Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically to an automatic cleaning device for belt conveyor corridors. Background Technology

[0002] Belt conveyors, as a type of solid material conveying equipment with low operating costs, high conveying efficiency, safety, reliability, and continuous operation, are indispensable in many fields involving material handling. They are widely used in industries such as metallurgy, coal, transportation, power, building materials, chemicals, light industry, grain, and machinery. With economic development and social progress, both domestically and internationally, the requirements for factory production environments and workers' working environments are becoming increasingly stringent. Traditional corridor-type conveyors, mostly composed of cement civil engineering or large steel structure trestle bridges, cannot be quickly cleaned in harsh conveying environments, failing to meet current industry environmental protection needs.

[0003] For example, patent publication number CN 207267672 U discloses a modular corridor belt conveyor, including a corridor and a belt conveyor installed within the corridor. The corridor includes legs, a base plate, side plates, and a transparent skylight. The legs are connected to the lower part of the base plate, the side plates are connected to both sides of the base plate, and the transparent skylight is connected to the top of the side plates. The base plate, side plates, and transparent skylight enclose the corridor to form a sealed corridor. The base plate, side plates, and transparent skylight are respectively formed by connecting base plate modules, side plate modules, and skylight modules. The base plate modules, side plate modules, and skylight modules have fixed lengths. The corridor of this corridor belt conveyor is formed by connecting corridor module sections, resulting in a short on-site installation cycle. Furthermore, since each corridor module section has the same length, different corridor module sections can be interchanged.

[0004] The aforementioned patent still has some problems in use. Sealing the corridor can improve the environment, but it still cannot achieve the purpose of cleaning. The transparent skylights will also be quickly covered by dust and are prone to damage during long-term use. Sealing the corridor is not as good as cleaning the corridor directly, which can ensure the cleanliness of the corridor and also recycle the dust. Therefore, there is now a need for an automatic corridor cleaning device with a belt conveyor. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic cleaning device for belt conveyor corridors. This device uses high-pressure nozzles to spray high-pressure water jets to lift the cover plates and clean the walking ramps. It also uses a filter box to filter and recycle the wastewater, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic cleaning device for a belt conveyor corridor, comprising a water tank and a walking ramp. Two sets of support seats are fitted together on the left and right sides of the water tank. A feeding belt is respectively arranged on the upper part of the two sets of support seats. Several sets of high-pressure nozzles are equidistantly connected on the upper part of the water tank. A protective shell is fixedly installed on the outer surface of the water tank outside the high-pressure nozzles. The walking ramp is fitted together on the outside of the water tank, and a standing plate is arranged on the walking ramp corresponding to the position of the protective shell. A cover plate is rotatably installed on the front side of the standing plate.

[0007] A filter box is installed at the bottom of the water tank, and several sets of water pumps are connected and installed at the top of the filter box.

[0008] Preferably, a groove is provided in the middle of the upper surface of the water tank, and a water supply pipe is provided inside the groove. The water supply pipe is connected to a high-pressure nozzle, and a discharge port is provided on the lower side of the water tank.

[0009] Preferably, protective frames are symmetrically fitted on the left and right sides of the walking ramp, a footboard is installed at the bottom of the walking ramp, a cavity is provided under the footboard, the discharge port is connected to the cavity, and a handrail is installed on the outside of the protective frame corresponding to the footboard position.

[0010] Preferably, the filter box has a feed inlet installed on the front side, the feed inlet is inserted into the inner wall of the discharge port, and the opening of the feed inlet extends into the cavity below the pedal.

[0011] Preferably, the filter box is equipped with a filter screen inside, and a sealing back plate is installed on the rear side of the filter box.

[0012] Preferably, a protective support frame is bolted to the upper part of the filter box, and several sets of water pumps are located inside the protective support frame. The water pump input end is provided with an inlet pipe, and the end of the inlet pipe is located below the filter screen. The water pump output end is provided with an outlet pipe, and the outlet pipe is sealed and connected to the water delivery pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Water is stored in a water tank and sprayed out through high-pressure nozzles to wash the ramp. A protective shell and a standing plate are installed to protect the high-pressure nozzles and allow workers to stand up when dismantling the platform. A cover plate installed on the front of the standing plate is used to block the water jet from the high-pressure nozzle. When the water pressure is constant, the water jet will push the cover plate up. By rotating the cover plate, the cleaning position of the water jet can be changed, thereby increasing the cleaning range of the ramp.

[0015] 2. After flushing the walking ramp, the wastewater flows down the inclined walking ramp to the underside of the pedal and enters the filter box through the feed inlet to complete the filtration. The filter screen inside the filter box can filter impurities in the water, so that the clean water is located under the filter screen. The water is then pumped into the water tank for use through the water pump input end, thus completing the flushing of the walking ramp while reducing the waste of water resources.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] This invention provides: an automatic cleaning device for belt conveyor corridors, such as... Figure 1-5 As shown, the system includes a water tank 3 and a walking ramp 8. Two sets of support seats 1 are installed on the left and right sides of the water tank 3. A feeding belt 2 is installed on the upper part of each of the two sets of support seats 1. Several sets of high-pressure nozzles 6 are installed at equal intervals on the upper part of the water tank 3. A protective shell 5 is fixedly installed on the outer surface of the water tank 3 outside the high-pressure nozzles 6. The walking ramp 8 is installed on the outer side of the water tank 3, and a standing plate 9 is set on the walking ramp 8 corresponding to the position of the protective shell 5. A cover plate 10 is rotatably installed on the front side of the standing plate 9. A filter box 14 is set at the lower part of the water tank 3. Several sets of water pumps 19 are installed on the upper part of the filter box 14.

[0024] Preferably, a groove is provided in the middle of the upper surface of the water tank 3, and a water supply pipe 4 is provided inside the groove. The water supply pipe 4 is connected to a high-pressure nozzle 6. A discharge port 13 is provided on the lower side of the water tank 3. The groove in the upper part of the water tank 3 is used to store the water supply pipe 4, and the water supply pipe 4 is used to connect the various high-pressure nozzles 6 in series. The operation of the high-pressure nozzles 6 ensures that water is sprayed out to flush and clean the walking ramp 8.

[0025] Furthermore, protective frames 7 are symmetrically installed on both sides of the walking ramp 8, and a footboard 11 is installed at the bottom of the walking ramp 8. A cavity is provided on the lower side of the footboard 11, and the discharge port 13 is connected to the cavity. A handrail 12 is installed on the outer side of the protective frame 7 corresponding to the footboard 11. The protective frames 7 on both sides of the walking ramp 8 improve the safety of the walking ramp 8 and limit the flow of water sprayed from the high-pressure nozzle 6, so that the flushing waste liquid can flow more stably to the lower part of the footboard 11 and enter the discharge port 13. The footboard 11 and handrail 12 allow the staff to stand stably. The cavity at the lower part of the footboard 11 is connected to the discharge port 13, and the footboard 11 is not attached to the walking ramp 8, so that the waste liquid can flow quickly into the cavity.

[0026] Furthermore, a feed inlet 15 is connected to the front of the filter box 14. The feed inlet 15 is inserted into the inner wall of the discharge port 13. The opening at the front of the feed inlet 15 extends into the lower cavity of the pedal 11. The feed inlet 15 on the front of the filter box 14 is inserted into the discharge port 13, which ensures that the device can quickly collect waste liquid into the filter box 14 for filtration, so as to meet the recycling of waste liquid and reduce the waste of water resources.

[0027] It is worth noting that a filter screen 16 is installed inside the filter box 14, and a sealing back plate 17 is installed on the rear side of the filter box 14. The filter screen 16 inside the filter box 14 can separate waste material and waste liquid after the waste liquid is flushed into the filter box 14, so that the waste liquid is filtered out to the underside of the filter screen 16. The sealing back plate 17 is sealed to the filter box 14, which can effectively seal the rear side of the filter box 14. At the same time, the gap can be used to clean the waste residue filtered out inside the filter box 14.

[0028] Specifically, a protective support frame 18 is bolted to the upper part of the filter box 14. Several sets of water pumps 19 are located inside the protective support frame 18. The input end of the water pump 19 is provided with an inlet pipe, and the end of the inlet pipe is located below the filter screen 16. The output end of the water pump 19 is provided with an outlet pipe, which is sealed and connected to the water supply pipe 4. The inlet pipe at the input end of the water pump 19 can extend into the lower side of the filter screen 16, which can prevent the water drawn from the filter box 14 from containing waste residue. The output pipe at the output end of the water pump 19 is connected to the water tank 3, so that the high-pressure nozzle 6 can work stably and continuously. A water inlet is also provided on the outside of the water tank 3, which can improve the stability of the high-pressure nozzle 6.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
