Description

Technical Field

[0001] The utility model belongs to the technical field of incinerators, and particularly relates to a leachate recovery device for a garbage incinerator. Background Art

[0002] Before the garbage incinerator equipment incinerates garbage, the garbage will be placed in a garbage pool for several days for pretreatment; during the pretreatment process, harmful gases and harmful liquids will be generated. The harmful gases are filtered and treated by an exhaust device, and the harmful leachate liquid enters the sewage discharge pipe and is then treated in a sewage treatment plant for filtration. In the actual process, not all the leachate liquid will enter the drainage pipe, and a considerable part of it will adhere to the surface of the garbage and is not treated before entering the garbage incineration device. For example, during the process of incinerating garbage in a grate incinerator, the leachate flows from the garbage to the pusher car and the moving area of the pusher car, and is pushed by the pusher car into the garbage incinerator grate or the driving component area of the pusher car. The leachate has certain corrosiveness and will damage the internal moving components such as shafts and cylinders and the components that are not corrosion-resistant, ultimately resulting in the corrosion of the components, the failure of the incinerator parts or the driving components, etc. This causes losses to the manufacturers using the incinerator equipment, bringing economic losses and time waste.

[0028] The present utility model will be further clarified below in conjunction with specific embodiments. The embodiments are implemented on the premise of the technical solution of the present utility model. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model.

[0029] Embodiment 1

[0030] As Figure 1 、 Figure 2 And Figure 3 shown, a leachate recovery device for a waste incinerator is used for the leachate recovery of the waste incinerator. In this embodiment, the waste incinerator is a grate-type incinerator, including a furnace body 92 and a feed hopper 93. The furnace body 92 is arranged on a support 91. The leachate recovery device of this embodiment is arranged on the support 91. The leachate recovery device includes a working plate 1, a pusher trolley 2, a driving component 3, a liquid collection tank 5 and an outer housing 6. The working plate 1 is arranged below the feed hopper 93 and supported by the support 91. The working plate 1 is at the same height as the waste inlet of the furnace body 92. The waste to be treated enters the waste channel from the feed hopper 93 and then falls onto the working plate 1. The working plate 1 is a rectangular plate. The pusher trolley 2 moves back and forth on the working plate 1. The driving component 3 is connected to the pusher trolley 2 for pushing the pusher trolley 2. In this embodiment, the driving component 3 is a push rod, and the push rod can be an electric, pneumatic or hydraulic push rod. The piston rod of the push rod drives the pusher trolley 2 to move back and forth.

[0031] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 And Figure 7 shown, the working plate 1 is a rectangular plate. The working plate 1 includes a material receiving plate 11 and a leakage plate 12. The material receiving plate 11 and the leakage plate 12 are integrally connected. The material receiving plate 11 is located directly below the feed hopper 93 and at one end of the working plate 1 close to the furnace body 92. The leakage plate 12 is located at the end of the working plate 1 away from the furnace body 92. A plurality of first leakage holes 121 are provided on the leakage plate 12. In this embodiment, the first leakage holes 121 are rectangular holes and a plurality of first leakage holes 121 are arranged in an array on the leakage plate 12.

[0032] AsFigure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in Figure 5 , Figure 6 , Figure 7 , the pusher trolley 2 includes a top plate 21 and two support foot plates 22. The top plate 21 is arranged parallel to the working plate 1. A second leakage hole 211 is provided on the top plate 21. The two support foot plates 22 are connected to the front and rear ends of the top plate 21 and extend towards the working plate 1. A gap is left between the lower ends of the support foot plates 22 and the working plate 1. A reinforcing rib is also connected below the top plate 21 to strengthen the strength of the vehicle body. A plurality of rollers 221 are connected to the support foot plate 22 connected to the rear end of the top plate 21, and the piston rod of the driving assembly 3 is connected to this support foot plate 22. A scraper 4 is connected to the support foot plate 22 connected to the front end of the top plate 21 (near one end of the receiving plate 11). The scraper 4 is connected to the outer side of the support foot plate 22. The lower end of the scraper 4 contacts the upper surface of the working plate 1. When the driving assembly 3 pushes the pusher trolley 2 to move back and forth, the lower end of the scraper 4 slides on the upper surface of the working plate 1. The driving assembly 3 drives the pusher trolley 2 to move back and forth on the receiving plate 11 and the leakage plate 12. When the garbage entering from above the feed hopper 93 falls onto the receiving plate 11 of the working plate 1 through the garbage channel, the driving assembly 3 is started to push the pusher trolley 2 forward. The support foot plate 22 and the scraper 4 at the front end of the pusher trolley 2 push the garbage in front into the furnace body 92. At this time, there is still a large amount of garbage above the top plate 21. The leachate of the garbage flows through the second leakage hole 211 to the upper surface of the receiving plate 11. The driving assembly 3 drives the pusher trolley 2 backward. Since the lower end of the scraper 4 contacts the upper surface of the receiving plate 11, the scraper 4 scrapes the leachate on the upper surface of the receiving plate 11 backward to the upper surface of the leakage plate 12. The garbage in the upper channel continues to fall in front of the pusher trolley 2, waiting for the next pusher operation of the pusher trolley 2.

[0033] As Figure 2 and Figure 3 shown, a liquid collecting tank 5 is connected below the leakage plate 12. The liquid collecting tank 5 is communicated with the first leakage hole 121. The leachate on the leakage plate 12 flows into the liquid collecting tank 5 through the first leakage hole 121 and is thus collected. A liquid discharge pipe 51 is connected to the bottom of the liquid collecting tank 5 for discharging the leachate.

[0034] As Figure 3 , Figure 4 and Figure 7As shown in the figure, the outer cover 6 is connected to the working plate 1 and is in correspondence with the leakage plate 12 in position. The outer cover 6 covers the leakage plate 12, so that a receiving cavity is formed between the outer cover 6 and the leakage plate 12. There is a notch at the front end of the outer cover 6 that communicates with the receiving cavity. The driving assembly 3 is connected to the rear side of the outer cover 6. The driving assembly 3 pushes the material pushing trolley 2 to move back and forth. When the material pushing trolley 2 moves back and forth, it moves into or out of the receiving cavity from the notch. When the material pushing trolley 2 moves onto the leakage plate 12, it is located in the receiving cavity. When the material pushing trolley 2 moves out of the receiving cavity from the notch, it is located on the material receiving plate 11. The outer cover 6 is provided with a water inlet pipe 61, and the water inlet pipe 61 communicates with the receiving cavity. Through the water inlet pipe 61, external cleaning water can be introduced into the receiving cavity. Since there are second leakage holes 211 on the top plate 21 and first leakage holes 121 on the leakage plate 12, the space in the receiving cavity communicates with the liquid collecting tank 5. The water inlet pipe 61 communicates with the liquid collecting tank 5 through the second leakage holes 211 and the first leakage holes 121. After the external cleaning water cleans the top plate 21 and the leakage plate 12 in the receiving cavity, the sewage flows into the liquid collecting tank 5 and is collected. At the corresponding position between the edge of the notch of the outer cover 6 and the top plate 21, there is a sealing strip 62. The sealing strip 62 is made of rubber material. The sealing strip 62 does not affect the movement of the material pushing trolley 2 and can block excessive water from flowing out of the receiving cavity when cleaning the material pushing trolley 2.

[0035] Embodiment 2

[0036] The difference from Embodiment 1 is that a plurality of rollers 221 are also connected to the supporting foot plate 22 near one end of the material receiving plate 11. The rollers 221 are connected to the inner side of the supporting foot plate 22. When the material pushing trolley 2 moves back and forth, it is supported by the plurality of front and rear rollers 221. And the gap between the lower end of the supporting foot plate 22 and the upper surface of the working plate 1 in this embodiment is narrower than that in Embodiment 1. The scraping plate 4 in this embodiment is hinged to the inner side of the supporting foot plate 22. The scraping plate 4 is connected to the inner side of the supporting foot plate 22 through a hinge shaft. The scraping plate 4 can only rotate towards the inner side of the supporting foot plate 22. When the scraping plate 4 rotates towards the outer side of the supporting foot plate 22, it will be blocked by the supporting foot plate 22. A soft scraping strip 41 is connected to the lower end of the scraping plate 4. The soft scraping strip 41 is made of rubber material. The lower end of the soft scraping strip 41 contacts the upper surface of the working plate 1. When the material pushing trolley 2 moves forward, the front supporting foot plate 22 pushes the garbage. Since the gap between the front supporting foot plate 22 and the upper surface of the working plate 1 is small, the material pushing work can be completed. When the material pushing trolley 2 moves backward, the scraping plate 4 and the soft scraping strip 41 move backward to scrape the leachate on the material receiving plate 11 onto the leakage plate 12, so that the leachate flows into the liquid collecting tank 5 and is collected.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
