Abstract
The invention discloses an automatic control system of a constant-temperature water tank. The automatic control system of the constant-temperature water tank comprises the constant-temperature water tank and a controller. The automatic control system of the constant-temperature water tank is characterized in that a heater is arranged at the bottom part of the constant-temperature water tank; an agitating device connected with an agitating motor is arranged in the constant-temperature water tank; a water storing tank is connected to the bottom part of the constant-temperature water tank through a first water pump; an upper level detector, a lower level detector and a first temperature detector are also mounted on the constant-temperature water tank and are respectively connected with a main controller by signals; the first water pump and a switching circuit of the agitating motor are respectively electrically connected with the main controller. The automatic control system of the constant-temperature water tank has the advantages that the PID (Proportion Integration Differentiation) is performed for conditioning and heating, so that the constant temperature can be accurately controlled; the agitating device in the constant-temperature water tank enables the water temperature in the water tank to be basically kept consistent, and the uniformity of heating and high heating efficiency are ensured; the upper level detector and the lower level detector are arranged on the constant-temperature water tank, which can avoid the phenomena of running dry due to excessively low water level and overflowing due to excessively high level in the constant-temperature water tank.
Description
Technical field
The present invention relates to a kind of constant temperature water tank, particularly relate to a kind of constant temperature water tank automatic control system.
Background technology
Constant temperature water tank can supply the chemical examination department of the industries such as medical institutions, universities and colleges, scientific research, chemical industry, printing and dyeing to do to distill, dry, concentrated and heated at constant temperature chemicals and biological article constant temperature culture, and apparatus is carried out to the extensive use such as use of scalding.Constant temperature water tank of the prior art be that water is heated to store after uniform temperature through heating source, when naturally cooling to below this temperature, Automatic-heating.But existing constant temperature water tank is low because of temperature control precision, exists and takes electricity and hidden danger, sometimes also occur dry combustion method phenomenon; In addition, the heater in constant temperature water tank of the prior art is generally positioned at certain fixed position in water tank, and there will be the water temperature of each position in water tank so inconsistent, the efficiency of heating surface is lower.
Summary of the invention
The object of the invention is for deficiency of the prior art, a kind of constant temperature water tank automatic control system is provided, accurately can controls steady temperature, and water temperature everywhere can be made in constant temperature water tank to be substantially consistent.
The object of the present invention is achieved like this: a kind of constant temperature water tank automatic control system, comprises constant temperature water tank and controller, and the bottom of described constant temperature water tank is provided with heater, is provided with the agitator be connected with stirring motor in constant temperature water tank; Storage tank is connected with by water pump one bottom constant temperature water tank; Described constant temperature water tank is also provided with liquid level detector, lower liquid level detector and temperature detector one, described upper liquid level detector, lower liquid level detector and temperature detector one are connected with described master controller signal respectively; Described water pump one is electrically connected with master controller respectively with the on-off circuit of stirring motor.
Control procedure of the present invention is as follows: when after design temperature, start water pump one to intake in constant temperature water tank, waterborne be raised to liquid level after, start stirring motor, measure water tank water temperature and also compare with setting value, if water temperature is higher than setting value, then open magnetic valve one, water filling in constant temperature water tank, if water temperature is lower than setting value, then heater and stirring motor, adds thermal agitation until reach setting value to the water in water tank.Compared with prior art, the invention has the beneficial effects as follows: adopt PID to regulate heating, accurately can control steady temperature; Be provided with agitator in constant temperature water tank, water temperature everywhere can be made in water tank to be substantially consistent, and homogeneous heating, the efficiency of heating surface are high; Constant temperature water tank is provided with liquid level detector and lower liquid level detector, avoids occurring that constant temperature water tank occurs that water level is too low and causes dry combustion method and the too high phenomenon causing overflowing of water level.
As a further improvement on the present invention, described storage tank is also connected with condenser by water pump two, and described condenser is connected with described constant temperature water tank by feed pipe, and the on-off circuit of described water pump two is electrically connected with master controller.When water ultra-temperature is in set water temperature, water pump one and water pump two can be opened to constant temperature water tank water filling cooling simultaneously, realize fast cooling.
As a further improvement on the present invention, described feed pipe is also provided with flow detector and temperature detector two, described temperature detector two is arranged at the water outlet of feed pipe.Whether the setting of flow detector is convenient to detect supply channel and is occurred supplying water extremely, and temperature detector, second for detecting feed pipe to water filling temperature in constant temperature water tank, being convenient to detect condenser and whether being there is exception.
As a further improvement on the present invention, the bottom of described storage tank is provided with ultra low water level alarm.When ultra low water level appears in storage tank, ultra low water level alarm sends alarm signal, notifies that staff is to water filling in storage tank.
