Technical Field
[0001] The utility model relates to the technical field of pressure relief devices, in particular to a pressure relief device for a pressure container. Background Art
[0002] In some chemical fields, pressure vessels are used. Pressure vessels are mainly used to store some gases or liquids. Pressure vessels have good sealing properties, so a large pressure may be generated inside them. The pressure needs to be released, so a pressure relief device for the pressure vessel is needed.
[0003] The pressure vessel will shake during the pressure release process, causing the connecting pipes at the joints to easily fall off, and the liquid inside will leak and be difficult to clean. In addition, as the liquid expands due to rising temperature, when the liquid expands due to heat, the distance between its molecules increases, and the molecular vibration energy increases, thereby causing the internal pressure to rise. The existing pressure relief device does not have a cooling function, and the liquid temperature cannot drop quickly, resulting in poor use effect and low efficiency of the pressure release device. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.
[0020] Combined with Figure 1 , Figure 2 , a pressure relief device for a pressure vessel, comprising a workbench 1 and a container body 2, wherein the container body 2 is located on the workbench 1, and anti-shake structures are provided on both sides of the workbench 1, wherein the anti-shake structure comprises a vertical plate 3, a motor 4 located on the vertical plate 3, a screw 5 connected to an output end of the motor 4, a sleeve 6 threadedly connected to the screw 5, a positioning plate 7 connected to the sleeve 6, and a limiting member located between the vertical plate 3 and the positioning plate 7, wherein the vertical plate 3 is located at the upper edge of the workbench 1, and the motor 4 is located on a side of the vertical plates 3 that are away from each other, wherein the limiting member comprises two symmetrically arranged telescopic rods 8 and a spring 9 sleeved on the telescopic rods 8, wherein the two ends of the telescopic rod 8 are respectively connected to the vertical plate 3 and the positioning plate 7, and the two ends of the spring 9 are respectively connected to the vertical plate 3 and the positioning plate 7, and the sides of the positioning plates 7 that are close to each other are provided with protective pads 16.
[0021] Combined with Figure 1 , Figure 3 A cooling component is provided under the workbench 1, and the cooling component includes a box body 10, a fan 11 located in the box body 10, and air outlets 12 located on both sides of the box body 10.

Support legs 14 are provided at the four corners under the box body 10, and bottom plates 15 are provided under the support legs 14.
[0022] During the specific implementation of the utility model, the container body is first placed on the workbench, and then the motor is started to drive the screw to rotate. Since a telescopic rod is connected between the vertical plate and the fixed plate, under the limit of the telescopic rod, the screw drives the sleeve to move, and the sleeve pushes the positioning plate until the positioning plate clamps the container body and positions it, thereby avoiding the situation where the connecting pipe falls off and liquid leaks due to large vibration of the pressure container during pressure release. During the pressure release process, the fan is started and rotated, and air flows in from the air outlet and is then blown out through the air outlet on the workbench to cool the pressure container, thereby accelerating the cooling of the liquid inside it and improving the pressure release efficiency.
