It includes a base, on which a storage tank is fixedly installed. Several filter boxes are mounted on the base, and four fixed brackets are fixedly installed inside each filter box, with two brackets forming a group. In this adjustable phosphoric acid separation and filtration device, the feed enters the filter box through the inlet and falls onto filter plate one under gravity.

Description

Technical Field

[0001] This invention belongs to the field of phosphoric acid filtration technology, specifically an adjustable phosphorus-containing wastewater separation and filtration device. Background Technology

[0002] Phosphoric acid waste liquid is industrial waste containing phosphoric acid or phosphates, mostly from chemical, metallurgical, electroplating and other production processes. Its components may include phosphoric acid, heavy metal ions, etc., and it is corrosive. If it is discharged directly without treatment, it will pollute the soil and water bodies, endanger the ecological environment and human health. It must be collected and treated in accordance with regulations to ensure that it meets the standards before being discharged or recycled.

[0003] Phosphoric acid waste liquid contains many solid impurities. In order to recycle phosphoric acid, it is necessary to separate and filter it. However, existing phosphoric acid separation and filtration devices cannot completely separate the solid impurities from the phosphoric acid waste liquid when filtering it, thus increasing the operating cost. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an adjustable phosphorus-containing wastewater separation and filtration device, which solves the problem that phosphoric acid waste liquid contains many solid impurities. In order to recycle phosphoric acid, it is necessary to separate and filter it. Existing phosphoric acid separation and filtration devices cannot completely separate the solid impurities from the phosphoric acid waste liquid when filtering it, thus increasing the operating cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable phosphorus-containing wastewater separation and filtration device, comprising a base, a storage tank fixedly installed on the base, several filter boxes installed on the base, four fixed frames fixedly installed inside the filter boxes, two fixed frames forming a group, a slot provided on the fixed frame, a filter plate one and a filter plate two respectively clamped in the slot, a plurality of filter holes one and filter holes two respectively provided on the filter plate one and filter plate two, the size of filter hole one being larger than that of filter hole two, a feed inlet provided on the filter box, a guide pipe fixedly installed on the filter box, a water pump installed on the guide pipe, and a connecting pipe one installed on the water pump.

[0006] As a further embodiment of this utility model: a discharge pipe is installed on the filter box, and a second connecting pipe is connected to the end of the first connecting pipe.

[0007] As a further embodiment of this utility model: the second connecting pipe is located inside the liquid storage tank, and a sealing ring is installed at the connection between the first connecting pipe and the second connecting pipe.

[0008] As a further embodiment of this utility model: the liquid storage tank is provided with a filling port, and a motor is installed on the liquid storage tank.

[0009] As a further embodiment of this utility model: the output shaft of the motor passes through the liquid storage tank and is connected to a rotating rod, and several stirring rods are fixedly installed on the rotating rod.

[0010] As a further embodiment of this utility model: a sealing door is installed on the filter box, and a door handle is fixedly installed on the sealing door.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This adjustable phosphoric acid separation and filtration device, through the configuration of connecting pipe two, filter plate one, guide pipe, and filter box, operates by having the operator turn on the water pump. The pump draws phosphoric acid waste liquid from the storage tank into connecting pipe two, which then flows into connecting pipe one. The liquid then passes through the water pump and guide pipe into the inlet, and finally into the filter box. Under gravity, the liquid falls onto filter plate one, where larger solid impurities are blocked and retained. The phosphoric acid waste liquid then falls again through filter holes one onto filter plate two, where smaller solid impurities are blocked and retained. The completely filtered phosphoric acid waste liquid, free of solid impurities, is discharged through the discharge pipe. This solution addresses the problem of existing phosphoric acid separation and filtration devices failing to completely separate solid impurities from phosphoric acid waste liquid, thus increasing operating costs.

[0013] This adjustable phosphoric acid separation and filtration device, equipped with a motor, rotating rod, stirring rod, and water pump, operates by having workers inject phosphoric acid waste liquid into the storage tank through the inlet. When separation and filtration of the phosphoric acid waste liquid are required, workers first turn on the motor. The motor's output shaft drives the rotating rod connected to it to rotate, and the rotation of the rotating rod drives several stirring rods installed on it to rotate. This prevents localized high concentrations caused by sedimentation from corroding the storage tank and ensures the normal operation of subsequent separation and filtration.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: an adjustable phosphorus-containing wastewater separation and filtration device, including a base 1, a storage tank 2 fixedly installed on the base 1, a feeding port 3 on the storage tank 2, a motor 4 installed on the storage tank 2, and an output shaft of the motor 4 passing through the storage tank 2 and connected to a rotating rod 6. Several stirring rods 7 are fixedly installed on the rotating rod 6. Because the motor 4 is installed, the output shaft of the motor 4 can drive the rotating rod 6 connected to it to rotate. The rotation of the rotating rod 6 drives the several stirring rods 7 installed on it to rotate, thereby preventing the storage tank 2 from being corroded by excessively high local concentration due to sedimentation, and ensuring the normal operation of subsequent separation and filtration.

[0021] Several filter boxes 5 are installed on the base 1. Each filter box 5 is equipped with a sealing door 14. A door handle 15 is fixedly installed on the sealing door 14.

[0022] The filter box 5 is equipped with a discharge pipe 13, and the end of the connecting pipe 8 is connected to the connecting pipe 9.

[0023] The second connecting pipe 9 is located inside the storage tank 2. A sealing ring 10 is installed at the connection between the first connecting pipe 8 and the second connecting pipe 9. Because of the installation of the sealing ring 10, phosphoric acid waste liquid can be prevented from seeping out at the connection between the first connecting pipe 8 and the second connecting pipe 9, thus protecting the working environment.

[0024] Four fixed brackets 17 are fixedly installed inside the filter box 5. Two fixed brackets 17 form a group. The fixed brackets 17 have slots 18. Filter plate 19 and filter plate 20 are respectively locked in the slots 18. Because filter plate 19 and filter plate 20 are locked in, larger solid impurities will be blocked by filter plate 19. Then, the phosphoric acid waste liquid falls onto filter plate 20 through filter hole 21. Smaller solid impurities in the phosphoric acid raw material that has been filtered once will be blocked by filter plate 20. The phosphoric acid waste liquid that has completely separated and filtered the solid impurities will be discharged from the discharge pipe 13. This solves the problem that the existing phosphoric acid separation and filtration device cannot completely separate the solid impurities from the phosphoric acid waste liquid, thus increasing the operating cost.

[0025] The filter plate 19 and the filter plate 20 are respectively provided with a number of filter holes 1 21 and filter holes 22. The size of filter hole 1 21 is larger than that of filter hole 22. The filter box 5 is provided with a feed inlet 16. A guide pipe 12 is fixedly installed on the filter box 5. A water pump 11 is installed on the guide pipe 12. Because of the installation of the water pump 11, the rate at which phosphoric acid waste is drawn from the storage tank 2 can be adjusted to prevent too much from being drawn at one time, which would lead to incomplete subsequent separation and filtration, thus improving the stability of the operation.

[0026] A connecting pipe 8 is installed on the water pump 11.

[0027] The working principle of this utility model is as follows: During operation, the worker injects phosphoric acid waste liquid into the storage tank 2 through the inlet 3. When it is necessary to separate and filter the phosphoric acid waste liquid, the worker first turns on the motor 4. The output shaft of the motor 4 drives the rotating rod 6 connected to it to rotate. The rotation of the rotating rod 6 drives the several stirring rods 7 installed on it to rotate. Then, the water pump 11 is turned on. The water pump 11 works to draw the phosphoric acid waste liquid in the storage tank 2 into the connecting pipe 2 9, and then into the connecting pipe 1 8 through the connecting pipe 2 9. Subsequently, it passes through... The water pump 11 and the guide pipe 12 enter the feed inlet 16, and then enter the filter box 5 through the feed inlet 16. Under the action of gravity, it falls onto the first filter plate 19. Larger solid impurities are blocked by the first filter plate 19 and remain on the first filter plate 19. Then, the phosphoric acid waste liquid falls onto the second filter plate 20 through the filter hole 21. Smaller solid impurities in the phosphoric acid raw material that has been filtered once are blocked by the second filter plate 20 and remain on the second filter plate 20. The phosphoric acid waste liquid that has completely separated and filtered the solid impurities will be discharged from the discharge pipe 13.
