Description
Technical field
The utility model relates to the on-the-spot detection range of wastewater treatment water quality, thereby particularly can protect the PH meter and possess automatic cleaning function, prolong PH meter serviceable life, guarantee that by regularly purging accuracy of detection guarantees normal operation of wastewater treatment and safety dumping.
Background technology
In the water treatment field of industrial and mining enterprises such as metallurgy, chemical industry, papermaking, all relate to online water quality detection.In water treatment procedure, in order to guarantee the effect of water treatment, must in water treatment procedure, adjust, and the foundation of adjusting is exactly online water-quality guideline water technology, parameter.Therefore according to the water technology demand, must carry out online detection to required water-quality guideline.
The online PH meter of existing field of waste water treatment is generally card edge type; without any protective device; be that the PH meter directly inserts in water treatment pipeline or the pond; this mode PH meter subject to damage; because being mainly glass material, the PH meter forms; and very thin thickness, 1.5 millimeter only are so be subjected to very easily that the foreign material bump causes the PH meter to damage in the water.
China Patent No. CN200610147470.6 discloses " pH meter self-stripping system and system flow thereof in the desulfuration absorbing tower ".This device major function is for cleaning the foul be attached on PH meter probe, and it needs two cover PH meter and cleaning devices, normal a use, and another is in the work that substitutes under the cleaning state at one, and it is longer to clean required time, and complex process needs the PLC control system.And this device is only applicable to not have the occasion of particle impurity owing to there is not PH meter safeguard measure.
Summary of the invention
The purpose of this utility model is to design a kind of PH meter protector that possesses automatic cleaning function; PH in the reduction jar that cold rolling wastewater can be handled counts and protects, thereby prolongation PH counts serviceable life, guarantees that by regularly purging the assurance accuracy of detection wastewater treatment normally moves and safe qualified discharge.
For achieving the above object, the technical solution of the utility model is,
A kind of PH meter protector that possesses automatic cleaning function, it comprises, body, it has a cavity body structure, and the two side is a filter screen; Its upper wall has the installation through hole of planting for the PH meter; Accordingly, its lower wall has a connecting through hole; The protection back-up ring, the hollow cylindrical structure is arranged at upper wall in the body cavity, the corresponding through hole of installing; Two guide rails are arranged at protection back-up ring both sides respectively; Piston opens and closes the chamber, is arranged at body cavity lower inner wall, below, the lower wall connecting through hole place of corresponding protection back-up ring; Piston is arranged at piston and opens and closes indoorly, and an over cap is established in its upper surface, and these over cap both sides cooperate with the protection back-up ring against two guide rails, form the confined space that can protect PH meter and body cavity to completely cut off; Compressed air hose, one termination are located at piston and are opened and closed the chamber, but the air that Nei Tong pushing tow piston rises along guide rail; The cleaning scavenging duct, insert respectively be arranged in the body cavity, corresponding two side filter screen, have purge hole along the corresponding filter screen of pipe shaft one side; Be communicated with compressed air hose by a connecting pipe on it.
Further, described body is a cylindrical shape.
Also establish the fixedly fastening bolt of PH meter in the installation through hole described in the utility model.
Described piston opens and closes indoor connecting through hole place and sets up defences also only that piston drops to the spacing back-up ring that minimum point slips into compressed air hose.
The beneficial effects of the utility model:
By the utility model device is installed, the PH meter has obtained excellent protection: guaranteed that PH meter probe is not sticked by subtitle substance, has avoided the distortion as a result of PH instrumentation amount; Protect PH meter not to be subjected to that particle clashes in the water, prolonged the serviceable life of PH meter significantly.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is a working state schematic representation of the present utility model;
Embodiment
Referring to Fig. 1, the PH meter protector that possesses automatic cleaning function of the present utility model, it comprises, and body 1 is cylindrical shape, and it has a cavity body structure 100, and the two side is a filter screen 101,102; Its upper wall has the installation through hole of planting for PH meter 10 103; Accordingly, its lower wall has a connecting through hole 104;
Protection back-up ring 2, the hollow cylindrical structure is arranged at upper wall in body 1 cavity 100, the corresponding through hole 103 of installing;
Two guide rails 3 are arranged at protection back-up ring 2 both sides respectively; Piston opens and closes chamber 4, is arranged at body 1 cavity 100 lower inner walls, below, lower wall connecting through hole 104 places of corresponding protection back-up ring 2; Piston 5 is arranged in the piston keying chamber 4, and an over cap 51 is established in its upper surface, and these over cap 51 both sides cooperate with protection back-up ring 2 against two guide rails 3, forms the confined space that can protect PH meter and body cavity 100 to completely cut off; Compressed air hose 6, one termination are located at piston and are opened and closed chamber 4, but the air that Nei Tong pushing tow piston 5 rises along guide rail 3; Cleaning scavenging duct 7,7 ' inserts respectively and is arranged at body cavity 100 interior, corresponding two side filter screens 101,102, has purge hole 71,71 ' along the corresponding filter screen of pipe shaft one side; Be communicated with compressed air hose 6 by a connecting pipe 8 on it.
