Description

Technical Field

[0001] This utility model relates to the field of pulping technology, and in particular to a high-speed pulping machine that integrates crushing and grinding. Background Technology

[0002] With the ongoing construction, accelerated urban renewal, and road renovation and expansion across my country, a large amount of construction waste is generated. Statistics show that 500 to 600 tons of construction waste are produced for every 10,000 square meters of building construction. However, the current method of disposal for construction waste is still primarily landfill, resulting in extremely low utilization rates. Landfilling not only occupies land resources but also severely restricts urban development.

[0003] Chinese patent CN 117945785 A discloses a lightweight ceramsite for building materials made from construction waste and its molding apparatus and method. The ceramsite is made from raw materials including construction waste, river and lake silt, bauxite tailings, Bayer red mud, and pore-forming materials. The molding apparatus includes an extrusion assembly and a matching perforation plate. The extrusion assembly has two sets of intersecting blades forming a quadrilateral grid of extrusion dies. The perforation plate has multiple conical needles arranged and installed corresponding to the extrusion dies. The preparation method involves multi-stage screening of construction waste, drying, crushing, and ball milling with other raw materials, adding water, aging, extruding and granulating, drying, and then pre-firing and calcining. The ceramsite of this invention uses all-solid-waste raw materials, achieving full utilization of solid waste resources and improving the bonding strength between the ceramsite and cement paste in concrete. The apparatus effectively controls the shape and structure of the lightweight ceramsite, improving the preparation efficiency. The preparation process of this invention is simple and easy to implement.

[0004] When reusing construction waste, it is necessary to crush and grind the solid waste. However, the hardness of various materials in construction waste varies, and existing grinding and crushing equipment cannot be applied to solid waste of various hardnesses, resulting in mediocre crushing and grinding effects. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a high-speed pulping machine that integrates crushing and grinding.

[0006] To achieve the above objectives, a high-speed pulping machine integrating crushing and grinding includes a cylinder. An inlet and an outlet are provided on the outer side of the cylinder. A rotary drive device is provided on one side of the cylinder. The drive end of the rotary drive device is located inside the cylinder and is connected to a crushing and grinding mechanism. The crushing and grinding mechanism includes a rotary shaft connected to the drive end of the rotary drive device, a rotary disk installed on the outer side of the rotary shaft, a plurality of crushing blades installed on the outer side of the rotary disk, crushing hammers installed on the outer ends of the crushing blades, a connecting arm installed on the outer side of the rotary shaft, and a grinding structure installed on the outer side of the connecting arm.

[0007] Preferably, there are two rotating disks, and several connecting shafts are horizontally fixedly installed on the two rotating disks, and the crushing blade arm is rotatably installed on the outside of the corresponding connecting shaft.

[0008] Preferably, the breaker hammer head is rotatably mounted on the outside of the breaker arm via a rotating shaft.

[0009] Preferably, the connecting arm is fixedly installed on the outside of the rotating shaft, and the grinding structure includes an arc-shaped continuous beam installed on the outside of the connecting arm, and a plurality of first grinding teeth installed on the outside of the arc-shaped continuous beam.

[0010] Preferably, the inner wall of the cylinder is fitted with fixed grinding teeth that are compatible with the first grinding teeth.

[0011] Preferably, the first grinding tooth, the fixed grinding tooth, and the crushing hammer are all made of alloy.

[0012] Preferably, the feed inlet is located at the top of the cylinder, a water inlet pipe is provided on one side of the feed inlet, and the discharge outlet is located above the side of the cylinder away from the rotary drive device.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through its shredding arms, shredding hammers, and grinding structure, allows for efficient crushing of solid waste materials. When solid waste is fed into the cylinder through the inlet, a rotary drive mechanism rotates the shaft. The shredding hammers crush harder materials within the cylinder, while the shredding arms, without hammers, break softer materials to a smaller size. The grinding structure, abutting against the inner wall of the cylinder, ensures thorough grinding. Compared to existing technologies, this device is suitable for crushing and grinding various soft and hard materials, effectively improving crushing and grinding efficiency.
