[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0021] like Figure 1 、 Figure 2 As shown, the utility model provides an environmentally friendly integrated coal drying and purification equipment, including a shell 101, the four corners of the bottom of the shell 101 are fixedly connected to support legs 102, the middle of the bottom end of the shell 101 is fixedly connected to a discharge pipe 103, the outer wall of the discharge pipe 103 is fixedly connected to a solenoid valve 104, the top of the shell 101 is fixedly connected to a discharge hopper 105, a slag trough 106 is provided in the middle of the right side wall of the shell 101, and a slag collecting frame 107 fixedly connected to the right side wall of the shell 101 is provided on the right side of the slag trough 106, a vibration crushing component 2 is provided on the upper part of the interior of the shell 101, a purification and screening component 3 is provided in the middle position of the interior of the shell 101, and a stirring and drying component 4 is provided on the lower part of the interior of the shell 101.

[0022] During operation, coal is put into the shell 101 from the discharge hopper 105, first crushed by the vibration crushing component 2, then purified and screened in the purification and screening component 3, and finally stirred and dried in the stirring and drying component 4. The dried coal is discharged from the discharge pipe 103, and the waste slag is discharged from the slag discharge trough 106 into the slag collecting frame 107. At the same time, the support legs 102 can stably support the device, and the solenoid valve 104 is convenient for controlling the discharge of coal.

[0023] like Figure 3 、 Figure 4 As shown, the vibration crushing assembly 2 includes two grooves 201, and the left and right grooves 201 are respectively opened inside the left and right side walls of the shell 101. The inner top walls of the left and right grooves 201 are fixedly connected with a plurality of springs 202 distributed equidistantly in front and back. The bottoms of the plurality of springs 202 on the left and right sides are fixedly connected with a lifting plate 203 that is slidably connected to the inner wall of the groove 201. Rectangular grooves 207 are opened on the inner and outer walls of the left and right sides of the shell 101. The right side wall of the right lifting plate 203 is fixedly connected with two symmetrical servo motors 209. The opposite surfaces of the left and right lifting plates 203 are rotatably connected with two symmetrical servo motors 209. Crushing roller 208, the right ends of the front and rear crushing rollers 208 both penetrate the right side wall of the right lifting plate 203 and are fixedly connected to the output end of the servo motor 209, the right side wall of the shell 101 is fixedly connected to motor 1 204, the output end of motor 1 204 penetrates the inside of the right groove 201 and is fixedly connected to the rotating rod 205, the left end of the rotating rod 205 penetrates the left outer wall of the shell 101 and is fixedly connected to pulley 1 210, the front and rear ends of the rotating rod 205 are both rotatably connected to the shell 101, and the left and right sides of the outer wall of the rotating rod 205 are fixedly connected to crank 1 206 that fits with the bottom of the lifting plate 203.

[0024] When the coal needs to be crushed, two symmetrical servo motors 209 drive the two crushing rollers 208 to rotate relative to each other, and at the same time, motor 1 204 is started, and its output end drives the rotating rod 205 to rotate. The front and rear ends of the rotating rod 205 are rotatably connected to the shell 101, and the cranks 1 206 on the left and right sides of the outer wall rotate as the rotating rod 205 rotates, continuously hitting the bottom of the lifting plate 203, so that the lifting plate 203 vibrates up and down under the action of spring 1 202, thereby driving the crushing rollers 208 to vibrate up and down to crush the coal. The vibration can increase the impact force of the crushing rollers 208 on the coal, making it easier for the coal particles to be crushed into smaller particle sizes, which helps to improve the crushing efficiency and enables the equipment to complete the coal crushing work in a shorter time. At the same time, the crushed coal particles have an increased surface area, which is conducive to faster heat transfer to the inside of the coal during the drying process, thereby improving the drying efficiency.

[0025] like Figure 4As shown, the purification screening assembly 3 includes four fixed blocks 301, which are fixedly connected to the four corners of the middle part of the inner wall of the shell 101, and the tops of the four fixed blocks 301 are fixedly connected to spring 2 302. The tops of the four springs 2 302 are fixedly connected to a screen 303 located on the left side of the slag trough 106 and arranged obliquely. A connecting rod 306 rotatably connected to the left side wall of the shell 101 is provided below the pulley 1 210, and the left end of the connecting rod 306 is fixedly connected to pulley 2 305. The outer walls of pulley 1 210 and pulley 2 305 are provided with belts. The right end of the connecting rod 306 passes through the interior of the shell 101 and is fixedly connected to crank 2 307 which fits the bottom of the screen 303.

[0026] When the coal needs to be screened and purified, the pulley 1 210 in the vibration crushing assembly 2 rotates, and the pulley 2 305 is driven to rotate by the belt. The pulley 2 305 is fixed to the left end of the connecting rod 306, and the right end of the connecting rod 306 passes through the interior of the shell 101 and is fixedly connected to the crank 2 307. The crank 2 307 continuously hits the bottom of the screen 303, so that the screen 303 vibrates up and down under the action of the spring 2 302, and the crushed coal is purified and screened. The waste slag is discharged from the slag trough 106 into the slag collecting frame 107, thereby effectively filtering out impurities such as soil, stones, and wood chips in the coal, thereby improving the purity of the coal.

[0027] like Figure 5 As shown, the stirring and drying component 4 includes a fixed plate 401 and a motor 2 404. The left side wall of the fixed plate 401 is fixedly connected to the bottom of the right side wall of the shell 101. The left side wall of the motor 2 404 is fixedly connected to the bottom of the right side wall of the shell 101. The top of the fixed plate 401 is fixedly connected to a hot air blower 402. The top air outlet of the hot air blower 402 is fixedly connected to an air outlet pipe 403. The end of the air outlet pipe 403 away from the hot air blower 402 is rotatably connected to a hollow ventilation rod 406. The hollow The right side of the outer wall of the ventilation rotating rod 406 is fixedly connected to bevel gear 1 405, the top of bevel gear 1 405 is meshedly connected to bevel gear 2 407, the top of bevel gear 2 407 is fixedly connected to the output end of motor 2 404, the left side of bevel gear 2 407 is meshedly connected to bevel gear 3 408, the inner wall of bevel gear 3 408 is fixedly connected to a hollow rotating rod 409 rotatably connected to the right side wall of the shell 101, and the outer wall of the hollow ventilation rotating rod 406 is rotatably connected to the inner wall of the hollow rotating rod 409.

[0028] like Figure 5As shown, the left end of the hollow ventilation rotating rod 406 passes through the interior of the shell 101 and the outer wall is fixedly connected to several hollow stirring rods 411 distributed equidistantly on the left and right. Several air outlet holes 412 distributed equidistantly up and down are opened on the front and back sides of the several hollow stirring rods 411. The end of the hollow ventilation rotating rod 406 away from the bevel gear 405 is rotatably connected to the left inner wall of the shell 101. The left end of the hollow rotating rod 409 passes through the interior of the shell 101 and the outer wall is fixedly connected to a stirring frame 410 distributed alternately with several hollow stirring rods 411. A semicircular heating barrel 413 fixedly connected to the inner wall of the shell 101 is provided below the hollow stirring rod 411. Several heating pipes distributed equidistantly on the left and right are fixedly connected to the bottom of the outer wall of the semicircular heating barrel 413. A discharge pipe 414 is fixedly connected to the bottom of the semicircular heating barrel 413, and an outer wall of the discharge pipe 414 is fixedly connected to an electromagnetic valve 2 415.

[0029] When the coal needs to be dried, the motor 2 404 is started, and its output end drives the bevel gear 2 407 to rotate, so that the bevel gear 1 405 drives the hollow ventilation rotating rod 406 to rotate, and at the same time the bevel gear 2 407 drives the bevel gear 3 408 to rotate, thereby rotating the hollow rotating rod 409, and the hollow stirring rod 411 on the hollow ventilation rotating rod 406 and the stirring frame 410 on the hollow rotating rod 409 stir the coal. At the same time, the hot air blower 402 is started, and the hot air generated by the hot air blower 402 enters the hollow ventilation rotating rod 406 from the air outlet pipe 403. The air is blown out from the air outlet 412 of the hollow stirring rod 411 to dry the coal. At the same time, the heating pipe at the bottom of the outer wall of the semicircular heating barrel 413 further heats and dries the coal. The dried coal is discharged from the discharge pipe 414 at the bottom of the semicircular heating barrel 413. The solenoid valve 415 is convenient for controlling its discharge. By fully stirring the coal, all parts of the coal can be evenly exposed to the hot air ejected from the air outlet 412, which accelerates the evaporation of water in the coal and greatly improves the drying efficiency.

[0030] It should be noted that the second solenoid valve 415, the first solenoid valve 104, and the hot air blower 402 are all existing technologies and will not be explained in detail here.

[0031] The following is a detailed description of the working principle of this environmentally friendly integrated coal drying and purification equipment.

[0032] like Figure 1-5As shown, when the coal needs to be crushed, two symmetrical servo motors 209 drive the two crushing rollers 208 to rotate relative to each other, and at the same time, motor 1 204 is started, and its output end drives the rotating rod 205 to rotate. The front and rear ends of the rotating rod 205 are rotatably connected to the shell 101, and the cranks 1 206 on the left and right sides of the outer wall rotate as the rotating rod 205 rotates, continuously hitting the bottom of the lifting plate 203, so that the lifting plate 203 vibrates up and down under the action of spring 1 202, thereby driving the crushing rollers 208 to vibrate up and down to crush the coal. The vibration can increase the impact force of the crushing rollers 208 on the coal, making it easier for the coal particles to be crushed into smaller particle sizes, which helps to improve the crushing efficiency and enables the equipment to complete the coal crushing work in a shorter time. At the same time, the crushed coal particles have an increased surface area, which is conducive to faster heat transfer to the coal interior during the drying process, thereby improving the drying efficiency.

[0033] When the coal needs to be screened and purified, the pulley 1 210 in the vibration crushing assembly 2 rotates, and the pulley 2 305 is driven to rotate by the belt. The pulley 2 305 is fixed to the left end of the connecting rod 306, and the right end of the connecting rod 306 passes through the interior of the shell 101 and is fixedly connected to the crank 2 307. The crank 2 307 continuously hits the bottom of the screen 303, so that the screen 303 vibrates up and down under the action of the spring 2 302, and the crushed coal is purified and screened. The waste slag is discharged from the slag trough 106 into the slag collecting frame 107, thereby effectively filtering out impurities such as soil, stones, and wood chips in the coal, thereby improving the purity of the coal.

[0034] When the coal needs to be dried, the motor 2 404 is started, and its output end drives the bevel gear 2 407 to rotate, so that the bevel gear 1 405 drives the hollow ventilation rotating rod 406 to rotate, and at the same time the bevel gear 2 407 drives the bevel gear 3 408 to rotate, thereby rotating the hollow rotating rod 409, and the hollow stirring rod 411 on the hollow ventilation rotating rod 406 and the stirring frame 410 on the hollow rotating rod 409 stir the coal. At the same time, the hot air blower 402 is started, and the hot air generated by the hot air blower 402 enters the hollow ventilation rotating rod 406 from the air outlet pipe 403. The air is blown out from the air outlet 412 of the hollow stirring rod 411 to dry the coal. At the same time, the heating pipe at the bottom of the outer wall of the semicircular heating barrel 413 further heats and dries the coal. The dried coal is discharged from the discharge pipe 414 at the bottom of the semicircular heating barrel 413. The solenoid valve 415 is convenient for controlling its discharge. By fully stirring the coal, all parts of the coal can be evenly exposed to the hot air ejected from the air outlet 412, which accelerates the evaporation of water in the coal and greatly improves the drying efficiency.

[0035] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
