Description

Technical Field

[0001] The invention relates to the field of biological treatment of garbage wastewater, and more specifically, to a biological treatment device for garbage leachate. Background Art

[0002] In the treatment of garbage leachate, common methods include chemical treatment and biological treatment. The more commonly used method is biological treatment, which uses the organic matter required for the reproduction of microorganisms to purify the organic matter in the garbage leachate, so as to achieve the purpose of reducing the organic matter in the wastewater.

[0003] In the biological treatment process, there is a distinction between aerobic microorganisms and anaerobic microorganisms. For the reproduction of aerobic microorganisms, dissolved oxygen in sewage is essential. As the microorganisms themselves continue to reproduce, if oxygen is not added to the water, the purification ability of the microorganisms will gradually fade until the microorganisms die.

[0004] The Chinese patent with patent number 202022273872.9 does not disclose an aeration device similar to the above, which is not conducive to the survival of aerobic microorganisms. Summary of the invention

[0005] In order to overcome the above defects of the prior art, the present invention provides a biological treatment device for landfill leachate. The technical problem to be solved by the present invention is that for the reproduction of aerobic microorganisms, the treatment system does not have effective aeration equipment and the aeration equipment is not easy to clean.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a biological treatment device for leachate, comprising fan blades, a second motor, a rotor, a slide rod, a driving mechanism and a cleaning mechanism, wherein the output end of the second motor and the rotor are fixedly arranged, the rotor and the slide rod are fixedly arranged, a fan blade is slidably arranged on the outer side of the slide rod, the fan blade is elastic, a driving mechanism for driving the fan blade to slide along the slide rod is arranged on one side of the fan blade, and a cleaning mechanism is arranged on the outer side of the fan blade.

[0007] Preferably, a guide groove is provided on the rotor.

[0008] Preferably, the fan blades are slidably arranged via a sliding block and a sliding rod, and the sliding block and the sliding rod are detachably arranged.

[0009] Preferably, the sliding block is made of magnets, and the magnetic poles of two adjacent sliding blocks repel each other.

[0010] Preferably, the driving mechanism includes a first motor, the output end of the first motor and the screw rod are fixedly arranged, the screw rod and the threaded block are threadedly arranged, the threaded block and the inner wall of the sleeve are slidingly arranged in contact, a top block is slidingly arranged on the threaded block, and the fan blades are located on the moving stroke of the top block.

[0011] Preferably, a limiting groove is provided on the threaded block, and the top block slides in the limiting groove.

[0012] Preferably, the cleaning mechanism includes a fourth connecting rod, the fourth connecting rod and the third connecting rod are symmetrically arranged, and cleaning claws are fixedly arranged on the fourth connecting rod and the third connecting rod, the fourth connecting rod and the third connecting rod are arranged between them through the second connecting rod, one end of the fourth connecting rod is rotatably arranged on the bottom plate, one end of the third connecting rod and the first connecting rod are rotatably arranged, the first connecting rod and the bottom plate are rotatably arranged, the bottom plate and the cover body are fixedly arranged, and the bottom plate and the cover body remain stationary relative to the tank body of the sewage treatment tank.

[0013] Preferably, the cleaning claw is movably arranged inside by means of a plurality of ball bearings and a plurality of guide plates, and the plurality of ball bearings and the plurality of guide plates are arranged in a one-to-one correspondence.

[0014] Technical effects and advantages of the present invention:

[0015] 1. When the rotor rotates at a high speed in the cover, a space with a smaller water flow pressure will be formed on the circumference of the rotor. The water flow on the circumference of the space will continue to approach the space under the action of the fluid pressure. Moreover, the fan blades will push the water flow while rotating, so that the water flow will be sent to the gap between the rotor and the cover, so that the water flow will be ejected from the upward gap between the rotor and the cover to achieve the purpose of aeration.

[0016] 2. The friction between the cleaning claws and the fan blades can remove the microbial clusters attached to the surface of the fan blades. Furthermore, when the cleaning claws and the fan blades are closed, a violent collision will occur between the spiral water flow and the cleaning claws. Through this collision, the water flow surface formed by the collision can splash out of the water surface, thereby improving the aeration capacity of the design, that is, maintaining normal aeration efficiency while also cleaning the fan blades.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1

[0026] See also Figure 1 , Figure 3 and Figure 4 For details, please refer to Figure 4 A biological treatment device for landfill leachate includes a fan blade 10 and a second motor 9 for driving the fan blade 10 to rotate, wherein the output end of the second motor 9 is fixedly connected to the rotor 2, the rotor 2 is fixedly connected to the slide bar 11, and the outer side of the slide bar 11 is slidably connected with the fan blade 10, and the fan blade 10 is elastic. When the second motor 9 is running, its output shaft will drive the rotor 2 to rotate in the cover body 1, and at the same time, through the fixed connection relationship between the slide bar 11 and the rotor 2, the fan blade 10 is driven to rotate. Because the fan blade 10 is spiral and elastic, when rotating, on the one hand, when the rotor 2 rotates at a high speed in the cover body 1, a space with a smaller water flow pressure will be formed on the peripheral side of the rotor 2, and the water flow on the peripheral side of the space will continue to approach the space under the action of the fluid pressure. Moreover, when the fan blade 10 rotates, it will play a role in pushing the water flow, so the water flow will be sent to the gap between the rotor 2 and the cover body 1, so that the water flow is sprayed from the upward gap between the rotor 2 and the cover body 1 to achieve the purpose of aeration. A driving mechanism for driving the fan blade 10 to slide along the slide rod 11 is disposed on one side of the fan blade 10 , and a cleaning mechanism is disposed on the outer side of the fan blade 10 .

[0027] like Figure 4 The rotor 2 is provided with a guide groove, which is convenient for guiding the water flow to spray in a specified direction to achieve the purpose of fixed-point aeration.

[0028] like Figure 4The fan blade 10 is slidably connected via a sliding block and a sliding rod 11, and the sliding block and the sliding rod 11 are detachably connected. The sliding block can only move along the axis of the sliding rod 11, and cannot rotate relative to the sliding rod 11, so that the sliding block can rotate with the rotor 2.

[0029] like Figure 4 The sliding blocks are made of magnets, and the magnetism of two adjacent sliding blocks is the same. In the absence of external push, because the magnetic poles on the adjacent sliding blocks are of the same polarity, there is a magnetic repulsion between the two adjacent sliders, so that when rotating, the fan blades 10 will not be deformed in a clustered manner.

[0030] Embodiment 2

[0031] Please participate Figure 1 , Figure 3 and Figure 4 Based on the above embodiments, please refer to Figure 4 The driving mechanism includes a sleeve 4, a screw rod 13 and a first motor 5. The output end of the first motor 5 is fixedly connected to the screw rod 13. The screw rod 13 is threadedly connected to the threaded block 14. The threaded block 14 is slidably connected to the inner wall of the sleeve 4. The threaded block 14 is slidably connected to the top block 12. The fan blade 10 is located on the moving stroke of the top block 12. The first motor 5 is running, driving the screw rod 13 to control the threaded block 14 to slide on the screw rod 13. The threaded block 14 and the sleeve 4 slide relative to each other. At this time, the threaded block 14 can continuously approach the fan blade 10, so that the threaded block 14 drives the top block 12 to squeeze the fan blade 10 to deform, so that the fan blade 10 gradually undergoes aggregate deformation, which is convenient for the subsequent cleaning of the microbial clusters attached to the outer side of the fan blade 10.

[0032] like Figure 4 The thread block 14 is provided with a limiting groove, and the top block 12 slides in the limiting groove. In this way, when the screw rod 13 reversely drives the thread block 14 to be recovered, the top block 12 will not interfere with the sleeve 4, thereby preventing the entire device from being unable to be used normally.

[0033] Embodiment 3

[0034] See also Figure 1 , Figure 2 and Figure 5 Based on the above embodiments, please refer to Figure 2The cleaning mechanism includes a fourth connecting rod 18, a second connecting rod 6, a base plate 7 and a cleaning claw 8. The fourth connecting rod 18 and the third connecting rod 17 are symmetrically arranged, and the fourth connecting rod 18 and the third connecting rod 17 are fixedly connected with the cleaning claw 8. The fourth connecting rod 18 and the third connecting rod 17 are connected through the second connecting rod 6. One end of the fourth connecting rod 18 is rotatably connected to the base plate 7, one end of the third connecting rod 17 is rotatably connected to the first connecting rod 3, the first connecting rod 3 is rotatably connected to the base plate 7, and the base plate 7 and the cover body 1 remain relatively stationary. When the fan blades 10 undergo aggregate deformation, the user presses the first connecting rod 3 so that the first connecting rod 3 can rotate with the base plate 7, and driven by the second connecting rod 6, the fourth connecting rod 18 and the third connecting rod 17 are driven to control the corresponding cleaning claws 8 to squeeze the fan blades 10. Under the friction contact between the cleaning claws 8 and the fan blades 10, the microbial clusters attached to the surface of the fan blades 10 are removed. Furthermore, when the cleaning claws 8 and the fan blades 10 are closed, the spiral water flow and the cleaning claws 8 will have a violent collision. Through this collision, the water flow surface formed by the collision can splash out of the water surface, thereby improving the aeration capacity of the present design. When the water flow splashed on the water surface gradually disappears, the first connecting rod 3 is reset, and the first motor 5 is driven in reverse, so that the entire device is restored to its original state, without causing delay defects in the normal aeration link, and the fan blades 10 can be cleaned while maintaining the normal aeration efficiency.

[0035] like Figure 5 The cleaning claw 8 is movably connected to a plurality of ball bearings 16 and a plurality of guide plates 15, and the plurality of ball bearings 16 and the plurality of guide plates 15 are arranged one by one. The guide plates 15 can be deflected in any direction under the support of the ball bearings 16, so as to further expand the radiation range of the water flow surface of the splashing water surface, thereby improving the aeration effect of the present design.
