Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to a stainless steel tank sealing device. Background Technology

[0002] In food processing, bio-fermentation, and chemical storage, stainless steel tanks are widely used for liquid storage due to their corrosion resistance and sealing properties. A good seal effectively isolates the liquid inside the tank from the outside air. In existing technologies, the sealing devices for stainless steel tanks typically employ structures such as flange covers, threaded plugs, or rubber sealing rings, achieving complete isolation between the tank and the external environment through physical compression.

[0003] While existing sealing devices can achieve static sealing between the tank and the external environment, when users need to observe the state of the fermentation liquid inside the tank or need to extract a small amount of sample for physicochemical and microbiological index testing, the existing sealing devices must be fully or partially opened.

[0004] This process inevitably disrupts the original sealing of the tank, exposing the internal environment to the outside air. Pollutants such as oxygen, dust, and bacteria in the air can easily enter the tank, contaminating the fermentation liquid that was originally in a relatively sterile or specific environment. This may lead to fermentation failure, product spoilage, flavor deterioration, or the production of harmful substances. At the same time, opening the tank for sampling will seriously disrupt the gas balance inside the tank, affecting the activity of microorganisms and the fermentation process. Utility Model Content

[0005] In view of the above-mentioned problem that the existing method requires opening the lid to take samples each time, which disrupts the sealed environment inside the tank, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a stainless steel tank sealing device, which aims to achieve sampling without opening the lid, and to achieve sampling while sealing without damaging the sealed environment.

[0007] To solve the above technical problems, the present invention provides the following technical solution: a stainless steel tank sealing device, including a tank body and a tank cover installed at the tank opening of the tank body, a through hole is provided at the center of the top of the tank cover, a sealing component is fixed at the top of the tank body and directly opposite the through hole, and a pump component is detachably installed at the end of the sealing component away from the tank cover.

[0008] The pump assembly includes a fixed plate, and a first electric push rod is installed at the center of the top of the fixed plate. The movable end of the first electric push rod is fixedly connected to an installation cylinder, and the pump body is detachably installed inside the installation cylinder.

[0009] As an improved technical solution, the sealing assembly includes a fixed tube welded to the position of the can cover opposite the through hole, a first ball valve fixed to a section of the fixed tube away from the can cover, a buffer tube installed at the end of the first ball valve away from the fixed tube, a second ball valve fixed to the end of the buffer tube away from the first ball valve, and a connecting tube fixed to the end of the second ball valve away from the buffer tube.

[0010] As an improved technical solution, the pump body includes a suction cylinder that is detachably installed inside the mounting cylinder, and a liquid intake port is provided at the end of the suction cylinder away from the first electric push rod. A piston is provided inside the suction cylinder, and a T-shaped pull rod is fixed at the center of the end of the piston away from the liquid intake port. An end cap is installed at the top of the suction cylinder.

[0011] As an improved technical solution, a negative pressure port is provided on the top of the fixed plate, a negative pressure pipe is welded to the fixed plate at the position opposite the negative pressure port, and lifting lugs are welded to both sides of the top of the fixed plate.

[0012] As an improved technical solution, a second electric push rod is installed at the upper position inside the mounting cylinder via a ring frame. An electromagnet is installed at the movable end of the second electric push rod. A magnetic block is embedded at the end of the T-shaped pull rod near the second electric push rod, and the magnetic block and the electromagnet are magnetically attracted to each other.

[0013] As an improved technical solution, a first connecting ring is sleeved on the end of the mounting cylinder near the suction cylinder, and a second connecting ring is fixed on the end of the suction cylinder away from the magnetic block. A threaded hole is opened on the outer edge of both the first and second connecting rings, and a locking bolt is threaded between the two corresponding threaded holes.

This utility model allows the suction cylinder to be detachably installed at the bottom of the mounting cylinder via a threaded installation method, which facilitates the installation and disassembly of the suction cylinder, and makes it convenient for unloading, maintenance and replacement.

[0016] 2. This utility model uses a vacuum pump and a negative pressure tube to pump out the air inside the buffer tube, making the inside of the buffer tube a vacuum state, thus preventing residual gas inside the buffer tube from entering the tank body and disrupting the fermentation environment.

[0017] 3. This utility model, through a dedicated sealed sampling interface and in conjunction with a built-in sampling mechanism, ensures that the tank body remains sealed during liquid sampling, preventing external contaminants from entering and changes in internal environmental parameters. At the same time, in non-sampling states, the channel automatically remains completely sealed, significantly reducing the risk of sampling contamination. Attached Figure Description

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a stainless steel tank sealing device. This stainless steel tank sealing device includes a tank body 1 and a tank cover 2 installed at the tank opening of the tank body 1. The tank body 1 and the tank cover 2 are fixed together by a flange. A through hole is provided at the center of the top of the tank cover 2. A sealing component 3 is fixed at the top of the tank body 1 and at the position directly opposite the through hole. A pumping component 4 is detachably installed at the end of the sealing component 3 away from the tank cover 2.

[0028] The pump assembly 4 includes a fixed plate 10, a first electric push rod 11 is installed at the center of the top of the fixed plate 10, and the movable end of the first electric push rod 11 is located below the first electric push rod 11. The movable end of the first electric push rod 11 is fixedly connected to a mounting cylinder 13, and the pump body 14 is detachably installed inside the mounting cylinder 13.

[0029] The sealing assembly 3 includes a fixed tube 5 welded to the position of the can cover 2 opposite the through hole. A first ball valve 6 is fixed to a section of the fixed tube 5 away from the can cover 2. A buffer tube 7 is installed at the end of the first ball valve 6 away from the fixed tube 5. A second ball valve 8 is fixed to the end of the buffer tube 7 away from the first ball valve 6. A connecting tube 9 is fixed to the end of the second ball valve 8 away from the buffer tube 7. The connecting tube 9 is connected to the fixed plate 10 through a flange.

[0030] The pump body 14 includes a suction cylinder 143 that is detachably installed inside the mounting cylinder 13. The suction cylinder 143 has a liquid intake port at one end away from the first electric push rod 11. A piston 144 is installed inside the suction cylinder 143. A T-shaped pull rod 145 is fixed at the center of the piston 144 at the end away from the liquid intake port. An end cap is installed at the top of the suction cylinder 143, and a sliding hole for the T-shaped pull rod 145 to pass through is opened at the center of the end cap.

[0031] During use, the dedicated sealed sampling interface, in conjunction with the built-in sampling mechanism, ensures that the tank body 1 remains sealed during liquid sampling, preventing external contaminants from entering and changes in internal environmental parameters. At the same time, the channel automatically remains completely sealed when not sampling, significantly reducing the risk of sampling contamination.

[0032] Example 2

[0033] Reference Figures 3-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a negative pressure port is provided on the top of the fixed plate 10, and a negative pressure pipe 12 is welded to the fixed plate 10 directly opposite the negative pressure port. The negative pressure pipe 12 is connected to a vacuum pump through a pipe. Lifting lugs are welded to both sides of the top of the fixed plate 10. Through the cooperation of the vacuum pump and the negative pressure pipe 12, the air inside the buffer tube 7 is pumped out, so that the inside of the buffer tube 7 is in a vacuum state, so as to prevent the residual gas inside the buffer tube 7 from entering the interior of the tank body 1 and destroying the fermentation environment.

[0034] A second electric push rod 141 is installed at the upper part of the inside of the mounting cylinder 13 via a ring frame. An electromagnet 142 is installed at the movable end of the second electric push rod 141. A magnetic block 146 is embedded at one end of the T-shaped pull rod 145 near the second electric push rod 141, and the magnetic block 146 and the electromagnet 142 are magnetically attracted to each other.

[0035] The first connecting ring 147 is sleeved on one end of the mounting cylinder 13 near the suction cylinder 143, and the second connecting ring 148 is fixed on the other end of the suction cylinder 143 away from the magnetic block 146. A threaded hole is opened on the outer edge of both the first connecting ring 147 and the second connecting ring 148, and a locking bolt is threaded between the two corresponding threaded holes. The mounting cylinder 13 will block the second connecting ring 148 to prevent the suction cylinder 143 from being excessively inserted into the interior of the mounting cylinder 13.

[0036] During use, the locking bolts are screwed into the corresponding two threaded holes to fix the first connecting ring 147 and the second connecting ring 148. This allows the suction cylinder 143 to be detachably installed at the bottom of the mounting cylinder 13 via threaded installation, making it easy to install and remove the suction cylinder 143 for use, and facilitating unloading, maintenance, and replacement.

[0037] The remaining structure is the same as that in Example 1.

[0038] Based on embodiments 1-2, the working principle of this utility model is as follows: The process of installing the suction cylinder 143 on the mounting cylinder 13 is as follows: insert the head end of the suction cylinder 143 into the interior of the mounting cylinder 13, align the threaded holes on the first connecting ring 147 and the second connecting ring 148, and screw the locking bolt into the corresponding two threaded holes to achieve the fixation between the first connecting ring 147 and the second connecting ring 148;

[0039] The second electric push rod 141 extends to drive the electromagnet 142 to move toward the liquid suction cylinder 143. Under the action of the electromagnet 142 and the magnetic block 146, the piston 144 is pushed toward the inside of the liquid suction cylinder 143. After pushing the threshold, the electromagnet 142 and the magnetic block 146 are magnetically attracted.

[0040] Open the second ball valve 8 and insert the mounting cylinder 13 into the buffer tube 7. At this time, seal and fix the connecting tube 9 to the fixing plate 10.

[0041] Open the first ball valve 6, and the first electric push rod 11 drives the mounting cylinder 13 to move into the tank body 1 through the valve hole of the first ball valve 6. When the sampling end of the suction cylinder 143 contacts the liquid surface inside the tank body 1, the second electric push rod 141 shortens and, under the magnetic attraction of the electromagnet 142 and the magnetic block 146, pulls the piston 144 upward. Through the negative pressure suction, the liquid inside the tank body 1 is pumped into the suction cylinder 143 for storage. After the liquid is taken, the first electric push rod 11 shortens and moves the pump body 14 into the buffer tube 7. Then, close the first ball valve 6 to block the connection between the tank body 1 and the buffer tube 7. At this time, the pump assembly 4 is detached from the connecting pipe 9, and the solution is taken out from the suction cylinder 143. During the liquid taking process, the tank body 1 is kept sealed. Liquid is taken without destroying the sealed environment to ensure the balance of the internal environment of the tank body 1.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
