Description

Technical Field

[0001] This utility model relates to the technical field of mineral processing reagent processing equipment, and more specifically, to an atmospheric pressure sampling device for a high-pressure autoclave used in the preparation of mineral processing reagents. Background Technology

[0002] Mineral processing reagents mainly refer to collectors, frothers, inhibitors, flocculants, modifiers, as well as extractants, matrix improvers, and diluents used in hydrometallurgy. They involve hundreds of inorganic or organic compounds and play a crucial role in the mining process. They can penetrate deep into the ore and accurately identify the effective minerals in the ore by adjusting the chemical reaction of the slurry, thus laying a solid foundation for the smelting and processing of the mineral industry.

[0003] In the existing technology, when processing mineral processing reagents, it is necessary to sample and test them in order to ensure product quality. During sampling, pumps are generally used for extraction. After extraction, there will be residues of mineral processing reagents in the pump body, which is not easy to clean. As a result, the next sampling is prone to confusion, which affects product quality.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by designing an atmospheric pressure sampling device for preparing mineral processing reagents in a high-pressure autoclave.

[0006] The technical solution of this utility model to achieve the above objectives is a high-pressure autoclave atmospheric pressure sampling device for preparing mineral processing reagents, comprising an autoclave body, a plurality of sampling valves installed on the outside of the autoclave body, a sampling tube installed at the outlet end of the sampling valves, a sampling mechanism installed on the autoclave body, and a holding mechanism installed on the autoclave body.

[0007] The sampling mechanism includes a sampling box installed on one side of the sampling tube. The sampling box is installed on the autoclave body via a connecting rod. A movable piston is provided inside the sampling box. A drive frame is installed on the autoclave body. The drive frame can drive the movable piston to move.

[0008] The holding mechanism includes a drain valve installed on one side of the lower end of the sampling tube. A holding box is placed on the ground below the autoclave body. Multiple partitions are installed inside the holding box, which divides the interior of the holding box into multiple holding spaces. A drain pipe is installed at the lower end of the drain valve, and the lower end of the drain pipe extends into the holding space.

[0009] Furthermore, the drain valve is a rotary valve, and a rotary gear is installed on the rotating end of the drain valve. When the drive frame pushes the moving piston, it can cause the rotary gear to rotate and open and close the drain valve.

[0010] Furthermore, the drive frame includes a movable plate located on one side of the autoclave body. The movable plate has guide holes at both ends, and guide rods are installed in the guide holes. One end of the guide rod is connected to the autoclave body. The movable plate is connected to the autoclave body through multiple electric telescopic rods. Baffles are installed on both sides inside the sampling box. The baffles can limit the movement of the piston. Multiple push rods are installed on the movable plate. The push rods can push the piston. Multiple moving racks are connected to the movable plate. The moving racks mesh with rotating gears. When the drain valve is opened, the push rods can contact the piston.

[0011] Furthermore, a limiting slide is installed at the lower end of the sampling box, the moving rack is placed in the limiting slide, a limiting plate is installed at the upper end of the moving rack, and multiple L-shaped intercepting plates are installed on the moving plate. The L-shaped intercepting plates can limit the limiting plate, and the moving rack and the autoclave body are connected by a telescopic spring.

[0012] Furthermore, a cleaning valve is installed at one end of the sampling tube, and a water inlet pipe is connected to the inlet end of the cleaning valve. The water inlet pipe is connected to a water source. The cleaning valve can be opened and closed manually. The drain pipe is a flexible water pipe and is detachably connected to the container.

[0013] The beneficial effects of this utility model are as follows: When sampling, the sampling valve is opened first. Under the pressure of the autoclave itself, the mineral processing reagent can enter the sampling box through the sampling valve and sampling pipe for sampling. Multiple sampling points can be performed according to the number of sampling valves, sampling pipes, and sampling boxes. After sampling is completed, the sampling valve is closed. The moving piston can be driven by the drive frame to move, so that the mineral processing reagent can enter the holding tank through the drain valve and drain pipe. This facilitates sampling. Furthermore, during sampling, there is no need to let the mineral processing reagent pass through the pump body, making it easier to clean the sampling valve, sampling pipe, and sampling box.

[0014] By shortening the electric telescopic rod, the moving plate and push rod can be moved, which makes it easier to push multiple moving pistons at the same time. Before the moving pistons move, the drain valve can also be opened through gear transmission. Attached Figure Description

[0022] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] This utility model provides, for example Figure 1-5The apparatus shown is an atmospheric pressure sampling device for preparing mineral processing reagents using a high-pressure autoclave. It includes an autoclave body 1, multiple sampling valves 2 mounted on the outside of the autoclave body 1, sampling tubes 3 mounted at the outlet of each sampling valve 2, a sampling mechanism mounted on the autoclave body 1, and a holding mechanism mounted on the autoclave body 1. The sampling mechanism includes a sampling box 4 mounted on one side of the sampling tube 3, which is mounted on the autoclave body 1 via a connecting rod 5. A movable piston 6 is installed inside the sampling box 4, and a drive frame 7 is mounted on the autoclave body 1, which can move the movable piston 6. The holding mechanism includes a drain valve 8 mounted on one side of the lower end of the sampling tube 3, a holding box 9 placed on the ground below the autoclave body 1, multiple partitions installed inside the holding box 9, which divide the interior of the holding box 9 into multiple holding spaces, and a drain pipe 10 mounted at the lower end of the drain valve 8, with the lower end of the drain pipe 10 extending into the holding space.

[0024] The sampling process of this device for mineral processing reagents is as follows: Under normal conditions, sampling valve 2 is closed, and the mineral processing reagents are processed inside the autoclave body 1. When sampling is required, sampling valve 2 is opened, and under the pressure of the autoclave body 1 itself, the mineral processing reagents are forced through sampling valve 2 and sampling pipe 3 into sampling box 4. The moving piston 6 is pushed to one side, allowing the mineral processing reagents to enter sampling box 4. Then, sampling valve 2 is closed, allowing for simultaneous multi-point sampling. After sampling is completed, drain valve 8 is opened, and the moving piston 6 is returned to its original position via drive frame 7, allowing the mineral processing reagents to enter the holding box 9 through drain valve 8 and drain pipe 10, thus completing the sampling.

[0025] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The drain valve 8 is a rotary valve. A rotary gear 11 is installed on the rotating end of the drain valve 8. When the drive frame 7 pushes the moving piston 6, it can make the rotary gear 11 rotate and open and close the drain valve 8.

[0026] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The drive frame 7 includes a movable plate 12 located on one side of the autoclave body 1. The movable plate 12 has guide holes 13 at both ends, and guide rods 14 are provided in the guide holes 13. One end of the guide rods 14 is connected to the autoclave body 1. The movable plate 12 is connected to the autoclave body 1 through multiple electric telescopic rods 15. Baffles 16 are installed on both sides inside the sampling box 4. The baffles 16 can limit the movement of the piston 6. Multiple push rods 17 are installed on the movable plate 12. The push rods 17 can push the movement of the piston 6. Multiple moving racks 18 are connected to the movable plate 12. The moving racks 18 mesh with the rotating gear 11. After the drain valve 8 is opened, the push rods 17 can contact the movement of the piston 6.

[0027] The process of the drive frame 7 driving the moving piston 6 is as follows: Under normal conditions, the electric telescopic rod 15 is in its longest extended state, and the push rod 17 is not in contact with the moving piston 6. When the electric telescopic rod 15 is activated to shorten, the electric telescopic rod 15 can drive the moving plate 12 to move closer to the autoclave body 1. The guide rod 14 and the guide hole 13 can ensure the moving direction of the moving plate 12. When the moving plate 12 moves, the moving rack 18 can move first. Through the meshing of the moving rack 18 with the rotating gear 11, the rotating gear 11 can rotate and open the drain valve 8. After the drain valve 8 is opened, the push rod 17 can contact the moving piston 6. When the moving plate 12 continues to move, the moving piston 6 can be pushed by the push rod 17.

[0028] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Instruction manual attached Figure 4 Included with instruction manual Figure 5 The sampling box 4 is equipped with a limiting slide 19 at the lower end. The moving rack 18 is placed in the limiting slide 19. The moving rack 18 is equipped with a limiting plate 20 at the upper end. Multiple L-shaped intercepting plates 21 are installed on the moving plate 12. The L-shaped intercepting plates 21 can limit the limiting plate 20. The moving rack 18 and the high pressure vessel body 1 are connected by a telescopic spring 22.

[0029] The movement of the moving rack 18 is as follows: Under normal conditions, the telescopic spring 22 is in a stretched state, and the L-shaped interceptor plate 21 limits the limit plate 20, preventing the moving rack 18 from moving. After the moving plate 12 moves, under the tension of the telescopic spring 22, the moving rack 18 can move towards the high pressure vessel body 1. The limit slide 19 can ensure the direction of movement of the moving rack 18. After the moving rack 18 moves, the rotating gear 11 can rotate, and the drain valve 8 can be opened. When it is necessary to close the drain valve 8, the moving plate 12 moves away from the high pressure vessel body 1, and drives the L-shaped interceptor plate 21 to move. The L-shaped interceptor plate 21 can pull the limit plate 20 and the moving rack 18 back to their original positions. The moving rack 18 can make the rotating gear 11 rotate and close the drain valve 8.

[0030] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2A cleaning valve 23 is installed at one end of the sampling tube 3. The inlet end of the cleaning valve 23 is connected to a water inlet pipe 24, which is connected to a water source. The cleaning valve 23 can be opened and closed manually. The drain pipe 10 is a flexible water pipe, which is detachably connected to the container 9. When performing simple cleaning of this device, the cleaning valve 23 is opened, and cleaning agent is added to the sampling tube 3 and the sampling box 4 through the water inlet pipe 23. Then, the container 9 is disconnected from the drain pipe 10, and a wastewater tank is placed on the ground. The drain valve 8 is opened to drain the wastewater into the wastewater tank for simple cleaning. When a complete cleaning of this device is required after multiple uses, the moving piston 6 can be removed for cleaning.
