AI Technical Summary
During the feeding process of wet metal catalyst, the catalyst is easily sprinkled and air-dried, resulting in the risk of residual burning in the feeder.
A safe feeding device for wet metal catalysts is designed, including the main body of the feeding bin, annular water leakage tray, water filling pipe and drain pipe. The device receives the sprinkled catalyst through an annular water-connected leaking plate and adds water. The drain pipe discharges the water containing the catalyst into the feed silo, flushs the inner wall and forms a wet water seal to prevent the catalyst residue from drying.
It effectively prevents the risk of drying and burning of catalyst residues, reduces operating costs, and is suitable for the use of wet metal catalysts.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of wet metal catalysts, and particularly to a safe feeding device for wet metal catalysts. Background Art
[0002] Metal catalysts are widely used in chemical reactions, mainly because of their good reaction activity. However, they also bring a high risk of flammability, which has always been a headache and a problem that must be taken seriously in chemical enterprises.
[0003] At present, the wet storage and transportation of wet metal catalysts have greatly reduced the flammability risk during catalyst feeding. However, there is still a risk of combustion caused by the drying of the residues after the catalyst is spilled during feeding and the drying of the sticky materials on the inner wall of the feeder. Summary of the Invention
[0004] To solve the above problems, the present invention discloses a safe feeding device for wet metal catalysts.
[0005] The specific scheme is as follows:
[0006] A safe feeding device for wet metal catalysts, characterized in that: it includes a feeding bin main body. The middle part of the top surface of the feeding bin main body is a feeding port for feeding the catalyst. A circular leakage water receiving tray is arranged around it. The circular leakage water receiving tray is used to receive the spilled catalyst during feeding and hold water. The upper end of its side wall is provided with a water adding pipe for adding water, and the lower end of the side wall is provided with a drain pipe communicating with the inner cavity of the feeding bin main body. The drain pipe is used to discharge the water containing the catalyst into the feeding bin to wash the catalyst stained on the inner wall of the feeding bin main body and form a wet water seal at the bottom of the feeding bin main body. Thus, it can prevent the drying of the catalyst residues in the bin, and this part of the liquid will be put into the reaction together with the next batch of catalysts. At the same time, the circular leakage water receiving tray continues to add water for the next batch of feeding.
[0007] Further, the lower port of the drain pipe is placed at the upper end of the inner wall of the feeding bin main body.
[0008] Further, a water adding valve and a draining valve are respectively installed on the water adding pipe and the drain pipe.
[0009] Further, the inner wall of the central hole of the circular leakage water receiving tray closely adheres to the outer wall of the lower end of the feeding port.
[0010] Further, a pneumatic hammer is also installed on the side wall of the feeding bin main body.
[0011] The beneficial effect of the present invention is that: the structure of the present invention is ingenious, the investment cost is small, nitrogen protection is not required, it is suitable for wet metal catalysts, and the operation cost is low. Brief Description of the Drawings

[0016] The present invention will be further clarified below in conjunction with the accompanying drawings and specific implementation manners. It should be understood that the following specific implementation manners are only used to illustrate the present invention and not to limit the scope of the present invention.
[0017] As shown in the figure, the present invention provides a safe feeding device for wet metal catalysts, including a main body 1 of the feeding bin. The middle part of the top surface of the main body 1 of the feeding bin is a feeding port 2 for feeding catalysts. A circular water leakage receiving tray 3 is arranged around it. The circular water leakage receiving tray 3 is used to receive the catalysts spilled during feeding and contains water. A water adding pipe for adding water is arranged at the upper end of its side wall, and a drain pipe communicating with the inner cavity of the main body 1 of the feeding bin is arranged at the lower end of the side wall. The drain pipe is used to discharge the water containing catalysts into the feeding bin to wash the catalysts adhered to the inner wall of the main body 1 of the feeding bin and form a wet water seal at the bottom of the main body 1 of the feeding bin. Thereby, it prevents the catalyst residues in the bin from drying, and this part of the liquid will be fed into the reaction together with the next batch of catalysts. At the same time, the circular water leakage receiving tray continues to add water for the next batch of feeding.
[0018] In this embodiment, the lower port of the drain pipe is placed at the upper end of the inner wall of the main body 1 of the feeding bin.
[0019] In this embodiment, a water adding valve 4 and a drain valve 5 are respectively installed on the water adding pipe and the drain pipe in a matching manner.
[0020] In this embodiment, the inner wall of the central hole of the circular water leakage receiving tray 3 closely adheres to the outer wall of the lower end of the feeding port 2.
