[0002] Coal is the main energy source for people's lives. Coal mined directly from mines is called raw coal. Impurities are inevitably mixed in during the generation, mining and transportation of raw coal. The deeper the bottom, the worse the quality of the raw coal. The quality of coal is also different. In order to reduce impurities, coal slime is formed after deep processing of coal.

[0004] The applicant has found that there are still some problems that need to be improved in the above technical scheme. For example, in the process of extruding and dehydrating the coal slime, the coal slime after extrusion and dehydration will still be mixed with some water. The water mixed in the coal slime will result in the coal slime not being able to be used directly in the future. The extruded coal slime needs to be further dried to ensure that the water in the coal slime is removed. However, drying the extruded coal slime requires adding a new process, which brings inconvenience to the production personnel. For this reason, we propose a coal slime hydraulic dehydrator to save the drying process, thereby improving the production efficiency of the production personnel. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 , Figure 2 as well as Figure 4 A coal slime hydraulic dehydrator in this embodiment includes a bottom plate 1; a squeezing bin 2 is fixed on the top surface of the bottom plate 1, a feed pipe is connected to the upper surface of the squeezing bin 2, and the feed pipe is funnel-shaped; a dehydration mechanism is provided on the top surface of the bottom plate 1, and a drying mechanism is also provided on the top surface of the bottom plate 1.

[0023] Among them, the dehydration mechanism includes a first cylinder 3 installed on the top surface of the base plate 1 and close to its right end through a bracket, a fixed plate 5 is fixed to the output end of the first cylinder 3, and no less than three connecting rods 6 are fixed to the left end of the fixed plate 5, and a drainage plate 7 is fixed to the left ends of multiple connecting rods 6. The left end of the drainage plate 7 is provided with multiple drainage holes, and the multiple drainage holes all penetrate and extend to the right end of the drainage plate 7. An extrusion plate is fixed to the right end of the second cylinder 4, and sealing gaskets are fixed to the surrounding walls of the extrusion plate, the drainage plate 7 and the fixed plate 5. The left end of the drainage plate 7 is covered with a drainage cloth 8, and the mesh number of the drainage cloth 8 is 20 meshes; the dehydration mechanism also includes a second cylinder 4 fixed to the top surface of the base plate 1 and close to its left end through a bracket.

[0024] During operation, first, coal slime is put in through the feed pipe arranged on the extrusion bin 2, and then the coal slime will fall into the extrusion bin 2, and then by starting the first cylinder 3 and the second cylinder 4 at the same time, the output ends of the first cylinder 3 and the second cylinder 4 will move into the extrusion bin 2, and then when the extrusion plate installed at the right end of the second cylinder 4 contacts the coal slime, the drainage cloth 8 installed at the left end of the first cylinder 3 squeezes the coal slime. Since the coal slime is squeezed, the moisture mixed in the coal slime will move to the right through the small holes on the drainage cloth 8, and then the moisture will move to between the fixed plate 5 and the drainage plate 7 through the multiple drainage holes opened on the drainage plate 7; and when the moisture between the fixed plate 5 and the drainage plate 7 needs to be discharged from the extrusion bin 2, by resetting the first cylinder 3 and the second cylinder 4, the fixed plate 5 and the drainage plate 7 can be driven to move out of the extrusion bin 2, and the moisture can be taken out of the extrusion bin 2, thereby realizing the extrusion dehydration of the coal slime.

[0025] However, after squeezing and dragging water, the coal slime is temporarily stored in the squeezing bin 2. By further starting the first cylinder 3, the first cylinder 3 will push the coal slime in the squeezing bin 2, so that the coal slime falls into the feed hopper arranged on the conveying box 9 through the through hole at the left end of the squeezing bin 2.

[0026] It should be noted that, in the present invention, in order to ensure the stroke of the first cylinder 3 and the second cylinder 4, the first cylinder 3 and the second cylinder 4 are both multi-stage cylinders.

[0028] During operation, the material enters the conveying box 9 through the hopper installed on the conveying box 9, and further by starting the heating wire 14, the heating wire 14 will heat the heating box 10 when it is working. When the heating box 10 is heated, the heat will be transferred to the conveying box 9 fixed with the heating box 10, and further by starting the servo motor 11, the rotation of the output shaft of the servo motor 11 will drive the spiral conveying piece 13 fixed to the output shaft of the servo motor 11 to rotate, thereby conveying the coal slime in the conveying box 9. During the conveying process, because the conveying box 9 is heated, the coal slime in the conveying box 9 will be heated, thereby achieving the purpose of further drying the coal slime, and after heating, the coal slime in the conveying box 9 will be conveyed to the outside of the conveying box 9 through the discharge hole set at the right end of the conveying box 9, thereby achieving the purpose of discharging.
