Description

Technical Field

[0001] This utility model relates to the field of waste heat boilers, and in particular to an energy-saving and environmentally friendly waste heat boiler flue cleaning device. Background Technology

[0002] Waste heat boilers, as an energy-saving and emission-reduction device, are an indispensable key link in the smelting process. Their main function is to cool down the flue gas generated in the furnace during the smelting process, and at the same time, use the heat released during the cooling process to generate steam, which is then used in other production processes.

[0003] The stability of waste heat boiler operation is directly related to the operating rate of the smelting process and the reliable operation of subsequent related systems. The smelting process at the front end of the waste heat boiler generates a large amount of smoke and dust, which is transported and exchanged with water for heat. In related technologies, the waste heat boiler includes a boiler body, a heating surface installed in the boiler body, and a flue that is connected to the inside of the boiler body. After the smoke and dust exchange heat with water, the smoke and dust are discharged through the flue.

[0004] When smoke and dust are discharged through the flue, they tend to adhere to the inside of the flue. Over time, this can clog the flue and increase energy consumption. Therefore, an energy-saving and environmentally friendly waste heat boiler flue cleaning device is proposed. Utility Model Content

[0033] Compared with the prior art, the beneficial effects of this utility model are:

[0034] In operation, the energy-saving and environmentally friendly waste heat boiler flue cleaning equipment uses a first motor to drive a lead screw, which automatically adjusts the height of the lifting plate, thereby adjusting the height of the cleaning scraper. A second motor drives a drive gear, which in turn drives a ring-shaped driven gear to rotate a ring-shaped mounting plate. This allows the cleaning scraper to rotate around the lifting plate, scraping away accumulated ash from the flue's inner wall, thus automatically cleaning the flue's inner wall. Activating an electric push rod drives an adjusting side plate, adjusting the distance between the cleaning scraper and the lifting plate, making the cleaning scraper suitable for flues of different inner diameters.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] like Figure 1-2 As shown, this utility model embodiment provides an energy-saving and environmentally friendly waste heat boiler flue cleaning device, including a cleaning component 2, which is installed on a hollow mounting cover plate 1;

[0047] The cleaning component 2 includes a first motor 201, a lead screw 207, a lifting plate 210, and mounting side plates 204. The first motor 201 is installed at the middle of the upper surface of the hollow mounting cover plate 1. The lower end of the output shaft of the first motor 201 passes through the hollow mounting cover plate 1. The lead screw 207 is arranged vertically, and its upper end is fixedly connected to the lower end of the output shaft of the first motor 201. The lifting plate 210 is threaded onto the lead screw 207. An annular mounting plate 211 is fitted onto the lifting plate 210. There are four mounting side plates 204, which are arranged in a ring array on the outer end face of the annular mounting plate 211. A cleaning scraper 206 is installed at the other end of the mounting side plate 204. The component also includes mounting holes. There are multiple mounting holes arranged in a ring on the hollow mounting cover plate 1. A limit plate is installed at the lower end of the lead screw 207. By setting the limit plate, the lifting plate 210 can be prevented from falling too far and separating from the lead screw 207.

[0048] Before starting the cleaning operation of the waste heat boiler flue, the installation cover plate can be placed on the flue opening to seal it. It is fixed through the installation hole. The structure below the installation cover plate extends into the inner cavity of the flue. During cleaning, the first motor 201 is started. The first motor 201 drives the lead screw 207 to rotate. The rotating lead screw 207 can automatically adjust the height of the lifting plate 210, thereby adjusting the height of the cleaning scraper 206 so that the cleaning scraper 206 can clean the inner wall of the flue at various heights.

[0049] In this embodiment, the cleaning component 2 also includes a second motor 202, a drive gear 203, and an annular driven gear ring. The second motor 202 is fixedly installed on the upper end of the lifting plate 210 by a mounting bracket. The drive gear 203 is fixedly fitted on the lower end of the output shaft of the second motor 202. The annular driven gear ring is fixedly installed on the inner wall of the annular mounting plate 211. The drive gear 203 meshes with the annular driven gear. The annular mounting plate 211 is rotatably fitted on the lifting plate 210 by bearings.

[0050] By starting the second motor 202, the second motor 202 drives the drive gear 203 to rotate. The rotating drive gear 203 can drive the annular mounting plate 211 to rotate through the annular driven gear, so that the cleaning scraper 206 can rotate around the lifting plate 210, so that the cleaning scraper 206 can scrape off the ash on the inner wall of the flue, thereby realizing automatic cleaning of the inner wall of the flue.

[0051] The cleaning component 2 also includes vertical guide rods 208. There are four vertical guide rods 208, which are fixed in a circular array to the lower end of the hollow mounting cover plate 1. The vertical guide rods 208 are arranged in the vertical direction, and the lower end of the vertical guide rods 208 passes through the lifting plate 210.

[0052] By setting a vertical guide rod 208, the lifting plate 210 can be prevented from rotating axially during vertical adjustment, thereby affecting the stability of the adjustment.

[0053] The lower end of the mounting side panel 204 is open;

[0054] like Figure 3-4 As shown, the cleaning assembly 2 also includes electric push rods 213 and adjusting side plates 205. There are four electric push rods 213, which are respectively installed at the lower openings of the four mounting side plates 204. There are four adjusting side plates 205, which are respectively installed at the lower openings of the four mounting side plates 204. The output ends of the four electric push rods 213 are respectively fixedly connected to the four adjusting side plates 205. The other end of the adjusting side plate 205 slides through the end of the mounting side plate 204 away from the lifting plate 210. The cleaning scraper 206 is fixedly connected to the end of the adjusting side plate 205 away from the lifting plate 210.

[0055] By activating the electric push rod 213, the adjusting side plate 205 is driven, thereby adjusting the distance between the cleaning scraper 206 and the lifting plate 210, so that the cleaning scraper 206 can be used for flues with different inner diameters.

[0056] The cleaning component 2 also includes a protective shell, which is fitted onto the first motor 201. The protective shell can protect the exposed first motor 201.

[0057] The cleaning component 2 also includes an air intake hose 212, the lower end of which is fixedly connected to the upper end of the lifting plate 210, and the upper end of which passes through the upper end of the hollow mounting cover plate 1.

[0058] The cleaning component 2 also includes jet heads 209, and multiple jet heads 209 are provided. The multiple jet heads 209 are fixedly connected to the side of the lifting plate 210 in a ring array.

[0059] An external air compressor can be connected to the upper end of the air intake hose 212, so that high-pressure air enters the lifting plate 210 through the air intake hose 212 and is finally ejected through the jet nozzle 209. The ejected high-pressure air can thoroughly purge the inside of the flue.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
