Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchange for bottle washing machines, and particularly relates to a heat exchange device for bottle washing machines. Background Art

[0002] The bottle washing machine consists of a stainless steel water pump, a high-pressure nozzle, an electrical box, etc. It is a special equipment suitable for brush-type cleaning and water-flushing cleaning of glass bottles, plastic bottles, etc., which can be used alone or in combination. It adopts high-pressure backwash spraying to ensure that the debris on the bottle wall can be separated and dropped into the water tank in time.

[0003] When a bottle washing machine is cleaning glass bottles, it needs to use hot water for rinsing. After the hot water is used to rinse the glass bottles, the hot water will become waste water. The waste water and residual heat after rinsing can be reasonably recovered and utilized through a heat exchange device. The existing heat exchange device for bottle washing machines generally pumps the waste water into the heat exchange box during use, and then performs heat exchange through the heat exchange tube. Since the heat exchange tube is in direct contact with the waste water during use, a lot of impurities will adhere to the outside of the heat exchange tube during long-term use. The accumulated impurities will affect the heat exchange effect of the heat exchange tube, making it inconvenient for people to use. Utility Model Content

[0022] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1 - Figure 7As shown, a heat exchange device for a bottle washing machine includes a heat exchange box 1, the interior of the heat exchange box 1 is equipped with a heat exchange tube 2 with a serpentine structure, both ends of the heat exchange tube 2 extend to the outside of the heat exchange box 1, and the interior of the heat exchange box 1 is equipped with a cleaning mechanism for cleaning the heat exchange tube 2, the cleaning mechanism includes a cleaning plate 3 located in the heat exchange box 1, and a plurality of cleaning ports opened on the cleaning plate 3 and sleeved on the outside of the heat exchange tube 2, a mounting cylinder 8 is installed on the top of the heat exchange box 1, a sewage cylinder 9 integrated with the mounting cylinder 8 is installed on one side of the mounting cylinder 8, and the mounting cylinder 8 is connected to the sewage cylinder 9, and a driving mechanism for driving the cleaning plate 3 to reciprocate is installed on the outside of the heat exchange box 1, the driving mechanism includes two movable plates 4 installed on one side of the cleaning plate 3 and extending to the outside of the heat exchange box 1, and a fixing ring 15 installed on the top of the heat exchange box 1, between the two movable plates 4 A connecting plate 5 located outside the heat exchange box 1 is installed, and a push rod 6 is installed on one side of the connecting plate 5. The interior of the fixed ring 15 is rotatably connected to the rotating column 7. The outside of the rotating column 7 is provided with an inclined annular groove 11, and the inside of the annular groove 11 is slidably connected to the ball 18. The top of the push rod 6 is fixedly connected to the outside of the ball 18, and the outside of the mounting cylinder 8 is rotatably connected to the rotating rod 12 fixedly connected to the rotating column 7. A rotating motor is installed on the outside of the mounting cylinder 8, and a driving wheel 13 is installed on the output end of the rotating motor. A driven wheel 14 meshing with the driving wheel 13 is installed on the outside of the rotating rod 12. A water inlet pipe 21 is installed on the top of the sewage barrel 9, and a connecting pipe 22 extending into the heat exchange box 1 is installed on the bottom of the mounting cylinder 8. A drain pipe 20 is installed at the bottom of the heat exchange box 1. Waste water entering the heat exchange box 1 can be discharged through the drain pipe 20.

[0025] It should be noted that, during the use of this heat exchange device for a bottle washing machine, the water inlet end of the heat exchange tube 2 can be connected to the water supply pipe of an external water supply device, and the water supply can be started through the external water supply device, so that clean water can enter the interior of the heat exchange tube 2, and the drain outlet of the bottle washing machine is connected to the water inlet pipe 21 through a pipe. The waste water discharged by the bottle washing machine will enter the interior of the sewage cylinder 9, and the waste water entering the interior of the installation cylinder 9 will enter the interior of the heat exchange box 1 through the connecting pipe 22. Under the exchange of cold and hot water, the discharged waste water will transfer heat to the heat exchange tube 2, thereby heating the clean water inside the heat exchange tube 2. When it is necessary to clean the outside of the heat exchange tube 2, the rotating motor can be started. The rotating motor will drive the driving wheel 13 to rotate. With the cooperation of the driving wheel 13 and the driven wheel 14, the rotating rod 12 will rotate. Driven by the rotating rod 12, the rotating column 7 will rotate. At this time, the push rod 6 will reciprocate left and right with the rotation of the annular groove 11. The ball 18 will slide in the annular groove 11, and then drive the connecting plate 5 to reciprocate. Driven by the connecting plate 5, the two movable plates 4 will drive the cleaning plate 3 to reciprocate, so that the outer wall of the heat exchange tube 2 can be cleaned, reducing impurities adhering to the outside of the heat exchange tube 2 during long-term use, thereby improving the heat exchange efficiency. The drainage end of the heat exchange tube 2 can be connected to the water inlet of the bottle washing machine through a pipe.

[0026] Example 2

[0027] like Figure 3 、 Figure 4 and Figure 7 As shown, the difference between this embodiment and embodiment 1 is that the sewage barrel 9 has a trumpet-shaped structure, which allows impurities to slide into the sewage barrel 9 along the slope. A filter screen 16 is installed at the connection between the mounting barrel 8 and the sewage barrel 9. The end of the rotating rod 12 away from the rotating column 7 extends into the mounting barrel 8 and passes through the filter screen 16 and extends into the sewage barrel 9. The outside of the rotating rod 12 is provided with multiple scrapers 17 located in the sewage barrel 9 and in contact with one side of the filter screen 16. A sewage outlet is opened on the side of the sewage barrel 9 away from the mounting barrel 8. A sealing cover 10 for sealing the sewage outlet is screwed on one end of the sewage barrel 9. A sealing plate 19 used in conjunction with the sewage outlet is installed on the inner side of the sealing cover 10. The sealing plate 19 is made of rubber. The sealing plate 19 can reduce the occurrence of water seepage. The impurities cleaned by the scraper 17 will enter the sewage barrel 9. When it is necessary to clean the impurities inside the sewage barrel 9, the sealing cover 10 can be directly unscrewed from the outside of the sewage barrel 9, so that it can be cleaned directly.

[0028] The further improved feature of this embodiment is that the wastewater entering the sewage barrel 9 will first be filtered through the filter screen 16, and the filtered wastewater will enter the installation barrel 8, which can not only reduce the impurities in the wastewater, but also reduce the impurities adhering to the outside of the heat exchange tube 2, thereby improving the heat exchange effect. When the rotating rod 1 rotates, it will drive multiple scrapers 17 to rotate, and the scraper 17 will clean one side of the filter screen 16 to reduce the clogging of the filter screen 16 during filtration.

[0029] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
