Description

Technical Field

[0002] When feeding powder, a lot of powder will often float in the air due to the impact, and the powder will cause lung disease after being inhaled by the human body. Therefore, when feeding, a dust recovery device is needed to recover the dust generated during feeding, which can not only reduce the serious impact of dust on the health of operators, but also reduce the waste of powder. When the existing dust recovery device for feeding is used, a motor is usually used to drive the blades to rotate, and the suction force generated by the rotation of the blades is used to suck the dust into the dust collection box. However, the motor will generate a lot of heat during a long period of time, and the time First, it will affect the service life of the motor. In order to solve the problem of motor heat dissipation, the existing device installs an additional heat dissipation mechanism to help the motor dissipate heat, which has a high cost. Secondly, when the existing dust recovery device for feeding is in use, in order to prevent the filter in the device from being blocked, a driving force is used to drive the brush to work, and the brush is used to clean the filter to prevent the filter from being blocked.

[0012] Preferably, a controller is fixedly mounted on the outer wall of the box.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When the present invention is used, the blades can be driven to rotate by the drive of the motor, so that the dust in the air can be sucked into the box, and then the dust in the air can be recovered; the filter screen 1 and the filter screen 2 can also be driven to rotate by the drive of the motor, and the impurities attached to the surface can be cleaned by utilizing the rotation of the filter screen 1 and the filter screen 2 themselves, without the need for additional driving force to drive the brush to work, and the filter screen can be cleaned by utilizing the brush, thereby reducing the use cost, and further, there is no need for the operator to disassemble the brush and drop it for cleaning, thereby reducing the workload of the workers.

[0015] 2. When the present invention is used, the motor is used to drive the blades to rotate to generate suction, so that dust in the air can be sucked into the box. In this process, the rotation of the blades will cause the air in the box to be gradually discharged from the exhaust pipe 1. Since the aperture of the exhaust pipe 1 gradually decreases from one end to the other end, the temperature of the air discharged from the exhaust pipe 1 will decrease, and the end of the exhaust pipe with a smaller diameter is aimed at the motor, and the air discharged from the exhaust pipe 1 will blow toward the motor, accelerating the flow of air around the motor. The air discharged from the exhaust pipe 1 is relatively lower than the air around the motor, thereby accelerating the heat dissipation of the motor. There is no need to install an additional heat dissipation mechanism to help the motor dissipate heat, thereby reducing the cost of use; and during the use of the device, after the valve is opened, the air in the box can also be discharged from the exhaust pipe 2. Since the air enters from the large hole and exits from the small hole, the temperature of the air discharged from the exhaust pipe 2 will decrease. At this time, the staff stands at the exhaust port of the exhaust pipe 2, and the discharged air will blow toward the staff, which can slightly cool the staff; therefore, during the use of the present invention, the external discharge of the air in the box can not only help the heat dissipation of the motor during continuous work, but also slightly cool the staff to a certain extent.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 - Figure 6 , the figure shows a dust classification recovery device for feeding of the present invention, including a box body 1, the box body 1 is rotatably connected with a filter tube 2 and a filter tube 3 through a sealed bearing, the trumpet-shaped pipe mouth of the filter tube 2 is fixedly installed with a filter screen 4, and the trumpet-shaped pipe mouth of the filter tube 2 3 is fixedly installed with a filter screen 2 5, the box body 1 is rotatably connected with a rotating shaft 6 through a sealed bearing, two groups of gears 7 are fixedly installed on the outer wall of the rotating shaft 6, the two groups of gears 7 are respectively meshed with a group of gears 8, and the two groups of gears 8 are respectively fixedly installed on the outer walls of the filter tube 2 and the filter tube 2 3, an exhaust pipe 9 is installed through the inner side of the box body 1, the aperture of the exhaust pipe 9 gradually decreases from one end to the other end, and the end with a smaller diameter of the exhaust pipe 9 is aligned with the motor 1001 in the driving component 10;

[0025] The driving assembly 10 includes a motor 1001, which is fixedly mounted on the outer wall of the box body 1. The driving end of the motor 1001 is fixedly connected to a driving rod 1002. The driving rod 1002 is rotatably connected to the box body 1 and a stabilizing seat 1003 through a sealed bearing. The stabilizing seat 1003 is fixedly mounted in the box body 1. A blade 1004 is fixedly mounted on the outer wall of the driving rod 1002. A group of sprockets 1005 are respectively fixedly mounted on the outer wall of the driving rod 1002 and the rotating shaft 6. Both groups of sprockets 1005 are engaged with chains 1006.

[0026] An exhaust pipe 11 is installed through the inner side of the box body 1, and the aperture of the exhaust pipe 11 gradually decreases from one end to the other end. The end of the exhaust pipe 11 with a small aperture is located outside the box body 1, and a valve 12 is installed at the end of the exhaust pipe 11 with a small aperture. When the device is in use, after the valve 12 is opened, the air in the box body 1 can be discharged from the exhaust pipe 11. Since the air enters from the large hole and exits from the small hole, the temperature of the air discharged from the exhaust pipe 11 will decrease. At this time, when the staff stands at the exhaust port of the exhaust pipe 11, the exhausted air will blow towards the staff, which can slightly cool down the staff.

[0027] A collection box 13 and a collection box 2 14 are slidably inserted into the inner side of the box body 1; after the device is used, the collection box 13 and the collection box 2 14 can be slid outward to be pulled out, and then the dust in the collection box 13 and the collection box 2 14 can be recovered.

[0028] The pore size of the filter screen 1 4 is larger than that of the filter screen 2 5; during the use of the device, the air will first contact the filter screen 1 4, and the filter screen 1 4 will filter out the larger dust in the air, and these larger dust will eventually fall into the collection box 1 3; the smaller dust in the air will pass through the pores of the filter screen 1 4, and then the filter screen 2 5 will filter out the remaining smaller dust in the air, and these dust will eventually fall into the collection box 2 14, so that the dust in the air during feeding can be graded and recovered.

[0029] A group of universal wheels 15 with a self-locking structure are installed at the four corners of the bottom of the box body 1, and the outer wall of the box body 1 is fixedly connected to the push handle 16; since the universal wheels 15 are installed at the four corners of the bottom of the box body 1, and the push handle 16 is fixedly installed on the outer wall of the box body 1, when in use, it is convenient for the staff to push the device to a suitable position; since the four groups of universal wheels 15 all have a self-locking structure, when the device is moved to a suitable position, the self-locking structure on the universal wheels 15 is used to conveniently fix the device at a suitable position; it should be noted that the universal wheel 15 with a self-locking structure is a prior art, so the specific working principle of the universal wheel 15 is not described in detail here.

[0030] The top of the box body 1 is fixed with a top cover 17 by four sets of fixing bolts 18; when the structure inside the box body 1 needs to be maintained and repaired, the four sets of fixing bolts 18 can be removed one by one using tools, and then the top cover 17 can be removed from the top of the box body 1, which is convenient for the staff to maintain and repair the structure inside the box body 1.

[0031] One end of the box body 1 away from the push handle 16 is connected to a curved tube 19, and the end of the curved tube 19 away from the box body 1 is connected to one end of a spring pipe 20, and the other end of the spring pipe 20 is connected to a curved tube 21, and the end of the curved tube 21 away from the spring pipe 20 is connected to a dust hood 22; when the device is in use, the dust hood 22 generates suction through the curved tube 19, the spring pipe 20 and the curved tube 21, and the dust sucked by the dust hood 22 enters the inner cavity of the box body 1 through the curved tube 21, the spring pipe 20 and the curved tube 19.

[0032] The outer wall of the bending tube 21 is fixedly connected to the lifting plate 23, and the inner side of the lifting plate 23 is threadedly connected with a screw 24, and the screw 24 is rotatably connected to the mounting frame 25 through two groups of bearings. A servo motor 26 is fixedly installed on the top of the mounting frame 25, and the driving end of the servo motor 26 is fixedly connected to one end of the screw 24. The mounting frame 25 is fixedly installed on the outer wall of the box body 1, and two groups of guide rods 27 are fixedly installed on the mounting frame 25. Both groups of guide rods 27 slide through the inner side of the lifting plate 23; when the device is in use, according to According to the specific situation of feeding, starting the servo motor 26 will drive the screw 24 to rotate, and the rotation of the screw 24 will drive the lifting plate 23 to move up and down along the two sets of guide rods 27. The up and down movement of the lifting plate 23 will drive the bending tube 21 to move up and down, and then move the dust hood 22 up and down to a suitable height; it should be noted that the servo motor 26 is a prior art, and adopts a self-locking structure and a driving force to install the servo motor 26 required by the device to avoid the screw 24 from rotating during use, thereby avoiding changing the height of the dust hood 22 during use.

[0033] A controller 28 is fixedly installed on the outer wall of the box body 1; when the device is in use, the device needs to be connected to a suitable external power supply to provide power support for the operation of the motor 1001 and the servo motor 26; and when the device is in use, the controller 28 controls the connection between the motor 1001 and the servo motor 26 through wires, and the operation of the motor 1001 and the servo motor 26 can be controlled by the controller 28.

[0034] The working principle of the present invention is as follows: when feeding, the device is pushed to a suitable position and stably stopped at a suitable position. Then, according to the specific situation of feeding, the servo motor 26 is started to drive the screw 24 to rotate. The rotation of the screw 24 drives the lifting plate 23 to move up and down along the two sets of guide rods 27. The lifting plate 23 moves up and down to drive the bending pipe 21 to move up and down, thereby moving the dust cover 22 up and down to a suitable height.

[0035] When the feeding process is in progress, the starting motor 1001 will drive the driving rod 1002 to rotate rapidly, and the rapid rotation of the driving rod 1002 will drive the blade 1004 to rotate. The blade 1004 rotates rapidly and passes through the filter tube 1 2 and the filter tube 2 3, so that the curved tube 19 generates suction, and then passes through the spring pipe 20 and the curved tube 2 21, so that the dust hood 22 generates suction. The dust sucked by the dust hood 22 will enter the inner cavity of the box 1 through the curved tube 21, the spring pipe 20 and the curved tube 1 19. After entering the inner cavity of the box 1, the air will first contact the filter screen 1 4. The filter screen 1 4 will filter out the larger dust in the air, and these larger dust will eventually fall into the collection box 1 13. The smaller dust in the air will pass through the filter holes of the filter screen 1 4, and then the filter screen 2 5 will filter out the remaining smaller dust in the air, and these dust will eventually fall into the collection box 2 14.

[0036] During the operation of the device, the driving rod 1002 rotates and under the transmission action of the two groups of sprockets 1005 and the chain 1006, the rotating shaft 6 is driven to rotate. The rotation of the rotating shaft 6 drives the two groups of gears 1 7 to rotate. The rotation of the two groups of gears 1 7 drives the two groups of gears 2 8 to rotate. The rotation of the two groups of gears 2 8 drives the filter tube 1 2 and the filter tube 2 3 to rotate respectively. The rotation of the filter tube 1 2 drives the filter screen 1 4 to rotate. The rotation of the filter tube 2 3 drives the filter screen 2 5 to rotate. When the filter screen rotates, the centrifugal force acts on the dust attached to the surface of the filter screen. This force pushes the dust away from the surface of the filter screen, helping to remove the dust attached to the filter screen. The rotation of the filter screen will cause friction between the filter screen and the dust. The friction can help loosen and peel off the dust attached to the surface of the filter screen, making it easier to remove. As a result, when the filter screen 1 4 and the filter screen 2 5 rotate, the dust attached to the surface of the filter screen 1 4 and the filter screen 2 5 can be separated, preventing the filter screen 1 4 and the filter screen 2 5 from being blocked by dust.

[0037] When the device is in use, the air in the box 1 will be discharged from the exhaust pipe 9. Since the aperture of the exhaust pipe 9 gradually decreases from one end to the other, the temperature of the air discharged from the exhaust pipe 9 will decrease, and the end with a smaller aperture of the exhaust pipe 9 is aligned with the motor 1001 in the drive assembly 10, the air discharged from the exhaust pipe 9 will blow toward the motor 1001, thereby accelerating the flow of air around the motor 1001, and the air discharged from the exhaust pipe 9 is relatively lower than the air around the motor 1001, thereby accelerating the heat dissipation of the motor 1001, so that the heat generated by the motor 1001 working for a long time can be evacuated; during the use of the device, after the valve 12 is opened, the air in the box 1 can also be discharged from the exhaust pipe 2 11. Since the air enters from the large hole and exits from the small hole, the temperature of the air discharged from the exhaust pipe 2 11 will decrease. At this time, the staff stands at the exhaust port of the exhaust pipe 2 11, and the exhausted air will blow toward the staff, which can slightly cool the staff.

[0038] It should be noted that the blades 1004 can be existing mature blades such as propeller blades and turbine blades, and when these blades rotate, they can generate suction in a disguised manner.

[0039] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as belonging to the scope of protection determined by the claims submitted for the present invention.
