Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a sewage recycling and reuse treatment device and method. Background Art

[0002] Sewage refers to water containing various pollutants produced in daily life and industrial production processes. Sewage recycling and reuse refers to the process of directing industrial, agricultural and domestic sewage into a predetermined purification system, and using physical, chemical or biological methods to remove pollutants such as branches or plastics in the sewage so that it meets the standards for reuse.

[0003] When physical methods are used to treat domestic sewage, a screen mesh is usually used to intercept pollutants, causing the pollutants to be deposited in the screen mesh. The intercepted pollutants are then transported to a pollutant collection tank through a screw conveyor device, and the pollutants are dehydrated at the same time, thereby preventing the pollutants from causing secondary pollution to the environment and facilitating subsequent treatment of the pollutants.

[0004] The following problems exist in the current recycling and reuse of domestic sewage: 1. Since sewage may contain long rod-shaped pollutants such as branches or large block-shaped pollutants such as plastics, excessive accumulation of long rod-shaped pollutants or large block-shaped pollutants may easily lead to reduced sewage recovery efficiency and even cause blockage; 2. When pollutants are transported, the pollutants may accumulate together, and then when the pollutants are dehydrated, the water inside the accumulated pollutants may not be discharged, resulting in the inability to completely dehydrate the pollutants, so that the pollutants that are not completely dehydrated may cause secondary pollution to the environment.

DETAILED DESCRIPTION

[0039] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0040] See also Figure 1 and Figure 2 A sewage recycling and reuse treatment device comprises a grille filter unit 1 with its right end tilted downward, a screw conveying unit 2 is installed on the grille filter unit 1, the screw conveying unit 2 comprises a rotating shaft 21, a spiral blade 22 is fixedly installed on the outer side of the rotating shaft 21, a plurality of spirally arranged extrusion units 3 are installed in the middle of the rotating shaft 21, a shearing unit 4 and a crushing unit 5 are installed on the rotating shaft 21 and on the right side of the spiral blade 22 from left to right in sequence, and the extrusion unit 3 is used to dehydrate pollutants.

[0041] It should be noted that the grid filter unit 1 and the spiral conveying unit 2 in the present invention both adopt the existing technology, wherein the grid filter unit 1 includes a grid plate with an arc structure, and the right end of the grid plate is arranged to be tilted downward. The grid plate can intercept pollutants, thereby removing pollutants in sewage and realizing sewage recovery. A plurality of L-shaped brackets are fixedly installed on the front and rear sides of the grid plate, and a water inlet cylinder is fixedly installed on the right end of the grid plate. The spiral conveying unit 2 includes a conveying cylinder fixedly installed on the left end of the grid plate, and a discharge port is opened on the lower left end of the conveying cylinder. The left end of the rotating shaft 21 is fixedly connected to a motor fixedly installed on the left inner wall of the conveying cylinder. The motor is started to drive the rotating shaft 21 to rotate, so that the rotating shaft 21 drives the spiral blades 22 to transport the pollutants from right to left, and when the pollutants move to the corresponding position of the discharge port, the pollutants can fall from the discharge port.

[0042] The present invention is used for recycling and reusing sewage. The present invention can shear longer rod-shaped pollutants and crush larger block-shaped pollutants, thereby ensuring the efficiency of sewage recycling and preventing pollutant accumulation and blockage. The present invention can also completely dehydrate the pollutants to prevent residual water in the pollutants from causing secondary pollution to the environment.

[0043] Specifically, the sewage is passed into the water inlet cylinder of the grid filter unit 1, and the rotating shaft 21 of the spiral conveying unit 2 is started to drive the spiral blade 22 to rotate forward, so that the spiral conveying unit 2 can convey the sewage and pollutants into the grid filter unit 1. When the sewage flows to the corresponding positions of the shearing unit 4 and the crushing unit 5, the spiral conveying unit 2 can drive the shearing unit 4 to shear the longer rod-shaped pollutants, and at the same time, the spiral conveying unit 2 can drive the crushing unit 5 to crush the larger block pollutants and some longer rod-shaped pollutants. The treated pollutants continue to move to the left under the action of the spiral blade 22, and the grid filter unit 1 can intercept the pollutants, thereby removing the pollutants in the sewage and realizing the recovery of the sewage. When the pollutants move to the corresponding position of the extrusion unit 3, the extrusion unit 3 can extrude and dehydrate the pollutants, and the extrusion unit 3 can flatten the pollutants front and back, thereby ensuring that the residual water in the pollutants is completely squeezed out, and the dehydrated pollutants move to the corresponding position of the discharge port when the spiral blade 22 moves, so that the pollutants can be moved out of the conveying cylinder, and finally the pollutants are collected manually.

[0044] See also Figure 2 , Figure 3 , Figure 5 and Figure 6An annular plate 23 is fixedly sleeved on the outside of the rotating shaft 21 and located on the right side of the spiral blade 22. The outside of the annular plate 23 is fixedly connected to the grille filter unit 1 through a plurality of matching plates 24. A fixed shaft 25 is rotatably installed in the rotating shaft 21. The right end of the fixed shaft 25 passes through the right end of the rotating shaft 21 and is fixedly connected to the grille filter unit 1 through a plurality of fixing rods; wherein the matching plate 24 is fixedly connected to the water inlet cylinder of the grille filter unit 1; the shearing unit 4 includes a connecting sleeve 41 rotatably sleeved on the outside of the rotating shaft 21 and located on the left side of the annular plate 23, a plurality of arc springs 42 are connected between the connecting sleeve 41 and the rotating shaft 21, a plurality of circumferentially evenly arranged shear plates 43 are fixedly installed on the outside of the connecting sleeve 41, and a pressurizing mechanism 26 for increasing the shear force of the shear plates 43 is installed on the rotating shaft 21.

[0045] The shearing unit 4 is used to shear longer rod-shaped pollutants such as tree branches; specifically, when the rotating shaft 21 rotates, the rotating shaft 21 drives the shearing plate 43 to rotate relative to the matching plate 24 through the connecting sleeve 41. When longer rod-shaped pollutants such as tree branches in the sewage flow into the corresponding positions of the shearing plate 43 and the matching plate 24, the shearing plate 43 can cooperate with the matching plate 24 to shear the longer rod-shaped pollutants, and the shearing plate 43 rotates in the direction opposite to the rotation direction of the rotating shaft 21 under the blocking effect of the pollutants and compresses the arc spring 42 through the connecting sleeve 41, so that the shearing plate 43 can continue to cooperate with the matching plate 24 to shear the longer rod-shaped pollutants. At the same time, the pressurizing mechanism 26 can increase the shearing force of the shearing plate 43 on the rod-shaped pollutants to ensure thorough shearing of the pollutants. After the longer rod-shaped pollutants are sheared, the pollutants no longer block the shearing plate 43, and the shearing plate 43 is restored to its initial position relative to the rotating shaft 21 under the action of the arc spring 42.

[0046] See also Figure 5 , Figure 7 and Figure 8, a plurality of circumferentially evenly arranged matching rods 44 are fixedly installed on the left side of the connecting sleeve 41, and the pressurizing mechanism 26 includes a plurality of pressurizing plates 261 slidably installed on the rotating shaft 21 and corresponding to the installation positions of the matching rods 44 one by one, and the end of the pressurizing plate 261 which is away from the center of the rotating shaft 21 and has the same rotation direction as the rotating shaft 21 is set as an inclined surface, and a top extension spring 262 is connected between the pressurizing plate 261 and the rotating shaft 21, and an impact spring rod 263 is contacted and set on the side of the pressurizing plate 261 close to the center of the rotating shaft 21, and the impact spring rod 263 is slidably connected to the rotating shaft 21; A clearance groove 211 is opened in the rotating shaft 21 at a position corresponding to the connecting sleeve 41, and a circular ring 27 is provided on the outside of the fixed shaft 25 and in the fixed sleeve in the clearance groove 211. A plurality of circumferentially evenly arranged arc-shaped matching blocks 28 are fixedly installed on the left end of the circular ring 27. The matching block 28 is close to the fixed shaft 25 and the end opposite to the rotation direction of the rotating shaft 21 is set as an inclined surface. The end of the impact spring rod 263 away from the pressure plate 261 slides through the clearance groove 211 and is fixedly installed with a pressure rod 264. The pressure rod 264 is used to cooperate with the inclined surface of the matching block 28 to compress the impact spring rod 263.

[0047] The pressurizing mechanism 26 is used to increase the shearing force of the shearing plate 43; specifically, when the shearing plate 43 moves in the direction opposite to the rotation direction of the rotating shaft 21 under the blocking effect of the rod-shaped contaminants, the shearing plate 43 drives the matching rod 44 to move in the direction opposite to the rotation direction of the rotating shaft 21 through the connecting sleeve 41, so that the matching rod 44 and the inclined surface of the pressurizing plate 261 cooperate to drive the pressurizing plate 261 to move toward the center of the rotating shaft 21 and compress the extension spring 262. At the same time, the pressurizing plate 261 can compress the impact spring rod 263, and the rotating shaft 21 drives the impact spring rod 263 to rotate continuously. When the impact spring rod 263 drives the pressure rod 264 to rotate to the corresponding position of the inclined surface of the matching block 28, the matching block 28 is pressed. The inclined surface and the pressure rod 264 cooperate to quickly compress the impact spring rod 263, so that the impact spring rod 263 and the pressure plate 261 are separated and move in the direction away from the pressure plate 261. When the pressure rod 264 and the matching block 28 are separated, the impact spring rod 263 is elastically ejected in the direction away from the center of the rotating shaft 21 and impacts the pressure plate 261, so that the inclined surface of the pressure plate 261 can apply a force in the same direction of rotation of the rotating shaft 21 to the connecting sleeve 41 through the matching rod 44, thereby increasing the shear force of the shear plate 43 on the pollutants. When the shear plate 43 returns to its initial position relative to the rotating shaft 21, the pressure plate 261 returns to its initial position under the action of the extension spring 262.

[0048] See also Figure 2 , Figure 5 and Figure 12-14The crushing unit 5 includes a plurality of crushing plates 51 hinged on the outside of the annular plate 23 and arranged at intervals with the matching plates 24. The left end of the crushing plate 51 is set as a pointed structure. A matching mechanism 52 for matching the crushing plates 51 and the matching plates 24 to crush pollutants is installed between the right ends of the plurality of crushing plates 51 and the rotating shaft 21. Cleaning mechanisms 53 for cleaning pollutants on the crushing plates 51 are installed at positions corresponding to the crushing plates 51 on the matching mechanisms 52.

[0049] The crushing unit 5 is used to crush larger block pollutants and some longer rod-shaped pollutants in sewage; specifically, when the rotating shaft 21 rotates, the rotating shaft 21 can cooperate with the matching mechanism 52 to drive the crushing plate 51 to rotate to the right first based on the hinge between it and the annular plate 23, and at the same time, the cleaning mechanism 53 can clean the pollutants on the right side of the crushing plate 51 to prevent the crushing plate 51 from driving the pollutants to rotate to the right, so that the two adjacent matching plates 24 can block the larger block pollutants and some longer rod-shaped pollutants, and then the matching mechanism 52 can drive the crushing plate 51 to impact quickly to the left, and the left end of the crushing plate 51 is set to a pointed structure, so that the crushing plate 51 can crush the pollutants blocked by the two adjacent matching plates 24.

[0050] See also Figure 5 , Fig. 9 , Fig.10 and Figure 12-14 The matching mechanism 52 includes a matching spring rod 521 slidably mounted on the right end of the rotating shaft 21, and the matching spring rod 521 is slidably sleeved on the outside of the fixed shaft 25, and a synchronous sleeve 522 is rotatably sleeved on the outside of the matching spring rod 521, and an L-shaped plate 523 is fixedly mounted on the position of the outer side of the synchronous sleeve 522 corresponding to the crushing plate 51, and one end of the L-shaped plate 523 connected to the synchronous sleeve 522 is set as an elastic telescopic structure, and the end of the left side of the transverse section of the L-shaped plate 523 close to the matching spring rod 521 is hinged to the corresponding crushing plate 51 through a transmission plate 524; A lever 525 is fixedly installed on the matching spring rod 521 and on the right side of the synchronous sleeve 522. A plurality of circumferentially evenly arranged arc-shaped lever blocks 11 and pressure blocks 12 are fixedly installed at the position corresponding to the lever 525 in the grille filter unit 1, and the circumferentially evenly arranged arc-shaped lever blocks 11 and the pressure blocks 12 are arranged at intervals. The right end of the oscillating block 11 and the side opposite to the rotation direction of the rotating shaft 21 are both provided with an inclined surface for driving the lever 525 to move to the right, and the left end of the pressure block 12 and the side opposite to the rotation direction of the rotating shaft 21 are both provided with an inclined surface for driving the lever 525 to move to the left.

[0051] The matching mechanism 52 is used to make the crushing plate 51 and the matching plate 24 cooperate to crush the pollutants; specifically, when the rotating shaft 21 rotates forward, the rotating shaft 21 drives the matching spring rod 521 to rotate forward synchronously, so that the matching spring rod 521 drives the lever 525 to rotate forward, and the lever 525 can first rotate to the corresponding position of the toggle block 11, so that the inclined surface of the toggle block 11 and the lever 525 cooperate to drive the matching spring rod 521 to move to the right, so that the matching spring rod 521 drives the crushing plate 51 to rotate to the right with the hinge between it and the annular plate 23 as a reference through the L-shaped plate 523. When the lever 525 and the toggle block 11 are separated, the matching spring rod 521 quickly returns to the initial position under its elastic action, and then the matching spring rod 521 drives the crushing plate 51 to quickly return to the initial position through the L-shaped plate 523, so that the crushing plate 51 quickly impacts to the left and crushes the pollutants blocked by two adjacent matching plates 24.

[0052] When the lever 525 moves to the corresponding position of the pressure block 12, the inclined surface of the pressure block 12 can cooperate with the lever 525 to drive the matching spring rod 521 to move to the left, and then the matching spring rod 521 drives the crushing plate 51 to rotate left based on the hinge between it and the annular plate 23 through the L-shaped plate 523, and the lever block 11 and the pressure block 12 are arranged at intervals and are each provided with multiple pieces, so that the crushing plate 51 can continue to impact and crush the pollutants blocked by two adjacent matching plates 24, and then continue to push to the left, and then, after impacting longer rod-shaped pollutants with a certain toughness such as tree branches, the rod-shaped pollutants may not be completely crushed due to their toughness, and at this time, the crushing plate 51 can continue to push the rod-shaped pollutants with a certain toughness to the left, so that the pollutants can be completely crushed and moved to the left side of the matching plate 24, thereby ensuring the complete crushing of the pollutants.

[0053] See also Figure 10-Figure 14 The cleaning mechanism 53 includes a clamping plate 531 slidably installed on the left side of the transverse section of the L-shaped plate 523, away from one end of the matching spring rod 521. A clamping spring 532 is connected between the clamping plate 531 and the L-shaped plate 523. A cleaning plate 533 is fixedly installed on the end of the clamping plate 531 away from the L-shaped plate 523. The left end of the cleaning plate 533 is in contact with the right side of the crushing plate 51 and is inclined in the direction away from the rotating shaft 21.

[0054] The cleaning mechanism 53 is used to clean the pollutants on the crushing plate 51; specifically, when the crushing plate 51 rotates to the right based on the hinge between it and the annular plate 23, the crushing plate 51 can cooperate with the cleaning plate 533 to drive the clamping plate 531 to move to the right and compress the clamping spring 532, and since the cleaning plate 533 is in contact with the right side of the crushing plate 51, while the crushing plate 51 rotates, the cleaning plate 533 can move along the right side of the crushing plate 51 and scrape the pollutants on the right side of the cleaning plate 533 away from the crushing plate 51, thereby cleaning the pollutants on the right side of the crushing plate 51, and preventing the crushing plate 51 from driving the pollutants on its right side to rotate, resulting in some pollutants being unable to be crushed.

[0055] See also Figure 2-Figure 4 The squeezing unit 3 includes a downward pressing spring rod 31 slidably mounted on the rotating shaft 21, and one end of the downward pressing spring rod 31 close to the center of the rotating shaft 21 is set to an arc structure, and one end of the downward pressing spring rod 31 away from the center of the rotating shaft 21 is fixedly mounted with a connecting plate 32, and one end of the connecting plate 32 away from the rotating shaft 21 is slidably mounted with a square spring rod 34, and one end of the square spring rod 34 away from the connecting plate 32 is fixedly mounted with an arc-structured squeezing plate 35, and the left and right ends of the squeezing plate 35 are both slidably mounted with a plurality of circumferentially uniformly arranged close rods 33 through connecting springs 36; a circular groove is opened in the middle of the rotating shaft 21, The lower end of the fixed shaft 25 and the position corresponding to the downward pressure spring rod 31 are fixedly installed with a conical block 251 for driving the downward pressure spring rod 31 to move away from the center of the rotating shaft 21, and a plurality of arc blocks 252 evenly arranged in the circumferential direction are fixedly installed on the lower side of the conical block 251; the end of the connecting plate 32 away from the rotating shaft 21 is fixedly installed with two square plates 321 symmetrically arranged on the left and right, and the opposite sides of the two square plates 321 are provided with corrugated grooves 322; the telescopic end of the square spring rod 34 is fixedly installed with two round rods 341 symmetrically arranged on the left and right, and the round rods 341 are slidably installed in the corrugated grooves 322.

[0056] The squeezing unit 3 is used to squeeze and dehydrate the pollutants; specifically, when the rotating shaft 21 rotates, the rotating shaft 21 drives the downward pressure spring rod 31 to rotate synchronously. When the downward pressure spring rod 31 rotates to the corresponding position of the conical block 251, the downward pressure spring rod 31 moves in the direction away from the center of the rotating shaft 21 under the action of the conical block 251, so that the downward pressure spring rod 31 finally drives the squeezing plate 35 to fit into the grid plate of the grid filter unit 1 through the connecting plate 32, and at this time the square spring rod 34 can be compressed, so that the squeezing plate 35 can squeeze the pollutants in the direction close to the grid plate, thereby realizing squeezing and dehydrating the pollutants. When the downward pressure spring rod 31 rotates to the corresponding position of the arc block 252, the downward pressure spring rod 31 can move again in the direction away from the center of the rotating shaft 21 under the action of the arc block 252, so that the downward pressure spring rod 31 compresses the square spring rod 34 through the connecting plate 32, thereby increasing the squeezing force of the squeezing plate 35 on the pollutants, ensuring that the pollutants are completely dehydrated.

[0057] When the telescopic end of the square spring rod 34 is compressed, the telescopic end of the square spring rod 34 moves upward relative to the square plate 321, so that the square spring rod 34 drives the round rod 341 to move upward relative to the square plate 321, so that the round rod 341 can drive the square spring rod 34 to move forward and backward under the action of the corrugated groove 322, and then the square spring rod 34 drives the extrusion plate 35 to move forward and backward, so that the extrusion plate 35 can flatten the pollutants, further ensuring that the pollutants can be completely dehydrated. At the same time, when the extrusion plate 35 moves toward the direction close to the grid plate, the extrusion plate 35 drives the clamping rod 33 to move synchronously, and the clamping rod 33 is always clamped on the spiral blade 22 under the action of the connecting spring 36, so that the clamping rod 33 can clean the pollutants adhering to the spiral blade 22, and no manual cleaning is required, thereby further increasing the efficiency of sewage recovery.

[0058] In addition, the present invention also provides a sewage recycling and reuse treatment method, which is completed by using a sewage recycling and reuse treatment device. The specific steps are as follows: S1, water inlet: sewage is introduced into the water inlet cylinder of the grid filter unit 1.

[0059] S2. Pollutant treatment: Control the rotation of the rotating shaft 21. The rotating shaft 21 drives the shear plate 43 to rotate relative to the matching plate 24 through the connecting sleeve 41. When the longer rod-shaped pollutants in the sewage flow into the corresponding positions of the shear plate 43 and the matching plate 24, the shear plate 43 can cooperate with the matching plate 24 to shear the rod-shaped pollutants. When shearing the pollutants, the shear plate 43 rotates in the direction opposite to the rotation direction of the rotating shaft 21 under the blocking effect of the pollutants, so that the matching rod 44 and the inclined surface of the pressure plate 261 drive the pressure plate 261 to move toward the center of the rotating shaft 21. At the same time, the matching block 28 and the pressure rod 264 cooperate to drive the impact spring rod 263 to impact the pressure plate 261, so that the inclined surface of the pressure plate 261 can apply a force in the same direction of rotation of the rotating shaft 21 to the connecting sleeve 41 through the matching rod 44, thereby increasing the shear force of the shear plate 43 on the rod-shaped pollutants.

[0060] At the same time, the two adjacent matching plates 24 can block larger block-shaped pollutants and some longer rod-shaped pollutants, and the lever 525 can be sequentially acted upon by the toggle block 11 and the pressure block 12, and the lever 525 can finally drive the crushing plate 51 to rotate rightward based on the hinge between the lever 525 and the annular plate 23, and then the crushing plate 51 quickly returns to the initial position, so that the crushing plate 51 quickly impacts to the left and crushes the pollutants blocked by the two adjacent matching plates 24, and then the crushing plate 51 continues to push the tool leftward. The rod-shaped pollutants have a certain toughness, so that the rod-shaped pollutants can be completely crushed and moved to the left side of the matching plate 24, thereby ensuring the complete crushing of the pollutants, and when the crushing plate 51 rotates to the right based on the hinge between it and the annular plate 23, the cleaning plate 533 can move along the right side of the crushing plate 51 and scrape the pollutants on the right side of the cleaning plate 533 away from the crushing plate 51, thereby cleaning the pollutants on the right side of the crushing plate 51, thereby preventing the crushing plate 51 from driving the pollutants on its right side to rotate, resulting in some pollutants being unable to be crushed.

[0061] S3. Wastewater recovery: The grid plate of the grid filter unit 1 can intercept pollutants, thereby removing pollutants in the sewage and realizing the recycling and reuse of the sewage. When the rotating shaft 21 rotates, the rotating shaft 21 drives the downward pressure spring rod 31 to rotate synchronously. When the downward pressure spring rod 31 rotates to the corresponding position of the conical block 251, the downward pressure spring rod 31 drives the extrusion plate 35 to move away from the center of the rotating shaft 21 under the action of the conical block 251, so that the extrusion plate 35 dehydrates the pollutants. At the same time, the downward pressure spring rod 31 can move away from the center of the rotating shaft 21 again under the action of the arc block 252, so that the downward pressure spring rod 31 compresses the square spring rod 34 through the connecting plate 32, thereby increasing the extrusion force of the extrusion plate 35 on the pollutants, ensuring that the pollutants are completely dehydrated.

[0062] When the telescopic end of the square spring rod 34 is compressed, the round rod 341 can drive the square spring rod 34 to move forward and backward under the action of the corrugated groove 322, and then the square spring rod 34 drives the extrusion plate 35 to move forward and backward, so that the extrusion plate 35 can flatten the pollutants, further ensuring that the pollutants can be completely dehydrated. At the same time, the sticking rod 33 can clean the pollutants adhering to the spiral blade 22, further increasing the efficiency of sewage recovery.

[0063] S4, pollutant collection: the dehydrated pollutants are moved to the corresponding position of the discharge port by the spiral blade 22, so that the pollutants can be moved out of the conveying cylinder, and finally the pollutants are collected manually.

[0064] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
