Use coating film quartz capsule heating device on environmental protection water quality analyzer ware, including quartz glass tube, quartz glass tube's both ends all are provided with the collecting ring, are provided with extraction electrode on the collecting ring, and the key is: the transmission unthreaded hole that has the symmetry to set up on quartz glass tube's lateral surface, quartz glass tube's surface all is provided with resistive layer the region except that transmission unthreaded hole position with below the collecting ring, and resistive layer's both ends are connected with the collecting ring that is close to this end respectively. With the electrical heating with the direct surface attached to quartz glass tube of resistive layer form, resistive layer has that hot conversion efficiency is high, the power attenuation volume is little, the conduction is fast, save time, control accuracy is high, long service life's advantage for hot digestion instrument heat time is short, and heating power is little, and hot coupling efficiency is high, and it is fast to heat up, and the heating is even, and the temperature fluctuations scope is little, has realized the heating of low -voltage safety.
Description
Technical field
The utility model belongs to heating device technology area, relates to the plated film quartz ampoule heater be applied on environmental protection analytical instrument of water quality.
Background technology
In integrated environmental protection analytical instrument of water quality, common method of carrying out heating for solution in glass tube heats with heating wire winding outside quartz glass tube, the degree of coupling between this heating means heater element and quartz glass tube is very low, and heat dissipation is large, and the heat efficiency is low, conducting effect is poor, thermal inertia is large, and hysteresis quality is large, and control precision is poor, energy ezpenditure is many, and thermal radiation is many towards periphery.Therefore, the heater that a kind of heat efficiency is high, conduction of velocity is fast, control precision is high is badly in need of.
Summary of the invention
The utility model is in order to overcome the defect of prior art, devise the plated film quartz ampoule heater be applied on environmental protection analytical instrument of water quality, electric heating is attached directly to the outer surface of quartz glass tube with resistive layer form, form high efficiency direct thermal coupling, short for heating time to content digestion process, consumed power is little, and heat transference efficiency is high, quick heating, homogeneous heating, control precision is high, and temperature fluctuation range is little, and embodiment have employed safety low-voltage heating.
The concrete technical scheme that the utility model is taked is: be applied in the plated film quartz ampoule heater on environmental protection analytical instrument of water quality, comprise quartz glass tube, the two ends of quartz glass tube are all provided with collector ring, collector ring is provided with extraction electrode, key is: on the lateral surface of quartz glass tube, have symmetrically arranged transmission unthreaded hole, the outer surface of quartz glass tube is except transmission unthreaded hole position and collector ring are to be all provided with resistive layer except lower area, and the two ends of resistive layer are connected with the collector ring near this end respectively.
Described resistive layer adopts the metal ion of nano thickness to form electrically heated resistant heat generating layer.
Described extraction electrode is copper clamp.
The beneficial effects of the utility model are: outer surface electric heating being attached directly to quartz glass tube with resistive layer form, resistive layer has that thermal conversion efficiency is high, power attenuation amount is little, conduction is fast, save time, control precision is high, the advantage of long service life, make hot digestion instrument thermal coupling efficiency high, heating time is short, dissipation power is little, quick heating, homogeneous heating, temperature fluctuation range is little, achieves low voltage safety heating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1 represents quartz glass tube, and 2 represent collector ring, and 3 represent extraction electrode, and 4 represent transmission unthreaded hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Specific embodiment, as shown in Figure 1, be applied in the plated film quartz ampoule heater on environmental protection analytical instrument of water quality, comprise quartz glass tube 1, the size of quartz glass tube 1 adjusts accordingly with purposes difference, the two ends of quartz glass tube 1 are all provided with collector ring 2, collector ring 2 is provided with extraction electrode 3, extraction electrode 3 is copper clamp, the lateral surface of quartz glass tube 1 has symmetrically arranged transmission unthreaded hole 4, the shape of transmission unthreaded hole 4 is strip, or it is circular, or other shape, to meet the light transmittance of optical measurement, transmitting illuminant and receiver can detect photosignal by transmission unthreaded hole 4.The outer surface of quartz glass tube 1 is except transmission unthreaded hole 4 position and collector ring 2 are to be all provided with resistive layer except lower area, the two ends of resistive layer are connected with the collector ring 2 near this end respectively, make collector ring 2 cover Formation Depth on resistive layer to merge, resistive layer adopts the metal ion of nano thickness to form electrically heated resistant heat generating layer, concrete thickness is changed accordingly according to power difference, it is high that resistive layer has thermal conversion efficiency, power attenuation amount is little, conduction is fast, save time, control precision is high, the advantage of long service life, make hot digestion instrument short for heating time, heating power is little, thermal coupling efficiency is high, quick heating, homogeneous heating, temperature fluctuation range is little, achieve low voltage safety heating, there is extraordinary fail safe and isolation.Resistive layer is close to quartz glass tube 1 surface, form high efficiency thermal coupling, variations in temperature accurately can be obtained, for temperature controls to provide SERVO CONTROL accurately, stablize when control system before temperature approaches design temperature threshold value is converted to duty ratio heating and temperaturel, eliminate temperature overshot and fluctuation.
