Abstract
The utility model provides a novel centrifugal ventilator. The utility model is characterized in that an adapting flange is welded on the inner side of the end surface of a casing; a front cover plate for an air inlet is inlaid in a circular hole of the casing, and is connected and fixed with a weld nut on the adapting flange through a bolt; a welded flange is welded into a whole with a streamline air outlet of the casing, a frame is made of steel plates, a vane wheel in the casing is installed on a motor shaft of a motor, and the motor and the casing are fixed on the base through the bolts; the air outlet is connected with the welded flange in an electric welding way. The utility model has the advantages of favorable air tightness, high air blow efficiency and favorable stability; besides, the utility model is safe; as laser cutting is adopted, product precision is high, processing technic is simple, and the appearance of the entire centrifugal ventilator is compact and beautiful.
Description
The utility model relates to the novel centrifugal ventilator.
Mainly contain two class formations at present: a class is the form of traditional standard just.Another kind of special fan is to form through remodeling manufacturing on the basis of standard type; The blower fan of remodeling at the exhaust outlet place with external one, two of welded flanges or four exhaust outlet independently.This form had both been wasted raw material, manufactured loaded down with trivial detailsly, and again to the mobile resistance that increased of high pressure draught, and because the intake grill front shroud is fixed by bolts to the casing end face outside, sealing is poor, thereby has reduced air-supply efficient.
The purpose of this utility model is in order to provide a kind of exhaust outlet and fan casing to be made into an integral body, and its air channel is made streamlined, has so just reduced resistance, is convenient to high pressure draught and flows.Owing to adpting flange is welded on casing end face inboard, and the intake grill front shroud embeds in the circular hole of casing end face, has strengthened sealability, thereby improves air-supply efficient, the simplicity generosity that complete machine is shown.In addition, support selects for use the steel plate manufacturing of respective thickness to form, the stability when having increased the blower fan working state like this, and what is more important has been taked laser beam machining, technology for blanking, and it is more easy to make product manufacture, and the product accuracy of manufacturing is higher.
The utility model is achieved through the following technical solutions, the novel centrifugal ventilator, and it has motor, intake grill front shroud, welded flange, exhaust outlet, adpting flange, support, and its main points are that adpting flange is welded on casing end face inboard; The intake grill front shroud embeds in the casing circular hole and is connected and fixed with the welded nut on bolt and the adpting flange, and the fusiform wind outlet of welded flange and casing is welded into one; Support is made by steel plate, and the impeller in the casing is installed on the motor shaft of motor, and motor is fixed by bolts on the support, and casing is fixed by bolts on the support, and exhaust outlet is connected with the welded flange electric welding.The exhaust outlet of blower fan can be positioned at the left of blower fan, right-hand or top.Exhaust outlet can be one, two, three, four.The cutting process of the component of novel centrifugal ventilator adopts laser beam machining.
The utility model has the advantages that: the one, reasonable in design, adpting flange is welded on casing end face inboard, and the intake grill front shroud embeds in the circular hole of casing end face, tightness is good, air-supply efficient height; The 2nd, select the steel plate of respective thickness for use and adopt the laser cutting technique manufacturing to form, good stability, safe and reliable, manufacture simple, machine shape is succinctly attractive in appearance.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the plan view of Fig. 1.
With reference to the accompanying drawings the utility model is elaborated below.
The novel centrifugal ventilator, it has motor 6, intake grill front shroud 2, welded flange 4, exhaust outlet 5, adpting flange 9, support 7, and its main points are that adpting flange 9 is welded on casing 1 ' end face inboard; Intake grill front shroud 2 embeds in casing 1 circular hole and is connected and fixed with the welded nut on bolt and the adpting flange 9, and welded flange 4 is welded into one with casing 1 fusiform wind outlet; Support 7 is made by steel plate, and the impeller 8 in the casing 1 is installed on the motor shaft of motor 6, and motor 6 is fixed by bolts on the support 7, and casing 1 is fixed by bolts on the support 7, and exhaust outlet 5 is connected with welded flange 4 electric welding.The exhaust outlet 5 of blower fan can be positioned at the left of blower fan, right-hand or top.Exhaust outlet 5 can be one, two, three, four.The cutting process of the component of centrifugal blower adopts laser beam machining.
During manufacturing, process various component with laser beam cutting machinery, order is installed and is got final product as stated above.The intake grill place can be according to different needs by dress protective net or air filter during use.Exhaust outlet is connected with plastic film capicitor one end, and the other end of bellows is connected with molding machine, carpenter, chemical machinery.High pressure draught is sent into corresponding mechanism through plastic film capicitor.
