Description

The utility model relates to installations for the purification of small wastes of metallurgical production containing oil, lubricants or other types of liquids used in the grinding, polishing and cutting of metals and alloys and can be used to clean industrial wastes from liquid impurities without affecting the properties of the material being cleaned.

A three-stage compact plasma system for high-temperature waste treatment containing a furnace chamber is known from the prior art, while the furnace chamber lid contains openings for installing containers 5 (crucibles) with material to be cleaned therein. Tanks 5 are made in the form of vertical pipes with a plugged bottom and flat caps (US Application No. 20160138803, F23G 5/033, B09B 3/00, F23G 5/44, F23G 5/10, F23G 5/08, F23G 5/38, published 05/19/2016).

For the closest analogue to the patented solution, a device for the preliminary processing of oiled scrap metal (Copyright Certificate No. 1772567, F27D 13/00, published on 10/30/1992), containing a furnace, nozzles for supplying working heat, a container for the material to be cleaned, was adopted.

The disadvantages of the closest analogue are the overall complexity and cumbersome design, due to the use of a pallet with an annular tank filled with sand and reagent, knives for the formation of annular spaces for gas purification, a refrigerator, an afterburner, a fan, a filter, a sump. Also disadvantages are the high cost of time for installation of the structure, the high cost of fuel.

The technical problem that this utility model is aimed at is the creation of a compact, easy-to-assemble, install and operate plant for the treatment of metallurgical waste from oils, lubricants or other types of liquids.

The technical result achieved by the implementation of this utility model is to simplify the design used to clean metallurgical waste while maintaining its functionality, as well as increasing the compactness of the installation, increasing the reliability and durability of the installation as a whole, and reducing the cost of construction.

Due to the installation for the treatment of metallurgical waste containing a furnace chamber, a burner, containers for the material to be cleaned, a cover of the furnace chamber with holes for installing four containers for the material to be cleaned, made in the form of retorts connected to the receiving tank with flexible hoses, the location of the burner inside furnace chamber , the compactness of the installation as a whole and the simplification of the design, its assembly and installation due to the exclusion of auxiliary structural elements are ensured.

The manufacture of a waste treatment plant for metallurgical production according to the proposed layout eliminates the need for auxiliary structural elements, such as pumps, fans, electric heating elements, etc., which leads to the simplification of the design used for waste treatment of metallurgical production, while maintaining its functionality, and also increase the compactness of the installation, increase the reliability and durability of the installation as a whole, reduce the cost of construction.

In particular, in the upper part of the inner surface of the retorts there are rings mounted with an inclination towards the drain hole and designed to trap and drain the liquid phase. This additionally increases the compactness of the structure, the reliability and durability of the structure as a whole, reduces its cost and simplifies the design while maintaining its functionality by eliminating vacuum pumps from the installation to accelerate the discharge of waste. In this case, the rings located in the upper part of the inner surface of the retorts are made in the form of a gutter to increase the efficiency of capture and discharge of the liquid phase.

In particular, the furnace chamber is made of refractory material, which ensures the compactness of the installation as a whole and simplification of the design, its assembly and installation by eliminating auxiliary refractory elements.

Further, the claimed utility model is illustrated by drawings.

In FIG. 1 shows a General view of the installation for the treatment of waste from metallurgical production.

In FIG. 2 shows a top view of a plant for treating waste from metallurgical production.

In FIG. 3 shows a General view in section of a metallurgical waste treatment plant.

According to the claimed utility model, a metallurgical waste treatment plant consists of a furnace chamber 1, a furnace chamber cover 2 with at least one opening 3, a burner 4 installed in the furnace chamber 1, at least one retort 5 installed in the cover opening 3 2. Retorts are made in the form of vertical pipes with a blanked bottom, a flat cover and a discharge pipe 6 connected by a flexible metal hose 7 to a condenser 8, under the drain pipe 9 of which receiving tanks 10 are installed condensation of the liquid phase or separation of the liquid phases in the case of working with a mixture of liquid impurities. Rings 11 are welded inside the retorts, made in the form of a gutter and installed in the upper part of the retorts at an angle to the drain hole to accelerate the process of draining the liquid phase.

A metallurgical waste treatment plant is made of any refractory material that can withstand temperatures of 900 degrees Celsius and has a low coefficient of thermal conductivity, for example, of magnesite brick. The cross section of the furnace chamber 1 can be selected of any size and shape, depending on the installation location of the furnace and the productivity of the installation, which increases the convenience in operation, since it allows you to compactly place the installation in any place.

The cover 2 is made with four holes 3 under the retort 5, the cleaned material is loaded into the retort 5. The cross-section of the retorts, presented in the form of vertical pipes, can be selected of any size and shape. The number of retorts may vary depending on the required installation performance. The holes 3 in the lid of the furnace chamber can also be made of various shapes and sizes for the installation of the aforementioned retorts. The holes 3 in the lid of the furnace chamber allows you to install retorts directly into the furnace chamber, which allows to increase the compactness of the installation and simplify the assembly, installation and design as a whole, while maintaining its functionality. In various embodiments, it is possible that the number of retorts to be installed can be any, depending on the required installation performance. Cross-sections of retorts and holes for retorts can be made round, rectangular or any other suitable shape to enhance functionality.

Burner 4 can run on any fuel, for example, gasoline, kerosene, diesel fuel, etc. Including burner 4 can run on waste oil, i.e. on liquid waste of the cleaning process. Under the condition that the burner operates on used oil, the cost of the installation is further reduced, its operation is simplified. The use of burner 4 allows you to exclude from the design of the installation additional mechanisms for electrical heating, which are expensive and complicate the assembly, installation and design of the installation as a whole. Also, the use of a burner is an advantage, since it allows you to fully control the speed and stability of the process of purification of industrial waste from liquid impurities, to exclude the possibility of ignition of oil inside the retort.

The use of a retort 5 in the installation with a discharge pipe 6 for the removal of liquid waste vapors does not require the presence of additional elements connecting the retorts to the pipes, which simplifies the design used to clean metallurgical waste while maintaining its functionality. Retort outlet pipes are threaded to the side of the capacitors. This arrangement implies the shortest way for the liquid phase and vapor to drain into the condensers, which ensures the highest process speed.

The installation inside the retort of 5 rings 11 to speed up the process of draining waste and maintaining the purity of the material being cleaned, simplifies the design of the installation by excluding from the installation of vacuum pumps used in analogues.

The retorts 5 with the outlet pipe 6 are connected to the capacitor 8 using a flexible metal hose 7. At least one receiving tank of a special simplified design 10 is installed under the drain pipe 9 of the condenser 8. The design parameters of the tank 10 are selected for the performance of the installation. As receiving containers, any containers in which tightness can be achieved can be used.

Retort outlet pipes are hermetically connected to the capacitors by means of metal flexible hoses through threaded connections to ensure preservation of tightness. Flexible connection of metal hoses allows quick dismantling of the structure. A flexible connection provides tightness in the conditions of vibrations and other types of physical influences, the ability to perform installation functions in specified application conditions, thus increasing the reliability of the installation.

Since forced cooling of condensers is not used in the claimed installation for waste cleaning from oils, which implies the absence of pumps, fans or other devices requiring the cost of depreciation, maintenance and their purchase in principle, the installation mechanism as a whole is simplified while maintaining its functionality.

Installation works as follows.

The installation is selected the necessary size and shape to place it anywhere. Then, in four retorts, the material to be cleaned is loaded in any required amount into each, for example, 1000 kg. The quantity and mass of material loaded into the retorts can be reduced or increased to any quantity provided that the retorts are resized, which allows you to clean a large amount of material without installing additional structural elements and, as a result, without complicating the design. A cover is put on the retorts 5 and bolted through a sealed gasket to seal the retorts. The method of sealing through a sealed gasket provides the best clamp cover to the retort. Further, using any suitable lifting mechanism, the retorts are installed in the furnace body through 4 holes in the lid. The outlet pipes at the top of the retorts are threaded to the side of the capacitors. After installing the retort, the retort outlet pipes are hermetically connected to the capacitors by means of metal flexible hoses through threaded connections. Next, under the condenser drain pipe, receiving tanks are installed for draining liquid waste or for separating liquid phases in the case of working with a mixture of liquid impurities. In the case of phase separation, the number of capacities and the design of the capacitors are selected individually.

After turning on the burner, heating of the furnace space and retort begins. The optimum temperature inside the retort is 450 degrees Celsius, in the claimed installation, the temperature can reach 850 degrees, which allows to accelerate the evaporation of the liquid phase. An increase in the temperature inside the waste retorts and, as a result, acceleration of the waste treatment process leads to an increase in the size of the condenser, however, this does not complicate the design of the condenser, which is also an advantage of the metallurgical waste treatment plant. After heating the furnace space and the retort, the process of evaporation of the liquid phase from the retort begins, followed by condensation and discharge into the tank for the liquid phase.

Upon completion of the cleaning process, the retorts from the furnace are removed using any lifting mechanism, new retorts with material are installed in the furnace, and the cleaning process continues. The purified material from the retort is removed and a new one is loaded. After unloading, the material is analyzed for any moisture content. The residual content of the liquid phase varies from 0 to 0.1%.

Thus, the claimed utility model leads to a simplification of the design used to clean metallurgical waste while maintaining its functionality, as well as to increase the compactness of the installation, increase the reliability and durability of the installation as a whole, and reduce the cost of construction.
