Description

Technical Field

[0001] The present invention relates to the field of boiler maintenance equipment, and more specifically, to a boiler furnace ash cleaning device. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy in fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. A boiler mainly consists of two parts: a boiler shell and a furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's livelihood, or can be converted into mechanical energy through a steam power device, or further converted into electrical energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and has a small amount of application in industrial production.

[0003] The boiler furnace is a place for heat exchange. Water-cooled walls are arranged inside the furnace. When the fuel burns inside the furnace, the water-cooled walls are heated, and the water in the water-cooled walls absorbs heat energy to achieve heat exchange. The water-cooled walls are pipes distributed in a circle. For example, a boiler water-cooled wall and a boiler with the patent number CN214370352U, its water-cooled wall is a common type of boiler water-cooled wall. Ash will inevitably be generated during fuel combustion, and some ash will adhere to the water-cooled walls. When the dust adheres thickly, it greatly affects the heat exchange efficiency. Therefore, it is necessary to regularly maintain the water-cooled walls inside the furnace.

[0004] At present, the method for cleaning the water-cooled walls is that workers enter the furnace through the boiler manhole and use a broom and a high-pressure water gun to flush and clean the water-cooled walls. This cleaning method can only clean one side of the water-cooled wall pipes and it is very difficult to clean the other side of the water-cooled wall pipes, so the cleaning is not comprehensive enough; before cleaning, it is necessary to first use a broom to scrape and clean the dust on the pipe surface. When scraping, a large amount of dust will be generated, which affects the vision of the cleaning workers and cannot scrape and rinse at the same time. Summary of the Invention

A limit roller 113 is installed inside the roller support seat 112. A rotating shaft passes through between the limit roller 113 and the roller support seat 112, and the limit roller 113 and the roller support seat 112 are movably connected through the rotating shaft. With this setting, when cleaning the water-cooled wall pipe, the limit roller 113 directly contacts the water-cooled wall pipe. When moving, the limit roller 113 rotates, and the rolling friction with the water-cooled wall pipe is more labor-saving.

[0029] Refer to Figures 1-4, the top end of the support rod 102 passes through the center of the support plate 101, and the support rod 102 and the support plate 101 are fixed by welding. A handle 121 is welded to one side of the bottom end of the support rod 102. Such a setting facilitates holding the handle 121 at the bottom end of the support rod 102 by hand and pushing the whole forward to clean the water-cooled wall pipe.

[0030] Refer to Figure 2 , the flushing pipe 103 movably passes through the center of the support rod 102, and a water supply joint 132 is provided at the bottom end of the flushing pipe 103. An anti-slip rubber sleeve 131 is nested on the outer side of the bottom end of the flushing pipe 103. Such a setting enables the extension length of the flushing pipe 103 to be adjusted and also facilitates holding the anti-slip rubber sleeve 131 by hand to control the flushing pipe 103.

[0031] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 , the pipe back side brush 104 is nested and installed at the top end of the flushing pipe 103, and a big head screw 141 is embedded on one side of the pipe back side brush 104. The pipe back side brush 104 and the flushing pipe 103 are fixed by extrusion and limitation with the big head screw 141. The big head screw 141 and the pipe back side brush 104 are connected by screw thread. Such a setting facilitates the installation and disassembly and replacement of the pipe back side brush 104.

[0032] Refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the water outlet socket 105 is inserted and installed at the top end of the flushing pipe 103, and the water outlet socket 105 and the flushing pipe 103 are connected by screw thread. Such a setting facilitates the installation and disassembly and replacement of the water pipe socket 105.

[0033] Refer to Figure 5 , wing-shaped water outlet pipes 151 are symmetrically arranged on the left and right sides of the water outlet socket 105, and water outlet holes 152 are evenly formed on one side of the wing-shaped water outlet pipes 151. Such a setting facilitates water outlet.

[0034] Refer to Figure 1 , Figure 2 and Figure 7 , the pipe front side brush 106 is inserted and installed inside the front brush seat 111. Such a setting facilitates the installation and disassembly and replacement of the pipe front side brush 106.

[0035] For more convenient use, a valve is provided at the bottom end of the flushing pipe 103 to facilitate controlling the water flow.

[0036] When cleaning the water-cooled wall pipes inside the boiler furnace: First, insert the water supply pipe outside the water supply pipe joint 132. Then, open the manhole door of the boiler. Next, the cleaning personnel enter the boiler interior through the manhole, and pass the whole of the present invention to the hands of the cleaning personnel through the manhole. The cleaning personnel hold the handle 121 with one hand and the anti-slip rubber sleeve 131 with the other hand, and rotate the anti-slip rubber sleeve 131 so that the flushing pipe 103 rotates accordingly until the wing-shaped water outlet pipe 151 is parallel to the water-cooled wall pipe. Then, insert the wing-shaped water outlet pipe 151 through the gap of the water-cooled wall pipe. Then, rotate the flushing pipe 103 so that the wing-shaped water outlet pipe 151 is perpendicular to the water-cooled wall pipe. As Figure 8 shown, at this time, the pipe back side brush 104 is on the back side of the water-cooled wall pipe, and the pipe front side brush 106 is on the front side of the water-cooled wall pipe. Then, lift the support plate 101 upward so that the pipe front side brush 106 and the limit roller 113 are close to the front side of the water-cooled wall pipe. Then, open the water supply pipe switch, and the water passes through the flushing pipe 103, the water outlet pipe socket 105 and the wing-shaped water outlet pipe 151, and finally flows out from the water outlet hole 152, spraying on the back side of the pipe and the pipe back side brush 104. At the same time, reciprocally push the support rod 102 so that the pipe front side brush 106 and the pipe back side brush 104 clean the surface of the pipe. When cleaning, the water outlet hole 152 sprays to prevent dust from flying.
