Dismountable combined particle filling machine

Abstract

This invention relates to disassemble composite particles filling machine, which comprises the following: materials chute and material transmission device to send the particles in the chute to the destiny place, wherein the chute is supported by one rack above one base socket; the material transmission device is located on the base socket under the material exit mouth of chute; the transmission device can move back and forth by one dynamic driving system on the said base socket.

Description

technical field [0001] The invention relates to a detachable combined particle filling machine, in particular to a detachable combined particle filling machine for silver catalyst particles. Background technique [0002] Silver catalyst is an expensive product with huge associated economic benefits. The process of filling it into the reaction tube during use is extremely important, because whether the catalyst bed is bridged and whether the bed height is consistent will affect the bulk density of the bed and the uniformity of pressure drop, thereby affecting the efficiency of the catalyst and device safety. This not only affects the reputation of catalyst suppliers, but also affects the economic benefits of catalyst use, so both parties attach great importance to the work of catalyst loading. [0003] Domestic silver catalyst filling was first carried out manually with a sparger, but the speed was slow. At present, it has been replaced by manual filling in bags and tubes. ...

AI Technical Summary

Problems solved by technology

[0003] Domestic silver catalyst filling was initially filled manually with a distributor, but the speed was slow. At present, it has been replaced by manual filling in bags and tubes. This kind of filling has problems such as easy bridging, uneven pressure drop, more rework, and low efficiency.

There are also two foreign silver catalyst filling methods. One is the distributor method. This method requires a part of the new catalyst to be loaded into the reactor and then sucked out so that it cannot be reused. The sucked out catalyst accounts for about 9% of the filling volume, causing a lot of waste, and the filling speed is slow, basically do not use this method now

At present, catalyst suppliers generally provide machine filling services. Due to the large size and weight of various filling machines at present, and they cannot be disassembled, they cannot enter the reactor, and can only be connected outside the reactor through a hose to enter the reaction If the hose is too long, the slope will change greatly, which will easily cause the silver catalyst to be blocked and bridged in the hose due to poor fluidity, thus affecting the loading effect of the catalyst.
