Description

Technical Field

[0001] The invention relates to the technical field of centrifuges, in particular to a centrifuge for processing building materials. Background Art

[0002] Building materials refer to all kinds of materials used in construction projects, including but not limited to ferrous metals, non-ferrous metals, natural stones, burnt earth products, cement concrete, synthetic polymer materials, asphalt and many other materials; among building materials, pipes are the most widely used, among which concrete pipes are important support and conveying materials. They can not only serve as the general support pipe for a number of pipelines, but also as a conveying pipeline for fluids such as water and oil. A centrifuge for concrete processing is a device used in the production of concrete products. It is mainly used to evenly distribute the concrete mixture in the mold through centrifugal force, while discharging excess water to improve the density and strength of the concrete. The centrifuges for building material processing in the prior art are usually unable to achieve fully automatic concrete casting and centrifugal operation, and are inconvenient to use. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is as follows: a centrifuge for processing building materials, comprising a main body mechanism for accommodating and driving the flow of concrete, the main body mechanism comprising a base frame, the main body mechanism being provided with a feeding mechanism for feeding concrete and a centrifugal mechanism for centrifuging concrete, the feeding mechanism comprising a rotating disk, the centrifugal mechanism comprising a motor, and the motor being fixedly mounted on the base frame; The main mechanism includes a fixed top frame fixedly mounted on the bottom frame, a vertical gear shaft rotatably mounted on the bottom frame, a bottom docking gear, a bottom transmission wheel, an upper gear and an upper bevel gear fixedly mounted on the vertical gear shaft, a rotating frame rotatably mounted on the bottom frame, a lifting column slidably mounted on the rotating frame, a lifting plate fixedly mounted on the lifting column, a top slide slidably mounted on the bottom frame, four mold modules are arranged on the rotating frame, and the mold module includes a swivel seat, and a swivel seat gear is fixedly mounted below the swivel seat.

[0004] Furthermore, the main mechanism also includes a cover seat fixedly installed under the top slide, a cover is rotatably installed under the cover seat, the top slide and the lifting column are rotatably installed, 121 is fixedly installed on the top slide, 121 is slidably installed with the fixed top frame, the rotating seat gear of the mold module located next to the bottom docking gear is meshed with the bottom docking gear, and a large gear ring is fixedly installed on the rotating frame.

[0005] Furthermore, the mold module includes two outer molds placed on a rotating seat, an inner mold is placed on the rotating seat, a keel is arranged outside the inner mold, and the two outer molds are fixed by a clamp.

[0006] During use, place the two outer molds into the turntable, and then place the inner mold and the keel into the turntable. Fix them with the clamp. When the outer mold and the inner mold are placed into the turntable, they will rotate together with the turntable. When the vertical gear shaft rotates, it will drive the turntable and the turntable gear of the mold module beside the bottom docking gear through the bottom docking gear, thereby driving the outer mold and the inner mold to rotate together, and cooperating with the reverse rotation of the discharge pipe and the central turntable to achieve uniform casting of concrete.

[0007] Further, the feeding mechanism includes an inner rotating gear and a central turntable fixedly installed on the rotating disk. The central turntable is provided with a discharge pipe. The rotating disk can rotate and slide relative to the fixed top frame. A steering gear is rotatably installed on the fixed top frame. The steering gear meshes with the upper gear. When the rotating disk descends, the steering gear meshes with the inner rotating gear. A flow pipe is fixedly installed on the fixed top frame. The flow pipe is communicated with the discharge pipe. A mixing cylinder is rotatably installed on the flow pipe.

[0008] Further, a bevel gear shaft is rotatably installed on the fixed top frame. A side bevel gear and a docking gear are fixedly installed on the bevel gear shaft. The side bevel gear meshes with the upper bevel gear. A mixing gear is fixedly installed on the mixing cylinder. The mixing gear meshes with the docking gear.

[0009] Further, a switch plate is slidably installed on the flow pipe. A ball is rotatably installed below the switch plate. The ball rolls on the rotating disk. A docking hole is provided on the switch plate.

[0010] Concrete enters from the mixing cylinder. In the initial state, the switch plate closes the flow pipe. The vertical gear shaft drives the side bevel gear, the bevel gear shaft and the docking gear to rotate through the upper bevel gear, thereby driving the mixing gear and the mixing cylinder to rotate to prevent the concrete in the mixing cylinder from solidifying. When the top carriage descends, the inner rotating gear, the central turntable, the discharge pipe and the switch plate descend under the action of gravity. The central turntable lands on the inner mold, and the discharge pipe reaches between the inner mold and the outer mold. The inner rotating gear meshes with the steering gear. The vertical gear shaft drives the steering gear to rotate through the upper gear, thereby driving the inner rotating gear, the central turntable and the discharge pipe to rotate. At the same time, the switch plate descends, so that the docking hole connects the flow pipe with the mixing cylinder. The concrete in the mixing cylinder enters between the inner mold and the outer mold through the flow pipe and the discharge pipe, and cooperates with the different-direction rotation of the discharge pipe and the turntable to achieve uniform casting of concrete.

[0011] Further, the centrifugal mechanism includes a motor gear fixedly installed on the motor shaft of the motor. An output wheel is rotatably installed on the chassis. An output gear is fixedly installed on the output wheel. The output gear meshes with the motor gear. A transfer wheel and an intermediate gear are rotatably installed on the chassis. An output belt is wound around the transfer wheel and the output wheel. A centrifugal gear is rotatably installed on the chassis. A lower transmission wheel is fixedly installed on the centrifugal gear. An outer transmission belt is wound around the lower transmission wheel, the bottom transmission wheel and the intermediate gear. The centrifugal gear meshes with the turret gear of the mold module located beside the centrifugal gear.

[0012] Further, a cylinder is fixedly installed on the chassis. A sliding block is fixedly installed on the output end of the cylinder. An outer sliding rod is slidably installed in the sliding block. A limiting rod is slidably installed in the outer sliding rod. A lifting slope block is fixedly installed on the outer sliding rod. A sliding groove is provided on the chassis. A sliding shaft is slidably installed in the sliding groove. A lower switching gear is rotatably installed on the sliding shaft. An upper switching gear is fixedly installed on the lower switching gear. The lower switching gear is located inside the limiting rod. An inner transmission belt is wound around the upper switching gear and the transfer wheel. The lifting slope block contacts the lifting disc. When the cylinder contracts to the closest end, the upper switching gear meshes with the large gear ring. When the cylinder extends to the farthest end, the lower switching gear meshes with the intermediate gear.

[0013] The motor drives the motor gear to rotate, thereby driving the output gear and the output wheel to rotate. The transfer wheel is driven to rotate through the output belt. The upper switching gear and the lower switching gear are driven to rotate through the inner transmission belt. When the cylinder retracts to the innermost end, the upper switching gear meshes with the large gear ring. The upper switching gear drives the large gear ring to rotate, thereby driving the rotating frame to rotate. At this time, the lifting slope block is located below the lifting disc, and the top sliding frame has not yet descended. Each time the rotating frame rotates 90 degrees, it drives the mold module to flow through each station. The mold module located below the rotating disc moves under the lid. The mold module located under the lid rotates 90 degrees and leaves under the lid. After removing the clamp, the two clamps can be opened and the inner mold can be taken out.

[0014] When the electric cylinder extends to the outermost end, in coordination with the sliding of the outer sliding rod and the sliding block, as well as the sliding of the limiting rod and the outer sliding rod, the limiting rod drives the sliding shaft to slide along the sliding groove, causing the upper switching gear to disengage from the large gear ring and the lower switching gear to engage with the intermediate gear. At the same time, the top slope block is lifted away from below the jacking disc, causing the top sliding frame to descend, and the lid to fall onto the outer mold. The lower switching gear drives the intermediate gear to rotate, driving the bottom driving wheel, vertical gear shaft, lower driving wheel, and centrifugal gear to rotate through the outer transmission belt. The number of teeth of the centrifugal gear is much larger than the module of the bottom docking gear, so the rotational speed of the mold module engaged with the centrifugal gear is much higher than that of the mold module engaged with the bottom docking gear. The centrifugal gear drives the outer mold and the inner mold of the mold module beside the centrifugal gear to rotate at high speed, achieving high-speed centrifugation. The turntable rotates rapidly to discharge the air bubbles in the concrete upward, reducing the bubbles to improve the strength of the building materials. The lid is used to prevent the concrete from being thrown out during high-speed centrifugation. When the electric cylinder retracts, the top slope block jacks up the jacking disc and the top sliding frame again.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: (1) The main mechanism set in the present invention transfers among the four mold modules during the feeding process, casting process, and centrifugation process, and cooperates to achieve automatic feeding, casting, capping, and centrifugation, with high automation and good continuity; (2) The feeding mechanism set in the present invention can automatically pour the concrete between the inner and outer molds when the centrifugation mechanism performs centrifugation on the concrete, and the inner and outer molds and the discharge pipe rotate in opposite directions during casting to improve the uniformity of casting; (3) The vertical gear shaft set in the present invention rotates continuously all the time, causing the mixing cylinder to rotate continuously to achieve continuous shaking of the concrete and prevent the concrete from solidifying when not being cast.

[0030] As Figures 2 - 4 shown, the mold module includes two outer molds 111 placed on the rotating base 108. An inner mold 113 is placed on the rotating base 108. A keel 112 is arranged outside the inner mold 113. The two outer molds 111 are fixed by a clamp 110.

[0031] During use, the two outer molds 111 are placed into the rotating base 108. Subsequently, the inner mold 113 and the keel 112 are placed into the rotating base 108. The two clamps 110 are fixed by the clamp 110. When the outer mold 111 and the inner mold 113 are placed into the rotating base 108, they will rotate together with the rotating base 108. When the vertical gear shaft 116 rotates, it will drive the rotating base 108 and the rotating base gear 109 of the mold module beside the bottom docking gear 117 to rotate through the bottom docking gear 117, thereby driving the outer mold 111 and the inner mold 113 to rotate together, and cooperating with the reverse rotation of the discharge pipe 204 and the central rotating base 203 to achieve uniform pouring of concrete.

[0035] Concrete enters from the mixing drum 209. In the initial state, the switch plate 207 closes the flow tube 205. The vertical gear shaft 116 drives the side bevel gear 213, the helical gear shaft 211 and the docking gear 212 to rotate through the upper bevel gear 120, thereby driving the mixing gear 210 and the mixing drum 209 to rotate to prevent the concrete in the mixing drum 209 from solidifying. When the top slide 102 descends, the inner rotating gear 202, the center rotating seat 203, the discharge pipe 204 and the switch plate 207 descend under the action of gravity, the center rotating seat 203 falls on the inner mold 113, and the discharge pipe 204 reaches the inner mold 113. Between the inner mold 111, the inner rotating gear 202 is meshed with the steering gear 214, and the vertical gear shaft 116 drives the steering gear 214 to rotate through the upper gear 119, thereby driving the inner rotating gear 202, the center rotating seat 203 and the discharge pipe 204 to rotate. At the same time, the switch plate 207 descends, so that the docking hole 208 connects the flow pipe 205 with the mixing drum 209, and the concrete in the mixing drum 209 enters between the inner mold 113 and the outer mold 111 through the flow pipe 205 and the discharge pipe 204, and cooperates with the different direction rotation of the discharge pipe 204 and the rotating seat 108 to achieve uniform casting of concrete.

[0036] like Figures 7 - 10As shown, the centrifugal mechanism includes a motor gear 302 fixedly mounted on the motor shaft of the motor 301, an output wheel 304 is rotatably mounted on the base frame 101, an output gear 303 is fixedly mounted on the output wheel 304, the output gear 303 is meshed with the motor gear 302, a rotating wheel 306 and an intermediate gear 316 are rotatably mounted on the base frame 101, an output belt 305 is wound around the rotating wheel 306 and the output wheel 304, a centrifugal gear 319 is rotatably mounted on the base frame 101, a lower transmission wheel 318 is fixedly mounted on the centrifugal gear 319, an outer transmission belt 317 is wound around the lower transmission wheel 318, the bottom transmission wheel 118 and the intermediate gear 316, and the centrifugal gear 319 is meshed with the rotating seat gear 109 of the mold module located next to the centrifugal gear 319.

[0037] like Figures 7 - 10 As shown, an electric cylinder 307 is fixedly installed on the base frame 101, a sliding block 308 is fixedly installed on the output end of the electric cylinder 307, an outer sliding rod 309 is slidably installed in the sliding block 308, a limit rod 311 is slidably installed in the outer sliding rod 309, a jacking slope block 310 is fixedly installed on the outer sliding rod 309, a sliding groove 320 is provided on the base frame 101, a sliding shaft 313 is slidably installed in the sliding groove 320, and a lower switching gear 310 is rotatably installed on the sliding shaft 313. 4. An upper switching gear 315 is fixedly mounted on the lower switching gear 314. The lower switching gear 314 is located on the inner side of the limit rod 311. An inner transmission belt 312 is wound around the upper switching gear 315 and the rotating wheel 306. The jacking ramp 310 is in contact with the jacking plate 105. When the electric cylinder 307 is retracted to the nearest end, the upper switching gear 315 is meshed with the large gear ring 107. When the electric cylinder 307 is extended to the farthest end, the lower switching gear 314 is meshed with the intermediate gear 316.

[0038] The motor 301 drives the motor gear 302 to rotate, thereby driving the output gear 303 and the output wheel 304 to rotate, and drives the intermediate wheel 306 to rotate through the output belt 305, and drives the upper switching gear 315 and the lower switching gear 314 to rotate through the inner transmission belt 312. When the electric cylinder 307 is recovered to the innermost end, the upper switching gear 315 is meshed with the large gear ring 107, and the upper switching gear 315 drives the large gear ring 107 to rotate, thereby driving the rotating frame 104 to rotate. At this time, the jacking ramp 310 is located below the jacking plate 105, and the top slide 102 has not yet descended. Each time the rotating frame 104 rotates ninety degrees, it drives the mold module to circulate in each station. The mold module located below the rotating plate 201 moves to below the cover 115, and the mold module located below the cover 115 rotates ninety degrees to leave below the cover 115. By removing the clamp 110, the two clamps 110 can be opened and the inner mold 113 can be pulled out.

[0039] When the electric cylinder 307 extends to the farthest end, in cooperation with the sliding of the outer sliding rod 309 and the sliding block 308 and the sliding of the limiting rod 311 and the outer sliding rod 309, the limiting rod 311 drives the sliding shaft 313 to slide along the sliding groove 320, so that the upper switching gear 315 disengages from the large gear ring 107, and the lower switching gear 314 meshes with the intermediate gear 316. At the same time, the top slope block 310 is lifted away from below the lifting disc 105, causing the top sliding frame 102 to descend, and the lid 115 to fall onto the outer mold 111. The lower switching gear 314 drives the intermediate gear 316 to rotate, and drives the bottom driving wheel 118, the vertical gear shaft 116, the lower driving wheel 318 and the centrifugal gear 319 to rotate through the outer transmission belt 317. The number of teeth of the centrifugal gear 319 is much larger than the module of the bottom docking gear 117. Therefore, the rotational speed of the mold module meshing with the centrifugal gear 319 is much higher than that of the mold module meshing with the bottom docking gear 117. The centrifugal gear 319 drives the outer mold 111 and the inner mold 113 of the mold module located beside the centrifugal gear 319 to rotate at high speed, realizing high-speed centrifugation. The turntable 108 rotates rapidly to discharge the air bubbles in the concrete upward, reducing the air bubbles to improve the strength of the building materials. The lid 115 is used to prevent the concrete from being thrown out during high-speed centrifugation. When the electric cylinder 307 retracts, the top slope block 310 jacks up the lifting disc 105 and the top sliding frame 102 again.

[0040] The working principle of a centrifuge for processing building materials disclosed by the present invention is as follows: During use, two outer molds 111 are placed into the turntable 108, and then the inner mold 113 and the keel 112 are placed into the turntable 108. The two clamps 110 are fixed by the clamp 110. When the outer mold 111 and the inner mold 113 are placed into the turntable 108, they will rotate together with the turntable 108. When the vertical gear shaft 116 rotates, it will drive the turntable 108 and the turntable gear 109 of the mold module beside the bottom docking gear 117 through the bottom docking gear 117, thereby driving the outer mold 111 and the inner mold 113 to rotate together. The motor 301 drives the motor gear 302 to rotate, thereby driving the output gear 303 and the output wheel 304 to rotate. The middle wheel 306 is driven to rotate through the output belt 305, and the upper switching gear 315 and the lower switching gear 314 are driven to rotate through the inner transmission belt 312. When the electric cylinder 307 retracts to the innermost end, the upper switching gear 315 meshes with the large gear ring 107, and the upper switching gear 315 drives the large gear ring 107 to rotate, thereby driving the rotating frame 104 to rotate. At this time, the jacking slope block 310 is located below the jacking disc 105, and the top sliding frame 102 has not yet descended. Each time the rotating frame 104 rotates 90 degrees, it drives the mold module to flow through each station. Concrete enters from the mixing cylinder 209. In the initial state, the switch plate 207 closes the flow pipe 205. The vertical gear shaft 116 drives the side bevel gear 213, the helical gear shaft 211, and the docking gear 212 to rotate through the upper bevel gear 120, thereby driving the mixing gear 210 and the mixing cylinder 209 to rotate, preventing the concrete in the mixing cylinder 209 from solidifying. When the electric cylinder 307 extends to the outermost end, in cooperation with the sliding of the outer slide bar 309 and the sliding block 308 and the sliding of the limiting rod 311 and the outer slide bar 309, the sliding shaft 313 is driven by the limiting rod 311 to slide along the chute 320, so that the upper switching gear 315 disengages from the large gear ring 107, and the lower switching gear 314 meshes with the intermediate gear 316. At the same time, the jacking slope block 310 leaves below the jacking disc 105, causing the top sliding frame 102 to descend. When the top sliding frame 102 descends, the inner rotating gear 202, the central turntable 203, the discharge pipe 204, and the switch plate 207 descend under the action of gravity. The central turntable 203 lands on the inner mold 113, and the discharge pipe 204 reaches between the inner mold 113 and the outer mold 111. The inner rotating gear 202 meshes with the steering gear 214. The vertical gear shaft 116 drives the steering gear 214 to rotate through the upper gear 119, thereby driving the inner rotating gear 202, the central turntable 203, and the discharge pipe 204 to rotate. At the same time, the switch plate 207 descends, causing the docking hole 208 to connect the flow pipe 205 with the mixing cylinder 209. The concrete in the mixing cylinder 209 enters between the inner mold 113 and the outer mold 111 through the flow pipe 205 and the discharge pipe 204. In cooperation with the different-direction rotation of the discharge pipe 204 and the turntable 108, uniform casting of concrete is achieved.The top carriage 102 descends, causing the lid 115 to fall onto the outer mold 111. The lower switching gear 314 drives the intermediate gear 316 to rotate, which drives the bottom drive wheel 118, the vertical gear shaft 116, the lower drive wheel 318, and the centrifugal gear 319 to rotate through the outer transmission belt 317. The number of teeth of the centrifugal gear 319 is much larger than the module of the bottom docking gear 117. Therefore, the rotational speed of the mold module meshing with the centrifugal gear 319 is much higher than that of the mold module meshing with the bottom docking gear 117. The centrifugal gear 319 drives the outer mold 111 and the inner mold 113 of the mold module beside the centrifugal gear 319 to rotate at high speed, achieving high-speed centrifugation. The turntable 108 rotates rapidly to discharge the air bubbles in the concrete upward, reducing the air bubbles to improve the strength of the building materials. The lid 115 is used to prevent the concrete from being thrown out during high-speed centrifugation. When the electric cylinder 307 retracts, it jacks up the slope block 310 to jack up the lifting plate 105 and the top carriage 102 again.
