Embodiment Construction
[0013] Such as figure 1 As shown, a tank bottom drainage pipe connection device provided by a preferred embodiment of the present invention includes a reaction tank, a drain outlet 2 and a drain pipe 3 arranged on the bottom plate 1 of the reaction tank. The drain pipe 3 is sealed butted with the drain port 2 on the bottom plate of the reaction tank through an acid and alkali resistant tank bottom pipe connection box 4 . A ring-shaped edge 6 is provided at the port where the pipe connection box 4 at the bottom of the tank is connected to the drain outlet 2 of the bottom plate of the reaction tank, and a filter box 5 is also provided in the port. In this embodiment, the annular edge 6 of the port of the pipe connection box 4 at the bottom of the tank adopts a double-sided welding structure 7 to seal butt joint with the drain outlet 2 of the bottom plate of the reaction tank. The lower end of the pipe connection box 4 at the bottom of the groove is connected with the drain pipe...

The invention discloses a connecting device for a tank-bottom drainage pipeline, which comprises a reaction tank, a water drainage port and a drainage pipe, wherein the water drainage port is arranged on the bottom plate of the reaction tank; and the drainage pipe is in sealing butt joint with the water drainage port on the bottom plate of the reaction tank by an acid-proof and alkali-proof tank-bottom pipeline connecting box. The acid-proof and alkali-proof tank-bottom pipeline connecting box is arranged between the tank body and the drainage pipe, and a filter box is arranged in the end port of the tank-bottom pipeline connecting box connected with the water drainage port, thereby increasing the welding area, and effectively preventing the joint from liquid leakage. The end port of the bottom plate of the reaction tank can be provided with a filter box to perform a filtering function and effectively prevent pipelines from being blocked, thereby effectively overcoming the technical defect that the environment and the safe production are affected because the connection of the drainage pipes on the bottom of the reaction tank can be easily corroded.
Description
technical field [0001] The invention relates to silicon material processing equipment, in particular to a connection device for a drainage pipe at the bottom of a reaction tank in cleaning equipment and wet processing equipment. Background technique [0002] In solar cleaning equipment and wet processing equipment, especially in chain solar cleaning equipment and wet processing equipment, the pipeline is usually directly connected to the bottom of the reaction tank to drain the waste liquid in the tank. Affected by the wall thickness of the tank, the connection between the pipe and the tank is not tightly sealed. Due to the small sealing area, in a strong acid and alkali environment, even acid and alkali resistant materials will be slightly corroded with long-term use. At this time, there will be poor sealing at the connection between the pipeline and the tank body, which will directly lead to liquid leakage from the tank body, causing environmental pollution and affecting ...
