Abstract
The utility model discloses a material level switch applicable to high-temperature and high-pressure materials. The material level switch comprises a sensor, a transmitter, an installing base and a material level probe, wherein the material level probe comprises a protective jacket, an insulating sleeve, a probe body and a guard plate, the protective jacket is fixedly connected with the installing base, the insulating sleeve is sleeved with the protective jacket, the probe body is sleeved with the insulating sleeve, the front end of the probe body extends out of the insulating sleeve, the tail portion of the guard plate is fixedly connected with the protective jacket, the front end of the guard plate extends to the position above the probe body, the probe body is covered with the guard plate. According to the material level switch applicable to the high-temperature and high-pressure materials, due to the facts that the guard plate is fixedly arranged on the protective jacket, and the probe body is covered with the guard plate, the phenomenon that a probe is smashed when materials are thrown in can be effectively avoided, the service life of the material level probe is prolonged, measuring accuracy of the material level probe is improved, the frequency of maintenance is reduced, and the environmental adaptability of the material level probe is improved.
Description
Technical field
The control measurement technical field that the utility model relates to, particularly relates to a kind of stuff level switch that is applicable to high temperature, high pressure.
Background technology
Level gauging is that industrial enterprise is as mine, electric power, building materials, the normal operating important parameter of petrochemical industry, storage equipment is generally by storage tank, charging aperture, drain hole, the compositions such as dispensing valve, traditional metering system is the measuring method of employing time blowing, all dispensing valves are opened the material in emptying hopper one time at set intervals, be generally solid or liquid etc., due to many hoppers simultaneously blowings can cause excessive load to the conveyer below storage tank, cause conveyer to damage, and the material quantity difference accumulating due to each hopper, some hoppers even can cause sky blowing, cause the inaccurate of level gauging, cause the waste of resource, traditional level-sensing device is at high temperature, high pressure, when adhering to by force, measuring under thump weares and teares by force, dust is large environment, and probe is very easily received damage, and serviceable life is short, safeguards more difficultly, and when especially lump material falls, above-mentioned situation is particularly outstanding.
Utility model content
The purpose of this utility model is for the technological deficiency existing in prior art, and a kind of high temperature stuff level switch that is applicable to the material level of high temperature, high pressure and can effectively improves impact resistance is provided.
For realizing the technical scheme that the purpose of this utility model adopts be:
A kind of stuff level switch that is applicable to high temperature, high pressure, comprise sensor, transmitter, mount pad, and material level probe, described material level probe comprises the sheath being fixedly connected with mount pad, be sleeved on insulating sleeve in sheath and be sleeved in described insulating sleeve and leading section extends the probe outside insulating sleeve, and afterbody is fixedly connected with front end and extends to above described probe and the backplate of being screened with described sheath.
Described sheath and probe are stainless steel, and described insulating sleeve is made up of pottery.
Described backplate is made up of carbon steel or manganese steel plate or spring steel, and different materials embodies different features, but can play the effect of protection, as, laminated spring can be dissolved impact in the deformation not affecting under probe prerequisite by himself.
Described backplate is L-shaped.
Described backplate afterbody welds or is connected by abutment ring with described sheath.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is fixedly installed a backplate on sheath, and backplate covers described probe, can effectively prevent that material from losing the fashionable probe that smashes, and improves serviceable life and the measuring accuracy of probe, reduces and safeguards, improves its adaptability to environment.
Brief description of the drawings
Figure 1 shows that structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the high temperature that is applicable to of the present utility model, stuff level switch under hyperbaric environment is typically applied in the furnace of calcium carbide hopper material level of Coal Chemical Industry industry, the grate-cooler hopper material level of building material industry, the measurement of coking industry tar ship liquid level, described stuff level switch comprises sensor 2, transmitter 1, mount pad 3, and material level probe 4, in the instrument chamber of described sensor setting on mount pad and by cable, be connected with described transducer signal, sensor is by the voltage of the inner material level probe of sensing, the signal intensities such as electric capacity and pass to transmitter decode process carry out material level detection to feed back to control system.Wherein said material level probe comprises the stainless steel sheath being fixedly connected with mount pad, be sleeved on insulating sleeve that the pottery in sheath makes and be sleeved in described insulating sleeve and leading section extends the stainless steel probe outside insulating sleeve, and afterbody is fixedly connected with front end and extends to above described probe and the backplate 5 of being screened with described sheath.Specifically, described mount pad and the hopper of grate-cooler 6 sidewalls are threaded connection, described sheath and mount pad are threaded connection, described insulating sleeve and described sheath are by high temperature bond glue bond, described probe is fixedly connected with described insulating sleeve by high temperature bond glue, the length that described probe stretches out insulating sleeve is had nothing in common with each other product specification or applying working condition, the leading section of certainly, described insulating sleeve also extended described sheath one segment distance to improve bulk strength and assembling capacity.
The utility model is fixedly installed a backplate on sheath, and backplate covers described probe, can effectively prevent that material from losing the fashionable probe that smashes, and improves serviceable life and the measuring accuracy of probe, reduces and safeguards, improves its adaptability to environment.
Specifically, described backplate is made up of carbon steel, in general, be positioned at probe top and keep preset space length for realizing backplate, described backplate is L-shaped, its afterbody is with the welding of described sheath or be connected by abutment ring, and described abutment ring connects and refers at backplate afterbody and be integrally formed or be fixedly connected with an opposite opened abutment ring that can be set on sheath, realizes being fixedly connected with backplate and sheath by the openend of locking opposite opened abutment ring.Wherein, for strengthening the intensity of backplate, enhancing cant beam also can be set between described backplate and sheath, further, the curved or axial centre in described backplate cross section upwards heave design with prevent material thereon accumulation affects measure.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
