Description

Technical Field

[0001] The present application belongs to the technical field of analytical sampling technology, and in particular relates to a quantitative sampler for solid-liquid mixed slurry. Background Art

[0002] Solid-liquid mixing refers to the process of mixing solid particles with a liquid to form a uniformly distributed mixture. For example, in alumina production, ore is ground and mixed with alkaline solution to form a solid-liquid slurry. The solid content of the slurry is adjusted according to production needs, so measuring the solid content of the slurry is a key analytical task in alumina production. Since the particle size of the ground ore is approximately 0.03-0.9mm and the density is approximately 2.3-3.5g / cm³, while the density of the alkaline solution commonly used in alumina production is between 1.2-1.35g / cm³, the ore density is much greater than the alkaline solution density, causing the ore particles to quickly sink to the bottom of the solution (similar in nature to a slurry of water and sand).

[0003] The existing sampling and analysis method is: when sampling, open the sampling valve, fill the sampling cylinder with slurry to about 2 / 3 of the position, and send it to the analysis site. During analysis, since the ore particles have sunk to the bottom of the cylinder, the slurry must first be stirred evenly with a stirring rod, and then the slurry is poured into a measuring cylinder, 50 mL is measured, and then the 50 mL slurry in the measuring cylinder is washed, dried, weighed, and the solid content is calculated. However, this sampling method is prone to analytical errors. Utility Model Content

To this end, the present application provides a quantitative sampler for solid-liquid mixed slurry, which can directly and quickly analyze the solid-liquid mixed slurry without being affected by the sedimentation of solid phase particles. The analysis results have small errors and are close to the actual situation. It is also simple to use and convenient to carry.

[0009] In an optional embodiment, the inner cover body has an outer cover edge, and when the inner cover body is connected to the inner body, the outer cover edge is attached to the outer wall of the inner body.

[0027] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0028] Please refer to Figure 1 In an embodiment of the present application, a quantitative sampler for solid-liquid mixed slurry is provided, which includes a first sampling container 110 and a second sampling container 120. On the basis of existing structures such as measuring cups, it is improved to a double-layer combination container structure based on quantitative containers. Both the first sampling container 110 and the second sampling container 120 can be loaded with solid-liquid mixed slurry, and sampling and analysis are performed only through the second sampling container 120. The first sampling container 110 has a accommodating space 110a inside. For example, if the accommodating space 110a is opened inwardly at the top of the first sampling container 110, the accommodating space 110a can be loaded with solid-liquid mixed slurry; the volume of the second sampling container 120 is smaller than that of the first sampling container 110. The second sampling container 120 can be placed in the first sampling container 110. The second sampling container 120 has a quantitatively specified space for loading solid-liquid mixed slurry. For example, if the top of the second sampling container 120 opens a space inwardly, the space is used to load solid-liquid mixed slurry. It should be noted that the volume of the entire space is The volume is of quantitative specification, that is, the amount of solid-liquid mixed slurry filled in the second sampling container 120 meets the detection requirements and can be directly tested. The second sampling container 120 is used to be placed in the accommodating space 110a. When the second sampling container 120 is placed in the accommodating space 110a, there is a gap 110b between the first sampling container 110 and the second sampling container 120. The gap 110b can accommodate the solid-liquid mixed slurry. In this way, after the second sampling container 120 is filled with the solid-liquid mixed slurry, it can continue to receive a part of the solid-liquid mixed slurry, and the excess part flows into the above-mentioned gap 110b position.

[0029] The existing sampling and analysis containers are relatively simple and only have the function of containing. However, sampling and analysis are prone to errors. This is caused by the rapid sedimentation of solid particles. For example, the density of the ore is large and the sedimentation rate is fast. When stirring, it is sometimes impossible to stir the slurry evenly. At the same time, the slurry is still settling. The part directly poured from the container containing the slurry into the measuring cylinder cannot reflect the actual situation, which affects the solid content analysis results and is prone to analytical errors. In addition, when the slurry is poured into the measuring cylinder, it is necessary to observe the liquid level of the measuring cylinder. The pouring of the slurry must be stopped first, and then the liquid level of the measuring cylinder is observed. If the detection amount is not met, the container will be poured a second time according to the liquid level of the measuring cylinder, resulting in secondary sedimentation of the slurry. A second stirring is required before the slurry can be poured again, which will also increase the analysis error and increase the workload.

[0030] In the present application, the solid-liquid mixed slurry to be tested is loaded into the second sampling container 120. The second sampling container 120 can be placed in the accommodating space 110a of the first sampling container 110. The accommodating space 110a and the second sampling container 120 can both be loaded with the solid-liquid mixed slurry. Since the second sampling container 120 is of quantitative specification, the second sampling container 120 can always maintain a quantitative solid-liquid mixed slurry and is not affected by the first sampling container 110. The second sampling container 120 can be taken out from the first sampling container 110 alone and can be tested and analyzed after being taken out. In this way, the solid-liquid mixed slurry in the second sampling container 120 always maintains the same solid phase content as the original mixed liquid and is not affected by the sedimentation of solid phase particles. The error of the analysis result is small and close to the actual situation. At the same time, the present application directly eliminates the operation of quantitative liquid extraction and the operation of stirring and mixing. After taking out the second container, the solid-liquid mixed slurry can be directly and quickly analyzed. It is simple to use and convenient to carry.

[0031] In an optional embodiment, the second sampling container 120 includes an inner cover 122 and an inner body 121 made of a transparent material. The transparent container is used to facilitate observation of the solid-liquid mixed slurry. The inner body 121 is used to load the solid-liquid mixed slurry, and the inner cover 122 is used to seal the solid-liquid mixed slurry in the inner body 121. The inner cover 122 and the inner body 121 are detachably connected. The solid-liquid mixed slurry can be isolated by the inner cover 122 to avoid the influence of other factors of the experiment; the inner body 121 is cylindrical with an open top and a closed bottom. The inner diameter of the internal space of the inner body 121 is φ5 cm, the outer diameter is φ5.3 cm, the volume is 200 mL, the inner body 121 is 10.2 cm high, and the inner cover 122 is in the shape of a circular cover. The bottom of the inner cover 122 can just be sealed with the opening of the inner body 121. In an optional embodiment, the inner cover 122 has an outer cover edge. When the inner cover 122 is connected to the inner body 121, the outer cover edge is attached to the outer wall of the inner body 121. For example, a circular outer cover edge extends downward from the bottom of the inner cover 122. The inner diameter of the outer cover edge matches the outer diameter of the opening of the inner body 121, so that the inner cover 122 can just cover the opening of the inner cover 122, forming an outer buckle shape. The diameter of the inner cover 122 is φ6 cm, the outer cover edge is 0.5 cm long, and the inner diameter of the outer cover edge is φ5.3 cm. The quantitative specification space setting of the second sampling container 120 can be loaded with a fixed volume of solid-liquid mixed slurry. The capacity is determined during analysis. When sampling, all the slurry in the inner body 121 is washed, dried, and weighed, avoiding stirring errors and pouring errors, and reducing volume errors. The solid-liquid mixed slurry in the first sampling container 110 can be used for other analytical activities such as solution analysis.

[0032] In an optional embodiment, the first sampling container 110 includes an outer cover 112 and an outer body 111 made of a transparent material. The transparent container is used to facilitate observation of the solid-liquid mixed slurry. The inner diameter of the outer body 111 is φ8 cm and the height is 12 cm. The accommodating space 110a inside the outer body 111 is used to load the inner body 121 and the solid-liquid mixed slurry. The outer cover 112 is used to seal the inner body 121, the inner cover 122 and the solid-liquid mixed slurry in the outer body 111. The outer cover 112 is detachably connected to the outer body 111. The second sampling container 120 can be isolated from the outside through the outer cover 112 to avoid being affected by other factors of the experiment; the outer body 111 is cylindrical with an open top and a closed bottom. The inner diameter of the accommodating space 110a of the outer body 111 is φ8 cm and the volume is 500 mL. The outer cover 112 is in the shape of a circular cover, and the bottom of the outer cover 112 can just be closed with the opening of the outer body 111. In an optional embodiment, the outer cover body 112 has an inner cover edge. When the outer cover body 112 is connected to the outer body 111, the inner cover edge is attached to the inner wall of the outer body 111, such as a circular inner cover edge extending downward from the bottom of the outer cover body 112, and the outer diameter of the inner cover edge matches the inner diameter of the opening of the outer body 111, so that the outer cover body 112 can just cover the opening of the outer cover body 112, forming an inward buckle form. The diameter of the outer cover body 112 is φ8.5 cm, the outer cover edge is 2.5 cm long, and the outer diameter of the outer cover edge is φ8 cm.

[0033] Please refer to Figure 2 In an optional embodiment, a limiting member 130 is further included. The second sampling container 120 and the first sampling container 110 are detachably connected via the limiting member 130. The limiting member 130 is connected to the outer body 111 and is located in the accommodating space 110a. The limiting member 130 is used to clamp the inner body 121. For example, the limiting member 130 is annular and is fixed to the inner bottom wall of the outer body 111 by gluing. A circular space is formed on the inner side of the limiting member 130, and the outer wall bottom of the inner body 121 can be just stuck into the circular space and fixed. When sampling, the inner body 121 can be directly taken out. In an optional embodiment, the limiting member 130 includes a plurality of limiting plates 131, which are spaced apart on the inner body 121, and a bayonet for clamping the inner body 121 is formed between the plurality of limiting plates 131; for example, there are eight limiting plates 131, which are radially distributed, and the limiting plates 131 are right-angled trapezoidal plates, and the dimensions of the trapezoid are: the long side is 2 cm, the short side is 1 cm, the right-angled side is 1 cm, and the angle between the hypotenuse and the long side is 45 degrees. Limiting plates 131 of other shapes and sizes can also be used. The right-angled sides of the limiting plates 131 are bonded to the bottom of the outer body 111, with the long side on the outside and the short side on the inside. The position of the short side can form a circle with an inner diameter of 5.4 cm. The circular area can clamp the outer wall of the inner body 121, so that after the inner body 121 is placed in the accommodating space 110a, it is fixed by multiple limiting plates 131.

[0034] In an optional embodiment, an overflow port 114 is further included, connected to the outer body 111. The overflow port 114 connects the accommodating space 110a with the outer side of the outer body 111. The height of the overflow port 114 is higher than that of the inner body 121. The overflow port 114 and the outer body 111 can be integrally formed, or a through-hole can be provided in the upper side wall of the outer body 111, with one end of the overflow port 114 connected to the through-hole and secured by gluing, screwing, or other means. For example, the height of the overflow port 114 from the bottom of the outer body 111 is 10.2 cm, and the width of the overflow port 114 is 1.5 cm. The overflow port 114 is tubular, hollow inside, and connects the accommodating space 110a with the outer side of the outer body 111.

[0035] In an optional embodiment, the first sampling container 110 further includes an outer operating end 113 connected to the outer cover 112; the second sampling container 120 further includes an inner operating end 123 connected to the inner cover 122. The inner operating end 123 and the outer operating end 113 are both raised cylindrical structures, such as lid twists. The height of the inner operating end 123 and the outer operating end 113 are both 1.5 cm. The inner operating end 123 facilitates the removal of the inner cover 122 from the inner body 121, and the outer operating end 113 facilitates the removal of the outer cover 112 from the outer body 111. In an optional embodiment, the first sampling container 110 further includes a handle 115 connected to the outer wall of the outer body 111. The handle 115 and the outer body 111 can be integrally formed, or the handle 115 can be fixed to the outside of the outer body 111 using screws. Other fixing methods can also be used. In an optional embodiment, the overflow port 114 is located at a position opposite to the handle 115 , so that the solid-liquid mixed slurry in the first sampling container 110 can be easily poured out by operating the handle 115 .

[0036] The usage method of the present application is: first, rinse the inner body 121 and the outer body 111 with water; then remove the outer cover 112 and the inner cover 122, take out the inner body 121, open the slurry sampling valve, and rinse the inner body 121 and the outer body 111 twice respectively with slurry; then place the inner body 121 in the middle of the limit plate 131 inside the outer body 111 and fix it; then open the slurry sampling valve, hold the quantitative sampler 100 horizontally, and use the center of the quantitative sampler 100 to collect the slurry until the slurry flows out from the overflow port 114; then close the slurry sampling valve, and cover the inner cover 122 and the outer cover 112 in turn; send the quantitative sampler 100 to analysis, open the outer cover 112, take out the inner body 121, open the inner cover 122, and pour out all the slurry in the inner body 121 for solid content washing, drying, weighing, and calculation and analysis. Since the capacity of the inner body is fixed, there is no need for stirring, secondary pouring and liquid level observation in traditional analysis, and the operation after washing can be carried out directly, thereby reducing the error of the analysis process. The remaining slurry in the outer body 111 can be used for solution analysis.
