Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to municipal sewage treatment equipment. Background Art

[0002] Municipal sewage refers to sewage generated in cities or towns. This sewage mainly comes from wastewater generated by activities such as residents, industry, commerce and public facilities. Municipal sewage contains various organic matter, inorganic matter, microorganisms and other pollutants, such as dissolved oxygen, suspended matter, heavy metals, organic compounds and nutrients. If sewage is discharged directly into natural water bodies, it will cause eutrophication of water bodies, water pollution, destruction of water ecosystems and pollution of water sources. In addition, microorganisms and harmful substances in municipal sewage may also spread diseases, so municipal sewage treatment equipment is needed to treat municipal sewage.

[0003] Sewage treatment equipment generally first treats sewage through a filter in order to remove particulate impurities in the sewage. However, after long-term use, the particulate impurities in the sewage are likely to clog the filter holes of the filter, affecting the filter's continuous filtration of the sewage. In addition, during the sewage sedimentation process, it is easy to ferment and produce foul-smelling gases, which are emitted into the air during filtration, causing pollution to the environment. Utility Model Content

[0004] The main purpose of the utility model is to provide a municipal sewage treatment equipment to solve the above problems.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A municipal sewage treatment device comprises a sedimentation tank and a filter box arranged on the side of the sedimentation tank, a deodorizing component connected to the sedimentation tank, and a filter component connected to the filter box;

[0007] The deodorizing assembly includes an air pump fixedly connected to the top of the sedimentation tank, and an activated carbon adsorption box arranged on the side of the air pump for deodorizing the gas inside the sedimentation tank;

[0008] The filter assembly comprises a delivery pump fixedly connected to the outer wall of the sedimentation tank, a discharge pipe fixedly connected to the water outlet of the delivery pump, and a filter screen cylinder movably arranged inside the filter box for filtering water discharged from the sedimentation tank.

[0009] Preferably, the deodorizing assembly further comprises a drying box fixedly connected to the top of the sedimentation box, the drying box is arranged between the vacuum pump and the activated carbon adsorption box, and the drying box and the activated carbon adsorption box are connected through a pipeline.

[0010] Preferably, the deodorizing assembly further comprises a plurality of partitions fixedly connected to the interior of the drying box and arranged in a staggered manner, and a solid desiccant placed on top of the partitions.

[0011] Preferably, the filter assembly further comprises a servo motor fixedly connected to the outer side wall of the filter box, and a mounting plate fixedly connected to the outer side wall of the output end of the servo motor.

[0012] Preferably, the filter assembly further comprises a protective sleeve and an electric telescopic rod fixedly connected to the outer side wall of the mounting plate, a connecting rod fixedly connected to the output end of the electric telescopic rod, and a transmission plate fixedly connected to the end face of the connecting rod.

[0013] Preferably, the filter assembly further comprises a positioning rod fixedly connected to the outer surface of the transmission disc, a positioning hole provided at the bottom of the filter screen cylinder, and a fixing bolt threadedly connected to the positioning rod.

[0014] Preferably, the filter assembly further comprises a threaded cover threadedly connected to the filter screen cylinder, and a through hole opened on the outer surface of the threaded cover, wherein the inner diameter of the through hole is equal to the outer diameter of the discharge pipe.

[0015] The utility model has the following beneficial effects:

[0016] 1. By starting the vacuum pump, the gas inside the sedimentation box is extracted and transported to the inside of the drying box. At this time, the solid desiccant inside the drying box will absorb the moisture in the gas.

At this time, the sewage will first be filtered through the filter cylinder and finally stored in the filter box. During this process, the servo motor is in working state to drive the filter cylinder to rotate to increase the contact area between the filter cylinder and the sewage, reduce the occurrence of filter cylinder blockage, and improve the filtering effect of the device. It can also control the extension and retraction of the electric telescopic rod to further increase the contact area between the filter cylinder and the sewage. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] First, the sewage is transported to the sedimentation tank 1 for static sedimentation, and the vacuum pump 301 is started to extract the gas inside the sedimentation tank 1 and transport it to the inside of the drying box 302. At this time, the solid desiccant 305 inside the drying box 302 will adsorb the moisture in the gas. In this process, the circulation time of the gas inside the sedimentation tank 1 in the drying box 302 is extended by means of multiple staggered partitions 304, thereby improving the drying effect of the gas and preventing the moisture carried in the gas from interfering with the adsorption effect of the activated carbon. Finally, the gas is transported to the inside of the activated carbon adsorption box 303 under the action of the vacuum pump 301 to remove the odor in the gas.

[0032] The deodorizing assembly includes an air pump 301 fixedly connected to the top of the sedimentation tank 1, and an activated carbon adsorption box 303 arranged on the side of the air pump 301 for deodorizing the gas inside the sedimentation tank 1;

[0033] The filtration assembly includes a delivery pump 401 fixedly connected to the outer wall of the sedimentation tank 1, a discharge pipe 402 fixedly connected to the water outlet of the delivery pump 401, and a filter screen 403 movably arranged inside the filter box 2 for filtering the water discharged from the sedimentation tank 1, wherein the discharge pipe 402 extends from one end of the delivery pump 401 to the interior of the filter box 2.

[0034] The filter assembly further includes a servo motor 404 fixedly connected to the outer wall of the filter box 2 , and a mounting plate 405 fixedly connected to the outer wall of the output end of the servo motor 404 , wherein the mounting plate 405 is located inside the filter box 2 .
