Description

Technical Field

[0001] This utility model belongs to the technical field of winemaking, and more specifically, it relates to a device for adding liquid additives. Background Technology

[0002] In grape processing, after destemming and crushing, the pulp and juice are directly exposed to air, making them highly susceptible to oxidation. This not only leads to a deterioration in the color and flavor of the grape raw material but can also affect the quality and shelf life of subsequent processed products. Therefore, before pumping the destemmed and crushed grapes into the pneumatic press or directly into the tank, potassium metabisulfite liquid must be added. Its antioxidant properties inhibit oxidation, ensuring the freshness and processing stability of the grape raw material. Currently, the industry commonly uses a manual addition method for this step, where operators pour the potassium metabisulfite solution directly into the grape raw material based on experience or approximate measurement, and then perform initial mixing during the material's transport or stirring. The existing methods of adding additives have the following drawbacks: they are highly random due to human intervention, and the amount and method of addition can vary between different operators and different batches, making it impossible to guarantee the stability of the additive's effect and hindering the unified control of the quality of processed products. Utility Model Content The purpose of this invention is to provide a device for adding liquid additives, which aims to solve the problem of poor stability of artificially added additives in the prior art.

[0003] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a device for adding liquid additives, comprising: frame; A solution preparation tank is located at the bottom of the frame; the interior of the solution preparation tank contains a prepared additive solution. The liquid supply hose, one end of which is located inside the liquid mixing tank; and The pump assembly includes a pump mechanism rotatable about its own axis; the pump mechanism is mounted on the frame and has at least one roller on its edge; the supply hose is wound around the pump mechanism; when the pump mechanism rotates, the roller presses against the supply hose, pumping the additive solution in the dispensing tank out through the supply hose.

[0004] In one possible implementation, the pumping mechanism includes: The rotating shaft is rotatably connected to the frame; The rotating arm is fixedly connected to the rotating shaft; and A roller is rotatably connected to the end of the rotating arm; the liquid supply hose is arranged along the edge trajectory of the rotating arm; when the rotating arm rotates, the roller squeezes the liquid supply hose.

[0005] In one possible implementation, multiple rotating arms are provided and are evenly distributed along the circumference of the rotating axis, with the rotating arms positioned perpendicular to the rotating axis.

[0006] In one possible implementation, the pumping assembly includes: The motor is fixedly connected to the frame; and A transmission mechanism is disposed between the motor and the rotating shaft; the motor drives the rotating shaft to rotate through the transmission mechanism.

[0007] In one possible implementation, the transmission mechanism includes: The drive wheel is fixedly connected to the power output shaft of the motor; Driven wheel, fixedly connected to the rotating shaft; and The transmission component is connected to the driving wheel and the driven wheel.

[0008] In one possible implementation, the side of the liquid preparation tank is provided with a feeding port.

[0009] In one possible implementation, the liquid preparation tank is equipped with a stirring mechanism.

[0010] In one possible implementation, one side of the liquid preparation tank is a transparent viewing panel.

[0011] In one possible implementation, the transparent viewing panel is provided with scale lines.

[0012] The beneficial effects of the liquid additive adding device provided by this utility model are as follows: Compared with the prior art, this liquid additive adding device uses mechanical extrusion to pump out the additive solution, replacing the traditional manual pouring operation and reducing human interference in the adding process. This mechanically driven pumping method can precisely control the pressure of the rollers on the hose and the rotation speed of the pumping mechanism, thereby achieving precise control of the additive solution output, ensuring that the amount added each time is consistent and improving the stability of the additive's effect. At the same time, the efficiency of mechanical pumping is much higher than that of manual addition, which can meet the needs of continuous production in scenarios such as grape processing, improve the efficiency of the overall processing flow, and avoid processing stagnation due to slow addition speed. In addition, the pumping method of rollers pressing the hose does not come into direct contact with the solution, which can effectively prevent the pump components from contaminating the solution, ensuring the purity of the additive solution, and thus ensuring the quality and safety of the subsequently processed products.

[0018] It should be further explained that the accompanying drawings and embodiments of this utility model mainly describe the concept of this utility model. Based on this concept, some specific forms and settings of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, under the premise that those skilled in the art understand the concept of this utility model, they can implement the above-mentioned specific forms and settings in a well-known manner.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0020] In the description of this utility model, "multiple" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0021] The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself; the term "length"... "Width", "Top", "Bottom", "Front", "Back", "Left", "Right", "Vertical" The terms "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of facilitating the description of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the present invention.

[0022] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," and "above" are used here to describe the spatial positional relationship between a device or feature and other devices or features, as shown in the figure. It should be understood that spatial relative terms are intended to... The invention includes different orientations of the device in use or operation, in addition to those described in the figures.

[0023] Reference Figures 1 to 2 The present invention provides a device for adding liquid additives. The device for adding liquid additives includes a frame 1, a liquid mixing tank 2, a liquid supply hose 3, and a pump assembly 4.

[0024] The mixing tank 2 is located at the bottom of the frame 1; the mixing tank 2 contains a prepared additive solution. One end of the supply hose 3 is located inside the mixing tank 2. The pump assembly 4 includes a pump mechanism 43 that can rotate around its own axis; the pump mechanism 43 is mounted on the frame 1 and has at least one roller 433 on its edge; the supply hose 3 is wound around the pump mechanism 43; when the pump mechanism 43 rotates, the roller 433 presses against the supply hose 3, pumping the additive solution in the mixing tank 2 out through the supply hose 3. The bottom inner wall of the mixing tank 2 has a lowest point, forming a funnel shape at the lowest point, and one end of the supply hose 3 is fixed at the lowest point of the mixing tank 2.

[0025] The pumping mechanism 43 in the pumping assembly 4 can rotate around its own axis. When the rollers 433 on the edge rotate, they can press the liquid supply hose 3, pumping out the additive solution in the mixing tank 2 through mechanical extrusion. This replaces the traditional manual pouring operation, eliminates the randomness of human operation, and avoids differences in the amount and method of addition by different operators and different batches. This mechanical pumping method can precisely control the output amount of the additive solution by controlling the rotation speed of the pumping mechanism 43 and the pressing force of the rollers 433, ensuring that the amount added each time is consistent, improving the stability of the additive's effect, and facilitating the unified control of the quality of processed products.

[0026] The rotation of the pumping mechanism 43 and the pressing action of the roller 433 work together to form a continuous and stable pumping force, so that the additive solution can be pumped out and added to the raw materials evenly and continuously, avoiding the problem of local concentration being too high or too low due to concentrated dumping of the solution that may occur when adding manually. The evenly added additive can be more fully mixed with the raw materials and give full play to its due role. For example, in grape processing, antioxidant additives can come into more even contact with the pulp and juice, more effectively inhibiting oxidation reactions and ensuring the freshness of the raw materials and the stability of processing.

[0027] Compared to manual addition, mechanically driven pumping significantly improves the efficiency of additive addition, adapts to the needs of continuous production, avoids processing stagnation caused by slow manual addition, and improves the efficiency of the overall processing flow. At the same time, the simple structure of the pumping component 4 and the liquid supply hose 3 reduces the risk of failure during operation, reduces equipment maintenance costs and downtime, and further ensures the continuity of production.

[0028] The pumping method of the roller 433 pressing the liquid supply hose 3 ensures that the moving parts of the pumping assembly 4 do not come into direct contact with the additive solution, thus avoiding contamination of the solution by the pump body parts. This is especially suitable for additive addition scenarios with high purity requirements. This non-contact pumping structure also facilitates the cleaning and replacement of the liquid supply hose 3, reduces the difficulty of equipment cleaning and maintenance, and ensures that the additive solution added each time is not affected by residual substances in the equipment parts.

[0029] In one possible implementation, the pump suction mechanism 43 includes: a rotating shaft 431, a rotating arm 432, and a roller 433.

[0030] The rotating shaft 431 is rotatably connected to the frame 1. The rotating arm 432 is fixedly connected to the rotating shaft 431. The roller 433 is rotatably connected to the end of the rotating arm 432; the liquid supply hose 3 is set along the edge trajectory of the rotating arm 432; when the rotating arm 432 rotates, the roller 433 squeezes the liquid supply hose 3.

[0031] The rotating shaft 431 is rotatably connected to the frame 1, providing stable rotational support for the entire pump suction mechanism 43 and ensuring that there is no deviation or shaking during rotation. The rotating arm 432 is fixedly connected to the rotating shaft 431 and can rotate synchronously around the axis with the rotation of the rotating shaft 431, forming a transmission path for driving power. The roller 433 is rotatably connected to the end of the rotating arm 432 and can rotate flexibly around its own axis. The liquid supply hose 3 is set along the edge trajectory of the rotating arm 432, so that the hose matches the movement trajectory of the rotating arm 432. When the rotating shaft 431 drives the rotating arm 432 to rotate, the roller 433 at the end of the rotating arm 432 will make a circular motion. During the movement, the roller 433 will continuously squeeze the liquid supply hose 3, changing the internal volume of the hose through the squeezing action, thereby generating negative pressure suction, drawing the additive solution in the liquid tank 2 into the hose. At the same time, with the continuous squeezing of the roller 433, the solution is pushed towards the outlet direction in the hose, ultimately achieving a stable output of the additive solution.

[0032] Mechanical extrusion pumps out the additive solution, replacing manual pouring and reducing human interference. Precise control of the clamping force of the roller 433 on the hose and the rotation speed of the pump mechanism 43 allows for precise regulation of the solution output, ensuring consistent dosage each time and improving the stability of the additive's effect. Mechanical pumping is more efficient than manual pumping, making it suitable for continuous production needs such as grape processing. It improves overall processing efficiency and prevents processing stoppages due to slow addition speeds. Furthermore, the pumping method of the roller 433 clamping the hose avoids direct contact with the solution, preventing pump components from contaminating the solution, ensuring the purity of the additive solution, and thus guaranteeing the quality and safety of subsequently processed products.

[0033] In one possible implementation, multiple rotating arms 432 are provided and are evenly distributed along the circumference of the rotating shaft 431, with the rotating arms 432 positioned perpendicular to the rotating shaft 431.

[0034] Multiple rotating arms 432 are evenly distributed circumferentially around and perpendicular to the rotating shaft 431. This allows each rotating arm 432 to evenly distribute the pumping work during rotation, avoiding excessive wear of components caused by long-term stress on a single rotating arm 432 and extending the service life of the overall structure. The evenly distributed layout ensures that the time intervals between adjacent rotating arms 432 driving the rollers 433 to squeeze the liquid supply hose 3 are consistent, enabling continuous and uniform output of the additive solution, preventing interruptions in solution delivery or flow fluctuations, and ensuring a stable addition process. The perpendicularity of the rotating arms 432 to the rotating shaft 431 allows for a more rational direction of the squeezing force of the rollers 433 on the hose, ensuring uniform and effective squeezing force on the hose and improving solution pumping efficiency. At the same time, this structural layout also optimizes the use of internal space, making the arrangement of components more compact, reducing the overall space occupied by the device, and adapting to the installation requirements of more processing scenarios.

[0035] In one possible implementation, the pump suction assembly 4 includes a motor 41 and a transmission mechanism 42.

[0036] The motor 41 is fixedly connected to the frame 1. The transmission mechanism 42 is located between the motor 41 and the rotating shaft 431; the motor 41 drives the rotating shaft 431 to rotate through the transmission mechanism 42.

[0037] The motor 41 is fixed to the frame 1, providing a stable and continuous power source for the pumping mechanism 43. This avoids the problem of unstable power output when manually driven, ensuring smooth and efficient pumping action. The fixed installation of the motor 41 also reduces vibration during operation, minimizing wear on components and extending the overall service life of the equipment. The transmission mechanism 42 connects the motor 41 and the rotating shaft 431, enabling smooth power transmission and preventing excessive impact caused by the motor 41 directly acting on the rotating shaft 431. This protects the rotating shaft 431 and related components, reducing the probability of malfunctions. The transmission mechanism 42 also allows for flexible adjustment of the rotation speed of the rotating shaft 431, adapting to the output requirements of the additive solution in different processing scenarios and improving the applicability of the device. Furthermore, this power transmission structure facilitates separate maintenance of the motor 41 or the rotating shaft 431, reducing equipment maintenance difficulty and ensuring the continuity of the production process.

[0038] In one possible implementation, the transmission mechanism 42 includes: a driving wheel 421, a driven wheel 422, and a transmission element 423.

[0039] The driving wheel 421 is fixedly connected to the power output shaft of the motor 41. The driven wheel 422 is fixedly connected to the rotating shaft 431. The transmission component 423 is connected to the driving wheel 421 and the driven wheel 422.

[0040] In a preferred embodiment, the driving sprocket 421 is a driving sprocket, fixedly connected to the power output shaft of the motor 41, and rotates synchronously with the rotation of the motor 41 output shaft; the driven sprocket 422 is a driven sprocket, fixedly connected to the rotating shaft 431, and can drive the rotating shaft 431 to rotate together; the transmission component 423 is a chain, which meshes with the driving sprocket and the driven sprocket to form a complete power transmission structure. When the motor 41 starts, the power output shaft drives the driving sprocket to rotate, and the driving sprocket transmits power to the driven sprocket through the meshing chain. The driven sprocket then drives the rotating shaft 431 to rotate, ultimately realizing the operation of the pump suction mechanism 43.

[0041] The meshing transmission of the sprocket and chain offers high transmission precision, accurately controlling the speed ratio between the driving wheel 421 and the driven wheel 422. This ensures that the rotating shaft 431 rotates stably at a preset speed, thereby guaranteeing the accuracy of the additive solution output and preventing fluctuations in the addition amount due to transmission errors. This meshing transmission method boasts high transmission efficiency, effectively reducing power loss and allowing the power of the motor 41 to be more fully converted into the operating power of the pump suction mechanism 43, thus improving the overall operating efficiency of the device. Simultaneously, the sprocket and chain structure has strong load-bearing capacity, adapting to long-term, high-frequency operation requirements and minimizing the risk of damage to transmission components, thus extending the device's service life. Furthermore, the clearance between the chain and sprocket can be compensated for through structural adjustments, facilitating future maintenance, reducing equipment maintenance costs, and ensuring the continuity of the production process.

[0042] In a preferred embodiment, the driving pulley 421 is a driving pulley, fixedly mounted on the power output shaft of the motor 41, and rotates when the motor 41 starts; the driven pulley 422 is a driven pulley, fixedly mounted on the rotating shaft 431, and rotates synchronously with the rotating shaft 431; the transmission component 423 is a transmission belt, which is tensioned and mounted on the driving pulley and the driven pulley, transmitting power through the friction between the belt and the pulley. When the motor 41 is running, the driving pulley rotates, using friction to drive the transmission belt, which in turn drives the driven pulley to rotate through friction, and the driven pulley drives the rotating shaft 431 to rotate, providing operating power for the pump suction mechanism 43.

[0043] Belt drives offer excellent cushioning and shock absorption, absorbing vibrations generated during motor 41 operation and preventing their transmission to the shaft 431 and other components of the pumping mechanism 43. This reduces wear on components caused by vibration and extends their service life. Simultaneously, reduced vibration allows the pumping mechanism 43 to operate more smoothly, further ensuring the stability of the additive solution output. Furthermore, belt drives have a simple structure, are easy to install and disassemble, and require minimal effort to replace the belt or adjust its tension, saving maintenance time. Moreover, belt drives exhibit slippage under overload conditions, effectively protecting core components such as the motor 41 and shaft 431 from overload impacts, preventing damage due to excessive load, and enhancing the safety of the device operation.

[0044] In one possible implementation, the side of the liquid preparation tank 2 is provided with a feeding port 21.

[0045] The feeding port 21 on the side of the mixing tank 2 provides a convenient channel for adding additive raw materials and solvents. Without opening the top of the mixing tank 2 or other enclosed structures, operators can quickly replenish materials directly through the feeding port 21, reducing operational steps and improving mixing efficiency. Especially in continuous production, it can shorten mixing interruption time and ensure the continuity of additive solution supply. The feeding port 21 also facilitates preliminary control of the added raw materials. It can be used in conjunction with auxiliary tools such as measuring cups and funnels to reduce the risk of spillage and material waste. Furthermore, compared to adding from the top of the mixing tank 2, side feeding avoids raw materials splashing onto the outer wall of the tank or other parts of the device, reducing cleaning difficulty, keeping the surrounding environment clean, reducing pollution problems caused by raw material residue, and further ensuring the purity of the additive solution.

[0046] In one possible implementation, the mixing tank 2 is equipped with a stirring mechanism 5.

[0047] The stirring mechanism 5 can be a blade agitator. The stirring mechanism 5 inside the mixing tank 2 continuously stirs the additive solution, breaking up concentration stratification that may occur when the solution is left to stand. This ensures thorough mixing of the additive and solvent, resulting in a uniform concentration throughout the solution and preventing unstable additive effects when added to raw materials due to excessively high or low local concentrations. The operation of the stirring mechanism 5 accelerates the dissolution rate of the additive raw materials in the solvent, especially for difficult-to-dissolve additive components. This reduces the dissolution time, improves mixing efficiency, shortens the solution preparation cycle, and meets the rapid supply requirements of additive solutions for continuous production. Simultaneously, continuous stirring prevents additives from depositing and clumping at the bottom of the mixing tank 2, avoiding blockages in the supply hose 3 or affecting the normal operation of the pump suction assembly 4. This reduces the risk of equipment failure and ensures the stability and continuity of the entire additive system.

[0048] In one possible implementation, one side of the liquid preparation tank 2 is a transparent viewing panel.

[0049] The transparent viewing panel on one side of the mixing tank 2 allows operators to directly observe the remaining amount of additive solution without opening the tank, avoiding contamination due to frequent opening and exposure to air. It also saves time and improves operational convenience. During continuous production, the transparent viewing panel allows real-time monitoring of solution consumption, enabling timely detection of insufficient solution and advance replenishment to prevent interruptions in the addition process due to solution supply disruptions, thus ensuring production continuity. Furthermore, the transparent viewing panel allows operators to observe for abnormal states such as layering, precipitation, or turbidity in the solution. This facilitates timely adjustment or replacement of the solution using the stirring mechanism 5, preventing the addition of substandard additive solutions to raw materials, further ensuring the stability of subsequent processed product quality, and reducing production risks caused by solution abnormalities.

[0050] In one possible implementation, scale lines are provided on the transparent viewing panel.

[0051] The graduated lines on the transparent display panel allow operators to accurately read the remaining amount of additive solution in the mixing tank 2, eliminating reliance on estimation or experience. This prevents insufficient or excessive addition due to errors in solution volume judgment, ensuring that the amount of additive solution added each time meets processing requirements. When preparing the additive solution, the graduated lines serve as a precise measurement reference, helping operators add raw materials and solvents according to preset ratios, ensuring uniform solution concentration and reducing the impact of concentration errors on the additive's effectiveness. Simultaneously, the graduated lines provide a clearer understanding of the solution consumption rate, facilitating advance planning of material replenishment times and preventing sudden supply interruptions during production, ensuring a continuous and stable addition process. The precise display of values ​​also facilitates production records and data traceability, contributing to process optimization and improving overall processing quality control.

[0052] The beneficial effects of the liquid additive adding device provided by this utility model are as follows: Compared with the prior art, the liquid additive adding device of this utility model achieves the pumping out of the additive solution through mechanical extrusion, replacing the traditional manual pouring operation and reducing the interference of human factors on the adding process. This mechanically driven pumping method can precisely control the clamping force of the roller 433 on the hose and the rotation speed of the pumping mechanism 43, thereby achieving precise control of the output amount of the additive solution, ensuring that the amount added each time is consistent, and improving the stability of the additive's effect. At the same time, the efficiency of mechanical pumping is much higher than that of manual addition, which can meet the needs of continuous production in scenarios such as grape processing, improve the efficiency of the overall processing flow, and avoid processing stagnation due to slow addition speed. In addition, the pumping method of the roller 433 clamping the hose does not come into direct contact with the solution, which can effectively prevent the pump body components from contaminating the solution, ensuring the purity of the additive solution, and thus ensuring the quality and safety of the subsequently processed products.
