[0014] The present invention provides an integrated petrochemical wastewater treatment device. It has the following beneficial effects: (1) The present invention uses a U-shaped block, a cylinder, a fork-shaped slide bar, a scraper, a semi-arc block, an arc-shaped spring bar, a ring, a roller and a semi-arc spring sheet in conjunction with a weighted ball. Under the elastic force of the arc-shaped spring bar, the ring drives the cylinder to move back and forth left and right, and the cylinder moves back and forth left and right in the U-shaped block. The cylinder drives the fork-shaped slide bar to move back and forth left and right, and the fork-shaped slide bar drives the scraper to move back and forth left and right, so that the chamfer of the scraper reciprocates left and right to scrape away impurities on the filter plate, so that impurities in petrochemical wastewater will not accumulate on the filter plate, preventing wastewater from being treated. When the treatment device is filtering, impurities in the wastewater accumulate together, resulting in poor filtering effect of the equipment, and the semi-arc shrapnel rebounds the counterweight ball under the action of elastic force, and the counterweight ball hits the roller, causing the roller to vibrate to a certain amplitude.

The H-shaped rod drives the half-open box to change from a straight line to an eight-shaped shape. When the half-open box is in the eight-shaped shape, larger particles of impurities in the wastewater will enter the half-open box, and the filter screen of the half-open box will discharge the wastewater, so that the half-open box reciprocates to deform to collect larger particles of impurities in the wastewater, so that larger particles of impurities in the petrochemical wastewater will not accumulate on the filter plate, thereby preventing the accumulation of larger particles of impurities in the petrochemical wastewater in the wastewater treatment device during filtration, resulting in poor equipment use effect. In addition, under the action of the baffle bar's own gravity and the elastic force of the arc-shaped spring sheet, when the half-open box is in the eight-shaped shape, the baffle bar rotates downward on the half-open box. During the rotation of the baffle bar, the impurities on the baffle bar are shaken off into the half-open box, thereby preventing the wastewater treatment device from overflowing when collecting larger particles of impurities in the petrochemical wastewater, resulting in poor collection effect.

[0016] (3) The present invention arranges the oil absorption device so that the rectangular box, oil absorption cotton, sliding column, horizontal plate, L-shaped plate, long cylinder, T-shaped column, U-shaped frame and rotating roller cooperate with the rubber strip. The T-shaped column drives the long cylinder to move downward, the long cylinder drives the L-shaped plate to move downward, the L-shaped plate drives the horizontal plate to move downward, the horizontal plate drives the sliding column to move downward, the sliding column moves downward in the sliding hole of the T-shaped rail plate, and the spring in the sliding hole of the T-shaped rail plate contracts at the beginning, so that the horizontal plate gently squeezes the rotating oil absorption cotton downward, the oil absorption cotton discharges waste water, and the oil pollution stays in the oil absorption cotton, so as to prevent the wastewater treatment device from inconveniently treating the wastewater oil pollution during filtration, resulting in poor treatment effect of petrochemical wastewater oil pollution, and the rubber strip contacts the oil absorption cotton, and under the action of friction, the rotating roller rotates in the U-shaped frame, so that the rubber strip on the rotating roller rotates and squeezes the oil absorption cotton, so that the oil absorption cotton will not be squeezed and damaged during squeezing, so as to prevent the wastewater treatment device from damaging the oil absorption cotton during squeezing, resulting in poor oil absorption effect.

The heat dissipation shell is fixed on the left side of the top surface of the casing 1. A servo motor is fixedly installed on the top of the heat dissipation shell. The servo motor shaft is fixed on the top surface of the rotating rod 7. The rotating rod 7 penetrates and is rotatably installed on the left side of the top surface of the casing 1. The rotating rod 7 is arranged inside the left chamber of the casing 1. A threaded opening is provided at the bottom of the outer wall of the rotating rod 7. The filter plate 9 is meshed with the threaded opening of the rotating rod 7. A sliding hole is provided on the top surface of the T-shaped rail plate 8. The casing A groove is arranged on the bottom surface of the right chamber 1, and a sewage outlet is arranged in the middle of the bottom surface of the groove of the casing 1.

The scraper 17 is arranged above the filter plate 9. A square opening is opened on the top surface of the scraper 17. The chamfer of the scraper 17 reciprocates to scrape off the impurities on the filter plate 9, so that the impurities of the petrochemical wastewater will not accumulate on the filter plate 9, and the impurities of the wastewater treatment device will not accumulate together when filtering, resulting in poor filtering effect of the equipment.

[0021] A roller 21 is installed on the top surface of the scraper 17. The roller 21 is arranged inside the square opening of the scraper 17. A plurality of grooves are arranged on the outer wall of the roller 21. The roller 21 is arranged above the filter plate 9. A chamber is arranged inside the roller 21.

The filter plate 9 vibrates out the wastewater impurities in the mesh, so as to avoid the impurities of the petrochemical wastewater being blocked in the mesh of the filter plate 9 during filtering in the wastewater treatment device, resulting in poor filtering effect.

[0022] When in use, petrochemical wastewater enters the water inlet pipe 4, and the water inlet pipe 4 transports the wastewater to the left chamber of the casing 1. The support plate 3 on the casing 1 supports the equipment. At the same time, the servo motor of the drive module 6 is started by electric wires, and the servo motor shaft starts to rotate back and forth. The servo motor shaft drives the rotating rod 7 to rotate back and forth, and the rotating rod 7 drives the stirring fan 10 to rotate back and forth. The stirring fan 10 stirs the flowing petrochemical wastewater evenly, and the threaded opening of the rotating rod 7 drives the filter plate 9 to rotate back and forth. The filter plate 9 is restricted by the T-shaped track plate 8, and the filter plate 9 reciprocates up and down on the threaded opening of the rotating rod 7. The filter plate 9 moves up and down on the T-shaped track plate 8. The filter plate 9 moves back and forth, and the solid impurities in the petrochemical wastewater are filtered out during the up and down reciprocating movement. The filtered petrochemical wastewater passes through the square opening of the casing 1, and the petrochemical wastewater enters the right chamber of the casing 1. When the petrochemical wastewater is accumulated, the sediment of the petrochemical wastewater will fall into the groove of the casing 1, and the petrochemical wastewater rises in the right chamber of the casing 1. The honeycomb graphite plate 12 of the casing 1 filters the harmful substances in the petrochemical wastewater, and the outlet pipe 5 on the casing 1 discharges the purified petrochemical wastewater.

At the same time, the round cover of the sewage outlet can be rotated to open, which is convenient for the staff to clean the sediment of the wastewater. When filtering petrochemical wastewater, impurities in the petrochemical wastewater will accumulate together, which can easily cause poor filtering effect of the equipment. When the filter plate 9 moves up and down on the T-shaped track plate 8, the filter plate 9 drives the scraper 17 to move up and down, and the scraper 17 drives the fork-shaped slide bar 16 to move up and down. The fork-shaped slide bar 16 slides up and down in the cylinder 15. The spring in the cylinder 15 starts to stretch and contract reciprocally. At the same time, the T-shaped track plate 8 supports the semi-arc block 18, and the semi-arc block 18 supports the arc spring bar 19. The arc The spring bar 19 supports the ring 20. Under the elastic force of the arc spring bar 19, the ring 20 drives the cylinder 15 to move back and forth. The cylinder 15 moves back and forth in the U-shaped block 11. The cylinder 15 drives the fork-shaped slide bar 16 to move back and forth. The fork-shaped slide bar 16 drives the scraper 17 to move back and forth, so that the chamfer of the scraper 17 scrapes off the impurities on the filter plate 9 back and forth, so that the impurities of the petrochemical wastewater will not accumulate on the filter plate 9, and the impurities of the petrochemical wastewater are prevented from accumulating together when the filter plate 9 moves up and down for filtration, thereby avoiding the problem of poor filtering effect of the equipment caused by the accumulation of impurities in the wastewater when the wastewater treatment device is filtering.

[0023] In the process that the fork-shaped slide bar 16 drives the scraper 17 to move back and forth left and right, the scraper 17 drives the roller 21 to move back and forth left and right. Under the action of friction, the roller 21 rotates back and forth left and right on the filter plate 9, and the roller 21 drives the semi-arc spring piece 22 to rotate back and forth. The roller 21 drives the counterweight ball 23 to rotate back and forth left and right. The counterweight ball 23 hits the semi-arc spring piece 22 during the movement. The semi-arc spring piece 22 rebounds the counterweight ball 23 under the action of elastic force, and the counterweight ball 23 hits the roller 21, so that the roller 21 generates a certain vibration amplitude, and the roller 21 transmits the vibration to the scraper 17, so that the scraper 17 vibrates and scrapes off the impurities on the filter plate 9. At the same time, the roller 21 transmits the vibration to the filter plate 9, and the filter plate 9 vibrates out the wastewater impurities in the mesh to prevent the impurities of the petrochemical wastewater from being blocked in the filter plate 9, thereby avoiding the problem that the impurities of the petrochemical wastewater are blocked in the mesh of the filter plate 9 when the wastewater treatment device is filtering, causing poor filtering effect.

The horizontal plate 144 gently presses the rotating oil-absorbing cotton 142 downward, and the oil-absorbing cotton 142 discharges the wastewater, allowing the oil to remain in the oil-absorbing cotton 142, thereby avoiding the inconvenience of the wastewater treatment device in handling the wastewater oil during filtration, resulting in poor treatment effect of the petrochemical wastewater oil.

[0027] A U-shaped frame 148 is fixed to the bottom surface of the horizontal plate 144, and rollers 149 are rotatably installed on the left and right sides of the inner wall of the U-shaped frame 148.

[0028] While the cylinder 15 drives the fork-shaped slide bar 16 to move back and forth, the fork-shaped slide bar 16 drives the L-shaped rod 131 to move back and forth, the L-shaped rod 131 drives the H-shaped rod 132 to move back and forth, the H-shaped rod 132 is restricted by the hollow ring 133, the H-shaped rod 132 drives the hollow ring 133 to move upward, the H-shaped rod 132 reciprocates to change from a straight line to an eight-shaped shape, the H-shaped rod 132 drives the half-open box 134 to reciprocate to change from a straight line to an eight-shaped shape, when the petrochemical wastewater enters the casing 1, the petrochemical wastewater enters the half-open box 134 in the straight line, and the filter screen of the half-open box 134 will Wastewater is discharged, and larger particles of impurities in the wastewater will be in the half-open box 134. When the half-open box 134 is in an eight-shaped shape, larger particles of impurities in the wastewater will enter the half-open box 134, and the filter screen of the half-open box 134 will discharge the wastewater again, so that the half-open box 134 reciprocates to collect larger particles of impurities in the wastewater, so that larger particles of impurities in the petrochemical wastewater will not accumulate on the filter plate 9, and larger particles of impurities will be prevented from accumulating on the filter plate 9, thereby avoiding the problem of larger particles of impurities in the petrochemical wastewater accumulating in the equipment during filtration of the wastewater treatment device, resulting in poor equipment use effect.

[0029] While the H-shaped rod 132 drives the half-open box 134 to change from a straight line to an eight-shaped shape, the half-open box 134 drives the strip plate 135 to move back and forth up and down, the strip plate 135 drives the arc spring sheet 136 to move back and forth up and down, and the arc spring sheet 136 drives the baffle 137 to move back and forth up and down. Under the action of the self-gravity of the baffle 137 and the elastic force of the arc spring sheet 136, when the half-open box 134 is in the eight-shaped shape, the baffle 137 rotates downward on the half-open box 134. During the rotation process, the baffle 137 shakes off the impurities on the baffle 137 into the half-open box 134, preventing the larger particles of impurities collected by the half-open box 134 from overflowing, thereby avoiding the problem of poor collection effect caused by overflow when the wastewater treatment device collects larger particles of impurities in petrochemical wastewater.

[0030] While the rotating rod 7 drives the stirring fan 10 to rotate forward and backward, the stirring fan 10 drives the rectangular box 141 to rotate forward and backward, and the rectangular box 141 drives the oil-absorbing cotton 142 to rotate forward and backward. The oil-absorbing cotton 142 absorbs the oil in the petrochemical wastewater during the forward and backward reciprocating rotation. At the same time, the filter plate 9 drives the T-shaped column 147 to move up and down, and the T-shaped column 147 moves up and down in the long cylinder 146. When the T-shaped column 147 moves to the bottom of the long cylinder 146, the T-shaped column 147 drives the long cylinder 146 to move downward, and the long cylinder 146 drives the L-shaped plate 145 to move downward, and the L-shaped plate 145 drives the horizontal plate 14 4 moves downward, the cross plate 144 drives the sliding column 143 to move downward, and the sliding column 143 moves downward in the sliding hole of the T-shaped rail plate 8. The spring in the sliding hole of the T-shaped rail plate 8 shrinks at the beginning, so that the cross plate 144 gently squeezes the rotating oil-absorbing cotton 142 downward. The oil-absorbing cotton 142 is made of melt-blown polypropylene and only absorbs oil but not water. During the squeezing process of the cross plate 144, the oil-absorbing cotton 142 discharges waste water, leaving the oil in the oil-absorbing cotton 142, preventing the wastewater treatment device from being inconvenient to remove oil, thereby avoiding the problem that the wastewater treatment device is inconvenient to handle the oil in the wastewater during filtering, resulting in poor treatment effect of the oil in the petrochemical wastewater.

[0031] While the L-shaped plate 145 drives the cross plate 144 to move downward, the cross plate 144 drives the U-shaped frame 148 to move downward, the U-shaped frame 148 drives the roller 149 to move downward, the roller 149 drives the rubber strip 1410 to move downward, and the rubber strip 1410 contacts the oil-absorbing cotton 142. Under the action of friction, the roller 149 rotates in the U-shaped frame 148, so that the rubber strip 1410 on the roller 149 rotates to squeeze the oil-absorbing cotton 142, so that the oil-absorbing cotton 142 will not be squeezed and damaged during squeezing, preventing the equipment from damaging the oil-absorbing cotton 142 during squeezing, thereby avoiding the problem of poor oil absorption effect caused by the wastewater treatment device damaging the oil-absorbing cotton 142 during squeezing.
