Abstract
The invention aims to overcome the disadvantages in the prior art and provides a novel mixing device that is easy to operate and good in universality and has temperature display function by integrating a stirrer and a temperature meter. The novel mixing device avoids the problems that the prior art has strict requirement for volume and viscocity of a material system to be mixed, the temperature meter can not be contact directly with the system to be measured to protect the temperature meter from corrosion and mechanical wear by the material system. The stirrer rotates mechanically and converts the mechanical energy partially into the electric energy, to supply power to the temperature meter under stirring conditions. The temperature meter is powered by an external power supply under static conditions. The device smartly solves the problem simply caused by power supply of battery.
Description
Technical field
A kind of novel can be in whipping process self-powered and the agitating device by thermal resistance or thermocouple measurement system temperature, be applied to fields such as chemistry, physics, biological medicine, food processing.
Background technology
Stirring operation and temperature are controlled at fields such as chemistry, physics, biological medicine, food processing and have a wide range of applications.Two kinds of operations are all finished by two independent device.With the reactor of using in the chemical industry production is example, and reload temperature measuring guide on reactor is normally adopted in temperature survey, adds conduction oil in the pipe, measures the temperature of reaction system then with mercurial thermometer or alcohol thermometer.Generally speaking, this mode can meet the needs of production.But adopt this mode to have the following disadvantages: (1) is limited to the length of warm conduit when the reaction system liquid level is low, the temperature measuring meeting is met difficulty, and usually adopts non-standard equipment, solves as reactor being taked the mode of STH.When (2) the big and mixing speed of reaction system viscosity is very fast, warm conduit can produce crooked because of moment is bigger in addition with the pad cracking of still mouth.Application number is 2007100433775, described to adopt among the 200710043378X, 2007100943320 patent agitator and temperature measuring equipment are integrated, and can effectively solve the problem that above-mentioned conventional temperature measuring method runs into.But the temperature measuring equipment that above patent relates to is selected powered battery for use, and following two defectives are arranged: the one, and the working environment of general battery can not be too high, and for pyroreaction, the shaft temperature is higher, uses battery commonly used that the danger of blast is arranged; The 2nd, the service life of general battery is shorter, and to those situations that requires the long-time continuous stirring operation, use is restricted.
Summary of the invention
Main purpose of the present invention is to overcome the prior art deficiency, and the present invention integrates agitator and temperature reading device, the novel mixing plant that provides a kind of convenience, general band temperature to show.This novel agitator can be avoided conventional agitator to carrying out the requirement of stirring operation to factors such as material system volume, viscositys.Simultaneously, temperature measuring equipment does not directly contact with the survey environment, avoids expecting the infringements such as burn into mechanical wear to temperature measuring equipment.
Utilize the mechanical rotation of agitator own, part mechanical energy is converted into electric energy, for temperature measuring equipment is powered under stirring.Adopt the external power supply power supply under the inactive state.This device has solved the simple battery-powered and deficiency that causes dexterously.
The agitator that the present invention relates to is a mechanical stirrer.The temperature measuring equipment that the present invention relates to is thermal resistance, thermocouple temperature sensor.The self-power supply device that the present invention relates to is the magnetic induction TRT.
This novel agitator whipped form comprises dasher, opens turbine type, disc turbine formula, pusher Bu Lumajinshi, three leaf swept-backs, MIG formula, INTER-MIG formula, sawtooth disc type, triangle oscillating type, anchor formula, helical-ribbon type, screw etc.
According to different purposes and purpose, can select for use ordinary steel, stainless steel, special steel, special alloy, high-strength corrosion-resisting heatproof plastics, glass etc. to make this novel agitator for material.The agitator that uses in industrial production is material with ordinary steel, stainless steel, special steel, special alloy, and can select high-strength corrosion-resisting heatproof plastics, glass in the scientific research of laboratory except that above-mentioned material for use is material.
Shaft can be hollow material, also can be solid material.When shaft was hollow material, the hollow space pore size was a principle with the intensity that guarantees shaft, adjusted as required, and claimed heatproof insulating material as required.When using glass tube to do shaft, except that selecting suitable glass material for use, guarantee that glass tube has enough thickness, make not easy fracture of shaft.When shaft is solid material, need axially to install conduit additional along shaft, the call wire that is used for thermal resistance and instrument is introduced or is drawn.The call wire that is used to draw or introduce thermal resistance and instrument in the boring of shaft sealing station.
Have different connected modes according to different whipped forms with unlike material shaft and paddle.The dasher of employing metal material, unlatching turbine type, disc turbine formula, pusher Bu Lumajinshi, three leaf swept-backs, sawtooth disc type, triangle oscillating type, anchor formula stir its shaft and adopt modes such as screw thread, welding to be connected with the paddle band, intermediate cryptographic gasket when adopting thread connecting mode.MIG formula, INTER-MIG formula, helical-ribbon type, screw shaft bottom increase by one section sealing cap by modes such as screw thread, forging castings, add gasket seal between sealing cap and the shaft when adopting thread connecting mode.When adopting glass to be the material preparation agitator, be connected mode with rib-loop or burn-back.
Temperature measuring equipment can be the resistance and temperature induction installation.Existing most widely used thermal resistance material is platinum and copper.Its output signal is big, measures accurately, is convenient to teletransmission.With balanced bridge or the supporting use of unbalanced bridge, can show, write down and realize multimetering automatically.The principle schematic of thermal resistance is shown in Figure of description 1.
Temperature measuring equipment also can be the electric thermo-couple temperature induction installation.Thermocouple has simple structure, and the Applicable temperature scope is wide, characteristics such as bear heat, the mechanical shock ability is strong, and response speed is fast.The principle schematic of thermocouple is shown in Figure of description 2.According to different purposes, thermocouple can be chosen different models.
Thermal resistance or thermocouple connect lead and place the shaft hollow position.Thermal resistance places the bottom or the middle and lower part of agitating device hollow space, and temperature of charge is representative to be as the criterion to measure.Simultaneously can be according to circumstances add a small amount of conduction oil in the hole again or metal fillings is made heat transfer medium.
When shaft satisfies certain size, can will show that direct instrument is fixed on the shaft.This situation requires the Displaying Meter miniaturization, and the mode that adopts numeral to show is carried out reading.If the shaft size can not satisfy fixedly Displaying Meter, can between shaft and stirring motor, connect by a jockey, instrument and jockey integrate.
Self-power supply device is the magnetic induction TRT, utilizes the mechanical rotation of agitator own, and part mechanical energy is converted into electric energy, powers under stirring for temperature measuring equipment, and principle schematic is shown in Figure of description 3.The next employing external power supply power supply of inactive state.
