Technical Field

[0001] The utility model relates to the technical field of garbage incineration, in particular to a slag remover for a garbage incinerator with anti-blocking and water-saving functions. Background Art

[0002] In order to handle the increasing domestic garbage, garbage incineration has gradually become a common domestic garbage treatment method. By incinerating garbage as fuel for power generation, the garbage can be utilized to the greatest extent. During the daily operation of a garbage incineration power plant, it is necessary to treat the slag after incineration. The slag remover is installed below the slag dropping port at the tail of the grate, and is used for cooling and discharging the slag after garbage combustion, the ash leakage from the grate, and the sedimentation ash collected by the boiler ash hopper. The slag remover is cooled by industrial water. The water in the cavity can not only cool the slag after combustion in time, but also ensure that the furnace chamber is always isolated from the outside world, maintaining a negative pressure state in the furnace, and the steam generated during the slag cooling process does not spread outside the equipment.

[0003] At present, in order to ensure the sealing effect of the water seal, the water tank of the slag remover must ensure a certain overflow rate, resulting in a large amount of water resource waste. And because the existing water tank has a flat bottom structure, and the sealing water contains a large amount of sediment and combustion residues, it is easy to enter the water tank and deposit in the water tank, easily blocking the water outlet of the water tank and the water inlet of the slag remover, and it needs to be cleaned frequently, which not only affects the operation of the equipment, but also increases the labor cost, and consumes a lot of manpower and financial resources. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a slag remover for a garbage incinerator with anti-blocking and water-saving functions, which solves the problems of a large amount of overflow of the cooling water of the slag remover and the easy blockage of the water inlet of the slag remover and the water outlet of the water tank, which need to be cleaned regularly.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A slag remover for a garbage incinerator with anti-blocking and water-saving functions, including a slag remover body, the top of the slag remover body is provided with a slag inlet, the rear end is provided with a slag outlet, and a pusher head that can swing reciprocally to push the slag towards the slag outlet is arranged in the inner cavity of the slag remover body;

[0006] A water tank is arranged at the front end of the slag remover body, the bottom of the water tank slopes downward from front to back, the water outlet at the lower end of the water tank is communicated with the slag remover body, a rotatable water replenishing pipe is horizontally arranged in the water tank, a plurality of spray heads for spraying water towards the lower part of the bottom of the water tank are arranged on the water replenishing pipe, and a liquid level gauge is arranged on the water tank.

[0007] Further, both ends of the water replenishing pipe are fixedly connected to support rods that are rotatably connected to the inner wall of the water tank. One of the support rods at one end rotatably extends to the outside of the water tank, and a fixed disk is fixedly connected to the outer end. An outer edge of the fixed disk is fixedly connected to a connecting rod. A hydraulic cylinder is arranged on the surface of the water tank through a hinge seat. The other end of the hydraulic cylinder is hinged to the outer end of the connecting rod. The telescopic movement of the hydraulic cylinder drives the water replenishing pipe to swing.

[0008] Further, it further includes a water inlet pipe that extends into the water tank. The inner end of the water inlet pipe is communicated with a flexible hose, and the flexible hose is communicated with the water inlet end of the water replenishing pipe. A solenoid valve is arranged at the water inlet end of the water replenishing pipe.

[0009] Further, a rotating shaft is rotatably arranged in the inner cavity of the slag remover body. A connecting frame is fixedly connected to the surface of the rotating shaft.

Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-3 , the present invention provides a technical solution for an anti-blocking and water-saving slag remover for a waste incinerator, including a slag remover body 1. A slag inlet 2 is provided at the top of the slag remover body 1, and a slag outlet 3 is provided at the rear end. A pusher head 4 that can reciprocally swing to push slag towards the slag outlet 3 is provided in the inner cavity of the slag remover body 1.

[0018] The slag remover body 1 is installed below the slag dropping port at the tail of the grate, and is used for cooling and discharging the slag after garbage combustion, the ash leakage from the grate, and the sedimentation ash collected by the boiler ash hopper.

[0019] After the slag enters the slag remover body 1, it is mixed and cooled under the action of a large amount of cooling water. The pusher head 4 reciprocates back and forth in the inner cavity of the slag remover. The cooled slag slowly moves upward with the movement of the pusher head 4. After moving a certain distance and controlling water and dewatering, it is discharged from the slag remover and enters the subsequent treatment system.

[0020] A water tank 5 is provided at the front end of the slag remover body 1. The bottom of the water tank 5 slopes downward from front to back. The water outlet 12 at the lower end of the water tank 5 is communicated with the slag remover body 1. A rotatable water replenishing pipe 6 is horizontally arranged in the water tank 5. A plurality of spray heads 7 for spraying water to the lower part of the bottom of the water tank 5 are provided on the water replenishing pipe 6. A liquid level gauge 13 is provided on the water tank 5.

[0021] The water tank 5 is communicated with the water inlet of the slag remover body 1 through the water outlet 12, so that the two form a communicating vessel. The highest liquid level in the water tank 5 should be higher than the normal liquid level in the inner cavity of the slag remover body 1 to ensure that there is sufficient cooling water in the inner cavity of the slag remover body 1.

[0022] The bottom of the water tank 5 is inclined, so that sediment, sundries, etc. in the water tank 5 will naturally flow downward along the bottom of the water tank 5 and enter the inner cavity of the slag removal machine body 1, and be discharged together with the slag, avoiding a large accumulation in the water tank 5. On the one hand, it can reduce the accumulation of sediment and impurities and lower the cleaning frequency. On the other hand, it can reduce the repeated scouring and wear of the sediment on the equipment and extend the service life of the equipment.

[0023] A sewage outlet is still provided at the bottom of the water tank 5 for necessary cleaning work.

[0024] The water supply pipe 6 is used for supplying water to the water tank 5 on the one hand. On the other hand, the water supply pipe 6 swings at the Figure 1 shown perspective, so that the nozzle 7 can swing within a range of 90° in the vertical and horizontal rearward directions (the swing angle can also be less than 90°, such as 45°, 60°, etc., which should be specifically set according to the usage situation), and repeatedly flush the connection between the water tank 5 and the slag removal machine body 1, washing the remaining sediment and sundries at the bottom into the slag removal machine body 1, keeping the connection between the water tank 5 and the slag removal machine body 1 unblocked and preventing blockage and inability to intake water.

[0025] It also includes a water inlet pipe 14. The water inlet pipe 14 extends into the water tank 5. The inner end of the water inlet pipe 14 is connected with a hose 15. The hose 15 is connected with the water inlet end of the water supply pipe 6. A solenoid valve 16 is provided at the water inlet end of the water supply pipe 6.

[0026] The outer end of the water inlet pipe 14 is connected with a water supply device, is connected with the water supply pipe 6 through the hose 15, and controls the on-off of the water inlet pipeline by opening and closing the solenoid valve 16 to control water supply.

[0027] The hose 15 has a redundant length, so that during the rotation and swing of the water supply pipe 6, the hose 15 always has enough length to maintain the connection, giving the water supply pipe 6 sufficient freedom.

[0028] The water level height is monitored and controlled through the solenoid valve 16, the liquid level gauge 13 on the surface of the water tank 5 and an external control device. When the pusher 4 pushes the slag for slag discharge, a part of the cooling water will be carried away. At this time, the water in the water tank 5 will flow into the slag removal machine body 1, resulting in a decrease in the water level. The external control device controls the solenoid valve 16 to open for water supply according to the water level height detected by the liquid level gauge 13 being lower than the standard height. At the same time, the water supply pipe 6 starts to rotate and swing for cleaning. When the water level is replenished to the normal operating water level, the solenoid valve 16 is closed to stop water supply.

[0029] The water level can be automatically controlled, and the water seal tightness effect can be maintained without the water tank 5 maintaining overflow, reducing water consumption and waste, reducing production water use, and lowering costs.

[0030] Both ends of the water replenishing pipe 6 are fixedly connected with support rods 8 rotatably connected to the inner wall of the water tank 5. One of the support rods 8 rotatably extends to the outside of the water tank 5, and the outer end is fixedly connected with a fixed disk 9. The outer edge of the fixed disk 9 is fixedly connected with a connecting rod 10. A hydraulic cylinder 11 is arranged on the surface of the water tank 5 through a hinge seat. The other end of the hydraulic cylinder 11 is hinged to the outer end of the connecting rod 10. The telescopic movement of the hydraulic cylinder 11 drives the water replenishing pipe 6 to swing.

[0031] The support rod 8 supports the water replenishing pipe 6 and enables it to rotate and swing. The hydraulic cylinder 11, the connecting rod 10, and the fixed disk 9 form a swing arm mechanism. Through the repeated telescopic movement of the hydraulic cylinder 11, the fixed disk 9 is driven to rotate forward and backward within a certain angle, thereby driving the water replenishing pipe 6 to rotate forward and backward, repeatedly changing the angle of the nozzle 7 for flushing.

[0032] The installation angle, specifications, etc. of the hydraulic cylinder 11 and the connecting rod 10 are adjusted according to the actual situation.

[0033] A rotating shaft 17 is rotatably arranged in the inner cavity of the slag remover body 1. A connecting frame 18 is fixedly connected to the surface of the rotating shaft 17. A hydraulic push rod 19 is hinged in the inner cavity of the slag remover body 1. The other end of the hydraulic push rod 19 is hinged to the connecting frame 18. The end of the push head 4 is fixedly connected to the connecting frame 18.

[0034] The rotating shaft 17, the connecting frame 18, and the hydraulic push rod 19 also form a set of swing arm mechanisms. All are provided with hydraulic power by hydraulic devices. The telescopic movement of the hydraulic push rod 19 drives the connecting frame 18 to rotate and swing around the rotating shaft 17 to control the reciprocating swing of the push head 4 for pushing slag and discharging slag.

[0035] The rotating shaft 17, the connecting frame 18, the hydraulic push rod 19, etc. are located above the highest water level line in the inner cavity of the slag remover body 1.

[0036] Positioning mechanisms for restricting the stroke of the push head 4 are arranged on both sides inside the slag remover body 1.

[0037] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
