Abstract
The invention relates to a venturi tube used for a bag-type deduster. The venturi tube comprises an end face part (1), a contracted tube part (2), a throat diameter part (3), and an expanded tube part (4). The end face part (1) is connected to the contracted tube part (2), the throat diameter part (3), and the expanded tube part (4) in order. The contracted tube part (2) is equipped with through holes (5) and baffle plates (6). Compared with the prior art, the venturi tube provided in the invention has the advantages of: greatly increasing the filtering passage area of the bag-type deduster, substantially reducing the resistance, and improving the economic benefits, etc.
Description
Technical field
The present invention relates to a kind of Venturi tube, especially relate to a kind of Venturi tube for bag type dust collector.
Background technology
Venturi tube mainly use with sack cleaner in, it utilizes the variation of gas pressure to make Compressed Gas in the gas bag (minute gas tank) jet in the air chamber of sack cleaner and the solid dust that is attached on the filtering material is broken away from, compressed air spraying is accelerated by Venturi tube draw partial velocity, pressure decreased, be easy to cause Secondary Flow gas, by after the throat by the enlarged tube portion supercharging of slowing down again, steady by the gas pressure behind the Venturi tube, 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 widely treating flour dust and assembling sphere with every profession and trade.
Existing Venturi tube comprises end face part 1, draw part 2, larynx path portion 3, enlarged tube portion 4 etc. as shown in Figure 1.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
Purpose of the present invention is exactly to provide a kind of filtration channel area of sack cleaner that makes greatly to increase for the defective that overcomes above-mentioned prior art existence, and resistance reduces greatly, the Venturi tube for bag type dust collector of increasing economic efficiency.
Purpose of the present invention can be achieved through the following technical solutions: a kind of Venturi tube for bag type dust collector, 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 present invention 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, the filtration channel area of sack cleaner is increased greatly, resistance reduces greatly, and deduster and applying unit are had very large economic benefit.
Description of drawings
Fig. 1 is the structural representation of existing Venturi tube;
Fig. 2 is the structural representation of Venturi tube of the present invention.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 2, compressed air spraying is accelerated by draw partial velocity, pressure decreased, be easy to cause Secondary Flow gas, by after the throat by the enlarged tube portion supercharging of slowing down again, steady by the gas pressure behind the Venturi tube, speed is even, deashing to sack cleaner plays a very important role, Venturi tube for bag type dust collector of the present invention, comprise end face part 1, draw part 2, larynx path portion 3, enlarged tube portion 4, end face part 1 connects draw part 2 successively, larynx path portion 3 and enlarged tube portion 4, 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, its shape can be geometry or the irregular geometry of rule, such as 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 form 0～90 degree angle with draw part 2 sidewalls, and block 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, resistance reduces greatly, and deduster and applying unit are had very large economic benefit.
