DETAILED DESCRIPTION

[0026] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] like Figures 1-8 As shown, the chemical raw material screening machine provided in this embodiment includes a backboard 1, a shell 2 and a plurality of screens 3. The shell 2 is a C-shaped structure. A plurality of groups of slide grooves 4 are provided on both sides of the shell 2. The same group of slide grooves 4 are respectively slidably connected to the two sides of the screen 3. The shell 2 is fixedly connected to the backboard 1. A plurality of mesh outlets 5 are provided on the front of the backboard 1. The screen 3 is pulled out of the shell 2 from the mesh outlet 5. A sealing port 6 is provided on the backboard 1 around the mesh outlet 5. A sealing gasket 7 is provided in the sealing port 6. A sealing plate 8 is provided on the outside of the sealing port 6. The sealing plate 8 squeezes the sealing gasket 7 for sealing. The screen 3 is provided with a plug connector 9 on the side close to the sealing plate 8, and a plug connector is provided on the side of the sealing plate 8 close to the mesh outlet 5. Slot 10, the plug connector 9 is slidably connected to the slot 10, and a handle 16 is provided on the outside of the sealing plate 8. Pull the handle 16 to pull the sealing plate 8 out of the shell 2 together with the screen 3. Since the screen 3 and the sealing plate 8 are connected to the plug connector 9 through the slot 10, the screen 3 is pulled out from the slot 10 to replace the screen 3. The screens 3 are arranged in parallel from top to bottom, and the screens 3 are all arranged at an angle. The inclined screen 3 is convenient for pulling out the screen 3. The holes of the screen 3 decrease from top to bottom. The raw materials fall from the top and pass through each screen 3 in turn. Particles of different sizes remain between each screen 3. The particles decrease in size from top to bottom, and the smallest particles fall from the bottom screen 3.

[0028] Further, such as Figure 7As shown, multiple sets of guide wheels 14 are provided inside the chute 4, and the guide wheels 14 are used to guide the screen 3. The top surface and the bottom surface of the chute 4 are fixedly connected with lubricating pads 15, and the lubricating pads 15 are slidably connected to the screen 3. When the screen 3 is pulled out and put in, the corners of the screen 3 are easy to collide with the sides of the chute 4. The guide wheels 14 guide the two sides of the screen 3, and the lubricating pads 15 contain grease to lubricate the contact parts of the screen 3 and the chute 4.

[0029] Further, such as Figure 5 as well as Figure 8 As shown, a sealing groove 21 is provided on the inner surface of the shell 2, and a rubber pad 22 is provided in the sealing groove 21. The rubber pad 22 is in contact with one side of the screen 3. One end of the screen 3 is inserted into the shell 2 and is in close contact with the rubber pad 22 to separate the space between each screen 3.

[0030] Among them, such as Figure 2 As shown, the outer surface of the back plate 1 is provided with a plurality of rotating shafts 17, the rotating shafts 17 are rotatably connected to the baffle 18, and a No. 1 stopper 19 is provided on the outer side of the sealing plate 8. The back plate 1 is provided with a No. 2 stopper 20 near the rotating shaft 17. The No. 1 stopper 19 is used to clamp the baffle 18 on the outer surface of the sealing plate 8, and the No. 2 stopper 20 is used to place the baffle 18. When the baffle 18 is outside the sealing plate 8, the No. 1 stopper 19 limits the baffle 18, and the sealing plate 8 cannot be pulled out at this time. When the sealing plate 8 needs to be pulled out, the baffle 18 is rotated to the position of the No. 2 stopper 20.

[0031] Among them, such as Figure 1 As shown, a top plate 11 is fixedly connected to the top of the shell 2, a feed port 12 is provided on the upper surface of the top plate 11, and a discharge port 13 is fixedly connected to the bottom of the shell 2. The raw materials enter from the feed port 12, and the screened materials flow out from the discharge port 13.

[0032] like Figures 1-8As shown, the principle of the chemical raw material screening machine provided in this embodiment is as follows: the raw material is put into the feed port 12, and the raw material falls from the top and passes through each screen 3 in turn. The screens 3 are arranged in parallel from top to bottom, and particles of different sizes remain between the screens 3. From top to bottom, the particles decrease in size, and the smallest particles fall from the bottom screen 3 and then flow out from the discharge port 13. Then, the screens 3 are pulled out in order from bottom to top, and the particles of different sizes remaining between the screens 3 fall in turn. The screen 3 and the sealing plate 8 are connected to the plug connector 9 through the slot 10. When the screen 3 needs to be replaced, When changing, the screen 3 is pulled out from the slot 10 to replace the screen 3. When the screen 3 is pulled out and put in, the corner of the screen 3 is easy to collide with the side of the chute 4. The guide wheel 14 guides both sides of the screen 3. The lubricating pad 15 contains grease to lubricate the contact part of the screen 3 and the chute 4. The screens 3 are all tilted, and the raw materials between the screens 3 slide to the lower part. A rubber pad 22 is provided in the sealing groove 21. The rubber pad 22 conflicts with one side of the screen 3. The end of the screen 3 inserted into the shell 2 is in close contact with the rubber pad 22 to separate the space between each screen 3.

[0033] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0034] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0035] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
