[0022] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0023] Example 1

[0024] According to the utility model, a low-temperature rotary furnace built-in rapping device is provided. Figure 1-4 As shown, it includes: a bracket 1, a hammer rod hammer head 2, a hammering positioning iron 3, a cylinder 4, a positioning pin 5, a positioning disk 6 and a transmission pin 7 made of corrosion-resistant materials, wherein the hammer rod hammer head 2 is made of 304, and the materials of other parts are 316L. A feasible implementation method is that the bracket 1, the hammer rod hammer head 2, the hammering positioning iron 3, the cylinder 4, the positioning pin 5, the positioning disk 6 and the transmission pin 7 are all provided with a corrosion-resistant layer. The side length of the hammer rod hammer head 2 is 8-10cm, and the hammer rod hammer head 2 rotates 20-25cm from the cylinder wall. The hammer rod hammer head 2 is installed on the transmission pin 7, and the transmission pin 7 is installed at a 4cm position of the center of the positioning disk 6 (with the center of the positioning disk 6 as the starting point, at a radius of 4cm), and the transmission pin 7 is welded to the fixed disk 6 after drilling a hole (installation hole) on the positioning disk 6. The positioning plate 6 is provided with a positioning pin 5, which protrudes from the surface of the positioning plate 6. The positioning plate 6 is connected to the bracket 1, and the bracket 1 is welded to the inner wall of the cylinder 4. A hammered positioning iron 3 is welded to the inner wall of the cylinder 4, and the height of the hammered positioning iron 3 is about 20-30cm.

[0025] Working principle: the cylinder 4 drives the positioning plate 6 to rotate, and the rotation direction and rotation angle of the positioning plate 6 are consistent with the cylinder 4. The positioning pin 5 on the positioning plate 6 drives the hammer rod hammer head 2 to rotate from the lowest position to the highest position. When the hammer rod hammer head 2 rotates to the highest position, the hammer rod hammer head 2 is freed from the restraint of the transmission pin 7, and the hammer rod hammer head 2 falls downward and rotates. The potential energy will be converted into kinetic energy, and the hammer will hit the hammer positioning iron 3 welded inside the furnace shell cylinder, generating violent vibrations to make the plated ash inside the furnace cylinder 4 fall off to achieve the ash removal effect.

[0026] More specifically, after the hammer rod hammer head 2 hits the positioning iron 3, it will continue to remain at the lowest point and be in an active state until the positioning pin 5 contacts the hammer rod and drives the hammer rod hammer head 2 upward; when the hammer rod hammer head 2 is brought to the highest point by the transmission pin 5, the hammer rod hammer head 2 will rotate rapidly downward due to gravity, and the transmission pin 5 has the same rotation speed as the cylinder 4, so the two have different speeds, and the hammer rod hammer head 2 will be separated. The structure of the utility model does not need to provide additional power to the equipment, and the hammer rod hammer head rotates with the cylinder. This method is repeated during work. Every time the furnace cylinder 4 rotates one circle, the hammer head and hammer rod 2 form a hammering and dust removal, which can effectively solve the dust accumulation inside the furnace cylinder 4.

[0027] Example 2

[0028] The utility model also provides a rapping method using a low-temperature rotary furnace built-in rapping device, comprising the following specific steps:

[0029] S1, in the initial state, the hammer rod hammer head 2 is always at the lowest position under the action of gravity;

[0030] S2. During operation, the positioning plate 6 rotates with the rotation of the cylinder 4, and the positioning pin 5 drives the hammer rod hammer head 2 from the lowest position to the highest position;

[0031] S3, when the hammer rod hammer head 2 reaches the highest position, it is free from the constraint of the transmission pin 7, and the hammer rod hammer head 2 falls freely from the highest position and rotates, so that the hammer rod hammer head 2 hits the positioning iron 3;

[0032] S4, the cylinder 4 vibrates violently through the cooperation of the hammer rod hammer head 2 and the hammering positioning iron 3, and the compacted dust inside the cylinder 4 falls off.
