Description

(54) BELT-RING PRESS

one

The invention relates to equipment for pressing, in particular, to the design of belt-ring presses.

Known belt-ring press containing mounted in the frame pressure supports, placed on the pressure supports rigid ring with sides and filter plates mounted on its surface, as well as an infinite flexible filter belt and a toothed plate chain, coupled with a rigid ring using pressure supports, at the same time, holes 1 are made on the rim of the rigid ring between the filtering plates.

However, in a known belt-ring press, insufficient mechanical dewatering and capillary-porous materials are produced.

The purpose of the invention is to intensify the process of mechanical dewatering of capillary-porous materials by restoring their structure and intermediate regeneration of filter plates.

The goal is achieved by the fact that the well-known belt-ring press containing mounted in the frame pressure supports, placed on the pressure supports

a rigid ring with sides and filter plates fixed on its outer surface, as well as an endless flexible filter belt and a toothed plate chain articulated with a rigid ring using pressure supports, while radial holes are made on the rim of the rigid ring between the filter plates with a loosening unit installed on the outer side of the rigid ring at its sides, and a steam distributor, mounted on the inner side of the rigid ring opposite the loosening unit in the area of ERSTU, wherein the loosening unit is configured as a housing mounted therein rotatably agitator, the latter is made in the form of keta pa15 toothed disks conjugated with filter plastiiami and drum covered by an endless filter belt and a toothed plate chain.

The belt-ring press is also provided with air distributors installed on the inner side of the rigid ring behind the steam distributor in the direction of rotation of the rigid ring.

FIG. 1 shows a belt-ring press, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - rigid ring with a steam distributor and air distributors placed on its inner side.

A belt-ring press consists of 1 pressure supports 2 mounted in a frame, placed on pressure supports 2 of a rigid ring 3 with flanges 4, filtering plates 5 fixed on the outer surface of a rigid ring 3, an endless flexible filtering belt 6 and a toothed lamellar chain 7 articulated with rigid ring 3 using pressure supports 2, loosening unit 8, installed on the outer side of rigid ring 3 at its sides 4, steam distributor 9, installed on the inner side of rigid ring 3 opposite the loosening unit 8, and air distributors 10 installed on the inner side of the rigid ring 3 behind the steam distributor 9 in the direction of rotation of the rigid ring 3.

The loosening unit 8 is made in the form of a body 11 mounted thereto for rotation of the ripper 12 and the drum 13, covered by an endless filtering belt 6 and a toothed lamellar chain 7.

The ripper 12 is made in the form of a package of toothed disks 14 mated with filter plates 5. The rim of the rigid ring 3 between the filter plates 5 has radial holes 15, in the placement area of which are steam distributors 9 and air distributors 10. The electric motor 16 connects a rigid 17 through differential 17 the ring 3 and the toothed plate chain 7. The knot 8 is loosely located in the middle of the compression arc of the material.

The press works as follows. The electric motor 16, through the differential 17, drives the rigid ring 3 and the toothed plate chain 7. The pressure supports 2 press in on the toothed plate chain 7 and the endless flexible filter belt 6. As a result of the friction between them, the latter is set in motion.

The loading device 18 continuously supplies specially prepared low-decomposition peat moss. The dewatering process is divided into two stages: I stage - from loading to loosening and AND - from loosening to unloading. By applying a pressing pressure under the first pressure supports 2, the material begins to densify, and primarily at the surface of the endless flexible filtering belt 6 and the filter plates 5. In this case, the moisture is mainly pressed out of the layers adjacent to the filtering surface.

With the removal of moisture, the capillary-porous structure of these layers is disturbed, and the moisture contained in the middle part is almost not removed. Water drainage from the central layers is difficult.

Dehydrated in the first stage, the material enters the node 8 loosening. The ripper 12 rotates in the direction of the movement of the rigid ring 3 and at the same time touches and cleans the surface of the filter plates 5. The gear disks 14 destroy and mix the incoming compressed layer of dehydrated material. From the distributor 9, through the radial holes 15, the steam enters the moisture removal channels 19, and from there into the loosening unit 8

 through the filtering structure of the filter plates 15. The steam, under excessive pressure, passes through them, cleans their filtering surface and restores their performance. In unit 8, loosening the steam, condensing, heats the material.

The heated material in the loosened state, captured by the endless flexible filtering tape 6 and the rigid ring 3, enters the second stage of dehydration. The pressure developed by the pressure supports 2 increases from the support to the support as the material moves and reaches a maximum value under the last pressure support 2. Moisture, pressed out of the material, is removed through the filter plates 5 and enters the drainage channels 19. Compressed air, supplied to the air distributors 10 through the radial holes 15, under pressure gets into the drainage channels 19 and draws moisture through the end holes in the sides of the rigid ring 3. The pressed material is discharged by the discharge arrangement Property 20.

Introduction to the process of dewatering of the interstitial loosening of the material and heating it makes it possible to intensify the process of squeezing moisture out of capillary-porous materials.

The use of air distributors and the implementation of a purge of moisture

5 channels reduces the leakage of wrung moisture into the material while reducing the pressure between the compression onors.

The technical and economic effect from the introduction of: the invention is achieved due to the intensification of the process of mechanical dewatering of capillary-porous materials in comparison with the basic object.
