Description

Technical Field

[0001] This utility model relates to the field of flue cleaning technology, and in particular to a water seal cleaning device for flues. Background Technology

[0002] Waste incineration is an effective means of reducing, harmlessly treating, and recycling waste, and is widely used in the treatment of urban solid waste. During the waste incineration process, the combustible components in the waste burn at high temperatures, producing high-temperature flue gas that is discharged through the flue.

[0003] However, the composition of waste is complex. In addition to combustibles, it also contains a large amount of inorganic matter, metals, and non-combustible residues. These substances undergo a series of complex physical and chemical changes during incineration. Some substances will enter the flue with the flue gas. If the dust in the flue is not cleaned, the straight flue is prone to blockage, leading to shutdown.

[0004] Based on this, in order to realize online cleaning of flue gas during flue exhaust, we propose a water seal cleaning device for flues. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies, such as the easy blockage of straight flues leading to boiler shutdowns, and to propose a water-sealed ash removal device for flues.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a water seal cleaning device for flues, including:

[0008] The ash discharge pipe of the flue extends into the water tank below the flue via a sliding mechanism.

[0009] The water tank includes four peripheral surfaces and a dust accumulation bottom surface and a sealing bottom surface connected between the bottoms of the four peripheral surfaces. The sealing bottom surface is located above the dust accumulation bottom surface and is used to be close to the bottom of the ash discharge pipe after the water tank is moved. A transition surface is also formed between the dust accumulation bottom surface and the sealing bottom surface.

[0010] Furthermore, the sliding mechanism includes two guide rails fixed on the platform, and mounting seats are fixedly installed on both sides of the water tank. The bottom of the mounting seat is rotatably connected to a track wheel via a wheel frame, and the track wheel slides in contact with the guide rails.

[0011] Furthermore, both ends of the track wheel are fixed with axles that pass through the wheel frame, and a gear is fixedly installed on the outer side of one of the axles;

[0012] A limit rod is movably inserted into the end face of the mounting base via a spring, and the bottom end of the limit rod is engaged with the gear.

[0013] Furthermore, two hanging lugs are formed at both ends of the water tank, and positioning pins for sliding limit of the water tank are fixed at both ends of the guide rail.

[0014] Furthermore, a cover plate is fixedly connected to the upper end of the platform via a bracket, and the cover plate covers the water level corresponding to the sealed bottom surface.

[0015] Furthermore, a side baffle is fixedly installed on the side of the ash discharge pipe, and the bottom of the side baffle is close to the sealing bottom surface.

[0016] The present invention proposes a water-sealed ash removal device for flues, which has the following advantages: The ash removal device uses a water tank to water-seal the bottom of the ash discharge pipe. Ash in the flue falls into the water tank for collection. After collection, the position of the water tank can be changed to move it to one side for ash removal.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3As an embodiment of this utility model, a water seal cleaning device for a flue is disclosed. Specifically, the device includes a water tank 3 that slides below the flue 2 via a sliding mechanism 1. The ash discharge pipe 21 of the flue 2 extends into the liquid level of the water tank 3. In other words, in this embodiment, the water tank 3 is filled with water, and the tail end of the ash discharge pipe 21 is sealed with water to prevent air leakage in the flue 2.

[0023] The water tank 3 includes four peripheral surfaces 31 and a dust accumulation bottom surface 32 and a sealing bottom surface 33 connected between the bottoms of the four peripheral surfaces 31. The sealing bottom surface 33 is located above the dust accumulation bottom surface 32 and is used to move closer to the bottom of the ash discharge pipe 21 after the water tank 3 is moved. A transition surface 34 is also formed between the dust accumulation bottom surface 32 and the sealing bottom surface 33.

[0024] In some embodiments, the sliding mechanism 1 of this utility model includes two guide rails 11 fixed on the platform 4. The two guide rails 11 are horizontally arranged. Specifically, the guide rails 11 are configured as tracks. Mounting seats 12 are fixedly installed on both sides of the water tank 3. The bottom of the mounting seat 12 is rotatably connected to the track wheel 14 through the wheel frame 13. The track wheel 14 slides against the guide rail 11. That is, in this embodiment, the track wheel 14 and the guide rail 11 slide together to achieve convenient movement control of the water tank 3. When cleaning the ash, the water tank 3 can be pulled to the right to expose the water level corresponding to the bottom surface 32 of the accumulated ash. The accumulated ash inside the water tank can be manually removed. For safety during the ash removal process, after pulling to this position, the sealed bottom surface 33 position is moved to below the ash discharge pipe 21. There is still a water seal here to ensure that the flue does not leak air.

[0025] Based on the above embodiments, in order to lock the position of the water tank 3, both ends of the track wheel 14 in this embodiment are fixed with axle rods 15 that pass through the wheel frame 13, and a gear 16 is fixedly installed on the outside of one of the axle rods 15.

[0026] A limiting rod 18 is movably inserted into the end face of the mounting base 12 via a spring 17, and the bottom end of the limiting rod 18 is engaged with the gear 16.

[0027] In other words, in this embodiment, when the bottom surface 32 of the water tank 3 and the sealing bottom surface 33 are located below the ash discharge pipe 21 for cleaning or removing ash, the bottom end of the limiting rod 18 can be engaged with the outside of the gear 16 to lock the rotation of the track wheel 14. At this time, the track wheel 14 cannot rotate on the guide rail 11, thus maintaining the positional stability of the entire water tank 3. Of course, when it is necessary to move the water tank 3, the limiting rod 18 can be pulled upward to disengage it from the gear 16. At this time, the gear 16 is in a state of free rotation, thus realizing the positional control of the water tank 3.

[0028] Furthermore, in this embodiment, two hanging ears 35 are formed at both ends of the water tank 3. The hanging ears 35 can be used to connect structural components such as traction ropes to achieve convenient traction control of the water tank 3. The two ends of the guide rail 11 are fixed with positioning pins 19 for limiting the sliding of the water tank 3. The positioning pins 19 are used to stop the sliding of the track wheel 14 to prevent the water tank 3 from slipping off the guide rail 11.

[0029] In this preferred embodiment, the positioning pin 19 can be connected to the top of the guide rail 11 by means of a threaded connection. The purpose of adopting this detachable structure design is to realize convenient installation of the water tank 3 and convenient disassembly and maintenance thereafter.

[0030] Furthermore, in this embodiment, a cover plate 6 is fixedly connected to the upper end of the platform 4 by a bracket 5, and the cover plate 6 covers the water level corresponding to the sealing bottom surface 33.

[0031] In addition, a side baffle 7 is fixedly installed on the side of the ash discharge pipe 21, and the bottom of the side baffle 7 is close to the sealing bottom surface 33.

[0032] In actual operation, when the flue gas flows inside the flue 2, the internal diameter of the ash discharge pipe 21 increases, thus reducing the flue gas velocity. Dust in the flue gas settles at this point and falls into the water tank 3. Because the water tank 3 and the flue 2 have a certain water level, the flue's sealing is ensured.

[0033] When the ash in the water tank 3 accumulates to a certain extent, the water tank 3 is supported on the guide rail 11 by the track wheel 14. The water tank 3 is pulled outward by the traction member connected to the hanging ear 35. When it stops at the right positioning pin 19, the ash inside the water tank 3 can be manually removed. For safety during the ash removal process, after being pulled to this position, the sealing bottom surface 33 is moved to the bottom of the flue 2. There is still a water seal here to ensure that the flue 2 does not leak air. In this preferred embodiment, the distance between the sealing bottom surface 33 and the bottom of the ash discharge pipe 21 is 2-3mm. The water tank 3 is provided with a cover plate 6 to prevent positive pressure water splashing. The cover plate 6 is supported by the bracket 5. A side baffle 7 is also provided on the ash removal side. This avoids the situation where positive pressure water in the flue 2 causes a large area of ​​water splashing and injury.

[0034] In summary, the ash removal device of this utility model uses a water tank 3 to water seal the bottom of the ash discharge pipe 21. The soot in the flue 2 falls into the water tank 3 for collection. After collection, the position of the water tank 3 can be changed to move it to one side for ash removal. During the ash removal process, the bottom of the ash discharge pipe 21 is water sealed again by the sealing bottom surface 33 to ensure the safety of the operation during the ash removal process. The overall structure design is simple and effectively improves the convenience of ash removal operation of the flue 2.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
