Description

Technical Field

[0001] The utility model mainly relates to the field of pulp concentration detection equipment, and specifically to a pulp concentration sampling device. Background Art

[0002] Minerals, as non-renewable resources, play a quite important role in social and economic development. Pulp concentration plays an extremely important role in the entire beneficiation process. It directly affects various technical and economic indicators of the beneficiation process. During the beneficiation process, the control of pulp concentration is crucial. Pulp concentration directly affects the beneficiation efficiency and the quality of the final product. In order to ensure the stability of the beneficiation process and the product quality, it is necessary to accurately measure the solid content in the pulp, that is, the so-called pulp concentration. This is usually achieved by taking samples regularly and conducting laboratory analysis. Sampling is to obtain samples that can represent the characteristics of the entire pulp system. These samples will be used for subsequent concentration measurement. If the sampling is improper, it may lead to incorrect concentration readings, which in turn affect the adjustment and optimization of the beneficiation process. For example, if there are particles with different densities in the pulp, they may stratify due to gravity, or due to the turbulent effect caused by pumping, the solid content in some areas may be different from that in other areas. Therefore, a method and device are needed to make the pulp more stable during the sampling process, so that sampling at multiple positions in multiple pulps can be carried out more efficiently and conveniently. Content of the Utility Model

[0003] To solve the deficiencies of the prior art, the utility model provides a pulp concentration sampling device. The main effect is that by setting feed ports at different depths and positions inside the pulp, the pulp at different depths and positions is sucked into the connecting pipe through the exhaust device for measurement. The pulp can be sucked into the device more stably through the exhaust device, avoiding the influence on the pulp stability when using a spiral suction device, making the pulp maintain a good flow state near the sampling point, reducing the stratification phenomenon, further measuring the pulp entering the inside of the connecting pipe separately, completing the concentration measurement of different depths and positions inside the pulp. Further, the measured pulp in the connecting pipe is extracted into the sampling pipe through the extraction device arranged inside the sampling pipe. The pulp enters the sampling pipe through the spiral pipe structure arranged at the end of the connecting pipe and collides and merges with each other automatically. Cooperating with the exhaust device arranged on the sampling pipe, the pulp is further extracted into the sampling pipe for fusion. Measuring the pulp in the sampling pipe can obtain the preliminary average concentration of the pulp. By comparing the average concentration with the individual concentrations at each position, the concentration state comparison of each position of the pulp can be obtained, providing data support for subsequent processing. Further, the pulp can be extracted through the pulp outlet arranged at the bottom of the device for further mixing and stirring, and more accurate concentration measurement can be carried out to measure the concentration that can more accurately reflect the average concentration of each position of the pulp.

[0004] To achieve the above object, the utility model is realized through the following technical solutions:

[0005] A slurry concentration sampling device includes a sampling pipe. A number of spiral pipes are fixedly arranged at the rear of the sampling pipe and are communicated with it. A connecting pipe one is fixedly arranged at the rear of the spiral pipe and is communicated with it. A flange is fixedly arranged at the rear of the connecting pipe one and is communicated with it. A connecting pipe two is arranged at the rear of the flange. A elbow pipe is arranged at the rear of the connecting pipe two and is communicated with it. A feed inlet is fixedly arranged at the rear of the elbow pipe.

[0006] Furthermore, an extension rod is fixedly arranged on the upper part of the sampling pipe. An exhaust valve is fixedly arranged at the rear of the extension rod. A number of communicating pipes are fixedly arranged at the bottom of the exhaust valve and are communicated with it.

[0007] Furthermore, an exhaust pipe is fixedly arranged and connected between the rear part of the sampling pipe and the upper part of the connecting pipe one. A liquid sensor is fixedly arranged on one side of the exhaust pipe. An exhaust connecting pipe is arranged between each exhaust pipe and each communicating pipe to connect the two.

[0008] Furthermore, an electric push rod is fixedly arranged at the center of the front part of the sampling pipe. The telescopic end of the electric push rod penetrates through the sampling pipe. A suction disc is fixedly arranged at the end of the telescopic end of the electric push rod. A rubber ring is fixedly arranged around the suction disc.

[0009] Furthermore, a concentration detector one is fixedly arranged and communicated with the bottom of the sampling pipe. A concentration detector two is fixedly arranged and communicated with the lower part of each connecting pipe one.

[0010] Furthermore, a drain valve is fixedly arranged and communicated with the bottom of the sampling pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. By arranging feed inlets at different depths and positions inside the slurry, the slurry at different depths and positions is sucked into the connecting pipe through the exhaust device for measurement. Sucking the slurry through the exhaust device can make the slurry be sucked into the device more stably, avoiding the influence on the stability of the slurry when using a spiral suction device. Further, the slurry entering the connecting pipe is measured separately to complete the measurement of the concentration of the slurry at different depths and positions inside the slurry.

[0013] 2. The extraction device arranged inside the sampling tube extracts the measured pulp in the connecting pipe into the sampling tube. The spiral tube structure arranged at the end of the connecting pipe enables the pulp to collide and blend with each other during the process of entering the sampling tube. The exhaust device arranged on the sampling tube further extracts the pulp into the sampling tube for blending. By measuring the mixed pulp in the sampling tube, the preliminary average concentration of the pulp can be obtained. By comparing the average concentration with the individual concentrations at each position, the comparative concentration state of the pulp can be obtained, providing data support for subsequent processing. Further, by extracting the internal pulp through the drain valve and the pulp extracted from different positions, further mixing and stirring of the pulp can be carried out to measure the concentration that can more accurately reflect the average concentration at each position of the pulp.

[0014] 3. By setting and removing the longer connecting rod, the device can be inserted deeper for sampling and measurement, facilitating the use by personnel. Brief Description of the Drawings

[0020] Embodiment: A device for sampling the concentration of pulp

[0021] As Figures 1-3 shown, a device for sampling the concentration of pulp, its specific structure includes:

[0022] A slurry concentration sampling device, including a sampling pipe 1. A number of spiral pipes 2 are fixedly arranged at the rear of the sampling pipe 1 and communicated therewith. A connecting pipe 1 3 is fixedly arranged at the rear of the spiral pipe 2 and communicated therewith. A flange 4 is fixedly arranged at the rear of the connecting pipe 1 3 and communicated therewith. A connecting pipe 2 5 is arranged at the rear of the flange 4. A bent pipe 6 is arranged at the rear of the connecting pipe 2 5 and communicated therewith. A feed inlet 7 is fixedly arranged at the rear of the bent pipe 6. By setting the connecting pipe 2 5 and the bent pipe 6 with different lengths and shapes, the feed inlet 7 can be located at different positions in the slurry for sampling and measurement.

[0023] An extension rod 8 is fixedly arranged at the upper part of the sampling pipe 1, which is used to enable the device to extend into slurries of different depths for measurement, facilitating the user to use. An exhaust valve 9 is fixedly arranged at the rear of the extension rod 8. A number of communicating pipes 10 are fixedly arranged at the bottom of the exhaust valve 9 and communicated therewith, which are used to discharge the air in the device and then extract the slurry into the device. By the air extraction method, the stability of the slurry is maintained, and the influence on the slurry caused by using a turbine extraction device to extract the slurry is avoided.

[0024] An exhaust pipe 11 is fixedly arranged and connected between the rear part of the sampling pipe 1 and the upper part of the connecting pipe 1 3. A liquid sensor 12 is fixedly arranged on one side of the exhaust pipe 11, which is used to stop the corresponding exhaust valve 9 from exhausting when detecting liquid when the slurry enters the exhaust pipe 11 after the air extraction is completed, preventing the slurry from entering the exhaust valve 9. An exhaust connection pipe 13 is arranged between each exhaust pipe 11 and each communicating pipe 10 to connect the two.

[0025] An electric push rod 14 is fixedly arranged at the center of the front part of the sampling pipe 1. The telescopic end of the electric push rod 14 penetrates through the sampling pipe 1. An extraction disc 15 is fixedly arranged at the end of the telescopic end of the electric push rod 14. A rubber ring 16 is fixedly arranged around the extraction disc 15. The extraction disc 15 is attached to the inner wall of the sampling pipe 1 through the rubber ring 16, and the extraction disc 15 moves in the sampling pipe 1 through the telescopic movement of the electric push rod 14, so that the slurry is drawn into the sampling pipe 1 from the spiral pipe 2. The slurry enters the sampling pipe 1 at a certain angle through the spiral pipe 2, enabling the slurry to blend with each other, and then the slurry is blended into an average concentration, and the sedimentation of the internal components of the slurry can be prevented, and then the average concentration of the slurry can be measured.

[0026] A concentration detector 1 17 is fixedly arranged and communicated at the bottom of the sampling pipe 1. A concentration detector 2 18 is fixedly arranged and communicated at the lower part of each connecting pipe 1 3. The concentration detector 1 17 is used to measure the slurry concentration of the slurry blended at different positions in the sampling pipe 1, and the concentration detector 2 18 is used to measure the separate slurry concentration at different positions inside the slurry.

[0027] A drain valve 19 is fixedly installed at the bottom of the sampling pipe 1 and is communicated therewith, for discharging the pulp in the device after measurement for further mixing measurement.

[0028] Working principle:

[0029] When this device is in use, the second connecting pipe 5 with different lengths and the elbow pipe 6 with different shapes are selected according to needs, so that each feeding port 7 can be located at different positions inside the pulp for sampling measurement. Further, the device is placed into the pulp through the extension rod 8, and the extension rod 8 is fixed to fix the device. The air pressure inside the connecting pipe and the suction disc 15 are used to fit the communication port part between the connecting pipe and the sampling pipe 1 to prevent the pulp from entering the connecting pipe in advance. The exhaust pipe 11 provided at the upper part of the first connecting pipe 3 is connected to the exhaust valve 9, and the air in the connecting pipe is discharged through the exhaust valve 9 so that the pulp enters the connecting pipe through the feeding port 7. When too much pulp is extracted and the pulp contacts the liquid sensor 12, the corresponding exhaust valve 9 is controlled to stop exhausting to prevent the pulp from entering the exhaust valve 9. Further, the concentration detector II 18 is used to detect the pulp concentration in the first connecting pipe 3 for measuring the pulp concentration at different positions inside the pulp. Further, the electric push rod 14 is contracted to move the suction disc 15 and the rubber ring 16 provided on the outer periphery in the sampling pipe 1, and the pulp inside the spiral pipe 2 is extracted. The pulp enters the sampling pipe 1 at a certain angle through the spiral pipe 2 for mutual fusion, and is communicated with the exhaust pipe 11 communicated with the sampling pipe 1 and the exhaust valve 9. The air in the sampling pipe 1 is discharged through the exhaust valve 9 to help the sampling pipe 1 extract the pulp. Further, the concentration detector I 17 is used to detect the pulp concentration in the sampling pipe 1 to detect the preliminary average concentration after the pulp at each position inside each pulp is fused. After the detection is completed, the pulp is extruded through the suction disc 15 and the air is reversely inflated through the exhaust pipe 11 so that the pulp is discharged from the feeding port 7 and the drain valve 19 for further full mixing detection to perform a more accurate concentration measurement that can reflect the average concentration at each position of the pulp. This device can measure the pulp concentration at different positions inside the pulp, and the pulp can stably enter the device through the pneumatic device, and the preliminary average concentration can be measured after the pulp at each part is fused through the pneumatic device. The preliminary average concentration data can be quickly obtained and compared with the pulp concentration at each position respectively to obtain the comparison concentration situation at different positions of the pulp concentration. The device can be further taken out of the pulp to perform further full mixing detection on the pulp fused inside and the pulp extracted from each position to perform a more accurate concentration measurement that can reflect the average concentration at each position of the pulp. This device has a simple structure and is convenient to use, and is suitable for popularization and use.
