Description

Technical Field

[0001] This utility model relates to the field of dairy product production technology, specifically to a feeding device for sterilization in dairy product production. Background Technology

[0002] This utility model relates to a feeding device for sterilization in dairy product production. As a pre-treatment device for the sterilization process, it is used to filter impurities and preheat dairy raw materials entering the sterilization stage. Through a two-stage gradient filtration structure, it intercepts impurities of different sizes in the raw materials, which helps to avoid impurities interfering with the sterilization effect or damaging the sterilization equipment. At the same time, the preheating function reduces the time for subsequent sterilization.

[0003] For example, Chinese patent CN216453081U discloses a rapid sterilization device for dairy product processing, including a sterilization chamber, a sterilization cavity, an inlet, a sealing component, an outlet pipe, a first solenoid valve, a heating mechanism, an exhaust component, and a mixing mechanism within the sterilization cavity. The heating mechanism includes a high-temperature circulating fan, a circular pipe, and a guide tube. The heating cavity is located within the sterilization chamber, the high-temperature circulating fan is mounted on the sterilization chamber, and the circular pipe is located within the sterilization cavity. The mixing mechanism includes a motor, a rotating rod, and a stirring rod. The motor is mounted on the sterilization chamber, the rotating rod is located within the sterilization cavity, and the stirring rod is located on the rotating rod. This device rapidly sterilizes dairy products within the sterilization cavity by rotating several stirring rods and heating the interior and inner wall of the sterilization cavity using a high-temperature circulating fan, thereby improving sterilization efficiency and reducing sterilization time.

[0004] While the above solutions have the advantages mentioned above, their disadvantages are that solid particles, clumps and other impurities in the raw materials will directly enter the sterilization chamber, which will not only affect the uniformity of sterilization, but may also wear down the stirring components and the inner wall of the equipment. In addition, the lack of raw material preheating design requires more energy to raise the temperature of the raw materials, increasing the energy consumption and time of sterilization. Utility Model Content

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a feeding device for sterilization in dairy product production, comprising: a cylinder cover; a storage cylinder on one side of the cylinder cover; a secondary filter cylinder fixedly connected to the inner wall of the interlayer between the cylinder cover and the storage cylinder; the cylinder cover, the storage cylinder, and the secondary filter cylinder being fixedly connected by bolts; a primary filter cylinder fixedly connected to the outer wall of the secondary filter cylinder; a drive fan rotatably connected to the inner wall of the bottom end of the secondary filter cylinder via a rotating shaft; side arms symmetrically fixedly connected to the outer wall of the drive fan; the side arms being L-shaped; cleaning brushes symmetrically fixedly connected to the outer wall of the side arms; a limit ring fixedly connected to the outer wall of the top end of the side arms; a heating wire provided inside the secondary filter cylinder; a butterfly valve fixedly connected to the inner wall of the drain port at the bottom end of the primary filter cylinder for discharging contaminants between the primary and secondary filter cylinders; a drain pipe fixedly connected to one side wall of the storage cylinder; and a butterfly valve fixedly connected to the inner wall of one end of the drain pipe for discharging contaminants between the storage cylinder and the primary filter cylinder.

[0006] Preferably, a feed pipe is fixedly connected to the bottom side wall of the storage cylinder, and a discharge pipe is fixedly connected to the top outer wall of the cylinder cover. The feed pipe and the drive fan are on the same plane. In use, during the sterilization feeding process of dairy product production, this equipment is driven by the feed power of the raw material itself to achieve initial conveying and process start-up. The raw material is injected into the equipment through the feed pipe on the bottom side wall of the storage cylinder. Since the feed pipe and the drive fan at the bottom of the secondary filter cylinder are on the same horizontal plane, the impact force generated when the raw material enters at high speed will directly act on the blades of the drive fan, causing the drive fan to rotate smoothly around the shaft. No additional power device such as a motor is required. Under the rotational guiding action of the drive fan, the raw material diffuses evenly to the inside of the equipment. It first contacts the primary filter cylinder located outside the secondary filter cylinder. Its larger inner diameter filter holes will trap larger impurities in the raw material, such as raw material clumps and solid particles mixed in from the outside, completing the preliminary purification and laying the foundation for subsequent filtration.

[0007] Preferably, the inner diameter of the filter holes on the outer wall of the secondary filter cartridge is smaller than that on the outer wall of the primary filter cartridge. The primary filter cartridge is placed outside the secondary filter cartridge. The raw material that has passed through the primary filter continues to permeate inward and enters the filtration range of the secondary filter cartridge. Since the inner diameter of the filter holes on the outer wall of the secondary filter cartridge is smaller than that of the primary filter cartridge, it can further trap fine impurity particles in the raw material, achieving deep purification of the raw material and ensuring that the purity of the raw material entering the subsequent sterilization process meets the standards. This avoids impurities affecting the sterilization effect or damaging the sterilization equipment. At the same time, the heating wire installed inside the secondary filter cartridge starts working synchronously. The heating wire is fixedly connected to the inner wall of the cartridge cover through a heat insulation tube, which not only ensures the stability of the installation but also effectively blocks the heat transfer to the cartridge cover, preventing the equipment shell from overheating and losing heat. The heat released by the heating wire acts on the raw material flowing through the interior of the secondary filter cartridge, preheating the raw material and raising its temperature to close to the initial temperature required for the sterilization process. This not only reduces the heating time and energy consumption of the subsequent sterilization process but also allows the raw material to reach the sterilization temperature more quickly during sterilization.

[0008] Preferably, the outer wall of the cleaning brush is slidably connected to the inner wall of the primary filter cartridge and the outer wall of the secondary filter cartridge, respectively. During continuous operation of the equipment, the rotation of the drive fan will synchronously drive the L-shaped side arms symmetrically fixed on its outer wall to rotate. The cleaning brushes on the outer wall of the side arms maintain a tight slidable connection with the inner wall of the primary filter cartridge and the outer wall of the secondary filter cartridge, respectively. As the side arms rotate, the cleaning brushes will continuously wipe and clean the surface of the filter holes of the two-stage filter cartridges, promptly removing the impurities attached to the filter holes. This helps to prevent filter hole blockage and reduce the feed flow rate, ensuring continuous and stable operation of the equipment. The limiting ring fixed on the outer wall of the top of the side arm can restrict the movement trajectory of the cleaning brush, ensuring that the cleaning brush always adheres to the surface of the filter cartridge and ensuring uniform cleaning effect. In addition, small impurities trapped between the primary and secondary filter cartridges can be discharged periodically through the butterfly valve at the bottom drain port of the primary filter cartridge. Larger impurities accumulated between the storage cylinder and the primary filter cartridge are discharged centrally through the butterfly valve on the drain pipe on one side wall of the storage cylinder, realizing the classified collection and convenient cleaning of impurities and avoiding long-term accumulation of impurities affecting the internal environment of the equipment.

[0009] Preferably, the outer wall of the heating wire is fixedly connected to the inner wall of the cylinder cover through a heat insulation tube for preheating the raw materials. The qualified raw materials that have undergone deep filtration and preheating converge towards the cylinder cover and are finally discharged through the discharge pipe on the outer wall of the top of the cylinder cover, and transported to the subsequent sterilization process. In the entire process, the feeding, filtration, preheating, cleaning, and sewage discharge links work together to form an integrated pretreatment system. The equipment is fixedly connected to the cylinder cover, storage cylinder and secondary filter cylinder with bolts to ensure the stability of the overall structure, which is conducive to improving the quality of the feeding process in dairy product production and provides a reliable guarantee for the smooth implementation of the subsequent sterilization process.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model achieves integrated raw material purification and preheating by setting a gradient filtration structure with a primary filter cartridge and a secondary filter cartridge, combined with a heating wire inside the secondary filter cartridge. The primary filter cartridge traps larger impurities, while the secondary filter cartridge further filters fine particles. This dual filtration ensures the purity of the raw materials and prevents impurities from interfering with the sterilization effect or damaging subsequent equipment. The heating wire is securely installed through a heat insulation tube, which not only blocks heat transfer and protects the equipment shell, but also raises the raw material temperature in advance, which helps to reduce energy consumption and heating time in the sterilization process.

[0012] 2. This utility model improves the problems of easy clogging and inconvenient impurity cleaning of filtration equipment by setting an L-shaped side arm linked with the drive fan, a cleaning brush, and a butterfly valve and drain pipe for graded sewage discharge. The drive fan rotates with the power of raw material feeding, which drives the cleaning brush to slide against the two-stage filter cylinder, automatically removing impurities attached to the filter holes and ensuring smooth feeding.

[0020] Please see Figure 1 - Figure 4This utility model provides a technical solution: a feeding device for sterilization in dairy product production, comprising: a cylinder cover 1, a storage cylinder 2 on one side of the cylinder cover 1, a secondary filter cylinder 3 fixedly connected to the inner wall of the interlayer between the cylinder cover 1 and the storage cylinder 2, and the cylinder cover 1, the storage cylinder 2, and the secondary filter cylinder 3 being fixedly connected by bolts; a primary filter cylinder 4 fixedly connected to the outer wall of the secondary filter cylinder 3, a drive fan 5 rotatably connected to the inner wall of the bottom end of the secondary filter cylinder 3 via a rotating shaft, and side arms 6 symmetrically fixedly connected to the outer wall of the drive fan 5. The side arm 6 is L-shaped, and a cleaning brush 7 is symmetrically fixedly connected to the outer wall of the side arm 6. A limit ring is fixedly connected to the top outer wall of the side arm 6. A heating wire 8 is provided inside the secondary filter cartridge 3. A butterfly valve 9 is fixedly connected to the inner wall of the drain port at the bottom of the primary filter cartridge 4 for discharging pollutants between the primary filter cartridge 4 and the secondary filter cartridge 3. A drain pipe 12 is fixedly connected to one side wall of the storage cylinder 2. A butterfly valve 9 is fixedly connected to the inner wall of one end of the drain pipe 12 for discharging pollutants between the storage cylinder 2 and the primary filter cartridge 4.

[0021] The bottom side wall of the storage cylinder 2 is fixedly connected to the feed pipe 10, and the top outer wall of the cylinder cover 1 is fixedly connected to the discharge pipe 11. The feed pipe 10 and the drive fan 5 are on the same plane. The inner diameter of the filter hole on the outer wall of the secondary filter cylinder 3 is smaller than the inner diameter of the filter hole on the outer wall of the primary filter cylinder 4. The primary filter cylinder 4 is placed outside the secondary filter cylinder 3.

[0022] The outer wall of the cleaning brush 7 is slidably connected to the inner wall of the primary filter cylinder 4 and the outer wall of the secondary filter cylinder 3, respectively. The outer wall of the heating wire 8 is fixedly connected to the inner wall of the cylinder cover 1 through the heat insulation tube, which is used to preheat the raw materials.

[0023] Working principle:

[0024] In use, during the sterilization feeding process of dairy product production, this equipment is driven by the raw material's own feeding power to achieve initial conveying and process start-up. The raw material is injected into the equipment through the feed pipe 10 on the bottom side wall of the storage cylinder 2. Since the feed pipe 10 and the drive fan 5 at the bottom of the secondary filter cylinder 3 are on the same horizontal plane, the impact force generated when the raw material enters at high speed will directly act on the blades of the drive fan 5, causing the drive fan 5 to rotate smoothly around the shaft. No additional power device such as a motor is required. Under the rotational guiding effect of the drive fan 5, the raw material is evenly diffused to the inside of the equipment. It first contacts the primary filter cylinder 4 located outside the secondary filter cylinder 3. Its larger inner diameter filter holes will trap larger impurities in the raw material, such as raw material clumps and solid particles mixed in from the outside, completing the preliminary purification and laying the foundation for subsequent filtration.

[0025] The raw materials that have passed through the primary filtration continue to permeate inwards, entering the filtration range of the secondary filter cartridge 3. Since the inner diameter of the filter holes on the outer wall of the secondary filter cartridge 3 is smaller than that of the primary filter cartridge 4, it can further trap fine impurity particles in the raw materials, achieving deep purification of the raw materials and ensuring that the purity of the raw materials entering the subsequent sterilization process meets the standards, avoiding impurities from affecting the sterilization effect or damaging the sterilization equipment. At the same time, the heating wire 8 installed inside the secondary filter cartridge 3 starts working synchronously. The heating wire 8 is fixedly connected to the inner wall of the cartridge cover 1 through a heat insulation tube, which not only ensures the stability of the installation, but also effectively blocks the heat transfer to the cartridge cover 1, preventing the equipment shell from overheating and losing heat. The heat released by the heating wire 8 acts on the raw materials flowing through the interior of the secondary filter cartridge 3, preheating the raw materials and raising the raw material temperature to close to the initial temperature required for the sterilization process. This not only reduces the heating time and energy consumption of the subsequent sterilization process, but also allows the raw materials to reach the sterilization temperature more quickly during sterilization.

[0026] During continuous operation of the equipment, the rotation of the drive fan 5 synchronously drives the L-shaped side arms 6, which are symmetrically fixed on its outer wall, to rotate. The cleaning brushes 7 on the outer wall of the side arms 6 maintain a tight sliding connection with the inner wall of the primary filter cartridge 4 and the outer wall of the secondary filter cartridge 3, respectively. As the side arms 6 rotate, the cleaning brushes 7 continuously wipe and clean the filter pore surfaces of the two-stage filter cartridges, promptly removing impurities adhering to the filter pores. This helps prevent filter pore blockage that could lead to a decrease in feed flow rate, ensuring continuous and stable operation of the equipment. The limiting ring fixed on the outer wall at the top of the side arms 6 restricts the movement trajectory of the cleaning brushes 7, ensuring that the cleaning brushes 7 always adhere to the surface of the filter cartridges, guaranteeing a uniform cleaning effect. In addition, small impurities trapped between the primary filter cartridge 4 and the secondary filter cartridge 3 can be periodically discharged through the butterfly valve 9 at the bottom drain port of the primary filter cartridge 4. Larger impurities accumulated between the storage cylinder 2 and the primary filter cartridge 4 are discharged centrally through the butterfly valve 9 on the drain pipe 12 on one side wall of the storage cylinder 2, achieving classified collection and convenient cleaning of impurities and preventing long-term accumulation of impurities from affecting the internal environment of the equipment.

[0027] The qualified raw materials that have undergone deep filtration and preheating converge towards the cylinder cover 1 and are finally discharged through the discharge pipe 11 on the outer wall of the top of the cylinder cover 1, and transported to the subsequent sterilization process. In the entire process, the feeding, filtration, preheating, cleaning and sewage discharge links work together to form an integrated pretreatment system. The equipment is fixedly connected to the cylinder cover 1, the storage cylinder 2 and the secondary filter cylinder 3 by bolts, which ensures the stability of the overall structure, helps to improve the quality of the feeding process in dairy product production, and provides a reliable guarantee for the smooth implementation of the subsequent sterilization process.

[0028] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
