Abstract
The utility model discloses a practical electric heating funnel, which solves the problem that an existing funnel is deficient, and is characterized in that a resistance wire conductor is encircled around the inner layer of a double-layer iron-made heat preservation funnel, the resistance wire conductor is led out through a iron-made funnel handle and is connected with a handle socket hole arranged at the external end of the iron-made funnel handle, and crystals can be extracted effectively during heating by using the resistance wire conductor. In addition, the practical electric heating funnel is also provided with another resistance wire conductor, which is provided with a high, medium and low temperature control switch which can control the temperature of the funnel during operation, so that required temperature can be provided at different time. When the funnel is heated, the end with a socket head is inserted in the other end with the handle socket hole. After the power is switched on, a glass cone-shaped funnel is put in the iron-made heat prevention funnel. In this way, the electric heating funnel can be operated normally. The practical electric heating funnel has simple structural design, is convenient to operate, is safe and practical, has low manufacturing cost, and is easy to produce.
Description
Affiliated technical field
The utility model relates to a kind of chemistry, industry, and the process equipment of crystallization and purification especially extracts a kind of device of medicine in the scientific research field at chemical laboratory.
Background technology
In the required crystallization and purification technology of departments such as chemical laboratory, chemical industry, scientific research, the heated funnel of existing use generally is the handspike that is heated to be housed in the middle and lower part of funnel directly heat, the heated funnel of this structure mainly will have four defectives: the one, and because of organic solution steam is avoided naked light most, dangerous with fire at chemical laboratory.The 2nd, might cause scald because of carelessness in operation, make it not too safe.The 3rd, heat time heating time, long funnel was heated inhomogeneously, influenced the purification quality.The 4th, the handle that is heated is for a long time at the naked light of alcolhol burner directly under the heating, is that the handspike is rotten easily, sealing-off, very inconvenience, more seriously in experimental implementation is carried out because the cause of the handspike is that experimental work is affected.The purpose of this utility model provides that a kind of easy to use, safe, simple in structure, firing rate is fast, funnel is heated evenly, controls conveniently, builds a kind of better filtercondition.
Summary of the invention
The purpose of patent of the present invention provide a kind of easy to use, safe, simple in structure, the firing rate funnel is heated evenly, control conveniently, builds a kind of better filtercondition.
The design's technical scheme is:
The design comprises the glass conical funnel, iron hot funnel internal layer, iron hot funnel skin, iron funnel handle, socket head, high, medium and low temperature control switch, handle socket hole, resistance wire lead and iron hot funnel.Around a resistance wire lead, and connect with high, medium and low temperature control switch around the iron hot funnel internal layer, socket head is arranged in the handle socket hole during heating.Be provided with two-layer iron hot funnel internal layer all around around a resistance wire lead, and extract with the handle socket hole that is provided with in iron funnel handle outer end by iron funnel hadle resistance wire lead and to couple together, use the resistance wire lead in the process of heating, to extract crystal efficiently.Also have one in addition and be provided with high, medium and low temperature control switch, can in carrying out, operation control the temperature of funnel, so that provide required temperature at different time, when heated funnel, one end of socket head is inserted the handle socket hole other end, again the glass conical funnel is put into iron hot funnel after connecting power supply, so just can operate normally.
The beneficial effects of the utility model are: this is simple in structure, easy to operate, safe and practical, cost is low easily produces.Be to make that funnel is heated evenly, firing rate is saved the operating time soon.The extraction crystal of efficiently guaranteeing the quality.The gauge tap of a high, medium and low temperature is set in the middle of lead in addition, makes easy to installation and maintenance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified
(part shown in the numeral is all unified among each figure)
Fig. 1 is the design's a overall schematic
Among the figure: 1. glass conical funnel, 2. iron hot funnel internal layer, 3. iron hot funnel skin, 4. iron funnel handle, 5. socket head, 6. high, medium and low temperature control switch, 7. handle socket hole, 8. resistance wire lead, 9. iron hot funnel.
The specific embodiment
In Fig. 1, around the iron hot funnel internal layer 2 that is provided with two-layer iron hot funnel 9 around a resistance wire lead 8, and by iron funnel handle 4 resistance wire lead 8 is extracted and couple together in the handle socket hole, iron funnel handle 4 outer end 7 of iron hot funnel 9, use resistance wire lead 8 in the process of heating, to extract crystal efficiently.Also have one in addition and be provided with high, medium and low temperature control switch 6, can in carrying out, operation control the temperature of iron hot funnel 9, so that provide required temperature at different time, when the iron hot funnel 9 of heating, socket head 5 one ends are inserted handle socket hole 7, the other end is put into iron hot funnel 9 to glass conical funnel 1 after connecting power supply again, make like this funnel be heated more even, firing rate is faster and save the operating time.The extraction crystal of efficiently guaranteeing the quality so just can be operated normally.
