Abstract
The utility model belongs to the technical field of the industrial manufacturing technique and specifically relates to a pre-buried hole mechanism convenient to protection thermocouple, the installation structure comprises a sleeve pipe, sheathed tube one end fixed mounting has the mounting panel, four fixed orificess are installed to the equidistant interval in edge of mounting panel. The utility model discloses increase the pre-buried hole diameter, can adopt the thermocouple that the diameter is thicker to solve because the difficult problem that the drawback of thinner thermocouple brought, changed the mounting panel into by original threaded connection and connect, reduced the outside and rocked the damage that causes the thermocouple, also enable the thermocouple simultaneously and separate with the pre-buried hole, need not direct contact, thereby improve the life of thermocouple greatly.
Description
Technical Field
The utility model relates to an industrial manufacturing technical field especially relates to a pre-buried hole mechanism convenient to protection thermocouple.
Background
The waste incineration power plant is when burning rubbish, will use the burning furnace, one side of burning furnace will set up the buried hole and install the thermocouple, the thermocouple can monitor the temperature in the burning furnace, the internal diameter of the buried hole that uses at present is 25mm, screw thread M20 1.5mm, lead to only using the thermocouple that the diameter is phi 20mm, and buried hole ratio is less, stifled ash is serious, the thermocouple is thinner, bear external force relatively poor, cause the thermocouple easily bad and difficult change, cause the short reason of thermocouple life because the operating mode in the waste incineration power plant furnace is very complicated, flue gas temperature is high in a passageway, contain all kinds of acid gas in the flue gas, the corrosivity is strong, be mingled with a large amount of slag, the ashes, the dust, at the passageway upper portion toward the stove in the injection aqueous ammonia, concentrate etc. The substances are gradually accumulated and coked on the furnace wall and the thermocouple, the bearing capacity of the thermocouple is increased, the alloy thermocouple is difficult to coke and replace, and the silicon carbide thermocouple is easy to break when a coke block falls; in addition, ammonia water and concentrated solution can not be rapidly atomized, and a part of the ammonia water and the concentrated solution can directly fall on the thermocouple body, so that the thermocouple is frequently expanded with heat and contracted with cold, and is broken due to uneven stress; the material in the hearth is complex, and the thermocouple has the characteristic of high-temperature corrosion, so that the thermocouple body is scoured and abraded. Therefore, the pre-buried hole mechanism convenient for protecting the thermocouple is provided.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a pre-buried hole mechanism convenient for protecting a thermocouple.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the design is a pre-buried hole mechanism convenient to protect thermocouple, and comprises a sleeve, sheathed tube one end fixed mounting has the mounting panel, four fixed orificess are installed to the edge of mounting panel equidistant.
Preferably, the outer diameter of the sleeve is 78mm, and the thickness of the sleeve is 6.5 mm.
Preferably, the sum of the thickness of the mounting plate and the length of the sleeve is 400 mm.
Preferably, the inner diameter of the mounting plate is 65mm, and the outer diameter of the mounting plate is 160 mm.
Preferably, the distance between two corresponding fixing holes is 130 mm.
The utility model provides a pair of pre-buried hole mechanism convenient to protection thermocouple, beneficial effect lies in: the utility model discloses increase the pre-buried hole diameter, can adopt the thermocouple that the diameter is thicker to solve because the difficult problem that the drawback of thinner thermocouple brought, changed the mounting panel into by original threaded connection and connect, reduced the outside and rocked the damage that causes the thermocouple, also enable the thermocouple simultaneously and separate with the pre-buried hole, need not direct contact, thereby improve the life of thermocouple greatly.
Drawings
Fig. 1 is a schematic structural view of a pre-buried hole mechanism for conveniently protecting a thermocouple according to the present invention;
fig. 2 is a right side view structural schematic diagram of a pre-buried hole mechanism convenient to protect a thermocouple.
In the figure: mounting panel 1, sleeve pipe 2, fixed orifices 3.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, a pre-buried hole mechanism convenient for protecting a thermocouple comprises a sleeve 2, wherein the outer diameter of the sleeve 2 is 78mm, and the thickness of the sleeve 2 is 6.5mm, so that a thicker thermocouple can be installed, and the sleeve 2 is prevented from being easily burnt.
The one end fixed mounting of sleeve pipe 2 has mounting panel 1, and the thickness of mounting panel 1 and the length sum of sleeve pipe 2 are 400mm, can effectually protect the thermocouple, improve the life of thermocouple, prevent that the thermocouple is impaired.
The internal diameter of mounting panel 1 is 65mm, and the external diameter of mounting panel 1 is 160mm, conveniently installs the thermocouple, reinforcing practicality.
Four fixed orificess 3 are installed to the equidistant interval in edge of mounting panel 1, and the distance between two corresponding fixed orificess 3 is 130mm, conveniently installs the thermocouple, reinforcing practicality.
The working principle is as follows: the sleeve 2 and the incinerator are fixed through welding, the thermocouple penetrates through the mounting plate 1 and the sleeve 2, and the sleeve is fixedly connected with the mounting plate 1 through a flange on the thermocouple.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
