Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 2 to 3, a water treatment apparatus for recovering metal from industrial wastewater by using magnetic force includes a treatment tank 1, a main driving device, and an adsorption roller 2; an electromagnet is arranged in the adsorption roller 2, and the adsorption roller 2 can rotate; the inner wall of the treatment pool 1 is fixedly provided with a main driving device which can drive the adsorption roller 2 to rotate in the treatment pool 1.
The main driving device comprises a fixed shaft 3, a sun gear 4 is fixedly arranged on the outer wall of the fixed shaft 3, a planet gear 5 is meshed with the sun gear 4, a gear ring 6 is meshed with the outer side of the planet gear 5, and an adsorption roller 2 is fixedly arranged on the side wall of the planet gear 5.
When the device works, industrial wastewater to be treated needs to be poured into the treatment pool 1, then the electromagnet in the adsorption roller 2 is started to adsorb magnetic metal in the wastewater, and meanwhile, the adsorption roller 2 can revolve around the fixed shaft 3 by driving the gear ring 6 to rotate, wherein the principle of the planet wheel is used, so that the wastewater in the treatment pool 1 is stirred, and the adsorption roller 2 is fully contacted with the wastewater, so that the magnetic metal in the wastewater can be fully adsorbed.
Through planetary gear's principle, rotate through drive ring gear 6, can be so that adsorption roller 2 also can produce the rotation by oneself when carrying out the revolution around fixed axle 3, under the prerequisite that magnetic force adsorbs magnetic metal, the centrifugal force of recycling the rotation production of adsorption roller 2 comes to throw away the great magnetic metal of volume, and then accomplishes the separation of great magnetic metal and less magnetic metal. Because the filter screen is not used in the whole process, the situation that the filter screen needs to be cleaned always can not occur, and the magnetic metals with different sizes can be directly separated from the industrial wastewater, so that the recovery of the magnetic metals is more efficient than that of the existing industrial wastewater.
Here, it is necessary to specifically explain the principle that the larger magnetic metal is thrown out, as shown in fig. 16, the largest circle represents the attraction roller 2, the left circle below the attraction roller 2 represents the larger magnetic metal, and the right circle represents the smaller magnetic metal. The critical value that the magnetic metal is not thrown away by the rotation of the adsorption roller 2 is that the magnetic force of the electromagnet can just provide the centripetal force that the magnetic metal rotates around the axis of the adsorption roller 2. It can be seen that the larger magnetic metal mass center is far away from the rotation center of the adsorption roller 2, and R1 is greater than R2, and since the smaller magnetic metal and the larger magnetic metal rotate at the same angular velocity, the larger magnetic metal reaches the critical value first according to the formula of centripetal acceleration of circular motion. It is possible to throw a larger amount of magnetic metal off the attraction roller 2 by increasing the rotation speed of the attraction roller 2. Through the autorotation multi-stage speed regulation of the adsorption roller 2, the magnetic metal separation in a multi-stage size range can be realized. Therefore, the invention can realize the separation of the larger magnetic metal and the smaller magnetic metal.
Referring to fig. 4 to 6, as a further aspect of the present invention, a first magnetic metal collecting device is further installed on the inner wall of the processing tank 1; the first magnetic metal collecting device comprises a collecting box 7, a collecting plate 8 and a mandril 9; one end of the collecting plate 8 is hinged to the inner wall of the treatment tank 1, the other end of the collecting plate 8 is positioned on the advancing path of the adsorption roller 2, one end of the collecting plate 8, which is positioned on the advancing path of the adsorption roller 2, is provided with a scraping head 10, an electromagnet is installed in the scraping head 10, and the collecting plate 8 can stretch out and draw back; the ejector rod 9 is connected with the inner wall of the treatment pool 1 through a linear elastic element, the ejector rod 9 is supported below the collecting plate 8, and the ejector rod 9 is positioned on the advancing route of the adsorption roller 2; the collecting box 7 is located below the collecting plate 8.
When the invention works, although the separation of larger magnetic metal and smaller magnetic metal is realized by the magnetism of the adsorption roller 2 and the centrifugal force of autorotation, the collection of smaller magnetic metal is not convenient enough, and the problem can be solved by the structure. As shown in fig. 4, in the present embodiment, the power source (which may be a motor driving a gear or driven by a belt) drives the ring gear 6 to rotate counterclockwise, and as can be seen from the principle of the planetary gear train, the planet gear 5 will revolve counterclockwise around the sun gear 4 and will rotate in the counterclockwise direction. The adsorption roller 2 is rotated counterclockwise to be close to the squeegee head 10 upward after entering the treatment tank 1 to adsorb the magnetic metal. Since the electromagnet is also installed in the scraping head 10, and the power of the electromagnet is larger than that of the electromagnet in the adsorption roller 2, when the scraping head 10 and the adsorption roller 2 are in line contact, the magnetic metal on the contact line of the adsorption roller 2 and the scraping head 10 is adsorbed. Since the attraction roller 2 itself also rotates counterclockwise, the magnetic metal attracted by one turn is guided to the squeegee head 10. Preferably, the electromagnet of the adsorption roller 2 can be turned off when the adsorption roller 2 rotates to a position where all the magnetic metal is located in the upper half of the adsorption roller 2, so that the magnetic metal is better adsorbed by the scraper head 10. Since the collecting plate 8 can be extended and contracted, it does not interfere with the movement of the suction roller 2.
After the head 10 finishes adsorbing the magnetic metal on the adsorption roller 2, the adsorption roller 2 moves to the lower part of the head 10 at the moment, the electromagnet in the head 10 is closed at the moment, a part of magnetic metal can slide to the collection box 7 along the collection plate 8, meanwhile, the adsorption roller 2 can be contacted with the ejector rod 9 due to continuous rotation, the ejector rod 9 can be extruded along with the movement of the adsorption roller 2, the ejector rod 9 is connected with the inner wall of the treatment pool through an air spring, the ejector rod 9 can move to one side, the collection plate 8 can be upwards jacked up at the top of the ejector rod 9, the collection plate 8 can rotate around the hinge point of the collection plate and the treatment pool 1, the inclination of the collection plate 8 can be increased, more magnetic metals on the collection plate 8 can slide to the collection box 7, and collection of the magnetic metals on the adsorption roller 2 can be conveniently completed.
Referring to fig. 7, as a further aspect of the present invention, the collecting plate 8 includes an inner plate 11 and an outer plate 12, the outer plate 12 is slidably sleeved on the outer side of the inner plate 11, the inner plate 11 is elastically connected to the outer plate 12, one end of the inner plate 11 is fixedly connected to the inner wall of the treating tank 1, and the scraping head 10 is disposed on the outer plate 12.
Because the extension and contraction of the collecting plate 8 are realized by sleeving the outer plate 12 on the outer side of the inner plate 11, the upper edge of the outer plate 12 is higher than the inner plate 11, so that the magnetic metal on the scraper head 10 can be prevented from being clamped on the collecting plate 8 when sliding down along the collecting plate 8.
Referring to fig. 8, as a further embodiment of the present invention, the bottom of the treatment tank 1 is provided with an agitation plate 13 and a reciprocating mechanism; the stirring plate 13 is vertically arranged; the reciprocating mechanism is used for driving the stirring plate 13 to reciprocate at the bottom of the treatment tank 1.
The reciprocating motion mechanism drives the stirring plate 13 to do reciprocating motion at the bottom of the treatment pool 1, so that the magnetic metal in the wastewater can be prevented from precipitating at the bottom, and the magnetic metal in the treatment pool 1 can be better adsorbed and separated.
Referring to fig. 8 to 12, as a further aspect of the present invention, the reciprocating mechanism includes a screw rod 15, a moving table 16 is screwed on an outer wall of the screw rod 15, the moving table 16 is slidably connected to an inner wall of the treatment tank 1, and a connecting rod 17 is fixedly disposed at a bottom of the moving table 16; the stirring plate 13 is arranged at the bottom of the connecting rod 17, and the stirring plate 13 can be driven by a reciprocating mechanism to turn over when moving to two sides of the treatment tank 1; collecting grooves 18 are formed in two sides of the bottom of the treatment pool 1, a collecting port 19 is formed in one end of each collecting groove 18, and a sealing block 20 is inserted into each collecting port 19.
When the device works, after magnetic metal in the treatment tank 1 is fully adsorbed and collected, the residual large magnetic metal also needs to be collected, because the outer wall of the screw rod 15 is matched with the moving platform 16 in a threaded manner, and the moving platform 16 is connected with the inner wall of the treatment tank 1 in a sliding manner, the moving platform 16 and the connecting rod 17 can be driven to reciprocate through the forward and reverse rotation of the screw rod 15, and then the stirring plate 13 is driven to move.
When it is necessary to collect the magnetic metal on both sides of the bottom of the processing bath 1, it is necessary to first withdraw the sealing block 20 while increasing the lead of the moving stage 16 for accomplishing the inversion of the agitating plate 13. When the sealing block 20 is drawn out, the magnetic metals piled on two sides of the treatment pool 1 can slide into the collecting tank 18, meanwhile, the collecting port 19 can be communicated with the inside of the treatment pool 1, the wastewater in the treatment pool 1 can also flow out along the collecting port 19, the stirring plate 13 continuously reciprocates at the bottom of the treatment pool 1 in the process, the non-adsorbed magnetic metals are pushed into the collecting tank 18, the stirring plate 13 can realize the overturning and dumping actions when moving to two sides of the treatment pool 1, and the magnetic metals adhered on the stirring plate 13 can be further poured into the collecting tank 18. And often still need set up some meshs on stirring board 13 and select bigger magnetic metal to push to both sides, but the meshs probably also can block some magnetic metal on it when reciprocating motion, also can let some magnetic metal that block in the meshs slide into collecting vat 18 through the action that stirring board 13 topples over, accomplish the collection as much as possible to bigger magnetic metal.
Referring to fig. 11 and 12, as a way for the stirring plate 13 to turn over when moving to the two sides of the processing tank 1, a connection port 21 is formed on the stirring plate 13, a sliding block 22 is slidably connected to the connection port 21, and the sliding block 22 is rotatably connected to the connecting rod 17; an upper sliding rod 23 and a lower sliding rod 24 are arranged at both ends of the stirring plate 13; the side wall of the treatment tank 1 is provided with an upper sliding groove 25 and a lower sliding groove 26; the upper sliding rod 23 is slidably connected with the upper sliding groove 25, and the lower sliding rod 24 is slidably connected with the lower sliding groove 26; the lower slide groove 26 is linear, the upper slide groove 25 is divided into a linear portion and a bent portion 27, and the bent portion 27 is bent centering on an end portion of the lower slide groove 26.
When the stirring function and the function of pushing a part of the large magnetic metal that cannot be lifted up to both sides of the bottom of the treatment tank 1 are required to be realized, the movable stage 16 does not move to the limit lead, and the upper slide rod 23 only moves in the linear portion of the upper slide groove 25.
Therefore, when the moving stage 16 reciprocates in this portion, the connecting rod 17 and the slide 22 are driven to finally drive the stirring plate 13 to reciprocate. Further, since the upper and lower sliding rods at both ends of the agitating plate 13 are respectively restricted by the upper and lower sliding grooves, and the upper sliding rod 23 moves only at the linear portion of the upper sliding groove 25, the agitating plate 13 is always kept in a vertical state, and the slider 22 and the connection port 21 do not slide relatively.
When it is desired to further dump the magnetic metal stuck on the agitating plate 13 into the collecting tank 18 by the above-mentioned action of overturning and dumping, the moving stage 16 moves to the limit lead, at which the upper slide bar 23 moves at the bent portion 27 of the upper slide groove 25.
Similarly, the moving platform 16 can drive the stirring plate 13 to move, when the upper sliding rod 23 of the stirring plate 13 moves to the bent part 27, the lower sliding rod 24 reaches the maximum lead, at this time, the connecting rod 17 continues to move, so that the sliding block 22 also slides in the connecting port 21, thereby releasing the degree of freedom between the connecting rod 17 and the stirring plate 13, the stirring plate 13 starts to turn over with the lower sliding rod 24 as a central shaft, at this time, the upper half part of the stirring plate 13 inclines towards the collecting tank 18, and the lower end of the stirring plate 13 also slightly sinks into the collecting tank 18, thereby realizing the complete dumping action. Since the sealing block 20 is now already withdrawn, the lower end of the stirring plate 13 is slightly recessed in the collection groove 18 without interference.
Referring to fig. 14, as a further embodiment of the present invention, the lower end of the stirring plate 13 is closely attached to the bottom of the treatment tank 1, and the lower end of the stirring plate 13 is provided with a shovel head 14.
The shovel head 14 can further shovel the magnetic metal attached to the bottom of the treatment tank 1, so that the magnetic metal can be conveniently lifted and adsorbed or pushed into the collecting tanks 18 on two sides.
Referring to fig. 1, as a further embodiment of the present invention, a shielding plate 28 is disposed on the top of the treatment tank 1.
Since the magnetic metal is thrown out by centrifugal force, a shielding plate 28 is required to cover the top of the device to prevent the magnetic metal from splashing.
Example two:
referring to fig. 13 to 15, as another implementation form of the agitating plate 13 capable of turning when moving to both sides of the treatment tank, the present embodiment is different from the first embodiment in that:
a connecting port 21 is formed in the stirring plate 13, a sliding block 22 is connected in the connecting port 21 in a sliding manner, and the sliding block 22 is rotatably connected with the connecting rod 17; an upper sliding rod 23 and a lower sliding rod 24 are arranged at both ends of the stirring plate 13; the side wall of the treatment tank 1 is provided with an upper sliding groove 25 and a lower sliding groove 26; the upper sliding rod 23 is slidably connected with the upper sliding groove 25, and the lower sliding rod 24 is slidably connected with the lower sliding groove 26; a telescopic structure is arranged between the upper sliding rod 23 and the lower sliding rod 24; the side wall of the treatment tank 1 is provided with an upper sliding groove 25 and a lower sliding groove 26, the upper sliding groove 25 and the lower sliding groove 26 are both linear, and the lengths of the two ends of the upper sliding groove 25 are both larger than those of the lower sliding groove 26.
When it is necessary to perform the above-mentioned stirring function and the function of pushing a part of the large magnetic metal which cannot be lifted up to both sides of the bottom of the treatment tank 1, the moving stage 16 does not move to the limit lead, and the agitating plate 13 can perform the reciprocating motion to perform the above-mentioned function, along with the embodiment.
When it is necessary to further pour the magnetic metal stuck on the agitating plate 13 into the collecting tank 18 by the above-mentioned action of overturning and pouring, the moving stage 16 moves to the limit lead.
During the movement of the mobile station 16 to the limit lead, the lower slide 24 will first move to the maximum lead, while the upper slide 23 can continue to move forward. At this time, the link 17 continues to move, so that the slider 22 also slides in the connecting port 21, thereby releasing the degree of freedom between the link 17 and the agitating plate 13, and the telescopic structure provided between the upper slide bar 23 and the lower slide bar 24 also expands simultaneously. At this time, the upper half part of the stirring plate 13 is inclined toward the collecting groove 18, and the lower end of the stirring plate 13 is slightly sunk into the collecting groove 18, so that the stirring plate 13 is completely dumped.

The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed.
