Description

Technical Field

[0001] This utility model belongs to the field of industrial waste liquid filtration technology, specifically an industrial waste liquid membrane filtration device. Background Technology

[0002] Membrane filtration equipment utilizes selectively permeable membranes. Under the influence of pressure or concentration differences, certain substances are allowed to pass through while others are blocked, thus achieving separation, concentration, and purification. After prolonged use, the internal membrane filter element of a membrane filtration equipment can easily reach saturation, resulting in a significant decrease in filtration flux (the amount of liquid permeating per unit membrane area per unit time), leading to low filtration efficiency. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an industrial waste liquid membrane filtration device, which solves the problem that after long-term use, the internal membrane filter element of the membrane filtration device is prone to saturation, resulting in a significant decrease in filtration flux and thus low filtration efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an industrial waste liquid membrane filtration device, comprising a base plate, a plurality of cylinders fixedly connected to the top of the base plate, threaded grooves being provided on the cylinders, an internal threaded ring being fitted on the cylinders, the internal threaded ring being threadedly connected to the threaded grooves, four L-shaped plates being fixedly connected to the top of the internal threaded rings, and a connector being provided at the top of the cylinders, the connector having a first annular groove.

[0005] The L-shaped plate is located inside the first annular groove. The connector has four clearance grooves. The bottom of the connector is fixedly connected to a first limiting cover. The inside of the cylinder is fixedly connected to a second limiting cover. The second limiting cover is provided with a membrane filter element. The membrane filter element is located inside the first limiting cover. The top of the connector is fixedly connected to a hose.

[0006] As a further embodiment of this utility model: two upright plates are fixedly connected to the top of the base plate, and water inlet pipes and water outlet pipes are fixedly connected to the two upright plates.

[0007] As a further embodiment of this utility model: several rigid pipes are fixedly connected to the water inlet pipe, and the rigid pipes are fixed to the flexible pipe.

[0008] As a further embodiment of this utility model: a plurality of conveying pipes are fixedly connected to the water outlet pipe, and the conveying pipes are fixed to the cylinder body.

[0009] As a further embodiment of this utility model: the inlet pipe, rigid pipe, flexible pipe, connector, cylinder, delivery pipe and outlet pipe are connected in communication, and a number of handles are fixedly connected to the internal threaded ring, and the number of handles are evenly distributed on the internal threaded ring.

[0010] As a further embodiment of this utility model: two second annular grooves are provided on the first limiting cover, and a rubber sealing ring is provided inside the second annular groove.

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

[0012] This industrial waste liquid membrane filtration equipment, through the configuration of a connector, a first annular groove, a clearance groove, a first limiting cover, a second limiting cover, an L-shaped plate, a threaded groove, and an internal threaded ring, allows for disassembly of the membrane filter element. Turning the handle rotates the internal threaded ring, which, being threaded onto the threaded groove, moves upwards. This upward movement of the internal threaded ring drives the L-shaped plate upwards, while the L-shaped plate also rotates within the first annular groove. The L-shaped plate lifts the connector, causing it and the first limiting cover to move upwards until the first limiting cover is completely detached from the cylinder. At this point, rotating the connector aligns the clearance groove with the L-shaped plate, and the L-shaped plate is then passed through the clearance groove. This allows the connector to be separated from the L-shaped plate, preventing the connector from obstructing the membrane filter element and enabling its removal. When installing the membrane filter element, first place it inside the second limiting cover. Pass the L-shaped plate through the clearance groove and place it inside the first annular groove. Place the first limiting cover on the membrane filter element and rotate the handle in the opposite direction to rotate the internal threaded ring. This causes the internal threaded ring, the L-shaped plate, and the connector to move downwards, using the connector to obstruct the membrane filter element and complete the installation. This equipment facilitates the disassembly and installation of the membrane filter element. When the membrane filter element reaches filtration saturation, it can be quickly disassembled for cleaning or replacement, preventing problems such as decreased filtration flux and low filtration efficiency.

[0013] This industrial waste liquid membrane filtration equipment, by setting a first limiting cover and a rubber sealing ring, when the membrane filter element needs to be installed, first place the membrane filter element inside the second limiting cover, pass the L-shaped plate through the clearance groove and place the L-shaped plate inside the first annular groove, put the first limiting cover on the membrane filter element, and rotate the handle in the opposite direction to drive the internal thread ring to rotate. When the first limiting cover is put on the membrane filter element, since the outer diameter of the rubber sealing ring is slightly larger than the inner diameter of the cylinder, the rubber sealing ring will be squeezed by the cylinder, and the rubber sealing ring will seal the cylinder, thereby effectively improving the sealing performance of the cylinder.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figure 1-5 As shown, this utility model provides a technical solution: an industrial waste liquid membrane filtration device, including a base plate 1, a plurality of cylinders 2 fixedly connected to the top of the base plate 1, threaded grooves 10 opened on the cylinders 2, and internal threaded rings 11 fitted on the cylinders 2, the internal threaded rings 11 being threadedly connected to the threaded grooves 10, two vertical plates 3 fixedly connected to the top of the base plate 1, water inlet pipes 4 fixedly connected to the two vertical plates 3, and water outlet pipes 5 fixedly connected to the two vertical plates 3.

[0022] Four L-shaped plates 13 are fixedly connected to the top of the internal threaded ring 11. A connector 9 is provided on the top of the cylinder 2. A first annular groove 17 is provided on the connector 9. The L-shaped plates 13 are located inside the first annular groove 17. Four clearance grooves 18 are provided on the connector 9. Because of the clearance grooves 18, the L-shaped plates 13 can pass through the clearance grooves 18 to facilitate the separation of the connector 9 from the L-shaped plates 13, so that the connector 9 no longer blocks the membrane filter element 16, thus making it easy to remove the membrane filter element 16. Several rigid pipes 6 are fixedly connected to the water inlet pipe 4. The rigid pipes 6 are fixed to the flexible hose 8.

[0023] The bottom of the connector 9 is fixedly connected to a first limiting cover 14. Because of the first limiting cover 14 and the second limiting cover 15, the membrane filter element 16 is placed inside the second limiting cover 15 and the first limiting cover 14 for limiting, which can prevent the membrane filter element 16 from shaking and improve the stability of the membrane filter element 16. The first limiting cover 14 has two second annular grooves 19. The second annular grooves 19 are provided with rubber sealing rings 20. Because of the rubber sealing rings 20, when the first limiting cover 14 is put on the membrane filter element 16, the outer diameter of the rubber sealing ring 20 is slightly larger than the inner diameter of the cylinder 2. Therefore, the rubber sealing ring 20 will be squeezed by the cylinder 2 and seal the cylinder 2, thereby effectively improving the sealing performance of the cylinder 2. The second limiting cover 15 is fixedly connected inside the cylinder 2. The membrane filter element 16 is provided inside the second limiting cover 15. The membrane filter element 16 is located inside the first limiting cover 14.

[0024] A flexible hose 8 is fixedly connected to the top of the connector 9. Several delivery pipes 7 are fixedly connected to the water outlet pipe 5. The delivery pipes 7 are fixed to the cylinder 2. The water inlet pipe 4, rigid pipe 6, flexible hose 8, connector 9, cylinder 2, delivery pipes 7 and water outlet pipe 5 are connected. Several handles 12 are fixedly connected to the internal threaded ring 11. Because of the handles 12, the handles 12 provide gripping points, making it easy for personnel to grip the handles 12 to rotate the internal threaded ring 11, improving the ease of operation. Several handles 12 are evenly distributed on the internal threaded ring 11.

[0025] The working principle of this utility model is as follows:

[0026] Industrial waste liquid enters through inlet pipe 4, passes through rigid pipe 6, flexible pipe 8, and connector 9 into the cylinder 2, and after being filtered by membrane filter element 16, enters the conveying pipe 7 and is finally discharged from outlet pipe 5, thus achieving the filtration of industrial waste liquid. When it is necessary to disassemble membrane filter element 16, turn handle 12 to drive internal threaded ring 11 to rotate. Since internal threaded ring 11 is threaded onto threaded groove 10, it can move upward when rotating. Internal threaded ring 11 will drive L-shaped plate 13 to move upward, and L-shaped plate 13 will also rotate inside the first annular groove 17 while moving upward. L-shaped plate 13 lifts connector 9, causing connector 9 and first limiting cover 14 to move upward until the first limiting cover 14 is completely disengaged. Inside the cylinder 2, rotating the connector 9 aligns the clearance groove 18 with the L-shaped plate 13, and passing the L-shaped plate 13 through the clearance groove 18 separates the connector 9 from the L-shaped plate 13, so that the connector 9 no longer obstructs the membrane filter element 16, allowing the membrane filter element 16 to be disassembled. When it is necessary to install the membrane filter element 16, first place the membrane filter element 16 inside the second limiting cover 15, pass the L-shaped plate 13 through the clearance groove 18 and place the L-shaped plate 13 inside the first annular groove 17, put the first limiting cover 14 on the membrane filter element 16, and rotate the handle 12 in the opposite direction to drive the internal threaded ring 11 to rotate, causing the internal threaded ring 11, the L-shaped plate 13 and the connector 9 to move down, using the connector 9 to block the membrane filter element 16, thereby completing the installation of the membrane filter element 16.
