DETAILED DESCRIPTION
[0025] like Figures 1 to 8 As shown, the utility model is a cooling device for a nitrogen purification bed, comprising a nitrogen purification bed 1 and a desorption device 2, wherein the desorption device 2 comprises: a desorption fan 21, a heater 22, a heat exchanger 23, a first condenser 24 and a second condenser 25. One side of the desorption fan 21 is connected to the heater 22, and the desorption fan 21 blows air into the heater 22. One side of the heater 22 is connected to the nitrogen purification bed 1, and the hot air in the heater 22 blows toward the nitrogen purification bed 1. One end of the nitrogen purification bed 1 is connected to the heat exchanger 23, and one side of the heat exchanger 23 is connected to the first condenser 24, and the first condenser 24 can cool down the hot air coming out of the heat exchanger 23. One side of the first condenser 24 is connected to the second condenser 25, and one end of the second condenser 25 can cool down the heat exchanger 23. A decontamination device 3 is connected to each of the first condenser 24 and the second condenser 25.
[0026] The first condenser 24 (the structure of the first condenser 24 is consistent with that of the second condenser 25 in this article) includes: a condenser tube 242, a shell 241 and a fan 243. The condenser tube 242 is located inside the shell 241, and the fan 243 is fixedly connected to the outside of the shell 241. The impurity removal device 3 includes: an inlet pipe 31, a fixed cylinder 32, a motor 35, a fixed frame 34, a rotating plate 37, a torsion spring 39, a rotating shaft 310, an inclined plate 38, a slag outlet 312, a filter layer 311 and a water outlet pipe 33. One end of the water inlet pipe 31 is connected to the fixed cylinder 32, and one end of the fixed cylinder 32 is connected to the condenser tube 242. Water enters the fixed cylinder 32 and the condenser tube 242 through the water inlet pipe 31. The fixed frame 34 is fixedly connected to the inner side of the fixed cylinder 32, and the motor 35 is fixedly connected to the fixed frame 34, so that the motor 35 is fixedly arranged in the fixed cylinder 32. The end of the motor 35 close to the water inlet pipe 31 is tapered to reduce the impact of the water flow on the motor 35. The filter layer 311 is located in the fixed cylinder 32 to filter the water in the fixed cylinder 32. The output shaft of the motor 35 is fixedly connected to the rotating plate 37, and the motor 35 drives the rotating plate 37 to rotate. The rotating shaft 310 is connected to one end of the rotating plate 37, the torsion spring 39 is connected to the rotating shaft 310, and one end of the inclined plate 38 is fixedly connected to the torsion spring 39, and the torsion spring 39 allows the inclined plate 38 to reset. One end of the inclined plate 38 fits the inner wall of the fixed cylinder 32 to scrape out impurities on the inner wall of the fixed cylinder 32. The width of the inclined plate 38 is smaller than the width of the slag outlet 312, so that the inclined plate 38 can extend into the slag outlet 312. The slag outlet 312 is located on the side of the fixed cylinder 32, and the slag outlet 312 is penetrated by a baffle 5 to prevent impurities from flowing out. The other end of the condenser pipe 242 is connected to the water outlet pipe 33 to discharge the water in the condenser pipe 242. Two baffles 4 are connected to the slag outlet 312, and the two baffles 4 are inclined.
[0027] The filter layer 311 includes: a filter screen 3111, a gravel layer 3112 and a bamboo charcoal layer 3113. The filter screen 3111 is located inside the fixed cylinder 32 and is used to intercept solid impurities. The filter screen 3111 is close to the rotating plate 37 so that the rotating plate 37 can scrape out the impurities on the filter screen 3111. A retaining ring 36 is connected to the inside of the fixed cylinder 32 to prevent turbulent flow of impurities so that the impurities can only be scraped out in the direction of rotation of the rotating plate 37. The gravel layer 3112 and the bamboo charcoal layer 3113 are both connected to the inside of the fixed cylinder 32.
[0028] The working process of the above scheme: when the nitrogen purification bed 1 starts to operate the desorption fan 21, the first condenser 24 and the second condenser 25 start to operate, the desorption fan 21 blows air to the heater 22, and the heater 22 heats the nitrogen purification bed 1. At this time, the second condenser 25 starts to operate, and the heat exchanger 23 is used to exchange heat between the second condensation wind and the first hot wind. After the first hot wind is cooled, the temperature is basically lower than the outlet temperature of the first condenser 24. At this time, the cooling function of the first condenser 24 can be turned off. This control method can reduce the start-up time of the condenser water pump to achieve energy-saving effects. When the first condenser 24 and the second condenser 25 are in operation, the water flows into the water inlet pipe 31, and then enters the condenser pipe 242 through the fixed cylinder 32. When it is necessary to turn on the impurity removal device 3, the motor 35 is started to drive the rotating plate 37 to rotate, and the rotating plate 37 drives the inclined plate 38 to scrape out the impurities intercepted on the outside of the filter screen 3111. When the inclined plate 38 rotates and passes through the slag outlet 312, the torsion spring 39 drives the inclined plate 38 to push, and the inclined plate 38 pushes the impurities into the slag outlet 312. After the impurities enter the slag outlet 312 through the inclined baffle plate 4, the impurities are blocked by the baffle plate 4 to prevent the impurities from re-entering the fixed cylinder 32. The impurities are discharged from the slag outlet 312 by pulling out the baffle plate 5.
[0029] The above scheme has the following beneficial effects: the desorption device 2 can reduce the number of times the condenser is used, thereby achieving energy saving; the impurity removal device 3 can filter the water entering the condenser tube 242 and discharge impurities; the motor 35 drives the rotating plate 37 to rotate to scrape out impurities on the filter screen 3111, and then the impurities are pushed into the slag outlet 312 through the inclined plate 38, and the impurities are prevented from flowing out of the slag outlet 312 by the guardrail 4, and the impurities are discharged by pulling out the baffle 5.
[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
