Raw material screening equipment used for fire hose glue layer production and application method of raw material screening equipment

Abstract

The invention discloses raw material screening equipment used for fire hose glue layer production. The raw material screening equipment comprises a screening box and an air cylinder. The screening boxcomprises a scattering area and a separating area which communicate with each other. An opening is formed in the upper portion of the scattering area, and the diameter of the scattering area is 2-4 times the diameter of the separating area. The air cylinder is fixed above the screening box, a telescopic rod of the air cylinder is connected with a rotating shaft through a motor, two sets of up-and-down horizontal first cylinders and second cylinders are arranged on the side face of the rotating shaft, the distance between the tail ends of the second cylinders and the side wall of the separating area is smaller than 2 mm, multiple elastic press blocks arranged at intervals are arranged below the second cylinders, multiple discharging holes are formed in the lower plane of the separating area, and a discharging pipe and a connecting and conveying device are arranged below the discharging holes. According to the raw material screening equipment, the rotating shaft rotates up and down within the limited range, a toothed compression door is arranged below a lower knocking cylinder, and therefore materials in the screening box are screened and separated, and the sizes of the materials are ensured; and the raw material screening equipment is reasonable in structural design, convenient to use and good in separating effect and has good application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of particle screening equipment, and in particular relates to a raw material screening equipment used for the production of fire hose rubber layers and a method for using the same. Background technique [0002] At present, the fire hose is generally divided into three layers from the inside to the outside, namely the inner rubber layer, the braided layer, and the outer rubber layer. The inner rubber layer and the outer rubber layer are extruded from rubber particles and other additives. Among them, the rubber particles The quality of raw materials is very important. The ready-made rubber particles are easy to stick together due to high temperature problems when they are discharged during the production process. It is necessary to separate the sticky particle clusters. The existing separation technology generally uses a material sieve for screening, but the rubber particles that form agglomerates need to be s...

AI Technical Summary

Problems solved by technology

The existing separation technology generally uses a material sieve for screening, but the rubber particles that form agglomerates need to be screened and separated manually, which is labor-intensive and low-efficiency, and needs to be improved.
