Description

Technical Field

[0001] This utility model relates to the field of cooling tower protection, and in particular to a cooling tower spray tube bundle structure. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. Its cooling effect is achieved by the heat exchange between water and air flow to generate steam. The steam evaporates and carries away the heat, thus dissipating the waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0003] The working principle of a closed-circuit cooling tower is to place the heat exchange tube bundle inside the tower and cool it by exchanging heat with the fluid inside the tube bundle through water cooling and air cooling. Water cooling is generally achieved by circulating spraying coolant. Existing spray structures generally include multiple spray pipes that are welded together. Spray heads are installed on the spray pipes to spray the heat exchange tube bundle. However, assembling several spray pipes into a spray tube bundle by welding them together results in a large number of spray pipes, which requires a lot of installation work and has poor overall practical effect. Utility Model Content

An installation sleeve is detachably and fixedly fitted onto the outside of the main pipe, and the installation sleeve is fixedly connected to the main pipe by fasteners. A sealing gasket is provided on the contact surface between the inner wall of the installation sleeve and the main pipe. Multiple sets of water outlets are provided through the outer wall of the main pipe, and multiple sets of connecting pipes are fixedly and through the outside of the installation sleeve. The inner ends of the connecting pipes correspond one-to-one with and are connected to the water outlets. An insertion groove is provided on the outer end of the connecting pipe, and the outer side of the spray pipe is inserted into the insertion groove. A first connecting plate is fixedly connected to the outer side of the connecting pipe, and a second connecting plate that mates with the first connecting plate is fixedly fitted onto the outer side of the spray pipe. A fixing frame is fixedly fitted onto the outside of the installation sleeve, and a protruding protrusion is fixedly connected to the outer side of the fixing frame.

[0006] Preferably, the outer side of the main pipe is provided with a raised ridge in the longitudinal direction, and the inner wall of the mounting sleeve is provided with a sliding groove that slides and engages with the raised ridge in the longitudinal direction.

[0007] Preferably, a guide hole is fixedly connected to the outer side of the first connecting plate, and a guide rod that engages with the guide hole is provided through the outer side of the second connecting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model involves attaching an installation sleeve to the outside of the existing main pipeline and integrating a connecting pipe that matches the installation of multiple sets of spray pipes on the outside of the installation sleeve.

[0022] 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.

[0023] Reference Figure 1-5 A cooling tower spray pipe bundle structure includes a main pipe 1 and multiple sets of spray pipes 8. An installation sleeve 2 is detachably and fixedly fitted on the outside of the main pipe 1, and the installation sleeve 2 is fixedly connected to the main pipe 1 by fasteners 3. A sealing gasket 4 is provided on the contact surface between the inner wall of the installation sleeve 2 and the main pipe 1. Multiple sets of water outlets 5 are provided through the outer wall of the main pipe 1, and multiple sets of connecting pipes 6 are fixedly and through the outside of the installation sleeve 2. The inner end of the connecting pipe 6 corresponds to and is connected to the water outlet 5. A plug groove 12 is provided on the outer end of the connecting pipe 6, and the outside of the spray pipe 8 is plugged into the plug groove 12. A first connecting plate 7 is fixedly connected to the outer side of the connecting pipe 6, and a second connecting plate 9 that connects to the first connecting plate 7 is fixedly fitted on the outside of the spray pipe 8. A fixing frame 10 is fixedly fitted on the outside of the installation sleeve 2, and a protruding protrusion 11 is fixedly connected to the outside of the fixing frame 10.

[0024] The main pipe 1 has a longitudinally protruding ridge 101 on its outer side, and the inner wall of the mounting sleeve 2 has a longitudinally protruding groove 201 that slides and engages with the protruding ridge 101. The outer side of the first connecting plate 7 is fixedly connected to a guide hole 701, and the outer side of the second connecting plate 9 is provided with a guide rod 901 that engages with the guide hole 701. The upper end of the second connecting plate 9 is provided with a limit hole 902, and the upper end of the protrusion 11 is movably inserted with a limit pin 1101, which is movably inserted into the limit hole 902. The upper end of the limit pin 1101 is fixedly connected to a handle 1102, and the bottom of the handle 1102 is connected to the upper end of the protrusion 11 by a spring 1103. The spring 1103 is in a retracted state by default.

[0025] Based on the above structural design, when using this device, the operator will align the sliding groove 201 on the inner wall of the mounting sleeve 2 with the protruding ridge 101 on the outer wall of the main pipe 1, and insert the mounting sleeve 2 longitudinally so that it fits onto the outside of the main pipe 1. Due to the limiting and guiding effect of the protruding ridge 101 and the sliding groove 201, after the mounting sleeve 2 is fitted onto the main pipe 1, the connecting pipe 6 on its outer side can be connected to the outlet 5 on the outside of the main pipe 1. In addition, with the sealing gasket 4 on the contact surface between the main pipe 1 and the mounting sleeve 2, the sealing effect of the connection is increased, and water leakage from the outlet 5 is prevented. After installation, the main pipe 1 and the mounting sleeve 2 are fixed with fasteners 3. Subsequently, the staff connected the spray pipe 8 to the outside of the connecting pipe 6. The right end of the spray pipe 8 was inserted into the insertion groove 12 on the outer wall of the connecting pipe 6. The two were inserted together. The rubber gasket on the inner wall of the insertion groove 12 could increase the sealing effect of the connection between the two. During the process of inserting the spray pipe 8 into the insertion groove 12, the guide rod 901 on the outside of the second connecting plate 9 on the outside of the spray pipe 8 was inserted into the guide hole 701 on the outside of the first connecting plate 7. The two guided the spray pipe 8 and the connecting pipe 6 to be precisely connected. The limiting hole 902 at the upper end of the second connecting plate 9 could be aligned with the limiting pin 1101 that penetrated the upper end of the protrusion 11. Furthermore, during the process of connecting the spray pipe 8 to the connecting pipe 6, the operator holds the handle 1102 beforehand and pulls the limiting pin 1101 upward, simultaneously stretching the spring 1103. After the spray pipe 8 is connected to the connecting pipe 6, the operator releases the handle 1102. At this time, the handle 1102, under the elastic contraction of the spring 1103, drives the limiting pin 1101 downward to precisely engage in the limiting hole 902 at the upper end of the second connecting plate 9, thus limiting and fixing the connection between the first connecting plate 7 and the second connecting plate 9, ensuring the stability of the spray pipe 8 during use. The same principle applies to subsequent disassembly. Compared with traditional welding methods, the disassembly and assembly of this device is very simple, convenient, and practical.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
