The filter plate is tightly attached to the scraping plate, so that fixed materials on the filter plate can be conveniently scraped; when the filter plate moves upwards to the highest point, a sliding block drives a fixed substance on a scraping plate to extrude an overturning plate to enable the overturning plate to be overturned and opened, the fixed substance falls into a collecting groove, at the moment, a half gear rotates to one side without teeth, and when the half gear cannot be meshed with clamping teeth in an adjusting frame, the filter plate suddenly descends to the initial position; and the sliding block also returns to the initial position through the reciprocating screw rod, so that low working efficiency of the filtering device caused by incapability of cleaning the filtering plate in time is avoided.

Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, in particular to an environmental wastewater filtering device. Background Art

[0002] Traditional wastewater treatment goes through multiple processes, all of which prioritize coarse filtration of wastewater to remove larger particles, and then chemically treat the wastewater to remove harmful substances in the wastewater to meet discharge standards. Some sewage contains too many impurities, and the impurities in the wastewater need to be removed, so a filtration device is needed to filter it.

[0003] When traditional environmental wastewater filtering devices filter wastewater, the filter screen is often fixed there. When filtering the wastewater, solid matter in the wastewater will remain on the filter screen, which will easily cause the filter screen to reduce the filtering speed of the wastewater. If the filter screen is not cleaned in time, the working efficiency of the filtering device will be low. In order to solve the above problems, we proposed an environmental wastewater filtering device. Utility Model Content

[0004] The purpose of the utility model is to provide an environmental wastewater filtering device to solve the existing problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is an environmental wastewater filtering device, comprising a filter box, wherein support platforms are arranged on both sides of the bottom of the filter box, springs are arranged on both sides of the upper surface of the support platform, a filter plate is arranged on the upper end of the spring, an adjustment frame is arranged on one side of the upper surface of the filter plate, and a plurality of latch teeth are arranged on one surface of the adjustment frame;

[0007] A servo motor is provided on one side of the filter box, a reciprocating screw is provided on one surface of the servo motor, a half gear is fixedly connected to the peripheral side of the reciprocating screw, the reciprocating screw passes through the filter box and the adjustment frame, a slider is threadedly connected to the peripheral side of the reciprocating screw, a movable tube is provided on the lower surface of the slider, an extrusion spring is provided in the movable tube, a movable column is provided at one end of the extrusion spring, and a scraper is fixedly connected to the lower end of the movable column;

[0008] A flip plate is hingedly connected to the other side of the filter box, and a water outlet is arranged on the lower side of one surface of the filter box.

[0009] Furthermore, the shape and size of the filter box are adapted to the filter plate, and the filter plate and the filter box cooperate with each other.

[0010] Furthermore, the half gear is a gear structure with only half teeth, the shape and size of the half gear are adapted to the latch teeth, and the half gear is meshed with the latch teeth.

[0011] Furthermore, the shape and size of the movable column are adapted to the movable tube, and the movable column and the movable tube are nested with each other.

[0012] Furthermore, the shape and size of the scraper are adapted to the filter box, and the scraper and the filter box cooperate with each other.

[0013] Furthermore, a slide groove is provided on one surface of the filter box, a collecting groove is provided in the slide groove, a handle is provided on one surface of the collecting groove, and the position of the collecting groove is adapted to the flip plate.

[0014] The utility model has the following beneficial effects:

[0015] The utility model turns on the servo motor to drive the reciprocating screw rod to rotate. When the reciprocating screw rod rotates, the half gear also rotates accordingly, making it mesh with the tooth in the adjusting frame, driving the filter plate to move up. At the same time, the reciprocating screw rod cooperates with the thread of the slider to move along the reciprocating screw rod toward the flip plate direction. When the filter plate moves up, the extrusion scraper makes the movable column squeeze the extrusion spring retract into the movable tube. At this time, the filter plate and the scraper are tightly fitted, which is convenient for scraping the fixed materials on the filter plate. When the filter plate moves to the highest point, the slider drives the fixed materials on the scraper plate to squeeze the flip plate to make it flip open, and the fixed materials will fall into the collecting tank. At this time, the half gear rotates to the side without teeth, and when the half gear cannot mesh with the tooth in the adjusting frame, the filter plate suddenly drops to the initial position, and the slider also returns to the initial position through the reciprocating screw rod, completing the cleaning of the filter plate, avoiding the failure to clean the filter plate in time, resulting in low working efficiency of the filtering device.
