A pulp recovery mechanism for a pulping machine

Abstract

This utility model discloses a pulp recovery mechanism for a pulping and finishing machine, relating to the technical field of pulp recovery. It solves the problem that the debris in the pulp recovery mechanism is wet, and during vibration, it is difficult to significantly change the position of these debris, making them prone to getting stuck in the filter screen's pores, causing clogging and reducing the pulp recovery rate. This also carries the risk of pulp overflowing outside the filter screen. The mechanism includes a conical storage tank and a filter tube. The upper end of the conical storage tank is sealed with a sealing cover, and a feed hopper is fixedly installed at the upper end of the sealing cover. A feed pipe is fixedly installed at the lower end of the feed hopper. Through the cooperation between the filter tube and the U-shaped rod, the U-shaped rod scrapes the side wall of the filter tube when it rotates, effectively reducing the adhesion of pulp debris to the side wall of the filter tube.

Description

Technical Field

[0001] This utility model relates to the technical field of pulp recycling, specifically to a pulp recycling mechanism for a pulping machine. Background Technology

[0002] The sizing and grading machine is a combined piece of equipment used in the textile industry for warping and sizing processes. Its sizing material recycling mechanism can realize the recycling of sizing materials (such as starch, PVA, etc.), reducing production costs and environmental pollution.

[0003] A search revealed Chinese patent publication number CN218248881U, which discloses a pulping machine technology. The invention includes a fixed base with a fixed plate fixedly mounted on its upper surface. An integrated pulp storage tank is located inside the fixed plate. By placing the device directly below the pulping zone of the pulping machine, the falling pulp lands on the surface of a filter screen, filtering out impurities on the pulping surface. Then, a dual-axis motor in the vibration mechanism is activated. The two output shafts of the motor drive an elliptical movable block to rotate. This elliptical movable block, in conjunction with a rectangular limiting plate, drives a push rod to move vertically. The push rod, in conjunction with the fixed plate, moves the pulp storage tank vertically in the opposite direction, thus vibrating the pulp falling onto the filter screen. This prevents impurities on the pulping surface from preventing the pulp from passing through the filter screen, effectively avoiding impurities within the pulp.

[0004] However, the debris in the slurry recovery mechanism is wet, and it is difficult to make the position of these debris change significantly when the vibration device is working. This makes it easy for these debris to get stuck in the filter screen, causing the filter screen to become clogged, which reduces the slurry recovery rate and also carries the risk of slurry overflowing to the outside of the filter screen.

Detailed Implementation

[0015] 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.

[0016] Example 1 Please see Figure 1-4This utility model provides a pulp recovery mechanism for a pulping machine, including a conical storage tank 1 and a filter tube 17. A sealing cover 9 is sealed to the upper end of the conical storage tank 1. A feed hopper 13 is fixedly installed at the upper end of the sealing cover 9, and a feed pipe 14 is fixedly installed at the lower end of the feed hopper 13. The feed pipe 14 passes through the interior of the sealing cover 9 and extends to the lower end of the sealing cover 9. A toothed ring 15 is slidably sleeved on the outside of the feed pipe 14. The filter tube 17 is located at the lower end of the feed pipe 14. A connecting ring 16 is fixedly sleeved on the upper end of the filter tube 17, and a connecting ring 16 is fixedly installed on the lower end. The connecting plate 18 and connecting ring 16 are fastened to the toothed ring 15 by bolts, and the sidewalls of the connecting ring 16 and the toothed ring 15 are sealed by a sealing ring. The filter tube 17 is connected to the inside of the feed tube 14. A U-shaped rod 19 is fixedly installed at the bottom of the feed tube 14, and the sidewalls of the U-shaped rod 19 are all in contact with the inner sidewalls of the filter tube 17. A rotary motor 12 is fixedly installed at the upper end of the sealing cover 9, and an L-shaped plate 10 is fixedly installed at the bottom of the sealing cover 9. A gear 11 is rotatably connected between the L-shaped plate 10 and the sealing cover 9. The output shaft of the rotary motor 12 passes through the sealing cover. The inside of the cover 9 is fixedly connected to the upper end of the gear 11. The gear 11 meshes with the gear ring 15. The L-shaped plate 10 is set above the opening of the conical storage box 1. The lower end of the feed pipe 14 is provided with a support column 20, and the side walls of both ends of the U-shaped rod 19 are fixedly connected to the side walls of the support column 20. The lower end of the support ring 2 is provided with a support plate 3. The diameter of the support plate 3 is equal to the diameter of the support ring 2. Multiple connecting rods 21 are fixedly installed at equal intervals between the support plate 3 and the support ring 2. Universal wheels 4 are symmetrically fixedly installed at both ends of the bottom of the support plate 3. When the pulp from the pulping unit is being recycled, the recycling device moves to the lower end of the pulping unit, causing the hopper 13 to move to the lower end of the discharge port of the pulping unit, so that the pulp discharged from the pulping unit enters the interior of the feed hopper 13. At the same time, the rotary motor 12 is turned on, causing the gear 11 to rotate. The gear 11 drives the gear ring 15 to rotate, which can easily rotate the filter tube 17 at the lower end. When the filter tube 17 rotates, the side wall of the U-shaped rod 19 scrapes the inner side wall of the filter tube 17, which can effectively reduce the amount of debris in the pulp adhering to the inner side wall of the filter tube 17.

[0017] Example 2 To facilitate the installation and disassembly of the filter tube 17, in this embodiment, as follows: Figure 1-4As shown, the two ends of the sealing cover 9 extend to the outside of the two ends of the conical storage box 1. A support ring 2 is fixedly sleeved on the outside of the conical storage box 1. A cylinder 8 is symmetrically fixedly installed on the upper end of the support ring 2. The output shaft of the cylinder 8 is fixedly connected to the bottom side wall of the two ends of the sealing cover 9. A controller 7 is fixedly installed on the upper end of the support ring 2. The controller 7 is electrically connected to the cylinder 8. A discharge pipe 5 is fixedly connected to the lower end of the conical storage box 1. A valve 6 is fixedly installed inside the discharge pipe 5. When installing or removing the filter tube 17, the controller 7 opens the cylinder 8, causing the cylinder 8 to lift the sealing cover 9 upwards, so that the filter tube 17 is completely moved to the upper end of the conical storage box 1. Then, the bolts connecting the connecting ring 16 and the toothed ring 15 are removed, which allows the filter tube 17 to be easily removed and its interior to be thoroughly cleaned.

[0018] It should be noted that in this embodiment, when recovering the pulp from the pulping machine, the recovery device moves to the lower end of the pulping machine, causing the hopper 13 to move to the lower end of the pulping machine's discharge port, allowing the pulp discharged from the pulping machine to enter the interior of the feed hopper 13. The rotary motor 12 is electrically connected to the controller 7, and the controller 7 simultaneously turns on the rotary motor 12, causing the gear 11 to rotate. The gear 11 drives the gear ring 15 to rotate, facilitating the rotation of the lower filter tube 17. When the filter tube 17 rotates, the sidewall of the U-shaped rod 19 will impact the interior of the filter tube 17. Scraping the sidewalls effectively reduces the amount of debris in the slurry adhering to the inner sidewalls of the filter tube 17. After the slurry is recovered, opening valve 6 allows the slurry to be conveniently discharged through discharge pipe 5. When installing or removing the filter tube 17, the controller 7 opens cylinder 8, causing cylinder 8 to lift the sealing cover 9 upwards, so that the filter tube 17 is completely moved to the upper end of the conical storage box 1. Then, the bolts connecting the connecting ring 16 and the toothed ring 15 are removed, which allows the filter tube 17 to be easily removed and its interior to be thoroughly cleaned.
