[0019] Beneficial effects:
[0020] I. This utility model provides a low-noise thickener. When the lifting device is activated, it can move the lifting plate up and down. When the lifting plate moves, it pulls the guide frame around the point hinged to the working bridge via a push-pull plate. In this way, the guide frame can be raised and lowered. When the guide frame is at its lowest point, the raw material enters the interior of the guide frame through the discharge port and moves along the guide frame toward the side wall of the thickener body. By changing the direction of movement of the raw material when it falls, the gravitational potential energy of the raw material when it falls into the thickener body is reduced, and the impact force of the raw material on the inner wall of the thickener body is reduced, thereby achieving the purpose of reducing noise.
[0021] II. The present invention provides a low-noise thickener, which changes the angle of the guide frame by means of a lifting device. The greater the downward angle of the guide frame, the shorter the displacement required before the raw material falls to the bottom of the thickener body, and the shorter the time required for the raw material to enter the thickener body. The angle of the guide frame can be adjusted by the lifting device, thereby adjusting the speed at which the raw material enters the thickener body. Attached Figure Description

[0028] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0029] like Figures 1-4As shown in the figure, the present invention provides a low-noise thickener, including a thickener body 1, support legs 2, and a working bridge 4. The support legs 2 are installed on the lower side of the thickener body 1, and the working bridge 4 is installed on the upper side of the thickener body 1. The support legs 2 are used to support the entire thickener body 1, while the working bridge 4 is used for workers to walk, making it convenient to observe the internal working conditions of the thickener body 1, and also to facilitate the maintenance, inspection, and feeding of the internal components of the thickener body 1. A stirring assembly 5 is provided inside the thickener body 1, which is used to stir the raw materials entering the thickener body 1, thereby accelerating the concentration speed of the raw materials.
[0030] For reference Figure 1 , Figure 2 The stirring assembly 5 includes a stirring shaft 501, stirring blades 502, inclined plate 503, upper support 504, and lower support 505. The stirring shaft 501 is inserted into the middle position of the concentrator body 1. The stirring blades 502 are installed at the bottom of the stirring shaft 501. The stirring blades 502 are inclined straight plates, and the shape of the inclined straight plates is the same as the cross-section of the bottom of the concentrator body 1, that is, the inclined straight plates are parallel to the cross-section of the bottom of the concentrator body 1.
[0031] In a specific embodiment, a plurality of inclined plates 503 are installed on the stirring blade 502. The inclined plates 503 are distributed at an incline. The stirring shaft 501 is movably connected to the upper support 504 and the stirring shaft 501 is movably connected to the lower support 505. The lower support 505 is located on the upper side of the stirring blade 502. The system also includes an upper bracket and a lower bracket. The upper support 504 is installed on the upper bracket, and the lower support 505 is installed on the lower bracket. The upper bracket is installed at the bottom of the working bridge 4, and the lower bracket is connected to the inner wall of the concentrator body 1.
[0032] To facilitate material feeding, a material cylinder 6 is provided on the lower side of the working bridge 4. The material cylinder 6 has several discharge ports 601. The material cylinder 6 is located at the position of the stirring shaft 501. The multiple discharge ports 601 are arranged in a circumferential array around the center line of the stirring shaft 501, so that the raw materials are sprinkled into the interior of the thickener body 1 through the multiple discharge ports 601.
[0033] In order to reduce the noise generated when the thiocyanate body 1 is working, a sound-absorbing panel 3 is attached to the outer wall of the thiocyanate body 1. The sound-absorbing panel 3 is made of fiberglass board material and is attached to the outer wall of the thiocyanate body 1 to reduce noise.
[0034] In order to reduce the noise caused by the large drop when the raw materials enter the thickener body 1, a noise reduction mechanism 7 is installed inside the thickener body 1.
[0035] In a specific embodiment, the noise reduction mechanism 7 includes a guide frame 701, a top plate 702, a push-pull plate 703, a lifting plate 704, and a lifting device 705. The guide frame 701 is movably installed at the bottom of the working bridge 4. The guide frame 701 includes a fan-shaped plate and an end plate. There are two end plates, and the two end plates are respectively installed at the two ends of the upper side of the fan-shaped plate. The guide frame 701 is aligned with the discharge port 601. There are multiple guide frames 701, and the multiple guide frames 701 are arranged in a circumferential array around the center line of the material cylinder 6.
[0036] More specifically, the top plate 702 is installed on the upper side of the guide frame 701. The top plate 702 is movably connected to the push-pull plate 703. The push-pull plate 703 is movably connected to the lifting plate 704. The lifting device 705 is connected to the lifting plate 704. The lifting device 705 is used to drive the lifting plate 704 to move up and down. The lifting device 705 can be a common hydraulic cylinder or electric telescopic rod. A support frame is provided on the outside of the lifting device 705. The lifting device 705 is inserted into the support frame. The support frame is installed on the working bridge 4.
[0037] When the lifting device 705 is activated, it drives the lifting plate 704 to move up and down. As the lifting plate 704 moves, it pulls the guide frame 701 around the point hinged to the working bridge 4 via the push-pull plate 703. This allows the guide frame 701 to rise and fall. When the guide frame 701 is at its lowest point, the raw material enters the interior of the guide frame 701 through the discharge port 601 and moves along the side of the guide frame 701 towards the side wall of the concentrator body 1. By changing the direction of the raw material's descent, the risk of it falling into the concentrator body is reduced. The gravitational potential energy inside the thickener body 1 reduces the impact force of the raw material on the inner wall of the thickener body 1, thereby reducing noise. The angle of the guide frame 701 is changed by the lifting device 705. The greater the downward angle of the guide frame 701, the shorter the displacement length required for the raw material to fall to the bottom of the thickener body 1, and the shorter the time required for the raw material to enter the thickener body 1. The angle of the guide frame 701 can be adjusted by the lifting device 705, thereby adjusting the speed at which the raw material enters the thickener body 1.
[0038] To ensure smoother movement of the lifting plate 704, a horizontal tube 706, a vertical tube, a slider 707, an inclined tube 708, and a track 709 are provided on the upper side of the lifting plate 704. The horizontal tube 706 is perpendicular to the vertical tube and is mounted on the upper side of the lifting plate 704. The vertical tube is mounted on the slider 707, and the inclined tube 708 is installed between the horizontal tube 706 and the vertical tube. The slider 707 slides on the track 709, which is vertically mounted on the working bridge 4. The slider 707, track 709, and other components guide the movement of the lifting plate 704.
[0039] In summary, this utility model embodiment provides a low-noise concentrator. When the lifting device 705 is activated, it drives the lifting plate 704 to move up and down. As the lifting plate 704 moves, it pulls the guide frame 701 around the point hinged to the working bridge 4 via the push-pull plate 703. This allows the guide frame 701 to rise and fall. When the guide frame 701 is at its lowest point, the raw material enters the interior of the guide frame 701 through the discharge port 601 and moves along the guide frame 701 towards the side wall of the concentrator body 1. This changes the movement of the raw material during its descent. The direction of the material guide frame 701 is adjusted to reduce the gravitational potential energy of the material falling into the thickener body 1, thereby reducing the impact force of the material on the inner wall of the thickener body 1 and thus reducing noise. The angle of the guide frame 701 is changed by the lifting device 705. The greater the downward angle of the guide frame 701, the shorter the displacement length required for the material to fall to the bottom of the thickener body 1, and the shorter the time required for the material to enter the thickener body 1. The angle of the guide frame 701 can be adjusted by the lifting device 705, thereby adjusting the speed at which the material enters the thickener body 1.

Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
