During each cleaning, the equipment must be disassembled and taken down, which is very inconvenient to operate, the disassembly frequency is high, and the technical problems of manpower consumption are as follows: Figure 1-Figure 7 As shown, the following preferred technical solutions are provided:

[0037] A timed backwashing device based on the treatment of old ferric chloride liquid comprises an anode chamber 1 and a cathode chamber 2 connected to the anode chamber 1, the anode chamber 1 and the cathode chamber 2 are fixedly connected by a connecting plate 3, and the connecting plate 3 is arranged in the middle between the anode chamber 1 and the cathode chamber 2, a first connecting valve 4 and a second connecting valve 8 are fixedly installed between the anode chamber 1 and the cathode chamber 2, and the first connecting valve 4 and the second connecting valve 8 are respectively installed at the two ends of the bottom of the connecting plate 3, the two ends of the first connecting valve 4 and the second connecting valve 8 are respectively connected and fixedly installed with an anti-corrosion pump 5, and the anti-corrosion pump 5 is embedded and fixedly installed on the outer walls at both ends of the inner lower ends of the anode chamber 1 and the cathode chamber 2, the anti-corrosion pump 5 is respectively connected to the inner cavity of the anode chamber 1 and the cathode chamber 2, a driving component 6 is installed in the inner cavity of the connecting plate 3, the driving component 6 is used to start and close the first connecting valve 4 and the second connecting valve 8 respectively, and a control panel 7 is fixedly installed on the outer wall of the connecting plate 3, and the control panel 7 is used to control and start and stop the power structure in the backwashing device.

[0038] A middle inner groove 31 is provided in the middle of the inner cavity of the connecting plate 3, a motor embedding groove 32 is provided in the middle of one end of the top surface of the connecting plate 3, and bottom circular holes 33 are respectively provided in the middle of both ends of the bottom surface of the connecting plate 3, and the motor embedding groove 32 and the bottom circular holes 33 are respectively connected to the middle inner groove 31.

[0039] The driving component 6 includes a motor 61 and a first gear 62 fixedly mounted on the output end of the motor 61, and the motor 61 is fixedly mounted in the motor embedding groove 32, the first gear 62 is arranged at one end of the inner cavity of the middle inner groove 31, and a second gear 63 is movably mounted at the middle of the other end of the inner cavity of the middle inner groove 31, and the first gear 62 and the second gear 63 are connected by a transmission belt 64, one end of the transmission belt 64 is meshed and sleeved on the outer periphery of the first gear 62, and the other end of the transmission belt 64 is meshed and sleeved on the outer periphery of the second gear 63, and the control panel 7 is electrically connected to the motor 61.

[0040] The first connecting valve 4 includes a first valve body shell 41 and a connecting pipe 42 which is respectively connected and sealed and fixedly installed at the opening ends of both ends of the first valve body shell 41. A first ball valve 43 is movably installed in the inner cavity of the first valve body shell 41, and the upper end of the first ball valve 43 is fixedly installed at the middle of the bottom surface of the second gear 63.

[0041] The second connecting valve 8 includes a second valve body shell 81 and a second ball valve 82 movably installed in the inner cavity of the second valve body shell 81, and the upper end of the second ball valve 82 is fixedly installed at the middle of the bottom surface of the first gear 62, and the first ball valve 43 and the second ball valve 82 are staggered at 90 degrees.

[0042] Specifically, when the anode chamber 1 and the cathode chamber 2 are in normal use, the motor 61 can be started through the control panel 7, and the output end of the motor 61 rotates 90 degrees. Under the transmission action of the transmission belt 64, the second gear 63 can be driven to rotate through the first gear 62. Since the first ball valve 43 and the second ball valve 82 are staggered at 90 degrees, the first ball valve 43 can achieve the connection between the anode chamber 1 and the cathode chamber 2, and the second ball valve 82 can block the connection between the cathode chamber 2 and the anode chamber 1. At this time, the anti-lock brakes at both ends of the second connecting valve 8 are respectively started through the control panel 7. The corrosion pump 5 can realize the treatment of the old ferric chloride liquid. When the anode chamber 1 needs to be cleaned, the motor 61 can be started through the control panel 7. The output end of the motor 61 rotates ninety degrees, so that the first ball valve 43 can seal the anode chamber 1 to the cathode chamber 2, and the second ball valve 82 can open the cathode chamber 2 to the anode chamber 1. The anode is rinsed clean with the acid water of the cathode. At the same time, the start time is set through the control panel 7, and the anode chamber 1 can be automatically cleaned. While saving manpower, it also greatly reduces the disassembly frequency of the anode chamber 1, which is convenient to use.

[0043] Furthermore, by providing the transmission belt 64, the device can simultaneously close and open the first connecting valve 4 and the second connecting valve 8 using only one motor 61, thereby saving use and manufacturing costs.

[0044] In order to solve the technical problem of how to discharge the acid water in the inner cavity of the first ball valve 43 or the second ball valve 82 when the first ball valve 43 or the second ball valve 82 is closed, to prevent the acid water from corroding and damaging the first ball valve 43 or the second ball valve 82 and reducing its service life, as shown in FIG. Figure 1-Figure 13 As shown, the following preferred technical solutions are provided:

[0045] A spherical inner groove 411 is provided in the middle part of the inner cavity of the first valve body shell 41, and water holes 412 are respectively provided on the middle outer walls on both sides of the first valve body shell 41, and the water holes 412 are respectively connected with the spherical inner groove 411, a top insertion hole 413 is provided in the middle part of the top surface of the first valve body shell 41, and the top insertion hole 413 is connected with the spherical inner groove 411, a bottom through hole 414 is provided in the middle part of the bottom surface of the inner cavity of the spherical inner groove 411, and a compressed air circular groove 415 is provided in the middle inner cavity of the lower end of the first valve body shell 41, and the lower end part of the bottom through hole 414 is connected with the compressed air circular groove 415, and a connecting plate 416 is fixedly installed in the middle part of the top surface of the inner cavity of the compressed air circular groove 415.

[0047] The first ball valve 43 includes a connecting shaft 431 and a ball valve body 432 fixedly installed on the bottom surface of the connecting shaft 431, and a connecting sleeve 433 is inserted and fixedly installed in the middle of the bottom surface of the ball valve body 432, and a telescopic sliding column 434 is slidably embedded in the inner part of the connecting sleeve 433, a piston 435 is fixedly installed on the bottom surface of the telescopic sliding column 434, and the piston 435 is sealingly slidably installed in the inner cavity of the compressed air circular groove 415.

[0048] A two-way through hole 4321 is provided in the middle of the ball valve body 432, and anti-corrosion sealing gaskets 4322 are respectively embedded and fixedly installed on the middle outer walls on both sides of the ball valve body 432, and a one-way valve 4323 is embedded and fixedly installed on the middle outer wall of one side of the ball valve body 432. A receiving groove 4324 is provided in the middle of the bottom surface of the inner cavity of the two-way through hole 4321, and a bottom through hole 4325 is provided in the middle of the bottom surface of the ball valve body 432, and the bottom through hole 4325 is connected to the receiving groove 4324, and an air bag 4326 is installed in the inner cavity of the receiving groove 4324, and an anti-corrosion coating is provided on the surface of the air bag 4326. The setting of the one-way valve 4323 can ensure that after the two-way through hole 4321 is blocked, the acid water can be discharged outward through the one-way valve 4323.

[0049] The connecting sleeve 433 is fixedly installed in the inner cavity of the bottom through hole 4325, and a bottom slide groove 4331 is arranged in the middle of the bottom surface of the connecting sleeve 433. The volume of the bottom slide groove 4331 is set to be much smaller than the volume of the compressed gas circular groove 415, so as to ensure that the airbag 4326 is fully expanded, and limiting slide grooves 4332 are respectively arranged on the inner walls on both sides of the inner cavity of the bottom slide groove 4331, and an outer through hole 4333 is arranged in the middle of the inner cavity top surface of the bottom slide groove 4331, and the outer through hole 4333 is connected to the airbag 4326. The telescopic sliding column 434 includes a sliding column body 4341 and outer sliding grooves 4331 and 4332 are respectively fixedly installed on both sides of the upper end of the sliding column body 4341. The limiting protrusion 4342 is on the wall, and the outer peripheral wall of the sliding column body 4341 is provided with an inclined slide groove 4343, and the inclined slide groove 4343 is set at 90 degrees as a whole, which ensures that after the ball valve body 432 rotates 90 degrees, the sliding column body 4341 can move down the length of the inclined slide groove 4343, and a middle through hole 4344 is provided in the middle of the sliding column body 4341, and the piston 435 includes a middle pressure plate 4351 and a rubber ring 4352 fixedly sleeved on the outer peripheral wall of the middle pressure plate 4351, and a plate body through hole 4353 is provided in the middle of the middle pressure plate 4351, and the plate body through hole 4353 is communicated with the middle through hole 4344.

[0050] Specifically, the limiting balls 4162 are respectively arranged in the inclined grooves 4343. When the second gear 63 drives the ball valve body 432 to rotate through the connecting shaft 431 to close the spherical inner groove 411, the ball valve body 432 can simultaneously drive the connecting sleeve 433 to rotate. At this time, the connecting sleeve 433 will rotate relative to the connecting plate 416. At this time, under the limiting action of the limiting grooves 4332 and the limiting protrusions 4342, the telescopic slide column 434 will also rotate with the connecting sleeve 433. Under the limiting action of the limiting balls 4162 and the inclined grooves 4343, the telescopic slide column 434 can be driven to move downward as a whole, so that the piston 435 can squeeze the telescopic slide column 434. The inert gas in the inner cavity of the compressed air groove 415 can be pressed into the airbag 4326 from the plate body through hole 4353, the middle through hole 4344 and the outer through hole 4333 respectively, so that the airbag 4326 as a whole can be continuously expanded to press out the acid water in the two-way through hole 4321. Similarly, when the ball valve body 432 rotates in the opposite direction, the airbag 4326 can be recovered. The working principle of the second connecting valve 8 is the same. This setting is not only fully automatic, but also cleverly utilizes the power of the ball valve body 432 when it rotates, and also ensures that when the first ball valve 43 or the second ball valve 82 is closed, no acid water will remain in its inner cavity, thereby improving the service life of the equipment.

[0051] In order to further better explain the above embodiment, the present invention also provides an embodiment, based on the backwashing process of the timed backwashing equipment for treating the old ferric chloride solution, comprising the following steps:

[0052] Step 1: Set the start time through the control panel 7. When the anode chamber 1 and the cathode chamber 2 are in normal use, the motor 61 can be started through the control panel 7. The output end of the motor 61 rotates 90 degrees, and the first gear 62 can drive the second gear 63 to rotate through the transmission belt 64.

[0053] Step 2: When the first ball valve 43 is in a state where the anode chamber 1 is connected to the cathode chamber 2, the second ball valve 82 blocks the cathode chamber 2 from the anode chamber 1. At this time, the anti-corrosion pumps 5 located at both ends of the second connecting valve 8 are respectively started through the control panel 7 to achieve the treatment of the old ferric chloride solution;

[0054] Step 3: When the anode chamber 1 needs to be cleaned, the motor 61 can be started through the control panel 7, and the output end of the motor 61 rotates in the opposite direction by 90 degrees;
