Description

Technical Field

[0001] The invention relates to the technical field of rust-proof emulsified oil preparation equipment, and in particular to a reaction kettle and a method for preparing rust-proof emulsified oil. Background Art

[0002] At present, anti-rust emulsified oil is widely used in metal processing, machinery manufacturing, steel industry and other fields. Its cooling, lubrication and anti-rust properties can provide good protection for various mechanical equipment and metal workpieces, and improve production efficiency and product quality.

[0003] The key to its preparation is to form a stable emulsified system, and the emulsifier in the raw materials plays a key role in this. The specific raw materials have base oil with good permeability, relatively viscous emulsifier, rust inhibitor and other additives. During preparation, each raw material is put into the reactor according to the ratio requirements. Through the stirring action, heating and cooling functions of the reactor, the emulsifier molecules connect the oil phase and the water phase to form tiny emulsion particles. The lipophilic group interacts with the oil phase, and the hydrophilic group combines with the water phase, so that the oil phase and the water phase can be stably mixed together to form a stable emulsified system.

[0004] However, the current reactor simply mixes the various raw materials therein. During the actual mixing process, since the base oil and emulsifier are added in sequence first, and due to the properties of the two, the emulsifier will directly settle to the lower layer of the base oil. Based on this, the current reactor cannot be used for stirring to quickly mix the emulsifier with the upper and lower layers of the base oil. In the long run, some difficult-to-clean attachments will also adhere to the bottom of the reactor. Summary of the invention

[0020] A supporting ring is arranged in the annular through groove at the bottom of the upper rotating shaft portion, and the supporting ring abuts against the bottom of the guide member to support the guide member.

[0021] As a further technical solution, the guide member is a threaded column, the scraper member is threadedly connected to the guide member, both ends of the guide member have gear parts, the two annular grooves have tooth parts, and the gear parts mesh with the tooth parts;

[0022] Wherein, after the guide member moves, it is used to drive the scraping member to move.

[0023] As a further technical solution, the scraper is annular, the stirring plate has an arc-shaped avoidance groove, the length direction of the arc-shaped avoidance groove is parallel to the length direction of the stirring plate, and after the stirring plate rotates following the upper rotating shaft, the scraper abuts against or cancels the abutment against the arc-shaped avoidance groove;

[0028] A cover shell, wherein the cover shell is arranged on the outer wall of the kettle body, and an annular heating chamber is formed between the cover shell and the outer wall of the kettle body;

[0029] The coil is arranged in the annular heating chamber, and the coil has an inner tube and an outer tube.

[0035] The working principle and beneficial effects of the present invention are:

[0036] In the present invention, the reactor is additionally provided with a spiral drainage scraper on the basis of the original simple mixing and stirring structure, and the spiral drainage scraper is arranged below the stirring plate and abutted against the bottom of the reactor body, so that the materials attached to the bottom of the reactor body can be effectively scraped off during the rotation process. In the preparation process of the rust-proof emulsified oil, some raw materials with high viscosity are easy to remain at the bottom of the reactor, and the design can minimize such residual phenomenon and ensure that the mixed materials in the reactor can be discharged as completely as possible each time the materials are discharged, so as to avoid cross contamination between materials of different batches and ensure the stability of product quality.

[0038] Specifically, the stirring plate is rectangular and has several stirring rods arranged at intervals in the vertical direction. Below the stirring plate is a spiral drainage scraper whose length is much smaller than the stirring plate. Because the stirring plate is still the main mixing function, the spiral drainage scraper at the bottom can have an upward drainage tendency for the bottom raw materials and scrape off the bottom attachments. The stirring plate and the spiral drainage scraper are welded around the rotating shaft.

[0039] The working principle of the reactor is as follows: each raw material is put into the mixing chamber according to the prescribed proportion and sequence, the external motor is started, the shaft is driven to rotate, and the stirring plate and the spiral drainage scraper are driven to circulate in the mixing chamber, and the heating and cooling steps of the preparation process are followed, which makes it easier to mix, and also helps to promote the chemical reaction between the components, and finally completes the preparation of the rust-proof emulsified oil. It should be noted that the temperature should not be too high to avoid decomposition of the additives. At the same time, the water content in the emulsified oil should be strictly controlled, because the water content has a great influence on the stability of the oil base. In addition, when the emulsified oil is diluted into an emulsion according to the concentration required for use, attention should also be paid to the emulsification technology, such as slowly adding soft water to form an oil-in-water emulsion, and then continuing to add the remaining water and stirring fully; or using a small amount of hot water or steam to fully emulsify the emulsified oil and then dilute it with cold water.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0058] Reference Figure 1 to Figure 12 A reaction kettle for preparing rust-proof emulsified oil is proposed, comprising: a kettle body 1, the kettle body 1 has a mixing chamber 101, the mixing chamber 101 has a feed port 102 and a discharge port 103; a rotating shaft 2, the rotating shaft 2 is rotatably arranged in the mixing chamber 101; a stirring plate 3 and a spiral drainage scraper 4, the stirring plate 3 and the spiral drainage scraper 4 are both arranged on the rotating shaft 2, and the stirring plate 3 is located above the spiral drainage scraper 4; wherein the spiral drainage scraper 4 has a spiral drainage surface 401, and the bottom of the spiral drainage scraper 4 is in contact with the bottom of the kettle body 1, and after the spiral drainage scraper 4 rotates with the rotating shaft 2, the spiral drainage surface 401 is used to drain the raw materials upward.

[0059] In this embodiment, Figure 1-4As shown, the reactor is provided with a spiral drainage scraper 4 on the basis of the original simple mixing and stirring structure, and is arranged below the stirring plate 3 and abutted against the bottom of the reactor body 1, so that the materials attached to the bottom of the reactor body 1 can be effectively scraped off during the rotation. In the preparation process of the anti-rust emulsified oil, some raw materials with high viscosity are easy to remain at the bottom of the reactor, and this design can minimize such residual phenomenon and ensure that the mixed materials in the reactor can be discharged as completely as possible each time the materials are discharged, so as to avoid cross contamination between materials of different batches and ensure the stability of product quality.

[0060] Furthermore, the combined design of the stirring plate 3 and the spiral drainage scraper 4 can stir and drain the material from different levels and angles under the drive of the rotating shaft 2. Specifically, the spiral drainage surface 401 of the spiral drainage scraper 4 can lift the more viscous emulsifier at the bottom upward after rotation, and then under the action of the stirring plate 3, the emulsifier and the upper and lower layers of the base oil are fully and quickly mixed, and an upward and downward circulation flow is formed in the mixing chamber 101 of the kettle body 1, ensuring that each part of the material can fully participate in the reaction and mixing process.

[0061] Specifically, the stirring plate 3 is rectangular and has a plurality of stirring rods arranged at intervals in the vertical direction. Below the stirring plate 3 is a spiral drainage scraper 4 whose length is much smaller than that of the stirring plate 3. Because the stirring plate 3 is still the main mixing plate, the spiral drainage scraper 4 at the bottom can have an upward drainage tendency for the bottom raw materials and the function of scraping off the bottom attachments, and the stirring plate 3 and the spiral drainage scraper 4 are welded around the rotating shaft 2.

[0062] The working principle of the reactor is as follows: each raw material is put into the mixing chamber 101 according to the prescribed proportion and sequence, the external motor is started, the rotating shaft 2 is driven to rotate, and the stirring plate 3 and the spiral drainage scraper 4 are driven to circulate in the mixing chamber 101, and the heating and cooling steps of the preparation process are followed, which makes it easier to mix, and also helps to promote the chemical reaction between the components, and finally completes the preparation of the rust-proof emulsified oil. It should be noted that the temperature should not be too high to avoid decomposition of the additives. At the same time, the water content in the emulsified oil should be strictly controlled, because the water content has a great influence on the stability of the oil base. In addition, when the emulsified oil is diluted into an emulsion according to the concentration required for use, attention should also be paid to the emulsification technology, such as slowly adding soft water to form an oil-in-water emulsion, and then continuing to add the remaining water and stirring fully; or using a small amount of hot water or steam to fully emulsify the emulsified oil and then dilute it with cold water.

[0063] Furthermore, the rotating shaft 2 includes: an upper rotating shaft portion 201 and a lower rotating shaft portion 202, the upper rotating shaft portion 201 and the lower rotating shaft portion 202 are rotatably connected, and the two are coaxially arranged, the stirring plate 3 is arranged on the upper rotating shaft portion 201, and the spiral drainage scraper 4 is arranged on the lower rotating shaft portion 202, and the rotation speed of the upper rotating shaft portion 201 is greater than the rotation speed of the lower rotating shaft portion 202.

[0064] In this embodiment, Figure 2-4 As shown, in order to further improve the mixing efficiency, the stirring plates 3 and the spiral drainage scrapers 4 distributed above and below are used to split the rotating shaft 2 into two parts, namely the upper rotating shaft part 201 and the lower rotating shaft part 202 rotatably connected to its bottom. The two parts are coaxial and driven by different external motors at the top and bottom of the kettle body 1 respectively.

[0065] Specifically, there is a limiting column on the top of the lower rotating shaft portion 202, and a limiting column groove corresponding to the bottom of the upper rotating shaft portion 201. The limiting column is stuck in the limiting column groove. When the two are driven by different motors, the two can achieve different rotation speeds without any impact on the internal structure; the stirring plate 3 is welded on the upper rotating shaft portion 201, and the spiral drainage scraper 4 is welded on the lower rotating shaft portion 202.

[0066] The rotation speed of the upper rotating shaft 201 is set to be greater than that of the lower rotating shaft 202. The high-speed stirring plate 3 can quickly mix the base oil circulating up and down and the various raw materials such as the emulsifier drained from the lower layer. The drainage action does not require a high speed, but only needs a certain driving effect. The high speed of the upper layer can also slowly form a trend of rapid circulation in the entire kettle body 1.

[0067] Further consideration, such as Figure 3 As shown, since both the upper and lower parts are configured with external motors, the form of the discharge port 103 needs to be adaptively adjusted to be annular. The solid part of the bottom of the kettle body 1 outside the ring can be supported by a bracket outside the kettle body 1, and the lower rotating shaft part 202, the solid part of the kettle body 1 and the external motor inside the ring can be welded with a rigid bracket for support. In addition, a well-sealed annular discharge valve can be installed corresponding to the annular discharge port 103. After the preparation is completed, the valve is opened to complete the discharge.

[0068] Furthermore, it also includes: a guide member 5, which is movably arranged relative to the upper rotating shaft portion 201 and circulates around the upper rotating shaft portion 201, and the length direction of the guide member 5 is parallel to the length direction of the stirring plate 3; a scraper 6, which is movably arranged on the guide member 5, and is used to push the guide member 5 to move after the stirring plate 3 rotates following the upper rotating shaft portion 201; wherein, after the guide member 5 moves and the scraper 6 moves, the scraper 6 is used to scrape off the attachments on the stirring plate 3.

[0069] In this embodiment, Figure 2-7As shown, since the stirring plate 3 occupies most of the space of the kettle body 1, after long-term use, some difficult-to-clean attachments will remain on it, which need to be cleaned immediately. The spiral drainage scraper 4 is short in length and its spiral drainage surface 401 has a complex shape, which makes it inconvenient to install components adapted to it for cleaning attachments. It only needs to be stopped for cleaning regularly. Therefore, the cooperation of the guide member 5 and the scraper 6 is used to scrape off the attachments on the surface of the stirring plate 3 while mixing; the guide member 5 provides a limiting guiding function for the moving scraping action of the scraper 6. On this basis, since the entire stirring plate 3 circulates around the upper rotating shaft portion 201, the guide member 5 also needs to be able to circulate around relative to the upper rotating shaft portion 201 to avoid blocking the stirring plate 3.

[0070] Specifically, after the stirring plate 3 rotates following the upper rotating shaft portion 201, the stirring plate 3 will push the guide member 5 to move, and the moving paths of the two are the same. The scraper 6 also moves along the length direction of the guide member 5 at the same time. Since the scraper 6 is in close contact with the surface of the stirring plate 3 at this time, the movement of the scraper 6 can scrape off the attachments on the stirring plate 3.

[0071] Furthermore, it also includes: two annular blocks 7, both of which are arranged on the inner wall of the kettle body 1 and are respectively located at the top and bottom of the upper rotating shaft portion 201, the two annular blocks 7 are coaxially arranged with the upper rotating shaft portion 201, and the annular blocks 7 have an annular groove 701, the two ends of the guide member 5 are respectively located in the two annular grooves 701, and the scraper 6 is located between the two annular blocks 7; a supporting ring 8, the supporting ring 8 is arranged in the annular groove 701 at the bottom of the upper rotating shaft portion 201, and the supporting ring 8 abuts against the bottom of the guide member 5 to support the guide member 5.

[0072] In this embodiment, Figure 2-8 As shown, annular blocks 7 are installed at both ends of the upper rotating shaft portion 201 in order to provide a limiting effect on the circular movement of the guide member 5 relative to the upper rotating shaft portion 201 to prevent it from shaking back and forth, making the entire structure more tight and stable. Specifically, the two ends of the guide member 5 are respectively located in the annular grooves 701 of the two annular blocks 7, so that the movement of the scraper 6 can also be stably limited in the guide member 5 between the two annular blocks 7 to prevent the two from separating.

[0073] Furthermore, since the annular block 7 is welded to the inner wall of the kettle body 1, the annular block 7 at the top of the upper rotating shaft portion 201 can be directly welded to the inner top of the kettle body 1, and for the annular block 7 coaxially arranged at the bottom of the upper rotating shaft portion 201, its outer ring needs to be fixedly connected to the inner wall of the kettle body 1 through a welded connecting rod, so that it is stably located at the connection position between the upper rotating shaft portion 201 and the lower rotating shaft portion 202, avoiding it from being suspended in the mixing chamber 101, and its inner ring can be supported by the top of the lower rotating shaft portion 202. Specifically, the inner ring is sleeved on the top of the lower rotating shaft portion 202 and is rotatably connected to it through a bearing or a swivel, and the limiting column at the top of the lower rotating shaft portion 202 passes through the inner ring, which is clamped between the upper rotating shaft portion 201 and the lower rotating shaft portion 202 for stable support.

[0074] Similarly, the guide member 5 also needs to be supported so that it can circulate around the upper rotating shaft portion 201 at a height corresponding to the upper rotating shaft portion 201 to complete the guided scraping action. Therefore, it is necessary to prevent the guide member 5 from falling directly from the annular groove 701 below. Therefore, a supporting ring 8, that is, a stepped groove form, is welded in the annular groove 701 below to support the bottom of the upper rotating shaft portion 201.

[0075] Furthermore, the guide member 5 is a threaded column, the scraper 6 is threadedly connected to the guide member 5, both ends of the guide member 5 have gear parts 501, and the two annular grooves 701 have tooth parts 702, and the gear part 501 is meshed with the tooth part 702; wherein, after the guide member 5 moves, it is used to drive the scraper 6 to move.

[0076] In this embodiment, Figure 4-8 As shown, in order to facilitate the guide member 5 to move with the stirring plate 3, after the movement, the scraper 6 can be synchronously controlled to move along the length direction of the stirring plate 3 closely attached thereto to complete the scraping action, save costs, simplify the structure, and do not install redundant power sources. Therefore, a threaded connection is used to enable the guide member 5 to rotate during the movement, so that the annular scraper 6 threadedly connected to the guide member 5 moves synchronously; in order to realize the self-rotation of the guide member 5, gear parts 501 are welded at both ends of the guide member 5, and an annular tooth part 702 is welded in the annular groove 701, and the two are meshed. Then, after the movement, due to the meshing connection relationship, the guide member 5 rotates.

[0077] Furthermore, the scraper 6 is annular, and the stirring plate 3 has an arc-shaped avoidance groove 301, and the length direction of the arc-shaped avoidance groove 301 is parallel to the length direction of the stirring plate 3. After the stirring plate 3 rotates following the upper rotating shaft portion 201, the scraper 6 abuts against or cancels the abutment against the arc-shaped avoidance groove 301; wherein the scraper 6 has a first scraper 601 and a second scraper 602, and the first scraper 601 and the second scraper 602 are respectively used to scrape off attachments on both sides of the arc-shaped avoidance groove 301.

[0078] Furthermore, arc-shaped avoidance grooves 301 are provided on both sides of the stirring plate 3 , and there are two first scrapers 601 and two second scrapers 602 , and the two first scrapers 601 are symmetrically arranged, and the two second scrapers 602 are symmetrically arranged.

[0079] In this embodiment, Figure 4-8 As shown, the annular scraper 6 is convenient to be put on the guide member 5 and connected by threads. On the other hand, after the stirring plate 3 moves, it will directly abut against the scraper 6. By pushing the scraper 6, the entire guide member 5 can be pushed. Therefore, in order to ensure the stability of the movement, an arc-shaped avoidance groove 301 is opened at the position of the stirring plate 3 corresponding to the abutment with the scraper 6. Then, after the stirring plate 3 rotates following the upper rotating shaft portion 201, the scraper 6 abuts against the arc-shaped avoidance groove 301 to push the guide member 5.

[0080] Considering further, the attachments on the stirring plate 3, on the one hand, are the attachments in the arc-shaped avoidance groove 301, which can be directly scraped off by the scraper 6 moving along the length direction of the guide member 5, and on the other hand, are the attachments on both sides of the arc-shaped avoidance groove 301. Therefore, it is necessary to weld scrapers corresponding to the positions on both sides on the scraper 6, namely the first scraper 601 and the second scraper 602. The two groups of scrapers are used to scrape off the attachments on both sides of the arc-shaped avoidance groove 301 on one side of the stirring member; since the stirring plate 3 has arc-shaped avoidance grooves 301 on both sides, that is, the rotating shaft 2 can be rotated forward and reversely, and the attachments on the front and back sides of the stirring plate 3 can be scraped off accordingly, so two groups of scrapers are required, and each type of scraper is symmetrically arranged to adapt to the scenario where the above-mentioned action is completed.

[0081] At the same time, the guide member 5 rotates. To ensure that the scraper 6 can move linearly normally without too many degrees of freedom, a small protrusion can be welded at a fixed position on the annular outer wall of the scraper 6, and a strip groove can be opened at the corresponding position of the arc-shaped avoidance groove. When the guide member 5 is pushed, the small protrusion is stuck in the strip groove to limit the rotation angle of the scraper 6, and then the guide member 5 rotates to ensure the stable movement of the scraper 6.

[0082] Furthermore, there are a plurality of stirring plates 3 and a plurality of spiral drainage scrapers 4 . The plurality of stirring plates 3 are arranged along the circumference of the upper rotating shaft portion 201 , and the plurality of spiral drainage scrapers 4 are arranged along the circumference of the lower rotating shaft portion 202 .

[0083] In this embodiment, Figure 4-8 As shown, a plurality of stirring plates 3 are welded around the upper rotating shaft portion 201, and a plurality of spiral drainage scrapers 4 are welded around the lower rotating shaft portion 202, which can better mix various raw materials in the mixing chamber 101, greatly improve the mixing efficiency, and the drainage effect of diverting the bottom raw materials to the upper layer.

[0084] Furthermore, the feed port 102 is used to introduce the emulsifier, and also includes: a cover shell 9, which is arranged on the outer wall of the kettle body 1, and an annular heating chamber 10 is formed between the cover shell 9 and the outer wall of the kettle body 1; a coil 11, which is arranged in the annular heating chamber 10, and the coil 11 has an inner tube 12 and an outer tube 13, and both ends of the inner tube 12 pass through the cover shell 9 and the kettle body 1 respectively, and both ends of the outer tube 13 pass through the cover shell 9, the inner tube 12 is used to introduce base oil, and the outer tube 13 is used to introduce circulating hot oil.

[0085] In this embodiment, Figure 2 , 9 As shown in Figure 12, during the preparation process, a base oil with good permeability and a relatively viscous emulsifier are first added in sequence, and the entire preparation process requires a certain heating environment. Therefore, the base oil with good permeability is preheated in advance and then introduced into the mixing chamber 101, and then a relatively viscous emulsifier is added from the feed port 102. By improving the pre-preparation steps, the quality of the entire prepared product is improved. Specifically, the base oil is preheated using a coil 11 composed of an inner and outer tube 13, which is welded in an annular heating chamber 10 between the cover shell 9 and the outer wall of the kettle body 1, and the inner tube 12 circulates the base oil. The outer tube 13 circulates the circulating hot oil in the additional circulation pipeline system, which greatly saves space. Due to the good permeability and fluidity of the base oil and the heating of the circulating hot oil, there will be no blockage in the inner tube 12. The base oil can be stably introduced into the bottom of the mixing chamber 101 after being heated. Then, the feed port 102 introduces various raw materials such as relatively viscous emulsifiers, rust inhibitors and other additives, and the motor is started to drive the rotating shaft 2 to complete the preparation of the rust-proof emulsified oil. Compared with the traditional method of directly feeding all raw materials into the reactor from the feed port 102, the overall preparation efficiency is greatly improved.

[0086] A method for preparing an anti-rust emulsified oil, using the above-mentioned reaction kettle for preparing an anti-rust emulsified oil, comprises the following steps:

[0087] S1, introducing base oil into the inner tube 12, and introducing circulating hot oil into the outer tube 13;

[0088] S2, adding emulsifier, rust inhibitor and additives into the feed port 102;

[0089] S3, driving the upper rotating shaft portion 201 and the lower rotating shaft portion 202 to rotate;

[0090] S4, opening the discharge port 103 to discharge the material.

[0091] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
