Description

Technical Field

[0001] The invention relates to the technical field of ceramic raw material preparation, and in particular to a fully mixed ceramic slurry slurry pouring and mixing system and method. Background Art

[0002] The standardized preparation of ceramic raw materials is a common problem that needs to be solved in the building ceramics industry. In the process of preparing ceramic raw materials, the homogenization and mixing process of the slurry has an important impact on the standardized preparation of raw materials. The mixing method and mixing time directly affect the stability of the slurry performance, and thus affect the quality of the finished tiles.

[0003] In the prior art, ceramic slurry is mostly mixed in a single tank. This mixing method is suitable for small-capacity ceramic production lines. The mixing method is single and the slurry in the tank is easy to settle, making the slurry uneven, resulting in unstable slurry performance, and ultimately leading to uneven quality of ceramic products. Summary of the invention

[0004] In view of the above shortcomings, the present invention provides a fully mixed ceramic slurry slurry pouring and mixing system, which can solve the problem of poor mixing effect in a single tank.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme:

[0006] A fully mixed ceramic slurry slurry mixing system includes at least two groups of slurry mixing pools, each of which includes more than two slurry mixing pools and a slurry mixing feed pipe and a first slurry mixing main pipe. The slurry mixing feed pipe is connected to at least one of the slurry mixing pools in the same group. Each of the slurry mixing pools is connected to the first slurry mixing main pipe in the same group through a pipeline, and the connected pipelines are provided with a first automatic switch for cutting off or conducting the pipeline; every two first slurry mixing main pipes are connected through a pipeline pump.

[0007] Furthermore, each group of the mixing tank group also includes a second reverse pulp main pipe, which is connected to each mixing tank of the same group through a branch pipe, and each branch pipe is provided with a second automatic switch for cutting off or conducting the branch pipe;

[0008] The second slurry return main pipe is connected to the bottom of each slurry mixing tank of the same group through a liquid extraction pipe, and each of the liquid extraction pipes is provided with a third pipeline pump and a third automatic switch for cutting off or conducting the liquid extraction pipe.

[0009] Furthermore, a slurry outlet pipe is provided at the bottom of each of the mixing tanks, and a fourth automatic switch for cutting off or connecting the slurry outlet pipe is provided on the slurry outlet pipe.

[0010] Furthermore, there are two pipeline pumps between every two first slurry main pipes, namely the first pipeline pump and the second pipeline pump. The first pipeline pump and the second pipeline pump are both single-stage centrifugal pumps that can only pump liquid in one direction. The pumping directions of the first pipeline pump and the second pipeline pump between every two first slurry main pipes are opposite.

[0011] Furthermore, the first automatic switch, the second automatic switch, the third automatic switch and the fourth automatic switch are electric valves, pneumatic valves or solenoid valves.

[0012] Furthermore, a control system is included, and the first automatic switch, the second automatic switch, the third automatic switch, the fourth automatic switch, the first pipeline pump, the second pipeline pump and the third pipeline pump are respectively electrically connected to the control system and controlled by the control system.

[0013] Furthermore, each of the mixing pools is provided with a stirring paddle, and at least two groups of propellers are installed on the stirring paddle, each group of propellers includes a plurality of spiral blades evenly distributed around the circumference, and the spiral blades have the same shape. The leading edge of the spiral blade is a convex arc surface, and the trailing edge is a concave arc surface. The bottom surface of the blade is gradually bent upward from the center to the outside to form an arc-shaped outer contour.

[0014] The present invention also provides a method for slurry mixing of a fully mixed ceramic slurry, which uses the above-mentioned slurry mixing system for slurry mixing of a fully mixed ceramic slurry, and comprises the following steps:

[0016] S2, the slurry mixing pool group that enters the slurry performs internal slurry mixing and then moves to other slurry mixing pool groups to perform inter-group slurry mixing;

[0017] S3. Each group of slurry mixing tanks conducts internal slurry mixing and inter-group slurry mixing, and the slurry is discharged after a certain number of slurry mixing.

[0018] Furthermore, in the above-mentioned method for pouring and mixing the fully mixed ceramic slurry, the intra-group pouring and mixing performed by each group of mixing pools is pouring and mixing one or more mixing pools in the group into one or more mixing pools in the same group.

[0019] Furthermore, in the above-mentioned method for pouring and mixing the fully mixed ceramic slurry, the inter-group pouring and mixing of the mixing pool groups is pouring and mixing one or more mixing pools of the same group into one or more mixing pools of other groups.

[0037] The pipeline connecting each slurry mixing tank and the first slurry reverse pipe 21 of the same group is provided with a first automatic switch 23 for cutting off or conducting the pipeline, and the first automatic switch 23 is a solenoid valve. The two first slurry reverse pipes 21 are connected by a pipeline pump, and there are two pipeline pumps, namely, a first pipeline pump 24 and a second pipeline pump 25, that is, the two first slurry reverse pipes 21 are connected by the first pipeline pump 24 and the second pipeline pump 25, and the first pipeline pump 24 and the second pipeline pump 25 are preferably single-stage centrifugal pumps that can only pump liquid in one direction. The first pipeline pump 24 and the second pipeline pump 25 between the two first slurry reverse pipes 21 have opposite pumping directions. In this preferred embodiment, the first pipeline pump 24 is in the form of pumping liquid from the A group slurry mixing tank group to the B group slurry mixing tank group, and the second pipeline pump 25 is in the form of pumping liquid from the B group slurry mixing tank group to the A group slurry mixing tank group.

[0038] In this preferred embodiment, each group of mixing tanks further includes a second reverse pulping main pipe 26, which is connected to the top of each mixing tank in the same group through a branch pipe 27, that is, the second reverse pulping main pipe 26 of the mixing tank group A is connected to the top of the first mixing tank A11, the second mixing tank A12, the third mixing tank A13, and the fourth mixing tank A14 through a branch pipe 27, and the second reverse pulping main pipe 26 of the mixing tank group B is connected to the top of the fifth mixing tank B11, the sixth mixing tank B12, the seventh mixing tank B13, and the eighth mixing tank B14 through a branch pipe 27.

[0039] The second reverse slurry main pipe 26 is connected to the bottom of each mixing tank of the same group through the liquid extraction pipe 29, that is, the second reverse slurry main pipe 26 of the mixing tank group A is connected to the bottom of the first mixing tank A11, the second mixing tank A12, the third mixing tank A13, and the fourth mixing tank A14 through the liquid extraction pipe 29, and the second reverse slurry main pipe 26 of the mixing tank group B is connected to the bottom of the fifth mixing tank B11, the sixth mixing tank B12, the seventh mixing tank B13, and the eighth mixing tank B14 through the liquid extraction pipe 29. Each liquid extraction pipe 29 is provided with a third pipeline pump 210 and a third automatic switch 211 for cutting off or conducting the liquid extraction pipe. The third pipeline pump 210 is preferably a single-stage centrifugal pump that can only extract liquid in one direction, so that the slurry can be transported from each mixing tank through the liquid extraction pipe 29 to the second reverse slurry main pipe 26 through the third pipeline pump 210. The third automatic switch 211 is a solenoid valve, which can prevent the slurry from flowing back from the second slurry backflow main pipe 26 through the liquid extraction pipe 29 into the slurry mixing tank.

[0040] Furthermore, a slurry outlet pipe 212 is provided at the bottom of each mixing tank, that is, a slurry outlet pipe 212 is provided at the bottom of the first mixing tank A11, the second mixing tank A12, the third mixing tank A13, the fourth mixing tank A14, the fifth mixing tank B11, the sixth mixing tank B12, the seventh mixing tank B13, and the eighth mixing tank B14, and a fourth automatic switch 213 for cutting off or conducting the slurry outlet pipe 212 is provided on the slurry outlet pipe 212, and a solenoid valve is selected for the fourth automatic switch 213. By opening the fourth automatic switch 213 corresponding to each mixing tank, the slurry outlet pipe 212 on it is conducted, and the slurry can be discharged through the slurry outlet pipe 212, and the discharged slurry can be transported to the spray drying tower through a pipeline for spray drying.

[0041] In a preferred embodiment, the fully mixed ceramic slurry slurry mixing system of the present invention also includes a control system, and the first automatic switch 23, the second automatic switch 28, the third automatic switch 211, the fourth automatic switch 213, the first pipeline pump 24, the second pipeline pump 25 and the third pipeline pump 210 are respectively electrically connected to the control system and controlled by the control system, so as to be uniformly coordinated and controlled by the control system. The control system can be a separately set control system, or a central control module of the plant can be used to achieve unified scheduling. In a preferred embodiment, each mixing pool is provided with a liquid level sensor for detecting the liquid level in the mixing pool, that is, the first mixing pool A11, the second mixing pool A12, the third mixing pool A13, the fourth mixing pool A14 and the fifth mixing pool B11, the sixth mixing pool B12, the seventh mixing pool B13, and the eighth mixing pool B14 are all provided with liquid level sensors, and the liquid level sensor is electrically connected to the control system and transmits the detection signal to the control system, so that when the liquid level in each mixing pool reaches the upper limit liquid level, the control system can control the first automatic switch 23 and / or the second automatic switch 28 and / or the third automatic switch 211 and / or the fourth automatic switch 213 connected to each mixing pool to realize liquid level control, such as timely stopping of slurry feeding or timely discharge, etc., to prevent excessive liquid level.

[0042] During implementation, the fully mixed ceramic slurry pouring and mixing system of this preferred embodiment can perform inter-group pouring and mixing between the mixing pool groups, and the mixing pool groups can also perform intra-group pouring and mixing between the mixing pools.

[0043] The following uses the reverse slurry mixing between the mixing pool group A and the mixing pool group B to illustrate the reverse slurry mixing mode between the mixing pool groups. The reverse slurry mixing between the first mixing pool A11 in the mixing pool group A and the fifth mixing pool B11 in the mixing pool group B is taken as a specific example. During implementation, the first automatic switch 23 on the pipeline connecting the first mixing pool A11 and the fifth mixing pool B11 with the first reverse slurry main pipe 21 of the same group is turned on, and the corresponding pipeline is in a conducting state, while the first automatic switch 23 on the pipeline connecting the second mixing pool A12, the third mixing pool A13, the fourth mixing pool A14, the sixth mixing pool B12, the seventh mixing pool B13 and the eighth mixing pool B14 with the first reverse slurry main pipe 21 of the same group is turned off, and the corresponding pipeline is in a cut-off state. In this state, the second pipeline pump 25 is turned off, and the first pipeline pump 24 is started. The two first slurry reverse main pipes 21 are connected through the first pipeline pump 24, and at this time only the first automatic switches 23 corresponding to the first mixing pool A11 in the mixing pool group of group A and the fifth mixing pool B11 in the mixing pool group of group B are turned on, then the slurry in the first mixing pool A11 in the mixing pool group of group A can be pumped into the fifth mixing pool B11 in the mixing pool group of group B through the first pipeline pump 24 to achieve inter-group slurry reverse mixing; correspondingly, the first pipeline pump 24 is turned off, and the second pipeline pump 25 is started. At this time, the slurry in the fifth mixing pool B11 in the mixing pool group of group B can be pumped into the first mixing pool A11 in the mixing pool group of group A through the second pipeline pump 25 to achieve inter-group slurry reverse mixing. Similarly, when the first automatic switch 23 corresponding to one or more mixing pools in each group of mixing pools is opened or closed accordingly, one or more mixing pools in one group of mixing pools can be transferred to one or more mixing pools in another group of mixing pools for mixing. This method is used to mix the slurry between the groups of mixing pools. This method does not limit the number of mixing pools that are mixed with each other. Through the coordinated control of the first automatic switch 23 corresponding to each mixing pool and the first pipeline pump 24 and the second pipeline pump 25, the slurry from multiple pools can be pumped into a single pool for mixing, and the slurry from a single pool can be pumped into multiple pools for mixing, so as to achieve the purpose of continuous cross mixing between the groups.

[0044] The following uses the inverted slurry mixing between the mixing pools of the A group mixing pool group to illustrate the inverted slurry mixing mode between the mixing pools in the mixing pool group. Taking the inverted slurry mixing between the first mixing pool A11 and the second mixing pool A12 in the A group mixing pool group as a specific example, the third automatic switch 211 on the liquid extraction pipe 29 corresponding to the first mixing pool A11 is turned on, the third automatic switch 211 on the liquid extraction pipe 29 corresponding to the second mixing pool A12, the third mixing pool A13, and the fourth mixing pool A14 is turned off, and the second automatic switch 28 on the branch pipe 27 corresponding to the second mixing pool A12 is turned on, the second automatic switch 28 on the branch pipe 27 corresponding to the first mixing pool A11, the third mixing pool A13, and the fourth mixing pool A14 is turned off, and the third pipeline pump 210 on the liquid extraction pipe 29 corresponding to the first mixing pool A11 is started. At this time, only the second automatic switch 28 corresponding to the second mixing pool A12 is turned on, then the slurry in the first mixing pool A11 can be pumped through the first mixing pool A11. The slurry is pumped into the second reverse slurry main pipe 26 through the third pipeline pump 210 and then enters the second mixing tank A12 through the branch pipe 27 corresponding to the second mixing tank A12 and the second automatic switch 28 to achieve reverse slurry mixing within the group; accordingly, the second automatic switch 28 on the branch pipe 27 corresponding to the second mixing tank A12 is closed, the second automatic switch 28 corresponding to the first mixing tank A11 is closed, the third automatic switch 211 on the liquid extraction pipe 29 corresponding to the second mixing tank A12 is opened, the third automatic switch 211 corresponding to the first mixing tank A11 is closed, and the third pipeline pump 210 on the liquid extraction pipe 29 corresponding to the second mixing tank A12 is started. At this time, only the second automatic switch 28 corresponding to the first mixing tank A11 is opened, and the slurry in the second mixing tank A12 can be pumped into the second reverse slurry main pipe 26 through the third pipeline pump 210 and then enter the first mixing tank A11 through the branch pipe 27 and the second automatic switch 28 corresponding to the first mixing tank A11 to achieve reverse slurry mixing within the group. Similarly, when the corresponding second automatic switch 28 and the third automatic switch 211 in each group of mixing pools are opened or closed accordingly, one or more mixing pools in the same group of mixing pools can be transferred to one or more mixing pools in the same group of mixing pools. The same group of mixing pools are all transferred to the same group in this way. This method does not limit the number of mixing pools that are transferred to each other. Through the coordinated control of the second automatic switch 28 and the third automatic switch 211 corresponding to each mixing pool and the third pipeline pump 210, the slurry in multiple pools can be pumped into a single pool for transfer and mixing, and the slurry in a single pool can also be pumped into multiple pools for transfer and mixing, so as to achieve the purpose of continuous cross mixing within the group.

[0045] In a preferred embodiment of the present invention, the inter-group slurry mixing between the groups of mixing pools and the intra-group slurry mixing between the mixing pools in the mixing pool group can be performed simultaneously.

[0046] This preferred embodiment also provides a method for slurry mixing of a fully mixed ceramic slurry, using the above-mentioned slurry mixing system for slurry mixing of a fully mixed ceramic slurry, comprising the following steps:

[0047] S1, feeding slurry into two groups of slurry mixing tanks through the slurry mixing feed pipe;

[0048] S2, the slurry mixing pool group that enters the slurry performs internal slurry mixing and then moves to other slurry mixing pool groups to perform inter-group slurry mixing;

[0049] The slurry mixing within each group of slurry mixing tanks is performed by pouring slurry from one or more slurry mixing tanks within the group to one or more slurry mixing tanks in the same group;

[0050] The inter-group slurry mixing of each group of slurry mixing tanks is to mix the slurry from one or more slurry mixing tanks of the same group to one or more slurry mixing tanks of other groups;

[0051] The slurry mixing within the group and the slurry mixing between the groups can be performed multiple times, either the slurry mixing within the group and the slurry mixing between the groups can be performed multiple times continuously, or the slurry mixing within the group and the slurry mixing between the groups can be performed multiple times alternately.

[0052] S3. Each group of slurry mixing tanks conducts internal slurry mixing and inter-group slurry mixing, and the slurry is discharged after a certain number of slurry mixing.

[0053] The following is a more specific embodiment to illustrate the fully mixed ceramic slurry pouring and mixing method of the present invention. Figure 6 , specifically including the following steps:

[0054] The slurry from ball mill B enters the fifth slurry mixing tank B11 and the sixth slurry mixing tank B12 in the slurry mixing tank group of group B through the slurry mixing feed pipe 20; the slurry from ball mill A enters the first slurry mixing tank A11 and the second slurry mixing tank A12 in the slurry mixing tank group of group A through the slurry mixing feed pipe 20;

[0055] The fifth mixing tank B11 and the sixth mixing tank B12 are equipped with motors to drive the stirring paddle 214 to mix the slurry once; after mixing for a period of time, the slurry in the fifth mixing tank B11 and the sixth mixing tank B12 is pumped into the seventh mixing tank B13 and the eighth mixing tank B14 through the inverted slurry mixing method within the group for secondary mixing. At this time, the slurry in the fifth mixing tank B11 and the sixth mixing tank B12 is mixed in the seventh mixing tank B13 and the eighth mixing tank B14, and at the same time, the slurry in the ball mill B is continuously transported to the fifth mixing tank B11 and the sixth mixing tank B12 for replenishment;

[0056] At the same time, the first mixing tank A11 and the second mixing tank A12 are equipped with motors to drive the stirring paddle 214 to mix the slurry once; after mixing for a period of time, the slurries in the first mixing tank A11 and the second mixing tank A12 are pumped into the third mixing tank A13 and the fourth mixing tank A14 through the inverted slurry mixing method within the group for secondary mixing. At this time, the slurry A in the first mixing tank A11 and the second mixing tank A12 is mixed in the third mixing tank A13 and the fourth mixing tank A14, and at the same time, the slurry in the ball mill A is continuously transported to the first mixing tank A11 and the second mixing tank A12 for replenishment;

[0057] After the slurry in the seventh mixing tank B13 and the eighth mixing tank B14 is mixed independently for a period of time, the slurry in the seventh mixing tank B13 and the eighth mixing tank B14 is pumped into the first mixing tank A11, the second mixing tank A12, the third mixing tank A13 and the fourth mixing tank A14 of the mixing tank group of group A through the inter-group inversion mixing method, and is mixed with the slurry in the first mixing tank A11, the second mixing tank A12, the third mixing tank A13 and the fourth mixing tank A14 of the mixing tank group of group A, and the slurry in the first mixing tank A11, the second mixing tank A12, the third mixing tank A13 and the fourth mixing tank A14 of the mixing tank group of group A is mixed three times independently;

[0058] After the slurry in the third mixing tank A13 and the fourth mixing tank A14 is mixed independently for a period of time, the slurry in the third mixing tank A13 and the fourth mixing tank A14 is pumped into the fifth mixing tank B11, the sixth mixing tank B12, the seventh mixing tank B13 and the eighth mixing tank B14 of the mixing tank group of group B through the inter-group inversion mixing method, and is mixed with the slurry in the fifth mixing tank B11, the sixth mixing tank B12, the seventh mixing tank B13 and the eighth mixing tank B14 of the mixing tank group of group B, and the slurry in the fifth mixing tank B11, the sixth mixing tank B12, the seventh mixing tank B13 and the eighth mixing tank B14 of the mixing tank group of group B is mixed independently for three times;

[0059] The three mixings can be performed only once or multiple times. After the three mixings, the slurry in the first mixing tank A11 and the second mixing tank A12 is simultaneously pumped into the third mixing tank A13 and the fourth mixing tank A14 in the form of inverted slurry mixing within the group for four mixings. Similarly, the slurry in the fifth mixing tank B11 and the sixth mixing tank B12 is simultaneously pumped into the seventh mixing tank B13 and the eighth mixing tank B14 in the form of inverted slurry mixing within the group for four mixings. Finally, the slurry in the ball mill A and the ball mill B is discharged into the spray drying tower through the slurry outlet pipes 212 of the third mixing tank A13 and the fourth mixing tank A14 and the seventh mixing tank B13 and the eighth mixing tank B14 for spray drying after multiple inverted slurry mixing, that is, the slurry is discharged after a certain number of inverted slurry mixing.

[0060] Among them, in the above-mentioned preferred implementation method, the slurry in ball mill A and ball mill B is the same slurry; the intra-group slurry mixing of the A mixing pool group and the B mixing pool group can be carried out simultaneously, and the inter-group slurry mixing between the A mixing pool group and the B mixing pool group is carried out alternately, and the work does not affect each other; the slurry discharge amount of each branch outlet of the first slurry discharge main pipe 21 and the second slurry discharge main pipe 26 is equal; the slurry discharge amount of the slurry outlet pipe 212 of the third mixing pool A13 and the fourth mixing pool A14 and the seventh mixing pool B13 and the eighth mixing pool B14 is equal; the stirring paddle 214 in each mixing pool is in a continuous stirring state driven by a motor.

[0061] The fully mixed ceramic slurry slurry pouring and mixing system of the present invention, by setting up multiple groups of mixing pools, allows the slurries on multiple production lines to be cross-mixed, saving layout space and improving the effect of slurry homogenization; through the multi-pool mixing method, the slurry flow can be increased, and the slurry sedimentation can be prevented, so that the slurry is uniform and the performance is stable, so as to ensure the excellent and uniform quality of ceramic products; by setting up multiple mixing pools, both intra-group mixing and slurry pouring can be achieved, and inter-group mixing and slurry pouring can be achieved, and continuous and large-scale mixed slurry can be achieved; at the same time, suitable mixing routes can be designed according to different slurry discharge requirements, and a combination of multiple routes can be achieved to achieve the purpose of slurry homogenization.
