As shown in fig. 3, the design of the anti-drop ring 4 mainly aims at disassembling the inner tank 2 and the outer tank 1, when the anti-drop ring 4 is assembled, the inner tank 2 is inserted into the inner tank 2 in a state where the anti-drop ring 4 is not assembled until the inner tank 2 is assembled, and then the anti-drop ring 4 is assembled on the outer tank 1 through a fastener, the sealing ring 6 mainly aims at sealing between the inner tank 2 and the outer tank 1 to avoid leakage, and the sealing ring in the technical scheme can be replaced and maintained along with the disassembly of the anti-drop ring 4, and the additional explanation is that the anti-drop ring 4 needs to be assembled and fixed when the inner tank 2 just enters the outer tank 1, so that the inner tank 2 can form a negative pressure state in a closed space formed by the outer wall of the inner tank 2, the inner wall of the outer tank 1 and the anti-drop ring 4 when the inner tank 2 and the anti-drop ring 4 are assembled, and the inner wall of the inner tank 2 can be firmly attached to the outer tank 1 after the inner tank 2 and the anti-drop ring 4 are assembled, and the raw material permeation performance is prevented from being increased when the inner tank 1 is assembled, and the raw material permeation performance is prevented from being increased.

As shown in fig. 4, a hemispherical and hollow tail tank 3 is fixedly welded at the bottom of the outer tank 1, the inner diameter of the tail tank 3 is smaller than the inner diameter of the anti-drop ring 4, a protruding portion between the tail tank 3 and the bottom of the outer tank 1 is used as a stress supporting component, a downward arc chamfer is formed at the inner side of the protruding portion, and the downward arc chamfer mainly serves to enable raw materials stored in the inner tank to flow smoothly into the tail tank 3 when the inner tank 2 moves downward, and particularly the raw materials scraped from the inner wall of the outer tank 1 can be transferred and used.

As shown in fig. 2, the bottom of the inner tank 2 is integrally fixedly welded with a stress ring 7, the stress ring 7 is sleeved on the outer ring of the inner tank 2, the bottom of the stress ring 7 is in a blade shape as shown in fig. 5 and is in extrusion contact with the inner part of the outer tank 1, when raw materials are filled into the explosion-proof tank, particularly as shown in fig. 1, after the inner cavity of the explosion-proof tank is filled, the filling can be continued, the inner tank 2 is gradually moved upwards due to the increase of raw materials and internal pressure along with the increase of the filling raw materials, on one hand, the storage capacity of the whole explosion-proof tank can be increased, and on the other hand, the pressure balance inside the self-adaptive explosion-proof pipe can be additionally described, and the problem that the explosion-proof tank is in an idle natural balance state when the raw materials are filled, namely, the problem that the explosion-proof tank is crushed due to the large pressure difference generated when the internal raw materials are pumped away in the later stage is avoided, and the action of upward movement of the inner tank 2 is mostly caused by the internal change of the force; when the raw materials of the inside storage of explosion-proof jar are used, along with the reduction of raw materials, the inside can produce negative pressure state, produce decurrent appeal, pull inner tank 2 downwardly, with the negative pressure state that the inside of balanced explosion-proof jar produced because the raw materials is shifted, inner tank 2 is when the downwardly moving, be the atress ring 7 of blade form and do the action of "shovel" all the time along the inner wall of outer jar 1, can be with remaining and adhering the thing shovel down on the outer jar 1 inside, accomplish when storing raw materials not extravagant, still can play the effect of clean outer jar 1 inner wall.

The outer ring of the inner tank 2 is sleeved with a spring 8, the bottom of the spring 8 is lapped at the top position of the stress ring 7, the top of the spring 8 is in contact with the bottom of the sealing ring 6, and in an idle state as shown in fig. 1, the spring 8 is in a compressed state, namely, two ends of the spring 8 are respectively applied to the stress ring 7, namely the inner tank 2 and the sealing ring 6, and the force applied to the stress ring 7 can be matched with the action of the negative pressure generated when the raw materials in the explosion-proof tank are pulled away to assist in pulling the inner tank 2 downwards to balance the internal pressure of the explosion-proof tank, and the force applied to the sealing ring 6 can squeeze the sealing ring 6 to generate a certain degree of deformation, so that the sealing ring is better adhered to the outer wall of the inner tank 2, and the problem of sealing leakage is solved; meanwhile, the spring 8 is also in contact with the outer wall of the inner tank 2 and the inner wall of the outer tank 1, so that when the spring 8 stretches out and draws back, attachments carried by the outer wall of the inner tank 2 due to long-time exposure in the outside air can be treated, each time the inner tank 2 moves up and down in a cleaning treatment process, the problem that an explosion-proof tank is corroded due to long-time exposure can be effectively relieved, and when the spring 8 stretches out and draws back, the wires of the spring 8 are subjected to cutting action to cut off some adhesives, and the adhesives have two parts, wherein one part is the materials on the inner side of the outer tank 1 are stored for a long time and adhered on the inner wall of the outer tank 1, and the other part is the adhesives produced by the long-time storage of the inner tank 2 due to exposure in the outside, so that the obstacles on the up and down movement of the inner tank 2 are avoided.

In the present embodiment

1. Firstly, assembling and mounting, the operation is most convenient under the lying state, the anti-drop ring 4 with the sealing ring 6 is sleeved on the outer ring of the inner tank 2, the spring 8 is sleeved on the outer ring of the inner tank 2 and is propped against the anti-drop ring 4, then the port part of the inner tank 2 is inserted into the port position of the outer tank 1, and then the anti-drop ring 4 is pushed, the inner tank 2 is driven to extend into the inner cavity of the outer tank 1 by utilizing the friction force between the sealing ring 6 and the outer wall of the inner tank 2, and the extra care is needed, the inner tank 2 is not required to be penetrated into the limit position, a certain distance is reserved, the anti-drop ring 4 is fixedly mounted at the port position of the outer tank 1 by a fastener, and the inner tank 2 is gradually driven to the limit position along with the gradual attachment and fixation of the anti-drop ring 4;

2. after the assembly is completed, the state is shown in fig. 1, at this time, the internal pressure of the whole explosion-proof tank is balanced, raw material filling is carried out from the top of the inner tank 2 into the inner cavity of the explosion-proof tank, when the raw material enters, the internal pressure can change, when the pressure reaches the limit due to filling, the inner tank 2 is pushed upwards to move upwards so as to relieve the change of the internal pressure, and meanwhile, the capacity of the explosion-proof tank can be further increased along with the movement of the inner tank 2, and the explosion-proof tank can be used after the filling is completed. When the anti-explosion device is used, the anti-explosion device can be divided into two cases of raw material use and normal storage, when the raw material is used normally, as the raw material storage amount in the anti-explosion tank is reduced, negative pressure is generated in the anti-explosion tank, the inner tank 2 gradually moves downwards under the action of the negative pressure and the reverse acting force of the spring 8 so as to balance the pressure in the anti-explosion tank, and the problems that the anti-explosion tank is easy to be deformed or even damaged due to the negative pressure generated by the consumption of the internal raw material in the use can be effectively solved; the other is that the explosion-proof tank is needed to be used for storage, when the explosion-proof tank is used for storage, raw materials and air inside the explosion-proof tank are subjected to linkage influence due to the influence of external environment, such as exposure or low temperature, expansion or shrinkage can occur, wherein the expansion is easy to cause the explosion-proof tank to be expanded or deformed, the inner tank 2 can be pushed to extend out of the inner cavity of the outer tank 1 more deeply due to the fact that the internal pressure is further increased so as to compensate and balance the internal pressure difference of the explosion-proof tank, and when the internal pressure is reduced, the inner tank 2 automatically moves reversely so as to balance the internal pressure difference of the explosion-proof tank;

3. when the inner tank 2 moves out of the outer tank 1, the stress ring 7 moves upwards to squeeze the spring 8 to generate compression action, the compression of the spring 8 can generate extrusion force on the stress ring 7 and the sealing ring 6, and the sealing ring 6 can deform to a certain extent after receiving the extrusion force, so that the inner ring of the sealing ring 6 can be better attached to the outer wall of the inner tank 2, and the tightness is further improved; when the inner tank 2 is recycled and enters the inner cavity of the outer tank 1, on one hand, the pressure in the explosion-proof tank is small to generate suction force, on the other hand, the spring 8 can also provide pushing force to help the inner tank 2 to carry out recycling action, and when the inner tank 2 stretches out and is recycled and enters the inner cavity of the outer tank 1, the spring 8 repeatedly stretches out and draws back, so that adherents attached to the outer wall of the inner tank 2 and the inner wall of the outer tank 1 can be scraped and pinched off, and the corrosion resistance of the explosion-proof tank is improved;

4. in the process of recycling the inner tank 2, the knife-edge-shaped stress ring 7 is always attached to the inner wall of the outer tank 1 and moves in a spade state, so that raw materials or other substances adhered to the inner wall of the outer tank 1 can be shoveled off in the moving process, different raw materials can be conveniently loaded by cleaning the inner wall, and residual raw materials can be scraped off and taken out for use as far as possible, so that the problem of raw material waste is solved;

5. during maintenance work, in a vertical state, an operator first removes the anti-drop ring 4 through crane equipment, then withdraws the inner tank 2 and each structure on the inner tank, and replaces the spring 8 and the sealing ring 6 which are used for a certain time.
