[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a pressure vessel safety relief device, including:

[0035] Please see Figures 1-5 This utility model provides a technical solution:

[0036] A pressure vessel safety relief device includes a tank body 1 and a cover 2. A pressure relief assembly 4 is provided on the top of the cover 2. The pressure relief assembly 4 includes a handle 417. A vertical rod 416 is bolted to the bottom of the handle 417. A base plate 410 is bolted to the bottom of the vertical rod 416. A second spring 49 is welded to the top of the base plate 410. A first spring 48 is provided outside the second spring 49. A retaining ring 412 is welded to the top of both the first spring 48 and the second spring 49. A ring plate 414 is bolted to the bottom of the retaining ring 412. The surface of the tank 1 is inserted into the inner wall of the slot plate 413. By operating the pressure relief component 4, the gas can be easily discharged by the staff, thus achieving the purpose of safe pressure relief to a certain extent. The safety factor for the staff is good. The surface of the tank 1 is provided with a collection component 5, which includes a collection ring 52. The surface of the collection ring 52 is provided with a collection pipe 51. The bottom of the collection pipe 51 is inserted into a collection box 56. Through the collection component 5, the gas leaked from the inside of the container can be easily collected, thus protecting the working environment of the staff to a certain extent.

[0037] It is worth noting that, in order to better release the pressure, the pressure relief assembly 4 also includes a pressure relief component 418. The bottom of the pressure relief component 418 is connected to a gas pipe 42 by bolts. The top of the gas pipe 42 has a groove 47. A rubber ring 411 is fitted inside the groove 47. The gas pipe 42 is inserted into the inside of the cover 2. The surface of the pressure relief component 418 has multiple air holes 41. The rubber ring 411 ensures that the sealing inside the pressure relief component 418 is well maintained, thus facilitating the release of excess gas inside the tank 1.

[0038] Next, in order to better handle the depressurized gas, the collection assembly 5 also includes an air pump 55, a discharge port 57 is provided on the surface of the collection box 56, and a support plate 58 is provided at the bottom of the collection box 56. One end of the support plate 58 is bolted to the surface of the tank 1. Through the suction force of the air pump 55, the depressurized gas can be collected into the interior of the collection box 56, which is beneficial to better handling the depressurized gas.

[0039] Meanwhile, in order to better rotate the ring plate 414, specifically, the bottom of the cover 2 is bolted to a top plate 415, the bottom of the top plate 415 is bolted to a vertical block 43, and the bottom of the vertical block 43 is bolted to a silicone round block 44. Due to the softness of the silicone round block 44 itself, when the speed block 45 passes by, the handle 417 is vibrated, but the impact on the angle of change is small.

[0040] Furthermore, in order to stably place the tank 1, specifically, the bottom of the tank 1 has multiple support legs 3 by bolts. The number of support legs 3 is multiple and the support legs 3 are distributed in a ring shape. Through the multiple ring-shaped support legs 3, the tank 1 can be stably placed on the plane.

[0041] It is worth noting that, in order to better collect the depressurized gas, the inner wall of the collection ring 52 is provided with multiple collection holes 54, and a rubber ring 53 is provided inside the collection hole 54. The diameter of the collection hole 54 matches the diameter of the air hole 41. The surface of the rubber ring 53 is inserted into the inner wall of the air hole 41. Through the rubber ring 53, the collected gas can have a better sealing effect, so that the depressurized gas can be better collected through the collection hole 54.

[0042] Finally, in order to better control the pressure relief speed, the inner wall of the pressure relief component 418 is bolted with a locking block 45, and the top of the fixing ring 412 is bolted with a locking strip 46. Through the limiting of the locking block 45 and the locking strip 46, the outer circumference of the ring plate 414 can completely cover the area of ​​the diameter of the vent 41, thus making it easier to control the pressure relief speed.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figures 1-5 The specific usage process of the pressure vessel safety relief device of this embodiment is as follows:

[0045] 1: When using this type of pressure vessel safety pressure relief device, the device needs to be moved to a suitable position via the support leg 3. The operator can use the pressure relief component 4 to release excess gas inside the tank 1. During depressurization, the operator can open the collection component 5 so that the depressurized gas is collected inside the collection box 56 for centralized treatment.

[0046] 2: When the staff needs to release pressure, the air pipe 42 is opened at the top of the cover 2. The top of the air pipe 42 is provided with a groove 47. The inner wall of the groove 47 is fitted with a rubber ring 411. The staff can release pressure on the tank 1 through the pressure relief component 4 connected to the air pipe 42. The vertical rod 416, which is bolted to the bottom of the handle 417, is moved vertically, causing the bottom plate 410 at the bottom of the vertical rod 416 to rise. Through the force of the first spring 48 and the second spring 49, the fixing ring 412 on the surface of the vertical rod 416 rises. The rising fixing ring 412 can lift the ring plate 414. The gas rises from inside the groove plate 413. Multiple vents 41 are provided on the surface of the tank 1. When the ring plate 414 rises, the gap between the ring plates 414 contacts the inner wall of the pressure relief component 418, thus connecting with the vents 41. This facilitates the release of excess gas from inside the tank 1. The bottom of the cover 2 is provided with a top plate 415. When the top of the fixing ring 412 contacts the bottom plate 410, the first gas release is completed. Pressing the handle 417 and the vertical rod 416 at the bottom of the handle 417 again, and repeating the above operation, completes the release of excess gas. When there is a large amount of gas inside the tank 1, the working... Personnel can rotate handle 417 to make the top of the locking block 45 slide over the silicone round block 44 connected to the bottom of the vertical block 43 by bolts. At this time, the annular plate moves on the inner wall of the air hole 41. The personnel can observe the area covered by the air hole 41 on the surface of the tank body 1. The size of the covered area is helpful for the personnel to adjust the speed of the depressurized gas. When the locking block 45 is close to the surface of the locking strip 46, the position of the locking block 45 changes. Then the vertical rod 416 is raised. At this time, the depressurization lifting speed is the fastest, thus achieving the purpose of safe depressurization to a certain extent. For the personnel, the safety factor is good.

[0047] 3. When depressurization begins, the operator can start depressurizing by turning on the air pump 55. The depressurized gas will then flow through the air hole 41 into the inside of the collection ring 52. The gas will then travel along the rubber ring 53 on the inner wall of the collection hole 54 into the inside of the collection pipe 51, and finally be collected through the collection box 56 at the top of the support plate 58. This facilitates the centralized collection of gas leaking from the container and its treatment through the discharge port 57, thus protecting the working environment of the operators to a certain extent.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
