Description

Technical Field

[0001] The utility model belongs to the technical field of nitriding alloys, and in particular relates to a nitriding alloy powder separator. Background Art

[0002] Nitride alloy powder is a powder material formed by combining metal or non-metal elements with nitrogen. This type of material usually has high hardness, good wear resistance, heat resistance and good chemical stability. At present, after the nitride alloy powder is produced, it needs to be sorted by a special nitride alloy powder sorting machine;

[0003] Traditionally, these powder classifiers achieve continuous operation by directly connecting to the discharge port of the external powder storage area. Although this method achieves the basic needs of sorting, it exposes several disadvantages in actual operation. When the feed amount is large, the nitride alloy powder is prone to arching and aggregation due to the characteristics of its own material. This not only significantly reduces the flowability of the powder, but also directly causes the blockage of the powder classifier feed pipeline. The pipeline blockage not only reduces the working efficiency of the equipment, but also affects the stability and continuity of the overall operation. Utility Model Content

[0004] In view of this, the utility model provides a nitride alloy powder classifier, which can prevent large or adhered powders from clogging the pipeline through an anti-clogging mechanism, and can also avoid the arching phenomenon during the transportation of nitride alloy powders, thereby improving the fluidity of nitride alloy powders, further reducing the possibility of clogging, effectively solving the clogging problem in the material transportation process, and improving the working efficiency and stability of the equipment.

[0005] In order to solve the above technical problems, the utility model provides a nitride alloy powder classifier, including a powder classifier body and a feed pipe arranged at the feed port at the upper right end of the powder classifier body, an anti-blocking mechanism is arranged in the feed pipe, the anti-blocking mechanism includes a fixed frame arranged in the middle of the inner cavity of the feed pipe, a sliding rod is slidably connected in a sliding hole arranged in the middle of the upper end surface of the fixed frame, a lifting head is arranged at the upper end of the sliding rod, a rotating rod is rotatably connected in a rotating hole arranged in the middle of the rear end of the fixed frame, an eccentric wheel is arranged at the front end of the rotating rod, the eccentric wheel and the sliding rod are cooperatively arranged, and an auxiliary component is also arranged between the eccentric wheel and the rotating rod.

[0006] The anti-blocking mechanism also includes an annular plate arranged at the lower end of the outer arc surface of the sliding rod, a spring is arranged between the upper end surface of the annular plate and the top wall surface of the fixed frame, and the spring is movably sleeved on the outside of the sliding rod; the anti-blocking mechanism also includes a motor arranged at the rear end of the outer arc surface of the feed pipe, and the front end of the output shaft of the motor passes through a through opening arranged in the middle part of the rear end of the outer arc surface of the feed pipe and is fixedly connected to the rear end of the rotating rod.

[0007] The auxiliary component includes a ball groove arranged on the lower end surface of the sliding rod, in which a rotating ball is rotatably connected, and the rotating ball is matched with the eccentric wheel; the auxiliary component also includes an annular ball groove arranged on the outer arc surface of the eccentric wheel, and the annular ball groove is matched with the rotating ball.

[0008] The upper end of the inner arc surface of the ejecting head is provided with a vibrating motor which is symmetrically distributed laterally.

[0009] The powder selection machine body, the motor and the vibration motor are all electrically connected to the external single chip microcomputer.

[0010] The beneficial effects of the above technical solution of the utility model are as follows:

[0011] 1. The relevant operator connects the feed pipe with the discharge port of the external nitride alloy powder production site, and then the relevant operator controls the powder selection body, motor and vibration motor to operate synchronously through the external single-chip computer. In the process of the nitride alloy powder entering the powder selection body through the feed pipe, the motor output shaft rotates to drive the rotating rod and the eccentric wheel to rotate synchronously. When the eccentric wheel is away from the center end and cooperates with the sliding rod, the sliding rod, the ejector head and the annular plate overcome the elastic force of the spring and move upward. When the eccentric wheel is away from the center end and separated from the sliding rod, the sliding rod, the ejector head and the annular plate move downward under the action of the spring rebound force. During the uniform rotation of the eccentric wheel, the sliding rod, the ejector head and the annular plate move back and forth up and down, which can continuously disturb the material in the feed pipe to prevent large pieces or adhesions of powder from clogging the pipeline, and can also avoid the phenomenon of arching during the transportation of nitride alloy powder.

[0012] 2. When the vibration motor is working, the vibration wave generated can be transmitted to the top head, making the nitride alloy powder at the top head looser under the action of vibration, improving the fluidity of the nitride alloy powder, further reducing the possibility of blockage, effectively solving the blockage problem in the material transportation process, and improving the working efficiency and stability of the equipment.

[0013] 3. The rotating ball greatly reduces the friction between the eccentric wheel and the rotating rod, ensuring the smoothness of both during movement. Secondly, the annular ball groove ensures the stability of the rotating ball. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] like Figure 1-4 As shown:

[0021] The present embodiment provides a nitride alloy powder classifier, including a powder classifier body 100 and a feed pipe 200 arranged at a feed port at the upper right end of the powder classifier body 100, wherein an anti-blocking mechanism is arranged in the feed pipe 200, and the anti-blocking mechanism comprises a fixed frame 201 arranged in the middle of the inner cavity of the feed pipe 200, a sliding rod 202 is slidably connected in a sliding hole arranged in the middle of the upper end surface of the fixed frame 201, a top head 203 is arranged at the upper end of the sliding rod 202, a rotating rod 204 is rotatably connected in a rotating hole arranged in the middle of the rear end of the fixed frame 201, an eccentric wheel 205 is arranged at the front end of the rotating rod 204, and the eccentric wheel 20 5 is arranged in cooperation with the sliding rod 202, and an auxiliary component is also arranged between the eccentric wheel 205 and the rotating rod 204; the anti-blocking mechanism also includes an annular plate 206 arranged at the lower end of the outer arc surface of the sliding rod 202, and a spring 207 is arranged between the upper end surface of the annular plate 206 and the top wall surface of the fixing frame 201, and the spring 207 is movably sleeved with the outer part of the sliding rod 202; the anti-blocking mechanism also includes a motor 208 arranged at the rear end of the outer arc surface of the feeding pipe 200, and the front end of the output shaft of the motor 208 passes through the through hole arranged in the middle part of the rear end of the outer arc surface of the feeding pipe 200 and is fixedly connected to the rear end of the rotating rod 204.

[0022] like Figure 2-4 As shown, the upper end of the inner arc surface of the ejecting head 203 is provided with a vibration motor 400 which is symmetrically distributed laterally.

[0023] like Figure 1-4 As shown, the powder selection machine body 100, the motor 208 and the vibration motor 400 are all electrically connected to an external single chip microcomputer.

[0024] The working principle of the nitride alloy powder classifier provided by the utility model is as follows: the relevant operator connects the feed pipe 200 with the discharge port of the external nitride alloy powder production site, and then the relevant operator controls the powder classifier body 100, the motor 208 and the vibration motor 400 to operate synchronously through the external single-chip computer. When the nitride alloy powder enters the powder classifier body 100 through the feed pipe 200, the output shaft of the motor 208 rotates to drive the rotating rod 204 and the eccentric wheel 205 to rotate synchronously. The eccentric wheel 205 is away from the center end and the sliding rod 202 is moved. When the eccentric wheel 205 is in the process of rotating at a constant speed, the sliding rod 202, the ejecting head 203 and the annular plate 206 move up and down, which can continuously disturb the material in the feeding pipe 200, prevent large pieces or sticky powder from clogging the pipe, and also can To avoid the phenomenon of arching during the transportation of nitride alloy powder, when the vibration motor 400 is working, the vibration wave generated can be transmitted to the top head 203, so that the nitride alloy powder at the top head 203 becomes looser under the action of vibration, the fluidity of the nitride alloy powder is improved, the possibility of blockage is further reduced, the blockage problem in the material transportation process is effectively solved, and the working efficiency and stability of the equipment are improved. The nitride alloy powder entering the powder selection body 100 generates a strong centrifugal force by the high-speed rotating cage, which disperses and accelerates the nitride alloy powder. At the same time, the external fan pumps gas into the powder selection body 100, so that the nitride alloy powder particles begin to separate according to their own particle size and density differences. The fine particles are more easily carried up by the rising airflow due to the large drag of the airflow and discharged from the upper opening. The relatively large particles are more obviously affected by the centrifugal force due to their large mass and cannot be fully carried away by the rising airflow, but slide down along the wall of the powder selection body 100 and are discharged. The fineness and output of the product can be controlled by adjusting parameters such as wind speed and rotation speed to achieve efficient classification of materials.

[0025] like Figure 2-4 As shown, the auxiliary component includes a ball groove arranged on the lower end surface of the sliding rod 202, in which a rotating ball 300 is rotatably connected, and the rotating ball 300 is arranged in cooperation with the eccentric wheel 205; the auxiliary component also includes an annular ball groove 301 arranged on the outer arc surface of the eccentric wheel 205, and the annular ball groove 301 is arranged in cooperation with the rotating ball 300. The rotating ball 300 greatly reduces the friction between the eccentric wheel 205 and the rotating rod 204, ensuring the smoothness of the two during movement. Secondly, the annular ball groove 301 ensures the stability of the operation of the rotating ball 300.

[0026] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
