Description

Gravity paddle mixer for fibrous materials

The invention includes a machine for manufacturing of mixtures of substances with a fibrous and granular structure. At the same time, it takes over the functions of the buffering and the metered delivery of the mixture · The machine is preferably used in plants for production of mixtures, mainly feed mixes, with proportions of fibrous substances are also used it contributes to the reduction of the technological equipment and to a more rational organization of processes This increases throughput while reducing process costs,

Many technical solutions are known, whereby machines are used for the production of mixtures · Thereby the mixers are operated as continuous or discontinuous Mixer differentiated · In terms of design, they differ in terms of the mixing principle in two groups. While in one group the entire container circulates together with the mixing elements, in the other Group of containers rigidly connected to the frame and the mixing elements are on one or more rotating shafts or fixed on the inside of the stationary container. The mixing elements are known in a wide variety of geometric shapes and arranged so that the goods in a certain direction is promoted.

With all known mixers only pourable Components are mixed, while the mixing quality and energy consumption are in the individual Constructions very different. Whereby the mixers with rotating containers have a smaller one Energy consumption than the mixers with rotating mixing shafts · The mixing quality is with mixers with rotating mixer shafts are usually sufficient, while they are insufficient for mixers with rotating containers is, the shape of the mixing elements also playing an essential role.

The known mixers are unsuitable for fibrous materials with restrictions. Although the pad mixer can be used to mix fibrous materials with slippable and liquid components, a certain buffer effect in the system is not achieved with this construction either. There is also no mixer that dispenses the material in a dosed controlled manner using a reference variable. With all known solutions, the buffering, mixing and metered dispensing of fibrous materials cannot be implemented, so that a high level of plant engineering, a large space requirement and the associated construction costs are required.

The aim of the invention is to develop a machine for the buffering, mixing and dosing of fibrous Serves fabrics. This is intended to be used primarily in the production of animal feed and other mixtures fibrous materials, which reduces the mechanical engineering effort, increases the production capacity, the process costs and the specific energy consumption can be reduced «

The object of the invention is to design a machine from the working principle so that they are used for buffering, mixing and dispensing putters fibrous materials can be used, has a low energy consumption and is not prone to clogging. According to the invention, the task is yellow in that a rotating drum mounted on the end faces is used, on the inside of which mixing elements are attached. The good is on one end The material is fed in via a screw and the goods are also discharged from the other end a worm in connection with a bucket wheel. In the! Drum (also known as the mixing container) there is one in the center Paddle screw arranged, which is used for mixing and return transport «

The machine according to the invention for buffering, mixing and metering fibrous materials is structurally like this designed that in the frame (1) the mixing container, consisting of the throw-in cylinder (2), the intermediate cylinders (3) and the discharge cylinder (4), is mounted «On the front sides of the mixing container are central Bearing rings (9) attached, through which the housing of the discharge screw (14) and the inlet corner (11) pass protrude. The housings (11, 14) are on the frame (1) attached · Mixing elements (5) and discharge elements (6) are installed in the mixing container. The gear motor (7) for driving the mixing container is on the frame (1) attached. The paddle screw (13) is on the housing of the inlet screw (11) and on the housing of the discharge screw (14) stored. On the casing of the discharge chord (14) is an inlet funnel-shaped upwards - *

The machine according to the invention works on the principle of mixing by gravity. Through the in the Attached in the middle of the front sides of the mixing container Bearing rings (9) are the materials to be processed with the help of an inlet screw (10) and a discharge screw (17) infeed and removed · The drive of the Miachbehälters consisting of four cylinders (2,3,3 »4) takes place via the chain drive (8) by the gear motor (7) · The mixing elements (§) take over the puncture of mixing and twisting. Are in the discharge cylinder (4) the discharge elements (6) are arranged in such a way that they feed the material into the hopper of the housing of the discharge screw *

The paddle worm (13) is connected to the inlet worm ( ¹ IO) and is also driven by the gear motor (12). The paddles (15) of the paddle screw (13) are attached in such a way that the mixing process is supported and the material is conveyed back. The baffle plate (16) prevents the discharge cylinder (4) from clogging. The discharge screw (17) is driven by the direct current gear motor (18). The mixing container is evacuated through the aspiration tube (19), which prevents dust from escaping at the sealing points.
