Description

Technical Field

[0001] The utility model belongs to the technical field of smelting equipment, and particularly relates to a device for transporting special materials by gas. Background Art

[0002] At present, in most metallurgical and chemical industries, it involves using powdery materials as medicaments or adjuvants and adding them to the production process or products. For example, in the chemical industry, polyacrylamide powdery medicament is used. It has good water absorption, is easy to get damp and agglomerate in nature, forms a gel-like substance which is not convenient for storage, and if the addition amount is too much at one time during the addition process, large glue blocks are easily formed in the stirring device and are difficult to dissolve. During the actual operation by employees, uniform addition cannot be achieved, which easily causes waste of materials. For example, in the chemical and pharmaceutical industries, some of the materials used are prone to oxidation reaction during the contact with air, resulting in changes in the properties of the materials, thus affecting the use effect or the quality of the produced products. Content of the Utility Model

One side above the material storage tank is connected to a nitrogen gas pipeline Ⅰ, and the nitrogen gas pipeline Ⅰ is connected to a nitrogen gas tank. An upper pressure gauge and an intake valve are provided on the nitrogen gas pipeline Ⅰ. The other side above the material storage tank is connected to a stirring tank through an exhaust pipe, and an exhaust valve is provided on the exhaust pipe. One end of the material conveying tee is connected to a nitrogen gas storage tank through a nitrogen gas pipeline Ⅱ.

[0008] The beneficial effects of the present utility model are as follows: After storing materials in the material storage tank of the present utility model, nitrogen is introduced to isolate the materials from the outside air, preventing the materials from getting damp and caking or undergoing oxidation reactions; nitrogen is sent into the material conveying three-way pipe through the nitrogen pipeline, and is decompressed by a pressure reducing regulator during this process.

[0013] Refer to the attached Figure 1, A device for transporting special materials by gas, comprising a material storage tank 2. A conical feeding tank 1 is provided at the upper part of the material storage tank 2. A grid sieve 4 is provided in the conical feeding tank 1. A feed valve 5 is provided below the conical feeding tank 1. A discharge valve 8 is provided on the lower discharge pipe of the material storage tank 2. The lower part of the discharge pipe is connected to a material conveying tee 21. One side above the material storage tank 2 is connected to a nitrogen gas pipeline I 19. The nitrogen gas pipeline I 19 is connected to a nitrogen gas tank 3. An upper pressure gauge 14 and an intake valve 13 are provided on the nitrogen gas pipeline I 19. Nitrogen gas enters the upper part of the material storage tank 2 through the nitrogen gas pipeline I 19, the intake valve 13 and the upper pressure gauge 14 to purge the upper space of the material storage tank. The other side above the material storage tank 2 is connected to a stirring tank 11 through an exhaust pipe 10. An exhaust valve 12 is provided on the exhaust pipe 10. One end of the material conveying tee 21 is connected to the nitrogen gas tank 3 through a nitrogen gas pipeline II 20. A pressure reducing regulator 17, a lower pressure gauge 22 and a nitrogen gas valve 18 are provided on the nitrogen gas pipeline II 20. Nitrogen gas enters the material conveying tee after being decompressed and the material is evenly added to the stirring tank by adjusting the nitrogen gas valve 18 using the gas velocity. The other end of the material conveying tee 21 is connected to the stirring tank 11, and the outlet of the material conveying tee enters the stirring tank 11. A vibrator 6 is provided on the outer tank wall of the material storage tank 2. A material detection sensor 9 is provided at the connection of the lower discharge pipe of the material storage tank 2 and the material conveying tee 21. The material detection sensor 9 is connected to the vibrator 6 to ensure the fluidity of the material in the tank. An upper sight glass 15 and a lower sight glass 16 are respectively provided at the upper part and the upper part of the material storage tank 2. A drain valve 7 is provided at the lower part of the material storage tank 2.

[0014] First, open the feed valve 5, add the material into the conical feeding tank 1, and enter the material storage tank 2 through the grid sieve 4. When the added amount of the material reaches the upper sight glass 15, stop adding the material, close the feed valve 5 to ensure no air leakage, then open the exhaust valve 12 on one side of the material storage tank 2, and then open the intake valve 13 to introduce nitrogen gas into the material storage tank to displace the gas in the upper space of the material storage tank 2, and then close the exhaust valve 12. According to the value shown on the upper nitrogen gas pressure gauge 14, fill a certain pressure of nitrogen gas into the material storage tank 2. During the addition of the bottom material, first close the nitrogen gas valve 18, observe the pressure of the lower pressure gauge 22 by adjusting the pressure reducing regulator 17 to ensure that the pressure of the lower pressure gauge 22 is lower than that of the upper pressure gauge 14, then slightly open a part of the nitrogen gas valve 18 to form a certain gas flow velocity, and then slowly open the discharge valve 8. The material enters the material conveying tee 21 and the material is slowly added to the stirring tank 11 by the gas velocity to ensure that the powdery medicament is not affected by moisture and does not undergo oxidation reaction. If it is not used for a long time, the drain valve 7 can be opened to empty the material in the material storage tank 2.

[0015] Specifically, the sundries and lumpy materials in the materials are filtered out through the inner grid screen of the conical feeding trough, and the qualified materials enter the material storage tank for storage. Nitrogen is introduced into the upper space of the material storage tank for gas replacement. When adding materials, after the pressure of nitrogen is reduced by the pressure reducing regulator, it enters the material conveying tee through the nitrogen valve. Nitrogen forms a certain gas velocity in the material conveying tee, and the materials are evenly added to the stirring device. This device can ensure that the materials are not affected by moisture and do not undergo chemical reactions during the whole conveying process, and can be evenly added according to production requirements, achieving refined control.
