Description

Purple pottery pugging machine

Technical Field

The utility model relates to a purple pottery pug mill.

Background

The earthenware clay is a basic raw material of the earthenware making industry, the quality of the earthenware clay is related to the quality of the made earthenware, the earthenware making becomes an independent door since the earthenware making industry comes birth, and the technical standard and the production equipment for the earthenware industry are generated. Since the mud refining forming method is applied to production, high quality and high efficiency are always the goals pursued by people. Equipment and processes are continually being modified to increase productivity and extrusion rates. In the German, American and Austria plant, the parallel screw throughput of 130mm in diameter is 1200kg/h and the parallel twin screw throughput of 169mm in diameter is 2000 kg/h; the conical twin-screw output was 1100 kg/h. According to the data, the improvement of the production efficiency is mainly attributed to the high-speed extrusion of the equipment. However, the development direction of the device is also towards high efficiency, high speed and intellectualization. The high rotating speed is always the development direction of the rotating speed of the screw, the rotating speed of the foreign screw can reach 600-. The previous twin screw had a length to diameter ratio of about 30. In the latter technological development, the aspect ratio of the twin screws has been developed to above 40. The length-to-diameter ratio of twin screws from Welding Engineering is 48 to 72.

The economics of an extrusion line are determined by the throughput. Before the 90 s, the linear speed of the parallel twin-screw extruder was 1-2m/min, and the output increased rapidly by the middle of the 90 s. This is because the linear velocity is increased from 2m/min to 4m/min due to the continuous development of the head and installation technology, the screw diameter is about 110mm, the length-diameter ratio is 20-23, and the output is 150-350 kg/h. By 1995, the screw diameter was 130mm and the throughput was 450-500 kg/h. As market demand continues to expand. Kwasi Maffei company develops a new generation of parallel twin-screw extruder, the diameter of the screw is 160mm, the length-diameter ratio is 26, and the yield directly reaches 1000 kg/h. The increase in extrusion speed has led to advances in extrusion technology. At present, the extrusion speed of a single cavity and a double cavity respectively reaches more than 6m/min and more than 4 m/min. In the aspect of equipment improvement, the diameter and the length-diameter ratio of a screw of the pugging machine need to be increased, the installation torque needs to be increased, the rotating speed of the screw needs to be increased, and the like, and the method is an effective method for improving the yield. Meanwhile, the pugging factory carries out technical innovation in the aspects of automatic control, on-line detection, accurate synchronization of a transmission system and the like of an extrusion production line, so that the product quality and the production stability can be improved.

The development direction of the extrusion molding technology can be seen in the following: (1) the labor cost is reduced, and the product can be automatically replaced in the production process; (2) the plasticizing capacity of the equipment is improved, the gear torque is increased, the length-diameter ratio of the screw is increased, and the productivity can be improved; (3) breaking the cooling limit; (4) the sensing technology, the control technology and the artificial intelligence technology are continuously applied to a control system of an extrusion production line, so that the product quality and the production stability are further improved.
