Description

Technical Field

[0001] This utility model relates to the field of granulation technology, specifically to a laboratory-type side-spraying cylinder mechanism. Background Technology

[0002] Side-spraying cylinders are a common mechanism in fluidized bed equipment for pelleting and micro-pellet coating processes. For example, the invention patent with application number 202011619999.X discloses an airbag-sealed side-spraying pelleting structure. In the existing conventional side-spraying cylinder design, gas flows from below the turntable through the gap between the material cylinder and the turntable to reach the top of the turntable to fluidize the material. Relying solely on the gap for air outlet results in defects such as small air volume and limited air outlet area, leading to poor material flowability, easy agglomeration during spraying, and poor fluidization effect. Utility Model Content

[0004] The technical solution adopted by this utility model is as follows: A laboratory-type side-spraying cylinder mechanism includes a material cylinder, a turntable assembly, and a rotary driver. A spray gun is installed inside the material cylinder. The turntable assembly is rotatably disposed inside the material cylinder and is disc-shaped. A first gap exists between the edge of the turntable assembly and the inner wall of the material cylinder. The output end of the rotary driver is connected to the turntable assembly and drives it to rotate.

[0005] The material cylinder has an air inlet located below the first gap. The turntable assembly includes a turntable, and the upper surface of the turntable is provided with a number of evenly distributed and radially extending inclined grooves around its center. The outer ends of the inclined grooves extend to communicate with the first gap.

[0006] Preferably, the upper surface of the turntable is provided with a number of uniformly distributed, radially extending pusher ridges at a position around its center that is different from the inclined groove.

[0007] Preferably, the outer periphery of the turntable has a first conical surface with a diameter that decreases from top to bottom, and a guide ring is provided on the inner periphery of the material cylinder near the outer periphery of the turntable. The inner periphery of the guide ring has a second conical surface that matches the shape of the first conical surface, and a first gap is formed between the second conical surface and the first conical surface.

[0008] Preferably, the inner circumference of the flow guide ring includes a second conical surface and a second cylindrical surface connected sequentially from top to bottom.

[0009] Preferably, the turntable assembly further includes a bearing seat and a main shaft. The bearing seat is fixedly installed inside the material cylinder and is coaxial with the material cylinder. The main shaft is rotatably installed on the bearing seat. The bottom end of the main shaft is connected to the output end of the rotary driver through a coupling to form a rotational linkage. A handwheel is horizontally connected to one side of the material cylinder. The output end of the handwheel passes into the material cylinder and is connected to the main shaft for transmission. The main shaft is driven to rise and fall by rotating the handwheel to adjust the first gap.

[0010] Preferably, it also includes a vent pipe, which has an air inlet and is provided with at least two air ducts evenly distributed around the circumference of the material cylinder. The material cylinder is provided with an air inlet that is the same number as the number of air ducts and corresponds to them one by one. The air outlet of each air duct is connected to the corresponding air inlet.

[0011] Preferably, it also includes a drive chamber installed below the material cylinder, the rotary driver is located inside the drive chamber, the output end of the rotary driver passes through the top of the drive chamber and the bottom of the material cylinder and forms a sealed connection with the two, the air inlet is located at the lower end of the drive chamber, and each air duct is located outside the drive chamber.

[0013] Preferably, the material cylinder is provided with a sight glass.

[0014] Preferably, the material cylinder is connected to a vacuum discharger and a sampler.

[0015] The beneficial effects of this utility model are as follows: By opening a sloping groove structure on the upper end face of the turntable, after the air enters from the air inlet and reaches the upper end of the material cylinder along the first gap, it can also diffuse along the sloping groove toward the center of the material cylinder, increasing the air volume and the air outlet area.

[0026] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0027] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model.

Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0029] like Figures 1 to 8As shown in the figure, a laboratory-type side-spraying cylinder mechanism according to an embodiment of the present invention includes a material cylinder 2, a turntable assembly, and a rotary driver 4. A spray gun 23 is installed inside the material cylinder 2. The turntable assembly is rotatably disposed inside the material cylinder 2 and is disc-shaped. A first gap 21 exists between the edge of the turntable assembly and the inner wall of the material cylinder 2. The output end of the rotary driver 4 is connected to the turntable assembly and drives it to rotate.

[0030] The material cylinder 2 has an air inlet located below the first gap 21. The turntable assembly includes a turntable 31. The upper surface of the turntable 31 is provided with a number of evenly distributed and radially extending inclined grooves 311 around its center. The outer ends of the inclined grooves 311 extend to communicate with the first gap 21.

[0031] With this setup, by opening a sloping groove structure on the upper end face of the turntable, the air inlet reaches the upper end of the material cylinder along the first gap from the air inlet, and can also diffuse towards the center of the material cylinder along the sloping groove, increasing the airflow and the air outlet area. At the same time, the airflow entering the sloping groove can easily blow the material up, reduce material agglomeration, and thus improve the fluidization effect.

[0032] The upper surface of the turntable 31 is provided with a number of uniformly distributed and radially extending pusher ribs 312 at a position around its center that is different from the inclined groove 311.

[0033] This setup allows the pusher protrusions to impact the material, reducing material agglomeration. Simultaneously, the material moves towards the inclined chute to some extent under the action of the pusher protrusions, while the airflow at the inclined chute further lifts the material, thereby increasing the material's fluidity on the turntable and improving the uniformity of the side spraying process.

[0034] The turntable 31 has a first conical surface 313 with a diameter that decreases from top to bottom on its outer periphery. The material cylinder 2 has a flow guide ring 22 located near the outer periphery of the turntable 31 on its inner periphery. The flow guide ring 22 has a second conical surface 221 that matches the shape of the first conical surface on its inner periphery. A first gap 21 is formed between the second conical surface 221 and the first conical surface 313.

[0035] This configuration allows the first and second conical surfaces to work together to further increase the airflow and outlet area, improve the uniformity of air intake, avoid stress concentration, and enhance the material fluidization effect.

[0036] The inner circumference of the flow guide ring 22 includes a second conical surface 221 and a second cylindrical surface 222 connected sequentially from top to bottom.

[0037] With this configuration, the incoming air rises along the second cylindrical surface and then passes through the first gap along the second conical surface, which reduces airflow obstruction.

[0038] The turntable assembly also includes a bearing seat 32 and a main shaft 33. The bearing seat 32 is fixedly installed inside the material cylinder 2 and is coaxial with the material cylinder 2. The main shaft 33 is rotatably installed on the bearing seat 32. The bottom end of the main shaft 33 is connected to the output end of the rotary driver 4 through a coupling 34 to form a rotational linkage. A handwheel 6 is horizontally connected to one side of the material cylinder 2. The output end of the handwheel 6 passes into the material cylinder 2 and is connected to the main shaft 33 for transmission. The main shaft 33 is driven to rise and fall by rotating the handwheel 6 to adjust the first gap 21.

[0039] This setting allows for adjustment of the first gap via the rotation of the handwheel, facilitating fine-tuning of the intake air volume. In this embodiment, a gear coupling is specifically used, which ensures rotational linkage stability while improving the stability of the main shaft relative to the coupling during lifting and lowering without disengaging from the coupling. The transmission connection between the handwheel output end and the main shaft can be specifically a gear and rack configuration, with the gear coaxially mounted at the handwheel output end. A transmission unit is fixedly connected to the outer circumference of the main shaft, and the transmission unit is equipped with a rack that meshes with and is adapted to the gear.

[0040] It also includes a vent pipe 5, which has an air inlet 51 and is provided with at least two air ducts 52 evenly distributed around the circumference of the material cylinder 2. The material cylinder 2 is provided with an air inlet that is the same number as the air ducts 52 and corresponds to them one by one. The air outlet of each air duct 52 is connected to the corresponding air inlet.

[0041] This design further improves ventilation volume and airflow uniformity. In this embodiment, two air ducts are specifically provided, located on opposite sides of the material cylinder. The air inlet of the vent pipe can specifically adopt a 3A quick-connect interface for easy equipment connection and to meet production requirements.

[0042] It also includes a drive chamber 1 installed below the material cylinder 2. The rotary driver 4 is located inside the drive chamber 1. The output end of the rotary driver 4 passes through the top of the drive chamber 1 and the bottom of the material cylinder 2, and forms a sealed connection with the two. The air inlet 51 is located at the lower end of the drive chamber 1, and each air duct 52 is located outside the drive chamber 1.

[0043] With this setup, the rotation of the turntable is powered by a rotary drive at the lower end. The drive chamber is completely isolated from the material cylinder to prevent material contamination. Meanwhile, air ducts are located on both sides of the drive chamber, resulting in a streamlined overall structure.

[0044] An arc-shaped baffle 7 is provided at a position above the material cylinder 2.

[0045] This setting increases the fluidity of materials on the turntable by using an arc-shaped baffle, improves the uniformity of the side spraying process, and can solve the problem of some materials clumping and sticking together during spraying due to poor fluidity.

[0046] The material cylinder 2 is equipped with a sight glass 81.

[0047] This setting allows you to observe the granulation process inside the material cylinder.

[0048] The material cylinder 2 is connected to a vacuum discharger 82 and a sampler 83.

[0049] This setup, equipped with a vacuum discharge function, enables online material discharge and sampling. Additionally, this structure can be equipped with a dedicated material cylinder trolley for easy transportation and organization, reducing labor intensity.

[0050] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
