Description

Technical Field

[0001] The invention relates to the technical field of material cleaning, and in particular to a bubble cleaning device. Background Art

[0002] The bubble cleaning machine mainly uses the pressure generated when bubbles form, expand and quickly collapse in water, as well as the strong shear force and liquid flow generated thereby, to peel off, disperse and suspend stains, thereby achieving a cleaning effect. The bubble cleaning machine is widely used in the cleaning process of fruits and vegetables. The circulating water is formed by a high-pressure water pump, and air is input into the bottom of the tank to form bubbles. The bubbles drive the water flow to tumble and thus drive the raw materials to tumble, achieving the purpose of cleaning. This method not only has a good cleaning effect, but also can save a lot of cleaning water.

[0003] The Chinese patent application with application publication number CN114951117A discloses a raw material bubble disinfection and cleaning machine, including a cleaning box, an inclined placing table is installed inside the cleaning box, a plurality of equally spaced spray mechanisms are installed on the upper side of the placing table inside the cleaning box, a bubble generator is installed inside the placing table, and the output end of the bubble generator extends to the upper side of the placing table to transport bubbles to the water inside the cleaning box. The food raw material is transported to the inside of the cleaning box, the raw material flows along the placing table, the bubble generator generates bubbles to clean the raw material, and the spray mechanism sprays from the top of the raw material.

[0004] When the raw material is heavy, such as potatoes that are large in both volume and weight, it may be more difficult for the bubbles and water flow to roll over, resulting in inadequate cleaning, especially in certain areas of the raw material where dead corners may be formed. Summary of the invention

[0005] The present invention provides a bubble cleaning device, aiming to solve the problem in the related art that heavy raw materials may lead to insufficient cleaning and form cleaning dead corners.

[0006] The bubble cleaning device of the present invention includes a cleaning box and a material separation mechanism. The cleaning box has a cleaning trough, and the cleaning trough is provided with a conveyor, a spray mechanism located above the conveyor and a bubble generator located below the conveyor. The material separation mechanism includes a plurality of material separation units arranged at intervals along the moving direction of the conveyor, and the material separation unit includes a partition and a material removal member. The partition is provided on the conveying surface of the conveyor, and the material removal member is rotatably embedded in the partition and can cause heavy materials on the conveying surface to roll when it rotates; a sliding member is elastically slidably connected to the partition, and a transmission member is connected between the sliding member and the material removal member so that when the sliding member slides, the material removal member is driven to rotate; the inner wall of the cleaning box is provided with protrusions distributed at intervals along the moving direction of the conveyor, and a wedge structure is provided between the protrusion and the sliding member so that the sliding member can slide when passing through any of the protrusions.

[0007] The effect is that when the material-pickling piece rotates, it can expose the heavy materials on the conveying surface from the partition and pry them, thereby realizing the tumbling of the heavy materials. After the heavy materials push each other, the heavy materials between two adjacent partition units can tumble, so that each area of ​​the heavy materials can be washed in sequence by the spray mechanism, reducing the generation of cleaning dead corners and making the cleaning more complete. In addition, combined with the bubble effect of the bubble generator, the heavy materials have a tendency to float up, which is more conducive to the flushing of the spray mechanism.

[0008] Preferably, the material-moving member comprises a central axis and a material-moving rod, wherein the central axis extends along the thickness direction of the conveyor and is rotatably arranged on the partition, and a plurality of the material-moving rods are arranged at intervals along the thickness direction of the conveyor and are connected to the central axis in the middle.

[0009] The effect is that the arrangement of multiple material shifting rods increases the shifting range of heavy materials and improves the tumbling effect of heavy materials.

[0010] Preferably, the sliding direction of the slide is consistent with the width direction of the conveyor, and the transmission member includes a gear provided on the central shaft and a rack provided on the slide, and the gear is meshed with the rack.

[0011] Preferably, the wedge-shaped structure comprises a wedge-shaped surface provided on the protrusion and / or the sliding member, and the wedge-shaped surface is used to force the sliding member to slide when the sliding member passes over the protrusion.

[0012] Preferably, a support plate is slidably mounted on the wall of the cleaning box along the width direction of the conveyor, the protrusion is connected to the support plate, and a driving member for driving the support plate to slide is provided on the cleaning box.

[0013] The effect is that the support plate can drive the protrusion to move when sliding, thereby controlling the extension size of the protrusion into the inner side of the cleaning box, thereby controlling the sliding stroke of the slide, and then controlling the rotation amplitude of the material tapping rod, so that heavy materials of different weights can be adaptively adjusted to enhance the adaptability effect.

[0014] Preferably, an elastically twistable flapping plate is provided on the partition, the flapping plate is hollow and can protrude above the partition, and the inner wall of the cleaning box is provided with a plurality of stoppers distributed at intervals along the moving direction of the conveyor, and the stoppers are used to block the flapping plate when the flapping plate passes by, so as to deflect it and knock the light materials floating on the water surface into the water.

[0015] The effect is that the flapping plate can soak the light materials in water when flapping, ensuring the full dissolution of dirt and improving the cleaning effect. When the flapping plate passes over the stopper, it quickly resets under the action of elastic force, and the flapping plate can lift the light materials and help them turn over, which can avoid excessive washing and damage of one side of the material due to long-term washing, and ensure that both sides of the material can be washed alternately to ensure uniform cleaning.

[0016] Preferably, a material guide plate capable of elastic twisting is provided at the entrance of the cleaning box, and the degree of twisting of the material guide plate is determined according to the weight of the material; a material blocking member is rotatably provided on the cleaning box and is located on the side of the material guide plate close to the cleaning trough, and a power device for driving the material blocking member to deflect is provided on the cleaning box.

[0017] Preferably, the partition is elastically slidably connected with a sliding support along the thickness direction of the conveyor, the flapping plate is rotatably connected to the sliding support, and a torsion spring is also connected between the two; a guide track is fixedly provided on the inner wall of the cleaning box, and the guide track includes a straight track section and a V-shaped track section. There are two straight track sections and they are arranged at intervals along the thickness direction of the conveyor. Both of the two straight track sections extend along the movement direction of the conveyor and are transitionally connected by a V-shaped track section at the starting end. A mating piece is provided on the sliding support. When the sliding support passes through the guide plate, the guide plate presses down the sliding support through the flapping plate so that the mating piece enters one side of the V-shaped track section.

[0018] Preferably, a strip frame is fixedly provided in the cleaning tank and is located between the bubble generator and the conveyor. The strip frame is provided with a plurality of inclined blocks arranged at intervals along the moving direction of the conveyor. The inclined blocks are used to squeeze the beating plate when the beating plate passes by, so that the beating plate moves back and vibrates.

[0019] The effect is that under the action of vibration force, dirt and impurities on the surface of the flapping board can fall off, thereby achieving self-cleaning of the flapping board.

[0020] Preferably, the conveyor comprises a straight conveying section immersed in water and an inclined conveying section with a top end protruding above the water surface, and the outlet of the cleaning box is adjacent to the top end of the inclined conveying section.

[0021] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0022] Through the action of multiple protrusions, the intermittent rotation of the material-dispensing member is realized. When rotating, the material-dispensing member can be exposed from the partition and move the heavy materials on the conveying surface, thereby realizing the tumbling of the heavy materials. After the heavy materials push each other, the heavy materials between two adjacent material-dispensing units can tumble, so that each area of ​​the heavy materials can be washed in sequence by the spray mechanism, reducing the generation of cleaning dead corners and making the cleaning more complete. In addition, combined with the bubble effect of the bubble generator, the heavy materials have a tendency to float up, which is more conducive to the flushing of the spray mechanism.

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] Combine the following Figures 1 to 8 The bubble cleaning device of the present invention is described.

[0039] like Figure 1 to Figure 2 As shown, the bubble cleaning device of the present invention includes a cleaning box 1, a conveyor 2, a spray mechanism 3, a bubble generator 4 and a material isolation mechanism 5.

[0040] The cleaning box 1 has a cleaning tank 11 for containing clean water. The inlet 12 of the cleaning box 1 is located on the left side of the cleaning tank 11, and the outlet 13 is located on the right side of the cleaning tank 11. Fruit and vegetable materials enter the cleaning tank 11 through the inlet 12 and are discharged from the cleaning tank 11 through the outlet 13. In order to achieve a better cleaning effect of the materials in the cleaning tank 11, an appropriate amount of detergent can be added to the cleaning tank 11.

[0041] The conveyor 2 is arranged in the cleaning tank 11, and includes a straight conveying section 21 immersed in water and an inclined conveying section 22 with the top protruding above the water surface. The inclined conveying section 22 is located on the right side of the straight conveying section 21 and the top is adjacent to the outlet 13 of the cleaning box 1. This makes it convenient for the conveyor 2 to transport materials from left to right. The materials can be transported above the water surface, so that the materials have a drainage process after leaving the water, and at the same time, the clean water is prevented from flowing to the outlet 13 with the materials, ensuring the retention effect of the clean water in the cleaning tank 11 and preventing it from being lost. When the material moves to the top of the inclined conveying section 22, the material slides to the outlet 13 and is discharged. It should be noted that the conveyor 2 can be a mesh belt conveyor, a mesh chain conveyor, a chain conveyor, etc.

[0042] The spray mechanism 3 is arranged in the cleaning tank 11 and is located above the conveyor 2. Specifically, the spray mechanism 3 includes a plurality of spray units 31 arranged at equal intervals along the moving direction of the conveyor 2. The spray unit 31 includes a spray pipe 311 extending along the width direction of the conveyor 2 and fixed on the cleaning box 1 at both ends, and spray heads 312 evenly arranged on the spray pipe 311 along the width direction of the conveyor 2. The spray pipe 311 is used to connect to an external water source and spray water through the spray head 312. The spray head 312 realizes the flushing of the material in the cleaning tank 11.

[0043] The bubble generator 4 is disposed in the cleaning tank 11 and is located below the conveyor 2. Specifically, the bubble generator 4 is in the shape of a mesh tube and has a plurality of bubble generating holes 41 discretely arranged on a horizontal plane, so that the formed bubbles are distributed more evenly and widely.

[0044] Continue to refer Figures 1 to 5 The material separation mechanism 5 includes a plurality of material separation units 51 arranged at equal intervals along the moving direction of the conveyor 2. The material separation unit 51 includes a partition 511 and a material-dispensing member 512. The partition 511 is fixedly mounted on the conveying surface 23 of the conveyor 2. The partitions 511 in the plurality of material separation units 51 divide the conveying surface 23 into a plurality of sections, each section is used to accommodate a certain amount of material, thereby realizing separate conveying of the material. In addition, the partition 511 has a boosting effect on the conveying of the material, ensuring that the material is reliably conveyed to the outlet 13. The material-dispensing member 512 is rotatably embedded in the partition 511 and can roll over the heavy material on the conveying surface 23 when rotating. The material-dispensing member 512 includes a central axis 512a and a material-dispensing rod 512b. The central axis 512a extends along the thickness direction of the conveyor 2 and is rotatably penetrated on the partition 511. The plurality of material-dispensing rods 512b are arranged at equal intervals along the thickness direction of the conveyor 2 and the middle part is fixedly connected to the central axis 512a. It should be noted that the number of the material-diverting members 512 is not limited to a single one, and may also be a plurality of members arranged along the width direction of the conveyor 2 , thereby increasing the effective range of the material-diverting members 512 .

[0045] The partition 511 is slidably equipped with a slide 513 along the width direction of the conveyor 2, and the slide 513 is connected to the partition 511 through a return spring 513a. A transmission member is connected between the slide 513 and the material-dispensing member 512, and the transmission member includes a gear 512c provided on the central axis 512a and a rack 513b provided on the slide 513, and the gear 512c meshes with the rack 513b. The inner wall of the cleaning box 1 is provided with convex blocks 14 distributed at equal intervals along the moving direction of the conveyor 2, and a wedge structure is provided between the convex block 14 and the slide 513, and the wedge structure includes a wedge surface 513c, and there are two wedge surfaces 513c, which are respectively provided on the convex block 14 and the slide 513.

[0046] When conveying materials, the conveyor 2 moves with the partition 511 synchronously. When the slide 513 passes through any protrusion 14, the wedge surface 513c on the slide 513 and the wedge surface 513c on the protrusion 14 are squeezed. Under the squeezing action, the slide 513 slides, and then drives the central axis 512a to rotate through the rack 513b and the gear 512c. The central axis 512a drives the material-moving rod 512b to rotate. When the material-moving rod 512b rotates, it can expose from the partition 511 and move the heavy materials on the conveying surface 23, thereby realizing the tumbling of the heavy materials. After the heavy materials push each other, the heavy materials between the two adjacent material-moving units 51 can tumble, so that each area of ​​the heavy materials can be washed in turn by the spray head 312, reducing the generation of cleaning dead corners and making the cleaning more complete. In addition, combined with the bubble action of the bubble generator 4, the heavy materials have a tendency to float, which is more conducive to the washing of the spray head 312.

[0047] Key References Figures 5 to 7 The wall of the cleaning box 1 has an interlayer cavity, in which a support plate 15 is slidably mounted along the width direction of the conveyor 2, and the protrusion 14 extends into the interlayer cavity and is fixedly connected to the support plate 15. The cleaning box 1 is provided with a driving member for driving the support plate 15 to slide, and the driving member can be a screw 16 threadedly penetrated on the wall of the cleaning box 1, one end of the screw 16 extends into the interlayer cavity and is rotatably connected to the support plate 15, and the other end protrudes to the outside of the cleaning box 1 and is provided with a handle 161. The operator can control the spiral movement of the screw 16 through the handle 161, and the screw 16 drives the support plate 15 to move, and the support plate 15 drives the protrusion 14 to move, thereby controlling the extension size of the protrusion 14 on the inner side of the cleaning box 1, thereby controlling the sliding stroke of the slide 513, and then controlling the rotation amplitude of the material shifting rod 512b, so that adaptive adjustment can be made for heavy materials of different weights, that is, for heavy materials with relatively large weight, the rotation amplitude of the material shifting rod 512b can be larger, and for heavy materials with relatively small weight, the rotation amplitude of the material shifting rod 512b can be smaller, thereby enhancing the adaptation effect.

[0048] When the material is light, such as some vegetable branches and leaves, light fruits, etc., the material tends to float on the water surface, so it is difficult for the material to be immersed in the water, and the dirt on it cannot be fully eliminated, resulting in poor cleaning effect. In addition, the spray head 312 rinses one side of the material for a long time, which may lead to excessive cleaning and even damage the surface of the material. The other side of the material cannot be rinsed by the spray head 312, resulting in uneven cleaning.

[0049] To this end, continue to refer to Figures 2 to 6 A sliding support 514 is slidably mounted on the partition 511 along the thickness direction of the conveyor 2. The sliding support 514 is connected to the partition 511 through a centering spring 514a. A hollow beating plate 515 is rotatably connected to the sliding support 514, and a torsion spring is also connected between the two.

[0050] The inner wall of the cleaning box 1 is fixedly provided with a guide track 17, which includes a straight track section 171 and a V-shaped track section 172. There are two straight track sections 171 and they are arranged at intervals along the thickness direction of the conveyor 2. The straight track section 171 extends along the movement direction of the conveyor 2 and the starting end is close to the entrance 12 of the cleaning box 1. The starting ends of the two straight track sections 171 are transitionally connected through the V-shaped track section 172. It should be noted that a plurality of protrusions 14 are provided between the two straight track sections 171, and a plurality of stoppers 18 are fixedly provided on the inner wall of the cleaning box 1 and are distributed at equal intervals along the movement direction of the conveyor 2. The plurality of stoppers 18 are located above the two straight track sections 171. A matching member 514b is provided on the sliding support 514.

[0051] When the sliding support 514 passes through the guide track 17 from left to right, the matching piece 514b will be guided to one side by the V-shaped track section 172. If the matching piece 514b enters the lower straight track section 171, the sliding support 514 will move downward, the centering spring 514a will be compressed, and the hollow area of ​​the flapping plate 515 is used for the material-moving rod 512b to rotate through. If the matching piece 514b enters the upper straight track section 171, the sliding support 514 will move upward, the centering spring 514a will be stretched, and the flapping plate 515 will protrude above the partition 511. When the flapping plate 515 continues to move to the right and passes through the stopper 18, the stopper 18 blocks the flapping plate 515, and the flapping plate 515 deflects and gently pats the light materials floating on the water surface into the water to achieve immersion, ensure the full dissolution of dirt, and improve the cleaning effect. When the flapping plate 515 passes over the stopper 18, it quickly returns to its original position under the action of the torsion spring, and the flapping plate 515 can lift the light material and help it turn over, thus avoiding excessive washing of one side of the material for a long time and causing damage, and ensuring that both sides of the material can be washed alternately to ensure uniform washing. Multiple stoppers 18 allow the flapping plate 515 to perform multiple groups of flapping actions during movement, which not only prolongs the soaking time of the material, but also ensures the turning frequency of the material.

[0052] To realize the automatic lane change of the matching member 514b, continue to refer to Figures 2 to 8 , an inclined material guide plate 121 is hinged at the entrance 12 of the cleaning box 1, and a torsion spring 121a is also connected between the material guide plate 121 and the cleaning box 1. The torsion spring 121a is used to provide a buffer for the material when the material falls into the material guide plate 121, thereby reducing the structural damage of the material guide plate 121. The material guide plate 121 determines the degree of downward deflection according to the weight of the material, that is, when the material is heavier, the deflection degree of the material guide plate 121 is larger, and when the material is lighter, the deflection degree of the material guide plate 121 is smaller. A material blocking member 122 is rotatably arranged on the cleaning box 1. The material blocking member 122 is close to the inner side of the cleaning tank 11 relative to the material guide plate 121 and is used to block the falling of the material on the material guide plate 121. The cleaning box 1 is provided with a power device 123 for driving the deflection of the material blocking member 122, and the power device 123 can directly use a motor.

[0053] When the sliding support 514 passes the guide plate 121 from left to right, the accumulated materials will squeeze the flapping plate 515 through the guide plate 121, causing the flapping plate 515 to move downward, thereby pushing the sliding support 514 downward. If the material on the guide plate 121 is heavy, or if it is a heavy material, the sliding support 514 moves downward by a large amount, and the matching piece 514b is located at the lower side of the V-shaped track section 172. When the matching piece 514b continues to move, it will enter the lower straight track section 171, thereby realizing the material-moving action of the material-moving rod 512b. If the material on the guide plate 121 is light, or if it is a light material, the sliding support 514 moves downward by a small amount, and the matching piece 514b is located at the upper side of the V-shaped track section 172. When the matching piece 514b continues to move, it will enter the upper straight track section 171, thereby realizing the flapping action of the flapping plate 515.

[0054] After the flapping plate 515 performs multiple flapping actions, dirt and impurities will be stained on the surface, so as to realize automatic cleaning. Figure 2 and Figure 3 A strip frame 19 is fixedly provided in the cleaning tank 11 and is located between the bubble generator 4 and the conveyor 2 . A plurality of inclined blocks 191 are arranged at equal intervals along the moving direction of the conveyor 2 on the strip frame 19 .

[0055] When the flapping plate 515 is on the return journey, that is, when it is driven by the conveyor 2 to move from right to left, it will turn to the bottom of the conveyor 2. Under the action of its own weight, the flapping plate 515 and the sliding support 514 will hang down for a while. When the flapping plate 515 passes the inclined block 191, it will slide upward due to the squeezing action of the inclined block 191. The flapping plate 515 drives the sliding support 514 to move back upward. After passing the inclined block 191, the flapping plate 515 and the sliding support 514 fall again, thereby causing vibration. Under the action of the vibration force, the dirt and impurities on the surface of the flapping plate 515 can fall off, thereby realizing the self-cleaning of the flapping plate 515.

[0056] In other embodiments, the material-moving member 512 may be a blade, a blade, etc. The transmission member may be a shifting block provided on the slide 513 and the central axis 512a, and the effect of shifting the central axis 512a to rotate is achieved through the alignment contact between the shifting block on the slide 513 and the shifting block on the central axis 512a. The wedge-shaped surface 513c of the wedge-shaped structure may be set to one, which is provided on the protrusion 14 or the slide 513. The driving member may be an automatic control device such as a hydraulic rod, a cylinder, an electric push rod, etc. The flapping plate 515 and the guide plate 121 may be a rubber plate or a silicone plate, which realizes the effect of elastic torsion by its own elastic deformation.
