Further, the diameters of the left inlet pipe 2 and the right outlet pipe 3 are the same, the diameter of the second matching groove 14 is the same as the diameter of the movable connecting end 9, and the diameter of the second matching groove 14 is larger than the diameter of the left inlet pipe 2, The length of the mating groove 14 minus the thickness of the movable connecting end 9 is equal to the length of a section of the right-end outlet pipe 3 connected to the third mating groove 15
Further, the width of the upper top plate 18 at the upper end of the insulated water tank 1 is greater than the width of the lower bottom plate 19, and the adjacent insulated water tanks 1 are attached to each other through the upper top plates 18.
Working principle: The adjacent heat-insulating water tanks 1 in the device can be welded to each other to form a heat-insulating mechanism to isolate the temperature of the lower part to protect the device. This device is an improvement scheme in the reference in the background art. Please refer to the parts not shown. Reference documents, in addition, the circulating water pump and the external cooling device in the device are not shown in the figure. The circulating water pump and the external cooling device are all existing technologies. When used with this device, the cooling water package 4 The temperature will never be too high, ensuring a good cooling effect of the cooling water pack 4, and the prior art will not be repeated here;
The circulating water pump is added between the left water inlet pipe 2 at the left end and the right water outlet pipe 3 at the right end in Figure 1, and there is also an external cooling device connected to the side of the circulating water pump. The external cooling device can be a metal that is bent back and forth. The quality cooling pipe can also be some other existing technology. It is not used as a main innovation here. The cooling water packs 4 inside the adjacent insulated water tanks 1 are connected through the left end water inlet pipe 2 and the right end water inlet pipe 3. The movable connecting sleeve 8 at the end of the left water inlet pipe 2 can be rotated to the right end of the insulated water tank 1 in advance. When the movable connecting end 9 is moved to the left of the second fitting groove 14 to the left, the left adjacent insulated water tank 1 The right water inlet pipe 3 on the right side is connected to the third fitting groove 15 at the left end of the movable connection sleeve 8 through threaded fitting, and the sealing ring 11 at the end of the right water inlet pipe 3 fits on the left side of the movable connection sleeve 8 to ensure the connection The sealing ring 10 also fits and seals on the inner wall of the second fitting groove 14 to ensure the sealing performance of the connection of the left water inlet pipe 2 and the connection structure between the left water inlet pipe 2 and the right water outlet pipe 3 is simple , Rotate the movable connecting sleeve 8, which is convenient to use and ensures a good sealing effect;
The heat insulation mechanism of the present invention is composed of multiple sets of heat insulation water tanks 1, and the cooling water packs 4 inside the heat insulation water tank 1 are connected by the left end water inlet pipe 2 and the right end water outlet pipe 3, so that the multiple cooling water packs 4 are connected The water circulates and the cooling and heat insulation are more uniform, and a circulating water pump is added to the left end of the water inlet pipe 2, and the other end of the circulating water pump is connected to the end right end of the water outlet pipe 3, which can circulate the water in multiple sets of cooling water packs 4 Circulation, heat and cold exchange is performed when circulating to the outside world, so that the cooled water enters the cooling water package 4 again for use, which has a high efficiency and can effectively isolate the lower temperature to protect the device;
The present invention connects the cooling water packs 4 with each other, avoids the drawback of waiting for a period of time when the cooling water pack 4 reaches saturation, and improves the corresponding efficiency of adjusting the thicker wall of the glass tube;
The connection method between the left end water inlet pipe 2 and the right end water outlet pipe 3 of the present invention is simple and has strong sealing performance, ensuring the connectivity between adjacent cooling water packs 4 and the sealing performance at the communication interface;
The inner walls of the upper and lower ends of the insulated water tank 1 are fixedly attached with multiple sets of cushion air cushions 6, which have the function of cushioning and protecting the cooling water package. The cushion 7 inside the tank cover 5 also has the function of cushioning and protection, making the device life longer It is long, and the cost of the cushion air cushion 6 and the cushion cushion 7 is low, which reduces the corresponding use cost and is suitable for promotion.
