Abstract
The utility model relates to a methane tank manhole cover explosion-proof decompression device, which comprises a pressure transmission controller and a decompression valve which are arranged on the manhole cover, wherein the pressure transmission controller is arranged on the manhole cover by a mounting plate. The pressure transmission controller is composed of a pressure sensor, a control circuit, a driving motor and a telescopic plug which corresponds to a jack on the manhole cover, and the pressure sensor is fixed on the mounting plate and is attached to the bottom of the manhole cover by penetrating through the manhole cover. When the pressure sensor knows and monitors the environmental pressure parameter by using the utility model, a signal is given to a data acquisition circuit. When the signal is matched with the setting pressure data, the motor driving mechanical part is started by the control circuit to release a decompression cover, and the hidden danger of safe operation is eliminated effectively. The utility model has the advantages of simple structure and convenient realization.
Description
Technical field
The utility model relates to the explosion-proof relief device, in particular for the explosion-proof relief device of methane-generating pit, septic tank.
Background technology
Along with the further raising that people require living environment, methane-generating pit and septic tank use more and more general in city and rural area, and various ight soil and sanitary wastewater all need to carry out pre-treatment through methane-generating pit or septic tank.The methane-generating pit of prior art and septic tank all adopt air-tight manner, prevent the leakage of biogas.But because there are a large amount of biogas in methane-generating pit and septic tank, can not get overstocking under the situation about discharging too high many for a long time, producing certain pressure and potential safety hazard occurs.Especially under the situation of climatic anomaly, facility is hurted sb.'s feelings, destroyed to the lighter's well lid of throwing; Weight person meets fire and blasts, and brings personal injury and property damage to citizen and urban construction.The whole nation all has a lot of methane-generating pits or septic tank blast every year, the incendiary incident takes place even, causes great potential safety hazard.
The utility model content
At the prior art above shortcomings, the purpose of this utility model is to provide a kind of explosion-proof relief device for methane-generating pit and septic tank well lid.
The purpose of this utility model is achieved in that methane-generating pit well lid explosion-proof relief device, comprises pressure transmission controller and the pressure release valve be located on the well lid, and the pressure transmission controller is located on the well lid by mounting plate; The pressure transmission controller is made up of pressure transmitter, pilot circuit and drive-motor and bullet bolt, and bullet bolt is corresponding with jack on the well lid; Pressure transmitter is fixed on the mounting plate and passes the bottom that well lid invests well lid.
Use the utility model when the pressure parameter of pressure transmitter perception monitoring of environmental, give signal of data acquisition circuit, this signal control circuit start motor when pressure data being set matching rotates, and mechanical part is decontroled the pressure release lid, has effectively eliminated potential safety hazard; Have simple in structure, the characteristics of being convenient to realize.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of pressure transmitter.
Fig. 3 is pilot circuit one an embodiment schematic circuit.
Embodiment
As shown in Figure 1, the utility model mainly comprises pressure transmission controller and the pressure release valve of being located on the methane-generating pit well lid 12.The pressure transmission controller is located on the methane-generating pit well lid 1 by mounting plate 3, and the pressure transmission controller is made up of pressure transmitter 4, pilot circuit and drive-motor and bullet bolt 5; Bullet bolt 5 is corresponding with jack 6 on the methane-generating pit well lid 1.Pressure transmitter 4 is fixed on the mounting plate 3 and passes the bottom that methane-generating pit well lid 1 invests well lid.
As shown in Figure 2, pressure transmitter 4 accompanies sponge electrical conductor 8 (RF) by two sheet metals 7 and forms.
Referring to Fig. 3, be pilot circuit one embodiment, comprise transmitter RF, operational amplifier A, amplifying relay Q, motor M and power supply E; K is a pressure transmitter 4 among the figure.The motor M starting is adopted and is exchanged or direct supply E, and direct supply can adopt No. 5 or No. 7 batteries.
Principle of work of the present utility model is as follows: the gaseous tension when pressure transmitter 4 outsides reaches setting monitoring concentration value, the metal copper sheet promotes the conductive sponge attenuation, resistance reduces, 3 pin of operational amplifier are in high level, through amplifying relay Q adhesive K1, this signal rotates by pilot circuit starter motor 5 expansion link 6 is retreated, after the connection motor M drives transmission latch release (promptly withdrawing from), pressure release is covered under environmental stress and is opened automatically, emits the generation that accident is avoided in the gas decompression.This monitor pressure monitoring value setting is just discharging, pressure release when gas concentration does not reach detonation point as yet, therefore, can avoid causing burning when pressure release.After the decompression, manually close the cover is plugged latch and is recovered monitoring automatically.Referring to Fig. 1, pressure release valve 2 cuts out by 6 actions of motor M control bullet bolt.
Claims (2)
1, methane-generating pit well lid explosion-proof relief device is characterized in that comprising pressure transmission controller and the pressure release valve (2) be located on the well lid (1), and the pressure transmission controller is located on the well lid (1) by mounting plate (3); The pressure transmission controller is made up of pressure transmitter (4), pilot circuit and drive-motor and bullet bolt (5); Pressure transmitter (4) is fixed in mounting plate (3) and goes up and pass the bottom that well lid (1) invests well lid.
2, explosion-proof relief device according to claim 1 is characterized in that described pressure transmitter (4) presss from both sides a sponge electrical conductor (8) by two sheet metals (7) and forms.
