Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, and more specifically to a mechanical sludge cell wall breaking device. Background Technology

[0002] Sludge cell disruption is a method for treating sludge that aims to break down the cell walls of microorganisms within the sludge, releasing intracellular substances for better recycling and utilization. These substances include proteins, nucleic acids, and polysaccharides, which have potential economic value. There are various methods for sludge cell disruption, including mechanical disruption, ultrasonic disruption, chemical dissolution, and enzymatic hydrolysis. Mechanical disruption includes ball milling, stirred crushers, and shear crushing.

[0003] Currently, the sludge cell shearing method utilizes the principle of high pressure or high shear force to force sludge through a narrow slit or orifice, causing the cells to break down under strong shear force during the shearing process. However, most existing sludge shearing orifices cannot change their aperture. Since the sludge is in large pieces in the early stages of treatment, if the orifice is small in order to improve the sludge treatment effect, it will be difficult for the sludge to pass through the orifice, thus reducing the sludge treatment efficiency. On the other hand, if the aperture is large, the sludge can easily pass through the orifice, which will reduce the sludge breaking effect. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this invention provides a mechanical sludge cell wall breaking device. By varying the inner diameter of the feed pipe, the feed pipe can transport sludge of different block sizes. The sludge is then sheared by two positive spiral cones and two negative spiral cones inside the inner pipe. Furthermore, the sludge is repeatedly sheared by the guide ring plate on the outer pipe and the baffle ring plate on the rotating screen. Simultaneously, centrifugal force propels the sludge through the material hole into the tank, where the dividing spikes further break it down. This allows for comprehensive, multi-directional, and multi-layered treatment of the sludge, improving the practicality of the invention and making it adaptable to sludge of different specifications, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mechanical sludge cell wall breaking device, comprising a tank, wherein the tank is provided with processing components for sludge treatment; The processing assembly includes an outer tube disposed inside the tank, a feed pipe movably connected to the top of the outer tube via a bearing, the top and bottom of the outer tube penetrating the tank, and the top of the outer tube movably connected to the inner wall of the tank via a sealed bearing, and a functional component for secondary shearing processing of sludge is provided on the outside of the outer tube. The outer tube is equipped with an inner tube, and a rotary joint for connecting the outer tube is installed at the top of the inner tube. The inner diameter of the top of the feed pipe is larger than the inner diameter of the bottom of the feed pipe, and the inner diameter of the bottom of the feed pipe is equal to the inner diameter of the top of the rotary joint. Two sets of shearing components for crushing sludge are installed inside the inner tube, and a guide block installed inside the outer tube is provided at the bottom of the inner tube. Each set of shearing components includes two positive spiral cones and two negative spiral cones that are evenly spaced and staggered. The functional component includes a fixed ring, which is sleeved on the outside of the bottom end of the outer tube and is movably connected to the inner wall of the tank through a sealed bearing. A rotating screen barrel sleeved on the outside of the outer tube is installed at the top of the fixed ring, and multiple baffle ring plates are installed inside the rotating screen barrel. A flow guide ring plate is provided between two adjacent baffle ring plates. The flow guide ring plate is sleeved on the outside of the outer tube. Multiple liquid holes are provided between two adjacent flow guide ring plates on the outside of the outer tube. The outer tube drives the flow guide ring plate to rotate, and at the same time, the rotating screen barrel drives the baffle ring plate to rotate. Then, the sludge is repeatedly sheared by the flow guide ring plate and the baffle ring plate. The rotary screen barrel has multiple spaced material holes on its exterior, top, and bottom. Each material hole is equipped with multiple spaced dividing spikes. These dividing spikes facilitate the cutting of sludge after repeated shearing.

[0006] In a preferred embodiment, a first support plate is installed on one side of the bottom of the tank, and a first motor is installed on the top of the first support plate. The output shaft of the first motor passes through the first support plate and is equipped with a first main pulley. A first driven pulley is provided on the side of the first main pulley near the tank and sleeved outside the bottom of the fixed ring. A first belt is provided between the first main pulley and the first driven pulley. The first main pulley and the first driven pulley are driven by the first belt. By driving the first main pulley and the first driven pulley by the first belt, the first motor can drive the fixed ring to drive the rotating screen barrel to rotate, and drive the baffle ring plate on the rotating screen barrel to repeatedly shear the sludge.

[0007] In a preferred embodiment, a second support plate is installed on the side of the tank bottom away from the first support plate, and a second motor is installed on the top of the second support plate. The output shaft of the second motor passes through the second support plate and is equipped with a second main pulley. A second driven pulley is provided on the side of the second main pulley near the tank and sleeved on the outside of the bottom of the outer tube. A second belt is provided between the second main pulley and the second driven pulley. The second main pulley and the second driven pulley are driven by the second belt. By driving the second main pulley and the second driven pulley by the second belt, the second motor can drive the outer tube to rotate the guide ring plate. By cooperating with the baffle ring plate, the sludge can be repeatedly sheared.

[0008] In a preferred embodiment, a discharge pipe is fixedly connected to the bottom of the tank, through which the treated sludge is discharged.

[0009] In a preferred embodiment, the bottom inner diameter of the rotary joint is smaller than the top inner diameter of the rotary joint, and the cross-section of the rotary joint is set to V-shape. By setting the top diameter of the rotary joint to be larger than the bottom diameter of the rotary joint, the top capacity of the rotary joint is larger, which facilitates the flow of sludge.

[0010] The technical effects and advantages of this invention are as follows: By changing the inner diameter of the feed pipe, the feed pipe can transport sludge of different block sizes, thereby effectively preventing sludge blockage, improving sludge transport efficiency and the practicality of the invention. The two positive spiral cones and two negative spiral cones distributed alternately inside the inner tube facilitate multi-level shearing of the sludge. Then, through the repeated contact between the guide ring plate on the outer tube and the baffle ring plate on the rotating screen, the sludge can be repeatedly sheared. At the same time, centrifugal force is used to discharge the sludge into the tank through the material hole, and the dividing spikes in the material hole can further break the sludge, thereby achieving the effect of completely breaking the sludge cell wall. Moreover, this invention can comprehensively treat sludge in multiple directions and at multiple levels, thus improving the practicality of the invention. The first belt drives the first main pulley and the first driven pulley, which in turn drives the rotating screen barrel on the fixed ring to rotate counterclockwise. The second belt drives the second main pulley and the second driven pulley, which in turn drives the outer tube to rotate clockwise. This allows the baffle ring plate and the guide ring plate to repeatedly shear the sludge, thereby improving the sludge treatment effect. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Refer to the instruction manual appendix Figure 1-7 The present invention provides a mechanical sludge cell wall breaking device, including a tank 1, wherein the tank 1 is provided with a processing component for sludge treatment. The processing assembly includes an outer tube 2 disposed inside the tank body 1. The top end of the outer tube 2 is movably connected to a feed pipe 25 via a bearing. Both the top and bottom ends of the outer tube 2 penetrate the tank body 1, and the top end of the outer tube 2 is movably connected to the inner wall of the tank body 1 via a sealed bearing. A functional component for secondary shearing of sludge is provided outside the outer tube 2. An inner tube 3 is disposed inside the outer tube 2. A rotary joint 4 for connecting the outer tube 2 is installed at the top end of the inner tube 3. The inner diameter of the top end of the feed pipe 25 is larger than the inner diameter of the bottom end of the feed pipe 25, and the inner diameter of the bottom end of the feed pipe 25 is equal to the inner diameter of the top end of the rotary joint 4. The inner diameter of the rotary joint 4 is smaller at the bottom than at the top, and the cross-section of the rotary joint 4 is V-shaped. By making the diameter at the top of the rotary joint 4 larger than the diameter at the bottom, the capacity at the top of the rotary joint 4 is larger, which facilitates the flow of sludge and prevents sludge blockage. The inner tube 3 is equipped with two sets of shearing components for crushing sludge, and the bottom of the inner tube 3 is provided with a guide block 5 installed inside the outer tube 2. Each set of shearing components includes two positive spiral cones 6 and two negative spiral cones 7 that are evenly spaced and staggered.

[0015] First, the staff uses a multi-stage centrifugal pump to transport the sludge through the feed pipe 25 to the inner pipe 3 inside the tank 1. Then, the first motor 16 and the second motor 21 are started simultaneously. The second motor 21 drives the outer pipe 2 to rotate through the second main pulley 22 and the second slave pulley 23 driven by the second belt 24. At the same time, the inner pipe 3 drives the two positive spiral cones 6 and the two negative spiral cones 7 in the shearing component to rotate together with the outer pipe 2 through the rotary joint 4. In this way, the sludge can be sheared at high speed, so that the floc structure of the sheared sludge is destroyed, which is conducive to the subsequent cell wall breaking treatment. The sheared sludge moves upward through the guide block 5 and is discharged through the liquid hole 12 to the space between the guide plate on the outer pipe 2 and the baffle plate on the rotary screen 9. Simultaneously, the first motor 16 drives the rotating screen 9 on the fixed ring 8 via the first main pulley 17 and the first driven pulley 18, which are driven by the first belt 19. The rotating screen 9 then drives the baffle plate to rotate. The sludge is repeatedly sheared and broken down by the guide plate that rotates clockwise with the outer pipe 2 and the baffle plate that rotates counterclockwise with the rotating screen 9. Under the action of centrifugal force, the sludge is discharged into the tank 1 through the material hole 13. The aggregates in the sludge are further broken down by the multiple dividing spikes 14 in the material hole 13, thereby achieving the effect of complete wall breaking. Finally, the sludge is discharged to the outside of the tank 1 through the discharge pipe 26, thus realizing the processing of sludge.

[0016] To improve the treatment efficiency of sludge, it is necessary to process the sludge at multiple levels, such as... Figure 3-5 As shown, the functional component includes a fixing ring 8, which is sleeved on the outside of the bottom end of the outer tube 2, and the outside of the fixing ring 8 is movably connected to the inner wall of the tank 1 through a sealed bearing. A rotating screen 9, which is sleeved on the outside of the outer tube 2, is installed at the top of the fixing ring 8, and multiple baffle ring plates 10 are installed inside the rotating screen 9. A guide ring plate 11 is provided between two adjacent baffle ring plates 10. The guide ring plate 11 is sleeved on the outside of the outer tube 2, and multiple liquid holes 12 are provided between two adjacent guide ring plates 11 on the outside of the outer tube 2. The outer tube 2 drives the guide ring plate 11 to rotate, and at the same time, the rotating screen 9 drives the baffle ring plate 10 to rotate. Then, the sludge is repeatedly sheared by the guide ring plate 11 and the baffle ring plate 10, which can improve the treatment effect of the sludge.

[0017] To facilitate comprehensive and in-depth processing of sludge, such as Figure 3 and 4 As shown, the rotary screen 9 has multiple spaced material holes 13 on its exterior, top, and bottom. Each material hole 13 is equipped with multiple spaced dividing spikes 14. Through the multiple dividing spikes 14 in the material hole 13, the sludge after repeated shearing can be easily cut, thereby enhancing the sludge treatment effect.

[0018] To facilitate the shearing of sludge by the baffle ring plate 10 inside the rotary screen barrel 9, such as... Figure 1 and 2 As shown, a first support plate 15 is installed on one side of the bottom of the tank body 1. A first motor 16 is installed on the top of the first support plate 15. The output shaft of the first motor 16 passes through the first support plate 15 and is equipped with a first main pulley 17. A first driven pulley 18 is provided on the side of the first main pulley 17 near the tank body 1 and sleeved outside the bottom of the fixed ring 8. A first belt 19 is provided between the first main pulley 17 and the first driven pulley 18. The first main pulley 17 and the first driven pulley 18 are driven by the first belt 19. The first main pulley 17 and the first driven pulley 18 are driven by the first belt 19, so that the first motor 16 can drive the fixed ring 8 to drive the rotating screen barrel 9 to rotate, and drive the baffle ring plate 10 on the rotating screen barrel 9 to repeatedly shear the sludge.

[0019] Simultaneously, in order to drive the guide ring plate 11 to cooperate with the baffle ring plate 10 to shear the sludge, it is necessary to drive the outer pipe 2 to rotate the guide ring plate 11, such as... Figure 1 and 2 As shown, a second support plate 20 is installed on the side of the bottom of the tank 1 away from the first support plate 15, and a second motor 21 is installed on the top of the second support plate 20. The output shaft of the second motor 21 passes through the second support plate 20 and is equipped with a second main pulley 22. A second driven pulley 23 is provided on the side of the second main pulley 22 near the tank 1 and sleeved on the outside of the bottom of the outer tube 2. A second belt 24 is provided between the second main pulley 22 and the second driven pulley 23. The second main pulley 22 and the second driven pulley 23 are driven by the second belt 24. By driving the second main pulley 22 and the second driven pulley 23 through the second belt 24, the second motor 21 can drive the outer tube 2 to drive the guide ring plate 11 to rotate. By cooperating with the guide ring plate 11 and the baffle ring plate 10, the sludge can be repeatedly sheared, thereby improving the sludge treatment effect.

[0020] To facilitate the output of the treated sludge, such as Figure 1-3 As shown, the bottom of the tank 1 is fixedly connected to a discharge pipe 26, through which the treated sludge is discharged.

[0021] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
