Description

Technical Field

[0001] The invention relates to the technical field of industrial sludge wastewater treatment, in particular to a wastewater separation and purification device in industrial sludge. Background Art

[0002] Industrial sludge is sludge produced by industrial wastewater treatment stations. It is mainly composed of inorganic and organic matter, and contains chemical components in production wastewater. It usually belongs to the category of hazardous waste. Industrial sludge not only contains conventional components such as water, ash, volatile substances, etc., but may also contain heavy metals, toxic substances, pathogens and other harmful substances.

[0003] When industrial sludge is separated from wastewater, a centrifuge is generally used to separate it. However, there is not only obvious wastewater in the sludge, but also a part of combined water and adsorbed water. Centrifugal separation cannot treat the combined water and adsorbed water, resulting in the inner wall of the sludge still being relatively moist after separation. Generally, the combined water and adsorbed water in the sludge usually need to be treated with chemical reagents. This treatment method is costly, and improvements need to be made to this problem. Summary of the invention

[0004] The object of the present invention is to provide a wastewater separation and purification device in industrial sludge to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a wastewater separation and purification device in industrial sludge, comprising a water collecting tank, and also comprising a separation mechanism, a mounting mechanism, an extrusion mechanism and a splash-proof cover.

[0009] According to the above technical scheme, the extrusion mechanism includes motor three, a rotating shaft, a rotating gear, an adjustment rack, a connecting plate, a telescopic rod, a translation plate, an extrusion frame, an extrusion roller, a shovel plate, a rotating cylinder, a spring and a mud shoveling ring. The rotating cylinder is fixedly connected to the bottom of the drive box, the motor three is fixedly connected to the bottom of the drive box, the motor three has an output shaft, the rotating shaft is fixedly connected to the bottom of the output shaft of the motor three, the rotating gear is fixedly connected to the bottom of the rotating shaft, the adjustment rack is meshed with the back of the rotating gear, the connecting plate is fixedly connected to the left side of the adjustment rack, the telescopic rod is fixedly connected to the left side of the connecting plate, the translation plate is fixedly connected to the left end of the telescopic rod, the extrusion frame is fixedly connected to the left side of the translation plate, the extrusion roller is rotatably connected to the middle part of the extrusion frame, the shovel plate is fixedly connected to the front and rear ends of the left side of the translation plate, the spring is fixedly connected to the left side of the rotating cylinder, and the mud shoveling ring is fixedly connected to the left end of the spring.

[0010] According to the above technical solution, the output shaft of the motor 1 penetrates the top inner wall of the waterproof box and the bottom of the fixed plate and extends above the fixed plate to be fixedly connected to the ultra-dense filter material, so that the motor 1 can drive the ultra-dense filter material to rotate.

[0011] According to the above technical solution, the splash-proof cover is arranged on the inner side of the mounting frame and is slidably connected to the inner side of the mounting frame. The output shaft of the second motor passes through the bottom of the mounting frame, the middle of the splash-proof cover and extends to the bottom of the splash-proof cover and is fixedly connected to the rotating plate, so that the second motor can drive the rotating plate to rotate.

[0012] According to the above technical solution, the output shaft of the motor 3 passes through the bottom inner wall of the driving box and the top of the rotating cylinder and extends into the rotating cylinder to be fixedly connected to the rotating shaft, so that the motor 3 drives the rotating shaft to rotate.

[0013] According to the above technical solution, a circular groove is opened on the left side of the rotating cylinder to accommodate the movement of the telescopic rod, and the spring is arranged on the upper and lower sides of the circular groove. The inner ring of the mud shoveling ring is in contact with the outer wall of the telescopic rod, so that the mud shoveling ring can shovel away the sludge adhered to the outer wall of the telescopic rod.

[0014] According to the above technical solution, the shovel plate is in contact with the squeezing roller on one side close to the squeezing roller, so that the shovel plate can shovel away the sludge adhered to the squeezing roller. A drain outlet is provided at the bottom right of the water collecting tank, and the rotating cylinder is rotatably connected to the bottom of the separation screen barrel.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention inserts the mounting frame into the card block, at which time the mounting frame and the motor three are relatively fixed, and then the motor two is controlled to work, so that the rotating plate at the lower side of the motor two coincides with the position of the driven rotating block, and at this time the rotating plate at the lower side of the motor two is inserted into the driven rotating block, so that when the motor two is working, the driven rotating block at the lower side of the rotating plate is controlled to rotate, and the driving box is synchronously driven to rotate, and at the same time the mounting frame, the motor two, and the rotating plate can be removed, which is convenient for subsequent cleaning;

[0016] When the sludge needs to be separated from wastewater, the sludge is poured into the separation screen barrel through the top of the separation screen barrel, and then the motor three is controlled to work. When the motor three is working, the rotating shaft and the rotating gear are driven to rotate. When the rotating gear rotates, the rotating gear can drive the adjusting rack to move, so that the connecting plate on the adjusting rack pushes the telescopic rod to move. At the same time, when the telescopic rod moves, the squeezing roller on the left side of the telescopic rod contacts the sludge. At the same time, the motor two is controlled to work, so that the motor two drives the lower drive box to rotate, and the telescopic rod is further rotated, so that the sludge can be rotated and spread on the inner wall of the separation screen barrel to avoid sludge stacking, which reduces the efficiency of subsequent centrifugal separation.

[0017] After the sludge is spread on the inner wall of the separation screen barrel, the motor three is controlled to work, the squeezing roller is moved close to the outside of the rotating cylinder, and then the splash cover is slid to close the top of the separation screen barrel. Then the motor one in the waterproof box is controlled to work, so that the motor one drives the separation screen barrel to rotate. When the separation screen barrel rotates, the internal sludge is centrifugally separated, and the centrifugal force throws out a large amount of water in the sludge;

[0018] After centrifugal separation, there is combined water and adsorbed water in the sludge, which are difficult to separate. When the separation screen barrel rotates, the motor three is controlled to work, so that the motor three rotates and drives the rotating gear to rotate, so that the rotating gear pushes the squeezing roller to slowly contact the sludge by adjusting the rack and the connecting plate, and when the separation screen barrel rotates, the sludge can be squeezed according to the contact distance between the squeezing roller and the sludge, so that part of the combined water and adsorbed water in the sludge can be squeezed out, reducing the cost of sludge treatment and making the device more efficient in wastewater separation. When the squeezing roller contacts the sludge, the shovel plate can shovel the sludge adhered to the outside of the squeezing roller to ensure that the squeezing roller can continue to rotate and work, and prevent the squeezing roller from being unusable due to sludge accumulation;

[0019] After the wastewater separation is completed, the motor is controlled to rotate in the opposite direction to move the squeezing roller toward the outer wall of the rotating cylinder. When the telescopic rod moves, the sludge adhered to the outside of the telescopic rod squeezes the shoveling ring. At this time, the sludge on the outside of the telescopic rod can be removed. At the same time, the spring is in a compressed state. When the sludge on the telescopic rod is removed, the shoveling ring has no resistance from the sludge, so the spring elasticity is restored, and the spring drives the shoveling ring to move to the left on the telescopic rod. At the same time, the shoveling ring shakes off the sludge adhered to the surface, so that the device can be self-cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The output shaft of the motor three 601 passes through the bottom inner wall of the driving box 506 and the top of the rotating cylinder 611 and extends into the rotating cylinder 611 and is fixedly connected to the rotating shaft 602, so that the motor three 601 drives the rotating shaft 602 to rotate.

[0043] A circular groove is provided on the left side of the rotating cylinder 611 to accommodate the movement of the telescopic rod 606. The spring 612 is arranged on the upper and lower sides of the circular groove. The inner circle of the mud shoveling ring 613 fits the outer wall of the telescopic rod 606, so that the mud shoveling ring 613 can shovel away the mud adhered to the outer wall of the telescopic rod 606.

[0044] The shovel plate 610 is in contact with the squeezing roller 609 on one side thereof, so that the shovel plate 610 can remove the sludge adhering to the squeezing roller 609 .

[0045] When the sludge needs to be separated from the wastewater, the sludge is poured into the separation screen barrel 404 through the top of the separation screen barrel 404, and then the motor three 601 is controlled to work. When the motor three 601 is working, it drives the rotating shaft 602 and the rotating gear 603 to rotate. When the rotating gear 603 rotates, the rotating gear 603 can drive the adjusting rack 604 to move, so that the connecting plate 605 on the adjusting rack 604 pushes the telescopic rod 606 to move, and at the same time, when the telescopic rod 606 moves, the squeezing roller 609 on the left side of the telescopic rod 606 contacts the sludge.

[0046] After centrifugal separation, there is combined water and adsorbed water in the sludge, which are difficult to separate. When the separation screen barrel 404 rotates, the motor three 601 is controlled to work, so that the motor three 601 drives the rotating gear 603 to rotate when it rotates, so that the rotating gear 603 pushes the squeezing roller 609 to slowly contact the sludge by adjusting the rack 604 and the connecting plate 605, and when the separation screen barrel 404 rotates, the sludge can be squeezed according to the contact distance between the squeezing roller 609 and the sludge, so that part of the combined water and adsorbed water in the sludge are squeezed out, so that the device is more efficient in wastewater separation. When the squeezing roller 609 contacts the sludge, the shovel plate 610 can shovel away the sludge adhered to the outside of the squeezing roller 609, to ensure that the squeezing roller 609 can continue to rotate and work, while preventing the squeezing roller 609 from being unusable due to sludge accumulation.

[0047] After the wastewater separation is completed, the control motor 3 601 rotates in the opposite direction, so that the squeezing roller 609 moves toward the outer wall of the rotating cylinder 611. When the telescopic rod 606 moves, the sludge adhered to the outside of the telescopic rod 606 squeezes the shoveling ring 613. At this time, the shoveling ring 613 can shovel the sludge on the outside of the telescopic rod 606. At the same time, the spring 612 is in a compressed state. When the sludge on the telescopic rod 606 is removed, the shoveling ring 613 has no resistance from the sludge, so that the spring 612 recovers its elasticity, so that the spring 612 drives the shoveling ring 613 to move to the left on the telescopic rod 606. At the same time, the shoveling ring 613 shakes off the sludge adhered to the surface, so that the device can be self-cleaning.
