Description

FIELD OF TECHNOLOGY

The utility model relates to construction equipment, namely to gravity-type mixers and is intended for the preparation of concrete and other mixtures.

BACKGROUND

Known mixing drum containing at least one blade with a mount for attaching the blade to the drum inside it, so that when using the blade rotates with the drum and helps to mix its contents, and the mounting device is removable, which allows you to remove the blade from the drum for cleaning and subsequently install it again for use (GB2453543, 04/15/2009, IPC B01F9 / 02).

A mixer is also known, comprising a mixing drum connected to a rotation drive and rotatably mounted on a support, which comprises a shaft with a blade fixed thereon for mixing the mixture and cleaning the inner surface of the drum, the shaft being fixed by means of movable joints on the drum handle with the possibility of regulation the gap between the blade and the inner surface of the drum (RU 174802, publ. 02.11.2017, IPC B28C 5/24).

A portable mixer is also known, comprising a drum with a lever, a stand and a mixing device at least partially inside the housing, in which the stand supports the drum and the drum is detached from the stand, the mixing device comprises an engine and a drive wheel in which the engine is located inside the housing, and the drive wheel extends from the housing to connect to the drum. The case is waterproof. In use, the drive wheel comes into contact with the drum and causes it to rotate. The drum may contain fixed blades. The motor can be powered by mains or battery. The drum may further comprise a lid (GB2555382, 05/02/2018., IPC B01F9 / 00).

ESSENCE OF A USEFUL MODEL

The technical problem solved by the claimed utility model is to create a new mixer for industrial mixtures having a simpler design, more convenient to operate.

The technical result achieved when using the utility model is that the design of the mixer facilitates cleaning of the mixer after use, and also allows for better loading and unloading of components of industrial mixtures with a reduction in material loss and dust emission during operation.

To solve the problem and achieve the claimed technical result, a mixer is proposed comprising a mixing drum made in the form of a housing with a cover mounted on a rotary support and rotatably supported, characterized in that the drum housing is made in the form of a container with a smooth inner surface, the top of the drum has a lid mounted for fixation on the drum casing, while the lid is equipped with blades fixed to it and a filling funnel, when ohms on the inner surface of the lid around the entire periphery sealing ring.

In addition, in the proposed mixer, the lid can be fixed on the drum body by means of ring locks.

Moreover, in the proposed mixer, the lid can be equipped on the outside with hinges for attaching a filling device.

DESCRIPTION OF IMPLEMENTATION OF A USEFUL MODEL

As shown in FIG. 1, the mixer comprises a mixing drum 3 connected to a rotation drive 1 and rotatably mounted on a support 2.

In turn, the mixing drum 3 has a hollow body 4 and does not have any elements inside, while mixing the mixture in the drum is carried out by the blades 5, which are placed on the inner side of the cover 6, which in turn is fixed on the mixing drum 3.

The lid 6 is fixed to the mixing drum 3 by means of fasteners 7, for example, coupling bolts. But as shown in FIG. 3, the fixation can be carried out with cap locks 8. However, these types of fixation are not the only ones and can be carried out by other possible options.

The cover 6 has a filling funnel 9 in the central part with inclined walls protruding beyond the contours of the cover. This filling funnel 9 serves to fill the components of the industrial mixture, while in the preferred embodiment, the filling funnel 9 is located in the center of the lid 6, but can be shifted depending on the shape and configuration of the drum 3, while this arrangement of the filling funnel 9 does not allow the mixture to splash out even at high mixing speeds. And the size of the filling funnel 9 is preferably selected in accordance with the size of the filling device 10, which provides a hermetic supply of components of the industrial mixture from the dispenser, and which can be connected to the filling funnel 9.

For this, as shown in FIG. 4, loops 11 may be provided on the upper side of the cover 6 for attaching the filling device 10 to the filling funnel 9. Thus, the components of the industrial mixture can be loaded both mechanically and automatically, which makes it possible to use a mixer of this type, as in an open construction site so in the production room.

As shown in FIG. 5, when the components of the industrial mixture are hermetically supplied, the skirt 13 of the filling device 10 is secured with ring locks 8 mounted on the skirt 13 for loops 11, and the corrugated sleeve 14, weighted at its end, is lowered by cables 15 below the level of the cover 6 directly into the filling funnel 9. When this skirt 13 has a rigid base with a sealing element 12 around its perimeter.

As shown in FIG. 6 after the hermetic supply of the components of the industrial mixture is carried out, the sleeve 14 rises with cables 15 from the filling funnel 9 above the level of the cover 6.

In the hermetic supply of components of the industrial mixture in accordance with FIG. 5 and FIG. 6, when the sleeve 14 of the filling device 10 is raised above the level of the cover 6, the pressure inside the drum 3 decreases, which is formed due to a decrease in the air volume inside the drum 3 when the components of the industrial mixture are supplied, which in turn leads to a reduction in dust emission.

As shown in FIG. 2, in addition to the fasteners 7, the filling funnel 9, the blades 5, and the loops 11, the cover 6 around the entire inner perimeter has a sealing element 12, as well as the skirt 13 of the filling device 10, which in turn provides a more tight fixation of the cover 6 on the mixing drum 3, providing additional reliability to prevent splashing of the mixture with active stirring.

Thus, the claimed utility model has several advantages, namely:

a) it allows to reduce production costs by reducing losses during unloading of the finished mixture from the mixer, which is ensured by the design of the drum, namely due to the absence of any elements inside which delay a certain amount of the mixture during unloading, which allows for better and faster cleaning mixer after operation;

b) due to the ability to fix the filling device on the lid of the mixer, losses during loading of the mixture components are reduced, and dust emission is also reduced, which reduces the operator’s health and environmental load.
