Description

Technical Field

[0001] This utility model relates to the field of silicon carbide, and in particular to a high-efficiency cooling and separation device in silicon carbide production. Background Technology

[0002] Silicon carbide is a compound semiconductor material composed of silicon and carbon. It has very high hardness, thermal conductivity and chemical stability. It is extremely rare in nature and mainly exists in the form of the mineral moissanite. However, almost all silicon carbide used in industry is artificially synthesized.

[0003] In the silicon carbide production process, efficient cooling and separation equipment can significantly improve production efficiency and product quality.

[0004] The existing high-efficiency cooling and separation equipment in silicon carbide production has the following shortcomings: In the silicon carbide production process, the lumpy material exiting the sintering furnace is at an extremely high temperature and must be fully cooled before it can enter subsequent crushing, screening and other processes. However, existing cooling processes generally involve a high degree of manual intervention, which leads to operators being exposed to harsh environments of high temperature and high humidity for a long time, resulting in high labor intensity and low operational safety. Therefore, there is an urgent need to replace traditional manual intervention with automated and efficient cooling and separation equipment to improve production efficiency. Utility Model Content

[0005] This invention reduces the risk of burns and respiratory discomfort for operators, and solves the problems of high manual involvement and high labor intensity in traditional cooling processes, thereby addressing the issues raised in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency cooling and separation device for silicon carbide production, comprising a cooling mechanism, with a separation mechanism at the bottom of the cooling mechanism; the cooling mechanism includes a box body, a first water pump fixedly installed on the outer wall of the box body, a one-way valve fixedly connected to the top of the box body, a conveying pipe fixedly connected to the top of the one-way valve, a second water pump fixedly installed on the reverse side of the box body, a set of circular pipes penetrating through the top of the inner wall of the box body, fan-shaped wear-resistant nozzles fixedly installed at the bottom of each circular pipe, a set of rotating disks movably inserted into the inner wall of the box body, stirring rods fixedly connected to the inner wall of each rotating disk, and a servo motor fixedly installed on the front of the box body. Through the above components, a dual cooling mode of spraying and immersion is formed, and through subsequent control module linkage, manual intervention is reduced.

[0007] Preferably, an observation plate is fixedly connected to the top of the box, a feed cover is hinged to the top of the box, and a first support leg is fixedly connected to the outer wall of the box. The observation plate is made of transparent high-temperature resistant material, so that the operator can observe the cooling status and water level of the raw materials in the box in real time without opening the cover, avoiding steam leakage and heat loss caused by frequent opening of the cover.

[0008] Preferably, the top of the first water pump is fixedly connected to a first connecting pipe, the outer walls of the first and second water pumps are fixedly connected to a set of inlet pipes, the outer wall of the second water pump is fixedly connected to a second connecting pipe, the first connecting pipe is connected to the inside of the housing, and the second connecting pipe is connected to the inside of the circular pipe. The first water pump supplies water directly to the housing through the first connecting pipe to meet the water volume requirements for immersion cooling, and the second water pump delivers high-pressure water to the circular pipe through the second connecting pipe to ensure that the water flow sprayed from the fan-shaped wear-resistant nozzle has sufficient impact force.

[0009] Preferably, a set of condensers is fixedly installed on the reverse side of the housing, and a set of water outlet pipes is fixedly connected to the bottom of the condensers. The conveying pipe is connected to the inside of the condenser. After the high-temperature steam enters the condenser through the conveying pipe, it is cooled into liquid water and discharged through the water outlet pipe.

[0010] Preferably, a PLC controller is fixedly installed on one side of the front of the housing, and the output end of the servo motor is fixedly connected to one end of one of the rotating disks. Cooling parameters can be preset through the control panel on the PLC controller to realize automated control of the cooling process.

[0011] Preferably, a sealing strip is slidably connected to the inner wall of the box, a baffle is fixedly connected to the inner wall of the sealing strip, a conveying inclined plate is fixedly connected to the bottom of the inner wall of the box, and a first handle is fixedly connected to the front of the sealing strip. The sealing strip is made of high and low temperature resistant fluororubber material, fits the gap between the box and the baffle, and prevents cooling water from leaking from the baffle during the cooling process.

[0012] Preferably, a set of first connecting blocks is fixedly connected to the front of the box body. A first limiting plate is slidably connected to the inner wall of the first connecting block. The outer wall of the first limiting plate is slidably connected to the inner wall of the first handle. The first limiting plate can be inserted into the first handle and the first connecting block to lock the position of the baffle. During the cooling process, the baffle is locked to prevent the baffle from sliding accidentally due to equipment vibration or water flow impact, and to avoid safety accidents caused by cooling water leakage or premature material drop. When unloading, the baffle can be slid by simply pulling out the first limiting plate, which is convenient to operate.

The outer threads of the bolts penetrate the sealing rings and the inner wall of the housing. The sealing rings are made of oil- and water-resistant rubber material, which fits the gap between the drain pipes and the housing to prevent sewage leakage. The bolt connection method facilitates the disassembly and cleaning of the drain pipes and avoids the filter screens from being clogged by dust after long-term use, thus affecting the drainage efficiency.

[0014] Preferably, the separation mechanism includes a separation box, a set of vibrating motors fixedly installed on the outer wall of the separation box, a set of baffles fixedly connected to the outer wall of the separation box, a sieve plate fixedly connected to the inner wall of the separation box, a discharge port opened on the reverse side of the separation box at the position of the sieve plate, a collection box slidably connected to the inner wall of the separation box, a second handle fixedly connected to the front of the collection box, and a second support leg fixedly connected to the bottom of the separation box. The bottom of the second support leg is fixedly connected to an anti-slip pad. The vibrating motor drives the separation box to vibrate, causing the raw materials on the sieve plate to vibrate and be screened. Qualified blocky raw materials slide out of the discharge port along the sieve plate, while fine fragments and dust fall into the collection box.

[0015] Preferably, a set of second connecting blocks is fixedly connected to the front of the separation box, a second limiting plate is slidably connected to the inner wall of the second connecting block, the outer wall of the second limiting plate is slidably connected to the inner wall of the second handle, and the second limiting plate is inserted into the second handle and the second connecting block to lock the position of the collection box.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the first water pump works with the tank to achieve immersion cooling. The second water pump, the round pipe and the fan-shaped wear-resistant nozzle form a top spraying system, forming an immersion and spraying mode. This can quickly break the vapor film on the surface of the high-temperature raw materials. Combined with the rotating disk and stirring rod driven by the servo motor to turn the raw materials, the cooling dead zone is avoided and the time required for cooling is shortened. The top one-way valve is linked with the condenser to collect and condense the high-temperature steam in a directional manner. This not only prevents the explosion caused by the sudden pressure rise, but also recovers the condensate to achieve water resource recycling, reduces the diffusion of steam and dust in the workshop, reduces the risk of burns and respiratory discomfort for operators, and solves the pain points of high manual participation and high labor intensity in traditional cooling processes.

[0017] 2. In this utility model, the separation box is driven by a vibrating motor to vibrate the screen plate, which can quickly separate the cooled blocky raw materials from the fine fragments. The qualified raw materials enter the next process from the discharge port, while the fragments fall into the collection box for recycling. At the same time, the sealing strip of the box body and the sealing ring of the drain pipe ensure the sealing of the equipment and prevent cooling water leakage. The conveying inclined plate and the sliding baffle facilitate quick unloading. The first limiting plate and the second limiting plate can lock the position of key components to prevent the equipment from accidentally sliding out due to vibration. The overall structure takes into account automation and durability, which not only improves production efficiency but also extends the service life of the equipment and reduces maintenance costs and material loss.

[0025] like Figure 2 As shown, a set of condensers 115 are fixedly installed on the reverse side of the housing 101. A set of water outlet pipes 118 are fixedly connected to the bottom of the condensers 115. The conveying pipe 114 is connected to the inside of the condensers 115. After the high-temperature steam enters the condensers 115 through the conveying pipe 114, it is cooled into liquid water and discharged through the water outlet pipe 118.

[0026] like Figure 2 and Figure 5 As shown, a PLC controller 108 is fixedly installed on one side of the front of the housing 101.

The sealing rings 126 are made of oil- and water-resistant rubber material and fit the gap between the drain pipes 128 and the housing 101 to prevent sewage leakage. The bolt connection method facilitates the disassembly and cleaning of the drain pipes 128 and avoids the filter screen from being blocked by dust after long-term use, which affects the drainage efficiency.

[0030] like Figure 7 As shown, the separation mechanism 2 includes a separation box 201. A set of vibration motors 204 are fixedly installed on the outer wall of the separation box 201. A set of baffles 203 are fixedly connected to the outer wall of the separation box 201. A sieve plate 202 is fixedly connected to the inner wall of the separation box 201. A discharge port 211 is opened on the back of the separation box 201 at the position of the sieve plate 202. A collection box 210 is slidably connected to the inner wall of the separation box 201. A second handle 207 is fixedly connected to the front of the collection box 210. A second support leg 209 is fixedly connected to the bottom of the separation box 201. An anti-slip pad 205 is fixedly connected to the bottom of the second support leg 209. The vibration motors 204 drive the separation box 201 to vibrate, causing the raw materials on the sieve plate 202 to vibrate and be screened. Qualified blocky raw materials slide out of the discharge port 211 along the sieve plate 202, while fine fragments and dust fall into the collection box 210.

[0031] like Figure 7 and Figure 8 As shown, a set of second connecting blocks 206 are fixedly connected to the front of the separation box 201. A second limiting plate 208 is slidably connected to the inner wall of the second connecting block 206. The outer wall of the second limiting plate 208 is slidably connected to the inner wall of the second handle 207. The second limiting plate 208 is inserted into the second handle 207 and the second connecting block 206 to lock the position of the collection box 210.

[0032] The operating method and working principle of this device are as follows: First, the operator opens the feed cover 112 and pours the raw material into the box 101. At this time, the first water pump 109 is started to supply water into the box 101 through the first connecting pipe 110. The water volume is controlled so that water only remains at the bottom (submerging about 1 / 3 of the raw material), without complete immersion. At the same time, the second water pump 117 is started. After drawing water through the water inlet pipe 107, it delivers low-pressure, low-flow cooling water to the circular pipe 119 through the second connecting pipe 116. Then, the raw material is sprayed from the top by the evenly distributed fan-shaped wear-resistant nozzles 120 at the bottom of the circular pipe 119, using low-pressure, low-flow... The design effectively prevents the rapid vaporization of high-temperature raw materials upon contact with water, reducing the risk of steam explosion. The internal state is then monitored in real-time via a transparent high-temperature resistant observation plate 111. After a certain period of spraying, the raw material temperature decreases, and the PLC controller 108 automatically adjusts the first water pump 109 to increase the water supply. Water is slowly injected into the tank 101 through the first connecting pipe 110 until the raw material is completely submerged. During the water injection process, the servo motor 102 is activated, and its output drives the rotating disk 121 to rotate, which in turn drives the stirring rod 124 to agitate the soaking raw material, preventing material accumulation and the formation of cooling dead zones. Throughout the cooling process, the one-way valve 113 remains open. High-temperature steam, carried by the hot air flow, enters the delivery pipe 114 through the one-way valve 113 and is guided to the condenser 115. In the condenser 115, the steam is cooled and converted into liquid water. The condensate is discharged through the outlet pipe 118 and can be recycled for subsequent cooling cycles. When the raw material temperature drops to the temperature required for subsequent processes, the first water pump 109, the second water pump 117, and the servo motor 102 are shut off. Subsequently, the drain valve 129 is activated to drain the cooling water from the housing 101, and the first limiting plate 103 is slowly pulled out using the first handle 104. The dynamic sealing strip 122 and the baffle 130 connected thereto allow the cooled raw material to slide smoothly into the separation box 201 of the lower separation mechanism 2 under the guidance of the conveying inclined plate 123, completing the automatic unloading. Then, the vibration motor 204 is started, driving the separation box 201 to vibrate as a whole. The screen plate 202 installed on its inner wall vibrates synchronously, dynamically screening the incoming cooled raw material. Blocky silicon carbide that meets the particle size requirements slides along the screen plate 202 to the discharge port 211 and enters the subsequent crushing process, while fine fragments and dust fall through the screen plate 202 into the collection box 210 that is slidably connected below.

[0033] The PLC controller 108, servo motor 102, first water pump 109, check valve 113, condenser 115, second water pump 117, drain valve 129, and vibration motor 204 used in this application are all common equipment on the market and are well known to those skilled in the art. In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. Regarding their settings, installation, and electrical connection methods, those skilled in the art can debug and operate them according to the corresponding product instruction manuals, so they will not be described in detail here.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
