Description

Technical Field

[0001] The utility model relates to the technical field of particle classifiers, in particular to a calcium carbonate particle classifier. Background Art

[0002] A calcium carbonate particle classifier is a professional device mainly used for precisely classifying calcium carbonate particles. It classifies calcium carbonate particles into different grades according to the characteristics such as the size and shape of the particles to meet the needs of different industries and applications. The working principle of the classifier is usually based on principles such as screening, gravity or centrifugal force. After the material enters the classifier, through internal devices such as a sieve mesh or a classification wheel, the classification and separation of the particles are realized. Larger particles will be intercepted or excluded, while smaller particles will pass through the sieve mesh or the classification wheel and continue to enter the next classification stage.

[0003] Most of the existing classifiers use sieve meshes to screen and classify in order from large to small. However, during the screening process, larger materials are likely to block the uppermost sieve mesh, resulting in a reduction in the screening efficiency of the classifier. Therefore, the utility model proposes a calcium carbonate particle classifier. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art and propose a calcium carbonate particle classifier.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A calcium carbonate particle classifier includes a particle classifier body. The particle classifier body includes a classification box. A screening component is arranged in the classification box, and a dredging component is correspondingly arranged directly below the screening component.

[0006] The dredging component includes a rotating seat movably connected to the inner wall of the classification box. Dredging plates are rotatably connected to both ends of the rotating seat. Dredging rods are arranged on the dredging plates. The mutually remote ends of the dredging plates are movably connected to the inner wall of the classification box. A connecting frame is arranged at the bottom of the rotating seat. A connecting plate is arranged below the connecting frame. A second spring is arranged between the connecting plate and the connecting frame.

[0007] As a preferred embodiment, the screening component includes a screening plate. First springs are arranged between the four corners of the screening plate and the classification box. Screening holes are formed in the screening plate. The screening holes are distributed in a rectangular shape, and the distance between adjacent two screening holes is equal. Limit sliders are arranged at both ends of the screening plate. The screening plate is slidably connected to the inner wall of the classification box through the limit sliders.

[0008] The beneficial effects of adopting the above further scheme are as follows: Firstly, the screening plate is limited by the limit slider. Under the action of the limit slider, the screening plate can not only slide up and down on the inner wall of the grading box, but also be prevented from separating from or tilting with the grading box during displacement under the action of the limit slider. Further, through the first spring, the screening plate can drive the screening plate to lift and reset under the action of the first spring after receiving a downward pressure, so that the screening plate shakes to accelerate the grading efficiency of the screening holes.

[0009] As a preferred embodiment, the dredging rods are distributed in a rectangular shape, the distribution positions of the dredging rods are the same as those of the screening holes, and the diameter of the dredging rods is smaller than that of the screening holes.

[0010] The beneficial effects of adopting the above further scheme are as follows: When the drive shaft plate drives the screening plate to press down, the screening plate squeezes the rotating seat, so that the rotating seat and the two dredging plates are on the same horizontal line. At this time, the dredging rod penetrates through the screening hole to eject the material stuck in the screening hole and clean the hole wall of the screening hole to ensure the normal operation of the grader.

[0011] As a preferred embodiment, drive shaft plates are rotatably connected above the two screening plates on the grading box, a drive motor is arranged on the outer wall of the grading box at the position of the drive shaft plate, and the drive motor is connected to the drive shaft plate.

[0012] The beneficial effects of adopting the above further scheme are as follows: The drive shaft plate drives the screening plate to displace downward. Due to the structural design of the drive shaft plate, when the longer end of the drive shaft plate rotates to the vertical state, it can drive the screening plate to displace downward. When the shorter end of the drive shaft plate rotates to the horizontal state, the screening plate loses extrusion and drives the screening plate to lift and reset under the action of the first spring.

[0013] As a preferred embodiment, a feeding port is opened at the top of the grading box, discharge ports are opened on both sides of the two screening plates on the grading box, and a guide plate is embedded above the discharge ports on the grading box.

[0014] The beneficial effects of adopting the above further scheme are as follows: The material is fed into the grading box through the feeding port, and the graded material is discharged out of the grading box through the discharge port. Further, the guide plate limits the material sliding down on the dredging plate to prevent the material from being directly discharged out of the grading box through the dredging plate.

[0015] As a preferred embodiment, two screening components and two dredging components are respectively arranged, and the diameter of the screening holes on the lower screening plate is smaller than that of the screening holes on the upper screening plate.

[0016] The beneficial effect of adopting the above further scheme is: because the diameter of the screening hole on the lower screening plate is smaller than the diameter of the first spring on the upper screening plate, when the device classifies the material, the larger material is first blocked by the upper screening hole, and the material smaller than the diameter of the upper screening hole can smoothly fall into the lower screening plate for further classification.

[0017] Compared with the prior art, the advantages and positive effects of the utility model are:

[0018] 1. In the utility model, when the screening plate is pressed down, it first contacts with the rotating seat, and under the action of the extrusion force, the rotating seat is driven to move downward, causing the second spring to deform and shrink. At this time, the dredging plates on both sides of the rotating seat slide to both sides, so that the dredging plates and the rotating seat are on the same horizontal line. At this time, under the action of the dredging rod, the materials stuck in the screening hole are pushed out to avoid the screening hole being stuck and causing the classifier to stop working. When the downward pressure of the screening plate disappears, the rotating seat slides upward and resets under the action of the second spring. At this time, the dredging plate is in an inclined state to facilitate the unloading of materials after classification. Compared with the traditional classifier, the device improves the stability during use.

[0019] 2. In the utility model, the screening plate is driven to move up and down and vibrate reciprocatingly by the driving shaft plate. When the longer end of the driving shaft plate rotates to a vertical state, the screening plate can be driven to move downward. When the shorter end of the driving shaft plate rotates to a horizontal state, the screening plate loses its extrusion. Under the action of the first spring, the screening plate is driven to lift and reset. By repeatedly shaking the screening plate, the material can be accelerated to pass through the screening hole during grading, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1-4 shown, the present invention provides a technical solution: a calcium carbonate particle classifier, including a particle classifier body 1. The particle classifier body 1 includes a classification box 2. A screening component 3 is arranged in the classification box 2, and a dredging component 4 is correspondingly arranged directly below the screening component 3; the dredging component 4 includes a rotating seat 43, and the rotating seat 43 is movably connected to the inner wall of the classification box 2. Dredging plates 44 are rotatably connected to both ends of the rotating seat 43. Dredging rods 45 are arranged on the dredging plates 44. The mutually remote ends of the dredging plates 44 are movably connected to the inner wall of the classification box 2. A connecting frame 431 is arranged at the bottom of the rotating seat 43. A connecting plate 41 is arranged below the connecting frame 431. A second spring 42 is arranged between the connecting plate 41 and the connecting frame 431. The dredging rods 45 are distributed in a rectangular shape, and the distribution positions of the dredging rods 45 are the same as the distribution positions of the screening holes 32. The diameter of the dredging rods 45 is smaller than the diameter of the screening holes 32. Two screening components 3 and two dredging components 4 are respectively arranged. The diameter of the screening holes 32 on the lower screening plate 31 is smaller than the diameter of the screening holes 32 on the upper screening plate 31. Under the action of the extrusion force, the rotating seat 43 is driven to displace downward, causing the second spring 42 to deform and contract. At this time, the dredging plates 44 on both sides of the rotating seat 43 slide to both sides, making the dredging plates 44 and the rotating seat 43 on the same horizontal line. At this time, the materials stuck and blocked in the screening holes 32 are pushed out by the dredging rods 45, solving the technical problem of blockage of the screening holes 32 during use.

[0031] Even further, as Figure 3As shown in the figure: The screening component 3 includes a screening plate 31. First springs 34 are arranged between the four corners of the screening plate 31 and the grading box 2. Screening holes 32 are formed in the screening plate 31. The screening holes 32 are distributed in a rectangular shape, and the spacing between two adjacent screening holes 32 is equal. Limiting sliders 33 are arranged at both ends of the screening plate 31. The screening plate 31 is slidably connected to the inner wall of the grading box 2 through the limiting sliders 33. Driving shaft plates 25 are rotatably connected above the two screening plates 31 on the grading box 2. A driving motor 24 is arranged on the outer wall of the grading box 2 at the position of the driving shaft plate 25. The driving motor 24 is connected to the driving shaft plate 25, and the screening plate 31 is driven to move up and down to vibrate reciprocally through the driving shaft plate 25. When the longer end of the driving shaft plate 25 rotates to the vertical state, the screening plate 31 can be driven to move downward. When the shorter end of the driving shaft plate 25 rotates to the horizontal state, the screening plate 31 loses extrusion, and under the action of the first spring 34, the screening plate 31 is driven to lift and reset. By repeatedly shaking the screening plate 31, the material can pass through the screening holes 32 more quickly during grading.

[0032] In the above solution, there is also a problem that after the material passes through the screening holes 32, under the action of the dredging plate 44, it directly discharges from the discharge port 23 out of the grading box 2, as Figure 1 shown in the figure: In this solution, discharge ports 23 are formed on both sides of the two screening plates 31 on the grading box 2. Guide plates 21 are embedded above the discharge ports 23 on the grading box 2. The material is fed into the interior of the grading box 2 through the feeding port 22, and the graded material is discharged out of the grading box 2 through the discharge ports 23. Further, the guide plates 21 limit the material sliding on the dredging plate 44 to prevent the material from directly discharging out of the grading box 2 through the dredging plate 44.

[0033] Working principle:

[0034] As Figures 1-4As shown in the figure, first, place the particle classifier body 1 at the designated position. Secondly, put the material into the guide plate 21 through the feeding port 22. Then, turn on the driving motor 24 to drive the driving shaft plate 25 to rotate. Under the action of the driving shaft plate 25, when the longer end of the driving shaft plate 25 rotates to the vertical state, it drives the screening plate 31 to move downward. When the shorter end of the driving shaft plate 25 rotates to the horizontal state, the screening plate 31 loses extrusion. Under the action of the first spring 34, it drives the screening plate 31 to lift and reset. At this time, by shaking the screening plate 31, the material on the screening plate 31 shakes up and down. During the shaking process, the material smaller than the aperture of the screening hole 32 passes through the screening plate 31 and falls on the lower screening plate 31 for material classification. During use, the material that cannot pass through the screening hole 32 is discharged outside the classification box 2 through the discharge port 23. When screening, the screening plate 31 presses down and contacts the rotating seat 43. Under the action of the extrusion force, it drives the rotating seat 43 to move downward, causing the second spring 42 to deform and contract. At this time, the dredging plates 44 on both sides of the rotating seat 43 slide to both sides, so that the dredging plates 44 and the rotating seat 43 are on the same horizontal line. At this time, under the action of the dredging rod 45, the material stuck and blocked in the screening hole 32 is pushed out to prevent the screening hole 32 from being stuck and causing the classifier to stop working.

[0035] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
