A conveying device for food cleaning processing

Abstract

The application discloses a conveying device for food cleaning processing, which is used for pushing food to surge away from a bearing plate through a large number of surging bubble clouds, and makes the bubble clouds act as the bearing plate, so that the food is prevented from falling to the lower side when a gap is opened between adjacent bearing plates; the bubble amount through the hole on the inclined bearing plate is far less than the bubble amount through the gap between the adjacent bearing plates, so that the local areas are differentiated in that the bubble impact force on the upper side of the gap on the bearing plate is large, and the bubble impact force on the upper side of the bearing plate is small; at this time, since the bearing plate continuously advances, the position of the gap continuously changes forward, the area with the large upper side impact force continuously changes forward, and the area with the small upper side impact force also continuously changes forward, so that the food in the area with the large impact force continuously advances along with the bearing plate under the impact force difference and the pushing force provided by the bubble impact, and the food is prevented from continuously advancing along with the bearing plate after leaving the bearing plate and always staying in the cleaning tank.

Description

TECHNICAL FIELD

[0001] The application relates to the technical field of food processing, and particularly relates to a conveying device for food cleaning and processing. BACKGROUND

[0002] The bubble cleaning machine is a high-efficiency cleaning device (mainly used for surface cleaning of food such as vegetables, fruits and meat) needed in the process of food cleaning and processing. The bubble cleaning machine mainly pumps clean water into a cleaning tank through a water pump. A conveying belt for circulating conveying is arranged in the cleaning tank through chain transmission or belt transmission. A large number of holes are arranged on the conveying belt. Food enters the cleaning tank through the conveying belt, and then leaves the cleaning tank along the continuously advancing conveying belt after cleaning. In this process, air is pumped into a bubble generator at the bottom of the cleaning tank through an air pump. Then, the bubble generator generates a large number of bubbles in water to form a bubble cloud. The bubble cloud rapidly surges upwards (the speed can reach 50-70 m / s). The bubble cloud reaches the top of the conveying belt through the dense holes on the conveying belt. Then, the bubbles break near the surface of the food, and strong impact force and shear force (including vortex) are generated to remove impurities on the surface of the food. When the bubbles break, the surrounding water is stirred to push the low-quality food to surge upwards to roll and clean the low-quality food. At the same time, the impurities removed from the food are pushed to the liquid surface under the impact of the broken bubbles, and then are discharged from the hole arranged on the side wall of the cleaning tank to the sewage tank and are discharged through the circulating water pump in the sewage tank.

[0003] The existing bubble cleaning machine adopts the mode that the bubble cloud floats upwards to make the bubbles contact the food again through the conveying belt. Therefore, a large number of bubbles are directly blocked by the position without holes on the conveying belt, so that a large number of bubbles cannot contact the food. As a result, the food contacts a limited amount of bubbles in unit time.

[0004] Therefore, the cleaning time needs to be prolonged to obtain effective cleaning effect. SUMMARY

[0005] The application provides a conveying device for food cleaning and processing. The conveying device has the advantages that the bearing plate is upwardly inclined to open a gap, the bubble cloud surges upwards and impacts the food in a large amount through the gap, the food rolls upwards and moves away from the bearing plate under the impact of the bubble cloud, the bubble cloud supports the food as the "bearing plate", the impact force difference is formed by the difference between the amount of the bubble cloud at the gap and the bearing plate, the food is driven to move forwards by the impact force difference, the fence plate changes the upward amount of the bubble cloud again, and the upward amount of the bubble cloud is continuously changed to make the food above be layered.

[0006] In order to achieve the above object, the technical scheme adopted by the present application is as follows: a conveying device for food cleaning and processing, comprising a reinforcing wall, the reinforcing wall is divided into reinforcing wall I, reinforcing wall II and reinforcing wall III, a positioning belt is arranged in the reinforcing wall, and a conveying belt is arranged between the two symmetrical positioning belts; the conveying belt comprises uniformly distributed rotating rods and bearing plates connected with the rotating rods, and is used for bearing and transporting food, the two ends of the rotating rod are arranged in the two positioning belts respectively, and a large number of holes are formed in the bearing plate and used for passing the upwelling bubble cloud; a limiting groove is formed in the inner side of the reinforcing wall, an expansion area is formed in the position of the reinforcing wall II, the height value of the expansion area is greater than that of the limiting groove, a torsional spring is arranged at the connection position of the rotating rod and the positioning belt, and is used for driving the bearing plate to tilt and rotate to open a gap in the expansion area.

[0007] Preferably, a belt conveying groove is formed in the reinforcing wall, a transmission belt is arranged in the belt conveying groove, and the outer side of the transmission belt is connected with the positioning belt, so as to drive the conveying belt to move.

[0008] Preferably, a reset area is arranged on one side of the expansion area, an arc-shaped edge with a high upper position and a low lower position is formed at the top end of the reset area, and the arc-shaped edge is used for guiding the tilted bearing plate to rotate downward and reset.

[0009] Preferably, a transition area is formed at the corner of the limiting groove, and the distance value of the two sides of the transition area is greater than that of the limiting groove, so as to provide space for the rotation of the bearing plate at the corner.

[0010] Preferably, the thickness value of the bearing plate and the diameter value of the rotating rod are equal to the distance value of the two sides of the limiting groove, and the two sides of the bearing plate are located in the limiting groove, so as to limit the position of the bearing plate.

[0011] Preferably, a uniformly distributed fence plate is arranged above the expansion area, the two ends of the fence plate are connected with the two reinforcing wall IIs on the two sides respectively, a large number of holes are formed in the fence plate, the width value of the fence plate is less than half of the gap width value, a part of the upwelling bubble cloud is hindered, and the distance between the adjacent fence plates is greater than the width value of the bearing plate, so as to reduce the hindering area of the bubble cloud.

[0012] The conveying device for food cleaning and processing provided by the present application sets an expansion area on the side wall in the cleaning tank through the reinforcing wall, so that the bearing plate loses the limitation of the limiting groove after entering this area, the torsional spring drives the rotating rod and the bearing plate to swing upward until the front end of the bearing plate abuts against the top end of the expansion area, the adjacent bearing plates open an inclined gap, a large amount of bubble cloud below can quickly reach the upper side of the bearing plate through this gap and contact the food, and the hindering effect of the conveying belt on the bubble cloud is reduced.

[0013] Meanwhile, the large amount of bubble clouds upwelling will push the food upwelling away from the bearing plate, so that the bubble clouds act as "bearing plate", avoiding the food falling to the lower part when the gap between the adjacent bearing plates is opened, the amount of bubbles passing through the hole of the inclined bearing plate is far less than the amount of bubbles passing through the gap between the adjacent bearing plates, resulting in the difference between the local area above the gap where the bubble impact force is large and the local area above the bearing plate where the bubble impact force is small, at this time, since the bearing plate continues to advance, the position of the gap changes forward continuously, the area above with large impact force also changes forward continuously, and the area above with small impact force also changes forward continuously, so that the food in the area with large impact force continuously follows the bearing plate to advance under the impact of the impact force difference and the pushing force provided by the bubble impact, avoiding the food that cannot continuously follow the bearing plate to advance after leaving the bearing plate and always staying in the cleaning tank.

[0014] Meanwhile, in the process of pushing the food forward by the bubble clouds, the food will pass above the fence plate, at this time, the fence plate has a blocking effect on the bubble clouds upwelling below, resulting in a decrease in the amount of bubble clouds above the fence plate, leading to a decrease in the bubble cloud impact force on the food above the fence plate, so that the food below (referring to the food below in the same area pushed up by the bubble clouds, here referring to the food above the fence plate) falls due to the extrusion of the food above and the decrease in the amount of bubble clouds upwelling below, and the food above is separated, thereby avoiding the food in the same area from being stacked together to form an obstacle and the problem of reduced cleaning force of the bubble clouds on individual food.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0025] Embodiment one

[0026] Please refer to Figures 2 to 3 A food cleaning and processing conveying device, comprising a bubble cleaning machine for cleaning food, and symmetric reinforcing walls are fixedly connected to the inner side walls of both ends of the bubble cleaning machine through bolts, the reinforcing walls are divided into an inclined reinforcing wall I 1, an inclined reinforcing wall III 3, and a reinforcing wall II 2 located in the cleaning tank of the bubble cleaning machine.

[0027] Please refer to Figures 1 to 4 A belt conveying groove 4 is formed in the reinforcing wall, and a transmission belt 6 is movably sleeved in the belt conveying groove 4, so that the transmission belt 6 can move directionally under the limitation of the belt conveying groove 4. The outer side of the transmission belt 6 is fixedly connected with a positioning belt 61, and a conveying belt is arranged between the two symmetric positioning belts 61. The conveying belt comprises uniformly distributed rotating rods 7 and bearing plates 8 welded with the rotating rods 7. The two ends of each rotating rod 7 are movably sleeved in the two positioning belts 61. The bearing plate 8 is provided with dense holes, so that when the transmission belt 6 drives the positioning belt 61 to move synchronously, the rotating rod 7 and the bearing plate 8 can move synchronously, so that the bearing plate 8 can transport the food into the cleaning tank of the bubble cleaning machine to accept the cleaning of the bubble cloud output upward by the bubble generator below, and then transport the food away by the moving bearing plate 8 after the cleaning is completed.

[0028] Please refer to Figures 1 to 4The inner side of the reinforcing wall is provided with a limiting groove 5, the limiting groove 5 is provided with an expansion area 51 and a reset area 52 at the position of the reinforcing wall II 2, the height value of the expansion area 51 is greater than the height value of the limiting groove 5, the movable sleeve joint of the rotating rod 7 and the positioning belt 61 is movably sleeved with a torsional spring 9, so that the restriction of the bearing plate 8 above the expansion area 51 is reduced after the bearing plate 8 moves into the expansion area 51, the energy stored torsional spring 9 drives the bearing plate 8 to rotate upward around the center line of the rotating rod 7 until the top end of the bearing plate 8 contacts the top end of the expansion area 51, and the bearing plate 8 is inclined, the gap between the two adjacent bearing plates 8 is staggered to form a gap, so that a large amount of bubble cloud below can quickly reach the upper side of the bearing plate 8 and contact the food through the gap, reducing the blocking effect of the entire conveying belt on the bubble cloud, it should be noted that before the bearing plate 8 enters the expansion area 51, it has entered the cleaning tank, at this time the bubble cloud flowing upwards through the bearing plate 8 will push the food upwards away from the bearing plate 8, when the bearing plate 8 is inclined, the bubble cloud flowing upwards through the gap will push the upward moving food to move upward again, the inclination angle of the bearing plate 8 at the expansion area 51 is not greater than sixty degrees, so that the bearing plate 8 can always have a contact surface directly contacting the bubble cloud flowing upwards below when it is inclined, so that part of the bubble cloud needs to pass through the dense holes of the bearing plate 8 to reach the upper side and contact the food, the bubble cloud passing through the bearing plate 8 to the upper side is small due to the obstruction of the bearing plate 8 and the damage to the bubbles, at this time a difference in the amount of bubbles is formed between the upper side of the gap and the upper side of the bearing plate 8, forming a local area difference between the upper side of the gap and the upper side of the bearing plate 8, at this time the food in the area with large impact force continuously moves forward with the bearing plate 8, avoiding the food from leaving the bearing plate 8 and continuously moving forward with the bearing plate 8, and always staying in the cleaning tank, the reset area 52 is connected with one side of the expansion area 51, the top end of the reset area 52 is provided with an arc-shaped edge with a high upper position and a low lower position, so that when the inclined bearing plate 8 moves to the reset area 52, the top end of the inclined bearing plate 8 will contact the arc-shaped edge at the top end of the reset area 52, gradually rotating downward around the center line of the rotating rod 7 to reset until it is in a horizontal state, at this time the torsional spring 9 is energized again, and the upward flowing bubble cloud gradually decreases, so that the food gradually falls back onto the bearing plate 8 and leaves the cleaning tank with the bearing plate 8, the limiting groove 5 is provided with a transition area 53 at the corner, the distance between the two sides of the transition area 53 is greater than the distance between the two sides of the limiting groove 5, since the bearing plate 8 is a rigid structure, the transition area 53 with a larger space at the corner will help the bearing plate 8 to smoothly turn.

[0029] The thickness value of the bearing plate 8 and the diameter value of the rotating rod 7 are equal to the interval value between the two sides of the limiting groove 5. The two sides of the bearing plate 8 are located in the limiting groove 5, so that the bearing plate 8 is limited by the interval of the limiting groove 5 to keep a stable state, and the stable transportation of the food is realized. The end of the bearing plate 8 away from the connected rotating rod 7 is close to the other rotating rod 7.

[0030] Example two

[0031] Please refer to Figures 5 to 6 On the basis of example one, the upper part of the expansion area 51 is provided with uniformly distributed fence plates 10. The two ends of the fence plate 10 are fixedly connected with the two reinforcing walls II 2 on the sides, and a large number of holes are formed in the fence plate 10. The width value of the fence plate 10 is less than half of the width value of the gap, and the interval between adjacent fence plates 10 is greater than the width value of the bearing plate 8. In the process of pushing the food forward by the bubble cloud, the food will pass above the fence plate 10. At this time, the fence plate 10 has a blocking effect on the bubble cloud that rises from below, so that the amount of bubble cloud above the fence plate 10 decreases, resulting in a decrease in the impact force of the bubble cloud on the food above the fence plate 10. The food located below (referring to the food located below in the same area pushed by the bubble cloud, which refers to the food above the fence plate) falls due to the extrusion of the food above and the decrease in the amount of bubble cloud rising from below, and the food above and below is stratified, so that the food in the same area can be separated, avoiding the accumulation of food in the same area to form an obstacle, and the problem of reducing the cleaning force of the bubble cloud on the single food. It should be noted that when the bearing plate 8 passes below the fence plate 10, the bubble cloud that has been reduced by the bearing plate 8 needs to be reduced again by the fence plate 10. When the gap passes below the fence plate 10, the bubble cloud passing through the gap only needs to be reduced once by the fence plate 10. The three different bubble reductions (single through the bearing plate 8, single through the fence plate 10, and simultaneously through the bearing plate 8 and the fence plate 10) and the gap bubble without reduction result in a variety of changes in the impact force of the food above, so that the food above is separated into multiple layers and cleaned in multiple directions, improving the cleaning effect.
