Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

The slit is arranged to enable the mucilage to pass through smoothly, and on the basis that the mucilage can pass through, the smaller the slit is, the better the slit is, the mucilage can conveniently hang and flow after contacting with the inner side wall of the trough 10, the size of the slit is also influenced by the viscosity of the mucilage, and the slit is not used for processing the mucilage with certain specific viscosity; in addition, the aperture of the screen hole 201 is also selected according to different mucilage, and is not described in detail herein.

As shown in fig. 1, the present embodiment provides a bubble removing device for polymer cement production, which includes a trough 10 and a sieve tray 20 whose bottom covers the opening of the trough 10; the sieve tray 20 is cylindrical, and the bottom of the sieve tray is provided with a plurality of sieve holes 201; the sieve tray also comprises a connecting rod 30 and a conical guide plate 40, wherein the upper end of the connecting rod is vertically fixed at the center of the bottom of the sieve tray 20; the top of guide plate 40 and the lower extreme fixed connection of connecting rod 30, guide plate 40, connecting rod 30 all set up coaxially in the space that sieve tray 20 and silo 10 enclose closed, leave the slit between the bottom edge of guide plate 40 and the silo 10 inside wall.

The working principle is as follows: pouring the mucilage into the sieve tray 20, and removing bubbles by allowing the mucilage to pass through the sieve holes 201 at the bottom of the sieve tray 20 under the action of gravity; the mucilage drips on the conical surface of the guide plate 40, flows down around along the conical surface under the action of gravity, flows to the edge of the conical surface of the guide plate 40, generates a hanging flow phenomenon after contacting with the inner side wall of the trough 10 due to certain viscosity, and flows to the bottom of the trough 10 along the inner side wall of the trough 10 under the resistance of the inner side wall of the trough 10. The guide plate 40 is fixed on the sieve tray 20 instead of the trough 10, and the blockage of the guide plate 40 to the mucilage in the trough 10 can be removed only by taking out the sieve tray 20, so that the discharging is facilitated; if the guide plate 40 is fixed on the trough 10, the discharge can be carried out only from the slit during the discharge, and the inner conical surface of the guide plate 40 is easy to have mucilage residue, which is inconvenient for cleaning.

In order to prevent the mucilage from separating from the inner side wall of the trough 10 and directly dripping after the inner side wall of the trough 10 is enriched due to overlarge flow of the mucilage, the trough 10 is in a circular truncated cone shape with a wide trough opening and a narrow trough bottom. When the flow of mucilage is too big, even there is some thick liquids to become to drip in the enrichment of the position of being close to silo 10 inside wall, at the in-process that falls down, because silo 10 inside wall slope, the mucilage that becomes drips forms the trickle again with the contact of silo 10 inside wall of slope behind the vertical fall, avoids appearing direct drippage phenomenon.

In order to realize the adjustment of the size of the slit, the connecting rod 30 is an electric telescopic rod, the guide plate 40 can be controlled by the electric telescopic rod to move up and down, the power supply mode of the electric telescopic rod is the prior art, the trough 10 with a wide trough opening and a narrow trough bottom is arranged from top to bottom, the radius of the inner wall is gradually reduced, and therefore the size of the slit is controlled by the electric telescopic rod to move up and down on the guide plate 40, so that the slit is suitable for removing bubbles of different mucilage.

In order to ensure the normal use of the electric telescopic rod, the electric telescopic rod further comprises a corrugated pipe 60, the upper end of the corrugated pipe 60 is fixed at the bottom of the sieve tray 20, the lower end of the corrugated pipe 60 is fixed at the guide plate 40, and the connecting rod 30 is sealed in a cavity enclosed by the sieve tray 20, the corrugated pipe 60 and the guide plate 40. Avoid the adhesive cement to adhere on electric telescopic handle, influence electric telescopic handle's flexible.

For the convenience of fast assembly of the sieve tray 20, the annular positioning ring 50 is fixed at the notch end of the trough 10, the positioning ring 50 is coaxial with the trough 10, the inner diameter of the positioning ring 50 is equal to the outer diameter of the sieve tray 20, the inner wall surface of the positioning ring 50 and the inner wall surface of the trough 10 form an annular stepped groove, the sieve tray 20 is embedded in the annular stepped groove, and the sieve tray 20 is respectively contacted with the inner wall of the positioning ring 50 and the notch end of the trough 10.

In order to accelerate the treatment capacity of the mucilage, the device also comprises a vacuum pump, and an air suction opening of the vacuum pump is connected with the material groove 10 through a pipeline. When the mucilage comes, the screen holes 201 are sealed in a liquid mode, air in the trough 10 is pumped through the vacuum pump at the moment, the screening speed can be increased, and a small amount of fine bubbles remained in the mucilage in the process that the sieved mucilage flows to the bottom of the trough 10 in a hanging mode can be removed; the drainage of the guide plate 40 and the wall hanging flow on the inner side of the trough 10 delay the enrichment speed of the mucilage, so that the vacuum defoaming effect is enhanced, and the part, far away from the liquid level, of a large amount of enriched mucilage is not easily influenced by negative pressure.

In order to reduce the flow rate of the mucilage, the conical angle of the guide plate 40 is 160-170 degrees. The conical surface slope of guide plate 40 is less, reduces the horizontal acceleration of mucilage, prevents that the mucilage horizontal velocity from assaulting 10 inside walls of silo at the excessive speed and arousing to splash, guarantees to hang and flows the effect.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
