Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature rotary kiln door control, in particular to a high-temperature rotary kiln door control structure. Background Art

[0002] High temperature rotary kiln is widely used in metallurgy, chemical industry, building materials and other industries. It plays a vital role in improving product quality and production efficiency. High temperature rotary kiln is a rotating equipment. The materials in the kiln are constantly turned over as the kiln body rotates. Usually, in order to seal the port of the rotary kiln, a rotary kiln door is set at the port of the rotary kiln.

[0003] The existing rotary kiln doors are mostly opened and closed manually. The rotary kiln doors are relatively heavy and it takes time and effort for the workers to open and close the rotary kiln doors. At the same time, the sealing effect of the door gap between the two kiln doors of the rotary kiln is poor, which will cause heat loss inside the rotary kiln door.

[0004] Therefore, the utility model provides a high-temperature rotary kiln door control structure to solve the problems raised in the above background technology. Utility Model Content

The groove 102 is convenient for the later staff to add materials into the rotary kiln for processing. The position of the pressure plate 104 can be adjusted by the cylinder 103. The upper end of the sealing door 201 can be squeezed by the pressure plate 104 and the cylinder 103.

[0031] Reference Figure 2-4 The sealing mechanism 2 includes a sealing door 201, sealing strips 202 are fixedly arranged around the rear end of the sealing door 201, fixing rods 208 are fixedly arranged on both sides of the lower end of the sealing door 201, reinforcing ribs 206 are fixedly arranged at the rear end of the sealing door 201, two handles 207 are fixedly arranged in the middle of the front end of the sealing door 201, hinges 203 are fixedly arranged on both sides of the sealing door 201, connecting rods 204 are rotatably arranged inside the two hinges 203, and fixing rings 205 are fixedly arranged on one side of the two connecting rods 204.

[0032] The sealing door 201 can be used to seal the groove 102 opened at the front end of the kiln head cover 1 to avoid leakage of internal heat and gaps in the upper end of the sealing door 201, which may cause internal gas leakage. The sealing strip 202 can make the sealing door 201 and the kiln head cover 1 fit better, so as to avoid gaps between the sealing door 201 and the kiln head cover 1, which may cause internal gas leakage and waste of resources. The fixing rod 208 can be used in conjunction with the support rod 305 to exert a pulling force on the sealing door 201, which is convenient for adjusting the position of the sealing door 201.

The motor 303 can drive the screw rod 304 to rotate, and the support rod 305 can be fixed by the screw 304, which also facilitates the position of the support rod 305 to be adjusted later. The sealing door 201 can be moved to both sides by using the support rod 305 in conjunction with the fixing rod 208.

[0035] Working principle: Fix the kiln head cover to the feed port of the rotary kiln. When adding materials to the rotary kiln, start the cylinder 103 to move the pressure plate 104 forward, remove the bolts at the upper and lower ends of the fixing ring 205, and then start the motor 303 inside the fixing box 301 to drive the screw 304. The position of the support rod 305 can be adjusted by rotating the screw 304. The sealing door 201 can be opened to both sides by moving the support rod 305 and cooperating with the fixing rod 208, which is convenient for the staff to add materials to the inside. The staff does not need to manually open the sealing door 201, and it can also prevent the staff from being scalded by the internal leaking gas during the door opening process. After the material is added, start the motor 303 to drive the screw 304 to rotate in the opposite direction, move the support rod 305 inward, and then cooperate with the fixing rod 208. Close the sealing door 201, then reset the cylinder 103 and cooperate with the pressure plate 104 to squeeze the upper end of the sealing door 201 to prevent gas leakage.
