Description

Technical Field

[0001] This invention belongs to the field of waste recycling technology, specifically a device and method for processing household paper scraps. Background Technology

[0002] Since finished tissue paper is made by laminating single layers of tissue paper base paper and then processing it through cutting and packaging, a certain amount of scraps are generated during the production process. These scraps may contain impurities such as wrapping film and tape. Currently, tissue paper mills mainly use commercial wood pulp as raw material. Due to the price restrictions of imported pulp, 70% of the production cost of tissue paper mills is the cost of raw materials. Recycling and using 10%-20% of the tissue paper scraps to replace commercial wood pulp can reduce the raw material cost of tissue paper.

[0003] When waste paper is recycled, it is first broken down into pulp using a strong alkaline solution. Then, it is screened to remove large impurities and metals. The pulp is then recycled to a pulping tank. However, the pulp in the pulping tank will become cloudy and separate due to gravity during the settling process. Furthermore, the pipes that extract the pulp are usually located at fixed points in the pulping tank, so the quality of the extracted pulp is constantly changing. This leads to significant differences in the quality of the finished paper, so improvements are needed. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical solution adopted by the present invention to solve its technical problem is: a processing device for scrap paper of household use, including a liquid storage component, a discharge device is provided on the top of the liquid storage component, and a support base is provided on the bottom of the liquid storage component;

[0005] The liquid storage component includes an insulated outer cylinder, with a limiting device on the upper part of the inner wall of the insulated outer cylinder and an inner sliding device at the axis at the bottom of the inner wall of the insulated outer cylinder. Liquid delivery passages are symmetrically arranged on both the front and rear sides of the upper part of the inner cavity of the insulated outer cylinder through through-holes. The discharge device includes an annular rotating track, with surface rollers symmetrically arranged on both sides of the inner wall of the annular rotating track. A torque motor is fixedly connected to the axis of the inner wall of the surface rollers via a connecting rod. A grooved roller is fixedly connected to the outer surface of the output shaft of the torque motor, and a traction rod is tactilely connected to the outer surface of the grooved roller.

[0006] The support base includes an elevated bottom shell. A self-cleaning device is installed at the bottom of the inner wall of the elevated bottom shell. A drainage bottom cylinder is fixedly connected to the axis at the bottom of the inner cavity of the elevated bottom shell. A water pumping rod is rotatably connected to the inner wall of the drainage bottom cylinder. An isolation motor is fixedly connected to the bottom end of the water pumping rod. A conical drainage plate is fixedly connected to the outer surface of the isolation motor. A filling concave shell is fixedly connected to the axis at the top of the inner wall of the elevated bottom shell. A modified guide shaft is rotatably connected to the axis at the inner cavity of the filling concave shell. Inserted fixing rods are evenly arranged on the inner wall of the filling concave shell. The modified guide shaft is connected to the drainage bottom cylinder below. The pulp inside the insulation outer cylinder can be drained to the outside through the slot opened by the modified guide shaft.

[0007] The inner sliding device includes a soft sleeve, which is a hemispherical rubber sheet. A strap frame is used to bind the sides of the soft sleeve together at the top edge, and the side groove of the strap frame matches the guide strip on the inner wall of the insulation outer cylinder, ensuring that the soft sleeve can slide stably along the inner wall of the insulation outer cylinder. The inner cavity of the soft sleeve has evenly spaced fitting slots. A metal sleeve is fixedly connected to the axis of the inner cavity of the soft sleeve. Isolation slide plates are evenly arranged at the bottom of the inner wall of the metal sleeve, and a spring washer is fixedly connected to the top of the isolation slide plates. Because the strap frame is installed on the side of the soft sleeve, when the soft sleeve is at the bottom, i.e. Figure 4 When the position is shown, a space is reserved between the lower surface of the veneer and the inner wall of the filling recess for the self-cleaning equipment to drain and clean pulp residue.

[0008] Furthermore, the bottom of the inner cavity of the modified guide shaft is uniformly provided with vertical grooves. Both sides of the outer surface of the isolation slide plate are slidably connected to the inner cavity of the modified guide shaft through the vertical grooves. The bottom of the outer surface of the isolation slide plate is fixedly connected to the bottom of the inner wall of the metal sleeve through a fastener. The top of the spring washer is fixedly connected to the top of the outer surface of the modified guide shaft. The inner cavity of the facing soft sleeve is inserted into the outer surface of the plug-in fixing rod through an adapter socket. The upper part of the outer surface of the facing soft sleeve is slidably connected to the inner wall of the heat insulation outer cylinder through a strap frame. The top of the drainage bottom cylinder is rotatably connected to the bottom end of the modified guide shaft. The top of the outer surface of the metal sleeve is fixedly connected to the bottom end of the traction rod. The lower surface of the annular rotating track is fixedly connected to the top of the heat insulation outer cylinder. The outer surface of the traction rod is slidably connected to the axis at the top of the inner cavity of the heat insulation outer cylinder through a through-hole. There are four facing rollers, and the bottom ends of the facing rollers are slidably connected to the bottom of the inner wall of the annular rotating track through pulleys.

[0009] Furthermore, the self-cleaning device includes a built-in clean water tank, with pressurized drainage plates evenly distributed at the top of the inner cavity of the built-in clean water tank. A connecting pipe is fixedly connected to the top of the pressurized drainage plate, and a side-port plug is fixedly connected to the end of the connecting pipe away from the surface soft sleeve. Figure 7 As shown, each pressurized drainage plate supplies water through the inlet at the end of the connecting pipe away from the soft sleeve. Due to the pressurization effect of the pressurized drainage plate, the side port plug is pushed away from the soft sleeve by the water pressure, thus opening the inlet. When the pressurized drainage plate is not supplying water, the side port plug will block the inlet of the connecting pipe.

[0010] Furthermore, the outer surface of the built-in clean water tank is fixedly connected to the bottom of the inner wall of the elevated bottom shell, the bottom end of the pressurized diversion plate is fixedly connected to the top of the inner cavity of the built-in clean water tank through the water outlet, the outer surface of the pressurized diversion plate is fixedly connected to the inner wall of the elevated bottom shell, and the outer surface of the insertion pipe extends into the interior of the filling concave shell through the pipe groove.

[0011] Furthermore, the limiting device includes a fixed retaining ring, a pressure-sensitive washer is fixedly connected to the top of the inner cavity of the fixed retaining ring, a compression sleeve is evenly arranged on the lower surface of the pressure-sensitive washer, a wall-adhering strip is fixedly connected to the bottom end of the compression sleeve, and an auxiliary roller is rotatably connected to the lower surface of the wall-adhering strip.

[0012] Furthermore, the side of the fixing ring is fixedly connected to the inner wall of the insulation outer cylinder, the outer surface of the compression sleeve is slidably connected to the bottom of the inner cavity of the fixing ring, the end of the wall-adhering strip away from the compression sleeve is slidably connected to the inner wall of the insulation outer cylinder, and the upper part of the outer surface of the soft sleeve is pressed against the outer surface of the auxiliary roller shaft through the strap frame.

[0013] A high-consistency hydraulic pulper is used, with a pulping concentration of 12%-16% and a pulping temperature of 70℃-85℃. When processing high wet strength paper, a certain amount of chemical additives (caustic soda, wet strength dissociation agent, etc.) are added to ensure that the pH of the pulping is controlled between 12 and 14. Pulping is carried out for a certain period of time until there are no obvious pulp spots in the pulp. The pulped pulp is pumped through the pulper's screen plate to the inlet of the high-consistency desander. After passing through the high-consistency desander, larger impurities in the pulp are removed. The good pulp from the high-consistency desander then passes through an iron remover. The iron remover removes metal substances from recycled tissue paper. After passing through the iron remover, the pulp is stored in a discharge tower. The pulp in the discharge tower then passes through a low-consistency desander combined with a fine screening process. The prepared pulp is then transported to the paper machine's mixing tank. Finally, after passing through a leveling mill, the pulp is transported through the liquid conveying channel and stored in the liquid storage unit. The pulp in the liquid storage unit is then transported to the paper machine section for use through the conical guide plate at the bottom.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. Because the pulp in the pulping tank will become cloudy and separate due to gravity during the settling process, and the pulp extraction tube is usually located at a fixed point in the pulping tank, the quality of the extracted pulp is constantly changing, which will lead to significant differences in the quality of the finished paper. This device redesigns the internal structure of the heat-insulating outer cylinder. Through a sliding inner sliding device, the cloudy and separated pulp is mixed evenly by up-and-down oscillation before each pulp discharge, thereby avoiding the above-mentioned problems.

[0016] 2. This device does not use a fan blade agitation method to mix the pulp liquor. This avoids the problem of pulp accumulating towards a single axis or side position due to the vortex formed during pulp agitation. It also avoids the problem of high-speed rotating fan blades easily causing wear on the inner wall of the container, which would lead to an increase in the content of impurities and metals in the pulp and affect the final paper quality.

[0017] 3. This device discharges pulp from the bottom drain cylinder by modifying the groove of the guide shaft and the adapter plug of the soft sleeve. The double sealing can prevent the external air from flowing back into the container during pulp discharge, which would cause the pulp concentrate to be easily oxidized. When discharging pulp, the high-speed rotation of the pumping rod will accelerate the pulp discharge process. Therefore, when the pulp stored in the liquid storage component is relatively thick, it can also be discharged smoothly.

[0018] 4. Some pulp residue will remain at the base of the plug-in fixing rod. To avoid the pulp sticking to the inner wall of the veneer sleeve and the filling concave shell, the device leaves a space between the veneer sleeve and the filling concave shell. When the adapter plug is opened again for drainage, the groove of the modified guide shaft will be opened immediately after the isolation slide slides up, so this diluted pulp will be discharged first, thus achieving a cleaning effect and will not mix with the main discharged pulp.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0030] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a device for processing household paper scraps, including a liquid storage component 1, a discharge device 3 is provided on the top of the liquid storage component 1, and a support base 5 is provided on the bottom of the liquid storage component 1;

[0031] The liquid storage component 1 includes an insulated outer cylinder 11. A limiting device 2 is provided on the upper part of the inner wall of the insulated outer cylinder 11. An inner sliding device 4 is provided at the axis at the bottom of the inner wall of the insulated outer cylinder 11. Liquid delivery passages 12 are symmetrically provided on the front and rear sides of the upper part of the inner cavity of the insulated outer cylinder 11 through through openings. The discharge device 3 includes an annular rotating track 31. Surface rollers 32 are symmetrically provided on both sides of the inner wall of the annular rotating track 31. A torque motor 33 is fixedly connected to the axis of the inner wall of the surface roller 32 through a connecting rod. A grooved roller 34 is fixedly connected to the outer surface of the output shaft of the torque motor 33. A traction rod 35 is rolledly connected to the outer surface of the grooved roller 34.

[0032] The support base 5 includes an elevated base shell 51. A self-cleaning device 6 is installed at the bottom of the inner wall of the elevated base shell 51. A drainage bottom cylinder 55 is fixedly connected to the axis at the bottom of the inner cavity of the elevated base shell 51. A water pumping rod 54 is rotatably connected to the inner wall of the drainage bottom cylinder 55. An isolation motor 53 is fixedly connected to the bottom end of the water pumping rod 54. A conical drainage plate 52 is fixedly connected to the outer surface of the isolation motor 53. A filling concave shell 56 is fixedly connected to the axis at the top of the inner wall of the elevated base shell 51. A modified guide shaft 58 is rotatably connected to the axis at the inner cavity of the filling concave shell 56. Insertion fixing rods 57 are evenly arranged on the inner wall of the filling concave shell 56. The modified guide shaft 58 is connected to the drainage bottom cylinder 55 below. The pulp inside the heat-insulating outer cylinder 11 can be drained to the outside through the slot opened by the modified guide shaft 58.

[0033] The inner sliding device 4 includes a soft sleeve 41, which is a hemispherical rubber sheet. A strap frame is used to bind the sides of the soft sleeve 41 together at the top edge, and the side groove of the strap frame matches the guide strip on the inner wall of the insulation outer cylinder 11, ensuring that the soft sleeve 41 can slide stably along the inner wall of the insulation outer cylinder 11. The inner cavity of the soft sleeve 41 has evenly spaced fitting slots 42. A metal sleeve 43 is fixedly connected to the axis of the inner cavity of the soft sleeve 41. Isolation slide plates 44 are evenly arranged at the bottom of the inner wall of the metal sleeve 43, and a spring pad 45 is fixedly connected to the top of the isolation slide plate 44. Because the strap frame is installed on the side of the soft sleeve 41, when the soft sleeve 41 is at its lowest position, i.e. Figure 4 When the position is shown, a space is reserved between the lower surface of the veneer sleeve 41 and the inner wall of the filling recess 56 for the self-cleaning device 6 to drain and clean pulp residue.

[0034] The bottom of the inner cavity of the modified guide shaft 58 is uniformly provided with vertical grooves. Both sides of the outer surface of the isolation slide plate 44 are slidably connected to the inner cavity of the modified guide shaft 58 through the vertical grooves. The bottom of the outer surface of the isolation slide plate 44 is fixedly connected to the bottom of the inner wall of the metal sleeve 43 through a fastener. The top of the spring pad 45 is fixedly connected to the top of the outer surface of the modified guide shaft 58. The inner cavity of the face-fitting soft sleeve 41 is inserted into the outer surface of the insertion fixing rod 57 through the adapter insertion port 42. The upper part of the outer surface of the face-fitting soft sleeve 41 is slidably connected to the inner wall of the heat-insulating outer cylinder 11 through the strap frame. The top of the drainage bottom cylinder 55 is rotatably connected to the bottom end of the modified guide shaft 58. The top of the outer surface of the metal sleeve 43 is fixedly connected to the bottom end of the traction rod 35. The lower surface of the annular rotating track 31 is fixedly connected to the top of the insulation outer cylinder 11. The outer surface of the traction rod 35 is slidably connected to the axis at the top of the inner cavity of the insulation outer cylinder 11 through the through-hole. There are four surface-applying rollers 32, and the bottom end of the surface-applying rollers 32 is slidably connected to the bottom of the inner wall of the annular rotating track 31 through a pulley.

[0035] After the pulp is guided into the interior of the insulation outer cylinder 11 through the liquid delivery channels 12 on both sides, the pulp will accumulate on the upper part of the facing soft sleeve 41 because the inner sliding device 4 is located at the bottom of the inner wall of the insulation outer cylinder 11. As time goes by, the pulp will become cloudy and separate due to gravity during the standing process.

[0036] When discharging pulp liquor, the top discharge device 3 lifts the traction rod 35 upward by rotating the grooved rollers 34 on both sides. At this time, the bottom end of the traction rod 35 drives the metal sleeve 43 to rise. The metal sleeve 43 pulls the core of the facing soft sleeve 41 to rise. At this time, the facing soft sleeve 41 is pulled out from the plug-in fixing rod 57, and the groove of the modified guide shaft 58 is opened by pulling the isolation slide plate 44. Since the hydraulic pressure acts on the inner wall of the facing soft sleeve 41, and the force point of the facing soft sleeve 41 is located at the core, the spherical shape of the facing soft sleeve 41 will change during the movement. The pressure below the facing soft sleeve 41 will continuously decrease due to the air suction effect of the pumping rod 54 until the plug-in fixing rod 57 separates from the adapter plug 42. The pulp on the facing soft sleeve 41 is discharged through the adapter plug 42, the groove opened by the modified guide shaft 58, and the drainage bottom cylinder 55.

[0037] As the veneer sleeve 41 slides up and down along the modified guide shaft 58, as long as the plug-in fixing rod 57 does not slide out of the adapter plug 42, the pulp is always isolated above the veneer sleeve 41. Therefore, the traction rod 35 can be controlled to slide up and down by the reciprocating rotation of the groove roller 34, thereby agitating the pulp inside the insulation outer cylinder 11 and making the already turbid and separated pulp remixed evenly. In this way, when the adapter plug 42 is opened to discharge the pulp, the quality of the pulp flowing through the bottom cylinder 55 can be guaranteed to be almost the same.

[0038] When the traction rod 35 pulls the facing sleeve 41 up to the position between the guide strip of the insulation outer cylinder 11 and the limiting device 2, since there is no longer a vertical sliding restriction on the inner wall of the insulation outer cylinder 11, the facing roller 32 can rotate around the inner wall of the annular rotating track 31, twisting the traction rod 35, causing the facing sleeve 41 to rotate, so that the pulp inside forms a vortex, creating a stirring effect, thereby avoiding the problem of insufficient pulp mixing caused by the facing sleeve 41 oscillating in one direction.

[0039] After the pulp discharge is completed, the discharge device 3 presses down the metal sleeve 43 through the traction rod 35. Under the pressure and the compression force of the internal spring washer 45, the metal sleeve 43 inserts the faceplate soft sleeve 41 into the plug-in fixing rod 57 and returns to the initial state. At this time, the isolation slide plate 44 also blocks the groove of the modified guide shaft 58 to further prevent pulp leakage.

[0040] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: Based on Embodiment 1, the self-cleaning device 6 includes a built-in clean water tank 61, with pressurized drainage plates 62 evenly arranged on the top of the inner cavity of the built-in clean water tank 61. A connecting pipe 63 is fixedly connected to the top of the pressurized drainage plate 62, and a side-port sliding plug 64 is fixedly connected to the end of the connecting pipe 63 away from the surface soft sleeve 41. Figure 7 As shown, each pressurized drainage plate 62 supplies water through the inlet of the end of the connecting pipe 63 away from the soft sleeve 41. Due to the pressurization effect of the pressurized drainage plate 62, the side port sliding plug 64 is pushed away from the soft sleeve 41 by the water pressure, thereby opening the inlet. When the pressurized drainage plate 62 is not supplying water, the side port sliding plug 64 will block the inlet of the connecting pipe 63.

[0041] The outer surface of the built-in clean water tank 61 is fixedly connected to the bottom of the inner wall of the suspended bottom shell 51. The bottom end of the pressurized diversion plate 62 is fixedly connected to the top of the inner cavity of the built-in clean water tank 61 through the water outlet. The outer surface of the pressurized diversion plate 62 is fixedly connected to the inner wall of the suspended bottom shell 51. The outer surface of the insertion pipe 63 extends to the interior of the filling concave shell 56 through the pipe groove.

[0042] The limiting device 2 includes a fixed retaining ring 21. A pressure-sensitive washer 25 is fixedly connected to the top of the inner cavity of the fixed retaining ring 21. A compression sleeve 22 is evenly arranged on the lower surface of the pressure-sensitive washer 25. A wall-adhering strip 23 is fixedly connected to the bottom end of the compression sleeve 22. An auxiliary roller shaft 24 is tumbledly connected to the lower surface of the wall-adhering strip 23.

[0043] The side of the fixing ring 21 is fixedly connected to the inner wall of the insulation outer cylinder 11, the outer surface of the compression sleeve 22 is slidably connected to the bottom of the inner cavity of the fixing ring 21, the end of the wall-adhering strip 23 away from the compression sleeve 22 is slidably connected to the inner wall of the insulation outer cylinder 11, and the upper part of the outer surface of the surface-adhering soft sleeve 41 is pressed against the outer surface of the auxiliary roller shaft 24 through the strap frame.

[0044] Some pulp residue will remain at the base of the plug-in fixing rod 57. To prevent the pulp from sticking the inner wall of the facing sleeve 41 and the filling concave shell 56 together, the device reserves some space between the facing sleeve 41 and the filling concave shell 56. When the pulp is stored above the facing sleeve 41, the built-in clean water tank 61 will inject clean water into the area between the facing sleeve 41 and the filling concave shell 56 through the pressurized diversion plate 62 and the plug-in pipe 63. At this time, the clean water will dilute the pulp and prevent the pulp from drying and sticking to the base of the plug-in fixing rod 57. When the adapter plug 42 is opened again for the next liquid drainage operation, the groove of the modified guide shaft 58 will be opened immediately after the isolation slide plate 44 slides up, so this diluted pulp will be discharged first, thereby achieving a cleaning effect and will not mix with the main discharged pulp.

[0045] When the traction rod 35 lifts the facing soft sleeve 41 upward, the limit device 2 will prevent the facing soft sleeve 41 from sliding excessively. At this time, the side tightening frame of the facing soft sleeve 41 will press the upper wall strip 23 through the auxiliary roller 24. The wall strip 23 will trigger the pressure-sensitive washer 25 by squeezing the compression sleeve 22. At this time, the discharge device 3 can no longer pull the facing soft sleeve 41 upward, which also means that the facing soft sleeve 41 is separated from the guide strip of the insulation outer cylinder 11. The facing soft sleeve 41 can rotate. When the facing soft sleeve 41 is twisted, the upper auxiliary roller 24 will rotate relative to the tightening frame of the facing soft sleeve 41, thereby reducing the frictional resistance of the facing soft sleeve 41.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
