[0037] The opening and closing part 14 includes a pressurizing cylinder 33 fixedly installed in the machine body 1, one end of the sliding cover 13 is fixedly connected to a driving rod 34, the driving rod 34 passes through one side of the kneading box 2, and is slidably connected to the kneading box 2 in the horizontal direction, one end of the driving rod 34 is fixedly connected to a pressurizing plate 35 slidably connected to the inner wall of the pressurizing cylinder 33, a delivery pump 36 is fixedly connected in the machine body 1, and the output end of the delivery pump 36 is connected to one end of the pressurizing cylinder 33.

[0038] In this embodiment, stearic acid, metal oxide and catalyst are input into the kneading box 2, and the driving motor 28 is started and decelerated by the reducer 31, so that the second gear 29 and the third gear 30 respectively drive the kneading paddles 3 on both sides to rotate in opposite directions, and the raw materials are kneaded and sheared in the kneading box 2 in a solid state to generate a stearate powder coarse product, and the conveying pump 36 is started to pressurize the pressure cylinder 33, so that the driving rod 34 pushes the sliding cover 13 to slide, and the connection between the kneading box 2 and the output groove 11 is opened, and the stearate powder coarse product can be pushed into the middle output groove 11 under the rotation of the kneading paddle 3. At this time, the second gear 29 drives the second belt 42 to make the output shaft 12 for the conveying screw 10 rotate slowly, and the product in the output groove 11 is pushed into the connecting pipe 15 for output.

[0039] The output end of the driving motor 28 drives the driving wheel 40 to rotate at high speed through the first belt 41, and the driving wheel 40 drives the rotating rod 17 to make the crushing knife 8 and the fan blade 43 rotate at high speed. During the rotation of the fan blade 43, the powder raw material in the connecting pipe 15 is pumped into the screening cylinder 7. The crushing knife 8 rotates at high speed to crush the raw material in the screening cylinder 7 and push it to the surrounding sieve holes. The granular raw material reaching the required size can be transported to the fixed cylinder 6 through the sieve holes, and the required stearate powder is output through the output pipe 16, while the raw materials with larger particles continue to be crushed and screened in the screening cylinder 7 until they reach the required size and are output. Subsequently, the material can be sent to the silo through the three-stage cyclone separator, and the product is obtained after being packaged by the automatic packaging machine.

[0040] During the rotation of the rotating rod 17, the gear plate 20 will be driven to rotate, so that the clamping rod 21 and the screening drum 7 will rotate synchronously, and the position of the upper end of the screening drum 7 will be switched. The gear plate 20 drives the first gear 24 and the rotating column 23 to rotate, so that the top end of the impact rod 26 continuously rotates to impact the upper side of the screening drum 7, causing the upper end of the screening drum 7 to shake, and the powder particles blocked in the sieve hole are discharged. In this way, the screening drum 7 can be continuously screened and self-cleaned simultaneously, thereby reducing the probability of blockage and improving the screening efficiency. Additions can be made in the fixed drum.

[0041] The device has a high degree of automation and can continuously carry out a multi-step reaction process of stearate with high production efficiency. By controlling the delivery pump 36 to extract hydraulic oil from the pressurizing cylinder 33, the sliding cover 13 can be slid in the opposite direction to separate the output groove 11 from the inner wall of the kneading box 2, so that the raw materials in the kneading process can continue to undergo kneading reaction in the kneading box 2. During the output process, the kneading paddle 3 will fully push the raw materials in the kneading box 2 into the middle output groove 11, and the output process is more efficient and thorough. The overall synchronous operation of the equipment can be achieved through only one set of drive motors 28, and maintenance and overhaul are more convenient and efficient. After the previous set of kneaded raw materials are transported out of the kneading box 2, the sliding cover 13 can be covered, and the next set of raw materials to be kneaded can be put into the kneading box 2. At this time, the output raw materials can be simultaneously crushed and screened in the screening cylinder 7 to improve production efficiency.

[0042] The water vapor generated by the kneading reaction in the kneading box 2 is vacuumed and discharged into the three-proof pulse dust collector 37 by the vacuum suction pump 38. The powdered material brought out during the drainage process is dedusted by the three-proof pulse dust collector 37 and then returned to the kneading box 2 through the circulation pipe 39 for cyclic kneading processing. Under the action of the catalyst, the stearic acid and metal oxide in the device directly undergo shear kneading reaction in the solid phase to generate stearate products. The catalyst used does not contain metal ions, does not need to be saponified with sodium hydroxide, does not contain sodium ions, has higher purity, and expands the scope of product use. At the same time, the reaction process does not use water as the reaction medium, so there is no wastewater discharge. It is an environmentally friendly stearate production technology. The powder product does not need to be dried and the production cost is low. It is an energy-saving stearate production technology. After dust removal by the three-proof pulse dust collector 37, the exhaust gas can meet the emission standards and is more environmentally friendly.
