Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tanks, in particular to a water distribution device for a Lamela sedimentation tank. Background Art

[0002] A Lamela sedimentation tank typically consists of a shell with a water inlet at the front and a water outlet at the rear. The shell is divided into a water inlet area, a sludge collection area, a sedimentation area, and a water outlet area, which are connected in sequence. Sewage containing suspended solid waste such as sediment or flocs enters the water inlet area through the water inlet, then enters the sedimentation area through the sludge collection area, where it settles. However, as the length of the sedimentation tank increases and the number of sludge collection areas increases, suspended solid waste is usually concentrated in the sludge collection area near the water inlet, while less sediment is deposited in the sludge collection area far from the water inlet. Excessive concentration of suspended solid waste can easily lead to a decrease in sedimentation efficiency.

[0003] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0027] First embodiment:

[0028] This embodiment discloses a water distribution device for a Lamela sedimentation tank.

[0029] like Figures 1 to 3 As shown, the water distribution device of the Lamela sedimentation tank includes a shell 1, a water inlet 2, a water outlet 4 and a guide plate 3.

[0030] The shell 1 is a hollow structure with an upward opening, including two partitions 11, which are arranged parallel to each other, with the front and rear ends connected to the inner wall of the shell 1, and the lower end not in contact with the bottom of the shell 1. The two partitions 11 divide the interior of the shell 1 into a water inlet area 12, a mud collection area 13, a sedimentation area 14, and a water outlet area 15, which are connected in sequence. The water inlet area 12 is located between the two partitions 11, the mud collection area 13 is located at the lower end of the partition 11, the sedimentation area 14 and the water outlet area 15 are located on opposite sides of the two partitions 11, and the water outlet area 15 is located above the sedimentation area 14. Exemplarily, the shell 1 has an inclined frame 101 at the corresponding positions of the water inlet area 12, the sedimentation area 14, and the water outlet area 15. The water distribution device of the Lanmei sedimentation tank also includes an inclined plate assembly 5, which is fixed between the opposite side of the partition 11 and the shell 1, with the same inclination angle as the frame 101, to facilitate installation and sedimentation.

[0031] The water inlet 2 is connected to the side of the housing 1 and communicates with the water inlet area 12. The deflector 3 is connected to the inner wall of the housing 1 at its front and rear ends and to the partition 11 at its left and right ends, corresponding to the water inlet area 12. Several first through holes 31 are defined along its length. For example, the first through holes 31 can be square, round, or any other shape, as long as they allow sewage to pass through.

[0032] The water outlet 4 is connected to the side of the housing 1 and communicates with the water outlet area 15 .

[0033] Furthermore, the housing 1 has a rectangular pyramid 102 at the location corresponding to the mud collection area 13. This pyramid 102 is connected to the lower end of the frame 101. For example, there are two pyramids 102, arranged continuously along the length of the housing 1. These pyramids 102 facilitate the sedimentation of suspended solids along their four inclined surfaces to the bottom, facilitating their collection. Multiple pyramids 102 can increase the sedimentation tank's capacity for suspended solids and ensure effective sedimentation.

[0034] Furthermore, the water distribution device of the Lamela sedimentation tank also includes a mud discharge port 7, which is connected to the lower ends of both sides of the square pyramid 102 and communicates with the mud collection area 13 to discharge the precipitated solids.

[0035] Furthermore, the water distribution device of the Lanmela sedimentation tank also includes an outlet channel 6, the rear end of the outlet channel 6 is fixed to the rear end of the shell 1, and the position corresponds to the outlet area 15. Second through holes 61 are opened at the upper ends of both sides. The rear end of the outlet channel 6 is connected to the water outlet 4. The separated clean water overflows into the outlet channel 6 through the second through hole 61, further separating the suspended solids in the sewage.

[0036] Furthermore, support legs 16 are symmetrically provided on both sides of the shell 1 , and the lower ends of the support legs 16 are supported on the ground to support the sedimentation tank.

[0037] In this embodiment, after the sewage enters the water inlet area 12 through the water inlet 2, it flows downward into the mud collection area 13 through the first through hole 31 on the guide plate 3. The sewage flow rate and flow rate of the first through hole 31 at each location are nearly uniform, so as to achieve uniform water distribution when the sewage enters and ensure the sedimentation effect of suspended solids in the sewage.

[0038] Second embodiment:

[0039] Based on the first embodiment, the second embodiment further improves and refines the guide plate 3 of the first embodiment.

[0040] like Figures 4 to 6 As shown, the guide plates 3 have two pieces, and the two guide plates 3 are symmetrically connected, and the connection end of the two guide plates 3 is lower than the non-connection end, and the rear end of the two guide plates 3 is lower than the front end. Among them, the first through hole 31 is opened at the connection end of the two guide plates 3.

[0041] In this embodiment, when the sewage passes through the inclined guide plate 3, it moves faster toward the rear end of the guide plate 3 and toward the connecting end of the two guide plates 3, further improving the sewage water distribution effect, while improving the sewage flushing effect, avoiding suspended solids remaining on the guide plate 3 and affecting the water distribution, and improving the service life of the equipment.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
