Figure 1 shows the device, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 1; figure 4 - section bb In figure 1.

The channel cleaning device consists of a housing 1 made with a movable bottom 2, a slurry line 3, at the lower end of which a diffuser 4 is installed, a pulp outlet 5 with a thickened part (thickening) 6 and a conical nozzle 7 installed coaxially, resulting in and a diffuser 4 is formed annular gap. At the suction end of the pulp exhaust 5, the supporting disk 8 with holes for the passage of water is rigidly fixed relative to the latter.

The thickening 6 of the pulp exhaust 5 with a spring 9, one end fixed on the conical nozzle 7 and the other on the support ring 10 installed in the upper part of the hydraulic ripper 11, which is rigidly connected to the bottom 2 of the housing 1, covers the pulp drain and is installed on the same axis as them with the possibility of coaxial movement. In the upper part of the hydrofluid disperser 11 there are windows 12 for the passage of water, and at the suction end of the pulp discharger 5 there are nozzles 13 of the hydraulic ripper 11.

On the inside surface of the bottom

2, guides 14 with threaded through holes 15 are fastened. Screws 16 are installed in holes 15,

the upper ends of which pass through the holes in the lid 17 of the housing 1, and the gears 18, which are in engagement with the gear wheel 19, are fixed to them. The gear wheel 19 is fixed in the lower part of the hollow cylinder 20 surrounding the slurry-rod 3. The cover 17 has a casing 21 It is replicated with the screw 22, the hollow cylinder 20 being provided with handles 23. The housing 1 has a port 24. I

The device for cleaning the channels works as follows.

The suction end of the pulp exhaust 5 is lowered under the water level in the channel, which requires cleaning from sediment.

When you turn on the working pump (not 0 shown) water through the pipe 24 enters the cavity of the housing. Then the water passes through the annular gap, enters the cavity of the slurry line 3, goes to discharge. Cleaning device5

The channel channels are lowered until the suction end of the pulp exhaust 5 resists sediment at the bottom of the channel. The spring 9 is then stretched, the diffuser 4 is lowered and closes the annular gap. The water in the pulpwater 3 will cease to receive energy in connection with the overlapping of the annular flow from the annular gap and under its own weight will be drained into the pulp drain.

5, thereby displacing the air that is located in the cavity of the pulp exhaust 5 between the annular gap and the water level in the channel, and since the suction end of the pulp exhaust 5 abuts the sediment, water has nowhere to drain from the pulp exhaust 5. Thus, the ejector will be charged.

At the same time, water from the hull through windows 12 for passing water through

annular cavity formed by hydroripper 11, nozzle 13 and bullets51

wastewater 5, enters the erosion of sediment. At the same time, nozzles 13 as close as possible to the sediment layer. The loosening process continues until the sediments are loosened, while pulping 5 with thickened part 6 and conical nozzle 7. under the action of spring 9 lowers, the annular gap opens, windows 12 for water flow will overlap with lowering thickening 6 of pulpo 5, loosening process the process of pulp pumping from the bottom of the channels will stop and immediately begin.

The operation of the device for cleaning the channels is controlled manually on the operating unit by turning the knobs 23 mounted on the hollow cylinder 20 around the slurry line 3. The gear wheel 19 causes the gears 18 and associated screws 16 to rotate, which, in conjunction with the threads the guides 14 raise or lower the bottom 2 of the body 1 and the pulpootvo 11.

yes 5 with a thickening 6 and a conical nozzle 7. Moving the conical nozzle 7 up or down leads to a change in the width of the annular gap, which makes it possible to change the mode of operation of the device.
