[0032] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1 to 9 As shown, the sewage sedimentation tank for filtering with an inclined plate 3 provided by the utility model includes a box body 1, an inclined plate 3, an upper limit plate 4, a lower limit plate 5, a groove 8, a support plate 9, a height adjustment component, an inner connecting plate 10, an outer connecting plate 11 and a high-pressure injection pipe 12.

[0034] An inclined plate filter chamber 2 is provided inside the box body 1. The inclined plate filter chamber 2 is an isosceles trapezoidal structure, and the top length of the inclined plate filter chamber 2 is greater than the bottom length. The bottom end of the inclined plate filter chamber 2 is connected to a square transition chamber, and the bottom end of the transition chamber is connected to a mud discharge bucket.

[0035] Specifically, in this embodiment, two inclined plate filter chambers 2 are provided in the box body 1, and the two inclined plate filter chambers 2 are distributed on both sides of the inclined plate filter chamber 2 in the width direction, and the two inclined plate filter chambers 2 are spaced apart, and the interval between the two inclined plate filter chambers 2 is a sewage injection chamber, and a sewage injection pipe is connected to one side of the sewage injection chamber.

[0036] Inclined plates 3 are equidistantly arranged within the inclined plate filter chamber 2, parallel to one of the inclined surfaces of the inclined plate filter chamber 2. A baffle 13 is provided on one side of the inclined plate filter chamber 2. Both sides of the bottom end of the baffle 13 are rotatably mounted on the inner sidewall of the sedimentation tank of the inclined plate 3. A positioning component is provided between the inclined plate filter chamber 2 and the baffle 13, and is used to fix the baffle 13 in a state parallel to the inclined plate 3 or against one of the inclined surfaces of the inclined plate filter chamber 2.

[0037] Specifically, during operation of the inclined plate filtration sewage sedimentation tank, the baffle 13 is parallel to the inclined plate 3. At this time, the baffle 13 and the inclined plate 3 are both parallel to one of the inclined surfaces of the inclined plate filter chamber 2. Before cleaning the inclined plate 3, the baffle 13 is adjusted so that the baffle 13 is parallel to the other inclined surface of the inclined plate filter chamber 2.

[0038] Guide rods 6 are provided on both sides of the top and bottom ends of the inclined plate 3, and the bottom ends of the upper limit plate 4 and the lower limit plate 5 are provided with limit grooves 7 that are sleeved on the guide rod 6 from top to bottom. At this time, a limit groove 7 is provided on the upper limit rod and the lower limit rod corresponding to each inclined plate 3.

[0039] Specifically, during the operation of the sewage sedimentation tank with inclined plate filtration, the limit grooves 7 on the upper limit plate 4 and the lower limit plate 5 are both in a state of being sleeved on the guide rods 6 on the corresponding inclined plates 3 from top to bottom. In this way, the upper limit plate 4 and the lower limit plate 5 can limit the top and bottom ends of the inclined plates 3 respectively, so that the inclined plates 3 remain in a preset inclined state.

[0040] Furthermore, a groove 8 is defined on the inner sidewall of the inclined plate filter chamber 2, and the lower stop plate 5 is slidably mounted in the height direction within the groove 8. At this point, the lower stop plate 5 is entirely located within the groove 8, and the upper stop plate 4 is entirely located at the top of the inclined plate filter chamber 2. Both the upper stop plate 4 and the lower stop plate 5 are located outside the inclined plate 3 in the width direction of the inclined plate 3. Furthermore, the two end faces of the inclined plate 3 in the width direction maintain contact with the inner wall surfaces of the inclined plate filter chamber 2 on both sides.

[0041] The support plate 9 is supported on the bottom of the upper limit plate 4, and the support plate 9 blocks the bottom notch of the limiting groove 7 of the upper limit plate 4. A height adjustment component is provided between the upper limit plate 4 and the support plate 9 for adjusting the height of the upper limit plate 4 on the support plate 9. At this time, by operating the height adjustment component to move the upper limit plate 4 to the highest position on the support plate 9, the limiting groove 7 on the upper limit plate 4 can be disengaged from the guide rod 6 at the top end of the inclined plate 3. At this time, the limiting effect of the upper limit plate 4 on the top end of the inclined plate 3 can be released.

[0042] The inner connecting plates 10 are connected at both ends to the same side of the upper and lower limiting plates 4, 5, respectively. The inner connecting plates 10 are parallel to the inclined plates 3 and positioned within the inclined plate filter chamber 2. Specifically, four inner connecting plates 10 are positioned within the inclined plate filter chamber 2. For each upper and lower limiting plate 4 and 5 on the same side, they form a parallelogram with the inner connecting plates 10 at their ends. This ensures that the distance between the upper and lower limiting plates 4, 5 remains constant.

[0043] When the height adjustment component is operated to raise and lower the upper limit plate 4 on the support plate 9, the inner connecting plate 10 drives the lower limit plate 5 to rise and fall synchronously in the groove 8, so that when the guide rod 6 at the top end of the inclined plate 3 is disengaged from the limit groove 7 of the upper limit plate 4, the guide rod 6 at the bottom end of the inclined plate 3 is disengaged from the limit groove 7 of the lower limit plate 5. At this time, the inclined plate 3 can be moved in the longitudinal direction of the inclined plate filter chamber 2.

[0044] The bottom end of the outer connecting plate 11 is pivotally mounted on the outer sidewall of the inclined plate filter chamber 2, and its top end is pivotally connected to the support plate 9. The outer connecting plate 11 is the same length as the inner connecting plate 10 and is parallel to the inner connecting plate 10. Specifically, by rotating the outer connecting plate 11, it drives the support plate 9, which then rotates all the inclined plates 3 to a tilted position symmetrical to their operating state. This, in turn, causes the side of the inclined plate 3, which is facing downward in the operating state, to switch to an upward position, thereby achieving a cleaning effect on both sides of the inclined plate 3.

[0045] A high-pressure jet pipe 12 is installed above the inclined plate filter chamber 2, parallel to the width of the inclined plate filter chamber 2. It is used to spray high-pressure water downward to clean the inclined plate 3. The high-pressure jet pipe 12 is located in the middle of the coverage area at the top of the inclined plate 3 along the length of the inclined plate filter chamber 2. This arrangement ensures that after the inclined plate 3 rotates and switches its tilt direction, the position of the high-pressure jet pipe 12 relative to the inclined plate 3 along the length of the inclined plate filter chamber 2 remains unchanged.

[0046] With the above arrangement, during the flushing process of the inclined plate 3, after the high-pressure jet pipe 12 is connected to the pump body, the pump body injects water into the high-pressure jet pipe 12. The upper and lower limit plates 4 and 5 are displaced upward by the height adjustment component, allowing the guide rods 6 at the upper and lower ends of the inclined plate 3 to disengage from the limit slots 7. The inclined plates 3 can then be translated so that all inclined plates 3 are closely aligned and concentrated at one end of the inclined plate filter chamber 2. Each inclined plate 3 is then passed back and forth through the high-pressure jet pipe 12, thoroughly flushing the upward-facing surface of the inclined plate 3. The external connecting plate 11 is then rotated to switch the inclined surface of the inclined plate 3 from facing downward to facing upward. The above operation is then repeated, with each inclined plate 3 passing through the high-pressure jet pipe 12, achieving a full flushing of the originally downward-facing surface of the inclined plate 3. In summary, this allows for full flushing of both surfaces of the inclined plate 3, significantly improving the cleaning efficiency of the inclined plate 3. Compared to the existing method of flushing by manually holding a high-pressure water gun, this method provides better flushing results and is more convenient to operate.

[0047] Among them, when the baffle 13 is parallel to the inclined plate 3, its lower surface is attached to the inner wall surface of the inclined surface of the inclined plate filter chamber 2, and the bottom end of the outer side of the baffle 13 is fixedly installed with a mounting shaft 14. The two ends of the mounting shaft 14 are respectively inserted into the inner walls on both sides of the inclined plate filter chamber 2, and the inner wall surface of the inclined surface of the inclined plate filter chamber 2 is provided with a receiving groove 15 for accommodating the mounting shaft 14.

[0048] The positioning components include positioning bolts 21 threadedly mounted on both sides of the top of the baffle 13 and positioning holes 22 opened on the inner walls of both sides of the inclined plate filter chamber 2.

[0049] Furthermore, both ends of the bottom notch of the limiting groove 7 are configured to be outwardly expanded, and the inner width of the limiting groove 7 is adapted to the outer diameter of the guide rod 6. The guide rod 6 is mounted on the end of the inclined plate 3 via a support plate. This configuration allows the upper and lower limiting plates 4 and 5 to descend after the inclined plate 3 is cleaned and moved to its initial position, allowing the limiting groove 7 to be re-engaged with the guide rod 6. The outward expansion of the bottom notch of the limiting groove 7 makes it easier for the limiting groove 7 to be reengaged with the guide rod 6, while also allowing for a certain degree of operating tolerance.

[0050] Among them, the support plate 9 is an "L"-shaped plate, the upper limit plate 4 is slidably installed on the support plate 9 in the height direction, and when the upper limit plate 4 is at the highest position on the support plate 9, the distance between its bottom end and the inner top wall of the support plate 9 is greater than or equal to the outer diameter of the guide rod 6.

[0051] The height adjustment component includes a bolt 16 and a threaded groove 17. The threaded groove 17 is provided on the upper limit plate 4. The bolt 16 is threadedly inserted into the threaded groove 17. The bottom end of the bolt 16 is rotatably connected to the support plate 9. At this time, the height of the upper limit plate 4 on the support plate 9 can be adjusted by rotating the bolt 16, so that the limit groove 7 can be disengaged from the guide rod 6 or the limit groove 7 can be downwardly inserted into the guide rod 6.

[0052] The outer portion of the outer connecting plate 11 is provided with a plate sleeve 18, on the surface of which a threaded sleeve 19 is rotatably mounted. A screw 20 is internally threadedly connected to the threaded sleeve 19, and the screw 20 is rotatably mounted on the top of the inclined plate filter chamber 2. Specifically, by rotating the screw 20, the plate sleeve 18 is driven, via the threaded sleeve 19, to move back and forth along the length of the inclined plate filter chamber 2. During this process, the plate sleeve 18 slides on the surface of the outer connecting plate 11, simultaneously driving the outer connecting plate 11 to swing about its bottom end, thereby switching the two surfaces of the inclined plate 3 to an upward position.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
