Abstract
The utility model discloses a negative-pressure sand remover which comprises an air inlet pipe, a negative-pressure sand suction pipe and an air outlet pipe, wherein the air inlet pipe is connected with the air outlet pipe; the negative-pressure sand suction pipe is arranged at the rear end of the air outlet pipe; the included angle between the air inlet pipe and the negative-pressure sand suction pipe is an acute angle of 30-60 degrees; the negative-pressure sand suction pipe is a sharp nozzle. According to the sand remover, fallen sand of a casting box body can be effectively removed to improve the product quality.
Description
Technical field
The utility model relates to a kind of sand-removal device of foundry industry, relates in particular to a kind of negative pressure desander.
Background technology
Massive casting casing is at the trial-production initial stage, there is knockout on casing top at every turn, knockout is few, tiny, but affect product quality, by analysis, fine sand is because casing is too large, and we can not blow clean knockout with hair-dryer, and special place, some position blow at all less than, and these fine sands are in casting process, will float to from bottom top, and be collected at again higher place, a certain position, this just forms knockout on the top of casting box, if can be with a flexible pipe, extend into special position spun yarn sucking-off, just can address this problem.
Summary of the invention
The purpose of this utility model is to provide a kind of negative pressure desander, can effectively remove doffing of casting box, improves the quality of products.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of negative pressure desander, it is characterized in that: negative pressure dust removing device inhales sand tube by air inlet pipe, negative pressure and escape pipe forms, and air inlet pipe connects escape pipe, and the rear end of escape pipe is that negative pressure is inhaled sand tube part, angle between air inlet pipe and negative pressure suction sand tube is the acute angle of 30 °-60 °, and it is sharp mouth that negative pressure is inhaled sand tube.
According to described negative pressure desander, it is characterized in that: the negative pressure of described negative pressure dust removing device is inhaled sand tube and is inserted in die cavity, and the outside of die cavity is husky mould, and the inner side of die cavity is provided with fuse.
The utility model has the advantages of and be: 1, removing the knockout in casting mold cavity with hair-dryer, clear up not thoroughly, is often that calm detectable place has blown to corner, and negative pressure desander to be location remove, as long as discovery knockout just can directly siphon away.2, the degree of depth of casting mold cavity is darker, more difficult with the clear knockout of hair-dryer, and negative sand desander does not just have this problem.3, negative sand desander adapts to can't see in corner especially local desanding, particularly hole, stitch tiny position.4, negative pressure desander use simple especially, casting unit have air compressor machine, air blast is just from air compressor machine.The control of switch is also simple especially, in use, if temporarily need not, just the doubling of air intake flexible pipe, with holding tight just pass in the dust, unclamp and just can continue to use.5, in modeling process, if find that there is knockout after good and sound fuse mould assembling, if the clear knockout of hair-dryer just can only open case and take off fuse removing, and negative sand desander is as long as go deep into knockout place pipe, sucking-off.
Accompanying drawing explanation
Fig. 1 is use schematic diagram of the present utility model.
Fig. 2 is the structural representation of negative pressure dust removing device in Fig. 1.
In accompanying drawing: 1, fuse; 2, die cavity; 3, negative pressure dust removing device; 4, air inlet pipe; 5, negative pressure is inhaled sand tube; 6, escape pipe.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The utility model is as shown in Fig. 1 or 2, a kind of negative pressure desander, it is characterized in that: negative pressure dust removing device 3 inhales sand tube 5 by air inlet pipe 4, negative pressure and escape pipe 6 forms, air inlet pipe 4 connects escape pipe 6, the rear end of escape pipe 6 is that negative pressure is inhaled sand tube 5 parts, angle between air inlet pipe 4 and negative pressure suction sand tube 5 is the acute angle of 30 °-60 °, and it is sharp mouth that negative pressure is inhaled sand tube 5.According to described negative pressure desander, it is characterized in that: the negative pressure of described negative pressure dust removing device 3 is inhaled sand tube 5 and is inserted in die cavity 2, and the outside of die cavity 2 is husky mould, and the inner side of die cavity 2 is provided with fuse 1.
Use principle of the present utility model as shown in Figure 1, 2, gas is entered from air inlet pipe 4, from escape pipe 6 out, the gas that negative pressure is inhaled in sand tube 5 under the effect of air-flow like this can flow to escape pipe 6 under the effect of air-flow, thereby the afterbody point mouth that makes negative pressure inhale sand tube 5 has a suction, can absorb the fine sand of die cavity 2.Removing the knockout in casting mold cavity with hair-dryer, clear up not thoroughly, is often that calm detectable place has blown to corner, and negative pressure desander to be location remove, as long as discovery knockout just can directly siphon away.The degree of depth of casting mold cavity is darker, more difficult with the clear knockout of hair-dryer, and negative sand desander does not just have this problem.Local desanding, particularly hole that negative sand desander adapts to can't see in corner especially, stitch tiny position.Negative pressure desander uses simple especially, and there is air compressor machine in casting unit, and air blast is just from air compressor machine.The control of switch is also simple especially, in use, if temporarily need not, just the doubling of air intake flexible pipe, with holding tight just pass in the dust, unclamp and just can continue to use.In modeling process, if find that there is knockout after good and sound fuse mould assembling, if the clear knockout of hair-dryer just can only open case and take off fuse removing, and negative sand desander is as long as go deep into knockout place pipe, sucking-off.
Embodiment recited above is described preferred embodiment of the present utility model; not design of the present utility model and protection domain are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model, all should fall into protection domain of the present utility model.
