Description

Technical Field

[0001] The utility model relates to the technical field of liquefied gas raw material processing, and particularly relates to a liquefied gas raw material dryer. Background Art

[0002] Liquefied petroleum gas is a colorless volatile liquid obtained by pressurizing and cooling natural gas or petroleum in a refinery. The liquefied gas in a liquefied gas filling station usually contains a certain amount of moisture. For example, methane generally contains 35 - 120 ppm of moisture. When liquefied gas is stored and transported, it needs to be pressurized to more than 20 MPa. If it contains moisture, it is easy to condense into water in pipelines and equipment, affecting the transportation of natural gas and the operation of the filling station. Moreover, water vapor is likely to form steam of water, and the water vapor will react with components such as carbon dioxide and hydrogen sulfide in natural gas to generate corrosive products, causing corrosion to pipelines and equipment. Therefore, all filling stations must conduct deep drying treatment on natural gas;

[0003] After checking the publication number: CN220770431U, a liquefied gas raw material dryer is disclosed. In this technology, "the liquefied gas raw material dryer includes a drying cylinder and a connecting pipe. The drying cylinder is connected with an output pipe, the drying cylinder is connected with an input pipe, the input pipe and the output pipe are connected with a first flange, the connecting pipe is connected with a second flange, the first flange and the second flange are connected with a clamping mechanism. The clamping mechanism includes a vertical plate and a mounting block. The vertical plate is assembled on the surface of the second flange, an insertion block is connected to the vertical plate, the insertion block is provided with a clamping hole, the mounting block is fixedly assembled on the surface of the first flange, the mounting block is provided with a slot, the insertion block is assembled with the slot, and the mounting block is provided with an inner cavity, and the inner cavity is connected with an insertion rod" and other technical solutions, and has technical effects such as "solving the problem that when the existing flanges are installed with each other, the fastening of each bolt on the flange is different, and when liquefied gas is transported, it is easy to cause the pipelines to shake, resulting in the loosening of the bolts on the flange";

[0004] In the existing solution, liquefied gas is stored in the drying cylinder, and the liquefied gas is transported through the input pipe and the output pipe. The flange on the pipeline of the drying cylinder itself and the connecting flange are fixed by bolts. Due to the installation between the flanges, the fastening of each bolt on the flange is different. When liquefied gas is transported, it is easy to cause the pipelines to shake, resulting in the loosening of the bolts on the flange, affecting the airtightness of liquefied gas transportation; moreover, the connection method in the above solution is fixed by a spring. However, the spring may fail due to reasons such as material fatigue, corrosion, or improper use under long-term working conditions, resulting in the loosening or leakage of the pipeline connection.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: A liquefied gas raw material dryer, including a dryer, a fixing mechanism is arranged on the dryer and is used for connecting and fixing the dryer and the conveying pipeline. The fixing mechanism includes:

[0007] A connection component, including a feed pipe fixed on one side of the upper end of the dryer, a connection part integrally formed at the outer end of the feed pipe, and four fixing holes equally divided and opened on the connection part;

[0008] A reinforcement component, including a conveying pipe installed on the feed pipe, a reinforcement part integrally formed at the end of the conveying pipe, four shaft seats integrally formed equally divided on the reinforcement part, a shaft sleeve rotatably installed on the outer wall of the shaft seat, a gear fixed on the outer wall of the shaft sleeve, a threaded pin slidably installed through the inside of the shaft seat, and the outer wall of the threaded pin is threadedly connected to the inner wall of the shaft sleeve, and a gear ring rotatably installed on the reinforcement part.

[0013] Preferably, a discharge pipe is arranged at the lower end of the dryer, and a heating pipe is arranged at the lower end inside the dryer.

[0014] Beneficial effects

[0015] The utility model provides a liquefied gas raw material dryer. Compared with the prior art, it has the following beneficial effects:

[0016] When the reinforcement part on the conveying pipe and the connection part on the feed pipe are inserted and installed, rotating the hand wheel drives the gear ring to rotate.
