Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology and relates to a spiral exhaust device. Background Technology

[0002] In industries such as smelting and chemical processing, tank trucks are commonly used liquid storage devices. Fixed storage tanks and tank trucks used for transporting liquids by train or truck are generally equipped with safety venting devices on the top to promptly remove gases generated inside the tank and effectively prevent the internal pressure from increasing. Due to space constraints, the venting pipes of fixed storage tanks, trucks, and trains cannot be installed too high. However, during the transportation of hazardous liquids, when the tank truck starts, stops, brakes, or accelerates, the liquid material may overflow from the venting port due to the inertia of the transported liquid. This leakage can cause tank corrosion, injuries, and environmental pollution, posing safety risks and hindering the safe transportation of liquids. Utility Model Content

[0003] The purpose of this invention is to provide a spiral exhaust device to address the problems existing in the prior art.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A spiral exhaust device includes a tank, the top of which is provided with an exhaust port, and an exhaust pipe with a spiral structure is connected to the exhaust port. Multiple baffles are fixed inside the exhaust pipe along the length of the exhaust pipe, and the baffles are fixed to the lower part of the inner wall of the exhaust pipe. The end of the exhaust pipe away from the exhaust port forms an air outlet.

[0006] Furthermore, the exhaust pipe is composed of multiple arc-shaped pipe bodies spliced ​​together, and the baffle plate is fixed to one end of the pipe body.

[0007] Furthermore, the liquid baffle has a semi-circular structure.

[0008] Furthermore, the liquid baffle plate is provided with through holes.

[0009] Furthermore, the air outlet faces downwards.

[0010] The beneficial effects of this utility model are as follows: the spiral structure of the exhaust pipe greatly increases the length of the exhaust pipe without increasing its length, thereby extending the flow path of the solution and effectively preventing the solution from flowing out of the exhaust pipe; multiple baffles are set in the exhaust pipe to reduce the flow rate and volume of the solution in the exhaust pipe, ensuring that the solution cannot flow out; the structure is simple and the method of use is convenient.

[0014] The present invention will now be described in detail with reference to the accompanying drawings:

[0015] like Figure 1 and 2 As shown, a spiral exhaust device includes a tank 1 installed on a transport vehicle. The top of the tank 1 has an exhaust port 2, through which gas generated inside the tank 1 can be discharged. An exhaust pipe 3 with a spiral structure is connected to the exhaust port 2. Specifically, the exhaust pipe 3 is a spiral structure with two to three turns. The spiral structure greatly increases the length of the exhaust pipe 3 without increasing its height. Increasing the length of the exhaust pipe 3 extends the flow path of the solution, effectively preventing solution leakage. The exhaust pipe 3 is made of stainless steel. Specifically, the exhaust pipe 3 is constructed by welding multiple arc-shaped pipe bodies 301 together. Multiple baffles 4 are fixed inside the exhaust pipe 3 along its length. The semi-circular structure (the radius of the baffle plate 4 is the same as the radius of the exhaust pipe 3) has the baffle plate 4 fixed to the lower part of the inner wall of the exhaust pipe 3. Specifically, the number of baffle plates 4 corresponds to the number of pipe bodies 301, that is, one baffle plate 4 is fixed in each pipe body 301, and the baffle plate 4 is fixed to one end of the pipe body 301 by welding. The baffle plate 4 can slow down the flow rate and flow of the solution in the exhaust pipe 3, ensuring that the solution cannot flow out of the exhaust pipe 3. The baffle plate 4 is provided with a through hole 5, which allows the solution remaining in the exhaust pipe 3 to flow back to the tank 1 through the baffle plate 4, preventing residue from being generated in the exhaust pipe 3. In order to prevent external impurities from falling into the exhaust pipe 3, the end of the exhaust pipe 3 away from the exhaust port 2 forms a downward-facing exhaust port 6.

[0016] The working principle of this utility model is as follows:

[0017] During transportation, when the transport vehicle suddenly stops, accelerates, or experiences other situations, the liquid in tank 1 enters the exhaust pipe 3 from the exhaust port 2 under the action of inertia and flows towards the exhaust end pipe 6. During the flow in the exhaust pipe 3, it can be blocked multiple times by multiple baffles 4, which slows down the flow and flow rate of the solution, so that the flow rate and flow rate of the solution gradually decrease, and thus it cannot flow out through the exhaust pipe 3. Since the exhaust pipe 3 is relatively long, it increases the path of the solution, thereby effectively preventing the solution in tank 1 from flowing out of the exhaust pipe, without affecting normal exhaust.
