Description

Technical Field

[0001] This utility model relates to the technical field of papermaking dry wire cleaning equipment, and in particular to a dry wire spray cleaning device. Background Technology

[0002] In today's environment of soaring costs, energy conservation and emission reduction are of paramount importance to the paper industry, and increasing the recycling rate of waste paper effectively addresses this challenge. When paper is made from waste paper, the pulp always contains impurities such as sizing agents and waxes. These impurities on the paper surface sometimes adhere to the dry wire when in contact with it. Additionally, waste paper pulp often contains many short fibers, which easily detach and stick to the dry wire. This dirt accumulates gradually, eventually falling off the dry wire and sticking back to the paper, forming dirt spots. Furthermore, a dirty dry wire affects the heat transfer efficiency of steam drying. Therefore, a dry wire spray cleaning device is needed for regular cleaning. However, most existing dry wire spray cleaning devices have fixed spray heads that cannot move back and forth, resulting in poor cleaning effectiveness and failing to meet current needs. Utility Model Content

[0010] In one possible implementation, the spray unit includes a connecting box and a spray pipe;

[0011] The connecting box is fixed to the top of the transmission chain, and the spray pipe is installed on one side of the connecting box with the spray nozzle facing downwards.

The mixer is connected to the connection box via a pipeline.

[0016] In one possible implementation, a filter and a meter are also installed on the pipeline between the detergent storage tank and the connection box.

[0017] In one possible implementation, the number of spray units is several, and the several spray units are arranged at intervals along the outer surface of the transmission chain.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0029] use Figure 1 This paper describes a dry net spray cleaning device. Figure 1 This is a schematic diagram of the structure of the present invention. The dry net spray cleaning device includes a support beam 1, a transmission chain 2, a chain drive unit 3, a spray unit 4, a sensor assembly, and a controller, wherein:

[0030] The support beam 1 has a mounting groove on its outer side for mounting the transmission chain 2. The transmission chain 2 is installed into the mounting groove, that is, the support beam 1 can rotate around the outer side along its length to mount the transmission chain 2.

[0031] Transmission wheels 12 are rotatably mounted on both ends of the support beam 1. Transmission chain 2 is rotatably mounted on the transmission wheels 12. One end of the transmission chain 2 is connected to a chain drive unit 3, which is a drive motor. The chain drive unit 3 is mounted on one of the transmission wheels 12 and is used to drive the transmission chain 2 to rotate.

[0032] The spray unit 4 can be installed on the transmission chain 2. When the chain drive unit 3 drives the transmission wheel 12 to rotate, the transmission chain 2 can rotate on the support beam 1. That is, the spray unit 4 can rotate together with the transmission chain 2, so that the spray unit 4 can move and spray together with the transmission chain 2, thus realizing the purpose of the spray unit 4 to move and spray the dry net 100.

[0033] The sensor assembly includes a sensor 5 and a sensor connector 6. The sensor 5 is mounted on the side of the support beam 1, and the sensor connector 6 is mounted on the bottom of the spray unit 4. The positions of the sensor 5 and the sensor connector 6 are matched so that the sensor connector 6 can come into contact with the sensor 5 as the spray unit 4 rotates and moves.

[0034] The controller is electrically connected to the chain drive unit 3, the sensor 5, and the sensor connector 6. When the spray unit 4 moves, the sensor 5 and the sensor connector 6 can come into contact together to provide feedback to the controller. The controller then controls the chain drive unit 3 to rotate in both directions to achieve the reciprocating spraying of the spray unit 4.

[0035] In this embodiment, through the coordinated arrangement of support beam 1, transmission chain 2, chain drive unit 3, spray unit 4 and sensor assembly, when the spray unit 4 moves, sensor 5 and sensor connector 6 can come into contact. When sensor connector 6 and sensor 5 come into contact, sensor 5 can output a feedback signal to controller. When the controller receives the feedback signal output by sensor 5, the controller can control chain drive unit 3 to rotate in the opposite direction. This process is repeated. Whenever sensor connector 6 and sensor 5 come into contact, the controller can control chain drive unit 3 to rotate in the opposite direction, thereby achieving the purpose of reciprocating spraying of spray unit 4 and improving the cleaning effect of dry net 100.

[0036] Furthermore, since the dry wire 100 is composed of interwoven warp and weft threads, the water-based dry wire cleaner sprayed onto its surface coats both warp and weft threads, forming a thin insulating layer. This prevents dirt detached from the paper from adhering to the dry wire 100 surface, thus ensuring its cleanliness. After these treatments, the dry wire 100 remains clean, resulting in good air permeability, improved drying efficiency, and steam savings. Simultaneously, a cleaner dry wire 100 leads to a cleaner paper surface, improving the final paper quality.

[0037] In some embodiments, such as Figure 1 As shown. The spray unit 4 includes a connecting box 401 and a spray pipe 402. The connecting box 401 is fixed to the top of the transmission chain 2. The spray pipe 402 is installed on one side of the connecting box 401 with the spray nozzle facing downward. In order to increase the spray area of ​​the spray pipe 402, the spray nozzle of the spray pipe 402 is provided with a fan-shaped nozzle. The fan-shaped nozzle can spray a wider area at once, and can spray medicine on the surface of the dry net 100 in a short time and a large area.

[0038] In some embodiments, such as Figure 1 As shown. The dry net spray cleaning device also includes a cleaning agent storage tank 7, a compressed air supply device 8, and a mixer 9;

[0039] The cleaning agent storage tank 7 is connected to the connecting box 401 via a water pump pipeline. Specifically, the compressed air supply device 8 can be a compressor, and its supply end is connected to the mixer 9 via a pipeline. The cleaning agent storage tank 7 is connected to the mixer 9 via a water pump pipeline to achieve mixing of high-pressure gas and cleaning liquid within the mixer 9. The mixer 9 is connected to the connecting box 401 via a pipeline. In this embodiment, after the high-pressure gas and cleaning liquid are mixed in the mixer 9, they can be sprayed out through the connecting box 401 and the fan-shaped nozzle. Pressurization improves the spraying effect.

[0040] In some embodiments, such as Figure 1 As shown. A filter 10 and a meter 11 are also installed on the pipeline between the cleaning agent storage tank 7 and the connecting box 401. In this embodiment, the filter 10 can filter the cleaning liquid in the cleaning agent storage tank 7, and the filtered cleaning liquid can be metered by the meter 11 to prevent excessive cleaning liquid from entering the mixer 9.

[0041] In some embodiments, such as Figure 1 As shown. In order to further improve the spraying effect and spraying efficiency, there are several spraying units 4, which are arranged at intervals along the outer surface of the transmission chain 2, and each spraying unit 4 is equipped with a corresponding sensor component.
