Description

Technical Field

[0001] This utility model relates to the field of zinc oxide powder technology, specifically to a zinc oxide powder magnetic separation and impurity removal device. Background Technology

[0002] Magnetic separation of zinc oxide powder utilizes the magnetic difference between magnetic particles such as iron impurities and zinc oxide. A high-strength magnetic field attracts the iron impurities, while the zinc oxide remains unaffected, achieving efficient separation. Magnetic separation can continuously process large quantities of material, and the equipment is easy to operate (such as automated zinc oxide powder iron removal equipment). It can stably remove micron-sized iron impurities, ensuring the purity of zinc oxide.

[0003] For example, Chinese Patent No. CN219985002U discloses a powder magnetic separation device. This utility model uses the rotation of an electromagnet and the magnetic baffle in the conveyor belt to fully absorb the iron minerals in the bauxite powder during the descent process, which is more conducive to the purification of bauxite and the magnetic separation effect is better. At the same time, by using the electromagnetic effect and the conveyor belt, it is easier to collect the iron ore after magnetic separation, clean the iron ore adsorbed on the magnetic shaft and the conveyor belt, and improve the efficiency of multiple magnetic separations.

[0004] However, existing powder magnetic separation equipment relies solely on electromagnets and electromagnetic plates for magnetic separation and impurity removal. In practical use, this single method is inefficient and struggles to quickly and thoroughly separate impurities. Furthermore, powder easily adheres to the electromagnets and electromagnetic plates along with iron filings, making subsequent cleaning difficult. This not only results in a significant waste of powder resources but also increases production costs and operational complexity. Therefore, there is room for further improvement.

[0005] Therefore, we propose a magnetic separation device for removing impurities from zinc oxide powder to solve the problems mentioned above. Utility Model Content

This device relies solely on electromagnets and electromagnetic plates for magnetic separation and impurity removal, which is inefficient in practice and fails to quickly and thoroughly separate impurities. Furthermore, powder easily adheres to the electromagnets and electromagnetic plates along with iron filings, making subsequent cleaning difficult. This not only results in significant waste of powder resources but also increases production costs and operational complexity, thus requiring further improvement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a magnetic separation and impurity removal device for zinc oxide powder, comprising:

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-5 This utility model provides a technical solution: a magnetic separation and impurity removal device for zinc oxide powder, comprising: a housing 1, a first motor 2, a first electromagnetic cylinder 3, a slag discharge port 4, a scraper 5, a collection box 6, an ear plate 7, a feeding port 8, a collection frame 9, a handle 10, a stop block 11, a spring 12, a limiting frame 13, a limiting rod 14, a push plate 15, a pull rod 16, a cleaning port 17, a cleaning door 18, a second electromagnetic cylinder 19, and a second motor 20.

[0035] Existing powder magnetic separation equipment relies solely on electromagnets and electromagnetic plates for powder separation and impurity removal. In practical use, this single-method approach is inefficient and fails to quickly and thoroughly separate impurities. Furthermore, powder easily adheres to the electromagnets and plates along with iron filings, making subsequent cleaning difficult. This not only results in significant waste of powder resources but also increases production costs and operational complexity, thus requiring further improvement.

[0036] When using a zinc oxide powder magnetic separation device for impurity removal, such as Figure 1 , Figure 3 and Figure 5 As shown, when performing magnetic separation and impurity removal of zinc oxide powder, the first step is to perform preparatory operations, check whether the connections of each component of the device are secure, and ensure that the collection frame 9 is correctly placed into the slot on the lower side of the box 1. At this time, the collection frame 9 is tightly fitted with the stop block 11, and the stop block 11 limits the collection frame 9 under the elastic force of the spring 12 to prevent it from sliding during operation; close the cleaning door 18 on the side of the collection box 6 to ensure that the inside of the collection box 6 is sealed.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the device is started to perform preliminary magnetic separation for impurity removal: the zinc oxide powder to be treated is slowly poured into the inside of the box 1 through the feeding port 8 on the upper side of the box 1, and the power supply of the first motor 2 and the first electromagnetic cylinder 3 is started at the same time. After the first motor 2 is powered on, its output shaft drives the first electromagnetic cylinder 3 to rotate slowly around the rotation connection point of the box 1. The first electromagnetic cylinder 3 generates a strong magnetic field. When the zinc oxide powder falls from the surface of the first electromagnetic cylinder 3, the iron impurities in the powder are adsorbed on the outer surface of the first electromagnetic cylinder 3 under the action of magnetic force. As the first electromagnetic cylinder 3 continues to rotate, the surface with adsorbed iron impurities moves to the position of contact with the scraper 5. The scraper 5 is in close contact with the first electromagnetic cylinder 3, scraping the iron impurities off the surface of the first electromagnetic cylinder 3. The scraped iron impurities slide down along the scraper 5 and are finally discharged from the outside of the device through the slag discharge port 4 on the side of the box 1, completing the preliminary magnetic separation for impurity removal; the zinc oxide powder after impurity removal continues to fall and finally falls into the collection frame 9 on the lower side of the box 1.

[0038] It should be noted that the first electromagnetic cylinders 3, which are symmetrically distributed, rotate in opposite directions, and the first electromagnetic cylinder 3 located on the left rotates counterclockwise, thereby ensuring that the iron filings are discharged to the outside of the device by the scraper 5.

[0039] like Figure 1 , Figure 2 and Figure 6 As shown, the power supply to the second motor 20 and the second electromagnetic cylinder 19 is activated simultaneously with the activation of the first motor 2. The second motor 20 is fixed on the ear plate 7 on the upper side of the collection box 6, and its output shaft drives the second electromagnetic cylinder 19 to rotate inside the collection box 6. The second electromagnetic cylinder 19 generates a magnetic field, which performs secondary adsorption on the magnetic impurities falling from the scraper 5, further improving the thoroughness of impurity removal.

[0040] When there is too much zinc oxide powder inside the collection box 6, which affects the removal of impurities, the pull rod 16 can be held and pushed to move along the sliding connection direction of the collection box 6. The pull rod 16 drives the push plate 15, which is fixedly connected to it, to move synchronously. The push plate 15 slides along the limiting rod 14 inside the collection box 6. The limiting rod 14 ensures that the moving direction of the push plate 15 is stable. The push plate 15 pushes the zinc oxide powder to the cleaning port 17 of the collection box 6 to realize powder recovery and reduce resource waste.

[0041] like Figure 1 and Figure 6 As shown, after processing is complete, cleaning and unloading operations are performed: Turn off all power, move the stop block 11 to disconnect it from the right side of the collection box 9, pull the handle 10 on the right side of the collection box 9 to remove the collection box 9 from the bottom of the box 1, pour out the residual powder inside, and then clean the collection box 9. Open the cleaning door 18 on the side of the collection box 6, and remove the recovered zinc oxide powder from the bottom of the collection box 6 through the cleaning port 17. At the same time, clean the residual impurities inside the collection box 6. After cleaning, close the cleaning door 18 and wait for the next operation.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
