Pure kaolin is white, delicate, and soft, and has good physical and chemical properties such as plasticity and refractoriness.
[0003] At present, the quality control method adopted before kaolin is produced and used is to test kaolin through manual laboratory testing, which leads to a long sampling and testing cycle. At the same time, due to the problems of the number of samples and the sampling location, the sampling representativeness deviation is large, and it is impossible to accurately judge whether the kaolin raw materials are qualified. In addition, there is only simple manual screening of the raw materials, resulting in high labor costs and unstable product quality. Utility Model Content

At the same time, due to the problems of the number of samples and the sampling position, the sampling representativeness deviation is large, and the qualification of the kaolin raw materials cannot be accurately judged. In addition, there is only a simple manual screening of the raw materials, resulting in high labor costs and unstable product quality.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Embodiment 1:
[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the automatic screening equipment for kaolin raw materials includes a screening box 1 and a laser detector 3. A conveyor belt 2 passing through both sides is arranged inside the screening box 1. The laser detector 3 is located above the middle position of the conveyor belt 2. A pushing assembly 4 is arranged on the inner wall of one side of the screening box 1. A conveyor belt 5 is arranged inside the screening box 1 in a direction perpendicular to the conveyor belt 2, and one end of the conveyor belt 5 extends to the bottom of the conveyor belt 2.
[0024] like Figure 2 As shown, the pushing assembly 4 includes a pushing cylinder 401, which is fixedly connected to the inner wall of the screening box 1 on the opposite side of the conveyor belt 5. A pushing plate 411 is fixedly connected to the output end of the pushing cylinder 401. The bottom of the pushing plate 411 is in contact with the top surface of the conveyor belt 2. By starting the pushing cylinder 401 to drive the pushing plate 411 to move, the unqualified raw materials are pushed out from the conveyor belt 2 for screening.
[0025] like Figure 1 and Figure 2 As shown, the outer wall of the conveyor belt 5 is fixedly connected to a plurality of equidistant array receiving hoppers 501, and the raw materials pushed out from the conveyor belt 2 are received by the receiving hoppers 501. Then, the conveyor belt 5 drives the receiving hoppers 501 to move, and the raw materials inside the receiving hoppers 501 are poured out to prevent the raw materials from falling on the conveyor belt 5 and being broken and scattered.
[0026] like Figure 1 and Figure 2 As shown, two groups of baffles 502 are fixedly connected to the inner wall of the screening box 1, and the two groups of baffles 502 are respectively located on both sides of the conveyor belt 5 and are attached to one side of the conveyor belt 2. The baffles 502 are used to protect the pushed raw materials to prevent them from falling off the conveyor belt 5.
[0027] like Figure 1 and Figure 4 As shown, two groups of guide plates 7 are fixedly connected to one side of the screening box 1, and the two groups of guide plates 7 are symmetrically arranged on the top of the conveyor belt 2. The two groups of guide plates 7 are used to guide the raw materials on the conveyor belt 2, and the raw materials at different positions are aligned in a straight line and moved by the conveyor belt 2, so that the raw materials can be accurately moved to the bottom of the laser detector 3 for detection, thereby improving the accuracy of the detection.
[0028] like Figure 1 As shown, a fixed plate 6 is fixedly connected to the inner wall of one side of the screening box 1, and a material stripping plate 601 is rotatably connected to the bottom of the fixed plate 6. The material stripping plate 601 is located on the upper side of the conveyor belt 2. When the conveyor belt 2 drives the raw materials to move to the position of the material stripping plate 601, the material stripping plate 601 is against the raw materials, and then rotates to the position between the two groups of raw materials, and then can increase a certain thrust on the raw materials to separate the two groups of raw materials that are stuck to each other, thereby avoiding the two groups of raw materials from being stuck to each other and being unable to be screened, thereby improving the stability of the detection.
[0029] Embodiment 2:
[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the automatic screening equipment for kaolin raw materials includes a screening box 1 and a laser detector 3. A conveyor belt 2 passing through both sides is arranged inside the screening box 1. The laser detector 3 is located above the middle position of the conveyor belt 2. A pushing assembly 4 is arranged on the inner wall of one side of the screening box 1. A conveyor belt 5 is arranged inside the screening box 1 in a direction perpendicular to the conveyor belt 2, and one end of the conveyor belt 5 extends to the bottom of the conveyor belt 2. The pushing assembly 4 includes an air blowing pipe 402. A fixing frame 421 is fixedly connected to the side of the screening box 1 in the opposite direction to the conveyor belt 5. The air blowing pipe 402 is fixedly connected to the side wall of the fixing frame 421. The air inlet end of the air blowing pipe 402 is connected to an air source. When unqualified raw materials are detected on the conveyor belt 2, the air source supplies air to the air blowing pipe 402, and the gas is blown out from the air blowing pipe 402 onto the raw materials, and the raw materials are blown out from the conveyor belt 2 for screening.
[0031] Comparing the two methods of pushing materials by the pushing cylinder 401 and the blowing pipe 402 mentioned above, the pushing method of the pushing cylinder 401 is stable and will not cause splashing of the raw materials due to the different sizes of the raw materials, but there will be raw materials remaining on the conveyor belt 2, while the pushing method of the blowing pipe 402 is clean and will not cause the raw materials to remain on the conveyor belt 2, but due to the different sizes of the raw materials, the position and distance of the raw material blowing will be unstable, causing splashing of the raw materials. The two methods each have their own advantages and disadvantages, and the specific selection method is selected according to the actual production conditions or structure.
[0032] The working principle of the utility model is as follows: when the user uses it, the sorted raw materials fall onto the conveyor belt 2, and then are driven by the conveyor belt 2 to be transported to the inside of the screening box 1. When the raw materials are driven by the conveyor belt 2 to move to the bottom of the laser detector 3, the laser detector 3 is used to detect whether the raw materials are qualified. Qualified raw materials continue to be conveyed to the next process production line on the conveyor belt 2. When unqualified raw materials are detected, the pushing component 4 is started, and the pushing component 4 pushes the unqualified raw materials from the conveyor belt 2, and then falls onto the conveyor belt 5. The unqualified raw materials are picked up by the conveyor belt 5 and then transported to the waste bin, thereby completing the screening of whether the kaolin raw materials are qualified or not, avoiding the long period of sampling and detection and the deviation of sampling representativeness, and improving the stability of raw material use.
[0033] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
