Description

Technical Field

[0001] This utility model relates to an incinerator device, and more particularly to a grate for a waste incinerator. Background Technology

[0002] The mechanical grate of a waste incinerator transports waste through the reciprocating motion of grate bars. The grate bars operate in a harsh environment, experiencing high-temperature oxidation and chemical corrosion from the high temperatures generated by waste combustion and corrosive gases within the waste. Furthermore, they suffer frictional wear from the pressure and friction caused by hard objects within the waste during transport. Therefore, grate bars have a limited service life. If they are severely worn and can no longer be used, they must be replaced during a shutdown maintenance of the waste incinerator. To ensure wear resistance and corrosion resistance, grate bars are typically made of relatively expensive materials. Replacing the entire grate results in material waste and high costs for spare parts. Utility Model Content

[0003] The purpose of this invention is to provide a waste incinerator grate that is more material-saving and has a lower cost.

[0004] To achieve the above objectives, this utility model provides a grate for a waste incinerator, comprising a base and a top cover. One end of the base 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 an installation end. The upper surface of the top cover forms a first end slope and a second end slope. The top cover is detachably connected to the base, and the top cover is located on top of the first end of the base.

[0005] Furthermore, the top of the first end of the base is provided with a first connecting surface, a second connecting surface, and a third connecting surface connected in sequence, and the bottom of the top cover is provided with a fifth connecting surface, a sixth connecting surface, and a seventh connecting surface. The first connecting surface and the fifth connecting surface are inclined surfaces, the second connecting surface and the sixth connecting surface are horizontal surfaces, and the third connecting surface and the seventh connecting surface are vertical surfaces. When the top cover is located at the top of the first end of the base, the first connecting surface and the fifth connecting surface are in contact with each other, the second connecting surface and the sixth connecting surface are in contact with each other, and the third connecting surface and the seventh connecting surface are in contact with each other.

[0006] Furthermore, both the base and the top cover are plate-shaped bodies. One end of the top cover is the first end, and the other end is the second end. The fifth connecting surface is located at the first end of the top cover, and the seventh connecting surface is located at the second end of the top cover. A space for accommodating the top cover is formed between the first connecting surface and the third connecting surface of the base.

[0007] Furthermore, the second end of the top cover is also provided with a support section, which protrudes beyond the seventh connecting surface along the length direction. The upper surface of the support section forms an eighth connecting surface. The side of the base adjacent to the third connecting surface and located at the bottom is a fourth connecting surface. When the top cover is located at the top of the first end of the base, the fourth connecting surface is in contact with the eighth connecting surface and the support section is located below the base.

[0008] Furthermore, the inner wall of the base is provided with a first protrusion, the upper edge of the first protrusion being located within the second connecting surface, the inner wall of the top cover is provided with a second protrusion, the lower edge of the second protrusion being located within the sixth connecting surface, when the top cover is located at the top of the first end of the base, the upper edge of the first protrusion and the lower edge of the second protrusion are in contact, the first protrusion is provided with a connecting hole, the second protrusion is provided with a connecting groove, and the connector passes through the connecting hole and extends into the connecting groove to detachably connect the base and the top cover.

[0009] Furthermore, the connecting hole is a smooth hole, the inner wall of the connecting groove is provided with threads, and the connecting component is a bolt.

[0010] Furthermore, there are three of each of the connecting holes, connecting grooves, and bolts, and the connecting holes, connecting grooves, and bolts correspond one-to-one. The three connecting grooves are arranged sequentially along the width direction of the top cover.

[0011] Furthermore, the top cover is provided with ventilation holes.

[0012] Furthermore, the ventilation hole forms a cone shape from the air inlet direction to the air outlet direction.

[0013] Furthermore, it also includes multiple reinforcing ribs, which are disposed on the bottom surface of the base and are arranged sequentially along the length direction of the base.

[0014] The grate bars of this waste incinerator have at least the following beneficial effects:

[0015] This utility model relates to a grate for a waste incinerator. Because the top cover and the base are detachably connected, and the top cover is located at the top of the first end of the base, the top cover accounts for a small proportion of the overall weight of the grate. Replacing each grate can save a lot of materials, greatly reducing the overall cost of the grate and spare parts. In addition, the top cover concentrates the easily worn parts of the grate, while there are no easily worn parts on the base, which extends the service life of the base and further reduces costs.

[0020] like Figure 1 As shown, this utility model discloses a grate for a waste incinerator, comprising a base 11 and a top cover 12. One end of the base 11 is designated as a first end, and the other end as a second end. The first end is used for pushing and pulling waste, and the second end is the 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 is used for pushing and pulling waste. The most easily worn parts are concentrated on the raised areas where the head directly contacts the waste, especially around the air outlet, i.e., the area around the top cover 12. When the top cover 12 is severely worn, it can be removed and replaced with a new one, while the base 11 continues to be used. This utility model relates to a grate for a waste incinerator. Since the top cover 12 is detachably connected to the base 11, and the top cover 12 is located at the top of the first end of the base 11, the top cover 12 accounts for a small proportion of the overall weight of the grate. Replacing each grate can save a lot of material. In this embodiment, the weight of the top cover 12 accounts for only about 15% of the overall weight of the grate. Replacing each grate can save about 85% of the material, greatly reducing the overall cost of the grate and the cost of spare parts. Furthermore, the top cover 12 concentrates the easily worn parts of the grate, while there are no easily worn parts on the base 11, which extends the service life of the base 11 and further reduces costs.

[0021] Optionally, such 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 inclined surfaces, the second connecting surface 112 and the sixth connecting surface 122 are horizontal surfaces, and the third connecting surface 113 and the seventh connecting surface 123 are 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, and the first connecting surface 111 and the fifth connecting surface 121 are both inclined surfaces, while 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 plates push the waste to be incinerated through periodic linear reciprocating motion. The direction from the second end of the base 11 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 moving forward, the top cover 12 moves forward synchronously with the base 11 due to the pressing force between the mutually fitting third connecting surface 113 and the seventh connecting surface 123 and the frictional force between the mutually fitting second connecting surface 112 and the sixth connecting surface 122. When the base 11 moves backward, the top cover 12 moves backward synchronously with the base 11 due to the pressing force between the mutually fitting first connecting surface 113 and the fifth connecting surface 123 and the frictional force between the mutually fitting second connecting surface 112 and the sixth connecting surface 122. During the reciprocating motion of the grate bars, the top cover 12 is prevented from detaching from the base 11, thus extending the service life of the grate bars in the reciprocating motion environment.

[0022] Optionally, both the base 11 and the top cover 12 are plate-shaped bodies. 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. 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 section 125. The support section 125 protrudes beyond the seventh connecting surface 123 along its length. The upper surface of the support section 125 forms an eighth connecting surface 124. The side of the base 11 adjacent to the third connecting surface 113 and located at the bottom is a fourth connecting surface 114. When the top cover 12 is located at the top of the first end of the base 11, the fourth connecting surface 114 and the eighth connecting surface 124 are in contact, and the support section 125 is located below the base 11. In this embodiment, three support sections 125 are provided, and two or more support sections 125 may also be provided. The upper surface of the top cover 12 forms a first end slope near the first end and a second end slope near the second end. Because the top cover 12 has a first end slope and a second end slope, when the top cover 12 and the base 11 move backward synchronously, the second end slope of the top cover 12 is resisted by the garbage. The garbage resistance 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 a pressing force. The pressing force generates a clockwise moment on the top cover 12. This moment balances the aforementioned tilting moment, which prevents the top cover 12 from separating from the base 11 and further extends the service life of the grate bars.

[0024] Optionally, the inner wall of the base 11 is provided with a first protrusion 115, the upper edge of the first protrusion 115 is located in the second connecting surface, the inner wall of the top cover 12 is provided with a second protrusion 126, the lower edge of the second protrusion 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 protrusion 115 and the lower edge of the second protrusion 126 are in contact, the first protrusion 115 is provided with a connecting hole 116, the second protrusion 126 is provided with a connecting groove 127, the connector 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 waste to be incinerated on the grate plates during operation is first applied to the top cover 12, the first protrusion 115 and the second protrusion 126 increase the working area between the top cover 12 and the base 11, so that the top cover 12 and the base 11 jointly bear the pressure of the waste to be incinerated, thus preventing the top cover 12 from being damaged by pressure. At the same time, since the connector passes through the connecting hole 116 and extends into the connecting groove 127, it effectively avoids wear on the connector caused by high temperature primary air scouring, thus extending the service life of the connector.

[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 element is a bolt 13.

[0026] Optionally, three connecting holes 116, three connecting grooves 127, and three bolts 13 are provided, with each corresponding to one another. The three connecting grooves 127 are sequentially arranged along the width of the top cover 12. The three connecting grooves 127 on the top cover 12 are aligned with the three connecting holes 116 on the base 11, with the axial deviation between the connecting grooves 127 and the connecting holes 116 not exceeding 0.5mm. Three bolts 13 are passed through the connecting holes 116 of the base 11 and screwed into the connecting grooves 127 of the top cover 12, thus tightly connecting the top cover 12 and the base 11. The provision of three connecting holes 116, three connecting grooves 127, and three bolts 13 increases the connection strength between the top cover 12 and the base 11.

[0027] Optionally, such as Figure 4 As shown, the top cover 12 is provided with multiple ventilation holes 128. The primary combustion air enters the incinerator furnace through the ventilation holes 128, which plays a role in assisting the combustion of waste and drying the waste.

[0028] Optionally, the ventilation hole 128 is cone-shaped from the air inlet direction to the air outlet direction, with a cone top diameter of 15mm and a cone bottom diameter of 24mm.

[0029] Optionally, it also includes a plurality of reinforcing ribs 117, which are disposed on the bottom surface of the base 11. The reinforcing ribs 117 are arranged sequentially along the length of the base 11, thereby increasing the strength of the base 11 and enhancing its cooling and heat dissipation effect.

Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
