Description

Technical Field

[0001] The utility model relates to the technical field of fan box assembly, in particular to a fan box shell that is easy to disassemble and assemble. Background Art

[0002] Industrial fans play a core role in ventilation and air exchange. They can effectively expel polluted air from the factory and introduce clean air at the same time, thereby significantly improving indoor air quality. In addition, fans can also remove exhaust gas from factory workshops and buildings, which helps to purify the air and protect the environment. When fans are used in air purification equipment such as air filters and fume purifiers, they can remove harmful substances such as suspended particles, smoke and odors, providing people with healthier indoor air. When fans are used for a long time and in large quantities, the internal components of the fan, such as the filter, will fall into a lot of dust and need to be cleaned regularly to improve the performance of the fan. At this time, staff need to disassemble the fan for operation.

[0003] However, most existing industrial fans have some common problems in disassembly and assembly, whether during production or maintenance and replacement:

[0004] 1. When it is necessary to dismantle and clean a fan that has been working for a long time, it is very inconvenient to dismantle the doors on the left and right sides of the fan box. Sometimes the fan needs to be moved out of the original installation site before the outer doors of the fan box can be opened. This results in high maintenance costs and low efficiency.

[0005] 2. The volute of the fan is the core part of the fan, where the turbine and motor are located. It is also the place where the electrical components of the fan are prone to failure. In fact, in actual use scenarios, when the volute needs to be removed from the fan casing, the original installation and fixing method is very firm, and due to years of disrepair, the nuts, bolts and volute are rusted and corroded, making it very difficult to disassemble and assemble the volute.

[0006] In summary, a fan housing that is easy to disassemble and assemble is proposed to solve the above problems. Utility Model Content

[0028] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example 1:

The base plate 1 and the upper top plate 4 are both rectangular structures. The four corners of the base plate 1 and the upper top plate 4 are fixedly connected with connecting parts 9. Four frames 5 are arranged between the base plate 1 and the upper top plate 4. The upper and lower ends of the four frames 5 are respectively fixedly connected with docking parts 10. The four docking parts 10 at the bottom are matched one by one with the connecting parts 9 at the four corners of the base plate 1.

It should be noted that the bending angle of the sheet metal often fluctuates within the range of ±5° according to actual needs, among which the 135° bending angle is the optimal bending angle of this structure and is relatively easy to achieve. If a bending angle of 135° fluctuating within the range of ±5° is adopted, the actual operation difficulty will be increased.

[0032] In addition, the upper plate e905, upper plate c903 and upper plate b902 are integrally formed by a bending process without being disconnected in the middle;

[0033] Please combine Figure 7 and Figure 9 As shown, the docking member 10 includes a lower plate a501, a lower plate b502 and a lower plate c503 respectively fixedly connected to one end of the frame 5, one side of the lower plate a501 abuts against one side of the lower plate b502, the lower plate a501 and the lower plate b502 are 135 degrees, and one side of the lower plate b502 is fixedly connected to the lower plate c503, the lower plate c503 and the lower plate b502 are 135 degrees of sheet metal bending, and the upper end of the lower plate b502 is fixedly connected to the lower plate d504, and the lower plate d504 and the lower plate b502 are 135 degrees of sheet metal bending; through the cooperation of the lower plates a501, the lower plates b502 and the lower plates c503 with the various components in the connecting member 9, not only is it convenient for the production stage, the staff can quickly install and fix it, but also a large number of screws can be saved, reducing costs.

[0040] The implementation principle of an easy-to-disassemble fan box casing in the embodiment of the present application is as follows: in the actual use scenario of the fan, it is often necessary to maintain and service the fan, such as cleaning dust or replacing electrical parts in the fan. At this time, the fan needs to be disassembled on site. If the fan is difficult to disassemble on site and the fan needs to be moved out of the site as a whole, the cost of disassembling and maintaining the fan is too high, which is not realistic and not convenient for the staff to use. Therefore, a method is needed that is easy to use on site, and the volute 8 can be pulled out and maintained from the fan base plate 1 by simply opening the left and right door panels 6 of the fan. The corners of the base plate 1 and the upper top plate 4 of the fan casing are fixedly connected with connecting parts 9, and a frame 5 is provided between the base plate 1 and the upper top plate 4. Docking parts 10 are connected at both ends of multiple frames 5 to form a match with the connecting parts 9. The connecting parts 9 and the docking parts 10 are provided with mutually matching screw holes. The threaded bolts inside the mutually matching screw holes are used to achieve fixed connection between the frame 5 and the upper and lower base plates 1 and the upper top plate 4, thereby realizing the construction of the overall frame of the fan casing. The left and right door panels 6 and the front and rear door panels 7 arranged on the periphery can be quickly fixed by simply inserting bolts from the outside through the pre-reserved threaded holes. In addition, a bayonet 15 is provided on the volute 8, which can be plugged in with the conical block 13, and the other end of the conical block 13 is fixedly connected to the L-shaped baffle 12 through the positioning bolt 11, thereby realizing the rapid fixation and disassembly of the volute 8 on the base plate 1, which is convenient for the operator to use later.

[0041] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
