Description

Technical Field

[0001] This utility model relates to the field of sampler technology, and in particular to an adjustable pneumatic slurry pipeline sampler. Background Technology

[0002] In the industrial mineral processing production process, the function of the pneumatic slurry pipeline sampler is to extract a small amount of material sample from the slurry pipeline in order to analyze whether the various indicators of mineral processing meet the process requirements.

[0003] A search revealed Chinese utility model patent CN219810682U, which discloses "An Adjustable Pneumatic Slurry Pipeline Sampler." This sampler, utilizing a support base, support sleeve, electric telescopic rod, lifting plate, water-stop sleeve, sampling tube, and sampling port, can automatically sample the slurry by moving the sampling tube and sampling port up and down using the electric telescopic rod, allowing them to extend into the slurry pipeline. This device is simple in structure, easy to operate, and highly practical, making it economical and worthy of promotion.

[0004] However, the aforementioned existing technologies have certain drawbacks. After sampling, slurry remains on the inner wall of the sampling tube. However, due to the lack of a structure for recovering this slurry, it cannot be effectively collected. This not only wastes the slurry but may also affect the accuracy of subsequent sampling due to the slurry adhering to the inner wall of the sampling tube. It also increases the workload of maintaining the sampling tube and makes it impossible to achieve complete recovery and convenient collection of the slurry. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable pneumatic slurry pipeline sampler to solve the technical problems of inconvenient use and ineffective collection of residual slurry in existing samplers.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable pneumatic slurry pipeline sampler includes a pipeline body with a circular pipe extending through its side wall. A sampling cylinder is slidably installed inside the circular pipe and is controlled by a servo-driven cylinder. A negative pressure slurry collection mechanism is connected to the end of the sampling cylinder. The negative pressure slurry collection mechanism includes a piston cylinder, a piston rod, a handle, a one-way valve, and a central through-hole box. The piston cylinder is connected to the sampling cylinder. One end of the piston rod is slidably installed inside the piston cylinder, and the other end of the rod extends outside the piston cylinder. The handle is fixedly installed at the end of the piston rod. The one-way valve is located inside the piston rod at the connection point with the sampling cylinder. The central through-hole box is fixedly installed on the circumferential surface of the sampling cylinder and communicates with the sampling cylinder.

[0008] Preferably, the end of the material receiving cylinder that extends into the pipe body has a slurry inlet.

[0009] Preferably, the feed cylinder is equipped with an electric valve, which is located on the outside away from the slurry inlet.

[0010] Preferably, a geometric plate is fixedly installed on the circumferential surface of the pipe body, the geometric plate is sleeved on the circular pipe, a transmission plate is sleeved on the material picking cylinder, the cylinder servo is installed between the geometric plate and the transmission plate, and the output shaft of the cylinder servo is fixedly installed with the transmission plate.

[0011] Preferably, a plurality of reinforcing rods are installed between the piston cylinder and the transmission plate, and a fixing ring is sleeved on the piston cylinder, with the plurality of reinforcing rods fixedly connected to the fixing ring.

[0012] Preferably, a cover plate is threadedly fixed to the lower end of the central box.

[0013] The adjustable pneumatic slurry pipeline sampler provided by this utility model features a negative pressure slurry collection structure. After sampling, pulling the piston rod generates negative pressure, causing residual slurry on the inner wall of the sampling cylinder to enter the central box under negative pressure. The slurry can then be collected by removing the cover plate, thus achieving complete and convenient recovery of residual slurry and reducing the maintenance frequency of the sampling cylinder. Furthermore, an electric valve ensures a relative seal between the slurry inlet and the sampling cylinder, facilitating the use of the negative pressure slurry collection structure. The piston cylinder is fixed to the transmission plate by a reinforcing rod, enhancing its installation stability and preventing structural wobbling during piston rod operation, thereby ensuring stable and reliable negative pressure generation.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1 - Figure 4 As shown, this utility model provides an adjustable pneumatic slurry pipeline sampler, including a pipeline body 10, a circular pipe 11 connected through the side wall of the pipeline body 10, a sampling cylinder 13 sealed and slidably installed inside the circular pipe 11, the sampling cylinder 13 being driven and controlled by a cylinder servo 23 to slide inside the circular pipe 11, and a negative pressure slurry collection mechanism connected to the end of the sampling cylinder 13; the negative pressure slurry collection mechanism includes a piston cylinder 14, a piston rod 15, a handle 16, a one-way valve 17 and a central passage box 18, the piston cylinder 14 being connected to the sampling cylinder 13, one end of the piston rod 17 being slidably installed inside the piston cylinder 14 and the other end of the rod extending to the outside of the piston cylinder 14, the handle 16 being fixedly installed at the end of the piston rod 15, the one-way valve 17 being disposed inside the piston rod 15 at the connection with the sampling cylinder 13, and the central passage box 18 being fixedly installed on the circumferential surface of the sampling cylinder 13 and communicating with the sampling cylinder 13.

[0022] In order to facilitate the collection of slurry, a cover plate 19 is threadedly fixed to the lower end of the central box 18 in this embodiment. Slurry collection can be carried out by opening the cover plate. Of course, other methods can also be used, such as setting a valve on the central box.

[0023] This embodiment uses a negative pressure slurry collection structure to generate negative pressure when the piston rod is pulled after sampling. The residual slurry on the inner wall of the sampling cylinder enters the central box under the action of negative pressure, and the slurry can be collected through the central box. This achieves complete recovery and convenient collection of residual slurry, while also reducing the maintenance frequency of the sampling cylinder.

[0024] In a preferred embodiment, the sampling cylinder 13 has a slurry inlet 21 at the end extending into the pipe body 10 to facilitate the entry of slurry from the pipe body 1 into the sampling cylinder 13. A one-way valve 17 prevents slurry from entering the piston cylinder 14, thus restricting piston movement. Simultaneously, an electric valve 22 is provided on the sampling cylinder 13, located on the outer side away from the slurry inlet 21. After sampling, the operator closes the electric valve 22, creating a relative seal between the slurry inlet 21 and the sampling cylinder 13, thereby facilitating the use of the negative pressure slurry collection structure.

[0025] In a preferred embodiment, a geometric plate 12 is fixedly installed on the circumferential surface of the pipe body 10, and the geometric plate 12 is sleeved on the circular pipe 11. A transmission plate 24 is sleeved on the material handling cylinder 13. A cylinder servo 23 is installed between the geometric plate 12 and the transmission plate 24, and the output shaft of the cylinder servo 23 is fixedly installed on the transmission plate 24. Two cylinder servos 23 can be provided, respectively arranged on both sides of the geometric plate 12, symmetrically arranged to achieve pneumatic control balance. In this embodiment, the cylinder servos 23 can be controlled by an external PLC to complete the automated control of stroke adjustment.

[0026] The material collection cylinder 13 is installed in a sealed sliding manner between the pipe body 11 and the shaped plate 12. With the cylinder servo 23 symmetrically installed on the side wall of the shaped plate 12 and the transmission plate 24 on the material collection cylinder 13, when the operator starts the cylinder servo 23, the output shaft can drive the material collection cylinder 13 to move stably back and forth in the pipe body 11 through the transmission plate 24. The slurry can smoothly enter the material collection cylinder 13 through the slurry inlet 21 and flow into the central box 18, thereby achieving efficient sampling.

[0027] Several reinforcing rods 25 are installed between the piston cylinder 14 and the transmission plate 24. The piston cylinder 14 is fitted with a fixing ring 16, and the reinforcing rods 25 are fixedly connected to the fixing ring 16. By setting the reinforcing rods 25 and the fixing ring 26, the piston cylinder 14 can be effectively fixed, avoiding shaking during piston movement, thereby achieving stable and reliable negative pressure generation.

[0028] The working principle of the adjustable pneumatic slurry pipeline sampler in this embodiment is described in detail below:

[0029] The first step is that when the slurry passes through the pipe body 10, the operator can turn on the cylinder servo 23 (which needs to be connected to the air pump), so that the output shaft of the cylinder servo 23 drives the feeding cylinder 13 to move back and forth inside the round pipe 11 through the transmission plate 24. The slurry will then enter the feeding cylinder 13 through the slurry inlet 21 and flow into the central box 18 for storage.

[0030] The second step is to close the cylinder servo 23 and electric valve 22 after sampling, so that the slurry inlet 21 and the material collection cylinder 13 are in a relatively sealed state. Then, the piston rod 15 is pulled outward by the handle 16, so that the piston rod 15 generates negative pressure on the material collection cylinder 13. The slurry remaining on the inner wall of the material collection cylinder 13 will be transported to the piston cylinder 14 under the action of negative pressure, and then enter the central box 18. After that, the staff can remove the cover plate 19 to complete the slurry collection.

[0031] In summary, this application provides an adjustable pneumatic slurry pipeline sampler, effectively solving the technical problem of inconvenient use of existing samplers. By setting a negative pressure slurry collection structure, negative pressure is generated by pulling the piston rod after sampling. The residual slurry on the inner wall of the sampling cylinder enters the central box under the action of negative pressure, and the slurry can be collected by removing the cover plate. This achieves complete recovery and convenient collection of residual slurry, while also reducing the maintenance frequency of the sampling cylinder. At the same time, the electric valve can form a relative seal between the slurry inlet and the sampling cylinder, which is conducive to the use of the negative pressure slurry collection structure. Furthermore, the piston cylinder is fixed to the transmission plate by a reinforcing rod, which enhances the installation stability of the piston cylinder and makes the structure less prone to shaking when operating the piston rod, thereby achieving stable and reliable generation of negative pressure.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
