Description

Technical Field

[0001] This invention relates to the field of leachate treatment technology, and in particular to a mechanism for clearing floating debris from leachate tanks. Background Technology

[0002] The leachate in waste-to-energy plants mainly comes from the moisture in the waste itself. Landfills also receive some rainwater, and food waste is mainly wastewater from catering businesses, which is usually treated together with the waste. Leachate is a complex, high-concentration organic wastewater. At the same time, leachate also contains a large amount of floating waste. If these floating objects are not treated in time, they will rise in the wastewater pool and cause the pool to overflow before it reaches its storage capacity, which not only affects the environment but also poses a safety hazard. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a floating debris clearing mechanism for leachate tanks that can promptly discharge floating debris and timely clear blockages.

Both the lower fixed rail and the upper fixed rail include a rail base and rail grooves distributed on the rail base along the length direction of the rail base.

[0005] The unblocking module includes several unblocking components distributed along the X-axis direction. The several unblocking components are inserted into the X-axis fixed rail group along the X-axis direction and can reciprocate along the X-axis direction.

The lower end face of the connecting shaft 330 fits against the upper end face of the third lubricating ring 121.

[0054] The working principle of this invention is as follows:

[0055] like Figures 1 to 11As shown, when the leachate level rises to the outlet of the leachate tank, the leachate and floating debris move towards the outlet together. Since the floating debris accumulates, in order to avoid affecting the discharge of leachate due to accumulation and causing the leachate in the leachate tank to overflow from the upper opening of the leachate tank, it is necessary to disperse the floating debris.

[0056] Specifically, such as Figure 1 , Figure 2 , Figures 8 to 10 As shown, when the drive motor 232 is started, the support block 233 moves along the axial direction of the guide rod 235. The connected first Y-axis moving rail 220 and second Y-axis moving rail 240 also move synchronously. The first Y-axis moving rail 220 is provided with six first left-side inclined guide rails 211a and six first right-side inclined guide rails 212a. The six first left-side inclined guide rails 211a form six included angles α1 with the X-axis of the first Y-axis moving rail 220. The values ​​of two adjacent included angles α1 are set to increase gradually from left to right. The six first right-side inclined guide rails 212a form six included angles β1 with the X-axis of the first Y-axis moving rail 220. The values ​​of two adjacent included angles β1 are set to increase gradually from right to left.

[0057] Similarly, six second left-side inclined guide rails 214a and six second right-side inclined guide rails 215a are provided on the second Y-axis moving rail 240. The six second left-side inclined guide rails 214a form six included angles α2 with the X-axis of the first Y-axis moving rail 220. The values ​​of two adjacent included angles α2 are set to increase gradually from left to right in an arithmetic progression. The six second right-side inclined guide rails 215a form six included angles β2 with the X-axis of the first Y-axis moving rail 220. The values ​​of two adjacent included angles β2 are set to increase gradually from right to left in an arithmetic progression. At the same time, a first Y-axis guide rail 213 coaxial with the axis of symmetry L1 is also provided on the first Y-axis moving rail 220, and a second Y-axis guide rail 216 located directly below the first Y-axis guide rail 213 is also provided on the second Y-axis moving rail 240.

[0058] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 10 and Figure 11 As shown, connecting shafts 330 are installed between the guide rails at corresponding positions on the first Y-axis moving rail 220 and the second Y-axis moving rail 240. When the Y-axis moving rail moves linearly along the Y-axis direction, the force generated on the connecting shaft 330 is... Y+ To or F Y- A directional force will produce F X+ To or F X-The force component in the X-axis propels the connecting shaft 330 to move linearly along the X-axis, and allows the two side walls of the second side wing 322 to engage in the wide groove 312a of the first side wing 312 of the adjacent unblocking block 310, forming a clamping action. At the same time, since the included angles of adjacent α1 and α2 and β1 and β2 are set at equal intervals, the obstruction caused by the difference in the moving distance of each connecting shaft 330 is avoided. Moreover, the guide rails at the corresponding positions are symmetrically arranged, ensuring the integrity and stability of the movement. As the drive motor 232 drives the two connected Y-axis moving rails to move linearly back and forth along the Y-axis, the first side wing 312 and the second side wing 322 set opposite to each other on the two adjacent connecting shafts 330 also move back and forth. The resulting reciprocating clamping action can conveniently disperse the floating objects and prevent the floating objects from accumulating.

[0059] Among them, such as Figures 1 to 4 As shown, during the movement of the Y-axis guide rail, since the first Y-axis guide rail 213 is equipped with a first lubricating ring 217, the lower end face of the cover plate 34 is in contact with the upper end face of the first lubricating ring 217. The second left inclined guide rail 214a, the second right inclined guide rail 215a, and the second Y-axis guide rail 216 are all equipped with second lubricating rings 218. The upper end wall of the annular groove on the connecting shaft 330 is in contact with the upper end face of the second lubricating ring 218, and the lower end wall of the annular groove... The lower end face of the connecting shaft 330 is in contact with the lower end face of the second lubricating ring 218; a third lubricating ring 121 is embedded in the rail groove 120 of the lower fixed rail 100a, and the lower end face of the connecting shaft 330 is in contact with the upper end face of the third lubricating ring 121; the upper slider 320b extends into the fourth lubricating ring 219, and the outer wall of the upper slider 320b is in contact with the inner wall of the fourth lubricating ring 219. This ensures the smoothness of the connecting shaft 330 in the X direction, while reducing wear and extending its service life.

[0060] It should be noted that the inner walls of the fourth lubrication ring 219 and the third lubrication ring 121 are both conical structures. Correspondingly, the outer walls of the upper slider 320b and the lower slider 320a are also adapted to be conical structures. Under the action of gravity, the conical surfaces fit more stably, and the connecting shaft 330 is less likely to move.
