Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, and more specifically, it relates to a modular wet curtain with a high-efficiency spraying structure. Background Technology

[0002] Evaporative cooling pads, as a core component of evaporative cooling systems, are widely used in greenhouses, livestock farming, and industrial ventilation, achieving air cooling and humidification through water evaporation. Traditional evaporative cooling pad structures often use a fixed connection between the integral frame and the pad substrate, requiring complete disassembly for installation or maintenance. This is not only inefficient and cumbersome but also prone to damaging or deforming the pad substrate during disassembly. Furthermore, traditional top-spray systems often use simple unidirectional water distribution pipes (such as a single straight pipe). This design makes it difficult to ensure uniform water distribution across the width of the top of the evaporative cooling pad, easily leading to localized "dry zones" (insufficient water, incomplete evaporation) or "waterlogged zones" (excessive water, obstructing airflow) on the pad surface, severely reducing evaporation efficiency and overall cooling effect. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a modular wet curtain with a high-efficiency spraying structure.

[0004] A modular evaporative cooling pad with a high-efficiency spraying structure includes:

[0005] A hollow frame is formed by an upper frame, side frames, and a bottom frame; a wet curtain body is assembled inside the hollow frame; a first T-shaped block and a second T-shaped block are respectively provided on the upper and lower parts of the wet curtain body;

[0006] An installation cavity is provided in the middle of the upper frame. A main pipe is installed through the installation cavity. A Y-shaped branch pipe is connected to the top of the main pipe. The two ends of the Y-shaped branch pipe pass through the frame wall and are connected to nozzles.

[0007] The upper frame is also provided with guide plates on both sides; the upper and lower parts of the upper frame are respectively provided with first T-shaped grooves; the first T-shaped blocks are fitted into the first T-shaped grooves;

[0008] The upper part of the bottom frame is provided with a second T-shaped groove, and the second T-shaped block is fitted into the first T-shaped groove.

[0009] Furthermore, a third T-shaped block and a fourth T-shaped block are respectively provided at the top and bottom of the side frame; the third T-shaped block is fitted into the first T-shaped groove; and the fourth T-shaped block is fitted into the second T-shaped groove.

[0010] Furthermore, the front and back of the side frame are provided with notches, and threaded holes are provided in the notches; the inner side of the side frame is also provided with a mounting groove, and the wet curtain body is inserted into the mounting groove.

[0011] Furthermore, L-shaped plates are integrally provided on both sides of the bottom edge of the bottom frame, and a drainage channel is formed between the L-shaped plates and the side wall of the bottom frame.

[0012] Furthermore, a third T-shaped groove is provided at the upper part of the upper frame; and a fourth T-shaped groove is provided at the bottom of the lower frame.

[0013] Furthermore, the upper frame is provided with slanted slots on both sides; the guide plate includes an integrally formed plug and a guide, the plug being inserted into the slanted slot.

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

[0015] (1) By installing a main pipe through the cavity in the middle of the upper frame and connecting it with a Y-shaped branch pipe and nozzle, combined with the setting of the guide plate, the main body of the wet curtain is sprayed efficiently and evenly. This fundamentally solves the problem of uneven water distribution caused by traditional unidirectional water distribution pipes, effectively eliminates "dry areas" and "water accumulation areas", ensures that water is distributed evenly and evaporated to the maximum extent on the surface of the wet curtain, and significantly improves the evaporative cooling efficiency and the system cooling capacity.

[0016] (2) By forming a hollow frame consisting of an upper frame, side frames and a bottom frame, and by using the first T-shaped block and the second T-shaped block set on the upper and lower parts of the wet curtain body respectively, which are directly fitted and connected with the first T-shaped groove of the upper frame and the second T-shaped groove of the bottom frame, the wet curtain body and the frame are quickly and accurately positioned and disassembled without tools. This simplifies the process of installing and replacing the wet curtain body, greatly improves the construction and maintenance efficiency, and effectively avoids damage to the wet curtain substrate during the disassembly and assembly process, thereby improving the reliability and service life of the system.

[0027] Example:

[0028] like Figures 1-5 As shown, a modular wet curtain with a high-efficiency spraying structure includes: a hollow frame formed by an upper frame 2, a side frame 3 and a bottom frame 4;

[0029] In this design, a third T-shaped block 31 is provided at the top of the side frame 3, and a fourth T-shaped block 32 is provided at the bottom. First T-shaped grooves 22 are formed on both sides of the lower surface of the upper frame 2 along the length direction. Second T-shaped grooves 41 are formed on both sides of the upper surface of the bottom frame 4 along the length direction. During assembly, the third T-shaped block 31 at the top of the side frame 3 is fitted into the corresponding first T-shaped groove 22 of the upper frame 2 from top to bottom; simultaneously, the fourth T-shaped block 32 at the bottom of the side frame 3 is fitted into the corresponding second T-shaped groove 41 of the bottom frame 4. Through the precise fit of the T-shaped blocks and T-shaped grooves, a quick and stable connection between the side frame and the upper and lower frames is achieved, ensuring the rigidity and sealing of the overall frame without the need for additional fasteners.

[0030] The upper and lower edges of the evaporative cooling pad body 1 are respectively fixed with a first T-shaped block 11 and a second T-shaped block 12. A first T-shaped groove 22 for accommodating the first T-shaped block 11 is formed along the length of the lower surface of the upper frame 2. A second T-shaped groove 41 for accommodating the second T-shaped block 12 is formed along the length of the upper surface of the bottom frame 4. When installing the evaporative cooling pad body 1, the upper first T-shaped block 11 is slid horizontally into the first T-shaped groove 22 of the upper frame 2, while the lower second T-shaped block 12 is simultaneously slid horizontally into the second T-shaped groove 41 of the bottom frame 4. This design achieves precise positioning of the evaporative cooling pad body within the frame and allows for tool-free quick assembly and disassembly.

[0031] Furthermore, the inner side of the side frame 3 is provided with a mounting groove 35 along its height direction. When the T-shaped block of the wet curtain body 1 slides into the T-shaped groove of the upper and lower frame, the two sides of the wet curtain body 1 are precisely inserted into the mounting groove 35 of the side frame 3, further restricting its left and right movement and enhancing overall stability.

[0032] The front and rear surfaces of the side frame 3 have notches 33 at the center or appropriate positions, and threaded holes 34 are machined within the notches 33. After assembly, mounting pieces can be placed in the notches of the side frames of adjacent modules and fixed by screwing bolts into the threaded holes 34, thus achieving the final fastening of the entire evaporative cooling pad module on the mounting frame. The front and rear surfaces typically refer to the surfaces facing adjacent modules or the mounting frame.

[0033] To achieve uniform water spraying, an installation cavity 201 is designed in the middle of the upper frame 2. The main pipe 51 is installed through this installation cavity 201 along the length of the wet curtain. The water inlet of the main pipe 51 is connected to an external water supply system. At the top of the main pipe 51, Y-shaped branch pipes 52 are welded or threaded at certain intervals. The two branch outlets of the Y-shaped branch pipes 52 extend obliquely from the reserved holes in the frame wall of the upper frame 2, pointing towards the top surface of the guide plate wet curtain body 1. At the same time, nozzles 53 are connected and installed at the two branch outlets of each Y-shaped branch pipe 52. The nozzles 53 are preferably fan-shaped or conical nozzles with adjustable spray angles to ensure that the water flow covers the specified width.

[0034] In this design, the upper frame 2 has angled slots 23 on both sides; the guide plate 6 includes an integrally formed insertion part 62 and a guide part 61, with the insertion part 62 inserted into the angled slots 23. Specifically, the guide part 61 is located on both sides below the water outlet of the nozzle 53. The function of the guide plate 6 is to guide the water flow from the nozzle to the surface of the wet curtain body 1, preventing water from splashing to both sides or directly impacting the side frame, ensuring that the water flow is concentrated and evenly wets the top of the wet curtain.

[0035] To reduce water accumulation and prevent damage to the evaporative cooling pad, L-shaped plates 43 extend integrally downwards and outwards from the bottom of both sides of the bottom frame 4. The L-shaped plates 43 and the side walls of the bottom frame 4 together form a downward-opening drainage channel 44. During use, water that is not completely absorbed or evaporated by the evaporative cooling pad 1 flows down the surface of the cooling pad to the bottom under gravity. The upper surface of the bottom frame 4 is designed with a slight slope to guide the water flow. The collected water eventually flows into the drainage channel 44 formed by the L-shaped plates 43 on both sides. The drainage channel 44 smoothly discharges wastewater to the outside of the evaporative cooling pad module, connecting to a water collection tank or recycling pipe, effectively preventing water accumulation at the bottom.

[0036] Meanwhile, to enable rapid assembly and disassembly of multiple modular evaporative cooling pads, a third T-slot 21 is formed in the middle of the upper surface of the upper frame 2, parallel to the first T-slot 22. A fourth T-slot 42 is formed in the middle of the lower surface of the bottom frame 4. The third T-slot 21 and the fourth T-slot 42 can be interlocked with I-beam blocks when installed with other evaporative cooling pad modules, enabling rapid stacking of multiple evaporative cooling pad modules. Vertical or side-by-side splicing requires the use of connectors to meet the application requirements of different sizes and air volumes.

[0037] The working process of this modular evaporative cooling pad is as follows: An external water pump starts, delivering cooling water through pipes to the main pipe 51. After entering the main pipe 51, the water flow is distributed to various Y-shaped branch pipes 52. Each Y-shaped branch pipe 52 evenly divides the water flow into two, which then flow to their left and right branches respectively. The water is sprayed out from nozzles 53 at the ends of the branches, forming a uniform water curtain or water line.

[0038] The sprayed water jets impact the guide plate 6, which constrains and guides the water flow, ensuring it precisely covers the central area or surface of the evaporative cooling pad 1. Under the influence of gravity, capillary action, and airflow, the water sprayed onto the top of the evaporative cooling pad penetrates downwards evenly, soaking the entire honeycomb or corrugated structure of the evaporative cooling pad 1. When hot air requiring cooling is driven laterally by a fan through the fully soaked evaporative cooling pad 1, the water absorbs heat from the air and evaporates, significantly reducing the air temperature and increasing the humidity, thus achieving evaporative cooling.

[0039] Some of the water that is not evaporated or not completely absorbed by the wet curtain, i.e., wastewater, flows to the bottom of the wet curtain. The wastewater collects on the upper surface of the bottom frame 4. Guided by the slope of the bottom frame 4 and the drainage channel 44 formed by the L-shaped plate 43, the wastewater is effectively collected and smoothly discharged from the module into the external water collection system, avoiding water accumulation.

[0040] Modular operation: Loosen the side frame fixing bolts and slide the old wet curtain body 1 horizontally out along the T-slot; align the first T-block 11 and the second T-block 12 of the new wet curtain body 1 with the first T-slot 22 of the upper frame 2 and the second T-slot 41 of the bottom frame 4 respectively, and insert the mounting slots 35 of the side frame 3 on both sides.

[0041] Extended connection: By embedding the T-shaped blocks or dedicated connectors of the side borders of adjacent modules into the third T-shaped slot 21 of the upper border and / or the fourth T-shaped slot 42 of the bottom border of this module, the modules can be quickly spliced ​​or stacked.

Many modifications and variations will be apparent to those skilled in the art.
