Description

Technical Field

[0001] The utility model belongs to the technical field of gas drying, and in particular relates to a gas filtering and drying device. Background Art

[0002] Dry gas refers to gas that has its moisture content reduced to a low level by removing water, humidity and dissolved gases. Dry gas is required in the pharmaceutical, power, aviation, automotive and other industries. When drying gas, the desiccant needs to be replaced according to the acidity and alkalinity of the gas.

[0003] The principle is to remove moisture, humidity and dissolved gases from the gas by mechanical or chemical methods to achieve the drying effect. There are two commonly used methods: adsorption drying and condensation drying. Adsorption drying is a method of absorbing moisture, humidity and dissolved gases through adsorbents, while condensation drying is a method of condensing moisture and dissolved gases.

The application has the effect of improving the problem of safety hazards in the drying process of acetylene caused by the increase of local temperature of acetylene.

[0005] However, the above structure still has some shortcomings. When the acetylene gas drying and filtering device is used, it is not convenient to quickly replace the drying tower, and the ability to dry different gases is insufficient.

[0006] Therefore, it is necessary to provide a new gas filtering and drying device to solve the above technical problems. Utility Model Content

The gas filter drying device comprises: a base 1, on which an adjustment device and two convenient replacement devices are arranged;

[0027] The adjusting device comprises a fixed tube 2, a threaded rod 3, a bearing 4, an upper cover 5 and a rotating handle 6, wherein the fixed tube 2 is fixedly mounted on the top surface of the base 1, the threaded rod 3 is threadedly connected to the fixed tube 2, the inner wall of the bearing 4 is fixedly connected to the threaded rod 3, the upper cover 5 is fixedly connected to the outer wall of the bearing 4, and the rotating handle 6 is fixedly connected to the top of the threaded rod 3;

[0028] The convenient replacement device includes a semi-dry tube 7, a fixing ring 8, four spring telescopic rods 9, a closing plate 10, a top tube 11, a vent hole 12, a sealing rubber pad 13 and a sealing pad 14. The semi-dry tube 7 is arranged below the upper cover 5. The fixing ring 8 is fixedly connected to the inner wall of the semi-dry tube 7. The four spring telescopic rods 9 are fixedly installed on the top surface of the fixing ring 8. The closing plate 10 is fixedly connected to the top surface of the four spring telescopic rods 9. The top tube 11 is arranged directly below the fixing ring 8. The vent hole 12 is opened on the outer wall of the top tube 11. The sealing rubber pad 13 is fixedly connected to the outer wall of the top tube 11. The sealing pad 14 is fixedly connected to the bottom surface of the closing plate 10.

[0029] A workbench 15 is fixedly installed on the top surface of the base 1, and an air inlet pipe 16 is fixedly connected to the workbench 15. One end of the air inlet pipe 16 is connected to the top pipe 11. An air outlet pipe 17 is arranged on the top of the upper cover 5. A lifting plate 18 and a magnetic block 19 are fixedly installed on the top surface of the upper cover 5. The two top pipes 11 are fixedly connected to the upper cover 5 and the workbench 15 respectively, and the two semi-drying tubes 7 are fixedly connected.

[0030] like Figure 1 As shown, the top surface of the base 1 is fixedly connected to a limiting ring 20, and the size of the limiting ring 20 matches the size of the semi-drying tube 7;

[0031] By providing the limiting ring 20 , the semi-dry tube 7 can be limited.

[0032] like Figure 1 As shown, the bearing 4 is also provided with a magnetic block corresponding to the magnetic block 19, and a desiccant is placed in the semi-drying tube 7;

[0033] By providing a magnetic block corresponding to the magnetic block 19 on the bearing 4, the upper cover 5 can be limited and magnetically fixed when the upper cover 5 is turned back.

[0034] like Figure 3 As shown, the diameter of the closing plate 10 is smaller than the diameter of the fixing ring 8 , and the outer diameter of the top pipe 11 is smaller than the inner diameter of the fixing ring 8 .

[0035] By setting the diameter of the closing plate 10 smaller than the diameter of the fixing ring 8, the gas can smoothly enter the semi-dry tube 7, and by setting the outer diameter of the jacking pipe 11 smaller than the inner diameter of the fixing ring 8, the jacking pipe 11 can easily lift the closing plate 10.

[0036] like Figure 3 and Figure 4 As shown, the number of the vent holes 12 is four groups, and the vent holes 12 are distributed in a circular shape with equal distances with respect to the vertical center line of the top pipe 11;

[0037] By providing four groups of vent holes 12, the flow rate of gas can be increased.

[0038] like Figure 3 As shown, the sizes of the sealing rubber pad 13 and the sealing pad 14 are consistent with the inner wall size of the fixing ring 8;

[0039] By arranging the sizes of the sealing rubber pad 13 and the sealing pad 14 to match the inner wall size of the fixing ring 8, the sealing effect can be enhanced and the gas leakage can be reduced.

[0040] The working principle of the gas filtering and drying device provided by the utility model is as follows:

[0041] Step 1: When in use, firstly, the handle 6 is turned to screw the threaded rod 3 out of the fixed tube 2. The upper cover 5 can be lifted upward by the setting of the bearing 4, and then the lifting plate 18 is pushed to take the upper cover 5 away from the semi-dry tube 7. Then, the semi-dry tube 7 can be removed for replacement. At the same time, the upper cover 5 can be lifted and lowered to adapt to semi-dry tubes 7 of different heights and sizes.

[0042] The second step: after replacing the semi-dry tube 7, push the lifting plate 18 to rotate the magnetic block 19 to be magnetically fixed with the bearing 4, then rotate the handle 6 in the opposite direction to lower the upper cover 5, and push a group of top pipes 11 on the upper cover 5 to the closing plate 10. At the same time, when the upper cover 5 presses down the closing plate 10, the top pipe 11 on the workbench 15 pushes open another group of closing plates 10, and then rotate the handle 6 to compress the two portable replacement devices, and seal them with the sealing pad 13, so that the gas can flow from the inlet pipe 16, the top pipe 11, the semi-dry tube 7 and the outlet pipe 17, and the semi-dry tube 7 dries the gas;

[0043] The third step: when the semi-dry tube 7 needs to be replaced, the upper cover 5 is lifted, and the closing plate 10 on the semi-dry tube 7 seals and closes the semi-dry tube 7 under the action of the spring telescopic rod 9 and the sealing gasket 14, so that the semi-dry tube 7 can be quickly replaced.
