[0017] The embodiment of the present application provides a binary three-stage reducer, which effectively solves the problem that when a grid-type binary single-stage reducer is used to reduce a solid-liquid mixture sample, multiple reductions and repeated operations are required to obtain the required sample, resulting in high labor intensity, low reduction efficiency, and poor representativeness of the retained samples. The binary three-stage reducer is particularly suitable for reducing solid-liquid mixture samples (such as flotation slurry) and has the function of filtering out most of the liquid by gravity. Each sample preparation personnel only needs to pour the sample to be reduced once to complete the sample reduction task. Compared with the original single-stage reduction device, the labor intensity of the personnel is reduced, the efficiency of the sample preparation work is improved, and the samples retained or discarded after reduction have the same representativeness and effectiveness.
[0018] Example: Figure 1 、 Figure 2 and Figure 3As shown, the technical solution in the embodiment of the present application effectively solves the technical problems of high labor intensity, low reduction efficiency and poor representativeness of retained samples when a grid-type binary separation single-stage reducer is used to reduce a solid-liquid mixture sample, requiring multiple reductions and repeated operations to obtain the required sample. The overall idea is as follows:
[0019] In view of the problems existing in the prior art, the present invention provides a binary three-stage reducer, comprising a base 1, a frame plate 11 is fixedly installed on both sides of the upper end of the base 1, and a first-stage reduction groove 2, a second-stage reduction groove 3 and a third-stage reduction groove 4 are installed between the two frame plates 11 from top to bottom. A cylinder 6 is installed on the frame plate 11 on the right side, and a telescopic rod of the cylinder 6 is fixedly connected to a sample injection tube 5. A guide rail 7 is provided below the sample injection tube 5, and the guide rail 7 is located above the first-stage reduction groove 2. The guide rail 7 is fixed to the first stage reduction groove 2. It is fixedly installed between the two racks 11. Drain plates 8 are provided below the first-stage reduction trough 2, the second-stage reduction trough 3 and the third-stage reduction trough 4, and are distributed on the front and back sides. Each drain plate 8 is fixedly installed between the two racks 11. The sample feeding tube 5 can slide along the length direction of the guide rail 7 to transfer samples. A sample receiving screen 9 is placed on the base 1. The sample receiving screen 9 is located below the third-stage reduction trough 4. Filter paper is placed in the sample receiving screen 9 to retain the sample and perform natural dehydration and filtration under the action of gravity. The four corners of the bottom end of the base 1 are fixedly connected to support feet, and each frame 11 is of stepped design. The cylinder 6 pushes the sampling tube 5 to move left and right, and the solid-liquid mixture (such as flotation pulp) sample in the sampling tube 5 randomly falls into the first-stage reduction tank 2. The retained sample after the first-stage reduction enters the second-stage reduction tank 3. The retained sample after the second-stage reduction enters the third-stage reduction tank 4. The retained sample after the third-stage reduction enters the sample receiving screen 9 and accumulates on the filter paper of the sample receiving screen 9. The discarded samples generated by each stage of reduction all enter the collection area through the drainage plate 8. This binary three-stage reducer is particularly suitable for the reduction of solid-liquid mixture samples (such as flotation pulp) and has the function of filtering out most of the liquid by gravity. Each sample preparation personnel only needs to pour the sample to be reduced once to complete the sample reduction task. Compared with the original single-stage reduction device, the labor intensity of the personnel is reduced, the sample preparation efficiency is improved, and the samples retained or discarded after reduction have the same representativeness and effectiveness.
[0020] Working principle:
[0021] In the first step, the cylinder 6 pushes the sampling tube 5 to move left and right, and the solid-liquid mixture (such as flotation pulp) sample in the sampling tube 5 randomly falls into the first-stage reduction tank 2, and the retained sample after the first-stage reduction enters the second-stage reduction tank 3. The retained sample after the second-stage reduction enters the third-stage reduction tank 4. The retained sample after the third-stage reduction enters the sample receiving screen 9 and accumulates on the filter paper of the sample receiving screen 9. The discarded samples generated by each stage of reduction all enter the collection area through the drainage plate 8. This binary three-stage reducer is particularly suitable for the reduction of solid-liquid mixture (such as flotation pulp) samples, and has the function of filtering out most of the liquid by gravity. Each sample preparation personnel only needs to pour the sample to be reduced once to complete the sample reduction task. Compared with the original single-stage reduction device, the labor intensity of the personnel is reduced, the efficiency of the sample preparation work is improved, and the samples retained or discarded after reduction have the same representativeness and effectiveness.
