[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please also refer to Figure 1 , Figure 2 and Figure 3The sanding medium supply system 100 includes a sanding medium supply device 10 and a sanding mill 30. The sanding mill 30 is provided with a filtering structure (not shown in the figure), which is an important component of the sanding mill 30 and is used to filter the sanding medium (not shown in the figure) and the slurry during the slurry processing.

[0024] The sand grinding medium supply device 10 includes a medium tank 1, a circulation tank 3 and a pump 5. The bottom of the medium tank 1 is provided with a first discharge port 111, and the medium tank 1 is used to store the sand grinding medium; the bottom of the circulation tank 3 is provided with a second discharge port 311 and a reflux port 331, and the circulation tank 3 is used to store and flow water; the input end 501 of the pump 5 is connected to the second discharge port 311, and the output end 503 of the pump 5 is connected to the first discharge port 111 through a three-way pipe 7, and the outlet of the three-way pipe 7 and the reflux port 331 are respectively used to be connected to the sand mill 30, and the sand grinding medium and water are separated in the filtering structure.

[0025] The sanding medium supply system 100 cooperates with the filtering structure through the sanding medium supply device 10, and realizes the addition of the sanding medium without adding other structures. The sanding medium supply device 10 is separately arranged with the sand mill 30, and is connected when addition is needed, which is relatively simple to use and will not affect the normal operation of the sand mill 30.

[0026] The sand mill medium supply device 10 is connected and matched with the sand mill 30 by setting the medium tank 1, the circulation tank 3 and the pump 5. Under the action of the pump 5, water flows out of the circulation tank 3, passes through the second discharge port 311, the pump 5 and the three-way pipe 7, mixes with the sand mill medium flowing out of the medium tank 1, and flows into the sand mill 30 together. After separation by the filtering structure, the water overflows from the sand mill 30 and re-enters the circulation tank 3 through the reflux port 331. During the whole process, the water flows continuously and brings the sand mill medium into the sand mill 30 to achieve the addition of the sand mill medium. The whole process can be completed without the continuous participation of personnel, which greatly saves manpower and improves the efficiency of adding the sand mill medium. Moreover, the water and the sand mill medium are stored through the circulation tank 3 and the medium tank 1, and the adding environment is safe and controllable, and no other pollutants will enter the grinding cylinder of the sand mill 30.

[0027] The medium tank 1 includes a first tank body 11, a first upper cover 13 and a first support leg 15. The first discharge port 111 is provided in the first tank body 11, and the bottom of the first tank body 11 is inclined and contracted from the side wall toward the first discharge port 111. The overall structure of the first tank body 11 is a combination of a cylinder and an inverted cone, and the first discharge port 111 is provided at the bottom of the cone. Based on the action of gravity, the sanding medium flows out from the first discharge port 111 into the three-way pipe 7 to mix with water. The setting of the first discharge port 111 and the first tank body 11 ensures that the sanding medium can flow out completely without the need for additional power, which is convenient and efficient.

[0028] The first upper cover 13 is tightly fitted with the first tank body 11, and the first upper cover 13 is provided with a barometer 17 for detecting the internal pressure of the first tank body 11. The first upper cover 13 is provided with a first feed port 131 and an exhaust port 133. The first feed port 131 is used to put the sanding medium into the first tank body 11; the exhaust port 133 is used to release the pressure of the first tank body 11. The first feed port 131 and the exhaust port 133 are arranged at intervals on the first upper cover 13, and the first feed port 131 and the exhaust port 133 are both provided with a connector 1301, and a valve is provided on the connector 130.

[0029] The first upper cover 13 and the first tank body 11 can be connected and tightened by setting a flange structure, so that a closed environment is formed inside the first tank body 11, ensuring that the storage environment of the sanding medium is safe and hygienic. Of course, the upper cover 13 and the first tank body 11 can also be connected by other connection methods, which will not be elaborated here. The barometer 17 can monitor the air pressure inside the first tank body 11. When the air pressure is too high, the exhaust port 133 can be controlled to exhaust air, thereby improving the safety and reliability of equipment operation. Valves are provided on the connector 130 provided at the first feed port 131 and the exhaust port 133, which are used to control the connection relationship between the first tank body 11 and the outside world, ensuring the sealing effect of the first tank body 11 while facilitating control.

[0030] In another embodiment, a controller (not shown) may be provided on the valve on the exhaust port 133. By providing a sensor to detect the air pressure signal in the first tank body 11, the controller identifies the air pressure signal and controls the switch state of the valve accordingly to achieve automatic pressure relief.

[0031] The first legs 15 are circumferentially spaced apart on the sidewalls of the first tank body 11. The first legs 15 can not only be used to support the first tank body 11, but also increase the height of the first tank body 11, making it easier to install and use the first discharge port, and increase the height potential energy of the sanding medium, making it easier for the sanding medium to flow out.

[0032] The first upper cover 13 is also provided with a cleaning port 135 for cleaning the interior of the first tank body 11. The cleaning port 135 is spaced apart from the first feed port 131 and the exhaust port 133, and a sealing cover 1303 is provided on the cleaning port 135. Through the cleaning port 135, the operator can clean the interior of the first tank body 11 with a high-pressure water gun or a cleaning device, avoiding frequent disassembly of the first tank body 11 and the first upper cover 13 to damage the sealing structure. The sealing cover 1303 is also used to ensure that the closed space formed by the first tank body 11 and the first upper cover 13 is safe and hygienic. When cleaning is not required or when the sanding medium is added, the sealing cover 1303 is tightly fitted with the cleaning port 135 and opened when cleaning is required. The operation is relatively simple, and if there is a problem with the sealing effect of the sealing cover 1303, only the sealing cover 1303 needs to be maintained and replaced, thereby increasing the service life of the sealing structure between the first tank body 11 and the first upper cover 13 and reducing maintenance costs.

[0033] The circulation tank 3 includes a second tank body 31, a second upper cover 33 and a second support leg 35. The reflux port 331 is provided on the second tank body 31. The bottom of the second tank body 31 is inclined and contracted from the side wall to the second discharge port 311. The second upper cover 33 is connected to the second tank body 11. The second support leg 35 is circumferentially spaced on the side wall of the second tank body 11. The second tank body 31 is basically the same as the first tank body 11, and the second support leg 35 is the same as the first support leg 15, and the technical effect is the same. Due to the same setting, it can be used in one body for two purposes, and no additional mold opening and processing are required during manufacturing, which reduces processing costs and makes maintenance more convenient.

[0034] A drain port 101 is provided at the bottom of the first tank body 11 and the second tank body 31, and a valve is provided on the drain port 101. The drain port 101 can be used not only for cleaning the first tank body 11 and the second tank body 31, but also for draining the water in the first tank body 11 and the second tank body 31 after the sanding medium is added. In particular, after the sanding medium is added, in order not to affect the use of the sand mill 30, the sanding medium supply device 10 as a whole needs to be separated from the sand mill 30. Through the drain port 101, the water used to add the sanding medium can be drained, thereby reducing the weight of the sanding medium supply device 10 as a whole and facilitating transfer.

[0035] The first tank body 11, the first upper cover 13 and the second tank body 31 are all provided with a spare port 103. The function of the spare port 103 is not directly limited, and it can be used as a backup when an existing functional port has a problem, or it can be convenient for adding new functions later.

[0036] The pump 5 is a pneumatic diaphragm pump, including a pump body 51, a muffler 53, a first pump chamber 55 and a second pump chamber 57. The muffler 53 is arranged on the pump body 51; the first pump chamber 55 is arranged on one side of the pump body 51; the second pump chamber 57 is arranged on the other side of the pump body 51 relative to the first pump chamber 55; the upper end of the first pump chamber 55 is connected to the upper end of the second pump chamber 57, and is provided with the input end 501, and the input end 501 is connected to the second discharge port 311; the lower end of the first pump chamber 55 is connected to the lower end of the second pump chamber 57, and is provided with the output end 503, and the output end 503 is connected to the first discharge port 111. The pneumatic diaphragm pump uses compressed air as a power source and has low noise. The pneumatic diaphragm pump is not only small in size and easy to place and move, but also used in conjunction with the medium tank 1 and the circulation tank 3, so that the overall structure design of the sand mill medium supply device 10 is ingenious; it can also be used to pass particles, and is very suitable for use with the sand mill 30. Since there may be residual slurry from grinding in the sand mill 30, the water in the circulation tank 3 that flows back from the sand mill 30 may be mixed with certain particles, and the pneumatic diaphragm pump can smoothly pass through without being easily blocked. Moreover, the pneumatic diaphragm pump has an adjustable flow rate, which is convenient for controlling the speed of increasing the sand milling medium. If the sand milling medium accidentally flows back and causes pipeline obstruction, the pneumatic diaphragm pump also has the function of automatically stopping, which is safer.

[0037] The sanding medium supply device 10 also includes a moving mechanism 9, which includes a frame 91, wheels 93 and a push handle 95. The medium tank 1, the circulation tank 3 and the pump 5 are all arranged on the frame 91; wheels 93 are arranged below the frame 91; a push handle 95 is arranged on one side of the frame 91, and is used to move the frame 91 in cooperation with the wheels 93. The moving mechanism 9 is mainly used to carry and transport the medium tank 1, the circulation tank 3 and the pump 5. Since the sand mill 30 is a large-scale equipment and is not conducive to transfer, the sanding medium supply device 10 can be conveniently moved close to or away from the sand mill by setting the moving mechanism 9, so as to facilitate the addition of the sanding medium to the sand mill 30 without affecting the normal use of the sand mill 30. The frame 91, the wheels 93 and the push handle 95 are arranged in coordination, and are easy to push and pull, and are used in conjunction with the drain port 101. After the sanding medium is added, the weight of the medium tank 1 and the circulation tank 3 is first reduced through the drain port 101, and then the transfer is performed, which is very convenient and efficient.

[0038] Please continue to combine Figure 4 The working principle of the sanding medium supply system 100 and the corresponding sanding medium supply method are summarized as follows:

[0039] S01: providing a circulation tank 3 having a second discharge port 311 and a reflux port 331, and injecting water into the circulation tank 3;

[0044] S06: providing the filtering structure to keep the sand milling medium in the sand mill 30 , and allowing water to pass through the filtering structure and overflow from the sand mill 30 , and enter the circulation tank 3 through the reflux port 331 .

[0045] Compared with the prior art, the sand grinding medium supply device 10 provided by the present invention realizes the transmission of the sand grinding medium by setting the medium tank 1, the circulation tank 3 and the pump 5. The circulation tank 3 provides medium water, and the pump 5 provides power. The sand grinding medium is mixed with water and then added to the sand mill 30. This can be completed without the continuous participation of personnel, which greatly saves manpower and improves the efficiency of the sand grinding medium. Moreover, the water and the sand grinding medium are stored through the circulation tank 3 and the medium tank 1, and the adding environment is safe and controllable, and no other pollutants will enter the grinding cylinder.

[0046] In addition, the medium tank 1, the circulation tank 3 and the pump 5 are used in conjunction with the moving mechanism 9, which is highly flexible. The operator can easily control the position of the sanding medium supply device 10, and then install the pipeline connected to the sand mill 30 to achieve the work of adding the sanding medium.

[0047] The sanding medium supply system 100 and the sanding medium supply method provided by the present invention can retain the grinding medium in the grinding cylinder through the filtering structure of the sand mill 30, and return the overflowing water to the circulation tank 3 to form a circulation link, thereby continuously providing sanding medium to the sand mill 30, which is safe, efficient and saves labor costs.

[0048] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
