Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, and more specifically to a papermaking pulp agent spraying device. Background Technology

[0002] In the modern papermaking industry, the quality of pulp directly determines the quality of the final paper product. Adding various agents to the pulp to improve its performance and meet the production requirements of different types of paper is a common and crucial step. These agents include, but are not limited to, wet-process paper strengthening agents, cleaning agents, resin control agents, anti-fouling agents, and release agents. They play an indispensable role in preventing foreign matter adhesion, improving wet paper web peel performance, and enhancing paper strength.

[0003] Currently, various pulp agent spraying devices exist on paper production lines. Some traditional devices use simple nozzle designs to directly spray the agents into the pulp tank. However, this approach has several problems in practical application:

[0004] If the equipment cannot flexibly adapt to changes in pulp level, the fixed-position nozzles cannot effectively spray pulp at different levels, resulting in poor mixing of the reagents in the pulp and limiting their ability to optimize pulp performance. Furthermore, the fixed spray angle cannot be adjusted according to the shape of the pulp tank, the state of pulp accumulation, and the mixing requirements of the reagents. Different types of pulp and different production processes have different reagent requirements, but traditional equipment can usually only spray reagents at a fixed flow rate and cannot be flexibly adjusted according to actual production needs. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a paper pulp agent spraying device to solve the problem that traditional spraying devices in the background art are difficult to flexibly adjust the height, spraying angle and spraying flow rate according to the actual situation, which affects the practicality.

[0008] Furthermore, the sidewalls of the liquid inlet end and the flow regulating end assembly are provided with annular grooves. The connecting mechanism includes a collar with a through hole at the top of the collar extending into the inner cavity. A nut is fixedly connected in the through hole, and a screw is threaded into the inner cavity of the nut. The collar rotates within the annular groove.

[0009] Furthermore, the lifting device includes an electric cylinder, which is fixedly installed on the inner wall of the mounting plate. The output end of the electric cylinder is connected to a connecting rod via a connecting block, and the bottom end of the connecting rod is fixedly connected to the top of the sliding arm.

Detailed Implementation

[0021] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Reference Figure 1This utility model provides a paper pulp agent spraying device, including a spray pipe 1 and two height adjustment mounting bracket assemblies 5. The side wall of the spray pipe 1 has several liquid outlets communicating with the interior. Each of the liquid outlets is fixedly installed with a nozzle 2. The two ends of the spray pipe 1 are respectively fixedly installed with a liquid inlet end 3 and a flow adjustment end assembly 4. The output ends of the two height adjustment mounting bracket assemblies 5 are respectively connected to the side walls of the liquid inlet end 3 and the flow adjustment end assembly 4. The output end of the flow adjustment end assembly 4 extends into the interior of the spray pipe 1 to adjust the diameter of the several liquid outlets of the spray pipe 1.

[0023] During use, the agent can be introduced into the spray pipe 1 through the inlet end 3. The agent inside the spray pipe 1 passes through several outlets and is sprayed through several nozzles 2. The diameter of the outlets of the spray pipe 1 can be adjusted by operating the flow adjustment end assembly 4, thereby controlling the flow rate of the agent through the outlets and achieving the effect of controlling the spray volume. The spray pipe 1 can be installed on the side wall of the pulp tank through two height adjustment mounting bracket assemblies 5. The height of the spray pipe 1 can be adjusted by outputting the two height adjustment mounting bracket assemblies 5 to adapt to the pulp liquid level.

[0024] Reference Figure 2 The height adjustment mounting bracket assembly 5 includes a mounting plate 51. A vertical groove 52 is provided on the side wall of the mounting plate 51. A sliding arm 53 is slidably sleeved in the vertical groove 52. A connecting mechanism 54 is fixedly connected to one end of the sliding arm 53. A lifting device is installed on the inner wall of the mounting plate 51. The output end of the lifting device is connected to the sliding arm 53. The connecting mechanisms 54 of the two height adjustment mounting bracket assemblies 5 are respectively connected to the liquid inlet end 3 and the flow adjustment end assembly 4.

[0025] In use, the lifting device drives the sliding arm 53 to slide vertically in the vertical slide groove 52. Since the connection mechanism 54 of the two height adjustment mounting bracket assemblies 5 are respectively connected to the liquid inlet end 3 and the flow adjustment end assembly 4, the height of the spray pipe 1 can be adjusted through the connection relationship between the spray pipe 1 and the liquid inlet end 3 and the flow adjustment end assembly 4.

[0026] Reference Figure 3 The sidewalls of the liquid inlet end 3 and the flow regulating end assembly 4 are provided with annular grooves. The connecting mechanism 54 includes a collar 541. The top of the collar 541 has a through hole that extends into the inner cavity. A nut 542 is fixedly connected in the through hole. A screw 543 is threaded into the inner cavity of the nut 542. The collar 541 rotates and is sleeved in the annular groove.

[0027] By adjusting the structure and shape of the connecting mechanism 54, it can prevent the inlet end 3 or the flow adjustment end assembly 4 from rotating. Thus, the spray pipe 1 can be rotated by turning it, thereby adjusting the spray angle of the nozzle 2. By rotating the screw 543, it can tighten the inner wall of the annular groove of the inlet end 3 or the flow adjustment end assembly 4, thereby fixing the angle.

[0028] Reference Figure 2 The lifting device includes an electric cylinder 55, which is fixedly installed on the inner wall of the mounting plate 51. The output end of the electric cylinder 55 is connected to a connecting rod 57 through a connecting block 56. The bottom end of the connecting rod 57 is fixedly connected to the top of the sliding arm 53.

[0029] When in use, the output of the electric cylinder 55 can raise or lower the connecting block 56. Under the connection effect of the connecting rod 57, the sliding arm 53 can be driven to rise or fall, thereby achieving the effect of controlling the raising and lowering of the sliding arm 53. Its lifting device can also be replaced by a threaded displacement structure.

[0030] Reference Figure 4 The flow control end assembly 4 includes an end block 41 and a slide rail 43. The end block 41 is fixedly connected to one end of the spray pipe 1. A push-pull mechanism 42 is provided inside the end block 41. The inner wall of the slide rail 43 is fixedly connected to the inner wall of the spray pipe 1. A baffle 44 is movably connected to the slide rail 43. The front of the baffle 44 is in contact with the inner wall of the spray pipe 1. Several liquid inlets 45 are opened on the front of the baffle 44. The number of liquid inlets 45 is equal to the number and diameter of several liquid outlets of the spray pipe 1. The output end of the push-pull mechanism 42 is fixedly connected to the back of the baffle 44.

[0031] In use, the push-pull mechanism 42 drives the baffle 44 to slide on the slide rail 43. In the initial state, the liquid inlet 45 overlaps with the liquid outlet of the spray pipe 1, and the liquid flow rate is at its maximum. After the baffle 44 slides, the electric cylinder 55 is misaligned with the liquid outlet. At this time, the baffle 44 can partially block the liquid outlet, thereby reducing the diameter of the liquid outlet and controlling the liquid flow rate.

[0032] Reference Figure 5 The push-pull mechanism 42 includes an L-shaped connector 421, a threaded shaft 422, and a motor 423. The L-shaped connector 421 is slidably sleeved inside the end block 41. One end of the L-shaped connector 421 has a threaded hole, and the other end is fixedly connected to the back of the baffle 44. The threaded shaft 422 is rotatably sleeved inside the end block 41. The threaded shaft 422 is threaded in the threaded hole at one end of the L-shaped connector 421. The motor 423 is fixedly installed on one side of the end block 41, and the output end of the motor 423 is fixedly connected to one end of the threaded shaft 422.

[0033] In use, the output of motor 423 drives the threaded shaft 422 to rotate. With the L-shaped connection 421 and the threaded shaft 422 in threaded engagement, the L-shaped connection 421 can be displaced, thereby achieving the sliding effect of the baffle 44.

[0034] Reference Figure 5 The L-shaped connector 421 has a fixed plate 424 fixedly connected to its side wall. One side of the fixed plate 424 is fixedly connected to the other side of the end block 41 through a corrugated telescopic tube 425.

[0035] This design prevents liquid inside the spray pipe 1 from leaking through the end block 41, where the corrugated expansion tube 425 acts as a liquid barrier.
