Description
Technical Field
[0001] This utility model relates to the field of solid waste treatment technology, specifically to a special environmental protection device for the comprehensive utilization of solid waste. Background Technology
[0002] Against the backdrop of environmental protection and resource utilization, the effective treatment of solid waste is becoming increasingly crucial. With rapid industrialization and urbanization, the amount of solid waste generated has increased dramatically.
[0003] However, most current solid waste treatment equipment has many drawbacks. In terms of dust and impurity separation, traditional equipment often lacks effective air separation and dust collection mechanisms, making it difficult to completely separate dust and light impurities in solid waste. These residual impurities not only affect the effectiveness of subsequent processing, but also accumulate inside the equipment, accelerating wear and tear, shortening the equipment's service life, and resulting in unsatisfactory crushing efficiency and quality. Utility Model Content
[0004] The purpose of this utility model is to provide a special environmental protection equipment for the comprehensive utilization of solid waste, which solves the technical problems of existing solid waste treatment equipment, such as incomplete separation of dust and impurities, low crushing efficiency, uneven particle size of processed materials, and easy wear of equipment. It achieves the purpose of efficient separation of dust and impurities, improved crushing efficiency and quality, and control of output particle size.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a special environmental protection equipment for comprehensive utilization of solid waste, comprising a crushing barrel, an air separation and ash removal section, and a mixing and crushing processing section, wherein a feeding hopper is connected to one side of the outer wall of the crushing barrel; the air separation and ash removal section is connected to the outer wall of the crushing barrel; and the mixing and crushing processing section is located inside the crushing barrel.
[0006] Preferably, the air separation dust removal section specifically includes: a ventilation box, which is connected to the outer wall of the crushing barrel; an air separation screen mounting groove, which is symmetrically opened on the inner wall of the crushing barrel; and a dust extraction box, which is connected to the outer wall of the crushing barrel.
[0007] Preferably, air classifier screen plate one and air classifier screen plate two are slidably installed inside the air classifier screen installation groove, and the outer wall of the ventilation box is provided with installation openings at equal intervals.
[0008] Preferably, a ventilation screen block is fixedly installed on the inner wall of the installation port, a wind separator is provided on the outer wall of the ventilation screen block, a dust collection hopper is connected to one side of the outer wall of the dust collection box, a dust collection pipe interface is connected to the outer wall of the dust collection hopper, a dust collection pipe is connected to the dust collection pipe interface, and a vacuum cleaner is connected to the other end of the dust collection pipe.
[0009] An air classifier fan is installed on the outer wall of the ventilation screen block, working in conjunction with the ventilation box, air classifier screen plate one, and air classifier screen plate two. When the air classifier fan starts, it generates a strong airflow that passes through the ventilation screen block and enters the crushing chamber. While solid waste is being processed by the agitation and crushing unit inside the crushing chamber, lighter impurities and dust are blown towards air classifier screen plates one and two by the airflow. The air classifier screen plates can block larger solid waste particles, allowing lighter impurities and dust to pass through smoothly, achieving efficient separation from the solid waste and improving the purity of subsequent processing.
[0010] Preferably, the mixing and pulverizing processing unit specifically includes: a motor mounting bracket, fixedly installed on the top outer wall of the pulverizing barrel; a pulverizing motor, disposed on the top outer wall of the pulverizing barrel; a discharge hopper, connected to the bottom outer wall of the pulverizing barrel; a discharge valve pipe, connected to the bottom outer wall of the discharge hopper; a first pulverizing screen, disposed on the inner wall of the pulverizing barrel; and a second pulverizing screen, disposed on the inner wall of the pulverizing barrel.
[0011] Preferably, the crushing motor is fixedly installed on the inner wall of the motor mounting bracket, and both the first crushing screen and the second crushing screen are fixedly installed on the inner wall of the crushing barrel.
[0012] The system is equipped with two crushing screens, which can divide the crushing process into multiple stages, allowing solid waste to be gradually refined in different areas. Large particles are first crushed above the screens, and after reaching a certain particle size, they pass through the screens to enter the next area for finer crushing. This avoids the problem of insufficient crushing caused by processing a large amount of materials of different particle sizes at once, and improves the overall crushing efficiency.
[0013] Preferably, the output end of the crushing motor is fixedly connected to a stirring rod, and the other end of the stirring rod movably penetrates the top outer wall of the crushing barrel, the first crushing screen, and the second crushing screen, and extends to the bottom outer wall of the second crushing screen.
[0014] Preferably, a rotating sleeve is fixedly sleeved on the outer wall of the stirring rod, and a first pulverizing blade and a second pulverizing blade are fixedly installed on the outer wall of the rotating sleeve at equal intervals around the circumference. The first pulverizing blade is set on the top outer wall of the first pulverizing screen.
[0015] Preferably, the second pulverizing blade is disposed on the bottom outer wall of the second pulverizing screen, and the outer wall of the stirring rod is circumferentially fixedly connected with a stirring pulverizing rod, and one side of the outer wall of the stirring pulverizing rod is fixedly installed with pulverizing teeth, and the stirring pulverizing rod is disposed between the first pulverizing screen and the second pulverizing screen.
[0016] A stirring and pulverizing rod is installed, which works in conjunction with pulverizing blades at different positions to form a multi-stage pulverizing system. The stirring and pulverizing rod operates in the middle area, working in cooperation with the upper and lower pulverizing blades to pulverize solid waste multiple times and from multiple angles. Large particles are first initially crushed by the upper blades, then further refined by the stirring and pulverizing rod in the middle area, and finally finely pulverized by the lower blades, ensuring that solid waste is fully crushed and improving pulverizing efficiency and quality.
[0017] This utility model provides a special environmental protection device for the comprehensive utilization of solid waste. It has the following beneficial effects:
[0018] (1) This utility model can effectively separate dust and light impurities from solid waste through the action of air separation screen plate and wind. When solid waste enters the crushing barrel, the wind generated by the air separation fan makes dust and light impurities fly. When passing through the air separation screen plate, dust and impurities are intercepted and collected by the vacuum cleaner through components such as dust collection bucket and dust collection pipe. This helps to improve the purity of solid waste in subsequent processing stages, reduce the interference of impurities on equipment and processing technology, and ensure the effect and quality of comprehensive utilization.
[0019] (2) This utility model sets up crushing blades and stirring crushing rods at different positions in the stirring and crushing processing section to form a multi-stage crushing system. The upper crushing blades initially crush the solid waste entering the crushing barrel and decompose larger lumps. The middle stirring crushing rods work with the crushing teeth to further refine the material. The lower crushing blades perform fine crushing to ensure that the solid waste can be fully crushed into smaller particles, thereby improving crushing efficiency and quality. The continuous stirring action can prevent solid waste from accumulating near the screen and avoid affecting the normal operation of the equipment due to material clogging the screen.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0026] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0027] Example 1:
[0028] Based on the existing problems of incomplete separation of dust and impurities, low crushing efficiency, uneven particle size of processed materials, and easy wear of equipment, this utility model provides a preferred embodiment of a special environmental protection equipment for comprehensive utilization of solid waste, for example... Figures 1-4 As shown: A special environmental protection equipment for comprehensive utilization of solid waste includes a crushing barrel 1, an air separation and ash removal section 3, and a mixing and crushing processing section 4. A feeding hopper 2 is connected to one side of the outer wall of the crushing barrel 1; the air separation and ash removal section 3 is connected to the outer wall of the crushing barrel 1; and the mixing and crushing processing section 4 is located inside the crushing barrel 1.
[0029] The air separation and dust removal section 3 specifically includes: a ventilation box 312, which is connected to the outer wall of the crushing barrel 1; an air separation screen mounting groove 311, which is symmetrically opened on the inner wall of the crushing barrel 1; and a dust extraction box 315, which is connected to the outer wall of the crushing barrel 1.
[0030] The air classifier screen installation chute 311 has an air classifier screen plate 318 and an air classifier screen plate 319 slidably installed inside, and the outer wall of the ventilation box 312 has installation openings at equal intervals.
[0031] A ventilation screen block 313 is fixedly installed on the inner wall of the installation port. A wind separator fan 314 is installed on the outer wall of the ventilation screen block 313. A dust collection hopper 316 is connected to one side of the outer wall of the dust collection box 315. A dust collection pipe interface 317 is connected to the outer wall of the dust collection hopper 316. A dust collection pipe 3111 is connected to the dust collection pipe interface 317. A vacuum cleaner 3112 is connected to the other end of the dust collection pipe 3111.
[0032] In this embodiment, the air classifier fan 314 is turned on. The air classifier fan 314 is installed on the ventilation screen block 313 on the outer wall of the ventilation box 312. The ventilation screen block 313 plays a preliminary filtering role, preventing large particles of impurities from entering the ventilation box 312. The air force generated by the air classifier fan 314 enters the crushing barrel 1 through the ventilation box 312, causing the dust and light impurities in the solid waste in the crushing barrel 1 to fly up. The flying dust and light impurities move towards the dust extraction box 315 under the action of the air force, and pass through the air classifier screen plate 318 and the air classifier screen. Plate 2 319, air separation screen plate 1 318, and air separation screen plate 2 319 are installed in the air separation screen installation groove 311 to screen dust and impurities, allowing only dust and impurities that meet certain particle sizes to pass through. When the vacuum cleaner 3112 is activated, the dust and impurities are sucked into the vacuum cleaner 3112 through the vacuum bucket 316, the vacuum pipe interface 317, and the vacuum pipe 3111, realizing the collection and removal of dust and impurities. This helps to improve the purity of solid waste in subsequent treatment stages, reduce the interference of impurities on equipment and processing technology, and ensure the effect and quality of comprehensive utilization.
[0033] Example 2:
[0034] Please see Figures 1-4 Furthermore, based on Embodiment 1, the mixing and pulverizing processing unit 4 specifically includes: a motor mounting bracket 411, fixedly installed on the top outer wall of the pulverizing barrel 1; a pulverizing motor 412, disposed on the top outer wall of the pulverizing barrel 1; a discharge hopper 418, connected to the bottom outer wall of the pulverizing barrel 1; a discharge valve pipe 419, connected to the bottom outer wall of the discharge hopper 418; a first pulverizing screen 414, disposed on the inner wall of the pulverizing barrel 1; and a second pulverizing screen 417, disposed on the inner wall of the pulverizing barrel 1.
[0035] The crushing motor 412 is fixedly installed on the inner wall of the motor mounting bracket 411, and the crushing screen 1 414 and the crushing screen 2 417 are both fixedly installed on the inner wall of the crushing barrel 1.
[0036] The output end of the crushing motor 412 is fixedly connected to a stirring rod. The other end of the stirring rod moves through the top outer wall of the crushing barrel 1, the first crushing screen 414 and the second crushing screen 417, and extends to the bottom outer wall of the second crushing screen 417.
[0037] A rotating sleeve is fixedly fitted on the outer wall of the stirring rod. Crushing blade 1 413 and crushing blade 2 416 are fixedly installed on the outer wall of the rotating sleeve at equal intervals around the circumference. Crushing blade 1 413 is set on the top outer wall of crushing screen 1 414.
[0038] The second pulverizing blade 416 is set on the bottom outer wall of the second pulverizing screen 417. The outer wall of the stirring rod is fixedly connected with the stirring pulverizing rod 415 at equal intervals. The outer wall of the stirring pulverizing rod 415 is fixedly installed with pulverizing teeth at equal intervals on one side. The stirring pulverizing rod 415 is set between the first pulverizing screen 414 and the second pulverizing screen 417.
[0039] In this embodiment, the crushing motor 412 is started. The crushing motor 412 is fixedly installed on the inner wall of the motor mounting bracket 411. The output end of the crushing motor 412 drives the stirring rod to rotate, and the rotating sleeve on the stirring rod rotates accordingly. The crushing blade 413 on the outer wall of the rotating sleeve is set on the top outer wall of the crushing screen 414, which initially crushes the larger solid waste that has just entered the crushing barrel 1. The stirring rod continues to rotate, and the stirring and crushing rod 415 located between the crushing screen 414 and the crushing screen 417 starts to work. The crushing teeth on one side of the outer wall of the stirring and crushing rod 415 undergo initial crushing. The pulverized solid waste is further refined, and the stirring action of the stirring and pulverizing rod 415 makes the material distribution more uniform, promoting full contact between the material and each pulverizing component. The material after being processed by the stirring and pulverizing rod 415 reaches below the second pulverizing screen 417. At this time, the pulverizing blades 416 driven by the stirring rod finely pulverize the material to ensure that the material meets the required particle size requirements, ensuring that the solid waste can be fully broken into smaller particles, improving pulverization efficiency and quality. The continuous stirring action can prevent solid waste from accumulating near the screen and avoid affecting the normal operation of the equipment due to material clogging the screen.
[0040] Working principle: When in use;
[0041] Step 1: The solid waste to be processed is fed into the crushing barrel 1 through the feed hopper 2. The feed hopper 2 serves as the material inlet to ensure that the solid waste can smoothly enter the subsequent processing stage.
[0042] Step Two: Turn on the air classifier fan 314. The air classifier fan 314 is installed on the ventilation screen block 313 on the outer wall of the ventilation box 312. The ventilation screen block 313 plays a preliminary filtering role, preventing large particles of impurities from entering the ventilation box 312. The air force generated by the air classifier fan 314 enters the crushing barrel 1 through the ventilation box 312, causing the dust and light impurities in the solid waste in the crushing barrel 1 to fly up. The flying dust and light impurities are driven towards the dust extraction box 31 by the air force. The device moves in five directions, passing through the first air separation screen plate 318 and the second air separation screen plate 319. The first air separation screen plate 318 and the second air separation screen plate 319 are installed in the air separation screen installation groove 311 to screen dust and impurities, allowing only dust and impurities that meet a certain particle size to pass through. The vacuum cleaner 3112 is activated, and the dust and impurities are sucked into the vacuum cleaner 3112 through the dust collection hopper 316, the dust collection pipe interface 317 and the dust collection pipe 3111, realizing the collection and removal of dust and impurities.
[0043] Step 3: Start the crushing motor 412. The crushing motor 412 is fixedly installed on the inner wall of the motor mounting bracket 411. The output end of the crushing motor 412 drives the stirring rod to rotate, and the rotating sleeve on the stirring rod rotates accordingly. The crushing blade 413 on the outer wall of the rotating sleeve is set on the top outer wall of the crushing screen 414 to initially crush the larger solid waste that just enters the crushing barrel 1. The stirring rod continues to rotate, and the stirring crushing rod 415 located between the crushing screen 414 and the crushing screen 417 starts to work. The crushing teeth on one side of the outer wall of the stirring crushing rod 415 further refine the solid waste that has been initially crushed. At the same time, the stirring action of the stirring crushing rod 415 makes the material distribution more uniform and promotes full contact between the material and each crushing component. The material after being processed by the stirring crushing rod 415 reaches the bottom of the crushing screen 417. At this time, the crushing blade 416 driven by the stirring rod finely crushes the material to ensure that the material meets the required particle size requirements.
[0044] Step 4: Crushing screen 1 414 and crushing screen 2 417 screen the crushed material. Only the material with the required particle size can pass through the screen. Large particles that do not pass through the screen remain above the screen and are crushed by the corresponding crushing components. The material that has been screened and has the required particle size passes through the discharge hopper 418 and is finally discharged from the discharge valve pipe 419, completing the entire solid waste treatment process.
[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
