Abstract
The utility model relates to a low-resistance Venturi tube for a bag dust remover. The low-resistance Venturi tube comprises an end surface part (1), a pipe reduction part (2), a throat radius part (3) and a pipe expansion part (4), wherein the end surface part (1) is connected with the pipe reduction part (2), the throat radius part (3) and the pipe expansion part (4) in sequence; and a through hole (5) and a baffle (6) are arranged on the pipe reduction part (2). Compared with the prior art, the utility model has the advantages that the area of a filtering passage of the bag dust remover is greatly increased, the resistance is greatly reduced, and the economic benefits are improved.
Description
Technical field
The utility model relates to a kind of Venturi tube, especially relates to a kind of sack cleaner and uses the lower resistance Venturi tube.
Background technology
Venturi tube mainly use with sack cleaner in; It utilizes variation of gas pressure to make Compressed Gas in the gas bag (branch gas tank) jet in the air chamber of sack cleaner and make attached to the solid dust on the filtering material to break away from; Compressed air spraying is accelerated through Venturi tube draw partial velocity, and pressure reduces, and is easy to cause Secondary Flow gas; Through after the throat by the enlarged tube portion supercharging of slowing down again; Gas pressure through behind the Venturi tube is steady, and speed is even, and it is the crucial accessory of sack cleaner that the deashing of sack cleaner is played a very important role.Use treating flour dust and assembling sphere widely with every profession and trade.
Existing Venturi tube is as shown in Figure 1, comprises end face part 1, draw part 2, larynx path portion 3, enlarged tube portion 4 etc.But because Venturi tube has the larynx path portion, this is exactly the aisle spare that has reduced when filtering work for sack cleaner, and this will increase equipment resistance greatly, cause the difficulty of design and the increasing of fund input.
Summary of the invention
The purpose of the utility model is exactly to provide a kind of filtration channel area of sack cleaner that makes to increase greatly for the defective that overcomes above-mentioned prior art existence, and resistance reduces greatly, and the sack cleaner of increasing economic efficiency is used the lower resistance Venturi tube.
The purpose of the utility model can realize through following technical scheme: a kind of sack cleaner is used the lower resistance Venturi tube; Comprise end face part 1, draw part 2, larynx path portion 3, enlarged tube portion 4; End face part 1 connects draw part 2, larynx path portion 3 and enlarged tube portion 4 successively; It is characterized in that described draw part 2 has through hole 5 and baffle plate 6.
Described through hole 5 is arranged on draw part 2 sidewalls, and described baffle plate 6 one ends are arranged on through hole 5 one sides, and the other end extends along draw airflow direction, and forms 0～90 degree angle with draw part 2 sidewalls.
Described baffle plate 6 forms angle with draw part 2 sidewalls, and blocks through hole 5.
Described through hole 5 is shaped as circle, square, triangle or rhombus.
Described through hole 5 is provided with at least one.
Compared with prior art; The utility model partly has through hole at the Venturi tube draw; Prolong draw direction on the through hole and be provided with baffle plate, the effect of baffle plate is directly to flow out from through hole when stoping air flow blowing, and the filtration channel area of sack cleaner is increased greatly; Resistance reduces greatly, and deduster and applying unit are had very big economic benefit.
Description of drawings
Fig. 1 is the structural representation of existing Venturi tube;
Fig. 2 is the structural representation of the utility model Venturi tube.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 2, compressed air spraying is accelerated through draw partial velocity, and pressure reduces; Be easy to cause Secondary Flow gas, through after the throat by the enlarged tube portion supercharging of slowing down again, steady through the gas pressure behind the Venturi tube; Speed is even; Deashing to sack cleaner plays a very important role, and the utility model sack cleaner is used the lower resistance Venturi tube, comprises end face part 1, draw part 2, larynx path portion 3, enlarged tube portion 4; End face part 1 connects draw part 2, larynx path portion 3 and enlarged tube portion 4 successively, described draw part 2 have three through holes 5 and with through hole 5 baffle plate 6 one to one.Described through hole 5 is arranged on draw part 2 sidewalls, and its shape can be geometry or the irregular geometry of rule, like circular, square, triangle or rhombus; Described baffle plate 6 one ends are arranged on through hole 5 one sides; The other end extends along draw airflow direction, and forms 0～90 degree angle with draw part 2 sidewalls, and blocks through hole 5; The effect of baffle plate is directly to flow out from through hole when stoping air flow blowing; The filtration channel area of sack cleaner is increased greatly, and resistance reduces greatly, and deduster and applying unit are had very big economic benefit.
