Description

Technical Field

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

[0002] The rubber production process typically uses rubber mixing equipment to refine the raw rubber. This equipment transforms the raw rubber into a plastic state, followed by rolling, filtering, sheeting, cutting, and storage. Because the production process involves continuous heating, the rubber must first be cooled after desulfurization and extrusion before proceeding to the next step.

[0003] Existing technologies mostly use air cooling or water cooling. Air cooling has low efficiency and requires a long working stroke. Sulfur-containing waste gas is also generated during the air cooling operation. Rubber is easily exposed to the air environment during the air cooling process, which makes the surface easily oxidized, affecting the quality of the finished product. Water cooling requires continuous supply of cooling water, and water vapor is easily attached to the rubber surface after water cooling. Additional drying operations are also required, and the water cooling process has high energy consumption. Utility Model Content

Thereafter, the rubber passes through a first air-cooling part and a second air-cooling part in sequence. The water vapor on both sides is dried and the rubber is cooled as a whole in the first air-cooling part and the second air-cooling part.

A group of pressure rollers are provided at the top of the first air-cooled conveyor belt and the end of the second air-cooled conveyor belt away from the discharge port. The pressure rollers are arranged along the width direction of the cooling box and the two ends are positioned and rotatably installed in the cooling box. A plurality of fans are arranged on the top of the cooling box, and the fans are arranged in an array along the length direction of the cooling box.

[0017] By adopting the above technical solution, the fan cooperates with the second air-cooling conveyor belt to cool and dry the other side of the rubber, thereby controlling the overall discharge temperature of the rubber to be appropriate.

[0018] Furthermore, an inclined water guide plate is provided under the first air-cooled conveyor belt, and the water guide plate is arranged parallel to the first air-cooled conveyor belt and fixed in the cooling box. A water diversion plate is provided under the second air-cooled conveyor belt, and the water diversion plate is arranged along the length direction of the cooling box and fixed in the cooling box on both sides.

The guide frame 121 cooperates with the guide roller 14 to guide the rubber outflow, and the arc-shaped guide plate 1212 cooperates with the rubber outflow arc and provides support for the rubber. In order to enhance the supporting force of the guide plate 1212, a torsion spring can be set on the rotating shaft of the guide plate 1212. The two ends of the torsion spring respectively abut against the bottom of the guide frame 121 and the bottom of the guide plate 1212 to ensure that the guide plate 1212 is always lifted.

The fans 72 cooperate with the second air-cooling conveyor belt 71 to cool and dry the other side of the rubber, thereby maintaining the overall discharge temperature of the rubber at an appropriate level.

[0043] An inclined water deflector 612 is installed below the first air-cooling conveyor belt 61. This deflector 612 is arranged parallel to the first air-cooling conveyor belt 61 and is fixed within the cooling box 1. A water guide plate 712 is installed below the second air-cooling conveyor belt 71. This deflector plate 712 runs along the length of the cooling box 1, with its front and rear sides fixed within the cooling box 1. The front and rear sides of the deflector plate 712 are also tilted downward, and water diversion grooves 7121 are defined at the bottom of each side.

The gas collection box 9 is connected to the cooling box 1 through a gas collecting pipe 91, and the gas collecting pipe 91 is connected to the front side of the cooling box 1 near the top. The nitrogen storage pipe inputs nitrogen into the cooling box 1 to isolate oxygen. In order to ensure the stability of the air pressure in the cooling box 1, a gas collection box 9 is provided to collect the displaced gas. At the same time, the gas collection box 9 also collects sulfur-containing waste gas during the cooling process. The gas collection box 9 can subsequently perform waste gas treatment and nitrogen separation to facilitate the recycling of nitrogen.

[0045] A heat exchanger 10 is also installed outside the cooling box 1. A circulating water pipe 15 is also installed near the bottom of the cooling box 1.
