Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an environmentally friendly treatment device and method for sludge in a sewage treatment process. Background Art

[0002] In the process of sewage treatment, it is generally necessary to dry the reaction sedimentation sludge with high water content accumulated at the bottom of the sedimentation tank so that the dried sludge can be discharged into the environment. At present, the more commonly used sludge drying method is physical drying, that is, by placing a certain amount of sludge in a closed space and squeezing it to reduce the effective volume of the closed space (the volume of the internal space for storing sludge), and squeeze out a large amount of water mixed in the sludge, and filter it through a filter. This method has the advantages of low cost, safety and reliability.

[0003] Patent application CN118459048B discloses a sewage treatment sludge compression treatment device, the technical solution of which is as follows: it includes a base, the top outer wall of the base is fixedly connected to a sludge extraction cylinder, and a sludge extraction mechanism is arranged inside the sludge extraction cylinder, one end of the sludge extraction cylinder is an open structure, the side of the open end of the sludge extraction cylinder is fixedly connected to a fixed block, and the outer wall of one side of the fixed block is rotatably connected to a turntable, the outer wall of the side of the turntable is provided with four circular holes evenly distributed in an annular pattern, the inner wall of the side of the circular hole is fixedly connected to a compression cylinder, and the inner wall of the side of the compression cylinder is slidably connected to a filter frame. In this invention, when the compression cylinder on one side of the sludge extraction cylinder is filled with compressed sludge, the rotation of the turntable will drive the compression cylinder to move to one side of the pushing mechanism, and then the pushing mechanism will clean out the sludge in the compression cylinder, and at the same time, the compression cylinder on the other side will move to one side of the sludge extraction cylinder to continue compressing the sludge, thereby improving the compression efficiency.

[0004] However, the above technology often has the following defects: after the sludge in the compression cylinder is compressed and discharged, the sludge tends to accumulate in the same position of the collection box. As the sludge continues to accumulate, if it is not cleaned in time, the accumulated sludge may block the discharge end of the compression cylinder, causing the sewage outlet of the equipment to be blocked, affecting the subsequent sludge discharge and compression operation. When the sludge is accumulated too high, it will cause equipment blockage and poor sewage discharge, forcing operators to manually guide and clean, increasing the labor intensity and reducing work efficiency. In addition, manual cleaning not only increases the operating cost, but also affects the continuity and stability of production.

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1: Figures 1 to 7 As shown, an environmentally friendly treatment device for sludge in a sewage treatment process according to an embodiment of the present invention comprises a filter tank 1 and a collecting barrel 11, wherein a sludge treatment component is provided between the filter tank 1 and the collecting barrel 11, and the sludge is compressed into a mud cake by the sludge treatment component;

[0039] The sludge treatment assembly includes a motor 15, a rotating shaft 16 is fixed to the output end of the motor 15, a housing 7 is fixed to the top of the rotating shaft 6, a motor 29 is fixed to the top of the housing 7, a rotating shaft 28 is rotatably mounted on the side of the housing 7, a filter cartridge 4 is fixed to one end of the rotating shaft 8 through a connecting block 24, a cloth bag 21 is installed in the middle of the filter cartridge 4, the other end of the rotating shaft 28 extends to the inside of the housing 7, and the end of the rotating shaft 28 is connected to the output end of the motor 29 through a bevel gear set;

[0040] It also includes a driving assembly, through which the collecting barrel 11 is driven to rotate intermittently, the driving assembly includes a toothed disc 13, the toothed disc 13 is rotatably mounted on the side of the filter tank 1 through a mounting frame, the rotating shaft 16 movably penetrates the toothed disc 13, a toothed ring 17 meshing with the toothed disc 13 is fixed on the outer wall of the collecting barrel 11, a ratchet 14 is fixed on the inner wall of the inner cavity of the toothed disc 13, a rotating disc 15 is fixed on the rotating shaft 16, and a clamping block 16 clamped with the ratchet 14 is movably mounted on the side wall of the rotating disc 15 through a torsion spring;

[0041] A bracket 2 is fixed above the filter tank 1, a hydraulic cylinder 3 is fixed on the bracket 2, and a pressing plate 20 is fixed on the telescopic end of the hydraulic cylinder 3;

[0042] During operation, the sludge at the bottom of the sedimentation tank is pumped out by the sludge pump, and an appropriate amount of sludge is transported to the cloth bag 21 in the middle of the filter cartridge 4 through the conveying hose. The sludge pump is then stopped, and the water in the sludge automatically seeps out of the cloth bag 21 under the influence of its own weight. The hydraulic cylinder 3 then drives the pressing plate 20 to move down along the filter cartridge 4 into the cloth bag 21, and the pressing plate 20 is used to squeeze the sludge to further squeeze out the water in the sludge. The sewage falls into the filter tank 1 below and is collected, thereby preventing sewage leakage and polluting the surrounding environment. The sludge is squeezed into a mud cake, and then the hydraulic cylinder 3 drives the pressing plate 20 to move up to the top of the filter cartridge 4. The motor 5 then drives the rotating shaft 6 to rotate, and the rotating shaft 6 passes through the housing 7 and the second shaft 8 drive the filter cartridge 4 to rotate horizontally 180 degrees, so that the filter cartridge 4 rotates to the top of the collection bucket 11, and then the motor 2 9 and the bevel gear group drive the shaft 1 6 and the filter cartridge 4 to rotate vertically 180 degrees, so that the filter cartridge 4 flips over, and then the opening of the cloth bag 21 is downward, and the mud cake in the cloth bag 21 automatically falls into the collection bucket 11 below under the action of gravity, so that the mud cake can be collected. The dehydrated sludge block is usually rich in organic matter and nutrients (such as nitrogen, phosphorus, potassium, etc.), which can be used as a soil conditioner or organic fertilizer. The treated sludge will not cause harm to the environment and is more environmentally friendly. At the same time, it can increase the organic matter content of the soil and improve the structure and water retention capacity of the soil;

[0043] In addition, the motor 5 drives the rotating shaft 6 to rotate, and at the same time drives the rotating disk 15 and the clamping block 16 to rotate synchronously. The clamping block 16 is engaged with the ratchet 14 to drive the toothed disk 13 to rotate. The toothed disk 13 cooperates with the gear ring 17 to drive the collecting barrel 11 to rotate. When the mud blocks fall off, the motor 5 is controlled to drive the rotating shaft 6 to rotate in the opposite direction, and then the filter cartridge 4 is driven to reset to the initial position for the next processing step. During the process of the motor 5 driving the rotating shaft 6 to rotate in the opposite direction, the clamping block 16 passes through the ratchet 14 and will not drive the ratchet 14 and The toothed disc 13 rotates, and the collecting bucket 11 remains stationary at this time, so that the collecting bucket 11 can be intermittently rotated at a certain angle. By controlling the size of the toothed disc 13 and the gear ring 17, the rotation angle of the collecting bucket 11 is controlled, so that the mud cakes fall into different positions in the collecting bucket 11 in sequence, and the mud cakes are stacked layer by layer in the collecting bucket 11, so that more mud cakes can be stacked, and there is no need to manually sort the mud cakes, so as to avoid the mud cakes from piling up too high at the same position, affecting subsequent work, and there is no need to frequently replace the collecting bucket 11, thereby improving work efficiency;

[0044] Two filter cartridges 4 are provided, symmetrically distributed on both sides of the housing 7, and two filter cartridges 4 and cloth bags 21 are used to work together. The cloth bags 21 on both sides rotate in opposite directions through the bevel gear set. When the filter cartridge 4 and cloth bag 21 on one side are used to compress the mud cake, the cloth bag 21 on the other side is in an unloaded state. Then the motor 1 5 drives the cloth bag 21 filled with mud cake to rotate to the top of the collection bucket 11, and then the motor 2 9 drives the filter cartridge 4 to rotate, so that the mud cake in the cloth bag 21 is turned over and poured out, and then the motor is controlled to rotate in the opposite direction so that the inner cloth bag 21 can be in the filter cartridge 4. The cloth bag 21 is flipped over, and the residue remaining on the side wall is shaken off by bending and deforming the cloth bag 21, so that the cloth bag 21 maintains good water filtering performance, and the cloth bag 21 can be flipped over multiple times to achieve a better residue shaking-off effect; the unloaded cloth bag 21 on the other side rotates synchronously, and the cloth bag 21 is flipped over to further improve the residue removal effect; after the residue shaking-off work is completed, mud can be injected into the unloaded cloth bag 21 on the other side, and then the mud block compression operation is performed, and then the filter cartridges 4 on both sides are swapped, so that continuous work can be achieved to improve work efficiency.

[0045] A support frame 25 for supporting the rotating shaft 2 8 is fixed to the side wall of the shell 7, and a tapping assembly is arranged below the support frame 25, and the tapping assembly includes a fixed block 26, and a tapping rod 27 is slidably installed in the middle of the fixed block 26, and a spring 28 is fixed on the side wall of the fixed block 26, and the end of the spring 28 away from the fixed block 26 is connected and fixed to the tapping rod 27, and a magnetic block 22 is fixed to the end of the tapping rod 27 close to the rotating shaft 1 6, and an iron plate 23 is fixed to the top of the filter tank 1 and adjacent to the rotating shaft 1 6; during operation, when the filter cartridges 4 on both sides are respectively facing the filter tank 1 and the collecting barrel 11, the magnetic block 22 and the iron plate 23 are opposite to each other, and are adsorbed on the iron plate 23 by the magnetic block 22. The knocking rod 27 moves toward the magnetic block 22, and the spring 28 is stretched. When the motor 5 drives the rotating shaft 6 and the shell 7 to rotate, the support frame 25 and the lower structure are driven to rotate synchronously through the shell 7, thereby driving the magnetic block 22 to separate from the iron plate 23. At this time, the spring 28 rebounds and resets, driving the knocking rod 27 to move toward the filter cartridge 4. When the spring 28 is in the initial state, there is a gap between the end of the knocking rod 27 and the filter cartridge 4, so that the spring 28 can move back and forth, and then the knocking rod 27 can knock on the side wall of the filter cartridge 4 multiple times. The vibration generated separates the side of the mud cake from the inner wall of the cloth bag 21, so that when the cloth bag 21 is turned over, the mud can be easily poured out, thereby improving the efficiency of dumping the mud.

[0046] A counterweight block 32 is fixed to the bottom of the cloth bag 21; when working, the cloth bag 21 is automatically unfolded by the gravity of the counterweight block 32 for next use. In addition, the flipping rate of the cloth bag 21 can be accelerated. When the cloth bag 21 flips over, the counterweight block 32 quickly drops to the bottom. At this time, the counterweight block 32 provides a downward force to the cloth bag 21, so that the cloth bag 21 is instantly tightened, and then the cloth bag 21 will rebound relatively upward. This process is conducive to breaking off the residue from the side wall of the cloth bag 21, making it convenient to shake off the residue and clean the cloth bag 21.

[0047] A base plate 10 is provided below the collecting barrel 11, and universal wheels 18 are symmetrically fixed to the lower end surface of the collecting barrel 11, and the universal wheels 18 are in contact with the base plate 10. A support rod 19 is rotatably installed in the middle of the base plate 10, and the support rod 19 is movably inserted into a socket opened in the center of the bottom of the collecting barrel 11; when working, the collecting barrel 11 is supported by the universal wheels 18 and the support rod 19, and the collecting barrel 11 can be stably rotatably set on the base plate 10, and the collecting barrel 11 is lifted by the universal wheels 18 and the support rod, so that enough gap is reserved at the bottom of the collecting barrel 11, so that the collecting barrel 11 can be lifted from the bottom to other transfer vehicles by a forklift; in addition, lifting rings (not shown in the figure) can be symmetrically fixed on the top of the collecting barrel 11, so that the empty collecting barrel 11 can be lifted onto the base plate 10 by lifting equipment.

[0048] The bottom of the pressing plate 20 is provided with a groove 29, in which a flap 30 is rotatably installed by a torsion spring, and the top of the groove 29 is provided with a through hole penetrating the pressing plate 20, in the middle of which a connecting pipe 31 is fixed; when working, the conveying hose connected to the outlet end of the sludge pump is fixed on the connecting pipe 31, so that the hose can move synchronously with the pressing plate 20, so as to avoid the hose being scattered and difficult to organize when not in use; in addition, the mud is input into the cloth bag 21 from the connecting pipe 31 and the through hole through the hose, and under the action of the torsion spring, the flap 30 is initially in an open state, and when the through hole is opened, the connecting pipe 31 is opened. When the pressure plate 20 squeezes the mud, the reverse force of the mud causes the flap 30 to cover the middle of the groove 29 to prevent the mud from flowing back into the through hole. At this time, the bottom plate 10 of the pressure plate 20 is a complete plane so that the mud can be compressed into a mud cake. After the compression is completed, the pressure plate 20 is driven upward by the hydraulic cylinder 3, and the flap 30 is driven to rotate outward and open by the torsion spring for use in the next grouting. In addition, when the mud cake is tightly attached to the lower end surface of the pressure plate 20, it may rise together with the pressure plate 20. At this time, the mud cake can be pushed apart from the pressure plate 20 by rotating the flap 30 outward and opening it.

[0049] The two sides of the groove 29 are arranged in the shape of vertical bars; during operation, when the flap 30 covers the middle of the groove 29, there is mud between the flap 30 and the inner wall of the groove 29. By setting the inner wall at the top of the groove 29 in the shape of vertical bars, the contact area between the flap 30 and the inner wall of the groove 29 is reduced, and the adhesion force between the flap 30 and the inner wall of the groove 29 is reduced, thereby preventing the flap 30 from being tightly adhered to the inner wall of the groove 29 and being difficult to open.

[0050] A support plate 33 is fixed on the filter cartridge 4 and below the cloth bag 21; during operation, the support plate 33 supports the bottom of the cloth bag 21 to prevent the pressing plate 20 from squeezing too much force beyond the bearing range of the cloth bag 21 and causing damage to the cloth bag 21.

[0051] A filter screen 12 is fixed on the top of the filter tank 1 ; when working, the filter screen 12 is arranged to filter the sewage seeping out of the bag 21 , and in addition, the residue shaken off from the bag 21 can be collected.

[0052] Embodiment 2: Figure 8 As shown, compared with Example 1, another embodiment of the present invention is as follows: a plurality of groups of mounting holes 34 are symmetrically provided in the middle of the filter cartridge 4, a connecting strip 36 is fixed at a corresponding position on the top of the cloth bag 21, and the connecting strip 36 can pass through the mounting hole 34, and the outer wall of the filter cartridge 4 is provided with a clamp 35 for clamping the connecting strip 36, and notches are provided at both ends of the side edge where the connecting block 24 is connected to the filter cartridge 4, which are adapted to the two ends of the clamp 35, and bolts for clamping the clamp 35 are threadedly connected at both ends of the fixing block 26; when working, the connecting strip 36 on the cloth bag 21 is passed through the mounting hole 34, and then the clamp 35 is inserted into the notch of the connecting block 24 from top to bottom, and the connecting strip 36 protruding from the mounting hole 34 is clamped, and then the clamp 35 is fixed by tightening the bolts, and then the new cloth bag 21 is installed and fixed in the filter cartridge 4; on the contrary, the damaged cloth bag 21 can be quickly removed by removing the bolts and the clamp 35 so as to replace the cloth bag 21.

[0053] like Fig. 9 As shown, a method for environmentally friendly treatment of sludge in a sewage treatment process, which is applicable to the above-mentioned environmentally friendly treatment device for sludge in a sewage treatment process, comprises the following steps:

[0054] S1. Pump out the sludge at the bottom of the sedimentation tank through the sludge pump, and add an appropriate amount of sludge into the bag 21 in the middle of the filter cartridge 4 through the delivery hose, the connecting pipe 31 and the through hole;

[0055] S2, the sludge pump is stopped, and the water contained in the sludge automatically seeps out from the bag 21, and the pressing plate 20 is driven by the hydraulic cylinder 3 to move down into the bag 21, and the water in the sludge is further squeezed out to make the sludge into a mud cake, and then the pressing plate 20 is driven by the hydraulic cylinder 3 to move up to the top of the filter cartridge 4, and the seeping sewage falls into the filter tank 1 below to be collected;

[0056] S3, the motor 15 drives the shaft 16 to rotate, and the shaft 16 drives the filter cartridge 4 to rotate horizontally 180 degrees through the housing 7 and the shaft 2 8, so that the filter cartridge 4 rotates to the top of the collection bucket 11, and then the motor 2 9 and the bevel gear group drive the shaft 16 and the filter cartridge 4 to rotate vertically 180 degrees, pouring out the mud cake in the bag 21, and the mud cake falls into the collection bucket 11 below to be collected, and the sludge treatment work is completed once;

[0057] S4, the motor 5 drives the rotating shaft 6 to rotate, and at the same time drives the rotating disk 15 and the clamping block 16 to rotate synchronously, and the clamping block 16 is engaged with the ratchet 14 to drive the toothed disk 13 to rotate, and the toothed disk 13 and the gear ring 17 cooperate to drive the collecting bucket 11 to rotate, so that the mud cakes will fall at different positions in the collecting bucket 11, so as to stack the mud cakes.

[0058] Working principle: The sludge at the bottom of the sedimentation tank is pumped out by the sludge pump, and an appropriate amount of sludge is transported to the cloth bag 21 in the middle of the filter cartridge 4 through the conveying hose. Then the sludge pump is stopped, and the water in the sludge automatically seeps out of the cloth bag 21 under the influence of its own weight. Then the hydraulic cylinder 3 drives the pressing plate 20 to move down along the filter cartridge 4 into the cloth bag 21. The pressing plate 20 squeezes the sludge to further squeeze out the water in the sludge. The sewage falls into the filter tank 1 below and is collected, avoiding sewage leakage and pollution of the surrounding environment. The sludge is turned into mud cakes through squeezing. , and then the hydraulic cylinder 3 drives the pressing plate 20 to move up to the top of the filter cartridge 4, and then the motor 15 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the filter cartridge 4 to rotate horizontally 180 degrees through the housing 7 and the rotating shaft 2 8, so that the filter cartridge 4 rotates to the top of the collection bucket 11, and then the motor 2 9 and the bevel gear group drive the rotating shaft 16 and the filter cartridge 4 to rotate vertically 180 degrees, so that the filter cartridge 4 flips over, and then the opening of the cloth bag 21 is downward, and under the action of gravity, the mud cake in the cloth bag 21 automatically falls into the collection bucket 11 below, so that the mud cake can be collected;

[0059] In addition, the motor 15 drives the rotating shaft 16 to rotate and drives the rotating disk 15 and the clamping block 16 to rotate synchronously. The clamping block 16 is engaged with the ratchet 14 to drive the toothed disk 13 to rotate. The toothed disk 13 and the gear ring 17 cooperate to drive the collecting bucket 11 to rotate. When the mud block falls, the motor 15 is controlled to drive the rotating shaft 6 to rotate in the opposite direction, thereby driving the filter cartridge 4 to reset to the initial position for the next processing step. During the process of the motor 15 driving the rotating shaft 6 to rotate in the opposite direction, the clamping block 16 passes through the ratchet 14 and will not drive the ratchet 14 and the toothed disk 13 to rotate. At this time, the collecting bucket 11 remains stationary, so that the collecting bucket 11 can be intermittently rotated by a certain angle. By controlling the size of the toothed disk 13 and the gear ring 17, the rotation angle of the collecting bucket 11 is controlled, so that the mud cakes fall into different positions in the collecting bucket 11 in turn, so that more mud cakes can be stacked in the collecting bucket 11. There is no need to manually sort the mud cakes to avoid excessive accumulation of mud cakes in the same position, which affects subsequent work. There is no need to frequently replace the collecting bucket 11, thereby improving work efficiency.
