Description

Technical Field

[0001] The utility model relates to the field of extraction equipment structures, and particularly relates to a selective extraction device for polluted sediment. Background Technique

[0002] Organic particles such as rotting garbage, fish feces, fertilizers, dead algae, and wastewater discharge in water bodies sink to the bottom, and together with dead organisms after fermentation and decomposition, they mix with sediment at the bottom to form sediment. A certain thickness of sediment can play a role in supplying fertilizer, retaining fertilizer, and regulating and buffering sudden changes in water quality. However, too thick sediment or deteriorated bottom quality can cause serious harm to water quality and aquatic animals and plants. When the concentration of organic substances in the bottom is too high, it is conducive to the formation of anaerobic conditions at the bottom, leading to the production of toxic metabolites by microorganisms, and the increase of harmful substances such as ammonia nitrogen and nitrite, further exacerbating the blackening and stinking of the sediment, water quality deterioration, and the large reproduction of parasites and germs. To improve the water quality of the water body, the sediment needs to be cleaned up.

[0003] In the prior art, for the cleaning of water body sediment, generally, the sediment is pumped up and transferred by a pump. However, this method will suck away solid substances such as bottom sand in the water body at the same time. Not only is the workload large, but it also makes it difficult for beneficial microorganisms at the bottom of the water body to take root, resulting in a long time for the water body to improve, and it is inconvenient to use. Therefore, we disclose a selective extraction device for polluted sediment to meet people's needs. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] Embodiment: Refer to Figures 1-4 A selective extraction device for contaminated bottom mud shown in the figure, including an outer cylinder cover 1, a sealing cover 3 is installed on the top side of the outer cylinder cover 1, a motor 9 is installed on the inner wall of the top side of the sealing cover 3, an avoidance hole is opened on the top side of the outer cylinder cover 1, the output shaft of the motor 9 passes through the avoidance hole and extends to the inside of the outer cylinder cover 1, a disc 11 is sleeved and installed on the output shaft of the motor 9, a plurality of fixed strips 12 are uniformly installed on the bottom side of the disc 11, a water outlet 5 is installed on the top side of the outer cylinder cover 1 on one side of the sealing cover 3, a hose 6 is sleeved and installed on the water outlet 5, and a telescopic rod 4 is installed on the top side of the sealing cover 3.

[0023] Based on the above structure, the outer cylinder cover 1 is extended into the bottom of the water through the telescopic rod 4 and covers the bottom mud to form a relatively airtight space. The motor 9 rotates to drive the disc 11 and multiple fixing bars 12 to rotate, thereby stirring the bottom mud, causing the organic matter in the bottom mud to rise. One end of the hose 6 is connected to a water pump, and the suspended pollutants and organic matter in the bottom mud are pumped out by the water pump, while the large-particle inorganic particles with larger mass settle in place and cover, achieving the selective removal of organic pollutants in the bottom mud, accurately removing the organic matter in the bottom mud. The outer cylinder cover 1 can, to a certain extent, prevent the problem of the deep bottom mud being disturbed by the environment and causing pollution to the water body. At the same time, compared with traditional dredging, the amount of sludge generated is less, the disturbance to the water environment is small, and it is convenient and fast to use.

[0024] The multiple fixing bars 12 are all made of elastic steel and have a certain deformation ability. In this way, when the fixing bars 12 rotate, they have a certain amount of deformation, preventing the rotation from being blocked when hitting the solid objects at the bottom of the water body and affecting the normal stirring.

[0025] As Figure 2 shown, water baffle plates 13 are installed on the multiple fixing bars 12. Through the setting of the water baffle plates 13, when the fixing bars 12 rotate, the water baffle plates 13 can intensify the flow of the water body, making the organic matter better mix with the water and rise.

[0026] As Figure 1 and 2 shown, an inner cylinder 2 is provided inside the outer cylinder cover 1. The outer side wall of the inner cylinder 2 matches the inner side wall of the outer cylinder cover 1. A fixing seat 14 is installed at the bottom end of the inner cylinder 2, a sliding rod 7 is installed on the top side of the fixing seat 14, a sliding sleeve 15 is installed on the outer side wall of the outer cylinder cover 1, the sliding rod 7 is slidably installed in the sliding sleeve 15, and an elastic unit is installed at one end of the sliding rod 7. Through the setting of the inner cylinder 2, the distance between the bottom end of the fixing bar 12 and the bottom mud can be adjusted by the telescopic movement of the inner cylinder 2, so as to adjust the position of the fixing bar 12 according to the hardness of the bottom mud.

One end of the tension spring 8 is connected to the bottom side of the limit block 16, and the other end is connected to the top side of the sliding sleeve 15. Through the setting of the tension spring 8, the tension of the tension spring 8 pulls the sliding rod 7 to move downward along the sliding sleeve 15 and drives the inner cylinder 2 to move downward. When a downward pressure is applied to the outer cylinder cover 1, the extended length of the inner cylinder 2 can be adjusted.

An avoidance opening for avoiding the output shaft of the motor 9 is provided on the filter net 10. The water outlet 5 is located at the top side position of the filter net 10. Through the setting of the filter net 10, the large-particle solid objects are blocked on the lower side of the filter net 10, so as to better pump out the rising substances.

[0029] As Figure 4 shown, a sealing ring 17 is sleeved on the output shaft of the motor 9, and the outer side wall of the sealing ring 17 matches the hole wall of the avoidance hole on the outer cylinder cover 1. By setting the sealing ring 17, the sealing performance of the sealing cover 3 can be better improved, which is beneficial to enhancing the waterproof performance of the motor 9.

[0030] Working principle of the present utility model:

[0031] The outer cylinder cover 1 is extended into the bottom of the water and covered on the bottom mud through the telescopic rod 4 to form a relatively airtight space. The motor 9 rotates to drive the disc 11 and multiple fixing bars 12 to rotate, thereby stirring the bottom mud to make the organic matter in the bottom mud float up. One end of the hose 6 is connected to a water pump, and the suspended polluted substances and organic matter in the bottom mud are pumped out through the water pump, while the large-particle inorganic particles with larger mass settle in place and cover, achieving selective removal of the organic polluted substances in the bottom mud, accurately removing the organic matter in the bottom mud. The outer cylinder cover 1 can, to a certain extent, prevent the problem that the deep bottom mud is disturbed by the environment and causes pollution to the water body. At the same time, compared with traditional dredging, the amount of silt generated is less, the disturbance to the water environment is small, and it is convenient and fast to use.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
