TECHNICAL FIELD

[0001] The utility model belongs to the related technical field of concentration device for compound processing, specifically relates to a concentration device for cucurbituril compound processing. BACKGROUND

[0002] Cucurbituril compounds have potential application value in many fields. During its processing, the reaction system or solution often needs to be concentrated. Traditional concentration devices may face problems such as easy blockage, low concentration efficiency, and difficulty in accurately controlling the concentration degree when processing cucurbituril compounds due to the special structure and properties of cucurbituril. Moreover, as the research and application of cucurbituril compounds are further developed, the performance and applicability of the concentration device for processing cucurbituril compounds are increasingly improved, which promotes the research and development of more professional, efficient, and targeted concentration devices for processing cucurbituril compounds.

[0003] Traditional evaporation concentration devices usually do not make good use of steam waste heat during the steam condensation process, resulting in a large amount of heat being wasted. There is a lack of a waste heat recovery structure in the section of the pipeline between the evaporation tank and the condenser, which can heat the storage cylinder by setting a waste heat recovery structure, reducing the amount of steam used for heating raw materials in the evaporation tank, and solving the problem of low energy utilization rate of traditional equipment. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a concentration device for cucurbituril compound processing to solve the problem of the traditional evaporation concentration device in the steam condensation process, which usually does not make good use of steam waste heat, resulting in a large amount of heat being wasted. There is a lack of a waste heat recovery structure in the section of the pipeline between the evaporation tank and the condenser.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a concentration device for cucurbituril compound processing, comprising an evaporation tank, a storage cylinder arranged at the right side position of the evaporation tank, and a condenser arranged at the right lower side position of the storage cylinder.

[0006] The lower side positions of the evaporation tank, the storage cylinder, and the condenser are provided with a stepped frame;

[0007] The lower side of the storage cylinder and the evaporation tank are provided with a feed pipe in communication, and the upper side of the evaporation tank is connected with a condensation pipe;

[0008] A window is formed at the front side middle position of the evaporation tank, and a discharge pipe is arranged at the lower side position of the condenser;

[0009] The distal end of the condensation pipe and the outer side of the storage cylinder are connected with a heat recovery pipe, and the distal end of the heat recovery pipe and the upper side of the condenser are connected with a connecting pipe;

[0010] The middle inner side position of the evaporation tank is provided with a rotating rod, the rotating rod and the left inner wall of the evaporation tank are connected with a sealing ring, and the right outer side of the rotating rod is provided with a plurality of stirring blades.

[0011] Preferably, the rear side position of the evaporation tank is communicated with a steam pipe, and the rear side position of the storage cylinder is provided with a feeding pipe.

[0012] Preferably, the upper left side position of the storage cylinder is provided with a valve pipe, and the valve pipe is connected with an outer side feeding pump device.

[0013] Preferably, the ladder frame is provided with two layers, the evaporation tank and the storage cylinder are arranged in the upper layer, and the condenser is arranged in the bottom layer.

[0014] Preferably, the heat recovery pipe is arranged around the storage cylinder in multiple circles, and the right end of the rotating rod is connected with the evaporation tank in a sleeving embedding mode.

[0015] Preferably, the plurality of stirring blades are connected with the rotating rod in a welding connection mode.

[0016] Preferably, the rotating rod can rotate in the inner side of the evaporation tank, the left end position of the rotating rod is provided with a handle, and the inner side of the stirring blade is provided with a plurality of filter holes.

[0017] Compared with the prior art, the utility model provides a kind of concentrated device for processing cucurbituril compound, with the following beneficial effects:

[0018] 1, the device breaks temperature gradient using stirring structure, so that the whole raw material liquid temperature is uniformly distributed. This means that more liquid can quickly reach boiling point, accelerating the evaporation speed of the solvent. For example, without stirring, only the part of liquid near the heat source (tank wall) can evaporate faster, while the center part of liquid evaporates slowly. After stirring, the evaporation process of the whole liquid is more synchronized, thereby improving the overall efficiency of evaporation concentration.

[0019] In addition, for solute and solvent mixed system, it is crucial to prevent solute from precipitating. Precipitated solute may accumulate at the bottom of the tank, not only affecting the effective use of solute, but also possibly causing local concentration to be too high, affecting product quality. The stirring blade ensures uniform dispersion of solute in the solvent, so that the solute concentration in each part of the liquid can uniformly rise during the concentration process, which helps to produce stable quality and uniform composition of cucurbituril compound concentrated product.

[0020] 2. The filter holes inside the stirring blades allow the liquid to circulate, further enhancing the mixing effect and enabling better integration of the various components of the raw material liquid. Simultaneously, the filter holes prevent large particles or undissolved solids from moving around during stirring, avoiding wear or blockage of the evaporator's internal structure, extending the equipment's lifespan, and reducing maintenance costs.

[0021] 3. By installing heat recovery pipes, waste heat from the steam is effectively recovered and transferred to the raw materials entering the evaporator for preheating. This reduces the amount of steam used to heat the raw materials in the evaporator, thus lowering energy consumption. For example, in chemical production, energy costs typically account for a large proportion of total costs; this heat recovery measure can significantly reduce production costs and improve energy efficiency.

[0022] Furthermore, the multi-coil design of the regenerator tubes surrounding the storage tank increases the contact area and time between the steam and the raw material inside the storage tank. This allows the raw material to absorb the residual heat of the steam more fully, resulting in better preheating. Compared to simple heat exchange structures, this design allows the raw material to reach a higher temperature before entering the evaporator, thereby further shortening the heating time in the evaporator and accelerating the entire concentration process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figures 1-4 The illustrated concentrator for processing cucurbita compounds includes an evaporator 10, a storage cylinder 6 located on the right side of the evaporator 10, and a condenser 2 located on the lower right side of the storage cylinder 6.

[0030] A stepped rack 1 is provided at the lower side of the evaporator 10, the storage cylinder 6, and the condenser 2;

[0031] A feed pipe 7 is provided on the lower side of the storage cylinder 6 and the evaporator 10, and a condenser pipe 9 is connected to the upper side of the evaporator 10.

[0032] A viewing window 11 is provided at the middle of the front side of the evaporator 10, and a discharge pipe 3 is provided at the lower side of the condenser 2.

[0033] A heat recovery pipe 5 is connected to the end of the condenser tube 9 and the outside of the storage cylinder 6, and a connecting pipe 4 is connected to the end of the heat recovery pipe and the upper side of the condenser 2.

[0034] A rotating rod 16 is provided at the middle inner side of the evaporator 10. A sealing ring 14 is connected to the rotating rod 16 and the left inner wall of the evaporator 10. Multiple stirring blades 13 are provided on the right outer side of the rotating rod 16.

[0035] In this embodiment, the raw material enters the storage cylinder 6 through the feeding pipe on the rear side of the storage cylinder 6. The raw material can be transported to the storage cylinder 6 by a feed pump connected to the valve pipe 8.

[0036] The raw materials in the storage cylinder 6 enter the evaporator 10 through the feed pipe 7.

[0037] Steam enters the evaporator 10 through the steam pipe at the rear of the evaporator 10 to heat the raw materials inside the evaporator 10.

[0038] The raw material is heated and evaporated in the evaporator 10, and the solvent (water) turns into steam.

[0039] During the evaporation process, the situation inside the evaporator 10 can be observed through the viewing window 11.

[0040] The steam generated by evaporation enters the condenser 2 through the condenser tube 9.

[0041] In condenser 2, the steam is cooled and recondensed into liquid.

[0042] The condensed liquid is discharged through the discharge pipe 3 for collection.

[0043] After the steam flows in the regenerative pipe 5, it enters the condenser 2 for condensation through the connecting pipe 4.

[0044] Principle: The device uses the steam input by the steam pipe as a heat source to heat the raw materials in the evaporation tank 10. When the temperature of the raw materials reaches the boiling point, the solvent begins to evaporate into steam, and the solute remains in the evaporation tank 10 and gradually concentrates.

[0045] After the steam enters the condenser 2, the cooling effect (cooling medium) of the condenser 2 lowers the temperature of the steam, causing the steam to re-condense into liquid, realizing gas-liquid conversion, and facilitating collection and processing.

[0046] The device uses the regenerative pipe 5 to transfer the heat from the steam coming out of the evaporation tank 10 to the raw materials in the storage cylinder 6, realizing heat recovery. This helps to improve energy utilization and reduce energy consumption.

[0047] Through the above operation mode and working principle, the device realizes the concentration operation in the processing of cucurbituril compounds, ensuring the efficiency of production and the rational use of energy.

[0048] As shown in Figures 1-2 The rear side of the evaporation tank 10 is connected to a steam pipe, the rear side of the storage cylinder 6 is provided with a feeding pipe, the upper left side of the storage cylinder 6 is provided with a valve pipe 8, the valve pipe 8 is connected to an external feeding pump device, the ladder stand 1 is provided with two layers, the evaporation tank 10 and the storage cylinder 6 are arranged in the upper layer, and the condenser 2 is arranged in the bottom layer.

[0049] As shown in Figures 1-4 The regenerative pipe 5 is arranged around the storage cylinder 6 in multiple turns, the right end of the rotating rod 16 is connected to the evaporation tank 10 through a sleeve embedding connection, the multiple stirring blades 13 are connected to the rotating rod 16 through a welding connection, the rotating rod 16 can rotate inside the evaporation tank 10, the left end of the rotating rod 16 is provided with a handle 12, and the inside of the stirring blade 13 is provided with multiple filter holes 15.

[0050] Preferably, the operating personnel can manually rotate the rotating rod 16 through the handle 12 at the left end of the rotating rod 16, or drive the rotating rod to rotate through an external power device, so that the rotating rod 16 rotates inside the evaporation tank 10. Since the multiple stirring blades 13 are connected to the rotating rod 16 through a welding connection, the stirring blades 13 will also rotate.

[0051] During the evaporation and concentration process, the stirring blades 13 continuously rotate in the raw material liquid, ensuring that the raw material liquid can be fully mixed.

[0052] The rotation of the stirring blade 13 can break the temperature gradient and concentration gradient of the raw material liquid in the evaporation tank 10. When the steam heats the raw material liquid, the liquid near the tank wall can be higher in temperature, and the liquid in the central part can be lower in temperature. The stirring action can uniformly distribute the heat and accelerate the evaporation speed.

[0053] For a mixed system of solute and solvent, the stirring blade 13 can prevent the solute from precipitating at the bottom of the tank and ensure the uniform dispersion of the solute in the solvent. The multiple filter holes 15 arranged on the inner side of the stirring blade 13 can allow the liquid to flow in a circulating manner through the filter holes 15 during the stirring process. On the one hand, the filter holes 15 can prevent large-particle impurities or unsolved solids from damaging the equipment by moving around during the stirring process. On the other hand, the circulating flow further enhances the mixing effect of the liquid, which is conducive to the evaporation of the solvent and the concentration of the solute.

[0054] The steam from the condenser pipe 9 of the evaporation tank 10 enters the regenerative pipe 5, which surrounds the storage cylinder 6 in multiple turns. The steam flows in the regenerative pipe 5, and the heat is transferred to the raw material in the storage cylinder 6 through the pipe wall of the regenerative pipe 5.

[0055] The steam after heat transfer enters the condenser 2 through the connecting pipe 4 for condensation.

[0056] The regenerative pipe 5 works based on the principle of heat conduction. When the steam flows in the regenerative pipe 5, its temperature is higher than that of the raw material in the storage cylinder 6. According to the second law of thermodynamics, the heat will automatically transfer from the high-temperature steam to the low-temperature raw material.

[0057] The design of the regenerative pipe 5 surrounding the storage cylinder 6 in multiple turns can increase the contact area and contact time between the steam and the raw material in the storage cylinder 6, thereby improving the efficiency of heat recovery. In this way, the waste heat of the steam generated during the evaporation process can be effectively utilized to preheat the raw material about to enter the evaporation tank 10, thereby reducing the amount of steam used for heating the raw material in the evaporation tank 10 and achieving the purpose of energy saving.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
