Description
Technical field
The utility model relates to a kind of gasification nozzle, is 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 after 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 easily makes the undue fluidization of material, causes that the conveying solid-gas ratio is low excessively, increases energy consumption; As containing bulk metal, easily cause breaking of vaporizing chamber in the material, and material causes vaporizing chamber to stop up after entering vaporizing chamber, loses gasification; In addition, gasification also lacks the actv. control device.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of gasification nozzle with a backstop role is provided.
The technical scheme that provides according to the utility model, described gasification nozzle with a backstop role, comprise joint, sleeve, nozzle cover and connecting rod, joint has negative thread, the top outer wall of sleeve has outside thread, the bottom of joint and the top of sleeve are screwed into one, the top inwall of sleeve has interior step, on interior step, sit spring perch is arranged, spring perch axially offer mounting hole, in mounting hole, be plugged with described connecting rod, described connecting rod has the connecting rod epimere, connecting rod stage casing and connecting rod hypomere, 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 by 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 described nozzle cover.
The utility model relies on pressure reduction self-opening in pipeline and the pump, realize gasifying, and SELF CL during out of reach pressure reduction avoids gasification installation in running order always; The utility model can change the pressure difference that nozzle is opened by the adjusting of top spring; The utility model relies on action of the spring, can prevent after nozzle is closed that material from blowing back into nozzle; The mode that the utility model adopts top to introduce is avoided being broken by bulk materials; The utility model 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 utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, described gasification nozzle with a backstop role, comprise joint 3, sleeve 8, nozzle cover 6 and connecting rod 7, joint 3 has negative thread, the top outer wall of sleeve 8 has outside thread, 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, on interior step, sit spring perch 11 is arranged, spring perch 11 axially offer mounting hole 12, in mounting hole 12, be plugged with described connecting rod 7, described connecting rod 7 has the connecting rod epimere, connecting rod stage casing and connecting rod hypomere, 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 by 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 described nozzle cover 6.
The nozzle cover 6 of this nozzle is fixed on the connecting rod 7 by 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 by 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, by adjusting the length of connecting thread, can adjust the height of nozzle distance pump bottom.
Principle of work of the present utility model:
The utility model 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 by setting nut 1 regulating spring 9 tensile force sizes, and can prevent that material from flowing backwards under the effect of the tensile force of spring 9.
