Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an environmentally friendly chemical wastewater treatment device. Background Technology

[0002] A search revealed that Chinese patent publication number CN222159784U discloses an environmentally friendly chemical wastewater treatment device. Although the device uses a cleaning brush to scrape off and loosen the clumps of flocs at the bottom of the filter plate and then cleans the bottom of the filter plate, thus achieving an automatic cleaning function and greatly extending the service life of the treatment tank, the cleaning brush can only clean the flocs on the surface of the filter plate. The cleaning brush cannot thoroughly clean the small flocs inside the filter plate, which still poses a risk of clogging. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an environmentally friendly chemical wastewater treatment device that solves the problem mentioned in the background art that existing devices cannot thoroughly clean the flocs inside the filter plates, resulting in the risk of clogging.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An environmentally friendly chemical wastewater treatment device includes a tank, a second pressure chamber, a second piston, and a ejector pin. A wastewater inlet is located on one side of the bottom of the tank, communicating with the interior of the tank. A chemical inlet is located above the wastewater inlet, communicating with the interior of the tank. A pressure relief pipe is connected to the other side of the tank, with one end of the pressure relief pipe communicating with the interior of the first pressure chamber. A first piston is located inside the first pressure chamber, with a first spring at its top. One end of the first piston's top communicates with the bottom of a connecting pipe, the other end of which communicates with the interior of the second pressure chamber. A second piston is located inside the second pressure chamber, with an ejector pin embedded at its bottom. One end of the ejector pin's bottom is inserted into a partition plate, which is connected to the inner wall of the tank. A filter plate is located below the partition plate, communicating with the inner wall of the tank. A drain outlet is located on one side of the top of the tank, communicating with the interior of the tank. A door is located on one side of the tank for cleaning the interior of the tank.

[0005] Preferably, a limiting ring is provided inside the second pressure chamber. The limiting ring is welded to the inner wall of the second pressure chamber, and the limiting ring helps to limit the upward movement stroke of the second piston.

[0006] Preferably, the top of the second piston is connected to one end of the bottom of the slide rod, the outer wall of the slide rod slides in contact with the top of the second pressure chamber, and a protruding structure is provided at one end of the top of the slide rod. A second spring is fitted on the outside of the slide rod, and the slide rod is driven to move upward by the second spring, thereby enabling the slide rod to drive the second piston to move upward and reset.

[0007] Preferably, one end of the ejector pin has a conical shape, and the ejector pin is inserted into the filter plate through a lifting and lowering mechanism. The number of ejector pins corresponds to the holes and grooves on the surface of the filter plate. The outer wall of the ejector pin has a prismatic structure to ensure that there is a flow space between the outer wall and the filter plate when the ejector pin is inserted into the filter plate.

[0008] Preferably, a drive motor is installed at the bottom of the tank, and a stirring blade is fitted outside the output end of the drive motor. The outer wall of the stirring blade slides in contact with the inner wall of the tank. Under the action of the drive motor, the drive motor can drive the stirring blade to rotate, so that the medicine can react quickly and fully with the sewage.

[0009] This utility model provides an environmentally friendly chemical wastewater treatment device. It has the following beneficial effects:

[0010] (1) This environmentally friendly chemical wastewater treatment equipment, when in use, wastewater and chemical solution slowly and continuously enter the tank through the chemical solution inlet and wastewater inlet, and then the flocculant solution reacts with the wastewater. Due to the action of the filter plate, the flocs can be intercepted inside the tank, and then the treated wastewater can pass through the filter plate and be discharged through the drain outlet. When the filter plate is blocked, due to the continuous input of chemical solution and wastewater into the tank, the internal pressure of the tank increases, which will push the first piston. Then the air in the cavity above the first piston will be compressed and transported to the second pressure chamber through the connecting pipe. When the pressure inside the second pressure chamber increases, it will push the second piston, which will drive the ejector pin to move downward, so that the ejector pin can be inserted into the filter plate and push out the flocs inside the filter plate. After the flocs inside the filter plate are pushed out, the second piston can be reset under the action of the second spring, so that the device can automatically clean the filter plate when blocked, which helps to avoid the filter plate from being blocked during filtration.

[0011] (2) In this environmentally friendly chemical wastewater treatment equipment, after the chemical solution and wastewater enter the tank, the drive motor drives the stirring blades to rotate, so that the chemical solution can react quickly and fully with the wastewater. At the same time, the stirring blades can scrape and clean the inner wall of the tank, which helps to keep the inner wall of the tank clean.

[0012] This solves the problem that existing devices cannot thoroughly clean the flocs inside the filter plates, thus still posing a risk of clogging. Attached Figure Description
