Description

Technical Field

[0001] This application relates to the field of solid waste treatment, and particularly to a solid waste recycling device. Background Art

[0002] Industrial solid waste often contains various materials. For example, in construction waste, it may contain multiple types of materials such as wood, metal, and plastic; or during the injection molding process in a factory, waste containing plastic and metal is generated. Various types of materials may be embedded together, making it difficult to separate different types of materials during recycling. For instance, nails may be contained in wood, and plastic connectors may be embedded in metal parts. The usual recycling method is to crush the waste as a whole and then perform screening to complete separation and recycling. However, after crushing, there will inevitably be a situation where different types of materials are still adhered to each other, and a single material box will contain multiple materials during recycling.

When crushing, there is often a situation where the metal and non-metal materials are not completely separated. In the present application, a secondary screening mechanism is also provided, which can screen out the waste that is not completely separated through the secondary screening mechanism and convey it into the crusher for secondary crushing, so as to completely separate various types of waste. And after the separation is completed, the separated waste can be put back into the crusher again, and the water flow rate of the water inlet and the distance between the crushing blades of the crusher can be adjusted to achieve re-separation.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0018] In addition, in the application, terms such as "first", "second" and other similar words do not intend to imply any order, quantity and importance, but are only used to distinguish different elements. Terms such as "upper", "lower", "left", "right" and other similar words are only positional relationships in the drawings.

[0019] The common method for recycling mixed material waste is to perform crushing treatment on the whole waste, and then perform screening to complete separation and recycling. However, after crushing, it is inevitable that there will still be a situation where different types of materials are adhered to each other. During recycling, a single material box will contain multiple materials.

[0020] In the present application, the adopted method is to separate the materials according to the density and weight of the materials after crushing and separation, and then perform secondary screening on the separated materials to screen out the solid waste that has not been completely separated, and perform re-crushing on the solid waste that has not been completely separated, so as to completely separate all the solid waste.

[0021] Such as Figure 1As shown in the figure, an embodiment of the present application provides a solid waste recycling device, including: a filtration tank 1, a flushing bin 2, a water separation mechanism 3, a primary discharge plate 4, a secondary discharge plate 5, a water inlet 6, a crusher 7, a recovery channel 8, and a secondary screening mechanism 9. The filtration tank 1 serves as the base of the entire device and also as a water storage tank. A filter cotton is provided in the middle of the filtration tank 1. When performing water separation, a water pump extracts clean water from below the filter cotton. The water after water separation flows back into the filtration tank 1 and is filtered; The flushing bin 2 is arranged above the filtration tank 1, and the crusher 7 is installed on the flushing bin 2. After the waste is crushed by the crusher 7, it falls into the flushing bin 2; One end of the water separation mechanism 3 is located inside the flushing bin 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 flushing bin 2, and water is conveyed into the flushing bin 2 through the water inlet 6; After the water flows into the flushing bin 2, it falls onto the water separation mechanism 3, and 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 a greater density stays on the water separation mechanism 3, and the waste with a smaller density is carried away by the water flow; At both ends of the water separation mechanism 3, a primary discharge plate 4 and a secondary discharge plate 5 are respectively provided. Both the primary discharge plate 4 and the secondary discharge plate 5 are located below the water separation mechanism 3. Correspondingly, a downward opening is provided at the bottom of the flushing bin 2 corresponding to the primary discharge plate 4; The water separation mechanism 3 drives the waste with a greater density to flow upstream, and finally falls into the primary discharge plate 4 due to the action of gravity. The water flow drives the waste with a smaller density to flow downstream, and finally falls into the secondary discharge plate 5 due to the action of gravity; A secondary screening mechanism 9 is also provided between the water separation mechanism 3 and the secondary discharge plate 5. The secondary screening mechanism 9 is used to screen out the mixture of metal and non-metal, and one end of the secondary screening mechanism 9 is also provided with a recovery channel 8. Among them, both ends of the recovery channel 8 are respectively connected to the crusher 7 and the secondary screening mechanism 9. The mixture of metal and non-metal screened out by the secondary screening mechanism 9 falls onto the recovery channel 8, and 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.

[0022] It should be noted that the type of the secondary screening mechanism 9 is determined according to the types of metals contained in the waste. If the waste contains magnetic materials, such as iron, cobalt, nickel and other materials, 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 other materials, the secondary screening mechanism 9 is selected as an eddy current separator. Or the secondary screening mechanism 9 simultaneously includes a magnetic separator and an eddy current separator.

[0023] On the other hand, the water separation mechanism 3 at least includes a conveyor belt with grooves on its surface. The grooves have a stopping effect on the waste with a greater density and can slow down the fluid flow rate on the surface of the conveyor belt.

[0024] On the other hand, for the water separation mechanism 3, different water flow velocities can separate solid wastes of different densities or weights, and different types of mixed wastes can be separated multiple times by devices with different flow velocities.

[0025] On the other hand, if the magnetic separator and / or eddy current separator are directly used for separation and screening after the waste is crushed, metal parts adhered with non-metallic materials will also be selected. However, if the water separation mechanism 3 is used for separation before the magnetic separator and / or eddy current separator, the metal and non-metal parts can be completely separated. If the plastic parts contain metal inserts, due to the relatively low density of the plastic, the mixed waste will be carried away by the water flow, while the plastic parts containing metal inserts will be selected by the magnetic separator and eddy current separator.

[0026] In an embodiment of the present application, both the first-stage discharge plate 4 and the second-stage discharge plate 5 are connected to the vibration motor, and the top of the first-stage discharge plate 4 is connected to the flushing bin 2. In this way, the vibration of the vibration motor is transmitted to the first-stage discharge plate 4 and the second-stage discharge plate 5, and the waste on the first-stage discharge plate 4 and the second-stage discharge plate 5 is driven to move through vibration. On the other hand, the vibration of the first-stage discharge plate 4 will be transmitted to the water separation mechanism 3 through the flushing bin 2, so that the adhesion of waste to the water separation mechanism 3 can be avoided.

[0027] In an embodiment of the present application, a baffle is provided at the other end of the water separation mechanism 3 for guiding the waste and water flow to move onto the second-stage discharge plate 5.

[0028] As Figure 2 shown, in an embodiment of the present application, a flow dividing plate 21 is provided inside the flushing bin 2. The function of the flow dividing plate 21 is to make the water flow evenly cover the water separation mechanism 3, and reduce the local flow velocity when the water flow falls onto the water separation mechanism 3, so as to avoid the washed-out metal materials being washed away due to too fast local flow velocity.

[0029] As Figure 3 shown, in an embodiment of the present application, the crusher 7 is selected as a double-shaft shear crusher. The crusher 7 includes a feed bin 71, blades 72, movable baffles 73, springs 74, and spring holders 75. The plurality of blades 72 are divided into two groups and installed in the feed bin 71. A spring holder 75 is installed on the outer wall of the feed bin 71. A plurality of linearly movable movable baffles 73 are provided in the spring holder 75, and a spring 74 is installed at one end of the movable baffle 73. The spring 74 applies a force to the movable baffle 73 towards the blades 72, so that one end of the movable baffle 73 is closely attached to the blades 72, thus preventing waste from falling through the gap between the blades 72 and the feed bin 71.

[0030] In an embodiment of the present application, the reverse conveying power element is an air pump, as Figure 1As shown in the figure, a blowing port 10 is provided at one end of the recovery channel 8. The blowing port 10 is connected to an air pump. Driven by the high-pressure air flow blown out from the blowing port 10, the mixture moves along the recovery channel 8 and finally returns to the crusher 7 for secondary crushing.

[0031] As Figure 4 shown, in an embodiment of the present application, the reverse conveying power element is a vibration mechanism 11, and the recovery channel 8 is a vibrating disk connected to the vibration mechanism 11. Among them, the vibration mechanism 11 includes a vibration motor 111, a vibration base 112, a support spring plate 113, a transmission plate 114, and a transmission rod 115. The recovery channel 8 is spiral. The vibration motor 111 and the vibration base 112 are both fixedly installed on the filtration tank 1. The middle of the transmission plate 114 is connected to the output shaft of the vibration motor 111. A number of support spring plates 113 are arranged on the vibration base 112 at equal circumferential intervals. The top of the support spring plate 113 is fixedly connected to the transmission plate 114. The top view plane of the transmission plate 114 is arc-shaped. A number of transmission rods 115 are fixedly installed on the top of the transmission plate 114. The top of the transmission rod 115 is fixedly connected to the recovery channel 8.

[0032] As Figure 1 shown, in an embodiment of the present application, a number of support columns are provided between the filtration tank 1 and the flushing bin 2 and between the filtration tank 1 and the water separation mechanism 3 to support the flushing bin 2 and the water separation mechanism 3. On the other hand, since the vibration motor 111 is installed on the filtration tank 1, the vibration generated by the vibration motor 111 can be transmitted to the flushing bin 2, the water separation mechanism 3, the first discharge plate 4, and the second discharge plate 5 through the filtration tank 1 and the support columns. In this way, the "driving the waste on the first discharge plate 4 and the second discharge plate 5 to move through vibration" and the "avoiding the waste from sticking to the water separation mechanism 3 through vibration" described above can be realized.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
