DE2950661A1 - Brick hardening and drying unit - has rotary drum with platforms for bricks operating continuously - Google Patents

Abstract

The rapid hardening and drying equipment is for bricks and concrete components. A rotary drum incorporates platforms for the bricks, being continuously heated or supplied with steam. Temperature and operating speed are adjustable, and insulating material is provided on the inside and outside and at the ends, to reduce heat loss. The hardening and drying operation takes place continuously, during the upwards movement.

Description of the claims for the

Rapid hardening / drying system "

for the brick / clay and concrete / concrete block

Title:

Snow hardness / drying system "

Field of use:

The invention relates to accelerating the hardening / drying process in the production of the brick / clay and concrete / block industry.

Purpose:

In this system, the phases of loading, drying / Hardening as well as cooling and ejection operated. There will be a lot of equipment such as transport trolleys with rail systems as well as space, space and time saved.

The curing / drying capacity is increased significantly. The cost of this Process are significantly reduced. This machinery can be incorporated into any existing brick / clay and concrete / block industry operation will.

State of the art:

To accomplish this task one uses in the relevant brick / Concrete block industry simple tubular autoclave or similar! Heating systems. The tiles or tiles are on boards or Steel sheets pushed into the system and heated. Then taken out again and transported to be burned. Or waiting in the concrete block industry it takes 10 to 15 hours in large drying halls with huge stacking shelves for the products to harden / dry out from the normal room air. In the winter the latter is usually only possible by heating the halls.

State of the art criticism:

Drying times / curing times are too long. Long transport routes from the manufacturing machine to the conventional heating systems. Production cycle and hardness / drying times are not identical. You need temporary storage. All this implies that one huge warehouses need rail systems with Dolly. After all, you need too many staff for this process. The result of this NOW state is that this production phase is too expensive.

Task:

The invention is based on the problem of the enormous transport routes to dismantle from the various manufacturing machines for intermediate storage for the purpose of drying / hardening, to save storage space, energy and time and Finally, adapt the drying and curing times to the production rhythm.

Solution:

( Reproduction of the characterizing part of claim 1)

This object was achieved according to the invention in that the rapid hardening / drying system " pushes the products onto the platform of the rotating drum immediately behind the manufacturing machine on boards / sheets and immediately afterwards by turning the rotating drum piece by piece into the heating or steaming zone and after about 300 ° of the circular path comes into the cooling zone.This ensures that the curing / drying time (depending on the product) can be adjusted to the production rhythm.

Further embodiment of the invention

(Reproduction of the characterizing part of a sub-claim)

Due to the fact that the products "rise" immediately behind the production machine, namely in a circular path (depending on If required, it can also be elliptical, polygonal, rectangular, square or continuously in different planes). Essential is just that the drying / hardening is not carried out on the surface, but one goes up with this process!

Achievable benefits:

The advantages achieved with this invention are that this machine, which can be set up in a very small space, saves space, area, transport routes and the necessary means of transport, as well as energy and time. In the brick industry, the products may run into the combustion chambers immediately after discharge aui i "m" SIIiLLIV "- as in the clay industry. In the concrete / concrete block industry, after being ejected from the "SPEEDY", the products can be packaged (usually shrink-wrapped in foil or braced with steel strip) and transported to the customer.

Description of one or more exemplary embodiments:

An exemplary embodiment is shown in the drawing. The top view of the "SPEEDY" shows, for example, the direction of insertion of the finished products (interlocking plaster, Pavement slabs, kerbstones etc.) of the concrete / concrete block industry. Depending on the length of the rotating drum, a layer of products on boards /

Sheets pushed onto the platform below. With that thrust the cured / dried layer is simultaneously pressed from the same platform in the ejection direction. The rotating drum then moves continue to the next platform and the process described is repeated.

Depending on the operation, the heating on the inside of the outer thermal insulation jacket (core filled with non-combustible mineral fiber) is carried out with infrared light or a similar heating medium, primarily with the Brick / clay industry, because it is about quick drying and removal of the water from the product.

In the concrete / concrete block industry, heating is carried out with steam because the concrete product is exposed to water during the setting / hardening phase may not be withdrawn under any circumstances.

These two heating systems distinguish the two basic types. Other distinguishing features are the length and diameter the machinery and forms - as shown under the point "Further embodiment of the invention". The two basic types (steam heating or dry heat) are used depending on the company, whether it is the concrete / concrete block industry or the brick / clay industry.

Shapes like length and diameter, elliptical, polygonal etc. are basic facts for the service SEfff. "! Also the existing company buildings are decisive for the form d * s "# Ρβ8β ¥". For example, a flat Operations hall never or normally not a circular "SPEEDY" mounted, but an adapted shape. However, always geared towards the "achievable benefits"
