Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a rubbing crusher filter equipment, including the base 1 that wholly is the quadrangular prism form, four gyro wheels with the central symmetric distribution of base 1 are installed to the bottom of base 1. The base 1 is provided with a primary crushing device 2 and a secondary crushing device 3 from top to bottom in sequence.

The primary crushing device 2 comprises a primary crushing chamber 4 which is quadrangular prism-shaped as a whole, and a primary shearing assembly 5 for crushing materials is arranged in the primary crushing chamber 4. The primary crushing chamber 4 is provided with a square primary feed inlet 6 and a primary discharge outlet 7, and the primary feed inlet 6 is welded with a feeding device 9 which is integrally funnel-shaped. Primary discharge gate 7 department welding has the primary filter assembly 10 of slope setting, and the inclination is for setting up to 35. The side wall of the primary crushing chamber 4 is provided with a primary coarse material outlet 8 near the lower end of the primary filter assembly 10. The outer wall of the primary crushing chamber 4 is provided with a dust suction device 11 for absorbing flying dust generated in the crushing process. The secondary crushing device 3 comprises a secondary crushing chamber 12 which is quadrangular prism-shaped as a whole, a secondary crushing assembly 13 for crushing materials is arranged in the secondary crushing chamber 12, and a secondary feeding hole 14 and a secondary discharging hole 15 are formed in the secondary crushing chamber 12. The secondary feed inlet 14 receives the primary coarse material outlet 8, so that the filtered material in the primary crushing chamber 4 enters the secondary crushing chamber 12 for further crushing.

Referring to fig. 1 and 2, the primary filter assembly 10 includes a generally quadrangular prism-shaped vibratory screen 16 and a vibratory drive 17 for powering the vibratory screen 16. The vibration driver 17 is a vibration motor. The vibrating screen 16 is connected to the inner wall of the primary crushing chamber 4 through an elastic member 18, the elastic member 18 is a spring, one end of the spring is welded to the inner wall of the primary crushing chamber 4, and the other end of the spring is welded to the bottom of the vibrating screen 16. The side of the vibrating screen 16 close to the primary shearing assembly 5 is welded with a blocking support 19 protruding from the surface of the vibrating screen 16. The blocking support 19 comprises a transverse support 20 and a vertical support 21. In one case, the lateral support 20 is arc-shaped, and the arc-shaped projection direction of the lateral support 20 is towards the primary coarse material outlet 8. The curved transverse supports 20 help to block more material to be screened, extending the residence time of the material on the vibrating screen 16, so that the material is screened more significantly. Referring to fig. 3, in another case, the lateral support 20 is disposed to be inclined with the inclined lower end of the lateral support 20 facing the primary coarse material outlet 8. The obliquely arranged transverse support 20 has the same effect as the curved transverse support 20.

A primary material guide plate 22 in a beam mouth shape is welded on the inner wall of the primary crushing chamber 4 between the vibrating screen 16 and the primary shearing assembly 5, and the beam mouth direction faces the vibrating screen 16. The primary guide plate 22 is advantageous to make the material slide down from the middle of the vibrating screen 16, thereby improving the screening effect.

The implementation principle of the embodiment is as follows: the materials are put into a feeding device 9, primary crushing is carried out through a primary crushing chamber 4, the materials after primary shearing fall onto a vibrating screen 16 to be screened under the constraint of a primary guide plate 22, and a vibrating driving piece 17 drives the vibrating screen 16 to vibrate. During the vibration process of the vibrating screen 16, the elastic member 18 is continuously compressed and elongated, and the material meeting the requirements of the vibrating screen 16 leaks out of the vibrating screen 16 and is finally discharged from the primary discharge hole 7. The material left on the vibrating screen 16 is discharged from the primary coarse material outlet 8 by the vibrating screen 16 and then falls to the secondary inlet 14. In this process, the dust suction device 11 absorbs the fly ash generated in the primary grinding chamber 4, thereby preventing the generation of dust mist and the pollution of the surrounding environment. The secondary crushing chamber 12 further crushes the material screened out on the vibrating screen 16 and finally discharges it through a secondary discharge opening 15. In conclusion, compared with the common screen, the vibrating screen 16 has more obvious screening effect, and improves the crushing efficiency and the crushing quality.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
