[0002] At present, with the comprehensive development of my country's economy and social undertakings, the country's requirements for environmental protection are also increasing, and the number of urban sewage treatment plants is also increasing.

[0003] After decades of development, sludge treatment and disposal technologies in developed countries abroad have become relatively mature. For example, the main methods in Europe are landfill and land use, agricultural use has always been the main method in North America, and Japan mainly uses sludge for building materials after incineration, supplemented by agricultural use and landfill.

[0004] In the existing technology, large rakes and simple rakes are used to clean and dispose of sludge from the sludge treatment tank. Although they can quickly move the sludge out of the sludge treatment tank, they are large in size and occupy a large area. Although the simple rake is simple and occupies less space, its structure is too simple and its working efficiency is low. Summary of the Invention

[0005] In view of the above technical problems, the object of the present invention is to provide a raking structure for a sludge treatment tank to clean out the sludge in the sludge treatment tank.

[0006] The above technical solution of the present invention is achieved by the following methods:

[0007] A raking structure for a sludge treatment tank, used for cleaning sludge in the sludge treatment tank, includes a drive mechanism, a guide rail mechanism, a control mechanism, and a raking mechanism. The side surfaces of the drive mechanism are slidably connected to the side surfaces of the guide rail mechanism, and the ends of the side surfaces of the guide rail mechanism are connected to the control mechanism. The raking mechanism is connected to the control mechanism at both ends. The raking mechanism includes a raking rod, each end of which is connected to a roller, which is in rolling connection with the guide rail mechanism. The raking rod is provided with a switching groove, which is provided with a plurality of rake teeth, which are slidably connected to the switching groove.

[0008] Compared with existing technologies, the present invention has the following advantages: a drive mechanism drives the raking mechanism to reciprocate on a guide rail mechanism, raking the sludge from the tray back and forth to the discharge outlet. A control mechanism calculates the distance the raking mechanism changes in real time during its reciprocating motion and controls the raking mechanism accordingly. The raking mechanism switches the position of the rake teeth during the reciprocating motion, raking the sludge to the discharge outlet all at once, saving raking time and improving work efficiency.

[0009] Further optimized as follows: the driving mechanism includes a first motor, a first rotating wheel, a first fixed rod, a first telescopic rod, a first slider, a second motor, a second rotating wheel, a second fixed rod, a second telescopic rod and a second slider; the output end of the first motor is connected to one end of the first rotating wheel, the other end of the first rotating wheel is connected to one end of the first fixed rod, the other end of the first fixed rod is connected to one end of the first telescopic rod, the other end of the first telescopic rod is connected to the center of the first slider, and the inner side surface of the first slider is slidably connected to one side of the guide rail mechanism; the output end of the second motor is connected to one end of the second rotating wheel, the other end of the second rotating wheel is connected to one end of the second fixed rod, the other end of the second fixed rod is connected to one end of the second telescopic rod, the other end of the second telescopic rod is connected to the center of the second slider, and the inner side surface of the second slider is slidably connected to the other side of the guide rail mechanism.

[0010] Further optimization is: the first motor can be a forward and reverse motor.

[0011] With the above technical solution, when the first motor rotates forward, the first slider drives the rake teeth to move forward, cleaning the sludge to the discharge outlet. When the first motor rotates reversely, the first slider drives the rake teeth to move backward, cleaning the sludge to the discharge outlet, achieving the goal of raking the sludge into the sludge treatment tank in one reciprocating motion.

[0012] Further optimization is: the second motor can be a forward and reverse motor.

[0013] With this technical solution, when the second motor rotates forward, the second slider drives the rake teeth to move forward, cleaning the sludge to the discharge outlet. When the second motor rotates reversely, the second slider drives the rake teeth to move backward, cleaning the sludge to the discharge outlet. The sludge is raked out to the sludge treatment tank in one reciprocating motion.

[0014] By adopting the above technical solution, the driving mechanism drives the raking mechanism to perform a reciprocating motion on the guide rail mechanism to rake out the sludge, which has the advantages of strong power and high working efficiency.

[0015] Further optimization is as follows: the guide rail mechanism includes a first guide rail and a second guide rail, the first guide rail and the second guide rail are parallel, the outer side surface of the first guide rail is slidably connected to the inner side surface of the first slider, and the outer side surface of the second guide rail is slidably connected to the inner side surface of the second slider.

[0021] Further optimization is as follows: the rake teeth are distributed on the rake rod in a comb-teeth shape.

[0022] By adopting the above technical solution, the resistance when raking out the sludge by the comb-tooth type rake teeth is small, which is conducive to one-time cleaning of the sludge.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 and Figure 2 The technical solution of the present invention is further described.

[0032] A raking structure for a sludge treatment tank is used to clean the sludge in the sludge treatment tank, such as Figure 1 As shown, the system comprises a drive mechanism 1, a guide rail mechanism 2, a control mechanism 3, and a rake mechanism 4. The side surfaces of the drive mechanism 1 are slidably connected to the side surfaces of the guide rail mechanism 2, and the side ends of the guide rail mechanism 2 are connected to the control mechanism 3. The two ends of the rake mechanism 4 are respectively connected to the control mechanism 3. The control mechanism 3 is digitally connected to the drive mechanism 1.

[0033] like Figure 1 and Figure 2 As shown, the rake mechanism 4 includes a rake rod 41, each end of which is connected to a roller 43, which is in rolling connection with the guide rail mechanism 2. The rake rod 41 has a switching groove 42, and a plurality of rake teeth 44 are arranged in the switching groove 42. There is a vacant position for a rake tooth 44 between the rake teeth, and the plurality of rake teeth 44 are slidably connected to the switching groove 42. After receiving the command information from the controller 30, the rake rod 41 switches all the rake teeth 44 along the vacant position direction of the switching groove 42 to the vacant position, thereby achieving the purpose of quickly switching the position of the rake teeth 44.

[0034] The rake teeth 44 are arranged in a comb-like pattern on the rake bar 41. These comb-shaped teeth 44 create minimal resistance when raking sludge, facilitating one-step sludge removal. The teeth 44 are made of an alloy. This alloy is strong and durable, allowing for efficient removal of large quantities of sludge at once. The teeth 44 are also detachably connected to the reversing trough 42, facilitating easy maintenance and replacement.

[0035] The drive mechanism 1 drives the raking mechanism 4 to reciprocate on the guide rail mechanism 2, rakes the sludge on the tray back and forth to the discharge outlet. The control mechanism 3 calculates the distance that changes in real time during the reciprocating motion of the raking mechanism 4 and controls the raking mechanism 4 accordingly. The distance refers to the distance between the raking mechanism 4 and the control mechanism 3. The controller 3 controls the reciprocating motion of the starting mechanism. The raking mechanism 4 switches the position of the rake teeth 44 during this reciprocating motion, raking the sludge all at once to the discharge outlet, saving raking time and improving work efficiency.

[0036] like Figure 1As shown, the drive mechanism 1 includes a first motor 10, a first rotating wheel 11, a first fixed rod 12, a first telescopic rod 13, a first slider 14, a second motor 15, a second rotating wheel 16, a second fixed rod 17, a second telescopic rod 18, and a second slider 19. The output end of the first motor 10 is connected to one end of the first rotating wheel 11, the other end of the first rotating wheel 11 is connected to one end of the first fixed rod 12, the other end of the first fixed rod 12 is connected to one end of the first telescopic rod 13, and the other end of the first telescopic rod 13 is connected to the center of the first slider 14. The inner side of the first slider 14 is slidably connected to one side of the guide rail mechanism 2. The first motor 10 can be a forward or reverse rotating motor. When the first motor 10 rotates forward, the first slider 14 drives the rake teeth 44 in a forward motion, clearing the sludge to the discharge outlet. When the first motor 10 rotates reversely, the first slider 14 drives the rake teeth 44 in a reverse motion, clearing the sludge to the discharge outlet, achieving raking of the sludge into the sludge treatment tank in a single reciprocating motion.

[0037] The output end of the second motor 15 is connected to one end of the second rotating wheel 16, the other end of the second rotating wheel 16 is connected to one end of the second fixed rod 17, the other end of the second fixed rod 17 is connected to one end of the second telescopic rod 18, the other end of the second telescopic rod 18 is connected to the center of the second slider 14, and the inner side surface of the second slider 14 is slidably connected to the other side of the guide rail mechanism 2. The second motor 15 can be a forward and reverse motor. When the second motor 15 rotates forward, the second slider 18 drives the rake teeth 44 to move forward, cleaning the sludge to the discharge outlet. When the second motor 15 rotates reversely, the second slider 18 drives the rake teeth to move in the opposite direction, cleaning the sludge to the discharge outlet, thereby raking the sludge into the sludge treatment tank in a one-time reciprocating motion.

[0038] like Figure 1 As shown, the guide rail mechanism 2 includes a first guide rail 21 and a second guide rail 22. The first guide rail 21 and the second guide rail 22 are parallel to each other. The outer side of the first guide rail 21 is slidably connected to the inner side of the first slider 14. The outer side of the second guide rail 22 is slidably connected to the inner side of the second slider 18.

[0039] The control mechanism 3 includes a controller 30, a first travel switch 31, and a second travel switch 32. The controller 3 is electrically connected to both the first and second travel switches 31, 32, and the controller 30 receives switch signals from both. The first and second travel switches 31, 32 do not require power, are contactless, and maintenance-free, saving maintenance and labor costs. They are also environmentally friendly and cost-effective.

[0040] The second motor can be a forward and reverse motor. When the second motor 15 rotates forward, the second slider 18 drives the rake teeth in the forward direction, cleaning the sludge to the discharge outlet. When the second motor 15 rotates reversely, the second slider 18 drives the rake teeth in the reverse direction, cleaning the sludge to the discharge outlet. The sludge is raked out to the sludge treatment tank in a single reciprocating motion.

[0041] How it works

[0042] The rotation of the first motor 10 drives the first rotating wheel 11, which performs circular motion within its plane. The first rotating wheel 11, the first fixed rod 12, the first telescopic rod 13, and the first slider 14 form a slider-crank mechanism. The rotation of the first rotating wheel 11 drives the first fixed rod 12 to perform curvilinear motion within its plane. The motion of the first fixed rod 12 drives the first telescopic rod 13 to drive the first slider 14 to reciprocate on the first guide rail 21. Simultaneously, the rotation of the second motor 15 drives the second rotating wheel 16, which performs circular motion within its plane. The second rotating wheel 16, the second fixed rod 17, the second telescopic rod, and the second slider form another slider-crank mechanism. The rotation of the second rotating wheel 16 drives the second fixed rod 17 to perform curvilinear motion within its plane. The second fixed rod 17 drives the second telescopic rod 18 to drive the second slider 19 to reciprocate on the second guide rail 22. The first slider 14 and the second slider 19 together drive the rake rod 41 to reciprocate between the first guide rail 21 and the second guide rail 22. During the rightward movement, the first travel switch 31 and the second travel switch simultaneously sense the distance between the rake rod 41 and themselves. When the rake rod 41 approaches the first travel switch 31 and the second travel switch 32, the first travel switch 31 and the second travel switch 32 send a stop signal to the controller 30, and the controller 30 transmits the stop signal to the first motor 10 and the second motor 15 respectively. The first motor 10 and the second motor 15 stop running, the rake rod 41 stops moving, and the rake teeth 44 on the rake rod 41 rake the sludge out to the discharge outlet at the right end.

[0043] At this time, after receiving the signal that the first motor 10 and the second motor 15 stop running, the controller 30 sends a reverse instruction information to the first motor 10 and the second motor 15, and at the same time controls the reversing groove 42 on the rake rod 41 to reverse the position of the rake teeth. The first motor 10 and the second motor 15 start to reverse, respectively driving the first slider 14 and the second slider 19 to move left. During the leftward movement, the first travel switch 31 and the second travel switch 32 sense the distance between the rake rod 41 and themselves in real time. When the rake rod 41 approaches the first travel switch 31 and the second travel switch 32, the first travel switch 31 and the second travel switch 32 send a stop signal to the controller 30. The controller 30 transmits the stop signal to the first motor 10 and the second motor 15 respectively. The first motor 10 and the second motor 15 stop running, the rake rod 41 stops moving, and the rake teeth 44 on the rake rod 41 rake out the sludge to the discharge outlet at the left end. The sludge is raked out to the discharge outlet in one reciprocating motion cycle, achieving the purpose of quickly raking out the sludge.

[0044] The present invention utilizes a first motor 10 and a second motor 15 to drive a first slide block 14 and a second slide block 19, respectively, to drive a rake rod 41 to reciprocate on a guide rail mechanism 2, thereby raking the sludge to a discharge outlet. A controller 30 controls a switching groove 42 to switch the position of the rake teeth, thereby achieving the purpose of raking out the sludge in one go, saving time in raking out the sludge and improving work efficiency.

[0045] This specific embodiment is merely an explanation of the invention and is not a limitation of the invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as they are within the scope of protection of the invention, they are protected by patent law.
