Description

Technical Field

[0001] This utility model relates to the field of waste sorting, and in particular to a horizontal sorting machine with high efficiency. Background Technology

[0002] Waste is typically processed by coarse crushing equipment into a mixture of small solids, lightweight materials, and dust, which is then transported to an air separation chamber to separate small pieces, thin films, and dust.

[0003] Horizontal air classifiers are commonly used sorting equipment. They have a blowing structure at the material discharge end of the upper conveyor to separate heavy materials, thin film materials, and dust materials. However, they have the following drawbacks: First, the air outlets of the blowing structure are located below the conveyor belt of the upper conveyor, and the conveyor belt will obstruct the airflow at the air outlets, thus affecting the material sorting effect. Second, when heavy materials fall to the lower conveyor after being sorted, they are prone to directly colliding with the air outlets, which will affect the service life of the blowing structure. Utility Model Content

[0004] To address one or more of the aforementioned problems, this utility model provides a horizontal sorting machine for high-efficiency sorting.

[0005] According to one aspect of the present invention, a high-efficiency horizontal sorting machine includes a sorting body, a high-pressure blowing assembly, and a flow guiding assembly.

[0006] The sorting machine body includes a casing, a first belt conveyor, a second belt conveyor, and an exhaust pipe. A sorting space is provided inside the casing. The discharge end of the first belt conveyor, the feed end of the second belt conveyor, and the air inlet end of the exhaust pipe are all located in the sorting space.

[0007] The high-pressure blowing assembly includes a first pressurized air duct, a middle air duct, and a second pressurized nozzle. The middle air duct is connected to the first pressurized air duct and the second pressurized nozzle, and the second pressurized nozzle is located in the sorting space. The first pressurized air duct is connected to the air supply system.

[0008] The flow guiding assembly includes a flow guide plate installed on the first belt conveyor. The flow guide plate is located below the discharge end of the first belt conveyor and is used to guide the material discharged from the first belt conveyor at an angle. The air outlet of the second pressurized nozzle is located below the material discharge end of the flow guide plate and the heavy material and light material are separated by blowing air through the air outlet of the second pressurized nozzle.

[0009] In some embodiments, both the first pressurization duct and the second pressurization nozzle are conical.

[0010] In some implementations, protective pads are installed on both sides of the second booster nozzle.

[0011] In some implementations, the distance between the feed end of the guide plate and the conveyor belt of the first belt conveyor is 1 cm.

[0012] In some embodiments, two sets of L-shaped support frames are fixedly connected to the bottom surface of the guide plate, and the sides of the L-shaped support frames abut against the inner wall of the first belt conveyor.

[0013] In some embodiments, each L-shaped support frame is provided with a connecting screw hole, and the first belt conveyor is provided with a through hole and a bolt is provided in the through hole. The L-shaped support frame is installed on the first belt conveyor through the connecting screw hole and the bolt.

[0014] In some implementations, the L-shaped support frame is welded to the first belt conveyor.

[0015] In some implementations, baffles are fixedly connected to both sides of the guide plate.

[0016] In some implementations, the deflector is made of solid steel plate.

[0017] In some embodiments, filter holes are provided on the guide plate, and a low-pressure blowing assembly for blowing air onto the filter holes on the guide plate is provided below the guide plate.

[0018] In some embodiments, the low-pressure blower assembly includes a low-pressure duct with a conical outlet and an exhaust outlet located below the baffle plate.

[0019] In some implementations, the air inlet of the low-pressure duct is fixedly connected to the middle duct.

[0020] In some embodiments, the low-pressure blowing assembly includes a blower, and the air inlet end of the low-pressure air duct is fixedly connected to the air outlet end of the blower.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model tilts the guide plate below the discharge end of the first belt conveyor and guides the material obliquely to the lower area. The outlet of the second pressurized nozzle is directly positioned below the discharge end of the guide plate, avoiding the conveyor belt. The airflow is no longer blocked by the conveyor belt and can directly act on the sliding material. Furthermore, by setting a high-pressure blowing assembly, using a conical first pressurized air pipe and a second pressurized nozzle, the airflow is pressurized twice, resulting in stronger airflow pressure. This allows for precise and efficient separation of heavy and light materials, significantly improving the accuracy and efficiency of material sorting.

[0023] 2. The guide plate can directly block heavy materials falling from the first conveyor belt, preventing them from directly impacting the second pressurizing nozzle. By installing protective pads on both sides of the second pressurizing nozzle, the hard contact between the heavy materials and the nozzle can be converted into a soft contact, further buffering the impact force, greatly reducing the wear of the blowing components, significantly extending the service life of the core components of the equipment, and reducing equipment maintenance costs.

[0024] 3. By setting up a low-pressure blowing assembly and a filter guide plate, the combination of low-pressure blowing and filter guide plate can not only achieve preliminary material sorting, but also accelerate the material flow rate to avoid material jamming, adapting to the air supply conditions and material handling needs of different factories.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0037] Figures 1 to 6 The diagram schematically illustrates a horizontal sorting machine for high-efficiency sorting according to the present invention.

[0038] Example 1

[0039] Please see Figures 1 to 3 As shown, this utility model provides a horizontal sorting machine for high-efficiency sorting, including a sorting machine body 1, a high-pressure blowing assembly 2, and a flow guiding assembly 3.

[0040] The sorting machine body 1 includes a casing 11, a first belt conveyor 12, a second belt conveyor 13, and an exhaust pipe 14. A sorting space is provided inside the casing 11. The unloading end of the first belt conveyor 12, the feeding end of the second belt conveyor 13, and the air inlet end of the exhaust pipe 14 are all located in the sorting space.

[0041] The feeding end of the first belt conveyor 12 and the unloading end of the second belt conveyor 13 are both located outside the housing 11. The first belt conveyor 12 and the second belt conveyor 13 are both composed of a motor, a drive roller, a driven roller, a conveyor belt and a frame.

[0042] The high-pressure blowing assembly 2 includes a first pressurized air duct 21, a middle air duct 22 and a second pressurized nozzle 23. The middle air duct 22 is connected to the first pressurized air duct 21 and the second pressurized nozzle 23, and the second pressurized nozzle 23 is located in the sorting space. The first pressurized air duct 21 is connected to the air supply system.

[0043] The factory usually has a centralized air supply system, which connects the air inlet of the first pressurized air duct 21 to the air supply system. If there is no air supply system, the first pressurized air duct 21 can be connected to the blower end of the fan.

[0044] The flow guiding component 3 includes a flow guiding plate 31 installed on the first belt conveyor 12. The flow guiding plate 31 is located below the discharge end of the first belt conveyor 12 and is used to obliquely guide the material discharged from the first belt conveyor 12. The flow guiding plate 31 is inclined on the first belt conveyor 12. The material unloaded from the conveyor belt of the first belt conveyor 12 will fall at an angle under the guidance of the flow guiding plate 31. The flow guiding plate 31 can also prevent heavy materials in the material from falling directly and colliding with the second pressurizing nozzle 23. The air outlet of the second pressurizing nozzle 23 is located below the discharge end of the flow guiding plate 31, and the heavy and light materials are separated by blowing air through the air outlet of the second pressurizing nozzle 23.

[0045] The material sliding down the guide plate 31 is blown by the second pressurized nozzle 23, which separates the light and heavy materials. The heavy materials fall onto the second belt conveyor 13 for re-transport and discharge, while the light materials mixed with air are discharged from the casing 11 through the exhaust pipe 14.

[0046] Based on the above embodiments, both the first pressurizing duct 21 and the second pressurizing nozzle 23 are conical in shape.

[0047] The connection between the first pressurizing duct 21 and the middle duct 22 is a narrow end, which allows the gas entering the first pressurizing duct 21 to be pressurized by the structure of the first pressurizing duct 21 itself, and then transported to the middle duct 22 after pressurization. The outlet end of the second pressurizing nozzle 23 is also a narrow end. The gas transported to the second pressurizing nozzle 23 through the middle duct 22 will be pressurized a second time by the structure of the second pressurizing nozzle 23 itself, and the secondary pressurized air will be blown out at the outlet of the second pressurizing nozzle 23.

[0048] The guide plate 31 is inclinedly set below the discharge end of the first belt conveyor 12, and the material is obliquely guided to the lower area. The air outlet of the second pressurizing nozzle 23 is directly set below the discharge end of the guide plate 31, avoiding the conveyor belt. The airflow is no longer blocked by the conveyor belt and can directly act on the sliding material. In addition, by setting the high-pressure blowing component 2, the first pressurizing air pipe 21 and the second pressurizing nozzle 23 in a conical shape are used to realize the double pressurization of the airflow. The blown air pressure is stronger, which can accurately realize the efficient separation of heavy materials and light materials, and significantly improve the accuracy and efficiency of material sorting.

[0049] Preferably, protective pads 24 are installed on both sides of the second pressurized nozzle 23.

[0050] The protective pad 24 is made of rubber or silicone, which can convert the hard contact between the object and the protective pad 24 into a soft contact, thus protecting the second pressurized nozzle 23.

[0051] Furthermore, the distance between the feed end of the guide plate 31 and the conveyor belt of the first belt conveyor 12 is 1cm.

[0052] The guide plate 31 guides the material thrown out from the conveyor belt of the first belt conveyor 12, and the small gap between the guide plate 31 and the first belt conveyor 12 prevents the conveyor belt of the first belt conveyor 12 from carrying the material into the top of the first pressurizing air duct 21.

[0053] Preferably, two sets of L-shaped support frames 32 are fixedly connected to the bottom surface of the guide plate 31. The sides of the L-shaped support frames 32 abut against the inner wall of the first belt conveyor 12, and the guide plate 31 is supported by the L-shaped support frames 32.

[0054] In one installation method of the L-shaped support frame 32, each L-shaped support frame 32 is provided with a connecting screw hole 33, the first belt conveyor 12 is provided with a through hole, and a bolt is provided in the through hole. The L-shaped support frame 32 is installed on the first belt conveyor 12 through the connecting screw hole 33 and the bolt.

[0055] Align the connecting screw hole 33 of the L-shaped support frame 32 on the guide plate 31 with the through hole on the first belt conveyor 12, and pass one end of the bolt through the through hole and screw it onto the connecting screw hole 33 to complete the connection between the L-shaped support frame 32 and the first belt conveyor 12, thereby fixing the guide plate 31.

[0056] In this installation method, the L-shaped support frame 32 is detachably connected to the first belt conveyor 12, which facilitates the replacement and maintenance of the guide plate 31.

[0057] Another installation method for the L-shaped support frame 32 is to weld the L-shaped support frame 32 onto the first belt conveyor 12.

[0058] In this installation method, the L-shaped support frame 32 is fixedly connected to the first belt conveyor 12, providing high stability for the support of the guide plate 31.

[0059] Furthermore, baffle plates 34 are fixedly connected to both sides of the guide plate 31, and the guide plate 31 is a solid steel plate.

[0060] The two baffles 34 on the side of the guide plate 31 can block the material on the guide plate 31 and prevent the material from sliding off the side of the guide plate 31.

[0061] The guide plate 31 can directly block heavy materials falling from the first belt conveyor 12, preventing them from directly impacting the second pressurizing nozzle 23. By installing protective pads 24 on both sides of the second pressurizing nozzle 23, the hard contact between the heavy materials and the nozzle can be converted into a soft contact, further buffering the impact force, greatly reducing the wear of the blowing assembly, significantly extending the service life of the core components of the equipment, and reducing equipment maintenance costs.

[0062] The working principle of this embodiment is as follows: The first belt conveyor 12 transports the material to its discharge end. The material is thrown out from the conveyor belt of the first belt conveyor 12 and falls onto the guide plate 31. Since the guide plate 31 is inclined, the material falls at an angle under the guidance of the guide plate 31. At the same time, the second pressurized nozzle 23 blows air through its air outlet to separate the material sliding on the guide plate 31, so that the heavy material and the light material are separated. The heavy material falls onto the second belt conveyor 13 for re-transport and discharge. Lightweight material mixed with air is discharged from the casing 11 through the exhaust pipe 14. During this process, the protective pads 24 on both sides of the second pressurizing nozzle 23 can prevent heavy material from directly colliding with the second pressurizing nozzle 23 when it falls, thus playing a protective role. The small gap between the feed end of the guide plate 31 and the conveyor belt of the first belt conveyor 12 can prevent the conveyor belt of the first belt conveyor 12 from carrying the material into the top of the first pressurizing air pipe 21. The baffle plates 34 on both sides of the guide plate 31 can prevent the material from sliding off the side of the guide plate 31.

[0063] Example 2

[0064] The difference between this embodiment and Embodiment 1 is that: Figure 4 and Figure 5 As shown, the guide plate 31 has filter holes, and a low-pressure blowing assembly 4 for blowing air through the filter holes on the guide plate 31 is provided below the guide plate 31.

[0065] The air blown out by the low-pressure blower assembly 4 is directed to the bottom surface of the guide plate 31, and a portion of the air passes through the filter holes and enters the material, thus achieving preliminary sorting of the material. It can also accelerate the flow rate of the material on the guide plate 31 and prevent material jamming on the guide plate 31.

[0066] Preferably, the low-pressure blower assembly 4 includes a low-pressure air duct 41, the air outlet of the low-pressure air duct 41 is conical, and the exhaust end of the low-pressure air duct 41 is located below the guide plate 31.

[0067] The air outlet of the low-pressure air duct 41 is conical, which can pressurize the air discharged from the low-pressure air duct 41. The air outlet of the low-pressure air duct 41 is aligned with the guide plate 31, which can blow the pressurized air in the low-pressure air duct 41 onto the guide plate 31.

[0068] Furthermore, the air inlet end of the low-pressure duct 41 is fixedly connected to the middle duct 22.

[0069] The central air duct 22 serves as the air source for the low-pressure air duct 41, simultaneously supplying air to the low-pressure air duct 41 and the second pressurizing nozzle 23.

[0070] The usage process in this embodiment is as follows:

[0071] The first belt conveyor 12 transports the material to its discharge end. The material is thrown out from the conveyor belt of the first belt conveyor 12 and falls onto the guide plate 31 with filter holes. Since the guide plate 31 is inclined, the material falls at an angle under the guidance of the guide plate 31. At this time, the low-pressure air pipe 41 in the low-pressure blowing assembly 4 pressurizes the air introduced by the middle air pipe 22 and blows it to the bottom surface of the guide plate 31. Part of the air passes through the filter holes and enters the material to perform preliminary sorting of the material and accelerate the flow rate of the material on the guide plate 31 to avoid jamming. At the same time, the second pressurized spray pipe 23 blows air through its air outlet to further blow and sort the material that has slid down on the guide plate 31, so that the heavy material and the light material are separated. The heavy material falls onto the second belt conveyor 13 for re-transport and discharge, and the light material mixed with air is discharged from the casing 11 through the exhaust pipe 14.

[0072] Example 3

[0073] The difference between this embodiment and Embodiment 2 is as follows: Figure 6 As shown, the low-pressure blower assembly 4 includes a blower 42, and the air inlet end of the low-pressure air duct 41 is fixedly connected to the air outlet end of the blower 42.

[0074] By using blower 42 to supply air to low-pressure air duct 41 separately, the blowing volume of high-pressure blower assembly 2 will not be affected.

[0075] By setting up a low-pressure blowing assembly 4 and a filter guide plate 31, the combination of low-pressure blowing and filter guide plate 31 can not only achieve preliminary material sorting, but also accelerate the material flow rate to avoid material jamming, and adapt to the air supply conditions and material handling needs of different factories.

[0076] The usage process in this embodiment is as follows:

[0077] The first belt conveyor 12 transports the material to its discharge end. The material is thrown out from the conveyor belt of the first belt conveyor 12 and falls onto the guide plate 31 with filter holes. Because the guide plate 31 is inclined, the material falls at an angle under the guidance of the guide plate 31. At this time, the blower 42 starts and delivers air through the exhaust end to the low-pressure air pipe 41. The low-pressure air pipe 41 pressurizes the air and blows it to the bottom surface of the guide plate 31. A part of the air passes through the filter holes and enters the material to perform preliminary sorting of the material, accelerate the flow rate of the material on the guide plate 31, and avoid material jamming. At the same time, the second pressurized nozzle 23 blows air through the air outlet to further blow and sort the material that has slid off the guide plate 31, so that the heavy material and the light material are separated. The heavy material falls onto the second belt conveyor 13 for re-transport and discharge, and the light material mixed with air is discharged from the casing 11 through the exhaust pipe 14.

[0078] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
