Description

Technical Field

[0001] This utility model relates to the field of air separator technology, and in particular to an air separator for municipal solid waste treatment. Background Technology

[0002] The air separator is used to separate household waste according to its weight. It consists of a mounting frame, a centrifugal fan, a conveyor belt assembly, a discharge port, rotating rollers controlled by an external motor, an exhaust pipe, a duct, and a separation hood. When using the air separator, household waste is poured onto conveyor belt one on the mounting frame. Simultaneously, the centrifugal fan is started, causing the blown air to pass through the duct and be discharged into the separation hood. Household waste falls from the end of conveyor belt one. Lighter waste is blown up, passes the rotating roller, and moves to conveyor belt two. Conveyor belt two and conveyor belt one are controlled by their respective motors. Heavier waste, due to gravity, cannot be blown up by the air and falls from the discharge port. A collection box can be installed at the discharge port, thus achieving the separation of household waste according to weight.

[0003] The inventors discovered in their daily work that when using the air separator, because household waste contains a large amount of moisture, paper waste becomes heavier after absorbing water, making it impossible for it to be blown away by the airflow from the exhaust pipe. This may cause heavier waste to fall off, potentially requiring secondary manual screening and affecting processing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that, in actual use, household waste contains a large amount of moisture, and paper waste, after absorbing water, becomes heavier and may not be able to be blown away by the airflow from the exhaust pipe, thus causing heavier waste to fall off and potentially requiring secondary manual screening, which affects processing efficiency. Therefore, this invention proposes an air separator for household waste processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wind separator for municipal solid waste treatment, comprising a mounting frame, a centrifugal fan mounted at the lower end of the mounting frame, a separation hood fixedly connected to the upper end of the mounting frame, a conveyor belt mounted on one side of the mounting frame, an air duct fixedly connected to the output end of the centrifugal fan, an exhaust pipe fixedly connected to the upper end of the mounting frame, the other end of the air duct fixed to the exhaust pipe, a discharge port opened at the upper end of the mounting frame, a rotating roller controlled by an external motor and a second conveyor belt mounted on the inner wall of the separation hood, a drying assembly provided on one side of the mounting frame, the drying assembly comprising a drying cylinder fixedly connected to one side of the mounting frame, a feed hopper fixedly connected to the arc surface of the drying cylinder, a mounting hole opened at the right end of the mounting frame, a mounting hood fixedly connected to the right end of the mounting frame, an electric heating wire mounted on the inner wall of the mounting hood, an air pipe fixedly connected between the mounting hood and the output end of the centrifugal fan, an air inlet opening on the side of the drying cylinder near the mounting hood, and a discharge mechanism provided at the left end of the mounting frame.

[0006] The effect achieved by the above components is as follows: by setting up the drying components, when it is necessary to dry domestic waste, the waste is poured into the drying cylinder through the feeding hopper. Then, the electric heating wire is activated to heat the inside of the mounting cover. Then, the centrifugal fan is activated so that the generated hot air enters the mounting hole through the air pipe and then enters the drying cylinder through the air inlet to dry the waste. After drying, the waste falls onto the conveyor belt through the feeding mechanism and is then sorted. This achieves the effect of minimizing the need for manual secondary screening of paper waste that absorbs water.

[0007] Preferably, an agitator is rotatably connected to the inner wall of the drying cylinder, and a wind turbine is provided on the inner wall of the mounting hole.

[0008] The effect achieved by the above components is that when the air pipe blows towards the wind turbine, it drives the agitator to rotate, thereby turning the garbage and drying it in conjunction with the hot air.

[0009] Preferably, the agitator and the wind turbine are fixed, and the feeding mechanism includes a drawer plate disposed on the inner wall of the drying cylinder.

[0010] The effect achieved by the above components is to pull out the pull plate, allowing the waste to fall into the conveyor belt.

[0011] Preferably, the drawer plate is slidably inserted into the drying cylinder, and the drawer plate passes through the mounting frame.

[0012] The effect achieved by the above components is to control the falling of garbage by controlling the pull-out plate.

[0013] Preferably, a sealing ring is provided between the mounting bracket and the drawer for sealing.

[0014] The effect achieved by the above components is to prevent sewage from flowing out of the mounting frame along the suction plate by setting a sealing ring.

[0015] Preferably, the inner wall of the feed hopper is provided with a blocking assembly, the blocking assembly including baffles rotatably installed on both sides of the inner wall of the feed hopper.

[0016] The effect achieved by the above components is to prevent small debris from being blown out when the agitator and hot air agitate the garbage by setting up baffles.

[0017] Preferably, a spring is fixedly connected to the lower end of the baffle, and the other end of the spring is fixed to the feed hopper.

[0018] The effect achieved by the above components is as follows: when garbage is poured into the baffle, the weight of the garbage causes the baffle to rotate downwards, and after the garbage falls in, the spring drives the baffle to return to its original position.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by setting up a drying component, when household waste needs to be dried, the waste is poured into the drying cylinder through the feeding hopper. Then, the electric heating wire is activated to heat the inside of the mounting cover. Next, the centrifugal fan is activated, so that the generated hot air enters the mounting hole through the air pipe and then enters the drying cylinder through the air inlet to dry the waste. After drying, the waste falls onto the conveyor belt through the feeding mechanism and is then sorted. This achieves the goal of minimizing the need for manual secondary screening of paper waste that absorbs water. It solves the problem that because household waste contains a large amount of moisture, paper waste becomes heavier after absorbing water, making it impossible for it to be blown away by the air discharged from the exhaust pipe. This could cause heavier waste to fall off, potentially requiring manual secondary screening and affecting processing efficiency. Attached Figure Description

[0026] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a wind separator for municipal solid waste treatment includes a mounting frame 1, a centrifugal fan 4 installed at the lower end of the mounting frame 1, a separation hood 5 fixedly connected to the upper end of the mounting frame 1, a conveyor belt 6 installed on one side of the mounting frame 1, an air duct 7 fixedly connected to the output end of the centrifugal fan 4, an exhaust pipe 8 fixedly connected to the upper end of the mounting frame 1, the other end of the air duct 7 being fixed to the exhaust pipe 8, a discharge port 9 opened at the upper end of the mounting frame 1, a rotating roller 10 controlled by an external motor and a conveyor belt 11 installed on the inner wall of the separation hood 5, and a drying assembly 2 provided on one side of the mounting frame 1.

[0027] Reference Figure 2 and Figure 3As shown in this embodiment: the drying assembly 2 includes a drying cylinder 21 fixedly connected to one side of the mounting frame 1. A feed hopper 22 is fixedly connected to the arc surface of the drying cylinder 21. A mounting hole 26 is opened at the right end of the mounting frame 1. A mounting cover 23 is fixedly connected to the right end of the mounting frame 1. An electric heating wire 24 is installed on the inner wall of the mounting cover 23. An air pipe 25 is fixedly connected between the mounting cover 23 and the output end of the centrifugal fan 4. An air inlet 27 is opened on the side of the drying cylinder 21 near the mounting cover 23. A feeding mechanism 28 is provided at the left end of the mounting frame 1. By setting up the drying assembly 2, when it is necessary to dry domestic waste, the waste is poured into the drying cylinder 21 through the feed hopper 22. Then, the electric heating wire 24 is activated to heat the inside of the mounting cover 23. Then, the centrifugal fan 4 is activated so that the generated hot air enters the mounting hole 26 through the air pipe 25 and then enters the drying cylinder 21 through the air inlet 27 to dry the waste. After drying, the waste falls onto the conveyor belt 6 via the feeding mechanism 28, where it is sorted. This helps to minimize the need for manual secondary screening of absorbent paper waste. An agitator 210 is rotatably connected to the inner wall of the drying cylinder 21, and a wind turbine 29 is installed on the inner wall of the mounting hole 26. When the air pipe 25 blows towards the wind turbine 29, it causes the agitator 210 to rotate, thereby turning the waste and drying it with hot air. The agitator 210 and the wind turbine 29 are fixed. The feeding mechanism 28 includes a drawer plate 281 installed on the inner wall of the drying cylinder 21. Pulling out the drawer plate 281 allows the waste to fall onto the conveyor belt 6. The drawer plate 281 is slidably inserted into the drying cylinder 21 and passes through the mounting frame 1. By controlling the puller plate 281 to pull it out, the waste can be controlled to fall. A sealing ring is installed between the mounting frame 1 and the drawer plate 281 to prevent wastewater from flowing out of the mounting frame 1 along the drawer plate 281.

[0028] Reference Figure 4 As shown in this embodiment: the inner wall of the feed hopper 22 is provided with a blocking component 3. The blocking component 3 includes baffles 31 rotatably installed on both sides of the inner wall of the feed hopper 22. By setting the baffles 31, smaller fragments are prevented from floating out when the agitator 210 and hot air agitate the garbage. A spring 32 is fixedly connected to the lower end of the baffle 31. The other end of the spring 32 is fixed to the feed hopper 22. When the garbage is poured into the baffle 31, the weight of the garbage causes the baffle 31 to rotate downward. After the garbage falls in, the spring 32 drives the baffle 31 to return to its original position.

[0029] Working principle:

[0030] When using the air separator, household waste is poured onto conveyor belt 6 on mounting frame 1. Simultaneously, centrifugal fan 4 is started, causing the blown air to pass through duct 7 and exhaust duct 8 at an inclined angle, exiting into separation hood 5. Household waste falls from the end of conveyor belt 6. Lighter waste is blown up, passes through rotating roller 10, and moves to conveyor belt 11. Conveyor belts 6 and 11 are controlled by their respective motors. Heavier waste, due to gravity, cannot be blown up and falls from discharge port 9. A collection box can be installed at discharge port 9 to achieve separation of household waste by weight. When drying is required, the waste is poured into the drying cylinder 21 through feed hopper 22. Then, electric heating wire 24 is activated to heat the inside of mounting hood 23, and then centrifugal fan 4 is started. The blower 4 generates hot air which enters the mounting hole 26 through the air pipe 25 and then enters the drying cylinder 21 through the air inlet 27 to dry the waste. After drying, the waste is pulled out through the pull plate 281 and falls onto the conveyor belt 6 for sorting. This helps to avoid the need for manual secondary screening of paper waste that absorbs water. When the air pipe 25 blows towards the wind turbine 29, it drives the agitator 210 to rotate, thereby turning the waste and drying it with the hot air. By setting a sealing ring, wastewater is prevented from flowing out of the mounting frame 1 along the pull plate 281. By setting a baffle 31, small fragments are prevented from flying out when the agitator 210 turns the waste with the hot air. Due to the weight of the waste, the baffle 31 rotates downward. After the waste falls in, the spring 32 drives the baffle 31 to return to its original position.
