Abstract
The utility model relates to a water sample pretreatment device, in particular to an integrated filtering device in a water sample pretreatment system, and mainly solves the technical problem that internal structural members of a conventional water sample pretreatment system cannot be cleaned. The technical scheme of the integrated filtering device is as follows: the integrated filtering device in the water sample pretreatment system comprises a sand basin, a sample reserving cup, a filter, a peristaltic pump, a sample reserving cup liquid level switch and a sand basin drain valve, wherein an inlet end of the peristaltic pump is connected with the filter in the sand basin; and an outlet end of the peristaltic pump is connected with the sample reserving cup; the integrated filtering device is characterized in that a cleaning valve is arranged on a connecting pipeline of the sand basin and the peristaltic pump; and a sample reserving cup cleaner connected with the cleaning valve is arranged in the sample reserving cup. In order to control the liquid level of the sand basin, an upper sand basin liquid level switch and a lower sand basin liquid level switch are arranged at the upper part and the lower part of the side wall of the sand basin. The integrated filtering device in the water sample pretreatment system is mainly applied to pretreatment during water sample detection.
Description
Technical field
The utility model relates to water sample preprocessing apparatus, particularly the integrated filter device in a kind of water sample pretreatment system.
Background technology
Chinese patent application 201110100224.6 discloses " a kind of water sample convey device in water sample pre-treatment system ", comprise sand basin, water sample cup and be placed in the level switch of described water sample cup, the entrance point that it is characterized in that peristaltic pump is connected with the filter core in being installed on sand basin, and the endpiece of described peristaltic pump is connected with water sample cup.Although this device adopts peristaltic pump to have advantages of failure rate is low and pollution water sample not as transmitting power, because this device does not arrange cleaning device, after long-time the use, internal part easily pollutes, if replacing in time causes again cost, height is looked forward to.
Summary of the invention
The purpose of this utility model is to provide a kind of more reliable performance, and structure is simpler, and the integrated filter device in the water sample pretreatment system of easy maintenance.Mainly solve existing water sample pretreatment system and have the technical matters that internally structure member is cleaned.
For achieving the above object, the technical solution adopted in the utility model is: the integrated filter device in a kind of water sample pretreatment system, comprise sand basin, Cup for holding sample, filtrator, peristaltic pump, Cup for holding sample level switch and sand basin discharge valve, the peristaltic pump entrance point is connected with the filtrator in sand basin, the peristaltic pump endpiece is connected with Cup for holding sample, it is characterized in that: establish the gas cleaning valve on sand basin and peristaltic pump connecting line, settle the Cup for holding sample washer be connected with cleaning valve in Cup for holding sample.For controlling the sand basin liquid level, level switch under level switch and sand basin is established on sand basin in sand basin sidewall top and the bottom.
The beneficial effects of the utility model: 1) simple in structure, reliable, failure rate is low.2) adopt anticorrosive material to be applicable to surface water and the pollution source of various different quality conditions.3) crossing filter core can be selected according to water condition, meets different filtering accuracy requirements.4) can be according to the cleaning that condition is set automatically completes Cup for holding sample and filtrator.5) can not cause secondary pollution to measured water sample.6) pretreated sample introduction and discharge are all completed by peristaltic pump, greatly reduce trouble spot.7) with low cost, be convenient to safeguard.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, the 1-sand basin; Level switch on the 2-sand basin; The 3-filtrator; Level switch under the 4-sand basin; 5-sand basin discharge valve; 6-gas cleaning valve; The 7-peristaltic pump; The 8-Cup for holding sample; 9-Cup for holding sample washer; 10-Cup for holding sample level switch; The 11-cleaning valve.
Embodiment
As shown in Figure 1: the integrated filter device in a kind of water sample pretreatment system, comprise sand basin 1, Cup for holding sample 8, filtrator 3, peristaltic pump 7, Cup for holding sample level switch 10, sand basin discharge valve 5, peristaltic pump 7 entrance points are connected with the filtrator 3 in sand basin, peristaltic pump 7 endpiece are connected with Cup for holding sample 8, establish gas cleaning valve 6 on sand basin 1 and peristaltic pump 7 connecting lines, settle the Cup for holding sample washer 9 be connected with cleaning valve 11 in Cup for holding sample 8.For controlling the sand basin liquid level, level switch 4 under level switch 2 and sand basin is established on sand basin in sand basin sidewall top and the bottom.
In pre-service when operation,, water sample enters sand basin 1, while reaching on sand basin level switch 2, stops sample introduction, carries out standingly, and after standing completing, the water sample supernatant is extracted in peristaltic pump 7 operations from high-precision filtration core 3.Water sample is after high-precision filtration core 3 filters, and in input Cup for holding sample 8, after Cup for holding sample level switch 10 reaches high liquid level, peristaltic pump 7 is out of service, and water sample is offered to instrumental analysis.After analysis completes, peristaltic pump 7 reversions are discharged Cup for holding sample 8 by residual water sample, cleaning valve 11 is opened Cup for holding sample 8 is cleaned simultaneously, and after cleaning, gas cleaning valve 6 is opened, high-precision filtration core 3 is cleaned, open sand basin discharge valve 5 simultaneously, residual water sample is discharged to sand basin 1, water sample reaches under sand basin after level switch 4, time delay discharge 2 minutes, guarantee whole water samples discharges.
Claims (2)
1. the integrated filter device in a water sample pretreatment system, comprise sand basin, Cup for holding sample, filtrator, peristaltic pump, Cup for holding sample level switch and sand basin discharge valve, the peristaltic pump entrance point is connected with the filtrator in sand basin, the peristaltic pump endpiece is connected with Cup for holding sample, it is characterized in that: establish the gas cleaning valve on sand basin and peristaltic pump connecting line, settle the Cup for holding sample washer be connected with cleaning valve in Cup for holding sample.
