Description

Technical Field

[0001] The utility model relates to the field of pharmaceutical equipment, in particular to a tail gas dust removal mechanism of a boiling granulation dryer. Background Art

[0002] Fluidized bed granulator is an industrial machine that improves fluidity and reduces dust by granulating powder. Its working principle is: the powder particles of the material are in a ring-shaped fluidized state in the raw material container (fluidized bed), preheated and mixed by the purified heated air, and the adhesive solution is sprayed in atomized form to make several particles aggregate into granules containing adhesive. As the hot air continues to dry the material, the water in the granules evaporates and the adhesive solidifies. This process is repeated continuously to form ideal, uniform, multi-porous spherical particles.

[0003] According to the existing disclosed technology, dust removal is carried out inside the tank body. However, the interior of the tank body is usually designed as a closed structure, which cannot be directly cleaned and maintained. The dust removal mechanism is easily blocked and accumulated by particulate matter and pollutants, resulting in reduced dust removal effect and even unstable equipment operation, thereby increasing production costs and quality risks.

[0004] Therefore, in view of the above problems, an exhaust gas dust removal mechanism of a boiling granulation dryer is proposed. Utility Model Content

[0005] In order to make up for the shortcomings of the prior art, the problem that the internal dust removal and cleaning is difficult and leads to unstable operation of the dust removal structure, the utility model provides an exhaust dust removal mechanism of a boiling granulation dryer.

[0007] Preferably, a liquid inlet pipe is fixedly mounted on the middle portion of the top of the diverter pipe, and an end cover is movably mounted on the top of the dust removal box.

[0008] Preferably, a discharge pipe is fixedly mounted on the bottom of the dust removal box, and a limit plate is threadedly connected to the front of the discharge pipe.

[0009] Preferably, a slot is provided on the front side of the discharge pipe, and a filter box is movably installed inside the slot.

[0010] Preferably, a plurality of filter cloths are movably installed inside the filter box, and a plurality of water seepage holes are opened at the bottom of the filter box.

[0011] Preferably, a conveying pipe is fixedly installed on one side of the dust removal box, and one end of the conveying pipe is threadedly connected to the boiling granulation dryer body.

[0012] Preferably, an exhaust pipe is fixedly mounted on the top of one side of the fluidized bed granulation dryer body, and one end of the exhaust pipe is threadedly connected to the conveying pipe.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model realizes the function of external exhaust gas dust removal through the structural design of the dust removal box, assembly seat, bearing, roller, filter plate, diverter pipe and spray head, and through the mutual cooperation between the structures, thereby capturing large particles of impurities in the exhaust gas and adsorbing small particles of impurities by liquid, thereby improving the dust removal efficiency and better adapting to the capture needs of different types of particulate matter. At the same time, the exhaust gas is dusted outside the tank body, and the open layout makes the dust removal mechanism easy to maintain and clean later, abandoning the dust removal inside the tank body, and solving the problem of unstable operation of the dust removal structure caused by the difficulty of internal dust removal and cleaning.

[0015] 2. The utility model facilitates closing the dust removal box and ensures the sealing of the dust removal box through the arrangement of the end cover, thereby preventing the exhaust gas from escaping or overflowing from the top, and at the same time makes the later maintenance and cleaning work more convenient. The function of solid-liquid separation is achieved through the structural design of the filter cloth and the water seepage hole, and through the mutual cooperation between the structures, so that the solid in the waste liquid can be blocked, thereby realizing the recovery of solid waste and the reuse of liquid resources. Through the arrangement of the exhaust pipe, it is convenient to guide the exhaust gas inside the boiling granulation dryer body out of the device, so as to achieve the purpose of external dust removal.

At the same time, the exhaust gas is dusted outside the tank body, and the open layout makes the dust removal mechanism easy to maintain and clean later, abandoning the dust removal inside the tank body, and solving the problem of unstable operation of the dust removal structure caused by the difficulty of internal dust removal and cleaning.

[0027] A liquid inlet pipe 10 is fixedly installed at the middle part of the top of the shunt pipe 8 , and an end cover 11 is movably installed at the top of the dust removal box 1 .

[0028] Reference Figure 2 and Figure 4 The new type is convenient for introducing liquid into the shunt pipe 8 through the setting of the liquid inlet pipe 10, and then cooperating with the spray head 9 to adsorb small particles of impurities. The setting of the end cover 11 facilitates the closing of the dust removal box 1 to ensure the sealing of the dust removal box 1, thereby preventing the exhaust gas from escaping or overflowing from the top, and at the same time making the subsequent maintenance and cleaning work more convenient.

[0029] A discharge pipe 12 is fixedly mounted on the bottom of the dust removal box 1 , and a limit plate 13 is threadedly connected to the front of the discharge pipe 12 .

[0030] Reference Figure 1 and Figure 2 By setting the discharge pipe 12, it is convenient to discharge the blocked granular impurities in the exhaust gas, and prevent the impurities from staying in the dust removal box 1, thereby ensuring the stable operation of the dust removal mechanism. By setting the limiting plate 13, it is convenient to limit the filter box 15, and avoid shaking of the filter box 15 when working, thereby ensuring the stability of solid-liquid separation.

[0031] A slot 14 is provided on the front side of the discharge pipe 12 , and a filter box 15 is movably installed inside the slot 14 .

[0032] Reference Figure 1 , Figure 2 , Figure 5 The card slot 14 is provided to facilitate temporary carrying of the filter box 15 , and the filter box 15 is provided to facilitate secondary filtration of waste materials inside the discharge pipe 12 .

[0033] A plurality of filter cloths 16 are movably installed inside the filter box 15 , and a plurality of water seepage holes 17 are provided at the bottom of the filter box 15 .

[0034] Reference Figure 5Through the structural design of the filter cloth 16 and the water seepage holes 17, and through the mutual cooperation between the structures, the function of solid-liquid separation is achieved, thereby blocking the solids in the waste liquid, thereby realizing the recovery of solid waste and the reuse of liquid resources.

[0035] A conveying pipe 18 is fixedly installed on one side of the dust removal box 1, and one end of the conveying pipe 18 is threadedly connected to a boiling granulation dryer body 19.

[0036] Reference Figure 1 and Figure 2 By setting the delivery pipe 18, it is convenient to provide guidance for the exhaust gas, ensuring that the exhaust gas can completely enter the dust removal box 1.

[0038] Reference Figure 1 By setting the exhaust pipe 20, it is convenient to guide the exhaust gas inside the boiling granulation dryer body 19 out of the device, thereby achieving the purpose of external dust removal.

[0039] Working principle: When using this device, the dust removal box 1 is closed through the end cover 11, and the exhaust gas in the boiling granulation dryer body 19 reaches the inside of the dust removal box 1 through the exhaust pipe 20 and the conveying pipe 18. At the same time, the liquid is introduced through the liquid inlet pipe 10, and the liquid reaches the spray head 9 through the diversion pipe 8. The liquid is released through the spray head 9, and the liquid pushes the filter plate 6, and the roller 4 is driven to rotate through the filter plate 6. The energy attenuation of the roller 4 during rotation is reduced through the bearing 3. The large particle impurities in the exhaust gas are captured by the filter plate 6. After the exhaust gas passes through the filter plate 6, The liquid released by the spray head 9 adsorbs small particle impurities in the exhaust gas. At the same time, the liquid of the spray head 9 can clean the surface of the filter plate 6. The captured and adsorbed granular impurities fall with the liquid and are released from the dust removal box 1 through the discharge pipe 12. During this period, the waste liquid enters the filter box 15 and is blocked by the filter cloth 16 for blocking solid particles. After the waste liquid penetrates the filter cloth 16, it is released from the discharge pipe 12 through the seepage hole 17. During later maintenance and cleaning, it is only necessary to open the end cover 11 to complete the replacement of the filter plate 6 and the cleaning of the inside of the dust removal box 1.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
