Description

Technical Field

[0001] This application relates to the field of ammonia storage technology, and in particular to a high-pressure resistant ammonia storage device. Background Technology

[0002] Ammonia storage tanks play a crucial role in refrigeration systems. They store high-pressure liquid refrigerant from the condenser, ensuring the supply and regulation of the circulating amount of liquid refrigerant in the relevant equipment, thereby maintaining the stable operation of the system.

[0003] The published patent document CN210534970U discloses a high-pressure ammonia storage device. This patent document describes an alarm mechanism consisting of a fixed block, a fixed groove, a piston, a spring, a moving plate, two compression springs, a push-button switch, an alarm, and several overflow holes. This mechanism can immediately sound an alarm when ammonia leakage occurs, alerting people to take immediate action. Simultaneously, it slowly releases the pressure inside the storage device, preventing a high-pressure explosion. While the high-pressure ammonia storage device described above can immediately sound an alarm when a leak occurs, it also causes liquid ammonia to rapidly diffuse into the air as gaseous ammonia, potentially leading to poisoning and waste.

[0006] By adopting the above technical solution, and through the cooperation between the detection cylinder and the alarm mechanism, an alarm can be issued immediately when an ammonia storage tank leaks. The collection bladder is fixedly attached to the outer wall of the detection cylinder by the fixing unit, so that the leaked gaseous ammonia can flow into the collection bladder through the overflow hole, so that the collection bladder can collect the gaseous ammonia and prevent the gaseous ammonia from being directly released into the air, thus ensuring the personal safety of maintenance personnel.

[0007] As a preferred technical solution of this application, the alarm mechanism includes a push-button alarm, which is embedded in the top of the detection cylinder. A spring is fixedly connected to the inner top wall of the detection cylinder outside the push-button alarm, and a sealing block is fixedly connected to the lower end of the spring.

[0008] By adopting the above technical solution, when the ammonia storage tank leaks, the gas pressure inside the protective tank will increase, thereby squeezing the sealing block. The sealing block, affected by the gas pressure, compresses the spring and touches the push-button alarm, thus realizing the alarm function.

[0009] As a preferred technical solution of this application, the diameter of the sealing block is adapted to the inner diameter of the detection cylinder, and the initial position of the sealing block is located below the overflow hole.

[0010] By adopting the above technical solution, the sealing block can play a sealing role.

[0011] As a preferred technical solution of this application, the fixing unit includes two semi-circular fixing rings, which are fixedly connected together by fastening bolts, and the collecting airbag is located between the detection cylinder and the semi-circular fixing rings.

[0012] By adopting the above technical solution, the collecting airbag is fixedly sleeved onto the outer wall of the detection cylinder through the cooperation between the semi-circular fixing ring and the fastening bolt, thus achieving a tight connection between the collecting airbag and the detection cylinder.

[0013] As a preferred technical solution of this application, the top of the collecting airbag is provided with a valve core, and a protective cover is threaded onto the top of the valve core.

[0014] By adopting the above technical solution, the gaseous ammonia in the collection airbag can be discharged and collected by staff by setting the valve core, thus avoiding waste. The protective cover achieves physical sealing through threaded connection to prevent external contaminants from entering the valve core.

[0015] As a preferred technical solution of this application, the outer wall of the collecting airbag is provided with a number of telescopic folds.

[0016] By adopting the above technical solution, the volume of the telescopic pleats can be adjusted according to the increase or decrease of the amount collected in the collection bladder through the structural characteristics of folding or unfolding.

[0017] As a preferred technical solution of this application, the collecting airbag is made of polyurethane material, and the outer surface of the collecting airbag is coated with a brightly colored paint.

[0018] By adopting the above technical solution, polyurethane has high elasticity and impact resistance. The resulting collection airbag has good extensibility and can collect a large amount of gaseous ammonia, thus allowing sufficient reaction time for people to discover and repair it. Brightly colored paint is sprayed on the outer surface of the collection airbag to increase its visibility.

[0019] As a preferred embodiment of this application, the bottom of the protective tank is fixedly connected to a support base, and the top of the protective tank is fixedly connected to a lifting ring.

[0020] By adopting the above technical solution, it is convenient to transfer the protective tank by crane.

[0022] 1. In this utility model, through the cooperation between the detection cylinder and the alarm mechanism, an alarm can be issued immediately to remind people when the ammonia storage tank leaks.

[0023] 2. In this utility model, by setting a valve core, the gaseous ammonia in the collection airbag can be discharged and conveniently collected by the staff, avoiding waste. The protective cover achieves physical sealing through threaded connection to prevent external contaminants from entering the valve core. The telescopic pleats, through their folding or unfolding structural characteristics, can adjust their volume according to the increase or decrease of the amount collected in the collection airbag.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] like Figure 1 - Figure 4 As shown in the figure, this embodiment provides a high-pressure ammonia storage device, including an ammonia storage tank 1, a protective tank 2 around the outer ring of the ammonia storage tank 1, and a connecting block 3 for fixed connection between the ammonia storage tank 1 and the protective tank 2. A detection cylinder 4 is fixedly connected to the top of the protective tank 2, and an alarm mechanism 5 is provided inside the detection cylinder 4. Several overflow holes 6 are opened through the outer wall of the detection cylinder 4 along its circumference. A collection air bag 8 is fixedly attached to the outer wall of the detection cylinder 4 below the overflow holes 6 by a fixing unit 7. In use, through the cooperation between the detection cylinder 4 and the alarm mechanism 5, an alarm can be sounded immediately when the ammonia storage tank 1 leaks. The collection air bag 8 is fixedly attached to the outer wall of the detection cylinder 4 by the fixing unit 7, so that the leaked gaseous ammonia can flow into the collection air bag 8 through the overflow holes 6, so that the collection air bag 8 can collect the gaseous ammonia and prevent the gaseous ammonia from being directly released into the air, thus ensuring the personal safety of maintenance personnel.

[0033] In this embodiment, as Figure 2 and 3 As shown, the alarm mechanism 5 includes a push-button alarm 51, which is embedded in the top of the detection cylinder 4. A spring 52 is fixedly connected to the inner top wall of the detection cylinder 4 outside the push-button alarm 51. A sealing block 53 is fixedly connected to the lower end of the spring 52. When the ammonia storage tank 1 leaks, the air pressure in the protective tank 2 will increase, thereby squeezing the sealing block 53. The sealing block 53 is affected by the air pressure, compresses the spring 52, and touches the push-button alarm 51, thereby realizing the alarm function.

[0034] In this embodiment, as Figure 2 and 3As shown, the diameter of the sealing block 53 is matched with the inner diameter of the detection cylinder 4. The initial position of the sealing block 53 is located below the overflow hole 6, so that the sealing block 53 can play a sealing role during use.

[0035] In this embodiment, as Figure 3 and 4 As shown, the fixing unit 7 includes two semi-circular fixing rings 71, which are fixedly connected together by fastening bolts 72. The collecting airbag 8 is located between the detection cylinder 4 and the semi-circular fixing rings 71. In use, the collecting airbag 8 is fixedly sleeved on the outer wall of the detection cylinder 4 by the cooperation between the semi-circular fixing rings 71 and the fastening bolts 72, so as to achieve a tight connection between the collecting airbag 8 and the detection cylinder 4.

[0036] In this embodiment, as Figure 4 As shown, a valve core 10 is provided on the top of the collection airbag 8, and a protective cover 11 is threaded onto the top of the valve core 10. In use, by setting the valve core 10, the gaseous ammonia in the collection airbag 8 can be discharged and it is convenient for the staff to collect it, thus avoiding waste. The protective cover 11 achieves physical sealing through the threaded connection to prevent external pollutants from entering the valve core 10.

[0037] In this embodiment, as Figure 4 As shown, the outer wall of the collecting airbag 8 is provided with several telescopic pleats 9. When in use, the telescopic pleats 9 can adjust their volume according to the increase or decrease of the amount collected in the collecting airbag 8 through the structural characteristics of folding or unfolding.

[0038] In this embodiment, as Figure 1 As shown, the collecting airbag 8 is made of polyurethane material, and the outer surface of the collecting airbag 8 is coated with a bright color paint. When in use, polyurethane has high elasticity and impact resistance, so the collecting airbag 8 made of it has good extensibility. The bright color paint on the outer surface of the collecting airbag 8 is used to increase its visibility.

[0039] In this embodiment, as Figure 1 As shown, a support base 12 is fixedly connected to the bottom of the protective tank 2, and a lifting ring 13 is fixedly connected to the top of the protective tank 2, so that the protective tank 2 can be easily transferred by a crane during use.

[0040] The working principle of this utility model is as follows: When using the high-pressure ammonia storage device of this application, the cooperation between the detection cylinder 4 and the alarm mechanism 5 can immediately issue an alarm to remind people when the ammonia storage tank 1 leaks. The collection bag 8 is fixedly sleeved on the outer wall of the detection cylinder 4 through the cooperation between the semi-circular fixing ring 71 and the fastening bolt 72, so that the leaked gaseous ammonia can flow into the collection bag 8 through the overflow hole 6, so that the collection bag 8 can collect the gaseous ammonia and prevent the gaseous ammonia from being directly released into the air, thus ensuring the personal safety of maintenance personnel.
