Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, specifically to an improved industrial wastewater purification device that is easy to use. Background Technology

[0002] Industrial wastewater includes production wastewater and industrial sewage, referring to waste liquids and waste products generated during processes. It contains industrial raw materials, intermediate products, by-products, and other waste generated during production that are lost with the wastewater. Industrial wastewater is diverse and complex in composition. For example, wastewater from the electrolytic salt industry contains mercury; wastewater from the heavy metal smelting industry contains lead, cadmium, and other metals; wastewater from the electroplating industry contains cyanide and chromium, among other heavy metals; wastewater from the petroleum refining industry contains phenols; and wastewater from the pesticide manufacturing industry contains various pesticides. Because industrial wastewater often contains multiple toxic substances, it pollutes the environment and poses a significant threat to human health. Therefore, it is essential to develop comprehensive utilization methods to turn harm into benefit, and to implement appropriate purification measures based on the composition and concentration of pollutants in the wastewater before discharge.

[0003] The filters in existing industrial wastewater treatment devices cannot remove impurities from the wastewater in a timely manner after filtering them out. Over time, this can easily lead to filter clogging, affecting the filtration effect and making them difficult to clean. In addition, some chemicals need to be added during the purification process, but these chemicals are difficult to spread over a large area in the wastewater, resulting in poor treatment efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an improved industrial wastewater purification device that is easy to use. This addresses the problems of existing industrial wastewater treatment devices where the filter screen cannot be removed promptly after filtering out impurities from the wastewater, leading to clogging over time, affecting the filtration effect, and being difficult to clean. Furthermore, the need to add chemicals during the purification process results in poor treatment efficiency because the chemicals cannot diffuse widely in the wastewater.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved industrial wastewater purification device that is easy to use includes a wastewater treatment tank. A drive motor is provided on the top end face of the wastewater treatment tank. The output end of the drive motor extends into the inner cavity of the wastewater treatment tank and is provided with a rotating shaft. Multiple evenly distributed stirring rods are provided on the rotating shaft. An annular pipe is provided on the top of the inner cavity of the wastewater treatment tank and is coaxially sleeved on the outside of the rotating shaft. Multiple high-pressure nozzles are provided at the bottom of the annular pipe and are connected thereto. A wastewater filter box is provided at the bottom of the wastewater treatment tank.

[0007] The wastewater filter box has a drain pipe on the side away from the wastewater treatment box. Inside the wastewater filter box, a barrier filter screen, a cotton layer filter screen, and an activated carbon adsorption screen are detachably installed in sequence. The activated carbon adsorption screen is located near the end of the drain pipe. On the side of the wastewater filter box away from the drain pipe, there is an installation plate. A rotary motor is installed on the installation plate. The output end of the rotary motor extends into the wastewater filter box and has a connecting shaft. A scraper is installed at the end of the connecting shaft.

[0008] As a preferred embodiment of this utility model, a water injection pipe is provided on the wastewater treatment tank on one side of the drive motor, and a chemical injection pipe connected to the annular pipe is provided on the wastewater treatment tank on the other side of the drive motor.

[0009] As a preferred embodiment of this utility model, a connecting pipe is provided between the wastewater treatment tank and the wastewater filter tank, and a control valve is provided on the connecting pipe.

[0010] As a preferred technical solution of this utility model, the bottom of the inner cavity of the wastewater filter box is provided with a water guide slope located below the connecting pipe.

[0011] By using the above technical solution and the setting of the water guide slope, wastewater is prevented from accumulating in the corner of the wastewater filter box, which facilitates the filtration treatment of wastewater.

[0012] As a preferred embodiment of this utility model, the wastewater filter box is provided with a support rod. One end of the support rod is fixedly connected to the inner side wall of the top of the wastewater filter box, and the other end of the support rod is movably connected to the connecting shaft.

[0013] By utilizing the above technical solution and the support rod, the stability of the connecting shaft driving the scraper to rotate is improved.

[0014] As a preferred technical solution of this utility model, the barrier filter screen, the cotton layer filter screen and the activated carbon adsorption screen are all provided with guide plates on both sides, and the wastewater filter box is provided with guide grooves that are adapted to the guide plates on both inner side walls.

[0015] The above technical solution, by utilizing the guide groove and guide plate, improves the stability of the barrier filter screen, cotton layer filter screen and activated carbon adsorption screen installed in the wastewater filter box.

[0016] As a preferred technical solution of this utility model, the bottom of the barrier filter screen, the cotton layer filter screen and the activated carbon adsorption screen are all provided with snap-fit ​​plates, and the bottom inner wall of the wastewater filter box is provided with snap-fit ​​grooves for the snap-fit ​​plates to be inserted.

[0017] The above technical solution, by utilizing the snap-fit ​​groove and snap-fit ​​plate, further improves the stability of the barrier filter screen, cotton layer filter screen and activated carbon adsorption screen installed in the wastewater filter box.

[0018] As a preferred embodiment of this utility model, the top of the barrier filter, the cotton layer filter, and the activated carbon adsorption mesh are all provided with a drive handle.

[0019] The above technical solution utilizes a drive handle to facilitate the disassembly and assembly of the barrier filter, cotton layer filter, and activated carbon adsorption screen by staff.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] In operation, the wastewater to be purified is injected into the wastewater treatment tank through the injection pipe. Then, the chemical solution is transported through the injection pipe into a ring-shaped pipe. Multiple high-pressure nozzles at the bottom of the ring-shaped pipe evenly spray the chemical solution. The drive motor is activated, rotating the shaft and stirring rod to uniformly mix the wastewater and chemical solution, thus increasing the efficiency and effectiveness of wastewater purification. The purified wastewater then enters the wastewater filter tank through a connecting pipe. Larger impurities are blocked by a barrier filter screen, while smaller particles are further filtered by a cotton layer filter screen. Activated carbon adsorption further filtration is performed, and finally, the filtered water is discharged from the wastewater filter tank through a drain pipe. This invention achieves a more uniform mixing of wastewater and chemical solution, thereby increasing the efficiency and effectiveness of wastewater purification and improving the filtration effect.

[0022] After prolonged use, the filter screen inside the wastewater filtration box is rotated by starting the rotary motor, which drives the connecting shaft and scraper to remove the deposits on the filter screen, thereby improving the filtration efficiency and effect of the wastewater.
