Problems solved by technology

[0002] In the existing spinning work of hollow fiber ultrafiltration membranes, most of the equipment is a spinning machine with only one spinneret installed for spinning. If you want to install multiple spinnerets, you must install multiple spinning machines. Machine can only be realized, which is not conducive to the automation of spinning and collection, and is not conducive to large-scale spinning of hollow fiber ultrafiltration membranes

Abstract

The invention discloses an assembled type spinneret plate with a plurality of spinning nozzles, which comprises an upper spinneret plate, a middle spinneret plate and a lower spinneret plate, wherein the upper spinneret plate is provided with an inner condensing liquid inlet, a constant temperature liquid inlet, a membrane liquid inlet and a constant temperature liquid outlet. The inner condensing liquid inlet is connected with a middle spinneret plate liquid delivery tray on the middle spinneret plate by an upper spinneret plate liquid delivery sleeve. A middle spinneret plate liquid delivery sleeve is installed below the middle spinneret plate liquid delivery tray. The middle spinneret plate liquid delivery sleeve is connected with the spinning nozzles. The internal parts of the upper spinneret plate, the middle spinneret plate and the lower spinneret plate are provided with membrane liquid channels. The internal parts of the middle spinneret plate and the lower spinneret plate are provided with constant temperature liquid channels. According to the assembled type spinneret plate with multiple spinning nozzles disclosed by the invention, a plurality of spinning nozzles are assembled on the spinneret plate, so that the spinneret plate is simple, compact and integrated in the structure. The membrane-making liquid channel, the inner condensing liquid channel and the constant temperature liquid channel are uniformly distributed and liquid flows smoothly, so that the sealing property and pressure resistance of the spinneret plate are realized. In addition, stable and reliable high temperature, low temperature and constant temperature of the liquid is guaranteed, and different temperatures can be controlled. Therefore, the assembled type spinneret plate disclosed by the invention is suitable for different membrane-making formulae and spinning under different membrane-making techniques as well as spinning various hollow fiber membranes on a large scale.

Description

technical field [0001] The invention relates to the technical field of hollow fiber ultrafiltration membrane processing, in particular to a spinneret for outputting membranes. Background technique [0002] In the existing spinning work of hollow fiber ultrafiltration membranes, most of the equipment is a spinning machine with only one spinneret installed for spinning. If you want to install multiple spinnerets, you must install multiple spinning machines. It can only be realized by a machine, which is not conducive to the implementation of automatic spinning and collection, and is not conducive to large-scale spinning of hollow fiber ultrafiltration membranes. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies and defects in existing hollow fiber ultrafiltration membrane spinning equipment, the present invention provides a multi-nozzle spinneret that can install multiple spinnerets on one spinning machine. [0004] The technical solut...
