Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment inverted membrane structure. Background Technology

[0002] In the process of sewage treatment, the open space above the sewage tank is sealed by combining special membrane materials with steel structures to prevent the unorganized emission of malodorous gases. This creates the conditions for subsequent biological deodorization or activated carbon adsorption of waste gases. Carbon steel or stainless steel supports are used to suspend the membrane material below, rather than covering the steel structure with the traditional membrane material. This avoids the steel components from directly contacting corrosive waste gases and greatly extends their service life.

[0003] Existing inverted membrane structures for wastewater treatment sealing suffer from problems, as mentioned in authorization announcement number CN223119218U "A High-Sealing and Corrosion-Resistant Inverted Membrane Structure," namely, the necessity of manual cleaning of the tank after a period of use. Furthermore, the integral nature of the inverted membrane structure makes it difficult to shrink or fold, hindering subsequent cleaning of the wastewater tank and ultimately leading to inconvenience and reduced practicality. Utility Model Content

[0004] This utility model addresses the problem of inconvenient folding and storage of inverted membrane structures, which also hinders subsequent cleaning of wastewater tanks. It provides a wastewater treatment inverted membrane structure that allows for easy folding and storage, thus improving usability.

[0005] To solve the above problems, the technical solution of this utility model is: A wastewater treatment inverted membrane structure includes a wastewater tank with its upper opening sealed by a membrane material. It also includes n-shaped frames and limiting components. The membrane material is fixedly connected to the n-shaped frames at intervals. Each n-shaped frame is slidably connected to the wastewater tank from the left and right sides. Limiting components are symmetrically arranged on the front and rear sides of the multiple n-shaped frames. The front limiting component includes a friction rod and a limiting assembly. Vertical poles are fixed to the front ends of the left and right outer sides of the wastewater tank. Two friction rods are connected between the opposing surfaces of two vertical poles. Both friction rods are located on the front sides of the multiple n-shaped frames. Each n-shaped frame has a limiting assembly located between two friction rods on its front side. The limiting assembly includes a connecting block and a friction block. The connecting block is fixedly connected to the front side of the corresponding n-shaped frame and slidably disposed within two friction rods. The connecting block has friction blocks for pressing against or moving away from the two friction rods.

[0006] Furthermore, I-beams are fixed to the upper ends of the front and rear side walls of the sewage tank. The web of the I-beams divides the space between the two flanges of the I-beams into two U-shaped grooves with opposite openings. Each n-shaped frame has an n-shaped groove recessed at its end. The n-shaped groove is locked onto the outside of the I-beam on the same side. Rollers are rotatably connected to the front and rear side walls of the n-shaped groove. Each roller extends into the U-shaped groove on the same side, and the lower end of each roller rolls in contact with the bottom surface of the U-shaped groove.

[0007] Furthermore, each corner of the connecting block is cut by a plane to form an inclined surface, and each connecting block is connected to a vertical plate on its left and right sides. Each inclined surface on the connecting block is provided with a friction block.

[0008] Furthermore, the two inclined surfaces on the upper side of the connecting block are symmetrical from left to right, and the two inclined surfaces on the left side of the connecting block are symmetrical from top to bottom; the two friction blocks on the upper side of the connecting block are symmetrical from left to right, and the two friction blocks on the left side of the connecting block are symmetrical from top to bottom.

[0009] Furthermore, the friction block is a right-angled triangular prism with a corresponding inclined surface on the inclined sliding connection block. The left straight surface of the upper left friction block faces the left vertical plate, and the upper straight surface faces the upper friction rod. The left straight surface of the friction block is connected to the left vertical plate via a spring. The upper part of the left vertical plate is threaded with a bolt whose free end contacts the left straight surface of the friction block. When the spring is in its natural state, there is a gap between the straight surface of the friction block facing the corresponding friction rod and the friction rod.

[0010] Furthermore, each inclined surface on the connecting block is fixedly connected with a limiting rod along its length direction. The limiting rod is an isosceles trapezoidal rod, and the width of the end of the limiting rod connected to the inclined surface is smaller than the width of the end of the limiting rod away from the inclined surface. The inclined surface of the friction block has a groove that slides and is locked outside the limiting rod.

[0011] The beneficial effects of this utility model through the above technical solution are as follows: In use, the membrane material is supported by multiple n-shaped frames to enclose the sewage tank. The n-shaped frames are limited by limiting components and friction rods. When the n-shaped frames are subjected to wind load and changes in pressure inside the tank, or when the n-shaped frames are subjected to forces to the left or right, the friction blocks on the limiting components can make the n-shaped frames more securely connected to the friction rods, thereby improving structural stability. After the limiting component of the n-shaped frame of this utility model is released from the connection with the friction rod, the n-shaped frame can move to the left or right, thereby storing the membrane material, making it easy to open the sewage tank and facilitate cleaning.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-5 As shown, a sewage treatment inverted membrane structure includes a sewage tank 1, which is a rectangular tank with an open top. The opening of the sewage tank 1 is sealed by a membrane material 2, which is a fluorocarbon fiber membrane. It also includes n-shaped frames 3 and limiting components. The n-shaped frames 3 are fixedly connected to the outside of the membrane material 2 from left to right at intervals. The ends of each n-shaped frame 3 are slidably connected to the sewage tank 1 to the left and right. Limiting components are symmetrically arranged on the front and rear sides of the multiple n-shaped frames 3. The front limiting component includes a friction rod 4 and a limiting assembly. Vertical poles 5 are fixed to the front ends of the left and right outer sides of the sewage tank 1. The upright 5 is a rectangular rod, and two friction rods 4 are connected between the opposite faces of two upright 5. There is a gap between the two friction rods 4. The friction rods 4 are rectangular rods, and both friction rods 4 are located on the front side of multiple n-shaped frames 3. Each n-shaped frame 3 has a limiting component located between two friction rods 4 on its front side. The limiting component includes a connecting block 6 and a friction block 7. The connecting block 6 is fixedly connected to the front side of the corresponding n-shaped frame 3. The connecting block 6 is slidably disposed in the two friction rods 4. The connecting block 6 is provided with friction blocks 7 for pressing against or moving away from the two friction rods 4.

[0015] I-beams 8 are fixed to the upper ends of the front and rear side walls of the sewage tank 1. The web of the I-beam 8 divides the two flanges of the I-beam 8 into two U-shaped grooves 9 with opposite openings. Each n-shaped frame 3 has an n-shaped groove 15 recessed at its end. The left, right and lower ends of the n-shaped groove 15 are open. The n-shaped groove 15 is locked outside the I-beam 8 on the same side. Rollers 10 are rotatably connected to the front and rear side walls of the n-shaped groove 15. Each roller 10 extends into the U-shaped groove 9 on the same side, and the lower end of each roller 10 rolls in contact with the bottom surface of the U-shaped groove 9. The ends of the two I-beams on the same side are connected by a connecting rod.

[0016] Each corner of the connecting block 6 is cut by a plane to form an inclined surface. Each connecting block 6 has a vertical plate 16 connected to its left and right sides. Each inclined surface on the connecting block 6 is provided with a friction block 7.

[0017] The two inclined surfaces on the upper side of the connecting block 6 are symmetrical from left to right, and the two inclined surfaces on the left side of the connecting block 6 are symmetrical from top to bottom; the two friction blocks 7 on the upper side of the connecting block 6 are symmetrical from left to right, and the two friction blocks 7 on the left side of the connecting block 6 are symmetrical from top to bottom.

[0018] The friction block 7 is a right-angled triangular prism on the inclined surface of the sliding connection block 6. The left straight surface of the upper left friction block 7 faces the left vertical plate 16, and the upper straight surface faces the upper friction rod 4. The left straight surface of the friction block 7 is connected to the left vertical plate 16 via a spring 11. The upper part of the left vertical plate 16 is threaded with a bolt 17 whose free end contacts the left straight surface of the friction block 7. When the spring 11 is in its natural state, there is a gap between the straight surface of the friction block 7 facing the corresponding friction rod 4 and the friction rod 4.

[0019] Each inclined surface of the connecting block 6 is fixedly connected with a limiting rod 12 along its length. The limiting rod 12 is an isosceles trapezoidal rod. The width of the end of the limiting rod 12 connected to the inclined surface is smaller than the width of the end of the limiting rod 12 away from the inclined surface. The inclined surface of the friction block 7 has a recessed groove 13 that slides and is locked outside the limiting rod 12. The groove 13 is an isosceles trapezoidal groove that corresponds to the limiting rod 12. A retaining plate 14 is fixed on the front side of the front connecting block 6. The upper and lower parts of the rear side of the retaining plate 14 slide in contact with the front sides of the two front friction rods 4 respectively.

[0020] The friction block 7 is a block made of metal and fiber-reinforced materials, and the friction rod 4 is a rod made of metal and fiber-reinforced materials.

[0021] Working principle: When the membrane material 2 of this utility model is fully unfolded, it closes the upper opening of the sewage tank 1. At this time, the free end of the bolt 17 on each limiting component presses against the straight surface of the corresponding friction block 7. During the process of the free end of the bolt 17 pressing against the corresponding friction block 7, the friction block 7 moves along the length direction of the inclined plane. When the friction block 7 moves along the corresponding inclined plane, the other straight surface of the friction block 7 presses against the corresponding friction rod 4. The spring 11 connected to the friction block 7 is in a stretched state, and the connecting block 6 and the connected n-shaped frame 3 are limited and fixed. Moreover, when the wind load or the pressure in the tank changes, the n-shaped frame 3 will be subjected to a force to the left or right. When the n-shaped frame 3 is subjected to a force to the left, the n-shaped frame 3 will drive the connecting block 6 to tend to move to the left. The two inclined surfaces on the left side of the connecting block 6 exert a force to the left on the inclined surface of the corresponding friction block 7. This leftward force will drive the friction block 7 to produce a slight sliding along the inclined surface of the connecting block 6. The sliding tendency of friction block 7, being a right-angled triangular prism and slidably connected to connecting block 6 via an inclined surface, decomposes the leftward force into two components: one along the inclined surface and the other a pressure component perpendicular to the surface of friction rod 4. The pressure component perpendicular to friction rod 4 directly increases the normal force between the surface of friction block 7 and friction rod 4, and the increase in normal force simultaneously enhances the static friction between the two. Therefore, the two symmetrical friction blocks 7 on the left side form a bidirectional pressing effect, applying greater compressive force to the friction rod 4 on the same side from both the top and bottom, effectively counteracting the leftward movement tendency of n-shaped frame 3, making the connection between n-shaped frame 3 and friction rod 4 via the limiting component more secure, and ensuring structural stability. Similarly, when n-shaped frame 3 is subjected to a rightward force, the friction block 7 on the limiting component can also counteract the rightward movement tendency of n-shaped frame 3, making the connection between n-shaped frame 3 and friction rod 4 via the limiting component more secure. When cleaning the sewage tank 1 is required, the free end of each bolt 17 on the n-shaped frame 3 is released from its pressure on the corresponding friction block 7, so that the spring 11 connected to each friction block 7 is in its natural state. At this time, under the action of the spring 11, each friction block 7 moves away from the friction rod 4 on the same side. At this time, the limiting component on the n-shaped frame 3 is released from its limitation on the friction rod 4, and each n-shaped frame 3 can be pushed to the right along the length direction of the I-beam 8. The n-shaped frame 3 drives the membrane material 2 to be folded and stored. The roller 10 on the n-shaped frame 3 helps the n-shaped frame 3 to move. After the membrane material 2 is folded and stored, the upper opening of the sewage tank 1 is opened, and the sewage tank 1 can be cleaned. Moreover, the n-shaped frame 3 of this utility model can move one or more n-shaped frames 3 according to the size of the upper opening that needs to be opened in the sewage tank 1, and is not limited to the position of the n-shaped frame 3 along the friction rod 4. After the movement, the n-shaped frame 3 can be reconnected to the friction rod 4 through the limiting component to ensure that the size of the sewage tank opening remains unchanged. After cleaning, each n-shaped frame 3 returns to its initial position, the limiting components on the n-shaped frame 3 re-fix the limiting components with the friction rod 4, and the membrane material 2 unfolds to close the upper opening of the sewage tank 1.

However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
