Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to a device for efficient scraping and protecting filter cloth. Background Technology

[0002] The device for efficient scraping and protecting the filter cloth is a key component in filtration equipment. Its main purpose is to remove residual material from the surface of the filter cloth while minimizing wear and damage to the filter cloth. The design and function of this device can improve filtration efficiency, extend the life of the filter cloth, and reduce maintenance costs.

[0003] During the use of the filtration equipment, the material to be filtered is first laid on the filter cloth. Then, as the filter cloth moves, the external vacuum pump generates negative pressure, which allows the liquid to pass through the filter cloth. Solid particles are then trapped on the surface of the filter cloth. When the filter cloth passes through the scraper device, the scraper device will scrape off the solid particles on the surface of the filter cloth.

[0004] In existing scraper devices, the scraper is in direct contact with the filter cloth and adheres tightly to the filter cloth under external force. The filter cloth joint is made with glue and has protrusions. When the joint passes through the scraper, it is subjected to a lot of external force, which can easily scrape off the glue and damage the joint. Therefore, we propose a device for efficient scraping and protecting the filter cloth. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a device for efficient scraping and protecting filter cloth. By cooperating with the scraper and roller, the position of the scraper can be adjusted by the roller. When the filter cloth joint passes through the scraper and roller, the pressure of the scraper on the filter cloth joint is reduced, which solves the problem of the filter cloth joint being damaged by the scraper scraping off the glue, thereby protecting the filter cloth joint and further improving the integrity of the filter cloth joint. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for efficient scraping and protecting filter cloth, comprising a frame;

[0007] Frame: The front end of the frame is equipped with filter cloth, and the right end of the frame is equipped with a scraper and a roller. The scraper is located below the roller, and the left end of the scraper and the outer arc surface of the roller are in contact with the outer surface of the filter cloth. Through the cooperation of the scraper and the roller, the position of the scraper can be adjusted by the roller. When the filter cloth joint passes through the scraper and the roller, the pressure of the scraper on the filter cloth joint is reduced, which solves the problem of the filter cloth joint being damaged by the scraper scraping off the glue, thereby protecting the filter cloth joint and further improving the integrity of the filter cloth joint.

[0008] Furthermore, it includes a discharge roller, which is rotatably connected to the front end of the bearing seat. The outer arc surface of the discharge roller is in contact with the inner surface of the filter cloth. The main function of the discharge roller is to support and carry the filter cloth, ensuring that the filter cloth will not sag or deform during the conveying process.

[0009] Furthermore, a scraper bracket is placed on the right side of the frame, and a scraper is provided at the right end of the scraper bracket. The scraper bracket can adjust the position of the scraper to reduce the external force of the scraper on the filter cloth joint, thereby protecting the filter cloth joint.

[0010] Furthermore, a roller bracket one is provided in the middle of the right end of the scraper bracket, the scraper is located inside the bracket one, a roller bracket two is provided on the right side inside the roller bracket one, and a roller is rotatably connected to the left side inside the roller bracket two, so that the roller bracket one can be moved by the roller bracket two, and the roller bracket one will drive the scraper bracket to move.

[0011] Furthermore, there is an adjustment groove in the middle of the left end of the roller bracket two, and the roller is located inside the adjustment groove, which allows the position of the roller to be adjusted.

[0012] Furthermore, the longitudinal line where the contact points between the roller and the filter cloth converge and the longitudinal line where the contact points between the scraper and the filter cloth converge are parallel and on the same plane, which makes the filter cloth more uniformly stressed on the plane.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-efficiency material scraping and filter cloth protection device has the following advantages:

[0014] By using a combination of a scraper and rollers, the position of the scraper can be adjusted via the rollers. When the filter cloth joint passes the scraper and rollers, the pressure of the scraper on the filter cloth joint is reduced, solving the problem of the filter cloth joint being damaged by the scraper scraping off the adhesive. This protects the filter cloth joint and further improves its integrity. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2 This embodiment provides a technical solution: a device for efficient scraping and protecting filter cloth, including a frame 1;

[0020] Frame 1: The front end of the frame 1 is equipped with filter cloth 2, and the right end of the frame 1 is equipped with a scraper 5 and a roller 8. The scraper 5 is located below the roller 8. The left end of the scraper 5 and the outer arc surface of the roller 8 are in contact with the outer surface of the filter cloth 2. Through the cooperation of the scraper 5 and the roller 8, the position of the scraper 5 can be adjusted by the roller 8. When the filter cloth 2 joint passes through the scraper 5 and the roller 8, the pressure of the scraper 5 on the filter cloth 2 joint is reduced, which solves the problem of the filter cloth 2 joint being damaged by the scraper 5 scraping off the glue, thereby protecting the joint of the filter cloth 2 and further improving the integrity of the filter cloth 2 joint.

[0021] The system includes a discharge roller 3, which is rotatably connected to the front end of the bearing seat. The outer arc surface of the discharge roller 3 is in contact with the inner surface of the filter cloth 2. The filter cloth 2 is in contact with the outer arc surface of the upper discharge roller 3, and then the filter cloth 2 is in contact with the outer arc surface of the lower discharge roller 3. Finally, the filter cloth 2 is wound around the external winding device. The main function of the discharge roller 3 is to support and carry the filter cloth 2, ensuring that the filter cloth 2 will not sag or deform during the conveying process.

[0022] Among them: a scraper bracket 4 is placed on the right side of the frame 1, and a scraper 5 is provided at the right end of the scraper bracket 4. The scraper bracket 4 can adjust the position of the scraper 5, reduce the external force of the scraper 5 on the joint of the filter cloth 2, and thus protect the joint of the filter cloth 2.

[0023] Among them, the scraper bracket 4 is made of rigid material and will not bend. The material used for the scraper bracket 4 is carbon steel, which has high strength and good mechanical properties.

[0024] Specifically: a roller bracket 1 6 is provided in the middle of the right end of the scraper bracket 4, and the scraper 5 is located inside the bracket 1 6. A roller bracket 2 7 is provided on the right side inside the roller bracket 1 6. A roller 8 is rotatably connected to the left side inside the roller bracket 2 7. When the roller 8 is raised, the roller 8 will drive the roller bracket 1 6 to move to the right through the roller bracket 2 7. The roller bracket 1 6 will then drive the scraper to move to the right through the scraper bracket 4, thereby driving the scraper 5 to be raised accordingly.

[0025] Among them, the roller bracket 2 has an adjustment groove in the middle of the left end. The roller 8 is located inside the adjustment groove. When the scraper 5 is worn and needs to be replaced, the operator rotates the locking nut to loosen the adjusting bearing seat. The roller 8 is rotatably connected between the two adjusting bearing seats. Then the operator pushes the front adjusting bearing seat to drive the roller 8 to move to the right along the adjustment groove, thus leaving enough space for replacing the scraper 5. When the roller 8 moves to the designated position, the operator retightens the locking nut.

[0026] Wherein: the longitudinal line where the contact point between the roller 8 and the filter cloth 8 converges and the longitudinal line where the contact point between the scraper 5 and the filter cloth 2 converges are parallel and on the same plane. When the longitudinal line where the contact point between the roller 8 and the filter cloth 8 converges and the longitudinal line where the contact point between the scraper 5 and the filter cloth 2 converges are parallel and on the same plane, the force on the filter cloth 2 on this plane mainly comes from the pressure of the scraper 5 and the supporting force of the roller 8. Since these two forces are on the same horizontal line, they can form a relatively balanced force system, making the force on the filter cloth 2 on this plane more uniform.

[0027] The working principle of the high-efficiency scraping and filter cloth protection device provided by this utility model is as follows: During the use of the high-efficiency scraping and filter cloth protection device, the filter cloth 2 is first brought into contact with the outer arc surface of the upper unloading roller 3, and then the filter cloth 2 is brought into contact with the outer arc surface of the lower unloading roller 3. When the joint of the filter cloth 2 passes the roller 8, the roller 8 will be raised to the right along with the protrusion at the joint of the filter cloth 2. Since the roller 8 and the scraper 5 are fixed on the same scraper bracket 4, when the roller 8 is raised, the roller 8 will drive the roller bracket 6 to move to the right through the roller bracket 7. The roller bracket 6 will then drive the scraper to move to the right through the scraper bracket 4, thereby driving the scraper 5 to be raised to the right accordingly. At this time, the external force of the scraper 5 on the joint of the filter cloth 2 is greatly reduced, thus protecting the joint of the filter cloth 2. The scraper bracket 4 is connected to the corresponding fixed base through the bolt connection. When the scraper bracket 4 moves to the right, the external elastic component will always pass through the fixed base. A leftward push is applied to the scraper bracket 4, ensuring that the scraper 5 and roller 8 remain in contact with the outer arc surface of the filter cloth 2. The scraper 5 then scrapes away any adhering objects from the outer surface of the filter cloth 2. After scraping, the filter cloth 2 is wound onto an external winding device. When the scraper 5 needs replacement due to wear, the operator rotates the locking nut to loosen the adjusting bearing seat. The roller 8 is rotatably connected between the two adjusting bearing seats. The operator then pushes the front adjusting bearing seat to move the roller 8 along the adjusting groove to the right, providing sufficient space for scraper 5 replacement. When the roller 8 reaches the designated position, the operator retightens the locking nut to lock and fix the roller 8. Finally, the scraper 5 is replaced. (The scraper 5 is replaced using the common technique used in the disassembly and replacement of scrapers and scraper brackets in existing technologies.) The scraper bracket 4 is made of carbon steel, which has high strength and good mechanical properties.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
