Abstract
Description
Technical Field
[0001] The invention relates to an incinerator device, in particular to a grate plate of a garbage incinerator. Background Art
[0002] The mechanical grates of a waste incinerator transport waste through the reciprocating motion of the grate plates. These plates operate in a harsh environment. On the one hand, the high temperatures generated by the burning waste and the corrosive gases in the waste cause high-temperature oxidation and chemical corrosion. On the other hand, the friction and friction caused by the hard objects in the waste during transportation also cause friction and wear. Therefore, the grate plates have a limited service life. If they are severely worn and can no longer be used, they need to be replaced during the waste incinerator shutdown and maintenance. To ensure wear and corrosion resistance, the grate plates are usually made of relatively expensive materials. Replacing the entire grate plate results in material waste and high replacement costs.

[0020] like Figure 1 As shown, a grate plate for a waste incinerator according to the present invention comprises a base 11 and a top cover 12. One end of the base 11 is a first end, and the other end is a second end. The first end is used for pushing and pulling waste, and the second end is a mounting end. The top cover 12 is detachably connected to the base 11, and is located on top of the first end of the base 11. During use, the first end of the grate plate for a waste incinerator according to the present invention is used for pushing and pulling waste. Parts susceptible to wear are mainly concentrated at the raised portion where the head is in direct contact with the waste, especially the area around the air outlet, i.e., the location of the top cover 12. When the top cover 12 is severely worn, the top cover 12 is disassembled and removed, and replaced with a new top cover spare part, while the base 11 continues to be used. The present invention provides a grate plate for a garbage incinerator. Since the top cover 12 is detachably connected to the base 11 and the top cover 12 is located on the top of the first end of the base 11, the top cover 12 accounts for a relatively small proportion of the overall weight of the grate plate. A large amount of material can be saved each time a grate plate is replaced. In this embodiment, the weight of the top cover 12 only accounts for about 15% of the overall weight of the grate plate. About 85% of the material can be saved each time a grate plate is replaced, which greatly reduces the overall cost and spare parts cost of the grate plate. In addition, the top cover 12 concentrates the easily worn parts of the grate plate, and there are no easily worn parts on the base 11, which extends the service life of the base 11 and further reduces costs.
[0021] Alternatively, as Figure 2 、 Figure 3As shown, the top of the first end of the base 11 is provided with a first connecting surface 111, a second connecting surface 112, and a third connecting surface 113 connected in sequence, and the bottom of the top cover 12 is provided with a fifth connecting surface 121, a sixth connecting surface 122, and a seventh connecting surface 123. The first connecting surface 111 and the fifth connecting surface 121 are both inclined surfaces, the second connecting surface 112 and the sixth connecting surface 122 are both horizontal surfaces, and the third connecting surface 113 and the seventh connecting surface 123 are both vertical surfaces. When the top cover 12 is located at the top of the first end, the first connecting surface 111 and the fifth connecting surface 121 are in contact with each other, the second connecting surface 112 and the sixth connecting surface 122 are in contact with each other, and the third connecting surface 113 and the seventh connecting surface 123 are in contact with each other. Since the first connecting surface 111 and the fifth connecting surface 121 are in contact with each other, the second connecting surface 112 and the sixth connecting surface 122 are in contact with each other, and the third connecting surface 113 and the seventh connecting surface 123 are in contact with each other, the first connecting surface 111 and the fifth connecting surface 121 are both inclined surfaces, and the third connecting surface 113 and the seventh connecting surface 123 are both vertical surfaces, the top cover 12 is clamped between the first connecting surface 111 and the third connecting surface 113 of the base 11. During use, the grate piece pushes the garbage to be incinerated through periodic linear reciprocating motion. The direction in which the second end of the base 11 points to the first end of the base 11 is the forward movement direction, and the opposite direction is the backward movement direction. When the base 1 When the grate 1 moves forward, the top cover 12 moves forward synchronously with the base 11 due to the squeezing force between the third connecting surface 113 and the seventh connecting surface 123 that are in contact with each other, and the friction force between the second connecting surface 112 and the sixth connecting surface 122 that are in contact with each other; when the base 11 moves backward, the top cover 12 moves backward synchronously with the base 11 due to the squeezing force between the first connecting surface 113 and the fifth connecting surface 123 that are in contact with each other, and the friction force between the second connecting surface 112 and the sixth connecting surface 122 that are in contact with each other. During the reciprocating motion of the grate slices, the top cover 12 is prevented from being separated from the base 11, thereby extending the service life of the grate slices in a reciprocating motion environment.
[0022] Optionally, the base 11 and the top cover 12 are both plate-shaped, one end of the top cover 12 is the first end and the other end is the second end, the fifth connecting surface 121 is located at the first end of the top cover 12, and the seventh connecting surface 123 is located at the second end of the top cover 12, and a space for accommodating the top cover 12 is formed between the first connecting surface 111 and the third connecting surface 113 of the base 11.
[0023] Optionally, the second end of the top cover 12 is further provided with a support segment 125. The support segment 125 protrudes beyond the seventh connection surface 123 along its length. The upper surface of the support segment 125 forms an eighth connection surface 124. The side surface of the base 11 adjacent to the third connection surface 113 and located at the bottom is the fourth connection surface 114. When the top cover 12 is located on top of the first end of the base 11, the fourth connection surface 114 and the eighth connection surface 124 are in contact with each other, and the support segment 125 is located below the base 11. In this embodiment, three support segments 125 are provided, but two or more support segments 125 may also be provided. A first end inclined surface close to the first end and a second end inclined surface close to the second end are formed on the upper surface of the top cover 12. Due to the formation of the first end inclined surface and the second end inclined surface on the top cover 12, when the top cover 12 and the base 11 move backward synchronously, the second end inclined surface of the top cover 12 is subjected to the resistance of the garbage. The resistance of the garbage generates a tilting moment in the counterclockwise direction on the top cover 12. The eighth connecting surface 124 on the upper surface of the support section 125 and the fourth connecting surface 114 at the bottom of the base 11 fit together to generate an extrusion force. The extrusion force generates a moment in the clockwise direction on the top cover 12. This moment is balanced with the aforementioned tilting moment, thereby preventing the top cover 12 from separating from the base 11, thereby further extending the service life of the grate slices.
[0024] Optionally, a first boss 115 is provided on the inner wall of the base 11, and the upper edge of the first boss 115 is located in the second connecting surface; a second boss 126 is provided on the inner wall of the top cover 12, and the lower edge of the second boss 126 is located in the sixth connecting surface 122; when the top cover 12 is located at the top of the first end of the base 11, the upper edge of the first boss 115 is fitted with the lower edge of the second boss 126; a connecting hole 116 is provided on the first boss 115, and a connecting groove 127 is provided on the second boss 126; the connecting member passes through the connecting hole 116 and extends into the connecting groove 127 to detachably connect the base 11 and the top cover 12. Since the pressure of the garbage to be incinerated applied to the grate slices during operation first acts on the top cover 12, the effective area between the top cover 12 and the base 11 is increased by the first boss 115 and the second boss 126, so that the top cover 12 and the base 11 jointly bear the pressure of the garbage to be incinerated, thereby preventing the top cover 12 from being damaged by pressure. At the same time, since the connecting piece passes through the connecting hole 116 and extends into the connecting groove 127, the wear of the connecting piece caused by the scouring of high-temperature primary air is effectively avoided, thereby extending the service life of the connecting piece.
[0025] Optionally, the connecting hole 116 is a smooth hole, the inner wall of the connecting groove 127 is provided with threads, and the connecting piece is a bolt 13 .
[0026] Optionally, three connection holes 116, three connection grooves 127, and three bolts 13 are each provided, with each corresponding to the other. The three connection grooves 127 are sequentially arranged along the width of the top cover 12. The three connection grooves 127 on the top cover 12 are aligned with the three connection holes 116 on the base 11, and the axis deviation between the connection grooves 127 and the connection holes 116 does not exceed 0.5 mm. The three bolts 13 pass through the connection holes 116 of the base 11 and are screwed into the connection grooves 127 of the top cover 12, thereby tightly connecting the top cover 12 and the base 11. The provision of three connection holes 116, three connection grooves 127, and three bolts 13 increases the connection strength between the top cover 12 and the base 11.
[0027] Alternatively, as Figure 4 As shown, a plurality of ventilation holes 128 are provided on the top cover 12, and the primary combustion air enters the incinerator furnace through the ventilation holes 128, playing the role of assisting the combustion of garbage and drying the garbage.
[0028] Optionally, the ventilation hole 128 forms a cone from the air inlet direction to the air outlet direction, with a cone top diameter of 15 mm and a cone bottom diameter of 24 mm.
[0029] Optionally, a plurality of reinforcing ribs 117 are further included. The reinforcing ribs 117 are arranged on the bottom surface of the base 11 and are arranged in sequence along the length direction of the base 11. The reinforcing ribs 117 increase the strength of the base 11 and enhance the cooling and heat dissipation effect of the base 11.
[0030] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
