Description

Technical Field

[0001] This utility model belongs to the field of steam sterilization technology, and specifically relates to a steam sterilization mechanism for a cleaning machine. Background Technology

[0002] In the food processing industry, the cleanliness requirements for food raw materials are stringent. Steam cleaners, as an important cleaning equipment, play a key role in this field. Steam cleaners, also known as saturated steam cleaners, work by using the high temperature and high pressure of saturated steam to clean the dirt attached to the surface of food and promote the vaporization and evaporation of the dirt, thereby achieving the cleaning of food raw materials. Therefore, they are often used in the food industry for cleaning food raw materials.

[0003] However, when using existing steam cleaners to perform steam cleaning operations on food raw materials, the most common method is direct steam injection. This method can only clean a single surface of the food raw material, resulting in a relatively narrow cleaning coverage area. In order to ensure that all surfaces of the food raw material are effectively cleaned, workers often need to manually turn the food raw material multiple times. This operation not only increases manpower input but also significantly prolongs the cleaning operation time, ultimately leading to low cleaning efficiency and failing to meet the demand for high-efficiency cleaning operations in the food processing industry.

[0004] To address the aforementioned issue of low cleaning efficiency, relevant technical fields have conducted improvement research. Among them, Chinese patent publication number "CN221269096U" discloses a steam sterilization cleaning machine. This device optimizes traditional steam cleaning machines to a certain extent. Its structure mainly includes a steam cleaning machine body, with a steam generator fixedly installed at the upper end of the body. A T-shaped connecting pipe is fixedly connected to the exhaust end of the steam generator, extending downwards into the interior of the steam cleaning machine body. Simultaneously, a booster pump is fixedly connected to the inner wall of the steam cleaning machine body, with the T-shaped connecting pipe fixedly connected to the inlet end of the booster pump. The exhaust end is fixedly connected to a jet disc, and there are two booster pumps and two jet discs, symmetrically distributed on the left and right ends of the steam generator. In addition, the main body of the steam cleaner is also fixedly connected to a support plate and an ultraviolet germicidal lamp. There are two support plates, which are distributed vertically and are fixedly installed inside the main body of the steam cleaner. The two support plates are rotatably connected to a rotating shaft. The steam sterilization and cleaning machine disclosed in this patent, through the symmetrical arrangement of booster pumps and jet discs and the rotatable support plate structure, facilitates steam cleaning of multiple surfaces of food raw materials, which improves cleaning efficiency to a certain extent and is a significant improvement over traditional steam cleaners.

[0005] However, in-depth analysis reveals that the steam sterilization and cleaning machine disclosed in the aforementioned patent still has shortcomings that need improvement in practical applications. From a structural layout perspective, the jet discs of this device are only located on both sides of the material frame. During use, the steam can only sterilize the food ingredients on both sides of the material frame, and cannot quickly transport and discharge the steam to the bottom of the material frame and various positions on the outside of the material frame. This results in certain steam discharge dead zones during the overall steam sterilization process. The food ingredients in these dead zone areas cannot be adequately covered by steam, so the overall steam sterilization effect does not reach the ideal state, and there is still considerable room for improvement. Therefore, further improvements to the structure of this device are needed to solve the problem of steam discharge dead zones and improve the steam sterilization effect. Utility Model Content

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A steam sterilization mechanism for a cleaning machine includes a base, a support frame fixedly installed on the top of the base, a sterilization box fixedly installed on the top of the support frame, a storage mechanism movably installed inside the sterilization box, a steam generating mechanism fixedly installed on one side of the sterilization box, a steam exhaust mechanism provided at the lower end of the sterilization box, the output end of the steam generating mechanism and the input end of the steam exhaust mechanism being connected, and the steam generating mechanism being located outside the storage mechanism.

[0009] The storage mechanism includes a fixing plate, which is fixedly installed on the upper middle part of the back of the sterilization box. An electric push rod is fixedly installed on the bottom of the fixing plate. A connecting rod is fixedly installed through the output end of the electric push rod. A hanger is fixedly installed on the outer end of the connecting rod. A sealing cover is fixedly installed on the bottom of the hanger. A placement module is provided at the bottom of the sealing cover. The placement module is located inside the sterilization box and inside the steam generating mechanism.

[0010] As a preferred technical solution, the placement module includes an installation rail, which is fixedly installed on both sides of the bottom of the sealing cover. An installation block is inserted inside the installation rail, and a storage basket is fixedly installed at the bottom of the installation block. The storage basket is located inside the steam generating mechanism.

[0011] As a preferred technical solution, the steam generating mechanism includes a fixed frame, which is fixedly installed in the middle of one side of the sterilization box. A water tank is fixedly installed on the outside of the fixed frame, and heating wires are fixedly installed in a linear arrangement at equal intervals at the bottom of the water tank.

[0012] As a preferred technical solution, a water inlet valve is fixedly installed on one side of the top of the water tank, and a water inlet pipe is fixedly installed at the input end of the water inlet valve.

[0013] As a preferred technical solution, a controller is fixedly installed on the upper front of the sterilization box. The controller has an isosceles trapezoidal side shape, and the control keyboard and display screen of the controller are both located on the inclined surface of the controller.

[0014] As a preferred technical solution, the steam emission mechanism includes a rotary joint and a drive module. The drive module is fixedly installed in the middle of the bottom of the sterilization chamber. The rotary joint is rotatably connected to the middle of the lower end inside the sterilization chamber. The drive module and the rotary joint are meshed together. Steam pipes are fixedly installed in a ring at equal intervals on the top output end of the rotary joint. Steam emission nozzles are fixedly connected in a linear arrangement at equal intervals on the inner side of the steam pipes. The steam emission pipes are located on the outside of the storage basket. The input end of the rotary joint is connected to the top output end of the water tank through a connecting pipe.

[0015] As a preferred technical solution, the drive module includes a fixed arm and a gear ring. The fixed arm is fixedly installed on one side of the bottom of the sterilization box. A drive motor is fixedly installed at the bottom of the fixed arm. A gear is fixedly installed through the fixed arm at the output end of the drive motor. The gear ring is fixedly installed on the bottom outer surface of the rotary joint. The gear ring and the gear are meshed together.

[0016] In summary, the present invention has the following main advantages:

[0017] Firstly, during the application of this technical solution, by setting up a storage mechanism and a steam emission mechanism, the storage basket can be automatically moved and quickly disassembled during use, eliminating the need for operators to manually handle the raw materials to be sterilized. At the same time, the steam emission mechanism can drive the steam pipe to rotate, evenly delivering steam to the surface of the raw materials, covering multiple sides of the raw materials without the need for manual turning, thereby reducing labor input and shortening operation time. This solves the problem of low cleaning efficiency caused by the limited cleaning coverage of traditional steam cleaners in the prior art, which requires multiple manual operations to complete the cleaning of multiple sides of the raw materials. In addition, the electric push rod of the storage mechanism and the rotation design of the steam emission mechanism work together to further improve the continuity of equipment operation, ensuring a stable and orderly cleaning and sterilization process, and avoiding the impact of improper manual operation on the cleaning effect of the raw materials.

[0018] Secondly, during the application of this technical solution, by setting up a steam generating mechanism and a rotatable steam emission mechanism, the saturated steam generated by the steam generating mechanism can fully cover the surrounding and bottom areas of the storage basket through the rotating parts of the steam emission mechanism. At the same time, the steam generating mechanism is located outside the storage mechanism, which can further expand the coverage of the steam and avoid the steam being concentrated in a specific area. This achieves the effect of eliminating dead zones in steam emission, solving the problem that some existing steam cleaning equipment can only perform steam sterilization on the sides of the material frame and cannot deliver steam to the bottom and outside of the material frame, resulting in some areas of the raw material not being in contact with steam and the sterilization effect being insufficient. The synergistic effect of each mechanism can also ensure the stability of the steam concentration in the sterilization box, further improving the uniformity and reliability of raw material sterilization.

[0027] Example

[0028] refer to Figures 1 to 7 The steam sterilization mechanism of a cleaning machine according to this embodiment includes a base 1, a support frame 2 fixedly installed on the top of the base 1, a sterilization box 3 fixedly installed on the top of the support frame 2, a storage mechanism 4 movably installed inside the sterilization box 3, a steam generating mechanism 5 fixedly installed on one side of the sterilization box 3, a steam discharge mechanism 6 provided at the lower end of the sterilization box 3, the output end of the steam generating mechanism 5 and the input end of the steam discharge mechanism 6 are connected, and the steam generating mechanism 5 is located outside the storage mechanism 4;

[0029] The storage mechanism 4 includes a fixing plate 41, which is fixedly installed on the upper middle part of the back of the sterilization chamber 3. An electric push rod 42 is fixedly installed on the bottom of the fixing plate 41. A connecting rod 43 is fixedly installed through the output end of the electric push rod 42. A hanger 44 is fixedly installed on the outer end of the connecting rod 43. A sealing cover 45 is fixedly installed on the bottom of the hanger 44. A placement module 46 is provided at the bottom of the sealing cover 45. The placement module 46 is located inside the sterilization chamber 3 and is located at the steam generating mechanism 5. Inside the device, during application, it is equipped with a base 1, support frame 2, sterilization chamber 3, storage mechanism 4, steam generating mechanism 5, and steam exhaust mechanism 6. This allows the food raw materials to be sterilized to be placed in the placement module 46 of the storage mechanism 4. Then, the electric push rod 42 of the storage mechanism 4 is activated, driving the connecting rod 43 to move. The connecting rod 43 then drives the hanger 44 and sealing cover 45 to move synchronously, causing the placement module 46 to move together with the sealing cover 45 inside the sterilization chamber 3. After the placement module 46 reaches the appropriate position, the steam generating mechanism 5 starts to generate steam. The generated steam is delivered to the input end of the steam emission mechanism 6 through its output end. Then, the steam emission mechanism 6, located at the lower end of the sterilization chamber 3, applies the steam to the food raw materials in the placement module 46 to achieve steam sterilization of the raw materials. Throughout the process, the base 1 provides stable support for the support frame 2, which in turn supports the sterilization chamber 3, ensuring that the sterilization chamber 3 remains stable during equipment operation. The electric push rod 42 of the storage mechanism 4 can flexibly adjust the position of the placement module 46, facilitating the placement of raw materials and position adjustment during the sterilization process. The interconnected design of the steam generating mechanism 5 and the steam emission mechanism 6 ensures stable steam delivery, allowing the steam to act efficiently on the raw materials. The sealing cover 45 works in conjunction with the sterilization chamber 3 during the sterilization process to reduce steam loss and improve the steam sterilization effect. The overall structure makes the device operate smoothly when steam sterilizing food raw materials, effectively completing the sterilization operation and meeting the cleanliness and sterilization requirements of food raw materials.

[0030] refer to Figures 1-5The placement module 46 includes mounting rails 461, which are fixedly installed on both sides of the bottom of the sealing cover 45. Mounting blocks 462 are inserted inside the mounting rails 461, and storage baskets 463 are fixedly installed at the bottom of the mounting blocks 462. The storage baskets 463 are located inside the steam generating mechanism 5. The steam generating mechanism 5 includes a fixing frame 51, which is fixedly installed in the middle of one side of the sterilization chamber 3. A water tank 52 is fixedly installed on the outside of the fixing frame 51. Heating wires 53 are fixedly installed at equal intervals in a linear arrangement inside the bottom of the water tank 52. A water inlet valve 54 is fixedly installed on one side of the top of the water tank 52. The input end of the water inlet valve 54 is fixedly installed... The sterilization chamber 3 is equipped with a water inlet pipe 55 and a controller 7 is fixedly installed on the upper front side. The controller 7 has an isosceles trapezoidal side shape, and its control keyboard and display screen are located on the sloping side. During operation, the device, through the placement module 46, steam generator 5, and controller 7, allows water to be added to the water tank 52 via the water inlet pipe 55. The water inlet valve 54 controls the amount of water added, preventing overflow or insufficient water from affecting subsequent steam generation. When the heating wires 53 arranged linearly at equal intervals at the bottom of the water tank 52 are working, they ensure that the water in the tank 52 is heated evenly, thereby stably generating steam for sterilization. The module 46 generates steam for sterilization. When in use, the mounting block 462 is inserted into the mounting rail 461 to fix the storage basket 463 to the bottom of the sealing cover 45, facilitating the placement of items to be sterilized into the storage basket 463. Operation settings are then configured via the control keyboard of the controller 7. The display screen on the inclined surface of the controller 7 clearly shows the operating parameters and equipment status, allowing operators to easily view and adjust. This controls the electric push rod 42 to move the connecting rod 43, the hanger 44, and the sealing cover 45, causing the storage basket 463 to enter the sterilization chamber 3. The steam generated by the steam generating mechanism 5 acts on the items inside the storage basket 463 to achieve sterilization. This design makes loading and unloading the storage basket 463 more convenient. The cooperation between the mounting block 462 and the mounting rail 461 does not require too much time for fixing or disassembling. The keyboard and display screen on the isosceles trapezoidal side and inclined surface of the controller 7 conform to the user's usage habits. The user can easily operate and view information without having to adjust the viewing angle. The evenly spaced arrangement of the heating wires 53 ensures the uniformity of heating of the water tank 52 and avoids unstable steam generation caused by insufficient local water heating. The water inlet valve 54 can accurately control the water volume and ensure the continuity of steam generation. The overall use process is smoother, which not only improves the convenience of operation, but also ensures the stability and reliability of the sterilization process.

[0031] refer to Figures 4-6The steam emission mechanism 6 includes a rotary joint 61 and a drive module 62. The drive module 62 is fixedly installed at the bottom center of the sterilization chamber 3. The rotary joint 61 is rotatably connected to the lower center of the sterilization chamber 3. The drive module 62 and the rotary joint 61 are meshed together. Steam pipes 63 are fixedly installed in a ring at equal intervals on the top output end of the rotary joint 61. Steam emission nozzles 64 are fixedly connected in a linear arrangement at equal intervals on the inner side of the steam pipes 63. The steam emission pipes are located on the outside of the storage basket 463. The input end of the rotary joint 61 is connected to the top output end of the water tank 52 through a connecting pipe. The drive module 62 includes... The device includes a fixed arm 621 and a gear ring 622. The fixed arm 621 is fixedly installed on one side of the bottom of the sterilization chamber 3. A drive motor 623 is fixedly installed at the bottom of the fixed arm 621. A gear 624 is fixedly installed through the fixed arm 621 at the output end of the drive motor 623. The gear ring 622 is fixedly installed on the bottom outer surface of the rotary joint 61. The gear ring 622 and the gear 624 are meshed together. During the application of this device, the outer sides of the gear ring 622 and the gear 624 are covered with a shell to prevent the gear ring 622 and the gear 624 from being exposed. The device is equipped with a steam emission mechanism 6 and a drive module 62 to ensure that the gear ring 622 and the gear 624 can be used in a controlled manner. The steam is directionally transported and evenly sprayed. The steam generated in the water tank 52 is transported to the input end of the rotary joint 61 through the connecting pipe. After receiving the steam, the rotary joint 61 transmits it to the steam exhaust pipe 63 at the top. The steam exhaust pipe 63 then discharges the steam through the steam exhaust nozzle 64 on the inner side. When the drive module 62 is working, the drive motor 623 will start, and its output end will drive the gear 624 to rotate. The gear 624 meshes with the gear ring 622, causing the gear ring 622 to rotate synchronously with the gear 624, thereby driving the rotary joint 61 to rotate inside the sterilization box 3. During the rotation of the rotary joint 61, the steam exhaust pipe 63 will also be moved. As the steam exhaust nozzles 64 move, they continuously spray steam along with the steam exhaust pipes 63. Since the steam exhaust pipes 63 are arranged in a ring at equal intervals and the steam exhaust nozzles 64 are arranged linearly at equal intervals on the inner side of the pipes, the steam can fully cover the outer area of ​​the storage basket 463, allowing all parts of the items to be sterilized to come into contact with the steam, thus improving the uniformity of sterilization. At the same time, the stable operation of the drive module 62 ensures that the rotary joint 61 rotates smoothly, avoiding interruptions or partial omissions in steam spraying, and ensuring the continuous effectiveness of sterilization. Comprehensive sterilization can be achieved without additional manual adjustment of the steam spray direction, reducing operation steps while improving sterilization efficiency.

[0032] Operating principle and advantages: Before using the equipment, the operator needs to prepare the raw materials and water supply. First, a certain amount of clean water is injected into the water tank 52 through the water inlet pipe 55. The water inlet pipe 55 is used to transport clean water, and the water inlet valve 54 can control the opening and closing of the water inlet pipe 55 to prevent the water tank 52 from overflowing due to excessive water or being too dry, which would affect steam generation. The fixing frame 51 can provide stable support for the water tank 52 to prevent the water tank 52 from shifting due to vibration during equipment operation. Then, the food raw materials to be sterilized are placed in the storage basket 463. The mounting block 462 at the top of the 63 is inserted into the mounting rails 461 on both sides of the bottom of the sealing cover 45. The mounting rails 461 provide positioning and installation foundation for the mounting block 462, which facilitates the quick assembly and disassembly of the storage basket 463 and reduces the time cost of loading and unloading raw materials. The hanger 44 is used to connect the sealing cover 45 and the connecting rod 43 to ensure that the sealing cover 45 moves stably with the connecting rod 43. The electric push rod 42 is fixed to the bottom of the fixing plate 41. The fixing plate 41 can provide fixed support for the electric push rod 42 to ensure that the electric push rod 42 will not shift its position during operation.

[0033] After the preparation is completed, the electric push rod 42 is started by the controller 7. The control keyboard and display screen of the controller 7 are set on the slope, which is in line with the operator's normal operating perspective, making it convenient to view the equipment operating parameters and input operation commands in real time. When the electric push rod 42 is working, its output end drives the connecting rod 43, the hanger 44 and the sealing cover 45 to move down synchronously until the storage basket 463 is completely inside the sterilization box 3 and is inside the steam generating mechanism 5. At this time, the sealing cover 45 is in contact with the top of the sterilization box 3, which can reduce the leakage of steam from the top of the sterilization box 3 during the sterilization process and ensure the stable steam concentration inside the sterilization box 3.

[0034] Once the storage basket 463 is in place, the controller 7 activates the heating wires 53 in the water tank 52 and the drive module 62. The heating wires 53 are linearly arranged at equal intervals and fixed to the bottom of the water tank 52, which can evenly heat the water in the water tank 52, allowing the water to quickly reach its boiling point and vaporize to produce saturated steam. The output end of the steam generating mechanism 5 is connected to the input end of the steam emission mechanism 6, which can deliver the generated saturated steam to the rotary joint 61 of the steam emission mechanism 6. The fixed arm 621 in the drive module 62 can provide fixed support for the drive motor 623. When the drive motor 623 is working, its output end passes through the fixed arm 621 and drives the gear 624 to rotate. The gear 624 meshes with the gear ring 622 on the outer surface of the bottom of the rotary joint 61. The gear ring 622 can engage the gear. The rotational motion of 624 is transmitted to the rotary joint 61, causing the rotary joint 61 to rotate stably in the lower middle part of the sterilization chamber 3. The rotary joint 61 can continuously receive the steam delivered by the steam generating mechanism 5 during the rotation, and at the same time drive the steam exhaust pipe 63 at the top to rotate synchronously. The steam exhaust pipe 63 can evenly distribute the steam to each steam exhaust nozzle 64. The steam exhaust nozzle 64 can spray the steam at a suitable angle and range onto the surface of the food raw materials in the storage basket 463. Since the steam exhaust pipe 63 rotates continuously with the rotary joint 61, the steam can cover the surrounding area and bottom area of ​​the storage basket 463. At the same time, the steam generating mechanism 5 is set on the outside of the storage mechanism 4, further expanding the coverage of the steam and ensuring that all surfaces of the food raw materials can come into contact with high-temperature steam.

[0035] When the sterilization process reaches the set time, the controller 7 shuts off the heating wire 53 and the drive motor 623. The heating wire 53 stops heating and thus stops generating steam, and the drive motor 623 stops working, causing the gear 624, ring gear 622, and rotary joint 61 to stop rotating. Then, the electric push rod 42 is activated, causing its output end to move the connecting rod 43, hanger 44, and sealing cover 45 upwards simultaneously. The storage basket 463 moves upwards and out of the sterilization chamber 3. The operator removes the mounting block 462 from the mounting rail 461, allowing the storage basket 463 to be removed and the sterilized food ingredients taken out, completing the entire sterilization process. Throughout the entire process, this device uses the electric push rod 42 of the storage mechanism 4 to automatically move the storage basket 463 up and down, eliminating the need for manual feeding or removal of ingredients from the sterilization chamber 3. Simultaneously, the rotating steam exhaust pipe 63 and nozzle of the steam emission mechanism 6 cover the sides and bottom of the ingredients, achieving all-around cleaning and sterilization without manual turning. This effectively solves the problem of low cleaning efficiency in traditional steam cleaners and reduces manpower requirements. While reducing the workload, the operation time is shortened. Compared with existing equipment, the steam emission mechanism 6 of this technical solution is set at the lower end of the sterilization chamber 3. The rotary joint 61 drives the steam exhaust pipe 63 to rotate outside the storage basket 463. The steam emission nozzle 64 can deliver steam to the sides and bottom of the storage basket 463, eliminating the limitation of only having steam on both sides. At the same time, the steam generating mechanism 5 is located outside the storage mechanism 4, further supplementing the steam coverage area, solving the problem of steam emission dead corners, ensuring that there are no dead corners in contact with the raw materials, and improving the sterilization effect. In addition, the installation rail 461 and the installation block 462 of this device cooperate to facilitate the quick assembly and disassembly of the storage basket 463. The inclined layout of the controller 7 makes it convenient for operators to view and operate. The support structures such as the fixed plate 41 and the fixed arm 621 provide stable support for the electric push rod 42 and the drive motor 623, avoiding the displacement of parts during equipment operation and causing failure. The sealing cover 45 reduces steam leakage and ensures the steam concentration in the sterilization chamber 3. The synergistic effect of these structures further improves the practicality and stability of the equipment.

[0036] During the application of this device, the main electronic components and related configurations are as follows: The drive motor 623 is a three-phase asynchronous motor, model Y2-80M1-2, with a power range of 0.75-1.1kW and a speed of 2800r / min. A gearbox 624 reducer is fixedly installed at the motor, with a reduction ratio range of 5-20, used to improve torque and regulate speed. The motor is equipped with an encoder, model E6B2-CWZ6C, with a resolution of 1000-2000P / R, which can flexibly adjust rotation and provide stepless speed regulation. The controller 7 is a PLC. Controller 7, model S7-200SMARTCPUSR40, is installed on the upper front of sterilizer 3. Controller 7 features a 128×64 dot matrix OLED display screen, model SSD1306, used to display equipment operating parameters. Heating wire 53 is a nickel-chromium alloy heating wire, model Cr20Ni80, with a power range of 1-2kW and an operating voltage of 220V. Water inlet valve 54 is an electromagnetic water inlet valve, model 2W-160-15, and drain valve is an electromagnetic drain valve, model 2W-200-20. All operating voltages are 24VDC. The drain valve is located at the bottom of the sterilization line. The circuit connection uses an external 220VAC power supply to power the controller 7, drive motor 623, and heating wire 53. The output of the controller 7 is electrically connected to the drive motor 623, heating wire 53, inlet valve 54, and drain valve. The encoder signal terminal is electrically connected to the input of the controller 7 to provide feedback on motor speed. During use, a PT100 temperature sensor can be installed inside the sterilization chamber 3 to monitor the temperature inside the chamber in real time, depending on specific application requirements. A position sensor, model E3F-DS30C4, is installed at the location of the suspended basket 463 to detect whether the basket 463 is in place. A liquid level sensor, model YL69, is installed in the water tank 52 to monitor the water level in the tank. The signal terminals of these sensors are electrically connected to the input terminals of the controller 7. The controller 7 receives the signals from each sensor and controls the various electronic components to work together, such as controlling the heating wire 53 to heat and generate steam, driving the motor 623 to rotate the rotary joint 61, and controlling the water inlet valve 54 to add water and the drain valve to drain water, thereby realizing the steam emission sterilization process.

Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.
