Description

Technical Field

[0001] The utility model relates to the technical field of evaporative condensers, and particularly relates to an anti-scaling evaporative condenser. Background Technique

[0002] An evaporative condenser is a heat exchange device commonly used for cooling in cold storages. It passes the hot substance to be condensed through a coil pipe, and then sprays cold water onto the coil pipe to enable heat exchange between the hot substance and the cold water, thereby achieving the condensation function. However, during the use of the existing evaporative condensers, since the cold water used for spraying is usually tap water, which contains a large amount of calcium and magnesium ions, the water heated by the hot substance will inevitably form scale on the coil pipe, which will affect the heat exchange of the condenser over time.

[0003] Therefore, we design an anti-scaling evaporative condenser here. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 - 3, in this embodiment: an anti-scaling evaporative condenser, including a box body 1, a medicine feeding port is arranged on the side of the box body 1, an inclined chute 2 is installed at the medicine feeding port, the scale inhibitor is put into the inclined chute 2, and the scale inhibitor can slide down along the inclined chute 2 into the interior of the box body 1. A cover plate 3 is rotatably installed at the entrance of the inclined chute 2. When not adding medicine, the cover plate 3 can cover the entrance of the inclined chute 2 to prevent some garbage from entering the box body 1 from the medicine feeding port and causing equipment blockage. A cross plate 4 is installed on the inner side of the box body 1. The cross plate 4 is located below the medicine feeding port. A driving stirring shaft 5 is rotatably installed at the central position of the cross of the cross plate 4. Driven stirring shafts 6 are rotatably installed at the middle positions of the four cross legs of the cross plate 4. Stirring blades 7 are installed at the bottoms of the driving stirring shaft 5 and the four driven stirring shafts 6;

[0019] Four sprockets are installed at the top of the driving stirring shaft 5, and one sprocket is installed at the top of each of the four driven stirring shafts 6. The driving stirring shaft 5 is respectively connected with the four driven stirring shafts 6 through chains 8. A waterproof housing 9 is installed at the top of the cross plate 4. All the sprockets and chains 8 are located inside the waterproof housing 9. A motor 10 is installed at the central position inside the waterproof housing 9. The output shaft of the motor 10 is connected with the driving stirring shaft 5. After the scale inhibitor enters the water in the box body 1, the motor 10 can be used to drive the driving stirring shaft 5 to rotate, and then through the transmission of the chain 8, drive the four driven stirring shafts 6 to rotate together, so as to control the stirring blades 7 to stir the water body and accelerate the mixing of water and the scale inhibitor. The switch of the motor 10 can be set beside the inclined chute 2, which is convenient for workers to start the motor 10 immediately after adding medicine.

[0020] A water filling port 1-1 and a drain port 1-2 are arranged on the side of the box body 1. The water filling port 1-1 is at the same height as the medicine feeding port on the side of the box body 1 and is located beside the medicine feeding port. The drain port 1-2 is located at the bottom of the box body 1. A solenoid valve 11 is installed on the drain port 1-2. When this condenser is in use, the water filling port 1-1 is connected to a water pipe for filling water at the bottom of the box body 1. When filling water, the water level height should be lower than the height of the medicine feeding port on the side of the box body 1. When it is necessary to drain the water in the box body 1, just open the solenoid valve 11.

[0021] Inside the box body 1, a coil pipe 13 and a shunt pipe 14 are installed. A row of spray pipes 15 are installed on the shunt pipe 14. The coil pipe 13 is located above the chemical feeding port on the side of the box body 1. Both the shunt pipe 14 and the spray pipes 15 are located directly above the coil pipe 13. At the bottom of each spray pipe 15, a row of nozzles 16 with downward nozzles are installed. The liquid inlet end 13-1 and the liquid outlet end 13-2 of the coil pipe 13, and the water inlet 14-1 of the shunt pipe 14 are all arranged outside the box body 1. A water pump 17 is installed on the outer side of the box body 1. The water inlet end of the water pump 17 is connected to the bottom of the box body 1 through a pipeline, and the water outlet end of the water pump 17 is connected to the water inlet 14-1 of the shunt pipe 14 through a pipeline. When this condenser is in use, the water at the bottom of the box body 1 can be pumped into the shunt pipe 14 through the water pump 17, then sprayed onto the coil pipe 13 through the nozzles 16 at the bottom of the spray pipes 15, and finally the water falls back to the bottom of the box body 1 under the action of gravity to form a cycle. During this process, the hot substance to be condensed is passed into the coil pipe 13, and the hot substance in the coil pipe 13 exchanges heat with the sprayed water on the surface of the coil pipe 13, so as to achieve the condensation effect.

[0022] Ventilation windows are opened on the four side walls of the box body 1. All the ventilation windows are located above the chemical feeding port on the side of the box body 1. Ventilation louvers 12 are installed on each ventilation window. Two fans 18 are installed on the top of the box body 1.

[0023] The working principle and usage process of the present utility model: When this anti-scaling evaporative condenser is in use, first add an appropriate amount of water into the box body 1, then open the cover plate 3, pour an appropriate amount of scale inhibitor into the inclined chute 2, and then start the motor 10. The motor 10 directly drives the active stirring shaft 5 to rotate, and then through chain drive, drives the four driven stirring shafts 6 to rotate, thereby controlling the stirring blades 7 to rotate and stir the water body at the bottom of the box body 1, so that the water and the scale inhibitor are quickly mixed. After a period of time, turn off the motor 10, start the water pump 17 and the fans 18, and finally pass the hot substance to be condensed into the coil pipe 13 for condensation.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
