Description

Technical Field

[0001] This utility model relates to the field of steel-lined plastic storage tank technology, and more specifically, to a steel-lined plastic storage tank with a pipe-mouth sealing structure. Background Technology

[0002] Steel-lined plastic storage tanks combine a metal structure with a plastic liner, integrating the strength of steel with the corrosion resistance of plastic. They are widely used in industries such as chemical, pharmaceutical, and food processing. These tanks can withstand high mechanical loads and effectively resist chemical corrosion, making them particularly suitable for storing highly corrosive liquids or solids. However, some drawbacks exist in practical use. For example, the sealing at the loading and unloading ports of existing steel-lined plastic storage tanks is not high enough, leaving tiny gaps that allow outside air to enter and react with the internal materials, affecting storage efficiency.

[0003] Therefore, a steel-lined plastic storage tank with a pipe-mouth sealing structure was proposed to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steel-lined plastic storage tank with a pipe-sealing structure to solve the problem that the sealing performance of the pipe opening of the prior art steel-lined plastic storage tank is not high enough, and there will be a small gap when it is closed, so that the outside air can enter the steel-lined plastic storage tank and react with the internal materials.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a steel-lined plastic storage tank with a pipe-mouth sealing structure, comprising...

[0006] Steel-lined plastic storage tank body;

[0007] A sealing assembly is disposed on top of the main body of the steel-lined plastic storage tank;

[0008] The sealing assembly includes a tube body, a hollow sleeve, an air bladder ring, a tube plug, a pressure plate, threads, and a knob. The bottom end of the tube body is fixedly connected to the top of the main body of the steel-lined plastic storage tank. The hollow sleeve is fixedly installed inside the tube body. The bottom of the air bladder ring is fixedly connected to the top of the hollow sleeve. The bottom of the tube plug is connected to the internal threads of the hollow sleeve. The threads are formed at the bottom of the tube plug and inside the hollow sleeve to connect the two. The pressure plate is fixedly installed in the middle of the tube plug and contacts the air bladder ring. The knob is fixedly installed on the top of the tube plug.

[0009] It also includes a shock-absorbing component, the top of which is detachably connected to a fixed base at the bottom of the steel-lined plastic storage tank body.

[0010] The damping assembly includes a base plate, a damper, a sliding block, a groove, a connecting rod, a rotating shaft, a connecting column, a top plate, and a telescopic rod. The damper is fixedly installed on the top of the base plate. One side of the sliding block is fixedly connected to one end of the damper. The groove is formed on the top of the base plate. The bottom of the sliding block is slidably connected to the inside of the groove. One end of the connecting rod is rotatably connected to the outer surface of the sliding block through a rotating shaft. The bottom end of the connecting column is rotatably connected to the other end of the connecting rod through a rotating shaft. The outer surface of the connecting column is slidably connected to the inside of the top plate.

[0011] The shock-absorbing assembly also includes a telescopic rod, the top of which is fixedly connected to the bottom of the top plate, and the bottom of which is fixedly connected to the top of the bottom plate.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] In the above scheme, a steel-lined plastic storage tank body and a sealing assembly are set up. After the material is added into the steel-lined plastic storage tank body through the pipe, the pipe plug is screwed into the hollow sleeve by turning the knob until the pressure plate presses on the air bladder ring and applies pressure to the air bladder ring, thereby deforming the air bladder ring and blocking the gaps at the edge of the pipe body. Through the above structure, the gaps at the pipe opening are sealed to prevent air from entering the interior of the steel-lined plastic storage tank body and reacting with the material inside the steel-lined plastic storage tank body, thereby affecting the quality of the material.

[0014] When the steel-lined plastic storage tank is subjected to bumps during transportation, the connecting column slides downwards. At this time, the connecting column drives the sliding block to slide in the groove through the connecting rod, thereby applying an impact force to the damper. The damper absorbs the impact force and causes the sliding block to slide back in the groove. The connecting rod then returns the connecting column to its initial position, completing the shock absorption. Through the above structure, the impact of bumps during the transportation of the steel-lined plastic storage tank is reduced, and the adverse effects of severe bumps on the internal materials are avoided.

The bottom end of the pipe body 21 is fixedly connected to the top of the steel-lined plastic storage tank body 1. The hollow sleeve 22 is fixedly installed inside the pipe body 21. The bottom of the air bladder ring 23 is fixedly connected to the top of the hollow sleeve 22. The bottom of the pipe plug 24 is threadedly connected to the inside of the hollow sleeve 22. The thread 26 is formed at the bottom of the pipe plug 24 and inside the hollow sleeve 22 to connect the two. The pressure plate 25 is fixedly installed in the middle of the pipe plug 24 and contacts the air bladder ring 23. The knob 27 is fixedly installed on the top of the pipe plug 24.

[0027] It also includes a shock-absorbing component 3, the top of which is detachably connected to the fixing seat at the bottom of the steel-lined plastic storage tank body 1.

[0028] The damping component 3 includes a base plate 31, a damper 32, a sliding block 33, a groove 34, a connecting rod 35, a rotating shaft 36, a connecting column 37, a top plate 38, and a telescopic rod 39. The damper 32 is fixedly installed on the top of the base plate 31. One side of the sliding block 33 is fixedly connected to one end of the damper 32. The groove 34 is opened on the top of the base plate 31. The bottom of the sliding block 33 is slidably connected to the inside of the groove 34.

[0030] The telescopic rod 39 can be passively extended and retracted freely to support both sides of the top plate 38 and improve stability.

[0031] The working process of this utility model is as follows: After the material is added into the steel-lined plastic storage tank body 1 through the pipe body 21, the pipe plug 24 is screwed into the hollow sleeve 22 by rotating the knob 27 until the pressure plate 25 presses on the airbag ring 23 and applies pressure to the airbag ring 23, thereby deforming the airbag ring 23 and blocking the gap at the edge of the pipe body 21.

[0032] When the main body of the steel-lined plastic storage tank 1 is subjected to bumps during transportation, the connecting column 37 will slide downward in 28. At this time, the connecting column 37 will drive the sliding block 33 to slide in the slide groove 34 through the connecting rod 35, thereby applying an impact force to the damper 32. The damper 32 will absorb the impact force and cause the sliding block 33 to slide back in the slide groove 34, and through the connecting rod 35, the connecting column 37 will return to the initial position, thus completing the shock absorption.
