Description

Technical Field

[0001] This utility model relates to the field of diamond micron powder production, and more specifically, to a settling device for diamond micron powder production. Background Technology

[0002] Diamond micron powder, a fine superhard abrasive, refers to diamond particles with a size finer than 54 micrometers. Among them, single-crystal diamond micron powder has attracted much attention due to its large production volume and wide application. It is produced by crushing and shaping synthetic single-crystal diamond abrasive grains through hydrostatic pressing, using special processes for superhard materials. With its high hardness and good wear resistance, it is widely used in cutting, grinding, drilling, polishing and other fields. It is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, and optical glass. In the production process of diamond micron powder, particle size classification is a crucial step. Its main purpose is to concentrate the particle size distribution as much as possible and completely eliminate oversized particles.

[0003] Chinese utility model patent CN222035158U discloses a diamond micron powder settling device. In use, this device, through the coordinated action of a drive motor, support plate, mounting plate, positioning column, sliding ring, support rod, positioning block, limiting hole, connecting rod, feeding hopper, support hole, mounting column, feeding plate, and scraper, agitates the diamond micron powder inside the feeding hopper, allowing it to continuously enter the settling tank through the connecting hole. This enables the diamond micron powder to quickly combine with the water inside the settling tank and settle, achieving the desired feeding effect and facilitating the settling of diamond micron powder by operators. However, during the feeding of diamond micron powder, the combined action of the scraper and feeding plate easily allows the diamond micron powder to pass through the support hole and the material portion of the feeding hopper, scattering it into the air and causing dust spillage, which poses health risks to operators and pollutes the environment.

[0004] Therefore, it is necessary to redesign the settling device for diamond micron powder production to address the aforementioned issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, embodiments of this utility model provide a settling device for diamond micron powder production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A settling device for diamond micron powder production includes a settling box and a feeding box. The feeding box is fixedly installed on the upper end face of the settling box. A cover plate is fixedly installed on the upper end face of the feeding box. A sliding groove is formed on the upper end face of the cover plate, and an installation groove is formed on the lower end face of the cover plate. The installation groove communicates with the sliding groove. A transmission device is provided in the installation groove. Two connecting rods are symmetrically fixedly connected to the output end of the transmission device. A connecting plate is fixedly connected to the bottom end of each connecting rod, and both connecting plates are in contact with the inner bottom wall of the feeding box. Multiple connecting grooves are equidistantly formed on the inner bottom wall of the feeding box, and the multiple connecting grooves communicate with the settling box respectively.

[0008] In a preferred embodiment, the transmission device includes two springs, which are symmetrically fixedly installed on the inner sidewall of the mounting groove. One end of each spring is fixedly connected to a mounting block, and the mounting block slides in the mounting groove. Two connecting rods are fixedly connected to the bottom end of the mounting block. A rack is fixedly installed on the upper surface of the mounting block, and the rack is located in the sliding groove.

[0009] In a preferred embodiment, a mounting bracket is fixedly installed on the upper end face of the cover plate, a motor is fixedly installed on the mounting bracket, and a half gear is fixedly installed on the output shaft of the motor, and the half gear meshes with a rack.

[0010] In a preferred embodiment, two limiting rods are symmetrically fixedly installed on the inner sidewall of the mounting groove, and the mounting block is slidably sleeved on the outer wall of the two limiting rods.

[0011] In a preferred embodiment, elastic protective membranes are fixedly connected to both sides of the mounting block, and the ends of the two elastic protective membranes away from the mounting block are fixedly connected to the inner sidewall of the mounting groove.

[0012] In a preferred embodiment, two scrapers are symmetrically fixedly connected to the upper end face of each of the connecting plates, and the scrapers are in contact with the inner side wall of the feeding box.

[0013] In a preferred embodiment, a feeding pipe is fixedly installed on the upper end face of the cover plate, and the feeding pipe is connected to the feeding box.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model uses a motor, a half gear, a transmission device, etc. The motor drives the half gear and the rack to mesh periodically, driving the connecting plate and scraper to make reciprocating linear motion in the feeding box, which fully stirs the diamond powder suspension. This effectively prevents the diamond powder particles from entering the settling box in large quantities at once and agglomerating, so that the powder reaches a uniformly dispersed state before entering the settling box.

[0016] 2. This utility model incorporates an elastic protective film, a cover plate, and a scraper. The scraper's design, which closely adheres to the box wall, promptly removes micro-powder adhering to the inner wall and bottom of the feeding box, preventing micro-powder accumulation from affecting the grading effect. The elastic protective film on both sides of the mounting block seals the gap between the mounting block and the mounting groove. Combined with the cover plate's sealing effect on the box, this double protection effectively prevents diamond powder from splashing out and drifting into the external environment, reducing the risk of operators inhaling dust, reducing dust concentration in the workshop, and preventing dust pollution of the environment.

[0017] In summary, this utility model is simple to operate. The motor drives the half gear and rack to mesh, causing the connecting plate and scraper to reciprocate, which fully stirs the diamond powder, prevents the diamond powder from agglomerating, and allows the micro powder to be evenly dispersed before entering the settling tank, thus improving the grading efficiency and accuracy. At the same time, the scraper scrapes off the micro powder from the tank wall, and the elastic protective film and cover plate provide double sealing to prevent dust from splashing and spreading, reduce the risk of inhalation, reduce pollution, and enhance safety and environmental protection.

[0025] 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.

[0026] Reference Figure 1-6 A settling device for diamond micron powder production includes a settling box 1 and a feeding box 2. The feeding box 2 is fixedly installed on the upper end face of the settling box 1. A cover plate 3 is fixedly installed on the upper end face of the feeding box 2. A sliding groove 6 is opened on the upper end face of the cover plate 3. An installation groove 17 is opened on the lower end face of the cover plate 3, and the installation groove 17 communicates with the sliding groove 6. A transmission device is installed in the installation groove 17. Two connecting rods 12 are symmetrically fixedly connected to the output end of the transmission device. A connecting plate 13 is fixedly connected to the bottom end of each connecting rod 12. Both connecting plates 13 are in contact with the inner bottom wall of the feeding box 2. Multiple connecting grooves 9 are equidistantly opened on the inner bottom wall of the feeding box 2, and the multiple connecting grooves 9 are respectively connected to the settling box 1.

[0027] The transmission device includes two springs 16, which are symmetrically fixedly installed on the inner wall of the mounting groove 17. One end of the two springs 16 is fixedly connected to the mounting block 11, and the sliding rod of the mounting block 11 is connected in the mounting groove 17. Two connecting rods 12 are fixedly connected to the bottom end of the mounting block 11. A rack 8 is fixedly installed on the upper end face of the mounting block 11, and the rack 8 is located in the sliding groove 6. A mounting bracket 5 is fixedly installed on the upper end face of the cover plate 3. A motor 4 is fixedly installed on the mounting bracket 5. A half gear 18 is fixedly installed on the output shaft of the motor 4, and the half gear 18 meshes with the rack 8. When the half gear 18 disengages from the rack 8, the springs 16 use their own elastic restoring force to push the mounting block 11 to move in the opposite direction, so that the connecting plate 13 and the scraper 14 can achieve reciprocating cyclic action.

[0028] Two limiting rods 15 are symmetrically fixedly installed on the inner side wall of the mounting groove 17, and the mounting block 11 is slidably sleeved on the outer wall of the two limiting rods 15. The two limiting rods 15 restrict the movement direction of the mounting block 11, ensuring that the mounting block 11 slides only in a straight line in the horizontal direction, preventing transmission failure or component collision caused by offset.

[0029] Elastic protective films 10 are fixedly connected to both sides of the mounting block 11, and the ends of the two elastic protective films 10 away from the mounting block 11 are fixedly connected to the inner sidewall of the mounting groove 17. The elastic protective films 10 can effectively prevent diamond powder from drifting to the outside through the mounting groove 17.

[0030] Two scrapers 14 are symmetrically fixed to the upper end face of each connecting plate 13, and the scrapers 14 are in contact with the inner side wall of the feeding box 2. The scrapers 14 can scrape off the diamond powder on both sides of the feeding box 2.

[0031] A feeding pipe 7 is fixedly installed on the upper end face of the cover plate 3, and the feeding pipe 7 is connected to the feeding box 2, so that diamond micro powder can be transported to the feeding box 2 through the feeding pipe 7.

[0032] When this utility model is in use, the motor 4 starts, driving the half gear 18 to rotate. Since only a portion of the half gear 18 has teeth, it periodically meshes with the rack 8 on the upper surface of the mounting block 11 during rotation. According to the gear and rack transmission principle, when the half gear 18 meshes with the rack 8, it pushes the mounting block 11 to slide horizontally within the mounting groove 17. Two limiting rods 15, symmetrically fixed to the inner sidewall of the mounting groove 17, are sleeved on the mounting block 11, restricting its direction of movement and ensuring that the mounting block 11 can only move in a straight line in the horizontal direction. The mounting block 11 is connected to the connecting plate 13 below through two connecting rods 12. Therefore, the horizontal movement of the mounting block 11 will drive the connecting plate 13 to make a horizontal reciprocating linear movement within the feeding box 2.

[0033] The scraper 14 fixed on the connecting plate 13 is in contact with the inner wall of the feeding box 2. When the connecting plate 13 is driven by the driving device to make reciprocating linear motion, the scraper 14 simultaneously scrapes the inner wall of the box. On the one hand, the movement of the scraper 14 and the connecting plate 13 continuously stirs the diamond powder in the feeding box 2, promotes particle dispersion and avoids agglomeration. On the other hand, the two are in close contact with the box wall, which can scrape off the powder adhering to the inner wall and bottom of the feeding box 2, preventing accumulation and interference with grading. In addition, the elastic protective film 10 on both sides of the mounting block 11 seals the gap between the mounting block 11 and the mounting groove 17, preventing diamond powder from splashing out through the mounting groove 17 and the sliding groove 6. The cover plate 3, as the closed structure of the feeding box 2, can prevent external dust from mixing in and further suppress diamond powder from drifting to the external environment.

[0034] Multiple connecting grooves 9 are evenly spaced on the inner bottom wall of the feeding box 2, and each of the multiple connecting grooves 9 is connected to the settling box 1. The diamond powder, after being reciprocated, flows into the settling box 1 through the connecting grooves 9.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
