[0002] As a closed space with highly controlled air cleanliness, temperature, humidity, pressure and other parameters, the waste gas treatment device in a clean room needs to take into account both high-efficiency purification and operation stability. However, there are still many deficiencies in the existing technology when dealing with clean room waste gas, and the specific problems are as follows:

[0003] Traditional filter components mostly adopt static designs, such as fixed-packed activated carbon or single-layer filter screens, resulting in a limited contact area between waste gas and filter media and low adsorption efficiency. Especially for volatile organic compounds (VOCs) or fine particles, static filtration is prone to cause local clogging of filter holes in the filter screen, reducing the overall purification efficiency.

[0004] Therefore, we provide an independent waste gas treatment device for a clean room to solve the above-mentioned problems. Content of the Utility Model

Detailed Implementation Modes

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] Please refer to Figures 1 to 7 , as an embodiment of the present invention, an independent treatment device for clean room waste gas includes a frame 1, a purification box 2 is arranged on the frame 1, a waste collection box 3 is arranged at the bottom of the purification box 2, a mounting rack 4 is arranged inside the purification box 2, a conical cylinder 5 is arranged on the mounting rack 4, a filter cartridge 10 is rotatably installed inside the conical cylinder 5, the filter cartridge 10 penetrates through the conical cylinder 5 and one end extends to the outside of the conical cylinder 5, filter holes 11 are uniformly opened on the filter cartridge 10, propeller blades 12 are arranged on the outer wall of the filter cartridge 10, a waste discharge pipe 13 communicating with the inside of the conical cylinder 5 is arranged at one end bottom of the conical cylinder 5, and an air inlet mechanism for introducing air into the inside of the filter cartridge 10 is arranged on the purification box 2;

[0029] The filter holes 11 are spirally distributed perpendicular to the axis of the filter cartridge 10 along the surface of the filter cartridge 10, and the pitch of the spiral distribution is equal to that of the propeller blades 12.

[0030] In this embodiment, during use, the exhaust gas in the clean room is continuously inflated into the filter cartridge 10 through the air intake mechanism. The exhaust gas entering the filter cartridge 10 by the rotation of the filter cartridge 10 will generate a centrifugal force during rotation. Therefore, under the action of the centrifugal force, the large-mass impurity particles in the exhaust gas will be thrown towards the inner wall of the filter cartridge 10 and enter the conical cylinder 5 through the filter holes 11 opened on the filter cartridge 10, thereby removing the impurities in the exhaust gas in the filter cartridge 10. The purified air is lighter in mass, so it accumulates at the central axis of the filter cartridge 10 and is discharged outward from one end of the filter cartridge 10 under the impact of the newly incoming air flow, thus achieving the purpose of exhaust gas purification. Since the rotation of the filter cartridge 10 will also drive the propeller blades 12 on the outer wall of the filter cartridge 10 to rotate, the spiral rotation of the propeller blades 12 can also helically transport the impurity particles thrown into the inner cavity of the conical cylinder 5 and gradually accumulate at one end of the conical cylinder 5 and finally be discharged outward through the waste discharge pipe 13.

[0031] As a further solution of the present invention, a bearing seat 9 is provided on the mounting frame 4, and the filter cartridge 10 is rotatably mounted on the bearing seat 9.

[0032] In this embodiment, since a bearing seat 9 is provided on the mounting frame 4 and the filter cartridge 10 is rotatably mounted on the bearing seat 9, and the conical cylinder 5 is fixed on the mounting frame 4, the filter cartridge 10 can rotate within the conical cylinder 5.

[0033] As a further solution of the present invention, the air intake mechanism includes a blower housing 6 fixed to the purification box 2. An air inlet pipe 15 and an exhaust net 17 are installed on the blower housing 6. A rotating shaft 16 is rotatably provided on the blower housing 6, and an impeller 18 disposed inside the blower housing 6 is provided on the rotating shaft 16.

[0034] In this embodiment, when the rotating shaft 16 rotates, it will drive the impeller 18 to rotate to generate a negative pressure inside the blower housing 6. Therefore, the exhaust gas in the clean room is extracted to the inner side of the blower housing 6 through the blower housing 6 and finally discharged outward through the exhaust net 17, achieving the purpose of continuously extracting the exhaust gas in the clean room.

[0035] As a further solution of the present invention, a motor 14 is provided on the purification box 2, and the output end of the motor 14 is connected to the rotating shaft 16 through a coupling to drive the rotating shaft 16 to rotate.

[0036] In this embodiment, the motor 14 is electrically connected to an external power supply through a wire. Starting the motor 14 can drive the rotating shaft 16 to rotate, and when the rotating shaft 16 rotates, it will drive the impeller 18 to rotate.

[0037] As a further solution of the present utility model, a gas collecting hood 7 is arranged on one side of the exhaust net 17. A gas guide pipe 8 fixedly connected to the rotating shaft 16 is rotatably installed on the gas collecting hood 7. The gas guide pipe 8 is fixed to the filter cartridge 10, and the gas guide pipe 8 is communicated with the inside of the gas collecting hood 7 and the filter cartridge 10.

[0038] In this embodiment, when the rotating shaft 16 rotates, it will drive the impeller 18 to rotate to generate negative pressure inside the fan housing 6. Therefore, the exhaust gas in the clean room is extracted to the inner side of the fan housing 6 through the fan housing 6, and finally discharged outward through the exhaust net 17 and reaches the inside of the gas collecting hood 7. The gas guide pipe 8 is communicated with the inside of the gas collecting hood 7 and the filter cartridge 10. Therefore, the exhaust gas in the gas collecting hood 7 is finally conveyed to the inside of the filter cartridge 10 through the gas guide pipe 8.

[0039] As a further solution of the present utility model, the outer diameter dimension of the propeller blade 12 is adapted to the inner diameter dimension of the conical cylinder 5.

[0040] In this embodiment, the inner diameter dimension of the conical cylinder 5 gradually decreases from one end to the other end, and the outer diameter dimension of the propeller blade 12 also gradually decreases from one end to the other end. The outer diameter dimension of the propeller blade 12 is adapted to the inner diameter dimension of the conical cylinder 5. The propeller blade 12 rotates spirally and cooperates with the conical cylinder 5 to convey the impurity particles thrown into the inner cavity of the conical cylinder 5 in a spiral manner, and makes the impurity particles gradually accumulate and gather at one end of the conical cylinder 5 and finally be discharged outward through the waste discharge pipe 13. The impurity particles entering the inside of the waste discharge pipe 13 fall into the waste collection box 3 for collection.

[0041] As a further solution of the present utility model, a discharge port is opened at the bottom of the waste collection box 3, and a sealing plug is movably clamped in the discharge port.

[0042] In this embodiment, the impurity particles gradually accumulate and gather at one end of the conical cylinder 5 and finally be discharged outward through the waste discharge pipe 13. The impurity particles entering the inside of the waste discharge pipe 13 fall into the waste collection box 3 for collection. After the exhaust gas purification is completed, the sealing plug is taken out, and the impurity particles collected inside the waste collection box 3 are centrally discharged and collected.

[0043] In use, this device is installed in a clean room. Starting the motor 14 can drive the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it will drive the impeller 18 to rotate. When the impeller 18 rotates, a negative pressure is generated inside the blower housing 6. Therefore, the exhaust gas in the clean room is extracted to the inner side of the blower housing 6 through the blower housing 6 and finally discharged to the inside of the air collecting hood 7 through the exhaust net 17. The air guide pipe 8 is communicated with the inside of the air collecting hood 7 and the filter cartridge 10. Therefore, the exhaust gas in the air collecting hood 7 is finally transported to the inside of the filter cartridge 10 through the air guide pipe 8, continuously filling the exhaust gas in the clean room into the filter cartridge 10. The exhaust gas entering the filter cartridge 10 through rotation will generate centrifugal force during rotation. Therefore, under the action of the centrifugal force, the large-mass impurity particles in the exhaust gas will be thrown towards the inner wall of the filter cartridge 10 and enter the conical cylinder 5 through the filter holes 11 opened on the filter cartridge 10, thereby removing the impurities in the exhaust gas inside the filter cartridge 10. The purified air has a lighter mass, so it accumulates at the central axis of the filter cartridge 10 and is discharged outward from one end of the filter cartridge 10 under the impact of the newly incoming air flow, thus achieving the purpose of exhaust gas purification. Since the rotation of the filter cartridge 10 will also drive the propeller blades 12 on the outer wall of the filter cartridge 10 to rotate, the impurity particles thrown into the inner cavity of the conical cylinder 5 can be spirally transported through the spiral rotation of the propeller blades 12 and gradually accumulate at one end of the conical cylinder 5 and are finally discharged outward through the waste discharge pipe 13.

[0044] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present invention, all technical solutions that can implement the present invention in other specific forms are included in the present invention.
