Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a sealing structure for a feed port of a garbage bin incinerator and a construction method thereof. Background Art

[0002] The goal of waste disposal is to render it harmless, recycle it, and reduce its volume. Waste disposal involves the prompt removal of waste, its harmless treatment, and its proper utilization. Currently, sanitary landfill, high-temperature composting, and incineration are widely used methods of waste disposal. Incineration is one of the primary methods of waste disposal.

[0003] At the same time, in order to incinerate the garbage, the garbage disposal agency will set up garbage incineration equipment and factory buildings in the designated site, and after the initial crushing of the garbage, transfer it through the feeding mechanism to the garbage incineration equipment in the factory for incineration.

[0004] During their research and improvement, the R&D personnel found that after the incineration equipment and the plant were connected, the feeding mechanism was directly connected to the garbage bin in the incineration plant. After the feeding mechanism was installed, there was a large gap between it and the garbage bin. If concrete was used to seal it directly, cracks would easily form in the concrete during use. The long-term accumulation of garbage in the garbage bin would produce a large amount of odorous gas. It was believed that there was a defect that the odorous gas in the garbage bin was easy to overflow. Summary of the Invention

[0005] In order to reduce the overflow of odorous gases in a garbage bin, the present application provides a sealing structure and construction method for a feed port of a garbage bin incinerator.

[0006] In the first aspect, the present application provides a garbage bin incinerator feed port sealing structure, which adopts the following technical solution: a garbage bin incinerator feed port sealing structure, comprising a feed hopper, a feeding pipe for conveying garbage, a garbage bin and an air-sealing mechanism for reducing the overflow of odorous gases in the garbage bin, a feed port being provided on the garbage bin, the feed hopper being located outside the garbage bin, one end of the feed hopper being fixedly connected to the feeding pipe, and the other end being inserted into the feed port and fixedly connected to the garbage bin; a sealing groove being provided on the outer wall of the garbage bin along the circumference of the feed port, an annular rib being fixed circumferentially on the feed hopper, the annular rib being inserted into the sealing groove, a grouting layer being laid on the garbage bin, and after the annular rib is inserted into the sealing groove, the grouting layer seals the sealing groove and the annular rib.

[0007] By adopting the above technical solution, when the feed hopper is inserted into the feed port and the annular rib is inserted into the sealing groove, the grouting layer seals the sealing groove, making it difficult for the grouting layer to crack. At the same time, since the connection is basically completely closed, the overflow of odorous gases in the garbage bin is reduced.

[0008] Optionally, the air-sealing mechanism includes an inverted bucket and an air-sealing sleeve. The inverted bucket is located inside the garbage bin and is fixedly connected to the feed hopper. The air-sealing sleeve circumferentially wraps the inverted bucket, and one end of the air-sealing sleeve abuts against the inner wall of the garbage bin where the feed port is located, and the other end is fixedly connected to the outer wall of the inverted bucket.

[0009] By adopting the above technical solution, the air-sealing mechanism can seal the feed port in the garbage bin, and cooperate with the sealing groove, annular ribs and grouting layer to enhance the effect of isolating the overflow of odorous gases in the garbage bin.

[0010] Optionally, an air-locking groove is opened inside the garbage bin, and the air-locking groove is arranged circumferentially along the inner wall of the air-locking groove where the feed port is located. The inverted bucket is connected to the feed hopper flange, and when the inverted bucket is installed, the air-locking sleeve is embedded in the air-locking groove.

[0011] By adopting the above technical solution, after the inverted bucket is installed, the air-sealing sleeve is embedded in the air-sealing groove, thereby improving the air-sealing mechanism's isolation effect on odorous gases in the garbage bin.

[0012] Optionally, a vibration mechanism is provided in the feed hopper, which includes a high-frequency vibrator, a vibration plate and several vibration springs. The vibration plate is circumferentially laid on the inner wall of the feed hopper. The vibration springs are all located between the vibration plate and the feed hopper, and one end of the vibration spring is fixedly connected to the feed hopper, and the other end is fixedly connected to the vibration plate. The high-frequency vibrator is fixed to the outer wall of the feed hopper, and its piston column is fixedly connected to the vibration plate after passing through the feed hopper.

[0013] By adopting the above technical solution, the vibration mechanism can vibrate the garbage passing through the feed hopper when the garbage is started by the feed hopper, so that the garbage is easily poured into the garbage bin.

[0014] Optionally, a limit plate is further provided inside the feed hopper, the limit plate is circumferentially fixed to the inner wall of the feed hopper, and the limit plate is located above the vibrating plate and covers the limit plate.

[0015] By adopting the above technical solution, the setting of the limit plate can limit the vibration range of the vibration plate. At the same time, since the limit plate is located above the vibration plate and covers the limit plate, it can prevent garbage from flowing into the gap between the vibration plate and the feed hopper.

[0016] Optionally, several support holes are opened on the outer wall of the garbage bin along the circumference of the sealing groove, and the support holes are distributed in an array along the circumference of the sealing groove. Several support mechanisms are also provided on the garbage bin, and the support mechanisms include support rods and support plates. The support rods correspond to the support holes one by one, and the support rods are inserted into the support holes. The support plates are fixed to the end face of the support rod away from the garbage bin, and the support plates are in contact with the outer wall of the feed hopper.

[0017] By adopting the above technical solution, the setting of the supporting mechanism can support the feed hopper and enhance the stability of the connection between the feed hopper and the garbage bin.

[0018] Optionally, an abutment groove is provided on the feed hopper, and the abutment groove is circumferentially arranged on the outer wall of the feed hopper. After the annular rib is embedded in the abutment groove, it is threadedly connected to the feed hopper through bolts.

[0019] By adopting the above technical solution, the annular ribs are detachably connected to the feed hopper, which facilitates the disassembly and replacement of the feed hopper.

[0020] Optionally, the grouting layer is filled in two steps, and the grouting layer is a CGM grouting material layer.

[0021] Optionally, a sealing rubber ring is fixed to the outer wall of the connection between the feed hopper and the upper feed pipe to prevent waste liquid from overflowing during garbage transportation.

After the grouting layer 14 initially fills the sealing groove 12, the annular rib 3 is inserted into the sealing bin close to the end face of the garbage bin 1. The grouting layer 14 fills the L-shaped opening of the annular rib 3 away from the side wall of the feed hopper 2 and the wall of the sealing groove 12 for the second time. After curing, the grouting layer 14 is fixedly connected to the sealing groove 12 and the annular rib 3 respectively. In this embodiment, the grouting layer 14 can be a CGM grouting material layer.

[0045] refer to Figure 2 and Figure 3 , the garbage bin 1 is also provided with several support holes 13. In this embodiment, only X support holes 13 are shown for illustration.
