Description

TECHNICAL FIELD

[0001] The utility model relates to airflow mill technical field, concretely is a kind of fixing mechanism of airflow mill. BACKGROUND

[0002] Airflow mill is a kind of equipment using high-speed airflow to grind and crush material. It uses compressed air to accelerate into supersonic airflow through Laval nozzle and then injects into crushing area, so that material is fluidized under the action of airflow, i.e. material particles are suspended, boiled and collide with each other in fluidized bed formed by airflow expansion. Such collision and friction lead to gradual crushing of material particles.

[0003] For example, Chinese patent application No. 202322682720.8 discloses a feeding device for airflow mill, which includes an airflow mill body and a feed hopper. The feed hopper is arranged at the top of the airflow mill body. The top of both sides of the airflow mill body is fixedly connected with a protrusion. The side of the feed hopper close to the protrusion is fixedly connected with a positioning block. The side of the protrusion close to the positioning block is provided with a positioning groove matched with the positioning block. The inner cavity of the positioning block is provided with a movable slot. The fixing mechanism, fixing groove and control mechanism are used in cooperation. The pressing rod is pressed, and the pressing rod pushes the control plate to move. The control plate pushes the fixing block into the inner cavity of the movable slot through the control block, and squeezes the spring. This solves the problem that the existing part of the airflow mill installs the feed hopper through bolts, and the bolts are prone to slippage during installation. Moreover, there are many installed bolts, which affects the installation efficiency of the feed hopper.

[0004] During the use of the airflow mill, although it is stably supported on the ground through the support frame at the bottom, it still shakes and vibrates during full-power operation. These problems not only cause uneven crushing of the material, but also increase the friction between mechanical parts, which seriously affects the crushing quality and shortens the service life of the parts.

[0005] Therefore, it is necessary to design and reform the fixing mechanism of the airflow mill to effectively prevent the phenomenon of unstable fixing of the support frame. UTILITY MODEL CONTENT

The surface of the screw 2 is threadedly connected to the inner wall of the movable frame. The screw 2 can fix the position of the support leg after it is flipped outward.

The inner walls of the limiting holes 12 on the surface of limiting blocks 211 and the limiting holes 23 on the top of the movable frame 7 are threaded together. There is a screw 14, which can be threaded to the inner wall of the limiting hole 13 at the bottom of the movable frame 7 and the limiting hole 12 on the surface of the limiting block 10 after the movable frame 7 is flipped outward, thereby fixing the position of the movable frame 7 when it is flipped outward. The surface of the support leg 9 is provided with a through hole 15, and the inner wall of the through hole 15 is threaded to a screw 16. The surface of the screw 16 is threaded to the inner wall of the movable frame 7, and the screw 16 can fix the position of the support leg 9 after it is flipped outward.

[0024] As a technical optimization of this utility model, the design of the limiting mechanism ensures that the movable frame 7 and the support leg 9 can be stably stopped in the required position, avoiding equipment damage or safety accidents caused by shaking or movement. At the same time, the threaded connection makes the fixation more secure and reliable.

[0025] refer to Figure 2 Each connecting block 5 has a support rod 17 fixedly connected to its bottom, and the bottom of the support rod 17 is fixedly connected to the top of the support frame 3.

[0026] As a technical optimization of this utility model, by setting the support rod 17, not only is support provided for the fixing mechanism, but the motor 2 and the air mill 1 are also tightly connected together by the connecting block 5 and the support block 6, thereby enhancing the structural strength of the entire equipment.

[0027] refer to Figure 2 A reinforcing cylinder 18 is fixedly connected to the surface of the support rod 17, and the bottom of the reinforcing cylinder 18 is fixedly connected to the top of the support frame 3.

[0028] As a technical optimization of this utility model, the reinforcement cylinder 18 further enhances the supporting capacity of the support rod 17, making the entire fixing mechanism more stable and reliable. Simultaneously, the bottom of the reinforcement cylinder 18 is fixedly connected to the top of the support frame 3, which also helps to distribute stress.

[0029] refer to Figure 2 The inner side of each support rod 17 is fixedly connected to a stabilizing plate 19, and the inner side of the stabilizing plate 19 is fixedly connected to the surface of the air jet mill 1.

[0030] As a technical optimization of this utility model, by setting a stabilizing plate 19, not only is the stability of the air mill 1 enhanced, but also, by being fixedly connected between the inner side of the support rod 17 and the surface of the air mill 1, damage to the equipment caused by the vibration generated during the operation of the air mill 1 is avoided.

[0031] refer to Figure 2 Each of the support legs 9 is fixedly connected to a foot 20 at its bottom, and the bottom of the foot 20 has elasticity and anti-slip capability.

[0032] As a technical optimization of this utility model, by setting the support legs 20, the device can adapt to different ground conditions, improving the adaptability and stability of the equipment. At the same time, the elasticity and anti-slip capability of the bottom of the support legs 20 also ensure the safety and stability of the equipment during operation.

[0033] The working principle and usage of this utility model are as follows: This airflow mill 1 fixing device mainly includes an airflow mill 1, a motor 2, a support frame 3, and a fixing mechanism. The top of the airflow mill 1 is connected to the motor 2 through a transmission device to ensure the normal operation of the airflow mill 1. A stable support frame 3 is installed at the bottom of the airflow mill 1 to provide support for the entire device. The fixing mechanism is the core part of this device. It includes a fixing ring 4 fixedly connected to the surface of the motor 2, and connecting blocks 5 are evenly distributed around the fixing ring 4. Support blocks 6 are fixed to the bottom of each of these connecting blocks 5, and a movable frame 7 is movably connected to the inner wall of the support block 6. A connecting rod 8 is fixed to the inner side of the movable frame 7, and a support leg 9 is movably connected to the surface of the connecting rod 8. In addition, a limit mechanism is provided around the airflow mill 1 to ensure that the movable frame 7 and the support leg 9 can be stably stopped in the required position. When it is necessary to fix the running position of the airflow mill 1, it can be achieved by operating the fixing mechanism. First, by loosening screws 14 and 16 in the limiting mechanism, the movable frame 7 and support leg 9 can be flipped outwards and moved. Then, screw 14 is used to fix the movable frame 7 in the desired position. Simultaneously, the support leg 9 can also be flipped outwards and fixed in the appropriate position by screw 16. This allows the motor 2 and the middle section of the airflow mill 1 to be stressed, thereby stabilizing the operation of the airflow mill 1. During the adjustment process, the reinforcing cylinder 18 and the stabilizing plate 19 play a crucial role. The reinforcing cylinder 18 is fixedly connected to the surface of the support rod 17, providing additional support and stability to the entire fixing mechanism. The stabilizing plate 19 is fixedly connected between the inner side of the support rod 17 and the surface of the airflow mill 1, further enhancing the stability of the airflow mill 1. This avoids the uneven grinding and reduced service life caused by shaking and vibration during the operation of the existing airflow mill 1, giving it the advantage of stable operation.

[0034] In summary, when this utility model is used, the running position of the air jet mill 1 can be fixed under the action of the fixing mechanism and the limiting mechanism, which avoids the uneven crushing and reduced service life caused by shaking and vibration during the operation of the existing air jet mill 1, thus giving it the advantage of stable operation and solving its problem of unstable operation.
