push block 3015 reciprocate up and down. The reciprocating up and down movement of the push block 3015 drives the barrel hammer 3014 to move up and down, and the barrel hammer 3014 moves up and down to beat the food that falls on the supporting plate 3012. When the food particle size is smaller than the distance between the side of the supporting plate 3012 and the inner wall of the equipment shell 2, the food falls downward and is swept into the centrifugal component 4 under the action of the pushing brush 3017.

[0043] Example 4

[0044] On the basis of Example 1, a Y-shaped centrifugal feed channel 3018 is provided under the secondary crushing assembly 301, one of the input ends of the Y-shaped centrifugal feed channel 3018 is located at the output end of the secondary crushing assembly 301, and a feed funnel 3019 is installed at the other input end of the Y-shaped centrifugal feed channel 3018, and the output end of the Y-shaped centrifugal feed channel 3018 is communicated with the input end of the screen barrel 400.

[0045] The working principle and beneficial effects of the above technical solution are as follows: when the food sample to be tested does not need to be crushed, it directly enters the centrifugal assembly 4 through the feed funnel 3019 and the Y-shaped centrifugal feed channel 3018 for centrifugation. The Y-shaped centrifugal feed channel 3018 increases the flexibility of use of the centrifugal equipment.

[0046] Example 5

[0047] On the basis of Example 3, the screen barrel 400 includes a meshing gear ring 403, which is fixedly connected to the top of the screen barrel 400, and a meshing gear 404 is fixedly connected to the secondary electric shaft 3011, and the meshing gear 404 is meshed with the meshing gear ring 403, and a ball 405 is provided between the bottom of the screen barrel 400 and the inner wall of the equipment housing 2.

[0048] The working principle and beneficial effects of the above technical solution are as follows: the rotation of the secondary electric shaft 3011 drives the meshing gear 404 to rotate, the meshing gear 404 drives the meshing gear ring 403 to rotate, and the meshing gear ring 403 drives the sieve barrel 400 to rotate, thereby realizing the centrifugation of food in the sieve barrel 400. The solids remain in the sieve barrel 400 after centrifugation, and the liquids are thrown out of the sieve barrel 400 after centrifugation. The design of the ball 405 can reduce the friction force on the sieve barrel 400 during the rotation process.

[0049] Example 6

[0050] On the basis of Example 1, the sieve barrel 400 includes a sieve drum body 4000 and a sieve drum cover 4001. The sieve drum body 4000 is rotatably connected in the equipment housing 2.

The sieve drum body 4000 is provided with a groove 4004 that cooperates with the sieve drum cover 4001.

[0051] The working principle and beneficial effects of the above technical solution are as follows: during the centrifugation process, the sieve drum body 4000 and the sieve drum cover 4001 are in a mutually coordinated state. After the centrifugation is completed, the electric telescopic part 2 4003 extends to drive the sieve drum cover 4001 to move upward, and the solid sample in the sieve drum body 4000 will slide down along the inner wall of the sieve drum body 4000 under the action of gravity, and finally fall into the solid collection component 5 through the gap between the sieve drum cover 4001 and the sieve drum body 4000.

A solid material receiving box 502 is provided below the output end of the conveying auger 501.

[0054] The working principle and beneficial effects of the above technical solution are as follows: when the solid collection component 5 is working, the auger motor 500 drives the conveying auger 501 to rotate, and the conveying auger 501 rotates to transport the solid sample to the solid receiving box 502, thereby realizing fully automatic collection.

[0055] Example 8

[0056] On the basis of Example 1, the liquid collection component 6 includes a liquid storage tank 600, which is opened at the bottom of the liquid collecting chamber 601 between the screen drum body 4000 and the equipment shell 2.

The scraper 603 is matched in shape with the liquid storage tank 600, and a liquid outlet valve 604 is connected to the liquid collecting chamber 601.

At the same time, during the centrifugation process, the screen barrel 400 drives the scraper 603 to slide along the liquid storage tank 600 through the connecting bent rod 602, thereby pushing the liquid sample in the liquid storage tank 600 to the liquid outlet valve 604. By switching the liquid outlet valve 604, the liquid sample can be automatically collected.
