Description

Technical Field

[0001] This invention relates to the field of milk storage technology, and in particular to a device for monitoring the stoppage of the stirring shaft in a milk storage tank. Background Technology

[0002] A milk silo is a stainless steel milk storage device specifically designed for the dairy industry, primarily used for the short-term storage and preservation of fresh milk. To ensure the uniformity of the milk, prevent fat from rising and separating, maintain a uniform temperature, and inhibit microbial growth, the milk in the silo needs to be continuously agitated during storage. If agitation is stopped, the milk may experience problems such as separation, spoilage, and microbial contamination.

[0003] Because the milk hoppers are made of stainless steel, users cannot directly observe the mixing action inside the hopper. Therefore, sensors are needed to monitor the mixing status of the impeller blades inside the hopper. However, some drawbacks have been found when traditional electronic sensors are used in milk hoppers:

[0004] 1. Traditional electronic sensors require openings for installation and come into contact with liquids. Bacteria can easily grow in the probe crevices, increasing the risk of microbial contamination and reducing sensor lifespan due to corrosion, thus increasing replacement costs. Furthermore, milk fat can easily coagulate on the sensor surface, leading to false readings.

[0005] 2. Traditional electronic sensors are expensive, especially in the case of retrofitting old equipment, where the sensors and their associated signal conversion modules will increase the retrofitting costs.

[0006] Therefore, there is an urgent need for a stop monitoring device for the milk tank agitator shaft that has a long service life and low cost. Summary of the Invention

Detailed Implementation

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0047] See Figure 1-3 The milk tank body 1 has a rotating stirring shaft 12 inside, with stirring blades on the stirring shaft 12. The top of the stirring shaft 12 extends from inside the milk tank body 1 and is connected to the drive assembly 11. Specifically, it is driven by a gear, belt, or chain to a reducer or the output shaft of a motor, allowing the stirring shaft 12 to pass through the drive assembly 11. It is worth noting that the milk tank body 1, the drive assembly 11, and the stirring shaft 12 are all prior art, and therefore will not be described in detail.

[0048] A fixed base 2 is fixedly installed on the top of the stirring shaft 12, and an identification flag 24 is fixedly installed on the top of the fixed base 2. An observation tube 3 is fixedly installed on one side of the milk tank body 1 located on the fixed base 2.

[0049] See Figure 3-7 The fixed base 2 is fixedly provided with extension rods 22 around its perimeter. Each extension rod 22 is guided by a movable part 221. The fixed base 2 has an inner cavity 21 in the middle, and multiple counterweights 211 are vertically movable in the inner cavity 21.

[0050] The fixed base 2 has a rope guide frame 23 fixedly installed at the top of the inner cavity 21. The top of each counterweight 211 is connected to a traction rope 231, and the other end of each traction rope 231 is fixedly connected to the movable part 221 after passing through the rope guide frame 23. The rope guide frame 23 can guide the traction rope 231.

[0051] When the stirring shaft 12 rotates, the fixed base 2 also rotates synchronously. At this time, the movable part 221 on the extension rod 22 can move outward by the centrifugal force generated by the rotation. In this way, the movement of the movable part 221 can pull the traction rope 231, thereby pulling the counterweights 211 upward.

[0052] It is worth noting that both the counterweight 211 and the movable part 221 are provided with guide blocks, and the inner cavity 21 and the extension rod 22 are provided with guide grooves corresponding to the guide blocks. Through the matching arrangement between the guide blocks and the guide grooves, the stability of the counterweight 211 and the movable part 221 during the movement can be improved. This is existing technology, so it will not be described in detail.

[0053] See Figure 8-14 The observation tube 3 is fixedly installed on the milk tank body 1 and located on one side of the fixed base 2. The observation tube 3 is provided with a stacking chamber 31, a feeding chamber 32 and a feeding chamber 33 respectively.

[0054] The feeding chamber 33 contains a vertically movable feeding frame 34. The feeding frame 34 has an internal ramp facing the stacking chamber 31. A vertically fixed column 341 is installed inside the feeding frame 34, with the other end of the column 341 extending from the top of the observation tube 3 and fixedly connected to a pull rod handle 342. The pull rod handle 342 allows the user to easily adjust the position of the feeding frame 34.

[0055] Among them, multiple anti-drop columns 332 are fixedly installed on the bottom of the feeding chamber 33 near the unloading chamber 32. The magnetic baffle 343 moves vertically through the anti-drop columns 332, and the bottom of the magnetic baffle 343 is provided with an anti-drop cavity 333 corresponding to the anti-drop columns 332.

[0056] The height of the anti-drop column 332 is greater than the travel distance of the magnetic baffle 343. This not only guides the magnetic baffle 343 through the anti-drop column 332, but also prevents the magnetic baffle 343 from falling off. Furthermore, the anti-drop cavities 333 are all located at the bottom of the magnetic baffle 343, which prevents sand from entering the anti-drop cavities 333 and affecting the movement of the magnetic baffle 343.

[0057] Among them, a stop plate 331 is fixedly installed on the inner wall of the feeding cavity 33 above the magnetic baffle 343. The bottom of the stop plate 331 is made of a magnetic material that is compatible with and attracts the magnetic baffle 343. Friction ridges 344 are provided on the inner wall of the feeding frame 34 and the outer wall of the magnetic baffle 343.

[0058] By setting the friction ridges 344, the friction between the feeding frame 34 and the magnetic baffle 343 can be increased, so as to ensure that the magnetic baffle 343 can move synchronously with the feeding frame 34.

[0059] Users can observe the position of the sand to determine if the stirring shaft 12 has stopped rotating. Both the observation tube 3 and the feeding frame 34 are made of transparent material to facilitate observation of the sand, which is made of a highly visible material such as red.

[0060] See Figure 9 , 15 -21, a through cavity 311 is provided in the observation tube 3 between the accumulation cavity 31 and the discharge cavity 32. The movable plate 4 is located in the through cavity 311 and moves laterally, with one side of the movable plate 4 extending out of the through cavity 311. By opening and closing the movable plate 4 in the through cavity 311, the discharge state of the observation sand in the accumulation cavity 31 can be controlled.

[0061] The observation tube 3 has multiple side plates 35 fixedly installed on both the upper and lower sides of the through cavity 311, and each side plate 35 has a guide post 351 fixedly and vertically installed on it. The movable plate 4 has guide plates 43 fixedly installed on both the upper and lower sides, and the guide plates 43 are guided to move by the guide posts 351. Multiple springs 352 are connected between the side plates 35 and the guide plates 43, and the springs 352 are all located outside the guide posts 351.

[0062] By guiding the guide plate 43 through the guide post 351, not only can the stability of the movable plate 4 be improved during the movement, but the movable plate 4 can also be prevented from falling off.

[0063] The spring 352 allows the movable plate 4 to be pushed outwards, ensuring that it can move outwards even when not being pushed. At this time, the passage cavity 311 is opened, and the observation sand in the accumulation cavity 31 can automatically fall into the discharge cavity 32 by gravity.

[0064] The movable plate 4 has a push cavity 41, and wedge plates 42 are fixedly installed on both sides of the push cavity 41. When the movable component 221 rotates via the stirring shaft 12, the movable component 221 rotates into the push cavity 41 to overcome the elastic force exerted by the spring 352 on the movable plate 4, and pushes the movable plate 4 into the through cavity 311 through the push cavity 41. It is worth noting that the elastic force of the spring 352 is relatively small, and it can only push the movable plate 4 outward when the movable component 221 is not pushing it.

[0065] In this embodiment, the driving component 11 drives the stirring shaft 12 to rotate, thereby stirring the milk in the milk tank body 1. A fixing base 2 is fixedly installed on the top of the stirring shaft 12, and a rigid identification flag 24 is fixedly installed on the top of the fixing base 2. When the stirring shaft 12 rotates, it can drive the fixing base 2 and the identification flag 24 to rotate synchronously. Therefore, the user can know the real-time stirring status of the stirring shaft 12 in the milk tank body 1 by observing the identification flag 24.

[0066] Furthermore, it was observed that the sand initially accumulated within the feeding frame 34. When the drive assembly 11 drove the stirring shaft 12 to rotate, the fixed seat 2 on the stirring shaft 12 also rotated synchronously. During the rotation of the fixed seat 2, the movable parts 221 on the outer side of the fixed seat 2 moved outwards due to the centrifugal force generated during rotation. Furthermore, during the outward movement of the movable parts 221, they could lift the counterweight 211 upwards via the traction rope 231.

[0067] When the movable member 221 is fully moved to the outer side, the rotation of multiple movable members 221 around the stirring shaft 12 pushes the wedge plate 42 on the movable plate 4, thereby pushing the movable plate 4 into the through cavity 311. At this time, the push cavity 41 on the movable plate 4 is aligned with the extended movable member 221, and the rotating movable member 221 can pass through the push cavity 41 to achieve stable pushing of the movable plate 4. In this application, four movable members 221 are provided. No matter what angle the four movable members 221 rotate to, at least one movable member 221 can always be located in the push cavity 41 to push the movable plate 4. In this way, the movable plate 4 can be stably pushed into the through cavity 311 to block the through cavity 311 and thus prevent the observation sand from passing through the through cavity 311.

[0068] It is worth noting that the elastic force of spring 352 is relatively weak, which allows movable part 221 to easily overcome the elastic force of spring 352 and push movable plate 4 to ensure the stability of movable plate 4 when it is locked in through cavity 311. Furthermore, the width of movable plate 4 is greater than the width of through cavity 311, which means that even if movable plate 4 becomes slightly loose in extreme cases, it can still block the bottom of through cavity 311 to prevent sand from falling in.

[0069] Therefore, when the stirring shaft 12 rotates, the movable plate 4 can automatically block the passage cavity 311. At this time, the user only needs to lift the pull rod handle 342 upward, and the pull rod handle 342 can drive the column 341 and the feeding frame 34 to move upward synchronously.

[0070] The feeding frame 34 has a feeding ramp inside, and a magnetic baffle 343 is installed on one side of the feeding frame 34. The magnetic baffle 343 moves synchronously with the feeding frame 34 through the friction of the friction ridges 344. When the feeding frame 34 moves upward, the magnetic baffle 343 also moves upward synchronously due to the friction. This prevents the observation sand inside the feeding frame 34 from falling into the discharging chamber 32 when the feeding frame 34 passes through it.

[0071] As the feeding frame 34 passes through the unloading cavity 32, the magnetic baffle 343 also moves synchronously to the bottom of the stop plate 331. At this point, the stop plate 331 prevents the magnetic baffle 343 from moving further upwards. Furthermore, the feeding frame 34 and the magnetic baffle 343 are not rigidly connected, but move synchronously through friction. Therefore, as the feeding frame 34 continues to move upwards, the magnetic baffle 343 is blocked by the stop plate 331 and cannot continue moving upwards. Additionally, the bottom of the stop plate 331 and the magnetic baffle 343 are attracted by magnetic force, so the magnetic baffle 343 can be adsorbed onto the bottom of the stop plate 331, thus blocking the unloading cavity 32.

[0072] As the feeding frame 34 continues to move upward, the stop plate 331 replaces the magnetic baffle 343 and is located on one side of the feeding frame 34, which prevents the observation sand inside the feeding frame 34 from falling due to the obstruction of the stop plate 331.

[0073] When the feeding frame 34 moves to the top, it connects with the accumulation cavity 31. At this time, the observation sand in the feeding frame 34 can automatically fall into the accumulation cavity 31 by gravity. However, because the connecting cavity 311 is blocked by the movable plate 4, the observation sand in the accumulation cavity 31 cannot fall.

[0074] Finally, the user only needs to release the lever handle 342, and the feeding frame 34 will automatically fall under gravity, so that the feeding frame 34 returns to the bottom of the feeding chamber 33. Furthermore, when the feeding frame 34 passes the side of the magnetic baffle 343, the large frictional force provided by the frictional protrusions 344 between the feeding frame 34 and the magnetic baffle 343 can drive the magnetic baffle 343 to move synchronously downwards to the bottom, releasing the mutual attraction between the magnetic baffle 343 and the stop plate 331, thus achieving synchronous reset of the magnetic baffle 343.

[0075] Furthermore, when the stirring shaft 12 stops rotating, the movable part 221 cannot move outward by centrifugal force. At this time, the counterweight 211 can fall automatically by gravity. In this way, the movable part 221 can be pulled inward by the counterweight 211 through the traction rope 231 to achieve the reset of the movable part 221.

[0076] At this point, the movable part 221 no longer passes through the push cavity 41. The movable plate 4 can then be pushed outward by the elastic force of the spring 352, thereby relieving the blockage of the passage cavity 311 by the movable plate 4. The sand can then pass through the passage cavity 311 and fall into the discharge cavity 32. Finally, the sand is reset to the loading frame 34 through the discharge cavity 32.

[0077] Therefore, as soon as the stirring shaft 12 stops rotating, the sand will automatically fall back into the feeding frame 34. This allows the user to determine whether the stirring shaft 12 has stopped stirring simply by checking whether there is sand accumulating in the feeding frame 34.

[0078] Furthermore, the cavity 311 is equipped with a sealing mechanism, as is common in the prior art, to prevent the observation sand from leaking out of the observation tube 3. The top and bottom of the feeding cavity 33 are respectively equipped with a sand inlet channel and a sand outlet channel, as is common in the prior art, to facilitate the periodic replacement of the observation sand. Additionally, the bottom of the feeding cavity 33 is equipped with a maintenance chamber, ensuring that even if a small amount of observation sand leaks out during the movement of the feeding frame 34, it will only leak into the maintenance chamber, where the user can easily remove it during maintenance. These are all prior art features and will not be elaborated upon further.

[0079] Furthermore, when the stirring shaft 12 starts stirring, the movable plate 4 automatically engages in the through cavity 311. At this time, the user only needs to lift the lever handle 342 upwards to the top to transfer the observation sand in the feeding frame 34 to the accumulation cavity 31. Then, the user can release the lever handle 342 to reset the feeding frame 34.

[0080] As the stirring shaft 12 rotates, the indicator flag 24 will rotate synchronously. Therefore, users only need to check whether the indicator flag 24 is rotating to know the real-time rotation status of the stirring shaft 12.

[0081] However, users cannot continuously observe the rotation status of the indicator flag 24. Therefore, once the stirring shaft 12 stops rotating, the movable plate 4 can automatically move outward by the elastic force of the spring 352, at which point the observation sand can automatically fall back into the feeding frame 34. This allows users to determine whether the stirring shaft 12 has stopped rotating during the stirring process simply by checking whether observation sand has accumulated in the feeding frame 34. If a stoppage occurs, troubleshooting of the drive assembly 11, stirring shaft 12, and related components is required.

[0082] Furthermore, the entire device is installed on the outside of the milk tank body 1. This not only facilitates user observation of the device, but also prevents it from coming into contact with the liquid, thus avoiding the risk of microbial contamination. In addition, this device has strong environmental adaptability and is not easily affected by corrosion, high temperatures, or electromagnetic interference like traditional electronic sensors, ensuring its accuracy and service life.

[0083] Furthermore, traditional Hall effect sensors cost over 800 yuan each, and require signal conversion modules costing several thousand yuan to be used. Installation involves drilling, wiring, sealing, and PLC program modifications, making the process cumbersome. This is especially true in retrofitting older equipment, where electrical cabinets need to be modified to add compatible I / O modules. This results in traditional electronic sensors being cumbersome to install and expensive.

[0084] This device contains no consumables such as batteries or chips; all parts are common metal components or stamped parts. Especially when purchasing in bulk, the cost of a single unit can be reduced to below 300 yuan. Furthermore, the entire device is installed on the outside of the milk tank body 1, requiring only bolts for installation. This device is relatively independent and does not conflict with the control systems of older equipment, making installation very convenient. Moreover, this device does not come into contact with liquids, requires less frequent maintenance, and has a longer service life.

[0085] Therefore, this device monitors the stirring state of the stirring shaft 12 through a purely mechanical structure, without the need for traditional sensors. This not only saves costs but also avoids the effects of corrosion, high temperature or electromagnetic interference, ensuring its adaptability to the environment.

[0086] In this invention, the stirring shaft 12 can be driven to stir inside the milk tank body 1 by the driving component 11. The user can know whether the stirring shaft 12 has stopped rotating by observing the indicator flag 24 and the observation tube 3, so as to realize continuous monitoring of the stirring shaft 12. This device does not come into direct contact with the liquid to prevent the risk of microbial contamination and ensure service life. Moreover, this device is inexpensive and is especially suitable for the renovation of old equipment.

[0087] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
