Description

Technical Field

[0001] The invention relates to the technical field of electrochemical water treatment, in particular to a descaling brush driving device for an electrochemical reaction chamber. Background Art

[0002] With the continuous expansion of industrial production, the contradiction between human beings and the natural environment has become increasingly prominent, people's demands for the environment have become increasingly strong, and industrial wastewater discharge standards have become increasingly stringent. The electrochemical treatment technology of industrial wastewater uses electrochemical water treatment equipment to produce a series of electrochemical reactions in wastewater through the anode and cathode electrolysis process to eliminate and transform harmful substances in the water to meet national drainage standards or industrial water standards. This is a resource-saving and environmentally friendly advanced technology. In recent years, with the enhancement of people's awareness of environmental protection and water conservation, electrochemical wastewater treatment technology has made great progress with its unique advantages.

[0003] However, practice has shown that the existing electrochemical reaction chamber has the problem of deterioration of water quality when used for water treatment. This is because the cathode plates used in large and medium-sized electrochemical reaction chambers are large and have uneven surfaces. The current scraping and descaling process uses a descaling brush to orbit around the inner cathode cylinder to remove scale. The scale layer on the surface of the cathode cylinder is not completely removed, and each time the scale is scraped, the scale layer remaining in the low-lying area is squeezed by the scraper, and the density, hardness and resistance value of the scale layer increase. As the number of scraping times increases, the density of the residual scale layer increases, the resistance increases, and the effective utilization rate of the current is low, resulting in a decrease in the quality of the produced water.

DETAILED DESCRIPTION

[0027] A descaling brush driving device for an electrochemical reaction chamber comprises a reaction chamber body; Figure 1 -Attached Figure 6 As shown, the reaction chamber body includes a cylindrical inner cathode cylinder 1 located in the middle, an outer cathode cylinder 2 coaxial with the inner cathode cylinder 1 is arranged on the outer side thereof, a plurality of electrode cylinders coaxial with the inner cathode cylinder 1 and the outer cathode cylinder 2 and spaced apart are arranged between the inner cathode cylinder 1 and the outer cathode cylinder 2, the electrode cylinder is composed of cathode cylinders 3 and anode cylinders 4 arranged in a staggered manner, and the anode cylinders 4 and the cathode cylinders 3, the inner cathode cylinder 1 and the outer cathode cylinder 2 are arranged in a staggered manner; two cylindrical descaling brush bodies 45 placed opposite to each other are arranged on the outer side of the inner cathode cylinder 1, the inner side of the outer cathode cylinder 2, and the inner and outer sides of the cathode cylinder 3, and brush wires 5 are arranged on the circumferential surface of the descaling brush body 45;

[0028] As attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5As shown, a screw rod 6 is vertically arranged in the middle of the inner cavity of the inner cathode cylinder 1, and the lower part of the screw rod 6 is rotatably supported on the lower part of the inner cathode cylinder 1 through a bidirectional thrust ball bearing 7, and a screw rod brake mechanism is arranged at the bottom end of the screw rod 6; a spline shaft 8 threadedly connected to the screw rod 6 is arranged on the outer side of the screw rod 6, and a spline sleeve 9 is sleeved on the outer side of the spline shaft 8, and the spline sleeve 9 is rotatably supported on the top of the inner cathode cylinder 1 through a bearing seat 10, and a spline sleeve gear 11 located below the bearing seat 10 is fixedly assembled on the bottom of the spline sleeve 9, and the bearing seat 10 is provided with a spline sleeve gear 11. 0 is provided with a reduction motor 12 with a base fixedly connected thereto, and a reduction motor gear 13 meshing with a spline sleeve gear 11 is fixedly mounted on the output shaft of the reduction motor 12; an inverted U-shaped descaling brush mounting bracket 14 is fixedly sleeved on the top end of the spline shaft 8, and the upper part of the descaling brush body 45 is rotatably passed through the descaling brush mounting bracket 14, and the top end of the descaling brush body 45 is fixedly mounted with a descaling brush gear 15 located above the descaling brush mounting bracket 14, and the spline shaft 8 is transmission-connected to the descaling brush gear 15 through a transmission mechanism.

[0029] Under the condition of configuring a reduction motor 12, the present invention realizes the reciprocating cyclic motion process of the descaling brush body 45, namely, straight down-directional rotation-straight up-standby, and realizes the self-rotation motion of the descaling brush body 45. The spline shaft 8 is an external spline and internal nut structure; the nut in the center hole of the spline shaft 8 cooperates with the screw 6 to form a self-locking screw nut pair, and the purpose of its self-locking is: when the spline shaft 8 rotates at a certain position, it can drive the screw 6 that can rotate freely to rotate, and prevent the spline shaft 8 from linearly displacing along the screw 6. The screw brake mechanism can switch the screw 6 at will between rotating with the spline shaft 8 and not rotating with the spline shaft 8. The reduction motor 12 is selected to drive the spline sleeve 9 through the gear pair, so that the spline shaft 8 can stably stop at any position.

[0030] When the descaling brush body 45 is lifted and lowered and revolves, the reduction motor 12 drives the spline sleeve 9 to rotate through the gear pair, and the spline sleeve 9 drives the spline shaft 8 to rotate. At the same time, the screw 6 is stationary under the action of the screw brake mechanism, and the spline shaft 8 rotates and descends with the descaling brush body 45, thereby realizing the downward movement of the descaling brush body 45. When the descaling brush body 45 descends to the specified position, the screw brake mechanism releases the screw 6, and the screw 6 rotates with the spline shaft 8, thereby realizing the directional rotation of the spline shaft 8, that is, the revolving of the descaling brush body 45. When the spline shaft 8 rotates to the specified angle (that is, the scale layer is completely removed), the reduction motor 12 stops, the screw brake mechanism brakes the screw 6, the reduction motor 12 rotates in the opposite direction, the screw 6 does not move, and the spline shaft 8 rotates and rises with the descaling brush body 45, thereby realizing the upward movement of the descaling brush body 45. The descaling brush mounting frame 14 moves upward to a designated position, and the reduction motor 12 stops, and the above cycle is repeated until the next working time, and this cycle repeats itself.

[0031] As attached Figure 2As shown, the screw brake mechanism includes a brake groove 16 opened at the bottom of the side of the screw 6 and a brake box 17 fixedly connected to the inner wall of the inner cathode cylinder 1, and the brake box 17 is adjacent to the side wall of the screw 6 and is slidably penetrated by a brake pin 18 that is opposite to the brake groove 16. The side of the brake pin 18 is integrally provided with an outer limit ring 19 located on the outside of the brake box 17 and an inner limit ring located inside the brake box 17. A return spring 20 is arranged between the outer limit ring 19 and the brake box 17 and is sleeved on the brake pin 18. An electromagnetic switch 21 is fixedly penetrated through the side wall of the brake box 17 away from the screw 6.

[0032] During braking, the return spring 20 drives the brake pin 18 to move until the brake pin 18 is pressed into the brake groove 16, thereby limiting the position of the screw rod 6 and preventing the screw rod 6 from rotating with the spline shaft 8; when the brake is released, the electromagnetic switch 21 generates suction to pull the brake pin 18 out, so that the brake pin 18 leaves the brake groove 16, and the screw rod 6 can rotate with the spline shaft 8 in this state. This structural design allows the state of whether the screw rod 6 rotates with the spline shaft 8 to be changed according to the operating requirements, and is convenient for remote control.

[0033] As attached Figure 5 , Attachment Figure 6 As shown, the transmission mechanism includes a fixed inner gear ring 22 arranged at the top of the inner side wall of the inner cathode cylinder 1, a first transmission shaft 23 located inside the descaling brush body 45 is vertically rotated and penetrated on one side of the descaling brush mounting frame 14, a first transmission gear 24 located below the descaling brush mounting frame 14 and meshing with the fixed inner gear ring 22 is fixedly mounted on the bottom end of the first transmission shaft 23; a second transmission gear 25 located above the descaling brush mounting frame 14 is fixedly mounted on the top end of the first transmission shaft 23; a second transmission shaft 26 is rotatably penetrated on the top end of the spline shaft 8, and the second transmission shaft 26 The lower part is fixedly equipped with the III transmission gear 27, and the III transmission gear 27 and the II transmission gear 25 are meshed with the II intermediate gear 29 through the I intermediate gear 28; the top of the II transmission shaft 26 is fixed with a plurality of I connecting rods 30 which are evenly distributed along the circumferential direction and located above the descaling brush gear 15, and the outer ends of the I connecting rods 30 are commonly fixed with a rotating inner gear ring 31, which is respectively meshed with the two descaling brush gears 15 installed at the outer ends of the descaling brush mounting frame 14, and the descaling brush gears 15 located on the same side are meshed in sequence from the outside to the inside.

[0034] When the descaling brush body 45 rotates, the reduction motor 12 rotates forward, and the descaling brush mounting bracket 14 descends to the specified position and rotates at that position (assuming clockwise rotation). Since the first transmission gear 24 at the lower end of the first transmission shaft 23 is engaged with the fixed inner gear ring 22 installed on the upper part of the inner cathode cylinder 1, the first transmission shaft 23 rotates counterclockwise. Because the II transmission gear 25 at the upper end of the I transmission shaft 23 is meshed with the I intermediate gear 28, the I intermediate gear 28 rotates clockwise, the II intermediate gear 29 rotates counterclockwise, the III transmission gear 27 at the lower end of the II transmission shaft 26 and the rotating inner gear ring 31 rotate clockwise together, the first descaling brush gear 15 installed on the outer end of the descaling brush mounting frame 14 rotates clockwise, and the first descaling brush body 45 installed on the outer end of the descaling brush mounting frame 14 rotates clockwise. Since the descaling brush body 45 is installed on the descaling brush mounting frame 14 and revolves clockwise together with the descaling brush mounting frame 14, and what is removed is the scale layer on the inner surface of the outer cathode cylinder 2, it is achieved that the cutting end of the brush filament 5 always cuts into the processed surface to peel off and cut the scale layer. The second descaling brush gear 15 meshes with the first descaling brush gear 15, so that the second descaling brush gear 15 and the descaling brush body 45 driven by it on the outer surface of the cathode cylinder rotate counterclockwise, and the outer surface of the cathode cylinder is stripped and cut. Similarly, the remaining descaling brushes all achieve stripping and cutting.

[0035] When the descaling brush mounting bracket 14 moves downward to the designated position under the drive of the reduction motor 12, that is, when the descaling brush body 45 moves downward and extends into the designated position of the reaction chamber body, the first transmission gear 24 is just fully meshed with the fixed inner gear ring 22. When the descaling brush body 45 makes an orbital motion, the first transmission shaft 23 also makes an orbital motion. At the same time, the first transmission shaft 23 rotates under the meshing action of the first transmission gear 24 and the fixed inner gear ring 22, and the rotation speed N 传1自 Calculated by formula (a):

[0036] N 传1自 =i 1 *N 公 (a)

[0037] In the formula, i 1 is the transmission ratio between the fixed inner gear ring 22 and the first transmission gear 24, which is calculated by formula (b), N 公 is the revolution speed of the first transmission shaft 23;

[0038] i 1 =Z 内1 / Z 传1 (b)

[0039] In the formula, Z 内1 is the number of teeth of the fixed inner gear ring 22; Z 传1 is the number of teeth of the first transmission gear 24;

[0040] The second transmission shaft 26 is rotatably mounted on the top of the spline shaft 8 and is coaxial with the spline shaft 8. The two ends of the second transmission shaft 26 are respectively provided with a third transmission gear 27 and a rotating internal gear ring 31. The second transmission gear 25 is meshed with the third transmission gear 27 through the first intermediate gear 28 and the second intermediate gear 29, and the transmission ratio is i 2 Calculated by formula (c):

[0041] i 2 =Z 传2 / Z 传3 (c)

[0042] In the formula, Z 传2 is the number of teeth of the II transmission gear 25; Z 传3 is the number of teeth of the III transmission gear 27;

[0043] The rotation speed N of the second transmission shaft 26 传2 Calculated by formula (d):

[0044] N 传2 =i 2 *N 传1自 (d)

[0045] The rotating inner gear ring 31 is meshed with the descaling brush gear 15 on the left and the descaling brush gear 15 on the right respectively; the descaling brush body 45 on the left and the descaling brush body 45 on the right are arranged in an offset arrangement in the axial direction, and together complete the circumferential and axial non-leakage cutting of the inner surface of the outer cathode cylinder 2. The rotation speed N of the descaling brush body 45 on the left is 刷左1 With the descaling brush 45N on the right 刷右1 Calculated by formula (e):

[0046] N 刷左1 =N 刷右1 =i 3 *N 传2 =N 传2 *Z 内2 / Z 左刷1 =N 传2 *Z 内2 / Z 右刷1 (e)

[0047] In the formula, Z 内2 Z is the number of teeth of the rotating inner gear ring 31; 左刷1 Z is the number of teeth of the descaling brush gear 15 on the left side; 右刷1 is the number of teeth of the descaling brush gear 15 located on the right side; and Z 左刷1 =Z 右刷1 =Z 刷1 , so we have:

[0048] N 刷左1 =N 刷右1 =i 刷1 *N 公 =i 1 *i 2 *i 3 *N 公 =Z 内1 / Z 传1 *Z 传2 / Z 传3 *Z 内2 / Z 刷1 *N 公 (f)

[0049] In the embodiment, the number of the cathode cylinders 2 is two, that is, the descaling brush bodies 45 located on the left and the descaling brush bodies 45 located on the left are both four. 刷1 , Z 刷2 , Z 刷3 , Z 刷4 The gear teeth of brush 1, brush 2, brush 3 and brush 4 are respectively, and brush 1, brush 2, brush 3 and brush 4 are four descaling brush bodies 45 arranged from outside to inside; i 刷1 、i 刷2 、i 刷3 、i 刷4 are the transmission ratios of brush 1, brush 2, brush 3, and brush 4 respectively, then i 刷1 =i 1 *i 2 *i 3 ,i 刷2 =Z 刷1 / Z 刷2 ,i 刷3 =Z 刷 / Z 刷3 ,i 刷4 =Z 刷3 / Z 刷4 , N 刷左2 =N 刷右2 =i 刷2 *N 刷1 , N 刷左3 =N 刷右3 =i 刷3 *N 刷2 , N 刷左4 =N 刷右4 =i 刷3 *N 刷3

[0050] According to the above process, the descaling brush body 45 can be made to rotate at a set speed.

[0051] When the descaling brush body 45 moves, the revolution direction, revolution speed, self-rotation direction, and self-rotation speed of the descaling brush body 45 acting on the same descaling surface are the same, and the following two conditions must be met at the same time: (A) The self-rotation direction requirements of the descaling brush body 45, that is, when the descaling brush body 45 revolves around the center line of the reaction chamber, the self-rotation direction of the descaling brush body 45 ensures that the cutting end of the brush wire 5 always cuts into the processed surface to peel and cut the scale layer. (B) The self-rotation and revolution speed requirements of the descaling brush body 45 on the circumferential direction of the inner cathode cylinder 1, the outer cathode cylinder 2, or the cathode cylinder 3 without missing any cutting.

[0052] In order to satisfy condition (A), the rotation direction of the descaling brush body 45 for removing the scale layer on the inner surface of the outer cathode cylinder 2 and the cathode cylinder 3 is the same as the revolution direction of the descaling brush body 45, that is, both are clockwise or counterclockwise; the rotation direction of the descaling brush body 45 for removing the scale layer on the outer surface of the inner cathode cylinder 1 and the cathode cylinder 3 is opposite to the revolution direction of the descaling brush body 45, that is, when it revolves in the clockwise direction, it rotates in the counterclockwise direction, and when it revolves counterclockwise, it rotates clockwise, thereby achieving stripping and brushing.

[0053] In order to satisfy condition (B), when the driving device of the present invention is used for a telescopic brush filament 5 (i.e., the brush filament 5 can be extended and retracted along the radial direction of the descaling brush body 45), the values ​​of the rotation speed of the brush filament 5 and the sliding speed of the brush filament 5 on the surface of the cathode cylinder 3, the inner cathode cylinder 1 or the outer cathode cylinder 2 satisfy formula (g):

[0054]

[0055] Where n is the rotation speed of the brush 5, in revolutions per second; r ym is the maximum distance from the cutting end of the brush wire 5 to the brush rod axis during the effective cutting stage, in mm, and r ym ≤r, r is calculated by formula (h); v is the sliding speed of the brush filament 5 on the surface of the cathode cylinder 3, the inner cathode cylinder 1 or the outer cathode cylinder 2, and the sliding speed is the sum of the rotation linear speed and the revolution linear speed of the brush filament 5, and the unit is mm / s; α is the angle between two adjacent brush filaments 5, and the unit is degree; ξ is the minimum expansion and contraction amount of the brush filament 5 in the effective cutting stage, and the unit is mm;

[0056] r≥s+w (h)

[0057] Wherein, s is the distance from the cutting end of the brush wire 5 to the surface of the cathode tube 3, the inner cathode tube 1 or the outer cathode tube 2, in mm; w is the maximum fluctuation of the surface of the cathode tube 3, the inner cathode tube 1 or the outer cathode tube 2, in mm.
