[0033] This invention provides a slurry mixing and anti-settling device, such as... Figures 1 to 3 As shown.

[0034] In one exemplary embodiment of this application, a slurry mixing and anti-settling device is provided, comprising:

[0035] The housing 2 has a cover 3 on it, and the cover 3 and the housing 2 have an open state and a closed state. A support rod 701 is provided next to the housing 2.

[0036] A mixing container 8 is located inside the shell 2 and is used to hold the slurry;

[0037] The stirring mechanism 5 is movably mounted on the support rod 701 and is used to enter the stirring container 8 in the open state to stir the slurry;

[0038] The defoaming component 4 is installed on the cover 3 and is used to defoam the slurry when the cover is closed.

[0039] In use, open the cover 3 so that the shell 2 and the cover 3 are in the open state, pour the slurry into the mixing container 8, and adjust the position of the stirring mechanism 5 to stir the slurry in the mixing container 8. After stirring is completed, remove or take out the stirring mechanism 5, then close the cover 3 so that the cover 3 and the shell 2 are in the closed state, and then operate the defoaming component 4 to defoam.

[0040] In this embodiment, the shell 2 and the cover 3 are provided to form a closed space after mixing, facilitating defoaming. The support rod 701 is provided to facilitate the installation of the mixing mechanism 5. The mixing mechanism 5 is provided to facilitate the mixing of the slurry. The mixing mechanism 5 can move up and down along the support rod 701 to adjust its height and perform lifting and lowering operations. The mixing container 8 is provided to hold the slurry.

[0041] For example, a base 1 is provided at the bottom of the housing 2, and the support rod 701 is fixedly connected to the base 1 to facilitate the overall movement of the slurry mixing and anti-settling equipment.

[0042] In one exemplary embodiment, a slide rail 201 is provided at the bottom of the housing 2, and the stirring container 8 is slidably mounted on the slide rail 201.

[0043] In this embodiment, the slide rail 201 is provided to facilitate the adjustment of the position of the stirring container 8.

[0044] In one exemplary embodiment, a fixing buckle 202 for fixing the stirring container 8 is provided on the slide rail 201.

[0045] In this embodiment, the fixing buckle 202 is provided to fix the mixing container 8 after it is adjusted into place, so as to prevent the mixing container 8 from moving during the mixing process.

[0046] It should be noted that the stirring container 8 can be limited by a limiting insert that can be inserted into the slide rail 201, or it can be a fixing buckle 202 (or clip) that can be clamped on the slide rail 201.

[0047] In an exemplary embodiment, the stirring mechanism 5 includes a control box 501, which is allowed to move up and down on a support rod 701. A stirring rod 502 is disposed below the control box 501, and a stirring paddle 503 is disposed at one end of the stirring rod 502 away from the control box 501.

[0048] For example, a motor is installed inside the control box 501, and the output end of the motor is connected to the stirring rod 502. The stirring rod 502 is driven to rotate by the rotation of the motor, thereby realizing the stirring of the slurry.

[0049] For example, the stirring rod 502 is detachably connected to the output end of the motor to facilitate the installation and replacement of the stirring paddle 503.

[0050] For example, the stirring rod 502 is keyed, snap-fitted, or screwed to the output shaft of the motor.

[0051] For example, the control box 501 is equipped with a control panel and a display panel. The display panel displays parameters such as motor speed and time. The control panel is used to control the operation of the motor, etc.

[0052] In one exemplary embodiment, a cover 602 is provided on the stirring rod 502, which is used to cover the opening on the stirring container 8.

[0053] It should be noted that the shielding cover 602 is designed to prevent the slurry from splashing out and causing waste during the mixing process.

[0054] In an exemplary embodiment, a telescopic mechanism is provided inside the control box 501. The bottom end of the telescopic mechanism is connected to a cover 602, and a through hole is provided in the middle of the cover 602 for the stirring rod 502 to pass through.

[0055] In this embodiment, the telescopic mechanism is provided to facilitate adjustment of the position of the cover 602 according to the size and height of the mixing container 8. The through hole on the cover 602 allows the stirring rod 502 to pass through, preventing the cover 602 from shifting position during mixing and affecting the blocking effect.

[0056] For example, the telescopic mechanism can be a pneumatic cylinder or a hydraulic cylinder. The output end of the telescopic mechanism is provided with a mounting rod 601. The mounting rod 601 is connected to the cover 602. The mounting rod 601 is detachably connected to the telescopic mechanism so that the cover 602 can be changed according to the size of the mixing container 8.

[0057] For example, the mounting rod 601 is keyed, plugged in, or snapped into the telescopic mechanism.

[0058] It should be noted that the cover 602 and the stirring rod 502 are fitted with a gap to prevent the cover 602 from moving during the stirring process.

[0059] In an exemplary embodiment, the defoaming assembly 4 includes a defoaming pipe 401 disposed on the cover 3. One end of the defoaming pipe 401 is an external connection port, and the other end of the defoaming pipe 401 is connected to a vacuum pump. The middle part of the defoaming pipe 401 is a connection point that communicates with the interior of the cover 3. A venting valve 402 is disposed between the connection point and the external connection port, and a working valve 404 is disposed between the connection point and the vacuum pump.

[0060] For example, a pressure gauge 403 is provided at the connection point for pressure detection within the housing 2.

[0061] In use, after removing the stirring mechanism 5, place the cover 3 on the housing 2, then open the working valve 404 and close the vent valve 402 to start the vacuum pump. The pressure inside the housing 2 is detected by the pressure gauge 403 and displayed on the display panel for the operator to view. When the detected pressure reaches the preset value, a timer begins, and the vacuum pump stops working after the preset time has elapsed to end the degassing process. Afterwards, close the working valve 404 and slowly open the vent valve 402 until the detected pressure is zero, at which point subsequent operations such as opening the cover 3 can be performed.

[0062] In this embodiment, defoaming and stirring are performed using the same equipment, which is low-cost and eliminates the need to move the slurry after stirring. Moving the slurry may cause slurry loss or generate bubbles.

[0063] In an exemplary embodiment, the support rod 701 is arranged in the vertical direction, and a connecting rod 702 is provided on the support rod 701. The connecting rod 702 is arranged in the horizontal direction, and the stirring mechanism 5 is arranged on the connecting rod 702. The connecting rod 702 and the support rod 701 are connected by a movable seat, so that the connecting rod 702 can move up and down along the support rod 701.

[0064] In this embodiment, the movable seat and connecting rod 702 are provided to facilitate the adjustment of the position of the stirring mechanism 5, that is, the position of the stirring mechanism 5 can be adjusted in the vertical direction.

[0065] In an exemplary embodiment, the movable seat is provided with a mounting hole and a mounting groove, the support rod 701 passes through the mounting hole, the connecting rod 702 is installed in the mounting groove, and the movable seat is also provided with a first locking member 704 for locking the support rod 701 and a second locking member 705 for locking the connecting rod 702.

[0066] In this embodiment, the mounting groove on the movable seat and the second locking member 705 enable the stirring mechanism 5 to be adjusted not only in the horizontal direction, but also the connecting rod 702 to be removed from the movable seat so that the stirring mechanism 5 can be taken out of the housing 2.

[0067] In addition, the mounting hole and the first locking member 704 allow the connecting rod 702 to rotate about the support rod 701 as a rotation axis to adjust its position.

[0068] For example, both the first locking member 704 and the second locking member 705 include a threaded rod for threaded engagement with the connecting seat 703.

[0069] In an exemplary embodiment of this application, a slurry mixing anti-settling method is also provided, applied to a slurry mixing anti-settling device, the method including steps S100 to S500.

[0070] S100, switch the cover 3 and the housing 2 to the open state.

[0071] In this embodiment, the cover 3 is opened to facilitate the placement of the slurry and to facilitate subsequent stirring by the stirring mechanism 5.

[0072] S200, put the slurry into the mixing container 8.

[0073] It should be noted that the mixing container 8 can be placed inside the shell 2 first, and then the slurry can be poured into the mixing container 8. Alternatively, the slurry can be poured into the mixing container 8 first, and then the mixing container 8 can be placed inside the shell 2.

[0074] S300, adjust the position of the stirring mechanism 5 so that the stirring mechanism 5 can stir the slurry in the stirring container 8.

[0075] In this embodiment, the stirring mechanism 5 can move vertically and horizontally to adapt to the position of the stirring container 8. The stirring by the stirring mechanism 5 prevents the slurry from settling.

[0076] S400, remove the stirring mechanism 5 and switch the cover 3 and the shell 2 to the closed state.

[0077] In this embodiment, after stirring is completed, the stirring mechanism 5 needs to be removed so that the cover 3 can be put on.

[0078] For example, the stirring mechanism 5 can be removed directly or moved out of the housing 2 by adjusting its position.

[0079] S500 controls the defoaming component 4 to defoam.

[0080] In this embodiment, the defoaming component 4 is installed on the cover 3. After the stirring mechanism 5 is removed, the cover 3 can be closed to achieve the defoaming operation. The entire process does not require moving the stirring container 8 and the slurry. Compared with using two separate sets of equipment for stirring and defoaming, the required cost is low and the generation of bubbles caused by moving the slurry can be effectively reduced.

[0081] In an exemplary embodiment, controlling the defoaming component 4 to defoam includes steps S510 to S550.

[0082] Step S510: Open the working valve 404 and close the vent valve 402.

[0083] In this embodiment, the working valve 404 is a valve on the degassing pipe 401 that controls the connection between the vacuum pump and the inside of the housing 2, and the vent valve 402 is a valve between the degassing pipe 401 and the outside. When the vent valve 402 is closed, the degassing pipe 401 is no longer connected to the outside, and the working valve 404 is opened to facilitate subsequent evacuation operations.

[0084] Step S520: Perform the air extraction operation.

[0085] In this embodiment, a vacuum pump is used for evacuation.

[0086] Step S530: Obtain the pressure value inside the housing 2. When the pressure value reaches the preset value, start timing.

[0087] In this embodiment, a pressure gauge 403 is installed on the cover 3 to detect the pressure value inside the housing 2.

[0088] Step S540: Compare the timed duration with the preset duration. When the timed duration reaches the preset duration, stop pumping air.

[0089] In this embodiment, the pumping is stopped after a preset time. This time can be determined based on the required pressure value inside the housing 2.

[0090] Step S550: Close the working valve 404 and open the vent valve 402 until the pressure value is equal to zero.

[0091] It should be noted that closing the working valve 404 stops the defoaming operation. Opening the vent valve 402 releases the pressure inside the housing 2, facilitating operations such as opening the cover 3.

[0092] In this embodiment, the vent valve 402 controls the connection between the interior of the housing 2 and the outside, and the working valve 404 controls the connection between the vacuum pump and the interior of the housing 2. After the vacuum pump is connected to the interior of the housing 2, it performs a vacuuming operation to expel air bubbles. To prevent the slurry inside the housing 2 from being drawn out during the venting process, the venting continues for a preset time after the pressure inside the housing 2 reaches a preset value and then stops. After the venting stops, the pressure inside the housing 2 decreases, and under the negative pressure, it will create an adsorption effect on the cover 3. Therefore, the vent valve 402 needs to be opened to release the pressure, making it easier to open the cover 3 subsequently.

[0093] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
