Description

Technical Field

[0001] This utility model relates to the field of cooling circulating water technology, and in particular to an automatic dosing device for a cooling circulating water system. Background Technology

[0002] Cooling water circulation systems play a vital role in industrial production. As a key component ensuring normal equipment operation and controlling temperature, the stability of the water quality has a decisive impact on the safety and operational efficiency of the entire system. Through continuous circulation, cooling water can experience scaling, corrosion, and microbial growth due to evaporation and concentration. Therefore, it is necessary to periodically add scale inhibitors, corrosion inhibitors, and bactericides to the system to maintain water quality stability and ensure normal system operation.

[0003] Especially in the core process of chemical dosing, existing dosing devices have gradually revealed a series of obvious limitations and technical problems when handling different concentrations and types of chemical solutions. For example, utility model patent CN214990328U discloses an automatic chemical dosing device for a circulating water system, including a chemical storage tank connected to the water supply pipeline of a cooling tower, which is used for chemical dosing via a dosing device; a pH monitoring sensor and a conductivity monitoring sensor installed on the pipeline valve group of the cooling tower; an intelligent electrical control box, which includes a pH meter and a conductivity meter, with the pH meter electrically connected to the pH monitoring sensor and the conductivity meter electrically connected to the conductivity monitoring sensor; the cooling tower is connected to an external water source through a pipeline equipped with a water supply solenoid valve, which is electrically connected to the intelligent electrical control box; the cooling tower is also equipped with a sewage discharge pipeline, which is equipped with a sewage discharge valve, and the sewage discharge valve is electrically connected to the intelligent electrical control box. This device enables automatic detection of circulating water quality and automatic dosing of chemicals based on the detection results, stopping automatically once the water quality meets the standards. It has a high level of automation, effectively reducing labor costs and improving dosing efficiency.

[0004] However, in practical applications, existing technologies still have many shortcomings. Specifically, existing automatic dosing devices are not conducive to sufficient stirring of the chemical solution during the dosing process, resulting in uneven mixing and affecting the dispersion and effectiveness of the chemicals. Furthermore, the lack of an effective stirring structure or an unreasonable stirring method can easily lead to chemical sedimentation and blockage of the dosing pipeline, further affecting dosing accuracy and system stability. Simultaneously, when dealing with complex conditions involving high concentrations or the synergistic dosing of multiple chemicals, existing devices struggle to achieve rapid and uniform mixing of the chemical solution, thus affecting the overall dosing effect and potentially causing water quality imbalances, increasing system operational risks. Therefore, to address the many shortcomings of existing technologies, we urgently need an innovative automatic dosing device for cooling circulating water systems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic dosing device for a cooling circulating water system, which solves the problem in the prior art that it is not convenient to fully stir the liquid medicine, resulting in uneven mixing of the liquid medicine and affecting the dispersion effect and efficacy of the medicine.

[0006] To achieve the above objectives, this utility model provides an automatic dosing device for a cooling circulating water system, including a housing, a filter plate slidably connected to the inner side of the housing, and a top plate connected to the top of the housing;

[0007] A stirring rod is rotatably connected to the top side of the filter plate, and a drive motor is fixedly connected to the top side of the top plate by bolts. The top end of the stirring rod passes through the top plate and is connected to the output shaft of the drive motor. A hydraulic cylinder is fixedly connected to the bottom side of the box by bolts, and the output shaft of the hydraulic cylinder passes through the bottom of the box and is fixedly connected to the bottom of the filter plate. A filter frame is fixedly connected to the bottom side of the filter plate by bolts, and a pump body is fixedly connected to the outer wall of the box by bolts. The inlet of the pump body is connected to one side of the filter frame.

[0008] The bottom of the box is fixedly connected to both sides of the bottom plate, and the door is rotatably connected to the outer side of the box via a hinge.

[0009] The pump body has a telescopic hose connected to its inlet, and one end of the telescopic hose passes through one side of the bearing filter plate and the filter frame, connecting them.

[0010] The bottom end of the stirring rod is rotatably connected to the top of the carrying filter plate via a rotating shaft, and the top end of the stirring rod passes through the top plate via a bearing sleeve. Side plates are fixedly connected to both the bottom sides of the top plate and the top sides of the carrying filter plate, and adsorption packing is fixedly connected to both sides of the two side plates.

[0011] The top plate has sliders fixedly connected to both sides, and both sliders are slidably connected to the inner wall of the box through a groove.

[0012] The filter plate is fixedly connected to two sides with sliding blocks, and the two sliding blocks are slidably connected to the inner wall of the box through a sliding groove.

[0013] This invention discloses an automatic dosing device for a cooling circulating water system. Through the design of a drive motor and agitator, it effectively solves the problem of insufficient chemical mixing in existing technologies, improving the dispersion and effectiveness of the chemicals in the water and avoiding pipeline blockage caused by chemical sedimentation. Secondly, by using a hydraulic cylinder to drive the support filter plate up and down, it achieves stirring of the chemical solution at different depths. This not only improves the uniformity of the chemical mixture but is also particularly suitable for high-concentration or multi-chemical co-dosing situations, meeting the water quality control needs under complex operating conditions and reducing the risk of water quality imbalance caused by uneven chemical mixing. Furthermore, the filter frame located at the bottom of the support filter plate effectively prevents pump blockage while achieving efficient dosing, further ensuring the stability and reliability of the system and reducing maintenance frequency and operating costs.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 ,

[0023] An automatic dosing device for a cooling circulating water system includes a housing 1, a filter plate 10 slidably connected to the inner side of the housing 1, and a top plate 8 connected to the top of the housing 1.

[0024] A stirring rod 9 is rotatably connected to the top side of the filter plate 10, and a drive motor 5 is fixedly connected to the top side of the top plate 8 by bolts. The top end of the stirring rod 9 passes through the top plate 8 and is connected to the output shaft of the drive motor 5. A hydraulic cylinder 3 is fixedly connected to the bottom side of the housing 1 by bolts, and the output shaft of the hydraulic cylinder 3 passes through the bottom of the housing 1 and is fixedly connected to the bottom of the filter plate 10. A filter frame 11 is fixedly connected to the bottom side of the filter plate 10 by bolts, and a pump body 7 is fixedly connected to the outer wall of the housing 1 by bolts. The inlet of the pump body 7 is connected to one side of the filter frame 11.

[0025] First, the required chemicals and water are injected into the tank 1. Then, the drive motor 5 is started. The output shaft of the drive motor 5 drives the stirring rod 9 to rotate through the transmission connection, thereby stirring the chemical solution. At the same time, the hydraulic cylinder 3 is started. Its output shaft passes through the bottom of the tank 1 and is fixedly connected to the bottom of the support filter plate 10, pushing the support filter plate 10 up and down, so that the stirring rod 9 can stir the chemical solution at different heights, ensuring that the chemical solution is mixed evenly. When a dosing operation is required, the pump 7 is started and connects to the inside of the tank 1 through the filter frame 11, drawing out the fully stirred and filtered chemical solution from the tank 1, thus implementing the automatic dosing process of the cooling circulating water system. During this process, the filter frame 11 prevents the pump 7 from clogging, ensuring the smooth progress of the entire dosing operation.

[0026] Furthermore, both sides of the bottom of the housing 1 are fixedly connected to the base plate 2, and the outer side of the housing 1 is rotatably connected to the door 4 via a hinge. During the installation and maintenance of the equipment, the base plate 2 provides a stable support foundation, enabling the entire device to be placed firmly on the ground or on a support, preventing it from shifting due to vibration during operation. At the same time, the door 4 can be opened and closed via a hinge, making it convenient for operators to inspect, clean, or replace parts of the internal structure of the housing 1, simplifying the daily maintenance process and improving the operability and maintenance convenience of the equipment.

[0027] Furthermore, a telescopic hose 6 is connected to the inlet of the pump body 7, and one end of the telescopic hose 6 passes through one side of the supporting filter plate 10 and the filter frame 11, connecting them. During the dosing process, the pump body 7 draws the pre-filtered liquid from the filter frame 11 through the telescopic hose 6. The design of the telescopic hose 6 ensures stable connection even when the supporting filter plate 10 moves up and down, ensuring continuous and uninterrupted liquid delivery. This structure effectively improves the flexibility and stability of the pumping process, avoids sealing failure or pipeline breakage caused by rigid connections, and ensures that the liquid has undergone preliminary filtration before entering the pump body, reducing the risk of clogging.

[0028] Furthermore, the bottom end of the stirring rod 9 is rotatably connected to the top of the supporting filter plate 10 via a rotating shaft, and the top end of the stirring rod 9 passes through the top plate 8 via a bearing sleeve. Side plates 12 are fixedly connected to both the bottom sides of the top plate 8 and the top sides of the supporting filter plate 10, and adsorption packing 13 is fixedly connected to both sides of each side plate 12. The stirring rod 9 can rotate freely under the drive of the drive motor 5 and stir the liquid. Simultaneously, when the supporting filter plate 10 moves up and down under the drive of the hydraulic cylinder 3, the stirring rod 9 maintains relative sliding with the top plate 8 through the bearing sleeve at the top, without affecting the stirring action, ensuring the continuity and efficiency of the stirring action. In addition, the adsorption packing 13 on the side plates 12 can adsorb impurities and micro-bubbles in the liquid during stirring, improving the purity and mixing uniformity of the liquid, further ensuring the quality of drug addition.

[0029] Furthermore, sliders 14 are fixedly connected to both sides of the top plate 8, and both sliders 14 are slidably connected to the inner wall of the housing 1 through grooves 15. During the up-and-down movement of the filter plate 10 with the hydraulic cylinder 3, the top plate 8, as the main structure supporting the drive motor 5 and the agitator rod 9, has its sliders 14 sliding synchronously along the grooves 15 on the inner wall of the housing 1, thereby achieving guiding and limiting functions. This structure effectively enhances the stability of the top plate 8 during lifting and lowering, preventing instability in the drive motor 5 or the agitator rod 9 due to swaying, thus improving the overall reliability and safety of the equipment operation.

[0030] Furthermore, sliding blocks 16 are fixedly connected to both sides of the carrying filter plate 10, and both sliding blocks 16 are slidably connected to the inner wall of the housing 1 through sliding grooves 15. When the hydraulic cylinder 3 pushes the carrying filter plate 10 to move up and down, the sliding blocks 16 slide along the sliding grooves 15 on the inner wall of the housing 1, playing a good guiding and supporting role, ensuring that the carrying filter plate 10 runs smoothly during the lifting and lowering process, without tilting or jamming. This structural design not only improves the movement accuracy of the carrying filter plate 10, but also reduces frictional resistance, extends the service life of the equipment, and provides a basic guarantee for the stable stirring of the stirring rod 9 at different heights.

[0031] In summary:

[0032] First, the required medicine and water are injected into the tank 1. Then, the drive motor 5 is started, and its output shaft drives the stirring rod 9, which is fixed to the top plate 8, to rotate through a transmission connection, thereby stirring the medicine solution inside the tank 1. At the same time, the hydraulic cylinder 3 is started, and its output shaft passes through the bottom of the tank 1 and is fixedly connected to the bottom of the support filter plate 10, pushing the support filter plate 10 to move up and down, so that the stirring rod 9 can stir the medicine solution in multiple layers at different heights, improving the mixing uniformity. The top side of the support filter plate 10 is rotatably connected to the stirring rod 9 through a rotating shaft. The top of the top plate 8 is pierced by a bearing sleeve to ensure stable stirring during lifting and lowering. Furthermore, sliders 14 are fixed on both sides of the top plate 8, forming a sliding connection between the sliders 14 and the grooves 15 on the inner wall of the housing 1. When the filter plate 10 moves up and down with the hydraulic cylinder 3, the sliders 14 slide along the grooves 15, providing a guiding and limiting function, thus enhancing the stability of the top plate 8. Simultaneously, sliding blocks 16 are also provided on both sides of the filter plate 10, similarly slidably connected to the inner wall of the housing 1 via the grooves 15, further improving its movement accuracy and reducing... Low frictional resistance; after mixing, when the dosing operation is required, the pump body 7 starts, and its inlet is connected to the filter frame 11 located at the bottom of the support filter plate 10 through the telescopic hose 6. The pre-filtered medicine is drawn from the filter frame 11 to avoid clogging of the pump body 7 due to insufficient filtration. During this process, the design of the telescopic hose 6 allows the support filter plate 10 to move up and down while maintaining a stable connection with the pump body 7, improving the flexibility and reliability of the delivery process. In addition, side plates 12 are fixed between the bottom sides of the top plate 8 and the top sides of the support filter plate 10. Adsorption packing 13 is provided on both sides of the side plates 12, which can effectively adsorb impurities and micro bubbles in the medicine during the mixing process, further improving the purity and mixing uniformity of the medicine, thereby ensuring the dosing effect. The entire device is supported by the bottom plates 2 fixed on both sides of the bottom of the box 1 to ensure the stability of the equipment and avoid displacement or vibration during operation. At the same time, the door 4 is connected to the outside of the box 1 by a hinge, which is convenient for daily maintenance personnel to open, inspect, clean or replace internal parts, improving the operation convenience and maintainability of the equipment.By coordinating the drive motor 5 and the stirring rod 9, and combining the hydraulic cylinder 3 to drive the filter plate 10 up and down, the medicine solution is stirred at different heights, significantly improving the uniformity of the mixture and solving the problems of insufficient stirring and easy sedimentation in the prior art. Secondly, the design of the telescopic hose 6 between the filter frame 11 and the pump body 7 ensures that the medicine solution has completed preliminary filtration before entering the pump body 7, effectively preventing the pump body 7 from clogging. At the same time, the flexible connection of the telescopic hose 6 adapts to the up and down movement of the filter plate 10, enhancing the stability and continuity of the system. Thirdly, the sliding connection structure between the slider 14 and the chute 15, and between the sliding block 16 and the chute 15, respectively provides good guidance and limiting for the top plate 8 and the filter plate 10, improving the smoothness of each component during operation. The device offers several advantages: firstly, it improves the stability and precision of the dosing process, reducing shaking or jamming; secondly, the adsorption packing 13 on the side plate 12 adsorbs impurities and gases in the liquid during stirring, helping to improve the quality of the liquid and further ensuring the stability and consistency of the dosing effect; thirdly, the base plate 2 provides a stable support foundation for the entire device, and the door 4 greatly facilitates daily maintenance and cleaning, improving the operability and maintenance efficiency of the equipment. In summary, this device not only overcomes the shortcomings of traditional dosing equipment in terms of uneven stirring, liquid blockage, and unstable operation, but also achieves high efficiency, stability, and intelligence in the liquid treatment process through various structural optimization designs. It is particularly suitable for industrial scenarios with high water quality requirements, such as chemical, power, and metallurgical industries, and has broad application prospects and promotional value.
