Description

Technical Field

[0001] The invention relates to the field of defoaming agent impurity removal, and in particular to a defoaming agent impurity removal and purification device. Background Art

[0002] Defoaming agent is a substance that can reduce the surface tension of liquid, prevent the formation of foam or eliminate the original foam. After the production of defoaming agent is completed, there will be some small solid impurities such as unreacted raw materials, by-products, catalyst residues, etc. in the reaction system. The presence of these impurities will affect the performance of the defoaming agent. Therefore, after the reaction is completed, it is necessary to remove impurities and purify it immediately.

[0003] At present, the common defoaming agent impurity removal devices are generally vibrating screen filters and bag filters. These filtering devices use the filtering capacity of filter screens or filter bags to separate defoaming agents and impurities. However, as time goes by, impurities on the filter screen will gradually accumulate, and the filter screen needs to be frequently replaced or cleaned. The time spent on cleaning the filter screen is relatively long, resulting in low impurity removal efficiency. In addition, since the defoaming agent has a certain viscosity, more defoaming agent will adhere to the separated impurities. However, the existing devices generally remove the separated impurities directly after one filtration, and more defoaming agent will adhere to the impurities, resulting in a higher defoaming agent loss rate. Summary of the invention

When it rotates to the top of the filter screen 2, under the action of the gear rack, the gear 4 will rotate and drive the salvage plate to rotate through the shaft 2. After the salvage plate rotates to a vertical state, the picked up impurities will fall downward to the interception plate and filter screen 2 under the action of gravity, which can accelerate the separation of impurities deposited at the bottom of the inner wall of the cylinder and further improve the impurity removal efficiency.

[0036] The jacking assembly includes a rotating shaft 75 connected between the vertical plate 2 and the protective shell 3 through a bearing, an arc-shaped rack 76 fixed to one side of the cylinder 61, a gear 3 77 fixed to the rotating shaft 75, the arc-shaped rack 76 and the gear 3 77 meshing, a guide frame 78 connected to the inner wall of the protective shell 3 through bolts, a turntable 79 rotatably connected to the guide frame 78, a transmission assembly 710 arranged between the turntable 79 and the rotating shaft 75, and a contact shaft 711 fixed to the turntable 79. The cylinder 61 drives the gear 3 77 to rotate through the arc-shaped rack 76, and then drives the gear 3 77 through the rotating shaft 75 and the transmission assembly 710. The turntable 79 and the contact shaft 711 rotate, and the sliding frame 712 is slidably connected to the side of the guide frame 78, and is fixed to the one-shaped slot frame 713 at the bottom of the sliding frame 712. The one-shaped slot frame 713 has a contact slot, and one end of the contact shaft 711 is located in the contact slot of the one-shaped slot frame 713. The two rollers 714 are rotatably connected to the upper part of the sliding frame 712. The two rollers 714 are symmetrically arranged, and the rollers 714 are in contact with the bottom of the second filter screen 73. The contact shaft 711 drives the sliding frame 712 and the rollers 714 to move upward through the one-shaped slot frame 713, thereby pushing the second filter screen 73, the intercepting plate 72 and the rotating frame 71 upward.

[0037] The transmission assembly 710 is composed of a driving wheel, a driven wheel and a transmission belt. The driving wheel of the transmission assembly 710 is fixedly connected to the rotating shaft 75, the driven wheel of the transmission assembly 710 is fixedly connected to the turntable 79, and the transmission belt of the transmission assembly 710 is wound between the driving wheel and the driven wheel of the transmission assembly 710.

[0038] Initially, the discharge valve 68 is in a closed state, and the supporting rib 5 supports the rotating frame 71, thereby supporting the interception plate 72 and the filter screen 2 73. After starting work, the staff opens the discharge valve 68, starts the servo motor 63 and the electric blower 74, and uniformly adds defoaming agent into the lower hopper 67. The electric blower 74 blows air downward, and the defoaming agent flows into the lower part of the cylinder 61 through the guide of the lower hopper 67. The limiting ring 69 limits the defoaming agent to prevent the defoaming agent from overflowing. The filter screen 1 62 filters the defoaming agent, and the impurities in the defoaming agent will remain on the filter screen 1 62. The filtered defoaming agent will pass through the filter screen 1 62 under the action of gravity and fall downward. The collecting bucket 66 collects the defoaming agent passing through the filter screen 1 62, and the inclined surface at the bottom of the collecting bucket 66 will filter the defoaming agent. The defoaming agent is guided to the discharge valve 68 and discharged through the discharge valve 68. Since the defoaming agent has a certain viscosity, impurities and a small amount of defoaming agent will adhere to the surface of the filter screen 62 and rotate with it. The output shaft of the servo motor 63 rotates to drive the gear 1 64 to rotate, and the rotation of the gear 1 64 drives the gear 2 65 to rotate. The rotation of the gear 2 65 drives the cylinder 61 to rotate. The rotation of the cylinder 61 drives the filter screen 1 62 to rotate. The rotation of the filter screen 1 62 drives the impurities and a small amount of defoaming agent adhered to its surface to rotate. When the filter screen 1 62 rotates to the bottom of the electric blower 74, the wind blown by the electric blower 74 blows off the impurities and a small amount of defoaming agent adhered to the surface of the filter screen 1 62. Through the above operation, the filter screen can be cleaned conveniently while filtering, reducing the time spent on cleaning the filter screen. The impurities and a small amount of defoaming agent adhered to the surface of the filter screen 1 62 are blown down and fall downward, and are caught by the rotating frame 71, the intercepting plate 72 and the filter screen 2 73 below. The filter screen 2 73 performs secondary filtration on the impurities and a small amount of defoaming agent. The impurities will remain on the top of the filter screen 2 73, and a small amount of defoaming agent will fall into the cylinder 61 again. Through the above operation, the defoaming agent remaining on the impurities can be reduced, and the loss rate of the defoaming agent can be reduced. The rotation of the cylinder 61 drives the arc rack 76 to rotate, and the arc rack 76 rotates to mesh with the gear 3 77, and drives the gear 3 77 to rotate. The rotation of the gear 3 77 drives the rotating shaft 1 75 to rotate. The rotating shaft 1 75 drives the rotating disk 79 to rotate through the transmission assembly 710. The rotation of the rotating disk 79 drives the contact shaft 711 to rotate. The rotation of 711 pushes the one-shaped slot frame 713 upwards, and the one-shaped slot frame 713 moves upward to drive the sliding frame 712 to move upwards, and the sliding frame 712 moves upward to drive the roller 714 to move upwards, and the roller 714 moves upward to lift the second filter screen 73, the intercepting plate 72 and the rotating frame 71 upwards, and the rotating frame 71 is out of contact with the supporting rib 5, and the second filter screen 73, the intercepting plate 72 and the rotating frame 71 will rotate upward to an inclined state. Under the action of gravity and the inclined state, the impurities on the second filter screen 73 and the intercepting plate 72 will roll down and fall to the ground, and the contact shaft 711 continues to rotate to push the one-shaped slot frame 713 downwards, and the one-shaped slot frame 713 moves downward to drive the sliding frame 712 to move downward, and the sliding frame 712 moves downward to drive the roller 714 to move downward.The roller 714 no longer lifts the filter screen 2 73. Under the action of gravity, the filter screen 2 73, the intercepting plate 72 and the rotating frame 71 will be reset to the initial state, and the supporting rib 5 will support the rotating frame 71, the intercepting plate 72 and the filter screen 2 73 again. The arc rack 76 continues to rotate and disengages from the gear 3 77. Through the above operation, the impurities separated from the filter screen 2 73 can be cleaned intermittently to avoid excessive accumulation of impurities on the filter screen 2 73 and affect the filtering effect and efficiency, so as to facilitate continuous work. After the filtration is completed, the staff stops introducing the defoaming agent into the lower hopper 67, turns off the servo motor 63, waits for the defoaming agent on the filter screen 1 62 and the filter screen 2 73 to drain and no more defoaming agent flows out of the discharge valve 68, and then turns off the electric blower 74 and the discharge valve 68.

[0040] The two sets of inclined blocks 84 and the arc-shaped rack 76 on the cylinder 61 are staggered to avoid conflicts caused by the simultaneous cleaning of impurities and the shaking of the filter screen 73.
