[0003] The traditional method is to manually feed the defoaming agent by using a glass burette, so that the reaction can be continuously stable, but due to the long reaction time, a person needs to pay attention to the defoaming agent in the glass burette at any time, which is time-consuming and laborious. CONTENT OF THE UTILITY MODEL
[0004] In view of the defects of the prior art, the application provides an automatic defoaming agent feeding device, which can automatically feed the defoaming agent, does not need a person to stand beside the feeding device, and can feed the defoaming agent in a timed and quantitative manner, thereby reducing the workload of the person and solving the problem that the traditional method is to manually feed the defoaming agent by using a glass burette, so that the reaction can be continuously stable, but due to the long reaction time, a person needs to pay attention to the defoaming agent in the glass burette at any time, which is time-consuming and laborious.
[0005] In order to achieve the purpose of automatically feeding the defoaming agent, not needing a person to stand beside the feeding device, and feeding the defoaming agent in a timed and quantitative manner and reducing the workload of the person, the application provides the following technical scheme: an automatic defoaming agent feeding device, comprising a liquid storage barrel, a connecting pipe is connected to the bottom of the liquid storage barrel, the bottom of the connecting pipe is connected to the top of a positioning frame, a liquid inlet is formed in the top of the positioning frame, the position of the liquid inlet corresponds to the position of the connecting pipe, two liquid outlets are formed in the bottom of the positioning frame, the positions of the liquid outlets are staggered with the position of the liquid inlet, a liquid adding box is slidably arranged on the inner wall of the middle part of the positioning frame, a plurality of partition plates are arranged on the inner wall of the middle part of the liquid adding box in an array, a plurality of liquid storage compartments are formed in the liquid adding box by the plurality of partition plates, first through holes corresponding to the positions of the liquid storage compartments are formed in the top and bottom of the liquid adding box, a groove plate is arranged on one side of the liquid adding box, a plurality of sliding grooves corresponding to the positions of the liquid storage compartments are formed in one side of the groove plate, the middle part of the inner wall of the sliding groove is slidably connected with the middle part of the outer surface of a sliding rod, one end of the sliding rod is arranged at the bottom of one end of a connecting rod, the other end of the connecting rod is arranged on the output shaft of a motor, and the motor is arranged on one side of the liquid storage barrel through a fixing block.
[0006] The above solution uses a motor to drive a connecting rod that slides within a trough. This trough plate then pushes the liquid addition box to move at fixed intervals, allowing the defoamer stored in the storage tank to be dispensed through the drain port. This achieves automatic defoamer dispensing without the need for manual supervision, and enables the dispensing of defoamer at fixed intervals and in fixed quantities, thus reducing manual workload.
[0007] Furthermore, a first sealing gasket is provided on the inner wall of the middle part of the positioning frame, and the inner wall of the first sealing gasket is slidably connected to the outer surface of the middle part of the liquid filling box.

[0011] Furthermore, a second sealing gasket is provided around the inner wall of the middle part of the liquid storage tank, and the inner wall of the middle part of the second sealing gasket is slidably connected to the outer surface of the middle part of the adjusting plate.
[0012] The above solution increases the sealing between the adjusting plate and the inner wall of the storage tank by setting the second sealing gasket, preventing the defoamer in the storage tank from entering the upper part of the adjusting plate through the gap between the adjusting plate and the inner wall of the storage tank, thus preventing it from affecting the adjustment of the storage tank's contents.
[0013] Furthermore, the inner walls on both sides of the middle part of the connecting plate are slidably disposed on the outer surface of the middle part of the two limiting rods, and the bottom of the two limiting rods are disposed in the inner wall of the middle part of the first through hole at the bottom of the liquid filling box through the support plate.
[0014] The above solution restricts the angle of movement of the connecting plate by setting the limit rod, thereby limiting the angle of movement of the adjusting plate and improving the stability of the adjusting plate during movement.
[0015] Furthermore, a corrugated hose is provided on the top of the adjustment plate, with one end of the corrugated hose located on the top of the inner wall of the liquid storage tank, and the two ends of the corrugated hose corresponding to the positions of the first through hole and the second through hole on the top of the liquid filling box, respectively.
[0016] Through the above scheme, the space between the top of the adjusting plate and the top of the inner wall of the liquid storage bin can be sealed through the setting of the corrugated hose, and the flexibility of the corrugated hose will not affect the movement of the adjusting plate.
[0017] Further, exhaust holes are formed through the top of the liquid adding box on both sides of the first through hole in the top of the liquid adding box.
[0018] Through the above scheme, the space above the adjusting plate can be exhausted through the setting of the exhaust hole, so that the adjusting plate can move smoothly in the liquid storage bin, and the adjusting plate is prevented from being affected by the air pressure in the space above the adjusting plate when moving in the liquid storage bin.
[0019] Further, a through slot is formed on one side of the positioning frame, and the width of the through slot is smaller than the thickness of the liquid adding box.
[0020] Through the above scheme, the slot plate can extend to the position of the positioning frame, so that the sliding rod can normally push the slot plate, and the positioning frame can normally limit the position of the liquid adding box.
[0021] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:
[0022] The automatic defoamer adding device can automatically add defoamer without manual intervention, and can add defoamer in a timed and quantitative manner, thereby reducing the workload of manual operation. BRIEF DESCRIPTION OF DRAWINGS
