Description

Technical Field

[0001] The utility model relates to the technical field of fly ash granulators, in particular to a transmission box structure of a fly ash granulator. Background Art

[0002] Existing fly ash pelletizers typically include a transmission mechanism that drives the ring die body to rotate, thereby compressing and molding the fly ash entering the press box. However, traditional transmission mechanisms have several drawbacks: First, power transmission efficiency is low. Inadequate gear meshing and poor coordination between transmission components result in significant energy loss, impacting pelletizing efficiency and quality. Second, the structure is complex and difficult to maintain. Many existing designs include cumbersome connectors and fixtures, increasing manufacturing costs and making routine maintenance and component replacement difficult. Furthermore, some equipment is prone to component loosening or wear after prolonged operation, compromising system stability and reliability. Therefore, we propose a transmission box structure for a fly ash pelletizer. Utility Model Content

[0028] Through the above solution: the fixing seat 33 is fixed to the right box wall of the pressing box 2 by screws, providing a stable support for the entire transmission system, and also facilitating the adjustment and inspection of the transmission mechanism 3. This design not only reduces the cost of daily maintenance, but also improves the adaptability and flexibility of the equipment, enabling it to respond more quickly to different production needs and environmental changes.

[0029] In this embodiment, the connecting assembly 35 includes a sleeve rod 351, which is sleeved on the mounting rod 32. A mounting bracket 352 is fixedly installed on one end of the sleeve rod 351, and the end of the mounting bracket 352 away from the sleeve rod 351 is fixedly connected to the ring mold body 4 by screws; the outer surface of the mounting rod 32 is clamped with two clamping keys 36, and the two clamping keys 36 are symmetrically arranged in the upper and lower directions; the outer surface of the sleeve rod 351 is provided with two key grooves 353 used in conjunction with the clamping keys 36, and the clamping keys 36 are clamped in the key grooves 353 to fix the sleeve rod 351 on the outside of the mounting rod 32.

[0030] Through the above solution, the connection assembly 35 adopts a detachable installation method, so that the replacement or maintenance of the ring die body 4 becomes simple and quick, and can be completed without complicated disassembly and assembly steps.

[0031] In this embodiment, the transmission assembly 34 includes a fixing ring 341, which is fixedly installed on the outer surface of the sleeve rod 351. A plurality of fixing bolts 343 are inserted into the right end of the fixing ring 341, and a transmission gear 342 is fixedly installed on the left end of the fixing ring 341 through a plurality of fixing bolts 343. The transmission gear 342 is engaged with the gear on the gear shaft 31 to connect the transmission assembly 34 to the gear shaft 31; the inner surface of the fixing ring 341 is provided with an avoidance groove 344 corresponding to the position of the card key 36, and the size of the avoidance groove 344 is adapted to the size of the card key 36.

[0032] Through the above scheme: the direct engagement between the gear shaft 31 and the transmission gear 342 ensures that the power of the external motor can be accurately transmitted to the ring die body 4.

The gear on the gear shaft 31 is engaged with the transmission gear 342 in the transmission assembly 34, thereby driving the transmission gear 342 to rotate.

Since the sleeve rod 351 is provided with a keyway 353, and the surface of the mounting rod 32 is engaged There are symmetrically arranged keys 36 in the upper and lower parts. When the sleeve rod 351 rotates, the key 36 fixes the sleeve rod 351 on the mounting rod 32 in the keyway 353, thereby ensuring that the sleeve rod 351 does not move radially relative to the mounting rod 32, and only performs synchronous rotational motion to improve stability. The rotation of the sleeve rod 351 causes the mounting frame 352 fixed at one end of the sleeve rod 351 to rotate accordingly, and then the ring die body 4 connected to the mounting frame 352 by screws also starts to rotate. The ring die body 4 is located inside the pressing box 2. During its rotation, the fly ash entering the pressing box 2 can be granulated.
