Technical Field

[0001] This utility model belongs to the field of metal waste application technology, specifically relating to metal waste crushing equipment. Background Technology

[0002] Waste and scrap generated during the processing of metal products are usually melted down and recycled for reuse, which can reduce the economic cost of production and manufacturing.

[0003] To achieve better and faster melting of scrap and slag, the usual practice is to crush them. This allows for faster melting of smaller pieces. However, impurities inevitably get mixed in during the transportation of scrap and slag. If they are melted directly in a smelting furnace, these impurities will be mixed into the molten metal, which can seriously affect the quality of the finished metal products. Therefore, it is necessary to remove impurities from the scrap and slag.

[0004] Therefore, based on the above problems, this utility model provides a metal waste crushing equipment. Utility Model Content

[0024] The upper horizontal housing 101 is equipped with a horizontal rotating shaft 118 that passes through the upper horizontal housing 101 and the flange bearing seat 115 at both ends.

[0025] Several crushing blades 119 are installed on the horizontal rotating shaft 118.

[0026] One end of the horizontal rotating shaft 118 is connected to the coupling 117;

[0027] Among them, the power motor 116 is connected to the PLC controller 120.

[0028] The working principle is as follows:

[0029] (1) The PLC controller 120 starts the power motor 116 to rotate. At this time, the power motor 116 drives the horizontal rotating shaft 118 through the coupling 117 to drive several crushing blades 119 to rotate rapidly.

[0030] (2) The scrap and waste material and the scrap belt are fed into the feed port 102. At this time, several crushing blades 119 crush the scrap and waste material and the scrap belt, and then enter the horizontal box 100 through the discharge port 113 and are discharged from the discharge port 104.

[0031] In addition, the material discharge port 113 is preferably designed as a trumpet-shaped structure, which can achieve rapid material discharge and prevent material accumulation.

[0034] The first explosion-proof solenoid valve 109 and the second explosion-proof solenoid valve 112 are respectively connected to the PLC controller 120.

[0035] The working principle is as follows: (1) The high-temperature flue gas inlet pipe 108 and the high-temperature flue gas outlet pipe 111 are respectively connected to the kiln tail gas branch outlet and the tail gas treatment device (not shown in the figure, which does not affect the disclosure of the technical solution of this application); (2) After feeding, the sealing cover 103 is placed on the feeding port 102; (3) During operation, the manual valve 106 is closed, the PLC controller 120 controls the first explosion-proof solenoid valve 109, the second explosion-proof solenoid valve 112 to open, and the power motor 116 is started; (4) When discharging, the manual valve 106 is opened, the PLC controller 120 controls the first explosion-proof solenoid valve 109, the second explosion-proof solenoid valve 112 to close, and the power motor 116 is stopped.

The PLC controller 120 performs corresponding control according to the preset temperature range. When the temperature exceeds the preset temperature value, the PLC controller 120 controls the first explosion-proof solenoid valve 109 to close.

[0040] In addition, the preferred metal waste crushing equipment also includes a sloped debris guide section 122 disposed in the horizontal box 100, which enables the rapid discharge of crushed debris and waste materials.
