When the filter box needs to be cleaned, the filter box needs to be disassembled, cleaned, and dried manually before it can be used continuously. The shutdown time of the internal mixer is relatively long, affecting the normal production of rubber and the air purification efficiency. Moreover, when the internal mixer is in use, in order to avoid the internal mixer from getting too hot and affecting the quality of rubber, water cooling or air cooling methods are often used to cool the internal mixer, and the heat generated during the operation of the internal mixer cannot be effectively utilized, resulting in waste of the generated heat.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. A soot treatment component is provided. After the rubber processing is completed, the flue gas generated during processing is directly collected and filtered, and the flue gas will not come into contact with workers during the process, effectively protecting the health of workers. The three filter cores located within two adjacent U-shaped partitions gradually increase in filtering strength along the gas flow direction, enabling effective filtration of the flue gas, with good air purification effect, avoiding soot pollution of the atmosphere. When cleaning the filter cores, the sealing cylinder drives the sealing circular plate to disengage from the separating rings at both ends of the U-shaped partition, and the conversion motor drives the conversion rotating shaft to rotate 180 degrees to replace the original filter box corresponding to the filtering air pump. During the process, the internal mixer does not need to stop for a long time, and the processing efficiency is high. The high-temperature steam generated by the steam generator flows through the steam hose into the space where the filtering air pump is located, and the high-temperature steam is used to clean the filter cores. The high-temperature steam can penetrate into the fine gaps and holes of the filter cores, effectively removing the dirt and impurities hidden therein, and the high temperature of the high-temperature steam can be used to disinfect the filter cores at high temperature, with better cleaning effect;

[0023] The warm water generated by the cooling elbow for cooling the processing hopper of the internal mixer enters the interior of the water storage tank. The steam generator can use the warm water inside the water storage tank. When the steam generator is in use, the initial temperature of the water entering the steam generator is higher, shortening the water heating time and enabling the effective utilization of the warm water generated by cooling;

[0024] After the cleaning of the filter cores is completed, the conversion motor drives the conversion rotating shaft to rotate 90 degrees, and the cleaned and damp filter cores move to the position where the drying air pump is located. The cooling method of the internal mixer is changed from water cooling to air cooling. After the cold air cools the processing hopper, after heat exchange, the formed hot air passes through the hot air joint and the hot air hose into the filter box corresponding to the drying air pump to dry the filter cores inside the filter box, eliminating the need to use a separate dryer for drying. While cooling the internal mixer, the heat generated by it is also recycled, making the equipment more environmentally friendly;

[0025] When the filter cores inside the filter box need to be replaced, when the conversion motor drives a new filter core to replace the filter core to be replaced, remove the fixing screw corresponding to the filter box to be replaced from the fixing screw hole, remove the filter box, then remove the breathable mesh plate, and replace it with a new filter core. It is convenient and fast. During the process, the internal mixer does not need to stop for a long time, and the processing efficiency is even higher.

[0026] 2. A heat energy recovery component is provided. The high-temperature flue gas generated in rubber production first flows through an exhaust hose for a certain section and enters the interior of the heat exchange box. The high-temperature flue gas passes through the gas distribution chamber and gas distribution holes at one end and enters the cavity between the two heat exchange plates, and then enters the interior of the exhaust hose for another section through the gas distribution holes and gas distribution chamber at the other end. The cold air is guided by an air delivery pump and enters the interior of the heat exchange box from the gas distribution box at the bottom. Under the shunting action of the gas distribution ports, it flows through the cavity between the two heat exchange plates, and finally flows through the heat recovery pipe and enters the interior of the heat preservation cylinder. Under the action of heat conduction, the cold air is heated. The heated air wraps around the water storage tank to keep the warm water inside the water storage tank warm, effectively recovering and utilizing the heat in the high-temperature flue gas. The transverse wave strips and longitudinal wave strips can disrupt the flowing gas in the space where they are located, prolong the time of the gas inside the heat exchange box, and have a higher heat exchange efficiency;

[0027] The high-temperature steam mixed with dust enters the interior of the connected steam distribution pipe through the exhaust pipe, and then enters the interior of the U-shaped pipe. The cooling water pump delivers clear water into the U-shaped box, and the clear water cools down the U-shaped pipe. The high-temperature steam mixed with dust condenses into water droplets when it meets the cold. The water droplets mixed with dust flow into the interior of the sewage main pipe through the sewage branch pipe, which is convenient for collecting and treating the sewage. After the cooling water cools down the U-shaped pipe, the cooling water changes from cold water to warm water, and the warm water flowing out of the heat recovery water pipe is sent into the interior of the water storage tank, making full use of the heat generated by the steam and the cooling water, and making the processing of the rubber conveyor belt more environmentally friendly.

[0028] In summary, in the dust treatment component, by flexibly switching between water cooling and air cooling of the internal mixer, while drying the filter element, the heat generated by the internal mixer is also recovered and utilized. In the heat energy recovery component, before the high-temperature flue gas generated in rubber production is filtered, the heat of the flue gas is recovered and utilized through effective heat exchange. The two components cooperate with each other to utilize the heat generated by the self-cooling of the internal mixer and the heat of the flue gas generated after processing, making the overall equipment more environmentally friendly in use.

One side of the top of the heat preservation cylinder 306 is connected to a pressure relief valve 307;

[0058] At both ends inside the heat exchange box 301, there are air distribution plates 308 installed. A gas distribution cavity 309 is formed between the air distribution plates 308 and the inner wall of the heat exchange box 301. On one side of the air distribution plate 308, a number of air distribution holes 310 are evenly penetrated. On one side of the air distribution plate 308, a number of clamping grooves 311 are arranged at equal intervals. The air distribution holes 310 are located in the middle of two adjacent clamping grooves 311. A heat exchange plate 312 is movably embedded in the middle of two opposite clamping grooves 311. On one side of the heat exchange plate 312, a number of transverse wave strips 313 are welded at equal intervals. On the other side of the heat exchange plate 312, a number of longitudinal wave strips 314 are welded at equal intervals. Under the guidance of the filtering air pump 218, the high-temperature flue gas generated by rubber production flows through the exhaust hose 240 at one end and enters the inside of the heat exchange box 301. The high-temperature flue gas passes through the gas distribution cavity 309 and the air distribution holes 310 at one end and enters the cavity between the two heat exchange plates 312, and then enters the inside of the exhaust hose 240 at the other end through the air distribution holes 310 and the gas distribution cavity 309 at the other end, and finally enters the inside of the filter box 206 corresponding to the filtering air pump 218. The cold air enters the inside of the heat exchange box 301 from the air distribution box 302 at the bottom under the guidance of the air delivery pump 303. Under the shunting action of the air distribution port 304, it flows through the cavity between the two heat exchange plates 312, and finally flows through the air distribution box 302 and the heat recovery trachea 305 at the top and enters the inside of the heat preservation cylinder 306. The cavity through which the high-temperature flue gas flows has transverse wave strips 313 inside, and the cavity through which the cold air flows has longitudinal wave strips 314 inside. The heat exchange plate 312 is made of copper material. Under the action of heat conduction, the cold air is heated, and the heat in the high-temperature flue gas is effectively recovered and utilized. The transverse wave strips 313 and the longitudinal wave strips 314 can disrupt the flowing gas in the space where they are located, extend the time of the gas inside the heat exchange box 301, and make the heat exchange efficiency better;

[0059] On one side of the exhaust pipe 220, there is a U-shaped box 315 installed. At both ends inside the U-shaped box 315, there are steam distribution pipes 316 installed. The other end of the exhaust pipe 220 penetrates through the U-shaped box 315 and is connected to one side of the adjacent steam distribution pipe 316. A number of U-shaped pipes 317 are connected at equal intervals between the bottoms of the steam distribution pipes 316. The middle of the bottom of the U-shaped pipe 317 is connected to the top end of one side of the sewage branch pipe 318. The other end of the bottom of the sewage branch pipe 318 is connected to the top of the sewage main pipe 319. On one side of the U-shaped box 315, there is a cooling water pump 320 installed. The water outlet end of the cooling water pump 320 is connected to the bottom of one side of the U-shaped box 315. One end of the top of the U-shaped box 315 is connected to a hot water return pipe 321;

[0060] The input ends of the conversion motor 217, the filtering air pump 218, the drying air pump 221, the steam generator 231, the electric control air valve 238, the air delivery pump 303 and the cooling water pump 320 are electrically connected to the output end of the external power supply through the controller. By controlling each electrical component through the controller, it is convenient to automatically control the equipment.

[0061] Working principle and usage process of the present invention: When feeding materials into the processing hopper 225, the filtering air pump 218 operates, the electric control air valve 238 connected to the dust exhaust hose 239 is opened, and the electric control air valve 238 connected to the exhaust hose 240 is closed. Under the action of pressure, the dust generated during feeding passes through the dust exhaust joint 236, the dust exhaust hose 239, and the three-way pipe 237 and enters the interior of the filter box 206 corresponding to the filtering air pump 218. The filter element 207 filters the dust generated during feeding, ensuring the physical health of on-site workers. When the rubber is processed by the internal mixer, the pressing block of the internal mixer rises. When the pressing block disengages from the interior of the processing hopper 225, the filtering air pump 218 operates, the electric control air valve 238 connected to the exhaust hose 240 is opened, and the electric control air valve 238 connected to the dust exhaust hose 239 is closed. The high-temperature flue gas generated during rubber processing can pass through the exhaust joint 235 and the exhaust hose 240 and enter the interior of the filter box 206 corresponding to the filtering air pump 218, realizing the filtration of the flue gas generated during rubber processing. After the rubber processing is completed, the flue gas generated during processing is directly collected and filtered, and the flue gas will not come into contact with humans during the process. When the processing hopper 225 is opened, the toxic gas has been discharged, effectively ensuring the physical health of workers. Moreover, the filtering intensities of the three filter elements 207 located in the adjacent two U-shaped partitions 202 gradually increase along the gas flow direction, which can effectively filter dust, has a good air purification effect, and avoids smoke and dust pollution of the atmosphere;

[0062] When the high-temperature flue gas generated during rubber production enters the interior of the filter box 206, the high-temperature flue gas will first flow through a section of the exhaust hose 240 and enter the interior of the heat exchange box 301. The high-temperature flue gas passes through the gas distribution cavity 309 and the gas distribution holes 310 at one end and enters the cavity between the two heat exchange plates 312, and then enters the interior of another section of the exhaust hose 240 through the gas distribution holes 310 and the gas distribution cavity 309 at the other end, and finally enters the interior of the filter box 206 corresponding to the filtering air pump 218. The cold air is guided by the air delivery pump 303 and enters the interior of the heat exchange box 301 from the air distribution box 302 at the bottom. Under the diversion action of the air distribution port 304, it flows through the cavity between the two heat exchange plates 312, and finally flows through the air distribution box 302 and the heat recovery pipe 305 at the top and enters the heat preservation cylinder 306. The interior of the cavity through which the high-temperature flue gas flows is the transverse corrugation 313, and the interior of the cavity through which the cold air flows is the longitudinal corrugation 314. The heat exchange plate 312 is made of copper. Under the action of heat conduction, the cold air is heated, and the heated air wraps the water storage tank 229 to keep the warm water in the water storage tank 229 warm, effectively recycling and utilizing the heat in the high-temperature flue gas. The transverse corrugation 313 and the longitudinal corrugation 314 can disrupt the flowing gas in the space where they are located, extend the time of the gas in the heat exchange box 301, and make the heat exchange efficiency higher;

[0063] When the internal mixer is in use, the water outlet end of the external water pump is connected to the water inlet head 227. The external water pump conveys cold water into the cooling elbow 226. Under heat conduction, the processing hopper 225 of the internal mixer is cooled. The warm water generated by the cooling flows through the water outlet head 228 and the inlet hose 230 into the water storage tank 229. The steam generator 231 can use the warm water in the water storage tank 229. When the steam generator 231 is in use, the initial temperature of the water inlet of the steam generator 231 is higher, shortening the water heating time and enabling the effective utilization of the warm water generated by the cooling;

[0064] When the filter element 207 has been used for a period of time and needs to be cleaned, the sealing cylinder 216 is started. The sealing cylinder 216 drives the sealing circular plate 215 to move along the conversion rotating shaft 201, so that the sealing circular plate 215 disengages from the separating rings 203 at both ends of the U-shaped partition plate 202. The conversion motor 217 drives the conversion rotating shaft 201 to rotate 180 degrees, replacing the original filter box 206 corresponding to the filter air pump 218. The new filter element 207 replaces the original old filter element 207. After replacement, the sealing cylinder 216 drives the sealing circular plate 215 to return to its original position, so that the sealing circular plate 215 closely adheres to the adjacent separating ring 203, completing the replacement of the new filter element 207. At this time, the first replaced filter element 207 moves to the position of the filter air pump 218, and the steam generator 231 is started. The high-temperature steam generated by the steam generator 231 flows through the steam hose 232 into the space where the filter air pump 218 is located. The constant pressure valve 219 controls the pressure of the high-temperature steam, so that the high-temperature steam cleans the filter element 207 under a certain pressure;

[0065] Using high-temperature steam to clean the filter element 207, the high-temperature steam can penetrate into the fine gaps and holes of the filter element 207, effectively removing the dirt and impurities hidden therein, with good cleaning effect. Moreover, using the high temperature of the high-temperature steam can disinfect the filter element 207 at high temperature, with good cleaning effect;

[0066] When the pressure exceeds the pressure of the constant pressure valve 219, the high-temperature steam mixed with dust enters the connected steam distribution pipe 316 through the exhaust pipe 220, and then enters the U-shaped pipe 317. The cooling water pump 320 conveys clean water into the U-shaped box 315. The clean water cools the U-shaped pipe 317. The high-temperature steam mixed with dust condenses into water droplets when it meets the cold. The water droplets mixed with dust flow into the sewage main pipe 319 through the sewage branch pipe 318, facilitating the collection and treatment of sewage. After the cooling water cools the U-shaped pipe 317, the cooling water changes from cold water to warm water, and the warm water flowing out of the return hot water pipe 321 is sent into the water storage tank 229, making full use of the heat generated by the steam and the cooling water;

[0067] After the filter element 207 is cleaned, the sealing cylinder 216 drives the sealing circular plate 215 to disengage from the separating rings 203 at both ends of the U-shaped partition plate 202. The conversion motor 217 drives the conversion rotating shaft 201 to rotate by 90 degrees. The cleaned and wet filter element 207 moves to the position where the drying air pump 221 is located. At this time, the external water pump stops delivering cooling water into the cooling elbow 226, and the drying air pump 221 starts, changing the cooling method of the internal mixer from water cooling to air cooling. Under pressure, the cold air passes through the air inlet partition net 241 and enters the space where the processing hopper 225 and the sealing hopper 223 are located. After the cold air cools the processing hopper 225, after heat exchange, the formed hot air passes through the hot air connector 233 and the hot air hose 234 and enters the inside of the filter box 206 corresponding to the drying air pump 221, drying the filter element 207 inside the filter box 206. There is no need to use a separate dryer for drying, and while cooling the internal mixer, the heat generated by it is also recycled, making the equipment more environmentally friendly;

[0068] When the filter element 207 inside the filter box 206 needs to be replaced, when the conversion motor 217 drives the new filter element 207 to replace the filter element 207 to be replaced, take out the fixing screw corresponding to the filter box 206 to be replaced from the fixing screw hole 205, remove the filter box 206, then remove the breathable mesh plate 208, and replace the new filter element 207. It is convenient and fast, and the internal mixer does not need to be shut down for a long time during the process, and the processing efficiency is higher;

[0069] The bottom of the sealing ring 211 is connected through to the liquid collecting box 212. The liquid collecting box 212 is movably embedded with a pumping box 213. The pumping box 213 can collect the water droplets generated when the steam is cooled, preventing the water droplets from remaining inside the separating groove 204 and ensuring the normal operation of the equipment.
