The propeller casting dryer is characterized in that an air cooler and a control cabinet are respectively mounted on a base by flanges, the air cooler is connected with an electric heating furnace by an induced air pipe, and a control circuit is mounted in the control cabinet and respectively connected with the induced draft fan and the electric heating furnace. By the aid of the propeller casting mold dryer, heat is saved, drying speed is increased, the propeller casting mold dryer is favorable for pouring and exhausting, and all heated surfaces in a cavity are heated uniformly and have small temperature difference. In addition, proper temperature of the inside of the cavity can be controlled according to pouring technical requirements, and the pouring quality is guaranteed. Furthermore, pollution to working environments is prevented during hot air drying, residuals in the casting cavity are eliminated, and labor intensity of workers is relieved.
Description
Technical field
The utility model belongs to casting mould drying field, relates in particular to a kind of screw mould drying machine.
Background technology
At present; Such device is often adopted in the screw mould drying: comprise that electric calorifie installation and air-introduced machine are fixed on operation control on the base; Adopt horizontal type structure on the structure; The hot blast of 5 φ 75mm of configuration is carried active fast interface on the flange of air outlet, through P3 type metal hose hot blast is delivered to casting mold inside and carries out mould drying.But use this device to have following problem: 1, this dryer power is too little, and power can't regulate, and the heat energy utilization rate is not high.2, owing to distance between metal mold flexible pipe and the sand mold is big, thermal losses is big, causes the mould drying temperature that gets into casting mold die cavity inside not meet the demands, and the mould drying time is oversize, consequently influences the production cycle of screw.
Summary of the invention
The utility model problem to be solved is to overcome the above-mentioned defective that aforementioned techniques exists, and a kind of screw mould drying machine that provides:
A kind of screw mould drying machine; Comprise base, switch board, air-cooler, electrothermal furnace; Base is provided with adpting flange; Through flange air-cooler and switch board are installed in respectively on the base, air-cooler is connected with induced duct with electrothermal furnace, control circuit is housed in the switch board is connected with electrothermal furnace with air-introduced machine respectively.
Electrothermal tube two ends in the electrothermal furnace are fixedly connected with tube sheet and put into the electric heating bobbin carriage, and cover plate is connected with the electric heating bobbin carriage with screw, and tube sheet and furnace chamber inside isolate with heat-insulation layer.
Described air-cooler separates with electrothermal furnace, and induced duct is arranged at cold junction.
In the air inlet of electrothermal furnace wind pressure sensor is housed, temperature sensor is housed in the air outlet.
Described air inlet is similar with the mould drying shape with the induced duct joint geometry with the air outlet shape.
Described electrothermal furnace is vertical state and is directly installed on top, propeller shaft shell mould chamber.
Described electric heating bobbin carriage is independently, can single taking-up or installation.
1～20 electric heating bobbin carriage is set in the described electrothermal furnace.
Electrothermal tube in the described electric heating bobbin carriage is set to 10～100.
Described air inlet and air outlet profile can be according to induced duct joint geometry and mould drying alterations of form.
Screw mould drying machine is equipped with wind pressure sensor in the described air inlet, and temperature sensor is housed in the air outlet.Cold wind gets into electrothermal furnace from air inlet, through electrothermal tube heating back from the air outlet mo(U)ld face to be dried of flowing through.Wind pressure sensor detects the blast at air inlet place, and temperature sensor detects the temperature at place, air port, the protection electrothermal tube.
The utility model compared with prior art has significant advantage and beneficial effect:
The utility model adopts the split design, and air-introduced machine is separated with electrothermal furnace, moves on to cold junction to induced duct from the hot junction.It is vertical that electrothermal furnace adopts, and is directly installed on top, propeller shaft shell mould chamber, saved the heat when casting mold appearance and sandbox etc. are not needed the heating part oven dry.Hot blast with certain pressure in the die cavity to outer heating, promptly can accelerate dry speed, can make each several part core and part back-up sand in the die cavity, lute, asbestos cord etc. fully dry again, keep certain heat, it is unimpeded that type, core are given vent to anger, and helps pouring into a mould exhaust.Because hot blast is the thermal current of one continuous-flow, thereby each heating surface very evenly has a narrow range of temperature in the die cavity.Casting mold and loam core can not be out of shape and crack, and the quality that casting pouring is shaped is guaranteed.Screw mould drying machine utilizes phase-shift trigger circuit that controllable silicon is regulated, but the stepless change power output is big or small, when normal operation, carries out control automatically.Whole heating process is carried out to high temperature by low temperature in proper order, and can require preference temperature in the control die cavity according to pouring technology, guarantees casting quality.Hot-blast stove is easy to use, and is simple to operate, arbitrarily moves.Pollution-free to working environment when baking, noresidue in the casting mold die cavity has alleviated working strength of workers.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done to detail further:
Fig. 1 is the electrothermal furnace structural representation of the utility model.
Fig. 2 is the overall appearance structural representation of the utility model
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment,, specify as the back the specific embodiment, structure, characteristic and the effect thereof that provides according to utility model:
See also Fig. 2, a kind of screw mould drying machine comprises base 1, switch board 2, air-cooler 3, electrothermal furnace 4.Base 1 is provided with adpting flange, through flange air-cooler 3 and switch board 2 is installed on the base 1, and air-cooler 3 is connected with electrothermal furnace 4 usefulness induced ducts, control circuit is housed in the switch board 2 is connected with electrothermal furnace 4 with air-introduced machine 3 respectively.See Fig. 1: cold wind gets into electrothermal furnaces 4 from air inlet 5, through electrothermal tube 10 heating backs from air outlet 9 mo(U)ld face to be dried of flowing through.Wind pressure sensor 12 detects the blast at air inlet 5 places; Temperature sensor 13 detects the temperature at 9 places, air port; Electrothermal tube 10 two ends are fixedly connected with tube sheet 8 and put into electric heating bobbin carriage 7, and cover plate 11 usefulness screws are connected with electric heating bobbin carriage 7, and tube sheet 8 is isolated with heat-insulation layer 6 with furnace chamber is inner.
