Abstract

The utility model relates to an auxiliary device of a reactor, in particular to an overflow protecting device of a reactor, comprising a cylinder body, a liquid outlet arranged at the lower side of the cylinder body, a butt guide pipe arranged at the central position of the upper end surface of the cylinder body, an air outlet arranged at the upper end surface of the cylinder body, a cylindrical floating body arranged below the butt guide pipe and an elastic washer used for plugging the lower end port of the butt guide pipe, wherein one end of the butt guide pipe is connected with the overflow port of the reactor, and the other end thereof extends into the cylinder body; and the elastic washer is arranged at the upper end of the cylindrical floating body. The overflow protecting device not only can store the overflowing liquid temporarily, but also can stop the overflowing in a certain range, give feedback and control a feeding device or send out an alarm signal.

Description

The reactor excess flow protection device

Technical field

The utility model relates to a kind of servicing unit of reactor, is specially the discharge protective device of reactor.

Background technology

Reactor is extensively applied to chemical field; present feeding in raw material to reactor; often rule of thumb judge the reinforced time or whether fill it up with by the uninterrupted liquid of must observing in the kettle of the mode of manual oversight; and kettle only is provided with point of observation usually in the part; so overflow phenomena occurs through regular meeting; but because normally poisonous or corrosive chemical liquid in the still, like this liquid of overflow not only can etching apparatus, contaminated environment, also can influence health.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of reactor discharge protective device is provided, can not only keeps in discharge, and can stop overflow within the specific limits, FEEDBACK CONTROL feeding device or send alarm signal.

For solving the problems of the technologies described above, the utility model reactor discharge protective device comprises: simplified, as to be arranged on cylindrical shell downside leakage fluid dram, also comprise the opposing pipe that is located at center, cylindrical shell upper surface, the venthole of offering in the cylindrical shell upper surface, be arranged on the column buoyancy aid under the opposing pipe, be used for the elastic washer of the above-mentioned opposing pipe lower port of shutoff; Wherein, the overfall of described opposing pipe one end coupled reaction still, the other end extends in the cylindrical shell; Described elastic washer is located at the upper surface of column buoyancy aid.

Like this, when the column buoyancy aid was elevated to certain altitude with the overflowing liquid liquid level, the elastic washer on the column buoyancy aid upper surface can block the opposing pipe lower port, forbade that liquid is dirty in the still, and can make formation vacuum in the reactor.

Can be for the elastic washer on the column buoyancy aid over against the opposing pipe lower port, the side of described column buoyancy aid is arranged with two groups of braced wings that limit its swing.

Further improvement of the utility model is: the upper end of described cylinder inboard wall face also is equipped with touch switch, and it touches the upper surface that arm connects the column buoyancy aid.

Described touch switch is the trigger switch of warning device, and links to each other with power supply.

When adopting pump reinforced, described touch switch can be the power cut-out switch of reactor charge pump, links to each other with the dump line of reactor charge pump.

After adopting the aforesaid reaction vessel excess flow protection device, improved the security of operation; And can be in the reinforced time period release portion labour, increase work efficiency; When overflow phenomena takes place when, make that not only liquid that can not trickles in the reactor everywhere, but also can further stop the expansion of overflow scope by warning device or mode such as cut off the electricity supply, avoid the generation of accident.The utility model is simple in structure, reliable, and safe, practical.

Description of drawings

Fig. 1 is a reactor discharge protective device structural representation;

Fig. 2 is user mode figure of the present utility model.

Among the figure: 1, reactor; 2. the reactor protective device that overflows; 3. cylindrical shell; 4. column buoyancy aid; 5. opposing pipe, 6. touch switch; 6-1. shake-up arm; 7. leakage fluid dram, 8. braced wing, 9. elastic washer, 10. venthole.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Embodiment 1, as shown in Figure 1 and Figure 2: reactor excess flow protection device of the present utility model, comprise cylindrical shell 3, leakage fluid dram 7, be located at the opposing pipe 5 of center, simplified 3 upper surface, the venthole of offering in the cylindrical shell upper surface 10 is arranged on the column buoyancy aid 4 under the opposing pipe 5, is used for the elastic washer 9 and the touch switch 6 of above-mentioned opposing pipe 5 lower port of shutoff; Wherein, the overfall of opposing pipe 5 one end coupled reaction stills 1, the other end extends in the cylindrical shell 3; Elastic washer 9 is higher than the upper surface of liquid in container all the time, in case liquid in container leaks outside before warning; Column buoyancy aid 4 limits its swing by braced wing 8 is set around; Touch switch 6 is installed on simplified 3 end faces, and it touches arm 6-1 and links to each other with column buoyancy aid 4; Described touch switch 6 is the trigger switch of warning device, and links to each other with power supply.

Embodiment 2: described touch switch 6 is the power cut-out switch of reactor 1 charge pump, links to each other with the dump line of reactor charge pump.

When overflow takes place when reactor 1 in the utility model, column buoyancy aid 4 rises with overflowing liquid, after rising to certain altitude, elastic washer 9 blocks opposing pipe 5 lower port, touch arm 6-1 simultaneously and touch its switch, give the alarm immediately, remind the operator to stop immediately reactor is added chemical liquid or cuts off the charge pump power supply automatically, stop to feed in raw material.

Above disclosed only is the utility model preferred embodiment, for example adopt infrared warning device etc. in addition, so can not limit interest field of the present utility model with this, therefore the equivalent variations of being done according to the application's claim still belongs to the scope that the utility model is contained.
