[0026] Specifically, an opening is provided on one side of the upper tank body 1, and the screen frame includes a mounting plate 2 embedded in the opening, on which a plurality of first magnetic bars 21 are provided in parallel along the axial direction, and on the plurality of first magnetic bars 21 are provided in parallel along the longitudinal direction, and the plurality of first magnetic bars 21 and the second magnetic bars 22 form a screen pattern in the vertical direction; a handle 23 is provided on the outer side wall of the mounting plate 2.

[0027] A stepped surface is provided at the lower end of the opening for supporting the mounting plate 2, a hook 20 is provided on one side of the mounting plate 2, and a hanging buckle 12 is provided at a position corresponding to the hook 20 on the upper tank body 1. The hook 20 is connected to the hanging buckle 12 so as to connect and fix the mounting plate 2 on the upper tank body 1.

[0028] A bracket 13 is provided on the upper tank body 1, and a linear motor 50 is provided on the bracket 13. A horizontally extending fixed rod 53 is provided at the output end of the linear motor 50, and the extended end of the fixed rod 53 is inserted into the upper tank body 1. The inserted end of the fixed rod 53 is fixedly connected to a flat trumpet-shaped blowing nozzle 5, and the air inlet end of the blowing nozzle 5 is connected to a guide pipe 52. One side of the guide pipe 52 is horizontally extended out of the upper tank body 1, and the outgoing end of the guide pipe 52 is connected to a wind pipe 51 connected to a fan (not marked), and the air outlet of the blowing nozzle 5 is obliquely downward to the screen frame.

[0029] A buffer sleeve 32 is provided on the insertion end of the pull rod 31 ; a limit plate 33 is also provided on the pull rod 31 , and a fixing bolt 34 threadedly connected to the outer side of the lower tank body 14 is passed through the limit plate 33 .

[0030] The inner cavity of the upper tank body 1 is a circular cavity, and the inner cavity of the lower tank body 14 is a square cavity. In the projection direction, an inscribed pattern is formed between the circular cavity and the square cavity, that is, the cavity wall of the circular cavity is inscribed in the cavity wall of the square cavity.

[0031] Sealing rings 6 are provided at the positions of the upper tank body 1 corresponding to the insertion of the fixing rod 53 and the guide tube 52 , and at the positions of the lower tank body 14 corresponding to the insertion of the pull rod 31 .

[0032] The operating principle of this utility model is as follows:

[0033] like Figures 1 to 4 As shown, when in use, the electromagnet 4 is turned on, and at the same time, the medicine powder flows to the feed port 10 through the air compressor (not shown) and enters the upper tank body 1. The medicine powder falls from top to bottom in the upper tank body 1. During the falling process, it first passes through the sieve frame position. Since the magnetic rods are magnetic, when the medicine powder passes through the sieve structure formed by multiple first magnetic rods 21 and second magnetic rods 22 in the vertical direction, the metal impurities contained in the medicine powder will be magnetically adsorbed on the magnetic rods. In addition, the overlapping state of the first magnetic rod 21 and the second magnetic rod 22 increases the range of vertical magnetic adsorption, which is convenient for fully magnetically adsorbing impurities.

[0034] The powder passing through the sieve frame continues to fall onto the inclined connecting plate 3. The connecting plate 3 is also magnetic under the influence of the electromagnet 4, and can continue to adsorb the metal impurities remaining in the falling powder. Since the connecting plate 3 is in an inclined state, the powder continues to fall along the upper end surface of the connecting plate 3 to the lower part of the lower tank body 14 under the action of gravity, and is finally discharged and collected through the discharge port 11.

[0035] After the powder is fed, turn on the fan connected to the blowing nozzle 5, and at the same time turn on the linear motor 50, synchronously drive the air duct 51 and the blowing nozzle 5 to move horizontally in the upper tank body 1 to blow off the residual powder on the magnetic rod. The air outlet pressure should be less than the magnetic force of the magnetic rod, and it should be adjusted and set in place before use. The flat structure of the blowing nozzle, coupled with the staggered and stacked structure of the magnetic rods, is convenient for returning the wind direction in multiple directions, thereby increasing the range of the blowing. Since the powder particles are very small, they are easily driven by the flowing air and fall from the arc surface of the magnetic rod, thereby reducing the setting of the air outlet and simplifying the structure. After the blowing nozzle 5 is translated into place in the upper tank body 1, start the linear motor 50 to drive the blowing nozzle 5 back to its position and standby.

[0036] The remaining powder blown off also falls onto the magnetic connecting plate 3 and continues to be adsorbed. The powder directly falls along the slope to the discharge port 11 at the bottom of the lower tank body 14 for output.

[0037] Finally, the pull rod 31 is pulled back and forth to form an impact on the connecting plate 3. The connecting plate 3 vibrates due to the impact, which can shake out the residual powder on the connecting plate 3 and output it from the discharge port 11. Among them, the limit plate 33 moves back and forth along the screw direction in the space between the nut of the fixing bolt 34 and the outer wall of the lower tank body 14. At the same time, it also forms a limiting effect on the pull rod 31 to prevent the pull rod 31 from falling out, and the limit plate 33 can be fitted with the nut or the outer wall of the lower tank body 14 as a limit for adjusting the use angle of the connecting plate 3, which is also convenient for observing the connecting plate 3. The fitting condition of the connecting plate 3 is used to judge the change in the use angle and adjust it in time; if the use angle of the pull rod 31 needs to be fixed, a short screw fixing bolt 34 is used. At this time, the limit plate 33 is used as a pad, and the fixing bolt 34 is riveted on the lower tank body 14. When the pull rod 31 needs to be moved, the fixing bolt 34 of the short screw is loosened; at this point, the powder is filtered by the sieve frame and the electromagnetic adsorption of the connecting plate 3 can fully eliminate the metal impurities in the powder, and can also collect the powder remaining in the upper tank body 1 and the lower tank body 14, reducing the loss of powder.

[0038] Among them, since an inscribed pattern is formed between the circular cavity and the square cavity, that is, the cavity wall of the circular cavity is inscribed in the cavity wall of the square cavity, the connecting plate 3 is set to be a rectangular plate that is adapted to the shape of the inner cavity of the lower tank body 143. In this way, under the premise of avoiding the interference between the connecting plate 3 and the inner cavity wall of the lower tank body 14 due to flipping, the metal impurities that are missed at the two layers of magnetic rods on the screen frame and fall onto the connecting plate 3 can also be completely adsorbed, thereby making up for the problem of blind spots in the circular cavity of the upper tank body 1.

[0039] It should be noted that the electromagnet 4 is provided with an external wire ( Figure 1 The position shown by the dotted line on one side of the middle electromagnet 4 is left with enough length of wire in the lower tank body 14 to ensure that when the connecting plate 3 is flipped, the wire will not be driven to move at the position where it is inserted on the wall of the lower tank body 14, and the wire is located below the connecting plate 3, so as not to block the powder from falling and forming powder residue; similarly, the guide tube 52 is also set to be long enough, and the air duct 51 is kept on the outside of the upper tank body 1. Of course, a sealing ring 6 is also provided at the position where the external wire is inserted in the lower tank body 14.

[0040] After use, turn off the electromagnet 4, release the hook 20 and the hook 12, hold the handle 23 and drag out the mounting plate 2, that is, take out the first magnetic rod 21 and the second magnetic rod 22 from the upper tank body 1, and clean up the adsorbed metal impurities. At this time, if there is still powder residue on the magnetic rod, use a brush to clean and collect it and pour it into the collection container at the discharge port 11; in addition, the connecting plate 3 without electromagnetic influence loses its magnetism, and the metal impurities on the connecting plate 3 are in a loose state. Then pull the pull rod 31 to hit the connecting plate 3, and shake off the metal impurities on the connecting plate 3 to the discharge port 11 for discharge and collection. Among them, the buffer sleeve 32 on the pull rod 31 reduces the noise and reduces the impact strength on the connecting plate 3, thereby avoiding local deformation of the connecting plate 3 and affecting use.

[0041] After cleaning, place the first magnetic bar 21 and the second magnetic bar 22 into the upper tank body 1. At this time, the mounting plate 2 is placed on the lower step surface of the opening of the upper tank body 1, and the hook 20 is then hooked and connected to the hook 12. In order to ensure the stability of the connection, hooks 20 are set at the left and right ends of the mounting plate 2 to be hooked and connected to the hook 12.

[0042] Among them, such as Figure 3 As shown, the mounting plate 2 is set to half the length of the circumferential direction of the upper tank body 1. While ensuring that the length of the magnetic rod avoids interference with the inner wall of the upper tank body 1 during movement, it also ensures that the magnetic rod is of sufficient length inside the upper tank body 1, ensuring sufficient magnetic adsorption cross-sectional area.
