Description

Technical Field

[0001] This utility model relates to the field of waste gas recovery technology, and in particular to a waste gas recovery and treatment device for a cleanroom. Background Technology

[0002] In modern industrial production, cleanrooms serve as core workspaces in fields such as precision manufacturing, pharmaceutical research and development, and the production of precision electronic components, meeting extremely high requirements for air cleanliness. However, even in strictly controlled cleanroom environments, various types of waste gases are inevitably generated during production. These waste gases are complex in composition and may contain harmful substances such as volatile organic compounds, fine particulate impurities, and chemical reactant residues. Direct emission of these gases would not only pollute the surrounding environment but could also affect the cleanliness of the cleanroom itself due to waste gas recirculation, thereby impacting product quality and production safety. Therefore, in actual production processes, waste gas recovery and treatment devices are typically installed to treat the production waste gases from cleanrooms.

[0003] Existing cleanroom exhaust gas recovery and treatment devices are difficult to maintain long-term connection stability of the device's pipelines due to operational vibrations and other reasons during use, and they are also unable to effectively perform preliminary purification and filtration of the generated exhaust gas. Utility Model Content

[0004] Based on this, the present invention provides a cleanroom waste gas recovery and treatment device with high pipeline connection stability and effective preliminary filtration of waste gas.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A cleanroom exhaust gas recovery and treatment device includes a placement platform. An outlet pipe is installed at one end of the placement platform. Slide rails are provided at both the upper and lower ends of the outlet pipe. An upper clamping frame and a lower clamping frame, connected by fastening rods, are respectively installed at the upper and lower ends of the outlet pipe. The outlet pipe is connected via a connecting pipe to a preliminary purification frame located at the upper end of the placement platform. A filter screen is provided at the front end of the preliminary purification frame. A filter frame and a filter element are installed inside the preliminary purification frame. Partition plates are installed at both the front and rear ends of the filter frame. A closing plate is installed at the upper end of the filter frame, and a top cover is installed at the upper end of the closing plate. An air inlet pipe is installed at the front end of the filter frame, and a filter plate is installed at the front end of the air inlet pipe.

[0007] Furthermore, both the upper clamping frame and the lower clamping frame are connected to the outlet pipe via slide rails to form a sliding structure.

[0008] Furthermore, the lower clamping frame has the same specifications as the upper clamping frame, and the lower clamping frame is threadedly connected to the upper clamping frame by a fastening rod.

[0009] Furthermore, both the filter screen and the filter frame are snapped together with the preliminary purification frame.

[0010] Furthermore, the filter element is snapped into the filter frame, and the filter frame is tightly fitted to the partition plate.

[0011] Furthermore, the air inlet pipe is snapped into connection with the filter plate, and the air inlet pipe is sealed to the preliminary purification frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model comprises a placement platform, a preliminary purification frame, a filter screen, a filter frame, a filter element, a partition plate, a closing plate, and a top cover. The filter screen intercepts larger particulate impurities in the exhaust gas, preventing them from entering subsequent treatment stages. The filter element utilizes its excellent adsorption properties to preliminarily adsorb and filter harmful substances in the exhaust gas, effectively reducing the pollutant content and laying a good foundation for subsequent deep treatment. The partition plate further optimizes the internal structure of the preliminary purification frame, rationally dividing the purification space and guiding the exhaust gas to flow along a preset path, ensuring full contact between the exhaust gas and the filter screen and filter element, thus improving purification efficiency. The closing plate and top cover together form a sealed structure for the preliminary purification frame, ensuring tight closure during exhaust gas purification to prevent leakage of untreated exhaust gas, guaranteeing orderly purification work in a closed environment, and avoiding secondary pollution to the surrounding environment.

[0014] 2. This utility model, through its placement platform, outlet pipe, slide rail, upper clamping frame, lower clamping frame, and fastening rod, provides precise guidance for the movement of the upper and lower clamping frames via the slide rails on the outlet pipe. When connecting the device to an external pipeline, the operator can easily move the upper and lower clamping frames back and forth using the slide rails. This movable design allows the clamping frames to be flexibly adjusted according to the connection position of the external pipeline, thus accurately blocking the connection point between the device and the external pipeline. By tightening the fastening rod, the operator can firmly fix the upper and lower clamping frames in their current positions, ensuring they fit tightly against both sides of the connection point. This effectively prevents the connection from loosening or even falling off during exhaust gas transportation due to pressure changes, vibrations, or other factors, providing a reliable anti-detachment function.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-4 As shown, a cleanroom waste gas recovery and treatment device includes a placement platform 1. An outlet pipe 2 is installed at one end of the placement platform 1. Slide rails 3 are provided at both the upper and lower ends of the outlet pipe 2. An upper clamping frame 4 and a lower clamping frame 5, connected by fastening rods 6, are respectively installed at the upper and lower ends of the outlet pipe 2. The outlet pipe 2 is connected to a preliminary purification frame 8 located at the upper end of the placement platform 1 via a connecting pipe 7. A filter screen 9 is provided at the front end of the preliminary purification frame 8, and a filter frame 10 is installed inside the preliminary purification frame 8. A filter element 11 is installed inside the filter frame 10. Partition plates 12 are installed at both the front and rear ends of the filter frame 10. A closing plate 13 is installed at the upper end of the filter frame 10. A top cover 14 is installed at the upper end of the closing plate 13. An air inlet pipe 15 is installed at the front end of the filter frame 10. A filter plate 16 is installed at the front end of the air inlet pipe 15. The upper clamping frame 4 and the lower clamping frame 5 installed in the device can fix the pipe connection in the upper and lower positions to prevent the connection from falling off after fixing and maintain the stability of the pipe connection.

[0022] In this embodiment, the upper clamping frame 4 and the lower clamping frame 5 are further configured to slide together with the outlet pipe 2 via the slide rail 3.

[0023] In this embodiment, the lower clamping frame 4 and the upper clamping frame 5 are of the same specifications, and the lower clamping frame 4 is threadedly connected to the upper clamping frame 5 by a fastening rod 6.

[0024] In this embodiment, the filter screen 9 and the filter frame 10 are further engaged with the preliminary purification frame 8; the preliminary purification frame 8 installed in the device can filter the exhaust gas through its internal structure, better adsorb and treat the exhaust gas, and facilitate the cleaning of the preliminary purification frame 8. The engaging connection is a commonly used sealed opening and closing structure in the art, and any structure that can achieve a sealed engaging connection can be applied to this application and achieve its technical effect.

[0025] In this embodiment, the filter element 11 is further engaged with the filter frame 10, and the filter frame 10 is tightly fitted with the partition plate 12.

[0026] In this embodiment, the air inlet pipe 15 is further engaged with the filter plate 16, and the air inlet pipe 15 is sealed to the preliminary purification frame 8.

[0027] Working Principle: In use, the device connects to the exhaust gas pipeline of the cleanroom via the air inlet pipe 15. A filter plate 16 installed at the front end of the air inlet pipe 15 separates the air inlet pipe 15 from the cleanroom, allowing exhaust gas to be collected through the preliminary purification frame 8 within the device. Once the exhaust gas enters the preliminary purification frame 8, it undergoes preliminary filtration through the filter element 11 installed inside the frame. The partition plate 12 optimizes the internal structure of the preliminary purification frame 8, rationally dividing the purification space and guiding the exhaust gas along a preset path, ensuring proper filtration of the exhaust gas from the filter screen 9 and filter element 11. Sufficient contact is ensured to improve purification efficiency. The closing plate 13 and the top cover 14 together form the sealing structure of the preliminary purification frame 8, which can tightly close during the waste gas purification process to prevent leakage of untreated waste gas, ensuring that the purification work is carried out in an orderly manner in a closed environment and avoiding secondary pollution to the surrounding environment. By tightening the fastening rod 6, the operator can firmly fix the upper clamping frame 4 and the lower clamping frame 5 in their current positions, so that they fit tightly against both sides of the connection position, effectively preventing the connection position from loosening or even falling off due to pressure changes, vibrations, and other factors during the waste gas transportation process, thus playing a reliable anti-detachment role. All contents not described in detail in this specification are prior art known to those skilled in the art.
