Description

Technical Field

[0001] The present invention relates to the technical field of ceramic raw material mixing, and particularly relates to a raw material stirring device for the production of ceramic fiber composite materials. Background Art

[0002] Ceramic matrix composites are a class of composite materials composed of a ceramic matrix and various fibers. The ceramic matrix can be a high-temperature structural ceramic such as silicon nitride or silicon carbide. Using high-strength and high-elasticity fibers to be combined with the matrix is an effective method to improve the toughness and reliability of ceramics.

[0003] A Chinese patent discloses a raw material mixing device for the preparation of functional ceramics, with the publication number CN216260311U, which includes a material receiving box, a handle, a bracket, a first fixing block, a housing, a baffle, a rotating shaft, a support column, a second fixing block, a motor, a water inlet pipe, a rotating blade, a scraping block, and a feed hopper. The first fixing block is circumferentially and spacedly fixedly connected with a bracket on one side, and the housing is fixedly connected to the inner circumference of the first fixing block. The material receiving box is placed between the three brackets, and the handle is fixedly connected to the outer side of the material receiving box. In this solution, the lid is pulled upwards to swing open the feed hopper, and the two raw materials to be mixed are poured into the housing from the feed hopper. The motor is started, and the motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the rotating blade to rotate, and the rotation of the rotating blade will stir the two raw materials and water. In this way, there is no need for manual stirring and mixing of the raw materials, and the operation is convenient and labor-saving.

[0004] However, it still has the following disadvantages: The device starts the motor to start the rotation of the rotating blade to mix the raw materials. However, the space above the baffle is small, resulting in a stirring dead angle, and the position of the rotating blade cannot be adjusted. The device has a poor disturbance effect on the dead angle area, resulting in a poor raw material mixing effect. For this reason, we propose a raw material stirring device for the production of ceramic fiber composite materials to solve this problem. Summary of the Invention

[0005] The present invention provides a raw material stirring device for the production of ceramic fiber composite materials to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A raw material stirring device for the production of ceramic fiber composite materials includes a tank body. The bottom surface of the tank body is fixedly and through-connected with a discharge funnel. The bottom surface of the discharge funnel is fixedly connected with a mounting bracket. The left end surface of the tank body is fixedly and through-connected with a feed pipe. A mixing mechanism is arranged inside the tank body, and the mixing mechanism includes a power part;

[0008] The power unit includes a motor, a mounting rod, a stirring plate, a first sliding rod, a counterweight, a support rod, and a turning plate. The outer surface of the first sliding rod is fixedly connected to the outer surface of the mounting rod. The counterweight is slidably sleeved on the outer surface of the first sliding rod. The outer surface of the support rod is fixedly connected to the outer surface of the counterweight;

[0009] An adjusting unit is provided above the stirring plate;

[0010] The adjusting unit includes a limiting plate, a U-shaped frame, and a limiting rod. The outer surface of the limiting plate is fixedly connected to the outer surface of the mounting rod. A through groove is formed in the top surface of the limiting plate. The outer surface of the U-shaped frame is slidably connected to the inner wall of the through groove. A slide rail is formed on the inner wall of the tank body.

[0011] A further improvement of the technical solution of the present invention is that the bottom surface of the motor is fixedly connected to the top surface of the tank body. The bottom end outer surface of the motor output shaft rotatably penetrates the top surface of the tank body through a bearing and extends to the inner side of the tank body. A rotating rod is fixedly connected to the bottom surface of the motor output shaft. The cross section of the rotating rod is square. The cross section of the rotating rod is square. A chute is formed in the top surface of the mounting rod. The bottom end outer surface of the rotating rod extends into the chute and is slidably connected to the inner wall of the chute. The outer surface of the support rod is fixedly connected to the outer surface of the stirring plate. By setting the motor, the rotating rod, the mounting rod, the first sliding rod, the support rod, and the stirring plate, when the motor is started, the motor output shaft drives the rotating rod and the mounting rod to rotate, so that the stirring plate stirs and mixes the raw materials inside the tank body.

[0012] A further improvement of the technical solution of the present invention is that a baffle is fixedly connected to the end surface of the first sliding rod away from the mounting rod. A first elastic rod is fixedly connected to the bottom surface of the counterweight. The outer surface of the first elastic rod is fixedly connected to the bottom surface of the baffle. By setting the counterweight and the first elastic rod, the rotation speed of the motor is increased, so that the centrifugal force received by the counterweight becomes larger, and the counterweight slides along the outer surface of the first sliding rod. The counterweight drives the support rod and the stirring plate to move, so that the distance between the stirring plate and the inner wall of the tank body is reduced, and the stirring position of the stirring plate is changed, improving the stirring effect of the device.

[0013] A further improvement of the technical solution of the present invention is that the bottom end of the mounting rod extends into the inner side of the discharge funnel. A second sliding rod is fixedly connected to the bottom end outer surface of the mounting rod. The turning plate is slidably sleeved on the outer surface of the second sliding rod. A second elastic rod is fixedly connected to the outer surface of the mounting rod. The bottom surface of the second elastic rod is fixedly connected to the top surface of the turning plate. The bottom surface of the turning plate is in pressing contact with the inner wall of the discharge funnel. By setting the second sliding rod, the second elastic rod, and the turning plate, using the elastic force of the second elastic member, the bottom surface of the turning plate is in pressing contact with the inner wall of the discharge funnel, so that the turning plate stirs the raw materials settled at the bottom inside the discharge funnel, further improving the stirring effect of the device. At the same time, when the tank body is cleaned, the turning plate is used to scrape the inner wall of the discharge funnel, improving the cleaning effect.

[0014] A further improvement of the technical solution of the present invention lies in that: the outer surface of the U-shaped frame is fixedly connected to the outer surface of the limiting rod, the outer surface of the limiting rod slidably penetrates through the inner wall of the limiting plate and extends to the outside of the limiting plate, the outer surface of the limiting rod on the side away from the U-shaped frame extends into the inside of the slide rail and is slidably connected to the inner wall of the slide rail, the outer surface of the U-shaped frame is fixedly connected with a second spring, and one end of the second spring away from the U-shaped frame is fixedly connected to the inner wall of the limiting plate. The elastic force of the second spring is used to limit the U-shaped frame, so that the outer surface of the limiting rod maintains stable sliding along the inner wall of the slide rail. When the outer surface of the limiting rod moves on the inner wall of the slide rail, it drives the mounting rod to move up and down, so that the stirring plate moves up and down, expanding the stirring range of the stirring plate. The mounting rod drives the second slide rod and the turning plate to move up and down. The elastic force of the second elastic rod is used to push the turning plate to move, so that while the bottom surface of the turning plate is always in pressing contact with the inner wall of the discharge funnel, the turning range of the turning plate is expanded, further improving the stirring effect and cleaning effect of the turning plate.

[0015] A further improvement of the technical solution of the present invention lies in that: a fixed rod is fixedly connected to the outer surface of the mounting rod, a swing rod is hinged to one end of the fixed rod away from the mounting rod, the bottom end of the swing rod penetrates through the inside of the U-shaped frame and extends above the U-shaped frame, a connecting rod is hinged to the bottom surface of the swing rod, and the bottom surface of the connecting rod is hinged to the top surface of the counterweight block. By setting the fixed rod, the swing rod and the connecting rod, by controlling the rotation speed of the motor, the centrifugal force received by the counterweight block is changed, so that the outer surface of the limiting rod moves out of the slide rail, and the mounting rod and the stirring plate no longer move up and down with the rotation of the motor.

[0016] A further improvement of the technical solution of the present invention lies in that: when the outer surface of the stirring plate contacts the inner wall of the tank body, the swing rod collides with the inner wall of the U-shaped frame, so that when the rotation speed of the motor is relatively fast, the outer surface of the stirring plate contacts the inner wall of the tank body. At the same time, the counterweight block drives the connecting rod and the swing rod to move, so that the swing rod pushes the U-shaped frame to move, and the outer surface of the limiting rod moves out of the slide rail, avoiding the relatively large wear between the outer surface of the limiting rod and the inner wall of the slide rail and generating more heat due to the relatively fast rotation speed of the motor.

[0017] A further improvement of the technical solution of the present invention lies in that: a first spring is fixedly connected to the inner wall of the mounting rod, and the top end of the first spring is fixedly connected to the bottom surface of the rotating rod. By setting the first spring, when the outer surface of the limiting rod moves out of the slide rail, the elastic force of the first spring is used to make the outer surface of the limiting rod between the highest point and the lowest point of the slide rail. When the rotation speed of the motor decreases, it is convenient for the outer surface of the limiting rod on the side away from the U-shaped frame to be re-adapted to the inner wall of the slide rail.

[0018] Due to the adoption of the above technical solution, the technical progress achieved by the present invention compared with the prior art is:

By setting a rotating rod, a motor, a mounting rod, a stirring plate, a counterweight, a first elastic rod, a first sliding rod, a support rod and a baffle, starting the motor, the output shaft of the motor drives the rotating rod and the mounting rod to rotate, so that the stirring plate stirs and mixes the raw materials inside the tank body. By increasing the rotation speed of the motor, the counterweight slides along the outer surface of the first sliding rod due to different centrifugal forces, driving the support rod and the stirring plate to move, changing the distance between the stirring plate and the inner wall of the tank body, changing the stirring position of the stirring plate, and improving the stirring effect of the device;

[0020] 2. The present invention provides a raw material stirring device for the production of ceramic fiber composite materials. By setting a second sliding rod, a second elastic rod and a turning plate, using the elastic force of the second elastic member, the bottom surface of the turning plate is in pressing contact with the inner wall of the discharge funnel, so that the turning plate stirs the raw materials settled at the bottom inside the discharge funnel, further improving the stirring effect of the device;

[0021] 3. The present invention provides a raw material stirring device for the production of ceramic fiber composite materials. By setting a limiting rod, a first spring, a limiting plate, a return-shaped frame, a second spring and a slide rail, during the process of the motor driving the rotating rod and the mounting rod to rotate, the outer surface of the limiting rod slides along the inner wall of the slide rail, so that the limiting rod drives the mounting rod to move up and down, making the stirring plate move up and down, expanding the stirring range of the stirring plate, expanding the stirring effect of the device. At the same time, the mounting rod drives the second sliding rod and the turning plate to move up and down.

[0034] The cross-section of the rotating rod 3201 is square. The top surface of the mounting rod 3203 is provided with a chute. The bottom end outer surface of the rotating rod 3201 extends into the chute and is slidably connected to the inner wall of the chute. The outer surface of the support rod 3209 is fixedly connected to the outer surface of the stirring plate 3204. By setting the rotating rod 3201, the motor 3202, the mounting rod 3203, the stirring plate 3204, the counterweight 3205, the first elastic rod 3207, the first sliding rod 3208, the support rod 3209, and the baffle 3212, when the motor 3202 is started, the output shaft of the motor 3202 drives the rotating rod 3201 and the mounting rod 3203 to rotate, so that the stirring plate 3204 stirs and mixes the raw materials inside the tank body 2. By increasing the rotation speed of the motor 3202, the counterweight 3205 is subjected to different centrifugal forces, so that the counterweight 3205 slides along the outer surface of the first sliding rod 3208, driving the support rod 3209 and the stirring plate 3204 to move, changing the distance between the stirring plate 3204 and the inner wall of the tank body 2, changing the stirring position of the stirring plate 3204, and improving the stirring effect of the device;

By setting the second sliding rod 3210, the second elastic rod 3211, and the turning plate 3206, using the elastic force of the second elastic member 3211, the bottom surface of the turning plate 3206 is in pressing contact with the inner wall of the discharge funnel 4, so that the turning plate 3206 stirs the raw materials settled at the bottom inside the discharge funnel, further improving the stirring effect of the device; Embodiment 2

[0036] As Figures 1-7 shown, on the basis of the first embodiment, an adjusting part 31 is arranged above the stirring plate 3204;

[0037] The adjusting part 31 includes a limiting plate 3105, a return frame 3106 and a limiting rod 3101. The outer surface of the limiting plate 3105 is fixedly connected to the outer surface of the mounting rod 3203. A through groove is formed on the top surface of the limiting plate 3105. The outer surface of the return frame 3106 is slidably connected to the inner wall of the through groove. A slide rail 3109 is formed on the inner wall of the tank body 2. The outer surface of the return frame 3106 is fixedly connected to the outer surface of the limiting rod 3101. The outer surface of the limiting rod 3101 slidably penetrates through the inner wall of the limiting plate 3105 and extends to the outside of the limiting plate 3105. The outer surface of the limiting rod 3101 on the side away from the return frame 3106 extends into the slide rail 3109 and is slidably connected to the inner wall of the slide rail 3109;

[0038] A second spring 3107 is fixedly connected to the outer surface of the return frame 3106. One end of the second spring 3107 away from the return frame 3106 is fixedly connected to the inner wall of the limiting plate 3105. By arranging the limiting rod 3101, the first spring 3104, the limiting plate 3105, the return frame 3106, the second spring 3107 and the slide rail 3109, during the process of the motor 3202 driving the rotating rod 3201 and the mounting rod 3203 to rotate, the outer surface of the limiting rod 3101 slides along the inner wall of the slide rail 3109, so that the limiting rod 3101 drives the mounting rod 3203 to move up and down, and the stirring plate 3204 moves up and down, expanding the stirring range of the stirring plate 3204 and the stirring effect of the device. At the same time, the mounting rod 3203 drives the second sliding rod 3210 and the turning plate 3206 to move up and down. By using the elastic force of the second elastic rod 3211 to push the turning plate 3206 to move, while the bottom surface of the turning plate 3206 is always in pressing contact with the inner wall of the discharge funnel 4, the turning range of the turning plate 3206 is expanded, further improving the stirring effect of the device; Embodiment Three

[0039] As Figures 1-7 shown, on the basis of the second embodiment, a fixed rod 3102 is fixedly connected to the outer surface of the mounting rod 3203. One end of the fixed rod 3102 away from the mounting rod 3203 is hinged with a swing rod 3103. The bottom end of the swing rod 3103 penetrates through the inside of the return frame 3106 and extends above the return frame 3106. A connecting rod 3108 is hinged to the bottom surface of the swing rod 3103. The bottom surface of the connecting rod 3108 is hinged to the top surface of the counterweight 3205;

[0040] When the outer surface of the stirring plate 3204 contacts the inner wall of the tank body 2, the swinging rod 3103 impacts the inner wall of the U-shaped frame 3106. A first spring 3104 is fixedly connected to the inner wall of the mounting rod 3203, and the top end of the first spring 3104 is fixedly connected to the bottom surface of the rotating rod 3201. By setting the fixed rod 3102, the swinging rod 3103 and the connecting rod 3108, when cleaning the inner wall of the tank body 2, the rotation speed of the motor 3202 is further increased, the centrifugal force received by the counterweight 3205 is enlarged, so that the outer surface of the stirring plate 3204 contacts the inner wall of the tank body 2. At the same time, the counterweight 3205 drives the connecting rod 3108 and the swinging rod 3103 to move, so that the swinging rod 3103 pushes the U-shaped frame 3106 to move, and the outer surface of the limiting rod 3101 moves out of the slide rail 3109, avoiding the large wear between the outer surface of the limiting rod 3101 and the inner wall of the slide rail 3109 and generating more heat due to the relatively fast rotation speed of the motor 3202.

[0041] Next, the working principle of the raw material stirring device for producing the ceramic fiber composite material will be specifically described.

[0042] During use, the motor 3202 is started. The output shaft of the motor 3202 drives the rotating rod 3201 to rotate and the mounting rod 3203 to rotate. The mounting rod 3203 drives the stirring plate 3204 to rotate. By using the elastic force of the second elastic member 3211, the bottom surface of the turning plate 3206 is in extrusion contact with the inner wall of the discharge funnel 4. The mounting rod 3203 drives the turning plate 3206 to stir the raw materials settled at the bottom inside the discharge funnel. During the process of the motor 3202 driving the rotating rod 3201 and the mounting rod 3203 to rotate, the outer surface of the limiting rod 3101 slides along the inner wall of the slide rail 3109, so that the limiting rod 3101 drives the mounting rod 3203 to move up and down, and the stirring plate 3204 moves up and down, expanding the stirring range of the stirring plate 3204. At the same time, the mounting rod 3203 drives the second sliding rod 3210 and the turning plate 3206 to move up and down. By using the elastic force of the second elastic rod 3211 to push the turning plate 3206 to move, the bottom surface of the turning plate 3206 is always in extrusion contact with the inner wall of the discharge funnel 4; the rotation speed of the motor 3202 is increased, so that the centrifugal force received by the counterweight 3205 becomes larger, and the counterweight 3205 slides along the outer surface of the first sliding rod 3208, driving the support rod 3209 and the stirring plate 3204 to move, so that the distance between the stirring plate 3204 and the tank body 2 becomes smaller, changing the stirring position of the stirring plate 3204; when cleaning the inner wall of the tank body 2, the rotation speed of the motor 3202 is further increased, the centrifugal force received by the counterweight 3205 is enlarged, so that the outer surface of the stirring plate 3204 contacts the inner wall of the tank body 2. At the same time, the counterweight 3205 drives the connecting rod 3108 to move, causing the top of the swinging rod 3103 to swing. The swinging rod 3103 pushes the U-shaped frame 3106 to move, and the outer surface of the limiting rod 3101 moves out of the slide rail 3109, so that the mounting rod 3203 no longer moves up and down with the rotation of the motor 3202.

[0043] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present invention are within the protection scope of the present invention.
