The device for recoil operation transports water or gas to a bin or a column through a main pipeline and a branch pipeline for recoil operation, thereby preventing the material in the bin or the column from compacting. The device has the advantages of convenient sewage discharge, prevention of pipe blockage, and convenient installation and maintenance, thus overcoming the problems of easy pipe blockage and difficult installation and maintenance operations.

[0004] In order to achieve the above technical purpose, the technical solution adopted by the utility model is:

[0005] A device for backflushing operation, comprising: a column, a plurality of main pipelines, a plurality of branch pipelines, a control valve, a check valve and a drain valve;

The branch pipelines are evenly distributed in the main pipeline, which is convenient for layered connection with the silo or column to achieve layer-by-layer water and gas supply.

[0023] The specific implementation of the utility model is further described below according to the accompanying drawings:

[0024] like Figure 1 to Figure 2 As shown, a device for backflushing operation includes: a bin body or a column 1, a plurality of main pipes 2, a plurality of branch pipes 3, a control valve 4, a check valve 5 and a drain valve 6.

[0025] The plurality of main pipes 2 are perpendicular to the ground at 90 degrees and are distributed around the bin or column 1. A drain valve 6 is connected to the bottom of each main pipe 2. Each main pipe 2 is connected to a plurality of branch pipes 3. A control valve 4 and a check valve 5 are provided on each branch pipe 3. The plurality of branch pipes 3 are connected to different positions on the bin or column 1. The main pipe 2 and the branch pipe 3 are used to transport water or gas into the bin or column 1 for backwashing.

[0026] In this embodiment, the plurality of main pipes 2 are evenly spaced and distributed around the bin body or column 1 .

[0027] In this embodiment, there are at least four main pipelines 2.

[0028] In this embodiment, the main pipeline 2 is evenly spaced from top to bottom and is connected with multiple layers of branch pipelines 3 , and each layer of branch pipelines 3 includes multiple branch pipelines 3 .

[0029] The multiple branch pipes 3 located at the same height layer are connected to the silo or column 1 at different positions, and the connection positions of the multiple branch pipes 3 located at the same height layer and the silo or column 1 are evenly spaced along the circumferential direction.

[0030] In this embodiment, the branch pipeline 3 is arranged horizontally.

[0031] In this embodiment, the control valve 4 is a flow control valve or a pressure control valve.

[0032] In this embodiment, the main pipeline 2 is made of DN100 seamless steel pipe, the branch pipeline 3 is made of aluminum-plastic pipe, and the silo or column 1 is made of steel.

[0033] In this embodiment, the main pipeline 2 and the branch pipeline 3 are connected through a short circuit (i.e., a short circuit pipe), one end of the short circuit is threadedly connected to the main pipeline 2 or connected by a flange bolt, and the other end of the short circuit is threadedly connected to the branch pipeline 3 or connected by a flange bolt.

[0034] In this embodiment, a short-circuit (i.e., a short-circuit tube) is welded to the reserved through hole on the bin body or column 1, and the other end of the short-circuit is threadedly connected to the branch pipe 3 or connected by a flange bolt.

[0035] The control valve 4, the check valve 5 and the drain valve 6 of this embodiment can be manual or automatic. If they are automatic, they are connected to a power supply.

[0036] After the material enters the silo or column 1, it settles. The main pipeline 2 transports water or gas into the branch pipeline 3. The water pressure or air pressure is adjusted by the control valve 4. The branch pipeline 3 is connected to the silo or column 1. After the water or gas enters the main pipeline 2, it enters the silo or column 1 through the branch pipeline 3 for backwashing to prevent the material in the silo or column 1 from hardening. A sewage valve 6 is installed at the bottom of the main pipeline 2 to prevent the material from entering the main pipeline 2 for sewage discharge. At the same time, a check valve 5 is installed before the branch pipeline 3 is connected to the silo or column 1 to prevent the material from entering the branch pipeline 3; a control valve 4 is installed before the branch pipeline 3 is connected to the silo or column 1 to facilitate the adjustment of water pressure or air pressure. The main pipeline 2 is 90° vertical to the ground and distributed around the silo or column 1, which is convenient for uniform water and air supply. The branch pipelines 3 are evenly distributed in the main pipeline 2, which is convenient for layered connection with the silo or column 1 to achieve layer-by-layer water and air supply.

[0037] After the ore slurry enters the silo or column 1, compaction is likely to occur. Water or gas is transported into the silo or column 1 through the main pipeline 2 and the branch pipeline 3 for recoil to prevent compaction from occurring. At the same time, it is easy to install and maintain operations, and can meet the production needs of recoil operations. The recoil water or gas of this embodiment is transported through not limited to four main pipelines 2 that are perpendicular to the ground. When the main pipeline 2 transports water or gas, a drain valve 6 is installed at the bottom of the main pipeline 2 to prevent materials from entering the main pipeline 2 and causing blockage. The main pipeline 2 is evenly distributed around the silo or column 1. The main pipeline 2 is easy to lay, and the branch pipelines 3 are evenly distributed in the main pipeline, which is convenient for layered installation and connection of the silo or column 1. The size of the recoil water or gas can be manually adjusted by the control valve 4 to meet production needs.

[0038] On the basis of the original, this embodiment adds four DN100 seamless steel pipes uniformly distributed vertically at 90 degrees around the bin body or column, and connects the bin body or column 1 through four main pipes evenly distributed at intervals through aluminum-plastic pipes. At the same time, a drain valve 6 and a check valve 5 are installed to realize functions such as convenient adjustment of water pressure or air pressure, prevention of slurry from entering the backwashing pipe, and timely discharge of sewage, so as to realize the normal operation of the backwashing operation.

[0039] The vertically arranged main pipeline 2 and the horizontally arranged branch pipeline 3 of this embodiment are easier to process, install and maintain than the annular backwash water pipe or air pipe in the prior art; and the main pipeline 2, the branch pipeline 3, and the branch pipeline 3 are connected to the bin body or column 1 through a short circuit, which is convenient for disassembly and maintenance.

[0040] Compared with the existing devices, this embodiment has the advantages of convenient sewage discharge, prevention of pipeline blockage, easy installation and maintenance, and layered layout, which overcomes the problems of easy pipeline blockage and difficult processing, installation, maintenance and operation.
