Description
Technical Field
The utility model relates to a device is got to powdered medicine ration title of solid state that laboratory was used belongs to and detects technical field.
Background
At present, liquid reagents (such as methanol, acetonitrile and the like) used in laboratories can be quickly and accurately measured through a bottle mouth separator. Solid powdered drugs are usually weighed accurately by using a balance, and a detector usually takes more or less drugs and continuously adjusts the drugs, thereby wasting time and labor. The laboratory for food detection has large test sample amount, dozens or even hundreds of parallel tests are usually carried out in each test, and the stability and result reproducibility of an analysis test are influenced due to different solid powder medicine sample amounts. Therefore, a device is urgently needed for quantitatively dispensing solid powdery medicines so as to improve the accuracy of the weighing amount, reduce the manual demand and improve the test efficiency; the problem of poor analysis result reproducibility caused by poor parallelism of medicine quantity weighed one by using an electronic scale is also solved, and the detection requirements of a large number of samples can be met.
Disclosure of Invention
An object of the utility model is to provide a device is got to powdered medicine ration title in solid state that laboratory was used, this equipment have accurate, quick, convenient branch get solid-state powder's function.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model discloses a device is got to manual title of solid-state powdered medicine, the device includes frame 1, defeated material module, weighing module, waste recovery box 8. A material conveying module is arranged at the upper part of the frame 1; the material conveying module consists of a storage bin 2, a spiral material conveyor 3 and a rocking handle 4. A weighing module is arranged right below the outlet of the spiral feeder 3; the weighing module consists of a precision electronic scale weighing device 5 and a material taking funnel 6; the material taking funnel 6 is connected with the precision electronic scale weighing device 5; the precise electronic scale weigher 5 is used for measuring the weight of the powdery medicine in the material taking funnel 6 and displaying the weight in a display screen of the precise electronic scale weigher; the regulating valve 7 is installed to 6 lower parts of the material taking funnel, and redundant solid powdered medicines can be released. A waste recovery box 8 is arranged at the bottom of the rack 1 and is positioned under the material taking funnel 6; the waste recovery box 8 recovers the powder medicine released excessively by the regulating valve 7.
The beneficial effect produced through the technical scheme is as follows: (1) by utilizing the linear relation between the material quantity and the revolution, the handle is rotated to drive the spiral material conveyer to convey the medicine, the precision electronic scale weighing device stops rotating when displaying that the weighing quantity reaches a required value, and the regulating valve 7 is used for taking the medicine. If the weighing value is different from the actual required value, the redundant solid powder medicine is released to the waste recovery box 8 through the regulating valve 7. When the weighing capacity reaches the required value, the regulating valve 7 takes materials. (2) The method is simple and easy to implement compared with the method of using a precision balance for weighing, and is more accurate compared with the method of using the balance for estimating the weighing by experience. And (3) the whole system is placed on a table top, and the rotation speed and the number of turns of the handle are controlled by rotation, so that the sampling amount is controlled. (4) Compared with the method that the precision balance is used by inspectors for weighing, the weighing speed is improved, and the working efficiency is greatly improved.
The utility model discloses simple structure, it is simple accurate convenient to divide and get solid powder medicine, easily preparation popularization.
Drawings
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Reference numbers in the figures: 1-frame, 2-storage bin, 3-spiral conveyer, 4-rocking handle, 5-precision electronic scale weighing device, 6-material taking funnel, 7-regulating valve, 8-waste recovery box.
Detailed Description
The precision electronic scale weigher 5 is zeroed according to the assembled apparatus shown in fig. 1.
Solid powder medicine to be weighed is put into the storage bin 2, and the rocking handle 4 is rotated to drive the spiral feeder 3 to convey the medicine out. After the medicine leaks into the material taking funnel 6, the numerical value of the precision electronic scale weighing device 5 is increased, and the rocking handle 4 is slowly rotated; when the precision electronic scale weigher 5 displays that the numerical value reaches the required weight, the rocking handle 4 stops rotating.
If the weight of the medicine in the material taking funnel 6 exceeds the required weight, the knob of the adjusting valve 7 is rotated, and the redundant powder medicine is leaked into the waste material recovery box 8. When the display screen of the precision electronic scale weigher 5 displays that the numerical value reaches the required weight value, the regulating valve 7 is rotated, and the centrifugal tube at the bottom of the regulating valve receives the quantitative powdery medicine.
Examples
The QuEChERS pretreatment method is generally used in laboratories due to the characteristics of rapidness, simplicity and the like. However, the laboratory generally purchases the dispersed solid phase extractants anhydrous MgSO4, PSA, C18, GCB, etc. The solid powder is generally 100-300 mesh with a particle size of 48-150 μm. For the accuracy of the experiment, one or more of the purification steps will be quantitatively weighed for the pretreatment process. At present, each powder is accurately weighed by a balance for a laboratory, which wastes time and labor; when the sample is taken by feel without using a balance, more or less samples are often taken, and different purification degrees can be caused by different sampling amounts of solid powder, so that the test stability is poor, and the result reproducibility is influenced.
When the hand-held automatic quantitative dispensing system for solid powder medicine is adopted,now add the material into 1
The precision electronic scale weigher 5 is zeroed according to the assembled apparatus shown in fig. 1.
Putting the solid powder medicine to be weighed intoStorage bin2, the rocking handle 4 is rotated to drive the spiral feeder 3 to convey the medicine out.
After the medicine leaks to the material taking funnel 6, the numerical value of the precision electronic scale weighing device 5 is increased, and the rocking handle 4 is slowly rotated; when the precision electronic scale weigher 5 displays that the numerical value reaches the required weight, the rocking handle 4 stops rotating.
If the weight of the medicine in the material taking funnel 6 exceeds the required weight, the knob of the adjusting valve 7 is rotated, and the redundant medicine is leaked into the waste recovery box 8. When the display screen of the precision electronic scale weigher 5 displays that the numerical value reaches the required weight value, the regulating valve 7 is rotated, and the centrifugal tube at the bottom of the regulating valve receives the quantitative powdery medicine.
