Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of mineral processing auxiliary equipment, and specifically provides a slurry sampling device. Background Technology
[0002] Sampling is a crucial step in the production process of a mineral processing plant, playing a vital role in achieving its various technical and economic targets. Only through systematic inspection of the mineral processing process and the acquisition of various production data can the normality of the process be analyzed and the quality of the mineral processing work assessed. Therefore, all mineral processing plants should attach great importance to the sampling process to ensure the normal operation of their production technical indicators.
[0003] Therefore, when the flotation machine is operating normally, the foam product is scraped into the foam tank by the scraper and concentrated in the foam pump pool. Product sampling is very important in this process.
[0004] Currently, most ore dressing plants use traditional sampling methods, employing self-made sampling pots for manual sampling. This involves designated personnel taking samples at specified times, with the sample size determined by practical experience. The main disadvantages of manual sampling are: high degree of human subjectivity, poor control over sampling intervals, and high labor intensity from repeated sampling. Utility Model Content
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a slurry sampling device, including a sampling vessel, a connector, a rigid sleeve, a pressure roller assembly and a hose. The lower end of the sampling vessel is a tapered constriction, and a first one-way valve is provided at the tapered constriction. The rigid sleeve is assembled below the tapered constriction through the connector. The upper end of the hose is connected to the first one-way valve, and the hose extends downward through the rigid sleeve. A second one-way valve is provided at the lower end of the hose.
[0006] The pressure roller assembly consists of a wheel frame and pressure rollers. Multiple pressure rollers are symmetrically mounted on the wheel frame, which is rotatably mounted on a rigid sleeve. During the rotation of the wheel frame, the pressure rollers squeeze the hose when they are closest to the inner wall of the rigid sleeve.
[0007] Furthermore, the wheel frame is triangular, and there are three pressure rollers, which are located at the three apex points of the wheel frame.
[0008] Furthermore, the lower half of the rigid sleeve is an arc-shaped support plate, and support frames are provided on both sides of the arc-shaped support plate, with the wheel frame rotatably mounted between the two support frames.
[0009] Furthermore, the pressure roller assembly also includes a motor, which is fixedly mounted on a rigid sleeve.
[0010] Furthermore, the pressure roller assembly also includes an independent power supply component, which is fixedly installed on a rigid sleeve and electrically connected to the motor via a circuit.
[0011] Furthermore, the sampling vessel is connected to an external displacement mechanism via a connecting mechanism.
[0012] The beneficial effects of using this utility model are:
[0013] This device can replace traditional manual sampling, reducing the labor intensity of staff and lowering the expenditure of human and material resources;
[0014] The device has a simple structure and operating principle, is not prone to abnormalities during operation, has good operational stability, and has low manufacturing costs.
[0015] This device can be adapted to intelligent systems, enabling precise management of sampling travel and sampling cycle, which is beneficial to industry progress. Attached Figure Description

[0030] The present invention will now be described in detail with reference to the accompanying drawings.
[0031] Reference Figures 1-3 A slurry sampling device includes a sampling vessel 1, a connector 2, a rigid sleeve 3, a pressure roller assembly 4, and a flexible hose 5. The lower end of the sampling vessel 1 is a tapered constriction, and a first one-way valve 101 is provided at the tapered constriction. The rigid sleeve 3 is assembled below the tapered constriction through the connector 2. The upper end of the flexible hose 5 is connected to the first one-way valve 101, and the flexible hose 5 extends downward through the rigid sleeve 3. A second one-way valve 501 is provided at the lower end of the flexible hose 5.
[0032] The pressure roller assembly 4 consists of a wheel frame 403 and pressure rollers 404. Multiple pressure rollers 404 are symmetrically mounted on the wheel frame 403. The wheel frame 403 is rotatably mounted on the rigid sleeve 3. During the rotation of the wheel frame 403, the pressure rollers 404 squeeze the hose 5 when they are closest to the inner wall of the rigid sleeve 3.
[0033] Both the first check valve 101 and the second check valve 501 are unidirectionally open to the upward direction.
[0034] During device operation, when the wheel frame 403 rotates to the state where the pressure wheel 404 squeezes the hose 5, the contents of the hose 5 are pushed upward into the sampling container 1 through the first one-way valve 101;
[0035] When the wheel frame 403 rotates to the state where the pressure wheel 404 is disengaged from the hose 5, the hose 5 recovers under the action of elasticity. During the recovery process, negative pressure is generated in the hose 5, the second one-way valve 501 opens, and the sample in the foam tank is sucked into the hose 5.
[0036] The wheel frame 403 rotates again to the state where the pressure roller 404 squeezes the hose 5, pressing the collected sample into the sampling container 1.
[0037] Specifically, the wheel frame 403 is triangular, and there are three pressure rollers 404, which are located at the tips of the three corners of the wheel frame 403.
[0038] Specifically, the lower half of the rigid sleeve 3 is an arc-shaped support plate 301, and support frames 302 are provided on both sides of the arc-shaped support plate 301. The wheel frame 403 is rotatably installed between the two support frames 302.
[0039] The pressure roller assembly 4 also includes a motor 401, which is fixedly mounted on the rigid sleeve 3.
[0040] Preferably, the motor 401 is fixedly mounted on the outside of the support frame 302.
[0041] The pressure roller assembly 4 also includes an independent power supply assembly 402, which is fixedly installed on the rigid sleeve 3 and is electrically connected to the motor 401 via a line.
[0042] Preferably, the independent power supply component 402 is fixedly installed on the outside of the support frame 302.
[0043] The sampling container 1 is connected to an external displacement mechanism via a connecting mechanism. Driven by the displacement mechanism, the sampling container 1 moves horizontally within the foam tank.
[0044] Specifically, the connecting mechanism adopts a mechanical boom 6, and the displacement mechanism adopts a railcar or a self-propelled chassis vehicle.
[0045] The sampling operation process is as follows:
[0046] 1. Adjust the connecting rod so that the center line of sampling vessel 1 is located 100mm below and 150mm in front of the overflow weir (the input end of the foam tank);
[0047] 2. Set the sampling stroke and sampling cycle according to the requirements. The displacement mechanism moves at fixed time and distance according to the set sampling stroke and sampling cycle to realize multi-point sampling throughout the flotation operation, making the collected samples more representative.
[0048] Specifically, the typical flotation operation cycle is 4-8 hours, so it is reasonable to set the sampling cycle to once every 0.5 hours.
[0049] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the concept of this utility model. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this utility model.
