[0002] Coal mine belt conveyor is an important equipment used for coal mine transportation. It is mainly used for horizontal, inclined and vertical transportation of materials such as ore and coal. The moisture content of open-pit coal mines is relatively high, up to about 35%. In winter or cold weather, the coal mine freezes and sticks to the conveyor belt of the belt conveyor. During the operation of the conveyor belt, small particles of material frozen and stuck to the bearing surface of the conveyor belt fall off due to the vibration of the belt and the friction of the rollers, forming a large amount of fallen coal in the return section of the belt.

DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0033] Refer to the following Figures 1 to 7The present invention describes an antifreeze liquid spraying device and a spraying method for a belt conveyor according to some embodiments of the present application.

[0034] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the first aspect of the present application proposes an antifreeze liquid spraying device for a belt conveyor, comprising: a support frame 110 and a spraying mechanism 120 arranged on the support frame 110, the spraying mechanism 120 comprising: a working box 121, the working box 121 having a feed port 122 and a discharge port 123 adapted to the width of the conveyor belt of the belt conveyor; a liquid storage tank 124, arranged on the working box 121, the liquid storage tank 124 storing antifreeze liquid; a plurality of liquid outlet pipes 125 , along the direction from the feed port 122 to the discharge port 123, multiple liquid outlet pipes 125 are arranged at intervals inside the working box 121; the booster pump 126 is arranged on the working box 121, the liquid inlet of the booster pump 126 is connected to the liquid storage tank 124, and the liquid outlet of the booster pump 126 is connected to the multiple liquid outlet pipes 125; multiple spray nozzles 127 are arranged at intervals at the bottom of each liquid outlet pipe 125, and the spray nozzle 127 is used to spray antifreeze spray toward the direction of the conveyor belt.

[0035] The antifreeze liquid spraying device for a belt conveyor provided in this application includes a support frame 110 and a spraying mechanism 120. The spraying mechanism 120 includes a working box 121, a liquid storage tank 124, multiple liquid outlet pipes 125, a booster pump 126, and multiple spray nozzles 127. Specifically, the feed port 122 and the discharge port 123 of the working box 121 are adapted to the width of the belt conveyor, facilitating the entry and exit of materials. This allows the antifreeze liquid to be sprayed over the entire material area on the conveyor belt, avoiding waste caused by antifreeze liquid being sprayed outside the conveyor belt, effectively improving the utilization rate of the antifreeze liquid and reducing its cost.

[0036] Multiple outlet pipes 125 are spaced apart within the working box 121, extending from the feed port 122 to the discharge port 123, to achieve wide-area spraying. Multiple spray nozzles 127 are spaced apart at the bottom of each outlet pipe 125, ensuring uniform spraying. This ensures that the antifreeze liquid is sprayed uniformly across the entire width of the conveyor belt and in the direction of material conveyance, ensuring that the material on the conveyor belt is adequately covered by the antifreeze liquid, thereby ensuring effective antifreeze protection for the material and preventing freezing of the material due to insufficient local antifreeze.

[0037] Furthermore, a booster pump 126 is provided on the working box 121. The inlet of the booster pump 126 is connected to the liquid storage tank 124, and the outlet is connected to multiple liquid outlet pipes 125. The booster pump 126 provides sufficient pressure for the antifreeze liquid, allowing it to be smoothly transported from the liquid storage tank 124 to the various liquid outlet pipes 125 and sprayed from the spray nozzles 127 at an appropriate pressure and flow rate. This ensures that the antifreeze spray effectively covers the surface of the material, improves the contact between the antifreeze liquid and the material, and enhances the antifreeze performance.

[0038] The antifreeze liquid spraying device for a belt conveyor provided in the present application is configured by arranging a plurality of liquid outlet pipes 125 at intervals and arranging a plurality of spray nozzles 127 on each liquid outlet pipe 125. This device can cover the conveyor belt of the belt conveyor over a long distance, and utilizes a booster pump 126 to provide sufficient pressure for the antifreeze liquid, thereby achieving large-scale and uniform spraying, thereby ensuring the antifreeze effect on the material and avoiding freezing of the material due to insufficient local antifreeze.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments provided in the present application, the antifreeze liquid spraying device for a belt conveyor further includes: a reflux mechanism 150, which is arranged on one side of the working box 121 close to the discharge port 123, and the reflux mechanism 150 is used to collect the antifreeze liquid spray floating inside the working box 121, and spray the collected antifreeze liquid spray toward the conveyor belt.

[0040] In this embodiment, the antifreeze liquid spraying device for a belt conveyor further includes a reflux mechanism 150. During the antifreeze liquid spraying process, some of the antifreeze liquid forms a mist that drifts within the working tank 121. The reflux mechanism 150 collects this mist, preventing it from being directly lost to the environment and instead recovering it for re-spraying toward the conveyor belt. This effectively recycles antifreeze liquid that would otherwise be wasted, reducing antifreeze liquid consumption and saving costs.

[0041] The reflux mechanism 150 sprays the collected spray onto the conveyor belt again, which increases the contact opportunity between the material and the antifreeze liquid, allowing the antifreeze liquid to adhere more fully to the surface of the material, further strengthening the antifreeze protection of the material, especially in cold environments, and can more reliably prevent the material from freezing, ensuring the normal operation of the belt conveyor.

[0042] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6As shown, in some embodiments provided in the present application, a movable hole 155 is opened on one side of the working box 121 near the discharge port 123, and the reflux mechanism 150 includes: an exhaust pipe 152, which is arranged on the side of the inside of the working box 121 near the discharge port 123; a return pipe 154, which is passed through the movable hole 155, and the return pipe 154 can slide relative to the movable hole 155, and the return pipe 154 includes an air outlet 153 facing the conveyor belt; an exhaust fan 156, which is arranged in the working box 121, and the exhaust end of the exhaust fan 156 is connected to the exhaust pipe 152, and the output end of the exhaust fan 156 is connected to the return pipe 154; an exhaust plate 158, which is arranged at the bottom of the exhaust pipe 152, and a cavity 151 is formed inside the exhaust plate 158.

[0043] In this embodiment, the reflux mechanism 150 includes an exhaust pipe 152, a return pipe 154, an exhaust fan 156, and an exhaust plate 158. The exhaust pipe 152 is located on the side of the working box 121 near the discharge port 123. The exhaust plate 158 is located at the bottom of the exhaust pipe and has a cavity 151 inside. This effectively extracts and collects antifreeze spray that drifts within the working box 121, minimizing the waste of antifreeze caused by drifting antifreeze and reducing operating costs.

[0044] The return pipe 154 is inserted through the movable hole 155 and can slide relative to the movable hole 155. Its position can be flexibly adjusted according to the actual conditions such as the conveyor belt's operating status and the material stacking height, ensuring that the collected antifreeze spray is accurately and stably returned to the appropriate position on the conveyor belt. This further enhances the antifreeze's coverage of the material and improves antifreeze performance.

[0045] The exhaust pipe 152 and return pipe 154 are located near the discharge port 123. They generally do not aspirate antifreeze spray that would normally fall on the material, nor do they hinder the normal operation of the conveyor belt, ensuring the continuous and stable operation of the belt conveyor and avoiding equipment failure or reduced conveying efficiency due to structural interference. The return pipe 154 can be a flexible hose that allows it to slide easily relative to the movable hole 155.

[0046] In actual application, the exhaust plate 158 has an air inlet facing the feed inlet 122, and the exhaust plate 158 can rotate relative to the exhaust pipe 152. The exhaust plate 158 has an air inlet facing the feed inlet 122 and can rotate relative to the exhaust pipe 152, which allows the exhaust plate 158 to flexibly adjust its angle. During the rotation process, the air inlet can cover a wider spatial area, effectively increasing the collection range of the antifreeze spray drifting in the working box 121, reducing the overflow and waste of antifreeze, and improving the recovery efficiency.

[0047] like Figure 1 and Figure 3As shown, in some embodiments provided in the present application, the reflux mechanism 150 further includes: an electric telescopic rod 159, which is arranged on the working box 121 and connected to the reflux pipe 154. When the electric telescopic rod 159 is extended or retracted, it can drive the reflux pipe 154 to slide relative to the movable hole 155 to adjust the height of the air outlet 153.

[0048] In this embodiment, the reflux mechanism 150 also includes an electrically operated telescopic rod 159. This rod is connected to the reflux tube 154. By extending and retracting, the reflux tube 154 slides within the movable hole 155, allowing for flexible adjustment of the height of the air outlet 153. The position of the air outlet 153 is precisely adjusted based on the dynamic changes in the material accumulation height on the conveyor belt, ensuring that the collected antifreeze spray is always accurately sprayed onto the material surface, thereby improving antifreeze utilization and antifreeze effectiveness.

[0049] The electric telescopic rod 159 can respond quickly under different working conditions and adjust the height of the air outlet 153, so that the device can adapt to various working scenarios without frequent manual adjustments, thereby improving the versatility and convenience of the device.

[0050] like Figure 1 As shown, in some embodiments provided in the present application, the belt conveyor antifreeze liquid spraying device also includes: a solenoid valve 160, which is arranged at the liquid outlet of the booster pump 126, for controlling the release and sealing of the antifreeze liquid; and a controller 170, which is electrically connected to the solenoid valve 160 and the electric telescopic rod 159.

[0051] In this embodiment, the antifreeze liquid spraying device for a belt conveyor further includes a solenoid valve 160 and a controller 170. Solenoid valve 160, located at the outlet of booster pump 126, precisely controls the release and containment of antifreeze liquid. It opens when spraying is required, allowing the antifreeze liquid to flow as needed; it closes when spraying is complete or no longer needed, preventing wasteful, continuous antifreeze liquid flow. This ensures precise antifreeze liquid spraying and effectively reduces operating costs.

[0052] Controller 170 is connected to electric telescopic rod 159 and can flexibly control the extension and retraction of electric telescopic rod 159 according to actual needs, thereby adjusting the height of air outlet 153 of return pipe 154. This allows the antifreeze spraying device on the belt conveyor to adapt to different material stacking heights and working conditions, ensuring that the collected antifreeze spray is accurately sprayed onto the material surface, improving the antifreeze effect.

[0053] like Figure 4 and Figure 5 As shown, in some embodiments provided in the present application, a diversion pipe 128 is provided at the bottom of each liquid outlet pipe 125, and the spraying mechanism 120 also includes: a plurality of connecting pipes 129, one end of the plurality of connecting pipes 129 is connected to the diversion pipe 128, and the other end is provided with a spray nozzle 127; wherein, the plurality of connecting pipes 129 are arranged at an angle, and the spray nozzle 127 sprays the antifreeze spray in an inclined state.

[0054] In this embodiment, the spraying mechanism 120 further includes multiple shunt pipes 128 and connecting pipes 129. Each liquid outlet pipe 125 is provided with a shunt pipe 128 at its bottom. Multiple connecting pipes 129 are connected to the shunt pipes 128 at one end and have spray nozzles 127 at the other end. After passing through the liquid outlet pipes 125, shunt pipes 128, and connecting pipes 129, the antifreeze liquid is evenly distributed to each spray nozzle 127. The inclined arrangement of the connecting pipes 129 allows the spray nozzles 127 to spray the antifreeze liquid at an angle. Compared to vertical spraying, this increases the coverage of the antifreeze liquid across the width of the conveyor belt and in the direction of material conveyance, ensuring that all parts of the material are effectively sprayed, thereby improving the comprehensiveness of the antifreeze protection.

[0055] The tilted antifreeze spray can contact the material surface at a more appropriate angle, increasing the contact area and contact time between the antifreeze and the material, allowing the antifreeze to adhere better to the material, forming a more uniform and effective antifreeze protection layer, enhancing the antifreeze effect, and reducing the risk of material freezing in cold environments.

[0056] By reasonably designing the inclination angle of the connecting pipe 129 and the distribution position of the spray nozzle 127, the antifreeze spray can be distributed more evenly in the entire spraying area, avoiding excessive or insufficient local spraying, ensuring the consistency of material antifreeze treatment, and improving the quality and stability of material transportation by the belt conveyor.

[0057] like Figure 1 As shown, in some embodiments provided in the present application, the spraying mechanism 120 further includes: a fixed plate 130, which is arranged between the working box 121 and the liquid storage tank 124, and a diversion groove 132 is opened inside the fixed plate 130; a delivery pipe 131, one end of the delivery pipe 131 is connected to the liquid outlet of the booster pump 126, and the other end of the delivery pipe 131 is connected to the diversion groove 132, and the diversion groove 132 is connected to the diversion pipe 128.

[0058] In this embodiment, the spraying mechanism 120 further includes a fixed plate 130 and a delivery pipe 131. Specifically, the fixed plate 130 is positioned between the working box 121 and the liquid storage tank 124. A diverter trough 132 is defined within the fixed plate 130. One end of the delivery pipe 131 is connected to the liquid outlet of the booster pump 126, and the other end is connected to the diverter trough 132. The diverter trough 132 is then connected to the diverter pipe 128. This ensures that the antifreeze liquid output from the booster pump 126 first enters the diverter trough 132, which provides initial buffering and even distribution of the antifreeze liquid, ensuring that the antifreeze liquid enters each diverter pipe 128 at a stable pressure and flow rate. This avoids uneven spraying caused by uneven pressure or flow rate fluctuations, and improves the stability and efficiency of antifreeze liquid delivery.

[0059] By providing the fixing plate 130 and the internal diverter groove 132, the antifreeze delivery path can be rationally integrated. The diverter groove 132 provided within the fixing plate 130 can buffer the pressure fluctuations of the antifreeze output by the booster pump 126, reducing the impact of sudden pressure changes on components such as the diverter pipe 128 and the spray nozzle 127, thereby extending the service life of these components, improving the reliability and stability of the entire spray mechanism 120, and reducing the risk of failure due to component damage.

[0060] like Figure 1 and Figure 7 As shown, in some embodiments provided in the present application, the belt conveyor antifreeze liquid spraying device further includes: a waterproof plate 180, which is arranged on the inner wall of the working box 121, and a groove 182 is opened on the waterproof plate 180, and the waterproof plate 180 is inclined toward the conveyor belt.

[0061] In this embodiment, the antifreeze liquid spraying device for a belt conveyor further includes a waterproof plate 180, which is provided with a groove 182. During the spraying process, some antifreeze liquid may drip due to gravity or the force of the spray. The inclined waterproof plate 180 guides this dripping antifreeze liquid along its surface, while the groove 182 further acts as a convergence point, collecting the antifreeze liquid and redirecting it to the conveyor belt. This prevents the antifreeze liquid from flowing freely within the working tank 121, reduces waste, and improves antifreeze liquid utilization.

[0062] The waterproof plate 180 is arranged on the inner wall of the working box 121 to prevent the dripping or splashing antifreeze from directly contacting the inner wall of the working box 121, thereby preventing the antifreeze from corroding the working box 121 and extending the service life of the working box 121.

[0063] By collecting dripping antifreeze, the waterproof plate 180 helps to keep the inside of the working box 121 clean, reduce antifreeze residue, and reduce problems such as bacteria breeding and odor caused by antifreeze accumulation, thereby creating a good internal environment for the normal operation of the device.

[0064] like Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments provided in the present application, the antifreeze liquid spraying device for a belt conveyor further includes: a machine base plate 100, the number of the machine base plates 100 is two, and the tops of the two machine base plates 100 are connected to the bottom of the support frame 110; a movable wheel 102, which is arranged below the machine base plate 100, and the movable wheel 102 includes a braking device for movement and positioning.

[0065] In this embodiment, the antifreeze liquid spraying device for a belt conveyor further includes a platform base plate 100 and movable wheels 102. By connecting two platform base plates 100 to a support frame 110 and installing movable wheels 102 underneath, the entire device is mobile. Workers can easily push the antifreeze liquid spraying device to a designated location without the need for large-scale transport equipment, significantly improving equipment deployment efficiency and reducing labor and time costs.

[0066] The movable wheel 102 is equipped with a brake device, which quickly secures the device in place once it reaches the target position. This effectively prevents the device from slipping or shifting due to external forces during the spraying operation, ensuring accurate antifreeze spraying and ensuring effective spraying. It also avoids safety accidents caused by equipment movement and provides a safe and reliable operating environment for operators.

[0067] A second aspect of the present application provides a method for spraying antifreeze fluid on a belt conveyor, comprising the following steps:

[0068] S202: moving the antifreeze spraying device of the belt conveyor to the spraying position, controlling the solenoid valve to open through the controller, and controlling the conveyor belt of the belt conveyor to start conveying materials;

[0069] S204: Controlling the boost pump to start, the antifreeze in the liquid storage tank enters the diversion pipe through the diversion groove in the fixed plate and is then sprayed out from the spray nozzle;

[0070] S206: The controller is operated to control the electric telescopic rod to extend and retract, so that the height of the electric telescopic rod and the air outlet is higher than the height of the material;

[0071] S208: Turn on the exhaust fan so that the antifreeze spray floating inside the working box is sucked away by the exhaust plate, enters the exhaust pipe, and then re-aims at the conveyor belt along the return pipe and the air outlet, and sprays the antifreeze spray on the material on the conveyor belt.

[0072] The antifreeze spraying method for a belt conveyor provided in this application first moves the antifreeze spraying device to a designated position, then opens the solenoid valve and conveyor belt, and then activates the booster pump to spray the antifreeze from the spray nozzle. This ensures that the antifreeze is sprayed promptly and accurately during material conveyance, forming an effective antifreeze protective layer and improving the accuracy and efficiency of the antifreeze spraying.

[0073] When the exhaust fan is turned on, the antifreeze spray floating inside the working box is drawn away by the exhaust plate and re-sprayed onto the material through the exhaust duct, return pipe, and outlet. This recirculation mechanism recycles the antifreeze, significantly reducing waste and production costs while also benefiting the environment. The operator controller controls the electric telescopic rod to extend and retract, raising the outlet height above the material. This can be flexibly adjusted based on the actual height of the material stack, preventing uneven spraying due to changes in material height and enhancing the antifreeze effect.

By setting five diverter pipes 128 at the same distance, large-scale spraying can be achieved, and by setting four spray nozzles 127 at the same distance on the five diverter pipes 128, uniform spraying can be achieved. The spraying mechanism 120 can cover the front end of the belt conveyor over a long distance, and the spraying range is large and the spraying is more uniform.

[0091] In addition, the antifreeze liquid spraying device and spraying method for the belt conveyor with a wide spraying range are equipped with a reflux mechanism 150. After spraying the antifreeze liquid, by observing the height of the mineral, the height of the electric telescopic rod 159 is adjusted to a height higher than the height of the transported mineral by operating the controller 170, and the exhaust fan 156 is turned on, so that the antifreeze liquid spray floating inside the working box 121 is sucked away by the exhaust plate 158, and is realigned with the conveyor belt along the reflux pipe 154 and the air outlet 153, and the antifreeze liquid spray is re-sprayed on the conveyor belt to prevent the antifreeze liquid spray from being lost along the discharge port 123.
