Description
Technical field
The present invention relates to a kind of gasification nozzle, be specially a kind of gasification nozzle with a backstop role.
Background technology
Strength is carried the every field that is widely used in national products such as electric power, metallurgy, chemical industry, grain, building materials in recent years, draws formula concentrated phase strength transmission pump down and is widelyd popularize because of its efficient, energy-conservation characteristics again.Because adopt the bottom discharge mode, fluidization of material is unreasonable, very easily stop up behind the entering delivery duct.
At present, the way that adopts the pump bottom to add vaporizing chamber promotes the fluidization of material more.This kind mode is prone to make the undue fluidization of material, causes that the conveying solid-gas ratio is low excessively, increases energy consumption; As containing bulk metal, be prone to cause breaking of vaporizing chamber in the material, and material causes vaporizing chamber to stop up after getting into vaporizing chamber, loses gasification; In addition, gasification also lacks the actv. control device.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of gasification nozzle with a backstop role is provided.
According to technical scheme provided by the invention, said gasification nozzle with a backstop role comprises joint, sleeve, nozzle cover and connecting rod; Joint has negative thread, and the top outer wall of sleeve has outside thread, and the bottom of joint and the top of sleeve are screwed into one; The top inwall of sleeve has interior step, and on interior step, sitting has spring perch, spring perch axially offer mounting hole; In mounting hole, be plugged with described connecting rod; Described connecting rod has connecting rod epimere, connecting rod stage casing and connecting rod hypomere, and described connecting rod epimere has cavity with cooperating of mounting hole, and described connecting rod stage casing and mounting hole are free-running fit; The connecting rod hypomere is installed with described nozzle cover through captive nut, and the bottom of nozzle cover and sleeve offsets; Be bolted with setting nut at the connecting rod epimere, on the connecting rod between setting nut and the spring perch, be socketed with spring.
Connecting rod epimere below setting nut is bolted with stop nut, the range that stop nut and spring perch offset and move down with limiting rod.
Be circular conical surface in order to the position that offsets with the sleeve bottom on the said nozzle cover.
The present invention relies on pressure reduction self-opening in pipeline and the pump, realizes gasification, and SELF CL during out of reach pressure reduction avoids gasification installation in running order always; The present invention can change the pressure difference that nozzle is opened through the adjusting of top spring; The present invention relies on action of the spring, can prevent after nozzle is closed that material from blowing back into nozzle; The mode that the present invention adopts top to introduce is avoided being broken by bulk materials; The present invention adopts threaded connection, can conveniently regulate the height of nozzle distance pump bottom.
Description of drawings
Fig. 1 is an integral structure scheme drawing of the present invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure, said gasification nozzle with a backstop role comprises joint 3, sleeve 8, nozzle cover 6 and connecting rod 7; Joint 3 has negative thread, and the top outer wall of sleeve 8 has outside thread, and the top of the bottom of joint 3 and sleeve 8 is spirally connected and is one; The top inwall of sleeve 8 has interior step 10, and on interior step, sitting has spring perch 11, spring perch 11 axially offer mounting hole 12; In mounting hole 12, be plugged with described connecting rod 7; Described connecting rod 7 has connecting rod epimere, connecting rod stage casing and connecting rod hypomere, and described connecting rod epimere has cavity with cooperating of mounting hole 12, and described connecting rod stage casing and mounting hole 12 are free-running fit; The connecting rod hypomere is installed with described nozzle cover 6 through captive nut 5, and nozzle cover 6 offsets with the bottom of sleeve 8; Be bolted with setting nut 1 at the connecting rod epimere, on the connecting rod 7 between setting nut 1 and the spring perch 11, be socketed with spring 9.
Connecting rod epimere below setting nut 1 is bolted with stop nut 4, the range that stop nut 4 and spring perch 11 offset and move down with limiting rod 7.
Be circular conical surface in order to the position that offsets with sleeve 8 bottoms on the said nozzle cover 6.
The nozzle cover 6 of this nozzle is fixed on the connecting rod 7 through captive nut 5, and setting nut 1, stop nut 4 and spring 8 are equipped with in the top of connecting rod 7, and connecting rod 7 is plugged in the mounting hole 12 of sleeve 8.Sleeve 8 and nozzle cover 6 contact surfaces rely on spring 9 tightening forces to keep sealing through processing, prevent the material refluence, and through regulating the tensile force that setting nut 1 can change spring 9, open required pressure thereby change nozzle cover 6.Joint 3 is threaded with sleeve 8 usefulness, through the length of adjustment connecting thread, can adjust the height of nozzle distance pump bottom.
Principle of work of the present invention:
The present invention is that a kind of tensile force of spring 9 that relies on is implemented in self-opening sleeve 8 and nozzle cover 6 under certain pressure reduction; Make the connecting rod stage casing skid off mounting hole 12 downwards; The connecting rod epimere slips into mounting hole 12; Because the connecting rod epimere has cavity with cooperating of mounting hole 12, fluid just can flow to the space of opening between sleeve 8 and the nozzle cover 6 from the chamber between connecting rod epimere and the mounting hole 12.Perhaps SELF CL sleeve 8 and nozzle cover 6 under certain pressure reduction are adjusted the gasification nozzle of blowdown of a safety valve through setting nut 1 regulating spring 9 tensile force sizes, and can under the effect of the tensile force of spring 9, prevent that material from flowing backwards.
