Abstract
The utility model relates to a rapid-constant-temperature electric heating sleeve in a chemical experiment, which is suitable for various utensils including a round-bottom flask and the like. The rapid-constant-temperature electric heating sleeve is formed by an inner core of the electric heating sleeve, a shell, an axial flow fan, a temperature sensor, a connecting guide line and a controller. The inner core of the electric heating sleeve is mounted at the upper part of the shell and is semispherical; the axial flow fan is mounted at the bottom of the shell, and the inner core of the electric heating sleeve and the axial flow fan are connected with the controller through lead wires; and the temperature sensor is connected with the controller through the lead wire. According to the utility model, a heating part adopts a resistance wire covered in insulating layer glass fibers to heat a heated utensil; the heat efficiency is high and a heating source is directly contacted with a heated body to rapidly heat; and an overshoot phenomenon of a temperature is avoided in a heating process.
Description
Technical field
The utility model relates to a kind of fast constant temperature electrical heating cover that is used for vessel such as all kinds of round-bottomed flasks in the chemical experiment.
Background technology
It is very convenient and practical to use the electrical heating cover that vessel such as all kinds of round-bottomed flasks are directly heated in the chemical experiment, but the heater strip heating in the electrical heating cover heating part has certain hysteresis and a large amount of waste heats, can the occurrence temperature overshoot phenomenon during experiment.Design a kind of fast constant temperature electrical heating cover and satisfy very necessity of all kinds of chemical experiment heated at constant temperature.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art; A kind of fast constant temperature electrical heating cover that is used for vessel such as all kinds of round-bottomed flasks in the chemical experiment is provided; Satisfy in the chemical experiment vessel fast constant temperature heating commonly used, and overshoot phenomenon does not appear in its temperature when realizing heating.
The technical scheme of the utility model is:
The utility model is a kind of fast constant temperature electrical heating cover, is made up of electrical heating cover inner core, shell, aerofoil fan, temperature sensor, connection lead and controller.Said electrical heating cover inner core is installed in shell upper, is hemispherical; At outer casing bottom aerofoil fan is installed, electrical heating cover inner core links to each other with controller through being connected lead with aerofoil fan; Temperature sensor links to each other with controller through connecting lead.
The utility model utilization is wrapped in the heating of the intrastitial resistance wire of dielectric glass layer heats being heated vessel, utilizes temperature in the temperature sensor measurement reaction vessels of controller; Temperature control instrument is realized heater strip power supply of electrical heating cover and outage in the controller; Aerofoil fan in the shell of heating jacket dispels the heat in the time of under the effect of controller, can being higher than target temperature to the heating jacket heater strip; Quit work when being lower than target temperature; Heating and the collaborative work of dispelling the heat realize being heated the fast constant temperature of vessel.
The advantage of the utility model:
1, the utility model heating part adopts and to be wrapped in the intrastitial resistance wire heating of dielectric glass layer and to heat being heated vessel, and its thermal efficiency is high, and heating source directly contacts heated object, and heating rapidly; 2, heating jacket inner core bottom is equipped with radiator fan, when temperature is higher than target temperature, starts fast and heat radiation, avoids the heated object temperature overshot; 3, control instrument adopts the PID temp controlled meter, possesses intelligent computing firing rate and rate of heat dispation, guarantees hocketing of heating and heat radiation, realizes the fast constant temperature heating; 4, in the controller heating voltage and fan speed-regulating controller can be installed conveniently, guarantee that constant temperature also can carry out heating power and radiating rate simultaneously and regulate; 5, the sensor overcoat adopt the polytetrafluoroethylmaterial material preparation or not with the inert metal preparation of heating object reaction, be applicable to that various chemical experiments use; 6, it satisfies in 50 ~ 350 ℃ of scopes and all can realize fast constant temperature after heating jacket and the heat radiation coupling, effectively prevents temperature overshot.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of fast constant temperature electrical heating cover of the utility model.
1. electrical heating cover inner core among the figure, 2. shell, 3. aerofoil fan, 4. temperature sensor, 5. connection lead, 6. controller, 7. connection lead.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
In Fig. 1, a kind of fast constant temperature electrical heating of the utility model cover is made up of electrical heating cover inner core 1, shell 2, aerofoil fan 3, temperature sensor 4, connection lead 5, connection lead 7 and controller 6.Said electrical heating cover inner core 1 is installed in shell 2 tops, is hemispherical; In shell 2 bottoms aerofoil fan 3 is installed, electrical heating cover inner core 1 links to each other with controller 6 through being connected lead 7 with aerofoil fan 3; Temperature sensor 4 links to each other with controller 6 through connecting lead 5.Controller 6 adopts the PID temp controlled meter to carry out intelligent temperature control in use.
The utility model utilization is wrapped in the intrastitial resistance wire heating of dielectric glass layer heats being heated vessel, utilizes the temperature sensor 4 of controller 6 to measure temperature in the reaction vessels; Temperature control instrument realizes that to heater strip power supply of electrical heating cover and outage, the aerofoil fan 3 in the shell 2 of heating jacket dispels the heat in the time of can being higher than target temperature to the heating jacket heater strip in the controller 6 under controller 6 effects.Quit work when being lower than target temperature, heating and the collaborative work of dispelling the heat realize being heated the fast constant temperature of vessel.
