Description

Technical Field

[0001] The present invention relates to the technical field related to coal conveying flushing, and particularly relates to a coal conveying flushing device for a power plant. Background Art

[0002] In a thermal power plant, coal is used as fuel to produce electric energy. The coal material is conveyed to the power plant through a conveyor. During the conveying process, it is necessary to flush the conveyor to prevent the accumulation of coal slag and affect the subsequent normal conveying.

[0003] Currently, the coal conveying flushing devices on the market generally connect a water pipe through a water pump and set spray nozzles on the water pipe. By supplying water through the water pump and spraying water with the spray nozzles, the belt on the conveyor is directly flushed. Although it can achieve the flushing effect, its function is relatively single and the cleaning is not thorough.

[0004] In the related art, the depth cleaning of the coal conveying return belt is realized by flushing with a flushing nozzle and further scrubbing with a scraping strip. The sewage during the cleaning process is collected through a water collecting tank, which can reduce the dust and environmental pollution in the coal conveying area. Although it can make the cleaning more thorough, in actual use, its function is relatively single, and the residual coal slag is mixed with the cleaned sewage, resulting in easy blockage of the sewage collection container, affecting subsequent use and bringing inconvenience to the flushing work and being inconvenient for the staff to use.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0059] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0060] In view of the current prior art, the flushing device generally connects a water pipe through a water pump, and a spray head is arranged on the water pipe. By supplying water through the water pump and spraying water with the spray head, the belt on the conveyor belt is directly flushed. Although it can achieve the flushing effect, its function is relatively single and the cleaning is not thorough.

[0061] In the related art, the deep cleaning of the coal conveying return belt is realized by flushing with a flushing spray head and further scrubbing with a scraping strip. The sewage in the cleaning process is collected through a water collecting tank, which can reduce the dust and environmental pollution in the coal conveying area. Although it can make the cleaning more thorough, in actual use, its function is relatively single, and the residual coal cinder is mixed with the cleaned sewage, resulting in easy blockage of the sewage collection container, affecting subsequent use and bringing inconvenience to the flushing work and being inconvenient for the staff to use.

[0062] As Figures 1-5 shown, an embodiment of the present invention provides a coal conveying flushing device for a power plant, including: a belt conveyor 10, with a housing 11 fixedly connected to its bottom; a flushing pipe 12 arranged on the housing 11, the other end of the flushing pipe 12 is connected to a water tank through a water pump for flushing the belt conveyor 10; a box body 20 fixedly connected to the belt conveyor 10; a baffle 21 fixedly connected to the top of the box body 20, and the baffle 21 is fixedly connected to the flushing pipe 12; a rod body one 22 rotatably connected inside the flushing pipe 12; a brush 23 fixedly connected to the outside of the rod body one 22; a driving mechanism 24 arranged on the flushing pipe 12 for driving the two rod bodies one 22 to rotate; a drain pipe 25 arranged on the box body 20; a filter housing 30 slidably connected to the box body 20; filter holes 31 opened on the filter housing 30; a fixed seat 40 fixedly connected to the side of the box body 20; a plate body one 41 slidably connected inside the fixed seat 40; a plate body two 42 fixedly connected to one end of the rod body one 22, the plate body two 42 is connected to the plate body one 41 through a connecting rod 43, and the connecting rod 43 is rotatably connected to the plate body two 42 and the plate body one 41; a slider 44 fixedly connected to the plate body one 41; a plate body three 45 arranged on the side of the slider 44.

[0063] After the belt conveyor 10 is installed at the designated position, the flushing pipe 12 is connected to the water pump and the water tank in sequence, and the coal to be transported is placed on the belt conveyor 10, and then the driving motor on the belt conveyor 10 is turned on to transport the coal through the belt. While transporting, the water pump is turned on to allow the water pump to transport the flushing water in the water tank to the flushing pipe 12, and spray the flushing water on the belt of the belt conveyor 10 through the nozzle on the flushing pipe 12 to flush the belt (wherein the belt conveyor 10 and the water pump are both prior art, so they will not be described in detail). While flushing, the driving mechanism 24 is turned on to drive the two rod bodies 22 to rotate and drive the two sets of brushes 23 to rotate, so as to flush the belt while flushing the belt, thereby improving the cleaning effect, and the flushed magazines and flushing water flow into the box body 20 along the inclined direction of the shell 11;

[0064] The solid-liquid mixed flushing water is filtered by the filter shell 30 in the box body 20. After the water passes through the filter hole 31, it falls into the box body 20. The coal slag remains in the box body 20. The waste water can be discharged through the drain pipe 25 by opening the valve on the drain pipe 25, or the filter shell 30 can be pulled to slide out of the box body 20, so that the filtered coal slag can be cleaned up conveniently.

[0065] When the driving mechanism 24 is opened, the plate body 2 42 is driven, and then the plate body 1 41 is pulled by the connecting rod 43 to slide reciprocatingly up and down in the fixed seat 40. While sliding, the slider 44 and the plate body 3 45 are driven to slide reciprocatingly up and down. When the plate body 3 45 slides upward, the filter shell 30 is pushed to slide upward. Then, when the plate body 3 45 slides downward, the filter shell 30 slides downward until it is reset due to its own gravity and the downward impact force of the wastewater, forming an up and down reciprocating vibration screening effect, reducing the possibility of coal slag blocking the filter hole 31, thereby facilitating the wastewater to pass through the filter hole 31.

[0066] Optionally, the driving mechanism 24 is composed of a motor, a sprocket and a chain. The motor is fixedly connected to the flushing pipe 12, and the output end is fixedly connected to one end of the rod body 22. The sprocket is fixedly connected to the same-direction ends of the two rod bodies 22 and is connected through the chain transmission.

[0067] By turning on the motor, the output end of the motor drives one rod body 22 to rotate, and at the same time, the other rod body 22 is driven to rotate through the transmission connection of the chain and the sprocket.

[0068] Optionally, a groove 451 is provided on the plate body 45, and the filter shell 30 is embedded in the groove 451. The groove 451 limits the filter shell 30 to prevent the filter shell 30 from sliding out of the box body 20 during normal use.

[0069] Optionally, the third plate body 45 is slidably connected to the slider 44, and a set screw one 50 is threadedly connected to the slider 44, and one end of the set screw one 50 is inserted into the third plate body 45.

[0070] When disassembling the filter housing 30, rotate the set screw one 50. After canceling the limit on the third plate body 45, push the third plate body 45 so that it passes through the slider 44 and does not contact the filter housing 30, thereby facilitating the sliding of the filter housing 30 out of the box body 20.

[0071] Optionally, a stop block 46 is fixedly connected to the bottom of the third plate body 45. When the third plate body 45 slides in the slider 44, the stop block 46 plays a limiting role in preventing the third plate body 45 from detaching from the slider 44.

[0072] Optionally, the second rod body 60 is rotatably connected inside the flushing pipe 12; the blocking rod 61 is fixedly connected to the outside of the second rod body 60; the first gear 62 is fixedly connected to one end of the first rod body 22; the second gear 63 is fixedly connected to one end of the second rod body 60; the third gear 64 is arranged at one end of the second rod body 60, and the first gear 62, the second gear 63 and the third gear 64 are meshed in sequence.

[0073] When the first rod body 22 drives the brush 23 to clean the belt conveyor 10, the first rod body 22 drives the first gear 62 to rotate. Subsequently, through the transmission of the first gear 62, the second gear 63 and the third gear 64, the second rod body 60 drives the blocking rod 61 to rotate, so as to realize that the brush 23 rotates following the first rod body 22. When cleaning the belt conveyor 10, the blocking rod 61 plays a cleaning role on the brush 23.

[0074] Optionally, the third rod body 70 is slidably connected inside the first rod body 22, and the third gear 64 is fixedly connected to one end of the third rod body 70; the set screw two 71 is rotatably connected to the third gear 64, and the set screw two 71 is threadedly connected to the housing 11.

[0075] When the blocking rod 61 is not needed, before starting the equipment, push the third gear 64 so that it disengages from the second gear 63. After the set screw two 71 contacts the housing 11, rotate the set screw two 71. After the set screw two 71 is threadedly connected to the housing 11, limit the position of the third gear 64. Subsequently, when the driving mechanism 24 is started, the third gear 64 and the second rod body 60 do not rotate, so that the blocking rod 61 does not work. On the contrary, the first rod body 22 and the second rod body 60 rotate simultaneously.

[0076] Optionally, the cross section of the third rod body 70 is rectangular, which facilitates the third gear 64 to drive the second rod body 60 to rotate through the third rod body 70 when the second gear 63 is meshed with the third gear 64.

[0077] Optionally, a set screw three 72 is threadedly connected to the rod body one 22. After the gear three 64 meshes with the gear two 63, the set screw three 72 is rotated to fix the position of the rod body three 70, so that the meshing of the gear three 64 and the gear two 63 is more firm and the stability is improved.

[0078] Optionally, a plurality of filter housings 30 are provided. The plurality of filter housings 30 can be used simultaneously or individually, improving the practicability.

[0079] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
