Description

Technical Field

[0001] The utility model relates to the technical field of barium sulfate detection equipment, in particular to a device for detecting the particle size of barium sulfate powder. Background Technique

[0002] The mineral of barium sulfate is called barite. It is a white amorphous powder. It has stable properties and is insoluble in water, acids, alkalis or organic solvents. Barium sulfate is used in radiological examinations, mainly using its function of absorbing X-rays in the gastrointestinal tract to produce imaging. Therefore, it is mainly used as a gastrointestinal contrast agent and can also be used to manufacture barium salts, etc. Although barium sulfate is widely used in medical and industrial applications, its safety still needs to be noted. When handling barium sulfate powder, appropriate protective equipment (such as gloves, goggles and masks) should be worn to prevent skin contact and inhalation of dust.

[0003] There is a device for detecting the particle size of barium sulfate powder with the publication number CN213749498U. It is provided with a first water tank, a second water tank, a conduit, a water pump, a water pipe and a nozzle. The height difference between the first water tank and the second water tank is [X] meters, and the water pump is used to transport the water in the first water tank into the water pipe and spray it out from the nozzle to wash the barium sulfate placed on the standard test sieve. However, when separating the barium sulfate with water, the barium sulfate easily blocks the filter screen for filtering water, making the separated water unable to drain out.

[0004] Therefore, a device for detecting the particle size of barium sulfate powder is proposed. Content of the Utility Model

The output end of the servo motor is fixedly connected with a rotating shaft. The output end of the rotating shaft is fixedly connected with a circular plate. The top of the circular plate is fixedly connected with bumps arranged in an equidistant circular arrangement.

[0009] Further, one side of the bump is arranged as a slope surface, and the diameter of the circular plate is smaller than the diameter of the water collecting bucket.

[0010] Further, a limiting groove is opened at the bottom of the circular plate. Fixed rods arranged in an equidistant circular arrangement are fixedly connected to the inner bottom end of the water collecting bucket. The output end of the fixed rod is movably connected inside the limiting groove.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The water pumping mechanism of the present utility model starts to pump the water source inside the storage tank and sprays it into the inside of the standard test sieve through a high-pressure nozzle, causing the barium sulfate powder inside the standard test sieve to fall downward and be discharged through the first discharge pipe. The spraying assembly drives the high-pressure nozzle to move back and forth on the top of the standard test sieve to achieve a comprehensive cleaning of the barium sulfate powder inside the standard test sieve. The water with barium sulfate powder is conveyed into the inside of the separation sieve through the first discharge pipe.

The rotating shaft drives the circular plate to rotate. The circular plate rotates under the roller. Since one side of the convex block is set as a slope, the roller will drive the connecting rod to drop downward after being located at the top of the convex block through the slope setting of the convex block, causing the connecting rod to move up and down, and also making the separation sieve in a vibrating state. The barium sulfate powder blocking the inside of the filter screen is shaken out through the vibration of the separation sieve, and then the inside of the filter screen will not be blocked by barium sulfate powder.

[0026] Such as Figures 1 to 5As shown in the figure, a device for detecting the particle size of barium sulfate powder includes a base 1. The base 1 is a rectangular plate, and a moving component 2 is arranged at the bottom of the base 1. Four support rods 3 are fixedly connected to the left side of the top of the base 1. The top of the support rods 3 is fixedly connected to a workbench 301. A standard test sieve 302 is fixedly connected to the right side of the top of the workbench 301. A first discharge pipe 303 is fixedly connected to the right side of the standard test sieve 302. A support leg 4 is fixedly connected to the left side of the top of the workbench 301. A water storage tank 401 is fixedly connected to the top of the support leg 4. A water pumping mechanism 402 is fixedly connected to the inside of the water storage tank 401. The output end of the water pumping mechanism 402 is fixedly connected to a high-pressure spray head 403. The high-pressure spray head 403 is located above the standard test sieve 302. A spraying component 5 for driving the high-pressure spray head 403 to reciprocate is arranged on the top of the workbench 301. A water collecting bucket 6 is arranged on the right side of the top of the base 1. A second discharge pipe 602 is fixedly connected to the right side of the water collecting bucket 6. A valve 601 is fixedly connected to the top of the second discharge pipe 602. A separation sieve 7 is arranged on the top of the water collecting bucket 6. The separation sieve 7 is located at the bottom of the first discharge pipe 303. A filter screen 701 is arranged at the inner bottom end of the separation sieve 7. A vibration component 8 for driving the separation sieve 7 to vibrate is arranged on the top of the water collecting bucket 6.

[0027] It should be noted that when the water pumping mechanism 402 is started, it pumps the water inside the water storage tank 401 and sprays it into the standard test sieve 302 through the high-pressure spray head 403, causing the barium sulfate powder inside the standard test sieve 302 to fall downward and be discharged through the first discharge pipe 303. The spraying component 5 drives the high-pressure spray head 403 to move back and forth above the standard test sieve 302 to achieve a comprehensive cleaning of the barium sulfate powder inside the standard test sieve 302. The water with barium sulfate powder is transported into the separation sieve 7 through the first discharge pipe 303. The filter screen 701 separates the barium sulfate powder, and the separated water is transported into the water collecting bucket 6 through the filter screen 701 and discharged outward through the second discharge pipe 602. The vibration component 8 drives the separation sieve 7 to vibrate on the top of the water collecting bucket 6 to prevent blockage inside the filter screen 701 caused by the barium sulfate powder, avoiding the problem that the separated water cannot be discharged.

[0028] The vibration component 8 includes a fixed frame 801 fixedly connected to the right side of the top of the base 1. The bottom of the separation sieve 7 is fixedly connected with connecting rods 802 arranged in an equidistant circular arrangement. The output end of the connecting rod 802 is movably connected to the bottom of the fixed frame 801. The output end of the connecting rod 802 is fixedly connected with a roller 803. An electric motor waterproof housing 804 is arranged inside the water collecting bucket 6. A servo motor 805 is placed inside the electric motor waterproof housing 804. The output end of the servo motor 805 is fixedly connected with a rotating shaft 806. The output end of the rotating shaft 806 is fixedly connected with a circular plate 807. The top of the circular plate 807 is fixedly connected with protrusions 808 arranged in an equidistant circular arrangement. The positions of the protrusions 808 correspond to those of the rollers 803.

[0029] It should be noted that when the filter screen 701 is blocked due to barium sulfate inside, the external controller starts, the servo motor 805 starts and drives the rotating shaft 806 to rotate through the output end. The rotating shaft 806 drives the circular plate 807 to rotate. The circular plate 807 rotates at the bottom of the roller 803. Since one side of the convex block 808 is provided with a slope, the roller 803 will drive the connecting rod 802 to fall downward after being located at the top of the convex block 808 through the slope of the convex block 808, causing the connecting rod 802 to move up and down, and also making the separating sieve in a vibrating state. The barium sulfate powder blocking the inside of the filter screen 701 is shaken out through the vibration of the separating sieve 7, so that the inside of the filter screen 701 will not be blocked by the barium sulfate powder.

[0030] The spraying assembly 5 includes rectangular grooves 501 opened on the left and right sides of the standard test sieve 302. A stepping motor 502 is fixedly connected to the outer wall surface of the left rectangular groove 501. The output end of the stepping motor 502 is fixedly connected to a threaded rod 503. A sliding rod 504 is fixedly connected between the right rectangular grooves 501. A movable block 505 is threadedly connected to the outer wall surface of the threaded rod 503. The movable block 505 is movably connected to the outer wall surface of the sliding rod 504. The tops of the movable blocks 505 are fixedly connected to the bottoms of the high-pressure nozzles 403.

[0031] It should be noted that when the external controller starts, the stepping motor 502 drives the threaded rod 503 to rotate forward or backward through the output end. The threaded rod 503 drives the high-pressure nozzle 403 to move forward or backward on the top of the standard test sieve 302 through the movable block 505. The high-pressure nozzle 403 is movably connected to the outer wall surface of the sliding rod 504 through the movable block 505 on the other side, which limits the movement track of the high-pressure nozzle 403. By reciprocating movement of the high-pressure nozzle 403 on the top of the standard test sieve 302, the barium sulfate powder inside the standard test sieve 302 is washed out of the inside of the standard test sieve 302.

[0032] The moving assembly 2 includes through grooves 201 opened around the bottom of the base 1. A hydraulic rod 202 is fixedly connected to the inner bottom end of the through groove 201. The output end of the hydraulic rod 202 is fixedly connected to a wheel 203.

[0033] It should be noted that when the device needs to be moved, the hydraulic rod 202 starts. The hydraulic rod 202 drives the wheel 203 to move downward through the output end until the wheel 203 is on the ground, and the position of the device can be moved through the wheel 203.

[0034] A limiting groove 9 is opened at the bottom of the circular plate 807. Fixed rods 901 arranged in an equidistant circular arrangement are fixedly connected to the inner bottom end of the water collecting bucket 6. The output ends of the fixed rods 901 are movably connected to the inside of the limiting groove 9.

[0035] It should be noted that when the circular plate 807 moves, the circular plate 807 drives the limiting groove 9 to rotate on the top of the fixed rod 901. The fixed rod 901 strengthens the supporting force of the circular plate 807 and prevents the roller 803 from moving up and down at the bottom of the circular plate 807, which may cause the circular plate 807 to tilt.

[0036] In summary: The water pumping mechanism 402 starts to pump the water inside the water storage tank 401 and sprays it into the standard test sieve 302 through the high-pressure nozzle 403, causing the barium sulfate powder inside the standard test sieve 302 to fall downward and be discharged through the first discharge pipe 303. The spraying assembly 5 drives the high-pressure nozzle 403 to move back and forth on the top of the standard test sieve 302 to achieve a comprehensive cleaning of the barium sulfate powder inside the standard test sieve 302. The water with barium sulfate powder is conveyed into the separation sieve 7 through the first discharge pipe 303. The filter screen 701 separates the barium sulfate powder, and the separated water is conveyed into the inside of the water collecting bucket 6 through the filter screen 701 and discharged outward through the second discharge pipe 602. The vibration assembly 8 drives the separation sieve 7 to vibrate on the top of the water collecting bucket 6 to prevent the filter screen 701 from being blocked by the barium sulfate powder, which may cause the problem that the separated water cannot be discharged.
