Description

Technical Field

[0001] This utility model relates to the field of water distributor technology, and in particular to a water distributor that is not easily clogged. Background Technology

[0002] A chilled water storage system is a form of energy-saving air conditioning that utilizes off-peak electricity at night to power a dual-mode electric chiller unit. The cooling capacity is stored as chilled water in a chilled water tank, and then released during the day. The water distributor's function is to smoothly introduce the cooled water from the chiller unit into the chilled water tank, creating a stratified system that minimizes the mixing of hot and cold water. Its design is crucial for ensuring the efficient operation of the chilled water storage system.

[0003] Over time, impurities accumulate in chilled water tanks. When no water is being supplied to the distributor, these impurities can enter the distributor's pipes, easily causing blockages. Furthermore, some distributors use slotted or micro-perforated outlet methods, making them highly susceptible to blockage by rust and welding slag in the chilled water storage pipes. Blockage in the distributor affects the uniformity of water flow distribution, increases the length of the thermocline, exacerbates cold loss, and reduces the chilled water storage capacity efficiency of the storage tank. Utility Model Content

[0004] This invention provides a water distributor that is less prone to clogging, in order to solve the above-mentioned technical problems.

[0005] This utility model provides a water distributor that is not easily clogged, including a main water distribution cylinder and four connecting branch pipes. The four connecting branch pipes are circumferentially connected to the side wall of the main water distribution cylinder. Each connecting branch pipe is provided with a water distribution branch pipe. The main water distribution cylinder is provided with a preliminary filtration structure, which is detachably connected to the main water distribution cylinder. Each water distribution branch pipe is provided with an impurity scraping structure, which slides with the water distribution branch pipe. Each water distribution branch pipe is provided with several equally spaced water outlet holes. The bottom of the main water distribution cylinder is provided with a water distribution support structure. The main water distribution cylinder is provided with a detachable water inlet pipe.

[0006] Furthermore, the preliminary filtration structure includes a filter screen, a mounting frame, and four mounting blocks. The four mounting blocks are distributed circumferentially on the side wall of the mounting frame. The main water distribution cylinder is provided with four mounting slots, and the four mounting blocks are respectively installed in the four mounting slots. The mounting blocks are provided with connecting bolts for connecting with the main water distribution cylinder. The filter screen is horizontally connected to the mounting frame.

[0007] Furthermore, each of the connecting branch pipes is provided with a first flange at one end, and each of the water distribution branch pipes is provided with a second flange at one end that is connected to the first flange.

[0008] Furthermore, each of the water distribution branch pipes has a connector at the other end, and a rubber plug is provided inside the connector.

[0009] Furthermore, each of the impurity scraping structures includes a circular scraping ring, two tension springs, and four scraping plates. A connecting disc is provided in the middle of the circular scraping ring, and the four scraping plates are evenly distributed on the circular scraping ring. Four elongated grooves are provided in the water distribution branch pipe at the water outlet. The scraping plates are slidably engaged with the elongated grooves. One end of each of the two tension springs is connected to the side wall of the disc, and the other end of each of the two tension springs is connected to the inner side wall of the water distribution branch pipe.

[0010] Furthermore, the water distribution support structure includes a support plate, a support rod, and a plug rod. The support rod is vertically installed on the top of the support plate, and the plug rod is vertically connected to the bottom of the main water distribution cylinder. The support rod slides on the plug rod, and the plug rod is provided with a plurality of equally spaced plug screw holes. The support rod is provided with a plug screw that is threadedly connected to the plug screw holes.

[0011] Furthermore, the support plate is provided with four mounting holes.

[0012] This utility model provides an improved water distributor that is less prone to clogging, which has the following improvements and advantages compared with the prior art:

[0013] Firstly, the filter screen of this utility model serves as the first line of defense, accurately intercepting suspended particles, silt, algae, rust, and other impurities in the water, preventing them from entering the main water distribution cylinder and branch pipes. If these impurities directly enter the branch pipes, they are very likely to get stuck at the outlet, causing blockages. The filter screen, however, acts as a front-line interceptor, cutting off the cause of blockages at the source. After a period of use, the connecting bolts can be disassembled one by one, allowing the mounting frame to be removed from the main water distribution cylinder for cleaning the impurities filtered out by the filter screen. The detachable design facilitates regular disassembly and cleaning of the trapped impurities, ensuring the filter screen continues to work efficiently and maintains a stable filtration effect over a long period. It also reduces the scouring and wear of impurities on the branch pipes and outlet, minimizing damage to the equipment caused by blockages, extending the service life of the water distributor and the entire water storage cooling system, reducing equipment maintenance and replacement costs, and improving the economy and reliability of the system operation.

[0014] Secondly, during backwashing, this invention delivers high-pressure water into the distribution branch pipe via the backwash pipe. This high-pressure water provides a dual cleaning effect: first, the powerful water flow directly washes the inner wall of the distribution branch pipe, quickly peeling off and removing attached impurities; second, when the high-pressure water impacts the disc and circular scraper ring, it drives the circular scraper ring to move four scraper plates along the inner wall and long groove of the distribution branch pipe. During this process, the circular scraper ring and scraper plates form a three-dimensional cleaning surface, which not only removes stubborn deposits from the inner wall of the branch pipe but also specifically cleans impurities at the outlet pipe. As the disc moves under the pressure of the water flow, the tension spring simultaneously deforms and stores elastic potential energy. After backwashing, the spring returns to its original position using its own elasticity, precisely returning the disc and circular scraper ring to their initial positions, ensuring unobstructed flow within the distribution branch pipe and preventing water flow uniformity from being affected by mechanical stagnation, thus guaranteeing the stability and efficiency of subsequent water distribution operations.

Detailed Implementation

[0023] The following will be combined with the appendix Figures 1 to 6This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] This utility model provides an improved water distributor that is less prone to clogging, comprising a main water distribution cylinder 1 and four connecting branch pipes 10. The four connecting branch pipes 10 are circumferentially connected to the side wall of the main water distribution cylinder 1. Each connecting branch pipe 10 is provided with a water distribution branch pipe 11. The main water distribution cylinder 1 is provided with a preliminary filtration structure 2, which is detachably connected to the main water distribution cylinder 1. Each water distribution branch pipe 11 is provided with an impurity scraping structure 3, which is slidably engaged with the water distribution branch pipe 11. Each water distribution branch pipe 11 is provided with a plurality of equally spaced water outlet holes 12. The bottom of the main water distribution cylinder 1 is provided with a water distribution support structure 4. The main water distribution cylinder 1 is provided with a detachable water inlet pipe 5.

[0025] The water inlet pipe 5 delivers water to the inside of the main water distribution cylinder 1.

[0026] Specifically, the preliminary filtration structure 2 includes a filter screen 21, a mounting frame 22, and four mounting blocks 23. The four mounting blocks 23 are distributed circumferentially on the side wall of the mounting frame 22. The main water distribution cylinder 1 is provided with four mounting grooves 13. The four mounting blocks 23 are respectively installed in the four mounting grooves 13. The mounting blocks 23 are provided with connecting bolts 24 for connecting with the main water distribution cylinder 1. The filter screen 21 is horizontally connected to the mounting frame 22.

[0027] As the first line of defense, the filter screen 21 can accurately intercept suspended particles, silt, algae, rust, and other impurities in the water, preventing them from entering the main water distribution cylinder 1 and the branch water distribution pipes 11. If these impurities directly enter the branch water distribution pipes 11, they are very likely to get stuck at the outlet holes 12, causing blockages. The filter screen 21 acts as a front-line interceptor, cutting off the cause of blockages at the source. After a period of use, the inlet pipe 5 is first removed from the main water distribution cylinder 1, and then the connecting bolts 24 are removed in sequence. The mounting frame 22 can then be removed from the main water distribution cylinder 1 to clean the impurities filtered by the filter screen 21. The detachable design facilitates regular disassembly and cleaning of the trapped impurities, ensuring that the filter screen 21 continues to work efficiently and maintains a stable filtration effect over a long period. This reduces the scouring and wear of impurities on the branch water distribution pipes 11 and the outlet holes 12, reduces damage to the equipment caused by blockages, extends the service life of the water distributor and the entire water storage cooling system, reduces equipment maintenance and replacement costs, and improves the economy and reliability of the system operation.

[0028] Specifically, each of the connecting branch pipes 10 is provided with a first flange 14 at one end, and each of the water distribution branch pipes 11 is provided with a second flange 15 connected to the first flange 14 at one end. A rubber gasket is provided between the first flange 14 and the second flange 15 to ensure a seal between them.

[0029] Specifically, each of the water distribution branch pipes 11 has a connector 16 at the other end, and a rubber plug 17 is provided inside the connector 16.

[0030] During the backwashing process of the water distributor, the rubber stopper 17 can be pulled out from the inlet 16, and then the water pipe for backwashing can be connected to the inlet 16 to deliver the backwashing water into the water distributor, thereby realizing the backwashing of the water distributor.

[0031] Specifically, each of the impurity scraping structures 3 includes a circular scraping ring 31, two tension springs 32, and four scraping plates 33. The circular scraping ring 31 has a connected disc 34 in the middle. The four scraping plates 33 are evenly distributed on the circular scraping ring 31. The water distribution branch pipe 11 has four elongated grooves 18 located at the water outlet 12. The scraping plates 33 and the elongated grooves 18 are slidably engaged. One end of the two tension springs 32 is connected to the side wall of the disc 34, and the other end of the two tension springs 32 is connected to the inner side wall of the water distribution branch pipe 11.

[0032] During backwashing, the backwash pipe delivers high-pressure water into the water distribution branch pipe 11. This high-pressure water has a dual cleaning effect: First, the powerful water flow directly washes the inner wall of the water distribution branch pipe 11, quickly peeling off and removing attached impurities. Second, when the high-pressure water impacts the disc 34 and the circular scraping ring 31, it drives the circular scraping ring 31 to move the four scraping plates 33 along the inner wall of the water distribution branch pipe 11 and the elongated groove 18. In this process, the circular scraping ring 31 and the scraping plates 33 form a three-dimensional cleaning surface, which can not only scrape off stubborn deposits on the inner wall of the water distribution branch pipe 11, but also specifically clean impurities at the water outlet 12. When the disc 34 is moved by the water flow, the tension spring 32 deforms simultaneously and stores elastic potential energy. After backwashing, the tension spring 32 returns to its original position by its own elasticity, driving the disc 34 and the circular scraper ring 31 back to their initial positions precisely. This ensures that the internal flow channels of the water distribution branch pipe 11 are unobstructed, avoiding the impact of mechanical parts stagnation on the uniformity of water flow, thereby ensuring the stability and efficiency of subsequent water distribution operations.

[0033] Specifically, the water distribution support structure 4 includes a support plate 41, a support rod 42, and a plug rod 43. The support rod 42 is vertically arranged on the top of the support plate 41, and the plug rod 43 is vertically connected to the bottom of the water distribution main cylinder 1. The support rod 42 slides on the plug rod 43. The plug rod 43 is provided with a plurality of equally spaced plug screw holes 44, and the support rod 42 is provided with a plug screw 45 that is threadedly connected to the plug screw holes 44.

[0034] To prevent clogging of the water distributor outlet 12, an adjustable height structure is incorporated into the installation process. By pulling out the plug-in screw 45, the plug-in rod 43 can slide freely along the support rod 42. Installers can flexibly adjust the vertical position of the water distributor according to the water storage cooling conditions. After adjusting to the ideal height, the plug-in screw 45 is screwed back into the corresponding screw holes of the support rod 42 and the plug-in rod 43 to achieve a secure connection. This design effectively ensures that the four water distribution branch pipes 11 of the water distributor maintain a safe distance from the bottom of the cooling tank, avoiding the risk of clogging of the outlet 12 due to impurity deposition during water distribution, and significantly improving the reliability and stability of the water distributor's operation.

[0035] Specifically, the support plate 41 is provided with four mounting holes 46. The support plate 41 can be installed in the cold storage tank by installing expansion screws in the four mounting holes 46, thereby realizing the installation of the water distributor.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
