Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dust removal technology, specifically relating to a hybrid dust removal and treatment system. Background Technology
[0002] Currently, for dust control in spaces such as machinery manufacturing workshops with large spans, high buildings, numerous welding stations, and scattered layouts, the traditional method of capturing and collecting dust at individual points cannot completely and effectively capture the fumes at some points because robots enter and exit the workstations, or because the fumes from the workpieces are moved to the next workstation before they are completely collected. This results in some fumes overflowing and spreading in the workshop air, affecting the production environment and worker operations.
[0003] Furthermore, welding points are generally on the ground. The fumes generated during welding are suspended and concentrated in the workshop air under the influence of heat. If a comprehensive treatment and collection system is adopted, the required air volume will be large, which will increase the initial investment cost and the operation and maintenance costs during use.
[0004] Furthermore, regarding overall governance, if a full internal circulation system is adopted, the large amount of heat generated in the workshop during the summer will be discharged indoors through internal circulation, causing the workshop temperature to rise continuously. This will not only affect the workers' operating environment but also lead to a continuous increase in indoor dust concentration. If a full fresh air system is adopted, the workshop's heat energy will be discharged outdoors in winter, which will easily cause energy loss and lead to a continuous decrease in indoor ambient temperature, which is not conducive to a dual-carbon economy.

[0037] Furthermore, the air supply duct is located at position 5 of the factory building's pillars.

The sliding suction trolley is installed on the sliding air duct and moves along the sliding air duct. The dust collector C is installed on the factory floor.
[0044] The work process is as follows:
[0045] Localized workspace management systems: such as Figure 5 and Figure 6 As shown, for larger workpieces, the process method in workshop 1-1 (robotic welding, manual welding repair, manual grinding, etc.) is adopted. The dust-generating point is completely enclosed by an electric lifting door 1-2 to prevent dust overflow and noise diffusion. The dust is collected through a suction hood A1-3 and sent to a dust collector A1-6 for purification through a pipeline A1-5. The dust is then discharged indoors or outdoors as needed. Each point can be individually controlled by an electric valve A1-4 according to the on-site usage.
[0046] Localized fixed suction hood treatment system: such as Figure 7 and Figure 8 As shown, for manufacturing and processing locations that are relatively fixed, a fixed suction hood is used to enclose the dust-generating points. Curtains are hung around the perimeter to prevent dust and fumes from escaping. Dust and fumes are collected through suction hood B2-2 and transported to dust collector B2-5 via pipe B2-4 for purification. Discharge is then carried out indoors or outdoors as needed. Each point can be individually controlled via an electric damper B2-3, depending on the site conditions.
[0047] Localized mobile suction hood treatment system: such as Figure 9 , Figure 10 and Figure 11 As shown, for situations where the workpiece is large or long, the manufacturing and processing area is large, and the processing machine needs to be moved for operation, a mobile suction hood is used to enclose the robot's dust-generating points. The suction hood C3-2 is fixedly connected to the processing machine and moves with it. Curtains are hung around the suction hood C3-2 to prevent dust and fumes from escaping. The suction hood C3-2 collects dust and sends it through pipe C3-4 to the sliding suction cart 3-5. The suction hood C3-2, the sliding suction cart 3-5, and the processing machine move together. A sealing belt seals the connection between the sliding suction cart 3-5 and the sliding air duct 3-6. The collected fumes are sent through the sliding air duct 3-6 and the pipe to the dust collector C3-7 for purification and treatment, and then discharged indoors or outdoors as needed. Each point can be individually controlled via an electric valve C3-3 according to the on-site usage.
[0048] Secondary dust removal system: For production lines with fast cycle times, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when materials enter or exit the work area, the electric lifting door 1-2 opens, causing some smoke and dust to overflow from the work area; or, due to the movement of processing machines, some smoke may overflow from the arc-blocking curtain at the location of the machine movement; secondary collection and purification are carried out on the overall relative location of the factory building. Depending on the on-site process requirements, the electric valve D4-2 of the corresponding area return air vent 4-1 at the top of the workshop can be opened for treatment. Smoke and dust at the top of the factory building are captured and collected by return air vent 4-1, and sent to dust collector D4-4 for purification through electric valve D4-2 and return air duct 4-3. The purified clean air is then sent to the indoor or outdoor areas through air supply duct 4-6, electric valve E4-7, and electric valve F4-8, respectively.
[0049] During winter, the indoor exhaust electric valve E4-7 controls the majority of the air supply to the air duct 4-10 next to the indoor plant column 5, while the outdoor exhaust electric valve F4-8 controls a small portion to the outside, enabling energy reuse and continuously diluting the overall dust concentration in the workshop to meet environmental requirements. The air ducts for each area can be controlled separately via electric valve G4-9 according to site requirements and worker operations.
[0050] During the summer, the outdoor exhaust electric valve F4-8 controls the flow of all air to the outside, thereby removing hot fumes from the workshop, reducing the ambient temperature, and continuously diluting the overall dust concentration in the workshop to meet the environmental requirements.
[0051] If the present invention discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integral molding process).
[0052] Furthermore, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model include states or shapes that are similar to, analogous to, or close to those states or shapes. Any component provided by this utility model can be assembled from multiple individual components or can be a single component manufactured using a one-piece molding process.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
