Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a block diagram of a construction waste disposal system provided in accordance with one embodiment of the present disclosure. As shown in fig. 1, the system 10 may include a conveying device 11, an identification device 12, a control device 13, and an air selection device 14. The conveying device 11 is connected with a control device 13, the recognition device 12 is connected with the control device 13, and the control device 13 is connected with the winnowing device 14.
The conveyor 11 can be used for conveying construction waste. The recognition device 12 may be configured to recognize whether or not there is a foreign matter in the construction waste in the case where the construction waste exists on the conveyor device 11, and determine position information indicating a position where the foreign matter exists in the case where the foreign matter is lighter than the aggregate in the construction waste. The control device 13 may be configured to determine a target operation period of the air classification device 14 corresponding to the position information based on the position of the impurity, the position of the air classification device 14, and the conveying speed of the conveying device 11. The control device 13 can also be used for controlling the air separation device 14 to work in the target working period so as to separate the aggregates and the impurities in the construction waste.
The conveying device 11 may be a conveyor belt, for example. The construction waste can be construction demolition waste, construction residue soil and the like.
In the case where construction waste exists on the conveyor 11, the recognition device 12 may recognize whether or not there is a foreign matter in the construction waste, and in the case where there is a foreign matter, determine position information indicating a position where the foreign matter is located. Wherein the conveyor means 11 may be provided with corresponding sensors to determine the presence of construction waste thereon. Illustratively, the sensor may be an image sensor, a contact sensor, a pressure sensor, or the like. The identification device 12 may be arranged near the conveyor device 11, near the air classification device 14. For example, the identification device 12 may be disposed at a distance of 0.1m to 2m from the air separation device 14. The identification device 12 can identify whether the impurities exist in the construction waste through any one or more of laser detection, ray detection, image detection and the like, and can identify the positions of the impurities under the condition that the impurities exist.
The control device 13 can determine the target working time interval of the air classification device 14 corresponding to the position information identified by the identification device 12 according to the position of the impurity, the position of the air classification device 14 and the conveying speed of the conveying device 11. And the control device 13 can also be used for controlling the air separation device 14 to work in the target working period so as to separate the aggregates and the impurities in the construction wastes identified by the identification device 12 when the construction wastes reach the air separation device 14.
After the position of the impurity is determined, the distance between the current position of the impurity and the air separation device 14 can be determined according to the position of the impurity and the position of the air separation device 14, and the time length of the impurity reaching the air separation device 14 can be calculated by combining the conveying speed of the conveying device 11, and the time of the impurity reaching the air separation device 14 can be known, so that the target working time period of the air separation device 14 can be determined according to the time length. For example, the target operating period may start with the time of arrival of the foreign matter at the air classification device 14, or the target operating period may include the time of arrival of the foreign matter at the air classification device 14. The time length of the target working period may be preset, for example, the time required for the construction waste identified by the identification device 12 to pass through the air classification device 14.
For example, if the current time is 8:01:23(8 hours 01 minutes 23 seconds), the calculated time period for the impurities to reach the air classification device 14 is 2 seconds, and the time for the impurities to reach the air classification device 14 is 8:01:25, the target operation time period of the air classification device 14 can be determined according to the time. For example, the target working period may be a period of 8:01:25 to 8:01:27, where the time of the impurity reaching the air classification device 14 is the starting time of the target working period, and the duration of the target working period is 2 s. For another example, the target operation period may be a period of 8:01:23 to 8:01:27, where the time of the impurity reaching the air classification device 14 is taken as the time included in the target operation period, and the duration of the target operation period is 4 s.
After the target working period is determined, the control device 13 may control the air separation device 14 to work within the target working period, so as to separate the aggregates and the impurities from the construction wastes in the preset area when the construction wastes reach the air separation device 14.
It should be noted that the target working period is the working period of the air classification device 14 corresponding to the construction waste currently identified by the identification device 12, and for other construction waste, the system 10 provided by the present disclosure may determine the corresponding target working period in the above manner, and control the operation of the air classification device 14, so as to generate the working period of the air classification device 14 for all the construction waste conveyed on the conveying device 11.
Through the construction waste treatment system, when the conveying device conveys the construction waste, the working time of the air separation device is determined according to the existence of the impurities in the construction waste, so that when the construction waste with the impurities reaches the air separation device, the air separation device is controlled to work, and the aggregates and the impurities in the corresponding construction waste are separated. Therefore, when the building materials with impurities reach the air separation device, the air separation device can work, on one hand, the intelligent degree in the building waste treatment process can be improved, and the working pertinence of the air separation device is enhanced; on the other hand, the energy consumption of the air separation device in the construction waste treatment process can be reduced, and the noise pollution caused by the air separation device is reduced.
Fig. 2 is a block diagram of a construction waste disposal system provided in accordance with another embodiment of the present disclosure. In one possible embodiment, as shown in fig. 2, the conveyor 11 may be provided with a contact sensor 111 for detecting whether construction waste is present on the conveyor 11. The recognition means 12 is adapted to operate when the contact sensor 111 determines that construction waste is present on the conveyor 11. The recognition means 12 is also adapted to stop the operation when the contact sensor 111 determines that the construction waste is not present on the conveyor 11 for a preset time period.
In one case, the contact sensor 111 may be connected to the recognition device 12 (not shown in fig. 2), and the recognition device 12 may start to operate when the contact sensor 111 detects the presence of construction waste on the conveyor 11, and recognize whether the construction waste has impurities. And, the recognition means 12 may also start timing when the contact sensor 111 determines that there is no construction waste on the conveyor 11, and stop operating when the timing period reaches a preset period.
In another case, the contact sensor 111 may be connected to the control device 13 (not shown in fig. 2), and the control device 13 may send a corresponding control command to the identification device 12 when the contact sensor 111 detects that the construction waste exists on the conveying device 11, so as to trigger the identification device 12 to operate to identify whether the construction waste contains impurities. And when the contact sensor 111 detects that no construction waste exists on the conveying device 11, the control device 13 may start timing, and if the timing duration reaches a preset duration, the control device 13 may send a corresponding control instruction to the identification device 12 to stop the identification device 12.
Through the scheme, the identification device does not work when no construction waste exists on the conveying device, and the identification device works when the construction waste exists on the conveying device so as to identify impurities in the construction waste, so that the identification pertinence of the identification device can be enhanced, and the workload of the identification device is reduced.
In a possible embodiment, the recognition device 12 can recognize the impurities in the construction waste by means of image detection. In such an embodiment, as shown in fig. 2, the recognition device 12 may include an image acquisition module 121 and a recognition module 122 connected to the image acquisition module 121. The image collecting module 121 is used for collecting image information of construction waste. The identification module 122 is configured to determine whether impurities exist in the construction waste according to the image information acquired by the image acquisition module 121, and determine positions of the impurities according to the image information.
Illustratively, the image acquisition module 121 may be a camera. The recognition module 122 is connected to the image capturing module 121, and can determine whether there is any impurity in the construction waste according to the captured image information. For example, the identification module 122 may store feature information corresponding to the impurities in advance, and if the identification module 122 has information that can be matched with the feature information in the image information acquired by the image acquisition module 121, it may be determined that the impurities exist in the construction waste corresponding to the image information acquired by the image acquisition module 121. And the position of the impurity and the content of the impurity can be determined according to the position and the proportion of the matched information.
In one possible embodiment, a rotary encoder 112 may be provided on the transport device 11 for recording the travel distance of the transport device 11. The recognition device 12 operates once every time the travel distance reaches a preset distance to recognize whether impurities exist in the construction waste.
In one case, the rotary encoder 112 may be coupled to the identification appliance 12 to trigger the identification appliance 12 to operate once each time the travel distance reaches a predetermined distance. In another case, the rotary encoder 112 may be connected to the control device 13, and the control device 13 records the travel distance of the rotary encoder 112, and the control device 13 sends a triggering instruction to the identification device 12 to trigger the identification device 12 to operate every time the travel distance reaches a preset distance.
The running distance refers to the distance that the construction waste on the conveying device 11 moves during conveying, and taking the conveying device 11 as a conveyor belt as an example, if the conveying length of the conveyor belt is 5m, when the same construction waste is conveyed from one end of the conveyor belt to the other end, the running distance of the conveyor belt is 5 m. The preset distance may be less than or equal to the length of the conveying device 11 for conveying the construction waste, if the preset distance is equal to the length of the conveying device 11, then when the construction waste exists on the conveying device 11, the identifying device 12 may identify all the construction waste currently conveyed on the conveying device 11, and when the running distance of the conveying device 11 reaches the preset distance, the construction waste on the conveying device 11 is completely conveyed, and at this time, the construction waste on the conveying device 11 is new construction waste which is not identified by the identifying device 12, so that the identifying device 12 may work again to identify the construction waste. Like this, can uninterruptedly discern the building rubbish on the conveyor, discernment impurity wherein promotes the intelligence to impurity discernment in the building rubbish.
In one possible embodiment, the air classification device 14 comprises a wind box 141 and a fan 142. The wind box 141 receives the construction waste conveyed by the conveying device 11 through the feeding port, and when the air separation device 14 works, the fan 142 is started and blows air to the construction waste through a nozzle thereof to separate aggregates and impurities in the construction waste. Wherein the fan 142 is equipped with a high pressure nozzle.
In a possible embodiment, the air separation device 14 further comprises two discharge ports for separately discharging the separated aggregates and impurities for subsequent use.
In one possible embodiment, the construction waste disposal system 10 provided by the present disclosure may further include a display screen connected to the control device 13. If there is impurity in the discernment building rubbish identification device 12, can further confirm the position of impurity and the content of impurity to the impurity information who contains impurity position and impurity content sends controlling means 13, and controlling means 13 can send impurity information to the display screen and show, so that relevant staff knows.
Fig. 3 is a flowchart of a construction waste treatment method according to an embodiment of the present disclosure. The method can be applied to the construction waste treatment system mentioned above. The construction waste treatment system can comprise a conveying device, a recognition device, a control device and an air separation device. As shown in fig. 3, the method may include the following steps.
In step 31, in the case where construction waste exists on the conveyor, it is identified whether or not there is a foreign matter in the construction waste, and in the case where there is a foreign matter, position information indicating a position where the foreign matter is located is determined.
In the case of construction waste on the conveyor, it is possible to identify whether there are impurities in the construction waste and, in the case of impurities, to determine the location of the impurities. The conveyor may be provided with a corresponding sensor to determine whether construction waste is present thereon. Illustratively, the sensor may be an image sensor, a contact sensor, a pressure sensor, or the like. Through any one or more of laser detection, ray detection, image detection and the like, whether impurities exist in the construction waste or not can be identified, and meanwhile, the positions of the impurities can also be identified.
In one embodiment, identifying whether impurities are present in the construction waste may include the steps of:
acquiring image information of construction waste;
and determining whether the impurities exist in the construction waste or not according to the image information.
If it is determined from the image information that the construction waste contains the foreign matter, the position of the foreign matter can be determined from the image information.
Illustratively, the image information of the construction waste can be acquired through a camera. After the image information of the construction waste is acquired, whether the impurities exist in the construction waste can be determined according to the image information. For example, feature information corresponding to the foreign matter may be stored in advance, and if there is information that can be matched with the feature information in the acquired image information, it may be determined that the foreign matter is present in the construction waste corresponding to the image information. And the position of the impurity and the content of the impurity can be determined according to the position and the proportion of the matched information.
In step 32, determining a target working time period corresponding to the position information according to the position of the impurity, the position of the air separation device and the conveying speed of the conveying device;
after the position of the impurity is determined, the distance between the current impurity and the air separation device can be determined according to the position of the impurity and the position of the air separation device, meanwhile, the time length of the impurity reaching the air separation device can be calculated by combining the conveying speed of the conveying device, the time of the impurity reaching the air separation device can also be known, and the target working time interval can be determined according to the time length. For example, the target operating period may start with the time when the foreign matter arrives at the air classification device, or the target operating period may include the time when the foreign matter arrives at the air classification device. The time length of the target working period may be preset, for example, the time required for all the construction waste corresponding to the acquired image information to pass through the air separation device. The target operating period may be an operating period for the air classification device.
For example, if the current time is 8:01:23(8 hours 01 minutes 23 seconds), the calculated time period for the impurities to reach the air classification device is 2 seconds, and the time for the impurities to reach the air classification device is 8:01:25, the target operation time period of the air classification device can be determined according to the time. For example, the target working period may be a period of 8:01:25 to 8:01:27, where the time when the impurity reaches the air classification device is taken as the starting time of the target working period, and the duration of the target working period is 2 s. For another example, the target working period may be a period of 8:01:23 to 8:01:27, where the time of the impurity reaching the air classification device is taken as the time included in the target working period, and the duration of the target working period is 4 s.
In step 33, the construction waste is air-sorted in the target working period.
After the target working period is determined, the construction waste can be winnowed in the target working period. For example, the air separation device is controlled to work in a target time period, and the air separation device blows air to the construction waste through the nozzle to separate aggregates and impurities in the construction waste.
It should be noted that the target working period herein is a working period corresponding to the currently identified construction waste, and for other construction waste, another target working period is correspondingly generated, and the corresponding construction waste is winnowed in the corresponding target working period, so that all the construction waste conveyed on the conveying device can be winnowed.
Through the scheme, when the conveying device conveys the construction waste, the air separation time is determined according to the existence of the impurities in the construction waste, so that the construction waste with the impurities is subjected to air separation when reaching an air separation position (for example, the position of the air separation device), and the aggregates and the impurities in the corresponding construction waste are separated. Therefore, when the building materials with impurities reach the air separation position, the building materials are subjected to air separation, on one hand, the intelligent degree in the building waste treatment process can be improved, and the pertinence of air separation is enhanced; on the other hand, the energy consumed by air separation operation in the construction waste treatment process can be reduced, and meanwhile, the noise pollution caused by the air separation operation is reduced.
In one possible embodiment, the method provided by the present disclosure may further include the steps of:
acquiring the running distance of the conveying device;
The preset distance can be smaller than or equal to the length of the conveying device, if the preset distance is equal to the length of the conveying device, all construction wastes currently conveyed on the conveying device are identified when the construction wastes exist on the conveying device, and when the running distance of the conveying device reaches the preset distance, all the construction wastes are completely conveyed, and at the moment, the construction wastes on the conveying device are new construction wastes which are not identified, so that the construction wastes can be identified again. Like this, can uninterruptedly discern the building rubbish on the conveyor, discernment impurity wherein promotes the intelligence to impurity discernment in the building rubbish.
