Description

Aerator grate

technical field

The present invention relates to the technical field of wood stoves, and more particularly to the technical field of wood stove grates.

Background technique

Wood stove is a kind of heating and heating equipment widely used in rural and township areas in winter. When using wood stove, it is generally placed indoors. It is burned by adding fuel such as wood straw to the interior, and the heat generated by combustion is used for heating and burning. Water or cooking, etc., the smoke generated by the combustion of the wood stove is exhausted to the outside through a smoke exhaust pipe. At present, the common wood stove is mainly composed of the furnace surface, the hearth, the hearth, the grate and the ash cavity box. The furnace grate is mostly a fence-type structure. However, the furnace grate with this structure has the following shortcomings: First, the structural design is not very reasonable, the ventilation and oxygenation effect is poor, and the ash leakage groove on the furnace grate is easily damaged. The furnace ash is blocked, so that the oxygen demand for fuel combustion in the furnace cannot be well met, resulting in insufficient fuel combustion and low thermal energy utilization rate, which is not very energy-saving and environmentally friendly; the second is the use of traditional wood stoves. The suction effect is poor, so that the flue gas in the furnace is easy to escape into the room from the damper, etc., which seriously affects the indoor environment.

SUMMARY OF THE INVENTION

The purpose of the present invention is to solve the above deficiencies and provide a kind of good ventilation and oxygen-enhancing effect, which can improve the thermal energy utilization efficiency, is very energy-saving and environmentally friendly, and can enhance the suction strength of the fireworks in the furnace, and avoid the pollution of flue gas escaping. Aerator grates for indoor environments.

The technical solutions adopted by the present invention in order to solve the above-mentioned technical problems are as follows:

The aerator grate includes furnace teeth and an oxygenation cylinder, the oxygenation cylinder is fixedly installed at the center of the furnace teeth, the top of the oxygenation cylinder is closed, and the bottom is open. A through hole is opened on the peripheral wall of the aerator cylinder.

The furnace teeth include annular furnace racks, the diameters of the annular furnace racks are enlarged in turn, the annular furnace racks are stacked in sequence, and are fixedly connected by connecting racks, and the oxygen-enhancing cylinder is located in the innermost annular furnace rack, and the oxygen The drum is fixedly connected with the annular furnace frame through the bracket.

The annular hob is replaced by a square hob.

The furnace teeth are composed of an outer ring and a row of racks that are fixed and located in the outer ring, and the aerator cylinder is located at the center of the outer ring and is fixed by the row of racks.

The outer ring is annular or square.

The furnace teeth are composed of an outer ring, an inner ring and a row of racks. The row of racks is fixed between the outer ring and the inner ring. The aerator is located inside the inner ring and is connected to the outer ring through a bracket. Ring fixed connection.

The outer ring and the inner ring are respectively annular or square.

The connecting frames are distributed in a ring shape, the connecting frame is welded and fixed on the bottom of the annular furnace frame, one end of the support is welded and fixed on the aerator cylinder, and the other end of the support is welded and fixed on the connecting frame or the annular furnace frame.

The through holes are in 1-10 rows, and the number of holes in each row is 3-8.

The through hole is located at the top of the closed aerator cylinder.

The beneficial effects that the present invention can achieve by adopting the above-mentioned technical solutions are:

1. Use the annular or strip-shaped upward ventilation channel formed by the furnace teeth, set up an oxygenation cylinder at the center of the furnace teeth, and then open a horizontal through hole on the peripheral wall of the oxygenation cylinder above the furnace teeth to form lateral ventilation. It radiates the upward ventilation part of the entire furnace tooth, and integrates the horizontal ventilation of the aerator and the upward ventilation of the furnace tooth, so as to achieve the effect of oxygen supply in a mixed direction, which not only overcomes the weakness of the existing furnace teeth to be ventilated upwards in a single direction Moreover, the horizontal ventilation can also effectively remove the ash on the surface of the furnace teeth, and has a certain ash cleaning function to prevent the upward ventilation channel of the furnace teeth from being blocked and affecting the oxygen supply effect.

2. The teeth of the traditional wood stove are all ventilated upwards in a single direction, forming a single power for the fire in the hearth to rise. With the increase of temperature, it is easy to cause the burning speed of the fire in the hearth to increase sharply, resulting in the burning of wood too fast and easy. Causes furnace smoke to escape from the furnace face. In the aerator grate of the present invention, the height of the lateral through holes of the aerator cylinder is higher than the upward ventilation part of the furnace teeth, even if the upward ventilation part of the furnace teeth is blocked by furnace ash, by virtue of the lateral ventilation effect of the aerator cylinder, the aeration cylinder The horizontal through holes of the furnace have a certain suppressing effect on the ventilation of the furnace teeth, which prolongs the burning time of the inner furnace fire. In addition, because the height of the aerator cylinder is higher than the top of the furnace teeth, the air intake of the aerator cylinder can re-inject oxygen to the burning fire above the furnace teeth, especially the fire with smoke, which plays a good role in warming and warming. It has the effect of eliminating smoke, and greatly saves the amount of firewood, and improves the overall temperature of the stove.

3. When the aerator grate is in use, the upper part of the aerator can be directly embedded into the fuel in the furnace, so that the air can directly enter the fuel through the through hole of the aerator, and the ash can be removed from the adjacent furnace. The gap between the teeth is discharged, the air intake and the ash discharge do not interfere with each other, and there will be no problem of poor air intake caused by the traditional grate being easily blocked by the furnace ash, which makes the air intake very smooth and provides fuel for the combustion of fuel. Sufficient oxygen is generated, the fuel is fully burned, the utilization rate of heat energy is maximized, and it is very energy-saving and environmentally friendly. The furnace teeth are stacked in sequence or distributed in a row, which not only makes the furnace ash easier to discharge from the gap between adjacent furnace teeth, accelerates the ash discharge speed, and minimizes the shielding of the furnace dust from the air entering the furnace. It further improves the smoothness of air intake, and can make the air flow distribution into the furnace from the gap between adjacent furnace teeth more uniform, provide sufficient oxygen supply for the fuel in each position in the furnace, and make the fuel burn more fully and comprehensively. , which further improves the fuel combustion efficiency and thermal energy utilization rate, and the firewood saving effect is very significant, which can save a large amount of fuel costs for the users of the wood stove, and at the same time, it has a positive effect on energy saving and emission reduction, reducing firewood felling and protecting the ecological environment. It has a very important promotion significance.

4. The through hole on the aerator can also be set on the closed top, which can not only supply oxygen directly from the top to the fuel burning in the furnace, but also play a certain role in cleaning dust. Of course, through holes can be opened on the top and the peripheral wall of the aeration cylinder, so that a three-dimensional oxygen supply and ventilation can be formed.
