[0033] Example 1

[0034] refer to Figures 1-3 The L-shaped base for the fly ash granulator includes a support base 1, which includes a first part 11 supporting the spiral compression part and a second part 12 supporting the drive part.

[0035] The width of the second part 12 is greater than the width of the first part 11, so that the support base 1 is in an "L" shape;

[0036] The first part 11 has a first thread array for fixing the spiral compression part, the first thread array including at least four first thread holes 15;

[0037] The second part 12 has at least two sets of second thread arrays for fixing the drive motor. The second thread array includes at least four second thread holes 16. The positions of the second thread holes 16 of the two sets of second thread arrays do not completely overlap.

[0038] The first thread array and the second thread array are staggered, so that the central axis of the spiral rod of the spiral compression part fixed by the first thread array is not coaxial with the central axis of the motor shaft of the drive motor fixed by the second thread array.

[0039] The above design, firstly, allows the second threaded array to be staggered from the first threaded array, thus allowing the screw rod to be staggered from the motor shaft. This staggered connection effectively increases the distance between the two, reducing the impact of vibration on the motor shaft. Secondly, the second part 12 of this invention has more than one set of second threaded arrays. The position of the drive motor can be changed or different sizes of drive motors can be fixed by selecting the appropriate second threaded array, thereby increasing the practicality of this invention. Finally, this invention optimizes the shape of the support base 1 to be "L"-shaped. This allows for the staggered position of the second threaded array from the first threaded array; it also allows for more than one set of second threaded arrays; furthermore, the area of ​​the support base 1 at the screw compression section is small, facilitating material feeding, observation, and cleaning of the screw compression section by the user.

[0040] The second part 12 also has a third threaded array for fixing the reducer. The third threaded array includes at least four third threaded holes 17, and is located between the first threaded array and the second threaded array. This invention adds a third threaded array to the base, allowing the reducer to be fixed via the third threaded array. This enables the motor shaft and the screw rod to be connected via the reducer, further reducing the impact of vibration on the motor shaft and allowing speed adjustment between the two.

[0041] A metal-rubber composite pad 2 is provided on the upper side of the support base 1, and the metal-rubber composite pad 2 is provided with a threaded through hole 21. Each of the first threaded hole 15, the second threaded hole 16, and the third threaded hole 17 is provided with a corresponding threaded through hole 21. A connecting bolt is provided in each of the first threaded hole 15, the second threaded hole 16, and the third threaded hole 17, and each connecting bolt passes through the threaded through hole 21 and is threadedly engaged with the first threaded hole 15, the second threaded hole 16, or the third threaded hole 17. The metal-rubber composite pad 2 on the upper side of the support base 1 can effectively absorb impact and vibration, reduce the vibration transmission during mechanical operation, and protect the support base 1 and its driving part and helical compression part.

[0042] The lower side of the support base 1 is provided with a portion extending outward from the side, called a lower flange 14, and at least 6 through holes for bolts are arranged on the lower flange 14. The lower flange 14 can provide an additional support surface, making the support base 1 more stable when bearing heavy loads and reducing the risk of overturning or deformation. The lower flange 14 and the provided bolt through holes facilitate quick installation and disassembly.

[0043] A pad 6 with a thickness of 10-15mm is provided below each of the perforations; the pad 6 is made of polyethylene. The polyethylene pad 6 can absorb some vibration and has high strength and good durability, thereby improving its shock absorption effect and weather resistance.

[0044] A lifting ring is provided on the upper side of the support base 1 to facilitate its movement.

[0045] In use, the support base 1 is fixed to the ground with bolts through holes with at least 6 bolts and pads 6. The support base 1 forms an L-shaped structure through the first part 11 and the second part 12, which can separate the spiral compression part and the support drive part, and avoid the vibration of the spiral compression part being directly transmitted to the drive part. A metal-rubber composite pad 2 is provided on the upper side of the support base 1. The metal-rubber composite pad 2 can effectively absorb impact and vibration, reduce the vibration transmission during mechanical operation, and protect the support base 1 and its drive part and spiral compression part. Then, the spiral compression part and drive part of the fly ash granulator are fixed with connecting bolts 3 to ensure the stable operation of the fly ash granulator.

[0046] Example 2

[0047] refer to Figure 1 and Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0048] The support base 1 includes a cover plate and side plates supporting the cover plate, the cover plate and side plates forming a hollow groove with an opening facing downwards; a threaded hole is provided on the cover plate; the connecting bolt 3 is also fitted with a connecting nut 4, the connecting nut 4 engaging with the connecting bolt 3 by threads, and the connecting nut 4 is located on the lower side of the cover plate. The cover plate has a limited thickness, and using only the threaded hole on the support base 1 would easily damage the threads. By placing the connecting nut 4 below the threaded hole, the length of the thread engaging with the connecting bolt 3 is extended. This design effectively protects the threaded hole, thereby reducing the risk of thread wear and damage, and ensuring the stability of the spiral compression part and the drive part installed on the support base 1.

[0049] A receiving seat 13 is provided below the cover plate, and the receiving seat 13 has a nut groove for accommodating the connecting nut 4; the groove is connected to the threaded hole, and the opening of the nut groove faces downward. The number of receiving seats 13 is the same as the number of threaded holes. The receiving seat 13 facilitates the fixing or replacement of the connecting nut 4, so that when the threaded hole and the thread of the connecting nut 4 are damaged, the connecting nut 4 can be replaced and continued to be used, simplifying maintenance and reducing maintenance costs.

[0050] The thickness of the metal-rubber composite pad 2 is 20-25mm; the thickness of the cover plate is 5-12mm. This ensures the stability of the support base 1 structure and the shock absorption effect of the metal-rubber composite pad 2.

[0051] The lower end cover 5 is also provided with a detachable lower end cover 5, the size of which is larger than the diameter of the connecting bolt 3 but smaller than the minimum outer diameter of the connecting nut 4. The lower end cover 5 is provided to prevent the connecting nut 4 from falling out of the downward-facing receiving seat 13.

[0052] In use, the thickness of the plate surface of the support base 1 is limited, and the threaded hole on the support base 1 alone can easily damage the thread. By placing the connecting nut 4 below the threaded hole, the length of the thread that engages with the connecting bolt 3 is extended. This design can effectively protect the threaded hole. The receiving seat 13 makes it easy to fix or replace the connecting nut 4, so that when the threaded hole and the thread of the connecting nut 4 are damaged, the connecting nut 4 can be replaced, simplifying maintenance and reducing maintenance costs.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
