Description

Technical Field

[0001] The utility model belongs to the technical field of ore pulp sampling in a mineral processing system, in particular to an electric propulsion type ore pulp sampling device. Background Art

[0002] In the mineral processing production process, product quality process control is particularly important, and it is necessary to continuously take samples for analysis to guide the adjustment of quality indicators of the production system. Generally, two methods are used: manual sampling or mechanical sampling. The sampling interval of manual sampling is long and the sampling techniques are different, resulting in inaccurate samples, reduced reliability, and inability to guide production in a timely manner, which also increases the labor intensity of employees. The mechanical sampler uses a fixed chute interceptor to intercept the slurry, which is fed into the receiving box through the feeding pipe. The hydraulic push device pushes the sample knife to move through the feeding slurry flow. The slurry enters the guide pipe and enters the sample box through the guide plate. Once completed, the cycle is controlled by a manually adjusted time controller. During use, the following problems often occur: 1. The chute interceptor is installed in the middle of the chute, and the debris in the slurry often blocks the interceptor, and the slurry flow rate is fast, causing excessive wear and requiring frequent replacement. In addition, in order to prevent the pipeline from being blocked, it needs to be kept open for a long time, resulting in the loss of concentrate; 2. Due to the complex structure of the hydraulic push device, oil leakage, insufficient oil pressure and other faults often occur; 3. Sampling is often not timely, samples overflow, pollute the environment, and waste samples appear. Therefore, it is particularly important to develop and apply uniform and accurate automatic sampling equipment. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0016] The specific implementation of the present utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1 As shown, the electric propulsion type slurry sampling device of the utility model is characterized by comprising a chute interceptor arranged outside the factory building, a material receiving sampler connected to the chute interceptor through a hose 1-4,

[0018] The chute interceptor comprises a chute 1-5, a cover plate 1-6 arranged above the chute 1-5, an intercepting device 1-3 arranged at the bottom of the chute 1-5, and a cleaning device arranged on the cover plate 1-6. The intercepting device 1-3 is connected to the hose 1-4.

[0019] The material receiving sampler includes a material receiving box 2-5, a material guide trough 2-4 arranged in the material receiving box 2-5, a sample knife 2-3 arranged above the material guide trough 2-4, an extension rod 2-8 connected to the sample knife 2-3, an electric push rod II 2-9 driving the extension rod 2-8, a PLC control system 2-12 connected to the electric push rod II 2-9, a feeding pipe 2-1 arranged above the sample knife 2-3, a sampling box 2-6 arranged below the material guide trough 2-4, a weighing sensor 2-7 arranged below the sampling box 2-6, and the rubber hose 1-4 is connected to the feeding pipe 2-1.

[0020] The cleaning device comprises an arc-shaped scraper 1-2 and an electric push rod Ⅰ1-1 connected to the arc-shaped scraper 1-2.

[0021] One end of the extension rod 2-8 is connected to the electric push rod II 2-9, and the other end is connected to the connecting rod 2-2 arranged on the side wall of the material receiving box 2-5.

[0022] The material receiving box 2-5 is also provided with a flushing device, which includes a flushing water pipe 2-11 and a flushing solenoid valve 2-10.

[0023] The PLC control system 2-12 is connected to a proximity switch 2-14, which is arranged beside the sampling box 2-6. The PLC control system 2-12 is provided with a touch screen interface 2-13.

[0024] The electric push rod II 2-9 is provided with a protective sealing box on the outside.

[0025] Specific installation method:

[0026] 1. To make the chute interceptor, use a seamless steel pipe with a 200mm-300mm long external thread on one end and a 4mm×300mm axial gap on the other end; install the chute slurry interceptor at the bottom of the chute 1-5 and install the cleaning device on the cover plate 1-6. Figure 1 In order to prevent the interceptor gap from being blocked, a cleaning device (composed of an electric push rod 1-1, an arc scraper 1-2, etc.) is provided. Each time interception is performed, the arc scraper 1-2 is lifted, and the slurry flowing in the flow channel enters the feed pipe along the interceptor gap and flows into the interception box. After one cycle is completed, the arc scraper 1-2 is dropped, and the interception device is closed at the same time to stop the interception box from feeding ore, so as to achieve uniform interception and reduce the loss of concentrate.

[0027] 2. Make a material receiving box 2-5, install a material guide trough 2-4, a ore feeding pipe 2-1, a discharge pipe, and a flushing device (composed of a flushing water pipe 2-11 and a flushing solenoid valve 2-10) in the box;

[0028] 3. Make a protective sealing box for the electric push rod, install the electric push rod II 2-9 inside it to prevent the slurry from corroding the electric push rod II 2-9, and install the corrosion-resistant extension rod 2-8 on the electric push rod II 2-9 to prevent corrosion damage. Install it on one side of the receiving box 2-5;

[0029] 4. Install the sampling knife 2-3 on the electric push rod extension rod 2-8, adjust the angle, and connect the corrosion-resistant extension rod 2-8 with the connecting rod 2-2 to prevent shaking during movement, ensure the smooth operation of the sampling knife 2-3, and install an O-type seal in the tube at one end of the corrosion-resistant extension rod 2-8 to prevent the slurry from entering;

[0030] 5. Set up the PLC control system 2-12, write the PLC program, and set the interval time, weight setting, sampling frequency and other windows on the touch screen interface 2-13. The interval time and sample weight can be adjusted according to the type of material and actual on-site needs to intercept samples, so as to achieve uniform sampling according to time and weight, and improve sample reliability and operability;

[0031] 6. During operation, the electric push rod II 2-9 moves, extends and retracts according to the set interval time. When extending and retracting, the electric push rod extension rod 2-8 drives the sample knife 2-3 to evenly intercept the slurry through the ore feeding pipe 2-1. The slurry enters the guide pipe through the gap of the sampling knife 2-3. The slurry sample flows along the guide pipe into the guide trough 2-4 and enters the sampling box 2-6. The sampling process is completed. The unintercepted slurry enters the accident pool through the discharge pipe.

[0032] 7. According to the sampling volume, set the time interval, and automatically stop when the number of cycles is reached. Through the weighing sensor 2-7, it will also automatically stop when the weight is reached;

[0033] 8. After replacing the sampling box 2-6, the reset button (proximity switch 2-14) is automatically triggered to carry out the next cycle sampling process, thereby realizing automatic time-averaged sampling;

[0034] The equipment has the advantages of simple structure, easy operation, convenient maintenance, labor saving and accurate sample cutting.

[0035] It effectively solves the problems of inaccurate sample quality produced by manual sampling, complex hydraulic structure of conventional mechanical automatic samplers, difficult maintenance, and high failure rate.
