Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cheese production, in particular to a spraying type disinfection device for cheese production. BACKGROUND

[0002] The fermentation tank is the core equipment in the cheese production process, and its cleanliness directly affects the product quality. During use, the fermentation tank is easily contaminated by external microorganisms, and the substances produced during the fermentation process can cause corrosion and wear to the inner wall and components of the fermentation tank. If not cleaned and disinfected in time, these substances will gradually accumulate, increasing the degree of corrosion and wear of the equipment and shortening the service life of the equipment.

[0003] To solve this problem, the Chinese patent document with publication number CN118976766A discloses a tank wall cleaning device for fermentation tank production, which includes a mobile trolley and a fermentation tank body. The mobile trolley is provided with a liquid storage mechanism for storing cleaning medium, a lifting mechanism for lifting movement, and a liquid supply mechanism for delivering cleaning medium. The lifting mechanism is provided with a blowing mechanism for providing high-pressure air and a rotating mechanism for rotating cleaning. When disinfecting the fermentation tank, the rotating mechanism sprays disinfectant into the inner wall of the fermentation tank to disinfect the inner wall of the fermentation tank.

[0004] However, during the spraying process of the disinfectant, the medicament solution adhering to the inner wall of the tank body will naturally flow and fall due to the influence of gravity. When the surface tension of the disinfectant is lower than the critical surface tension of the tank wall material, liquid droplet flowing will be triggered, causing the medicament to form an uneven liquid film, instead of gathering and forming a liquid stream flowing down. This phenomenon not only significantly reduces the coverage rate of the tank wall surface, forming a medicament coverage blind area and breeding microbial contamination hazards, but also causes excessive accumulation of disinfectant at the tank bottom and insufficient effective concentration in the upper area, ultimately resulting in poor overall disinfection effect. Therefore, we propose a spraying type disinfection device for cheese production. SUMMARY

[0005] One technical problem to be solved by the present application is that during the spraying process of the disinfectant, the medicament solution adhering to the inner wall of the tank body will naturally flow and fall due to the influence of gravity, which will significantly reduce the coverage rate of the tank wall surface, form a medicament coverage blind area and breed microbial contamination hazards, and cause excessive accumulation of disinfectant at the tank bottom and insufficient effective concentration in the upper area, ultimately resulting in poor overall disinfection effect.

[0017] 1. Tangential air flow formed by the air deflector quickly blows away disinfectant droplets adhering to the inner wall of the tank. In the traditional spraying disinfection process, disinfectant droplets often gather and flow downward due to gravity, forming a "flowing hanging" phenomenon, which not only leads to excessive accumulation of disinfectant in local areas of the tank, causing uneven disinfection, but also avoids the risk of microbial growth caused by flowing hanging, greatly improving the health and safety level of the tank.

[0018] 2. The arrangement of the flow guide optimizes the direction of the air flow, allowing the liquid film formed by the disinfectant on the inner wall of the tank to spread evenly. In the traditional disinfection method, uneven distribution of the liquid film is a common problem. The local accumulation of disinfectant leads to excessive concentration, which not only causes waste but also may cause corrosion of the tank material. In other areas, the disinfectant is insufficient to achieve effective disinfection. The device guides the flow of the liquid film through the flow guide block, ensuring that the disinfectant forms a liquid film with uniform thickness on the inner wall of the tank, greatly reducing the risk of local liquid accumulation and improving the utilization rate of disinfectant, making the disinfection process more efficient.

[0035] The spray disinfection unit 6 comprises a spraying part 7 arranged on the rotating frame 2, which sprays disinfectant into the inner wall of the tank body 1, a driving part 8 is arranged on the rotating frame 2, which drives the plurality of stirring plates 3 to expand synchronously.

[0036] The spraying part 7 comprises a plurality of sliding grooves 71 arranged on the rotating frame 2, a plurality of arc-shaped plates 72 are slidingly arranged in the sliding grooves 71 respectively, the arc-shaped plates 72 are circumferentially spliced to form a closed ring structure, a plurality of mounting rods 73 are arranged on the arc-shaped plates 72, the mounting rods 73 are connected with the stirring plates 3, a liquid storage cavity 74 is arranged in the stirring plate 3, the liquid storage cavity 74 is connected with the nozzles 5, a liquid guide pipe 75 is arranged on the liquid storage cavity 74, the liquid guide pipe 75 is connected with a disinfectant supply device, a driving motor is arranged outside the tank body 1, and the power output end of the driving motor is connected with the rotating frame 2.

[0037] The driving part 8 comprises a rotating shaft 81 rotatingly arranged on the rotating frame 2, one end of the rotating shaft 81 located in the rotating frame 2 is connected with a power motor, a driving screw 82 is arranged on the rotating shaft 81, a first positioning seat 83 and a second positioning seat 84 are arranged on the rotating shaft 81 and the driving screw 82 respectively, the second positioning seat 84 is threadedly connected with the driving screw 82, a sliding groove 85 is arranged on the arc-shaped plate 72, a first fixing seat 86 is arranged on the arc-shaped plate 72, a second fixing seat 87 is slidingly arranged in the sliding groove 85, a first connecting rod 88 is rotatingly arranged on the first positioning seat 83 and the second fixing seat 87, a second connecting rod 89 is rotatingly arranged on the second positioning seat 84 and the first fixing seat 86, and the first connecting rod 88 and the second connecting rod 89 are rotatingly connected.

[0038] After the initial cleaning of the fermentation tank is completed, the staff first drives the rotating shaft 81 to rotate by starting the power motor, and the rotating shaft 81 drives the driving lead screw 82 provided thereon to rotate at the same time, and drives the positioning seat two 84 connected therewith to move while the lead screw rotates, and synchronously cooperates with the connecting rod one 88 and the connecting rod two 89 to drive the arc-shaped plate 72 to move, so that the plurality of arc-shaped plates 72 in the closed ring structure are separated, and the stirring plate 3 connected with the arc-shaped plate 72 is synchronously driven to move, thereby driving the stirring plate 3 to be close to the inner wall of the tank body 1, and synchronously driving the nozzle 5 connected with the stirring plate 3 to be close to the inner wall of the tank body 1. This design ensures that the disinfectant can be directly and efficiently sprayed to each area of the inner wall of the tank body 1, avoiding the uneven spraying or omission problem that may exist in the traditional disinfection method, greatly improving the coverage and accuracy of disinfection.

[0039] After completion, the disinfectant is supplied to the liquid storage cavity 74 through the external disinfectant supply device, and then the disinfectant is sprayed to the inner wall of the tank body 1 through the nozzle 5, and the rotating frame 2 is synchronously rotated when the disinfectant is sprayed, so as to improve the uniformity of the disinfectant spraying. At the same time, since the nozzle 5 can be positioned and close to the inner wall of the tank body 1, the disinfectant can act more directly on the target surface during the spraying process, reducing the splashing and waste of disinfectant caused by too far spraying distance or improper angle. This not only reduces the disinfection cost, but also improves the utilization rate of disinfectant, so that each drop of disinfectant can play the maximum disinfection effect, and after disinfection is completed, the rotating shaft 81 can be controlled to rotate in the reverse direction to control the plurality of arc-shaped plates 72 to return to the closed ring structure again, so that the disinfection device does not affect the normal fermentation of the tank body 1.

[0040] The air curtain unit 9 includes an extending piece 10 provided on the stirring plate 3, which drives the air deflector 4 to extend from the stirring plate 3, the stirring plate 3 is provided with a power piece 11, which provides power for the work of the extending piece 10, the stirring plate 3 is provided with a deflection piece 12, which drives the air deflector 4 extending from the stirring plate 3 to deflect, and the air deflector 4 is provided with a flow guide piece 13 to guide the airflow.

[0041] The extending piece 10 includes a plurality of accommodation grooves 101 opened on the stirring plate 3, the accommodation grooves 101 are slidably connected with the air deflector 4, a moving groove 102 connected with the accommodation groove 101 is opened in the stirring plate 3, an extending pipe 103 is provided on the air deflector 4, the extending pipe 103 is movably connected with the moving groove 102, a connecting rod 104 is provided in the extending pipe 103, the connecting rod 104 is connected with the extending pipe 103 through a damping rotating shaft, a rotating lead screw 105 is rotatably provided in the stirring plate 3, and the rotating lead screw 105 is threadedly connected with the connecting rod 104.

[0042] The power element 11 comprises a power groove 111 opened on the stirring plate 3, and one end of a rotating screw rod 105 extends into the power groove 111, and a synchronous worm wheel 112 is arranged at one end of the rotating screw rod 105 in the power groove 111, and a synchronous worm 113 engaged with the synchronous worm wheel 112 is arranged in the power groove 111. A clockwork box 114 is arranged in the power groove 111, and the clockwork box 114 is rotationally connected with the synchronous worm 113, and a clockwork spring 115 is arranged in the clockwork box 114, and one end of the clockwork spring 115 is connected with the synchronous worm 113, and a winding shaft 116 is arranged on the synchronous worm 113, and a protection tube 117 is arranged on the stirring plate 3, and the protection tube 117 is located between the arc-shaped plate 72 and the stirring plate 3, and a traction rope 118 is arranged on the winding shaft 116, and the traction rope 118 passes through the protection tube 117 and is connected with the rotating shaft 81, and the traction rope 118 is made of nylon.

[0043] When the arc-shaped plate 72 is moved to be unfolded, since one end of the traction rope 118 is connected with the rotating shaft 81, the traction rope 118 is stretched, thereby driving the winding shaft 116 to rotate, and the winding shaft 116 drives the synchronous worm 113 connected therewith to rotate when rotating, and the synchronous worm 113 drives the plurality of synchronous worm wheels 112 engaged therewith to rotate, and at this time, the clockwork spring 115 is in a force storage state, and the synchronous worm wheels 112 drive the rotating screw rod 105 to rotate, and the rotating screw rod 105 drives the connecting rod 104 to rotate, and since the connecting rod 104 is connected with the extension tube 103 through the damping rotating shaft, and the extension tube 103 is in a limiting state, the extension tube 103 and the connecting rod 104 are moved when the rotating screw rod 105 rotates, thereby driving the air deflector 4 to extend from the containing groove 101, and when the arc-shaped plate 72 is reset, the clockwork spring 115 releases the stored force to re-wind the traction rope 118, and simultaneously drives the air deflector 4 to reset, and in the process of moving and unfolding the arc-shaped plate 72, the automatic extension of the air deflector 4 is realized through the linkage mechanism of the traction rope 118, the winding shaft 116, the synchronous worm 113, the synchronous worm wheels 112 and the rotating screw rod 105, and this process does not need manual intervention, thereby improving the automation degree of operation and reducing the possibility of human error, and the clockwork spring 115 stores force in the process of extending the air deflector 4, and releases energy when resetting, thereby realizing the recycling and reuse of energy, and this design reduces the dependence of the device on external energy and reduces energy consumption.

[0044] The deflection element 12 comprises a guide groove 121 opened on the extension tube 103, the extension tube 103 is provided with a spiral groove 122, and the spiral groove 122 is communicated with the guide groove 121, and the moving groove 102 is provided with a guide rod 123, and the guide rod 123 extends into the spiral groove 122 and the guide groove 121 and is slidably connected with the spiral groove 122 and the guide groove 121.

[0045] The guide member 13 comprises a guide groove 131 formed on the air deflector 4, the air deflector 4 is provided with an air inlet 132 in communication with the guide groove 131, the top surface of the air deflector 4 is provided with a plurality of air outlets 133, and the air outlets 133 are provided with guide blocks 134.

[0046] When the extension pipe 103 moves, when the air deflector 4 is not completely extended from the accommodation groove 101, the guide rod 123 located in the moving groove 102 slides with the guide groove 121 to limit the extension pipe 103, so as to ensure that the extension pipe 103 and the air deflector 4 can be smoothly extended from the accommodation groove 101, when the air deflector 4 is extended from the accommodation groove 101, the guide rod 123 is separated from the guide groove 121 and contacts the spiral groove 122, and the air deflector 4 is deflected under the pushing of the spiral groove 122, the sliding fit of the guide rod 123 and the guide groove 121 ensures that the air deflector 4 maintains a straight trajectory during the extension process, prevents position deviation, and improves the action reliability, after the air deflector 4 is deflected, the windward surface thereof forms an included angle with the airflow direction, which effectively reduces the resistance of direct impact of the airflow, not only reduces the energy consumption of the device, but also improves the utilization efficiency of the airflow, so that more airflow can be used to form an air curtain, and the inclined air deflector 4 makes the airflow more easily enter the guide groove 131 from the air inlet 132 and form a laminar flow through the guidance of the guide block 134, which effectively improves the uniformity of the air curtain and ensures that each area of the inner wall of the tank body 1 can be affected by uniform airflow, thereby improving the disinfection effect.

[0047] The above design optimizes the airflow direction, solves the problem of disinfectant concentration difference caused by uneven distribution of liquid film in the traditional disinfection method, guides the airflow through the guide block 134 to blow the disinfectant, so that the liquid film formed by the disinfectant on the inner wall of the tank body 1 is uniform in thickness, ensuring the stability of the disinfectant concentration in each area, thereby realizing comprehensive and consistent disinfection effect, and the uniformly spread liquid film can cover every corner of the inner wall of the tank body 1, including the curved surfaces and gaps that are difficult to reach in the traditional disinfection method, which greatly improves the disinfection effect and effectively reduces the risk of microbial residue, and the guide rod 123 and the spiral groove 122 accurately adjust the deflection angle of the air deflector 4, so that the airflow can penetrate into every corner and complex curved surface area of the tank body 1, in the traditional jet disinfection, due to the complex shape of the tank body 1, there are often jet blind areas, which cannot be effectively disinfected, becoming a potential health hazard, and the unique air deflector 4 design and deflection angle adjustment mechanism of the device completely eliminates the jet blind area, ensuring that every part of the inner wall of the tank body 1 can be fully disinfected, providing a safer and healthier environment for cheese production.

[0048] And because the liquid film is evenly distributed, it avoids the excessive use of disinfectant caused by local accumulation of liquid, and also prevents waste caused by insufficient disinfectant in other areas. This dosage control significantly improves the utilization rate of disinfectant, reduces production costs, and the evenly distributed disinfectant reduces the risk of corrosion of the tank body 1 material in local high-concentration areas, prolonging the service life of the tank body 1. This not only reduces downtime and maintenance costs caused by tank body 1 damage, but also improves the overall stability of the production line.

[0049] At the same time, after completing the disinfection, the uniform airflow also helps to speed up the drying process of the disinfectant on the inner wall of the tank body 1, which not only shortens the disinfection cycle and improves production efficiency, but also reduces the amount of subsequent cleaning work caused by disinfectant residue.

[0050] Example 2: Please refer to Figure 13 The present application provides a technical solution: the air deflector 4 is provided with a control device 14, the control device 14 includes a control pipe 141 arranged in a guide groove 131, the control pipe 141 is connected with an air inlet 132, the control pipe 141 is provided with a control groove 142, the control pipe 141 is slidably provided with a sliding plate 143, the sliding plate 143 is provided with a return spring 144 away from the air inlet 132, one end of the return spring 144 is connected with the control pipe 141. In actual disinfection operation, different types of disinfectant have different viscosity characteristics due to their different compositions. High-viscosity disinfectant is prone to form a thick liquid film when spreading on the inner wall of the tank body 1. When using high-viscosity disinfectant, the air inlet can be significantly increased by simultaneously increasing the control groove 142 on the control pipe 141. This design allows the air deflector 4 to generate stronger airflow lift at the same speed, effectively overcoming the resistance of high-viscosity liquid film and ensuring uniform spreading of disinfectant. For low-viscosity disinfectant, the control groove 142 opening can be appropriately reduced to avoid liquid film splashing caused by excessive airflow, achieving accurate control of the disinfection process. By increasing the control groove 142, the airflow lift can be significantly improved without increasing the speed of the air deflector 4 or only slightly adjusting the speed. This design effectively reduces the energy consumption of the air deflector 4 when rotating, reduces the motor load, and prolongs the service life of the equipment.
