Description

Technical Field

[0001] The utility model relates to the technical field of thickener feeding, in particular to a feeding device for a central hydraulic drive thickener. Background Art

[0002] Concentration is a common operation in the ore dressing production process. Conventional thickening equipment at home and abroad is mainly a thickener. Its basic principle is to precipitate from the pulp by the gravity of the ore itself to achieve the purpose of de-sludging or dewatering. At present, when a conventional thickener is working, the pulp enters the thickening tank through the feed pipe and directly diffuses around. During this process, the pulp gradually sinks to the inclined bottom of the thickening tank by its own gravity.

[0003] The existing thickener has the following problems when working. The pulp directly enters the receiving barrel from the feed pipe, and the incoming material speed is fast and the kinetic energy is large, which destroys the original balance and internal stratification of the thickening tank, causing some precipitated particles to be impacted and become disordered, affecting the thickening progress. However, only using the gravity of the pulp to feed, the feeding speed is very slow, thus affecting the thickening progress, and the overall precipitation speed is slow. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a feeding device for a central hydraulic drive thickener, which has the advantage of fully mixing the flocculant and the pulp to accelerate the flocculation precipitation speed, and avoids the problem of slow precipitation speed.

[0005] To achieve the purpose of fully mixing the flocculant and the pulp to accelerate the flocculation precipitation speed, the utility model provides the following technical solutions:

Detailed implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1-3 , a fabric feeding device for a central hydraulic drive thickener, including a barrel body 1, a fabric barrel 101 is fixedly connected to the inner top wall of the barrel body 1, and the bottom side walls of the barrel body 1 and the fabric barrel 101 are both inclined. A mounting frame 102 is fixedly connected to the top of the barrel body 1, and further includes:

[0023] A servo motor 2 is fixedly connected to the top of the mounting frame 102, the output end of the servo motor 2 is fixedly connected to a rotating shaft 201, and the rotating shaft 201 penetrates through the fabric barrel 101 and extends to the bottom inner wall of the barrel body 1. A stirring plate 202 is fixedly connected to the side wall of the rotating shaft 201 inside the fabric barrel 101. A backflow port is opened at the bottom side wall of the fabric barrel 101. A liquid storage tank 203 is fixedly connected to the top of the barrel body 1. A first sliding plate 204 is slidably connected to the inner wall of the liquid storage tank 203, and a first spring 205 is fixedly connected between the first sliding plate 204 and the liquid storage tank 203;

[0024] A first connecting column 206 is fixedly connected to the side wall of the first sliding plate 204, and a first collision plate 207 is fixedly connected to the side wall of the first connecting column 206 outside the liquid storage tank 203;

[0025] An extrusion column 208 is fixedly connected to the side wall of the rotating shaft 201 outside the barrel body 1, and the extrusion column 208 can be attached to the first collision plate 207. A feed pipe 209 is fixedly connected to the side wall of the fabric barrel 101. A first connecting pipe 210 is fixedly connected between the liquid storage tank 203 and the fabric barrel 101;

[0026] It should be noted that the pulp is introduced into the inner cavity of the cloth bucket 101 through the feed pipe 209. Subsequently, the servo motor 2 at the top of the mounting frame 102 is driven, and the servo motor 2 drives the rotating shaft 201 and the stirring plate 202 on its side wall to rotate. During this process, the pulp is stirred by the stirring plate 202. Since the bottom side wall of the cloth bucket 101 is set to be arc-shaped, the pulp in the inner cavity of the cloth bucket 101 will spread from the diversion port to the inner cavity of the barrel 1. When the rotating shaft 201 rotates, it will drive the extrusion column 208 to rotate. When the extrusion column 208 rotates, it collides with the first collision plate 207, causing the first collision plate 207 to drive the first sliding plate 204 to slide towards the inner wall of the liquid storage tank 203 through the first connecting column 206. The first spring 205 is compressed to generate a rebound force, and at the same time, the pressure in the inner cavity of the liquid storage tank 203 increases. As a result, the flocculant in the inner cavity of the liquid storage tank 203 flows into the inner cavity of the cloth bucket 101 through the first connecting pipe 210 and is fully mixed with the pulp, facilitating the subsequent flocculation precipitation of the pulp in the inner cavity of the barrel 1. After the extrusion column 208 moves away from the first collision plate 207, under the elastic force of the first spring 205, the first collision plate 207 and the like will return to their original positions, waiting for the next collision, so that the flocculant can be continuously added into the inner cavity of the cloth bucket 101.

[0027] Refer to Figures 1-3 , a cleaning block 3 is fixedly connected to the end of the stirring plate 202, and the cleaning block 3 is in contact with the inner wall of the cloth bucket 101;

[0028] On both side walls of the rotating shaft 201 at the bottom of the inner cavity of the barrel 1, sleeve plates 301 are fixedly connected. A scraping plate 302 is slidably connected in the inner cavity of the sleeve plate 301, and a second spring 303 is fixedly connected between the scraping plate 302 and the sleeve plate 301;

[0029] It should be noted that under the elastic force of the second spring 303, the scraping plate 302 has a tendency to slide towards the outside of the sleeve plate 301, so that the scraping plate 302 is in contact with the inner wall of the barrel 1. Therefore, when the rotating shaft 201 rotates, it will drive the sleeve plate 301 and its scraping plate 302 to rotate, thereby cleaning the sediment adhering to the inner wall of the barrel 1. Similarly, the rotating shaft 201 drives the cleaning block 3 to clean the inner cavity of the cloth bucket 101.

[0030] Refer to Figures 1-3 , a pressurizing box 304 is fixedly connected to the top of the barrel 1. A second connecting pipe 305 is fixedly connected between the pressurizing box 304 and the feed pipe 209, and one-way valves are provided on the side walls of the pressurizing box 304, the top of the liquid storage tank 203, the first connecting pipe 210, and the second connecting pipe 305;

[0031] A second sliding plate 306 is slidably connected to the inner wall of the pressurizing box 304, and a third spring 307 is fixedly connected between the second sliding plate 306 and the pressurizing box 304;

[0032] A second connecting column 308 is fixedly connected to the side wall of the second sliding plate 306, and a second collision plate 309 is fixedly connected to the end of the second connecting column 308 located outside the pressure box 304;

[0033] It should be noted that: Similarly, when the rotating shaft 201 drives the extrusion column 208 to collide with the second collision plate 309, the second sliding plate 306 slides to increase the pressure inside the pressure box 304. Then, the gas inside the pressure box 304 leads to the inside of the feed pipe 209, accelerating the feeding speed of the feed pipe 209. Moreover, the elastic force of the third spring 307 enables the pressure box 304 to repeatedly pressurize the feed pipe 209.

[0034] Operation method: Feed the pulp into the inner cavity of the cloth bucket 101 through the feed pipe 209, and then drive the servo motor 2 at the top of the mounting frame 102. The servo motor 2 drives the rotating shaft 201 and the stirring plate 202 on its side wall to rotate. During this process, the pulp is stirred by the stirring plate 202. Since the bottom side wall of the cloth bucket 101 is set to be arc-shaped, the pulp inside the cloth bucket 101 will spread from the diversion port to the inside of the barrel 1. When the rotating shaft 201 rotates, it will drive the extrusion column 208 to rotate. When the extrusion column 208 rotates, it collides with the first collision plate 207, causing the first collision plate 207 to drive the first sliding plate 204 to slide towards the inner wall of the liquid storage tank 203 through the first connecting column 206. The first spring 205 is compressed to generate a rebound force, and at the same time, the pressure inside the liquid storage tank 203 increases. Then, the flocculant inside the liquid storage tank 203 flows into the inner cavity of the cloth bucket 101 through the first connecting pipe 210 and is fully mixed with the pulp, facilitating the subsequent flocculation precipitation of the pulp inside the barrel 1. After the extrusion column 208 moves away from the first collision plate 207, under the elastic force of the first spring 205, the first collision plate 207 and the like will return to their original positions, waiting for the next collision, so that the flocculant can be continuously added into the inner cavity of the cloth bucket 101;

[0035] Similarly, when the rotating shaft 201 drives the extrusion column 208 to collide with the second collision plate 309, the second sliding plate 306 slides to increase the pressure inside the pressure box 304. Then, the gas inside the pressure box 304 leads to the inside of the feed pipe 209, accelerating the feeding speed of the feed pipe 209. Moreover, the elastic force of the third spring 307 enables the pressure box 304 to repeatedly pressurize the feed pipe 209. Among them, under the elastic force of the second spring 303, the scraping plate 302 has a tendency to slide towards the outside of the sleeve plate 301, so that the scraping plate 302 fits with the inner wall of the barrel 1. Therefore, when the rotating shaft 201 rotates, it will drive the sleeve plate 301 and its scraping plate 302 to rotate, thereby cleaning the sediment adhering to the inner wall of the barrel 1. Similarly, the rotating shaft 201 drives the cleaning block 3 to clean the inner cavity of the cloth bucket 101.
