Description

Technical Field

[0001] This application belongs to the field of exhaust gas treatment in semiconductor dry etching back-end processes, and in particular relates to a waterproof structure that is extremely important during the transportation of exhaust gas purifiers. Background Technology

[0002] The back end of semiconductor dry etching generates a large amount of flammable, explosive, and toxic exhaust gases. Existing exhaust gas treatment methods include absorbent adsorption or plasma hydrolysis. Currently, absorbent adsorption is widely used in various integrated circuit factories. During the exhaust gas absorption process, a large amount of substances that are easily hydrolyzed or react with water are generated. Therefore, the waterproof performance of the external container is directly related to its safety.

[0003] The existing exhaust gas elimination tanks have a flat top design for waterproofing, which relies on fasteners and sealing rings. However, exhaust gas elimination tanks are reusable products, and fasteners are prone to loosening during transportation and handling. Sealing rings are also prone to aging after long-term use, which may compromise their sealing performance and pose a significant risk to the personal and property safety of those working in the industry. Utility Model Content

[0004] The purpose of this utility model is to provide a water-proof structure for a pest control bucket. This application not only has a conventional vertical waterproof structure, but also innovatively adds a horizontal waterproof structure, namely the conventional waterproof structure between the fastener connecting block and the waterproof block, as well as a horizontal waterproof wall. Even if the fasteners loosen during transportation and handling, the horizontal waterproof wall will effectively prevent water from entering the bucket, resulting in a significant waterproof effect.

[0005] To address the technical problem of unreliable waterproofing during the transportation and handling of pesticide removal containers in the prior art, this application provides a water-proof structure for pesticide removal containers, which includes a container body and a container lid;

[0006] The upper end of the barrel is open, and the open extends out of the barrel mouth wall in a direction away from the barrel body. Fastener connecting blocks are arranged around the barrel mouth wall. Several fastener connecting holes are evenly opened on the upper end of the fastener connecting blocks. The part of the barrel mouth wall that is higher than the fastener connecting blocks forms a horizontal waterproof wall.

[0007] The barrel lid includes a cover plate and fasteners; a waterproof block is recessed around the periphery of the cover plate, and several through holes are evenly opened in the waterproof block; the fasteners pass through the through holes and are connected to the fastener connection holes; the cover plate has an exhaust gas treatment port.

[0008] Furthermore, the present application provides a water-proof structure for a pest control bucket, which further includes a sealing gasket, the sealing gasket being clamped between the fastener connecting block and the waterproof block.

[0009] Furthermore, the present application provides a water-proof structure for a pest control bucket, which further includes a contoured sealing cap ring. The contoured sealing cap ring covers the upper end of the bucket opening wall, and the bottom part of the contoured sealing cap ring is clamped between the cover plate and the bucket opening wall. The outer edge of the contoured sealing cap ring is recessed and clamped between the fastener connecting block and the waterproof block.

[0010] Furthermore, this application provides a water-proof structure for a pest control bucket, wherein the fastener connecting block and the bucket body are welded together.

[0011] Furthermore, this application provides a water-proof structure for a pest control bucket, wherein the cover plate and the waterproof block are welded together.

[0012] Furthermore, this application provides a water-proof structure for a pest control bucket, wherein a handle structure is welded to the upper end of the cover plate.

[0013] Compared with existing technologies, the water-proof structure of the pest control bucket provided by this utility model has the following advantages: This application not only has a conventional vertical waterproof structure, but also innovatively adds a horizontal waterproof structure, namely, the conventional waterproof structure between the fastener connecting block and the waterproof block, as well as a horizontal waterproof wall. Even if the fasteners loosen during transportation and handling, the horizontal waterproof wall will effectively prevent water from entering the bucket body, resulting in a significant waterproof effect. It can prevent fluid from flowing into the bucket body from the upper part of the lid due to loose fasteners; prevent fluid from flowing into the bucket body from the upper part of the lid due to aging of the sealing ring; and prevent splashing fluid from the outside of the bucket body from flowing into the bucket body due to aging of the sealing ring.
