A boiling drying granulator

Abstract

The utility model discloses a fluidized bed drying granulator, which belongs to the technical field of fluidized bed drying granulators. Raw materials are put into a crushing box, and the crushing teeth are cross teeth. Through mutual meshing and biting, the agglomerated raw materials can be crushed into powder, and then transported through a feed pipe. During the transportation process, part of the raw materials will adhere to the inner wall of the feed pipe. Through the vibration of the vibration motor, the adhered raw materials are shaken off and fall into the feed pipe to continue to flow. When arriving at the connection with the granulator body, the electric cylinder drives the breaking wheel to break the raw materials again to prevent the raw materials from agglomerating during transportation and affecting the granulation quality. The raw materials fall into the granulator body and are filtered through the sieve plate for the final process. When the internal granulation is completed, if internal cleaning is required, the motor is rotated to drive the rotating rod, and the rotating rod drives the sieve plate to flip and clean the sieve plate.

DETAILED DESCRIPTION

[0022] In the following description, numerous specific details are given in order to provide a more thorough understanding of the present invention.

[0023] It will be apparent, however, to one skilled in the art that the present invention may be practiced without one or more of these details.

[0024] In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0025] like Figure 1-Figure 5 As shown, a boiling drying granulator consists of a transmission box 1, a fixed frame 2, a crushing device 3, a crushing box 4, a feeding pipe 5, a vibration motor 6, a discharge valve 7, an electric cylinder 8, a support column 9, a granulator body 10, a fixed seat 11, a sleeve 12, a shock-absorbing spring 13, a sleeve seat 14, crushing teeth 15, a scattering wheel 16, a screen plate 17, a rotating rod 18, and a rotating motor 19.

[0026] like Figure 1-Figure 5 As shown, the raw materials are placed in a crushing box 4, and a crushing motor outside the crushing box 4 drives the crushing teeth 15 to rotate. In order to achieve a better crushing effect, the crushing teeth 15 are arranged as a cross-tooth structure, which mesh with each other, thereby generating a greater bite force, a larger contact surface with the material, and a higher crushing efficiency. The crushed agglomerates are in powder form, which is convenient for subsequent granulation and molding.

[0027] A bellows coupling is connected to the connection between the feed pipe 5 and the crushing box 4. The bellows coupling makes the connection between the two more stable and can also compensate for the corner position. The bellows coupling is made of stainless steel and is more durable and corrosion-resistant.

[0028] A sleeve 14 is sleeved on the feed pipe 5, and a vibration motor 6 is installed on the sleeve 14. The vibration force generated by the vibration motor 6 drives the sleeve 14 to vibrate, so that the raw materials adhering to the inner wall of the feed pipe 5 can be shaken off to prevent the internal raw materials from clogging the feed pipe 5. At the same time, it can effectively prevent the raw materials from adhering to and agglomerating for a long time, causing pollution and deterioration, affecting the quality of the raw materials entering the feed pipe 5 later.

[0029] A sleeve 12 is installed at the bottom of the sleeve 14, and the sleeve 12 is fixedly connected to the support column 9. A shock-absorbing spring 13 is installed at the connection. When the vibration motor 6 vibrates, the shock-absorbing spring 13 is used for external shock absorption to prevent the sleeve 14 from falling off due to long-term use.

[0030] The discharge valve 7 is installed on the side of the sleeve 14, which can control the amount of raw materials entering the granulator body 10 each time, and is convenient for maintaining the granulation quality.

[0031] An electric cylinder 8 is installed on the side of the discharge valve 7, and the output end of the electric cylinder 8 extends into the interior of the feed pipe 5, where the feed pipe 5 is one end connected to the granulator body 10; and a breaking wheel 16 is installed inside it, which is transmission-connected to the output end of the electric cylinder 8. When the material is stored in the feed pipe 5 for a long time, the raw materials will have lumps of different sizes. When passing through the breaking wheel 16, the lumps can be broken up by the breaking wheel 16 to ensure that the raw materials falling into the granulator body 10 are in powder form, which is convenient for subsequent granulation and ensures the granulation quality.

[0032] A sieve plate 17 is arranged inside the granulator body 10 . The raw materials falling into the granulator body 10 pass through the sieve plate 17 , while part of the raw materials will fall outside the gap. The sieve plate 17 can be turned over by the rotation of the rotating rod 18 .

[0033] When the whole equipment needs to be cleaned, the sieve plate 17 can be turned over to clean it more thoroughly and prevent residues from being left on the surface.

[0034] The working principle of this utility is as follows:

[0035] The raw materials are put into the crushing box 4. The crushing teeth 15 are cross teeth. Through mutual meshing and biting, the agglomerated raw materials can be broken into powder, and then transported through the feed pipe 5. During the transportation process, some raw materials will adhere to the inner wall of the feed pipe 5. The vibrating motor 6 vibrates to shake off the adhered raw materials and fall into the feed pipe 5 to continue flowing. When it arrives at the connection with the granulator body 10, the electric cylinder 8 drives the breaking wheel 16 to break the raw materials again to prevent the raw materials from agglomerating during transportation and affecting the granulation quality. The raw materials fall into the granulator body 10 and pass through the sieve plate 17 for the final process filtration. When the internal granulation is completed, if internal cleaning is required, the rotating motor 19 drives the rotating rod 18, and the rotating rod 18 drives the sieve plate 17 to flip and clean the sieve plate 17.

[0036] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
