Description

The ultrapure water machine that possesses the detection alarm function of leaking

Technical field

The utility model relates to ultrapure water and prepares equipment, particularly adopts RO reverse osmosis technology, ultrapureization of UP nucleon level technology, UF ultra-filtration technique and various on-line monitoring technique to produce the ultrapure water machine of laboratory with ultrapure water.

Background technology

Present laboratory does not also have simultaneously onlinely to detect machine intimate technology that leak and Realtime Alerts with in the ultrapure water machine industry.

The utility model content

The purpose of this utility model provides a kind of ultrapure water machine that possesses the detection alarm function of leaking, and with the operating state of on-line monitoring machine at any time, in time sends chimes of doom if any leaking and reminds the user, avoids causing because of leaking laboratory loss.

This novel purpose is achieved in that a kind of ultrapure water machine that possesses the detection alarm function of leaking, comprise placing in the casing, connecting polypropylene filter, AC activated charcoal filter, accurate filter, reverse osmosis membrane processing device, mixed ion exchanger, polishing in turn by pipeline and mix bed, UV ultraviolet sterilization instrument and UF ultimate filter and form ultrapure water machine also have the detection alarm of leaking circuit:

Central processing unit: mainly form, finish processing computing, and output to led display unit in the mode of order to input signal by Chip Microcomputer A LT89852;

Two chip blocks (DZ420) transmitter: be arranged on low-lying place in the described casing;

Analog conversion module: be connected with two chip block transmitters, accept conductance signal and temperature signal that two chip block transmitters are sent here, and send after converting this conductance signal and temperature signal to voltage signal and current signal;

The A/D converting unit: mainly be made up of chip ADC0832, voltage signal and current signal that analog conversion module is sent convert corresponding numerary signal to, and export Chip Microcomputer A LT89852 to;

Led display unit: LT89852 is connected with Chip Microcomputer A, carries out the demonstration of complete machine function and state.

Above-mentioned led display unit is 128 * 64-ML liquid-crystal display or static LED indicating meter or dynamic LED indicating meter.

This is novel to be at certain two low-lying place, machine bottom two chip sensors to be set, there is not drainage as machine, two chips are to be in off-state, in case machine intimate leaks, two chips are in closure state because of the electroconductibility of water is communicated with, at this moment this chip will output signal be delivered to described central processing unit after the A/D converting unit, just directly occurs " machine leaks " printed words on the display screen of machine.

The beneficial effects of the utility model are:

1, the situation of leaking of machine intimate is carried out on-line real time monitoring, and reflect by the LED demonstration.

2, do not know again as the machine user of leaking, can make the machine main plate short or burn the every loss that causes whole equipment heavy losses or laboratory to be flooded; The art of this patent has then thoroughly solved these losses, allows carefree this machine of use of user.
