Screw feeder easy to clean

Abstract

The invention provides a screw feeder easy to clean. The screw feeder comprises a hopper, a material conveying bin, a material conveying drive motor and a discharging port. The material conveying drive motor is connected with the tail end of the lower portion of a spiral rotating shaft in the material conveying bin, and drives the spiral rotating shaft to rotate. The spiral rotating shaft is of a hollow structure, and an inner sleeve of a hollow structure is coaxially sleeved with the spiral rotating shaft. The outer diameter of the inner sleeve is equal to the inner diameter of the spiral rotating shaft, and an inlet-outlet opening communicating with the interior of the inner sleeve is formed in the upper portion of the inner sleeve. A plurality of shaft core holes are vertically distributed in a shaft core of the spiral rotating shaft. Inner sleeve holes are distributed in the positions, corresponding to the shaft core holes, of the inner sleeve. The parts, where the inner sleeve holes are not distributed, on the inner sleeve can close the shaft core holes at the same time under a certain nesting state. According to the screw feeder, equipment can be efficiently cleaned under the condition that detaching is not conducted.

Description

technical field [0001] The invention belongs to the technical field of cement building materials equipment, and in particular relates to an easy-to-clean screw feeder, which also has the advantage of being convenient for adjusting the inclination angle. Background technique [0002] With the rapid development of my country's national economy, the demand for cement products in construction projects is getting higher and higher. Different production lines of various cement products, including cement pipes, cement plates, cement bricks, cement tiles, cement abrasives, etc., often have different production requirements. and production conditions. Screw feeder is a commonly used feeding equipment in the production of cement products. [0003] The general screw feeder is often fixed in a certain place on the production line or construction site. Because different production lines or construction environments often put forward different requirements for the inclination angle of the...

Problems solved by technology

However, on the one hand, due to the long length of the delivery bin and the screw shaft installed therein, its disassembly is very tedious and laborious; on the other hand, the helical structure of the screw shaft and the relatively narrow feeding space of the delivery bin also make cleaning Difficult to carry out effectively
