Description

Technical Field

[0001] This invention relates to a high-efficiency pellet dust removal device. Background Technology

[0002] In the polyolefin industry (PP, PE, EVA, etc.) or the new materials industry (ABS, PC, POM, PS, lithium battery materials, etc.), finished particles generate fine powder, stringy material, and metallic impurities during transportation due to extrusion from pelletizing and rotating equipment, as well as wear and tear on conveying pipes and bends. This significantly impacts the bag breakage rate during subsequent packaging. Furthermore, the presence of these fine powders, stringy materials, and metallic impurities severely affects product quality, especially for lithium battery materials and optical-grade materials, making it a critical step in quality improvement. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of dust and impurities in existing finished product particles affecting product quality.

The inlet is located at the top of the shell and is provided with an inlet guide. A distributor is provided inside the inlet guide. A stepped guide device is provided at the bottom of the shell corresponding to the distributor. An air blowing port is provided on the step and a blowing device is provided corresponding to the air blowing port. A gas guiding channel is provided above the air blowing port. A tail gas suction pipe is provided at the top of the shell. The air inlet of the tail gas suction pipe is connected to the air outlet of the gas guiding channel. The outlet is located at the bottom of the shell below the guide device.

[0021] The structure of the present invention will be further described below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 5 A high-efficiency granular powder removal device includes a shell 1, with an inlet 11 and an outlet 12 on the shell 1. The inlet is located at the top of the shell and is equipped with an inlet guide 14. A distributor 2 is located inside the inlet guide 14. A stepped guide device 3 is located at the bottom of the shell below the distributor. An air blowing port 31 is located on the step and a blowing device 4 is located corresponding to the air blowing port. A gas guiding channel 13 is located above the air blowing port. A tail gas suction pipe 5 is located at the top of the shell. The air inlet of the tail gas suction pipe is connected to the air outlet of the gas guiding channel. The outlet is located at the bottom of the shell below the guide device. The shell is cylindrical, with the feed guide located at the center of the shell. The feed guide has a bent structure, and the gas guide channel is located on the side of the feed guide. In use, the granules are poured in from the feed guide at the top of the shell. The granules are distributed by the distributor onto the stepped guide device. Air blowing ports are provided on the steps. As the granules jump down on the stepped guide device, the air blowing ports blow the dust in the granules into the gas guide channel. The exhaust pipe sucks away the exhaust gas and dust, thereby removing dust from the granules and improving the product quality of the granules. In addition, this device has a simple structure, high dust removal efficiency, and low cost.

[0023] In this embodiment, the exhaust gas suction pipe 5 is inverted L-shaped, and an arc-shaped buffer chamber 51 is provided at the inverted L-shaped corner of the exhaust gas suction pipe. The buffer chamber is used to buffer and store the gas, thereby reducing the gas velocity and enabling the exhaust gas to be discharged stably. At the same time, the buffer chamber allows the decelerated granules to fall into the guiding device under the action of gravity.

[0024] In this embodiment, an observation mirror 7 is provided on the side wall of the gas guide channel. The observation mirror is used to observe the amount of granules in the gas guide channel, thereby adjusting the air pressure of the blowing device to prevent the granules from being blown into the tail gas suction pipe.

[0025] In this embodiment, a sensor 8 for sensing the amount of granules is provided in the gas flow channel. The sensor 8 can be a photoelectric sensor. It is used to sense the amount of granules in the gas flow channel, thereby adjusting the air pressure of the blowing device to prevent granules from being blown into the tail gas suction pipe.

[0026] In this embodiment, the distributor 2 includes a conical first distributor 21 movably disposed within the feed guide and a conical second distributor 22 disposed at the top of the stepped section of the guide device. A positioning sleeve 23 is provided on the feed guide. The first distributor is slidably connected to the positioning sleeve via a sliding rod 24. The side wall of the positioning sleeve has an internal thread, and a screw 25 is disposed within the internal threaded hole. An adjustment knob 26 is provided at one end of the screw. When the height of the first distributor needs to be adjusted, the adjustment knob is rotated to separate the screw from the sliding rod, allowing the height of the distributor to be adjusted vertically. After adjustment, the adjustment knob is rotated again to engage the screw with the sliding rod, fixing the sliding rod in place. This allows for adjustment of the height of the first distributor within the feed guide as needed, ensuring the granules fall evenly onto the second distributor, and also adjusting the granule falling speed. The granules are distributed by the first distributor and then by the second distributor, ensuring they fall evenly onto the guide device.

[0027] In this embodiment, the flow guiding device 3 includes an inverted V-shaped support frame 31 with an inverted V-shaped cross-section and a first step 32 evenly arranged on the inverted V-shaped support frame. The distributor is positioned at the center of the inverted V-shaped support frame. After being distributed by the distributor, the granules fall onto the first step and bounce down, thus evenly dispersing the granules. The inverted V-shaped support frame is fixedly connected to the shell through a support frame fixing frame 311.

[0028] In this embodiment, the blowing device 4 includes a first air duct 41 evenly arranged at the bottom of the inverted V-shaped support frame and a first ventilation pipe 42 located below the first air duct. Each first air duct has a first ventilation pipe outlet 421, which is a Venturi tube structure. Gas is introduced into the first ventilation pipe and ejected through the first ventilation pipe outlet, thereby blowing away dust from the granules. The Venturi tube enables the ejected gas to have a certain velocity and pressure, improving the dust separation efficiency.

[0029] In this embodiment, the flow guiding device 3 further includes a V-shaped support frame 33 with a V-shaped cross-section disposed below the corresponding inverted V-shaped support frame, and a second step 34 evenly arranged on the V-shaped support frame. The discharge port is located in the middle of the V-shaped support frame. The upper and lower ends of the inverted V-shaped support frame are fixedly connected to the bottom of the shell. The granules bounce down from the first step to the second step and then bounce down to the discharge port for discharge. This further disperses the granules evenly.

[0030] In this embodiment, the blowing device 4 further includes a second air duct 43 evenly arranged on both sides of the corresponding V-shaped support frame and a second ventilation pipe 44 located on the side of the second air duct. The second ventilation pipe is connected to the second ventilation pipe inlet 441 on the housing. Each second air duct has a second ventilation pipe outlet, which is a Venturi tube structure. Gas is introduced into the second ventilation pipe and ejected through the second ventilation pipe outlet, thereby blowing away the dust in the granules. The Venturi tube enables the ejected gas to have a certain velocity and pressure, improving the dust separation efficiency.

[0031] In this embodiment, a discharge pipe 8 is provided inside the discharge port 12, and a magnetic adsorption device 6 is provided on the side of the discharge pipe for adsorbing and collecting metal particles in the granules. The magnetic adsorption device adsorbs and collects the metal particles in the granules at the discharge port.

[0032] Although specific embodiments of the present invention have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of the present invention. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of the present invention.
