DE2947706A1 - Mixer for building or sealing materials - where stirrer blades are only coupled to driving motor when mixer lid is closed - Google Patents

Abstract

Mixer contains a separate stirrer cage, and is closed by a lid on which a stirrer motor is mounted. When the lid is closed, mechanical coupling is made between the drive shaft of the motor and the stirrer cage; and this coupling is automatically disconnected when the lid is opened. Mixer lid is pref. provided with a seal so that a pressure cooker effect is achieved when hot mixing techniques are employed. Advantages include easy loading and unloading of the mixer; rapid heating times during hot mixing; and worker safety is increased because the stirrer cage stops automatically when the lid is opened.

Description

PATENT DESCRIPTION for the patent application dated October 1, 1979 Title: DECKELRÜ? FRWERK with separate RL-; TWRKAFIG application 5 area The agitator is particularly suitable for use in the construction industry for mixing and stirring mortar, plaster and stucco compounds, as well as sealing material.

Furthermore, the agitator is particularly suitable for batter, din must be heated during the stirring process.

(e.g. plastics or mud and mud masses.) S t a n d der T e c h n i k: It is known that agitators have always been a fixed assembly unit form, i.e. the drive shaft and impeller are mechanically firmly connected to each other In one case, it is driven by a ville in the bottom of the boiler, in the other case a hood-like attachment is attached to the boiler. from which the or the The agitator blades stick out at the bottom. In a third version the agitator is like an outboard motor worked and is also mounted on the edge of the boiler. There is another version in which the kettle is rotated and the gravity of the inside Mass is exploited. (e.g. concrete mixer) X r i t i k des 5 t a n d e 5 der T e c h n 1 k None of the systems listed above are particularly suitable for smaller stirring quantities that are to be processed directly from the stirred tank. This is particularly useful for putties that have to be melted and heated. The constructions are all quite complex and not always easy to use.

A u f E; a b e The invention is based on the object of filling and to facilitate the removal of the batter. The heating times for enamel masses to shorten it considerably, as well as to considerably reduce the risk of injury and accident. Not it is irrelevant that the cleaning process is simplified.

Solution: The object is achieved according to the invention in that the agitator hinged with its mounting plate designed as a cover, by means of a flat band metal clamp is attached to the boiler. This type of attachment is always possible subsequent days. A short, axially resilient protrudes from the inside of the cover Bearing drive shaft stub with clutch plate out. The lid features in its support edge over a heat-resistant seal and can by means of a so-called box cover lock are tightly closed.

As a result, the heating-up time is now reduced in the case of batter to be heated considerably shortened by the pressure cooker effect.

To secure it is a pressure relief valve and a thermometer in the Screwed in cover.

The stirring cage is placed in the kettle and through to the side sheet two spacer rings running around the side in a central one for the patent description bXmg dated ol.lo.1979 Location held.

The lower small stub axle of the impeller runs in a heat-resistant one and maintenance-free plastic bushing. This plastic socket sits in the middle on a flat steel that bisects the bottom of the kettle and that has the lower position ring fixed. The upper stub axle of the impeller is on the held the same type and carries on its, the lid trimmed side as well a clutch plate.

When the cover is closed, the two clutch disks interlock and the agitator can be switched on. To remove the batter is now the lid opens and exposes the entire boiler opening, which is only in the Li never the circle diameter is halved by the narrow flat steel. By The agitator paddle with its upper and lower cross member can then apply slight pressure be brought into a congruent position to the bisecting flat steel strip it is possible to take the agitation from the entire boiler room.

Possibly failing electrical protective contact fuses can through Unintentional starting of the agitator motor will not cause any damage, as only the small clutch plate would be driven. This risk would be equated starting a drill without a drill.

E r z i e l b a r e d o r t e i 1 e: 1. The filling and above all The removal of things is made easier.

2. In the case of enamel masses, the heating-up time is significantly reduced. (Pressure cooker effect ) 3. The boiler and agitator cleaning is made easier.

4. The subsequent attachment is for all boiler types without large Additional effort and costs are possible.

5. DS risk of accidents is considerably reduced.
