Description

Technical Field

[0001] The invention relates to the technical field of slag conveying, and in particular to a device and method for preventing incineration slag from being blocked. Background Art

[0002] Garbage-to-energy refers to a form of power generation that uses an incineration boiler to burn urban solid waste and then generates electricity through a steam turbine generator set. Due to the wide variety of materials in the garbage, the organic matter in the garbage will be completely oxidized to generate a large amount of heat energy. At the same time, inorganic substances in the garbage, such as metals and glass, will also be melted to form slag. The slag produced after incineration is powdered ash and may also be mixed with flaky or lumpy inorganic substances. These slags usually need to be transported using a conveying device and can be reused. Since the conveyor belt of the conveying device is often used in conjunction with a loader, the feeding end of the conveyor belt is often designed to be a conical hopper to facilitate higher feeding. However, the slag has different shapes, and too much material may be fed into the hopper at one time, which may cause the hopper to be blocked.

[0003] The patent application document with the publication number CN117002917A discloses a slag conveying device, including a chain bucket conveying component and a fine material collecting component, wherein the chain bucket conveying component includes a housing component, a transmission component, a direction changing component and a chain bucket component; the fine material collecting component includes a mounting component, a material guiding component and a material discharging component; when in use, the slag enters the device from the feed inlet and first falls into the material transporting chain bucket located above, the large pieces of slag are transported away by the material transporting chain bucket in the chain bucket component, and the powder and fine material fall from the screening holes on the material transporting chain bucket, and the powder and fine material after falling are blocked by the material guiding component, fall to both sides, avoid the material transporting chain bucket below, and then enter the material discharging component for discharge, while the slag is lifted by the material transporting chain bucket to a high place for discharge. The conveying device solves the technical problem of silo blockage by conveying the powder and slag separately, but the powder will block the screening holes when entering the screening holes, which may cause the slag to be mixed with powder, so that the silo will also be blocked, affecting the conveying of the slag. Summary of the invention

[0004] In view of this, the present invention provides an anti-blocking conveying device and method for incineration furnace slag, aiming to solve the technical problem of easy blockage in the hopper in the prior art.

[0005] In order to solve the above technical problems, on the one hand, the present invention provides an incineration furnace slag anti-blocking conveying device, comprising a hopper arranged above a conveyor belt, wherein a screening mechanism capable of screening powdery materials and blocky materials is arranged in the hopper, wherein the screening mechanism comprises a discharge port arranged in the hopper for the powdery materials to fall, a plurality of buffer discharge rods horizontally arranged at the upper end of the discharge port and slidably connected to the discharge port, a driving unit arranged at one end of the buffer discharge rod for driving the buffer discharge rod to move back and forth along the axial direction of the buffer discharge rod, and a discharge channel arranged at the other end of the buffer discharge rod for the blocky materials to fall;

[0006] The buffer discharge rod has an upper end surface, and a plurality of barbs are arranged on the upper end surface at intervals along the axial direction of the buffer discharge rod. The barb has a supporting surface perpendicular to the axial direction and an inclined surface connecting the supporting surface and the upper end surface, and the inclined surface is inclined toward a side away from the discharge channel, so that the barb pushes the block material to move toward a side close to the discharge channel and fall into the discharge channel.

[0007] By adopting the above technical solution, the material falls from the hopper into the conveyor belt for transportation, and the driving unit drives the buffer discharge rod to move back and forth. The material falling into the hopper is driven by the buffer discharge rod, the powder material falls into the discharge port, and the block material falls into the discharge channel under the push of the barb. They are all transported by the conveyor belt to achieve the separation of powder material and block material, and solve the technical problem that the powder material and block material are all accumulated in the hopper and the hopper is easy to be blocked. At the same time, the reciprocating buffer discharge rod drives the material to shake and reduce the accumulation of materials in the hopper. The inclined surface of the barb is inclined to the side away from the discharge channel, and the supporting surface of the barb pushes the block material to move unidirectionally toward the end close to the discharge channel, but cannot move in the opposite direction. In this way, the block material can be continuously pushed into the discharge channel.

[0008] Preferably, the driving unit is arranged on one end of the buffer discharge rod away from the discharge channel, and the driving unit includes a crank connecting rod mechanism that drives the buffer discharge rod to move and a driving motor that drives the crank connecting rod mechanism to move.

[0009] By adopting the above technical solution, the crank connecting rod mechanism is driven by the driving motor to move, thereby driving the buffer discharge rod to move back and forth, thereby reducing the accumulation of materials in the hopper, and at the same time, driving the barbs to push the block material to move in one direction.

[0010] Preferably, the discharge port is surrounded by two first side panels and two second side panels, the two first side panels are arranged opposite to each other and are fixed on the inner wall of the hopper, and there is a gap between the two second side panels and the hopper, and the two gaps are respectively used to place the driving unit and form the discharge channel, and the lower end of the second side panel is located in the discharge channel and is obliquely provided with a guide plate.

[0011] By adopting the above technical solution, the first side plate and the second side plate are arranged to form a discharge port, and the second side plate also provides support for the buffer discharge rod. The powdered material falls onto the conveyor belt through the discharge port to realize transportation; a discharge channel is formed between the second side plate and the inner wall of the hopper, and the block material enters the discharge channel under the push of the buffer discharge rod. The guide plate guides the block material in the discharge channel, so that the block material slowly falls onto the conveyor belt, reducing the impact on the conveyor belt. At the same time, the guide plate can also scrape the powdered material on the conveyor belt to reduce the scattering of the powdered material during transportation.

[0012] Preferably, a stirring mechanism capable of stirring the powdered material is provided below the discharge port, and the stirring mechanism comprises a floating side plate hinged to the lower end of the first side plate, a roller rotatably connected to the two second side plates, and a driving member driving the roller to rotate;

[0013] The roller is evenly provided with blades along the circumferential direction which can drive the floating side plate to deflect back and forth. The rotation of the blades and the deflection of the floating side plate can both drive the powdered material to turn over.

[0014] By adopting the above technical solution, the stirring mechanism can stir the powdered material so that the powdered material falls evenly onto the conveyor belt, which is convenient for evenly conveying the powdered material and reduces the accumulation of the powdered material in the discharge port. The driving member drives the roller to rotate, and the blades on the roller contact the floating side plate, driving the floating side plate to deflect and flip the powdered material. At the same time, the blades can also flip the powdered material, reducing the accumulation of the powdered material and facilitating evenly conveying the powdered material.

[0015] Preferably, the two first side plates are both obliquely fixed on the inner wall of the hopper, the floating side plate is in contact with the second side plate, two floating side plates and two rollers are provided, and the two rollers rotate in opposite directions so that one floating side plate is deflected under the push of the blades, and the other floating side plate is deflected in the same direction under the action of its own gravity.

[0016] By adopting the above technical solution, the inclined setting of the first side plate can reduce the impact of the powdered material on the conveying device, which is conducive to smooth material discharge. The rotation directions of the two rollers are opposite, so that one floating side plate is deflected under the push of the blade, and the other floating side plate is deflected in the same direction under the action of its own gravity. In this way, the distance between the two floating side plates can be kept consistent, the powdered material can be flipped, and the squeezing of the powdered material is reduced, which is conducive to the uniform falling of the powdered material.

[0017] Preferably, the stirring mechanism further comprises a telescopic assembly capable of driving the blades to extend and retract, the telescopic assembly comprising a hydraulic oil passageway opened in the roller along the axial direction, a connecting piece having one end fixedly connected to the blade and the other end slidably connected to the roller and capable of extending into the hydraulic oil passageway, and a guide unit arranged in the hydraulic oil passageway capable of causing a plurality of the connecting pieces to move synchronously;

[0018] The oil pressure in the hydraulic oil channel can drive the connecting member and the blade to move in a direction away from / close to the axis of the roller, so as to change the deflection angle of the floating side plate.

[0019] By adopting the above technical solution, hydraulic oil is introduced into the hydraulic oil channel, the oil pressure in the hydraulic oil channel increases, pushing the connecting piece to move in the direction away from the roller axis, so that the blades extend, which can increase the maximum angle of deflection of the floating side plate pushed by the blades. Conversely, the oil pressure in the hydraulic oil channel is reduced, the connecting piece moves in the direction close to the roller axis, so that the blades contract, which can reduce the maximum angle of deflection of the floating side plate pushed by the blades, so as to meet the matching of the amount of material loaded in the hopper at one time and the maximum angle of deflection of the floating side plate, reduce the blockage of the hopper, and reduce the extrusion of powdered materials.

[0020] Preferably, the guide unit includes a synchronization rod rotatably connected in the hydraulic oil channel, a plurality of synchronization wheels fixedly connected to the synchronization rod, a plurality of guide grooves provided on the synchronization wheels, and a guide member slidably connected in the guide groove and fixedly connected to the connecting member, wherein the guide member drives the connecting member to move along the guide groove.

[0021] By adopting the above technical solution, when the connecting parts move under the action of oil pressure, they are guided by the guide parts and the guide grooves, so that multiple connecting parts in different directions move simultaneously, and the moving distances are equal. The heights of the blades are adjusted to be equal, so that the deflection angles of the floating side plates are the same, thereby achieving uniform turning of the powdered materials.

[0022] Preferably, the screening mechanism further includes a dust removal component, which includes a dust removal channel communicated with the discharge port and the discharge channel and an exhaust fan arranged at the end of the dust removal channel to remove dust suspended in the hopper.

[0023] By adopting the above technical solution, the flying dust in the discharge port and the discharge channel is sucked away by the exhaust fan through the dust removal channel, thereby reducing the dust suspended in the air.

[0024] On the other hand, the present invention provides a method for conveying incineration slag, using the incineration slag anti-blocking conveying device, comprising the following steps:

[0025] Step 1: The driving unit drives the buffer discharge rod to move back and forth. The material falling into the hopper is driven by the buffer discharge rod, and the powdered material falls into the discharge port and is transported by the conveyor belt;

[0026] Step 2: The bulk material falls into the discharge channel under the push of the barbs and is transported by the conveyor belt.

[0027] By adopting the above technical scheme, the material falls from the hopper into the conveyor belt for transportation, and the driving unit drives the buffer discharge rod to move back and forth. The material falling into the hopper is driven by the buffer discharge rod, the powder material falls into the discharge port, and the block material falls into the discharge channel under the push of the barb. All of them are transported by the conveyor belt to achieve separation of powder material and block material, which solves the technical problem that powder material and block material are all accumulated in the hopper and the hopper is easy to be blocked.

[0028] The beneficial effects of the above technical solution of the present invention are as follows:

[0029] 1. The buffer discharge rod of the present invention moves back and forth, causing the material to shake and reducing the accumulation of the material in the hopper; at the same time, driven by the buffer discharge rod, the powdery material falls into the discharge port, and the block material falls into the discharge channel under the push of the barb, and both are transported by the conveyor belt to achieve separation of the powdery material and the block material, solving the technical problem that the powdery material and the block material are all accumulated in the hopper and the hopper is easily blocked.

[0030] 2. The guide plate guides the bulk materials in the discharge channel, allowing the bulk materials to slowly fall onto the conveyor belt, reducing the impact on the conveyor belt. At the same time, the guide plate can also flatten the powder materials on the conveyor belt, reducing the scattering of powder materials during transportation.

[0031] 3. The blades on the roller of the stirring mechanism contact the floating side plate, driving the floating side plate to deflect and flip the powdered material. At the same time, the blades can also flip the powdered material, reducing the accumulation of powdered material and facilitating the uniform transportation of powdered material.

[0032] 4. Hydraulic oil is introduced into the hydraulic oil channel of the stirring mechanism. The oil pressure drives the blades to move away from / close to the axis of the roller, thereby adjusting the deflection angle of the floating side plate to match the amount of material loaded in the hopper at one time with the limit angle of deflection of the floating side plate, reducing the blockage of the hopper and the extrusion of the powdered material.

DETAILED DESCRIPTION

[0041] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be combined with the embodiments of the present invention. Figure 1-Figure 7 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0042] Example

[0043] This embodiment provides an incineration slag anti-blocking conveying device, such as Figure 1 As shown, it includes a conveyor belt 1 and a hopper 2. The hopper 2 is installed above the conveyor belt 1, and the incineration slag falls from the hopper 2 into the conveyor belt 1 for transportation.

[0044] like Figure 2As shown, a screening mechanism 3 and a stirring mechanism 4 are provided in the hopper 2. The screening mechanism 3 can screen the powdery materials and blocky materials in the incineration slag, so that the powdery materials and blocky materials are transported separately, reducing the blockage of the hopper 2. The stirring mechanism 4 can turn over the powdery materials to reduce the blockage of the hopper 2 by the powdery materials.

[0045] like Figure 2 As shown, the screening mechanism 3 includes a feeding port 31 , a feeding channel 32 , a buffer feeding rod 33 , a driving unit 34 and a dust removal assembly 35 .

[0046] like Figure 2 and Figure 4 As shown, the discharge port 31 is surrounded by two first side plates 311 and two second side plates 312. The two first side plates 311 are arranged opposite to each other and are respectively fixed obliquely on the front and rear inner walls of the hopper 2. The two second side plates 312 are arranged in parallel left and right and are both vertically fixed on the front and rear inner walls of the hopper 2. The second side plates 312 provide support for the buffer discharge rod 33. There is a gap between the two second side plates 312 and the hopper 2. The two gaps are respectively used to place the drive unit 34 and form the discharge channel 32. The lower end of the second side plate 312 is located in the discharge channel 32 and is inclined downward from left to right with a guide plate 321.

[0047] like Figure 1 and Figure 4 As shown, the inclined setting of the first side plate 311 can reduce the impact of powdered materials on the conveying device, which is conducive to smooth material discharge. The powdered materials fall onto the conveyor belt 1 through the discharge port 31 to achieve transportation; a discharge channel 32 is formed between the second side plate 312 and the inner wall of the hopper 2, and the block materials enter the discharge channel 32 under the push of the buffer discharge rod 33. The guide plate 321 guides the block materials in the discharge channel 32, so that the block materials slowly fall onto the conveyor belt 1, reducing the impact on the conveyor belt 1. At the same time, the guide plate 321 can also flatten the powdered materials on the conveyor belt 1 to reduce the scattering of the powdered materials during transportation.

[0048] like Figure 4 As shown, the dust removal assembly 35 includes a dust removal channel 351 and an exhaust fan, which are used to remove the suspended dust in the hopper 2. Figure 4 The exhaust fan is not shown.

[0049] like Figure 2 and Figure 4 As shown, the dust removal channel 351 is formed by the gap between the first side plate 311, the second side plate 312 and the inner wall of the hopper 2, and a ventilation groove 352 connected to the dust removal channel 351 is provided on the second side plate 312 close to the discharge channel 32. The dust removal channel 351 is communicated with the discharge port 31 and the discharge channel 32, and an exhaust fan is connected to the end of the dust removal channel 351 to remove the dust suspended in the hopper 2.

[0050] like Figure 1 and Figure 2 As shown, a plurality of buffer discharge rods 33 are provided, and the axial direction of the buffer discharge rod 33 is parallel to the conveying direction of the conveyor belt 1, and the conveying direction of the conveyor belt 1 is the left-right direction. The buffer discharge rods 33 are arranged on the two second side plates 312 in a front-to-back direction, and the buffer discharge rods 33 are slidably connected to the second side plates 312. Figure 3 As shown, the buffer discharge rod 33 has an upper end surface 331, and a plurality of barbs 332 are arranged on the upper end surface 331 at intervals along the left-right direction. The barbs 332 have a supporting surface 332-1 and an inclined surface 332-2. The supporting surface 332-1 is perpendicular to the left-right direction, and the inclined surface 332-2 connects the supporting surface 332-1 and the upper end surface 331. The inclined surface 332-2 is free to tilt leftward and downward. The buffer discharge rod 33 moves back and forth along the left-right direction, and the supporting surface 332-1 of the barb 332 pushes the block material to move rightward, and is transported in sequence through the plurality of barbs 332. Since the right end of the barb 332 is higher, the barb 332 pushes the block material to move unidirectionally to the right, but cannot move to the left, until the block material is pushed into the discharge channel 32.

[0051] like Figure 1 As shown, the driving unit 34 is arranged on the end of the buffer discharge rod 33 away from the discharge channel 32. The driving unit 34 in this embodiment includes a crank connecting rod mechanism 341 for driving the buffer discharge rod 33 to move, and a driving motor 431 for driving the crank connecting rod mechanism 341 to move. The crank connecting rod mechanism 341 is a prior art and will not be described in detail. In other embodiments, the driving unit 34 may also be a hydraulic cylinder.

[0052] like Figure 1 and Figure 2 As shown, the driving unit 34 drives the buffer discharge rod 33 to move back and forth in the left and right directions. The materials falling into the hopper 2 are driven by the buffer discharge rod 33, the powdered materials fall into the discharge port 31, and the block materials fall into the discharge channel 32 under the push of the barbs 332. They are all transported by the conveyor belt 1 to achieve the separation of powdered materials and block materials, solving the technical problem that the powdered materials and block materials are all accumulated in the hopper 2 and the hopper 2 is easy to be blocked. At the same time, the reciprocating buffer discharge rod 33 drives the material to shake, reducing the accumulation of materials in the hopper 2.

[0053] like Figure 1 and Figure 5 As shown, the stirring mechanism 4 includes a floating side plate 41 , a roller 42 , a driving member 43 , and a telescopic assembly 44 .

[0054] like Figure 2 and Figure 5As shown, two floating side plates 41 and two rollers 42 are provided, and the floating side plates 41 can deflect to stir the powdery materials falling from the discharge port 31, so that the powdery materials fall evenly onto the conveyor belt 1, which is convenient for evenly conveying the powdery materials and reduces the accumulation of the powdery materials in the discharge port 31. The telescopic assembly 44 can change the limit angle of deflection of the floating side plates 41, which is beneficial to reduce the blockage of the hopper 2 by the powdery materials and also helps to reduce the extrusion of the powdery materials.

[0055] like Figure 5 As shown, the floating side panel 41 is arranged below the first side panel 311 and is hinged to the first side panel 311. The hinge axis is along the left-right direction. The floating side panel 41 can realize deflection in the front-back direction. The left and right ends of the floating side panel 41 are both in contact with the second side panel 312, thereby reducing the powdery material scattered from between the second side panel 312 and the floating side panel 41.

[0056] like Figure 5 and Figure 7 As shown, the roller 42 is rotatably connected to the left and right second side plates 312, the axis of the roller 42 extends in the left and right direction, and a plurality of limit grooves 422 are evenly distributed on the roller 42 in the circumferential direction, and blades 421 are installed in the limit grooves 422. The blades 421 can contact the floating side plates 41 during the rotation of the roller 42, thereby pushing the floating side plates 41 to reciprocate, and one floating side plate 41 is correspondingly provided with one roller 42. The rotation of the blades 421 and the deflection of the floating side plates 41 can both drive the powdered material to flip, thereby reducing the blockage of the discharge port 31.

[0057] like Figure 1 and Figure 5 As shown, the driving member 43 is arranged at the left end of the hopper 2, and includes a motor 431 and a transmission member 432. The motor 431 is a power source, and the two rollers 42 are connected to each other through the transmission member 432. The transmission member 432 in this embodiment is a gear. By setting externally meshing gears on the two rollers 42, the rotation directions of the two rollers 42 are opposite, so that one floating side plate 41 is deflected under the push of the blade 421, and the other floating side plate 41 is deflected in the same direction under the action of its own gravity. The blades 421 on the two rollers 42 push the corresponding floating side plates 41 to deflect alternately in turn, so that the distance between the two floating side plates 41 can be kept consistent, the powdered material can be turned over, and the squeezing of the powdered material can be reduced, which is conducive to the uniform falling of the powdered material. The schematic diagram of the two rollers 42 driving the two floating side plates 41 to deflect in the same direction is as shown in FIG. Figure 5 shown.

[0058] like Figure 6 As shown, the telescopic assembly 44 includes a hydraulic oil channel 441 , a connecting piece 442 and a guide unit 443 .

[0059] like Figure 6As shown, the hydraulic oil channel 441 is opened in the roller 42 and extends in the left-right direction. The hydraulic oil channel 441 is used to pass hydraulic oil to push the blade 421 to extend and retract by oil pressure. The right end of the hydraulic oil channel 441 is sealed, and the left end is provided with an oil filling port.

[0060] like Figure 5 and Figure 6 As shown, multiple connecting members 442 are provided. The connecting member 442 in this embodiment is a connecting rod. One end of the connecting member 442 is fixedly connected to the blade 421. Multiple connecting members 442 are fixedly connected to one blade 421. Multiple through holes are opened in the limiting groove 422 of the roller 42. The other end of the connecting member 442 passes through the through hole and can extend into the hydraulic oil channel 441. Hydraulic oil is introduced into the hydraulic oil channel 441, and the oil pressure in the hydraulic oil channel 441 increases, pushing the connecting piece 442 to move in the direction away from the axis of the roller 42, so that the blade 421 extends, which can increase the maximum angle of deflection of the floating side plate 41 pushed by the blade 421. Conversely, the oil pressure in the hydraulic oil channel 441 is reduced, and the connecting piece 442 moves in the direction close to the axis of the roller 42, so that the blade 421 contracts, which can reduce the maximum angle of deflection of the floating side plate 41 pushed by the blade 421, so as to meet the matching of the amount of material loaded in the hopper 2 at one time and the maximum angle of deflection of the floating side plate 41, thereby reducing the blockage of the hopper 2 and reducing the squeezing of the powdered material.

[0061] like Figure 6 and Figure 7 As shown, the guide unit 443 includes a synchronization rod 443-1, a synchronization wheel 443-2, a guide groove 443-3 and a guide member 443-4.

[0062] like Figure 6 and Figure 7 As shown, the axial direction of the synchronization rod 443-1 extends in the left-right direction. The synchronization rod 443-1 is installed in the hydraulic oil channel 441. The end of the hydraulic oil channel 441 away from the oil filling port is rotatably connected to a sealing block 443-5. The synchronization rod 443-1 is rotatably connected to the sealing block 443-5. The synchronization rod 443-1 provides support for the synchronization wheel 443-2.

[0063] like Figure 6 and Figure 7 As shown, the synchronous wheel 443-2 is fixedly mounted on the synchronous rod 443-1, the center of the synchronous wheel 443-2 is located on the axis of the synchronous rod 443-1, the number of the synchronous wheels 443-2 is consistent with the number of the connecting members 442 connected to a blade 421, and they rotate synchronously with the synchronous rod 443-1.

[0064] like Figure 6 and Figure 7As shown, the guide groove 443-3 is opened on the synchronous wheel 443-2, and the number of the guide grooves 443-3 opened on each synchronous wheel 443-2 is consistent with the number of blades 421 installed on each roller 42. The guide groove 443-3 is arranged in a strip shape, and multiple guide grooves 443-3 on the same synchronous wheel 443-2 are close to the center of the synchronous wheel 443-2.

[0065] like Figure 6 and Figure 7 As shown, the guide member 443-4 is fixedly connected to one end of the connecting member 442 away from the blade 421, and the guide member 443-4 and the connecting member 442 are perpendicular. The guide member 443-4 in this embodiment is a guide rod, and the guide member 443-4 is slidably set in the guide groove 443-3, which can drive the connecting member 442 and the blade 421 to move along the guide groove 443-3.

[0066] like Figure 5-Figure 7 As shown, when the oil pressure in the hydraulic oil channel 441 is stable, the position of the connecting member 442 remains unchanged, the position of the guide member 443-4 relative to the guide groove 443-3 is fixed, and the synchronous rod 443-1 and the synchronous wheel 443-2 rotate synchronously with the connecting member 442 and the roller 42. When the height of the blade 421 needs to be adjusted, the oil pressure in the hydraulic oil channel 441 is changed, and the connecting member 442 moves under the action of the oil pressure. At the same time, the synchronous rod 443-1 and the synchronous wheel 443-2 are deflected relative to the roller 42 by the guide of the guide member 443-4 and the guide groove 443-3, and multiple connecting members 442 in different directions move at the same time, and the moving distances are equal. The height of the blade 421 is adjusted to be equal, so that the deflection angle of the floating side plate 41 is the same, and the powder material is evenly turned over.

[0067] When the embodiment of the above-mentioned incineration slag conveying method of the present invention is used, Figure 1 and Figure 2 As shown, the incineration slag material falls into the hopper 2, the driving motor 431 drives the crank connecting rod mechanism 341 to move, the crank connecting rod mechanism 341 drives the buffer discharge rod 33 to move back and forth in the left and right directions, and the powdered material falls into the discharge port 31 and is transported by the conveyor belt 1; Figure 2 and Figure 3 As shown, the block material stays on the buffer discharge rod 33. As the buffer discharge rod 33 moves back and forth, the barb 332 pushes the block material to move rightward in one direction until the block material is pushed into the discharge channel 32. The guide plate 321 guides the block material and conveys it through the conveyor belt 1 to separate the powder material and the block material, so that the hopper 2 is not easily blocked. Figure 2 As shown, the exhaust fan removes the dust at the discharge port 31 and the discharge channel 32 through the dust removal channel 351; Figure 1 and Figure 5As shown, the driving member 43 drives the roller 42 to rotate, and the blade 421 on one roller 42 pushes a floating side plate 41 to deflect, and the other floating side plate 41 deflects in the same direction under the action of its own gravity. The blades 421 on the two rollers 42 push the corresponding floating side plates 41 to deflect alternately in turn, and the distance between the two floating side plates 41 remains consistent, which can flip the powdered material and reduce the squeezing of the powdered material, which is conducive to the uniform falling of the powdered material.

[0068] like Figure 2 and Figure 5 As shown, when the amount of material added to the hopper 2 changes, the limit angle of deflection of the floating side plate 41 is changed by adjusting the height of the blade 421 to reduce the blockage of the hopper 2 and reduce the extrusion of the powdered material. The specific method is as follows: Figure 5-Figure 7 As shown, hydraulic oil is introduced into the hydraulic oil channel 441, and the oil pressure in the hydraulic oil channel 441 increases, pushing the connecting member 442 to move away from the axis of the roller 42, so that the blade 421 extends, increasing the limit angle of the deflection of the floating side plate 41 pushed by the blade 421. On the contrary, the oil pressure in the hydraulic oil channel 441 is reduced, and the connecting member 442 moves toward the axis of the roller 42, so that the blade 421 contracts, and the limit angle of the deflection of the floating side plate 41 pushed by the blade 421 is reduced. When the connecting member 442 moves under the action of the oil pressure, the synchronous rod 443-1 and the synchronous wheel 443-2 are deflected relative to the roller 42 by the guiding action of the guide member 443-4 and the guide groove 443-3. Multiple connecting members 442 in different directions move simultaneously, and the moving distances are equal. The heights of the blades 421 are adjusted to be equal, so that the deflection angles of the floating side plate 41 are the same, and the powder material is evenly turned over.

[0069] A method for conveying incineration slag of the present invention, using the above-mentioned embodiment of the incineration slag anti-blocking conveying device, comprises the following steps:

[0070] Step 1: The incineration slag material falls into the hopper 2, the driving motor 431 drives the crank connecting rod mechanism 341 to move, the crank connecting rod mechanism 341 drives the buffer discharge rod 33 to move back and forth in the left and right directions, the powder material falls into the discharge port 31, the driving member 43 drives the roller 42 to rotate, the blade 421 on one roller 42 pushes a floating side plate 41 to deflect, and the other floating side plate 41 deflects in the same direction under the action of its own gravity, the blades 421 on the two rollers 42 push the corresponding floating side plates 41 to deflect alternately in turn, and the powder material falls on the conveyor belt 1 for transportation after being stirred;

[0071] Step 2: The block material remains on the buffer discharge rod 33. As the buffer discharge rod 33 reciprocates, the barb 332 pushes the block material to move to the right until the block material is pushed into the discharge channel 32. The guide plate 321 guides the block material and transports it through the conveyor belt 1.

[0072] Step 3: When the amount of material added to the hopper 2 increases, hydraulic oil is introduced into the hydraulic oil channel 441, the oil pressure in the hydraulic oil channel 441 increases, and the connecting member 442 is pushed to move in the direction away from the axis of the roller 42. Under the guidance of the guide member 443-4 and the guide groove 443-3, the synchronous rod 443-1 and the synchronous wheel 443-2 are deflected relative to the roller 42, and multiple connecting members 442 in different directions move at the same time, and the moving distances are equal, so that the extended heights of the blades 421 are equal, and the maximum angle of deflection of the floating side plate 41 pushed by the blades 421 is increased; conversely, when the amount of material added to the hopper 2 decreases, the oil pressure in the hydraulic oil channel 441 is reduced, and the connecting member 442 moves in the direction close to the axis of the roller 42. Under the guidance of the guide member 443-4 and the guide groove 443-3, the contracted heights of the blades 421 are equal, and the maximum angle of deflection of the floating side plate 41 pushed by the blades 421 is reduced.

[0073] In other embodiments of the incineration furnace slag anti-blocking conveying device of the present invention, the following replacement and deformation methods can be adopted:

[0074] 1. In other embodiments, the difference from the above embodiments is that the dust removal assembly 35 is omitted. When a dust reduction device is installed in the hopper 2, the dust removal assembly 35 may not be installed.

[0075] 2. In other embodiments, the difference from the above embodiment is that the stirring mechanism 4 is omitted. When the amount of incineration slag falling from the hopper 2 at one time is relatively small and the powder material is also relatively small, the powder material directly falls onto the conveyor belt 1 through the discharge port 31 and does not block the discharge port 31, the stirring mechanism 4 may not be installed.

[0076] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0077] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
