Technical Field

[0001] The utility model belongs to the technical field of nitriding alloy production, and specifically relates to a protective device for nitriding alloy production. Background Art

[0002] Nitriding alloy is a compound material formed by combining metal with nitrogen. At present, nitriding alloy needs to be crushed by special crushing equipment during processing to obtain the finished product with the required particle size.

[0003] At present, when crushing equipment is processing nitride alloys, its open feed port structure causes fine nitride alloy fragments to be easily scattered outward during the crushing operation, which not only causes material loss but also causes problems with the working environment. When operators approach the open feed area to add materials, they are not only directly exposed to possible flying alloy debris, but also inhale the dusty gas generated during the operation. This situation seriously threatens the safety of operators during operation. Utility Model Content

[0004] In view of this, the utility model provides a protective device for nitriding alloy production, which can effectively prevent the leakage of dust-containing gas that may be generated in the production of nitriding alloy through the protective mechanism, avoid the escape of flying alloy debris from the feed pipe, ensure the safety of nitriding alloy processing, and at the same time, avoid the exposure of operators to flying alloy debris when adding raw materials, greatly enhancing the safety of operations.

[0005] In order to solve the above technical problems, the utility model provides a protective device for nitriding alloy production, including a feed pipe and a protective mechanism arranged at the upper end of the feed pipe, the protective mechanism including a rotating rod connected to the left and right sides of the upper end of the feed pipe in a transversely symmetrical manner, the outer arc surface of the rotating rod is provided with a sealing plate, the inner end heads of the two sealing plates are arranged in cooperation with each other, and the upper end of the front surface of the feed pipe is also provided with a driving component for driving the rotating rod to rotate.

[0006] The protection mechanism also includes v-shaped grooves respectively arranged at the middle edge of the sealing plate, and sealing strips are arranged in the v-shaped grooves. The inner ends of the two sealing strips are arranged to cooperate with each other, and the front and rear ends of the sealing strips are respectively arranged to cooperate with the corresponding wall surfaces of the feed pipe; the sealing strips are rubber sealing strips.

[0007] The driving assembly includes worm wheels respectively arranged at the front extending ends of the rotating rod, and fixed blocks symmetrically distributed laterally are provided on the left and right sides of the upper end of the front surface of the feed pipe, and a rotating rod is rotatably connected between the two fixed blocks. Worm sleeves symmetrically distributed laterally are provided at the left and right ends of the outer arc surface of the rotating rod, and the worm teeth of the two worm sleeves are in opposite directions. The worm sleeves are respectively meshed with the adjacent worm wheels on the same side, and a driving module for driving the rotating rod to rotate is also provided at the middle of the upper end of the front surface of the feed pipe; the driving module includes a bevel gear ring 2 arranged on the left side of the outer arc surface of the rotating rod, a mounting seat is provided at the middle of the upper end of the front surface of the feed pipe, and an operating rod is rotatably connected to the front surface of the mounting seat, and a bevel gear ring 1 is provided at the rear end of the outer arc surface of the operating rod, and the bevel gear ring 1 is meshed with the bevel gear ring 2.

[0009] The left and right surfaces of the feed pipe are both provided with accommodating grooves corresponding to the sealing plates one by one.

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

[0011] 1. When the nitriding alloy raw materials are not added, the inner sides of the two sealing plates are closely connected, and the elastic pressure is applied to the front and rear walls of the feed pipe through the sealing strip to ensure the tightness of the seal, effectively prevent the leakage of dust-containing gas that may be generated in the production of nitriding alloys, avoid the flying alloy debris from escaping from the feed pipe, and ensure the safety of nitriding alloy processing.

[0012] 2. When it is necessary to add nitride alloy raw materials to the feed pipe, first connect the external feeding pipe with the feed pipe, and then the operator rotates the bevel gear ring 1 through the operating lever. When the bevel gear ring 1 rotates, it drives the rotating rod and the worm sleeve to rotate synchronously through the bevel gear ring 2 meshing with it. Since the worm teeth on the worm sleeve rotate in opposite directions, when the worm sleeve rotates, it drives the rotating rod and the sealing plate to rotate synchronously in the opposite direction through the worm gear, thereby opening the sealing plate and exposing the feed port. At this time, the operator can safely add the required raw materials through the open feed port, which can avoid the operator being exposed to flying alloy debris when adding raw materials, greatly enhancing the safety of the operation.

Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present utility model.

[0019] As Figure 1-4 shown:

[0020] This embodiment provides a protection device for the production of nitrided alloy, including a feed pipe 100 and a protection mechanism arranged at the upper end of the feed pipe 100. The protection mechanism includes rotating rods 200 symmetrically and horizontally rotatably connected to the left and right sides of the upper ends of the front and rear sides of the feed pipe 100. Sealing plates 201 are arranged on the outer arc surfaces of the rotating rods 200. The inner ends of the two sealing plates 201 are arranged in cooperation with each other. A driving assembly for driving the rotation of the rotating rod 200 is also arranged at the upper end of the front surface of the feed pipe 100; the protection mechanism also includes U-shaped grooves respectively arranged at the middle edges of the sealing plates 201. Sealing strips 202 are arranged in the U-shaped grooves. The inner ends of the two sealing strips 202 are arranged in cooperation with each other. The front and rear ends of the sealing strip 202 are respectively arranged in cooperation with the corresponding wall surfaces of the feed pipe 100; the sealing strip 202 is a rubber sealing strip.

[0021] As Figure 1-4As shown, the driving assembly includes a worm gear 300 respectively arranged at the front extension end of the rotating rod 200, a fixed block 301 with laterally symmetrical distribution is provided on the left and right sides of the upper end of the front surface of the feed pipe 100, a rotating rod 302 is rotatably connected between the two fixed blocks 301, and a worm sleeve 303 with laterally symmetrical distribution is provided on the left and right ends of the outer arc surface of the rotating rod 302, the worm teeth of the two worm sleeves 303 are in opposite directions, and the worm sleeves 303 are respectively meshed and connected with the adjacent worm gear 300 on the same side, and a driving module for driving the rotating rod 302 to rotate is also provided at the middle of the upper end of the front surface of the feed pipe 100; the driving module includes a bevel gear ring 2 400 arranged on the left side of the outer arc surface of the rotating rod 302, a mounting seat 401 is provided at the middle of the upper end of the front surface of the feed pipe 100, the front surface of the mounting seat 401 is rotatably connected with an operating rod 402, and a bevel gear ring 1 403 is provided at the rear end of the outer arc surface of the operating rod 402, and the bevel gear ring 1 403 is meshed and connected with the bevel gear ring 2 400.

[0022] like Figure 3 As shown, both left and right surfaces of the feed pipe 100 are provided with receiving grooves 600 corresponding to the sealing plates 201 one by one.

[0023] The working principle of the protective device for nitriding alloy production provided by the utility model is as follows: when the nitriding alloy raw material is not added, the inner side surfaces of the two sealing plates 202 are closely connected, and the sealing strip 202 applies elastic pressure to the front and rear walls of the feed pipe 100, thereby ensuring the tightness of the seal, effectively preventing the leakage of dust-containing gas that may be generated in the production of the nitriding alloy, and avoiding the escape of splashed alloy debris from the pipe opening. When it is necessary to add the nitriding alloy raw material to the feed pipe 100, first connect the external feeding pipe with the feed pipe 100, and then the operator rotates the bevel gear ring 1 403 through the operating rod 402, and the bevel gear ring 1 403 passes through the rotation. The bevel gear ring 2400 meshing with the rotating rod 302 and the worm sleeve 303 are driven to rotate synchronously. Since the worm teeth on the worm sleeve 303 rotate in opposite directions, the worm sleeve 303 drives the rotating rod 200 and the sealing plate 201 to rotate synchronously in the opposite direction through the worm wheel 300 when rotating, thereby opening the sealing plate 201 to expose the feed port. At this time, the operator can safely add the required raw materials through the open feed port, which can avoid the operator being exposed to flying alloy debris when adding raw materials, greatly enhancing the safety of the operation. After adding, the operating lever can be operated in reverse, and the accommodating groove 600 provides a placement place for the opened sealing plate 201.

[0024] like Figure 1As shown, a protective cover 500 is provided at the upper end of the front surface of the feed pipe 100, and a through hole compatible with the operating rod 402 is provided in the middle of the lower end of the front surface of the protective cover 500. The worm gear 300, the fixed block 301, the rotating rod 302, the worm sleeve 303, the bevel gear ring 2 400, the mounting seat 401 and the bevel gear ring 1 403 are all located in the protective cover 500. The protective cover 500 is used to prevent foreign objects from entering and accidental touch by people, thereby improving safety, and also protects the internal mechanical structure from the influence of the external environment.
