Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and specifically to a printing and dyeing wastewater treatment device. Background Art

[0002] Printing and dyeing wastewater treatment devices are mainly used to remove harmful substances in the printing and dyeing process, such as dyes, chemical auxiliaries, and organic matter, in order to meet the discharge standards. The patent with the patent announcement number CN207130106U relates to a printing and dyeing wastewater treatment device, including a contact oxidation tower, a flotation reactor, a printing and dyeing wastewater adjustment tank, a base, a water pump, a pH adjustment tank, a hydrolysis acidification tank, a water outlet, a support frame, a filter press, a lifting pipe, and a sealing cover. The printing and dyeing wastewater adjustment tank is connected to the flotation reactor through a water pump. The flotation reactor is installed on the left side of the contact oxidation tower. There is a contact oxidation tower directly above the pH adjustment tank. There is a lifting pipe on the right side of the contact oxidation tower. The hydrolysis acidification tank is connected to the contact oxidation tower through the lifting pipe. The pH adjustment tank is provided on the base of this patent. Combining the cooperation of the pH adjustment bin, the reflux machine, and the pH adjustment tank can adjust the pH value of the treated printing and dyeing wastewater, and it will not affect the pH value of the water area after discharge.

[0003] In the above patent, by combining the cooperation of the pH adjustment bin, the reflux machine, and the pH adjustment tank, the pH value of the treated printing and dyeing wastewater can be adjusted, and it will not affect the pH value of the water area after discharge. After the wastewater is stirred with the medicament, it needs to be left standing for a long time. Since adding wastewater into the inside of the standing box will stir up the originally standing wastewater, it takes a longer time to stand, which relatively affects the working efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a printing and dyeing wastewater treatment device, which solves the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A printing and dyeing wastewater treatment device includes a standing box, and a top cover is fixedly installed on the top of the standing box; An inlet, the inlet is opened on the surface of the top cover, and the inlet is used to introduce wastewater into the inside of the standing box; A guide plate is rotatably installed on the inner wall of the standing box. A flow dividing plate is fixedly installed on the top of the guide plate. A rotating plate one is rotatably installed on the top of the flow dividing plate; so that when the wastewater flows into the inside of the standing box, it will not directly drip into the water surface, preventing the wastewater from dripping and hitting the water surface; A water level caliper slides through the inner and outer walls of the top cover. The bottom of the water level caliper is rotatably connected to the top of the rotating plate one. The water level caliper is used to observe the water flow rate of the water inflow volume at the inlet; A water baffle, which is slidably installed at the bottom of the top cover and is used to block part of the water inlet; A slope block is slidably installed on the surface of the first rotating plate. The slope block is slidably connected to the water baffle. A separation device for removing the sediment at the bottom of the static box and a protection device for ensuring the normal operation of the separation device are arranged inside the housing.

[0006] According to the above technical solution, a return spring is arranged between the guide plate and the static box. The water baffle contacts the water inlet, and when there is no water flow at the top of the guide plate, the return spring drives the guide plate to rotate upward.

[0007] According to the above technical solution, the separation device includes a pushing plate, a sliding plate, an L-shaped plate and a square plate. The pushing plate is slidably installed at the bottom of the inner wall of the static box. A driving device is arranged inside the pushing plate. The sliding plate is slidably installed inside the pushing plate. Water flow holes are formed on the surfaces of the sliding plate and the pushing plate. The L-shaped plate is fixedly installed at the top of the sliding plate. The square plate is fixedly installed on the surface of the pushing plate. The water flow holes on the surface of the pushing plate are blocked, so that when the pushing plate moves at a specified moving speed, the flocs that have settled at the bottom will be pushed and collected.

[0008] According to the above technical solution, the separation device further includes a limiting rod, a sliding long rod, an arc-shaped rod and a cross rubber valve. The limiting rod is fixedly installed at the bottom of the guide plate. A limiting groove is formed at the top of the square plate. The sliding long rod is fixedly installed on the inner wall of the static box. The arc-shaped rod is fixedly installed at one end of the sliding long rod close to the L-shaped plate. A circular hole is formed on the surface of the pushing plate. The cross rubber valve is fixedly installed on the inner wall of the circular hole on the side close to the square plate. When the sliding plate moves downward, the water inside the pushing plate will be discharged through the cross rubber valve.

[0009] According to the above technical solution, a first spring is arranged between the sliding plate and the pushing plate. The L-shaped plate contacts the arc-shaped rod. When the sliding plate is no longer squeezed, the first spring drives the sliding plate to reset.

[0010] According to the above technical solution, the protection device includes a second rotating plate, a sealing rubber, a transmission long rod and a positioning block. The second rotating plate is rotatably installed on the surface of the static box. The sealing rubber is fixedly installed on the inner wall of the static box. The transmission long rod is fixedly installed on the side of the pushing plate close to the second rotating plate. The positioning block is fixedly installed at the top of the square plate. After the sealing rubber is squeezed, it deforms, so that the square plate and the static box are sealed.

[0011] According to the above technical solution, the protection device further includes a rotating rod, a triangular block, an L-shaped rod and a connecting rod. The rotating rod is rotatably installed on the inner wall of the static box. The triangular block is fixedly installed at one end of the rotating rod away from the second rotating plate. The L-shaped rod is rotatably installed on the inner wall of the static box. One end of the connecting rod is rotatably connected to the L-shaped rod, and the other end of the connecting rod is rotatably connected to the rotating rod. The rotating rod is driven by the first torsion spring to rotate downward, and the rotation of the rotating rod drives the triangular block to rotate downward and limit the positioning block.

[0012] According to the above technical solution, a first torsion spring is provided between the rotating rod and the static box, and a second torsion spring is provided between the second rotating plate and the static box. The rotating rod is driven by the first torsion spring to reset.

[0013] The present invention provides a printing and dyeing wastewater treatment device. It has the following beneficial effects: (1) In this invention, after the guide plate rotates, it will come into contact with the wastewater originally existing inside the static box, so that when the wastewater flows into the inside of the static box, it will not directly drip into the water surface. When the wastewater drips and impacts the water surface, the kinetic energy of the wastewater drop is converted into the fluctuation on the water surface, resulting in ripples on the water surface, reducing the time required for the mixed wastewater to precipitate, improving work efficiency. By moving the water level gauge downward, the operator can observe the flow rate of the wastewater flowing in through this device and can adjust the flow rate of the wastewater flowing into the device by himself, further ensuring that the flocs that have already precipitated are turned up, resulting in a longer precipitation time, and improving the practicability of the device. When the inclined block moves, it drives the water baffle to move towards the water inlet and block part of the water inlet, so that when the operator fails to reduce the flow rate in time, the device will automatically block the water inlet and reduce the flow rate, improving the comfort when the device is used.

[0014] (2) In this invention, when the water flow holes on the surface of the pushing plate are blocked, when the pushing plate moves at a specified moving speed, it will push and collect the flocs that have already precipitated at the bottom. When discharging the collected flocs, only the flocs collected inside will be discharged, and the water that has separated from the flocs will not be driven out, facilitating the discharge of the flocs settled at the bottom and improving the practicability of the device. When the sliding plate moves downward, it will discharge the water inside the pushing plate through the cross rubber valve, preventing the airtight seal between the sliding plate and the pushing plate from causing the sliding plate to fail to move up and down reciprocally normally, and improving the stability of the device during operation.

[0015] (3) In this invention, when the square plate moves, it will contact the sealing rubber. After being squeezed, the sealing rubber deforms, so that the space between the square plate and the static box is sealed, preventing water from flowing out and being wasted when removing flocculants, and ensuring the treatment effect of water quality treatment. After the rotating rod rotates and the triangular block no longer contacts the positioning block, the first torsion spring resets to drive the rotating rod to rotate downward. The rotation of the rotating rod drives the triangular block to rotate downward and limit the positioning block, further improving the sealing effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 5, an embodiment of the present invention is: a printing and dyeing wastewater treatment device, including a static box 1, and a top cover 2 is fixedly installed on the top of the static box 1; An inlet 3 is opened on the surface of the top cover 2, and the inlet 3 is used to introduce wastewater into the interior of the static box 1; A guide plate 4 is rotatably installed on the inner wall of the static box 1, a diversion plate 5 is fixedly installed on the top of the guide plate 4, and a first rotating plate 6 is rotatably installed on the top of the diversion plate 5; the kinetic energy of the dripping wastewater is converted into fluctuations on the water surface, resulting in ripples on the water surface sometimes, reducing the time required for the mixed wastewater to precipitate, and improving work efficiency; A water level gauge 7 slides through the inner and outer walls of the top cover 2, and the bottom of the water level gauge 7 is rotatably connected to the top of the first rotating plate 6. The water level gauge 7 is used to observe the water flow rate of the water inlet volume of the inlet 3, further ensuring that the flocs that have already precipitated are turned up, resulting in a longer time required for precipitation, and improving the practicability of the device; A water baffle 8 is slidably installed at the bottom of the top cover 2, and the water baffle 8 is used to block part of the inlet 3; An inclined block 9 is slidably installed on the surface of the first rotating plate 6, and the inclined block 9 is slidably connected to the water baffle 8, so that when the operator fails to reduce the flow rate in time, the device will automatically block the inlet 3 and reduce the flow rate, improving the comfort when the device is used.

[0020] A return spring 10 is arranged between the guide plate 4 and the static box 1, and the water baffle 8 is in contact with the inlet 3. When there is no water flow on the top of the guide plate 4, the return spring 10 drives the guide plate 4 to rotate upward.

[0021] During the operation of this embodiment: The wastewater mixed with the medicament is introduced into the interior of the static box 1 through the water inlet 3. The wastewater flowing downward is guided by the guide plate 4. The wastewater flows downward along the guide plate 4 and merges with the wastewater inside the static box 1. The flowing wastewater drives the guide plate 4 to rotate downward. After the guide plate 4 rotates, it will contact the wastewater originally existing inside the static box 1, preventing the wastewater from directly dripping into the water surface when flowing into the static box 1. When the wastewater drops and impacts the water surface, the kinetic energy of the wastewater drop is converted into the fluctuation on the water surface, resulting in ripples on the water surface, reducing the time required for the mixed wastewater to precipitate, and improving work efficiency. The rotation of the guide plate 4 drives the flow dividing plate 5 to rotate downward. The rotation of the flow dividing plate 5 drives the first rotating plate 6 to rotate downward. The rotation of the first rotating plate 6 drives the water level gauge 7 to move downward, enabling the operator to observe the flow rate of the wastewater flowing in through this device and adjust the flow rate of the wastewater flowing into the device by himself, further ensuring that the flocs that have already precipitated are not turned up, resulting in a longer precipitation time, and improving the practicality of the device. The downward movement of the first rotating plate 6 drives the inclined block 9 to move downward. The movement of the inclined block 9 drives the water blocking plate 8 to move toward the water inlet 3 and block part of the water inlet 3, so that when the operator fails to reduce the flow rate in time, this device will automatically block the water inlet 3 and reduce the flow rate, improving the comfort during the use of the device.

[0022] Please refer to Figures 1 - 8 , on the basis of the above embodiment, in another embodiment of the present invention, a separation device for removing the sediment at the bottom of the static box 1 and a protection device for ensuring the normal operation of the separation device are provided inside the housing 1. Among them, the separation device includes a pushing plate 111, a sliding plate 112, an L-shaped plate 113 and a square plate 114. The pushing plate 111 is slidably installed at the bottom of the inner wall of the static box 1. A driving device is provided inside the pushing plate 111. The sliding plate 112 is slidably installed inside the pushing plate 111. Flow holes are provided on the surfaces of both the sliding plate 112 and the pushing plate 111. The L-shaped plate 113 is fixedly installed on the top of the sliding plate 112. The square plate 114 is fixedly installed on the surface of the pushing plate 111, so that when discharging the collected flocs, only the flocs collected inside will be discharged, and the water that has separated from the flocs will not be driven out, facilitating the discharge of the flocs settled at the bottom and improving the practicality of the device.

[0023] The separation device further includes a limiting rod 115, a sliding long rod 116, an arc-shaped rod 117 and a cross rubber valve 118. The limiting rod 115 is fixedly installed at the bottom of the guide plate 4. A limiting groove is provided at the top of the square plate 114. The sliding long rod 116 is fixedly installed on the inner wall of the static box 1. The arc-shaped rod 117 is fixedly installed at one end of the sliding long rod 116 close to the L-shaped plate 113. A circular hole is provided on the surface of the pushing plate 111. The cross rubber valve 118 is fixedly installed on the inner wall of the circular hole on the side close to the square plate 114, preventing the airtight seal between the sliding plate 112 and the pushing plate 111 from causing the sliding plate 112 to not reciprocate up and down normally, and improving the stability of the device during operation.

[0024] A first spring is provided between the sliding plate 112 and the pushing plate 111. The L-shaped plate 113 contacts the arc-shaped rod 117. When the sliding plate 112 is no longer squeezed, the first spring drives the sliding plate 112 to reset.

[0025] The protection device includes a second rotating plate 121, a sealing rubber 122, a transmission long rod 123 and a positioning block 124. The second rotating plate 121 is rotatably installed on the surface of the static box 1. The sealing rubber 122 is fixedly installed on the inner wall of the static box 1. The transmission long rod 123 is fixedly installed on the side of the pushing plate 111 close to the second rotating plate 121. The positioning block 124 is fixedly installed at the top of the square plate 114, preventing water from flowing out and causing waste when removing flocs, and ensuring the treatment effect of water quality treatment.

[0026] The protection device further includes a rotating rod 125, a triangular block 126, an L-shaped rod 127 and a connecting rod 128. The rotating rod 125 is rotatably installed on the inner wall of the static box 1. The triangular block 126 is fixedly installed at one end of the rotating rod 125 away from the second rotating plate 121. The L-shaped rod 127 is rotatably installed on the inner wall of the static box 1. One end of the connecting rod 128 is rotatably connected to the L-shaped rod 127, and the other end of the connecting rod 128 is rotatably connected to the rotating rod 125, further improving the sealing effect of the device.

[0027] A first torsion spring is provided between the rotating rod 125 and the static box 1. A second torsion spring is provided between the second rotating plate 121 and the static box 1. The first torsion spring drives the rotating rod 125 to reset.

[0028] When this embodiment is working: The guide plate 4 rotates upwards to drive the limiting rod 115 to move upwards. After the limiting rod 115 moves, it no longer contacts the limiting groove. Subsequently, the driving device drives the pushing plate 111 to move. The movement of the pushing plate 111 drives the sliding plate 112 to move towards the sliding long rod 116. The movement of the pushing plate 111 drives the square plate 114 to move. The movement of the sliding plate 112 drives the L-shaped plate 113 to move towards the sliding long rod 116. The movement of the L-shaped plate 113 will contact the arc-shaped rod 117. Blocked by the arc-shaped rod 117, the L-shaped plate 113 moves downwards. The movement of the L-shaped plate 113 drives the sliding plate 112 to move downwards. After the sliding plate 112 moves, the water flow holes on its surface no longer coincide with the water flow holes on the surface of the pushing plate 111, so that the water flow holes on the surface of the pushing plate 111 are blocked. When the pushing plate 111 moves at a specified moving speed, it will push and collect the flocs that have settled at the bottom. When discharging the collected flocs, only the flocs collected inside will be discharged, and the water that has separated from the flocs will not be driven out, which is convenient for discharging the flocs settled at the bottom and improves the practicability of the device. When the pushing plate 111 moves towards the arc-shaped rod 117, the first spring resets to drive the sliding plate 112 to move upwards. The movement of the sliding plate 112 drives the L-shaped plate 113 to move upwards. After the L-shaped plate 113 moves, the water flow holes on the surface of the pushing plate 111 coincide with the water flow holes on the surface of the sliding plate 112. When the sliding plate 112 moves downwards, the water inside the pushing plate 111 will be discharged through the cross rubber valve 118, preventing airtightness between the sliding plate 112 and the pushing plate 111 from causing the sliding plate 112 to fail to move up and down reciprocally normally, and improving the stability of the device during operation.

[0029] The movement of the pushing plate 111 drives the L-shaped plate 113 to move towards the second rotating plate 121. The movement of the L-shaped plate 113 drives the second rotating plate 121 to rotate upwards. After the second rotating plate 121 rotates, it is convenient for the flocs collected inside the pushing plate 111 to be discharged. The movement of the square plate 114 will contact the sealing rubber 122. After being squeezed, the sealing rubber 122 deforms, so that the square plate 114 is sealed with the static box 1, preventing water from flowing out and being wasted when discharging the flocs, and ensuring the treatment effect of water quality treatment. The movement of the square plate 114 drives the positioning block 124 to move. The movement of the positioning block 124 will contact the triangular block 126 and drive the triangular block 126 to rotate upwards. The rotation of the triangular block 126 drives the rotating rod 125 to rotate. After the triangular block 126 no longer contacts the positioning block 124, the first torsion spring resets to drive the rotating rod 125 to rotate downwards. The rotation of the rotating rod 125 drives the triangular block 126 to rotate downwards and limits the positioning block 124, further improving the sealing effect of the device.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
