Description

Technical Field

[0001] This utility model relates to the field of river dredging technology, specifically to a device for dewatering and solidifying dredged sludge from river dredging. Background Technology

[0002] River dredging generally involves using mechanical equipment to remove silt deposited on the riverbed, thereby clearing the waterway. After the dredging vessel collects the silt, it needs to be further processed by a silt dewatering device to remove the water from the silt and separate the water from the impurities in the silt. This not only facilitates subsequent processing of the silt but also reduces the space and weight occupied by the silt.

[0003] Existing sludge dewatering and solidification devices typically use pressure filtration to dewater sludge. However, due to the diverse types of impurities inside the sludge at the bottom of the river, large-volume impurities can easily cause severe wear or jamming of the filter cylinder and spiral blades of the pressure filtration assembly, making it difficult to filter large-volume impurities in the sludge before pressure filtration. Utility Model Content

[0004] The purpose of this invention is to provide a device for dewatering and solidifying silt from river dredging, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A river dredging sludge dewatering and solidification device includes a flatbed truck and a filter press assembly, which is set on top of the flatbed truck. The filter press assembly includes a filter press chamber fixedly installed on top of the flatbed truck. A filter cylinder is fixedly installed inside the filter press chamber by a frame. A spiral filter press roller is rotatably connected inside the filter cylinder. The feeding assembly is located above the filter press assembly. The feeding assembly includes a feeding bin that is fixedly embedded in the upper surface of the filter press chamber. A conical partition plate is fixedly installed inside the feeding bin. Multiple through holes are equidistantly opened on the surface of the conical partition plate. The sewage pump is installed on the upper surface of the filter press chamber.

[0006] Furthermore, a bracket is fixedly installed on the upper surface of the cart, and a No. 1 motor is fixedly installed on the upper surface of the bracket. The output end of the No. 1 motor is connected to the spiral filter roller through a gearbox.

[0007] Furthermore, the filter press chamber has a discharge port on its lower surface, a water collection pipe is fixedly installed on its lower surface, and a three-way pipe is fixedly connected to one end of the water collection pipe.

[0008] Preferably, a protective shell is fixedly embedded in the inner surface of the feeding hopper, and a rotating shaft is rotatably connected to one end of the protective shell via a bearing, while a hollow rod is rotatably connected to the other end of the protective shell via a bearing.

[0009] Preferably, a chain drive assembly is connected between the rotating shaft and the hollow rod, and a second motor capable of driving the rotating shaft is fixedly installed on the outer surface of the feeding bin.

[0010] Preferably, a conical helical blade is fixedly installed on the outer surface of the hollow rod by a support rod, and the conical helical blade is movably fitted with the conical partition plate.

[0011] Preferably, the inlet end of the sewage pump is fixedly connected to one end of a tee pipe via a pipeline, a rotary joint fixedly installed on the upper surface of the protective shell and fixedly connected to the hollow rod, and the outlet end of the sewage pump is fixedly connected to one end of the rotary joint via a pipeline.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The operation of motor No. 2 causes the hollow rod to drive the conical spiral blades to rotate, which moves the sludge accumulated at the bottom of the conical spiral blades upward, increasing the contact surface between wastewater and sludge, and also increasing the filtration surface of the sludge, allowing the sludge to pass through the conical partition plate quickly.

[0013] 2. The sludge enters the filter cylinder from the feeding hopper. The No. 1 motor runs, driving the spiral filter roller to rotate and filter the sludge. The wastewater generated by the filter press is discharged into the water collection pipe. Part of it is used by the sewage pump, and the other part is directly discharged through the pipeline. The sludge that has been filtered and solidified is discharged from the discharge port.

[0014] 3. When the sewage pump operates, a portion of the wastewater is injected through the hollow rod onto the top of the conical partition plate to flush the sludge. This allows the sludge to quickly pass through the through holes, while large impurities are blocked by the conical partition plate. This process separates large impurities from the sludge, preventing them from causing severe wear or jamming to the filter cylinder and spiral filter roller. At the same time, the wastewater generated by the sludge filtration flushes the sludge inside the feeding hopper, accelerating the flow rate of the sludge and increasing the feeding speed.

[0017] 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.

[0018] Please see Figure 1-4 In this embodiment of the utility model, the river dredging sludge dewatering and solidification device includes a trolley 1, which facilitates the movement of the entire device. It also includes a filter press assembly 2, which is disposed above the trolley 1. The filter press assembly 2 includes a filter press chamber 201 fixedly installed above the trolley 1. A filter cylinder 202 is fixedly installed inside the filter press chamber 201 through a frame. A spiral filter press roller 203 is rotatably connected inside the filter cylinder 202. A feeding assembly 3 is disposed above the filter press assembly 2. The feeding assembly 3 includes a feeding bin 301 fixedly embedded in the upper surface of the filter press chamber 201. The feeding bin 301 is connected to the filter cylinder 202. A conical partition plate 302 is fixedly installed inside the feeding bin 301. Multiple through holes 303 are equidistantly opened on the surface of the conical partition plate 302. A sewage pump 4 is disposed on the upper surface of the filter press chamber 201.

[0019] Specifically, the sludge is poured into the feeding hopper 301, filtered, and then enters the filter press hopper 201. The filter press assembly 2 dewaters the sludge, and the sewage pump 4 injects a portion of the wastewater generated by the filter press into the feeding hopper 301 to flush the sludge and accelerate its flow and filtration speed. Example 1

[0020] like Figure 1 and Figure 2 As shown, in this embodiment, a bracket 101 is fixedly installed on the upper surface of the trolley 1, and a No. 1 motor 204 is fixedly installed on the upper surface of the bracket 101. The output end of the No. 1 motor 204 is connected to the spiral filter press roller 203 through a gearbox. A discharge port is opened on the lower surface of the filter press chamber 201, and a water collection pipe 205 is fixedly installed on the lower surface of the filter press chamber 201. One end of the water collection pipe 205 is fixedly connected to a three-way pipe 206.

[0021] In this embodiment, the sludge enters the filter cylinder 202 from the feeding hopper 301. The No. 1 motor 204 operates, driving the spiral filter roller 203 to rotate and filter the sludge. The wastewater generated by the filter press is discharged into the water collection pipe 205. Part of it is used by the sewage pump 4, and the other part is directly discharged through the pipeline. The sludge after filter pressing and solidification is discharged from the discharge port.

[0022] like Figure 2-4 As shown, in this embodiment, a protective shell 305 is fixedly embedded in the inner surface of the feeding bin 301. The protective shell 305 protects the chain drive assembly 308. A rotating shaft 306 is rotatably connected to one end of the protective shell 305 through a bearing, and a hollow rod 307 is rotatably connected to the other end of the protective shell 305 through a bearing. A chain drive assembly 308 is connected between the rotating shaft 306 and the hollow rod 307. A second motor 309 capable of driving the rotating shaft 306 to rotate is fixedly installed on the outer surface of the feeding bin 301.

[0023] In practice, the No. 2 motor 309 operates, driving the rotating shaft 306 to rotate. Through the transmission of the chain drive assembly 308, the hollow rod 307 rotates, providing power for the rotation of the conical spiral blade 304.

[0024] like Figure 1 and Figure 4 As shown, in this embodiment, the inlet end of the sewage pump 4 is fixedly connected to one end of the tee pipe 206 through a pipe, and a rotary joint 401 fixedly connected to the hollow rod 307 is fixedly installed on the upper surface of the protective shell 305. The outlet end of the sewage pump 4 is fixedly connected to one end of the rotary joint 401 through a pipe.

[0025] In practice, the sewage pump 4 operates, injecting a portion of wastewater through the hollow rod 307 into the area above the conical partition plate 302 to flush the sludge. This allows the sludge to quickly pass through the through hole 303, while large impurities are blocked by the conical partition plate 302. Thus, the sludge is filtered within the feeding hopper 301, separating large impurities to prevent them from causing severe wear or jamming to the filter cylinder 202 and the spiral filter roller 203. Simultaneously, the wastewater generated from the sludge filtration flushes the sludge inside the feeding hopper 301, accelerating the sludge flow and increasing the sludge feeding speed. Example 2

[0026] Based on Example 1, in order to compensate for the problem that sludge easily accumulates at the bottom of the conical partition plate 302 and is not easy to contact with wastewater.

[0027] like Figure 4 As shown, in this embodiment, a conical spiral blade 304 is fixedly installed on the outer surface of the hollow rod 307 by a support rod, and the conical spiral blade 304 is movably fitted with the conical partition plate 302.

[0028] In practice, the hollow rod 307 drives the conical spiral blade 304 to rotate, causing the sludge accumulated at the bottom of the conical spiral blade 304 to move upward, increasing the contact surface between wastewater and sludge, and also increasing the filtration surface of the sludge, so that the sludge can quickly pass through the conical partition plate 302.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. 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.
