Abstract
Description
Technical Field
[0001] This utility model relates to the field of power plant belt conveyors, specifically to a water film pallet type belt conveyor. Background Technology
[0002] In coal-fired power plants, the transfer of coal is often accomplished using belt conveyors. Conventional belt conveyors use upper and lower idlers to support the belt, and the idlers rotate synchronously with the belt during operation.
[0003] Existing technology, such as CN212739436U, provides an all-terrain belt conveyor for open-pit mines. This conveyor includes several support sections connected by connecting plates. Each support section has several sets of trough-shaped idlers and lower idlers on its upper and lower sides. Drive rollers and redirecting rollers are located at both ends of each support section. The drive rollers are connected to a drive motor, and the redirecting rollers have tensioning structures on both sides. A conveyor belt is wound around the drive rollers, redirecting rollers, trough-shaped idlers, and lower idlers, and the conveyor belt also has a cleaning structure. Each support section has a lifting structure at its bottom. After a period of operation, the idlers in the aforementioned application require maintenance. Due to the friction between the idlers, the belt conveyor, and the idler frame, the energy consumption of the belt conveyor is significantly increased. Furthermore, the existing technology CN220998070U provides a trough-shaped idler for the receiving section of a belt conveyor, which is installed on a frame below the guide trough of the belt conveyor. This trough-shaped idler includes an idler beam detachably connected to the frame, an intermediate roller detachably and rotatably mounted in the middle of the idler beam, and side rollers detachably and rotatably mounted on the idler beam at both ends of the intermediate roller. The upper end face of the idler beam has a groove, the lower part of the intermediate roller is located within the groove, and the bottom front ends of the two side rollers are also located within the groove. It also suffers from the aforementioned technical problems.
[0004] Therefore, it is very necessary to provide a water film pallet type belt conveyor to solve the above-mentioned technical problems. Utility Model Content
[0005] Based on the above description, this utility model provides a water film pallet type belt conveyor to solve the problem that the friction between the idler rollers, the belt conveyor, and the idler roller frame in the existing idler roller structure increases the energy consumption of the belt conveyor operation.
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A water film pallet type belt conveyor includes a support frame, a belt pallet connected above the support frame, and a belt conveyor lower idler connected below the support frame. A belt is connected to the belt pallet and the belt conveyor lower idler. A water film conduit is connected to the support frame. A plurality of water outlet branch pipes are connected to the water film conduit. The water outlet end of the water outlet branch pipe is located on the side close to the belt. A water collection tank is provided below the water outlet branch pipe.
[0007] Preferably, by connecting multiple water outlet branches to the water film conduit, water spraying can be performed at multiple locations on the belt, forming a water film between the belt and the belt idler. The water film forms a lubricating layer between the belt and the idler and rollers, reducing belt wear. This extends the belt's service life, reduces the frequency and cost of belt replacement, ensures stable operation of the belt conveyor, and improves the overall reliability and availability of the equipment.
[0008] Furthermore, the support frame includes two parallel support legs and belt conveyor intermediate frames respectively connected to the two support legs. The belt conveyor lower idler is rotatably connected to the lower end of the two belt conveyor intermediate frames, the belt support plate is connected to the upper end of the two belt conveyor intermediate frames, and the water film conduit is connected to the belt support plate through the water outlet branch pipe.
[0009] Preferably, multiple parallel support legs are arranged in the direction of belt extension, providing reliable bottom support for the entire equipment and capable of withstanding the large loads generated during belt conveyor operation. A belt support plate is connected to the upper end of the intermediate frame between the two belt conveyors to support the belt and water film duct.
[0010] Furthermore, a crossbar connects the two intermediate frames of the belt conveyor, and the water collection tank is connected to the crossbar.
[0011] Furthermore, reinforcing rods are connected to the two support legs.
[0012] Furthermore, a water pipe branch is connected to one of the belt conveyor intermediate frames, the water pipe branch is connected to the water film guide pipe, and a main water pipe is connected to the support leg, the main water pipe is connected to the water pipe branch.
[0013] Preferably, the water pipe branch pipe is connected to the water film conduit, and the support leg is connected to the main water pipe and connected to the water pipe branch pipe. The main water pipe can introduce water into the equipment, while the water pipe branch pipe plays the role of diverting and accurately supplying water, ensuring that each water outlet branch pipe of the water film conduit can obtain a stable water flow.
[0014] Furthermore, the water pipe branch pipe is provided with at least one.
[0015] Furthermore, another intermediate frame of the conveyor belt is connected to a water outlet pipe, which is connected to the water collection tank.
[0016] Furthermore, a drainage channel is provided at the lower end of the water outlet pipe.
[0017] Furthermore, the water outlet pipe is provided with at least one.
[0018] Furthermore, the belt support plate is arranged in an inverted trapezoidal shape, and the shape of the water film conduit corresponds to the shape of the belt support plate.
[0019] Preferably, the belt support plate is arranged in an inverted trapezoidal shape. When water is sprayed out from the water film conduit through the outlet branch pipe, the water flow can flow and spread evenly along the inclined side of the inverted trapezoid because the shape of the water film conduit is adapted to the belt support plate, ensuring that the water film can fully and evenly cover the belt surface. At the same time, it also facilitates the collection of water into the water collection tank.
[0020] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: By connecting multiple water outlet branches to the water film conduit, water can be sprayed onto the belt at multiple locations, creating a water film between the belt and the belt idler. This water film forms a lubricating layer between the belt and the idler / roller, reducing belt wear. This extends the belt's service life, reduces the frequency and cost of belt replacement, ensures stable operation of the belt conveyor, and improves the overall reliability and availability of the equipment. It also solves the problem of increased energy consumption during belt conveyor operation due to friction between the idler / roller structure, the belt conveyor, and the idler frame in existing technologies.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] like Figures 1 to 2As shown, a water film pallet type belt conveyor includes a support frame 1, a belt pallet 2 connected above the support frame 1, and a belt conveyor lower idler 3 connected below the support frame 1. A belt 4 is connected to the belt pallet 2 and the belt conveyor lower idler 3. A water film conduit 5 is connected to the support frame 1. A plurality of water outlet branch pipes 51 are connected to the water film conduit 5. The water outlet end of the water outlet branch pipe 51 is located on the side close to the belt 4. A water collection tank 6 is provided below the water outlet branch pipe 51.
[0025] In this embodiment, the support frame 1 supports the upper belt tray 2 and the lower belt conveyor roller 3. The support frame can be welded or bolted together to maintain the overall stability of the structure. The belt tray 2 is fixedly connected to the upper part of the support frame 1, and the lower belt conveyor roller 3 is rotatably connected to the lower part of the support frame 1. The lower belt conveyor roller 3 cooperates with the belt tray 2 to provide stable support for the belt 4. The output end of the drive motor is rotatably connected to the corresponding lower belt conveyor roller 3 to drive the belt 4. The belt 4 is a ring-shaped assembly fitted onto the belt tray 2 and the lower belt conveyor roller 3, used to carry and transport materials such as ore, grain, and waste.
[0026] Additionally, the water film conduit 5 is fixed to the support frame 1, located to the side of the belt support plate 2, to deliver water to each outlet branch pipe 51.

The water outlet end of the outlet branch pipe 51 is 5-20mm away from the surface of the belt 4, and the number is set according to the width of the belt 4, such as one every 10-15cm. During operation, water is sprayed out from the outlet branch pipe 51, forming a continuous water film on the surface of the belt 4 to effectively reduce the friction between the belt 4 and the belt support plate 2. The water collection tank 6 is located directly below the outlet branch pipe 51, with its opening facing upwards, to collect water dripping from the surface of the belt 4, preventing wastewater from directly contaminating the equipment or the ground.
[0027] Meanwhile, since the material falling on the belt 4 will cause the belt to vibrate, by setting a water film between the belt 4 and the belt support plate 2, the water film can absorb energy and lubricate to a certain extent, thereby greatly reducing the friction between the belt 4 and the belt support plate 2, thus improving the service life of the belt, reducing the replacement frequency of the belt 4, and thus reducing the replacement cost of the belt 4.
[0028] In some embodiments, the support frame 1 includes two parallel support legs 11 and belt conveyor intermediate frames 12 respectively connected to the two support legs 11. The belt conveyor lower idler roller 3 is rotatably connected to the lower end of the two belt conveyor intermediate frames 12.

[0029] In this embodiment, the support frame 1 consists of several parallel and spaced support legs 11, which can be made of square steel or channel steel and placed perpendicular to the ground. In addition, the bottom of the support legs 11 can be provided with foot plates to enhance the stability of the structure. The intermediate frame 12 of the belt conveyor is vertically fixed between two support legs 11.
[0030] The lower idler roller 3 of the belt conveyor has two ends rotatably connected to the lower ends of the two intermediate frames 12 of the belt conveyor via bearing seats. The axis of the lower idler roller 3 is perpendicular to the length direction of the intermediate frame 12 and rotates synchronously with the belt 4. The belt support plate 2 is fixedly connected to the upper end face of the two intermediate frames 12 of the belt conveyor by bolts or welding. The belt support plate 2 is arranged parallel to the lower idler roller 3 to form a stable support for the belt 4.
[0031] In addition, the water film conduit 5 is indirectly fixed to the belt support plate 2 through several water outlet branch pipes 51, and the water outlet end of the water outlet branch pipe 51 is always aligned with the upper surface of the belt 4.
[0032] In some embodiments, a crossbar 13 is connected between the two belt conveyor intermediate frames 12, and the water collection tank 6 is connected to the crossbar 13.
[0033] In this embodiment, a crossbar 13 is connected between the intermediate frames 12 of the two belt conveyors, which can increase the stability of the entire structure and also support the water collection tank 6.
[0034] In some embodiments, reinforcing rods 14 are connected to the two support legs 11.
[0035] In this embodiment, a reinforcing rod 14 is connected between the two support legs 11 to increase the stability of the support legs 11.

[0037] In this embodiment, a water pipe branch 71 is fixedly connected to the side of one of the belt conveyor intermediate frames 12 via pipe clamps or brackets. The water pipe branch 71 can be made of PVC pipe or metal pipe, and the pipe diameter can be adjusted according to the water inlet requirements of the water film conduit 5. One end of the water pipe branch 71 is connected to the water inlet of the water film conduit 5 via a connector, such as a threaded connector or a quick-connect connector, to form a complete water flow channel.
[0038] Meanwhile, the main water pipe 7 is fixedly connected to the side of the support leg 11 by clamps or welding brackets. One end of the main water pipe 7 can be connected to an external water source, such as a water pump or a main water pipe, and the other end is sealed to the end of the water pipe branch pipe 71 away from the water film conduit 5 by a tee or direct connection.
[0039] In some embodiments, the water pipe branch 71 is provided with at least one.

[0047] In some embodiments, the belt support plate 2 is arranged in an inverted trapezoidal shape, and the shape of the water film conduit 5 corresponds to the shape of the belt support plate 2.
[0048] In this embodiment, the shape of the water film conduit 5 corresponds to the shape of the belt support plate 2, so that the water outlet branch pipe 51 can better spray water onto the belt 4. Furthermore, its inverted trapezoidal shape allows the water on the belt 4 to fall more effectively into the water collection tank 6 under the influence of gravity.
