Description

Technical Field

[0001] This utility model belongs to the field of chemical circulating water technology, and specifically relates to a filtration device for chemical circulating water with a cleaning structure. Background Technology

[0002] In chemical production processes, circulating water systems play a vital role, providing cooling, lubrication, and other functions for various chemical equipment to ensure their normal operation. However, circulating water often contains various impurities, such as particulate matter, microorganisms, algae, and other suspended solids. If these impurities are not filtered out in time, they can cause many problems for the circulating water system.

[0003] On the one hand, impurities can easily accumulate inside pipes and equipment, leading to pipe blockage, reduced flow area, increased flow resistance of circulating water, reduced cooling efficiency of the system, and in severe cases, even affect the normal operation of chemical production, causing production stoppage and economic losses. On the other hand, the presence of impurities may also cause wear and corrosion to key components of equipment, such as impellers of water pumps and heat exchange surfaces of heat exchangers, shortening the service life of equipment and increasing the cost of equipment maintenance and replacement.

[0004] Currently, common chemical circulating water filtration devices have certain shortcomings in terms of filtration effect and cleaning and maintenance. After long-term use, impurities tend to adhere to and accumulate on the filter screen or filter media of many traditional filtration devices, resulting in a decrease in filtration efficiency. Existing cleaning methods are mostly cumbersome, requiring manual disassembly of the equipment for cleaning, which not only consumes a lot of manpower and time, but also requires stopping the equipment, making continuous filtration impossible. Therefore, developing a chemical circulating water filtration device with a highly efficient cleaning structure is of great practical significance.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model is a filtration device for chemical circulating water with a cleaning structure, including a main pipe, a connecting pipe installed at one end of the main pipe for connecting to an external water inlet pipe, and the lower end of the main pipe connected to an external water outlet pipe. A filter screen is installed on the inner wall of the main pipe, with the highest horizontal position of the filter screen lower than the connecting pipe. A conveying pipe is installed at the upper end of the inner cavity of the main pipe, with the lowest end of the conveying pipe higher than the filter screen. A conveying component is installed inside the conveying pipe, and a cleaning component is installed at the lower end of the conveying component. A storage component is installed on one side of the main pipe, with the upper end of the storage component communicating with the inside of the conveying pipe.

[0007] The filter screen is shaped like a frustum, with the upper diameter of the filter screen being larger than the lower diameter. The conveying pipe is coaxially arranged with the filter screen so that impurities blocked at the upper part of the filter screen can gather towards the center of the filter screen.

[0008] The conveying assembly includes a power unit, which is installed at the upper end of the main pipeline. A transmission rod is installed at the drive end of the power unit. The transmission rod is located inside the main pipeline and is coaxially arranged with the filter screen. A spiral blade is installed around the transmission rod, and the diameter of the spiral blade is the same as the diameter of the inner cavity of the conveying pipeline.

[0009] The cleaning assembly includes multiple connecting rods, one end of which is installed at the lower end of the transmission rod. A cleaning plate is installed at one end of each connecting rod, and several brushes are evenly installed on each cleaning plate, with the brushes in close contact with the surface of the filter screen.

[0010] The storage component includes a storage box, which is installed on one side of the main pipeline. A discharge hopper is installed on the upper end of the storage box, and one end of the discharge hopper is connected to the upper end of the conveying pipeline. The storage box communicates with the interior of the upper end of the conveying pipeline through the discharge hopper. A sealing cap is threaded on the lower end of the storage box.

[0011] The spiral blades are evenly provided with several drainage holes.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model uses a filter screen to block impurities in the circulating chemical water. The power component drives the transmission rod and spiral blades to rotate, which transports the impurities on the filter screen upward into the conveying pipeline. Subsequently, the impurities enter the storage tank through the discharge bin, realizing centralized storage of impurities for subsequent unified treatment. This prevents impurities from mixing back into the circulating water or causing other problems in the filtration device. It also eliminates the need for manual disassembly and cleaning of the equipment, enabling the device to perform continuous filtration.

[0014] 2. This utility model uses the rotation of the transmission rod to drive the connecting rod installed at the lower end to rotate, which in turn drives the brush to clean the surface of the filter screen and remove impurities attached to the filter screen. During the circulating water filtration process, the cleaning component moves with the movement of the transmission component, continuously cleaning the filter screen to prevent impurities from accumulating on the filter screen, ensuring the filtration effect of the filter screen and reducing the problem of decreased filtration efficiency caused by impurity accumulation.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] Please see Figures 1-4 As shown:

[0025] This embodiment provides a filtration device for chemical circulating water with a cleaning structure, including a main pipe 1, a connecting pipe 2 installed at one end of the main pipe 1 for connecting to an external water inlet pipe 3, and an external water outlet pipe 4 connected to the lower end of the main pipe 1. A filter screen 5 is installed on the inner wall of the main pipe 1, with the highest horizontal position of the filter screen 5 lower than that of the connecting pipe 2. A conveying pipe 6 is installed at the upper end of the inner cavity of the main pipe 1, with the lowest end of the conveying pipe 6 higher than that of the filter screen 5. A conveying component 7 is installed inside the conveying pipe 6, and a cleaning component 8 is installed at the lower end of the conveying component 7. A storage component 9 is installed on one side of the main pipe 1, with the upper end of the storage component 9 communicating with the interior of the conveying pipe 6.

[0026] In practical use, the external water inlet pipe 3 transports the chemical circulating water to the connecting pipe 2, and then the connecting pipe 2 transports the chemical circulating water to the main pipe 1. The chemical circulating water flows downward in the main pipe 1. When the water flows through the filter screen 5 on the inner wall of the main pipe 1, various impurities in the water are intercepted by the filter screen 5, thereby achieving the filtration of the circulating water. The filtered water can continue to flow downward and be discharged through the connection between the lower end of the main pipe 1 and the external water outlet pipe 4, entering the subsequent circulation system. The impurities blocked by the filter screen 5 and entering the main pipe 1 can be transported from the filter screen 5 to the conveying pipe 6 by the conveying component 7. Then, they enter the storage component 9 through the part of the conveying pipe 6 that communicates with the storage component 9, realizing the storage of impurities for subsequent unified treatment of impurities, and preventing impurities from mixing into the circulating water again in the filtration device or causing other problems.

[0027] Furthermore, when the conveying component 7 rotates, it will drive the cleaning component 8 installed at the lower end to rotate, cleaning the surface of the filter screen 5. During the circulating water filtration process, the cleaning component 8 moves with the conveying component 7, continuously cleaning the filter screen 5 to prevent impurities from accumulating on the filter screen 5, ensuring the filtration effect of the filter screen 5, and reducing the problem of decreased filtration efficiency caused by impurity accumulation.

[0028] like Figure 1-3 As shown, the filter screen 5 is shaped like a frustum, and the diameter of the upper end of the filter screen 5 is larger than the diameter of the lower end. The conveying pipe 6 is coaxially arranged with the filter screen 5 so that the impurities blocked at the upper end of the filter screen 5 can gather towards the center of the filter screen 5, thereby facilitating the conveying component 7 to carry the impurities into the conveying pipe 6, and then convey the impurities to the storage component 9 through the conveying pipe 6.

[0029] like Figure 1-5 As shown, the conveying assembly 7 includes a power component 10, which is installed at the upper end of the main pipe 1. A transmission rod 11 is installed at the drive end of the power component 10. The transmission rod 11 is located in the inner cavity of the main pipe 1 and is coaxially arranged with the filter screen 5. A spiral blade 12 is installed around the transmission rod 11. The diameter of the spiral blade 12 is the same as the inner diameter of the conveying pipe 6. Several drainage holes 19 are evenly opened on the spiral blade 12. Thus, driven by the power component 10, the transmission rod 11 and the spiral blade 12 are rotated, which conveys the impurities on the filter screen 5 upward into the conveying pipe 6. During this process, the drainage holes 19 can return the water in the impurities to the main pipe 1. The impurities conveyed into the conveying pipe 6 enter the storage assembly 9 through the part of the conveying pipe 6 that communicates with the storage assembly 9 for storage, so as to be processed uniformly later.

[0030] The power component 10 includes, but is not limited to, an electric motor.

[0031] like Figure 3-5As shown, the cleaning assembly 8 includes multiple connecting rods 13. One end of each connecting rod 13 is installed at the lower end of the transmission rod 11. A cleaning plate 14 is installed at one end of each connecting rod 13. Several brushes 15 are evenly installed on the cleaning plate 14. The brushes 15 are in close contact with the surface of the filter screen 5. Thus, the rotation of the transmission rod 11 through the connecting rod 13 can drive the cleaning plate 14 to rotate, thereby driving the brushes 15 to clean the surface of the filter screen 5, removing impurities attached to the filter screen 5, and preventing the accumulation of impurities from affecting the filtration efficiency of the filter screen 5.

[0032] like Figure 1 , Figure 4 , Figure 6 As shown, the storage component 9 includes a storage box 16, which is installed on one side of the main pipeline 1. A discharge bin 17 is installed on the upper end of the storage box 16. One end of the discharge bin 17 is connected to the upper end of the conveying pipeline 6. The storage box 16 communicates with the interior of the upper end of the conveying pipeline 6 through the discharge bin 17. A sealing cover 18 is threaded on the lower end of the storage box 16. When the spiral blade 12 carries impurities into the upper end of the conveying pipeline 6, the impurities will enter the storage box 16 through the discharge bin 17 for storage, so that the impurities can be uniformly processed later. When it is necessary to remove the impurities, the sealing cover 18 can be rotated to open and the impurities inside the storage box 16 can be removed. The discharge bin 17 is set with a certain tilt angle, which facilitates the impurities to fall into the storage box 16.

[0033] The working principle of the chemical circulating water filtration device with a cleaning structure provided by this utility model is as follows: Three external water inlet pipes transport the chemical circulating water to the connecting pipe 2, which in turn transports it to the main pipe 1. The chemical circulating water flows downwards within the main pipe 1. When the water flows through the filter screen 5 on the inner wall of the main pipe 1, various impurities in the water are intercepted by the filter screen 5, thus achieving filtration of the circulating water. The filtered water can continue to flow downwards and is discharged through the connection between the lower end of the main pipe 1 and the external water outlet pipe 4, entering the subsequent circulation system. Impurities blocked by the filter screen 5 and entering the main pipe 1 can be driven by the power component 10, which drives the transmission rod 11 and the spiral blade 12 to rotate. The impurities on the filter screen 5 are conveyed upwards into the conveying pipe 6. Subsequently, the impurities enter the storage box 16 through the discharge hopper 17 to store the impurities for subsequent unified processing. This prevents the impurities from mixing back into the circulating water or causing other problems in the filtration device. When the transmission rod 11 rotates, it drives the connecting rod 13 installed at the lower end to rotate, which drives the brush 15 to clean the surface of the filter screen 5 and remove the impurities attached to the filter screen 5. During the circulating water filtration process, the cleaning component 8 moves with the movement of the conveying component 7, continuously cleaning the filter screen 5 to prevent a large amount of impurities from accumulating on the filter screen 5, ensuring the filtration effect of the filter screen 5 and reducing the problem of decreased filtration efficiency caused by impurity accumulation.

[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
