[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] In addition, in the application, the terms "first", "second" and other similar terms do not imply any order, quantity and importance, but are only used to distinguish different elements, and the terms "up", "down", "left", "right" and other similar terms are only the positional relationship in the drawings.

[0028] The common way of recycling mixed material waste is to crush the whole waste, and then screen to complete separation and recycling. However, after crushing, different types of materials will inevitably stick to each other, and when recycling, the same material box will contain multiple materials.

[0029] In this application, the method adopted is to separate the materials according to their density and weight after crushing and separation, and then to screen the separated materials a second time to screen out the solid waste that is not completely separated. The solid waste that is not completely separated is then crushed again so that all the solid waste is completely separated.

[0030] like Figure 1 As shown in the figure, this application provides a solid waste recycling device, including: a filter tank 1, a rinsing chamber 2, a water separation mechanism 3, a primary discharge plate 4, a secondary discharge plate 5, a water inlet 6, a crusher 7, a recycling channel 8, and a secondary screening mechanism 9. The filter tank 1 serves as the base of the entire device and also as a water storage tank. Filter cotton is provided in the middle of the filter tank 1. During water separation, a water pump draws clean water from below the filter cotton, and the water after water separation flows back into the filter tank 1 for filtration. The rinsing chamber 2 is located above the filter tank 1. The crusher 7 is installed on the washing chamber 2. After being crushed by the crusher 7, the waste falls into the washing chamber 2. One end of the water separation mechanism 3 is located inside the washing chamber 2. The waste crushed by the crusher 7 falls onto the water separation mechanism 3. At the same time, a water inlet 6 is provided at the top of the washing chamber 2, through which water is supplied into the washing chamber 2. After the water flows into the washing chamber 2, it falls onto the water separation mechanism 3. The conveying direction of the water separation mechanism 3 is opposite to the direction of the water flow. The waste is screened by the water flow. The waste with higher density remains on the water separation mechanism 3. Waste with lower density is carried away by the water flow; the water separation mechanism 3 has a primary discharge plate 4 and a secondary discharge plate 5 at both ends, both located below the water separation mechanism 3. Correspondingly, the bottom of the rinsing chamber 2 has a downward opening at the primary discharge plate 4; the water separation mechanism 3 carries the denser waste upward against the current, and finally falls into the primary discharge plate 4 due to gravity, while the water flow carries the less dense waste downward with the current, and finally falls into the secondary discharge plate 5 due to gravity; and the water separation mechanism 3 and the secondary discharge plate 5... A secondary screening mechanism 9 is also provided between the primary discharge plates 5. The secondary screening mechanism 9 is used to screen out the mixture of metals and non-metals. One end of the secondary screening mechanism 9 is also provided with a recovery channel 8. The two ends of the recovery channel 8 are connected to the crusher 7 and the secondary screening mechanism 9, respectively. The mixture of metals and non-metals screened out by the secondary screening mechanism 9 falls onto the recovery channel 8. One end of the recovery channel 8 is connected to a reverse conveying power element. Driven by the reverse conveying power element, the mixture falling onto the recovery channel 8 is conveyed into the crusher 7.

[0031] It should be noted that the type of secondary screening mechanism 9 is determined according to the type of metal contained in the waste, if the waste contains magnetic materials such as iron, cobalt, nickel and the like, the secondary screening mechanism 9 is selected as a magnetic separator, if the waste contains diamagnetic or paramagnetic materials such as aluminum, magnesium, lithium, sodium and the like, the secondary screening mechanism 9 is selected as an eddy current separator. Or the secondary screening mechanism 9 contains both a magnetic separator and an eddy current separator.

[0032] On the other hand, the water sorting mechanism 3 at least includes a conveying belt with grooves on the surface, the grooves have a stopping effect on waste with a larger density, and can slow down the fluid flow rate on the surface of the conveying belt.

[0033] On the other hand, for the water sorting mechanism 3, different water flow rates can separate solid waste of different densities or weights, and different types of mixed waste can be separated multiple times by different flow rate devices.

[0034] On the other hand, if the waste is directly separated by a magnetic separator and / or an eddy current separator after being crushed, metal parts with non-metal materials adhered will also be selected. If the water sorting mechanism 3 is used before the magnetic separator and / or the eddy current separator, the metal and non-metal parts can be completely separated. If the plastic part contains a metal insert, due to the smaller density of the plastic, the mixed waste will be carried away by the water flow, and the plastic part containing the metal insert will be selected by the magnetic separator and the eddy current separator.

[0035] In an embodiment of the present application, the first discharge plate 4 and the second discharge plate 5 are both connected with the vibration motor, and the top of the first discharge plate 4 is connected with the flushing bin 2. In this way, the vibration of the vibration motor is transmitted to the first discharge plate 4 and the second discharge plate 5 to drive the waste on the first discharge plate 4 and the second discharge plate 5 to move by vibration. On the other hand, the vibration of the first discharge plate 4 is transmitted to the water sorting mechanism 3 through the flushing bin 2. In this way, the waste can be prevented from adhering to the water sorting mechanism 3.

[0036] In an embodiment of the present application, the water sorting mechanism 3 is provided with a baffle at the other end for guiding the movement of the waste and water flow to the second discharge plate 5.

[0037] As shown in FIG. 1, Figure 2 In an embodiment of the present application, the inside of the flushing bin 2 is provided with a flow distribution plate 21. The flow distribution plate 21 evenly covers the water sorting mechanism 3 with water flow, and reduces the local flow rate when the water flow falls on the water sorting mechanism 3, so as to prevent the selected metal materials from being washed away due to too fast local flow rate.

[0038] As shown in FIG. 1, Figure 3As shown in the embodiment of the present application, the crusher 7 is selected as a double-shaft shearing crusher, which comprises a feeding bin 71, blades 72, movable baffles 73, springs 74, spring clamping seats 75, a plurality of the blades 72 are installed in two groups in the feeding bin 71, the spring clamping seats 75 are installed on the outer wall of the feeding bin 71, a plurality of movable baffles 73 are arranged in the spring clamping seats 75, and the springs 74 are installed at one end of the movable baffles 73, the springs 74 apply force to the movable baffles 73 towards the blades 72, so that one end of the movable baffles 73 is tightly attached to the blades 72, thus avoiding the waste falling from the gap between the blades 72 and the feeding bin 71.
