Description

Technical Field

[0001] The invention relates to the technical field of heat treatment, and in particular to a heat treatment device for metal components of an incinerator. Background Art

[0002] An incinerator is a harmless treatment equipment used for the harmless treatment of medical and domestic waste and animals. Its principle is to use the combustion of fuels such as coal, oil, and gas to burn and carbonize the objects to be treated at high temperatures to achieve the purpose of disinfection.

[0003] There are many metal components in the incinerator, among which the grate grating is one of the important components of the incinerator. The grate grating is responsible for supporting and burning waste in the incinerator. The grate grating is usually made of high-temperature alloy steel or other high-temperature resistant alloy materials. In the incineration process, the grate grating needs to withstand high temperature, high pressure and corrosive environment, and at the same time needs to have sufficient strength and wear resistance to ensure the normal operation of the incinerator.

[0004] Generally, grate grates are made by casting and then strengthened by heat treatment. The existing grate grating heat treatment device is a common heat treatment furnace. Although this heat treatment furnace can heat treat multiple grate grates at one time, these grate grates are stacked on each other and have poor air permeability. Some dead corners of the grate grates are difficult to be effectively heat treated, which will directly affect the strength and quality of the grate grates. At the same time, the heat treatment furnace is not a fully enclosed heating type. Generally, a moving mechanism for a material holding rack will be installed on the lower side, so a heating structure is generally not installed on the lower side. The upper side of the stationary grate grates is heated more, and the lower side is heated less. In this way, there will be differences in heat treatment due to different placement heights, which is not conducive to ensuring the overall heat treatment effect of the grate grates.

Except for the connecting seats 221 at the front and rear ends, the lower end centers of the remaining connecting seats 221 are hinged with connecting arms 222, and the connecting arms 222 are hingedly connected end to end in a V-shape.

[0038] See also Figure 1 , Figure 3 , Figure 4 and Figure 6 The upper pressure assembly 21 includes an inclined guide groove 212 between the adjacent upper and lower supporting rods 26 and penetrating through the front and rear mounting rotating plates 233 and all the squeezing plates 223.

[0041] See also Figure 2 , Figure 3 , Figure 4 and Figure 5The distance adjusting component includes two groups of through holes opened on the lower side of each connecting seat 221, and a guide rod 224 passes through the two groups of through holes without contact. The two ends of the guide rod 224 are respectively fixedly connected to the front and rear mounting rotating plates 233, and the two through holes of the front connecting seat 221 are fixedly connected with a mounting sleeve 227. The left mounting sleeve 227 is slidably connected to the left guide rod 224. The right guide rod 224 is provided with a screw segment 225 at a position corresponding to the front connecting seat 221. The right mounting sleeve 227 is threadedly connected to the screw segment 225. The front end of the right guide rod 224 extends to the outside of the sealing door 4 and is fixedly connected to the output end of the motor 226. The motor 226 is fixedly connected to the sealing door 4.

[0048] During specific operation, when the locking mechanism 2 rotates as a whole, the abutment plate 27 can limit the large end of the grate grate to avoid being affected by gravity. When the large end of the grate grate rotates to the lower side, the friction between the squeezing assembly 22 and the upper pressure assembly 21 is insufficient and slippage occurs. When the small end of the grate grate rotates to the lower side, the distance between the upper pressure assembly 21 and the supporting rod 26 is much smaller than the thickness of the large end of the grate grate, and the grate grate will remain stationary without slipping.

Through the synchronous movement of the connecting seats 221, the two adjacent connecting seats 221 drive the two pairs of squeezing plates 223 to press the sides of each column of grate grate.

[0052] S3: The motor 3 242 controls the long screw rod 241 to rotate and drive the mounting frame 25 and the sealing door 4 to move along the guide rod 2 243 as a whole, and the mounting frame 25 and the sealing door 4 are sent into the heat treatment furnace 3 as a whole, and the heat treatment furnace 3 is fully sealed by the sealing door 4.

[0053] S4: The heating resistor 31 is energized by an external power supply, and the gear 231 is controlled by the motor 232 to drive the ring gear frame 234 to rotate, and the ring gear frame 234 drives the front side mounting turn plate 233 to rotate, and the locked grate grating is driven to rotate by the mounting turn plate 233 to perform uniform heating until the grate grating is heat-treated, and then the unloading work is performed.
