Automatic solid particle packing compression device

Abstract

The invention discloses an automatic solid particle packing compression device. Cylindrical bases are arranged along the peripheral direction of a cover cap of an adsorption tower at intervals, and are internally provided with compression rods penetrating through the tower cap; the lower ends of the compression rods are connected with a packing pressing plate in the adsorption tower; the tops of the bases are provided with cylindrical top bases; the top bases are internally provided with drive screw rods matched with fixed swivel nuts; the lower ends of the drive screw rods are connected with the upper ends of the compression rods; the drive screw rods are connected with a drive shaft; the drive shaft is connected with a ratchet-pawl mechanism connected with a drive plate driving mechanism. According to the invention, multiple synchronous compression devices run synchronously, so that the displacement amount of each compression point is consistent, the compression force acts on packing equally and stably so as to prevent packing side leakage caused by obliqueness of the packing pressing plate due to unbalanced multi-point compression force; a pore plate can be effectively prevented from jumping after compression.

Description

Technical field [0001] The invention relates to the field of chemical machinery, in particular to an automatic compaction device for solid particle fillers. Background technique [0002] In the gas separation equipment manufacturing industry, especially in the pressure swing adsorption gas separation equipment, violent pressure fluctuations have a great impact on the solid particle packing, and it is easy to cause the fluidization of the solid particle packing. Limiting the fluid movement speed can prevent fluidization. But when the fluid movement speed cannot be reduced in the process, auxiliary equipment such as a particle packing compaction device is needed to control the particle movement. In the pressure swing adsorption process, the pressure swing adsorption gas separation equipment mainly relies on the adsorption capacity and adsorption rate of the adsorbent for each component gas in the gas under different pressures to achieve the purpose of separating each component gas....

Problems solved by technology

[0003] In the prior art, the patent No. ZL200920284082.1 describes a pressure swing adsorption oxygen generation adsorption tower mechanical compression device, which uses a compression screw and a porous platen, wherein the compression screw ensures The packing is pressed at any time under the circumstances, and the porous platen is pressed against the wall of the adsorption tower by pressing the supporting wire mesh to ensure that the packing does not leak sideways. The level cannot be adjusted; during weekly or monthly regular compaction, the control of compaction displacement and strength is high, which may easily cause the pressure plate to deflect and cause packing leakage, or excessive compaction force may cause packing damage or even pulverization

As described in the patent No. ZL98215653.7 and the patent No. ZL200820153444.9, the use of cylinder compression can realize the constant compression of the packing, and the compression force is determined by the piston area of ​​the compression cylinder. The supporting hydraulic backstop system can effectively prevent The orifice plate jumps due to excessive fluid pressure fluctuations. However, this type of device is limited by the cylinder manufacturing process. Due to the limited pressing surface of the cylinder, during the pressing displacement process, if the pressing surface is inclined, the piston of the pressing cylinder is easy to get stuck. Easy to cause filler pulverization
