Problems solved by technology

Under the existing technical conditions, it usually relies on manual scissors to puncture the tank body to release pressure. Under the action of the internal and external pressure difference, the residual material in the pressure spray tank will spray out from the opening, and the sprayed liquid will easily hurt the operator. Great potential safety hazard and easy to cause environmental pollution

Embodiment 1

[0025] Such as figure 1 As shown, in this embodiment, a pressure relief device for a pressure spray tank includes an installation structure 1 for installing and limiting a pressure spray tank 10 and a backing plate 2 arranged in the installation structure 1. The installation structure 1 A locking device for locking the pressure spray can 10 is arranged on the top, and a destroying device for destroying the pressure spray can 10 is arranged under the backing plate 2 .

[0026] The pressure spray can 10 to be destroyed is placed inside the structure of the installation structure 1 , and the pressure spray can 10 is locked by a locking device to prevent it from detaching from the installation structure 1 . The pressure spray can 10 is destroyed from the bottom of the pressure spray can 10 by the destruction device. The installation structure 1 and the locking device can effectively limit the pressure spray can 10, avoiding the pressure spray can caused by the pressure air ejectio...

Embodiment 2

[0029] Such as figure 2 As shown, on the basis of the above embodiments, in this embodiment, the destroying device includes several hollow needle tubes 3 and a driving structure for driving the relative movement of the hollow needle tubes 3 and the pressure spray can 10 . Utilizing the hollow needle tube 3 facilitates the pressure spray tank 10 to be punctured, and the residual liquid and high-pressure gas in the pressure spray tank 10 can also be discharged through the through hole in the hollow needle tube 3, which is beneficial to uniformly collect the residue in the pressure spray tank 10, deal with.

[0030] In this embodiment, the driving structure includes a base 4 for installing the hollow needle tube 3 and an air cylinder 5 arranged under the base 4 . The cylinder 5 is used to drive the base 4 to move up and down, thereby driving the hollow needle tube 3 and the pressure spray tank 10 to move relative to each other so that the hollow needle tube 3 punctures the pres...

Embodiment 3

[0034] Such as figure 2 As shown, on the basis of the above-mentioned embodiments, in this embodiment, the base 4 is provided with several protective sleeves 7 set on the hollow needle tube 3, and a spring is arranged between the protective sleeve 7 and the base 4 8. In the process of the hollow needle tube 3 piercing the pressure spray tank 10, the hollow needle tube 3 may be bent under force, and the protective sleeve 7 can limit the bending deformation of the hollow needle tube 3 and increase the rigidity of the hollow needle tube 3, thereby helping to protect the hollow needle tube 3. shape precision. By connecting the protective cover 7 with the base 4 through the spring 8, the protective cover 7 can compress the spring 8 to adaptively adjust the position of the protective cover during the process of the hollow needle tube 3 puncturing the pressure spray tank 10, so as to avoid the protective cover 7 from piercing the pressure spray tank 10. Interfering with the breaki...

Abstract

The invention discloses a pressure spray tank pressure relief device. The pressure spray tank pressure relief device comprises a mounting structure used for mounting and limiting a pressure spray tankand a base plate arranged in the mounting structure, wherein a locking device used for locking the pressure spray tank is arranged on the mounting structure, and a destroying device used for destroying the pressure spray tank is arranged below the base plate. The pressure spray tank pressure relief device has the beneficial effects that according to the scheme, the pressure spray tank can be effectively limited by using the mounting structure, so that the situation that the pressure spray tank moves randomly and hurts people due to recoil force formed after pressure gas is sprayed out is avoided; and according to the scheme, a tank body can be damaged from the lower position when the pressure spray tank is placed, so that the pressure air is sprayed out from the lower part, then the pressure air is prevented from directly facing the personnel, and the safety performance is enhanced.

Description

technical field [0001] The invention relates to the technical field of pressure spray cans, in particular to a pressure relief device for pressure spray cans. Background technique [0002] After the pressure spray cans such as penetrants for flaw detection are used up, there will be residual pressure in the tank, which is prone to explosion and other dangers during the recovery process. Therefore, it is required that each bottle of pressure tank must be depressurized after use and can be recycled. Under the existing technical conditions, it usually relies on manual scissors to puncture the tank body to release the pressure. Under the action of the internal and external pressure difference, the residual material in the pressure spray tank will be sprayed out from the opening, and the sprayed liquid will easily hurt the operator. Great potential safety hazard and easy to cause environmental pollution. Contents of the invention [0003] In order to overcome the deficiencies...
