Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge dewatering room. Background Technology

[0002] Sludge treatment is a crucial component of wastewater treatment plant operations. Sludge generated from wastewater treatment must undergo appropriate processing to achieve stabilization and harmlessness before it can be disposed of according to relevant standards and regulations. The main objectives of sludge treatment are: 1. To reduce the sludge's moisture content and volume, creating conditions for disposal and reducing disposal costs; 2. To reduce organic matter in the sludge, stabilizing it and preventing secondary pollution; 3. To reduce harmful substances in the sludge, ensuring it meets harmless and hygienic requirements; 4. To facilitate the comprehensive utilization of sludge, achieving environmental protection goals. Currently, sludge dewatering is mostly performed using sludge dewatering machines installed in dewatering rooms.

[0003] The prior art discloses a sludge dewatering machine. The specific principle is as follows: water-containing sludge intermittently falls onto the annular filter belt of the conveying device, moves to the top of the pad block via the annular filter belt, and then stops moving. At this time, the pressure block moves down in the sludge solidification ring under the drive of the plunger cylinder, squeezing the sludge clumps located in the sludge solidification ring. Through the squeezing of the pressure block, the water content of the sludge in the sludge solidification ring is reduced to less than 30%.

[0004] However, this type of sludge dewatering machine cannot operate continuously, and the annular filter belt needs to stop moving during the compression process, resulting in low sludge treatment efficiency. In addition, sludge tends to stick to the bottom of the pressing block, reducing the filtration effect. Utility Model Content

[0005] The purpose of this invention is to provide a sludge dewatering room, which aims to effectively improve sludge treatment efficiency and filter press effect during sludge dewatering.

[0006] To achieve the above objectives, this utility model provides a sludge dewatering room, including a dewatering room body and a screw conveyor. The screw conveyor is fixedly connected to the dewatering room body and is located on the lower left side of the dewatering room body. It also includes an auxiliary mechanism.

[0007] The auxiliary mechanism includes a processing box, a limiting plate, a mesh belt conveyor, a sludge extrusion block, a drain pipe, an adjusting screw, a threaded seat, a connecting device, a guiding device, and a guiding device. The processing box is located at the bottom of the dewatering chamber and cooperates with the discharge port of the screw conveyor. The limiting plate is fixedly connected to the processing box and located on both sides of the processing box. The mesh belt conveyor is fixedly connected to the processing box and located inside the processing box. The sludge extrusion block is located above the mesh belt conveyor. The drain pipe is threadedly connected to the processing box and located at the bottom of the processing box. The adjusting screw is detachably connected to the sludge extrusion block and located at the top of the sludge extrusion block. The threaded seat is fixedly connected to the processing box and threadedly connected to the adjusting screw, and located at the top of the processing box. The connecting device is located on the side of the processing box near the bottom of the adjusting screw. The guiding device is located on both sides of the sludge extrusion block. The guiding device is located on the discharge port side of the processing box.

[0008] The bottom of the sludge extrusion block is inclined and is positioned at a high position on the feed side of the mesh belt conveyor.

[0009] The connecting device includes a first connecting block and a second connecting block. The first connecting block is detachably connected to the sludge extrusion block and is located on the side of the sludge extrusion block near the adjusting screw. The second connecting block is detachably connected to the sludge extrusion block and is located on the side of the sludge extrusion block near the first connecting block.

[0010] The guiding device includes a first guide rod and a second guide rod. The first guide rod is threadedly connected to the sludge extrusion block and slidably connected to the top cover plate of the treatment tank, and is located on one side of the sludge extrusion block. The second guide rod is threadedly connected to the sludge extrusion block and slidably connected to the top cover plate of the treatment tank, and is located on the side of the sludge extrusion block away from the first guide rod.

[0011] The guiding device includes a first guide plate and a second guide plate. The first guide plate is fixedly connected to the processing box and slidably connected to the conveyor belt of the mesh belt conveyor, and is located on the discharge port side of the processing box. The second guide plate is fixedly connected to the processing box and slidably connected to the conveyor belt of the mesh belt conveyor, and is installed in a figure-eight shape with the first guide plate.

[0012] The auxiliary mechanism further includes a first ventilation plate and a second ventilation plate. The first ventilation plate is fixedly connected to the dehydration chamber body and is located on both sides of the dehydration chamber body; the second ventilation plate is fixedly connected to the dehydration chamber body and is located on both sides of the dehydration chamber body.

[0013] This utility model discloses a sludge dewatering chamber. A screw conveyor is installed on the lower left side of the chamber body. After installation, its outlet can slide into the inlet mounting slot of the treatment box. Limiting plates are installed on both sides of the treatment box. A mesh belt conveyor is installed inside the treatment box. A sludge extrusion block is located above the mesh belt conveyor, with its bottom inclined and positioned high on the feed side of the mesh belt conveyor. A drain pipe is installed at the bottom of the treatment box. An adjusting screw is connected to the sludge extrusion block via a connecting device. A threaded seat is installed on the top of the treatment box and threadedly engages with the adjusting screw. Guide devices are located on both sides of the sludge extrusion block, and a guide device is located on the discharge side of the treatment box. During sludge treatment, sludge is fed into a screw conveyor and then transported to the mesh belt of a mesh belt conveyor inside the treatment tank. The sludge is continuously conveyed and then discharged after being compressed and concentrated by sludge extrusion blocks, effectively improving the concentration efficiency. Because the bottom of the sludge extrusion blocks is inclined and positioned high on the feed side of the mesh belt conveyor, the sludge extrusion process is continuous. This allows the sludge extrusion blocks to continuously extrude sludge between the mesh belt conveyors, overcoming the problem of sludge adhering to the blocks after each extrusion in existing technologies. Consequently, during sludge dewatering, the sludge treatment efficiency and filtration effect can be effectively improved. Attached Figure Description

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Example 1:

[0023] like Figures 1 to 4 As shown, where Figure 1 This is a schematic diagram of the overall structure of the sludge dewatering room. Figure 2 This is a top view of the processing box 103. Figure 3 This is a schematic diagram of the sludge extrusion block 106. Figure 4 This is a schematic diagram of the adjusting screw 108. This utility model provides a sludge dewatering chamber, including a dewatering chamber body 101, a screw conveyor 102, and auxiliary mechanisms. The auxiliary mechanisms include a processing box 103, a limiting plate 104, a mesh belt conveyor 105, a sludge compression block 106, a drain pipe 107, an adjusting screw 108, a threaded seat 109, a connecting device, a guiding device, and a guiding device. The connecting device includes a first connecting block 110 and a second connecting block 111. The guiding device includes a first guide rod 112 and a second guide rod 113. The guiding device includes a first guide plate 114 and a second guide plate 115. The aforementioned solution can effectively improve sludge treatment efficiency and filtration effect during sludge dewatering. It is understood that the aforementioned solution can effectively improve sludge treatment efficiency and filtration effect.

[0024] In this embodiment, the screw conveyor 102 is fixedly connected to the dewatering chamber body 101 and is located on the lower left side of the dewatering chamber body 101. The housing of the screw conveyor 102 is installed in the mounting cavity of the dewatering chamber body 101 by bolts. After installation, when the processing box 103 is set, the mating cavity of the feed inlet on the left side of the processing box 103 can be embedded and mated with the discharge port of the screw conveyor 102. The screw conveyor 102 drives the screw auger to rotate through the reducer to transport sludge. The dewatering chamber body 101 is provided with a door for easy access to the interior and sludge removal.

[0025] The processing box 103 is located at the bottom of the dewatering chamber body 101 and cooperates with the discharge port of the screw conveyor 102. The limiting plate 104 is fixedly connected to the processing box 103 and is located on both sides of the processing box 103. The mesh belt conveyor 105 is fixedly connected to the processing box 103 and is located inside the processing box 103. The sludge extrusion block 106 is located above the mesh belt conveyor 105. The drain pipe 107 is threadedly connected to the processing box 103 and is located within the processing box. At the bottom of 103, the adjusting screw 108 is detachably connected to the sludge extrusion block 106 and is located at the top of the sludge extrusion block 106. The threaded seat 109 is fixedly connected to the treatment box 103 and threadedly connected to the adjusting screw 108, and is located at the top of the treatment box 103. The connecting device is located on the side of the treatment box 103 near the bottom of the adjusting screw 108. The guiding device is located on both sides of the sludge extrusion block 106 and on the discharge port side of the treatment box 103. The processing box 103 can be directly installed on the floor inside the dewatering chamber body 101. The limiting plate 104 is bolted to the processing box 103. The mesh belt conveyor 105 is bolted inside the processing box 103, with its conveying mesh belt as close as possible to the limiting plate 104 to reduce the fitting gap. The sludge extrusion block 106 is located above the conveying mesh belt of the mesh belt conveyor 105. The top threaded mounting part of the drain pipe 107 is directly installed in the threaded drain hole at the bottom of the processing box 103 for drainage. The bottom of the adjusting screw 108 is connected to the sludge extrusion block 106 through the connecting device. The threaded seat 109 has a T-shaped cross-section, and its internal threaded hole cooperates with the adjusting screw 108 and is bolted to the top cover plate of the processing box 103. The guiding device is located on both sides of the sludge extrusion block 106 for guiding the vertical movement of the sludge extrusion block 106. The guiding device is located on the discharge port side of the processing box 103 for guiding the sludge discharge.

[0026] The sludge extrusion block 106 has an inclined bottom surface and is positioned at a high level on the feed side of the mesh belt conveyor 105. The inclined bottom surface of the sludge extrusion block 106 facilitates continuous sludge extrusion, overcoming the problem of sludge adhering to the extrusion block after each extrusion in the prior art.

[0027] Secondly, the first connecting block 110 is detachably connected to the sludge squeezing block 106 and is located on the side of the sludge squeezing block 106 near the adjusting screw 108; the second connecting block 111 is detachably connected to the sludge squeezing block 106 and is located on the side of the sludge squeezing block 106 near the first connecting block 110. The first connecting block 110 and the second connecting block 111 are the same size and can be installed by bolts respectively. After the first connecting block 110 and the second connecting block 111 are installed together, they form a circular clamping cavity, which facilitates clamping the H-shaped shaft end at the bottom of the adjusting screw 108, but allows the adjusting screw 108 to rotate. That is, after the first connecting block 110 and the second connecting block 111 are installed, they do not press the adjusting screw 108 tightly, and the bottom of the adjusting screw 108 can also rotate within the mounting groove at the top of the sludge squeezing block 106.

[0028] Then, the first guide rod 112 is threadedly connected to the sludge extrusion block 106 and slidably connected to the top cover plate of the treatment box 103, and is located on one side of the sludge extrusion block 106; the second guide rod 113 is threadedly connected to the sludge extrusion block 106 and slidably connected to the top cover plate of the treatment box 103, and is located on the side of the sludge extrusion block 106 away from the first guide rod 112. The first guide rod 112 and the second guide rod 113 have the same size, and their bottom external threaded ends can be directly installed in the connecting threaded holes of the sludge extrusion block 106. Their upper optical shaft ends can be slidably engaged with the through holes on the top cover plate of the treatment box 103, and T-shaped linear sliding bearings are embedded in the through holes on the top cover plate of the treatment box 103.

[0029] Finally, the first guide plate 114 is fixedly connected to the treatment box 103 and slidably connected to the conveyor belt of the mesh belt conveyor 105, and is located on the discharge port side of the treatment box 103; the second guide plate 115 is fixedly connected to the treatment box 103 and slidably connected to the conveyor belt of the mesh belt conveyor 105, and is installed in a figure-eight shape with the first guide plate 114. The first guide plate 114 and the second guide plate 115 are the same size and are respectively installed on the discharge port side wall of the treatment box 103 by bolts. After installation, they form a figure-eight guiding structure to facilitate sludge discharge.

[0030] When using this invention to improve sludge treatment efficiency and filtration effect, during sludge treatment, the sludge is first fed into the screw conveyor 102, and then conveyed onto the conveyor belt of the mesh belt conveyor 105 inside the treatment box 103. The sludge is then continuously conveyed and concentrated by the sludge extrusion block 106 before being discharged. The drain pipe 107 drains the sludge, effectively improving the concentration efficiency. To adjust the vertical height of the sludge extrusion block 106, rotating the adjusting screw 108 will move the sludge extrusion block 106 vertically. Simultaneously, the first guide rod 112 and the second guide rod 113 guide the movement to ensure linearity. Furthermore, because the bottom of the sludge extrusion block 106 is inclined and positioned high on the feed side of the mesh belt conveyor 105, the forward extrusion of the sludge is a continuous process. The sludge extrusion block 106 can continuously extrude the sludge between the mesh belt conveyors 105, overcoming the problem of sludge adhering to the extrusion block after each extrusion in the prior art. This effectively improves the sludge treatment efficiency and filtration effect during sludge dewatering.

[0031] Example 2:

[0032] like Figure 5 As shown, where Figure 5 This is a schematic diagram of the overall structure of the sludge dewatering room. Based on the first embodiment, this utility model provides a sludge dewatering room, and the auxiliary mechanism further includes a first ventilation plate 201 and a second ventilation plate 202.

[0033] The first ventilation plate 201 is fixedly connected to the dehydration chamber body 101 and is located on both sides of the dehydration chamber body 101; the second ventilation plate 202 is fixedly connected to the dehydration chamber body 101 and is located on both sides of the dehydration chamber body 101. The first ventilation plate 201 and the second ventilation plate 202 are respectively installed on the ventilation openings of the dehydration chamber body 101 by bolts.

[0034] In this embodiment, by setting the first ventilation plate 201 and the second ventilation plate 202, good ventilation can be achieved inside and outside after the door on the dehydration chamber body 101 is closed, while protection can be provided to prevent animals from entering the interior.
