Description

Technical Field

[0001] The utility model relates to the technical field of coal processing equipment, in particular to a drying device for preventing material leakage at a cylinder connection. Background Art

[0002] A coal dryer is a device used to remove moisture from coal. It is primarily used to dry high-moisture fuels such as coal slime and clean coal slurry to meet subsequent combustion or processing requirements. A coal dryer heats the coal, evaporating and discharging the moisture, thereby reducing its moisture content, increasing its calorific value, and improving its transport efficiency. Coal dryers typically utilize a drum design, where high-temperature hot air blows through the drum, drying the coal through heat exchange. The drum dryer's transmission system includes a motor, reducer, gears, and ring gear. The feed and discharge mechanisms and sealing devices ensure the continuity and efficiency of the drying process. Coal dryers are widely used in various industries, particularly in the chemical, metallurgical, building materials, and light industries. These industries frequently dry materials during production, and the high efficiency and energy-saving features of coal dryers make them essential equipment in these fields.

[0003] The commonly used rotary drum dryer uses a flange connection between the drum and the gear ring, resulting in poor sealing performance. This can easily lead to material leakage at the connection between the gear ring and the drum during operation. To address this issue, the present utility model provides a drying device that prevents material leakage at the connection between the drum and the gear ring, thereby resolving the problem of material leakage at the connection between the gear ring and the drum during operation. Utility Model Content

[0004] The purpose of the utility model is to provide a drying device which can prevent material leakage at the connection between the cylinder body, so as to solve the problem of material leakage at the connection between the gear ring and the cylinder body during the operation of the dryer.

[0005] To achieve the above-mentioned purpose, the basic solution provided by the utility model is: a drying device for preventing material leakage at the connection of the cylinder, comprising a tugboat and two cylinders, the tugboat supporting a rolling ring, the rolling ring and the cylinder being bolted together, a flange welded on one of the cylinders, a gear ring being bolted to the flange, a gear meshing link being connected on the gear ring, a motor being provided on the gear, a plurality of mounting blocks being provided on one end of the two cylinders, a trapezoidal protrusion being provided on the mounting block of one of the cylinders, a trapezoidal groove being provided on the mounting block of the other cylinder, the trapezoidal protrusion being engaged with the trapezoidal groove, a buckle being hinged on the mounting block provided with the trapezoidal groove, and the buckle being clamped to the mounting block provided with the trapezoidal protrusion.

[0006] The working principle of the utility model is as follows: when in use, first, the trapezoidal protrusion on one cylinder mounting block is nested into the trapezoidal groove on the other cylinder mounting block, and then the buckle is snapped into the slot, and then the roller on the cylinder is placed on the tugboat, so that the tugboat supports the cylinder through the roller, and then the gear ring and the flange on the cylinder are tightened and fixed with bolts, and then the gear is engaged with the gear ring to complete the installation, and then the motor is turned on to rotate the cylinder to carry out the coal drying work.

[0007] The beneficial effect of the present invention is that the present invention realizes the connection between the cylinders by arranging connecting pieces on the outer wall of the cylinder. Compared with the traditional coal dryer, this design makes the cylinders tightly connected, and solves the problem of material leakage at the connection between the gear ring and the cylinder during the operation of the dryer.

[0008] Option 2, which is the preferred option of the basic option, is that a mounting block of the cylinder is provided with a slot, and the buckle is engaged with the slot; the buckle is engaged in the slot to prevent the buckle from slipping off.

[0009] Option three is the preferred option of the basic option. A rubber ring is provided at the connection between the two cylinders. The rubber ring can play a sealing role, and the rubber ring has better elasticity and wear resistance and a long service life.

[0010] Option 4 is the preferred option of the basic option. The trapezoidal groove and the trapezoidal protrusion are both provided with through holes, and the trapezoidal groove and the trapezoidal protrusion are bolted together. The trapezoidal groove and the trapezoidal protrusion are connected by bolts, which is not only convenient for disassembly and assembly but also has the characteristics of reliable connection and low cost.

[0011] Option 5 is the preferred option of the basic option. The motor is a reduction motor, model JS40. The reduction motor can not only adjust the speed of the dryer, but also ensure the smooth operation of the dryer. The reduction motor has a strong anti-overload capability and can effectively protect the equipment from damage. BRIEF DESCRIPTION OF THE DRAWINGS
