Description

Technical Field

[0001] The utility model relates to the technical field of coal transfer and transportation, in particular to a coal transfer and transportation device. Background Art

[0002] Coal, a vital fossil energy source, is primarily formed from plant debris under pressure and high temperatures over geological time. It contains large amounts of carbon and smaller amounts of other elements (such as hydrogen, sulfur, oxygen, and nitrogen). Coal is primarily used for power generation, heating, steelmaking, and chemical production. Coal mining and transportation require the use of appropriate coal transfer and conveying equipment to transport coal over designated distances.

[0003] When transporting and transferring mined coal, due to factors such as groundwater and high-pressure water used in the mining process, the coal that needs to be transported after mining contains a large amount of water. Although the existing coal transfer and transportation equipment can dry the transported coal, its drying temperature cannot be adjusted accordingly according to the humidity of the coal that needs to be transported, which can easily lead to insufficient drying of the transported coal or excessive drying, resulting in the coal cracking.

[0028] The conveying housing unit 100 includes a coal conveying drum 101 and a feeding pipe 102 fixedly connected to one end of the coal conveying drum 101. A feeding hopper is fixedly provided at the upper end of the feeding pipe 102. The feeding hopper is configured in a funnel shape with a large opening at the upper end and a small opening at the lower end. The configuration of the funnel effectively solves the problem of coal easily spilling during the feeding process into the feeding pipe 102. A discharge nozzle 103 is fixedly connected to the end of the coal conveying drum 101 away from the feeding pipe 102.

[0029] Secondly, the conveying drive unit 200 includes a mesh cylinder 201 fixedly arranged inside the coal conveying cylinder 101 near one end of the feeding pipe 102, and the feeding pipe 102 is inserted downward into the mesh cylinder 201, and a drainage port 202 corresponding to the mesh cylinder 201 is opened on the lower side wall of the coal conveying cylinder 101, and a driving motor 203 is fixedly installed on one end of the coal conveying cylinder 101 away from the discharge nozzle 103. A plurality of evenly distributed smoothing rods 305 are provided on the inner wall of the coal conveying cylinder 101, and the plurality of smoothing rods 305 all correspond to the positions of the electric heating plates 302. Through the arrangement of the plurality of smoothing rods 305, the coal conveyed in the coal conveying cylinder 101 can be rolled and smoothed in cooperation with the variable diameter spiral conveying rod 204, so that the conveyed coal can receive good drying treatment, and the output shaft of the driving motor 203 passes through the end wall of the coal conveying cylinder 101 and is fixedly connected to the variable diameter spiral conveying rod 204;

[0030] Furthermore, the drying adjustment unit 300 is used to dry the coal conveyed by the coal conveying drum 101 .

[0031] The drying and regulating unit 300 includes an annular cover 301 fixedly mounted on the outer wall of the coal conveying cylinder 101 away from the side of the driving motor 203. The side wall of the annular cover 301 is inlaid with a transparent observation window 306, and the shifting rod 305 is set in a Y shape. The setting of the observation window 306 makes it easy for the staff to intuitively observe the movement of the electric heating plate 302 in the annular cover 301. The annular cover 301 is vertically slidably connected with the symmetrical electric heating plate 302. The electric heating plate 302 is made of mica sheet as the skeleton and insulation layer, supplemented by galvanized sheet or stainless steel sheet for support and protection, and can be made into plate, sheet, cylindrical, conical, cylindrical, circular, etc. Heating devices of various shapes, with a normal surface load of 2.5-3W and a temperature resistance of 500°C, are widely used in real life. The working principle thereof is not introduced in detail here.

The upper and lower sides of the annular cover 301 are threadedly connected with symmetrical adjusting screws 304. Each adjusting screw 304 is inserted into the annular cover 301 and is rotatably connected to the outer wall of the electric heating plate 302.

[0032] During use, the coal that needs to be transported is transported into the coal conveying cylinder 101 through the feeding pipe 102, and the output shaft of the driving motor 203 is started to drive the variable diameter spiral conveying rod 204 to rotate. In the process of driving the coal to roll forward, the excess water in the coal is discharged out of the coal conveying cylinder 101 through the mesh cylinder 201 and the drain port 202. According to the different water content of the coal, the adjusting screw 304 is turned to drive the electric heating plate 302 to move, and the distance between the electric heating plate 302 and the conveyed coal is adjusted to adjust the drying temperature of the coal by the electric heating plate 302, which effectively solves the defect of coal cracking caused by insufficient drying or excessive drying. The dried coal can be discharged through the discharge nozzle 103.
