Description

Technical Field

[0001] This utility model relates to the field of granulation and drying technology, specifically to a centrifugal spray granulation and drying device with an anti-clogging structure. Background Technology

[0002] Centrifugal spray granulation and drying equipment is an advanced process equipment that integrates granulation and drying. It is mainly used to transform liquid raw materials or suspensions into dry particles or powders. Its core principle is to generate a fine mist spray under the action of centrifugal force, and at the same time achieve the drying process through hot air or hot airflow.

[0003] Patent CN211800648U discloses a spray granulation drying device, including a housing. Utilizing the characteristic that granules shrink in size after evaporating moisture, a sieve plate is used to discharge granules that have reached the required moisture content. Granules that do not meet the moisture standard remain on the sieve plate for further heating, ensuring that each granule has a standardized and uniform dryness. A central shaft stirs the granules on the sieve plate, ensuring even granule distribution and preventing clogging. A brush plate rotates with the central shaft, using a sponge to absorb water vapor adhering to the inner wall of the housing top, preventing condensation and water droplets from falling onto the sieve plate and affecting the drying effect. A turntable continuously vibrates the housing during the rotation of the central shaft, further preventing clogging and accelerating the discharge of granules accumulated at the bottom of the housing.

[0004] Based on existing solutions and actual use, current centrifugal spray granulation and drying equipment still has some problems. For example, when the equipment is running for a long time, the nozzles or spray heads are easily blocked by solid particles, sediments or crystals. Because the nozzles are blocked, they cannot work properly, resulting in uneven spraying or interruption. This can easily lead to quality problems such as inconsistent particle size, agglomeration, and poor crystallization, which in turn affects production efficiency and product quality. Utility Model Content

[0005] The purpose of this utility model is to provide a centrifugal spray granulation and drying device with an anti-clogging structure, so as to solve the problem mentioned in the background art that the nozzle or spray head is easily blocked by solid particles, precipitates or crystals during long-term operation, which leads to the inability to work properly due to nozzle blockage, resulting in quality problems such as inconsistent particle size, agglomeration, and poor crystallization.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal spray granulation and drying device with an anti-clogging structure, comprising:

[0007] The base has a drying tower fixedly installed at its right end and a separator fixedly installed at its left end. A spray head is fixedly installed at the upper right end of the drying tower, and a filter chamber is fixedly installed at the lower right end of the drying tower. A filter assembly is installed inside the filter chamber. An regulating chamber is fixedly installed at the right end of the drying tower, and the top of the regulating chamber is connected to the spray head. A flow control assembly is installed inside the regulating chamber. A cleaning assembly is installed inside the drying tower.

[0008] Preferably, the filter assembly includes a mounting frame, filter elements, and connecting pipes, and the filter chamber is equipped with a conveniently replaceable mounting frame. The mounting frame has filter elements fixedly mounted in an array on its frame body. The top of the filter chamber is fixedly mounted with connecting pipes, and the pipe body is connected to the bottom of the adjustment chamber.

[0009] Preferably, the flow control assembly includes a baffle, a rotating rod, a gear, a sliding groove, a rack, and an electric push rod. The baffle is rotatably connected inside the regulating chamber. The rotating rod is rotatably connected to the right end of the regulating chamber. The left end of the rotating rod is connected to the right end of the baffle. The gear is fixedly installed on the right end of the rotating rod. A sliding groove is fixedly installed on the top of the right end of the regulating chamber. A rack is slidably connected inside the sliding groove, and the rack and gear mesh with each other. An electric push rod is fixedly installed on the right end of the sliding groove, and the output end of the electric push rod is connected to the front end of the rack.

[0010] Preferably, the diameter of the baffle is the same as the diameter of the inner cavity of the regulating chamber, and the baffle is attached to the inner wall of the regulating chamber by a sealing ring.

[0011] Preferably, the cleaning assembly includes a sliding rod, a scraper ring, a threaded rod, and a motor. The sliding rod is fixedly installed at the right end inside the drying tower, and the scraper ring is slidably connected to the body of the sliding rod. The threaded rod is rotatably connected to the left end inside the drying tower, and the motor is fixedly installed at the left end of the top of the drying tower. The output end of the motor is connected to the upper end of the threaded rod.

[0012] Preferably, the rod body of the threaded rod is connected to the scraper ring by threads, the diameter of the scraper ring is the same as the diameter of the inner cavity of the drying tower, and the side wall of the scraper ring is set in an inclined state.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This centrifugal spray granulation and drying equipment with an anti-clogging structure can block impurities, sediments or particles through the cooperation between the mounting frame and the filter element, thereby ensuring the smoothness of the spray path and reducing clogging and uneven spraying. Then, the flow rate and spray volume of the liquid can be adjusted by adjusting the baffle. By precisely controlling the flow rate, more uniform particle size and drying degree can be obtained. At the same time, the movement of the scraper ring can effectively remove the attached powder or particles, prevent agglomeration and accumulation of adhering materials on the wall surface, and reduce the clogging caused by wall adhesion through scraping, thereby ensuring a smooth drying process.

[0014] 1. The system is equipped with a drying tower, spray head, filter chamber, mounting frame, filter element, connecting pipe, and regulating chamber. The filter chamber contains a replaceable mounting frame with filter elements fixedly mounted in an array. These filter elements filter the liquid entering the filter chamber. The filter chamber is then connected to the regulating chamber via a connecting pipe at the top, and the regulating chamber is connected to the spray head. This allows the filtered liquid to be sprayed into the drying tower for reaction. The cooperation between the mounting frame and the filter element blocks impurities, sediments, or particles, ensuring a clear spray path, reducing clogging and uneven spraying, thus maintaining good spraying performance and improving quality stability.

[0015] 2. The system is equipped with an adjusting chamber, a baffle, a rotating rod, a gear, a sliding groove, a rack, and an electric push rod. The output end of the electric push rod drives the rack to slide inside the sliding groove. The rack and gear mesh with each other. Since the gear is fixedly installed on the right end of the rotating rod, the gear drives the rotating rod to rotate, which in turn drives the baffle to rotate inside the adjusting chamber. The diameter of the baffle matches the diameter of the inner cavity of the adjusting chamber, so the flow rate of the liquid can be adjusted by the rotation of the baffle inside the adjusting chamber. By adjusting the baffle, the flow rate and spray volume of the liquid can be adjusted. Through precise flow control, more uniform particle size and dryness can be obtained, thereby ensuring stable product quality.

[0016] 3. The system includes a drying tower, a sliding rod, a scraper ring, a threaded rod, and a motor. The threaded rod is connected to the scraper ring via threads, and the upper end of the threaded rod is connected to the output end of the motor. The motor's operation drives the threaded rod to rotate inside the drying tower. The scraper ring has the same diameter as the drying tower's inner cavity, and its sidewall is inclined. When the threaded rod rotates, it causes the scraper ring to rise and fall, sliding on the sliding rod. This movement of the scraper ring scrapes the sidewall of the drying tower, effectively removing adhering powder or particles and preventing agglomeration and material accumulation on the wall surface. This scraping reduces blockages caused by wall adhesion and ensures a smooth drying process. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a centrifugal spray granulation and drying device with an anti-clogging structure, comprising: a base 1, a drying tower 2, a separator 3, a spray head 4, a filter chamber 5, a mounting frame 6, a filter element 7, a connecting pipe 8, an adjusting chamber 9, a baffle 10, a rotating rod 11, a gear 12, a sliding groove 13, a rack 14, an electric push rod 15, a sliding rod 16, a scraper ring 17, a threaded rod 18, and a motor 19.

[0025] First, as attached Figure 1 Appendix Figure 3 and attached Figure 5As shown, when using the drying tower 2 to granulate the liquid, a filter chamber 5 is fixedly installed at the lower right end of the drying tower 2, connecting the liquid to the filter chamber 5. Simultaneously, an regulating chamber 9 is fixedly installed at the right end of the drying tower 2, with its upper end connected to the spray head 4. A connecting pipe 8 is fixedly installed at the top of the filter chamber 5, connecting it to the regulating chamber 9, thus creating communication between the filter chamber 5 and the regulating chamber 9. During the reaction drying of the liquid, the flow rate can be adjusted according to actual conditions. A baffle 10 is rotatably connected inside the regulating chamber 9, and a rotating rod 11 is rotatably connected inside the right end of the regulating chamber 9. The left end of the rotating rod 11 is fixedly connected to the baffle 10, and a gear 12 is fixedly installed at the right end of the rotating rod 11. A sliding groove 13 is fixedly installed at the top right end of the regulating chamber 9, and a rack 14 is slidably connected inside the sliding groove 13. The rack 14 meshes with the gear 12, and an electric push rod 15 is fixedly installed at the right end of the sliding groove 13. The output end of the electric push rod 15 is fixedly connected to the front end of the rack 14. The electric push rod 15 can be controlled by the controller to operate, and the operation of the electric push rod 15 can drive the rack 14 to slide inside the sliding groove 13. At the same time, the cooperation between the rack 14 and the gear 12 drives the rotating rod 11 to rotate, and the rotation of the rotating rod 11 drives the baffle 10 to rotate inside the regulating chamber 9. Since the diameter of the baffle 10 is the same as the diameter of the inner cavity of the regulating chamber 9, and the baffle 10 is set in a close fit with the regulating chamber 9 through the sealing ring, the extension and retraction of the electric push rod 15 can drive the baffle 10 to rotate to a suitable angle. The rotation of the baffle 10 can then adjust the flow rate of the liquid, and by precisely controlling the flow rate, a more uniform particle size and degree of dryness can be obtained.

[0026] As attached Figure 1 and attached Figure 4As shown, after the baffle 10 adjusts the flow rate of the liquid, it begins to deliver liquid into the filter chamber 5. Since the filter chamber 5 is equipped with a replaceable mounting bracket 6, and the mounting bracket 6 has filter elements 7 fixedly installed in an array, when the liquid enters the filter chamber 5, it is filtered through the cooperation between the mounting bracket 6 and the filter elements 7. Then, the filter chamber 5 is connected to the regulating chamber 9 through the connecting pipe 8, so that the filtered liquid enters the regulating chamber 9. The baffle 10 controls the flow rate of the liquid, and then it is sprayed into the drying tower 2 through the spray head 4, so that the liquid enters the drying tower 2. After passing through the liquid drying tower 2, it undergoes granulation and drying. Since the left end of the base 1 is fixedly installed with a separator 3, the processed particles enter the separator 3 and are centrally managed. By filtering the liquid, impurities, sediments or particles can be blocked, thereby ensuring the smoothness of the spray path and reducing clogging and uneven spraying.

[0027] As attached Figure 1 and attached Figure 2 As shown, after the drying tower 2 granulates and dries the liquid, the motor 19 can be controlled by the controller to operate. A sliding rod 16 is fixedly installed on the right end inside the drying tower 2, and a scraper ring 17 is slidably connected to the rod body of the sliding rod 16. At the same time, a threaded rod 18 is rotatably connected to the left end inside the drying tower 2, and the rod body of the threaded rod 18 is connected to the scraper ring 17 by threads. The upper end of the threaded rod 18 is connected to the output end of the motor 19. When the motor 19 is running, it can drive the threaded rod 18 to rotate inside the drying tower 2. The rotation of the threaded rod 18 can drive the scraper ring 17 to rise and fall, and make the scraper ring 17 slide on the rod body of the sliding rod 16. Since the diameter of the scraper ring 17 is the same as the diameter of the inner cavity of the drying tower 2, and the side wall of the scraper ring 17 is set in an inclined state, the rise and fall of the scraper ring 17 can scrape the inner side wall of the drying tower 2, so as to effectively remove the attached powder or particles and prevent the agglomeration and accumulation of adhering materials on the wall surface.
