Description

Technical Field

[0001] The utility model belongs to the technical field of production devices for recycled rubber powder, and particularly relates to a device for cooling high-temperature and low-viscosity desulfurized rubber powder. Background Art

[0002] After years of development in the recycled rubber industry, a desulfurization and regeneration process mainly based on "high-temperature and high-pressure dynamic desulfurization" has been formed. Its desulfurization reaction is completed in a desulfurization tank. A regenerant and water are added into the desulfurization tank together. The working pressure is about 2.2 MPa, the working temperature is about 220 °C, and after about 3 hours of desulfurization time, the pressure is released and cooled, and then the desulfurized rubber powder is taken out. Then, it is pressed into sheets by 3 to 4 high-speed refining machines to obtain recycled rubber.

[0003] In recent years, the production of recycled rubber by the atmospheric pressure continuous desulfurization method has been gradually promoted. Generally, waste rubber powder and a regenerant are premixed, and then continuously conveyed into a desulfurization machine. In the sealed conveying state inside a spiral or screw device, desulfurization and cooling are completed through heating desulfurization and jacketed spiral cooling. Subsequently, if a screw refining machine is used, the whole process can be made airtight, continuous, and automated. However, currently, the temperature difference between the contact surface of the device for cooling rubber powder at the entrance of the cooling equipment and the rotating spiral ribbon is relatively large, which easily adheres to the spiral ribbon and causes blockage. Moreover, peculiar smells and waste gases are generated during the cooling process. If directly discharged without treatment, it will cause environmental pollution. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for cooling high-temperature and low-viscosity desulfurized rubber powder in order to solve the problems that the rubber powder in the existing cooling device easily adheres to the spiral ribbon and causes blockage, and peculiar smells and waste gases are generated during the cooling process.

[0005] The utility model realizes the above purpose through the following technical solutions: It includes a cooling box. Support legs are provided on both sides of the cooling box. An exhaust port is provided through the upper part of the cooling box. A feeding port is provided through the side of the exhaust port at the upper part of the cooling box.

A connection box is provided on the side of the motor. A first connection disk is provided inside the connection box. A second connection disk is provided on the side of the first connection disk.

A hollow shaft is provided on the side of the connecting water pipe. A first connection groove is provided on the side of the hollow shaft. A second connection groove is provided at the end of the cooling box close to the connection box.

[0006] Further, the stirring device includes a first rotating shaft, a second rotating shaft is provided at one end of the first rotating shaft close to the connection box, a number of first connecting columns are penetrated through above the first rotating shaft, a number of second connecting columns are penetrated through below the first rotating shaft, and a number of third connecting columns are penetrated through both sides of the first rotating shaft. A stirring spiral ribbon is provided around the side of the first connecting column, and a conveying spiral ribbon is provided around the side of the first connecting column away from the stirring spiral ribbon.

[0007] Further, the second rotating shaft is fixedly connected to the first connecting disk. The second rotating shaft is located inside the second connecting groove and the two are in mutual fit and movably connected. The first rotating shaft is located inside the first connecting groove and the two are in mutual fit and movably connected. The connecting water pipe is penetrated and connected to the first rotating shaft.

[0008] Further, the interiors of the first rotating shaft, the first connecting column, the second connecting column and the third connecting column are all hollow, and the first connecting column, the second connecting column, the third connecting column and the first rotating shaft are all penetrated and connected.

[0009] Further, both the stirring spiral ribbon and the conveying spiral ribbon are fixedly connected to the first connecting column, the second connecting column and the third connecting column.

[0010] Further, the connecting water pipe is located inside the processing groove.

[0011] Beneficial effects: The design of the present utility model is reasonable and has the following beneficial effects:

[0012] 1. When the present utility model is in use, the added rubber powder is stirred by the stirring spiral ribbon and the conveying spiral ribbon outside the first rotating shaft. At the same time, cold water from the outside is connected through the connecting water pipe, so that the cold water enters the first rotating shaft and the three connecting columns. In this way, the rubber powder can be cooled as soon as possible during the stirring process. At the same time, water is added through the water inlet, and multi-stage water spraying is carried out to form high-temperature water vapor to further isolate the air. Moreover, a large amount of waste gas, such as SO, can be adsorbed during the evaporation process of water, reducing the peculiar smell generated by the rubber powder. At the same time, the rubber powder is cooled from the outside to the inside, making the desulfurization of the rubber powder more uniform;

[0013] 2. During the stirring process, calcium powder can be added through the feeding port. The addition of calcium powder reduces the adhesion between the desulfurized rubber powders to a certain extent and reduces the risk of equipment blockage. After the cooling is completed, the gas generated during the cooling process will be discharged and collected through the exhaust port for centralized treatment, which can prevent the waste gas from being directly discharged and polluting the environment.
