Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal devices, and in particular relates to a dust removal device with a double-turbine powerful fan and a cyclone nozzle. Background Art

[0002] With the vigorous development of new energy vehicles and the rapid development of lithium battery technology, the dust on the lithium battery electrodes has become one of the key processes and techniques that must be removed in the production process. Domestic and foreign cyclone or tornado dust removal devices have good dust removal effects and have become one of the mainstream products.

[0003] Patent application number 202321121512.4 discloses a tornado-type dust removal and static removal device. The rotating nozzle assembly of the device will rotate at high speed under the drive of the first drive motor and blow out gas from the nozzle. The rotating gas will generate a tornado-like airflow, which can blow out dust and the like on the IGBT module, and float continuously with the tornado-like airflow. During the process, the left ion wind rod and the right ion wind rod will also be started to ionize and remove static electricity from the tornado-like airflow. After the dust removal and static removal process of the IGBT module is completed, the exhaust device is started to extract the airflow through the gap between the inner and outer purge covers. Since an external workshop air source is required as the input source of the cyclone or tornado, the gas consumption is usually relatively large, which to a certain extent limits the application of such devices.

[0026] This specific embodiment is a dust removal device with a double-turbine powerful fan and a cyclone nozzle, and its structural diagram is as follows Figure 1-Figure 5 As shown, the dust removal device includes a main shell 1, and a cover plate 2 is fixedly connected to the left and right sides of the main shell 1. A cavity 3 is opened inside the main shell 1 and a dual-turbo powerful fan 4 is installed. The upper surface of the main shell 1 is provided with an air inlet 5 connected to the dual-turbo powerful fan 4, and the lower surface of the main shell 1 is provided with an air outlet 6 connected to the dual-turbo powerful fan 4. A cyclone nozzle 7 is installed at the output end of the dual-turbo powerful fan 4. The cyclone nozzle 7 is used to generate a circular cyclone. Specifically, each dual-turbo powerful fan 4 is equipped with a cyclone nozzle 7, and the negative pressure interface 8 and the dual-turbo powerful fan 4 are connected to the main shell 1. The dual-turbo powerful fan 4 is used to generate a strong straight wind.

[0027] The upper surface of the main housing 1 is provided with a negative pressure interface 8 connected to the air outlet 6. The main housing 1 includes an inner housing and an outer housing. The negative pressure interface 8 is connected to an external dust collector. The external dust collector can extract the airflow through the gap between the inner housing and the outer housing. This is the prior art and will not be described in detail.

[0028] The cyclone nozzle 7 includes a connecting cavity 9, a cyclone center plate 10 is provided in the middle of the connecting cavity 9, a plurality of cyclone guide plates 11 are installed between the cyclone center plate 10 and the inner wall of the connecting cavity 9, and a cyclone outlet 12 is formed between two adjacent cyclone guide plates 11.

[0029] like Figure 1 and Figure 2 As shown: In this embodiment, the number of cavities 3 and dual-turbo powerful fans 4 are three. The dual-turbo powerful fan 4 is connected to the external power supply through a voltage speed regulator. Since the powerful fan power line is externally connected to the 220V lighting power supply and is connected in series with a voltage speed regulator, it can generate a powerful axial wind of up to 30,000 rpm, which makes it very convenient to use and control. The power wire of the dual-turbo powerful fan 4 passes through the notch on the back of the fan and comes out from the top. The wires of the three dual-turbo powerful fans 4 are marked and bundled for centralized routing.

[0030] like Figure 1 and Figure 2 As shown: In this embodiment, there are two negative pressure interfaces 8, and the two negative pressure interfaces 8 are located between the three air inlets 5. One end of the negative pressure interface 8 is fixedly connected to the main shell 1 by a first screw 13, and the other end of the negative pressure interface 8 is used to connect to the external dust collection integrator. There is a sealing gasket between the negative pressure interface 8 and the main shell 1 to avoid air leakage, so that the external dust collector can better draw away the airflow and the dust removal effect is better.

[0031] like Figure 1 and Figure 3 As shown: In this embodiment, the cover plate 2 is fixedly connected to the main shell 1 by a second screw 14, and a sealing gasket is provided between the cover plate 2 and the main shell 1 to avoid air leakage, so that a vacuum negative pressure chamber can be formed, and negative pressure can be formed with the integrator connected to the negative pressure interface 8.

[0032] In order to make the installation of the dual turbo powerful fan 4 more convenient, Figure 1 and Figure 3 As shown: In this embodiment, the dual-turbo powerful fan 4 is fixedly connected to the main housing 1 through a third screw 15.

[0033] like Figure 1 and Figure 2 As shown: In this embodiment, the cyclone center plate 10 is fixedly connected to the output shaft of the dual-turbo powerful fan 4, and can be fixed by screws, so that the dual-turbo powerful fan 4 is directly connected to the cyclone nozzle 7, which better drives the cyclone nozzle 7 to rotate and form a powerful cyclone.

[0034] like Figure 4 and Figure 5As shown: In this embodiment, the cyclone guide plates 11 are inclined and there are twelve of them. The cyclone guide plates 11 are fixedly connected to the cyclone center plate 10 through angle adjustment locking screws 16, and the cyclone guide plates 11 are fixedly connected to the connecting cavity 9 through angle adjustment locking bolts 17. The angle adjustment locking screws 16 and the angle adjustment locking bolts 17 are used to adjust the different angles of the cyclone guide plates 11 to form cyclones with different inclination angles.

[0035] Specifically, long holes are opened on both ends of the cyclone guide plate 11. The position of the cyclone guide plate 11 can be adjusted by the angle adjustment locking screw 16 and the angle adjustment locking bolt 17, so that the cyclone angle of the cyclone nozzle 7 can be adjusted, thereby forming a reasonable dust removal wind speed and cyclone effect.

[0036] Working principle: when in use, first install three dual-turbo powerful fans 4 on the main shell 1, then install two negative pressure interfaces 8, and finally install two cover plates 2 at both ends, and then the dual-turbo powerful fans 4 are externally connected to the 220V lighting power supply. After the voltage speed regulator can continuously adjust the speed, it can generate a strong axial wind of up to 30,000 revolutions per minute. After the strong axial wind enters through the air inlet 5, it is guided along the cyclone guide plate 11 at the air outlet 6 to form a cyclone output with a certain inclination angle. The generated strong cyclone is ejected from the cyclone outlet 12 and acts on the dust-removed medium. At the same time, the negative pressure of the integrator connected to the negative pressure interface 8 can be continuously adjusted to form a balanced convection flow field with the cyclone without air leakage. Since the strong cyclone is formed by the cooperation of the dual-turbo powerful fans 4 and the cyclone nozzle 7, there is no need for an external workshop air source as the input source of the cyclone or tornado, which greatly improves the application of this type of device.

[0037] like Figure 6 and Figure 7 As shown in the figure, spherical copper powder particles with a particle size of 5um are sprinkled on the surface of the graphite pole piece of the lithium battery of a new energy vehicle. The comparison chart of the effects before and after dust removal shows that the dust removal rate reaches more than 99%, which is very good and fully meets user needs.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
