Abstract
The utility model provides a circular shape return-flow ventilation ground groove for solving the problems of not well-distributed whole aeration effect of a chamber storehouse, aeration dead corners of wall body area and among air channels, and dust stratification. Through the connection of a straight line air channel and a bending tail-end of the air channel, and the tangential connection of an air-return section and an inlet of a draught fan, the whole air channel takes a shape of a communicated smooth circular, eliminates the aeration dead corners of the wall body area and the phenomena of dust stratification and condensation in the air channel, and avoids the loss of gas-flow pressure in the air channel; continuity and stability of the wind power inside the groove still can be kept when a draught fan is used alone or powers of two draught fans are different.
Description
Technical field
The utility model relates to a kind of ventilation ground slot device, and especially a kind of grain chamber storehouse Bulk Grain is stored ventilated, dispelled the heat and fall the wet ring-like backflow ground slot device that ventilates.
Background technology
In order to prevent that heating from becoming damp and rotten, the method for taking usually is storage warehouse is ventilated, dispels the heat and to fall wet process by the ventilation geosyncline to grain in storage process.In the prior art, what the ventilation geosyncline adopted usually is a machine multiple tracks form.Though the geosyncline of this form is better in chamber storehouse central area ventilation effect, because one end sealing in air channel of the prior art causes the ventilation effect of wall body area very poor.During air-supply, this type of air channel must cause the inhomogeneous of the loss of pressure and blast at air inlet in branch air duct distributes and turns to.Simultaneously, this type of air channel forms local hyperbar at blind end, can cause dewfall under the relative humidity condition with higher, and at blind end and corner fouling phenomenon is arranged.
The utility model content
The purpose of this utility model is to adopt ring-like backflow ventilation geosyncline, guaranteeing on the even ventilation effect good basis in chamber storehouse central area, can solve the dead corner problem between whole ventilation effect problem of non-uniform, wall body area and each air channel and the dust stratification problem of corner.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme: a kind of ring-like backflow ventilation ground slot device comprises air distributor and connector in air channel, the air channel; It is characterized in that: two geosyncline air channels are passed through the chamber storehouse central area and are extended to opposite side from a side wall body straight line respectively, form ring-like perforation at the straightway end with the opposite side air channel at last, by tangentially being connected to the import in opposite side air channel, whole ventilation ground slot device is and is communicated with ring-like ventilation circuit at body of wall bend end in the air channel.
The linear pattern air channel is connected successively with the flexure type air channel.
The air channel is interconnected, and the blower fan connector can close separately or open.
The cross section in whole air channel is a uiform section.
Advantage of the present utility model is: whole air channel is interconnected, and constitutes ventilation circuit, has solved the fouling phenomenon in the dead corner that causes because of the air channel endcapped in the prior art, partial high pressure and the air channel; The tangential of connector links to each other, and makes whole air channel be smooth ring-like, and cross section is a uiform section, has guaranteed wind-force stability and the continuity in the air channel, solved the problem of stream pressure loss in the inhomogeneous and air channel of ventilation effect of the prior art.
Description of drawings
Fig. 1: working sections figure of the present utility model.
Fig. 2: the outside drawing of overlooking of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing:
Shown in Fig. 1 is sectional view under the utility model duty.Blower fan is by following air channel blowing earthward at the blower fan connector (1) on the ground level, when the wind of sending into when advance in the air channel, can be by installing air distributor (2) balanced ventilation earthward that feeds to the storage warehouse air draft in the air channel in advance.
Shown in Fig. 2 is the outside drawing of overlooking of the present utility model.The straightway in air channel is connected with the wall body area bending section is ring-like, has guaranteed continuity and the stability of wind-force in the air channel, avoids fouling phenomenon; Air return section tangentially is connected with straightway, and the residual compression of the wind that flows in the air channel is added in the new wind, has avoided the stream pressure loss in the machine multiple tracks air channel form; No bifurcated and obvious turning in the whole air channel.
The air channel is interconnected, and the blower fan connector can close separately and open, when only connecting a typhoon machine and closing another import or two typhoon acc powers simultaneously still can operate as normal.
Claims (4)
1, a kind of ring-like backflow ground slot device that ventilates, constitute by blower fan connector, linear pattern air channel, flexure type air channel and air distributor, it is characterized in that: two geosyncline air channels are passed through the chamber storehouse central area and are extended to opposite side from a side wall body straight line respectively, form ring-like perforation at the straightway end with the opposite side air channel at last; The air channel at body of wall bend end by tangentially being connected to the import in opposite side air channel; The whole ground slot device that ventilates is and is communicated with ring-like ventilation circuit.
2, according to a kind of ring-like backflow ventilation ground slot device described in the claim 1, it is characterized in that: the linear pattern air channel is connected successively with the flexure type air channel.
3, according to a kind of ring-like backflow ventilation ground slot device described in the claim 1, it is characterized in that: the blower fan connector can close separately and open.
4, according to a kind of ring-like backflow ventilation ground slot device described in the claim 1, it is characterized in that: the ventilating duct cross section of ventilation geosyncline is a uiform section.
