Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garbage treatment, in particular to a garbage classification and pre-treatment device before landfilling. Background Art
[0002] Landfill remains the primary method for disposing of domestic waste in most Chinese cities, accounting for 85% of municipal solid waste. Pre-sorting waste is necessary to avoid mixing metal, household, and plastic waste, which can lead to insufficient recycling and compromise landfill quality.
[0003] In our daily lives, the garbage that is transported to garbage disposal plants has often been pre-sorted by the staff at various garbage disposal points. Large metal objects and large paper boxes are picked out, while some small metal objects cannot be found and are then sent directly to the garbage disposal plants, resulting in a waste of resources. Utility Model Content
[0004] The purpose of the utility model is to provide a garbage classification and pre-processing device before landfilling to solve the above-mentioned shortcomings in the prior art.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pre-landfill classification and pretreatment equipment for garbage, comprising: an air duct, a loading platform fixedly installed inside the air duct, an inclined plate provided above the loading platform, a fan provided above the inclined plate, an electromagnet fixedly installed on the back of the inclined plate, a push plate slidingly provided between the inclined plate and the loading platform, a push rod fixedly connected to the push plate, a second partition fixedly connected inside the air duct, a wedge fixedly connected to the bottom of the second partition by a spring, a pressure rod fixedly connected to the top of the wedge, a trigger switch located directly above the pressure rod provided on the electromagnet, and when the push rod squeezes the wedge, the pressure rod squeezes the trigger switch so that the electromagnet is energized to generate magnetic force.
[0006] Furthermore, two vertical rods are fixedly connected to the top of the wedge block, and the two vertical rods and the pressure rod all pass through the second partition plate.
[0007] Furthermore, a first partition is fixedly connected to the inner wall of the air duct, an electric push rod is fixedly installed on the first partition, and a movable end of the electric push rod is fixedly connected to the push plate.
[0008] Furthermore, a first conveyor belt is provided on a side of the loading platform away from the air duct.
[0009] Furthermore, a second conveyor belt and a third conveyor belt are sequentially arranged in the air duct.
[0010] Furthermore, a third partition is fixedly connected to one side of the third conveyor belt.
[0011] Furthermore, a feed port is provided on the air duct, and the top of the inclined plate is located below the feed port.
[0012] In the above technical solution, the utility model provides a waste classification and pre-treatment equipment before landfill, which has the following beneficial effects:
[0013] The utility model guides the garbage into the air duct along the inclined plate. Under the action of the strong airflow generated by the fan, the garbage with lower density is blown to a farther position, while the material with higher density slides along the inclined plate. Under the action of the magnetic force of the electromagnet, the metal objects are magnetically attracted to the inclined plate, and the push plate can push the garbage with higher density on the loading platform away from the loading platform. At this time, the electromagnet loses its magnetic force, and the metal objects attracted on the inclined plate fall off. Finally, when the push plate is pulled back, the metal objects are brought back into the metal object accumulation bin, thereby realizing the separation of metal objects and garbage of different densities, which is not only beneficial to resource recovery, but also improves the quality of garbage landfill treatment.
[0014] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0023] See also Figures 1 to 3 A garbage classification and pre-treatment equipment before landfill, comprising: an air duct 1, a loading platform 2 is fixedly installed inside the air duct 1, an inclined plate 13 is arranged above the loading platform 2, the inclined plate 13 is fixedly connected to the inner wall of the air duct 1, a fan 3 is arranged above the inclined plate 13, the fan 3 is installed on the air duct 1, an electromagnet 7 is fixedly installed on the back of the inclined plate 13, a push plate 102 is slidingly arranged between the inclined plate 13 and the loading platform 2, the push plate 102 slides in the horizontal direction, a push rod 101 is fixedly connected to the push plate 102, and the push rod 101 is arranged vertically upward, the air duct 1 is fixedly connected to a second partition 15, which is located between the push plate 102 and the electromagnet 7. The bottom of the second partition 15 is fixedly connected to a wedge block 8 via a spring 9. One end of the spring 9 is fixedly connected to the top of the wedge block 8, and the other end of the spring 9 is fixedly connected to the bottom of the second partition 15. The top of the wedge block 8 is fixedly connected to a pressure rod 82. The electromagnet 7 is provided with a trigger switch 71 located directly above the pressure rod 82. When the push rod 101 squeezes the wedge block 8, the pressure rod 82 squeezes the trigger switch 71, causing the electromagnet 7 to be energized to generate magnetic force.
[0024] Specifically, the present invention guides the garbage into the air duct 1 along the inclined plate 13. Under the action of the strong airflow generated by the fan 3, the garbage with lower density is blown to a farther position, while the material with higher density slides along the inclined plate 13. Under the magnetic force of the electromagnet 7, the metal objects are magnetically attracted to the inclined plate 13, and the push plate 102 can push the garbage with higher density on the loading platform 2 away from the loading platform 2. At this time, the electromagnet 7 loses its magnetic force, and the metal objects adsorbed on the inclined plate 13 fall off. Finally, when the push plate 102 is pulled back, it is brought back to the metal object accumulation bin 14, thereby realizing the separation of metal objects and the separation of garbage with different densities, which is not only beneficial to resource recovery, but also improves the quality of landfill treatment.
[0025] Furthermore, two vertical rods 81 are fixedly connected to the top of the wedge block 8 , and the two vertical rods 81 and the pressure rod 82 all pass through the second partition plate 15 .
[0026] Specifically, when the wedge block 8 slides in the vertical direction, the two vertical rods 81 play a guiding role, and the pressure rod 82 plays a role in squeezing the trigger switch 71 so that the electromagnet 7 is energized to generate magnetic force.
[0027] Furthermore, a first partition plate 11 is fixedly connected to the inner wall of the air duct 1 , an electric push rod 10 is fixedly mounted on the first partition plate 11 , and a movable end of the electric push rod 10 is fixedly connected to a push plate 102 .
[0028] Specifically, the push plate 102 is driven to reciprocate by the electric push rod 10, referring to Figure 1 and Figure 3 When the electric push rod 10 drives the push plate 102 to move to the right, the push plate 102 pushes the high-density garbage on the top of the loading platform 2 away from the loading platform 2. When the garbage on the loading platform 2 is about to be completely pushed away, the push rod 101 is no longer in contact with the wedge block 8. Under the action of the elastic force of the spring 9 and the weight of the wedge block 8 itself, the wedge block 8 slides downward, causing the pressure rod 82 to disengage from the trigger switch 71, and the electromagnet 7 is powered off, causing the electromagnet 7 to lose its magnetic force. The metal garbage originally adsorbed on the inclined plate 13 slides along the inclined surface of the inclined plate 13 to the top of the loading platform 2. When the push plate 102 is brought back by the electric push rod 10, the garbage on the top of the loading platform 2 is brought back to the metal object accumulation bin 14, completing the separation between the metal garbage and the rest of the high-density garbage.
[0029] Furthermore, a first conveyor belt 4 is provided on a side of the loading platform 2 away from the air duct 1 .
[0030] Specifically, refer to Figure 1 and Figure 3 When the push plate 102 moves to the right, the garbage on the top of the loading platform 2 is pushed away from the loading platform 2 and falls onto the first conveyor belt 4 to be transported away.
[0031] Furthermore, a second conveyor belt 5 and a third conveyor belt 6 are sequentially arranged in the air duct 1 .
[0032] Specifically, refer to Figure 1 and Figure 2 The strong airflow generated by the fan 3 blows the garbage away. The higher the density of the garbage, the closer it is to the air outlet of the fan 3, and the lower the density of the garbage, the farther away from the air outlet. This makes the density of the garbage falling on the second conveyor belt 5 and the third conveyor belt 6 different, thereby realizing garbage classification and transporting them out of the air duct 1 separately.
[0033] Furthermore, a third partition plate 61 is fixedly connected to one side of the third conveyor belt 6 .
[0034] Specifically, refer to Figure 2 The third partition plate 61 is fixedly connected to the third conveyor belt 6 at the farthest end from the fan 3 to prevent the garbage from flying farther, ensuring that the garbage will not be blown everywhere, thereby facilitating cleaning of the air duct 1.
[0035] Furthermore, a feed port 12 is provided on the air duct 1 , and the top of the inclined plate 13 is located below the feed port 12 .
[0036] Specifically, refer to Figure 1 and Figure 2 The feed port 12 is the feed port of the air duct 1, and the inclined plate 13 is arranged below the feed port 12 to facilitate the collection of metal waste.
[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
