[0002] At present, the metal ions in the recycled industrial wastewater generally need to be removed to avoid the formation of scale in the water-using equipment or pipes. The existing descaling device usually adopts the electrochemical descaling method, which deposits the metal ions in the industrial water on the cathode plate. When the scale is deposited on the cathode plate, the cathode plate is removed for cleaning. However, the regular removal, cleaning and installation of the plate result in low efficiency. Based on the above reasons, a scraper assembly was subsequently manufactured, and the scraper was set on the cathode plate. The scraper was driven by the drive member to move on the cathode plate to scrape off the scale on the cathode plate. However, due to the narrow spacing between the cathode plate and the anode plate, when a large amount of scale is attached to the cathode plate, the scraper cannot complete the scraping of the scale, resulting in slag blockage.

[0024] like Figure 1 , Figure 2 As shown, a descaling device comprises a descaling box 1, a cover plate 2, a driving assembly 3, and a descaling assembly 4; the descaling box 1 is a hollow structure with an opening at the top, the cover plate 2 is detachably mounted at the top opening of the descaling box 1, and the two ends of the descaling box 1 are respectively provided with a water inlet end 11 and a water outlet end 12;

[0025] The driving assembly 3 includes a driving unit 31, a lifting frame 32 and at least two guide columns 33, one end of the lifting frame 32 is fixedly connected to the driving end of the driving unit 31, and the other end is fixedly connected to the guide column 33;

[0026] The descaling assembly 4 includes a fixing member 41, an anode plate 42, a cathode plate 43, an anode wire strip 44, a cathode wire strip 45 and a scraper 46. The anode plate 42 and the cathode plate 43 are spaced apart on the fixing member 41. The anode wire strip 44 and the cathode wire strip 45 are fixedly mounted on the cover plate 2 and are electrically connected to the anode plate 42 and the cathode plate 43, respectively. The scraper 46 is sleeved on the cathode plate 43 and the blade abuts against two surfaces of the cathode plate 43. Both ends of the scraper 46 are fixed to the other end of the guide column 33. The anode plate 42 and the cathode plate 43 are spaced apart by a preset distance.

[0027] like Figure 3 As shown, the driving unit 31 includes a motor 311 , a screw rod 312 and a screw rod nut 313 , one end of the screw rod 312 is rotatably mounted on the motor 311 , and the other end is rotatably mounted on the cover plate 2 , and the screw rod nut 313 is sleeved on the screw rod 312 .

[0028] The lifting frame 32 is an "H"-shaped structure, and the distance between the anode plate 42 and the cathode plate 43 is 50mm-60mm. The scraper 46 is made of metal material and then encapsulated with rubber.

[0029] The anode plate 42 is electrically connected to the anode wire strip 44, and the cathode plate 43 is electrically connected to the cathode wire strip 45. The anode wire strip 44 and the cathode wire strip 45 are respectively connected to an external power source, and together with the anode plate 42 and the cathode plate 43, a conductive loop is formed, and metal ions can be adsorbed through the cathode plate 43. The guide posts 33 can be 2 or 4, and the guide posts 33 pass through the cover plate 2 and are fixedly connected to the scraper 46, driving the scraper 46 to scrape the cathode plate 43 to scrape off the scale on the cathode plate 43.

[0030] When the descaling device starts to work, the cathode plate 43, the anode wire strip 44 and the external power supply are energized. The anode plate 42, the cathode plate 43, the anode wire strip 44 and the cathode wire strip 45 form a conductive loop. The industrial wastewater enters the descaling box 1 from the water inlet end 11, flows through the cathode plate 43 and the anode wire strip 44, and then flows out from the water outlet end 12. During the flow of industrial wastewater, the cathode plate 43 adsorbs metal ions in the wastewater. When the metal ions adsorbed on the cathode plate 43 reach a certain amount, the motor 311 is started, and the motor 311 drives the screw rod 312 to rotate, so that the screw rod nut 313 moves on the screw rod 312, and then drives the lifting frame 32 to move in the direction of the motor 311. The lifting frame 32 drives the scraper 46 to move in the direction of the motor 311 through the guide column 33, and then the scale on the cathode plate 43 is scraped off by the scraper 46, so that the scale falls into the descaling box 1.

[0031] In this way, the descaling device, through the coordinated arrangement of the descaling box 1, the cover plate 2, the driving assembly 3, and the descaling assembly 4, increases the distance between the anode plate 42 and the cathode plate 43 to a preset distance, for example, 60 mm, and at the same time thins the scraper 46 as a whole, thereby increasing the adsorption amount of metal ions on the cathode plate 43 and increasing the scraping space of the scraper, thereby avoiding slag blockage and ensuring the normal operation of the descaling device.

[0032] In one embodiment, the driving assembly 3 further includes a nut locking block 34 , which is fixedly or detachably mounted on the lifting frame 32 and is used to fix the screw nut 313 .

[0033] In this way, by setting the nut locking block 34 , the screw nut 313 can be fixed on the nut locking block 34 , which plays a good fixing effect on the screw nut 313 .

[0034] like Figure 4 As shown, in one embodiment, the descaling device also includes a first water tower 5 and a second water tower 6, which are symmetrically arranged on the cover plate 2, and at least a portion of the cathode wire bar 45 is accommodated in the first water tower 5, and at least a portion of the anode wire bar 44 is accommodated in the second water tower 6. The first water tower 5 is used to cool the cathode wire bar 45, and the second water tower 6 is used to cool the anode wire bar 45.

[0035] In this way, the first water tower 5 has a first water inlet 51 and a first water outlet 52, the first water inlet 51 is connected to an external water source, and the first water outlet 52 is connected to an external water source recovery device; the second water tower 6 has a second water inlet 61 and a second water outlet 62, the second water inlet 61 is connected to an external water source, and the second water outlet 62 is connected to an external water source recovery device. Because a part of the cathode conductor 45 is accommodated in the first water tower 5, the external cooling water enters the first water tower 5 through the first water inlet 51, and then flows back to the water source recovery device from the first water outlet 52, which can play a good heat dissipation role for the cathode conductor 45. Because a part of the anode conductor 44 is accommodated in the second water tower 6, the external cooling water enters the second water tower 6 through the second water inlet 61, and then flows back to the water source recovery device from the second water outlet 62, which can play a good heat dissipation role for the anode conductor 44, and the size of the cooling water flow can be controlled by an external water valve.

[0036] In one embodiment, a slag discharge hole 13 is opened on the side of the descaling box 1, and an electric flange ball valve 14 is provided on the slag discharge hole 13.

[0037] In this way, the slag discharge hole 13 is set at a position that matches the water inlet end 11 on the side of the descaling box 1. After the scale is discharged, the cleaning water enters from the water inlet end 11 and directly flushes the scale out of the slag discharge hole 13, thereby achieving a rapid slag discharge effect. The electric flange ball valve 14 can quickly control the opening and closing of the slag discharge hole 13.

[0038] In one embodiment, the cross section of the descaling box 1 is a U-shaped structure.

[0039] In this way, by making the descaling box 1 into a "V"-shaped structure, and by setting the descaling box 1 into a U-shaped structure, the height of the descaling box 1 is reduced, and the transportation of the entire device is convenient.

[0040] In one embodiment, the descaling box 1 is made of metal material or PP material.

[0041] In this way, if the descaling box 1 is made of PP material, it can effectively prevent scale from corroding the descaling box 1.

[0042] In one embodiment, the descaling device further comprises an air release valve 7 , which is mounted on the cover plate 2 and communicated with the interior of the descaling box 1 .

[0043] In this way, by setting the air release valve 7, the gas inside the descaling box 1 can be quickly discharged through the air release valve 7 to avoid excessive pressure inside the descaling box 1.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
