Description
The technical field is as follows:
the utility model relates to a level gauge, especially a stifled intelligent teletransmission warning level gauge is prevented frostbite by heating furnace.
Background art:
the oil field development is designed to use a water jacket type heating furnace at the initial stage to meet the special requirements of the oil field, and the heating furnace used in each oil production station mainly completes the work of crude oil heating, circulation, water mixing heating, in-station heating and the like.
The level gauge of one of the three important accessories of the heating furnace is used for reflecting the use condition of a heating medium in the furnace body, the existing level gauge is a glass tube level gauge which is mostly adopted to display the height of the liquid level in the heating furnace shell, and during the production operation in winter, the phenomenon that the glass tube is frozen, blocked, damaged, exploded and the like is easily caused because the level gauge is influenced by external low temperature.
The water jacket heating furnace used at present in each oil production station has two methods for controlling and displaying the liquid level in the furnace body, firstly, a visual glass tube liquid level meter is used, the condition that a heating medium in the furnace body of the heating furnace is lost is determined by manual inspection, water supplement is completed, and a common glass tube liquid level meter is possibly frozen under the condition of low temperature in winter, so that the liquid level warning effect cannot be achieved, and potential safety hazards are generated. And secondly, the magnetic turning plate liquid level instrument is used, so that the problem of freezing prevention in winter can be solved, the phenomena of magnetic turning plate jamming, magnetic fading and the like often occur, and the monitored liquid level cannot be accurately displayed in time.
The control and display method of the liquid level in the furnace body of the existing water jacket furnace is only by taking a visible glass tube liquid level meter as a means. During production in winter, the high liquid level in the heating furnace directly influences the heat efficiency of the heating furnace, the gas consumption is high, the temperature raising is slow, the working requirement is difficult to achieve, the low liquid level in the furnace body can cause the main fire barrel and the auxiliary fire barrel to be exposed outside, the dry combustion and deformation are easy, the accident potential exists, and the normal operation can be ensured only by timely finding. Because the liquid level meter is influenced by a low-temperature environment, the phenomena of freezing blockage, damage, burst and the like of the glass tube are easily caused. In winter, the liquid in the glass tube can be released only by opening the down-flow valve, and the liquid level in the furnace body of the heating furnace is checked, so that the inspection is inconvenient to manage and is not applicable.
The invention content is as follows:
the utility model aims at providing a stifled intelligent teletransmission warning level gauge is prevented frostbite to the defect that exists in the above-mentioned technique by the heating furnace.
The purpose of the utility model is realized like this: comprises a control box, an upper flange, a lower flange, a shell, a thermal resistor, a glass tube, a heating belt, a threading tube, a low-level alarm, a high-level alarm and a blow-off valve, the intelligent anti-freezing remote transmission alarm liquid level meter is characterized in that an upper flange and a lower flange are respectively arranged on the side faces of the upper end and the lower end of a shell, a wire outlet is formed in the upper end face of the shell, a sewage discharge valve is arranged on the lower end face of the shell, a glass tube and a temperature sensor are mounted inside the shell, a threading tube is mounted in the glass tube, a high-level alarm is arranged at the upper end of the threading tube, a low-level alarm is arranged at the lower end of the threading tube, a heating belt is wound outside the glass tube, an observation window is arranged on the shell, a control box is connected with the high-level alarm, the low-level alarm, the temperature sensor and the heating belt, a first liquid-through valve is arranged between the upper flange and the shell, a second liquid-through valve is arranged between the lower flange and the shell, and an audible and visual alarm is arranged on the control box, so that the intelligent anti-freezing remote transmission alarm liquid level meter is integrally formed.
The utility model has the advantages that: the liquid level meter comprises a temperature control system and a liquid level alarm system. The temperature control system is suitable for being opened in winter, prevents the problems of freezing, freezing and blocking of the liquid level meter, leakage of the valve and the like, can be closed in other seasons, and saves energy. The liquid level alarm system monitors and alarms instantly. The liquid level meter is provided with a liquid through valve at the upstream and downstream ports, and the liquid through valve is automatically closed under the condition that the liquid level meter is accidentally damaged (frozen, blocked and burst) during the production of the glass tube in winter, so that the liquid in the furnace body is prevented from being lost and accidents are avoided.
