SU713577A1 - Apparatus for removing filtered viscous sediments off drum-type suction filter - Google Patents

Description

The invention relates to devices for removing filtered viscous sediments from a drum vacuum filter and can be used in the medical and other industries to remove viscous sediments, such as sediment mycelium of antibiotics and similar products.

A device is known for removing a filtered sludge from a vacuum filter comprising a housing-trough with a sludge slice mechanism, an auger for moving sludge located in a trough-housing, and its drive 1.

This device is used to remove loose sediments having a crystalline structure, and becomes inoperable at distance, and precipitates with viscous properties, as sediment sticks to the screw between the turns, the sediment rotates with the screw, and the grinding of the precipitate by screw turns, resulting in sediment transportation to the discharge opening stops

In order to ensure the possibility of transporting such a sediment, it is necessary to dilute the water in a 1: 2 ratio. However, the sediment diluted with water is economically unsuitable for subsequent use, such as drying or destruction by incineration.

Nowadays, in medical plants, sludge is dumped into dumps. suburban green zone, which leads to the death of the flora and contamination of the environment with toxic substances forming 1 1 s during the decomposition of the sediment.

However, in the TsAOM device, the removal efficiency of viscous sediments is low.

The purpose of the invention is to increase efficiency} €: efficiency of increasing viscous debris

by preventing their crushing moisture,

This is achieved by the fact that the transporting means is made in the form of straight lines, 1x1, located one above the other in a closed loop with the sludge slice mechanism placed on it.

It is advisable to cut the sediment mechanism in the form of a trolley with a scraper, to install; a plastic with the possibility of reciprocating and displacement, and to equip the guides with hingedly mounted arrows with springs

FIG. 1 shows a device for removing sediment; general view; FIG. 2 is a view along arrow A in FIG. in fig. 3 shows a section BB in FIG. 2; in FIG. 4, node 1 in FIG. 1; in fig. 5 - node II in FIG. 1,

A device for removing sediment consists of guides 1, 2, mounted in a closed circuit one above the other, on which there is a carriage 3 with front wheels 4, rear wheels 5 and with a scraper b, drive 7 with stepless speed control of the movement of the carriage with scraper, systems blocks 8, a rope 9 wound on a drum 10. Guides with a trolley with a scraper and blocks are mounted on a bearing I-11, which is mounted on existing trough brackets 12 of a drum vacuum filter 13,

To ensure that the trolley movement on both sides of the upper guide 1 is reversible: the forward stroke arrow 14 and the reverse arrow 15. The forward arrow is held in an inclined position by the spring 16, the reverse arrow is kept in the horizontal position by the spring 17. Both springs are tared by weight of trolley 3,

At the extreme points of the lower rail 2, limit switches 18 are installed.

The device works as follows.

Using a rope 9 wound on the drive drum 10, through the system of blocks 8 under the influence of the drive 7. The cart 3 with the scraper b moves reversely along the closed contour of the guides 1, 2. The viscous sediment cut off from the vacuum drum filter 12, during the working stroke of the trolley, it is grasped by the scraper and is moved by it to the discharge opening in the trough bracket. When the working stroke of body 3, moving along the lower guide 2, raises the arrow straight

course 14, passes under it, after which the arrow is lowered under the action of the spring 16. After unloading the sludge car, moving along the guides, one of its front wheels 4 presses the lever of the limit switch 18, the driving drum 10 begins to rotate in the opposite direction and the carriage moves in its motion to idle Q (reverse) stroke. When idling, the cart with the scraper rises along the arrow of the forward stroke 14 and passes along the upper guide 1, so that the scraper 6 does not touch the draft, again

accumulating in the bath 12.

At the end point of the drum, the carriage 3 is lowered along the reversing arrow 15 from the upper guide to the lower one. After the cart collapses, the shooter returns to its original horizontal position under the action of the spring 17. At this time, the cart one of its rear wheels 5 presses the lever of the limit switch 18, the direction of rotation of the drive drum 10 changes again, and the cart moves into its movement . The cycle of operation of the device is repeated.
