Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment technology, specifically to an asphalt concrete solid waste treatment device. Background Technology

[0002] Asphalt concrete solid waste treatment equipment is a system specifically designed for processing asphalt concrete waste generated after the demolition of urban roads and highways. After processing such as crushing and screening, this waste can be reused as aggregate in building and transportation construction, achieving resource recycling, reducing construction costs, and minimizing environmental impact.

[0003] The patent with publication number CN222535061U discloses an asphalt concrete solid waste treatment device, including a box body with a solid waste inlet pipe. The box body has outlets on both sides and placement openings on both sides. Two crushing rollers are rotatably mounted on the box body via bearings and are meshed together. A support plate is installed inside the box body. Solid waste such as asphalt concrete enters the box body through the solid waste inlet pipe, and the crushing rollers rotate inward to crush the incoming solid waste. The crushed solid waste is discharged through the inclined surface of a magnetic plate and exits the box body through the outlet. Metal materials mixed in with the solid waste are adsorbed onto the surface of the magnetic plate. When crushing stops, the output end of a hydraulic cylinder drives a pusher plate to advance from one placement opening, quickly scraping off the metal materials on the surface of the magnetic plate and pushing them into a collection box through the other placement opening, where they are compressed into blocks for easy collection.

[0004] However, the above technology still has the following problems:

[0005] During the crushing and screening of asphalt concrete solid waste, a significant amount of dust is generated. Workers who are exposed to dusty air for extended periods are prone to inhaling dust particles, which can lead to respiratory illnesses such as coughing, asthma, bronchitis, and pneumoconiosis. Dust entering the eyes can cause discomfort such as stinging, tearing, and redness, and long-term irritation may lead to eye diseases. Dust adhering to the skin can clog pores, causing skin problems such as itching and inflammation. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 4 An asphalt concrete solid waste treatment device includes a treatment box 1. A hopper 2 is fixedly connected to the upper end of the treatment box 1. A crushing roller 3 is installed inside the hopper 2. A screen 4 is installed inside the treatment box 1. A vibrating motor 5 is installed on the screen 4. A dust collector 6 is fixedly connected to the upper surface of the treatment box 1. An air inlet pipe 1 7 and an air inlet pipe 2 8 are connected to the upper part of the dust collector 6. The air inlet pipe 1 7 is connected to the inside of the treatment box 1. The air inlet pipe 2 8 is located on one side of the hopper 2. A support plate 9 is fixedly connected to the inner wall of the dust collector 6. A circular hole 10 is opened on the support plate 9. An external threaded pipe 11 is fixedly connected to the lower surface of the support plate 9. A filter mechanism is threadedly connected to the external threaded pipe 11. A negative pressure mechanism is installed on the surface of the dust collector 6. A sealing mechanism is installed on the side of the dust collector 6. Several limiting plates 12 are fixedly connected to the sealing mechanism. A fixing component matching the limiting plates 12 is fixedly connected to the side of the dust collector 6.

[0023] The asphalt concrete solid waste treatment equipment in this utility model is structurally similar to existing asphalt concrete solid waste treatment equipment. For example, patent CN222535061U discloses an asphalt concrete solid waste treatment equipment. The main improvement of this utility model is that it can simultaneously perform crushing and screening, and absorb the dust generated during operation to reduce harm to workers. Figures 1 to 4As shown, in the asphalt concrete solid waste treatment equipment of this utility model, solid waste is placed into the hopper 2 and crushed by the crushing roller 3. The crushed solid waste enters the interior of the treatment box 1 and is screened by the screen 4. During the crushing and screening process, as well as during the process of pouring solid waste into the hopper 2, the negative pressure mechanism generates negative pressure to draw air into the dust collection box 6, thereby drawing air into the interior of the dust collection box 6 from the air inlet pipe 7 and the air inlet pipe 8. The filter mechanism inside the dust collection box 6 filters the dust in the air, thereby reducing the dust in the working area and reducing the harm to the workers. At the same time, it is also convenient to release the fixing component from the limiting plate 12, so that the sealing mechanism can be rotated to quickly remove the filter mechanism for replacement and cleaning.

[0024] like Figure 4 As shown, the filtration mechanism includes an internally threaded tube 13 that is threaded onto an externally threaded tube 11, and a cloth bag 14 is fixedly connected to the lower end of the internally threaded tube 13.

[0025] Specifically, the filter bag 14 can be installed and fixed by connecting the internally threaded tube 13 and the externally threaded tube 11 with threads, thereby filtering dust in the air during airflow.

[0026] like Figure 4 As shown, a plurality of limiting rods 15 arranged in a circular array are fixedly connected to the lower surface of the support plate 9.

[0027] Specifically, the limiting rod 15 can restrict the cloth bag 14, making it less likely to deform and stack together.

[0028] like Figure 1 As shown, the negative pressure mechanism includes an air pump 16 fixedly connected to the dust collection box 6. The air pump 16 is equipped with an air suction pipe 17 and an exhaust pipe 18. The air suction pipe 17 is connected to the interior of the dust collection box 6, and the middle section of the air suction pipe 17 is a flexible hose.

[0029] Specifically, the suction pump 16 starts and generates a strong suction force on the suction pipe 17, thereby creating a negative pressure inside the dust collection box 6. This causes the dust floating inside the processing box 1 to enter the air inlet pipe 7, while the dust at the top of the hopper 2 is sucked into the air inlet pipe 8 and enters the interior of the dust collection box 6, where it is filtered by the filtration mechanism.

[0030] like Figure 1 As shown, the sealing mechanism includes a sealing door 19 rotatably connected to the dust collection box 6, and a sealing gasket 20 is fixedly connected to the inner wall of the sealing door 19.

[0031] Specifically, opening the sealing door 19 facilitates the installation and disassembly of the filter mechanism. After the sealing door 19 is closed, it can be sealed by the sealing gasket 20, which will not affect the negative pressure inside the dust collection box 6.

[0032] like Figure 3 As shown, the fixing assembly includes two rotating blocks 21 fixedly connected to the dust collection box 6, a rotating shaft 22 rotatably connected between the two rotating blocks 21, a threaded rod 23 fixedly connected to the rotating shaft 22, an internally threaded tube 24 threadedly connected to the threaded rod 23, and an extrusion plate 25 fixedly connected to the upper end of the internally threaded tube 24.

[0033] Specifically, after the sealing door 19 is closed, the pressing plate 25 is moved to one side of the limiting plate 12, and then the pressing plate 25 is rotated, thereby driving the internal thread tube 24 to spiral on the threaded rod 23, and causing the pressing plate 25 to move and abut against the limiting plate 12, thereby fixing the sealing door 19.

[0034] like Figure 3 As shown, an anti-slip and wear-resistant pad 26 is fixedly connected to the surface of the extrusion plate 25.

[0035] Specifically, the anti-slip and wear-resistant pad 26 can increase the friction between the extrusion plate 25 and the sealing door 19, thereby enhancing the fixing effect.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
