[0006] To achieve the above purpose, the present utility model adopts the following technical solution: A condensation reactor includes a tank body and a stirring paddle rotatably arranged in the reaction cavity of the tank body. A cleaning liquid guiding cavity is formed at the top inside the tank body. The cleaning liquid guiding cavity is communicated with a cleaning liquid inlet pipe.

Detailed Embodiment
[0013] The following further details the present utility model through specific embodiments:
[0014] As Figure 1 and Figure 2 shown, an embodiment of the present utility model provides a condensation reactor, including a tank body 1 and a stirring paddle 2 rotatably arranged in the reaction cavity of the tank body 1. A cleaning liquid guide cavity 3 is formed at the top inside the tank body 1. The cleaning liquid guide cavity 3 is connected to a cleaning liquid inlet pipe. The cleaning liquid guide cavity 3 has a plurality of cleaning conduits 4 through a rotationally arranged conduction structure 5. The plurality of cleaning conduits 4 are annularly distributed in the reaction cavity and each cleaning conduit 4 is distributed in the axial direction of the tank body 1. The plurality of cleaning conduits 4 are all fixedly connected to the stirring paddle 2 and a number of flushing holes are evenly distributed on each cleaning conduit 4.
[0015] When the condensation reactor is being cleaned, cleaning water with a certain pressure is introduced into the cleaning liquid guide cavity 3 through the cleaning liquid inlet pipe. Then, the cleaning water is introduced into the reaction cavity from multiple cleaning conduits 4. A number of flushing holes on each cleaning conduit 4 evenly spray the cleaning water to flush the stirring paddle 2 and the inner wall of the reaction cavity. After a certain amount of cleaning water accumulates in the reaction cavity, the rotation of the stirring paddle 2 is coordinated to accelerate the cleaning, and then the cleaning water is discharged. A number of flushing holes continue to spray the cleaning water to flush the stirring paddle 2 and the inner wall of the reaction cavity, improving the cleaning effect on the reaction cavity and the stirring paddle 2. When the stirring paddle 2 rotates in the reaction cavity to stir the reaction materials in the reaction cavity, the multiple cleaning conduits 4 also rotate with the stirring paddle 2 to enhance the stirring intensity of the reaction materials, which is more conducive to the condensation reaction of the reaction materials in the reaction cavity.
[0016] In this embodiment, the number of the cleaning conduits 4 is shown as two, and can be specifically adjusted according to requirements.
[0017] Among them, a number of flushing holes are formed on each cleaning conduit 4 along the circumferential direction of the cleaning conduit 4 to form multiple groups of flushing holes, and each group of flushing holes is evenly spaced along the axial direction of the cleaning conduit 4 as a number of flushing holes, so that each cleaning conduit 4 sprays cleaning water uniformly in all directions from top to bottom, improving the flushing effect on the inner wall of the reaction cavity and the stirring paddle 2.
[0018] To better understand this solution, the following will further optimize the conduction structure 5 and other structures.
[0019] As Figure 2 shown, according to another embodiment of the present invention, the condensation reactor, wherein the conduction structure 5 includes an annular conduction hole 51 and a conduction plate 52. Among them, the annular conduction hole 51 is opened at the bottom of the cleaning liquid guide cavity 3 and communicated, and it is arranged in a ring outside the central axis of the stirring paddle 2; the conduction plate 52 is rotatably arranged at the bottom of the cleaning liquid guide cavity 3 and seals the annular conduction hole 51, and each cleaning conduit 4 is communicated with a liquid guide hole opened on the conduction plate 52.
[0020] During the rotation of the multiple cleaning conduits 4 with the stirring paddle 2, the conduction plate 52 rotates at the bottom of the cleaning liquid guide cavity 3; through the above-mentioned cooperation mode of the annular conduction hole 51, the conduction plate 52 and the liquid guide hole, the multiple cleaning conduits 4 can rotate with the stirring paddle 2, playing a stirring role in the reaction cavity for the reaction materials and the multiple cleaning conduits 4 can always remain connected with the inside of the cleaning liquid guide cavity 3, so that the cleaning water in the cleaning liquid guide cavity 3 can be introduced into each cleaning conduit 4 during cleaning, and then sprayed into the reaction cavity for flushing.
[0021] As Figure 2As shown, according to another embodiment of the present utility model, for the condensation reactor, a premixing chamber 6 is further formed at the top inside the tank body 1. The cleaning liquid guiding chamber 3 is sleeved outside the premixing chamber 6. At least one feed pipe communicating with the premixing chamber 6 is arranged at the top of the tank body 1, and a material guiding hole 7 communicating with the reaction chamber is opened at the bottom of the premixing chamber 6.
[0022] In this embodiment:
[0023] Inside the tank body 1, at the top, the tank body 1 is separated into a first cavity and a reaction chamber which are distributed up and down by a horizontally arranged first partition plate. Inside the first cavity, it is separated into a premixing chamber 6 located inside and a cleaning liquid guiding chamber 3 surrounding the outside of the premixing chamber 6 by an annularly distributed second partition plate, so as to reasonably separate the inside of the tank body 1 into a premixing chamber 6, a cleaning liquid guiding chamber 3 and a reaction chamber. Then the material guiding hole 7 and the annular through hole 51 are both opened on the first partition plate.
[0024] Among them, since generally there are two reaction materials for the condensation reaction, the number of the feed pipes is set to two; the number of the feed pipes can also be adjusted according to actual needs. The reaction materials are introduced into the premixing chamber 6 through the feed pipes for premixing, and then are introduced into the reaction chamber through the material guiding hole 7 for reaction. The reaction products can be discharged from the discharge pipe arranged at the bottom of the tank body 1, which is beneficial to improving the yield.
[0025] In order to improve the premixing effect of the reaction materials in the premixing chamber 6, a pre-stirring blade 8 rotating in the premixing chamber 6 is connected to the stirring paddle 2. The pre-stirring blade 8 rotates with the stirring paddle 2 to stir the reaction materials in the premixing chamber 6.
[0026] As Figure 2 shown, according to another embodiment of the present utility model, for the condensation reactor, the stirring paddle 2 includes a stirring shaft 21 and mixing blades 22. The stirring shaft 21 is rotatably arranged in the reaction chamber and its top end freely passes out from the bottom of the tank body 1. There are multiple mixing blades 22 which are circumferentially distributed outside the stirring shaft 21. The multiple mixing blades 22 are correspondingly connected to the multiple cleaning conduits 4 one by one, and each mixing blade 22 is in sliding contact with the inner wall of the reaction chamber.
[0027] In this embodiment, the number of the mixing blades 22 is shown as two. After the top end of the stirring shaft 21 passes out from the top of the tank body 1, it is connected to a motor fixedly installed on the outer top of the tank body 1. The motor provides power to drive the stirring shaft 21 to rotate. The stirring shaft 21 drives the two mixing blades 22 and the two cleaning conduits 4 to rotate in the reaction chamber to stir the reaction materials; when cleaning the inside of the reaction chamber, the mixing blades 22 are all in sliding contact with the inner wall of the reaction chamber, so that the materials adhered to the inner wall of the reaction chamber can be scraped off, improving the cleaning effect on the reaction chamber.
[0028] Based on the above scheme:
[0029] Each of the mixing vanes 22 includes a vertical vane 221 and a horizontal vane 222. The vertical vane 221 is in sliding contact with the inner side wall of the reaction chamber. There are a plurality of horizontal vanes 222, and all of them are connected between the vertical vane 221 and the stirring shaft 21. The plurality of horizontal vanes 222 are spaced apart along the axial direction of the stirring shaft 21. The plurality of horizontal vanes 222 are also fixedly connected to the corresponding cleaning conduits 4, and one of the horizontal vanes 222 is in sliding contact with the inner bottom wall of the reaction chamber.
[0030] The vertical vane 221 and the plurality of horizontal vanes 222 are used to form the mixing vane 22. On the one hand, it has sufficient structural strength, and on the other hand, it has sufficient stirring ability. The cleaning conduit 4 is fixedly connected to the corresponding horizontal vane 222, which improves the structural strength of the mixing vane 22 and the installation stability of the cleaning conduit 4. Here, the cleaning conduits 4 all pass through the corresponding horizontal vanes 222.
[0031] In the condensation reaction, heat required for the reaction may be needed, such as Figure 2 As shown, according to another embodiment of the present invention, for the condensation reactor, a heating cover 9 is wrapped outside the reaction chamber. The heating cover 9 forms a spiral heating chamber outside the reaction chamber through a heat conducting plate 10 distributed in a spiral manner. One end of the spiral heating chamber is communicated with an inlet heating medium pipe, and the other end is connected with an outlet heating medium pipe.
[0032] In this embodiment, the inlet heating medium pipe is located at the bottom side of the spiral heating chamber, and the outlet heating medium pipe is located at the top side of the spiral heating chamber. The inlet heating medium pipe introduces hot water or steam into the spiral heating chamber to heat the inside of the reaction chamber, providing the heat required for the reaction in the reaction chamber. Then, the hot water or steam is discharged from the outlet heating medium pipe. A flowing heating medium can be formed in the spiral heating chamber, which is beneficial to quickly obtaining the heat required for the reaction in the reaction chamber and maintaining the reaction within a relatively constant temperature range.
[0033] Such as Figure 1 and Figure 2 As shown, according to another embodiment of the present invention, for the condensation reactor, the tank body 1 includes a tank main body 11 with an open top and a tank cover body 12 connected to the opening of the tank main body 11. The cleaning liquid guiding chamber 3 is located in the space formed inside the tank cover body 12.
[0034] Specifically, the first partition plate is arranged at the inner bottom side of the tank cover body 12, and the tank cover body 12 can be disassembled for maintenance of the inside of the tank main body 11, etc. Among them, the tank main body 11 and the tank cover body 12 are locked and fixed through a plurality of connecting pieces, and a positioning groove is formed along the circumferential direction at the top end of the tank main body 11, and a positioning block 13 matching into the positioning groove is formed on the tank cover body 12.
[0035] Here, the connecting member can be a mating bolt and nut. The cooperation of the positioning groove and the positioning block 13 can, on the one hand, improve the assembly accuracy between the tank main body 11 and the tank cover body 12, and on the other hand, can also improve the sealing performance between the tank main body 11 and the tank cover body 12 after connection.
[0036] Among them, regulating valves can be provided on the feed pipe, discharge pipe, cleaning liquid inlet pipe, heating medium inlet pipe, and heating medium discharge pipe to control their on-off.
[0037] A support frame is covered at the bottom of the tank main body 11.
[0038] When this condensation reactor is in use:
[0039] The reaction materials are added into the premixing chamber 6 from the feed pipe, and the motor is started and the heating medium is connected at the heating medium inlet pipe.
[0040] The reaction materials are premixed in the premixing chamber 6 and then enter the reaction chamber for mixing and reaction. After the reaction is completed, they are discharged through the discharge pipe.
[0041] When this condensation reactor is being cleaned:
[0042] Cleaning water with a certain pressure is added at the cleaning liquid inlet pipe. Then, the cleaning water is sprayed out in all directions from several flushing holes on each cleaning conduit 4 to flush the stirring paddle 2 and the inner wall of the reaction chamber. The flushed cleaning water is discharged from the discharge pipe to complete the pre-cleaning.
[0043] Then, the regulating valve on the discharge pipe is closed, and cleaning water continues to be connected at the cleaning liquid inlet pipe. The reaction chamber is filled with cleaning water, and then the stirring paddle 2 rotates for cleaning. After completion, the regulating valve on the discharge pipe is opened to discharge the cleaning water.
[0044] After discharging, cleaning water continues to be connected at the cleaning liquid inlet pipe. The cleaning water is sprayed out in all directions from several flushing holes on each cleaning conduit 4 to flush the stirring paddle 2 and the inner wall of the reaction chamber. The flushed cleaning water is discharged from the discharge pipe to remove the residues adhering to the stirring paddle 2 and the inner wall of the reaction chamber.
