Description

Technical Field

[0001] This utility model relates to the field of material drying technology, and in particular to a drying device for synthetic diamond raw materials. Background Technology

[0002] In the production of synthetic diamonds, the drying of raw materials (such as carbonaceous materials and catalyst powders) is a crucial preliminary step, as its drying effect directly affects the stability of subsequent synthesis processes and the quality of the final product. Raw materials are prone to absorbing moisture during storage or transportation due to environmental humidity and are susceptible to clumping. If these materials are directly introduced into the drying process, insufficient drying and excessive moisture residue can occur, thereby affecting the uniformity of crystal growth in synthetic diamonds.

[0003] Existing drying equipment generally suffers from the following problems: raw material agglomeration cannot be fully dispersed, making it difficult for hot air to penetrate the agglomerates during the drying process, resulting in a "dry outside, wet inside" phenomenon; raw materials tend to accumulate during transportation, resulting in limited contact area with hot air and low drying efficiency.

[0004] Therefore, those skilled in the art urgently need to develop a drying device for synthetic diamond raw materials. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying device for synthetic diamond raw materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drying device for synthetic diamond raw materials, including a dispersing box, a drying box at the bottom of the dispersing box, a material receiving component on the right side of the drying box, a hopper in the dispersing box, filter screens on the left and right side walls of the hopper, a first fan on the left side of the hopper, multiple dispersing plates inside the hopper, a drive motor at the rear end of the hopper, the output shaft of the drive motor located inside the hopper, and multiple dispersing plates evenly connected in a ring on the output shaft of the drive motor; The drying chamber has an internal frame, and the bottom of the hopper has a conveyor. The conveyor is placed at an angle with its left end higher than its right end. The conveyor is connected to the frame by an elastic component. The conveyor is equipped with a vibrating motor, and the bottom of the frame has a second fan. The receiving assembly includes a material pipe, the top of which is connected to a conveying pipe, a collection hopper connected to the right end of the conveying pipe, a suction fan on the conveying pipe, a collection bin at the bottom of the collection hopper, and a fixed base connected to the outside of the collection hopper.

[0007] Preferably, the elastic component includes a plurality of hinges connected to the conveyor, each hinge having a spring connected to it, and the end of each spring furthest from the conveyor is also connected to the frame via a hinge.

[0008] Preferably, each spring has a sleeve and a guide post inside, each guide post is located inside the corresponding sleeve and the two are slidably connected, and each sleeve and guide post are fixedly connected to the adjacent hinge.

[0009] Preferably, the material pipe includes a main material pipe and a telescopic pipe, the telescopic pipe is located below the main material pipe and the two are slidably connected, the width of the telescopic pipe is the same as the width of the conveyor, the main material pipe is provided with a telescopic rod, and the output end of the telescopic rod is connected to the telescopic pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the synergistic effect of multiple sets of annularly distributed dispersing plates and hot air, raw material agglomeration can be effectively broken up, ensuring uniform dispersion and providing a good foundation for subsequent drying processes, thus avoiding drying dead zones caused by agglomeration. The vibrating conveyor, combined with elastic components, keeps the raw materials in a dispersed and tumbling state during transport, significantly increasing the contact area with hot air; the inclined design extends the drying path, ensuring hot air acts evenly on the raw materials, significantly improving drying efficiency and uniformity, and reducing fluctuations in residual moisture.

[0011] II. The spring and guide column combination in the elastic component not only meets the requirements of vibration conveying but also effectively limits lateral deviation, reducing equipment vibration noise and component wear. The telescopic material tube can flexibly adjust its distance from the conveyor to adapt to raw material layers of different thicknesses; the suction fan provides stable negative pressure to ensure that the raw material completely enters the receiving channel, reducing residual waste and avoiding channel blockage.

[0017] Please see Figures 1-5 This utility model provides an embodiment: a drying device for synthetic diamond raw materials, including a dispersing box 1, a drying box 2 at the bottom of the dispersing box 1, and a receiving component 4 on the right side of the drying box 2. The dispersing box 1 is located at the top of the drying box 2 and communicates with it, and is used to pre-disperse and initially dry the agglomerated synthetic diamond raw materials. The drying box 2 is used to perform deep drying of the raw materials. The receiving component 4 is connected to the right side of the drying box 2 and is used to collect the dried raw materials.

[0018] The dispersing box 1 includes a hopper 11. The top of the hopper 11 is provided with a feed inlet, and the bottom is connected to the drying box 2 through a discharge channel. The left and right side walls of the hopper 11 are provided with filter screens 14 with a mesh size of 0.5-1mm, which are used to filter dust and impurities in the raw materials. An impurity collection box (not shown in the figure) can be provided outside the filter screen 14 on the right side.

[0019] A first fan 12 is provided on the left side of the hopper 11. The first fan is a hot air fan with the air outlet tilted upward at 45° towards the inside of the hopper. The inside of the hopper 11 is provided with multiple dispersing plates 13. The dispersing plates are made of wear-resistant stainless steel and have anti-slip textures on the surface. The rear end of the hopper 11 is provided with a drive motor of model Y2-90L-4. The output shaft of the drive motor is located inside the hopper 11. The multiple dispersing plates 13 are evenly connected in a ring on the output shaft of the drive motor.

[0020] The drying chamber 2 is equipped with a frame 21 inside. The bottom of the hopper 11 is equipped with a conveyor 22. The conveyor is a mesh belt vibrating conveyor with a mesh belt aperture of 0.3-0.5mm to prevent material leakage. The conveyor 22 is placed at an angle with the left end higher than the right end, and the angle of inclination is 15-30°. The conveyor 22 is connected to the frame 21 by an elastic component 3. The conveyor 22 is equipped with a YZO-10-2 vibrating motor 24. The bottom of the frame 21 is equipped with a second fan 23, which is a hot air fan. The air outlet is equipped with a flow equalization plate to ensure that the hot air is blown evenly onto the conveyor mesh belt.

[0021] The elastic component 3 includes multiple hinges 31 connected to the conveyor 22, which are symmetrically distributed on the front and rear sides of the conveyor 22. Each hinge 31 is connected to a spring 32. The end of each spring 32 away from the conveyor 22 is also connected to the frame 21 through the hinge 31. Each spring 32 has a sleeve 33 and a guide post 34 inside. The diameter of the guide post 34 is 0.5-1mm smaller than the inner diameter of the sleeve 33, and the guide post 34 is slidably embedded in the sleeve 33. The top of the sleeve 33 is welded to the hinge 31 on the conveyor side, and the bottom of the guide post 34 is welded to the hinge 31 on the frame side, which limits the lateral displacement of the spring.

[0022] The receiving assembly 4 includes a material pipe 41, the top of which is connected to a conveying pipe 42. The right end of the conveying pipe 42 is connected to a collecting hopper 44, which is inverted conical in shape. The bottom of the collecting hopper 44 is connected to the collecting bin 45 through a gate valve. A suction fan 43 is provided on the conveying pipe 42. The outside of the collecting hopper 44 is connected to a fixed base 46, which is fixed to the ground by expansion bolts.

[0023] Furthermore, the material pipe 41 includes a main material pipe 411 and a telescopic pipe 412. The telescopic pipe 412 is located below the main material pipe 411 and the two are slidably connected. The width of the telescopic pipe 412 is the same as the width of the mesh belt of the conveyor 22. The main material pipe 411 is provided with a telescopic rod 413. The output end of the telescopic rod 413 is connected to the telescopic pipe 412. The distance between the telescopic pipe 412 and the conveyor 22 can be adjusted by the control system.

[0024] Working principle of this utility model: 1. After the artificial diamond raw material is fed into the feed port at the top of the hopper 11, the drive motor drives the dispersing plate 13 to rotate at high speed to mechanically disperse the clumped raw material; at the same time, the first blower 12 blows hot air into the hopper to help disperse the raw material on the one hand, and initially evaporate the surface moisture on the other hand, and the dust and impurities are discharged through the filter screen 14.

[0025] 2. After being dispersed, the raw materials enter the conveyor belt of the drying chamber 2 through the material drop channel. The vibrating motor 24 drives the conveyor to vibrate. With the buffering effect of the elastic component 3, the raw materials continue to roll and disperse during the inclined conveying process. The second fan 23 at the bottom of the frame 21 blows hot air upward. The hot air passes through the mesh belt and comes into full contact with the dispersed raw materials to deeply evaporate the moisture and complete the drying process.

[0026] 3. The dried raw material is conveyed to the right end by the conveyor 22 and falls into the material pipe 41 (the height of the telescopic pipe 412 is adjusted by the telescopic rod 413 to ensure that the raw material is fully entered); the suction fan 43 generates negative pressure in the conveying pipe 42, sucking the raw material into the collection hopper 44, and then falling into the collection bin 45 for storage under the control of the gate valve, thus completing the entire drying-collection process.

[0027] 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.
