Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically a powerful sterilization triple-effect falling film evaporator. Background Technology

[0002] A triple-effect falling film evaporator is a highly efficient evaporation device mainly used for the concentration and evaporation of materials. It employs falling film evaporation technology, transferring heat under a thin film to cause liquid evaporation. The liquid flows down from the heating surface, forming a thin film, and evaporates during the heating process. The falling film tubes are a key component of the falling film evaporator; their function is to evenly inject the heated liquid into the falling film tubes, allowing it to flow uniformly and form a thin film on the inner wall.

[0003] A search revealed that Chinese patent application number 202421787481.0 discloses a triple-effect falling film evaporator, relating to the field of evaporator technology. The key technical features include an evaporator body with a top cover and a transmission pipe at the top of the top cover; multiple falling film tubes installed on the inner wall of the evaporator body; a flow-dividing mechanism located in the middle of the inner wall of the evaporator body; and a heating mechanism located at the bottom of the inner wall of the evaporator body and on the inner wall of the top cover. The flow-dividing mechanism includes a fixing plate. The flow-dividing mechanism facilitates the uniform distribution of the incoming liquid, allowing it to flow evenly along the inner wall of the falling film tubes, preventing the liquid film from becoming too thin or forming a dry wall zone, thus avoiding damage to the falling film tubes. The heating mechanism allows for the recovery and reuse of water vapor generated during internal evaporation, using the residual heat to heat the side wall of the falling film tubes, ensuring uniform heating of the outer wall and saving fuel.

[0004] The problem with the existing technology is that when the existing triple-effect falling film evaporator is in use, the raw materials are transported to the main body of the evaporator through the transmission pipe for concentration processing. However, most of the feeding links lack the function of filtering impurities in the raw materials. Solid impurities such as fruit pulp and medicine residue contained in the raw materials can easily encapsulate microorganisms. During the sterilization process, heat must first penetrate the surface of the impurities before it can act on the internal microorganisms, which leads to the obstruction of heat transfer and reduces the overall sterilization efficiency of the evaporator. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a powerful sterilization triple-effect falling film evaporator. This evaporator has the advantage of pre-treating raw materials, thus improving sterilization efficiency. It solves the problem that in existing triple-effect falling film evaporators, raw materials are transported to the evaporator body via a transfer pipe for concentration processing, but the feeding process often lacks the function of filtering impurities from the raw materials. Solid impurities such as fruit pulp and medicinal residue in the raw materials easily encapsulate microorganisms. During sterilization, heat must first penetrate the surface of the impurities before acting on the internal microorganisms, resulting in hindered heat transfer and reduced overall sterilization efficiency of the evaporator.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a powerful sterilizing triple-effect falling film evaporator, comprising an evaporator body, a top cover, and a transmission pipe, wherein a filter mechanism is fixedly connected to the end of the transmission pipe furthest from the top cover. The filtration mechanism includes a housing and a connecting pipe, one end of which is fixedly connected to the housing, and the other end of which is fixedly connected to the transmission pipe; The inner cavity of the housing is provided with a filter assembly, and multiple fixing components are evenly distributed on the top of the outer surface of the housing.

[0007] As a preferred embodiment of the present invention, the filter assembly includes a filter bag and a fixing plate. The filter bag is located in the inner cavity of the housing, and its top passes through the housing and extends to the outside of the housing to be fixedly connected to the fixing plate. The bottom of the fixing plate contacts the housing, and the top surface is provided with a slot. The number of slots is multiple and they are evenly distributed in a ring array.

[0008] As a preferred embodiment of the present invention, the fixing component includes a support block and a locking block. The support block is fixedly connected to the housing on the side closest to the housing. The locking block is located inside the support block and is rotatably connected to the support block. Extrusion grooves are provided on both the front and rear sides.

[0009] As a preferred embodiment of this utility model, a tension spring is provided on the top of the support block, and the two ends of the tension spring are fixedly connected to the locking block and the housing, respectively.

[0010] As a preferred embodiment of the present invention, a transmission block is provided at the bottom of the support block, and an extrusion column is fixedly connected to the front and rear sides of the inner side of the transmission block. The side of the extrusion column away from the transmission block passes through the extrusion groove and extends into the inner cavity of the extrusion groove, and contacts the inner wall of the extrusion groove.

[0011] As a preferred embodiment of this utility model, the transmission block has an arc-shaped groove on the side near the housing, and an annular plate is fitted on the surface of the housing and threadedly connected to the annular plate.

[0012] In a preferred embodiment of this invention, the outer side of the annular plate is located within the inner cavity of the arc-shaped groove and contacts the inner wall of the arc-shaped groove, and an opening is provided on the outer surface. The number of openings is multiple and they are evenly distributed in a ring array.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem of existing triple-effect falling film evaporators, which, when raw materials are transported to the evaporator body through a transmission pipe for concentration processing, often lack the function of filtering impurities in the raw materials during the feeding process. Solid impurities such as fruit pulp and medicinal residue contained in the raw materials can easily encapsulate microorganisms. During the sterilization process, heat must first penetrate the surface of the impurities before it can act on the internal microorganisms, which leads to obstructed heat transfer and reduces the overall sterilization efficiency of the evaporator. This utility model achieves the function of pre-treating the raw materials and improves the sterilization efficiency.

[0014] 2. This utility model sets up a filter assembly consisting of a filter bag and a fixing plate. The filter bag can directly physically intercept solid impurities such as fruit pulp and medicinal residue in the raw materials, reducing the amount of impurities entering the main body of the evaporator from the source. Because the impurities are filtered out, the microorganisms lose their encapsulation barrier, and the heat in the sterilization process can directly act on the microorganisms, improving the uniformity and efficiency of sterilization.

[0015] 3. This utility model achieves convenient and stable fixation of the filter assembly by setting a fixing component. The transmission block drives the extrusion column to move within the extrusion groove of the locking block, which can quickly control the rotation of the locking block. Rotating the transmission block can disengage or engage the locking block with the groove of the fixing plate without the need for complicated tools, simplifying the disassembly and assembly process of the filter assembly. It is convenient for operators to regularly remove the filter bag for cleaning or replacement. The tension springs at the top of the support block are fixed to the locking block and the housing at both ends, respectively. They can provide continuous tension after the locking block engages with the fixing plate, further improving the firmness of the locking block and ensuring the stability of the filter assembly during equipment operation.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth. Example

[0025] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a powerful sterilization triple-effect falling film evaporator, including an evaporator body 1, a top cover 2, and a transmission pipe 3. A filter mechanism 4 is fixedly connected to one end of the transmission pipe 3 away from the top cover 2. The filter mechanism 4 includes a housing 41 and a connecting pipe 42. One end of the connecting pipe 42 is fixedly connected to the housing 41, and the other end is fixedly connected to the transmission pipe 3. The inner cavity of the housing 41 is provided with a filter assembly 43, and multiple fixing components 44 are evenly distributed on the top of the outer surface of the housing 41.

[0026] Specifically, by setting up a filtration mechanism 4, the problem of existing triple-effect falling film evaporators being used, where raw materials are transported to the evaporator body 1 through the transmission pipe 3 for concentration processing, is solved. However, most of these feeding processes lack the function of filtering impurities in the raw materials. Solid impurities such as fruit pulp and medicinal residue contained in the raw materials can easily encapsulate microorganisms. During the sterilization process, heat must first penetrate the surface of the impurities before it can act on the internal microorganisms, which leads to obstructed heat transfer and reduces the overall sterilization efficiency of the evaporator. This solution achieves the function of pre-treating the raw materials and improves the sterilization efficiency.

[0027] Furthermore, during use, the filter assembly 43 is first unlocked and installed via the fixing component 44 to ensure that the filter bag 431 is stably placed inside the housing 41. Then, the raw material is added to the filter bag 431 of the filter assembly 43. The filter bag 431 intercepts solid impurities such as fruit pulp and medicinal residue in the raw material. The raw material after filtering out impurities continues to flow and finally enters the inner cavity of the evaporator body 1 through the housing 41, connecting pipe 42 and transmission pipe 3. Since the raw material entering the evaporator body 1 is free of impurities that encapsulate microorganisms, the heat in the sterilization process can directly act on the microorganisms, improving the sterilization efficiency. When the filter bag 431 intercepts a lot of impurities and needs to be cleaned, the filter assembly 43 can be removed by unlocking the fixing component 44 to clean or replace the filter bag 431. The operation is convenient and does not affect the overall operation of the equipment. Example

[0028] In the second embodiment of this utility model, the filter assembly 43 includes a filter bag 431 and a fixing plate 432. The filter bag 431 is located in the inner cavity of the housing 41, and its top passes through the housing 41 and extends to the outside of the housing 41 to be fixedly connected to the fixing plate 432. The bottom of the fixing plate 432 contacts the housing 41, and the top surface is provided with a slot 433. There are multiple slots 433, which are evenly distributed in a ring array.

[0029] Specifically, by setting up a filter assembly 43, which consists of a filter bag 431 and a fixing plate 432, the filter bag 431 can directly physically intercept solid impurities such as fruit pulp and medicinal residue in the raw materials, reducing the amount of impurities entering the evaporator body 1 from the source. Because the impurities are filtered out, the microorganisms lose their encapsulation barrier, and the heat in the sterilization process can directly act on the microorganisms, improving the uniformity and efficiency of sterilization.

[0030] Furthermore, when installing the filter assembly 43, the filter bag 431 is inserted into the inner cavity of the housing 41 through the opening 9 at the top of the housing 41. At the same time, the bottom of the fixing plate 432 connected to the top of the filter bag 431 is tightly fitted to the outer surface of the housing 41 to achieve the initial positioning of the filter assembly 43. The multiple slots 433 arranged in a ring on the top of the fixing plate 432 can be engaged one by one with the locking blocks 442 of the fixing assembly 44. Through the locking action of the fixing assembly 44, the fixing plate 432 is stably fixed on the surface of the housing 41, and the position of the filter bag 431 is fixed. When it is necessary to clean impurities, after unlocking the fixing assembly 44, the fixing plate 432 can be pulled upward to remove the filter bag 431 from the inner cavity of the housing 41. The operation is simple. Example

[0031] In the third embodiment of this utility model, the fixing component 44 includes a support block 441 and a locking block 442. The support block 441 is fixedly connected to the housing 41 on the side near the housing 41. The locking block 442 is located inside the support block 441 and is rotatably connected to the support block 441. Extrusion grooves 443 are provided on both the front and rear sides.

[0032] A tension spring 444 is provided on the top of the support block 441, and the two ends of the tension spring 444 are fixedly connected to the locking block 442 and the housing 41 respectively.

[0033] A transmission block 5 is provided at the bottom of the support block 441. An extrusion column 6 is fixedly connected to the front and rear sides of the inner side of the transmission block 5. The side of the extrusion column 6 away from the transmission block 5 passes through the extrusion groove 443 and extends into the inner cavity of the extrusion groove 443, and contacts the inner wall of the extrusion groove 443.

[0034] The transmission block 5 has an arc-shaped groove 7 on the side near the housing 41, and an annular plate 8 is fitted on the surface of the housing 41 and threadedly connected to the annular plate 8.

[0035] The outer side of the annular plate 8 is located in the inner cavity of the arc groove 7 and contacts the inner wall of the arc groove 7. The outer surface is provided with openings 9. There are multiple openings 9, which are evenly distributed in a ring array.

[0036] Specifically, by setting the fixing component 44, the filter component 43 is conveniently and securely fixed. The transmission block 5 drives the squeezing column 6 to move within the squeezing groove 443 of the locking block 442, which can quickly control the rotation of the locking block 442. Rotating the transmission block 5 can disengage or engage the locking block 442 with the slot 433 of the fixing plate 432 without the need for complicated tools, simplifying the disassembly and assembly process of the filter component 43. This makes it convenient for operators to regularly remove the filter bag 431 for cleaning or replacement. The tension spring 444 at the top of the support block 441 is fixed at both ends to the locking block 442 and the housing 41, respectively. It can provide continuous tension after the locking block 442 engages with the fixing plate 432, further improving the firmness of the locking block 442 and ensuring the stability of the filter component 43 during equipment operation.

[0037] Furthermore, when locking the filter assembly 43, the annular plate 8 is rotated clockwise. Because the annular plate 8 is threadedly connected to the housing 41, the annular plate 8 will move upward along the surface of the housing 41. The outer side of the annular plate 8 contacts the inner wall of the arc groove 7 of the transmission block 5. The upward-moving annular plate 8 will push the transmission block 5 upward through the arc groove 7. The transmission block 5 drives the pressing columns 6 on both sides to move synchronously. The pressing columns 6 slide in the pressing groove 443 of the locking block 442, generating a thrust on the inner wall of the pressing groove 443, pushing the locking block 442 to rotate around the rotation point of the support block 441 towards the direction closer to the fixed plate 432, until the locking block 442 is inserted into the corresponding slot 433 at the top of the fixed plate 432. The rotation of the annular plate 8 stops, and the tension spring 444 generates a continuous tension on the locking block 442, so that the locking block 442 is tightly engaged in the slot 433, thus completing the locking of the filter assembly 43. When unlocking the filter assembly 43, rotate the annular plate 8 counterclockwise. The annular plate 8 moves downward along the surface of the housing 41. The annular plate 8 drives the transmission block 5 to move downward through the arc groove 7. The tension spring 444 is gradually stretched. The transmission block 5 drives the squeezing column 6 to slide in the opposite direction in the inner cavity of the squeezing groove 443, and pushes the locking block 442 to rotate in the opposite direction around the support block 441. The locking block 442 disengages from the slot 433, and the filter assembly 43 can be removed at this time.

[0038] During operation, the filter bag 431 is inserted into the inner cavity of the housing 41 through the top opening 9. At the same time, the bottom of the fixing plate 432, which is fixedly connected to the top of the filter bag 431, is tightly fitted to the outer surface of the housing 41. The filter assembly 43 is locked by the fixing components 44 distributed in a ring array on the outer surface of the housing 41. First, the operator uses the multiple openings 9 on the outer surface of the annular plate 8 to rotate the annular plate 8 clockwise. Since the annular plate 8 is threadedly connected to the housing 41, it moves upwards along the housing 41 during rotation. The outer side of the annular plate 8 embeds into the arc-shaped groove 7 of the transmission block 5. The upward-moving annular plate 8 exerts an upward thrust on the transmission block 5 through the inner wall of the arc-shaped groove 7, causing the transmission block 5 to move synchronously upwards along the surface of the housing 41. The pressing columns 6 fixed at the front and rear ends on the inner side of the transmission block 5 move upwards with the transmission block 5, their ends sliding within the pressing groove 443 of the locking block 442. A lateral thrust is generated on the inner wall of the extrusion groove 443. Under the action of this thrust, the locking block 442 rotates around the rotation point of the support block 441 toward the direction of the fixed plate 432 until the locking block 442 is inserted into the corresponding slot 433 on the top of the fixed plate 432, thus fixing the position of the fixed plate 432. The two ends of the tension spring 444 on the top of the support block 441 are fixed to the locking block 442 and the housing 41 respectively. At this time, the tension spring 444 is in a slightly stretched state, providing continuous tension to the locking block 442, further ensuring that the locking block 442 is tightly engaged with the slot 433. Then, the raw materials to be processed, such as liquid raw materials containing fruit pulp and medicinal residue, are slowly poured into the filter bag 431. The filter bag 431 is made of high-mesh filter material, which can directly physically intercept solid impurities in the raw materials, so that the impurities are retained in the filter bag 431. Only pure liquid raw materials are allowed to pass through the gaps in the filter bag 431. After filtration, the pure raw materials flow downward along the inner cavity of the shell 41 under the combined action of gravity and subsequent feeding pressure. They pass through the connecting pipe 42 at the bottom of the shell 41 and the transmission pipe 3 connected to the connecting pipe 42 in sequence, and are finally transported to the inner cavity of the evaporator body 1, completing the pretreatment and directional transportation of the raw materials. Since the raw materials have been pretreated to remove solid impurities, the microorganisms lose the protection of the impurities, which creates conditions for the powerful sterilization of the evaporator body 1. The evaporator body 1 operates according to the conventional process of triple-effect falling film evaporation. In the sterilization process, the heat generated by the evaporator can directly act on the microorganisms in the raw materials without first penetrating the surface of the impurities. The heat transfer efficiency is significantly improved, which improves the sterilization efficiency. When the impurities intercepted by the filter bag 431 reach a certain amount, the filter assembly 43 needs to be cleaned. The operator rotates the annular plate 8 counterclockwise through the opening 9 of the annular plate 8. The annular plate 8 moves downward along the threads of the housing 41. The annular plate 8 drives the transmission block 5 to move downward synchronously through the arc groove 7. The transmission block 5 drives the extrusion column 6 to slide in the opposite direction in the extrusion groove 443, generating a reverse thrust on the inner wall of the extrusion groove 443. At the same time, the tension spring 444 is further stretched. Under the action of reverse thrust, the locking block 442 rotates in the opposite direction around the rotation point of the support block 441 and gradually disengages from the slot 433 of the fixing plate 432. After all the locking blocks 442 are completely disengaged from the slot 433, the fixing plate 432 is pulled upward to remove the filter bag 431 from the inner cavity of the housing 41 for cleaning or replacement. After cleaning or replacement, reinstall the filter assembly 43 according to the installation and fixing procedure to restore the equipment to the standby state and ensure the continuous stability of the subsequent raw material pretreatment and sterilization process.

[0039] In summary, by setting up the filtration mechanism 4, the function of pre-treating raw materials is achieved, thereby improving the sterilization efficiency.
