Description

Technical Field

[0001] This utility model relates to the field of cooling water treatment, and in particular to a box-type industrial cooling water treatment device. Background Technology

[0002] Industrial cooling water typically contains scale-forming ions such as calcium and magnesium. As the cooling water is continuously circulated and used, the water gradually evaporates, and the concentration of scale-forming ions in the water continuously increases. When the concentration of these ions exceeds their solubility in water, scale such as calcium carbonate and magnesium hydroxide will form and adhere to the heat exchangers, pipe inner walls, and other parts of the cooling system.

[0003] To better apply electrochemical descaling technology and meet the cooling water treatment needs of industrial sites, a box-type industrial cooling water treatment device has been developed. This device integrates the cathode, anode, and related control system required for electrochemical descaling into a single box, offering advantages such as compact structure, small footprint, and easy installation. It can be easily connected to industrial cooling water pipelines. In existing box-type cooling water treatment devices, a large number of hydroxide ions are generated near the cathode, making the local solution highly alkaline. This disrupts the balance between alkalinity and hardness in the water, causing scale-forming ions such as calcium and magnesium to migrate towards the cathode area under electrostatic attraction, forming precipitates such as calcium carbonate and magnesium hydroxide, which then adhere to the cathode surface, leading to difficulties in cleaning. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a box-type industrial cooling water treatment device.

[0005] The box-type industrial cooling water treatment device provided by this utility model adopts the following technical solution:

[0006] A box-type industrial cooling water treatment device includes a box, electrode tubes, and an electrode switching mechanism. Two sets of partitions are spaced apart inside the box, forming a descaling zone with the box. An inlet and an outlet are provided on the side wall of the descaling zone. The electrode tubes are disposed within the descaling zone, with both ends connected to the spaced-apart partitions. The top of the electrode tube passes through the upper partition, and one end of the electrode tube contacts the electrode switching mechanism. At least two electrode tubes are provided.

[0007] Optionally, the pole-switching mechanism includes a drive assembly, a sleeve, a first connecting rod, and a ring. The drive assembly drives the sleeve to rotate. The two ends of the first connecting rod are respectively connected to the sleeve and the ring. A plurality of first connecting rods are arranged in a ring along the axis of the sleeve. The ring includes a cathode region, an anode region, and two sets of insulating regions. The two ends of the cathode region and the anode region are fixedly connected to the insulating regions. A cathode connecting wire is provided on the outer wall of the cathode region, and an anode connecting wire is provided on the outer wall of the anode region. Both the cathode connecting wire and the anode connecting wire are made of elastic material. The cathode connecting wire and the anode connecting wire are respectively connected to the negative and positive terminals of a power supply. One end of the electrode tube passing through the partition abuts against the inner wall of the ring.

[0008] Optionally, the inner wall of the ring is provided with an annular groove, and one end of the electrode tube passing through the partition is rotatably connected to a conductive wheel. The conductive wheel is inserted into the annular groove and abuts against the inner wall of the annular groove.

[0009] Optionally, the drive assembly includes a motor, a shaft, a gear, and a gear. The motor is fixed to the top of the housing. The output end of the motor is connected to one end of the shaft, and the other end of the shaft is connected to the gear. The gear and gear mesh with each other, and gear is fixedly connected to the top of the sleeve.

[0010] Optionally, a descaling assembly is also included, comprising a second motor, a screw, a nut sleeve, a second connecting rod, and a scraper sleeve. The second motor is located at the bottom of the lower partition, and its output end is connected to the screw. The nut sleeve is mounted on the screw. The number of the second connecting rod and the scraper sleeve is the same as the number of the electrode tubes. One end of the second connecting rod is fixed to the nut sleeve, and the other end of the second connecting rod is fixed to the scraper sleeve. The scraper sleeve is located on the surface of the electrode tube.

[0011] Optionally, the electrode tubes are provided with 6.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. By designing a switching mechanism, the polarity of the electrode tube can be changed. When the polarity changes, the original anode becomes the cathode and the original cathode becomes the anode. The redox environment on the electrode surface is reversed. For deposits attached to the electrode, such as metal oxides, their oxidation and reduction states will change accordingly under the new electrode polarity, thereby reducing the chemical stability of the deposits and making them easier to peel off from the electrode surface.

[0014] 2. The sleeve is driven to rotate 180° forward by the drive assembly. The sleeve drives the ring to rotate forward through the connecting rod, so that the cathode area and the anode area abut against different electrode tubes respectively. After a period of time, the drive assembly drives the sleeve to rotate 180° in reverse, realizing the switching of the polarity of the electrode tubes. The cathode connection wire and anode connection wire on the outer wall of the ring are made of elastic material, which will not affect the rotation of the ring.

[0015] 3. The combination of the annular groove and the conductive wheel ensures contact between the electrode tube and the cathode or anode area while minimizing friction and preventing damage to the electrode tube.

[0016] 4. By starting motor two, the screw is driven to rotate. As the screw rotates, the nut sleeve will move the connecting rod two and the scraper sleeve at the end of the connecting rod two in the vertical direction under the action of the screw, so as to remove the scale on the outer wall of the electrode tube and avoid the time-consuming and laborious manual cleaning.

[0024] Example 1

[0025] Reference Figure 1-2 A box-type industrial cooling water treatment device includes a box 1, electrode tubes 2, and an electrode switching mechanism 6. Two sets of partitions 3 are spaced apart inside the box 1, forming a descaling zone with the box 1. The side wall of the descaling zone is provided with an inlet 4 and an outlet 5. The electrode tubes 2 are placed in the descaling zone, and both ends of the electrode tubes 2 are connected to the spaced partitions 3. The top of the electrode tubes 2 passes through the upper partition 3, and one end of the electrode tubes 2 that passes through contacts the electrode switching mechanism 6. At least two electrode tubes 2 are provided. By designing the electrode switching mechanism 6, the polarity of the electrode tubes 2 can be changed. When the polarity is changed, the original anode becomes the cathode, and the original cathode becomes the anode. The redox environment on the electrode surface is reversed. For deposits such as metal oxides attached to the electrode, their oxidized and reduced states will change accordingly under the new electrode polarity, thereby reducing the chemical stability of the deposits and making them easier to peel off from the electrode surface.

[0026] The pole-switching mechanism 6 specifically includes a drive assembly 610, a sleeve 620, a connecting rod 630, and a ring 640. The drive assembly 610 drives the sleeve 620 to rotate. The two ends of the connecting rod 630 are respectively connected to the sleeve 620 and the ring 640. Several connecting rods 630 are arranged in a ring along the axis of the sleeve 620. The ring 640 includes a cathode region 641, an anode region 642, and two sets of insulating regions 643. The two ends of the cathode region 641 and the anode region 642 are fixedly connected to the insulating regions 643. The outer wall of the cathode region 641 is provided with a cathode connecting wire 644, and the outer wall of the anode region 642 is provided with an anode connecting wire 645. Both the cathode connecting wire 644 and the anode connecting wire 645 are spring-loaded. Made of elastic material, the cathode connection wire 644 and the anode connection wire 645 are respectively connected to the negative and positive terminals of the power supply. One end of the electrode tube 2 passes through the partition 3 and abuts against the inner wall of the ring 640. The drive assembly 610 drives the sleeve 620 to rotate 180° in the forward direction. The sleeve 620 drives the ring 640 to rotate in the forward direction through the connecting rod 630, so that the cathode area 641 and the anode area 642 abut against different electrode tubes 2 respectively. After a period of time, the drive assembly 610 drives the sleeve 620 to rotate 180° in the reverse direction, realizing the back-and-forth switching of the polarity of the electrode tube 2. The cathode connection wire 644 and the anode connection wire 645 on the outer wall of the ring 640 are both made of elastic material, which will not affect the rotation of the ring 640.

[0027] In this embodiment, the drive assembly 610 includes a motor 611, a rotating shaft 612, a gear 613, and a gear 614. The motor 611 is fixed to the top of the housing 1. The output end of the motor 611 is connected to one end of the rotating shaft 612, and the other end of the rotating shaft 612 is connected to the gear 613. The gear 613 and the gear 614 mesh with each other. The gear 614 is fixedly connected to the top of the sleeve 620. The motor 611 can rotate 180° forward and reverse, thereby realizing the forward and reverse rotation of the ring 640 through the transmission of the gear 613 and the gear 614.

[0028] Example 2

[0029] An annular groove 646 is formed on the inner wall of the ring 640. One end of the electrode tube 2, which passes through the partition 3, is rotatably connected to a conductive wheel 210. The conductive wheel 210 is inserted into the annular groove 646 and abuts against the inner wall of the annular groove 646. The advantage of this design is that it prevents poor contact caused by long-term friction between the electrode tube 2 and the inner wall of the ring 640. The cooperation between the annular groove 646 and the conductive wheel 210 can ensure that the electrode tube 2 is in contact with the cathode area 641 or the anode area 642 while minimizing friction and preventing damage to the electrode tube 2.

[0030] Example 3

[0031] The bottom of the housing 1 is also equipped with a descaling component 7, which includes a second motor 710, a screw 720, a nut sleeve 730, a second connecting rod 740, and a scraper sleeve 750. The second motor 710 is located at the bottom of the lower partition 3, and the output end of the second motor 710 is connected to the screw 720. The nut sleeve 730 is located on the screw 720. The number of the second connecting rod 740 and the scraper sleeve 750 is the same as the number of electrode tubes 2. One end of the second connecting rod 740 is fixed to the nut sleeve 730, and the other end of the second connecting rod 740 is fixed to the scraper sleeve 750. The scraper sleeve 750 is located on the surface of the electrode tube 2. By starting the second motor 710, the screw 720 is driven to rotate. While the screw 720 is rotating, the nut sleeve 730 will be driven by the screw 720 to move the second connecting rod 740 and the scraper sleeve 750 at the end of the second connecting rod 740 in the vertical direction, thereby removing the scale from the outer wall of the electrode tube 2 and avoiding the time-consuming and laborious manual cleaning.

[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
