(54) УСТРОЙСТВО ДЛЯ УДАЛЕНИЯ КРУПНЫХ ЗАГРЯЗНЕНИЙ ИЗ СТОЧНЫХ ВОД(54) DEVICE FOR REMOVAL OF MAJOR POLLUTION FROM SEWAGE WATER

II

Изобретение относитс к области механической очистки сточных вод, а именно, к устройствам дл задержани из сточных вод наиболее крупных загр знений.The invention relates to the field of mechanical treatment of wastewater, in particular, to devices for the retention of the largest contaminants from wastewater.

Известно устройство дл удалени крупных загр знений из сточных вод, содержащее транспортер с фильтруюпдим полотном и ведущими ведомыми роликами, валами и приводом 1.A device for removing large-scale contaminants from sewage is known, which contains a conveyor with a filtering web and leading driven rollers, shafts and a drive 1.

Однако, известное устройство сложно по конструкции и в эксплуатации из-за возможности заклинивани загр знений между звень ми полотна.However, the known device is complicated in design and operation due to the possibility of seizing contaminations between the links of the web.

Цель изобретени - повышение эффективности использовани за счет обеспечени удалени загр знений с фильтрующего полотна.The purpose of the invention is to increase the efficiency of use by ensuring the removal of contaminants from the filter sheet.

Указанна цель достигаетс тем, что вал ведущих роликов и один вал ведомых роликов располагаютс в верхней части устройства , а другой вал ведомых роликов располагаетс в нижней части устройства, при этом рассто ние между ведущими роликами больше рассто ни между ведомыми, а фильтрующее полотно выполнено из отдельных звеньев и снабжено приспоссбление:,; it о очистки.This goal is achieved in that the shaft of the drive rollers and one shaft of the driven rollers are located in the upper part of the device, and the other shaft of the driven rollers is located in the lower part of the device, while the distance between the driving rollers is greater than the distance between the driven rollers and the filter sheet is made links and equipped with:,; it's about cleaning.

Кроме того, приспособление дли очистки выполнено из смонтированного над фильтрующим полотном стержн , расположенного горизонтально и перпендикул рно направлению движени с прикрепленными к нему наклонными стержн ми, расположенными между звень ми фильтрующего полотна.In addition, the cleaning device is made of a rod mounted above the filter sheet, located horizontally and perpendicularly to the direction of movement with inclined rods attached to it located between the links of the filter sheet.

На фиг. 1 изображено устройство, продольный разрез; на фиг. 2 - вид устройства в плане.FIG. 1 shows a device, a longitudinal section; in fig. 2 is a plan view of the device.

Устройство включает фильтрующее полотно , состо щее из отдельных звеньев 1, The device includes a filter sheet consisting of individual links 1,

10 ведущего 2 и ведомых 3 и 4 валов, на которых жестко закреплены ролики 5. Зона между валами 3 и 4 вл етс рабочей, рассто ние между звень ми фильтрующего полотна в этой зоне посто нно и определ етс расчетом.10 leading 2 and driven 3 and 4 shafts, on which the rollers 5 are rigidly fixed. The area between shafts 3 and 4 is working, the distance between the parts of the filter sheet in this area is constant and is determined by calculation.

Claims

The space between shafts 4 and 2 serves to clean the grid from contamination and the distance between links here increases. A conveyor belt 6 is provided for removal of contaminants, and inclined rods 7, which are attached to burners, are mounted on the filter sheet to remove contaminants stuck to the links of contaminants. The device operates as follows. The wastewater to be cleaned passes through the distances between the moving links 1 of the filter sheet. Large soils are trapped and rise from the work area to the cleaning zone. In the cleaning zone, the delayed charges, due to the increase in the distance between the links, fall down and fall onto the conveyor 6. The rods 7 clear the links from sticking soils. The device of the grating in the form of a moving filtering sheet consisting of separate links simplifies its design, facilitates maintenance due to the easy access to the individual elements of the device, makes cleaning the grid from contamination simple and effective. Claim 1. Device for removing large contaminants from wastewater, comprising a conveyor belt with filtering web, driving and driven rollers, shafts and a DRIVER, characterized in that, in order to increase the efficiency of use by ensuring the removal of impurities from the filtering web, the shaft the leading rollers and one shaft of the driven rollers are located in the upper part of the device, and the other shaft of the driven rollers is located in the lower part of the device, while the distance between the leading rollers is greater than the distance between home rollers, and the filter sheet is made of separate links and is equipped with a device for cleaning it.

2. The device according to claim 1, wherein the cleaning device is made of a rod mounted above the filter sheet that is arranged horizontally and perpendicular to the direction of movement with inclined rods attached between it and the links of the filter sheet.
