Description

Technical Field

[0001] The utility model relates to the technical field of slag processing, in particular to a slag fragment screening machine. Background Technique

[0002] The main uses of slag powder are to be mixed in cement and added to commercial concrete. Their utilization methods are different. Generally speaking, they are mainly manifested in three utilization forms: admixture form, blending material form, and main admixture form. The main functions are to improve the early strength of cement and concrete and to improve some properties of concrete (such as workability, increase early strength, reduce heat of hydration, etc.).

[0003] Before the slag is made into slag powder, it needs to be first crushed into fragments and then ground into fine powder. However, there is still a part of the slag fragments that are not completely crushed mixed in. If they are not picked out, it will affect the subsequent grinding efficiency. Therefore, it is necessary to separate them and crush the fragments again. When the existing slag fragment screening machine separates the slag fragments, it usually directly puts the fragments into the screen for screening. The qualified fragments will pass through the screen, while the unqualified fragments will remain in the screen and need to be removed to discharge the materials, which is rather troublesome to operate, thus affecting the screening efficiency of the fragments.

[0004] Therefore, a slag fragment screening machine is proposed to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a slag fragment screening machine, which has the advantages of high screening efficiency and solves the problem that when the existing slag fragment screening machine separates the slag fragments, it usually directly puts the fragments into the screen for screening and the screening is not thorough enough.

[0006] To achieve the above object, the utility model provides the following technical solution: A slag fragment screening machine, including a frame, on which a separation mechanism and a driving mechanism are provided;

[0007] The separation mechanism includes a separation bin, in which a separation screen is fixed. At the bottom opening of the separation bin, two slag collection hoppers are also fixed. There is a slag fragment channel on the side of the separation bin that communicates with the space above the separation screen. A blocking structure is provided in the separation bin to block the slag fragments from falling into the slag fragment channel;

[0008] The driving mechanism includes a pair of rotating long arms and a pair of rotating short arms rotatably arranged on the frame. A connecting rod is hinged between the rotating long arm and the rotating short arm on the same side. Link plates are fixed on the sides of the rotating long arm and the rotating short arm close to the separation bin. One end of the link plate is hinged to the separation bin by a short rod, and the other end of the link plate is hinged to the slag collection hopper by a long rod.

[0009] Furthermore, the blocking structure includes a mounting beam fixed to the separation bin. A mounting sleeve is fixed on the side of the mounting beam. There is a mounting rod in the mounting sleeve. The mounting rod is restricted in the mounting sleeve by a nut. A baffle is fixed to the bottom of the mounting rod.

[0010] Furthermore, a driving shaft is rotatably arranged on the frame through a bearing. Rotating discs are fixed at both ends of the driving shaft. The eccentric part of the rotating disc is rotatably connected to a driving rod through a rotating shaft. The end of the driving rod is hinged to the rotating long arm.

[0011] Furthermore, a driving motor is fixed on the frame. A transmission shaft is rotatably arranged on the frame through a bearing. The output shaft of the driving motor and the transmission shaft, as well as the transmission shaft and the driving shaft, are respectively driven by a belt drive structure.

[0012] Furthermore, a fixed frame is fixed on the outside of the separation bin. The short rod is hinged between one end of the link plate and the fixed frame. A connecting frame is fixed on the outside of the slag collection hopper. The long rod is hinged between the other end of the link plate and the connecting frame.

[0013] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0014] For this slag crushing and screening machine, the slag crushing materials are put into the separation bin through the top opening of the separation bin. The slag crushing materials of different sizes can be separated through the separation net. The small slag crushing materials pass through the separation net and fall into the slag collection hopper, while the large slag crushing materials are blocked on the separation net. Then, by controlling the blocking structure to no longer block the slag crushing material passage, the slag crushing materials on the separation net can be dialed into the slag crushing material passage for collection. The swinging separation bin can also assist the crushing materials to fall into the slag crushing material passage, which helps to improve the discharge efficiency of unqualified crushing materials.

[0015] The rotating long arm and the rotating short arm can drive the separation bin and the slag collection hopper to swing regularly through the long rod and the short rod, thereby accelerating the sorting efficiency of the slag crushing materials in the separation bin and making the sorting of the slag crushing materials more thorough.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , a slag fragment screening machine in this embodiment includes a frame 1, a separation mechanism 2 and a driving mechanism 3 are provided on the frame 1. The slag fragments are thrown into the separation mechanism 2, and the qualified slag fragments can be separated from the unqualified slag fragments. The driving mechanism 3 can drive the separation mechanism 2 to swing, thereby improving the separation efficiency.

[0024] Since before the slag is made into slag micro-powder, the slag needs to be first crushed into fragments and then ground into fine powder. However, there is still a part of the uncompletely crushed slag fragments mixed in the crushed slag fragments, and they need to be separated and crushed again. The separation mechanism 2 can separate the two, specifically as Figures 2-3As shown, the separation mechanism 2 includes a separation bin 201. A separation screen 202 is fixed inside the separation bin 201. Two slag debris collection hoppers 203 are also fixed at the bottom opening of the separation bin 201. There is a slag debris channel 204 on the side of the separation bin 201 that communicates with the space above the separation screen 202. A blocking structure 205 is provided inside the separation bin 201 to prevent slag debris from falling into the slag debris channel 204.

[0025] The slag debris is put into the separation bin 201 from the top opening of the separation bin 201. The qualified and unqualified slag debris can be separated through the separation screen 202. The qualified slag debris can pass through the separation screen 202 and fall into the slag debris collection hopper 203. The unqualified slag debris is blocked on the separation screen 202. By controlling the blocking structure 205 to no longer block the slag debris channel 204, the slag debris on the separation screen 202 can be pushed into the slag debris channel 204 for collection. The swinging separation bin 201 can also assist the debris to fall into the slag debris channel 204, which helps to improve the discharge efficiency of the unqualified debris.

[0026] As Figure 3 shown, the blocking structure 205 includes a mounting beam 2051 fixed to the separation bin 201. A mounting sleeve 2052 is fixed to the side of the mounting beam 2051. There is a mounting rod 2053 inside the mounting sleeve 2052. The mounting rod 2053 is restricted inside the mounting sleeve 2052 by a nut. A baffle 2054 is fixed to the bottom of the mounting rod 2053. By loosening the nut, the mounting rod 2053 is no longer restricted inside the mounting sleeve 2052, and the baffle 2054 can be raised to no longer block the slag debris channel 204. The slag debris on the separation screen 202 can then be exported from the slag debris channel 204 for collection.

[0027] The driving mechanism 3 can be used to drive the separation mechanism 2 to swing, thereby accelerating the separation efficiency. Specifically, as Figures 4-5As shown in the figure, the driving mechanism 3 includes a driving motor 301 fixed to the frame 1. A transmission shaft 302 and a driving shaft 303 are rotatably provided on the frame 1 through bearings. The output shaft of the driving motor 301 and the transmission shaft 302, as well as between the transmission shaft 302 and the driving shaft 303, are respectively driven by a belt transmission structure 304. Rotating disks 305 are fixed at both ends of the driving shaft 303. An eccentric part of the rotating disk 305 is rotatably connected to a driving rod 306 through a rotating shaft. A pair of rotating long arms 307 and a pair of rotating short arms 308 are rotatably provided on the frame 1 through rotating shafts. The end of the driving rod 306 is hinged to the rotating long arm 307. A connecting rod 309 is hinged between the rotating long arm 307 and the rotating short arm 308 on the same side. Link plates 310 are fixed on the sides of the rotating long arm 307 and the rotating short arm 308 close to the separation bin 201. A fixed frame 311 is fixed on the outside of the separation bin 201. A short rod 312 is hinged between one end of the link plate 310 and the fixed frame 311. A connecting frame 313 is fixed on the outside of the slag collection hopper 203. A long rod 314 is hinged between the other end of the link plate 310 and the connecting frame 313.

[0028] The output shaft of the driving motor 301 drives the transmission shaft 302 to rotate through the belt transmission structure 304. Also, under the driving action of the corresponding belt transmission structure 304, the driving shaft 303 rotates. After the rotating disk 305 rotates, under the driving action of the driving rod 306 and the linkage action of the connecting rod 309, the rotating long arm 307 and the rotating short arm 308 can drive the separation bin 201 and the slag collection hopper 203 to swing through the long rod 314 and the short rod 312, thereby accelerating the sorting efficiency of the slag fragments in the separation bin 201.

[0029] By adopting the above slag fragment screening machine, slag can be quickly separated from the mine. The specific separation method is as follows:

[0030] The slag fragments are put into the separation bin 201 from the top opening of the separation bin 201. The qualified slag fragments and the unqualified slag fragments can be separated through the separation net 202. The qualified slag fragments can pass through the separation net 202 and fall into the slag collection hopper 203. The unqualified slag fragments are blocked on the separation net 202. Then, by controlling the blocking structure 205 to no longer block the slag fragment passage 204, the slag fragments on the separation net 202 can be dialed into the slag fragment passage 204 and collected through the slag fragment passage 204.

[0031] The control mode of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present invention mainly aims to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.
