Description

Technical Field

[0001] The present invention belongs to the field of blower equipment, and particularly relates to a blower equipment with a novel chassis structure. Background Art

[0002] At present, for blower equipment on the market, especially those such as breeding fans in a rough environment, all components are often mixed and installed in a general cavity of the equipment chassis. These blower equipment sold on the market not only have an old-fashioned appearance, but also have various problems at present, mainly including: 1) Mixing and installing all components in one cavity makes installation and maintenance very troublesome. For example, when replacing the main unit, the frequency converter and some electronic components must be removed first; 2) The relevant electronic components used in the blower equipment and corrosive gases coexist in the same space, and their metal contact points are gradually corroded, seriously affecting the product life and performance; 3) After being affected by high temperature, the performance and life of the frequency converter are unstable; 4) The appearance of the chassis is old-fashioned and cannot give consumers a good visual experience. Summary of the Invention

[0003] The present invention aims to solve problems such as the electronic components being easily corroded after being mixed and installed in a chassis inner cavity, the trouble of installing and disassembling the frequency converter and the main unit, and the unstable performance of the frequency converter after high temperature.

[0004] A blower equipment with a novel chassis structure disclosed by the present invention includes a blower main unit, a frequency converter for controlling the output parameters of the main unit, a circuit breaker for controlling the power switch of the entire equipment, and other relevant electronic components; for the blower equipment with the novel chassis structure, all components are installed inside and outside a chassis, and the parts exposed outside the chassis include an air inlet of the blower equipment and an air outlet of the blower equipment opened as required. The internal space of the chassis of the blower equipment described in the present invention is divided into several spaces, and the blower main unit, the frequency converter, the circuit breaker, and the electronic components each have a space; in addition, there is also an aisle space, which is connected to the frequency converter space, and the air inlet pipe of the blower main unit is connected to the aisle space, ensuring that the air flow process of the entire blower equipment is as follows: the normal temperature air coming in from the outside first flows through the frequency converter space, and after flowing out of the frequency converter space, it enters the aisle space, which is the first turning point of the flow direction; after the air enters the aisle space, it is all sucked into the air inlet pipe of the blower main unit, which is the second turning point of the flow direction; finally, the air entering the air inlet pipe of the main unit is discharged from the air outlet pipe of the blower equipment. Using such a structure to guide the air flow can naturally take away the heat generated on the outer surfaces of the frequency converter and the main unit during operation, and play an obvious role in cooling the frequency converter and the related space.

[0005] Preferably, some scattered electronic components used in the blower equipment, including a touch screen, an emergency stop switch, signal lights, and other electronic components used, are installed in an independent space. The electronic component space is equipped with a Seal rotating door. After being sealed in this way, there is no gas exchange with the surrounding area, and the electronic components do not come into contact with external corrosive gases, which can be effectively protected, improving the service life of the electronic components and better exerting the product performance. Moreover, the electronic component space is close to the circuit breaker space, which is convenient for wiring and other issues.

[0006] Preferably, the separate space where the blower main unit is located, although there are air outlets of the blower equipment and openings for placing the inlet air duct of the main unit, there is no gas exchange between the entire space where the blower main unit is located and other surrounding spaces; and sound insulation components are installed on the inner walls of each side of the space where the blower main unit is placed, and / or on the top of the frequency converter space inside the chassis. Such a design, on the one hand, prevents the heat in the main unit space from being transferred to the frequency converter space, can also specifically insulate sound, and has a very good noise reduction effect. And the air inside the blower main unit remains relatively clean and is not interfered by the external space.

[0007] Preferably, air inlets are opened on the three vertical side surfaces of the frequency converter space, and there is no opening on the top of the chassis to prevent dust from falling.

[0008] Specifically, when the air inlet of the blower main unit cannot reach the aisle space, an additional air duct is connected and then connected to the aisle space to ensure that there is no air exchange between the blower main unit space and the surrounding space and the air inlet and outlet inside the main unit. All the air entering the aisle space is sucked into the inlet air duct of the main unit and then discharged.

[0009] Optionally, among the components exposed outside the chassis, there is also an externally extended outlet air duct connected according to actual needs.

[0010] Specifically, the blower main unit uses air suspension bearings, which belongs to an air suspension blower equipment with a novel chassis structure. Therefore, filter components are equipped for each air inlet of the blower equipment in the frequency converter space to meet the working environment required by the air suspension bearings.

[0011] Preferably, the four columns of the box body adopt columns with a large arc shape, which are more novel and beautiful from the whole to the part.

[0012] Optionally, according to actual needs, alarm signals can be set for the control system of the blower equipment, and corresponding alarm lights are equipped outside the chassis.

[0013] The blower equipment with the above novel chassis structure has the following advantages: 1. The air entering the chassis from the outside forms a unique air flow due to the unique space arrangement, enabling the frequency converter to obtain natural air cooling, stabilizing the performance of the frequency converter and best exerting its service life; 2. The frequency converter and the blower main unit are arranged in their respective independent spaces, so that the installation and disassembly do not interfere with each other, and operations such as debugging and maintenance are more convenient; 3. The electronic components are installed in an independent enclosed space, and it is not easy for external corrosive gases to enter. The electronic components do not contact external corrosive gases, can be effectively protected, the service life of the electronic components is prolonged, and the product performance is better exerted; 4. The design of the small internal space of the chassis makes it easier to obtain better effects in noise reduction, filtration, etc. of the entire equipment; 5. The shape of the large arc columns of the chassis makes the appearance of the equipment more novel and beautiful from the whole to the part. Description of the Drawings

[0015] A blower device with a novel chassis structure disclosed in this embodiment, as Figure 1 shown, includes a blower main unit 1, a frequency converter 2 for controlling the output parameters of the main unit, a circuit breaker 4 for controlling the power switch of the entire device, and other related electronic components 3; for the blower device with a novel chassis structure, all components are installed inside and outside a chassis 7, and what is exposed outside the chassis 7 includes an air inlet 5 of the blower device opened as required and an air outlet pipe 6 of the blower device, as Figure 2 shown.

[0016] The internal space of the chassis of the blower device in this embodiment, as Figure 3 and 4 shown, is divided into several spaces, and the blower main unit 1, the frequency converter 2, the circuit breaker 4, and the electronic components 3 each have a space; there is also an aisle space 9, the aisle space 9 communicates with the frequency converter space 8, and the air inlet pipe 15 of the blower main unit extends into the aisle space 9; as Figure 1 shown, the air inlet 5 of the blower device is opened on the side of the frequency converter space 8, and in this embodiment, the air inlets 5 of the blower device are opened on three sides.

[0017] The air flow process of the entire blower device is as follows: The normal temperature air coming in from the outside first flows through the frequency converter space 8, and after flowing out of the frequency converter space 8, as Figure 3 shown at the first flow turning point 11, it enters the aisle space 9; after the air enters the aisle space 9, as Figure 4 shown at the second flow turning point 12, it is sucked into the air inlet pipe 15 of the blower main unit; finally, the air entering the main unit air inlet pipe 15 is discharged from the air outlet pipe 6 of the blower device. In this embodiment, the air flow is guided in such a structural manner, which can naturally carry away the heat generated when the frequency converter 2 and the main unit 1 work, and play an obvious role in cooling the frequency converter 2 and its related space.

[0018] In this embodiment, there is no air circulation in the aisle space 9 relative to the blower main unit space 10, and the frequency converter space 8 relative to the blower main unit space 10, so that the heat of the blower main unit 1 can also be restricted from affecting the components in other spaces. As Figure 1 and 2 shown, there is no gas exchange between the electronic component space 13 and the surroundings, so that the electronic components 3 sealed in a separate space can be protected from the erosion of the external air flow.

[0019] In addition, inside the blower main unit 1 of this embodiment, air suspension bearings are installed, so it is an air suspension blower device with a novel chassis structure. For this reason, as Figure 4As shown, at the air inlet 5 of each blower device on the frequency converter space 8, a filter assembly is arranged to protect the clean working environment required by the air suspension bearing. In addition, the separate space where the blower main unit 1 is located, such as Figure 4 As shown, although there are openings 17 for placing the outlet duct of the blower device and opening 18 for placing the inlet duct 15 of the blower main unit, after placing the outlet duct 6 of the blower device and the inlet duct 15 of the main unit, there is no gas exchange between the space where the entire blower main unit 1 is located and other surrounding spaces. And sound-absorbing components are arranged on the inner walls of the blower main unit space 10. This is not only to reduce the noise of the blower device, but also conducive to the dust-free working environment required by the air suspension bearing and to extend the service life of the device.

[0020] Since the inlet duct 15 of the blower main unit 1 itself in this embodiment is too short, the air inlet of the blower main unit cannot reach the opening 18 for placing the inlet duct of the main unit. Therefore, a guide duct 16 is added, as Figure 1 As shown, it extends into the aisle space 9 to enable all the air from the frequency converter space 8 to be taken into the inlet duct of the main unit.

[0021] In this embodiment, the appearance of the chassis 7 is also beautified. It adopts a large arc cylinder, as Figure 4 As shown; and, according to the actual requirements of the blower, an alarm setting is made in the system of this embodiment, and corresponding alarm lights 20 are configured at prominent positions outside the chassis 7, as Figure 1 As shown.

[0022] The product in the above embodiment overcomes several substantial defects of the old products sold on the current market, improves the actual effects of the product in several aspects, makes the performance of the entire device stable, and gives full play to the best service life; the noise is reduced, including the configuration of the alarm light, making the user experience comfortable; the disassembly and installation for maintenance and repair are convenient; the appearance of the product, from the whole to the part, is more novel and beautiful.
