Example one
The device for automatically removing the liquid level fine foam shown in figure 1 consists of three parts, namely a foam removing system, a suction system and a platform height adjusting system. Wherein the main task of the defoaming system is to timely remove floating foam on the liquid surface of the liquid medicine; the suction system has two functions of air suction and air blowing, when the air suction function is started when froth is required to be absorbed in a matching manner, and when too much slag is adsorbed on the filter screen, the air blowing function is started to blow away the slag on the filter screen, and the function can be similar to the back washing function of a pipeline structure.
As a preferable aspect of this embodiment, specifically, the apparatus includes: the defoaming platform 3 is arranged above the liquid level;
the slag separation coarse net 7 is fixed on the lower surface of the foam removing platform 3, the slag separation coarse net 7 comprises a vertical wall surface, the lower part of the slag separation coarse net 7 can be a bottom structure or a bottomless structure, and when the slag separation coarse net 7 has a bottom, the middle part of the bottom surface is provided with a through hole through which the foam absorbing cylinder 6 can penetrate;
3 floater subassemblies including rotating the floater 1 of connecting rod 2 and the 2 free ends of connecting rod of connection on the 3 lower surfaces of defoaming platform, floater subassembly circumference array is on 3 lower surfaces of defoaming platform, and sets up and is separating the thick 7 outsides of net of sediment.
When the defoaming platform 3 is placed in the liquid level of the extraction tank, the three floating balls 1 are automatically positioned in the center of the liquid level in the tank when the liquid level is opened, and the lower part of the slag separation coarse screen 7 extends below the liquid level.
The adjusting assembly is arranged at the upper part of the defoaming platform 3, and comprises a platform height adjusting screw rod 16 which is in a lifting type and penetrates through the defoaming platform 3 and is used for adjusting the opening angle of the corresponding connecting rod 2; it is worth noting that a platform height adjusting screw 16 is correspondingly arranged at the upper part of each floating ball assembly, the overlooking projection of the central axis of each platform height adjusting screw 16 is positioned in the overlooking projection of the corresponding connecting rod 2, and the connecting rod 2 is adjusted to form an included angle with the defoaming platform 3 through the platform height adjusting screw 16 at the upper part of the connecting rod 2.
Due to the structural arrangement, when the floating ball assembly is fully opened, an acute angle still exists between the connecting rods 2 and the defoaming platform 3, and the included angle between two adjacent connecting rods 2 projected in the same plane cannot be absolute 180 degrees, but can be an obtuse angle close to 180 degrees. When the platform height adjusting screw 16 moves downwards through rotation, the obtuse angle formed by the projection of the two connecting rods 2 in the same plane is gradually reduced, so that the height of the defoaming platform 3 is relatively raised.
When the steam pressure fluctuates greatly due to some reason, the boiling of the liquid medicine in the extraction tank also generates large fluctuation, even bumping. At this time, the high pressure fan 8 sucks a large amount of the extraction liquid in addition to the light and thin foam. At this point, the defoaming stage 3 must be raised: the regulator outside the operation tank is controlled and installed on the defoaming platform 3 through the speed regulating motor 14, the speed regulating motor 14 drives the gear box 15 to drive the platform height regulating screw 16 to rotate, the connecting rod 2 of the floating ball 1 is driven through the regulating screw, the distance between the central defoaming cylinder 6 of the defoaming platform 3 and the liquid level is changed under the support of the floating ball 1, and therefore the phenomenon of water pumping is eliminated. The lifting of the platform height adjusting screw 16 is similar to the principle of a linear lifting module or a screw nut, and as shown in fig. 1, a nut structure which is in sleeve fit with the platform height adjusting screw 16 is really arranged on the defoaming platform 3.
High pressure positive blower 8 is connected to suction tube 9, one end, and the other end from top to bottom runs through to be fixed in the middle part of defoaming platform 3, and suction tube 9 lower part free end sets up suction opening 4, and when defoaming platform 3 placed on the page, the floating ball subassembly opened, and suction opening 4 sets up in the level top of defoaming platform 3 below, under 8 negative pressure state of high pressure positive blower, with near the foam suction opening 4 suction to in the suction tube 9.
The medicinal materials are heated by the jacket in the extraction tank, the medicinal liquid rises along the tank wall after being heated and boiled and rolls centripetally, and the floating foam is pushed to the center of the liquid level of the tank body. The foam in the narrow region between the defoaming stage 3 and the liquid surface is immediately sucked by the central suction port 4 of the defoaming stage 3 and is discharged to the outside of the apparatus through the suction pipe 9.
This equipment still includes: one end of the back flushing pipe 12 is connected with the high pressure fan 8, and the other end penetrates through the defoaming platform 3 from top to bottom.

The negative pressure end is used as power for sucking the medicine foam; the positive pressure end has the function of back flushing floating medicinal materials blocked on the periphery of the coarse screen. In order to enhance the back-blowing force of the positive pressure end, the back-blowing electromagnetic valve 10 is opened during back-blowing, and the exhaust electromagnetic valve 11 is closed at the same time. The negative pressure end still keeps the continuous suction and defoaming functions during back blowing.
Example two

The embodiment of this disclosure still provides an automatic clear liquid level slight foam device, including above-mentioned any technical scheme, therefore, has this automatic clear liquid level slight foam device's whole beneficial technical effect, and here, the retrench is given no longer.
As shown in fig. 1, the present disclosure further includes a foam absorbing cylinder 6, and the foam absorbing cylinder 6 is sleeved outside the suction port 4.
The foam suction cylinder 6 comprises an inner layer and an outer layer of coaxial fine filter screens 5, wherein the axial length of the outer layer of fine filter screens 5 is half of the axial length of the inner layer of fine filter screens 5.
The horizontal position of the lower end of the inner layer fine filtering mesh 5 is lower than that of the lower end of the coarse slag-isolating mesh 7.
The floating ball 1 descends along with the liquid level during the evaporation process. Therefore, the distance between the foam suction cylinder 6 at the center of the foam removing platform 3 and the liquid surface is always constant. When the liquid level fluctuates, in order to keep the minimum resistance and the maximum suction force at the lowest end of the foam absorbing cylinder 6 all the time, the upper layer and the lower layer of the foam absorbing cylinder 6 adopt stainless steel wire meshes with the same mesh number as the fine foam filtering mesh 5, the inner layer adopts a single layer, and the outer layer is formed by adding one layer on the basis of the single layer.
When the liquid level slightly fluctuates to the bottom end of the foam absorbing cylinder 6, the foam can be absorbed even though the liquid level is low in suction force due to the fact that the upper end is dense in double layers and the lower end is sparse in single layers; when the liquid level slightly fluctuates to the middle part of the foam absorbing cylinder 6, the liquid medicine can not be taken away due to the fact that the double layers at the upper end are dense, and the foam can be pumped out under the action of the power of the high-pressure fan 8. The fine medicine dregs are filtered by the fine filtering mesh 5. A slag separation coarse mesh 7 is arranged at the bottom of the defoaming platform 3 around the periphery of the foam absorbing cylinder 6 in a large range. The coarse slag-separating mesh 7 with a larger diameter increases the area for blocking more coarse slag.

The platform height adjusting screw 16 is screwed on the defoaming platform 3 through a thread structure, and a driven gear meshed with the main gear is arranged at the upper part of the platform height adjusting screw 16.
When the steam pressure fluctuates greatly due to some reason, the boiling of the liquid medicine in the extraction tank also generates large fluctuation, even bumping. At this time, the height of the foam rapidly rises to fill the space between the foam removing platform 3 and the liquid surface, and the high-pressure air sucks a large amount of the extracting solution in addition to the light and thin foam. At this time, the defoaming platform 3 must be improved, and the solution is as follows: the regulator outside the operation jar, the control is installed at the buncher 14 on defoaming platform 3, and buncher 14 drives the gear train in the gear box 15, and drive platform height adjusting screw 16 is rotatory, and the rotatory connecting rod 2 that promotes floater 1 of platform height adjusting screw 16 rotates to defoaming platform 3 central direction, has improved the distance of a section of thick bamboo 6 of inhaling at defoaming platform 3 center and liquid level under the support of floater 1, has solved the problem of row's extract. The selected speed regulating motor 14 is a positive and negative rotation motor, and the distance between the foam absorbing cylinder 6 and the liquid level can be finely controlled by matching a proper rotation speed ratio, so that the foam can be absorbed just and the liquid medicine cannot be pumped away. The device comprises an external protective shell, and a driving component for driving the platform height adjusting screw 16 to ascend and descend is fixed in the protective shell, namely a main gear in a gear box and a driven gear meshed with the main gear are rotationally arranged in the protective shell. And the rotating shafts of the main gear and the driven gear are both vertically arranged.
