Description

The Novel pneumatic jet dredge pump
Technical field
The utility model is a kind of pump, and particularly a kind of Novel pneumatic jet dredge pump is powdery material pneumatic conveying technology field.
Background technology
In the powdery material pneumatic transportation art, the storehouse pump has become Pneumatic conveyer commonly used, is one of main feedway of domestic and international malleation dense phase pneumatic conveying system, grey gas is arranged than the remarkable advantage high, that delivery speed is fast, fed distance is far away.But also there is its feedway auxiliary facilities many, the complicated thereby shortcoming of the large and intermittent delivery of investment once of control system, especially the operative employee will possess ripe control system operating experience, just can avoid because the disadvantages such as plugging that misoperation causes.
Chinese patent 98214703.1 discloses a kind of jet dredge pump.It has injection pump housing, links to each other with dust collector ash hopper in the injection pump housing upper end, and the middle part is provided with the discharging broadcast feeder, and the lower end is provided with the first half Venturi tube.Be provided with nozzle at first half Venturi tube convergent divergent channel open end center, side nozzle is taken over to be provided with and is blown down assembly and electromagnetic valve outside the injection pump housing lower end.This structure relative complex, and result of use is relatively poor, and use cost is high.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and compact conformation has simultaneously the mistake of air-flow consumption and lacks, and degree of vacuum is high, the Novel pneumatic jet dredge pump that transport efficiency is high.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of Novel pneumatic jet dredge pump, comprise blending box, the top of described blending box is provided with and is attached thereto logical material inlet, the left side of described blending box is provided with and is attached thereto logical injection orifice, the right side of described blending box is provided with and is attached thereto logical feeding port, be plugged with ring discharge in the described injection orifice, described ring discharge is connected with connection pipe, described connection pipe is connected with adjustment seat, described adjustment seat and connection pipe are fixedly connected by regulating sleeve, the head of described ring discharge extends to the below of material inlet, described feeding port is provided with the Venturi that is fixedly connected with it, described material inlet, the distribution that is connected of injection orifice and feeding port.
The air injection pump is to utilize strength principle of differential pressure and jet stream technology, fluidization technology combines, fully absorb the theory that modern strength is carried two phase flow, in short range powder pneumatic delivery technology system, overcome the defective of original air injection pump fed distance short (not super many 200 meters of equivalent length) and operational throughput little (operational throughput is no more than 25t/h).
Material inlet is finished balanced feed, and has a lock airway dysfunction, it is pressed into material in the low positive pressure system by normal pressure, ring discharge in the injection orifice, material and conveying gas uniform are mixed, material is sent to feeding port and enters in the Venturi, utilize strength pressure reduction to make material deliver to the material feeding destination along pipeline.Total is simple, moves very reliable.Ring discharge air-flow out is divergent contour.
Because adopt the form of carrying continuously, the transmitting power source of the gas generally adopts roots blower in addition, so power gas source generally need not set up cleanup system, only tolerance and pressure had certain requirement, can use compressor station source of the gas commonly used in independent source of the gas or the engineering.
As preferably, described ring discharge comprises nozzle holder, be provided with nozzle core in the described nozzle holder, described nozzle holder is located by nozzle body mutually with nozzle core, described connection pipe overcoat has duct sleeve, the sidewall of described duct sleeve and injection orifice fits, and described duct sleeve is by locking screw parent phase location.
As preferably, between described duct sleeve and connection pipe by the mutually sealing of O shape circle.
As preferably, described connection pipe and blending box are fixedly connected by spraying flange, and described Venturi and blending box fix by the feeding flange, and the top of described material inlet is provided with the feed flange.
As preferably, described injection orifice and feeding port are horizontal linear and distribute, and described material inlet is in vertical distribution between injection orifice and feeding port.
Therefore, the Novel pneumatic jet dredge pump that the utility model provides, compact conformation, reliable, carry and stablize, simple to operate, not high to the quality requirements of source of the gas, system reliability is high, economical rationality, cost is low, and systematic running cost is low.
