Description

Technical Field

[0001] This utility model relates to the field of diamond micron powder processing technology, and in particular to an automatic screening device for diamond micron powder airflow crushing. Background Technology

[0002] Diamond micron powder is a new type of ultra-hard and ultra-fine abrasive formed by processing synthetic diamond single crystals through special processes. It is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, and optical glass.

[0003] Diamond micron powder is an important superhard material widely used in precision machining, electronic devices and other fields. In the production process of diamond micron powder, screening is a key step to ensure the uniformity of product particle size. In the current technology, most screening devices are prone to agglomeration of micron powder before screening. Direct screening will lead to inaccurate particle size detection, mixed qualified and unqualified products, and material is prone to accumulation and blockage during the feeding process, resulting in uneven feeding, affecting screening efficiency and lack of practicality. Therefore, it is necessary to redesign the automatic screening device for diamond micron powder airflow crushing to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic screening device for diamond micron powder airflow crushing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic screening device for airflow crushing of diamond micron powder includes a base plate with multiple pulleys fixedly installed on its bottom wall. A screening box is fixedly installed on the upper surface of the base plate. A feeding channel is fixedly installed on the outer wall of the screening box via a fixed frame. A feeding pipe and a discharge pipe communicating with the interior are fixedly installed on the outer wall of the feeding channel. An auger blade is rotatably installed inside the feeding channel. A first motor connected to the rotating shaft of the auger blade is fixedly installed on the upper surface of the feeding channel. A dispersing channel communicating with the interior is fixedly installed on the upper surface of the screening box. The end of the discharge pipe communicates with the interior of the dispersing channel. A dispersing shaft is rotatably installed inside the dispersing channel. A second motor connected to a dispersing shaft is fixedly installed on the upper end face of the dispersing channel. Multiple dispersing rods are fixedly installed on the outer wall of the dispersing shaft through an mounting sleeve. Guide sleeves are fixedly connected to both inner walls of the screening box through connecting rods. Guide rods are slidably installed inside the guide sleeves. A filter screen plate is fixedly installed at one end of the guide rod, and an extrusion frame is fixedly installed at the other end of the guide rod. An extrusion shaft is rotatably installed inside the screening box. A third motor connected to the extrusion shaft is fixedly installed on the outer wall of the screening box. An eccentric cam that mates with the inner wall of the extrusion frame is fixedly installed on the outer wall of the extrusion shaft. A collection box is slidably installed on the outer wall of the screening box through a sliding opening.

[0007] Preferably, both the feeding pipe and the discharging pipe are inclined, the discharging pipe is located above the feeding pipe, and a feeding hopper is fixedly installed at the end of the feeding pipe.

[0008] Preferably, the filter screen is inclined, and the outer wall of the screening box has an outlet that matches the lower side of the filter screen. A guide frame that matches the outlet is fixedly installed on the outer wall of the screening box.

[0009] Preferably, an electric push rod is fixedly installed on the upper end face of the screening box via a support plate, and the telescopic end of the electric push rod is fixedly connected to a baffle that cooperates with the discharge port via a moving block, and a sealing gasket is fixedly installed inside the baffle.

This ensures the accuracy of screening and improves product quality.

[0013] 2. By setting up components such as a feeding channel, auger blades, and a first motor, uniform material feeding is achieved. The rotation of the auger blades can stably convey the material upward, avoiding the problem of material accumulation and blockage in traditional feeding methods, ensuring the continuity and stability of the screening process, and improving screening efficiency.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-5 An automatic screening device for airflow crushing of diamond micron powder includes a base plate 1. Multiple pulleys 2 are fixedly installed on the bottom wall of the base plate 1. A screening box 3 is fixedly installed on the upper surface of the base plate 1. A feeding channel 5 is fixedly installed on the outer wall of the screening box 3 via a fixed frame 4. A feeding pipe 6 and a discharge pipe 7, communicating with the interior, are fixedly installed on the outer wall of the feeding channel 5. An auger blade 9 is rotatably installed inside the feeding channel 5. A first motor 10, connected to the rotating shaft of the auger blade 9, is fixedly installed on the upper surface of the feeding channel 5. A dispersing channel 11, communicating with the interior, is fixedly installed on the upper surface of the screening box 3. The end of the discharge pipe 7 communicates with the interior of the dispersing channel 11. A dispersing shaft 12 is rotatably installed inside the dispersing channel 11. A fixed dispersing shaft 12 is fixed on the upper surface of the dispersing channel 11. A second motor 13 connected to the dispersing shaft 12 is installed. Multiple dispersing rods 15 are fixedly installed on the outer wall of the dispersing shaft 12 via mounting sleeves 14. Guide sleeves 17 are fixedly connected to both inner walls of the screening box 3 via connecting rods 16. Guide rods 18 are slidably installed inside the guide sleeves 17. A filter screen plate 19 is fixedly installed at one end of the guide rod 18, and an extrusion frame 20 is fixedly installed at the other end of the guide rod 18. An extrusion shaft 21 is rotatably installed inside the screening box 3. A third motor 23 connected to the extrusion shaft 21 is fixedly installed on the outer wall of the screening box 3. An eccentric cam 22 that mates with the inner wall of the extrusion frame 20 is fixedly installed on the outer wall of the extrusion shaft 21. A collection box 24 is slidably installed on the outer wall of the screening box 3 via a sliding opening.

[0022] Furthermore, the fixed frame 4 here is made of high-strength alloy material, which can effectively ensure the stability of the connection between the feeding channel 5 and the screening box 3, and avoid the connection from loosening due to vibration during the operation of the device. The surface of the auger blade 9 is treated with wear-resistant coating, which extends its service life in the process of conveying diamond powder.

[0023] Both the feeding pipe 6 and the discharge pipe 7 are inclined. The discharge pipe 7 is located above the feeding pipe 6, and the feeding hopper 8 is fixedly installed at the end of the feeding pipe 6.

[0024] Furthermore, the angle between the feeding pipe 6 and the horizontal plane is set to 30°. This angle can ensure that the diamond powder slides smoothly into the feeding channel 5 and avoid material accumulation. The inner wall of the feeding hopper 8 is made of smooth stainless steel, and the edge of the hopper opening is rounded to facilitate the operator to add materials and reduce material residue.

[0025] The filter screen 19 is inclined, and the outer wall of the screening box 3 has an outlet that matches the lower side of the filter screen 19. A guide frame 25 that matches the outlet is fixedly installed on the outer wall of the screening box 3.

[0026] Furthermore, the angle between the filter plate 19 and the horizontal plane is 15°, which facilitates the sliding of diamond micro powder that does not meet the particle size requirements after sieving towards the discharge port along the filter plate 19.

[0027] An electric push rod 27 is fixedly installed on the upper surface of the screening box 3 via a support plate 26. The telescopic end of the electric push rod 27 is fixedly connected to a baffle 29 that cooperates with the discharge port via a moving block 28. A sealing gasket is fixedly installed inside the baffle 29.

[0028] Furthermore, the support plate 26 is connected to the screening box 3 by welding to ensure that the electric push rod 27 is firmly installed.

[0029] A controller 30 is fixedly installed on the outer wall of the screening box 3. The controller 30 is electrically connected to the first motor 10, the second motor 13, the third motor 23, and the electric push rod 27.

[0030] Furthermore, the housing of the controller 30 is designed to be waterproof and dustproof, adapting to the complex working environment that the device may be in. The controller 30 is equipped with a touch screen and multiple control buttons. Operators can set the speed of each motor and the extension and retraction frequency of the electric push rod 27 through the touch screen, or they can operate it manually through the control buttons, which improves the ease of operation of the device.

[0031] When using this utility model, the power is turned on, and the speed of the first motor 10, the second motor 13, and the third motor 23 and the action interval of the electric push rod 27 are set by the controller 30. The diamond powder to be screened is poured into the feeding hopper 8. The first motor 10 drives the auger blades 9 to rotate, conveying the material upward and sending it into the dispersing channel 11 through the discharge pipe 7. At the same time, the second motor 13 starts synchronously, driving the dispersing shaft 12 to rotate at high speed. The multiple dispersing rods 15 installed on the dispersing shaft 12 then make circular motions. When the material enters the dispersing channel 11 from the discharge pipe 7, the high-speed rotating dispersing rods 15 will form a strong impact and stirring effect on the material, which will fully disperse any diamond powder that may be agglomerated, avoiding the problem of misjudgment of particle size in subsequent screening due to particle agglomeration. The dispersed material falls from the bottom opening of the dispersing channel 11 onto the filter plate 19 below under the action of gravity.

[0032] At this time, the third motor 23 drives the extrusion shaft 21 to rotate. The eccentric cam 22 fixed on the extrusion shaft 21 rotates together with the shaft. Since the center of gravity of the eccentric cam 22 is off from the center of rotation, it will continuously generate periodic thrust on the extrusion frame 20 during rotation. After the extrusion frame 20 is subjected to force, it drives the guide rod 18 to reciprocate linearly along the guide sleeve 17, which in turn causes the filter plate 19 connected to the guide rod 18 to generate high-frequency vibration. This vibration can accelerate the flow of diamond powder on the filter plate 19 on the one hand, and promote the fine powder that meets the particle size requirements to quickly pass through the screen holes and fall into the collection box 24 below. The coarse powder that exceeds the particle size standard will move towards the lower side of the filter plate 19 under the dual action of vibration and the tilt angle of the filter plate 19, and gradually approach the discharge port of the screening box 3.

[0033] When the device reaches the preset discharge interval time of the controller 30, the controller 30 sends an action signal to the electric push rod 27. The telescopic end of the electric push rod 27 retracts, and the baffle 29 is lifted upward through the moving block 28. The discharge port opens accordingly, and the coarse powder accumulated near the discharge port slides out along the inclined surface of the filter screen plate 19 and is guided to the external recycling container through the guide frame 25, realizing the automatic discharge of unqualified materials. After the discharge is completed, the telescopic end of the electric push rod 27 extends, the baffle 29 falls back down and fits tightly with the discharge port, and the sealing gasket ensures that the material will not leak from the gaps during the screening process.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
