[0002] The defoaming device usually uses physical or chemical methods to eliminate the foam in the sulfur foam tank. Physical methods include mechanical stirring and ultrasonic vibration, which break the foam by destroying its stability. The chemical method is to add defoaming agents, which can reduce the surface tension of the foam and cause the foam to break and disappear quickly.

The method for using a sulfur foam tank defoaming device according to claim 9, characterized in that: The following steps are involved: Step 1: under the driving action of the first motor (16), the motor shaft of the first motor (16) drives the driving gear (17) to rotate synchronously, the driving gear (17) then meshes to drive the fixed gear ring (15) to rotate along the channel steel ring (14), and the fixed gear ring (15) then meshes to drive the driven gear (21), the driven shaft (2), and the crank swing arm (22) to rotate; The crank swing arm (22) drives the hinged ear seat (23) to perform crank swing arm movement, and drives the U-shaped clamping plate (24) to slide back and forth along the trapezoidal slide plate (27), and simultaneously drives the rectangular slide plate (26) to slide back and forth along the rectangular slide hole, and drives the lifting cover plate (3) to slide back and forth along the open cylinder (1); Step 2: under the driving action of the second motor (5), the motor shaft of the second motor (5) drives the driving large gear (51) and the driving small gear (52) to rotate synchronously, and the driving small gear (52) meshes to drive the driven internal gear ring (54) to rotate along the three F-shaped slide seats (53); The driven internal gear ring (54) then meshes and drives the driven pinion (41), the central shaft (4), the fixed bevel gear (42), the three-claw plate (43), the planetary vertical shaft (44), the planetary widening gear (45), and the second stirring paddle (46) to revolve, and the planetary widening gear (45) meshes and rotates along the fixed internal gear ring (47), and drives the planetary vertical shaft (44) and the second stirring paddle (46) to rotate, so that the second stirring paddle (46) performs planetary rotation; Step 3: The driving large gear (51) meshes with the driven large gear (33), the hollow shaft (32), the planetary transverse shaft (34), the planetary bevel gear (35), and the first stirring paddle (36) to perform reverse revolution, and the planetary bevel gear (35) then meshes with the fixed bevel gear (42) to perform rotation, and drives the planetary transverse shaft (34) and the first stirring paddle (36) to perform rotation, so that the first stirring paddle (36) performs reverse planetary rotation; The reciprocating lifting and sliding movement of the lifting cover plate (3) drives the first stirring paddles (36) and the second stirring paddles (46) to synchronously lift and reciprocate, and drives the planetary widening gear (45) to slide and reciprocate along the fixed internal gear ring (47); Step 4, injecting the sulfur foam to be treated into the open cylinder (1) through the liquid inlet pipe (11), controlling the injection speed and amount to prevent the sulfur foam from overflowing, and using the first stirring paddle (36) and the second stirring paddle (46) together to uniformly and fully stir the sulfur foam, thereby destroying the stability of the sulfur foam by stirring, causing the bubbles to burst, and achieving the purpose of defoaming. During the stirring process, the defoaming of the sulfur foam is closely observed. When the defoaming effect reaches the required level, the discharge pipe (12) is opened, and the treated sulfur foam is discharged along the discharge pipe (12).
