Description

Technical Field

[0001] This utility model relates to the technical field of centralized heating equipment, specifically to a dust filtration device for centralized heating equipment. Background Technology

[0002] In addition to releasing a large amount of heat, the combustion of fuel in heating equipment also produces a large amount of flue gas. Flue gas is a mixture of gaseous and solid substances. The gaseous substances mainly include carbon dioxide, sulfur dioxide, carbon monoxide, hydrocarbons, carbon oxides, nitrogen, and oxygen. The solid substances are soot. Due to the presence of soot, boiler exhaust is gray or even black, which can clog the boiler and cause environmental pollution.

[0003] The existing filter screen or filter plate is installed close to the inside of the filter tube, which makes it inconvenient for staff to remove the filter screen or filter plate, increases the removal time, and makes it difficult to quickly replace or clean the filter screen of the device.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] like Figure 1 A dust filtration device for centralized heating equipment is shown, comprising a base 1, on which a filter cylinder 2 is disposed. The filter cylinder 2 is composed of a first cylinder 3 and a second cylinder 4 connected together. The joint between the first cylinder 3 and the second cylinder 4 has an opening and is connected. The first cylinder 3 is fixed to the base 1, and the second cylinder 4 is slidably connected to the base 1. An annular groove 31 is provided on the inner wall of the opening of the first cylinder 3, and a filter plate 32 is embedded in the groove 31. An annular flange 41 is provided on the outer wall of the opening of the second cylinder 4, and the flange 41 is inserted into the groove 31. A sliding groove 5 is provided on the base 1, and a sliding seat 51 is provided in the sliding groove 5. The second cylinder 4 is fixed on the sliding seat 51, and the sliding seat 51 is slidably connected to the sliding groove 5 by a cylinder 52.

[0017] In a preferred embodiment, an air inlet 33 is provided on the first cylinder 3, and an air outlet 42 is provided on the second cylinder 4. Valves are provided on both the air inlet 33 and the air outlet 42.

[0018] In a preferred embodiment, a sealing ring 43 is provided on the outer wall of the flange 41, and the flange 41 is tightly fitted with the groove 31.

[0019] The present invention discloses a dust filtration device for centralized heating equipment, which designs the filter cylinder as a double-cylinder butt joint structure to facilitate quick disassembly and replacement of the filter plate.

[0020] Specifically, after the smoke and dust are introduced into the filter cylinder 2 through the air inlet 33, the impurities in the smoke and dust are filtered and separated by the filter screen on the filter plate 32 along the path from the first cylinder 3 to the second cylinder 4, and the filtered smoke and dust are safely discharged through the air outlet 42.

[0021] When the filter plate 32 needs to be disassembled and replaced, the cylinder 52 drives the slide block 51 to slide, which in turn moves the second cylinder 4, causing it to separate from the opening of the first cylinder 3. This allows the filter plate 32 in the groove 31 to be easily removed, cleaned, and replaced. Then, by controlling the reset of the second cylinder 4, it is connected to the first cylinder through a docking, with its flange 41 inserted into the corresponding groove 31, and tightly sealed by the sealing ring 43.

[0022] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
