A side wall grate of a garbage incinerator

Abstract

The present invention provides a side wall grate plate for a waste incinerator. The side wall grate plate is composed of a mounting assembly, a fixing seat and a cover plate. A slide groove is provided on the fixing seat, and a slide column is correspondingly provided on the cover plate. The fixing seat and the cover plate are plugged and fixed by the insertion of the slide groove and the slide column. The feature is that the insertion between the slide groove and the slide column has a compensation gap, and a high temperature resistant spring is also provided between the fitting surfaces of the cover plate and the fixing seat. The primary air pressure acts on the outer surface of the cover plate, and the pressure of the high temperature resistant spring acts on the inner surface of the cover plate.

Description

Technical Field

[0001] The invention relates to a grate plate of a garbage incinerator, in particular to a grate plate of a side wall of a garbage incinerator. Background Art

[0002] The existing side wall grate plate of the garbage incinerator is a split plug-in combination structure. The side wall grate plate is composed of a mounting assembly, a fixing seat and a cover plate, wherein the fixing seat has a slide groove, and a slide column is correspondingly arranged on the cover plate, and the fixing seat and the cover plate are plugged and fixed by plugging the slide groove and the slide column. During installation, the grate fixing seat is first fixed on the side walls on the left and right sides of the furnace body through the mounting assembly, and then the cover plate 1 is plugged and fixed on the fixing seat.

[0003] In the prior art, the side wall grate plates are fixed on the side walls on the left and right sides of the furnace body, and the outer side of the cover plate maintains a certain side wall gap with the grate inside the furnace, and this gap cannot be adjusted. Since the side wall gap is connected to the furnace bottom, the primary air enters the furnace from the furnace bottom through the side wall gap. The air volume of the primary air is positively correlated with the combustion rate of the garbage, and the size of the side wall gap is also positively correlated with the air volume of the primary air entering.

[0004] The problem is that due to the gap in the side wall of the existing waste incinerator when the side wall grate plates are installed, this gap allows primary air to enter the furnace from the bottom of the furnace from the side, resulting in the garbage on both sides of the furnace burning faster than the garbage in the middle burning slower, seriously affecting the normal operation of the waste incinerator. Summary of the invention

[0005] In order to solve the existing problems, the present invention provides a side wall grate plate of a waste incinerator. The side wall grate plate is composed of a mounting assembly, a fixed seat and a cover plate. A slide groove is provided on the fixed seat, and a slide column is correspondingly provided on the cover plate. The fixed seat and the cover plate are plugged and fixed by the insertion of the slide groove and the slide column. The feature is that the insertion between the slide groove and the slide column has a compensation gap, and a high temperature resistant spring is also provided between the fitting surfaces of the cover plate and the fixed seat. The primary air pressure acts on the outer surface of the cover plate, and the pressure of the high temperature resistant spring acts on the inner surface of the cover plate. Since the two forces are in opposite directions, the gap between the outer surface of the cover plate and the grate inside the furnace changes with the change of the primary air pressure. The side wall grate plate of a waste incinerator proposed by the present invention can change the flow distribution of the primary air in the furnace by adjusting the pressure of the primary air, thereby improving the waste incineration effect.

[0006] The technical solution adopted by the present invention to solve the technical problem is that the present invention provides a side wall grate plate of a garbage incinerator, wherein the side wall grate plate is composed of an installation component, a fixed seat and a cover plate, wherein a slide groove is arranged on the fixed seat, and a slide column is correspondingly arranged on the cover plate, and the fixed seat and the cover plate are plugged and fixed by the insertion between the slide groove and the slide column. During installation, the fixed seat is first installed and fixed on the side walls on the left and right sides of the furnace body through the installation component, and then the cover plate is plugged and fixed on the fixed seat. It is characterized in that when the slide groove and the slide column are inserted, a compensation gap is provided between the two, and the compensation gap can make the cover plate translate, and a high-temperature resistant spring is also provided between the fitting surfaces of the cover plate and the fixed seat, the primary air pressure in the furnace acts on the outer side surface of the cover plate, and the pressure of the high-temperature resistant spring acts on the inner side surface of the cover plate, and the directions of these two forces are opposite, and the gap between the outer side surface of the cover plate and the grate inside the furnace changes with the change of the primary air pressure.

[0007] Preferably, the elastic coefficient of the high temperature resistant spring is determined through design, and when the pressure of the primary wind acting on the outer side of the cover plate is less than the pressure generated by the high temperature resistant spring on the inner side of the cover plate, the outer side of the cover plate and the grate inside the furnace fit each other; when the pressure of the primary wind acting on the outer side of the cover plate exceeds the pressure generated by the high temperature resistant spring on the inner side of the cover plate, the high temperature resistant spring contracts, and the cover plate translates to create a gap between the outer side and the grate inside the furnace.

A slide groove is provided on the fixed seat, and a slide column is correspondingly provided on the cover plate. The fixed seat and the cover plate are plugged and fixed by the insertion between the slide groove and the slide column. It is characterized in that the insertion between the slide groove and the slide column has a compensation gap, and a high temperature resistant spring is also provided between the fitting surfaces of the cover plate and the fixed seat. The primary air pressure acts on the outside of the cover plate, and the pressure of the high temperature resistant spring acts on the inner side of the cover plate.

[0018] Figure 1 It is a structural schematic diagram of the existing side wall grate plate of the garbage incinerator. The figure shows that in the prior art, the side wall grate plate of the garbage incinerator is a split plug-in combination structure. The side wall grate plate is composed of a mounting assembly 4, a fixing seat 2 and a cover plate 1, wherein the fixing seat 2 is provided with slide grooves 2.1a and 2.1B, and the cover plate 1 is correspondingly provided with slide columns 1.1a and 1.1b, and the fixing seat 2 and the cover plate 1 are plugged and fixed by the insertion between the slide grooves and the slide columns. During installation, the grate fixing seat 2 is first installed and fixed on the side walls on the left and right sides of the furnace body through the mounting assembly 4, and then the cover plate 1 is plugged and fixed on the fixing seat 2.

[0019] Figure 1 It is shown in the figure that in the prior art, the side wall grate plates are installed and fixed on the side walls on the left and right sides of the furnace body, and the outer side surface 1.2b of the cover plate retains a certain side wall gap 3 with the grate inside the furnace, and this gap cannot be adjusted. Since the side wall gap 3 is connected to the furnace bottom, the primary air enters the furnace from the furnace bottom through the side wall gap 3. The amount of primary air is positively correlated with the combustion rate of the garbage, and the size of the side wall gap is also positively correlated with the amount of primary air entering. Therefore, since there is a side wall gap when the side wall grate plates of the existing garbage incinerator are installed, this gap allows the primary air to enter the top of the furnace from the side of the bottom of the furnace, resulting in the problem that the garbage on both sides of the furnace burns quickly while the garbage in the middle burns slowly, which seriously affects the normal operation of the garbage incinerator.

[0020] Figure 2-Figure 5 It is a schematic diagram of the structure of an implementation of the present invention, wherein: Figure 2 , Figure 3 It is a schematic diagram of the parts structure. Figure 4 , Figure 5 It is a schematic diagram of the usage status structure.

[0021] The figure shows that in this example, the side wall grate plate of the garbage incinerator is a split plug-in combination structure. The side wall grate plate is composed of an installation component 4, a fixed seat 2 and a cover plate 1, wherein the fixed seat 2 has a slide groove 2.1a, 2.1B, and the cover plate 1 is correspondingly provided with slide columns 1.1a, 1.1b, and the fixed seat 2 and the cover plate 1 are plugged and fixed by the insertion of the slide groove and the slide column. During installation, the grate fixed seat 2 is first installed and fixed on the side walls on the left and right sides of the furnace body through the installation component 4, and then the cover plate 1 is plugged and fixed on the fixed seat 2. Different from the prior art, in this example, there is a compensation gap between the slide groove on the fixed seat 2 and the corresponding slide column on the cover plate 1 when they are plugged in, and the compensation gap can cause the cover plate 1 to move horizontally. A high temperature resistant spring 6 is also provided between the fitting surfaces of the cover plate 1 and the fixed seat 2. The primary air acts on the outer side surface 1.2b of the cover plate 1, and the pressure of the high temperature resistant spring 6 acts on the inner side surface 1.2a of the cover plate. Since the directions of these two forces are opposite, during the operation of the incinerator, the elastic coefficient of the high temperature resistant spring 6 remains unchanged, but the pressure of the primary air can be adjusted. Therefore, the side wall gap 3 between the outer side 1.2b of the cover plate 1 and the grate inside the furnace changes with the change of the primary air pressure.

[0022] Figure 4 , Figure 5 It is shown that during the operation of the waste incinerator, the elastic coefficient of the high temperature resistant spring 6 is determined by design. When the pressure of the primary air acting on the outer side 1.2b of the cover plate 1 is less than the pressure generated by the high temperature resistant spring 6 on the inner side 1.2a of the cover plate 1, the outer side 1.2b of the cover plate 1 and the grate inside the furnace fit each other, and the primary air enters the furnace from the middle of the grate. When the pressure of the primary air increases, the primary air pressure acting on the outer side of the cover plate 1 exceeds the pressure generated by the high temperature resistant spring 6 on the inner side 1.2a of the cover plate 1, the high temperature resistant spring 6 contracts, the cover plate 1 moves horizontally, and a gap (i.e., the side wall gap 3) appears between the outer side 1.2b of the cover plate 1 and the grate inside the furnace. At this time, the primary air enters the furnace from the middle and both sides of the grate.

[0023] Figure 4 and Figure 5 It is shown that in this example, the flow distribution of the primary air in the furnace can be changed by adjusting the pressure of the primary air, thereby improving the waste incineration effect.
