Description

Technical Field

[0001] The utility model belongs to the technical field of tank sealing, in particular to a stainless steel tank sealing device. Background Art

[0002] Stainless steel cans are containers used to store food. They have strong corrosion resistance and are not corroded by external air or residual chlorine in water. They have good sealing properties. The sealed design completely prevents harmful substances and mosquitoes in air dust from invading the can, ensuring that the water quality is not polluted by the outside world and does not breed red worms.

[0003] When a stainless steel tank is used to hold fermented liquid, the existing sealing device can only isolate the flow between the stainless steel tank body and the outside world. When it is necessary to sample or observe the liquid inside the stainless steel tank, it is necessary to open the sealing device to detect and observe the liquid inside the stainless steel tank. This will destroy the sealing effect of the stainless steel tank and affect the liquid inside.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a sealing device which can not only seal a stainless steel tank but also sample the internal liquid without significantly affecting the sealing effect of the stainless steel tank.

[0006] To achieve the above-mentioned purpose, the utility model proposes a stainless steel tank sealing device, comprising a stainless steel tank body, a circular opening is provided on the upper surface of the stainless steel tank body, a sealing cover is threadedly connected at the circular opening, a sampling assembly is provided on the sealing cover, the sampling assembly comprises a vertical pipe, the vertical pipe passes through the sealing cover and is fixedly connected to the sealing cover, the upper surface of the sealing cover is fixedly connected to a shell, a fixed block is fixedly connected to the shell, a circular groove is provided on the fixed block, a delivery pipe is fixedly connected to the bottom of the shell, the delivery pipe is connected to the vertical pipe, the delivery pipe passes through the fixed block, the other end of the delivery pipe is connected to the circular groove, a sealing block is slidably connected in the circular groove, a circular through groove is provided on the sealing block, a circular tube is provided in the circular through groove, the circular tube can slide and rotate in the circular through groove, a sampling tube is provided at the upper end of the circular tube, and a piston is slidably connected in the sampling tube.

[0007] In one example, the circular tube passes through the shell upward, the circular tube is rotatably connected to the shell, the cross-section of the pipe in the circular tube is square, the lower end of the sampling tube is fixedly connected to the square tube, and the square tube cooperates with the square channel in the circular tube.

[0008] In one example, the inner wall of the sampling tube is fixedly connected to a transverse plate, a threaded rod is threadedly connected to the transverse plate, the lower end of the threaded rod is fixedly connected to a blocking plate, and the upper end of the threaded rod is fixedly connected to a handle.

[0009] In one example, the outer side of the circular tube is threadedly connected to a control ring, the outer side of the control ring is fixedly connected to two support rods, and the two support rods are fixedly connected to the sealing block.

[0010] In one example, the upper surface of the sealing block is fixedly connected to two guide rods, the inner wall of the shell is fixedly connected to two support plates, and the two guide rods both penetrate the support plates and are slidably connected to the support plates.

[0011] In one example, the sampling tube is made of transparent glass.

[0012] In one example, the lower end of the circular tube is located above the circular groove.

[0013] The stainless steel tank sealing device proposed by the utility model can bring the following beneficial effects:

[0014] Firstly, by arranging a sampling assembly on the sealing cover, the guide rod is pulled upward to make the sealing block slide up and expose the delivery tube. At this time, the delivery tube is connected with the outside world, and the air pressure squeezes the liquid inside. The liquid goes upward through the vertical tube and enters the circular groove through the delivery tube. The liquid pushes the air in the circular tube and enters the sampling tube together with the air. The piston slides up and then presses down to reset the sealing block, blocking the delivery tube and restoring the sealing of the stainless steel tank body. By arranging a sampling assembly on the sealing cover, the device will not affect the sealing of the stainless steel tank body during sampling. Sampling can be completed without opening the stainless steel tank body, which is more convenient.

[0015] Secondly, by threading the control ring on the round tube and rotating the sampling tube, the sampling tube drives the round tube to rotate. Since the control ring is threaded on the outer side of the round tube, the round tube controls the control ring to slide up, which makes the operation more convenient. When the round tube is reversed and the sealing block is controlled to drop and reset, the threaded groove between the round tube and the control ring can prevent the air pressure inside the stainless steel tank body from pushing the sealing block to slide up, resulting in the sealing block being unable to block the delivery pipe and destroying the sealing effect.

[0029] Specifically, the circular tube 306 penetrates the shell 302 upward, and the circular tube 306 is rotatably connected to the shell 302. The cross-section of the pipeline in the circular tube 306 is square. The lower end of the sampling tube 307 is fixedly connected to the square tube 4, and the square tube 4 cooperates with the square channel in the circular tube 306.

[0030] Specifically, the inner wall of the sampling tube 307 is fixedly connected to the transverse plate 5 , the threaded rod 6 is threadedly connected to the transverse plate 5 , the lower end of the threaded rod 6 is fixedly connected to the blocking plate 7 , and the upper end of the threaded rod 6 is fixedly connected to the handle 8 .

[0031] Specifically, the outer side of the circular tube 306 is threadedly connected to the control ring 9 , the outer side of the control ring 9 is fixedly connected to two support rods 10 , and the two support rods 10 are fixedly connected to the sealing block 305 .

[0032] Specifically, the upper surface of the sealing block 305 is fixedly connected to the two guide rods 11 , the inner wall of the housing 302 is fixedly connected to the two support plates 12 , and the two guide rods 11 both penetrate the support plates 12 and are slidably connected to the support plates 12 .

[0033] Specifically, the sampling tube 307 is made of transparent glass.

[0034] Specifically, the lower end of the circular tube 306 is located above the circular groove.

[0035] Working principle: The stainless steel tank body contains fermented liquid, such as fermented yogurt, etc. The circular opening on the top is sealed by the sealing cover 2 through threaded tightening. At this time, the vertical pipe 301 is inserted into the liquid inside the stainless steel tank body, and the lower end of the vertical pipe 301 is close to the bottom of the stainless steel tank body. When sealing, the lower surface of the sealing block 305 is tightly attached to the bottom surface of the circular groove, and the side of the sealing block 305 blocks the conveying pipe 304, so that the inside of the stainless steel tank body is in a sealed state at this time;

[0036] When it is necessary to sample and observe the liquid in the stainless steel tank body, it is necessary to pull out the sampling tube 307, rotate the threaded rod 6, and the blocking plate 7 pushes down the piston 308 to discharge the gas between the piston 308 and the sampling tube 307. The piston 308 is tightly attached to the bottom of the sampling tube 307, and then the square tube 4 is inserted into the round tube 306. At this time, the guide rod 11 is pulled upward to make the sealing block 305 slide up to expose the delivery tube 304. At this time, the delivery tube 304 is connected to the outside. Since the stainless steel tank body 1 is sealed inside and the liquid is in a fermentation state, the internal air pressure is greater than the external air pressure. The air pressure squeezes the liquid inside, and the liquid passes through the vertical pipe 30 1 upward, enters the circular groove through the delivery pipe 304, the liquid pushes the air in the circular tube 306, and enters the sampling tube 307 together with the air, and the gas and liquid push the piston 308 to slide up and enter the sampling tube 307. During the whole process, the staff holds and presses the sampling tube 307 downward to prevent the sampling tube 307 from being separated from the circular tube 306, and then presses down the sealing block 305 to reset, block the delivery pipe 304, and restore the sealing of the stainless steel tank body. The device arranges the sampling component 3 on the sealing cover 2, so that when sampling, the sealing of the stainless steel tank body will not be affected, and the sampling can be completed without opening the stainless steel tank body, which is more convenient;

[0037] After the square tube 4 at the lower end of the sampling tube 307 is inserted into the square channel in the circular tube 306, when the sealing block 305 needs to move and the delivery tube 304 needs to be opened, the sampling tube 307 is rotated at this time, and the sampling tube 307 drives the circular tube 306 to rotate. Since the outer side of the circular tube 306 is threadedly connected to the control ring 9, the circular tube 306 controls the control ring 9 to slide up, which is more convenient to operate. When the circular tube 306 is reversed and the sealing block 305 is controlled to descend and reset, the threaded groove between the circular tube 306 and the control ring 9 can prevent the air pressure inside the stainless steel tank body from pushing the sealing block 305 to slide up, resulting in the sealing block 305 being unable to block the delivery tube 304 and destroying the sealing effect. The material of the sampling tube 307 is transparent glass, and the state of the sample pushed into the sampling tube 307 can be directly observed. When inspection is required, the sampling tube 307 can be directly pulled out to push out the sample.
