Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an energy-saving cooling tower outlet water main filter. Background Technology

[0002] Cooling towers use water as a circulating coolant. Through contact between water and air, evaporation, convection, and radiation heat dissipation are generated, transferring waste heat generated by industrial production or refrigeration systems to the atmosphere, ensuring the normal operation of the system. They are mainly used for waste heat treatment in industrial and air conditioning systems. They are usually cylindrical in shape with a spray system on top. Water is evenly sprayed onto the heat dissipation plate through water pipes. Air is accelerated by a fan to carry away heat, and the cooling tower outputs water through the main outlet pipe.

[0003] Existing energy-saving cooling towers make it difficult to control water quality when transporting water through the main outlet pipe, and the use of filters is not suitable for transporting large volumes of water; therefore, they do not meet the current requirements. In response, we propose an energy-saving cooling tower outlet main pipe filter. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1 and Figure 2 This utility model provides an embodiment of an energy-saving cooling tower outlet main pipe filter, including a filter installation mechanism 1. A filter unit 3 is installed inside the filter installation mechanism 1. The filter installation mechanism 1 includes a linear filter shell 101. The two ends of the linear filter shell 101 are respectively provided with an inlet 102 and an outlet 103. A filter installation cavity 105 is provided on the inner side of the middle part of the linear filter shell 101. A drain pipe 104 is fixedly installed at the bottom end of the linear filter shell 101. A plurality of filter installation cavities 105 are provided at the upper end of the drain pipe 104. The water flow direction is from the inner side of the filter sleeve 301 to the outer side of the filter sleeve 301. Thus, the filter sleeve 301 can effectively avoid deformation due to water flow impact under the protection of the linear filter shell 101.

[0022] Please see Figures 2 to 4 The filter unit 3 includes a filter sleeve 301. A flow guide gap is provided between the linear filter shell 101 and the filter sleeve 301. A water inlet 302 is provided on the left side of the filter sleeve 301. The water inlet 102 and the water inlet 302 are coaxial. A contact sealing ring 303 is fixedly provided on the side of the water inlet 302. The filter sleeve 301 is set inside the filter mounting cavity 105 and is in close contact with the inner wall of the linear filter shell 101 through the contact sealing ring 303. A plurality of filter micro-holes 304 are provided on the right side surface of the filter sleeve 301. The flow guide gap can effectively meet the requirement that the multiple filter micro-holes 304 fully participate in the filtration operation and effectively avoid the local blockage of the filter micro-holes 304.

[0023] Multiple filter mounting chambers 105 are arranged circumferentially relative to the axis of the drain pipe 104. The bottom end of the filter sleeve 301 is inserted into the multiple filter mounting chambers 105. The bottom end of the filter sleeve 301 is connected to the drain pipe 104 through the multiple filter mounting chambers 105. The filter mounting chambers 105 can be used to position the filter sleeve 301 and prevent the filter sleeve 301 from axially deflecting when it is impacted by water flow.

[0024] Please see Figures 1 to 3 The upper end of the filter installation mechanism 1 is equipped with a connecting exhaust mechanism 2, which includes a sealing cover 201. The upper end of the linear filter housing 101 is fixedly connected to the sealing cover 201. An exhaust pipe 202 is fixedly provided in the middle of the upper surface of the sealing cover 201. A connecting pressure ring 203 is installed on the lower surface of the sealing cover 201. Multiple locking knobs 204 are installed on the lower surface of the connecting pressure ring 203. The multiple locking knobs 204 are arranged circumferentially along the axis of the connecting pressure ring 203. The upper end of the locking knobs 204 passes through... The connecting pressure ring 203 is connected to the sealing cover 201 by threads. The upper end of the filter sleeve 301 is inserted between the sealing cover 201 and the connecting pressure ring 203. The sealing cover 201 and the connecting pressure ring 203 are fixedly connected by multiple locking knobs 204. By disassembling the sealing cover 201 from the linear filter housing 101, the filter sleeve 301 can be separated from the multiple filter mounting cavities 105 by the connecting pressure ring 203 and multiple locking knobs 204, so as to realize the quick disassembly and replacement of the filter sleeve 301.

[0025] Please see Figure 2 The inlet 102 and outlet 103, as well as the drain pipe 104 and vent pipe 202, are all connected through the filter installation cavity 105. The upper end of the vent pipe 202 is equipped with an vent valve, and the lower end of the drain pipe 104 is equipped with a drain valve. The vent pipe 202 facilitates the venting of air into the filter installation cavity 105, and the drain pipe 104 facilitates the periodic drainage of air into the filter installation cavity 105.

[0026] In summary, by fixing the left end of the linear filter shell 101 to the main outlet pipe of the energy-saving cooling tower, water is injected into the linear filter shell 101 through the inlet 102. The filter sleeve 301 then receives water through the inlet 302 and filters it simultaneously through multiple micro-filtration holes 304. The water is then output through the outlet 103. When the filter sleeve 301 filters the water, the water flow direction is from the inside of the filter sleeve 301 to the outside of the filter sleeve 301. Thus, the filter sleeve 301 can effectively avoid deformation due to water flow impact under the protection of the linear filter shell 101.

[0027] A contact sealing ring 303 is fixedly provided on the side of the water inlet 302, so that the filter sleeve 301 and the inner wall of the linear filter shell 101 are connected through the contact sealing ring 303. A flow guiding gap is provided between the linear filter shell 101 and the filter sleeve 301. The flow guiding gap can effectively meet the full participation of multiple filter micro-holes 304 in the filtration operation, effectively avoiding the local blockage of the filter micro-holes 304. By disassembling the sealing cover 201 and the linear filter shell 101, the filter sleeve 301 can be separated from the multiple filter mounting cavities 105 by connecting the pressure ring 203 and multiple locking knobs 204, realizing the quick disassembly and replacement of the filter sleeve 301.

[0028] The exhaust pipe 202 facilitates the venting of air into the filter mounting cavity 105, and the drain pipe 104 allows for periodic drainage of the filter mounting cavity 105. The upper end of the filter sleeve 301 is inserted between the sealing cover 201 and the connecting pressure ring 203, and the bottom end of the filter sleeve 301 is connected to the drain pipe 104 through multiple filter mounting cavities 105. Thus, the filter sleeve 301 can be positioned through the filter mounting cavity 105 to prevent the filter sleeve 301 from axially deflecting when subjected to water flow impact.
