Wax solution, jet chimney stretches into dewaxed solution, and high-temperature steam is imported dewaxed solution by jet chimney, and temperature detect switch (TDS) controls steam pipe
The air inflow in road.Separately there is lifting basket to take up wax-pattern, promote basket and wax-pattern together immerses in dewaxed solution.
In prior art, hot-water dewaxing device is disadvantageous in that: (1) high-temperature steam heating dewaxed solution causes solution
Local boiling, dewaxed solution content is easily generated liquid convection, and the sand grains being deposited on dewaxing trench bottom is involved in mould by the solution of convection current
The inner chamber of shell, causes follow-up foundry goods to produce sand holes, affects casting quality；(2) the increasing sand of bottom deposit of dewaxing groove
Grain, it is necessary to routine cleaning, cleans dewaxing groove and then must empty dewaxed solution, stop dewaxing work, affect the production efficiency of foundry goods.
Utility model content
The technical problems to be solved in the utility model is that the hot-water dewaxing device of prior art is easily caused formwork inner chamber folder
Sand and production efficiency are low.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of hot-water dewaxing device, including taking off
Wax cylinder and heater, contain dewaxed solution, heater installed by dewaxing cylinder in dewaxing cylinder, heater is used for heating dewaxing
Solution, the bottom of described dewaxing cylinder is tapered, and the least significant end of conical bottom is provided with sand draining port, is provided with valve at sand draining port, leakage
At sand mouth, connection connects sand cylinder.
Further, described sand draining port is threadeded between sand cylinder with connecing, sand draining port and connect and be provided with sealing between sand cylinder
System.
Further, described heater includes jet chimney, temperature detect switch (TDS) and temperature measuring equipment, described jet chimney cincture
Dewaxing drum outer wall is arranged, circulation high-temperature steam in jet chimney；Temperature measuring equipment measures the temperature of dewaxed solution and by temperature data
It is transferred to temperature detect switch (TDS)；Temperature detect switch (TDS) is arranged on jet chimney, and temperature switch is according to the dewaxed solution temperature data received
The air inflow of regulation jet chimney.
Beneficial effect: the bottom of the dewaxing cylinder of (1) this utility model hot-water dewaxing device is tapered, the least significant end of conical bottom
Being provided with sand draining port, be provided with valve at sand draining port, connect sand cylinder at sand draining port, the sand grains of deposition is gathered in and connects sand cylinder
In, it is difficult to be rolled up to formwork inner chamber by the solution of convection current, effectively prevents sand hole.(2) sand draining port of this utility model dewaxing cylinder
Threaded between sand cylinder with connecing, sand draining port and connect and be provided with sealing system between sand cylinder, connect the feelings that sand cylinder can be closed at valve
Being removed under condition, connect the sand grains in sand cylinder with emptying, this process need not the dewaxed solution in emptying dewaxing cylinder, it is not required that stops
Anti-avulsion wax works, and improves production efficiency.
Accompanying drawing explanation
Fig. 1 is this utility model hot-water dewaxing device structural representation.
Wherein: 1, dewaxing cylinder；11, sand draining port；2, valve；3, sand cylinder is connect；4, jet chimney；5, temperature detect switch (TDS)；6, thermometric

Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
As it is shown in figure 1, the hot-water dewaxing device of the present embodiment, including dewaxing cylinder 1, valve 2, connect sand cylinder 3, jet chimney 4,
Temperature detect switch (TDS) 5 and temperature measuring equipment 6.Containing dewaxed solution in dewaxing cylinder 1, the bottom of dewaxing cylinder 1 is tapered, the least significant end of conical bottom
It is provided with sand draining port 11, at sand draining port 11, is provided with valve 2, the threaded sand cylinder 3 that connects at sand draining port 11, sand draining port 11 and connect sand
It is provided with sealing system between cylinder 3.Jet chimney 4 is arranged around dewaxing cylinder 1 outer wall, circulation high-temperature steam in jet chimney 4；Survey
Temperature device 6 is measured the temperature of dewaxed solution and temperature data is transferred to temperature detect switch (TDS) 5；Temperature detect switch (TDS) 5 is arranged on jet chimney 4
On, temperature switch is according to the air inflow of the dewaxed solution temperature data regulation jet chimney 4 received.
The use step of the present embodiment hot-water dewaxing device is: (1) configuration quality percentage ratio be 5～7% ammonium chloride molten
Liquid is placed to dewaxing cylinder 1 as dewaxed solution；(2) being passed through high-temperature steam heating dewaxed solution in jet chimney 4, thermometric fills
Putting 6 measurement dewaxed solution temperature and be transferred to temperature detect switch (TDS) 5, when temperature reaches 85 DEG C, temperature detect switch (TDS) 5 reduces jet chimney 4
The air inflow of interior high-temperature steam, to reduce the programming rate of dewaxed solution gradually to thermal balance, keeping dewaxed solution temperature is 85
～between 95 DEG C；(3) in promoting basket 8, place wax-pattern 7, then lifting basket 8 and wax-pattern 7 are immersed in dewaxed solution, during immersion
Between with the wax in wax-pattern 7 all molten to the greatest extent till.
Hot-water dewaxing device, during constantly using, gradually has the sand grains deposition come off from wax-pattern 7 to dewaxing cylinder 1
Bottom, due to the setting of taper bottom surface, sand grains each falls within and connects in sand cylinder 3.Connect the area end much smaller than dewaxing cylinder 1 of sand cylinder 3
Face sectional area, even if dewaxed solution is internal, and slight convection current occurs, connects the sand grains in sand cylinder 3 and also will not (dewax to wax-pattern 7 by turnup
After become formwork) inner chamber.When hot-water dewaxing device normally uses, valve 2 should be at open mode, in order to sand grains falls into and connects
Sand cylinder 3.After hot-water dewaxing device works a period of time, connect the sand grains deposition in sand cylinder 3 more, now can close valve 2, take
Under connect sand cylinder 3 and clear up, reinstall after having cleared up and connect sand cylinder 3.
Although in description being illustrated embodiment of the present utility model, but these embodiments are intended only as carrying
Show, should not limit protection domain of the present utility model.Without departing from carrying out various omission in the range of this utility model objective, putting
Change and change should be included in protection domain of the present utility model.
