Description

The utility model relates to the field of creating heat-intensive appliances for heating residential and non-residential premises and can be used in the construction of heat-intensive stoves and fireplaces using solid or gaseous fuels.

The construction of traditional stoves and fireplaces is a rather laborious and lengthy process, requiring professional skills. Special requirements are placed on the quality of the furnace, which is the "heart" of a fireplace or stove. It should provide further durability, uninterrupted operation and safe operation of the entire heating device. One of the main operational characteristics of the furnace of a stove or fireplace is its strength, tightness and the ability to accumulate heat. The durability and tightness of the furnace ensures that flue and carbon monoxide gases do not enter the room.

From the existing level of technology it is known to use ceramic kiln or fireclay bricks for the manufacture of heat-intensive furnaces of stoves and fireplaces, for example: clubpechnikov.ru.

The disadvantage of this technical solution is that the manufacture of heat-intensive furnaces requires a lot of time and special knowledge.

The closest in technical essence to the claimed technical solution is a furnace for stoves and fireplaces, which is a box and includes vertical walls, a ceiling and a flue gas exhaust hole, manufactured by Belfert fireplace, Moscow (http://ikamin.ru ) The furnace for stoves and fireplaces is made from specially manufactured blocks. Clay, sand, gypsum, etc. are used as material for blocks.

The disadvantage of this technical solution is the need for special equipment, additional room and raw materials for the manufacture of blocks from which the furnace is mounted.

The task to which the technical solution is directed is to create an easy-to-manufacture device with improved operational characteristics.

The problem in the claimed device is solved due to the fact that the furnace for a stove or fireplace, which is a duct and includes vertical walls, a ceiling and a hole for exhausting flue gases, according to the technical solution, consists of elements representing fireclay blocks made with the possibility of connection to each other by means of vertically arranged cutouts made in the wall of the block at the point of attachment of the adjacent block, while the elements are interconnected using a heat-resistant binder Properties.

The ends of the elements may have slots made with the possibility of filling with a heat-resistant binder.

The furnace can be equipped with a metal frame along the outer perimeter of its vertical walls.

The furnace can be equipped with a heat-resistant fence along the outer perimeter of its vertical walls.

The furnace can be equipped with a heat-resistant fence along the outer perimeter of its vertical walls, installed with an air gap relative to them. In this case, the air gap can be filled with mineral insulation.

The flue gas vent may be configured to mount a metal pipe therein.

The furnace may be provided with openings for placement inside the furnace channel for heating the medium.

The technical result provided by the given set of features is to increase the operational characteristics of the device by ensuring the tightness and strength of the finished product while reducing the time for its assembly due to the implementation of the furnace elements in the form of fireclay blocks made with the possibility of connection between each other by means of vertically located cutouts made in the wall of the block at the point of attachment of the adjacent block, as well as by connecting the elements together using thermo persistent binder.

The use of firebox elements in the form of chamotte blocks eliminates their fitting at the assembly site, which significantly reduces the time for its assembly, and vertically located cutouts made in the block wall at the attachment point of the adjacent block allow the firebox to be assembled as a constructor, and together with a heat-resistant binder, they provide strength and tightness of the structure as a whole.

To provide additional tightness and strength, the ends of the elements may have slots made with the possibility of filling with a heat-resistant binder.

Fireclay against kiln ceramic bricks has a 1.5-2 times greater specific gravity, which provides greater heat capacity and 2.5 times greater thermal conductivity, which accelerates the collection of thermal energy.

The essence of the claimed device is illustrated by drawings, not covering, and even more so, not limiting the scope of claims for this decision, but only being illustrative materials of particular cases of the device, which depict:

The furnace for a stove or fireplace is a box and includes vertical walls 1, floor 2 and a hole 3 for the removal of flue gases. It consists of elements 4, which are chamotte blocks. Fireclay blocks are made with the possibility of connecting with each other by means of vertically located cutouts 5 made in the wall of the block at the point of attachment of the adjacent block. Elements 4 are interconnected using a heat-resistant binder.

To provide additional tightness and strength at the ends of the elements 4, slots 6 are made with the possibility of filling with a heat-resistant binder. The slots 6 are made in the upper and lower parts of the elements 4. If the upper element 4 is superimposed on the element 4 in the transverse direction, then on it the slots 6 are made in the transverse direction at the places of application of the upper transverse element 4.

To provide additional strength, the furnace can be equipped with a metal frame 7 or heat-resistant fence 8 along the outer perimeter of its vertical walls 1. Heat-resistant fence 8 can be installed with an air gap relative to them (see Fig. 5). The air gap can be filled with mineral insulation 9 (see Fig. 6), which will also allow you to save heat in the furnace longer and increase the degree of tightness of the furnace.

The hole 3 for the removal of flue gases can be made with the possibility of installing a metal pipe in it. The furnace may be provided with openings for placement inside the furnace of the channel 10 for heating the medium. The channel 10 for heating the medium can be made in the form of a metal pipe, for example, kalach used to heat water or air in the furnace.

Make the oven as follows.

For the manufacture of fireboxes, standard rectangular-shaped chamotte blocks are used, produced by Russian factories in particular BKO JSC (http://aobko.ru).

At the assembly site of the furnace, vertically located cutouts 5 are made in the walls of chamotte blocks at the points of attachment of the adjacent block. To make cutouts 5, only hand tools and a cutting machine with a diamond blade up to 250 mm are used.

Of chamotte blocks of especially complex shapes manufactured at BKO JSC or other enterprises producing similar chamotte products of models SB-96 or SHA-96 with dimensions: width - 230 mm, thickness - 90 mm, length - 600 mm, and also ШБ- 94 or ША-94: width - 230 mm, thickness - 75 mm, length - 460 mm or their analogues with low cost for trimming the edges and creating shallow slots 6, it is easy to manufacture elements 4 that quickly assemble the furnace for creating heat-intensive furnaces and fireplaces. For the manufacture of individual elements, their standard length and width are reduced.

As a rule, the depth of the cutouts 5 on the elements 4 is 600 mm long and 90 mm thick does not exceed 20 mm, and the width is 75 mm or 90 mm, depending on the thickness of the end face of the adjacent element. To prevent the passage of gases between vertically arranged elements 4 along the length and width at the intersection with adjacent elements 4, cuts are made 3-4 mm wide and 4-5 mm deep so that they intersect on all elements 4 forming the perimeter furnaces of the furnace or fireplace. Slots 6 are performed in the upper and lower plane of the element.

The assembly of the furnace is carried out in order, the final stage of the assembly is the execution of elements 4 of the ceiling 2 and the hole 3 for the removal of flue gases.

As a heat-resistant binder, it is advisable to use heat-resistant paste or heat-resistant adhesive. For these purposes, you can use the thermally moisture resistant adhesive paste "Universal" (vvww.germeticplus.ru) or adhesive mastic NEOMID (manufacturer of ExpertEcology LLC www.neomid.ru). In this case, cutouts 5 and slots 6 are carefully glued, which allows you to create the necessary tightness and structural strength of the furnace. Installation of elements is usually carried out with an overlap on adjacent elements located below, which also increases the structural strength of the furnace. When assembling the elements, the places of cutouts 5 and slots 6 are filled with heat-resistant paste or glue, which provides increased tightness to prevent the passage of flue gases in the corner regions of the furnace and between the elements 4 located one above the other.

The heat-resistant fencing 8 of the furnace is preferably made of talc stone (talc chlorite, talc magnesite), brick, granite, marble, porcelain stoneware, heat-resistant tiles with decorative finishes and other heat-resistant materials. An air gap may remain between the firebox and the heat-resistant fence.

The air gap between the vertical wall 1 and the heat-resistant fence 8 provides heat conservation and, if necessary, accelerates the transfer of heat to heated rooms due to convection by passing air between the vertical walls 1 and the heat-resistant fence 8, if the heat-resistant fence 8 is equipped with air dampers at the top or bottom . In the absence of air holes in the heat-resistant fence 8, the air gap acts as a heat insulator. To improve thermal insulation properties, the air gap is filled with mineral insulation 9.

When using 8 ceramic bricks in the manufacture of heat-resistant fencing, including facing, you can not leave an air gap.

A chamotte firebox can be equipped with an oven and a special compartment for baking bread products. A firebox from chamotte elements is made and delivered in the form of individual elements from chamotte blocks made in special sizes, and assembled at the installation site using special heat-resistant glue. The furnace is a universal device, it can be used both in newly built stoves or fireplaces, and in the reconstruction of old ones. The application of this technical solution will allow even a person who does not have experience and professional skills in the construction of stoves to easily and quickly install a firebox, which during operation can more efficiently accumulate and use heat to heat rooms, as well as increase the life of stoves and fireplaces.
