Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, specifically a screw conveyor for processing recycled rubber. Background Technology

[0002] Reclaimed rubber processing refers to the process of turning waste rubber products into usable rubber materials through a series of treatments and processes; the small granular raw materials after crushing and breaking down waste rubber products need to be stably transported to the designated process location;

[0003] According to CN222373640U, a screw conveyor for processing recycled rubber is disclosed. This technology discloses a screw conveyor for processing recycled rubber that includes a frame, a conveyor box, a drive unit, a conveying screw, and a discharge pipe. The conveyor box is hollow inside and open at the top. The bottom of the conveyor box is fixed to the frame and is inclined. The conveying screw is axially fixed inside the conveyor box and can rotate circumferentially. The conveying screw is parallel to the bottom of the conveyor box. The drive unit is fixed inside the conveyor box and connected to the conveying screw. The bottom of the conveyor box at its highest point has a through discharge port. The discharge pipe is fixed to the bottom of the conveyor box and communicates with the discharge port. This technology offers advantages such as: "Due to the large internal capacity of the conveyor box, a large amount of recycled rubber raw material can be conveyed. Its operating efficiency is not only relatively high, but automatic conveying can be achieved simply by placing the recycled rubber raw material into the hopper. It has a high degree of automation and high stability."

[0004] The aforementioned screw conveyor system, when conveying crushed rubber products, suffers from severe particle size mixing due to the lack of a particle size screening device. The unscreened mixture may contain both large 20mm pieces of rubber and fine 0.1mm particles. This mixing of materials with such large particle size differences easily triggers a series of operational problems: large pieces of rubber become stuck in the narrow gap between the screw blades and the housing, while ultrafine particles easily adhere to the inner wall of the conveyor. The combined effect significantly increases conveying resistance and leads to frequent equipment stalls, severely impacting the continuous and stable operation of the production line. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a screw conveyor for processing recycled rubber. By setting up a three-stage screening cylinder to classify and screen rubber particles, it avoids large pieces of rubber from entering the main component and causing blockages. Furthermore, the unqualified rubber after screening is discharged through the discharge pipe, which facilitates recycling or secondary processing and reduces waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screw conveyor for processing recycled rubber, comprising a screw conveyor for conveying rubber, the screw conveyor comprising:

[0007] The main components include a spiral blade that is rotatably installed inside the cylinder, a first motor that is installed at the left end of the cylinder and used to drive the spiral blade, a feed hopper that is fixed on the left side of the upper end of the cylinder, and a discharge port that is fixed on the right side of the lower end of the cylinder.

[0008] The screening assembly includes a bin body fixed to the upper end of the feed hopper. Inside the bin body, a fine screening cylinder, a medium screening cylinder, and a coarse screening cylinder are rotatably installed from left to right, with the fine screening cylinder located directly above the feed hopper. Two discharge pipes are fixed at the bottom of the bin body, with the two discharge pipes located directly below the medium screening cylinder and the coarse screening cylinder, respectively. A drive unit is provided on the bin body to drive the fine screening cylinder, the medium screening cylinder, and the coarse screening cylinder to rotate.

[0009] Preferably, the screening assembly further includes a ramp disposed at the left end of the bin body, and the lower end of the ramp is on the same horizontal line as the axis of the fine screening cylinder.

[0010] Preferably, the driving component includes a second motor fixed at the rear end of the chamber body for driving the fine screening cylinder to rotate. The front ends of the fine screening cylinder, the medium screening cylinder, and the coarse screening cylinder are all fixed with transmission pulleys, and a second belt is installed between adjacent transmission pulleys.

[0011] Preferably, the main component further includes a blade that is rotatably mounted inside the feed hopper.

[0012] Preferably, the main component further includes a driven pulley fixed to the left end of the blade, a driving pulley fixed to the left end of the helical blade, and a first belt installed between the driving pulley and the driven pulley.

[0013] Preferably, the main component further includes a cylinder cover hinged to the upper end of the cylinder, and the front end of the cylinder cover is fixed to the front end of the cylinder by bolts.

[0014] Beneficial effects

[0015] This invention provides a screw conveyor for processing recycled rubber. Compared with the prior art, it has the following advantages:

[0016] 1. Rubber is poured into the silo from the ramp and falls onto the fine screening cylinder. Rubber smaller than the screen openings of the fine screening cylinder falls directly into the feed hopper, while rubber larger than the screen openings is conveyed to the medium screening cylinder. Rubber smaller than the screen openings of the medium screening cylinder is discharged through the discharge pipe on the left side, and rubber larger than the screen openings of the medium screening cylinder is conveyed to the coarse screening cylinder and discharged through the screen openings of the coarse screening cylinder through the discharge pipe on the right side. By setting up three-stage screening cylinders to classify and screen rubber particles, large pieces of rubber are prevented from entering the main components and causing blockages. Furthermore, unqualified rubber after screening is discharged through the discharge pipe for easy recycling or secondary processing, reducing waste.

[0017] 2. When the spiral blades rotate, they also drive the drive pulley to rotate. The drive pulley, through the first belt and the driven pulley, drives the blade to rotate. The rotation of the blade is controlled by the power of the spiral blades. The blade can prevent the rubber after screening from accumulating or bridging in the feed hopper, ensuring that the material enters the cylinder evenly and avoiding blockage.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 Figure 1 - Figure 4 This utility model provides a technical solution: a screw conveyor for processing recycled rubber, including a screw conveyor 1 for conveying rubber, the screw conveyor 1 including:

[0025] The main component 11 includes a spiral blade 112 rotatably mounted inside the cylinder 111. A first motor 113 is installed at the left end of the cylinder 111 and is used to drive the spiral blade 112. A feed hopper 114 is fixed on the upper left side of the cylinder 111, and a discharge port 119 is fixed on the lower right side of the cylinder 111.

[0026] The screening assembly 12 includes a bin body 121 fixed to the upper end of the feed hopper 114. Inside the bin body 121, a fine screening cylinder 122, a medium screening cylinder 123, and a coarse screening cylinder 124 are rotatably installed from left to right. The fine screening cylinder 122 is located directly above the feed hopper 114. Two discharge pipes 126 are fixed at the bottom of the bin body 121, and the two discharge pipes 126 are located directly below the medium screening cylinder 123 and the coarse screening cylinder 124, respectively. A driving component 127 is provided on the bin body 121 to drive the fine screening cylinder 122, the medium screening cylinder 123, and the coarse screening cylinder 124 to rotate.

[0027] In this embodiment, rubber is poured from the ramp 125 into the silo 121 and falls onto the fine screening cylinder 122. Rubber smaller than the screen openings of the fine screening cylinder 122 falls directly into the feed hopper 114, while rubber larger than the screen openings of the fine screening cylinder 122 is conveyed to the medium screening cylinder 123. Rubber smaller than the screen openings of the medium screening cylinder 123 is discharged through the discharge pipe 126 on the left side, while rubber larger than the screen openings of the medium screening cylinder 123 is conveyed to the coarse screening cylinder 124 and discharged through the screen openings of the coarse screening cylinder 124 through the discharge pipe 126 on the right side. By setting up three-stage screening cylinders to classify and screen rubber particles, large pieces of rubber are prevented from entering the main component 11 and causing blockages. Furthermore, unqualified rubber after screening is discharged through the discharge pipe 126, facilitating recycling or secondary processing and reducing waste.

[0028] Specifically, the screening assembly 12 also includes a ramp 125 located at the left end of the bin body 121, and the lower end of the ramp 125 is on the same horizontal line as the axis of the fine screening cylinder 122.

[0029] In this embodiment, the ramp 125 allows the poured rubber material to slide smoothly into the fine screening cylinder 122, ensuring a smooth screening process, preventing material from accumulating at the inlet of the silo, and improving screening efficiency.

[0030] Specifically, the drive component 127 includes a second motor 1271 fixed at the rear end of the fixed chamber 121 and used to drive the fine screening cylinder 122 to rotate. The front ends of the fine screening cylinder 122, the medium screening cylinder 123 and the coarse screening cylinder 124 are all fixed with transmission pulleys 1272, and a second belt 1273 is installed between adjacent transmission pulleys 1272.

[0031] In this embodiment, the fine screening cylinder 122 is driven to rotate by the second motor 1271, and the fine screening cylinder 122 drives the medium screening cylinder 123 and the coarse screening cylinder 124 to rotate synchronously through the transmission pulley 1272 and the second belt 1273.

[0032] Specifically, the main component 11 also includes a blade 115 that is rotatably installed inside the feed hopper 114.

[0033] In this embodiment, the blade 115 can prevent the screened rubber from accumulating or bridging in the feed hopper 114, ensuring that the material enters the cylinder 111 evenly and avoiding blockage.

[0034] Specifically, the main component 11 also includes a driven pulley 116 fixed to the left end of the blade 115, a driving pulley 117 fixed to the left end of the spiral blade 112, and a first belt 118 installed between the driving pulley 117 and the driven pulley 116.

[0035] In this embodiment, when the spiral blade 112 rotates, it also drives the drive pulley 117 to rotate. The drive pulley 117 drives the blade 115 to rotate through the first belt 118 and the driven pulley 116.

[0036] Specifically, the main component 11 also includes a cylinder cover 1110 hinged to the upper end of the cylinder 111, and the front end of the cylinder cover 1110 is fixed to the front end of the cylinder 111 by bolts.

[0037] In this embodiment, the cylinder cover 1110 can be opened from the cylinder body 111, making it easy to clean the spiral blades 112 in the cylinder body 111 when they become blocked.

[0038] The working principle and usage process of this utility model are as follows: First, the rubber is poured into the hopper 121 from the ramp 125. The ramp 125 allows the poured rubber material to slide smoothly into the fine screening cylinder 122. At the same time, the second motor 1271 drives the fine screening cylinder 122 to rotate. The fine screening cylinder 122 drives the middle screening cylinder 123 and the coarse screening cylinder 124 to rotate synchronously through the transmission pulley 1272 and the second belt 1273. Rubber smaller than the screen holes of the fine screening cylinder 122 falls directly into the feed hopper 114. Rubber larger than the screen holes of the fine screening cylinder 122 is transported to the middle screening cylinder 123. Rubber smaller than the screen holes of the middle screening cylinder 123 is discharged through the discharge pipe 126 on the left side. Rubber larger than the screen holes of the middle screening cylinder 123 is transported to the coarse screening cylinder 124 and discharged through the screen holes of the coarse screening cylinder 124 through the discharge pipe 126 on the right side.

[0039] Then, the first motor 113 drives the spiral blades 112 to drive the drive pulley 117 to rotate. The drive pulley 117 drives the blade 115 to rotate through the first belt 118 and the driven pulley 116. The blade 115 can prevent the screened rubber from accumulating or bridging in the feed hopper 114, ensuring that the material enters the cylinder 111 evenly and avoiding blockage. Finally, the spiral blades 112 transport the rubber and discharge it from the outlet 119.
