Description

Technical Field:

[0001] The utility model belongs to the field of boiler maintenance, and particularly relates to a boiler scale 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 carriers with a certain amount of heat energy. The original meaning of "pot" refers to a water container heated on fire, and "furnace" refers to a place for burning fuel. A boiler includes two major parts: a pot and a furnace. The hot water or steam generated in the boiler can directly provide the heat energy required 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. A boiler that generates steam is called a steam boiler, often simply referred to as a boiler, and is mostly used in thermal power stations, ships, locomotives and industrial and mining enterprises.

[0003] Existing boilers generally have a flat cylindrical structure. A tube bank is arranged in the inner cavity of the boiler, and water for heating is injected into the tubes. During the use of the boiler, the water added is generally tap water with high hardness. As a result, after long-term use of the boiler, a large amount of scale will adhere to the inner wall of the boiler tubes, affecting the heating effect of the boiler, and the energy consumption required by the boiler increases significantly. Content of the Utility Model:

[0004] The purpose of the utility model is to provide a boiler scale cleaning device, which overcomes the above-mentioned deficiencies of the prior art and effectively solves the existing problems of cleaning the scale on the inner wall of the boiler tubes.

[0005] The content of the utility model: A boiler scale cleaning device includes an insertion tube. At one end of the insertion tube, a scraping ring is coaxially sleeved. A plurality of support columns are evenly installed radially inward on the inner wall of the scraping ring. The outer ends of the support columns are fixedly connected to the outer wall of the insertion tube. The scraping ring is used to scrape the scale adhering to the inner wall of the boiler tubes.

[0006] Further, a chamfer is provided on the inner wall of the scraping end of the scraping ring.

[0007] Further, the outer circumferential surface of the scraping ring is in sliding fit with the inner circumferential surface of the boiler tube.

[0008] Further, a plurality of spray heads are evenly installed radially outward on the circumferential surface of one end of the insertion tube, and a water supply pipe is connected to the other end of the insertion tube.

[0009] Further, the spray heads are arranged on both sides of the scraping ring.

[0010] Further, one end of the insertion tube is tapered.

[0011] Further, a support block is sleeved on the other end of the intubation tube, and a handle is installed at the bottom end of the support block.

[0012] The beneficial effects of the utility model: By inserting the intubation tube into the boiler tube bank, the scale removal ring can quickly remove the scale adhering to the inner wall of the boiler tube bank, thereby ensuring the normal heating effect of the boiler and reducing the energy consumption required by the boiler. Brief description of the drawings:

[0013] Figure 1 is the usage state diagram of the utility model;

[0014] Figure 2 is the front view of the utility model;

[0015] Figure 3 is Figure 2 the cross-sectional view of part A-A in

[0016] In the figure: 1 intubation tube, 2 scale removal ring, 3 support column, 4 boiler tube bank, 5 nozzle, 6 water supply pipe, 7 support block, 8 handle. Specific implementation manner:

[0017] In order to have a clearer understanding of the technical features, purpose and effects of the utility model, the specific implementation manner of the utility model is now described with reference to the accompanying drawings:

[0018] As Figures 1 to 3 shown, a boiler scale cleaning device includes an intubation tube 1, a scale removal ring 2 is coaxially sleeved on one end of the intubation tube 1, a plurality of support columns 3 are uniformly installed radially inwards on the inner wall of the scale removal ring 2, the outer ends of the support columns 3 are fixedly connected with the outer wall of the intubation tube 1, the scale removal ring 2 is used for removing the scale adhering to the inner wall of the boiler tube bank 4, a chamfer is opened on the inner wall of the shoveling end of the scale removal ring 2, and the outer circumferential surface of the scale removal ring 2 is slidably attached to the inner circumferential surface of the boiler tube bank 4.

[0019] Specifically, by inserting the intubation tube 1 into the boiler tube bank 4, the scale removal ring 2 can quickly remove the scale adhering to the inner wall of the boiler tube bank 4.

[0020] During the actual use process, the sealing covers at both ends of the boiler are opened, and the intubation tube 1 is aligned with a single boiler tube bank 4 and inserted. When the intubation tube 1 continues to extend, the scale removal ring 2 quickly shovels off the scale adhering to the inner wall of the boiler tube bank 4; a chamfer is opened on the inner wall of the shoveling end of the scale removal ring 2, so that the scale removal ring 2 forms a structure similar to a ring knife, which further facilitates the scale removal ring 2 to quickly shovel off the scale; by repeating the above steps, the scale of multiple arranged boiler tube banks 4 can be effectively removed.

[0021] As Figures 1 to 3As shown in the figure, a device for cleaning boiler scale is provided. A number of spray nozzles 5 are evenly installed radially outward on the circumferential surface at one end of the insertion tube 1. A water supply pipe 6 is connected to the other end of the insertion tube 1. The spray nozzles 5 are arranged on both sides of the scraping ring 2. One end of the insertion tube 1 is in a sharp conical shape. A support block 7 is sleeved on the other end of the insertion tube 1. A handle 8 is installed at the bottom end of the support block 7.

[0022] Specifically, the water sprayed by a number of spray nozzles 5 can pre-soak and clean the inner wall of the boiler tube 4 after scraping.

[0023] During actual use, the water supply pipe 6 conveys the external high-pressure water source into the inner cavity of the insertion tube 1. The water sprayed by a number of spray nozzles 5 located at the front end of the scraping ring 2 can pre-soak the inner wall of the boiler tube 4, making the hard scale soften, which is convenient for the subsequent scraping ring 2 to quickly scrape it off. When the scraping ring 2 removes the scale, the water sprayed by a number of spray nozzles 5 located at the rear end of the scraping ring 2 can perform secondary flushing on the inner wall of the boiler tube 4 to make it cleaner. The scraped scale and the cleaning water are discharged through the opening at one end of the tube. If the inner cavity of the boiler tube 4 is severely blocked, the sharp conical shape at one end of the insertion tube 1 can quickly pierce it open. For ease of use, on-site operators can hold the handle 8 and quickly insert the insertion tube 1 into the boiler tube 4.

[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
