Description

Technical Field

[0001] The utility model relates to the technical field of sewage discharge devices, in particular to an anti-blocking sewage discharge device. Background Art

[0002] In daily urban sewage treatment channels, different channel environments cause different problems due to blockage, and different methods of preventing blockage need to be formulated according to the local environment. Urban sewage treatment refers to measures taken to change the nature of sewage so that it does not harm the environmental waters. Most of the water used in human production and life is discharged into sewage pipes;

[0003] In order to prevent the blockage of the sewage pipe, a filtering mechanism is usually set at the sewage discharge port to filter the debris in the sewage when the sewage is discharged, so as to prevent the debris from entering the sewage pipe and prevent the sewage pipe from being blocked. However, in actual use, the existing filtering mechanism has a simple structure, only has a filtering effect, and has a single function. As a result, the filtering mechanism needs to be manually checked and cleaned regularly, which is time-consuming and laborious. In addition, people have limited energy and are prone to forget to clean it, causing blockage, which increases the difficulty of sewage discharge of the sewage discharge device. For this reason, we propose an anti-blocking sewage discharge device. Utility Model Content

[0004] The main purpose of the utility model is to provide an anti-clogging sewage discharge device, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blockage-proof sewage discharge device, comprising a filter cartridge, a water inlet pipe and an inspection cover, wherein a filter assembly is detachably provided at the upper end of the inner cavity of the filter cartridge, a flow meter is provided in the inner cavity at one end of the water inlet pipe, a servo motor is embedded and connected to the top of the inspection cover, and the power output end of the servo motor passes through the inspection cover and extends to the inside of the filter cartridge, a transmission rod is fixedly connected to the power output end of the servo motor, and the transmission rod body extends to the inside of the filter assembly, scrapers are fixedly connected to both sides of the upper end of the transmission rod, and crushing knives are detachably connected to both sides of the lower end of the transmission rod.

[0006] Preferably, the filter assembly comprises a connecting plate, and a filter basket is detachably connected to the bottom end of the connecting plate.

[0007] Preferably, a fixed edge is fixedly connected to the upper end of the inner cavity of the filter cartridge.

[0008] Preferably, a water inlet for water intake into the filter cartridge is provided at an upper end of one side of the filter cartridge, and one end of the water inlet pipe is detachably connected to the inner cavity of the water inlet.

[0009] Preferably, a drainage outlet is provided at a lower end of the filter cartridge on one side relative to the water inlet, and a sewage pipe is detachably connected to the outer side of the drainage outlet.

[0010] Preferably, the surface of the crushing knife is coated with a corrosion-resistant layer.

[0011] Preferably, a stirring rod is fixedly connected to the bottom end of the transmission rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model uses a filter cartridge to discharge sewage. The filter cartridge is directly installed at the water inlet of the sewage pipe. The sewage directly enters the filter cartridge through the water inlet pipe, and the filter basket arranged inside the filter cartridge is used to filter larger debris in the sewage, thereby preventing the larger debris from entering the sewage pipe and avoiding clogging of the sewage pipe. At the same time, when there are too many debris in the filter cartridge, the servo motor can drive the transmission rod and the scrapers and crushing knives arranged on both sides of the transmission rod to rotate. The rotating scraper can clean the debris adhered to the inner wall of the filter basket, thereby avoiding clogging of the filter basket, and the crushing knife can crush the larger debris into small pieces and then discharge them with the sewage. Then, they are quickly discharged with the sewage without causing clogging, effectively improving the sewage discharge efficiency, and no manual regular cleaning is required, reducing the difficulty of work.

[0014] 2. The utility model sets a flow meter. When there are too many debris accumulated inside the filter cartridge, the flow rate of the sewage will decrease, thereby reducing the water flow rate. When the flow rate is lower than the set value, the flow meter will automatically transmit the signal to the external supporting control terminal. The control terminal will automatically control the servo motor to drive the transmission rod and the crushing part on the transmission rod to rotate to a high degree, thereby cutting and crushing the larger debris in the filter basket. There is no need for staff to check regularly, which saves time and effort and effectively improves the sewage discharge effect of the sewage discharge device. BRIEF DESCRIPTION OF THE DRAWINGS
