Description
Technical field
The utility model belongs to disappear and boils apparatus field, is specifically related to a kind of efficient chemical analysis and for measuring disappearing of COD, boils equipment in detecting.
Background technology
COD is one of conventional five indices of water-quality determination, be also general water quality detection must survey index.The determination step of water sample COD is not difficult, but compared with time-consuming, reason is that Digestion time is longer, generally more than 2h, and common disappearing to boil equipment be generally with heating by electric cooker, and fixing condenser pipe, once can only disappear and boil one to two water sample, efficiency is very low, also needs equipment to disassemble after being finished, and work efficiency is very low.
Summary of the invention
The purpose of this utility model is: in detecting for chemical analysis, COD disposable can only the disappearing while boiling that disappear boiled the problem of one or two water sample, provide a kind of disposable disappearing to boil the equipment of a plurality of water samples, it is simple in structure, equipment is fixed, without disassembling, be easy to apply in laboratory.
Solution of the present utility model is: on support, sequence interval is installed a series of heating plates, each heating plate top hangs a set of reflux condensing tube by support, head and the tail between each adjacent condenser pipe are imported and exported and are communicated with according to this with proofed sleeve, the water inlet of initial workpiece condenser pipe connects water tap with rubber tube, the water delivering orifice of end part condenser pipe connects another rubber tube, and heating plate is connected with contact type voltage regulator by electric wire.
The suspension height of described condenser pipe is that bottom just extends to disappear and boils in triangular flask, and the range of regulation of contact type voltage regulator is 0～250V, and heating plate is circular mica heating plate.
Corresponding each heating plate is provided with independently switch on the crossbeam of support, disappearing while boiling the water sample of negligible amounts, can close no switch, to this part heating plate for electrical heating, thereby save the energy.
The beneficial effects of the utility model are:
1, the utility model is installed many cover facilities on a support, once can disappear and boil several to dozens of water samples, and having improved disappears boils efficiency.
2, in the utility model, between adjacent different row supports, switch is installed, disappears while boiling the water sample of negligible amounts, can closing switch, economize on resources, stop unnecessary energy dissipation.
3, the utility model is fixed equipment, without disassembling, before having solved, disappears and boils the problem of occasional combination equipment.
4, the utility model utilizes contact type voltage regulator power supply, by regulation voltage, controls temperature, can guarantee that COD completely disappears and boils.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, support, 2, water inlet pipe, 3, rising pipe, 4, rubber tube, 5, condenser pipe, 6, heating plate, 7, switch, 8, contact type voltage regulator.
Embodiment
As shown in Figure 1, equipment adopts frame-type aluminium alloy post, on support 1, sequence interval has been installed a series of circular mica heating plates 6, the backing positions suspender of each heating plate 6 top, the a set of reflux condensing tube 5 of corresponding suspension, head and the tail between each adjacent condenser pipe 5 are imported and exported and are communicated with according to this with proofed sleeve, the water inlet of the initial workpiece condenser pipe 5 of arranging is received water tap with rubber water inlet pipe 2, the water delivering orifice of the last part condenser pipe 5 of arranging connects another rubber rising pipe 3, heating plate 6 is connected with contact type voltage regulator 8 by electric wire, by pressure regulator, in the scope of 0～250V, carry out pressure regulation.Each 6 pairs of circular mica heating plate should have independently switch, is arranged on the crossbeam of support 1, disappearing while boiling the water sample of negligible amounts, can close no heating plate 6, saves the energy.
In use, first the ground triangular flask of putting sample well is placed on circular mica heating plate, the corresponding condenser pipe lower end mouth of pipe is placed in triangular flask.By water inlet connecting tap, water delivering orifice is put into water-accepting tank, regulates flow rate of water flow, after water delivering orifice water outlet evenly, open pressure regulator to 250V, in triangular flask, after solution boiling, regulate pressure regulator to 175V, and start timing, after disappearing and boiling 175 minutes, close pressure regulator to 0, in triangular flask, solution is closed condenser pipe water inlet water swivel after slowly cooling, and rinse condenser pipe from top to bottom with a small amount of distilled water, disappearing, it is complete to boil.
Claims (3)
1. a COD efficiently disappears and boils equipment, it is characterized in that: on support, sequence interval is installed a series of heating plates, each heating plate top hangs a set of reflux condensing tube by support, head and the tail between each adjacent condenser pipe are imported and exported and are communicated with according to this with proofed sleeve, the water inlet of initial workpiece condenser pipe connects water tap with rubber tube, the water delivering orifice of end part condenser pipe connects another rubber tube, and heating plate is connected with contact type voltage regulator by electric wire.
2. COD according to claim 1 efficiently disappears and boils equipment, it is characterized in that: the suspension height of condenser pipe is that bottom just extends to disappear and boils in triangular flask, and the range of regulation of contact type voltage regulator is 0～250V, and heating plate is circular mica heating plate.
