Description

Technical Field

[0001] The utility model relates to the technical field of dust cleaning devices, in particular to a dust cleaning device for a kiln tail boiler with energy saving and noise reduction. Background Technique

[0002] The dust cleaning device for a kiln tail boiler is a device used to clean the accumulated ash at the tail of an industrial kiln. During the operation of the industrial kiln, dust and other solid particles in the flue gas will deposit on the inner wall of the boiler. Over time, a thick layer of accumulated ash will form, which will affect the heat transfer efficiency of the boiler, increase energy consumption, and may even cause blockage of the boiler.

[0003] Some existing dust cleaning devices spray the dust on the inner wall through high-pressure nozzles to make the dust fall off. However, the cleaned water is not treated by personnel to enable secondary recycling, which leads to a large waste of water resources and unreasonable utilization of water resources. Moreover, when cleaning the ash through high-pressure nozzles, noise will be generated when the water flow passes through the nozzles at a high pressure, which will affect the normal work of operators. Content of the Utility Model

One side of the first slider is fixedly connected with a filter screen. The filter screen is slidably connected inside the collection box through the first sliders on both sides. The middle of the front end of the filter screen is fixedly connected with an operation handle.

[0007] Through the above technical solution, the dust on the inner wall of the boiler body is cleaned by a high-pressure nozzle group. After the dust is mixed with water, by opening the valve at the bottom of the boiler body, it enters the filter screen at the bottom. The filter screen can separate the dust, leaving the dust on the surface of the filter screen. The water flow is purified through the filter screen and flows to the collection box at the bottom for unified collection, which is convenient for personnel to carry out secondary recycling later. And personnel can disassemble the filter screen through the operating handle to handle the dust attached to the surface, avoiding the long-term accumulation of dust and affecting the subsequent filtering effect. The rubber material used for the sound insulation layer can reduce the noise generated by the high-pressure nozzle group during operation, providing a good working environment for personnel.

[0008] As a further improvement of the above solution, a movable cover is provided on the upper surface of the boiler body, and a sound insulation layer is provided in the middle of the lower surface of the movable cover. The material of the sound insulation layer is rubber.

[0009] Through the above technical solution, the rubber material used for the sound insulation layer can reduce the noise generated by the high-pressure nozzle group during operation, providing a good working environment for personnel.

[0010] As a further improvement of the above solution, a handle is fixedly connected to the surface of the movable cover, and the number of handles is two, which are respectively fixedly connected to both sides of the upper surface of the movable cover.

[0014] As a further improvement of the above solution, a water pump is fixedly installed on one side of the inner bottom wall of the water collection tank through bolts.

[0015] Through the above technical solution, after the water pump is started, the water inside the water collection tank is pressurized and conveyed to the spray pipe through the output end, and then sprayed out through the high-pressure nozzle group to clean the dust on the inner wall of the boiler body.

[0016] As a further improvement of the above solution, the output end of the water pump is fixedly connected to a spray pipe, and the spray pipe is arranged inside the boiler body.

[0017] Through the above technical solution, after the water pump is started, the water inside the water collecting tank is pressurized and conveyed to the spray pipe through the output end, and the spray pipe then conveys the water flow to the high-pressure nozzle group on the outer surface.
