Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to an oil scraping mechanism for a quenching oil reaction vessel. Background Technology

[0002] Quenching oil is a process oil used as a quenching medium. The cooling capacity of oil is insufficient in the range of 550-650℃, with an average cooling rate of only 60-100℃ / s. However, in the range of 200-300℃, the slow cooling rate is very suitable for quenching. The oil is used for quenching alloy steel and small-section carbon steel, which can achieve satisfactory hardenability and hardenability, and can also prevent cracking and reduce deformation.

[0003] Because quenching oil has a certain viscosity, it tends to stick to the inner wall of the reactor body during production, which is inconvenient to clean, resulting in waste and difficulty in cleaning. CN211988551U discloses an oil scraping mechanism for a quenching oil reactor. The mechanism uses a threaded sleeve to drive a scraper to move vertically, and a rotating disk drives the threaded sleeve and scraper to rotate, thereby scraping the inner wall of the reactor body.

[0004] When scraping the quenching oil adhering to the inner wall using a scraper, the scraper surface also becomes coated with quenching oil, making it difficult to clean. Furthermore, the transmission structure is complex and prone to malfunction. Therefore, we propose an oil scraping mechanism for a quenching oil reactor. Utility Model Content

[0005] The purpose of this invention is to provide an oil scraping mechanism for a quenching oil reactor. By setting an annular ring plate inside the reactor body, with its outer ring touching the inner wall surface of the reactor body, the mechanism can be lowered by a multi-stage electric actuator. This simple structure achieves the purpose of scraping off residual quenching oil from the inner wall of the reactor body, is less prone to failure, and after the oil scraping is reset, high-pressure water can be sprayed from the nozzles on the inner ring of the ring to easily rinse the bottom surface of the ring plate, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil scraping mechanism for a quenching oil reactor, comprising a reactor body and an annular plate. A stirring rod is vertically rotatably mounted inside the reactor body, and the stirring rod is connected to a motor mounted on the top surface of the reactor body. The annular plate is vertically and vertically positioned inside the reactor body. Multiple electric actuators are vertically mounted on both sides of the reactor body's surface. The extended ends of the multiple electric actuators penetrate into the reactor body and are fixed to the surface of the annular plate. The outer ring of the annular plate is in contact with the inner wall surface of the reactor body. The inner ring of the annular plate is provided with a downwardly curved arc plate, which is connected to the annular plate as a single unit. The inner diameter of the annular plate is larger than the rotation diameter of the stirring rod. A ring tube is embedded and fixed in the inner wall of the reactor body below the annular plate. Nozzles communicating with the inner surface of the ring tube are evenly arranged on its inner surface, and the nozzles are inclined towards the bottom surfaces of the annular plate and the arc plate.

[0007] By adopting the above technical solution, after the quenching oil has finished reacting inside the reactor and is discharged through the discharge pipe, the ring plate is lowered by a multi-stage electric actuator to scrape the inner wall of the reactor, so that the quenching oil is scraped down and discharged, reducing the waste of quenching oil. Then the ring plate is raised to its original position and the quenching oil adhering to the bottom of the ring plate is rinsed with high-pressure water.

[0008] Optionally, an upper guide groove is provided on the inner wall surface of the vessel above the nozzle, and the upper guide groove is inclined upward.

[0009] By adopting the above technical solution, the upper guide groove ensures that the water sprayed from the nozzle can be smoothly sprayed onto the lower surface of the ring plate and the arc plate without obstruction.

[0010] Optionally, a lower guide groove is provided on the inner wall surface of the vessel below the nozzle, and the lower guide groove is inclined downward.

[0011] By adopting the above technical solution, the lower guide trough prevents the flushing water sprayed upward from accumulating in the trough embedded in the fixed ring pipe, thus avoiding the accumulation of flushing water.

[0012] Optionally, a water inlet pipe is connected to the side of the ring pipe, and the water inlet pipe communicates with the ring pipe and extends through to the outside of the vessel body.

[0013] By adopting the above technical solution, high-pressure flushing water is supplied to the inside of the ring pipe through the water inlet pipe.

[0014] Optionally, the end of the water inlet pipe is connected to a connector, which is connected to the water inlet pipe.

[0015] By adopting the above technical solution, the connection between the water inlet pipe and the high-pressure water supply pipe is achieved through a connector.

[0016] Optionally, a solenoid valve is installed on the water inlet pipe, and the battery valve is located on the water inlet pipe outside the vessel body.

[0017] By adopting the above technical solution, the battery valve controls the opening state of the water inlet pipe, and high-pressure clean water is introduced into the ring pipe when needed.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] 1. The technical solution of this application sets an annular plate inside the vessel body, with its outer ring touching the inner wall surface of the vessel body. It can be lowered by multi-stage electric actuators. The simple structure achieves the purpose of scraping off the residual quenching oil on the inner wall of the vessel body, which is not prone to failure. After the oil is scraped and reset, high-pressure water can be sprayed out by the nozzle of the inner ring of the ring tube to facilitate the rinsing of the bottom surface of the annular plate.

[0020] 2. The technical solution of this application is to provide an arc plate that is bent downward and integrally connected to the inner ring of the ring plate. The scraped quenching oil can be guided by the downward arc plate and fall downward to be discharged, so that the quenching oil will not overflow to the top of the ring plate, thereby reducing the contamination of the ring plate.

[0026] Please see Figure 1-3This utility model provides a technical solution: an oil scraping mechanism for a quenching oil reactor, including a reactor body 1 and an annular plate 2. The reactor body 1 has the same structure as existing reactors, with at least three support legs on its bottom outer ring to provide stable support. Both sides of the reactor body 1 are provided with feed pipes that communicate with the interior of the reactor body 1, used to connect the raw material inlet pipe, or pressure gauges and other detection devices can be installed. A stirring rod 5 is vertically rotatably installed inside the reactor body 1, and the stirring rod 5 is connected to a motor 51 installed on the surface of the reactor body 1 at the top. When the raw material is added, the motor 51 can be started to drive the stirring rod 5 to rotate and stir the raw material. An electric heater is installed at the bottom of the reactor body 1 to heat the raw material and increase the reaction rate. A discharge pipe that communicates with the interior of the reactor body 1 is connected to the middle of the bottom of the reactor body 1 and is sealed and fixed by a sealing cap. After the reaction is completed, the sealing cap can be unscrewed to allow the quenching oil to be discharged from the discharge pipe to the outside.

[0027] Unlike existing technologies, the ring plate 2 is positioned inside the vessel body 1 and can be raised and lowered. Multi-stage electric actuators 11 are vertically installed on both sides of the surface of the vessel body 1. The protruding ends of the multi-stage electric actuators 11 penetrate into the interior of the vessel body 1 and are fixed to the surface of the ring plate 2. The outer ring of the ring plate 2 is in contact with the inner wall surface of the vessel body 1. After the quenching oil is discharged, the multi-stage electric actuators 11 can be activated to lower the ring plate 2. Since the outer ring of the ring plate 2 is in contact with the inner wall surface of the vessel body 1, the quenching oil can be scraped down and discharged from the outlet.

[0028] The inner diameter of the ring plate 2 is larger than the rotation diameter of the stirring rod 5, so that when the ring plate 2 is present, the rotation of the stirring rod 5 will not be affected by the structure of the ring plate 2, and the stirring work can be carried out normally.

[0029] The inner ring of the ring plate 2 is provided with a downwardly curved arc plate 21. The arc plate 21 is connected to the ring plate 2 as an integral structure, so that the quenching oil scraped off by the ring plate 2 can be guided downward by the arc plate 21, so that the quenching oil will be guided downward after being scraped off, avoiding it from going over the area of ​​the arc plate 21 and reaching the top of the ring plate 2, thus preventing contamination of the upper surface of the ring plate 2.

[0030] To achieve cleaning after the quenching oil is scraped off the ring plate 2, a ring tube 3 is embedded and fixed in the inner wall of the vessel body 1 below the ring plate 2. The inner surface of the ring tube 3 is uniformly provided with nozzles 31 that communicate with its interior, and the nozzles 31 are tilted towards the bottom surface of the ring plate 2 and the arc plate 21. After the ring plate 2 scrapes off the quenching oil and resets, high-pressure clean water is introduced into the ring tube 3 and sprayed upwards from the nozzles 31, which can perform high-pressure rinsing on the bottom surface of the ring plate 2 and the arc plate 21.

[0031] A water inlet pipe 4 is connected to the side of the ring pipe 3. The water inlet pipe 4 is connected to the ring pipe 3 and extends to the outside of the vessel body 1. A connector 42 is connected to the end of the water inlet pipe 4. The connector 42 is connected to the water inlet pipe 4, which can connect the water inlet pipe 4 to the high-pressure water supply pipe through the connector 42. A solenoid valve 41 is installed on the water inlet pipe 4. The solenoid valve is located on the water inlet pipe 4 outside the vessel body 1. When the solenoid valve 41 is opened, high-pressure clean water can enter the ring pipe 3.

[0032] An upper guide groove 12 is provided on the inner wall surface of the vessel body 1 above the nozzle 31. The upper guide groove 12 is inclined upward, so that the sprayed high-pressure water will not be blocked and will be sprayed smoothly to the bottom of the ring plate 2 and the arc plate 21. A lower guide groove 13 is provided on the inner wall surface of the vessel body 1 below the nozzle 31. The lower guide groove 13 is inclined downward, so that the water after cleaning will not accumulate in the groove embedded in the fixed ring pipe 3.

[0033] In use, when the raw material enters through the feed port and is reacted inside the reactor body 1 by stirring, heating, etc., and needs to be discharged, the blockage of the bottom discharge port of the reactor is released, and the quenching oil is discharged through the bottom discharge port first. Then, the multi-stage electric actuator 11 is activated to slowly drive the ring plate 2 to lower the height. The ring plate 2 is used to abut against the inner wall of the reactor body 1 to scrape off the quenching oil adhering to the inner wall of the reactor body 1. Under the guidance of the downward bending arc plate 21 of the ring plate 2, the quenching oil falls downward and can finally be discharged from the bottom discharge port. After that, the multi-stage electric actuator 11 drives the structure to reset, so that the water inlet pipe 4 is connected to the high-pressure water supply pipe through the connector 42. After the solenoid valve 41 is opened, the high-pressure clean water can enter the ring pipe 3 through the water inlet pipe 4, and then spray high-pressure water from the nozzle 31 tilted upward from the inside, and finally act on the lower surface of the ring plate 2 to rinse the bottom surface of the ring plate 2 and the surface of the arc plate 21.
