Description

Technical Field

[0001] This application relates to the technical field of sludge treatment equipment, and in particular to a modular device for cleaning and removing sludge. Background Technology

[0002] Mechanical sludge removal is a crucial link in the entire sludge treatment system for waterworks. Its core objective is to effectively extract and recycle clean, appropriately sized sand through washing and screening processes. However, in current technological practices, while widely used spiral washing devices can achieve the basic functions of sludge treatment, they generally face significant drawbacks such as large footprint and complex equipment installation and maintenance processes. These shortcomings not only limit the improvement of treatment efficiency but also increase operating costs and space consumption. Therefore, there is an urgent need and ample room for improvement in the optimization and innovative design of sludge treatment devices. Utility Model Content

[0003] In view of the problems that existing sludge treatment devices generally have, such as large footprint, low processing efficiency and high mud content in fine sand, this application innovatively proposes a modular sludge cleaning device. Through the design of combining integration and modularization, it effectively integrates functions such as sludge cleaning, separation and fine sand recovery, which not only significantly improves the processing efficiency, but also ensures the low mud content of fine sand, while greatly reducing the footprint.

[0004] The technical solution adopted in this application is as follows:

[0005] A modular device for cleaning and removing sludge includes a lower housing and an upper housing mounted on the lower housing, with a material discharge channel connecting the upper and lower housings. The upper housing is equipped with a feed hopper and a cleaning and screening component. A coarse material discharge port communicating with the cleaning and screening component is opened on one side of the upper housing. A fine sand treatment component is installed in the lower housing, and a fine sand discharge port is provided on the side wall of the lower housing. Sludge enters the cleaning and screening component from the feed hopper for cleaning and screening. Large particles are discharged from the coarse material discharge port, while fine particles enter the fine sand treatment component through the material discharge channel for cleaning and are discharged through the fine sand discharge port.

[0006] By adopting the above technical solution, the stacked structure of the upper and lower boxes offers advantages such as small footprint and convenient installation. The washing and screening components first wash and screen the sludge; large particles such as stones can be discharged through the coarse material discharge port, while fine materials enter the lower box through the discharge channel and are processed by the sand washing and treatment components. Through modular design, it integrates functions such as sludge washing, separation, and fine sand recovery, enabling sludge treatment and offering advantages such as easy equipment movement and quick deployment.

[0007] Optionally, the washing and screening assembly includes a feeding component and a drum washing machine arranged in sequence. The outlet end of the drum washing machine is provided with a screen assembly. The end of the screen assembly is connected to the coarse material discharge port. The pores on the side wall of the screen assembly are located at the upper end of the material discharge channel. Coarse material is discharged from the coarse material discharge port through the screen assembly, and fine material is fed into the material discharge channel through the screen assembly.

[0008] By adopting the above technical solution, the mud and sludge are fed into the drum washing machine through the feeding component. The drum rotates continuously, and the mud and sludge rub against each other and are continuously lifted and thrown inside the drum, making it easier for the mud on the surface of the material to be removed and cleaned. Large particles such as stones are discharged from the coarse material discharge port, while fine sand and sewage with small particle size are discharged through the screen into the discharge channel and enter the lower box.

[0009] Optionally, the feeder is selected from a screw feeder.

[0010] By adopting the above technical solution, material feeding is convenient and the feeding is stable.

[0011] Optionally, the fine sand treatment component consists of a high-efficiency wheel bucket sand washing device and a fine sand dewatering and recovery device. The high-efficiency wheel bucket sand washing device has multiple independent sand washing areas. The fine sand and water from the material discharge channel first enter the high-efficiency wheel bucket sand washing device, and then are sent to the fine sand dewatering and recovery device through the high-efficiency wheel bucket sand washing device, and then discharged from the fine sand discharge port.

[0012] By adopting the above technical solution, the high-efficiency wheel bucket sand washing device has multiple sand washing areas, and the cleanliness of the washed sand can be ensured through multiple rounds of washing; then, it is dewatered and recycled through a fine sand dewatering and recovery device, and the resulting fine sand can be discharged from the fine sand discharge port, and the resulting fine sand has the advantages of low mud content.

[0013] Optionally, the high-efficiency wheel bucket sand washing device includes a water storage tank and a first wheel bucket sand washing machine and a second wheel bucket sand washing machine installed in the water storage tank. The water storage tank is equipped with a partition to separate the two sand washing spaces.

[0014] By adopting the above technical solution, the wheel bucket sand washing machine is set up with two parts. The first part separates the fine sand and sewage, and then the second wheel bucket sand washing machine washes the fine sand, so that the fine sand obtained later has a low mud content and is cleaner.

[0015] Optionally, the fine sand dewatering and recycling device includes a water collection tank disposed in the lower box, a dewatering screen located above the water collection tank, a sewage pump, and a fine sand return device connected to the sewage pump. The second-wheel bucket sand washer throws fine sand onto the dewatering screen. After being dewatered by the dewatering screen, the fine sand is sent to the fine sand discharge port. The sewage pump sends the water in the water collection tank into the fine sand return device for treatment, and then sends the fine sand to the dewatering screen through the fine sand return device.

[0016] By adopting the above technical solution, fine sand with low moisture content can be obtained through a dewatering screen, and the fine sand can be recovered through a fine sand return device, thereby improving the recovery effect of fine sand.

[0017] Optionally, both the upper and lower housings include a frame and a plate that can be detachably installed on the frame.

[0018] By adopting the above technical solution, the plate is installed on the frame and can be disassembled, which not only facilitates the installation and disassembly of the overall device, but also makes it convenient for staff to inspect and maintain the equipment.

[0019] Optionally, observation windows are provided on the side walls of the upper and lower housings.

[0020] By adopting the above technical solution, the internal working conditions can be easily observed through the observation window, thereby facilitating the monitoring of the working status by the staff.

[0021] Optionally, the frame includes multiple horizontal beams and vertical beams connected together, and the horizontal beams and vertical beams are detachably connected.

[0022] By adopting the above technical solution, the frame includes a detachable connection structure of horizontal and vertical beams. When the equipment inside the box needs major inspection or overhaul, the relevant equipment can be easily forked out or lifted out as a whole by disassembling the beams and plates, thus improving maintenance efficiency.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. The device adopts a modular design, integrating functions such as mud washing and separation, sand separation, sand washing, and dewatering. This allows for the separation of large stone particles and fine sand from the mud, facilitating subsequent recycling processes. Furthermore, the fine sand processed by this device has a low mud content and better cleaning effect, ensuring low mud content and high cleanliness of the fine sand, thus meeting high standards for recycling.

Sludge is fed into the upper chamber 1 through the feed hopper 4, and is first washed and screened by the washing and screening assembly 5, allowing large particles of stone to be discharged through the coarse material discharge port 6. A discharge channel 3 is also installed between the upper chamber 1 and the lower chamber 2, through which materials in the upper chamber 1 are fed into the lower chamber 2. That is, fine sand and wastewater washed by the washing and screening assembly 5 are fed into the lower chamber 2 through the discharge channel 3.

[0035] A fine sand discharge port 8 is provided on the side wall of the lower chamber 2. A fine sand processing component 7 is installed in the lower chamber 2. The sand enters the lower chamber 2 through the material discharge channel 3, and after being washed, separated, dehydrated and recycled by the fine sand processing component 7, the fine sand can be discharged through the fine sand discharge port 8, thereby collecting the washed and separated fine sand.

[0036] Reference Figure 1 and Figure 4 The washing and screening assembly 5 includes a feeder 51 and a drum washing machine 52 connected in sequence, with the feeder 51 and drum washing machine 52 distributed along the length of the upper housing 1. The feeder 51 is preferably a screw feeder, with its inlet located at the lower end of the feed hopper 4, allowing the sludge from the feed hopper 4 to be fed into the screw feeder and then into the drum washing machine 52. The drum in the drum washing machine 52 rotates continuously under the drive of an external power source, causing the sludge to be continuously lifted and thrown within the drum. The friction between the particles removes most of the surface sludge.
