Technical Field

[0001] This utility model relates to the field of storage tank technology, and in particular to a storage tank with high safety. Background Technology

[0002] Storage tanks are sealed containers used to store liquids or gases. They play an important role in the industrial, chemical, petroleum, food, and pharmaceutical industries. They are indispensable equipment for storing various raw materials, intermediate products, and finished products, and play an irreplaceable role in the development of the national economy.

[0003] With the rapid development of industrial technology, storage tanks, as key equipment for storing liquids or gases, have been widely used in the petroleum, chemical, food, and pharmaceutical industries. However, the sealing of the inlet and outlet of traditional storage tanks is not strong, which can lead to gas or liquid leakage, or allow external gases to enter the storage tank and react with the liquids and gases inside, which can easily cause danger. Utility Model Content

The top end of the tank body is provided with a feed inlet and the bottom end of the tank body is provided with a discharge outlet. The structures of the discharge outlet and the feed inlet are the same. A sealing pressure ring is provided on the top of the feed inlet.

[0007] The feed inlet includes a feed tube with an internal thread on the upper part of the inner wall. A threaded post is inserted into the feed tube and is threadedly connected to the internal thread. A connecting post is provided at the bottom of the threaded post, and a rubber piston is fixedly installed on the connecting post. The rubber piston is tightly fitted to the lower part of the inner wall of the feed tube. A knob cover is provided at the top of the threaded post, and a second sealing ring is provided at the bottom of the knob cover. The second sealing ring is tightly fitted to the first sealing ring.

[0008] Furthermore, in a preferred configuration, an annular groove is provided on the upper part of the outer wall of the feed inlet.

[0009] Furthermore, in a preferred configuration, the outer wall of the knob cover is provided with an annular groove.

[0010] Furthermore, in a preferred configuration, the annular fastener is composed of two semi-circular fasteners, both of which have identical structures, with annular rubber sheet two and annular rubber sheet one respectively provided at the top and bottom of the inner side of the semi-circular fasteners.

[0011] Furthermore, in a preferred configuration, the second shaped rubber sheet and the first annular rubber sheet are respectively fitted into the second annular groove and the first annular groove.

[0012] In addition, a preferred structure is that both ends of the semicircular fastener are provided with mounting plates, and the two semicircular fasteners are fixedly connected by bolts and nuts through the mounting plates.

[0013] In addition, a preferred structure is that the tank is equipped with a breather valve, and support frames are fixedly installed at both ends of the bottom of the tank.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, the rubber piston is in close contact with the inner wall of the feed pipe, and the sealing ring one and the sealing ring two are in close contact, which greatly enhances the sealing performance of the inlet and outlet of the tank, so that the liquid or gas inside the tank will not leak out and the external gas will not enter the tank, thus enhancing the safety of the storage tank.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A high-safety storage tank includes a tank body 1 and an annular fastener 10. A feed inlet 4 is provided at one end of the top of the tank body 1, and a discharge outlet 5 is provided at one end of the bottom of the tank body 1. The structures of the discharge outlet 5 and the feed inlet 4 are the same. A sealing pressure ring 42 is provided at the top of the feed inlet 4.

[0024] The feed inlet 4 includes a feed tube 41. The upper part of the inner wall of the feed tube 41 is provided with an internal thread 411. A threaded post 6 is threadedly inserted into the feed tube 41 and is threadedly connected to the internal thread 411. A connecting post 9 is provided at the bottom of the threaded post 6. A rubber piston 7 is fixedly installed on the connecting post 9. The rubber piston 7 is tightly fitted to the lower part of the inner wall of the feed tube 41. A knob cover 8 is provided at the top of the threaded post 6. A sealing pressure ring 2 81 is provided at the bottom of the knob cover 8. The sealing pressure ring 2 81 is tightly fitted to the sealing pressure ring 1 42.

[0025] Meanwhile, an annular groove 412 is provided on the upper part of the outer wall of the feed inlet 4.

[0026] Furthermore, an annular groove 82 is provided on the outer wall of the knob cover 8.

[0027] Meanwhile, the annular fastener 10 is composed of two semi-circular fasteners 101. The two semi-circular fasteners 101 have the same structure. The top and bottom of the inner side of the semi-circular fastener 101 are respectively provided with annular rubber sheet 2 103 and annular rubber sheet 102.

[0028] Furthermore, the second shaped rubber sheet 103 and the first annular rubber sheet 102 are respectively inserted into the second annular groove 82 and the first annular groove 412, which not only limit the knob cover 8 above the material tube 41, but also further ensure the sealing of the inlet 4 and the outlet 5.

[0029] Meanwhile, both ends of the semicircular fastener 101 are provided with mounting plates 104. The two semicircular fasteners 101 are fixedly connected by bolts and nuts through the mounting plates 104. At this time, the annular fastener 10 limits the knob cover 8 on the material tube 41.

[0030] Furthermore, a breather valve 3 is installed on the tank body 1, and support frames 2 are fixedly installed at both ends of the bottom of the tank body 1. The breather valve 3 balances the air pressure inside the tank body 1, and the support frames 2 enhance the stability of the tank body 1.

[0031] In this embodiment, by twisting the knob cover 8, the threaded post 6 is rotated and inserted into the feed tube 41. The rubber piston 7 below the threaded post 6 is in close contact with the inner wall of the feed tube 41, which initially enhances the sealing performance between the feed inlet 4 and the feed outlet 5. The sealing pressure ring 81 at the bottom of the knob cover 8 is in close contact with the sealing pressure ring 42 at the top of the feed tube 41, which further enhances the sealing performance between the feed inlet 4 and the feed outlet 5. Then, the annular rubber pieces 102 and 103 of the two semi-circular fasteners 101 are inserted into the annular slots 412 and 82, respectively. Then, the two semi-circular fasteners 101 are installed together with bolts and nuts, and the knob cover 8 and the feed tube 41 are installed together, which further enhances the sealing performance between the feed inlet 4 and the feed outlet 5, so that the gas or liquid inside the tank 1 will not leak out, and the external gas will not enter the tank 1, thus enhancing the safety of the storage tank.

[0032] When the air pressure inside tank 1 becomes unbalanced, the breather valve 3 is activated to balance the air pressure in tank 1, thereby enhancing the safety of tank 1.

[0033] In this invention, the rubber piston 7 is in close contact with the inner wall of the feed pipe 41, and the sealing ring 42 and the sealing ring 81 are in close contact, which greatly enhances the sealing performance of the inlet 4 and outlet 5 of the tank 1, so that the liquid or gas in the tank 1 will not leak out and the external gas will not enter the tank 1, thus enhancing the safety of the storage tank.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
