Description

Technical Field

[0001] This utility model relates to the field of cooling towers, and in particular to a variable flow nozzle for cooling towers. Background Technology

[0002] A cooling tower is a device used to reduce the heat generated in industrial processes. Its main purpose is heat dissipation. A typical cooling tower includes a tower body, a ventilation system, packing material, and a water distribution system. The water distribution system consists of pipes and a water distributor. The water distributor and water spray nozzles are common water distribution components. The water spray nozzles or water distributors are devices that evenly distribute hot water onto the packing material inside the cooling tower. Water is sprayed through the nozzles, forming fine water droplets to increase the contact area between water and air, thereby improving the cooling efficiency of the cooling tower.

[0003] Currently available nozzles include directional nozzles, rotary nozzles, spray nozzles, and backwash nozzles. Each of these nozzles has its own advantages and disadvantages in its application scenarios, and they can all achieve the effect of uniform water distribution. However, during their use, the amount of water passing through the nozzle is mostly fixed. When the water level in the water distribution basin changes, the amount of water passing through the nozzle remains constant. When the cooling tower's water volume surges and the water level in the water distribution basin becomes too high, conventional nozzles cannot adjust the flow rate in time, leading to overflow, waste, or pollution.

[0004] Therefore, it is necessary to provide a variable flow nozzle for cooling towers to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a variable flow nozzle for cooling towers, which solves the problem that conventional nozzles cannot change the flow rate in a timely manner, leading to overflow, waste, or pollution.

[0006] To solve the above-mentioned technical problems, this utility model provides a variable flow nozzle for cooling towers, comprising:

[0007] A base, the surface of which is fixedly connected with multiple snap-fit ​​pieces;

[0008] A nozzle is disposed inside the base, and the nozzle has multiple flow guide grooves inside, with a petal at one end of the nozzle;

[0009] An adjusting cylinder is disposed inside the nozzle. The adjusting cylinder has multiple triangular holes inside and multiple trapezoidal holes inside.

[0010] Preferably, the base has an internal thread, and the nozzle has an external thread that matches the internal thread.

[0011] Preferably, the petal has a countersunk hole inside, and a self-tapping screw is installed inside the countersunk hole.

[0012] Preferably, a positioning ring is fixedly connected to the bottom of the petal, and the positioning ring has multiple limiting grooves inside.

[0013] Preferably, each of the plurality of limiting grooves is slidably connected to a limiting sleeve, which is made of rubber.

[0014] Preferably, each of the plurality of limiting sleeves has a fixing groove inside, and a fixing block is fixedly connected inside each of the plurality of fixing grooves.

[0015] Preferably, a positioning sleeve is fixedly connected to one end of the fixing block, and a bolt is provided inside the positioning sleeve.

[0016] Compared with related technologies, the variable flow nozzle for cooling towers provided by this utility model has the following beneficial effects:

[0017] This utility model provides a variable flow nozzle for cooling towers. Through triangular and trapezoidal holes, the water level inside the water distribution basin rises to the point where it flows into the nozzle through the triangular hole. After the converging of the conical section and the tightening of the straight pipe section, the water flow is guided through the guide groove on the mounting head to the reverse slope of the petals. Under the push of the reaction force, the petals rotate, and the water is evenly sprayed out. As the water level rises or falls, the inlet surface increases or decreases accordingly, allowing the water level to enter the interior of the trapezoidal hole or decrease to the interior of the triangular hole, thus achieving variable flow. Furthermore, the area of ​​the trapezoidal hole is five to six times the area of ​​the triangular hole, thereby increasing the amount of water sprayed and preventing overflow, waste, or pollution.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First Embodiment

[0026] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a variable flow nozzle for a cooling tower provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the base. Figure 3 for Figure 1 A cross-sectional structural schematic diagram of the base is shown. A variable flow nozzle for a cooling tower includes:

[0027] Base 1, the surface of which is fixedly connected with a plurality of snap-fit ​​pieces 8;

[0028] Nozzle 2, the nozzle 2 is disposed inside the base 1, the nozzle 2 has multiple flow guide grooves 4 inside, and one end of the nozzle 2 is provided with petals 5;

[0029] The regulating cylinder 3 is disposed inside the nozzle 2. The regulating cylinder 3 has multiple triangular holes 31 inside and multiple trapezoidal holes 32 inside.

[0030] The base 1 has an internal thread inside, and the nozzle 2 has an external thread on its surface that matches the internal thread.

[0031] The interior of the petal 5 has a countersunk hole, and a self-tapping screw 7 is installed inside the countersunk hole.

[0032] The regulating cylinder 3 is installed inside the nozzle 2. The regulating cylinder 3 has a conical barrel structure with two pairs of symmetrical through holes, trapezoidal holes 32 and triangular holes 31. The base 1 is installed in the mounting hole at the bottom of the water distribution basin. The inner side of the base 1 has threads, and the outer surface has centrally symmetrical locking pieces 8 for locking the water distribution basin.

[0033] The top of the nozzle 2 has an external thread that mates with the internal thread of the base. The bottom of the nozzle 2 is connected to an installation head via a reinforcing rib. The outer circle of the installation head has a guide groove 4. The nozzle 2 includes a conical section and a straight pipe section. The installation head has a countersunk hole that mates with a self-tapping screw 7 for connecting the petals 5.

[0034] Petal 5 has six petals, and each petal has a reverse bevel, which is arranged clockwise.

[0035] In addition, the external thread of the nozzle 2 and the internal thread of the base 1 can be adjusted up and down within a certain range, which means that the height of the adjusting cylinder can be adjusted within a certain range. This adjustment inside the cooling tower allows the distance between the bottom of the nozzle and the top of the filler to be adjusted within a certain range. As the height of the nozzle is adjusted, the droplets of water sprayed by the petals 5 become more uniform, which can improve the cooling effect of the cooling tower.

[0036] The working principle of the variable flow nozzle for cooling towers provided by this utility model is as follows:

[0037] In use, first install the nozzle 2 on the base 1 via a threaded connection, then insert the adjusting cylinder 3 directly into the inside of the nozzle 2, and install the petals 5 in the countersunk hole of the mounting head of the nozzle 2 via self-tapping screws 7.

[0038] Then, the assembled variable flow nozzle is installed in the mounting hole of the water distribution basin and secured by the snap-fit ​​piece 8.

[0039] In actual operation, hot water enters the water distribution basin through the pipe. When the water level rises to the point where the triangular hole 31 flows into the nozzle, the water flows through the conical section and the straight pipe section, so that the water flows through the guide groove 4 on the mounting head of the nozzle 2 and is guided to the reverse slope of the petal 5. Under the push of the reaction force, the petal 5 rotates and the water is evenly sprayed out.

[0040] The triangular holes 31 and 32 are inverted and set inside the regulating cylinder 3, so that the inlet surface increases or decreases with the rise or fall of the water level to achieve variable flow. The area of ​​the trapezoidal hole 32 is five to six times the area of ​​the triangular hole 31.

[0041] Compared with related technologies, the variable flow nozzle for cooling towers provided by this utility model has the following beneficial effects:

[0042] This utility model provides a variable flow nozzle for cooling towers. Through the triangular hole 31 and trapezoidal hole 32, the water level inside the water distribution basin is raised to the point where it flows into the nozzle 2 through the triangular hole 31. After the converging of the conical section and the tightening of the straight pipe section, the water flow is guided through the guide groove 4 on the mounting head to the reverse inclined surface of the petal 5. Under the push of the reaction force, the petal 5 rotates, and the water is evenly sprayed out. As the water level rises or falls, the inlet surface increases or decreases accordingly, so that the water level enters the interior of the trapezoidal hole 32 or decreases to the interior of the triangular hole 31, thereby achieving variable flow. The area of ​​the trapezoidal hole 32 is five to six times the area of ​​the triangular hole 31, thereby increasing the amount of water sprayed and preventing overflow, waste, or pollution.

[0043] Second Embodiment

[0044] Please refer to the following: Figure 4 and Figure 5 Based on the first embodiment of this application, which provides a variable flow nozzle for a cooling tower, the second embodiment of this application proposes another variable flow nozzle for a cooling tower. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0045] Specifically, the difference in the second embodiment of this application regarding a variable flow nozzle for a cooling tower is that, in a variable flow nozzle for a cooling tower, a positioning ring 9 is fixedly connected to the bottom of the petal 5, and the positioning ring 9 has multiple limiting grooves 10 inside.

[0046] Each of the multiple limiting grooves 10 is slidably connected to a limiting sleeve 11, which is made of rubber.

[0047] The limiting sleeve 11 is used to limit the fixing block 13 by the elasticity of the rubber after the limiting sleeve 11 is inserted into the limiting groove 10, thereby limiting the positioning sleeve 14 and the positioning ring 9.

[0048] Each of the multiple limiting sleeves 11 has a fixing groove 12 inside, and a fixing block 13 is fixedly connected inside each of the multiple fixing grooves 12.

[0049] One end of the fixing block 13 is fixedly connected to a positioning sleeve 14, and a bolt 6 is provided inside the positioning sleeve 14.

[0050] The positioning sleeve 14 has a polygonal groove inside that matches the bolt 6. The positioning sleeve 14 slides on the surface of the bolt 6. After the positioning sleeve 14 drives multiple fixing blocks 13 connected to multiple limiting sleeves 11 to enter the interior of multiple limiting grooves 11, the bolt 6 is limited, thereby preventing the bolt 6 from rotating to one side.

[0051] The working principle of the variable flow nozzle for cooling towers provided by this utility model is as follows:

[0052] In use, the positioning sleeve 14 is placed on the surface of the bolt 6 and then moved to one side, thereby driving multiple fixing blocks 13 connected to multiple limiting sleeves 11 to enter the interior of multiple limiting grooves 10 respectively, and after moving to the appropriate position, the positioning sleeve 14 and the positioning ring 9 are limited.

[0053] When the positioning sleeve 14 is disassembled, by moving the positioning sleeve 14 to one side, multiple fixing blocks 13 connected to multiple limiting sleeves 11 are moved to one side and separated in the multiple limiting grooves 10. After the positioning sleeve 14 is moved to one side and separated on the surface of the bolt 6, the bolt 6 can be rotated to one side and disassembled.

[0054] Compared with related technologies, the variable flow nozzle for cooling towers provided by this utility model has the following beneficial effects:

[0055] This utility model provides a variable flow nozzle for cooling towers. After the positioning sleeve 14 is placed on the surface of the bolt 6 and moved to a suitable position, the fixing block 13 drives the limiting sleeve 11 into the interior of the limiting groove 10, thereby limiting the positioning sleeve 14 and preventing the bolt from rotating and loosening.

[0056] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
