Description

Technical Field

[0001] This invention relates to the field of spirocyclic compound production equipment technology, specifically to an integrated post-processing device for spirocyclic compounds. Background Technology

[0002] Spirocyclic compounds are a class of organic compounds with a unique bicyclic spirocyclic structure, possessing distinctive optical properties, chemical stability, and biological activity. They are widely used in pharmaceutical intermediates, optoelectronic materials, and fine chemicals. After the synthesis reaction of spirocyclic compounds, the crude product usually contains unreacted raw materials, byproducts, solvent impurities, and suspended particulate matter. A series of post-processing steps, such as washing and purification, solid-liquid separation, and drying, are required to obtain a high-purity finished product.

[0003] However, existing post-processing operations for spirocyclic compounds generally employ a multi-unit, separate operation mode, using independent washing equipment, solid-liquid separation equipment, and requiring manual transfer of materials between different devices. This results in a cumbersome overall process, high labor intensity, and low production efficiency. Furthermore, materials easily adhere to the filter screen surface, and if manual cleaning is not timely, it can directly clog the filter pores, further reducing separation efficiency and affecting product recovery rates. Secondly, the drying equipment directly dries the accumulated materials, resulting in uneven material thickness and difficulty for internal materials to come into contact with hot air, easily leading to a phenomenon where the surface is dried while the inside remains damp, resulting in inconsistent drying quality. Moreover, the single-direction hot air drying method has low heat utilization and high energy consumption. Therefore, we propose an integrated post-processing device for spirocyclic compounds. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated post-processing device for spirocyclic compounds, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated post-processing device for spirocyclic compounds, comprising a solid-liquid separation mechanism, a washing mechanism, and a drying mechanism; The solid-liquid separation mechanism includes a separation box, a through groove is provided on the front of the separation box, a sliding frame is slidably connected to the front of the separation box through the through groove, and a cleaning scraper is fixedly connected to the back of the sliding frame. The washing mechanism includes a washing tank bolted to the top of the separation box, and a stirring motor is installed at the center of the top of the separation box. The driving end of the stirring motor is fixed with a stirring rod through a coupling. The drying mechanism includes a conveyor frame installed on one side of the separation box. A drying hood is bolted to the top of the conveyor frame. A heating grid, a material spreading frame, and a material feeding frame are respectively installed on the inner side of the drying hood. A conveyor roller is rotatably connected to the inner side of the conveyor frame.

[0006] Preferably, a connecting pipe is inserted into one side of the separation box, a solenoid valve is threaded onto the outer side of the connecting pipe, the connecting pipe is inserted into the washing tank, and a drain pipe is threaded onto the other side of the separation box.

[0007] Preferably, a motor frame is welded to one side of the through groove on the front of the solid-liquid separation mechanism, a cleaning motor is installed on one side of the motor frame, a cleaning screw is fixed to the drive end of the cleaning motor through a coupling, a nut seat is threaded to the outer side of the cleaning screw, and the nut seat is bolted to the sliding frame.

[0008] Preferably, a coarse-pore filter, a medium-pore filter, and a micro-pore filter are installed sequentially from top to bottom on the inner side of the separation box. The coarse-pore filter, the medium-pore filter, and the micro-pore filter are all in contact with the cleaning scraper. The diameter of the micro-pore filter is smaller than that of the medium-pore filter, and the diameter of the medium-pore filter is smaller than that of the coarse-pore filter.

[0009] Preferably, a protective cover is installed on the outside of the washing tank, and a heating plate is installed inside the protective cover, with the heating plate being fitted and connected to the washing tank.

[0010] Preferably, the front of the separation box is threaded with a liquid filling pipe, and the top of the separation box is integrally formed with a feeding pipe.

[0011] Preferably, a drying fan is installed on the front of the drying hood, and an air supply pipe is installed on the top of the drying fan, the air supply pipe being bolted to the drying hood.

[0012] Preferably, a conveyor motor is installed at the bottom of the separation box, and a conveyor wheel is keyed to the drive end of the conveyor motor. A drive belt is driven to the outer side of the conveyor wheel.

[0013] Preferably, a conveyor belt is driven to the outer side of the conveying roller, and a drive wheel is keyed to one end of the conveying roller, the drive wheel being driven to the drive belt.

[0014] This invention provides an integrated post-processing device for spirocyclic compounds, which has the following advantages: 1. This integrated post-processing unit for spirocyclic compounds combines washing, solid-liquid separation, and drying into a single device. Materials can complete the entire processing process within the unit, eliminating the need for manual material transfer between different equipment. After being fed into the unit through the feed pipe, materials sequentially complete their respective processes in the washing tank, separation chamber, and drying hood. No manual handling or connection is required throughout the entire process, resulting in a streamlined and efficient workflow that simplifies production. Furthermore, the entire system can operate continuously for extended periods, completely resolving the issues of fragmented processes and discontinuous production associated with separate equipment. This significantly improves the overall production efficiency of spirocyclic compound post-processing and makes it suitable for large-scale industrial production.

[0015] 2. This integrated post-treatment device for spirocyclic compounds comprises an automatic unclogging structure consisting of a motor frame, a cleaning motor, a cleaning screw, a nut seat, a sliding frame, and a cleaning scraper. When residual material adheres to the filter screen surface, the cleaning motor drives the cleaning screw to rotate, causing the nut seat and sliding frame to slide back and forth along the through groove. The cleaning scraper moves closely against the surface of the three-layer filter screen, automatically scraping off the solid material adhering to the filter screen. This ensures continuous unobstructed filter screen pores, preventing filter screen blockage and separation interruption, and also scrapes all residual material onto the conveyor belt, further reducing material residue loss. No manual shutdown for filter screen cleaning is required, reducing labor intensity. Waste liquid generated during separation can be discharged uniformly through a drain pipe, resulting in neat waste liquid collection and a cleaner workshop environment.

[0016] 3. This integrated post-processing device for spirocyclic compounds integrates a material spreading rack, a material handling rack, a heating grid, and supporting drying fans and air supply pipes inside the drying hood. The material spreading rack evenly spreads the accumulated material, maintaining a consistent material thickness. The material handling rack continuously turns the material during conveying, ensuring all parts of the material are fully exposed to hot air. The airflow generated by the drying fan is delivered into the drying hood through the air supply pipes, and the airflow passes through the heating grid to form stable hot air, drying the dynamically conveyed and constantly turning material from all angles. This structure solves the problems of material accumulation, uneven drying, and external dryness with internal moisture, resulting in stable drying quality. The enclosed structure reduces hot air loss, saving energy and improving efficiency. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-9 The present invention provides a technical solution: an integrated device for post-processing of spirocyclic compounds, comprising a solid-liquid separation mechanism 1, a washing mechanism 2, and a drying mechanism 3; The solid-liquid separation mechanism 1 includes a separation box 101. A through groove 108 is provided on the front of the separation box 101. A sliding frame 109 is slidably connected to the front of the separation box 101 through the through groove 108. A cleaning scraper 110 is fixedly connected to the back of the sliding frame 109. The washing mechanism 2 includes a washing tank 201 bolted to the top of the separation box 101. An agitator motor 206 is installed at the center of the top of the separation box 101. An agitator rod 207 is fixed to the drive end of the agitator motor 206 via a coupling. The drying mechanism 3 includes a conveyor frame 301 installed on one side of the separation box 101. A drying hood 302 is bolted to the top of the conveyor frame 301. A heating grid 305, a material spreading frame 306, and a material feeding frame 307 are respectively installed on the inner side of the drying hood 302. A conveyor roller 311 is rotatably connected to the inner side of the conveyor frame 301.

[0021] Furthermore, a connecting pipe 102 is inserted into one side of the separation box 101, and a solenoid valve 103 is threaded onto the outer side of the connecting pipe 102. The connecting pipe 102 is connected to the washing tank 201. A drain pipe 114 is threaded onto the other side of the separation box 101. The opening and closing of the connecting pipe 102 can be controlled by the solenoid valve 103, so that the solid-liquid mixture in the washing tank 201 flows into the separation box 101 in a directional manner, and the waste liquid generated by the separation can be discharged outwards through the drain pipe 114.

[0022] Furthermore, a motor frame 104 is welded to one side of the through groove 108 on the front of the solid-liquid separation mechanism 1. A cleaning motor 105 is installed on one side of the motor frame 104. A cleaning screw 106 is fixed to the drive end of the cleaning motor 105 through a coupling. A nut seat 107 is threaded to the outer side of the cleaning screw 106. The nut seat 107 is bolted to the sliding frame 109. After the cleaning motor 105 is started, the cleaning screw 106 rotates synchronously, driving the nut seat 107 and the sliding frame 109 to reciprocate linearly along the through groove 108, providing power support for cleaning the filter screen.

[0023] Furthermore, from top to bottom, the inner side of the separation box 101 is equipped with a coarse-pore filter 111, a medium-pore filter 112, and a micro-pore filter 113. The coarse-pore filter 111, the medium-pore filter 112, and the micro-pore filter 113 are all in close contact with the cleaning scraper 110. The diameter of the micro-pore filter 113 is smaller than that of the medium-pore filter 112, and the diameter of the medium-pore filter 112 is smaller than that of the coarse-pore filter 111. The three layers of filters with different pore sizes can achieve graded solid-liquid separation. The cleaning scraper 110, which is in close contact with the filter, can move with the sliding frame 109 to scrape off the residual material attached to the surface of each filter and avoid clogging of the filter holes.

[0024] Furthermore, a protective cover 203 is installed on the outside of the washing tank 201, and a heating plate 204 is installed inside the protective cover 203. The heating plate 204 is attached to the washing tank 201. The protective cover 203 can protect the heating plate 204. The attached heating plate 204 can keep the washing tank 201 at a constant temperature, thereby improving the washing and impurity removal effect of the material.

[0025] Furthermore, the front of the separation box 101 is threaded with a liquid filling pipe 202, and the top of the separation box 101 is integrally formed with a feeding pipe 205. The feeding pipe 205 is used to feed the spirocyclic compound coarse material into the device. The liquid filling pipe 202 can add washing liquid, clean water and other process liquids into the washing tank 201 and the separation box 101 as needed, making disassembly and maintenance convenient.

[0026] Furthermore, a drying fan 303 is installed on the front of the drying hood 302, and an air supply pipe 304 is installed on the top of the drying fan 303. The air supply pipe 304 is bolted to the drying hood 302. The airflow generated by the drying fan 303 is stably delivered into the interior of the drying hood 302 through the air supply pipe 304. The bolted connection structure facilitates the disassembly and maintenance of the fan and pipes in the future.

[0027] Furthermore, a conveyor motor 308 is installed at the bottom of the separation box 101. The drive end of the conveyor motor 308 is keyed to a conveyor wheel 309. A transmission belt 310 is driven to the outside of the conveyor wheel 309. When the conveyor motor 308 is started, the conveyor wheel 309 can be driven to rotate synchronously. Power is transmitted outward by the transmission belt 310, thus completing the power input of the entire conveying structure.

[0028] Furthermore, a conveyor belt 313 is connected to the outer side of the conveying roller 311, and a drive wheel 312 is keyed to one end of the conveying roller 311. The drive wheel 312 is connected to the drive belt 310, and the drive belt 310 drives the drive wheel 312 and the conveying roller 311 to rotate, thereby driving the conveyor belt 313 to run at a uniform speed to complete the continuous conveying operation of the material after solid-liquid separation.

[0029] Working principle: When using the integrated post-processing device for spirocyclic compounds, the operator feeds the crude spirocyclic compound material into the washing tank 201 through the feeding pipe 205, and then adds washing liquid, pure water, or process-required regulators into the washing tank 201 through the liquid adding pipe 202. After the material and washing liquid are added, the stirring motor 206 is started. The stirring motor 206 drives the stirring rod 207 to rotate, thoroughly stirring and mixing the material and liquid in the tank, washing away any unreacted raw materials, soluble by-products, and various impurities remaining in the material.

[0030] During the agitation and washing process, the heating plate 204 inside the protective cover 203 works simultaneously to heat the washing tank 201 at a constant temperature, maintaining the temperature between 40℃ and 50℃, thereby improving the washing and impurity removal effect. After the washing process is completed, the solenoid valve 103 outside the connecting pipe 102 is opened, and the washed solid-liquid mixture flows into the separation box 101 through the connecting pipe 102.

[0031] After the mixture enters the separation tank 101, it passes through the coarse-pore filter 111, medium-pore filter 112, and micro-pore filter 113 arranged from top to bottom in the tank to complete the staged solid-liquid separation. The solid spirocyclic compounds are intercepted by the three layers of filter screens, while the waste liquid containing impurities passes through the filter screens and falls to the bottom of the separation tank 101, and is finally discharged to the outside through the drain pipe 114.

[0032] During the separation process, the solid material on the filter screen will gradually slide down to the surface of the conveyor belt 313 on one side of the conveyor frame 301. If there is material residue on the filter screen surface and it cannot slide down naturally, the cleaning motor 105 is started. The cleaning motor 105 drives the cleaning screw 106 to rotate, which drives the matching nut seat 107 and the sliding frame 109 to move back and forth in a straight line along the through groove 108. The cleaning scraper 110 on the back of the sliding frame 109 moves in sync with the surface of the three layers of filter screen, scraping all the attached solid material onto the conveyor belt 313, ensuring that the filter screen is unobstructed and the material is completely collected.

[0033] At the same time, the conveyor motor 308 installed at the bottom of the separation box 101 starts to run, and drives the transmission belt 310 through the conveyor wheel 309. The transmission belt 310 then drives the transmission wheel 312 and the conveyor roller 311 to rotate, thereby driving the conveyor belt 313 to rotate at a constant speed and conveying the solid material into the drying hood 302.

[0034] After the material enters the drying hood 302, the spreading rack 306 flattens and arranges the accumulated material, controlling the thickness of the material spread; the material tampering rack 307 continuously turns the material to ensure uniform drying. The drying fan 303 generates airflow in the working state, which is sent into the interior of the drying hood 302 through the air supply pipe 304. After the airflow passes through the heating grid 305, it forms high-temperature hot air, which dries the moving material.

[0035] After the entire process is completed, the dried spirocyclic compound product is moved out of the drying area by conveyor belt 313, and the staff can collect the finished product in a centralized manner, thus completing the entire set of post-processing operations for the spirocyclic compound.

[0036] 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 within the protection scope of the present invention.
