SU915965A1 - Machine for flashing non-classified non-ore building materials - Google Patents

Description

The invention relates to the beneficiation of minerals, in particular, for washing non-metallic building materials, fluxes and ores.

It is known a device for washing gravel and rubble, including a drum with a spiral on the inside, loading and unloading cones, a water supply system for washing, a frame with support rollers, an actuator [1].

The drawbacks of the device are the lack of possibility to regulate the rinsing mode with changes in material contamination and machine productivity.

The closest technical solution to the present invention is a drum washer for washing contaminated material, including two concentrically located drums with spirals, a loading device, a blade elevator with a discharge cone, a system for supplying water to the washing, a frame with supporting

rollers, drive, while in both drums the spirals are made lerforated, and the spiral of the inner drum is double (2).

The disadvantage of this drum ⁵ washing is the lack of quality washing non -assimilated material containing clay impurities, including lump clay.

¹⁰ The purpose of the invention is to improve the quality of washing and the possibility of regulating the performance of the machine.

This goal is achieved by

¹⁵ that the loading device is made in the form of two concentrically arranged cones, while the inner cone is perforated, and the unloading cone of the elevator is mounted on an axis independent of the drums and is driven in the form of a water turbine located inside the unloading cone.

FIG. 1 shows the machine, a general view, with sections of the loading and unloading parts; in fig. 2 the same, top view.

The machine includes two concentrically located 5 retaining drums 1 and 2, loading: a device consisting of an outer solid cone 3 and an internal perforated cone 4. The unloading device, o, contains a blade elevator 5 and a cone rotating on the cantilever support 6. using the turbine 8 under the action of pressure jets of water, you-15 walking tangentially from nozzles 9, which are installed on the pipe through which water is supplied to the machine for washing the material. Drums assembled with loading and unloading devices, interchangeable spirals 10 th 11 by means of bandages 12, balancing roller rollers ”13 th fixed supports 14 are mounted on a rotary frame 15.

The frame with one end pivotally connected 25 with fixed supports 16, the other rests on the hydraulic cylinders 17, through which changes its angle of inclination. The drums are supported by roller 18; which is mounted on frame 30. The drive of the machine includes an electric motor 19, a gearbox 20, a shaft with supports 21, on which a driving sprocket 22 is mounted, which is engaged with the driven pin _{35. The} hydraulic actuator for changing the angle of the machine consists of a gear pump 24, an electric motor 25, a tank 26 oil hydraulic system and in autonomous distribution prispo- 27. hydraulic cylinders ₄₀ are pivotally connected to the supports 28. The supply of the wash water in the machine is carried through the pipe 29, which is mounted on bearing supports 30 and 31. ₍₅

The machine works as follows. The source material is fed into the inner cone 4 of the loading device of the machine, in which the separation of fines takes place. The small fraction wakes up through the holes in the outer cone 3- The helixes installed in both cones evenly feed the material into the washing drums: from the inner cone to the inner drum 2-, from the outer one into the outer drum 1, in which the fractions are flushed from contaminants.

During the rotation of the drums, the washed mass makes a cascade-waterfall movement, accompanied by intensive mixing of the material, as a result of which the impurities disintegrate and become suspended. Impurities washed in both drums in the form of sludge are removed from the spruce from the side of the loading device.

Water is supplied to the internal flushing drum under pressure through pipe 29. Water enters the external drum by gravity from the elevator 5- Water accumulates in the elevator due to its partial discharge from the internal drum and from nozzles 9, through which water is supplied to the turbine 8.

The speed of the backflow of water is regulated by changing the angle of the drums. Water consumption is set depending on the content of contaminants in the source material.

Separately washed in the drums material enters the general discharge device. The blades of the Elevator 5 material is unloaded on the discharge cone 7, which is removed from the machine. The rotational speed of the discharge cone 7 is adjusted by changing the head of the water jets flowing out of the nozzles using a crane installed in the pipe 29. The rotational speed of the cone is set depending on the grain composition of the material, the degree of contamination of the source material.

The invention has advantages over the known. It is possible to wash unclassified nonmetallic building materials with different clay contents and different physicomechanical properties of clay impurities without reducing the quality of washing by adjusting the capacity and, accordingly, the washing time. Since rinsing is carried out in countercurrent mode, additional rinsing and dewatering of the washed material at the rumble is not required, which generally leads to a decrease in the specific water consumption for rinsing.
