Description
Technical Field
[0001] The utility model relates to the technical field of sludge stirring, in particular to a composite passivating agent sludge soil improving stirring device. Background Art
[0002] With the acceleration of industrialization, heavy metal pollution has become a global environmental problem. Silt soil, due to its high water content, low permeability, and high organic matter content, serves as a natural reservoir for heavy metal pollutants. Agitators play a key role in the application of composite passivators to silt soil improvement. However, existing agitators have several shortcomings. For example, some agitators lack optimal mixing performance, preventing the composite passivator from fully mixing with the silt soil, resulting in poor improvement results.
[0003] Chinese patent CN210085243U discloses an in-situ sludge solidification stirring device, including an excavator joint, a stirring head drive sleeve and a solidifying agent input pipe. The bottom of the stirring head drive sleeve is fixedly connected to a first hydraulic motor arranged along the length direction of the stirring head drive sleeve, and the output shaft of the first hydraulic motor is rotatably sealed and connected to the bottom of the stirring head drive sleeve. The lower end of the output shaft of the first hydraulic motor is fixedly connected to the first stirring head. Two second hydraulic motors arranged vertically in the length direction of the stirring head drive sleeve are provided on the upper side of the first hydraulic motor. A pair of stirring heads for stirring in the vertical direction and a stirring head for stirring in the horizontal direction are provided at the lower end of the stirring device. The patent provides a pair of stirring heads for stirring in the vertical direction and a stirring head for stirring in the horizontal direction, which can cooperate with each other to stir simultaneously from both vertical and horizontal directions, thereby enhancing the uniformity of stirring.
[0004] One existing stirring device in this prior art incorporates a pair of vertical stirring heads and a horizontal stirring head. This design, through the interaction of these two stirring heads, allows the composite passivator and silt mixture to be stirred both vertically and horizontally, improving mixing uniformity to a certain extent. During the stirring process, the vertical stirring head can penetrate deep into the mixture, stirring and mixing materials at different depths; the horizontal stirring head can stir the materials horizontally, expanding the stirring range and ensuring more complete contact between the composite passivator and silt. However, while this stirring method improves stirring efficiency to a certain extent, it still has significant limitations. The stirring heads in this stirring device are only capable of reciprocating or rotating in a specific direction; the stirring device itself cannot rotate. As a result, during the stirring process, the silt is restricted to moving along a fixed stirring path, preventing comprehensive and multi-angle mixing. Some silt may remain trapped in "dead spots" during stirring, preventing it from fully contacting the composite passivator, thus affecting the overall stirring effect and the quality of the improved product.

DETAILED DESCRIPTION
[0022] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.
[0023] Reference Figures 1-6 As shown, the present invention provides a composite passivator silt soil improvement and stirring device, comprising: a main body 1, the top of which is provided with a connector 11 capable of connecting to an excavator; a transmission 2, which is provided at the bottom of the main body 1; an auxiliary body 3, which is provided at the bottom of the transmission 2 and is capable of rotation, and the bottom of the auxiliary body 3 is provided with a stirring assembly 4 capable of stirring silt; the stirring assembly 4 includes two sets of first stirrers 41 arranged on both sides of the bottom of the transmission 2 and capable of rotation, and the stirring assembly 4 also includes a second stirrer 42 arranged at the bottom of the auxiliary body 3 and capable of rotation, a plurality of first spray pipes 411 distributed on the first stirrer 41, and a plurality of second spray pipes 421 distributed on the second stirrer 42. The first stirrer 41 and the second stirrer 42 both have cavities inside, the first spray pipe 411 extends into the cavity in the first stirrer 41, and the second spray pipe 421 extends into the cavity in the second stirrer 42.
[0024] When using this composite passivator silt soil improvement mixing device, first dock the connector 11 on the top of the main body 1 with an excavator. Using the excavator's power and operating functions, the mixing device is moved above the silt area to be improved and lowered into the silt. The transmission 2 transmits power to the auxiliary body 3, driving it to rotate. The rotation of the auxiliary body 3 drives the second agitator 42 at its bottom. Simultaneously, the first agitators 41 on either side of the bottom of the transmission 2 also begin to rotate. During the mixing process, the composite passivator is transported into the cavities within the first and second agitators 41, 42, and then evenly sprayed into the silt through the first and second spray pipes 411, 421, respectively. The first agitator 41 provides initial stirring to mix the composite passivator with the silt. The second agitator 42 rotates with the auxiliary body 3, further stirring the silt, ensuring full contact and reaction between the composite passivator and the silt, achieving comprehensive and in-depth improvement of the silt. This method of combining multiple mixers with spraying and stirring improves the efficiency and quality of sludge improvement, so that the improved sludge reaches the required performance indicators.
[0025] One end of the two first agitators 41 extends into the auxiliary body 3 and is connected to a first bevel gear 412. The top end of the second agitator 42 extends into the auxiliary body 3 and is connected to a second bevel gear 422, which meshes with the first bevel gear 412. The stirring assembly 4 also includes a first connecting shaft 43 vertically disposed in the auxiliary body 3. The bottom end of the first connecting shaft 43 is connected to a third bevel gear 431, which meshes with the two first bevel gears 412. The transmission 2 includes a housing disposed at the bottom end of the main body 1, and the first connecting shaft 43 extends into the housing of the transmission 2. Power is transmitted from the transmission 2 to the first connecting shaft 43, which drives the third bevel gear 431 at the bottom end to rotate. Since the third bevel gear 431 is engaged with the two first bevel gears 412 , power is evenly transmitted to the two first agitators 41 , causing the two first agitators 41 to rotate synchronously, and the second agitator 42 also rotates to start preliminary stirring of the sludge.
[0026] The transmission 2 also includes a gear ring 23 rotatably mounted within its housing. The bottom of the gear ring 23 is interconnected with the top of the auxiliary body 3, driving the auxiliary body 3 to rotate about its axis. The housing of the transmission 2 is mounted at the bottom of the main body 1. Several second gears 22 are also mounted within the housing of the transmission 2, meshing with the gear ring 23. A first gear 21 is rotatably mounted at the center of the transmission 2, meshing with the second gear 22. The first gear 21 is secured to one end of a first connecting shaft 43. A driving assembly 6 for driving the elements inside the transmission 2 to rotate is also provided on the outside of the main body 1. The driving assembly 6 includes a first rotating driving member 61 fixed to the outside of the main body 1. The output end of the first rotating driving member 61 is connected to the fourth bevel gear 611. The driving assembly 6 also includes a second connecting shaft 62 vertically arranged inside the main body 1 and extending to the transmission 2. One end of the second connecting shaft 62 is connected to the first gear 21, and the other end of the second connecting shaft 62 is connected to the fifth bevel gear 621. The fifth bevel gear 621 is meshed with the fourth bevel gear 611.
[0027] Start the first rotary drive member 61 outside the main body 1. The first rotary drive member 61 is preferably a hydraulic motor. The output end of the first rotary drive member 61 drives the fourth bevel gear 611 to rotate. Since the fourth bevel gear 611 is meshed with the fifth bevel gear 621, the fifth bevel gear 621 rotates accordingly, thereby driving the second connecting shaft 62 to rotate. The second connecting shaft 62 is connected to the first gear 21, and the first gear 21 rotates together with the second connecting shaft 62. When the first gear 21 rotates, it drives the several second gears 22 meshed with it to rotate. When the second gear 22 rotates, it drives the gear ring 23 meshed with it to rotate. The bottom of the gear ring 23 is interconnected with the top of the auxiliary body 3, so the rotation of the gear ring 23 drives the auxiliary body 3 to rotate around its own axis.
[0028] A spray pipe 5 for inputting the passivating agent into the first agitator 41 and the second agitator 42 is also provided inside the main body 1. The spray pipe 5 includes a main pipe 51 vertically arranged in the main body 1 and the auxiliary body 3. Two first auxiliary pipes 52 and second auxiliary pipes 53 are connected to the main pipe 51. The first auxiliary pipe extends to the two first agitators 41, and the second auxiliary pipe 53 extends to the second agitator 42. A sealer that can prevent leakage of the agent is also provided between the first auxiliary pipe 52 and the first agitator 41. A sealer that can prevent leakage of the agent is also provided between the second auxiliary pipe 53 and the second agitator 42. The sealer can be a sealed bearing.
[0029] The external composite passivator is introduced into the main conduit 51 of the spraying pipeline 5 through a specific delivery pipe. The main conduit 51 guides the passivator into the stirring device, where it flows into two first and second sub-conduits 52 and 53. The first sub-conduits 52 deliver the passivator to the internal cavities of the two first agitators 41, while the second sub-conduits 53 deliver the passivator to the internal cavity of the second agitator 42. As the first and second agitators 41 and 42 rotate, the passivator in their internal cavities is sprayed into the sludge through the first and second spraying pipes 411 and 421, respectively.
[0030] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
