Description

[Technical Field]

[0002] This utility model relates to the field of industrial dust treatment technology, and in particular to a dust-free treatment chamber for the wire drawing and polishing process of workpiece surfaces. [Background Technology]

[0004] Wire drawing and polishing are typical machining processes that generate serious dust pollution. The metal and abrasive dust produced poses various hazards to personnel health, equipment safety, and product quality. Currently, the mainstream technologies for treating this type of dust are mainly divided into two categories: dry dust collection and wet dust collection. However, both of these technologies have inherent and difficult-to-solve defects when applied to multi-station, open working environments.

[0005] To solve the above problems, the following processing methods are commonly used in the prior art:

[0006] The first approach is basic personal protective equipment and simple ventilation. This involves requiring workers to wear protective masks and installing exhaust fans on the workshop walls. However, this method only addresses the symptoms, not the root cause. Protective masks are ineffective at filtering nanoscale ultrafine particles, and exhaust fans merely transfer indoor pollution to the outside, causing secondary environmental pollution. Furthermore, they cannot create effective airflow to reduce the local dust concentration in the work area.

[0007] The second type uses a dry dust collection system with localized exhaust. This solution typically involves installing an adjustable dust hood at each workstation, and then using a duct system to draw dust-laden air to a baghouse or cartridge dust collector outside the workshop for filtration. However, for long, narrow workpieces or situations requiring mobile operation, the effective range of a single dust hood is limited, making it difficult to achieve complete, thorough dust collection. Furthermore, the filter cartridges of dry dust collectors require regular cleaning or replacement, making maintenance cumbersome and prone to generating secondary dust during replacement. Most importantly, concentrating a large amount of combustible metal dust in a dry, enclosed container (dust collector housing) significantly increases the risk of fire and explosion. [Utility Model Content]

[0009] The purpose of this invention is to provide a dust-free processing chamber for the wire drawing and polishing process of workpieces, aiming to solve the problems of low dust collection efficiency, dead corners in purification, and secondary pollution caused by the separation of operation and collection functions in the existing technology for multi-station, open working environments.

[0010] This utility model is achieved through the following technical solution:

[0011] A dust-free processing chamber for a workpiece surface wire drawing and polishing process includes a room body, a sedimentation platform in the middle of the room body, multiple equipment bodies for the wire drawing and polishing process arranged along the sedimentation platform, a water curtain wall structure communicating with the sedimentation platform on one side of the room body, multiple fans on the side wall of the water curtain wall structure facing the room body, the multiple fans being used to blow the waste dust generated during processing towards the water curtain wall structure, and a water circulation component for circulating water between the water curtain wall structure and the sedimentation platform.

[0012] As described above, the dust-free processing chamber for the wire drawing and polishing process of workpieces includes a water curtain wall structure comprising an arc-shaped flow guide wall located on one side of the chamber body, a water supply pipe located at the top of the arc-shaped flow guide wall, and a plurality of water outlet holes evenly distributed on the water supply pipe; a transition water trough located at the bottom of the arc-shaped flow guide wall, and a plurality of first through holes located on the inner wall of the transition water trough, the plurality of first through holes communicating with one side of the sedimentation platform.

[0013] In the dust-free treatment chamber for the wire drawing and polishing process of the workpiece surface as described above, the cross-section of the transition water tank is U-shaped.

[0014] As described above, in the dust-free processing chamber for the wire drawing and polishing process of workpieces, the sedimentation platform includes a sedimentation tank protruding from the ground, on which multiple metal grid plates are laid to support the main body of the equipment.

[0015] As described above, in the dust-free processing chamber for the wire drawing and polishing process of workpieces, a plurality of second through holes corresponding to the plurality of first through holes are provided on one side of the sedimentation tank, and a connecting channel is provided between each corresponding first through hole and second through hole.

[0016] In the dust-free processing chamber for the wire drawing and polishing process of the workpiece surface as described above, a plurality of pads are uniformly arranged between the metal grid and the bottom of the sedimentation tank.

[0017] As described above, in the dust-free processing chamber for the wire drawing and polishing process of workpieces, the sedimentation tank has a pipe groove at one end near the water circulation component. The water circulation component includes a circulating water pump. One end of the circulating water pump is connected to a water pumping pipe that extends into the sedimentation tank through the pipe groove. The other end of the circulating water pump is connected to a water delivery pipe, which is connected to the water supply pipe.

[0018] As described above, the dust-free treatment chamber for the workpiece surface wire drawing and polishing process has multiple maintenance slots at the upper edge of the sedimentation tank to facilitate the disassembly of the metal grid plate.

[0019] As described above, in the dust-free processing chamber for the wire drawing and polishing process of workpieces, water baffles are provided at both ends of the arc-shaped drainage wall.

[0020] The dust-free processing chamber for the wire drawing and polishing process of workpieces, as described above, has an arc-shaped drainage wall made of stainless steel plate.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. This utility model utilizes the synergistic effect of a sedimentation platform, a water curtain wall structure, and a fan to form a three-dimensional collection method of "blowing from above and falling from below." It not only captures suspended fine dust using the water curtain wall structure but also directly collects heavier particles and debris that settle due to gravity through the sedimentation platform. This solves the problems of separation between operation and collection functions and secondary pollution caused by heavy objects falling to the ground in existing technologies, and achieves comprehensive dust and debris collection.

[0023] 2. By installing multiple fans on opposite sides of the water curtain wall structure, a stable and uniform macroscopic directional airflow field is formed throughout the entire room. This airflow field can continuously and without dead angles push the diffused dust generated simultaneously by multiple workstations to the capture surface of the water curtain wall structure. Compared with existing technologies such as local dust collection hoods or simple rear exhaust, it has a wider airflow control range and higher dust collection efficiency.

[0024] 3. This utility model adopts the principle of wet dust removal, and the entire purification process is carried out in a water environment, which fundamentally eliminates the risk of fire or dust explosion that may occur when dry dust removal systems deal with combustible metal dust, and greatly improves the safety of operation.

[0025] 4. By setting up a water circulation component, the purified water is filtered and recycled, which significantly reduces water consumption and wastewater discharge, meets the requirements of modern industrial green production, and reduces the company's operating costs.

Detailed Implementation Methods

[0032] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0033] Please refer to the appendix. Figures 1 to 3 This embodiment discloses a dust-free processing chamber for a workpiece surface wire drawing and polishing process. Its basic structure includes a room body 1 defining an independent working space. In the central area of ​​the room body 1, a sedimentation platform 2 is arranged along its length. This sedimentation platform 2 serves as the core working area, on which multiple equipment bodies 3 for wire drawing, grinding, or polishing workpieces can be arranged staggered or side-by-side along its length. On one inner wall of the room body 1, such as the rear wall, a water curtain structure 4 is provided. The bottom of the water curtain structure 4 is interconnected with the interior of the sedimentation platform 2 to achieve water collection. On the inner wall opposite the water curtain structure 4, such as the front wall, multiple fans 5 are installed. These fans 5 are preferably oscillating axial flow fans, which can oscillate left and right during operation, thereby forming a dynamic airflow with a wide coverage area and no dead angles within the processing chamber, more efficiently blowing the dispersed dust generated simultaneously by multiple devices towards the water curtain structure 4 on the opposite side. In addition, this embodiment also includes a water circulation component 6, which establishes a closed-loop circulation between the water curtain wall structure 4 and the sedimentation platform 2, and is used to transport the water collected in the sedimentation platform 2 back to the top of the water curtain wall structure 4, so as to realize the recycling of water resources and the continuous operation of the system.

[0034] Furthermore, as a preferred embodiment, to maximize dust capture efficiency and ensure smooth water flow, the water curtain structure 4 mainly includes an arc-shaped drainage wall 41 vertically arranged along one inner wall of the room body 1. The arc-shaped drainage wall 41, viewed in cross-section, has a smooth, convex arc protruding towards the sedimentation platform 2. This design guides the water flow to fall closely against the wall in a laminar flow manner, forming a stable, splash-free, continuous water film, greatly improving the dust adsorption effect. At the top of the arc-shaped drainage wall 41, a water supply pipe 42 is horizontally fixed, with multiple rows of fine water outlets evenly distributed along its length, ensuring that circulating water is evenly distributed across the top of the entire arc-shaped drainage wall 41. At the two sides of the arc-shaped drainage wall 41, vertical baffles 45 are also provided to prevent water from splashing to both sides during its descent, ensuring that all water is effectively collected. In this embodiment, the arc-shaped drainage wall 41 is preferably made of stainless steel plate, due to its excellent corrosion resistance and smooth surface, making it less prone to dirt accumulation. However, those skilled in the art will understand that any other corrosion-resistant, smooth-surfaced material with similar properties, such as steel plates, aluminum alloy plates, or polymer material plates with special anti-corrosion treatment, can be used to implement this embodiment without departing from the spirit of this embodiment.

[0035] Furthermore, to achieve effective water collection and transition, a transition water trough 43 is integrally connected to the bottom of the arc-shaped drainage wall 41 to receive the water carrying dust flowing down from the wall. More specifically, the transition water trough 43 has a U-shaped cross-section to facilitate water collection. Multiple first through holes 44 are provided on the inner wall of the transition water trough 43, specifically on the side wall near the sedimentation platform 2. These first through holes 44 serve as outlets, allowing the water collected in the trough to flow smoothly into the sedimentation platform 2, which is connected to it.

[0036] Furthermore, the sedimentation platform 2 is designed as a multi-functional platform integrated with the ground structure. Specifically, it includes a sedimentation tank 21 integrally constructed of reinforced concrete or welded from thick steel plates. The top surface of the sedimentation tank 21 protrudes upwards from the original floor of the room 1 by a certain height, specifically 10-20 centimeters, forming a structure that serves as both a work platform and a sedimentation tank. At the upper opening of the sedimentation tank 21, multiple removable metal grids 22 are laid. These metal grids 22 possess sufficient strength and rigidity to stably support the weight of multiple equipment bodies 3 and vibrations during operation. Simultaneously, their grid structure allows waste liquid generated during processing, heavier metal particles, and dust clumps washed down by water to pass directly through and fall into the sedimentation tank 21 below. For ease of maintenance, multiple maintenance grooves 27 can be made at the upper edge of the sedimentation tank 21, corresponding to the seam or edge of the metal grid 22. These grooves provide leverage points for tools such as pry bars, making it easy to pry up and remove the metal grid 22 for cleaning of sediment.

[0037] Furthermore, to achieve reliable and efficient communication between the transition water tank 43 and the sedimentation tank 21, and to ensure the stable load-bearing capacity of the metal grid 22, multiple second through holes 23 are provided on the side wall of the sedimentation tank 21 near the water curtain structure 4, corresponding to the positions of the first through holes 44 on the transition water tank 43. A short connecting channel 24, such as a short pipe, is provided between each corresponding first through hole 44 and second through hole 23 via welding or flange connection, thereby firmly and sealingly connecting the two separate structures to ensure smooth water flow without leakage. In addition, multiple pads (not shown in the figure) are evenly distributed at the bottom of the sedimentation tank 21. These pads can be prefabricated cement blocks or metal blocks, used to elevate the metal grid 22 from the bottom of the tank, providing uniform and stable support for the metal grid 22 and preventing deformation due to long-term load.

[0038] Furthermore, as a key component for achieving water resource recycling, the water circulation component 6 in this embodiment adopts an external design for easy maintenance. Specifically, a pipe groove 26 is reserved near one end of the wall of the sedimentation tank 21. The water circulation component 6 mainly includes a circulating water pump 61, preferably a self-priming centrifugal pump, which is installed on the ground outside the sedimentation platform 2. One end of the pump is connected to a pumping pipe 62, which extends into the interior of the sedimentation tank 21 through the pipe groove 26. Its end is equipped with a filter screen and a one-way bottom valve. The other end of the pump 61, i.e., the outlet, is connected to a water supply pipe 63, which extends upward along the wall and finally reliably connects to the water supply pipe 42 at the top of the water curtain wall structure 4. When the circulating water pump 61 is working, it can extract the upper layer of clear water that has settled in the sedimentation tank 21 and pressurize and transport it to the top of the water curtain wall, thereby realizing a closed-loop circulation of the entire system.

[0039] In summary, the workflow of this embodiment is as follows: Fan 5 and water circulation component 6 are activated. Fan 5 begins to oscillate and deliver air, while circulating water forms a stable water curtain on the arc-shaped guide wall 41. The operator operates the equipment body 3 on the settling platform 2, which is covered with metal grids 22, to perform wire drawing and polishing of the workpiece. Dust generated during processing is blown towards the water curtain structure 4 by the wide dynamic airflow generated by fan 5 and is adsorbed and captured by the water curtain. The captured dust is carried by the water flow through the transition water tank 43 and connecting channel 24 into the settling tank 21 for sedimentation. Heavier particles and debris fall directly through the metal grids 22 into the settling tank 21. The water circulation component 6 continuously extracts the settled water from the tank and returns it to the top of the water curtain wall, repeating the cycle to achieve efficient and continuous dust-free treatment of the entire processing area.

[0040] Finally, as a supplementary explanation of the initial water supply and water level control method in this embodiment, an external water supply pipe (not shown in the figure) can be connected to a suitable location on the sedimentation tank 21. This water supply pipe is connected to the factory's water supply system. In an optional embodiment, a manual valve (not shown in the figure) is provided on this water supply pipe. Before the system is started for the first time, clean water can be injected into the sedimentation tank 21 by opening this manual valve until the water level reaches a preset working height, such as the water level line marked on the inner wall of the sedimentation tank 21, thereby completing the initial water injection of the system. During daily operation, the operator can also manually replenish the water supply caused by evaporation or sewage discharge through this valve.

[0041] As a more preferred automated implementation, the manual valve on the aforementioned water replenishment pipe can be replaced with a solenoid valve (not shown in the figure), and a level sensor (not shown in the figure), such as a float level switch, can be installed inside the sedimentation tank 21. This level sensor is linked to the solenoid valve for control. When the sensor detects that the water level in the tank has fallen below a preset lower limit due to water consumption, it automatically triggers a signal to open the solenoid valve for water replenishment; when the water level rises back to the preset upper limit, the sensor triggers a signal to close the solenoid valve, stopping water replenishment. This automated solution requires no manual intervention and ensures that the system water level remains stable within the optimal operating range, guaranteeing the safe and stable operation of the water circulation component 6.

[0042] The above are implementation methods provided in conjunction with specific content, and it is not intended that the specific implementation of this application is limited to these descriptions. Any methods or structures that are similar to those of this application, or any technical deductions or substitutions made based on the concept of this application, should be considered within the scope of protection of this application.
