Description

Technical Field

[0001] The present application relates to the technical field of sludge treatment devices, and in particular to a treatment device and method for organic sludge. Background Art

[0002] Organic sludge refers to sludge mainly composed of organic matter. In order to reduce the organic matter content in organic sludge and reduce its putrefaction and odor, aerobic digestion of organic sludge is usually required to utilize aerobic microorganisms to decompose the organic matter in the sludge, making the sludge stable and harmless. Therefore, it is necessary to add oxygen to the organic sludge to increase the oxygen content in the sludge so that the aerobic microorganisms in the sludge can decompose the organic matter. For example, the Chinese patent with the publication number CN113845214A in the related art proposes an aeration device for treating aerobic granular sludge, which has the advantages that the rotating frame is rotatably connected to the mounting frame through the first shaft rod, the cylinder body is located between the two second shaft rods and is powered by the first motor, the cylinder body is driven to rotate by the rotation of the rotating arm, and in cooperation with the forward and backward swing conversion of the rotating frame, a dead-angle-free aeration effect is provided.

[0003] When adding oxygen to organic sludge, bubbles are usually generated, pushing the sludge particles to the water surface, causing the sludge to float, resulting in an increase in suspended solids in the effluent from the sludge, deteriorating the effluent quality, and increasing the difficulty of subsequent sludge treatment. Therefore, when adding oxygen to organic sludge, an antifoaming agent also needs to be added to quickly destroy the foam generated by aeration while aerating the organic sludge, ensuring that oxygen can be fully dissolved in the sludge, accelerating the sludge treatment speed, and improving the effluent quality.

[0004] Regarding the above related technology, the inventor believes that there are the following defects: Currently, the methods of adding oxygen and antifoaming agent to organic sludge usually directly use an aerator to input oxygen into the sludge and directly pour the antifoaming agent into the sludge, which is not convenient for controlling the oxygen input amount and gas supply speed according to the dissolved oxygen concentration of the organic sludge and the amount of organic sludge treated. Furthermore, the input amount and input speed of the antifoaming agent cannot be controlled according to the oxygen input amount and input speed. When the dissolved oxygen concentration of organic sludge is too low, if the oxygen supply is insufficient, it will lead to a decrease in microbial activity and a reduction in the decomposition efficiency of organic matter, resulting in poor sludge stability, triggering anaerobic conditions, and generating odors and harmful gases; when the amount of organic sludge treated is too small and the oxygen supply speed is too fast, it will lead to an increase in energy consumption and operating costs. At the same time, it will also cause the sludge to become fragmented, increase the generation of foam, and increase the difficulty of subsequent sludge treatment. Summary of the Invention

[0005] In order to solve the problem that the sludge treatment device is not convenient to control the oxygen input amount and the gas transmission speed according to the dissolved oxygen concentration of the organic sludge and the amount of organic sludge treatment, and thus cannot control the input amount and the gas transmission speed of the defoaming agent according to the oxygen input amount and the input speed, the present application provides a treatment device and a treatment method for organic sludge.

[0006] The treatment device and the treatment method for organic sludge provided by the present application adopt the following technical solutions: A treatment device for organic sludge includes a sludge tank, a plurality of oxygen heads and a plurality of discharge heads arranged on the sludge tank, and a weight detection component and a dissolved oxygen detection component for detecting the weight and the dissolved oxygen concentration of the sludge; The weight detection component includes a lifting plate arranged in the sludge tank, an oxygen cylinder and a discharge cylinder fixed on the sludge tank, a piston frame movably arranged on the oxygen cylinder, a feeding plate movably arranged on the discharge cylinder, a lifting member for driving the piston frame to lift, a translation member for driving the feeding plate to translate, and an adjusting member for synchronously adjusting the driving speeds of the lifting member and the translation member; The dissolved oxygen detection component includes two stirring cylinders rotatably arranged in the sludge tank, a plurality of swing rods respectively arranged on the two stirring cylinders, air outlet plates respectively arranged on the plurality of oxygen heads, discharge plates respectively arranged on the plurality of discharge heads, an air outlet member for driving the air outlet plates to translate, a discharge member for driving the discharge plates to translate, a synchronizing member for synchronously driving the air outlet member and the discharge member, and a rotating member for synchronously rotating the two stirring cylinders; A driving member for telescopically driving the plurality of oxygen heads and swingably driving the plurality of swing rods is further arranged on the sludge tank; The lifting member includes a bidirectional screw rod rotatably arranged on the piston frame, an oxygen pipe and a branch pipe communicated with the oxygen cylinder, and an oxygen tank arranged on the oxygen pipe, and the bidirectional screw rod is in threaded connection with the piston frame.

[0007] By adopting the above technical solution, when the dissolved oxygen concentration of organic sludge is too low during treatment, the activity of microorganisms will decrease, the decomposition of organic matter will be incomplete, and the viscosity of sludge will increase. When the dissolved oxygen concentration is too high, the metabolic activity of microorganisms will be accelerated, the decomposition of organic matter will be promoted, and the viscosity of sludge will be reduced. When the dissolved oxygen concentration of organic sludge is too high, if the oxygen supply is excessive, it will lead to increased energy consumption and inhibit the activity of some oxygen-sensitive microorganisms, resulting in a decrease in the sludge treatment effect. If the oxygen supply in organic sludge is too high, the defoaming agent supply will be insufficient and will not be able to effectively inhibit the formation and aggregation of foam, reducing the effect of sludge treatment. The sludge treatment efficiency is reduced; if the oxygen supply in the organic sludge is too small, the defoaming agent supply is excessive, which will lead to a waste of resources; when the organic sludge treatment volume is too large and the oxygen supply speed is too slow, the microorganisms in the sludge cannot obtain enough oxygen to carry out normal physiological activities, and the treatment time is prolonged; when the oxygen supply speed is too fast and the defoaming agent supply speed is too slow, the microorganisms in the sludge will be over-oxidized and a large amount of foam will be generated; when the oxygen supply speed is too slow and the defoaming agent supply speed is too fast, it will lead to a waste of resources, increase operating costs, and cause insufficient dissolved oxygen concentration in the sludge; The weight detection component can detect the weight of the sludge in the sludge box, the dissolved oxygen detection component can detect the viscosity of the sludge in the sludge box, and can detect the dissolved oxygen concentration of the sludge. The gas outlet can put oxygen into the sludge box to aerobically treat the sludge, and at the same time, it can evenly put oxygen into multiple positions of the sludge, and the oxygen supply volume can be controlled according to the dissolved oxygen concentration of the sludge. The discharge component can put defoaming agent into the sludge box to defoam the sludge, and at the same time, it can evenly put defoaming agent into multiple positions of the sludge, and the input volume of defoaming agent can be controlled according to the oxygen supply volume. The synchronization component can make the gas outlet component and the discharge component degas and discharge synchronously, so that oxygen can be put into the sludge while the defoaming agent can defoam the sludge, and try to avoid bubbles when oxygen is drawn into the sludge. The rotating component can stir the sludge in the sludge box to ensure the effect of sludge and defoaming agent on aerobic treatment of the sludge. The lifting part can adjust the speed at which oxygen enters the sludge, and can control the oxygen gas transmission speed according to the amount of sludge treated, so as to maintain the optimal oxygen gas transmission speed according to the amount of sludge treated. The translation part can adjust the speed at which the defoaming agent enters the sludge, and can control the input speed of the defoaming agent according to the amount of sludge treated, so as to maintain the optimal input speed of the defoaming agent according to the amount of sludge treated. The adjusting part can adjust the speed of the lifting part and the translation part drive, and can synchronously control the speed of the lifting part and the translation part drive according to the amount of sludge treated, so as to avoid waste of resources and ensure the sludge treatment effect. The driving part can open the corresponding number of oxygen heads and discharge heads according to the amount of sludge treated, so as to avoid waste of oxygen and defoaming agent; when the bidirectional screw rotates, it can drive the piston rack to move up and down in the oxygen cylinder, and can push the oxygen in the oxygen tube through the oxygen cylinder to the sub-rack pipe and multiple oxygen heads, so as to aerobically treat the sludge in the sludge box.

[0008] Optionally, the translation member includes a cam rotatably disposed on the discharge cylinder, a rotating rod fixed to the cam, a telescopic spring fixed to the feeding plate, a driving wheel fixed to the bidirectional screw, a driven wheel fixed to the rotating rod, a conveyor belt drivingly disposed between the driving wheel and the driven wheel, a feed pipe and a special-shaped pipe communicating with the discharge cylinder, and a storage tank disposed on the feed pipe. The telescopic spring is fixedly connected to the discharge cylinder, and the cam is movably attached to the feeding plate.

[0009] By adopting the above technical solution, the translation member can transport the defoamer into the sludge tank to defoam the sludge. When the bidirectional screw rotates, it can successively drive the driving wheel, the conveyor belt, the driven wheel, the rotating rod and the cam to rotate. Cooperating with the elastic force of the telescopic spring, it can push the feeding plate to move left and right frequently in the discharge cylinder, and can push the defoamer in the feed pipe through the discharge cylinder into the special-shaped pipe and multiple discharge heads, so as to defoam the sludge while oxygen aerates the sludge, and enhance the effect of aerobic treatment of the sludge by oxygen.

[0010] Optionally, the adjusting member includes a movable rod fixed to the right stirring cylinder, an inclined strip plate fixed to the lifting plate, a third spring fixed to the sludge tank, an adjusting strip fixed to the third spring, a first half-wheel and a first spring fixed to the movable rod, a third half-wheel and a second spring fixed to the bidirectional screw, a second half-wheel slidably disposed on the movable rod, a fourth half-wheel slidably disposed on the bidirectional screw, and a speed-regulating belt drivingly disposed between the first half-wheel, the second half-wheel, the third half-wheel and the fourth half-wheel.

[0011] By adopting the above technical solution, the adjusting member can synchronously drive the lifting member and the translation member, and can control the driving speeds of the lifting member and the translation member. When the movable rod rotates, it can successively drive the first half wheel, the second half wheel, the first spring, the speed regulating belt, the third half wheel, the second spring, the fourth half wheel and the bidirectional screw to rotate. When the lifting plate moves up and down, it will drive the inclined strip plate to lift and lower, and then drive the adjusting strip to move, so that the third spring is in a compressed state, which can drive the fourth half wheel to move in cooperation with the elastic force of the second spring, enabling the fourth half wheel to slide on the bidirectional screw. When the fourth half wheel moves, it can adjust the position of the speed regulating belt between the third half wheel and the fourth half wheel. At the same time, when the speed regulating belt is adjusted, in cooperation with the elastic force of the first spring, it will also drive the second half wheel to slide on the movable rod, and can adjust the position of the speed regulating belt between the third half wheel and the fourth half wheel. By the different transmission ratio positions of the speed regulating belt between the first half wheel and the second half wheel and the third half wheel and the fourth half wheel, the rotational speeds of the bidirectional screw and the cam can be adjusted. The lower the lifting plate drives the inclined strip plate to descend, the more the adjusting strip and the fourth half wheel are pushed to move, the smaller the transmission ratio of the speed regulating belt between the third half wheel and the fourth half wheel, and the faster the rotational speeds of the bidirectional screw and the cam, which can increase the speed of the piston frame pushing oxygen in the oxygen cylinder and increase the speed of the feeding plate pushing the defoamer in the discharge cylinder, and can control the conveying speeds of oxygen and the defoamer according to the quantity of sludge treatment.

The connecting springs are fixedly connected with the discharging plate, the connecting rod is in movable contact with the air outlet plate, and a second one-way solenoid valve is fixedly connected to each of the plurality of discharging heads.

[0015] By adopting the above technical solution, the discharging member can open and close the discharging heads. When the air outlet member drives a plurality of air outlet plates to move respectively, it can drive a plurality of connecting rods and a plurality of discharging plates to move respectively, and in cooperation with a plurality of connecting springs, it can open and close a plurality of discharging heads frequently, so that a plurality of discharging heads can put the defoamer into the sludge tank for defoaming treatment of the sludge.

[0016] Optionally, the synchronizing member includes tension springs respectively fixed to a plurality of swing rods and detection blocks respectively fixed to the plurality of tension springs. The detection blocks are movably hinged to the swing rods, and the detection blocks are movably fitted with the wedge blocks.

[0017] By adopting the above technical solution, the synchronizing member can detect the dissolved oxygen concentration of the sludge at different height positions in the sludge tank. When the detection block stirs the sludge, the angle of the detection block on the swing rod can be adjusted in cooperation with the tension spring, and the viscosity of the sludge can be detected. When the viscosity of the sludge is relatively high, the resistance to the detection block is greater, and the swing angle of the detection block on the swing rod is greater. When the plurality of detection blocks rotate, they will respectively push the corresponding plurality of wedge blocks to move. The larger the included angle of the detection blocks on the swing rod, the more positions where the detection blocks contact the wedge blocks during rotation, and the larger the opening gaps in the oxygen heads and the discharge heads. The gas outlet amounts of oxygen and defoamer and the discharge amounts are also larger. The gas outlet amounts of oxygen and defoamer and the discharge amounts can be controlled according to the different dissolved oxygen concentrations of the sludge, and the air outlet pipe and the discharge pipe can be opened and closed synchronously.

The movable rod is fixedly connected to the output shaft of the electric motor.

[0019] By adopting the above technical solution, the rotating member can stir the sludge in the sludge tank, so that oxygen and defoamer can be evenly mixed with the sludge. The electric motor can drive the movable rod, the transmission wheel, the transmission belt, the passive wheel, the rotating rod, the two stirring cylinders, the plurality of swing rods and the plurality of detection blocks to rotate in sequence, so as to stir the sludge in the sludge tank, and further enhance the effect of aerobic treatment of the sludge by oxygen and defoamer.

[0020] Optionally, the driving member includes a plurality of measuring springs fixed to the sludge tank, double-sided wedge blocks respectively fixed to a plurality of oxygen heads, telescopic hoses respectively communicated with the plurality of oxygen heads, return springs and induction switches respectively fixed to the plurality of double-sided wedge blocks, torsion springs respectively fixed to the plurality of swing rods.

[0021] By adopting the above technical solution, the driving member can turn on a specified number of oxygen heads and discharge heads according to the amount of sludge treatment. When the weight of the sludge drives the lifting plate to rise and fall in cooperation with the elastic force of multiple measuring springs, it will contact the induction switch on the double-sided wedge block, and can turn on the first one-way solenoid valve and the second one-way solenoid valve on the oxygen head and discharge head at the corresponding height, so that the oxygen heads and discharge heads at the corresponding height are turned on. It is possible to turn on a specified number of oxygen heads and discharge heads according to the amount of sludge treatment. At the same time, when the lifting plate rises and falls, it can squeeze and push the swing rod and double-sided wedge block at the corresponding height. The torsion spring can make the swing rod swing. The return spring and the telescopic hose make the double-sided wedge block and the oxygen head telescopic. When the lifting plate moves to the corresponding position, the thrust of the lifting plate and the torsion force of the torsion spring can store the swing rod and the detection block. With the elastic force of the return spring and the telescopic hose, the double-sided wedge block and the oxygen head can be squeezed and stored, avoiding obstacles caused by the swing rod and the double-sided wedge block when the lifting plate rises and falls.

[0022] Optionally, there are four groups of the multiple telescopic hoses, multiple oxygen heads, multiple double-sided wedge blocks, multiple air outlet plates, multiple wedge-shaped blocks, multiple fixed grooves, multiple discharge heads, multiple discharge plates, multiple swing rods, multiple detection blocks and multiple storage grooves. The four groups of telescopic hoses, four groups of oxygen heads, four groups of double-sided wedge blocks, four groups of air outlet plates, four groups of wedge-shaped blocks, four groups of fixed grooves, four groups of discharge heads, four groups of discharge plates, four groups of swing rods, four groups of detection blocks and four groups of storage grooves are arranged at equal distances. The multiple double-sided wedge blocks and the multiple swing rods are both in active contact with the lifting plate.

[0023] By adopting the above technical solution, when the two stirring cylinders drive the multiple swing rods and the multiple detection blocks to rotate respectively, the multiple detection blocks can respectively push the corresponding multiple wedge-shaped blocks to move, and frequently open and close the multiple oxygen heads and multiple discharge heads on the sludge tank respectively. Oxygen heads and discharge heads are arranged at different height positions on the sludge tank, and oxygen and defoaming agent can be conveyed to different positions in the sludge tank, so as to facilitate the aeration and defoaming treatment of the sludge at different height positions in the sludge tank by the sludge tank and the defoaming agent.

[0024] A method for treating organic sludge includes the following steps: S1. Pour the sludge into the sludge tank. The weight of the sludge drives the lifting plate to move downward to detect the amount of sludge treatment. According to the amount of sludge, a specified number of oxygen heads and discharge heads can be turned on to spray oxygen and defoaming agent, which can be evenly sprayed on different positions of the sludge, and aerobic and defoaming treatment can be carried out on the sludge at different height positions; S2. When the motor drives the multiple swing rods and the multiple detection blocks to rotate, the sludge can be stirred, so that the oxygen and defoaming agent are evenly mixed with the sludge. When the lifting plate rises and falls, it can control the speed of the piston frame moving up and down. The more sludge there is, the faster the oxygen and defoaming agent are transported; S3. When multiple detection blocks rotate, the dissolved oxygen concentration at different heights of the sludge can be detected. When the multiple detection blocks rotate, the moving ranges of multiple air outlet plates and multiple discharge plates can be respectively controlled according to the different viscosities of the sludge at different heights. The lower the dissolved oxygen concentration of the sludge, the more oxygen and defoamer are added.

[0025] By adopting the above technical solution, the input amount and input speed of oxygen can be controlled according to the dissolved oxygen concentration of the organic sludge and the amount of organic sludge treated. The input amount and input speed of the defoamer can be controlled according to the input amount and input speed of oxygen, and the effect of aerobic treatment of the sludge by oxygen and defoamer can be ensured.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Pour the sludge into the sludge tank. The driving part cooperates with the lifting plate to detect the amount of sludge treated. The lifting part can evenly spray oxygen at different positions of the sludge, so as to facilitate aerobic treatment of the sludge at different heights in the sludge tank, and try to avoid different dissolved oxygen concentrations at different heights of the sludge, which can improve the dissolved oxygen concentration of the sludge and strengthen the effect of aerobic treatment of the sludge. The translation part can evenly spray the defoamer at different positions of the sludge while the sludge at different heights is undergoing aerobic treatment, and can carry out defoaming treatment on the sludge at different heights, avoiding the generation of bubbles when multiple oxygen heads add oxygen to different positions of the sludge, and reducing the disadvantages and interference caused by oxygen to the sludge; 2. The rotating part can stir the sludge, and can evenly mix oxygen and defoamer with the sludge, which can further strengthen the effect of aerobic treatment of the sludge by oxygen and defoamer. The adjusting part can control the conveying speed of oxygen and defoamer according to the amount of sludge treated. The more sludge there is, the faster the conveying speed of oxygen and defoamer. It can avoid the increase in energy consumption caused by too fast oxygen supply speed when the amount of organic sludge treated is too small, so as to ensure that the microorganisms in the sludge obtain enough oxygen for normal physiological activities, avoid the generation of foam in the sludge, and reduce the difficulty of subsequent treatment of the sludge; 3. The rotating parts cooperate with the synchronous parts to detect the viscosity of the sludge at different heights, and the dissolved oxygen concentration of the sludge. Cooperating with the gas outlet and the material outlet, the amount of oxygen and defoamer added can be accurately controlled according to the dissolved oxygen concentration of the sludge at different heights in the sludge box. The oxygen and defoamer can be delivered to different positions in the sludge box so that the sludge box and the defoamer can aerate and defoam the sludge at different heights in the sludge box, thereby improving the dissolved oxygen concentration of the sludge and avoiding the aeration and defoaming of the sludge at different heights as much as possible. The foaming effects are different, preventing the unstable aerobic treatment effect of sludge and poor defoaming effect, ensuring the effect of oxygen and defoaming agent on sludge treatment, the driving part cooperates with the lifting plate to open a specified number of oxygen heads and discharge heads according to the amount of sludge treatment, avoiding excessive opening of the oxygen heads and discharge heads to cause waste of oxygen and defoaming agent, so as to ensure that the sludge is treated with the optimal amount of oxygen and defoaming agent, and avoid excessive or insufficient input of oxygen and defoaming agent, which can not only ensure the effect of sludge treatment but also avoid waste of oxygen and defoaming agent.

[0041] The sludge box 1 is connected with a mud inlet pipe valve and an exhaust pipe, and a purifier is provided on the exhaust pipe. A mud discharge hose 50 is fixedly connected to the lifting plate 10, and a control valve is fixedly installed on the mud discharge hose 50. The end of the mud discharge hose 50 away from the lifting plate 10 passes through the lifting plate 10 and the sludge box 1 in sequence and extends to the outside of the sludge box 1. The organic sludge to be treated can be poured into the sludge box 1 for treatment through the mud inlet pipe valve, and the treated sludge in the sludge box 1 can be released through the mud discharge hose 50 by adjusting the control valve. At the same time, the mud discharge hose 50 has a telescopic effect when the lifting plate 10 is lifted and lowered. The exhaust gas in the sludge box 1 can be sucked in through the exhaust pipe through the purifier, and then the purifier can purify the treated exhaust gas to prevent the exhaust gas generated during the sludge treatment from polluting the air.

[0042] The implementation principle of the organic sludge treatment device in the embodiment of the present application is as follows: (1) When the sludge is poured into the sludge box 1, it will accumulate on the lifting plate 10. The weight of the sludge can be detected by cooperating with multiple measuring springs 12. The more sludge there is on the lifting plate 10, the greater the pressure on the multiple measuring springs 12, and the more the lifting plate 10 will drop. When the lifting plate 10 moves, it will drive the inclined strip plate 11 to move, so the amount of sludge can be detected; (2) The oxygen tank and the storage box are opened. The oxygen in the oxygen tank can be put into multiple oxygen heads 8 through the oxygen pipe, oxygen cylinder 3, branch pipe 4 and multiple telescopic hoses 7. The multiple oxygen heads 8 and multiple discharge heads 9 are respectively arranged at different heights on the sludge box 1, so that the oxygen is evenly sprayed at different positions of the sludge, so that the oxygen can be aerobically treated on the sludge at different heights, and the dissolved oxygen concentration of the sludge at different heights can be avoided as much as possible, thereby improving the dissolved oxygen concentration of the sludge; (3) The defoamer in the storage tank can be put into multiple discharge heads 9 through the feed pipe, the discharge cylinder 2 and the special-shaped pipe 5 respectively, so that while the oxygen is used for aerobic treatment of the sludge, the defoamer can defoam the sludge at different height positions, avoiding the generation of bubbles while the multiple oxygen heads 8 add oxygen to different positions of the sludge, and reducing the disadvantages and interferences caused by oxygen to the sludge; (4) The motor 6 can drive the movable rod 17, the driving wheel 13, the transmission belt 14, the driven wheel 15, the rotating rod 16, the two stirring cylinders 18, the multiple swing rods 37 and the multiple detection blocks 38 to rotate in sequence, and then the sludge in the sludge tank 1 can be stirred. By stirring the sludge, the oxygen and the defoamer can be evenly mixed with the sludge; (5) When the lifting plate 10 moves up and down, it can squeeze and push the corresponding swing rod 37 and the double-sided wedge block 40. The torsion spring can make the swing rod 37 have a swinging effect, and the return spring 39 and the telescopic hose 7 can make the double-sided wedge block 40 and the oxygen head 8 have a telescopic effect. When the lifting plate 10 moves to the corresponding position, the thrust of the lifting plate 10 moving up and down and the torque of the torsion spring can move the swing rod 37 and the detection block 38 into the corresponding storage grooves. When the lifting plate 10 moves upward, the swing rod 37 can swing upward, and when the lifting plate 10 moves downward, the swing rod 37 can swing downward. At the same time, the thrust of the lifting plate 10 moving up and down and the elasticity of the return spring 39 and the telescopic hose 7 can move the double-sided wedge block 40 and the oxygen head 8 into the corresponding fixing grooves, avoiding the lifting plate 10 being blocked by the swing rod 37 and the double-sided wedge block 40 during lifting, so as to ensure the effect of the lifting plate 10 on detecting the sludge volume; (6) When the bidirectional screw 31 rotates, it can sequentially drive the driving wheel 27, the conveyor belt 28, the driven wheel 29, the rotating rod 30 and the cam 33 to rotate, and the elastic force of the telescopic spring 35 can push the feeding plate 34 to move left and right, so that the defoaming agent in the feed pipe can be pushed into the special-shaped tube 5 and the multiple discharge heads 9 through the discharge barrel 2. When the movable rod 17 rotates, it can sequentially drive the first half wheel 32, the second half wheel 21, the first spring 22, the speed regulating belt 23, the third half wheel 26, the second spring 25, the fourth half wheel 24 and the bidirectional screw 31 to rotate, and then drive the piston frame 36 to move up and down, so that the defoaming agent in the feed pipe can be pushed into the special-shaped tube 5 and the multiple discharge heads 9 through the discharge barrel 2. The oxygen in the oxygen tube is pushed into the branch pipe 4, multiple telescopic hoses 7 and multiple oxygen heads 8 through the oxygen cylinder 3. When the lifting plate 10 moves up and down, it also drives the inclined strip plate 11 to move up and down, thereby driving the adjustment strip 20 to move, so that the third spring 19 is in a compressed state. The adjustment strip 20 can drive the fourth half wheel 24 to move, and cooperate with the elastic force of the second spring 25 to make the fourth half wheel 24 slide on the bidirectional screw 31, and the position of the speed regulating belt 23 between the third half wheel 26 and the fourth half wheel 24 can be adjusted. Cooperating with the elastic force of the first spring 22, the second half wheel 21 will also be driven to slide on the movable rod 17. The position of the speed regulating belt 23 between the third half wheel 26 and the fourth half wheel 24 is also adjusted. The speed regulating belt 23 can be adjusted by adjusting the transmission ratio between the first half wheel 32 and the second half wheel 21 and the third half wheel 26 and the fourth half wheel 24 through the different transmission ratios between the first half wheel 32 and the second half wheel 21 and the third half wheel 26 and the fourth half wheel 24. The rotation speed of the bidirectional screw 31 and the cam 33 can be adjusted. The lower the inclined strip 11 drops, the greater the range of movement of the adjusting strip 20 and the fourth half wheel 24. The smaller the transmission ratio between the speed regulating belt 23 and the third half wheel 26 and the fourth half wheel 24 is, the faster the rotation speed of the bidirectional screw 31 and the cam 33 is, and the piston frame 36 can be improved. The speed of pushing oxygen in the oxygen cylinder 3 increases the speed of pushing the defoaming agent in the discharge barrel 2 by the feeding plate 34, so that the more sludge in the sludge box 1, the faster the oxygen delivery speed and the faster the defoaming agent delivery speed are. The delivery speeds of oxygen and defoaming agent can be controlled according to the amount of sludge to be processed, which can avoid the increase in energy consumption when the amount of organic sludge processed is too small and the oxygen supply speed is too fast, so as to ensure the cost of organic sludge processing, prevent the microorganisms in the sludge from not obtaining enough oxygen to carry out normal physiological activities, avoid the generation of foam in the sludge as much as possible, and reduce the difficulty of subsequent sludge processing; (7) Oxygen heads 8, discharge heads 9 and detection blocks 38 are arranged at different height positions in the sludge tank 1. According to the different dissolved oxygen concentrations at different height positions of the sludge in the sludge tank 1, the oxygen output volume of multiple oxygen heads 8 and the defoamer discharge volume of multiple discharge heads 9 can be respectively controlled, so as to avoid as much as possible the different dissolved oxygen concentrations of the sludge at different height positions in the sludge tank 1, ensure the aerobic treatment effect of the sludge in the sludge tank 1, carry out aeration and defoaming treatment on the sludge at different height positions with oxygen and defoamer, improve the dissolved oxygen concentration of the sludge, avoid as much as possible the different aeration and defoaming effects at different height positions of the sludge, prevent the unstable aerobic treatment effect of the sludge and the poor defoaming effect, and ensure the sludge treatment speed; (8) When the detection block 38 stirs the sludge, the angle of the detection block 38 on the swing rod 37 can be adjusted in cooperation with the tension spring, and the sludge viscosity can be detected. When the sludge viscosity is relatively high, the resistance to the detection block 38 is greater, and the swing angle of the detection block 38 on the swing rod 37 is greater. The dissolved oxygen concentration in the sludge can be detected according to the sludge viscosity. When multiple detection blocks 38 rotate, they can respectively push the corresponding multiple wedge blocks 43 to move, and can respectively drive multiple air outlet plates 42, multiple connecting rods 44 and multiple discharge plates 45 to move. In cooperation with multiple compression springs 41 and multiple connecting springs 46, multiple oxygen heads 8 and multiple discharge heads 9 can be frequently opened and closed, and multiple oxygen heads 8 and multiple discharge heads 9 can synchronously put oxygen and defoamer into the sludge tank 1 to carry out aerobic and defoaming treatment on the sludge; (9) Due to the different viscosities at different height positions of the sludge, the resistance borne by the tension spring when multiple detection blocks 38 rotate is also different, and the swing angle of each detection block 38 on each swing rod 37 is also different. Furthermore, the larger the included angle of the detection block 38 on the swing rod 37, the more contact positions between the detection block 38 and the wedge block 43 during rotation. Furthermore, the opening gap in the oxygen head 8 and the discharge head 9 is larger, and furthermore, the output volume of oxygen and defoamer is larger. The output volume of oxygen and defoamer can be controlled according to the different dissolved oxygen concentrations of the sludge. The greater the viscosity of the sludge, the lower the dissolved oxygen concentration, and furthermore, the more oxygen and defoamer are added. The addition amount of oxygen and defoamer can be accurately controlled according to the dissolved oxygen concentration of the sludge at different heights, and the treatment effect of oxygen and defoamer on the sludge can be ensured; When the lifting plate 10 gradually moves downward due to the weight of the sludge, it will come into contact with the induction switch 49 on the double-sided wedge block 40, which can open the first one-way solenoid valve 48 and the second one-way solenoid valve 47 on the oxygen head 8 and the discharge head 9 at the corresponding height, so that the oxygen head 8 and the discharge head 9 at the corresponding height are opened to feed oxygen and defoamer. When the lifting plate 10 moves upward driven by multiple measuring springs 12 due to the reduction of the sludge, the induction switch 49 comes into contact, which can close the first one-way solenoid valve 48 and the second one-way solenoid valve 47 on the oxygen head 8 and the discharge head 9 at the corresponding height, so that the oxygen head 8 and the discharge head 9 at the corresponding height are closed to stop feeding oxygen and defoamer. By this method, the specified number of oxygen heads 8 and discharge heads 9 can be opened according to the amount of sludge treatment, avoiding waste of oxygen and defoamer caused by excessive opening of the oxygen heads 8 and discharge heads 9, so as to ensure that the sludge is treated with the optimal amount of oxygen and defoamer, and avoid excessive or insufficient input of oxygen and defoamer, which can not only ensure the sludge treatment effect but also avoid waste of oxygen and defoamer. When the sludge on the lifting plate 10 is discharged, the weight on the lifting plate 10 will change, and the multiple measuring springs 12 can drive the lifting plate 10 to move upward by their elastic force, so that the lifting plate 10 can automatically return to its original state after the sludge treatment is completed.

[0043] The embodiment of the present application also discloses a treatment method for organic sludge. Based on the treatment device for organic sludge in Embodiment 1, it includes the following steps: S1. Pour the sludge into the sludge tank 1. The downward movement of the lifting plate 10 driven by the weight of the sludge can detect the amount of sludge treatment. According to the amount of sludge, the specified number of oxygen heads 8 and discharge heads 9 can be opened to spray oxygen and defoamer, which can be evenly sprayed on different positions of the sludge to perform aerobic and defoaming treatment on the sludge at different height positions. S2. When the motor 6 drives multiple swing rods 37 and multiple detection blocks 38 to rotate, the sludge can be stirred, so that the oxygen and defoamer are evenly mixed with the sludge. When the lifting plate 10 moves up and down, the speed of the piston frame 36 moving up and down can be controlled. The more sludge there is, the faster the oxygen and defoamer are transported. S3. When the multiple detection blocks 38 rotate, the dissolved oxygen concentration at different height positions of the sludge can be detected. When the multiple detection blocks 38 rotate, the moving ranges of the multiple air outlet plates 42 and the multiple discharge plates 45 can be respectively controlled according to the different viscosities of the sludge at different heights. The lower the dissolved oxygen concentration of the sludge, the more oxygen and defoamer are added.

[0044] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
