Description

Technical Field

[0002] With the gradual acceleration of the pace of urban construction, the use of natural sand has also gradually increased. Since natural sand is a non-renewable resource, it is gradually in short supply. Therefore, solid waste resources such as nickel slag, coal gangue, iron tailings, and stone chips are utilized, and a certain proportion of machine-made sand is added to prepare special fine aggregate for mortar. However, due to the problems of poor particle shape and unreasonable grading of solid waste resources such as stone chips, nickel slag, coal gangue, and iron tailings, they cannot directly replace the machine-made sand currently used in mortar, and the solid waste resources need to be crushed and screened.

The beneficial effects are: the screening mechanism and the crushing mechanism are provided, the gap between the slide on the screening mechanism and the screening slope can be adjusted by sliding the slide within the blanking plate, which facilitates the adjustment of the screening conditions, and two crushing methods are provided: a crushing wheel and a crushing column, so that larger aggregates can be crushed in a variety of ways after being screened out, reducing the number of cycles, extending the life of the equipment, and improving the aggregate crushing effect.

[0004] During use, the device uses a slide to screen the crushed large aggregates, pushes them to the surface of the conveyor belt, and sends them back to the hopper through the transmission pipe for re-crushing.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The utility model provides Figures 1 to 3The aggregate crushing device for premixed mortar shown in the figure includes a screening box 1, a screening module is arranged inside the screening box 1, and the screening module includes a partition 11, a mud chamber 12, a small aggregate chamber 13, a large aggregate chamber 14, a screening plate 2, a fine screening mesh 21, a standard screening mesh 22, a vibration spring 23 and a vibration motor 24.

A recovery box 15 is fixedly connected to the right side of the screening box 1, and a material delivery pipe 16 is fixedly connected to the inside of the recovery box 15. The upper end of the material delivery pipe 16 is fixedly connected to the side wall of the crushing box 4, and a driving motor 17 is fixedly installed on the lower end of the material delivery pipe 16. A water pump 3 is fixedly installed on the left side of the screening box 1, and the water outlet end of the water pump 3 is fixedly connected to a water delivery pipe 31. The side of the water delivery pipe 31 is fixedly connected with a first nozzle 32 and a second nozzle 33. The first nozzle 32 is fixed on the left surface of the screening box 1, and the second nozzle 33 is fixed on the left surface of the crushing box 4.

[0032] The solid waste is put into the crushing box 4. At this time, the motor cooperates with the two sets of transmission gears 43 to drive the two sets of transmission shafts 41 to rotate. The two sets of transmission shafts 41 drive the crushing teeth 42 on both sides to rotate in opposite directions, crushing the solid waste. The crushed waste residue falls onto the surface of the screening plate 2. At this time, the vibration motor 24 drives the screening plate 2 to vibrate, thereby screening the waste residue on its surface. The powdery waste residue passes through the fine screening mesh 21 and falls into the mud chamber 12. The waste residue that can be used for mortar production passes through the standard screening mesh 22 and falls into the small aggregate chamber 13. Then, the larger waste residue slides through the screening plate 2 into the large aggregate chamber 14 on the right, and is transported to the crushing box 4 through the feeding pipe 16 for further crushing. This facilitates the rapid screening of waste materials of various sizes, improves the waste screening accuracy, and avoids the re-crushing of usable waste residue, thereby improving the crushing efficiency of the equipment.

[0033] During the crushing and screening process, the water pump 3 delivers water through the water pipe 31 to the interior of the first nozzle 32 and the second nozzle 33. The first nozzle 32 sprays water onto the surface of the screening plate 2, cleaning the waste residue on the surface of the screening plate 2 and quickly flushing the dust and small particles in the waste residue into the mud chamber 12. The second nozzle 33 sprays water into the crushing box 4, preventing dust from drifting outward during the crushing process and improving the cleanliness of the environment.

The screening fine mesh 21 is located on the upper side of the mud chamber 12, and the screening standard mesh 22 is located on the upper side of the small aggregate chamber 13.

[0035] Specifically, the screening plate 2 is arranged in an inclined shape, and the vibration motor 24 drives the screening plate 2 to vibrate, and the crushed waste residue will fall onto the surface of the screening fine mesh 21. At this time, under the vibration of the screening plate 2, combined with the flushing of the water flow, the powder and smaller waste residue in the waste residue pass through the screening fine mesh 21 and fall into the interior of the mud chamber 12. At this time, the waste residue will slide to the right with the vibrating screening plate 2. During the sliding process, the slag that can be used for production in the waste residue passes through the screening standard mesh 22 and falls into the temporal part of the small aggregate chamber 13, while the larger aggregate will continue to slide to the right and fall into the interior of the large aggregate chamber 14, and then slide into the interior of the recovery box 15 through the large aggregate chamber 14. At this time, the driving motor 17 drives the dragon blade inside the feed pipe 16 to lift the large-particle waste residue to the interior of the crushing box 4, and crush the large-particle waste residue again, so that the equipment can continuously screen the waste residue during the crushing process, further improving the crushing efficiency of the equipment.

[0036] The working principle of the utility model is as follows: the vibration motor 24 cooperates with the vibration spring 23 to drive the screening plate 2 to vibrate, and the second nozzle 33 flushes the waste residue, quickly classifies and screens the waste residue, and avoids the usable waste residue from being crushed again. At the same time, the waste residue can be screened during the crushing process, and the large-particle waste residue can be transported to the inside of the crushing box 4 through the feeding pipe 16 for re-crushing, effectively improving the crushing efficiency of the equipment.
