Description

Technical Field

[0001] The present invention relates to the technical field of carbonylation metallurgy, and particularly to an anti-blocking valve for the production of carbonylation metallurgy nickel pellets. Background Art

[0002] In the production process of carbonylation metallurgy nickel pellets, granular nickel pellets are transported through process pipelines. The particle size distribution of nickel pellet particles is relatively wide, covering various particle sizes within the range of 0 - 15 mm. Also transported together with the nickel pellet particles in the process pipeline is highly toxic carbonyl gas. During the production process, it is found that the valves of the pipeline are often blocked by nickel pellet particles of different sizes, resulting in the valves being unable to be opened or closed normally, seriously affecting normal production operations. In the production process of carbonylation metallurgy nickel pellets, anti-blocking valves are very important equipment because they can prevent blockage problems during production and ensure the smooth progress of production.

[0003] As disclosed in a Chinese patent CN219734259U, an anti-blocking valve for the production of carbonylation metallurgy nickel pellets, a valve plate perpendicular to the material flow direction is provided in the anti-blocking valve. The movable valve plate is used to block the transmission path of the metal material, effectively protecting the rear valve and preventing the rear valve from being blocked by the metal material, resulting in problems such as being unable to be closed or opened.

[0004] For this structure, although it can prevent blockage by blocking the transmission of metal materials, during the transportation process of the materials, blockage will occur, and it is inconvenient to prevent blockage for this valve. Therefore, we propose an anti-blocking valve for the production of carbonylation metallurgy nickel pellets that can prevent blockage of the materials during the transportation process to improve production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-blocking valve for the production of carbonylation metallurgy nickel pellets to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An anti-blocking valve for the production of carbonylation metallurgy nickel pellets, including a valve body. A placement frame is fixedly installed on the outer wall of the valve body. A connecting pipe is provided at the end of the valve body, and a processing assembly is provided outside the connecting pipe. The processing assembly includes a turning assembly provided inside the valve body, a partition assembly provided at the end of the turning assembly, and a sealing assembly provided outside the partition assembly.

[0007] Preferably, the turning assembly includes a bracket provided inside the valve body. A motor is fixedly installed on the inner wall of the bracket. A rotating rod is fixedly installed at the output end of the motor. A sleeve is fixedly installed on the outer wall of the rotating rod. A spring is provided inside the sleeve. A limit ring is fixedly installed at the end of the spring. A sliding rod is fixedly installed on the side of the limit ring away from the spring. An arc plate is fixedly installed at the end of the sliding rod away from the limit ring.

[0008] Preferably, the partition assembly includes a telescopic rod fixedly installed at one end of the motor away from the rotating rod. A partition disk is slidably arranged inside the placement frame, and a blocking disk is fixedly installed on the outer wall of the partition disk.

[0009] Preferably, the sealing assembly includes an annular groove opened at the end of the valve body. A first sealing ring is fixedly installed on the inner wall of the annular groove. An installation ring is fixedly installed at the end of the connecting pipe, and a second sealing ring is fixedly installed on the side of the installation ring away from the connecting pipe.

[0010] Preferably, the outer wall of the arc plate is arc-shaped. The outer wall of the rotating rod is rotatably connected to the inside of the bracket. Under the restriction of the arc plate with an arc-shaped outer wall, it can smoothly slide into the cylindrical chamber inside the valve body. Supported by the bracket, the rotating rod can rotate stably.

[0011] Preferably, one end of the spring is fixedly installed inside the sleeve, and the end of the spring away from the inside of the sleeve is fixedly installed on the side of the limiting ring away from the sliding rod. Under the elastic action of the spring, the arc plate that is not squeezed is pushed back to prevent blockage of the carbonylated metallurgical nickel pellets inside the valve body.

[0012] Preferably, the side of the blocking disk away from the partition disk is rotatably connected to the end of the rotating rod away from the motor. The blocking disk is slidably arranged inside the valve body. Under the restriction of the blocking disk and the partition disk, the valve body can be closed.

[0013] Preferably, the second sealing ring and the first sealing ring are made of rubber. The installation ring and the annular groove are sleeved. Under the restriction of the rubber second sealing ring and the first sealing ring, the connection between the connecting pipe and the valve body can be sealed.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The anti-blocking valve for the production of carbonylated metallurgical nickel pellets includes a flipping component as one of its parts. When transporting the carbonylated metallurgical nickel pellets, to prevent them from blocking the valve body, at this time, the telescopic rod is used to push the flipping component towards the middle of the pipe body. Then the motor is started, and the rotating rod fixedly installed at its output end rotates accordingly. Since the outer wall of the rotating rod is rotatably connected to the inside of the bracket, supported by the bracket, the rotating rod can rotate stably. The rotating rod drives the sleeve fixedly installed on its outer wall to rotate accordingly. The sleeve drives the limiting ring and the sliding rod slidably arranged inside it to rotate, so that the sliding rod cooperates with the arc plate to flip the carbonylated metallurgical nickel pellets inside the valve body. When the carbonylated metallurgical nickel pellets are squeezed against the arc plate, the arc plate drives the sliding rod to slide towards the sleeve direction, and compresses the spring through the limiting ring. When the arc plate is no longer squeezed, under the elastic action of the spring, the limiting ring, the sliding rod and the arc plate are pushed to generate a vibration sensation to assist in preventing blockage during the transportation of the carbonylated metallurgical nickel pellets. This structure can prevent the carbonylated metallurgical nickel pellets from blocking inside the valve body, thereby improving production efficiency.

[0016] 2. The anti-blocking valve for the production of carbonylated metallurgical nickel pellets has a partition component as one of its parts. After the carbonylated metallurgical nickel pellets are transported, the valve body needs to be closed. At this time, the telescopic rod is activated, which pulls the entire turning component. The rotating rod drives the movement of the baffle plate rotatably connected to the end away from the motor, causing the partition plate to slide towards the outside of the placement frame. The partition plate seals the inside of the valve body, and the baffle plate seals the chamber where the turning component is placed, so as to close the valve body and isolate the carbonylated metallurgical nickel pellets from the toxic gas.

[0017] 3. The anti-blocking valve for the production of carbonylated metallurgical nickel pellets has a sealing component as one of its parts. When transporting the carbonylated metallurgical nickel pellets, the valve body and the connecting pipe are installed by bolts. The mounting ring fixedly installed at the end of the connecting pipe and the second sealing ring are sleeved inside the circular groove, so that the second sealing ring is pressed against the first sealing ring to seal the connection between the connecting pipe and the valve body, preventing the leakage of carbonylated metallurgical nickel pellets and toxic gas. This structure can seal the connecting pipe and the valve body to improve the transportation effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0027] In order to have a clearer understanding of the technical features, objectives, and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0028] Example 1: A preferred embodiment of an anti-blocking valve for the production of carbonylated metallurgical nickel pellets provided by the present invention is as Figures 1 to 8 shown: An anti-blocking valve for the production of carbonylated metallurgical nickel pellets includes a valve body 1;

[0029] A placement frame 2 is fixedly installed on the outer wall of the valve body 1;

[0030] A connecting pipe 3 is provided at the end of the valve body 1;

[0031] And a processing assembly 4 provided outside the connecting pipe 3. The processing assembly 4 includes a turning assembly 41 provided inside the valve body 1. The turning assembly 41 includes a bracket 411 provided inside the valve body 1. A motor 412 is fixedly installed on the inner wall of the bracket 411. A rotating rod 413 is fixedly installed at the output end of the motor 412. A sleeve 414 is fixedly installed on the outer wall of the rotating rod 413. A spring 415 is provided inside the sleeve 414. A limiting ring 416 is fixedly installed at the end of the spring 415. A sliding rod 417 is fixedly installed on the side of the limiting ring 416 away from the spring 415. An arc plate 418 is fixedly installed at the end of the sliding rod 417 away from the limiting ring 416.

[0032] In this embodiment, when transporting the carbonylated metallurgical nickel pellets, in order to prevent them from blocking the valve body 1, at this time, the turning assembly 41 is pushed towards the middle of the pipe body by the telescopic rod 421. At this time, the motor 412 is started, and the rotating rod 413 fixedly installed at its output end rotates accordingly. Since the outer wall of the rotating rod 413 is rotatably connected to the inside of the bracket 411, under the support of the bracket 411, the rotating rod 413 can rotate stably. The rotating rotating rod 413 drives the sleeve 414 fixedly installed on its outer wall to rotate accordingly. The sleeve 414 drives the limiting ring 416 and the sliding rod 417 slidably arranged inside it to rotate, so that the sliding rod 417 cooperates with the arc plate 418 to turn the carbonylated metallurgical nickel pellets inside the valve body 1. When the carbonylated metallurgical nickel pellets are squeezed against the arc plate 418, the arc plate 418 drives the sliding rod 417 to slide towards the sleeve 414, and compresses the spring 415 through the limiting ring 416. When the arc plate 418 is no longer squeezed, under the elastic action of the spring 415, the limiting ring 416, the sliding rod 417, and the arc plate 418 are pushed to generate a shock feeling, providing anti-blocking assistance for the transportation of the carbonylated metallurgical nickel pellets. This structure can prevent the carbonylated metallurgical nickel pellets from blocking inside the valve body 1, thereby improving production efficiency.

[0033] Example 2: On the basis of Example 1, a preferred embodiment of an anti-blocking valve for the production of carbonylated metallurgical nickel pellets provided by the present invention is as Figures 1 to 8As shown: The partition assembly 42 includes a telescopic rod 421 fixedly installed at one end of the motor 412 away from the rotating rod 413. A partition disc 423 is slidably arranged inside the placement frame 2, and a retaining disc 422 is fixedly installed on the outer wall of the partition disc 423.

[0034] In this embodiment, after the carbonylated metallurgical nickel pellets are transported, the valve body 1 needs to be closed. At this time, the telescopic rod 421 is started, which pulls the entire turning assembly 41. The rotating rod 413 drives the movement of the retaining disc 422 rotatably connected to its end away from the motor 412, causing the partition disc 423 to slide towards the outside of the placement frame 2. The partition disc 423 seals the inside of the valve body 1, and the retaining disc 422 seals the chamber where the turning assembly 41 is placed, so as to close the valve body 1 and isolate the carbonylated metallurgical nickel pellets from the toxic gas.

[0035] Embodiment 3: On the basis of Embodiment 1, a preferred embodiment of an anti-blocking valve for producing carbonylated metallurgical nickel pellets provided by the present invention is as Figures 1 to 8 As shown: The sealing assembly 43 includes an annular groove 431 opened at the end of the valve body 1. A first sealing ring 432 is fixedly installed on the inner wall of the annular groove 431. An installation ring 433 is fixedly installed at the end of the connecting pipe 3. A second sealing ring 434 is fixedly installed on the side of the installation ring 433 away from the connecting pipe 3.

[0036] In this embodiment, when transporting the carbonylated metallurgical nickel pellets, the valve body 1 and the connecting pipe 3 are installed by bolts. The installation ring 433 fixedly installed at the end of the connecting pipe 3 and the second sealing ring 434 are sleeved inside the annular groove 431, so that the second sealing ring 434 is pressed against the first sealing ring 432 to seal the connection between the connecting pipe 3 and the valve body 1, avoiding the leakage of carbonylated metallurgical nickel pellets and toxic gas. This structure can seal the connecting pipe 3 and the valve body 1 to improve the transportation effect.

[0037] Furthermore, the outer wall of the arc plate 418 is arranged in an arc shape. The outer wall of the rotating rod 413 is rotatably connected to the inside of the bracket 411. Under the restriction of the arc plate 418 arranged in an arc shape, it can smoothly slide into the cylindrical chamber inside the valve body 1. Supported by the bracket 411, the rotating rod 413 can rotate stably. One end of the spring 415 is fixedly installed inside the sleeve 414, and the end of the spring 415 away from the inside of the sleeve 414 is fixedly installed on the side of the limiting ring 416 away from the sliding rod 417. Under the elastic action of the spring 415, the arc plate 418 not under extrusion is pushed to reset to prevent blockage of the carbonylated metallurgical nickel pellets inside the valve body 1.

[0038] Even further, the side of the retaining disc 422 away from the partition disc 423 is rotatably connected to the end of the rotating rod 413 away from the motor 412. The retaining disc 422 is slidably arranged inside the valve body 1. Under the restriction of the retaining disc 422 and the partition disc 423, the valve body 1 can be closed.

[0039] In addition, the second sealing ring 434 and the first sealing ring 432 are made of rubber. The mounting ring 433 is sleeved inside the annular groove 431. Under the limitation of the rubber second sealing ring 434 and the first sealing ring 432, the connection between the connecting pipe 3 and the valve body 1 can be sealed.

[0040] The above is only a schematic specific embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the scope of protection of the present invention. Moreover, it should be noted that the components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be selected and used alone according to actual needs or multiple features can be combined for use. Therefore, the present invention should logically cover other combinations and specific applications related to the inventive points of this case.
