Description

Technical Field

[0001] The utility model relates to the technical field of tunnel kilns, in particular to a continuous sintering tunnel kiln for electrode materials. Background Art

[0002] As a high-temperature industrial equipment, tunnel kiln is widely used in the production process of mineral products, electrode materials and other materials. Its special continuous operation mode enables tunnel kiln to achieve long-term high-temperature smelting, roasting and heat treatment, thereby meeting the industry's strict requirements on material properties. When processing electrode materials, it is usually carried out in the corresponding continuous sintering tunnel kiln.

[0003] However, with the development of materials science and the continuous improvement of industrial production efficiency, traditional tunnel kiln technology has gradually exposed some problems in the sintering process of electrode materials. Because sintering tunnel kilns achieve continuous conveying, the two ends of most sintering tunnel kilns are directly connected to the outside world. Although this facilitates feeding and discharging, the lack of corresponding plugging components at both ends will cause a large amount of heat to leak directly to the outside, resulting in high heat loss and unfavorable energy conservation. In view of this, we proposed a continuous sintering tunnel kiln for electrode materials. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 4 The utility model provides a technical solution: a continuous sintering tunnel kiln for electrode materials, comprising a tunnel kiln main body 1, wherein both ends of the tunnel kiln main body 1 are provided with a blocking assembly 2, the blocking assembly 2 comprising a guide rail frame 20 fixedly mounted on the side surface of the end portion of the tunnel kiln main body 1, and a chute 201 is provided on the left and right side plates of the guide rail frame 20, a vertical frame 23 is fixedly mounted on the top surface of the guide rail frame 20, a top plate 231 is fixedly mounted on the top plate of the vertical frame 23, a hydraulic cylinder 24 is fixedly mounted on the top plate 231, a blocking plate 25 is provided on the telescopic shaft of the hydraulic cylinder 24, the blocking plate 25 is located in the chute 201 and is slidably connected to the chute 201, so as to achieve the blocking operation on the end portion of the tunnel kiln main body 1 and reduce heat loss;

[0027] Specifically, a front fixing plate 21 is fixedly installed on the front side surface of the top plate of the guide rail frame 20, and a front limiting plate 22 is fixedly installed on the rear side surface of the front fixing plate 21. The blocking plate 25 passes through between the guide rail frame 20 and the front limiting plate 22 to implement a limiting operation on the blocking plate 25, so that the blocking plate 25 can slide between the guide rail frame 20 and the front limiting plate 22 more stably and smoothly.

[0028] In this embodiment, an end plate 3 is fixedly mounted on the side of the vertical frame 23 at the tail, and a plurality of fans 30 arranged at equal intervals are fixedly mounted on the end plate 3, so that the fans 30 can be used to cool the sintered material.

[0029] Specifically, the horizontal cross-section of the guide rail frame 20 is U-shaped, the front limit plate 22 is located on the front side of the top plate of the guide rail frame 20, the thickness of the blocking plate 25 is equal to the distance between the front limit plate 22 and the top rear plate of the guide rail frame 20, and the size of the blocking plate 25 is adapted to the size of the slide groove 201, so that the front and rear sides of the blocking plate 25 can be limited by using the front limit plate 22 and the top plate of the guide rail frame 20.

[0030] Furthermore, a steel plate 241 is fixedly installed at the end of the telescopic shaft of the hydraulic cylinder 24, and a rectangular plate 251 is fixedly installed on the top surface of the blocking plate 25. The rectangular plate 251 is fixedly installed on the bottom surface of the steel plate 241 by multiple fastening bolts, which facilitates fixed installation and disassembly operations.

[0031] In addition, the front side of the slide groove 201 is connected to the outside world, and the width of the blocking plate 25 is equal to the distance between the left and right slide grooves 201. After the front side fixing plate 21 and the front side limiting plate 22 are disassembled, the disassembled blocking plate 25 can be removed from the front side of the slide groove 201 for replacement.

[0032] It is worth noting that a limiting protrusion 26 is fixedly installed on the front side surface of the bottom plate body of the sealing plate 25. The thickness of the limiting protrusion 26 is 2 cm to 3.3 cm. After the limiting protrusion 26 moves upward until it rests on the bottom surface of the front fixed plate 21, it is used to limit the upward movement distance of the sealing plate 25.

[0033] It is worth noting that cross beams 27 are fixedly installed between the left and right side plates of the vertical frame 23 and the top surface of the tunnel kiln body 1, and pressure-resistant plates 28 are fixedly installed between the cross beams 27 and the side plates of the vertical frame 23; a triangle is formed between the cross beams 27, the pressure-resistant plates 28 and the side plates of the vertical frame 23, which plays a role in supporting the vertical frame 23.

[0034] When the electrode material continuous sintering tunnel kiln of the present invention is in use, the hydraulic cylinder 24 is started and made to work. When the hydraulic cylinder 24 works, the telescopic shaft on it is extended or shortened, which can drive the blocking plate 25 to move downward or upward. When the blocking plate 25 moves downward, it is blocked at the end of the tunnel kiln body 1 to reduce heat loss. When the blocking plate 25 moves upward, the blocking plate 25 no longer blocks the end of the tunnel kiln body 1, and normal material loading and unloading operations can be performed at this time. In addition, the fan 30 is connected to an external power supply and made to work. When the fan 30 works, the material that has been sintered and transported to the outside of the tunnel kiln body 1 is cooled.

[0035] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
