Description

Technical Field

[0001] This invention relates to the field of sludge treatment, and in particular to a trough-type turning and turning machine for sludge treatment. Background Technology

[0002] In the field of sludge treatment, aerobic fermentation is an important process for achieving sludge reduction, harmlessness, and resource utilization, and turning equipment is one of the core equipment of this process.

[0003] Traditional trough-type compost turners use a turning shaft to drive the rake teeth to rotate, which in turn the sludge in the fermentation tank. However, during the turning process, the rake teeth may become entangled with fibers, strips of cloth, and other debris from the sludge, thus reducing the turning efficiency of the sludge. Summary of the Invention

[0004] To address the issue that fibers, strips of cloth, and other debris may become entangled in the sludge during the turning process, thereby reducing the turning efficiency of the sludge, this application provides a trough-type turning machine for sludge treatment.

[0005] The trough-type compost turner for sludge treatment provided in this application adopts the following technical solution: A trough-type turning machine for sludge treatment includes a main frame mounted on a fermentation tank. Mounting brackets are fixed to both ends of the bottom surface of the main frame. A rotating shaft is rotatably mounted between two mounting brackets. Multiple turning shafts are arranged on the outer circumference of the rotating shaft. Rake teeth are provided at the end of each turning shaft away from the rotating shaft. Insertion grooves are formed on the sides of the rake teeth, and cutters are installed within the insertion grooves. A drive mechanism for driving the rotating shafts to rotate is provided on the main frame.

[0006] By adopting the above technical solution, a cutter is installed in the insertion groove on the side of the rake teeth. When the turning shaft rotates and turns the sludge, if fibers, cloth strips and other debris are wrapped around the rake teeth, the cutter is thrown out of the insertion groove under the action of centrifugal force, so that the cutter cuts off the fibers, cloth strips and other debris wrapped around the rake teeth, effectively preventing the rake teeth from being wrapped by fibers, cloth strips and other debris, thereby improving the turning efficiency of the rake teeth on the sludge.

[0007] Preferably, a rotating ring is rotatably provided at the end of the turning shaft away from the rotating shaft, the rake teeth are fixed to the end face of the rotating ring away from the rotating shaft, an annular groove is formed on the inner circumferential surface of the rotating ring, a torsion spring is provided in the annular groove, one end of the torsion spring is fixedly connected to the inner wall of the annular groove, and the other end of the torsion spring is fixedly connected to the outer circumferential surface of the turning shaft.

[0008] By adopting the above technical solution, when the rake teeth encounter hard rocks or metal and other unbreakable obstacles, the rotating ring can overcome the torsion spring force to generate a certain angle to drive the rake teeth to rotate and avoid them, thus preventing the rake teeth from directly and rigidly impacting the obstacles and causing damage. This provides overload protection and extends the service life of the rake teeth.

[0009] Preferably, the inner circumferential surface of the insertion slot is provided with an arc-shaped groove, a protrusion is fixed on the end face of the cutter, the protrusion is disposed in the arc-shaped groove, the outer circumferential surface of the protrusion is spaced apart from the inner circumferential surface of the arc-shaped groove, a movable groove is provided on the top surface of the protrusion, the movable groove passes through the protrusion vertically, a limiting rod is fixed on the inner bottom surface of the arc-shaped groove, and the top end of the limiting rod passes through the movable groove and is fixed to the inner top surface of the arc-shaped groove.

[0010] By adopting the above technical solution, when the rake teeth encounter an obstacle and rotate, the rake teeth drive the drive block to rotate, and the drive block pushes the protrusion to move during the rotation, thereby causing the protrusion to drive the cutter to move, so that the cutter moves out of the insertion groove to cut off the fibers, strips of cloth and other debris wrapped on the rake teeth.

[0011] Preferably, a spring is fixed to the outer peripheral surface of the limiting rod, and the end of the spring away from the limiting rod is fixed to the inner wall of the moving groove.

[0012] By adopting the above technical solution, after the cutter is thrown out of the insertion slot under the action of centrifugal force, the cutter is moved into the insertion slot under the action of spring force, so that the cutter can be thrown out of the insertion slot again.

[0013] Preferably, the drive mechanism includes a motor fixed to the top surface of the main frame, a drive sprocket is provided on the output shaft of the motor, a driven sprocket is provided on the rotating shaft, and a transmission chain is provided on the drive sprocket and the driven sprocket.

[0014] By adopting the above technical solution, starting motor one, the output shaft of motor one drives the drive sprocket one to rotate, the drive sprocket one drives the transmission chain one to rotate, the transmission chain one drives the driven sprocket one to rotate, thereby the transmission sprocket one drives the rotating shaft to rotate, the rotating shaft drives the throwing shaft to rotate, and the throwing shaft drives the rake teeth to rotate and throw the sludge.

[0015] Preferably, a movable frame is provided below the main frame, the mounting frame and the transmission chain pass through the movable frame, and guide rods are fixed at the top corners of the movable frame. The top ends of the guide rods pass through the main frame, and the guide rods are slidably connected to the main frame in the vertical direction. A power component for driving the guide rods to move vertically is provided on the movable frame.

[0016] By adopting the above technical solution, the starting force component and the power component drive the mounting frame to move vertically, so that the mounting frame drives the rotating shaft to move vertically, thereby facilitating the adjustment of the rake teeth's turning depth of the sludge. When the mounting frame moves vertically, the guide rod guides the mounting frame, thereby making the mounting frame more stable when moving vertically.

[0018] By adopting the above technical solution, the second motor is started, and the output shaft of the second motor drives the drive shaft to rotate. The two threaded sections on the drive shaft drive the two drive blocks to move in the direction of moving closer to or further away from each other, causing the support rod to rotate, thereby causing the support rod to drive the mounting frame to move vertically.

[0022] By adopting the above technical solution, the second motor is started, the output shaft of the second motor drives the second drive sprocket to rotate, the second drive sprocket drives the second transmission chain to rotate, the second transmission chain drives the second driven sprocket to rotate, thereby causing the second driven sprocket to drive the rotating shaft to rotate, and the rotating shaft to drive the moving wheel to rotate.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. A cutter is installed in the insertion groove on the side of the rake teeth. When the turning shaft rotates and turns the sludge, if fibers, cloth strips and other debris are wrapped around the rake teeth, the cutter is thrown out of the insertion groove under the action of centrifugal force. The cutter cuts the fibers, cloth strips and other debris wrapped around the rake teeth, effectively preventing the rake teeth from being wrapped by fibers, cloth strips and other debris, thereby improving the turning efficiency of the rake teeth on the sludge. 2. When the rake teeth encounter hard rocks or metal and other unbreakable obstacles, the rotating ring can overcome the torsion spring force to generate a certain angle to drive the rake teeth to rotate and avoid them, thus preventing the rake teeth from being directly and rigidly impacted by the obstacle and damaged. This provides overload protection and extends the service life of the rake teeth. 3. The starting force component and power component drive the mounting frame to move vertically, which in turn drives the rotating shaft to move vertically.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a trough-type turning and turning machine for sludge treatment.

A limiting rod 27 passes through the moving groove 26, with its two ends fixed to the inner bottom and top surfaces of the arc-shaped groove 23, respectively. Multiple springs 25 are fixed at equal intervals vertically on the outer circumferential surface of the limiting rod 27, with the end of each spring 25 away from the limiting rod 27 fixed to the inner wall of the moving groove 26.

[0033] Reference Figure 1 and Figure 4 Motor 3 is fixed at both ends of the top surface of the main frame 1. A drive sprocket 31 is fixedly mounted on the output shaft of motor 3. Driven sprockets 32 are fixedly mounted at both ends of the rotating shaft 12. A transmission chain 33 is mounted on the drive sprocket 31 and the driven sprocket 32. A protective cover 34 is mounted on the outer circumference of the transmission chain. The protective cover 34 is rotatably connected to the rotating shaft 12 and the output shaft of motor 3. The protective cover 34 includes a left half cover 341 and a right half cover 342, which are fixedly connected by bolts.

[0034] Reference Figure 1A movable frame 4 is installed below the main frame 1, through which the mounting frame 11 and the transmission chain 33 pass. Guide rods 42 are fixed at the corners of the top surface of the movable frame 4, with their top ends passing through the main frame 1 and slidingly connected vertically to the main frame 1. A limiting sleeve 41 is threaded onto the outer circumferential surface of the guide rod 42, and the top surface of the limiting sleeve 41 abuts against the bottom surface of the main frame 1. Two support rods 43 are hinged to both sides of the bottom surface of the main frame 1. Two parallel fixing blocks 44 are fixed to both sides of the top surface of the movable frame 4. A drive shaft 45 is rotatably mounted between the two fixing blocks 44, and two drive blocks 46 are sleeved on the drive shaft 45. The bottom ends of the two support rods 43 on one side of the bottom surface of the main frame 1 are respectively hinged to the top surfaces of the two drive blocks 46 at one end of the top surface of the movable frame 4. Two threaded sections 47 with opposite directions of rotation are formed on the outer circumferential surface of the drive shaft 45, and the drive blocks 46 are threadedly connected to the outer walls of the threaded sections 47. Motor 2 48 is fixed on both sides of the top surface of the mobile frame 4, and the output shaft of motor 2 48 is fixedly connected to one end of the drive shaft 45.

[0035] Reference Figure 1 Two parallel fixed seats 5 are fixed on both sides of the bottom surface of the movable frame 4. A rotating shaft 51 is rotatably connected between the two fixed seats 5. A movable wheel 52 is fixed at both ends of the rotating shaft 51. A motor 3 53 is fixed on both sides of the top surface of the movable frame 4. A driving sprocket 2 54 is sleeved and fixed on the output shaft of the motor 3 53. A driven sprocket 2 55 is sleeved and fixed on the rotating shaft 51. A transmission chain 2 56 is wound around the driving sprocket 2 54 and the driven sprocket 2 55. The transmission chain 2 56 passes through the movable frame 4.

[0036] The implementation principle of a trough-type compost turner for sludge treatment according to an embodiment of this application is as follows: When it is necessary to turn over the sludge in the fermentation tank, the staff starts the motor 3 53. The output shaft of the motor 3 53 drives the drive sprocket 2 54 to rotate. The drive sprocket 2 54 drives the transmission chain 2 56 to rotate. The transmission chain 2 56 drives the rotating shaft 51 to rotate, which in turn drives the moving wheel 52 to rotate. The moving wheel 52 then moves the moving frame 4 to the top of the fermentation tank. The staff then stands on the moving frame 4 and fixes the turning shaft 13 to the outer circumference of the rotating shaft 12 with bolts.

[0037] After the turning shaft 13 is fixed, the worker rotates the limiting cylinder 41, moving it to the bottom of the guide rod 42. Then, the worker removes the moving frame 4 and starts the second motor 48. The output shaft of the second motor 48 drives the drive shaft 45 to rotate, which in turn drives the two drive blocks 46 to move away from each other. This causes the drive blocks 46 to rotate the support rod 43, which in turn moves the top of the support rod 43 downward. This causes the support rod 43 to move the main frame 1 downward, which in turn moves the rotating shaft 12 downward, causing the rake teeth 2 on the turning shaft 13 to fall into the sludge. Then, the first motor 3 is started. The output shaft of the first motor 3 drives the drive sprocket 31 to rotate, which in turn drives the transmission chain 33 to rotate. The transmission chain 33 drives the driven sprocket 32 ​​to rotate, which in turn drives the rotating shaft 12 to rotate. The rotating shaft 12 then drives the turning shaft 13 to rotate, which in turn drives the rake teeth 2 to rotate. This causes the rake teeth 2 to turn and scatter the sludge in the fermentation tank during rotation. When fibers, cloth strips and other debris become entangled on the rake teeth 2, the cutter 22 is thrown out of the insertion groove 21 by the centrifugal force generated during the rotation of the rake teeth 2, so that the cutter 22 extends out to cut the fibers, cloth strips and other debris entangled on the rake teeth 2, thereby reducing the frequency of manual cleaning and improving the efficiency of sludge turning and throwing in the fermentation tank.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
