Description
Technical Field
[0001] The utility model belongs to the technical field of copper smelting ore dressing, and relates to a measuring tool for the pulp concentration and fineness of copper smelting slag ore dressing. Background Art
[0002] Industrial solid waste by-products will be formed during copper smelting production, and copper smelting tailings are one of them. The flotation method has the advantages of low energy consumption, high efficiency, and convenient comprehensive resource recovery, and has become the main method for treating copper smelting tailings at present.
[0003] During the ore dressing process of the flotation method, there are differences in the technological process and equipment used among different units. However, the accuracy and timeliness of the pulp concentration and fineness measurement play a key role in the quality of the flotation index. Therefore, during the production process, operators need to frequently measure the pulp concentration and fineness.
[0004] At present, the pulp concentration and fineness are usually measured separately. Generally, a concentration pot is used to measure the pulp quality, and then the pulp concentration can be obtained by querying the pulp concentration, density, and mass conversion table. For the pulp fineness, the wet quick screening method is used for measurement. Separately measuring the pulp concentration and fineness is, on the one hand, more cumbersome and has low efficiency. On the other hand, the pulp and ore particles need to be frequently transferred, resulting in a large amount of material loss and a large measurement error.
[0005] At the same time, due to the high frequency of pulp concentration and fineness measurement, the portability and ease of use of the pulp concentration and fineness measurement tool should also be fully considered.
[0006] Therefore, it is necessary to provide a measuring tool for the pulp concentration and fineness of copper smelting slag ore dressing, which reduces the cumbersome degree of the measurement process and improves the measurement efficiency on the basis of making the tool portable and easy to use. Summary of the Utility Model
[0007] In order to overcome the problems in the background art, the utility model provides a measuring tool for the pulp concentration and fineness of copper smelting slag ore dressing. By simplifying the tool structure, the tool is easy to carry and use. Moreover, by using the tool, the pulp concentration and fineness can be measured simultaneously, reducing the cumbersome degree of the measurement process and improving the measurement efficiency.
[0008] To achieve the above object, the utility model is realized by the following technical solutions:
[0009] The tool includes a kettle body 1, an overflow pipe 2, a sieve 3, a handle 4, an annular mesh support 6, and a stainless steel ring 7. The overflow pipe 2 is fixedly arranged on the side wall of the kettle body 1 and is located at the upper part of the kettle body 1. The handle 4 is fixedly arranged on the side wall of the kettle body 1. The annular mesh support 6 covers the top of the kettle body 1. The sieve 3 is a cylindrical structure with one end open and composed of a sieve mesh. The open end of the sieve 3 is fixedly connected to the bottom of the annular mesh support 6 through the stainless steel ring 7. The height of the connection between the stainless steel ring 7 and the sieve 3 is not higher than the lowest point height of the overflow pipe 2. The diameter of the sieve 3, the diameter of the stainless steel ring 7, and the inner ring diameter of the annular mesh support 6 are the same. The axes of the sieve 3, the stainless steel ring 7, and the annular mesh support 6 coincide.
[0010] Preferably, the outer ring diameter of the annular mesh support 6 is equal to the diameter of the kettle body 1, and a mesh support handle 5 is fixedly arranged on the outer ring edge of the annular mesh support 6.
[0011] Preferably, there are 2 mesh support handles 5, and the positions of the 2 mesh support handles 5 are symmetrically distributed with respect to the diameter of the annular mesh support 6 as the axis of symmetry.

[0022] In the figure, 1 is the kettle body, 2 is the overflow pipe, 3 is the sieve, 4 is the handle, 5 is the handle of the mesh support, 6 is the annular mesh support, and 7 is the stainless steel ring. Specific embodiments
[0023] The present utility model will be further described in detail below in conjunction with specific embodiments.
[0024] As Figures 1-3 shown, the tool includes a kettle body 1, an overflow pipe 2, a sieve 3, a handle 4, an annular mesh support 6, and a stainless steel ring 7. The overflow pipe 2 is fixedly arranged on the side wall of the kettle body 1 and is located at the upper part of the kettle body 1. The handle 4 is fixedly arranged on the side wall of the kettle body 1. The annular mesh support 6 covers the top of the kettle body 1. The sieve 3 is a cylindrical structure with one end open and made of a sieve mesh. The open end of the sieve 3 is fixedly connected to the bottom of the annular mesh support 6 through the stainless steel ring 7. The height of the connection between the stainless steel ring 7 and the sieve 3 is not higher than the lowest point height of the overflow pipe 2. The diameter of the sieve 3, the diameter of the stainless steel ring 7, and the inner ring diameter of the annular mesh support 6 are the same. The axes of the sieve 3, the stainless steel ring 7, and the annular mesh support 6 coincide.
[0025] For the measurement results of the pulp concentration and fineness, they are all the proportion of ore particles with a particle size greater than or equal to a certain preset value in the pulp. Therefore, before measurement, the preset value can be determined according to the actual situation, and thus a sieve 3 with an appropriate sieve hole diameter can be selected for measurement. When using the tool, pulp or clean water can be injected into the cylindrical sieve 3 through the inner ring opening of the annular mesh support 6. When injecting clean water, the clean water directly flows into the kettle body 1 through the sieve 3. When injecting pulp, since the pulp contains ore particles with different particle sizes, the ore particles with a particle size greater than the sieve hole diameter of the sieve 3 cannot pass through the sieve 3 and remain in the sieve 3, while the liquid and the ore particles with a particle size smaller than the sieve hole diameter of the sieve 3 flow into the kettle body 1 through the sieve 3. The staff can hold the handle 4 to conveniently pour the liquid in the kettle body 1 and transfer the kettle body 1. At the same time, as the amount of liquid injected into the kettle body 1 increases, the liquid level rises, and the liquid will flow out of the kettle body from the overflow port 2, so that the volume of the added liquid is controlled, and the difference in the volume of the added liquid each time is small, and finally the measurement result has a high accuracy. In order to facilitate the staff to remove the annular mesh support 6, an annular mesh support 6 with an outer ring diameter larger than the diameter of the kettle body 1 can be selected.
[0026] The surface of the stainless steel ring 7 is smooth. When pulp is injected into the sieve 3, the ore particles in the pulp will not adhere to the surface of the stainless steel ring 7 when they come into contact with it, but will enter the liquid. The ore particles themselves have a certain volume. If the ore particles do not enter the liquid, in the case of the same volume, the mass of the liquid phase in the liquid will increase, and the overall weight of the pulp and the tool will rise, resulting in a lower measurement result accuracy. Therefore, when adding pulp until the liquid flows out of the overflow pipe 2, the liquid level is at the lowest point of the overflow pipe 2. When the height of the connection between the stainless steel ring 7 and the sieve 3 is not higher than the lowest point of the overflow pipe 2, the sieve 3 can be fully immersed in the liquid, preventing ore particles from adhering to the sieve 3 that is not immersed in the liquid and affecting the measurement result accuracy.
[0027] The outer diameter of the outer ring of the annular mesh support 6 is equal to the diameter of the kettle body 1, and a mesh support handle 5 is fixedly arranged on the outer ring edge of the annular mesh support 6.
[0028] When the outer diameter of the outer ring of the annular mesh support 6 is equal to the diameter of the kettle body 1, the mesh support handle 5 is set, which is convenient for the staff to hold the mesh support handle 5, so as to remove the annular mesh support 6 from the kettle body 1.
[0029] There are 2 mesh support handles 5, and the positions of the 2 mesh support handles 5 are symmetrically distributed with the diameter of the annular mesh support 6 as the axis of symmetry.
[0030] If there are more ore particles and greater weight in the sieve 3, the 2 mesh support handles 5 allow the staff to hold the mesh support handles 5 with both hands at the same time, and then smoothly remove the annular mesh support 6.
[0031] The length of the overflow pipe 2 is greater than 50 mm.
[0032] When adding a certain amount of liquid into the kettle body 1, the liquid will flow out of the overflow pipe 2. The longer length of the overflow pipe 2 can make the position of the liquid outlet farther from the kettle body 1, reducing the possibility of the poured liquid splashing onto the kettle body 1. Since the pulp is a mixture of mud and water, when the pulp splashes onto the kettle body 1, it will adhere to the kettle body 1, causing the overall weight of the kettle body to increase. And the final measurement result of the pulp fineness is related to the weight of the kettle body 1. Reducing or avoiding the amount of liquid adhering to the outside of the kettle body 1 helps to improve the accuracy of the final measurement result.
[0033] The distance between the side wall of the sieve 3 and the inner side wall of the kettle body 1, and the distance between the bottom surface of the sieve 3 and the bottom surface of the kettle body 1 are both 10 - 20 mm. The smaller the distance between the sieve 3 and the side wall and bottom surface of the kettle body 1, the larger the surface area of the sieve 3. With the same sieve hole diameter, the number of sieve holes is also more. The more channels for ore particles with a particle size smaller than the sieve hole diameter to flow out of the sieve 3, which is beneficial to improving the screening efficiency. However, the sieve 3 cannot be closely attached to the side wall and bottom surface of the kettle body 1. When the sieve 3 is closely attached to the side wall and bottom surface of the kettle body 1, the sieve 3 must be taken out to achieve the screening effect. When the sieve 3 is immersed in the liquid, it does not have the screening effect, affecting the normal use of the sieve 3. Therefore, controlling the distance between the side wall and bottom surface of the sieve 3 and the side wall and bottom surface of the kettle body 1 within a small range can improve the screening efficiency and enable the sieve 3 to fully exert its screening effect.
[0034] The positions of the overflow pipe 2 and the handle 4 are located on opposite sides of the kettle body 1. It can be operated with one hand, which is more convenient and more in line with the conventional use habits.
[0035] The working process of the present utility model: When it is necessary to measure the pulp concentration and fineness, first cover the annular mesh support with the kettle body. At this time, there is no liquid in the kettle body and no ore particles in the sieve. Weigh the weight of the empty kettle G0. Then, pour clear water into the kettle body until water flows out from the overflow pipe, and then weigh the overall weight of the tool at this time G1. Then pour out the clear water, add pulp into the sieve. The ore particles with a particle size larger than the sieve hole diameter in the pulp cannot pass through the sieve and remain in the sieve. The liquid and the ore particles with a particle size smaller than the sieve hole diameter of the sieve flow out of the sieve and enter the kettle body. Add pulp until pulp flows out from the overflow pipe, and weigh the overall weight of the tool at this time G2. Then remove the annular mesh support. At this time, the sieve is also taken out from the kettle body. Pour out all the liquid in the kettle body, add clear water into the kettle body again, and cover the annular mesh support on the kettle body again. The sieve is immersed in the clear water to repeatedly screen the ore particles in the sieve. During the repeated screening process, according to the turbidity of the liquid in the kettle body, replace the clear water in time until the liquid in the kettle body is clear and all the ore particles inside the sieve 3 are those with a particle size larger than the sieve hole diameter. After the repeated screening is completed, remove the annular mesh support, pour out the liquid in the kettle body, clean and dry the kettle body and the annular mesh support, then cover the annular mesh support on the kettle body again, and inject clear water into the kettle body through the inner ring opening of the annular mesh support until liquid flows out from the overflow pipe, and weigh the overall weight of the tool at this time G3. According to the formula P = Calculate the pulp concentration P, where δ is the ore particle density, with the unit of g / cm 3 , V is the volume of the pulp in the kettle body. According to the formula Calculate the pulp fineness R. Then the measurement of the pulp concentration and fineness is completed. The aforementioned calculation formulas and working processes are obtained in accordance with relevant standard specifications and belong to conventional operations.
[0036] When the utility model tool is actually used, the position of the overflow pipe is determined, the distance between the overflow pipe and the bottom of the kettle body is determined, and at the same time the size of the kettle body is determined. Then, the volume of the kettle body below the position of the overflow pipe can be measured by adding clean water into the kettle body. When adding pulp, it is also added until the pulp flows out of the overflow pipe. Then, the volume of the kettle body is the volume V of the pulp.
[0037] When the utility model tool has not been used for a period of time, before using it again, it is necessary to weigh G0 and G1 for recheck. If the recheck error is within the required range, the same tool can be continued to be used for measuring the fineness of pulp concentration. If the recheck error exceeds the required range, it means that this tool is not suitable for use itself. Then, another tool is used for measuring the fineness of pulp concentration.
[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in terms of form and details without departing from the scope defined by the claims of the present invention.
