Description

Technical Field

[0001] The present invention relates to the technical field of filtering devices, and specifically relates to a water filtering device. Background Art

[0002] The original filtering system in the cooling tower sump of the second circulating water field in the second public works department has poor filtering effect and frequent blockages, resulting in a high front-back liquid level difference between the tower pool and the sump. The designed treatment capacity of the second circulating water field reaches as high as 40,000 m3 / h, and the flow rate of the circulating water is large and the velocity is high. If the filtering system is not thoroughly cleaned, it will cause the front-back liquid level difference between the tower pool and the sump to continuously increase, and the risk of the pump inlet pipeline being evacuated is extremely high, seriously threatening the stable operation of production. There has been a phenomenon of pump evacuation, which has caused fluctuations in the supply of circulating water and has become a bottleneck problem affecting the stable operation of the device. Moreover, the filter screen of the existing filtering system is heavy, and it needs to be cleaned at least once a month on average, and it needs to be cleaned every week in summer, which is difficult to operate and inconvenient to clean. In order to overcome the deficiencies of the prior art and solve the technical bottleneck problems of the existing filtering system in the cooling tower sump of the circulating water field that is frequently blocked and affects the supply of circulating water.

[0003] Currently, the domestic similar industries mainly adopt forms such as manually-operated hoist lifting mechanical grilles and electric hoist suspended grilles, which have difficulties in operation, high equipment failure rates, and poor filtering effects in actual use. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a water filtering device, which solves the problems of difficult operation, high equipment failure rate, and poor filtering effect existing in traditional filtering devices.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A water filtering device includes a willow-shaped rail, a willow-shaped rail shaft is arranged inside the willow-shaped rail, a spring is arranged inside the willow-shaped rail shaft, a locknut is threadedly connected to the outer wall of the willow-shaped rail, a cross brace is arranged above the willow-shaped rail, a vertical frame is arranged on one side of the outer wall of the willow-shaped rail, an inclined plate is arranged at the bottom of the willow-shaped rail, a bottom frame is fixedly connected to the lower surface of the inclined plate, and a filter screen frame is slidably connected inside the vertical frame.

[0006] Preferably, a filter screen is slidably connected inside the filter screen frame, a slideway is arranged on one side of the outer wall of the filter screen, and a pressing plate is arranged on one side of the outer wall of the filter screen.

[0007] Preferably, a handle is fixedly connected to one side of the outer wall of the filter screen frame, a connecting plate is arranged on the outer wall of the filter screen frame, and a reinforcing rib plate is arranged on one side of the outer wall of the connecting plate.

[0008] Preferably, a plurality of welding points are arranged on the upper surface of the connecting plate.

[0009] Preferably, the filter frame is welded with channel steel on all sides and in the middle, and the filter frame is made into a structure capable of placing three layers of six filters inside, so that the overall filtration is more refined.

[0010] Preferably, the frame of the filter screen is made of a lightweight square tube, the stainless steel mesh is riveted and pressed firmly with a stainless steel pressing plate, and is welded point by point with argon arc welding.

[0011] Preferably, the inner corners of the spring are welded with reinforced ribs, which reduces the weight of the filter and improves the overall strength.

[0012] Preferably, the slide is a round steel slide, and a slide is provided on one side of the frame of the filter, which ensures that the filter can be lifted smoothly and that the two layers of the filter are spaced appropriately from front to back.

[0013] Preferably, the willow leaf rail, spring and willow leaf rail shaft are combined into a spring-type willow leaf rail, and the rail is designed as a one-way valve to prevent the filter from sliding out by itself in a non-operating state, so as to enhance operational safety.

[0014] Preferably, the inclined plate is designed to facilitate the filter to automatically slide down when cleaning is required, thereby further improving operational convenience.

[0015] Working principle: This type of industrial circulating water field water collection pool filtration device has more filter layers, finer mesh specifications, and more obvious filtering effect. The single filter is light in weight. It used to require multiple people to lift it with a hand-pulled hoist, but now only one operator can easily pull it out and clean it. A spring-type willow leaf rail is set at the top of the frame, which acts as a "one-way valve", and a slope is set at the bottom. During operation, only the first filter can be taken out, and the second filter will automatically slide to the position of the first filter before the second filter can be taken out. Prevent misoperation and prevent debris from entering the next filter. A movable baffle is set at the end of the entire filtration system to achieve online cleaning of the entire filtration system during the operation of the circulating water device. A round steel slide is set on one side of the frame of the filter, which not only ensures the smooth lifting of the filter but also ensures that the two layers of filter maintain an appropriate distance between the front and back. In actual use, the filtration effect is greatly improved, and the solid impurities contained in the circulating water are effectively intercepted and removed, reducing the blockage of the water pump and heat exchanger in the subsequent process.

[0016] The present invention provides a water filtering device having the following beneficial effects: 1. The present invention improves the filtering effect in actual use through technical transformation, effectively intercepts and removes solid impurities contained in circulating water, and the filter screen is well cleaned, reducing the blockage of water pumps and heat exchangers in the subsequent processes. The liquid level difference before and after the filter screen is eliminated, and the phenomenon of pump suction pipeline being emptied is eliminated, so that the water pump runs stably and the circulating water is supplied stably, providing a strong guarantee for the stable operation of the production device and improving the "safe, stable, long-term, full and excellent" operation of the device.

[0017] 2. The unique design of the water filtration device and the fine filter screen of the present invention can effectively improve the water quality, make the circulating water cleaner, reduce the risk of blockage of other equipment such as water pumps and heat exchangers, and thus improve the operation efficiency and service life of the equipment.

[0018] 3. Through the design of the spring-type willow leaf rail of the present invention, the equipment can be safe and stable in the non-working state, avoiding the safety hazards brought by the self-sliding of the filter screen, improving the work safety of the operators. The slope design of the equipment enables the filter screen to slide down automatically when it needs to be cleaned, which greatly simplifies the cleaning process, reduces the manual labor intensity, and improves the work efficiency.

[0019] 4. The filtration device involved in the invention has multiple layers of filter screens and fine mesh specifications, and the filtration effect is more obvious. The single-piece filter screen is light in weight, and only one operator can easily pull it out for cleaning. The total number of filter screens in the filtration system involved in the invention is a three-layer structure, and the mesh specifications are more refined. It has an anti-misoperation function and an online cleaning function of the whole set of filtration devices during operation. In actual use, it has the characteristics of good filtration effect, convenient operation, simple and firm structure, and good practicability, greatly reducing the occurrence of blockage of water pumps and heat exchangers in the subsequent processes. It improves the continuous stability of the chemical plant production. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Please refer to the attached Figure 1 -attached Figure 2, an embodiment of the present invention provides a water filtration device, including a willow leaf rail 1. Inside the willow leaf rail 1, there is a willow leaf rail shaft 2. Inside the willow leaf rail shaft 2, there is a spring 3. The outer wall of the willow leaf rail 1 is threadedly connected with a locknut 4. Above the willow leaf rail 1, there is a cross brace 5. On one side of the outer wall of the willow leaf rail 1, there is a vertical frame 6. At the bottom of the willow leaf rail 1, there is an inclined plate 8. The lower surface of the inclined plate 8 is fixedly connected with a bottom frame 7. Inside the vertical frame 6, a filter screen frame 303 is slidably connected.

[0024] Inside the willow leaf rail 1 of the device, there is a willow leaf rail shaft 2. Inside the willow leaf rail shaft 2, there is a spring 3. This structure enables the willow leaf rail shaft 2 to undergo elastic deformation under the action of the spring 3, thereby achieving the effects of buffering and vibration absorption. During actual operation, this design can effectively prevent the filter screen from sliding out by itself in the non-working state, enhancing the safety of operation. The outer wall of the willow leaf rail 1 is threadedly connected with a locknut 4. The locknut 4 can fix the willow leaf rail 1 and the willow leaf rail shaft 2, preventing loosening of the connection caused by long-term use and ensuring the stable operation of the device. Above the willow leaf rail 1, there is a cross brace 5. On one side of the outer wall, there is a vertical frame 6. The settings of the cross brace 5 and the vertical frame 6 enhance the overall stability of the device, ensuring the stability of the device during use. At the bottom of the willow leaf rail 1, there is an inclined plate 8. The lower surface of the inclined plate 8 is fixedly connected with a bottom frame 7. The design of the inclined plate 8 allows the filter screen to slide down automatically when it needs to be cleaned, reducing the labor intensity of the operator. The bottom frame 7 can collect and store the slid-down filter screen, facilitating subsequent cleaning and processing.

[0025] In one embodiment, through the willow leaf rail 1 shaft with a spring 33 inside and the locknut 4 threadedly connected to the outer wall, a stable structure and safety measures to prevent the filter screen 707 from sliding out by itself are achieved, thereby enhancing the stability and operation safety of the filter screen 707. By fixedly connecting a handle 202 to one side of the outer wall of the spring 33, and setting the locknut 4 and reinforcing rib plates 505, the operation convenience of the device and the stability of the device are improved. The designs of the cross brace 5 and the vertical frame 6 also improve the overall stability of the device. By welding reinforcing rib plates 505 at the inner corner of the spring 3 and setting an inclined plate 8 at the bottom, it is beneficial for the filter screen 707 to slide down automatically when it needs to be cleaned, further enhancing the operation convenience. The design of this water filtration device makes the filtration more refined, can meet the high requirements for water quality in different industries, increases the application scope of the device. Since the design and manufacturing process of this device fully consider the stability and durability of the device, the device can maintain good performance during long-term use, reducing the need for frequent equipment replacement, thereby reducing the operating cost and improving production efficiency.

[0026] Inside the filter screen frame 303, a filter screen 707 is slidably connected. On one side of the outer wall of the filter screen 707, there is a slideway 808. On one side of the outer wall of the filter screen 707, there is a pressing plate 606.

[0027] During the water filtration process, water flows through the filter screen 707, and most of the impurities are intercepted by the filter screen 707. On one side of the outer wall of the filter screen 707, there is a slideway 808. The design of the slideway 808 enables the filter screen 707 to slide out more smoothly when it needs to be cleaned, reducing the resistance during the cleaning process and improving the cleaning efficiency. On one side of the outer wall of the filter screen 707, there is a pressing plate 606. The pressing plate 606 can fix the filter screen 707 to prevent the filter screen 707 from sliding out by itself in the non-working state, improving the safety of operation.

[0028] In one embodiment, due to the presence of the filter screen 707, the water filtration device can effectively intercept impurities in the water, thereby improving the filtration effect. And on one side of the outer wall of the filter screen 707, there is a slideway 808, enabling the filter screen 707 to slide out more smoothly when it needs to be cleaned, thereby improving the convenience of operation. Since there is a pressing plate 606 on one side of the outer wall of the filter screen 707, it can prevent the filter screen 707 from sliding out by itself in the non-working state, thereby improving the safety of operation. Due to the design of the filter screen 707, the cleaning process is made simpler, thereby reducing the maintenance cost and improving the usage efficiency of the equipment.

[0029] On one side of the outer wall of the filter screen frame 303, there is a fixed connection with a handle 202. On the outer wall of the filter screen frame 303, there is a connecting plate 404. On one side of the outer wall of the connecting plate 404, there is a reinforcing rib plate 505.

[0030] On the upper surface of the connecting plate 404, there are multiple welding points 101.

[0031] The filter screen frame 303 is welded with channel steel around and in the middle. The filter screen frame 303 is made into a structure that can hold 6 filter screens 707 in 3 layers inside, making the overall filtration more refined.

[0032] When the filter screen 707 needs to be cleaned, the operator can pull out the spring 3 through the handle 202, thereby pushing the filter screen 707 to slide out, facilitating the cleaning of the filter screen 707. The filter screen frame 303 is welded with channel steel around and in the middle. The filter screen frame 303 is made into a structure that can hold 6 filter screens 707 in 3 layers inside, making the overall filtration more refined. The filter screen frame 303 is welded with channel steel around and in the middle. This structure makes the filter screen frame 303 more stable and able to withstand greater pressure, thereby improving the loading capacity of the filter screen 707 and ensuring the stable operation of the equipment. The filter screen frame 303 is made into a structure that can hold 6 filter screens 707 in 3 layers inside. This design makes the filtration effect of the filtration device better. Due to the presence of multiple layers of filter screens 707, when water passes through the filter screens 707, it needs to be filtered multiple times, thereby improving the filtration effect and making the filtered water purer.

[0033] In one embodiment, since three layers of six filters 707 can be placed inside the filter frame 303, water needs to be filtered multiple times during the filtering process, thereby improving the filtering effect and making the filtered water purer. Since the spring 3 is welded with channel steel around and in the middle, the filter frame 303 is more stable and can withstand greater pressure, thereby improving the loading capacity of the filter 707 and ensuring the stable operation of the equipment. Since multiple layers of filter screens 707 can be placed inside the spring 3, when the filter screen 707 needs to be cleaned, the operator can clean multiple filter screens 707 at one time, thereby improving the convenience of operation. Due to the design of the filter frame 303, the cleaning process is simpler, thereby reducing maintenance costs and improving the use efficiency of the equipment.

[0034] The frame of filter 707 is made of lightweight square tube, the stainless steel mesh is riveted and pressed firmly with stainless steel pressing plate, and welded point by point with argon arc welding.

[0035] The frame of the filter 707 is made of lightweight square tube, which together with the stainless steel pressure plate can ensure the stability and durability of the filter 707. The stainless steel pressure plate rivets and presses the stainless steel mesh firmly, ensuring that the filter 707 will not be deformed or broken due to excessive pressure during use.

[0036] In one embodiment, argon arc welding is used point by point to ensure that the various parts of the filter 707 are firmly connected, preventing the filter 707 from breaking or falling off during use, thereby improving the stability of the equipment.

[0037] The inner corners of the spring 3 are welded with reinforced ribs, which reduces the weight of the filter 707 and improves the overall strength.

[0038] In one embodiment, the inner corners of the spring 3 are welded with reinforced ribs. This design can improve the overall strength of the spring 3 without adding too much weight. The presence of the reinforced ribs enables the spring 3 to better disperse the pressure when it is under pressure, preventing the spring 3 from deforming or breaking during use. The reinforced ribs are fixed to the inner corners of the spring 3 by welding, which can ensure that the reinforced ribs will not fall off during use, thereby improving the stability and service life of the device.

[0039] The slideway 808 is a round steel slideway, and the slideway 808 is arranged on one side of the frame of the filter screen 707, which not only ensures that the filter screen 707 is lifted smoothly but also ensures that the two layers of filter screens maintain an appropriate distance between the front and the back.

[0040] In one embodiment, a round steel slideway 808 is provided on one side of the frame of the filter screen 707. This design can ensure smooth lifting of the filter screen 707. The surface of the round steel slideway 808 is smooth, which can reduce the friction force during the lifting process of the filter screen 707, making the operation smoother. The existence of the round steel slideway 808 can also ensure an appropriate spacing between the two layers of filter screens. This spacing allows the water flow to be more evenly distributed on the filter screen 707 when passing through it, improving the filtration effect.

[0041] The willow leaf rail 1, the spring 3 and the willow leaf rail shaft 2 are combined to form a spring-type willow leaf rail. This track is designed as a one-way valve to prevent the filter screen 707 from sliding out by itself in the non-operating state, so as to enhance the operation safety.

[0042] In one embodiment, the willow leaf rail 1, the spring 3 and the willow leaf rail shaft 2 are combined to form a spring-type willow leaf rail. This design allows the filter screen 707 to slide smoothly during operation. In the non-working state, due to the pulling force of the spring 3, the filter screen 707 can be fixed in place and will not slide out by itself. The spring-type willow leaf rail is designed as a one-way valve, which means that the filter screen 707 can only slide in one direction. This can prevent the filter screen 707 from sliding out by itself in the non-working state and enhances the operation safety.

[0043] The inclined plate 8 is provided to facilitate the automatic sliding down of the filter screen 707 when it needs to be cleaned, further improving the operation convenience.

[0044] In one embodiment, through the design of the inclined plate 8, the filter screen 707 can slide down automatically when it needs to be cleaned, which greatly improves the operation convenience and reduces the time and labor intensity of manual cleaning of the filter screen.
