Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen-making sewage discharge auxiliary equipment, and specifically, to a sewage discharge structure of a nitrogen-making device that prevents blockage. Background Technique

[0002] A nitrogen generator is a device that uses air as a raw material and separates oxygen and nitrogen in it by physical methods to obtain nitrogen. Industrial nitrogen generators can be classified into three types according to different classification methods, namely, cryogenic air separation method, molecular sieve air separation method (PSA), and membrane air separation method. In existing nitrogen-making equipment sewage discharge structures, filters are used to remove impurities and sewage for dust in the air. However, during use, it is easy to cause blockage of the filter due to too large or too many filter particles, thereby affecting the rate of air impurity removal and sewage discharge and the nitrogen-making efficiency.

[0003] For example, the existing Chinese authorized patent (Publication No.: CN 217939672 U) discloses a sewage discharge structure of a nitrogen-making device that prevents blockage, including a sewage discharge tank of a nitrogen generator. On both sides inside the sewage discharge tank of the nitrogen generator, mounting frames are installed, and activated carbon plates are installed on one side of each mounting frame. Slide rails are installed at both ends of the mounting frame. By starting the rotating motor in the utility model, the machine shaft rotates, so that the first gear drives the second gear to rotate, the water supply pipe rotates, and then the cleaning sponge continuously rubs against the surface of the filter screen, that is, the cleaning of the filter screen is realized, so that dust impurities are separated from the surface of the filter screen, effectively preventing blockage of the filter screen. Cooperating with starting the water pump, water flows through the water inlet pipe, through the water outlet pipe, through the water supply pipe, and finally is sprayed out by the nozzle, so that water droplets combine with dust, and the dust falls to the bottom of the shell of the sewage discharge tank of the nitrogen generator, preventing the dust from adhering to the surface of the filter screen again.

[0004] The sewage discharge structure of the nitrogen-making device that prevents blockage designed as above has the following disadvantages in actual use: In the comparison case, it is mentioned that after impurity removal and then dust removal by the filter screen, the air is discharged through the air outlet pipe. If the dust blocks the filter screen, it will cause difficulties in discharge or a decrease in the discharge volume.

[0005] In view of this, a sewage discharge structure of a nitrogen-making device that prevents blockage is provided to overcome the above defects. Content of the Utility Model
