Description

TECHNICAL FIELD

[0001] The present application relates to waste plastic floating material recycling production line, especially to a broken plastic pre-cleaning water circulation system. BACKGROUND

[0002] The waste plastic floating material recycling production line is mainly used for crushing, cleaning and recycling of industrial film, agricultural film, garbage film, PP woven bag and ton bag floating material. The main supporting equipment includes crushing equipment, cleaning equipment, dehydration equipment, rinsing equipment and drying equipment.

[0003] In the floating material rinsing and cleaning production system, the rinsing equipment is one of the essential main equipment in the waste plastic floating material recycling production line. The floating material after cleaning by the cleaning equipment is attached with stains dissolved by the cleaning agent, residual silt, powder and other impurities. The rinsing equipment rinses the cleaned floating material, which can make the floating material cleaner and improve the purity and processing performance of the floating material recycling material.

[0004] At present, the common rinsing equipment on the market includes a rinsing pool. The floating material is put into the floating material input area of the rinsing pool by manual or feeding equipment. A conveying device is arranged in the rinsing pool to convey the floating material floating upwards to the floating material output end of the rinsing pool. The conveying device includes a plurality of conveying levers. A plurality of teeth are arranged on the circumferential wall of each conveying lever. When each conveying lever rotates, the teeth move the floating material floating upwards to the floating material output end of the rinsing pool.

[0005] However, due to the strong wrapping property of the floating material and its own buoyancy, part of the floating material put into the floating material input area cannot fully expand and fully contact with the rinsing water in the rinsing pool, so that the stains dissolved by the cleaning agent, residual silt, powder and other impurities attached to the floating material are all rinsed off. Especially when the amount of floating material is large, part of the sludge and other impurities will be lifted by the floating material and cannot be separated from the floating material, so the rinsing effect is not very ideal.

[0006] In addition, for the rinsing water after rinsing, hereinafter referred to as sewage for convenience, such sewage contains stains dissolved by the cleaning agent, residual silt, powder and other impurities. If such sewage is directly discharged into the external environment, it will not only pollute the environment, but also cause serious waste of water resources. SUMMARY

[0097] As shown in Figure 12As shown, a bottom plate 9 is arranged in the box 6, and the rear part of the bottom plate 9 is an arc-shaped structure 901 which is attached to the two filter screen plates. A first arc-shaped partition plate is arranged on the bottom plate 9 and attached to the first filter screen plate 81, and a second arc-shaped partition plate 10 is arranged on the bottom plate 9 and attached to the second filter screen plate 82. Since the first filter screen plate 81 and the second filter screen plate 82 are symmetrically distributed relative to the center plane between them, the first arc-shaped partition plate and the second arc-shaped partition plate 10 are also symmetrically distributed relative to the center plane, and the structures of the two are the same.

[0098] As shown in Figure 10 , Figure 12 and Figure 13 , the bottom plate 9 located in front of the first arc-shaped partition plate and the second arc-shaped partition plate 10 extends to the left and right to form left and right extension bottom plates. A first partition plate 11 is arranged on the rear end of the left extension bottom plate, and the left and right sides of the first partition plate 11 are connected to the first arc-shaped partition plate and the left side wall 605 of the box, respectively. A second partition plate 12 is arranged on the rear end of the right extension bottom plate, and the left and right sides of the second partition plate 12 are connected to the second arc-shaped partition plate 10 and the right side wall 606 of the box, respectively.

[0099] The first partition plate 11, the left side wall 605 of the box, the front side wall 604 of the box, the right side wall 606 of the box, the second partition plate 12, and the bottom plate 9 enclose a water inlet cavity 13. At this time, the top of the water inlet cavity 13 is open, and the side wall of the water inlet cavity 13 is open at the gap 27 between the first partition plate 11 and the second partition plate 12, and the remaining areas are closed.

[0100] The water inlet pipe 601 is located on the front side wall 604 of the box. The first partition plate 11, the first arc-shaped partition plate, the first filter screen plate 81, the bottom plate 9, the rear side wall of the box, the second filter screen plate 82, the second arc-shaped partition plate 10, and the second partition plate 12 enclose a filter cavity 14. At this time, the top of the filter cavity 14 is open, and the side wall of the filter cavity 14 is open at the gap 27 between the first partition plate 11 and the second partition plate 12 and the slag outlet 18 described later, and the remaining areas are closed.

[0101] The water inlet cavity 13 communicates with the filter cavity 14 through the gap 27 between the first partition plate 11 and the second partition plate 12. The chamber in the box 6 outside the water inlet cavity 12 and the filter cavity 13 is a filtered water collection cavity 15. A clear water drain pipe 17 which communicates with the filtered water collection cavity 15 is arranged on the side wall of the box 6. The number of the clear water drain pipe 17 can be one or multiple. When the number of the clear water drain pipe 17 is multiple, a clear water drain valve is arranged corresponding to each clear water drain pipe 17, and the outlet of each clear water drain valve is connected to the inlet of the water storage tank 900.

[0102] As shown in Figure 12 and Figure 13As shown, a slag outlet 18 communicating with the filter chamber 14 is provided on the rear side wall of the housing 6, and a downwardly inclined discharge trough plate 19 is provided at the slag outlet 18. The area of ​​the rear side wall of the housing 6 from the slag outlet 18 to the bottom plate 9 and within the filter chamber 14 is an arc-shaped curved side wall 602 that fits against both the first filter screen plate 81 and the second filter screen plate 82.

[0103] A better solution is to directly form the rear sidewall of the housing 6, specifically the area where the base plate 9 contacts the rear sidewall, into an arc-shaped curved sidewall 602. Then, a cover 20 is hinged to the upper part of the rear sidewall of the housing 6. The cover 20 is also composed of an arc-shaped top plate 2001 and two side plates 2002. The cover 20 can be supported by a pair of hydraulic struts 21, allowing it to be in an upward-opening state during equipment use. A handle 2003 can also be provided on the cover 20 to facilitate the operator in opening or closing it.

[0104] like Figure 11 As shown, in this embodiment, the filter plate is composed of an inner fixing frame 801, a filter 802 and an outer fixing frame 803 stacked in sequence and connected by several fastening bolts; the inner fixing frame of the first filter plate 81 and the inner fixing frame of the second filter plate 82 are arranged facing each other.

[0105] The inner fixing frame 801 includes: a first central support ring 8011, a first outer support ring 8012, and a plurality of first central connecting plates 8013 connecting the first central support ring 8011 and the first outer support ring 8012. A plurality of reinforcing support plates 8014 are also provided between each pair of adjacent first central connecting plates 8013, with one end of each reinforcing support plate 8014 connected to the first central support ring 8011 and the other end of each reinforcing support plate 8014 connected to the first outer support ring 8002.

[0106] A more preferred approach is to have four first central connecting plates 8003, with each first central connecting plate 8003 evenly spaced circumferentially. Preferably, there are two reinforcing support plates 8014 between each pair of adjacent first central connecting plates 8013, with each reinforcing support plate 8014 evenly separating the areas between corresponding pairs of adjacent first central connecting plates 8013.

[0107] A better solution is to integrally form the first central support ring 8011, the first external support ring 8012, each first central connecting plate 8013, and each reinforcing support plate 8014.

[0108] The outer fixing frame 803 includes: a perforated plate 8031, a second central support ring 8032, a second outer support ring 8033, and a plurality of second central connecting plates 8034 connecting the second central support ring 8032 and the second outer support ring 8033. The number of each second central connecting plate 8034 is the same as that of each first central connecting plate 8013, and their positions also correspond one-to-one.

[0109] A more preferred embodiment is that the second central support ring 8032, the second outer support ring 8033, and the second central connecting plate 8034 are integrally formed. For ease of description, the plate integrally formed by the second central support ring 8032, the second outer support ring 8033, and the second central connecting plate 8034 is referred to as the outer connecting plate. The perforated plate 8031 ​​is located on the inner side of the outer connecting plate. When the inner fixing frame 801, the filter screen 802, and the outer fixing frame 803 are stacked in sequence and connected by several fastening bolts, the perforated plate 8031 ​​is sandwiched between the filter screen 802 and the outer connecting plate.

[0110] To improve the overall strength of the filter screen, several external reinforcing ribs can be installed on the outer fixing frame 803.

[0111] The first filter plate 81 is sealed with the first arc-shaped partition, the bottom plate 9, and the arc-shaped curved side wall 602 by a first soft sealing assembly; the second filter plate 82 is sealed with the second arc-shaped partition 10, the bottom plate 9, and the arc-shaped curved side wall 602 by a second soft sealing assembly.

[0112] by Figure 12 The orientation shown describes the water circulation process of the continuous filtration device 200 and the rinsing device 100. The rinsing water in the rinsing tank 1, which is pumped by the sludge pump 800, enters the inlet chamber 13 of the continuous filtration device 200 through the drain pipe 500 and the inlet pipe 601. Then, it enters the filter chamber 14 through the gap 27 between the first partition 11 and the second partition 12. The rotating shaft 7 rotates counterclockwise under the drive of the first drive device. The impurities are carried to the rear of the filter chamber 14 by the friction between the inner sidewalls of the first filter plate 81 and the second filter plate 82 and the impurities. As the rotating shaft 7 rotates, the impurities carried to the rear of the filter chamber 14 accumulate more and more. When the impurities accumulate to a certain extent, they can be discharged from the box 6 through the slag outlet 18. The clean water enters the filtered water collection chamber 15 through the filter holes on the first filter plate 81 and the second filter plate 82, and then is discharged into the water storage tank 900 through each clean water drain pipe 17. The clean water in the water storage tank 900 is drawn by the clean water pump 800 and returned to the rinsing tank 1 through the reuse pipe 700 to continue to be used for rinsing the floating material.

[0113] In the process of the impurities piling up at the rear of the filtering cavity 14, the impurities at the upper part of the pile are higher than the water level in the filtering cavity 14, so the impurities at the upper part of the pile are substantially equivalent to being filtered. Therefore, when the impurities drop into the discharge chute plate 19 through the slagging port 18 due to the high piling height, the impurities are very dry, which are called solid wastes. The dry solid wastes are beneficial to subsequent packaging, collection and recycling.

[0114] In addition, the continuous filtering device 200 with the above structure can continuously feed and continuously filter, thereby greatly improving the filtering efficiency.

[0115] In the operation process of the first filter screen plate 81 and the second filter screen plate 82, in order to prevent the filter holes on the filter screen 802 in the first filter screen plate 81 and the second filter screen plate 82 from being blocked by the impurities and affecting the filtering effect, as shown in Figure 10 、 Figure 12 、 Figure 13 and Figure 14 , a spraying system is further arranged in the box body 6. The spraying system is that a total spraying pipe 22 is fixedly arranged in the box body 6, one end of the total spraying pipe 22 is connected with a water pump, and a first branch spraying pipe 23 and a second branch spraying pipe 24 are arranged on the total spraying pipe 22.

[0116] The first branch spraying pipe 23 extends into the filtering cavity 14 and is located at the left side of the front half of the first filter screen plate 81, and a plurality of first spraying heads 25 which spray towards the first filter screen plate 81 are arranged on the first branch spraying pipe 23.

[0117] The second branch spraying pipe 24 extends into the filtering cavity 14 and is located at the right side of the front half of the second filter screen plate 82, and a plurality of second spraying heads 26 which spray towards the second filter screen plate 82 are arranged on the second branch spraying pipe 24.

[0118] In the operation process of the continuous filtering device 200, the rotating shaft 7 rotates in the counterclockwise direction as shown in Figure 12 , and when the first filter screen plate 81 and the second filter screen plate 82 are located at the area at the lower part, the impurities are brought to the rear of the filtering cavity 14 by the friction between the inner side wall and the impurities, and when the first filter screen plate 81 and the second filter screen plate 82 are located at the area of the spraying system, the impurities attached to the first filter screen plate 81 and the second filter screen plate 82 are washed away by the first spraying heads 25 and the second spraying heads 26, so that the filter holes on the first filter screen plate 81 and the second filter screen plate 82 are always unblocked, thereby greatly improving the filtering effect of the continuous filtering device.

[0128] A plurality of discharge poking plates 303 for poking the floating material at the discharge poking wheel 3 to the floating material output end are arranged on the circumferential wall of the discharge poking wheel 3. The discharge poking plates 303 adopt a mesh plate structure. The mesh plate structure is adopted to reduce the water amount carried by the floating material during the output of the floating material, and the two main purposes are to improve the subsequent dehydration efficiency of the floating material and to reduce the amount of rinsing water in the rinsing tank 1, thereby saving water and improving the utilization rate of water.

[0134] In addition, in order to improve the connection strength of each discharge paddle 303 to the discharge paddle wheel 3, as shown in Figure 2 , Figure 3 , Figure 4 and Figure 7 , a plurality of first reinforcing ribs 304 are arranged between each discharge paddle 303 and the circumferential wall of the discharge paddle wheel 3. The first reinforcing rib 304 can be a triangular reinforcing rib structure. More preferably, each first reinforcing rib 12 is uniformly spaced along the left and right directions of the corresponding discharge paddle 9.

[0138] As shown, the conveying levers 4 are supported on the rinsing tank 1 by the corresponding lever support bearing groups 401, and are arranged in uniform intervals from the rear side of the discharge roller 3 to the rear wall of the rinsing tank 1. The conveying levers 4 are driven by the corresponding third driving devices. The third driving devices can be third speed reducer motors 402.

[0139] In addition, in order to improve the connection strength of each conveying lever 4 on the corresponding conveying lever 4, as shown in Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, the conveying levers 4 are supported on the rinsing tank 1 by the corresponding lever support bearing groups 401, and are arranged in uniform intervals from the rear side of the discharge roller 3 to the rear wall of the rinsing tank 1.

[0140] As shown, the conveying levers 4 are supported on the rinsing tank 1 by the corresponding lever support bearing groups 401, and are arranged in uniform intervals from the rear side of the discharge roller 3 to the rear wall of the rinsing tank 1.

Figure 6 , Figure 7 and Figure 9As shown, the embodiment is provided with several residue discharge hoppers 102 at the bottom of the rinsing pool 1, and residue discharge valves are installed at the residue discharge ports at the bottom of each residue discharge hopper 102. The number of residue discharge hoppers 102 is determined according to the size of the rinsing pool 1, and when the number of residue discharge hoppers 102 is more than two, the residue discharge hoppers 102 are usually arranged from left to right. The sediment that sinks during the rinsing process is deposited in the residue discharge hoppers 102.

[0141] As shown, Figure 2 and Figure 9 As shown, the embodiment is provided with a discharge screw conveyor 5 at the front side of the rinsing pool 2, and the feeding port 501 of the discharge screw conveyor 5 is located at the top right side of the discharge screw conveyor 5, and the feeding port 501 of the discharge screw conveyor 501 can receive the floating material output from the floating material output end.

[0142] The discharge port 502 of the discharge screw conveyor 501 is located at the bottom left side of the discharge screw conveyor 5, and the discharge screw conveyor 5 is arranged in an inclined manner from the feeding port 501 to the discharge port 502, and the height of the discharge port 502 of the discharge screw conveyor 5 is higher than the height of the feeding port 501. Several drainage ports are provided at the bottom right side of the discharge screw conveyor 5, and a water filtering net is provided at each drainage port. At this time, when the discharge screw conveyor 5 is working, the floating material in the discharge screw conveyor 5 will be conveyed to the discharge port 502 along with the screw rod in the discharge screw conveyor 5, and part of the rinsing water entrained in the floating material will flow downward, and finally be discharged from each drainage port, which can further reduce the water content in the floating material.

[0143] The water discharged from each drainage port can also be recycled, and the drainage ports are connected to the rinsing pool 1 or the drainage pipeline 500 through a circulation pipeline.

[0144] The above rinsing equipment 100 uses a forced pressing method for feeding, and the floating material is forcedly pressed into the rinsing water in the rinsing pool 1 by the feeding screw conveyor. The floating material pressed into the bottom of the rinsing pool 1 is dispersed and floats upward under the action of the inclined forced pressing and its own characteristics. In the process of dispersion and upward floating, the floating material can unfold and fully contact with the rinsing water, so that the impurities such as the stains dissolved by the cleaning agent, the residual mud, and the powder adhered to the floating material will easily separate from the floating material, greatly improving the rinsing effect. The floating material floating in the rinsing water is sequentially hit and conveyed by each conveying paddle 403 from back to front, and the rinsing water forms a rolling water wave in the process of being hit and conveyed by each conveying paddle 403. The rolling water wave can play a role in rubbing the floating material, further improving the rinsing effect and making the rinsing more clean and thorough.

[0146] The system is additionally provided with a vibrating screen 300, as shown in the figure. Figure 1 The vibrating screen 300 is a prior art device and can be directly purchased, and the vibrating screen 300 is applied instead of being structurally designed, so the structure of the vibrating screen 300 is not described in detail.

[0147] A residue discharge screw conveyor 400 is arranged at each residue discharge port of the residue discharge hoppers 102, and each residue discharge port corresponds to one residue discharge screw conveyor 400 or is connected with the residue discharge inlet of the same residue discharge screw conveyor 400 after being collected. The screen 3001 of the vibrating screen 300 can receive the sediment output from the residue discharge outlet of the residue discharge screw conveyor 400, and the sediment is subjected to solid-liquid separation by the vibrating screen 300 to remove the excess water in the sediment. A sediment collecting tank 3002 can also be arranged at the sediment outlet of the vibrating screen 300.

[0148] The above description is only the preferred embodiment of the present application, and does not limit the present application in any other form, and any modification or equivalent change made according to the technical essence of the present application still falls within the scope of the present application.
