Description

Technical Field

[0001] The utility model belongs to the field of sludge and sewage treatment, and specifically relates to a sludge and sewage filtering and separation treatment device. Background Art

[0002] Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a water body or reuse. Since sewage is mixed with a large amount of sludge, it is necessary to filter and separate the sludge from the sewage during sewage purification.

[0003] The Chinese patent with the publication number CN219701355U discloses a sludge sewage filtering and separation treatment device, including a shell, a pre-precipitation mechanism is arranged inside the shell, and a filtering mechanism is also arranged inside the shell, and the pre-precipitation mechanism includes a sedimentation tank. The utility model relates to the technical field of sewage treatment. The sludge sewage filtering and separation treatment device is provided with a pre-precipitation mechanism, and the sewage is sent into the sedimentation tank through a pipeline, and the sludge is allowed to sink by standing. When the sludge is precipitated, the first motor is started to drive the closing plate to move downward, so that the precipitated sewage enters the filter tank along the guide plate and leaves the sludge in the sedimentation tank. When the sewage is filtered in the filter tank, the second motor is started, and the cleaning brush is driven by the second motor to scrub the surface of the filter screen plate, so that the sludge sewage can be smoothly filtered and separated, solving the problem of sludge blocking the filter equipment.

[0004] In the above-mentioned comparative document, a sludge sewage filtering and separation treatment device uses a second motor to drive a cleaning brush to scrub the surface of the filter screen. However, the cleaned sludge still accumulates on the filter screen, and the accumulated sludge still blocks the filter screen, affecting the filtration efficiency.

[0005] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model will now be further described in detail with reference to the accompanying drawings.

[0026] See also Figure 1-2As shown, in this embodiment, a sludge and sewage filtering and separation treatment device is provided, comprising a housing 1, a first cavity 8 and a second cavity 9 are provided in the housing 1, a cleaning component is installed on one side of the housing 1, two sludge filter plates 10 are installed in the first cavity 8, a sludge filter element is installed in the second cavity 9, and a pressing component is installed on the side of the housing 1, and the pressing component cooperates with the sludge filter element;

[0027] The cleaning assembly cooperates with two sludge filter plates 10, and two through grooves 12 are opened between the first cavity 8 and the second cavity 9. A rotating rod 13 is rotatably matched in the two through grooves 12, and a blocking plate 14 is installed on the rotating rod 13. A torsion spring is installed at the rotation point of the rotating rod 13 and the through groove 12; filter holes 11 are provided on the two sludge filter plates 10, and the two sludge filter plates 10 are divided into a first plate and a second plate, and the aperture of the filter hole 11 of the first plate is larger than the aperture of the filter hole 11 of the second plate.

[0028] One aspect of the application of this embodiment is as follows: when in use, the sewage to be treated is sent into the first cavity 8 to be allowed to settle, the sewage and the sludge are initially separated, and the sludge is accumulated on the sludge filter plate 10 near the top of the first cavity 8. The separated sewage will flow to the sludge filter plate 10 near the bottom of the first cavity 8 under the action of gravity for secondary filtration, and the cleaning component is powered on and started, and the cleaning component reciprocates to scrub the two sludge filter plates 10. When the sludge on the sludge filter plate 10 is pushed, the sludge squeezes the blocking plate 14, causing the rotating rod 13 to rotate, so that the sludge on the sludge filter plate 10 passes through the through groove 12 and enters the second cavity 9. , and falls on the sludge filter element under the action of gravity, avoiding the sludge from accumulating on the sludge filter plate 10, preventing the small amount of sludge mixed in the sewage from clogging the sludge filter plate 10 and affecting the filtering efficiency. When the cleaning component is no longer pushing the sludge, under the action of the torsion spring, the blocking plate 14 is reset to avoid affecting the sludge filter plate 10 in separating sewage and sludge. At the same time, the pressing component is started, and the pressing component squeezes the sludge on the sludge filter element, so that the sewage remaining in the sludge on the sludge filter element is squeezed out through the sludge filter element and stored at the bottom of the second cavity 9, thereby completing the filtering and separation of sludge and sewage, and effectively improving the filtering effect.

[0029] See also Figure 1-2 As shown, the cleaning assembly of this embodiment includes an electric telescopic rod 5 installed on one side of the shell 1, and two cleaning brushes 7 that are slidably fitted on two filter plates respectively. A U-shaped driving rod 6 is installed at the output end of the electric telescopic rod 5, and the two ends of the U-shaped driving rod 6 are fixedly connected to the two cleaning brushes 7.

[0030] Through the cleaning assembly, the electric telescopic rod 5 is energized and started, and the electric telescopic rod 5 drives the reciprocating motion of the U-shaped driving rod 6, so that the U-shaped driving rod 6 drives the two cleaning brushes 7 to reciprocate. When the U-shaped driving rod 6 pushes the two cleaning brushes 7, the two cleaning brushes 7 push the sludge on the two sludge filter plates 10 respectively, and the sludge squeezes the blocking plate 14 to rotate the rotating rod 13, so that the sludge in the first cavity 8 enters the second cavity 9 through the through groove 12 and falls on the sludge filter element under the action of gravity. When the U-shaped driving rod 6 pulls the two cleaning brushes 7, the blocking plate 14 is reset under the action of the torsion spring.

[0031] See also Figure 1-2 As shown, the bottom of the inner wall of the two through grooves 12 of this embodiment is located at the same horizontal plane as the upper surface of the two sludge filter plates 10 , so that the sludge on the sludge filter plates 10 can enter the second cavity 9 through the through grooves 12 .

[0032] See also Figure 1-2 As shown, a mud discharge pipe 4 is installed on one side of the shell 1 of this embodiment, and the sludge filter element includes two arc-shaped filter plates 15 respectively installed on both sides of the inner wall of the second cavity 9, and a discharge filter plate 16 is installed between the two arc-shaped filter plates 15. The mud discharge pipe 4 is connected to the discharge filter plate 16; the discharge filter plate 16 is provided with an inclined surface, and a sealing plug is provided on the mud discharge pipe 4.

[0033] When the sludge falls on the sludge filter, the two arc filter plates 15 make the sludge slide into the discharge filter plate 16. Due to the inclined surface provided on the discharge filter plate 16, the sludge can be discharged from the sludge discharge pipe 4 more conveniently.

[0034] See also Figure 1-3 As shown, the pressing assembly of this embodiment includes a U-shaped mounting frame 17 installed on the side of the shell 1, a cylinder 18 is installed at the bottom of the U-shaped mounting frame 17, an extrusion piece 19 is installed at the output end of the cylinder 18, and the top of the extrusion piece 19 is located on both sides of the cylinder 18 and a limiting rod 20 is installed, and a limiting hole is opened at the top of the U-shaped mounting frame 17, and the limiting rod 20 slides in the limiting hole.

[0035] By means of the downward pressing assembly, the cylinder 18 is started, and the cylinder 18 drives the extruding member 19 to move toward the sludge filter element under the restriction of the limit rod 20 and squeeze the sludge on the sludge filter element. Under the squeezing of the extruding member 19, the sewage remaining in the sludge is squeezed out through the filter holes on the two arc-shaped filter plates 15 and the discharge filter plate 16, and is stored at the bottom of the second cavity 9, thereby completing the filtering and separation treatment of the sludge and sewage.

[0036] See also Figure 1-2As shown, a first water outlet pipe 2 is installed on the side of the shell 1 of this embodiment, and the first water outlet pipe 2 is connected to the first cavity 8.
