Description

Technical Field

[0001] The utility model relates to the technical field of slag discharging equipment, in particular to a slag discharging device for preventing jamming of boiler auxiliaries. Background Technique

[0002] A boiler is an energy converter, which is a device that uses the heat energy released by fuel combustion or other heat energy to heat the working medium water or other fluids to a certain parameter. It is mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises. The boiler mainly operates by burning coal. After the coal blocks burn inside the boiler, a large amount of slag will be generated, and the discharge of slag requires the use of slag discharging equipment.

[0003] The existing slag discharging equipment mainly drives the spiral slag discharging rod to rotate through a motor, so as to push the slag entering at the slag inlet to the slag outlet, and then the slag is discharged through the slag outlet. Since the slag is mainly formed by the combustion of coal inside the combustion chamber, there is a large amount of coke in the slag and it forms lumps. These lumps are easy to get stuck inside the slag discharging equipment during the conveying process, resulting in the blockage of the slag discharging equipment and thus affecting the slag discharging efficiency. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing slag discharging device, the utility model provides a slag discharging device for preventing jamming of boiler auxiliaries, which has the advantages of being able to crush large-volume slag and preventing the internal blockage of the slag discharging device, and solves the technical problems such as the easy blockage caused by large-volume slag.

[0005] The utility model provides the following technical solutions: A slag discharging device for preventing jamming of boiler auxiliaries, including a conveying box, and further including:

[0006] A slag inlet, fixedly arranged on the upper left side of the outer surface of the conveying box, and a slag outlet is fixedly arranged on the lower right side of the outer surface of the conveying box. A flange is fixedly installed on the left end face of the conveying box;

[0007] A motor, fixedly installed in the middle of the left end face of the flange, and a spiral slag discharging rod is fixedly sleeved on the output end of the motor. The spiral slag discharging rod is located inside the conveying box.

[0008] Preferably, the spiral slag discharging rod includes:

[0009] A fixed rod, fixedly connected to the spiral end face of the spiral slag discharging rod directly below the slag inlet;

[0010] A connecting rope 1, fixedly connected to the fixed rod;

[0011] A counterweight, fixedly connected to the end of the connecting rope 1 away from the fixed rod.

[0012] Preferably, the spiral slag discharging rod further includes:

[0013] An elastic rod, fixedly connected to the spiral end face of the spiral slag discharging rod directly below the slag inlet and located outside the fixed rod;

[0014] A magnetic block, fixedly arranged inside the elastic rod.

[0015] Preferably, the inside of the slag inlet includes:

[0016] A mounting rod, fixedly connected to the side wall of the slag inlet;

[0017] A connecting rope II, fixedly connected to the bottom surface of the middle part of the mounting rod;

[0018] A magnetic ball, fixedly connected to one end of the connecting rope II far away from the mounting rod.

[0019] Preferably, the magnetism of the magnetic ball is opposite to that of the magnetic block. When the magnetic block rotates to the slag inlet, the magnetic block is within the magnetic field range of the magnetic ball.

[0020] Compared with the prior art, the present utility model has the following beneficial effects:

[0021] 1. By designing the fixed rod, connecting rope, counterweight, etc., when the slag enters the inside of the conveying box through the slag inlet, large pieces of slag will be caught by multiple fixed rods, and then the spiral slag discharging rod is used to drive the fixed rod to rotate, so that the counterweight on the fixed rod rotates following the transmission of the connecting rope I. When the slag caught by the fixed rod rotates to the lower side of the counterweight, the slag will be broken up by the counterweight to form small pieces of slag, reducing the probability of blockage of the slag discharging device.

[0022] 2. By designing the mounting rod, connecting rope II, magnetic ball, elastic rod, magnetic block, etc., when the elastic rod is driven by the spiral slag discharging rod to rotate to the slag inlet, the magnetic ball is used to adsorb the magnetic block, causing the elastic rod to deform. When the torque transmitted by the spiral slag discharging rod to the elastic rod is greater than the magnetic attraction force of the magnetic ball on the magnetic block, the elastic rod will be affected by its own elastic potential energy, prompting the magnetic block to leave the adsorption of the magnetic ball, resulting in the elastic potential energy of the elastic rod acting on the slag caught by the fixed rod. Since the main component of the slag is coke, the brittleness of the slag is relatively high. After the elastic potential energy of the elastic rod acts on the slag, the slag will be broken by the elastic rod, preventing blockage inside the slag discharging equipment due to large slag blocks and improving the slag discharging efficiency.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 - 5 , a slag discharge device for preventing jamming of boiler auxiliaries, including a conveying box 1. A slag inlet 2 is fixedly arranged on the upper left side of the outer surface of the conveying box 1 to facilitate the furnace slag to enter the conveying box 1. A slag outlet 3 is fixedly arranged on the lower right side of the outer surface of the conveying box 1 for discharging the furnace slag. A flange 4 is fixedly installed on the left end face of the conveying box 1. A motor 5 is fixedly installed in the middle of the left end face of the flange 4. A spiral slag discharge rod 6 is fixedly sleeved on the output end of the motor 5. The spiral slag discharge rod 6 is located inside the conveying box 1. By driving the spiral slag discharge rod 6 to rotate by the motor 5, and then using the spiral blades on the spiral slag discharge rod 6, the furnace slag inside the conveying box 1 is promoted to move towards the slag outlet 3 and finally discharged through the slag outlet 3.

[0031] Please refer to Figures 1 - 5 , a fixed rod 61 is fixedly welded on the spiral end face of the spiral slag discharge rod 6 directly below the slag inlet 2. Multiple fixed rods 61 are used to block large-volume furnace slag. A first connecting rope 62 is fixedly connected to the fixed rod 61. A counterweight 63 is fixedly connected to the end of the first connecting rope 62 away from the fixed rod 61. When the spiral slag discharge rod 6 rotates, the counterweight 63 is driven to swing by the first connecting rope 62, so that the swinging counterweight 63 impacts the furnace slag blocked on the fixed rod 61, promoting the fragmentation of the furnace slag.

[0032] Please refer to Figures 1 - 5, the spiral slag discharging rod 6 is located on the spiral end face directly below the slag inlet 2 and is fixedly welded with an elastic rod 64 outside the fixed rod 61. A magnet 65 is fixedly arranged inside the elastic rod 64, so that after the elastic rod 64 deforms, the elastic potential energy of the elastic rod 64 is used to break large-volume slag.

[0033] Please refer to Figures 1 - 5 , an installation rod 21 is fixedly welded on the side wall of the slag inlet 2. A second connecting rope 22 is fixedly connected to the bottom surface of the middle part of the installation rod 21. A magnetic ball 23 is fixedly connected to the end of the second connecting rope 22 away from the installation rod 21.

[0034] Please refer to Figures 1 - 5 , the magnetism of the magnetic ball 23 is opposite to that of the magnet 65. When the magnet 65 rotates to the slag inlet 2, the magnet 65 is within the magnetic field range of the magnetic ball 23, ensuring that when the elastic rod 64 is driven by the spiral slag discharging rod 6 to rotate to the magnetic ball 23, the magnetic attraction of the magnetic ball 23 to the magnet 65 is used to cause the elastic rod 64 to deform and store energy. And when the torque of the spiral slag discharging rod 6 driving the elastic rod 64 to rotate is greater than the magnetic attraction of the magnetic ball 23 to the magnet 65, the elastic rod 64 will release its elastic potential energy, thereby acting on the large-volume slag to break the large-volume slag and avoid blockage inside the conveying box 1 caused by the large-volume slag.

[0035] Working principle: When discharging slag, the slag is transported into the interior of the conveying box 1 through the slag inlet 2, and then the motor 5 is started. The motor 5 drives the spiral slag discharging rod 6 to rotate, and the rotating spiral slag discharging rod 6 is used to discharge the slag inside the conveying box 1 through the slag outlet 3. During this process, multiple fixed rods 61 are used to hold large pieces of slag, and then the spiral slag discharging rod 6 drives the fixed rods 61 to rotate, so that the counterweights 63 on the fixed rods 61 rotate following the transmission of the first connecting rope 62. When the slag held by the fixed rods 61 rotates to the lower side of the counterweights 63, the slag will be broken up by the counterweights 63 to form small pieces of slag, reducing the probability of blockage of the slag discharging device. Secondly, when the elastic rod 64 is driven by the spiral slag discharging rod 6 to rotate to the slag inlet 2, the magnetic ball 23 is used to adsorb the magnet 65, causing the elastic rod 64 to deform. When the torque transmitted by the spiral slag discharging rod 6 to the elastic rod 64 is greater than the magnetic attraction of the magnetic ball 23 to the magnet 65, the elastic rod 64 will be affected by its own elastic potential energy, causing the magnet 65 to leave the adsorption of the magnetic ball 23, and the elastic potential energy of the elastic rod 64 will act on the slag held by the fixed rod 61. Since the main component of the slag is coke, the slag has high brittleness. After the elastic potential energy of the elastic rod 64 acts on the slag, the slag will be broken by the elastic rod 64, preventing blockage inside the slag discharging equipment due to large slag blocks and improving the slag discharging efficiency.
