Description

Lifting device for the top cover of the oil-gas separator in the screw compressor

technical field

The utility model relates to an oil-gas separator in a screw compressor, in particular to a screw-up device for the top cover of the oil-gas separator. the

Background technique

Since the filter element installed in the oil-gas separator needs to be replaced regularly, the top cover needs to be removed to replace the filter element. The existing structure requires a forklift or driving when removing the top cover. In some unconditional places, two service personnel are required to lift the top cover down, which is time-consuming and laborious. the

As shown in Figure 1: the top cover 1 of the oil-gas separator in the screw compressor in the prior art uses lifting bolts, and the lifting bolts need to be fixed with ropes during disassembly, and the top cover is removed by driving or forklift lifting the ropes, and then the filter element is replaced. . If there is no forklift or driving on the compressor operation site, service personnel need to lift the top cover manually, which is time-consuming, laborious and unsafe. the

Contents of the invention

The technical problem to be solved by the utility model is to provide a top cover screwing device of an oil-gas separator in a screw compressor, aiming at solving the above-mentioned problems. the

In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

The utility model includes: the top cover of the oil-gas separator; also includes: a wire rod, a hand wheel, a rotating arm and an oil-gas separation cylinder support; the oil-gas separation cylinder support is fixed on the side of the top of the oil-gas separation cylinder; One end of the rotating arm is rotatably fixed to the support of the oil-gas separation cylinder, and the other end of the rotating arm is connected to the screw rod arranged on the top cover of the oil-gas separator; the handwheel is connected to the screw rod in rotation. the

Compared with the prior art, the utility model has the beneficial effects that when the oil-gas separation filter element is replaced, the work of removing the top cover becomes easy and fast. the

Description of drawings

Fig. 1 is the structural representation of the oil-gas separator in the screw compressor in the prior art;

Fig. 2 is a structural schematic diagram of the utility model. the

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

It can be seen from Fig. 2 that the utility model includes: the top cover 1 of the oil-gas separator; It is fixed on the side of the top of the oil-gas separation cylinder; one end of the rotating arm 13 is fixed to rotate with the support 14 of the oil-gas separation cylinder, and the other end of the rotating arm 13 is connected to the oil-gas separator top cover 1. The screw mandrel 1 is connected; the hand wheel 12 is connected to the screw mandrel 11 in rotation. the

The working principle of the utility model is: tighten the hand wheel by hand, because the screw rod and the top cover are fixed together, when the hand wheel is tightened, the screw rod will drive the top cover to rise together; when it rises about 30-40mm, it can Push the swivel arm to rotate around the support on the cylinder, and the filter element can be replaced when the top cover is completely removed from the cylinder position. the

Claims (1)
