Description

Technical Field

[0001] This invention relates to the field of electrochemical descaling technology, specifically to an automatic descaling device for electrochemical water treatment. Background Technology

[0002] Currently, traditional chemical treatments for waste heat power generation circulating water only delay corrosion and scaling, failing to improve water quality and even polluting the water. Analysis of the circulating water quality and operation reveals that electrochemical descaling can replace chemical agents, optimizing the treatment of the circulating water. Corrosion inhibitors and scale inhibitors can be completely discontinued, and bactericides only need to be used in summer based on total bacterial count and algae levels. This reduces wastewater discharge and makeup water requirements, significantly minimizing secondary pollution to groundwater and surface water, and alleviating the company's environmental burden. Simultaneously, the significantly reduced risk of scale buildup in the heat exchanger improves condenser heat exchange efficiency, leading to increased power generation and revenue.

[0003] Electrochemical descaling is a method of removing scale using electrochemical principles. In the cathode area of ​​the electrochemical descaling system, calcium and magnesium ions in the water combine with hydroxide and carbonate ions generated by electrolysis to form insoluble calcium hydroxide, magnesium hydroxide, calcium carbonate, and magnesium carbonate precipitates.

[0004] The invention patent with application number CN202310814720.0 and publication number CN116589050A (hereinafter referred to as "Prior Art 1") discloses an automatic descaling electrochemical water treatment device with a horizontal shaft scraper, including a water treatment tank, a tank top provided on the top of the water treatment tank, a waste bin provided in the middle of the bottom of the water treatment tank, and an electrochemical water treatment mechanism provided inside the water treatment tank;

[0005] The specification of prior art 1 discloses an automatic descaling electrochemical water treatment device with a horizontally placed shaft scraper. In use, the screw drives the scraper to scrape off the dirt on the cathode plate. However, in actual application, since the scraper itself cleans the dirt on the cathode plate by making hard contact with it, in order to ensure that the scraper minimizes damage to the cathode plate, it cannot use much force when scraping the cathode plate, thus sacrificing the descaling effect and resulting in a poor descaling effect. Summary of the Invention

[0006] This invention provides an automatic descaling device for electrochemical water treatment, which aims to solve the problem of poor descaling effect of scrapers on cathode plates in the prior art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] An automatic descaling device for electrochemical water treatment includes a mounting box, a scraping device, and a fine treatment device. The mounting box is installed on the ground and is used to install and fix the water treatment device to be descaled inside the mounting box. The scraping device is installed on one side of the mounting box and is used to coarsely treat the scale on the water treatment device inside the mounting box. The fine treatment device is located on the other side of the mounting box and is used to finely treat the scale on the water treatment device inside the mounting box.

[0009] The scraping device includes a housing, a sliding frame, a scraper, and a first driving device. The housing has several through-feed slots on both sides. The first driving device is installed on the housing and connected to the sliding frame, and is used to drive the sliding frame to slide inside the housing. The scraper is installed on the sliding frame, and the number and position of the scraper correspond to the through-feed slots. The scraper is used to scrape off the dirt on the water treatment device after passing through the through-feed slots.

[0010] Furthermore, the water treatment device includes a top plate, a bottom plate, and several electrode plates, which are disposed between the top plate and the bottom plate. The electrode plates are used to adsorb dirt, the bottom plate is used to contact the bottom of the mounting box, and the scraper is used to scrape off the dirt on the electrode plates.

[0011] Furthermore, the installation box is equipped with several guide rods, and the top and bottom plates are equipped with guide holes. The number and position of the guide holes correspond to the number of guide rods, and the guide holes and guide rods are slidably engaged.

[0012] Furthermore, a sliding groove is provided on the top of the mounting box, and a limit strip is provided on the sliding frame. The limit strip passes through the sliding groove and is connected to the sliding frame. The limit strip slides in cooperation with the upper surface of the mounting box. The first driving device is used to drive the limit strip to slide back and forth on the mounting box.

[0013] Furthermore, the installation box is equipped with guide rails, and the sliding frame is slidably connected to the guide rails.

[0014] Furthermore, the fine processing device includes a housing, a three-axis moving assembly, a second drive assembly, a motor, and a grinding head. The three-axis moving assembly is disposed inside the housing, the motor is mounted on the three-axis moving assembly, and the grinding head is connected to the output shaft of the motor. The three-axis moving assembly is used to move the motor on the X, Y, and Z axes via the second drive assembly.

[0015] Furthermore, the three-axis moving assembly includes a first slide rail, a first slide plate, a second slide rail, a fixed plate, and a second slide plate. The first slide rail is disposed inside the housing. The first slide plate is slidably mounted on the first slide rail via a second drive assembly. The second slide rail is disposed on the first slide plate. The fixed plate is slidably mounted on the second slide rail. The second slide plate is slidably mounted on the second slide rail via the second drive assembly. The motor is mounted on the second slide plate. There is a placement groove between the second slide plate and the fixed plate. The placement groove is used to allow space for the motor and the grinding head, so that the motor and the grinding head can slide into the placement groove. The grinding head is used to perform secondary descaling on the electrode plate.

[0016] Furthermore, the motor has a dual-shaft structure, and the grinding head is provided on both output shafts of the motor.

[0017] Furthermore, the scraper has a U-shaped structure, which is used to scrape off the double-sided electrode plate.

[0018] Furthermore, the interior of the installation box is used to install several water treatment devices, each of which corresponds to a scraping device and a fine treatment device.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention mainly includes an installation box, a scraping device, and a fine treatment device. In actual use, the operator places the water treatment device, after adsorbing the dirt, inside the installation box. Then, the first drive device drives the sliding frame to move the scraper towards the inlet groove. During this process, the scraper contacts the water treatment device and scrapes away the scale and dirt. After scraping, the first drive device controls the sliding frame to move away from the water treatment device, at which point the scraper retracts from the inlet groove. Then, the fine treatment device enters the water treatment device and performs a secondary cleaning of the remaining scale and dirt. After cleaning, the fine treatment device resets, completing the cleaning of the scale and dirt on the water treatment device. The water treatment device can then be pulled out and used again. The advantage of this setup is that the scraping by the scraper and the secondary cleaning by the fine treatment device ensure that the scale and dirt on the water treatment device are cleaned better, resulting in a better cleaning effect.

Detailed Implementation

[0027] The present invention will be further described below with reference to embodiments. These embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the protection scope of the present invention.

[0028] Please see Figures 1-4 As shown, this embodiment discloses a descaling device, specifically an electrochemical water treatment automatic descaling device, including a mounting box 101, a scraping device, and a fine treatment device. The mounting box 101 is used to install on the ground, and the water treatment device 102 to be descaled is installed inside the mounting box 101 and fixed therein. The scraping device is installed on one side of the mounting box 101 and is used to coarsely treat the scale on the water treatment device 102 inside the mounting box 101. The fine treatment device is located on the other side of the mounting box 101 and is used to finely treat the scale on the water treatment device 102 inside the mounting box 101.

[0029] The scraping device includes a housing 103, a sliding frame 104, a scraper 105, and a first driving device 106. The housing 101 is provided with several through-feed slots 107 on both sides. The first driving device 106 is installed on the housing 103 and is connected to the sliding frame 104, and is used to drive the sliding frame 104 to slide inside the housing 103. The scraper 105 is installed on the sliding frame 104. The number and position of the scraper 105 correspond to the through-feed slots 107. The scraper 105 is used to scrape off the dirt on the water treatment device 102 after passing through the through-feed slots 107.

[0030] This invention mainly includes a mounting box 101, a scraping device, and a fine treatment device. In actual use, the operator places the water treatment device 102, after adsorbing dirt, inside the mounting box 101. Then, the first driving device 106 drives the sliding frame 104 to move the scraper 105 towards the inlet groove 107. During this process, after the scraper 105 contacts the water treatment device 102, it scrapes off the scale and dirt on the water treatment device 102. After scraping is completed, the first driving device 106 is driven to control the sliding frame 104 to move away from the water treatment device 102. At this time, the scraper 105 moves from the inlet groove 107. Exit at step 07; then use the fine treatment device to enter the water treatment device 102. The fine treatment device performs a secondary cleaning of the residual scale and dirt on the water treatment device 102. After cleaning, the fine treatment device resets, completing the cleaning of the dirt and scale on the water treatment device 102. Pull out the water treatment device 102 and continue using it. The advantage of this setup is that the scraping of the scraper 105 and the secondary cleaning of the water treatment device 102 by the fine treatment device can ensure that the dirt and scale on the water treatment device 102 can be better cleaned, resulting in a better cleaning effect for the water treatment device 102.

[0031] In some embodiments, the water treatment device 102 includes a top plate 108, a bottom plate 109, and a plurality of electrode plates 110. The plurality of electrode plates 110 are disposed between the top plate 108 and the bottom plate 109. The electrode plates 110 are used to adsorb dirt. The bottom plate 109 is used to contact the bottom of the mounting box 101. The scraper 105 is used to scrape off the dirt on the electrode plates 110.

[0032] In actual use, the top plate 108, several electrode plates 110 and the bottom plate 109 are connected to form an integrated structure. The bottom plate 109 is in contact with the bottom surface of the mounting box 101. A cleaning area is formed between two adjacent electrode plates 110. After the scraper 105 enters the cleaning area, it scrapes the two sides of the electrode plate 110.

[0033] In some embodiments, the mounting box 101 is provided with a plurality of guide rods 111, and the top plate 108 and the bottom plate 109 are provided with guide holes 112. The number and position of the guide holes 112 correspond to the number and position of the guide rods 111, and the guide holes 112 are slidably engaged with the guide rods 111.

[0034] In actual use, four guide rods 111 are provided. The four guide rods 111 pass through the four corners of the bottom plate 109 and the top plate 108 to fix the water treatment device 102 as a whole.

[0035] In some embodiments, a sliding groove 113 is provided on the top of the mounting box 101, and a limiting strip 114 is provided on the sliding frame 104. The limiting strip 114 passes through the sliding groove 113 and is connected to the sliding frame 104. The limiting strip 114 slides in cooperation with the upper surface of the mounting box 101. The first driving device 106 is used to drive the limiting strip 114 to slide back and forth on the mounting box 101.

[0036] In actual use, the limiting strip 114 and the sliding frame 104 form a ring structure after being connected. The bottom surface of the limiting strip 114 slides in cooperation with the top of the mounting box 101. As an optional implementation, the first driving device 106 includes a first motor, a first ball screw, and a first screw nut. The first motor is fixedly installed above the mounting box 101, and the screw nut is fixedly installed on the limiting strip 114. One end of the first ball screw is engaged with the screw nut, and the other end is fixedly connected to the output shaft of the first motor. In use, the first motor rotates and drives the first ball screw to rotate. Since the first screw nut and the first ball screw cooperate with each other, the rotation of the first ball screw will drive the limiting strip 114 to slide above the mounting box 101, thereby achieving the purpose of controlling the reciprocating sliding of the limiting strip 114 by the rotation of the first motor.

[0037] In some embodiments, a guide rail 115 is provided inside the mounting box 101, and the sliding frame 104 is slidably connected to the guide rail 115.

[0038] In actual use, the purpose of setting the guide rail 115 is to provide guidance for the sliding frame 104, so that the sliding frame 104 is more stable during the sliding process.

[0039] In some embodiments, the fine processing device includes a housing 116, a three-axis moving assembly, a second drive assembly 117, a motor 118, and a grinding head 119. The three-axis moving assembly is disposed inside the housing 116, the motor 118 is mounted on the three-axis moving assembly, and the grinding head 119 is connected to the output shaft of the motor 118. The three-axis moving assembly is used to move the motor 118 on the X, Y, and Z axes via the second drive assembly 117.

[0040] In actual use, the three-axis moving component controls the motor 118 and the grinding head 119 to move on the X, Y and Z axes; during grinding, the second drive component 117 controls the three-axis moving component to enter between two adjacent electrode plates 110 through the feed groove 107, and the grinding head 119 cleans the two electrode plates 110.

[0041] In some embodiments, the three-axis moving assembly includes a first slide rail 120, a first slide plate 121, a second slide rail 122, a fixing plate 123, and a second slide plate 124. The first slide rail 120 is disposed inside the housing 116. The first slide plate 121 is slidably disposed on the first slide rail 120 via a second drive assembly 117. The second slide rail 122 is disposed on the first slide plate 121. The fixing plate 123 is slidably disposed on the second slide rail 122. The second slide plate 124 is slidably mounted on the second slide rail 122 via the second drive assembly 117. The motor 118 is mounted on the second slide plate 124. A placement groove 125 is provided between the second slide plate 124 and the fixing plate 123. The placement groove 125 is used to make way for the motor and the grinding head 119, allowing the motor and the grinding head 119 to slide into the placement groove 125. The grinding head 119 is used to perform secondary descaling on the electrode plate 110.

[0042] In actual use, the second drive assembly 117 includes a second motor, a second ball screw, a second screw nut, a third motor, a third ball screw, and a third screw nut. The second motor is mounted on the housing 116, and the second screw nut is fixedly mounted on the first slide plate 121. One end of the second ball screw is fixedly connected to the output shaft of the second motor, and the other end is rotatably connected to a connecting strip inside the housing 116 and engages with the second screw nut. The third motor is mounted on the fixing plate 123, and the third screw nut is fixedly mounted on the second slide plate 124. At the bottom, one end of the third ball screw is fixedly connected to the output shaft of the third motor, and the other end is rotatably connected to the fixed plate 123 and cooperates with the third screw nut; a fourth motor 126 is also provided on the first slide plate 121, and a fourth ball screw is rotatably provided on the first slide plate 121. One end of the fourth ball screw is rotatably connected to the first slide plate 121, and the other end is fixedly connected to the output shaft of the fourth motor 126. A fourth screw nut 128 127 is fixedly provided on the fixed plate 123, and the fourth ball screw cooperates with the fourth screw nut 128 127;

[0043] In operation, the operator drives the second motor to rotate, which in turn drives the second ball screw to rotate, thereby causing the first slide plate 121 to slide on the first slide rail 120. When the first slide plate 121 reaches the leftmost feed groove 107, the second motor stops rotating, and the operator drives the third motor to rotate. The third motor in turn drives the third ball screw to rotate, thereby causing the second slide plate 124 to move on the fixed plate 123 towards the electrode plate 110. At the same time, the motor 118 is started to rotate. As the second slide plate 124 moves, the motor 118 performs a fine cleaning of the dirt remaining on the electrode plates 110 on both sides. Then, the operator drives the fourth motor 126 to rotate, and the fourth motor 126 controls the fixed plate 123 to descend. Upon reaching the next height, the fourth motor 126 stops rotating, and the third motor is controlled again, causing the grinding head 119 to clean the electrode plate 110. After the dirt on the electrode plate 110 is cleaned, the second slide plate 124 resets, and the grinding head 119 is located in the placement slot 125 to avoid interference between the grinding head 119 and the feed slot 107 when the first slide plate 121 moves. When the second motor drives the first slide plate 121 to the next feed slot 107 position, it re-enters the cleaning area to clean the electrode plates 110 on both sides. The advantage of this setting is that the electrode plates 110 can be cleaned a second time, avoiding residual dirt and scale on the electrode plates 110, which would affect the adsorption of the electrode plates 110.

[0044] In some embodiments, the motor 118 has a dual-shaft structure, and both output shafts of the motor 118 are provided with the grinding head 119;

[0045] In actual use, the main function of the dual-axis motor 118 is to install two grinding heads 119, which can clean the two electrode plates 110 inside the cleaning area.

[0046] In some embodiments, the scraper 105 has a U-shaped structure, and the U-shaped scraper 105 is used to scrape off the double-sided electrode plate 110.

[0047] In actual use, the U-shaped scraper 105 can scrape the two electrode plates 110 within the cleaning area.

[0048] In some embodiments, the interior of the mounting box 101 is used to install a plurality of water treatment devices 102, each water treatment device 102 corresponding to a scraping device and a fine treatment device.

[0049] In actual use, the significance of each water treatment device 102 corresponding to a scraping device and a fine treatment device is that each water treatment device 102 can be cleaned at the same time without having to maintain the same frequency, which is more conducive to the staff to perform descaling treatment on the water treatment device 102.
