s1: water treatment: opening a water inlet electromagnetic valve and a water outlet electromagnetic valve, and switching on an electrolytic power supply to perform water treatment;

s2: the descaling mechanism moves downwards: when the water treatment reaches the specified time, firstly, the microcontroller generates a control instruction to cut off an electrolytic power supply, then the microcontroller controls a water inlet electromagnetic valve and a water outlet electromagnetic valve to be closed, then the microcontroller controls a reduction motor to rotate forwards, the spline sleeve is driven to rotate under the transmission of a reduction motor gear and a spline sleeve gear, and further the spline shaft is driven to rotate;

s3: descaling: when the speed reducing motor runs for a specified time, the descaling brush body descends to a fixed inner gear ring to be meshed with the transmission gear I, the microcontroller controls the speed reducing motor to stop, and controls the screw rod brake mechanism to release the screw rod at the same time, then the microcontroller controls the speed reducing motor to continue to rotate forwards, and the screw rod rotates synchronously with the spline shaft, so that the spline shaft rotates directionally at a specified position to drive the descaling brush body to revolve; the first transmission gear is meshed with the fixed inner gear ring, the revolution of the descaling brush body drives the first transmission shaft and the second transmission gear to rotate, and under the transmission of the first intermediate gear and the second intermediate gear, the third transmission gear, the second transmission shaft and the rotating inner gear ring are driven to rotate, so that the two descaling brush gears arranged at the outer end of the descaling brush mounting frame are driven to rotate, other descaling brush gears are driven to rotate in sequence, and each descaling brush body is driven to rotate to realize a descaling function;

s4: the descaling mechanism goes up: when the step S3 is run for a specified time, the microcontroller controls the speed reducing motor to stop, and simultaneously controls the scale removing electromagnetic valve to be opened, then the microcontroller controls the screw rod braking mechanism to brake the screw rod, then the microcontroller controls the speed reducing motor to rotate reversely, under the transmission of the gear of the speed reducing motor and the gear of the spline sleeve, the spline sleeve is driven to rotate, and further the spline shaft is driven to rotate, meanwhile, the screw rod is still under the action of the screw rod braking mechanism, so that the spline shaft drives the scale removing brush body to rotate while going upwards, and the scale removing mechanism goes upwards;

Compared with the existing electrochemical reaction chamber, the automatic electrochemical reaction chamber and the control method thereof have the following beneficial effects:

(1) compared with a descaling brush with a common structure, the brush wire telescopic descaling brush body has the advantages that the diameter of the descaling brush body is reduced, the extending length of the brush wire outside the descaling brush body is shortened, the center line of the descaling brush body is close to the surface of the cathode cylinder, the spacing distance between the cathode cylinder and the anode cylinder is reduced, the migration distance of ions in a water body during electrolysis is reduced, the volume of a reaction chamber body is reduced, the manufacturing cost of the reaction chamber is reduced, and the effective utilization rate of electrolytic current is improved.

(2) Because electrochemistry sewage treatment reaction chamber, the diameter of a cathode cylinder is big, and is highly high, and cathode cylinder surface unevenness is general bigger, and the back is scraped to the scraper now, remains the dirt layer and all is more than 80% at the percentage of coverage on cathode surface, along with scraping the increase of number of times, remains dirt layer density bigger and bigger, and electrolytic resistance is bigger and bigger, and product water quality is more and more poor. When the descaling brush with the common structure is used for descaling, the cathode surface fluctuation condition is adapted by the transverse bending deformation of the brush wire, the brushing and cutting resistance is large, the effective brushing and cutting area is small, and the brushing and cutting stripping effect is seriously influenced by the rolling of the brush wire on a scale layer after the brush wire is transversely bent. The invention adopts the brush wire telescopic descaling brush body for brushing, reduces brushing resistance, increases effective brushing area, improves stripping effect of brush wire brushing, and greatly improves cleaning rate of dirt, thereby improving effective utilization rate of current and water quality.

(3) The larger the spacing distance between the cathode cylinder and the anode cylinder is, the longer the migration path of ions in the overflowing water body is, and the higher the height of the reaction chamber is, so that the reaction chamber is large in size and large in working power consumption. The invention adopts the brush wire telescopic descaling brush, reduces the spacing distance between the cathode cylinder and the anode cylinder, not only effectively reduces the electric energy consumption, but also reduces the volume of the reaction chamber body, and reduces the manufacturing difficulty and the manufacturing cost of the reaction chamber.

(4) The larger the spacing distance between the cathode cylinder and the anode cylinder is, the more uneven the electromagnetic field distribution between the cathode cylinder and the anode cylinder is, the invention adopts the brush wire telescopic descaling brush body, reduces the spacing distance between the cathode cylinder and the anode cylinder, and effectively improves the electromagnetic field distribution uniformity of the reaction chamber, thereby improving the water quality of the produced water.

(5) Under the condition that the distance between the cathode cylinder and the anode cylinder is the same, the larger the curvature of the cathode cylinder and the anode cylinder is, the more uneven the electromagnetic field distribution between the cathode cylinder and the anode cylinder is, the invention cancels the small-diameter cathode cylinder and the anode cylinder in the central area of the reaction chamber, and the central area is provided with the descaling brush lifting revolution system and the automatic transmission system, and is provided with the natural air cooling system, thereby not only effectively improving the electromagnetic field distribution uniformity of the reaction chamber, ensuring the uniformity of the water quality of the water produced by the reaction chamber in the electromagnetic field distribution, but also fully utilizing the effective space in the central area.

(6) Because the outer bottom shell and the inner bottom shell in the reaction chamber are all spherical shells, the water inlet is positioned at the bottom of the outer bottom shell and is coaxial with the reaction chamber, and the top of the reaction chamber adopts a full-circle overflow mode, so that the flow velocity of water flow rising everywhere in the reaction chamber is equal, and the uniformity of the quality of water produced by the reaction chamber is ensured on the flow velocity of water.

(7) As the peripheral air is heated and rises in the process that the water body falls to the annular water collecting tank from the overflow lip plate, a strong convection air cooling state is formed, and the water body is continuously cooled. Meanwhile, the air in the hollow barrel in the reaction chamber is heated and ascended by the inner barrel wall with higher temperature, the cold air enters and is supplemented by the air channel at the bottom of the barrel to form a strong convection air cooling state, and the room temperature of the reaction chamber is correspondingly inhibited

(8) The hollow supporting tube structure of the reaction chamber is not only an installation base of the cathode cylinder and the anode cylinder, but also an air cooling air duct of the hollow cathode cylinder, and is also a wiring base of the cable channel and the anode cylinder for the cathode cylinder, the anode cylinder, the speed reducing motor and the like. The multifunctional combined shoe has multiple functions, simple and compact structure and low manufacturing cost.

(9) In conclusion, the automatic electrochemical reaction chamber not only can improve the cleaning rate of the scale layer, but also can improve the distribution uniformity of an electromagnetic field and the flow velocity uniformity of water passing. Under the condition of equal flow, the water quality of the produced water can be improved; the power consumption and the electric energy in daily operation of the equipment can be reduced; the water temperature of the produced water can be reduced, and the cooling effect of the produced water is improved; the height of the reaction chamber can be reduced, and the manufacturing cost of the equipment can be reduced.

The cutting width of the cutting end of the brush wire 5 is small, which is beneficial to cleaning dirt on uneven surfaces. Meanwhile, the cylindrical descaling brush body can move while rotating, good stripping and cutting are formed on a scale layer, and the cutting resistance is small.

As shown in fig. 7-11, the descaling brush body comprises a descaling brush rotating shaft rotatably penetrating through the descaling brush mounting frame 14 and a brush rod fixedly connected to the bottom of the descaling brush rotating shaft, and a descaling brush gear 15 is fixedly assembled at the top end of the descaling brush rotating shaft; the brush rod comprises a hollow cylindrical brush rod shell 45, a plurality of brush wire through holes 46 are formed in the lower portion of the brush rod shell 45, and the brush wires 5 penetrate through the brush wire through holes 46 in a one-to-one correspondence mode; the brush wires 5 comprise a plurality of brush wire groups which are distributed up and down, the brush wires 5 of any two adjacent brush wire groups are staggered along the circumferential direction of the brush rod, and the two brush wire groups are arranged up and down to form a repeating unit; each brush wire group comprises six brush wires 5 which are uniformly distributed, the inner end parts of the six brush wires 5 positioned in the same brush wire group are correspondingly connected through three elastic bridge rods 47, and the elastic bridge rods 47 are in an arc shape which is attached to the inner side wall of the brush rod shell 45 and are distributed in six rows; a brush core rod 48 penetrates through the inner cavity of the brush core rod shell 45, and six rib strips 49 which are circumferentially distributed and vertically arranged are integrally arranged at the lower part of the side surface of the brush core rod 48; six convex ribs 49 are correspondingly abutted against the middle parts of the six rows of elastic bridge rods 47 one by one; a stopper plate 50 having a lower surface closely contacting the upper surface of the brush rod case 45 is attached to the tip end portion of the brush rod 48 via a nut.

The brush wires 5 are distributed into a plurality of brush wire groups, so that the brush wires 5 are distributed in layers along the axial direction of the brush rod, and the adjacent two layers of brush wires 5 are distributed in a staggered manner; the number of the brush filaments 5 in each brush filament group is equal, the brush filaments 5 in the same group are uniformly distributed, and two adjacent brush filaments 5 form a central angle α, as shown in fig. 11, where α is 60 °, and an included angle between two adjacent brush filament through holes 46 in axial projection of the brush filaments 5 is δ₁Or delta₂，δ₂＝α-δ₁Delta in the figure₁＝15°，δ₂45 degrees; the corresponding central angle between two adjacent convex ribs 49 is equal to theta₁Or theta₂，θ₁＝α-δ ₁45 ° or θ₂＝α+δ₁75 deg.. And each brush wire 5 can independently reciprocate in the direction of the axis thereof to move linearly, as shown in fig. 14.

The curvature of the elastic bridge rod 47 is matched with the inner side surface of the brush rod shell 45, so that the brush rod shell 45 provides a certain supporting function for the elastic bridge rod 47.

When assembling the descaling brush body, the cutting ends of all the brush wires 5 extend out of the brush wire through holes 46 through the center holes of the brush rod shell 45 (the two brush wires 5 are connected with the elastic bridge rod 47 to form a U-shaped brush wire body before installation), and then the rib strips 49 are pressed against the middle parts of the corresponding elastic bridge rods 47, so that any brush wire 5 can independently stretch in the brush wire through holes 46 as required.

When the descaling brush works, the axis of the descaling brush body is parallel to the surfaces of the cathode cylinder 3, the inner cathode cylinder 1 and the outer cathode cylinder 2 (hereinafter referred to as cathode plate), and the descaling brush body does autorotation motion around the axis of the descaling brush body while moving in parallel along the surface of the cathode plate, as shown in figure 13; when the cutting end of a certain brush wire 5 moves to the uneven cathode plate to cut scale layers, the brush wire 5 slides forwards along the uneven surface of the cathode plate while clinging to the uneven surface of the cathode plate and moves telescopically along the brush wire through hole 46 under the combined action of the elastic bridge rod 47 and the surface of the cathode plate. When the brush wires 5 slide from low to high, the brush wires 5 are retracted into the descaling brush body under the action of the surface of the cathode plate and against the elasticity of the elastic bridge rod 47. 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 47. When the sliding path of the cutting end of the brush wire 5 reaches the effective cutting length, the brush wire gradually leaves the surface of the cathode plate, and the cutting end of the next brush wire 5 is cut into the surface cut by the previous brush wire 5 and then cut, so that the non-skimming descaling is formed. Because the telescopic motion of each brush wire 5 on the descaling brush body is independent, the cutting end of each brush wire 5 can be effectively pressed against the surface of the cathode plate to cut no matter how many brush wires are simultaneously acted on the surface of the cathode plate, and no matter whether the brush wires 5 cut on the low-lying surface or the convex surface of the cathode plate.

the diameter of the elastic bridging rod 47 is smaller than that of the brush filaments 5 so as to prevent the adjacent two elastic bridging rods 47 from interfering during operation.
