Description
Technical field
The present invention relates to the built-in drying system of a kind of electronic analytical balance, belong to the electronic analytical balance technical field.
Background technology
Electronic analytical balance is a kind of precision of widespread use instrument of weighing, degree of accuracy generally at 0.001 gram to 0.0001 gram even higher.Many weighed objects all are through drying and dehydrating, cooling, are placed on then on the pallet in the balance and weigh; Because the air humidity and the atmospheric humidity around the balance of the confined space at balance inner pallet place are basic identical; Often cause the dry object of crossing constantly to absorb moisture when weighing; The quality numerical value that shows constantly increases, and the error of generation has directly had influence on the accuracy of experimental result.
Summary of the invention
To the blank of prior art, the present invention provides a kind of electronic analytical balance built-in drying system.
The built-in drying system of a kind of electronic analytical balance, native system comprise top cover, warehouse, drying agent Storage Box and locking switch; Top cover is square, and is located at the top or the side of balance, is positioned at the rear portion of the part of weighing; The hinge turning gear is formed with the balance housing in the forward one side of top cover; Top cover can rotate more than 90 degree around this rotating shaft, and top cover leans on below on one side, back that one lockhole is arranged, and adapts with the plug of locking switch; Warehouse is rectangular structure; Suitable for reading opening wide, the face between warehouse and the scales/electronic balance weighing part is provided with several pores, and its excess-three face and bottom surface are enclosed construction; Upper edge, warehouse top is provided with a quad seal circle; Be provided with two springs in the outside back side top of warehouse, when plug is extracted from lockhole, can be with top cover one end jack-up; The drying agent Storage Box is arranged in warehouse; Also be rectangular structure, when the warehouse top cover is opened, can it vertically put into warehouse and do not influence closing of top cover from top; The drying agent Storage Box is suitable for reading to open wide and is provided with a handle; Drying agent Storage Box one side forward is wire netting closely, and its excess-three face and bottom surface are enclosed construction, places solid drier in the drying agent Storage Box; Locking switch is arranged on balance bonnet top; The lockhole that its plug passes circular hole and the top cover below on bonnet, the stator adapts; When the draw ring of pulled backwards locking switch; Plug skids off from the lockhole of top cover, and top cover can be opened under the elastic force effect of two springs of the outside back side top of warehouse automatically.
In the use, the moisture in the drying agent sorption balance guarantees that balance weighs, analyzes accurately.After the drying agent moisture absorption in the drying agent drying agent Storage Box is saturated; The color of drying agent can change (for example: discolour silica gel can become pink by blueness); Can spur the draw ring of locking switch this moment, and top cover is upspring, and catches the handle on the drying agent Storage Box then; Taking-up drying agent Storage Box is directly put into baking oven dries, and after cooling, just can relay to get back in the warehouse to be repeatedly used.
Advantage of the present invention:
Air drying, the stability when having guaranteed to weigh and the accuracy of data that 1, can keep the space of weighing at balance inner pallet place.
2, the native system device does not take the space of weighing in the inside of balance, does not influence operation.
3, the picking and placeing and reusing of the design's convenient and dry agent, system's leakproofness is good.
4, instrument is under the dry environment for a long time, can guarantee its degree of accuracy, has prolonged the serviceable life of balance simultaneously.
