Description

Technical Field

[0001] The invention relates to a production line for recycling and reusing floating waste plastics, in particular to a pre-cleaning water circulation system for crushed plastics. Background Art

[0002] The waste plastic floating material recycling and reuse production line is mainly used for crushing, cleaning, regenerating and recycling floating materials such as industrial films, agricultural films, garbage films, PP woven bags, and ton bags. The main supporting equipment includes crushing equipment, cleaning equipment, dehydration equipment, rinsing equipment, drying equipment, etc.

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

[0004] At present, common rinsing equipment on the market includes: a rinsing tank, in which floating materials are put into the floating material input area of the rinsing tank manually or by feeding equipment, and a conveying device is provided in the rinsing tank to transport the floating materials to the floating material output end of the rinsing tank. The conveying device includes: a plurality of conveying levers, and a plurality of teeth are provided on the circumferential wall of each conveying lever. When each conveying lever rotates, the floating materials are moved by each tooth to be transported toward the floating material output end of the rinsing tank.

[0005] However, due to the strong wrapping of the floating material and its own buoyancy, some of the floating material put into the floating material input area cannot be fully expanded and fully contacted with the rinsing water in the rinsing tank, and the stains dissolved by the detergent, residual mud, sand, powder and other impurities on the floating material are all rinsed away. Especially when the amount of floating material input is large, some sludge and other impurities will be lifted by the floating material and cannot be separated from the floating material, resulting in a not very ideal rinsing effect.

[0006] In addition, the rinse water after rinsing is referred to as sewage for the convenience of description. This type of sewage contains stains dissolved by the detergent, residual mud, sand, powder and other impurities. If this type of sewage is discharged directly into the external environment, it will not only pollute the environment, but also cause serious waste of water resources. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a crushed plastic pre-cleaning water circulation system which has a compact structure, is easy to operate, has a good rinsing effect and can continuously filter and recycle the rinsing water after rinsing.

[0008] In view of the characteristics of the floating material itself and the problems of poor rinsing and unsatisfactory treatment of rinse water after rinsing in the current common rinsing equipment, the present invention designs a forced material pressing method to improve the rinsing effect of the rinsing equipment, and designs a continuous filtration equipment to treat and recycle the sewage discharged from the rinsing equipment, thereby avoiding pollution to the environment and improving the utilization rate of water resources.

[0010] At least one slag discharge hopper is provided at the bottom of the rinsing tank, and a slag discharge port is provided on each slag discharge hopper; the above-mentioned rinsing water discharge port can be provided on the slag discharge hopper. When the number of slag discharge hoppers is greater than or equal to 2, each slag discharge hopper has a corresponding rinsing water discharge port, and each rinsing water discharge port is connected to the drainage pipe through a branch pipe.

[0011] Currently, there are various structures and models of filtration equipment used for sewage treatment on the market. This solution designs a continuous filtration device for rinsing equipment sewage treatment based on the characteristics of rinse water after rinsing. The structure of the continuous filtration device includes: a box and a filter structure; The filter structure includes: a rotating shaft, both ends of which are supported in a housing by a rotating shaft support bearing assembly, and the rotating shaft is driven to rotate by a first driving device; two disc-shaped filter plates are fixedly arranged on the rotating shaft at intervals: a first filter plate and a second filter plate; A bottom plate is provided in the box body, and the rear portion of the bottom plate is an arc-shaped structure fitted with two filter plates; a first arc-shaped partition fitted with the first filter plate and a second arc-shaped partition fitted with the second filter plate are provided on the bottom plate; the bottom plate located in front of the first arc-shaped partition and the second arc-shaped partition extends to the left and right sides respectively to form a left extended bottom plate and a right extended bottom plate; a first partition is provided on the rear end of the left extended bottom plate, and the left and right sides of the first partition are respectively connected to the first arc-shaped partition and the left side wall of the box body; a second partition is provided on the rear end of the right extended bottom plate, and the left and right sides of the second partition are respectively connected to the second arc-shaped partition and the right side wall of the box body; The first partition, the left side wall of the box, the front side wall of the box, the right side wall of the box, the second partition, and the bottom plate form a water inlet chamber, and the water inlet pipe is located on the front side wall of the box; at this time, the top of the water inlet chamber is open, and the side walls of the water inlet chamber are open at the gap between the first partition and the second partition, and the rest of the areas are closed.

[0012] The first partition, the first curved partition, the first filter plate, the bottom plate, the rear side wall of the box, the second filter plate, the second curved partition, and the second partition form a filter chamber; at this time, the top of the filter chamber is open, and the side walls of the filter chamber are open at the gap between the first partition and the second partition and at the slag outlet described later, and the rest of the areas are closed.

[0013] The water inlet chamber is connected to the filter chamber through the gap between the first partition plate and the second partition plate. The chamber inside the box located outside the water inlet chamber and the filter chamber is a filtered water collection chamber. Impurities in the sewage entering the filter chamber are retained in the filter chamber, while water is filtered into the filtered water collection chamber through the first filter plate and the second filter plate; a clean water drain pipe connected to the filtered water collection chamber is provided on the side wall of the box body, and the number of the clean water drain pipe is at least one, and each clean water drain pipe is correspondingly provided with a clean water drain valve, and the outlet of each clean water drain valve is connected to the inlet of the water storage tank; A slag outlet communicating with the filter cavity is provided on the rear side wall of the box body; The rear side wall area of the box body from the slag outlet to the bottom plate and located in the filter cavity is an arc-shaped curved side wall that fits both the first filter plate and the second filter plate.

[0014] The water circulation process of the continuous filtering equipment and rinsing equipment is as follows: the rinsing water in the rinsing tank pumped by the sludge pump enters the water inlet chamber through the drainage pipe, and then enters the filter chamber through the gap between the first partition plate and the second partition plate. The rotating shaft rotates under the drive of the first driving device, and relies on the friction between the inner side walls of the first filter plate and the second filter plate and the impurities to carry the impurities to the rear of the filter chamber. As the rotating shaft rotates, the impurities brought to the rear of the filter chamber accumulate more and more. When the impurities accumulate to a certain extent, the impurities can be discharged from the box through the slag outlet; and the clean water enters the filtered water collecting chamber through the filter holes on the first filter plate and the second filter plate, and then is discharged into the water storage tank through the clean water drainage pipes. The clean water in the water storage tank pumped by the clean water pump returns to the rinsing tank through the return pipe and continues to be used for rinsing the floating material.

[0015] Furthermore, in the aforementioned crushed plastic pre-cleaning water circulation system, the filter plate is composed of an inner fixing frame, a filter screen, and an outer fixing frame stacked in sequence and connected by a plurality of fastening bolts; wherein the filter screen performs a filtering function, and the inner fixing frame and the outer fixing frame support the filter screen, allowing the filter screen to be fully expanded and increasing the service life of the filter screen; the inner fixing frame of the first filter screen plate and the inner fixing frame of the second filter screen plate are arranged face to face; The first filter plate is sealed with the first arc-shaped partition plate, the bottom plate, and the arc-shaped curved side wall by a first soft sealing component; the second filter plate is sealed with the second arc-shaped partition plate, the bottom plate, and the arc-shaped curved side wall by a second soft sealing component.

[0016] Among them, the soft seal component belongs to the conventional seal component. Here, only soft seals are applied, rather than structural design of the soft seals. The soft seal's own soft characteristics make it suitable for sealing between moving and static components, and the sealing performance is relatively good, which can effectively prevent impurities and the like from leaking between the moving and static components. In this solution, the moving parts are the first filter plate and the second filter plate when the shaft rotates. For the first filter plate, the static parts are the first arc-shaped partition plate, bottom plate and arc-shaped curved side wall surrounding the first filter plate; for the second filter plate, the static parts are the second arc-shaped partition plate, bottom plate and arc-shaped curved side wall surrounding the second filter plate.

[0017] During use, the filter holes on the filter plate are easily clogged by impurities, affecting the filtering effect. Therefore, this solution also provides a spray system in the box to ensure that the filter holes on the filter plate are always in a smooth state through the spray system.

[0018] The spray system described in this solution is as follows: a main spray pipe is fixedly arranged in the box, one end of the main spray pipe is connected to a water pump, and a first branch spray pipe and a second branch spray pipe are arranged on the main spray pipe; The first branch spray pipe extends into the filter cavity and is located at the left side of the front half of the first filter plate.

The second branch spray pipe extends into the filter cavity and is located at the right side of the front half of the second filter plate. A plurality of second spray heads spraying toward the second filter plate are provided on the second branch spray pipe. During the operation of the continuous filtration equipment, each first spray head and each second spray head is also in a spraying state. The spraying state can be continuous or intermittent, and is adjusted according to actual needs. It is not required here.

[0019] Furthermore, in the aforementioned crushed plastic pre-cleaning water circulation system, the rinsing tank is a rectangular box structure; The feeding device is a feeding screw conveyor, and the discharge end of the feeding screw conveyor is sealed and passes through the mounting hole on the rear side wall of the rinsing tank and then extends into the rinsing tank; The feeding screw conveyor is arranged in an inclined direction from the feeding end to the discharging end, and the height of the discharging end of the feeding screw conveyor is lower than the height of the feeding end; The inclination angle α of the feed screw conveyor relative to the horizontal plane is 30 to 40 degrees.

[0020] The floating material is pressed obliquely into the bottom of the rear part of the rinsing tank by the feeding screw conveyor.

[0021] Furthermore, in the aforementioned crushed plastic pre-cleaning water circulation system, the conveying device comprises: a discharge dial wheel and a plurality of conveying dial rods; The discharging thumbwheel is fixed on a wheel shaft, and the wheel shaft is supported by a wheel shaft support bearing group and is arranged on the rinsing tank and is located at the rear side of the floating material output end; the wheel shaft is driven to rotate by a second driving device; a plurality of discharging paddles are provided on the circumferential wall of the discharging thumbwheel to paddle the floating material at the discharging thumbwheel to the floating material output end, and the discharging paddles are mesh plate structures; Each conveying lever is supported on the rinsing tank by its corresponding lever support bearing group, and is evenly spaced from the rear side of the discharge wheel to the rear side wall of the rinsing tank; each conveying lever is driven by its corresponding third drive device; a plurality of conveying plates are provided on the circumferential wall of the conveying lever to convey the material located at the corresponding conveying lever forward; when each conveying lever rotates, each conveying plate beats and conveys the floating material forward.

[0022] Furthermore, in the aforementioned crushed plastic pre-cleaning water circulation system, the discharge plates are divided into two groups, one group being a left discharge plate group and the other group being a right discharge plate group; Each of the discharge paddle plates in the left discharge paddle plate group is located on the left half of the circumferential wall of the discharge paddle wheel, and each of the discharge paddle plates in the left discharge paddle plate group is evenly spaced and arranged in sequence along the circumference of the discharge paddle wheel; Each of the discharge paddle plates in the right discharge paddle plate group is located on the right half of the circumferential wall of the discharge paddle wheel, and each of the discharge paddle plates in the right discharge paddle plate group is evenly spaced and arranged in sequence along the circumference of the discharge paddle wheel; The discharging plates in the left discharging plate group and the discharging plates in the right discharging plate group are arranged alternately in sequence, and the length of each discharging plate is greater than half the length of the discharging wheel; A plurality of first reinforcing ribs are arranged between each discharge dial plate and the circumferential wall of the discharge dial wheel.

[0023] Furthermore, in the aforementioned crushed plastic pre-cleaning water circulation system, the conveying plates are evenly spaced and arranged in sequence along the circumference of the corresponding conveying rod; The conveying plate includes: an inner partition plate connected to the circumferential wall of the corresponding conveying lever, a middle partition plate inclined relative to the inner partition plate, and an outer partition plate inclined relative to the middle partition plate, and the inclination direction of the middle partition plate and the outer partition plate are opposite to the rotation direction of the corresponding conveying lever, and the inner partition plate, the middle partition plate, and the outer partition plate are integrally formed; A plurality of second reinforcing ribs are provided between each conveying plate and the circumferential wall of the corresponding conveying rod.

Each of the drain outlets is connected to the rinsing tank or the drainage pipeline through a circulation pipeline.

[0026] The beneficial effects of the present invention are as follows: ① The continuous filtering equipment in the above-mentioned crushed plastic pre-cleaning water circulation system relies on the friction between the inner wall of the first filter plate and the second filter plate and the impurities to bring the impurities to the rear of the filter chamber, and the filtered water is discharged out of the box through the filtered water collection chamber and the drainage pipes; as the rotating shaft rotates, the impurities brought to the rear of the filter chamber accumulate more and more, and when the impurities accumulate to a certain extent, the impurities can be discharged out of the box through the slag outlet, and the controlled water level is lower than the slag outlet, so the impurities accumulated at the slag outlet will be filtered very dry, and the dry impurities are conducive to the subsequent Continue to pack, collect and recycle; in addition, the continuous filtration equipment can continuously feed and filter, which greatly improves the filtration efficiency; ② The rinsing equipment in the above-mentioned crushed plastic pre-cleaning water circulation system adopts a forced pressing method to feed, and the floating material is forced into the rinsing water. At this time, the floating material is dispersed and floated upward under its own characteristics and the action of inclined forced pressing. In the process of dispersion and floating, the floating material can be expanded and fully contacted with the rinsing water. Therefore, the impurities such as stains dissolved by the cleaning agent, residual mud, sand, powder, etc. attached to the floating material will be easily separated from the floating material, which greatly improves the rinsing effect. In addition, the floating materials that float up are beaten and conveyed forward by each conveying paddle. In the process of beating and conveying forward by each conveying paddle, the rinsing water will form undulating waves, which can scrub the floating materials and further improve the rinsing effect, making the rinsing cleaner and more thorough. ③ The rinsing water in the rinsing tank is filtered by continuous filtration equipment, and the clean water obtained by filtration is sent back to the rinsing tank to continue to participate in the rinsing operation, which can not only solve the pollution caused by the direct discharge of sewage into the environment, but also realize the recycling of water, greatly improving the utilization rate of water resources.

[0042] The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings and preferred embodiments. However, the exemplary embodiments may be embodied in various forms and should not be construed as being limited to the embodiments described herein. Rather, these embodiments are provided to make this disclosure thorough and complete and to enable those skilled in the art to fully understand the scope of this disclosure.

[0043] In the absence of conflict, the various embodiments of the present disclosure and the various features therein may be combined with each other.

[0044] For the convenience of describing the rinsing device 100, the "left", "right", "front" and "back" directions of the rinsing device 100 are defined as follows: Figure 6 The left-hand direction shown is defined as "front", with Figure 6 The right-hand direction shown is defined as "rear", with Figure 9 The left-hand direction shown is defined as "right", with Figure 9 The right-hand direction shown is defined as "left", and all directional words involved in describing the rinsing device in the present invention are based on the above definition.

[0045] For the convenience of describing the continuous filtering device 200, the "left", "right", "front" and "back" directions of the continuous filtering device 200 are defined as follows: Figure 12 The left-hand direction shown is defined as "front", with Figure 12 The right-hand direction shown is defined as "rear", with Figure 13 The left-hand direction shown is defined as "right", with Figure 13The right-hand side direction shown is defined as "left", and all directional words involved in describing the continuous filtration device in the present invention are based on the above definition.

[0046] When the rinsing equipment 100 and the continuous filtering equipment 200 are placed in an actual factory, their relative positions are not fixed and need to be adjusted according to the actual installation area of the factory and the location of the connecting equipment of the previous and next processes.

Figure 12 and attached Figure 13 The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation; therefore, it cannot be understood as a limitation on the positions of both the rinsing device 100 and the continuous filtration device 200. Example 1

[0047] A crushed plastic pre-cleaning water circulation system described in this embodiment, such as Figure 1 、 Figure 2 and Figure 6 As shown, it comprises: a rinsing device 100 and a continuous filtering device 200. The rinsing device 100 comprises: a rinsing tank 1, and the rinsing tank 1 is usually placed on a second frame 101.

[0048] A rinsing water outlet 104 is provided on the rinsing tank 1 , and a drain valve is installed at the rinsing water outlet 104 ; a rinsing water reuse port 105 is provided on the rinsing tank 1 , and a reuse valve is installed at the rinsing tank reuse port 105 .

[0049] The outlets of each drain valve on the rinsing tank 1 are connected to the water inlet pipe 601 of the continuous filtering equipment 200 through the drainage pipe 500, and a sludge pump 600 is installed on the drainage pipe 500; the rinsing water in the rinsing tank 1 enters the continuous filtering equipment 200 through the drainage pipe 500 under the action of the sludge pump 600 for filtration.

[0050] A clean water drain valve is provided on the clean water drain pipe 17 of the continuous filtering device 200, and the outlet of the clean water drain valve is connected to the inlet of the water storage tank 900. The outlet of the water storage tank 900 is connected to the inlet of the reuse valve on the rinsing tank 1 through the reuse pipeline 700, and a clean water pump 800 is provided on the reuse pipeline 700; the clean water obtained after the rinsing water is filtered by the continuous filtering device 200 is stored in the water storage tank 900, and the clean water in the water storage tank 900 is returned to the rinsing tank 1 through the reuse pipeline 700 under the action of the clean water pump 800 to continue to participate in the rinsing operation. This method can greatly save the use of rinsing water and improve the utilization rate of water resources.

[0051] In order to make the overall structure more compact, the water tank 900 and the continuous filtering device 200 can both be installed on the first frame 9001, and the continuous filtering device 200 is located above the water tank 900.

[0052] A liquid level meter or liquid level sensor may also be provided in the rinsing tank 1 for real-time monitoring of the liquid level of the rinsing water in the rinsing tank 1. The drain valve, reuse valve, and clean water drain valve may be valves with signal receiving control, and a control device may be provided. The drain valve, reuse valve, clean water drain valve, or liquid level sensor may be connected to the control device for signal communication. The program programmed in the control device monitors the water level in the rinsing tank 1 and controls the opening and closing of the drain valve, reuse valve, and clean water drain valve, as well as the size of their openings, so that the continuous filtration device 200 and the rinsing device 100 can automatically coordinate their operations.

[0053] At least one slag discharge hopper 102 is provided at the bottom of the rinsing tank 1 , and each slag discharge hopper 102 is provided with a slag discharge port.

[0054] The above-mentioned rinsing water outlet 104 can be set on the slag hopper 102. When the number of slag hoppers 102 is greater than or equal to 2, each slag hopper 102 has a corresponding rinsing water outlet 104, and each rinsing water outlet 104 is connected to the drainage pipeline 500 through a branch pipeline.

[0055] A feeding device 2 for forcibly pressing the floating material into the rinsing tank 1 is provided on the rear side of the rinsing tank 1. The material is forcibly pressed into the rinsing water of the rinsing tank 1 by the feeding device 2. The floating material can expand and contact with the rinsing water during the process of floating up under the action of its own buoyancy. Compared with the floating material directly put into the rinsing tank 1, the floating material expands more, the contact area with the rinsing water is larger, and the contact and flushing is more sufficient. It also avoids the defect that some impurities such as sludge are lifted by the floating material and cannot contact with the rinsing water due to being directly put into the rinsing tank. Therefore, impurities such as stains dissolved by the detergent, residual mud, sand, powder, etc. attached to the floating material will be easily separated from the floating material, thereby greatly improving the rinsing effect.

[0056] The front top of the rinsing tank 1 is a floating material output end. A conveying device is provided in the rinsing tank 1 to convey the floating material to the floating material output end. The rinsed floating material is output outside the rinsing tank 1 through the conveying device.

[0057] The above system filters the rinsing water in the rinsing tank 1 through the continuous filtration equipment 200, and the clean water obtained by filtration is sent back to the rinsing tank 1 to continue to participate in the rinsing operation. It can not only solve the pollution caused by directly discharging sewage into the environment, but also realize the recycling of water, greatly improving the utilization rate of water resources.

[0058] Example 2 For the convenience of description, the rinse water after rinsing is referred to as sewage. This type of sewage contains impurities such as stains dissolved by the cleaning agent, residual mud, sand, powder, etc. If this type of sewage is discharged directly into the external environment, it will not only pollute the environment, but also cause serious waste of water resources. Therefore, it is necessary to filter the sewage to separate the impurities in the sewage from the water. The separated impurities are usually called solid waste. However, the solid waste obtained by filtering the sewage through the filtering equipment currently available on the market has a high water content that can be seen with the naked eye. It is relatively wet as a whole, which is not conducive to the recycling of solid waste. In view of this situation, this embodiment designs a continuous filtering device 200 based on the first embodiment.

[0059] like Figure 10 As shown, the structure of the continuous filtration device 200 of the present invention includes a housing 6 and a filter structure. The filter structure includes a rotating shaft 7, supported within the housing 6 at both ends by a rotating shaft support bearing assembly 701. The rotating shaft 7 is driven by a first drive device, which can be a first reduction motor 603. Two disc-shaped filter plates are fixedly mounted on the rotating shaft 7, spaced apart from each other. From left to right, the two filter plates are a first filter plate 81 and a second filter plate 82.

[0060] like Figure 12 As shown, a bottom plate 9 is provided in the box body 6, and the rear part of the bottom plate 9 is an arc-shaped structure 901 fitted with two filter plates; a first arc-shaped partition plate fitted with the first filter plate 81 and a second arc-shaped partition plate 10 fitted with the second filter plate 82 are provided on the bottom plate 9; because the first filter plate 81 and the second filter plate 82 are symmetrically distributed relative to the center plane therebetween, the first arc-shaped partition plate and the second arc-shaped partition plate 10 are also symmetrically distributed relative to the above-mentioned center plane, and the structures of the two are also the same.

[0061] like Figure 10 、 Figure 12 and Figure 13As shown, the bottom plate 9 located in front of the first curved partition plate and the second curved partition plate 10 extends to the left and right sides respectively to form a left extended bottom plate and a right extended bottom plate; a first partition plate 11 is provided on the rear end of the left extended bottom plate, and the left and right sides of the first partition plate 11 are respectively connected to the first curved partition plate and the left side wall 605 of the box body; a second partition plate 12 is provided on the rear end of the right extended bottom plate, and the left and right sides of the second partition plate 12 are respectively connected to the second curved partition plate 10 and the right side wall 606 of the box body.

[0062] The first partition 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 12, and the bottom plate 9 form a water inlet chamber 13. The top of the water inlet chamber 13 is open, and the side walls of the water inlet chamber 13 are open at the gap 27 between the first partition 11 and the second partition 12. The rest of the area is closed.

[0063] The water inlet pipe 601 is located on the front sidewall 604 of the housing. The first baffle 11, the first curved baffle, the first filter plate 81, the bottom plate 9, the rear sidewall of the housing 6, the second filter plate 82, the second curved baffle 10, and the second baffle 12 form a filter chamber 14. The top of the filter chamber 14 is open, while the sidewalls are open at the notch 27 between the first and second baffles 11, 12, and at the slag outlet 18 described below. The remaining areas are closed.

[0064] The water inlet chamber 13 communicates with the filter chamber 14 through a notch 27 between the first and second partitions 11, 12. The chamber within the housing 6, located outside the water inlet chamber 12 and filter chamber 13, serves as the filtered water collection chamber 15. A clean water drain pipe 17, communicating with the filtered water collection chamber 15, is provided on the sidewall of the housing 6. The number of clean water drain pipes 17 can be one or more. If there are multiple clean water drain pipes 17, each of these pipes 17 is provided with a corresponding clean water drain valve, and the outlet of each clean water drain valve is connected to the inlet of the water storage tank 900.

[0065] like Figure 12 and Figure 13 As shown, a slag outlet 18 is provided on the rear sidewall of the housing 6, communicating with the filter chamber 14. A discharge chute plate 19 is provided at the slag outlet 18 for discharging the material downwardly at an angle. The rear sidewall area of the housing 6 extending from the slag outlet 18 to the bottom plate 9 and within the filter chamber 14 is a curved sidewall 602 that is in contact with both the first filter plate 81 and the second filter plate 82.

[0066] A more optimal solution is to directly form the rear sidewall of the box body 6, from the area where the bottom plate 9 meets the rear sidewall of the box body 6, into an arcuate curved sidewall 602. A cover 20 is then hingedly connected to the upper portion of the rear sidewall of the box body 6. The cover 20 is also composed of a curved top plate 2001 and two side plates 2002. The cover 20 can be supported by a pair of hydraulic struts 21 to keep the cover 20 in an upwardly opened position during use. A handle 2003 can also be provided on the cover 20 to facilitate the operator in opening and closing the cover 20.

[0067] like Figure 11 As shown, the filter plate in this embodiment is composed of an inner fixing frame 801, a filter 802 and an outer fixing frame 803 which are stacked in sequence and connected by a number of 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 face to face.

[0068] 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 disposed between 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 connected to the first outer support ring 8002.

[0069] A more preferred solution is that the number of the first central connecting plates 8003 is preferably four, and the first central connecting plates 8003 are evenly spaced in the circumferential direction. The number of the reinforcing support plates 8014 between any two adjacent first central connecting plates 8013 is preferably two, and each reinforcing support plate 8014 evenly separates the area between any two adjacent first central connecting plates 8013.

[0070] A better solution is that the first central support ring 8011, the first outer support ring 8012, each first central connecting plate 8013, and each reinforcing support plate 8014 are integrally formed.

[0071] The outer fixing frame 803 includes a mesh 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 the second central connecting plates 8034 matches the number of the first central connecting plates 8013, and their positions also correspond one-to-one.

[0072] A more preferred option is that the second central support ring 8032, the second external support ring 8033, and the second central connecting plate 8034 are integrally formed. For the convenience of description, the plate obtained by integrally forming the second central support ring 8032, the second external support ring 8033, and the second central connecting plate 8034 is called the external connecting plate. The mesh plate 8031 is located on the inner side of the external 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 a number of fastening bolts, the mesh plate 8031 is clamped between the filter screen 802 and the external connecting plate.

[0073] In order to improve the overall strength of the filter plate, a number of external reinforcing ribs may be provided on the outer fixing frame 803 .

[0074] The first filter plate 81 is sealed with the first arc-shaped partition plate, the bottom plate 9, and the arc-shaped curved side wall 602 by a first soft sealing component; the second filter plate 82 is sealed with the second arc-shaped partition plate 10, the bottom plate 9, and the arc-shaped curved side wall 602 by a second soft sealing component.

[0075] by Figure 12 The shown orientation describes the water circulation process of the continuous filtering equipment 200 and the rinsing equipment 100. The rinsing water in the rinsing tank 1 drawn by the sludge pump 800 enters the water inlet chamber 13 of the continuous filtering equipment 200 through the drainage pipe 500 and the water inlet pipe 601, and then enters the filter chamber 14 through the gap 27 between the first partition plate 11 and the second partition plate 12. The rotating shaft 7 rotates counterclockwise under the drive of the first driving device, and relies on the friction between the inner wall of the first filter plate 81 and the second filter plate 82 and the impurities to bring the impurities to the rear of the filter chamber 14. As the rotating shaft 7 rotates, the impurities brought to the rear of the filter chamber 14 accumulate more and more. When the impurities accumulate to a certain extent, the impurities can be discharged out of 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 is then discharged into the water storage tank 900 through the clean water drainage pipes 17. The clean water in the water storage tank 900 pumped by the clean water pump 800 returns to the rinsing tank 1 through the recycling pipeline 700 to continue being used for rinsing the floating material.

[0076] During the accumulation of impurities at the rear of the filter chamber 14, since the impurities at the top of the accumulation are higher than the water level in the filter chamber 14, this part of the impurities is actually still equivalent to filtering water. Therefore, when the impurities fall into the discharge chute plate 19 through the slag outlet 18 due to the excessive accumulation height, they are very dry. These impurities are called solid waste, and dry solid waste is conducive to subsequent packaging, collection and recycling.

[0077] In addition, the continuous filtering device 200 of the above structure can continuously feed and filter, which greatly improves the filtering efficiency.

[0078] During the operation of the first filter plate 81 and the second filter plate 82, in order to prevent the filter holes on the filter screen 802 in the first filter plate 81 and the second filter plate 82 from being clogged by impurities and affecting the filtering effect, Figure 10 、 Figure 12 、 Figure 13 and Figure 14 As shown, a spray system is also provided in the box body 6; the spray system is as follows: a main spray pipe 22 is fixedly provided in the box body 6, one end of the main spray pipe 22 is connected to a water pump, and a first branch spray pipe 23 and a second branch spray pipe 24 are provided on the main spray pipe 22.

[0079] The first branch spray pipe 23 extends into the filter cavity 14 and is located at the left side of the front half of the first filter plate 81 . A plurality of first spray heads 25 spraying toward the first filter plate 81 are provided on the first branch spray pipe 23 .

[0080] The second branch spray pipe 24 extends into the filter cavity 14 and is located at the right side of the front half of the second filter plate 82 . A plurality of second spray heads 26 spraying toward the second filter plate 82 are provided on the second branch spray pipe 24 .

[0081] During the operation of the continuous filtering device 200, the rotating shaft 7 Figure 12 As shown, the counterclockwise rotation is used to move the impurities to the rear of the filter chamber 14 in the area where the first filter plate 81 and the second filter plate 82 are located at the bottom by relying on the friction between the inner wall and the impurities, while the impurities attached to the first filter plate 81 and the second filter plate 82 in the area where the first filter plate 81 and the second filter plate 82 are located at the spray system are washed away by the first spray heads 25 and the second spray heads 26 to ensure that the filter holes on the first filter plate 81 and the second filter plate 82 are always unobstructed, thereby greatly improving the water filtering effect of the continuous filtration equipment.

[0082] Example 3 This embodiment designs the rinsing device 100 based on the first embodiment to further improve the rinsing effect and make the floating material rinsed more cleanly and thoroughly.

[0083] like Figure 6 and Figure 7 As shown, the rinsing tank 1 in the rinsing apparatus 100 of this embodiment is a rectangular box-shaped structure. The feeding device 2 is a feeding screw conveyor. The discharge end 201 of the feeding screw conveyor sealably passes through a mounting hole in the rear side wall of the rinsing tank 1 and extends into the rinsing tank 1. The discharge end 201 is located at the rear lower section of the rinsing tank 2.

[0084] A more preferred solution is to arrange the screw conveyor in an inclined configuration. Specifically, the feed screw conveyor is inclined from the feed end 202 toward the discharge end 201, with the discharge end 201 being lower than the feed end 202. The feed screw conveyor has an inclination angle α relative to the horizontal plane of 30 to 40°, with the optimal inclination angle being between 32 and 35°. The feed screw conveyor is used to press the floating material obliquely into the bottom of the rear portion of the rinsing tank 1.

[0085] A more preferred solution is to adjust the position of the feed screw conveyor so that the axis of the conveying screw in the feed screw conveyor and the center plane between the left and right sides of the rinsing tank 1 are in the same plane.

[0086] In addition, in order to increase resistance to the floating material, this solution also provides a number of partitions 103 in the rinsing tank 1 to slow down the speed of the floating material reaching the floating material output end, so that the floating material has sufficient time to contact the rinsing water, thereby improving the rinsing effect.

[0087] The conveying device in the rinsing equipment 100 described in this embodiment uses a discharge dial wheel 3 and a plurality of conveying dial rods 4 to convey the floating material from the back to the front.

[0088] like Figure 2 and Figure 3 As shown, the conveying device described in this embodiment includes: a discharge dial wheel 3 and a plurality of conveying dial rods 4.

[0089] Among them, the discharge thumbwheel 3 is fixed on the axle, and the axle is supported on the rinsing tank 1 through the axle support bearing group 301 and is located on the rear side of the floating material output end; the axle is driven to rotate by the second driving device; the second driving device can adopt a second reduction motor 302.

[0090] A plurality of discharge plates 303 are provided on the circumferential wall of the discharge thumbwheel 3 for displacing the floating material at the discharge thumbwheel 3 to the floating material output end. The discharge thumbwheel 303 adopts a mesh plate structure. The mesh plate structure is adopted to minimize the amount of water carried by the floating material when the floating material is output. The two main purposes of reducing the amount of water carried by the floating material are: one is to improve the subsequent dehydration efficiency of the floating material, and the other is to reduce the amount of rinsing water in the rinsing pool 1, thereby saving water and improving water utilization.

[0091] A more preferred solution is to design the distribution of each discharge paddle plate 303 as follows: divide the said discharge paddle plates 303 into two groups, one group is the left discharge paddle plate group, and the other group is the right discharge paddle plate group; for the convenience of description, each discharge paddle plate in the left discharge paddle plate group is defined as a left discharge paddle plate 3031, and each discharge paddle plate in the right discharge paddle plate group is positioned as a right discharge paddle plate 3032.

[0092] like Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, each left-side discharging plate 3031 in the left-side discharging plate group is located on the left half of the circumferential wall of the discharging wheel 3, and each left-side discharging plate 3031 in the left-side discharging plate group is evenly spaced in sequence along the circumference of the discharging wheel 3.

[0093] Each right discharging paddle plate 3032 in the right discharging paddle plate group is located on the right half of the circumferential wall of the discharging paddle wheel 3, and each right discharging paddle plate 3032 in the right discharging paddle plate group is evenly spaced in sequence along the circumference of the discharging paddle wheel 3.

[0094] A more preferred solution is to arrange the left discharging plates 3031 in the left discharging plate group and the right discharging plates 3032 in the right discharging plate group in an alternating sequence, and to make the length of each discharging plate 303 greater than half the length of the discharging wheel 3. At this time, part of the right discharging plate 3032 will extend into the right end of the gap between each adjacent left discharging plate 3031, and part of the left discharging plate 3031 will also extend into the left end of the gap between each adjacent right discharging plate 3032.

[0095] A more preferred solution is that the left discharge paddles 3031 located on the adjacent left and right sides of each right discharge paddle 3032 are symmetrically distributed relative to the right discharge paddle 3032 .

[0096] In addition, in order to improve the connection strength between each discharge plate 303 and the discharge wheel 3, as shown in FIG. Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown, in this embodiment, a plurality of first reinforcing ribs 304 are provided between each discharge plate 303 and the circumferential wall of the discharge wheel 3. The first reinforcing ribs 304 can be triangular in shape. The optimal solution is to arrange the first reinforcing ribs 12 evenly spaced along the left-right direction of the corresponding discharge plate 9.

[0097] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7 As shown, each conveying lever 4 is supported on the rinsing tank 1 by its corresponding lever support bearing group 401, and is evenly spaced from the rear side of the discharge wheel 3 to the rear side wall of the rinsing tank 1; each conveying lever 4 is driven by its corresponding third drive device; the third drive device can adopt a third reduction motor 402.

[0098] Among them, a plurality of conveying plates 403 for conveying the material located at the corresponding conveying rod 4 forward are provided on the circumferential wall of the conveying rod 4. When each conveying rod 4 rotates, each conveying plate 403 beats and conveys the floating material forward.

[0099] like Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8 As shown, in this embodiment, the conveying plates 403 are arranged in sequence and evenly spaced along the circumference of the corresponding conveying rod 4. The conveying plates 403 include: an inner partition plate 4031 connected to the circumferential wall of the corresponding conveying rod 4, a middle partition plate 4032 inclined relative to the inner partition plate 4031, and an outer partition plate 4033 inclined relative to the middle partition plate 4032. The inclination direction of the middle partition plate 4032 and the outer partition plate 4033 are opposite to the rotation direction of the corresponding conveying rod 4, and the inner partition plate 4031, the middle partition plate 4032, and the outer partition plate 4033 are integrally formed.

[0100] The arrangement of the structure of each conveying paddle 403 enables each conveying paddle 403 to not only convey the floating material forward but also beat the floating material during the rotation of the conveying lever 4, so that the rinsing water forms undulating waves, which can scrub the floating material, thereby making the floating material cleaner and more thorough.

[0101] In addition, in order to improve the connection strength between each delivery plate 403 and the corresponding delivery rod 4, as shown in FIG. Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8 As shown, in this embodiment, a plurality of second reinforcing ribs 404 are provided between each conveying plate 403 and the circumferential wall of the corresponding conveying lever 4. The second reinforcing ribs 17 can be triangular in shape. The optimal solution is to arrange the second reinforcing ribs 404 evenly spaced along the left-right direction of the corresponding conveying plate 13.

[0102] like Figure 6 、 Figure 7 and Figure 9 As shown, in this embodiment, a plurality of slag discharge hoppers 102 are provided at the bottom of the rinsing tank 1. A slag discharge valve is installed at the slag discharge port at the bottom of each slag discharge hopper 102. The number of slag discharge hoppers 102 is determined by the size of the rinsing tank 1. When there are two or more slag discharge hoppers 102, the slag discharge hoppers 102 are generally arranged from left to right. Sediment that settles during the rinsing process is deposited in the slag discharge hoppers 102.

[0103] like Figure 2 and Figure 9As shown, in this embodiment, a discharge screw conveyor 5 is provided on the front side of the rinsing tank 2, and the feed port 501 of the discharge screw conveyor 5 is located on the top right side of the discharge screw conveyor 5, and the feed port 501 of the discharge screw conveyor 501 can receive the floating material output from the floating material output end.

[0104] The discharge port 502 of the discharge screw conveyor 501 is located on the left side of the bottom of the discharge screw conveyor 5. The discharge screw conveyor 5 is inclined from the feed port 501 toward 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 feed port 501. Several drain outlets are provided on the right side of the bottom of the discharge screw conveyor 5, each of which is equipped with a water filter. When the discharge screw conveyor 5 is in operation, the floating material in the discharge screw conveyor 5 is conveyed toward the discharge port 502 by the screw of the discharge screw conveyor 5. Rinse water entrained in the floating material flows downward and is ultimately discharged from the drain outlets, further reducing the water content in the floating material.

[0105] The water discharged from each drainage outlet can also be recycled, so that each drainage outlet is connected to the rinsing tank 1 or the drainage pipeline 500 through a circulation pipeline.

[0106] The rinsing apparatus 100 employs a forced pressing feeding method, whereby the floating material is forced into the rinsing water of the rinsing tank 1 by a feeding screw conveyor. The floating material pressed into the bottom of the rinsing tank 1 disperses and floats upward due to the inclined forced pressing action and its own characteristics. During the dispersion and floating process, the floating material is able to spread out and fully contact the rinsing water. As a result, impurities such as stains dissolved by the detergent, residual silt, and powder adhering to the floating material are easily separated from the floating material, greatly improving the rinsing effect. The floating material floating in the rinsing water is sequentially flapped and conveyed from back to front by each conveying paddle 403. During the flapping and conveying process, each conveying paddle 403 forms undulating waves in the rinsing water, which scrub the floating material, further improving the rinsing effect and making the rinsing more thorough.

[0107] In this embodiment, at least one slag discharge hopper 102 is provided at the bottom of the rinsing tank 1, and a slag discharge port is provided on each slag discharge hopper 102; the above-mentioned rinsing water discharge port 104 can be provided on the slag discharge hopper 102. When the number of slag discharge hoppers 102 is greater than or equal to 2, each slag discharge hopper 102 has a corresponding rinsing water discharge port 104, and each rinsing water discharge port 104 is connected to the drainage pipe 500 through a branch pipe.

[0108] This system also adds a vibrating screen 300, such as Figure 1The vibrating screen 300 is an existing device that can be purchased directly. Here, the vibrating screen 300 is used instead of being structurally designed. Therefore, the structure of the vibrating screen 300 will not be described in detail.

[0109] A slag screw conveyor 400 is provided at the slag outlet of each slag hopper 102. Each slag outlet corresponds to a slag screw conveyor 400, or all slag outlets are connected to the slag feed port of the same slag screw conveyor 400. The screen 3001 of the vibrating screen 300 receives the sediment discharged from the slag discharge port of the slag screw conveyor 400. The vibrating screen 300 separates the sediment into solids and liquids, removing excess moisture from the sediment. A sediment collection box 3002 can also be provided at the sediment outlet of the vibrating screen 300.

[0110] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any modification or equivalent change made according to the technical essence of the present invention shall still fall within the scope of protection required by the present invention.
