Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device for environmental protection equipment. Background Art

[0002] In modern society, environmental protection is increasingly valued, especially the treatment and filtration of sewage. The filter device in sewage treatment equipment is a key component. The function of the filter device is to separate the solid particles or suspended matter in the sewage through the filter material, so as to achieve the effect of purification and filtration;

[0003] China has authorized a utility model patent to disclose a sewage filter device for environmental protection equipment (publication number: CN212236154U). The device is provided with an inclined plate to form a slope to facilitate the drainage of sewage to the outlet pipe. However, after long-term use, since sewage contains various solid particles and dissolved substances, some solid particles and soluble substances will be deposited on the surface of the inclined plate when passing through the inclined plate to form scale. When sewage flows through, part of the scale may be washed down and enter the filter with the water flow. These scale particles may block the pores of the filter, resulting in reduced filtration efficiency, and may even completely block the filter, affecting the filtration effect, making the cleaning and maintenance of the filter more frequent, increasing the maintenance workload and maintenance costs, so a filter device for environmental protection equipment is proposed to overcome the above defects. Summary of the invention

[0004] The utility model aims to solve the defect that it is inconvenient to clean dirt on the guide block used for guide in the prior art, and proposes a filtering device for environmental protection equipment.

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

[0006] A filtering device for environmental protection equipment comprises a filtering chamber and a guide plate. A rectangular frame is installed on one side of the filtering chamber, and a transmission plate is slidably matched in the rectangular frame.

[0007] A plurality of matching teeth are equidistantly arranged on the transmission plate, a scraper is installed at one end of the transmission plate, and a stopper is installed at one side of the scraper.

[0008] A motor is installed on the filter chamber, and a gear is installed on the output end of the motor.

[0009] The transmission plate cooperates with the gear through matching teeth.

[0010] A sealing block is slidably matched on one side of the guide plate.

[0011] A dirt inlet frame is installed on the guide plate, a rotating shaft is rotated on one side of the dirt inlet frame, a baffle plate is passed through the rotating shaft, and a torsion spring is connected between the dirt inlet frame and the baffle plate.

[0012] Preferably, a liquid inlet pipe penetrates the top of the filter chamber, and a liquid outlet pipe penetrates the bottom of the filter chamber.

[0013] Preferably, a filter groove is provided at the bottom of the filter chamber, and a steel mesh filter element is installed in the filter groove.

[0014] Preferably, one end of the liquid outlet pipe is located in the filter tank, and the steel mesh filter element is located on the top of the liquid outlet pipe.

[0015] Preferably, the guide plate is a wedge-shaped plate, a storage bin is provided inside the guide plate, an entrance is provided at the top of the storage bin, and the sewage inlet frame is installed at the top entrance of the storage bin.

[0016] Preferably, the sealing block is slidably fitted on one side of the storage bin, and the sealing block is slidably fitted in a side plate of the filter chamber.

[0017] The utility model has the following beneficial effects:

[0018] 1. Under the action of the scraper and the guide plate, the dirt deposited on the guide plate can be scraped off by the scraper, and the dirt can be brought to the top of the guide plate and stored in the storage bin from the entrance of the storage bin. When cleaning is needed, the sealing block can be pulled open from one side of the storage bin to clean the dirt in the storage bin, thereby ensuring the cleanliness and smoothness of the steel mesh filter element, thereby extending the service life of the steel mesh filter element, reducing the frequency of replacing the steel mesh filter element, reducing maintenance costs, and avoiding the dirt accumulated on the guide plate from being washed away and clogging the steel mesh filter element;

[0019] 2. With the cooperation of the baffle and the torsion spring, when the dirt on the guide plate does not need to be scraped off, the baffle is at the opening of the dirt inlet frame, sealing the dirt inlet frame to prevent sewage from entering the storage bin. When scraping off the dirt, the movement of the scraper drives the push rod to push the baffle open so that the dirt can enter the entrance of the storage bin from the dirt inlet frame and be stored in the storage bin. The baffle can be opened and closed in coordination when cleaning the dirt and not working, thereby increasing the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
