Description

Technical Field

[0001] This utility model belongs to the field of mineral processing equipment technology, specifically relating to a rapid conversion device for slurry conveying pipelines. Background Technology

[0002] Liquid pipeline transportation is widely used in various industries, but in actual production, the production process needs constant adjustment. To ensure stable production operation, two pipelines are generally configured for slurry transportation. This allows for switching to the other pipeline if one fails, ensuring continuous and stable production quality. Therefore, valves are installed at the pipeline inlets for control. To facilitate effective and timely adjustment of slurry transportation, considering the site environment and investment costs, one pipeline is typically controlled by an electric or pneumatic actuator, while the other is controlled manually. When the pneumatic valve control pipeline fails, using a manual valve is time-consuming and labor-intensive due to the erosion of the threaded transmission mechanism by the slurry. Taking a flotation site as an example, the slurry transportation of the inlet pipelines of two tailings slurry pumps is controlled by switching between pneumatic and manual valves. Due to the limited volume of the slurry tank, when the slurry pump fails, the pneumatic valve closes, and the manual valve takes a long time to open, resulting in slurry overflow. Manual operation increases the labor intensity and operational risks for workers, while also affecting the stability of system production and reducing production efficiency. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the conveying and filtering of slurry in the prior art, and to provide a pipeline rapid conversion device that is simple in structure, automatically operated, safe and reliable, and can effectively reduce labor intensity.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A rapid switching device for a slurry conveying pipeline includes two valve seats located at the bottom of a pool body. The two valve seats are arranged side by side and are respectively a first valve seat and a second valve seat. The bottom of the first valve seat is connected to a first pipeline, and the bottom of the second valve seat is connected to a second pipeline.

[0006] A first valve body is connected to a first valve seat, a vertical first valve stem is connected to the top of the first valve body, a driving component is connected to the top of the first valve stem, the driving component is fixed to the pool body, and the driving component drives the first valve stem to move in the vertical direction.

[0007] A second valve body is connected to the second valve seat, and a vertical second valve stem is connected to the top of the second valve body. A connecting rod is connected between the top of the second valve stem and the upper part of the first valve stem. A fixed support is hinged in the middle of the connecting rod, and the fixed support is connected to the pool body. Slide grooves are opened at the left and right ends of the connecting rod, and pins on the first valve body and the second valve body are respectively inserted into the slide grooves.

[0008] The first valve body and the second valve body are interlocked by a connecting rod. When the first valve body is opened, it causes the second valve body to close, and when the first valve body is closed, it causes the second valve body to open.

[0009] Furthermore, the driving component is a pneumatic actuator.

[0010] Furthermore, a guide is connected to the middle of the first valve stem and the second valve stem, and the guide restricts the movement of the first valve stem and the second valve stem in the vertical direction.

[0011] The beneficial effects of this utility model are as follows:

[0012] The device includes a valve body, a valve seat, and a valve stem. The two valve bodies are connected and controlled by a connecting rod between the valve stems. This utility model has a simple structure, is safe and reliable in operation, reduces production accidents caused by operational delays, ensures the stability of the production system, and has a wide range of applications.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0016] like Figure 1 As shown, a rapid conversion device for a slurry conveying pipeline includes two valve seats 1 located at the bottom of a pool body 7. The two valve seats 1 are arranged side by side and are respectively a first valve seat 1 and a second valve seat 1. The bottom of the first valve seat 1 is connected to a first pipeline 11, and the bottom of the second valve seat 1 is connected to a second pipeline 12.

[0017] A first valve body 2 is connected to a first valve seat 1. A vertical first valve stem 5 is connected to the top of the first valve body 2. A pneumatic actuator 8 is connected to the top of the first valve stem 5 and is fixed to the pool body 7. The pneumatic actuator 8 drives the first valve stem 5 to move vertically. A second valve body 3 is connected to a second valve seat 1. A vertical second valve stem 6 is connected to the top of the second valve body 3. A connecting rod 9 is connected between the top of the second valve stem 6 and the upper part of the first valve stem 5. A fixed support 10 is hinged to the middle of the connecting rod 9 and is connected to the pool body 7. Slide grooves are opened at both ends of the connecting rod 9. The pins on the first valve body 2 and the second valve body 3 pass through the slide grooves to prevent mechanical limitation during the movement of the connecting rod 9, the first valve stem 5, and the second valve stem 6. The length of the slide grooves is adjusted according to the length of the valve stem and the connecting rod 9.

[0018] The first valve body 2 and the second valve body 3 are interlocked by a connecting rod 9. When the first valve body 2 is opened, it causes the second valve body 3 to close, and when the first valve body 2 is closed, it causes the second valve body 3 to open. A guide 4 is connected to the middle of the first valve stem 5 and the second valve stem 6, and the guide 4 restricts the movement of the first valve stem 5 and the second valve stem 6 in the vertical direction.

[0019] The working principle of this utility model is as follows:

[0020] During operation, the pneumatic actuator 8 operates, opening the first valve body 2 by moving the first valve stem 5 upward. At the same time, the first valve stem 5 drives the connecting rod 9 to rotate around the fixed support 10, causing the second valve stem 6 to move downward and close the second valve body 3; or the first valve stem 5 moves downward to close the first valve body 2, while the first valve stem 5 simultaneously drives the connecting rod 9 to rotate around the fixed support 10, causing the second valve stem 6 to move upward and open the second valve body 3; thereby realizing the rapid switching of the control pipeline slurry transportation.
