[0026] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0027] As described in the background technology, a zinc powder feeder; zinc powder is fed to one place in the reactor, and the contact uniformity between zinc powder and the material in the reactor is poor; the anti-caking scraper is prone to blockage when feeding zinc powder, and the zinc powder agglomeration breaking effect needs to be further improved.

[0028] In order to solve this technical problem, the utility model provides a zinc powder feeder, which is used for feeding zinc powder.

[0029] Specifically, please refer to Figure 1-4 The zinc powder feeder specifically includes: a reactor 1, a spreading wheel 2 rotatably installed on the top of the reactor 1, a first motor 3 that provides power for the rotation of the spreading wheel 2, and a screw conveyor. The screw conveyor is fixedly installed on the top of the reactor 1, and the discharge end of the screw conveyor extends above the spreading wheel 2 in the reactor 1.

[0030] The zinc powder feeder provided by the utility model avoids concentrated feeding of zinc powder at a single position, improves the dispersion uniformity of zinc powder feeding, and simultaneously breaks up lumps in the zinc powder, thereby improving the zinc powder agglomeration breaking effect and avoiding material blockage.

[0031] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0033] Example 1

[0034] Please refer to Figure 1-4 A zinc powder feeder includes a reactor 1, a spreading wheel 2 rotatably mounted on the top of the reactor 1, a first motor 3 providing power for the rotation of the spreading wheel 2, and a screw conveyor. The screw conveyor is fixedly mounted on the top of the reactor 1, and the discharge end of the screw conveyor extends above the spreading wheel 2 in the reactor 1.

[0035] Please refer to Figure 3-5 The top of the spreading wheel 2 is provided with a groove 4 which is concave toward the middle, and a plurality of circumferentially evenly distributed spreading plates 5 are installed on the inner wall of the groove 4; further, the discharge end of the screw conveyor is located at the eccentric part of the middle of the groove 4; the spreading plates 5 are arranged radially along the central axis 15 on the spreading wheel 2, and the middle part of the groove 4 bulges upward.

[0036] In the zinc powder feeder provided in this embodiment, the zinc powder discharged from the discharge port of the screw conveyor falls to the eccentric center of the groove 4 and collides with the rotating spreading plate 5. The impact of the spreading plate 5 can further improve the effect of breaking up the agglomerates in the zinc powder. At the same time, under the action of the groove 4, the zinc powder thrown out by the centrifugal force moves obliquely upward, and the thrown zinc powder contacts the top of the reactor 1 and then falls. The falling zinc powder does not only fall along the inner wall of the reactor 1, but falls in a dispersed annular surface. In this way, the dispersion of the zinc powder entering the reactor 1 can be further improved.

[0037] Example 2

[0038] The zinc powder feeder provided in Example 1 is further optimized, specifically, as Figure 4As shown, the screw conveyor includes a conveying cylinder 6, a rotating shaft 7 rotatably installed in the conveying cylinder 6, an upper hopper 8 installed in the middle of the conveying cylinder 6 and connected to the interior of the conveying cylinder 6, and a second motor 9 installed at one end of the conveying cylinder 6 and providing power for the rotation of the rotating shaft 7; two spiral conveying blades 10 arranged symmetrically with respect to the vertical plane of the rotating shaft 7 are provided on the rotating shaft 7, and a material box 11 connected to the interior of the conveying cylinder 6 is installed at both ends of the conveying cylinder 6, and a material pipe 12 extending eccentrically above the middle of the spreading wheel 2 in the reactor 1 is installed at the bottom of the material box 11; further, the two material pipes 12 are symmetrically arranged on both sides of the vertical center axis of the spreading wheel 2.

[0039] A mounting frame 13 is installed in the material box 11 , and a permanent magnet plate 14 is installed on the mounting frame 13 .

[0040] A shaft 15 is rotatably mounted on the material box 11, and the mounting frame 13 is fixedly mounted on the shaft 15. An arc-shaped seat 16 is fixedly mounted on the outer wall of the material box 11. A limiting bolt 17 is screwed onto the end of the shaft 15, and the shaft 15 is locked with the arc-shaped seat 16 through the limiting bolt 17. Furthermore, a through opening is provided on the mounting frame 13 to allow the rotating shaft 7 to pass through. The diameter of the through opening is larger than the outer diameter of the rotating shaft 7 to prevent the rotating shaft 7 from interfering with the rotation of the mounting frame 13.

[0041] The zinc powder feeder provided in this embodiment is configured such that zinc powder is loaded at the loading hopper 8, the second motor 9 is started, and the second motor 9 drives the rotating shaft 7 to rotate. Under the action of the two spiral conveying blades 10, the zinc powder is dispersed and fed to both sides along the conveying cylinder 6, and the zinc powder entering the reactor 1 is divided into two streams and falls onto the throwing wheel 2, so as to improve the uniformity of the zinc powder throwing by the throwing wheel 2, thereby improving the uniformity of the zinc powder dispersion entering the reactor 1; the zinc powder conveyed by the conveying cylinder 6 enters the material box 11 and is connected to the permanent magnet plate 14. The permanent magnet plate 14 can absorb the residual iron filings and other metals in the zinc powder, remove impurities from the zinc powder, and ensure the purity of the zinc powder; according to the conveying speed of the screw conveyor for the zinc powder, the inclination angle of the mounting frame 13 and the permanent magnet plate 14 on the mounting frame 13 can be changed by rotating the shaft 15 to ensure the contact area between the permanent magnet plate 14 and the zinc powder falling into the material box 11. After the inclination angle of the permanent magnet plate 14 is adjusted, the shaft 15 is locked with the arc seat 16 by tightening the bolts to prevent the permanent magnet plate 14 from rotating.

[0042] Specifically, an inspection port is provided on the top of the material box 11, and a cover 18 is detachably installed at the inspection port; through the inspection port, the material box 11 can be cleaned, inspected and maintained, thereby improving operational convenience.

[0043] Specifically, a rotor 19 is rotatably installed in the upper hopper 8, and blades 20 are evenly distributed circumferentially on the rotor 19. A third motor 21 is fixedly installed on the upper hopper 8 to provide power for the rotation of the rotor 19; the third motor 21 is preferably a speed-regulating motor; when the zinc powder enters the upper hopper 8, the third motor 21 is started to drive the rotor 19 and the blades 20 on the rotor 19 to rotate, and the third motor 21 regulates the speed of the blades 20, thereby controlling the amount of zinc powder entering the conveying cylinder 6, thereby preventing excessive zinc powder from entering the middle part of the conveying cylinder 6 and causing the spiral conveying blades 10 to be stuck.

[0044] Specifically, a discharge port is provided on the side wall of the upper hopper 8, and a sealing plate 22 is detachably installed at the discharge port; when the device is shut down, excess zinc powder in the upper hopper 8 can be discharged through the discharge port to reduce the residual zinc powder in the upper material.

[0045] The use process of the zinc powder feeder provided by the present invention is as follows: zinc powder is put into the upper hopper 8, the third motor 21 is started, the third motor 21 drives the rotor 19 and the blade 20 to rotate, and the zinc powder is dispersed and sent into the conveying cylinder 6, the second motor 9 is started, and the second motor 9 drives the rotating shaft 7 and the two spiral conveying blades 10 to rotate. Under the action of the spiral conveying blades 10, the zinc powder moves to both sides along the conveying cylinder 6. During the process of the zinc powder falling into the material box 11, the iron filings in the zinc powder are adsorbed and removed by the plate 14. Then the zinc powder enters the reactor 1 and falls into the middle of the groove 4. The first motor 3 is started, and the first motor 3 drives the throwing wheel 2 to rotate. The zinc powder moves obliquely upward under the action of centrifugal force. The zinc powder collides with the top wall and the inner side wall of the reactor 1 to form a "ring surface". The dispersed zinc powder falls into the reactor 1 under the action of gravity, thereby realizing the dispersed feeding of the zinc powder into the reactor 1.
