Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic fiber production, and particularly relates to a beating machine for mixing and stirring ceramic fibers. Background Technique

[0002] Ceramic fiber is a fibrous lightweight refractory material, which has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and resistance to mechanical vibration. Therefore, it has been widely used in industries such as machinery, metallurgy, chemical industry, petroleum, ceramics, glass, and electronics. Ceramic fiber gaskets are heat insulation devices widely used in automobile exhaust emission devices. The first step in producing ceramic fiber gaskets is to first mix and stir the vacuum-compacted bagged ceramic fibers with additives, auxiliaries, and fillers in a beating machine, and then form ceramic fiber boards through an inclined screen forming machine.

[0003] For example, the Chinese patent with the publication number CN210439050U discloses a beating machine for mixing and stirring ceramic fibers, which relates to the production and processing field of ceramic fiber gaskets, including a main body. A stirring bin, a discharging bin, and a partition are arranged in the main body. A driving motor is arranged below the main body. A stirring blade is arranged on the upper part of the output shaft of the driving motor, and a filter screen is arranged in the middle. A slag discharge port is arranged on the side of the bottom of the stirring bin, and a discharge port is arranged on the side of the bottom of the discharging bin. A water spraying pipe is arranged on the upper part of the stirring bin. The water spraying pipe is communicated with an external high-pressure water source through a water inlet pipe arranged on one side of it. Knife teeth are arranged on the side wall of the stirring bin, and a sound insulation layer is arranged on the outer surface of the main body. The utility model can solve the problems in the prior art that the inner wall of the beating machine is difficult to clean, the service life is low, the noise is large, the agglomerated ceramic fibers cannot be filtered, and the mixing and stirring effect is poor.

[0004] This patent has some disadvantages in use. For example, when the device in this patent crushes ceramic fibers, the overall effect is poor, and it cannot crush the agglomerated ceramic fibers, which will cause waste of raw materials. In addition, the overall stirring and cutting effect of the device in this patent is poor, and it takes a long time from the raw material to the original pulp during the process of processing ceramic fiber raw materials. In view of this, we propose a beating machine for mixing and stirring ceramic fibers. Summary of the Utility Model

[0042] In this embodiment, the stirring assembly includes:

[0043] A horizontal plate 20, which is fixedly installed in the upper part of the inner cavity of the pulping tank 1. A motor support 21 is fixed at the center of the upper surface of the horizontal plate 20. Fixed supports 22 fixed to the upper surface of the horizontal plate 20 are symmetrically arranged on both sides of the motor support 21. Both the motor support 21 and the fixed supports 22 have a U-shaped structure. A driving shaft 23 is rotatably connected to the lower surface of the motor support 21. Two driving wheels 24 distributed vertically are coaxially connected to the driving shaft 23. A low-speed motor 25 is fixedly installed on the upper surface of the motor support 21, and the output shaft of the low-speed motor 25 penetrates through the upper surface of the motor support 21 and extends downward to be coaxially connected to the driving shaft 23. A bearing seat 26 is fixed to the lower surface of the fixed support 22. A driven shaft 27 is coaxially connected to the rotating shaft end of the bearing seat 26. A driven wheel 28 is coaxially connected to the driven shaft 27. A belt 29 is arranged between each of the two driving wheels 24 and the corresponding driven wheels 28 on both sides. The driving wheel 24 and the corresponding driven wheel 28 are drivingly connected by the belt 29. A main stirring shaft 30 is rotatably installed at the center of the lower surface of the horizontal plate 20, and the top end of the main stirring shaft 30 is coaxially connected to the main stirring shaft 30. A spiral blade 32 is fixed to the main stirring shaft 30. Auxiliary stirring shafts 31 are symmetrically rotatably arranged on the lower surface of the horizontal plate 20, and the top ends of the auxiliary stirring shafts 31 are coaxially connected to the corresponding driven shafts 27. A plurality of groups of evenly distributed stirring rods 33 are fixed to the auxiliary stirring shafts 31. A plurality of evenly distributed second cutter teeth 34 are arranged on the stirring rods 33.

[0044] Among them, the working principle of this device is as follows:

[0045] Start the high-speed motor 15 and the stirring assembly, fill the inner cavity of the pulping tank 1 with water, and then put the ceramic fiber raw material into the top opening of the pulping tank 1;

[0046] The stirring assembly operates, starting the low-speed motor 25. The output shaft of the low-speed motor 25 rotates and drives the rotation of the main shaft 23. The two driving wheels 24 on the main shaft 23 rotate accordingly. The two driving wheels 24 drive the corresponding driven wheels 28 to rotate through two belts 29. The two driven wheels 28 drive the rotation of two corresponding driven shafts 27 respectively. During the rotation of the main shaft 23 and the driven shafts 27, the main stirring shaft 30 and the auxiliary stirring shaft 31 rotate synchronously with the main shaft 23 and the corresponding driven shafts 27 respectively. Multiple stirring rods 33 on the auxiliary stirring shaft 31 rotate and break the ceramic fiber raw materials in the pulping barrel 1. During this process, multiple second cutter teeth 34 on the stirring rods 33 further cut the ceramic fiber raw materials. The spiral blades 32 on the main stirring shaft 30 suck the input ceramic fiber raw materials downward along the axis line and throw the original pulp at a high speed in a circular motion at the lower part, forming a violent turbulent circulation. During the suction process, the tearing of the spiral blades 32 and the mutual movement of pulp flow layers at different speeds will generate a huge frictional effect, strongly defibrating and separating the ceramic fiber pulp in the wet state. During the above process, through the action of the spiral blades 32, multiple stirring rods 33 and second cutter teeth 34, the ceramic fiber pulp continuously surges and breaks in the inner cavity of the pulping barrel 1, so that the ceramic fiber raw materials form a more uniform pulp in the pulping barrel 1, solving the shortcoming that the traditional device cannot break the agglomerated ceramic fiber raw materials;

[0047] Further, when the spiral blade 32 sucks the ceramic fiber raw material downward, the raw material will be secondarily broken and ground by the pulping mechanism below. The process is as follows: The output shaft of the high-speed motor 15 rotates and drives the rotor main body 7 to rotate. The rotor main body 7 drives a plurality of rotor blades 8 and fly knives 10 on the circumferential side to rotate synchronously. When the fly knife 10 rotates, it forms a cutting mechanism similar to the scissors principle with the bottom knife 5 on the upper surface of the sieve plate 4. And when the rotor blade 8 rotates, it will generate a vortex and suck the slurry above to the upper surface of the sieve plate 4. When the fly knife 10 rotates, the first guide surface 11 and the second guide surface 12 guide the slurry into the space between the bottom knife 5 and the fly knife 10, and the slurry is ground and cut between the upper surface of the bottom knife 5 and the lower surface of the fly knife 10. After being cut, the slurry continues to move toward the upper surface of the sieve plate 4 under the action of the third guide surface 13. The slurry that reaches the passing diameter of the sieve holes 6 passes through the sieve holes 6 and enters the lower part, while the slurry that does not reach the passing diameter of the sieve holes 6 is further broken and ground. After the pulping operation of the ceramic fiber raw material is completed, the valve 18 is opened, and the ceramic fiber slurry is discharged through the discharge pipe 17. In the above process, by setting the pulping mechanism, it is driven by the high-speed motor 15, and the rotor main body 7 drives a plurality of rotor blades 8 and fly knives 10 to rotate. The bottom knife 5 and the fly knife 10 cut and grind the slurry, further improving the fineness of the ceramic fiber slurry, while reducing the time for cutting and grinding the ceramic fiber raw material, and improving the disadvantages of the traditional device having poor pulping effect and long pulping time when pulping the ceramic fiber raw material.

[0048] Example 2:

[0049] This embodiment provides a pulper for mixing and stirring ceramic fibers. In addition to including the technical solutions of the above embodiment, it also has the following technical features: A plurality of equally spaced linearly distributed first cutter teeth 9 are fixed on the upper surface of the rotor blade 8.

[0050] Among them, by setting a plurality of first cutter teeth 9, the slurry is further cut, reducing the time used for pulping the ceramic fiber raw material and improving the pulping efficiency of this device.

[0051] Example 3:

[0052] This embodiment provides a pulper for mixing and stirring ceramic fibers. In addition to including the technical solutions of the above embodiment, it also has the following technical features: The upper surface of the bottom knife 5 is parallel to the lower surface of the fly knife 10, and the distance between the upper surface of the bottom knife 5 and the lower surface of the fly knife 10 is 3 - 7 mm.

[0053] Among them, by adjusting the appropriate distance between the bottom knife 5 and the fly knife 10, the fineness of the ceramic fiber slurry is changed.

[0054] Example 4:

[0055] This embodiment provides a pulper for mixing and stirring ceramic fibers. In addition to the technical solutions of the above embodiments, it also has the following technical features. A plurality of columns of tearing mechanisms are arranged on the inner wall of the pulping barrel 1 and are evenly distributed in a circular pattern at equal intervals. Each column of tearing mechanisms is composed of a plurality of cutter teeth three 35 that are linearly and evenly distributed.

[0056] Among them, by setting a plurality of cutter teeth three 35, when the ceramic fiber raw material tumbles and rotates in the pulping barrel 1, it can be further cut, thereby improving the pulping efficiency of the device.

[0057] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and the features in the embodiments in the present application can be combined with each other. The present application is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
