[0002] Chemical raw materials are the foundation of the chemical industry, and their processing is crucial for improving product quality, reducing production costs, and promoting environmental protection and sustainable development. Filtration is a critical step in the processing process, directly impacting the performance of the final product. When replacing the filter element in the device, the operator must open the housing and replace the used filter element with a new one after each filtration cycle. This also requires changing different filter elements when filtering different raw materials.

Each disassembly and installation requires frequent opening and closing of the device to replace the filter element. This cumbersome process seriously affects production efficiency, especially in chemical production where frequent filter element replacement is required. Utility Model Content

The left side of the device housing 1 is rotatably connected to the dividing wheel 3, and the left side of the dividing wheel 3 is fixedly connected to the handwheel 4. Four filter elements 5 are detachably provided on the right side of the dividing wheel 3. The filter element 5 is completely in the device housing 1 and the two do not touch each other. The device housing 1 is a horizontal hollow cylinder, and the four filter elements 5 are all horizontal hollow cylinders. The filter elements 5 are distributed on the indexing wheel 3 at equal angles and intervals, and are equidistant from the center of the circle. A feed port is provided on the side of the filter element 5 away from the indexing wheel 3. A terminal filter screen 6 is embedded in the top of the filter element 5 close to the indexing wheel 3. A feed mechanism is connected to the right side of the device housing 1. The feed mechanism is used to input chemical raw materials into the filter element 5 through the feed port. The left end of the sliding feed bin 7 is connected to the right side of the device housing 1, and the right end of the sliding feed bin 7 is connected to the feed bin baffle 71. The feed bin baffle A self-locking buckle 72 is hinged on the left side of 71, and a finger plate 73 is connected to the self-locking buckle 72. A spring 74 is connected between the finger plate 73 and the feed bin baffle 71. A feed channel 75 is provided on the right side of the top of the sliding feed bin 7. An L-shaped tube 81 is slidingly provided in the sliding feed bin 7. The top of the L-shaped tube 81 is connected to the hopper 8. The left end of the L-shaped tube 81 is connected to a fixed through-hole plug 76 that is adapted to the feed port on the dividing wheel 3. The fixed through-hole plug 76 is made of rubber material resistant to corrosion by chemical raw materials.

[0020] like Figure 1 、 Figure 2 and Figure 4 As shown, it also includes a collecting port 9, a storage shell 10, a diverter pipe 11, an electric-controlled valve feed port 12, a storage chamber 13, a valve discharge port 14 and a support frame 15. The storage shell 10 is connected to the bottom of the device shell 1. Four storage chambers 13 are provided in the storage shell 10. The collecting port 9 is embedded in the left side of the top of the storage shell 10. The collecting port is located below the terminal filter screen 6 of the filter element 5 below. The lower end of the collecting port 9 is connected to the diverter pipe 11. The lower end of the diverter pipe 11 is provided with four electric-controlled valve feed ports 12 arranged at intervals. The lower ends of the four electric-controlled valve feed ports 12 are respectively connected to the four storage chambers 13. The lower end of each storage chamber 13 is connected to the valve discharge port 14. The valve discharge port 14 passes through the lower end of the storage shell 10, and the top of the support frame 15 is connected to the bottom end of the storage shell 10.

[0021] After the filter element 5 is removed from the dividing wheel 3, the operator puts in the required filter element 5 and reinstalls it on the dividing wheel 3. The side of the filter element 5 with the terminal filter screen 6 needs to be close to the side of the dividing wheel 3, and the part of the filter element 5 embedded with the terminal filter screen 6 needs to be vertically facing upward. Then the operator turns the hand wheel 4 in one direction until the hand wheel 4 drives the dividing wheel 3 to rotate 90 degrees. At this time, a filter element 5 that has not been replaced will be driven by the dividing wheel 3 to the bottom of the opening at the top of the device housing 1. The operator repeats the above disassembly and installation steps, and turns the hand wheel 4 again to control the dividing wheel 3 to rotate to another filter element 5 that has not been replaced, until all the filter elements 5 mounted on the right side of the dividing wheel 3 are replaced with matching ones. The filter element 5 used; the operator puts the raw material into the hopper 8, and a valve (not shown in the figure) is built in the L-shaped tube 81 connected to the bottom of the hopper 8. The valve can control whether the raw material in the hopper 8 can be transported into the L-shaped tube 81. The raw material enters the filter element 5 through the L-shaped tube 81 and the fixed through-hole plug 76. The raw material will be filtered layer by layer in the filter element 5 and then leak out from the terminal filter screen 6 for collection. After the filter element 5 filters a certain amount of raw material, the filtration effect will deteriorate. At this time, the operator stops feeding, and then rotates the handwheel 4 to drive the dividing wheel 3 to rotate an unused filter element 5 to the corresponding position where the sliding feed bin 7 can smoothly feed the material. The operator inserts the fixed through-hole plug 76 into the right side of the new filter element 5 again and adds raw material again. In this way, the operator can repeat the above-mentioned operation method for the used filter element 5 until all the filter elements 5 can no longer be effectively filtered. The operator repeats the above-mentioned operation of replacing the filter element 5. At this point, the operator does not need to frequently replace a filter element 5, but can replace all the filter elements 5 at once after use. The raw material filtering operation is performed again.The fixed through-hole plug 76 connected to the end of the L-shaped tube 81 will stop feeding when the valve is closed. At this time, the operator pushes the L-shaped tube 81 to the right and the hopper 8 is pulled out. The L-shaped tube 81 drives the fixed through-hole plug 76 to pull out the filter element 5. The L-shaped tube 81 moves to the right to push the two self-locking buckles 72 apart, and the spring 74 is compressed. After the L-shaped tube 81 is completely stuck in the self-locking buckle 72, the spring 74 will push the self-locking buckle 72 back to fix the L-shaped tube 81. When the operator pulls the finger plate 73 to press the spring 74, the L-shaped tube 81 is loosened, pushing the L-shaped tube 81 to the left and driving the fixed through-hole plug 76 connected to its end to be inserted into the filter element 5, closing the valve on the L-shaped tube 81 ( When the filter element 5 is opened (not shown in the figure), the raw materials in the L-shaped tube 81 will flow into the filter element 5 along the L-shaped tube 81 through the fixed through-hole plug 76, and the feeding process is more stable. The collection port 9, the storage shell 10, the diversion pipe 11, the electric control valve feed port 12, the storage chamber 13 and the valve discharge port 14 are used together to allow the filtered raw materials to be separately packed in different storage chambers 13. Each of the four electric control valve feed ports 12 can be opened and closed individually. The valve discharge port 14 only needs to be unscrewed to allow the raw materials stored in the storage chamber 13 to leak out, which is convenient for the operator to collect. The support frame 15 connected to the lower end of the storage shell 10 can control the overall height of the entire equipment, which is convenient for the operator to operate.
