Description
Technical field
The utility model relates to a kind of large sealing formula tank body positive/negative-pressure integrated protective device being applicable to the anaerobic fermentation fields such as sewage treatment, changing food waste process, biogas engineering.
Background technique
Positive/negative pressure protection device is applicable to general sealed shell of tank.Increase when tank interior pressure or reduce, protector outwards can get rid of gas or inside suction gas.Reach the object of pressure in balance tank body, to protect the safety of tank body.
There is the larger problem of occupation area in the protective gear of prior art, and protective gear is arranged on tank body top more, because tip position is less, directly affects other equipment and install or use.In addition, prior art protective gear also exist reliability not high, protect problem not in place.
Summary of the invention
The purpose of this utility model provides a kind of integrated positive/negative pressure protective gear of large sealing formula tank body just for deficiency existing in above-mentioned prior art.
The purpose of this utility model realizes by following technical measures:
Large sealing formula tank body positive/negative-pressure integrated protective device of the present utility model comprise be provided with level meter malleation urceolus, be positioned at the negative pressure urceolus being provided with level meter below malleation urceolus; The top of malleation urceolus is provided with positive pressure ventilation mouth, is provided with the negative pressure inlet mouth that the gas pipeline of drawing with large sealing formula tank body is connected in the middle and upper part of described negative pressure urceolus; To be provided with cylinder in the malleation that top is enclosed construction with the mode of malleation urceolus coaxial line in the positive pressure protection cavity of malleation urceolus, be provided with the malleation inner core of hollow cylindrical structure in cylinder in the mode of Spielpassung in malleation, and be fixed together by malleation strut between cylinder and malleation inner core in malleation, in described malleation, cylinder lower edge mouth is positioned at below the liquid level of positive pressure protection cavity; The through hole Joint that the barrel lower end of described malleation inner core and positive press process, lower end mouth protects cavity to be connected with the negative pressure of negative pressure urceolus; To be provided with cylinder in the negative pressure that top is enclosed construction with the mode of negative pressure urceolus coaxial line in the negative pressure protection cavity of negative pressure urceolus, in negative pressure, in cylinder, be provided with the negative pressure inner core of hollow cylindrical structure in the mode of Spielpassung, and be fixed together by negative pressure strut between cylinder and negative pressure inner core in negative pressure; In described negative pressure, cylinder lower edge mouth is positioned at below the liquid level of negative pressure protection cavity, and the barrel lower end of described negative pressure inner core and negative pressure base plate Joint, lower end mouth is connected with air.
Between malleation urceolus and negative pressure urceolus, rubber gasket is installed described in the utility model, is bolted together.
Working principle of the present utility model is as follows:
When the air pressure in tank body is less than external atmosphere pressure; in negative pressure, the outer liquid level of cylinder rises; in negative pressure, in cylinder, liquid level declines; and drop to certain position; gas outside tank body just can protect the fluid-tight in cavity by negative pressure; enter tank interior, reach pressure in tank body and recover normal object, thus protection large sealing formula tank body.When tank interior pressure increases, first the gas in tank body enter negative pressure protection cavity, and enter positive pressure protection cavity by the center hole of negative pressure top board.When pressure in tank body continues to increase; in malleation, the outer liquid level of cylinder rises; in malleation, in cylinder, liquid level declines; when dropping to certain position; gas in tank body is just by the fluid-tight in positive pressure protection cavity; enter ambient atmosphere layer by positive pressure ventilation mouth, thus reach the pressure release object of large sealing formula tank body.Be respectively at positive pressure protection cavity and negative pressure protection cavity side the liquid level that malleation level meter and negative pressure level meter can show liquid feeding, instruct liquid to add.
The beneficial effects of the utility model are as follows:
1, positive/negative pressure protection device can effectively play a protective role to the harm that tank body causes about positive and negative pressure is excessive to large sealing formula tank body.
2, malleation and negative-pressure protection device integrated design, save material, occupation area is little.
3, malleation and negative-pressure protection device adopt water-sealed type principle, and rational in infrastructure, reliability is strong.Effectively avoid the unreliable problem that mechanical structure long-time running and other water-sealed type structures are brought.
