Description

A pretreatment device for wastewater reuse

Technical Field

The utility model relates to the technical field of wastewater reuse pretreatment, in particular to a wastewater reuse pretreatment device.

Background Art

The steel cold rolling wastewater reuse pretreatment softening treatment device is a device commonly used to treat steel cold rolling wastewater. Softening treatment refers to the conversion of hardness ions in wastewater into insoluble precipitates through a series of physical and chemical reactions to reduce the hardness of water. By converting hardness ions in wastewater into precipitates and removing suspended matter and particulate matter, the water quality of steel cold rolling wastewater can be improved. This pretreatment device can make wastewater meet the standards for reuse, provide a sustainable source of water, and reduce the impact on the environment.

At present, the patent with announcement number CN216584529U discloses a wastewater reuse pretreatment device, and its technical points are: it includes a box-shaped pretreatment tank with openings at the top, bottom and side bottoms, the bottom of the pretreatment tank is sealed with a base, a support frame is installed on the top of the base, a motor is installed on the side of the pretreatment tank, the output shaft of the motor is located inside the pretreatment tank and an agitator is installed, and the base extends toward the side opening of the pretreatment tank and is provided with a mesh plate-shaped filter. Although the above device solves the problem that suspended matter can be efficiently and quickly filtered out of steel cold rolling wastewater after the dosing reaction, thereby improving the pretreatment efficiency of steel cold rolling wastewater, there is still a problem that the filter cannot be replaced, resulting in blockage of the drain outlet.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

As shown in Figures 1 to 3, a pretreatment device for wastewater reuse includes a box body 1 and a stirring fan 9 connected to the inside of the box body 1. A lower water bucket 2 is fixedly connected to the bottom of the box body 1, and the lower water bucket 2 is communicated with the bottom of the box body 1. An L-shaped pipe 3 is fixedly connected to the bottom of the lower water bucket 2, and the lower water bucket 2 is connected to the L-shaped pipe 3. A filter device 4 is fixedly connected to the other end of the L-shaped pipe 3, and the L-shaped pipe 3 is connected to the pot device. A drain outlet 6 is fixedly connected to the other side of the filter device 4, and the filter device 4 is connected to the drain outlet 6.

As shown in Figure 1, a pretreatment device for wastewater reuse in the utility model is similar in structure to an existing pretreatment device for wastewater reuse, such as the pretreatment device for wastewater reuse disclosed in the patent with announcement number CN216584529U. The main improvement of the utility model is to prevent the drain port from being blocked and simplify the replacement of the filter cotton net structure. As shown in Figures 1 to 3, when the pretreatment device for wastewater reuse in the utility model is in use, wastewater enters the interior of the box 1, and the operator turns on the stirring fan 9 to stir evenly after adding a softener. After the water and medicine are mixed, they are allowed to stand for a period of time. After the wastewater is coagulated and precipitated, the valve 7 is opened. After the treated wastewater passes through the L-shaped pipe 3, the wastewater enters the drain port 6 through the filter device 4, and the sediment in the wastewater falls from the connection point of the lower water bucket 2 and will not be deposited inside the box 1, and the particulate matter is blocked outside the filter device 4, and the operator can collect the wastewater from the drain port 6 for reuse.

As shown in Figures 2 and 3, the filtering device 4 includes two connecting plates 401 that are tightly connected and a filter cotton net 501 that is slidably connected to the connecting plates 401. A filter cotton channel 403 is opened on the top of the two connecting plates 401 that are tightly connected. A waterproof rubber pad frame 5 that is slidably connected to the filter cotton channel 403 is fixedly connected to the outside of the filter cotton net 501.

Specifically, the filter cotton channel 403 of the filter device 4 is slidably connected to the waterproof rubber pad frame 5, and the waterproof rubber pad frame 5 can prevent waste water from seeping out of the filter cotton channel 403, thereby increasing the waterproof function of the equipment, and the operator can remove the filter cotton net 501 from the filter device 4 for replacement after closing the valve 7.

As shown in FIG. 2 and FIG. 3 , a water outlet 402 is provided on the surface of two connecting plates 401 that are closely connected.

Specifically, through this arrangement, wastewater can flow from the L-shaped pipe 3 through the water outlet 402 and into the drain outlet 6, and a filter cotton net 501 is installed at the water outlet 402 to intercept particulate matter in the wastewater, thereby improving the functionality of the equipment.

As shown in FIGS. 2 and 3 , bolts 404 are threadedly connected to the surface of the connecting plate 401 .

Specifically, through this arrangement, two symmetrical connecting plates 401 can be fixed together by bolts 404 to prevent loosening and leakage of wastewater. When cleaning the pipeline, the connecting plates 401 can be disassembled by turning the bolts 404, which makes it convenient for operators to clean the inside of the connecting plates 401, thereby improving the convenience of the filtering device 4.

As shown in FIGS. 2 and 3 , a handle 502 is fixedly connected to the top of the waterproof rubber pad frame 5 .

Specifically, through this arrangement, the operator can pull the handle 502 to remove the filter cotton mesh 501 and the waterproof rubber pad frame 5 from the filter cotton channel 403, which is convenient for the operator to replace the filter cotton mesh 501 and improves the convenience of the equipment.

As shown in FIG. 1 , an observation window 8 is provided on the surface of the box body 1 .

Specifically, with this arrangement, the operator can see the degree of mixing of water and medicine inside the box 1 through the observation window 8 and discharge the waste water, thereby improving the functionality of the equipment.

As shown in FIG. 1 , a valve 7 is fixedly connected to the outside of the L-shaped tube 3 , and the valve 7 is in communication with the L-shaped tube 3 .

Specifically, through this arrangement, the operator can close the valve 7 to perform wastewater coagulation operation, and can also open the valve 7 to discharge the wastewater, which makes it convenient for the operator to control the softening treatment of the wastewater at any time, thereby improving the convenience of the equipment.
