Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage sedimentation and separation device. Background Art

[0002] Sewage refers to polluted water from daily life and production. It typically contains various harmful substances, such as organic matter, inorganic matter, and microorganisms, and has lost its original function. The main sources of sewage include domestic sewage, industrial wastewater, and agricultural wastewater.

[0003] Traditionally, sewage treatment methods use sedimentation methods, where sewage is discharged into a device and chemicals are added to accelerate the sedimentation of the media in the sewage, or the media in the sewage is allowed to settle naturally by standing still for a certain period of time.

[0004] However, when it is necessary to discharge the precipitated sewage in the device, it is impossible to separate the soil settled at the bottom and the precipitated sewage on the upper layer. When discharging the precipitated sewage, the soil at the bottom is easily discharged along with the flow of water, which is easy to affect the discharge of the precipitated sewage. Utility Model Content

[0005] The purpose of the utility model is to provide a sewage sedimentation and separation device in view of the defects and shortcomings of the existing technology.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a sewage sedimentation and separation device, comprising a sedimentation barrel, a water holding chamber for holding sewage provided on the sedimentation barrel, a mounting cover provided on the upper end of the sedimentation barrel, a water inlet pipe provided on the side end surface of the sedimentation barrel and connected to the water holding chamber for discharging sewage into the water holding chamber, a drain outlet provided on the front end surface of the sedimentation barrel, a drain plug provided on the front end surface of the sedimentation barrel and located in the drain outlet, a mud pressing plate which can be lifted and arranged on the sedimentation barrel and located in the water holding chamber, a plurality of pressure relief openings which penetrate the mud pressing plate, and a pressure relief opening provided between the mounting cover and the mud pressing plate for slowly driving the mud pressing plate to descend or rise in the water holding chamber.

[0007] A further improvement is that a screen is provided on the mud pressing disc in the pressure relief opening.

[0008] A further improvement is that a glass observation window is provided on the lower end surface of the sedimentation barrel.

[0009] A further improvement is that an annular scraper is provided on the peripheral side of the mud pressing plate for dropping the sludge remaining on the inner wall of the sedimentation barrel when the mud pressing plate rises or falls in the sedimentation barrel.

[0010] Further improvements are: the lifting device includes a rotating screw rotatably arranged between the mounting cover and the sedimentation barrel in the accommodating cavity, a reduction motor with a fixed end arranged on the mounting cover and an output end connected to the rotating screw, and a rotating motor arranged on the reduction motor for driving the reduction motor to rotate to drive the rotating screw to rotate, the rotating screw passes through the mud pressing plate, and the mud pressing plate is threadedly connected to the rotating screw, a guide rod is provided at the bottom of the mounting cover, and a guide hole is opened on the mud pressing plate for clearance fitting with the guide rod.

[0011] A further improvement is that: the rotating device includes a rotating circular hole passing through the middle end of the mounting cover, a rotating circular rod whose lower end is fixedly arranged at the middle end of the rotating disk and the upper end passes through the rotating circular hole, an arc-shaped waist hole passing through the mounting cover on one side of the rotating circular hole, a sliding connecting rod slidably arranged on the mounting cover in the arc-shaped waist hole, a moving block movably arranged on the upper end surface of the mounting cover and connected to the upper end of the sliding connecting rod for circumferential movement around the rotating circular rod when the sliding connecting rod slides in the arc-shaped waist hole, and a connecting piece arranged between the right end of the moving block and the rotating circular rod for driving the rotating circular rod to rotate together when the moving block moves circumferentially around the rotating circular rod.

[0012] A further improvement is that the connecting member includes two linkage rods arranged on the right end face of the moving block and located on the front and rear sides of the rotating round rod, two longitudinal grooves longitudinally opened on the front and rear end faces of the rotating round rod, and a linkage block with one end arranged on the linkage rod and the other end slidingly engaged with the longitudinal groove.

After the sludge settles again after standing for a period of time, the rotating plate is driven to rotate to a predetermined position in the rotating ring groove by the rotating device, so that the closing plate corresponds to the position of the pressure relief opening. At this time, the pressure relief opening is closed by the closing member, thereby separating the sludge at the bottom and the sewage in the upper layer. At this time, the settled sewage is discharged outward through the drain outlet, and the soil at the bottom is not easily discharged outward along with the flow of water, and is not easily affected by the discharge of the settled sewage.

[0017] Further effect: the screen can reduce the mud from flowing into the upper sewage from the pressure relief opening when the mud pressing plate presses on the settled mud.

[0018] Further effect: the annular scraper can also prevent the sludge from leaking from the gap between the circumference of the mud pressing plate and the inner wall of the sedimentation barrel when the mud pressing plate is located above the sludge, thereby improving the isolation and separation effect of the sludge.

[0019] Further effect: the push spring can push the closing slide plate to squeeze the inner wall of the closing plate in the closing chute, and the position of the pressure relief opening is blocked by the closing slide plate. BRIEF DESCRIPTION OF THE DRAWINGS

During discharge, the drain pipe can be connected to an external water pump, and the drain pipe is inserted into the drain port in the water holding chamber, and the upper layer of sewage is pumped out by the water pump.

[0029] A screen 13 is provided on the mud pressing disc 7 and located inside the pressure relief opening 8 .

[0030] The lower end surface of the sedimentation barrel 1 is provided with a glass observation window 14. The glass observation window 14 can facilitate the grasping of the descending position of the mud pressing plate in the sedimentation barrel 1. If the glass observation window 14 is not provided, the sedimentation barrel 1 can be set as a glass barrel.

[0031] An annular scraper 15 is provided on the circumference of the mud pressing plate 7 for dropping the sludge remaining on the inner wall of the sedimentation barrel 1 when the mud pressing plate 7 rises or falls in the sedimentation barrel 1 .

[0032] The lifting device includes a rotating screw 16 rotatably disposed between the mounting cover 3 and the sedimentation barrel 1 within the accommodating chamber, a reduction motor 17 whose fixed end is disposed on the mounting cover 3 and whose output end is connected to the rotating screw 16, and a rotating motor 18 disposed on the reduction motor 17 for driving the reduction motor 17 to rotate and thereby drive the rotating screw 16 to rotate.

A rotating cylinder rotatably mounted on the mounting cover 3 and located within the rotating circular hole 21. The arc-shaped waist hole 23 is concentrically arranged with the center point of the rotating circular hole 21 , and the upper end surface of the sliding connecting rod 24 is fixedly arranged on the lower end surface of the moving block 25 .

[0034] The connecting member includes two linkage rods 26 disposed on the right end surface of the moving block 25 and located on the front and rear sides of the rotating rod 22, two longitudinal grooves 27 longitudinally formed on the front and rear end surfaces of the rotating rod 22, and a linkage block 28, one end of which is disposed on the linkage rod 26 and the other end of which is slidably engaged with the longitudinal groove 27. When the moving block 25 moves circumferentially around the rotating rod 22, the linkage rod 26 drives the linkage block 28 to follow the moving block 25 in circumferential movement around the rotating circular hole 21, thereby driving the rotating circular rod 22 to rotate circumferentially together; when the mud pressing plate 7 is raised or lowered, the longitudinal grooves 27 and the linkage block 28 cooperate to enable the mud pressing plate 7 to drive the rotating circular rod 22 to rise or fall within the rotating circular hole 21.

[0035] The left end of the moving block 25 is provided with a driving plate 29 for pushing the moving block 25 to drive the sliding connecting rod 24 to slide in the arc-shaped waist hole 23 when driven by an external force. The driving plate 29 can be manually pushed in the circumferential direction, so that the moving block 25 drives the sliding connecting rod 24 to slide in the arc-shaped waist hole 23.

[0036] The upper end surface of the mounting cover 3 is provided with a telescopic cylinder 30. The fixed end of the telescopic cylinder 30 is provided on the upper end surface of the mounting cover 3. The output end of the telescopic cylinder 30 is hingedly connected to the drive plate 29. The extension and retraction of the telescopic cylinder 30 can be directly controlled to drive the drive plate 29 to push the movement of the moving block 25.

[0037] The closure member includes a closure chute 31 formed on the upper and lower ends of the closure plate 12, a closure slide 32 disposed on the closure plate 12 and positioned within the closure chute 31, and a push spring 33 disposed between the closure slide 32 and the closure plate 12 and positioned within the closure chute 31. The closure slide 32 is a rubber plate.

[0038] The working principle of the utility model is as follows: when it is necessary to discharge the sewage after the sedimentation in the device outward, the reduction motor 17 is driven to rotate by the rotating motor 18, and the rotating screw 16 is driven to rotate slowly by the reduction motor 17. In the process of the rotation of the rotating screw 16, the cooperation of the guide rod 19 and the guide hole 20 prevents the mud pressing plate 7 from rotating with the rotating screw 16, so that the mud pressing plate 7 slowly descends in the water holding chamber 2 until the mud pressing plate 7 is located above the sludge. The position of the mud pressing plate 7 can be confirmed through the observation window. In the process of the mud pressing plate 7 slowly descending, the pressure relief opening 8 can reduce the sludge settled at the bottom from being pushed by the water flow to the upper sewage. After the sludge settles again after standing for a period of time, the driving plate 29 is pushed in the circumferential direction manually or the telescopic cylinder 30 is used to push the driving plate 29, so that it drives the sliding joint on the moving block 25. The rod 24 slides in the arc-shaped waist hole 23, and the shape of the arc-shaped waist hole 23 causes the moving block 25 to make circumferential motion around the rotating circular hole 21. When the moving block 25 moves circumferentially, the linkage rod 26 drives the linkage block 28 to follow the moving block 25 to move circumferentially around the rotating circular hole 21, thereby driving the rotating circular rod 22 to rotate circumferentially together, thereby driving the rotating disk 11 to rotate until the closing plate 12 is located on the pressure relief opening 8. The pushing spring 33 can push the closing slide 32 to be squeezed on the inner wall of the closing plate 12 in the closing chute 31, and the position of the pressure relief opening 8 is blocked by the closing slide 32, thereby separating the sludge at the bottom and the sewage on the upper layer. At this time, the closing plug is removed from the drain outlet 5, and the settled sewage is discharged outward through the drain outlet 5. The mud at the bottom is not easily discharged outward along with the flow of water, and it is not easy to affect the discharge of the settled sewage.
