[0018] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0019] This embodiment provides a laboratory intermittent single-layer wet sieving device, such as... Figure 1-2 As shown, it includes a screen vibration drive device and a water tank horizontal movement drive device.

[0020] The horizontal movement drive device for the water tank includes a water tank 6, a support arm 7, an underflow valve 8, a base 9, a water tank cover plate 13, and a rotary motor (not shown in the figure); the water tank cover plate 13 covers the top of the water tank 6, and the bottom of the water tank 6 is provided with support arms 7 on both sides; the lower end of the support arm 7 is fixed to the base 9, the base 9 is connected to the rotary motor, and the rotary motor can drive the base 9 to rotate horizontally; the bottom of the water tank 6 is provided with an outlet, and the outlet is provided with an underflow valve 8.

[0021] The sieve vibration drive device includes a vibration motor 1, a crossbeam 2, vertical arms 3, a sieve base 5, and a sieve cover plate 12. The sieve base 5 is located in the water tank 6. The vibration motor 1 is driven and connected to the crossbeam 2. Vertical arms 3 are connected to both sides of the crossbeam 2. The lower ends of each vertical arm 3 pass through the water tank cover plate 13 and are connected to both sides of the sieve base 5. The sieve base 5 is ring-shaped and is used to support the sieve. The sieve cover plate 12 is used to cover the top of the sieve.

[0022] In this embodiment, the vibration motor 1 can output high-frequency, low-amplitude up-and-down vibrations, which drive the sieve to vibrate up and down through the crossbeam 2 and the vertical arm 3.

[0023] In this embodiment, the crossbeam 2, vertical arm 3, sieve bottom support 5, and underflow valve 8 are all made of stainless steel. The water tank 6, sieve cover 12, and water tank cover 13 are all made of transparent sheet metal.

[0024] In this embodiment, both the sieve cover plate 12 and the water tank cover plate 13 are provided with sealing plastic rings at their bottom edges. The sealing performance of the sieve and the top of the water tank is enhanced by these sealing plastic rings.

[0025] In this embodiment, the bottom of the water tank 6 is conical, and a water level scale line (not shown in the figure) is provided at a set height on the side wall of the water tank 6.

[0026] In this embodiment, the water tank cover plate 13 has two round holes 10 on each side, and the vertical arms 3 on both sides pass through the round holes 10 on both sides respectively.

[0027] Furthermore, in this embodiment, water-blocking circular plates 11 are respectively provided below the circular holes 10 on both sides. The water-blocking circular plates 11 on both sides are respectively sleeved and fixed on the vertical arm 3 on the corresponding side, and the distance between the water-blocking circular plates 11 and the water tank cover plate 13 is 1mm. The water tank cover plate 13 has circular holes 10 to allow the vertical arm 3 to pass through. The setting of the water-blocking circular plates 11 can prevent water from being thrown out of the circular holes 10 during the screening process.

[0028] The working principle of the above-mentioned intermittent single-layer wet sieving device for laboratory use is as follows:

[0029] After cleaning all components, close the bottom flow valve 8. Then, lift the water tank cover 13 upwards to open the top of the water tank 6 and fill the water tank 6 with water up to the water level mark. Next, place the circular sieve 14 into the water tank 6 and fix it on the sieve base 5 (the circular sieve and sieve base can be fixed using conventional snap-fit ​​or positioning pins, which will not be detailed here). Add the material to be sieved to the circular sieve 14, then cover the top of the circular sieve 14 with the matching sieve cover 12 and tighten it with screws 4. Finally, replace the water tank cover 13 and tighten it with screws 4.

[0030] After the experiment begins, the vibration motor 1 is started first. Vibration motor 1 drives the screen base 5, along with the circular screen 14, to move up and down via the crossbeam 2 and vertical arm 3, sieving the material according to the set particle size requirements. Then, a rotary motor is driven, which drives the base 9 to rotate horizontally. The base 9, through the support arm 7, drives the water tank 6 to rotate horizontally, causing relative movement between the mineral sample and water in the screen. The up-and-down vibration drive of the screen and the horizontal movement drive of the water tank do not interfere with each other, thus achieving both up-and-down movement and horizontal relative movement between the screen and water, thereby realizing the particle size sieving of the mineral sample. At this time, the material in the circular screen 14 completes the sieving under the combined action of up-and-down vibration and horizontal rotation.

[0031] After screening is completed, turn off the vibration motor and the rotary motor. First, loosen and lift the water tank cover plate 13 and rinse it with clean water. Then rinse the top of the screen cover plate 12 and the water baffle plate 11. At this time, the bottom flow valve 8 can be opened to discharge the screened product and rinse the screen bottom support and water tank 6.

[0032] Finally, after there are no water droplets at the bottom of the circular sieve, loosen and lift the sieve cover plate 12, rinse the bottom of the sieve cover plate 12, remove the circular sieve, rinse out the product on the sieve, and thus complete a single wet sieving process.

[0033] Through the above process, the sieve can make high-frequency, low-amplitude up-and-down movements, simulating a person shaking a sieve up and down in water. The sieve can also make horizontal circular movements, causing the water and the sieve to have lateral relative movements, simulating a person shaking a sieve laterally. By superimposing the two relative movements, the action of manually sieving mineral samples can be simulated.

[0034] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
