Description

Technical Field

[0001] The utility model relates to a high-pressure gas discharge protection cover with a dirt suction device, belonging to the field of inspection equipment for special equipment. Background Art

[0002] During the inspection of gas cylinders, a high-pressure air compressor is required. However, when the high-pressure air compressor stops working, it will quickly discharge the high-pressure compressed air in the pipeline. This process will generate a lot of noise, thus causing noise pollution. In addition, during the discharge process, a small amount of oil and sewage will also be discharged. If discharged directly, it will not only cause noise pollution, but also cause sewage splashing, further aggravating environmental pollution.

[0003] For this reason, the applicant has designed a high-pressure gas release protective cover, such as Figure 1 , 2 As shown, its working principle is that the air inlet pipe extends into the protective cover, and the air inlet pipe mouth is a downward elbow. When discharging, high-pressure gas enters, reflects and diffuses back and forth, and after changing the direction of the air flow many times, it is finally discharged from several exhaust ports on the upper part of the shell to reduce pressure and sound, while a small amount of oil and sewage is absorbed by the dirt-absorbing cotton at the bottom.

[0004] Although the amount of oil discharged is small, the absorption capacity of the cotton wool is limited and needs to be replaced regularly, otherwise it will lose its absorption effect after saturation, causing oil and sewage to be directly discharged into the environment. Replacing the saturated cotton wool is also a challenge. Since the cotton wool is located at the bottom of the protective cover, the protective cover needs to be opened when replacing it, which not only increases the workload, but also may affect the efficiency of gas cylinder inspection.

[0005] Therefore, it is necessary to find more effective solutions to deal with the oil and sewage problems generated during the discharge process of high-pressure air compressors. Utility Model Content

[0006] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a high-pressure gas discharge protective cover with a sewage suction device to solve the above problems.

[0007] The utility model discloses a high-pressure gas discharge protective cover with a sewage suction device, comprising a protective cover, an air inlet opening being arranged in the middle of the side surface of the protective cover, a deflection structure being arranged inside the protective cover for changing the direction of the airflow multiple times, a plurality of exhaust ports being arranged at the top of the side surface of the protective cover, and a sewage suction fixing device being arranged around the protective cover at the lower outer side thereof, wherein the sewage suction fixing device comprises a plurality of closely arranged fixed grids, the fixed grids being vertically penetrated, sewage suction cotton blocks being loaded in the fixed grids, and the sewage suction cotton blocks being in contact with the ground.

[0008] The dirt-absorbing cotton block can prevent oil and dirt from flowing outside, and it is easy to replace after the dirt-absorbing cotton block is saturated. The corresponding position can be replaced individually without replacing the whole block. It is simple, efficient and cost-saving.

[0009] The sewage suction fixing device is in the shape of a square ring and is composed of four strip-shaped fixing frames, and a fixed grid is arranged inside the strip-shaped fixing frames.

[0010] Preferably, each fixed grid has the same size.

[0011] Preferably, the dirt-absorbing cotton block is a sponge.

[0012] The outer side surface of the protective cover of the utility model is provided with a plurality of raised limiting blocks, and the plurality of limiting blocks are at the same height and are used for supporting the dirt suction fixing device.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. It provides an effective way to deal with oil pollution: by setting up a sewage suction device, it can effectively absorb and fix oil pollution and sewage, avoiding the direct discharge of oil pollution and sewage into the environment, thus being more environmentally friendly.

[0015] 2. Convenient replacement of the dirt-absorbing cotton block: The dirt-absorbing cotton block is located at the lower part of the outer side of the protective cover and can be easily replaced, avoiding the tedious operation of opening the entire protective cover in the traditional design, thereby improving work efficiency.

[0016] 3. Cost saving: The dirt-absorbing cotton block can be replaced individually at the corresponding position without replacing the whole piece, which reduces the replacement cost.

[0017] 4. Simple structure: The sewage suction fixture adopts a square ring design and consists of four bar-shaped fixing frames. It has a simple and compact structure and is easy to install and use. BRIEF DESCRIPTION OF THE DRAWINGS
