Description

Technical Field

[0001] This utility model relates to the field of calcium powder processing technology, and in particular to a calcium powder screening device for high-purity flux. Background Technology

[0002] Calcium powder is a powder material with calcium as its main component. Its main component is calcium carbonate, and some calcium powder also contains calcium oxide or calcium hydroxide. These calcium compounds are widely available. For example, calcium carbonate powder can be obtained from limestone, calcite and other ores.

[0003] In the production process of calcium carbonate powder, there is a step that requires screening the produced calcium carbonate powder. However, most of the existing screening devices can only perform screening once, resulting in incomplete screening and a low qualified rate of the screened calcium carbonate powder. Then, the unqualified calcium carbonate powder has to be screened again, which is inefficient and affects the overall production efficiency of the enterprise. Utility Model Content

[0004] The purpose of this invention is to address the problem that most existing screening devices can only perform one screening operation, resulting in incomplete screening and a low qualified rate of calcium carbonate powder after screening. Consequently, unqualified calcium carbonate powder must be screened again, which is inefficient and affects the overall production efficiency of the enterprise. Therefore, this invention proposes a high-purity flux calcium powder screening device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-purity flux calcium powder screening device, comprising a feeding assembly and a screening assembly disposed at the lower end of the feeding assembly. The feeding assembly includes a feeding pipe, and a filter plate is inclinedly disposed inside the feeding pipe. The screening assembly includes a housing, and the feeding pipe is fixedly installed on the upper surface of the housing and is connected to the housing. An isolation plate is disposed inside the housing, dividing the housing into two independent spaces. Two sets of feeding hoppers are fixedly connected to the bottom surface of the housing, and the two sets of feeding hoppers correspond to the two sets of independent spaces inside the housing. A fan is disposed at the upper end of the housing, and the output end of the fan extends through the housing into its interior. An installation frame is installed inside the housing, and the installation frame is disposed in one of the independent spaces. A screening frame is disposed at the upper end of the installation frame, and a spring is elastically connected between the installation frame and the screening frame.

[0006] Preferably, a discharge port is provided on one side of the feed pipe, and a guide frame is fixedly connected to one side of the feed pipe. The lower end of the filter plate matches the discharge port, and the discharge port matches the guide frame.

[0007] This is used to conveniently perform preliminary filtration of calcium powder that is about to be added to the chamber, filtering out only the large particles of calcium powder.

[0008] Preferably, a mounting plate is fixedly connected to one side of the housing, the fan is mounted on the upper surface of the mounting plate, and a support rod is fixedly connected to the lower bottom surface of the mounting plate, with one end of the support rod mounted on the outer surface of the housing.

[0009] Used to support the wind turbine, enabling it to operate normally.

[0010] Preferably, a baffle plate is fixedly connected to the inner wall of the box, and the fan output end is located below the baffle plate;

[0011] This is to prevent particles of calcium powder that fall into the housing from impacting the blower's output end, thereby affecting the blower's normal operation.

[0012] Preferably, a support bar is fixedly connected to both the inner wall of the box and one side of the isolation plate, and a mounting bracket is slidably connected to the upper surface of the support bar;

[0017] This is used to drive the impact rod at the output end of the fan, so that the impact rod hits the inclined block, thereby causing the filter frame to vibrate and facilitate material feeding.

[0018] Preferably, a guide post is fixedly connected to the upper surface of the mounting frame, the upper end of the guide post passes through the screening frame, and a nut is threadedly connected to the upper end of the guide post, with the bottom surface of the screening frame fitting against the nut;

[0019] Used to guide the filter frame, ensuring it can only move in a straight line, up and down.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] This utility model proposes a high-purity calcium powder screening device for flux. After the calcium powder enters the box, it is first purged by a blower, and then the smaller particles are separated. Then, the calcium powder is screened again through a screening frame. Particles smaller than the filter holes are discharged from the hopper, while larger particles remain in the screening frame, thus obtaining three portions of calcium powder with different particle sizes.

[0031] Reference Figure 1-5 The present invention provides an embodiment of a high-purity flux calcium powder screening device, comprising a feeding component 1 and a screening component 2 disposed at the lower end of the feeding component 1. The feeding component 1 includes a feeding pipe 11, the top of which is configured as an inverted bucket shape, so that the operator can more conveniently add the calcium powder to be screened into the feeding pipe 11 and then let it enter the housing 21 for screening. A filter plate 12 is inclinedly disposed inside the feeding pipe 11 to perform preliminary screening of the calcium powder added to the feeding pipe 11 and screen out large particles in the calcium powder.

[0032] The screening component 2 includes a housing 21, with a feed pipe 11 fixedly installed on the upper surface of the housing 21 and connected to the housing 21. An isolation plate 22 is installed inside the housing 21, dividing the interior into two independent spaces. Two sets of hoppers 24 are fixedly connected to the bottom surface of the housing 21, corresponding to the two independent spaces inside the housing 21, thus facilitating the separation of calcium powder with different particle sizes. A fan 26 is installed at the top of the housing 21, generating blowing force to screen the calcium powder entering the housing 21 from the feed pipe 11, separating out the smallest calcium powder particles. The powder is then discharged from one of the hoppers 24 into the housing 21. The output end of the blower 26 extends through the housing 21 into its interior. An installation frame 27 is installed inside the housing 21. The installation frame 27 is set in one of the independent spaces. A screening frame 28 is set on the upper end of the installation frame 27 to screen the calcium powder entering the housing 21. The larger calcium powder particles are screened out and stored, while the smaller particles are discharged from another hopper 24. A spring 29 is elastically connected between the installation frame 27 and the screening frame 28, which gives the screening frame 28 a certain range of motion and allows it to reset, thereby generating vibration to facilitate the discharge of calcium powder.

[0033] A discharge port 13 is provided on one side of the feed pipe 11, and a guide frame 14 is fixedly connected to one side of the feed pipe 11. The lower end of the filter plate 12 matches the discharge port 13, and the discharge port 13 matches the guide frame 14, so that the large calcium powder particles screened by the filter plate 12 can be conveniently discharged from the feed pipe 11. A mounting plate 211 is fixedly connected to one side of the box body 21, and the blower 26 is set on the upper surface of the mounting plate 211. A support rod 212 is fixedly connected to the bottom surface of the mounting plate 211. One end of the support rod 212 is installed on the outer surface of the box body 21 to support the blower 26 so that it can work normally.

[0034] A baffle plate 213 is fixedly connected to the inner wall of the box 21. The output end of the fan 26 is located below the baffle plate 213 to prevent the calcium powder in the feed pipe 11 from entering the box 21 and impacting the fan blades of the fan 26, thus affecting its normal operation. Support bars 23 are fixedly connected to both the inner wall of the box 21 and one side of the isolation plate 22. A mounting bracket 27 is slidably connected to the upper surface of the support bar 23.

[0035] A support leg 25 is fixedly connected to the bottom surface of the housing 21, and a support plate 251 is fixedly connected to the bottom surface of the support leg 25 to support the entire device so that it can work normally. An impact rod 261 is fixedly connected to the output end of the fan 26. An inclined block 281 is fixedly connected to the upper surface of the screening frame 28. The impact rod 261 matches the inclined block 281. The fan 26 drives the impact rod 261 to rotate, and then the impact rod 261 impacts the inclined block 281, thereby applying a downward pressure to the screening frame 28. The spring 29 then resets it, causing the screening frame 28 to vibrate for easy material feeding. A guide post 271 is fixedly connected to the upper surface of the mounting frame 27. The upper end of the guide post 271 passes through the screening frame 28, and a nut 272 is threadedly connected to the upper end of the guide post 271. The bottom surface of the screening frame 28 fits against the nut 272 to guide the screening frame 28 so that it can only move in a straight line up and down.

[0036] Working principle: First, a container is placed on the box 21 to facilitate the discharge of large calcium powder particles from the feed pipe 11. After everything is ready, the blower 26 is turned on, and then the calcium powder to be screened is put into the feed pipe 11. Then, the large calcium powder particles are screened through the filter plate 12. The screened calcium powder falls into the box 21. Then, under the operation of the blower 26, the smallest calcium powder particles are blown away and discharged into the box 21 through one of the hoppers 24. The larger particles fall into the screening frame 28. During the operation of the blower 26, the impact rod 261 is rotated, so that the impact rod 261 contacts the inclined block 281, thereby applying a downward force to the screening frame 28. Then, under the action of the spring 29, the screening frame 28 vibrates, which facilitates the screening of small calcium powder particles. Then, it is discharged into the box 21 through another hopper 24, finally obtaining four kinds of calcium powder with different particle sizes.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
