Detailed description of the invention
For making object, technical scheme and the advantage of embodiments of the invention clearer, below in conjunction with the present inventionAccompanying drawing in embodiment, the technical scheme in the embodiment of the present invention is known to complete description:
Embodiment 1, as shown in Figure 1: a kind of autobalance foam-making apparatus, mainly comprises: as reactionThe tank body 1 of container. Being arranged on the inlet 5 of described tank body 1 upper end, is only a kind of concise and to the point shown in Fig. 1The form of expression. In the time that reality is used, can be according to service condition, inlet 5 places arrange internal thread or outside spiral shellLine, so that the pipeline of the different pore size of plugging into. Meanwhile, the dimension scale of inlet 5, is not subject to accompanying drawing 1 yetRestriction, can, according to the difference in the pipeline aperture of plugging into, change self aperture; Also by the aforesaid change that is threadedThe pipe joint in footpath.
Also be provided with liquid gas mixing portion 8 on the top of tank body 1, the portion of liquid gas mixing in the present embodiment 8 is perpendicular by oneStraight overflow pipe 2 imbitition from tank body 1 causes described liquid gas mixing portion. In the present embodiment, instituteThe lower ending opening of the overflow pipe 2 of stating is arranged on the bottom of tank body 1.
Also be provided with gas-liquid mixed mouth 4 in liquid gas mixing portion 8, extraneous gas (air etc.) is by this gas-liquid mixedMouth 4 enters liquid gas mixing portion 8 to be mixed with liquid, after foam generated, is sprayed by jet pipe 7.
In order to adjust air inflow, as preferred embodiment, establish at described gas-liquid mixed mouth 4 placesBe equipped with volume control device 6, in this device, be provided with and regulate by the air inlet adjustment of gas-liquid mixed mouth 4 gas flowsCone 61.
When liquid gas mixes, go deep into the length of gas-liquid mixed mouth 4 by adjusting air inlet adjustment cone 61, control gasEnter the flow of described liquid gas mixing portion 8.
As preferred embodiment, described volume control device 6 is a change aperture pipe, as Fig. 2 instituteShow this pipe from outside to inside, comprise the pipe that 2 knothole footpaths diminish gradually. Described air inlet adjustment cone 61 comprisesOne outer seat 611, the external diameter of this outer seat 611 is greater than the external diameter of described pipe, prevents that cone governor from too going deep into gasLiquid mixes mouth 4, causes being difficult for exiting.
Consider the front end of cone governor, comparatively approaching with gas-liquid mixed mouth 4, approach swiftly flowing liquid simultaneouslyBody and gas, easily cause corrosion and damage cone back segment not fragile on cone surface. PretendFor preferred embodiment, described air inlet adjustment cone 61 comprises the leading portion 613 of releasable connection and isodiametricBack segment 612. Can adopt the existing releasable connection modes such as screw thread, while facilitating front end 613 to damage, can be timelyChange.
For the gases at high pressure that prevent tank body 1 inside leak, as preferred embodiment, gas by withThe breather cheek valve 3 that liquid gas mixing portion 8 exocoels are communicated with enters liquid gas mixing portion.
Further, in order to prevent the hypertonia of tank body 1 inside, cause danger, as preferred realityExecute mode, described tank body 1 is also provided with Pressure gauge 9, and the decompression force that facilitated duty personnel, in the situation of superpressureLower shutdown system. Also be provided with relief valve 11, prevent from meeting accident in the time of unmanned.
Embodiment 2, the present embodiment is identical with the critical piece of embodiment 1, and the main distinction is the tank body adopting1a is horizontal. Overflow pipe 2a is arranged on the middle part of tank body 1, gos deep into the bottom of tank body 1a. Air is by singleEnter the gas-liquid mixed portion that is arranged on tank body 1a top to intake valve 3a.
