[0002] Coal slime refers to a semi-solid substance formed by coal powder containing water. It is a product in the coal production process. During the processing of coal slime, it is necessary to use a dewatering screen to dehydrate, deslim and remove the coal slime to improve the quality of the clean coal.

[0003] For example, the utility model: "Coal slime separation and dehydration screen", with the announcement number: "CN217988555U", is provided with a support frame consisting of an upper and lower group of frames, assisted by a rotating shaft and a hydraulic column, which facilitates the adjustment of the distance between the two groups of frame supports according to the needs of coal slime screening, thereby realizing the upper and lower height adjustment of the screen box close to the inclined plate outlet, so as to facilitate more delicate separation and screening of the coal slime. However, during the implementation of this patent, since the beam plate is fixedly installed on the screen box, the wind blown out of the air outlet can only be transmitted to the designated position through the wind guide plate, and the gas cannot be evenly blown to different positions of the polyurethane screen plate, which is prone to dead corners, making it difficult to shake the polyurethane screen plate and quickly separate the water in the coal slime. Therefore, the research and development of new coal slime separation and dehydration screens has received more and more attention from researchers. Utility Model Content

[0022] In this implementation:

[0023] Furthermore, a bottom plate 22 is installed at the bottom of the screen bin 1 near one end of the second sliding component 21, and a spring 20 is installed on the top of the bottom plate 22. The end of the spring 20 away from the bottom plate 22 is connected to the connecting plate 17. When in use, the vibration motor 19 works to generate vibration, and the spring 20 is used in combination to enable the connecting plate 17 to drive the screen 4 to shake repeatedly.

[0024] Furthermore, the bottom of the diversion bin 6 is evenly installed with injection pipes 5, and the air pump 13 blows the gas into the diversion bin 6 through the outlet pipe 12, and blows the gas evenly onto the coal slime through the injection pipe 5, which can not only blow off the water on the coal slime, but also air-dry the coal slime.

[0025] Furthermore, a push plate 16 is installed at the output end of the electric pneumatic cylinder 18, and the electric pneumatic cylinder 18 pushes the push plate 16 to move. The push plate 16 can push the coal slime above the screen 4 into the opening 3, and the coal slime can be discharged from the screen bin 1 through the opening 3.

[0027] Furthermore, a drain pipe 23 is installed at the bottom of the sieve bin 1 at one end away from the through opening 3 , and water can be discharged from the inside of the sieve bin 1 through the drain pipe 23 .

[0028] Furthermore, a feed port 15 is provided at one end of the top of the screen bin 1 close to the second sliding assembly 21 , so as to facilitate the addition of coal slime into the screen bin 1 .

[0029] Working principle:

[0030] When in use, the device is powered on, and the staff can feed the coal slurry onto the screen 4 through the feed port 15, and the water can pass through the screen 4 and fall below the screen 4, and the water can be discharged from the screen bin 1 through the drain pipe 23;

[0031] The staff can start the vibration motor 19 through the control panel 2, and the vibration motor 19 generates vibration when working, and the vibration motor 19 drives the connecting plate 17 to vibrate, so that the connecting plate 17 is stressed and slides on the second sliding component 21, and the spring 20 is used in conjunction, so that the connecting plate 17 can drive the screen 4 to shake repeatedly, and the water inside the coal slime can be shaken off by the vibration of the screen 4, so that the water is quickly separated from the coal slime;

[0032] The staff can start the air pump 13 through the control panel 2, and the air pump 13 blows the gas into the diversion bin 6 through the outlet pipe 12, and blows the gas evenly onto the coal slime through the air injection pipe 5, which can not only blow off the water on the coal slime, but also air dry the coal slime;

[0033] At the same time, the staff can start the driving motor 26 through the control panel 2, so that the driving motor 26 drives the turntable 7 to rotate at a constant speed through the rotating shaft 25, and the turntable 7 drives the fixing rod 27 to rotate. Since the fixing rod 27 is installed on the inner ring of the bearing 24, and the connecting rod 10 is installed on the outer ring of the bearing 24, the connecting rod 10 can rotate independently outside the fixing rod 27 through the bearing 24, so that the connecting rod 10 can always face one end of the sliding plate 11;

[0034] When the fixing rod 27 rotates to one end away from the fixing plate 8, the fixing rod 27 drives the connecting rod 10 to move together through the bearing 24, so that the connecting rod 10 is subjected to force and pushes the sliding plate 11 to move, thereby driving the guide chamber 6 to move;

[0035] When the fixing rod 27 rotates to one end close to the fixing plate 8, the fixing rod 27 drives the connecting rod 10 to move together through the bearing 24, so that the connecting rod 10 is subjected to force and pulls the sliding plate 11 to move, thereby driving the guide chamber 6 to move;

[0036] Since the driving motor 26 drives the turntable 7 to rotate at a constant speed through the rotating shaft 25, the connecting rod 10 can repeatedly push and pull the sliding plate 11 to move, and the guide bin 6 can be reciprocated to different positions above the screen 4, so that the gas can be evenly blown onto the coal slime at different positions, which is conducive to drying the coal slime and fully separating the coal slime from the water;

[0037] After dehydration is completed, the staff can start the electric pneumatic cylinder 18 through the control panel 2, so that the electric pneumatic cylinder 18 pushes the push plate 16 to move, and the push plate 16 can push the coal slime above the screen 4 into the opening 3, and the coal slime can be discharged from the screen bin 1 through the opening 3.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
