Description

Technical Field

[0001] This utility model belongs to the technical field of safe production and storage and transportation of hazardous chemicals, and in particular relates to a food-grade liquid carbon dioxide safety storage tank with a sealing structure. Background Technology

[0002] Carbon dioxide is a material frequently used in the food processing industry. Under standard conditions, the volume of a unit mass of carbon dioxide gas is hundreds of times that of liquid carbon dioxide. To facilitate the storage of more carbon dioxide using food-grade liquid carbon dioxide safety storage tanks, carbon dioxide is liquefied and stored. A sealing structure is installed at the inlet of the food-grade liquid carbon dioxide safety storage tank to prevent carbon dioxide leakage, thereby improving the safety of carbon dioxide transportation.

[0003] A search revealed a food-grade carbon dioxide storage tank in patent publication number CN211649825U. The tank includes a body and a lid, which are connected together. The body has an air inlet and a drain outlet, located at the top and bottom of the tank, respectively. The tank also includes a partition plate that divides the internal space into a first and a second accommodating space, positioned vertically. The advantages are: by dividing the tank into the first and second accommodating spaces, and by directly installing a high-pressure generating device within the first accommodating space, the low-temperature carbon dioxide gas entering the first accommodating space is liquefied under high pressure. The liquefied gas is then stored in the second accommodating space through a connecting port, thus integrating the preparation and storage of liquid carbon dioxide. This improves the practicality of the invention and reduces the overall investment in carbon dioxide gas preparation and storage.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. Existing food-grade carbon dioxide storage tanks use a cover to seal the inlet end of the tank during use, which effectively prevents carbon dioxide leakage from the inside of the tank. However, since the cover is placed inside the tank, it reduces the field of vision for the cover, which in turn makes it inconvenient to disassemble and repair the cover.

[0006] 2. Existing food-grade carbon dioxide storage tanks, during use, rotate the connecting shaft by rotating the mounting part, thereby adjusting the position of the sealing element and switching the seal at the tank inlet. This allows for switching between the positions of the first and second air inlets. However, it is not convenient to accurately align the second air inlet with the first air inlet, which can affect the introduction of carbon dioxide into the tank and even cause carbon dioxide leakage, thus hindering the effective improvement of carbon dioxide transportation safety.

[0007] To address these issues, we provide a food-grade liquid carbon dioxide safety storage tank with a sealing structure. Utility Model Content

[0008] The purpose of this utility model is to provide a food-grade liquid carbon dioxide safety storage tank with a sealing structure. By setting a sealing component and a rotation measuring component, the existing food-grade carbon dioxide storage tanks have the problems of inconvenient disassembly and maintenance of the lid and inconvenient accurate rotation and adjustment of the lid angle.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model relates to a food-grade liquid carbon dioxide safety storage tank with a sealing structure, comprising a tank body, a sealing assembly, and a rotation measuring assembly. A screw plug is threaded onto the neck of the tank body. The periphery of the neck is connected to the side wall of an ear block in the sealing assembly. A damping bearing is interference-fitted onto the periphery of a support rod connected to the ear block. A movable cover is fixed to the side wall of an ear seat rotatably connected to the periphery of the damping bearing, and the movable cover abuts against the screw plug. The side wall of the ear block is connected to the side wall of a connecting block in the rotation measuring assembly. A mounting seat is connected to a connecting rod connected to the connecting block. A pointing block fixed to the mounting seat corresponds to a scale line on the periphery of the ear seat. The mounting seat is slidably connected to a groove on the periphery of the ear seat.

[0011] The present invention is further configured such that a valve is connected to the air inlet pipe communicating with the movable cover, and an air inlet hole is provided on the screw plug.

[0012] The present invention is further provided that the handle fixed to the movable cover is fitted with an anti-slip sleeve around its periphery, and a sealing gasket is provided on the lower surface of the movable cover.

[0013] The present invention is further configured such that the side wall of the mounting seat is threadedly connected with a bolt, and the internal threaded hole opened on the inner side of the slide groove is threadedly connected to the bolt.

[0014] The present invention is further configured such that a dividing component is provided inside the tank, and a connecting pipe is connected to the lower surface of the dividing hopper in the dividing component, and the dividing hopper is sleeved on the inside of the tank.

[0015] The present invention is further configured such that a valve is connected to the periphery of the connecting pipe, and a high-pressure generator disposed above the dividing hopper is connected to the inner wall of the tank.

[0016] The present invention is further configured such that the surface of the tank body away from the neck is connected in a ring array with self-locking casters.

[0017] The present invention is further configured such that a valve is connected to the drain pipe connected to the lower periphery of the tank body, and the height of the outlet end of the drain pipe is higher than the height of the lower surface of the self-locking caster wheel.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model sets up a sealing component and adjusts the position of the air inlet pipe by rotating the movable cover, thereby achieving alignment or misalignment between the air inlet pipe and the air inlet hole, thereby achieving the sealing switch of the inlet end of the tank. Since the sealing component is placed outside the tank, the field of vision is increased, which facilitates the inspection and disassembly of the sealing component.

[0020] 2. This utility model, by setting up a rotation measuring component, determines the rotation angle of the movable cover by observing the scale line value on the ear seat pointed to by the pointing block. This allows for convenient and accurate adjustment of the air inlet pipe to align with the air inlet hole, which in turn facilitates better passage of carbon dioxide gas through the air inlet pipe and air inlet hole into the interior of the tank, effectively preventing carbon dioxide gas leakage.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0031] Please see Figure 1 and 2 This utility model is a food-grade liquid carbon dioxide safety storage tank with a sealing structure, including a screw plug 4 threadedly connected to a tank neck 102 connected to the tank body 1. A sealing assembly 2 is provided on the periphery of the tank neck 102. The sealing assembly 2 includes an ear block 201, a support rod 202, an ear seat 203, a movable cover 204, and an air inlet pipe 206. By rotating and adjusting the movable cover 204, the air inlet hole 401 on the screw plug 4 of the air inlet pipe 206 can be aligned or misaligned, thereby realizing the switching of the sealing operation at the upper end of the tank body 1. The sealing assembly 2 is external, which is convenient for maintenance or disassembly.

[0032] Specifically, a support rod 202 is connected to the lug 201 connected to the periphery of the neck 102. The support rod 202 is rotatably connected to the periphery of the damping bearing 203d, which is interference-fitted to the periphery. The lug 203 is fixed to the side wall of the movable cover 204. A valve 206a is connected to the periphery of the air inlet pipe 206 connected to the movable cover 204.

[0033] Furthermore, a sealing gasket 204a is provided on the lower surface of the movable cover 204, and an anti-slip sleeve 205a is fitted around the handle 205 connected to the movable cover 204. The inner diameter of the air inlet 401 opened on the screw plug 4 is equal to the inner diameter of the air inlet pipe 206.

[0034] The operation process of this embodiment is as follows: When an external force is applied to the handle 205 by hand, the ear seat 203 moves in an arc with the support rod 202 as the fixed point through the damping bearing 203d, which drives the movable cover 204 to rotate and drives the air inlet pipe 206 to move. When the air inlet pipe 206 is aligned with the air inlet hole 401, the valve 206a on the air inlet pipe 206 is opened to introduce carbon dioxide gas into the tank 1; otherwise, the movable cover 204 blocks the air inlet hole 401 to achieve the sealing operation of the upper port of the tank 1. Specific Implementation Example 2

[0035] Please see Figure 1 and 3 Based on the first specific embodiment, a rotation measuring component 3 is provided. The rotation measuring component 3 includes a connecting block 301, a connecting rod 302, a mounting base 303, and a pointing block 303b. This allows the operator to observe the scale value pointed to by the pointing block 303b to determine the rotation angle of the movable cover 204, thereby effectively improving the accuracy of the alignment between the air inlet pipe 206 and the air inlet hole 401, which is beneficial for the entry of gas dioxide into the interior of the tank 1.

[0036] Specifically, a connecting rod 302 is connected to the connecting block 301 connected to the side wall of the ear block 201. A pointing block 303b is connected to the mounting seat 303 connected to the connecting rod 302. The pointing block 303b points to the scale line 203c opened on the periphery of the ear seat 203. The sliding groove 203a opened on the periphery of the ear seat 203 is slidably connected to the mounting seat 303. An internal threaded hole 203b is opened on the inner side wall of the sliding groove 203a. The internal threaded hole 203b is threadedly connected to the bolt 303a threadedly connected to the mounting seat 303.

[0037] Furthermore, the groove 203a is arc-shaped, and the internal threaded hole 203b is opened in an arc-shaped path;

[0038] The operation process of this embodiment is as follows: loosen the bolt 303a clockwise, rotate the movable cover 204, and the ear seat 203 moves in an arc with the support rod 202 as the fixed point. The scale line 203c pointed to by the pointing block 303b changes until the pointing block 303b points to the designated scale line 203c. At this point, the air inlet 401 is aligned with the air inlet pipe 206. Tighten the bolt 303a counterclockwise to lock the position of the air inlet pipe 206, so that carbon dioxide gas can be added into the tank 1 through the air inlet pipe 206. Specific Implementation Example 3

[0039] Please see Figure 1 , 4Based on specific embodiments one and two, a separation component 5 is provided. The separation component 5 includes a separation hopper 501, a connecting pipe 502 and a high-pressure generator 104. By operating the high-pressure generator 104, the carbon dioxide gas entering the separation hopper 501 is pressurized and liquefied. The liquefied carbon dioxide falls into the bottom of the tank 1, which facilitates the separation of carbon dioxide in different states.

[0040] Specifically, the dividing hopper 501 is fitted inside the tank body 1, the connecting pipe 502 is connected to the lower surface of the dividing hopper 501, the high pressure generator 104 is connected to the inner wall of the tank body 1, the lower surface of the tank body 1 is connected to a self-locking universal wheel 101, and the drain pipe 103 connected to the periphery of the tank body 1 is away from the tank neck 102.

[0041] Furthermore, the self-locking casters 101 are arranged in a circular array, and there are three self-locking casters 101. Valves 206a are connected to the periphery of the drain pipe 103 and the connecting pipe 502.

[0042] The operation process of this embodiment is as follows: the high pressure generator 104 is started, which increases the pressure at the top of the separator 501, pressurizes and liquefies the carbon dioxide gas at the top of the separator 501, and the carbon dioxide liquid falls down to the bottom of the tank 1 by its own gravity. The carbon dioxide liquid collected at the bottom of the tank 1 is discharged through the drain pipe 103.
