Description

Technical Field

[0001] The present invention relates to the technical field of flash evaporators, and specifically to a biodiesel heating flash evaporation device. Background Art

[0002] Flash evaporation is a phenomenon in which a high-pressure saturated liquid enters a relatively low-pressure container, and due to the sudden drop in pressure, part of the saturated liquid becomes saturated steam and saturated liquid under the pressure of the container. A flash evaporation device generally refers to a flash dryer, which is a device that utilizes the difference in saturated vapor pressure of substances under different pressures to rapidly evaporate liquid substances by reducing the pressure, thereby achieving gas-liquid separation.

[0003] Biodiesel is a renewable and environmentally friendly liquid fuel. It is mainly made from oil crops (such as soybeans, rapeseed, cotton, palm, etc.), wild oil plants, aquatic plant oils such as engineering microalgae, as well as animal fats and restaurant waste oil through transesterification or thermochemical processes. It can be used to replace or blend with traditional petrochemical diesel. The preparation process of biodiesel mainly includes stages such as raw material pretreatment, transesterification reaction, glycerol separation, and product refining. Among them, in the dehydration drying and product separation stages, a flash dryer is used to remove low-component substances and water vapor.

[0004] The raw materials for biodiesel preparation (such as animal and vegetable oils, restaurant waste oil, etc.) have high viscosity characteristics. During the flash drying process, when the material temperature is lower than its softening point or the operating pressure fluctuates, a viscous adhesion layer is likely to form on the surface of the broken pieces. This adhesion phenomenon can cause multiple negative impacts: First, the surface roughness of the broken pieces increases, the effective contact area between the material particles and the crushing elements decreases, and the crushing efficiency is reduced; Second, the thermal conductivity of the adhesion layer is significantly lower than that of the metal substrate, forming a heat insulation barrier and weakening the heat transfer efficiency during the flash drying process; Third, as the thickness of the adhesion layer increases, the dynamic balance performance of the crushing elements deteriorates, the equipment vibration intensifies, and the service life of mechanical components is shortened. Existing flash drying equipment alleviates this problem by increasing the ambient temperature or the crushing frequency, but high temperatures are likely to cause thermal degradation of the material, while mechanical strengthening means will lead to increased energy consumption and noise pollution; Therefore, it does not meet the existing requirements, and for this reason, we propose a biodiesel heating flash evaporation device. Summary of the Invention

The swinging heat collection and conduction component includes a mounting frame installed above the first heat absorption plate. A swinging gear is installed in the mounting frame, and a second heat absorption plate is fixedly connected to the side wall of the swinging gear. The second heat absorption plate expands the contact area with the hot air through swinging.

[0016] As an alternative embodiment of the biodiesel heating flash evaporation device of the present invention, wherein: the swinging gear is meshed with a driving rack, the top of the driving rack is fixedly connected with a slider, and the slider is slidably connected in a track groove opened in the crushing block.

[0017] The present invention has the following beneficial effects: 1. For the biodiesel heating flash evaporation device, by arranging a heat collection component in the crushing block, the waste heat resources in the flash evaporator housing are recovered and reused, improving the thermal energy utilization efficiency of the device. The collaborative design of the heat collection groove and the heat conduction fan enables the high-temperature gas flow heat in the hot air output channel to be actively captured by the annular heat collection plate, and the heat is directionally transported to the surface of the crushing block by the rotating heat conduction fan, forming a continuous local heating effect. This design effectively prevents the oily substances in the biodiesel raw materials from adhering to the crushing block during the crushing process, thus maintaining the structural integrity and functional stability of the crushing block. The constant temperature state of the crushing block can ensure that the raw material particles are always in the best thermodynamic conditions during crushing. In long-term operation, this design can also reduce the frequency of shutdown and cleaning caused by material adhesion, extend the service life of the equipment, reduce the maintenance cost, and provide a reliable guarantee for the continuous production of biodiesel.

[0018] 2. The biodiesel heating flash device solves the problem of pressure accumulation caused by continuous heat storage in the heat collecting tank through the linkage of the pressure relief block and the pressure relief spring. When the internal pressure exceeds the set threshold, the pressure relief block moves upward under the drive of the pressure difference, so that the closed channel and the pressure relief channel are instantly connected, and the high-pressure gas is quickly released to the external environment; after the pressure is balanced, the pressure relief spring automatically resets the seal to ensure that the heat collecting tank returns to a closed state. This dynamic pressure regulation mode has dual advantages: on the one hand, intermittent pressure relief can prevent the broken blocks from being subjected to high pressure stress for a long time and prevent the occurrence of material fatigue cracks; on the other hand, the short pressure relief process releases pressure while precisely controlling the pressure relief time, allowing only a small amount of heat to be lost, ensuring that the surface temperature of the broken blocks does not fluctuate too much, effectively maintaining the critical temperature range required for its anti-adhesion, and perfectly balancing the contradiction between temperature stability and pressure safety while ensuring the durability of the equipment.

[0019] 3. The biodiesel heating flash evaporation device has achieved a step-by-step improvement in the efficiency of hot air energy capture through the innovative structural design of the swing collection heat conduction component. Under the mechanical coupling of the track groove and the drive rack, the No. 2 heat absorption plate swings periodically at a certain frequency, so that its effective heating area is expanded compared with the static structure. When the No. 2 heat absorption plate swings outward, its unfolded fin structure can intercept more hot air flow and increase the heat energy absorption rate; in the inward swing stage, the accumulated heat is efficiently transferred to the No. 1 heat absorption plate through physical contact. This dynamic heat absorption mechanism increases the heat storage speed of the heat collection tank and the surface of the broken block can quickly reach the working temperature after startup, which greatly shortens the preheating time compared with the traditional design. At the same time, the airflow disturbance effect generated by the swing can break the laminar boundary layer in the hot air output channel, enhance the turbulence intensity, and improve the overall heat exchange efficiency. This component not only significantly accelerates the process of the equipment entering steady-state operation, but also reduces the risk of local overheating by optimizing the heat energy distribution, so that the temperature uniformity deviation of the broken block is controlled within a certain range, providing an ideal thermal environment condition for the fine drying of biodiesel raw materials.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In Embodiment 1, this embodiment aims to facilitate the solution of the problem that the adhesion of grease to the surface of the crushing block 24 leads to a decrease in crushing efficiency. Please refer to Figures 1 to 8 , a biodiesel heating flash evaporation device, including a flash evaporation device 1, the flash evaporation device 1 includes a flash evaporator housing 11, a crushing device 2 is installed in the flash evaporator housing 11, the crushing device 2 includes a crushing rotating disk 23, a crushing block 24 is installed on the crushing rotating disk 23, and a heat collecting assembly 4 is installed in the crushing rotating disk 23 and the crushing block 24.

[0031] The side wall of the flash evaporator housing 11 is provided with a feed pipe 12 and a heating pipe 14. A feed screw 13 is arranged inside the feed pipe 12. An air suction device 15 is arranged at the top of the flash evaporator housing 11.

[0032] The crushing device 2 includes a crushing installation housing 21 installed inside the flash evaporator housing 11. A crushing rotating disk 23 is installed inside the crushing installation housing 21. A driving motor 22 is installed at the bottom of the crushing rotating disk 23. Crushing blocks 24 are installed on the side wall of the crushing rotating disk 23. A hot air output channel 25 is formed inside the crushing rotating disk 23 and the crushing blocks 24.

[0033] During the preparation of biodiesel, a series of pretreatment processes such as drying are required first to prepare for subsequent processes. For the drying of raw materials, a flash evaporation device 1 is usually used for drying. The raw materials enter the flash evaporator housing 11 through the feed pipe 12 and the feed screw 13 of the flash evaporation device 1. The heating pipe 14 conveys hot air into the flash evaporator housing 11. At the same time, the air suction device 15 at the top changes the air pressure inside the flash evaporator housing 11. Through the characteristic of low boiling point under low pressure state, rapid drying is achieved. The crushing device 2 is used to crush the raw material particles to increase the contact area between the raw materials and hot air and improve the drying efficiency. And under the action of the air suction device 15, the crushed and dried raw materials are conveyed from the top to the collection device for subsequent process processing (the above structure and principle are prior arts, so this solution will not be described in detail herein).

[0034] The heat collection component 4 includes a heat collection groove 46 arranged inside the crushing block 24. The heat collection groove 46 is used to collect heat and store it to heat the crushing block 24.

[0035] A rotating component 3 is arranged inside the crushing rotating disk 23. The rotating component 3 includes an I-shaped groove 31 formed inside the crushing rotating disk 23. An I-shaped rotating block 32 is rotatably connected inside the I-shaped groove 31. A first gear 34 is arranged at the bottom of the I-shaped rotating block 32. The first gear 34 is meshed with an annular tooth groove 33, and the annular tooth groove 33 is formed inside the crushing installation housing 21.

[0036] A first annular groove 35 and a second annular groove 38 are formed inside the I-shaped rotating block 32. An annular heat collection plate 36 is installed inside the first annular groove 35. A heat collection guiding annular block 37 is installed inside the second annular groove 38. One side of the heat collection guiding annular block 37 is connected to the annular heat collection plate 36. The other side of the heat collection guiding annular block 37 is fixedly connected to a first heat absorption plate 39, and the first heat absorption plate 39 is arranged inside the heat collection guiding annular block 37.

[0037] The heat collection assembly 4 includes a heat conduction groove 41 formed in the I-shaped rotating block 32. An installation rod 42 is installed in the heat conduction groove 41, and a heat conduction fan 43 is installed in the installation rod 42. The fan blades of the heat conduction fan 43 are arranged below the heat conduction groove 41, and the fan blades of the heat conduction fan 43 are located above the annular heat collection plate 36. The heat conduction groove 41 communicates with the heat collection groove 46.

[0038] The top of the heat conduction fan 43 is fixedly connected with a fan gear 44, and the fan gear 44 is meshed with a second gear 45. The second gear 45 is arranged in the heat collection groove 46.

[0039] The design of the heat collection groove 46 is used to concentrate part of the heat in the flash evaporator housing 11 in the crushing block 24. This design can increase the surface temperature of the crushing block 24, so that these oily substances will not easily adhere to the surface of the crushing block 24, ensuring the cleanliness of the crushing block 24.

[0040] With the drive of the drive motor 22, the crushing rotating disk 23 starts to rotate in the crushing installation housing 21. At this time, the I-shaped rotating block 32 installed in the crushing rotating disk 23 starts to rotate in the I-shaped groove 31 under the drive of the annular tooth groove 33 and the first gear 34. And a heat conduction fan 43 is installed in the I-shaped rotating block 32. Since the crushing block 24 is fixedly installed on the surface of the crushing rotating disk 23, the I-shaped rotating block 32 rotates relative to the crushing block 24. Therefore, the heat conduction fan 43 in the I-shaped rotating block 32 rotates relative to the fan gear 44 fixedly connected in the crushing block 24. Due to the meshing of the fan gear 44 and the second gear 45, and the rotation of the I-shaped rotating block 32, the heat conduction fan 43 starts to rotate. And below the heat conduction fan 43, there are an annular heat collection plate 36, a heat collection guiding annular block 37 and a first heat absorption plate 39. The first heat absorption plate 39 is arranged in the hot air output channel 25 to receive the heat of the hot air passing through the hot air output channel 25, and transfer it to the surface of the annular heat collection plate 36 through the heat collection guiding annular block 37. Then, through the rotation of the heat conduction fan 43, the heat is transferred to the heat collection groove 46. Through this design, the crushing block 24 can be continuously heated, thus avoiding the adhesion of oily substances to the surface of the crushing block 24, ensuring the cleanliness of the crushing block 24, and further ensuring the crushing effect of the device.

[0041] Embodiment 2. This embodiment is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1 to 8 , an intermittent pressure relief component 5 is arranged in the crushing block 24. The intermittent pressure relief component 5 is used to intermittently relieve the high pressure generated in the heat collection groove 46 due to heating. The intermittent pressure relief component 5 includes a pressure relief channel 51 and a pressure relief installation groove 52 formed in the crushing block 24. A pressure relief block 54 is slidably connected in the pressure relief installation groove 52. A pressure relief spring 53 is installed between the pressure relief block 54 and the pressure relief installation groove 52. A closed channel 55 is formed in the pressure relief block 54.

[0042] Due to continuous heat collection within the broken piece 24, this will cause the pressure within the heat collection groove 46 to continuously increase. The broken piece 24 is in a high-pressure state for a long time, which may damage the quality of the broken piece 24 itself. Therefore, it is necessary to intermittently relieve the pressure of the broken piece 24 through the intermittent pressure relief component 5. This process ensures the stability of the structure of the broken piece 24 itself while ensuring the high temperature on the surface of the broken piece 24.

[0043] When the temperature in the heat collection groove 46 rises, the internal pressure continuously increases. Therefore, it will drive the pressure relief block 54 to slide upward. After the pressure relief block 54 slides upward for a certain distance, the closed channel 55 within the pressure relief block 54 communicates with the pressure relief channel 51, and the pressure relief channel 51 communicates with the outside. At this time, the high-pressure environment within the heat collection groove 46 comes into contact with the low-pressure environment outside, and the pressure within the heat collection groove 46 will quickly be discharged outward through the closed channel 55 and the pressure relief channel 51, thereby alleviating the high-pressure situation within the broken piece 24. When the internal pressure is the same as that of the outside, under the action of the pressure relief spring 53, the pressure relief block 54 slides downward to re-block the pressure relief channel 51. At this time, the inside becomes a closed space again to avoid contact with the low-pressure environment outside for a long time, resulting in a decrease in the internal temperature. And the oily substance will adhere to the surface of the broken piece 24 in a lower-temperature environment. Therefore, through this intermittent pressure relief process, while ensuring the high temperature on the surface of the broken piece 24, the stability of the structure of the broken piece 24 itself is ensured.

[0044] Embodiment 3. This embodiment is an explanatory description based on Embodiment 2. Specifically, please refer to Figures 1 to 8 , a swinging heat collection and heat conduction component 6 is arranged in the hot air output channel 25. The swinging heat collection and heat conduction component 6 includes a mounting frame 61 installed above the first heat absorption plate 39. A swinging gear 62 is installed within the mounting frame 61. A second heat absorption plate 63 is fixedly connected to the side wall of the swinging gear 62. The second heat absorption plate 63 expands the contact area with the hot air through swinging.

[0045] The swinging gear 62 is meshed and connected with a driving rack 64. The top of the driving rack 64 is fixedly connected with a slider 65. The slider 65 is slidably connected within a track groove 66. The track groove 66 is opened within the broken piece 24.

[0046] The design of the swinging heat collection and conduction component 6 is used to improve the efficiency of the first heat absorption plate 39 in absorbing heat from the hot air output channel 25. As mentioned before, the broken block 24 rotates relative to the I-shaped rotating block 32, and the second heat absorption plate 63 and the driving rack 64 are installed in the I-shaped rotating block 32. Therefore, when the I-shaped rotating block 32 rotates, the driving rack 64 rotates together with the I-shaped rotating block 32. The top of the driving rack 64 is provided with a slider 65, and the slider 65 is slidably connected in the track groove 66 in the broken block 24. Therefore, during the rotation of the I-shaped rotating block 32, the slider 65 and the driving rack 64 fixedly connected to the slider 65 are driven to slide up and down. Through this sliding, the swinging gear 62 meshed with the driving rack 64 is driven to swing and rotate. Since the second heat absorption plate 63 is fixedly connected to one side of the swinging gear 62, the second heat absorption plate 63 will also continuously swing in the hot air output channel 25. When the second heat absorption plate 63 swings outwards, the contact area with the hot air flow will increase. When the second heat absorption plate 63 swings inwards, through the mutual contact between the second heat absorption plate 63 and the first heat absorption plate 39, the heat in the second heat absorption plate 63 is transferred to the first heat absorption plate 39, and then conveyed to the surface of the broken block 24. Through this design, the heat storage efficiency in the heat collection groove 46 can be improved, thereby ensuring the rate of increase in the temperature of the surface of the broken block 24, and then quickly bringing the equipment into a good working state. At the same time, the air flow disturbance effect generated by the swinging can break the laminar boundary layer in the hot air output channel 25, enhance the turbulence intensity, and improve the overall heat transfer efficiency.

[0047] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0048] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
