Referring to fig. 1, the air classifier according to the embodiment of the present invention includes a feeding device 100, an air injection device 200, a receiving device 300, and a conveying device 400. The air jet of the air jet device 200 is located below the discharge port of the feeding device 100, the air jet direction of the air jet forms an obtuse angle with the gravity direction of the material falling from the discharge port to order the material to make a projectile motion, the number of the receiving devices 300 is three, the three receiving devices 300 are sequentially arranged along the horizontal direction of the material motion, the first receiving device 300 is located below the discharge port, the conveying device 400 is arranged between the two adjacent receiving devices 300, and the conveying device 400 can convey the material falling onto the conveying device 400 and convey the material to the receiving device 300 located at the tail end of the conveying stroke. It should be noted that the three receiving devices 300 are sequentially arranged along the horizontal direction of the movement of the material, the three receiving devices 300 may be located on the same horizontal line, and of course, the receiving devices 300 may also be adjusted in position along the vertical direction according to the actual situation.
Through the structure, the weight of the materials is different, and the projectile motion of the materials under the action of the air injection device 200 is different, so that the materials with various weight types can be separated in one separation process. The weight of the material is different, the stress of the material when falling out of the discharge port is different, and the movement of the material is different, so that the three receiving devices 300 can receive the heavy material, the second heavy material and the light material with different weight categories. In some embodiments, the receiving device 300 may be configured to receive four, five, etc. items of different weight categories.
In order to reduce the interference of the outside to the material winnowing, the winnowing machine further comprises a settling chamber 500, a discharge port and an air jet are arranged on one side of the settling chamber 500, the conveying device 400 is arranged in the settling chamber 500, the settling chamber 500 is provided with three through ports 510, and the through ports 510 and the material receiving devices 300 are arranged in a one-to-one correspondence mode.

The air inlet of the air nozzle 220 is communicated with the air outlet of the fan 210 through a first pipe 610, and the air nozzle 220 is provided with the air nozzle.
In order to increase the functional abundance of the air injection device 200, a purging device 700 is further included, and an air inlet of the purging device 700 is communicated with the first pipeline 610 through a second pipeline 620, wherein the purging device 700 may be provided as a dust remover, a purging nozzle, or the like.

Therefore, by adjusting the air volume ratio entering the purging device 700 and the settling chamber 500, a negative pressure state can be assumed in the settling chamber 500, and finally, the dust inside the settling chamber 500 does not leak out. Meanwhile, the third duct 630 is provided with an air regulating valve 640 at an air inlet of the blower 210 to regulate an intake air amount.

The garbage winnowing method of the embodiment of the invention is described as follows.
Referring to fig. 1 and 2, the winnowing parameter library typically includes a plurality of sets of winnowing parameters, which may be obtained from other winnowing machines of the same type and directly imported into the server 900 for use. Each group of winnowing parameters comprises a group of warehouse-in material components, warehouse-in target materials and corresponding warehouse-in feeding wind speeds, and different warehouse-in material components and different warehouse-in target materials need corresponding different warehouse-in feeding wind speeds so as to enable the winnowing machine to successfully perform garbage winnowing subsequently.
During air separation, a client needs to set the components of a material to be selected and a target material to be selected, so that the components of the material to be selected and the target material to be selected can be quickly scanned in an air separation parameter library for the components of the material in the library and the target material in the library after automatic air separation is selected; once the matching is consistent, the components of the in-store materials and the in-store feeding wind speed corresponding to the in-store target materials are obtained, and the in-store feeding wind speed is used as the target feeding wind speed to adjust the real-time feeding wind speed at the air nozzle 220 of the air separator so as to complete garbage air separation in the subsequent process; once the matching is not consistent, the automatic adjustment cannot be finished, and at the moment, a user is informed to carry out manual adjustment until the real-time feeding wind speed of the air nozzle 220 of the air separator meets the requirement of air separation of garbage, and the real-time feeding wind speed is the target feeding wind speed; after the target feeding wind speed is determined, the target feeding wind speed is recorded as an in-warehouse feeding wind speed, and the corresponding components of the material to be selected and the target material to be selected are recorded as the components of the material to be selected and the target material to be selected, and are stored in the air separation parameter library, so that the subsequent automatic selection can be rapidly carried out after the same components of the material to be selected and the target material to be selected are met, and manual adjustment is not needed. Therefore, after the operation times are more, the more sufficient the winnowing parameters in the winnowing parameter library are, the degree of manual participation can be greatly reduced, and the garbage winnowing speed can be improved.
It should be noted here that the adjustment of the real-time feeding air speed at the air nozzle 220 of the air separator is mainly achieved by adjusting the fan frequency, the opening of the air regulating valve and the opening of the flow dividing valve of the air separator. In some embodiments of the invention, all material components refer to components of mixed waste, such as: scrap iron, foam, plastic, etc.; all target materials refer to weight categories such as: heavy, sub-heavy, and light; therefore, after the material composition and the target material are determined, a better feeding air speed and a better settling chamber partial pressure can be found.
According to the garbage winnowing method provided by the embodiment of the invention, a winnowing parameter library is established to provide a basis for automatically selecting winnowing parameters; the automatic sorting adjustment is realized by automatically matching the winnowing parameters in the winnowing parameter library; meanwhile, when automatic winnowing cannot be carried out, manual supplementary adjustment can be carried out, and winnowing parameters of manual winnowing can be stored, so that a winnowing parameter library is enlarged, and the subsequent automatic winnowing capability is improved. Compared with the traditional winnowing method, the garbage winnowing method greatly reduces the dependence on manual adjustment, can continuously expand a winnowing parameter library along with the increase of the use time, and reduces the frequency of manual participation.
In some embodiments of the present invention, the above garbage winnowing method further comprises the following steps:
manual air separation: manually adjusting the fan frequency, the opening of an air adjusting valve and the opening of a flow dividing valve of the air separator according to the components of the material to be selected and the target material to be selected until the real-time feeding air speed of the air separator reaches the target feeding air speed; and storing the target feeding air speed, the corresponding components of the material to be selected and the target material to be selected as a group of winnowing parameters into a winnowing parameter library.
The manual air separation is a means for directly and manually adjusting the fan frequency, the opening of an air adjusting valve and the opening of a shunt valve of the air separator, the real-time feeding air speed of the air separator is adjusted to the air speed capable of realizing garbage air separation by adjusting the fan frequency, the opening of the air adjusting valve and the opening of the shunt valve, the air speed is the target feeding air speed, and after the air separation is realized, the target feeding air speed, the corresponding components of the material to be selected and the target material to be selected are stored in an air separation parameter library and used as a group of air separation parameters. Manual winnowing is not a simple supplement to automatic winnowing, and whether manual winnowing is performed or not can be selected firstly in actual operation, so that automatic winnowing is avoided when fewer or missing winnowing parameters exist in a winnowing parameter library.
In some embodiments of the invention, each set of winnowing parameters further comprises in-silo settling chamber wind pressure; the automatic winnowing further comprises the following steps:
if the matching is successful, the corresponding in-warehouse settling chamber air pressure is used as the target settling chamber air pressure for controlling the air separator; controlling the fan frequency, the opening of an air adjusting valve and the opening of a flow dividing valve of the air separator according to the air pressure of the target settling chamber;
if the matching fails, the fan frequency, the opening degree of the air adjusting valve and the opening degree of the flow dividing valve of the air separator are manually adjusted until the air pressure of a real-time settling chamber of the air separator reaches the air pressure of a target settling chamber, and the air pressure of the target settling chamber, the air speed of target feeding, corresponding components of the material to be selected and the target material to be selected are stored into an air separation parameter library as a group of air separation parameters.
The real-time settling chamber wind pressure in the settling chamber 500 can also influence the effect of garbage winnowing, if the negative pressure of the settling chamber 500 is too large, light materials are not easy to settle on the discharging conveyor, and if the settling chamber 500 is positive pressure, dust is easy to leak. Therefore, the air pressure of the in-store settling chamber can be further included in the air separation parameters, and each air pressure of the in-store settling chamber is set according to the corresponding component of the material to be selected and the target material to be selected, or is a manual setting parameter which is actually subjected to air separation in historical operation.
After the components of the material to be selected and the target material to be selected are obtained, matching can be carried out, when matching is successful, not only the in-store feeding air speed but also the in-store settling chamber air pressure can be obtained, and then the fan frequency, the air regulating valve opening degree and the shunt valve opening degree of the winnowing machine are controlled according to the target feeding air speed and the target settling chamber air pressure.
It should be noted that the main factors affecting the real-time feeding wind speed are the opening degree of the air regulating valve, the frequency of the fan and the opening degree of the shunt valve, and the main factors affecting the real-time air pressure of the settling chamber are the opening degree of the shunt valve, so that the target feeding wind speed and the target air pressure of the settling chamber can be finally achieved by adjusting the opening degree of the air regulating valve, the opening degree of the shunt valve and the frequency of the fan.
In some embodiments of the invention, the manual air classification further comprises the steps of:
manually adjusting the fan frequency, the opening of an air adjusting valve and the opening of a flow dividing valve of an air separator of the air separator according to the components of the material to be selected and the target material to be selected until the air pressure of a real-time settling chamber of the air separator reaches the air pressure of a target settling chamber;
and storing the target feeding air speed, the target settling chamber air pressure, the corresponding components of the material to be selected and the target material to be selected into a winnowing parameter library as a group of winnowing parameters.
The real-time air pressure of the settling chamber is manually adjusted to the air pressure of the target settling chamber, and the adjustment is mainly completed by adjusting the opening of the flow divider. After the air separator is manually adjusted to the target feeding air speed and the target settling chamber air pressure which can realize garbage air separation each time, the target feeding air speed, the target settling chamber air pressure, the components of the materials to be selected and the target materials to be selected are correspondingly stored into an air separation parameter library as a group of air separation parameters for subsequent use.
In some embodiments of the invention, each in-warehouse feeding air speed corresponds to a group of in-warehouse fan frequency, in-warehouse air regulating valve opening degree and in-warehouse shunt valve opening degree. The in-warehouse feeding air speed and the in-warehouse settling chamber air pressure substantially correspond to a set of in-warehouse fan frequency, in-warehouse air regulating valve opening degree and in-warehouse shunt valve opening degree, and after the components of the materials to be selected and the target materials to be selected are obtained, the fan frequency, the air regulating valve opening degree and the shunt valve opening degree of the winnowing machine are adjusted to be consistent with the in-warehouse fan frequency, the in-warehouse air regulating valve opening degree and the in-warehouse shunt valve opening degree, so that the real-time feeding air speed and the real-time settling chamber air pressure can be quickly adjusted to the in-warehouse feeding air speed and the in-warehouse settling chamber air pressure. The adjustment time and observation time required by manual adjustment are reduced.
The garbage winnowing control system according to the second aspect of the embodiment of the present invention comprises a sensor group 810, a controller 820 and a server 900.
The sensor group 810 is used for acquiring the real-time feeding air speed of the air nozzle 220 of the winnowing machine;
the controller 820 is used for acquiring components of a material to be selected and a target material to be selected, which are set by a user, and manually adjusting the air separator to a target feeding air speed;
a server 900, in which an air separation parameter library is stored, wherein the air separation parameter library comprises a plurality of groups of air separation parameters, and each group of air separation parameters comprises different in-store material components, in-store target materials and corresponding in-store feeding air speeds; the server 900 is configured to match the corresponding in-store material components and the in-store target materials in the air separation parameter library according to the components of the material to be selected and the target material to be selected, and use the corresponding in-store feeding air speed as the target feeding air speed for controlling the air separator.
Referring to fig. 1 and 2, the winnings parameter library is stored in the server 900, and the winnings parameter library typically includes a plurality of sets of winnings parameters, which can be obtained from other winners of the same type and directly imported into the server 900 for use. Each group of winnowing parameters comprises a group of warehouse-in material components, warehouse-in target materials and corresponding warehouse-in feeding wind speeds, and different warehouse-in material components and different warehouse-in target materials need corresponding different warehouse-in feeding wind speeds so as to enable the winnowing machine to successfully perform garbage winnowing subsequently.
During air separation, a client needs to set the components of a material to be selected and a target material to be selected, so that the components of the material to be selected and the target material to be selected can be quickly scanned in an air separation parameter library for the components of the material in the library and the target material in the library after automatic air separation is selected; once the matching is consistent, the components of the in-store materials and the in-store feeding wind speed corresponding to the in-store target materials are obtained, and the in-store feeding wind speed is used as the target feeding wind speed to adjust the real-time feeding wind speed at the air nozzle 220 of the air separator so as to complete garbage air separation in the subsequent process; once the matching is not consistent, the automatic adjustment cannot be finished, and at the moment, a user is informed to carry out manual adjustment until the real-time feeding wind speed of the air nozzle 220 of the air separator meets the requirement of air separation of garbage, and the real-time feeding wind speed is the target feeding wind speed; after the target feeding wind speed is determined, the target feeding wind speed is recorded as an in-warehouse feeding wind speed, and the corresponding components of the material to be selected and the target material to be selected are recorded as the components of the material to be selected and the target material to be selected, and are stored in the air separation parameter library, so that the subsequent automatic selection can be rapidly carried out after the same components of the material to be selected and the target material to be selected are met, and manual adjustment is not needed. Therefore, after the operation times are more, the more sufficient the winnowing parameters in the winnowing parameter library are, the degree of manual participation can be greatly reduced, and the garbage winnowing speed can be improved.
It should be noted here that the adjustment of the real-time feeding air speed at the air nozzle 220 of the air separator is mainly achieved by adjusting the fan frequency, the opening of the air regulating valve and the opening of the flow dividing valve of the air separator.
According to the garbage winnowing control system provided by the embodiment of the invention, interaction with a user can be realized through the controller 820, the collection of user input data is completed, and meanwhile, the target feeding air speed of the winnowing machine can be manually adjusted; the server 900 can automatically select the target feeding wind speed, and further can greatly reduce the adjusting time. The garbage winnowing control system greatly reduces the dependence on manual adjustment, can continuously expand a winnowing parameter library along with the increase of the use time, and reduces the frequency of manual participation.
In some embodiments of the present invention, the sensor cluster 810 is also used to collect real-time settling chamber wind pressure in the settling chamber 500 of the air classifier. Each group of air separation parameters also comprises air pressure of a settling chamber in the warehouse; the controller 820 is also used to manually adjust the air pressure of the air classifier to the target settling chamber; the server 900 is configured to match corresponding in-store material components and in-store target materials in the air separation parameter library according to the components of the material to be selected and the target material to be selected, and use the corresponding in-store feeding air speed and the in-store settling chamber air pressure as the target feeding air speed and the target settling chamber air pressure for controlling the air separator. The real-time settling chamber wind pressure in the settling chamber 500 can also influence the effect of garbage winnowing, if the negative pressure of the settling chamber 500 is too large, light materials are not easy to settle on the discharging conveyor, and if the settling chamber 500 is positive pressure, dust is easy to leak. Therefore, the air pressure of the storehouse settling chamber can be included in the air separation parameters. It should be noted that the main factors affecting the real-time feeding wind speed are the opening degree of the air regulating valve, the frequency of the fan and the opening degree of the shunt valve, and the main factors affecting the real-time air pressure of the settling chamber are the opening degree of the shunt valve, so that the target feeding wind speed and the target air pressure of the settling chamber can be finally achieved by adjusting the opening degree of the air regulating valve, the opening degree of the shunt valve and the frequency of the fan.
In some embodiments of the present invention, the controller 820 may directly use a display control device for control and human-computer interaction, for example: a computer, a liquid crystal touch control device, or the like may be employed. The sensor group 810 can adopt a wind speed sensor to measure the real-time feeding wind speed and a micro-pressure sensor to measure the real-time settling chamber wind pressure
In some embodiments of the invention, each in-warehouse feeding air speed corresponds to a group of in-warehouse fan frequency, in-warehouse air regulating valve opening degree and in-warehouse shunt valve opening degree. The in-warehouse feeding air speed and the in-warehouse settling chamber air pressure substantially correspond to a set of in-warehouse fan frequency, in-warehouse air regulating valve opening degree and in-warehouse shunt valve opening degree, and after the components of the materials to be selected and the target materials to be selected are obtained, the fan frequency, the air regulating valve opening degree and the shunt valve opening degree of the winnowing machine are adjusted to be consistent with the in-warehouse fan frequency, the in-warehouse air regulating valve opening degree and the in-warehouse shunt valve opening degree, so that the real-time feeding air speed and the real-time settling chamber air pressure can be quickly adjusted to the in-warehouse feeding air speed and the in-warehouse settling chamber air pressure. The adjustment time and observation time required by manual adjustment are reduced.
