Description

Technical Field

[0001] The utility model belongs to the field of water purification and relates to a filtering device for purifying water quality. Background Art

[0002] Direct discharge of industrial wastewater can easily lead to the death or even extinction of aquatic animals and plants. Industrial wastewater may also seep into groundwater, causing groundwater pollution, and then leading to crop pollution. If surrounding residents use polluted surface water or groundwater as domestic water, it will endanger their health and cause the death of users after long-term drinking. Industrial wastewater seeps into the soil, causing soil pollution and affecting the growth of plants and microorganisms in the soil. Industrial sewage includes floating solid pollutants and suspended impurity particles. Among them, the volume of floating solid pollutants is relatively large, while the volume of suspended impurities is relatively small. Therefore, it is necessary to treat floating solid pollutants and suspended impurity particles separately. Currently, impurities are treated by sewage treatment equipment, but during the treatment process, the floating solids are not removed in time after screening, resulting in easy blockage of the treatment box. In addition, the combination effect of suspended impurities and flocculants is poor, and the sludge is easily pumped away during the extraction of the separated clear water. Therefore, in order to solve the above technical problems, the technical solution of this application is set. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a filtering device for purifying water quality, which solves the above technical problems.

The pumping mechanism floating on the water surface of the second box body is used to pump the water, so as to pump the clear water inside the second box body, avoiding the problem in the prior art that part of the precipitate and sludge are pumped away together by a submersible pump. After the clear water is pumped out, the drain pipe is opened to convey the water-containing precipitate to a drying and wet separation machine for further separation.

[0008] Further: The filtering structure includes a filtering tank. The inside of the filtering tank is provided with a space for temporarily storing floating impurities and water and is open at the upper end.

[0009] Further: One end of the conveying pipe is communicated with the bottom of the inner wall of the first box body, and the other end of the conveying pipe is communicated with the upper part of the second box body. A first on-off valve is communicated between the conveying pipes.

[0010] Further: The shape of the middle and lower parts of the inner wall of the second box body is a cylinder, and the shape of the bottom of the inner wall of the second box body is a cone. A second on-off valve is communicated between the drain pipes, and the second on-off valve is located on one side close to the bottom of the second box body.

[0011] Further: The mixing mechanism includes a horizontally arranged support frame. The two sides of the support frame are respectively connected to the top of the second box body. A driving motor arranged vertically downward is provided on the support frame. The driving motor is connected to the upper end surface of the support frame through a number of support columns. A driving shaft is connected inside the driving motor. A through hole for the driving shaft to pass through is provided on the support frame. The lower end of the driving shaft is connected with a mixing shaft, and the lower end of the mixing shaft is connected with a mixing blade group. The mixing blade group is located at the bottom of the inner wall of the second box body.

[0012] Further: The pumping mechanism includes a floating box body. A water pump is connected to the upper end surface of the floating box body. One end of the water pump is communicated with a water suction pipe, the lower end of the water suction pipe is flush with the lower end surface of the floating box body, the upper end of the water pump is communicated with a drain pipe, and the upper end of the drain pipe is located outside the second box body.

[0013] Further: The bottom of the first box body is connected to the foundation, the lower end surface of the second box body abuts against the foundation through a plurality of support feet, and the bottom of the first box body is located above the upper part of the second box body.

[0014] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0015] 1. For the filtration equipment for purifying water quality, by often removing the filtration structure to pour out the floating solids, the problem that the first box body is prone to blockage caused by the failure to timely remove the floating solids after screening in the prior art is avoided;

[0016] 2.

The size and shape of the filtering structure match the size and shape of the inner wall of the first box body 1. On one side of the first box body 1, there is a second box body 2. The second box body 2 is located below the first box body 1. The second box body 2 is communicated with the first box body 1 through a conveying pipe 3. Inside the second box body 2, there is a space for re-filtering the water body and the upper end is open. A mixing mechanism is connected to the top of the second box body 2. The lower end of the mixing mechanism is located at the bottom of the inner wall of the second box body 2. A pumping mechanism floats on the water surface inside the second box body 2. The upper end of the pumping mechanism is located outside the second box body 2. The bottom of the second box body 2 is communicated with a discharge pipe 4.

[0026] The specific implementation method of this embodiment is as follows: The first box body and the second box body are both arranged vertically and the second box body is located below the first box body, so that the water body filtered by the first box body directly flows into the second box body. The filtering structure arranged inside the first box body is used for screening floating solids and water body. The screened water body enters the second box body through the conveying pipe, while the floating solids remain inside the filtering structure. Then, by frequently removing the filtering structure, the floating solids can be poured out, avoiding the problem that the first box body is easily blocked due to the failure to remove the floating solids in time after screening in the prior art.

[0027] When the water body enters the second box body, pour the flocculant from the top of the second box body, and then start the mixing mechanism to work. The mixing mechanism drives the water body and the flocculant to be fully mixed. After the flocculant combines with the suspended impurities to form precipitation, it falls to the bottom of the second box body. The pumping mechanism floating on the water surface in the second box body is used to pump the water body, so as to pump the clear water inside the second box body, avoiding the problem in the prior art that part of the precipitation and sludge are pumped away together by a submersible pump. After the clear water is pumped out, open the discharge pipe to transport the water-containing precipitate to a drying and separation machine for further separation.

A number of screening holes 6 for the water body to pass through are evenly distributed on the filtering tank 5. A number of hanging rings 7 are connected to the top of the filtering tank 5.

[0030] One end of the conveying pipe 3 is communicated with the bottom of the inner wall of the first box body 1, the other end of the conveying pipe 3 is communicated with the upper part of the second box body 2, and a first on-off valve 8 is communicated between the conveying pipes 3.

[0031] The upper, middle and lower parts of the inner wall of the second box body 2 are cylindrical, and the bottom of the inner wall of the second box body 2 is cone-shaped. The discharge pipe 4 is connected with a second on-off valve 9, and the second on-off valve 9 is located on one side close to the bottom of the second box body 2.

[0032] The specific implementation method of this embodiment is: the lower end surface of the top of the filter tank is used to fit with the top of the first box body, so that the filter tank is placed above the first box body, and at the same time, the floating impurities and the water body are screened through the screening holes. When a large amount of floating impurities are accumulated inside the filter tank, the entire filter tank can be removed from the first box body by inserting the hanging ring with a forklift, thereby facilitating the removal of the floating impurities inside the filter tank.

[0033] By opening the second on-off valve, the delivery pipe delivers the water preliminarily filtered in the first box to the inside of the second box. When the water in the second box is mixed with the flocculant, the first on-off valve is closed.
