[0002] The main part of the slurry sampling equipment is a short tube connected in series to the slurry conveying pipeline, and a sampling tube inserted radially along the short tube. The sampling tube is directly driven by a cylinder or a motor drives the turntable swing arm to drive the sampling tube to reciprocate and sample from the slurry flowing through the short tube.

[0003] The two driving forms of existing slurry sampling equipment are suitable for different working environments. For example, cylinder-driven sampling is suitable for use in environments with compressed air sources, while motor-driven sampling is suitable for use in factories with convenient access to 220V or 380V power supplies. However, the above two driving forms are still difficult to cover all slurry production scenarios. When the sampling points through which the slurry conveying pipeline passes are difficult to provide industrial electricity or compressed gas energy, the applicability of the existing slurry sampling equipment will become poor. Therefore, the present invention proposes a gold slurry sampling device for gold mines that uses a low-voltage DC power supply and utilizes the slurry conveying pressure to achieve passive slurry sampling.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] Example 1, reference Figure 1 to Figure 4 This embodiment provides a gold slurry sampling device for gold mines, which uses the pipeline pressure of the slurry as the sampling power source, and realizes the use of a more easily available and safe low-voltage DC power supply to drive the sampling device to complete the sampling. Figure 1 As shown, it includes a cross-shaped four-way pipe 100, the two ends of the four-way pipe 100 located on one axis are respectively a slurry inlet 101 and a slurry outlet 102, and the two ends of the four-way pipe 100 located on another axis are respectively sampling ports 103. Figure 2As shown, the two sampling ports 103 are both sealed and fixedly provided with cover plates 104, and the two cover plates 104 are both provided with discharge ports 105 on the sides away from each other, and the discharge ports 105 are both connected to electromagnetic valves 106; pistons 107 are both sealed and slidable in the two sampling ports 103, and short tubes 108 are inserted between adjacent cover plates 104 and pistons 107, and electromagnetic push rods 109 are fixedly installed on the ends of the two short tubes 108 away from each other, as shown in FIG. Figure 3 As shown, two short tubes 108 are located on the side away from the two pistons 107 and are provided with circular holes 110. The circular holes 110 are arranged in a ring array about the short tubes 108, and sliders 111 are sealed and slidably sleeved at the openings in the short tubes 108. The slider 111 is coaxially connected to the adjacent electromagnetic push rod 109. A sampling tube 112 is also sealed and connected between the two short tubes 108, and a groove 113 is provided on the side wall of the sampling tube 112.

[0025] Specifically, Figure 2 As shown, the cover plate 104 is sealed and fixedly connected with a proximity switch 118, and the proximity switch 118 is arranged at the top edge of the corresponding piston 107. The discharge port 105 of the cover plate 104 is arranged at the bottom of the short tube 108, and the discharge port 105 is connected to the bent pipe 119, one end of the bent pipe 119 is downward and connected to the solenoid valve 106.

[0026] The present invention provides a slurry sampling device, and in particular provides a technology for realizing slurry sampling by utilizing the pressure of a slurry conveying pipe. Different from the existing motor-driven sampling device that requires an industrial power supply and the cylinder-driven sampling device that requires a compressed air source, the present invention can be powered by a small mobile low-voltage DC power supply, and thus can be installed and used at any position of the slurry conveying pipeline, with relatively few restrictions on use. The existing two sampling devices with different driving forces are limited in that they require a strong power supply and air source to be used, and therefore the installation and use positions are more restricted than those of the present invention.

[0027] The working principle of the sampling device of the present invention is that, firstly, the static pressure generated by the strong pump pressure on the piston 107 during slurry transportation is utilized; secondly, the pressure difference on both sides of the piston 107 is utilized to drive the piston 107 to move; thirdly, the reciprocating action of slurry extraction and discharge is realized by controlling the pressure state of the two pistons 107;

[0028] The pressure that pushes the piston 107 comes from the static pressure of the fluid in the pipeline on the pipe wall. The static pressure has nothing to do with the area of ​​the piston 107 and is not affected by the area of ​​the piston 107. However, under the same static pressure, the total pressure on the piston 107 depends on the area of ​​the piston 107. Therefore, Figure 2As shown, a pair of pistons 107 with larger end areas are used in the device to obtain sufficient driving force to overcome the resistance to its movement. The distance between the two pistons 107 is relatively fixed. The static pressure on the side of the piston 107 facing the inside of the pipeline is normal pressure and is not adjusted, while the side of the piston 107 facing away from the inside of the pipeline can control the opening and closing of the static pressure by whether it is connected to the inside of the pipeline. Therefore, the pressure difference on both sides of the piston 107 is controllable. When the thrust generated by the pressure difference is greater than the resistance to the movement of the piston 107, the piston 107 can be moved. During the movement, the piston 107 away from the cover plate 104 increases the volume between it and the cover plate 104 to extract the slurry, while the piston 107 close to the cover plate 104 squeezes out the slurry as a sample. Repeated reciprocating movements can be used for continuous sampling.

[0029] The specific process is as follows: Figure 3 Taking the perspective as an example, the right solenoid valve 106 located on the right side of the four-way pipe 100 closes the right discharge port 105, and the right solenoid push rod 109 drives the slider 111 to open the circular hole 110, so that the slurry enters the back of the piston 107 through the sampling tube 112, the swing arm 114 and the circular hole 110 on the short tube 108, thereby balancing the pressure on both sides of the piston 107, and the left solenoid push rod 109 located on the left side of the four-way pipe 100 drives the slider 111 to close the circular hole 110, and the left solenoid valve 106 is opened, so that the slurry on the back of the left piston 107 is connected to the atmosphere with lower pressure, which makes the left piston 107 subject to a large pressure difference, which pushes the left piston 107 to move toward the left cover plate 104, squeezes the slurry through the left discharge port 105, and also drives the right piston 107 to move away from the right cover plate 104, thereby drawing more slurry into between the right piston 107 and the right cover plate 104, preparing for the next step of squeezing out the slurry sample.

[0030] During the process, the proximity switch 118 is used to identify whether the piston 107 has moved into position. Figure 2 Taking the perspective as an example, the left piston 107 moves to the left to discharge the slurry. When the piston 107 moves to the end point of the stroke, it will also trigger the proximity switch 118 on the left. The equipment uses the signal of the proximity switch 118 as the trigger condition to control the two electromagnetic push rods 109 to switch the telescopic state and the two electromagnetic valves 106 to switch the open and closed state, so that the piston 107 changes direction and moves to the right. The same is true when the right piston 107 moves to the right and triggers the proximity switch 118 on the right.

[0031] In summary, sampling is only required when the slurry is transported in the slurry pipeline. At the same time, there will be sufficient pipeline pressure in the slurry pipeline to provide the present invention with a driving force. The present invention only needs to use a portable mobile power supply with low-voltage direct current (for example, 24V direct current) to drive the solenoid valve 106 and the electromagnetic push rod 109 to work, adjust the pressure difference between the static pressure acting on the two pistons 107, and use the pressure difference to realize the reciprocating motion of the piston 107, so as to continuously output the slurry sample.

[0032] Example 2, the slurry sampling device of the present invention is also significantly different from the existing slurry sampling equipment in that the sampling tube of the existing slurry sampling equipment can only move in a straight line along the radial direction of the pipeline to extract slurry, and the cross-section of the pipeline is circular, so the sampling position distribution is not uniform enough.

[0033] like Figure 3 As shown, the short tube 108 is sealed and slidably plugged with the cover plate 104, one end of the short tube 108 is fixedly sleeved with the piston 107, and one end of the two short tubes 108 located between the two pistons 107 is rotatably and sealedly connected with a swing arm 114, and one end of the two swing arms 114 away from the short tube 108 is respectively sealed and rotatably connected with the two ends of the sampling tube 112, the swing arm 114 is hollow and connects the sampling tube 112 and the short tube 108, and the outer wall of the swing arm 114 is fixedly connected with a screw rod 116 in the direction away from the short tube 108, and the screw rod 116 is coaxial with the short tube 108, the screw rod 116 is threadedly connected with a nut 117, and the outer wall of the nut 117 is fixedly connected with the inner wall of the cross-way pipe 100, and the movement stroke of the piston 107 is equal to half the pitch of the screw rod 116; Figure 2 and Figure 4 As shown, the long side of the notch 113 on the sampling tube 112 is arranged parallel to the axial direction of the sampling tube 112, and the sampling tube 112 is located on the back side of the notch 113 and is fixedly connected with a spoiler 115, the spoiler 115 is arranged in a "Y" shape, and the end of one short side of the "Y" shape of the spoiler 115 is attached to the inner wall of the sampling tube 112 and fixedly sleeved, and the other short side of the "Y" shape of the spoiler 115 is arranged along the arc tangent direction of the outer wall of the sampling tube 112.

[0034] The sampling tube 112 of the present invention is horizontally placed inside the pipeline, making full use of the internal space of the four-way pipe 100. The swing arm 114 is used to enable the sampling tube 112 to swing up and down in the pipeline, so that the sampling range of the sampling tube 112 covers most of the area of ​​the pipeline flow cross-section, the sampling is more uniform, and the slurry sample information is more accurate. Specifically, the piston 107 is used to drive the screw rod 116 to move relative to the nut 117 and the four-way pipe 100 during the reciprocating motion, so that the screw rod 116 rotates relative to the nut 117 to drive the swing arm 114 and the sampling tube 112 to deflect, wherein the sampling tube 112 can freely rotate relative to the swing arm 114, and the slurry inlet slot 113 of the sampling tube 112 supports the spoiler 115 by the slurry flow to keep the slot 113 in the opposite direction of the slurry flow.

[0035] In summary, the sampling tube 112 of the present invention can sample different positions in the pipeline, and the sampling range is relatively large relative to the pipeline flow cross-section, and can output slurry samples with more accurate information.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
