AI Technical Summary
[0004]在现有技术中，通常通过在散气桶内增加板体来增加蔗汁与空气的接触面积，但存在以下问题：当单纯在散气桶中增加板体来增加蔗汁与空气的接触面积时，蔗汁与空气接触的有效面积有所增大，但也减缓了蔗汁散气的速度，导致散气效率不高
在上述蔗汁散气桶中，对比距离地面较低的蔗汁散气桶，桶体经抬高架抬高后，蔗汁经入汁管流出时的重力势能增加，从而能够增加蔗汁在桶体内的流速，以此加快蔗汁在桶体内流动的速度；蔗汁在落到入汁托盘后得以分散，经入汁托盘分散的蔗汁再落到散气板上进行进一步分散，再经散气孔后呈多股蔗汁朝流出管流动，最终经流出管排出，在前述过程中，蔗汁在桶体内与空气接触的面积大大增加。可见，本实用新型能够通过加快蔗汁的流动速度及与空气接触的面积来提高散气效率。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of sugar production technology, specifically to a sugarcane juice aeration tank. Background Technology
[0002] During the sugar production process, non-condensable gases such as air and ammonia are carried in the sugarcane juice, including the neutralized juice before entering the neutralization sedimentation tank and the filtered juice before entering the filtrate sedimentation tank. These gases can disturb the settling of the sediment during the sugarcane juice sedimentation process. Therefore, a gas dissipation device is needed in the sugar production process to dissipate the non-condensable gases in the sugarcane juice before it enters the sedimentation tank.
[0003] Currently, the gas dispersing device used in sugar factories has a simple structure, resembling a barrel. The upper part has a juice inlet pipe, and the lower part has a juice outlet pipe. The upper part is open to the atmosphere. This gas dispersing barrel acts as a buffer. The juice stays in the gas dispersing barrel for a short time. The juice relies on the higher temperature inside the gas dispersing barrel to create a pressure difference with the atmospheric pressure outside the gas dispersing barrel, and the gas in the high-temperature juice naturally disperses into the atmosphere.
[0004] In existing technologies, the contact area between sugarcane juice and air is usually increased by adding plates inside the aeration tank. However, this has the following problems: when simply adding plates inside the aeration tank to increase the contact area between sugarcane juice and air increases the effective contact area between the sugarcane juice and air, it also slows down the aeration speed of the sugarcane juice, resulting in low aeration efficiency. Summary of the Invention
[0005] The present invention aims to solve one of the technical problems mentioned above by providing a sugarcane juice aeration tank, which can improve aeration efficiency by accelerating the flow rate of sugarcane juice and increasing the contact area with air.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A sugarcane juice aeration tank includes a lifting frame, a tank body, an exhaust pipe, a juice inlet pipe, a juice inlet tray, and an aeration plate. The lifting frame is erected on the ground, and the tank body is mounted on the lifting frame. The bottom of the tank body is provided with an outlet pipe, and the exhaust pipe is installed at the top of the tank body and communicates with the interior of the tank body. The juice inlet pipe is connected to the upstream of the process and extends into the upper part of the tank body. The juice inlet tray is located inside the tank body and below the juice inlet pipe. The aeration plate is located inside the tank body and on the side of the juice inlet tray opposite to the juice inlet pipe. The aeration plate has a through-hole for aeration.
[0007] Furthermore, the centerline of the end of the juice inlet tube used for juice dispensing coincides with the centerline of the barrel body.
[0008] Furthermore, the barrel body includes an upper barrel body and a flow guide ring plate. The flow guide ring plate is connected to the bottom of the upper barrel body, and the inner side of the flow guide ring plate forms an angle of 25° with the horizontal cross-section of the upper barrel body. The exhaust pipe is installed on the top of the upper barrel body away from the flow guide ring plate, and the outlet pipe is installed on the bottom of the flow guide ring plate away from the upper barrel body.
[0009] Furthermore, the diffuser plate protrudes in the direction of the exhaust pipe.
[0010] Furthermore, the air diffuser plate includes an arc-shaped plate and a connecting ring plate, the connecting ring plate being connected to the periphery of the arc-shaped plate and the connecting ring plate being connected to the inner side of the barrel body; the arc-shaped plate protrudes towards the exhaust pipe, and the air diffuser holes are evenly distributed on the arc-shaped plate.
[0011] Furthermore, the connecting ring plate is provided with a leakage hole.
[0012] Furthermore, the arc-shaped plate is recessed with a spiral groove, which extends spirally outward from the inside of the arc-shaped plate toward the inner side of the barrel body.
[0013] By adopting the above technical solution, this utility model has the following beneficial effects: In the aforementioned sugarcane juice aeration tank, compared to a tank lower than the ground, the increased gravitational potential energy of the juice flowing out through the inlet pipe after the tank is raised by the lifting frame increases the flow velocity of the juice within the tank, thus accelerating its movement. After falling onto the inlet tray, the juice is dispersed, then falls onto the aeration plate for further dispersion, and finally flows through the aeration holes in multiple streams towards the outlet pipe, ultimately being discharged. In this process, the surface area of the juice in contact with air within the tank is significantly increased. Therefore, this invention improves aeration efficiency by increasing the flow velocity of the sugarcane juice and the area of contact with air. Attached Figure Description

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0021] like Figures 1 to 3 As shown, a preferred embodiment of this utility model provides a sugarcane juice aeration tank, including a lifting frame 1, a tank body 2, an exhaust pipe 3, a juice inlet pipe 4, a juice inlet tray 5, and an aeration plate 6. The lifting frame 1 is erected on the ground, and the tank body 2 is mounted on the lifting frame 1. The bottom of the tank body 2 has an outlet pipe 23, and the exhaust pipe 3 is installed at the top of the tank body 2 and communicates with the interior of the tank body 2. The juice inlet pipe 4 is connected to the upstream of the process and extends into the upper part of the interior of the tank body 2. The juice inlet tray 5 is welded to the interior of the tank body 2 via channel steel and is located below the juice inlet pipe 4. The aeration plate 6 is located inside the tank body 2 on the side of the juice inlet tray 5 opposite to the juice inlet pipe 4, and the aeration plate 6 has a through-hole 611.
[0022] In the aforementioned sugarcane juice aeration tank, compared to a sugarcane juice aeration tank lower than the ground, after the tank body 2 is raised by the lifting frame 1, the gravitational potential energy of the sugarcane juice flowing out through the juice inlet pipe 4 increases, thereby increasing the flow velocity of the sugarcane juice within the tank body 2, thus accelerating the flow speed of the sugarcane juice within the tank body 2. After falling onto the juice inlet tray 5, the sugarcane juice is dispersed, and the sugarcane juice dispersed by the juice inlet tray 5 falls onto the aeration plate 6 for further dispersion, and then flows in multiple streams towards the outlet pipe 23 through the aeration holes 611, and is finally discharged through the outlet pipe 23. In the aforementioned process, the area of the sugarcane juice in contact with air within the tank body 2 is greatly increased. It can be seen that this utility model can improve the aeration efficiency by accelerating the flow speed of the sugarcane juice and the area of contact with air.
[0023] In this embodiment, the barrel 2 includes an upper barrel 21 and a flow guide ring plate 22. The flow guide ring plate 22 is connected to the bottom of the upper barrel 21. The inner side of the flow guide ring plate 22 forms a 25-degree angle with the horizontal cross-section of the upper barrel 21. Specifically, the angle between the inner side of the flow guide ring plate 22 and the horizontal cross-section of the upper barrel 21 is α, and the angle α is 25°. The exhaust pipe 3 is installed on the top of the upper barrel 21 away from the flow guide ring plate 22. The outflow pipe 23 is installed on the bottom of the flow guide ring plate 22 away from the upper barrel 21. After passing through the aeration hole 611, the sugarcane juice flows in multiple streams to the flow guide ring plate 22, and is guided by the flow guide ring plate 22 to the outflow pipe 23. The arrangement of the flow guide ring plate 22 facilitates the collection and discharge of the sugarcane juice.
[0024] In this embodiment, the center line of the end of the juice inlet pipe 4 used for juice discharge coincides with the center line of the upper barrel 21, so that the end of the juice inlet pipe 4 used for juice discharge is located at the upper center of the upper barrel 21, so as to ensure that the sugarcane juice flows evenly from the periphery of the juice inlet tray 5 after falling onto the juice inlet tray 5.
[0025] In this embodiment, the air diffuser plate 6 includes an arc-shaped plate 61 and a connecting ring plate 62. The connecting ring plate 62 connects to the periphery of the arc-shaped plate 61 and to the inner side of the barrel body 2. The arc-shaped plate 61 convexes towards the exhaust pipe 3, so that the sugarcane juice flows downhill towards the connecting ring plate 62 after falling onto the arc-shaped plate 61. The air diffuser holes 611 are evenly distributed on the arc-shaped plate 61. Compared with a flat plate, the arc-shaped plate 61 can increase the contact area between the sugarcane juice and the air while guiding the flow of the sugarcane juice.
[0026] In this embodiment, the connecting ring plate 62 is provided with a juice leakage hole 621. After the sugarcane juice flows onto the connecting ring plate 62, it continues to flow down through the juice leakage hole 621, preventing the sugarcane juice from accumulating at the connecting ring plate 62.
[0027] In this embodiment, a spiral groove 63 is recessed on the arc-shaped plate 61, and the spiral groove 63 extends spirally outward from the inside of the arc-shaped plate 61 toward the inner side of the barrel 2. The spiral groove 63 can guide some of the sugarcane juice falling into the tank in a spiral manner, and can further increase the contact area between the sugarcane juice and the air.
[0028] After aeration treatment of the sugarcane juice using the aeration tank in this embodiment, the purity of the mixed juice increases by 0.5 GP. According to the sugar production report, based on a sugarcane crushing volume of 900,000 tons, for every 1 GP increase in the purity of the mixed juice, the sugar yield increases by 0.13%. Therefore, an increase of 0.5 GP in purity can result in an additional 168 tons of white sugar production.
[0029] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
