Description

Technical Field

[0001] This utility model relates to the field of geological powder sample sieving technology, and in particular to a wet sieving instrument for geological powder samples. Background Technology

[0002] A wet sieve analyzer is a device that uses water rinsing or a combination of mechanical vibration to sieve the material to be tested through a sieve, separating it into particles of different sizes. The particle size distribution curve and related parameters are then calculated based on the sieve results.

[0003] Traditional laboratory wet sieving instruments, such as the Tyler RX-29-10 vibrating sieve from the USA, are primarily designed for small sample sizes. This instrument performs well in separating particles from small, well-dispersed samples. However, when dealing with geological powder samples, especially those with high clay content such as paleosols, lacustrine sediments, and marine sediments, where sample dispersibility is poor, this instrument cannot guarantee satisfactory sieving results. Furthermore, laboratory sorting requires significant water intake and drainage, and this device is also unsuitable for such conditions. Utility Model Content

[0004] The purpose of this invention is to provide a wet sieve for geological powder samples, which can disperse the material before sieving to ensure sufficient sieving. It also supplies water to the sample sieve above and below the main body of the wet sieve at the same time, and can be used for clay minerals with large sample volume that are difficult to disperse.

[0005] To achieve the above objectives, a wet sieving instrument for geological powder samples is provided, comprising a worktable. A base, a controller, a feed pump, a stirring mechanism, and the main body of the wet sieving instrument are fixedly connected to the upper end of the worktable. A second feed pipe is fixedly connected to the bottom of the stirring mechanism, and the other end of the second feed pipe is fixedly connected to the input end of the feed pump. A first feed pipe is fixedly connected to the output end of the feed pump, and the other end of the first feed pipe extends above the main body of the wet sieving instrument and opens downwards. A water tank and a water pump are fixedly connected to the upper end of the base. The water pump's inlet is connected to the water tank, and the water pump's outlet is fixedly connected to a water distribution valve. The water distribution valve has two outlets, an upper outlet and a lower outlet. The upper outlet of the water distribution valve is fixedly connected to a water supply pipe, and the end of the water supply pipe furthest from the water distribution valve is installed on the top of the wet sieve body. The lower outlet of the water distribution valve is fixed to the surface of the wet sieve body and connected to it. First stop valves are fixedly connected to the top of the water tank and the bottom outlet of the wet sieve body. Support legs are fixedly connected to the four corners of the lower end of the workbench. This design allows for the dispersion of materials before sieving, ensuring thorough sieving. Furthermore, it simultaneously supplies water to both the upper and lower parts of the sample sieve within the wet sieve body, making it suitable for large quantities of clay minerals that are difficult to disperse.

[0006] According to the geological powder sample wet sieving instrument, a second stop valve is installed between the water tank and the water pump, and between the lower end of the water distribution valve and the main body of the wet sieving instrument. The second stop valve controls the water outlet from the water tank and the water outlet from the lower end of the water distribution valve.

[0007] According to the described wet sieving instrument for geological powder samples, the main body of the wet sieving instrument consists of sample sieves, an equipment shell, a vibrating base, and telescopic supports. The vibrating base is installed on the upper part of the worktable. Two telescopic supports are symmetrically fixed to the upper part of the vibrating base, and a fastening plate is fixedly connected to the telescopic supports. The equipment shell is located between the two telescopic supports and above the vibrating base. The fastening plate is fixedly connected to the top of the equipment shell. A first support rod is fixedly connected to the upper part of the vibrating base. An electric push rod is fixedly connected to the upper part of the first support rod. A mounting plate is fixedly connected to the upper part of the electric push rod. A rotary nozzle passes through the end of the mounting plate away from the electric push rod, and one end of the water supply pipe is fixedly connected to the rotary nozzle. Multiple sample sieves are installed equidistantly in the equipment shell. The lower end of the water distribution valve is connected to the equipment shell and is located below the sample sieves. A water outlet is provided on one side of the bottom of the equipment shell. The telescopic supports install the equipment shell on the vibrating base. The vibrating base vibrates and drives the equipment shell to vibrate, and the sample sieves sieve the geological powder samples.

[0008] According to the described wet sieving instrument for geological powder samples, the stirring mechanism consists of a support frame, a stirrer, a stirring paddle, a second support rod, and a stirring motor. The second support rod is fixedly connected to the bottom of the stirrer. Both the second support rod and the support frame are fixedly connected to the upper part of the worktable, with the support frame located on one side of the stirrer. The stirring motor is fixedly connected to the top of the support frame and is located above the middle of the stirrer. The rotating shaft of the stirring motor is fixedly connected to the stirring paddle, and the top of the stirring paddle passes through the support frame and is rotatably connected to it. The stirring paddle extends into the stirrer and is located in the middle of the stirrer. A solenoid valve is fixedly connected to the bottom of the stirrer, and the bottom of the solenoid valve is fixedly connected to the second feed pipe. Several ultrasonic transducers are equidistantly embedded in the inner wall of the stirrer. The stirring paddle and the ultrasonic transducers work together to disperse the material in the stirrer, improving the dispersion effect.

[0009] According to the described wet sieving instrument for geological powder samples, a collector is installed on the side of the vibrating seat. The collector is used to collect the sample discharged from the main body of the wet sieving instrument. The collector collects the sample of the smallest particle size group sieved out by the main body of the wet sieving instrument.

[0010] According to the described wet sieving instrument for geological powder samples, the controller includes an ultrasonic generator and a control panel. The ultrasonic generator converts mains power (220V or 380V, 50 or 60Hz) into a high-frequency AC signal that matches the ultrasonic transducer, which then emits ultrasonic waves. The control panel controls components in the device, including the first stop valve, feed pump, water pump, second stop valve, water distribution valve, vibrating seat, electric push rod, solenoid valve, and stirring motor.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] 1. The ultrasonic waves emitted by the stirring paddle and ultrasonic transducer in the stirring mechanism disperse the material before screening, ensuring sufficient screening.

[0013] 2. The water pump supplies water from both above and below the sample sieve in the main body of the wet sieve through the water distribution valve. While ensuring that the wet sieve can sieve the sample, it also washes the sample of the smallest particle size group screened out from the bottom of the wet sieve out of the equipment, so that the device can be used for clay minerals with large sample volume and difficult dispersion.
