Background technology
Charcoal glue pump is the specific equipment that is pressed into the plain material of charcoal when being used for blast furnace maintenance.Because there is the slit in the refractory brick of blast furnace in building process, the High Temperature Gas in the production process in the stove is known from experience excessive along this slit, causes the furnace body outer wall temperature to raise.This just need with charcoal glue pump to State of Blast Furnace at the bottom of, position such as cupola well and iron mouth carries out continuous mud jacking operation, the plain material of charcoal is pressed in the refractory brick slit, to fill up this type of space, prevent that warm air is excessive along this slit in the body of heater, furnace wall temperature is controlled within the scope of design.
General charcoal glue pump comprises mono-pump, transmission system, motor, hopper, electric control box and base etc., and motor drives the mono-pump operation by transmission system, and mono-pump is pressed into the plain material of charcoal blast furnace or gets back to hopper through the feed back pipe by three-way diverter valve.Find that through actual job this charcoal glue pump output pressure is difficult to control, all can exert an influence, cause operator can't accurately control output pressure maintenance and equipment.Operate in this case and may produce following two kinds of problems: 1. output pressure is low excessively, can not guarantee that the body of heater corresponding site is pressed into the plain material of enough charcoals, and the refractory brick slit is not filled up fully, and grouting result does not reach the specification of quality of maintenance; 2. output pressure continues to surpass rated pressure, and the screw rod of the pump housing (rotor) abrasive conditions increases the weight of, and the spot corrosion of the about 2～3mm of diameter appears in screw surface, causes excessive clearance between stator and the rotor, and system pressure reduces, and shorten work-ing life greatly; Stator liner, each sealing member and barrier film are because system pressure raises, and wearing and tearing strengthen, also corresponding shortening of life-span.Usually the plain material of charcoal needs to be heated to 90 ℃ before being pressed into simultaneously, to guarantee the viscosity and the flowability of material.Therefore the plain material of the charcoal in the hopper is the slurry through heating, and in some cases, the plain material of charcoal pressurizes but fails to be pressed in the blast furnace brickwork joint or through reversing valve through the long period and is back to hopper by the feed back pipe, at this moment the temperature of slurry obviously reduces, influence its normal viscosity and flowability, influenced the grouting result of blast furnace.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of specific equipment charcoal glue pump that is used for blast furnace maintenance, this charcoal glue pump can be done output pressure control and slurry heating, avoided output pressure too high or too low and slurry temperature is lower and the defective that causes, guarantee the blast furnace grouting result, prolonged service life of equipment.
For solving the problems of the technologies described above, the specific equipment charcoal glue pump that the utility model is used for blast furnace maintenance comprises motor, transmission system, spiral pump, three-way diverter valve, the feed back pipe, hopper and control device, described motor connects described spiral pump by transmission system, described screw rod delivery side of pump is provided with described three-way diverter valve, described three-way diverter valve one end connects delivery hose, its the other end connects described feed back Guan Yiduan, the other end of described feed back pipe inserts described hopper, the delivery port of described hopper connects the input aperture of described spiral pump, and described control device connects described electric machine control motor operation by lead; This charcoal glue pump also comprises electro connecting pressure gauge and electric heater, the pressure end of described electro connecting pressure gauge connects the hydraulic efficiency system output terminal of described spiral pump, its electric contact connects described control device by lead and is used to control described motor operation, and described electric heater is located at described hopper bottom and is heated slurry in the described hopper by described control device.
Further, above-mentioned electro connecting pressure gauge is that diaphragm type magnetic helps electro connecting pressure gauge.
For guaranteeing the reliability of reversing valve, above-mentioned three-way diverter valve is the three-way diverter valve of stainless steel.
Because the specific equipment charcoal glue pump that the utility model is used for blast furnace maintenance has adopted technique scheme, promptly on the basis of former charcoal glue pump, install an electro connecting pressure gauge additional at the hydraulic efficiency system output terminal of spiral pump, be used to monitor the output pressure of pump and controlled; Simultaneously the hopper bottom be provided with electric heater and by control device to hopper in slurry implement heating; This charcoal glue pump can do output pressure control and slurry heats, and has avoided output pressure too high or too low and slurry temperature is lower and the defective that causes has guaranteed the blast furnace grouting result, has prolonged service life of equipment.
