A dust removal device and method for polyurethane catalyst processing

Abstract

This invention relates to the field of catalyst processing technology, specifically to a dust removal device and method for polyurethane catalyst processing; it includes a support frame, a dust removal box, a dust removal fan, and a bulk material feeding unit. The bulk material feeding unit includes a mounting plate, a rotating ring, a rotating assembly, a threaded rod, a bearing seat, a feed hopper, a bellows, a bulk material box, and a vibration motor. Starting the vibration motor causes the bulk material box to vibrate inside the dust removal box, thereby conveying the dispersed polyurethane catalyst into the material passage through the discharge hole. Simultaneously, starting the rotating assembly drives the rotating ring to rotate on the mounting plate, causing the threaded rod to rotate inside the rotating ring. This, in turn, drives the feed hopper to slide on the chute via the bearing seat, thereby adjusting the position of the bulk material box. This ensures that the polyurethane catalyst is evenly dispersed into multiple material passages, resulting in more thorough dispersion and improved dust removal efficiency when using the dust removal fan to treat the polyurethane catalyst.

[0005] To achieve the above objectives, the present invention provides a dust removal device for polyurethane catalyst processing, comprising a support frame, a dust removal box, a dust removal fan, and a bulk material feeding unit. The dust removal box is mounted on the support frame, and the interior of the dust removal box is provided with multiple air chambers.

The top cross-section of each air chamber is arranged in an equilateral triangle structure. A material discharge pipe is provided at the bottom of the dust removal box.

[0006] The bulk material feeding unit includes a mounting plate, a rotating ring, a rotating assembly, a threaded rod, a bearing seat, a feeding hopper, a bellows, a bulk material box, and a vibrating motor. A chute is provided at the top of the dust collector box, and the feeding hopper is slidably disposed within the chute. The mounting plate is also fixedly mounted at the top of the dust collector box. The rotating ring is rotatably connected to the mounting plate, and the threaded rod is threadedly connected internally to the rotating ring. The bearing seat is mounted on the side of the feeding hopper closest to the mounting plate, and the end of the threaded rod closest to the feeding hopper is inserted into the bearing seat. The rotating assembly is also provided on the mounting plate. A transmission gear is provided on the outside of the rotating ring, and the output end of the rotating assembly is mechanically driven by the transmission gear. The bellows is located at the end of the feeding hopper inside the dust collector box, and the bulk material box is located at the end of the bellows away from the feeding hopper. The vibrating motor is mounted on the bulk material box, and multiple discharge holes are provided at the bottom of the bulk material box.

[0007] The rotating assembly includes a servo motor, an output shaft, and an output gear. The servo motor is mounted on the mounting plate, and the output shaft is provided at the output end of the servo motor. The output gear is provided at the end of the output shaft away from the servo motor, and the output gear meshes with the transmission gear.

[0008] The feed hopper has limit plates on both sides, and the chute has limit grooves on both sides inside, with the limit plates and limit grooves being adapted to each other.

[0009] The corrugated pipe includes a pipe body, a first connecting ring, and a second connecting ring. The first connecting ring is provided at one end of the pipe body, and the second connecting ring is provided at the other end of the pipe body.

[0010] The dust removal device for polyurethane catalyst processing also includes two spring components. The feed hopper is located on both sides inside the dust removal box, and a spring component is provided between each connecting plate and the bulk material box. The two spring components are located on both sides of the corrugated pipe.

[0011] Each of the spring components includes a first connecting block, a spring body, and a second connecting block. The first connecting block is provided at one end of the spring body, and the second connecting block is provided at the other end of the spring body. The first connecting block is detachably connected to the connecting plate, and the second connecting block is detachably connected to the bulk material box.

[0012] The present invention also provides a dust removal method for polyurethane catalyst processing, applied to the dust removal device for polyurethane catalyst processing as described above, the steps of which are as follows:

[0013] The polyurethane catalyst raw material enters the interior of the bulk material box through the feed hopper and the corrugated pipe. The vibration motor is started, causing the bulk material box to vibrate inside the dust collector box.

[0014] During the shaking process, the polyurethane catalyst in the bulk material box is conveyed into the material passage through the discharge hole after dispersion.

[0015] When the dispersed polyurethane catalyst is conveyed into the material channel through the discharge hole, the rotating component is activated, which drives the rotating ring to rotate on the mounting plate, so that the threaded rod is screwed into the inside of the rotating ring, thereby driving the feed hopper to slide on the chute through the bearing seat, thereby adjusting the position of the distribution box, so that the polyurethane catalyst is evenly dispersed into multiple material channels, making the polyurethane catalyst disperse more thoroughly.

[0016] When the polyurethane catalyst is conveyed in the material passage, the dust removal fan is started, and air is blown into the interior of the multiple air chambers through the main air outlet pipe and multiple air outlet branch pipes. The compressed air is blown out through the dust removal holes, thereby removing the dust adhering to the surface of the polyurethane catalyst and completing the dust removal treatment of the polyurethane catalyst.

[0017] This invention discloses a dust removal device and method for processing polyurethane catalysts. The polyurethane catalyst raw material enters the interior of a bulk material box through the feed hopper and the corrugated pipe. The vibration motor is activated, causing the bulk material box to vibrate inside the dust removal box, thereby conveying the dispersed polyurethane catalyst into the material passage through the discharge hole. While conveying the dispersed polyurethane catalyst into the material passage through the discharge hole, the rotating assembly is activated, driving the rotating ring to rotate on the mounting plate. This causes the threaded rod to rotate inside the rotating ring, thereby driving the feed hopper to slide on the chute through the bearing seat, thus adjusting the position of the bulk material box. This ensures that the polyurethane catalyst is evenly dispersed into multiple material passages, resulting in more thorough dispersion and better dust removal effect when using the dust removal fan to treat the polyurethane catalyst.

Compressed air is blown out through the dust removal holes 123, thereby removing the dust attached to the surface of the polyurethane catalyst and completing the dust removal treatment of the polyurethane catalyst.

Since the output gear 115 meshes with the transmission gear 126, the rotating ring 105 is driven to rotate on the mounting plate 104.

[0035] Meanwhile, limit plates 128 are provided on both sides of the feed hopper 109, and limit grooves 129 are provided on both sides of the interior of the slide 125.

The feed hopper 109 is driven to slide on the slide groove 125 via the bearing seat 108, thereby adjusting the position of the bulk material box 111 so that the polyurethane catalyst is evenly dispersed into the multiple material passages 120, making the polyurethane catalyst disperse more thoroughly. When the polyurethane catalyst is conveyed in the material passages 120 inside the dust removal box 102, the dust removal fan 103 is started, and air is blown into the multiple air chambers 119 through the main air outlet 121 and multiple air outlet branch pipes 122. Compressed air is blown out through the dust removal hole 123, thereby removing the dust attached to the surface of the polyurethane catalyst and completing the dust removal treatment of the polyurethane catalyst.

By setting the telescopic baffles 301, some dust is prevented from being scattered out of the dust collector 102 through the chute 125 when compressed air is blown out of the dust collector 102, so that the scattered dust will not cause harm to the health of the workers.

[0048] The telescopic baffle 301 is provided with a first fixing plate 303 at one end and a second fixing plate 304 at the other end. The first fixing plate 303 is detachably connected to the feed hopper 109, and the second fixing plate 304 is detachably connected to the end of the slide chute 125. The first fixing plate 303 is installed on the feed hopper 109 using screws, and the second fixing plate 304 is installed on the end of the slide chute 125 using screws, thereby completing the installation of the telescopic baffle 301.

[0050] Please see Figure 8 The present invention also provides a dust removal method for polyurethane catalyst processing, applied to the dust removal device for polyurethane catalyst processing as described above, the steps of which are as follows:

[0051] S1: The polyurethane catalyst raw material enters the interior of the bulk material box 111 through the feed hopper 109 and the corrugated pipe 110. The vibration motor 112 is started, causing the bulk material box 111 to vibrate inside the dust removal box 102.

[0052] S2: During the shaking process, the polyurethane catalyst in the bulk material box 111 is conveyed into the material passage 120 through the discharge hole 127 after dispersion.

[0053] S3: When the dispersed polyurethane catalyst is conveyed into the feed channel 120 through the discharge hole 127, the rotating assembly 106 is started, which drives the rotating ring 105 to rotate on the mounting plate 104, so that the threaded rod 107 rotates inside the rotating ring 105, thereby driving the feed hopper 109 to slide on the slide groove 125 through the bearing seat 108, thereby adjusting the position of the distribution box 111, so that the polyurethane catalyst is evenly dispersed into multiple feed channels 120, making the polyurethane catalyst disperse more thoroughly;

[0054] S4: When the polyurethane catalyst is conveyed in the material passage 120, the dust removal fan 103 is started, and air is blown into the interior of the multiple air chambers 119 through the main air outlet 121 and multiple branch air outlets 122. The compressed air is blown out through the dust removal hole 123, thereby removing the dust attached to the surface of the polyurethane catalyst and completing the dust removal treatment of the polyurethane catalyst.

[0055] In this embodiment, the polyurethane catalyst raw material enters the bulk material box 111 through the feed hopper 109 and the corrugated pipe 110. The vibration motor 112 is activated, causing the bulk material box 111 to vibrate inside the dust collector 102, thereby conveying the dispersed polyurethane catalyst into the material passage 120 through the discharge hole 127. While conveying the dispersed polyurethane catalyst into the material passage 120 through the discharge hole 127, the rotating assembly 106 is activated, driving the rotating ring 105 to rotate on the mounting plate 104, causing the threaded rod 107 to screw into the rotating ring 105. The bearing seat 108 drives the feed hopper 109 to slide on the chute 125, thereby adjusting the position of the distribution box 111. This ensures that the polyurethane catalyst is evenly dispersed into the multiple material channels 120, resulting in more thorough dispersion. While the polyurethane catalyst is being conveyed within the material channels 120, the dust removal fan 103 is activated, blowing air into the multiple air chambers 119 through the main exhaust pipe 121 and multiple branch exhaust pipes 122. Compressed air is then blown out through the dust removal holes 123, removing dust adhering to the surface of the polyurethane catalyst and completing the dust removal process.
