Description

Technical Field

[0001] This utility model belongs to the field of construction waste treatment technology, and in particular relates to a construction waste recycling and treatment device. Background Technology

[0002] With the acceleration of urbanization and the rapid development of the construction industry, a large amount of construction waste, mainly including bricks, sand and gravel, has been generated. However, the open-air dumping or landfilling methods not only occupy land resources but also cause environmental pollution, such as dust, and the transportation and disposal costs are high, which brings an economic burden to society.

[0003] Currently, construction waste is not without value; it possesses enormous potential for recycling and reuse. In recent years, with the increasing awareness of environmental protection and the advancement of technology, some technologies and devices for the reuse and processing of construction waste have emerged. For example, patent CN206415411U discloses a construction waste recycling and processing device. This device, through a structure including a drive motor, a crushing box, a feed inlet, and multiple bases, achieves the crushing and processing of construction waste. Its unique base design includes components such as a support frame, a piston rod housing, a piston rod, and shock-absorbing springs, effectively reducing the rigid vibration of the machine body, avoiding damage to the ground, and ensuring the uniformity of crushing. During operation, the device also prevents waste from being ejected, ensuring operational safety.

[0004] Although the aforementioned construction waste recycling and processing device can realize the processing and reuse of construction waste, during the processing of construction waste, because construction waste contains a large number of fine particles and dust, these substances are easily raised and dispersed into the air during the crushing process, causing the deterioration of the processing environment, threatening the health of operators, and also increasing the difficulty and cost of subsequent dust removal.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This utility model embodiment provides a construction waste recycling and processing device, such as... Figure 1-4As shown, the construction waste recycling and processing device includes: a base plate 20, on which a crushing box 1 is fixedly installed for crushing and processing construction waste for recycling; a spiral crushing roller 2 and a rotating rod 3, both of which are rotatably installed inside the crushing box 1. The adjacent ends of the spiral crushing roller 2 and the rotating rod 3 are fixedly connected by a coupling. The spiral crushing roller 2 is used for preliminary crushing of construction waste, and multiple crushing blades 4 are fixedly installed on the rotating rod 3 for further crushing of construction waste; and an atomizing nozzle 9, which is fixedly installed on the top of the crushing box 1, with its water outlet extending into the crushing box 1 for spraying... Water for dust suppression; a water tank 10, which is located on one side of the crushing box 1 and is used to hold water for dust suppression; a water pump 11, which is fixedly installed on the water tank 10 and is used to pump the water for dust suppression. The water outlet of the water pump 11 is fixedly connected to the atomizing spray pipe 9 through the water outlet pipe 13, and a water inlet pipe 12 is fixedly connected to the water inlet of the water pump 11. The water inlet of the water inlet pipe 12 extends into the water tank 10; a drive mechanism, which is located on the base plate 20 and is used to drive the rotating rod 3 and the spiral crushing roller 2 to rotate; and a discharge mechanism, which is located on the crushing box 1 and is used to discharge the crushed construction waste at a uniform speed.

[0025] In this embodiment, the base plate 20 serves as the supporting foundation for the entire device, providing a stable mounting platform for the crushing box 1 and other components subsequently installed on it. This ensures the stability of the entire device during operation and prevents the crushing and other processing steps from being affected by device shaking. The crushing box 1 provides a relatively enclosed space for crushing construction waste, allowing the crushing process to be concentrated inside the box, facilitating control of the crushing situation. It also facilitates the implementation of subsequent dust suppression and other treatment measures, preventing waste and dust from scattering everywhere. The spiral crushing roller 2 is used for preliminary crushing of construction waste, and multiple crushing blades 4 are fixedly installed on the rotating rod 3 for... Further crushing of construction waste; through a reasonable rotational installation method and coupling connection, the spiral crushing roller 2 and the rotating rod 3 can work together to achieve continuous crushing of construction waste; the initial crushing of the spiral crushing roller 2 can break down larger pieces of construction waste into smaller sizes, making it easier for the crushing blades 4 on the rotating rod 3 to perform finer further crushing. This two-stage crushing design can more effectively crush construction waste into suitable particle sizes, improve the crushing effect, and prepare for subsequent reuse; an atomizing spray pipe 9 is installed at the top of the crushing box 1 to spray water into the box in a timely manner during the crushing process, atomizing the fine particles that are raised. The process wets particles and dust, increasing their weight and making them less likely to disperse into the air. This effectively solves the problem of dust dispersion generated during the crushing process in existing construction waste treatment devices, improves the processing environment, protects the health of operators, and reduces the difficulty and cost of subsequent dust removal. The water tank 10 provides a water source for dust suppression, ensuring sufficient water for the atomizing nozzle 9 to spray water for dust suppression throughout the entire crushing process, guaranteeing the continuous and effective implementation of dust suppression measures. The water pump 11 pumps water from the water tank 10 to the atomizing nozzle 9, achieving water recycling and ensuring the atomizing nozzle 9 can continuously generate water. The system continuously sprays atomized water to suppress dust and maintain a good dust suppression effect. The drive mechanism provides power for the rotation of the spiral crushing roller 2 and the rotating rod 3, enabling them to work at the set speed and mode, thereby ensuring that the construction waste can be crushed smoothly. It is the key power source for the normal operation of the entire crushing process. The discharge mechanism can discharge the crushed construction waste evenly from the crushing box 1 at a certain speed. On the one hand, it facilitates the subsequent collection and reuse of the crushed waste. On the other hand, it avoids problems such as affecting the crushing effect or causing blockage in the crushing box 1 due to discharge being too fast or too slow, thus ensuring the stable operation of the entire device.

[0026] In a further preferred embodiment of this utility model, the driving mechanism includes: a bracket 5 fixed to the bottom of the crushing box 1, a transmission rod 6 rotatably mounted on the bracket 5, the top end of the transmission rod 6 being connected to the bottom end of the rotating rod 3 via a coupling; a reducer 7 fixedly mounted on the base plate 20, the output shaft of the reducer 7 being fixedly connected to the bottom end of the rotating rod 3 via a coupling; and a motor 8 fixedly mounted on the base plate 20, the output shaft of the motor 8 being fixedly connected to the input shaft of the reducer 7 via a coupling.

[0027] In this embodiment, the bracket 5 provides a stable and reliable mounting support point for the transmission rod 6, ensuring the positional accuracy and stability of the transmission rod 6 during operation. This allows power to be smoothly transmitted from the transmission rod 6 to the rotating rod 3, avoiding problems such as shaking and offset during power transmission due to unstable installation, thus ensuring the normal operation of the entire crushing device. The transmission rod 6, as an intermediate transmission component connecting the reducer 7 and the rotating rod 3, effectively transmits the power output from the reducer 7 to the rotating rod 3, enabling the rotating rod 3 to obtain appropriate speed and torque to drive the spiral crushing roller 2 to work together to crush construction waste. The connection of the transmission rod 6 allows for flexible adjustment of the power transmission path and method, facilitating optimization in device layout and design, and also enabling adaptive transmission and distribution of power according to actual needs. The reducer 7 plays a crucial role in reducing the output speed of the motor 8 and increasing the torque. During the crushing process of construction waste, different crushing stages and waste characteristics may require different speeds and torques to ensure crushing effects and normal equipment operation. The reducer 7 can reduce the high speed of the motor 8 to a suitable operating speed range for the rotor 3 and the spiral crushing roller 2 according to actual needs, and correspondingly increase the torque, so that the crushing device can crush construction waste more stably and efficiently, avoiding problems such as insufficient crushing and equipment overload caused by excessive speed or insufficient torque. The motor 8, as the power source of the entire drive mechanism, provides continuous and stable rotational power to the crushing device. In cooperation with the reducer 7, the output power parameters can be flexibly adjusted according to actual working conditions and design requirements to meet the different power needs in the crushing process of construction waste, ensuring that the spiral crushing roller 2 and the rotor 3 can effectively crush construction waste according to the predetermined working mode, thereby realizing the reuse of construction waste.

[0028] In a further preferred embodiment of this utility model, the discharge mechanism includes: a guide hopper 14 fixedly installed at the discharge port of the crushing box 1; a conveying cylinder 15 fixedly installed at the discharge end of the guide hopper 14 to provide a channel for guiding crushed construction waste and prevent waste from splashing; a spiral rod 16 rotatably installed inside the conveying cylinder 15 for guiding the crushed construction waste; and a first bevel tooth 17 and a second bevel tooth 18 respectively fixedly installed on the shaft of the spiral rod 16 and on the transmission rod 6, wherein the first bevel tooth 17 and the second bevel tooth 18 mesh with each other to drive the spiral rod 16 to rotate.

[0029] In this embodiment, the guide hopper 14 serves as a transitional connection, smoothly guiding the crushed construction waste in the crushing box 1 to the subsequent conveying cylinder 15. Its design at the discharge port effectively collects the waste discharged from the crushing box 1, preventing it from scattering due to lack of guidance at the moment of discharge, ensuring that the waste enters the next conveying process in a predetermined direction, maintaining the orderliness of the discharge process. The conveying cylinder 15, on the one hand, serves as the outer shell connecting the guide hopper 14 and the internal screw rod 16, providing a relatively closed and stable conveying channel for the crushed construction waste. This ensures a clear path for the waste during transport, effectively preventing it from splashing out due to lack of restraint, and guaranteeing a clean and safe working environment. On the other hand, its fixed installation ensures the stability of the entire conveying structure, facilitating the continuous and stable completion of the waste conveying task. The screw rod 16, through its rotational motion, propels the crushed construction waste within the conveying cylinder 15 forward in a spiral motion, achieving uniform and orderly conveying of the waste. This conveying method is more stable than other simple pushing methods, effectively avoiding problems such as waste blockage caused by sudden impact or irregular pushing. It ensures that the waste can be smoothly conveyed from the crushing box 1 through the guide hopper 14 and then through the conveying cylinder 15, facilitating further processing or collection of the crushed waste. The meshing transmission of the first bevel gear 17 and the second bevel gear 18 cleverly utilizes the rotational power originally present in the drive mechanism of the transmission rod 6. When the transmission rod 6 rotates, the meshing action of the second bevel gear 18 and the first bevel gear 17 can stably and effectively transmit power to the screw rod 16, giving it a power source for rotation. This drives the screw rod 16 to rotate according to the set speed and direction, realizing the function of guiding the crushed construction waste.

[0030] In a further preferred embodiment of the present invention, a feed hopper 21 is fixedly installed at the feed inlet of the crushing box 1, and a water supply pipe 19 is fixedly connected to the water tank 10 for connecting a water supply device to replenish water into the water tank 10.

[0031] In this embodiment, the wide opening of the feed hopper 21 facilitates the reception of large quantities of construction waste, effectively guiding it smoothly into the crushing chamber 1 and preventing waste from scattering during the feeding process. Simultaneously, the feed hopper 21 serves as a preliminary gathering and guiding mechanism, allowing the construction waste to enter the crushing area more concentratedly and orderly, improving feeding efficiency and accuracy, ensuring the continuous and stable operation of the entire crushing process, and facilitating efficient subsequent crushing operations. As the atomizing nozzle 9 continuously sprays water to suppress dust, the water volume in the water tank 10 gradually decreases. The water replenishment pipe 19 allows for convenient connection to external water supply equipment, such as water pipes or pumps, to replenish the water tank 10 in a timely manner, ensuring that the water tank 10 always has sufficient water for the dust suppression operation of the atomizing nozzle 9. This design guarantees the continuous effectiveness of the dust suppression system, effectively controlling dust dispersion throughout the entire construction waste crushing process, maintaining a good processing environment, protecting the health of operators, and reducing the difficulty and cost of subsequent dust removal.

[0032] In a further preferred embodiment of the present invention, a protective shell 22 is fixedly installed on the base plate 20. The protective shell 22 is used to shield the bracket 5, the transmission rod 6, the reducer 7, the first bevel gear 17 and the second bevel gear 18.

[0033] In this embodiment, the protective shell 22 can prevent operators from accidentally contacting moving parts such as the high-speed rotating transmission rod 6, avoiding personal injury accidents caused by accidental contact and improving the safety of device operation.

[0034] In a further preferred embodiment of the present invention, a plurality of support legs are symmetrically fixedly installed on the bottom of the base plate 20, and shock-absorbing pads are fixedly installed on the bottom end of the support legs.

[0035] In this embodiment, the support legs provide a stable support structure for the entire construction waste recycling and processing device. By symmetrically arranging multiple support legs at the bottom of the base plate 20, the weight of the device can be evenly distributed, ensuring that the device remains stable during placement and operation, preventing tipping or shaking due to an unstable center of gravity. This ensures that the internal components of the device, such as the crushing box and transmission mechanism, can work normally without being disturbed by the instability of the device. The shock-absorbing pads mainly play a role in shock absorption and buffering. The shock-absorbing pads can effectively absorb and buffer vibrations, reduce the transmission of vibrations to the ground, and make the device operate more smoothly.

[0036] In a further preferred embodiment of the present invention, a support column is fixedly installed on the top of the base plate 20, and the top of the support column is fixedly connected to the conveying cylinder 15 for support and reinforcement.

[0037] In this embodiment, during the operation of the construction waste recycling and processing device, the conveying cylinder 15, as an important component of the discharge mechanism, undertakes the task of guiding and crushing construction waste. When the screw rod 16 rotates and pushes the waste inside the conveying cylinder 15, it may generate certain vibrations and stress. The support column firmly connects the base plate 20 and the conveying cylinder 15, providing additional support points for the conveying cylinder 15, effectively enhancing the structural stability of the conveying cylinder 15, enabling it to better withstand various forces generated during the discharge process, preventing the conveying cylinder 15 from deforming, shaking, or even being damaged due to uneven or excessive stress, and ensuring that the discharge operation can be carried out continuously and stably.

[0038] In a further preferred embodiment of the present invention, a detachable inspection plate is provided on the protective shell 22, and the inspection plate is fixedly connected to the protective shell 22 by screws.

[0039] In this embodiment, although the protective shell 22 serves to protect internal components from external interference and prevent personnel from accidentally contacting moving parts, the detachable inspection plate provides a convenient passage when components such as the bracket 5, transmission rod 6, reducer 7, first bevel gear 17, and second bevel gear 18 inside the device need to be inspected, maintained, debugged, or troubleshooted. Workers can easily remove the inspection plate by simply unscrewing the screws and directly access the relevant components inside the protective shell 22 without having to remove the entire protective shell 22, which greatly saves inspection time and workload and improves the efficiency of equipment maintenance.

[0040] In summary, the spiral crushing roller 2 performs initial crushing, breaking large pieces of construction waste into smaller pieces. Then, the rotating rod 3 and its crushing blades 4 further refine the crushing. This two-stage crushing effectively pulverizes the construction waste into suitable particle sizes, improving the crushing effect and laying a good foundation for subsequent reuse. Simultaneously, the drive mechanism provides stable power for crushing, ensuring the smooth operation of the crushing process. The reducer 7 can adjust the speed and torque according to actual needs, avoiding poor crushing or equipment overload due to speed or torque issues. The atomizing nozzle 9, located at the top of the crushing chamber 1, sprays water into the chamber during crushing, moistening the fine particles and dust that are stirred up, preventing them from dispersing. The water tank 10 stores water. The water pump 11 realizes the circulation and transportation of water, ensuring continuous and effective dust suppression, effectively solving the problem of dust dispersion, improving the processing environment, protecting the health of operators, and reducing the difficulty and cost of subsequent dust removal. The guide hopper 14 in the discharge mechanism guides the crushed waste into the conveying cylinder 15 to prevent the discharge from scattering. The conveying cylinder 15 provides a stable and closed conveying channel to prevent waste from splashing and ensure the stability of the conveying structure. The screw rod 16 conveys the waste at a uniform speed and in an orderly manner in a spiral propulsion manner to avoid blockage. Moreover, the screw rod 16 is driven to rotate by the power of the transmission rod 6 through the first conical tooth 17 and the second conical tooth 18 to achieve stable discharge, which facilitates the subsequent collection and further processing of the crushed waste.
