Embodiment 1

[0010] Embodiment 1: with reference to attached figure 1 and 2 . A dynamic screening and crushing device for bonded rubber particles, comprising a screw extruder 1, a collecting hopper 2, a pulverizer 3 and a blower 4, the outlet of the screw extruder 1 is located directly above the feed hopper of the pulverizer 3, and the screw extruder The discharge port of the discharge machine 1 is connected to the feed end of the sieve conveying pipe 11, the discharge port of the sieve conveying pipe 11 is directly facing the feed hopper of the pulverizer 3, and the discharge port of the pulverizer 3 is connected with one of the tee 5 , the other two links in the tee 5 are communicated with the air outlet of the blower 4 and the discharge pipe of the collecting hopper 2 through the air duct respectively. The wall of the sieve feed pipe 11 is a sieve-like structure 12, and the diameter of the sieve holes in the sieve-like structure 12 is a circular hole of 4mm. The sieve feeding pipe 11...

Embodiment 2

[0011] Embodiment 2: On the basis of Example 1, a method for dynamically screening and crushing bonded rubber particles, the screw extruder 1 extrudes the bonded rubber particles into the sieve feed pipe 11, and the sieve feed The spiral stirring rack 13 in the material pipe 11 breaks up the bonded rubber particles while driving the broken rubber particles to leak into the hopper 2 from the sieve holes on the wall of the sieve delivery pipe 11, but not into the hopper The bonded rubber of 2 is pulverized by pushing pulverizer 3, and the pulverized rubber particles are blown into the collecting hopper 2 by the wind blown out by blower 4. The wind speed of the wind blown by the blower 4 is greater than 3.5 m / s.

Abstract

The invention relates to a cohered rubber particle dynamic screening and smashing device with the functions of material conveying, cohered rubber particle scattering and material leakage, and a smashing and conveying method. The cohered rubber particle dynamic screening and smashing device comprises a spiral extruding machine, a material collecting hopper, a pulverizer and an air blower, wherein the discharging hole of the spiral extruding machine is located right above the feeding hopper of the pulverizer, the discharging hole of the spiral extruding machine is connected with the feeding end of a screening hole conveying pipe, the discharging hole of the screening hole conveying pipe directly faces the feeding hopper of the pulverizer, the discharging hole of the pulverizer is communicated with one way of a tee joint, and another two ways of the tee joint are communicated with an air pipe and the air blower respectively and are communicated with a discharging pipe of the material collecting hopper. The cohered rubber particle dynamic screening and smashing device has the advantages that the screening hole conveying pipe has a function of scattering cohered rubber particles, a function of a filter screen and a function of conveying the cohered rubber particles to the pulverizer due to the design of the screening hole conveying pipe, and besides, the air blower is adopted for conveying the rubber particles pulverized by the pulverizer, the manual operation is not required and pulverized rubber particles can be conveyed automatically.

Description

technical field [0001] The invention relates to a dynamic screening and crushing device and crushing and conveying method for bonded rubber particles, which not only have the function of conveying materials, but also have the function of breaking up bonded rubber particles and have the function of material leakage, belonging to the secondary processing of rubber particles Equipment manufacturing field. Background technique [0002] CN202683275 U, the name "crushing fan", includes a volute with a gas-material inlet located in the axial center and a gas-material outlet located in the circumferential direction, and is arranged in the axial center of the volute and can be driven by a drive mechanism to rotate The main shaft is equipped with a fan blade centrifugal air supply structure. Between the radial distal rotation track of the fan blade and the inner peripheral wall of the volute, there is a crushing space that can divide the volute space into a centripetal part and a cent...
