Description

Technical Field

[0001] This utility model belongs to the field of cooling tower technology, and more specifically, it relates to a cooling tower with high-efficiency sewage discharge. 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 mechanism utilizes the heat exchange between water and air to generate steam. The steam evaporates and carries away heat, achieving heat dissipation through evaporation, convection, and radiation. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems, thereby lowering the water temperature and ensuring the normal operation of the system. Hence, it is called a cooling tower.

[0003] Based on the above, the following problems were found: When using existing cooling towers, cleaning the cooling packing is of paramount importance. The cooling packing directly affects the water flow rate of the cooling tower, thus affecting the cooling efficiency. Due to long-term water erosion, the outer wall of the cooling packing is prone to a large amount of scale. Existing cleaning devices usually only clean the top of the cooling packing, while the cooling packing is usually mesh-like and has a large amount of scale inside.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a cooling tower with high-efficiency sewage discharge, so as to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cooling tower with high-efficiency sewage discharge, which solves the problem that current cleaning devices usually only clean the top of the cooling packing, while the cooling packing is usually mesh-like and has a lot of scale inside.

[0006] This utility model provides a cooling tower with high-efficiency sewage discharge, achieved through the following specific technical means:

[0007] A high-efficiency sewage discharge cooling tower includes a cooling tower body, with a drain pipe fixed through the bottom of one end of the cooling tower body. A grating plate is provided in the middle of one side of the cooling tower body. Cooling filler is fixed in the lower middle of the inner wall of the cooling tower body. A hanger rod is fixed in the top of the inner wall of the cooling tower body. First guide rails are fixed at the bottom of both ends of the hanger rod. A second guide rail and a first servo motor are movably installed in the middle of the two first guide rails. An electric telescopic rod is fixed in the bottom of the hanger rod. The power output end of the electric telescopic rod is fixed in the middle of the second guide rail. A lateral moving mechanism is provided in the bottom of the second guide rail. A gear box is fixed in the bottom of the lateral moving mechanism. A first gear is rotatably connected to the inner wall of the gear box. A second servo motor is fixed in the top of the outer wall of the gear box. A driven rod is fixed in the bottom of the first gear. A cleaning rod is fixed in the outer wall of the driven rod. A light distance sensor is fixed in one side of the gear box.

[0008] Furthermore, each of the two first guide rails has a sliding groove on its opposite side, one end of the second guide rail is fixed to the outer wall of the first servo motor, and the opposite ends of the second guide rail and the first servo motor are each fixed with a first slider, and the two first sliders are slidably connected to the two sliding grooves.

[0009] Furthermore, multiple first gears are provided, and the number of mesh holes in the same column of the multiple first gears corresponds to the number of mesh holes in the cooling filler. The power output end of the second servo motor is fixed to one of the first gears, and the multiple first gears mesh with each other in pairs.

[0010] Furthermore, the optical distance sensor is used to detect the distance between the gearbox and the cooling packing, and also to control the extension and retraction of the electric telescopic rod.

[0011] Furthermore, the lateral movement mechanism includes a second slider, which is slidably connected to a second guide rail. A threaded rod is fixed to the power output end of the first servo motor, and the threaded rod is threadedly connected to the second slider. The bottom of the second slider is fixed to the second servo motor.

[0012] Furthermore, the length of the driven rod is greater than the height of the cooling packing. Multiple sets of cleaning rods are provided, and the multiple sets of cleaning rods are arranged vertically at equal intervals. Each set of cleaning rods has multiple cleaning rods, and the multiple cleaning rods are arranged in a circumferentially at equal intervals. The length of the cleaning rod is greater than the distance between the driven rod and the inner wall of the cooling packing.

[0013] Furthermore, the top of the gearbox is sealed, a waterproof cover is fixed to the outer wall of the second servo motor, and the vertical interface of the second guide rail is in an inverted U-shape.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the rotation of the first servo motor drives the optical distance sensor to change its position. When the optical distance sensor detects an increase in distance, the driven rod is positioned directly above the hole of the cooling packing. Subsequently, the electric telescopic rod extends and inserts the driven rod into the hole of the cooling packing. The second servo motor starts to clean, and the driven rod drives the cleaning rod to rotate in the hole of the cooling packing. After the driven rod cleans for a certain period of time, the second servo motor stops, the electric telescopic rod shortens, and the first servo motor continues to rotate, thoroughly cleaning the entire cooling packing, thereby achieving the effect of thoroughly cleaning the internal holes of the cooling packing.

[0016] 2. In this utility model, the length of the driven rod is greater than the height of the cooling packing. After the driven rod is inserted into the cooling packing, both the top and bottom ends of the driven rod are located outside the holes of the cooling packing. The cleaning rod can touch the top and bottom of the cooling packing, which can thoroughly clean the cooling packing. This achieves the effect of cleaning the inside while effectively cleaning the top and bottom of the cooling packing. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a high-efficiency sewage discharge cooling tower, including a cooling tower body 1, a drain pipe 2 fixed through the bottom of one end of the cooling tower body 1, a grid plate 17 set in the middle of one side of the cooling tower body 1, a cooling filler 3 fixed in the lower middle of the inner wall of the cooling tower body 1, a hanging rod 4 fixed in the top of the inner wall of the cooling tower body 1, a first guide rail 5 fixed in the bottom of both ends of the hanging rod 4, a second guide rail 6 and a first servo motor 7 movably installed in the middle of the two first guide rails 5, an electric telescopic rod 8 fixed in the bottom of the hanging rod 4, the power output end of the electric telescopic rod 8 fixed in the middle of the second guide rail 6, a lateral moving mechanism set in the bottom of the second guide rail 6, a gear box 12 fixed in the bottom of the lateral moving mechanism, a first gear 13 rotatably connected in the inner wall of the gear box 12, a second servo motor 11 fixed in the top of the outer wall of the gear box 12, a driven rod 14 fixed in the bottom of the first gear 13, a cleaning rod 15 fixed in the outer wall of the driven rod 14, and a light distance sensor 16 fixed in one side of the gear box 12.

[0028] The two first guide rails 5 are provided with sliding grooves 51 on opposite sides. One end of the second guide rail 6 is fixed to the outer wall of the first servo motor 7. The opposite ends of the second guide rail 6 and the first servo motor 7 are both fixed with first sliders 71. The two first sliders 71 are slidably connected to the two sliding grooves 51. The electric telescopic rod 8 extends and retracts, driving the second guide rail 6 and the first servo motor 7 to move up and down, thereby controlling the position of the driven rod 14 and the cleaning rod 15.

[0029] The first gear 13 is provided in multiple ways, and the number of mesh holes in the same column of the cooling filler 3 corresponds to the number of the first gear 13. The power output end of the second servo motor 11 is fixed to one of the first gears 13, and the multiple first gears 13 mesh with each other in pairs. The second servo motor 11 drives one of the first gears 13 to rotate, which in turn drives multiple first gears 13 to rotate together. The driven rod 14 drives the cleaning rod 15 to rotate in the holes of the cooling filler 3 to clean the scale.

[0030] The optical distance sensor 16 is used to detect the distance between the gear box 12 and the cooling filler 3, and also to control the extension and retraction of the electric telescopic rod 8. First, the first servo motor 7 rotates, driving the threaded rod 72 to rotate, which in turn drives the first slider 9 to slide, causing the position of the optical distance sensor 16 to change. When the optical distance sensor 16 detects an increase in distance, it indicates that one side of the gear box 12 is located at the edge of the cooling filler 3, and the driven rod 14 is located directly above the hole in the cooling filler 3. Then, the optical distance sensor 16 sends a signal to extend the electric telescopic rod 8 and insert the driven rod 14 into the hole in the cooling filler 3. Subsequently, the second servo motor 11 starts to clean. After cleaning for 10-20 seconds, the second servo motor 11 stops, the electric telescopic rod 8 shortens, and the first servo motor 7 continues to rotate.

[0031] The lateral movement mechanism includes a second slider 9, which is slidably connected to the second guide rail 6. A threaded rod 72 is fixed to the power output end of the first servo motor 7. The threaded rod 72 is threadedly connected to the second slider 9. The bottom of the second slider 9 is fixed to the second servo motor 11. The rotation of the first servo motor 7 drives the threaded rod 72 to rotate, thereby driving the slider 9 to slide inside the second guide rail 6 to adjust the position of the second servo motor 11.

[0032] The length of the driven rod 14 is greater than the height of the cooling packing 3. Multiple sets of cleaning rods 15 are arranged vertically at equal intervals. Each set of cleaning rods 15 has multiple rods, which are arranged in a circular, equidistant pattern. The length of the cleaning rod 15 is greater than the distance between the driven rod 14 and the inner wall of the cooling packing 3. This ensures that after the driven rod 14 is inserted into the cooling packing 3, both the top and bottom ends of the driven rod 14 are located outside the holes of the cooling packing 3. The cleaning rod 15 can touch the top and bottom of the cooling packing 3, thus cleaning the cooling packing 3 thoroughly.

[0033] The gear box 12 is sealed at the top, the second servo motor 11 is fixed with a waterproof cover 10 on its outer wall, and the vertical interface of the second guide rail 6 is inverted U-shaped. The waterproof cover 10 protects the second servo motor 11, the gear box 12 protects the multiple first gears 13 inside, and the inverted U-shaped second guide rail 6 protects the threaded rod 72 inside, preventing it from being corroded and rusted by water, thus affecting its subsequent normal operation.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, the first servo motor 7 rotates, driving the threaded rod 72 to rotate, which in turn drives the first slider 9 to slide, causing the position of the optical distance sensor 16 to change. When the optical distance sensor 16 detects an increase in distance, it indicates that one side of the gear box 12 is located at the edge of the cooling packing 3, and the driven rod 14 is located directly above the hole in the cooling packing 3. Subsequently, the optical distance sensor 16 sends a signal, causing the electric telescopic rod 8 to extend and insert the driven rod 14 into the hole in the cooling packing 3. Then, the second servo motor 11 starts to clean, driving one of the first gears... The wheel 13 rotates, which in turn drives multiple first gears 13 to rotate together. The driven rod 14 drives the cleaning rod 15 to rotate in the hole of the cooling packing 3. After the driven rod 14 is inserted into the cooling packing 3, the top and bottom ends of the driven rod 14 are located outside the hole of the cooling packing 3. The cleaning rod 15 can touch the top and bottom of the cooling packing 3, which can thoroughly clean the cooling packing 3 and remove scale. After cleaning for 10-20 seconds, the second servo motor 11 stops, the electric telescopic rod 8 shortens, and the first servo motor 7 continues to rotate, thoroughly cleaning the entire cooling packing 3.

[0036] Among them, the optical distance sensor 16 is model STK32562, which has the function of optical distance measurement and also has the function of providing control signals, which can control the extension and retraction of the electric telescopic rod 8.
