[0001] The utility model relates to the technical field of primary screening and sorting of garbage, in particular to a primary screening and sorting platform before incineration of domestic garbage. Background Art

[0002] Incineration of domestic waste is a common waste treatment method, which converts waste into heat energy, electricity and usable ash and other byproducts through high-temperature incineration. Domestic waste is of various types and complex composition, including combustibles, non-combustibles, metals, glass, plastics, paper, organic matter, etc. Through preliminary screening and sorting before incineration, usable resources (such as metals, plastics, paper, etc.) can be recovered to reduce waste. At the same time, by removing harmful substances, the amount of harmful substances generated during the incineration process can be reduced.

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] Reference Figure 1-Figure 3 The utility model provides an embodiment: a pre-screening and sorting platform for incineration of domestic waste, comprising: a base 1 for providing support and installation for the sorting platform, the base 1 is made of steel and fixed to the ground with a bolt structure to ensure the stability of the pre-screening and sorting platform during operation. A bracket 2 is fixedly connected to the left side of the top of the base 1, a mounting frame 3 is rotatably connected to the top of the bracket 2, and a water screen plate 4 is fixedly connected to the bottom of the mounting frame 3. When domestic waste is transported to the water screen plate 4, liquid waste is guided out through the holes distributed on the water screen plate 4 to separate it from solid waste. At the same time, the rotating connection between the mounting frame 3 and the bracket 2 can ensure that the water screen plate 4 is in a movable state, so that the water screen plate 4 can achieve vibration and rapid separation of solid and liquid waste. A water collection bin 17 for collecting liquid waste is fixedly installed at the bottom of the water screen plate 4, and a sewage outlet 18 is installed on the outer wall of the water collection bin 17. The liquid waste passing through the water screen plate 4 will enter the water collection bin 17 for collection. At the same time, the valve on the sewage outlet 18 can be opened to discharge the collected liquid waste and then transport it to the sewage treatment equipment for treatment. A plurality of flow-limiting inclined blocks 5 for limiting the flow rate of the liquid are fixedly connected to the top of the water screen plate 4. The plurality of flow-limiting inclined blocks 5 arranged at an angle on the top can serve the purpose of continuing the liquid waste and ensure that the liquid waste on the water screen plate 4 has enough time to penetrate through the water screen plate 4 and enter the water collection bin 17.

[0037] Reference Figure 1-Figure 2, a vibration component is used to vibrate the water screen plate 4 to quickly separate solid garbage and liquid garbage. It is installed on the top right side of the base 1. The vibration component includes a support frame 6, which is fixedly connected to the top right side of the base 1. A rotating rod 7 is rotatably connected to the inner side of the support frame 6. Cams 8 are fixedly connected to both sides of the outer periphery of the rotating rod 7. A first driven wheel 9 is fixedly connected to the front end of the rotating rod 7. The driving component will drive the first driven wheel 9 to rotate, and then drive the rotating rod 7 to rotate through the first driven wheel 9, so that the rotating rod 7 can drive the two cams 8 outside it to rotate, and the bottom of the mounting frame 3 is continuously lifted upward by the rotation of the cam 8, thereby achieving the vibration effect on the water screen plate 4; the outer wall of the cam 8 is abutted against the bottom of the mounting frame 3, so that the cam 8 can push the mounting frame 3 at the first time when it rotates, causing it to flip upward.

[0038] Reference Figure 2 and Figure 4, a separation box 20 is installed on the left side of the base 1. A separation component for separating magnetically absorbable metal waste and other solid waste is arranged inside the separation box 20. A conveyor belt 21 for conveying the initially screened waste is fixedly installed on the left side of the separation box 20. The waste after the initial screening and sorting will fall on the conveyor belt 21 for continued transportation. During the process, the domestic waste after the initial screening is sorted again by cooperating with the corresponding sorting equipment installed on both sides of the conveyor belt 21 or manual sorting; the separation component includes a magnetic roller 22, which is rotatably connected to the middle side of the separation box 20. The front end of the magnetic roller 22 passes through the separation box 20 and is fixedly connected to a second driven wheel 23. The driving component drives the second driven wheel 23 to rotate, and then drives the magnetic roller 22 to rotate, so that the magnetically absorbable metal waste in the dehydrated domestic waste will be adsorbed and sorted out during the rotation of the magnetic roller 22, thereby achieving a rapid sorting effect. A scraper 25 is provided on the right side of the outer periphery of the magnetic roller 22 to abut against it. A plurality of spring rods 24 are fixedly connected to the side of the scraper 25 away from the magnetic roller 22, and the other end of the spring rod 24 is fixedly connected to the inner wall of the separation box 20. An elastic structure is installed inside the spring rod 24 to enable it to push the scraper 25 and the magnetic roller 22 to be in close contact, ensuring that the scraper 25 can scrape off the magnetically adsorbable metal waste adsorbed on the magnetic roller 22, thereby realizing the rapid sorting and collection of the magnetically adsorbable metal waste. A partition 26 for separating the magnetically adsorbable metal waste is provided below the magnetic roller 22. The partition 26 isolates the sorted magnetically adsorbable metal waste inside the separation box 20, while other solid waste falls on the conveyor belt 21 and continues to be transported to the next process for secondary sorting. The left side of the water screen plate 4 is fixedly connected with an elastic discharge port 19, and the bottom of the elastic discharge port 19 is in contact with the top of the magnetic roller 22. The elastic discharge port 19 made of elastic material can ensure that the garbage falling from the water screen plate 4 will fall accurately on the magnetic roller 22, thereby ensuring that the magnetically adsorbable metal garbage in the solid garbage can directly contact the magnetic roller 22, thereby achieving the separation of the magnetically adsorbable metal garbage. The right side of the conveyor belt 21 extends into the separation box 20, and the right side of the conveyor belt 21 is located on the left side of the partition 26. The non-metallic solid garbage that slides off the left side of the magnetic roller 22 will directly fall onto the conveyor belt 21, and then continue to be transported to the next sorting process.

[0039] Reference Figure 1 The driving assembly is used to drive the vibration assembly and the separation assembly in linkage. The driving assembly includes a motor 10, which is fixedly mounted in the middle of the base 1. The output end of the motor 10 is fixedly connected to a double-layer driving wheel 11, which is respectively connected to the first driven wheel 9 and the second driven wheel 23 through a belt. The motor 10 starts to drive the double-layer driving wheel 11 to rotate, so that the double-layer driving wheel 11 synchronously drives the first driven wheel 9 and the second driven wheel 23 to rotate under the cooperation of the belt, and then drives the vibration assembly and the separation assembly to run simultaneously.

[0040] Reference Figure 2 and Figure 5 A plurality of supports 12 are fixedly connected to the right side of the top of the base 1, and a guide rod 13 is hinged on the top of the support 12. A limit ring 14 is fixedly connected to the bottom of the outer periphery of the guide rod 13, and a spring 15 is sleeved on the middle part of the outer periphery of the guide rod 13. A sleeve 16 is slidably connected to the top of the outer periphery of the guide rod 13, and the top of the sleeve 16 is hinged to the bottom of the water screen plate 4. When the rotating rod 7 rotates, the cam 8 will be synchronously driven to rotate, and the bottom of the mounting frame 3 will be continuously lifted upward. During the process, the sleeve 16 will be pulled by the water screen plate 4 to slide upward along the outer wall of the guide rod 13, and the spring 15 will be stretched at the same time. When the cam 8 rotates so that its bottom contacts the bottom of the mounting frame 3, the mounting frame 3 and the water screen plate 4 will be quickly pulled downward and flipped under the action of the sleeve 16, so that the water screen plate 4 can vibrate quickly in this reciprocating manner, thereby improving the efficiency of solid-liquid separation. One end of the spring 15 is fixedly connected to the top of the limit ring 14, and the other end of the spring 15 is fixedly connected to the bottom of the sleeve 16. The spring 15 pulls the sleeve 16 so that the water screen plate 4 can obtain a faster frequency when vibrating, thereby improving the speed and quality of solid-liquid separation.

[0041] Working principle: domestic garbage is transported to the water screening plate 4 of the platform through the conveying equipment. At this time, the starting motor 10 drives the rotating rod 7 to rotate through the cooperation of the double-layer driving wheel 11 and the first driven wheel 9. The rotation of the rotating rod 7 will drive the cam 8 to rotate and continuously push the bottom of the mounting frame 3 upward. During the process, the sleeve 16 will slide upward along the outer wall of the guide rod 13 and stretch the spring 15. When the cam 8 rotates to make its bottom contact with the bottom of the mounting frame 3, the mounting frame 3 will be quickly pulled down and flipped under the action of the sleeve 16. This reciprocating movement allows the mounting frame 3 to drive the water screening plate 4 to vibrate rapidly, and then the domestic garbage falling on the water screening plate 4 will vibrate rapidly, so that liquid garbage and solid garbage are quickly separated. After that, the liquid garbage that is shaken off will pass through the water screening plate 4 and fall into the water collecting bin 17 to be collected. During the process, the flow limiting inclined block 5 is used to slow down the flow speed of the liquid garbage on the water screening plate 4 to ensure that the liquid garbage can flow into the water collecting bin 17 as much as possible.

[0042] At the same time, with the operation of the driving component, the double-layer active wheel 11 will also drive the magnetic roller 22 to rotate through the cooperation with the second driven wheel 23. At this time, the solid garbage on the water screen plate 4 will fall from the elastic discharge port 19 along the inclined water screen plate 4 under the action of vibration. In the process, the solid garbage will directly fall on the top of the magnetic roller 22 along the elastic discharge port 19 and fall toward the left side of the magnetic roller 22. At this time, the magnetically adsorbable metal garbage in the solid garbage will be attracted by the magnetic roller 22. With the rotation of the magnetic roller 22, the adsorbed magnetically adsorbable metal garbage will be sorted out from the solid garbage. The solid domestic garbage after separating the magnetically adsorbable metal garbage will fall from the left side of the magnetic roller 22 onto the conveyor belt 21, and then continue to be transported by the conveyor belt 21. At the same time, the workers can further complete the further sorting of other garbage on both sides of the conveyor belt 21.

[0043] The magnetically absorbable metal waste separated by the magnetic roller 22 will move from the top of the partition 26 to the bottom of the scraper 25 as the magnetic roller 22 rotates. During the process, the magnetically absorbable metal waste will be scraped off the surface of the magnetic roller 22 by the scraper 25 and fall into the collection space between the separation box 20 and the magnetic roller 22, thereby completing the rapid sorting of the magnetically absorbable metal waste.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
