Description

Technical Field

[0001] This invention relates to the field of chloroprene rubber dehydration technology, and more specifically, to an industrial dehydration device and system for powdered chloroprene rubber. Background Technology

[0002] Chloroprene rubber powder, commonly known as chloroprene rubber, is a synthetic rubber with excellent oil resistance, heat resistance, aging resistance, and superior oxidation and chemical corrosion resistance. It is mainly obtained by the polymerization reaction of chloroprene monomer and is widely used in many fields such as automobiles, industry, electronics, footwear, and construction. Chloroprene monomer is usually polymerized by emulsion polymerization or solution polymerization. Similar to butadiene, the polymerization reaction of chloroprene involves free radical initiators and other auxiliary chemicals to produce emulsion-like chloroprene rubber, which is then processed into chloroprene rubber powder through washing and drying processes.

[0018] An industrial dehydration system for powdered chloroprene rubber, applicable to the aforementioned industrial dehydration device for powdered chloroprene rubber, includes the following steps:

[0019] S1: Primary dehydration; The rubber granules to be dehydrated are fed into the tank from the feed hopper. The first motor drives the first rotating shaft to rotate, and under the meshing of the first gear ring and the tooth groove, the filter cylinder rotates synchronously to centrifuge and dehydrate the rubber. By driving the material leaf to rotate in the opposite direction, the rubber fed from the feed hopper is thrown against the inner wall of the filter cylinder to avoid the rubber from accumulating.

[0020] S2: Secondary dehydration; After the rubber is initially dehydrated by the filter cylinder, the centrifugal disc is moved downward by the drive shaft of the electric telescopic rod. The first gear ring disengages from the tooth groove, so that the first gear ring meshes with the third gear. Under the action of centrifugal force, the rubber on the surface of the centrifugal disc is thrown towards the side wall of the rotating ring, and under the action of the arc blades, the rubber is thrown upward. The hot air blower works to inject hot air into the cavity and spray it out from the nozzle onto the surface of the thrown rubber for secondary dehydration.

[0021] S3: Three-stage dehydration; The second motor drives two pressure rollers to rotate in opposite directions, performing a third dehydration on the rubber that has completed the second dehydration. At the same time, it drives the cleaning roller to rotate synchronously, cleaning the rubber residue on the surface of the pressure roller and wiping away the water stains on the surface of the pressure roller. The cleaning roller drives the protrusion to rotate synchronously, and with the cooperation of the spring, it drives the connecting rod to drive the feeding plate to swing back and forth, preventing rubber from accumulating on the surface of the feeding plate.

[0022] The present invention provides an industrial dehydration device and system for powdered chloroprene rubber, the beneficial effects of which include:

[0023] By setting up a primary dewatering mechanism, the first motor drives the first rotating shaft to rotate, which in turn drives the centrifugal disc to rotate synchronously through the spline teeth and spline grooves. Under the meshing of the first gear ring and the gear groove, the filter cylinder is driven to rotate synchronously to centrifuge and dewater the rubber. When the first motor drives the first rotating shaft to rotate, the second gear drives the first gear and the material dispensing blade to rotate in opposite directions, thereby causing the rubber fed from the feed hopper to be thrown against the inner wall of the filter cylinder in the opposite direction, preventing the rubber from accumulating and improving the dewatering effect.

[0024] 2. By setting up a secondary dehydration mechanism, the centrifugal disc is moved downward by the drive shaft of the electric telescopic rod. The first gear ring disengages from the tooth groove, allowing the first gear ring to mesh with the third gear. This drives the second gear ring to rotate the rotating ring. Under the action of centrifugal force, the rubber on the surface of the centrifugal disc is thrown towards the side wall of the rotating ring. Under the action of the arc blades, the rubber is thrown upward. The electric telescopic rod drives the centrifugal disc to move downward, causing the first gear ring to mesh with the third gear. This causes the second base plate to descend synchronously, making the second contact point connect with the first contact point. Then the hot air blower starts working, injecting hot air into the cavity and spraying it out of the nozzle onto the surface of the thrown rubber, performing secondary dehydration on the rubber and improving the dehydration efficiency.

[0025] 3. By setting up a three-stage dewatering mechanism, the second motor can drive two pressure rollers to rotate in opposite directions, performing a third dewatering on the rubber that has completed the second dewatering, thereby improving the dewatering efficiency. At the same time, the fifth gear drives the cleaning roller to rotate synchronously, cleaning the rubber residue on the surface of the pressure roller and wiping away the water stains on the surface of the pressure roller, ensuring the dewatering effect. The cleaning roller drives the protrusion to rotate synchronously, and with the cooperation of the spring, drives the connecting rod to drive the feeding plate to swing back and forth, avoiding the accumulation of rubber on the surface of the feeding plate and ensuring the feeding speed.

The cleaning roller 806 drives the protrusion 807 to rotate synchronously, and with the cooperation of the spring 813, drives the connecting rod 808 to drive the feeding plate 805 to swing back and forth, preventing rubber from accumulating on the surface of the feeding plate 805 and ensuring the feeding speed.

[0048] Specifically, the working principle of this industrial dewatering device for powdered chloroprene rubber is as follows: During use, the rubber particles to be dewatered are fed into the tank 2 from the feed hopper 3. The first motor 603 drives the first rotating shaft 602 to rotate. The spline teeth 608 and spline grooves 609 drive the centrifugal disc 605 to rotate synchronously. Under the meshing of the first gear ring 606 and gear groove 607, the filter cylinder 601 is driven to rotate synchronously to centrifuge and dewater the rubber. When the first motor 603 drives the first rotating shaft 602 to rotate, the second gear 616 drives the first gear 615 and the material dispensing blade 614 to rotate in the opposite direction, thereby causing the rubber fed from the feed hopper 3 to be thrown against the inner wall of the filter cylinder 601 in the opposite direction, preventing the rubber from accumulating and improving the dewatering effect.

[0049] After the rubber undergoes initial dehydration through the filter cylinder 601, the electric telescopic rod 612 drives the sleeve shaft 604 to move the centrifugal disc 605 downward. The first gear ring 606 disengages from the tooth groove 607, allowing the first gear ring 606 to mesh with the third gear 706. This drives the second gear ring 704 to rotate the rotating ring 702. Under the action of centrifugal force, the rubber on the surface of the centrifugal disc 605 is thrown towards the side wall of the rotating ring 702. Under the action of the arc-shaped blade 703, the rubber is thrown upward. The electric telescopic rod 612 drives the centrifugal disc 605 downward, causing the first gear ring 606 to mesh with the third gear 706. This causes the second base plate 709 to descend synchronously, making the second contact 710 and the first contact 708 connected. Then, the hot air blower 714 starts working, injecting hot air into the cavity 712 and spraying it out from the nozzle 713 onto the surface of the thrown rubber, performing secondary dehydration on the rubber and improving the dehydration efficiency.

[0050] The second motor 803 drives the two pressure rollers 802 to rotate in opposite directions, performing a third dehydration on the rubber that has completed the second dehydration, thereby improving the dehydration efficiency. At the same time, the fifth gear 814 drives the cleaning roller 806 to rotate synchronously, cleaning the rubber residue on the surface of the pressure roller 802 and wiping away the water stains on the surface of the pressure roller 802, ensuring the dehydration effect. The cleaning roller 806 drives the protrusion 807 to rotate synchronously, and with the cooperation of the spring 813, drives the connecting rod 808 to drive the feeding plate 805 to swing back and forth, preventing rubber from accumulating on the surface of the feeding plate 805 and ensuring the feeding speed.

[0051] An industrial dehydration system for powdered chloroprene rubber, applicable to the aforementioned industrial dehydration device for powdered chloroprene rubber, includes the following steps:

[0052] S1: Primary dehydration; The rubber granules to be dehydrated are fed into the tank 2 from the feed hopper 3. The first motor 603 drives the first rotating shaft 602 to rotate, and under the meshing of the first gear ring 606 and the tooth groove 607, the filter cylinder 601 is driven to rotate synchronously to centrifuge and dehydrate the rubber. By driving the material dispersing blade 614 to rotate in the opposite direction, the rubber fed from the feed hopper 3 is thrown against the inner wall of the filter cylinder 601 to avoid the rubber from accumulating.

[0053] S2: Secondary dehydration; After the rubber is initially dehydrated by the filter cylinder 601, the electric telescopic rod 612 drives the sleeve shaft 604 to move the centrifugal disc 605 downward. The first gear ring 606 disengages from the tooth groove 607, so that the first gear ring 606 meshes with the third gear 706. Under the action of centrifugal force, the rubber on the surface of the centrifugal disc 605 is thrown towards the side wall of the rotating ring 702, and under the action of the arc blade 703, the rubber is thrown upward. The hot air blower 714 works to inject hot air into the cavity 712 and spray it out from the nozzle 713 onto the surface of the thrown rubber for secondary dehydration.

[0054] S3: Three-stage dehydration; the second motor 803 drives the two pressure rollers 802 to rotate in opposite directions, performing a third dehydration on the rubber that has completed the second dehydration. At the same time, it drives the cleaning roller 806 to rotate synchronously, cleaning the rubber residue on the surface of the pressure roller 802 and wiping away the water stains on the surface of the pressure roller 802. The cleaning roller 806 drives the protrusion 807 to rotate synchronously, and with the cooperation of the spring 813, it drives the connecting rod 808 to drive the feeding plate 805 to swing back and forth, preventing rubber from accumulating on the surface of the feeding plate 805.
