Description

Technical Field

[0001] The utility model relates to the technical field of triethylamine recovery equipment, in particular to a triethylamine recovery reaction kettle. Background Art

[0002] The triethylamine recovery reactor is usually used for recovering and reusing triethylamine in chemical production. In this reactor, the operation of distilling and recovering triethylamine can be carried out. The reactor usually includes a heating system, a cooling system, a recovery system and a control system to ensure that triethylamine can be effectively separated and recovered from the mixture.

[0003] The Chinese patent with publication number CN215312252U discloses a triethylamine recovery kettle, which comprises: a recovery kettle inner tank, a top seat fixedly connected to the top of the recovery kettle inner tank by bolts, and an outer sleeve detachably connected to the outside of the recovery kettle inner tank. The utility model has the following advantages: by arranging a guide spiral plate, cooling water will enter the guide spiral plate of the recovery kettle inner tank at a certain initial velocity, and flow from the guide spiral plate in a spiral shape, which can increase the contact time between the surface of the recovery kettle inner tank and the cooling water, and improve the cooling effect; by arranging a screw rod and a limiting mechanism, when it is necessary to disassemble the recovery kettle inner tank to clean the scale accumulated on the surface, the insertion rod of the limiting mechanism is separated from the insertion block, and the insertion block can be twisted and pulled out, and the top seat and the recovery kettle inner tank can be removed for cleaning, which is very convenient.

[0004] With respect to the above-mentioned related technologies, the reactor has some shortcomings. In actual use, in order to increase the contact time between the surface of the recovery reactor inner tank and the cooling water and improve the cooling effect, improvements are made by fixing a guide spiral plate on the surface of the reactor inner tank. However, this method has some problems. First, the cooling water cannot cover the connection between the guide spiral plate and the surface of the reactor inner tank, resulting in uneven cooling effect. Second, the guide spiral plate will increase the complexity of the surface structure of the reactor inner tank, which will cause great inconvenience when cleaning scale and reduce practicality. Therefore, it is necessary to provide a triethylamine recovery reactor to solve the above-mentioned technical problems. Utility Model Content

The utility model uses a shell, a recovery kettle liner, a top seat, a mounting port, a sealing ring, an annular water storage plate, a guide cover, an electric telescopic rod, a fixing block, a drain pipe, a supporting leg and a water inlet pipe in coordination. The cooling method of the reactor is to pump cooling water into the upper part of the annular water storage plate inside the shell. Since the gap between the bottom opening of the annular water storage plate and the outside of the recovery kettle liner is limited, the flow rate of the cooling water can be limited.

At the same time, the separation and merging of the recovery kettle inner tank and the outer shell are realized by mechanical drive. Compared with manual assembly and disassembly, it is safer, more convenient and more practical.

[0017] 2. The utility model realizes the detachability between the top seat and the electric telescopic rod through the coordinated use of the mounting groove, the card slot, the fixing hole, the positioning rod, the limit rod, the pull ring, the spring, the limit groove, the limit block and the mounting block. In this way, when the inner liner of the recovery kettle is damaged, the top seat can be directly disassembled and the inner liner of the recovery kettle can be replaced. The detachable structure is simple and easy to operate. There is no need to replace the entire reactor, which improves the economy of the use of the reactor. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 1-4 , an embodiment provided by the utility model:

[0028] A triethylamine recovery reactor, comprising:

[0029] The outer shell 1 has symmetrically distributed support legs 12 fixedly installed on both sides of the bottom of the outer shell 1, and a plurality of fixed blocks 9 are fixedly installed on the outer surface of the outer shell 1. An electric telescopic rod 8 is fixedly installed on the top of the fixed block 9. A top seat 3 is provided at the driving end of the electric telescopic rod 8.

A mounting opening 4 is opened at the top of the outer shell 1, and the recovery kettle liner 2 extends to the inside of the outer shell 1 through the mounting opening 4. A sealing ring 5 is bonded to the inner wall of the mounting opening 4. An annular water storage plate 6 is fixedly installed on the upper part of the inner part of the outer shell 1;

[0030] A flow guide hood 7 is fixedly installed at the bottom of the annular water storage plate 6, and the flow guide hood 7 is located outside the recovery kettle inner tank 2, a drain pipe 11 is fixedly installed on one side of the bottom of the flow guide hood 7, and one end of the drain pipe 11 passes through one side of the bottom of the inner wall of the outer shell 1 and extends to the outside of the outer shell 1, and a water inlet pipe 23 is fixedly installed on the upper side of one side of the outer shell 1.

[0031] The driving end of the electric telescopic rod 8 is fixedly installed with a mounting block 22, and a mounting groove 13 corresponding to the position and number of the mounting block 22 is opened on the outer side of the bottom of the top seat 3, and the mounting groove 13 is clamped with the mounting block 22, and a fixing hole 15 corresponding to the position and number of the mounting groove 13 is opened on the outer surface of the top seat 3, and the fixing hole 15 is communicated with the interior of the corresponding mounting groove 13, and a limiting groove 20 is opened on the upper side of the inner wall of the fixing hole 15, and a limiting rod 17 is fixedly installed inside the limiting groove 20, and a limiting block 21 is sleeved on the outer wall of the limiting rod 17, and the limiting block 21 is slidably connected with the limiting groove 20, and a spring 19 is sleeved on one side of the limiting block 21 on the outer wall of the limiting rod 17, and a positioning rod 16 is fixedly installed on the bottom of the limiting block 21, and the positioning rod 16 is slidably connected with the fixing hole 15, and a clamping groove 14 is opened on the side of the mounting block 22 close to the fixing hole 15, and the clamping groove 14 is clamped with the positioning rod 16, and a pull ring 18 is fixedly installed on one end of the positioning rod 16.

[0032] In one embodiment, a sliding hole matched with the limiting rod 17 is opened on one side of the limiting block 21, and the limiting block 21 is slidably connected with the limiting rod 17 through the sliding hole opened on one side.

[0033] In one of the preferred embodiments, the shape of the annular water storage plate 6 is funnel-shaped, and the inner diameter of the top opening of the annular water storage plate 6 is larger than the inner diameter of the bottom opening, which can limit the flow rate and direction of the cooling water.

[0034] In one embodiment, the inner diameter of the bottom opening of the annular water storage plate 6 is the same as the inner diameter of the flow guide cover 7, and the inner diameter of the flow guide cover 7 is larger than the outer diameter of the recovery kettle inner tank 2, ensuring that there is a space between the flow guide cover 7 and the recovery kettle inner tank 2 so that the cooling water can flow smoothly.

[0035] In one of the preferred embodiments, a plurality of stabilizing rods 10 are fixedly installed between the outer surface of the air deflector 7 and the inner wall of the housing 1, thereby improving the stability of the air deflector 7 during use.

[0036] The working principle of the utility model is as follows: the electrical components appearing in the present application are all connected to an external power supply and a control switch when in use, and the parts not involved in the device are the same as the prior art or can be implemented by the prior art. When the reactor is in use, cooling water is pumped into the upper part of the annular water storage plate 6 inside the shell 1 through the water inlet pipe 23 by a water pump. After the cooling water enters the upper part of the top of the annular water storage plate 6, it will flow down along the outer surface of the recovery kettle liner 2 through the annular gap between the bottom opening of the annular water storage plate 6 and the outer surface of the recovery kettle liner 2, and the guide cover 7 will The cooling water that avoids flowing outside the recovery kettle liner 2 is guided so that the cooling water can stably flow along the outer surface of the recovery kettle liner 2. Finally, the cooling water is gathered at the bottom of the guide cover 7 and discharged through the drain pipe 11 to enter the cooler for recirculation. The cooling method of the reactor is to pump the cooling water into the upper part of the annular water storage plate 6 inside the shell 1. Since the gap space between the bottom opening of the annular water storage plate 6 and the outer wall of the recovery kettle liner 2 is limited, the flow rate of the cooling water can be limited. The annular design of the annular water storage plate 6 can control the cooling water. The cooling water is guided to form a water curtain on the outer surface of the recovery kettle liner 2, so that the cooling water and the recovery kettle liner 2 are in full contact, that is, the flow rate of the cooling water is controlled, and the uniformity of the cooling of the recovery kettle liner 2 is ensured. Later, when it is necessary to clean the scale inside the guide cover 7 and the outer surface of the recovery kettle liner 2, the electric telescopic rod 8 is directly controlled by the switch to start working. The driving end of the electric telescopic rod 8 drives the top seat 3 to move through the cooperation of the mounting block 22 and the mounting groove 13, and the movement of the top seat 3 drives the recovery kettle liner 2 to move. The top seat 3 is moved upward, and the top seat 3 can directly drive the recovery kettle liner 2 to be moved out from the inside of the shell 1 through the installation port 4, so that the outer surface of the recovery kettle liner 2 and the inside of the guide cover 7 are convenient for cleaning the scale, and the cooling structure has no connection with the outer surface of the recovery kettle liner 2, so it is very simple to carry out the cleaning work of the scale on the outer surface of the recovery kettle liner 2. At the same time, the separation and merging of the recovery kettle liner 2 and the shell 1 are realized by mechanical drive. Compared with manual assembly and disassembly, it is safer, more convenient and more practical.

[0037] During the use of the reactor, the pull ring 18 can be pulled, and the movement of the pull ring 18 drives the positioning rod 16 to slide on the fixing hole 15. The movement of the positioning rod 16 will drive the limiting block 21 to slide on the outer wall of the limiting rod 17 and squeeze the spring 19. As the positioning rod 16 moves, the positioning rod 16 will be separated from the interior of the card slot 14 on the mounting block 22. After the mounting block 22 loses the card connection limit between the card slot 14 and the positioning rod 16, the mounting block 22 can be freely removed from the interior of the mounting slot 13, thereby realizing the detachability between the top seat 3 and the electric telescopic rod 8. In this way, when the recovery kettle liner 2 is damaged, the top seat 3 can be directly disassembled and the recovery kettle liner 2 can be replaced. The detachable structure is simple and easy to operate, and there is no need to replace the entire reactor, thereby improving the economy of the use of the reactor.

[0038] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
