Description
Technical Field
The utility model relates to a beneficiation laboratory device, in particular to a solid-liquid slurry homogenizing and filtering device.
Background
In the scientific research and production practice of mineral separation and related industries, the solid-liquid slurry is often required to be homogenized and condensed to meet the requirements of research, production and detection. Currently, wet splitters are being used: 1. a wet splitter, i.e. a wet splitter that splits into two. When the wet-type riffle is used for scaling, the sample distribution uniformity can be influenced due to the fact that solid-liquid slurry is not uniformly fed into the sample distributor; in addition, if the sample is divided into a plurality of portions, the wet type riffle has the defects of complexity and low efficiency due to repeated operation. 2. The rotary sample divider has one divided part comprising one ore discharging port, one stirring barrel with equal interval and equal radius distribution around the stirring barrel, and one material receiving tank with constant rotation speed for the material to enter from the ore discharging port. There are disadvantages in that: a. the stirring barrel feeds materials in a rotating mode, the solid-liquid slurry amount and the liquid level in the stirring barrel change along with the discharge of the materials, the material discharge speed at a discharge port also changes, the solid-liquid slurry flow is unstable, and the sample separation uniformity is influenced; b. the stirring barrel feeds materials in a rotating mode, the feeding port and the receiving port are separated, and solid-liquid slurry is easy to splash; c. the material deposited in the discharge opening and the stirring barrel is more, if the material is separated after being washed, the influence on the properties of the solid-liquid slurry is larger, and the condition of uneven distribution also exists; 3. one sample dividing cone for more than one sample, and uniformly distributing the solid-liquid slurry which is uniformly stirred through the sample dividing cone. The sample-separating cone is required to be smooth in conical surface, the bottom surface of the cone is horizontal, solid-liquid slurry feeding is opposite to the cone top, and the solid-liquid slurry feeding is uniform along the circumferential direction of the conical surface. The method has the defects that solid-liquid slurry is fed to a conical top just right, and the uniform distribution along the circumferential direction of the conical surface is difficult, namely the problems of high requirement, complex operation and the like exist; 4. the mixing tank with a plurality of mixing tanks is matched with the sample separating plate, and the problems of high requirement, complex operation and the like exist. The above 4 methods all have the problem of inaccurate sample separation.
In summary, the existing wet sample splitter has the defects of inconvenient operation, unstable operation, poor sample splitting uniformity, large error, long sample splitting time and the like, and the number of the sample splitting time is more than 1 minute, so that the sample size after splitting can not be flexibly obtained on the premise of ensuring the representative requirement, and the application of the sample splitting machine in scientific research and production is influenced.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings:
as shown in fig. 1 and 2, a solid-liquid slurry homogenizing and filtering device comprises a motor 1, a motor bracket 2, a transmission rod 3, a feeding hopper 4, a distribution cone sleeve 5, a distribution cone sleeve bracket 6, a distribution cone 7, a buchner funnel 8 and a filter flask 11.
A filtering bottle rubber plug 10 is arranged at the bottle mouth of the filtering bottle 11, an opening corresponding to the funnel mouth of the Buchner funnel 8 is arranged at the center of the filtering bottle rubber plug 10, and the root of the funnel mouth of the Buchner funnel 8 can be inserted into the filtering bottle 11 from the opening. An air suction port 12 is arranged at the upper part of the suction bottle 11, and a filtrate discharge port 13 is arranged at the lower part of the suction bottle 11.
The distribution cone sleeve 5 is fixedly connected on a distribution cone sleeve support 6, and the lower part of the distribution cone sleeve support 6 is a circular ring base which can be arranged on the upper edge of a Buchner funnel 8.
The hopper 4 is fixed on top of the distribution cone sleeve 5 and communicates with the inside of the distribution cone sleeve 5. The interior of the dispensing cone sleeve 5 communicates with the interior of the buchner funnel 8. Inside buchner funnel 8 is provided with filter disc 9.
The distribution cone 7 is provided with two-stage step-shaped conical surfaces, and the distribution cone sleeve 5 is provided with two-stage step-shaped convex edges corresponding to the distribution cone sleeve.
The motor 1, the motor bracket 2, the transmission rod 3, the feeding hopper 4, the distribution cone sleeve 5, the distribution cone sleeve bracket 6 and the distribution cone 7 form a solid-liquid slurry homogenizing device.
The working principle and the working process of the utility model are as follows:
1. the filter flask 11 is placed on a stable operating platform, and the filter flask rubber plug 10 is sleeved into the root of the funnel mouth of the buchner funnel 8 and is plugged into the upper opening of the filter flask 11). The filtrate discharge port 13 is tightly plugged by a rubber plug, and the air exhaust port 12 is connected with a vacuum pump by a pressure-resistant rubber tube.
2. The filter paper is placed on the filter disc 9 of the buchner funnel 8, moistened with water if necessary, and the vacuum pump is started to bring the filter paper into close contact with the filter disc 9. Generally, the diameter of the filter paper is slightly larger than that of the filter disc 9, and the periphery of the wetted filter paper is tilted and tightly attached to the wall of the funnel, so that all filter cakes can be conveniently taken out after the filtration is finished.
3. The motor 1 is started, the distribution cone 7 is driven by the transmission rod 3 to rotate rapidly, and the solid-liquid slurry is slowly poured into the feeding hopper 4 at a constant speed.
When solid-liquid slurry enters the upper part of the distribution cone sleeve 5 from the feeding hopper, preliminary stirring is carried out under the driving of the transmission rod 3, the solid-liquid slurry flows downwards in a spiral flow manner, and the rotation speed is greater than the natural downward flow speed of the solid-liquid slurry, so that the preliminary mixing in the circumferential direction can be realized on the upper part of the distribution cone sleeve 5 by the solid-liquid slurry. In order to prevent the solid-liquid slurry from directly flowing out along the wall of the distribution cone sleeve 5 without homogenization, two-stage convex edges are arranged in the distribution cone sleeve 5 to ensure that the solid-liquid slurry falls on the conical surface of the distribution cone 7. In order to ensure that the solid-liquid slurry is fully and uniformly mixed along the circumferential direction, the distribution cone 7 is provided with two-stage conical surfaces. After flowing down from the upper part of the distribution cone sleeve 5, the solid-liquid slurry falls on the conical surface on the distribution cone 7, and due to the rapid rotation of the conical surface and the inertia effect of the solid-liquid slurry, the solid-liquid slurry is firstly distributed on the conical surface in the circumferential direction, and simultaneously moves outwards along the conical surface under the centrifugal effect and is dispersed on the wall of the distribution cone sleeve 5 along the tangential direction outside the conical surface. Because the rotating speed of the conical surface is far greater than the natural downward flow speed of the solid-liquid slurry, the solid-liquid slurry can be homogenized on the conical surface and the distribution cone sleeve 5, and even if the flow of the solid-liquid slurry is large, the solid-liquid slurry can be stirred and homogenized under the condition that no gap exists between the distribution cone 7 and the distribution cone sleeve 5. The solid-liquid slurry flows down to the lower conical surface of the distribution cone 7 along the wall of the distribution cone sleeve 5, similarly, the solid-liquid slurry is dispersed on the lower inner wall of the distribution cone sleeve 5 again by the rotating conical surface, and finally, the solid-liquid slurry homogenized for three times flows down to the filter paper, and a filter cake uniform along the circumferential direction is formed on the filter paper.
And when the water content in the filter cake is less and meets the requirement of subsequent division, closing the vacuum pump and standing.
4. And taking down the solid-liquid slurry homogenizing device, carefully lifting the filter paper at the periphery of the filter cake after air passes through the filter cake and enters the suction flask 11, reducing the negative pressure and loosening the filter paper, and taking out the filter cake. If the filter cake is thick and can not be directly extracted, the Buchner funnel 8 can be pulled out from the mouth of the filter flask 11 and then is turned upside down on a clean and flat working table, the Buchner funnel 8 is blown, the filter cake and the filter paper can fall on the working table, and the filter cake can be obtained by slightly removing the filter paper.
5. The filtrate discharge port 13 at the lower part of the filter flask 11 is opened, and the filter flask 11 is tilted, so that the filtrate 14 can be completely discharged.
6. And (5) finishing the filtering device, and completely finishing the filtering operation.
The present invention can divide a solid-liquid slurry into a plurality of small samples which are representative in terms of mass, concentration, grain size composition and chemical composition. The method can conveniently, quickly and accurately carry out one-to-many separation on the solid-liquid slurry, and meets the requirements of research, production and detection. The utility model has simple structure, low manufacturing cost, convenient operation, uniform and accurate sample division, can equally divide samples, can take any amount within the total amount of the samples and does not need washing water; the utility model has strong practicability and adaptability and can be widely applied to scientific research and production.
