Description

Technical Field

[0001] The utility model relates to the technical field of desulfurized gypsum processing equipment, in particular to a desulfurized gypsum dispersing device before transportation. Background Art

[0002] Coal-fired power plants produce flue gas containing sulfur dioxide. Desulfurization in the coal-fired power industry includes recyclable and non-recyclable methods. The recyclable method produces H2SO4 and SO2, and the non-recyclable method produces flue gas desulfurization gypsum. Limestone-based wet desulfurization technology is the most common method. The main components and chemical properties of desulfurized gypsum are similar to those of natural gypsum. It can replace natural gypsum as a cement retarder, soil conditioner, agricultural fertilizer, structural filler for embankment construction, etc., which is conducive to environmental protection and social sustainable development.

[0003] At present, desulfurization gypsum is produced synchronously with flue gas desulfurization, and has a certain moisture content, generally reaching 10% to 15%. Due to its high moisture content and strong viscosity, it is very easy to adhere together and form lumps during the production process of loading, lifting and transportation, causing material accumulation and blockage, affecting the normal progress of the production process. Utility Model Content

[0004] The utility model provides a desulfurized gypsum breaking device before transportation, which solves the problem that the traditional desulfurized gypsum is easy to adhere together and form blocks during the production process of loading, lifting and transportation due to high water content and strong viscosity, and is difficult to transport.

[0006] In the above technical solution, further, one end of each dividing plate is vertically hinged to the side wall of the box, and the other end is obliquely extended downward and suspended. An electric push rod is obliquely arranged at the bottom of the dividing plate. The telescopic end of one end of the electric push rod is vertically hinged to the first hinge seat arranged at the bottom of the dividing plate, and the fixed end of the other end of the electric push rod is vertically hinged to the second hinge seat arranged on the side wall of the box.

[0007] In the above technical solution, further, the breaking up mechanism includes a rotating shaft, a radial plate, and a second motor. Both ends of the rotating shaft are horizontally rotated by bearing seats arranged on two corresponding side walls of the box body. One end of the rotating shaft extends to the outside of the box body and is connected to the output shaft of the second motor arranged on the outer wall of the box body.

The rotating disk 43 is driven to rotate by the first motor 42, which drives the rotating shaft 47 to rotate eccentrically. During the eccentric rotation of the rotating shaft 47, the upper end of the swing rod 44 is driven to move up and down, and the lower end of the swing rod 44 drives the guide rod 41 to move up and down. The up and down movement of the guide rod 41 drives the cutter 3 to move up and down, and the desulfurized gypsum transported on the conveyor 2 is reciprocated and cut horizontally to achieve uniform cutting of the blocky desulfurized gypsum.

[0031] In this embodiment, see Figure 1 One end of each dividing plate 5 is vertically hinged to the side wall of the box body 1 through a hinge, and the other end is inclined and extended downward to be suspended. An electric push rod 51 is obliquely arranged at the bottom of the dividing plate 5. The telescopic end of one end of the electric push rod 51 is vertically hinged to the first hinge seat arranged at the bottom of the dividing plate 5, and the fixed end of the other end of the electric push rod 51 is vertically hinged to the second hinge seat arranged on the side wall of the box body 1.

On the one hand, the materials can be gathered in the middle for centralized dispersion, which can speed up the dispersion efficiency and make the materials more uniform. On the other hand, it can prevent the desulfurized gypsum from clogging the box.

[0032] In this embodiment, see Figure 2 The disintegration mechanism 6 includes a rotating shaft 61, a radial plate 62, and a second motor 63. Both ends of the rotating shaft 61 are supported for horizontal rotation by bearing seats arranged on two corresponding side walls of the box body 1. One end of the rotating shaft 61 extends to the outside of the box body 1 and is connected to the output shaft of the second motor 63 arranged on the outer wall of the box body 1. A plurality of radial plates 62 are arranged at intervals along the axial direction on the outer wall of the rotating shaft 61. The radial plates 62 are distributed in a circular array on the outer wall of the rotating shaft 61. The rotating shaft 61 is driven to rotate by the second motor 63.

[0034] In this embodiment, a plurality of dividing rods 52 are arranged at the suspended end of each dividing plate 5, and each dividing rod 52 is vertically offset from the radial plate 62 so that the radial plate 62 will not interfere with the dividing rod 52 during the vertical circular motion, and can automatically pass freely through the gap between two adjacent dividing rods 52 to crush and disperse the larger granular materials intercepted by the plurality of dividing rods 52.

[0035] In this embodiment, the conveyor 2 is an existing commercially available equipment, preferably a plate chain conveyor, and the cutter 3 can directly contact the metal conveyor belt surface of the plate chain conveyor to cut off the desulfurized gypsum to prevent the desulfurized gypsum from solidifying together and being difficult to break up due to incomplete cutting.

[0036] It can be known from the above technical scheme that when in use, the desulfurized gypsum is loaded from the loading end of the conveyor 2, and the desulfurized gypsum is transported to the bottom of the cutter 3 through the conveyor 2. The rotating disk 43 is driven to rotate by the first motor 42, driving the rotating shaft 47 to rotate eccentrically. During the eccentric rotation of the rotating shaft 47, the upper end of the swing rod 44 is driven to move up and down, and the lower end of the swing rod 44 drives the guide rod 41 to move up and down. The up and down movement of the guide rod 41 drives the cutter 3 to move up and down, reciprocating and transversely cutting the desulfurized gypsum transported on the conveyor 2, and the cut desulfurized gypsum is unloaded from the conveyor 2, enters the box 1 from the feed port 11, and falls on one of the dividing plates 5, and the smaller particles of desulfurized gypsum pass through The gaps between the dividing rods 52 fall to the bottom of the box body 1 and are discharged from the discharge port 12. The larger particles of desulfurized gypsum are intercepted by the dividing rods 52, and the rotating shaft 61 is driven to rotate by the second motor 63. The rotation of the rotating shaft 61 drives the radial plate 62 to rotate in a circle. The radial plate 62 passes through the gaps between the dividing rods 52 during the circular rotation, and the desulfurized gypsum intercepted on the dividing rods 52 is broken by the rotational force, or the stronger desulfurized gypsum is quickly lifted to another dividing plate 5, and the stronger desulfurized gypsum is cut into pieces by the saw teeth 621 on the radial plate 62 until the stronger desulfurized gypsum is broken into particles that can pass through the gaps between the dividing rods 52.
