[0004] The centrifugal fan used in the production of calcium-zinc composite stabilizer is inconvenient to disassemble and assemble, which affects the installation efficiency. Accidental contact can cause the fan body to deviate in angle. Therefore, we propose a centrifugal ventilation device for stabilizer preparation to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a centrifugal ventilation device for the preparation of stabilizers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal ventilation device for stabilizer preparation, comprising a fixed frame and a fan body, wherein a rotating mechanism is connected to the bottom of the fan body, the rotating mechanism being used to support the fan body to rotate and adjust the angle, the rotating mechanism including a rotating seat disposed at the bottom of the fan body, the bottom of the rotating seat being rotatably engaged with the top of a support seat, the support seat being provided with a toothed seat, a locking block for limiting the rotation of the toothed seat being movablely engaged within the toothed seat, a sliding rod for pulling the locking block and the toothed seat being connected to the top of the locking block, the top of the sliding rod being movablely passing through a spring for pushing the locking block into the toothed seat and the rotating seat, and a fixing mechanism being provided on the outer wall of the support seat.

[0007] Preferably, the fixing mechanism is used to fix the support base to the fixing frame.

[0008] Preferably, the fixing mechanism includes a fixing plate disposed on the outer wall of the support base, the bolt threaded through the fixing plate and the fixing frame and used to fix the fixing plate on the fixing frame, and the bottom of the fixing plate is provided with a rubber pad.

[0009] Preferably, the support base is a cylindrical structure, and the toothed seat is an annular toothed seat fixed to the top of the support base, the diameter of the toothed seat being smaller than the diameter of the support base.

[0010] Preferably, the rotating seat is a concave cylindrical structure, and the bottom groove of the rotating seat is used to support the rotating seat to rotate on the gear seat. The bottom groove of the rotating seat is an annular structure.

[0011] Preferably, the sum of the heights of the locking block and the toothed seat is less than the height of the groove in the rotating seat, and the top of the spring is connected to the top of the groove in the rotating seat.

[0012] Preferably, the fixing plate has multiple sets evenly distributed on the outer wall of the support base, the bolts are hand-tightening screws, and the rubber pads are made of soft rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Rotate the bolts to connect the bolt thread to the fixing bracket and the fixing plate, and fix the fixing plate on the fixing bracket. The rubber pad prevents the fixing plate from directly contacting the fixing bracket, reducing vibration and noise. The fan body is installed on the fixing bracket by rotating the mechanism, which makes it easy to disassemble and assemble the fan body and improves the installation efficiency.

[0015] 2. Pull the sliding rod upwards. The sliding rod pulls the locking block upwards, separating it from the toothed seat. The locking block moves upwards, compressing the spring. Then, it pushes the rotating seat to rotate on the support seat. The fan body then rotates with the rotating seat. When the angle of the fan body is suitable for operation, stop pushing the rotating seat and release the sliding rod. The spring returns to its original state, pushing the locking block downwards to engage with the tooth groove of the toothed seat. This restricts the rotation of the rotating seat on the support seat, thereby restricting the adjustment angle of the fan body. This allows for stable adjustment of the fan body angle and prevents accidental displacement of the fan body angle. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 A centrifugal ventilation device for stabilizer preparation includes a fixed frame 1 and a fan body 2. A fixing mechanism 4 is provided on the outer wall of a support base 31. The fixing mechanism 4 is used to fix the support base 31 to the fixed frame 1. The fixing mechanism 4 includes a fixing plate 41 provided on the outer wall of the support base 31. A bolt 42 is threaded through the fixing plate 41 and the fixed frame 1 and is used to fix the fixing plate 41 to the fixed frame 1. A rubber pad 43 is provided at the bottom of the fixing plate 41. The fixing plate 41 has multiple sets evenly distributed on the outer wall of the support base 31. The bolt 42 is a hand-tightening screw, and the rubber pad 43 is made of soft rubber.

[0022] Rotate bolt 42, which connects the fixing bracket 1 and the fixing plate 41 with threads, and fix the fixing plate 41 on the fixing bracket 1. Rubber pad 43 prevents the fixing plate 41 from directly contacting the fixing bracket 1, reducing vibration and noise. The fan body 2 is installed on the fixing bracket 1 by rotating mechanism 3, which makes it easy to disassemble and assemble the fan body 2 and improves installation efficiency.

[0023] A rotating mechanism 3 is connected to the bottom of the fan body 2. The rotating mechanism 3 is used to support the rotation of the fan body 2 and adjust the angle. The rotating mechanism 3 includes a rotating seat 32 located at the bottom of the fan body 2. The bottom of the rotating seat 32 is rotatably engaged with the top of the support seat 31. The support seat 31 is provided with a toothed seat 33. A locking block 34 for limiting the rotation of the toothed seat 33 is movable and engaged within the toothed seat 33. A sliding rod 35 for pulling the locking block 34 and the toothed seat 33 apart is connected to the top of the locking block 34. The top of the sliding rod 35 moves through to push the locking block 34. 4. The spring 36 and the rotating seat 32 are inserted into the tooth seat 33. The support seat 31 is a cylindrical structure. The tooth seat 33 is an annular tooth seat fixed on the top of the support seat 31. The diameter of the tooth seat 33 is smaller than the diameter of the support seat 31. The rotating seat 32 is a concave cylindrical structure. The groove at the bottom of the rotating seat 32 is used to support the rotating seat 32 to rotate on the tooth seat 33. The groove at the bottom of the rotating seat 32 is an annular structure. The total height of the locking block 34 and the tooth seat 33 is less than the height of the groove of the rotating seat 32. The top of the spring 36 is connected to the top of the groove of the rotating seat 32.

[0024] Pull the sliding rod 35 upwards. The sliding rod 35 pulls the locking block 34 upwards and separates it from the toothed seat 33. The locking block 34 moves upwards and compresses the spring 36. Then, it pushes the rotating seat 32 to rotate on the support seat 31. The fan body 2 then rotates with the rotating seat 32. When the angle of the fan body 2 is suitable for operation, stop pushing the rotating seat 32 and release the sliding rod 35. The spring 36 returns to its original state, and the locking block 34 moves downwards and engages in the tooth groove of the toothed seat 33. This restricts the rotation of the rotating seat 32 on the support seat 31, thereby restricting the rotation angle adjustment of the fan body 2. This allows for stable adjustment of the angle of the fan body 2 and avoids accidental contact that could cause the angle of the fan body 2 to deviate.

[0025] Working principle: This utility model uses a rotating bolt 42, which is threadedly connected to the fixing frame 1 and the fixing plate 41, fixing the fixing plate 41 to the fixing frame 1. The rubber pad 43 prevents the fixing plate 41 from directly contacting the fixing frame 1, reducing vibration and noise. The fan body 2 is installed on the fixing frame 1 through the rotating mechanism 3, making it easy to disassemble and assemble the fan body 2 and improving installation efficiency. Pulling the sliding rod 35 upwards pulls the locking block 34 upwards and separates it from the toothed seat 33. The locking block 34 moves upwards and compresses the spring 36, then pushes the rotating seat 32 to rotate on the support seat 31. The fan body 2 then rotates with the rotating seat 32. When the angle of the fan body 2 is suitable for operation, the rotating seat 32 is stopped and the sliding rod 35 is released. The spring 36 returns to its original state, and the locking block 34 is pushed downwards and locked into the tooth groove of the toothed seat 33, restricting the rotation of the rotating seat 32 on the support seat 31, thereby restricting the rotation adjustment angle of the fan body 2, so that the angle of the fan body 2 can be stably adjusted and the angle deviation of the fan body 2 can be avoided by accidental contact.

[0026] The blower body 2 and the gear seat 33 are existing technologies and will not be described in detail here.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
