[0002] A fluidized bed granulator is a device mainly used for pharmaceutical granulation and coating. It uses fluidized bed technology to fluidize powder or granular materials in heated air while simultaneously spraying in a binder to form granules.

[0003] Fluidized bed granulators used in chemical and pharmaceutical engineering generate a large amount of material dust during operation. This dust is usually absorbed by filter bags. However, when a large amount of dust accumulates on the surface of the filter bags, it will seriously affect production efficiency. The common way to clean the filter bags is to use an electric cylinder to shake the filter bags up and down. However, this method is costly and does not provide sufficient and rapid cleaning of the filter bag surface.

[0004] Now, a fluidized bed granulator with a pulse dust removal mechanism for chemical and pharmaceutical engineering is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fluidized bed granulator for chemical and pharmaceutical engineering with a pulse dust removal mechanism, so as to solve the problem mentioned in the background art of not being able to clean the surface of the filter bag sufficiently and quickly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fluidized bed granulator for chemical and pharmaceutical engineering with a pulse dust removal mechanism, comprising a material tank, a spray canister installed at the top of the material tank, a filter canister installed at the top of the spray canister, an air jet canister installed at the bottom of the material tank, a heater fixedly connected to one side of the air jet canister, a blower installed on one side of the heater, a feed inlet on one side of the material tank, a first observation window at the front end of the material tank, a control base installed at the front end of the spray canister, multiple sets of filter bags installed inside the filter canister, an exhaust port at the top of one side of the filter canister, and an automatic pulse dust removal mechanism installed inside the filter canister;

[0007] The automatic pulse dust removal mechanism includes a spray pipe installed inside the filter tank. A solenoid valve is installed on one side of the spray pipe, and an air storage tank is fixedly connected to one side of the filter tank. A pulse valve is installed between the air storage tank and the spray pipe. Multiple sets of first nozzles are opened at the bottom of the spray pipe, an air outlet is opened on one side of the spray pipe, and a second observation window is opened at the front end of the filter tank.

[0008] As a further technical solution of this utility model, the control seat is electrically connected to the solenoid valve, and multiple sets of the first nozzles are symmetrically distributed, with each first nozzle corresponding to a filter bag.

[0009] As a further technical solution of this utility model, the feature is that: the material container, the spray container, and the filter container are internally connected, and the inlet is internally connected to the material container.

[0010] As a further technical solution of this utility model, the blower is electrically connected to the control base, and the jet canister, heater and material tank are internally connected.

[0011] As a further technical solution of this utility model, a fixed base is fixedly connected inside the spray can, a spray disc is provided below the fixed base, an electric cylinder is installed between one side of the bottom end of the fixed base and the spray disc, a spray hose is movably connected between one side of the bottom end of the fixed base and the spray disc, and multiple sets of second nozzles are provided at the bottom end of the spray disc.

[0012] As a further technical solution of this utility model, multiple sets of second nozzles are symmetrically distributed, and the spray disc can move up and down under the action of an electric cylinder.

[0013] As a further technical solution of this utility model, a servo motor is installed inside the jet can, a movable shaft is movably connected inside the material container, two sets of stirring blades are installed at the top of the outer side of the movable shaft, two sets of scrapers are installed at the bottom of the outer side of the movable shaft, and a cleaning brush is installed on the side of the two sets of scrapers away from the movable shaft.

[0014] As a further technical solution of this utility model, the output end of the servo motor is connected to the movable shaft, the servo motor is electrically connected to the control base, and the cleaning brush is tightly fitted to the inside of the material tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the fluidized bed granulator for chemical and pharmaceutical engineering with pulse dust removal mechanism not only removes dust from the surface of the filter bag, but also achieves a more uniform contact distribution between the material and the liquid, and also cleans the adhering substances on the inner wall of the container.

[0016] (1) By setting up an air storage tank, pulse valve, solenoid valve, nozzle, first nozzle, air outlet and second observation window, when in use, the material is put into the storage tank through the feed port, and the blower is started through the control seat. The air enters the storage tank through the heater and the air jet canister. The dust generated by the material is blocked by the filter bag when passing through the filter tank, which prevents the material from being discharged to the outside environment through the exhaust port. After a long period of processing, a lot of dust will accumulate on the surface of the filter bag. The staff can observe the condition of the filter bag through the second observation window. The solenoid valve and pulse valve are started through the control seat to put the gas in the air storage tank along the nozzle. Multiple sets of nozzles are opened at the bottom of the nozzle. The nozzles correspond one-to-one with the positions of the filter bags below, thereby removing the dust on the surface of the filter bags and improving production efficiency.

[0017] (2) By setting up a fixed base, spray hose, electric cylinder, spray plate and second nozzle, when in use, a fixed base is installed inside the spray tank, a spray plate is set below the fixed base, and a spray hose is movably connected between the spray plate and the fixed base. The operator uses a specific liquid to enter the spray plate through the spray hose. The height of the spray plate inside the spray tank can be adjusted by the electric cylinder. The second nozzle is symmetrically distributed, so as to achieve a more uniform contact distribution between the material and the liquid below.

[0018] (3) By setting up a servo motor, a movable shaft, stirring blades, scrapers and cleaning brushes, when in use, a servo motor is installed at the top inside the spray tank, the movable shaft is connected to the inside of the material tank, and two sets of stirring blades are installed at the top outside the movable shaft. By starting the servo motor to drive the stirring blades, the material distribution is more uniform. Since the spray may produce sticky substances when it hits the inner wall of the material tank, two sets of scrapers are installed at the bottom outside the movable seat, and cleaning brushes are installed on the outside of the scrapers. The cleaning brushes are in close contact with the inner wall of the material tank, thereby cleaning the sticky substances. Attached Figure Description

The multiple sets of second nozzles 23 are symmetrically distributed. The spray disc 22 can move up and down under the action of the electric cylinder 21.

[0031] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, during use, a fixed base 19 is installed inside the spray can 2, and a spray disc 22 is set below the fixed base 19. A spray hose 20 is movably connected between the spray disc 22 and the fixed base 19. The operator uses a specific liquid to enter the spray disc 22 through the spray hose 20. The height of the spray disc 22 inside the spray can 2 can be adjusted by the electric cylinder 21. The second nozzles 23 are symmetrically distributed, so as to achieve a more uniform contact distribution between the material and the liquid below.

[0032] A servo motor 24 is installed inside the jet tank 4. A movable shaft 25 is movably connected inside the material tank 1. Two sets of stirring blades 26 are installed at the top of the outer side of the movable shaft 25. Two sets of scrapers 27 are installed at the bottom of the outer side of the movable shaft 25.

The servo motor 24 is electrically connected to the control base 9. The cleaning brush 28 is in close contact with the inside of the material tank 1.

[0033] Specifically, such as Figure 1 and Figure 5 As shown, during use, a servo motor 24 is installed at the top inside the spray can 4, and a movable shaft 25 is movably connected inside the material tank 1. Two sets of stirring blades 26 are installed at the top outside the movable shaft 25. By starting the servo motor 24, the stirring blades 26 are driven, thereby achieving a more uniform material distribution. Since adhesive substances may appear when the spray hits the inner wall of the material tank 1, two sets of scrapers 27 are installed at the bottom outside the movable seat. A cleaning brush 28 is installed on the outside of the scraper 27. The cleaning brush 28 is in close contact with the inner wall of the material tank 1, thereby achieving the cleaning of the adhesive substances.

[0034] Working Principle: In use, the material is first fed into the holding tank 1 through the feed inlet 7, and the blower 6 is started through the control seat 9. The air enters the holding tank 1 through the heater 5 and the air jet canister 4. The dust generated by the material is blocked by the filter bag 10 when it passes through the filter tank 3, preventing the material from being discharged into the external environment through the exhaust port 11. Over a long period of processing, a large amount of dust will accumulate on the surface of the filter bag 10. The operator can observe the condition of the filter bag 10 through the second observation window 18. The solenoid valve 14 and the pulse valve 13 are started through the control seat 9 to release the gas in the air storage tank 12 along the spray pipe 15. Multiple sets of nozzles are opened at the bottom of the spray pipe 15, and the nozzles correspond one-to-one with the positions of the filter bags 10 below, thereby removing the dust on the surface of the filter bags 10 and improving production efficiency. Secondly, a fixed seat 19 is installed inside the spray tank 2, and a spray disc is set below the fixed seat 19. 22. A spray hose 20 is movably connected between the spray disc 22 and the fixed base 19. The operator uses a specific liquid to enter the spray disc 22 through the spray hose 20. The height of the spray disc 22 inside the spray tank 2 can be adjusted by the electric cylinder 21. The second nozzles 23 are symmetrically distributed, so as to achieve a more uniform contact distribution between the material and the liquid below. At the same time, by installing a servo motor 24 at the top of the inside of the spray tank 4, and movably connecting the inside of the material tank 1 to the movable shaft 25, two sets of stirring blades 26 are installed at the top of the outer side of the movable shaft 25. By starting the servo motor 24 to drive the stirring blades 26, the material distribution is more uniform. Since there may be sticky substances when the spray hits the inner wall of the material tank 1, two sets of scrapers 27 are installed at the bottom of the outer side of the movable base. A cleaning brush 28 is installed on the outer side of the scraper 27. The cleaning brush 28 is in close contact with the inner wall of the material tank 1, so as to clean the sticky substances.
