[0002] Cellulose ethers are high molecular weight compounds obtained by chemical modification of natural cellulose. They are commonly used as thickeners and have wide applications in the construction, chemical, and medical fields. Cellulose ethers need to be granulated into pellets during processing. In the prior art, a utility model patent with patent application number 201922075222.0 discloses a disc-type granulator, which mainly consists of a granulation cylinder and a scraper. The granulation cylinder has multiple granulation holes. During pellet production, a paste-like material is added to the granulation cylinder, and then an extrusion mechanism forces the paste into columnar shapes through the granulation holes. Simultaneously, the scraper scrapes the material extruded outside the granulation cylinder onto a cooling cylinder, thus removing the columnar material and forming pellets. However, this method has the following problems: because the granulation holes on the granulation cylinder cannot be adjusted, it cannot produce pellets of different diameters according to customer needs, making it inconvenient and limiting its application.

Different perforated plates can be replaced at the right end of the extrusion cylinder according to production needs, which can produce granules of different diameters. It is convenient to use, has low limitations, and is highly practical.

[0004] To achieve the above objectives, this utility model provides a granulator for cellulose ether production, comprising a base plate, a support frame, an extrusion cylinder, and a belt conveyor. The extrusion cylinder is fixedly mounted on the base plate via the support frame. A chamber is provided inside the extrusion cylinder, and a feeding funnel communicating with the chamber is provided on the extrusion cylinder. The right end of the chamber is open. The belt conveyor is mounted on the base plate. The granulator also includes an extrusion mechanism, multiple perforated plates, a moving mechanism, a cutting mechanism, and a drying mechanism. The extrusion mechanism is mounted on the extrusion cylinder and has the function of extruding material. The multiple perforated plates are fixedly connected to each other, and each perforated plate has multiple granulation holes that communicate horizontally. The diameters of the granulation holes on the multiple perforated plates are different. The multiple perforated plates are connected to the opening at the right end of the extrusion cylinder by a sliding seal. The multiple perforated plates are all mounted on the moving mechanism, which is used for... Multiple perforated plates move, and a cutting mechanism is installed on the extrusion cylinder, which has a cutting function. A drying mechanism is located below the extrusion cylinder and has a drying function. When producing cellulose ether granules, the prepared paste-like raw material is added to the chamber of the extrusion cylinder. Then, according to the required granulation size, the moving mechanism drives multiple perforated plates to move in the front-back direction, so that the perforated plate with the appropriate granulation hole diameter moves to the right end of the extrusion cylinder opening. Then, the extrusion mechanism is opened, and the material in the chamber of the extrusion cylinder is conveyed to the right through the extrusion mechanism, so that the material is discharged through the granulation hole on the corresponding perforated plate. At the same time, the cutting mechanism cuts the columnar material discharged through the granulation hole, so that it forms granules that fall onto the drying mechanism.
