Description

Technical Field

[0001] This utility model relates to the field of paper production technology, and in particular to a hammer-type pulp viscosity adjustment device. Background Technology

[0002] In the papermaking industry, pulp viscosity is one of the key parameters affecting paper quality. Excessive pulp viscosity can lead to decreased paper softness, reduced air permeability, and even cracks and tears during the drying process; conversely, insufficient pulp viscosity will result in insufficient paper strength, affecting its performance. Therefore, precisely adjusting pulp viscosity is crucial for producing high-quality paper.

[0003] Existing technology for measuring the viscosity of pulp typically uses a capillary viscometer. Before measurement, a suitable solvent must be selected to dissolve the cellulose material, and then the viscosity of the resulting cellulose solution is measured. This process is very cumbersome, costly, and has low detection efficiency.

[0004] An existing patent (publication number: CN220003615U) discloses a pulp viscosity regulator, including a conveying pipe and an adjusting mechanism. The adjusting mechanism is installed on the surface of the conveying pipe and includes an inlet pipe, a discharge pipe, a mounting base, a connecting pipe, a discharge pipe, a paddle, a speed sensor, a water inlet pipe, and a solenoid valve. The inlet pipe is installed near the pulp input end of the conveying pipe, and the discharge pipe is installed at the end of the conveying pipe. During conveying, some pulp enters the mounting base through the connecting pipe and drives the paddle to rotate during the descent. If the pulp viscosity is low, the descent rate is fast, driving the paddle to rotate at high speed. If the pulp viscosity is high, the descent rate is slow, and the paddle speed is low. The speed sensor monitors the change in paddle speed to monitor the pulp viscosity, and the real-time monitoring data drives the control of the water flow of the terminal water supply equipment to adjust the pulp viscosity. The structure is simple, the installation and use cost is low, and it can realize automatic monitoring and adjustment of pulp viscosity.

[0005] Existing patents offer solutions to the aforementioned problems, but they cannot automatically deliver liquid into the conveying pipe based on the pulp viscosity, nor can they automatically adjust the pulp viscosity.

[0006] To address this, a weighted pulp viscosity adjustment device is proposed. Utility Model Content

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.

[0029] Please see Figures 1 to 5 This utility model provides a technical solution:

[0030] A weighted pulp viscosity adjustment device includes a conveying pipe 1, a feeding pipe 2 at one end of the conveying pipe 1, a connecting pipe 3 at the bottom of the feeding pipe 2, a feeding pipe 4 at the other end of the conveying pipe 1, an adjustment mechanism 5 in the middle of the feeding pipe 2, and a liquid inlet control mechanism 6 at one end of the conveying pipe 1.

[0031] The adjusting mechanism 5 includes a sliding frame 51 movably disposed inside the feeding pipe 2. An adjusting hopper 52 is provided at the bottom of the sliding frame 51. A sliding groove 53 is provided on the side wall of the feeding pipe 2. A sliding block 54 is fixedly connected to the side wall of the sliding frame 51. An adjusting rod 55 is fixedly connected to the side wall of the two sliding blocks 54. A connecting seat 56 is provided at the bottom of the conveying pipe 1. The connecting seat 56 is hinged to the adjusting rod 55. A hammer body 57 is provided at one end of the adjusting rod 55. An adjusting component 58 is provided between the adjusting rod 55 and the hammer body 57.

[0032] Specifically, such as Figure 3As shown, the adjustment assembly 58 includes a slide groove 581 disposed at one end of the adjustment rod 55, a slider 582 movably disposed inside the slide groove 581, an mounting plate 583 mounted at one end of the adjustment rod 55, an adjustment screw 584 disposed in the middle of the mounting plate 583, the adjustment screw 584 being threadedly connected to the slider 582, and the hammer body 57 being fixedly connected to the slider 582.

[0033] Specifically, such as Figure 3 As shown, end caps 7 are provided at both ends of the conveying pipe 1. A conveying shaft 8 is connected to the bearing in the middle of the end cap 7. A spiral blade 9 is fixedly connected to the side wall of the conveying shaft 8. A drive motor 10 is bolted to the side wall of the end cap 7. The output end of the drive motor 10 is fixedly connected to the conveying shaft 8.

[0034] Specifically, such as Figure 1 and Figure 3 As shown, an adjusting disc 11 is fixedly connected to the bottom of the connecting pipe 3. An adjusting shaft 12 is connected to the middle bearing of the adjusting disc 11. Three adjusting blades 13 are fixedly connected to the side wall of the adjusting shaft 12. Adjusting sleeves 14 are provided at both ends of the adjusting shaft 12. An adjusting column 15 is movably provided in the middle of the adjusting sleeve 14. Adjusting balls 16 are provided at both ends of the adjusting column 15. The adjusting sleeve 14 and the adjusting column 15 are bolted together. A discharge pipe 17 is provided at the bottom of the adjusting disc 11.

[0035] Specifically, such as Figure 3 As shown, multiple buffer heads 18 are fixedly connected to the top of the adjusting bucket 52. The buffer heads 18 are T-shaped and are movably connected to the connecting pipe 3. A mounting spring 19 is sleeved on the side wall of the buffer head 18.

[0036] Specifically, such as Figure 5 As shown, a sealing block 20 is provided on the side wall of the buffer head 18, and multiple sealing covers 21 are provided on the top of the connecting pipe 3. The sealing block 20 and the sealing cover 21 are movably connected.

[0037] In use, the conveying pipe 1 uses the spiral blade 9 to directionally convey the pulp. The drive motor 10 drives the conveying shaft 8 to provide driving force for the spiral blade 9. The raw material is conveyed to the discharge pipe 2 through the feed pipe 4. The pulp falls into the connecting pipe 3 under its own weight. The pulp squeezes the regulating hopper 52. During this process, the regulating hopper 52 drives the sliding block 54 to move downward inside the sliding groove 53. At this time, the buffer head 18 squeezes and contracts the mounting spring 19. The pulp falls through the gap between the regulating hopper 52 and the connecting pipe. During this process, one end of the regulating rod 55 falls, and due to the action of the connecting seat 56, the other end of the regulating rod 55 moves upward, opening the liquid inlet control mechanism 6 and allowing external liquid to enter the conveying pipe 1. Depending on the viscosity of the pulp, when the pulp viscosity is high and the fluidity of the pulp is low, the regulating hopper 52 moves downward over a large range. The liquid inlet control mechanism 6 increases the liquid delivery volume. When the pulp flowability is suitable, the spring 19 supports the adjustment mechanism, causing one end of the adjusting rod 55 to separate from the liquid inlet control mechanism 6. The liquid inlet control mechanism 6 is in the closed state. By rotating the adjusting screw 584, the slider 582 is driven to move inside the slide groove 581, so that the hammer 57 is located at different positions of the adjusting rod 55. This allows the adjusting rod 55 to be adjusted to meet the needs of pulps with different viscosities. When the pulp falls into the adjusting plate 11, due to the flowability of the pulp, the adjusting shaft 12 and the adjusting blade 13 are driven to rotate. At this time, the adjusting sleeve 14 at one end of the adjusting shaft 12 drives the adjusting column 15 to rotate. By adjusting the different positions of the adjusting rod 55 inside the adjusting sleeve 14, the rotation speed of the adjusting column 15 is adjusted, thereby adjusting the pulp delivery speed.

[0038] Specifically, such as Figure 4 As shown, the liquid inlet control mechanism 6 includes a control pipe 61 installed at the bottom of the delivery pipe 1, a liquid inlet pipe 62 provided in the middle of the control pipe 61, one end of the liquid inlet pipe 62 being connected through the delivery pipe 1, a bottom cover 63 provided at the bottom of the control pipe 61, a T-shaped block 64 movably provided in the middle of the bottom cover 63, a support spring 65 sleeved in the middle of the T-shaped block 64, the support spring 65 being located between the bottom cover 63 and the T-shaped block 64, and a block block 66 fixedly connected to the top of the T-shaped block 64.

[0039] Specifically, such as Figure 4 As shown, a rubber head 22 is provided at the bottom of the T-block 64.

[0040] In use, during pulp feeding and conveying, the impact of pulp of different viscosities on the regulating hopper 52 causes the regulating rod 55 to move to different ranges. One end of the regulating rod 55 will strike the T-block 64. During this process, the support spring 65 supports the T-block 64. When the T-block moves, it drives the blocking block 66 to move inside the control tube 61. In the initial state, the blocking block 66 blocks the inlet pipe 62. When the regulating rod 55 moves to different ranges, it drives the T-block 64 to drive the blocking block 66 to move to different ranges inside the regulating rod 55, thereby adjusting the inlet flow rate of the inlet pipe 62 and realizing the automatic adjustment of the pulp viscosity.

[0041] By adopting the above technical solution, the problem that existing pulp viscosity regulators cannot automatically deliver liquid into the conveying pipe 1 according to the pulp viscosity, and cannot automatically adjust the pulp viscosity, is solved.

[0042] Working principle: In use, the conveying pipe 1 firstly achieves directional conveying of pulp through the spiral blade 9. The drive motor 10 drives the conveying shaft 8 to provide driving force for the spiral blade 9. The raw material is conveyed to the discharge pipe 2 through the feed pipe 4. The pulp falls into the connecting pipe 3 by its own gravity. The pulp squeezes the regulating hopper 52. During this process, the regulating hopper 52 drives the sliding block 54 to move downward inside the sliding groove 53. At this time, the buffer head 18 squeezes and contracts the mounting spring 19. The pulp falls from the gap between the regulating hopper 52 and the connecting pipe. During this process, due to the regulating rod 55... As the end of the tube falls, the other end of the adjusting rod 55 moves upward due to the action of the connecting seat 56. One end of the adjusting rod 55 will hit the T-block 64. During this process, the support spring 65 supports the T-block 64. When the T-frame moves, it drives the blocking block 66 to move inside the control tube 61. In the initial state, the blocking block 66 blocks the liquid inlet pipe 62. When the adjusting rod 55 moves to different ranges, it drives the T-block 64 to drive the blocking block 66 to move to different ranges inside the adjusting rod 55, thereby adjusting the liquid inlet flow rate of the liquid inlet pipe 62 and realizing the automatic adjustment of the pulp viscosity.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
