Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a high-efficiency reaction kettle with a cleaning structure. Background Art

[0002] The broad understanding of the reactor is a stainless steel container for physical or chemical reactions. The structural design and parameter configuration of the container are carried out according to different process conditions. The design conditions, process, inspection, manufacturing, and acceptance must be based on relevant technical standards to achieve the heating, evaporation, cooling, and low-speed mixing reaction functions required by the process. The reactor needs to be cleaned before use, usually with clean water, but the inner wall is often adhered to attachments that are difficult to wash off directly. If not handled, it will affect the next use.

[0003] The Chinese utility model patent with the publication number CN206577749U discloses a polyamide resin processing reactor with an efficient cleaning function. The utility model can clean the inner wall of the reactor body through the design of a brush, and the upper part of the brush is set to an arc that fits the inner wall of the reactor body, increasing the contact area between the brush and the inner wall of the reactor body. The bottom and inner wall of the reactor body can be cleaned respectively by the nozzles on the first pipe and the second pipe. However, since the inside of the brush is easily filled with reactants and the lower side position cannot be directly flushed by the nozzle, it is not conducive to the cleaning of the reactor. At the same time, the brush is easily worn after being scratched by the attachments during cleaning, and the brush itself is soft in texture, which greatly reduces the cleaning function. In addition, when the reactants need to be heated, the reactants in the middle position are heated slowly, which reduces the reaction efficiency. For this reason, we propose an efficient reactor with a cleaning structure to solve the above problems. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-efficiency reaction kettle with a cleaning structure, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a high-efficiency reactor with a cleaning structure, comprising a reactor body, a stirring shaft is rotatably installed in the middle position of the reactor body, a stirring rod is fixedly sleeved on the outer periphery of the stirring shaft near the middle and lower position, a fixing rod is fixedly connected between the stirring rods near the left and right sides, a stirring sleeve is fixedly connected between the fixing rod and the stirring rod on the lower side at the ends away from each other, a stirring slide rod is slidably connected to the other end of the stirring sleeve, a pressure spring is arranged between the inside of the stirring sleeve and the stirring slide rod, a detachable sleeve is clamped on the end of the stirring slide rod away from the stirring sleeve, the stirring slide rod on the same side is fixedly connected with a J-shaped scraper through the sleeve, and the J-shaped scraper rod is tightly pressed against the inner wall of the reactor body.

[0006] Preferably, the upper end of the stirring shaft is fixedly connected with a reduction motor, and the reduction motor is fixedly installed on the upper end of the reactor body. The lower end of the stirring shaft is fixedly sleeved with an adapter, and the adapter is fixedly installed on the inner bottom of the reactor body.

[0007] Preferably, a positioning frame is fixedly connected between the left and right ends of the stirring shaft and the fixed rod at a middle position, and heat absorbing plates are provided at the front and rear ends of the positioning frame, and the ends of the heat absorbing plates away from each other are in contact with the inner wall of the reactor body.

[0008] Preferably, a plurality of groups of heat-conducting pipes are fixedly connected between the positioning frame and the heat-absorbing plate in a matrix manner.

[0009] Preferably, two groups of evenly distributed heat transfer plates are fixedly installed inside between the positioning frame and the heat absorbing plate, and the heat conducting pipes all penetrate the heat transfer plates.

[0010] Preferably, a feeding port is provided at the upper end of the reactor body near the right side, and a discharging port is provided at the middle of the lower end of the reactor body.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The J-shaped scraper is in close contact with the inner wall of the reactor body. When it is driven to rotate, it can timely and effectively prevent the inner wall from sticking to the attachments, which is convenient for subsequent washing with clean water. However, during use, it will inevitably produce a certain amount of wear. At this time, the rebound effect of the pressure spring can drive the stirring slide bar to slide to the outside of the stirring sleeve, so that the J-shaped scraper can always maintain a relatively close fit with the inner wall of the reactor body, compensating for the influence caused by wear. The structure is simple and practical, which ensures the cleaning effect of the inner wall of the reactor body and avoids affecting the next use.

[0013] 2. When heating the reactor body, the heat on the inner wall can be quickly transferred to the heat transfer plate through the heat pipe through the heat absorption plate, and then released through the heat transfer plate. The heat transfer plate can rotate synchronously driven by the positioning frame. In conjunction with the heat pipe, while achieving the purpose of stirring and mixing, the heat can be transferred to the reactants in the middle position more evenly, greatly improving the heating efficiency of the reactants and making it more efficient.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 4 As shown, a high-efficiency reactor with a cleaning structure comprises a reactor body 1, a stirring shaft 2 is rotatably installed in the middle position of the reactor body 1, a stirring rod 3 is fixedly sleeved on the outer periphery of the stirring shaft 2 near the middle and lower position, a fixing rod 4 is fixedly connected between the stirring rods 3 near the left and right sides, a stirring sleeve 5 is fixedly connected between the fixing rod 4 and the stirring rod 3 on the lower side at the ends away from each other, a stirring slide bar 6 is slidably connected to the other end of the stirring sleeve 5, a pressing spring 7 is arranged between the inside of the stirring sleeve 5 and the stirring slide bar 6, a detachable clamping sleeve 8 is clamped on the end of the stirring slide bar 6 away from the stirring sleeve 5, and the stirring slide bar 6 on the same side is fixedly connected with a J-shaped scraper 9 through the clamping sleeve 8, and the J-shaped scraper 9 is tightly pressed against the inner wall of the reactor body 1;

[0021] The stirring rod 3 is driven by the stirring shaft 2 to make the fixed rod 4 rotate synchronously. The rotation of the fixed rod 4 can drive the stirring sleeve 5 and the stirring slide bar 6 to rotate, thereby playing a role of stirring and mixing, and improving the reaction rate of the reactor body 1. At the same time, the rotation of the stirring sleeve 5 and the stirring slide bar 6 can drive the J-shaped scraper 9 to rotate, and the J-shaped scraper 9 is in close contact with the inner wall of the reactor body 1, so that the attachment on the inner wall can be avoided in time and effectively, which is convenient for subsequent washing with clean water. Furthermore, during use, the J-shaped scraper 9 will inevitably produce a certain amount of wear. At this time, the rebound effect of the pressure spring 7 can drive the stirring slide bar 6 to slide to the outside of the stirring sleeve 5, so that the J-shaped scraper 9 can always maintain a relatively close fit with the inner wall of the reactor body 1, which makes up for the influence caused by wear and ensures the cleaning effect of the inner wall of the reactor body 1 to avoid affecting the next use.

[0022] The upper end of the stirring shaft 2 is fixedly connected with a reduction motor 10, which is fixedly installed on the upper end of the reactor body 1. The lower end of the stirring shaft 2 is fixedly sleeved with an adapter 11, which is fixedly installed on the inner bottom of the reactor body 1.

[0023] By turning on the reduction motor 10, the stirring shaft 2 can be driven to rotate, thereby providing power. The adapter 11 not only ensures that the stirring shaft 2 can rotate normally, but also plays a supporting and fixing role, and will not cause any impact when unloading through the discharge port 17.

[0024] A positioning frame 12 is fixedly connected between the left and right ends of the stirring shaft 2 and the fixed rod 4 at the middle position, and heat absorbing plates 13 are arranged at the front and rear ends of the positioning frame 12. The ends of the heat absorbing plates 13 that are far away from each other are in contact with the inner wall of the reactor body 1. Multiple groups of heat conducting pipes 14 are fixedly connected between the positioning frame 12 and the heat absorbing plates 13 in a matrix manner. Two groups of evenly distributed heat transfer plates 15 are fixedly installed inside the positioning frame 12 and the heat absorbing plates 13, and the heat conducting pipes 14 all penetrate the heat transfer plates 15.

[0025] The rotation of the stirring shaft 2 can simultaneously drive the positioning frame 12 to rotate the heat absorbing plate 13, and the heat absorbing plate 13 is also in contact with the inner wall of the reactor body 1. When the reactor body 1 is heated, the heat on the inner wall can be quickly transferred to the heat transfer plate 15 through the heat pipe 14 by the heat absorbing plate 13, so as to be released through the heat transfer plate 15. The heat transfer plate 15 can rotate synchronously driven by the positioning frame 12, and cooperate with the heat pipe 14 to achieve the purpose of stirring and mixing, and at the same time, the heat can be more evenly transferred to the reactants in the middle position, thereby greatly improving the heating efficiency of the reactants and being more efficient.

[0026] A feeding port 16 is provided at the upper end of the reactor body 1 near the right side, and a discharging port 17 is provided in the middle of the lower end of the reactor body 1 for loading and unloading operations when the reactor body 1 is in use. It is worth noting that this drawing is only a schematic diagram, and the actual object shall prevail, including but not limited to structures such as observation windows, thermometers, and pressure gauges.

[0027] Working principle:

[0028] When in use, the reduction motor 10 can be turned on to drive the stirring shaft 2 to rotate, and the stirring rod 3 is driven by the stirring shaft 2 to make the fixed rod 4 rotate synchronously. The rotation of the fixed rod 4 can drive the stirring sleeve 5 and the stirring slide bar 6 to rotate, thereby playing the role of stirring and mixing, and improving the reaction rate of the reactor body 1. At the same time, the rotation of the stirring sleeve 5 and the stirring slide bar 6 can drive the J-shaped scraper 9 to rotate, and the J-shaped scraper 9 is in close contact with the inner wall of the reactor body 1, so that the attachment on the inner wall can be timely and effectively avoided, which is convenient for subsequent water washing. Furthermore, during use, the J-shaped scraper 9 will inevitably produce a certain amount of wear. At this time, the rebound effect of the pressure spring 7 can drive the stirring slide bar 6 to slide to the outside of the stirring sleeve 5, so that the J-shaped scraper 9 can be in close contact with the inner wall of the reactor body 1 The structure is simple and practical, which ensures the cleaning effect of the inner wall of the reactor body 1 and avoids affecting the next use. In addition, the rotation of the stirring shaft 2 can simultaneously drive the positioning frame 12 to rotate the heat absorbing plate 13, and the heat absorbing plate 13 is also in contact with the inner wall of the reactor body 1. When the reactor body 1 is heated, the heat on the inner wall can be quickly transferred to the heat transfer plate 15 through the heat pipe 14 through the heat absorbing plate 13, so that the heat is released through the heat transfer plate 15. The heat transfer plate 15 can rotate synchronously driven by the positioning frame 12, and cooperate with the heat pipe 14 to achieve the purpose of stirring and mixing, and at the same time, the heat can be more evenly transferred to the reactants in the middle position, which greatly improves the heating efficiency of the reactants and is more efficient.
