Description

Technical Field

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

[0002] Ceramic-based composites are a type of composite material that is composed of ceramics as the matrix and various fibers. The ceramic matrix can be high-temperature structural ceramics such as silicon nitride and silicon carbide. The use of high-strength and high-elasticity fibers combined with the matrix is ​​an effective way to improve the toughness and reliability of ceramics.

[0003] A Chinese patent discloses a raw material mixing device for preparing functional ceramics, with the publication number CN216260311U, including a material receiving box, a handle, a bracket, a first fixed block, a shell, a baffle, a rotating shaft, a support column, a second fixed block, a motor, a water inlet pipe, a rotating sheet, a scraper block and a feed hopper. The first fixed block is fixed with a bracket at intervals on one side of the circumference, and the shell is fixed to the inner circumference of the first fixed block. The material receiving box is placed between the three brackets, and the handle is fixed to the outer side of the material receiving box. In this solution, the lid is pulled upward to swing open the feed hopper, and the two raw materials to be mixed are poured from the feed hopper into the shell, and the motor is started. The motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the rotating sheet to rotate. The rotation of the rotating sheet will stir the two raw materials and water. In this way, there is no need to stir and mix the raw materials manually, which is convenient to operate and labor-saving.

[0004] However, it still has the following disadvantages: the device starts the motor to start the rotating blade to mix the raw materials, but the space above the baffle is small, resulting in a dead angle for mixing, 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. To this end, we proposed a raw material mixing device for ceramic fiber composite material production to solve this problem. Summary of the invention

The outer surface of the limit plate is fixedly connected to the outer surface of the mounting rod. A through groove is provided on the top surface of the limit plate. The outer surface of the return frame is slidably connected to the inner wall of the through groove. A slide rail is provided on the inner wall of the tank body.

[0007] 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 outer surface of the bottom end of the motor output shaft rotates through the top surface of the tank body and extends to the inner side of the tank body through a bearing, the bottom surface of the motor output shaft is fixedly connected with a rotating rod, the cross-section of the rotating rod is square, the cross-section of the rotating rod is square, the top surface of the mounting rod is provided with a slide groove, the outer surface of the bottom end of the rotating rod extends to the inside of the slide groove and is slidably connected to the inner wall of the slide groove, the outer surface of the support rod is fixedly connected to the outer surface of the stirring plate, by arranging a motor, a rotating rod, a mounting rod, a first sliding rod, a support rod and a stirring plate, starting the motor, the motor, and the motor output shaft drive the rotating rod and the mounting rod to rotate, so that the stirring plate stirs and mixes the raw materials inside the tank body.

[0008] A further improvement of the technical solution of the present invention is that: the end face of the first sliding rod away from the mounting rod is fixedly connected to a baffle, the bottom surface of the counterweight block is fixedly connected to a first elastic rod, and the outer surface of the first elastic rod is fixedly connected to the bottom surface of the baffle. By arranging the counterweight block and the first elastic rod, the rotation speed of the motor is increased, so that the counterweight block slides along the outer surface of the first sliding rod due to the increase of the centrifugal force, and the counterweight block 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, the stirring position of the stirring plate is changed, and the stirring effect of the device is improved.

[0009] A further improvement of the technical solution of the present invention is that: the bottom end of the mounting rod extends to the inner side of the discharging funnel, the outer surface of the bottom end of the mounting rod is fixedly connected to a second sliding rod, the flip plate is slidably sleeved on the outer surface of the second sliding rod, the outer surface of the mounting rod is fixedly connected to a second elastic rod, the bottom surface of the second elastic rod is fixedly connected to the top surface of the flip plate, the bottom surface of the flip plate is in squeeze contact with the inner wall of the discharging funnel, and by arranging the second sliding rod, the second elastic rod and the flip plate, the elastic force of the second elastic member is utilized to make the bottom surface of the flip plate in squeeze contact with the inner wall of the discharging funnel, so that the flip plate stirs the raw materials settled to the bottom of the discharging funnel, thereby further improving the stirring effect of the device, and at the same time, when the tank body is cleaned, the flip plate is utilized to scrape the inner wall of the discharging funnel to improve the cleaning effect.

[0010] The outer surface of the return frame is fixedly connected to the outer surface of the limit rod, and the outer surface of the limit rod slides through the inner wall of the limit plate and extends to the outside of the limit plate, and the outer surface of the limit rod away from the return frame extends to the inside of the slide rail and is slidably connected to the inner wall of the slide rail, and the outer surface of the return frame is fixedly connected to the outer surface of the second spring, and the second spring is fixedly connected to the inner wall of the limit plate away from the return frame. The return frame is limited by the elastic force of the second spring, so that the outer surface of the limit rod maintains stable sliding along the inner wall of the slide rail. When the outer surface of the limit 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, thereby expanding the stirring range of the stirring plate, and the mounting rod drives the second sliding rod and the flip plate to move up and down, and the elastic force of the second elastic rod is used to push the flip plate to move, so that the bottom surface of the flip plate is always in extrusion contact with the inner wall of the discharging funnel, while expanding the flipping range of the flip plate, further improving the stirring effect and cleaning effect of the flip plate.

By arranging the fixing rod, the swing rod and the connecting rod, and by controlling the rotation speed of the motor, the centrifugal force on the counterweight block is changed, so that the outer surface of the limit rod is moved out of the slide rail, so that the mounting rod and the stirring plate no longer move up and down with the rotation of the motor.

[0012] A further improvement of the technical solution of the present invention is that when the outer surface of the stirring plate contacts the inner wall of the tank body, the swing arm collides with the inner wall of the return frame, so that when the motor rotates at a faster speed, the outer surface of the stirring plate contacts the inner wall of the tank body, and at the same time, the counterweight block drives the connecting rod and the swing arm to move, so that the swing arm pushes the return frame to move, so that the outer surface of the limit rod moves out of the slide rail, thereby avoiding the motor rotating at a faster speed, resulting in greater wear between the outer surface of the limit rod and the inner wall of the slide rail, and generating more heat.

[0013] A further improvement of the technical solution of the present invention is that: a first spring is fixedly connected to the inner wall of the mounting rod, and the top 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 limit rod moves out of the slide rail, the elastic force of the first spring is utilized to make the outer surface of the limit rod between the highest point and the lowest point of the slide rail. When the motor speed decreases, it is convenient for the outer surface of the limit rod away from the return frame to re-adapt to the inner wall of the slide rail.

[0014] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art: 1.

When the motor speed is increased, the counterweight is subjected to centrifugal forces of different magnitudes, so that the counterweight slides along the outer surface of the first sliding rod, drives the support rod and the stirring plate to move, changes the distance between the stirring plate and the inner wall of the tank body, changes the stirring position of the stirring plate, and improves the stirring effect of the device. 2. The present invention provides a raw material stirring device for producing ceramic fiber composite materials, which is provided with a second sliding rod, a second elastic rod and a flip plate, and utilizes the elastic force of the second elastic member to make the bottom surface of the flip plate squeeze and contact with the inner wall of the discharge funnel, so that the flip plate stirs the raw materials settled at the bottom of the discharge funnel, further improving the stirring effect of the device; 3. The present invention provides a raw material stirring device for producing ceramic fiber composite materials. By setting a limit rod, a first spring, a limit plate, a return frame, a second spring and a slide rail, when the motor drives the rotating rod and the mounting rod to rotate, the outer surface of the limit rod slides along the inner wall of the slide rail, so that the limit rod drives the mounting rod to move up and down, and the stirring plate moves up and down, thereby expanding the stirring range of the stirring plate and the stirring effect of the device. At the same time, the mounting rod drives the second sliding rod and the flip plate to move up and down, and the elastic force of the second elastic rod is used to push the flip plate to move, so that the bottom surface of the flip plate is always in compression contact with the inner wall of the discharge funnel, while expanding the flipping range of the flip plate, further improving the stirring effect of the device; 4. The present invention provides a raw material stirring device for the production of ceramic fiber composite materials. By arranging a fixed rod, a swing rod and a connecting rod, the motor speed is further increased when the inner wall of the tank is cleaned, and the centrifugal force exerted on the counterweight block is increased, so that the outer surface of the stirring plate contacts the inner wall of the tank. At the same time, the counterweight block drives the connecting rod and the swing rod to move, so that the swing rod pushes the return frame to move, so that the outer surface of the limit rod moves out of the slide rail, thereby avoiding the motor speed being too fast, resulting in greater wear between the outer surface of the limit rod and the inner wall of the slide rail, and generating more heat.
