Embodiment 1

[0019] Such as figure 1 As shown, this embodiment includes a cylinder body 2 and an upper cover 7, the cylinder body 2 is provided with an air inlet 1 and an air outlet port 3, the bottom of the cylinder body 2 is provided with a drain valve 5, and a filter element 4 is installed inside the cylinder body 2, The filter element 4 communicates with the air inlet 1, the air outlet 3 communicates with the inside of the cylinder body 2, the cylinder body 2 is connected with the upper cover 7 through the eyebolt 6, the top of the upper cover 7 is connected with the handwheel 8 through the screw, and the top of the upper cover 7 is connected with the screw The threaded fit also includes a rotating arm 9 arranged on the barrel 2, and the end of the rotating arm 9 is threadedly connected with the screw rod. The upper part of the cylinder 2 is connected and fixed with the external mounting frame by welding, and the bottom of the cylinder 2 is equipped with a drain valve, which can not on...

Embodiment 2

[0022] Such as figure 1 As shown, on the basis of Embodiment 1, this embodiment also includes a differential pressure gauge arranged on the surface of the cylinder body 2, and the two ends of the differential pressure gauge communicate with the air inlet 1 and the air outlet 3 respectively. Generally, the filter will be cleaned regularly, but due to uncertain factors, the filter element net will be damaged, and the failure to clean and check in time will greatly reduce the filtering effect of natural gas; the differential pressure gauge can indicate the pressure change value at the front and rear ends of the filter in real time, It provides a scientific basis for the filter to count the appropriate cleaning time, saves cost, time, and facilitates maintenance, and can effectively save energy and reduce consumption.

Abstract

The invention discloses a quick-opening natural gas filter which comprises a barrel body and an upper cover, wherein an air inlet and an air outlet are formed in the barrel body, a blow-down valve is arranged at the bottom of the barrel body, a filter core is arranged inside the barrel body and is communicated with the air inlet, the air outlet is communicated with the inside of the barrel body, the barrel body is connected with the upper cover through an eyebolt, the top of the upper cover is connected with a hand wheel through a screw rod, and the top of the upper cover is matched with the screw rod through a thread. The quick-opening natural gas filter further comprises a rotary arm arranged on the barrel body, wherein the end part of the rotary arm is connected with the screw rod through a thread. After being used for a long time, the quick-opening natural gas filter needs to be cleaned, the upper cover and the barrel body are separated by rotating the eyebolt, and meanwhile the hand wheel at the top of the upper cover is regulated, the upper cover is lifted up for a distance, the upper cover and the barrel body are misplaced through rotating the rotary arm, and then the filter core is quickly taken out for being cleaned; compared with a conventional flange bolt connection mode, the quick-opening natural gas filter has the advantages that the time of opening the cover of the filter is greatly shortened, the labor intensity of workers is reduced, and the work efficiency is increased.

Description

technical field [0001] The invention relates to a filter, in particular to a quick-open natural gas filter. Background technique [0002] A quick opening natural gas filter is often used in the transmission and distribution of town gas. The natural gas entering the gas distribution station always contains a small amount of micron or submicron impurities due to long-distance transportation or other reasons (natural gas will corrode the inner wall of the pipeline, the upper gas gathering station, purification plant or gas distribution station Separation, dedusting, and purification of natural gas (residual impurities after purification) affect the normal and stable operation of the pressure regulator and metering device in the station, so the last station that supplies gas to users must purify and remove dust from the upper level to ensure Smooth air supply. [0003] At present, for the filters on the market, in order to ensure the stable air supply of precision equipment su...
