At the same time, the sliding member 32 can be used to move the clearing member 31 away from the slag discharge port 11, which is conducive to the smooth slag discharge of the slag discharge port 11.

[0052] It should be noted that the slag discharge device and concentrator of the present invention are used for but not limited to the technical field of concentrators. For the convenience of explanation, in the present invention, only the slag discharge device and concentrator are applied to the technical field of concentrators as an example for explanation. The principles of the slag discharge device and concentrator applied to other types of equipment are essentially the same as those applied to the technical field of concentrators, and will not be described one by one here.

[0053] See also Figures 1 to 4 , Figure 1 This is a structural schematic diagram of a slag discharge device and a concentrator in one embodiment of the present invention. The slag discharge device is connected to the concentrator body 1. A slag discharge port 11 is provided at the bottom of the concentrator body 1. The slag discharge device includes: a bracket 2 and a dredging assembly 3. The bracket 2 is used to connect to the concentrator body 1. The dredging assembly 3 includes a dredging piece 31, a sliding piece 32 and a lifting piece 33. The dredging piece 31 is arranged relative to the slag discharge port 11 and can rotate relative to the bracket 2. The sliding piece 32 is connected to the dredging piece 31 and is slidably connected to the bracket 2, and is used to drive the dredging piece 31 to move horizontally relative to the bracket 2 and the slag discharge port 11. The lifting piece 33 has a fixed end and a movable end. The fixed end of the lifting piece 33 is connected to the sliding piece 32, and the movable end is connected to the dredging piece 31, and is used to drive the dredging piece 31 to move closer to or away from the bracket 2 and the slag discharge port 11.

[0054] In this device, the bracket 2 is used to connect with the concentrator body 1, and the clearing piece 31 is connected to the bracket 2 via the sliding piece 32 and the lifting piece 33.

[0055] Compared with the prior art, a clearing piece 31 is provided relative to the slag discharge port 11, and a sliding piece 32 and a lifting piece 33 are used to drive the clearing piece 31 to move horizontally or vertically relative to the slag discharge port 11, so that the clearing piece 31 can be repeatedly inserted into or pulled out of the slag discharge port 11, so as to clear the impurities blocking the slag discharge port 11. At the same time, the sliding piece 32 can be used to move the clearing piece 31 relative to the slag discharge port 11, which is conducive to the smooth discharge of slag from the slag discharge port 11. It can solve the technical problem in the prior art that impurities are easily accumulated at the bottom of the inner cavity of the concentrator, causing blockage of the slag discharge port 11 during material discharge, requiring manual assistance to clean the impurities in the slag discharge port 11, thereby causing inconvenience in use.

[0056] Specifically, a filtering component and a feeding component are provided in the concentrator body 1. Reference can be made to the Chinese invention patent application number: CN202010482775.2, entitled: A concentrator with multi-layer washing function. This is a conventional setting known to those skilled in the art and will not be elaborated on here.

[0057] In this embodiment, Figures 2 to 4 As shown, the sliding member 32 includes a sliding block 321 and a first driving part 322, the first driving part 322 includes a rack 3221, a gear 3222 and a first driving motor 3223, the lifting member 33 includes a lifting seat 331 and a second driving part 332, a limit block 333, the second driving part 332 includes a screw 3321, a guide rod 3322 and a second driving motor 3323, the clearing member 31 includes a rotating shaft 311, a spiral blade 312 and a third driving motor 313, and a sealing sleeve 314.

[0058] Among them, the bracket 2 is provided with a sliding groove along its length direction, one end of the sliding block 321 is slidably connected to the sliding groove, and the other end is connected to the fixed end of the lifting member 33, and the first driving part 322 is connected to the bracket 2 and the sliding block 321, and is used to drive the sliding block 321 to slide along the guide of the sliding groove.

[0059] The sliding block 321 slides in cooperation with the slide groove to support and connect the sliding of the clearing member 31 and the lifting member 33 relative to the bracket 2.

[0060] In one embodiment, see 2 to Figure 4The cross-section of the slide is T-shaped and has a first segment and a second segment. The cross-sectional area of ​​the first segment is larger than that of the second segment, and the second segment is arranged relative to the first segment near the fixed end of the lifting member 33 and passes through the outer wall of the bracket 2. The sliding block 321 is arranged in conjunction with the slide, and the rack 3221 is arranged along the guide of the slide and connected to the inner wall of the first segment. The gear 3222 is rotatably built into the first segment and meshes with the rack 3221. The fixed end of the drive motor is connected to the sliding block 321, and the output shaft is connected to the gear 3222, which is used to drive the gear 3222 to mesh with the rack 3221 and drive the sliding block 321 to slide along the guide of the slide.

[0061] Driven by the output shaft of the first drive motor 3223, the gear 3222 can engage with the rack 3221. The engaged gear 3222 can drive the sliding block 321 to slide relative to the slide groove, thereby making the clearing member 31 and the lifting member 33 move closer to or away from the slag discharge port 11.

[0062] In one embodiment, see Figure 4 The lifting seat 331 is used to connect the clearing piece 31, and the clearing piece 31 can rotate relative to the lifting seat 331. The second driving part 332 has a fixed end and an extension end. The fixed end of the second driving part 332 is connected to the sliding block 321, and the extension end is connected to the lifting seat 331, which is used to drive the clearing piece 31 and the lifting seat 331 close to or away from the sliding block 321.

[0063] The dredging member 31 is connected to the extended end of the second driving part 332 through the lifting seat 331 and can be raised and lowered relative to the bracket 2 and the slag discharge port 11 along with the lifting seat 331.

[0064] As an implementation method, Figure 4 As shown, the lifting seat 331 is provided with a first threaded hole and a guide hole. The guide hole is polygonal and is spaced apart from the first threaded hole. One end of the screw 3321 is threadedly connected to the first threaded hole. The guide rod 3322 passes through the guide hole and is connected to the sliding block 321. The fixed end of the second drive motor 3323 is connected to the sliding block 321, and the output shaft is connected to the screw 3321, which is used to drive the lifting seat 331 to slide along the axis of the screw 3321.

[0065] The screw rod 3321 and the first threaded hole on the lifting seat 331 form a structure similar to a ball screw nut pair, so that the rotation of the screw rod 3321 around its own axis can drive the lifting seat 331 to rotate. At the same time, due to the cooperation between the guide hole and the guide rod 3322, the lifting seat 331 cannot rotate and can only slide along the axis of the screw rod 3321, thereby realizing the lifting movement.

[0066] Furthermore, the cross-section of the guide hole here can be a triangle, a square, a rectangle, a pentagon or a polygon, which will not be described in detail here.

[0067] As an embodiment, the sliding block 321 is provided with a first accommodating cavity and a first rotating hole, the first rotating hole is connected to the first accommodating cavity, the fixed end of the second drive motor 3323 is connected to the inner wall of the first accommodating cavity, the output shaft passes through the first rotating hole, and is connected to the screw 3321.

[0068] The first accommodating chamber is used to accommodate the second driving motor 3323, thereby preventing the second driving motor 3323 from being damaged by leakage and improving the stability of the device operation.

[0069] As a preferred embodiment, Figure 4 As shown, the limiting block 333 is connected to the other end of the guide rod 3322 away from the sliding block 321 .

[0070] The limiting block 333 is used to separate the guide rod 3322 from the guide hole.

[0071] In one embodiment, see Figure 4 The lifting seat 331 is provided with a second accommodating chamber and a second rotating hole. The second rotating hole is connected to the second accommodating chamber. One end of the rotating shaft 311 is inserted into the second rotating hole, and the other end is rotated outside the lifting seat and arranged relative to the slag discharge port 11. The spiral blade 312 is fixedly sleeved on the circumferential outer wall of the rotating shaft 311. The fixed end of the third drive motor 313 is connected to the inner wall of the second accommodating chamber, and the output shaft is connected to one end of the rotating shaft 311.

[0072] The spiral blade 312 is connected to the output shaft of the third drive motor 313 via the rotating shaft 311 to achieve rotation relative to the lifting seat 331 , which is beneficial for clearing the slag discharge port 11 .

[0073] Furthermore, the second accommodating chamber is used to accommodate the third drive motor 313, thereby preventing the third drive motor 313 from being damaged by leakage and improving the stability of the device operation.

[0074] In one embodiment, see Figures 2 to 4 The sealing sleeve 314 is sleeved on the rotating shaft 311 and connected to the second rotating hole, and the rotating shaft 311 can rotate relative to the sealing sleeve 314.

[0075] The sealing sleeve 314 is provided to improve the sealing and waterproof performance of the third driving motor 313 and enhance the stability of the device operation.

[0076] Furthermore, the first drive motor 3223, the second drive motor 3323 and the third drive motor 313 in this device are all forward and reverse motors that are common and easy to purchase on the market. This is a conventional setting known to those skilled in the art and will not be described in detail here.

[0077] In this embodiment, Figure 1 As shown, the utility model also provides a concentrator, including a concentrator body 1, a slag discharge device, and an auxiliary device 4, the auxiliary device 4 includes an air inlet pipe 41 and an air compressor 42, one end of the air inlet pipe 41 is connected to the interior of the concentrator body 1, and the air outlet end of the air compressor 42 is connected to the other end of the air inlet pipe 41.

[0078] In this device, according to the pressure of the concentrating chamber of the concentrator (determined by the amount of material, which will not be described here), the air compressor 42 supplies compressed air into the concentrating chamber, the pressure in the concentrating chamber increases, the slurry is extracted through the filter rod and the pump, and the clear liquid flows out from the top. At the same time, the impurities generated in the process are discharged from the slag discharge port 11.

[0079] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail:

[0080] The bracket 2 is used to connect with the concentrator body 1, and the clearing piece 31 is connected to the bracket 2 via the sliding piece 32 and the lifting piece 33. The clearing piece 31 is arranged relative to the slag discharge port 11 and can rotate relative to the bracket 2. The sliding piece 32 can drive the clearing piece 31 to move horizontally relative to the bracket 2, so that the clearing piece 31 moves horizontally close to or away from the slag discharge port 11. The lifting piece 33 can drive the clearing piece 31 to move closer to or away from the bracket 2 and make the clearing piece 31 inserted into or pulled out of the slag discharge port 11 to clear the blockage in the slag discharge port 11. Compared with the existing technology, a clearing piece 31 is set relative to the slag discharge port 11, and the sliding piece 32 and the lifting piece 33 are used to drive the clearing piece 31 to move horizontally or lift relative to the slag discharge port 11, so that the clearing piece 31 can be repeatedly inserted into or pulled out of the slag discharge port 11, so as to clear the impurities blocking the slag discharge port 11. At the same time, the sliding piece 32 can be used to move the clearing piece 31 relative to the slag discharge port 11, which is conducive to the smooth slag discharge of the slag discharge port 11.

[0081] The specific working process of the present invention is as follows: when in use, according to the pressure of the concentrating chamber of the concentrator (determined by the amount of material, which will not be described in detail here), the air compressor 42 supplies compressed air into the concentrating chamber, the pressure in the concentrating chamber increases, the slurry is extracted through the filter rod and the pump, and the clear liquid flows out from the top. At the same time, the impurities generated in the process are discharged from the slag discharge port 11.

[0082] Furthermore, the first drive motor 3223, the second drive motor 3323 and the third drive motor 313 respectively drive the spiral blade 312 and the rotating shaft 311 to insert into the slag discharge port 11. Through the forward and reverse rotation of the second drive motor 3323, the spiral blade 312 and the rotating shaft 311 can be repeatedly inserted into or pulled out of the slag discharge port 11, which is beneficial to the unblocking of the slag discharge port 11. When the unblocking is completed, the second drive motor 3323 first drives the spiral blade 312 and the rotating shaft 311 to be pulled out from the slag discharge port 11, and then the first drive motor 3223 drives the sliding block 321, the spiral blade 312 and the rotating shaft 311 to move horizontally away from the slag discharge port 11, which is beneficial to the discharge of impurities from the slag discharge port 11. The structure is simple and the operation is convenient.

[0083] The above structure of the device can solve the technical problem in the prior art that impurities easily accumulate at the bottom of the inner cavity of the concentrator, causing blockage of the slag discharge port 11 during material discharge and requiring manual assistance to clean the impurities in the slag discharge port 11, thereby causing inconvenience in use.

[0084] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
