Abstract
The invention discloses a wet-pressing molding centralized vacuum drainage system, comprising double-vacuum pump groups, a vacuum tank, a moisture separator and a valve. The technical points of the system are as follows: the outlet ends of two groups of double-vacuum pumps arranged in parallel are communicated by a three-way valve, a negative pressure vacuum tank and the moisture separator in turn, and the outlet ends on the top part of the moisture separator is communicated with the inlet ends of at least two hydraulic press moulds arranged in parallel by an anti-corrosion pipeline and the valve; the vacuum degree in the system is maintained in a constant range; and the end part of a water drain pipe at the bottom part of the moisture separator is also provided with a flip-style drainage door with a rubber gasket. The vacuum drainage system reduces the work noise, power consumption and floor area of the pumps; the reciprocating vacuum pump groups are connected with a large vacuum tank through the three-way valve to keep the vacuum degree of the whole system stable, thereby improving the molding efficiency in pressing slugs; meanwhile, all pipelines adopt PC plastic pipes and the mode of embedding pipes underground, thereby reducing the amount of the maintenance of the pipelines.
Description
Technical field
The present invention relates to a kind of drainage vacuum system design field, specifically in the permanent-magnet ferrite wet therapy forming process, a kind ofly can improve the blank shaping efficiency, cut down the consumption of energy, the centralized low-pressure drainage system of Wet-pressing molding of noise and maintenance capacity.
Background technology
It is quite ripe that permanent-magnet ferrite develops so far technology, but produce the high-performance permanent-magnet ferrite product, still extensively generally adopts the moulding process in wet pressing magnetic field.In order to guarantee blank quality and production efficiency, in the Wet-pressing molding process, adopt low-pressure drainage system.And exhausted at present big many producers still adopt water-ring vacuum pump that every hydraulic press is vacuumized draining, and still this method existence vacuumizes shortcomings such as efficient is low, and floor space is big, and operating noise is big, and maintenance load is big, is unfavorable for modern production.
Summary of the invention
The purpose of this invention is to provide a kind of centralized low-pressure drainage system of Wet-pressing molding in permanent-magnet ferrite Wet-pressing molding process.
The object of the present invention is achieved like this: it includes compound vavuum pump group, vacuum tank, steam trap, valve, it is characterized in that: pass through three-way valve successively at two groups that are set up in parallel compound vacuum pump outlet ends, the negative-pressure vacuum jar, steam trap is connected, and is connected by anti-corrosion pipeline, valve and two hydraulic press die entrance ends being set up in parallel at least at the top exit end of steam trap; Vacuum in the described system remains on 3 * 10
4Pa～6 * 10
4In the Pa scope, connecting line and anti-corrosion pipeline all adopt nonmetal pipeline, also are provided with the convertible drainage door of a band rubber gasket in the drainpipe end of steam trap bottom.
Vacuum in the said system remains on 5 * 10
4Pa～6 * 10
4Be best in the Pa scope.
Described nonmetal pipeline is the PC plastic tube, and adopts the mode of underground buried tube, has both alleviated the maintenance capacity of pipeline, makes whole workshop seem neat and artistic again.
Two groups of compound vavuum pumps are alternate runs, that is to say when wherein one group normally moves, and another group is for standby.
Drainage system of the present invention can guarantee the vacuum in the drainpipe when moulding, and the vacuum in the drainpipe is maintained within a certain range all the time, has improved the shaping efficiency of blank in the wet method permanent-magnet ferrite technology greatly, has reduced energy consumption, noise and maintenance capacity.
The present invention vacuumizes owing to adopting the alternative water-ring vacuum pump in the past of reciprocating vacuum pump group to carry out system, has reduced pump work noise, power consumption and floor space; Reciprocating vacuum pump group place connects a large-scale vacuum jar by three-way valve, makes the vacustat of whole system remain on 5 * 10
4Pa～6 * 10
4Pa, the shaping efficiency when having improved slug press; All pipelines all adopt the PC plastic tube simultaneously, and adopt the mode of underground buried tube, have both alleviated the maintenance capacity of pipeline, make whole workshop seem neat and artistic again.The present invention also has simple in structure, and the whole system stable working state is easy to operate, is convenient to maintenance, characteristics such as long service life.

To be described in further detail invention by example below, but following example only is the present invention's example wherein, the rights protection scope of not representing the present invention and being limited, the scope of the present invention is as the criterion with claims.
The specific embodiment
By shown in Figure 1, among the figure 1,2 is two set reciprocating vavuum pumps in the centralized low-pressure drainage system of the present invention, 2 set reciprocating vavuum pumps wherein under the ordinary production state (and other 1 group standby when being maintenance of equipment, to guarantee continuous ordinary production), wherein every group of configurable vavuum pump is 1～5; Among the figure 4 is the negative-pressure vacuum jar, and the volume size is 2～10m
3Junction at each reciprocating vacuum pump and negative-pressure vacuum jar 4 is provided with a three-way valve 3, is used for the vacuum of regulating system; Simultaneously vacuum tank links to each other with 1～3 steam trap 6 again, melts PC plastic tube anti-corrosion pipeline, valve 7 by heat and hotly melts PC plastic tube underground piping and be connected on the mould of each hydraulic press 8 at the top exit end of steam trap 6.All pipelines all adopt the mode of underground buried tube, make that whole workshop is neat and artistic, vacuum pipe adopts heat to melt the PC plastic tube simultaneously, replace in the past metallic conduit in the traditional handicraft, thoroughly solved intimate property, and the easy hard nut to crack of blocking pipe, guaranteed pipeline unimpeded in continuity is produced because of metallic conduit and ferrite slurry, compare with traditional metal tube simultaneously, adopt heat to melt the service life that the PC plastic tube has also prolonged pipeline.In addition, 5 among the figure is vacuum meter.
When press breaks down, can close the shutoff valve of every press mold drainage position, make whole system still can remain on 5 * 10
4Pa～6 * 10
4Vacuum in the Pa scope; In whole vacuum system, have only a small amount of hydraulic press to be in normal operating conditions, can make the vacuum of whole system still can remain on 5 * 10 by regulating the three-way valve at reciprocating vacuum pump aspirating hole place
4Pa～6 * 10
4In the Pa scope.
Whole vacuum system adopts automatic drainage pattern simultaneously, promptly also is provided with the convertible water valve 11 of a band rubber gasket 10 in drainpipe 9 ends of steam trap bottom.After vavuum pump was shut down, the vacuum of steam-water separator descended, and the rubber gasket 10 at steam-water separator bottom discharge pipe place can be subjected to the effect of inside water pressure, automatically springs open with convertible water valve 11, carries out draining automatically; When vacuum system returned to normal vacuum range again, the vacuum of steam trap inside can be drawn onto convertible water valve 11 on drainpipe 9 end positions automatically, and adopts rubber gasket 10 that the drainpipe of steam-water separator is airtight simultaneously.
