Description

TECHNICAL FIELD

[0001] The utility model relates to incinerator technical field, concretely relates to a kind of incinerator pusher pusher trolley leachate rapid flow guide device. BACKGROUND

[0002] At present, the feeding system of garbage incinerator used in garbage incineration power plant basically includes three parts: feeding hopper, pusher trolley and pusher platform;A group of several parallel pusher trolleys are arranged on the pusher platform, the pusher trolley is connected with the hydraulic cylinder through the hydraulic push rod, and the pusher trolley advances or retreats on the pusher platform under the drive of the hydraulic system, and then the garbage on the pusher platform is sent into the grate of furnace chamber for combustion.

[0003] However, due to the large proportion of kitchen garbage in garbage, the water content of garbage is high, and the leachate in garbage enters the incinerator, which not only affects the calorific value of garbage incinerator, but also corrodes the grate, reducing the service life of garbage incinerator. CONTENT OF THE INVENTION

[0004] In view of the above technical problems, the utility model provides a kind of incinerator pusher pusher trolley leachate rapid flow guide device.

[0005] The technical scheme of the utility model is as follows: a kind of incinerator pusher pusher trolley leachate rapid flow guide device, including pusher and the flow guide groove assembly, leachate collecting hopper and flow guide pipe arranged on the pusher;The pusher includes pusher platform, guide rail arranged on the upper end surface of the pusher platform, pusher trolley slidingly connected to the guide rail and hydraulic oil cylinder arranged at the front end of the pusher platform and providing power for the pusher trolley;The pusher platform is a hollow frame structure, and a plurality of liquid leakage grooves are arranged on the upper end surface of the pusher platform;The output end of the hydraulic oil cylinder is connected with the hydraulic push rod connected with the pusher trolley;

[0006] The flow guide groove assembly is provided with two, and the two flow guide groove assemblies are arranged on the two sides inside the pusher platform respectively, and the flow guide groove assembly is composed of two flow guide inclined chutes arranged at the front and rear ends inside the pusher platform respectively;

[0007] The leachate collecting hopper is arranged on the lower bottom surface of the pusher platform and located between the two flow guide inclined chutes;

[0008] The flow guide pipe is provided with a plurality of flow guide pipes, each flow guide pipe is arranged horizontally at the rear end inside the pusher platform, and each flow guide pipe is in communication with the inside of the leachate collecting hopper.

[0009] Further, a plurality of cleaning blocks are arranged on the lower bottom of the pusher trolley, and each cleaning block is slidingly connected to each liquid leakage groove one by one;

[0010] Description: The pushing block moves on the pushing platform, and the cleaning block can clean the garbage pieces at the opening of the leakage groove.

[0011] Further, a plurality of V-shaped intercepting grooves are arranged in parallel on the upper end surface of the pushing platform and located at the rear end of the flow guide pipe, a collecting groove connected with each V-shaped intercepting groove is arranged in the pushing platform, and a flow collecting pipe connected with the leachate collecting hopper is arranged on the collecting groove.

[0012] Description: The garbage leachate flows to the rear end of the pushing platform under the pushing action of the pushing block, enters the V-shaped intercepting groove, and then enters the collecting groove, the flow collecting pipe and the leachate collecting hopper in sequence, which is beneficial to improve the flow guiding effect of the device.

[0013] Further, the pushing platform is arranged in an inclined manner, and the front end of the pushing platform is higher than the rear end.

[0014] Description: By arranging the pushing platform in an inclined manner, the flow speed of the garbage leachate is improved, and thus the working efficiency of the device is improved.

[0015] Further, a blocking filter screen is arranged above the flow guide groove assembly on the upper end surface of the pushing platform.

[0016] Description: By arranging the blocking filter screen above the flow guide groove assembly, the garbage can be prevented from entering the leachate collecting hopper.

[0017] The working principle of the utility model is as follows:

[0018] In use, the hydraulic pushing rod is driven by the hydraulic oil cylinder, the pushing block moves back and forth along the guide rail under the pushing action of the hydraulic pushing rod, and the garbage is pushed from the storage pit to the hearth for combustion; during the movement of the pushing block, the leachate in the garbage flows into the leachate collecting hopper through the leakage groove; meanwhile, the leachate flowing to the two sides of the pushing platform enters the leachate collecting hopper under the action of the flow guiding chute; and the leachate flowing down at the guide rail enters the leachate collecting hopper under the action of the flow guide pipe.

[0019] Compared with the prior art, the utility model has the following advantages:

[0020] (1) The leachate discharge efficiency is improved, and the risk of blockage is reduced.

[0021] Quick separation of liquid and slag: a larger leakage gap is reserved between the splicing plate of the pushing block and the guide rail, so that the leachate can be quickly discharged during the pushing of the garbage, and due to the limitation of the gap width, larger slag pieces are blocked at the front end of the pushing platform, so that the slag is prevented from mixing into the leachate system to cause pipeline blockage.

[0022] The flow guide groove assembly and the flow guide pipe direct the flow: the flow guide groove assembly on both sides of the pushing platform and the flow guide pipe under the sliding rail guide the leachate to the leachate collection bucket, preventing the leachate from flowing on the surface of the equipment and reducing corrosion or scaling caused by the retention of leachate;

[0023] (2) Protect the equipment and prolong its service life;

[0024] The leachate is usually highly acidic, high in salt content, and corrosive. By quickly discharging it, the leachate can be prevented from coming into long-term contact with the metal parts of the pusher, reducing the corrosion rate;

[0025] (3) Reduce the mechanical failure rate;

[0026] The slag is isolated in the pushing path, reducing the risk of the slag entering the guide rail gap and causing the pushing plate to jam or the rail to wear, ensuring smooth operation of the pusher;

[0027] (4) Optimize the combustion conditions and improve the incineration efficiency;

[0028] Maintain the cleanliness of the dry section of the garbage: the rectangular flow guide pipe at the bottom of the guide rail directs the leachate directly to the collection system, preventing the liquid from flowing into the dry section of the garbage. After the water content of the dry section of the garbage is reduced, it is easier to burn completely, reducing the heat consumed by water evaporation and improving the stability of the furnace temperature;

[0029] Improve the air permeability of the garbage: after the leachate is quickly discharged, the porosity of the garbage layer increases, oxygen permeation is more uniform, combustion completeness is promoted, and unburned residues and pollutants are reduced;

[0030] (5) Fire and explosion prevention;

[0031] The leachate contains combustible organic matter. Timely discharge can reduce the risk of accumulation in high-temperature areas causing spontaneous combustion or explosion;

[0032] (6) Prolong the replacement cycle of parts;

[0033] The key components of the pusher, such as the guide rail and the sealing element, are less prone to corrosion and wear, extending their service life and reducing the cost of spare parts procurement and replacement;

[0034] (7) Energy saving and consumption reduction

[0035] The improved pushing device can quickly discharge the leachate, avoiding the difficulty of pushing or unstable combustion caused by excessive moisture in the garbage.

[0036] (8) Adapt to complex garbage characteristics;

[0037] For garbage with a high water content, the improved pusher can quickly discharge the leachate, avoiding the difficulty of pushing or unstable combustion caused by excessive moisture in the garbage. BRIEF DESCRIPTION OF DRAWINGS
