[0014] An automatic conveying method for quartz grinding powder suspension with self-cleaning function, implemented using the aforementioned automatic conveying device for quartz grinding powder suspension with self-cleaning function, includes the following steps: S1: Add the weighed quartz powder to the inside of the mixing tank; S2: The water distribution mechanism works, adding clean water to the inside of the mixing tank in a certain proportion.

[0015] The present invention has the following beneficial effects: This invention achieves the preparation of quartz grinding powder suspension by setting up a water distribution mechanism, a power mechanism, and a stirring mechanism. The water distribution mechanism precisely controls the delivery of clean water through a metering pump, ensuring that the quartz grinding powder and clean water are mixed in a preset ratio to meet the process requirements for suspension concentration. The power mechanism provides stable power to the stirring mechanism, which thoroughly mixes the quartz grinding powder and clean water to form a uniform and stable suspension. This replaces the traditional manual batching and stirring methods in the preparation of quartz grinding powder suspension, not only reducing labor intensity but also significantly improving the efficiency of suspension preparation.
[0016] This invention achieves backwashing and forward rinsing by setting up a first solenoid valve, a second solenoid valve, an electric three-way reversing valve, a self-priming pump, and an electric multi-way reversing valve.

Detailed Implementation
[0020] Reference Figure 1-6This invention provides an automatic conveying device for quartz grinding powder suspension with self-cleaning function, comprising a housing 1, a fixing plate 2 fixedly connected to the upper end of the housing 1, a stirring tank 3 and a water storage tank 4 fixedly connected inside the fixing plate 2, three stirring tanks 3 arranged in a circumferential array, each stirring tank 3 having a stirring mechanism 6 inside; a power mechanism 5 is provided at the upper end of the fixing plate 2, which provides power to the stirring mechanism 6; a water distribution mechanism is provided at the lower end of the water storage tank 4, which delivers a fixed amount of clean water into the stirring tanks 3; an electric multi-way reversing valve 20 is fixedly connected to the bottom end of the housing 1. The circumferential interface is fixedly connected to a material conveying pipe 21 and a water conveying pipe 22. The material conveying pipe 21 has three parts, each corresponding to a mixing tank 3 and connected to the mixing tank 3. The water conveying pipe 22 is connected to a water storage tank 4. The lower end interface of the electric multi-way reversing valve 20 is fixedly connected to a first liquid inlet pipe 11. The lower end of the housing 1 is fixedly connected to a self-priming pump 12 and an electric three-way reversing valve 14. The liquid inlet of the self-priming pump 12 is fixedly connected to the first liquid inlet pipe 11. The liquid outlet of the self-priming pump 12 is fixedly connected to the interface at the front end of the electric three-way reversing valve 14 through the first liquid outlet pipe 13. The interface on the left side of the electric three-way reversing valve 14 is fixedly connected to an output pipe 15.
[0021] When in use, weigh out the quartz grinding powder of different mesh sizes and add it into the mixing tank 3. Then, the water dispensing mechanism will add the clean water in the water storage tank 4 into the mixing tank 3 according to the set ratio. At the same time, the power mechanism 5 will work. The power is transmitted to the stirring mechanism 6, which mixes the quartz grinding powder with water to form a quartz grinding powder suspension. After the suspension is prepared, the stirring mechanism 6 needs to be continuously rotated to prevent the quartz grinding powder from settling. Then, the electric multi-way reversing valve 20 connects to the stirring tank 3 containing suspensions of different mesh sizes through the feed pipe 21 as needed, and the electric three-way reversing valve 14 is switched to the left end to connect with the left end interface. Then, the self-priming pump 12 works in the forward direction, allowing the suspension inside the stirring tank 3 to enter the first inlet pipe 11 through the feed pipe 21 and the electric multi-way reversing valve 20, and then enter the first outlet pipe 13 under the action of the self-priming pump 12. Then, it enters the outlet pipe 15 along the electric three-way reversing valve 14, and finally is transported to the surface of the hard material through the outlet pipe 15, thus facilitating subsequent polishing or grinding operations.
[0022] The water distribution mechanism includes a second inlet pipe 23, a metering pump 24, a second outlet pipe 25, a distribution frame 26, and a distribution pipe 27. The metering pump 24 is fixedly connected to the lower end of the water storage tank 4. The inlet end of the metering pump 24 is fixedly connected to the second inlet pipe 23, which is connected to the water storage tank 4. The outlet end of the metering pump 24 is fixedly connected to the second outlet pipe 25. The end of the second outlet pipe 25 away from the metering pump 24 is fixedly connected to the distribution frame 26. The upper end of the distribution frame 26 is fixedly connected to the distribution pipe 27. There are three distribution pipes 27, which correspond one-to-one with the mixing tank 3. The three distribution pipes 27 are connected to the mixing tank 3 respectively. During operation, the metering pump 24 draws clean water from the water storage tank 4 through the second inlet pipe 23, delivers it to the distribution frame 26 through the second outlet pipe 25, and then the distribution frame 26 evenly distributes the clean water to the three distribution pipes 27, and finally injects it into the corresponding mixing tank 3. The metering pump 24 controls the amount of clean water delivered per unit time according to the preset mixing parameters, ensuring that the quartz grinding powder and clean water in each mixing tank 3 can be mixed in the set ratio, providing a reliable guarantee for the preparation of a suspension with stable concentration.
[0023] The power mechanism 5 includes a drive gear 501, a transmission gear 502, and a motor 503. The motor 503 is fixedly connected to the lower end of the fixed plate 2. The output end of the motor 503 passes through the fixed plate 2 and is rotatably connected to the fixed plate 2. The output end of the motor 503 is fixedly connected to the drive gear 501. The drive gear 501 is meshed with the transmission gear 502 on its side. There are three transmission gears 502, which correspond one-to-one with the stirring tank 3. When working, after the motor 503 starts, it drives the drive gear 501 at the output end to rotate. Since the drive gear 501 meshes with the three transmission gears 502, the rotation of the drive gear 501 will synchronously drive the three transmission gears 502 to rotate synchronously, thus providing the power source for the stirring mechanism 6. This ensures that the stirring mechanisms 6 in the three stirring tanks 3 can work simultaneously, improving the efficiency of suspension preparation.
[0024] The stirring mechanism 6 includes a fixed frame 601, a rotating shaft 602, and stirring blades 603. The fixed frame 601 is fixedly connected inside the stirring tank 3, and the rotating shaft 602 is rotatably connected inside the fixed frame 601. The upper end of the rotating shaft 602 is fixedly connected to the transmission gear 502, and the stirring blades 603 are fixedly connected to the circumferential surface of the lower end of the rotating shaft 602. During operation, as the transmission gear 502 rotates, it can drive the rotating shaft 602 to rotate inside the fixed frame 601, which in turn drives the stirring blades 603 to rotate. The rotating stirring blades 603 can fully agitate the quartz grinding powder and water in the stirring tank 3, so that the quartz grinding powder is evenly dispersed in the water to form a stable suspension.
[0025] An inlet pipe 18 is fixedly connected to the interface on the right side of the electric three-way reversing valve 14. The inlet pipe 18 passes through the lower end of the housing 1 and is connected to the water storage tank 4. A second solenoid valve 19 is fixedly installed on the inlet pipe 18. A first solenoid valve 16 is fixedly installed on the output pipe 15. During operation, when reverse flushing is required, the first solenoid valve 16 closes, the second solenoid valve 19 opens, and the electric three-way reversing valve 14 is switched to the right end, connecting to the right end interface. This allows the self-priming pump 12 to work in reverse, causing the clean water inside the water storage tank 4 to enter the electric three-way reversing valve 14. 4. The first liquid outlet pipe 13, the first liquid inlet pipe 11, the self-priming pump 12, the electric multi-way reversing valve 20, and the conveying pipe 21 are all connected to the inside of the mixing tank 3, and then the liquid flows back to the inside of the mixing tank 3, thus achieving the purpose of reverse cleaning. When forward cleaning is required, the first solenoid valve 16 is opened, the second solenoid valve 19 is closed, and the electric multi-way reversing valve 20 is connected to the water storage tank 4 through the water conveying pipe 22. At the same time, the electric three-way reversing valve 14 is switched to the left end, so that it is connected to the left end interface. Then the self-priming pump 12 works in the forward direction, so that the clean water is discharged from the output pipe 15, thus achieving the purpose of forward cleaning.
[0026] A first turbidity sensor 17 is fixedly installed on the output pipe 15; a second turbidity sensor 28 is fixedly installed on each of the three feed pipes 21. During operation, the first turbidity sensor 17 is used to detect whether the liquid inside the output pipe 15 is clear during forward cleaning, and the second turbidity sensor 28 is used to detect whether the liquid inside the feed pipe 21 is clear during reverse rinsing. At the same time, the second turbidity sensor 28 can also detect whether the concentration of the suspension inside the mixing tank 3 meets the requirements during feeding. If it does not meet the requirements, quartz grinding powder needs to be added.
[0027] A connecting arm 9 is fixedly connected to the right side of the housing 1, and a controller 7 is fixedly connected to the lower end of the connecting arm 9. During operation, the metering pump 24, the self-priming pump 12, the electric three-way reversing valve 14, the electric multi-way reversing valve 20, the first solenoid valve 16, and the second solenoid valve 19 can be conveniently controlled by the controller 7.
[0028] A water inlet 10 is provided on the upper surface of the water storage tank 4. The water inlet 10 is located near the edge of the tank body 1. During operation, the water inlet 10 facilitates the addition of clean water into the water storage tank 4.
[0029] The lower end of the housing 1 is fixedly connected to a support leg 8. There are four support legs 8, which are evenly distributed at the four corners of the lower end of the housing 1. During operation, by setting the support legs 8, the lower end of the housing 1 is kept away from the ground, which facilitates the installation of the equipment at the lower end of the housing 1.
[0030] An automatic conveying method for quartz grinding powder suspension with self-cleaning function, implemented using the aforementioned automatic conveying device for quartz grinding powder suspension with self-cleaning function, includes the following steps: S1: Add the weighed quartz powder to the inside of mixing tank 3; S2: The water distribution mechanism works, adding clean water to the inside of the mixing tank 3 in a certain proportion. At the same time, the power mechanism 5 works, transmitting power to the mixing mechanism 6. Under the action of the mixing mechanism 6, the quartz grinding powder and clean water are mixed together to form a quartz grinding powder suspension. S3: The electric multi-way reversing valve 20 can be connected to the stirring tank 3 containing suspensions of different mesh sizes as needed; S4: The electric three-way reversing valve 14 is switched to the left end, so that it is connected to the left end interface; S5: Then the self-priming pump 12 works to make the suspension enter the first outlet pipe 13 through the first inlet pipe 11, and then enter the output pipe 15 through the electric three-way reversing valve 14, and finally output from the output pipe 15 to the surface of the hard material. S6: During reverse cleaning, the first solenoid valve 16 is closed, the second solenoid valve 19 is opened, and the electric three-way reversing valve 14 is switched to the right end to connect with the right end interface. Then the self-priming pump 12 works in reverse, so that the clean water inside the water storage tank 4 enters the electric three-way reversing valve 14, the first outlet pipe 13, the first inlet pipe 11, the self-priming pump 12, the electric multi-way reversing valve 20 and the conveying pipe 21, and then flows back into the mixing tank 3, thus achieving the purpose of reverse cleaning. S7: During forward cleaning, the first solenoid valve 16 is opened, the second solenoid valve 19 is closed, and the electric multi-way reversing valve 20 is connected to the water storage tank 4. At the same time, the electric three-way reversing valve 14 is switched to the left end, so that it is connected to the left end interface. Then the self-priming pump 12 works in the forward direction, so that clean water is discharged from the output pipe 15, thus achieving the purpose of forward cleaning.
[0031] Working principle: In use, quartz grinding powder of different mesh sizes is weighed separately and then added to the three mixing tanks 3. Next, the controller 7 activates the water distribution mechanism, and the metering pump 24 draws clean water from the storage tank 4 through the second inlet pipe 23, delivers it to the distribution frame 26 through the second outlet pipe 25, and then the distribution frame 26 evenly distributes the clean water to the three distribution pipes 27, finally injecting it into the corresponding mixing tank 3. Simultaneously, the controller 7 activates the power mechanism 5, and the motor 503 drives the drive gear 501 at the output end to rotate. The drive gear 501 then meshes with and drives the three transmission gears 502 to rotate synchronously. The rotation of the transmission gears 502 causes the rotating shaft 602 in the stirring mechanism 6 to rotate within the fixed frame 601. The stirring blades 603 at the lower end of the rotating shaft 602 rotate accordingly, thoroughly agitating the quartz grinding powder and clean water in the mixing tank 3, mixing them to form a quartz grinding powder suspension.
[0032] When a suspension of a specific mesh size needs to be delivered, the controller 7 controls the electric multi-way directional valve 20 to switch, connecting it to the mixing tank 3 containing the required mesh size suspension via the corresponding feed pipe 21. Simultaneously, the electric three-way directional valve 14 switches to the left, connecting it to the output pipe 15 on the left. Subsequently, the self-priming pump 12 operates in the forward direction, pumping the suspension in the mixing tank 3 sequentially through the feed pipe 21, the electric multi-way directional valve 20, the first inlet pipe 11, the self-priming pump 12, the first outlet pipe 13, and the electric three-way directional valve 14 into the output pipe 15. Finally, the suspension is delivered from the output pipe 15 to the surface of a hard material for subsequent polishing or grinding operations.
[0033] When it is necessary to switch to suspensions of different mesh sizes or when the equipment is not used for a long period of time, a cleaning operation can be performed. During reverse cleaning, the controller 7 controls the first solenoid valve 16 to close and the second solenoid valve 19 to open. The electric three-way reversing valve 14 is switched to the right end, connecting it to the inlet pipe 18 interface on the right end. Then, the self-priming pump 12 works in reverse, and the clean water in the water storage tank 4 flows back to the mixing tank 3 through the inlet pipe 18, the electric three-way reversing valve 14, the first outlet pipe 13, the self-priming pump 12, the first inlet pipe 11, the electric multi-way reversing valve 20, and the conveying pipe 21, performing reverse flushing on these pipes and pump chambers. At this time, the second turbidity sensor 28 will detect whether the liquid in the conveying pipe 21 is clear to determine whether the cleaning is thorough. During forward cleaning, the first solenoid valve 16 is opened, the second solenoid valve 19 is closed, the electric multi-way reversing valve 20 is switched to connect with the water supply pipe 22 of the water storage tank 4, the electric three-way reversing valve 14 remains connected to the output pipe 15, the self-priming pump 12 operates in the forward direction, and clean water is discharged from the output pipe 15 through the water supply pipe 22, the electric multi-way reversing valve 20, the first inlet pipe 11, the self-priming pump 12, the first outlet pipe 13, and the electric three-way reversing valve 14 in sequence, thus achieving forward cleaning. The first turbidity sensor 17 is used to detect the clarity of the liquid in the output pipe 15.
