Description

Technical Field

[0001] The invention belongs to the technical field of papermaking equipment, and in particular relates to a heavy slag remover for pulp and a working method thereof. Background Art

[0002] A slag remover is a device that uses the centrifugal principle to remove impurities in slurry with a density different from that of the slurry. The upper part of the slag remover is made of stainless steel, the lower part is injection-molded with polyurethane material, and the inner wall of the main body is designed as a spiral cone. The slag remover can be used in various slurry purification systems, mainly to remove heavy impurities such as sand, iron filings, etc. with a density greater than that of the slurry (heavy slag remover) and light impurities such as mixed adhesives, paraffin, hot melt adhesive, plastic sheets, foam, gas, ink particles, etc. with a density less than that of the slurry (light slag remover).

[0003] In the prior art, when the heavy-weight low-concentration slag remover is working, various impurities cause serious wear on the inner wall of the slag remover shell and the side wall of the slag discharge port. The entire shell often needs to be replaced due to the wear of the inner wall, and the slag discharge port is often damaged by impact when discharging impurities. The damage to the slag discharge port and the wear of the inner wall are difficult to repair and often require the replacement of the entire shell, which requires a high cost to replace the entire shell.

[0004] The utility model patent with application number CN202323362270.0 discloses a heavy-duty low-concentration slag remover for waste paper pulp, comprising an outer shell; the upper surface of the outer shell is fixedly connected to an inner shell; the upper surface of the inner shell is fixedly connected to a third shell; the upper surface of the third shell is fixedly connected to a pulp outlet; the outer circumferential surface of the third shell is fixedly connected to a pulp inlet; the lower surface of the outer shell is fixedly connected to a slag discharge pipe; the lower surface of the slag discharge pipe is fixedly connected to a No. 5 flange; the outer circumferential surface of the slag discharge pipe is fixedly connected to a limiting ring. When the inner shell needs to be replaced, turn the No. 1 bolt to make the No. 1 nut leave the No. 1 bolt, remove the outer shell, move the No. 3 flange upward to make the No. 3 flange leave the first shell, and then After that, the inner shell can be taken out from the first shell, and the inner shell can be replaced. The new second shell is slid to the inner bottom surface of the first shell through the sliding bar, and then the No. 3 flange is placed on the top of the No. 1 flange. The fixing ring will squeeze the second shell, and then the No. 1 flange and the No. 3 flange are fixed by the No. 1 bolt and the No. 1 nut, thereby realizing the rapid replacement of the inner shell and improving the work efficiency. When the slag discharge pipe needs to be replaced or cleaned, the No. 2 bolt is turned to make the No. 2 nut leave the No. 2 bolt, the No. 5 flange is removed, and the slag discharge pipe is removed from the first shell, so that the slag discharge pipe can be replaced, thereby improving the efficiency. However, the following defects still exist in actual production:

[0005] When there are too many heavy impurities in the equipment and it needs to be cleaned, the equipment needs to be disassembled, cleaned and replaced, which makes the equipment processing time longer and the processing efficiency lower, and then causes the pulp processing to be stopped for a long time, thus affecting the pulp processing efficiency.

[0018] Further optimization: The present invention also discloses a working method of a heavy-duty slag remover for pulp. Based on the above-mentioned heavy-duty slag remover for pulp, the working method comprises the following steps:

[0019] S1. Heavy Pulp Removal: The pulp enters the liquid inlet cylinder from the liquid inlet pipe in the reverse direction along the inner wall tangent of the liquid inlet cylinder. The pulp flows in a spiral manner inside the liquid inlet cylinder and the conical cylinder. The fibers and heavy particles are separated under the action of centrifugal force and gravity. The heavy particles remain in the conical cylinder, and the good pulp is discharged from the liquid outlet pipe.

[0020] S2. Conversion: Stop pulp injection, drive the longitudinal shaft to rotate, and change the working position of the two conical cylinders. During the rotation process, under the action of the limit lever, the two conical cylinders are turned upside down;

[0021] S3. Fixed seal: After the working position and up-down direction of the two conical cylinders are changed, the longitudinal moving arm moves downward, pushing the clamping rod downward to engage in the clamping slot hole to fix the two conical cylinders, and at the same time pushing the pressing rod upward to press the annular sealing gasket and the first sealing plate to seal;

[0022] S4. Cleaning: The longitudinal arm moves downward to connect the water inlet pipe with the water trough, and the inverted conical cylinder is flushed with water.

[0023] Beneficial effects:

[0024] By setting conical cylinders at both ends of the horizontal rotating shaft and the two conical cylinders in opposite directions, one upright conical cylinder is located below the liquid inlet cylinder to perform slag removal work, while the other conical cylinder is inverted above the receiving box to perform cleaning work, which simplifies the replacement steps of slag removal and cleaning and improves work efficiency;

[0025] When the conical cylinder is upright, the upper part of the movable rod is completely located inside the rod groove under the action of elastic force, so that the water hole is closed, thereby effectively blocking the rod groove, making it convenient for the conical cylinder to perform slag removal work; after the conical cylinder is inverted, the movable rod is forced to move downward, so that the water hole enters the interior of the conical cylinder, and at the same time the longitudinal arm moves downward to connect the water inlet pipe with the water groove, making it convenient to pass water into the interior of the conical cylinder for flushing;

[0026] When the longitudinal arm moves downward, the top plate is pushed downward, so that the clamping rod is clamped into the clamping slot hole on the horizontal rotating shaft, and the two conical cylinders are clamped and fixed, thereby improving the stability of slag removal and cleaning. At the same time, the top plate generates pressure on the pressure rod, pushing the pressure rod to swing upward, so that the annular sealing gasket is pressed and sealed with the first sealing plate at the bottom of the liquid inlet cylinder, thereby improving the sealing effect during slag removal.

[0048] The rotation control component 4 includes a longitudinal rotating shaft 401, which is rotatably installed in the middle of the support base 1. The bottom end of the longitudinal rotating shaft 401 is fixedly connected to a driven gear 402. A drive motor 404 is fixedly installed below the support base 1. The output end of the drive motor 404 is transmission-connected to a driving gear 403, and the driven gear 402 is meshed with the driving gear 403.

[0049] A clamping control member 405 is installed at the top end of the longitudinal rotating shaft 401 , and the clamping control member 405 is used to install and replace the processing component 3 .

[0050] The card-connecting control component 405 includes a fixed block 4051, which is fixedly installed on the top of the longitudinal rotating shaft 401.

Four guide rods 4056 are fixedly installed on the top surface of the fixed block 4051. The top plate 4055 is slidably connected to the guide rod 4056.

[0052] A pressing drive member 406 is provided on both sides of the fixing block 4051 , and the two pressing drive members 406 are symmetrically arranged.

[0053] The clamping drive member 406 includes a horizontal platform 4061, which is fixedly connected to the fixed block 4051. Two support plates 4062 are symmetrically fixed to the top surface of the horizontal platform 4061. A fixed shaft 4063 is fixed between the two support plates 4062. A rotating sleeve 4064 is rotatably connected to the fixed shaft 4063. A pressure rod 4065 is installed on the side of the rotating sleeve 4064 close to the top plate 4055. The end of the pressure rod 4065 away from the rotating sleeve 4064 is located below the top plate 4055. A pressing rod 4066 is installed on the side of the rotating sleeve 4064 away from the top plate 4055. The end of the pressing rod 4066 away from the rotating sleeve 4064 is located below the pressure plate 3035.

[0054] Two torsion springs 4067 are sleeved on the fixed shaft 4063 . One end of the torsion spring 4067 is fixedly connected to the rotating sleeve 4064 , and the other end is fixedly connected to its corresponding support plate 4062 .

[0055] This design pushes the top plate 4055 downward, so that the clamping rod 4054 is clamped into the clamping slot 305 on the horizontal rotating shaft 301, and then fixes the conical cylinder 302 at both ends of the horizontal rotating shaft 301, thereby improving the stability of slag removal and cleaning. At the same time, the top plate 4055 generates pressure on the pressure rod 4065, pushing the pressure rod 4066 to swing upward, so that the annular sealing gasket 3033 is pressed and sealed with the liquid inlet processing component 2, thereby improving the sealing effect of slag removal.

[0056] A liquid inlet processing component 2 is provided at the fixed liquid inlet and outlet station, and the liquid inlet processing component 2 and the conical cylinder 302 are combined together to form a slag removal component.

[0057] The liquid inlet processing component 2 includes a liquid inlet cylinder 201, which is fixedly installed above the support seat 1 through a first fixed frame. The liquid inlet cylinder 201 is fixedly installed with a liquid inlet pipe 202 along the tangential direction of the outer wall. The top of the liquid inlet cylinder 201 is fixedly installed with a liquid outlet pipe 203, and the bottom of the liquid inlet cylinder 201 is fixedly installed with a first sealing plate 204.

[0058] A rotation adjustment component 8 is provided at the turning and rotating station for turning the conical cylinder 302 .

[0059] The rotation adjustment assembly 8 includes a second fixing frame 801, which is fixed to the top surface of the support base 1. The top of the second fixing frame 801 is fixed to a side close to the longitudinal rotation axis 401 with a limit rod 802, and the height position of the limit rod 802 is lower than the horizontal rotation axis 301.

[0060] A receiving component is provided at the cleaning station.

[0061] The receiving assembly includes a receiving box 7 , which is fixed to the top surface of the support base 1 .

[0062] A mobile driving assembly 5 is provided at the fixed pressing water inlet station.

[0063] The mobile drive assembly 5 includes a sliding frame 501, which is fixed to the top surface of the support base 1. A longitudinal movement arm 502 is slidably connected to the sliding frame 501, and a push rod 505 is fixed to the bottom surface of the longitudinal movement arm 502 near one end of the top plate 4055.

[0064] A screw rod 503 is rotatably installed inside the sliding frame 501 , and the longitudinal moving arm 502 is threadedly connected to the screw rod 503 . A rotating motor 504 is fixedly installed on the top of the sliding frame 501 , and the output end of the rotating motor 504 is transmission-connected to the screw rod 503 .

[0065] A positioning water inlet component is provided on one side of the longitudinal arm 502 close to the receiving box 7. When the cleaning station is working, the inverted conical cylinder 302 is located below the positioning water inlet component. The positioning water inlet component, the conical cylinder 302 and the receiving box 7 are combined into a cleaning component.

[0066] The positioning water inlet component includes a side plate 506 fixedly connected to one side of the longitudinal arm 502 , a water inlet pipe 508 is installed on the side plate 506 , and two positioning rods 507 are symmetrically installed on the bottom surface of the side plate 506 .

[0067] With this design, when the conical cylinder 302 is upright, the upper part of the movable rod 3043 is completely located inside the rod groove 3042 under the action of the spring force, so that the water hole 3047 is closed, making it convenient for the conical cylinder 302 to perform the slag removal work; when the conical cylinder 302 is inverted, the water inlet pipe 508 pushes the movable rod 3043 to move downward, so that the water hole 3047 enters the interior of the conical cylinder 302. At the same time, the water inlet pipe 508 is connected to the water groove 3046, making it convenient to pass water into the interior of the conical cylinder 302 for flushing.

[0068] During operation, the liquid inlet pipe 202 is connected to the output end of the feed box, and the liquid outlet pipe 203 is connected to the input end of the discharge box. The pulp to be processed enters the liquid inlet cylinder 201 from the liquid inlet pipe 202 along the tangent direction of the inner wall of the liquid inlet cylinder 201. The pulp enters the liquid inlet cylinder 201 from the liquid inlet pipe 202 at a certain pressure and speed, which can form a high-speed rotating vortex after entering the liquid inlet cylinder 201, providing power for subsequent impurity separation. Under the action of the vortex, due to the influence of centrifugal force, heavy impurities are thrown to the inner wall of the liquid inlet cylinder 201, while light fibers gather in the central area, thereby preliminarily realizing the separation of fibers and heavy impurities.

[0069] Then the slurry flows downward in the conical cylinder 302. As the rotation radius gradually decreases, the centrifugal force further increases, making the separation effect of heavy impurities and fibers more obvious. The taper design of the conical cylinder 302 will affect the flow speed and centrifugal force distribution of the slurry, thereby affecting the slag removal effect. After separation, the fiber slurry located at the center of the vortex flows upward and is discharged from the liquid outlet pipe 203 to enter the subsequent papermaking process. Finally, the heavy impurities remain in the conical cylinder 302 under the action of centrifugal force and gravity.

[0070] When there are too many heavy impurities in the conical cylinder 302 located below the liquid inlet cylinder 201, which affects the separation of the fibers and heavy impurities, the staff needs to suspend the introduction of the slurry, and then start the rotating motor 504 to drive the screw 503 to rotate, and the longitudinal arm 502 moves upward to drive the push rod 505 to move upward. The top plate 4055 drives the clamping rod 4054 to move upward under the elastic force of the third spring 4057, and disengages from the clamping slot hole 305. Synchronously, the side plate 506 moves upward, and the water inlet pipe 508 disengages from the water trough 3046 on the inverted conical cylinder 302; the pressing rod 4066 below the liquid inlet cylinder 201 no longer presses the pressure plate 3035 installed on the upright conical cylinder 302.

[0071] Then start the drive motor 404, drive the longitudinal rotating shaft 401 to rotate counterclockwise, and then drive the two conical cylinders 302 to exchange positions between the fixed liquid inlet and outlet station and the cleaning station. After the upright conical cylinder 302 contacts the limit stop rod 802, under the limiting action of the limit stop rod 802, the upright conical cylinder 302 flips to an inverted state, and drives the other conical cylinder 302 to flip to an upright state through the transverse rotating shaft 301. After the transverse rotating shaft 301 rotates horizontally 180°, the drive motor 404 stops, and the two conical cylinders 302 stop below the liquid inlet cylinder 201 and above the receiving box 7 respectively.

[0072] Then start the rotating motor 504 to drive the longitudinal arm 502 to move downward, and position the inverted conical cylinder 302 through the two symmetrically arranged positioning rods 507 to reduce the swing of the conical cylinder 302. At the same time, dock the water inlet pipe 508 and the water trough 3046, and push the movable rod 3043 to move downward, so that the water hole 3047 enters the interior of the conical cylinder 302. The top of the water inlet pipe 508 is connected to the water tank through a hose, and the water tank pump is turned on. After water enters from the water inlet pipe 508, it is sprayed out from the water hole 3047 and flushed on the inner wall of the conical cylinder 302 under the guidance of the guide block 3048, and the heavy impurities on the inner wall of the conical cylinder 302 are flushed into the receiving box 7 to complete the cleaning work.

[0073] When the longitudinal arm 502 moves downward, it pushes the clamping rod 4054 to move downward, so that the clamping rod 4054 is clamped into the clamping slot 305 in the horizontal rotating shaft 301, and the two conical cylinders 302 are fixed in position. At the same time, the top plate 4055 moves downward to generate downward pressure on the pressure rod 4065, driving the rotating sleeve 4064 to rotate, so that the pressing rod 4066 swings upward, and generates upward pressure on the pressure plate 3035 on the conical cylinder 302 below the liquid inlet cylinder 201. The pressure plate 3035 overcomes the spring force and moves upward and drives the annular sealing gasket 3033 to move upward, so that the annular sealing gasket 3033 presses and seals the first sealing plate 204 at the bottom end of the liquid inlet cylinder 201, thereby improving the sealing effect during slag removal.

[0074] The present invention also discloses a working method of a heavy-duty slag remover for pulp. Based on the above-mentioned heavy-duty slag remover for pulp, the working method comprises the following steps:

[0075] S1. Heavy material removal: The pulp flows from the liquid inlet pipe 202 into the liquid inlet cylinder 201 in the opposite direction along the inner wall tangent of the liquid inlet cylinder 201. The pulp flows in a spiral manner inside the liquid inlet cylinder 201 and the conical cylinder 302. Under the action of centrifugal force and gravity, the fiber and heavy materials are separated. The heavy materials remain in the conical cylinder 302, and the good pulp is discharged from the liquid outlet pipe 203.

[0076] S2. Switching: Stop pulp injection, drive the longitudinal rotating shaft 401 to rotate, and change the working position of the two conical cylinders 302. During the rotation process, under the action of the limit stop lever 802, the two conical cylinders 302 are turned upside down;

[0077] S3. Fixed seal: After the working position and up-down direction of the two conical cylinders 302 are changed, the longitudinal movement arm 502 moves downward, pushing the clamping rod 4054 downward to engage in the clamping slot 305, thereby fixing the two conical cylinders 302. At the same time, the pressing rod 4066 is pushed upward to press the annular sealing gasket 3033 and the first sealing plate 204 together for sealing.

[0078] S4. Cleaning: The longitudinal arm 502 moves downward, so that the water inlet pipe 508 is docked with the water trough 3046, and the inverted conical cylinder 302 is flushed with water.

[0079] For those skilled in the art, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
