UTILITY MODEL CONTENTS

[0003] The utility model aims at providing a sewage treatment equipment for metal processing to solve the problems in the prior art.

[0004] The above technical purpose of the utility model is realized by the following technical scheme:

[0005] A sewage treatment equipment for metal processing, comprising a sedimentation tank, a treatment tank, a filter tank and a discharge tank, the sedimentation tank, the treatment tank, the filter tank and the discharge tank are sequentially communicated through pipelines, and automatic valves are arranged on the pipelines that are communicated two by two; a partition is arranged in the sedimentation tank, the partition is used for dividing the inside of the sedimentation tank into two spaces with different sizes, a through hole is arranged at the bottom of the partition, a stirring device is arranged in the treatment tank, a filter grid is arranged at the top of the filter tank, and a liquid level meter is arranged in the discharge tank.

[0006] Through the above technical scheme, when the sewage enters the sedimentation tank, it is buffered and then slowly enters the other side of the sedimentation tank through the through hole at the bottom of the partition due to the blockage of the partition. When the liquid level completely covers the through hole, the flow of the sewage is slower, so that the one side of the inside of the sedimentation tank has the function of sedimentation. The sedimented sewage enters the treatment tank, and the heavy metal ions in the sewage are removed, so that the sewage is treated. Since the equipment is mainly used for metal powder processing, the solid metal powder can be mostly precipitated in the sedimentation tank, so the efficiency of the sewage treatment tank is improved. The filter tank is used for filtering the solidified metal salt particles in the treatment tank, and then the liquid level reaches a certain height after the liquid in the discharge tank is precipitated for a period of time, and the liquid is uniformly discharged.

[0007] In further embodiments, the stirring device comprises a waterproof motor fixedly installed on the inner bottom of the treatment tank and stirring blades in transmission connection with the output shaft of the waterproof motor.

[0008] By adopting the above technical scheme, the stirring can accelerate the diffusion and reaction speed of the medicament inside the treatment tank.

[0009] In further embodiments, the bottom of the filter grid is provided with a fixing frame, and the top of the filter grid is paved with a sponge layer.

[0010] In further embodiments, the inside of the sedimentation tank is provided with a baffle for dividing the inside of the sedimentation tank into three spaces in cooperation with the partition plate, and one side of the baffle is provided with an inclined surface.

[0011] In further embodiments, the inner wall of the treatment tank is provided with a corrosion-resistant coating.

[0012] By adopting the above technical scheme, because the chemical reagent is injected into the treatment tank for a long time, in order to increase the corrosion resistance of the inner wall of the treatment tank, a corrosion-resistant coating needs to be sprayed on the inner wall of the treatment tank.

[0013] In further embodiments, the inside top end of the sedimentation tank is provided with a plurality of sterilization lamps.

[0014] In summary, the present application has the following beneficial effects:

[0015] 1. When the sewage enters the sedimentation tank, it is blocked by the partition plate and slowly enters the other side of the inside of the sedimentation tank through the through hole at the bottom of the partition plate after being buffered. When the liquid level completely passes through the through hole, the flow of the sewage will be slower, so that the inside of the sedimentation tank has a sedimentation function. The sedimentation of the sewage removes the heavy metal ions in the sewage, realizes the treatment of the sewage, and because the present device is mainly used for metal powder processing, the solid metal powder can be mostly precipitated in the sedimentation tank, so the efficiency of the sewage treatment tank is improved. The filter tank is used for filtering the solidified metal salt particles in the treatment tank, and then after being precipitated in the discharge tank for a period of time, the liquid level reaches a certain height and is uniformly sampled and discharged.
