[0002] Construction waste refers to construction waste generated during construction due to human or natural reasons, including waste soil, abandoned soil, waste concrete, steel bars and abandoned materials. If not handled and utilized in a timely manner, it will inevitably have adverse effects on society, the environment and resources.

[0003] Related technologies can refer to the Chinese patent publication number CN118162263A, which discloses a construction waste recycling and processing device, including a shell, the interior of the shell is divided into a crushing chamber, an aggregate chamber and a working chamber, and the top of the crushing chamber is connected with a feed funnel, and the left side of the working chamber is connected with a discharge pipe, and the rotating shaft is nested inside the crushing chamber, the aggregate chamber and the working chamber; a crushing blade is fixedly connected to the outer side of the rotating shaft at the upper end of the crushing chamber, and the lower end of the rotating shaft at the crushing chamber is fixedly connected to a driving column, and a scraping mechanism is arranged on the driving column.

[0004] Construction waste such as waste concrete is usually crushed and then recycled, but construction waste usually also contains metal waste such as steel bars. The metal waste is relatively hard and will cause damage to the recycling equipment when it is recycled and crushed together with waste concrete. Utility Model Content

[0005] In order to protect the recycling equipment and improve the safety of the equipment itself, the present application provides a construction waste safety monitoring and sorting device.

[0006] The present application provides a construction waste safety monitoring and sorting device that adopts the following technical solution:

[0007] A construction waste safety monitoring and sorting device comprises a conveying platform, a conveying belt is arranged on the conveying platform, the conveying belt comprises a non-metallic area and a metal area, a magnetic block is arranged at the bottom of the metal area, a monitoring platform is arranged at the end of the non-metallic area, a monitoring belt whose movement direction is consistent with the conveying direction of the conveyor belt is arranged on the monitoring platform, a metal detector is arranged at one end of the monitoring belt close to the non-metallic area, and a push plate for pushing out discarded materials on the monitoring belt is movably connected to one end of the monitoring belt away from the non-metallic area.

[0008] By adopting the above technical solution, construction waste is dumped onto the conveyor belt. During the conveying process, the metal is adsorbed by the magnetic block to the metal area, and the remaining waste is on the non-metal area and flows to the monitoring station through the non-metal area. The waste falls on the monitoring belt and moves along the monitoring belt to the metal detector. The metal detector performs metal detection on the waste. If metal residue is detected, the push plate starts to push the waste off the monitoring belt to prevent it from falling into the rear recycling equipment. If there is no metal residue, the waste flows to the rear recycling equipment through the monitoring belt. The metal waste in the construction waste is recycled and monitored through the two lines of defense of the metal area and the monitoring station, reducing the amount of waste flowing into the rear recycling equipment, thereby protecting the recycling equipment and improving the stability and safety of the operation of the recycling equipment.

[0009] Preferably, a return belt is provided on the side of the non-metallic zone away from the metal zone, the conveying direction of the return belt is opposite to the conveying direction of the conveyor belt, and the end of the return belt away from the monitoring station is inclinedly provided with a return plate for guiding the discarded materials on the return belt to the non-metallic zone, and the end of the non-metallic zone away from the return plate is opposite to the push plate.

[0010] By adopting the above technical solution, when the metal detector detects residual metal in the discarded materials, the push plate starts to push the discarded materials onto the return belt, and the return belt transports the discarded materials to the head end of the conveyor belt. Under the guidance of the return plate, the discarded materials flow back onto the conveyor belt and are removed again through the metal area and non-metal area until they can pass through the metal detector.

[0011] Preferably, a baffle is provided at one end of the non-metallic zone close to the return belt, and a return port is provided at one end of the baffle away from the monitoring station.

[0012] By adopting the above technical solution, the baffle separates the discarded materials to prevent the discarded materials from flowing to the reflux belt when the discarded materials are transported in the non-metallic area, thereby affecting the transportation efficiency of the discarded materials.

[0013] Preferably, a reflux belt is provided at one end of the metal zone close to the monitoring platform for conveying discarded materials flowing down from the metal zone to the monitoring belt, one end of the reflux belt is located below the metal zone, and the other end is higher than the monitoring belt.

[0014] By adopting the above technical solution, the non-metallic waste materials remaining on the metal area fall down from the end and flow onto the reflux belt when being transported to the end. The reflux belt mixes this part of non-metallic waste materials with the waste materials on the non-metallic area and flows them to the monitoring platform for detection, thereby increasing the recovery amount of non-metallic waste materials.

[0015] Preferably, a metal recovery box is provided below the metal zone, and a scraper for scraping metal waste from the metal zone is provided on the lower surface of the metal zone, the upper end of the scraper contacts the metal zone, and the lower side of the scraper faces the metal recovery box.

[0016] By adopting the above technical solution, the metal waste is adsorbed on the metal area under the action of magnetic force, the non-metal waste falls on the reflux belt for recycling, the metal waste moves with the metal area until the scraper, the scraper removes the metal waste on the metal area, and the metal waste falls into the metal recovery box for recycling.

[0017] Preferably, a magnetic roller is provided above one end of the monitoring platform close to the non-metallic area.

[0018] By adopting the above technical solution, the magnetic roller absorbs and removes the fine metal waste in the waste material flowing into the monitoring belt, reducing the amount flowing into the metal detector, thereby improving the detection efficiency.

[0019] Preferably, a vibration table is provided on the conveying table, and the conveyor belt is arranged on the vibration table.

[0020] By adopting the above technical solution, when the conveyor belt is conveying construction waste, the vibration table vibrates the conveyor belt and the construction waste on the conveyor belt, thereby improving the screening effect of metal waste.

[0021] Preferably, the length of the vibration table is smaller than the length of the conveyor belt, and the four corners of the conveyor belt are connected to the conveying table via buffer elastic feet.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Through the two lines of defense of the metal area and the monitoring station, the metal waste in the construction waste is recycled and monitored to reduce the amount of metal waste flowing into the rear recycling equipment, thereby protecting the recycling equipment and improving the operating stability and safety of the recycling equipment.

[0028] The present application is further described in detail below in conjunction with all the accompanying drawings. Example

[0029] The present application discloses a construction waste safety monitoring and sorting device, referring to Figure 1 to Figure 2 , including a conveying platform 1, a return platform 3 and a monitoring platform 2. Construction waste is dumped on the conveying platform 1, and metal waste and non-metal waste are sorted. Non-metal waste flows to the monitoring platform 2 for detection. If there is no metal residue, it flows to the rear recycling equipment. If metal residue is detected, the waste is sent to the return platform 3, and the return platform 3 returns the waste to the conveying platform 1 for sorting.

[0030] Reference Figure 1 to Figure 2 A vibrating table 14 is provided on the conveying platform 1, and a conveyor belt 11 is provided on the vibrating table 14. The conveyor belt 11 has a head end and a tail end. The length of the conveyor belt 11 is greater than the length of the vibrating table 14, and the four corners of the conveyor belt 11 are connected to the conveying platform 1 through buffer elastic feet 15. The conveyor belt 11 includes a non-metallic area 111 and a metal area 112. A magnetic block 113 is fixed at the bottom of the metal area 112, and the magnetic block 113 can absorb the metal waste in the construction waste through the metal area 112. The construction waste is dumped on the conveyor belt 11, and the conveyor belt 11 vibrates up and down driven by the vibrating table 14, and the magnetic block 113 absorbs the metal waste, thereby realizing the sorting of metal waste and non-metal waste.

[0031] Reference Figure 1 to Figure 2 , the monitoring station 2 is located at the end of the non-metallic area 111. The monitoring station 2 is provided with a monitoring belt 21 whose conveying direction is consistent with that of the conveyor belt 11, and the monitoring station 2 is provided with a metal detector 22 located above the monitoring belt 21, which is used to perform metal detection on the discarded materials flowing into the monitoring belt 21. A magnetic roller 24 is provided at one end of the monitoring station 2 close to the non-metallic area 111, and the magnetic roller 24 is located between the metal detector 22 and the non-metallic area 111. The magnetic roller 24 absorbs the metal discarded materials in the discarded materials flowing into the monitoring belt 21, reduces the content of the metal discarded materials, and facilitates the remaining discarded materials to pass through the metal detector 22 and flow into the rear recycling equipment.

[0032] Reference Figure 1 to Figure 2 A reflow belt 4 is provided at the end of the metal area 112, one end of which is located below the metal area 112, and the other end is higher than the monitoring belt 21 and directly opposite to the end of the monitoring belt 21 close to the non-metal area 111. The non-metal waste on the metal area 112 flows out from the metal end and falls on the reflow belt 4, and under the drive of the reflow belt 4, it flows to the monitoring belt 21 and mixes with the waste on the non-metal area 111, and passes through the magnetic roller 24 and the metal detector 22.

[0033] Reference Figure 1 to Figure 2A metal recovery box 5 is provided below the conveyor platform 1 and is located below the metal area 112. The metal recovery box 5 is located between the head end and the tail end of the metal area 112. A scraper 13 is provided on the conveyor platform 1 and is located on the lower surface of the metal area 112 and is used to scrape off the metal waste on the metal area 112. The upper end of the scraper 13 contacts the metal area 112, and the lower end faces the metal recovery box 5.

[0034] Reference Figure 1 to Figure 2 The discarded materials on the metal area 112 and the non-metal area 111 fall onto the monitoring belt 21 for detection. If there is no metal residue, it continues to flow backward to the recycling equipment. If there is metal residue, it is introduced into the return material table 3.

[0035] Reference Figure 1 to Figure 2 The end of the monitoring platform 2 away from the non-metallic area 111 is slidably connected with a push plate 23, which is connected to the monitoring platform 2 through a cylinder, and the cylinder controls the movement of the push plate 23. The metal detector 22 is electrically connected to the cylinder through a controller. When the metal detector 22 detects metal, the output shaft of the cylinder extends to push the push plate 23 onto the monitoring belt 21, and the push plate 23 pushes the waste material on the monitoring belt 21 off the monitoring belt 21. If there is no metal, the output shaft of the cylinder retracts and drives the push plate 23 to retract, and the push plate 23 is removed from the monitoring belt 21, and the waste material can be transported from the monitoring belt 21 to the end.

[0036] Reference Figure 1 to Figure 2 The return material platform 3 is located on the side of the non-metallic area 111 away from the metal area 112, and one end of the return material platform 3 is flush with the head end of the conveying platform 1, and the other end is flush with the end of the monitoring platform 2. The push plate 23 is tilted on the monitoring belt 21, and the push plate 23 is located on the side of the monitoring belt 21 away from the return material platform 3. When the push plate 23 is located on the monitoring belt 21 to block the waste material on the monitoring belt 21, the waste material will flow to the return material platform 3 along the push plate 23.

[0037] Reference Figure 1 to Figure 2 The return belt 31 is provided on the return platform 3, and the conveying direction of the return belt 31 is opposite to that of the conveying direction of the conveyor belt 11. A return plate 32 is provided at an inclined end of the return belt 31 away from the monitoring platform 2 for guiding the discarded materials on the return belt 31 to the debris area. The discarded materials on the monitoring belt 21 flow onto the return belt 31 under the push of the push plate 23, and the return belt 31 conveys the discarded materials to the return plate 32, and the discarded materials flow back onto the conveyor belt 11 under the guidance of the return plate 32 for sorting.

[0038] Reference Figure 1 to Figure 2 The non-metallic area 111 is provided with a baffle 12 at one end close to the return belt 31, and a return port 121 is provided at one end of the baffle 12 away from the monitoring station 2. The baffle 12 separates the discarded materials to prevent the discarded materials from flowing to the return belt 4 when the non-metallic area 111 is conveying the discarded materials, thereby affecting the conveying efficiency of the discarded materials. The discarded materials on the return belt 31 can flow into the conveyor belt 11 from the return port 121.

[0039] The implementation principle of a construction waste safety monitoring and sorting device in an embodiment of the present application is as follows: an operator pours construction waste onto a conveyor belt 11 for sorting. Metal waste is located in the metal zone 112, and non-metal waste is located in the non-metal zone 111. Driven by the metal zone 112, the metal waste eventually falls into the metal recovery box 5. The non-metal waste falls onto the monitoring belt 21 through the non-metal zone 111 and the return belt 4, and the magnetic roller 24 adsorbs and removes the metal waste again. The remaining waste is detected by a metal detector 22. If there is no metal residue, the remaining waste is discharged from the end of the monitoring belt 21 and flows into the rear recycling equipment. If there is metal residue, the push plate 23 starts to push this part of the waste onto the return belt 31, and the return belt 31 returns this part of the waste to the conveyor belt 11 for sorting.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
