Abstract
Description
Technical Field
[0001] This utility model relates to the field of sterilization technology for tank products, specifically a multi-layer sterilization device. Background Technology
[0002] Sterilization equipment for canned products typically uses a continuous conveyor belt or chain system to transport the canned products through a high-temperature sterilization zone. Within this zone, the cans are heated and sterilized using steam or hot water jets. The basic principle of sterilization is to kill bacteria and other microorganisms inside the can using high temperatures, thereby meeting food safety requirements.
[0003] Current can sterilization equipment on the market has some drawbacks. For example, these devices require relatively long conveyor channels to allow sufficient sterilization time for the canned products. Because the cans are transported on the conveyor belt, the bottom is obscured, resulting in slower or uneven heating at the bottom, affecting overall sterilization coverage. Uneven sterilization can lead to food safety issues, affecting product shelf life and consumer health. Current solutions typically compensate for uneven heating by increasing the sterilization temperature or extending the sterilization time, but this increases energy consumption and reduces product quality.
[0004] Therefore, there is an urgent need for a multi-layer sterilization device to solve the aforementioned technical defects. Utility Model Content
[0005] The purpose of this invention is to provide a multi-layer sterilization device to solve the problems mentioned in the background art, such as the need to build a sterilization channel over a long distance and uneven heating at the bottom of the tank, which affects the sterilization coverage.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer sterilization device, comprising a frame and a right upright plate. The right upright plate is fixedly mounted on the right side of the frame, and a feeding chain is obliquely arranged at the front end of the right upright plate. A left upright plate is fixedly mounted on the left side of the frame. The frame contains multiple transmission channels. A sprocket and chain transmission mechanism is installed behind the left upright plate. A transmission chain is installed at the sprocket and chain transmission mechanism. Multiple sets of rectangular tubes are evenly fixed at the top of the feeding chain and the transmission chain. An overlapping plate is fixed at the front end of the frame. Each set of transmission chains is located above the overlapping plate. Four sets of crankshaft connecting rod mechanisms are arranged on the left side of the outer wall of the left upright plate. A telescopic rod is installed on the right side of the crankshaft connecting rod mechanism. A push-pull plate is fixedly connected to the right side of the telescopic rod. The push-pull plate is located below the initial section of the overlapping plate. A set of arc-shaped inner guide plates is fixedly connected to the left and right sides of the bottom end of the overlapping plate. An arc-shaped outer guide plate is arranged below the arc-shaped inner guide plate. The arc-shaped outer guide plate connects to the next set of overlapping plates.
[0007] Preferably, the frame body has ten layers of transmission channels, with the upper six layers being steam sterilization sections and the lower four layers being cooling and ambient temperature sections. The frame body has multiple sets of steam spray pipes installed above each layer of transmission channels in the steam sterilization section, and multiple sets of cooling spray pipes installed below each layer of transmission channels in the cooling and ambient temperature sections.
[0008] Preferably, a limiting bearing for stabilizing the movement of the push-pull plate is installed at the rear of the frame via a bearing seat.
[0009] Preferably, both the inner and outer arc guide plates are hook-shaped arc plates, and the push-pull plate is made of copper.
[0010] Preferably, a side-push tank mechanism is provided on the right side of the feeding chain, and the feeding chain is connected to the first layer of the transmission channel.
[0011] Preferably, a can-discharge mechanism is installed at the bottom right side of the outer wall of the right upright plate, and the tenth layer of the transmission channel is connected to the discharge channel of the can-discharge mechanism.
[0012] Compared with the prior art, the beneficial effects of this utility model are: this multi-layer sterilization equipment not only achieves multi-channel sterilization, but also reciprocating shaking transmission, uniform heating, high sterilization coverage, and good effect.
[0013] Equipped with a sprocket and chain transmission mechanism, a crankshaft connecting rod mechanism, a side-push tank mechanism, and a tank-discharging mechanism, the equipment features ten channels. The first six channels are sterilization sections. After the tanked product is conveyed upwards to the first channel by the feeding chain, driven by the sprocket and chain transmission mechanism, the transmission chain causes the product to roll from right to left at the overlapping plate. Guided by the inner and outer arc-shaped guide plates, it smoothly rolls down to the push-pull plate of the next channel. In the initial transmission section of the next channel, the crankshaft connecting rod pulls the telescopic rod in a linear reciprocating motion, causing the product to sway slightly back and forth on the push-pull plate while continuing to move forward. The upper six channels are sprayed with steam through steam nozzles, raising the internal temperature of the entire equipment and sterilizing the product. The reciprocating motion ensures thorough sterilization. By gently swaying the fluid inside the tank, the surface area for uniform heating is increased, improving the sterilization coverage and ensuring a comprehensive sterilization effect. After six layers of sterilization, the product arrives at the cooling section on the lower four layers. The cooling section operates in the same way as the steam section, but cooling gas is sprayed through cooling nozzles to lower the product to room temperature, achieving a combination of sterilization and cooling. The integrated process is highly efficient. When the product enters, it is pushed into the feeding chain by the side-push tank mechanism and limited by multiple sets of rectangular tubes, allowing it to rise steadily at an incline to the first layer of the equipment. After sterilization and cooling, the product arrives at the outlet and rolls into the channel of the can-discharging mechanism through an arc plate. By controlling the speed of the motors of the side-push tank mechanism and the can-discharging mechanism, uniform feeding and discharging are achieved, saving a lot of manpower.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This utility model provides an embodiment of a multi-layer sterilization device, including a frame 17 and a right upright plate 3. The right upright plate 3 is fixedly mounted on the right side of the frame 17, and a feeding chain 4 is obliquely arranged at the front end of the right upright plate 3. A left upright plate 14 is fixedly mounted on the left side of the frame 17. The frame 17 has a multi-layer transmission channel inside. A sprocket and chain transmission mechanism 10 is installed behind the left upright plate 14. A transmission chain 7 is installed at the sprocket and chain transmission mechanism 10. Multiple sets of rectangular tubes 5 are evenly fixed at the top of the feeding chain 4 and the transmission chain 7. An overlapping plate 8 is fixed at the front end of the frame 17. Each set of transmission... The conveyor chain 7 is located above the overlapping plate 8. Four sets of crankshaft connecting mechanism 13 are provided on the left side of the outer wall of the left upright plate 14. A telescopic rod 15 is installed on the right side of the crankshaft connecting mechanism 13. A push-pull plate 9 is fixedly connected to the right side of the telescopic rod 15. The push-pull plate 9 is located below the initial section of the overlapping plate 8. A set of arc-shaped inner guide plates 11 are fixedly connected to the left and right sides of the bottom end of the overlapping plate 8. An arc-shaped outer guide plate 12 is provided below the arc-shaped inner guide plate 11. The arc-shaped outer guide plate 12 is connected to the next set of overlapping plates 8. Both the arc-shaped inner guide plate 11 and the arc-shaped outer guide plate 12 are hook-shaped arc plates. The push-pull plate 9 is made of copper plate.
[0021] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the equipment has ten channels, with the first six being sterilization sections. After the tank product is conveyed upwards to the first channel by the feeding chain 4, the conveyor chain 7 drives the product to roll from right to left at the overlapping plate 8 under the drive of the sprocket chain transmission mechanism 10. After being guided by the inner arc guide plate 11 and the outer arc guide plate 12, the product rolls smoothly down to the push-pull plate 9 of the next channel. In the initial transmission section of the next channel, the crankshaft connecting rod mechanism 13 pulls the telescopic rod 15 to make a linear reciprocating motion, causing the product to make a small reciprocating sway on the push-pull plate 9 while still moving forward. The reciprocating motion ensures that the product is fully sterilized. Through the small reciprocating sway, the fluid in the tank can increase the uniform heating area during the swaying, thereby improving the sterilization coverage.
[0022] The frame 17 has ten layers of transmission channels. The upper six layers are steam sterilization sections, and the lower four layers are cooling and ambient temperature sections. The frame 17 has multiple sets of steam nozzles 6 installed above each layer of transmission channels in the steam sterilization section, and multiple sets of cooling nozzles 16 installed below each layer of transmission channels in the cooling and ambient temperature section.
[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper six channels of the equipment spray steam through steam nozzles 6, which raises the temperature inside the entire equipment and sterilizes the product. After six layers of sterilization, the product arrives at the lower four cooling sections. The cooling sections operate in the same way as the steam sections, but cooling gas is sprayed through cooling nozzles 16 to lower the product to room temperature, thus combining sterilization and cooling.
[0024] A limiting bearing 18 for stabilizing the movement of the push-pull plate 9 is installed at the rear of the frame 17 via a bearing seat. A side push tank mechanism 2 is provided on the right side of the feeding chain 4. The feeding chain 4 is connected to the first layer of the transmission channel. A can discharge mechanism 1 is installed at the bottom right side of the outer wall of the right vertical plate 3. The tenth layer of the transmission channel is connected to the discharge channel of the can discharge mechanism 1.
[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the product enters, it is pushed into the feeding chain 4 by the side push tank mechanism 2, and the product is limited by multiple sets of rectangular tubes 5, so that it rises stably and tilts to the first layer of the equipment. After sterilization and cooling, the product comes to the outlet and rolls into the channel of the can-discharging mechanism 1 through the arc plate. By controlling the speed of the motors of the side push tank mechanism 2 and the can-discharging mechanism 1, uniform feeding and discharging are achieved.
[0026] Working principle: The product is pushed into the feeding chain 4 by the side-push tank mechanism 2, and is limited by multiple sets of rectangular tubes 5, causing it to rise stably and tilted to the first layer of the equipment. The equipment has ten layers of channels, with the first six layers being sterilization sections. After the product in the tank is transferred upwards from the feeding chain 4 to the first layer, it is driven by the sprocket chain transmission mechanism 10, and the transmission chain 7 drives the product to roll from right to left at the overlapping plate 8. After being limited and guided by the inner arc guide plate 11 and the outer arc guide plate 12, it rolls smoothly down to the push-pull plate 9 of the next layer of channels. In the initial section of the next layer of transmission, the crankshaft connecting rod mechanism 13 pulls the telescopic rod 15 to make a linear reciprocating motion, so that... The product undergoes a slight reciprocating motion on the push-pull plate 9 while continuing to move forward. This reciprocating motion ensures thorough sterilization. The slight reciprocating motion also increases the uniform heating area of the fluid inside the tank. Steam is sprayed through the steam nozzles 6 in the upper six channels of the equipment, raising the temperature inside the entire equipment and sterilizing the product. After six layers of sterilization, the product arrives at the lower four cooling sections. The cooling sections operate in the same way as the steam sections, but cooling gas is sprayed through the cooling nozzles 16 to lower the product to room temperature. After sterilization and cooling, the product arrives at the outlet and is smoothly discharged into the channel of the can-discharging mechanism 1 by rolling through the arc plate.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
