When the combination of technical solutions results in contradictions or is impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0048] The present invention provides the following embodiments:

[0049] Embodiment 1

[0050] The embodiment of the present invention provides a scale-hopper type one-step bin dry slag machine, as Figures 1-5 shown, including a machine body 1, a slag well 2 is provided on the machine body 1, a slag inlet hopper 200 is provided on the slag well 2, two symmetrically arranged shut-off doors 201 are provided in the slag well 2, the top surface of the shut-off door 201 is in an arc shape, a scale-hopper type slag conveyor belt 202 is provided in the machine body 1, a cold air conveying pipe 203 is provided in the machine body 1, and a slag crusher 3 is provided at the output end of the scale-hopper type slag conveyor belt 202.

[0051] The working principle and beneficial effects of the above technical solution are as follows: During operation, the shut-off door 201 is opened, and the slag falls from the slag inlet hopper 200 into the slag well 2 and then onto the scale-hopper type slag conveyor belt 202. The slag is sent into the slag crusher 3 through the scale-hopper type slag conveyor belt 202. During the process of the scale-hopper type slag conveyor belt 202 transporting the slag, the cold air conveying pipe 203 introduces cold air into the bottom of the scale-hopper type slag conveyor belt 202, and the cold air penetrates the scale-hopper type slag conveyor belt 202 from bottom to top. After the cold air takes away the heat on the slag, it rises in temperature and flows into the slag well 2, thereby improving the thermal efficiency of the boiler. Since the top surface of the shut-off door 201 is in an arc shape, when the slag falls on the top surface of the shut-off door 201, due to the effect of the arc surface, the slag will roll along the arc surface onto the scale-hopper type slag conveyor belt 202, and at the same time, the step of manually cleaning the slag on the shut-off door is omitted;

[0052] The present invention has a function of penetrating heat exchange, improving heat exchange performance and high-temperature slag heat recovery efficiency, adopting a scale-hopper conveyor belt to improve conveying performance and heat exchange efficiency.

[0053] Embodiment 2

[0054] Based on the above Embodiment 1, the shut-off door 201 includes:

[0055] The door body 2010 is slidably connected to the slag well 2, and an arc-shaped top surface 2011 is provided on the door body 2010;

[0056] The shut-off drive rack 2012 is embedded in the door body 2010;

[0057] The shut-off drive gear 2013 is rotatably connected in the first installation cavity 2014 inside the door body 2010. A first drive member is provided on the shut-off drive gear 2013 for driving the shut-off drive gear 2013 to rotate. The shut-off drive gear 2013 meshes with the shut-off drive rack 2012;

[0058] The adjustment rotating shaft 2015 is rotatably connected in the first installation cavity 2014. An angle adjustment gear 2016 is fixedly connected to the adjustment rotating shaft 2015. A second drive member is provided on the adjustment rotating shaft 2015 for driving the adjustment rotating shaft 2015 to rotate;

[0059] The coking screening steel plate 2017 has one end hinged to the door body 2010, and the other end of the coking screening steel plate 2017 is hinged to an angle adjustment rack 2018. The angle adjustment rack 2018 is slidably connected inside the door body 2010, and the angle adjustment rack 2018 meshes with the angle adjustment gear 2016.

[0060] The working principle and beneficial effects of the above technical solution are as follows: The design of the arc-shaped top surface 2011 causes the slag to roll down along the arc-shaped top surface 2011 onto the hopper-type slag conveyor belt 202, preventing the slag from accumulating on the top surface of the door body 2010 and causing difficulties in opening and closing the door body 2010;

[0061] When adjusting the opening degree of the shut-off door 201, the first drive member drives the shut-off drive gear 2013 to rotate, and the shut-off drive gear 2013 drives the shut-off drive rack 2012 to slide, so that the two door bodies 2010 approach or move away from each other, thereby realizing the function of adjusting the opening degree of the shut-off door 201;

[0062] The slag is prone to coking at high temperatures to form coked slag blocks. The inclination angle of the coking screening steel plate 2017 can be adjusted to screen the size of the coked slag blocks passing through the shut-off door 201. If the diameter of the coked slag block is smaller than the minimum distance between the two coking screening steel plates 2017, the coked slag block falls onto the scale-hopper type slag conveyor belt 202. If the diameter of the coked slag block is larger than the minimum distance between the two coking screening steel plates 2017, the coked slag block gets stuck between the two coking screening steel plates 2017. Thus, the coking screening steel plate 2017 plays a screening role. The screening of the coked slag block specifications helps to prevent larger-sized slag blocks from falling onto the scale-hopper type slag conveyor belt 202 and deforming the scale-hopper type slag conveyor belt 202, and at the same time, prevents the subsequent larger-sized slag blocks from blocking the feed inlet of the slag crusher 3.

[0063] When adjusting the inclination angle of the coking screening steel plate 2017, the second driving member drives the adjusting rotating shaft 2015 to rotate, thereby driving the angle adjusting gear 2016 to rotate. The angle adjusting gear 2016 drives the angle adjusting rack 2018 to slide, and the sliding of the angle adjusting rack 2018 drives the coking screening steel plate 2017 to rotate around the door body 2010, thus playing a role in adjusting the inclination angle of the coking screening steel plate 2017.

[0064] Embodiment 3

[0065] Based on Embodiment 1 or 2, it further includes: a coking crushing assembly 204, and the coking crushing assembly 204 includes:

[0068] An actuating piston 2044, the actuating piston 2044 is slidably connected in the second installation cavity 2045 of the door body 2010. A second elastic member 2046 is fixedly connected between the actuating piston 2044 and the inner wall of the second installation cavity 2045. One end of the actuating piston 2044 located outside the door body 2010 is hingedly connected to an intermediate connecting rod 2047, and the other end of the intermediate connecting rod 2047 away from the actuating piston 2044 is hingedly connected to the rocking member 2042;

[0069] The push rod 2052 is fixedly connected to one end of the actuating piston 2044 away from the intermediate connecting rod 2047;

[0071] The coke lump crushing member 2050 includes any one of a coke lump crushing needle body or a coke lump crushing piece.

[0072] The working principle and beneficial effects of the above technical solution are as follows: When a relatively large-sized coked furnace slag block gets stuck between the two coking screening steel plates 2017, the coking crushing assembly 204 is activated. The third driving member drives the driving winding wheel 2041 to rotate. The rotation of the driving winding wheel 2041 drives the winding 2051 to pull the rocking member 2042 to rotate. The rotation of the rocking member 2042 drives the intermediate connecting rod 2047 to move. The movement of the intermediate connecting rod 2047 drives the actuating piston 2044 to slide. The sliding of the actuating piston 2044 drives the push rod 2052 to move left and right. The left and right movement of the push rod 2052 drives the roller 2048 to rotate. The rotation of the roller 2048 drives the coke lump crushing member 2050 to rotate. During the rotation of the coke lump crushing member 2050, the electric telescopic member 205 can be telescoped, so that the furnace slag block is crushed into small pieces under the action of the coke lump crushing member 2050 and then falls on the scale bucket type furnace slag conveyor belt 202.

The rotation of the first sprocket 2020 drives the transmission chain 2023 to transmit, so that the entire conveyor belt is driven. During the conveying process of the conveyor belt, slag continuously falls on the scale buckets 2022 and is conveyed to the slag crusher 3 along with the scale buckets 2022.

A gate push rod 3022 is fixedly connected to the second slider 3021. The second gate 3005 is rotatably connected to the crusher housing 300. One end of the gate push rod 3022 away from the second slider 3021 is used to cooperate with the second gate 3005. A third buffer elastic member 3027 is fixedly connected between the upper surface of the second gate 3005 and the inner wall of the crushing cavity 3000;

[0094] A first pulley 3023 and a second pulley 3024. The first pulley 3023 is coaxially and rotationally connected to the intermediate turntable 3012 in the drive cavity 3001, and the second crushing member 3003 is coaxially and rotationally connected to the second pulley 3024 on the crusher housing 300. The first pulley 3023 and the second pulley 3024 are connected by a power transmission belt 3025;

[0095] The first crushing member 3002 is provided with a broken-line crushing section 3026 for crushing slag blocks;

[0096] The second crushing member 3003 is a crushing roller, and the two crushing rollers cooperate with each other to crush the slag blocks;

[0097] The first gate 3004 is a rectangular plate;

[0098] The second gate 3005 is a trapezoidal plate.

[0099] The working principle and beneficial effects of the above technical solution are as follows: During operation, the fifth driving member drives the short rod 3008 to slide along the guide groove 3007. Assuming that the two short rods 3008 move away from each other, at this time, the short rod 3008 drives the first connecting rod 3009 to move, the first connecting rod 3009 drives the intermediate turntable 3012 to rotate, the rotation of the intermediate turntable 3012 drives the third connecting rod 3013 to move, the movement of the third connecting rod 3013 drives the first slider 3011 to move away from the axis of the crusher housing 300, the movement of the first slider 3011 drives the T-shaped push rod 3015 to move away from the axis of the crusher housing 300, so that the pushing roller 3016 moves towards one end away from the rolling groove, so that the first gate 3004 moves away from the axis of the crusher housing 300 under the action of the first buffer elastic member 3019. At this time, the first gate 3004 is in an open state. At the same time, due to the action of the first buffer elastic member 3019, the rotating connecting rod 3017 is driven to rotate, and the rotation of the rotating connecting rod 3017 drives the crushing member connecting rod 3018 to move towards the axis of the crusher housing 300, so that the two first crushing members 3002 approach each other, and the slag blocks between the two first crushing members 3002 are crushed under the action of the two first crushing members 3002, and then fall to the second crushing member 3003 through the first gate 3004;

[0100] During the rotation of the intermediate turntable 3012, the first pulley 3023 is driven to rotate. The rotation of the first pulley 3023 drives the power transmission belt 3025 to transmit power. The transmission of the power transmission belt 3025 drives the second pulley 3024 to rotate. The rotation of the second pulley 3024 drives the second crushing member 3003 to rotate, so that the slag blocks crushed by the first crushing member 3002 fall between the two second crushing members 3003 and are crushed again;

[0101] Meanwhile, the middle turntable 3012 rotates to drive the fourth connecting rod 3014 to move, so that the second slider 3021 moves upward along the guide frame 3020, and thus the gate push rod 3022 moves away from the second gate 3005, and the second gate 3005 closes under the action of the third buffer elastic member 3027;

[0102] That is, when the short rod 3008 moves away from the axis of the crusher housing 300, the first gate 3004 opens, the second gate 3005 closes, and the first crushing member 3002 and the second crushing member 3003 crush the slag blocks simultaneously. Similarly, when the short rod 3008 moves closer to the axis of the crusher housing 300, the first gate 3004 closes, the second gate 3005 opens, and the first crushing member 3002 stops working. At this time, the crushed slag blocks are poured out. The different opening and closing states of the first gate 3004 and the second gate 3005 at the same moment ensure that the slag crusher 3 only performs one batch of crushing in a certain period, avoiding blockage of the slag crusher 3 due to excessive feeding. At the same time, the first crushing member 3002 uses extrusion crushing, and the second crushing member 3003 uses stirring crushing. Extrusion crushing can crush larger slag blocks, while the second crushing member 3003 is used to crush smaller slag blocks, and the division of labor improves the crushing efficiency of the slag crusher 3.
