Technical Field

[0001] This utility model relates to the field of polyurethane adhesive filtration technology, specifically a filtration device for polyurethane adhesive production. Background Technology

[0002] Polyurethane adhesives are an important component of the rapidly developing polyurethane resin industry. They possess excellent properties and are widely used in many fields. Polyurethane adhesives have excellent shear strength and impact resistance, making them suitable for various structural bonding applications, and they also have excellent flexibility.

[0003] Chinese patent CN215310588U discloses a filtration device for the production of polyurethane adhesives. The device includes a body with a cover, to which sandpaper is adhered. The body has an annular groove with a turntable. The turntable has several circular holes, each with a placement plate. A gear ring is fixed to the placement plate. A fixed bracket is attached to the body, and a gear is fixed to the bracket. A rotating motor is installed below the body. The cover has a ramp. This grinding device for the production of vortex discs in automotive air conditioning compressors can continuously grind vortex discs, improving production efficiency and achieving good grinding results. It can grind vortex discs of different specifications, expanding the applicability of the grinding device.

[0004] However, it still has the following drawbacks: the device directly introduces the polyurethane adhesive into the first and second chambers for filtration, but relies solely on the weight of the polyurethane adhesive for the filter to work, resulting in slow efficiency. Therefore, we propose a filtration device for polyurethane adhesive production to address this problem. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Please see Figures 1-5 The present invention provides a technical solution: a filtration device for the production of polyurethane adhesive, comprising a tank 1, a filtration device 2 disposed inside the tank 1, and the filtration device 2 comprising an installation part 21.

[0025] The mounting part 21 includes a hydraulic rod 211, a top plate 213, a housing 214, a filter screen 215, a cleaning brush 216, a limiting ring 219, a mounting cylinder 201, and a bracket 202. The top surface of the output rod of the hydraulic rod 211 is fixedly connected to the bottom surface of the top plate 213. A through hole is opened on the outer surface of the housing 214. The outer surface of the filter screen 215 is fixedly connected to the inner wall of the housing 214. The mounting cylinder 201 is slidably sleeved on the outer surface of the bracket 202. The outer surface of the mounting cylinder 201 is fixedly connected to the outer surface of the cleaning brush 216.

The top outer surface of the limiting ring 219 extends into the limiting ring groove and is slidably connected to the inner wall of the limiting ring groove. The mounting part 21 also includes a fixing block 212, a limiting block 217, a screw 218, and a spring 210.

[0026] The outer surface of the screw 218 rotates through the bearing, passes through the outer surface of the limiting ring 219, and extends into the inside of the limiting ring 219. The limiting block 217 is threaded onto the outer surface of the screw 218. A limiting hole is opened on the outer surface of the housing 214. The outer surface of the limiting block 217 extends into the limiting hole. The bottom surface of the hydraulic rod 211 is fixedly connected to the outer surface of the fixing block 212.

[0027] The front end of the spring 210 is fixedly connected to the back of the bracket 202, and the rear end of the spring 210 is fixedly connected to the inner wall of the mounting cylinder 201. By setting up the cleaning brush 216, the spring 210, the mounting cylinder 201 and the bracket 202, the elastic force of the spring 210 causes the outer surface of the cleaning brush 216 to press against the inner wall of the housing 214 and the outer surface of the filter screen 215. When the housing 214 and the filter screen 215 rotate, the cleaning brush 216 pushes the impurities to the bottom of the housing 214, which facilitates the polyurethane adhesive to be thrown out of the housing 214.

[0028] The tank body 1 is equipped with a drive unit 22;

[0029] The drive unit 22 includes a motor 221, a connecting rod 222, and an arc-shaped scraper 223. The top surface of the motor 221 is fixedly connected to the bottom surface of the tank 1.

The motor 221 drives the housing 214 to rotate, and the polyurethane adhesive is thrown out by centrifugal force, thereby improving the filtration efficiency of the device.

[0031] The outer surface of the arc plate 224 is fixedly connected to the outer surface of the output shaft of the motor 221, the bottom surface of the arc plate 224 is slidably connected to the inner wall of the tank 1, the outer surface of the connecting rod 222 is fixedly connected to the outer surface of the output shaft of the motor 221, and the outer surface of the arc scraper 223 is slidably connected to the inner wall of the tank 1. By setting the connecting rod 222, the arc scraper 223 and the arc plate 224, the polyurethane adhesive is thrown onto the inner wall of the tank 1, the arc scraper 223 scrapes off the polyurethane adhesive adhering to the inner wall of the tank 1, and the arc plate 224 pushes the polyurethane adhesive into the discharge pipe for discharge.

[0032] In use, the polyurethane adhesive is introduced into the housing 214, and the motor 221 is started. The output shaft of the motor 221 drives the locking block 226 to rotate. The locking block 226, along with the limiting cylinder 225 and the housing 214, rotates, using centrifugal force to throw out the polyurethane adhesive. The output shaft of the motor 221 drives the connecting rod 222 and the arc-shaped scraper 223 to rotate. The arc-shaped scraper 223 scrapes off the polyurethane adhesive adhering to the inner wall of the tank 1. The output shaft of the motor 221 drives the arc-shaped plate 224 to rotate. The arc-shaped plate 224 pushes the polyurethane adhesive into the discharge pipe for discharge. After cleaning, the hydraulic rod 211 is extended. The output rod of the hydraulic rod 211 drives the top plate 213 and the housing 214 to move upward. The screw 218 is rotated, and the screw 218 drives the limiting block 217 to move, allowing the housing 214 to be removed for cleaning.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
