Description

Technical Field

[0001] The utility model relates to the technical field of trace element fertilizer production equipment, in particular to an overflow pipe structure for a trace element fertilizer production silo. Background Art

[0002] Trace elements come from food and drinking water and are one of the nutritional elements. The absorption of various nutritional elements will affect each other. Only a reasonable diet can ensure sufficient trace element intake. Therefore, when fertilizers are produced, trace elements are added to the inside of the fertilizer. Specifically, the trace elements are filled inside the fertilizer production silo. However, since the silo contains liquid, when the liquid is filled too much, the liquid will overflow, and the overflowed liquid will flow into the interior of the processing device, which will then affect the production of fertilizers. In order to avoid liquid overflow, an overflow pipe is required to discharge the liquid that is about to overflow.

[0003] During the use of the overflow pipe, the overflow pipe mainly serves to drain and discharge excess liquid. However, in working condition, since the inside of the pipe is connected to the outside, harmful substances in the liquid and air inside the pipe are easy to flow back into the silo, and then easily react with the trace elements filled in the silo to cause damage. Therefore, a one-way valve is usually installed inside the overflow pipe to avoid the backflow of external gas and liquid when the liquid is not removed. However, when solid trace elements are discharged along the overflow pipe, solid impurities in the trace elements will adhere to the inside of the one-way valve, and long-term use will affect the liquid discharge effect. For this reason, we propose an overflow pipe structure for trace element fertilizer production silo. Utility Model Content

[0004] In view of the shortcomings of the existing overflow pipe structure for trace element fertilizer production silo, the utility model provides an overflow pipe structure for trace element fertilizer production silo, which has the advantages that when blockage occurs inside the overflow pipe, the rotating disk is rotated downward to drive the pull rope to move downward, and the first one-way valve blocks the inside of the auxiliary baffle, and the buckle drives the second one-way valve to move downward, that is, the second one-way valve can be opened inside the pipeline, and the accumulated liquid can be discharged through the inside of the filter net, thereby solving the problems raised in the above-mentioned background technology.

[0013] 1. The overflow pipe structure for the production silo of trace element fertilizer is installed inside the silo through the overflow pipe. At the same time, the rotating disk is rotated, and the rotating disk drives the pull rope to move downward. The pull rope drives the first one-way valve to block the inner wall of the auxiliary baffle. At the same time, when the pull rope moves downward, it drives the buckle to push the second one-way valve to move downward, that is, an opening is formed inside the filter screen, which avoids impurities from clogging the filter screen and the second one-way valve, resulting in the inability to drive liquid to be discharged.

At the same time, the liquid flows to the interior of the sealing sleeve 12, and the filter screen 16 filters the liquid. The first one-way valve 14 is blocked and the liquid flows to the upper end of the second one-way valve 17. After the liquid accumulates for a certain period, the second one-way valve 17 is driven to open under the action of hydraulic pressure, and the liquid can be discharged downward through the filter screen 16. At the same time, the rotating disk 20 is rotated, and the rotating disk 20 drives the pull rope 18 to move downward. The pull rope 18 drives the first one-way valve 14 to be blocked on the inner wall of the auxiliary baffle 13, thereby improving the sealing performance of the equipment. At the same time, when the pull rope 18 moves downward, the pull rope 18 drives the buckle 19 to push the second one-way valve 17 to move downward, thereby avoiding the second one-way valve 17 being stuck in the inside of the sealing sleeve 12, resulting in the problem that the accumulated liquid cannot be removed.
