Abstract
The utility model discloses a bag-type dust remover blowback nozzle, which comprises a cylindrical nozzle main body, wherein a blind hole is coaxially arranged on one end surface of the nozzle main body, and a conical outer distributor is coaxially and fixedly arranged on the other end surface of the nozzle main body; the center of the bottom of the blind hole is provided with a conical inner distributor, and the bottom of the blind hole around the inner distributor is provided with more than three air holes in an evenly distributed manner. Has the advantages that: compared with the prior art, the nozzle is internally provided with the built-in distribution cone, compressed gas is distributed through the distribution cone, the problem that the jet distance is lengthened is solved, and the kinetic energy ineffective loss of compressed air is reduced. The air fluid is diffused from four sides by utilizing the inner pipe diameter distribution structure of the nozzle to form reverse blowing in a straight line shape at four sides, so that the abrasion of the upper part of the cloth bag is effectively reduced.
Description
The technical field is as follows:
the utility model relates to a sack cleaner blowback nozzle belongs to the corollary equipment of sack cleaner.
Background art:
the existing 4-6m bag-type dust collector has the disadvantages of scattered back blowing, direct back blowing and direct blowing of 2-3m, poor back blowing effect, bag back blowing pressure abrasion in the upper 1m range, short effective service time of the bag and ineffective consumption of compressed air accounting for 50 percent, and the compressed air is directly injected by adopting a 16mm straight pipe by utilizing 0.4MPa compressed air.
The utility model has the following contents:
an object of the utility model is to provide a sack cleaner blowback nozzle that makes blowback fluid from four sides diffusion, reduces the invalid loss of blowback compressed air kinetic energy
The utility model discloses by following technical scheme implement: the bag-type dust collector back-blowing nozzle comprises a cylindrical nozzle main body, wherein a blind hole is coaxially formed in one end face of the nozzle main body, and a conical outer cloth distributor is coaxially and fixedly arranged on the other end face of the nozzle main body; the center of the bottom of the blind hole is provided with a conical inner distributor, and the bottom of the blind hole around the inner distributor is provided with more than three air holes in an evenly distributed manner.
Preferably, the included angle between the axis of the air hole and the axis of the blind hole is half of the cone angle of the inner distributor.
The utility model has the advantages that: compared with the prior art, the nozzle is internally provided with the built-in distribution cone, compressed gas is distributed through the distribution cone, the problem that the jet distance is lengthened is solved, and the kinetic energy ineffective loss of compressed air is reduced. The air fluid is diffused from four sides by utilizing the inner pipe diameter distribution structure of the nozzle to form reverse blowing in a straight line shape at four sides, so that the abrasion of the upper part of the cloth bag is effectively reduced.
Description of the drawings:
fig. 1 is a front view of the present invention.
Fig. 2 is a bottom view of fig. 1.
Fig. 3 is a top view of fig. 1.
Fig. 4 is a structural sectional view of the present invention.
The specific implementation mode is as follows:
example (b): as shown in fig. 1 to 4, the bag-type dust collector blowback nozzle comprises a cylindrical nozzle body 1, a blind hole 2 is coaxially arranged on one end surface of the nozzle body 1, and a conical outer distributor 3 is coaxially and fixedly arranged on the other end surface of the nozzle body 1; a conical inner distributor 4 is arranged in the center of the bottom of the blind hole 2, and four air holes 5 are uniformly distributed in the bottom of the blind hole 2 around the inner distributor 4; the included angle alpha between the axis of the air hole 5 and the axis of the blind hole 2 is half of the cone angle of the inner distributor 4.
Instructions for use: the bag-type dust collector back-blowing nozzle is arranged at a branch pipe nozzle of a bag-type dust collector back-blowing distributor, compressed air enters a nozzle main body, and the compressed air passes through a conical distributor; the compressed air is distributed uniformly and then flows to the nozzle outlet through the air hole to enter the cloth bag chamber for back flushing.
