Description

Technical Field

[0001] This invention relates to the field of starch production technology, and in particular to a starch preparation device with an automatic rinsing function. Background Technology

[0002] Corn starch is a high-molecular-weight carbohydrate, a polysaccharide composed of single-type sugar units. Currently, the raw material for corn starch is usually dried corn kernels, which are processed through washing, crushing, sieving, sedimentation, drying, and grinding. Existing methods for removing corn kernels primarily involve high-pressure water washing and soaking to remove light impurities such as corn silk and stalks, as well as sedimentary impurities like sand and mud. Since these light impurities are generally less dense than water, they float on the surface. Current corn kernel washing and impurity removal equipment with scum removal capabilities raises the liquid level to submerge the scum interception structure, then lowers the liquid level to guide the scum into the interception structure. During this process, sufficient gaps must be maintained between the scum interception structure and the water storage structure to allow the scum to float normally above the interception mechanism. However, as the scum descends with the liquid level, a small portion still falls through the gaps between the interception structure and the water storage structure to the surface of the water in the storage structure. Summary of the Invention

[0003] Therefore, it is necessary to provide a starch preparation device with an automatic rinsing function to address the problem that the starch preparation device with automatic rinsing function has poor cleaning effect on scum.

[0004] A starch preparation device with automatic rinsing function, comprising:

[0005] The system includes a bubble cleaner, a screw feeder, a first mesh belt conveyor, a second mesh belt conveyor, a storage bin, and a high-pressure water cleaner. The screw feeder is installed at one end of the bubble cleaner. Both the first and second mesh belt conveyors are installed inside the bubble cleaner. One end of the second mesh belt conveyor extends to the outside of the bubble cleaner. The storage bin is located below the second mesh belt conveyor. The high-pressure water cleaner is installed on the surface of the bubble cleaner, and its top is positioned above the bubble cleaner.

[0006] A scum removal device is fixedly connected to the top of the bubble cleaning machine.

[0007] Furthermore, the scum removal device includes an installation box, a chain conveyor, two adaptive lifting mechanisms, two hollowed-out scum removal mechanisms, and a collection net box. The installation box is fixedly connected to and communicates with the top of the bubble cleaner. The chain conveyor is fixedly connected to the surface of the installation box, with one end of the chain conveyor penetrating into the interior of the installation box. The top of the high-pressure water cleaner penetrates the installation box and extends to the inner side of the chain conveyor. Both adaptive lifting mechanisms are fixedly connected to the surface of the chain conveyor and are respectively located on the upper and lower sides of the top of the high-pressure water cleaner. The two hollowed-out scum removal mechanisms are respectively fixedly connected to the surfaces of the two adaptive lifting mechanisms. The width of the hollowed-out scum removal mechanism is the same as the width of the installation box. The collection net box is inserted into the surface of the installation box. One end of the collection net box penetrates the installation box and the chain conveyor in sequence and extends directly below the hollowed-out scum removal mechanism above. The collection net box is located at the end of the high-pressure water cleaner facing away from the screw feeder.

[0008] In one embodiment, the chain conveyor and the perforated scum removal mechanism work together to circulate and filter out the scum floating on the water surface. This can cover the entire water surface of the bubble cleaner to improve the scum removal rate and thus improve the cleaning effect on the water surface.

[0009] Furthermore, the adaptive lifting mechanism includes a cylinder, a lifting plate, an anti-detachment plate, and a float. The cylinder is fixedly connected to the inner side of the chain conveyor. The lifting plate is fixedly connected to the surface of the cylinder facing away from the top of the high-pressure water cleaner. The anti-detachment plate is fixedly connected to one end of the lifting plate facing away from the cylinder. The float is slidably connected to the surface of the lifting plate. One end of the float is fixedly connected to the hollow slag removal mechanism. The direction of the float toward the hollow slag removal mechanism is the same as the driving direction of the chain conveyor.

[0010] In one embodiment, the adaptive lifting mechanism can drive the hollow slag removal mechanism to float on the water surface after entering the water, so as to meet the slag removal needs at different water levels.

[0011] Furthermore, both vertical inner walls of the mounting box are provided with U-shaped grooves. One end of the cylinder is connected to both U-shaped grooves. The two vertical inner walls of the U-shaped grooves are respectively located on both sides of the top of the high-pressure water cleaner. The vertical inner wall of the lower U-shaped groove is located between the lower cylinder and the top of the high-pressure water cleaner. The adaptive lifting mechanism also includes piston rods, springs, elastic air bladders, two push plates, and two positioning blocks. The lifting plate has an internal mounting cavity. Both vertical inner walls of the float block have evenly distributed positioning grooves. The mounting cavity is connected to the positioning grooves. The two piston rods... Both piston rods are slidably connected inside the cylinder barrel. One end of the piston rod opposite the U-shaped groove passes through the cylinder barrel and the U-shaped groove and contacts the U-shaped groove. The spring is disposed between the two piston rods and inside the cylinder barrel. The elastic airbag is disposed inside the mounting cavity. One end of the elastic airbag is connected to the cylinder barrel. The connection between the elastic airbag and the cylinder barrel is always disposed between the two piston rods. The push plate is slidably connected inside the mounting cavity. The two push plates are symmetrically fixedly connected to both ends of the elastic airbag. The two positioning blocks are respectively fixedly connected to the opposite ends of the two push plates. The positioning blocks are aligned with the adjacent positioning grooves.

[0012] In one embodiment, the hollow slag removal mechanism is automatically locked by air pressure before passing through the high-pressure water spray area, so that the hollow slag removal mechanism can stably pass through the high-pressure water spray area.

[0013] Furthermore, the scum cleaning device also includes a pressing strip, which is fixedly connected to the inner top wall of the mounting box. The pressing strip is located on the side of the U-shaped trough facing away from the screw feeder. The pressing strip is also located on the inner top wall of the collection net box. The adaptive lifting mechanism also includes a pressing valve and an air guide pipe. The pressing valve is fixedly connected to one end of the anti-detachment plate facing away from the cylinder. One end of the pressing valve is in contact with the pressing strip. One end of the pressing valve is connected to the elastic airbag. The air guide pipe is fixedly connected to one end of the anti-detachment plate. One end of the air guide pipe is connected to the pressing valve. The other end of the air guide pipe faces the hollowed-out scum removal mechanism.

[0014] In one embodiment, during the slag discharge process of the hollow slag removal mechanism, air can be blown into the interior of the hollow slag removal mechanism in conjunction with the pressing strip, so that the slag discharge of the hollow slag removal mechanism is more thorough and avoids bringing the floating slag back into the water.

[0015] Furthermore, the adaptive lifting mechanism also includes uniformly distributed elastic diaphragm flaps, which are fixedly connected to the inner wall of the air duct. The elastic diaphragm flaps are fixedly connected to the inner wall of the air duct in a ring around the axis of the air duct. Adjacent elastic diaphragm flaps abut against each other, and all the elastic diaphragm flaps together form a pointed cone shape facing away from the anti-detachment plate.

[0016] In one embodiment, this can prevent external water from entering the gas duct without affecting the normal flow of gas, thereby achieving a good one-way barrier effect.

[0017] Furthermore, the adaptive lifting mechanism also includes a one-way valve, which is fixedly connected to and communicates with the surface of the cylinder barrel, and the blocking direction of the one-way valve is the same as the direction from the cylinder barrel to the one-way valve.

[0018] In one embodiment, without affecting the piston rod's normal compression of air into the elastic air bladder, this allows for rapid entry while negative pressure is generated inside the cylinder, thus ensuring pressure balance inside and outside the cylinder.

[0019] Furthermore, both vertical inner walls of the U-shaped groove are inclined toward the direction of the screw feeder, and the adaptive lifting mechanism also includes two ball bearings, which are rotatably connected to the opposite ends of the two piston rods.

[0020] In one embodiment, this allows the piston rod to enter the U-groove more smoothly, reducing the probability of the piston rod getting stuck inside the U-groove.

[0021] Furthermore, the hollowed-out slag removal mechanism includes an arc-shaped net box, a round shaft, an L-shaped mesh plate, a spring, and an anti-detachment strip. The arc-shaped net box is fixedly connected to one end of the float, with the opening of the arc-shaped net box facing away from the float. The round shaft is rotatably connected to the inside of the arc-shaped net box, and the L-shaped mesh plate is rotatably connected to the surface of the round shaft. The spring is fixedly connected between the round shaft and the L-shaped mesh plate, and the anti-detachment strip is fixedly connected to the inner wall of the arc-shaped net box. One end of the anti-detachment strip is in contact with the L-shaped mesh plate, and the spring always applies a pushing force towards the anti-detachment strip to the L-shaped mesh plate.

[0022] In one embodiment, this can remove floating scum by scooping, and after the arc-shaped net box pulls the scum out of the water, it can also drain the water from the scum, thereby improving the drying efficiency of the collected scum.

[0023] Furthermore, the scum cleaning device also includes a rack, which is fixedly connected to the inner top wall of the mounting box. The rack is not only positioned between the pressing bar and the U-shaped groove, but also between the end of the pressing bar facing away from the screw feeder and the end of the pressing bar facing the screw feeder. One end of the L-shaped mesh plate above contacts the rack, and the rack is positioned directly above the collecting mesh box.

[0024] In one embodiment, the rack is used in conjunction with the perforated slag-removing mechanism. This not only lowers the perforated slag-removing mechanism to its lowest height, reducing the impact of slag on the collection net box and the probability of slag jumping out of the collection net box due to the impact, but also allows the rack and spring to drive the L-shaped mesh plate to vibrate and rotate back and forth, improving the slag removal effect inside the arc-shaped net box and the L-shaped mesh plate itself, thereby improving the effective collection rate of slag.

[0025] Furthermore, the scum cleaning device also includes a guide bucket, which is fixedly connected to the inside of the mounting box, and the lower opening of the guide bucket is connected to the collection net box.

[0026] In one embodiment, the guide bucket can not only guide scum falling over a larger area into the collection cage, but also increase the height at which the scum jumps out of the collection cage, thereby avoiding the probability of the scum falling back into the water.

[0027] 1. The starch preparation device with automatic rinsing function described above, in combination with the chain conveyor and the hollow slag removal mechanism, can circulate and filter out the scum floating on the water surface. This can cover the entire water surface of the bubble cleaner, solving the problem that the existing starch preparation devices with scum removal function have poor scum removal effect. Furthermore, the hollow slag removal mechanism, the adaptive lifting mechanism and the rack and pinion can stably float on the water surface when removing scum, and can also discharge the scum into the collection net box more thoroughly when discharging scum, avoiding the scum from flowing back, thereby improving the cleaning effect of the scum on the water surface.

[0028] 2. The adaptive lifting mechanism can drive the hollow slag removal mechanism to float on the water surface after entering the water to meet the slag removal needs at different water levels. Before the hollow slag removal mechanism passes through the high-pressure water spray area, it can lock the hollow slag removal mechanism by air pressure, so that the hollow slag removal mechanism can pass through the high-pressure water spray area stably. During the slag removal process of the hollow slag removal mechanism, it can work with the pressing strip to blow air into the hollow slag removal mechanism, so that the slag removal mechanism can remove slag more thoroughly and avoid bringing the floating slag back into the water later.

[0029] 3. The rack and pinion mechanism is used in conjunction with the perforated slag removal mechanism. This not only lowers the perforated slag removal mechanism to its lowest height, reducing the impact of slag on the collection net box and the probability of slag jumping out of the collection net box due to the impact, but also allows the rack and pinion mechanism to drive the L-shaped net plate to vibrate and rotate back and forth, improving the slag removal effect inside the arc-shaped net box and the L-shaped net plate itself, thereby improving the effective collection rate of slag.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0049] The following is combined with Figure 1 - Figure 11 The present invention describes a starch preparation apparatus with an automatic rinsing function.

[0050] In one embodiment, a starch preparation device with an automatic rinsing function includes a bubble cleaner 100, a screw feeder 200 installed at one end of the bubble cleaner 100, a first mesh belt conveyor 300 and a second mesh belt conveyor 400 installed inside the bubble cleaner 100, one end of the second mesh belt conveyor 400 extending to the outside of the bubble cleaner 100, a storage box 500 placed below the second mesh belt conveyor 400, a high-pressure water cleaner 600 installed on the surface of the bubble cleaner 100, the top of the high-pressure water cleaner 600 being positioned above the bubble cleaner 100, and a scum removal device 700 fixedly connected to the top of the bubble cleaner 100.

[0051] When workers need to rinse corn kernels, they first fill the bubble washing machine 100 with water, ensuring the water level rises to between the bottom wall of the mounting box 710 and the bottom of the chain conveyor 720. Workers then manually start the bubble washing machine 100, screw feeder 200, first mesh belt conveyor 300, second mesh belt conveyor 400, and high-pressure water washer 600. Next, the corn kernels are placed into the screw feeder 200, which conveys them into the bubble washing machine 100 and onto the first mesh belt conveyor 300. The first mesh belt conveyor 300 then horizontally... During the feeding of corn kernels, the bubble washer 100 continuously generates upward bubbles, which cause the water to churn and clean the corn kernels. At the same time, the high-pressure water washer 600 sprays high-pressure water downwards, which churns and rinses the corn kernels to improve the cleaning effect. After the first mesh belt conveyor 300 conveys the cleaned corn kernels to the surface of the second mesh belt conveyor 400, the second mesh belt conveyor 400 tilts the corn kernels upwards, causing the corn kernels to quickly leave the water surface and finally fall into the storage bin 500. The workers can then use the cleaned corn kernels in the storage bin 500 for the next crushing operation.

[0052] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the scum cleaning device 700 includes a mounting box 710, which is fixedly connected to and communicates with the top of the bubble cleaner 100. A chain conveyor 720 is fixedly connected to the surface of the mounting box 710, with one end of the chain conveyor 720 extending into the interior of the mounting box 710. The top of the high-pressure water cleaner 600 extends through the mounting box 710 and into the inner side of the chain conveyor 720. Two adaptive lifting mechanisms 730 are fixedly connected to the inner side of the chain conveyor 720. Adaptive lifting mechanisms 730 are respectively installed on the upper and lower sides of the top of the high-pressure water cleaner 600. A perforated slag-removing mechanism 740 is fixedly connected to the surface of the adaptive lifting mechanism 730. The width of the perforated slag-removing mechanism 740 is the same as the width of the mounting box 710. A collection net box 750 is inserted into the surface of the mounting box 710. One end of the collection net box 750 passes through the mounting box 710 and the chain conveyor 720 and extends directly below the perforated slag-removing mechanism 740. The collection net box 750 is positioned... The high-pressure water washer 600 faces away from the screw feeder 200. When workers need to clean the scum floating on the water surface inside the bubble washer 100, they only need to start the chain conveyor 720. The chain conveyor 720 synchronously drives all the adaptive lifting mechanisms 730 and the hollow scum removal mechanism 740 to move in a cycle. After the adaptive lifting mechanism 730 and the hollow scum removal mechanism 740 enter the water, the hollow scum removal mechanism 740 can scoop water during subsequent movement. The filtration method concentrates the floating scum inside the filter. Then, the chain conveyor 720 drives the hollow scum removal mechanism 740, which carries the scum, to leave the water surface. When the hollow scum removal mechanism 740 moves directly above the collection net box 750, the opening of the hollow scum removal mechanism 740 is exactly vertically open to the side. The scum falls into the collection net box 750 under the action of gravity, so that the scum cleaning device 700 can circulate and remove scum, and the scum removal range can cover the entire water surface of the bubble cleaning machine 100.

[0053] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the adaptive lifting mechanism 730 includes a cylinder 7301, a lifting plate 7302, an anti-detachment plate 7303, and a float 7304. The cylinder 7301 is fixedly connected to the inner side of the chain conveyor 720. The lifting plate 7302 is fixedly connected to the surface of the cylinder 7301 facing away from the top of the high-pressure water cleaner 600. The anti-detachment plate 7303 is fixedly connected to one end of the lifting plate 7302 facing away from the cylinder 7301. The float 7304 is slidably connected to the surface of the lifting plate 7302. On the surface, one end of the float 7304 is fixedly connected to the hollow slag removal mechanism 740. The direction of the float 7304 toward the hollow slag removal mechanism 740 is the same as the driving direction of the chain conveyor 720. When the adaptive lifting mechanism 730 and the hollow slag removal mechanism 740 are submerged in water, the float 7304 floats under its own characteristics, causing the hollow slag removal mechanism 740 to float on the water surface, so that the hollow slag removal mechanism 740 can more accurately remove the floating residue on the water surface.

[0054] The mounting box 710 has two vertical inner walls with U-shaped grooves 711. One cylinder 7301 has two ends connected to the two U-shaped grooves 711 respectively. The two vertical inner walls of the U-shaped grooves 711 are respectively located on both sides of the top of the high-pressure water cleaner 600. The vertical inner wall of the lower U-shaped groove 711 is located between the lower cylinder 7301 and the top of the high-pressure water cleaner 600. The adaptive lifting mechanism 730 also includes a piston rod 7305, a spring 7306, an elastic airbag 7307, two push plates 7308, and two positioning blocks 7309. The lifting plate 7302 has an installation cavity 73021 inside. The two vertical inner walls of the float 7304 are... The cylinder has evenly distributed positioning grooves 73041. The mounting cavity 73021 is connected to the positioning grooves 73041. Two piston rods 7305 are slidably connected inside the cylinder barrel 7301. One end of the piston rod 7305, opposite to the U-shaped groove 711, passes through the cylinder barrel 7301 and the U-shaped groove 711 and contacts the U-shaped groove 711. A spring 7306 is located between the two piston rods 7305 and inside the cylinder barrel 7301. An elastic airbag 7307 is located inside the mounting cavity 73021, with one end connected to the cylinder barrel 7301. The connection between the elastic airbag 7307 and the cylinder barrel 7301 is always located at the two piston rods. Between 7305, push plates 7308 are slidably connected to the inside of mounting cavity 73021. Two push plates 7308 are symmetrically fixed to both ends of elastic airbag 7307. Two positioning blocks 7309 are respectively fixed to the opposite ends of the two push plates 7308, and the positioning blocks 7309 are aligned with the adjacent positioning groove 73041. Before the hollow slag removal mechanism 740 passes through the spray range of the high-pressure water cleaner 600, the piston rod 7305, located inside the U-shaped groove 711, slides out of the U-shaped groove 711. At this time, under the squeezing action of the U-shaped groove 711, the piston rod 7305 moves into the cylinder 7301, and the air inside the cylinder 7301 is squeezed into the connected... In the elastic airbag 7307, the elastic airbag 7307 expands and simultaneously pushes the two push plates 7308 towards the outside of the mounting cavity 73021. The push plates 7308 drive the connected positioning block 7309 through the mounting cavity 73021 and engage with the corresponding positioning groove 73041. Even if high-pressure water impacts the float 7304 and the hollow slag removal mechanism 740, the float 7304 and the hollow slag removal mechanism 740 are firmly locked on the surface of the lifting plate 7302. This makes the hollow slag removal mechanism 740 operate more stably and prevents the slag from being spilled during shaking, thereby improving the slag removal stability of the hollow slag removal mechanism 740.

[0055] The scum cleaning device 700 also includes a pressing bar 760, which is fixedly connected to the inner top wall of the mounting box 710. The pressing bar 760 is located on the side of the U-shaped channel 711 facing away from the screw feeder 200 and on the inner top wall of the collection net box 750. The adaptive lifting mechanism 730 also includes a pressing valve 7310 and an air guide pipe 7311. The pressing valve 7310 is fixedly connected to one end of the anti-detachment plate 7303 facing away from the cylinder 7301. One end of the upper pressing valve 7310 contacts the pressing bar 760, and one end of the pressing valve 7310 is connected to the elastic air bag 73. 07 is connected, and the air guide pipe 7311 is fixedly connected to one end of the anti-detachment plate 7303. One end of the air guide pipe 7311 is connected to the pressing valve 7310, and the other end of the air guide pipe 7311 faces the hollow slag removal mechanism 740. When the adaptive lifting mechanism 730 moves below the pressing bar 760, the pressing valve 7310 is blocked by the pressing bar 760 and is squeezed open. At this time, the elastic airbag 7307 is connected to the air guide pipe 7311 through the opened pressing valve 7310. The air guide pipe 7311 quickly guides the compressed air to the hollow slag removal mechanism 740, and the airflow passes through... During the process of the perforated slag removal mechanism 740, the floating slag adhering to the inner wall of the perforated slag removal mechanism 740 is blown away, making the perforated slag removal mechanism 740 cleaner and avoiding a large amount of floating slag residue on the surface of the perforated slag removal mechanism 740, thereby ensuring the subsequent slag removal effect of the perforated slag removal mechanism 740; when the pressing valve 7310 is opened, the elastic airbag 7307 quickly deflates, and the elastic airbag 7307 pulls the two push plates 7308 at the same time. The push plates 7308 drive the positioning block 7309 to quickly separate from the positioning groove 73041 and retract into the installation cavity 73. Inside 021, the float 7304 is simultaneously unobstructed, and the float 7304 drives the hollow slag removal mechanism 740 to quickly descend to the lowest point along the lifting plate 7302. This can shorten the height difference between the hollow slag removal mechanism 740 and the collection net box 750, thereby reducing the impact force of the slag falling into the collection net box 750. This not only improves the effective collection rate of the collection net box 750 for slag and prevents the slag from jumping out of the collection net box 750 under the action of collision, but also reduces the impact force of the slag on the collection net box 750, making the operation of the collection net box 750 more stable.

[0056] The adaptive lifting mechanism 730 also includes evenly distributed elastic diaphragm flaps 7312. The elastic diaphragm flaps 7312 are fixedly connected to the inner wall of the air guide tube 7311. The elastic diaphragm flaps 7312 are fixedly connected to the inner wall of the air guide tube 7311 in a ring around the axis of the air guide tube 7311. Adjacent elastic diaphragm flaps 7312 abut against each other. All elastic diaphragm flaps 7312 together form a pointed cone shape facing away from the anti-detachment plate 7303. When water from the outside rushes into the air guide tube 7311, adjacent elastic diaphragm flaps 7312 press against each other. At this time, all elastic diaphragm flaps 7312 together form a pointed cone-shaped sealing structure to block the water from the outside of the air guide tube 7311. When compressed gas rushes out of the air guide tube 7311, adjacent elastic diaphragm flaps 7312 do not abut against each other. The airflow can squeeze and deform the elastic diaphragm flaps 7312, so that the airflow can rush out quickly between the adjacent elastic diaphragm flaps 7312.

[0057] The adaptive lifting mechanism 730 also includes a one-way valve 7313, which is fixedly connected to and communicates with the surface of the cylinder 7301. The blocking direction of the one-way valve 7313 is the same as the direction from the cylinder 7301 to the one-way valve 7313. When the piston rod 7305 enters the interior of the U-shaped groove 711, the spring 7306 simultaneously pushes both piston rods 7305 outward, so that the piston rods 7305 are tightly pressed against the U-shaped groove 711, while the air inside the cylinder 7301... When the pressure drops, outside air can enter the cylinder 7301 through the one-way valve 7313, keeping the air pressure inside the cylinder 7301 normal. When the piston rod 7305 moves from inside the U-shaped groove 711, the two piston rods 7305 work together to compress the air inside the cylinder 7301. At this time, the one-way valve 7313 prevents the air inside the cylinder 7301 from flowing out through the one-way valve 7313, so that the air can be compressed and squeezed into the elastic air bag 7307.

[0058] Both vertical inner walls of the U-shaped groove 711 are inclined toward the screw feeder 200. The adaptive lifting mechanism 730 also includes two ball bearings 7314, which are rotatably connected to the opposite ends of the two piston rods 7305. This allows the piston rods 7305 to enter the U-shaped groove 711 more smoothly and reduces the probability of the piston rods 7305 getting stuck inside the U-shaped groove 711.

[0059] like Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 11As shown, the hollow-type slag removal mechanism 740 includes an arc-shaped mesh box 741, a round shaft 742, an L-shaped mesh plate 743, a spring piece 744, and an anti-detachment strip 745. The arc-shaped mesh box 741 is fixedly connected to one end of the float 7304, with the opening of the arc-shaped mesh box 741 facing away from the float 7304. The round shaft 742 is rotatably connected to the inside of the arc-shaped mesh box 741. The L-shaped mesh plate 743 is rotatably connected to the surface of the round shaft 742. The spring piece 744 is fixedly connected to the surface of the round shaft 742 and the L-shaped mesh plate 745. Between the L-shaped mesh plates 743, an anti-detachment strip 745 is fixedly connected to the inner wall of the arc-shaped mesh box 741. One end of the anti-detachment strip 745 contacts the L-shaped mesh plate 743. The spring piece 744 always applies a pushing force to the L-shaped mesh plate 743 towards the anti-detachment strip 745. The scum cleaning device 700 also includes a rack 770, which is fixedly connected to the inner top wall of the mounting box 710. The rack 770 is not only set between the pressing strip 760 and the U-shaped groove 711, but also has... The L-shaped mesh plate 743 is positioned between the end of the pressing bar 760 facing away from the screw feeder 200 and the end of the pressing bar 760 facing the screw feeder 200. One end of the upper L-shaped mesh plate 743 contacts the rack 770, which is positioned directly above the collecting mesh box 750. As the L-shaped mesh plate 743 passes through the rack 770, the rack 770 continuously blocks the L-shaped mesh plate 743. The L-shaped mesh plate 743 rotates due to the rack 770's blocking mechanism, and the spring piece 744 interacts with the L-shaped mesh plate 743 and the rack. The reciprocating motion of 770 after disconnection and reset can shake off and remove impurities trapped on the surface of L-shaped mesh plate 743 and inside arc-shaped mesh box 741, thereby improving the overall cleanliness of the hollow slag removal mechanism 740. In addition, the rack 770 can also press the arc-shaped mesh box 741 down to the lowest point again through L-shaped mesh plate 743, further reducing the impact force of scum on collection mesh box 750 and the probability of scum jumping out of collection mesh box 750 due to impact force.

[0060] The scum removal device 700 also includes a guide bucket 780, which is fixedly connected to the inside of the mounting box 710. The lower opening of the guide bucket 780 is connected to the collection net box 750. The guide bucket 780 can not only guide scum falling from a larger area into the collection net box 750, but also increase the height of the scum jumping out of the collection net box 750, thereby avoiding the probability of the scum falling back into the water.

[0061] It should be noted that the bubble cleaner 100, screw feeder 200, first mesh belt conveyor 300, second mesh belt conveyor 400, high-pressure water cleaner 600, and chain conveyor 720 mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. At the same time, the bubble cleaner 100, screw feeder 200, first mesh belt conveyor 300, second mesh belt conveyor 400, high-pressure water cleaner 600, and chain conveyor 720 can be powered by built-in power supply or by mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
