Description

Technical Field

[0001] The utility model relates to an industrial fan. Background Art

[0002] Industrial fans are often used for vacuuming. Pipes are laid in the workshop, and then an industrial fan is set up outside. The pipes are connected to the fan, and the impeller of the centrifugal fan rotates, driving the dust in the pipe into the pipe and finally into the dust collection bag or environmental protection equipment for dust treatment. Since the pipes in each workshop cannot be laid at a uniform height, the fan sometimes cannot completely match the pipe in height. Nowadays, bricks, wooden blocks, etc. are often placed at the bottom of the fan frame. This placement can also solve the height problem, but there will be different heights. After all, artificial raising cannot guarantee the uniformity of height. If the height is not uniform, the impeller will also have different heights, which will affect the operation effect of the fan. Utility Model Content

[0003] The utility model mainly solves the technical problems existing in the prior art, thereby providing an industrial fan which can be finely adjusted in height and has a simple structure.

[0004] The above technical problems of the present invention are mainly solved by the following technical solutions:

[0005] The utility model discloses an industrial fan, comprising a frame and a fuselage and a motor respectively arranged on the frame; the frame comprises a lower frame and an upper frame which can move up and down; a plurality of side support members are evenly arranged on both sides of the upper and lower frames; a fixing column is respectively arranged on one side of the side support member, and a support block is sleeved on the fixing column.

[0006] Preferably, the side support member is a U-shaped structure, with a top cover at the upper end, a support plate provided in the middle position, and a lower end fixedly connected to the side of the lower frame.

[0007] Preferably, outwardly protruding side panels are respectively provided at positions on the side edges of the upper frame corresponding to the side support members.

[0008] Preferably, a plurality of support blocks are sleeved on the upper and lower sides of the fixing column; and the support blocks can rotate along the fixing column.

[0009] The beneficial effects of the utility model are:

[0010] Through the design of the side support members, the upper shelf can be adjusted flexibly, and the height is limited, and it will not detach or deviate. Besides, through the design of simple support blocks and fixed columns next to the side support members, the distance between the upper and lower shelves can be adjusted by stacking different support blocks, thereby adjusting the overall height of the fan; the fan of the present application can achieve fine-tuning of the height; and this structure is simple, the production cost is low, and it can ensure the stability of the upper shelf and ensure the safety of the fan when the height is adjustable.

[0015] In the figure: 1-frame, 2-motor, 3-body, 1.1-lower frame, 1.2-upper frame, 1.3-side support, 1.4-support block, 1.5-fixing column, 1.6-side plate, 1.7-support plate DETAILED DESCRIPTION

[0016] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0017] like Figure 1 As shown, an industrial fan, mainly used for vacuuming, is capable of finely adjusting the height. It comprises a frame 1, a body 3 and a motor respectively mounted on the frame 1. It should be noted that the other structures and principles of the fan in this application are the same as those of existing industrial centrifugal fans, so the applicant does not describe other parts of the fan in detail here.

[0018] The frame 1 includes a lower frame 1.1 and an upper frame 1.2 that can move up and down; a plurality of side support members 1.3 are evenly arranged on both sides of the upper and lower frames; specifically, the lower end of the side support member 1.3 is fixed to the side of the lower frame 1.1, and the upper frame 1.2 can move up and down along the side support member 1.3. The side support member 1.3 is the movable guide component of the upper frame 1.2 and also the component that connects the upper and lower frames together; a fixing column 1.5 is respectively provided on one side of the side support member 1.3, and a support block 1.4 is mounted on the fixing column 1.5; further, the fixing columns 1.5 are also evenly distributed on one side of the side support member 1.3.

[0019] The side support member 1.3 is a U-shaped structure, with a top cover (not marked) at the upper end, a support plate 1.7 provided in the middle, and a lower end fixedly connected to the side of the lower frame 1.1.

[0020] Outwardly protruding side panels 1.6 are respectively provided at positions on the sides of the upper frame 1.2 corresponding to the side support members 1.3; further, the side panels 1.6 are placed on the support plates 1.7, so that the upper frame 1.2 is fixed above the lower frame 1.1, and there is a certain gap between the upper and lower frames. When moving the fan, a forklift can be inserted between the upper and lower frames to lift the fan for movement; when the forklift is inserted between the upper and lower frames to lift it, the upper frame 1.2 will eventually hit the top cover of the side support member 1.3 and cannot move further upward.

[0021] Multiple support blocks 1.4 are sleeved above and below the fixed column 1.5; these support blocks 1.4 are rotatable along the fixed column 1.5. Furthermore, once the blower is positioned to the desired location, its height can be adjusted to a certain degree based on the height of the duct. The blower is connected to the vacuum duct. If there is a small height error, the upper shelf 1.2 is raised with a forklift, and the support blocks 1.4 are rotated so that they are positioned between the upper and lower shelves. The upper shelf 1.2 is then lowered to be supported by the support blocks 1.4. Different numbers of support blocks 1.4 can be stacked to achieve different heights for the upper shelf 1.2.

[0022] The beneficial effects of the utility model are:

[0023] Through the design of the side support members, the upper shelf can be adjusted flexibly, and the height is limited, and it will not detach or deviate. Besides, through the design of simple support blocks and fixed columns next to the side support members, the distance between the upper and lower shelves can be adjusted by stacking different support blocks, thereby adjusting the overall height of the fan; the fan of the present application can achieve fine-tuning of the height; and this structure is simple, the production cost is low, and it can ensure the stability of the upper shelf and ensure the safety of the fan when the height is adjustable.
