Description

Technical Field

[0001] This utility model belongs to the field of oil-gas separator technology, and in particular relates to a top cover based on an oil-gas separator. Background Technology

[0002] The oil-gas separator used in air compressors mainly separates oil and gas through oil separation. The oil-gas separator mainly consists of a tank, a top cover, and an oil separator. A pressure valve (pressure maintaining valve, minimum pressure valve, etc.) needs to be installed on the top cover. The oil separator is fixed to the top of the tank through the top cover. When the oil separator reaches a certain standard of use, it needs to be replaced or cleaned for maintenance.

[0003] Currently, when replacing the oil separator, it is necessary to first disconnect the connections of the pressure valve and other pipelines on the top cover, then remove the top cover (the connection between the top cover and the tank body uses flanges and bolts, which serve to stabilize and resist pressure), and finally remove the oil separator from bottom to top. Due to the limited space inside the air compressor and the obstruction of the pressure valve and its pipelines, it is difficult to remove, making the operation quite cumbersome. Similarly, obstacles will also occur during the installation process, and it is necessary to ensure the precise positioning of the top cover and the accuracy of the connecting pipes at the pressure valve, thus affecting the installation efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide a top cover based on an oil-gas separator. The top cover structure is composed of an extension sleeve and a cover body. The extension sleeve allows the exhaust to be designed as a side-mounted type, with the exhaust output from the outward protrusion. This ensures that the removal of the cover body is unrelated to the exhaust. The maintenance of the oil separator does not require the installation, positioning, and removal of the pressure valve connection point, reducing the installation and positioning procedures for workers. At the same time, the pressure valve is not located directly above the cover body, avoiding obstruction. This facilitates the installation and removal of the oil separator and reduces the occurrence of bumps and knocks, thus making it easier to maintain the oil-gas separator.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a top cover based on an oil-gas separator, including a cover body and an extension sleeve;

[0007] The extension sleeve has a tank top connecting flange on the outer side of its bottom end, an oil separator support edge on the inner side of its bottom end, an outward protrusion fixedly connected to the circumferential side of the extension sleeve, a cover connecting flange on the top of the extension sleeve, the top surface of the outward protrusion being flush with the cover connecting flange, and a pressure valve interface fixedly connected to the top surface of the outward protrusion.

[0008] The protruding part is provided with vertically arranged threaded columns, the cover connecting flange is provided with several lower mounting ports that are misaligned with the protruding part, and the cover connecting flange is provided with a lower positioning port that is concentrically connected to the threaded columns.

[0009] The cover body is provided with an upper positioning port and several upper mounting ports at its edge. The cover body is fixed to the top of the extension sleeve by several bolts. The bolts are located between the upper mounting port and the lower mounting port, and between the upper positioning port and the lower positioning port.

[0010] The bottom surface of the cover is provided with a pressure sleeve, and the bottom surface of the pressure sleeve is attached to the oil separator support edge to form an oil separator installation point. The peripheral side of the pressure sleeve is provided with a notch, and the notch is opposite to the outward protrusion. The notch is located directly below the upper positioning port of the cover.

[0011] Furthermore, it also includes an oil separator, which includes a screen cylinder section. The top edge of the screen cylinder section is provided with a cylinder edge. The top surface of the oil separator support edge and the bottom surface of the pressure sleeve are both provided with embedding grooves. The cylinder edge is set in the embedding grooves of the oil separator support edge and the pressure sleeve, and the connection is provided with sealant.

[0012] Furthermore, it also includes a tank body, the extension sleeve is fixed to the top of the tank body via a tank top connecting flange, the top of the tank body is provided with an original support edge, the bottom surface of the oil separator support edge is fitted with the original support edge and the connection is sealed.

[0013] Furthermore, the spacing between several lower mounting ports on the cover connecting flange is consistent, and the distance between the upper positioning port and the adjacent lower mounting port is greater than the distance between two adjacent lower mounting ports.

[0014] Furthermore, the top surface of the protruding part is a planar structure, and the bottom surface of the protruding part is an arc-shaped structure.

[0015] Furthermore, the inner diameter of the cover connecting flange is larger than the outer diameter of the cylinder edge, and the outer diameter of the pressure sleeve is consistent with the inner diameter of the cover connecting flange.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model uses an extension sleeve and a cover body to form a top cover structure. The extension sleeve allows the exhaust to be designed as a side-mounted type, with the exhaust output from the outward protrusion. This ensures that the removal of the cover body is unrelated to the exhaust. The maintenance of the oil separator does not require the installation, positioning, and removal of the pressure valve connection point, reducing the installation and positioning procedures for workers. At the same time, the pressure valve is not located directly above the cover body, avoiding obstruction. This facilitates the installation and removal of the oil separator and reduces the occurrence of bumps and knocks, thus making it easier to maintain the oil-gas separator.

[0018] 2. This utility model, through the design of the internally threaded post of the protruding part, together with the upper positioning port of the cover and the lower positioning port of the cover connecting flange, plays a positioning role during the installation process, and avoids the upper and lower positioning ports from communicating with the space inside the tank, thus ensuring the sealing effect. At the same time, the positioning function can ensure that the pressure sleeve is aligned with the position of the protruding part after installation, thus ensuring smooth and unobstructed venting.

[0019] 3. This utility model designs the oil separator installation point on the extension sleeve, so the oil separator can be removed without removing the extension sleeve. At the same time, if the installation wear is caused by excessive maintenance frequency or excessive cleaning of sealant, only the extension sleeve needs to be replaced directly, without replacing the entire separator. That is, there is no need to replace the tank body or remove the various connecting pipes and instruments on the tank, thereby reducing maintenance costs and maintenance time.

[0020] 4. The extension sleeve and cover designed in this utility model can be directly installed on the tank of the old separator when the specifications are the same, so as to achieve the purpose of rapid modification and save modification costs.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
