A kind of material adding set

Technical field

The utility model relates to the adding set of a kind of particulate matter and thick liquid, particularly utilizes material conveying mechanism and sensor to control the automatic interpolation of material.Belong to chemical laboratory automated material and add field.

Background technology

Weighing solid chemicals in front chemical laboratory adopts the manual application of sample of analytical balance to weigh mostly.As everyone knows, chemical reagent sample type is many, and sampling amount is few, and precision prescribed is high, and this work is dull, weighs efficiency manually low.

In part Experiment operation, the method for operation of saltouing that such as protein purification adopts, needs the chemical reagent adding specified quantitative according to certain speed, makes solution reach corresponding concentration of ions.Mostly adopt at biology laboratory at present and manually add, and manual operation is difficult to ensure conformability.

US7996107B2 discloses a kind of device of automatic weighing solid material.This device adopts the gear on motor driving sample bottle, and then drives the screw rod in bottle to rotate, thus extruded material, weigh.A drawback of this device is that the material in bottle is with sample bottle together rotary motion motor drives sample bottle to rotate while.When relating to a large amount of sample weighings, first need in bottle to store a large amount of material, along with the increase storing weight of material in bottle, body will acutely swing in rotation process.For stable sample bottle, need complicated fixing and transmission device, the complexity of this equipment not only increased and manufacture difficulty, increase cost, also limit the convenience of quick-replaceable sample bottle.

Summary of the invention

The purpose of this utility model is for solving the problems such as manual weighing's efficiency is low, error is large in chemical laboratory, provides a kind of structure simple, accurate material adding set automatically, has and preserve material, preventing pollution, quick-replaceable material, the simple advantage of structure.

To achieve these goals, the technical solution adopted in the utility model is as follows:

A kind of material adding set, comprise device for transporting objects, sensor and controller, device for transporting objects comprises sample bottle and driver train, described sample bottle comprises upper bottle cover, body, barrel, screw bracket, screw rod, lower bottle cap, described upper bottle cover and lower bottle cap lay respectively at the upper and lower side of body, and are fixedly connected with body.Described screw bracket is fixed in sample bottle, and described screw rod is fixedly connected with described screw bracket, and a screw rod part extends in barrel; Described lower bottle cap hollow, described barrel is concentric with lower bottle cap, through lower bottle cap, can rotate around screw rod; Described driver train can be fixed lower bottle cap and drive barrel to rotate; Described controller is connected with described sensor, device for transporting objects respectively.

Preferably, described driver train comprises motor, gear cluster, base, described motor is fixed on base, described gear cluster is positioned at described base, described motor is connected with described gear cluster, and described base also comprises a draw-in groove, and described draw-in groove is by fixing lower bottle cap and then fixing whole sample bottle, the outer wall of the endoporus and described barrel that are positioned at draw-in groove bottom cog in described gear cluster is interlocked, and barrel can be driven to rotate.

Preferably, there is signal to launch and receiving device in described controller, and be connected with device for transporting objects with sensor respectively.

Preferably, can set in described control system according to certain speed continuously or timing add materials.

Preferably, described sensor is the combination of appointing one or more in weight sensor, conductivity sensor, temperature sensor, pH sensor, pressure sensor.

When described sensor is conductivity sensor, temperature sensor, when pH sensor or pressure sensor, now in the container of sensor setting below device for transporting objects, measure the parameter in container, add mixing device if desired.

During use, material is loaded on sample bottle inside, and sample bottle is fixed on base by draw-in groove.Controller is according to the instruction of input, and the signal of combined sensor feedback, the motor controlled in device for transporting objects drives barrel to rotate, and then controls mass transport.

The beneficial effects of the utility model are, the utility model overcomes in classic screw conveying mechanism and usually adopts drive screw to rotate, the technology prejudice that barrel is static.The creationary mass transport mode that have employed driving barrel and rotate.For screw rod and the barrel of same structure, adopt the mode convey materials that barrel rotates, due to barrel smooth surface, relatively with material area of contact to reduce, efficiency will lower than the mode adopting screw rod to rotate.But this feature is particularly suitable for precision conveying and the metering of trace material, and for the screw rod of same structure, barrel, sensor and control system, the mode convey materials adopting barrel to rotate, can significantly improve delivery precision, reduces deviation.Meanwhile, for same accuracy requirement, the requirement degree to part processing precision and control system performance can be reduced.

Another one beneficial effect of the present utility model is, compare US7996107B2 and adopt the mode driving sample bottle and then drive screw, now in bottle, material rotates with body, material increase then rotor inertia increase in bottle, if material skewness weighing apparatus in bottle, violent shake will be caused, then need complicated transmission and fixed mechanism.The utility model adopts the mode driving barrel to rotate, even if material increases or uses bulk sample bottle instead in bottle, owing to being drive barrel to rotate, rotor inertia is substantially constant.The stability that in sample bottle, material increase causes can be avoided to reduce problem, the stability of conveying mechanism running can be strengthened, reduce the complexity of driver train.And then reduce interference, improve automatic weighing precision, reduce costs.

The object of tradition automatic weighing solution is generally a certain amount of material of weighing fast as far as possible.The utility model can set material that is continuous according to certain speed or timing interpolation specified quantitative in the controls.This function, for the experimental implementation of a class of saltouing, can improve performance accuracy and save manpower.

For class experimental implementation of saltouing, not only can control the chemical reagent adding specified weight by working weight sensor, can also adopt separately or in conjunction with conductivity sensor, directly measure effects of ion concentration, and then control salting-out process more accurately.
