[0002] Whether it is industrial projects, municipal engineering, or civil engineering, there will be situations where multiple conveying devices need to be switched and used as spares for each other under various working conditions in some places for conveying liquids or slurries such as ore slurries; there are multiple pipelines suitable for various working conditions and used as spares for each other. This situation usually requires a large number of switching valves and pipe fittings to achieve, which is very troublesome for operation and maintenance, difficult to improve production efficiency, brings great inconvenience to production and maintenance, and has a large investment amount.

[0003] At present, the existing slurry conveying pipeline switching requires too many pipe fittings and valves, and mostly has the following deficiencies: during the process of slurry conveying pipeline switching, due to the overly complex switching pipeline, the operation difficulty is increased, the maintenance is difficult, the investment amount is large, the production efficiency is poor, and due to the poor wear resistance of the pipe fittings and short service life, the production efficiency is seriously affected. In view of the above problems, a slurry conveying pipeline switching pipe fitting is proposed. Summary of the Utility Model

[0004] The utility model provides a slurry conveying pipeline conversion pipe fitting, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problem of large operation difficulty in pipeline switching existing in the existing slurry conveying pipeline due to its complex structure.

[0005] To solve the above problems, a slurry conveying pipeline switching pipe fitting described in the utility model includes a distribution barrel, a slurry inlet pipe, a slurry outlet pipe, and a control valve. At least three slurry inlet pipes fixedly communicated with the inner side of the distribution barrel are arranged at intervals on the left and right sides of the front side of the distribution barrel, and at least three slurry outlet pipes fixedly communicated with the inner side of the distribution barrel are arranged at intervals on the left and right sides of the rear side of the distribution barrel. A control valve is fixedly installed on the outer side of each slurry inlet pipe and each slurry outlet pipe; a lower connecting flange is arranged on the outer side of the upper part of the distribution barrel, a blind plate is arranged on the top of the distribution barrel, an upper connecting flange matching with the lower connecting flange is arranged on the outer circle of the blind plate, and the upper connecting flange and the lower connecting flange are connected together by bolts; wear-resistant rubber is arranged on the bottom of the blind plate, the inner wall of the distribution barrel, the inner wall of the slurry inlet pipe, and the inner wall of the slurry outlet pipe.

[0006] A handle is arranged at the center of the top of the above-mentioned blind plate.

[0007] Wear-resistant rubber is arranged on the top of the above-mentioned lower connecting flange.

[0008] The above-mentioned control valve is a slag valve or a gate valve.

[0009] The utility model is installed in the middle of all slurry inlet pipelines and slurry outlet pipelines. When connection difficulties occur during connection, rubber force transmission joints or pressure-resistant rubber steel wire hoses can be installed on the slurry inlet and outlet pipelines to correct the joint deviation and smoothly install the pipe fittings in place, thus completing the installation of the pipeline of this device. Subsequently, the connected equipment or the slurry outlet pipeline is connected to control the switching of slurry inlet and outlet. The pipeline structure is simple, and the switching operation is also simple. Multiple conveying devices can be switched with each other and used as backups under various working conditions, improving the efficiency of slurry discharge switching.
