Description

Technical Field

[0001] This application relates to the technical field of pulp filtration equipment, and in particular to a filtration device for a centrifugal pulping machine. Background Technology

[0002] During the production process, waste paper pulp contains various impurities, including small impurities with a density close to that of fibers, such as fine sand, lime powder, foam, oil, wax, and rubber, which can affect the quality of the paper products. Therefore, waste paper pulp needs to be filtered before entering the centrifugal pulping machine.

[0003] Reference Figure 6 Existing related technologies include a low-concentration slag removal device comprising a frame, a feed pipe, and two discharge pipes. Both the feed pipe and discharge pipes are horizontally connected to the frame. Several slag removal cones are arranged in an array along the length of the feed pipe on both sides. Each slag removal cone is connected to the same discharge pipe at its top and to a drain pipe at its bottom. The slag removal cones are bound to the frame with wire. The slurry enters the slag removal cones tangentially, generating centrifugal force that separates impurities from the slurry. The clean slurry concentrates at the center of the slag removal cone and moves towards the discharge pipe at one end of the cone, thus achieving the purpose of slurry purification.

[0004] Regarding the aforementioned technologies, the inventors believe that the existing technology uses wire to fix the slag removal cones, which requires binding each cone individually during installation, making it inconvenient. Furthermore, if the equipment is located outdoors, the binding parts are prone to corrosion and breakage, resulting in insufficient stability. Utility Model Content

[0005] To address the inconvenience of installing the slag removal cone in existing technologies, this application provides a filtration device for a centrifugal pulper.

[0006] The following technical solution is adopted:

[0007] A filtration device for a centrifugal pulper includes a frame, a feed pipe, and two discharge pipes. Both the feed pipe and the discharge pipes are horizontally connected to the frame. A plurality of slag-removing cones are arranged in an array along the length of each feed pipe. One end of each row of slag-removing cones is connected to the same discharge pipe, and the other end is connected to a drain pipe. A support base is also provided on the frame. The support base is horizontally arranged along one row of slag-removing cones. Several positioning grooves are formed along the length of the support base to allow the slag-removing cones to enter the support base. The support base is located away from... A fixed base is detachably connected to one side of the frame. The fixed base has several clearance slots that correspond to the positions of several positioning slots. The positioning slots cooperate with the clearance slots to allow the support base and the fixed base to be fitted onto the slag removal cone. A limiting block that can move closer to or further away from the slag removal cone is slidably connected in the fixed base. The limiting block can move to abut against the slag removal cone and cause the slag removal cone to abut against the support base. A control component that causes several limiting blocks to move simultaneously is provided on the side of each row of limiting blocks away from the slag removal cone.

[0008] By adopting the above technical solution, the slag removal cone is placed in the positioning groove. The adjustment and control component drives the limiting block to move towards the slag removal cone until it abuts against the slag removal cone. The slag removal cone is fixed by clamping it with the limiting block and the support seat. This avoids the step of binding each slag removal cone individually as in the existing solution, which improves efficiency and facilitates maintenance. When maintenance is required on a certain slag removal cone, the slag removal cone can be disassembled simply by loosening the limiting block with the control component.

[0009] Optionally, the control assembly includes a control cable, an elastic element, and a rotating column. The control cable abuts against the side of the plurality of limiting blocks away from the slag removal cone. One end of the control cable is connected to the elastic element, and the elastic element always keeps the control cable taut. The other end of the control cable is connected to the rotating column, which is rotatably connected to the fixed seat. The rotating column is provided with a fixing element that restricts its continued rotation after it rotates.

[0010] By adopting the above technical solution, the rotating column is controlled to keep the control cable in a relaxed or taut state, so that the limiting block driven by the control cable is pressed against or moves away from the slag removal cone, thereby achieving the purpose of controlling several limiting blocks at the same time, which facilitates the fixing of the slag removal cone.

[0011] Optionally, the limiting block is provided with a cable routing groove for the control cable to be mounted therein.

[0012] By adopting the above technical solution, the control cable can be prevented from shifting during operation, thus avoiding the situation where the mechanism becomes difficult to use.

[0013] Optionally, the fixed base may also be provided with a plurality of tensioning rollers for tensioning the control cable along the control cable path.

[0014] By adopting the above technical solution, when the control cable needs to press the limiting block against the slag removal cone, the tensioning roller brings the control cable closer to the support seat, so that the control cable can be more taut and the limiting force of the limiting block on the slag removal cone is greater.

[0015] Optionally, one end of the rotating column is provided with a rotating block for easy rotation by hand, and the fixing member is a fixing pin that passes through the rotating block. The fixing seat has several fixing holes arranged in a circular array along the circumference of the rotating column on the outer wall of the side near the rotating block, and the fixing pin passes through the rotating block and enters any of the fixing holes.

[0016] By adopting the above technical solution, the rotating block is rotated to drive the limiting block to press against the slag removal cone. After reaching the appropriate position, the rotating block is fixed by the fixing pin to limit the continued rotation of the rotating column, thereby fixing the slag removal cone.

[0017] Optionally, the limiting block is an arc shape with an inner diameter equal to the outer diameter of the slag removal cone abutment portion.

[0018] By adopting the above technical solution, the limiting block can fit more closely to the slag removal cone, thereby providing better fixation for the slag removal cone.

[0019] Optionally, the limiting block is further provided with a guide block, and the fixed seat is provided with a guide groove for the guide block to slide.

[0020] By adopting the above technical solution, guidance is provided for the restriction block, preventing the restriction block from shifting during movement.

[0021] Optionally, the elastic element is a coil spring.

[0022] By adopting the above technical solution, a method is provided to keep the control cable taut at all times. By using a coil spring to retract the control cable, the internal space of the fixing base is saved.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. A more convenient method for fixing the slag removal cone is provided, which only requires controlling the rotating column to make several limiting blocks push several slag removal cones against the support base to fix the slag removal cone;

[0025] 2. The slag removal cone can be disassembled simply by removing the fixing pin, which makes it convenient for staff to maintain the slag removal cone. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 To be continued Figure 6 This application will be described in further detail.

[0034] Reference Figure 1 This application discloses a filtration device for a centrifugal pulper, including a frame 1, a feed pipe 11, and two discharge pipes 12. The feed pipe 11 and discharge pipes 12 are both horizontally connected to the frame 1. For the sake of simplicity in the drawings, this embodiment only shows ten slag removal cones 14. Five slag removal cones 14 are arranged in an array along the length of the feed pipe 11 on both sides. All ten slag removal cones 14 are connected to the feed pipe 11. The slag removal cones 14 are vertically arranged. The upper part of each slag removal cone 14 is connected to the same discharge pipe 12, and the lower part is connected to a drain pipe 13. The feed pipe 11, discharge pipe 12, and drain pipe 13 are all connected to their respective extension pipes to connect to other equipment.

[0035] The frame 1 is also integrally machined with a support base 2, which is a rectangular strip. The support base 2 is horizontally set along a slag removal cone 14. The support base 2 has five positioning grooves 21 along its length for several slag removal cones 14 to enter into the support base 2. The positioning grooves 21 are arc-shaped. A fixed base 3 is detachably connected to the side of the support base 2 away from the frame 1. The fixed base 3 has five clearance grooves 34 that correspond to the positions of the five positioning grooves 21. The clearance grooves 34 are rectangular. The positioning grooves 21 cooperate with the clearance grooves 34 to make the support base 2 and the fixed base 3 fit over the slag removal cones 14. The fixed base 3 has mounting bolts 35 at both ends. The mounting bolts 35 pass through the fixed base 3 and the support base 2 into the frame 1.

[0036] A limiting block 31 is slidably connected to the fixed base 3, which can move closer to or further away from the slag removal cone 14. The inner diameter of the limiting block 31 is an arc shape equal to the outer diameter of the contact part of the slag removal cone 14. The curvature of the positioning groove 21 is the same as that of the limiting block 31, so that the limiting block 31 can fit more closely to the slag removal cone 14, thereby providing better fixation for the slag removal cone 14. The limiting block 31 can be moved to abut against the slag removal cone 14 and cause the slag removal cone 14 to abut against the support base 2. On the side of each row of limiting blocks 31 away from the slag removal cone 14, a control component is provided to move five limiting blocks 31 simultaneously.

[0037] The control assembly includes a control cable 32, an elastic element, and a rotating column 33. The control cable 32 is a steel cable with an outer plastic layer. The control cable 32 abuts against the side of the limiting block 31 away from the slag removal cone 14. The limiting block 31 has a cable groove 311 for the control cable 32 to be inserted, preventing the control cable 32 from shifting during operation. One end of the control cable 32 is connected to the elastic element, which always keeps the control cable 32 taut. The elastic element is a coil spring 321 for winding the control cable 32. The other end of the control cable 32 is fixed to the outer wall of the rotating column 33. The rotating column 33 is rotatably connected to the fixed base 3. The rotating column 33 is provided with a fixing element that limits its continued rotation after it rotates. The rotating column 33 is controlled to keep the control cable 32 in a relaxed or taut state, so that the limiting block 31 driven by the control cable 32 abuts against or moves away from the slag removal cone 14, thereby achieving the purpose of simultaneously controlling the limiting block 31 and facilitating the fixation of the slag removal cone 14. The fixed base 3 is also provided with several tensioning rollers 322 for tensioning the control cable 32 along the path of the control cable 32. After the control cable 32 passes the limiting block 31, it will wrap around the tensioning roller 322 and then cooperate with the adjacent limiting block 31. When the control cable 32 needs to press the limiting block 31 against the slag removal cone 14, the tensioning roller 322 will bring the control cable 32 closer to the support base 2 so that the control cable 32 can be more taut and the limiting force of the limiting block 31 on the slag removal cone 14 is greater.

[0038] The limiting block 31 is also provided with a guide block 312, which is a rectangular strip. The fixed base 3 has a guide groove 313 for the guide block 312 to slide, which is a rectangular groove perpendicular to the length direction of the fixed base 3. This provides guidance for the limiting block 31 and prevents the limiting block 31 from deviating during movement.

[0039] One end of the rotating column 33 is provided with a rotating block 331 for easy manual rotation. The fixing element is a fixing pin 332 that passes through the rotating block 331. Several fixing holes 333 are arranged in a circular array along the outer wall of the fixing seat 3 near the rotating block 331. The fixing pin 332 passes through the rotating block 331 and enters any fixing hole 333. Rotating the rotating block 331 causes the limiting block 31 to press against the slag removal cone 14. After reaching a suitable position, the rotating block 331 is fixed by the fixing pin 332 to limit the continued rotation of the rotating column 33, thereby fixing the slag removal cone 14.

[0040] The implementation principle of the filtration device for a centrifugal pulper in this application embodiment is as follows:

[0041] Align the slag removal cone 14 with the support base 2, placing the slag removal cone 14 in the positioning groove 21. Cover it with the fixing base 3 and fix it with the mounting bolts 35. Adjust the rotating block 331 to drive the rotating column 33 to rotate, and rewind the control cable 32 to move the limiting block 31 towards the slag removal cone 14 until it abuts against the slag removal cone 14. After reaching a taut state, the rotating column 33 is restricted by the fixing pin 332. The limiting block 31 and the support base 2 clamp the slag removal cone 14 to achieve fixation. This avoids the step of binding each slag removal cone 14 individually as in existing solutions, improving efficiency and facilitating maintenance. When maintenance is required on a particular slag removal cone 14, it can be disassembled simply by loosening the limiting block 31 using the control component.

[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
