Description
Technical field
The utility model relates to a kind of arranging device of micro-electronic balance.
Technical background
Usually the arranging device of the balance that adopts has dual mode as shown in Figure 1.Among Fig. 1 shown in the 1-1 the sky platform with solid cement estrade as base, from bottom to top spread successively above the base one deck sheet rubber, one deck cork sheet and one deck by marble slab (or glass) make the sky platform table top, the size of table top is decided with the size of balance, and is general bigger slightly than the base of balance self.Platform must be placed on ground floor in this day, made troubles for conventional analytical work.The base of the sky platform among Fig. 1 shown in the 1-2 is a solid cement desk that cuts out a hole, load sand in the hole earlier, from bottom to top spread cork sheet (or sheet rubber) and glass table top again, the size of glass table top is decided by the base size of balance self, and balance is placed on this glass table top.The balance of placing on the platform in this day needs adjusting level continually.Sky platform shown in Fig. 1 generally is fixed on the floor of room corner.
Facts have proved, the arranging device and the mode of the accuracy of weighing result and reliability and balance are closely connected, the physical change of sample nature itself, as evaporation slowly, moisture absorption or magnetic force, electrostatic interaction and make sample and pan of a steelyard stressed etc., all reaction is the variation of quality on balance, and these influences are especially remarkable for ultramicron and micro-electronic balance.In the inventor's laboratory, once used sky platform shown in Figure 1 to place ultramicron and micro-electronic balance, but result of use is all undesirable.The sky platform of continuing to use in history keep away the requirement that the effect of shaking is difficult to reach micro-electronic balance operate as normal, need the design of day platform to reduce the influence of surrounding environment as much as possible to balance itself, so, need a kind of reliable and stable balance arranging device in actual use.
Summary of the invention
The utility model purpose is exactly in order to overcome the problem of above-mentioned existing day platform, a kind of arranging device of micro-electronic balance to be provided.
The utility model formation comprises a day platform, weighing operator's console and anti-air bell.Platform adopted bearing to be fixed on load-bearing pillar or the bearing wall in described day, and from 1～20 centimetre on wall; Described weighing operator's console is one to be cut out at place on one side and to remove wide each big 1～3 centimetre common table top than balance director, and be equipped with the sky platform, from 1～20 centimetre of installation of wall; Described anti-air bell can be made by transparent material, as glass, and is fixed on the weighing operator's console, and the limit of the bottom of the face of back is 1～2 centimetre with the spacing of day platform, and the oriented manipulation person's of anti-air bell a opening is convenient to operation.
The utility model is the arranging device of the micro-electronic balance of the anti-humiture influence of the anti-air-flow of vibrationproof effectively, and vibration-isolating effect is good, and is not subjected to the restriction of floor.

Embodiment
To help to understand the utility model by following embodiment, but not limit content of the present utility model.The key of day platform design is that the operator's console of using during with sky platform and weighing is separated among the embodiment, makes these two parts unaffected mutually.In the past, weighing was all done in the drilling of sky platform, and this makes the stability of balance be subjected to influence.Day platform in scheme of the present utility model (size is by the size decision of balance) is horizontally fixed on load-bearing pillar or the bearing wall with a secondary trivet, 1 centimetre away from wall more than, common 1～20 centimetre, recommend 2～10 centimetres be, between table top and bearing, can be encased inside stereotype and cork, as shown in Figure 2.
The weighing operator's console is one to be cut out at place on one side and to remove wide each big 1～3 centimetre common table top (Fig. 3) than balance director, and the whole operation table top must recommend 2～10 centimetres, and level height can be equal to or slightly lower than a day platform from 1～20 centimetre on wall.The support section of operator's console can adopt heavier material, also can be fixed on after the position is adjusted in installation on the floor, avoids being moved easily, sees Fig. 3.
The balance dedicated is that sky platform and weighing operator's console relative position are as shown in Figure 4 fixed, but without any direct coupling part.But tetragonal table top of the common composition of the table top of it platform and weighing operator's console.
On worktable, comprise common the composition on the tetragonal table top of table top of day platform and weighing operator's console, load onto independently anti-air bell for balance, avoid the interference aspect temperature and air-flow mutually, as shown in Figure 5.Anti-air bell can be made by transparent material, as glass, and is fixed on the weighing operator's console, and the limit of the bottom of the face of back is 1～2 centimetre with the spacing of day platform.The oriented manipulation person's of anti-air bell a opening is to make things convenient for the weighing operation.
In order to reduce the influence of air-flow to balance, can only there be a gateway in the laboratory of placing balance to prevent the influence of cross-ventilation to balance.Avoid the device of air-conditioning or band fan directly to face toward the position that balance is laid, to prevent the influence of strong air flow to balance.Two sects preferably are equipped with in the balance laboratory, little surge chamber of design between two sects, and the slidingtype sliding door is adopted at second sect, in the time of can avoiding personnel to pass in and out the balance laboratory like this, because the air-flow that the open and close of door cause changes.The spacing of two balances is at least 60 centimetres, in order to avoid interfere with each other.Be preferably on the worktable and load onto independently anti-air bell, avoid the interference aspect temperature and air-flow mutually, as shown in Figure 5 for every balance.Anti-air bell is made by clear glass, is fixed on the weighing operator's console, and the limit of the bottom of the face of back is 2 centimetres with the spacing of day platform.An opening of anti-air bell to be making things convenient for the weighing operation, and door (according to use experience, the switch of door can bring extra flow perturbation, the effect of anti-air bell that door is housed effective not as good as anti-air bell shown in Figure 5) is installed.If many balances are arranged in the balance laboratory, the balance worktable can be coupled together.
3. control temperature, humidity are to the influence of balance
The temperature of operating room, humidity control are very important.Can install an air-conditioner is controlled at operating room's temperature about 25 ℃, and should keep the stable influence to balance to prevent that temperature drift from causing as far as possible, also should avoid weighing near radiation source.When throw light in the installment work chamber, also should consider the position of light source, should be far away slightly apart from balance, the heat effects reading that light source is produced.
The relative air humidity of operating room should be controlled at (thereby suggestion is revised variation where necessary to the monitoring that micro-analytical balance continues) between 45% and 60%.Too dry as the operating room, can make static on the alleged heavy articles band, cause weighing error, can in the operating room, place basin, with suitable raising humidity; Divide too much as water in air, can make some the material moisture absorptions on the balance, also can cause weighing error, can be by regulating the room temperature or settling a dehumidifier to reduce humidity.
4. need diamagnetism and antistatic protection device in case of necessity
The influence of static makes the repeated very poor of weighing results on magnetic and the sample.Usually sample is placed in the container of permeability alloys system and takes by weighing, can screen out the influence of magnetic force like this.In of the influence of the other static of settling a wires ground connection to can be used for eliminating to exist between container, sample and sample spoon of balance, be a very simple and practical method to weighing.
