Description

Technical Field

[0001] The utility model relates to the field of construction waste treatment, in particular to a device for removing light substances in construction waste. Background Technique

[0002] Construction waste refers to the waste generated during the construction, demolition, etc. of various buildings and structures. Construction waste often contains many recyclable materials. A pneumatic separation device is often used to separate the light impurities in construction waste to achieve maximum resource recovery and utilization.

[0003] Since construction waste often contains a large amount of light substances such as wooden blocks and sawdust, it is necessary to remove these light substances during the treatment of construction waste for easy classification and utilization. At present, the light substances in construction waste are mainly separated from the heavy substances by means of air blowing using the mass difference. Due to the different sizes of construction waste, during the pneumatic separation process, construction waste with the same or similar mass is likely to be mixed together and difficult to separate, resulting in a poor removal effect on light construction waste. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for removing light substances in construction waste to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

When the toothed ring rotates, it can drive the sieve drum and the spiral conveyor blade to rotate. When the spiral conveyor blade rotates, it can gradually convey the construction waste inside the sieve drum to one side of the sieve drum. During the conveying process, since the inner diameter of the sieve holes gradually increases from one side to the other side, the sieve holes can gradually screen the crushed construction waste from small to large and fall on the corresponding belt conveyor for conveying.

Through the separation of the separation plates, the light wood chips in the same-volume construction waste can be effectively separated and screened out, effectively improving the separation effect of the light substances in the construction waste.

[0023] The technical solution of this patent will be further described in detail below in conjunction with the specific implementation mode

[0024] Please refer to Figures 1-5 , the device for removing light substances from construction waste, including a screening mechanism 1, the screening mechanism 1 includes a U-shaped box 101, one side inside the U-shaped box 101 is penetrated by a screening cylinder 103, the screening cylinder 103 is rotatably connected to the U-shaped box 101, and a spiral conveyor blade 105 is fixedly connected inside the screening cylinder 103. The setting of the spiral conveyor blade 105 can convey the construction waste inside the screening cylinder 103 during rotation. A plurality of screening holes 104 are evenly opened on the surface of the screening cylinder 103. The setting of the screening holes 104 can screen the construction waste inside the screening cylinder 103. The inner diameters of each group of screening holes 104 gradually decrease from one side to the other side, so that during the process of conveying the construction waste to one side, the screening holes 104 can gradually screen out the construction waste from small to large by volume

[0025] On one side of the U-shaped box 101, there is a hopper 106. The output end of the hopper 106 extends into the interior of the sieve cylinder 103. The hopper 106 is arranged to hold construction waste and guide it into the interior of the sieve cylinder 103. At the four corners of the hopper 106, there are support columns 107 fixedly connected. The support columns 107 can support the hopper 106. On the outer side of the sieve cylinder 103, there is a toothed ring 109 fixedly connected. At the bottom of the toothed ring 109, there is a gear 111 meshed. On the outer side of the support column 107, there is a support plate 108 fixedly connected. The output end of the support plate 108 is fixedly connected to the gear 111. Each group of partition plates 102 is rotatably connected to the sieve cylinder 103. The motor 110 is arranged to drive the gear 111 and the toothed ring 109 to rotate when starting to work, so as to drive the sieve cylinder 103 to rotate accordingly. Separation mechanism 2, the separation mechanism 2 includes belt conveyors 201 evenly arranged inside the U-shaped box 101. On the inner top wall of the U-shaped box 101, there are multiple partition plates 102 fixedly connected evenly. The partition plates 102 are arranged to divide the interior of the U-shaped box 101 into multiple chambers for separating construction waste of different volumes screened out.

[0026] Each group of belt conveyors 201 is fixedly connected to the partition plate 102. The belt conveyors 201 are located below the sieve cylinder 103. The belt conveyors 201 are arranged to catch the construction waste screened out and convey the screened out construction waste when starting to work. At the bottom of each group of belt conveyors 201, there is a blower 209 fixedly connected. The blower 209 is arranged to blow out air flow when starting to work, so that when the construction waste of the same volume falls from the belt conveyor 201, under the action of the air flow, the light construction waste such as wood chips in the construction waste can be blown to a position farther away, while the construction waste with heavier concrete blocks and stones falls to a position closer. On one side of the bottom of each group of belt conveyors 201, there is a separation plate 202 detachably connected. The separation plate 202 is arranged to separate the light construction waste and the heavy construction waste. On both sides of the separation plate 202, there are guide tables 203 symmetrically fixedly connected. The bottom of each group of guide tables 203 is in contact with the inner wall of the U-shaped box 101. The guide tables 203 are arranged to guide the separated construction waste, so as to facilitate the discharge of the construction waste.

[0027] Guide strips 206 are symmetrically and fixedly connected to both the inner wall of the U-shaped box 101 and both sides of each group of partition plates 102. Guide plates 204 are symmetrically and fixedly connected to both the inner wall of the U-shaped box 101 and both sides of each group of partition plates 102. Each group of guide plates 204 is respectively located above each group of guide grooves 208. The arrangement of the guide plates 204 can block the top of the guide strips 206 to reduce the probability of construction waste accumulating on the top of the guide strips 206. Symmetrically and fixedly connected to the bottom of the guide plate 204 are diagonal braces 205. The end of the diagonal brace 205 away from the guide plate 204 is fixedly connected to the partition plate 102. The arrangement of the diagonal braces 205 can further support the guide plate 204, thereby improving the installation stability of the guide plate 204. Guide grooves 208 adapted to the guide strips 206 are symmetrically formed on both sides of each group of separation plates 202. The separation plates 202 are slidably connected to the guide strips 206. The arrangement of the guide strips 206 and the tightening bolts 207 can facilitate the adjustment of the position of the separation plates 202, thereby realizing the adjustment of the separation position of the light construction waste and the heavy construction waste. Symmetrically and threadedly connected to the top of the separation plate 202 are tightening bolts 207. The tightening bolts 207 are in contact with the guide strips 206. The arrangement of the tightening bolts 207 is used to limit and fix the separation plates 202 when tightened against the guide strips 206.

[0028] In this embodiment, the belt conveyor 201 is prior art and will not be elaborated here.

[0029] During use, start the motor 110, each group of belt conveyors 201 and each group of blowers 209, so that when the motor 110 starts to work, it can drive the sieve drum 103 and the spiral conveyor blades 105 to rotate through the transmission of the gear 111 and the toothed ring 109. Then pour a large amount of crushed construction waste into the hopper 106, so that the crushed construction waste can be discharged into one side of the sieve drum 103. When the spiral conveyor blades 105 rotate, they can convey the crushed construction waste. During the conveying process, since the inner diameter of the sieve holes 104 gradually increases from one side to the other side, the sieve holes 104 can gradually screen the crushed construction waste from small to large and fall on the corresponding belt conveyors 201, so that each group of belt conveyors 201 can convey the construction waste of corresponding sizes to one side. When the construction waste falls from one end of the belt conveyor 201, under the action of the wind blown by the blower 209 during operation, the relatively light wood chips in the construction waste can be blown and fall farther, while the relatively heavy concrete blocks or stones fall closer. Through the separation of the separation plates 202, the light wood chips in the same volume of construction waste can be effectively separated and screened out, thereby effectively improving the separation effect of the light substances in the construction waste.
