Technical Field

[0001] The utility model relates to the technical field of recycled rubber production, in particular to a recycled rubber production cooling device. Background Art

[0002] Recycled rubber is a kind of rubber that has a certain plasticity and can be reused, which is transformed from waste vulcanized rubber products through physical and chemical processes such as crushing, heating, mechanical treatment and chemical treatment. During the recycling process of recycled rubber, the rubber powder needs to be cooled.

[0003] At present, recycled rubber powder is usually cooled by air cooling, but the flowing cold wind can easily cause the rubber powder to be lifted and dispersed into the air, causing air pollution and also causing the loss of rubber powder raw materials. Therefore, we propose a recycled rubber production cooling device. Utility Model Content

[0004] The utility model aims to provide a cooling device for recycled rubber production, which has the advantages of being able to cool recycled rubber powder while preventing the rubber powder from being lifted up, thereby reducing the loss of rubber powder and avoiding air pollution. It solves the problem that the recycled rubber powder is usually cooled by air cooling, but the flowing cold wind easily causes the rubber powder to be lifted up and dispersed into the air, causing air pollution, and also causing the loss of rubber powder raw materials.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a regenerated rubber production cooling device, comprising a regenerated rubber powder cooling box and a rubber powder conveyor belt, the regenerated rubber powder cooling box is provided with a rubber powder conveyor belt, a feed hopper is fixedly installed on one side of the upper surface of the regenerated rubber powder cooling box, a discharge outlet is provided on the side of the outer surface of the regenerated rubber powder cooling box away from the feed hopper, branch pipes are symmetrically fixedly installed at both sides above the rubber powder conveyor belt inside the regenerated rubber powder cooling box, cooling water input pipes and cooling water discharge pipes are fixedly connected to the upper surfaces of the two branch pipes, and a plurality of hollow heat exchange plates are fixedly installed at equal distances on the lower surfaces of the branch pipes.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model achieves the effect of cooling the recycled rubber powder while avoiding the rubber powder from being lifted up, thereby reducing the loss of rubber powder and avoiding air pollution by arranging a recycled rubber powder cooling box, a rubber powder conveyor belt, a branch pipe, a hollow heat exchange plate, a branch pipe, a cooling water input pipe and a cooling water discharge pipe. The recycled rubber powder falls from the feed hopper onto the rubber powder conveyor belt, the rubber powder conveyor belt drives the rubber powder to move, and the cooling water enters the hollow heat exchange plate from the cooling water input pipe. The rubber powder on the rubber powder conveyor belt contacts the hollow heat exchange plate and exchanges heat, thereby cooling the rubber powder, and the heat is taken away by the cooling water. The heated cooling water is discharged from the cooling water discharge pipe. In this process, the rubber powder will not be lifted up and dispersed into the air to cause pollution, thereby reducing the loss of rubber powder.

[0013] 2. The utility model provides a toothed rake to move and turn over the recycled rubber powder on the rubber powder conveyor belt, which is beneficial to the full contact between the rubber powder and the hollow heat exchange plate and improves the cooling efficiency of the rubber powder.

[0014] 3. The utility model achieves the effect of scraping off the regenerated rubber powder remaining on the rubber powder conveyor belt by arranging a hydraulic rod, a fixed frame, a lifting plate and a rubber scraper. The hydraulic rod makes the rubber scraper on the lifting plate contact with the rubber powder conveyor belt. When the rubber powder conveyor belt rotates, the rubber scraper scrapes off the regenerated rubber powder remaining on the rubber powder conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Branch pipes 11 are symmetrically fixedly installed inside the recycled rubber powder cooling box 1 at both sides above the rubber powder conveyor belt 7. The upper surfaces of the two branch pipes 11 are fixedly connected with a cooling water input pipe 5 and a cooling water discharge pipe 4 respectively. A plurality of hollow heat exchange plates 10 are equidistantly fixedly installed on the lower surface of the branch pipes 11. The two ends of each hollow heat exchange plate 10 are respectively connected to the two branch pipes 11. The cooling water enters the hollow heat exchange plate 10 through the cooling water input pipe 5 and is then discharged from the cooling water discharge pipe 4. A plurality of tooth rakes 9 are equidistantly fixedly installed on the top of the inner wall of the recycled rubber powder cooling box 1. The tooth rakes 9 play a role of stirring and turning over the recycled rubber powder on the rubber powder conveyor belt 7, which is beneficial to the full contact between the rubber powder and the hollow heat exchange plate 10 and improves the cooling efficiency of the rubber powder.

[0024] When the utility model is in use, the recycled rubber powder falls from the feed hopper 3 onto the rubber powder conveyor belt 7, the rubber powder conveyor belt 7 drives the rubber powder to move, and the cooling water enters the hollow heat exchange plate 10 from the cooling water input pipe 5. The rubber powder on the rubber powder conveyor belt 7 contacts the hollow heat exchange plate 10 and exchanges heat, so that the rubber powder is cooled, and the heat is taken away by the cooling water. The heated cooling water is discharged from the cooling water discharge pipe 4. In this process, the rubber powder will not be lifted up and dispersed into the air to cause pollution, and the loss of the rubber powder is also reduced.

[0027] In this embodiment, the hydraulic rod 16 makes the rubber scraper 13 on the lifting plate 14 contact with the rubber powder conveyor belt 7. When the rubber powder conveyor belt 7 rotates, the rubber scraper 13 scrapes off the regenerated rubber powder remaining on the rubber powder conveyor belt 7.
