Description

Technical Field

[0001] This utility model relates to the field of descaling equipment, and in particular to a high-efficiency descaling machine. Background Technology

[0002] Industrial water that is recycled typically requires descaling equipment to remove metal ions to prevent scale buildup in equipment and pipes. Modern descaling machines mostly employ electrochemical descaling, which removes scale by depositing metal ions from the industrial water onto a cathode plate.

[0003] To ensure the descaling process can continue for an extended period, current descaling machines typically have a scraping structure to remove scale deposits on the cathode plate, allowing for continuous scale buildup on the cathode plate surface. However, when the scraped scale falls off, it tends to accumulate on the obstruction structures below the cathode and anode plates, or at the bottom of the tank. This can lead to situations where the accumulated scale comes into contact with both the anode and cathode plates simultaneously, causing them to become conductive. This not only interrupts the descaling process but may also damage the equipment. Therefore, descaling machines with scale scraping structures still require periodic cleaning to prevent the cathode and anode plates from becoming conductive.

[0004] Based on this, the present invention provides a high-efficiency descaling machine to prevent the scale layer scraped off from the cathode plate from conducting through the anode plate and the cathode plate, thereby eliminating the need for periodic manual maintenance and improving its ease of use. Utility Model Content

[0005] Based on this, the present invention provides a high-efficiency descaling machine, including a casing with an enclosed installation space inside, and a descaling device disposed within the installation space. The descaling device is located on the upper part of the installation space, and the portion of the installation space below the descaling device forms a receiving space. The descaling device includes a deposition mechanism, which includes a cathode cylinder and an anode cylinder fixedly disposed on the casing. Both the cathode cylinder and the anode cylinder are cylindrical structures with open ends. Both the cathode cylinder and the anode cylinder are vertically arranged, and the cathode cylinder is sleeved on the anode cylinder. There is a gap between the cathode cylinder and the anode cylinder, forming a receiving gap. The descaling device also includes a scraping mechanism, which includes at least one scraper located within the receiving gap for scraping off the scale layer on the inner wall of the cathode cylinder.

[0006] Furthermore, the housing is provided with a water inlet communicating with the lower end of the installation space, a water outlet communicating with the upper end of the installation space, and a drain outlet communicating with the lower end of the installation space.

[0007] Furthermore, both the cathode cylinder and the anode cylinder are cylindrical, and they are arranged coaxially.

[0008] Furthermore, the scraper is mounted on the housing via a connecting frame. The connecting frame includes a connecting rod vertically disposed within the anode cylinder, the connecting rod being coaxial with the anode cylinder. A mounting base is fixedly connected to the lower end of the connecting rod, and the mounting base partially extends below the receiving interval to form a mounting end. A blade holder is fixedly disposed on the mounting end, extending into the receiving interval. The scraper is mounted on the blade holder, and the blade of the scraper abuts against the inner wall of the cathode cylinder. The top end of the connecting rod extends upward out of the housing to form a connecting section, and the connecting rod is rotatably and sealingly connected to the housing via a rotating sealing structure. The connecting section is used for a driving connection with a driving device disposed on the outer wall of the housing.

[0009] Furthermore, the number of scrapers is two; the mounting base is a horizontally arranged rod shape, with both ends of the mounting base extending below the receiving interval, and the mounting ends are formed at both ends of the mounting base.

[0010] Furthermore, the connecting frame also includes a mounting ring located between the cathode cylinder and the anode cylinder, the mounting ring being arranged around the anode cylinder and coaxial with the anode cylinder, and the upper end of the knife holder being fixedly connected to the mounting ring.

[0011] Furthermore, the number of the descaling devices is multiple and arranged in a rectangular array.

[0012] Furthermore, a mounting bracket is fixedly installed inside the housing, the cathode cylinder is fixedly installed on the mounting bracket and is in communication with the mounting bracket, a negative terminal is fixedly provided on the housing corresponding to the mounting bracket, the negative terminal extends into the installation space and is in communication with the mounting bracket; the top end of the anode cylinder is fixedly installed on the top end of the housing, a positive terminal is fixedly provided on the housing corresponding to the anode cylinder, the positive terminal extends into the installation space and is in communication with the anode cylinder, and the portions of the positive terminal located on the outside of the housing are interconnected through a conductive element.

[0013] Furthermore, the connecting segments located in the same column or row on the housing are combined to form a group of connecting segments. Each connecting segment in the group is equipped with a sprocket, and the sprockets on the connecting segments in the same group are connected to each other by the same transmission chain. The driving device includes a bracket mounted on the outer wall of the housing and a drive motor corresponding to the group of connecting segments. The connecting segments are rotatably mounted on the bracket, the drive motor is mounted on the bracket, and the drive motor is connected to one of the connecting segments in the corresponding group of connecting segments.

[0014] Furthermore, the housing includes a shell with an opening at the top, and a cover that is disposed at the opening of the shell and seals with the shell.

[0015] The principle and effects of this utility model will be further explained below with reference to the above technical solution and the accompanying drawings:

[0016] In this invention, the descaling device completes the descaling process of industrial water. The casing covers the outside of the descaling device and is used to house the descaling device and industrial water. Since the cathode cylinder has a cylindrical structure with open ends and no "bottom sealing structure", when the scraper removes the scale layer on the inner wall of the cathode cylinder, the falling scale layer is not blocked by the "bottom sealing structure" and can smoothly leave the cathode cylinder and fall into the holding space. That is, the scale layer will not accumulate near the cathode cylinder and anode cylinder, which can effectively prevent the falling scale layer from conducting through the cathode cylinder and anode cylinder, thereby achieving the purpose of eliminating the periodic manual maintenance of the descaling machine, improving the descaling efficiency of the descaling machine, and enhancing the ease of use.

[0017] In addition, this utility model places multiple descaling devices within the limited space of the casing, which can significantly increase the processing throughput per unit time, that is, improve the descaling effect on industrial water. At the same time, the descaling devices are arranged in a rectangular array, that is, evenly distributed within the casing, so that the industrial water within the casing can be descaled evenly, further improving the descaling efficiency.

Detailed Implementation

[0026] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0027] like Figure 1-6 A high-efficiency descaling machine includes a casing with an enclosed installation space 13 inside, and a descaling device disposed within the installation space 13. The descaling device is located on the upper part of the installation space 13, and the portion of the installation space 13 below the descaling device forms a receiving space 131. The descaling device includes a deposition mechanism, which includes a cathode cylinder 211 and an anode cylinder 212 fixedly disposed on the casing. Both the cathode cylinder 211 and the anode cylinder 212 are cylindrical structures with open ends. Both the cathode cylinder 211 and the anode cylinder 212 are vertically arranged, with the cathode cylinder 211 sleeved on the anode cylinder 212. There is a gap between the cathode cylinder 211 and the anode cylinder 212 to form a receiving gap. The descaling device also includes a scraping mechanism, which includes at least one scraper 221 located within the receiving gap for scraping off the scale layer on the inner wall of the cathode cylinder 211.

[0028] In this invention, the descaling device is located inside the casing and is used to descale the industrial water entering the casing, that is, to remove metal ions from the industrial water so that the industrial water can be reused. The cathode cylinder 211 and anode cylinder 212 need to be connected to the negative and positive terminals of the power supply, respectively. This allows metal ions in the industrial water to deposit on the inner wall of the cathode cylinder 211 under the influence of the electric field, forming a scale layer. Simultaneously, the scraper 221 scrapes off the scale layer deposited on the inner wall of the cathode cylinder 211, allowing for continuous deposition of metal ions and continuous descaling of the industrial water. The scraped-off scale layer falls downwards into the receiving space 131 and eventually accumulates at the bottom of the receiving space 131.

[0029] In this invention, the descaling device completes the descaling process of industrial water. The casing covers the outside of the descaling device and is used to accommodate the descaling device and industrial water. Since the cathode cylinder 211 has a cylindrical structure with open ends and does not have a "sealed bottom structure", when the scraper 221 scrapes off the scale layer on the inner wall of the cathode cylinder 211, the falling scale layer will not be blocked by the "sealed bottom structure" and can smoothly leave the cathode cylinder 211 and fall into the accommodating space 131. That is, the scale layer will not accumulate near the cathode cylinder 211 and the anode cylinder 212, which can effectively prevent the falling scale layer from conducting through the cathode cylinder 211 and the anode cylinder 212, thereby achieving the purpose of eliminating the periodic manual maintenance of the descaling machine, improving the descaling efficiency of the descaling machine, and enhancing the ease of use.

[0030] In one embodiment, the housing is further provided with a water inlet 111 communicating with the lower end of the installation space 13, a water outlet 112 communicating with the upper end of the installation space 13, and a drain outlet 113 communicating with the lower end of the installation space 13.

[0031] In this embodiment, the water inlet 111 on the casing is connected to the bottom of the installation space 13, and industrial water enters the casing through the water inlet 111. The water outlet 112 is connected to the top of the installation space 13, and industrial wastewater that has undergone descaling treatment leaves the casing through the water outlet 112. The drain outlet 113 is connected to the bottom of the installation space 13, and the scale layer accumulated at the bottom of the installation space 13 can be flushed away from the casing by periodically opening the drain outlet 113.

[0032] In one embodiment, both the cathode cylinder 211 and the anode cylinder 212 are cylindrical, and the cathode cylinder 211 and the anode cylinder 212 are arranged coaxially.

[0033] In this embodiment, the coaxial cathode cylinder 211 and anode cylinder 212 enable the electric field lines to radiate uniformly in the radial direction. The distance between the inner wall of the cathode cylinder 211 and the outer wall of the anode cylinder 212 is constant, which can ensure that the electric field intensity is consistent throughout the reaction space. This can avoid local electric field distortion and make the path of directional migration of metal ions under the drive of the electric field more stable, thereby reducing ion retention or displacement.

[0034] In one embodiment, the scraper 221 is mounted on the housing via a connecting frame. The connecting frame includes a connecting rod 222 vertically disposed within the anode cylinder 212. The connecting rod 222 is coaxially disposed with the anode cylinder 212. A mounting base 223 is fixedly connected to the lower end of the connecting rod 222. The mounting base 223 extends partially below the receiving interval to form a mounting end. A blade holder 24 is fixedly disposed on the mounting end and extends into the receiving interval. The scraper 221 is mounted on the blade holder 24, and the blade of the scraper 221 abuts against the inner sidewall of the cathode cylinder 211. The top end of the connecting rod 222 extends upward out of the housing to form a connecting section 2221. The connecting rod 222 is rotatably and sealingly connected to the housing via a rotating sealing structure 36. The connecting section 2221 is used for driving connection with a driving device disposed on the outer sidewall of the housing.

[0035] In this embodiment, the driving device is driven to connect to the connecting section 2221, and is used to drive the connecting rod 222 to rotate around its own axis. This drives the blade holder 24 and the scraper 221 mounted on the blade holder 24 to rotate in a circumferential direction. At this time, the scraper 221, whose blades abut against the inner wall of the cathode cylinder 211, can scrape off the scale deposited on the inner wall of the cathode cylinder 211. Since the mounting base 223 is always rotating during the descaling process, even if the scale falls onto the mounting base 223, the impact of the industrial water inside the housing on the mounting base 223 as the mounting base 223 rotates can wash off the scale. Therefore, scale will not accumulate on the mounting base 223.

[0036] In this embodiment, the connecting rod 222 can be rotatably connected to the housing through a rotary sealing structure such as a rotary shaft lip seal, mechanical seal, or packing seal. Preferably, the upper end of the anode cylinder 212 is sealed to the housing, meaning the upper end of the anode cylinder 212 is closed. After industrial water enters the housing, the air at the upper end of the anode cylinder 212 cannot be discharged, and industrial water cannot enter the upper end of the anode cylinder 212. In this way, the rotary sealing structure 36 between the connecting rod 222 and the housing at the upper end of the anode cylinder 212 will not be submerged in industrial water during use, which increases the range of options for the rotary sealing structure 36 and increases its service life.

[0037] In one embodiment, there are two scrapers 221; the mounting base 223 is a horizontally arranged rod shape, with both ends of the mounting base 223 extending below the receiving gap, and the mounting ends are formed at both ends of the mounting base 223.

[0038] In this embodiment, the mounting base 223 is rod-shaped. While ensuring the mounting base 223 can support the knife holder 24, its volume is minimized, thereby reducing its obstruction of falling scale. Preferably, the mounting base 223 is round rod-shaped, allowing scale to slide off more easily.

[0039] In one embodiment, the connecting frame further includes a mounting ring 225 located between the cathode cylinder 211 and the anode cylinder 212. The mounting ring 225 is arranged around the anode cylinder 212 and coaxially with the anode cylinder 212. The upper end of the knife holder 24 is fixedly connected to the mounting ring 225.

[0040] In this embodiment, the mounting ring 225 fixes the upper end of the blade holder 24 together, which can support the blade holder 24 and effectively prevent the blade holder 24 from deflecting during rotation. In other words, it can effectively prevent the scraper 221 from deflecting during operation and effectively ensure the scraper 221's scraping effect on the scale layer on the cathode cylinder 211.

[0041] In one embodiment, the number of descaling devices is multiple and arranged in a rectangular array.

[0042] In this embodiment, placing multiple descaling devices within the confined space of the casing can significantly increase the processing throughput per unit time, thereby improving the descaling effect on industrial water. At the same time, the descaling devices are arranged in a rectangular array, that is, evenly distributed within the casing, which allows for uniform descaling of the industrial water within the casing, further improving the descaling efficiency.

[0043] In one embodiment, a mounting bracket 4 is fixedly installed inside the housing. The cathode cylinder 211 is fixedly installed on the mounting bracket 4 and is in communication with the mounting bracket 4. A negative terminal 5 is fixedly provided on the housing corresponding to the mounting bracket 4. The negative terminal 5 extends into the installation space 13 and is in communication with the mounting bracket 4. The negative terminal 5 is sealed and fitted with the housing. The top end of the anode cylinder 212 is fixedly installed on the top end of the housing. A positive terminal 6 is fixedly provided on the housing corresponding to the anode cylinder 212. The positive terminal 6 extends into the installation space 13 and is in communication with the anode cylinder 212. The positive terminal 6 is sealed and fitted with the housing. The portion of the positive terminal 6 located on the outside of the housing is interconnected through a conductive element 7.

[0044] In this embodiment, the housing needs to be made of insulating material, and the mounting bracket 4 needs to be made of conductive material. It serves as the mounting structure for the cathode cylinder 211. After the cathode cylinder 211 is mounted on the mounting bracket 4 through welding, bolt connection, or other structures, it can be fixed in the housing and connected to the mounting bracket 4. Since the mounting bracket 4 connects the negative terminal 5 and the cathode cylinder 211, the cathode cylinder 211 and the negative terminal of the external power supply can be connected by connecting the negative terminal 5 to the negative terminal of the external power supply. The top end of the anode cylinder 212 can be mounted on the housing through a bolt connection structure. For example, a horizontal flange is provided at the top end of the anode cylinder 212, and the flange is fixed to the housing using a bolt connection structure. Since the positive terminal 6 connected to the anode cylinder 212 is interconnected through a conductive element 7, the anode cylinder 212 and the positive terminal of the external power supply can be connected by connecting the conductive element 7 to the positive terminal of the external power supply.

[0045] In one embodiment, connecting segments 2221 located in the same column or row on the housing are combined to form a group of connecting segments. Each connecting segment 2221 in the group is equipped with a sprocket 33, and the sprockets 33 on the connecting segments 2221 in the same group are connected to each other by the same transmission chain 34. The driving device includes a bracket 31 installed on the outer wall of the housing and a drive motor 32 provided for the corresponding connecting segment group. The connecting segments 2221 are rotatably installed on the bracket 31, and the drive motor 32 is installed on the bracket 31 and is drivenly connected to one of the connecting segments 2221 in the corresponding connecting segment group.

[0046] In this embodiment, the connecting segment 2221 can be rotatably mounted on the bracket 31 via the bearing structure 35.

[0047] In this embodiment, the drive motor 32 is driven to connect to one of the connecting segments 2221 in the corresponding connecting segment group, and is used to drive the connecting segment 2221 to rotate around its own axis. At the same time, since all the connecting segments 2221 in the connecting segment group are connected by a transmission chain 34, the drive motor 32 can drive all the connecting segments 2221 in the same connecting segment group to rotate synchronously, thereby realizing the descaling operation of the scraping mechanism where the connecting segment 2221 is located.

[0048] In one embodiment, the housing includes a housing 11 with an opening at the top, and a cover 12 that covers the opening of the housing 11 and seals with the housing 11.

[0049] In this embodiment, the housing consists of a housing 11 and a cover 12, and the housing can be opened by removing the cover 12. Preferably, the connecting rod 222 extends through the cover 12 to the outside of the housing, and the anode cylinder 212, the drive device, the positive terminal 6, and the negative terminal 5 are all mounted on the cover 12.

[0050] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
