Technical Field

The invention belongs to the field of air compressors, and particularly relates to a totally-enclosed integrated movable compression cavity.

Background

The compression cavity in the existing reciprocating air compressor structure is composed of two parts of a cylinder body and a piston, and because the compression cavity is combined in a split mode, the phenomenon of air leakage is inevitably generated during working, and in order to stop leakage, a sealing ring needs to be arranged between gaps or the precision of coupling of the compression cavity and the piston is improved. However, the better the sealing performance, the greater the resistance of the piston movement, the higher the precision, the more difficult the manufacturing process, either energy consumption or manufacturing cost.

Disclosure of Invention

Aiming at the problems, the invention provides a totally-enclosed integrated movable compression cavity, which is a closed whole except an air inlet and an air outlet, so that the problem of air leakage of the compression cavity is thoroughly solved.

The invention relates to a totally-enclosed integrated movable compression cavity, which is sleeved in a cylinder body by an outer hoop and an inner bag, and the top of the compression cavity is connected with a piston and moves along with the piston. The outer hoop is hard and has the function of compression resistance; the inner bag is soft and serves to prevent leakage.

The top of the inner bag is connected with the top of the outer hoop into a whole, the bottom of the inner bag is connected with the plane of the upper part of the fixed bedplate into a whole, and the periphery of the bag body is clung to the periphery of the upper part of the inner side of the outer hoop and the inner arc of the fixed bedplate but is not connected. The lower part of the inner bag is fixed up and down, and the periphery is not fixed, so that the totally-enclosed integrated movable compression cavity needs to move up and down.

The bottom of the fixed bedplate is connected with the cylinder body in a closed way, the inner part of the fixed bedplate is in a shape of a Chinese character 'ji', an arc-shaped port is in a shape of a knife edge, an inner bag and an outer hoop are separated, the lower part of the inner bag forms a fold at the inner arc in the movement and extension, and a high-pressure valve and a low-pressure valve are arranged to be communicated with corresponding mechanisms outside. The communication mode is as follows: the high-pressure valve is communicated with the temporary gas storage bin, and the low-pressure valve is communicated with the gas inlet bin. The temporary gas storage bin is connected with the gas storage tank, a high-pressure valve is arranged between the temporary gas storage bin and the gas storage tank, a drain valve is arranged at the bottom of the temporary gas storage bin, the gas inlet bin is connected with the gas inlet pipe, and the gas inlet is provided with a filter.

The totally-enclosed integrated movable compression cavity can be provided with rolling balls or rollers on two sides of a clamping groove formed on the inner side of the cylinder body and the outer side of the fixed bedplate so as to reduce the frictional resistance when the outer hoop moves up and down.

The bottom of the outer hoop is open and is inserted into the clamping groove for movement.

The totally-enclosed integrated movable compression cavity has the following advantages: 1. air leakage does not occur; 2. the friction resistance is small; 3. the preparation is simple, and the precision requirement is not high; 4. compressed air can be produced and processed without high-speed rotation. Therefore, the device is convenient to popularize and use and is excellent equipment for collecting, processing and producing compressed air.
