Description

Technical Field

[0001] This invention relates to the field of waste sorting equipment technology, specifically to an intelligent waste air separator. Background Technology

[0002] Existing air classifiers mainly utilize wind power to separate materials of different densities and particle sizes into the desired light and heavy substances. The main structure of an air classifier includes a feed belt conveyor, a fan, air nozzles, a diffusion chamber, a discharge belt conveyor, ventilation ducts, a rotary drum separator, a dust removal device, and fan control valves.

[0003] Household and industrial waste typically have complex compositions; their composition varies within the same area at different times, and even more so between different regions. Existing air-separation equipment has several drawbacks in waste sorting:

[0004] 1. When the air classifier is in operation, the air speed of the nozzle is controlled by the worker by adjusting the air duct valve or adjusting the fan frequency. The worker's adjustment efficiency is low, and the air classifier cannot sort according to the characteristics of the material.

[0005] Second, gas easily leaks out of the diffuser outlet;

[0006] Third, light waste inside the diffusion chamber tends to be pushed up near the outlet and is not easily discharged.

[0007] Fourth, before entering the separation chamber, the garbage on the conveyor belt is transported unevenly. After entering the separation chamber, the garbage cannot be evenly exposed to air, resulting in a lower garbage sorting efficiency.

[0008] 5. It is not possible to monitor the real-time output and flow rate of the air separator's feed and discharge. Summary of the Invention

[0009] Technical problems to be solved

[0010] To address the aforementioned shortcomings of existing technologies, this invention provides an intelligent waste air separator that effectively solves the problem of poor air separation caused by workers adjusting duct valves or fan frequency in existing air separators.

[0011] Technical solution

[0012] To achieve the above objectives, the present invention provides the following technical solution:

[0013] This invention provides an intelligent waste air separator, comprising a blower, a feeding conveyor, a diffusion chamber, and a nozzle. A rotating drum separation mechanism is connected between the feeding conveyor and the diffusion chamber. The nozzle is located at the end of the feeding conveyor and between the rotating drum separation mechanism, and is connected to the blower via an air supply pipe. It also includes a pressure drum mechanism, which is located above the feeding conveyor and mainly comprises a support frame, a pressure drum, a displacement sensor, and a slider. The pressure drums are arranged parallel to each other above the feeding conveyor. The slider is slidably connected to the support frame, and both ends of the pressure drum are rotatably connected to the slider. The displacement sensor is used to acquire the sliding displacement of the slider.

[0014] The feeding conveyor is equipped with a speed detector for detecting belt speed, and a set of flat idlers is spaced apart below the belt on its upper side. The bottom of the flat idlers is connected to a weighing sensor; the air supply duct is equipped with a wind speed sensor for monitoring the wind speed delivered through the nozzle, and the fan is equipped with a frequency conversion speed control unit.

[0015] Furthermore, a discharge conveyor is provided on the lower side of the diffusion chamber, and a rotatable drive roller is provided at the discharge port of the diffusion chamber.

[0016] Furthermore, multiple air intake boxes are distributed on the top of the diffusion chamber, and ventilation ducts are connected to the air intake boxes. The ventilation ducts connect the fan to the interior of the diffusion chamber, and electric valves are installed on the ventilation ducts.

[0017] Furthermore, the drum separation mechanism includes a housing, a drum, and a reduction drive motor. The housing is a through-hole housing, and the drum is rotatably connected to the housing. A material discharge port is provided at the bottom of the housing located on the front side of the drum. The reduction drive motor is linked to the drum.

[0018] Furthermore, a scraper is fixed diagonally below the drum, with the upper edge of the scraper blade close to the drum.

[0019] Furthermore, the mouthpiece can be angled within the range of 0-90°.

[0020] Furthermore, the support frame is fixed on the support plate, and slide rails are vertically fixed on both sides of the support frame. A slide groove matching the slider is formed between the slide rails. The main body of the displacement sensor is fixed on the support frame, and the outer end of the pull rod of the displacement sensor is fixedly connected to the slider.

[0021] Beneficial effects

[0022] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0023] The real-time mass transport volume can be obtained by using the bearing surface of the flat idler roller equipped with a weighing detector under the belt of the feeding conveyor and the speed sensor. At the same time, a pressure drum mechanism is designed on the feeding conveyor. The pressure drum uses its own weight to press the garbage to a certain distance. The displacement sensor obtains the displacement of the pressure drum, thereby obtaining the cross-sectional area of ​​the garbage on the feeding conveyor per unit time. Then, based on the mass transport volume, the density of the garbage after being flattened can be obtained. After automatically obtaining real-time monitoring of the feed flow rate and density, the wind speed of the blower is automatically adjusted, which greatly improves the sorting efficiency and sorting purity.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] The present invention will be further described below with reference to embodiments.

[0034] Example:

[0035] This invention provides an intelligent waste air separator. This equipment is used in landfills for the sorting of waste after crushing and screening. The crushed and screened waste enters the belt conveyor 20. As is known from the principle of air separation, the air velocity at the nozzle 40 is a crucial operating parameter of the air separator. While ensuring that the waste particle size remains within a certain range, the air separator primarily sorts by particle density.

[0036] Reference Figure 1-2 The main components of the air separator include a blower 10, a feeding conveyor 20, a diffusion chamber 30, and nozzles 40. A rotating drum 62 and a separation mechanism 60 connect the feeding conveyor 20 and the diffusion chamber 30. The nozzles 40 are located at the end of the feeding conveyor 20 and between the rotating drum 62 and the separation mechanism 60, and are connected to the blower 10 via an air supply pipe. The blower 10, feeding conveyor 20, diffusion chamber 30, and nozzles 40 are the basic components of the waste air separator. The blower 10 mainly provides airflow at a certain speed, which is blown out through the nozzles 40 to separate the crushed waste. The air separation process is based on the settling characteristics of various solid wastes in the air, thereby achieving the purpose of classification, recycling, and reuse. The diffusion chamber 30 is mainly used for the settling of lightweight waste separated by the nozzles 40, and a discharge conveyor 100 is installed below the diffusion chamber 30 for output. However, the diffusion chamber 30 in this solution differs from that in the prior art in that a rotatable drive roller 110 is provided at the discharge port of the diffusion chamber 30. The rotation of the drive roller 110 is used to actively flatten the light waste that settles on the discharge conveyor 100 and discharge it to the outside, thus preventing the light waste from easily expanding and accumulating.

[0037] The air separator also includes a pressure drum 52 mechanism 50, see reference. Figure 3 The drum 52 mechanism 50 is one of the core components of intelligent product design:

[0038] The main body of the pressing drum 52 mechanism 50 is located on the upper side of the feeding conveyor 20. Its structure mainly includes a support frame 51, a pressing drum 52, a displacement sensor 53, and a slider 54. The pressing drum 52 is arranged parallel to each other above the feeding conveyor 20. The slider 54 is slidably connected to the support frame 51. Both ends of the pressing drum 52 are rotatably connected to the slider 54. The pressing drum 52 has a built-in motor. The pressing drum 52 uses its own weight to press the crushed waste transported by the feeding conveyor 20 down to a certain extent. The displacement sensor 53 is used to obtain the sliding displacement of the slider 54. Since the slider 54 and the rotating shaft of the pressing drum 52 are integrated, it obtains the displacement of the pressing drum 52 when pressing the waste. By using its own weight to press the loose waste to a certain distance, a relatively "compacted" effect is achieved. The displacement sensor 53 will obtain a displacement of the pressing drum 52, thereby obtaining the cross-sectional area of ​​the waste on the feeding conveyor 20 per unit time. Based on the continuously changing cross-sectional area, the volume of waste per unit time is obtained by integration.

[0039] The feeding conveyor 20 is equipped with a speed detector 70 for detecting belt speed. A set of flat idlers 80 is spaced below the belt on its upper side. Weighing sensors 90 are connected to the bottom of each flat idler 80. During operation, waste passes over the bearing surface of the flat idlers 80 equipped with the weighing detector, and the mass of waste transported is determined by combining this data with the belt speed detected by the speed sensors. Based on the obtained waste volume, the density of the corresponding portion of waste can be obtained using the density formula: ρ = m / V.

[0040] The air supply duct is equipped with a wind speed sensor to monitor the wind speed delivered through the nozzle 40. The blower 10 is equipped with a variable frequency speed control unit, which uses a programmable frequency converter. When obtaining the density of the garbage that is about to fall and be blown apart by the feeding conveyor 20, the blower 10 can be automatically adjusted to the speed of separating light materials by adjusting the frequency.

[0041] In addition, by adding a drive roller 110 to the outside of the diffusion chamber 30, the leakage of gas from the diffusion chamber 30 to the outside can be reduced, providing a more sealed negative pressure environment. At the same time, by installing a speed detector 70 for detecting belt speed on the discharge conveyor 100, a set of flat idlers 80 is provided at intervals under the belt on the upper side of the conveyor. The bottom of the flat idlers 80 is connected to a weighing sensor 90. With the same calculation method as the feeding conveyor 20, the density and flow rate of the light material can be obtained by using the information collected by the speed detector 70 and the weighing sensor 90, forming a closed-loop internal feedback mechanism to correct the automatically adjusted wind speed and further improve the sorting purity.

[0042] Reference Figure 4-6Specifically, the drum 62 separation mechanism 60 includes a housing 61, a drum 62 and a reduction drive motor 63. The housing 61 is a through housing 61 that is used to connect the front and rear working units. The drum 62 is rotatably connected to the housing 61. A material discharge port 64 is opened at the bottom of the housing 61 located on the front side of the drum 62. The reduction drive motor 63 is linked with the drum 62.

[0043] The specific waste separation process is as follows: after the waste falls into the rotating drum 62 of the separation mechanism 60, it is broken up and then separated by the airflow of the nozzle 40. The separated heavy material falls directly through the discharge port 64 to the heavy material collection point below; the light material is carried into the diffusion chamber 30 by the airflow. The airflow is diffused in the diffusion chamber 30, and then the light material after the air and material are separated falls onto the discharge conveyor 100 due to gravity and is then output outside the diffusion chamber 30.

[0044] In specific installation and implementation, the speed detector 70 in this embodiment is an existing technology product, consisting of a wheel speed meter and a controller. The wheel speed meter can be installed on the conveyor belt. The flat idler 80 is connected to the idler support frame 51, which is then fixed to the detection surface of the S-type load cell 90. The support frame 51 is fixed to the support plate 120, and slide rails 55 are vertically fixed on both sides of the support frame 51. The slide rails 55 form a groove that matches the slider 54. The main body of the displacement sensor 53 is fixed to the support frame 51, and the outer end of the pull rod of the displacement sensor 53 is fixedly connected to the slider 54.

[0045] Reference Figure 1 In this embodiment, multiple suction boxes 31 are preferably distributed on the top of the diffusion chamber 30. Ventilation ducts 32 are connected to the suction boxes 31, and the ventilation ducts 32 connect the fan 10 to the interior of the diffusion chamber 30. An electric valve 33 is installed on the ventilation ducts 32. The multiple suction boxes 31, in conjunction with the fan 10, ensure that the diffusion chamber 30 maintains a negative pressure suction environment, resulting in better separation of light materials and air, and facilitating the falling of light materials. Simultaneously, the negative pressure suction prevents the gas inside from leaking outside the diffusion chamber 30, reducing pollution to the external environment. The gas partially drawn back through the ventilation ducts 32 is treated by subsequent dust removal equipment before being discharged.

[0046] Meanwhile, in this solution, a scraper 65 is fixed at the lower side of the rotating drum 62. The upper blade of the scraper 65 is close to the rotating drum 62. The scraper 65 is designed to work with the rotatable rotating drum 62 to facilitate the scraping of the attached substances on the surface of the rotating drum 62.

[0047] Furthermore, the nozzle 40 in this design is adjustable within a 0-90° range. The angles of the feeding conveyor 20 and the air nozzle 40 are adjustable from 0-90°, allowing for flexible adjustment of the feeding angle and nozzle 40 angle according to the material composition to achieve the desired air separation effect. Simultaneously, the distance between the nozzle 40 and the rotating drum 62 is adjustable for even better air separation performance.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
