[0010] See also Figure 1 , 2 , a mine wet conveying pipeline interchange device, a ore collecting box 1 made of ceramic tubes with both sides blocked and welded; two conveying pipelines, namely, a feed pipe 2 and a discharge pipe 6, a second feed pipe 7 and a second discharge pipe 11, are symmetrically welded on both sides of the ore collecting box 1; on the two conveying pipelines, a feed electric valve 4, a discharge electric valve 5, a second feed electric valve 9, and a second discharge electric valve 10 are installed on both sides of the ore collecting box 1 respectively; at the front end of the feed electric valve 4 and the second feed electric valve 9, a feed sewage valve 13 and a second feed sewage valve 15 are installed at the bottom of the feed pipe 2 and the second feed pipe 7; at the rear end of the discharge electric valve 5 and the second discharge electric valve 10, a discharge sewage valve 14 and a second discharge sewage valve 16 are installed at the bottom of the discharge pipe 6 and the second discharge pipe 11; a flushing water pipe 12 is installed at the upper part of the ore collecting box 1 and the vertical center position. The ore feeding pipe 2 and the ore discharging pipe 6 , the second ore feeding pipe 7 and the second ore discharging pipe 11 should be at the same horizontal position on both sides of the ore collecting box 1 .
[0011] The mine wet conveying pipeline interchange device is a 1.2m long φ480mm ceramic tube, which is sealed and welded on both sides to form a collection box 1; on both sides of the collection box, two φ159mm conveying pipelines are symmetrically welded in a horizontal position, namely, the feed pipe 2 and the discharge pipe 6, the second feed pipe 7 and the second discharge pipe 11; on the two conveying pipelines, the distance between the two sides of the collection box 1 is 500mm, and the feed electric valve 4, the discharge electric valve 5 and the second feed electric valve 9, the second discharge electric valve 10 are installed respectively. Electric valve 10; 500mm from the front end of the feeding electric valve 4 and the second feeding electric valve 9, a feeding sewage valve 13 and a second feeding sewage valve 15 are installed at the bottom of the feeding pipe 2 and the second feeding pipe 7; 500mm from the rear end of the discharge electric valve 5 and the second discharge electric valve 10, a discharge sewage valve 14 and a second discharge sewage valve 16 are installed at the bottom of the discharge pipe 6 and the second discharge pipe 11; a flushing water pipe 12 is installed at the upper part of the ore collecting box 1 and at the vertical center.
[0012] The electric valve is mainly used to prevent liquid leakage or liquid backflow. You can purchase electric valves of corresponding sizes according to the diameter of the pipeline.
[0013] The purpose of the flushing water pipe is to prevent the accumulation of mineral materials and to avoid the blockage of the ore collecting box when the pipeline is interchanged. The pipe diameter is generally DN25, and DN20 can also be used. The selection standard is to ensure that the deposited mineral materials in the ore collecting box can be quickly dispersed when the system is shut down.
[0014] The function of the blowdown valve is to discharge the wet materials in the pipeline in time when the system is shut down to prevent the materials from settling or freezing of the outdoor pipelines in winter. For the selection of the blowdown valve size, take the φ159mm conveying pipeline as an example, select DN100, which is the standard for quickly discharging the accumulated ore in the pipeline.
[0015] Working principle:
[0016] When transporting materials through pipelines:
[0017] The feed sewage valve 13, the discharge sewage valve 14, the second feed sewage valve 15, the second discharge sewage valve 16, and the flushing water pipe 12 are in closed state.
[0018] Case 1: Close the second feeding electric valve 9 and the second discharging electric valve 10, open the feeding electric valve 4 and the discharging electric valve 5, start the pump 3, and the wet material enters the collecting box 1 through the feeding pipe 2, and enters the next process after passing through the discharging pipe 6.
[0019] Interchange of pipelines in case of failure:
[0020] ① When pump 3 fails and cannot continue to operate, pump 3 is stopped, the electric valve 4 for feeding is closed, the second electric valve 9 for feeding is opened, the second pump 8 is opened, and the wet material enters the collecting box 1 through the second feeding pipe 7, and enters the next process after passing through the discharge pipe 6.
[0021] ② When the discharge pipe 6 leaks or other failures occur and the material transportation needs to be stopped, the second discharge electric valve 10 is opened and the discharge electric valve 5 is closed. The wet material enters the next process after passing through the second discharge pipe 11.
[0022] Case 2: Close the electric valve 4 for feeding and the electric valve 5 for discharging, open the second electric valve 9 for feeding and the second electric valve 10 for discharging, start the second pump 8, and the wet material enters the collecting box 1 through the second feeding pipe 7, and enters the next process after passing through the second discharging pipe 11.
[0023] Interchange of pipelines in case of failure:
[0024] When the second pump 8 fails and cannot continue to operate, the second pump 8 is stopped, the second ore feeding electric valve 9 is closed, the ore feeding electric valve 4 is opened, the pump 3 is turned on, and the wet material enters the ore collecting box 1 through the ore feeding pipe 2, and enters the next process after passing through the second ore discharge pipe 11.
[0025] When the second ore discharge pipe 11 leaks or has other faults and needs to stop transporting materials, the ore discharge electric valve 5 is opened and the second ore discharge electric valve 10 is closed. The wet materials enter the next process after passing through the ore discharge pipe 6.
[0026] Use of flushing water pipe: When the system is shut down for a long time and there may be material deposits in the ore collecting box 1 and it cannot be guaranteed to be unobstructed, open the flushing water pipe 12, open the ore feeding and discharge valves on the prepared conveying pipeline, flush out the deposited materials, close the drain valves of each part, and then start the equipment.
[0027] Use of drain valve: When the system is shut down, open the corresponding feed drain valve 13 or 15 and discharge drain valve 14 or 16 according to the pipeline route before shutdown, and discharge the accumulated ore in the running pipeline in time to prevent wet materials from depositing and clogging in the pipeline, and freezing of the pipeline in winter.
