Abstract
Description
Technical Field
[0001] This utility model belongs to the field of PE square bottle cooling technology, specifically relating to a PE square bottle tunnel cooler. Background Technology
[0002] In modern industrial production, especially in the beverage and food industries, PE square bottles are commonly used packaging containers. The cooling process is crucial in their production. After high-temperature filling, PE square bottles need to be cooled by a tunnel bottle cooler to quickly reduce their temperature to a suitable range, ensuring product quality and smooth subsequent processing.
[0003] Existing bottle coolers typically use large amounts of cooling water to spray or immerse PE square bottles during the cooling process. However, this cooling water is often discharged directly after use, resulting in serious waste of water resources. This water-intensive cooling method not only increases the production costs of enterprises but also puts considerable pressure on the environment. Utility Model Content
[0004] The purpose of this invention is to provide a tunnel cooling machine for PE square bottles to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a PE square bottle tunnel cooling machine, comprising:
[0006] A frame, the top of which is connected to a cooling rack and the cooling rack is provided with several glass windows;
[0007] A plate heat exchanger is provided on one side of the frame and is used to cool and reduce the temperature of PE square bottles in the cooling rack. Several cooling water tanks are connected to the surface of the cooling rack and the cooling water tanks are connected to the plate heat exchanger through a first connecting pipe. A water tank is provided in the bottom of the cooling rack and several second connecting pipes are connected to the bottom of the water tank and the second connecting pipes are connected to the cooling water tanks.
[0008] The first chain plate conveyor belt is located on one side of the frame and is used to transport PE square bottles into the cooling rack for cooling.
[0009] Preferably, the bottom of the frame is equipped with several water pumps, the inlet of the water pumps is connected to the cooling water tank through a pipe, and the outlet of the water pumps is connected to the spray pipe inside the cooling rack through a pipe.
[0010] Preferably, one set of water pumps is connected to the plate heat exchanger through a third connecting pipe, and several spray heads are evenly distributed on the surface of the spray pipe.
[0011] Preferably, the cooling rack is provided with a main conveyor belt, and a second chain plate conveyor belt for discharging material is provided on the frame and on one side of the main conveyor belt.
[0012] Preferably, a fan for drying PE square bottles is provided inside the cooling rack and located at the second chain conveyor belt.
[0013] Preferably, both the first and second chain conveyor belts are equipped with horizontal glass sliding doors.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] (1) The bottle cooler is equipped with a complete cooling water circulation system. After the cooling water is cooled by the plate heat exchanger, it enters the cooling water tank through the first connecting pipe. Then, the water pump sprays the cooling water in the cooling water tank onto the PE square bottles in the cooling rack for cooling. The sprayed cooling water falls into the water tank, and the cooling water in the water tank returns to the cooling water tank through the second connecting pipe, realizing recycling and greatly reducing the consumption of water resources and reducing the water cost of enterprises.
[0016] (2) The use of plate heat exchangers can efficiently cool the cooling water and ensure that there is a continuous and stable low-temperature cooling medium in the cooling rack. The spray pipes in the cooling rack, under the action of the water pump, disperse the cooling water into fine water flow and spray it evenly on the PE square bottle, which increases the cooling area and heat exchange efficiency. It can quickly cool the PE square bottle after high temperature filling to a suitable temperature and effectively ensure product quality.
[0017] (3) PE square bottles enter the cooling rack from the first chain plate conveyor belt, are cooled on the main conveyor belt, and are finally discharged via the second chain plate conveyor belt. The whole process is continuous and highly automated, reducing manual intervention and improving production efficiency.
[0018] (4) The fan installed in the cooling rack at the second chain plate conveyor belt can dry the surface moisture of the PE square bottle before it is discharged, so as to avoid residual water droplets affecting the appearance of the product or causing pollution in the subsequent packaging process, thereby further improving the quality of the product and the packaging effect.

[0023] 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.
[0024] This utility model provides, for example Figure 1-3 The PE square bottle tunnel cooler shown includes:
[0025] A frame 1, with a cooling rack 2 connected to the top of the frame 1 and a plurality of glass windows 3 provided on the cooling rack 2;
[0026] Plate heat exchanger 4 is located on one side of frame 1 and is used to cool and lower the temperature of PE square bottles in cooling rack 2. Several cooling water tanks 5 are connected to the surface of cooling rack 2 and the several cooling water tanks 5 are connected to plate heat exchanger 4 through first connecting pipe 6. A water tank 7 is provided in the bottom of cooling rack 2 and several second connecting pipes are connected to the bottom of water tank 7 and the second connecting pipes are connected to cooling water tanks 5.
[0027] The first chain plate conveyor belt 8 is located on one side of the frame 1 and is used to transport PE square bottles into the cooling rack 2 for cooling.
[0028] The bottom of the frame 1 is equipped with several water pumps 9. The water inlet of the water pump 9 is connected to the cooling water tank 5 through a pipe, and the water outlet is connected to the spray pipe in the cooling rack 2 through a pipe.
[0029] One set of water pumps 9 is connected to the plate heat exchanger 4 through the third connecting pipe 13. Several spray heads are evenly distributed on the surface of the spray pipe. Cooling water can be sprayed onto the PE square bottle on the main conveyor belt 12 through the spray heads evenly distributed on the spray pipe to cool down the PE square bottle.
[0030] The cooling rack 2 is equipped with a main conveyor belt 12, and a second chain plate conveyor belt 10 for discharging material is provided on the frame 1 and on one side of the main conveyor belt 12.
[0031] A fan for drying PE square bottles is provided inside the cooling rack 2 and located at the second chain conveyor belt 10.
[0032] Both the first chain conveyor belt 8 and the second chain conveyor belt 10 are equipped with horizontal glass sliding doors 11. The presence of the horizontal glass sliding doors 11 not only prevents the escape of steam or heat, but also allows operators to easily observe the conveying status and processing of items on the conveyor belt due to the transparency of the glass.
[0033] This PE square bottle tunnel cooler uses an SEW geared motor as the power source for its conveying system, controlled by a Danfoss frequency converter. The system is driven by a toothed synchronous belt. This combination ensures smooth start-stop, uniform acceleration, and precise positioning of the first chain conveyor belt 8, the second chain conveyor belt 10, and the main conveyor belt 12. The filled PE square bottles are first sorted and conveyed by a bottle unloading and palletizing machine. The side guards of the unloading and palletizing machine are pneumatically controlled, allowing for precise adjustment of the position according to the actual situation of the bottle stack. This ensures that the PE square bottles enter smoothly and do not tip over after entering the first chain conveyor belt 8, resulting in rapid acceleration and accurate positioning.
[0034] By placing the PE square bottles to be cooled on the first chain conveyor belt 8, which is driven by an SEW geared motor, the PE square bottles can be smoothly transported to the cooling rack 2. Inside the cooling rack 2, the PE square bottles are transported vertically by the first chain conveyor belt 8 with stable power transmission. When approaching the horizontally set main conveyor belt 12, a smooth connection is achieved by using the transition structure at the main conveyor belt 12. The transition structure generally includes an inclined section and a horizontal section. The inclined section gradually changes the conveying direction of the bottles, turning from the first chain conveyor belt 8 to approaching the main conveyor belt 12, ensuring that the bottles can smoothly transition to the main conveyor belt 12.
[0035] The core components of the cooling circulation system are the plate heat exchanger 4 and the cooling water tank 5. The plate heat exchanger 4 is installed on one side of the frame 1 to cool the cooling medium. Multiple cooling water tanks 5 are connected to the surface of the cooling rack 2. The cooling water tanks 5 are connected to the plate heat exchanger 4 through the first connecting pipe 6 to form a circulation path for the cooling medium. After being cooled by the plate heat exchanger 4, the water in the cooling water tank 5 flows into the cooling water tank 5 through the first connecting pipe 6 under the action of gravity and the water pump 9. Under the action of the water pump 9, the cooling water in the cooling water tank 5 is transported to the spray pipe in the cooling rack 2. The spray nozzles evenly distributed on the spray pipe spray the cooling water onto the PE square bottles on the main conveyor belt 12. After absorbing the heat of the bottles, the water becomes hot water and flows into the water tank 7 at the bottom of the cooling rack 2. The hot water in the water tank 7 returns to the cooling water tank 5 through the second connecting pipe and re-enters the plate heat exchanger 4 for cooling. This cycle repeats continuously to achieve continuous recycling of cooling water and efficient cooling of the PE square bottles.
[0036] When the cooled PE square bottle moves to the position of the second chain plate conveyor belt 10 along the main conveyor belt 12, the fan at this position is started. The air blown by the fan dries the residual moisture on the surface of the PE square bottle, preventing residual water droplets from affecting the product appearance or causing contamination in the subsequent packaging process, thus ensuring product quality and packaging effect. The dried PE square bottle is smoothly connected to the second chain plate conveyor belt 10 through the transition structure at the other end of the main conveyor belt 12, and the dried PE square bottle is transported to the second chain plate conveyor belt 10 for discharge.
[0037] This utility model uses a Siemens S7-1500 series PLC as the control core, paired with a Siemens interface. The PLC programs the input and output points of the program controller onto the interface, achieving a tight integration between the electrical system and the operating interface. Operators issue commands through buttons and menus on the operating interface, such as starting the equipment, adjusting the conveyor speed, and setting the cooling temperature. After these commands are parsed by the PLC, they control the actions of various actuators. The equipment also directly programs the running status onto the interface. When a fault occurs and the machine stops, the operator selects the fault query interface, and the equipment will automatically and intelligently report the fault point, facilitating quick troubleshooting and problem solving. Furthermore, the main structure of the frame 1 and cooling rack 2 is made of SUS304 stainless steel, which is not only durable but also meets hygiene standards. The horizontal glass sliding door 11, equipped with safety glass, prevents the release of steam or heat, avoiding safety hazards such as burns to operators, while maintaining stable temperature and humidity inside the cooling rack 2, improving the cooling effect. The glass window 3 on the cooling rack 2 allows operators to observe the cooling status of the PE square bottles and the operating status of the equipment at any time without opening the cooling rack 2, improving operational safety.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
