Description

Technical Field

[0001] The present invention relates to the technical field of tailings processing, and specifically relates to a screening device for tailings sand aggregate in concrete preparation. Background Technique

[0002] In the existing concrete preparation process, tailings sand, as one of the important sources of aggregate, has gradually received wide attention in the industry. The reuse of tailings sand not only helps to reduce the cost of aggregate, but also has positive significance for resource recycling and ecological protection. However, there are still the following technical problems in the current screening devices for tailings sand aggregate: Firstly, the screening structure is generally relatively single, lacking effective grading and vibrating auxiliary mechanisms, resulting in low screening efficiency of aggregates with different particle sizes. Especially when the tailings sand particles are irregular and the impurity content is large, the sieve mesh is extremely easy to be blocked; Secondly, some devices only rely on one-way vibration or simple screening actions for screening, and it is difficult to form a stable and effective vibration path, resulting in poor screening quality; Thirdly, the existing devices lack the function of adjusting the aggregate distribution during the screening process, resulting in insufficient utilization rate of some sieve surfaces and affecting the processing capacity.

[0003] In addition, regarding the problem of uniform spreading of aggregates during screening, the prior art usually relies on manual pretreatment or simple pouring devices for spreading, which not only has a large labor intensity, but also is difficult to control the uniformity, affecting the screening efficiency and the quality of the final product. Therefore, there is an urgent need to provide a screening device for tailings sand aggregate with a reasonable structure, high screening efficiency, and the ability of automatic distribution adjustment to improve the application effect of tailings sand resources in the concrete preparation process.

[0047] The second screening component 43 includes a driven slider 431, a third limiting rod 432, a fourth limiting rod 433, a second elastic member 434, a support plate 435 and a screening member 436. The driven slider 431 is movably connected to the installation groove 412. One end of the driven slider 431 is fixedly connected to the screening member 436 through the support plate 435. The support plate 435 is connected to the material-carrying member 425. The material-carrying member 425 is arranged below the screening member 436.

The fourth limiting rod 433 is symmetrically arranged with respect to the driven slider 431. The third limiting rod 432 is connected to the fourth limiting rod 433 through the second elastic member 434;

[0048] When the driving slider 421 is started, the driving slider 421 drives the material-carrying member 425 to move. The material-carrying member 425 drives the first limiting rod 422 to move. One side of the first limiting rod 422 approaches the second limiting rod 423, and the first limiting rod 422 on this side presses the first elastic member 424.

[0050] In this embodiment, tailings sand aggregate is fed through the feed inlet 3 provided at the top of the screening box body 1. After the tailings sand aggregate is fed in, it falls onto the screening member 436. At this time, the active slider 421 is started, and the active slider 421 drives the material-carrying member 425 to move. The material-carrying member 425 drives the first limiting rod 422 to move.

The other side of the third limiting rod 432 moves away from the fourth limiting rod 433, and this side of the third limiting rod 432 stretches the second elastic member 434;

[0052] By the movement of the screening member 436, the tailings sand aggregate on the screening member 436 is vibrated, so that the tailings sand aggregate meeting the size requirements falls into the material-carrying member 425 through the holes of the screening member 436. At the same time, when the screening member 436 moves, vibration can be achieved through the buffering of the second elastic member 434, ensuring that the tailings sand aggregate on the screening member 436 does not accumulate.

[0053] In one embodiment, see Figures 1 to 8 , a mixing and stirring mechanism 2 is arranged in the screening box body 1, and the mixing and stirring mechanism 2 is arranged above the screening mechanism 4.

[0054] Furthermore, see Figures 1 to 8 , the mixing and stirring mechanism 2 includes:

[0055] A first installation component 21, the first installation component 21 is installed on the side plate of the screening box body 1, and the first installation component 21 is connected to the guiding component 22;

The direction-changing component 23 is arranged in the installation sleeve 212, and the installation sleeve 212 is movably connected to the guiding component 22.

[0058] Further, referring to Figures 1 to 8 , the guiding assembly 22 includes:

[0059] A first guiding column 221, the first guiding column 221 is fixedly connected to the first mounting member 211, and a redirecting assembly 2 is provided on the first guiding column 221;

[0061] A third guiding column 223, the third guiding column 223 is fixedly connected to the first mounting member 211, and a redirecting assembly 2 is provided on the third guiding column 223.

[0062] Further, referring to Figures 1 to 8 , the redirecting assembly 23 includes:

[0063] A first sleeve 231, the first sleeve 231 is movably connected to the first guiding column 221, and the first sleeve 231 is fixedly connected to the mounting sleeve 212;

[0064] A first guiding thread 232, the first guiding thread 232 is provided on the outer side of the second guiding column 222, the first guiding thread 232 is threadedly connected to a threaded sleeve 233, and the threaded sleeve 233 is fixedly connected to the mounting sleeve 212;

[0066] In this embodiment, both the second guiding column 222 and the third guiding column 223 are power components. When the second guiding column 222 is started, the second guiding column 222 drives the first guiding thread 232 to rotate, and the first guiding thread 232 drives the threaded sleeve 233 to move. Since the threaded sleeve 233 is internally provided with threads and the threaded sleeve 233 is arranged in the mounting sleeve 212, the threaded sleeve 233 can push the mounting sleeve 212 to move. At this time, the mounting sleeve 212 drives the mixing stirring plate 24 to perform a horizontal movement. Through the horizontal movement of the mixing stirring plate 24, the tailings sand aggregate located on the screening member 436 is spread out, improving the working efficiency of the screening member 436;

[0067] When starting the third guiding column 223, the third guiding column 223 drives the second guiding thread 235 to rotate through the second sleeve 234. The second guiding thread 235 drives the connecting gear 236 to rotate, and the connecting gear 236 drives the mixing stirring plate 24 to rotate. At this time, the mixing stirring plate 24 spreads the tailings sand aggregate located on the screening member 436.

[0068] When starting the second guiding column 222 and the third guiding column 223 simultaneously, when the mixing stirring plate 24 moves back and forth, it can rotate simultaneously. At the same time, through the first sleeve 231 on the first guiding column 221, the movement track of the mounting sleeve 212 is ensured.

[0069] The working principle of the present invention is:

[0070] Through the movement of the screening member 436, the tailings sand aggregate on the screening member 436 is vibrated, so that the tailings sand aggregate meeting the size falls into the material receiving member 425 through the holes of the screening member 436. At the same time, when the screening member 436 moves, vibration can be achieved through the buffering of the second elastic member 434, ensuring that the tailings sand aggregate on the screening member 436 does not accumulate.

[0071] When starting the second guiding column 222 and the third guiding column 223 simultaneously, when the mixing stirring plate 24 moves back and forth, it can rotate simultaneously. At the same time, through the first sleeve 231 on the first guiding column 221, the movement track of the mounting sleeve 212 is ensured.

[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
