Abstract
Description
Technical Field
[0001] This utility model belongs to the field of belt cleaning technology for belt conveyors, and particularly relates to a self-cleaning device for belt conveyor transmission belts. Background Technology
[0002] A belt conveyor is a conveying device used to transport materials. Its main structure includes a frame and a transmission belt mounted on the frame. During operation, the transmission belt in the transmission state transports the materials.
[0003] Since belt conveyors are used to transport materials year-round, a large amount of dirt tends to accumulate on them after a period of time. If materials that require a certain level of cleanliness, such as food, are transported via the belt conveyor, the dirt adhering to the belt can easily contaminate the materials.
[0004] Therefore, the belt needs to be cleaned regularly. The current cleaning method is to install nozzles on the frame of the belt conveyor to spray cleaning agent onto the belt, and rely on the cleaning agent sprayed by the nozzles at a certain pressure to flush away the dirt.
[0005] However, the drawback of this cleaning method is that it is difficult to remove stubborn dirt by simply spraying it.
[0006] Furthermore, since the surface of the belt is not a flat structure, the cleaning agent sprayed on it tends to adhere to the uneven structure, such as the raised structure (the belt surface is roughened to form a rough raised structure to increase the friction between it and the material). After spraying, the dirt dissolved in the adhering cleaning agent is difficult to fall off the belt, so the cleaning effect is not ideal for belts with a lot of dirt.
[0007] This results in a large amount of cleaning agent being needed during actual work, and dealing with the large amount of cleaning agent flowing onto the workshop floor is also quite troublesome. Utility Model Content
[0008] Based on the above background, the purpose of this utility model is to provide a self-cleaning device for belt conveyors.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] A self-cleaning device for a belt conveyor includes several cleaning units for cleaning the conveyor belt, wherein the cleaning units are installed on the frame of the belt conveyor along the length of the conveyor belt.
[0011] The cleaning unit includes swing brackets hinged to both sides of the frame, and a drying cleaning mechanism and a humidity cleaning mechanism are respectively assembled and connected to both ends of the swing brackets.
[0012] The two sides of the swing bracket are respectively hinged with a push structure. The push structure pushes the swing bracket to swing to the drying and cleaning mechanism or the humidity cleaning mechanism to contact the transmission belt for drying and cleaning or humidity cleaning.
[0013] The swing bracket is also equipped with a first spraying mechanism and a second spraying mechanism that cooperate with the humidity cleaning mechanism. The first spraying mechanism is used to spray cleaning agent onto the conveyor belt, and the second spraying mechanism is used to spray cleaning agent onto the humidity cleaning mechanism.
[0014] Preferably, the longitudinal cross-sectional shape of the swing bracket is a V-shaped structure, and the lower end of the swing bracket is hinged to a lower hinge support, which is fixedly installed at the top of the frame.
[0015] Preferably, a drying and cleaning mechanism is installed on the upper front side of the swing bracket, and a humidity cleaning mechanism is installed on the upper rear side of the swing bracket.
[0016] Preferably, the drying and cleaning mechanism includes a drying and cleaning cylinder support, on which drying and cleaning brush bristles are fixedly connected;
[0017] The humidity cleaning mechanism includes a humidity cleaning cylinder support, on which humidity cleaning brush bristles are fixedly connected.
[0018] Preferably, both ends of the drying cleaning cylinder support and the humidity cleaning cylinder support are detachably mounted with U-shaped supports, and the U-shaped supports are respectively fixedly connected with rotating shafts that are rotatably connected to the swing support;
[0019] The upper ends of the swing bracket are respectively fixedly installed with drive motors on both sides, and the output shafts of the drive motors are fixedly installed on the rotating shaft.
[0020] Preferably, the pushing structure includes an electric push rod, the telescopic end of which is fixedly connected to a push rod, the end of which is fixedly connected to a push hinge seat, and a pin of the hinge push hinge seat is fixedly connected to the swing bracket;
[0021] The bottom of the electric push rod is hinged to a bottom hinge seat, which is fixedly installed on the top of the frame.
[0022] Preferably, the bottom of the electric push rod is fixedly connected to an ear seat, which is hinged to the bottom hinge seat by a pin.
[0023] Preferably, the first spraying mechanism includes a first spray pipe fixedly installed between the rear sides of the swing bracket, and a plurality of first nozzles with the spraying direction facing the conveyor belt are installed on the first spray pipe.
[0024] The second spraying mechanism includes a second spray pipe fixedly installed between the front sides of the swing bracket, and a plurality of second nozzles with the spray direction facing the humidity cleaning cylinder bracket are installed on the second spray pipe.
[0025] Preferably, the first nozzle and the second nozzle are threadedly connected to the swing bracket;
[0026] The inlet ends of the first and second nozzles are connected to the pump cleaning agent pipeline via flexible connecting pipes.
[0027] This utility model has the following beneficial effects:
[0028] 1. During the cleaning process, the transmission belt is first cleaned by a humidity cleaning mechanism. Specifically, the first and second spray cleaning mechanisms spray cleaning agent onto the belt, and then the humidity cleaning mechanism cleans it by rotating rollers. This method aims to remove stubborn dirt (such as dirt on the raised structures of the belt).
[0029] After passing through the humidity cleaning mechanism, most of the wastewater on the belt falls off during the belt's transmission process (such as when it reaches the bottom). However, some wastewater stains adhere to the rough, raised structures, so the dry cleaning mechanism is switched on. This mechanism uses a dry rotating roller to wipe away the stubborn wastewater stains. Simultaneously, the humidity cleaning process dries the belt, ensuring it dries completely in a short time.
[0030] 2. During operation, when it is necessary to flip and lower the drying and cleaning cylinder support to be close to the belt, the front pushing structure pulls the swing support forward and flips it forward. Correspondingly, the rear pushing structure pushes the swing support forward, so as to cooperate with the front pushing structure.
[0031] Similarly, when the rear of the swing support needs to be flipped, the front pushing structure pushes backward and the rear pushing structure pulls backward.
[0032] 3. During operation, the first nozzle sprays cleaning agent downwards onto the belt, softening the dirt and allowing it to be removed by the humidity cleaning mechanism. However, because a large amount of dirt adheres to the humidity cleaning brushes of the mechanism during cleaning, re-cleaning these brushes while the belt is in motion can easily lead to secondary contamination. Therefore, a second nozzle sprays cleaning agent directly onto the humidity cleaning brushes (which have stiff bristles that are easily detached from the dirt during spraying) to clean the brushes. This method enhances the cleaning effect. Attached Figure Description

[0043] Example 1
[0044] like Figure 1-5 As shown, a self-cleaning device for a belt conveyor includes several cleaning units 1 for cleaning the conveyor belt. The cleaning units 1 are mounted on the frame of the belt conveyor (not shown) along the length of the conveyor belt. The multiple cleaning units 1 achieve thorough cleaning of the conveyor belt.
[0045] Specifically, the cleaning unit 1 includes swing brackets 11 (in V-shape) respectively hinged to both sides of the frame (i.e., the frame of the belt conveyor). The hinge method is as follows: the lower end of the swing bracket 11 is fixedly connected to a pin, and the pin is hinged to a lower hinge support 111, which is fixedly installed at the top of the frame.
[0046] Drying and cleaning mechanism 12 and humidity cleaning mechanism 13 are respectively installed and connected at both ends of the swing bracket 11.
[0047] Specifically, a drying and cleaning mechanism 12 is installed on the upper front side of the swing bracket 11, and a humidity cleaning mechanism 13 is installed on the upper rear side of the swing bracket 11.
[0048] In this cleaning process, the transmission belt is first cleaned by the humidity cleaning mechanism 13. Specifically, the first and second spray cleaning mechanisms spray cleaning agent onto the belt, and then the humidity cleaning mechanism 13 cleans it by rotating roller wiping. This method aims to remove stubborn dirt (such as dirt on the raised structures on the belt).
[0049] After passing through the humidity cleaning mechanism 13, most of the sewage on the belt falls off during the belt transmission process (such as when it is driven to the bottom position). However, some sewage stains are attached to the rough raised structure. Therefore, the dry cleaning mechanism 12 is switched on, and the dry rotating roller of the dry cleaning mechanism 12 is used to clean the sewage stains that are difficult to remove.
[0050] At the same time, the belt is dried after being cleaned by the drying and cleaning mechanism 12, so that the belt can be completely dried in a short time.
[0051] Example 2
[0052] like Figure 1-5 As shown, based on the structure of Embodiment 1, the above-mentioned drying and cleaning mechanism 12 includes a drying and cleaning cylinder support 121, and drying and cleaning brush bristles 122 (nylon bristles) are fixedly connected to the drying and cleaning cylinder support 121.
[0053] Similarly, the humidity cleaning mechanism 13 includes a humidity cleaning cylinder support 131, on which a humidity cleaning brush bristle 132 (preferably using fiber bristles with slightly higher hardness, which is used to clean dirt with strong adhesion) is fixedly connected.
[0054] The dry cleaning cylinder support 121 and the humidity cleaning cylinder support 131 are respectively equipped with U-shaped brackets 15 at both ends (the U-shaped brackets 15 are fixed by bolts for easy disassembly and cleaning), and the U-shaped brackets 15 are respectively fixedly connected with rotating shafts that are rotatably connected to the swing bracket 11.
[0055] Meanwhile, drive motors 14 are fixedly installed on both sides of the upper end of the swing bracket 11. According to the existing method, the output shaft of the drive motor 14 is fixedly installed on the rotating shaft, such as by a coupling.
[0056] During operation, the drying cleaning cylinder support 121 and the humidity cleaning cylinder support 131 rotate at high speed under the drive of the motor to treat the belt by rotating roller rubbing.
[0057] Example 3
[0058] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, in order to facilitate the switching between the dry cleaning cylinder support 121 and the humidity cleaning cylinder support 131, the front and rear sides of the swing support 11 are respectively hinged with a push structure 16. The push structure 16 pushes the swing support 11 to swing to the dry cleaning mechanism 12 or the humidity cleaning mechanism 13 to abut against the transmission belt for dry cleaning and humidity cleaning.
[0059] Specifically, when it is necessary to flip and lower the drying and cleaning cylinder bracket 121 to be close to the belt, the front pushing structure 16 pulls the swing bracket 11 forward and flips it forward. Correspondingly, the rear pushing structure 16 pushes the swing bracket 11 forward, so as to cooperate with the front pushing structure 16.
[0060] Similarly, when the swing bracket 11 needs to be flipped over, the front pushing structure 16 pushes backward and the rear pushing structure 16 pulls backward.
[0061] Specifically, the pushing structure 16 includes an electric push rod 161 (the electric push rod 161 is a conventional electric push rod 161 disclosed in the prior art), the telescopic end of the electric push rod 161 is fixedly connected to a push rod 163, the end of the push rod 163 is fixedly connected to a push hinge seat 164, and a pin is fixedly connected to the rocker bracket 11 to the hinge push hinge seat 164; the bottom of the electric push rod 161 is hinged to a bottom hinge seat 162, and the bottom hinge seat 162 is fixedly installed on the top of the frame.
[0062] Meanwhile, the bottom of the electric push rod 161 is fixedly connected to an ear seat, which is hinged to the bottom hinge seat 162 by a pin.
[0063] During the extension and retraction of the electric push rod 161, the swing bracket 11 is pushed.
[0064] Example 4
[0065] like Figure 1-5 As shown, in order to achieve thorough cleaning of the conveyor belt, the swing bracket 11 is further equipped with a first spraying mechanism and a second spraying mechanism that cooperate with the humidity cleaning mechanism 13. The first spraying mechanism is used to spray cleaning agent onto the conveyor belt, and the second spraying mechanism is used to spray cleaning agent onto the humidity cleaning mechanism 13.
[0066] The first spraying mechanism includes a first spray pipe 17 fixedly installed between the rear sides of the swing bracket 11, and a plurality of first nozzles 171 with the spray direction facing the conveyor belt are installed on the first spray pipe 17; the second spraying mechanism includes a second spray pipe 18 fixedly installed between the front sides of the swing bracket 11, and a plurality of second nozzles 181 with the spray direction facing the humidity cleaning cylinder bracket 131 are installed on the second spray pipe 18.
[0067] The first nozzle 171 and the second nozzle 182 are conventional nozzles disclosed in the prior art, used to spray out cleaning agents.
[0068] Meanwhile, in order to coordinate with the swinging motion of the swing bracket 11, the liquid inlet positions of the first nozzle 17 and the second nozzle 18 are respectively connected to the pump cleaning agent pipeline through flexible connecting pipes.
[0069] During operation, the first nozzle 171 sprays the cleaning agent downwards onto the belt, softening the dirt on the belt, which is then cleaned by the humidity cleaning mechanism 13. However, during the cleaning process, a large amount of dirt adheres to the humidity cleaning bristles 132 on the humidity cleaning mechanism 13. This can easily lead to secondary contamination of the belt if the humidity cleaning bristles 132 with dirt adhering to them are cleaned again during belt movement. Therefore, the second nozzle 182 sprays the cleaning agent onto the humidity cleaning bristles 132 on the humidity cleaning mechanism 13 to clean the humidity cleaning bristles 132 (which are hard bristles that are easily detached from the dirt during the spraying process).
[0070] The above methods can be used to enhance the cleaning effect.
[0071] The first nozzle 17 and the second nozzle 18 are threadedly connected to the swing bracket 11. Specifically, the outer walls of the first nozzle 17 and the second nozzle 18 are provided with threaded structures, which are intended to facilitate the adjustment of the angle of the corresponding nozzles after rotating the first nozzle 17 and the second nozzle 18 through the threaded connection.
[0072] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
