Abstract
The utility model provides an electric heater of a round-bottom flask for chemical experiments. A semi-circular concave pit is arranged in a base, a heat insulation layer, a heating layer and an asbestos pad layer are sequentially arranged in the semi-circular concave pit from inside to outside, a handle is fixedly connected with the base, a sliding plate is arranged at the top of the handle, the sliding plate and the handle are connected into a whole, a sliding sleeve is sleeved on the sliding plate, one end of a cross plate is fixedly connected with the sliding sleeve, the other end of the cross plate is fixedly connected with a sleeve ring, and a butterfly bolt is connected with the sliding sleeve in a threaded mode. According to the electric heater of the round-bottom flask for chemical experiments, the heat insulation layer is arranged between the heating layer and the base, heat loss is prevented, and the asbestos pad layer is arranged on the heating layer and can prevent the round-bottom flask from directly touching the heating layer to cause uneven heating. When the electric heater of the round-bottom flask for chemical experiments is used, the bottom of the round-bottom flask is arranged in the semi-circular concave pit of the base, the sleeve ring is sleeved on a bottle neck of the round-bottom flask and is then descended slowly to the shoulder part of the round-bottom flask, so that the round-bottom flask does not incline. No danger exists in the process of chemical experiments, and the electric heater can be moved anytime by holding the handle by hand.
Description
Technical field
The utility model relates to a kind of chemical experiment with the electric heater of round-bottomed flask, belongs to the electric heater technical field.
Background technology
Round-bottomed flask is all to be heated by alcolhol burner usually in experiment.Although alcolhol burner does not have anything to pollute, some experiment material is responsive to naked light, does not do a good job and can meet accident.With the alcolhol burner heating, alcolhol burner and round-bottomed flask in heating are if mobile all inconvenient in addition.
Summary of the invention
The purpose of this utility model is the problem that exists in order to solve above-mentioned prior art, although namely alcolhol burner does not have anything to pollute, some experiment material is responsive to naked light, does not do a good job and can meet accident.With the alcolhol burner heating, alcolhol burner and round-bottomed flask in heating are if mobile all inconvenient in addition.And then provide a kind of chemical experiment electric heater with round-bottomed flask.
The purpose of this utility model is achieved through the following technical solutions:
a kind of chemical experiment electric heater of round-bottomed flask, comprise: base, zone of heating, the asbestos bed course, handle, slide plate, wing bolt, sliding sleeve, transverse slat, the collar and thermal insulation layer, described base is provided with semicircular recess, be provided with successively from the inside to the outside thermal insulation layer in semicircular recess, zone of heating and asbestos bed course, handle is fixedly connected with described base, the top of handle is provided with slide plate, slide plate and handle are connected as a single entity, sliding sleeve is enclosed within on slide plate, one end of transverse slat is fixedly connected with sliding sleeve, the other end of transverse slat is fixedly connected with the collar, wing bolt is threaded with sliding sleeve.
The utility model is provided with thermal insulation layer between zone of heating and base, prevent heat abstraction, is provided with the asbestos bed course on zone of heating, can prevent round-bottomed flask Direct Contact Heating layer cause be heated irregular.During use, the bottom of round-bottomed flask is sitting in the semicircular recess on base, the collar is enclosed within on the bottleneck of round-bottomed flask, then slowly drops to down the shoulder of round-bottomed flask, and round-bottomed flask can not be tilted.The utility model is simple and practical, and during chemical experiment, safety without dangerous, is held handle and can be moved at any time.
