[0039] A solid-liquid mixing device for a fine particulate material mixture solution includes: a material tank 2, a solution tank 12, a stirring tank 7, and discharge rollers 16. The material tank 2 is used to store powdered solid materials, and a material outlet 4 is provided at the bottom of its side wall. The solution tank is used to store liquid materials, and a solution outlet 10 is provided at the bottom of its side wall. The stirring tank 7 is located between the material tank 2 and the solution tank 12. The material outlet 4 is connected to a spray pipe 6 inside the stirring tank 7, and the solution outlet 10 is connected to a spray pipe 8 inside the stirring tank 7. The spray pipe 6 and the spray pipe 8 are arranged at the same height and with opposite spray directions. A stirring paddle 14 is provided inside the stirring tank 7, and a spray nozzle is provided at the outlet of the spray pipe 8. The discharge rollers 16 are located at the discharge port at the bottom of the stirring tank 7, and the discharge speed of the stirring tank 7 can be adjusted by adjusting the rotation speed of the discharge rollers 16. Fine particulate materials refer to powders.

[0040] This device mainly consists of a mixing tank 7 with a certain volume, a material tank 2, and a solution tank 12. The mixing tank 7 is equipped with a stirring paddle 14, which is driven by a first motor 13 installed outside the tank. The mixing tank 7 has a discharge port at the bottom, and a discharge roller 16 is provided at the discharge port 15. The discharge roller 16 is driven by a second motor 17. The discharge roller 16 is actually a roller mill, and the specific structure is existing technology. Depending on the requirements of the output material, rollers with concave surfaces can be selected, such as the structure on a roller granulator, so that the discharged material can be in granular form. Both the material tank 2 and the solution tank 12 have inclined bottoms, with discharge holes at the bottom. The material discharge port 4 is connected to a pneumatic powder diaphragm pump 5 via a discharge pipe. The other end of the pneumatic powder diaphragm pump 5 is connected to a spray pipe 6, which leads to the interior of the mixing tank 7 through an opening.

The other end of the pressure pump 9 is connected to a spray pipe 8, which leads to the interior of the mixing tank 7 through an opening. The spray pipe 8 is equipped with a spray nozzle.

[0041] When this device is in use, the spray pipe 8 and the spray pipe 6 spray each other, and the two materials will initially come into contact and mix. At this time, the discharge speed of the discharge roller 16 is slow, so that the initially mixed material can accumulate above the discharge roller 16 and be fully stirred by the stirring paddle 14. Then, the speed of the discharge roller 16 can be increased, so that the fully mixed material is discharged.

[0042] In one specific embodiment, the top of the mixing tank 7 is sealed, and two holes are opened on the side wall of the mixing tank 7, which are respectively connected to the material tank 2 and the solution tank 12, so that the dust inside the mixing tank 7 will not overflow.

[0043] Both solution tank 12 and material tank 2 are sealed structures.

[0044] In one specific embodiment, the device further includes: a pneumatic powder diaphragm pump 5 and a pressure pump 9.

[0045] The pneumatic powder diaphragm pump 5 is installed at the material outlet 4, and the pneumatic powder diaphragm pump 5 is used to drive the powdered solid material to be sprayed out from the spray pipe 6. The pressure pump 9 is installed at the solution outlet 10, and the pressure pump 9 is used to drive the liquid material to be sprayed out from the spray pipe 8.

[0048] The device also includes a frame 1, which includes a vertical plate, a base 19, and a fixing plate; two vertical plates are arranged in parallel and vertically mounted on the base 19, and two fixing plates are respectively arranged on the inner wall of each vertical plate from top to bottom; the material tank 2 is mounted on the top fixing plate of one vertical plate, and the solution tank 12 is mounted on the top fixing plate of the other vertical plate; the outer wall of the mixing tank 7 is connected by four fixing plates, and the discharge rollers 16 are installed below the stirring paddle 14.

[0052] Before starting the machine, check that all parts of the device are in good working order. After the check is completed, pour the materials and solutions to be mixed into the material tank 2 and solution tank 12 from the loading port at the top of the tank. Then turn on the switch of the stirring paddle 14 inside the mixing tank 7, and then turn on the switches of the pneumatic powder diaphragm pump 5 and the pressurizing pump 9 to start spraying the materials and solutions into the mixing tank 7 and start the mixing operation. Then, according to the mixing of the materials discharged from the outlet, adjust the outlet device to control the discharge speed. The uniformly mixed materials are discharged from the outlet into the storage tank 18. During the operation of the device, add materials and solutions according to the discharge situation until all materials are mixed.

[0053] This device employs a preliminary mixing process of fine-particle materials and solution via spraying, followed by further mixing via a stirring paddle 14, achieving thorough mixing of the solid and liquid phases. The discharge port 15 of the mixing tank is equipped with discharge rollers 16, which control the discharge speed and prevent clogging. The device uses a pneumatic powder diaphragm pump 5 and a pressure pump 9 to spray materials for mixing, with the discharge port 15 controlling the discharge speed, enabling continuous material mixing.
