Abstract
The utility model discloses a zinc pot thermocouple, comprising a sheathed thermocouple, an inner sleeve, an outer sleeve, and an adapter sleeve. The inner sleeve is embedded in the outer sleeve. Ends of the inner sleeve and the outer sleeve are closed, and the other ends are open. An end of the adapter sleeve is sleeved on an outer wall of an opening end of the outer sleeve, and the adapter sleeve and the outer wall are connected in a sealing manner. The sheathed thermocouple inserts into an inner cavity of the inner sleeve from the other end of the adapter sleeve. The outer wall of the outer sleeve is provided with a metal ceramic coating. The inner sleeve is made of thermally conductive and insulating elastic rubber. The zinc pot thermocouple is provided with the anticorrosive metal ceramic coating on the outer wall of the outer sleeve, the inner sleeve is made of thermally conductive and insulating elastic rubber, absorbing impact on the thermocouple sleeve, thereby effectively prolonging service life of the thermocouple, and meanwhile manufacturing precision requirements for internal and external are reduce, and cost is saved.
Description
Technical field
The utility model relates to temperature survey utensil field, is specifically related to a kind of thermopair for zinc pot thermometric.
Background technology
In zinc pot production technology, adopt thermocouple measurement aluminium zinc solution temperature to control the heating of zinc pot as controlling parameter, armoured thermocouple is immersed in corrosion and the vibration influence that is subject to aluminium zinc solution in zinc pot solution, only have several days serviceable life, the operating cost of zinc pot is high, and affects the control of zinc pot temperature; For the corrosive problem of aluminium zinc solution; there is the measure of installing corundum or silit protective casing at thermopair outer wall additional that adopts; between protective casing and armoured thermocouple, easily there is gap; can form on the one hand empty resistance; reduce the sensitivity of thermopair; the control effect that affects zinc pot, the shock resistance of corundum or silit is poor on the other hand, easily breaks.Prior art has by being controlled at armoured thermocouple close-fitting ceramic coat pipe and stainless steel inner sleeve is set outward, ceramic coat pipe can solve the etching problem of aluminium zinc solution, and ceramic coat pipe and stainless steel inner sleeve closely cooperate, avoid occurring gap, can solve empty resistance problem, guarantee the sensitivity of thermocouple measurement, this thermopair needs Precision Machining outer tube and inner sleeve, improved the manufacturing cost of thermopair, and outer tube and inner sleeve are rigid, cannot absorb the impact of aluminium zinc solution vibrations to thermopair, on still there is certain impact the serviceable life of thermopair.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of zinc pot thermopair, ceramic coat pipe and the stainless steel inner sleeve that can solve existing zinc pot thermopair closely cooperate to solve the problem that occurs gap between the corrosion of aluminium zinc solution and inside and outside sleeve pipe, cause the manufacturing cost of thermopair to increase, and the inside and outside sleeve pipe of rigidity cannot impact-absorbing, affect the thermopair problem in serviceable life.
The utility model is achieved through the following technical solutions:
A kind of zinc pot thermopair, comprise armoured thermocouple, inner sleeve, outer tube, joint sleeve, described inner sleeve is nested in outer tube, one end sealing of described inner sleeve and outer tube, other end opening, described joint sleeve one end is enclosed within outer tube openend outer wall and is tightly connected, described armoured thermocouple inserts inner sleeve inner chamber from the other end of joint sleeve, and described outer tube outer wall is provided with metal-cermic coating, and described inner sleeve is made by heat conductive insulating elastic caoutchouc.
Further improvement of the utility model scheme is that the metallic ceramics of making described coating is oxide base cermet.
Further improvement of the utility model scheme is, described inner sleeve and outer tube and armoured thermocouple interference fit.
Further improvement of the utility model scheme is that described outer tube is stainless steel.
The utility model advantage is compared with prior art:
Sleeve outer wall arranges etch-proof metal-cermic coating outside, with heat conductive insulating elastic caoutchouc, makes inner sleeve, absorbs the impact to thermocouple sheath, effectively extends the serviceable life of thermopair, has also reduced inside and outside manufacturing accuracy requirement simultaneously, cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
