Description

Technical Field

[0001] This utility model belongs to the technical field of mining equipment and relates to a pump-suction type automatic slurry sampling device. Background Technology

[0002] In mineral processing, to ensure ore processing quality and effective control of the production process, it is necessary to regularly sample and analyze the slurry. Analysis requires multiple samplings throughout the day to obtain an average sample. Due to the long flotation process, multiple sampling points are required. Currently, this is done manually using a sampling spoon inserted into the flotation machine's ear box / stirring tank. However, because of the high slurry flow rate and strong suction at the pipe inlet, personnel often lose their grip, causing the sampling spoon to fall into the slurry and leading to equipment malfunctions. Furthermore, traditional manual sampling methods are not only inefficient but also lack randomness and accuracy, easily influenced by operator subjectivity. While some existing sampling devices can improve sampling accuracy to some extent, they are complex in structure, cumbersome to operate, and expensive, increasing labor intensity and costs. In addition, existing slurry sampling devices have poor adaptability to different slurry depths and concentrations, failing to meet diverse sampling needs. Therefore, designing a simple and automated slurry sampling device is of great significance. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a pump-suction type automatic slurry sampling device, which solves the problems of low efficiency and difficulty in guaranteeing the randomness and accuracy of traditional manual sampling methods.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] An automatic slurry sampling device using a pump-suction mechanism includes a frame. A sampling pump housing is located at the top of the frame. A self-priming centrifugal pump is located inside the sampling pump housing. A slurry suction pipe is located at the bottom of the sampling pump housing, and a slurry discharge pipe is located on the side. The suction port of the self-priming centrifugal pump is connected to the suction pipe, and the discharge port is connected to the discharge pipe. The discharge pipe is U-shaped and includes a horizontal section, an inclined section, and a vertical section connected in sequence. The other end of the horizontal section of the discharge pipe is connected to the self-priming centrifugal pump. A sampling container is located below the other end of the vertical section of the discharge pipe. A liquid level sensor is located on the inner wall of the sampling container near the top.

[0006] Furthermore, the frame is inverted U-shaped, with frame bases at both ends.

[0007] This utility model also includes a control system, which includes a speed-regulating motor, a processing module, a timing module, and a display module. The processing module is connected to the speed-regulating motor, the sampling pump, the timing module, and the display module via signals, and the sampling pump and the speed-regulating motor are electrically connected.

[0008] The beneficial effects of this utility model are as follows:

[0009] This invention overcomes the shortcomings of existing slurry sampling devices, achieving efficient, accurate, and automatic slurry sample collection while reducing costs and manual operation. Furthermore, it is equipped with an automatic control system, where the processing module receives data from the level sensor and controls the speed of the sampling pump's speed-regulating motor according to a preset program. The automatic control system also includes a timed sampling module that automatically starts the sampling process at set time intervals, enabling unattended automatic sampling. Finally, it features a display module that displays the device's operating status and sampling parameters in real time, facilitating operator monitoring. Attached Figure Description

[0012] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0013] like Figure 1 As shown, a pump-suction type automatic slurry sampling device includes a frame 1, which is inverted U-shaped, with frame bases 8 at both ends.

[0014] The top of the frame 1 is equipped with a sampling pump housing 3, and the sampling pump 7 is installed inside the sampling pump housing 3. The sampling pump 7 is a self-priming centrifugal pump, which has good self-priming ability and can effectively avoid air binding. The bottom of the sampling pump housing 3 is equipped with a slurry suction pipe 2 and the side is equipped with a slurry discharge pipe 4. Specifically, the slurry suction pipe 2 is a stretchable, high-strength, corrosion-resistant and wear-resistant plastic hose, one end of which is connected to the sampling pump housing 3 and the other end extends into the slurry pool to draw up the slurry. The slurry discharge pipe 4 is made of hard plastic and has good corrosion resistance.

[0015] The suction port of the sampling pump 7 is connected to the suction pipe 2, and the discharge port is connected to the discharge pipe 4. The discharge pipe 4 is U-shaped and includes a horizontal section, an inclined section and a vertical section connected in sequence. The other end of the horizontal section of the discharge pipe 4 is connected to the sampling pump 7. The other end of the vertical section of the discharge pipe 4 is provided with a sampling container 5, which is a sealed stainless steel barrel. A liquid level sensor 6 is provided on the inner wall of the sampling container 5 near the top.

[0016] This utility model also includes a control system, which includes a speed-regulating motor, a processing module, a timing module, and a display module. The processing module is connected to the speed-regulating motor, the sampling pump 7, the timing module, and the display module via signals. The sampling pump 7 and the speed-regulating motor are electrically connected.

[0017] This invention enables precise adjustment of the motor speed through a control system, thereby adjusting the sampling rate of the sampling pump 7 to achieve accurate control of the slurry sampling flow rate. In addition, the speed-regulating motor and the control system are connected by a waterproof seal to ensure safe and stable operation in a humid slurry environment. Since the control system in this invention uses existing control equipment, its specific structure and working principle will not be described in detail.

[0018] The usage process of this utility model is as follows:

[0019] First, move the device to a suitable location near the slurry pool and adjust the frame base 8 to a horizontal state using the leveling device. Second, connect the power supply and check whether the connection between the slurry suction pipe 2 and the slurry discharge pipe 4 and the sampling pump 7 is secure, ensuring that all components are working properly.

[0020] When the set sampling time interval is reached, the processing module sends a start signal to the speed-regulating motor, and the sampling pump 7 starts working. The slurry is transported by the sampling pump 7 to the sampling container 5 through the slurry discharge pipe 4. When the liquid level sensor 6 detects that the slurry in the sampling container 5 has reached the preset liquid level, it sends a signal to the processing module, and the processing module controls the sampling pump 7 to stop working. When it is necessary to extract a slurry sample for analysis, the valve of the sampling port at the top of the sampling container 5 is opened, and the slurry sample is taken out using a suitable tool. After the sample extraction is completed, wait for the next sampling time interval to arrive, and repeat the above sampling process.
