Description

Technical Field

[0001] This utility model relates to the technical field of spray drying equipment, and specifically discloses a high-efficiency spray drying equipment. Background Technology

[0002] Spray drying technology atomizes liquid materials into fine droplets and brings them into contact with hot air to achieve rapid drying and obtain solid powder. It is widely used in chemical, food, pharmaceutical, environmental protection and other industrial fields.

[0003] Chinese Patent No. CN220588953U discloses a high-efficiency spray drying device. In operation, a blower is first started to heat air entering the hot air inlet pipe before it is delivered to the drying tower. Then, motor number one is turned on, and raw materials are poured into a high-speed centrifugal atomizer through the liquid inlet pipe. The atomizer atomizes and spirals the raw materials, while hot air from the hot air inlet pipe dries them. Simultaneously, motor number two is started to rotate forward, causing the rotating part of the motor to drive the gear at the upper end of the rotating shaft. Because the gear meshes with the tooth groove, it drives the rotating sleeve to rotate. This causes the annular sliding strip fixed to the outer surface of the drying tower to slide within the annular groove on the inner surface of the rotating sleeve, thereby causing the striking block fixed to its lower end to rotate clockwise within the vibration chamber, impacting the surface of the vibrating block. Then, motor number two reverses, causing the striking block to rotate counterclockwise within the vibration chamber, impacting the other side of the vibrating block. This repeated motion prevents the dried finished particles from adhering to the bottom, thus avoiding the sticky particles that, over time, become defective and easily mix with qualified products, causing contamination.

[0004] 1. The shortcomings of the above-mentioned high-efficiency spray drying equipment are: the hot air system (blower, hot air inlet pipe) is not equipped with a filter device, and impurities such as dust, oil, and microorganisms in the ambient air directly enter the drying tower, affecting product quality;

[0005] 2. When the above device is in use, hot air will be discharged from the discharge pipe. The dried particles are easily carried by the hot air to the bottom of the drying tower. A large amount of fine powder will be lost with the exhaust gas, resulting in a low material recovery rate.

[0006] Therefore, a high-efficiency spray drying equipment is needed to solve the above problems. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0029] Please see Figure 1-5 A high-efficiency spray drying device includes a drying tower 2, a support 1 fixedly connected to the outer wall of the drying tower 2, a heating pipe 3 connected to the outer wall of the drying tower 2, a honeycomb electric heater 4 installed inside the heating pipe 3, a filter mechanism provided on the right side of the heating pipe 3, the filter mechanism including a frame 5 fixedly connected to the right end of the heating pipe 3 and having an open structure on the right side, a fixing frame 6 fixedly connected to the inner wall of the frame 5, a rectangular sealing gasket 7 installed on the right side of the fixing frame 6, a filling box 8 provided on the right side of the rectangular sealing gasket 7 and abutting against it and adapted to the inside of the fixing frame 6, the filling box 8 having an open structure on the upper side and being filled with activated carbon inside, a connecting frame 9 fixedly connected to the right end of the filling box 8, a connecting plate 10 fixedly connected to the right end of the connecting frame 9 and abutting against the right end of the frame 5, the connecting plate 10 and the frame 5 being detachably connected by several bolts;

[0030] A fan with an air outlet connected to the heating pipe 3 is installed on the left end of the inner wall of the frame 5;

[0031] A receiving mechanism is provided on the lower side of the drying tower 2. The receiving mechanism includes a discharge pipe 11 installed at the lower end of the drying tower 2. A support ring 12 is fixedly connected to the outer wall of the discharge pipe 11. An annular sealing gasket 13 is fixedly connected to the lower end of the support ring 12. A compression ring 14 that abuts against the annular sealing gasket 13 is threadedly connected to the outer wall of the discharge pipe 11. A filter cloth cylinder 15 is fixedly connected to the lower end of the compression ring 14.

[0032] A rotating spraying mechanism is installed above the discharge pipe 11.

[0033] In this embodiment: the filling box 8 is filled with activated carbon, and the rectangular sealing gasket 7 is tightly abutted against the left side of the filling box 8 and located on the outside of the supporting mesh plate, thereby providing a sealing effect. The connecting frame 9 is fixedly connected between the filling box 8 and the connecting plate 10, and the connecting frame 9 is located on the outside of the supporting mesh plate and the filter mesh plate. The connecting plate 10 and the frame 5 are connected and fixed by multiple bolts, thereby preventing air leakage.

[0034] The extrusion ring 14 is connected to the outer wall of the discharge pipe 11 by threads. The smooth surface at the upper end of the extrusion ring 14 will deform the annular sealing gasket 13 by extrusion, ensuring that the filter cloth cylinder 15 is sealed to the lower end of the discharge pipe 11.

[0035] During air filtration and heating, the fan at the left end of the inner wall of the frame 5 is started. The fan draws in ambient air from the opening on the right side of the frame 5. The air first passes through the filter screen on the outer wall of the connecting plate 10, and then enters the filling box 8 through the inside of the connecting frame 9 and the support screen on the right side. When the air passes through the activated carbon, dust, oil, microorganisms and other impurities are adsorbed, achieving deep purification. The purified air enters the heating tube 3 through the fan outlet. After the honeycomb electric heater 4 is powered on, it heats the air to the temperature required for drying. The heated air enters the drying tower 2 through the opening at the left end of the heating tube 3, providing hot airflow for material drying, thereby preventing impurities in the environment from entering the drying tower 2 and ensuring product quality.

[0036] The dried liquid material is then atomized and sprayed out by a rotary spraying mechanism. After the droplets diffuse into the interior of the drying tower 2, they come into full contact with the hot air. The hot air quickly removes the moisture from the droplets, forming dried particles. The dried particles settle to the bottom of the drying tower 2 due to gravity, while a small amount of fine powder continues to move downward with the airflow.

[0037] Larger dry particles settle directly to the bottom of the drying tower 2 and enter the filter cloth cylinder 15 through the discharge pipe 11. Fine powder carried by the airflow enters the filter cloth cylinder 15 and is intercepted by the fibers of the filter cloth cylinder 15. Meanwhile, the dry exhaust gas is discharged through the pores of the filter cloth cylinder 15, thus achieving solid-gas separation. In this way, it is possible to conveniently separate exhaust gas and fine powder, prevent fine powder from being lost with the exhaust gas, and improve the recovery efficiency.

[0038] When the activated carbon is saturated with adsorption, loosen the bolts between the connecting plate 10 and the frame 5, and pull the connecting plate 10 horizontally to the right, thereby causing the filling box 8 to detach from the inside of the frame 5, so that the activated carbon inside the filling box 8 can be replaced.

[0039] When it is necessary to remove the material inside the filter cloth cylinder 15, rotate the compression ring 14 to remove it, thereby facilitating the removal of the material inside the filter cloth cylinder 15.

[0040] As a technical optimization of this utility model, the rotary spray mechanism includes a sealed bearing 17 that is fixedly connected to the upper end of the drying tower 2. A spray pipe 18 extending into the interior of the drying tower 2 is fixedly connected inside the sealed bearing 17. Multiple atomizing nozzles 19 are connected to the outer wall of the spray pipe 18. A circular cover 22 is fixedly connected to the upper end of the drying tower 2. A sealed rotary joint 23 is fixedly connected to the upper end of the circular cover 22. The rotating end of the sealed rotary joint 23 is connected to the spray pipe 18. An L-shaped plate is fixedly connected to the upper end of the circular cover 22. A booster pump 24 with a discharge port connected to the fixed end of the sealed rotary joint 23 is installed at the upper end of the L-shaped plate. A gear ring 25 is fixedly connected to the outer wall of the spray pipe 18. A shaft 27 is rotatably connected to the top of the inner wall of the circular cover 22. A gear 26 meshing with the gear ring 25 is fixedly connected to the lower end of the shaft 27. A drive motor with an output end fixedly connected to the shaft 27 is installed at the upper end of the circular cover 22.

[0041] In this embodiment: During material atomization and drying, the liquid material to be dried is pressurized by the booster pump 24, input through the fixed end of the sealed rotary joint 23, and enters the spray pipe 18 through the rotating end. At the same time, the drive motor is started, driving the shaft 27 to rotate. The gear 26 at the lower end of the shaft 27 meshes with the gear ring 25 on the outer wall of the spray pipe 18, driving the spray pipe 18 to rotate around the central axis of the drying tower 2. The rotating spray pipe 18 atomizes the material into fine droplets through multiple atomizing nozzles 19 on the outer wall. After the droplets diffuse into the interior of the drying tower 2, they come into full contact with the hot air. The hot air quickly removes the moisture from the droplets, forming dried particles. The dried particles settle to the bottom of the drying tower 2 due to gravity, and a small amount of fine powder continues to move downward with the airflow.

[0042] As a technical optimization of this utility model, a synchronizing rod is fixedly connected to the lower end of the spray pipe 18, and multiple connecting rods 20 are fixedly connected to the outer wall of the synchronizing rod. Multiple connecting rods 20 located on the same side form a group, and the other end of each group of connecting rods 20 is fixedly connected to a scraper 21 that fits against the inner wall of the drying tower 2.

[0043] In this embodiment: when the spray pipe 18 rotates, the lower synchronous rod drives the connecting rod 20 and the scraper 21 to rotate synchronously. The scraper 21 adheres to the inner wall of the drying tower 2 and continuously scrapes off the dry particles attached to the inner wall of the drying tower 2, so as to avoid the accumulation of materials on the wall surface.

[0044] As a technical optimization of this utility model, the left and right ends of the filling box 8 are both fixedly connected with a support mesh plate, and the outer wall of the connecting plate 10 is fixedly connected with a filter mesh plate.

[0045] In this embodiment: by setting two support mesh plates, the activated carbon inside the filling box 8 is supported, and air is allowed to enter and exit the interior of the filling box 8. By setting filter mesh plates, larger particulate impurities in the environment are intercepted.

[0046] As a technical optimization of this utility model, the lower end of the extrusion ring 14 is fixedly connected with a plurality of support strips 16 arranged in a circumferential array and fixedly connected to the filter cloth cylinder 15 by an adhesive.

[0047] In this embodiment: the support bars 16 are arranged in a circular array to support the filter cloth tube 15 to keep it open and prevent the cloth tube from collapsing and affecting the separation effect.

[0048] As a technical optimization of this utility model, the outer wall of the extrusion ring 14 is fixedly connected with multiple hand-operated rods.

[0049] In this embodiment, the hand-operated lever on the outer wall of the compression ring 14 is easy to rotate manually to adjust the distance between the compression ring 14 and the support ring 12, and the compression amount of the annular sealing gasket 13 ensures that the filter cloth cylinder 15 is installed securely.

[0050] As a technical optimization of this utility model, a reinforcing plate is fixedly connected between the frame 5 and the bracket 1.

[0051] In this embodiment, the frame 5 is supported and stabilized by setting a reinforcing plate.

[0052] The working principle and usage process of this utility model: The filling box 8 is filled with activated carbon. The rectangular sealing gasket 7 is tightly abutted against the left side of the filling box 8 and located on the outside of the supporting mesh plate, thereby providing a sealing effect. The connecting frame 9 is fixedly connected between the filling box 8 and the connecting plate 10, and the connecting frame 9 is located on the outside of the supporting mesh plate and the filter mesh plate. The connecting plate 10 and the frame 5 are connected and fixed by multiple bolts, thereby preventing air leakage.

[0053] The support bar 16 provides support for the filter cloth cylinder 15 to prevent the flexible filter cloth cylinder 15 from deforming. The extrusion ring 14 is connected to the outer wall of the discharge pipe 11 through threads. The smooth surface at the upper end of the extrusion ring 14 extrudes and deforms the annular sealing gasket 13 to ensure a sealed connection between the filter cloth cylinder 15 and the lower end of the discharge pipe 11.

[0054] During air filtration and heating, the fan at the left end of the inner wall of the frame 5 is started. The fan draws in ambient air from the opening on the right side of the frame 5. The air first passes through the filter screen on the outer wall of the connecting plate 10, which intercepts larger particles of impurities. Then, it passes through the inside of the connecting frame 9 and the support screen on the right side and enters the filling box 8. When the air passes through the activated carbon, dust, oil, microorganisms and other impurities are adsorbed, achieving deep purification. The purified air enters the heating tube 3 through the fan outlet. After the honeycomb electric heater 4 is powered on, it heats the air to the temperature required for drying. The heated air enters the drying tower 2 through the opening at the left end of the heating tube 3, providing hot airflow for material drying, thereby preventing impurities in the environment from entering the drying tower 2 and ensuring product quality.

[0055] During material atomization and drying, the liquid material to be dried is pressurized by the booster pump 24 and input through the fixed end of the sealed rotary joint 23, and enters the spray pipe 18 through the rotating end. At the same time, the drive motor is started, driving the shaft 27 to rotate. The gear 26 at the lower end of the shaft 27 meshes with the gear ring 25 on the outer wall of the spray pipe 18, driving the spray pipe 18 to rotate around the central axis of the drying tower 2. The rotating spray pipe 18 atomizes the material into fine droplets through multiple atomizing nozzles 19 on the outer wall. After the droplets diffuse into the interior of the drying tower 2, they come into full contact with the hot air. The hot air quickly removes the moisture from the droplets, forming dried particles. The dried particles settle to the bottom of the drying tower 2 due to gravity, and a small amount of fine powder continues to move downward with the airflow.

[0056] When the spray pipe 18 rotates, the lower synchronous rod drives the connecting rod 20 and the scraper 21 to rotate synchronously. The scraper 21 adheres to the inner wall of the drying tower 2 and continuously scrapes off the dry particles attached to the inner wall of the drying tower 2, thus preventing the material from accumulating on the wall surface.

[0057] Larger dry particles settle directly to the bottom of the drying tower 2 and enter the filter cloth cylinder 15 through the discharge pipe 11. Fine powder carried by the airflow enters the filter cloth cylinder 15 and is intercepted by the fibers of the filter cloth cylinder 15. Meanwhile, the dry exhaust gas is discharged through the pores of the filter cloth cylinder 15, thus achieving solid-gas separation. In this way, it is possible to conveniently separate exhaust gas and fine powder, prevent fine powder from being lost with the exhaust gas, and improve the recovery efficiency.

[0058] When the activated carbon is saturated with adsorption, loosen the bolts between the connecting plate 10 and the frame 5, and pull the connecting plate 10 horizontally to the right, thereby causing the filling box 8 to detach from the inside of the frame 5, so that the activated carbon inside the filling box 8 can be replaced.

[0059] When it is necessary to remove the material inside the filter cloth cylinder 15, rotate the compression ring 14 to remove it, thereby facilitating the removal of the material inside the filter cloth cylinder 15.
