Abstract
The invention relates to a blasting device for a low-temperature liquid storage tank, which has the advantages of simple structure, easy disassembly and assembly, convenient cleaning and safe use. The blasting device is composed of a blasting device, wherein a sealing cap in the blasting device is communicated with a connection pipe through a flange and a fastener, which forms a storage compartment for blasting pieces; meanwhile, a blasting piece storage inlet is communicated with one of the four ports of a four-way valve, another port opposite to one port of the four-way valve is communicated with one end of the blasting device, the other end of the blasting device is communicated with a pressure tube, and a mesh is adopted to insulate the opposite ports of the four ports. The invention has the advantages that: the structure is simple; the device is disassembled and cleaned easily, the device is horizontally installed downwards, which can avoid freezing of blasting pieces after raining and subsequent failures; internal meshes are set and are capable of avoiding damages caused by flying blasting pieces to ensure the safety of surrounding equipment and personnel for better safety; and the storage compartment for blasting pieces can be used for storing the blasting pieces conveniently.
Description
Technical field
The present invention relates to a kind of simple in structure, dismounting is easy to clean, use the blasting device for low-temperature liquid storage tank of safety, belong to cryogenic liquid tank and make the field with safety device.
Background technology
CN2388179Y, title " safety guard that a kind of cryogenic liquid tank is used "; this device comprises tee ball valve, safety valve, explosion-proof apparatus and drain valve; two ports of export of described tee ball valve are connected to respectively a four-way connection, and described safety valve, explosion-proof apparatus, drain valve are connected on respectively on other three interfaces of four-way connection.Its weak point: the one, complex structure, explosion-proof effect is poor, can't guarantee personnel's and property safety on every side; The 2nd, dismounting cleaning inconvenience; The 3rd, need often to change safety valve and antiriot device, maintenance cost is high.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of simple in structure, dismounting is easy to clean, use the blasting device for low-temperature liquid storage tank of safety.
Design: to achieve these goals.1, sealing cap is communicated with the design that consists of rupture disk fragment storage compartment by flange and securing member with adapter, is one of technical characterictic of the present invention.The purpose of makeing like this is: the one, and adopt one in sealing cap, flange, adapter and the four-way to connect and mouthful be communicated with, not only can be split into a withstand voltage storehouse, and this withstand voltage storehouse can be deposited and filled the fragment that the explosion of demolition set borehole blasting sheet produces; The 2nd, adopt flange fastener to connect sealing cap and adapter, the impulsive force that produces in the time of not only can effectively bearing explosion, and be easy to dismounting and cleaning.2, logical relative gas outlet, both sides adopt the net barrier from design, be two of technical characterictic of the present invention.The purpose of doing like this is: the net barrier from, not only effectively prevent equipment around having gone out, guaranteed of rupture disk fragment and people's safety, and adopt the gas outlet, two ends, satisfied the gas outlet area requirements.
Technical scheme: blasting device for low-temperature liquid storage tank, it comprises demolition set, sealing cap in the described demolition set is communicated with adapter by flange and securing member and consists of rupture disk fragment storage compartment and rupture disk fragment and deposit import and be communicated with a port in the four-way, another relative with a port in four-way port is communicated with demolition set one end, the demolition set other end is communicated with force pipe, relative two side ports in the four-way adopt the net barrier from.
The present invention compares with background technology, and the one, simple in structure; The 2nd, the dismounting cleaning is convenient; The 3rd, the downward installation of level can prevent that rupture disk from drenching with rain and freeze and lost efficacy; The 4th, in establish separation net, can prevent effectively that the rupture disk fragment from going out the equipment that produces around harm and the protection and people's safety, use safer; The 5th, rupture disk fragment storage compartment can be deposited the fragment of dress rupture disk easily.
Description of drawings
Fig. 1 is the structural representation of blasting device for low-temperature liquid storage tank.
Fig. 2 be among Fig. 1 A to structural representation.
The specific embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.Blasting device for low-temperature liquid storage tank, it comprises demolition set, sealing cap 1 in the described demolition set by flange and securing member 2 with take over 3 and be communicated with formation rupture disk fragment storage compartment and rupture disk fragment and deposit import and be communicated with a port in the four-way, another relative with a port in four-way port is communicated with demolition set 6 one ends, demolition set 6 other ends are communicated with force pipe, and relative two side ports in the four-way 4 adopt 5 isolation of net grid.Two side ports (gas outlet) adopt the net barrier from, can prevent effectively that the rupture disk fragment from going out the equipment that produces around harm and the protection and people's safety.Single area of working off one's feeling vent one's spleen for fear of reducing because of the net grid adopts the gas outlet, two ends simultaneously, has satisfied the gas outlet area requirements.
Described demolition set is comprised of rupture disk and clamper, and purpose is that the rupture disk fragment storage compartment that consists of can be deposited the fragment that fills rupture disk, adopts simultaneously flange arrangement, and it is convenient to be easy to the cleaning of folding dress.
Described demolition set 6 other ends are communicated with force pipe by flange and securing member 7.
Because of the characteristic of top cryogenic gas, during installation, should be the downward installation of level and can prevent that rupture disk from drenching with rain and freeze and lost efficacy.
What need to understand is: although above-described embodiment is to the present invention's detailed text description of contrasting; but these text descriptions; just the simple text of mentality of designing of the present invention is described; rather than to the restriction of invention mentality of designing; any combination, increase or modification that does not exceed mentality of designing of the present invention all falls within the scope of protection of the present invention.
Claims (3)
