[0026] See Figure 1 - Figure 2 As shown, the aggregate waste and raw material mixing device in this embodiment includes an aggregate crushing component 1, a magnetic screening component 2, a screened material metering and conveying component 63, a raw material metering and conveying component 64, and a mixer 5. The aggregate crushing component 1 has a discharge port 11, and the discharge port 11 is connected to the magnetic screening component 2. The magnetic material component is provided with a coarse material outlet 21 and a fine material outlet 22. The coarse material outlet 21 is connected to the aggregate crushing component 1 through a conveying component 6. The fine material outlet 22 is connected to the screened material metering and conveying component 63. The screened material metering and conveying component 63 and the raw material metering and conveying component 64 are respectively connected to the mixer 5 for respectively conveying the screened aggregate and raw material to the mixer 5.
[0027] This embodiment has a simple structure and a reasonable design. After crushing, screening, and magnetically separating metal substances from the aggregate, it is then mixed with the raw material to achieve a better batching effect.
[0028] In this embodiment, the conveying component 6 can be specifically set as a hoist.
[0029] Specifically, during use, the aggregate waste first enters the aggregate crushing component 1 and is crushed into particles of appropriate size through mechanical crushing. The crushed aggregate is discharged from the discharge port 11 and enters the magnetic screening component 2. This component uses the magnetic principle to separate magnetic substances such as iron impurities in the aggregate. The screened aggregate is divided into two parts: coarse material and fine material. The coarse material returns to the aggregate crushing component 1 through the conveying component 6 for re-crushing. The fine material is precisely metered in the screened material metering and conveying component 63 and is conveyed to the mixer 5 according to the preset ratio requirements. At the same time, the raw material metering and conveying component 64 is responsible for precisely metering the raw material according to the predetermined ratio and amount and conveying it to the mixer 5. In the mixer 5, the precisely metered aggregate waste and raw material are fully mixed to form a mixed material that meets the requirements. Here, the mixer 5 can specifically adopt various mixing methods such as stirring and tumbling to ensure uniform mixing. The mixed material can be directly put into the raw material finished product warehouse.
[0030] In some embodiments, the aggregate crushing component 1 is set as an impact crusher.
[0031] In this embodiment, an impact crusher is specifically used for crushing the aggregate waste. It not only has a good crushing effect but is also efficient and low-consumption, and can better meet the crushing needs.
[0032] In some embodiments, the magnetic screening component 2 is provided with a screening frame 23 and a plurality of screening blocking rods 24. The screening frame 23 is in an open shape. The coarse material outlet 21 is arranged on the side surface of the screening frame 23, and the fine material outlet 22 is arranged at the bottom end of the screening frame 23. The plurality of screening blocking rods 24 are arranged at intervals in the screening frame 23 and are arranged at an inclined angle, and a magnet member 25 is arranged in the screening blocking rod 24.
[0033] Specifically, the lower end of the screening blocking rod 24 is connected to the bottom side surface of the coarse material outlet 21.
[0034] In this embodiment, by adopting the screening frame 23 and installing a plurality of magnetic screening blocking rods 24 at intervals and obliquely in the screening frame 23, during screening, the magnet member 25 arranged in the screening blocking rod 24 can effectively adsorb and separate iron impurities in the material. Due to the strong magnetism of the magnet, even very tiny ferromagnetic particles can be effectively captured, thereby improving the screening accuracy and efficiency. At the same time, the screening blocking rods 24 are arranged at an inclined angle, which helps the material to fully contact with the magnet member 25 during the flowing process, increasing the chance of the iron impurities being adsorbed and further improving the screening effect. Moreover, the screening frame 23 in this embodiment is designed in an open shape, which is convenient for the smooth entry and discharge of the material, reducing the risk of blockage. After screening, the iron impurities adsorbed on the magnet member 25 can be removed through a simple cleaning operation, which is convenient and fast.
[0035] In some embodiments, the screened material metering and conveying component 63 and the raw material metering and conveying component 64 are respectively provided with a storage tank 41, a metering structure 42 and a single-tube conveyor 43. The bottom end of the storage tank 41 is provided with a discharge pipe. The metering structure 42 is arranged on the discharge pipe, and the single-tube conveyor 43 is connected to the discharge pipe.
[0036] In this embodiment, by arranging the metering structure 42 on the discharge pipe, accurate metering of the raw material can be realized and material metering can be carried out. Through the combined use of the storage tank 41, the metering structure 42 and the single-tube conveyor 43, the storage, metering and conveying processes of the raw material are smooth and efficient. At the same time, the closed design of the single-tube conveyor 43 also helps to reduce dust and noise pollution and achieve a better metering and conveying effect.
[0037] In some embodiments, an electromagnet 61 is arranged on the conveying component 6.
[0038] In this embodiment, by arranging the electromagnet 61, the primary coarse material is further screened to prevent it from being brought in and repeatedly crushed, increasing energy consumption.
[0039] In some embodiments, the mixer 5 is a horizontal mixer 5.
[0040] In this embodiment, a horizontal mixer 5 is used for mixing. Since the fine materials of the crushed aggregate waste, although the coarse materials with large particle sizes are screened out, the fine materials still have a certain range of particle sizes. Therefore, by using the horizontal mixer 5, better mixing effects can be achieved for raw materials and aggregates with different particle sizes, densities and viscosities.
[0041] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
