Abstract

The utility model relates to an automatic bead washer which can be used for the wash of small beads with the use of detection and test. The utility model is composed of a casing solenoid valve, a water injection nozzle, a water inlet, a round response disc, a response cover, a tray, a rubber cap, a tube used for exhaust of waste liquid, a power supply circuit, a control circuit, an electrical machine, etc. The packed small beads are put into the cylinder of the response disc, waiting for the response; after the response, the power supply is switched on to make the control circuit and the electrical machine start to work. According to the edited program, the electrical machine drives the response disc to rotate with the use of centrifugal force theory; the washing of the beads through the vibration and rotating of injected water until the cleaning and drying of the beads. The utility model has the advantages of low labor intensity, short time, and avoids errors and enhance the accuracy of test result for the uniform washing effect.

Description

Automatic bead washer

The utility model belongs to the cleaning equipment in medical treatment detection and the immunoassay.

In medical treatment detection and immunoassay, be to being that the solid-phase immunity of carrier is analyzed with little ball.In the detection, the little ball that sample or label and bag are carried on the back carries out remnant or other impurity being arranged after association reaction finishes on little ball, after only cleaning up, and aptitude test.Therefore in the laboratory or the research department, washing this little ball is an extremely loaded down with trivial details job, generally all is with grain of hand control water inlet pipe globule to be cleaned, again with vacuum pump with the waste liquid sucking-off, with thieving paper globule moisture is dried.This manual way of cleaning little ball is required great effort again, and is time-consuming again, if the sample washing is unclean, occurs Error and Assay and pollution easily, and causes the mistake of chemical examination conclusion.

The purpose of this utility model is to design a kind of automatic bead wahser, and it adopts centrifugal principle, by control circuit, automatically little ball is cleaned.

The purpose of this utility model is achieved in that automatic bead wahser by solenoid valve, water-filling nozzle, water inlet, circular reaction tray, reaction disk cover, pallet, rubber bowl, compositions such as removal waste fluid pipe, power supply, control circuit, motor.Little ball to be washed is put into reaction tray, built disk cover, energized, motor and control circuit are started working.The rotation of motor drives reaction tray and rotates, and according to the program that microcomputer control circuit is finished, utilizes centrifugal principle, the not bond on the little ball in the dish is cleaned the back dry, and reaches the optimum efficiency of washing.

In conjunction with the accompanying drawings, specify as follows:

In the accompanying drawing 1,1 is automatic bead wahser casing, is being screwed motor frame 2 on the chassis base and motor 3 is installed.Connect Rotary cloumn 4 on the machine shaft, be screwed pallet 5 on the column, pallet 5 circumference have an equidistant 20-50 concave hole.Putting circular reaction tray 6 on pallet 5, reaction disk cover 7 covers on reaction tray 6, and reaction disk cover center has water inlet 8.Rubber cup 9 bottom center are passed Rotary cloumn 4, make the column first half, pallet, reaction tray, reaction disk cover all in rubber cup 9.Bead wahser loam cake 10 is equipped with in the rubber cup upper shed.Water-filling nozzle 11 probes in the rubber cup through solenoid valve 12 and loam cake 10, aims at the water inlet 8 of reaction disk cover.The rubber cup bottom has flatly, and the waste discharge water pipe 13 of ining succession directly stretches out outside the casing, is used for waste discharge.Casing one side is being screwed control circuit board 14, and the casing opposite side is being screwed localpower plate 15.

Among the accompanying drawing 2-4, circular reaction tray 6 is made up of interior disk 16 and cylindrical anchor ring 17, and the cylindrical anchor ring is higher than interior disk.What have equidistantly on the circumference of anchor ring 17 outside that 20-50 can put little ball deposits pearl cylinder 18.The last plane of disk 16 in the cylinder first half exceeds, the lower plane of disk 16 in Lower Half is longer than.When reaction tray 6 is placed on the pallet 5, deposit the shrinkage pool that pearl cylinder 18 can be put into pallet 5 just.Deposit pearl cylinder 18 and partly have open type water inlet inboard aperture 19, disk in this Kong Kaizhi towards interior disk; Depositing of interior disk has draining apertura lateralis 20 on the pearl cylinder dorsad.Apertura lateralis 20 is more higher than the position of inboard aperture 19.Be fixation reaction disk cover 7, on the interior disk 16 of circular reaction tray 6, be bonded with three equidistant columns 21, column is higher than cylindrical anchor ring 17.

In accompanying drawing 5-6, reaction disk cover 7 circumference are greater than reaction tray 6, have three round holes 22 with column 21 corresponding sections on the reaction tray inner plane, reaction covers 7 with to deposit pearl cylinder 18 highly consistent, reaction is covered on reaction tray, column 21 stretches out from circle hole 22, and reaction tray and reaction lid organically are linked together.Reaction disk cover center punches, and is bonded with hollow circuit cylinder along the hole, is called water inlet 8.

In accompanying drawing 7, the 220V alternating current by the integrated stable voltage circuit voltage stabilizing, uses for the each several part circuit behind transformer secondary output output, rectifying and wave-filtering.Wherein the output voltage of voltage stabilizing sheet 23 power supply magnet valve power supply uses; The output voltage of voltage stabilizing sheet 24 uses for the relay of control motor, relay, microcomputer control circuit and the drive power supply of control electromagnetic valve; The output voltage of voltage stabilizing sheet 25 uses for computer power and buzzer.

In the accompanying drawing 8, control circuit is made up of conventional control circuit.Comprising: single chip microcomputer chip 26, latch 27, ROM reservoir 28, reverser 29, driver 30.The program that utilization is finished, motor 3 is rotated, being placed on the sample or the label that react on the little ball of taking inventory in the pearl cylinder 18 is gone out by centrifugal usefulness, control circuit makes solenoid valve open water-filling nozzle 11, water flows on the interior disk 16 of reaction tray by loam cake 10, water inlet 8, along inboard aperture 19, flow to and deposit in the pearl cylinder 18.Under the drive of motor, reaction tray rotation vibrations, the globule of depositing in the pearl cylinder 18 to be washed is constantly washed by water, under action of centrifugal force, water purification constantly injects deposits the pearl cylinder, and centrifugal the throwing away from apertura lateralis 20 of the sewage in the cylinder, and outside waste discharge water pipe 13 discharge casings.So repeatedly several times after, globule is cleaned, control circuit makes closed electromagnetic valve water-filling nozzle 11 again, motor continues rotation, still utilizes centrifugal principle, the moisture content centrifuge dripping on the globule, reaches dry purpose.Washing finishes, and automatic control circuit makes buzzer send sound equipment, and pilot lamp glitters simultaneously, cleans and finishes.

Automatically bead wahser adopts the method for control automatically to wash pearl, has saved testing staff's plenty of time, has alleviated labour intensity, has prevented the error that hand washing causes.And washed globule can be dried simultaneously.The 20-50 of reaction tray deposits the pearl cylinder and also can be used to do reaction in addition, and is after reaction finishes, just capable of washing.Because cleaning performance is good, improved the accuracy of testing result.
