Abstract
A device for measuring the COD (chemical oxygen demand) content of sewage comprises a casing, a plurality of heating stoves arranged in the casing, a main control panel and a heating bottle. The device is characterized in that a temperature sensor is arranged in each heating stove; a liquid crystal display is arranged on the front surface of the casing; the temperature sensors are electrically connected with the liquid crystal display and are electrically connected with the main control panel through a switch; a timing circuit is arranged on the main control panel; and a manually-driven setting button is arranged on the surface of the casing correspondingly. The liquid crystal display displays the temperature value of each heating stove more intuitively; the main control panel controls the heating stoves to stop heating according to the signals of the temperature sensors and the time preset by the timing circuit; each heating stove can work independently; full-automatic control can be realized through the main control panel; the heating stoves can also work at the same time as well as work independently, thereby facilitating power saving and apparatus protection and prolonging the service life of the apparatus; moreover, the automation control degree is high; and the operation is simpler.
Description
Technical field
The utility model relates to a kind of determination of sewage device, specifically is a kind of device of measuring COD content in the sewage.
Background technology
Existing COD of sewage content testing device mostly is the setting of single hole list kitchen range, can not carry out clearing up and measuring of a plurality of samples simultaneously.Though what have establishes the many kitchen ranges of porous, temperature sensor only is provided with one, and single kitchen range can not work independently, and must work simultaneously by a plurality of heating-ranges, is unfavorable for economize on electricity, and dry combustion method appears in heating-range useless, and instrument is had certain infringement.Also have, temperature shows not directly perceived, is not easy to observation.Automaticity is not high yet in addition.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of COD of sewage content testing device, and its heating-range can be worked simultaneously, also can work independently, and realize control automatically, operates simpler.
The technical solution of the utility model is: this COD of sewage content testing device comprises housing, is arranged on heating-range, main control panel, heating bottle in the housing; Heating-range is provided with a plurality of, and a temperature sensor is set in each heating-range, and the housing front surface is provided with a LCDs; Each temperature sensor is electrically connected with this LCDs, and each temperature sensor is electrically connected with main control panel by a switch respectively; Main control panel is provided with timing circuit, and the surface of shell correspondence is provided with manual setting button.
As further technical scheme of the present utility model:
In this COD of sewage content testing device, the kitchen range chamber diameter of described heating-range is 50-70mm, highly is 50-70mm.
The temperature value of LCDs each heating-range of demonstration more directly perceived, main control panel is according to the heating that stops of the default time control heating-range of signal, the timing circuit of temperature sensor.Each heating-range all can work independently, and realizes Automatic Control by main control panel.
The beneficial effects of the utility model are: its a plurality of heating-ranges can be worked simultaneously, also can work independently, and help power saving and protection instrument, prolong the serviceable life of instrument, and the automatic controlling level height, operate simpler.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is a front view of the present utility model,
Fig. 2 is a vertical view of the present utility model,
Fig. 3 is a left view of the present utility model,
Among the figure: 1 housing, 2 heating-ranges, 21 kitchen range chambeies, 3 temperature sensors, 4 LCDs, 5 switches, 6 manually set button.
Embodiment
As shown in Figure 1, 2, 3, this COD of sewage content testing device comprises housing 1, is arranged on heating-range 2, main control panel, heating bottle in the housing.Heating-range 2 is provided with a plurality of, and a temperature sensor 3 is set in each heating-range, and the housing front surface is provided with a LCDs 4.Each temperature sensor 3 is electrically connected with this LCDs 4, and each temperature sensor is electrically connected with main control panel by a switch respectively; Main control panel is provided with timing circuit, and the surface of shell correspondence is provided with manual setting button 6.Kitchen range chamber 21 diameters of heating-range are 50-70mm, are 50-70mm highly, and usable range is wide.During manufacturing, the cover of heating-range can be the cast aluminium workpiece.
The same prior art of all the other technology.
