Description

Technical Field

[0001] This utility model relates to the field of waste acid water treatment technology, and in particular to a filtration device for waste acid water treatment. Background Technology

[0002] Industrial wastewater generated during enterprise production contains acid radicals and is acidic. In order to meet national environmental protection emission requirements, a series of treatments are required. First, pretreatment steps, such as screening and sedimentation, are used to remove large particulate impurities and suspended solids from the wastewater to prevent clogging of subsequent treatment equipment.

[0003] In the process of treating waste acid water, impurities in the waste water are first filtered through a filter screen. However, after long-term use, the filter screen is prone to clogging and needs to be cleaned manually and regularly, which increases the labor intensity of the staff. Moreover, during manual cleaning, the staff may come into contact with waste acid water, which poses a threat to their health. Therefore, we propose a filtration device for treating waste acid water. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a filtration device for treating waste acid water.

[0005] This utility model is achieved by the following technical solution: a filtration device for treating waste acid water, including a treatment box, a filter frame is provided inside the treatment box, a drain pipe is connected to the right end of the treatment box, a cleaning component is provided at the left end of the treatment box, a stirring component is provided inside the treatment box, and a liquid delivery component is provided at the front end of the treatment box.

[0006] The cleaning assembly includes an extension plate, a first motor fixedly connected to the left end of the extension plate, a lead screw rotatably connected to the inner wall of the extension plate, a mounting base threaded onto the surface of the lead screw, a fixed connection between the top of the mounting base and the bottom of the filter frame, a fixed block fixedly connected to the bottom of the filter frame, a limit rod slidably connected to the inner wall of the fixed block, a water tank at the bottom of the extension plate, a first water pump fixedly connected to one end of the water tank, a water pump connected to the bottom of the first water pump and a water delivery pipe connected to the top of the first water pump, a connecting pipe connected to the end of the water delivery pipe away from the first water pump, a plurality of connecting pipes, a plurality of spray pipes connected between the plurality of connecting pipes, and a plurality of spray nozzles connected to the bottom of the spray pipes.

[0007] The above technical solution involves a first motor driving a lead screw to rotate. Since the lead screw is threadedly connected to the mounting base, it moves the filter frame to the outside of the treatment tank. Then, the first water pump is activated, drawing water from the tank through a pumping pipe and delivering it to a connecting pipe. This connecting pipe then delivers the water to spray pipes at different locations, which spray the water through several nozzles to clean the filter frame. This eliminates the need for manual cleaning, reducing the workload for workers. The cleaned water flows back into the tank, achieving water recycling. A drain pipe is connected to an external pipeline, and the treated waste acid water is discharged into the external pipeline through the drain pipe. A valve is installed inside the drain pipe to isolate the waste acid water. A pH sensor is also installed at the bottom of the treatment tank to detect the acidity or alkalinity of the waste acid water.

[0008] As a further improvement to the above solution, the right end of the extension plate is fixedly connected to the left end of the processing box, the output end of the first motor is fixedly connected to the left end of the lead screw, the right end of the lead screw is rotatably connected to the inner wall of the processing box, the two ends of the limiting rod are fixedly connected to the inner walls of the processing box and the extension plate respectively, the end of the water pump away from the first water pump extends into the interior of the water tank, and the two ends of the spray pipe are fixedly connected to the inner wall of the extension plate.

[0009] With the above technical solution, when the filter frame moves, the fixed block will slide along the limiting rod. The limiting rod limits the fixed block, ensuring stability during the movement and providing support for the filter frame.

[0010] As a further improvement to the above solution, the stirring assembly includes a second motor, the output end of the second motor is fixedly connected to a hollow rod, the surface of the hollow rod is provided with a plurality of liquid outlet holes, the surface of the hollow rod is fixedly connected with a plurality of stirring blades, and one end of the hollow rod is rotatably connected to a rotating block.

[0011] The above technical solution uses a second motor to drive a hollow rod to rotate, which in turn causes several stirring blades to rotate. The rotation of the stirring blades mixes the waste acid water with the alkaline solution, improving the neutralization reaction efficiency and thus increasing the treatment efficiency.

[0012] As a further improvement to the above solution, the front end of the second motor is fixedly connected to the rear end of the processing box, and the surface of the hollow rod is rotatably connected to the inner wall of the processing box.

[0013] As a further improvement to the above solution, the rotating block is connected to the hollow rod, and the rotating block is located at the front end of the processing box.

[0014] With the above technical solution, the interior of the rotating block is hollow, allowing the alkaline solution to enter and be transported to the interior of the hollow rod.

[0015] As a further improvement to the above solution, the liquid delivery assembly includes a liquid storage tank, a second water pump is fixedly connected to the front end of the liquid storage tank, one end of the second water pump is connected to a liquid extraction pipe, the end of the second water pump away from the liquid extraction pipe is connected to a liquid delivery pipe, the end of the liquid delivery pipe away from the second water pump is connected to a fixed pipe, and a one-way valve is fixedly installed on the inner wall of the fixed pipe.

[0016] The above technical solution stores the alkaline solution in a storage tank, which facilitates its use in the subsequent mixed treatment of waste acid water. The second water pump draws the alkaline solution from the storage tank through a suction pipe, delivers it to the inside of a fixed pipe through a delivery pipe, and then delivers the alkaline solution to the inside of a hollow rod through the fixed pipe. Finally, the alkaline solution is sprayed out through several outlet holes.

[0017] As a further improvement to the above solution, the rear end of the liquid storage tank is fixedly connected to the front end of the processing tank, one end of the liquid extraction pipe extends into the interior of the liquid storage tank, an inlet pipe is provided on the top of the liquid storage tank, and the end of the fixed pipe away from the liquid delivery pipe is connected to the rotating block.

[0018] The above technical solution allows for easy addition of alkaline solution to the storage tank via the inlet pipe. Since the rotating block is rotatably connected to the hollow rod, the rotation of the hollow rod does not cause the fixed pipe to rotate, thus not affecting the liquid delivery. Furthermore, the one-way valve effectively prevents waste acid water from entering the delivery pipe, avoiding any impact on the second water pump.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention features a cleaning component. Specifically, a first motor drives a lead screw to rotate. Since the lead screw is threadedly connected to the mounting base, it moves the filter frame to the outside of the treatment tank. Then, a first water pump is activated. The first water pump draws water from the tank through a pumping pipe and delivers it to a connecting pipe through a delivery pipe. The connecting pipe then delivers the water to spray pipes at different locations. Finally, several nozzles spray the water to clean the filter frame. This eliminates the need for manual cleaning, reducing the workload of workers. The cleaned water flows back into the tank, achieving water recycling.

[0021] This invention utilizes a stirring assembly and a liquid delivery assembly. Specifically, a second motor drives a hollow rod to rotate, causing several stirring blades to rotate. This opens a one-way valve and starts a second water pump. The second water pump draws alkaline solution from the storage tank through a suction pipe and delivers it to a fixed pipe through a delivery pipe. The fixed pipe then delivers the alkaline solution to the hollow rod, where it is sprayed out through several outlet holes. Because the hollow rod is constantly rotating, the alkaline solution can be sprayed to different locations. Furthermore, the rotation of the stirring blades mixes the waste acid water with the alkaline solution, improving the neutralization reaction efficiency and thus enhancing the treatment efficiency.

When the second motor 501 is started, the second motor 501 drives the hollow rod 502 to rotate, causing the stirring blades 504 to rotate. The rotation of the stirring blades 504 mixes the waste acid water with the alkaline solution, improving the neutralization reaction efficiency and thus improving the treatment efficiency.

The alkaline solution is then delivered to the inside of the hollow rod 502 through the fixed pipe 604 and sprayed out through several outlet holes 503.

[0038] The rear end of the storage tank 601 is fixedly connected to the front end of the processing tank 1. One end of the liquid extraction pipe extends into the interior of the storage tank 601.

[0039] The implementation principle of a filtration device for treating waste acid water in this embodiment is as follows: First, cleaning water is added to the water tank 407, and an alkaline solution is added to the storage tank 601. Then, waste acid water is added to the treatment tank 1. Impurities in the waste water are filtered through the filter frame 2. The filtered acid water enters the bottom of the treatment tank 1. Then, the second motor 501 is started, driving the hollow rod 502 to rotate, causing several stirring blades 504 to rotate. The one-way valve 605 is opened, and the second water pump 602 is started. The second water pump 602 draws the alkaline solution from the storage tank 601 through the extraction pipe and delivers it to the fixed pipe 604 through the delivery pipe 603.

The liquid can be sprayed to different locations, and the rotation of the stirring blade 504 mixes the waste acid water with the alkaline solution, improving the neutralization reaction efficiency and thus improving the treatment efficiency. When the filter frame 2 needs to be cleaned, the first motor 402 is started, which drives the lead screw 403 to rotate. Since the lead screw 403 is threadedly connected to the mounting base 404, it moves the filter frame 2 to the outside of the treatment box 1. Then, the first water pump 408 is started. The first water pump 408 draws water from the water tank 407 through the water pumping pipe 409 and delivers it to the inside of the connecting pipe 411 through the water delivery pipe 410. The water source is delivered to the spray pipes 412 at different locations through the connecting pipe 411. Then, the water source is sprayed out through several nozzles 413 to clean the filter frame 2. No manual cleaning is required, which reduces the labor intensity of the staff. The cleaned water flows into the inside of the water tank 407, realizing the recycling of water source.
