when the motor 52 is started, the motor 52 drives the cam 54 to rotate through the rotating shaft 53, the cam 54 drives the corresponding first moving plate 41, second moving plate 42 and third moving plate 43 to move leftwards respectively, the first moving plate 41, second moving plate 42 and third moving plate 43 extrude the spring 47 in the groove 21, the spring 47 pushes the first moving plate 41, second moving plate 42 and third moving plate 43 to move rightwards due to the elasticity of the spring, the rotating shaft 53 rotates to drive the cam 54 to rotate, and pushes the corresponding first moving plate 41, second moving plate 42 and third moving plate 43 to move leftwards again, so that the first moving plate 41, second moving plate 42 and third moving plate 43 do left-right reciprocating motion, and the first sieve box 44, second sieve box 45 and third sieve box 46 are connected with the first moving plate 41, second moving plate 42 and third moving plate 43 respectively in a sliding manner, so that the first moving plate 41, second moving plate 42 and third moving plate 43 do left-right reciprocating motion, The second moving plate 42 and the third moving plate 43 drive the first sieve box 44, the second sieve box 45 and the third sieve box 46 to do reciprocating motion, and meanwhile, the travel of the first sieve box 44, the second sieve box 45 and the third sieve box 46 on the first moving plate 41, the second moving plate 42 and the third moving plate 43 is smaller than the distance between the first moving plate 41, the second moving plate 42 and the third moving plate 43 in a left-right moving mode, so that the first sieve box 44, the second sieve box 45 and the third sieve box 46 on the first moving plate 41, the second moving plate 42 and the third moving plate 43 are prevented from being relatively static due to the existence of the sliding grooves 411;
when gas coal with different sizes enters from a feed inlet above the shell 2 and then falls into the first sieve box 44, the gas coal with different sizes in the first sieve box 44 is influenced by the Brazilian drupe effect along with the reciprocating motion of the left and right of the first sieve box 44, the smaller gas coal is positioned at the lower layer of the first sieve box 44 due to small size, the larger gas coal is positioned at the upper layer of the first sieve box 44 due to large size, the larger gas coal positioned at the upper layer of the first sieve box 44 falls into the second sieve box 45 along with the continuous entering of the gas coal into the shell 2, and the larger gas coal positioned at the upper layer of the second sieve box 45 falls into the third sieve box 46 along with the continuous entering of the gas coal, and the largest gas coal positioned at the upper layer of the third sieve box 46 falls into the bottom of the shell 2, so that most of the gas coal with the largest volume is positioned at the bottommost of the shell 2 closest to the heater 3, and most of the gas coal with the same volume is positioned at the middle of the shell 2 far away from the heater 3, most of the gas coal with the minimum volume is positioned on the uppermost layer of the shell 2 which is farthest away from the heater 3, so that the effect of screening the gas coal with different sizes is realized, the carbonization furnace is more efficient in heating the gas coal, the effect of saving energy is achieved, and the gas coal cannot coke in the carbonization furnace with the layered structure, so that the gas coal is continuously conveyed into the shell 2 until the height of the gas coal is equal to the height of the first sieve box 44, and the effect of facilitating coking is achieved. Due to the reciprocating motion of the first sieve box 44, the second sieve box 45 and the third sieve box 46, the screened gas coal is dispersed more uniformly, so that the gas coal is heated uniformly.
As a specific embodiment of the present invention, the volumes of the first sieve box 44, the second sieve box 45, and the third sieve box 46 are sequentially increased.
When the larger gas coal in the first sieve box 44 and the second sieve box 45 falls downwards, in order to enable the falling gas coal to fall into the second sieve box 45 and the third sieve box 46 respectively, the sizes of the first sieve box 44, the second sieve box 45 and the third sieve box 46 are sequentially increased from top to bottom, so that most of the gas coal falling from the first sieve box 44 and the second sieve box 45 can fall into the second sieve box 45 and the third sieve box 46 respectively, and the second sieve box 45 and the third sieve box 46 can better screen the gas coal with different sizes.
As a specific embodiment of the present invention, a round bar 6 is fixedly connected to the first sieve box 44 and the second sieve box 45, sliding grooves 411 are respectively formed on the first moving plate 41 and the second moving plate 42, and two ends of the round bar 6 are located in the sliding grooves 411.
According to the invention, the round rods 6 are fixedly connected to the first sieve box 44 and the second sieve box 45, the sliding grooves 411 are respectively formed in the first moving plate 41 and the second moving plate 42, so that two ends of each round rod 6 are positioned in the sliding grooves 411, and the round rods 6 are fixedly connected to the bottoms of the first sieve box 44 and the second sieve box 45, so that when the first sieve box 44 and the second sieve box 45 move, the first sieve box 44 and the second sieve box 45 can swing at a certain angle, and larger gas coal in the first sieve box 44 and the second sieve box 45 can quickly fall out from the first sieve box 44 and the second sieve box 45, thereby achieving the effect of quickly screening gas coal with different sizes.
In an embodiment of the present invention, the round bar 6 is located at a middle position between the first sieve box 44 and the second sieve box 45.
In an embodiment of the present invention, a balance weight 7 is fixedly connected to the round bar 6.
Because the first sieve box 44 and the second sieve box 45 need to swing and shake at a certain angle while moving, in order to prevent the first sieve box 44 and the second sieve box 45 from turning on one side, the invention fixes the round rod 6 at the middle position of the first sieve box 44 and the second sieve box 45, and the round rod 6 is fixedly connected with the balance block 7, so that the balance effect of the first sieve box 44 and the second sieve box 45 is ensured under the condition of multidirectional movement.
As a specific embodiment of the present invention, the inner surfaces of the first sieve box 44, the second sieve box 45, and the third sieve box 46 are fixedly connected with the stirring members 8.
According to the invention, the stirring piece 8 is fixedly connected to the inner surfaces of the first sieve box 44, the second sieve box 45 and the third sieve box 46, the first sieve box 44, the second sieve box 45 and the third sieve box 46 drive gas coal to collide with the stirring piece 8 while reciprocating, and in the gas coal shaking process, the stirring piece 8 can further stir the shaken gas coal, so that the gas coal is heated more uniformly.
As a specific embodiment of the present invention, the first sieve box 44, the second sieve box 45, and the third sieve box 46 have a third through hole 441 at the bottom thereof.
Because tar is generated during gas coal coking, the bottom of the first sieve box 44, the second sieve box 45 and the third sieve box 46 is provided with the third through hole 441, so that the tar in the first sieve box 44, the second sieve box 45 and the third sieve box 46 can flow out in time.
In an embodiment of the present invention, the first moving plate 41 and the second moving plate 42 have a hollow structure.
According to the invention, the structure of the first moving plate 41 and the second moving plate 42 is made into a hollow structure, so that when gas coal in the first sieve box 44 and the second sieve box 45 falls, the gas coal can respectively pass through the hollow parts of the first moving plate 41 and the second moving plate 42 and directly fall into the second sieve box 45 and the third sieve box 46 for screening, thereby achieving the effect of rapid screening.
In a specific embodiment of the present invention, the material of the sieving assembly 4, the power assembly 5, the round rod 6, the balance weight 7 and the stirring member 8 is a high temperature resistant material.
Because the working temperature of the invention is 500-1000 ℃, the materials of the sieving component 4, the power component 5, the round rod 6, the balance weight 7 and the stirring piece 8 are high-temperature resistant materials, such as high-speed steel, 3Cr2W8V, 5CrNiMo, 5CrMnMo and the like, so that the sieving component can normally move.

when the motor 52 is started, the motor 52 drives the cam 54 to rotate through the rotating shaft 53, the cam 54 drives the corresponding first moving plate 41, second moving plate 42 and third moving plate 43 to move leftwards respectively, the first moving plate 41, second moving plate 42 and third moving plate 43 extrude the spring 47 in the groove 21, the spring 47 pushes the first moving plate 41, second moving plate 42 and third moving plate 43 to move rightwards due to the elasticity of the spring, the rotating shaft 53 rotates to drive the cam 54 to rotate, and pushes the corresponding first moving plate 41, second moving plate 42 and third moving plate 43 to move leftwards again, so that the first moving plate 41, second moving plate 42 and third moving plate 43 do left-right reciprocating motion, and the first sieve box 44, second sieve box 45 and third sieve box 46 are connected with the first moving plate 41, second moving plate 42 and third moving plate 43 respectively in a sliding manner, so that the first moving plate 41, second moving plate 42 and third moving plate 43 do left-right reciprocating motion, The second moving plate 42 and the third moving plate 43 drive the first sieve box 44, the second sieve box 45 and the third sieve box 46 to do reciprocating motion, and meanwhile, the travel of the first sieve box 44, the second sieve box 45 and the third sieve box 46 on the first moving plate 41, the second moving plate 42 and the third moving plate 43 is smaller than the distance between the first moving plate 41, the second moving plate 42 and the third moving plate 43 in a left-right moving mode, so that the first sieve box 44, the second sieve box 45 and the third sieve box 46 on the first moving plate 41, the second moving plate 42 and the third moving plate 43 are prevented from being relatively static due to the existence of the sliding grooves 411;
when gas coal with different sizes enters from a feed inlet above the shell 2 and then falls into the first sieve box 44, the gas coal with different sizes in the first sieve box 44 is influenced by the Brazilian drupe effect along with the reciprocating motion of the left and right of the first sieve box 44, the smaller gas coal is positioned at the lower layer of the first sieve box 44 due to small size, the larger gas coal is positioned at the upper layer of the first sieve box 44 due to large size, the larger gas coal positioned at the upper layer of the first sieve box 44 falls into the second sieve box 45 along with the continuous entering of the gas coal into the shell 2, and the larger gas coal positioned at the upper layer of the second sieve box 45 falls into the third sieve box 46 along with the continuous entering of the gas coal, and the largest gas coal positioned at the upper layer of the third sieve box 46 falls into the bottom of the shell 2, so that most of the gas coal with the largest volume is positioned at the bottommost of the shell 2 closest to the heater 3, and most of the gas coal with the same volume is positioned at the middle of the shell 2 far away from the heater 3, most of the gas coal with the minimum volume is positioned on the uppermost layer of the shell 2 which is farthest away from the heater 3, so that the effect of screening the gas coal with different sizes is realized, the carbonization furnace is more efficient in heating the gas coal, the effect of saving energy is achieved, and the gas coal cannot coke in the carbonization furnace with the layered structure, so that the gas coal is continuously conveyed into the shell 2 until the height of the gas coal is equal to the height of the first sieve box 44, and the effect of facilitating coking is achieved. Due to the reciprocating motion of the first sieve box 44, the second sieve box 45 and the third sieve box 46, the screened gas coal is dispersed more uniformly, so that the gas coal is heated uniformly.
When the larger gas coal in the first sieve box 44 and the second sieve box 45 falls downwards, in order to enable the falling gas coal to fall into the second sieve box 45 and the third sieve box 46 respectively, the sizes of the first sieve box 44, the second sieve box 45 and the third sieve box 46 are sequentially increased from top to bottom, so that most of the gas coal falling from the first sieve box 44 and the second sieve box 45 can fall into the second sieve box 45 and the third sieve box 46 respectively, and the second sieve box 45 and the third sieve box 46 can better screen the gas coal with different sizes.
According to the invention, the round rods 6 are fixedly connected to the first sieve box 44 and the second sieve box 45, the sliding grooves 411 are respectively formed in the first moving plate 41 and the second moving plate 42, so that two ends of each round rod 6 are positioned in the sliding grooves 411, and the round rods 6 are fixedly connected to the bottoms of the first sieve box 44 and the second sieve box 45, so that when the first sieve box 44 and the second sieve box 45 move, the first sieve box 44 and the second sieve box 45 can swing at a certain angle, and larger gas coal in the first sieve box 44 and the second sieve box 45 can quickly fall out from the first sieve box 44 and the second sieve box 45, thereby achieving the effect of quickly screening gas coal with different sizes.
Because the first sieve box 44 and the second sieve box 45 need to swing and shake at a certain angle while moving, in order to prevent the first sieve box 44 and the second sieve box 45 from turning over, the invention fixes the round rod 6 at the middle position of the first sieve box 44 and the second sieve box 45, and the round rod 6 is fixedly connected with the balance block 7, so that the first sieve box 44 and the second sieve box 45 can ensure the balance effect under the condition of multidirectional movement.
According to the invention, the inner surfaces of the first sieve box 44, the second sieve box 45 and the third sieve box 46 are rotatably connected with the stirring piece 8, the first sieve box 44, the second sieve box 45 and the third sieve box 46 drive gas coal to collide with the stirring piece 8 while reciprocating, and the stirring piece 8 can further stir the swaying gas coal in the swaying process of the gas coal, so that the gas coal is heated more uniformly.
Because tar is generated during gas coal coking, the bottom of the first sieve box 44, the second sieve box 45 and the third sieve box 46 is provided with the third through hole 441, so that the tar in the first sieve box 44, the second sieve box 45 and the third sieve box 46 can flow out in time.
According to the invention, the structure of the first moving plate 41 and the second moving plate 42 is made into a hollow structure, so that when gas coal in the first sieve box 44 and the second sieve box 45 falls, the gas coal can respectively pass through the hollow parts of the first moving plate 41 and the second moving plate 42 and directly fall into the second sieve box 45 and the third sieve box 46 for screening, thereby achieving the effect of rapid screening.
The working temperature of the invention is 500-1000 ℃, so the materials of the sieving component 4, the power component 5, the round rod 6, the balance weight 7 and the stirring piece 8 are high temperature resistant materials, such as high speed steel, 3Cr2W8V, 5CrNiMo, 5CrMnMo and the like, so that the materials can normally move.
