Description
Technical field
The present invention relates to the flusher of a kind of casting water dissolved salt core, belong to salt core aluminium recovery casting technology field.
Background technology
Due to aluminium recovery for a long time by bigger mechanical load and thermic load, for preventing aluminium recovery top from cracking, its temperature not can exceed that 350 DEG C～375 DEG C；It addition, for keeping lubrication good, prevent carbon deposit, do not make annular groove wear and tear rapidly, first annular groove temperature should control at 200 DEG C～less than 220 DEG C；For this reason, it may be necessary at the first or first and second castingin austenitic cast iron abrasion-proof inserted ring at road annular groove of aluminium recovery, piston top by insert near process interior oil cooling passage with water-soluble salt core, the water-soluble salt core will filled in oil cooling passage in aluminium recovery the most again rinses and removes.In the prior art, the method of the water-soluble salt core rinsed in the aluminium recovery after molding in oil cooling passage is typically directly tap water to be connected on oil hole and is rinsed, there is activity duration length, water-soluble salt core washes away the defects such as the most thorough, the residual water dissolved salt core adhered to has the biggest corrosiveness to piston, and can not form smooth interior oil cooling passage.
Summary of the invention
The deficiency that the present invention exists for prior art just, it is provided that the flusher of a kind of casting water dissolved salt core, it is possible to increase the flushing working performance of water-soluble salt core, and reduce water-soluble salt core residual rate in interior oil cooling passage, meet actual operation requirements.
For solving the problems referred to above, the technical solution used in the present invention is as follows:
A kind of flusher of casting water dissolved salt core, including:
For providing flushing water source and for reclaiming the circulating water pool of flushing water, described circulating water pool is provided above rinsing sparge pipe, and the current downstream of described flushing sparge pipe is provided with several Flushing nozzles；
For the pressure pump at pressure flush water source, the water inlet end of described pressure pump connects described circulating water pool by water inlet pipe, and the water side of described pressure pump connects described flushing sparge pipe by outlet pipe；
For providing compressed-air actuated pneumatics pump, the inlet end connection air of described pneumatics pump, the outlet side of described pneumatics pump connects the current upstream extremity of described flushing sparge pipe.
As the improvement of technique scheme, described outlet pipe is perpendicular to the junction of described flushing sparge pipe and described outlet pipe and described flushing sparge pipe and is provided with curved transition sections；The water inlet end of described curved transition sections is with described outlet pipe in the same direction, the water side of described curved transition sections is towards the current downstream and with described flushing sparge pipe in the same direction of described flushing sparge pipe, in the same direction, and described curved transition sections is between described pneumatics pump and described Flushing nozzle for the discharge directions of described pneumatics pump and described flushing sparge pipe.
As the improvement of technique scheme, also include the driving motor for providing power output to described pressure pump and described pneumatics pump, and described pressure pump and described pneumatics pump share a described driving motor.
Compared with prior art, the implementation result of the present invention is as follows for the present invention:
The flusher of a kind of casting water dissolved salt core of the present invention, compressed air is utilized to increase speed and the pressure of jet, the compressed air being mixed into has brought again a large amount of turbulent flow into, add rupturing of a large amount of bubble, these all accelerate the scour process of salt core so that salt core can be rinsed well under the current of high pressure effectively, it is possible to increase the flushing working performance of water-soluble salt core, and reduce water-soluble salt core residual rate in interior oil cooling passage, meet actual operation requirements.
Accompanying drawing explanation
Fig. 1 is the flusher structural representation of a kind of casting water dissolved salt core of the present invention.
Detailed description of the invention
Present disclosure is described below in conjunction with specific embodiments.
As it is shown in figure 1, be the flusher structural representation of a kind of casting water dissolved salt core of the present invention.The flusher of a kind of casting water dissolved salt core of the present invention, including: for providing flushing water source and for reclaiming the circulating water pool 1 of flushing water, described circulating water pool 1 is provided above rinsing sparge pipe 2, and the current downstream of described flushing sparge pipe 2 is provided with several Flushing nozzles 3；For the pressure pump 4 at pressure flush water source, the water inlet end of described pressure pump 4 connects described circulating water pool 1 by water inlet pipe 5, and the water side of described pressure pump 4 connects described flushing sparge pipe 2 by outlet pipe 6；For providing compressed-air actuated pneumatics pump 7, the inlet end connection air of described pneumatics pump 7, the outlet side of described pneumatics pump 7 connects the current upstream extremity of described flushing sparge pipe 2.
Specifically, described outlet pipe 6 is perpendicular to the junction of described flushing sparge pipe 2 and described outlet pipe 6 and described flushing sparge pipe 2 and is provided with curved transition sections 8；The water inlet end of described curved transition sections 8 is with described outlet pipe 6 in the same direction, the water side of described curved transition sections 8 is towards the current downstream and with described flushing sparge pipe 2 in the same direction of described flushing sparge pipe 2, in the same direction, and described curved transition sections 8 is between described pneumatics pump 7 and described Flushing nozzle 3 for the discharge directions of described pneumatics pump 7 and described flushing sparge pipe 2.It is further preferred that also include the driving motor 9 for providing power to export to described pressure pump 4 and described pneumatics pump 7, and described pressure pump 4 and described pneumatics pump 7 share a described driving motor 9.Described pressure pump 4 and described pneumatics pump 7 share a described driving motor 9 can reduce the overall manufacturing cost and use cost of equipment.
nullDescribed circulating water pool 1 is delivered to described flushing sparge pipe 2 by described pressure pump 4，And by described Flushing nozzle 3, the water-soluble salt core in oil cooling passage in the aluminium recovery after molding is rinsed operation，Described pneumatics pump 7 one aspect can increase the kinetic energy rinsing water source，Improve the washing pressure rinsing water source，And reduce the operation consumption of described pressure pump 4，On the other hand make described flushing sparge pipe 2 can be mixed into compressed air，Thus bring a large amount of turbulent flow into，During the water-soluble salt core in oil cooling passage, rupturing of a large amount of bubble can occur in aluminium recovery after rinsing molding，Thus accelerate the scour process of water-soluble salt core，Water-soluble salt core can be rinsed well under the current of high pressure effectively，In aluminium recovery after flushing molding, the operation of the water-soluble salt core in oil cooling passage was time-consumingly shortened to present ten minute by original 40 minutes，And developing result is reliable，Noresidue water-soluble salt core.
Above content is detailed description the most made for the present invention, it is impossible to assert that the present invention is embodied as being only limitted to these explanations.For those skilled in the art, without departing from the inventive concept of the premise, it is also possible to make some simple deduction or replace, all should be considered as belonging to the scope of protection of the invention.
