Description
Technical field
It the utility model is related to detection device technology field, and in particular to the detection dress that a kind of crucible for crystal growth is leaked hunting
Put.
Background technology
With the development of society and the progress of industry, various aspects of the artificial lens in Modern High-Tech field are obtained for
It is widely applied.Many places can see the figure of crystal, such as two poles in various electronic products in our daily lifes
Manage, the luminescence medium in electric advertisement screen, piezoelectric ceramics in lighter.
Crucible is particularly important as essential consumptive material in artificial lens production process, and the quality of crucible quality directly affects
The success rate of the growth of crystal.Because artificial crystal growth environment is complicated, crystal growth temperature height and growth time, cause whole
Very high to the quality requirement of crucible in crystal growing process, the seepage or cracking of crucible, causing crystal growth, all that has been achieved is spoiled.By
This visible crucible as consumptive material in crystal growing process it is particularly significant.
The inspection of crucible is particularly significant, especially leaks hunting.At present, generally detected using kerosene seepage method, detection method ten
Divide simply, i.e., kerosene is poured into crucible and stand 30 minutes, such as do not find that no seepage is as qualified.But real crystal produces
In, crucible is operated in temperature and is up to and is worked in the range of 1600~2100 DEG C (different crystal growth temperatures is different), during work
Grow at 150~250 hours.The quality of crucible of being worked under such high temperature and long-time is even more important.And current method is only
It is to stand 30 minutes at normal temperatures, it is clear that be difficult to meet actual requirement, crucible leakage will cause unnecessary production to waste.
Utility model content
The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided a kind of simple in construction, design is closed
The detection means that reason, crucible for crystal growth easy to use are leaked hunting, simple to operation, effect of leaking hunting is good, greatly improves crucible
Quality, practicality are stronger.
To achieve the above object, the technical solution adopted in the utility model is：It include bottom rubber blanket, stool,
Fastening bolt, standing screw, top rubber pad, mouth of pot pressing plate, air inlet, pressure gauge connection；Crucible is arranged on stool
Between mouth of pot pressing plate, bottom rubber blanket, crucible upper opening and mouth of pot are provided between the bottom of crucible and stool
Top rubber pad is provided between pressing plate；Pass through several standing screws and fastening spiral shell between described stool and mouth of pot pressing plate
Bolt is connected, and several standing screws are evenly distributed on the perisporium of mouth of pot pressing plate；Offered in described mouth of pot pressing plate into
Gas port and pressure gauge connection；The bottom external diameter of described crucible is more than the opening inside diameter in the middle part of stool.
Further, spring shim is provided between described fastening bolt and stool.
Further, described bottom rubber blanket is in flat shape or arcuate bottom shape.
After said structure, the utility model has the beneficial effect that：Crucible for crystal growth described in the utility model is surveyed
The detection means of leakage, simple to operation, effect of leaking hunting is good, greatly improves crucible quality, and practicality is stronger, and the utility model has
Simple in construction, it is reasonable to set, the advantages that low manufacture cost.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Description of reference numerals：
Crucible 1, bottom rubber blanket 2, stool 3, fastening bolt 4, standing screw 5, spring shim 6, top rubber pad
7th, mouth of pot pressing plate 8, air inlet 9, pressure gauge connection 10.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Referring to as shown in figure 1, the technical scheme that present embodiment uses is：It includes bottom rubber blanket 2, crucible bottom
Seat 3, fastening bolt 4, standing screw 5, top rubber pad 7, mouth of pot pressing plate 8, air inlet 9, pressure gauge connection 10；Crucible 1 is set
To put between stool 3 and mouth of pot pressing plate 8, the bottom of crucible 1 is provided with bottom rubber blanket 2 with the contact position of stool 3,
Prevent the lower surface of crucible 1 that by the gouge of stool 3, top rubber is provided between the upper opening of crucible 1 and mouth of pot pressing plate 8
Pad 7, play a part of isolating and seal；Between described stool 3 and mouth of pot pressing plate 8 by several standing screws 5 and
Fastening bolt 4 is connected, and several standing screws 5 are evenly distributed on the perisporium of mouth of pot pressing plate 8；Described mouth of pot pressing plate 8
Inside offer air inlet 9 and pressure gauge connection 10；The bottom external diameter of described crucible 1 is more than in the opening at the middle part of stool 3
Footpath.
Further, spring shim 6 is provided between described fastening bolt 4 and stool 3.
Further, described bottom rubber blanket 2 is in flat shape or arcuate bottom shape.
The operation principle of present embodiment：Before being detected, respectively by air inlet 9 and pressure gauge connection 10 with
Air pressure experimental machine and pressure gauge connect, and place into water, it is ensured that detection means is under liquid level, by air pressure testing machine by gas
Squeeze into inside crucible 1, when instrument shows pressure position 1MPa, keep the pressure to check whether instrument has pressure release after 30 minutes
Sign, if during without pressure release sign, illustrating the reliable welding quality of crucible 1, welding defect；Otherwise, there is leakage point, can be by water
The bubble of effusion judges defective locations；The device has two advantages relative to kerosene detection：First, gas accuracy of detection is remote high
In kerosene seepage；2nd, detect under stress, crucible defect is more easy to be found.
After said structure, present embodiment has the beneficial effect that：Crystal growth described in present embodiment
The detection means leaked hunting with crucible, simple to operation, effect of leaking hunting is good, greatly improves crucible quality, practicality is stronger, this practicality
New have simple in construction, and it is reasonable to set, the advantages that low manufacture cost.
It is described above, only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple
The other modifications or equivalent substitution that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, it all should cover among right of the present utility model.
