Description

Technical Field

[0001] This utility model belongs to the field of building decoration and environmental protection technology, specifically a waste treatment device for building decoration projects. Background Technology

[0002] In building decoration and renovation projects, a large amount of waste is inevitably generated during construction, including discarded building materials, packaging materials, scraps, and dust produced during construction. If this waste is not disposed of in a timely and effective manner, it will not only occupy a large amount of space but also pollute the environment, affecting the living and working environment of the construction area and its surroundings. Therefore, how to efficiently and environmentally manage waste from building decoration and renovation projects has become one of the key issues of concern in the industry.

[0003] Currently, there is a limited variety of equipment available for processing waste from construction and decoration projects, and existing equipment generally suffers from problems such as limited functionality, low processing efficiency, and complex operation. For example, some equipment can only perform simple crushing or compression functions and cannot classify different types of waste; others, while possessing some classification capabilities, are complex in structure and bulky, making them unsuitable for the confined spaces of construction sites. Furthermore, existing equipment often generates significant noise and dust pollution during operation, further exacerbating the negative environmental impact. Simultaneously, due to the lack of intelligent control mechanisms, existing equipment struggles to flexibly adjust to the type and quantity of waste, resulting in resource waste and ineffective treatment.

[0004] In summary, existing waste treatment equipment for building decoration and renovation projects has significant shortcomings in terms of functionality, adaptability, and environmental protection. There is an urgent need for a new type of equipment that can efficiently treat various types of waste, adapt to the needs of construction sites, and effectively reduce environmental pollution, in order to meet the actual needs of industry development. Utility Model Content

[0005] This utility model belongs to the field of building decoration engineering, and in particular relates to a waste treatment device for building decoration engineering.

[0006] In construction and decoration projects, a large amount of solid waste is generated during construction, such as sawdust, plasterboard fragments, and plastic packaging materials. This waste typically needs to be sorted, crushed, and screened before it can be recycled or properly disposed of. However, existing waste treatment equipment often uses only single crushing and screening methods, which can easily lead to screen clogging or low equipment efficiency due to the variety of materials. Furthermore, existing equipment is cumbersome to clean and maintain, and cannot achieve efficient separation of waste of different particle sizes, affecting the overall treatment effect.

[0007] The purpose of this utility model embodiment is to provide a waste treatment device for building decoration and renovation projects, which aims to solve the problems mentioned in the background art.

[0008] This utility model embodiment is implemented as follows: a waste treatment device for building decoration and renovation projects includes a base, a drive housing is provided on one side of the top of the base, and further includes:

[0009] The processing box has an open structure at both the top and bottom. A support plate is fixedly installed on the other side of the top of the base. A slide rail frame is fixed between the drive box and the support plate at intervals. The processing box is located between the slide rail frames. The output end of the drive box is an eccentric wheel structure connected to the processing box. The drive box is used to drive the processing box to move back and forth on the slide rail frame through the eccentric wheel structure. An inclined guide chute is fixedly connected to the base. The guide chute is located at the bottom of the processing box.

[0010] A separation assembly is located inside a processing chamber. The separation assembly includes a sorting disc rotatably disposed inside the processing chamber.

The two arc-shaped baffles are spaced apart along the axial direction of the sorting disc and fixedly connected to the inner walls of both sides of the processing chamber. The two inclined baffles are spaced apart along the radial direction of the sorting disc and fixedly connected to the inner walls of both sides of the processing chamber. The height of both the arc-shaped baffles and the inclined baffles is greater than the height of the axis of the sorting disc. Both the arc-shaped baffles and the inclined baffles cooperate with the surface of the sorting disc. The arc-shaped baffles, the inclined baffles, the top surface of the sorting disc, and the inner wall of the processing chamber constitute a sorting chamber.

[0011] Both sides of the processing box are equipped with main rollers that cooperate with two slide rail frames. The main rollers are equipped with pawl mechanisms with one-way transmission function. The main rollers and the sorting disc are connected by a gearbox fixedly set on the outer surface of the processing box.

[0012] Preferably, a secondary housing is fixedly connected to the side of the processing housing away from the drive housing, and secondary rollers that cooperate with the slide rail frame are rotatably arranged on both sides of the secondary housing. The secondary housing, secondary rollers, main rollers and sorting disc are all in the same plane.

[0013] Preferably, a rectangular groove is provided at the joint between the processing box and the sub-box. A vertically arranged guide rod is fixedly connected inside the sub-box, and a horizontally arranged push rod is slidably connected to the guide rod. A scraper is fixedly connected to one end of the push rod facing the rectangular groove. The scraper is provided with flexible bristles. A connecting rod is connected to the other end of the push rod. Pins are fixedly connected to both ends of the connecting rod. Cams that are connected to the sub-roller are provided on both sides of the sub-box. The cams are provided with arc-shaped grooves that cooperate with the pins. When the processing box moves back and forth, the cooperation between the cam and the pin causes the scraper at one end of the push rod to move back and forth, so that it contacts the surface of the sorting disc.

[0014] Preferably, an elastic sealing layer is fixedly connected to the push rod, and the elastic sealing layer is sealed to the inner wall of the sub-box. The elastic sealing layer is located between the guide rod and the scraper. The elastic sealing layer isolates the internal space of the sub-box into a closed chamber, and the connecting rod frame and the cam are both located in the closed chamber.

[0015] Preferably, airflow channels are provided inside the scraper and push rod. Multiple air jet holes are provided on the side of the flexible bristles on the scraper. An exhaust pipe connected to the airflow channels is fixedly connected to the connecting rod frame. An air inlet pipe is fixedly provided on the top of the auxiliary housing.

[0018] The waste treatment equipment for building decoration and renovation projects provided in this embodiment of the utility model has the following advantages:

[0019] This device operates on the same principle as conventional waste treatment equipment, utilizing the rapid reciprocating motion of the processing chamber to separate waste particles. Its unique feature lies in leveraging this reciprocating motion, coupled with a conventional gearbox and a ratchet mechanism on the main roller, to achieve slow rotation of the sorting disc within the chamber. This slow rotation not only allows for switching between through-hole areas on the disc but also, due to the disc's structural characteristics, enables multiple separation processes for waste particles. Even if through-hole blockage occurs, the rotating separation process ensures that new areas are available for separation. This rotating separation method reduces the frequency of disc cleaning and simplifies and simplifies the cleaning process. In summary, this waste treatment equipment, through the coordination of simple mechanical structures, achieves separation while also offering the advantages of low cleaning frequency and simplified cleaning.

[0024] This utility model provides a waste treatment device for building decoration and renovation projects, the specific implementation of which is as follows (in conjunction with the appendix). Figure 1 To be continued Figure 3 Please provide a detailed explanation. For example... Figure 1 As shown, the equipment mainly includes a base 1, a drive housing 2, a processing housing 3, a support plate 4, a slide rail frame 5, an eccentric wheel structure 6, a guide chute 7, and separation components, among other core components. Through a rational structural design and functional coordination, these components achieve efficient sorting, crushing, and screening of solid waste from building decoration and renovation projects.

[0025] The base 1 serves as the fundamental component of the entire equipment. A drive housing 2 is fixedly mounted on one side of its top, while a support plate 4 is installed on the other side. The drive housing 2 and the support plate 4 are fixedly connected by a slide rail frame 5, forming a stable frame structure. The slide rail frame 5 is a double-rail structure arranged at intervals, used to support and guide the reciprocating movement of the processing housing 3. The processing housing 3 is located between the slide rail frames 5, with open structures at both the top and bottom for easy material input and output. The output end of the drive housing 2 is connected to the processing housing 3 via an eccentric wheel structure 6. When the drive housing 2 is running, the eccentric wheel structure 6 drives the processing housing 3 to reciprocate horizontally along the slide rail frame 5. This reciprocating motion is the key power source for achieving waste particle separation. An inclined guide chute 7 is also fixedly installed on the base 1. The guide chute 7 is located at the bottom of the processing housing 3 and is used to guide the processed material to the subsequent collection device.

[0026] The processing chamber 3 contains a separation component, which is the core part of this equipment. Its structure is as follows: Figure 2 As shown. The separation assembly includes a sorting disc 8, arc-shaped baffles 10, inclined baffles 11, and other auxiliary components. The sorting disc 8 is rotatably mounted inside the processing chamber 3 via bearings. Its surface has multiple evenly distributed through holes 9, the size of which is designed according to actual needs to accommodate waste particles of different sizes. Two arc-shaped baffles 10 are spaced apart along the axial direction of the sorting disc 8 and fixedly connected to the inner walls of both sides of the processing chamber 3; two inclined baffles 11 are spaced apart along the radial direction of the sorting disc 8 and similarly fixed to the inner walls of both sides of the processing chamber 3. The heights of both the arc-shaped baffles 10 and the inclined baffles 11 are greater than the height of the axis of the sorting disc 8, and both fit into the surface of the sorting disc 8, together forming the sorting chamber. The sorting chamber is enclosed by the arc-shaped baffles 10, the inclined baffles 11, the top surface of the sorting disc 8, and the inner walls of the processing chamber 3, and its function is to classify, screen, and separate waste particles.

[0027] To achieve slow rotation of the sorting disc 8, main rollers 12 that cooperate with the slide rails 5 are installed on both sides of the processing box 3. Each main roller 12 is equipped with a ratchet mechanism 13 with unidirectional transmission. The main rollers 12 are connected to the sorting disc 8 via a gearbox 14. When the processing box 3 reciprocates on the slide rails 5, the main rollers 12 roll accordingly. However, due to the presence of the ratchet mechanism 13, only unidirectional rolling transmits power to the gearbox 14, thus driving the sorting disc 8 to rotate slowly. This design fully utilizes the reciprocating motion characteristics of the processing box 3, enabling the sorting disc 8 to switch between through-hole 9 areas while separating waste particles. When a through-hole 9 in a certain area becomes blocked, the rotation of the sorting disc 8 can switch to a new through-hole 9 area to continue the separation work, thereby significantly reducing the cleaning frequency and improving work efficiency.

[0028] Furthermore, such as Figure 1 As shown, a secondary housing 15 is fixedly connected to the side of the processing housing 3 away from the drive housing 2. Secondary rollers 16, which cooperate with the slide rail frame 5, are rotatably mounted on both sides of the secondary housing 15. The secondary housing 15, secondary rollers 16, main rollers 12, and sorting disc 8 are all in the same plane to ensure the stability of the overall structure. A rectangular groove 17 is provided at the junction of the processing housing 3 and the secondary housing 15. A vertically arranged guide rod 18 is fixedly connected inside the secondary housing 15, and a horizontally arranged push rod 19 is slidably connected to the guide rod 18. A scraper 20 is fixedly connected to one end of the push rod 19 facing the rectangular groove 17. The scraper 20 is equipped with flexible bristles for cleaning residues on the surface of the sorting disc 8. A connecting rod frame is connected to the other end of the push rod 19, and pins are fixedly connected to both ends of the connecting rod frame. Cams, which are driven by the secondary rollers 16, are provided on both sides inside the secondary housing 15. Arc-shaped grooves that cooperate with the pins are provided on the cams. When the processing box 3 reciprocates, the auxiliary roller 16 drives the cam to rotate. The arc groove on the cam interacts with the pin, causing the scraper 20 at one end of the push rod 19 to reciprocate on the surface of the sorting disk 8, thereby realizing the automatic cleaning function of the surface of the sorting disk 8.

[0029] To prevent dust from entering the secondary housing 15 and affecting equipment operation, an elastic sealing layer is fixedly connected to the push rod 19. This elastic sealing layer is sealed to the inner wall of the secondary housing 15 and is located between the guide rod 18 and the scraper 20. The elastic sealing layer isolates the internal space of the secondary housing 15 into a closed chamber, within which the connecting rod frame and cam are located. Furthermore, airflow channels are provided inside both the scraper 20 and the push rod 19. Multiple air jet holes are provided on the side of the scraper 20 with flexible bristles for blowing away fine particles from the surface of the sorting disc 8. An exhaust pipe connected to the airflow channels is fixedly connected to the connecting rod frame. An air inlet pipe is fixedly installed on the top of the secondary housing 15. Both the exhaust pipe and the air inlet pipe are equipped with one-way valves to ensure unidirectional airflow. A dust cover is fixedly connected to the top of the air inlet pipe to prevent external dust from entering the secondary housing 15.

[0030] To further enhance the intelligence of the equipment, a detection box is fixedly connected to the side of the processing chamber 3 opposite to the rectangular groove 17. An infrared sensor is installed inside the detection box to monitor the working status of the sorting disc 8 in real time. A transparent observation window is fixedly installed at the joint between the detection box and the processing chamber 3, allowing operators to observe the internal conditions. Electromagnetic clutches are fixedly connected to both sides of the auxiliary chamber 15 to control the transmission connection between the auxiliary roller 16 and the cam. When the sorting disc 8 needs cleaning, the electromagnetic clutches are activated, engaging the auxiliary roller 16 with the cam, thereby achieving the automatic cleaning function of the scraper 20. A discharge door is installed on one side of the sorting chamber in the processing chamber 3 for periodically cleaning residues within the sorting chamber.

[0031] In practical applications, the operation process of this equipment is as follows: First, solid waste generated during construction and decoration projects is poured into the top opening of the processing box 3. Under the action of gravity, the waste falls into the sorting bin. After the drive box 2 is started, the eccentric wheel structure 6 drives the processing box 3 to move back and forth on the slide rail frame 5. At the same time, the main roller 12 drives the sorting disc 8 to rotate slowly through the pawl mechanism 13 and the gearbox 14. The through holes 9 on the sorting disc 8 perform preliminary screening of the waste. Smaller particles fall into the guide trough 7 through the through holes 9, while larger particles remain on the surface of the sorting disc 8 for further separation. The function of the arc-shaped baffle 10 and the inclined baffle 11 is to guide the waste to tumble continuously in the sorting bin, thereby achieving a more refined separation effect. When blockage or residue appears on the surface of the sorting disc 8, the scraper 20 automatically cleans itself through the cooperation of the cam and the pin. The flexible bristles and the air jet work together to ensure that the surface of the sorting disc 8 is always kept clean. Infrared sensors monitor the working status of sorting disc 8 in real time. When an abnormality is detected, the control system can adjust the equipment operating parameters or initiate a cleaning program. Finally, the processed material is discharged through the feed chute 7, and the residue in the sorting chamber is periodically cleaned through the discharge gate.

[0032] In summary, this utility model, through ingenious mechanical structure design and functional integration, not only achieves efficient separation of construction and decoration project waste, but also significantly reduces the difficulty of equipment cleaning and maintenance, and improves overall operating efficiency.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
