[0034] Example 1

[0035] Reference Figure 1-Figure 6The first embodiment of the present application provides a slurry mixing and batching device, including: a stirring tank 10 and a support ring 20. A feeding port 15 is provided on the side wall of the stirring tank 10; the support ring 20 is sleeved on the periphery of the stirring tank 10, and a lifting drive assembly 30 for driving the support ring 20 to lift and move is provided outside the stirring tank 10; wherein, a rotatable positioning ring 90 is provided on the support ring 20, and at least two storage boxes 40 arranged in a ring shape are provided on the positioning ring 90, and the storage box 40 has a accommodating cavity for accommodating materials inside, and the storage box 40 has a material guide pipe 41 at the lower end, and the material guide pipe 41 has a discharge hole 411 connected to the accommodating cavity, and a blocking group capable of blocking the discharge hole 411 is provided in the accommodating cavity. Part 42; A feeding pipe 50 capable of moving along the radial direction of the support ring 20 is provided on the support ring 20, so that the feeding pipe 50 can selectively penetrate the guide pipe 41, and the discharge end of the feeding pipe 50 can penetrate the feeding port 15 and extend into the mixing tank 10, and the feeding pipe 50 has a feeding hole 55 that can be aligned with the discharge hole 411, and a push plate 51 capable of moving along its axial direction is provided in the feeding pipe 50, and the push plate 51 is connected to a baffle 52 extending along the axis of the feeding pipe 50, and when the push plate 51 pushes the material in the feeding pipe 50 to move along the discharge end, the baffle 52 can always block the feed hole 55.

[0036] In this embodiment, the mixing tank 10 has a chamber for accommodating materials, and a main addition port is provided at the upper end of the mixing tank 10, and the main addition port is used to add materials that need to be added in large quantities, such as base materials. The support ring 20 is arranged on the periphery of the mixing tank 10, and the support ring 20 supports it through the lifting drive assembly 30. A rotatable positioning ring 90 is provided on the support ring 20, and the axis of the positioning ring 90 is colinear with the axis of the support ring 20. At least a storage box 40 is provided on the positioning ring 90, and the storage box 40 is provided with an opening for adding materials. A guide pipe 41 is provided at the lower end of the storage box 40, and the guide pipe can penetrate the storage box 40 in the horizontal direction, and the guide pipe 41 can also be provided on the lower end outer wall of the storage box 40. In this embodiment, a solution of hanging a conduit through the storage box 40 is adopted, a discharge hole 411 is provided on the guide tube 41, and a plugging assembly 42 is provided at the discharge hole 411, and the discharge hole 411 is plugged by the plugging assembly 42. Under normal conditions, the discharge hole 411 is in a blocked state. The feed pipe 50 can move laterally, that is, when the positioning ring 90 rotates to a preset position, there is a certain gap between the end of the feed pipe 50 and the storage box 40, so that the positioning ring 90 can rotate normally without interfering with the feed pipe 50. When the positioning ring 90 rotates to align the target storage box 40 with the feeding port 15, the feeding pipe 50 moves radially. At this time, the feeding pipe 50 moves axially along the guide tube 41. When the feeding pipe 50 moves to the feed hole 55 and is aligned with the discharge hole 411, the blocking assembly 42 opens the discharge hole 411, and the material in the storage box 40 enters the feeding pipe 50 through the discharge hole 411 and the feed hole 55 in sequence. Then, the push plate 51 moves axially along the feeding pipe 50 to push the material in the feeding pipe 50 to move, so that the material in the feeding pipe 50 enters the mixing tank 10 through the end of the feeding pipe 50, thereby adding the material. In the above process, the baffle 52 always blocks the feed hole 55, that is, in the process of pushing out the material, the material in the storage box 40 will not continue to enter the feeding pipe 50. When more materials need to be added, the push plate 51 retreats to the initial position, so that the feed hole 55 and the discharge hole 411 are connected again, and the push plate 51 repeatedly pushes the materials in the feeding pipe 50 to move.

[0037] The baffle plate 52 is connected to the push plate 51. When the push plate 51 moves, the baffle plate 52 moves forward with the push plate 51. The length of the baffle plate 52 is long enough. When the push plate 51 moves forward, the baffle plate 52 can always block the feed hole 55. This ensures that when the push plate 51 pushes the material in the feed pipe 50 to move forward, the material in the storage box 40 will not enter the space on the other side of the push plate 51, effectively preventing the material on the other side of the push plate 51 from blocking the push plate 51 from returning to its initial position during the push plate 51's retreat. The space on the other side of the push plate 51 is a clearance space, and the material in it will not be pushed out of the feed pipe 50, which also prevents the material from entering the clearance space and requiring manual cleaning.

[0038] When it is necessary to add the material in another storage box 40 to the mixing tank 10, the feeding pipe 50 retreats to the initial position, the feeding pipe 50 is separated from the storage box 40, and the positioning ring 90 is driven to rotate, so that the target storage box 40 moves to the target position, and the feeding pipe 50 repeats the above operation. By setting a plurality of storage boxes 40, multiple materials can be added at one time, and different materials can be added to the mixing tank 10 at different stages, or the same material can be added to the mixing tank 10 at different stages for multiple times, without the need to repeatedly transport the material from the low end to the high end, and then add the material to the mixing tank 10. It can reduce the labor intensity. The material is added to the mixing tank 10 by means of the storage box 40, the guide tube 41, the feeding pipe 50 and the push plate 51. The storage box 40 can be used to store solid particle materials, solid powder materials, liquid materials, and solid-liquid mixed slurry. The state requirements of the material are low, and the material can be added to the storage box 40 at one time according to the actual use situation, thereby improving its scope of application.

[0041] In this embodiment, the axis extension direction of the feed pipe 50 is the same as the extension direction of the slide 62, and the feed pipe 50 is horizontally placed on the support block 60, and the feed pipe 50 can be connected by welding, bonding or by a bolt assembly. The cross-sectional shape of the slider 61 is a dovetail or T-shaped, and the slide 62 is a dovetail groove or T-shaped groove that matches the shape of the slider 61. An oil cylinder, an air cylinder or an electric push rod can be arranged on the support ring 20, and the telescopic end of the oil cylinder, the air cylinder or the electric push rod is interconnected with the support block 60 to drive the support block 60 to reciprocate. A transmission system with the same working principle as the lifting drive assembly 30 can also be arranged on the support ring 20 to drive the support block 60 to reciprocate.

[0042] Example 3

[0043] As an optional implementation, refer to Figure 1 and Figure 6The present embodiment provides a specific structure for driving the positioning ring 90 to rotate, including: a first motor 95 is arranged on the support ring 20, a driving wheel 94 is arranged on the output shaft of the first motor 95, an annular ring gear 93 is arranged on the positioning ring 90, the driving wheel 94 is meshed with the ring gear 93, a limiting groove 92 extending along the circumferential direction is arranged on the support ring 20, and a limiting block 91 for cooperating with the limiting groove 92 is arranged on the positioning ring 90.

[0044] In the present embodiment, by setting the limit groove 92 and the limit block 91, the movement of the positioning ring 90 is guided by the limit, and the situation that the positioning ring 90 moves laterally is reduced. The cross-sectional shape of the limit block 91 can be hemispherical. The positioning ring 90 is driven to rotate by the way of the gear ring 93 and the driving wheel 94, and the stability of the rotation of the positioning ring 90 is improved. The first motor 95 can be a stepper motor or a servo motor. According to the number of the storage boxes 40 set on the positioning ring 90, the angle of the single rotation of the positioning ring 90 can be controlled. For example, the ring array on the positioning ring 90 is provided with 6 storage boxes 40, and the center angle corresponding to the adjacent storage boxes 40 is 60°. The angle of the single rotation of the positioning ring 90 is 60°, so as to ensure that the positioning ring 90 can make the storage box 40 in the target position each time it rotates, and the target position is the position aligned with the feeding port 15.

[0045] Example 4

[0046] As an optional implementation, refer to Figure 3-Figure 4 This embodiment provides a specific structure of a sealing component 42, including: the sealing component 42 includes a fixed frame 421, a first spring 422 and a sealing core 423; the fixed frame 421 is arranged above the discharge hole 411, the sealing core 423 can seal the discharge hole 411, and the first spring 422 is arranged between the sealing core 423 and the fixed frame 421.

[0047] Optionally, a lifting assembly 70 is provided at the feed hole 55, and the lifting assembly 70 includes a lifting block 72 and an elastic member 71. One end of at least one elastic member 71 is connected to the inner wall of the feed hole 55, and the other end is connected to the lifting block 72. The lifting block 72 can selectively protrude out of the feed hole 55 to lift the sealing core 423 and move it in a direction away from the discharge hole 411. The cross-sectional area of ​​the discharge hole 411 gradually decreases in the direction away from the feed hole 55.

[0048] In this embodiment, the plugging core 423 has a stepped shape, and the plugging core 423 always has a tendency to move toward the discharge hole 411 under the action of the first spring 422. In the initial state, the plugging core 423 can always block the discharge hole 411, and the discharge hole 411 can be located directly above or on the side wall of the guide tube 41. It should be noted that the upper end of the plugging core 423 is an arc-shaped surface, which reduces the resistance of the plugging core 423 to move upward. Further, in order to reduce the pressure on the plugging core 423 to move upward, the upper end of the plugging core 423 can be set as a long rod, and the upper end of the long rod passes through the upper end of the storage box 40 to reduce the pressure of the material in the storage box 40 on the plugging core 423, so that the valve core can move upward smoothly and leave the discharge hole 411. By arranging the lifting assembly 70 at the feed hole 55 of the feed pipe 50, when the feed pipe 50 moves along the guide pipe 41, the lifting block 72 moves downward under the force of the outer wall of the guide pipe 41, and the elastic member 71 undergoes elastic deformation. When the feed pipe 50 moves to the position where the feed hole 55 is aligned with the discharge hole 411, the lifting block 72 automatically moves upward under the action of the elastic member 71, at which time the lifting block 72 abuts against the plugging core 423 and drives the plugging core 423 to move upward, the plugging core 423 is separated from the discharge hole 411, and the discharge hole 411 is connected with the feed hole 55, and the material in the storage box 40 enters the feed pipe 50 through the discharge hole 411 and the feed hole 55. When the feeding pipe 50 moves backward, the lifting block 72 is separated from the blocking core 423, and the blocking core 423 automatically moves downward under the action of the first spring 422 to block the discharge hole 411, thereby preventing the material in the storage box 40 from leaking out of the discharge hole 411. The lifting block 72 is hemispherical, and the aperture of the discharge hole 411 gradually decreases in the direction away from the feeding hole 55, so that the material will not be stuck on the inner wall of the discharge hole 411, and the inner wall of the discharge hole 411 can guide the lifting block 72, so that the elastic member 71 undergoes elastic deformation, and the lifting block 72 moves out of the discharge hole 411.

[0049] Example 5

[0050] As an optional implementation, refer to Figure 2-Figure 3 This embodiment provides a specific structure for driving the push plate 51 to move, including: the push plate 51 is connected to a connecting rod 53 that axially penetrates the outer wall of the feeding tube 50, and a hydraulic cylinder 54 is provided on the outer wall of the feeding tube 50, and the telescopic end of the hydraulic cylinder 54 is connected to the connecting rod 53.

[0051] In this embodiment, the first end of the connecting rod 53 is connected to the push plate 51, the second end of the connecting rod 53 passes through the outer wall of the feeding pipe 50, the telescopic shaft of the hydraulic cylinder 54 is connected to the second end of the connecting rod 53, and the hydraulic cylinder 54 is arranged on the outer wall of the feeding pipe 50, that is, the hydraulic cylinder 54 moves laterally synchronously with the feeding pipe 50.

[0052] Example 6

[0054] In this embodiment, by providing the second spring 82, the stop ring 83 and the pull rod 81, a pulling force is applied to the fixed plate 80, so that the fixed plate 80 always has a tendency to move toward the discharge port. In the initial state, the fixed plate 80 is always in a state of blocking the discharge port. At this time, the volume of the space between the push plate 51 and the fixed plate 80 in the feeding pipe 50 is fixed, and the volume of the material entering the above space can also be calculated. When the material enters the space between the push plate 51 and the fixed plate 80, the fixed plate 80 is always in a state of blocking the discharge port. The push plate 51 pushes the material in the above space to move in the direction close to the fixed plate 80. When the material in the above space cannot be compressed, the push plate 51 pushes the fixed plate 80 to move forward, the fixed plate 80 is separated from the discharge port, and the material enters the internal space of the mixing tank 10 from the discharge port. When the material in the feeding pipe 50 is completely discharged, the push plate 51 retreats, and the fixed plate 80 moves toward the discharge port under the action of the second spring 82, and finally the fixed plate 80 blocks the discharge port.

The weight of the material storage box 40 can be obtained by the weighing sensor, and the weight of the material discharged by the material storage box 40 can be obtained by obtaining the weight reduction of the material storage box 40, so as to more accurately control the amount of material added to the mixing tank 10. Similarly, the weight reduction of the material storage box 40 can be obtained after the push plate 51 pushes the material once, and the weight of the material discharged by the push plate 51 can be obtained, so as to calculate the weight of the material discharged once when different types of materials are added. The two can be calibrated with each other, so as to remind the maintenance personnel to troubleshoot the problem when large deviations occur continuously.
