Description

Technical Field

[0001] The utility model relates to the technical field of gas supply, in particular to a centralized gas supply device for a physical and chemical laboratory. Background Art

[0002] On-site gas supply means that an air products manufacturing enterprise (hereinafter referred to as the manufacturing enterprise) rents a site at the site of an air products using unit (hereinafter referred to as the using unit) to build a remotely automatically controlled production device or storage facility to produce air products or store liquid or compressed air products, and provides air products to the using unit through industrial pipelines in an unattended production and supply mode.

[0003] However, in the prior art, during the process of collecting air by existing equipment, some dust and other impurities will be mixed in the air, which will affect subsequent processing and use, thus being unfavorable for actual production and application. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a centralized gas supply device for a physical and chemical laboratory.

[0005] The utility model is realized by adopting the following technical scheme: A centralized gas supply device for a physical and chemical laboratory includes a filtering box. Inside the filtering box, a first conveying pipe is fixedly connected. One end of the first conveying pipe extends above the filtering box and is fixedly connected to a filtering pipe. Inside the filtering pipe, a filter screen is fixedly connected. One end of the filter screen communicates with the first conveying pipe. One end of the filtering pipe is fixedly connected to a second conveying pipe. The filtering pipe communicates with the second conveying pipe. The end of the second conveying pipe away from the filtering pipe is fixedly connected to an air inlet hood, and an air inlet fan is fixedly installed inside the air inlet hood.

[0006] Through the above technical scheme, the air inlet fan works to convey the outside air to the air inlet hood. The air inlet hood conveys the air to the second conveying pipe to make the air enter the filtering pipe. The filter screen works to filter the dust in the air. The filtered air will enter the inside of the filtering box along the first conveying pipe, and the air can be further filtered by water.

[0007] As a further improvement of the above scheme, a collection hood is fixedly connected to the top of the inner wall of the filtering box and on the outside of the first conveying pipe. Condensing sheets are fixedly connected to the outside of the collection hood. Through holes are opened on the outside of the collection hood. Two baking ovens are fixedly connected to the inner wall of the filtering box, and baking blocks are fixedly connected to the inside of the two corresponding baking ovens.

[0008] Through the above technical scheme, the baking blocks work to raise the temperature of the air. When the air with increased temperature contacts the condensing sheets, the moisture contained in the air can be solidified, thereby making the air dry.

[0009] As a further improvement of the above solution, a protective cover is fixedly connected to one end of the air inlet hood away from the second delivery pipe, and air inlet holes are evenly arranged on the outer side of the protective cover.

[0010] Through the above technical solution, the working of the air inlet fan allows external air to enter the interior of the protective cover through the air inlet holes.

[0011] As a further improvement of the above solution, a support plate is fixedly connected to the top of the filter box. The support plate is fixedly connected to the filter pipe. A gas supply pipe is fixedly connected to the top of the filter box and on one side of the first delivery pipe. A solenoid valve is fixedly installed on the outer side of the gas supply pipe.

[0012] Through the above technical solution, the support plate supports the filter pipe, making the filter pipe more stable with the air inlet hood. The solenoid valve can remotely switch the gas supply pipe.

[0013] As a further improvement of the above solution, a water inlet pipe is fixedly connected to the outer side of the filter box. A drain pipe is fixedly connected to the outer side of the filter box and below the water inlet pipe.

[0014] Through the above technical solution, the water inlet pipe can be used to fill the filter box with purified water, and the drain pipe can discharge the used purified water.

[0015] As a further improvement of the above solution, glass covers are fixedly connected to both sides of the water inlet pipe on the outer side of the filter box.

[0016] Through the above technical solution, the transparency of the glass covers can be used to see whether the purified water in the filter box needs to be replaced.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] In the present utility model, the working of the air inlet fan is used to convey external air to the air inlet hood. The air inlet hood conveys the air to the second delivery pipe to allow the air to enter the filter pipe. The working of the filter screen filters the dust in the air. The filtered air will enter the interior of the filter box along the first delivery pipe, and the air can be further filtered by water;

[0019] The utility model makes the air temperature rise through the operation of the baking block. When the heated air contacts the condensation sheet, the moisture contained in the air can be solidified, thereby drying the air. The external air enters the interior of the protective cover through the intake fan from the intake hole. The support plate supports the filter pipe, making the filter pipe and the intake cover more stable. The solenoid valve can remotely control the opening and closing of the air supply pipe. The water inlet pipe can be used to fill the filter tank with purified water, and the drain pipe can discharge the used purified water. Through the transparency of the glass cover, it can be seen whether the purified water in the filter tank needs to be replaced. Description of the Drawings
