Description

Technical Field

[0001] This invention relates to the field of solid waste sorting technology, specifically to a bulk solid waste sorting device for resource recovery. Background Technology

[0002] Currently, the amount of bulk solid waste generated annually is enormous, including construction waste, industrial slag, and household garbage. This solid waste not only occupies a large amount of land, but many of it also contains recyclable resources. Sorting and processing can reduce environmental pollution and damage, and improve land resource utilization efficiency. However, existing solid waste sorting devices generate large amounts of dust during operation, which disperses into the air, causing atmospheric pollution. Furthermore, magnetic substances in the solid waste cannot be separated from ordinary solid waste, resulting in the presence of valuable magnetic substances in the sorted solid waste. Summary of the Invention

[0004] The technical solution provided by this invention is as follows: A bulk solid waste sorting device for resource recycling includes a sorting section and a collection section located below the sorting section. Hydraulic cylinders for lifting the sorting section are symmetrically arranged on both sides of the sorting section and the collection section. The sorting section includes an outer dust cover. The ends of the telescopic rods of the two hydraulic cylinders are fixed to the outer dust cover. The interior of the outer dust cover is equipped with a sloping sliding surface and an inner sorting cover. The sloping sliding surface is located on the upper surface of the inner sorting cover. A sorting turntable is rotatably connected to the middle of the inner sorting cover via a sorting turntable bracket. A central drive shaft is fixedly installed in the middle of the sorting turntable.

A dust removal turntable connected to the central drive shaft is arranged inside the limiting shell.

[0005] Furthermore, an intermediate gear and a drive gear are rotatably mounted on the drive gear ring support plate. The drive gear and the drive gear ring are driven by meshing through the intermediate gear. A separate motor is fixedly mounted on the dust collection ring cover. The output shaft of the separate motor is connected to the drive gear and is used to drive the drive gear to rotate.

[0006] Furthermore, the dust collection ring is also equipped with an exhaust port, and a dust collection hose is installed at the exhaust port, with the other end of the dust collection hose connected to the vacuum cleaner.

[0007] Furthermore, the sorting turntable has multiple through holes along the radial direction, and the width of the through holes increases sequentially from the center of the sorting turntable outwards.

[0008] Furthermore, the collection unit includes a collection trough mounting base, which is fixedly mounted on a support frame, and the collection trough mounting base is provided with multiple layers of annular collection troughs.

[0009] Furthermore, a drive motor is fixedly installed on the support frame, and a hexagonal sleeve is fixedly installed on the output shaft of the drive motor. The hexagonal sleeve and the bottom end of the central drive shaft are axially slidingly engaged by a spline.

[0010] Furthermore, the top surface of the inner wall of the outer dust cover is fixed to the slope sliding surface by a connecting hanger, and the inner sorting cover is fixedly fitted to the slope sliding surface.

[0011] Furthermore, the upper surface of the sorting turntable is equipped with multiple actuating strips to drive the solid material on the surface to rotate. A sealing strip is provided between two adjacent electromagnets. The sealing strip is in contact with the electromagnet and is fixed on the electromagnet support.

[0012] Furthermore, the top end of the central drive shaft is slidably engaged with the dust removal turntable along the axial direction using a spline method, and a tension spring is arranged around the central drive shaft, with both ends of the tension spring fixed to the dust removal turntable and the central drive shaft respectively.

[0013] Furthermore, at least three bouncing wheel brackets are fixedly installed on the inner side of the limiting shell, and each bouncing wheel bracket is rotatably equipped with a bouncing wheel. Multiple bouncing protrusions that roll in cooperation with the bouncing wheels are fixedly installed on the lower surface of the dust removal turntable, and multiple raised stripes are arranged radially on the upper surface of the dust removal turntable.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention can separate dust from solid waste by combining the dust removal turntable and the dust suction ring, and also separate the dust that is easily detached from the solid waste.

[0031] like Figure 1-12The illustrated bulk solid waste sorting device for resource recycling includes a sorting section 2 and a collection section 1 located below the sorting section 2. Hydraulic cylinders 4 for lifting the sorting section 2 are symmetrically arranged on both sides of the sorting section 2 and the collection section 1. The sorting section 2 includes an outer dust cover 204. The ends of the extension rods of the two hydraulic cylinders 4 are fixed to the outer dust cover 204. The outer dust cover 204 has an inclined sliding surface 203 and an inner sorting cover 202 inside. The inclined sliding surface 203 is located on the upper surface of the inner sorting cover 202. A sorting turntable is rotatably coupled to the middle of the inner sorting cover 202 via a sorting turntable bracket 220. 205, a central drive shaft 201 is fixedly installed in the middle of the sorting turntable 205, a drive gear ring support plate 206 is installed on the outer dust cover 204, a drive gear ring 208 is rotatably installed in the middle of the drive gear ring support plate 206, an electromagnet bracket 209 is fixedly installed on the drive gear ring 208, a plurality of electromagnets 207 are movably installed on the electromagnet bracket 209, a limiting shell 214 is fixedly installed on the drive gear ring support plate 206, a dust suction ring cover 213 is fixedly installed on the limiting shell 214, and a dust removal turntable 217 connected to the central drive shaft is provided on the inner side of the limiting shell 214.

[0032] An intermediate gear 210 and a drive gear 211 are rotatably mounted on the drive gear ring support plate 206. The drive gear 211 and the drive gear ring 208 are driven by the intermediate gear 210. A separate motor 212 is fixedly mounted on the dust collection ring cover 213. The output shaft of the separate motor 212 is connected to the drive gear 211 and is used to drive the drive gear 211 to rotate.

[0033] The dust collection ring cover 213 is also equipped with an exhaust port 2131, and a dust collection hose 3 is installed at the exhaust port 2131. The other end of the dust collection hose 3 is connected to the vacuum cleaner.

[0034] The sorting turntable 205 has multiple through holes along the radial direction, and the width of the through holes increases sequentially from the center of the sorting turntable 205 outwards.

[0035] The collecting unit 1 includes a collecting groove mounting base 101, which is fixedly mounted on a support frame 103. The collecting groove mounting base 101 is provided with multiple layers of annular collecting grooves 102. The number of layers of collecting grooves 102 is one more than the number of through holes. A drive motor 104 is fixedly mounted on the support frame 103. A hexagonal sleeve 105 is fixedly mounted on the output shaft of the drive motor 104. The hexagonal sleeve 105 and the bottom end of the central drive shaft 201 are axially slidingly engaged via a spline.

[0036] The top surface of the inner wall of the outer dust cover 204 is fixed to the slope sliding surface 203 by a connecting hanger 219, and the inner sorting cover 202 is fixedly fitted to the slope sliding surface 203.

[0037] The upper surface of the sorting turntable 205 is provided with multiple actuating strips to drive the solid material on the surface to rotate. A sealing strip is provided between two adjacent electromagnets 207. The sealing strip is in contact with the electromagnet 207 and is fixed on the electromagnet support 209. All the electromagnets 207 and the sealing strip form a circle.

[0038] The top end of the central drive shaft 201 is slidably coupled to the dust removal turntable 217 in an axial manner using a spline. A tension spring 218 is arranged around the central drive shaft 201, and the two ends of the tension spring 218 are fixed to the dust removal turntable 217 and the central drive shaft 201, respectively.

[0039] At least three bouncing wheel brackets 215 are fixedly installed on the inner side of the limiting housing 214. Each bouncing wheel bracket 215 is rotatably equipped with a bouncing wheel 216. Multiple bouncing protrusions 2171 that roll in cooperation with the bouncing wheel 216 are fixedly installed on the lower surface of the dust removal turntable 217. Multiple raised stripes are arranged radially on the upper surface of the dust removal turntable 217.

[0040] In practical use, the bulk of solid waste to be recycled is poured into the opening in the middle of the dust collection ring hood 213. The solid waste will then fall onto the dust collection turntable 217 (which needs to be rotating; therefore, the drive motor 104 needs to be running, and its output shaft will drive the dust collection turntable 217 to rotate via the central drive shaft 201). The rotating dust collection turntable 217 will cause the solid waste to rotate, and some solid waste that has not yet fallen onto the dust collection turntable 217 will be struck by the raised stripes on the turntable 217, causing it to fly up. During this process, the dust in the solid waste will disperse into the air. Then, start the vacuum cleaner connected to the suction hose 3. The vacuum cleaner will draw a negative pressure inside the suction ring cover 213, at which point the dust will be sucked away (into the vacuum cleaner to prevent pollution to the external environment; a bag filter can be used here). At the same time, as the dust removal disc 217 rotates, the jumping protrusion 2171 will continuously contact different jumping wheels 216. Due to the restriction of the jumping wheels 216 (cam engagement), the dust removal disc 217 will continuously jump along the axial direction. At this time, the solid waste that has fallen onto the dust removal disc 217 can continue to jump, thereby separating more dust mixed in with the solid waste.

[0041] Solid waste falling onto the dust collector turntable 217 will be thrown onto the inner side of the limiting shell 214 by the turntable 217, and then fall downwards. First, the electromagnet 207 needs to be energized. The energized electromagnet 207 generates magnetic force. During the downward fall of the solid waste, magnetic substances in the solid waste will be separated and attracted to the electromagnet 207, leaving only ordinary solid waste of varying sizes. The magnetic substances on the electromagnet 207 need to be cleaned periodically. The cleaning method is as follows: Start the separation motor 212. The output shaft of the separation motor 212 drives the drive gear 211 to rotate. The drive gear 211 rotates, which in turn drives the intermediate gear 210 to rotate. The intermediate gear 210 rotates, which in turn drives the drive gear ring 208 to rotate. The drive gear ring 208 rotates, which in turn drives the electromagnet support 209 to rotate. The electromagnet support 209 rotates, which in turn drives all the electromagnets 207 to rotate. At this time, the electromagnets 207 are subjected to centrifugal force and will fall downwards. Figure 10 The position shown swings to as Figure 11 The electromagnet 207 is positioned as shown (changing from vertical to horizontal). Then, the electromagnet 207 is de-energized, causing the magnetic material adsorbed on its surface to be flung off and separated from it. The separation motor 212 is then stopped, allowing the electromagnet 207 to reset. The flung magnetic material falls onto the surface of the ramp sliding surface 203. Since the machine itself is a vibrating device, the magnetic material on the ramp sliding surface 203 will slide into the outermost collection tank 102.

[0042] Solid waste not attracted by the electromagnet 207 will fall into the middle of the sorting turntable 205. The area in the middle of the sorting turntable 205, which has the same area as the dust removal turntable 217, has no through holes. It then rotates with the sorting turntable 205. The rotation of the sorting turntable 205 causes the solid waste on its surface to rotate, and then the solid waste is moved towards the edge by centrifugal force. Smaller diameter solid waste will fall directly into the inner collection tank 102, while larger diameter solid waste will fall into the outermost collection tank 102. The largest solid waste will rush out of the sorting turntable 205 and fall into the outermost innermost collection trough 102. After all the solid waste has been sorted, the hydraulic cylinder 4 is activated to lift the sorting section 2, and then all the solid waste in the collection troughs 102 can be removed. To facilitate continuous sorting, conveyor belts or conveying pipes can be set at corresponding positions to allow the sorted solid waste (those falling from the through holes of the sorting turntable 205 and those sliding down the surface of the ramp sliding surface 203) to be discharged sequentially. During the ascent of the sorting section 2, the bottom of the central drive shaft 201 will separate from the hexagonal sleeve 105, and during the descent, the bottom of the central drive shaft 201 will re-insert into the hexagonal sleeve 105.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
