Description
Technical Field
The utility model relates to a centrifugal smoke exhaust fan.
Background
The existing smoke exhaust fan is generally influenced by high temperature and surrounding environment, and an exhaust hood at the top of the smoke exhaust fan is easy to corrode and damage, so that rainwater enters the fan, and the fan is damaged; in addition, when the exhaust hood is replaced, the exhaust hood must be communicated with the outer shell to be replaced together, which is waste.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a smoke exhaust fan solves the technical problem who how to redesign smoke exhaust fan and play the smoke exhaust effect.
The smoke exhaust fan comprises a mounting plate, an impeller, a fixed sleeve, an outer shell, a protective cover, a filter element piece and a hub fixed porous support; the mounting plate is connected with the hub fixing porous support through a fixing sleeve, and an air inlet hole is formed in the mounting plate in a hollow mode; the hub fixing porous support is connected with the outer shell; the impeller is fixed on the hub fixing porous support; the protective cover is movably matched with the top of the outer shell; a filter element is arranged between the protective cover and the fixed sleeve; the mounting plate is integrally square; the blades in the impeller are centrifugal fan blades; the number of the fixed sleeves is multiple, and a ventilation gap is formed between every two adjacent fixed sleeves; the outer shell is a stainless steel outer shell; the protective cover is a stainless steel rain-proof cap; the filter element is filled with dust-removing filter cotton.
The mounting plate is a stainless steel mounting plate.
The outer shell is composed of two hollow cylinders with different diameters, wherein the diameter of the cylinder at the top is smaller than that of the cylinder at the top.
The filter element has a pull handle thereon.
The utility model has the advantages that: through the optimized design, the movable matching of the protective cover and the outer shell is met, so that the replacement of a single protective cover is very convenient, and the cost is low; the strength requirement of the whole device is met by designing the fixing sleeve; through the design of the filter element, dust removal treatment is carried out on the dust-containing gas, and the requirement of environmental protection is met.

Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a top view of the impeller;
in the figure, 1, a mounting plate, 2, an impeller, 3, a fixed sleeve, 4, an outer shell, 5, a protective cover, 6, a filter element, 7, a hub fixed porous support and 8, a drawing handle are arranged.
Detailed Description
Referring to fig. 1 and 2, the smoke exhaust fan includes a mounting plate 1, an impeller 2, a plurality of fixing sleeves 3, an outer casing 4, a protecting cover 5, a filter element 6, and a hub fixing porous bracket 7.
The mounting plate 1 is integrally made of stainless steel and is connected with a hub fixing porous support 7 through a fixing sleeve 3, and an air inlet hole is formed in the mounting plate 1 in a hollow mode; through such configuration guarantee air inlet other parts of well fixing simultaneously. The mounting plate 1 is designed to be square, and can also be designed to be round in specific application.
The impeller 2 is a conventional centrifugal fan assembly. Which mainly plays a role of drawing indoor air out and guiding the air to the outside so as to purify the indoor air.
The fixing sleeve 3 is an existing mature part, and the hub fixing porous support 7 and the mounting plate are fixedly connected together through the upper end and the lower end of the fixing sleeve with screws. The number of the fixed sleeves 3 is multiple, the upper half section between the adjacent fixed sleeves 3 is provided with a ventilation gap, and the lower half section is closed, so that a smooth ventilation channel is formed.
The whole stainless steel that adopts of shell body 4, its structure is inside hollow structure, and it constitutes for the hollow cylinder of two different diameters, and wherein the diameter of the cylinder at top is less than the diameter of the cylinder at top. With such a design, a small part is used to provide space for the motor and a large part is used to provide space for the induced wind.
The protective cover 5 is made of stainless steel integrally and is of a cylindrical structure integrally, and the protective cover 5 is matched with the outer shell 4 by adopting a buckle or other conventional modes such as a pressing clamp and the like.
The filter element 6 is a filter element with dust removing effect, which is arranged between the outer casing 4 and the fixing sleeve 3, and the filter element 6 is filled with filter cotton. In order to facilitate the filling of the filter element 6 between the outer casing 4 and the fixing sleeve 3, a drawing handle 8 can be fitted to the filter element 6, which facilitates handling.
The hub fixing porous support 9 is of a common support structure, mounting holes are formed in the positions, matched with the fixing sleeves 3, of the hub fixing porous support, and therefore screws penetrate through the mounting holes to be matched with the fixing sleeves 3, the hub fixing porous support 9 is matched with the mounting plate 1, and meanwhile the fan and the hub assembly 2 are also fixed on the hub fixing porous support 9.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the above description, in combination with the drawings in the embodiments of the present invention, clearly and completely describes the technical solutions in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the above detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
