Description

Technical Field

[0001] The present invention relates to the technical field of sludge conditioning agent preparation, in particular to an environmentally friendly sludge conditioning agent preparation device and process. Background Art

[0002] Sludge conditioner is a chemical agent that can change the surface structure of sludge, reduce the solid surface load of sludge, reduce the specific surface area of ​​sludge, and destroy the bacterial structure. Among them, polyacrylamide products are one of the commonly used sludge conditioners; polyacrylamide production uses acrylamide aqueous solution as raw material, and undergoes polymerization reaction under the action of initiator. After the reaction is completed, the polyacrylamide blocks generated are cut, granulated, dried, and crushed to finally produce polyacrylamide products.

[0003] In the existing technology, raw materials such as acrylamide aqueous solution are usually directly added to the reactor for polymerization. During the polymerization reaction of the raw materials, the lumpy polyacrylamide will adhere to the inner wall of the reactor, resulting in a waste of raw materials and reduced utilization rate. Secondly, when the initiator is added to the reactor, it will cause local raw materials to react faster, while the rest of the raw materials will not react, resulting in uneven polymerization reaction.

[0048] See also Figures 1-21, this embodiment provides a technical solution: an environmentally friendly sludge conditioning agent preparation device, including a reactor 1, a rotating shaft 2 is rotatably connected to the middle part of the reactor 1, and two stirring blades 3 are provided on both sides of the rotating shaft 2 through a material removal mechanism. The material removal mechanism is used to drive the two stirring blades 3 to scrape the inner wall of the reactor 1 when the reaction is completed, and discharge the scraped material from the discharge port at the bottom end of the reactor 1. A mounting plate 4 is fixedly installed on the outer side of the rotating shaft 2, and holes are evenly opened in the middle of the mounting plate 4. A filling mechanism is provided on the top of the mounting plate 4. The filling mechanism is used to evenly and repeatedly add initiator into the holes of the mounting plate 4 when the rotating shaft 2 rotates. The top of the reactor 1 is provided with a first filling port 5 and a second filling port 6;

[0049] The material removal mechanism includes mounting rods 7 fixedly mounted on both ends of the rotating shaft 2, and the ends of the two mounting rods 7 away from each other are slidably connected to telescopic rods 8 by tension springs. The ends of the two telescopic rods 8 away from each other are fixedly connected to the two stirring blades 3 respectively. The top of the stirring blade 3 is provided with a pushing mechanism, which is used to push the stirring blade 3 to fit into the inner wall of the reactor 1. A lifting groove 9 is provided in the middle of the rotating shaft 2, and a lifting block 10 is provided on the inner side of the lifting groove 9 through a lifting mechanism. The lifting mechanism is used to drive the lifting block 10 to reciprocate up and down when the rotating shaft 2 rotates. The front and rear ends of the lifting block 10 are slidably connected to slide rods 11, and the ends of the slide rods 11 away from the lifting block 10 are provided with scrapers 12 through a flipping mechanism. The scrapers 12 fit into the side walls of the stirring blade 3, and the flipping mechanism is used to keep the scrapers 12 in a horizontal state when they move downward, and to tilt the scrapers 12 when they move upward.

[0050] During operation, the raw materials are first added into the reactor 1, and the reactor 1 is started to drive the rotating shaft 2 to rotate. The rotating shaft 2 rotates and drives the stirring blade 3 to stir the raw materials through the mounting rod 7 and the telescopic rod 8. While the rotating shaft 2 rotates, the filling mechanism evenly fills the initiator into the holes of the mounting plate 4. Every time the rotating shaft 2 rotates one circle, the initiator will be added once, thereby achieving a small amount of uniform addition of initiator to the raw materials, avoiding the situation where too much initiator is added at one time, causing some raw materials to over-react while some raw materials cannot react, reducing the workload of the staff, providing convenience for the addition of initiator, and solving the problem that the existing environmentally friendly sludge conditioning agent preparation device does not have a uniform feeding function;

[0051] When the processing of the reactor 1 is completed, the bottom of the reactor 1 is opened for discharge. At this time, the pushing mechanism pushes the stirring blade 3 to fit the inner wall of the reactor 1. The rotating shaft 2 rotates and drives the stirring blade 3 to scrape off the rubber blocks adhered to the inner wall of the reactor 1, thereby improving the utilization rate of the raw materials and reducing waste. It is no longer necessary for the staff to manually scrape and clean the inner wall of the reactor 1 after the processing is completed, which greatly reduces the workload of the staff and provides convenience for the cleaning work of the reactor 1.

[0052] When the scraper 12 moves upward, the scraper 12 will not scrape the material on the surface of the stirring blade 3 upward, which provides convenience for the use of the stirring blade 3. By setting the scraper 12, the scraper 12 continues to push the material downward under the drive of the lifting mechanism, which greatly speeds up the discharge of the material in the reactor 1, provides convenience for the use of the reactor 1, and solves the problem that the existing environmentally friendly sludge conditioning agent preparation device does not have the function of removing the material from the inner wall of the reactor 1.

[0053] As a further solution of this embodiment, the pushing mechanism includes a pushing ring 13 slidably connected to the inner wall of the reactor 1, and a pushing block 14 is fixedly installed on the top of the stirring blade 3. The bottom inclined surface of the pushing ring 13 is in contact with the top of the pushing block 14. A push rod is fixedly installed on the top of the left end of the pushing ring 13. A screw 16 is rotatably connected to the top of the left end of the reactor 1. The bottom end of the screw 16 passes through the push rod and is threadedly connected to it.

[0054] During operation, when the processing of the reactor 1 is completed, it is only necessary to rotate the screw 16. The rotation of the screw 16 drives the push rod downward through the action of the thread. The push rod moves downward to push the pushing ring 13 to move downward. The pushing ring 13 moves downward to squeeze the inclined surface of the pushing block 14. The pushing block 14 is squeezed and drives the stirring blade 3 to move toward the inner wall of the reactor 1 until the inner wall of the reactor 1 fits the stirring blade 3. At this time, the stirring blade 3 moves to clean the inner wall of the reactor 1; when the discharge is completed, it is only necessary to rotate the screw 16 in the opposite direction. At this time, the pushing ring 13 moves upward and no longer squeezes the pushing block 14. The telescopic rod 8 drives the stirring blade 3 to return to its initial position under the pull of the tension spring, thereby resetting the stirring blade 3, thereby avoiding the stirring blade 3 always contacting the inner wall of the reactor 1 during the processing of the reactor 1 and causing wear of the inner wall.

[0055] As a further solution of this embodiment, the lifting mechanism includes a take-up rod 17 rotatably arranged at the front and rear ends of the rotating shaft 2, and a take-up roller 18 is fixedly installed at the bottom end of the take-up rod 17. A pull rope 19 is fixedly installed on the surface of the two take-up rollers 18. The other end of the rear pull rope 19 is wound around the outer side of the rear take-up roller 18 and is fixedly connected to the rear end top of the lifting block 10. A mounting ring 20 is fixedly installed on the front side of the bottom end of the rotating shaft 2, and the other end of the front pull rope 19 passes through the mounting ring 20 and is fixedly connected to the front bottom of the lifting block 10. A first transmission disk 21 is fixedly installed on the outer side of the take-up rod 17, and a support rod 22 is fixedly installed on the right end of the rotating shaft 2. The right end of the support rod 22 is slidably connected to the support plate 23 , the bottom end of the support plate 23 is rotatably connected to two second transmission plates 24, the two second transmission plates 24 transmit to each other, the front second transmission plate 24 and the front first transmission plate 21 transmit to each other, and a transmission ring 25 is fixedly installed at the inner center position of the push ring 13, and the front second transmission plate 24 corresponds to the inner wall of the transmission ring 25. A C-shaped rod 26 is fixedly installed at the right end of the support plate 23, and a first trigger mechanism is provided at the rear end of the C-shaped rod 26. The first trigger mechanism is used to push the C-shaped rod 26 forward when the lifting block 10 can no longer move upward, and a second trigger mechanism is provided at the front end of the C-shaped rod 26. The second trigger mechanism is used to push the C-shaped rod 26 backward when the lifting block 10 can no longer move downward;

[0056] During operation, the pushing ring 13 moves downward to drive the transmission ring 25 to move downward. At this time, the transmission ring 25 and the front second transmission disc 24 transmit each other, and the rotation of the rotating shaft 2 drives the first transmission disc 21 and the second transmission disc 24 to rotate around the rotating shaft 2. Since the transmission ring 25 is in a stationary state, the transmission ring 25 drives the second transmission disc 24 to rotate. The rotation of the front second transmission disc 24 drives the front first transmission disc 21 to rotate. The rotation of the front first transmission disc 21 drives the front take-up roller 18 to rotate. The front take-up roller 18 rotates to wind the front pull rope 19 to its outside and pull the lifting block 10 downward. When the lifting block 10 cannot move downward, the second trigger mechanism is activated by the C-shaped The rod 26 and the support plate 23 drive the two second transmission discs 24 to move backward until the rear second transmission disc 24 is respectively in contact with the rear first transmission disc 21 and the transmission ring 25. At this time, the transmission ring 25 drives the rear first transmission disc 21 to rotate through the rear second transmission disc 24. The rotation of the rear first transmission disc 21 drives the rear take-up roller 18 to rotate. The rear take-up roller 18 rotates to wrap the rear pull rope 19 around its outside and pull the lifting block 10 upward. When the lifting block 10 can no longer move upward, the first trigger mechanism pushes the two second transmission discs 24 to move forward. Similarly to the above, it is achieved that the lifting block 10 is driven to reciprocate up and down while the rotating shaft 2 rotates.

[0057] As a further solution of this embodiment, the first trigger mechanism includes a first extrusion rod 27 slidably connected to the right side of the top end of the lifting slot 9. The right end of the first extrusion rod 27 passes through the rotating shaft 2 and is fixedly mounted with a first special-shaped rod 28. The bottom end of the first special-shaped rod 28 is slidably connected to a first wedge block 29 via a compression spring. The inclined surface of the first wedge block 29 is in contact with the bottom end of the C-shaped rod 26. The top end of the first special-shaped rod 28 is slidably connected to a first wedge rod 30.

[0058] During operation, the lifting block 10 pushes the first extrusion rod 27 upward as it moves upward, and the upward movement of the first extrusion rod 27 drives the first special-shaped rod 28, the first wedge block 29 and the first wedge rod 30 to move upward. During the upward movement of the first wedge block 29, it is blocked by the C-shaped rod 26 and slides to accumulate force until the first wedge rod 30 no longer blocks the C-shaped rod 26. At this time, the first wedge block 29 pushes the C-shaped rod 26 forward under the action of the compression spring, so that the rear second transmission plate 24 no longer contacts the rear first transmission plate 21, and the front second transmission plate 24 contacts the front first transmission plate 21 for transmission.

[0059] As a further solution of this embodiment, the second trigger mechanism includes a second extrusion rod 31, the bottom end of which is slidably connected to the lifting slot 9 via a compression spring. A second special-shaped rod 32 is fixedly installed on the right side of the top end of the second extrusion rod 31. The top end of the second special-shaped rod 32 is slidably connected to a second wedge block 33 via a compression spring. The bottom end of the second special-shaped rod 32 is slidably connected to a second wedge rod 34 via a tension spring. The front end of the second wedge rod 34 is tightly fitted with the C-shaped rod 26.

[0060] During operation, the lifting block 10 pushes the second extruding rod 31 to move downward as it moves downward, and the second extruding rod 31 moves downward, driving the second special-shaped rod 32, the second wedge block 33 and the second wedge rod 34 to move downward. During the downward movement of the second wedge block 33, it is blocked by the C-shaped rod 26 and slides to accumulate force until the second wedge rod 34 no longer blocks the C-shaped rod 26. At this time, the second wedge block 33 pushes the C-shaped rod 26 to move backward under the action of the compression spring, so that the front second transmission plate 24 no longer contacts the front first transmission plate 21, and the rear second transmission plate 24 contacts the rear first transmission plate 21 for transmission.

[0061] As a further solution of this embodiment, a shielding plate 35 is fixedly installed on the outer side of the rotating shaft 2. The shielding plate 35 is located above the transmission ring 25 and shields it. The top end of the take-up rod 17 is rotatably connected to the shielding plate 35.

[0062] During operation, the baffle 35 continuously blocks the transmission ring 25, the first transmission disk 21 and the second transmission disk 24, thereby preventing materials from falling onto the surfaces of the three and affecting the transmission between them. When the rotating shaft 2 rotates, the baffle 35 drives the two take-up rods 17 to rotate around the rotating shaft 2.

[0063] As a further solution of this embodiment, the flip mechanism includes a flip rod 36 fixedly installed at one end of the two scrapers 12 close to each other, and the flip rod 36 passes through the slide bar 11 and is rotatably connected thereto. A locking mechanism is provided at one end of the slide bar 11 close to the scraper 12, and the locking mechanism is used to fix the flip rod 36 to the slide bar 11 when the scraper 12 moves downward, and to unlock the flip rod 36 from the slide bar 11 when the scraper 12 moves upward. A stop rod 37 is fixedly installed on one side of the top of the stirring blade 3 close to the scraper 12, and the stop rod 37 is tightly fitted with the top of the scraper 12. A stop block 38 and a transmission rod 50 are fixedly installed on one end of the slide bar 11 close to the scraper 12, and the other end of the transmission rod 50 is slidably connected to the stirring blade 3;

[0064] During operation, when the slide bar 11 moves downward, the slide bar 11 drives the scraper 12 to move downward. During the downward movement of the scraper 12, the material accumulated on the surface of the mixing blade 3 is scraped downward. When the scraper 12 can no longer move downward, the locking mechanism unlocks the flip rod 36; during the upward movement of the scraper 12, the scraper 12 rotates around the flip rod 36 as the center until the bottom surface of the scraper 12 is blocked by the stopper 38. At this time, the scraper 12 is in an inclined state and the scraper 12 no longer contacts the mixing blade 3; when the scraper 12 can no longer move upward, the top of the scraper 12 is blocked by the stop rod 37 and slowly returns to a horizontal state under the push of the stop rod 37 until the scraper 12 can no longer move upward. At this time, the locking mechanism re-locks the flip rod 36, thereby preparing for the next downward scraping.

[0065] As a further solution of this embodiment, the locking mechanism includes a locking rod 39 slidably connected to the middle portion of the slide bar 11 via a compression spring. The end of the locking rod 39 passes through the flip bar 36 and is slidably connected thereto. A wedge-shaped groove 40 is defined in the middle portion of the locking rod 39. An unlocking rod 41 is slidably connected to the bottom end of the slide bar 11. The top end of the unlocking rod 41 corresponds to the inclined surface of the inner wall of the wedge-shaped groove 40.

[0066] During operation, when the scraper 12 moves downward and is about to touch the bottom, the unlocking rod 41 is blocked by the bottom wall of the reactor 1. Compared with the upward movement of the sliding rod 11, the unlocking rod 41 moves to squeeze the inclined surface of the wedge-shaped groove 40, so that the locking rod 39 slowly slides out from the inner side of the flip rod 36 until the scraper 12 can no longer move downward. At this time, the locking rod 39 no longer locks the flip rod 36.

[0067] As a further solution of this embodiment, the packing mechanism includes a packing plate 42 rotatably connected to the top of the mounting plate 4 via a torsion spring. A hole is formed in the middle of the packing plate 42 to match the hole of the mounting plate 4. A packing box 43 is fixedly mounted on the inner wall of the top right end of the reactor 1. The top of the packing box 43 corresponds to the second packing port 6. A blocking mechanism is provided at the left end of the packing box 43. The blocking mechanism is used to block the rotation of the packing plate 42 when the packing plate 42 rotates one circle, so that the hole in the middle of the packing plate 42 is aligned with the hole in the middle of the mounting plate 4.

[0068] During operation, the initiator is first added into the stuffing box 43 from the second stuffing port 6. When the rotating shaft 2 rotates, the rotating shaft 2 drives the mounting plate 4 and the stuffing plate 42 to rotate synchronously. The stuffing plate 42 rotates so that the holes of the stuffing plate 42 slide through the bottom end of the stuffing box 43 one by one. When the bottom end of the stuffing box 43 is aligned with the holes of the stuffing plate 42, the initiator in the stuffing box 43 falls into the holes of the stuffing plate 42. As the stuffing plate 42 rotates, the holes of the stuffing plate 42 can be filled with the initiator. When the stuffing plate 42 rotates one circle, the blocking mechanism blocks the stuffing plate 43. 2 no longer rotates with the mounting plate 4, and the mounting plate 4 continues to rotate so that the middle hole thereof is aligned with the hole of the filling plate 42. At this time, the initiator in the hole of the filling plate 42 passes through the mounting plate 4 and falls into the raw material. The mounting plate 4 continues to rotate to push the filling plate 42 to rotate. At this time, the blocking mechanism no longer blocks the filling plate 42, and the filling plate 42 returns to its initial state under the action of the torsion spring. The reciprocating operation realizes the uniform addition of initiator in small amounts and multiple times, avoiding the situation where too much initiator is added at one time, causing some raw materials to over-react while some raw materials cannot react.

[0069] As a further solution of this embodiment, the blocking mechanism includes two limit blocks 44 fixedly mounted on the left end of the rotating shaft 2, a limit rod 45 fixedly mounted on the top end of the filler plate 42, the limit rod 45 abutting against the front limit block 44, and a blocking rod 46 slidably connected to the left end of the filler box 43 via a tension spring, the bottom end of the blocking rod 46 being wedge-shaped;

[0070] During operation, the rotation of the filler plate 42 drives the limit rod 45 to rotate around the rotating shaft 2. The movement of the limit rod 45 is blocked by the blocking rod 46 and no longer moves until the front end of the rear limit block 44 squeezes the limit rod 45. At this time, the limit rod 45 squeezes the inclined surface of the blocking rod 46, and the blocking rod 46 is squeezed and moves upward to make way, so that the limit rod 45 is no longer blocked, thereby achieving one blockage for each rotation of the limit rod 45.

[0071] As a further solution of this embodiment, a blocking rod 47 is slidably connected to the middle portion of the left side of the mounting plate 4. The top of the blocking rod 47 is in the same horizontal plane as the top of the mounting plate 4. A blocking ring 48 is fixedly mounted on the top of the push ring 13. The top of the blocking ring 48 is tightly fitted with the blocking rod 47. The surface of the filler plate 42 is slidably connected to a plurality of synchronization rods 49 corresponding one to one with the holes in the middle thereof.

[0072] During operation, the screw 16 is rotated first. The rotation of the screw 16 drives the blocking ring 48 to move downward through the push ring 13. The blocking ring 48 moves downward so that the blocking rod 47 is no longer limited and moves downward under the action of gravity. Then the rotating shaft 2 is driven to rotate until the hole of the filling plate 42 is aligned with the hole of the mounting plate 4. At this time, one of the synchronization rods 49 moves to the top of the blocking rod 47 and moves downward under the action of gravity and is inserted into the mounting plate 4. At this time, the mounting plate 4 and the filling plate 42 are fixed into a whole. When the holes of the mounting plate 4 and the filling plate 42 are aligned with the first filling port 5, the rotating shaft 2 is no longer driven to rotate. Then, raw materials are added to the reactor 1 through the first filling port 5. The raw materials pass through the holes of the mounting plate 4 and the filling plate 42 and fall into the reactor 1, thereby avoiding the device from hindering the filling operation of the reactor 1.

[0073] The preparation process of the environmentally friendly sludge conditioning agent comprises the following steps:

[0074] Step 1: Add the raw materials into the reactor 1 and fill the initiator into the stuffing box 43. The rotating shaft 2 rotates through the stuffing mechanism to fill the initiator in the stuffing box 43 into the raw materials in small amounts and multiple times.

[0075] Step 2: When the reaction is completed, the pushing mechanism pushes the stirring blade 3 to fit the inner wall of the reactor 1, and the rotating shaft 2 rotates to drive the stirring blade 3 to scrape the inner wall of the reactor 1;

[0076] Step 3: While the rotating shaft 2 rotates, the scraper 12 is driven by the lifting mechanism and the flipping mechanism to repeatedly scrape downward on the surface of the mixing blade 3. While scraping downward, the scraper 12 scrapes away the material scraped off by the mixing blade 3.
