However, in this type of apparatus, in the process, the electric flocculation work and the floc cleaning work are performed in different apparatuses, respectively, that is, the sewage needs to be subjected to the electric flocculation work in the electric flocculation apparatus 1002 first, impurities are flocculated and separated from the water body, and then introduced into the slag scraping apparatus 1001, and the floc is removed from the water body by the slag scraping apparatus 1001, so that in the sewage treatment process, the integration degree of each process is low, and the sewage treatment efficiency is affected.
Disclosure of Invention
The invention aims to provide an electrochemical water treatment system of an electrolytic tank, which can continuously discharge floccules while performing electric flocculation work through a slag removal device, so that the integration degree of a sewage treatment process is improved, and the sewage treatment efficiency is further improved, and the problems in the background technology are solved.
In order to achieve the above purpose, the present invention provides the following technical solutions:
an electrolytic cell electrochemical water treatment system comprising:
the sewage treatment device comprises an electrolytic tank main body, wherein a water inlet pipe for introducing sewage is arranged at the lower right side of the electrolytic tank main body, a water outlet pipe for passing through treated sewage is arranged at the upper left side of the electrolytic tank main body, an electrolytic tank cover body is arranged at the top end of the electrolytic tank main body, two supporting shafts for communicating a power supply are arranged in the electrolytic tank cover body, a cathode rod and an anode rod are fixedly connected to the bottom ends of the supporting shafts respectively, a slag removing device is arranged in the electrolytic tank main body and the electrolytic tank cover body together, and floccules in the electrolytic tank main body are automatically and continuously discharged from the top end by the slag removing device when the sewage is introduced into the electrolytic tank main body.
As a preferable scheme of the invention, the slag removing device comprises a driving bin arranged in an electrolytic tank cover body, a driving motor is fixedly connected in the driving bin, a gear IV is fixedly connected to the output end of the driving motor, a sleeve II is sleeved on each supporting shaft, a gear I matched with the gear IV is arranged on the side wall surface of the sleeve II, a sleeve I is arranged at the bottom end of the sleeve II, the sleeve I is sleeved on the supporting shaft, two through holes I are arranged at the bottom end of the driving bin, the two through holes I are matched with the sleeve I, the sleeve I is sleeved on the supporting shaft, a supporting ring II is fixedly connected to the bottom end of the sleeve I, a slag removing plate is arranged at the bottom end of the sleeve I, the slag removing plate is enabled to extend below the sewage level, a guide cover is arranged in the electrolytic tank main body, a hole for installing the slag removing plate is formed in the guide cover, and two discharge ports are formed in the side wall surface of the electrolytic tank main body.
The first bottom of sleeve fixedly connected with support ring two, scarfing cinder board fixed connection is in support ring two bottom, support ring two all do not interfere each other with positive pole stick or cathode rod.
The three points that are worth explaining lie in, one, for the dismouting of make things convenient for inside spare part, can decompose the electrolysis trough lid into a plurality of spare parts, for example, make electrolysis trough lid top detachable apron, when the inside spare part of the electrolysis trough lid of needs dismouting, dismantle its apron, make the drive storehouse inside expose, but make things convenient for operating personnel to carry out the dismouting to the inside spare part of electrolysis trough lid at this moment, and after the dismouting work is accomplished, connect its apron again at electrolysis trough lid top through modes such as bolt. The connection relation between the output end of the driving motor and the gears III and IV can be realized by connecting an output shaft on the output end of the driving motor in a coupling mode and welding the gears III and IV on the output shaft. Thirdly, the connection mode between the electrolytic tank cover body and the electrolytic tank main body can adopt a mode that a plurality of metal locks are matched for use, at the moment, the disassembly and assembly between the electrolytic tank cover body and the electrolytic tank main body are facilitated, the equipment is convenient to overhaul and the replacement of parts by workers, but the method has poor resistance to the mechanical vibration of the equipment, and is suitable for small-sized equipment with small mechanical vibration and high electrode replacement frequency; in addition, the mode of bolt connection can also be adopted, at the moment, the connection between the electrolytic tank cover body and the electrolytic tank main body is firmer, the electrolytic tank cover body is not easy to loosen due to vibration, but correspondingly, the method is inconvenient to disassemble and assemble, and is further inconvenient for equipment maintenance and part replacement, so that the connection mode is more suitable for large-scale equipment with larger mechanical vibration and low electrode replacement frequency.
Based on the design of this scheme, through the cooperation relation of a plurality of gears one and gear four, can transmit the rotary motion of driving motor output to a plurality of sleeves two, sleeve two is rotatory through a sleeve belt drive clear slag plate again, clear slag plate is at rotatory in-process, send the floc that suspends in sewage to the liquid level of sewage, promote the separation of floc and water, simultaneously, still will float the floc on the sewage liquid level, through seting up the hole on the direction lid, send into in the direction lid to under the direction effect of direction lid, discharge the inside electrolysis trough main part through the bin outlet, realize the automatic continuous discharge of floc.
The two points which are needed to be specially supplemented are that one of the two points is that the floccules can be discharged out of the electrolytic tank main body along the guide cover and the discharge hole, because when the floccules are fed into the guide cover by the slag removing plate, a small part of sewage is simultaneously fed into the guide cover according to the different rotating speeds of the slag removing plate, and at the moment, the floccules are in a wet and soft state and are easy to be pushed by water flow, so that the floccules can be continuously discharged out of the discharge hole under the flushing of a small part of sewage. Secondly, in order to ensure the guiding effect of the guiding cover on the floccule, the floccule can be accurately discharged from the discharge hole, and the slope design matched with the discharge hole can be carried out on the inner wall of the guide cover so that the floccule can be guided to the inlet of the discharge hole along the designed slope, and then the floccule is discharged out of the main body of the electrolytic tank.
In addition, the discharge opening should be inclined downward, i.e. the outlet height of the discharge opening is lower than the inlet height, thereby ensuring that the flocs in the guiding cover can smoothly flow out along the discharge opening.
Furthermore, through setting up support ring two, can be under the circumstances that does not increase sleeve two whole volumes, make the slag removal board obtain bigger, more agree with the installation area of self shape, be favorable to the installation of slag removal board. In addition, because the floccule is sent into the guide cover in a moist and soft state, the floccule is easy to invade into a fit clearance between the first through hole and the first sleeve, so that the fit clearance is worn, and the first through hole and the first sleeve are in poor fit, so that the mechanical vibration of equipment is increased, the equipment is not beneficial to work, the second supporting ring plays a shielding role on the fit clearance between the corresponding first through hole and the first sleeve, and the floccule can be prevented from invading into the fit clearance after being sent into the guide cover by the slag removing plate, so that the fit relation between the first through hole and the first sleeve is protected.
As a preferable mode of the invention, the two through holes I are uniformly and symmetrically arranged, and the driving motor is positioned between the two through holes I.
Based on the design of this scheme, can make a plurality of clear slag plates also be even symmetry and arrange, simultaneously, because clear slag plate stretches into under the sewage liquid level, consequently the motion of clear slag plate will produce stirring effect to sewage, and then improve sewage treatment's flocculation efficiency, again because driving motor is located between two through-holes, consequently under driving motor's effect, a plurality of clear slag plates will produce the rotation that the opposite direction, make the sewage mutual collision between a plurality of clear slag plates form the torrent, and then the suppression sewage is because taking rotatory stirring, and the formation of the swirl that leads to has guaranteed the stirring effect.
In contrast, if the two through holes are formed in a way that the two through holes are not uniformly and symmetrically arranged, namely, the arrangement way of the two slag removal plates is not uniformly and symmetrically arranged, the two slag removal plates are integrally biased to one side in the electrolytic tank main body, and the stirring effect of the two slag removal plates in the electrolytic tank main body is uneven, so that the flocculation effect is affected.
In addition, it is worth to be particularly stated that, because the slag removal plate realizes the stirring function and the function of cleaning floccules simultaneously, the process integration degree of the electric flocculation water treatment is improved, namely, the equipment can be used for improving the flocculation efficiency by continuously stirring the slag removal plate on one hand and continuously discharging floccules on the other hand simultaneously, thereby improving the integration degree of the sewage treatment process and further improving the sewage treatment efficiency while carrying out the electric flocculation work.
As a preferable scheme of the invention, the slag removing plate is provided with a second through hole, the second through hole is matched with the cathode rod or the anode rod, and the second through hole is matched with the supporting shaft.
The slag removing plate is a spiral plate, and the second through hole is formed at the spiral central shaft of the slag removing plate
Based on this design, can make the scarfing cinder board cover establish on cathode bar or positive pole stick, save the space that the scarfing cinder board occupy, simultaneously, can also restrict the position of scarfing cinder board when scarfing cinder board works, prevent scarfing cinder board break away from working position, and then lead to stirring effect reduction or other spare parts of equipment impaired.
Further, because the slag removing plate is a spiral plate, when the slag removing plate is sleeved on the anode or the cathode, the slag removing plate can push sewage downwards or upwards according to the principle similar to a spiral feeder in the rotating process, and in the pushing process, the sewage has mutual resistance, so that the sewage can be dispersed in a part of horizontal direction in the pushing process downwards or upwards, the flowing of the sewage in the main body of the electrolytic tank is further enhanced, namely the stirring effect of the slag removing plate on the sewage is enhanced, the flocculation efficiency is improved, the sewage treatment efficiency is improved, meanwhile, the slag removing plate is in a spiral shape and is sleeved on the electrode through a through hole II, the slag removing plate is not easy to deform radially in the stirring process, and the stirring effect is ensured. In addition, it is worth to say that when the spiral plate is adopted as the slag removing plate, in order to ensure the spiral conveying effect, the slag removing plate is required to obtain a rough surface by means of processing and the like, or a baffle is arranged on the outer edge of the slag removing plate so as to prevent floccules from being thrown away from the slag removing plate due to the action of centrifugal force in the spiral conveying process, and the conveying effect is ensured.
On the other hand, if the plate-shaped slag removing plate is adopted, on one hand, the stirring direction generated by the plate-shaped slag removing plate is single, only stirring in the horizontal direction can be generated, and the stirring effect is limited; on the other hand, when stirring sewage, the plate-shaped slag removing plate is easy to bend and deform, so that the stirring effect and the service life of the slag removing plate are affected, and even if components are added on the plate-shaped slag removing plate or the thickness of the slag removing plate is simply increased in order to enhance the bending resistance of the plate-shaped slag removing plate, the mass of the slag removing plate is increased, so that the driving motor needs to provide larger torque, and the electricity cost is increased.
As a preferable scheme of the invention, the bottom end of each slag removing plate is fixedly connected with a first supporting ring, the length of the slag removing plate sleeved on the anode rod is longer than that of the slag removing plate sleeved on the cathode rod, the corresponding first supporting ring can be arranged at the bottom of the main body of the electrolytic tank, the bottom of the main body of the electrolytic tank is symmetrically and fixedly provided with a limiting round platform, the limiting round platform is matched with the first supporting ring, the two limiting round platforms are respectively positioned below the anode rod and the cathode rod, and each limiting round platform is not interfered with the slag removing plate.
The electrolytic tank is characterized in that a plurality of supporting rods are fixedly connected to the bottom end of the main body of the electrolytic tank, the supporting rods are mutually matched with a supporting ring close to one side of the water inlet pipe, and the top end of each supporting rod is higher than the upper side wall surface of the water inlet pipe
As a preferable scheme of the invention, the first supporting ring corresponding to the slag removing plate sleeved on the anode rod is slidably arranged at the bottom of the main body of the electrolytic tank, and the specific installation mode is that the first supporting ring corresponding to the slag removing plate sleeved on the anode rod is sleeved on the limiting round table.
In contrast, the installation mode can also adopt a bearing connection mode, at the moment, the rotation effect of the first supporting ring relative to the limiting round table can be guaranteed, but the requirement on the selected bearing is high, different bearings are needed to be selected according to the acid-base property, the corrosiveness and other properties of sewage, and the equipment cost is increased.
Based on the design scheme, when the driving motor rotates positively, the slag removing plate sleeved on the anode rod pushes sewage from bottom to top, the sewage entering the electrolytic tank main body from the water inlet pipe can directly flow to the upper surface of the supporting ring, namely, the sewage can directly flow to the slag removing plate sleeved on the anode rod, so that the sewage which just enters the electrolytic tank main body and has higher impurity content can directly and quickly participate in the stirring process, thereby being beneficial to improving flocculation efficiency; when the driving motor rotates reversely, the slag removing plate sleeved on the anode rod pushes sewage from top to bottom, the sewage is flushed to the bottom of the electrolytic tank main body, and the flowing direction is changed, wherein the flowing direction of one part of the sewage is opposite to the flowing direction of the sewage entering the electrolytic tank main body from the water inlet pipe, so that the blocking effect is generated on the sewage entering the electrolytic tank main body from the water inlet pipe, the flow rate of the sewage entering the electrolytic tank main body from the water inlet pipe is slowed down, the impact on the water body in the electrolytic tank main body due to the flow rate change of the sewage entering from the water inlet pipe is reduced, the water body in the electrolytic tank main body can be in a stable state, and the equipment can work under a stable working condition.
Further, through setting up a plurality of bracing pieces for the cover is established the scarfing cinder board on the cathode bar, and the height of its bottom is higher than the height of inlet tube upper side wall face all the time, has reduced the sewage of leading in from the inlet tube, to the impact of the scarfing cinder board of cover on the cathode bar, reduces this scarfing cinder board because receive fluid to wash out the wearing and tearing that lead to, improves the life of scarfing cinder board, reduction equipment cost.
On the other hand, when the slag removing plate sleeved on the anode rod pushes the sewage from bottom to top, the sewage entering the electrolytic tank main body from the water inlet pipe can be flushed onto the slag removing plate sleeved on the anode rod without being blocked by the slag removing plate sleeved on the cathode rod, so that the sewage with higher impurity content can be rapidly involved in the stirring process; on the other hand, when the slag removing plate sleeved on the anode rod pushes the sewage from top to bottom, the buffer effect of the sewage in the electrolytic tank body on the sewage introduced from the water inlet pipe is not hindered, and the buffer effect is ensured.
As a preferable scheme of the invention, the bottom end of the sleeve II is fixedly connected with a plurality of bosses, the top end of the sleeve I is provided with a plurality of grooves matched with the bosses, the sleeve I is sleeved with a spring, the top end of the spring is fixedly connected with a clamping ring, the other end of the spring is fixedly connected with the bottom end of the driving bin, and the clamping ring is sleeved on the sleeve I.
The gear I is fixedly connected with a gear II, the gear II is positioned above the gear I, the output end of the driving motor is fixedly connected with a gear III, the gear III is positioned above a gear IV, the gear III and the gear II are matched with each other, the bottom end of the driving bin is fixedly connected with a plurality of electric telescopic rods, the extending end of each electric telescopic rod is fixedly connected with a shifting fork, the shifting fork is matched with the sleeve II, the drive bin bottom fixedly connected with a plurality of proximity switches, every proximity switch all mutually supports with the snap ring, and a plurality of proximity switches respectively with a plurality of electric telescopic handle electric connection, every on the sleeve two all around being equipped with reset spring, reset spring top and drive bin top fixed connection, reset spring is in compression state all the time, and reset spring bottom and gear two contact.
The first gear is connected to the second sleeve in a key connection mode, so that the first gear can smoothly transmit torque and can slide up and down on the second sleeve
When the driving motor works, when the fit clearance between the anode rod or the cathode rod and the corresponding slag removing plate is not blocked by impurities or floccules, or the fit clearance between the first through hole and the corresponding first sleeve is not blocked by oxides generated by corrosion, the boss is matched with the groove under the action of the elasticity of the spring, and the boss cannot be separated from the groove under the action of the pressing force of the spring at the moment, so that the first sleeve can be driven to rotate by the second sleeve; otherwise, the torque required by the rotation of the slag removing plate is increased, the boss overcomes the pressing force of the spring and is separated from the inside of the groove, and in the subsequent process, as long as the fit clearance between the anode rod or the cathode rod and the corresponding slag removing plate is still blocked by floccules, the sleeve II can not drive the sleeve I to rotate, so that the damage of the cathode rod, the slag removing plate or other parts in the equipment is prevented.
Further, when the fit gap between the anode rod or the cathode rod and the corresponding slag removing plate is blocked by floccules, or the fit gap between the first through hole and the first corresponding sleeve is blocked by oxides generated by corrosion, the boss is separated from the inside of the groove, the spring is compressed, the clamping ring moves vertically downwards to trigger the corresponding proximity switch to enable the corresponding electric telescopic rod to extend, the corresponding shifting fork shifts the corresponding gear I and the corresponding gear II upwards at the moment, the gear II is matched with the gear three phases, the rotating speed of the corresponding slag removing plate is slowed down, the first sleeve and the second sleeve rotate relatively at the moment, the boss and the groove are matched intermittently, at the moment, the slag removing plate rotates at a low speed and simultaneously vibrates periodically up and down, oxides, floccules or impurities which have an obstacle effect on the operation of equipment can be gradually shaken out, and the equipment is restored to a normal working state.
The invention has the main beneficial effects that:
1. when the driving motor drives the slag removing plate to rotate, flocs suspended in the sewage are sent to the liquid level of the sewage, separation of the flocs and a water body is promoted, and the flocs floating on the liquid level of the sewage are continuously discharged out of the electrolytic tank main body;
2. further, the motion of the slag removing plates has a stirring effect on sewage, so that the flocculation efficiency of sewage treatment is improved, and the slag removing plates rotate in opposite directions, so that the sewage among the slag removing plates collides with each other to form turbulence, thereby inhibiting vortex generation caused by adopting rotary stirring of the sewage, and ensuring the stirring effect;
3. furthermore, when the driving motor rotates positively, the slag removing plate sleeved on the anode rod pushes the sewage from bottom to top, so that the sewage with higher impurity content just entering the main body of the electrolytic tank can directly and rapidly participate in the stirring process, thereby being beneficial to improving flocculation efficiency;
