Description
Technical field
The present invention relates to a kind of flusher of casting water dissolved salt core, belong to salt core aluminium recovery casting technology field.
Background technology
Because aluminium recovery is operationally subject to larger mechanical load and thermic load for a long time, for preventing aluminium recovery top from cracking, its temperature can not more than 350 DEG C ~ 375 DEG C; In addition, for keeping lubrication good, prevent carbon deposit, do not make annular groove rapid wearing, first annular groove temperature should control at 200 DEG C ~ less than 220 DEG C; For this reason, needing first or first and second annular groove place, road castingin austenitic cast iron abrasion-proof inserted ring at aluminium recovery, at piston top by processing interior oil cooling passage with water-soluble salt core near edge circle, again the water-soluble salt core of filling in oil cooling passage in aluminium recovery being rinsed removing after shaping.In the prior art, rinse shaping after aluminium recovery in the method for water-soluble salt core in oil cooling passage is normally direct running water is connected on oil hole rinses, there is activity duration long, water-soluble salt core and wash away the defects such as not thorough, the residual water dissolved salt core adhered to has very large corrosiveness to piston, and can not form smooth interior oil cooling passage.
Summary of the invention
The present invention for the deficiency that prior art exists, provides a kind of flusher of casting water dissolved salt core, can improve the flushing operating efficiency of water-soluble salt core, and reduce the residual rate of water-soluble salt core in interior oil cooling passage, meet actual operation requirements just.
For solving the problem, the technical solution used in the present invention is as follows:
A flusher for casting water dissolved salt core, comprising:
Rinse water source and circulating water pool for reclaiming flushing water for providing, be provided with flushing sparge pipe above described circulating water pool, 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 of described pneumatics pump is communicated with air, and 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 described flushing sparge pipe and the junction of described outlet pipe and described flushing sparge pipe is provided with curved transition sections; The water inlet end of described curved transition sections and described outlet pipe are in the same way, the water side of described curved transition sections towards described flushing sparge pipe current downstream and with described flushing sparge pipe in the same way, in the same way, 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 comprise the drive motors for providing Power output to described pressure pump and described pneumatics pump, and described pressure pump and described pneumatics pump share a described drive motors.
Compared with prior art, implementation result of the present invention is as follows in 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 be mixed into has brought again a large amount of turbulent flow into, add breaking of a large amount of bubble, these all accelerate the scour process of salt core, salt core effectively can be rinsed well under the current of high pressure, can improve the flushing operating efficiency of water-soluble salt core, and reduce the residual rate of water-soluble salt core 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
Below in conjunction with specific embodiments content of the present invention is described.
As 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, comprise: rinse water source and circulating water pool 1 for reclaiming flushing water for providing, be provided with above described circulating water pool 1 and rinse sparge pipe 2, 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 of described pneumatics pump 7 is communicated with air, and the outlet side of described pneumatics pump 7 connects the current upstream extremity of described flushing sparge pipe 2.
Particularly, described outlet pipe 6 is perpendicular to described flushing sparge pipe 2 and described outlet pipe 6 is provided with curved transition sections 8 with the junction of described flushing sparge pipe 2; The water inlet end of described curved transition sections 8 and described outlet pipe 6 are in the same way, the water side of described curved transition sections 8 towards described flushing sparge pipe 2 current downstream and with described flushing sparge pipe 2 in the same way, in the same way, 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.Further preferably, also comprise the drive motors 9 for providing Power output to described pressure pump 4 and described pneumatics pump 7, and described pressure pump 4 and described pneumatics pump 7 share a described drive motors 9.Described pressure pump 4 and described pneumatics pump 7 share the overall manufacturing cost and use cost that a described drive motors 9 can reduce equipment.
