Problems solved by technology

[0004] Existing dredgers use dredging to remove the silt in the channel into the ship's cabin, and then transport it to the mud throwing area for solidification and other treatments to improve resource utilization. However, these dredged mud contains a large number of aquatic plants , which will lead to an increase in the cost of subsequent processing

Embodiment 1

[0028] Such as Figure 1-5 As shown, a dredging mud cleaning device includes a dredging pump 30, the dredging pump 30 is connected to the separation bucket 40 through the pipe body 10, the separation bucket 40 is placed in the base body 60, and there is a water chamber between the separation bucket 40 and the base body 60 62. The separation barrel 40 is driven to rotate by the motor 61 connected to its bottom. The motor 61 is placed in the base body 60. The separation holes 44 are arranged on the surface of the separation barrel 40. The deflectors 42 are symmetrically arranged in the barrel, and the deflectors 42 have a long arc. A first arc surface 42a and a short arc surface second arc surface 42b. The arc direction of the first arc surface 42a is opposite to that of the second arc surface 42b.

[0029] The present invention adopts the dredging pump 30 to extract the dredging mud produced in the channel dredging project so that it enters the separation barrel 40, and adopts...

Embodiment 2

[0039] Parts of the present invention are all coated with anti-corrosion and wear-resistant coatings, such as the inner and outer surfaces of the separation barrel 40, the surfaces of the pretreatment box 20, etc., and the anti-corrosion and wear-resistant coatings are prepared by the following steps:

[0040] Grind the glass flakes, titanium dioxide, aluminum oxide and light calcium carbonate for 0.5 h according to the formula, and set aside. Weigh a certain amount of water, dispersant, and film-forming aid into a beaker, and disperse on a magnetic stirrer at a low speed. Add a certain amount of p-chlorophenoxyacetic acid and silicone-modified epoxy emulsion, and disperse at a medium speed for about 60 minutes. Mix the mica powder ground for 0.5 h with the dispersed emulsion, and stir rapidly on a magnetic stirrer for 50 min. Add a defoamer, defoam with a low-speed mixer, and mix well to obtain a coating. The dispersant is SK-5040, the defoamer is PA-311, and the solid cont...

Embodiment 3

[0043] During actual work of the dredging mud cleaning device of the present invention: the mud water produced by dredging is sucked by using the dredging pump 30 to produce suction, and the mud water enters the pretreatment box 20 to remove most of the larger sundries, such as aquatic plants, branches, etc. , tree branches are cut for subsequent centrifugation, the mud water enters the buffer tank 70 to reduce its impact force and enters the separation barrel 40 for centrifugal solid-liquid separation. The cleared dredged mud can be obtained after the material is removed.

[0044] The dredging pumps used in the present invention include but are not limited to: the dual-purpose sand suction pump produced by Jindingnuo Pump Industry, the model is 200PN-24, as for the motor used in the present invention, it should be selected according to the actual dehydration requirements, which should be the standard in the field Those skilled in the art know that, and will not go into detail...

Abstract

The invention discloses a dredging mud cleaning device, which belongs to the technical field of environmental pollution treatment. The device includes a dredging pump connected to a separation barrel through a pipe body, the separation barrel is placed in a base, and there is water between the separation barrel and the base. chamber, the separation barrel is rotated by a motor connected to its bottom, the motor is placed in the base body, separation holes are set on the surface of the separation barrel, deflectors are symmetrically arranged in the barrel, and the deflector has a long arc surface, a first arc surface and a short arc surface. The arc surface is the second arc surface, and the arc direction of the first arc surface is opposite to that of the second arc surface. The device of the invention is used for removing aquatic plants and metal objects in dredging mud, overcomes resistance and quickly separates water and mud, and has high cleaning efficiency.

Description

technical field [0001] The invention belongs to the technical field of environmental pollution treatment, and in particular relates to a dredging mud cleaning device. Background technique [0002] Channel dredging is the use of dredgers or other tools to remove underwater sediment in channels. Channel dredging is one of the main means to develop channels, increase and maintain channel scale. The ancient dredging method is to dig out the sediment in the water with a long-handled bucket spoon on a boat (row, raft). Since the appearance of dredgers powered by steam engines in the 18th century, dredging equipment has achieved rapid development. The middle and lower reaches and estuary areas of some large rivers in the world often use dredging technology to maintain the water depth of the channel. With the increasing popularity of large dredgers in channel water depth maintenance, the requirements for the efficiency of dredging equipment are also getting higher and higher. ...
