Technical Field
[0001] This utility model belongs to the field of plastic modified material production technology, and relates to a pre-mixing device for plastic modified materials. Background Technology
[0002] Plastic modified materials are high-performance materials that are innovatively modified through physical or chemical means to enhance the performance, expand the functions, or reduce the production cost of plastics. In the production process of plastic modified materials, the pre-mixing device plays a crucial role. Its main function is to uniformly mix various raw materials (such as resins, fillers, toughening agents, modifiers, etc.) according to a strict formula, thereby ensuring the stability and consistency of material properties in subsequent processing stages.
[0003] Due to the unique properties of modified plastic materials, certain chemical reactions may occur during the mixing process, generating dust and harmful volatile substances. Within the enclosed mixing chamber, these dust and volatile substances are difficult to remove in a timely manner and are ultimately released along with the modified plastic materials, potentially impacting the health of surrounding workers and posing a potential hazard to the natural environment. Therefore, there is an urgent need for a pre-mixing device for modified plastic materials to address these issues. Utility Model Content

Dust hoods 304 are connected to and communicate with the top of the outer walls on both sides of the mixing tank 2, and the other end of the dust hood 304 is flush with the inner wall of the mixing tank 2. The air outlet of the pump 307 is connected to a duct 310, and the other end of the duct 310 is located at the bottom of the interior of the processing tank 3. The interior of the processing tank 3 is filled with water, and a water inlet 309 is connected to the top side of the processing tank 3. A drain outlet 308 is connected to the bottom of the outer wall of one end of the processing tank 3, and both the drain outlet 308 and the water inlet 309 are equipped with valves. Filter screens 305 are fixed to the inner walls of the two dust hoods 304 that are close to each other. Support rings 303 are fixed to both sides of the outer wall of the conveying pipe 302, and the other end of the support rings 303 is fixed to the outer wall of the mixing tank 2. A fixing plate 301 is fixed to the bottom of the outer wall of one end of the mixing tank 2. Support legs 3010 are fixed to both sides of the bottom of the fixing plate 301, and the bottom of the two support legs 3010 is fixed to the top of the base 1. The bottom of the processing tank 3 is fixed to the top of the fixing plate 301. A filter box 4 is provided at the top end of the processing tank 3. A connecting pipe 401 is connected to the bottom of the filter box 4. The other end of the connecting pipe 401 is connected to the top of the processing tank 3 and communicates with its interior. An activated carbon layer 404 is installed on the bottom of the inner wall of the filter box 4. An adsorption layer 405 is fixed to the top of the inner wall of the filter box 4. A vent 403 is connected to the top of the filter box 4. Fixing columns 402 are fixed to both sides of the bottom of the filter box 4, and the bottom of the fixing columns 402 is fixed to the top of the processing tank 3. The mixing tank 2 is equipped with a stirring mechanism for stirring materials. The mixing mechanism includes a rotating rod 203 rotatably connected to the top of the inner wall of the mixing tank 2. Multiple mixing rods 205 are fixed to the outer wall of the rotating rod 203. A motor 204 is mounted on the top of the mixing tank 2, and the output shaft of the motor 204 is fixedly connected to the top of the rotating rod 203. Connecting plates 5 are fixed to the top and bottom of the outer wall of the rotating rod 203. Scrapers 501 are fixed to both ends of the two connecting plates 5, and the scrapers 501 are in contact with the inner wall of the mixing tank 2. Two feed inlets 202 communicating with the interior are located at both ends of the top of the mixing tank 2, and a discharge outlet 201 is connected to the bottom of the mixing tank 2. A control valve is installed inside the discharge outlet 201.
[0028] The working principle of this utility model is as follows: In use, materials are first fed into the mixing tank 2 through the discharge port 201. Then, the motor 204 is started, which drives the rotating rod 203 to rotate. The rotating rod 203 drives several stirring rods 205 on the outer wall to rotate, and the stirring rods 205 stir and mix the materials inside the mixing tank 2. When the rotating rod 203 rotates, it drives the connecting plate 5 to rotate, and the connecting plate 5 drives the scrapers 501 at both ends to rotate. The scrapers 501 scrape off the materials adhering to the inner wall of the mixing tank 2. Since the filter screen 305 and the dust collection hood 304 are flush with the inner wall of the mixing tank 2, the scrapers 501 scrape the filter screen 305 while scraping the inner wall of the mixing tank 2 to prevent the filter screen 305 from clogging. When the materials are stirred and mixed, some dust and volatiles are generated. At this time, the pump 307 is started, and the pump 307 draws air into the conveying pipe 302 through the connecting pipe 306. The dust and volatiles generated inside the mixing tank 2 are drawn into the processing tank 3 through both ends of the conveying pipe 302. Then, they are introduced into the bottom of the processing tank 3 through the conduit 310. At this time, the dust will mix with water, and the gas will be discharged into the filter box 4 through the connecting pipe 401. The volatiles will then pass through the activated carbon layer 404 and the adsorption layer 405, which will filter and purify the volatiles. The purified gas will then be discharged from the exhaust port 403, thus achieving the effect of protecting the environment and the health of the staff. Opening the valve inside the drain port 308 can drain the water inside the processing tank 3. Then, opening the valve inside the water inlet 309 allows water to be refilled into the processing tank 3. Finally, opening the control valve inside the discharge port 201 allows the mixed material to be discharged.
[0029] In summary, in this invention, the pump 307 draws the dust and volatiles generated inside the mixing tank 2 into the conduit 310 through the conveying pipe 302 and the connecting pipe 306, and then discharges them from the conduit 310 into the bottom of the treatment tank 3. The dust mixes with water, and the volatiles are discharged into the filter box 4 through the connecting pipe 401. The activated carbon layer 404 and the adsorption layer 405 filter and purify the volatiles, thereby achieving the effect of treating dust and volatiles, reducing air pollution, and protecting the health of the workers.
