Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, specifically a scraper conveyor with self-cleaning function. Background Technology

[0002] A scraper conveyor is a conveying device that uses a scraper chain to transport bulk materials within a trough. It is widely used in industries such as mining, metallurgy, and chemicals. It can continuously transport materials and features high conveying capacity, wide applicability, and simple structure, playing a vital role in material transportation.

[0003] When a lot of material adheres to the scraper, it is difficult to completely remove this material, resulting in material residue accumulation, which affects the subsequent conveying efficiency. Moreover, the scraper is prone to being damp after cleaning, and there is a lack of special drying measures. Over time, this will cause the scraper to rust and be damaged, increasing maintenance costs. Therefore, there is a problem of not being able to clean the scraper conveyor.

[0004] Therefore, this utility model provides a scraper conveyor with self-cleaning function to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a scraper conveyor with a self-cleaning function, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scraper conveyor with self-cleaning function, comprising a scraper conveyor body, a cleaning mechanism fixedly connected to the upper surface of the scraper conveyor body, a drying mechanism fixedly connected to the inner wall of the cleaning mechanism, the cleaning mechanism comprising a fixed outer shell fixedly connected to the upper surface of the scraper conveyor body, a servo motor fixedly connected to the side surface of the fixed outer shell, a rotating shaft fixedly connected to the output shaft of the servo motor passing through the inner wall of the fixed outer shell, a cleaning brush fixedly connected to the outer surface of the rotating shaft, and multiple sets of fans embedded in the upper surface of the fixed outer shell; the drying mechanism comprising a water outlet pipe fixedly connected to the inner wall of the fixed outer shell, multiple sets of atomizing nozzles fixedly connected to the outer surface of the water outlet pipe, a fixed plate fixedly connected to the upper surface of the scraper conveyor body, a heating outer shell fixedly connected to the upper surface of the fixed plate, multiple sets of resistance heating rods fixedly connected to the inner wall of the heating outer shell, and a blower fixedly connected to the upper surface of the heating outer shell.

[0007] Furthermore, a sliding frame is slidably connected to the inner wall of the fixed housing, one end of the sliding frame passes through the outer surface of the fixed housing and is fixedly connected to a connecting plate, and a filter plate is fixedly connected to the inner wall of the sliding frame, the filter plate being disposed below the fan.

[0008] The above technical solution uses a sliding frame that is slidably connected to a fixed housing. The connecting plate facilitates the removal of the filter plate for cleaning or replacement. The filter plate prevents the cleaning brush from throwing materials toward the fan, thus protecting the fan.

[0009] Furthermore, the cleaning mechanism also includes a water tank fixedly connected to the outer surface of the scraper conveyor body, a water pump fixedly connected to the upper surface of the water tank, the water inlet of the water pump extending into the interior of the water tank, and an observation window fixedly connected to the outer surface of the water tank.

[0010] The above technical solution uses a water tank to store the water required for cleaning and provide a water source for the atomizing nozzles; a water pump pressurizes the water in the tank and delivers it to the outlet pipe to ensure the normal operation of the atomizing nozzles; and an observation window allows operators to monitor the water level in the tank at any time, add water in time, and avoid affecting the cleaning process due to water shortage.

[0011] Furthermore, the outlet of the water pump is fixedly connected to a fixed pipe via a pipeline. The outer surface of the fixed pipe is connected to one end of the outlet pipe. The outlet pipe is provided in three sets, which are respectively located on both sides of the rotating shaft. The atomizing nozzles on the outer surfaces of the two sets of outlet pipes are arranged opposite each other.

[0012] Using the above technical solution, a fixed pipe connects the water pump and the outlet pipe, distributing water evenly to each outlet pipe. The three sets of outlet pipes are respectively set on both sides of the rotating shaft, and the atomizing nozzles on both sides are set opposite each other, which can spray water on the scraper surface from different directions to ensure a comprehensive spraying range.

[0013] Furthermore, a heat-conducting mesh is fixedly connected to the inner wall of the heating shell, and the outer surface of the heat-conducting mesh is in contact with the outer surface of the resistance heating rod.

[0014] By adopting the above technical solution, the heat generated by the resistance heating rod can be evenly transferred through the heat-conducting mesh, making the air inside the heating shell more evenly heated, avoiding local overheating or underheating, improving the quality of hot air, and thus enhancing the drying effect.

[0015] Furthermore, an air distribution plate is fixedly connected to the outer surface of the fixed plate, the air distribution plate is located below the heating shell, and a control surface is fixedly connected to the outer surface of the scraper conveyor body.

[0016] By adopting the above technical solution, the hot air blown out by the heating shell can be evenly distributed through the air distribution plate, so that all parts of the scraper conveyor body are heated evenly, and the control panel makes it easy for operators to control the working status of the cleaning mechanism and the drying mechanism.

[0017] Beneficial effects

[0018] This invention provides a scraper conveyor with a self-cleaning function. Compared with the prior art, it has the following advantages:

[0019] 1. This scraper conveyor with self-cleaning function uses a servo motor to drive the cleaning brush to rotate, which can effectively clean and recycle small materials on the scraper. The PTFE filter plate can prevent materials from being thrown towards the fan, ensuring the normal operation of the fan. During comprehensive cleaning, the atomizing nozzle sprays water at multiple angles. With the help of a water pump and fixed pipeline, it is easy to thoroughly clean the scraper surface, reduce maintenance costs, and improve the material recovery rate and equipment durability.

[0020] 2. This scraper conveyor with self-cleaning function facilitates the drying of scrapers through a drying mechanism. The heat generated by the resistance heating rod inside the heating shell is evenly transferred through the heat conduction mesh. The blower blows hot air toward the air distribution plate, which evenly distributes the hot air on the scraper surface, accelerating the evaporation of moisture from the scraper and achieving rapid drying.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figures 1 to 4 This application provides a scraper conveyor with self-cleaning function, including a scraper conveyor body 1. A cleaning mechanism 2 is fixedly connected to the upper surface of the scraper conveyor body 1, and a drying mechanism 3 is fixedly connected to the inner wall of the cleaning mechanism 2. The cleaning mechanism 2 includes a fixed outer shell 208 fixedly connected to the upper surface of the scraper conveyor body 1. A servo motor 201 is fixedly connected to the side surface of the fixed outer shell 208. The output shaft of the servo motor 201 passes through the inner wall of the fixed outer shell 208 and is fixedly connected to a rotating shaft 211. A cleaning mechanism 3 is fixedly connected to the outer surface of the rotating shaft 211. The brush 207 and the upper surface of the fixed housing 208 are embedded with multiple sets of fans 202. The drying mechanism 3 includes a water outlet pipe 212 fixedly connected to the inner wall of the fixed housing 208. Multiple sets of atomizing nozzles 213 are fixedly connected to the outer surface of the water outlet pipe 212. A fixed plate 302 is fixedly connected to the upper surface of the scraper conveyor body 1. A heating housing 303 is fixedly connected to the upper surface of the fixed plate 302. Multiple sets of resistance heating rods 306 are fixedly connected to the inner wall of the heating housing 303. A blower 301 is fixedly connected to the upper surface of the heating housing 303.

[0030] Furthermore, a sliding frame 209 is slidably connected to the inner wall of the fixed housing 208. One end of the sliding frame 209 passes through the outer surface of the fixed housing 208 and is fixedly connected to a connecting plate 203. A filter plate 210 is fixedly connected to the inner wall of the sliding frame 209. The filter plate 210 is located below the fan 202. The cleaning mechanism 2 also includes a water tank 204 fixedly connected to the outer surface of the scraper conveyor body 1. A water pump 205 is fixedly connected to the upper surface of the water tank 204. The inlet of the water pump 205 extends into the interior of the water tank 204, and the outer surface of the water tank 204... The fixed connection has an observation window. The outlet of the water pump 205 is fixedly connected to a fixed pipe 206 through a pipe. The outer surface of the fixed pipe 206 is connected to one end of the outlet pipe 212. There are three sets of outlet pipes 212, which are respectively set on both sides of the rotating shaft 211. The atomizing nozzles 213 on the outer surface of the two sets of outlet pipes 212 are arranged opposite each other. The filter plate 210 is made of polytetrafluoroethylene, a breathable and hydrophobic material. The polytetrafluoroethylene filter plate 210 can still maintain good breathability and hydrophobicity, and prevent sewage from condensing on the surface.

[0031] In this embodiment, the cleaning brush 207 is driven to rotate by the servo motor 201, which can effectively clean and recycle small materials on the scraper. The PTFE filter plate 210 can prevent materials from being thrown towards the fan 202, ensuring the normal operation of the fan 202. During comprehensive cleaning, the atomizing nozzle 213 sprays water at multiple angles. Together with the water pump 205 and the fixed pipe 206, it is convenient to thoroughly clean the surface of the scraper, reduce maintenance costs, and improve the material recovery rate and equipment durability.

[0032] Reference Figures 1 to 4 In one aspect of this embodiment, a heat-conducting mesh 305 is fixedly connected to the inner wall of the heating shell 303, and the outer surface of the heat-conducting mesh 305 is attached to the outer surface of the resistance heating rod 306.

[0033] Furthermore, an air distribution plate 304 is fixedly connected to the outer surface of the fixed plate 302. The air distribution plate 304 is located below the heating shell 303, and a control panel 4 is fixedly connected to the outer surface of the scraper conveyor body 1.

[0034] In this embodiment, the drying mechanism 3 facilitates the drying of the scraper. The heat generated by the resistance heating rod 306 inside the heating shell 303 is evenly transferred through the heat conduction mesh 305. The blower 301 blows the hot air toward the air distribution plate 304, which makes the hot air evenly distributed on the surface of the scraper, accelerating the evaporation of moisture from the scraper and quickly achieving drying.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] Working Principle: When the scraper conveyor completes routine material conveying operations and requires daily cleaning, the operator activates the cleaning mechanism 2 via the control panel 4. At this time, the servo motor 201 starts working, and its output shaft drives the rotating shaft 211 to rotate, thereby causing the cleaning brush 207 fixed on the outer surface of the rotating shaft 211 to rotate as well. The rotating cleaning brush 207 directly contacts the surface of the scraper conveyor body 1 to clean the small amount of material remaining on the surface. During this process, multiple sets of fans 202 embedded in the upper surface of the fixed housing 208 start synchronously, accelerating the airflow inside the fixed housing 208 and blowing the floating material into the scraper conveyor body 1. At the same time, the filter plate 210 located below the fan 202 plays its role. Since the sliding frame 209 is slidably connected to the fixed housing 208, the filter plate 210 is stably fixed in the sliding frame 209, which can effectively block material debris that may be thrown towards the fan 202 when the cleaning brush 207 is cleaning, thus protecting the fan 202 and preventing it from being damaged by impurities.

[0037] When a lot of stubborn material accumulates on the surface of the scraper conveyor body 1 and a thorough cleaning is required, the operator first issues a thorough cleaning command through the control panel 4. The cleaning mechanism 2 and the drying mechanism 3 are started in sequence. During the cleaning stage, the water in the water tank 204 is pressurized by the water pump 205 and transported to the three sets of water outlet pipes 212 through the fixed pipe 206. Since the three sets of water outlet pipes 212 are respectively set on both sides of the rotating shaft 211 and the atomizing nozzles 213 on both sides are set opposite to each other, the pressurized water is atomized into fine water droplets through the atomizing nozzles 213 and sprayed evenly on the scraper surface from different directions to moisten and soften the stubborn material. During this process, the atomizing nozzle 213 will not become clogged. While the atomizing nozzle 213 sprays, the servo motor 201 drives the rotating shaft 211 and the cleaning brush 207 to rotate at high speed, powerfully cleaning the wetted material and ensuring that stubborn materials are thoroughly removed. During the cleaning process, the fan 202 works continuously, blowing the fine materials generated during cleaning into the interior of the scraper conveyor body 1, preventing the accumulation of materials on the surface of the cleaning brush 207. After the thorough cleaning is completed, the drying mechanism 3 starts to work. Multiple sets of resistance heating rods 306 inside the heating shell 303 are energized and heat up. The heat-conducting mesh 305 attached to the outer surface of the resistance heating rods 306 evenly transfers the heat, so that the air inside the heating shell 303 is evenly heated. Subsequently, the blower 301 starts and blows the heated air towards the air distribution plate 304 below. The air distribution plate 304 evenly distributes the hot air and blows it onto the surface of the scraper conveyor body 1, accelerating the evaporation of surface moisture and achieving rapid drying.
