Description

Technical Field

[0001] This utility model belongs to the field of crystallizer technology, specifically relating to a high-efficiency crystallizer for the crystallization and purification of organic matter. Background Technology

[0002] A crystallizer is a trough-shaped container with a jacket on the wall or a coil inside, used to heat or cool the solution within. The crystallizer can be used as an evaporative crystallizer or a cooling crystallizer. It can be used for continuous or batch operation. Batch operation produces larger crystals, but these crystals tend to cluster together, carrying mother liquor and affecting product purity. This type of crystallizer has a simple structure and low production intensity, making it suitable for small-batch production of products (such as chemical reagents and biochemical reagents).

[0003] In the existing technology for preparing and purifying 2,4-dinitrochlorobenzene, the high-efficiency crystallizer filters the 2,4-dinitrochlorobenzene solution. However, impurities inside the solution clog the filter screen, which can affect the subsequent filtration effect. Furthermore, the filter screen is fixed inside the filtration chamber, making it difficult to clean. The condensate from the heater and condenser outlets is directly discharged into the external environment, which can cause the surrounding environment to become slippery and waste water resources. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a high-efficiency crystallizer for the crystallization and purification of organic matter, characterized by easy disassembly, cleaning, and collection of dripping water.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency crystallizer for the crystallization and purification of organic matter, comprising a crystallization mechanism, a condenser provided at one upper end of the crystallization mechanism, a crystallization discharge mechanism provided on the side wall of the crystallization mechanism, a heater provided at the lower part of the crystallization mechanism, condensate outlets fixedly connected to the side walls of the condenser and the heater, a collection assembly provided on the side walls of the condenser and the heater and located below the condensate outlets, a filter chamber provided on one side of the heater, a filter screen provided inside the filter chamber, and an installation assembly provided between the filter chamber and the filter screen;

[0006] The installation assembly includes an end plate, a fastener is provided between the filter chamber and the end plate, an installation port is provided on the side wall of the filter chamber at the position corresponding to the end plate, an external frame is fixedly connected to the side wall of the end plate and located around the filter screen, and an internal U-shaped frame is fixedly connected to the inner side wall of the filter chamber and located around the external frame.

[0007] Preferably, the fastener includes a threaded post, a collar is sleeved on the outer side wall of the threaded post, a fixing nut is threadedly connected to the outer side wall of the threaded post on the side of the collar away from the filter chamber, a fixing rod is fixedly connected to the side wall of the collar, a fixing post is fixedly connected to the side wall of the fixing rod, and a fixing block is fixedly connected to the side wall of the end plate at the position corresponding to the fixing post.

[0008] Preferably, a sealing ring is fixedly connected to the side of the end plate near the mounting port.

[0009] Preferably, a limiting disk is fixedly connected to the end of the threaded column away from the filter chamber, and the threaded column and the limiting disk are an integral structure.

[0010] Preferably, the collection assembly includes a collection box, and side plates are fixedly connected to the side walls of the condenser and heater on both sides of the collection box.

[0011] Preferably, movable sleeves are fixedly connected to both sides of the collection box, and plug rods are slidably connected inside the movable sleeves. A connecting spring is fixedly connected between the plug rods and the collection box and inside the movable sleeves. Plug holes are provided on the side plates at positions corresponding to the plug rods.

[0012] Preferably, the plug rod is fixedly connected to limit sliders on both sides of the end near the movable sleeve, and a limit groove is formed on the inner side wall of the movable sleeve at the position corresponding to the limit slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model is equipped with an installation component. The end plate is moved and inserted into the installation port. The movement of the end plate drives the outer frame to move and insert into the inner U-shaped frame, thereby allowing the filter screen to be installed inside the filter chamber. Then, the collar is rotated, which drives the fixing rod to rotate to the periphery of the end plate. Then, the fixing nut is rotated, causing it to rotate and move along the threaded column. The rotation and movement of the fixing nut pushes the collar to move, which drives the fixing rod to move. The movement of the fixing rod drives the fixing column to move. When the fixing column moves and inserts into the inside of the fixing block, the rotation of the fixing nut is stopped, which facilitates the disassembly and assembly of the filter screen, and thus facilitates the cleaning of the filter screen.

[0015] 2. This utility model is equipped with a collection component. The insertion rod moves into the movable sleeve, and the moving insertion rod compresses the connecting spring. Then, the collection box is placed between the two side plates. Then, the insertion rod is released, and the connecting spring returns to its original state after losing external force. This causes the insertion rod to move and insert into the insertion hole, which facilitates the disassembly and assembly of the collection box. The condensate discharged from the condensate outlet falls into the collection box for collection, preventing the condensate from falling into the surrounding environment and causing the surrounding environment to become slippery. The collected condensate can also be reused, avoiding the waste of condensate resources. Attached Figure Description

[0022] 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.

[0023] Example 1:

[0024] Please see Figure 1-5 The present invention provides the following technical solution: a high-efficiency crystallizer for the crystallization and purification of organic matter, comprising a crystallization mechanism 5, a condenser 1 provided at the upper end of the crystallization mechanism 5, a crystallization discharge mechanism 2 provided on the side wall of the crystallization mechanism 5, a heater 4 provided at the lower end of the crystallization mechanism 5, a condensate outlet 7 fixedly connected to the side wall of both the condenser 1 and the heater 4, a collection assembly 6 provided on the side wall of both the condenser 1 and the heater 4 and located below the condensate outlet 7, a filter chamber 3 provided on one side of the heater 4, a filter screen 9 provided inside the filter chamber 3, and an installation assembly 8 provided between the filter chamber 3 and the filter screen 9;

[0025] The mounting assembly 8 includes an end plate 81, a fastener 83 is provided between the filter chamber 3 and the end plate 81, an installation port 82 is provided on the side wall of the filter chamber 3 at the position corresponding to the end plate 81, an outer frame 85 is fixedly connected to the side wall of the end plate 81 and located around the filter screen 9, and an inner U-shaped frame 84 is fixedly connected to the inner side wall of the filter chamber 3 and located around the outer frame 85.

[0026] Specifically, the fastener 83 includes a threaded post 835, a collar 836 fitted onto the outer wall of the threaded post 835, a fixing nut 834 threadedly connected to the outer wall of the threaded post 835 on the side of the collar 836 away from the filter chamber 3, a fixing rod 833 fixedly connected to the side wall of the collar 836, a fixing post 832 fixedly connected to the side wall of the fixing rod 833, and a fixing block 831 fixedly connected to the side wall of the end plate 81 at the position corresponding to the fixing post 832.

[0027] By adopting the above technical solution, after the end plate 81 is moved and inserted into the mounting port 82, the collar 836 is rotated. The rotation of the collar 836 drives the fixing rod 833 to rotate to the periphery of the end plate 81. Then, the fixing nut 834 is rotated, causing it to rotate and move along the threaded post 835. The rotation and movement of the fixing nut 834 pushes the collar 836 to move. The movement of the collar 836 drives the fixing rod 833 to move. The movement of the fixing rod 833 drives the fixing post 832 to move. When the fixing post 832 moves and is inserted into the fixing block 831, the rotation of the fixing nut 834 is stopped. By using the cooperation of the fixing post 832 and the fixing block 831, the end plate 81 can be inserted and fixed, ensuring the stability of the insertion of the end plate 81.

[0028] Specifically, a sealing ring is fixedly connected to the side of end plate 81 near the mounting port 82.

[0029] By adopting the above technical solution, after the end plate 81 is moved and inserted into the mounting port 82, the sealing ring then fits against the side wall of the mounting port 82. Under the action of the sealing ring, gaps between the end plate 81 and the mounting port 82 can be avoided, thereby preventing the leakage of the liquid to be purified.

[0030] Specifically, a limiting disc is fixedly connected to the end of the threaded column 835 away from the filter chamber 3. The threaded column 835 and the limiting disc are an integral structure.

[0031] By adopting the above technical solution, the fixing nut 834 is rotated and moved along the threaded post 835. When the fixing nut 834 moves and fits against the side wall of the limiting plate, the fixing nut 834 is blocked and stops moving, thus preventing the fixing nut 834 from disengaging from the threaded post 835.

[0032] In this embodiment, the end plate 81 is moved and inserted into the mounting port 82. The movement of the end plate 81 causes the outer frame 85 to move and be inserted into the inner U-shaped frame 84, thereby allowing the filter screen 9 to be installed inside the filter chamber 3. Then, the collar 836 is rotated, causing the fixing rod 833 to rotate to the periphery of the end plate 81. Next, the fixing nut 834 is rotated, causing it to rotate and move along the threaded post 835. The rotation and movement of the fixing nut 834 pushes the collar 836 to move, which in turn causes the fixing rod 833 to move. The movement of the fixing rod 833 causes the fixing post 832 to move. When the fixing post 832 is inserted into the fixing block 831, the rotation and fixing are stopped. Nut 834 facilitates the disassembly and assembly of filter screen 9, thereby facilitating the cleaning of filter screen 9. Organic liquid to be purified is then injected into filter chamber 3 through the feed inlet on filter chamber 3, and impurities in the liquid to be purified are filtered out by filter screen 9 in filter chamber 3. The filtered liquid to be purified is then transported through a pipeline to heater 4 for heating treatment, and then transported through a pipeline to crystallization mechanism 5 for processing. Finally, the gas inside crystallization mechanism 5 enters condenser 1 through a pipeline, and then the liquid at the bottom of crystallization mechanism 5 is discharged through a pipeline and crystallized using crystallization discharge mechanism 2. The condensate generated during the operation of heater 4 and condenser 1 is discharged through condensate outlet 7.

[0033] Example 2:

[0034] The difference between this embodiment and Embodiment 1 is that the collection assembly 6 includes a collection box 61, and side plates 62 are fixedly connected to the side walls of the condenser 1 and the heater 4 on both sides of the collection box 61.

[0035] Specifically, movable sleeves 66 are fixedly connected to both sides of the collection box 61. A plug-in rod 63 is slidably connected inside the movable sleeve 66. A connecting spring 65 is fixedly connected between the plug-in rod 63 and the collection box 61, located inside the movable sleeve 66. A plug-in hole 64 is provided on the side plate 62 at the position corresponding to the plug-in rod 63.

[0036] By adopting the above technical solution, the insertion rod 63 is moved into the movable sleeve 66, the insertion rod 63 moves and squeezes the connecting spring 65, and then the collection box 61 is placed between the two side plates 62. Then the insertion rod 63 is released, the connecting spring 65 loses the external force and returns to its original state, driving the insertion rod 63 to move and insert into the insertion hole 64, which facilitates the disassembly and assembly of the collection box 61.

[0037] Specifically, limit sliders are fixedly connected to both sides of the end of the plug rod 63 near the movable sleeve 66, and limit grooves are formed on the inner side wall of the movable sleeve 66 at the positions corresponding to the limit sliders.

[0038] By adopting the above technical solution, the insertion rod 63 moves and drives the limiting slider to move inside the limiting groove. Under the sliding cooperation of the limiting slider and the limiting groove, the movement of the insertion rod 63 can be guided. When the limiting slider moves and fits against the inner wall of the limiting groove, the limiting slider is blocked and stops moving, thereby preventing the insertion rod 63 from continuing to move and avoiding the insertion rod 63 from disengaging from the moving sleeve 66.

[0039] In this embodiment, the insertion rod 63 is moved into the movable sleeve 66, and the insertion rod 63 moves to compress the connecting spring 65. Then, the collection box 61 is placed between the two side plates 62. Then, the insertion rod 63 is released, and the connecting spring 65 returns to its original state after losing external force, driving the insertion rod 63 to move and insert into the insertion hole 64, which facilitates the disassembly and assembly of the collection box 61. The condensate discharged from the condensate outlet 7 falls into the collection box 61 for collection, preventing the condensate from falling into the surrounding environment and causing the surrounding environment to be slippery. The collected condensate can also be reused, avoiding the waste of condensate resources.

[0040] The structure and principle of the crystallization discharge mechanism 2, which consists of an output pipe and a No. 1 water pump, in this utility model have been disclosed in a high-efficiency crystallizer for the preparation and purification of 2,4-dinitrochlorobenzene, disclosed in Chinese patent application No. 202221812176.3. Its working principle is as follows: a No. 1 water pump is provided on one side of the crystallization mechanism 5, and an output pipe is connected between the No. 1 water pump and the crystallization mechanism 5. When in use, the No. 1 water pump is started, and under the action of the No. 1 water pump, the liquid at the bottom of the crystallization mechanism 5 is discharged from the output pipe and crystallizes.

[0041] The structure and principle of the crystallization mechanism 5, which consists of a crystallizer body, a cylindrical baffle, a guide tube, a propeller, and a sifting column, have been disclosed in Chinese patent application No. 202221812176.3, which describes a high-efficiency crystallizer for the preparation and purification of 2,4-dinitrochlorobenzene. Its working principle is as follows: A crystallizer body is set above the heater 4, a cylindrical baffle is set inside the crystallizer body, a guide tube is set inside the cylindrical baffle, a propeller is installed at the bottom of the guide tube, and a sifting column is set at the bottom of the crystallizer body. In use, the liquid to be purified after being heated by the heater 4 is transported to the inside of the crystallizer body through a pipeline, and then the propeller is started to drive the slurry to flow for processing.

[0042] The working principle and usage process of this utility model are as follows: The end plate 81 is moved and inserted into the mounting port 82. The movement of the end plate 81 drives the outer frame 85 to move and insert into the inner U-shaped frame 84, thus allowing the filter screen 9 to be installed inside the filter chamber 3. Then, the collar 836 is rotated, causing the fixing rod 833 to rotate to the periphery of the end plate 81. Next, the fixing nut 834 is rotated, causing it to rotate and move along the threaded post 835. The rotating and moving fixing nut 834 pushes the collar 836 to move, which in turn drives the fixing rod 833 to move. The moving fixing rod 833 then drives the fixing post 832 to move. When the fixing post 832 is inserted into the fixing block 831, the rotation of the fixing nut 834 is stopped, facilitating the disassembly and assembly of the filter screen 9, and thus facilitating the cleaning of the filter screen 9. The insertion rod 63 is moved into the moving sleeve 66, pressing the connecting spring 65. The collection box 61 is then placed between the two side plates 62, and then the release mechanism is activated. When the spring 65 loses its external force, the plug rod 63 returns to its original position, causing the plug rod 63 to move and insert into the plug hole 64, facilitating the disassembly and assembly of the collection box 61. The organic liquid to be purified is then injected into the filter chamber 3 through the inlet, and impurities are filtered out by the filter screen 9 inside the filter chamber 3. The filtered liquid is then transported through a pipeline to the heater 4 for heating, and then through another pipeline to the crystallization mechanism 5 for further processing. Finally, the gas inside the crystallization mechanism 5 enters the condenser 1 through a pipeline, and the liquid at the bottom of the crystallization mechanism 5 is discharged through the pipeline and crystallized using the crystallization discharge mechanism 2. The condensate generated during the operation of the heater 4 and the condenser 1 is discharged through the condensate outlet 7. The condensate discharged from the condensate outlet 7 falls into the collection box 61 for collection, preventing the condensate from falling into the surrounding environment and causing it to become slippery. The collected condensate can also be reused, avoiding waste of condensate resources.
