Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a tailings wet mud drying device. Background Art

[0002] Drying devices are common devices for treating wet mud and tailings in the field of environmental protection. They include vertical drying devices and cylindrical drying devices. They use technical means to remove moisture from wet mud and tailings before treatment, in preparation for later treatment. If the sludge is not dried, the material transportation process will not only cause pollution but also generate a lot of transportation costs.

[0003] The traditional way is to heat, dehumidify and dry by means of hot air furnace, etc. This method is relatively simple, but it consumes a lot of energy and causes great pollution to the environment.

[0004] The patent "Sludge Drying Box" (publication number CN209128298U, hereinafter referred to as prior art 1) discloses a drying box for sludge drying. In prior art 1, a filter cartridge is set in the drying box to dry the sludge in a green channel. A drying box is set to wrap and dry the filter cartridge part. A stirring component is set in the filter cartridge to fully dry the sludge. However, the filter cartridge in prior art 1 is suspended in the air, and the sludge itself carries a lot of water and dead weight. The suspended setting reduces its service life and is unsafe. Moreover, it is impossible to dry more sludge at the same time by drying with a suspended filter cartridge. In addition, the sludge is not fully stirred when passing through a single stirring shaft. There may be soil, stones or mesh in the sludge, which will also prevent it from working normally. When there is more sludge in the filter cartridge, its processing will proceed more slowly, and the quality and efficiency of the processing will be reduced. Utility Model Content

[0027] Example 1

[0028] See also Figure 1 The embodiment of the utility model provides a tailings wet mud drying device, comprising a chassis and a drying component arranged inside the chassis. The drying component is arranged inside the chassis, and generates heat inside the chassis to dry the tailings wet mud. The inside of the chassis is completely closed except for the feed inlet 35 and the steam outlet. The tailings wet mud conducts heat through contact with the drying component, thereby drying the tailings wet mud. In addition, the tailings wet mud can also be turned over and moved on the drying component.

[0029] The drying component is supported by the first bearing seat 21 and the second bearing seat 22 provided on both sides of the chassis. The drying component is set as a component for drying a large amount of tailings wet mud at the same time, and its own setting is enlarged and has a certain mass. A stable support is provided by the first bearing seat 21 and the second bearing seat 22. The drying component can fully exert its ability to dry a large amount of tailings wet mud at the same time. The chassis includes a first side plate 33 and a second side plate 34 provided on both sides, and the first side plate 33 and the second side plate 34 are used to assist in supporting the drying shaft 41 and install the first bearing seat 21 and the second bearing seat 22. The lower half and the upper half of the first side plate 33 and the second side plate 34 are respectively provided with a lower box body 31 and an upper box body 32, and the two ends of the lower box body 31 and the upper box body 32 are respectively combined on the inner walls of the first side plate 33 and the second side plate 34. The drying component is supported by the first bearing seat 21 and the second bearing seat 22 and is provided in the cavity formed between the lower box body 31 and the upper box body 32. The lower box body 31 and the upper box body 32 are both arranged in an arc-shaped plate shape, and a cavity is formed inside the lower box body 31 and the upper box body 32 after being combined. The drying component is dried inside the cavity. The wet mud tailings are accommodated in the cavity.

[0030] The frame 11 is arranged outside the lower box 31. Since the drying components, the lower box 31 and the upper box 32 have a certain weight and vibrate when working, in order to prevent the vibration generated during work from affecting the normal drying work, the frame 11 is arranged on the lower box 31, the upper box 32 and the machine body, and the lower box 31 and the upper box 32 are stabilized by the frame 11. The first side plate 33 and the second side plate 34 are fixed on both sides of the frame 11, and the first side plate 34 and the second side plate 34 are also stabilized again by the frame 11.

The first bearing seat 21 and the second bearing seat 22 are respectively arranged on the outside of the first side plate 33 and the second side plate 34, and fixed on the frame 11. After being fixed on the frame 11, the vibration and shaking generated by the first side plate 33 and the second side plate 34 can be transmitted to the ground, so that the overall operation of the equipment is stable. Since the tailings or wet mud have a certain weight when drying, the carrying capacity and drying capacity of the drying device need to be considered when setting the drying device. In addition, when working, the weight of the tailings or wet mud is added, and the drying device will generate a large inertia when rotating. In order to maintain the stability of the drying device, all its working parts are set on the frame 11 for fixing. Furthermore, in actual application, it is better to fix the drying device to the ground through the frame 11 to ensure that the stability of the drying device is stronger.
