Description

Technical Field

[0001] This utility model relates to the field of electrochemical water treatment technology, and in particular to a descaling device for an electrochemical reaction chamber. Background Technology

[0002] Electrochemical water treatment refers to a technology that, under the influence of an external electric field, utilizes a series of designed chemical reactions, electrochemical processes, or physical processes within specific electrochemical water treatment equipment to generate a large number of free radicals. These free radicals then degrade pollutants in wastewater through their strong oxidizing properties. This is a commonly used technique in industrial water treatment. Electrochemical treatment requires the anode and cathode plates to cooperate in discharging, generating anions, cations, free radicals, and oxide ions. The circulating water to be treated passes between the anode and cathode plates, undergoing purification through chemical reactions involving anions, cations, free radicals, and oxide ions. During this process, a reduction reaction occurs at the cathode plate, continuously releasing hydrogen gas. A localized alkaline environment is created in the cathode plate area, causing calcium and magnesium ions in the circulating water to rapidly precipitate as salts and adhere to the cathode plate, forming a large amount of scale. To prevent excessive scale buildup from affecting the working effect, descaling treatment is necessary.

[0003] In the prior art, the brush assembly or scraper assembly in the descaling device is set up in the electrochemical reaction chamber as part of the whole, and does not have the function of storing the brush assembly or scraper assembly (such as the existing patent CN112551651A). During the electrochemical water treatment process, the brush assembly or scraper assembly will be immersed in the liquid. In this way, the brush assembly or scraper assembly not only occupies a certain amount of reaction space, but also has a shortened service life due to long-term immersion. Utility Model Content

Detailed Implementation

[0037] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 6As shown, this embodiment discloses a descaling device for an electrochemical reaction chamber, including a semi-cylindrical shell 1. The shell 1 has an inlet and an outlet with valves. Inside the shell 1, removable, semi-circular anode plate 2 and cathode plate 3 are arranged along the length direction. Specifically, the inner wall of the shell 1 has slots, and the anode plate 2 and cathode plate 3 are removably placed in the slots at intervals. A rotatable central shaft 4 is provided inside the shell 1, and a brush assembly 5 is arranged on the central shaft 4. The brush assembly 5 is arranged on both sides of the anode plate 2 and cathode plate 3. The brush assembly 5 includes a brush body 5-1, and a detachable shielding shell 5-2 is provided on the outside of the brush body 5-1. The bristles of the brush body 5-1 protrude beyond the shielding shell 5-2. A removable fouling pad 5-3 is provided on the inner wall of the shielding shell 5-2. The brush body 5-1 of the brush assembly 5 faces the anode plate 2 and cathode plate 3.

[0039] L-shaped grooves 6 are provided at both ends of the housing 1. The two ends of the central shaft 4 are slidably disposed within the grooves 6. The bottom end of the groove 6 is set as a semi-circle that mates with the outer wall of the central shaft 4. The bottom end of the groove 6 corresponds to the center position of the anode plate 2 and the cathode plate 3. The center positions of the anode plate 2 and the cathode plate 3 are also provided with corresponding semi-circular groove openings. A safe distance is reserved between the semi-circular groove openings of the anode plate 2 and the cathode plate 3 and the central shaft 4 to avoid friction between the anode plate 2 and the cathode plate 3. One end of the central shaft 4 passes through the groove 6 and is provided with a drive mechanism 7 for driving the central shaft 4 to rotate. The central shaft 4 and the drive mechanism 7 are mounted on the displacement device 8. The drive mechanism 7 can drive the brush body 5-1 to rotate, thereby enabling the brush body 5-1 to scrape and clean the anode plate 2 and cathode plate 3. During cleaning, the splashed dirt will fall into the shielding shell 5-2 and adhere to the dirt-blocking pad 5-3, thus preventing the splashed dirt from soiling the top cover, central shaft 4 and other structures inside the shell 1. The upper side of the inside of the shell 1 is provided with a storage area 1-3. The displacement device 8 can move the central shaft 4 and brush assembly 5 into the storage area 1-3, or move the central shaft 4 and brush assembly 5 from the storage area 1-3 to the semi-circular sliding groove position of the anode plate 2 and cathode plate 3 for descaling and cleaning, thereby ensuring that the brush assembly 5 is kept away from the solution environment during water treatment and avoiding the problem of shortened service life due to immersion.

[0040] The dirt trap 5-3 is made of porous material, such as sponge material, to absorb dirt. The dirt trap 5-3 can be connected to the shielding shell 5-2 by threaded installation for easy replacement.

[0041] like Figure 2 , Figure 4 and Figure 7As shown, the central shaft 4 includes a cylindrical outer shaft 4-1, a square inner cavity 4-2 inside the outer shaft 4-1, and an inner shaft 4-3 that can slide along the axial direction of the square inner cavity 4-2 inside the square inner cavity 4-2. The inner shaft 4-3 is also a square cylinder. The two ends of the outer shaft 4-1 are slidably disposed in the slide groove 6, and one end of the outer shaft 4-1 passes through the slide groove 6 and is connected to the drive mechanism 7.

[0042] A slot 4-1-1 is provided on the peripheral wall of the outer shaft 4-1. The end of the brush body 5-1 of the brush assembly 5 passes through the slot 4-1-1 and is fixedly connected to the inner shaft 4-3 by bolts. In the initial state, the distance between the brush body 5-1 of the brush assembly 5 and one end of the anode plate 2 or cathode plate 3 is...

[0043] The other end of the inner shaft 4-3 is fixedly connected to a connecting rod 4-4. The connecting rod 4-4 can slide axially through the outer shaft 4-1 and is provided with a rotatable sleeve 4-5 by means of a bearing. The sleeve 4-5 and the connecting rod 4-4 will not move axially relative to each other. The sleeve 4-5 is provided with a first telescopic drive member 4-6. The fixed end of the first telescopic drive member 4-6 is fixedly connected to the movable disc seat 4-7. The movable disc seat 4-7 is rotatably connected to the shaft end of the outer shaft 4-1 by means of a bearing. Specifically, the movable disc seat 4-7 can rotate relative to the outer shaft 4-1, but cannot move axially relative to the outer shaft 4-1.

[0044] In this embodiment, a gear seat 4-1-2 is provided at the end of the outer shaft 4-1, and the movable disc seat 4-7 is rotatably connected to the end face of the gear seat 4-1-2 by means of a bearing. This allows the outer shaft 4-1, the inner shaft 4-3, and the connecting rod 4-4 to rotate relative to the sleeve 4-5 and the movable disc seat 4-7.

[0045] like Figure 7 and Figure 8 As shown, the outer peripheral wall of the gear seat 4-1-2 is provided with a groove, and a gear 4-1-3 is fixedly connected in the groove. The drive mechanism 7 includes a rack 7-1, which meshes with the gear 4-1-3. One end of the rack 7-1 is fixedly located at the telescopic end of the second telescopic drive member 7-2. When the second telescopic drive member 7-2 reciprocates, it drives the rack 7-1 to move horizontally reciprocally. In turn, the rack 7-1 drives the gear 4-1-3 to rotate reciprocally. This causes the gear seat 4-1-2, the outer shaft 4-1, the inner shaft 4-3, and the brush assembly 5 to rotate with the inner shaft 4-3 as the center to achieve the scraping cleaning action. The reciprocating telescopic stroke of the second telescopic drive member 7-2 needs to match the rotation angle range of the brush assembly 5.

[0046] In this embodiment, in the initial state, the distance between the brush body 5-1 of the brush assembly 5 and one end of the anode plate 2 or cathode plate 3 is [not specified]. When the first telescopic drive 4-6 is activated to extend, it will push to the left with the movable disc base 4-7 as the fulcrum, that is, pull the sleeve 4-5, the inner shaft 4-3, and the brush assembly 5 to the left (e.g., [not specified]). Figure 7 (as shown on the left), so that the brush body 5-1 facing the left abuts against the right side of the anode plate 2 or cathode plate 3 (as shown on the left). Figure 9 As shown), at this time, the brush body 5-1 bends due to the elasticity of the bristles and tightly adheres to the anode plate 2 or cathode plate 3, while the shielding shell 5-2 is close to the anode plate 2 or cathode plate 3 to shield against splashed dirt. Then, keeping the first telescopic drive 4-6 stationary, the second telescopic drive 7-2 is activated to reciprocate, causing the outer shaft 4-1, inner shaft 4-3, and brush assembly 5 to rotate, thus achieving the scraping cleaning action. Similarly, after cleaning one side of the anode plate 2 or cathode plate 3, the first telescopic drive 4-6 is activated to retract, pulling it to the right around the movable disc base 4-7, thus pushing the sleeve 4-5, inner shaft 4-3, and brush assembly 5 to the right (e.g., Figure 7 (as shown on the right side), so that the brush body 5-1 facing the right side rests against the left side of the anode plate 2 or cathode plate 3, and then a rotating scraping cleaning action is performed.

[0047] like Figures 1 to 3 As shown, the second telescopic drive component 7-2 is fixedly mounted on the connecting frame 7-3. The connecting frame 7-3 is provided with a sliding groove, and the rack 7-1 is slidably mounted on the sliding groove of the connecting frame 7-3. The connecting frame 7-3 is connected to the displacement device 8.

[0048] In this embodiment, the displacement device 8 includes a transverse telescopic member 8-1, which is fixedly mounted on the housing 1. The telescopic end of the transverse telescopic member 8-1 is fixedly connected to the fixed end of the longitudinal telescopic member 8-2, and the telescopic end of the longitudinal telescopic member 8-2 is fixedly connected to the connecting frame 7-3. It should be noted that the slide 6 is L-shaped, comprising a horizontally arranged transverse slide section and a vertically arranged longitudinal slide section. The telescopic trajectory of the transverse telescopic member 8-1 is parallel to the transverse slide section of the slide 6, and the telescopic trajectory of the longitudinal telescopic member 8-2 is parallel to the longitudinal slide section of the slide 6. A guide rail 1-1 is provided on the housing 1, and a guide slider 8-2-1 is fixedly mounted on the fixed end of the longitudinal telescopic member 8-2, which is slidably connected to the guide rail 1-1.

[0049] The shell 1 is provided with a partition 1-2, the position of which matches the bottom edge of the transverse sliding section of the sliding groove 6, and the partition 1-2 and the top plate of the shell 1 form a storage area 1-3.

[0050] In this embodiment, a displacement device 8 is also provided at the other end of the housing 1. The shaft end of the outer shaft 4-1 on this side passes through the housing 1 and is provided with a bearing 9. The outer shaft 4-1 is connected to the inner ring of the bearing 9. The telescopic end of the longitudinal telescopic member 8-2 on this side is connected to the outer ring of the bearing 9 at the shaft end of the outer shaft 4-1. A bearing 9 is also provided on the outer side of the gear seat 4-1-2. The gear seat 4-1-2 is connected to the inner ring of the bearing 9. The outer ring of the bearing 9 is connected to the connecting frame 7-3, thereby providing support for the outer shaft 4-1 with the help of the two bearings 9. The displacement devices 8 on both sides of the housing 1 move synchronously. When the longitudinal telescopic member 8-2 retracts, the outer shaft 4-1 moves upward in the longitudinal slide section of the slide groove 6. When it moves to the transverse slide section of the slide groove 6, the longitudinal telescopic member 8-2 stops, and the transverse telescopic member 8-1 retracts, moving the connecting frame 7-3 and the outer shaft 4-1 along the transverse slide section of the slide groove 6 and retracting them into the storage area 1-3. The housing 1 has openable hatches at the corresponding positions of the storage areas 1-3 to facilitate installation, maintenance and replacement operations.

[0051] In this embodiment, an outer cover 1-4 is also provided on the outside of the slide 6, the drive mechanism 7, and the displacement device 8. The outer cover 1-4 is detachably mounted on the housing 1, thereby forming a sealed environment for the housing 1.

[0052] In this embodiment, the bottom of the housing 1 is inclined, and a drain port with a valve is provided at the lowest point of the inclination. It should be noted that in some cases, circulating water or circulating cleaning fluid can be injected into the housing 1 in conjunction with the brush assembly 5 for cleaning. It should be noted that when injecting circulating water or circulating cleaning fluid, the dirt-blocking pad 5-3 and the shielding shell 5-2 should be removed, leaving only the brush body 5-1.

[0053] In this embodiment, the central shaft 4 and the brush assembly 5 are made of corrosion-resistant materials.

[0054] In this embodiment, the first telescopic drive member 4-6, the second telescopic drive member 7-2, the lateral telescopic member 8-1, and the longitudinal telescopic member 8-2 are electric actuators.

[0055] The operation process of this utility model is as follows:

[0056] Initially, the brush assembly 5 is positioned horizontally, with the central shaft 4 and brush assembly 5 located within the storage area 1-3. When cleaning is required, first, the horizontal telescopic component 8-1 is extended, moving the central shaft 4 to the longitudinal section of the slide groove 6. Then, the vertical telescopic component 8-2 is extended, moving the central shaft 4 to the bottom of the slide groove 6. At this point, the outer shaft 4-1 is also positioned at the center of the semi-circular slide groove opening of the anode plate 2 and cathode plate 3. Next, the first telescopic drive component 4-6 is activated to extend, causing the brush body 5-1 to rest against one side of the anode plate 2 or cathode plate 3. Keeping the first telescopic drive component 4-6 stationary, the second telescopic drive component 7-2 is activated for reciprocating extension and retraction, causing the outer shaft 4-1, inner shaft 4-3, and brush assembly 5 to rotate, thus achieving the scraping cleaning action. Similarly, after cleaning one side of the anode plate 2 or cathode plate 3, the first telescopic drive component 4-6 is activated to retract, causing the brush body 5-1 to rest against the other side of the anode plate 2 or cathode plate 3. Then, the second telescopic drive component 7-2 is activated to perform a reciprocating telescopic movement for scraping and cleaning. After cleaning, the first telescopic drive component 4-6 is reset, causing the brush assembly 5 to move away from the anode plate 2 or cathode plate 3. The second telescopic drive component 7-2 is then reset, placing the brush assembly 5 in a horizontal position away from the storage area 1-3. Finally, the longitudinal telescopic component 8-2 is controlled to retract, retracting the central shaft 4 into the longitudinal groove section of the slide 6, and the transverse telescopic component 8-1 is controlled to retract, retracting the central shaft 4 into the storage area 1-3.

[0057] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
