Description

Technical Field

[0001] The utility model belongs to the field of papermaking, and in particular relates to a paper pulp agent spraying device for papermaking. Background Art

[0002] In the preparation process of kraft paper and tube paper, waste paper pulp is the main raw material. Waste paper can be processed by different methods to obtain fibrous materials, which can be divided into mechanical pulp, chemical pulp and chemical-mechanical pulp according to the processing method.

[0003] Based on the prior art, it is found that since pulp contains a large amount of fibers, when the agent is sprayed out through the existing spraying device, the spraying range of the agent is limited, and in the process of spraying the agent, the fibers in the pulp are very likely to block the agent, resulting in the inability to spray the agent evenly into the pulp pool, resulting in poor spraying effect of the agent, affecting the quality of the pulp;

[0004] For example, Chinese patent CN218810454U can rotate the central tank by starting the motor, and can spray the agent evenly in the sewage pool with the use of the nozzle, but it cannot adapt to pulp with different liquid levels and has poor practicality. Utility Model Content

[0005] In order to overcome the disadvantage that during the process of spraying the agent, fibers in the pulp can easily block the agent, resulting in the inability to spray the agent evenly into the pulp pool, the utility model provides a pulp agent spraying device for papermaking.

[0006] The technical solution adopted by the utility model is as follows:

[0008] Optionally, every two adjacent nozzles are staggered with each other up and down, and all nozzles at the same height are distributed in a circular shape with equal intervals, so as to spray the agent into the pulp.

[0009] Optionally, all the toggle plates are configured to be detachable to facilitate later maintenance and replacement.

[0010] Optionally, it also includes a connecting rod, a fixed cylinder, a joint II, an inner ring, a baffle, a partition and an airbag; at least two connecting rods are fixed to the lower surface of the circular ring; the lower ends of all the connecting rods are commonly fixed to a fixed cylinder, which has a plurality of through holes; two joints II are connected to the upper part of the fixed cylinder; the inner side of the fixed cylinder is fixed to the inner side of the fixed cylinder, which has a plurality of through holes; two baffles are equidistantly fixed to the inner side of the inner ring in an annular shape, and the inner side of the inner ring is divided into two chambers by the two baffles; four partitions are equidistantly fixed to the outer side of the inner ring in an annular shape, and all the partitions are fixed to the fixed cylinder, and the fixed cylinder and the inner ring are separated by all the partitions; an airbag is fixed to the outer side of the fixed cylinder, and the inner side of the airbag is divided into two chambers.

At the same time, all the toggle plates are used to rotate and toggle the pulp, so that the fibers in the pulp are away from the center of the ring, thereby effectively increasing the spraying range of the reagents. All the toggle plates are used to rotate and toggle the pulp, so that the pulp and the reagents are mixed, thereby improving the spraying effect of the reagents;

[0014] 2. The buoyancy generated by the airbag expansion will drive the partition, inner ring and baffle to move upward, and then the sleeve will move upward along the outer wall of the connecting rod, and then drive all the connected parts to move, and then all the nozzles will move upward, so that the nozzles can move in the pulp, so as to spray the agent on different liquid surfaces of the pulp;

[0015] 3.

[0024] Every two adjacent nozzles 32 are staggered with each other up and down, and all the nozzles 32 at the same height are distributed in a circular shape with equal distances, so as to spray the agent into the paper pulp.

[0025] All the toggle plates 204 are configured to be detachable for later maintenance and replacement.

[0026] It also includes a connecting rod 301, a fixing cylinder 302, a joint II 303, an inner ring 304, a baffle 3041, a partition 3042 and an airbag 305; two connecting rods 301 are fixedly connected to the lower surface of the ring 3; the lower ends of all the connecting rods 301 are commonly fixedly connected to a fixing cylinder 302, and a plurality of through holes are opened on the fixing cylinder 302; the upper part of the fixing cylinder 302 is fixedly connected and connected to two joints II 303; the inner side of the fixing cylinder 302 is fixedly connected to the inner ring 304, and a plurality of through holes are opened on the inner ring 304; through holes; two baffles 3041 are fixedly connected to the inner side of the inner ring 304 at equal intervals, and the inner side of the inner ring 304 is divided into two chambers by the two baffles 3041; four partitions 3042 are fixedly connected to the outer side of the inner ring 304 at equal intervals, and all the partitions 3042 are fixedly connected to the fixed cylinder 302, and the fixed cylinder 302 and the inner ring 304 are separated by all the partitions 3042; an airbag 305 is fixedly connected to the outer side of the fixed cylinder 302, and the inner side of the airbag 305 is divided into two chambers.

[0027] It also includes a cover shell 22; the lower part of the sliding sleeve 21 is fixedly connected to the cover shell 22, and the cover shell 22 is rotatably connected to the base 1. The cover shell 22 is made of wear-resistant rubber material and is used to cover the connection between the base 1 and the connecting rod 2 to prevent debris from getting stuck between the base 1 and the connecting rod 2.

[0028] When spraying pulp: the outer wall of the ring 3 is connected by an external longitudinal guide rail, so as to limit the position of the ring 3, so that the ring 3 remains stable when sliding up and down, and then the external pipeline for conveying the agent is connected to the joint Ⅰ31, so that the agent can flow into the ring 3 through the joint Ⅰ31, and then the external air pump for air delivery is connected to the two joints Ⅱ303, and then the base 1 is fixed in the middle of the pulp pool by bolts. When it is necessary to spray the pulp agent, the agent is conveyed to the joint Ⅰ31 through the external pipeline, and when the agent enters the ring 3, it is sprayed out from the multiple nozzles 32, so as to realize the spraying of the agent on the pulp;

[0029] Since the pulp contains a large amount of fiber, when the agent is sprayed through multiple nozzles 32, the spraying range of the agent is limited, resulting in the agent being easily sprayed in the pulp near the ring 3, and in the process of spraying the agent, the fiber in the pulp is very likely to block the agent, resulting in the inability to spray the agent evenly into the pulp pool, resulting in poor spraying effect of the agent, affecting the quality of the pulp, and controlling the motor 202 to start, the output shaft of the motor 202 rotates to drive the connecting rod 2 to rotate, the connecting rod 2 rotates to drive the sliding sleeve 21 to rotate, and the sliding sleeve 21 rotates. The rotation drives all the toggle plates 204 to rotate, and then all the toggle plates 204 rotate and toggle the pulp, so as to avoid the problem that the fibers in the pulp block the agent, resulting in the inability to spray the agent evenly into the pulp pool. At the same time, all the toggle plates 204 rotate and toggle the pulp, so that the fibers in the pulp are away from the center position of the ring 3, thereby effectively improving the spraying range of the agent, and all the toggle plates 204 rotate and toggle the pulp, so that the pulp and the agent are mixed, thereby improving the spraying effect of the agent;

[0030] The initial state of the airbag 305 is an uninflated state. When all the nozzles 32 are spraying the medicine, the external pump is controlled to operate to inflate the fixed cylinder 302 through the two joints II 303, so that the gas enters the airbag 305 through the through hole of the fixed cylinder 302, and the airbag 305 expands. When the airbag 305 expands, the buoyancy generated by the airbag 305 will drive the partition 3042, the inner ring 304 and the baffle 3041 to move upward, so that the sliding sleeve 21 moves upward along the outer wall of the connecting rod 2, and then drives all the connected parts to move, so that all the nozzles 32 move upward, so that the nozzles 32 move in the pulp, so as to spray the medicine on different liquid levels of the pulp;

[0031] Moreover, in order to further improve the spraying effect of the agent and make the pulp and the agent mix more evenly, when the airbag 305 moves upward, the toggle plate 204 on the sleeve 21 will also move upward synchronously. At this time, the pulp is rotated and toggled by the toggle plate 204 according to the same working principle as above, so that the pulp and the agent are mixed, thereby further improving the spraying effect of the agent. Compared with the prior art, all nozzles 32 and all toggle plates 204 are moved up and down by the buoyancy generated by the airbag 305, which makes it simpler and more portable to spray the agent on different liquid level heights of the pulp, thereby making the mixture of the agent and the pulp more even and facilitating later maintenance.
