Description

Technical Field

[0001] This utility model relates to the technical field of coarse coal slime recovery and clean coal recovery devices, and in particular to a coarse coal slime recovery and clean coal recovery device. Background Technology

[0002] Existing technologies, such as CN222358811U, describe a coal preparation plant's coal slurry and clean coal recovery equipment. This equipment reduces the impurity content in coarse coal slurry by blowing off dust from the raw materials in advance and classifying coal slag by size, thereby improving the quality of clean coal extraction. However, during the free fall of the raw materials, if the airflow is strong, small pieces of coal slag are easily blown off along with them; if the airflow is weak, the ash removal effect is poor. Furthermore, the fixed mesh filter chamber for screening has low practicality. Utility Model Content

[0003] Therefore, it is necessary to provide a device for recovering clean coal from coarse coal slime, addressing the aforementioned technical problems of poor soot blowing effect and low practicality.

[0004] To achieve the above objectives, this utility model provides a coarse coal slime recovery and fine coal recovery device, including a frame, a blower mechanism, and a drive mechanism. An arc-shaped receiving plate is installed inside the frame, and the arc-shaped receiving plate has several cleaning holes. An arc-shaped guide plate is installed on the arc-shaped receiving plate, and the top of the arc-shaped guide plate is located below the feed inlet of the frame. A vibrating table is slidably engaged on the frame. A filter chamber, an adjusting filter plate, a first collection chamber, and a second collection chamber are slidably engaged on the vibrating table from top to bottom. The filter chamber and the adjusting filter plate are configured to cooperate. A rotating frame is hinged to the adjusting filter plate. An elastic component is installed inside the adjusting filter plate. The output end of the elastic component is connected to the rotating frame. The rotating frame is configured to cooperate with the first collection chamber.

[0005] Preferably, a friction block is slidably mounted on the frame, and a brake block is mounted on the adjusting filter plate, with the friction block and the brake block abutting against each other.

[0006] Preferably, the brake block is provided with a groove.

[0007] Preferably, a guide frame is installed on the frame, and the friction block is slidably engaged in the guide frame.

[0008] Preferably, an elastic component two is installed inside the guide frame, and the output end of the elastic component two is connected to the friction block.

[0009] Preferably, an extension plate is installed below the arc-shaped receiving plate.

[0010] Compared with existing technologies, this technical solution has at least one of the following beneficial effects: 1. By combining the arc-shaped receiving plate and the arc-shaped guide plate, the material can roll along the arc-shaped guide plate after falling. The arc shape of the receiving plate can also deflect the material to a certain extent, thus improving the dust removal effect. 2. By adjusting the filter plate settings, the size of the material blocks filtered in the filter chamber can be adjusted. Furthermore, due to the rotating frame, when the first collection chamber has finished collecting and is being removed, the filter plate can be moved by the rotating frame to automatically adjust the mesh size, so that the second collection box can collect larger pieces of material.

[0012] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] Please see Figures 1 to 3This application provides a device for recovering clean coal from coarse coal slime, including a frame 1, a blower mechanism, and a drive mechanism. The blower mechanism is a blower, fan, or other equipment in the prior art, with a dust collection box installed opposite it. The drive mechanism can drive a vibrating table 4 to vibrate up and down. It can be a vibrating motor or a motor driving a crank-connecting rod mechanism to move it up and down. A shock-absorbing spring or damping spring can be installed at the bottom of the vibrating table 4 to cooperate in vibration. An arc-shaped receiving plate 2 is fixedly installed inside the frame 1. The arc-shaped receiving plate 2 has several dust removal holes. An arc-shaped guide plate 3 is fixedly installed on the arc-shaped receiving plate 2. The top of plate 3 is located below the feed inlet of frame 1; a vibrating table 4 is slidably connected to frame 1, and a filter chamber 5, an adjusting filter plate 6, a collection chamber 1 7 and a collection chamber 2 8 are slidably connected to the vibrating table 4 from top to bottom. The filter chamber 5 and the adjusting filter plate 6 are configured to cooperate. A rotating frame 9 is hinged to the adjusting filter plate 6. An elastic component, which is a spring, is fixedly installed inside the adjusting filter plate 6. The output end of the elastic component is connected to the rotating frame 9. The rotating frame 9 has an F-shaped cross section. A rotating shaft is rotatably installed on the adjusting filter plate 6 for hinged connection with the rotating frame 9. The elastic component is installed on the rotating shaft. The rotating frame 9 is configured to cooperate with the collection chamber 1 7.

[0014] In this embodiment, after the material is fed into the top feed port of the frame 1, it falls above the uppermost arc-shaped guide plate 3 and rolls along the arc-shaped receiving plate 2 under its guidance. This reduces the falling speed of the material, making it easier for the blower mechanism to clean it. The arc shape of the receiving plate 2 allows the material block to deflect at a certain angle relative to the direction of the airflow from the blower mechanism when it rolls, thereby further improving the cleaning effect. The cleaning holes are small, allowing only dust to pass through without causing material jamming or blowing away small pieces of material. In addition, another arc-shaped guide plate 3 can be symmetrically installed below the end of the arc-shaped guide plate 3 according to actual needs. When the material rolls onto the filter chamber 5, it vibrates up and down along with the vibrating table 4 under the drive of the drive mechanism. Therefore, materials of appropriate size can fall into the collection chamber 7 through the filter chamber 5 and the adjusting filter plate 6. When the collection chamber 7 is finished collecting and removed, the adjusting filter plate 6 will be carried out by the rotating frame 9. This makes the through hole formed by the filter chamber 5 and the adjusting filter plate 6 larger, so that larger pieces of material can fall into the collection chamber 8 for collection. This makes the classification of material size clearer and more practical. After the rotating frame 9 is carried out, it no longer abuts against the inner wall of the frame 1. Under the drive of the elastic component, it will deflect and break away from the contact with the collection chamber 7.

[0015] In some embodiments, to prevent the adjusting filter plate 6 from moving on its own during screening, a friction block 11 is installed on the frame 1, and a brake block 12 is fixedly installed on the adjusting filter plate 6, with the friction block 11 abutting against the brake block 12. During material screening, since the adjusting filter plate 6 slides outwards, the overlap range between its filter holes and the filter holes of the filter chamber 5 increases. Therefore, the adjusting filter plate 6 may move outwards due to the impact of the material. The friction between the friction block 11 and the brake block 12 prevents the adjusting filter plate 6 from moving on its own. An elastic wear-resistant rubber pad can be installed at the bottom of the friction block 11 for braking, or the friction block 11 can be made of an elastic wear-resistant rubber pad.

[0016] In some embodiments, to facilitate the deflection of the rotating frame 9 and the re-braking of the adjusting filter plate 6 after it has slid out a certain distance, a groove 13 is provided on the brake block 12. The groove 13 has double inclined surfaces, so when it is pulled, the friction block 11 can use its own elasticity and the inclined surface of the groove 13 to squeeze the brake block 12 and the adjusting filter plate 6 a certain distance in a short time, thereby facilitating the deflection of the rotating frame 9. After the rotating frame 9 deflects, the adjusting filter plate 6 will also move outward a certain distance due to inertial force and the impact force of the material, so that the friction block 11 can re-abut against the brake block 12 along the other inclined surface.

[0017] In some embodiments, to protect the friction block 11, a guide frame 14 is fixedly installed on the frame 1, and the friction block 11 is slidably engaged in the guide frame 14. The top of the friction block 11 can abut against the inner wall of the guide frame 14, and the bottom can abut against the brake block 12, thereby improving elastic friction braking while the guide frame 14 can prevent the friction block 11 from bending and breaking.

[0018] In some embodiments, to further improve the braking effect of the friction block 11, an elastic component 2 15 is fixedly installed inside the guide frame 14. The elastic component 2 15 can be a spring, and its output end is connected to the friction block 11. Thus, under the pressure of the spring component 2 15, the braking effect of the friction block 11 is improved.

[0019] In some embodiments, an extension plate 16 is fixedly installed below the arc-shaped receiving plate 2 to collect dust blown off by the blower mechanism. Dust can be blown off along the extension plate 16 into the dust collection box.

[0020] The fixed connection and rotating installation in the above embodiments can all be achieved by welding, screw fasteners and other forms in the prior art, and the rotating installation can be achieved by bearings, circular rotating blocks and circular grooves. All of the above components are standard parts, and those that are not standard parts can also be specially customized, so the inventor will not elaborate further.

[0021] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0022] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
