Description

Technical Field

[0001] This utility model relates to a series of auxiliary components for cooling towers, specifically to an automatic cleaning filter barrel for cooling towers. Background Technology

[0002] In existing open cooling tower cooling water circulation systems, the common water filtration method is screen filtration, which requires manual cleaning or the purchase of separate water filtration equipment.

[0003] The above two forms have the following problems:

[0004] (1) Using ordinary filters that require manual cleaning means that the water quality cannot be monitored in real time. The machine will only be stopped for manual cleaning when the water quality changes significantly. This passive water treatment method is labor-intensive, which can easily lead to damage to the water pump or valve and affect the performance of the cooling tower.

[0005] (2) Purchasing a separate water filtration device is costly and often cannot be well adapted to the cooling tower. It is also large in size and takes up unnecessary space. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic cleaning filter barrel for cooling towers. It adopts a self-cleaning system and integrates it into the cooling tower, which saves costs and space. Furthermore, it is combined with the cooling tower control system. When the cooling tower's water quality monitoring system detects water quality problems, it can directly control the servo motor to control the rotation speed of the filter barrel, thereby performing real-time water quality treatment.

[0009] Preferably, it also includes a cleaning drain pipe, and the barrel body also has a cleaning water pipe. The cleaning drain pipe is fixedly installed inside the barrel body and located outside the filter cylinder body.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0019] like Figure 1 , Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of an automatic cleaning filter barrel for a cooling tower according to the present invention. Figure 2 for Figure 1 Exploded view; An automatic cleaning filter tank for a cooling tower, the automatic cleaning filter tank includes a tank body 10, a drain bottom plate 20, a filter cover 30, a water-sealing top cover 40, and a servo motor 50. The drain bottom plate 20 is fixedly connected to the bottom end of the tank body 10. The filter cover 30 is placed inside the tank body 10 and located above the drain bottom plate 20. The water-sealing top cover 40 is fixedly connected to the top end of the tank body 10. The filter cover 30 includes a filter cylinder body 31, a rotating connecting frame (not shown), a rotating shaft 32, and a water-baffle rim 33. The water-baffle rim 33 is fixedly connected to the outer side of the top end of the filter cylinder body 31. The rotating connecting frame is placed on the filter cylinder body. The body 31 is inside and fixedly connected to the filter cylinder 31. The rotating shaft 32 is located at the center of the rotating connecting frame and is fixedly connected to the rotating connecting frame. The rotating shaft 32 passes through the center of the water-sealing top cover 40 and is fixedly connected to the servo motor 50. The servo motor 50 is electrically connected to the control system in the cooling tower. The barrel 10 has a water inlet 11 and a water outlet 12. The water inlet 11 and the water outlet 12 are connected to the cooling water pipe of the cooling tower. The vertical height of the water inlet 11 is higher than the vertical height of the baffle plate edge 33. The water inlet 11 is located at the upper part of the barrel 10, and the water outlet 12 is located at the lower part of the barrel 10.

[0020] This utility model discloses an automatic cleaning filter barrel for a cooling tower, which is integrated with the cooling tower. Its inlet and outlet water are connected to the cooling tower's water pipe network, and it is controlled by the cooling tower's control system. The control system monitors the water quality of the water pipe network in real time to control the automatic cleaning filter barrel, thereby performing filtration. Cooling water from the cooling tower's water pipe network enters the barrel through the inlet. Inside the barrel, the water is blocked by a baffle plate, preventing water from flowing back in. Therefore, most of the cooling water enters the filter housing, which is hollow. The filter housing rotates under the drive of a rotating connecting frame, which in turn rotates under the drive of a rotating shaft driven by a servo motor. The servo motor's speed is controlled by the cooling tower's control system. When the control system detects poor water quality, it outputs a control signal to the servo motor, causing the servo motor to output a higher speed, thus driving the filter housing to rotate rapidly in multiple stages. This creates centrifugal force within the filter housing, causing the cooling water to flow through the filter housing and into the space between the barrel and the filter housing, ultimately exiting through the outlet into the cooling tower's water pipe network. Impurities are blocked and remain in the filter cylinder. When cleaning, they are left in the bottom drain plate and discharged through the drain plate, which has a drain outlet.

[0021] To facilitate faster collection and discharge of impurities, a cleaning drain pipe 60 is preferably included. The barrel 10 also has a cleaning water pipe 13, which is fixedly installed inside the barrel 10 and located outside the filter cylinder 31. The water inlet of the cleaning drain pipe 60 is connected to an external water pipe through the cleaning water pipe 13.

[0022] After the filter cylinder stops rotating and filters, clean cleaning water is sprayed through the cleaning pipe to knock down the impurities attached to the filter cylinder, causing the impurities to flow to the bottom and be discharged in time.

[0023] To ensure more uniform and thorough filtration of cooling water, preferably, the filter cylinder 31 has multiple filter holes 34 of equal and uniform diameter.

[0024] By setting multiple filter holes of equal size and evenly distributed on the filter cylinder, the cooling water inside the filter cylinder can be filtered. Impurities in the cooling water cannot pass through the filter holes, but can only adhere to the area around the filter holes or flow to the bottom.

[0025] Regarding how the cleaning pipe achieves the cleaning of impurities on the filter cylinder, preferably, the cleaning pipe 60 includes a main water inlet pipe 61, a branch pipe 62, and multiple nozzles 63. The water inlet end of the main water inlet pipe 61 is placed inside the cleaning water pipe 13, and the water outlet end of the main water inlet pipe 61 is connected to the water inlet of the branch pipe 62. The branch pipe 62 has multiple water spray outlets, and the nozzles 63 are installed in the water spray outlets.

[0026] The main inlet pipe is connected to clean water from the outside through a cleaning water pipe. The clean water from the outside enters the main inlet pipe and then enters the branch pipe. It is then distributed to the nozzles through multiple spray outlets and sprayed onto the filter holes of the filter cylinder, thereby cleaning the impurities inside the filter cylinder.

[0027] This utility model patent employs a self-cleaning system integrated into the cooling tower, which has the following advantages compared to traditional water filtration methods:

[0028] 1) The self-cleaning filter cartridge is directly integrated into the cooling tower piping. This results in high material utilization, saving materials, space, and reducing costs.

[0029] 2) The existing water quality monitoring system of the cooling tower can directly feed back signals to the servo motor of the self-cleaning filter. The servo motor then determines the speed of the filter based on the signal strength, thereby processing the water quality in real time to ensure the stability of the water quality.

[0030] 3) The water treatment process does not require shutdown or separate maintenance personnel, saving manpower;

[0031] 4) Good structural strength, high reliability, high efficiency, and further reduced cost;

[0032] 5) The installation structure is simple, easy to store, handle, transport and install, and does not take up extra space;

[0033] 6) It is compatible with various equipment such as communication, power distribution, network, and IDC cabinets, and is more suitable for IDC and communication rooms with wide distribution, modular structure and large configuration changes.

[0034] Compared with existing technologies, the advantages of this utility model are as follows: By setting a filter cover inside the barrel, water entering the barrel is filtered inside the filter cover, pure water is filtered out from the filter cover and transported out through the water outlet of the barrel, while impurities remain inside the filter cover and are discharged through the drain plate; by setting a servo motor electrically connected to the cooling tower control system, the cooling tower monitors the water quality and controls the servo motor, further controlling the rotation speed of the filter cover, thereby controlling the amount of filtered water; by setting a cleaning drain pipe, impurities stuck to the filter holes are rinsed, so that the impurities are collected on the drain plate for easy discharge.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
