Description

Technical Field

[0001] The invention relates to the technical field of powder storage, and in particular to a powder storage device with a sealing detection function. Background Art

[0002] A powder storage device is a device designed to store various powdered materials. It is widely used in chemical, food processing, pharmaceutical, agricultural and other industries. It has a good seal to prevent the entry of outside air, moisture or other pollutants and maintain the quality of the powder. Therefore, its own sealing detection is very necessary for powder storage. The automated sealing detection system can monitor the powder storage status in real time, detect problems in time, and warn the staff, making maintenance work more efficient and conducive to the management of powder.

[0003] In the existing patent CN218259983U, a powder storage device is disclosed, including a storage tank body, both sides of the bottom of the storage tank body are connected with support feet, the upper left end of the storage tank body is provided with a feed port, the inlet end of the feed port is plugged with a sealing plug, the bottom of the storage tank body is provided with a discharge port, and the top of the storage tank body is provided with a support frame near the middle. The utility model is provided with a crushing motor, a crushing shaft, a coupling, a crushing blade, a limit support, an inert gas adding device, a vacuuming mechanism, a gas adding pipeline and an exhaust pipeline, and utilizes the mutual cooperation between them, so that the storage tank body can be vacuumed and inert gas can be added, which is beneficial to the long-term storage of powder. In addition, when discharging the powder in the storage tank body, the powder can be pre-crushed to prevent the powder from agglomerating into blocks and blocking the discharge port due to long storage time, which is convenient for discharging.

[0004] In the above structure, the powder can be crushed, but in the process of crushing the powder, it is difficult to realize the sealing detection of the device, it is impossible to switch the sealing detection mode, and it is impossible to match and use multiple detection modes, which is not conducive to rapid detection of the leakage position. For example, when there is a leakage in a certain place, the whole device is generally detected first, and the leakage position cannot be directly known. The whole device needs to be detected section by section to detect the exact leakage position.

[0044] Working principle: Before storing the powder, first test the sealing of the storage box 1, close the feed pipe 2 and the discharge funnel 3, so that the sealing plate 601 is located at the initial positions on both sides of the storage box 1, and test the sealing of the storage box 1 as a whole. During the sealing test, the air supply device is connected with the rotating tube 501, and the gas is introduced into the connecting block 602 through the rotating tube 501 and the air outlet 504, and the gas is introduced into the sealing airbag 605 through the air guide tube 606, so that the sealing airbag 605 is in close contact with the storage box 1, and the sealing plate 601 is further sealed to form a sealed environment, and the solenoid valve on the air guide tube 606 is closed, and the solenoid valve on the inflation nozzle 603 is opened, and the gas is continued to be introduced, so that the gas enters the sealed environment, so that the air pressure in the sealed environment is increased to the detection air pressure, and the sealing test of the storage box 1 is realized;

[0045] When a separate compression test is required, the electric push rod 1001 is started, and the output end of the electric push rod 1001 drives the connecting plate 1002 and the square rod 1003 to move to the first position, that is, the square rod 1003 is connected to the rotating rod 1 901, the square rod 1003 is separated from the rotating rod 2 902, and the active bevel gear 2 903 is separated from the forward driven bevel gear 904 and the reverse driven bevel gear 905 respectively; the driving motor 801 is started, and the output shaft of the driving motor 801 rotates to drive the active gear 802 to rotate, and the active gear 802 drives the driven gear 803 to rotate, so that one threaded rod 402 rotates, and the other threaded rod 402 does not rotate, and under the action of the guide block 404, the driving gear 802 rotates. The threaded rod 402 drives the adjusting block 403 to move, so that the adjusting block 403 drives the rotating tube 501 to move, and the rotating tube 501 drives the rotating assembly 7 and the sealing plate 601 to move, so that the sealing plate 601 is close to another sealing plate 601, and the rotating mounting block 502, the connecting block 602, the sealing airbag 605 and the inflation nozzle 603 move accordingly. Since the connecting rod 503 is hinged between the two rotating mounting blocks 502, the connecting rod 503 is forced to be compressed. When the sealing plate 601 is located at the detection position, the rotating tube 501 is connected to the air supply device, and the sealing airbag 605 and the inflation nozzle 603 are inflated in turn to detect the pressure of the sealing environment, thereby realizing a separate compression detection mode.

[0046] When bidirectional compression testing is required, the electric push rod 1001 is started, and the output end of the electric push rod 1001 drives the connecting plate 1002 and the square rod 1003 to move to the second position, that is, the square rod 1003 is connected to the rotating rod 1 901, the square rod 1003 is separated from the rotating rod 2 902, and the active bevel gear 2 903 is respectively engaged with the forward driven bevel gear 904 and the reverse driven bevel gear 905; due to the movement of the connecting plate 1002, the limit plate 1203 moves with it. When the toggle rod 1 When 202 contacts the bottom of the arc groove 1204, the arc groove 1204 causes the toggle rod 1202 to be subjected to a downward force, so that the toggle rod 1202 drives the connecting rod 1201 to move downward, so that the connecting rod 1201 drives the baffle 1103 to move downward, and the baffle 1103 moves downward to drive the support rod 1102 to move downward, and the spring 1104 is compressed, so that the support rod 1102 drives the active bevel gear 2 903 to move downward to mesh with the forward driven bevel gear 904 and the reverse driven bevel gear 905;

[0047] The driving motor 801 is started, and the output shaft of the driving motor 801 rotates to drive the driving gear 802 to rotate, and the driving gear 802 drives the driven gear 803 to rotate, so that the rotating rod 1 901 rotates forward, and the forward driven bevel gear 904 rotates forward. Under the action of the driving bevel gear 2 903, the reverse driven bevel gear 905 rotates reversely. Under the transmission action of the driving gear 802 and the driven gear 803 on the other side, the two threaded rods 402 rotate in opposite directions, so that the adjusting blocks 403 move closer to or away from each other, so that the adjusting blocks 403 drive the rotating The tube 501 moves, and the rotating tube 501 drives the rotating assembly 7 and the sealing plate 601 to move, so that the two sealing plates 601 are close to or away from each other, and the rotating mounting block 502, the connecting block 602, the sealing airbag 605 and the inflation nozzle 603 move accordingly. Since the connecting rod 503 is hinged between the two rotating mounting blocks 502, the connecting rod 503 is forced to be compressed or stretched. When the sealing plate 601 is located at the detection position, the rotating tube 501 is connected to the air supply device, and the sealing airbag 605 and the inflation nozzle 603 are inflated in turn to detect the pressure of the sealing environment, thereby realizing a two-way compression detection mode;
