AI Technical Summary
In existing rinsing devices, the floating material has strong encapsulation and buoyancy during the rinsing process, which causes some stains and impurities to not fully contact the rinsing water. This is especially true when the input volume is high, which can easily lead to incomplete separation of impurities.
The design employs a forced material pressing system, where a feeding screw conveyor forces floating material into the rinsing water. Combined with the inclined angle and baffle structure, the floating material is dispersed and spread out in the rinsing water. The rinsing effect is improved by the patting action of the conveyor plates and the washing action of the water waves.
It effectively improves the rinsing effect, making it easier to remove stains and impurities adhering to the floating material, resulting in a cleaner and more thorough rinsing. The floating material also has more sufficient contact with water, reducing the water content in the subsequent dehydration process.

Abstract
Description
Technical Field
[0001] This utility model relates to a rinsing device in a waste plastic floating material recycling production line, and more particularly to a forced pressing type rinsing device. Background Technology
[0002] The waste plastic floating material recycling production line is mainly for crushing, cleaning, regenerating and recycling floating materials such as industrial film, agricultural film, garbage film, PP woven bags, and ton bags. The main supporting equipment includes crushing device, washing device, dewatering device, rinsing device, squeezing device, and drying device.
[0003] The rinsing device is one of the essential pieces of equipment in the production line for recycling and reusing waste plastic floating materials. After being cleaned by the cleaning device, the floating materials are covered with stains, residual mud, powder and other impurities dissolved by the cleaning agent. By rinsing the cleaned floating materials with the rinsing device, the floating materials can be made cleaner, and the purity and processing performance of the recycled floating materials can be improved.
[0004] Currently, common rinsing devices on the market include: a rinsing tank, where floating material is manually or fed into the floating material input area of the rinsing tank from above, and a conveying device in the rinsing tank to transport the floating material to the floating material output end of the rinsing tank. The conveying device includes: several conveying levers, and several teeth are provided on the circumferential wall of each conveying lever. When each conveying lever rotates, it moves the floating material to the floating material output end of the rinsing tank through the teeth.
[0005] However, due to the strong encapsulation of the float and its own buoyancy, some of the float in the float input area cannot fully expand and come into full contact with the rinsing water in the rinsing tank to wash away all the stains dissolved by the cleaning agent, residual mud, powder and other impurities adhering to the float. Especially when a large amount of float is put in, some sludge and other impurities may be lifted by the float and cannot be separated from it, resulting in a less than ideal rinsing effect. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a forced-press rinsing device that is compact in structure, easy to operate, and has a good rinsing effect.
[0007] To address the inherent characteristics of floating materials and the poor rinsing performance of common rinsing devices, this invention employs a forced-pressing method. The floating material is forcibly pressed into the rinsing water. Under the influence of its own properties and the forced pressing, the material disperses and rises. During this dispersion and rising process, the material expands and fully contacts the rinsing water. Consequently, impurities such as stains dissolved by the cleaning agent, residual mud, and powder adhering to the material are easily removed, improving the rinsing effect. Furthermore, the conveyor plates beat and transport the material forward, creating undulating waves in the rinsing water. These waves effectively scrub the material, further enhancing the rinsing effect and resulting in a cleaner, more thorough rinse.
[0008] The technical solution adopted by this utility model is as follows: the forced pressure rinsing device includes: a rinsing tank, on which a rinsing water inlet is provided, through which rinsing water enters the rinsing tank; a water inlet pipe can be provided at the rinsing water inlet, and a water pump is provided on the water inlet pipe. When the water inlet pipe is connected to a rinsing water source, clean rinsing water can be injected into the rinsing tank through the water pump.
[0009] The rinsing tank is equipped with a rinsing water outlet, through which the rinsing water in the rinsing tank is discharged outside the rinsing tank. Alternatively, a drainage pipe can be installed at the rinsing water outlet, with a drainage pump installed on the drainage pipe to pump out the rinsing water from the rinsing tank. Or, a drainage pump can be omitted from the drainage pipe, and the rinsing water outlet can be positioned at a low level, allowing the rinsing water to be discharged by opening the rinsing water outlet.
[0010] The rinsing tank has a rectangular box structure; a feeding device is provided on the rear side of the rinsing tank to force the floating material into the rinsing water of the rinsing tank, and the discharge end of the feeding device is located in the lower rear section of the rinsing tank; the top front side of the rinsing tank is the floating material output end, and a conveying device is provided in the rinsing tank to transport the floating material to the floating material output end.
[0011] Furthermore, in the aforementioned forced-feed rinsing device, the feeding device is a feeding screw conveyor. The discharge end of the feeding screw conveyor extends into the rinsing tank after passing through a mounting hole on the rear side wall of the rinsing tank. The feeding screw conveyor is inclined from the feed end to the discharge end, and the height of the discharge end of the feeding screw conveyor is lower than the height of the feed end. After the required amount of rinsing water is injected into the rinsing tank, the floating material is forced into the rinsing water by the inclined forced-feed method. The inclined forced-feed method can better help the floating material disperse, spread, and float in the rinsing tank, improving the separation effect of the floating material from the stains dissolved by the cleaning agent, residual mud, powder, and other impurities.
[0012] Furthermore, in the aforementioned forced-feed rinsing device, the axis of the conveying screw in the feed screw conveyor is on the same plane as the center plane between the left and right sides of the rinsing tank; the inclination angle of the feed screw conveyor relative to the horizontal plane is 30-40°.
[0013] To increase resistance to the floating material, this design also includes several baffles in the rinsing tank to slow down the speed at which the floating material reaches the output end, thus allowing the floating material sufficient time to contact the rinsing water and improving the rinsing effect.
[0014] Furthermore, in the aforementioned forced-press rinsing device, the conveying device includes: a discharge wheel and several conveying levers;
[0015] The discharge wheel is fixed on the axle, which is supported on the rinsing tank by the axle support bearing assembly and is located behind the floating material output end. The axle is driven to rotate by the first drive device. Several discharge plates are provided on the circumferential wall of the discharge wheel to push the floating material at the discharge wheel towards the floating material output end. The discharge plates are perforated plates. The perforated plate structure is set to minimize the water content of the floating material during output. The two main purposes of reducing the water content of the floating material are to improve the subsequent dewatering efficiency and to reduce the amount of rinsing water in the rinsing tank.
[0016] Each conveying lever is supported on the rinsing tank by its corresponding lever support bearing assembly, and is evenly spaced from the rear side of the discharge lever toward the rear wall of the rinsing tank; each conveying lever is driven by its corresponding second drive device; several conveying plates are provided on the circumferential wall of the conveying lever to convey the floating material located at the corresponding conveying lever forward.
[0017] Furthermore, in the aforementioned forced-pressure rinsing device, each discharge baffle is divided into two groups: a left discharge baffle group and a right discharge baffle group; at this time, the number of discharge baffles in the left discharge baffle group is the same as the number of discharge baffles in the right discharge baffle group.
[0018] Each discharge plate in the left discharge plate group is located on the circumferential wall of the left half of the discharge wheel, and each discharge plate in the left discharge plate group is arranged sequentially and evenly at intervals along the circumference of the discharge wheel.
[0019] Each discharge plate in the right discharge plate group is located on the right half of the circumferential wall of the discharge wheel, and each discharge plate in the right discharge plate group is arranged in a sequential and evenly spaced manner along the circumference of the discharge wheel.
[0020] The discharge plates in the left discharge plate group and the discharge plates in the right discharge plate group are arranged alternately in sequence, and the length of each discharge plate is greater than half the length of the discharge wheel.
[0021] Furthermore, in the aforementioned forced-pressure rinsing device, a plurality of first reinforcing ribs are provided between the circumferential wall of each discharge deflector and the discharge wheel to enhance the stability of the connection between the discharge deflectors. A more preferred embodiment is that each of the first reinforcing ribs is located on the first non-conveying surface of the corresponding discharge deflector.
[0022] Furthermore, in the aforementioned forced-press rinsing device, each conveying plate is arranged sequentially and evenly at intervals along the circumference of the corresponding conveying rod.
[0023] The conveying baffle comprises: an inner baffle connected to the circumferential wall of the corresponding conveying lever, a middle baffle inclined relative to the inner baffle, and an outer baffle inclined relative to the middle baffle. The inclination directions of the middle baffle and the outer baffle are opposite to the rotation direction of the corresponding conveying lever during forward conveying. The inner baffle, middle baffle, and outer baffle are integrally formed. The inner baffle, middle baffle, and outer baffle can be obtained by bending a single piece of plate, with the bends using a rounded transition.
[0024] Furthermore, in the aforementioned forced-pressure rinsing device, a plurality of second reinforcing ribs are provided between the circumferential wall of each conveying plate and the corresponding conveying lever to enhance the stability of the connection between each conveying plate. A more preferred embodiment is that each of the second reinforcing ribs is located on the second non-conveying surface of the corresponding conveying plate.
[0025] Furthermore, in the aforementioned forced-press rinsing device, several slag discharge hoppers are provided at the bottom of the rinsing tank, and a slag discharge port can be provided at the bottom of each slag discharge hopper. When the slag discharge port is not discharging slag, it is in a closed state. During the rinsing process, the sediment that sinks accumulates in the slag discharge hopper, and when discharging slag, the sediment is discharged out of the slag discharge hopper through the slag discharge port.
[0026] A better solution is to set the rinsing water outlet on the slag hopper. When the number of slag hoppers is greater than or equal to 2, each slag hopper has a corresponding rinsing water outlet.
[0027] Furthermore, in the aforementioned forced-press rinsing device, a discharge screw conveyor is provided on the front side of the rinsing tank. The inlet of the discharge screw conveyor is located on the top right side of the discharge screw conveyor, and the inlet of the discharge screw conveyor can receive the floating material output from the floating material output end.
[0028] The discharge port of the discharge screw conveyor is located on the bottom left side of the discharge screw conveyor. The discharge screw conveyor is inclined from the inlet to the outlet, and the height of the discharge port is higher than the height of the inlet.
[0029] Several drainage outlets are located on the bottom right side of the discharge screw conveyor, each equipped with a filter screen. These outlets further reduce the water content in the floating material. The inclined discharge screw conveyor facilitates the further separation of rinsing water and floating material, further reducing the water content in the floating material and improving the subsequent dewatering efficiency.
[0030] The beneficial effects of this invention are as follows: The above-mentioned forced-feed rinsing device uses a forced-feed method to force the floating material into the rinsing water. At this time, the floating material disperses, unfolds, and floats upward under its own characteristics and the forceful pressure. During the process of dispersion, unfolding, and floating, the floating material can fully contact the rinsing water. Therefore, the stains dissolved by the cleaning agent, residual mud, powder, and other impurities adhering to the floating material are easily removed, greatly improving the rinsing effect. In addition, the floating material is patted and conveyed forward by each conveyor plate. During the patting and forward conveying process, the rinsing water forms undulating waves. These undulating waves can rub and wash the floating material, further improving the rinsing effect and making the rinsing cleaner and more thorough. Attached Figure Description

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0043] The forced-pressure rinsing device described in this embodiment, such as Figure 1As shown, the system includes a rinsing tank 2, which is typically mounted on a frame 1. A rinsing water inlet is provided on the rinsing tank 1, through which rinsing water is injected into the rinsing tank 1. A level gauge or level sensor can also be installed in the rinsing tank 1 to monitor the level of the rinsing water in real time. A valve, drain pump, etc., can be installed on the drain pipe connected to the rinsing water inlet. The level sensor can transmit signals to a control device, which in turn can communicate with the valve and drain pump controlling the rinsing water injection, and replenish rinsing water as needed to ensure the rinsing water level in the rinsing tank 1 meets usage requirements. A rinsing water outlet is also provided on the rinsing tank 1, through which the rinsing water in the rinsing tank 1 is discharged outside the rinsing tank 1. A drain valve can also be installed at the rinsing water outlet, and this drain valve can also communicate with the control device to achieve automatic control.
[0044] like Figure 1 and Figure 6 As shown, the rinsing tank 2 in this embodiment has a rectangular box structure. A feeding device 3 is installed on the rear side of the rinsing tank 2 to force floating material into the rinsing water. The discharge end 4 of the feeding device 3 is located in the lower rear section of the rinsing tank 2. The top front side of the rinsing tank 2 is the floating material output end, and a conveying device is installed in the rinsing tank 2 to transport the floating material to the floating material output end.
[0045] like Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the feeding device 3 is a feeding screw conveyor. The discharge end 4 of the feeding screw conveyor passes through the mounting hole on the rear side wall of the rinsing tank 1 and extends into the rinsing tank 2. The feeding screw conveyor is inclined from the feeding end 5 to the discharge end 4, and the height of the discharge end 4 of the feeding screw conveyor is lower than the height of the feeding end 5.
[0046] 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 is on the same plane as the center plane between the left and right sides of the rinsing tank 2.
[0047] A more preferred embodiment is that the inclination angle α of the feed screw conveyor relative to the horizontal plane is 30 to 40°, with the optimal inclination angle being between 32 and 35°.
[0048] In addition, to increase the resistance of the floating material, this scheme also sets up several baffles 24 in the rinsing tank 2 to slow down the speed at which the floating material reaches the floating material output end, so that the floating material has enough time to contact the rinsing water and improve the rinsing effect.
[0049] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the conveying device in this embodiment includes: a discharge wheel 6 and several conveying levers 7.
[0050] like Figure 1 and Figure 2 As shown, the discharge wheel 6 is fixed on the axle, and the axle is supported on the rinsing tank 2 by the axle support bearing group 8 and is located on the rear side of the floating material output end. The axle of the discharge wheel 6 is driven to rotate by the first drive device, which can be a first reduction motor 22.
[0051] On the circumferential wall of the discharge wheel 6, there are several discharge plates 9 that push the floating material located at the discharge wheel 6 toward the floating material output end. The discharge plates 9 are perforated plates. The purpose of setting the perforated plate structure is to minimize the amount of water carried by the floating material during the output. The two main purposes of reducing the amount of water carried by the floating material are to improve the subsequent dewatering efficiency of the floating material and to reduce the amount of rinsing water in the rinsing tank.
[0052] A more preferred approach is to design the distribution of each discharge baffle 9 as follows: each discharge baffle 9 is divided into two groups, one group being the left discharge baffle group and the other group being the right discharge baffle group; for ease of description, each discharge baffle in the left discharge baffle group is defined as the left discharge baffle 10, and each discharge baffle in the right discharge baffle group is positioned as the right discharge baffle 11.
[0053] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, each left discharge deflector 10 in the left discharge deflector group is located on the left half of the circumferential wall of the discharge deflector wheel 6, and each left discharge deflector 10 in the left discharge deflector group is arranged sequentially and evenly at intervals along the circumference of the discharge deflector wheel 6.
[0054] Each right-side discharge deflector 11 in the right-side discharge deflector group is located on the right half of the circumferential wall of the discharge deflector wheel 6, and each right-side discharge deflector 11 in the right-side discharge deflector group is arranged sequentially and evenly at intervals along the circumference of the discharge deflector wheel 6.
[0055] A more preferred embodiment is to arrange the left discharge deflectors 10 in the left discharge deflector group and the right discharge deflectors 11 in the right discharge deflector group in a staggered manner, and to make the length of each discharge deflector 9 greater than half the length of the discharge wheel 6. In this case, a portion of the right discharge deflector 11 will extend into the right end of the gap between two adjacent left discharge deflectors 10, and a portion of the left discharge deflector 10 will also extend into the left end of the gap between two adjacent right discharge deflectors 11.
[0056] A more preferred embodiment is that the left discharge plates 10 located on the adjacent left and right sides of each right discharge plate 11 are symmetrically distributed relative to the right discharge plate 11.
[0057] In addition, to improve the connection strength between each discharge plate 9 and the discharge wheel 6, such as Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, in this embodiment, a plurality of first reinforcing ribs 12 are provided between the circumferential wall of each discharge plate 9 and the discharge wheel 6. The first reinforcing ribs 12 can be triangular reinforcing rib structures.
[0058] A better solution is to arrange each of the first reinforcing ribs 12 at even intervals along the left and right directions of the corresponding discharge baffle 9.
[0059] A better solution is to position each of the first reinforcing ribs 12 on the first non-conveying surface 25 of the corresponding discharge baffle plate 11.
[0060] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in this embodiment, each conveying lever 7 is supported on the rinsing tank 2 by its corresponding lever support bearing assembly, and is evenly spaced from the rear side of the discharge lever 6 towards the rear wall of the rinsing tank 2; each conveying lever 7 is driven by its corresponding second drive device, which can be a second reduction motor 23. Several conveying plates 13 are provided on the circumferential wall of each conveying lever 7 to convey the floating material located at the corresponding conveying lever 7 forward.
[0061] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in this embodiment, each conveying plate 13 is arranged sequentially and evenly at intervals along the circumference of the corresponding conveying rod 7. The conveying plate 13 comprises: an inner partition 14 connected to the circumferential wall of the corresponding conveying rod 7, a middle partition 15 inclined relative to the inner partition 14, and an outer partition 16 inclined relative to the middle partition 15. The inclination directions of the middle partition 15 and the outer partition 16 are opposite to the rotation direction of the corresponding conveying rod 7 during the forward conveying of floating material, and the inner partition 14, the middle partition 15, and the outer partition 16 are integrally formed.
[0062] The structure of each conveyor plate 13 allows each conveyor lever 7 to both convey the floating material forward and beat it during rotation, creating undulating waves in the rinsing water. These undulating waves effectively scrub the floating material, making it cleaner and more thorough.
[0063] In addition, to improve the connection strength between each conveyor plate 13 and the corresponding conveyor lever 7, such as Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment, a plurality of second reinforcing ribs 17 are provided between the circumferential wall of each conveying plate 13 and the corresponding conveying lever 7. The second reinforcing ribs 17 can be triangular reinforcing rib structures.
[0064] A better solution is to arrange the second reinforcing ribs 17 at even intervals along the left and right directions of the corresponding conveying plate 13.
[0065] A better solution is to position each of the second reinforcing ribs 17 on the second non-conveying surface 26 of the corresponding conveying plate 13.
[0066] like Figure 5 , Figure 6 and Figure 8 As shown, in this embodiment, several slag discharge hoppers 18 are provided at the bottom of the rinsing tank 2. Each slag discharge hopper 18 has a slag discharge port at its bottom, which is closed when no slag is being discharged. The number of slag discharge hoppers 18 is determined according to the size of the rinsing tank 2. When there are two or more slag discharge hoppers 18, they are usually arranged from left to right. During the rinsing process, the sediment settles in each slag discharge hopper 18 and can be discharged out of the slag discharge hopper 18 through each slag discharge port.
[0067] A better solution is to set the rinsing water outlet on the slag discharge hopper 18. When the number of slag discharge hoppers 18 is greater than or equal to 2, each slag discharge hopper 18 has a corresponding rinsing water outlet.
[0068] like Figure 1 and Figure 8 As shown, in this embodiment, a discharge screw conveyor 19 is provided on the front side of the rinsing tank 2. The inlet 20 of the discharge screw conveyor 19 is located on the top right side of the discharge screw conveyor 19, and the inlet 20 of the discharge screw conveyor 19 can receive the floating material output from the floating material output end.
[0069] The discharge port 21 of the discharge screw conveyor 19 is located on the bottom left side of the discharge screw conveyor 19. The discharge screw conveyor 19 is inclined from the inlet 20 to the discharge port 21, and the height of the discharge port 21 is higher than the height of the inlet 20. Several drainage ports are provided on the bottom right side of the discharge screw conveyor 19, and a filter screen is provided at each drainage port. At this time, when the discharge screw conveyor 19 is working, the floating material in the discharge screw conveyor 19 will be conveyed to the discharge port 21 by the screw in the discharge screw conveyor 19, while some of the rinsing water entrained in the floating material will flow downward and eventually be discharged from each drainage port. This part can further reduce the water content in the floating material.
[0070] The aforementioned forced-feed rinsing device uses a forced-feed method. A screw conveyor forces the floating material into the rinsing water of the rinsing tank 2. The floating material, pressed to the bottom of the rinsing tank 2, disperses and floats upwards under the force of the inclined forcing action and its own inherent properties. The baffles 24 slow down the forward transport speed of the floating material. During this dispersion and upward movement, the floating material can fully contact the rinsing water, thus easily removing stains dissolved by the cleaning agent, residual mud, powder, and other impurities, greatly improving the rinsing effect. The floating material in the rinsing water is then sequentially patted and conveyed from back to front by various conveyor plates. During this patting and conveying process, the rinsing water forms undulating waves, which effectively scrub the floating material, further improving the rinsing effect and resulting in a cleaner and more thorough rinse. Finally, as the discharge wheel 6 rotates, the floating material is pushed towards the output end by each discharge plate 9 and falls into the inlet 20 of the discharge screw conveyor 19, and is then transported to the next station by the discharge screw conveyor 19.
[0071] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
