Abstract

The utility model relates to an electric-heating heat-filtering funnel which is characterized in that all around a conic funnel (1), a sealed heating space is welded up by an outer liner (3), an annular panel (4) and an annular soleplate (6); the column handle of the funnel (1) is provided with an electric heating element (2); one side on the lower part of the outer liner (3) is provided with the power socket (7) of the electric heating element (2), and the other side is provided with decoration holes on which a seal washer and a cover plate (9) are fixed; the surface of the outer liner (3) is coated with a heat-insulating layer. The utility model overcomes the defects of the existing heat-filtering funnel, such as open firing, failure to filter hot organic solutions, slow heat conduction, uneven heating, an easily burned off heated handle, etc., and can be used for purification process with recrystallization in medicine, chemical industry, scientific research and other fields.

Description

Electric-heating heat-filtering funnel

The utility model relates to a kind of equipment that is used for medicine, chemistry, scientific research field recrystallization purifying process, is a kind of electrothermal heat filter funnel specifically.

In medical industry, chemical reagent industry, chemical experiment, in the recrystallization purifying process of departments such as scientific research, the heat of existing use filter funnel generally is to be welded with the handle that is heated in the funnel bottom, adopts alcolhol burner that the handle that is heated is directly heated.The heat filter funnel of this structure mainly contains three defectives: the one, and because of organic vapor is avoided naked light most, therefore this device should not be done the heat filter of inflammable organic solution; The 2nd, this structure because of the water convection current is incomplete, has the dead angle when heating, and it is slow to conduct heat, and makes heat filter funnel be heated inhomogeneous; The 3rd, the handle that is heated is for a long time at the naked light of alcolhol burner directly under the barbecue, sealing-off easily, and the service life of therefore this heat filter funnel is short.

The purpose of this invention is to provide a kind of simple in structurely, the heat transfer rate piece is heated evenly, without the electrothermal heat filter funnel of naked light heating.

The purpose of this utility model is achieved in that on the cylindric handle of the Dipper of 60 degree conical funnels (1), design has heating (2), design has shape overcoat (3) similarly around funnel (1), upper end between funnel (1) and the overcoat (3) is welded with ring-type panel (4), panel (4) is gone up design two spill water injection holes (5), lower end between funnel (1) and the overcoat (3) is welded with annular base plate (6), the interior circular diameter of this annular base plate equates with the cylindrical handle external diameter of funnel (1) and is welded as a whole, the one side design of overcoat (3) has the electric input socket (7) of heating (2), the carriage (8) of holding heating (2) is installed in the inside of overcoat (3) opposite side, have a finishing hole in the outside of overcoat (3) opposite side, finishing has been screwed seal washer and cover plate (9) on the hole; The surface of overcoat (3) scribbles one deck insulation lacquer or other insulation materials.

Advantage of the present utility model: 1. simple in structure, make easily long service life; 2 funnels adopt double-decker, and the heating space sealing with the heating heating, does not have naked light again, are applicable to the organic solution heat filter that various solution are particularly inflammable; 3. this funnel heating surface area is big and even, no dead angle, and the thermal source cost is low; 4. because of overcoat (3) one sides have the finishing hole, be screwed seal washer and cover plate on the hole, made easy to installation and maintenance.

Introduce an embodiment below in conjunction with accompanying drawing:

Fig. 1 partly cuts open schematic diagram for of the present utility model facing;

Fig. 2 is a vertical view of the present utility model; Fig. 3 is a upward view of the present utility model; Fig. 4 is a right side view of the present utility model; Fig. 5 is a left side view of the present utility model.

With reference to accompanying drawing, with the thick metallic plate of 0.5mm.The conical funnel (1) at 60 degree angles is made in weldering and greater than the conical overcoat (3) of funnel (1), a side has the supply socket hole in the bottom of overcoat (3), and opposite side has the finishing hole; Tailor with the thick metallic plate of 0.5mm again and circularize panel (4) and base plate (6).The interior external diameter of annular panel (4) respectively with the equal diameters of funnel inlet and outer set upper side, panel (4) has two spill water injection holes (5) in the diametric(al) design, and the interior external diameter of annular bottom plate (6) equates with the outlet of funnel (1) and the lower end diameter of overcoat (3) respectively; Then with panel (4), base plate (6), be welded on the top and bottom between funnel (1) and the overcoat (3) respectively, make and become the integral body that the heated sealed space is arranged between funnel and the overcoat, on the cylindrical handle of funnel (1), install electric heater (2) at last, the input of electric heater (2) is connected in the supply socket (7) of overcoat (3) one sides, the other end of heater (2) is supporting with the carriage (8) that is fixed on overcoat (4) inner face, by screw seal washer and cover plate (9) are fixed on the finishing hole of overcoat (3), be coated with last layer insulation lacquer at last on the surface of overcoat (3), to make full use of heat energy.So far electrothermal heat filter funnel just can formally come into operation.

Claims

1, a kind of electrothermal heat filter funnel, comprise funnel (1), overcoat (3), heating (2), panel (4), base plate (6), supply socket (7), the carriage (8) of heating (2) and cover plate (9), it is characterized in that: design has heating (2) on the cylindrical handle of funnel (1), and funnel (1) is welded with annular panel (4) with the upper end of overcoat (3), and the lower end is welded with annular bottom plate (6), form the heating space of sealing between funnel (1) and the overcoat (3), overcoat (3) surface scribbles the insulation lacquer.

2, electrothermal heat filter funnel according to claim 1, it is characterized in that: a side of overcoat (3) bottom is equipped with the supply socket (7) of heating (2), and opposite side has the finishing hole, is fixed with seal washer and cover plate (9) by screw on the hole; The inner face of overcoat (3) bottom is fixed with the carriage (8) that supports heating (2).
