Description

Technical Field

[0001] This utility model relates to the field of liquid purification equipment technology, and in particular to a liquid purification equipment based on negative pressure paper tape filtration technology. Background Technology

[0002] In fields such as machining, metal processing, and chemical engineering, liquids often contain impurities such as solid particles and oil. Traditional filtration methods, such as screen filtration and centrifugal separation, suffer from problems such as low filtration accuracy, low filter media utilization, insufficient automation, and high operating costs.

[0003] While negative pressure filtration technology has some applications in the existing technology, there is still considerable room for improvement in areas such as automatic filter cloth replacement, negative pressure stability, and system integration. Therefore, we propose a liquid purification device based on negative pressure paper tape filtration technology to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing a liquid purification device based on negative pressure paper tape filtration technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A liquid purification device based on negative pressure paper tape filtration technology includes a water tank body, an electrical control box on the front of the water tank body, a chip collection cart at the end of the water tank body, a filter box at the top of the water tank body, a movable cover at the end of the filter box, a nitrogen spring at the end of the movable cover, the movable cover being directly above the chip collection cart, a centrifugal pump on the side of the filter box, a gas-liquid mixing pump on the front of the water tank body, a circulating filter cloth inside the filter box (the circulating filter cloth is inclined), and a negative pressure fan at the top of the filter box, the negative pressure fan being connected to the filter box.

[0007] The system allows the waste liquid to enter the interior of the filter housing, so that the liquid comes into contact with the circulating filter cloth. The centrifugal pump then draws in the gas inside the main body of the water tank, thereby filtering the liquid through the circulating filter cloth, which then accumulates on the circulating filter cloth to form a filter cake.

[0008] Preferably, the end of the gas-liquid mixing pump body is provided with two sets of pipes, one set of pipes is connected to the inside of the filter box, and the other set of pipes is connected to the liquid inside the water tank body;

[0009] The gas-liquid mixing pump can drive the liquid inside the water tank into the filter box, thereby cleaning the circulating filter cloth and improving its performance.

[0010] Preferably, a first power box is provided on one side of the end of the filter box, and a second power box is provided on the other side of the end of the filter box. A speed reducer is provided inside the first power box, and the output end of the speed reducer is connected to the rotating shaft at the end of the circulating filter cloth.

[0011] The speed reducer can drive the circulating filter cloth to rotate, which in turn drives the filter cake to rotate, thus forming a circulation of the filter cloth and allowing for better cleaning of the filter cake on the filter cloth.

[0012] Preferably, the second power box is provided with two sets of sprockets. One set of sprockets is connected to the shaft at the end of the circulating filter cloth, while the end of the other set of sprockets extends into the interior of the filter box and is connected to the roller brush. The two sets of sprockets are connected by a chain.

[0013] The circulating filter cloth can be rotated slowly by the sprocket driving the drum brush, which in turn can clean the filter cake.

[0014] Preferably, the roller brush is located below the circulating filter cloth, and a chip guide plate is provided on the end side of the filter box. The chip guide plate is inclined, and both the roller brush and the chip guide plate are located directly above the chip collection cart.

[0015] This allows impurities cleaned by the roller brush to fall into the inside of the chip collection cart, making it easier to clean up the impurities.

[0016] Preferably, the inner end of the filter box is provided with an installation shell, and the inside of the filter box is provided with a rubber pressure plate, which is located above the circulating filter cloth;

[0017] The rubber plate can block the top of the circulating filter cloth, causing impurities to accumulate and form a cake. When it comes into contact with the rubber plate, it is pressed down. At the same time, the rubber plate moves and drives the reducer to rotate through the electrical control box, forming a linkage.

[0018] Preferably, a filter tank is provided inside the mounting housing, and filter cotton is provided inside the filter tank. The bottom end of the filter cotton is connected to the interior of the water tank body through a pipe.

[0019] The cleaned liquid can enter the interior of the filter tank after passing through the outer casing, and then the impurities filtered by the filter cotton enter the interior of the water tank body through the pipe.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model allows the waste liquid to be poured from the top of the filter box into the interior of the circulating filter cloth. After the centrifugal pump is turned on, a negative pressure is formed inside the filter box, which allows the liquid to pass through the circulating filter cloth for filtration. The remaining impurities then pile up on the circulating filter cloth to form a cake. The reducer then drives the circulating filter cloth to rotate, so that the circulating filter cloth circulates and completes the cleaning of impurities, resulting in better performance of the circulating filter cloth.

[0022] 2. The gas-liquid mixing pump of this utility model can drive the liquid inside the water tank body into the filter box, so that the cleaning liquid comes into contact with the circulating filter cloth. Then the cleaned liquid enters the housing, and is filtered through the filter tank and filter cotton. Then it flows back into the water tank body for reuse. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figure 1-6 The liquid purification device shown is based on negative pressure paper tape filtration technology. A filter box 4 is installed at the top of the main body 1 of the water tank. An electrical control box 2 is then fixedly installed on the front side of the main body 1. A movable cover 9 is hinged to the end of the filter box 4. A nitrogen spring 10 is movably installed inside the movable cover 9, allowing the nitrogen spring 10 to push the movable cover 9 open. A chip collection cart 3 is placed below the movable cover 9, and the cart moves via wheels. Centrifugal pumps 5 (model CDLK15-8 / 2SWPC) are connected to both sides of the end of the filter box 4 via pipes. A gas-liquid mixing pump 6 (model 50KFD-12) is fixedly installed on the side of the centrifugal pump 5. Two sets of pipes are connected to the end of the gas-liquid mixing pump 6; one set connects to the interior of the filter box 4, and the other set connects to the liquid inside the main body 1 of the water tank. Spray nozzles are installed at both ends of the circulating filter cloth 13, connecting the nozzles to the pipes on the gas-liquid mixing pump body 6 that connect to the inside of the filter box 4. Water from inside the water tank body 1 is then injected into the filter box 4 through the pipes and spray nozzles, cleaning the surface of the circulating filter cloth 13. Rotary shafts are then installed at both ends inside the filter box 4, and the circulating filter cloth 13 is fitted onto the outside of these shafts. The circulating filter cloth 13 is angled. Meanwhile, a fixed installation is also made inside the water tank body 1. A rubber pressure plate 18 is located above the circulating filter cloth 13. A roller brush 20 is installed at the end of the filter box 4 via a rotating shaft. The roller brush 20 is located below the end of the circulating filter cloth 13 and inside the movable cover plate 9. A negative pressure fan 11 is then fixedly installed at the top of the filter box 4. The negative pressure fan 11 can be model 2HB410-7AH16. The end of the negative pressure fan 11 is connected to the inside of the filter box 4 via a pipe.

[0032] For a detailed description of the roller brush 20 in this embodiment, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 6A reducer 14, model NMRV50 / 100-63B5-0.18KW-V6, is fixedly installed inside the first power box 7, so that the output end of the reducer 14 is connected to one end of the roller brush 20. Simultaneously, two sets of sprockets 17 are installed inside the second power box 8, with a ratio of 1:2. The two sets of sprockets 17 are connected by a chain, and the smaller sprocket 17 is connected to the shaft at the end of the circulating filter cloth 13. Then, in the filter housing 4... A chip guide plate 19 is movably installed at the end. The chip guide plate 19 is located inside the movable cover plate 9 and below the circulating filter cloth 13. The chip guide plate 19 is inclined. An installation shell 12 is fixedly installed on the inner side of the filter box 4. Then, a filter canister 15 is fixedly installed inside the installation shell 12. At the same time, filter cotton 16 is filled inside the filter canister 15. A connecting pipe is fixedly installed at the bottom of the filter canister 15. The connecting pipe communicates with the inside of the water tank body 1 and can filter and collect the cleaned water.

[0033] Working principle: When this utility model is in use, the liquid containing impurities enters the interior of the filter box 4 and then flows to the surface of the circulating filter cloth 13. Subsequently, the centrifugal pump 5 is started, which creates an initial negative pressure inside the water tank body 1. Then, the liquid passes through the circulating filter cloth 13 and enters the lower part of the negative pressure chamber filter box 4. The impurities are isolated by the circulating filter cloth 13 and form a filter cake. Then, as the thickness of the filter cake increases, the reducer 14 drives the circulating filter cloth 13 to rotate, so that the circulating filter cloth 13 drives the filter cake to contact the roller brush 20, thereby cleaning the filter cake by the roller brush 20. Then, the chip guide plate 19 opens, allowing the filter residue to fall into the chip collection cart 3 for collection, which facilitates the cleaning of the filter residue.

[0034] Subsequently, the gas-liquid mixing pump 6 drives the liquid inside the water tank body 1 into the filter box 4 to come into contact with the circulating filter cloth 13, so that the circulating filter cloth 13 can better clean impurities when rotating. Then, the remaining liquid can enter the installation shell 12 and then be filtered by the filter cotton 16. After that, the filtered liquid enters the water tank body 1 through the pipe at the bottom of the filter tank 15 for return, so that the circulating filter cloth 13 can be used more effectively.
