Description

Technical Field

[0001] This utility model is a civil engineering waste treatment device, belonging to the field of civil engineering. Background Technology

[0002] With social development, continuous technological progress, and the continuous improvement of economic levels, urban construction inevitably generates a large amount of construction waste during the current stage of social development. Construction waste refers to the slag, waste soil, waste materials, silt, and other waste generated by construction units or individuals during the construction, laying, demolition, and repair of various buildings, structures, and pipelines. Construction waste refers to the general term for slag, waste concrete, waste bricks, and other waste generated by people in the production activities of demolition, construction, decoration, and repair of the construction industry. These materials do not help the building itself, but the substances generated during the construction process need to be treated accordingly.

[0003] For example, a civil engineering waste recycling and processing device with patent number CN202321665592.X describes a process where civil engineering waste is fed into a recycling bin under gravity. A first motor outputs a transmission mechanism that drives two sets of crushing rollers to rotate, crushing the waste. The crushed waste falls onto the top of a screen plate. Because the screen plate is installed at an angle, some large-diameter waste is discharged from the large waste outlet. Waste meeting the requirements falls into the discharge trough. A second motor outputs a rotating block that rotates, and during rotation, the rotating block drives a push plate via rollers. The reciprocating motion causes the rotating block to reach its maximum diameter. The rotating block then pushes the push plate to discharge the accumulated construction waste from the discharge trough. A shovel at one end of the push plate cleans the inner wall of the discharge trough, scraping off the construction waste adhering to it. A limiting groove restricts the movement of the rollers, preventing them from detaching from the rotating block during rotation. By installing a discharge device driven by a second motor, the crushed construction waste can be pushed through the discharge trough more quickly, improving discharge efficiency and effectively preventing clogging, thereby increasing the processing efficiency of the recycling equipment.

[0004] According to the above description, this patent only uses a single crushing roller to crush the waste material and then filters it to achieve the waste treatment. However, in the single crushing process of civil engineering powder, some waste material does not come into direct contact with the crushing roller during crushing, but is merely squeezed inside the crushed waste. Therefore, no direct crushing work is achieved, which reduces the final treatment effect. Therefore, this utility model proposes a multi-crushing civil engineering waste treatment device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a civil engineering waste treatment device.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A civil engineering waste treatment device includes a primary crushing box and a fine crushing box, which are connected by a discharge bin. The primary crushing box contains two sets of crushing components, and the fine crushing box contains a fine crushing component. An integrated mounting frame is fixed to the outer walls of both the primary and fine crushing boxes. The fine crushing box is circular. The fine crushing component includes a drive motor fixed to one side of the outer wall of the fine crushing box. The output end of the drive motor is connected to a drive rod penetrating the fine crushing box. Multiple grinding plates are fixed to the outer surface of the drive rod. The ends of the grinding plates facing inwards from the fine crushing box are arc-shaped and contact the inner wall of the fine crushing box. An arc-shaped frame is installed on the bottom surface of the fine crushing box, and through holes are evenly distributed on the arc-shaped frame. Furthermore, two arc-shaped fixing plates are fixedly installed on the fine grinding box, and the arc-shaped fixing plates are fixedly connected to the fixing frame. An integrated end connecting plate is also fixedly installed between the fine grinding box and the fixing frame.

[0007] Furthermore, a bearing is connected to the end of the drive rod that passes through the fine grinding chamber, and the bearing is fixed to the outer wall of the fine grinding chamber.

[0008] Furthermore, each set of crushing components includes two crushing rollers, with both ends of each crushing roller extending out of the primary crushing box. One end of each roller is connected to a gear, and the gears mesh sequentially through an even number of auxiliary gears. The other end of one crushing roller in each set is connected to an auxiliary drive motor, which is mounted on the outer wall of the primary crushing box.

[0009] Furthermore, multiple mounting plates are fixed at both ends of the arc-shaped frame, and an arc-shaped mounting groove is provided at the bottom of the fine crushing box.

[0010] Furthermore, the arc-shaped frame is embedded in the arc-shaped mounting groove, and matching threaded holes are provided on both the mounting plate and the fine crushing box.

[0011] Furthermore, an integrated collection box is fixedly installed at the bottom of the fine crushing box, and a conical discharge port is fixedly installed at the bottom of the collection box. A feeding hopper is installed on the preliminary crushing box, and a hinged flip cover is installed on the feeding hopper.

[0012] Furthermore, both sides of the collection box are equipped with boxes and doors, which correspond to the two ends of the grinding plate. Each box door is equipped with abutting components, which include multiple threaded rods that spirally penetrate the box door. One end of each threaded rod is fixed with a manual turntable, and the inner side of the box door is connected to abutting plates in conjunction with a telescopic rod.

[0013] The beneficial effects of this utility model are: The construction waste is processed in two ways: a preliminary crushing box and a fine crushing box. The preliminary crushing box has two sets of crushing components for initial fine processing. After the construction waste is crushed, it is discharged into the fine crushing box through the discharge hopper for final fine processing.

[0014] The drive motor activates the drive rod, which in turn activates the grinding plate to rotate. The arc-shaped end of the grinding plate contacts the inner wall of the fine crushing box, which stores construction waste. When the grinding plate rotates, it can crush the waste in the fine crushing box. The grinding plate can also drive the waste to rotate, improving the waste processing effect. The crushed waste that meets the standard passes through the through holes on the surface of the arc-shaped frame for final processing and discharge.

[0015] By employing a dual processing method, avoiding the single crushing process, this invention ensures proper treatment of waste materials before final discharge, thereby improving the treatment effect of civil engineering waste and guaranteeing the recycling and reuse of waste materials from subsequent civil engineering processes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a civil engineering waste treatment device, including a preliminary crushing box 1 and a fine crushing box 2. The preliminary crushing box 1 and the fine crushing box 2 are connected by a discharge bin 3. The preliminary crushing box 1 is equipped with two sets of crushing components, and the fine crushing box 2 is equipped with a fine crushing component. An integrated fixing frame 4 is fixed on the outer wall of the preliminary crushing box 1 and the fine crushing box 2. The fine crushing box 2 is a circular box. The fine crushing component includes a drive motor 6 fixed on one side of the outer wall of the fine crushing box 2. The output end of the drive motor 6 is connected to a drive rod 7 that penetrates the fine crushing box 2. Multiple grinding plates 8 are fixed on the outer surface of the drive rod 7. The end of the grinding plate 8 facing the inside of the fine crushing box 2 is an arc-shaped end. The arc-shaped end of the grinding plate 8 is in contact with the inner wall of the fine crushing box 2. An arc-shaped frame 10 is installed on the bottom surface of the fine crushing box 2. Through holes 11 are evenly distributed on the arc-shaped frame 10.

[0021] See Figure 1 and Figure 4 Two arc-shaped fixing plates 12 are fixedly installed on the fine grinding box 2. The arc-shaped fixing plates 12 are fixedly connected to the fixing frame 4. An integrated end connecting plate 13 is also fixed between the fine grinding box 2 and the fixing frame 4. The setting of the arc-shaped fixing plates 12 and the end connecting plates 13 ensures better fixing effect of the fine grinding box 2 and more stable internal operation.

[0022] See Figure 2 The drive rod 7 passes through the end of the fine grinding box 2 and is connected to a bearing. The bearing is fixed on the outer wall of the fine grinding box 2. The bearing ensures that the drive rod 7 is driven more stably.

[0023] See Figure 1 and Figure 4 Each crushing assembly includes two crushing rollers 14. Both ends of each crushing roller 14 extend out of the primary crushing box 1, and one end of each roller is connected to a gear 15. The gears 15 mesh sequentially with each other through an even number of auxiliary gears. The other end of one crushing roller 14 in each assembly is connected to an auxiliary drive motor 16, which is mounted on the outer wall of the primary crushing box 1. The auxiliary drive motor 16 drives one crushing roller 14 in each assembly to rotate. The other end of each crushing roller 14 meshes with the gear 15 and auxiliary gears to drive the two crushing rollers 14 in each assembly to rotate in opposite directions. This enables the crushing assembly to process waste materials. The auxiliary gears are equipped with bearings arranged on the outer wall of the primary crushing box 1. Bearings are also provided on the ends of the crushing rollers 14 that are not connected to the gear 15 and auxiliary drive motor. These bearings and the bearings on the auxiliary gears are both located on the outer wall of the primary crushing box 1. The bearings are not shown in the figure. The purpose of the bearings is to ensure the rotational stability of the crushing rollers 14 and auxiliary gears. These are all conventional settings.

[0024] See Figure 3 Multiple mounting pieces 17 are fixedly provided at both ends of the arc-shaped frame 10. An arc-shaped mounting groove 18 is provided at the bottom of the fine grinding box 2. The arc-shaped frame 10 is embedded in the arc-shaped mounting groove 18. Matching threaded holes 19 are provided on both the mounting pieces 17 and the fine grinding box 2. When the arc-shaped frame 10 is embedded in the arc-shaped mounting groove 18, the mounting pieces 17 are equipped with screws that are screwed into the threaded holes 19 on the mounting pieces 17 and the fine grinding box 2 to fix the arc-shaped frame 10. It is also convenient to disassemble the arc-shaped frame 10 afterward. It is also convenient to clean the arc-shaped frame 10 when it is damaged.

[0025] See Figure 1 and Figure 5 The fine grinding box 2 has an integrated collection box 20 fixed at its bottom. The bottom of the collection box 20 has a conical discharge port 21 fixed at its bottom. The preliminary grinding box 1 has a feed hopper 22 with a hinged flip cover. Both sides of the collection box 20 have doors 23, which correspond to the two ends of the grinding plate 8. Each door 23 has a mating assembly, which includes multiple threaded rods 24 spirally penetrating the door 23. One end of each threaded rod 24 is fixed with a manual turntable. The inner side of the door 23 is connected to a mating plate 25 with a telescopic rod. The final crushed waste is discharged through the conical discharge port 21 of the collection box 20 for collection. Opening the two boxes 23 exposes the end of the arc frame 10 with the mounting plate 17. Using tools, the screws of the mounting plate 17 can be removed to disassemble and take out the arc frame 10. After installing the arc frame 10, close the boxes 23. Locks are provided on the boxes 23 and the collection box 20. The locks are existing devices used to lock the boxes. The locks are varied and will not be described in detail here. After closing the boxes 23, the manual turntable can be manually rotated to rotate the connected threaded rod 24. The threaded rod 24 rotates forward and slowly contacts the abutment plate 25, moving the abutment plate 25 towards the mounting plate 17. Finally, the abutment plate 25 abuts the mounting plate 17 and the screws installed on the mounting plate 17, ensuring that the arc frame 10 is further fixed after installation. The setting of the threaded rod 24 and the abutment plate 25 does not affect the disassembly and installation of the arc frame 10.

[0026] In use, the civil engineering waste is processed in two ways: a preliminary crushing box 1 and a fine crushing box 2. The preliminary crushing box 1, equipped with two sets of crushing components, performs initial fine crushing. After crushing, the waste is discharged into the fine crushing box 2 via the discharge bin 3 for final fine crushing. The drive motor 6 activates the drive rod 7, which in turn activates the grinding plate 8, causing it to rotate. The arc-shaped end of the grinding plate 8 contacts the inner wall of the fine crushing box 2, which contains the civil engineering waste. The rotation of the grinding plate 8 crushes the waste within the fine crushing box 2 and also drives the waste to rotate, improving the processing efficiency. The crushed waste passes through the through-holes 11 on the surface of the arc-shaped frame 10 for final discharge. This dual processing method avoids the need for single-stage crushing. This invention ensures thorough waste processing before final discharge, improving the overall civil engineering waste treatment efficiency and guaranteeing the recycling and reuse of waste from subsequent civil engineering projects.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
