[0026] See also Figure 1 In an embodiment of the present invention, a high-efficiency detection process for heavy metal ions in food comprises the following steps: Step 1: Select the food to be tested and cut it into the required size. At the same time, put the cut food into the rolling equipment, and under the action of the rolling equipment, the food is rolled into the required particle size; Step 2: Put the food particles into the detection device, and under the action of the detection device, automatically add the color developer so that the color developer is mixed with the food particles to perform color development detection on the food; Step 3: After the test is completed, the food and developer mixed solution can be automatically discharged under the action of the test equipment, and cleaning liquid is added to the test equipment to clean the test equipment, thereby ensuring the accuracy of subsequent food testing; Step 4: Based on the obtained test data, compare it with the standard data to confirm whether the heavy metal ions in the food exceed the standard.
[0027] See also Figure 2~Figure 9 , the detection equipment comprises: A bracket 1, on which a fixing plate 2 is fixedly mounted, and a supporting plate 3 is also fixedly mounted on the bracket 1; See also Figure 2-Figure 4 , Figure 6 , Figure 7 , a mixing switching component is arranged on the support plate 3, and a processing tank 9 which is symmetrically arranged and connected to the mixing switching component is also arranged on the support plate 3. The mixing switching component can drive the processing tank 9 to rotate, and the mixing switching component can also drive the processing tank 9 to move around the central axis of the support plate 3. The mixing switching component includes a rotating sleeve 5 rotatably mounted on the support plate 3, and a rotating plate 6 is fixed to the end of the rotating sleeve 5 away from the support plate 3. A rotating rod 7 arranged in the rotating sleeve 5 is rotatably mounted on the support plate 3, and a large gear 8 is fixed to the end of the rotating rod 7 away from the support plate 3. A small gear 10 meshing with the large gear 8 is fixed to the circumferential outer wall of the processing tank 9.
[0028] In detail, when conducting heavy metal testing on food, the food needs to be added into the processing tank 9. In order to ensure that the food can be tested smoothly, at this time, the rotating rod 7 rotates, driving the large gear 8 to rotate. Since the large gear 8 is engaged with the small gear 10, the processing tank 9 fixed with the small gear 10 rotates. Under the action of the processing tank 9, the materials in the processing tank 9 are mixed and processed. When the processing is completed, the materials in the processing tank 9 need to be discharged to the outside of the processing tank 9. At this time, under the action of the rotating sleeve 5, the rotating plate 6 is driven to rotate, thereby driving the processing tank 9 to rotate around the rotating sleeve 5. Under the action of the triggering discharge mechanism, the materials in the processing tank 9 are discharged. When other foods need to be tested, the rotating sleeve 5 rotates again, so that the processing tank 9 returns to the initial position to test the food again.
[0029] See also Figure 2-Figure 4 , Figure 6-Figure 9 , a storage tank 22 is fixedly mounted on the fixed plate 2 and is symmetrically arranged, an intermittent feeding mechanism connected to the storage tank 22 and the processing tank 9 is arranged on the fixed plate 2, the intermittent feeding mechanism can be actuated when the storage tank 22 moves, and the material in the storage tank 22 is transported to the processing tank 9, the intermittent feeding mechanism includes a cleaning pipe 18 movably mounted in the processing tank 9, a feeding pipe 20 is fixedly mounted in the cleaning pipe 18, a fixed wheel 21 is fixed to the circumferential outer wall of the feeding pipe 20, a conveying assembly connected to the storage tank 22 is arranged on the fixed plate 2, the conveying assembly is connected to the fixed wheel 21, the cleaning pipe 18 is connected to the cleaning assembly, wherein the conveying assembly includes a fixed A support sleeve 23 is installed at the bottom of the storage tank 22, and a hollow rod 24 that penetrates the storage tank 22 is movably installed in the support sleeve 23. A sealing ring 26 is fixed to one end of the hollow rod 24 facing the storage tank 22. An elastic structure connected to the hollow rod 24 is provided on the fixed plate 2, and the elastic structure is connected to the fixed wheel 21. The elastic structure mentioned above includes a feed trough 25 opened on the hollow rod 24, a movable plate 28 is fixed on the hollow rod 24, and a tilting block 29 is fixed on the side of the movable plate 28 away from the storage tank 22. A spring 27 abutting against the movable plate 28 is sleeved on the hollow rod 24 and the support sleeve 23, and the tilting block 29 cooperates with the fixed wheel 21.
[0030] It should be noted that when food is added into the processing tank 9, a color developer needs to be added into the processing tank 9 to color the heavy metals contained in the food. A color developer is added into the storage tank 22. In the initial state, the spring 27 is in a compressed state, so that the movable plate 28 is located at the end of the stroke away from the storage tank 22, so that the hollow rod 24 is located at the end of the stroke toward the support plate 3, the blocking ring 26 is in contact with the bottom of the storage tank 22, and the feed chute 25 is located outside the storage tank 22, thereby ensuring that the storage tank 22 is in a blocked state. When the color developer needs to be transported, the rotating sleeve 5 drives the rotating plate 6 to rotate, thereby driving the processing tank 9 to move. The processing tank 9 will also drive the cleaning pipe 18 to move, and the cleaning pipe 18 will also drive the feeding pipe 20 to move, thereby driving the fixed wheel 21 to move around the rotating sleeve 5. When the fixed wheel 21 abuts against the inclined surface of the inclined block 29, the feeding pipe 20 moves to the hollow Directly below the rod 24, under the action of the fixed wheel 21, the movable plate 28 fixed with the tilting block 29 is moved, thereby driving the hollow rod 24 to move along the length direction of the support sleeve 23 and toward the storage tank 22, so that the blocking ring 26 is separated from the bottom of the storage tank 22, and the hollow rod 24 will also drive the feeding trough 25 to move until the feeding trough 25 moves into the storage tank 22, so that the color-developing liquid in the storage tank 22 enters the hollow rod 24 through the feeding trough 25 and is transported to the feeding pipe 20, so that the color-developing liquid is transported to the processing tank 9 through the feeding pipe 20. When the fixed wheel 21 is separated from the tilting block 29, the spring 27 is elastically released, so that the hollow rod 24 is reset, and the feeding trough 25 is moved again to the outside of the storage tank 22, so that the storage tank 22 is blocked again, and the feeding pipe 20 will pass over the hollow rod 24. Since the port size of the feeding pipe 20 is large, it is ensured that the color-developing liquid can completely enter the feeding pipe 20.
[0031] See also Figure 2-Figure 4 , Figure 6 , a cleaning component is arranged on the fixed plate 2 and connected to the intermittent feeding mechanism. The cleaning component can transport cleaning liquid into the processing tank 9 after the processing in the processing tank 9 is completed. The cleaning component includes a conduit 16 movably mounted on the fixed plate 2, and the conduit 16 is connected to a connecting pipe 17 which is symmetrically arranged and connected to the conduit 16. The cleaning pipe 18 is provided with a plurality of through holes 19 which are equidistantly distributed around the circumference, and the connecting pipe 17 is connected to the cleaning pipe 18.
[0032] Furthermore, after the heavy metal detection of food is completed, the processing tank 9 needs to be cleaned to ensure that it will not affect the subsequent detection of food. At this time, under the action of the conduit 16, the cleaning liquid is transported to the connecting pipe 17, and then transported to the cleaning pipe 18 through the connecting pipe 17. The cleaning liquid in the cleaning pipe 18 will be discharged through the pipe opening at the bottom of the cleaning pipe 18 and the through hole 19 on the side wall to clean the bottom and side wall of the processing tank 9.
[0033] See also Figure 2-Figure 7 , a trigger discharge mechanism is arranged on the support plate 3 and connected to the processing tank 9, the trigger discharge mechanism can be activated when the processing tank 9 rotates around the central axis of the support plate 3 to adjust the conduction state of the processing tank 9 and discharge the material in the processing tank 9 to the outside of the processing tank 9, the trigger discharge mechanism includes a guide rail 4 fixedly installed on the support plate 3, a conveying pipe 12 is fixedly installed at the bottom of the processing tank 9, a spiral track 13 is fixed in the conveying pipe 12, a driven component connected to the conveying pipe 12 is arranged on the support plate 3, and the driven component is connected to the guide rail 4, wherein the driven component includes a movable rod 14 movably installed in the conveying pipe 12, a sealing gasket 11 cooperating with the processing tank 9 is fixed on the end of the movable rod 14 away from the support plate 3, and a limiting wheel 15 abutting against the guide rail 4 is fixed on the end of the movable rod 14 facing the support plate 3.
[0034] Furthermore, after the food inspection is completed, the solution in the processing tank 9 needs to be discharged to facilitate the subsequent food inspection. The guide rail 4 can be divided into two sections, the first section is horizontally arranged, and the second section is arc-shaped and convex. In the initial state, the limiting wheel 15 is located in the horizontal section, so that the movable rod 14 is located at the end of the stroke away from the processing tank 9, and under the action of the sealing gasket 11, the processing tank 9 is in a blocked state. When the food inspection is completed, the rotating sleeve 5 rotates to move the rotating plate 6 and the processing tank 9, thereby driving the limiting wheel 15 to slide on the guide rail 4. When the limiting wheel 15 moves to abut against the convex position of the guide rail 4, it drives the limiting wheel 15 toward The movable rod 14 drives the sealing gasket 11 to separate from the bottom of the processing tank 9. At this time, the processing tank 9 is in a conducting state, and the solution in the processing tank 9 is discharged through the delivery pipe 12. Since the cleaning liquid is being added to the processing tank 9 at this time, the cleaning effect of the processing tank 9 is better. When the solution flows through the spiral track 13, the solution is discharged in a spiral shape. Under the action of the spiral flow, the solution in the processing tank 9 is attracted to ensure a better cleaning effect on the processing tank 9. When the cleaning is completed, the rotating sleeve 5 continues to rotate, so that the limiting wheel 15 returns to the horizontal section of the guide rail 4 again, so that the processing tank 9 is in a blocked state again.
