Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment devices, and in particular relates to an environmentally friendly sewage treatment device. Background Art

[0002] Sewage includes industrial sewage and domestic sewage. Industrial sewage includes production sewage and production sewage, which refers to sewage and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Sewage treatment equipment for environmental governance is a kind of equipment used to treat sewage before discharging it. The equipment consists of a disinfection part, a sedimentation part and an anaerobic part. The sewage is discharged after a series of sedimentation and disinfection treatment, which will not cause damage to the environment and play a role in environmental governance.

[0003] When the existing sewage treatment equipment for environmental governance is used, the sewage is transported into the treatment box through the water inlet, and the treatment liquid is added through the medicine box set on the top. Then, under the action of the liquid, the sewage is treated through the sedimentation part, the anaerobic part and the disinfection part in the box, and then discharged through the drain port, which effectively avoids damage to the environment. However, there are the following defects:

[0004] (1) When adding chlorine-containing disinfectant solution to the environmental sewage treatment device, the metering pump is used to achieve timed and quantitative addition. However, in actual sewage treatment, the sewage is not always in a state of being discharged. Therefore, if no sewage is discharged for a certain period of time, while the metering pump continues to work to add liquid, it is easy to cause excessive internal liquid and excessive residual chlorine, resulting in secondary pollution of sewage. For this reason, we propose a sewage treatment device for environmental protection. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The flap, end, cable, spring and metering block are designed to be rotatably installed in the water inlet. When sewage is discharged into the treatment box through the water inlet, the sewage impacts the flap to flip up. At this time, the flap pulls the metering block through the cable, so that the metering block stops blocking the metering hole, and then the chlorine-containing liquid is discharged into the treatment box. When the water injection stops, the flap flips down and stops pulling the metering block. At this time, the spring in the compressed state releases the elastic force, pushing the metering block to slide into the metering hole to block, and the liquid stops injecting. The liquid is added when water is discharged, and the addition is stopped in time when no water is injected, effectively avoiding secondary pollution of the treated water caused by excessive addition of medicine. The designed guide wheel group is used to realize the lubrication of the cable traction reversing guide to avoid the cable being worn and affecting the service life. The designed correction rod and sliding hole are used to support and correct the spring to avoid excessive extrusion and bending and loss of elasticity. The designed rubber pad is placed at the end of the quantitative block to achieve sealing of the fitting position of the quantitative block end and the quantitative hole.

The flip cover 11 is rotatably installed in the water inlet 2 through the designed flip cover 11, the end 6, the cable 10, the spring 19 and the metering block 16. When When sewage is discharged into the treatment box 1 through the water inlet 2, the sewage impacts the flap 11 to flip up. At this time, the flap 11 pulls the quantitative block 16 through the cable 10, so that the quantitative block 16 stops blocking the quantitative hole 18, and then the chlorine-containing liquid is discharged into the treatment box 1. When it stops injecting water, the flap 11 flips down and stops pulling the quantitative block 16. At this time, the spring 19 in a compressed state releases its elastic force, pushing the quantitative block 16 to slide into the quantitative hole 18 for blocking, and the liquid stops injecting, so that the liquid is discharged with water, that is, the dosing is done, and the dosing is stopped in time when there is no water injected, effectively avoiding excessive dosing and causing secondary pollution to the treated water. Two guide wheel groups 9 are provided on the cable 10, and each guide wheel group 9 is respectively fixed on the corresponding water inlet 2 and the surface of the end 6.
