Description

Technical Field

[0001] The present invention relates to the technical field of pretreatment devices, and particularly to a chemical raw material pretreatment device. Background Art

[0002] Traditional pretreatment methods and devices may have deficiencies in removing certain impurities or meeting specific treatment requirements. They require manual operation and monitoring, resulting in high labor intensity and being prone to operation errors due to human factors. There is a need for a more automated and intelligent pretreatment device to achieve efficient and stable production.

[0003] The patent with application number 202123396604.7 relates to a chemical raw material pretreatment device, which particularly includes a working frame. One side of the inner cavity of the working frame is fixedly connected with an inclined frame. One side of the inner cavity of the inclined frame is fixedly connected with several inclined rods obliquely. This patent relates to the technical field of chemical production. By arranging several inclined rods inside the inclined frame, large solid particle raw materials formed into large chunks can be intercepted by the several inclined rods and sent into the interior of a crushing frame. By arranging the inclined rods, not only can large raw materials be prevented from damaging the sieve frame, but also due to the inclined arrangement of the inclined rods, the raw materials can be sent into the interior of the crushing frame for crushing, thereby avoiding waste of raw materials. At the same time, by arranging a rectangular ring plate at the front of the containing frame, when the crushing roller inside the crushing frame crushes large raw materials, it can also drive the containing frame to vibrate, thereby screening and separating small raw materials to the top of the sieve frame. However, when the device rolls the material, the material will adhere to the rolling roller, resulting in insufficient rolling. At the same time, when filtering the raw materials, residues will remain on the filter plate, easily causing blockage of the screening. Therefore, a chemical raw material pretreatment device is proposed to solve the above-mentioned problems. Summary of the Invention

[0025] Working principle: When chemical raw materials are used, they need to be pretreated first. The raw materials can be put into the feed port 3 by staff or machinery, and then enter the reaction kettle 1 through the feed port 3. At this time, the staff of the push plate starts the motor 2 to work. The motor 2 drives the reciprocating screw rod 4 to rotate. The rotation of the reciprocating screw rod 4 drives the fixed rod 5 to rotate. The rotation of the fixed rod 5 drives the rolling cylinder 6 to rotate to roll and crush the material. Then, it is screened through the filter plate 10 and discharged from the discharge port 11. While the material is being rolled, the rotation of the reciprocating screw rod 4 drives the moving sleeve 71 to reciprocate through the reciprocating chute on the circumferential surface. The moving sleeve 71 drives the articulated rod 72 to move through the hinge point. The articulated rod 72 then drives the arc-shaped scraper 73 to reciprocate through the hinge point to clean the circumferential surface of the rolling cylinder 6, avoiding the adhesion of powder during rolling, reducing the time for the equipment to stop for maintenance due to failures, thereby improving the operating efficiency of the entire pretreatment device and also improving the overall working efficiency. While the raw materials are being rolled, the reciprocating screw rod 4 drives the rotating plate 74 to rotate to clean the surface of the filter plate 10, preventing the filter plate 10 from being blocked due to the accumulation of raw materials. While rotating, the rotating plate 74 drives the reciprocating screw rod 75 to rotate. The reciprocating screw rod 75 drives the pulley 76 to rotate. The pulley 76 drives itself to rotate through the contact between the circumferential surface and the filter plate 10. The pulley 76 drives the reciprocating screw rod 75 to rotate itself. The reciprocating screw rod 75 drives the telescopic scraper 77 to reciprocate through the chute on the circumferential surface. The reciprocating movement of the telescopic scraper 77 will clean the filter plate 10, increasing the cleaning area of the filter plate 10, making the screening of raw materials more meticulous, improving the quality of raw materials, and making the overall working efficiency of the equipment higher.

[0026] While the raw materials are being rolled, the rotation of the reciprocating screw rod 4 drives the sliding sleeve 81 to reciprocate through the reciprocating chute. The sliding sleeve 81 drives the inclined block 82 to reciprocate. The inclined block 82 drives the Z-shaped plate 83 to move through the inclined plane. The Z-shaped plate 83 drives the pulley 84 to move. The pulley 84 drives itself to move through the contact between the circumferential surface and the inner wall of the guide plate 85. The pulley 84 drives the baffle 86 to move and close. When the inclined block 82 leaves, the baffle 86 opens again through the torsion spring to achieve intermittent feeding, avoiding poor rolling effect caused by excessive raw materials, making the product quality better, and also avoiding equipment damage caused by excessive materials, improving the service life of the equipment, ensuring the overall efficiency of the equipment. While the filter plate 10 is being scraped, the movement of the telescopic scraper 77 drives the extrusion rod 89 to move. The extrusion rod 89 drives the inclined block 88 to move through the inclined plane. The inclined block 88 drives the knocking rod 87 to move.

[0028] Working principle: When raw materials enter, the baffle 86 is intermittently opened to drive the movement of the third inclined block 91. The third inclined block 91 drives the movement of the sliding rod 92 through the inclined plane. The sliding rod 92 reciprocates through the spring. The sliding rod 92 then drives the movement of the first roller 93 through the front contact surface. The first roller 93 drives the rotation of the third reciprocating screw rod 94.

The second roller 98 rotates by contacting the inner wall of the feeding port 3. The second roller 98 drives the rotation of the connecting rod 96. The connecting rod 96 drives the rotation of the stirring plate 97 to stir the raw materials, avoiding the blockage of the raw materials in the feeding port 3, resulting in a reduction in productivity, increasing the feeding speed of the raw materials, making the working efficiency of the equipment better, improving the overall quality of the product, and making the overall pretreatment effect better. While dredging the feeding port 3, the reciprocating movement of the moving plate 95 drives the reciprocating movement of the pressing rod 99. The pressing rod 99 drives the reciprocating movement of the convex block 912 through the arc surface at the top to contact the convex block 912.
