Technical Field

[0001] The utility model relates to the technical field of evaporative condensers, in particular to an anti-clogging nozzle for an evaporative condenser. Background Art

[0002] The cooling circulating water evaporates in the condensing coil, and the gaseous ammonia condenses into liquid in the condensing coil, so it is called an evaporative condenser. The high-intensity evaporation makes the evaporative condenser more prone to scaling than other types of condensers. There is currently no ideal descaling method, and severely scaled evaporative condensers lose their power-saving advantages.

[0003] Part of the scale is washed into the sump by the water flow, and the scale is transported with the circulating water and finally sprayed out through the nozzle. However, the scale can easily cause the nozzle to be blocked, which will cause the nozzle to fail to work properly and require staff to disassemble and clean it, which is very inconvenient to use. For this reason, the present application proposes an anti-blocking nozzle for an evaporative condenser. Utility Model Content

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-3 As shown, the embodiment of the utility model provides an anti-clogging nozzle for an evaporative condenser, comprising:

[0021] Nozzle 1;

[0022] Anti-blocking component; the anti-blocking component includes a connecting pipe 2 installed on the nozzle 1, the upper end of the connecting pipe 2 is a first inclined surface, a mounting groove 10 is provided on the first inclined surface, a filter screen 11 is placed in the mounting groove 10, the filter screen 11 is inclined, the side of the water supply pipe 3 opposite to the connecting pipe 2 is a second inclined surface, the second inclined surface is matched with the first inclined surface, so that the filter screen 11 can be limited so that it will not separate from the mounting groove 10; wherein, the filter screen 11 is a stainless steel mesh, a nylon mesh or the like can be fixed on its surface, and is used to effectively filter scale, the stainless steel filter screen 11 has a certain supporting capacity and is not easy to deform, and scale can be filtered through the filter screen 11, effectively preventing the nozzle 1 from being blocked.

[0023] A detachable water supply pipe 3 is installed at the upper end of the connecting pipe 2. The outer sleeve of the water supply pipe 3 is provided with a sealed and fixed mounting pipe 7. The outer wall of the mounting pipe 7 is provided with an external thread 8. The outer rotation of the connecting pipe 2 is connected with a rotating tube 6. The inner wall of the rotating tube 6 is provided with an internal thread 9. The mounting tube 7 extends into the rotating tube 6. The external thread 8 is meshed with the internal thread 9. The mounting tube 7 is put on the connecting pipe 2 and moved downward until the mounting tube 7 extends into the rotating tube 6. Then, the rotating tube 6 is rotated to make the external thread 8 mesh with the internal thread 9 until it cannot be rotated. In this way, the water supply pipe 3 and the connecting pipe 2 can be installed and moved. The threaded connection method is simple and stable, and it is also convenient to disassemble so that the filter 11 can be cleaned or replaced.

[0024] A support ring is fixed on one end of the rotating tube 6 facing the nozzle 1, and the support ring is rotatably connected to the connecting tube 2. A sealing ring is fixed on the support ring. The external thread 8 is meshed with the internal thread 9 to engage with the mounting tube 7 and the rotating tube 6. After the mounting tube 7 and the rotating tube 6 are installed, the mounting tube 7 and the sealing ring are abutted against each other. In this way, the sealing of the mounting tube 7 and the rotating tube 6 after installation can be guaranteed.

[0025] A short tube 4 tangent to the upper end face of the filter 11 is installed on the water supply pipe 3, and the inner wall below the short tube 4 is tangent to the upper end face of the filter 11 to ensure that the filter 11 can effectively filter the circulating water; a pressure solenoid valve assembly 5 is installed in the short tube 4, and the filter 11 is blocked, resulting in an increase in water pressure in the short tube 4. The pressure solenoid valve assembly 5 is composed of a solenoid valve and a water pressure sensor. The water pressure sensor is a pressure sensor that is more commonly used in industrial practice. The model of the water pressure sensor is ELE-801; the water pressure sensor is electrically connected to the solenoid valve, and a suitable solenoid valve can be purchased on the market; the pressure solenoid valve assembly 5 can be opened to discharge water, and the water flow flushing the filter 11 can clean the filter 11.

[0026] When the filter screen 11 is blocked, the amount of circulating water passing through the filter screen 11 decreases, and the circulating pump continues to work, causing the water pressure at the short pipe 4 to increase. When the water pressure reaches the pressure value set by the water pressure sensor, the water pressure sensor will transmit the model to the controller, and the controller controls the solenoid valve to open, and the clean water is discharged through the short pipe 4. At this time, the filter screen 11 plays a guiding role, allowing the circulating water to flow to the short pipe 4. After being flushed by the circulating water, the filter screen 11 can be cleaned;

[0027] When the filter 11 is no longer blocked, the circulating water flows through the filter 11 and the short tube 4. At this time, the pressure value detected by the water pressure sensor decreases, and the solenoid valve is controlled to close, thereby achieving self-cleaning of the filter 11 and preventing the nozzle 1 from being blocked.

[0028] As mentioned above, the water pressure sensor transmits signals to the controller to control the switch of the solenoid valve, which is the prior art. It is similar to the alarm when the elevator is overweight. The principles are similar and both are the prior art of PLC.

[0029] Finally, it should be noted that the above 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 with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
