Description

Technical Field

[0001] The invention relates to the technical field of debris filtering, and in particular to a fully automatic high-precision debris filtering device. Background Art

[0002] An underwater pelletizer is a device used to cut plastic materials into pellets, which is commonly used in the plastic processing industry. Compared with traditional air pelletizers, underwater pelletizers are characterized by cooling through water flow, which makes the cut plastic pellets more uniform, stable, and more complete in shape. However, after the water flow is used, it contains a large amount of plastic debris, which cannot be directly reused. The plastic debris in the water must be filtered before it can be used again; the debris filtering device in the prior art is usually unable to completely separate the plastic in the water, and is unable to separately recycle the separated plastic and water, resulting in poor treatment effect. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a fully automatic high-precision debris filtering device, comprising a filtering mechanism for filtering debris in water, the filtering mechanism comprising a shell, the filtering mechanism being provided with a discharge mechanism for discharging debris and a storage mechanism for storing filtered water, the discharge mechanism comprising a flushing water tank, a connecting plate being fixedly mounted on the flushing water tank, the connecting plate being fixedly mounted on the shell, and the storage mechanism comprising a water storage cylinder;

[0004] Furthermore, the filtering mechanism includes a rotating filter element rotatably mounted in the outer shell, an inner filter screen is fixedly mounted in the rotating filter element, a fan is fixedly mounted in the outer shell, the inner filter screen allows water to pass through, the fan is located above the flushing water tank, and an intermediate gear is rotatably mounted on the outer shell.

[0005] Furthermore, the filtering mechanism also includes a water inlet pipe rotatably installed in the rotating filter element, a closing shell is fixedly installed on the water inlet pipe, a downpipe is fixedly installed under the outer shell, a filter element gear is fixedly installed outside the rotating filter element, an end shell is fixedly installed on the water inlet pipe, and a water outlet trough is arranged on the lower half of the end shell.

[0006] Furthermore, a conveying blade shaft is rotatably installed in the downpipe, a conveying gear is fixedly installed on the conveying blade shaft, the intermediate gear is meshed with the conveying gear, the intermediate gear is meshed with the filter element gear, and the downpipe is connected to the water storage cylinder.

[0007] Furthermore, a closing column is slidably installed in the sewer pipe, a closing sheet is fixedly installed on the closing column, and a closing spring is arranged between the closing column and the sewer pipe.

[0008] The water containing plastic debris used by the underwater pelletizer is passed into the water inlet pipe, and then the water enters the rotating filter element. The rotation of the intermediate gear drives the filter element gear and the rotating filter element to rotate, and the intermediate gear drives the conveying gear and the conveying blade shaft to rotate. The water passes through the inner filter screen and enters the sewer pipe. The plastic debris in the water is blocked by the inner filter screen and cannot enter the sewer pipe. As the rotating filter element rotates, the inner filter screen is driven to rotate together. When the debris reaches the bottom of the fan together with the inner filter screen, the fan blows downward, blowing the debris on the inner filter screen onto the upslope surface, and the water entering the sewer pipe is transported toward the closing piece by the conveying blade shaft. When there is no water transported, the closing piece closes the sewer pipe. When the conveying blade shaft transports water toward the water storage cylinder, the water will push the closing piece and the closing column to slide, the closing spring is compressed, and the water enters the water storage cylinder for storage. The closing piece and the closing spring prevent the water in the water storage cylinder from flowing back into the sewer pipe.

[0009] Furthermore, the discharge mechanism includes an upslope surface arranged on the flushing water tank, a plurality of flushing holes and a plurality of return holes are arranged on the upslope surface, a slag discharge slope is arranged on the flushing water tank, a water pushing channel is arranged in the flushing water tank, the water pushing channel is connected with the flushing holes, a water level line is arranged in the flushing water tank, the flushing water tank is filled with water, and the water level is level with the water level line.

[0010] Furthermore, a motor is arranged next to the flushing water tank, a motor gear is fixedly installed on the motor shaft of the motor, a bottom gear shaft is rotatably installed on the flushing water tank, a middle gear, an end gear and a lower docking gear are fixedly installed on the bottom gear shaft, the lower docking gear is meshed with the intermediate gear, and a bottom transmission belt is wrapped around the motor gear and the middle gear.

[0011] Furthermore, two bidirectional threaded columns are rotatably installed on the flushing water tank, and a horizontal transmission belt is wrapped around the two bidirectional threaded columns. An upper gear is fixedly installed on the bidirectional threaded column on the side away from the motor, and a vertical transmission belt is wrapped around the upper gear and the end gear. A water pusher plate is slidably installed in the flushing water tank, and a convex ball is fixedly installed on the water pusher plate, and the convex ball slides in the threads of the bidirectional threaded column.

[0012] The motor drives the motor gear to rotate, which drives the middle gear, bottom gear shaft, lower docking gear and end gear to rotate through the bottom transmission belt, the lower docking gear drives the intermediate gear to rotate, the end gear drives the upper gear to rotate through the vertical transmission belt, and drives the two two-way threaded columns to rotate synchronously through the horizontal transmission belt. The rotation of the two-way threaded column drives the water pusher plate to slide along the flushing water tank through the convex ball, and the water in the flushing water tank is pushed toward the water pusher channel through the water pusher plate. The water is pushed into the water pusher channel and finally squeezed out from the flushing hole. The water squeezed out from the flushing hole flows with the debris that falls on the upslope surface, and the debris is discharged from the slag discharge slope. When the water flows to the return water hole, it drips into the flushing water tank for repeated use. Since the two-way threaded column is provided with a two-way thread, when the convex ball and the water pusher plate move to the innermost, they start to move outward, and reciprocate in this way, so as to realize continuous and intermittent squeezing of water from the flushing hole to flush the debris on the upslope surface into the slag discharge slope.

[0013] Furthermore, the storage mechanism includes a water outlet pipe fixedly installed on the water storage cylinder, a lifting column is slidably installed in the water storage cylinder, a floating plate is fixedly installed on the lifting column, a support frame is fixedly installed on the water storage cylinder, a top rotating rod is rotatably installed on the support frame, two waist holes are provided on the top rotating rod, a closing plate is slidably installed in the closing shell, the closing plate and the top rotating rod are rotatably installed through the waist holes, and the lifting column and the top rotating rod are rotatably installed through the waist holes.

[0014] The filtered water is stored in the water storage cylinder and can be taken out through the water outlet pipe. When the water level in the water storage cylinder rises, it will drive the floating plate and the lifting column to rise, thereby driving the top rotating rod to rotate, thereby driving the closing plate to drop. When the closing plate completely closes the water inlet pipe, external water can no longer enter the rotating filter element. When the water in the water storage cylinder is used, the floating plate and the lifting column drop, causing the closing plate to rise and the water inlet pipe to open again.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The filtering mechanism provided in the present invention can efficiently separate plastic debris in water. The setting of the inner filter screen makes the separation accuracy high. At the same time, the separated plastic debris enters the discharge mechanism, and the water enters the sewer pipe, so the separation effect is good; (2) The discharge mechanism provided in the present invention can continuously push out the plastic debris. During the pushing process, the water source used can be reused. At the same time, the power source for pushing out the debris is consistent with the power source for filtering, so the efficiency is high; (3) When the rotating filter element and the inner filter screen provided in the present invention carry the plastic debris to the bottom of the fan, the plastic debris on the inner filter screen is blown to the upslope surface of the flushing water tank by the fan, so that the separation is complete; (4) When the water in the storage mechanism provided in the present invention is stored to a certain amount, the water inlet pipe will be closed through the closing plate to prevent the water in the water storage cylinder from overflowing and causing waste.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] Example: Reference Figure 1-Figure 10 A fully automatic high-precision debris filtering device includes a filtering mechanism for filtering debris in water, the filtering mechanism includes a housing 101, the filtering mechanism is provided with a discharge mechanism for discharging debris and a storage mechanism for storing filtered water, the discharge mechanism includes a flushing water tank 201, a connecting plate 221 is fixedly mounted on the flushing water tank 201, the connecting plate 221 is fixedly mounted on the housing 101, and the storage mechanism includes a water storage cylinder 301;

[0029] The filtering mechanism includes a rotating filter element 102 rotatably mounted in the outer shell 101, an inner filter screen 114 is fixedly mounted in the rotating filter element 102, a fan 113 is fixedly mounted in the outer shell 101, the inner filter screen 114 allows water to pass through, the fan 113 is located above the flushing water tank 201, and an intermediate gear 111 is rotatably mounted on the outer shell 101.

[0030] like Figure 2-Figure 5 As shown, the filtering mechanism also includes a water inlet pipe 103 rotatably installed in the rotating filter element 102, a closing shell 104 is fixedly installed on the water inlet pipe 103, a downpipe 105 is fixedly installed below the outer shell 101, a filter element gear 112 is fixedly installed outside the rotating filter element 102, an end shell 115 is fixedly installed on the water inlet pipe 103, and a water outlet trough is provided in the lower half of the end shell 115.

[0031] like Figure 2-Figure 5 As shown, a conveying blade shaft 106 is rotatably installed in the downpipe 105, a conveying gear 107 is fixedly installed on the conveying blade shaft 106, an intermediate gear 111 is meshed with the conveying gear 107, the intermediate gear 111 is meshed with the filter element gear 112, and the downpipe 105 is connected to the water storage cylinder 301.

[0032] like Figure 2-Figure 5 As shown, a closing column 109 is slidably installed in the down pipe 105 , a closing piece 108 is fixedly installed on the closing column 109 , and a closing spring 110 is arranged between the closing column 109 and the down pipe 105 .

[0033] The water containing plastic debris used by the underwater pelletizer is passed into the water inlet pipe 103, and then the water enters the rotating filter element 102. The intermediate gear 111 rotates to drive the filter element gear 112 and the rotating filter element 102 to rotate. The intermediate gear 111 drives the conveying gear 107 and the conveying blade shaft 106 to rotate. The water passes through the inner filter screen 114 and enters the sewer pipe 105. The plastic debris in the water is blocked by the inner filter screen 114 and cannot enter the sewer pipe 105. As the rotating filter element 102 rotates, the inner filter screen 114 is driven to rotate together. When the debris reaches the fan 113 together with the inner filter screen 114 At the bottom, the fan 113 blows air downward, blowing the debris on the inner filter 114 onto the upslope surface 215, and the water entering the sewer pipe 105 is transported toward the closing piece 108 by the conveying blade shaft 106. When there is no water being transported, the closing piece 108 closes the sewer pipe 105. When the conveying blade shaft 106 transports water toward the water storage cylinder 301, the water pushes the closing piece 108 and the closing column 109 to slide, the closing spring 110 is compressed, and the water enters the water storage cylinder 301 for storage. The closing piece 108 and the closing spring 110 prevent the water in the water storage cylinder 301 from flowing back into the sewer pipe 105.

[0034] like Figure 6-Figure 8 As shown, the discharge mechanism includes an upslope surface 215 arranged on the flushing water tank 201, and a plurality of flushing holes 217 and a plurality of return water holes 216 are arranged on the upslope surface 215. A slag discharge slope 220 is arranged on the flushing water tank 201. A water pushing channel 218 is arranged in the flushing water tank 201, and the water pushing channel 218 is connected with the flushing holes 217. A water level line 219 is arranged in the flushing water tank 201. The flushing water tank 201 is filled with water, and the water level is level with the water level line 219.

[0035] like Figure 6-Figure 8 As shown, a motor 202 is arranged next to the flushing water tank 201, a motor gear 203 is fixedly mounted on the motor shaft of the motor 202, a bottom gear shaft 205 is rotatably mounted on the flushing water tank 201, a middle gear 206, an end gear 207 and a lower docking gear 212 are fixedly mounted on the bottom gear shaft 205, the lower docking gear 212 is meshed with the intermediate gear 111, and a bottom transmission belt 204 is wound around the motor gear 203 and the middle gear 206.

[0036] like Figure 6-Figure 8 As shown, two bidirectional threaded columns 210 are rotatably installed on the flushing water tank 201, and a horizontal transmission belt 211 is wrapped around the two bidirectional threaded columns 210. An upper gear 209 is fixedly installed on the bidirectional threaded column 210 on the side away from the motor 202, and a vertical transmission belt 208 is wrapped around the upper gear 209 and the end gear 207. A water pusher plate 213 is slidably installed in the flushing water tank 201, and a convex ball 214 is fixedly installed on the water pusher plate 213, and the convex ball 214 slides in the thread of the bidirectional threaded column 210.

[0037] The motor 202 drives the motor gear 203 to rotate, and drives the middle gear 206, the bottom gear shaft 205, the lower docking gear 212 and the end gear 207 to rotate through the bottom transmission belt 204. The lower docking gear 212 drives the intermediate gear 111 to rotate, and the end gear 207 drives the upper gear 209 to rotate through the vertical transmission belt 208, and drives the two bidirectional threaded columns 210 to rotate synchronously through the horizontal transmission belt 211. The rotation of the bidirectional threaded column 210 drives the water pusher plate 213 to slide along the flushing water tank 201 through the convex ball 214, and the water in the flushing water tank 201 is pushed toward the water pusher plate 213 through the water pusher plate 213. Pushed by channel 218, water is pushed into the water pushing channel 218 and finally squeezed out from the flushing hole 217. The water squeezed out from the flushing hole 217 flows together with the debris that falls on the upslope surface 215, and the debris is discharged from the slag discharge slope 220. When the water flows to the return water hole 216, it drips into the flushing water tank 201 for repeated use. Since the two-way threaded column 210 is provided with a two-way thread, when the convex ball 214 and the water pushing plate 213 move to the innermost, they start to move outward, and reciprocate in this way, so as to realize continuous and intermittent squeezing of water from the flushing hole 217 to flush the debris on the upslope surface 215 into the slag discharge slope 220.

[0038] like Fig. 9 , Fig.10 As shown, the storage mechanism includes a water outlet pipe 307 fixedly installed on the water storage cylinder 301, a lifting column 305 is slidably installed in the water storage cylinder 301, a floating plate 306 is fixedly installed on the lifting column 305, a support frame 303 is fixedly installed on the water storage cylinder 301, a top rotating rod 302 is rotatably installed on the support frame 303, two waist holes are provided on the top rotating rod 302, a closing plate 304 is slidably installed in the closing shell 104, the closing plate 304 and the top rotating rod 302 are rotatably installed through the waist holes, and the lifting column 305 and the top rotating rod 302 are rotatably installed through the waist holes.

[0039] The filtered water is stored in the water storage cylinder 301 and can be taken out through the water outlet pipe 307. When the water level in the water storage cylinder 301 rises, the floating plate 306 and the lifting column 305 will rise, thereby driving the top rotating rod 302 to rotate, thereby driving the closing plate 304 to descend. When the closing plate 304 completely closes the water inlet pipe 103, external water can no longer enter the rotating filter element 102. When the water in the water storage cylinder 301 is used, the floating plate 306 and the lifting column 305 descend, thereby causing the closing plate 304 to rise and the water inlet pipe 103 to open again.

[0040] The working principle of the fully automatic high-precision debris filtering device disclosed in the present invention is as follows: the motor 202 drives the motor gear 203 to rotate, and drives the middle gear 206, the bottom gear shaft 205, the lower docking gear 212 and the end gear 207 to rotate through the bottom transmission belt 204, and the lower docking gear 212 drives the intermediate gear 111 to rotate, and the water containing plastic debris used by the underwater pelletizer is passed into the water inlet pipe 103, and then the water enters the rotating filter element 102, and the intermediate gear 111 rotates to drive the filter element gear 112 and the rotating filter element 102 to rotate, and the intermediate gear 111 drives the conveying gear 107 and the conveying blade shaft 106 to rotate, and the water enters the sewer pipe 105 through the inner filter screen 114, and the plastic debris in the water is blocked by the inner filter screen 114 and cannot enter. In the downpipe 105, as the rotating filter element 102 rotates, the inner filter screen 114 is driven to rotate together. When the debris arrives under the fan 113 together with the inner filter screen 114, the fan 113 blows air downward to blow the debris on the inner filter screen 114 onto the upslope surface 215. The water entering the downpipe 105 is transported toward the closing piece 108 by the conveying blade shaft 106. When there is no water being transported, the closing piece 108 closes the downpipe 105. When the conveying blade shaft 106 transports water toward the water storage cylinder 301, the water pushes the closing piece 108 and the closing column 109 to slide, the closing spring 110 is compressed, and the water enters the water storage cylinder 301 for storage. The closing piece 108 and the closing spring 110 prevent the water in the water storage cylinder 301 from flowing back into the downpipe 105. The end gear 207 drives the upper gear 209 to rotate through the vertical transmission belt 208, and drives the two bidirectional threaded columns 210 to rotate synchronously through the horizontal transmission belt 211. The rotation of the bidirectional threaded column 210 drives the water push plate 213 to slide along the flushing water tank 201 through the convex ball 214, and the water in the flushing water tank 201 is pushed toward the water push channel 218 through the water push plate 213. The water is pushed into the water push channel 218 and finally squeezed out from the flushing hole 217. The squeezed water flows with the debris that falls on the upslope surface 215, and the debris is discharged from the slag discharge slope 220. When the water flows to the return water hole 216, it drips into the flushing water tank 201 for repeated use. Since the two-way threaded column 210 is provided with a two-way thread, when the convex ball 214 and the water push plate 213 move to the innermost part, they start to move outward, and reciprocate in this way, so as to continuously and intermittently squeeze out water from the flushing hole 217 to flush the debris on the upslope surface 215 into the slag discharge slope 220. The filtered water is stored in the water storage cylinder 301 and can be taken out through the water outlet pipe 307. When the water level in the water storage cylinder 301 rises, the floating plate 306 and the lifting column 305 will rise, thereby driving the top rotating rod 302 to rotate, thereby driving the closing plate 304 to descend. When the closing plate 304 completely closes the water inlet pipe 103, external water can no longer enter the rotating filter element 102. When the water in the water storage cylinder 301 is used, the floating plate 306 and the lifting column 305 descend, thereby causing the closing plate 304 to rise and the water inlet pipe 103 to open again.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the protection scope of the present invention.
