Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically relating to a paper machine forming wire cleaning device. Background Technology

[0002] In papermaking, the forming wire (also known as the papermaking wire) is a critical consumable component. Its function is to remove moisture from the paper stock during the paper forming process. During continuous operation, the forming wire mesh is easily clogged by fine pulp fibers, sizing agents, fillers, and other contaminants, leading to decreased permeability, affecting paper quality, increasing energy consumption, and shortening the forming wire's lifespan. Therefore, regular cleaning of the forming wire is necessary.

[0003] In the existing technology, the cleaning of forming wires is mostly done by manual rinsing with high-pressure water guns or simple fixed spray devices. Manual rinsing is inefficient, the cleaning effect is unstable, and water resources are wasted. Although simple fixed spray devices achieve a certain degree of automation, their cleaning power is limited and they are not effective in removing stubborn blockages. Therefore, we propose a paper machine forming wire cleaning device. Utility Model Content

[0004] To address the issues raised in the prior art, the cleaning of forming wires in the aforementioned background section primarily relies on manual rinsing with high-pressure water guns or simple fixed spray devices. Manual rinsing is inefficient, produces inconsistent cleaning results, and wastes significant water resources. While simple fixed spray devices offer some automation, their cleaning power is limited, and they are ineffective at removing stubborn blockages. This invention provides a paper machine forming wire cleaning device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper machine forming wire cleaning device, comprising a support frame, a forming wire body, and a cleaning brush. Drive rollers are rotatably mounted on both sides of the upper part of the support frame. The forming wire body is sleeved on the drive rollers. Fixed rods are fixedly connected to both ends of the drive rollers. A fixed plate is fixedly connected between the fixed rods on both sides. Sleeves are fixed to both the upper and lower ends of the fixed plates. A hydraulic telescopic rod is installed inside the sleeves. A telescopic plate is connected to the piston rod end of the hydraulic telescopic rod. A cleaning brush is fixedly installed on the end of the telescopic plate opposite to the hydraulic telescopic rod.

[0006] A water storage tank is provided above one end of the support frame, and a water pump is connected to the water storage tank. The water pump is connected to a cleaning nozzle through a pipe, and a collection box is provided at the bottom inner side of the support frame.

[0007] As a preferred embodiment of the paper machine forming wire cleaning equipment of this utility model, one end of one of the drive rollers is connected to a drive motor for driving its rotation.

[0008] In a preferred embodiment of the paper machine forming wire cleaning equipment of this utility model, the hydraulic telescopic rod forms a telescopic structure between the telescopic plate and the cleaning brush, and the cleaning brush is used to scrape the forming wire body.

[0009] As a preferred embodiment of the paper machine forming wire cleaning equipment of this utility model, the collection box is used to collect cleaning wastewater, and an installation groove is provided at one end of the collection box.

[0010] As a preferred embodiment of the paper machine forming wire cleaning equipment of this utility model, a filter frame is detachably installed inside the collection box, and a filter assembly is provided below the filter frame.

[0011] As a preferred embodiment of the paper forming wire cleaning equipment of this utility model, the filter frame and the filter assembly are interlocked and connected, and the filter assembly is a multi-layer structure containing filter media of different particle sizes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a high-pressure spray system (water pump, cleaning nozzle) and a mechanical scraping system (hydraulic telescopic rod, cleaning brush, etc.) working in concert, the system first uses the impact force of water flow for preliminary rinsing, and then uses mechanical scraping for deep cleaning. The combination of the two can effectively remove various contaminants, from loose to stubborn, ensuring the thoroughness of the cleaning effect and significantly improving the cleaning efficiency. The scheme of using a hydraulic telescopic rod to drive the cleaning brush allows the contact pressure between the cleaning brush and the forming mesh body to be flexibly and precisely adjusted according to the actual working conditions, preventing the problems of low efficiency and unstable cleaning effect of manual rinsing methods, and the limited cleaning power of simple fixed spray devices.

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 scope of protection of the present utility model. Embodiment 1

[0021] like Figures 1-5 As shown;

[0022] A paper machine forming wire cleaning device includes a support frame 1, a forming wire body 3, and a cleaning brush 8. Drive rollers 2 are rotatably mounted on both sides of the upper part of the support frame 1. The forming wire body 3 is sleeved on the drive rollers 2. Fixed rods 4 are fixedly connected to both ends of the drive rollers 2. Fixed plates 5 are fixedly connected between the fixed rods 4 on both sides. Sleeves 6 are fixed to both the upper and lower ends of the fixed plates 5. A hydraulic telescopic rod 9 is installed inside the sleeves 6. A telescopic plate 7 is connected to the piston rod end of the hydraulic telescopic rod 9. The cleaning brush 8 is fixedly installed at the end of the telescopic plate 7 facing away from the hydraulic telescopic rod 9. A water storage tank 10 is provided above one end of the support frame 1. A water pump 11 is connected to the water storage tank 10. The water pump 11 is connected to a cleaning nozzle 12 via a pipe. A collection box 13 is provided at the bottom inner side of the support frame 1.

[0023] In this implementation scheme, by setting up a high-pressure spray system—water pump 11, cleaning nozzle 12 and a mechanical scraping system—hydraulic telescopic rod 9, cleaning brush 8, etc., the system first uses the impact force of water flow for preliminary rinsing, and then uses mechanical scraping for deep cleaning. The combination of the two can effectively remove various contaminants, from loose to stubborn, ensuring thorough cleaning and significantly improving cleaning efficiency. The scheme of using hydraulic telescopic rod 9 to drive cleaning brush 8 allows the contact pressure between cleaning brush 8 and the forming mesh body 3 to be flexibly and precisely adjusted according to actual working conditions such as the degree of contamination of the mesh surface and the age of the mesh. This ensures effective cleaning force while avoiding unnecessary damage to the forming mesh due to excessive pressure, thus extending the service life of the forming mesh.

[0024] In an optional embodiment, one end of one of the drive rollers 2 is connected to a drive motor for driving its rotation.

[0025] In this implementation scheme, the direct connection between the drive motor and the drive roller 2 ensures a stable output of the torque transmitted to the forming mesh body 3.

[0026] In an optional embodiment, the hydraulic telescopic rod 9 forms a telescopic structure between the telescopic plate 7 and the cleaning brush 8, which is used to scrape the shaped mesh body 3.

[0027] In this implementation scheme: the hydraulic telescopic rod 9 drives the cleaning brush 8 through the telescopic plate 7 to form a telescopic structure, which can adjust the contact pressure between the cleaning brush 8 and the forming mesh body 3 in real time to adapt to the cleaning needs of different levels of pollution.

[0028] In an optional embodiment, the collection tank 13 is used to collect cleaning wastewater, and an installation groove 14 is provided at one end of the collection tank 13.

[0029] In this implementation scheme: the collection box 13 is located directly below the forming mesh body 3 to ensure that wastewater is collected quickly and to prevent splashing and pollution of the equipment environment. The installation slot 14 provides a standardized installation interface for the filtration system, enabling the collection box 13 to have functional expansion capabilities and facilitating the subsequent installation of different types of filtration modules.

[0030] In an optional embodiment, a filter frame 15 is detachably installed inside the collection box 13, and a filter assembly 16 is disposed below the filter frame 15.

[0031] In this implementation scheme: the detachable design of the filter frame 15 allows operators to quickly remove it for cleaning or replacement without tools, greatly reducing equipment maintenance time and costs. The layered layout of the filter frame 15 and the filter assembly 16 provides physical space for multi-stage filtration, allowing for flexible configuration of filter media combinations according to water quality requirements.

[0032] In an optional embodiment, the filter frame 15 and the filter assembly 16 are interlocked, and the filter assembly 16 is a multi-layer structure containing filter media of different particle sizes.

[0033] In this implementation scheme: the multi-layer structure filter component 16 adopts a gradient particle size design, which can intercept pollutants of different particle sizes step by step.

[0034] Working principle:

[0035] The support frame 1 serves as the basic structure of the entire equipment. The drive rollers 2 installed on both sides above it are driven to rotate by the drive motor installed at one end. The forming wire body 3 is fitted on the drive rollers 2 and is continuously circulated and conveyed as the drive rollers 2 rotate, simulating its actual operating state on the paper production line. After the equipment is started, the cleaning liquid in the water storage tank 10 is pumped out by the water pump 11 and transported through the pipeline to the cleaning nozzle 12 located above the forming wire body 3. The cleaning nozzle 12 sprays the cleaning liquid evenly onto the surface of the forming wire body 3 in operation at a certain pressure, initially wetting the wire surface, and using the impact force of the water flow to peel off and wash away most of the loose contaminants such as pulp fibers and fillers.

[0036] During or after spray rinsing, the hydraulic telescopic rod 9 is activated, pushing the telescopic plate 7 and the cleaning brush 8 on it to move outward until the bristles of the cleaning brush 8 are in close contact with the surface of the forming mesh body 3 in operation. The continuous movement of the forming mesh body 3 combined with the scraping action of the cleaning brush 8 can effectively remove stubborn adhesives that are difficult to remove by high-pressure spraying, thoroughly clean the mesh, and restore the water permeability and surface flatness of the forming mesh.

[0037] Wastewater containing contaminants generated from rinsing and scraping drips downwards under gravity. The collection box 13 installed at the bottom of the inner side of the support frame 1 collects the wastewater. Below the filter frame 15 is a filter assembly 16 composed of multiple media, which can finely filter the wastewater flowing into the collection box 13 to remove solid particulate impurities in the water. The upper layer of quartz sand with a particle size of 0.8-1.2mm intercepts medium-sized particles, the middle layer of anthracite with a particle size of 0.5-0.8mm adsorbs fine suspended solids, and the lower layer of garnet with a particle size of 0.3-0.5mm achieves micron-level filtration. The relatively clean water after filtration can be guided back to the water storage tank 10 or directly pumped back into the cleaning nozzle 12 by the water pump 11 for recycling. The mounting groove 14 is used to detachably install the filter frame 15. The detachable design of the filter frame 15 and the filter assembly 16 facilitates regular cleaning or replacement of filter media to maintain filtration efficiency.

[0038] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
