Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment design, and in particular to an energy-saving and noise-reducing dust removal equipment. Background Technology

[0002] After products and spare parts are manufactured, they are prone to dust accumulation during transportation and assembly, thus requiring dust removal. However, the traditional dust removal method uses compressed air. The dust removal equipment is equipped with rows of air holes and a rotating disc connected to the air blowing connector. Compressed air is blown out at the air blowing connector and rotated through the rotating disc to blow air. Alternatively, compressed air can be directly connected to a single row of multiple air holes to blow air onto the spare parts conveyed on the conveyor belt to remove dust.

[0003] Because the products requiring dust removal have different structures and sizes, product inlets and outlets must be left during continuous transmission operations. Compressed air is blown through rows of air holes or a rotating disc connected to an air blowing connector. During this blowing process, frequent and unstable whistling sounds will be generated, and when the air volume hits the product, it will also produce a "sonic boom", with noise levels reaching up to 100 decibels.

[0004] The above factors will have a long-term noise impact on the production line's working environment, requiring workers to work in this high-noise environment for extended periods. Studies have found that when the volume exceeds 80-85 decibels, it can easily cause permanent hearing loss. Due to individual differences, some people may experience damage even at levels below 80 decibels. Long-term exposure to noise levels above 85 decibels may cause significant hearing damage, and spending 4 hours in an environment above 90 decibels will also cause significant hearing damage.

[0005] Furthermore, existing dust removal solutions using a single-row multi-hole method suffer from high air consumption, leading to significant energy waste and failing to achieve energy-saving effects. Another implementation method in existing equipment uses a rotating disc to drive the air blowing connector to rotate, which is generally controlled by air pressure. This is affected by the air pressure, resulting in unstable rotation speed and an inability to evenly blow dust onto the product surface, leading to poor dust removal efficiency. In addition, in existing rotary dust removal methods, the nozzles can only move within the circular range of the disc, and dust located at the edges of the product may not be blown away, affecting the dust removal effect. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0007] An energy-saving and noise-reducing dust removal device includes a frame on which a dust removal module is installed;

[0008] The dust removal module includes a sound absorption and noise reduction module and an air blowing module, with one side of the sound absorption and noise reduction module partially enclosing and covering the air blowing module.

[0009] The air blowing module includes a housing and a rotating shaft. The top side of the housing is formed with an air vent. One or more rotating shafts are provided. The rotating shafts are rotatably installed on the bottom side of the air vent. The bottom end of the rotating shaft is inserted into the housing. An air blowing rod is fixedly installed at the bottom end of the rotating shaft. The air blowing rods of two adjacent rotating shafts are arranged alternately.

[0010] The two sides of the bottom of the air blowing module and the sound absorption and noise reduction module form a vacuum airflow channel. The sound absorption and noise reduction module is equipped with an exhaust pipe, and the airflow channel and the exhaust pipe are interconnected.

[0011] Furthermore: the rotating shaft has a main air hole formed inside, and the blowing rod has a branch air hole formed inside. The main air hole and the branch air hole are interconnected. The upper end of the main air hole is connected to a ventilation groove, and the branch air hole is connected to the housing.

[0012] Furthermore, a semi-enclosed groove is formed on one side of the sound absorption and noise reduction module, and a dust suction port is formed inside the semi-enclosed groove, which is connected between the airflow channel and the exhaust pipe.

[0013] Furthermore, the housing of the air blowing module is installed in a semi-enclosed groove by a pull-out method.

[0014] Furthermore: sound-absorbing panels are fixedly installed on both sides inside the housing, and sound-absorbing and noise-reducing materials are filled between the sound-absorbing panels and the housing. Sound-absorbing and noise-reducing modules are also filled with sound-absorbing and noise-reducing materials.

[0015] Furthermore: a conveyor line is installed on the frame, and the conveyor line drives the product through the air blowing module.

[0016] Furthermore, there are two dust removal modules, and the two dust removal modules are arranged symmetrically to each other.

[0017] Furthermore, there are two conveyor lines, and each conveyor line is installed in a corresponding manner in the dust removal modules on the upper and lower sides.

[0018] Furthermore: the conveyor line includes a driving roller, multiple driven rollers and multiple third drive belts. The driving roller and the driven rollers are rotatably mounted in the dust removal module, and the third drive belts are mounted between the driving roller and the multiple driven rollers.

[0019] Furthermore: a drive sprocket is fixedly installed at one end of the drive roller, a sprocket tensioning mechanism is fixedly installed on the dust removal module below, a driven sprocket is rotatably installed on the sprocket tensioning mechanism, and a transmission chain is installed between the two drive sprockets and the driven sprocket.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. Using a sound-absorbing and noise-reducing module to partially surround the dust removal module can block the noise generated by the dust removal module during operation to a certain extent. The sound-absorbing and noise-reducing module contains sound-absorbing and noise-reducing materials, which can effectively reduce the noise of the dust removal equipment during operation to below 80 decibels.

[0022] 2. High-pressure gas is directly introduced into the ventilation slot. The high-pressure gas will blow through the rotating shaft and the blowing rod inside the machine casing. The rotating shaft can rotate, thereby driving the blowing rod to sweep inside the machine casing. Through the laminar flow formed in the dust removal area, the technical effect of effectively raising the dust on the product surface is achieved.

[0023] 3. The air blowing rods between two adjacent rotating shafts are intertwined, so the air blowing rods are not obstructed when they are running, achieving a stable blowing action. Multiple rotating shafts can be driven by a single motor, which has a more energy-saving effect and can also effectively save equipment space, or in other words, it has a greater air pressure in the same dust removal space, thereby improving its dust removal effect.

[0024] 4. The air blowing module can be pulled out by a pull-out method, which makes it easier to clean the dust in the airflow channel;

[0025] 5. A lifting unit can be used to move one of the dust removal modules up and down, thereby bringing the air blower and airflow channel closer to the product to achieve better dust dispersal and suction effects. At the same time, the sound absorption and noise reduction module can also be brought closer to the product to achieve better noise reduction effects.

[0026] 6. A single dust removal module can be used to remove dust from one surface of the product, or two symmetrical dust removal modules on both sides can be used to remove dust from the upper and lower surfaces of the product simultaneously, making it widely applicable.

[0027] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0048] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0049] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] like Figure 1-18 As shown, the present invention provides an energy-saving and noise-reducing dust removal device, which includes a frame 1 on which a dust removal module 2 is installed;

[0054] The dust removal module 2 includes a sound absorption and noise reduction module 2.1 and an air blowing module 2.2. The sound absorption and noise reduction module 2.1 is semi-enclosed and installed on one side of the air blowing module 2.2. By using the sound absorption and noise reduction module 2.1 to semi-enclose and cover the air blowing module 2.2, the noise generated by the dust removal module can be blocked to a certain extent. The sound absorption and noise reduction module 2.1 contains sound absorption and noise reduction material 18 to achieve sound absorption and noise reduction, which can effectively reduce the noise of the dust removal equipment to below 80 decibels.

[0055] The air blowing module 2.2 includes a housing 2.21 and a rotating shaft 2.22. A ventilation groove 3 is formed on the top side of the housing 2.21. One or more rotating shafts 2.22 are provided, and the rotating shafts 2.22 are rotatably mounted on the bottom side within the ventilation groove 3. The bottom end of the rotating shaft 2.22 extends into the housing 2.21, and an air blowing rod 4 is fixedly installed at the bottom end of the rotating shaft 2.22. The air blowing rods 4 of adjacent rotating shafts 2.22 are arranged alternately. The staggered arrangement of the air blowing rods 4 ensures that adjacent rotating shafts 2.22 do not interfere with each other during rotation. The air blowing rods 4 operate unobstructed, and high-pressure gas is blown onto the surface of the product through the air blowing rods 4, thereby raising dust and achieving effective dust removal. One motor can be used to drive multiple rotating shafts 2.22 to operate synchronously, which is more energy-efficient. Furthermore, the staggered arrangement of the air blowing rods 4 saves space in the equipment.

[0056] The air blowing module 2.2 and the sound absorption and noise reduction module 2.1 together form a vacuum airflow channel 5. The sound absorption and noise reduction module 2.1 is equipped with an exhaust pipe 6. The airflow channel 5 and the exhaust pipe 6 are interconnected. When vacuuming, the dust removal module 2 blows high-pressure gas onto the product, thereby stirring up the dust on the product surface. Then, the dust is collected by vacuuming through the airflow channel 5, thus effectively removing the dust from the product surface. The dust removal effect is better and it is not limited to dust removal within a circular area, but has a larger coverage area.

[0057] Furthermore: the rotating shaft 2.22 has a main air hole 7 formed inside, and the blowing rod 4 has a diversion air hole 8 formed inside. The main air hole 7 and the diversion air hole 8 are interconnected. The upper end of the main air hole 7 is connected to the ventilation groove 3, and the diversion air hole 8 is connected to the housing 2.21. By utilizing the connection between the main air hole 7 and the diversion air hole 8, the high-pressure air that leads to the ventilation groove 3 can enter the housing 2.21 through the main air hole 7 and the diversion air hole 8 for blowing, thereby achieving the effect of effectively blowing away dust. Finally, the air containing dust is discharged by vacuuming through the airflow channel 5.

[0058] Furthermore, an air nozzle is connected to the end of the diversion air hole 8; the air nozzle can pressurize the air, making the air pressure of the diversion air hole 8 higher, achieving a better dust-suppressing effect, and finally the airflow channel 5 is used to perform the dust-suppressing action.

[0059] Furthermore, the upper end of the rotating shaft 2.22 and the top side of the ventilation groove 3 are separated from each other; this allows high-pressure gas to be directly introduced into the upper end of the rotating shaft 2.22, and then into the main air hole 7 and the branch air hole 8 for blowing. The rotating shaft 2.22 can also supply gas stably when it rotates, thus improving its service life.

[0060] Furthermore, a semi-enclosed groove 9 is formed on one side of the sound absorption and noise reduction module 2.1, and a dust suction port 10 is formed inside the semi-enclosed groove 9. The dust suction port 10 is connected between the airflow channel 5 and the exhaust pipe 6. The exhaust pipe 6 can be connected to the airflow channel 5 through the dust suction port 10, thereby sucking in air containing dust and achieving an effective dust suction effect.

[0061] Furthermore, positioning edges 11 are fixedly installed on both sides of the semi-enclosed groove 9. The inner wall of the semi-enclosed groove 9 and the positioning edges 11 are separated from each other and form a vacuum airflow channel 5. After the dust on the product is raised, it can be discharged through the airflow channel 5, thereby achieving the effect of effective dust removal and dust collection.

[0062] Furthermore, a centrifugal fan is connected to the outer end of the exhaust pipe 6; the centrifugal fan can be used to enhance the adsorption force of the airflow channel 5, thereby achieving the technical effect of effective dust collection.

[0063] Furthermore: the housing 2.21 of the air blowing module 2.2 is installed between the two positioning edges 11 by a pull-out method; during long-term use, dust will accumulate in the airflow channel 5, and the air blowing module 2.2 can be pulled out by a side pull-out method, which makes it easier to clean the dust in the airflow channel 5.

[0064] Furthermore: the distance between the bottom edge of the positioning edge 11 and the inner wall of the semi-enclosed groove 9 is less than the distance between the top edge of the positioning edge 11 and the inner wall of the semi-enclosed groove 9; the spacing of the airflow channel 5 is set to be wider at the top and narrower at the bottom, which can form a unique flow guiding structure. The unique flow guiding structure will generate a pressure difference and thus form a vacuum air cavity, which is used to accelerate the flow speed of the gas and thus ensure its dust removal effect.

[0065] Furthermore, a first motor 12 is fixedly installed on the housing 2.21. The first motor 12 drives one or more rotating shafts 2.22 to operate synchronously. One first motor 12 can be used to drive multiple rotating shafts 2.22 to operate synchronously. When the rotating shafts 2.22 rotate synchronously, the air blowing rods 4 on them can not interfere with each other. In addition, the motor-driven method has higher stability, the speed is not affected by air pressure, and there is no need to use multiple motors, resulting in better energy saving.

[0066] Furthermore: a drive pulley 13 is fixedly installed on the rotor of the first motor 12, and a driven pulley 14 is fixedly installed on the outer side of the upper end of the rotating shaft 2.22. A first transmission belt 15 is installed between the drive pulley 13 and the driven pulley 14, and a second transmission belt 16 is installed between the driven pulleys 14 of two adjacent rotating shafts 2.22. Stable drive is achieved by using the belt connection method, and stable operation of multiple rotating shafts 2.22 is realized.

[0067] Furthermore, the semi-enclosed groove 9 has its front and rear sides extending out of the housing; the air blowing module 2.2 can be pulled out from the front and rear sides of the semi-enclosed groove 9, which facilitates cleaning the dust in the airflow channel 5.

[0068] Furthermore: Sound-absorbing panels 17 are fixedly installed on both sides inside the housing 2.21, and sound-absorbing and noise-reducing material 18 is filled between the sound-absorbing panels 17 and the housing 2.21; during operation, compressed air is ejected from the air blower 4 in the rotating dust removal module 2, which will generate a whistling sound. The sound-absorbing and noise-reducing material 18 filled between the sound-absorbing panels 17 and the housing 2.21 can absorb some of the sound. The air blown out from the nozzle of the air blower 4 will hit the product to form a "sonic boom". This airflow will enter the dust suction port 10 through the airflow channel 5 between the positioning edge 11 and the semi-enclosed groove 9, and be output through the exhaust pipe 6. At this time, the noise can be effectively reduced by the semi-enclosed sound-absorbing and noise-reducing module 2.1. By blocking the transmission of sound through multiple media, the effective sound absorption and noise reduction effect is achieved.

[0069] Furthermore, the sound absorption and noise reduction module 2.1 is also filled with sound absorption and noise reduction material 18; the sound absorption and noise reduction module 2.1 can be layered, and each layer of the sound absorption and noise reduction module 2.1 can be filled with sound absorption and noise reduction material 18 to achieve multiple sound absorption and noise reduction effects, ensuring that the volume of the device during operation can be controlled below 80 decibels.

[0070] The sound-absorbing and noise-reducing material 18 can be a porous material, such as foam material (polyurethane foam, polyester foam, polyethylene foam, etc.). These materials are filled with tiny pores, which can effectively absorb sound wave energy and reduce noise.

[0071] The sound-absorbing and noise-reducing material 18 can be made of fiber materials, such as glass fiber, rock wool, ceramic fiber, etc., which absorb sound waves through the pore structure between the fibers;

[0072] The sound-absorbing and noise-reducing material 18 can be a composite material, such as sound-absorbing foam composite board, sound-absorbing fiber composite board, etc., which combines the advantages of different materials and has better sound absorption and sound insulation performance;

[0073] The sound-absorbing and noise-reducing material 18 can be made of nanomaterials: due to their unique microstructure and physicochemical properties, they show great potential in sound absorption and noise reduction, and can be combined with other sound-absorbing materials to form high-performance composite materials;

[0074] Sound-absorbing and noise-reducing materials 18 can be made of environmentally friendly materials: such as bio-based foam materials, biodegradable fiber materials, etc., to reduce the burden on the environment;

[0075] The sound-absorbing and noise-reducing material 18 can be a sound-absorbing membrane: it has the function of absorbing and degrading low-frequency noise, and achieves effective noise reduction by stacking multiple layers of sound-absorbing membrane;

[0076] The sound-absorbing and noise-reducing material 18 can be a biomass sound-absorbing and noise-reducing material 18, such as wood fiber sound-absorbing board 17, which is made of natural fibers and plant materials and will not have an adverse impact on the surrounding environment.

[0077] Furthermore: the cross-section of the sound absorption and noise reduction module 2.1 is any shape among trapezoidal, semi-circular, semi-elliptical, rectangular, square, and rhomboid; the sound absorption and noise reduction module 2.1 can be set to any shape, as long as its bottom has a semi-enclosed groove 9 covering the dust removal module, and semi-enclosed noise reduction is performed through the sound absorption and noise reduction module 2.1, it is within the protection scope of this utility model application.

[0078] Furthermore: a conveyor line 19 is installed on the frame 1; the conveyor line 19 drives the product through the air blowing module 2.2, which can blow high-pressure air evenly onto the surface of the product by blowing, thereby effectively raising the dust on the surface of the product, and finally using the airflow channel 5 to suck away the air with dust, thus achieving the effect of effective dust removal and dust suction.

[0079] Furthermore, two dust removal modules 2 are provided, and several guide rail slider mechanisms 20 are fixedly installed between the two dust removal modules 2. The distance between the two dust removal modules 2 is adjusted by raising and lowering the several guide rail slider mechanisms 20, and the two dust removal modules 2 are arranged symmetrically to each other. The arrangement of several guide rail slider mechanisms 20 can ensure stable cooperation between the two dust removal modules 2, so that the gap between the two dust removal modules 2 is always kept in a vertically parallel state, and the product can be effectively dusted when passing through the gap between the two dust removal modules 2.

[0080] Furthermore: A lifting unit 21 is fixedly installed on the frame 1. The lifting unit 21 drives one of the dust removal modules 2 to move up and down. The lifting unit 21 can be used to drive the dust removal module 2 to move up and down, thereby controlling the gap between the two lifting units 21, so that the blowing rod 4 in the dust removal module 2 is closer to the product, and the airflow channel 5 can also be closer to the product, thereby achieving better dust dispersal and dust collection effects. At the same time, the sound absorption and noise reduction module 2.1 can also be closer to the product, and the noise reduction effect is also better.

[0081] Furthermore, the guide rail slider mechanism 20 includes a sliding optical shaft 20.1 and an optical shaft slider 20.2. The upper end of the sliding optical shaft 20.1 is fixedly installed on the upper dust removal module 2, and the sliding optical shaft 20.1 is vertically arranged. The optical shaft slider 20.2 is fixedly installed on the lower dust removal module 2, and the lower end of the sliding optical shaft 20.1 is slidably inserted into the optical shaft slider 20.2. The relative displacement between the two dust removal modules 2 can be achieved by the cooperation of the sliding optical shaft 20.1 and the optical shaft slider 20.2, thereby ensuring the stability when adjusting the conveying gap and enhancing the dust removal effect on the product.

[0082] Furthermore, the lifting unit 21 includes a second motor 21.1, a reducer 21.2, a rotating shaft 21.3, and a pull rope 21.4. The rotating shaft 21.3 is rotatably mounted on the top side of the frame 1. The second motor 21.1 and the reducer 21.2 are both fixedly mounted on the frame 1. The second motor 21.1 drives the rotating shaft 21.3 to rotate through the reducer 21.2. The pull rope 21.4 is wound around the rotating shaft 21.3. A lifting rod 22 is fixedly mounted on the upper dust removal module 2. The outer end of the pull rope 21.4 is fixedly mounted on the lifting rod 22. The second motor 21.1 drives the rotating shaft 21.3 to rotate at a reduced speed through the reducer 21.2. The rotating shaft 21.3 can pull up the upper dust removal module 2 through the pull rope 21.4, thereby allowing the upper dust removal module 2 to perform lifting and lowering actions. This is the same principle as an elevator, which can control the lifting distance of the upper dust removal module 2 with high precision, thereby realizing dust removal processing for different products.

[0083] Furthermore, at least two pull ropes 21.4 are provided to ensure that the dust removal module 2 on the upper side can be raised and lowered stably.

[0084] Furthermore, there are two conveyor lines 19, and each conveyor line 19 is installed in a corresponding manner in the dust removal modules 2 on the upper and lower sides; this allows the product to be stably conveyed to the dust removal modules 2 on the upper and lower sides for dust removal, thereby quickly removing dust from the surface of the product.

[0085] Furthermore, the conveyor line 19 includes a driving roller 19.1, multiple driven rollers 19.2, and multiple third drive belts 19.3. The driving roller 19.1 and the driven rollers 19.2 are rotatably mounted in the dust removal module 2, and the third drive belts 19.3 are mounted between the driving roller 19.1 and the multiple driven rollers 19.2. The product can be stably conveyed on the multiple third drive belts 19.3, which is convenient for actual use and operation.

[0086] Furthermore: One end of the active roller 19.1 is fixedly equipped with an active sprocket 23, and a sprocket tensioning mechanism 24 is fixedly installed on the lower dust removal module 2. A driven sprocket 25 is rotatably mounted on the sprocket tensioning mechanism 24. A transmission chain 26 is installed between the two active sprockets 23 and the driven sprocket 25. Using a single motor, the upper and lower conveyor lines 19 can operate synchronously, resulting in greater energy savings. The transmission chain 26 allows the two active sprockets 23 to rotate synchronously, while their rotation directions are opposite, effectively driving the product to the gap between the two dust removal modules 2 for dust removal.

[0087] Furthermore, the sprocket tensioning mechanism 24 includes a vertical guide rail 24.1 and a sprocket slider 24.2. The vertical guide rail 24.1 is fixedly installed on the lower dust removal module 2, and the sprocket slider 24.2 is slidably installed on the vertical guide rail 24.1. Two driven sprockets 25 are provided, and both driven sprockets 25 are rotatably installed on the sprocket slider 24.2. The transmission chain 26 is installed between the two driving sprockets 23 and the two driven sprockets 25. The principle of the sprocket tensioning mechanism 24 is to use the gravity of the sprocket slider 24.2 and the driven sprockets 25 to achieve tension. Under their own gravity, the sprocket slider 24.2 and the driven sprockets 25 move downward along the vertical guide rail 24.1, at which time the driven sprockets 25 on both sides can drive the transmission chain 26 to be tensioned, thereby achieving stable transmission.

[0088] Furthermore, two telescopic bellows panels 27 are fixedly installed between the two dust removal modules 2. The two telescopic bellows panels 27 are respectively set on the front and rear sides of the dust removal module 2. The telescopic bellows panels 27 on both sides can be used to block dust, so that dust will not fall out of the equipment, ensuring the cleanliness of the area around the equipment, and facilitating subsequent cleaning operations.

[0089] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
