Technical field
The utility model relates to a kind of injection apparatus, is specifically related to a kind of spray repair agent quantitative conveyer.
Background technology
Gun is mainly used in gunning refractory, spray paint half-dried spray repair in steel plant's Thermal Equipment of refractory material.Gun has been widely applied in electric-arc furnace steelmaking production.Gun is formed primarily of air supply system, tank body, spraying system three part.
Existing gun mainly comprises batch can, cylinder, taper valve core, conical valve seat, Connection Block, air intake valve and shower nozzle, cylinder is installed in batch can, the piston rod of cylinder is connected with taper valve core, conical valve seat is installed on bottom batch can, and in conical valve seat, be provided with the tapping channel run through, taper valve core and conical valve seat cone match, Connection Block is connected with conical valve seat, also the material road run through is provided with in Connection Block, the outlet of Connection Block is connected with shower nozzle, shower nozzle has hybrid chamber, hybrid chamber Nei You mono-road water under high pressure passes through, to form negative pressure in hybrid chamber, by the spray repair agent sucking-off in batch can.
Whether the spray repair agent of existing gun supplies, and is decided by the gap folding between taper valve core and conical valve seat, and taper valve core carries out folding under cylinder drives.When cylinder moves downward, valve port closes, and cuts off spray repair agent supply; When cylinder moves up, valve port is opened, and spray repair agent is under suction function, and arrive hybrid chamber, and form gunning refractory after mixing with water under high pressure, the size of gunning refractory flow is relevant with the negative pressure of the circular cone annular gap size between spool and valve seat and hybrid chamber.But the shortcoming of this structure is: be difficult to the load and the discharging speed that control spray repair agent in batch can, so uneven from the gunning refractory of gun shower nozzle ejection.
Utility model content
For the defect that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of load and the discharging speed that can control spray repair agent in batch can, thus from the gunning refractory uniform spray repair agent quantitative conveyer that gun shower nozzle sprays.
For achieving the above object, the technical solution of the utility model is: spray repair agent quantitative conveyer, comprise the batch can of bottom belt discharging opening, conical valve seat, Connection Block, flexible pipe and shower nozzle, described batch can upper portion side wall is provided with charging aperture, and charging aperture is provided with hopper, described conical valve seat is arranged in Connection Block, material road is provided with in Connection Block, and Connection Block is connected with bottom batch can, the material road outlet of Connection Block is connected by described flexible pipe with shower nozzle, wherein, also be provided with discharging mechanism, described discharging mechanism comprises stepper motor, screw rod, mount pad and sealing shroud, described stepper motor is fixed in batch can, and the output of stepper motor is connected with screw rod, described mount pad is connected to batch can bottom discharge mouth position, be placed in described sealing shroud in mount pad, and sealing shroud is provided with the through hole coordinating screw rod, this through hole is relative with discharging opening.
When adopting technique scheme, spray repair agent adds material bin, and falls into batch can from hopper, starts stepper motor, because the output of stepper motor is connected with screw rod, so stepper motor drives bolt rotary, again because mount pad is connected to batch can bottom discharge mouth position, be placed in sealing shroud in mount pad, and sealing shroud is provided with the through hole coordinating screw rod, this through hole is relative with discharging opening, so spray repair agent is under the turning effort of screw rod, spray repair agent is sent continuously from the groove of the spiral of screw rod, and fall into conical valve seat, conical valve seat is arranged in Connection Block, material road is provided with in Connection Block, and the outlet of the material road of Connection Block is connected by described flexible pipe with shower nozzle, so spray repair agent is in the effect Xia Jingliao road of negative pressure, flexible pipe enters in the hybrid chamber of shower nozzle, spray after mixing with water under high pressure.In the utility model, bolt rotary, spray repair agent is sent, and screw rod is connected with the output of stepper motor, so the discharging speed of spray repair agent in batch can is determined by the rotating speed of stepper motor, only need the velocity of rotation of control step motor, just can control load and the discharging speed of spray repair agent in batch can, thus even from the gunning refractory of gun shower nozzle ejection.
Further, tapered funnel-form bottom described batch can, the spray repair agent bottom batch can be made bottom the batch can of conical hopper shape all to send, and spray repair agent is without accumulation.
Further, described Connection Block is provided with the air equalizer opening be obliquely installed, when screw rod discharging speed is slower, the hybrid chamber of shower nozzle forms negative pressure can make flexible pipe be out of shape, hinder the discharging of spray repair agent on the contrary, and the air equalizer opening on Connection Block can avoid the pressure differential between hybrid chamber and flexible pipe too large, so the deflection of flexible pipe can be reduced, be convenient to the smooth discharging of spray repair agent.
Further, described sealing shroud is threaded with mount pad, in bolt rotary process, and continuous frictional between sealing shroud, sealing shroud easily weares and teares, and sealing shroud is threaded with mount pad, is convenient to the sealing shroud changing wearing and tearing.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model spray repair agent quantitative conveyer embodiment.
Detailed description of the invention
