Abstract
Description
Technical Field
[0001] The invention relates to the technical field of slag removal, and in particular to a full-automatic dry slag removal extrusion device. Background Art
[0002] The existing slag discharge system has a furnace bottom slag discharge device between the slag pit and the air-cooled steel belt slag conveyor. The device is mainly used to intercept large coke blocks larger than 200mm, and has the functions of pre-cooling and pre-crushing. It also has the function of shutting off the door. When the subsequent system needs maintenance, it is closed to temporarily store the slag in the slag pit.
[0003] When the coal quality changes, resulting in a large amount of boiler slag or serious coking, a large amount of coke will accumulate on the furnace bottom slag discharge device. Improper combustion adjustment and long-term high load increase the probability of large coke falling. When the boiler is blown, the observation window is seriously ash-filled and it is impossible to observe the internal coke falling. In addition, the slag in the slag pit is of different sizes when discharged, making it difficult to control the discharge amount, which can easily lead to the slag being discharged and accumulated on the steel belt.

The gravity measuring machine monitors the weight change of the hopper in real time, and combined with the collection function of the limiting bag for coal slag, it can more accurately reflect the accumulation state of coal slag, providing a reliable basis for the decision-making of the control system. By precisely controlling the slag discharging speed and the size of the discharge port, the phenomenon of the steel belt machine slipping caused by excessive accumulation of coal slag can be avoided. At the same time, the need for manual monitoring of the monitor is changed to automatic infrared temperature monitoring, eliminating the situation where it is impossible to observe through the observation window due to fly ash when the boiler is sootblown and hot coke drops in the slag well, or accidental coking and dropping, resulting in untimely extrusion and coke stacking.

[0037] Embodiment 1
[0038] Refer to Figures 1 - 3 , which is the first embodiment of the present invention. This embodiment provides a fully automatic dry slag extrusion device, including that the coal slag generated by the combustion of the boiler 101 falls into the slag well 102 in a mechanically sealed manner. An observation window 104 is provided on the side wall of the slag well 102, and the accumulation situation and state of the ash slag are monitored by the first camera 103.
[0039] Specifically, the transportation component 100 includes a boiler 101. The bottom end of the boiler 101 is installed with a slag well 102 through mechanical sealing. An observation window 104 for the first camera 103 to monitor the ash slag situation is provided on the side wall of the slag well 102, and a transfer member 105 is installed at the bottom end of the slag well 102.
[0040] Furthermore, a steel belt machine 105a for transporting coal slag is installed at the bottom end of the transfer member 105. A cooling air inlet door 105b is provided at the top end of the end of the steel belt machine 105a, and a cooling air inlet 105c is provided on the side wall of the cooling air inlet door 105b.
[0041] Furthermore, the transfer member 105 further includes an accident sprinkler 105d provided at the top end of the steel belt machine 105a. A buffer slag hopper 105f matching the bucket elevator 105e is provided at the bottom end of the end of the steel belt machine 105a, and a primary slag crusher 105g is provided inside the buffer slag hopper 105f.
[0042] Furthermore, the transfer member 105 further includes a slag bin 105h provided on the side wall of the bucket elevator 105e. A vibrator 105i is provided at the material guiding port of the inner wall of the slag bin 105h. A feeder 105j is provided at the bottom end of the slag bin 105h. A pressure relief valve 105k is provided at the top end of the slag bin 105h, and a dust collector 105l is provided on the side wall of the pressure relief valve 105k.
[0043] Furthermore, the transfer member 105 further includes a second camera 105m provided at the bottom end of the steel belt machine 105a. Three sets of telescopic cylinders 105n are provided inside each slag well 102, and the output end of the telescopic cylinder 105n is connected to an extrusion head 105p.
[0044] Operation process: When the cinder accumulates to a certain amount, the transfer component 105 starts to work. The transfer component 105 mainly consists of a steel belt conveyor 105a, a cooling air inlet 105b, an accident sprinkler 105d, a buffer cinder hopper 105f, a primary cinder crusher 105g, a bucket elevator 105e, a cinder bin 105h, etc. The steel belt conveyor 105a is located below the cinder well 102, and its surface is used to carry and transport cinders. A cooling air inlet 105b is provided at the top end of the steel belt conveyor 105a, and cooling air is introduced through the cooling air inlet 105c to cool the cinders and prevent the high-temperature cinders from damaging the equipment and the steel belt. During the cinder transfer process, if abnormal situations occur, such as overheating or blockage of the cinders, the accident sprinkler 105d will start to spray and cool or wash the cinders to ensure the stable operation of the system. After the preliminary transportation by the steel belt conveyor 105a, the cinders are transferred to the buffer cinder hopper 105f. Inside the buffer cinder hopper 105f, the primary cinder crusher 105g performs preliminary crushing on the cinders for subsequent processing. The crushed cinders are lifted to the cinder bin 105h by the bucket elevator 105e. The cinder bin 105h is used to store cinders, and a vibrator 105i is provided at the material guiding port on the inner wall to prevent the cinders from blocking inside the cinder bin. A feeder 105j is provided at the bottom end of the cinder bin 105h to control the discharge amount of the cinders. A pressure relief valve 105k and a dust collector 105l are provided at the top end of the cinder bin 105h to adjust the pressure inside the cinder bin and remove dust, ensuring the safety and cleanliness of the working environment. During the cinder transfer and processing process, the second camera 105m monitors the cinder situation on the steel belt conveyor 105a in real time to ensure the smooth transfer of the cinders. At the same time, three sets of telescopic cylinders 105n are provided inside each cinder well 102, and their output ends are connected to the extrusion head 105p. When there is a large accumulation of cinders or large cinder blocks, the telescopic cylinder 105n drives the extrusion head 105p to extrude and crush the cinders to improve the transfer efficiency and processing effect.
[0045] Embodiment 2
[0046] Refer to Figures 3 - 6 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the working principle of the slag discharge assembly 200 mainly operates around the limiting member 203 in the cinder well 102 to achieve intelligent adjustment of the discharge port of the cinder well 102, thereby optimizing the ash slag discharge process.
[0047] Specifically, the slag discharging assembly 200 includes a hydraulic cylinder 201 arranged on the side wall of the slag well 102. The middle part of the slag well 102 in the vertical direction is circularly arranged. A limiting member 203 is arranged inside the slag well 102, and a measuring member 204 is arranged at the top of the inside of the slag well 102 and the limiting member 203. The hydraulic cylinder 201 is installed on the side wall of the slag well 102, and its telescopic movement is used to drive the action of the limiting member 203. The middle part of the slag well 102 in the vertical direction is designed to be circular to adapt to the circular structure of the limiting member 203.
[0048] Further, the limiting member 203 includes a sliding plate 203a arranged inside the slag well 102. A limiting ring 203b is installed at the end of the sliding plate 203a. The diameter of the top end of the limiting ring 203b is larger than that of the bottom end, and the diameter of the limiting ring 203b in the vertical direction becomes smaller downward. Driven by the hydraulic cylinder 201, the sliding plate 203a can move up and down inside the slag well 102. The movement of the sliding plate 203a drives the limiting ring 203b to move up and down. Due to the special design of the limiting ring 203b (the diameter of the top end is larger than that of the bottom end, and the diameter in the vertical direction becomes smaller downward), the size of the discharge port of the slag well 102 can be changed when it moves.
[0049] Further, the limiting member 203 further includes a first hinge plate 203c arranged inside the limiting ring 203b. A second hinge plate 203d is hingedly installed at the bottom end of the first hinge plate 203c. The first hinge plate 203c and the second hinge plate 203d are both circularly arranged around the midpoint of the limiting ring 203b to form a circle with a gap. The bottom side wall of the second hinge plate 203d is connected to the slag well 102. The first hinge plate 203c and the second hinge plate 203d are circularly arranged around the midpoint of the limiting ring 203b, and they are hinged by a telescopic ring 203e to form a circular structure with a gap. This structure can expand or contract as the limiting ring 203b moves, thereby further adjusting the size of the discharge port of the slag well 102.
[0050] Further, the limiting member 203 further includes a telescopic ring 203e arranged between the first hinge plate 203c and the second hinge plate 203d. The first hinge plate 203c and the second hinge plate 203d are hinged by the telescopic ring 203e, and an extension plate 203f is installed on the outer wall of the top end of the first hinge plate 203c. The measuring member 204 is used to monitor the situation of the coal slag inside the slag well 102 in real time, such as the accumulation height and density of the coal slag. When the coal slag accumulates to a certain extent, the measuring member 204 will send a signal to the control system, and the control system adjusts the telescopic amount of the hydraulic cylinder 201 according to the received signal, thereby driving the sliding plate 203a and the limiting ring 203b to move up and down, and further changing the size of the discharge port.
[0051] The remaining structures are the same as those in Embodiment 1.
[0052] Operation process: When the hydraulic cylinder 201 receives a control signal, it drives the sliding plate 203a to move up and down on the side wall of the slag well 102. The movement of the sliding plate 203a drives the limiting ring 203b to move up and down, thereby changing the angle between the first hinge plate 203c and the second hinge plate 203d. Since the first hinge plate 203c and the second hinge plate 203d are connected by the telescopic ring 203e, the change in the angle between them causes the telescopic ring 203e to expand and contract, thereby changing the diameter of the entire limiting member 203. When the diameter of the limiting member 203 increases, the area of the discharge port also increases correspondingly, which is suitable for discharging larger ash residues; when the diameter of the limiting member 203 decreases, the area of the discharge port also decreases correspondingly, which is suitable for discharging smaller ash residues or for fine adjustment. The extension plate 203f may be used to prevent ash residues from scattering or splashing during the discharge process, ensuring the safety and cleanliness of the discharge process. The measuring member 204 can monitor the situation of the ash residues in the slag well 102 in real time and transmit the data to the control system. The control system analyzes and judges according to the received data, and then issues a corresponding control signal to the hydraulic cylinder 201 to achieve intelligent control of the slag discharge assembly 200.
[0053] Embodiment 3
[0054] Referring to Figures 4 - 5 , this is the third embodiment of the present invention. The difference between this embodiment and the above embodiments is that the measuring member 204 can monitor the accumulation situation of the coal slag in the slag well 102 in real time and accurately, providing reliable data support for the automatic adjustment of the slag discharge assembly 200.
[0055] Specifically, the measuring member 204 includes a hopper 204a arranged at the top of the first hinge plate 203c. A gravity measuring machine 204b is installed on the outer wall of the hopper 204a. The hopper 204a and the first hinge plate 203c are hinged by steel balls 204c. The hopper 204a is arranged at the top of the first hinge plate 203c and is used to collect the coal slag falling from the slag well 102. A gravity measuring machine 204b is installed on the outer wall of the hopper 204a, which can measure the weight of the coal slag in the hopper 204a in real time and transmit the measurement data to the control system.
[0056] Further, the measuring member 204 further includes a limiting bag 204d disposed inside the circles of the first hinge plate 203c and the second hinge plate 203d. The limiting bag 204d is limited by the circle formed by the first hinge plate 203c and the second hinge plate 203d, and a moving space is directly formed between the hopper 204a and the slag well 102. A moving space is formed between the hopper 204a and the slag well 102, and this space allows the hopper 204a to make adaptive adjustments during the coal slag accumulation process. When the coal slag accumulates to a certain extent, the weight of the hopper 204a will increase, and the gravity measuring machine 204b will detect this change and transmit the data to the control system. The control system judges the accumulation situation of the coal slag according to the received data, and adjusts the telescopic amount of the hydraulic cylinder 201 accordingly, so as to change the size of the discharge port of the slag discharging assembly 200, and realize the efficient discharge of the coal slag.
[0057] The remaining structures are the same as those in Embodiment 2.
[0058] Operation process: First, the cinder generated by the boiler 101 directly falls into the cinder well 102. Then, the first camera 103, which has an infrared temperature detection function, can monitor the cinder falling situation on the cinder well 102 through the observation window 104, and then automatically control the extrusion head extrusion and the air damper opening according to the cinder falling situation. If it is high-temperature hot cinder or larger ash cinder, after detection by the first camera 103, the opening of the cooling air inlet damper 105b is appropriately increased to increase the cooling air, and the telescopic cylinder 105n is automatically started to drive the extrusion head 105p to move to extrude the larger ash cinder. When the system pressure is monitored to increase during the extrusion process, it immediately exits and alarms to prevent the hot cinder from hardening and damaging the extrusion head 105p or extruding into the boiler and falling equipment. If it is loose ash cinder, after detection by the first camera 103, only a single extrusion head 105p is started to advance and retreat to push out the ash cinder. At the same time, the second camera 105m monitors the ash accumulation situation on the steel belt conveyor 105a to prevent excessive accumulation and cause the steel belt to jam and slip. And according to the ash accumulation situation, the standby bucket elevator 105e is started at the same time. When the larger ash cinder falls into the cinder well 102, the instantaneous impact force of the ash cinder will cause the limit bag 204d to deform and impact the hopper 204a. When the gravity measuring machine 204b on the hopper 204a detects the gravity, its data will be compared and verified with the data measured on the first camera 103. If the data coincides and the cinder is large, the hydraulic cylinder 201 is immediately started. The hydraulic cylinder 201 drives the sliding plate 203a to move in the inner wall of the discharge port of the cinder well 102. The moving sliding plate 203a drives the limit ring 203b to move upward. The upward moving limit ring 203b abuts against the bottom end of the extension plate 203f to drive the first hinged plate 203c to move upward. Thus, the moving first hinged plate 203c will deflect to drive the expansion ring 203e to expand and enlarge the discharge port, and when the cinder is small, the discharge port is reduced, so as to effectively control the discharge amount and reduce the phenomenon of ash cinder accumulation and slipping on the steel belt conveyor 105a. The limit bag 204d is made of metal material and can resist high temperature. The impact force generated by the smaller ash cinder will not cause its deformation through the limit bag 204d, so that the ash cinder can be directly discharged.
