Description

Technical Field

[0001] The utility model relates to the technical field of evaporative air coolers, in particular to a novel structure for controlling the concentration multiple of circulating water in evaporative air coolers. Background Art

[0002] In the application field of evaporative air coolers, the concentration ratio of circulating water is an important performance indicator. During the evaporation and condensation process of circulating water in the air cooler, it will continue to concentrate, resulting in a gradual increase in the concentration of dissolved substances in the water. If the concentration ratio of circulating water is too high, it will not only affect the cooling effect of the air cooler, but may also cause corrosion and blockage to the equipment, and even affect the normal operation of the entire system. Therefore, how to effectively increase the concentration ratio of circulating water while ensuring the stable operation of the system has become an urgent problem to be solved in the field of evaporative air cooler technology.

[0003] The traditional evaporative air cooler structure has certain limitations in controlling the concentration multiple of circulating water. On the one hand, since the circulating water is prone to carry waste residue and impurities during the spraying process, these impurities will be deposited inside the air cooler, affecting the cooling effect; on the other hand, the traditional control system is often unable to accurately monitor the conductivity changes of the circulating water, and thus cannot adjust the concentration multiple of the circulating water in time. Utility Model Content

[0004] The purpose of the utility model is to provide a new structure for controlling the concentration multiple of circulating water in an evaporative air cooler, so as to solve the problem that the traditional evaporative air cooler structure proposed in the above background technology has certain limitations in controlling the concentration multiple of circulating water. On the one hand, since the circulating water is easy to carry waste residue and impurities during the spraying process, these impurities will be deposited inside the air cooler, affecting the cooling effect; on the other hand, the traditional control system is often unable to accurately monitor the conductivity change of the circulating water, and thus cannot adjust the concentration multiple of the circulating water in time.

[0005] To achieve the above-mentioned purpose, the utility model provides a novel structure for controlling the concentration multiple of circulating water of an evaporative air cooler, comprising an air cooler, a spray pump is installed at the bottom of the air cooler, the output end of the spray pump is connected to a water outlet pipe, a conductivity sensor is installed on the water outlet pipe, a water pan is installed at the bottom of the air cooler, a water replenishment float valve is installed on the upper part of the water pan, a drain pipe is connected to one side of the bottom of the water pan, and an electric valve is installed on the drain pipe.

[0006] Preferably, a waste residue collection trough is installed at the bottom bend of the water outlet pipe.

[0007] Preferably, the waste residue collection tank comprises a horizontally arranged cylinder, the top of the cylinder is vertically connected to a vertical pipe, the top of the vertical pipe is connected to a water outlet pipe, a rotating shaft is installed inside the cylinder, and a spiral push piece is installed on the outer wall of the rotating shaft.

[0008] Preferably, a discharge port is provided at the bottom of one end of the cylinder.

[0009] Preferably, one end of the rotating shaft is driven to rotate by a motor.

[0011] Preferably, the input end of the electric valve is connected to an external control system, and the output end of the conductivity sensor is connected to the external control system.

[0012] Preferably, the water outlet pipe is arranged in multiple sections, and each section is connected by a rubber hose.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the novel structure for controlling the concentration multiple of circulating water for evaporative air cooler, the conductivity sensor is installed on the outlet pipe to monitor the conductivity change of circulating water in real time, so as to accurately grasp the concentration degree of circulating water. When the conductivity exceeds the preset threshold, the external control system automatically starts the electric valve to discharge highly concentrated water, and automatically replenishes fresh water through the water replenishment float valve to achieve precise control of the concentration multiple of circulating water. Through the combined action of the conductivity sensor and the electric valve, the system can automatically adjust the concentration multiple of circulating water, avoiding equipment corrosion and blockage caused by excessive concentration multiple of circulating water. At the same time, the introduction of the waste residue collection tank also reduces the risk of system failure due to waste residue accumulation, and further improves the stability of the system. By increasing the concentration multiple of circulating water, the use of fresh water and the discharge of wastewater are reduced, which meets the requirements of energy conservation and environmental protection. In addition, the introduction of the waste residue collection tank also reduces the cost of waste residue treatment, further improving the economic benefits of the system.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a novel structure for controlling the concentration multiple of circulating water in an evaporative air cooler, such as Figure 1-Figure 3 As shown, it includes an air cooler 1, a spray pump 2 is installed at the bottom of the air cooler 1, and the output end of the spray pump 2 is connected to a water outlet pipe 21, and a conductivity sensor 3 is installed on the water outlet pipe 21. A water tray 5 is installed at the bottom of the air cooler 1, and a water replenishment float valve 6 is installed on the upper part of the water tray 5. A drain pipe is connected to one side of the bottom of the water tray 5, and an electric valve 4 is installed on the drain pipe. Through the conductivity sensor 3 installed on the water outlet pipe 21, the system can monitor the conductivity change of the circulating water in real time, so as to accurately grasp the concentration degree of the circulating water. This function enables the system to automatically adjust the concentration multiple of the circulating water according to the actual state of the circulating water, avoid equipment corrosion and blockage caused by excessive concentration multiples, and also reduce unnecessary energy consumption and water resource waste. The water replenishment float valve 6 on the upper part of the water tray 5 can be automatically opened or closed according to the height of the water level in the water tray, ensuring that a suitable water level is always maintained in the water tray. When the water level is lower than the set value, the float valve will automatically open to replenish fresh water; when the water level is too high, the float valve will close and stop replenishing water. At the same time, the electric valve 4 on the drain pipe can automatically open the drain according to the system requirements or the signal of the conductivity sensor, discharge highly concentrated water, and ensure the quality of the circulating water. Through the coordinated work of the conductivity sensor 3, the water replenishment float valve 6 and the electric valve 4, the system can realize the automatic adjustment and stable control of the concentration multiple of the circulating water. This not only avoids equipment failure and performance degradation caused by excessive concentration multiples of circulating water, but also improves the overall stability and reliability of the system, reduces operation and maintenance costs and downtime. By accurately controlling the concentration multiple of circulating water and the automatic water replenishment and drainage function, the utility model effectively reduces the use of fresh water and the discharge of wastewater, reduces energy consumption and water resource consumption, and meets the requirements of energy conservation and environmental protection. This is of great significance for improving the economic benefits and social responsibility of enterprises.

[0022] In this embodiment, a waste residue collection tank 7 is installed at the bottom bend of the water outlet pipe 21 for collecting waste residue.

[0023] Specifically, the waste residue collecting tank 7 includes a horizontally arranged cylinder 71, the top of which is vertically connected to a vertical pipe 75, the top of which is connected to the water outlet pipe 21, a rotating shaft 72 is installed inside the cylinder 71, and a spiral push piece 73 is installed on the outer wall of the rotating shaft.

[0024] Furthermore, a discharge port 711 is provided at the bottom of one end of the cylinder 71 to facilitate the discharge of waste residues.

[0025] Furthermore, one end of the rotating shaft 72 is driven to rotate by the motor 74, so that the rotating shaft 72 rotates and drives the spiral push piece 73 to push the material.

[0026] Furthermore, the water outlet pipe 21 is vertically arranged, and the top end is connected to the spraying device of the air cooler 1, so as to facilitate the circulation of the circulating water and then spraying.

[0027] Furthermore, the input end of the electric valve 4 is connected to the external control system, and the output end of the conductivity sensor 3 is connected to the external control system. The signal of the conductivity sensor 3 is received by the background control system, and the opening and closing actions of the electric valve 4 are controlled after judgment.

[0028] Furthermore, the water outlet pipe 21 is provided in multiple sections, and each section is connected by a rubber hose to ensure the flexibility of the water outlet pipe 21.

[0029] When the novel structure for controlling the concentration multiple of circulating water for evaporative air cooler of the utility model is used, firstly, after the spray pump 2 is started, circulating water is drawn from the water pan 5, and the circulating water is transported to the spray device of the air cooler 1 through the vertically arranged water outlet pipe 21 (multiple sections are arranged, and each section is connected by a rubber hose). This arrangement ensures that the circulating water can be flexibly transported and evenly sprayed on the air cooler 1 for heat exchange.

[0030] The conductivity sensor 3 monitors the conductivity change of the circulating water in the water outlet pipe 21 in real time, so as to accurately grasp the concentration degree of the circulating water.

[0031] The external control system receives the signal sent by the conductivity sensor 3 and makes a judgment based on a preset threshold value. When the conductivity exceeds the set threshold value, the control system will issue an instruction to start the electric valve 4 to perform drainage operation to reduce the concentration multiple of the circulating water.

[0032] The circulating water may carry waste residue and impurities during the spraying process. When the waste residue flows through the outlet pipe 21, it will enter the waste residue collection tank 7. The waste residue collection tank 7 is composed of a horizontally arranged cylinder 71 and a vertical pipe 75 connected vertically at the top. The vertical pipe 75 is connected to the outlet pipe 21 to collect the waste residue.

[0033] The motor 74 drives the rotating shaft 72 to rotate, thereby driving the spiral push piece 73 to rotate inside the cylinder 71. The rotation of the spiral push piece 73 pushes the waste slag to the discharge port 711 at one end of the cylinder 71, thereby realizing automatic discharge of the waste slag.

[0034] When the water level in the water pan 5 is lower than the water level set by the water replenishment float valve 6, the float valve will automatically open to allow fresh water to enter the water pan 5 to replenish the circulating water. When the water level reaches the set value, the float valve closes and stops replenishing water. This process ensures that a suitable water level is always maintained in the water pan 5.

[0035] Finally, it should be noted that the electric valve 4, conductivity sensor 3, etc. in this embodiment, the electronic components in the above parts are all universal standard parts or parts known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the field.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
