Description

Technical Field

[0001] This utility model relates to the field of carbonation reaction technology, and in particular to a continuous carbonation reaction tower for rice wine. Background Technology

[0002] A continuous carbonation reaction tower for rice wine is a specialized piece of equipment for carbonation in rice wine processing. The rice wine flows from top to bottom, and the carbon dioxide is evenly dispersed through the gas distribution structure and then comes into countercurrent contact to continuously complete the dissolved gas reaction. It can precisely control the temperature, pressure and carbon dioxide concentration to ensure uniform carbonation of rice wine, is suitable for large-scale production, improves processing efficiency and reduces flavor loss.

[0003] The continuous carbonation reaction tower for rice wine first cools, filters, and removes impurities from the rice wine. Food-grade carbon dioxide is then vaporized and pressurized before being continuously fed into the tower from the top and bottom, respectively. Inside the tower, packing or a microporous distributor allows for counter-current gas-liquid contact. The carbon dioxide dissolves into the rice wine under high pressure and low temperature. Stable pressure and residence time within the tower ensure complete dissolution. Finally, the carbonated rice wine is discharged from the bottom of the tower, and undissolved carbon dioxide is recovered and reused, enabling continuous production. However, when the continuous reaction tower reaches a steady state, changes in the flow rate, temperature, purity of the rice wine, or the pressure and flow rate of the carbon dioxide can lead to unstable reaction conditions within the tower, thus affecting the carbonation effect and product quality. Existing technologies employ intermittent operation to address this issue. Continuous feeding is paused to clear unstable materials from the tower. Then, pre-treated rice wine that meets standards is added in batches, along with carbon dioxide at stable pressure and flow rates. Reaction parameters are precisely controlled within the closed tower. Once a single batch of carbonation meets the standards and is discharged, the continuous system parameters are recalibrated to ensure stable resumption of subsequent continuous production. However, existing intermittent carbonation reactions require frequent start-up and shutdown of the equipment for material addition and discharge. This method not only consumes a significant amount of time but also leads to product quality fluctuations due to operational errors. Furthermore, the carbon dioxide reaction within the equipment cannot remain constant after restarting, affecting the uniformity and completeness of the carbonation reaction. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a continuous carbonation reaction tower for rice wine, which aims to improve the problems of frequent shutdowns, long processing times, large quality fluctuations, and unstable, uneven, and insufficient carbon dioxide reaction conditions when restarting the intermittent carbonation reaction equipment in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a continuous carbonation reaction tower for rice wine, comprising a reaction tank, a uniformizing mechanism fixedly connected to the bottom of the reaction tank for uniformly spraying carbon dioxide gas, and a quick-replacement mechanism fixedly connected to the right side of the reaction tank for quickly replacing the rice wine feed pipe and preventing gas leakage; the uniformizing mechanism includes an air pump, the top of which is installed at the bottom of the reaction tank, the output end of which is fixedly connected to a buffer chamber, the top of which is fixedly connected to a gas guide pipe, a limit ring fixedly connected to the top outer wall of the gas guide pipe, and a gas outlet assembly slidably connected to the outer wall of the limit ring.

[0006] As a further description of the above technical solution: The air outlet assembly includes an air storage chamber, the inner wall of which is rotatably connected to the outer wall of a limiting ring. Multiple moving columns are fixedly connected at equal intervals to the outer wall of the air storage chamber, and multiple air outlets are fixedly connected at equal intervals to the outer walls of the moving columns.

[0007] As a further description of the above technical solution: The quick-change mechanism includes an inflow pipe, the left side of which is fixedly connected to the right side of the outer wall of the reaction vessel. Multiple limiting blocks are fixedly connected to the right side of the inner wall of the inflow pipe, and a plug is fixedly connected to the right side of the limiting blocks. A locking component is installed on the right side of the plug.

[0008] As a further description of the above technical solution: The locking assembly includes a grooved tube, the left side of which is fixedly connected to the right side of the outer wall of the inflow tube. A push-out spring is fixedly connected to the middle of the grooved tube, and a moving ring is fixedly connected to the other end of the push-out spring. A locking head is slidably connected inside the moving ring, and multiple steel balls are slidably connected to the left side of the outer wall of the locking head.

[0009] As a further description of the above technical solution: A wine flow pipe is installed on the right side of the reaction vessel, and the outer left side of the wine flow pipe is threaded to the inner right side of the locking head.

[0010] As a further description of the above technical solution: The top of the reaction vessel is bolted to a top cover, and a pressure gauge is fixedly connected to the middle of the top cover.

[0011] As a further description of the above technical solution: A support ring is fixedly connected to the bottom of the outer wall of the reaction vessel, and multiple support columns are fixedly connected at equal intervals to the bottom of the support ring.

[0012] As a further description of the above technical solution: An air inlet pipe is connected to the right side of the air pump, and a carbon dioxide tank is connected to the right side of the air inlet pipe.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the gas pump draws in gas and sends it into the buffer chamber. Then, high-pressure carbon dioxide enters the gas outlet component through the gas guide pipe. The rotation of the gas outlet component causes the carbon dioxide to rise evenly at the bottom of the reaction tank. Combined with the gas stabilizing effect of the buffer chamber, the carbon dioxide is released stably and evenly and integrated into the rice wine. This solves the problems of frequent start-up and shutdown, long time consumption, large quality fluctuations, and unstable, uneven, and insufficient reaction conditions after restarting of intermittent carbonation reaction equipment.

[0014] 2. In this utility model, after the locking component is locked, as the locking head is inserted, the locking head will push up the plug, releasing the blockage of the inflow pipe. When the locking head is removed, the spring on the limit block pushes up the plug, re-blocking the inflow pipe, thereby preventing gas from flowing out of the reaction vessel and thus avoiding the problem of slow packing efficiency.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a continuous carbonation reaction tower for rice wine, comprising a reaction tank 1. A uniformizing mechanism 2 is fixedly connected to the bottom of the reaction tank 1, used to uniformly spray carbon dioxide gas. A quick-change mechanism 3 is fixedly connected to the right side of the reaction tank 1, used to quickly replace the rice wine feed pipe and prevent gas leakage. The uniformizing mechanism 2 includes a gas pump 201, which is a vortex gas pump. Its working principle is that the motor drives the impeller to rotate, and the blades push the gas to make circular motion in the vortex cavity, generating centrifugal force to pressurize the gas, which is then discharged from the exhaust port and continuously drawn in through the inlet. It consists of a motor, impeller, pump body, inlet and exhaust ports, and a silencer. The top of the gas pump 201 is installed at the bottom of the reaction tank 1. The output end of the air pump 201 is fixedly connected to a buffer chamber 202. The top of the buffer chamber 202 is fixedly connected to a guide pipe 203. The carbon dioxide gas drawn in by the air pump 201 enters the guide pipe 203 under the buffer of the buffer chamber 202. The top outer wall of the guide pipe 203 is fixedly connected to a limiting ring 204. The outer wall of the limiting ring 204 is slidably connected to an air outlet assembly 205. The limiting ring 204 is used to prevent the air outlet assembly 205 from detaching. The air outlet assembly 205 includes an air storage chamber 2051. The inner wall of the air storage chamber 2051 is rotatably connected to the outer wall of the limiting ring 204. Multiple moving columns 2052 are fixedly connected at equal intervals to the outer wall of the air storage chamber 2051. Multiple air outlets 2053 are fixedly connected at equal intervals to the outer wall of each moving column 2052. Specifically, firstly, the air pump 201 starts, drawing carbon dioxide gas from the carbon dioxide tank 10 and delivering it to the buffer chamber 202. The high-pressure carbon dioxide enters the buffer chamber 202, where it disperses significantly, reducing the instantaneous pressure. The buffered carbon dioxide then flows out of the buffer chamber 202 at a stable pressure and enters the storage chamber 2051 through the air guide pipe 203. The high-pressure carbon dioxide accumulates in the storage chamber 2051, causing it to rise slightly. A fixed limiting ring 204 physically constrains the storage chamber 2051, preventing it from deviating from its preset track due to air pressure, ensuring stable component connection. Then, the carbon dioxide gas in the storage chamber 2051 moves through its surroundings... The gas column 2052 is finally ejected at high speed from the gas outlet 2053 at the end. As the gas is ejected, a reaction force is generated, which drives the entire gas outlet assembly 205 to rotate around the central axis. During the rotation, the gas outlet 2053 will spray carbon dioxide from different angles to the bottom of the reaction tank 1, so that the gas can diffuse upward evenly and fully contact and mix with the rice wine. The middle buffer chamber 202 and the gas outlet assembly 205 work together to ensure that the carbon dioxide is released stably, continuously and evenly and mixed into the rice wine. This design fundamentally solves the problems of long time consumption, large quality fluctuations caused by frequent shutdowns of intermittent carbonation reaction equipment, as well as the unstable carbon dioxide reaction conditions and insufficient mixing when restarting. It ensures the continuity of the rice wine carbonation process and the consistency of product quality.

[0019] Reference Figure 4 and Figure 5 The quick-change mechanism 3 includes an inflow pipe 301. The left side of the inflow pipe 301 is fixedly connected to the right side of the outer wall of the reaction vessel 1. Multiple limiting blocks 302 are fixedly connected to the right side of the inner wall of the inflow pipe 301. A plug 303 is fixedly connected to the right side of each limiting block 302. The plug 303 is used to prevent gas leakage. The limiting blocks 302 support the plug 303 to block the inflow pipe 301. A locking assembly 304 is installed on the right side of the plug 303. The locking assembly 304 includes a grooved tube 3041. The left side of the grooved tube 3041... A side-fixed connection is made to the right side of the outer wall of the inflow pipe 301. A push-out spring 3042 is fixedly connected to the middle of the grooved pipe 3041. A moving ring 3043 is fixedly connected to the other end of the push-out spring 3042. A locking head 3044 is slidably connected inside the moving ring 3043. Multiple steel balls 3045 are slidably connected to the left side of the outer wall of the locking head 3044. A wine flow pipe 4 is installed on the right side of the reaction tank 1. The left side of the outer wall of the wine flow pipe 4 is threadedly connected to the right side of the inner wall of the locking head 3044. The wine flow pipe 4 is used for the inflow of the rice wine raw liquid. Specifically, first, the locking head 3044 is aligned and fixed to the outlet end of the wine flow pipe 4. Then, the moving ring 3043 is pulled to release its constraint on the steel ball 3045. After the locking head 3044 is inserted into the grooved pipe 3041, the moving ring 3043 is released. At this time, the ejector spring 3042 fixed at the rear end of the moving ring 3043 releases its elastic potential energy, pushing the moving ring 3043 to reset. The reset moving ring 3043 pushes the steel ball 3045 through its internal inclined surface, causing the steel ball 3045 to move towards the center of the grooved pipe 3041 and finally lock into the groove on the outer wall of the locking head 3044. This achieves rapid fixing of the wine flow pipe 4 to the storage tank, ensuring a stable connection and preventing it from falling off. During the insertion of the locking head 3044, its front end pushes the plug 303, causing the plug 303 to overcome its initial limit and move upward, thereby releasing the flow into the pipe. The sealing of pipe 301 allows the rice wine to flow smoothly from the wine flow pipe 4 through the inlet pipe 301 into the new storage tank. When it is necessary to remove the locking head 3044 to replace the storage tank, the moving ring 3043 is pulled again to disengage the steel ball 3045 from the groove of the locking head 3044, and the locking head 3044 can be pulled out. At this time, the spring fixed on the limit block 302 will push the plug 303 to reset, re-sealing the inlet of the inlet pipe 301 to prevent the residual carbon dioxide gas inside the reaction tank 1 from leaking from the inlet pipe 301. Through the design of automatic unlocking and automatic sealing of the plug when inserted and removed, the storage tank can be quickly connected and fixed, and the pressure drop caused by gas leakage in the reaction tank 1 can be avoided. This structure solves the gas leakage problem at its source, indirectly ensuring the efficiency of the filling and avoiding the increase in filling time caused by frequent pressure replenishment.

[0020] Reference Figure 1 and Figure 2 The top of the reaction vessel 1 is bolted to a top cover 5, and a pressure gauge 6 is fixedly connected to the middle of the top cover 5. A support ring 7 is fixedly connected to the bottom of the outer wall of the reaction vessel 1, and multiple support columns 8 are fixedly connected at equal intervals to the bottom of the support ring 7. An air inlet pipe 9 is connected to the right side of the air pump 201, and a carbon dioxide tank 10 is connected to the right side of the air inlet pipe 9. Specifically, the reaction vessel 1 is supported by multiple support columns 8 via a bottom support ring 7. Then, the uniform mechanism 2 is activated to draw carbon dioxide gas from the carbon dioxide tank 10. The gas is delivered into the reaction vessel 1 through the gas inlet pipe 9. Throughout the reaction process, the pressure gauge 6 fixed on the top cover 5 of the reaction vessel 1 continuously plays a role in monitoring the changes in gas pressure inside the vessel in real time and clearly displaying the pressure value on the dial. Based on the reading of the pressure gauge 6, the operator can promptly determine whether the pressure inside the vessel is within the reasonable range required for the reaction, thereby avoiding instability of the reaction due to abnormal pressure and ultimately achieving the goal of stable operation of the reaction vessel 1.

[0021] Working principle: As the air pump 201 draws carbon dioxide from the carbon dioxide tank 10 and sends it into the buffer chamber 202, the high-pressure buffered carbon dioxide enters the buffer chamber 202 and disperses within it, reducing gas pressure and stabilizing the gas. Subsequently, the carbon dioxide gas, under high pressure, enters the storage chamber 2051 from the buffer chamber 202 through the gas guide pipe 203. The high-pressure carbon dioxide gas enters the storage chamber 2051 and then pushes it up. The storage chamber 2051 is prevented from falling out by the limiting ring 204. Then, the carbon dioxide gas flows into the storage chamber 2051, which is connected to the surrounding area. Inside the moving column 2052, carbon dioxide gas is ejected from the outlet 2053. As the carbon dioxide gas is ejected from the outlet 2053, it drives the entire outlet assembly 205 to rotate. Because the rotation of the outlet assembly 205 causes the carbon dioxide to move evenly at the bottom of the reaction tank 1, and the buffer chamber 202 slows down and stabilizes the carbon dioxide gas, thus achieving a stable and uniform release of carbon dioxide and its integration into the rice wine. This solves the problem of unstable, uneven and insufficient carbon dioxide reaction conditions when restarting intermittent carbonation reaction equipment after frequent shutdowns, long time consumption and large quality fluctuations. When replacing a rice wine storage tank, fix the locking head 3044 to the outlet end of its liquid output pipe. Then pull the moving ring 3043 to release the limit on the steel ball 3045. As the locking head 3044 is inserted, it releases the moving ring 3043. The ejector spring 3042 fixed to the moving ring 3043 pushes up the moving ring 3043. The steel ball 3045 is then pushed and fixed inside the moving ring 3043. As the steel ball 3045 fixed inside the grooved tube 3041 locks into the groove of the locking head 3044, it... To achieve rapid fixation, when the locking head 3044 is inserted, it pushes up the plug 303, thereby releasing the fixation of the inflow pipe 301. When the locking head 3044 is removed, the spring fixed on the limit block 302 pushes up the plug 303, causing the plug 303 to re-block the inflow pipe 301. With the inflow pipe 301 blocked, the problem of preventing gas from flowing out of the reaction vessel 1 is solved, thereby preventing the problem of slow packing efficiency.
