Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment equipment, and in particular to a flocculation and mixing device for a screw stack dewatering machine. Background Art

[0002] With the acceleration of industrialization and the improvement of environmental awareness, sludge treatment has become an important issue in the field of environmental protection. Traditional sludge treatment methods have problems such as low efficiency, large footprint, high operating costs, etc., which are difficult to meet the needs of modern environmental protection. Therefore, the screw stack sludge dewatering machine came into being. The screw stack sludge dewatering machine has significant advantages and broad application prospects in the field of sludge treatment due to its high efficiency, high degree of automation, compact structure, wide range of applications and self-cleaning and other technical characteristics.

[0003] In the prior art, a Chinese patent document with publication number CN115845689B proposes a flocculation mixing tank for a spiral dewatering machine and a method of using the same, comprising a tank body, a support frame installed at the bottom of the tank body, and a discharge valve opened at the bottom of the tank body, and also comprising: a feed port opened at the top of the tank body, a crushing assembly arranged inside the feed port; a fixed frame fixedly installed at the top of the tank body, a rotating motor installed at the top of the fixed frame, and an output end of the rotating motor passing through the fixed frame and extending downward. Although the rapid mixing reaction of the sludge and the agent can be achieved, the rapid reaction of the sludge and the agent at the bottom can be facilitated, adhesion can be avoided, and the discharge is rapid, the technology is consistent with the traditional method in that: in sewage treatment In actual operation, sludge will accumulate at the bottom of the equipment, forming a sediment layer that is not easy to discharge naturally. In this case, it is usually necessary to wait until the entire sewage treatment process is completed before the tedious bottom cleaning operation can be carried out, which undoubtedly prolongs the non-operating time of the equipment and reduces the overall sewage treatment efficiency and continuity; in addition, in order to accelerate the efficient reaction between chemical agents and sludge, the stirring rod configured inside the equipment will rotate at high speed. However, the strong wave effect brought about by this high-speed rotation often inadvertently stirs up the sludge that has been stably settled at the bottom, making the originally clear solid-liquid separation process complicated, further aggravating the difficulty and cost of sewage treatment.

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0021] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figures 1 to 9 As shown, a flocculation and mixing device of a spiral dewatering machine includes a tank body 1 and a tank cover 2 installed at the upper end of the tank body 1. A stirring and scraping assembly is arranged inside and outside the tank body 1. A liquid inlet 3 is fixedly connected to the middle of the tank cover 2. A separation cylinder 37 for solid-liquid separation of sewage is fixedly connected to the middle of the inner bottom surface of the tank body 1. A reciprocating screw 16 is arranged in the middle of the lower end of the separation cylinder 37. The reciprocating screw 16 is externally connected to a discharge assembly for discharging sludge. A water level warning assembly is arranged on one side of the separation cylinder 37. The water level warning assembly is used to remind the user of the water level inside the tank body 1. The device effectively solves the problem that sludge accumulates at the bottom of the device and is difficult to be discharged naturally through the reciprocating screw 16 and the discharge assembly. In the sewage treatment process, the sludge can be discharged smoothly with the operation of the reciprocating screw 16, and there is no need to wait for the entire treatment process to be completed before performing cumbersome bottom cleaning. This design significantly shortens the non-operating time of the equipment, improves the efficiency of sludge treatment, and also enhances the continuity of the entire sewage treatment process. By reducing the number of downtimes for cleaning, equipment can remain in efficient operation for longer periods of time, greatly improving overall processing capacity and economic benefits.

[0023] Further, such as Figures 2 to 3As shown, the stirring and scraping assembly includes a toothed disc 4 which is rotatably connected to the upper end of the tank body 1, one side of the inner wall of the toothed disc 4 is meshed with a gear 5, the upper end face of the gear 5 is fixedly connected to the output end of the servo motor, and the servo motor is arranged on one side of the upper end face of the tank cover 2, and a plurality of stirring rods 6 are evenly and fixedly connected to the outer side of the lower end face of the toothed disc 4, one end of each of the plurality of stirring rods 6 is fixedly connected to a scraper 7, one end face of the scraper 7 is in contact with the inner wall of the tank body 1, and the outer wall of the servo motor output end is located at the upper end of the gear 5 and is fixedly connected to a driving pulley 8, and the external transmission of the driving pulley 8 is connected to a belt 13, and the belt 13 is connected to the belt 13. One end of the belt 13 is connected to the driven pulley 12, and the middle part of the lower end surface of the driven pulley 12 is fixedly connected to the auger blade 11. The lower end of the auger blade 11 extends into the interior of the separation cylinder 37 and is coaxial with the separation cylinder 37. The upper end of the outer wall of the auger blade 11 is fixedly connected to the sliding frame 41. The auger blade 11 is rotatably connected to the separation cylinder 37 through the sliding frame 41. When the servo motor is started, its output end drives the driving pulley 8 to rotate, and through the transmission action of the belt 13, the power is transmitted to the driven pulley 12, thereby driving the auger blade 11 to rotate around the lower part of the tank body 1 and the separation cylinder 37. At the same time, the output end of the servo motor is also directly connected to the gear 5, and the gear 5 is meshed with the toothed disc 4, so that the toothed disc 4 and the multiple stirring rods 6 fixed at the lower end thereof rotate synchronously. During the rotation process, the stirring rod 6 not only promotes the full mixing of sewage and chemical agents and improves the reaction efficiency, but also the scraper rod 7 at its end is close to the inner wall of the tank body 1, effectively scraping off the sludge attached to the wall to prevent agglomeration and clogging. In addition, the rotation of the auger blades 11 not only further enhances the stirring and mixing effects, but also pushes the sewage inside the separation cylinder 37 downward to increase the sedimentation speed of the sludge.

[0024] Further, such as Figure 6 , Figure 8 , Fig. 9As shown, the discharge assembly includes a lifting plate 17 that is transmission-connected to the outside of the reciprocating screw 16, and fan-shaped grooves 38 are provided on both sides of the lifting plate 17. A fixed frame 39 is rotatably connected to the inside of the lifting plate 17. Both sides of the fixed frame 39 are fan-shaped and have an area larger than the fan-shaped grooves 38. The fan-shaped areas on both sides of the fixed frame 39 are fixedly connected to fixed sheets 36. Slide blocks 35 are fixedly connected to both ends of the outer wall of the lifting plate 17. The lifting plate 17 is slidably connected to the inside of the separation cylinder 37 through the slide blocks 35. A guide rod 32 is fixedly connected to one side of the outer wall of the fixed frame 39. The outer wall of the lifting plate 17 is close to the guide rod 32. A sliding groove 33 is provided on one side of the tank body 1, and the guide rod 32 extends out of the lifting plate 17 through the sliding groove 33. A guide groove 26 is provided on one side of the interior of the separation cylinder 37. The upper and lower ends of the guide groove 26 are both vertically arranged, and the middle part of the guide groove 26 is inclined. The guide rod 32 is slidably connected to the inside of the guide groove 26. A pressure rod 34 is fixedly connected to one side of the lower end surface of the lifting plate 17. An opening is provided in the middle part of the lower end surface of the tank body 1, and the middle part of the lower end surface of the tank body 1 is rotatably connected to the annular plate 23 corresponding to the opening. A fixed plate 25 is fixedly connected to one side of the middle part of the lower end surface of the tank body 1, and the lower end of one side end surface of the fixed plate 25 is fixedly connected to the fixing plate 25. A second spring 24 is fixedly connected, and one end of the second spring 24 away from the fixed plate 25 is fixedly connected to one side of the middle part of the lower end surface of the annular plate 23. A connecting shaft 27 is fixedly connected to the middle part of the lower end surface of the auger blade 11. A plurality of fixing seats 29 are evenly fixedly connected to the lower end of the connecting shaft 27. A third spring 30 is fixedly connected to one end of the fixing seat 29. A clamping rod 28 is fixedly connected to one end of the third spring 30. One end of the clamping rod 28 is rotatably connected to the connecting shaft 27. A ratchet groove 31 is provided at the upper end of the reciprocating screw rod 16. The side of the clamping rod 28 away from the rotatably connected to the connecting shaft 27 is engaged with the ratchet groove 31. The lower end of the auger blade 11 is engaged and rotatably connected with the upper end of the reciprocating screw rod 16. The upper end of the separation cylinder 37 is trumpet-shaped. Multiple drainage pipes 14 are evenly spaced and fixedly connected to the upper end of the outer wall of the separation cylinder 37. The multiple drainage pipes 14 are all connected to the separation cylinder 37. A trapezoidal platform 15 is fixedly connected to the middle of the inner wall of the separation cylinder 37. When the discharge assembly is working, the lifting plate 17 is located at the lower end of the trapezoidal platform 15. At this time, the fan-shaped area of ​​the fixed frame 39 rotates to a position that does not block the fan-shaped groove 38, so that the sludge that has undergone preliminary solid-liquid separation can smoothly pass through the fan-shaped groove 38 and fall into the collection area below the lifting plate 17. When discharging is required, the servo motor starts and drives the auger blade 11 to reverse. This reversal action is achieved through the cooperation of the connecting shaft 27, the fixing seat 29, the third spring 30 and the clamping rod 28, so that the clamping rod 28 is engaged with the ratchet groove 31 at the upper end of the reciprocating screw rod 16, thereby realizing the synchronous rotation of the auger blade 11 and the reciprocating screw rod 16. As the reciprocating screw rod 16 rotates, the lifting plate 17 starts to move downward. During the movement, the guide rod 32 slides along the guide groove 26 opened inside the separation cylinder 37.Since the middle part of the guide groove 26 is designed to be inclined, when the lifting plate 17 moves downward to a certain position, the fixed frame 39 is guided by the guide groove 26 and rotates, so that the fan-shaped area gradually covers and closes the fan-shaped groove 38, preventing the sludge from continuing to fall. When the lifting plate 17 moves to the bottom, the pressure rod 34 contacts the annular plate 23 and pushes it to rotate. The rotation of the annular plate 23 opens the lower end of the separation cylinder 37, and the accumulated sludge is discharged. At this time, since the fixed frame 39 has completely closed the fan-shaped groove 38, it is ensured that no sludge will flow back to the top of the lifting plate 17 during the sludge discharge process. After the sludge discharge is completed, the lifting plate 17 moves upward through the reciprocating screw 16. During the ascending process, the fixed frame 39 rotates again to a position that does not block the fan-shaped groove 38, preparing for the next sludge collection. At the same time, the annular plate 23 is reset under the action of the second spring 24, closing the sludge discharge port, and completing the entire discharge process.

[0025] Further, such as Figure 3 , Figure 5As shown, the water level warning assembly includes a ring plate 10 arranged outside the upper end of the separation cylinder 37, an air bag 9 is arranged inside the ring plate 10, a connecting rod 21 is fixedly connected to one side of the lower end surface of the ring plate 10, a connecting seat 20 is fixedly connected to the lower end of the connecting rod 21, and a lifting door 19 is fixedly connected to one end of the connecting seat 20. The lifting door 19 is arc-shaped and coaxial with the separation cylinder 37. A water drain 40 is provided at the lower end of one side of the outer wall of the separation cylinder 37. The lifting door 19 is slidably connected to the separation cylinder 37. The lower end face of the receiving seat 20 is fixedly connected to the side away from the lifting door 19 with a first spring 18, the lower end of the first spring 18 is fixedly connected to the tank body 1, the area of ​​the lifting door 19 is larger than the area of ​​the drain tank 40, the upper end face of the ring plate 10 is fixedly connected to the limit rods 22 on both sides, the upper ends of the two limit rods 22 penetrate the tank cover 2 and are slidably connected to the tank cover 2, and the outer wall of the limit rod 22 is provided with a scale. During the sewage treatment process, as the sewage is continuously injected and treated, the water level in the tank body 1 gradually rises. When the water level rises to contact the airbag 9 inside the ring plate 10, the airbag 9 gradually rises due to the buoyancy of the water. The rise of the airbag 9 is transmitted to the connecting seat 20 through the connecting rod 21, thereby pushing the arc-shaped lifting door 19 to slide upward along the outer wall of the separation cylinder 37. Since the area of ​​the lifting door 19 is larger than the area of ​​the drain groove 40, in the initial state, the lifting door 19 completely closes the drain groove 40 to prevent sewage from being directly discharged without treatment. As the lifting door 19 rises, the first spring 18 is gradually stretched to store elastic potential energy. The lifting door 19 rises to open the waterproof groove. At this time, the worker controls the servo motor to change the output direction, and the discharge assembly no longer runs. The separation cylinder 37 is connected to the liquid inside the tank body 1, which is convenient for discharging. At the same time, the limit rod 22 slides on the tank cover 2 with the rise of the ring plate 10 and the airbag 9. The scale on its outer wall can be used to intuitively display the current water level. When the water level reaches the preset warning line, the operator can quickly stop the water injection work by observing the scale on the limit rod 22.
