Abstract
Description
Technical Field
[0001] This utility model relates to a stirrer, and more particularly to a stirring device. Background Technology
[0002] Fruit juice is a liquid product obtained from fruits through physical methods such as pressing, centrifugation, and extraction. In the production of concentrated fruit juice, multiple ingredients need to be added to a mixing device for stirring. Due to the large volume of juice being stirred, a relatively long stirring time is required; otherwise, uneven distribution of pulp and inconsistent juice concentration can easily occur, leading to low stirring efficiency. Therefore, there is an urgent need for a device that can significantly improve stirring efficiency. Utility Model Content
[0003] The purpose of this invention is to provide a stirring device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] The solution to the technical problem of this utility model is:
[0005] A mixing device includes: a tank body with a discharge port on the bottom side; a premixing mechanism including a premixing tank, a feeding cylinder, and an auger, wherein the premixing tank is connected to the top side of the tank body, the feeding cylinder is disposed on the top of the premixing tank, a premixing gap is formed between the feeding cylinder and the top side of the tank body, the auger is rotatably connected to the feeding cylinder, the bottom side of the premixing tank is provided with a plurality of communicating holes communicating with the tank body around the auger, and a plurality of first feed ports are provided on the outer side of the premixing tank; and a mixing mechanism having a mixing paddle that can rotate within the tank body.
[0006] This technical solution has at least the following beneficial effects: Fruit juice raw materials are fed into the feed cylinder, and a rotating auger conveys them downwards into the premixing tank. The rotation of the auger provides rotational power to the fruit juice raw materials, causing them to tend to rotate within the premixing gaps. Multiple first inlets on the outside of the premixing tank can be connected to multiple external flavoring additive input sources, allowing flavoring additives to be added into the premixing tank from these inlets. This premixing process with the fruit juice raw materials within the premixing gaps is efficient. The rotating fruit juice raw materials improve the mixing efficiency with the flavoring additives, enhancing the mixing effect between the fruit juice raw materials and the flavoring additives within the premixing tank. The mixing effect within the tank is achieved by continuously feeding the fruit juice raw materials located in the premixing gaps into the tank body through multiple connecting holes on the bottom side of the premixing tank. These multiple connecting holes increase the coverage area when the fruit juice raw materials are fed into the tank body, allowing premixed fruit juice to be fed into the tank body from multiple locations. Then, the stirring paddle in the stirring mechanism rotates in the tank body to further stir and mix the fruit juice. In this way, the fruit juice and flavoring additives are premixed in the premixing tank before being fed into the stirring and mixing tank body, and then dispersed to multiple connecting holes to feed the premixed fruit juice into the tank body. This effectively shortens the time required to stir the fruit juice evenly and improves the overall production efficiency.
[0007] As a further improvement to the above technical solution, the bottom surface of the premixing tank is a dispersing surface, with the middle part of the dispersing surface arching upwards and facing the feed cylinder. Multiple connecting holes are respectively located on the outer side of the dispersing surface. The fruit juice raw material fed into the premixing tank from the bottom of the feed cylinder flows to the dispersing surface directly opposite it. Because the middle part of the dispersing surface arches upwards, the fruit juice raw material can be diverted to all sides. This enhances the fluidity of the fruit juice raw material rotating around the middle part of the dispersing surface within the premixing gaps, allowing for more thorough premixing with the flavoring additives fed into the multiple first feed ports. Then, the mixture is discharged downwards into the tank body through the multiple connecting holes on the outer side of the dispersing surface.
[0008] As a further improvement to the above technical solution, a fixing frame is connected to the top side of the tank below the dispersion surface, and a guide plate is connected to the bottom side of the fixing frame. Multiple first guide grooves are provided on the top side of the guide plate, and these first guide grooves are arranged radially on the guide plate. The fixing frame provides installation and fixation for the guide plate, so that the guide plate is relatively fixed below the dispersion surface. At this time, the juice raw material discharged downwards from the multiple connecting holes flows onto the guide plate and flows outwards from the multiple first guide grooves on the guide plate to the surrounding area of the tank. The guide plate can guide the transfer of the juice raw material, changing the position where the premixed juice falls into the tank. This allows the premixed juice to be further dispersed to multiple positions inside the tank, deviating from the center, before falling into the tank, effectively improving the problem of concentrated juice mixing and enhancing the mixing effect.
[0009] As a further improvement to the above technical solution, a plurality of guide rods are arranged around the outer side of the guide plate, and a plurality of second guide grooves are respectively provided on the top side of the plurality of guide rods. The plurality of second guide grooves are respectively connected to the plurality of first guide grooves. The plurality of guide rods can further extend the travel distance of the juice on the guide plate. When the premixed juice falls into the guide plate, some juice flows from the first guide groove into the second guide groove on the guide rod, and then falls into the tank. In this way, the guide plate can input the juice into the tank at different radial positions, further dispersing the position of the juice mixed into the tank and improving the mixing effect of the juice.
[0010] As a further improvement to the above technical solution, a support rod is connected to the bottom center of the dispersion surface via the fixing frame. The support rod provides further support to the center of the dispersion surface, thereby enhancing the structural strength of the dispersion surface and effectively preventing deformation due to prolonged impact from the dropping and pressing of the fruit juice raw materials.
[0011] As a further improvement to the above technical solution, a liquid level sensor is installed inside the premixing tank. The liquid level sensor can detect the liquid level inside the premixing tank, thereby preventing the liquid level from being too high or too low, which would affect the premixing effect.
[0012] As a further improvement to the above technical solution, the top of the feeding cylinder protrudes upward from the premixing tank. A first motor is installed at the top of the feeding cylinder, and the first motor is connected to the auger. A second feed port is provided on the outer side of the feeding cylinder. The first motor provides rotational driving force to the auger, which can drive the auger to rotate inside the feeding cylinder. When fruit juice raw materials need to be input, the second feed port on the outer side of the feeding cylinder is connected to an external fruit juice raw material input source. After the fruit juice raw materials are input into the feeding cylinder, they are conveyed downward as the auger rotates, and have rotational power when falling into the premixing gap.
[0013] As a further improvement to the above technical solution, the stirring mechanism includes a second motor connected to the top side of the tank, and the second motor is driven by the stirring paddle. The second motor can provide a rotational driving force to the stirring paddle, causing the stirring paddle to rotate inside the tank, thereby further stirring and mixing the juice inside the tank.
[0014] As a further improvement to the above technical solution, multiple stirring paddles are arranged around the premixing tank inside the tank. These multiple stirring paddles rotate at different positions within the tank, simultaneously stirring and mixing the juice within the tank. This is particularly suitable for stirring and mixing large volumes of juice, improving the uniformity of mixing the juice at different locations.
[0015] As a further improvement to the above technical solution, a scraper is connected to the bottom side of the stirring paddle, and the scraper is inclined from top to bottom in the direction of rotation of the stirring paddle. When the stirring paddle rotates, it can drive the scraper on its bottom side to rotate synchronously. At this time, the inclined scraper can apply an upward pushing force to the material at the bottom of the tank, effectively improving the phenomenon of fruit pulp and other materials accumulating at the bottom of the tank and improving the uniformity of the juice mixing.

[0024] Reference Figure 1 A mixing device includes a tank 100, a premixing mechanism, and a mixing mechanism. The tank 100 has a discharge port 110 on its bottom side. Naturally, a valve is installed at the discharge port 110. When mixing fruit juice, the valve closes the discharge port 110; when discharging the mixed fruit juice, the valve is open. The premixing mechanism includes a premixing tank 210, a feeding cylinder 220, and an auger 230. The premixing tank 210 is connected to the top of the tank 100. On one side, the feed cylinder 220 is disposed on the top of the premixing tank 210, and a premixing gap is formed between the feed cylinder 220 and the top side of the tank body 100. The auger 230 is rotatably connected to the feed cylinder 220. The bottom side of the premixing tank 210 is provided with a plurality of connecting holes 260 communicating with the tank body 100 around the auger 230. A plurality of first feed ports 240 are provided on the outside of the premixing tank 210. The stirring mechanism has a stirring paddle 310 that can rotate inside the tank body 100.
[0025] As described above, the fruit juice raw material is fed into the feed cylinder 220, and the rotating auger 230 conveys it downwards into the premixing tank 210. The rotation of the auger 230 provides rotational power to the fruit juice raw material, causing it to tend to rotate within the premixing gaps. Multiple first inlets 240 on the outside of the premixing tank 210 can be connected to multiple external flavoring additive input sources, allowing flavoring additives to be added into the premixing tank 210 from these inlets. This premixing with the fruit juice raw material within the premixing gaps improves the mixing efficiency with the flavoring additives, enhancing the mixing effect of the fruit juice raw material and flavoring additives within the premixing tank 210. During the process, the fruit juice raw materials located in the premixing gaps are continuously fed into the tank 100 through multiple connecting holes 260 on the bottom side of the premixing tank 210. The multiple connecting holes 260 can increase the coverage area when the fruit juice raw materials are fed into the tank 100, realizing the input of premixed fruit juice into the tank 100 from multiple positions. Then, the stirring paddle 310 in the stirring mechanism rotates in the tank 100 to further stir and mix the fruit juice. In this way, the fruit juice and flavoring additives are premixed in the premixing tank 210 before being fed into the stirring and mixing, and then dispersed into the multiple connecting holes 260 to input the premixed fruit juice into the tank 100. This effectively shortens the time required to stir the fruit juice evenly and improves the overall production efficiency.
[0026] The bottom surface of the premixing tank 210 can be a plane. When the juice raw material is discharged from the discharge cylinder into the premixing gap, the juice raw material has poor fluidity due to the large space of the premixing gap and the lack of continuous rotational flow power. Therefore, in order to improve the mixing efficiency of the juice raw material in the premixing gap, in this embodiment, the bottom surface of the premixing tank 210 is a dispersing surface 211. The middle part of the dispersing surface 211 is arched upward and faces the feed cylinder 220. The multiple connecting holes 260 are respectively arranged on the outer side of the dispersing surface 211. The fruit juice raw material fed into the premixing tank 210 from the bottom of the feed cylinder 220 flows to the dispersion surface 211 directly opposite it. Since the middle of the dispersion surface 211 is arched upward, the fruit juice raw material can be diverted to all sides. At this time, the fluidity of the fruit juice raw material rotating around the middle of the dispersion surface 211 in the premixing gap can be enhanced, and it can be more fully premixed with the flavoring additives fed into the multiple first feed ports 240. Then, it is discharged downward into the tank 100 from the multiple connecting holes 260 on the outside of the dispersion surface 211.
[0027] In the above embodiment, discharging fruit juice raw material into the tank 100 through multiple connecting holes 260 can effectively disperse the position of the raw material mixed into the tank 100. However, limited by the area of the dispersing surface 211, the dispersion position of the connecting holes 260 within the tank 100 is relatively limited. Therefore, in order to further disperse the position of the fruit juice raw material mixed into the tank 100, such as... Figure 2As shown, in this embodiment, a fixing frame 120 is connected to the top side of the tank 100 below the dispersion surface 211, and a guide plate 130 is connected to the bottom side of the fixing frame 120. A plurality of first guide grooves 131 are provided on the top side of the guide plate 130, and the plurality of first guide grooves 131 are arranged radially on the guide plate 130. The mounting bracket 120 can provide installation and fixation for the guide plate 130, so that the guide plate 130 is relatively fixed below the dispersion surface 211. At this time, the juice raw material discharged downward from the multiple connecting holes 260 flows onto the guide plate 130 and flows from the multiple first guide grooves 131 on the guide plate 130 to the periphery of the tank 100. The guide plate 130 can guide the transfer of the juice raw material and change the position of the premixed juice falling into the tank 100. This allows the premixed juice to be further dispersed to multiple positions inside the tank 100 that are off-center before falling into the tank 100, effectively improving the problem of concentrated position when the juice is mixed in and improving the mixing effect of the juice.
[0028] Furthermore, a plurality of guide rods 132 are arranged around the outer side of the guide plate 130, and a plurality of second guide grooves 133 are respectively arranged on the top side of the plurality of guide rods 132. The plurality of second guide grooves 133 are respectively connected to the plurality of first guide grooves 131. In practical applications, the total number of guide rods 132 can be half the total number of first guide grooves 131. In this case, the plurality of guide rods 132 are connected at intervals to the positions of the guide plate 130 corresponding to the outer edges of the plurality of first guide grooves 131. Multiple guide rods 132 can further extend the flow path of the juice on the guide plate 130. When the premixed juice falls into the guide plate 130, some of the juice flows from the first guide groove 131 into the second guide groove 133 on the guide rod 132, and then falls into the tank 100. In this way, the guide plate 130 can input the juice into the tank 100 at different radial positions along the tank 100, further dispersing the position of the juice mixed into the tank 100 and improving the mixing effect of the juice.
[0029] To further strengthen the structural strength of the dispersion surface 211, in this embodiment, a support rod 140 is connected to the bottom center of the dispersion surface 211 via the fixing frame 120. The support rod 140 provides further support to the center of the dispersion surface 211, thereby enhancing its structural strength and effectively preventing deformation due to prolonged impact from the dropping of fruit juice raw materials.
[0030] When the fruit juice raw materials are discharged from the discharge cylinder into the premixing tank 210, some of the fruit juice raw materials will be directly discharged into the tank 100 through multiple connecting holes 260. Therefore, it is necessary to control the rate at which the fruit juice raw materials are fed into the premixing tank 210. This requires ensuring that there is fruit juice raw material premixed with flavoring additives in the premixing gaps, while also preventing the fruit juice raw material level in the premixing tank 210 from becoming too high. To control the rate of fruit juice raw material input in real time, in this embodiment, a liquid level sensor is installed in the premixing tank 210. The liquid level sensor can detect the liquid level in the premixing tank 210, thereby preventing the liquid level in the premixing tank 210 from becoming too high or too low, which would affect the premixing effect.
[0031] The feed cylinder 220 is equipped with a drive source that can drive the auger 230 to rotate. This can be a motor installed on the side wall of the feed cylinder 220, which is connected to the auger 230 to provide power, or a rotary drive source installed at the top of the feed cylinder 220. Specifically, the top of the feed cylinder 220 protrudes upward from the premixing tank 210. A first motor 250 is installed at the top of the feed cylinder 220. The first motor 250 is connected to the auger 230 and can drive the auger 230 to rotate along the vertical axis. A second feed port 270 is provided on the outer side of the feed cylinder 220. The first motor 250 provides rotational driving force to the auger 230, which can drive the auger 230 to rotate inside the feed cylinder 220. When fruit juice raw materials need to be input, the second feed port 270 on the outside of the feed cylinder 220 is connected to the external fruit juice raw material input source. After the fruit juice raw materials are input into the feed cylinder 220, they are conveyed downward as the auger 230 rotates, and have rotational power when falling into the premixing gap.
[0032] The tank 100 is equipped with a drive source that can rotate the stirring paddle 310. Specifically, the stirring mechanism includes a second motor 320 connected to the top side of the tank 100. The second motor 320 is connected to the stirring paddle 310 and can drive the stirring paddle 310 to rotate along its vertical axis. The second motor 320 can provide rotational driving force to the stirring paddle 310, causing the stirring paddle 310 to rotate inside the tank 100, thereby further stirring and mixing the juice inside the tank 100.
[0033] To improve the mixing effect of the stirring paddles 310 within the tank 100, multiple stirring paddles 310 can be used. Specifically, multiple stirring paddles 310 can be arranged around the premixing tank 210 within the tank 100. For example, there can be three stirring paddles 310 arranged in a triangular pattern, or four stirring paddles 310 arranged in a square pattern. The multiple stirring paddles 310 rotating at different positions within the tank 100 can simultaneously mix the fruit juice within the tank 100, which is particularly suitable for mixing large volumes of fruit juice and improving the uniformity of mixing at different locations. In practical applications, the multiple stirring paddles 310 can be driven separately by multiple second motors 320, or simultaneously driven by a single second motor 320.
[0034] Naturally, the stirring paddle 310 itself has stirring blades for stirring and mixing the juice in the tank 100. To further improve the stirring effect of the juice, in this embodiment, a scraper 311 is connected to the bottom side of the stirring paddle 310. The scraper 311 is inclined from top to bottom in the direction of rotation of the stirring paddle 310. When the stirring paddle 310 rotates, it can drive the scraper 311 on its bottom side to rotate synchronously. At this time, the inclined scraper 311 can apply an upward pushing force to the material at the bottom of the tank 100, effectively improving the phenomenon of fruit pulp and other materials accumulating at the bottom of the tank 100 and improving the uniformity of the stirring and mixing of the juice.
