Description

Technical Field

[0001] The utility model relates to the technical field of injection water insulation, and more specifically, to an injection water insulation circulation device. Background Art

[0002] Water for injection refers to water that complies with the provisions of the Chinese Pharmacopoeia Water for Injection. Water for injection is water obtained by distilling distilled water or deionized water, so it is also called heavy distilled water. In order to effectively control microbial contamination and the level of bacterial endotoxins at the same time, the design and manufacture of purified water and water for injection systems have two major characteristics: one is that disinfection / sterilization facilities are increasingly used in the system; the other is that the pipeline distribution system has evolved from traditional water delivery pipelines to circulation pipelines; water for injection needs to be stored at high temperatures to prevent microbial contamination, so a heat preservation circulation device is proposed to keep water for injection warm.

[0003] After searching, for example, a Chinese patent application with application number CN201620533588.1 discloses an injection water insulation device. When the industrial boiler is running during the day, the electric boiler is closed, the first control valve is opened, and the second control valve is closed, and the injection water is insulated by the industrial boiler. At night, the industrial boiler is closed, the electric boiler is started, the first control valve is closed, and the second control valve is opened, and the injection water is insulated by the electric boiler, which greatly reduces energy consumption while taking into account the safety of electric heating. At the same time, the electric boiler can be installed near the point of use, reducing the length of the steam pipe network and further reducing energy consumption; the overall structure is simple and the cost is low.

[0004] However, when the above technical solution is used to heat and insulate the injection water, the injection water needs to flow through multiple pipes, and the multiple pipes are exposed to the air, resulting in heat loss of the injection water flowing through, thus affecting the insulation effect. Utility Model Content

[0027] In order to monitor the injection water temperature in the heat-conducting cylinder 12 at any time, a temperature detection device 2 capable of detecting the injection water temperature at any time is provided at the lower end of one side of the heat-insulating shell 1, which is used to monitor the injection water temperature in the heat-conducting cylinder 12 at any time and issue instructions according to the temperature;

[0028] like Figure 3 As shown, the temperature detection device 2 includes a heat-insulating tube 21, which passes through one side of the heat-insulating shell 1, one end of the heat-insulating tube 21 is connected to the heat-conducting tube 12, a heat-conducting rod 23 is fixedly provided on the inner side of the heat-insulating tube 21, a temperature controller 22 is fixedly provided on one end of the heat-insulating tube 21, an input end of the temperature controller 22 is fixedly connected to one end of the heat-conducting rod 23, and a wire 24 is fixedly provided on the output end of the temperature controller 22. The heat-conducting rod 23 in the heat-insulating tube 21 is arranged in the heat-conducting tube 12, so as to conduct the temperature of the injection water in the heat-conducting tube 12. When the temperature of the injection water in the heat-conducting tube 12 is lower than the set temperature of the temperature controller 22, the temperature controller 22 issues a command to operate the heating generator 31 through the wire 24, thereby reducing manual supervision.

[0029] Furthermore, in order to heat the hot water in the heat-conducting liquid cavity 11 and heat and keep the water for injection warm, a heating and heat-keeping device 3 capable of heating the hot water in the heat-conducting liquid cavity 11 is provided inside the heat-conducting liquid cavity 11, which is used to heat the hot water in the heat-conducting liquid cavity 11 and achieve heating and heat preservation;
