Abstract
The utility model relates to an oxygen probe protector which comprises a protecting tube and a mounting flange. One end of the protecting tube is open and the other end is connected with the mounting flange; a detection hole is arranged on the surface of the protecting tube; a filter can be installed at the open end of the protecting tube; and the protecting tube is made of high-temperature alloy or ceramic material. The protecting tube of the protector wraps a direct insert type zirconia oxygen sensor, and by making use of the high temperature resistance and anti-corrosion capacity of the protecting tube, the oxygen sensor is protected against damages from ashes and dust contained in the high-temperature atmosphere in the furnace. The detection hole is arranged at the surface of the protecting tube, thus ensuring the reaction speed of the zirconia oxygen sensor. The oxygen probe protector can effectively prolong the service life of the zirconia oxygen probe.
Description
Technical field
The utility model relates to a kind of oxygen probe protector.
Background technology
Advantages such as direct insertion zirconium oxide-oxygen probe is because simple in structure, and the response time is short, and measurement range is wide, and serviceability temperature is wide, and is reliable, easy for installation, and maintenance is little, the residual oxygen that is widely used in flue or the burner hearth by various industrial heating furnaces detects.But when being used for high temperature electric stove hearths such as pottery, cement kiln, Industrial Boiler, industrial heating furnace, industrial heat-treatment furnace, laboratory equipment and detecting, residual sulfur compound containing in the burner hearth in high-temperature dust and the atmosphere makes a big impact to the normal use of oxygen probe, and the air-flow that chimney meatus draught fan forms can aggravate damage, even can cause the inefficacy of oxygen probe and can't use.The usable range of having limited to zirconium oxide-oxygen probe so also can cause the oxygen probe lost of life in use.
Summary of the invention
The purpose of this utility model is in order to overcome problem and the defective that above-mentioned existing direct insertion zirconium oxide-oxygen probe exists; a kind of oxygen probe protector is provided; the oxygen probe protector does not change this body structure of oxygen probe and the outside connecting interface of installing, and directly is installed at supporting use on the oxygen probe of standard series.
The technical solution of the utility model is:
The oxygen probe protector is made up of protection tube, mounting flange, it is characterized in that: protection tube one end opening, the other end links to each other with mounting flange, and has the detection hole on the protection tube surface.Protection tube adopts high temperature alloy or ceramic material to form.Can also filtrator be installed at protection tube opening one end.
During installation, direct insertion zirconia probe is inserted into earlier in the protector, is fixed together, then both are inserted in flue or the burner hearth together by web member and oxygen probe protector.
The beneficial effects of the utility model: the protection tube of oxygen probe protector is wrapped in direct insertion Zirconium oxide oxygen sensor wherein; utilize the resistance to elevated temperatures and the resistance to corrosion of protection tube, protection lambda sensor itself is not subjected to the ashes that comprise in the furnace high-temperature atmosphere and the infringement of dust.The protection tube surface has detects the hole, guarantees the reaction velocity of Zirconium oxide oxygen sensor.The oxygen probe protector can effectively prolong the serviceable life of zirconium oxide-oxygen probe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the synoptic diagram of installing and using of the present utility model.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model is made up of protection tube 1, filtrator 2, mounting flange 3, protection tube 1 one end openings; at protection tube 1 opening one end filtrator 2 is installed; can certainly uneasy fixed filter, the other end links to each other with mounting flange 3, and offers on protection tube 1 surface and to detect hole 4.Protection tube 1 adopts the alundum (Al ceramic material to form.
During installation; direct insertion zirconia probe 5 is inserted into earlier in the protection tube 1; by web member 6 direct insertion zirconia probe and high-temperature oxydation zirconium oxygen probe protector are fixed together, then both are inserted in flue or the burner hearth together, be fixed on the wall of flue or burner hearth by flange 3 again.
The protection tube of this protector is wrapped in direct insertion Zirconium oxide oxygen sensor wherein, utilizes the resistance to elevated temperatures and the resistance to corrosion of protection tube, and protection lambda sensor itself is not subjected to the ashes that comprise in the furnace high-temperature atmosphere and the infringement of dust.The protection tube surface has detects the hole, guarantees the reaction velocity of Zirconium oxide oxygen sensor.The oxygen probe protector can effectively prolong the serviceable life of zirconium oxide-oxygen probe.
