Description

Technical Field

[0001] This utility model relates to the field of chemical and metallurgical equipment, and in particular to a pipeline slurry sampling buffer device. Background Technology

[0002] In the alumina leaching process, it is necessary to periodically sample and analyze the slurry discharged from the flash evaporator. Currently, the sampling method is to open the sampling valve on the flash evaporator discharge pipe to allow the slurry to be discharged directly into the ditch. The sampling cup is placed next to the discharge pipe opening of the ditch to allow the slurry to flow into the sampling cup. During the valve opening process, the high-pressure and high-temperature slurry sprays out of the sampling discharge port and splashes everywhere, posing a safety hazard. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present invention aims to provide a pipeline slurry sampling buffer device. This device overcomes the defects of the prior art and can achieve the functions of pressure reduction and buffering during the slurry sampling process in the pipeline, so that the slurry flows slowly into the sampling cup without splashing, and the sampling process is safe, convenient and fast.

[0004] To solve the above problems, the technical solution of this utility model is as follows: A pipeline slurry sampling buffer device includes a barrel, a buffer cone, a discharge pipe, and a feed pipe, characterized in that: a conical buffer cone is provided in the lower part of the barrel, the top of the buffer cone faces upward, and a gap is left between the bottom edge of the buffer cone and the inner wall of the barrel; a feed pipe is provided in the lower part of the side wall of the barrel, and the feed pipe is inclined and faces the upper side of the buffer cone; a discharge pipe is provided at the bottom end of the barrel.

[0005] The axial direction of the buffer cone coincides with the axial direction of the barrel.

[0006] The top of the barrel is equipped with an exhaust pipe.

[0007] The bottom edge of the buffer cone is connected to the lower part of the inner wall of the barrel through several supports.

[0008] The lower end of the barrel is provided with a flared opening, and the feeding pipe is installed at the lower end of the flared opening.

[0009] The distance between the bottom edge of the buffer cone and the inner wall of the barrel is 25-35mm.

[0010] The beneficial effects of this utility model are as follows:

[0011] This application provides a pipeline slurry sampling buffer device that solves the problem of slurry splashing during the sampling process when the sampling valve is opened. Through the transition connection of the sampling buffer structure designed in this utility model, the pressure and speed of the slurry and the vapor-liquid separation are realized during the sampling process; the occurrence of various injury accidents caused by slurry splashing during the sampling process is eliminated; at the same time, this utility model has a simple structure, is easy to operate, safe and reliable, and is suitable for widespread application. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] The names and numbers of the parts in the diagram are as follows:

[0014] 1 is the barrel body, 2 is the buffer cone, 3 is the triangular support, 4 is the exhaust pipe, 5 is the discharge pipe, 6 is the discharge pipe, and 7 is the bell mouth. Detailed Implementation

[0015] The following description, in conjunction with the accompanying drawings, details the implementation methods and embodiments of this utility model and their working processes.

[0016] Referring to the accompanying drawings, a pipeline slurry sampling buffer device according to this embodiment includes a barrel 1, a buffer cone 2, a discharge pipe 5, and a feed pipe 6. The device is characterized in that: a conical buffer cone 2 is provided in the lower part of the barrel 1, with the top of the buffer cone 2 facing upwards, and a gap is left between the bottom edge of the buffer cone 2 and the inner wall of the barrel 1; a feed pipe 6 is provided in the lower part of the side wall of the barrel 1, and the feed pipe 6 is inclined towards the upper side of the buffer cone 2; and a discharge pipe 5 is provided at the bottom end of the barrel 1. The buffer cone 2 can buffer the slurry as it falls.

[0017] The axial direction of the buffer cone 2 coincides with the axial direction of the barrel 1.

[0018] The top of the barrel 1 is equipped with an exhaust pipe 4. The exhaust pipe 4 discharges gas, thereby achieving the separation of gas and liquid.

[0019] The bottom edge of the buffer cone 2 is connected to the lower part of the inner wall of the barrel 1 through several supports 3. The hollow structure design of the triangular supports 3 facilitates the slurry to pass through the buffer cone 2 and slide down, preventing the slurry from accumulating near the buffer cone 2.

[0020] The lower end of the barrel 1 is provided with a flared mouth 7, and the feeding pipe 5 is installed at the lower end of the flared mouth 7.

[0021] The distance between the bottom edge of the buffer cone 2 and the inner wall of the barrel 1 is 30mm.

[0022] The working process of this embodiment is as follows:

[0023] When the sampling valve is opened, the high-temperature and high-pressure slurry is discharged from the discharge pipe 6 and flows into the barrel 1. Then, the slurry hits the buffer cone 2 inside the barrel and is depressurized and decelerated. The generated gas is discharged from the exhaust pipe 4 at the top of the barrel 1, realizing gas-liquid separation. After being buffered and decelerated, the slurry flows out from the bottom discharge pipe 5 and enters the sampling cup, thereby achieving the purpose of safe sampling.
