Description

Technical Field

[0001] This utility model relates to the field of sludge filtration technology, specifically a single-spiral sludge extrusion filtration and screening machine. Background Technology

[0002] Before dewatering, sludge needs to be filtered to remove large particles and solids, preventing damage to the filter structure in the dewatering equipment during subsequent dewatering by squeezing.

[0003] Currently, the main method used is to transport and compress sludge using a screw conveyor, which then filters the sludge through a filter screen to remove large particles and solid matter. During use, the filter screen needs to be disassembled and cleaned regularly to ensure the filtration effect and prevent sludge clogging. However, the sludge filtration process needs to be paused during the disassembly and cleaning of the filter screen, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a single-spiral sludge extrusion filter screen to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-spiral sludge extrusion filter screen, comprising: a tank, a feed pipe connected to the inner wall of one side of the tank, and a spiral rod rotatably mounted on the outer wall of the top of the tank; further comprising: a first motor mounted on the outer wall of the top of the tank, the output shaft of the first motor being connected to the spiral rod, and a rotating assembly mounted on the outer wall of one side of the tank; a transmission assembly mounted on the outer wall of the spiral rod, and the spiral rod being connected to the rotating assembly via the transmission assembly; an impact assembly mounted on the outer wall of one side of the tank, and an electric rotating platform mounted on the outer wall of one side of the tank; an extension plate mounted on the outer wall of one side of the tank, and a rotating rod rotatably mounted on the extension plate; a fixed box mounted at the bottom of the rotating rod, and filter assemblies mounted at both ends inside the fixed box.

[0006] The rotating assembly includes a connecting plate, a rotating column rotatably mounted on the top of the connecting plate, and an arc-shaped cover fixed to the bottom of the rotating column.

[0007] The transmission assembly includes a driving wheel mounted on the outer wall of the auger, a driven wheel mounted on the outer wall of the rotating column, and a belt connecting the driving wheel and the driven wheel.

[0008] The impact assembly includes a fixed plate, a fixing opening at one end of the top outer wall of the fixed plate, a long rod passing through the fixing opening, a ball installed at the bottom of the long rod, an arc-shaped plate fixed at the top of the long rod, and a first spring sleeved on the outside of the long rod.

[0009] The filter assembly includes a second motor, a flip rod connected to the output shaft of the second motor, a filter box fixed to one end of the flip rod, multiple equidistant second springs fixed to the inner wall of the bottom of the filter box, and a filter screen installed on the top of the second springs.

[0010] The flipping rod is rotatably connected to the inner wall of the fixed box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model discloses a single-spiral sludge extrusion filter screen, which features two filter components that can be used alternately and interchangeably. This allows for the cleaning of large particles and solids without interrupting the sludge filtration process. Used filter components can be flipped over during the interchange process, with their filter surfaces facing downwards. As the spiral rod rotates and transports sludge, the transmission and rotation components drive the impact component to move up and down, providing moderate impact to the used filter components. This causes large particles and solids to fall off the filter components, achieving automatic cleaning of the filtered material and making the process more convenient. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a single-spiral sludge extrusion filter screen, comprising: a tank 1, a feed pipe 2 connected to the inner wall of one side of the tank 1, and a spiral rod 3 rotatably mounted on the outer wall of the top of the tank 1. It also includes: a first motor 4 mounted on the outer wall of the top of the tank 1, the output shaft of the first motor 4 being connected to the spiral rod 3; a rotating assembly 5 mounted on the outer wall of one side of the tank 1; a transmission assembly 6 mounted on the outer wall of the spiral rod 3; and the spiral rod 3 being connected to the rotating assembly 5 via the transmission assembly 6. An impact assembly 7 is mounted on the outer wall of one side of the tank 1, and an electric rotating platform 8 is mounted on the outer wall of one side of the tank 1. An extension plate 9 is mounted on the outer wall of one side of the tank 1, and a rotating rod 10 is rotatably mounted on the extension plate 9. A fixed box 12 is mounted at the bottom of the rotating rod 10, and filter assemblies 11 are mounted at both ends inside the fixed box 12.

[0022] It should be noted that: sludge enters the tank 1 through the feed pipe 2. The first motor 4 drives the screw rod 3 to rotate, uniformly and continuously conveying the sludge downwards. As the sludge is conveyed into the tank 1, the space at the bottom decreases, and during the conveying process, it is squeezed through one of the filter components 11, thus filtering the sludge. After filtration, the sludge is discharged, while large particles and solid matter remain in this filter component 11. When it is necessary to clean the large particles and solid matter in this filter component 11, the bottom valve of the tank 1 can be temporarily closed, and the electric rotary table 8 can drive the rotating rod 10 to rotate 180° to clean the two filter components 11. 1. By swapping positions, the valve can be opened again to use another filter assembly 11 for filtration without interrupting the sludge filtration process. During the swapping process, the used filter assembly 11 can rotate and flip, so that its filter surface faces downwards. This allows large particles and solid matter to fall off automatically under the influence of gravity. At the same time, the screw rod 3 can drive the rotating assembly 5 to rotate through the transmission assembly 6. The rotation of the rotating assembly 5 can drive the impact assembly 7 to move up and down, moderately impacting the used filter assembly 11 and accelerating the falling speed of large particles and solid matter. This achieves automatic cleaning of the filtered material, making it more convenient.

[0023] In a preferred embodiment, the rotating assembly 5 includes a connecting plate 501, a rotating column 502 rotatably mounted on the top of the connecting plate 501, and an arc-shaped cover 503 fixed to the bottom of the rotating column 502.

[0024] It should be noted that during the rotation of the screw rod 3, the rotating column 502 can be driven to rotate through the transmission component 6, which in turn drives the arc-shaped cover 503 to rotate. Due to the undulating arc-shaped structure at the bottom of the arc-shaped cover 503, the arc-shaped cover 503 can drive the impact component 7 to move up and down during the rotation.

[0025] In a preferred embodiment, the transmission assembly 6 includes a drive wheel 601 mounted on the outer wall of the screw rod 3, a driven wheel 602 mounted on the outer wall of the rotating column 502, and a belt 603 that drives the drive wheel 601 and the driven wheel 602.

[0026] It should be noted that during the rotation of the screw rod 3, it can drive the driving wheel 601 to rotate, which in turn drives the belt 603 and the driven wheel 602 to rotate, which in turn drives the rotating column 502 to rotate.

[0027] In a preferred embodiment, the impact assembly 7 includes a fixing plate 701, a fixing opening at one end of the top outer wall of the fixing plate 701, a long rod 702 passing through the fixing opening, a ball 703 installed at the bottom of the long rod 702, an arc-shaped plate 704 fixed at the top of the long rod 702, and a first spring 705 sleeved on the outside of the long rod 702.

[0028] It should be noted that during the rotation of the arc-shaped cover 503, the arc-shaped protrusion on the bottom outer wall can press the arc-shaped plate 704 downward, thereby causing the long rod 702 to descend. The ball 703 can then strike the filter assembly 11 and compress the first spring 705. Subsequently, the first spring 705 drives the arc-shaped plate 704 to rise and reset. As the arc-shaped cover 503 rotates, the arc-shaped plate 704 descends again, forming a cycle.

[0029] In a preferred embodiment, the filter assembly 11 includes a second motor 1101, a flip rod 1102 connected to the output shaft of the second motor 1101, a filter box 1103 fixed to one end of the flip rod 1102, a plurality of equidistant second springs 1104 fixed to the bottom inner wall of the filter box 1103, and a filter screen 1105 installed on the top of the second springs 1104.

[0030] It should be noted that: the sludge in tank 1 is conveyed downward to filter box 1103. The sludge is continuously conveyed downward, compressing the sludge in filter box 1103. At this time, the sludge can be filtered through filter screen 1105. Large particles and solid matter are intercepted by filter screen 1105. When replacing the two filter boxes 1103, the used filter box 1103 can be rotated 180° by the second motor 1101 during the replacement process, so that the filter surface of filter screen 1105 faces downward, and the intercepted large particles and solid matter will fall off automatically under the influence of gravity.

[0031] Working principle: Sludge enters tank 1 through feed pipe 2. At this time, the first motor 4 drives the screw rod 3 to rotate, and the sludge is conveyed downward evenly and continuously. The sludge in tank 1 is conveyed downward to filter box 1103. The sludge is continuously conveyed downward, squeezing the sludge in filter box 1103. At this time, the sludge can be filtered through filter screen 1105. Large particles and solids are intercepted through filter screen 1105. When it is necessary to clean the large particles and solids intercepted on filter screen 1105 after a period of use, the valve at the bottom of tank 1 can be temporarily closed. The electric rotary table 8 drives the rotating rod 10 to rotate 180° to exchange the positions of the two filter boxes 1103. Then the valve is opened, and the filter screen 1105 in the other filter box 1103 is used to filter the sludge.

[0032] During the replacement process, the corresponding second motor 1101 drives the used filter box 1103 to rotate 180°, so that the filter screen 1105 faces downwards. This allows the intercepted large particles and solid matter to fall off automatically under the influence of gravity. During the rotation of the spiral rod 3, the drive wheel 601 can rotate, which in turn drives the belt 603 and the driven wheel 602 to rotate, which in turn drives the rotating column 502 to rotate. During the rotation of the arc-shaped cover 503, the arc-shaped protrusion structure on its bottom outer wall can press the arc-shaped plate 704 downwards, which in turn drives the long rod 702 to descend and squeeze the first spring 705. Then, the first spring 705 drives the arc-shaped plate 704 to rise and reset. As the arc-shaped cover 503 rotates, the arc-shaped plate 704 descends again, forming a cycle. The ball 703 can hit the used filter screen 1105 to accelerate the falling speed of large particles and solid matter, realizing automatic cleaning of the filtered materials, which is more convenient.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
