Description

The technical field to which the utility model relates.

The utility model relates to the processing of grain products and the production of animal feed.

State of the art

A known line of production of extruded products containing a preparatory section, including a hopper for raw materials, crushers, a mixer, a cyclone precipitator and a collector, an extrusion section including accumulators, a press extruder and an extractor, a grinder preparation section including a crusher, a cyclone precipitator and a hopper drive, auxiliary materials, granulation and packaging and packaging, including storage hopper and bag-loading complex (see patent RU 2443130, IPC: A23P 1/00, published on 02.27.2012).

The mentioned line provides a full range of raw materials processing, including automatic packaging of the finished product, while it refers to stationary production complexes of high power, which require large volumes of raw materials stored near the complex.

However, at present there is a problem of grain processing, which began to churn (burn), for example, due to high atmospheric humidity or because the grain was not properly dried before filling in storage. It is impossible to transport such raw materials over a long distance to a stationary complex, while the time it takes to “save” it takes days or even hours. Often the producer has to throw away the ripened crop.

One way to solve this problem is to create mobile complexes for extrusion processing of grain, which can be delivered directly to the storage location of raw materials.

A well-known mini-plant for the production of animal feed, including a production line mounted on a metal platform transported by rail (see patent RU 1604, IPC: A23N 17/00, publ. 16.02.96). The disadvantages of this solution include limited use, due to the use of rail vehicles to move the line.

A mobile device is known that contains a wheeled transport platform on which a container-type wagon is installed with equipment placed in it (see patent EP 0752464, IPC: C11B 1/00, publ. 05.07.95). However, the mentioned equipment is intended to produce oil from sunflower grain and cannot be used to obtain an extruded product.

As the closest analogue in the presence of signs similar to the essential features of the claimed technical solution, a mobile installation was adopted, which provides for the processing of grain and obtaining an extruded product in the "field conditions", disclosed in the patent CN 101264670 IPC: B30B 11/22, publ. September 17, 2008. The aforementioned installation comprises a wheeled vehicle with a platform on which the vehicles connected in the technological sequence are installed: a feed hopper, an extruder, a strand product storage cooler, a grinding device and means for unloading the finished product.

A significant drawback of the closest analogue is the ability to use the installation only in the warm season, since all the equipment is installed on an open platform. If the equipment is placed in a closed space, a substantial modernization of the installation will be required to ensure acceptable working conditions for the equipment and personnel and the necessary ventilation, as the extrusion process is accompanied by high temperature and high vaporization.

Another significant drawback of the closest analogue is the low maneuverability of the used tractor platform, the large transport dimensions of which are due to the size of industrially produced extruders and the lack of transformation. Small dimensions of the platform are possible only if non-standard equipment is used, but this leads to an increase in the cost of installation.

Utility Model Disclosure

The developers were faced with the task of creating a mobile installation for the production of extruded products, with the possibility of year-round use and high maneuverability when using standard industrial equipment.

The positive technical results achieved by using the proposed utility model include expanding the functionality of the installation by ensuring the possibility of its all-weather use, increasing the maneuverability of the installation, increasing the safety and reliability of the installation by improving the operating conditions of equipment and personnel.

The solution of this problem and the achievement of the aforementioned technical results became possible in the proposed mobile installation for the production of extruded products containing a wheeled vehicle with a platform and a hopper for raw materials, an extruder, a storage tank of the product emerging from the extruder, a grinding device, and a finished discharge means product. According to the claimed utility model, the installation is equipped with a container type module (in short - a module) in which the mentioned production equipment is located. The module is made with the possibility of installing on a platform of a wheeled vehicle and with the possibility of increasing the useful internal volume while maintaining the transport dimensions of the module, it is equipped with a hood and technological hatches for the possibility of connecting the equipment located in it with external devices.

The container-type module used in the installation is similar to the well-known container-type wagons and vans placed on the platform of the vehicle for transportation to the place of operation. It has a metal frame and walls sheathed with insulating material. The room formed inside such a module is protected from wind, precipitation and cold temperature.

Thanks to the placement of production equipment in such a closed module, the all-weather use of the installation became possible, regardless of the ambient temperature and weather conditions: rain, snow, etc.

However, only a “closed”, weatherproof volume is not enough for reliable and uninterrupted operation of the installation, as The processes carried out by it are accompanied by high temperatures and increased vaporization due to high grain moisture. These problems increase most strongly in the autumn-winter cold season, accompanied by an increase in environmental humidity.

However, the installation is supposed to use standard industrial equipment, in particular an extruder, which, as you know, has significant dimensions. In this case, the second problem arises: to ensure the compactness of the installation during transportation and acceptable conditions for placing the equipment in the working position.

To solve the above problems and ensure comfortable working conditions for equipment and maintenance personnel, the module is equipped with a good ventilation system and is configured to increase the useful internal volume due to its equipping with a special transformation mechanism.

Due to the possibility of transformation, they increase the useful volume of the module in the working (stationary) position of the installation. This makes it possible to improve ventilation conditions, more spaciously position equipment, thereby improving the conditions for its cooling and maintenance, which is especially significant when you consider that in a limited space you need to place 7-8 drives.

At the same time, the possibility of transformation allows you to save the transport dimensions of the module, which is necessary for the ability to move the installation on wheeled vehicles, compliance with the “transport dimensions” established by the rules of movement. The result is a high maneuverability of the installation.

The presence of technological hatches in the module allows connecting additional (external) equipment to the installation, for example, a device for primary processing of raw materials, a device for packaging and packaging of the finished product, which further expands the possibilities of using the installation.

Pipelines connecting the equipment located in the module with external devices are passed through technological hatches.

Due to the possibility of increasing the useful volume of the module in working condition, it became possible to form a utility compartment, isolated from the production part by a blank partition with a doorway. Such a compartment can be used to create a resting place for staff whose improved working conditions will positively affect the quality and safety of its work.

The control panel for electric drives of equipment can also be placed here. The removal of control equipment from a production room with high humidity to a drier isolated room helps to increase the safety and reliability of the installation.

In a specific implementation example of the installation, the transformation mechanism is located behind the rear hinged doors of the module and includes hinged panels pivotally connected to the roof and the base of the housing, forming a roof and floor of an additional volume, and sliding panels connected to the said hinged panels by means of quick couplings with the formation of side and rear walls additional volume. This solution is simple and adaptable installation work.

At least one door in its side wall serves to access the inside of the module.

In the preferred case of the implementation of the proposed installation, the container-type module is equipped with external outriggers: retractable, swivel or removable. The presence of such supports allows without the use of lifting means to transfer the module from the transport position to the working one and vice versa.

After delivery to the place of operation, the module is mounted on supports, which contributes to the stability of the module, and also allows you to remove the transport platform from under the module and use it for additional purposes.

The hood design preferably includes a lifting pipe-cover installed in the technological hole of the roof, and an exhaust fan mounted on the swing frame with the ability to move between two fixed positions: the worker with the placement in the technological hole of the roof and transport - with the fan inside the module. This design of the hood helps preserve the transport dimensions of the module.

In a preferred embodiment of the utility model, the grinding device is made in the form of a hammerless rotor crusher, the input of which is connected by a storage tank of the product emerging from the extruder, and the means for unloading the finished product are made in the form of a pneumatic conveying system associated with the output of the above crusher.

External devices may include means for preparing raw materials and a bag-loading complex for packaging the finished product, which are placed on a second vehicle for delivery to the place of operation of the installation.

Means for the preparation of raw materials usually include a hopper for the preparation of raw materials, equipped with a mixer and / or grinder.

Depending on the quality of the raw materials to be processed, either a screw conveyor or a pneumatic conveying system including a source of compressed air, a pneumatic conveyor and a cyclone precipitator connected to a raw material silo feeding the extruder is used to move it.

The connection of the installation with the bag-loading complex provides the possibility of a full cycle of processing of raw materials with automatic packaging and packaging of the final product.

The bag loading complex preferably has a pneumatic distribution system for packaging the finished product. The use of pneumatic conveying during packaging of the finished product contributes to the high productivity of packaging work and allows to exclude from the complex special cooler devices that take place in the prototype and known similar installations. The finished product, already partially cooled and dried in the storage tank of the product emerging from the extruder, dries well, cools and is ground during its movement in the air stream. As a result, well-dried product is packaged in bags, which contributes to its safety until use.

Utility Model Implementation

A mobile installation for the production of extruded products contains (see Fig. 1, 2) a wheeled vehicle with a platform 1 and module 2 of the container type (hereinafter - module 2) with production equipment located in it.

Module 2 is made with the possibility of installation and fixing on the platform 1 of a wheeled vehicle and with the possibility of increasing the useful internal volume while maintaining the transport dimensions of the module.

Module 2 is equipped with a hood 3, technological hatches 4, removable outrigger supports 5, window 6 and doorways 7 and rear hinged doors 8, behind which there is a transformation mechanism that provides the creation of an additional useful volume of the module.

As a wheeled vehicle moving the installation to its place of operation, a trailer (see Fig. 1), or a semi-trailer coupled to a towing vehicle, or a self-propelled device, for example, a truck (see Fig. 2) can be used.

After arriving at the destination, the installation is deployed and module 2 is put into working position. For this, the module 2 is installed on the outrigger supports 5 and the platform 1 is brought out from under it (see Fig. 3), after which the module is transformed.

The rear hinged doors 8 are opened, behind which, in the transport position, elements of the transformation mechanism are hidden, including wall panels connected to each other to form an additional volume (see Fig. 4).

The hinged panels 9 and 10 are rotated, pivotally mounted respectively on the roof and the base of the module 2. Supporting supporting elements 11 are installed under the lower panel 10 (see Fig. 5). Consecutively install the side folding panels 12 and 13, connecting them to the panels 9 and 10 through quick disconnect connections. In this case, the panels 9 and 10 form, respectively, the roof and floor of the additional volume 14, and the panels 12 and 13 form the side and back walls of this volume. The implementation of the panels 12 and 13 of two articulated interconnected parts helps to reduce installation work.

The example of the implementation of the transformation mechanism is preferable, but does not exclude the possibility of its implementation in another way.

The internal volume of module 2 is divided by a partition 15 into two rooms: the production compartment 16, in which the equipment is located, and the compartment 17, in which a place for staff to relax and a shield 18 for controlling the equipment’s electric drives is arranged (see Fig. 6, 7).

The equipment located in module 2 includes a raw material hopper 19, an extruder 20, a storage tank 21 of the product emerging from the extruder, a grinding device in the form of a hammerless rotor crusher 22, and means for unloading the finished product.

After the transformation of module 2, the equipment is prepared for operation, for which it is placed in the technological sequence, connecting, if necessary, with transport pipelines. The rotary crusher 22 is carried out and placed in an additional volume 14 of module 2. The input of the crusher 22 is connected to the storage tank 21, and the output to the pneumatic conveying system for unloading the finished product.

The presence in the walls and roof of module 2 of technological hatches 4 provides the ability to connect equipment located in the module with external devices placed outside the module walls that may be required for preparing raw materials or for packaging the finished product.

In the process of transportation of the installation, external equipment is placed on a second vehicle, for example, in the back of a truck moving a trailer with module 2.

At the same time, the possibility of using existing local reserves that do not require transportation as an external equipment is possible.

In a specific embodiment (see FIG. 6), a hopper 23 for preparing raw materials equipped with a mixer and / or grinder is installed outside the module 2.

Depending on the quality of the raw material, to move it from the hopper 23 to the hopper 19, either a screw conveyor (not shown) or a pneumatic conveying system including a compressed air source 24, a pneumatic conveyor 25 and a cyclone precipitator 26 connected to the raw material hopper 19 by a pipe 27 are used passed through the hole of the technological hatch 4 in the roof of the module 2.

Outside of module 2, a bag-loading complex 28 with a pneumatic distribution system for packaging the finished product is also placed.

The work of the complex is as follows.

The feedstock is poured into the hopper 23 to prepare the feedstock. As a raw material, various types of crops can be used, as well as grain affected by a fungus mixed with good raw materials.

Under the pressure of the compressed air created by the source 24, the feed from the hopper 23 rises through the pneumatic conveyor 25 and enters the cyclone 26, where it is deposited and lowered through the pipe 27 into the feed hopper 19, providing power to the extruder 20.

Extrusion is carried out at a temperature of 110-170 ° and pressure in the head zone of 40-60 atmospheres. When raw materials exit the extruder head as a result of a sharp drop in external pressure, an explosion occurs at the cellular level. The steam present in the raw material melt instantly evaporates and is sucked off using an extractor 3. The resulting porous product undergoes a structural transformation (degradation, hydrolysis). In this processing, the grain that starts to deteriorate is converted into a new product with useful properties, which can be stored for a long time. The knife device of the head of the extruder 20 provides cutting of the outgoing strand strips into granules of a given length, which fall into the container 21, where they are partially cooled and stabilized by the action of cooler ambient air.

The process is monitored by a worker. When the tank 21 is full, it includes a crusher drive 22, which simultaneously functions as a centrifugal pump of the pneumatic conveying system for unloading the finished product. Under the action of air discharge, the product from the tank 21 is drawn through the central hole into the crusher 22, where it is crushed by the action of its blades and thrown through the outlet pipe into a pipe 29 connected to the distribution manifold 30 of the bag-loading complex 28. During the movement under the influence of air flows, the crushed product is additionally It is cooled and dried. As a result, well-dried and ground feed is packaged in bags.

The use of pneumatic transport contributes to high productivity.

In FIG. Figure 8-10 shows the design of the hood 3 used in module 2, which includes a lifting pipe-cover 33 installed in the technological hole 31 of the roof 32 of module 2, and an exhaust fan 34 fixed by means of a swing frame 35 with the possibility of moving between two fixed positions: working and transport . In the operating position (see Fig. 8), the pipe-cover 33 is raised, the fan 34 is placed in the technological hole 31 of the roof 32. Upon completion of work, the frame 35 is rotated and the fan 34 is turned inside the volume of module 2, the pipe-cover 33 lower, closing the ventilation hole 31 (see Fig. 9).

The hood design ensures the compactness of the module in the transport position and the security of the interior space with the equipment during transportation.

The proposed mobile installation is characterized by the possibility of all-weather use and provides a full cycle of processing of raw materials with packaging of the final product.

The transport dimensions of the installation correspond to the dimensions of road transport, which contributes to its high maneuverability and the ability to move on any roads.
