Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment, and in particular to a quick-installation membrane frame. Background Technology

[0002] In wastewater treatment, ultrafiltration membrane modules typically rely on a frame structure to achieve the positioning, water supply, and aeration functions of the membrane curtain. Traditional frames have three major drawbacks: First, fixed height makes adaptation difficult: existing frames mostly use welded or bolted structures, which cannot accommodate membrane curtains of different heights. Replacing the membrane curtain requires replacing the entire frame, increasing costs. Second, low installation efficiency: connecting water pipes to the membrane curtain requires aligning each positioning hole individually, along with elbows, sealing rings, and other components, making installation of a single membrane curtain time-consuming. Third, insufficient structural stability: the membrane curtain relies solely on longitudinal reinforcing ribs for support. Over long-term use, the membrane curtain sags and deforms due to increased weight from adsorbed impurities, and the lack of lateral support exacerbates the risk of pipeline sealing failure.

[0003] Existing technologies propose adjustable mold frames, but these rely on threaded rods for height adjustment, requiring bolt removal during the adjustment process, which is complex and difficult to lock precisely. While an ultrafiltration device is proposed in patent document CN202010061674.8, entitled "A Curtain Membrane Module for Water Purification," which addresses structural stability, other issues remain. Therefore, there is an urgent need for a mold frame solution that supports rapid installation, flexible height adjustment, and a robust structure. Utility Model Content

[0004] The purpose of this invention is to provide a quick-installation film frame to address the problems of high fixation difficulty in adaptation, low installation efficiency, and insufficient structural stability in existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-installation membrane frame, comprising four membrane curtain positioning components symmetrically arranged at the top and bottom and front and back, and four longitudinal reinforcing ribs symmetrically fixed on the left and right sides of the two membrane curtain positioning components at the top and bottom ends. The membrane curtain positioning component is a rectangular plate with a number of U-shaped through holes evenly distributed on its upper surface.

[0006] Preferably, a water pipe is connected to the two U-shaped through holes on the front and rear sides, and the two water pipes on the same plane on the front and rear sides are connected to a membrane curtain.

[0007] Preferably, the middle part of the membrane curtain is an ultrafiltration membrane, and the upper and lower ends of the ultrafiltration membrane are symmetrically connected and connected to two pipes. The left and right ends of each pipe are connected to two corresponding water pipes.

[0008] Preferably, two upper sleeves are symmetrically fixed on the lower surfaces of the left and right ends of the upper membrane curtain positioning component, and two lower sliding rods are symmetrically fixed on the upper surfaces of the left and right ends of the lower membrane curtain positioning component. The upper sleeves and lower sliding rods are matched and form an up-and-down sliding structure.

[0009] Preferably, the upper sleeve has several adjustment through holes evenly distributed along its axial direction, and the lower slide rod has several identical adjustment through holes evenly distributed along its axial direction.

[0010] Preferably, an L-shaped clamp is bolted to the outside of the U-shaped through hole of the membrane curtain positioning component. The L-shaped clamp has an arc segment that matches the arc segment of the U-shaped through hole, and the arc segments of both clamp together hold the water pipe.

[0011] Preferably, the bottom of the upper and lower pipes of the membrane curtain is symmetrically provided with two transverse reinforcing ribs, and the two transverse reinforcing ribs are simultaneously and vertically fixed to the two longitudinal reinforcing ribs at the same end of the upper and lower ends.

[0012] Preferably, it also includes several aeration pipe supports that are longitudinally fixed to the bottom of the two lower membrane curtain positioning members. The aeration pipe supports are U-shaped, and their upper surfaces are fixed to the lower surfaces of the membrane curtain positioning members.

[0013] Compared with the prior art, the present invention provides a graphite pressing molding mold opening device, which has the following beneficial effects.

[0014] 1. Flexible height adjustment: The positioning components of the membrane curtain adopt a sliding connection between the upper sleeve and the lower slide rod. With the axially evenly distributed adjustment through holes and pins, the overall height of the mold frame can be adjusted within a certain range. The operation is simple and quick, and the locking is firm. It effectively solves the compatibility problem of membrane curtains of different heights and enhances the versatility and adaptability of the equipment.

[0015] 2. Rapid installation and high integration: The standardized quick-installation membrane frame body, consisting of four membrane curtain positioning components and four longitudinal reinforcing ribs, combined with special U-shaped through holes and L-shaped clamps, enables rapid and accurate positioning and reliable connection of the membrane curtain and water pipes, significantly simplifying on-site installation steps and improving assembly efficiency.

[0016] 3. Enhanced structural stability: The transverse reinforcing ribs are vertically fixed to the longitudinal reinforcing ribs, improving the bending strength of the membrane curtain; the L-shaped clamps and U-shaped through holes are connected by a double arc structure, improving the pressure-bearing capacity of the water pipes.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-6 A quick-installation membrane frame includes four membrane curtain positioning components 1 symmetrically arranged at the top and bottom and front and back, and four longitudinal reinforcing ribs 105 symmetrically fixed on the left and right sides of the two membrane curtain positioning components 1 at the top and bottom. The longitudinal reinforcing ribs 105 are used to connect the two membrane curtain positioning components 1 to ensure structural strength and stability. The membrane curtain positioning component 1 is a rectangular plate with several U-shaped through holes evenly distributed on its upper surface.

[0028] The two U-shaped through holes on the front and back sides are connected to a water pipe 3. The two water pipes 3 on the same plane on the front and back sides are connected to a membrane curtain 2. The membrane curtain 2 has an ultrafiltration membrane in the middle, with its upper and lower ends symmetrically connected to two pipes. The left and right ends of each pipe are connected to two corresponding water pipes 3. The membrane curtain 2 is used to treat raw water, i.e., dirty water containing pollutants, converting it into clean water. Several sets of membrane curtains 2 provide a large effective working area, and the membrane curtain 2 and water pipes 3 form a complete passage. To ensure the structure's airtightness and reasonable placement, elbows (such as right-angle elbows, tee elbows, etc.) can be used for connection. Using an ultrafiltration membrane as the filtration medium, under certain pressure, when raw water flows through the membrane surface, the numerous tiny micropores densely distributed on the membrane surface only allow water and small molecules to pass through, becoming the permeate. Substances in the raw solution with a volume larger than the micropore size are retained on the feed side of the membrane, becoming the concentrate, i.e., purified water. This achieves the purification, separation, and concentration of the raw water. The purified water flows along the ultrafiltration membrane into the pipes above and below it, then along water pipe 3 into a water storage device for storage, and is discharged when needed. Figure 7 As shown.

[0029] Two upper sleeves 101 are symmetrically fixed to the lower surfaces of the left and right ends of the upper membrane curtain positioning component 1, and two lower sliding rods 102 are symmetrically fixed to the upper surfaces of the left and right ends of the lower membrane curtain positioning component 1. The upper sleeves 101 and the lower sliding rods 102 are matched and form an up-and-down sliding structure. The upper sleeves 101 have several adjustment through holes evenly distributed along their axial direction, and the lower sliding rods 102 have several identical adjustment through holes evenly distributed along their axial direction. Because the height of the membrane curtain 2 is not fixed, the most common heights on the market are 1.5m and 1.8m. Different heights of the membrane curtain 2 require the installation mold frame to have a certain degree of adaptability adjustment capability. In this utility model, the lower sliding rods 102 are inserted into the upper sleeves 101 to form an up-and-down sliding structure. After adjusting to the appropriate height of the membrane curtain, a pin is inserted into the adjustment through hole between the two to lock the height. The height adjustment structure of this utility model can not only be adjusted quickly and is easy to operate, but also can adapt to membrane curtains 2 of different heights. Its processing, manufacturing, and installation are also simple and convenient, and the cost is low.

[0030] An L-shaped clamp 106 is bolted to the outside of the U-shaped through hole of the membrane curtain positioning component 1. The L-shaped clamp 106 has an arc segment that matches the arc segment of the U-shaped through hole, and the arc segments of both clamps together hold the water pipe 3 in place. Two transverse reinforcing ribs 104 are symmetrically arranged at the bottom of the upper and lower pipes of the membrane curtain 2. These two transverse reinforcing ribs 104 are simultaneously and vertically fixed to two longitudinal reinforcing ribs 105 at the same end of the upper and lower sections. Because the membrane curtain 2 has a certain weight, and this weight increases during operation due to the adsorption of impurities and water, the U-shaped through hole and the L-shaped clamp 106 work together to ensure that the water pipe is not bent or deformed at this point during operation. The transverse reinforcing ribs 104 support the membrane curtain 2 to prevent bending and deformation, but care must be taken during installation to avoid interfering with other components.

[0031] It also includes several aeration pipe supports 4 that are longitudinally fixed to the bottom of the two lower membrane curtain positioning members 1. The aeration pipe supports 4 are U-shaped, and their upper surfaces are fixed to the lower surfaces of the membrane curtain positioning members 1. The aeration pipe supports 4 are used for two purposes: first, to install other structures, and second, to connect the two lower membrane curtain positioning members 1, support the entire device, and ensure its structural strength.

[0032] Working process: After connecting all the components or structures of this utility model, welding or other connection methods can be used as needed. According to the actual height of the membrane curtain 2, insert the sliding rod 102 of this utility model into the upper sleeve 101 and adjust it to the appropriate height of the membrane curtain. Align the adjustment through hole between the two and insert the pin to lock the height. At the same time, ensure that the connection between the membrane curtain 2, water pipe 3 and water collection pipe is intact. When installing the L-shaped clamp 106 and the transverse reinforcing rib 104, be careful not to interfere with other components. The raw water uses the ultrafiltration membrane as the filter medium. Under a certain pressure, when the raw water flows through the membrane surface, the many tiny micropores on the surface of the ultrafiltration membrane only allow water and small molecules to pass through and become the permeate. Substances in the raw water with a volume larger than the micropore diameter of the membrane surface are trapped on the inlet side of the membrane and become the concentrate, i.e., purified water. Thus, the purpose of purifying, separating and concentrating the raw water is achieved. The purified water enters the pipes above and below the ultrafiltration membrane, and then enters the water storage equipment along the water pipe 3 for storage and discharge when needed.
