Description

Technical Field

[0001] This utility model belongs to the field of sintering equipment technology, specifically relating to a silicon carbide micro powder sintering equipment. Background Technology

[0002] Silicon carbide micron powder is an inorganic non-metallic material composed of tightly bonded carbon and silicon elements, finely processed to the micron level using specialized equipment. It is green in color, has a crystalline structure, high hardness, strong cutting ability, stable chemical properties, good thermal conductivity, and a hexagonal crystal microstructure. The processing of silicon carbide micron powder requires sintering equipment for sintering. Before sintering, a filter screen is needed to remove impurities from the raw material. However, the filters in existing sintering equipment are prone to clogging during the filtration process, thus affecting the normal flow of the raw material and resulting in generally poor practical performance.

[0003] The existing patent with publication number CN222799617U discloses a fly ash ceramsite sintering furnace, which is equipped with a spiral auger, a circular plate, a U-shaped rod, and a filter screen. When conveying raw materials, the spiral auger drives the circular plate to make an eccentric motion. During the eccentric motion of the circular plate, it will transmit power with the U-shaped rod. When the circular plate squeezes the U-shaped rod, the U-shaped rod moves upward and pushes the filter screen. When the circular plate does not squeeze the U-shaped rod, the filter screen moves downward and resets. This repeated motion causes the filter screen to vibrate up and down repeatedly, improving the filtration effect and preventing the raw materials from clogging.

[0004] However, the filter screen in the above solution can only slide back and forth in the vertical direction, and the resulting vibration amplitude is relatively weak. It cannot effectively vibrate the raw materials on the surface of the filter screen, which can easily cause the raw materials to become clogged on the surface of the filter screen, thus hindering the flow of the raw materials on the filter screen. The practical effect is generally poor. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a silicon carbide micro powder sintering equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A silicon carbide micro powder sintering device includes a furnace body, a material bucket, and a conveying mechanism. Both the conveying mechanism and the material bucket are fixedly installed on the top of the furnace body. The inlet of the conveying mechanism is connected to the inside of the material bucket, and the outlet of the conveying mechanism is connected to the inside of the furnace body. Inside the material bucket, a filter screen is reciprocated and a fixed rod is fixedly installed, with the filter screen and the fixed rod engaging in collision. The material bucket is equipped with a drive mechanism that acts on the conveying mechanism and a rack that reciprocates and slides. The drive mechanism engages with the rack through a first transmission component, and the rack engages with the filter screen through a second transmission component.

[0008] Furthermore, the material conveying mechanism includes a feeding pipe, which is fixedly installed on the top of the furnace body, and a conveying auger is rotatably installed inside the feeding pipe; one end of the built-in rotating shaft of the conveying auger is rotatably connected to the inner wall of the feeding pipe, and the other end rotatably passes through the feeding pipe.

[0009] Furthermore, the driving mechanism includes a motor, a connecting plate is fixedly installed on the outer surface of the material barrel, the motor is fixedly mounted on the connecting plate, and the output shaft of the motor is fixedly connected to one end of the internal rotating shaft of the conveying auger.

[0010] Furthermore, the first transmission component includes a second pulley, and the output shaft of the motor is fixedly sleeved on the second pulley; a first pulley is rotatably arranged on the outer surface of the material barrel, and a transmission belt is sleeved between the first pulley and the second pulley; a first connecting rod is fixedly arranged on the outer surface of the first pulley; a guide block is fixedly arranged on the outer surface of the material barrel, and the guide block is in a limiting sliding fit with the rack; a second connecting rod is provided between the rack and the first connecting rod, one end of the second connecting rod is fixedly connected to the rack, and the other end is fixedly connected to the first connecting rod.

[0011] Furthermore, the second transmission component includes a connecting shaft, through which the outer surface of the material barrel is rotatably disposed, and one end of the connecting shaft extends rotatably into the material barrel and is fixedly connected to the filter screen; a gear is fixedly sleeved on the outer surface of the connecting shaft, and the rack meshes with the gear for transmission.

[0012] Furthermore, the material hopper is equipped with rotatable baffles on both sides and a collection box that is slidably positioned. The collection box corresponds to the baffle one by one, and each collection box is slidably installed below the corresponding baffle.

[0013] Furthermore, a magnet block is fixedly installed on the material barrel, and the baffle is magnetically attracted to the magnet block.

[0014] This application has the following beneficial effects:

[0015] 1. During the material conveying process, the filter screen reciprocates under the transmission of the drive components, thereby repeatedly lifting the material above the filter screen. This not only prevents impurities from clogging the filter screen but also facilitates the flow of the material, thus improving filtration and feeding efficiency. Simultaneously, the reciprocating oscillation of the filter screen also causes it to collide with the fixed rod, resulting in vibration and further preventing impurities from clogging the filter screen, thus achieving better practical results.

[0016] 2. During the cleaning process of the filter screen, as the filter screen swings back and forth and vibrates, the impurities on the filter screen will automatically be discharged into the collection box, which makes it easy to clean the filter screen and facilitates its normal use in the future, resulting in better practical effect.

[0017] 3. By setting the baffle and the arc surface inside the furnace body, not only can the oscillation of the filter screen be provided, but also the raw materials and impurities can be prevented from slipping through the gaps during the oscillation of the filter screen.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: A silicon carbide micro powder sintering equipment includes a material bucket 2, a material conveying mechanism and a furnace body 1. The material bucket 2 and the material conveying mechanism are both fixedly installed on the top of the furnace body 1. The inlet of the material conveying mechanism is fixedly connected to the inside of the material bucket 2, and the outlet of the material conveying mechanism is fixedly connected to the inside of the furnace body 1.

[0028] Inside the material hopper 2, a filter screen 17 is reciprocatingly oscillating, and a fixed rod 19 is also fixedly mounted. The filter screen 17 collides with the fixed rod 19. The material hopper 2 is equipped with both a drive mechanism acting on the conveying mechanism and a rack 12 reciprocatingly sliding. The drive mechanism is driven by the rack 12 through a first transmission component, and the rack 12 is driven by the filter screen 17 through a second transmission component. (It should be noted that there are two fixed rods 19 in this design, and the two fixed rods 19 are located at the extreme positions of the filter screen 17 swinging to both sides. When the filter screen 17 swings to the extreme position, it collides with the fixed rod 19, thereby generating vibration.) Figure 5 (As shown)

[0029] The material conveying mechanism includes a feeding pipe 3. The feeding pipe 3 is fixedly installed on the top of the furnace body 1. A conveying auger 15 is rotatably installed inside the feeding pipe 3. One end of the built-in rotating shaft of the conveying auger 15 is rotatably connected to the inner wall of the feeding pipe 3 through a bearing. The other end of the built-in rotating shaft of the conveying auger 15 rotatably passes through the feeding pipe 3.

[0030] The drive mechanism includes a motor 6, a connecting plate 7 is fixedly installed on the outer surface of the material barrel 2, the motor 6 is fixedly installed on the connecting plate 7, and the output shaft of the motor 6 is fixedly connected to one end of the built-in rotating shaft of the conveying auger 15.

[0031] The first transmission component includes a second pulley 16, and the output shaft of the motor 6 is fixedly sleeved on the second pulley 16. A first pulley 9 is rotatably mounted on the outer surface of the material bucket 2, and a transmission belt 8 is sleeved between the first pulley 9 and the second pulley 16. A first connecting rod 10 is fixedly mounted on the outer surface of the first pulley 9.

[0032] The outer surface of the material bucket 2 is both vertically slidably equipped with a rack 12 and fixedly equipped with a guide block 20. A T-slot is formed on the rack 12, and the rack 12 is limited and slidably engaged with the guide block 20 through the T-slot. A second connecting rod 11 is provided between the rack 12 and the first connecting rod 10. One end of the second connecting rod 11 is rotatably connected to the rack 12, and the other end is rotatably connected to the first connecting rod 10.

[0033] The second transmission component includes a connecting shaft 18, which is rotatably installed on the outer surface of the material barrel 2. One end of the connecting shaft 18 extends rotatably into the material barrel 2 and is fixedly connected to the filter screen 17. A gear 13 is fixedly sleeved on the outer surface of the connecting shaft 18. The rack 12 meshes with the gear 13 and always remains in a meshed state.

[0034] In addition, both sides of the material bucket 2 are equipped with baffles 4 that rotate and collection boxes 5 that slide in a limited manner. The collection boxes 5 correspond one-to-one with the baffles 4, and each collection box 5 is slidably installed under the corresponding baffle 4.

[0035] The inner wall of the baffle 4 and the inner wall of the furnace body 1 at the swing position of the filter screen 17 are both arc-shaped. This not only provides a basis for the swing of the filter screen 17, but also prevents the raw materials and impurities in the raw materials from slipping out of the gaps during the swing of the filter screen 17.

[0036] Among them, a magnet block 14 is fixedly installed on the material barrel 2, and the baffle 4 is magnetically engaged with the magnet block 14. The magnet block 14 is used to adsorb and limit the baffle 4 after it is opened.

[0037] In addition, when the baffle 4 is in the closed state, a limiting component is provided at the contact point between the baffle 4 and the material barrel 2. This limiting component can be either a magnet block 14 fixedly installed on the material barrel 2 for magnetic attraction, or a rubber pad fixedly installed at the bottom of the baffle 4 for elastic compression. The limiting component only needs to be able to limit the baffle 4 in the closed state, and this solution does not impose specific limitations on it.

[0038] Working principle: When in use, put the raw material into the material bucket 2. The raw material entering the material bucket 2 will be filtered by the filter screen 17, and the filtered raw material will flow into the feeding pipe 3.

[0039] Start motor 6, and drive conveyor auger 15 to rotate through the output shaft of motor 6, thereby conveying the raw material in feed pipe 3, so that the raw material enters furnace body 1 for sintering treatment. Sintering treatment is existing technology and not the main innovation point, so it will not be described in detail here.

[0040] Meanwhile, the output shaft of motor 6 also drives the second pulley 16 to rotate. The second pulley 16 drives the first pulley 9 to rotate via the transmission belt 8. The first pulley 9 drives the first connecting rod 10 to rotate. The first connecting rod 10 drives the second connecting rod 11 to rotate, causing the rack 12 to slide back and forth under the limiting guidance of the guide block 20. The back and forth sliding of the rack 12 will drive the gear 13 to rotate back and forth, thereby driving the filter screen 17 to swing back and forth inside the material barrel 2 via the connecting shaft 18.

[0041] During the reciprocating oscillation of filter screen 17, the material above filter screen 17 is repeatedly lifted (without detaching from the material container 2), similar to stirring. This not only prevents impurities from clogging filter screen 17 but also facilitates the flow of material, thereby improving filtration and feeding efficiency. Simultaneously, when filter screen 17 reaches its extreme oscillation position, it will collide with the fixed rod 19, such as... Figure 5 As shown, this causes the filter screen 17 to vibrate, thereby further preventing impurities from clogging the filter screen 17 and achieving better practical results.

[0042] After the material has been added, i.e., when there is no material above the filter screen 17 and only impurities remain, and it is necessary to clean the impurities above the filter screen 17, open the baffle 4. After the baffle 4 is opened 90°, it will be attracted by the magnet 14, as shown in the image. Figure 5 As shown, at this time, as the filter screen 17 swings back and forth, the impurities can move to the collection boxes 5 on both sides. At the same time, the filter screen 17 will automatically vibrate when it swings to the limit position, thereby improving the discharge effect of impurities.

[0043] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
