Abstract
The utility model discloses an automatic water changing device for a drug detector. The system structure of the automatic water changing device is as follows: a three-way valve is arranged at the middle of a pipeline between a water bath and a flask; the other path of the three-way valve is divided into the following two pipelines through a short pipe and a tee joint: one pipeline is connected with a filter and a water draining diaphragm pump in sequence, and an outlet of the pipeline is connected with a wastewater bucket; and the other pipeline is connected with a preheater and a water adding diaphragm pump in sequence, the tail end of the pipeline is provided with a filtering head, and the filtering head is placed in a pure water bucket. Only two water buckets are needed in the device, and the water can be changed through conversion of the valve after each experiment is finished. The automatic water changing device for the drug detector, disclosed by the utility model, has the advantages of simple structure and convenience for washing, meets national pharmacopoeia standards and can effectively reduce labor intensities of experiment operators. As the three-way valve is arranged as an electromagnetic valve and water draining and water adding buttons are arranged on an instrument operation board, a purpose of automatically changing water can be achieved.
Description
Technical field
The utility model belongs to the medicine detecting instrument, is specifically related to a kind of automatic water changer for the medicine detector.
Background technology
All be furnished with water-bath at present in drug test instrument (generally being called for short the medicine inspection instrument), and the experimental water amount is larger in the drug test process, and it is also larger to change the water frequency.Artificial changing water is all adopted in existing heating water bath class experiment, so cause experimenter's running program very numerous and diverse, especially tests in fast inspection car, and environmental baseline can't be carried out artificial changing water.Therefore bring the problems such as experimental period is long, labor intensity of operating staff is large.In order to improve the defective that existing medicine inspection instrument can not automatic water-replacing, the utility model provides a kind of automatic water changer, can realize facilitating automatic water-replacing in experimentation, when saving manpower, has shortened the experimental period interval.
Summary of the invention
The purpose of this utility model is that the automatic water changer in a kind of medicine detector and heating water bath quasi-instrument is provided.
The technical scheme that automatic water changer in the medicine detector is taked is: device comprises: water bath, beaker, T-valve, filtrator, the membrane pump that discharges water, wastewater barrel, pre-hot heater, add water membrane pump, filtering head and water-purifying tank etc.Be provided with a T-valve in the middle of the pipeline of water bath and beaker, T-valve another road is divided into two pipelines by short tube and threeway and adds: pipeline is connected to filtrator successively, the membrane pump that discharges water, and the pipeline outlet is connected to wastewater barrel; Another pipeline is connected to successively pre-hot heater, adds the water membrane pump, and pipeline terminal is provided with filtering head, and filtering head is placed in water-purifying tank.
This automatic water changer can advance water to water bath or beaker by T-valve and switch with the two-way that discharges water: discharging water one the tunnel is that T-valve is to wastewater barrel; Intake one the tunnel is that water-purifying tank (filtering head) is to T-valve.Discharge water membrane pump with to add the water membrane pump be one-way pump, and its passage is closed when the barrier film air pump inoperative, thereby this system can realize the function of changing respectively water to water bath and beaker.Beaker meets the state-promulgated pharmacopoeia standard, and there are two kinds of flat and Spherical Bottom at a cup end, and beaker bottom is all with changing water nozzle.
Characteristics of the present utility model and beneficial effect be, only need have 2 buckets, and the conversion by valve after each experiment can be changed water.Apparatus structure is simple, be convenient to clean, and meets the state-promulgated pharmacopoeia standard, can effectively alleviate the labour intensity of experiment operator.Three-way valve is made as electromagnetic valve, controls at instrument " discharging water " and " adding water " button is set on plate, can reach the purpose of automatic water-replacing.
Description of drawings
Shown in accompanying drawing be system architecture sketch of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Automatic water changer in the medicine detector, its structure is (as figure): be provided with a T-valve 3 in the middle of the pipeline of water bath 1 and beaker 2, another road of T-valve is divided into two pipelines by short tube and threeway: pipeline is connected to filtrator 4 successively, the membrane pump 5 that discharges water, and the pipeline outlet is connected to wastewater barrel 6; Another pipeline is connected to successively pre-hot heater 7, adds water membrane pump 8, and pipeline terminal is provided with filtering head 9, and filtering head is placed in water-purifying tank 10.The water bath bottom is with exchanging water hole.Glass end of beaker is flat, or Spherical Bottom, and beaker bottom is all with changing water nozzle.T-valve can be manually-operated gate, or electrically operated valve.
The membrane pump front end that discharges water adds filtrator and is used for preventing that the residue of the medicines such as capsule, tablet, dripping pill from stopping up water pump; Adding water membrane pump front end and install filtering head additional, is to prevent that impurity from stopping up water pump.Add water membrane pump rear end and be provided with pre-hot heater, can shift to an earlier date preheating, water temperature is heated up rapider, thereby shorten the time interval between twice experiment.The present embodiment T-valve is selected electromagnetic valve.
Claims (4)
1. the automatic water changer in the medicine detector, comprise water bath, beaker, T-valve, filtrator, the membrane pump that discharges water, wastewater barrel, pre-hot heater, add water membrane pump, filtering head and water-purifying tank, it is characterized in that: at the middle T-valve (3) that is provided with of water bath (1) and the pipeline of beaker (2), another road of T-valve is divided into two pipelines by short tube and threeway and adds: a pipeline is connected to filtrator (4), the membrane pump that discharges water (5) successively, and the pipeline outlet is connected to wastewater barrel (6); Another pipeline is connected to successively pre-hot heater (7), adds water membrane pump (8), and pipeline terminal is provided with filtering head (9), and filtering head is placed in water-purifying tank (10).
