(54) КОЛОСНИКОВАЯ РЕШЕТКА ОЧИСТИТЕЛЯ ВОЛОКНИСТОГО МАТЕРИАЛА(54) KOLOSNIKOVAYA GRID OF CLEANER FOR FIBER MATERIAL

Изобретение относитс к текстильной промышленности и может быть использовано дл очистки волокнистого материала, .,This invention relates to the textile industry and can be used to clean a fibrous material,.,

По основному авт. св. №.619553 известна колосникова решетка, каждый колосник которой представл ет собой волнообразно изогну1ый пруток 1.According to the main author. St. No. 619553 is a famous grate, each grate of which is a wave-like curved bar 1.

Волнообразный.изгиб колосников предопредел ет выделение сора преимущественно удлиненной формы (черешки , стебли растений и т.д.), однако в хлопке-сырце соде.ржитс значительное количество и мелких сорных примесей размером менее 8 мм, поэтому по вл етс .необходимость (при сохранении эффективности выделени сора удлиненной формы) интенсифицировать процесс выделени и мелкого сор.а,The undulating curve of the grate predates the release of litter, which is predominantly elongated (petioles, plant stems, etc.), however, in cotton raw there is a significant amount of small weed impurities less than 8 mm in size, so it appears that preservation of the effectiveness of the elongated form of litter) to intensify the process of excretion and fine litter,

Недостатком известной решетки вл етс невысокий очистительный эффект по . мелкому сору.A disadvantage of the known grate is the low cleaning effect of. small litter.

.Цель изобретени - повыгиение очистительного эффекта. .Указанна цель достигаетс тем, что в колосниковой решетке очистител волокнистого материала, содержащей закрепленные с определенным шагом на раме колосники, представл ющие собой волнообразно изогнутые . прутки, каждый пруток решетки дополнительно изогнут по волновой линии, амплитуда и длина волны которой меньше соответствующих параметров основного изгиба прутка.The purpose of the invention is to increase the cleansing effect. The above purpose is achieved by the fact that in the grate the cleaner of fibrous material contains grates fixed with a certain step on the frame, which are wavy and curved. rods, each lattice rod is additionally bent along the wave line, the amplitude and wavelength of which is less than the corresponding parameters of the main bend of the rod.

Соотношение каждого из указанных параметров .составл ет 1/2-1/3,The ratio of each of these parameters is 1 / 2-1 / 3,

На чертеже изображена предлагаема колосникова решетка.The drawing shows the proposed grate.

Решетка включает раму, образованную двум боковинами 1, соединенными распорками (на чертеже не указаны), The grille includes a frame formed by two side walls 1 connected by spacers (not shown in the drawing),

15 колосники 2 в виде прутков круглого сечени , установленных в плоскости : решетки между боковинами и изогнутых по основной и дополнительной волнам.15 grate bars in the form of round bars installed in the plane: grates between the sides and bent along the main and additional waves.

Волокнистый материал перемещаетс Fibrous material moves

20 по решетке ..и очищаетс :от.сорных примесей . Дополнительный изгиб прутков за счет увеличени живого сечени решетки и количества ударных взаимодействий материала с выступами прут25 ков позвол ет интенсифицировать процесс выделени мелкого сора, не снижа вывод щей способности решетки по сору удлиненной формы. Соотношение указанных параметров (1/2-1/3) 20 through the grid .. and cleaned: from impurities. The additional bending of the rods by increasing the living cross section of the lattice and the number of impact interactions of the material with the protrusions of the rods allows to intensify the process of shallow litter release without reducing the output capacity of the lattice along the elongated litter. The ratio of these parameters (1 / 2-1 / 3)

Claims

30 of the main and additional waves is optimal, since a decrease in it leads to the bottom of the grid, and an increase reduces the cleaning effect. It is known that the main mass of particles of small litter has sizes up to 4-5 mm. In accordance with the value of weed impurities, a further increase in the bending of the grate does not bring effect. This occurs because the increase in the number of waves of the bent three times and. more along the main wave of the PR.IVODIT leads to a decrease in the free space in the bends of each Ch wave, which reduces the release into the weed chamber of small trash, which are later incorporated into the pulp, turning into an active trash. The additional bending of the main wave leads to an increase in the living cross section, as can be seen in the attached drawing. An increase in the live cross section and the number of percussion interactions of cotton with the grate leads to an intensification of the process of separating small weed impurities, which increases the cleaning effect by an average of 6%. Claim 1. Grid cleaner for fibrous material according to author. EV, I 619553, characterized in that, in order to increase the cleaning effect, each bar of the lattice is additionally bent along the wave line, the amplitude and wavelength of which MeHbiue correspond to the corresponding parameters of the main bend of the rod.

2. Lattice according to claim 1, characterized in that the ratio of each of these parameters is 1 / 2-1 / 3. Sources of information taken into account during the examination 1. USSR author's certificate No. 619553, cl. About 01 G 9/14, 1976.
