Description

Technical Field

[0001] The utility model relates to the technical field of rubber production, and particularly relates to an exhaust gas treatment device for rubber production. Background Art

[0002] The main raw materials of rubber products are raw rubber, various compounding agents, as well as fiber and metal materials as skeleton materials. The basic production process of rubber products includes six basic processes: plasticating, mixing, calendering, extruding, molding, and vulcanizing. The processing process of rubber mainly solves the contradiction between plasticity and elasticity. Through various processing means, elastic rubber is turned into plasticated rubber with plasticity, and then various compounding agents are added to make semi-finished products, and then the semi-finished products with plasticity are vulcanized into rubber products with high elasticity and good physical and mechanical properties. Waste gas will be generated during the rubber processing process. If the waste gas is directly discharged without treatment, it will affect the environment.

[0003] After retrieval, the utility model patent with the publication number of CN213853597U discloses an exhaust gas treatment device for recycled rubber production, which includes a filtering mechanism for filtering exhaust gas, an air extraction mechanism for extracting exhaust gas, and also includes a storage mechanism for storing chemical agents for treating exhaust gas. The filtering mechanism is arranged at the upper end of the storage mechanism, one end of the filtering mechanism is provided with the air extraction mechanism, the air extraction mechanism is connected with the storage mechanism by screws, and the filtering mechanism is welded to the storage mechanism; this patent can filter out particulate matters in the exhaust gas by setting a filter screen and an ash storage hopper, and can store chemical agents for treating exhaust gas by chemical means by setting a water storage tank. However, the above patent still has the following deficiencies: Although the particulate matters in the exhaust gas can be filtered through the filter screen,

[0004] the particulate matters are easily attached to the filter screen and not easy to fall off. At the same time, the particulate matters on the filter screen affect the flow of the exhaust gas in the outer shell, and the practicability is poor; moreover, although the medicament atomized by the atomizer can enter the first air extraction pipe and contact with the exhaust gas, when the flow rate of the exhaust gas in the first air extraction pipe is too fast, it is not easy to ensure that the atomized medicament can be in full contact with the exhaust gas, which affects the quality of exhaust gas treatment. For this reason, we propose an exhaust gas treatment device for rubber production. Summary of the Utility Model
