Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

As shown in fig. 1 to 3, the present invention provides a sedimentation device for waste glaze recycling, which includes a cylindrical barrel 1, wherein the upper portion of the barrel 1 is provided with a plurality of inlets 11, the lower portion of the barrel 1 is provided with a plurality of outlets, the outlets are provided with detachable sealing plates 12, the sealing plates 12 are hermetically connected with the outlets, the sealing plates 12 can be detachably arranged on the barrel 1 by bolts, and the sealing plates 12 are provided with rubber sealing rings to achieve a sealing effect; a rotatable stirring device is arranged at the center of the cylinder body 1, a plurality of guide plates 2 which are uniformly distributed along the circumferential direction are fixed on the side wall of the cylinder body 1, and the guide plates 2 are spiral;

the spiral direction of the guide plate 2 is the same as the liquid flowing direction in the cylinder 1, as shown in fig. 1 and fig. 2, an arrow E represents the liquid flowing direction and the spiral direction of the guide plate 2 in the circumferential direction (the circumferential direction refers to the circumferential direction of the cylinder 1), the arrangement enables the liquid flowing direction to be consistent with the spiral direction of the guide plate 2, and then the liquid can continue to flow by the arrow E under the condition that the guide plate 2 exists, so that the flowing direction of the liquid is prevented from being damaged, and precipitates can be gathered on the cylinder wall 1 by means of centrifugal action;

further, as shown in fig. 2, in the axial direction of the cylinder 1, when the sediment converged on the guide plate 2 is urged by the rotation of the liquid, the flowing direction of the liquid is the same as the rotating direction of the guide plate 2, so that the sediment flows along the flowing direction of the liquid and simultaneously generates an axial sinking effect along the guide plate 2, and is further deposited at the bottom of the cylinder 1;

the preferred construction of the baffle 2 is as follows: the number of turns of the spiral line corresponding to the guide plate 2 is between 0.3 and 0.4, the ratio of the pitch of the spiral line to the radius corresponding to the spiral line is not less than 8, and the spiral line is respectively a schematic diagram of the guide plate 2 in the axial direction and the circumference by combining with fig. 5 and fig. 7, wherein a dotted arrow represents that the guide plate 2 shields the arrow, and the arrow represents that the arrow does not shield the guide plate 2, as shown in the following fig. 10;

as shown in fig. 5, the number of turns of the baffle 2 is 0.3, and the ratio of the pitch of the spiral line to the corresponding radius of the spiral line is 8; the arrangement of the baffle 2 can make the baffle 2 form a twist (the twist is indicated by an arrow F in the figure), that is, the baffle 2 can form an X-shape (as shown in fig. 6, the X-shape is formed after simplifying the twist) when viewed in the axial direction, so that when liquid flows through the baffle 2, the flow direction shown by the arrow in fig. 5 can be generated, and further, the sinking effect in the axial direction can be generated; with reference to fig. 7, a circumferential flow effect can be generated, and the flow direction of the liquid is consistent with the flow direction of the liquid, so that the damage to the flow direction of the liquid is avoided, and it can be seen that the flow direction of the liquid on the flow guide plate 2 is basically consistent;

referring to fig. 8, the number of turns of the baffle 2 is 0.3, and the ratio of the pitch of the spiral line to the radius of the spiral line is 2, it can be seen that, although the baffle 2 can still form a twisted part (i.e. having an X shape), the X-shaped position moves downward (as shown by arrow F'), and the degree of twist is also reduced, and the limit is used to judge that when the degree of twist approaches no-limit (i.e. no twist is generated), the sinking tendency of the liquid in the axial direction also approaches zero, so it can be judged that the sinking effect of the baffle 2 in fig. 8 is reduced although it has the sinking tendency;

referring to fig. 9, the number of turns of the baffle 2 is 0.3, and the ratio of the pitch of the spiral line to the radius corresponding to the spiral line is 20, it can be seen that the structure is substantially the same as that of fig. 5, that is, the length of the baffle 2 in the axial direction in fig. 9 is increased, so that a specific ratio can be reasonably selected according to the actual equipment size (i.e., the selection is performed when the ratio is greater than 8);

as shown in fig. 10, the number of turns of the baffle 2 is 0.6, and the ratio of the pitch of the spiral line to the corresponding radius of the spiral line is 8; it can be seen that when the number of turns is too large, the baffle 2 will produce two twists, so when the liquid flows through, its flow direction will change, and then destroy the flow direction of the liquid in the cylinder (i.e. the direction of arrow E), if the flow direction of the liquid in the cylinder is the same as the uppermost arrow in the figure, then the lowermost arrow in the figure is affected by the twist, and will produce the direction opposite to the flow direction of the liquid in the cylinder, and then destroy the flow direction of the liquid in the cylinder.

Further, as shown in fig. 4, the guide plate 2 is close to the one end of the barrel 1 diapire with contained angle B has between the diapire of barrel 1, and this contained angle is the acute angle, and is not more than 45 degrees, the setting of this contained angle for the rivers of bottom can flow through this contained angle, and then the indirect radius that has improved bottom rivers (owing to do not have sheltering from of guide plate 2, so its rivers pivoted radius is then indirect increase), according to being closer to the center, circumferential velocity is big, and then make the velocity of flow production of bottom reduce, promoted the precipitate and subsided.

As shown in fig. 1 and 4, the stirring apparatus includes a stirring shaft 3 coaxial with the cylinder 1, a plurality of stirring blades 31 uniformly distributed along the circumferential direction are fixed on the stirring shaft 3, a motor 4 for driving the stirring shaft 3 to rotate is fixed on the upper portion of the cylinder 1, the stirring blades 31 are arc-shaped, the central angle corresponding to the arc-shaped stirring blades is an obtuse angle, the rotation direction of the stirring shaft 3 is shown by an arrow D in fig. 1, and then the water flow in the cylinder generates the flow direction of the arrow E.

When the device is used, the waste glaze liquid is poured into the barrel body 1 through the inlet 11, the pouring amount of the waste glaze liquid is not more than 3/4 (shown as d in fig. 4) of the length of the guide plate 2, then the motor 4 is started, the motor 4 drives the stirring shaft 3 to rotate, and it needs to be noted that the rotating speed of the stirring shaft 3 is low-speed rotation, and if the rotating speed is too high, the sedimentation effect cannot be achieved, so the rotating speed can be set between 40 and 50 revolutions per minute, and other specific rotating speeds can be selected according to actual conditions; after the motor 4 is started, under the action of the stirring blade 31, the liquid in the cylinder rotates along the direction of the arrow E to generate centrifugal force, so that the precipitate moves towards the cylinder wall, and meanwhile, a part of the liquid generates a downward movement trend along the rotation direction of the guide plate 2, so that the precipitate is settled to the bottom of the cylinder, and finally, compared with natural settlement, the settling speed and the settling effect are accelerated; after settling for a period of time, pumping out the liquid on the upper layer for further treatment; the sediment can be removed by opening the closure plate 12.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
