Description

Technical Field

[0001] The utility model belongs to the field of chemical equipment, in particular to a continuous production device for cooling and crystallizing organic matter. Background Art

[0002] The cooling crystallization method is a common organic crystallization process. During the treatment, the staff needs to set up a pre-crystallizer between the material storage tank and the granulator, so that the material entering the granulator carries a certain amount of crystal seeds, which improves the crystallization speed and effect of the material in the subsequent treatment process.

[0003] When seeds appear inside the material, the turbidity of the material will change. Since the turbidity of the material will affect the effect of the subsequent granulation, the staff needs to adjust the seed content inside the material according to the actual process requirements to make the turbidity of the material match the actual requirements.

[0004] However, the pre-crystallizer in the prior art cannot flexibly control the seed content in the material, so it is difficult for the staff to adjust the turbidity of the material during actual use. At the same time, the traditional pre-crystallizer is prone to cause the material to stick to the scraper and the stirring shaft when rotating and scraping the wall, so it can only work intermittently and cannot produce continuously, thus affecting the crystallization and granulation efficiency of organic matter.

When the material enters the pre-crystallizer, the cold medium in the cold medium cavity can cool the material close to the inner wall of the material cavity, causing the material to crystallize on the inner wall of the material cavity, and the material is scraped off by the scraper assembly to form crystal seeds in the material.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] Figure 1 A schematic flow diagram of a continuous production device for cooling and crystallizing an organic substance provided in this embodiment, as shown in the figure, comprises a material storage tank 11, a feed pump 12, a pre-crystallizer 13, a discharge pump 14 and a granulation device 15 connected in sequence through pipelines. When in use, the material to be processed should be stored in the material storage tank 11, and the temperature of the material should be adjusted according to the process requirements. The feed pump 12 can allow the material to enter the pre-crystallizer 13 so that the material generates crystal seeds in the pre-crystallizer 13. Then, the material containing the crystal seeds will enter the granulation device 15 under the action of the discharge pump 14 for granulation treatment to obtain a solid material product.

[0037] It should be noted that the granulation equipment 15 in this embodiment can be a common pointed-mouth dripping steel belt machine, a slicer, a spray granulation tower or other existing granulation devices. The staff can select and use the existing granulation device according to the type of material to be processed, so as to process the material with crystal seeds into the desired solid product.

[0038] Figure 2-Figure 6 The schematic diagram of the pre-crystallizer 13 is shown in the figure. In this embodiment, the pre-crystallizer 13 includes: an outer shell 2, an inner shell 3 and a plurality of scraper assemblies. A material cavity 21 is provided inside the outer shell 2, and the inner shell 3 is rotatably arranged inside the material cavity 21. A crystallization gap is formed between the outer wall of the inner shell 3 and the inner wall of the material cavity 21. The plurality of scraper assemblies are arranged on the outer wall of the inner shell 3, and the plurality of scraper assemblies are arranged in a ring shape around the axis of the inner shell 3. In order to facilitate the entry and exit of the material into and out of the pre-crystallizer 13, a feed pipe 211 and a discharge pipe 212 connected to the material cavity 21 should be provided at both ends of the outer shell 2, respectively, and the feed pipe 211 is connected to the feed pump 12, and the discharge pipe 212 is connected to the discharge pump 14.

[0039] When in use, the material entering the pre-crystallizer 13 will cool down and crystallize on the inner wall of the material cavity 21. At this time, the rotation of the inner shell 3 can cause the scraper assembly to scrape the inner wall of the material cavity 21, so that the crystals on the inner wall of the material cavity 21 fall into the material to form crystal seeds.

[0040] In order to facilitate the control of the amount of seed crystals generated inside the pre-crystallizer 13, the present embodiment is provided with a cold medium cavity 22 inside the side wall of the outer shell 2 for accommodating a cold medium (for example, common heat-conducting media such as low-temperature water or low-temperature oil whose temperature is lower than the crystallization temperature of the material), and a cold medium inlet pipe 221 and a cold medium outlet pipe 222 connected to the cold medium cavity 22 are provided on the outer shell 2 to facilitate the circulation of the cold medium.

[0041] Since the crystallization speed of the material is related to the temperature (usually, the lower the temperature, the faster the crystallization speed of the material), the temperature and flow rate of the cold medium can control the temperature of the inner wall of the material cavity 21, thereby adjusting the crystallization speed of the material inside the pre-crystallizer 13. When the rotation speed of the inner shell 3 remains unchanged, the faster the crystallization speed of the material, the higher the seed content inside the pre-crystallizer 13 per unit time, so the staff can adjust the temperature and flow rate of the cold medium inside the pre-crystallizer 13 according to actual needs, so that the number of seed crystals generated inside the pre-crystallizer 13 matches the actual needs.

[0042] In addition, in order to avoid material adhesion on the scraper assembly, a heat medium cavity 31 for accommodating heat medium (such as common heat-conducting medium such as high-temperature water or high-temperature oil with a temperature equal to the crystallization temperature of the material) should be provided inside the inner shell 3. To facilitate the flow of the heat medium, one end of the flow guide assembly should be inserted into the heat medium cavity 31, and a heat medium inlet pipe 441 and a heat medium outlet pipe 442 connected to the heat medium cavity 31 are provided at the other end of the flow guide assembly, so that the heat medium can flow in and out by means of the heat medium inlet pipe 441 and the heat medium outlet pipe 442.

[0043] Since the heat medium can increase the temperature of the inner shell 3, and the scraper assembly is arranged on the outer wall of the inner shell 3, the staff can heat the scraper assembly by adjusting the temperature and flow rate of the heat medium, thereby preventing the pre-crystallizer 13 from being unable to continue production due to material adhesion in the scraper assembly.

[0044] As an optional implementation of this embodiment, in order to facilitate the staff to judge the seed content inside the device and flexibly adjust the temperature and flow rate of the cold and hot media, a turbidity meter 16 may be further provided on the pipeline between the pre-crystallizer 13 and the discharge pump 14, so that the seed content in the material can be reflected by the indication of the turbidity meter 16, thereby improving the operational convenience of the staff.

[0045] Figure 3 is a cross-sectional view of the pre-crystallizer 13, Figure 4 The exploded diagram of the pre-crystallizer 13 is shown in the figure. To improve the heat exchange efficiency between the scraper assembly and the heat medium, the flow guide assembly described in this embodiment may include an inflow section 41, a flow guide section 42, an outflow section 43 and a connection section 44 connected in sequence, and the heat medium inflow pipe 441 and the heat medium outflow pipe 442 are both arranged on the connection section 44. To facilitate the heat medium to enter and exit the heat medium cavity 31, an inflow hole 411 is provided on the side wall of the inflow section 41, and an inflow channel 412 is provided inside the flow guide assembly, and the inflow hole 411 is connected to the heat medium inflow pipe 441 through the inflow channel 412. Correspondingly, an outflow hole 431 is provided on the side wall of the outflow section 43, and an outflow channel 432 is provided inside the flow guide assembly, and the outflow hole 431 is connected to the heat medium outflow pipe 442 through the outflow channel 432.

[0046] After assembly, the inflow section 41, the guide section 42 and the outflow section 43 are all placed inside the heat medium cavity 31, and the connecting section 44 is placed outside the heat medium cavity 31. During operation, the heat medium will enter the guide assembly along the heat medium inflow pipe 441, and enter the heat medium cavity 31 along the inflow hole 411. After the heat medium completes the heat exchange with the inner shell 3 and the scraper assembly, it will enter the guide assembly along the outflow hole 431, and flow to the outside of the guide assembly along the heat medium outflow pipe 442.

[0047] Optionally, in order to improve the heat exchange effect between the heat medium and the inner shell 3 and the scraper assembly, the outer diameters of the inflow section 41 and the outflow section 43 should be smaller than the outer diameter of the guide section 42, and a heat exchange gap should be formed between the outer wall of the guide section 42 and the inner wall of the heat medium cavity 31. When the heat medium enters the heat medium cavity 31, the gap size of the heat exchange gap is small, so when the heat medium enters the heat exchange gap, the flow rate of the heat medium will increase, so that the heat exchange speed between the heat medium and the inner shell 3 can be accelerated, so that the heat can be transferred to the scraper assembly faster.

[0048] In addition, in order to further improve the heat exchange efficiency between the heat medium and the inner shell 3, as Figure 6 As shown, a spiral guide strip 311 may be further provided on the inner side wall of the heat medium cavity 31. When the inner shell 3 rotates, the spiral guide strip 311 can form turbulent flow inside the heat medium, thereby accelerating the heat transfer speed between the heat medium and the inner shell 3.

[0049] As another optional implementation of this embodiment, since the inner shell 3 rotates relative to the guide assembly during operation, the coaxiality between the inner shell 3 and the guide assembly is improved. A positioning section 45 may be provided at the end of the inflow section 41 away from the guide section 42, and a positioning groove for accommodating the positioning section 45 is provided on the inner end surface of the heat medium cavity 31, thereby avoiding misalignment between the inner shell 3 and the guide assembly.

[0050] like Figure 4 and Figure 5As shown, in this embodiment, each scraper assembly includes a plurality of movable scrapers 5, and the plurality of movable scrapers 5 in the same scraper assembly are arranged along the axial direction of the inner shell 3, and a scraper gap is provided between any two adjacent movable scrapers 5, and the movable scrapers 5 in different scraper assemblies are arranged in a staggered manner. When the inner shell 3 rotates, the plurality of movable scrapers 5 in the scraper assembly will scrape the inner wall of the material cavity 21, so that the crystals generated on the inner wall of the material cavity 21 are separated from the outer shell 2. Since a scraper gap is provided between any two adjacent movable scrapers 5 in the same scraper assembly, and the movable scrapers 5 in different scraper assemblies are arranged in a staggered manner, the plurality of movable scrapers 5 can completely scrape the inner wall of the material cavity 21 during the rotation of the inner shell 2, thereby avoiding the occurrence of a scraping blind area on the inner wall of the material cavity 21.

[0051] Optionally, in order to realize the assembly between the movable scraper 5 and the inner shell 3, a plurality of assembly cut surfaces 32 for mounting the movable scraper 5 are provided on the outer side wall of the inner shell 3. Figure 5 As shown, a limiting column 33 and a positioning column 34 are provided on the assembly section 32, wherein a limiting groove 331 is provided on the side wall of the limiting column 33 close to the positioning column 34, a blade 51 is provided at one end of the movable scraper 5, and a positioning hole 52 for accommodating the positioning column 34 is also provided on the movable scraper 5.

[0052] During assembly, the staff can insert the end of the movable scraper 5 away from the blade 51 into the limiting groove 331, and insert the positioning column 34 into the positioning hole 52, so that the movable scraper 5 is installed on the inner shell 3. Since the movable scraper 5 needs to bear stress in the process of scraping off the crystal, a movable gap should be formed between the inner wall of the limiting groove 331 and the movable scraper 5, and the inner diameter of the positioning hole 52 should be larger than the outer diameter of the positioning column 34. When the movable scraper 5 contacts the crystal, the end of the movable scraper 5 with the blade 51 will be deflected away from the inner shell 3, which can not only protect the movable scraper 5, but also increase the shearing force of the blade 51 on the crystal, thereby improving the efficiency of crystal shedding.

[0053] In addition, in order to reduce the resistance of the movable scraper 5 during the rotation of the inner shell 3, a drainage cutout 53 can be provided at one end of the movable scraper 5 away from the blade 51. When the inner shell 3 rotates, the drainage cutout 53 allows the liquid material in the material cavity 21 to pass through, thereby protecting the movable scraper 5.

[0054] As another optional implementation of this embodiment, in order to improve the assembly reliability of the movable scraper 5, two limit columns 33 and two positioning columns 34 can be provided on each assembly section 32, and the distance between the two limit columns 33 should be smaller than the distance between the two positioning columns 34, so that the end of the movable scraper 5 with the blade 51 has good stability after being deflected away from the inner shell body 3.

[0055] The effects of the above scheme are described below:

[0056] This embodiment provides a continuous production device for cooling and crystallizing organic matter, and a cold medium cavity and a hot medium cavity are provided inside the pre-crystallizer, so that the staff can adjust the seed content by adjusting the temperature and flow rate of the cold and hot media, so that the turbidity of the material entering the granulation equipment meets the actual needs. Secondly, the movable scraper in the pre-crystallizer can be deflected during the operation and can be heated by the hot medium, so as to protect the movable scraper and avoid the material sticking on the movable scraper, so that the device can carry out long-term continuous production. In addition, the pre-crystallizer can also improve the heat exchange effect between the hot medium and the inner shell through the guide component, so as to facilitate the timely transfer of heat to the scraper wall component.

[0057] It should be noted that, in order to prevent leakage of the material cavity 21 and the heat medium cavity 31, the pre-crystallizer 13 should also be provided with a rotating seal at the connection gap between the outer shell 2, the inner shell 3 and the guide assembly to enhance the sealing of the pre-crystallizer. Since the structure and use of the rotating seal are already well known to those skilled in the art, the relevant content will not be repeated in this application.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
