Description

Technical Field

[0001] The invention relates to the field of dust removal equipment design, and in particular to energy-saving and noise-reducing dust removal equipment. Background Art

[0002] After the products and spare parts are produced, dust is easily attached during transportation and assembly, so dust removal is required. However, the traditional dust removal method is to use compressed air for dust removal. Rows of air holes and rotating disks are set in the dust removal equipment to connect the blowing joints. Compressed air will be blown out at the blowing joints and rotated through the rotating disk to achieve rotating blowing, or compressed air is directly connected to a single row of multiple air holes to allow compressed air to blow and dust the spare parts transported on the conveyor belt.

[0003] Due to the different structures and sizes of products that need dust removal, product entrances and exits must be left in the process of continuous transmission operations. Compressed air is blown through rows of air holes or rotating disks connected to blowing joints. During the blowing process, frequent and unstable wind whistling sounds will be generated, and when the air volume hits the product, a "sonic boom" will be generated, and the noise can be as high as 100 decibels.

[0004] The above factors will bring long-term noise impact to the working environment of the production line. Operators need to work in this high-noise environment for a long time. Studies have found that when the volume exceeds 80-85 decibels, it is easy to cause permanent hearing loss. Due to the different physical conditions of each person, some people will be hurt at less than 80 decibels. Long-term exposure to a noise environment above 85 decibels may cause obvious damage to hearing. Staying in an environment above 90 decibels for 4 hours will cause obvious damage to hearing.

[0005] In addition, in the existing dust removal scheme, the use of a single-row multi-hole method has the problem of high gas consumption, resulting in serious energy waste and failure to achieve energy-saving effects; another implementation method of the existing equipment is to use a rotating disk to drive the blowing joint to rotate, which generally uses air pressure to control the rotation of the rotating disk. Affected by the air pressure, the rotation speed will be unstable and the surface of the product cannot be evenly blown, resulting in poor dust removal effect; in addition, in the existing rotary dust removal method, the nozzle can only move within the circular range of the disk, and the dust at the edge of the product may not be blown away, affecting the dust removal effect. Summary of the invention

[0006] In order to overcome the above-mentioned shortcomings, the present invention provides a technical solution that can solve the above-mentioned problems.

[0007] An energy-saving and noise-reducing dust removal device comprises a frame on which a dust removal module is installed; The dust removal module includes a sound absorption and noise reduction module and an air blowing module, and one side of the sound absorption and noise reduction module is semi-enclosed and covered on the air blowing module; The blowing module comprises a housing and a rotating shaft, a ventilation groove is formed on the top side of the housing, one or more rotating shafts are provided, the rotating shaft is rotatably mounted on the bottom side of the ventilation groove, the bottom end of the rotating shaft is passed into the housing, a blowing rod is fixedly installed on the bottom end of the rotating shaft, and the blowing rods of two adjacent rotating shafts are staggered with each other; Both sides of the bottom side of the blowing module and the sound absorption and noise reduction module form a vacuum air flow channel, an exhaust pipe is installed in the sound absorption and noise reduction module, and the air flow channel and the exhaust pipe are interconnected.

[0008] Furthermore: a mainstream air hole is formed in the rotating shaft, a diversion air hole is formed in the blowing rod, the mainstream air hole and the diversion air hole are interconnected, the upper end of the mainstream air hole leads to the ventilation groove, and the diversion air hole leads to the casing.

[0009] Further: a semi-enclosed groove is formed on one side of the sound absorption and noise reduction module, a dust suction port is formed in the semi-enclosed groove, and the dust suction port is connected between the air flow channel and the exhaust duct.

[0010] Further: the casing of the blowing module is installed in the semi-enclosed groove by pulling.

[0011] Furthermore: sound absorbing panels are fixedly installed on both sides of the casing, sound absorbing and noise reduction materials are filled and installed between the sound absorbing panels and the casing, and sound absorbing and noise reduction materials are also filled and installed in the sound absorbing and noise reduction module.

[0012] Further: a conveyor line is installed on the frame, and the conveyor line drives the product through the blowing module.

[0013] Furthermore: there are two dust removal modules, and the two dust removal modules are symmetrically arranged with respect to each other.

[0014] Furthermore: there are two conveying lines, and the conveying lines are installed one by one in the dust removal modules on the upper and lower sides.

[0015] Further: the conveyor line includes an active roller, multiple driven rollers and multiple third transmission belts. The active roller and the driven rollers are rotatably installed in the dust removal module, and the third transmission belt is installed between an active roller and multiple driven rollers.

[0016] Furthermore: a driving sprocket is fixedly installed at one end of the active roller, a sprocket tensioning mechanism is fixedly installed on the lower dust removal module, a driven sprocket is rotatably installed on the sprocket tensioning mechanism, and a transmission chain is installed between the two driving sprockets and the driven sprocket.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Using the sound-absorbing and noise-reducing module to semi-enclose the dust removal module can block the noise generated by the dust removal module when it is working to a certain extent. The sound-absorbing and noise-reducing module has sound-absorbing and noise-reducing materials, which can achieve sound absorption and noise reduction, and can effectively reduce the noise of the dust removal equipment when it is working to below 80 decibels; 2. Directly introduce high-pressure gas into the ventilation groove. The high-pressure gas will blow inside the casing through the rotating shaft and the blowing rod. The rotating shaft can rotate, thereby driving the blowing rod to blow inside the casing. Through the laminar flow formed by the dust removal area, the technical effect of effectively raising the dust on the product surface can be achieved; 3. The blowing rods between two adjacent rotating shafts are interlaced, so the blowing rods are not blocked during operation, achieving 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, have a higher air pressure in the same dust removal space, thereby improving its dust removal effect; 4. The air blowing module can be pulled out by pulling, which makes it convenient to clean the dust in the air flow channel; 5. The lifting unit can be used to drive one of the dust removal modules to move up and down, so that the blowing rod and the air flow channel are closer to the product, achieving better dust raising and dust suction effects. At the same time, the sound absorption and noise reduction module can also be closer to the product, thereby achieving better noise reduction effects. 6. You can use a single-sided dust removal module to remove dust from one surface of the product, or you can use two symmetrical dust removal modules on both sides to remove dust from the upper and lower surfaces of the product at the same time. It has a wide range of applications.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figure 1-18 As shown, an energy-saving and noise-reducing dust removal device of the present invention comprises a frame 1, on which a dust removal module 2 is installed; The dust removal module 2 includes a sound absorption and noise reduction module 2.1 and an air blowing module 2.2. One side of the sound absorption and noise reduction module 2.1 is semi-enclosed and covered on the air blowing module 2.2. The sound absorption and noise reduction module 2.1 semi-encloses and covers the air blowing module 2.2, which can block the noise generated by the dust removal module when it is working to a certain extent. The sound absorption and noise reduction module 2.1 has a sound absorption and noise reduction material 18 to achieve sound absorption and noise reduction, and can effectively reduce the noise of the dust removal equipment when it is working to less than 80 decibels. The 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. The rotating shaft 2.22 is provided with one or more. The rotating shaft 2.22 is rotatably mounted on the bottom side of the ventilation groove 3. The bottom end of the rotating shaft 2.22 is connected to the housing 2.21. A blowing rod 4 is fixedly mounted on the bottom end of the rotating shaft 2.22. The blowing rods 4 of two adjacent rotating shafts 2.22 are staggered with each other. By utilizing the staggered blowing rods 4, the two adjacent rotating shafts 2.22 do not interfere with each other during the rotational movement. The blowing rods 4 are not blocked during operation. High-pressure gas is blown onto the surface of the product through the 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. Moreover, the staggered blowing rods 4 can also save space for the equipment. A vacuum air flow channel 5 is formed between the two sides of the bottom side of the blowing module 2.2 and the sound absorption and noise reduction module 2.1. An exhaust duct 6 is installed in the sound absorption and noise reduction module 2.1, and the air flow channel 5 and the exhaust duct 6 are interconnected. When vacuuming, the dust removal module 2 is used to blow high-pressure gas onto the product, thereby raising the dust on the surface of the product, and then vacuuming the air flow channel 5 for dust recovery, thereby effectively removing the dust on the surface of the product. The dust removal effect is better, and the dust removal is not limited to a circular range, and has a larger coverage area.

[0028] Furthermore: a mainstream air hole 7 is formed in the rotating shaft 2.22, and a diversion air hole 8 is formed in the blowing rod 4. The mainstream air hole 7 and the diversion air hole 8 are interconnected, the upper end of the mainstream air hole 7 is connected to the ventilation groove 3, and the diversion air hole 8 is connected to the casing 2.21; by utilizing the connection between the mainstream air hole 7 and the diversion air hole 8, the high-pressure air leading to the ventilation groove 3 can enter the casing 2.21 along the mainstream air hole 7 and the diversion air hole 8 for blowing, thereby achieving the effect of effective blowing and dust removal, and finally the air containing dust is discharged by vacuuming the air flow channel 5.

[0029] Furthermore: the end of the diverter air hole 8 is connected with an air nozzle; the air nozzle can play a role of pressurization, so that the air pressure of the diverter air hole 8 is higher, achieving a better dust removal effect, and finally the air flow channel 5 is used for dust collection.

[0030] Furthermore: the upper end of the rotating shaft 2.22 and the top side of the ventilation groove 3 are arranged to be separated from each other; so that high-pressure gas can directly enter the upper end of the rotating shaft 2.22, and then enter the mainstream air hole 7 and the branch air hole 8 for blowing. When the rotating shaft 2.22 rotates, it can also stably supply air, and the service life is improved.

[0031] 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 in the semi-enclosed groove 9, and the dust suction port 10 is connected between the air flow channel 5 and the exhaust duct 6; the exhaust duct 6 can be connected to the air flow channel 5 through the dust suction port 10, and then absorb the air containing dust to achieve an effective dust suction effect.

[0032] 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 air flow channel 5; after the dust on the product is lifted up, it can be discharged through the air flow channel 5, thereby achieving the effect of effective dust removal and dust suction.

[0033] Furthermore: the outer end of the exhaust duct 6 is connected to a centrifugal fan; the centrifugal fan can be used to enhance the adsorption force of the airflow channel 5 to achieve the technical effect of effective dust collection.

[0034] Furthermore: the housing 2.21 of the blowing module 2.2 is installed between the two positioning edges 11 by pulling; when used for a long time, dust will accumulate in the air flow channel 5, and the blowing module 2.2 can be pulled out by side pulling, which makes it convenient to clean the dust in the air flow channel 5.

[0035] Furthermore: the distance between the bottom edge of the positioning edge 11 and the inner wall of the semi-enclosed groove 9 is smaller than the distance between the top edge of the positioning edge 11 and the inner wall of the semi-enclosed groove 9; the distance between the airflow channel 5 is set to be wider at the top and narrower at the bottom, which can form a unique guide structure. A pressure difference will be generated in the unique guide structure to form a vacuum wind chamber, which is used to accelerate the flow speed of the gas and thus ensure its dust removal effect.

[0036] Furthermore: a first motor 12 is fixedly mounted on the casing 2.21, and the first motor 12 drives one or more rotating shafts 2.22 to operate synchronously; a first motor 12 can be used to drive multiple rotating shafts 2.22 to operate synchronously, and when the rotating shafts 2.22 rotate synchronously, the blowing rods 4 thereon can not interfere with each other. In addition, the motor-driven method has higher stability, the rotation speed is not affected by air pressure, and there is no need to use multiple motors, which has a better energy-saving effect.

[0037] Furthermore: a driving pulley 13 is fixedly installed at the rotor of the first motor 12, 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 driving 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 driving is achieved by utilizing the cooperation of the belts, thereby achieving stable operation between multiple rotating shafts 2.22.

[0038] Furthermore, both the front and rear sides of the semi-enclosed groove 9 extend out of the box body; the blowing module 2.2 can be pulled out from the front and rear sides of the semi-enclosed groove 9, thereby facilitating the cleaning of dust in the air flow channel 5.

[0039] Furthermore: sound-absorbing panels 17 are fixedly installed on both sides of the casing 2.21, and sound-absorbing and noise-reducing materials 18 are filled and installed between the sound-absorbing panels 17 and the casing 2.21; when working, compressed air is ejected from the rotating blowing rod 4 of the dust removal module 2, and a whistling sound will be generated at this time. Sound-absorbing and noise-reducing materials 18 are filled between the sound-absorbing panels 17 and the casing 2.21, which can absorb part of the sound, and the air volume blown out from the air nozzle of the blowing rod 4 will hit the product to form a "sonic boom", and these airflows will pass through the airflow channel 5 between the positioning edge 11 and the semi-enclosed groove 9 into the dust suction port 10, and be output through the exhaust duct 6. At this time, the noise can be effectively reduced through the semi-enclosed sound-absorbing and noise-reducing module 2.1, and the transmission of sound can be blocked by multiple media, thereby achieving an effective sound absorption and noise reduction effect.

[0040] Furthermore: the sound-absorbing and noise reduction module 2.1 is also filled with sound-absorbing and noise reduction material 18; the sound-absorbing and noise reduction module 2.1 can be layered, and each layer of the sound-absorbing and noise reduction module 2.1 can be filled with sound-absorbing and noise reduction material 18 to achieve multiple sound-absorbing and noise reduction effects, ensuring that the volume of the equipment can be controlled below 80 decibels during operation.

[0041] The sound-absorbing and noise-reducing material 18 can be made of porous materials, such as foam materials (polyurethane foam, polyester foam, polyethylene foam, etc.). These materials are filled with tiny pores, which can effectively absorb sound wave energy and reduce noise. 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; The sound-absorbing and noise-reducing material 18 can be made of composite materials: such as sound-absorbing foam composite boards, sound-absorbing fiber composite boards, etc., which combine the advantages of different materials and have better sound absorption and sound insulation performance; The sound-absorbing and noise-reducing material 18 can be made of nanomaterials: due to their unique microstructure and physical and chemical properties, they have great potential in sound absorption and noise reduction, and can be combined with other sound-absorbing materials to form composite materials with excellent performance; The sound-absorbing and noise-reducing material 18 can be made of environmentally friendly materials: made of renewable resources or materials with low environmental impact, such as bio-based foam materials, degradable fiber materials, etc., to reduce the burden on the environment; The sound-absorbing and noise-reducing material 18 may be a sound-absorbing film: it has the function of absorbing and degrading low-frequency noise, and effectively reduces noise by laminating multiple layers of sound-absorbing films; The sound-absorbing and noise-reducing material 18 may be a biomass sound-absorbing and noise-reducing material 18 ‌ , such as a wood-wool sound-absorbing board 17 , which is made of natural fibers and plant materials and will not bring adverse effects to the surrounding environment.

[0042] Furthermore: the cross-section of the sound-absorbing and noise-reduction module 2.1 is any one of a trapezoidal, semicircular, semi-elliptical, rectangular, square, and rhombus shape; the sound-absorbing 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 by the sound-absorbing and noise-reduction module 2.1, it is within the protection scope of the present invention application.

[0043] Furthermore: a conveyor line 19 is installed on the frame 1; the conveyor line 19 drives the product through the blowing module 2.2, and the blowing module 2.2 can blow high-pressure air evenly to the surface of the product by blowing, thereby effectively raising the dust on the surface of the product, and finally use the air flow channel 5 to suck away the dusty air, thereby achieving the effect of effective dust removal and dust suction.
