Abstract
The utility model provides a negative-pressure induction nozzle, which comprises a tube body, wherein the outer side of the bottom part of the tube body is provided with a nozzle, and is characterized in that two sides of the nozzle are respectively provided with an induction hole. Two induction holes are arranged in the negative pressure area of the nozzle straight tube, so the air volume anticipating the spraying is greatly increased, the air volume entering the filter bag through the pulse spray is greatly increased, the ash removal capacity of the bag-type dust collector is improved, and the ash removal effect of the filter bag is increased.
Description
Technical field
The utility model relates to a kind of negative pressure-induced nozzle, is used for sack-duster pulse blowing.
Background technology
Present winding-up pipe adopts tubular structure, is made up of the nozzle of butt end, body and straight pipe type, and butt end adopts the mode of welding to be connected with body, body with nozzle.The nozzle of straight pipe type is the simple secondary gas flow of inducing the drainage filter bag opening when pulse jet, and the secondary gas flow of inducing is less, the tolerance that influence enters filter bag, and reduce the deashing ability of sack cleaner and the ash-removal effect of filter bag.
Summary of the invention
The purpose of this utility model provides a kind of pulse jet and enters that filter bag tolerance is bigger, sack cleaner deashing ability is bigger, the negative pressure-induced nozzle of filter bag ash removal better effects if.
In order to achieve the above object, technical approach of the present utility model has provided a kind of negative pressure-induced nozzle, comprises body, and the bottom outside of body is provided with nozzle, it is characterized in that, the both sides of nozzle respectively are provided with one and induce the hole.
The utility model is provided with two at nozzle straight tube negative pressuren zone and induces the hole, makes the large-minded big increase that participates in winding-up, has significantly increased pulse jet and has entered the tolerance of filter bag, thereby improved the deashing ability of sack cleaner, has strengthened the ash-removal effect of filter bag.
Description of drawings
A kind of negative pressure-induced structure of nozzle schematic diagram that Fig. 1 provides for the utility model.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, a kind of negative pressure-induced structure of nozzle schematic diagram that provides for the utility model is by body 1, nozzle 2 and induce hole 3 to form.
During use, air-flow flow into nozzle 2 straight tubes from body 1, because the air-flow velocity that passes through nozzle 2 straight tubes is near velocity of sound, so can manage on body 1 bearing of trend perpendicular to winding-up at nozzle 2 straight tubes and produce negative pressuren zone, be provided with two at negative pressuren zone and induce hole 3, induce the drainage secondary gas flow to participate in pulse jet.
In the process of sack-duster pulse blowing, when pulse valve is opened rapidly, Compressed Gas was released in moment, air-flow is after power conversion is finished in winding-up pipe inside, high velocity air enters nozzle 2 straight tubes, because the air-flow velocity that passes through nozzle 2 straight tubes near velocity of sound, produces negative pressuren zone so can manage on body 1 bearing of trend perpendicular to winding-up at nozzle 2 straight tubes, therefore offer and induce hole 3, help inducing the secondary gas flow of drainage negative pressuren zone to participate in pulse jet.
Claims (1)
1. a negative pressure-induced nozzle comprises body (1), and the bottom outside of body (1) is provided with nozzle (2), it is characterized in that, respectively is provided with one in the both sides of nozzle (2) and induces hole (3).
