Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1 - Figure 5 As shown, a dehydration device for producing polyurethane raw materials for shoes includes a tank 1, and a flushing mechanism 2 is provided inside the tank 1.
[0026] The flushing mechanism 2 includes a water spray box 201 rotatably connected to the inner top wall of the tank 1. An external gear 202 is fixedly installed on the top of the water spray box 201. A motor box 203 is fixedly installed on the top of the tank 1. A motor 204 is fixedly installed on the inner side wall of the motor box 203. A gear 205 is rotatably connected to the inner top wall of the tank 1. The gear 205 meshes with the external gear 202. The output end of the motor 204 is connected to the gear 205. The installed motor box 203 is used to protect the motor 204 and prevent the motor 204 from being damaged by external impact.
[0027] Please see Figure 3 and Figure 4 The bottom of the water tank 201 is provided with multiple drainage channels 206. A water spray box 207 is fixedly installed at the bottom of the water tank 201. A water passage channel 208 is provided at the top of the water spray box 207. The water passage channel 208 corresponds to the drainage channel 206. Multiple high-pressure nozzles 209 are fixedly installed on one side of the water spray box 207. The multiple high-pressure nozzles 209 are arranged in an array. The water pipe is connected to the water inlet pipe 211 by hand so that the water pipe can flush water into the interior of the water tank 201. The water is then transported into the interior of the water spray box 207 through the drainage channel 206 and the water passage channel 208. The water is then sprayed through the multiple high-pressure nozzles 209 to flush the inner wall of the tank 1.
[0028] Please see Figure 3 and Figure 4 Two sponge strips 210 are fixedly installed on both sides of the water spray box 207. The two sponge strips 210 are arranged opposite each other and are in contact with the inner wall of the tank 1. When spraying, the motor 204 is started, which drives the gear 205 to rotate, and the external gear 202 is driven to rotate, thereby driving the water spray box 201 to rotate. Because the sponge strips 210 are in contact with the inner wall of the tank 1 and are fixed on both sides of the water spray box 207, the multiple water spray boxes 207 scrape against the tank 1, effectively ensuring the purity of the product.
[0029] Please see Figure 3 and Figure 4 The top of the tank 1 is fixedly connected to a water inlet pipe 211, which is connected to the water spray box 207. To further explain, the water inlet pipe 211 is connected to an external water pipe for water supply.
[0030] A filtration mechanism 3 is provided on one side of the tank body 1. The filtration mechanism 3 includes multiple filter screens 308 for filtration.
[0031] Please see Figure 5The filtration mechanism 3 includes a conveying pipe 301 fixedly connected to one side of the tank body 1. The other end of the conveying pipe 301 is fixedly connected to a bellows 302. A motor frame 303 is fixedly installed on the inner wall of the bellows 302. An exhaust fan 312 is fixedly installed on the top of the motor frame 303. The bellows 302 is connected to the tank body 1. By starting the exhaust fan 312, the steam generated at high temperature inside the tank body 1 is extracted through the conveying pipe 301 and then filtered through multiple filter screens 308 to purify the harmful gases inside. The purified gases are then discharged through the air outlet slot 310 to avoid the direct discharge of harmful gases.
[0032] Please see Figure 5 A filter box 305 is fixedly installed at the bottom of the air box 302. A vent 304 is provided at the bottom of the air box 302. The air box 302 is connected to the filter box 305 through the vent 304. A pull-out groove 306 is provided on the front side of the filter box 305. A sliding frame 307 is slidably connected inside the pull-out groove 306. A handle 309 is fixedly installed on the front side of the sliding frame 307. The filter screen 308 is detachably connected to the inside of the sliding frame 307. By manually holding the handle 309 and pulling it forward, the sliding frame 307 is moved to slide inside the pull-out groove 306, thereby pulling out the sliding frame 307 to replace the filter screen 308 inside, thus preventing the filter screen 308 from becoming clogged due to prolonged use.
[0033] Please see Figure 5 The filter box 305 has an air outlet slot 310 on one side. A baffle 311 is fixedly installed inside the air outlet slot 310. The air outlet slot 310 is used to discharge the purified air, and the baffle 311 is used to seal the air outlet slot 310 to prevent dust from entering the interior of the filter box 305.
[0034] The tank 1 is also equipped with a collection mechanism 4, which includes a funnel 42 for collecting water.
[0035] Please see Figure 3 The collection mechanism 4 includes a draining net 41 fixedly installed on the inner wall of the tank 1. Multiple support columns 43 are fixedly installed on the inner wall of the tank 1. A funnel 42 is fixedly installed inside the tank 1, located below the draining net 41. A drain pipe 44 is fixedly installed at the bottom of the funnel 42, extending to the outside of the tank 1. The multiple support columns 43 are used to support the funnel 42 and prevent it from falling off. The drain pipe 44 is used to discharge the collected water. The draining net 41 is used to drain the raw materials.
[0036] Please see Figure 2A protective cover 5 is fixedly installed on the outer wall of the tank body 1. Multiple heating tubes 6 are fixedly installed inside the protective cover 5. The multiple heating tubes 6 are in contact with the tank body 1. The protective cover 5 is used to protect the multiple heating tubes 6, prevent them from being damaged by external impacts, and also prevent workers from accidentally touching them and getting burned.
[0037] The implementation principle of this application is as follows: The installed motor box 203 protects the motor 204 from damage caused by external impacts. Water is manually connected to the inlet pipe 211, allowing water to flow into the spray tank 201. The water then passes through the drain trough 206 and the water channel 208, transporting it into the spray box 207. Multiple high-pressure nozzles 209 spray the water, thus rinsing the inner wall of the tank 1. Simultaneously, the motor 204 is activated, driving the gear 205 to rotate, thus linking... The external gear 202 rotates, thereby driving the water spray box 201 to rotate. Because the sponge strip 210 contacts the inner wall of the tank 1 and is fixed to both sides of the water spray box 207, multiple water spray boxes 207 rub against the tank 1, preventing residual polyurethane resin and other impurities from adhering to the inner wall of the tank 1, effectively ensuring product quality. Further explanation: the water inlet pipe 211 is connected to an external water pipe for water supply. By starting the exhaust fan 312, the steam generated at high temperature inside the tank 1 is transported through the delivery pipe... The air is extracted at 301 and filtered through multiple filters 308 to purify the internal harmful gases before being discharged through the air outlet 310, preventing direct emission of harmful gases. Additionally, by manually pulling the handle 309 forward, the sliding frame 307 slides within the pull-out slot 306, allowing it to be pulled out for replacement of the internal filters 308, preventing clogging due to prolonged use. The purified air is then discharged through the installed air outlet 310. The installed baffle net 311 is used to seal the air outlet duct 310 to prevent dust from entering the interior of the filter box 305. The installed multiple support columns 43 are used to support the funnel 42 to prevent the funnel 42 from falling off. The installed drain pipe 44 is used to centrally discharge the collected water. The installed drain net 41 is used to drain the raw materials. The installed protective cover 5 is used to protect the multiple heating tubes 6 from external impacts and damage, and also to prevent workers from accidentally touching them and getting burned.
