Description

Technical Field

[0001] The present invention relates to the field of incinerators, and particularly to a pusher mechanism for an incinerator. Background Art

[0002] Currently, in the field of production work, it is very common to use incinerators for material incineration. When the incinerator is working, it is necessary to feed materials. At present, for material feeding, it is generally manual feeding. However, manual feeding is prone to safety accidents during work, and during feeding, due to the high heat of the incinerator, it is very easy to roast and burn the feeder, affecting the physical health of the feeder. In addition, ordinary pusher devices cannot control the pusher volume during work, and it is very easy to have too many materials in the incinerator, affecting the incineration effect. Therefore, it is particularly important to solve the problems of easy safety hazards and easy material blockage in the incinerator feeding work.

[0003] Generally, the pusher mechanism for an incinerator in the prior art has only one feeding method. When the feeding mechanism is damaged, it must be immediately shut down for repair, affecting work efficiency. For example, the authorized announcement number CN205820396U discloses a weighing and metering feeding device, which specifically includes a material conveying device, a weighing module device, and a hopper device. The material conveying device directly conveys the material to the hopper device. In the case where the material conveying device cannot work, the whole machine cannot work normally. The application publication number CN 111102580 A discloses a feeding system for a rotary kiln hazardous waste incineration device, which specifically includes a feeding conveyor, a weighing hopper, a first-stage flap valve, a sealed chamber, a second-stage flap valve, and an inclined chute, and only discloses one feeding method of directly conveying the material from the feeding conveyor to the weighing hopper. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides a pusher mechanism for an incinerator that can avoid material blockage and has an auxiliary feeding system.

[0005] In order to achieve the above object, the present invention is realized through the following technical solutions:

[0006] The present invention is a pusher mechanism for an incinerator, which includes a weighing hopper and a pusher. A gate valve, an intermediate material pipe, and a flap valve are provided at the lower end of the weighing hopper. A feeding pipe is provided at the lower end of the flap valve. The feeding pipe is connected to the pusher housing. The lower end of the feeding pipe is communicated with the pusher. The gate valve is communicated with the feeding platform of the auxiliary feeding system. The auxiliary feeding system includes a weighable roller conveyor, a hoist, a feeding platform, and a hydraulic station providing power. An auxiliary feeding pusher mechanism is provided on the hoist. The front end of the pusher housing is connected to the kiln body through an inclined chute. An air-cooled sleeve is provided at the front end of the pusher housing.

[0007] A further improvement of the present invention lies in that a dust discharge pipe is provided on the pusher housing.

[0008] A further improvement of the present invention lies in that: several cold air inlets are provided on the air-cooling jacket.

[0009] A further improvement of the present invention lies in that: the pusher includes a pusher housing and a push head driven by a pusher oil cylinder to push materials. The push head and the pusher oil cylinder are located inside the pusher housing, and the pusher housing is supported by a support frame and a support platform.

[0010] A further improvement of the present invention lies in that: a pressure wheel in contact with the upper surface of the push head is provided on the pusher housing, and rollers are provided on both the side surface and the lower surface of the push head.

[0011] A further improvement of the present invention lies in that: the auxiliary feeding pusher mechanism includes a first horizontal pusher mechanism, a second horizontal pusher mechanism, and a first sealing valve and a second sealing valve that cooperate with the first horizontal pusher mechanism and the second horizontal pusher mechanism.

[0012] The beneficial effects of the present invention are as follows: The present invention is provided with an auxiliary feeding system. When an obstacle occurs in the main feeding system, the whole machine can continue to operate, effectively reducing the maintenance cost. The present invention pushes the materials through the push head. The two side surfaces and the lower surface of the push head are in sliding contact with the pusher housing through rollers. While ensuring the sealing performance, the push head can pass smoothly, realizing the shoveling action and effectively avoiding material blockage. Description of the Drawings

Detailed implementation mode

[0020] To deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. These embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0021] As Figures 1-6 shown, the present invention is a pusher mechanism for an incinerator, including a weighing hopper 1 and a pusher 6. A gate valve 2, an intermediate material pipe 3 and a flap valve 4 are arranged at the lower end of the weighing hopper 1. A feeding pipe 5 is arranged at the lower end of the flap valve 4. The feeding pipe 5 is connected to the pusher housing of the pusher 6 and communicates with the pusher 6 at the lower end of the feeding pipe 5. The gate valve 2 communicates with the feeding platform 11 of the auxiliary feeding system. The auxiliary feeding system includes a weighable roller conveyor 13, a hoist 10, a feeding platform 11 and a hydraulic station 12 providing power. A safety valve is arranged on the roller conveyor 13. After the material weighed by the roller conveyor 13 reaches the set weight, the safety valve opens, and the material is conveyed to the platform of the hoist 10 through the roller conveyor 13. A photoelectric switch for sensing the material is arranged on the platform of the hoist. After the photoelectric switch senses the material, the hoist 10 conveys the material to the feeding platform. An auxiliary feeding pusher mechanism is arranged on the hoist 10. The front end of the pusher housing is connected to the kiln body through an inclined chute, and an air-cooling jacket 14 is arranged at the front end of the pusher housing. Several cold air inlets are arranged on the air-cooling jacket 14, and an air outlet is arranged at the lower end of the air-cooling jacket 14. Cold air enters the air-cooling jacket 14 from the cold air inlets to cool the pusher housing, so that the pusher housing does not operate at a high temperature, and the service life of the equipment is improved.

[0022] An ash discharge pipe 8 is arranged on the pusher housing supported by a support platform 7. The pusher 6 includes a pusher housing and a pusher head 19 driven by a pusher oil cylinder. The pusher head 19 and the pusher oil cylinder are inside the pusher housing, and the pusher housing is supported by a support frame 9. A pressure wheel 20 in contact with the upper surface of the pusher head 19 is arranged on the pusher housing, and rollers 21 are arranged on the side and lower surface of the pusher head 19, so that while ensuring the sealing performance, the pusher head 19 can pass smoothly. The pusher housing is welded by corrosion-resistant and temperature-resistant plates, and is arranged at a certain angle with the horizontal plane during installation. Its length meets the requirement of penetrating deep into the kiln to avoid the phenomenon of solid waste return and liquid backflow.

[0023] The auxiliary feeding pusher mechanism includes a first horizontal pusher mechanism 15, a second horizontal pusher mechanism 16, and a first sealing valve 17 and a second sealing valve 18 cooperating with the first horizontal pusher mechanism 15 and the second horizontal pusher mechanism 16. The first horizontal pusher mechanism 15 includes a first horizontal pusher oil cylinder and a push plate, and the second horizontal pusher mechanism 16 includes a second horizontal pusher oil cylinder and a push plate.

[0024] Working principle: The material is placed on the roller conveyor 13. Press the start button, and the roller conveyor 13 starts to convey the material to the front of the safety valve and pauses for weighing. After the system collects the weighing data, the safety valve opens, and the roller machine on the elevator platform starts to convey the material to the elevator roller platform. There is a photoelectric switch on the platform. After detecting the arrival of the material, the safety valve closes, and the elevator roller platform stops conveying. The elevator 10 starts to lift. After lifting to the specified height, the first sealing valve 17 of the elevator 10 opens, and the first horizontal pusher oil cylinder of the elevator 10 starts to push the material into the sealed bin composed of the first sealing valve 17 and the second sealing valve 18 of the elevator 10. After pushing, the first horizontal pusher oil cylinder retracts to the starting point. After giving a signal, the first sealing valve 17 of the elevator 10 closes. After closing, a signal is given, and the feeding platform 11 descends to the origin. The second sealing valve 18 opens, and the second horizontal pusher oil cylinder pushes the material. After the pushing is completed, it returns to the origin, and the second sealing valve 18 closes. The pusher 6 pushes the material into the kiln. One auxiliary feeding process is completed.

[0025] The main feeding system and the auxiliary feeding system of the present invention cannot work simultaneously. Through the setting of the auxiliary feeding system, it can effectively prevent the situation that the main feeding system needs to stop due to a failure.
