Description

Technical Field

[0001] The invention relates to the technical field of electrochemical water treatment, in particular to a brush wire telescopic descaling 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 shows 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 descaling brushes with ordinary brush structures have large cutting widths and insufficient profiling performance. The current scraping descaling method uses a scraper to squeeze the scale layer remaining in the low-lying areas once, and the density, hardness, and resistance of the scale layer increase once. As the number of scraping 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. Based on this, it is necessary to invent a brush wire telescopic descaling device for an electrochemical reaction chamber, which can move parallel to the surface of the plate while rotating, and can remove dirt in the low-lying areas of the cathode plate surface, so as to achieve the purpose of completely removing scale on the uneven cathode plate surface. Summary of the invention

[0004] In order to solve the problem of deterioration of water quality of produced water during water treatment in an existing electrochemical reaction chamber, the present invention provides a brush wire telescopic descaling device for an electrochemical reaction chamber.

[0009] Furthermore, the upper dimension of the brush rod shell is smaller than its lower dimension, and the upper and lower parts of its inner wall are connected by a conical guide surface; the bottom of the inner wall of the brush rod shell is a conical positioning surface; the upper part of the brush rod shell is integrally provided with a guide boss facing inward; the upper dimension of the brush core rod is smaller than its lower dimension, and the upper and lower parts of its side are connected by a guide cone surface whose shape matches the conical guide surface of the brush rod shell, the bottom of the side of the brush core rod is a positioning cone surface that matches the shape of the conical positioning surface of the brush rod shell, and one side of the upper part of the side of the brush core rod is a guide plane that fits the guide boss; the bottom of the convex ribs are jointly provided with an annular water guide hole, and the bottom surface of the brush core rod is provided with a plurality of drainage holes connected to the water guide hole.

[0011] When the brush wire is in a free state, the value of the distance r between the brush wire cutting end and the brush rod axis satisfies formula (a):

[0016] Compared with the traditional common brush descaling structure, the present invention has the following beneficial effects:

[0017] (1) The cutting width of the brush wire cutting end is small, which is conducive to cleaning the scale on the uneven surface, and each brush wire can independently extend and retract along the radial direction of the brush rod. No matter how many brush wires are involved in the cutting at the same time, and no matter whether the surface being cut is concave or convex, the dirt on the surface of the plate can be completely removed, so that the cathode plate resistance will not increase, the current efficiency will not decrease, and the water quality will not deteriorate during the operation of large and medium-sized electrochemical wastewater treatment reaction chambers.

[0018] (2) Compared with the lateral bending and profiling of the brush wires, the radial extension and profiling of the brush wires along the brush rod significantly reduces the squeezing effect of the front blade of the brush wire cutting end on the scale layer, improves the cutting performance of the brush wire cutting end, not only the descaling effect is cleaner and more thorough, but also reduces the energy consumption during the descaling process. The descaling brush body adopts a cylindrical shape, which rotates and moves while working. The cutting end forms a good peeling and cutting of the scale layer, with small cutting resistance and more significant energy saving effect.

[0019] (3) The descaling device described in the present invention can completely and thoroughly brush away the scale on the uneven surface of the cathode plate. Therefore, using the descaling device to clean the plates in the electrochemical reaction chamber can appropriately reduce the surface processing accuracy of the plates, thereby reducing the manufacturing cost of the plates, and achieving obvious economic benefits.

[0020] (4) Compared with the descaling brush with ordinary structure, the descaling brush body with telescopic brush wire has a smaller brush body diameter and a shorter extension length of the brush wire outside the descaling brush body. The center line of the descaling brush is close to the surface of the cathode cylinder, and the spacing distance between the cathode cylinder and the anode cylinder is reduced, which reduces the migration distance of ions in the water during electrolysis, reduces the volume of the reaction chamber, reduces the manufacturing cost of the reaction chamber, and improves the effective utilization rate of the electrolysis current.

[0021] (5) The theoretical results of the continuous cutting surface scheme have achieved the goal of not missing any cutting when multiple brushes are intermittently cutting. This provides a theoretical basis for the design and application of cylindrical brush telescopic contour cleaning brushes and promotes the development of electrochemical water treatment technology.

DETAILED DESCRIPTION

[0037] A brush wire telescopic descaling device for an electrochemical reaction chamber, as shown in the attached Figure 1 , Attachment Figure 6 , Attachment Figure 8 , Attachment Fig. 9 As shown, it includes a reaction chamber body; 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 outside the inner cathode cylinder 1, and a plurality of electrode cylinders coaxial with the inner cathode cylinder 1 and the outer cathode cylinder 2 are arranged between the inner cathode cylinder 1 and the outer cathode cylinder 2, and the electrode cylinder is composed of staggered cathode cylinders 3 and anode cylinders 4, and the anode cylinders 4 and the cathode cylinders 3, the inner cathode cylinder 1 and the outer cathode cylinder 2 are staggered;

[0038] As attached Figure 1 , Attachment Figure 6 , Attachment Figure 8 , Attachment Fig. 9 As shown, two cylindrical descaling brush bodies are arranged opposite to each other 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. A brush wire 5 which can be extended and retracted along the radial direction of the descaling brush body is slidably penetrated through the lower part of the circumferential surface of the descaling brush body.

[0039] In the present invention, each brush wire 5 can independently extend and retract along the radial direction of the brush rod, and the front cutting surface of the cutting end of the brush wire 5 has little extrusion effect on the scale layer, and the cutting energy consumption is low; multiple brush wires 5 can be cut simultaneously, not only the convex surface and the concave surface of the cathode plate can be effectively cut at the same time, but also the descaling efficiency is improved. The cutting width of the cutting end of the brush wire 5 is small, which is conducive to cleaning scale on uneven surfaces. At the same time, the cylindrical descaling brush body can realize self-rotation and movement, forming a good stripping and cutting of the scale layer, and the cutting resistance is small.

[0040] As attached Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Fig.10 , Attachment Fig.11 As shown, the descaling brush body includes a brush rod, and the brush rod includes a hollow cylindrical brush rod shell 6. A plurality of brush wire through holes 7 are opened at the lower part of the brush rod shell 6, and the brush wires 5 are passed through the brush wire through holes 7 one by one; the brush wires 5 include a plurality of brush wire groups distributed up and down, and the brush wires 5 of any two adjacent brush wire groups are arranged alternately along the circumference of the brush rod, and the upper and lower arrangement of the brush wire groups is a repeating unit with two brush wire groups; each brush wire group includes six evenly distributed brush wires 5, and the six brush wires in the same brush wire group are arranged in a staggered manner. The inner ends of the brush filaments 5 are connected correspondingly through three elastic bridge rods 8, which are in the shape of an arc that fits the inner wall of the brush rod shell 6 and are distributed in six rows; a brush core rod 9 is passed through the inner cavity of the brush rod shell 6, and six circumferentially distributed and vertically arranged convex ribs 10 are integrally provided on the lower side of the brush core rod 9; the six convex ribs 10 are in one-to-one contact with the middle of the six rows of elastic bridge rods 8; the top end of the brush core rod 9 is equipped with a limiting plate 11 whose lower surface is close to the upper surface of the brush rod shell 6 through a nut.

[0041] The brush filaments 5 are distributed into several brush filament groups, so that the brush filaments 5 are distributed in layers along the axial direction of the brush rod, and the brush filaments 5 of two adjacent layers are staggered; the number of brush filaments 5 in each brush filament group is equal, the brush filaments 5 in the same group are evenly distributed, and the two adjacent brush filaments 5 form a central angle α, as shown in the attached figure. Fig.10 As shown in the figure, α=60°, the angle between two adjacent brush through holes 7 in the axial projection of the brush filament 5 is δ1 or δ2, δ2=α-δ1, δ1=15°, δ2=45° in the figure; the corresponding central angle between two adjacent convex ribs 10 is equal to θ1 or θ2, θ1=α-δ1=45° or θ2=α+δ1=75°. At the same time, each brush filament can independently reciprocate along its own axis. Fig.13 shown.

[0042] The curvature of the elastic bridge rod 8 matches the inner side surface of the brush rod housing 6 , so that the brush rod housing 6 provides a certain support for the elastic bridge rod 8 .

[0043] When assembling the descaling brush body, first extend the cutting ends of all the brush filaments 5 out of the brush filament through hole 7 through the center hole of the brush rod shell 6 (the two brush filaments 5 have been connected to the elastic bridge rod 8 to form a U-shaped brush filament body before installation), and then press the convex rib 10 against the middle part of the corresponding elastic bridge rod 8, so that any brush filament 5 can be independently extended and retracted in the brush filament through hole 7 as needed.

[0044] When working, the axis of the descaling brush body is parallel to the surface of the cathode cylinder 3, the inner cathode cylinder 1 and the outer cathode cylinder 2 (hereinafter referred to as the cathode plate). The descaling brush body moves parallel to the surface of the cathode plate while rotating around its own axis. Fig.12 As shown; when the cutting end of a certain brush wire 5 moves to the uneven cathode plate to cut the scale layer, the brush wire 5, under the joint action of the elastic bridge rod 8 and the cathode plate surface, slides forward closely against the uneven cathode plate surface while telescoping along the brush wire through hole 7. When the brush wire 5 slides from low to high, the brush wire 5 overcomes the elastic force of the elastic bridge rod 8 under the action of the cathode plate surface and retracts into the descaling brush body. When the brush wire 5 slides from high to low, the brush wire 5 extends out of the descaling brush body under the elastic force of the elastic bridge rod 8. When the sliding distance of the cutting end of the brush wire 5 reaches its effective cutting length, it gradually leaves the cathode plate surface, and the cutting end of the next brush wire 5 cuts into the surface that has been cut by the previous brush wire 5 and continues to cut, forming a scale removal without missing. Since the telescopic movement of each brush wire 5 on the descaling brush body is independent, no matter how many brush wires act on the cathode plate surface at the same time, and no matter whether the brush wires 5 are cutting the low-lying surface or the convex surface of the cathode plate, the cutting end of each brush wire 5 can effectively press against the surface of the cathode plate for cutting.

[0045] As attached Figure 3 , Attachment Figure 4 As shown, the upper dimension of the brush rod shell 6 is smaller than its lower dimension, and the upper and lower parts of its inner wall are connected by a tapered guide surface; the bottom of the inner wall of the brush rod shell 6 is a tapered positioning surface; the upper part of the brush rod shell 6 is integrally provided with a guide boss 12 facing inward; the upper dimension of the brush core rod 9 is smaller than its lower dimension, and the upper and lower parts of its side are connected by a guide cone surface matching the shape of the tapered guide surface of the brush rod shell 6, the bottom of the side of the brush core rod 9 is a positioning cone surface matching the shape of the tapered positioning surface of the brush rod shell 6, and one side of the upper part of the side of the brush core rod 9 is a guide plane fitted with the guide boss 12; the bottom of the convex rib 10 is jointly provided with an annular water guide hole, and the bottom surface of the brush core rod 9 is provided with a plurality of drainage holes 13 connected to the water guide hole.

[0046] The combined structural design of the guide boss 12, the tapered guide surface, and the tapered positioning surface facilitates the positioning and guiding of the brush core rod 9 during assembly; the combined structural design of the water guide hole and the drain hole 13 facilitates the discharge of water entering the brush rod housing 6.

[0047] As attached Figure 5As shown, the side end of the brush wire 5 is provided with two oppositely arranged cutting grooves 14; the diameter of the elastic bridge rod 8 is smaller than the diameter of the brush wire 5;

[0048] The diameter of the elastic bridge rod 8 is smaller than the diameter of the brush wire 5 in order to prevent interference between two adjacent elastic bridge rods 8 during operation.

[0049] When the brush filament 5 is in a free state, the value of the distance r between the cutting end of the brush filament 5 and the brush rod axis satisfies formula (a):

[0050] r≥s+w (a)

[0051] Wherein, s is the distance from the cutting end of the brush wire 5 to the surface of the cathode cylinder 3, the inner cathode cylinder 1 or the outer cathode cylinder 2, in mm; w is the maximum fluctuation of the surface of the cathode cylinder 3, the inner cathode cylinder 1 or the outer cathode cylinder 2, in mm; the surface of the cathode cylinder 3, the inner cathode cylinder 1 or the outer cathode cylinder 2 is a surface without scale layer;

[0052] This parameter design ensures that the low-lying areas on the surface of the cathode tube 3, the inner cathode tube 1 or the outer cathode tube 2 are not missed. Fig.12 , Attachment Fig.14 As shown; From formula (a), we can see that s≤rw, that is, when s and w are constant, the larger r is, the longer the effective cutting length l of the brush wire cutting end is. 单 The longer; that is, when r and w are constant, the smaller s is, the effective cutting length l of the brush wire cutting end 单 The longer.

[0053] When the brush wires 5 are arranged, the spacing between two upper and lower adjacent brush wire groups is less than or equal to the effective cutting width h of a single brush wire 5 .

[0054] The structural design makes the brush wires 5 distributed in layers in the axial direction of the brush rod, two adjacent brush wire groups are staggered, and the layer spacing is less than or equal to the effective cutting width h of a single brush wire 5. Fig.11 As shown, the diameter of the brush wire 5 in the figure is 0.8 mm, h=0.6 mm, ensuring that no scale is missed between the effective cutting surfaces of two adjacent brush wire groups.

[0055] As attached Figure 1 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9As shown, a brush wire telescopic descaling device for an electrochemical reaction chamber also includes a descaling driving mechanism, which includes a spline shaft 15 arranged in the middle of the inner cavity of the inner cathode cylinder 1 and a spline sleeve 16 sleeved on the outside of the spline shaft 15, the spline sleeve 16 is rotatably supported on the top of the inner cathode cylinder 1 through a bearing seat 17, and a spline sleeve gear 18 located below the bearing seat 17 is fixedly assembled at the bottom of the spline sleeve 16, and a reduction motor 19 is arranged on the outside of the bearing seat 17 and fixedly connected with the base, the output shaft of the reduction motor 19 faces downward, and a reduction motor gear 20 meshing with the spline sleeve gear 18 is fixedly assembled on its output shaft; an inverted U-shaped descaling brush mounting frame 21 is fixedly sleeved on the top end of the spline shaft 15, a descaling brush rotating shaft rotatably passed through the descaling brush mounting frame 21 is fixedly connected to the top of the brush rod, and a descaling brush gear 22 is fixedly assembled on the top end of the descaling brush rotating shaft; the spline shaft 15 is transmission-connected to the descaling brush gear 22 through a transmission mechanism.

[0056] During operation, driven by the reduction motor 19, the reduction motor gear 20 drives the spline sleeve gear 18 and the spline sleeve 16 to rotate, and then drives the spline shaft 15 and the descaling brush mounting bracket 21 to rotate, thereby realizing the orbital motion of the descaling brush body around the axis of the reaction chamber body; at the same time, using the transmission mechanism, the spline shaft 15 rotates to drive the various descaling brush gears 22 to rotate, thereby realizing the self-rotation motion of the descaling brush body.

[0057] As attached Figure 8 , Attachment Fig. 9 As shown, the transmission mechanism includes a fixed inner gear ring 23 arranged at the top of the inner side wall of the inner cathode cylinder 1, a first transmission shaft 24 located inside the descaling brush rotating shaft is vertically rotated through one side of the descaling brush mounting bracket 21, a first transmission gear 25 located below the descaling brush mounting bracket 21 and meshing with the fixed inner gear ring 23 is fixedly mounted at the bottom end of the first transmission shaft 24; a second transmission gear 26 located above the descaling brush mounting bracket 21 is fixedly mounted at the top end of the first transmission shaft 24; a second transmission shaft 27 is rotatably penetrated at the top end of the spline shaft 15, and the second transmission gear 26 is meshed with the second transmission shaft 27. The lower part of the shaft 27 is fixedly equipped with a III transmission gear 28, and the III transmission gear 28 and the II transmission gear 26 are meshed with the II intermediate gear 30 through the I intermediate gear 29; the top of the II transmission shaft 27 is fixed with a plurality of connecting rods 31 evenly distributed along the circumference and located above the descaling brush gear 22, and the outer end of the connecting rod 31 is fixed with a rotating inner ring gear 32, which is respectively meshed with the two descaling brush gears 22 installed on the outer end of the descaling brush mounting frame 21, and the descaling brush gears 22 located on the same side are meshed in sequence from the outside to the inside.

[0058] During operation, the relative rotation between the spline shaft 15 and the fixed inner gear ring 23 drives the first transmission gear 25, the first transmission shaft 24, and the second transmission gear 26 to rotate, and then under the action of the first intermediate gear 29 and the second intermediate gear 30, the rotating inner gear ring 32 is driven to rotate. The rotation of the rotating inner gear ring 32 drives the two descaling brush gears 22 installed on the outer end of the descaling brush mounting frame 21 to rotate synchronously, and drives the remaining descaling brush gears 22 to rotate in sequence from the outside to the inside, thereby realizing the transmission process of the descaling brush body during its self-rotation motion.

[0059] As attached Fig.13 As shown, during the descaling operation, the values ​​of the rotation speed of the brush wire 5 and the sliding speed of the brush wire 5 on the surface of the cathode cylinder 3, the inner cathode cylinder 1 or the outer cathode cylinder 2 satisfy the formula (b):

[0060]

[0061] 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; v is the sliding speed of the brush wire 5 on the surface of the cathode cylinder 3, the inner cathode cylinder 1 or the outer cathode cylinder 2, which is the sum of the rotation linear speed and the revolution linear speed of the brush wire 5, and the unit is mm / s; α is the angle between two adjacent brush wires 5 in the same brush wire group, and the unit is degree; ξ is the minimum expansion and contraction amount of the brush wire 5 in the effective cutting stage, and the unit is mm;

[0062] This condition setting ensures that the effective cutting length of the brush filaments 5 of the same brush filament group is continuous without missing cutting.

[0063] When in use, in order to ensure that the cutting end of the brush wire 5 forms a good stripping and cutting of the scale layer, the linear speed direction of the cutting end of the brush wire 5 when cutting on the cathode plate surface is consistent with the sliding speed direction of the brush rod on the cathode plate surface.
