Description

Technical Field

[0001] This utility model belongs to the field of zero wastewater discharge technology, and more specifically, it relates to a zero wastewater discharge filtration device. Background Technology

[0002] Water pollution is one of the major environmental problems facing my country. With the development of industry in my country, the discharge of industrial wastewater is increasing daily. Industrial wastewater that does not meet discharge standards pollutes surface water and groundwater when discharged into water bodies. Once a water body is polluted, it is not easy to restore it to its original state in a short period of time. Pollution not only makes the water quality unsuitable for drinking water and fishery use, but also increases the levels of harmful chemicals and hardness in groundwater, affecting its utilization. Therefore, wastewater needs to be pre-treated before discharge. Since wastewater contains a large number of impurities, filtration is usually essential. Filtration can effectively remove impurities, particles, suspended solids, and other contaminants from wastewater. Therefore, wastewater filtration devices are indispensable in the wastewater treatment process. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a zero-discharge wastewater filtration device, comprising a filtration tank, with an inlet and an outlet respectively located on the top surface of the filtration tank, and automatic control valves installed on the inlet and outlet. The filtration tank contains a primary filtration mechanism and a secondary filtration mechanism. The primary filtration mechanism includes a primary filtration pool located within the filtration tank, a filter screen located within the primary filtration pool, an adsorption plate located below the filter screen, and a primary water pump located between the primary filtration pool and the inlet. The secondary filtration mechanism includes a secondary filtration pool located below the primary filtration pool, a drive motor located outside the secondary filtration pool, and a filter rod located on the output shaft of the drive motor, with a filter head also provided on the filter rod.

[0005] Preferably, a secondary water pump is also provided between the secondary filtration tank and the primary filtration tank.

[0006] Preferably, a water storage tank is located below the filter head, and the water outlet is located outside the water storage tank.

[0007] Preferably, the filter head and filter rod are provided with multiple adsorption holes inside, and the filter head and filter rod are detachably connected.

[0008] Preferably, the inlet, primary filter tank, secondary filter tank and outlet are connected by a guide pipe, and the guide pipe is also equipped with several flow regulating valves.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution: a zero-discharge wastewater filtration device, including a filter tank 1. The top surface of the filter tank 1 is provided with an inlet 2 and an outlet 3, respectively. Automatic control valves 4 are installed on the inlet 2 and outlet 3. The filter tank 1 contains a primary filtration mechanism 5 and a secondary filtration mechanism 6. The primary filtration mechanism 5 includes a primary filter pool 51 located within the filter tank 1, a filter screen 52 located within the primary filter pool 51, an adsorption plate 53 located below the filter screen 52, and a primary water pump 54 located between the primary filter pool 51 and the inlet 2. The secondary filtration mechanism 6 includes a secondary filter pool 61 located below the primary filter pool 51, a drive motor 62 located outside the secondary filter pool 61, a filter rod 63 located on the output shaft of the drive motor, and a filter head 64 also provided on the filter rod 63. A secondary water pump 7 is also provided between the secondary filter pool 61 and the primary filter pool 51. A water storage tank 8 is located below the filter head 64, and the outlet 3 is located outside the water storage tank 8. The filter head 64 and filter rod 63 have multiple adsorption holes inside, and the filter head 64 and filter rod 63 are detachably connected.

The filter screen 52 and adsorption plate 53 are detachably connected.

[0019] The specific usage and function of this embodiment are as follows: First, industrial wastewater enters the guide pipe 9 through the inlet 2 and is then pumped into the primary filter tank 51 by the primary pump 54. Since the primary filter tank 51 is equipped with a filter screen 52 and an adsorption plate 53, large particulate impurities in the wastewater can be filtered and adsorbed. Then, it flows into the secondary filter tank 61 below through the secondary pump 7, and then into the motor-driven filter rod 63 and filter head 64 in the secondary filter tank 61. After further fine filtration, fine impurities and suspended solids are removed, and then the wastewater is discharged through the outlet. Simultaneously, the flow regulating valve 10 on the guide pipe 9 can flexibly adjust the water flow according to specific conditions to better facilitate filtration. Furthermore, the filter screen 52, adsorption plate 53, filter rod 63, and filter head 64 are all detachable, allowing for easy replacement and cleaning, thus ensuring better filtration.
