Description

Technical Field

[0001] The present invention belongs to the technical field of industrial vacuum cleaners, and in particular relates to a large-suction intelligent industrial vacuum cleaner and a using method thereof. Background Art

[0002] An industrial vacuum cleaner is a device used to collect waste such as dust, debris, and powder during the industrial production process. It usually has a strong suction force and a large dust collection capacity, and can effectively clean the dust and sundries on the ground, equipment surfaces, and in the space of workshops, warehouses, factories, etc. Its main functions are to keep the working environment clean and hygienic, reduce the impact of dust on product quality, prevent safety accidents such as dust explosions, and at the same time help protect the physical health of workers. For example, the patent with the authorization announcement number CN204107252U discloses a powerful industrial vacuum cleaner.

[0003] Currently, the structure of large-suction industrial vacuum cleaners is relatively simple and the degree of intelligence is low, making it impossible for large-suction vacuum cleaners to automatically adjust the suction force according to the particle size of the sucked particulate matter. Therefore, it is necessary for the staff to manually adjust the suction force according to the dust and particulate matter conditions. During the process of manually adjusting the suction force, in order to ensure the dust collection effect, the maximum suction force mode is mostly used for operation, which causes waste of suction force, increases the energy consumption of the industrial vacuum cleaner, and affects the energy conservation and environmental protection performance of the large-suction industrial vacuum cleaner; In addition, during the use of existing large-suction industrial vacuum cleaners, as the amount of dust attached to the filter element increases, the dust collection resistance of the vacuum cleaner also increases accordingly, which will further affect the dust collection effect of the large-suction industrial vacuum cleaner, and frequently requires the staff to pause the vacuum cleaner and then take out the filter element component for dust cleaning. This not only affects the use effect and continuity of the large-suction industrial vacuum cleaner, but also increases the labor intensity of the staff, and affects the convenience of using the large-suction industrial vacuum cleaner.

[0004] Therefore, we propose a large-suction intelligent industrial vacuum cleaner and a using method thereof to solve the above problems. Summary of the Invention

[0011] In the above-mentioned large-suction intelligent industrial vacuum cleaner, the dust suction mechanism includes a bracket fixedly connected to the upper surface of the second support mesh plate.

[0012] In the above-mentioned large-suction intelligent industrial vacuum cleaner, a rectangular through hole is formed in the side wall of the dust suction cover, and an L-shaped sealing plate matched with the cylindrical part at the top end of the dust suction cover is hermetically and movably connected to the hole wall of the rectangular through hole. An electric push rod is fixedly connected to the outer wall of the dust suction cover. The moving end of the electric push rod is fixedly connected to the outer wall of the L-shaped sealing plate.

[0013] A using method of a large-suction intelligent industrial vacuum cleaner includes the following steps: Step S1: First, control the suction fan of the dust suction mechanism to start through the control panel, and suck the outside air through the dust suction mechanism. While the outside air is sucked into the dust suction cover, it carries dust or particles into the fixed cylinder. Then, the outside air passes through the composite filter cartridge and is discharged, while the dust or particles are intercepted by the composite filter cartridge; Step S2: While step S1 is running, the CCD camera takes images of the dust and particles on the ground, converts the images into electrical signals and transmits them to the computer. The computer analyzes the volume of the particulate matter and generates electrical signals of corresponding size levels to the PLC controller. The PLC controller controls the suction force of the suction fan according to the electrical signals sent by the computer. The larger the volume of the particulate matter, the greater the suction force of the suction fan for sucking air. On the contrary, the smaller the volume of the particulate matter, the lower the suction force of the suction fan for sucking air; Step S3: While step S1 is running, the outside air sucked from within the composite filter cartridge drives the multi-blade fan to rotate. The multi-blade fan drives the composite filter cartridge to rotate through the threaded pipe, and the outer wall of the composite filter cartridge circulates past the filter dust cleaning mechanism. Moreover, the airflow ejected by the filter dust cleaning mechanism can backflush from the inside of the composite filter cartridge and continuously clean the dust on the outer wall of the composite filter cartridge; Step S4: When it is necessary to use a high-suction industrial vacuum cleaner to clean the dust on the surface of workshop equipment and in narrow spaces, the staff removes the hard pipe from the connection cover, and at the same time removes the sealing plug at the air inlet end of the hard pipe. Then, the top of the suction hood is blocked by the L-shaped sealing plate to prevent the suction hood from sucking outside air. After that, the staff holds the hard pipe to clean the dust on the surface of workshop equipment or in narrow spaces.

[0014] Compared with the existing technology, the advantages of a high-suction intelligent industrial vacuum cleaner and its usage method are as follows: 1. Through the CCD camera, control mechanism, and suction mechanism set, when the factory needs to clean the dust or particulate matter on the ground with an industrial vacuum cleaner, the staff first controls the suction mechanism to start through the control panel. The suction mechanism sucks outside air through the suction hood. The sucked outside air will carry dust or particulate matter into the fixed cylinder. The dust and particulate matter are intercepted by the composite filter cartridge, and the clean air is discharged by the vacuum cleaner. At the same time, the CCD camera cooperates with the computer to analyze the volume of the particulate matter about to be sucked into the vacuum cleaner and adjust the suction of the suction fan according to the size of the particulate matter volume. If the volume of the sucked particulate matter is small, the suction of the suction fan is reduced to reduce the energy consumption of the vacuum cleaner and avoid the situation of high energy consumption when the vacuum cleaner operates in a high-power mode for small particulate matter volume. This mechanism enables the high-suction industrial vacuum cleaner to automatically adjust the suction according to the size of the sucked particulate matter, while meeting the high-suction cleaning effect, reducing the energy consumption of the high-suction industrial vacuum cleaner, and thus improving the energy conservation and environmental protection performance of the high-suction industrial vacuum cleaner.

[0015] 2. During the dust suction and cleaning process, with the air flow dust filtering mechanism and filter element dust cleaning mechanism provided, when the air flow enters the exhaust hood through the composite filter element cylinder, the air flow acts on the multi-blade fan. The multi-blade fan drives the composite filter element cylinder to rotate through the threaded pipe. After the composite filter element cylinder rotates, each dust filtering part of the composite filter element cylinder passes through the filter element dust cleaning mechanism. At the same time, the outside air sucked by the suction fan is compressed by the air guide hood and then split into two streams when passing through the three-way pipe. One of the air streams enters the arc-shaped hood through the branch pipe and is then sprayed onto the inner side wall of the composite filter element cylinder at the collection hood through the threaded pipe and the filter element dust cleaning mechanism, using the air flow ejected from the inside of the composite filter element cylinder to backflush and clean the dust. Since each dust filtering position on the outer wall of the composite filter element cylinder will pass through the collection hood, it is possible to achieve comprehensive dust cleaning of the outer wall of the composite filter element cylinder, ensuring that dust will not block the dust filtering channel during the dust filtering of the composite filter element cylinder and increasing the dust filtering resistance, ensuring that the vacuum cleaner continuously maintains a large suction force dust suction effect. At the same time, there is no need for the staff to frequently pause the vacuum cleaner to clean the composite filter element cylinder, saving time and effort. This mechanism enables the large suction industrial vacuum cleaner to have the function of automatic dust cleaning of the filter element, not only ensuring that the composite filter element cylinder has the ability to continuously and efficiently filter dust, but also ensuring that the vacuum cleaner has a continuous large suction force dust suction effect, improving the use effect and continuity of the large suction industrial vacuum cleaner, and reducing the labor intensity of the staff.

[0016] 3. With the L-shaped sealing plate, electric push rod and hard pipe provided, when the large suction industrial vacuum cleaner is needed to clean the dust on the surface of workshop equipment and in narrow spaces, the staff takes out the hard pipe from the connecting hood, removes the sealing plug at the air inlet end of the hard pipe, and then controls the L-shaped sealing plate to block the suction hood through the electric push rod, so that the suction hood cannot suck the outside air. At the same time, the corrugated pipe sucks the outside air through the second air pipe and the hard pipe. Then the staff holds the hard pipe and performs the dust cleaning operation on the surface of workshop equipment or in narrow spaces. This mechanism enables the large suction industrial vacuum cleaner to have the function of adapting to different position dust suction requirements, improving the use reliability of the vacuum cleaner.

[0025] The suction fan 72, the supplementary light 14, and the electric push rod 18 are all electrically connected to the output end of the PLC controller 52 through wires. The CCD camera 13 is electrically connected to the input end of the computer 51 through a data cable. Both the computer 51 and the control panel 54 are electrically connected to the input end of the PLC controller 52 through data cables. The above-mentioned powered devices and electrical connections are all prior arts and will not be elaborated here.

[0026] Now, the operation principle of the present invention is described as follows: When the factory needs to clean the ground dust or particulate matter through the industrial vacuum cleaner, the staff first controls and starts the suction fan 72 through the control panel 54. The suction fan 72 sucks the air inside the composite filter cartridge 611 through the first air pipe 73 and the exhaust hood 66, making the inside of the composite filter cartridge 611 form a low-pressure environment. To balance the pressure, the composite filter cartridge 611 in the low-pressure state sucks the outside air through the fixed cylinder 61, the collection cylinder 62, the corrugated pipe 79, and the dust suction cover 78. During the process of sucking the outside air, the ground dust or particulate matter is sucked in with the outside air to achieve the cleaning purpose. When the outside air passes through the composite filter cartridge 611, the dust or particulate matter carried by the outside air is intercepted by the composite filter cartridge 611 and falls into the collection cylinder 62 for temporary storage. Finally, the clean outside air is discharged through the air guiding cover 74 and the three-way pipe 75. During the cleaning operation of the industrial vacuum cleaner, the fill light 14 is powered on to provide sufficient illumination for the CCD camera 13, ensuring that the CCD camera 13 can clearly capture images of dust and particulate matter that have not been sucked in by the vacuum cleaner. After that, the CCD camera 13 captures images of dust and particulate matter on the ground and converts the images into electrical signals, which are transmitted to the computer 51. The computer 51 is pre-installed with an image analysis and comparison program. Multiple level thresholds related to the size of particulate matter are set in this program. Through the analysis and comparison program pre-installed in the computer 51, the geometric features such as the pixel area and perimeter of particulate matter in the images captured by the CCD camera 13 are analyzed. Combining the pre-calibrated conversion relationship between pixels and actual sizes, the actual size of particulate matter is calculated, and then the level of particulate matter size is determined. Then, the computer 51 sends an electrical signal corresponding to the analyzed level to the PLC controller 52. According to the received electrical signal and the preset control strategy, the PLC controller 52 generates corresponding control instructions, and these instructions are transmitted to the motor frequency converter in the suction fan 72 in the form of standard signals. When it is necessary to increase the suction force of the suction fan 72, the signal sent by the PLC controller 52 will cause the frequency converter to increase the output frequency of alternating current, and the motor speed of the suction fan 72 will increase accordingly, and the suction force of the suction fan 72 will increase. On the contrary, when it is necessary to reduce the suction force, the output frequency of the motor frequency converter in the suction fan 72 decreases, the motor speed of the suction fan 72 decreases, and the suction force of the suction fan 72 decreases. Through this regulation process, the suction fan 72 can respond to the suction force requirements of different particulate matter sizes in real time and accurately. Moreover, the larger the volume of particulate matter, the higher the suction force controlled by the PLC controller 52 for the suction fan 72, and the two are in a proportional relationship. If the volume of the sucked particulate matter is small, the suction force of the suction fan 72 is reduced to reduce the energy consumption of the vacuum cleaner, avoiding the situation of high energy consumption when the vacuum cleaner operates in a high-power mode due to small particulate matter volume. This mechanism enables the large-suction industrial vacuum cleaner to have the function of automatically adjusting the suction force according to the size of the sucked particulate matter, reducing the energy consumption of the large-suction industrial vacuum cleaner while meeting the cleaning effect of large suction, and thus improving the energy-saving and environmental protection performance of the large-suction industrial vacuum cleaner; During the vacuum cleaning process, when the air flow enters the exhaust hood 66 through the composite filter cartridge 611, the air flow acts on the multi-blade fan 81. The multi-blade fan 81 rotates under the influence of the air flow and simultaneously drives the threaded tube 69 to rotate within the first sealing bearing 68. Then, the rotating threaded tube 69 drives the composite filter cartridge 611 to rotate through the chassis 610. When the composite filter cartridge 611 rotates, the outer wall of the top end of the composite filter cartridge 611 can be kept in a sealed and isolated state through the limit bearing 612 and the sealing rubber ring 613. After the composite filter cartridge 611 rotates, each dust filtering part of the composite filter cartridge 611 passes through the filter element dust cleaning mechanism 8. At the same time, the outside air sucked by the suction fan 72 is compressed by the air guide hood 74 and then split into two streams when passing through the three-way pipe 75. One stream of air is discharged through the outlet end of the three-way pipe 75 and the third support mesh plate 77, and the other stream of air enters the arc-shaped hood 67 through the branch pipe 76, then enters the strip-shaped nozzle 86 through the threaded tube 69, the air outlet hole 84, the connecting sleeve 83 and the horizontal pipe 85, and finally is sprayed by the strip-shaped nozzle 86 onto the inner side wall of the composite filter cartridge 611 at the collection hood 87. The dust attached to the outer wall of the composite filter cartridge 611 is cleaned by the air flow ejected from the inside of the composite filter cartridge 611. The cleaned dust is discharged into the collection cylinder 62 through the collection hood 87 and the dust discharge pipe 89. Since each dust filtering position on the outer wall of the composite filter cartridge 611 will pass through the collection hood 87, the outer wall of the composite filter cartridge 611 can be comprehensively cleaned of dust, ensuring that the dust will not block the dust filtering channel during the dust filtering of the composite filter cartridge 611 and increasing the dust filtering resistance. This ensures that the vacuum cleaner continuously maintains a large suction force for the vacuuming effect. At the same time, it is not necessary for the staff to frequently pause the vacuum cleaner, and it is not necessary to manually remove the composite filter cartridge 611 for dust cleaning work, saving time and effort. This mechanism enables the large suction industrial vacuum cleaner to have the function of automatic dust cleaning of the filter element, not only ensuring that the composite filter cartridge 611 has the ability to continuously and efficiently filter dust, but also ensuring that the vacuum cleaner has a continuous large suction force for the vacuuming effect, improving the use effect and continuity of the large suction industrial vacuum cleaner, reducing the labor intensity of the staff, and improving the convenience of using the large suction industrial vacuum cleaner; When it is necessary to use a high-suction industrial vacuum cleaner to clean the dust on the surface of workshop equipment and in narrow spaces, the staff first rotate the threaded ring 712, remove the hard pipe 711 from the connecting cover 4, and at the same time remove the sealing plug 713 at the air inlet end of the hard pipe 711. Then, the staff control the retraction of the moving end of the electric push rod 18 through the control panel 54. The moving end of the electric push rod 18 drives the L-shaped sealing plate 9 to move into the dust suction cover 78 and block the top of the dust suction cover 78, so that the dust suction cover 78 cannot suck in external air. At the same time, the bellows 79 sucks in external air through the second air pipe 710 and the hard pipe 711. After that, the staff hold the hard pipe 711 and perform dust cleaning operations on the surface of workshop equipment or in narrow spaces. After the dust is transported to the fixed cylinder 61 and intercepted by the composite filter cartridge 611, it will fall into the collection cylinder 62. This mechanism enables the high-suction industrial vacuum cleaner to specifically adapt to the dust suction requirements at different positions, improving the reliability of the vacuum cleaner.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
