Description

Technical Field

[0001] The utility model relates to the technical field of thiophanate-methyl production, in particular to centrifugal washing integrated equipment for thiophanate-methyl production. Background Art

[0002] In the process of producing methyl thiophanate, sodium thiocyanate and methyl chloroformate react directly in water under the catalytic action of a phase transfer catalyst to produce methyl isothiocyanate formate, and then the methyl isothiocyanate formate in the aqueous phase is extracted with toluene and added dropwise to a prepared o-phenylenediamine toluene solution of a certain concentration to finally produce methyl thiophanate, which is then centrifuged, washed, and dried to obtain a finished product.

[0003] In the traditional production process, washing and centrifugal separation are usually carried out in different equipment, which not only increases the equipment investment and floor space, but also leads to cumbersome production process, easy loss and pollution in the material transfer process, affecting product quality and production efficiency. In addition, some existing washing and separation equipment have deficiencies in stirring effect and scraping and cleaning of materials, and it is difficult to meet the requirements of high-quality production of methyl thiophanate. Therefore, it is of great practical significance to develop a device that integrates washing and centrifugal functions and has excellent performance. Utility Model Content

[0007] Preferably, a first rotating motor is fixedly mounted on the bracket, a pulley is fixed to the output shaft of the first rotating motor, and a transmission belt is provided between the pulley and the outside of the washing tank.

[0008] Preferably, a first gear is fixed to the top of the stirring shaft, a second rotating motor is fixed to the top of the filter cartridge, a second gear is fixed to the output shaft of the second rotating motor, and the second gear is meshed with the first gear.

[0009] Preferably, the stirring branches are equidistantly distributed in the vertical direction of the stirring shaft, and the scraper is rotatably mounted on a horizontal movable frame.

[0010] Preferably, a horizontally arranged hydraulic cylinder is fixed on the stirring shaft, and an output shaft of the hydraulic cylinder is fixed to the horizontal movable frame.

[0011] Preferably, a transmission box is fixed on the side of the stirring shaft close to the scraper, the installation shaft of the scraper extends to the interior of the transmission box and is fixed with a third gear, a rack is fixed inside the transmission box, the third gear is meshed with the rack, and a horizontally arranged movable baffle is also fixed on the horizontal movable frame, and the movable baffle passes through the bottom end of the transmission box through a guide groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Simplified process: In the traditional process, washing and centrifugal separation are performed in different equipment, while this equipment integrates the two functions into one. This avoids the cumbersome process of transferring materials between different equipment, reduces production time, and greatly improves production efficiency.

[0014] 2. Reduce loss and pollution: Reducing the material transfer link effectively reduces the risk of material loss, while avoiding the pollution that may be introduced during the transfer process, which helps to improve the quality of methyl thiophanate products.

[0015] 3. Cost saving: The integrated design reduces equipment investment and floor space, reduces the production cost of the enterprise, and improves resource utilization.

[0016] 4. Effective solid-liquid separation: The first rotating motor drives the washing tank and the filter cylinder to rotate as a whole through the pulley and the transmission belt, and uses centrifugal force to throw out the water in the wet material, so that the solid material remains in the filter cylinder, and the liquid enters the interlayer between the washing tank and the filter cylinder, realizing efficient solid-liquid separation.

[0017] 5. Prevent material from sticking: When discharging solid materials, the second rotating motor drives the stirring shaft to rotate, and then drives the scraper to scrape the inner wall of the filter cylinder, effectively preventing the material from sticking to the inner wall of the filter cylinder and being unable to be discharged, ensuring that the solid material can be discharged smoothly from the solid discharge port.

[0018] 6. Energy-saving design: The scraper is installed on the horizontal moving frame and its horizontal movement is controlled by the hydraulic cylinder. During the movement of the scraper, the third gear moves along the rack to drive the scraper to deflect 90 degrees, ensuring that the scraper is tangent to the stirring direction during stirring, thereby being subject to less resistance, reducing the load of the second rotating motor during washing and stirring, and saving more energy.

[0032] The methyl thiophanate material to be washed is smoothly added into the filter cartridge 2 through the funnel-shaped material adding port 101, and an appropriate amount of washing liquid is added at the same time. A first gear 204 is fixed to the top of the stirring shaft 201, and a second rotating motor 203 is fixed to the top of the filter cartridge 2. A second gear 2031 is fixed to the output shaft of the second rotating motor 203, and the second gear 2031 is meshed with the first gear 204. Turning on the second rotating motor 203 can drive the second gear 2031 to rotate, and the second gear 2031 is meshed with the first gear 204 to drive the stirring shaft 201 to rotate. The material and the washing liquid are fully stirred by the stirring branch 202, so that the impurities in the material are fully dissolved in the washing liquid. According to the properties of the material and the washing requirements, the stirring speed can be controlled by adjusting the rotation speed of the second rotating motor 203.

[0033] After washing is completed, the liquid discharge port 103 is opened to discharge the washing liquid. A first rotating motor 301 is fixedly installed on the bracket 3. A pulley 302 is fixed to the output shaft of the first rotating motor 301. A transmission belt 303 is provided between the pulley 302 and the outside of the washing tank 1. By turning on the first rotating motor 301, the washing tank 1 and the filter cartridge 2 can be driven to rotate as a whole. Through centrifugal force, the moisture of the wet material is thrown out and enters the interlayer between the washing tank 1 and the filter cartridge 2.
