Description

Technical Field

[0001] This utility model relates to the field of paper production technology, specifically to an iron removal device for wood pulp. Background Technology

[0002] Impurities in wet pulp mainly include packaging plastic film, stones, and metal impurities. Among them, metal impurities have complex sources, high density, strong concealment, and are not easy to detect. Metals are also hard and can cause significant damage to equipment, shortening its lifespan. In severe cases, they may cause equipment damage, resulting in unexpected downtime and loss of production capacity.

[0003] A utility model patent with authorization announcement number CN 221085957 U discloses an iron removal device for a wet pulp line of household paper, including a conveying mechanism. The conveying mechanism is connected to a transmission structure via two belt drive structures. The transmission structure is mounted on two fixed frames, which are fixedly connected to the conveying mechanism. A connecting block is fixedly connected between the two fixed frames, and a magnetic plate is fixedly connected between the two connecting blocks. The magnetic plate overlaps with the transmission structure. This iron removal device for a wet pulp line of household paper, by setting up a belt drive structure, a transmission structure, and a magnetic plate, allows the conveying mechanism to drive the belt drive structure to move, enabling the magnetic roller and magnetic plate to adsorb iron impurities in the wet pulp conveyed on the conveying mechanism, causing them to adhere to the conveyor belt. This effectively separates the iron impurities. Furthermore, the magnetism at the roller position is eliminated, making it easy for the iron impurities to fall off directly, and preventing wear.

[0004] However, this device still has certain shortcomings in practical applications. While it uses a brush structure to prevent wear, the brushes on the brush plate are prone to damage during long-term cleaning. Because the brushes lack a disassembly and assembly structure, damaged brushes are difficult to replace or repair in a timely manner, leading to a gradual decrease in iron removal efficiency and affecting the long-term stable operation of the iron removal device. Utility Model Content

[0005] In view of this, the present invention provides an iron removal device for wood pulp. With the design of a detachable brush, the brush can be disassembled and replaced in time when it is damaged, thereby avoiding the impact on the iron removal effect and ensuring the long-term stable operation of the equipment.

[0006] To solve the above-mentioned technical problems, this utility model provides an iron removal device for wood pulp, including a fixed frame and a brush plate. A conveyor belt is connected to the fixed frame via a conveyor roller, and a magnetic roller is installed at the center of the fixed frame. A fixed block is provided at the end of the fixed frame, and a slot is opened at the end of the fixed block. The two ends of the brush plate are fixed with locking blocks, which are engaged in the locking slots. A brush is provided on one side wall of the brush plate, and the brush is in close contact with the surface of the conveyor belt. A locking mechanism is provided above the fixed block to limit and fix the locking blocks in the slot. When installing the brush plate, the operator inserts the fixed blocks at both ends of the brush plate into the slot, and then uses the locking mechanism to limit and fix the locking blocks in the slot, thereby completing the fixing of the brush plate. When it is necessary to disassemble the brush plate, the locking mechanism is used to release the locking of the locking blocks, so that the locking blocks can be pulled out of the slot, thereby completing the disassembly and assembly of the brush plate. This allows for timely disassembly and replacement when the brush is damaged, thus avoiding the impact on the iron removal effect and ensuring the long-term stable operation of the equipment.

[0007] The locking mechanism includes a through hole on the upper surface of the fixed block, a positioning pin inserted into the through hole, a positioning hole on the upper surface of the locking block, the lower end of the positioning pin inserted into the positioning hole, and a movable block on the upper end of the positioning pin. By pulling the movable block, the positioning pin can be disengaged or inserted into the positioning hole.

[0008] When the brush plate needs to be disassembled, pull the movable block upwards to move the positioning post upwards, causing the positioning post to disengage from the positioning hole, thereby removing the restriction on the sliding direction of the card block. Then, the card block can be pulled out of the slot. When installation is required, insert the card block into the slot, and then press the movable block. The movable block moves the positioning post downwards, causing the positioning post to insert into the positioning hole, thereby limiting and fixing the card block.

[0009] Springs are provided on both sides of the lower surface of the movable block. The upper end of the spring is fixed to the lower wall of the movable block, and the lower end of the spring is fixed to the upper surface of the fixed block. Through the design of the compression spring, when the positioning pin is inserted into the positioning hole, the compression spring can improve the stability of the positioning pin in the positioning hole and prevent the positioning pin from moving upward.

[0010] The movable block has through holes on both sides, through which guide rods are installed. The lower end of the guide rod passes through the center of the spring and is fixed to the upper wall of the fixed block. When the movable block is pulled, it moves vertically along the height of the guide rod, thereby improving the stability of the movement of the movable block and the positioning column.

[0011] A limit block is provided at the upper end of the guide rod. The cross-sectional area of ​​the limit block is larger than the cross-sectional area of ​​the through hole of the movable block. The limit block is designed to limit the stroke of the movable block, thereby preventing the positioning pin from moving too far and dislodging from the through hole of the fixed block.

[0012] The side of the positioning post facing the slot opening is beveled. When the brush plate needs to be installed, the locking block is aligned with the slot opening and inserted, so that the locking block contacts the beveled side of the positioning post and pushes the positioning post upward. At this time, the positioning post drives the movable block to move upward synchronously, so that the movable block stretches the compression spring. When the locking block is fully pushed into the slot, the lower end of the positioning post will correspond exactly to the positioning hole. At this time, the rebound force of the compression spring will push the movable block and the positioning post downward, so that the positioning post is inserted into the positioning hole and locked, thus completing the installation of the brush plate, reducing operation steps and improving installation convenience.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. When using this utility model, if it is necessary to disassemble the brush plate, the locking mechanism can be used to remove the limit on the card block, so that the card block can be pulled out of the slot, thereby completing the disassembly and assembly of the brush plate. This allows for timely disassembly and replacement of the brush when it is damaged, thus avoiding any impact on the iron removal effect and ensuring the long-term stable operation of the equipment.

[0015] 2. When using this utility model, when installation is required, insert the card block into the slot, then press the movable block. The movable block drives the positioning pin to move down, so that the positioning pin is inserted into the positioning hole, thereby limiting and fixing the card block.

[0016] 3. When this utility model is used, the design of the compression spring can improve the stability of the positioning post in the positioning hole when the positioning post is inserted into the positioning hole, and prevent the positioning post from moving upward.

[0017] 4. When this utility model is used, after the card block is fully pushed into the slot, the lower end of the positioning post will correspond exactly to the positioning hole. At this time, the rebound force of the compression spring will push the movable block and the positioning post down, so that the positioning post is inserted into the positioning hole to lock, thereby completing the installation of the brush plate, reducing operation steps and improving installation convenience.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0025] A metal removal device for wood pulp, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: It includes a fixed frame 100 and a brush plate 500. The fixed frame 100 is connected to a conveyor belt 201 via a conveyor roller 200. A magnetic roller 300 is also installed at the center of the fixed frame 100. A fixed block 400 is provided at the end of the fixed frame 100. A slot 401 is opened at the end of the fixed block 400. Both ends of the brush plate 500 are fixed with locking blocks 502. The locking blocks 502 are engaged in the slots. A brush 501 is provided on one side wall of the brush plate 500. The brush 501 is in close contact with the surface of the conveyor belt 201. A locking mechanism is provided above the fixed block 400. The locking mechanism is used to limit and fix the locking blocks 502 into the slot 401.

[0026] When installing the brush plate 500, the staff inserts the fixing blocks 400 at both ends of the brush plate 500 into the slot 401. Then, the locking mechanism limits and fixes the card block 502 into the slot 401, thus completing the fixation of the brush plate 500. When it is necessary to disassemble the brush plate 500, the locking mechanism is used to release the limitation of the card block 502, so that the card block 502 can be pulled out from the slot 401, thus completing the disassembly and assembly of the brush plate 500. This allows for timely disassembly and replacement of the brush 501 when it is damaged, thereby avoiding any impact on the iron removal effect and ensuring the long-term stable operation of the equipment.

[0027] Specifically, the locking mechanism includes a through hole on the upper surface of the fixed block 400, in which a positioning pin 601 is inserted. The upper surface of the locking block 502 has a positioning hole 503. The lower end of the positioning pin 601 is inserted into the positioning hole 503. The upper end of the positioning pin 601 is provided with a movable block 600. By pulling the movable block 600, the positioning pin 601 can be disengaged or inserted into the positioning hole 503.

[0028] When the brush plate 500 needs to be disassembled, pull the movable block 600 upwards, causing the movable block 600 to move the positioning post 601 upwards, so that the positioning post 601 is disengaged from the positioning hole 503, thereby removing the limitation on the sliding direction of the card block 502. Then the card block 502 can be pulled out from the slot 401. When installation is required, insert the card block 502 into the slot 401, and then press the movable block 600. The movable block 600 moves the positioning post 601 downwards, so that the positioning post 601 is inserted into the positioning hole 503, thereby limiting and fixing the card block 502.

[0029] Specifically, springs 603 are provided on both sides of the lower surface of the movable block 600. The upper end of the spring 603 is fixed to the lower wall of the movable block 600, and the lower end of the spring 603 is fixed to the upper surface of the fixed block 400. Through the design of the compression spring, when the positioning post 601 is inserted into the positioning hole 503, the compression spring can improve the stability of the positioning post 601 in the positioning hole 503 and prevent the positioning post 601 from moving upward.

[0030] Specifically, the movable block 600 has through holes on both sides, and a guide rod 602 is installed through the through holes. The lower end of the guide rod 602 passes through the center of the spring 603 and is fixed to the upper wall of the fixed block 400. When the movable block 600 is pulled, the movable block 600 moves vertically along the height direction of the guide rod 602, thereby improving the stability of the movable block 600 and the positioning column 601 during the movement process.

[0031] Specifically, a limit block is provided at the upper end of the guide rod 602. The cross-sectional area of ​​the limit block is larger than the cross-sectional area of ​​the through hole of the movable block 600. The limit block is designed to limit the stroke of the movable block 600, thereby preventing the positioning post 601 from moving too far and dislodging from the through hole of the fixed block 400.

[0032] Specifically, the side of the positioning post 601 facing the opening of the slot 401 is set as an inclined surface. When the brush plate 500 needs to be installed, the locking block 502 is inserted into the slot opening, so that the locking block 502 contacts the inclined surface of the positioning post 601 and pushes the positioning post 601 upward. At this time, the positioning post 601 drives the movable block 600 to move upward synchronously, so that the movable block 600 stretches the compression spring. When the locking block 502 is fully pushed into the slot 401, the lower end of the positioning post 601 will correspond exactly to the positioning hole 503. At this time, the rebound force of the compression spring will push the movable block 600 and the positioning post 601 downward, so that the positioning post 601 is inserted into the positioning hole 503 to lock, thereby completing the installation of the brush plate 500, reducing operation steps and improving installation convenience.

[0033] It should be clarified that this utility model is mainly used for disassembling and assembling the brush plate 500. It should be noted that the magnetic roller 300, the fixing frame 100, the conveying roller 200 and the conveyor belt 201 are all devices that have been disclosed and explained in detail in the prior art CN 221085957U. Since they are not the main technical features of this utility model, the model is not limited here, nor is their structure described in detail. Their usage methods and other compatible structures are disclosed in CN 221085957U. This application only describes in detail the locking mechanism and the usage method and installation position of the brush plate 500.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
