Description

Technical Field

[0001] The utility model belongs to the technical field of material cleaning and relates to a belt surface cleaning system for a belt conveyor. Background Art

[0002] The return belt surface of a belt conveyor refers to the part of the conveyor belt that carries materials and returns after completing the carrying section.

[0003] In the cleaning and environmental protection process of raw material units in the iron and steel metallurgical industry, it is easy for a large amount of material to fall and scatter along the conveying corridor when the belt conveyor returns, polluting the environment along the way and requiring a lot of manpower to clean up.

[0004] In the existing belt conveyor belt return, the traditional alloy or polyurethane cleaner is usually used to clean the material, and the scraper of the cleaner is used to contact the belt surface to scrape the material. However, after a period of operation, the scraper is worn due to long-term contact and friction with the belt surface, resulting in poor cleaning effect. Therefore, in the process of seeking a better cleaning method, some technicians proposed to use water cleaning to clean the return belt surface of the belt conveyor, and designed and manufactured nozzle-type and water jet-type cleaning devices.

[0005] When the belt conveyor belt surface is cleaned by water flushing, there is also a problem of high water consumption during use, resulting in a waste of water resources. At the same time, excessive water is introduced during the cleaning process, resulting in a large amount of water on the belt conveyor belt surface, causing sewage pollution to the subsequent transportation environment. The moisture content in the material is also increased due to the introduction of too much cleaning water, which in turn affects the subsequent production process. In addition, additional facilities and equipment such as sewage collection, filtration, and sedimentation are required, which not only takes up too much production space, but also increases operating costs, making it difficult to achieve large-scale industrial applications.

The cleaned materials fall directly into the funnel, which will not cause secondary pollution to the subsequently transported materials, thus avoiding the impact on the subsequent production process. It can also be placed along the conveying route of the belt conveyor according to actual needs to play the role of cleaning along the way.

[0037] The belt conveyor belt surface 2 cleaning system includes a flow regulating device 3 and a cleaning device 6, which are connected to each other through a connecting device 5; a water supply device 4 is also provided at one end of the flow regulating device 3 away from the connecting device 5, and the water supply device 4 is connected in series with the flow regulating device 3 through a water supply line. The flow regulating device 3 is used to adjust the water pressure from the water supply device 4, and then transport the water to the cleaning device 6 through the connecting device 5, and the water then flows out of the cleaning device 6 to clean the return belt surface 2 of the belt conveyor. The flow regulating device 3 and the water supply device 4 are both arranged on the base 1.

[0038] The water supply device 4 includes a water supply pump 41 , which is respectively connected to the high-pressure pressurizing device 32 and the low-pressure pressurizing device 33 ; and also includes a water inlet 42 arranged on the water supply pump 41 .

[0039] The flow regulating device 3 includes a high-pressure pressurizing device 32 and a low-pressure pressurizing device 33 connected in parallel.

The water in the water supply device 4 first flows through the first filter assembly 322, and the filtered water flow is then pressurized by the centrifugal pump to adjust the output flow and pressure of the water flow.

The water in the water supply device 4 first flows through the second filter assembly 332, and the filtered water flow is then pressurized by the centrifugal pump to adjust the output flow and pressure of the water flow.

[0042] The first filter component 322 and the second filter component 332 are used to filter out impurities in the water; the centrifugal pump can control the flow rate and pressure of the water output through frequency conversion regulation, and the high-pressure pressurizing device 32 and the low-pressure pressurizing device 33 can be automatically or manually switched according to actual working conditions.

[0043] The pressure regulating device 31 includes a motor 311 and a control box 312 electrically connected to the motor 311. The motor 311 is a variable frequency regulating motor. The water pressure in the high-pressure pump 321 is 1-20 MPa, which can be gradually adjusted by the motor 311; the water pressure in the low-pressure pump 331 is about 1 MPa or less, which is a fixed water pressure, determined according to the selected low-pressure pump 331, and cannot be adjusted. It is usually the minimum water pressure for washing the belt surface 2 of the belt conveyor. The control box 312 can manually control the start and stop of the high-pressure pump 321 beside the machine, adjust the flow pressure of the water, and monitor the operating status of the pump to ensure the safe operation of the pump.

[0044] The connecting device 5 includes a first water channel 51 and a second water channel 52 and a third water channel 53 respectively connected in series with the first water channel 51. The second water channel 52 and the third water channel 53 are arranged in parallel. One end of the first water channel 51 is connected to the cleaning device 6, and the other end is respectively connected to the second water channel 52 and the third water channel 53. The high-pressure pump 321 is connected to the end of the second water channel 52 away from the first water channel 51, and the low-pressure pump 331 is connected to the end of the third water channel 53 away from the first water channel 51. The first water channel 51, the second water channel 52 and the third water channel 53 are all composed of a combination of a hose and a hard pipe.

[0045] The flow regulating device 3 further includes a regulating valve 34, which includes a one-way valve and a switching valve arranged in series. The one-way valve and the switching valve are respectively arranged in series in the middle of the second water channel 52 and the third water channel 53. The one-way valve and the switching valve control the water flow and opening and closing of the second water channel 52 and the third water channel 53 to realize the selection of high pressure or low pressure for the cleaning water. The switching valve is a manual or electric switching valve.

[0046] The one-way valve in this embodiment controls the flow direction of water in the connecting device 5. In the hydraulic system, the main function of the one-way valve is to control the flow direction of the liquid, allowing the liquid to flow from the high-pressure end to the low-pressure end, and prohibiting the liquid from flowing from the low-pressure end to the high-pressure end; when the liquid pressure in the hydraulic system reaches a certain value, the valve core of the high-pressure hydraulic one-way valve will be opened by the pressure, and the liquid can flow from the high-pressure end to the low-pressure end. When the liquid pressure decreases, the spring will push the valve core to close, thereby preventing the liquid from flowing in the opposite direction. In this embodiment, the one-way valve only allows water to flow from the high-pressure pump 321 or the low-pressure pump 331 to the cleaning device 6, and prohibits water from flowing from the cleaning device 6 to the high-pressure pump 321 or the low-pressure pump 331.

[0047] The one-way valve effectively prevents the backflow of the fluid. Without the need for external control, it automatically adjusts the flow direction of the fluid according to the pressure difference, thus realizing the automation of fluid control.

[0048] The switching valve is used to switch the water flow in the second water channel 52 and the third water channel 53 to different water pressures.

[0049] Through the cooperation of each device in the flow regulating device 3, the flow rate and water pressure of the cleaning water in the device can be adjusted to the most suitable state, so as to realize the high and low pressure regulation and conversion of the cleaning water pressure. Taking the bandwidth of 1200mm as an example, the water pressure of the cleaning water can be adjusted to more than 10MPa at the maximum and 1MPa at the minimum, and the flow rate can be controlled at 1m 3 / h or so.

[0050] The cleaning device 6 includes a cleaning component 61 and a scraping component 62.

The nozzles 612 face the return belt surface 2 of the belt conveyor. The water flowing into the cleaning device 6 is sprayed out through the nozzles 612 and sprayed on the belt surface 2, thereby cleaning the belt surface 2. The orientation angles of the water pipe 611 and the nozzles 612 can be adjusted according to actual needs to facilitate the multi-directional spraying work. The water spraying range of the nozzle 612 covers the width direction of the belt surface 2 of the belt conveyor, wherein the width direction of the belt surface 2 is the direction of the belt surface 2 running vertically on the belt surface 2, thereby avoiding cleaning dead corners; the angle between the water spraying direction of the nozzle 612 and the belt surface 2 is less than 90 degrees, and the lateral water flow is sprayed on the belt surface 2, which can exert a stronger water flow impact force, and the cleaning effect on the belt surface 2 is more significant, and the nozzle 612 is arranged laterally relative to the belt surface 2, which can also prevent the material cleaned from the belt surface 2 from falling directly onto the nozzle 612, causing the nozzle 612 to be blocked.

[0051] The scraping assembly 62 is arranged on one side of the cleaning assembly 61, and can scrape and clean the belt surface 2, and scrape away the sewage stains remaining on the belt surface 2. The scraping assembly 62 and the cleaning assembly 61 are used together to achieve a better cleaning effect. In actual working conditions, multiple combinations can also be made according to the on-site conditions to meet different needs.
