Description

Technical Field

[0001] This utility model relates to the field of construction solid waste treatment technology, specifically a crushing and processing device for the comprehensive reuse of construction solid waste. Background Technology

[0002] Construction solid waste refers to solid waste generated during the construction, maintenance, and demolition of buildings. It mainly includes waste concrete blocks, waste asphalt concrete blocks, and mortar, concrete, and broken bricks scattered during construction. According to the source, construction solid waste can be divided into five categories: land excavation, road excavation, demolition of old buildings, construction waste, and building material production waste. Among them, waste generated from the demolition of old buildings and construction waste accounts for the vast majority.

[0003] In the process of treating construction solid waste, vertical compound crushers are generally used for crushing. After the material enters from the feed inlet at the top of the equipment, it first falls into a high-speed rotating throwing disc (or impeller), and is thrown against the impact plate on the inner wall of the cylinder by centrifugal force, which, together with the crushing hammer, achieves crushing. However, the crushed material contains a lot of iron impurities, and the heavy metals produced by the corrosion of scrap iron can easily cause leakage and secondary pollution. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a crushing and processing device for the comprehensive reuse of construction solid waste, thereby solving the problem of iron removal during the crushing of construction solid waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A crushing and processing device for comprehensive recycling of construction solid waste, comprising: Grinding box; Except for the iron box, it is installed at the bottom of the crushing box and is connected to the discharge port of the crushing box; Drive unit one is installed on one side of the iron removal box; The rotating discs are a set, which are movably installed on both sides inside the iron removal box via a rotating shaft, and the drive device can drive the set of rotating discs to rotate. Several magnetic rods are evenly installed between the rotating disks; The pneumatic actuator is installed on the other side of the iron removal box; The push rod is mounted on the push end of the pneumatic actuator; The cleaning disc is mounted on the front end of the push rod via a rotating bearing and is movably mounted on several magnetic rods.

[0006] Furthermore, the pulverizing chamber is equipped with a pulverizing mechanism; the pulverizing mechanism includes... A cone-shaped feeding hopper is inserted into the top of the crushing box; Drive unit two is located on one side of the crushing chamber; The rotating shaft is movably inserted inside the crushing chamber; Several crushing hammers are evenly installed on the upper end of the rotating shaft; Several annular grinding rollers are evenly installed at the lower end of the rotating shaft. The crushing mechanism crushes and grinds the material, facilitating subsequent iron removal.

[0007] Furthermore, the second drive device is rotatably connected to the rotating shaft via a transmission belt, and the conical feeding hopper has a notch corresponding to the transmission belt.

[0008] Furthermore, the inner wall of the crushing chamber is equipped with impact liners corresponding to several crushing hammers. The material reciprocates between the crushing hammers and the impact liners to achieve thorough crushing. The inner wall of the crushing chamber has several annular grooves corresponding to several annular grinding rollers to achieve crushing and grinding of the crushed material.

[0009] Furthermore, the cleaning disc has several circular holes evenly spaced on it, corresponding to the magnetic rod, to facilitate the cleaning of iron impurities on the magnetic rod.

[0010] Furthermore, a three-way distributor is installed at the bottom outlet of the iron removal box. The three-way distributor is driven by a hydraulic rod, which facilitates the classification and discharge of materials and iron impurities.

[0011] This utility model provides a crushing and processing device for the comprehensive reuse of construction solid waste, which has the following beneficial effects: after the construction solid waste is crushed in the crushing box, the material falls into the iron removal box. The driving device drives several magnetic rods to rotate, adsorbing iron impurities in the material. The cleaning disc can automatically clean the iron impurities on the magnetic rods, realizing the recycling of resources and reducing pollution and solid waste pressure. Attached Figure Description
