DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1 and Figure 2 As shown, the embodiment of the present utility model provides a barium sulfate powder selection device, comprising:

[0028] Base 1;

[0029] The filter element 2 is rotatably mounted on the base 1 and has a feed port 207 for feeding materials; and

[0030] The swing assembly includes a gear 4 that is rotatably arranged on the base 1 and connected to the filter element 2, and a driving member arranged on the side of the base 1. The driving member is connected to the gear 4 for driving the gear 4 to rotate back and forth on the base 1, thereby driving the filter element 2 to swing back and forth in the base 1.

[0031] In an embodiment of the present invention, the end of the filter element 2 has a feed port 207 for feeding materials, and barium sulfate powder can be put into the filter element 2 through the feed port 207. The filter element 2 has a plurality of filter holes. The barium sulfate powder with a particle size smaller than the filter hole will be collected by the filter element 2, while the barium sulfate powder with a particle size larger than the filter hole will remain in the filter element 2 and be processed again later. In order to avoid the barium sulfate powder remaining in the filter element 2 from clogging the filter holes, the filter element 2 is rotatably arranged inside the base 1, so with the cooperation of the swing component, the gear 4 can be driven by the driving member to rotate back and forth on the base 1, so that the gear 4 drives the filter element 2 to swing back and forth in the base 1, so that the barium sulfate powder in the filter element 2 is always in an active state, which can effectively prevent the barium sulfate powder from clogging the filter holes during the filtration process, thereby improving the screening efficiency, reducing the number of manual interventions, and making the entire screening process smoother.

[0032] Based on the above scheme, if Figure 3As shown, the driving component includes a motor 3 arranged on the side of the base 1, a turntable 301 arranged on the output shaft of the motor 3, and a rack 401 slidably arranged on the side of the base 1 and engaged with the gear 4. The rack 401 is fixed with a driving frame 303, and the turntable 301 is provided with a pin shaft 302, which is slidably arranged on the driving frame 303.

[0033] Specifically, when the filter element 2 is driven by the driving member, the motor 3 is started so that the output shaft of the motor 3 drives the turntable 301 to rotate, thereby causing the pin 302 on the turntable 301 to make a circular motion with the turntable 301 as the axis. When the pin 302 moves to the highest point and the lowest point of the turntable 301, the pin 302 just moves to the highest point and the lowest point of the driving frame 303, so that the filter element 2 is driven by the driving member. Figure 3 For example, when the turntable 301 rotates counterclockwise and drives the pin 302 to move to the left, the pin 302 moves in the driving frame 303 and drives the driving frame 303 to move to the left until the pin 302 moves to the bottom of the driving frame 303. When the turntable 301 continues to rotate, the turntable 301 drives the pin 302 to move to the right, thereby causing the pin 302 to drive the driving frame 303 to move to the right. Repeating the above steps can achieve the turntable 301 continuously rotating and driving the rack 401 to reciprocate left and right. Since the rack 401 is engaged with the gear 4, when the rack 401 reciprocates, it can drive the gear 4 to rotate reciprocally, thereby causing the filter element 2 to reciprocate, keeping the barium sulfate powder in the filter element 2 always in a moving state.

[0034] Specifically, such as Figure 1 As shown, a limiting groove 101 is provided on the side of the base 1, and a limiting block 402 is provided on the rack 401, which is slidably engaged with the limiting groove 101; under the action of the limiting groove 101 and the limiting block 402, the movement trajectory of the rack 401 can be limited to ensure that it always moves along the length direction of the limiting groove 101, thereby ensuring the reciprocating motion of the rack 401.

[0035] Based on the above scheme, if Figure 2 As shown, the filter element 2 includes a limit plate 201 and a filter cartridge 202 rotatably arranged on both sides of the base 1, the filter cartridge 202 is rotatably connected to the limit plate 201, and the filter cartridge 202 has a plurality of filter surfaces. The limit plate 201 is provided with a fixing part, and the fixing part is clamped to the filter cartridge 202 to fix the filter surface.

[0036] When selecting barium sulfate powder, particle size is an important consideration. In different usage scenarios, the particle size control size of the barium sulfate powder is also different. The diameters of the filter surfaces of the filter cartridge 202 are different, so that different filter surfaces can be used to select barium sulfate powder of different particle sizes. The diameters of adjacent filter surfaces gradually increase. After the barium sulfate powder is filtered through the filter surface with the smallest pore size, the filter cartridge 202 can be rotated so that the filter cartridge 202 rotates between the base 1 and the limit plate 201, thereby replacing the downward filter surface, thereby changing the pore size used for filtration. In this way, barium sulfate powder of different particle sizes can be selected for subsequent use or reprocessing.

[0037] In order to ensure the stability of the filter cartridge 202 after adjustment, the fixing part includes a mounting bracket 203 arranged on the limit plate 201 and a block 206 slidably arranged in the mounting bracket 203. The filter cartridge 202 is provided with a plurality of slots 209 corresponding to a plurality of filter surfaces. The block 206 is engaged in one of the slots 209. In the initial state, the block 206 is engaged in the corresponding slot 209. When adjusting the filter cartridge 202, first separate the block 206 from the corresponding slot 209 to quickly release the limit on the filter cartridge 202, and rotate the filter cartridge 202 until the block 206 is engaged in the next slot 209, thereby ensuring the stability of the filter cartridge 202 after adjustment.

[0038] Specifically, the mounting frame 203 is provided with a pull rod 204, the pull rod 204 is connected to the block 206, and the pull rod 204 is provided with a spring 205, which abuts between the block 206 and the mounting frame 203; under the action of the spring 205, it can be ensured that the block 206 is always subjected to an extrusion force, ensuring the stability of the block 206 being connected to the slot 209, and when adjusting the block 206, it is only necessary to pull the pull rod 204, which is convenient to operate.

[0039] Specifically, such as Figure 1 As shown, baffles 208 are fixed between adjacent filter surfaces. Under the action of the baffles 208, each filter surface can be blocked to ensure that the barium sulfate powder carried by the filter element 2 will not enter the adjacent filter surface when it rotates back and forth, thereby ensuring the quality of barium sulfate powder processing.

[0040] Specifically, such as Figure 1As shown, the base 1 is provided with a receiving plate 5 located at the bottom end of the filtering surface. Under the action of the receiving plate 5, the filtered barium sulfate powder can be received, which is convenient for receiving with tools. Moreover, both side edges of the receiving plate 5 are provided with limiting strips 501, and a discharge port 502 for discharging is formed, which can prevent the barium sulfate powder on the receiving plate 5 from spilling from the edge of the receiving plate 5, and facilitate the material receiving under the action of the discharge port 502; moreover, the receiving plate 5 is tilted on the base 1 so that the discharge port 502 is tilted downward. The tilted receiving plate 5 can make the barium sulfate powder it carries be discharged through the discharge port 502 by its own gravity, without the need for manual intervention, saving time and effort.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
