(54 ) ШНЕКОВЬЙ ПРЕСС ДЛЯ ОБЕЗВОЖИВАНР1Я ШЛАМА И ЖИДКОГО(54) AUGER PRESS FOR DRAIN AND LIQUID DECOMPOSITION

НАВОЗА .Manure.

II

Изобретение относитс к машиностроению и может быть использовано при удалении жидкости из влагосЬдержащих материалов, например из птака или жидкого навоза.The invention relates to mechanical engineering and can be used when removing liquid from moisture-holding materials, for example, from ptaka or liquid manure.

Известен шнековый пресс обезвоживани шлама и зкидкого навоза, содержащий камеру прессовани в виде перфорированного цилиндра и охватывающего последний кожуха, размещенный в цилиндре прессующий шнек, и запорный конус С The known screw press for dewatering sludge and manure, containing a pressing chamber in the form of a perforated cylinder and covering the last casing, a pressing auger placed in a cylinder, and a stop cone C

Недостатками такого пресса вл ютт с значителен уровень щума и невысокое качество отжимаемой жидкости (фильтрата).The disadvantages of such a press are a significant level of shchum and a low quality of pressed liquid (filtrate).

Цель изобретени - повьшение качества фильтрата и звукоизол ции пресса.The purpose of the invention is to improve the quality of filtrate and sound insulation of the press.

Указанна цель достигаетс тем, что шнековый пресс дл обезвоживани шлама и.жидкого навоза, содержащий камеру прессовани в виде перфорированного барабана и охватьгоающего последний кожуха, размещенный в. барабане прессующий шнек и запорный конус, снабжен, дном, выполненным в виде перфорированного кольца и размещенным между кожухом и перфорированным барабаном, а пространство между перфорированным барабаном, дном и кожухом заполнено гравием.This goal is achieved by the fact that a screw press for sludge dewatering and liquid manure contains a press chamber in the form of a perforated drum and cover the last casing placed in the. drum pressing screw and locking cone, provided with a bottom, made in the form of a perforated ring and placed between the casing and perforated drum, and the space between the perforated drum, bottom and casing filled with gravel.

На фиг. 1 изображен шнековый пресс; на фиг. 2 - за.порный конус.FIG. 1 shows a screw press; in fig. 2 - back cone.

Пресс содержит электропривод 1, питающий патрубок 2, съемную крьшгку 3, камеру 4 прессовани в виде перфорированного барабана 5 и кожуха 6, шнек 7 с переменным шагом, конусообразный стакан 8с винтовыми ребрами 9 и каналами 10, неподвижный шток 11, вл ющийс одновременно нижней опорой вала шнека, патрубок 12 дл отвода фильтра, перфорированное The press contains an electric drive 1, a power supply nozzle 2, a removable bolt 3, a pressing chamber 4 in the form of a perforated drum 5 and a casing 6, a screw 7 with variable pitch, a tapered cup 8 with helical ribs 9 and channels 10, a fixed rod 11, which is simultaneously a lower support screw shaft, pipe 12 for removal of the filter, perforated

20 дно 13, установленное наклонно, и наполнитель 14. В качестве наполнител может быть прин т гравий.20, a bottom 13, which is set obliquely, and a filler 14. Gravel may be taken as a filler.

Claims

The press works as follows. E: 1 spectro drive 1 drives the screw 7 to rotate. Moisture-containing material, non-example sludge or manure, is fed into the pressing chamber 4 through a feed nozzle

2. Inside chamber 4, the source material fills the interturn space of the screw. The filtrate is removed through the perforated drum walls due to the pressure difference inside the drum and into the space between the outer surface of the drum 5 and the casing 6. The dense phase of the material is captured by the turns of the screw and feeds into the pressing chamber 4, gradually compacted by decreasing interturning volumes of the screw . In the lower part of the pressing chamber, the filtrate is finally released. The required degree of moisture of the compressible material is achieved by controlling the cross section of the channels 10 formed by the ribs 9 by displacing the cone-shaped glass in the axis of the fixed rod 11, the Glass 8 also serves to completely close the pressing chamber for the press entry period in normal operation. The filtrate, entering the space between the drum 5 and the casing 6, filled with filler, is additionally filtered and flows through the perforated 2 inclined bottom into the nozzle 12. The presence of the filler allows to obtain a more purified filtrate, reduce the emission and reduce noise during press operation, which will improve working conditions of staff. An inventive screw press for dewatering sludge and slurry containing a compression chamber in the form of a perforated drum and covering the last casing, a pressing auger placed in the drum and a shut-off cone, characterized in that, in order to improve the quality of the filtrate and sound insulation, it has a bottom, filled in the form of a perforated ring and placed between the casing and the perforated drum, and the space between the perforated drum, the bottom and the casing is filled with gravel.
