Description

Technical Field

[0001] The utility model relates to the technical field of garbage leachate treatment equipment, and more specifically, to a photocatalytic treatment device for garbage leachate. Background Art

[0002] Leachate refers to the filtrate containing organic and inorganic components produced during the stacking and landfilling of garbage due to a series of complex physical, chemical and biological effects such as compaction and fermentation, as well as the moisture in the garbage itself and the seepage of water such as precipitation. Leachate is extremely harmful to the environment. Therefore, how to deal with leachate is one of the thorny problems faced by all garbage disposal sites today.

[0003] When operators carry out photocatalytic treatment of landfill leachate, they often use a photocatalytic treatment device to decompose organic matter in the landfill leachate through catalysts and certain light conditions, thereby ensuring that the treated landfill leachate does not pollute the natural environment. In actual use, although the existing photocatalytic treatment devices have basic catalytic treatment functions, the volume of the cylinder containing the landfill leachate in the existing photocatalytic treatment devices is generally not changeable, and the volume inside the cylinder cannot be adjusted according to the amount of landfill leachate, so it needs to be improved.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 5 As shown, the utility model provides a photocatalytic treatment device for landfill leachate, comprising:

[0028] A bottom plate 1, a support column 2 is fixedly connected to the upper surface of the bottom plate 1, and a fixing cylinder 3 is fixedly connected to the upper surface of the support column 2;

[0029] A movable cylinder 4, the inner surface of which is movably sleeved on the upper surface of the fixed cylinder 3, a top plate 5 is fixedly connected to the upper surface of the movable cylinder 4, and a tooth plate 6 located outside the movable cylinder 4 is fixedly connected to the right side of the lower surface of the top plate 5;

[0030] An adjustment mechanism, the adjustment mechanism is arranged on the right side of the moving cylinder 4;

[0031] Among them, the adjustment mechanism includes a No. 1 motor 7, which is fixedly installed at the lower left side of the outer surface of the fixed cylinder 3. The other end of the output shaft of the No. 1 motor 7 is fixedly sleeved with a round shaft 8, and the outer surface of the round shaft 8 is fixedly sleeved with a gear 9 located on the right side of the gear plate 6. The outer surface of the gear 9 is meshed with the outer surface of the gear plate 6. The rotation of the gear 9 causes the gear plate 6 to drive the top plate 5 and the movable cylinder 4 to move upward as a whole.

[0032] When motor No. 1 7 is running, the circular shaft 8 will start to rotate and drive the gear 9 to start rotating. Due to the meshing between the toothed plate 6 and the outer surface of the gear 9, the rotation of the gear 9 will cause the toothed plate 6 to drive the top plate 5 and the moving cylinder 4 as a whole to start moving upward under the limit of the outer surface of the fixed cylinder 3.

[0033] Among them, the lower side of the outer surface of the fixed cylinder 3 is fixedly connected with a limit ring 10 located below the moving cylinder 4, and the top of the outer surface of the moving cylinder 4 is fixedly installed with a valve No. 11, and the other end of the valve No. 1 passes through the moving cylinder 4 and extends to the interior of the moving cylinder 4.

[0034] Due to the design of valve No. 1 1 , the operator can control the inflow of landfill leachate into the fixed cylinder 3 .

[0035] Among them, the inner surfaces of the fixed cylinder 3 and the movable cylinder 4 are both fixedly installed with a waterproof ultraviolet lamp 12, and a No. 2 valve 13 is fixedly installed in the middle of the bottom end of the inner surface of the fixed cylinder 3, and the other end of the No. 2 valve 13 penetrates the fixed cylinder 3 and extends to the bottom of the fixed cylinder 3.

[0036] The design of the waterproof ultraviolet lamp 12 allows the garbage leachate inside the fixed cylinder 3 and the movable cylinder 4 to react with the catalyst under the irradiation of light.

[0037] Among them, a No. 2 motor 14 is fixedly installed on the bottom end of the outer surface of the fixed cylinder 3, and a driving shaft 15 is fixedly sleeved on the other end of the output shaft of the No. 2 motor 14. The bottom end of the driving shaft 15 passes through the top plate 5 and extends to the interior of the fixed cylinder 3. The lower side of the outer surface of the driving shaft 15 is movably sleeved with a reactor 16.

[0038] The outer surface of the reactor 16 is covered with a catalyst film that can react with the landfill leachate. These catalyst films can react with the landfill leachate under the irradiation of the waterproof ultraviolet lamp 12.

[0039] Among them, the front and rear ends of the left side of the upper surface of the base plate 1 are fixedly connected with a fixing plate 17, the front surface of the fixing plate 17 is fixedly installed with a No. 3 motor 18, the other end of the output shaft of the No. 3 motor 18 is fixedly sleeved with a double-threaded lead screw 19, and the other end of the double-threaded lead screw 19 passes through the fixing plate 17 and extends to the rear surface of the fixing plate 17.

[0040] When the third motor 18 is running, the double-threaded lead screw 19 will rotate.

[0041] Among them, the front and rear sides of the outer surface of the double-threaded screw 19 are both threadedly connected with movable plates 20, and the number of movable plates 20 is two. The inner surfaces of the right sides of the two movable plates 20 are movably connected with a No. 1 limit rod 21, and the front and rear ends of the No. 1 limit rod 21 are fixedly connected to the inner surface of the fixed plate 17.

[0042] The design of the No. 1 limiting rod 21 limits the moving direction of the moving plate 20 , thereby ensuring the stability of the moving directions of the two moving plates 20 .

[0043] Among them, the top of the right surface of the two movable plates 20 is hinged with a No. 1 connecting rod 22, the other end of the No. 1 connecting rod 22 is hinged with a No. 2 connecting rod 23, the other end of the No. 2 connecting rod 23 is hinged with a connecting frame 24, and the front and rear ends of the right side of the upper surface of the connecting frame 24 are fixedly connected with a push plate 25 located under the reactor 16, and the top end of the push plate 25 penetrates the fixed cylinder 3 and extends to the lower surface of the reactor 16 and is movably connected to the lower surface of the reactor 16.

[0044] When the double-threaded screw 19 rotates and causes the two movable plates 20 to start moving toward each other, the two No. 1 connecting rods 22 will respectively rotate with the top of the right surface of the two movable plates 20 as the axis. During this process, the two No. 2 connecting rods 23 will also respectively rotate with the other end of the two No. 1 connecting rods 22 as the axis. At this time, the other end of the two No. 2 connecting rods 23 will push the connecting frame 24 to start moving upward as a whole, which causes the pushing plate 25 to push the reactor 16 to start moving upward along the outer surface of the driving shaft 15.

[0045] Among them, the front and rear sides of the upper surface of the base plate 1 are fixedly connected with a No. 2 limit rod 26 located on the left side of the push plate 25. The top end of the No. 2 limit rod 26 passes through the connecting frame 24 and extends to the lower surface of the fixed tube 3. The outer surface of the No. 2 limit rod 26 and the inner surface of the connecting frame 24 are movably connected.

[0046] The design of the second limiting rod 26 limits the movement of the connecting frame 24 .

[0047] The working principle and use process of this utility model:

[0048] The operator introduces the garbage leachate into the interior of the fixed cylinder 3 and the movable cylinder 4 through the No. 1 valve 11, and then starts the waterproof ultraviolet lamp 12 and the No. 2 motor 14. The activation of the waterproof ultraviolet lamp 12 causes the light to begin to irradiate the garbage leachate in contact with the catalyst film on the outer surface of the reactor 16, so that the organic matter in this part of the leachate begins to decompose, and the operation of the No. 2 motor 14 causes the driving shaft 15 to drive the reactor 16 to start rotating, so that the reactor 16 fully contacts all the leachate inside the fixed cylinder 3 as a whole, thereby accelerating the effect of the photocatalytic treatment of the garbage leachate.

[0049] When a large amount of leachate is generated after garbage treatment, the operator starts motor No. 1 7. The operation of motor No. 1 7 causes the circular shaft 8 to drive the gear 9 to start rotating. Due to the meshing between the tooth plate 6 and the outer surface of the gear 9, the rotation of the gear 9 drives the tooth plate 6, so that the tooth plate 6 starts to drive the top plate 5 and the moving cylinder 4 to move upward as a whole under the limitation of the fixed cylinder 3. During this process, the total volume inside the fixed cylinder 3 and the moving cylinder 4 gradually increases, so that the fixed cylinder 3 as a whole can accommodate more leachate.

[0050] When the internal volume of the fixed cylinder 3 meets the requirement, the operator turns off the No. 1 motor 7 and starts the No. 3 motor 18. The operation of the No. 3 motor 18 will cause the double-threaded screw 19 to start rotating, which makes the two movable plates 20 start to move towards each other under the limit of the No. 1 limit rod 21, and the movement of the two movable plates 20 will cause the two No. 1 connecting rods 22 to start rotating with the top of the right surface of the two movable plates 20 as the axis, and the two No. 2 connecting rods 23 will start to rotate with the other side of the two No. 1 connecting rods 22 respectively under the drive of the two No. 1 connecting rods 22. One end rotates about the axis, and at the same time, the other end of the two No. 2 connecting rods 23 will drive the connecting frame 24 as a whole, so that the connecting frame 24 and the push plate 25 begin to move up and down under the limit of the No. 2 limit rod 26. At the same time, the movement of the push plate 25 will drive the reactor 16, so that the reactor 16 begins to move up and down along the outer surface of the driving shaft 15. In this process, the reactor 16 is in full contact with the garbage leachate inside the fixed cylinder 3 as a whole, ensuring that the garbage leachate inside the fixed cylinder 3 can be fully treated.
