Detailed Implementation

[0031] The following is combined with Figure 1-4 This utility model will be described in detail.

[0032] An automatic quantitative feeding mixing device includes a support frame 10, the support frame 10 being equipped with a material hopper 30, comprising:

[0033] A feeding device is provided on the support 10. The feeding device includes a feeding tray 201, which can reciprocate between a first position and a second position. The feeding tray 201 is sealed and movably adapted to the discharge end of the material barrel 30. The feeding tray 201 is provided with a metering hole 2011.

[0034] The mixing device includes a turntable 501 and a mixing tank 502 that is driven to the turntable 501. When the feeding plate 201 is in the first position, the metering hole 2011 is connected to the discharge end of the material tank 30. When the feeding plate 201 is in the second position, the metering hole 2011 is connected to the mixing tank 502.

[0035] A monitoring device is installed inside the mixing tank 502 to monitor the concentration of the slurry inside the mixing tank 502;

[0036] The slurry conveying device has its slurry outlet connected to the slurry mixing tank 502; and

[0037] A control device is electrically connected to the feeding device, the slurry conveying device, and the monitoring device. The control device analyzes the data obtained by the monitoring device and the required material and / or slurry for the mixing tank 502, and then drives the feeding device and / or the slurry conveying device to deliver a certain amount of material and / or slurry to the mixing tank 502.

[0038] The discharge end of the aforementioned material hopper 30 is equipped with a sealing flange, which fits against the feeding disc 201. This ensures that when the metering hole 2011 is vertically aligned with the discharge end of the material hopper 30, the powder in the material hopper 30 falls into the metering hole 2011 and does not spill to the outside. When the metering hole 2011 is vertically aligned with the vibrating disc 401, the powder in the material hopper 30 is blocked by the powder feeding disc.

[0039] In this embodiment, the support 10 is further provided with a vibration device, which includes a vibrating disc 401. The discharge end of the vibrating disc 401 is connected to the feed end of the mixing tank 502, and when the feeding disc 201 is in the second position, the metering orifice 2011 is connected to the vibrating disc 401. Further, the vibration device also includes a vibration motor 402, which is drivenly connected to the vibrating disc 401; the slurry outlet is located above the inner edge of the opening of the mixing tank 502.

[0040] The vibration device operates at different frequencies based on the particle size of the powder, ensuring that powders of varying sizes are evenly distributed in the mixing tank 502. The control unit is user-friendly; simply input the concentration ratio of the silica slurry, and the system will generate the powder-to-slurry ratio and automatically mix and blend. Therefore, only one person is needed to operate the machine on a fixed production line, significantly reducing manpower and ensuring more standardized and uniform slurry mixing, thus lowering overall costs.

[0041] Furthermore, the feeding device also includes a chassis 202, on which a slide rail 2021 is provided. The feeding disc 201 is slidably connected to the slide rail 2021. When the feeding disc 201 moves to the first position, the lower end of the metering orifice 2011 is blocked by the chassis 202, and the powder in the vibrating disc 401 spills onto the inner edge of the opening of the mixing tank 502. Furthermore, the feeding device also includes a drive cylinder 203, which is drivenly connected to the feeding disc 201, causing the feeding disc 201 to reciprocate between the first and second positions via the slide rail 2021.

[0042] When the metering orifice 2011 is vertically aligned with the discharge end of the material container 30, the powder in the material container 30 can fall into the metering orifice 2011 through the discharge end. When the metering orifice 2011 is vertically aligned with the vibrating plate 401, the powder falling into the metering orifice 2011 can fall onto the vibrating plate 401. Conversely, when the metering orifice 2011 is aligned with the discharge end of the material container 30, the discharge end of the material container 30 is blocked by the feeding plate 201. The powder has a certain particle size and good flowability. The powder falling into the metering orifice 2011 can move with the metering orifice 2011 to the top of the vibrating device.

[0043] In this embodiment, a support rod 60 is provided on one side of the turntable 501. The support rod 60 extends into the opening of the mixing tank 502 with a support portion 601. The support portion 601 is provided with a baffle device that extends into the mixing tank 502. Further, the baffle device includes a first fixing frame 701, which is fixed to the support portion 601. The first fixing frame 701 is provided with a plurality of first stirring baffles 703 arranged axially along the mixing tank 502. The first stirring baffles 703 are set at an angle to the inner sidewall of the mixing tank 502. Further, a second fixing frame 702 is provided at the end of the first stirring baffles 703 away from the first fixing frame 701. The second fixing frame 702 is provided with a second stirring baffle 704 arranged radially along the mixing tank 502. The second stirring baffle 704 is composed of at least two baffle bodies. The two baffle bodies are arranged coaxially and have an included angle between them. The two baffle bodies are set at an angle to the bottom surface of the mixing tank 502.

[0044] Both the first fixing frame 701 and the second fixing frame 702 are circular fixing rings. Preferably, the two ends of the first stirring baffle 703 are vertically connected to the first fixing frame 701 and the second fixing frame 702 respectively, and are distributed around the central axis of the first fixing frame 701 and the second fixing frame 702. Preferably, there are four of them. The first stirring baffle 703 forms an angle of 0° to 90° with the inner side wall of the mixing tank 502, preferably a right angle. Preferably, there are two baffle bodies. The baffle bodies form an angle of 0° to 90° with the bottom surface of the mixing tank 502, preferably an acute angle.

[0045] The first mixing baffle 703 consists of four sets of stainless steel plates, each set of baffles being bolted to the first fixed frame 701 extending from the support rod 60. The plane of the baffle forms a 90° angle with the inner wall of the mixing tank 502, and the installation direction is opposite to the rotation direction of the turntable 501. When the mixing tank 502 rotates, the baffles prevent the slurry from rotating synchronously with the tank, generating shear force, and simultaneously squeezing the slurry towards the center of the mixing tank 502, breaking the laminar flow state and promoting radial mixing.

[0046] The second mixing baffle 704 is located at the end of the first mixing baffle 703 and is connected by the second fixing frame 702. Each set consists of two V-shaped baffle bodies with an included angle of 60°; the baffles are inclined at 15° to the bottom surface of the mixing tank 502, extending to 10mm from the bottom of the tank. The lower layer of slurry is folded upward under the guidance of the V-shaped baffles, forming convection with the upper layer of slurry; the inclined angle design avoids the sedimentation of the bottom slurry and enhances the axial mixing efficiency.

[0047] The turntable 501 is driven by a servo motor, and the inner wall of the mixing tank 502 is provided with spiral-shaped guide protrusions. The first stirring baffle 703 has an angle of 30° with the inner wall of the mixing tank 502, and the two baffle bodies of the second stirring baffle 704 have an angle of 60° and are inclined at 15° to the bottom surface. When the turntable 501 rotates, the torque is transmitted to the mixing tank 502 through the drive shaft, causing it to rotate synchronously. The support rod 60 located on one side of the turntable 501 remains fixed. The first baffle pushes the slurry towards the center, and the second baffle folds the slurry at the bottom upwards, forming a three-dimensional turbulence and accelerating mixing.

[0048] In this embodiment, the monitoring device includes a torque detector and a liquid level detector. The torque detector and the liquid level detector are electrically connected to the control device. The control device drives the feeding device and / or the slurry conveying device to deliver the material and / or slurry to the mixing tank 502 based on the torque value obtained by the torque detector and the liquid level obtained by the liquid level detector.

[0049] The torque detector includes a non-contact magnetoelastic torque sensor integrated into the 501 drive shaft of the turntable; a current detection module that collects the operating current of the servo motor through a Hall effect sensor and calculates the real-time torque value by combining the motor power-torque curve; and a signal processing unit that converts the raw signal into a standard signal output.

[0050] The liquid level detector includes a laser rangefinder sensor: employing the Time-of-Flight (TOF) principle, located above the mixing tank 502. The laser sensor emits pulsed light, and by measuring the time difference between the light's emission and its reflection from the liquid surface, the liquid level height is calculated. The processed data is then transmitted to the control device in real time.

[0051] When the mixing tank 502 rotates, the viscosity of the slurry is positively correlated with the resistance, and the load torque of the drive motor changes accordingly. When the slurry concentration increases, the viscosity increases, the drive shaft torque increases, and the motor current increases synchronously. The torque sensor and current detection data are fused and processed, and the slurry concentration is inferred in real time through a pre-calibrated viscosity-torque mapping model.

[0052] In this embodiment, the slurry delivery device is a slurry delivery pipe equipped with an electrically controlled valve, which is electrically connected to a control device. The input end of the slurry delivery pipe is connected to a solvent tank, and its output end is connected to the opening of the mixing tank 502.

[0053] The present invention provides an automatic quantitative feeding mixing device, the usage method of which is as follows:

[0054] By operating the control device's back-end terminal and inputting the slurry concentration ratio, the system can generate the powder-to-glue ratio and automatically mix and blend the mixture.

[0055] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
