The specific embodiment
Below in conjunction with accompanying drawing the utility model is done description in further detail:
Cleaning waterworks of the present utility model as shown in Figure 1, these cleaning waterworks comprise high-pressure magnetic pump, distilled water volumetric flask, cleaning needle and floor push, adopt the high-pressure magnetic pump that distilled water is injected adsorption column by cleaning needle, can control the confluent of distilled water in the cleaning process by floor push.
Waste liquid recovery apparatus of the present utility model as shown in Figure 2, this waste liquid recovery apparatus comprises vacuum suction filter pump, waste liquid returnable bottle and pressure-regulating valve, aspirate by the negative pressure that the vacuum suction filter pump produces, make waste liquid and discarded object all be recovered in the waste liquid returnable bottle, the silica gel of recovery can repeat to utilize through processing again.
An embodiment of the utility model adsorption column cleaning machine as shown in Figure 3, the aspiration rate of vacuum suction filter pump is 0.6L/min, end vacuum is 6 * 10
-6Pa; The high-pressure magnetic pump lift is 10m, and pressure is 2～3kg; The capacity of distilled water volumetric flask 2 is 1L, the band dust cap; The capacity of waste liquid returnable bottle 3 is 1L, with closure; The aperture that waste liquid recovery line 6 and distilled water clean pipeline 10 is Φ 4mm and Φ 6mm, and corrosion-resistant, bearing pressure is 5kg; The aperture of three-way pipe, straight pipe is Φ 6mm, and is corrosion-resistant, and bearing pressure is 5kg; The special-purpose cleaning needle of adsorption column is long to be 1.5m, and the aperture is Φ 0.2mm.
The pipeline of adsorption column cleaning machine connects as shown in Figure 3, at first the suction strainer interface of adsorption column cleaning machine main body 1 is connected with any interface of waste liquid returnable bottle 3 loam cakes (two interfaces) totally, another interface with waste liquid returnable bottle 3 loam cakes connects the first waste liquid recovery line 6-1 and the second waste liquid recovery line 6-2 respectively by waste liquid recovery three-way pipe 5 then; The first waste liquid recovery line 6-1 is connected to adsorption column lower end bead bistrique interface,, must extracts the absorbent cotton between bead bistrique and the adsorption column before cleaning the feeding section the inside that the second waste liquid recovery line 6-2 directly is inserted into the adsorption column upper end; The delivery port of distilled water volumetric flask 2 is connected to water inlet interface on the adsorption column cleaning machine main body 1, then the distilled water volumetric flask 2 that cleans up is filled distilled water (about 1000mL); Cleaning interface on the adsorption column cleaning machine main body 1 and distilled water are cleaned pipeline 10 be connected, and be connected with the special-purpose cleaning needle of adsorption column by straight-through.
