Abstract

The utility model relates to spinning production of the textile industry, can be used as part of a baking and cleaning unit and can improve the cleaning efficiency of the processed material. A pneumatic suction nozzle is installed in the baking powder in front of the output channel, a part of the cleaning surface of the knife drum located opposite the pneumatic suction nozzle is covered by a concentrically placed perforated sheet on a 15-20 mm wiring, while the arc length of the drum cleaning surface, covered by the grate, refers to the arc length of the cleaning surface a drum covered by a perforated sheet as 2; 1.

Description

The utility model relates to spinning production of the textile industry and can be used as part of a baking and cleaning unit.

Known cleaning and dedusting machine for cotton [1], containing the frame installed in the casing horizontally and parallel to each other two grate drums, the surface of the lower sector of which covers the grate, and made in the casing inlet and outlet for the movement of cotton. Above the ring drums, a perforated sheet is placed concentrically on a 15-20 mm wiring to form a vacuum chamber.

The disadvantage of the design is that the loosening of cotton is carried out in a free state, which does not allow to achieve the desired effect.

For the prototype taken loosening machine [2] (horizontal baking powder GR-8), containing the skeleton, located above it closed by the casing of the working area, equipped with a pair of feed cylinders and output channels for cotton movement. A knife drum is horizontally located in the working area. The surface of the knife drum from the supply cylinders to the outlet channel covers the grate, separating the working area from the carbon chamber.

However, this design does not ensure the removal of dust, lint and small weed impurities that remain in the processed material.

The technical result of the claimed utility model is to increase the cleaning efficiency of the processed cotton.

The specified technical result is achieved by the fact that in the dust-removing horizontal baking powder for cotton containing the skeleton, located

above it a closed working area equipped with a knife drum with a grate, a pair of feed cylinders, an output channel, according to a utility model, an air suction pipe is installed in front of the output channel, a part of the cleaning surface of the knife drum located opposite the pneumatic suction pipe is covered by a concentrically placed perforated sheet for wiring 15-20 mm, while the arc length of the cleaning surface of the drum, covered by the grate, refers to the length of the arc of the cleaning surface of the drum, coverage washed with a perforated sheet, as 2: 1.

Figure 1 shows a General view of the inventive baking powder. The dehumidifying horizontal baking powder for cotton contains a skeleton 1, a working zone 2 located above it, equipped with a pair of feeding cylinders 3 and an outlet channel 4. A knife drum 5 is located in the center of the working zone. An outlet pipe 6 is installed in front of the outlet channel 4. A part of the cleaning surface of the knife drum 5, located opposite the nozzle of the pneumatic suction 6 is covered by a concentrically placed perforated sheet 7 for a wiring of 15-20 mm The length of the arc of the cleaning surface of the drum 5, covered by the grate 8, refers to the length of the arc of the cleaning surface of the drum 5, covered by the perforated sheet 7, as 2: 1. Grate 8 separates the working area from the carbon chamber 9, and the perforated sheet 7 is in contact with the nozzle of the suction pump 6 with the formation of the vacuum chamber 10.

The machine operates as follows. The fibrous material is fed by a pair of feed cylinders 3 under the influence of a knife drum 5. In the clamped state, it is divided into shreds. During the interaction of cotton scraps with the grate 8, large debris is emitted into the carbon monoxide chamber 9. Then, when the pulp moves along the surface of the perforated sheet 7, dust, fluff and small debris penetrate the vacuum chamber 10 and are removed through the nozzle

air suction pump 6 to the filters. The cleaned pulp through the output channel 4 exits and goes to the next machine.

Thus, the proposed machine provides effective cleaning of cotton from both large weed impurities, removing them through the grate to the carbon chamber, and from dust, lint and small weed impurities, removing them through the perforated surface to the filters.

Experience has shown that the use of a dedusting horizontal cultivator for cotton increases the cleaning effect by 15-20%, which leads to a decrease in breakage in spinning by 10-15%.
