Description

Technical Field

[0001] The utility model belongs to the field of garbage incineration treatment and relates to a material pushing device for a domestic garbage incinerator. Background Art

[0002] A waste incinerator is generally composed of a feeding system, an incineration system, a combustion air system, and an ash and slag discharge system. The feeding system includes a feeding hopper and a dropping chute, a pushing device, and a feeding platform. The pushing device is an important component of the incinerator. It receives the garbage falling from the feeding chute and effectively pushes it to the front grate for drying and combustion, which is directly related to the uniform feeding of the garbage and the stable operation of the incinerator. The pushing device must ensure that the garbage falling from the feeding chute does not slide directly onto the front grate, and realize effective quantitative feeding according to the garbage combustion requirements. At the same time, it must also be able to meet the high-temperature operating environment in front of the platform due to its connection with the furnace, ensuring long-term stable feeding operation, and also meet the various needs of the feeding process, so the requirements for the pushing device are relatively high.

[0003] However, the pusher device in the prior art only adopts a simple box structure that reciprocates in a straight line, and the box surface and the front pusher baffle are both made of ordinary steel plates, and the feeding platform is short and has a small stroke. The feeding platform is a platform for installing the pusher device and connecting the incinerator. After the domestic waste incinerator is shut down, the garbage on the feeding platform cannot be completely pushed into the grate of the incinerator for incineration, and is then retained on the feeding platform, resulting in the need for manual entry into the incinerator to clean up the unburned garbage on the feeding platform after the shutdown. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a material pushing device for a domestic waste incinerator to solve the problems raised in the background technology.

[0009] Furthermore, the fixing member is connected to the lower part of the material dropping chute in the domestic waste incinerator.

[0010] Furthermore, the double-layer trolley frame is arranged on a feeding platform in a domestic waste incinerator, and running wheels and blocking wheels are arranged at the bottom of the upper trolley frame.

[0011] Furthermore, a hydraulic cylinder connecting seat for connecting a hydraulic cylinder is provided at one end of the lower trolley frame close to the upper trolley frame, and a push plate is detachably connected to one end of the lower trolley frame away from the upper trolley frame.

[0034] Preferably, downwardly protruding unloading plate positioning blocks 12 are provided on both sides of the unloading plate 4, and trolley frame positioning blocks 14 cooperating with the unloading plate positioning blocks 12 are provided on both sides of the upper trolley frame 10, and the trolley frame positioning blocks 14 are located on the side of the unloading plate positioning blocks 12 away from the lower trolley frame 8, so as to realize the limiting of the unloading plate and the trolley frame when they move relative to each other.

[0040] The working principle of the pusher device for the domestic waste incinerator is as follows:

[0041] In normal operation, the pusher device as a whole (the unloading plate is connected to the double-layer trolley frame) performs reciprocating motion to perform the feeding operation;

[0042] When it is necessary to shut down the furnace or overhaul the hydraulic cylinder online, the pushing device will be retreated to its position. At this time, all the garbage on the top of the pushing device will be pushed into the front of the pushing device and the feeding platform 17, and the connection between the unloading plate 4 and the upper trolley frame 10 will be released. The pushing device advances to the specified position (the position of the fixing member 1) (for example, 800 mm forward), and the unloading plate 4 is connected and fixed by the fixing member 1. After the fixing is completed, the double-layer trolley frame reciprocates between retreating to its position and advancing to the specified position under the push of the hydraulic cylinder. At this time, while the garbage on the front of the trolley (the lower trolley frame 8) is pushed off by the vertical section of the unloading plate 4, part of the garbage on the feeding platform 17 is pushed into the grate for combustion. After multiple movements, the double-layer trolley frame is advanced to the specified position again, the connection between the fixing member 1 and the unloading plate 4 is released, and the unloading plate 4 is reconnected to the upper trolley frame 10. Finally, all the garbage on the feeding platform 17 is pushed into the grate for combustion through the reciprocating movement of the pushing device.

[0043] Preferably, when the amount of garbage pushed is reduced, the connection between the unloading plate 4 and the upper trolley frame 10 and the fixing part 1 is released at the same time. At this time, the unloading plate 4 can make reciprocating motion under the action of external force, and can be used as a pushing device alone during the operation of the incinerator. In this state, the rear hydraulic cylinder can be inspected, replaced, etc., thereby avoiding the risk of stopping the incineration line due to problems with the hydraulic components.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
