Description

Technical Field

[0001] The utility model relates to the technical field of vertical storage tanks, in particular to a decompression type vertical storage tank. Background Art

[0002] Vertical storage tanks are a type of material storage container widely used in many industries such as petroleum, chemical, rubber, pesticide, dye, medicine and food. According to their functional characteristics, vertical storage tanks can be divided into two types: atmospheric pressure storage tanks and pressure storage tanks. In order to ensure the safety of vertical storage tanks during material storage, a pressure reducing valve is usually installed on the top of the tank to give the tank a pressure reducing performance. The function of the pressure reducing valve is that when the internal pressure of the tank exceeds the set value, it can automatically open and release part of the pressure to prevent safety accidents caused by excessive pressure. This design makes vertical storage tanks more stable and reliable when storing various materials, effectively ensuring production safety.

[0003] In order to operate the pressure reducing valve on the top of the vertical storage tank, the staff usually need to climb to the top of the storage tank. Therefore, it is necessary to install a ladder fixed on the surface of the vertical storage tank. However, since the vertical storage tank and the ladder are fixedly connected, this brings some inconveniences during transportation. When transporting the vertical storage tank, the ladder fixed on the surface can easily come into contact with surrounding objects, thereby causing unnecessary squeezing or scratching on the surface of the vertical storage tank, which may not only affect the aesthetics of the storage tank, but also pose a potential threat to its structural safety. Therefore, how to ensure that the staff can safely operate the pressure reducing valve while avoiding damage to the storage tank caused by the ladder during transportation has become a problem that needs to be solved urgently.

[0004] Therefore, it is necessary to provide a new decompression type vertical storage tank to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a decompression type vertical storage tank.

[0006] The utility model provides a pressure-reducing vertical storage tank comprising: a storage tank body, a pressure-reducing valve, a movable ladder, a connecting seat, an arrowhead block, a clamping installation shell and an annular block, wherein the upper surface of the storage tank body is fixedly connected with the pressure-reducing valve, a movable ladder is arranged on one side of the storage tank body, a connecting seat is symmetrically fixedly connected with the surface of the storage tank body, an arrowhead block is slidably installed on the inner wall of a rectangular groove of the connecting seat, a clamping installation shell is fixedly connected with the top of the arrowhead block, and four annular blocks are symmetrically fixedly connected with the surface of a round rod of the movable ladder.

[0007] Place the mobile ladder close to the connecting seat on the surface of the tank body, insert the arrow block into the connecting seat, rotate the clamping mechanism inside the clamping installation shell, and the clamping mechanism contacts the round rod between the two annular blocks to firmly connect the tank body and the mobile ladder. The staff climbs the mobile ladder to move to the top of the tank body and drive the pressure reducing valve.

[0011] Rotate the first driving block, and the first driving block drives the bidirectional screw rod to rotate on the inner wall of the clamping mounting shell. The threaded surface of the bidirectional screw rod contacts the inner wall of the circular groove of the clamping rod, driving the clamping rods to approach each other, driving the extrusion groove to be close to the surface of the round rod between the two annular blocks, limiting the clamping rod, connecting the mobile ladder and the clamping mounting shell, and rotating the first driving block in the opposite direction, driving the clamping rods to move away from each other, and the extrusion groove no longer clamps the surface of the round rod of the mobile ladder, so that the mobile ladder and the storage tank body are separated conveniently.

[0013] Move the ladder close to the tank body, driving the arrow block to enter the rectangular groove of the connecting seat. The arrow block squeezes the buckle block to enter the inner wall of the slide groove. The buckle block squeezes the spring to contract. When the arrow block is close to the inner wall of the rectangular groove of the connecting seat, the spring resets and opens, moving the buckle block out of the slide groove, limiting the arrow block, and firmly connecting the connecting seat and the arrow block.

The threaded surface of the one-way screw contacts the inner wall of the circular groove of the moving block, driving the moving block to approach the buckle block, and squeeze the buckle block into the slide groove, so as to facilitate the separation of the arrow block and the connecting seat. When the moving block moves, the guide block slides along the inner wall of the guide groove to ensure that the moving block will not deviate when it moves.

[0016] Preferably, the extrusion groove is designed to be arc-shaped.

[0017] Ensure that the inner wall of the extrusion groove is in close contact with the surface of the round rod of the mobile ladder. When the mobile ladder is clamped firmly, at the same time, when the two round rods of the mobile ladder are clamped, the clamping rod cannot rotate, so that the mobile ladder and the tank body are connected firmly.

[0018] Preferably, the movable ladder is made of aluminum alloy.

[0019] Aluminum alloy material has high physical strength and is light in weight. After the mobile ladder is used for a long time, the surface of the mobile ladder will not be easily worn, thus extending the service life of the mobile ladder.
