Description

Technical Field

[0001] This utility model relates to drying technology, specifically a dryer with dust removal function. Background Technology

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials, used for drying objects. The dryer heats the material to vaporize the moisture (generally water or other volatile liquid components), and then uses negative pressure suction or air blowing to rapidly remove the moisture, thus obtaining solid materials with a specified moisture content.

[0003] In actual use, dust from the raw materials enters the pipeline with the airflow in existing dryers. This dust not only accumulates on the inner wall of the pipeline, leading to a decrease in airflow and even pipeline blockage, but also wears down and deposits on the fan blades, causing accelerated blade wear, changes in blade shape, and a decrease in fan performance and efficiency. Therefore, dryers are equipped with dust removal structures, usually bag filters. However, with prolonged use or high dust content, dust adheres to the outer wall of the filter bags, causing blockage of the filter pores, a decrease in airflow, and a reduction in dust removal efficiency. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a dryer with dust removal function, which adds a vibration unit. By striking the frame, the frame vibrates to shake off the dust adhering to the outer wall of the filter bag.

[0005] To achieve the above technical objectives, this utility model adopts the following technical solution: a dryer with dust removal function, comprising a drying tank and a dust removal component. The drying tank is used to dry materials, and the dust removal component is connected to the drying tank and used to filter dust. The dust removal component includes a cylinder, with a top cover on the top of the cylinder. An installation ring and a pressure ring are provided inside the cylinder, with the pressure ring located above the installation ring. The pressure ring and the installation ring cooperate to press down the edge of the cloth bag. A frame is provided below the pressure ring, and the frame is used to support the inner wall of the cloth bag. A motor is provided on the top cover, and a vibrating disc is provided inside the frame. The motor drives the vibrating disc to rotate. Several vibration units are provided on the outer periphery of the vibrating disc, and the vibration units collide with the frame to generate vibration.

[0006] Preferably, the frame is composed of several support rods, the top ends of which are fixed to the inner wall of the pressure ring.

[0007] Preferably, the vibration unit includes a rotating shaft and a lever plate. The rotating shaft is rotatably connected to the outer periphery of the vibrating disk. One end of the lever plate is fixed to the rotating shaft, and a spring is provided between the other end of the lever plate and the vibrating disk.

[0008] Preferably, the bottom end of the cylinder is provided with a discharge port, one side of the bottom of the cylinder is provided with an air inlet, the air inlet is connected to the drying tank, the top of the cylinder is provided with an exhaust port, and the mounting ring and pressure plate are located between the air inlet and the exhaust port.

[0009] Preferably, the top of the cylinder is provided with a backflush port.

[0010] In summary, this utility model achieves the following technical effects:

[0011] This utility model of a dryer with dust removal function uses a motor to drive a vibrating plate to rotate, causing a plate to strike each support rod of the frame in sequence. This causes the support rod to vibrate and shake off the dust adhering to the outer wall of the filter bag near the support rod, clearing the filter bag pores blocked by dust, ensuring airflow, and improving filtration efficiency.

[0022] Example 1:

[0023] like Figure 1-2As shown, a dryer with dust removal function includes a drying tank 14 and a dust removal assembly. The drying tank 14 is used to dry materials, and the dust removal assembly is connected to the drying tank 14 and used to filter dust. The dust removal assembly includes a cylinder 1, with a top cover 2 covering the top of the cylinder 1. An installation ring 7 and a pressure ring 8 are provided inside the cylinder 1. The pressure ring 8 is located above the installation ring 7, and the pressure ring 8 and the installation ring 7 cooperate to press down the edge of the cloth bag. A frame is provided below the pressure ring 8, and the frame is used to support the inner wall of the cloth bag. A motor 11 is provided on the top cover 2, and a vibrating plate 10 is provided inside the frame. The motor 11 drives the vibrating plate 10 to rotate. Several vibration units are provided on the outer periphery of the vibrating plate 10, and the vibration units vibrate by colliding with the frame.

[0024] The pressure ring 8 is fixed to the mounting ring 7 by bolts.

[0025] The dryer with dust removal function in this embodiment uses a motor 11 to drive the vibratory plate 10 to rotate, so that the paddle plate 13 knocks on each support rod 12 of the frame in sequence, causing the support rod 12 to vibrate and shake off the dust attached to the outer wall of the filter bag 9 near the support rod 12, clearing the filter holes of the filter bag 9 blocked by dust, ensuring airflow and improving filtration efficiency.

[0026] The drying tank 14 is equipped with a stirrer, which is driven by a stirring motor to rotate and dry the material inside the drying tank 14. The drying tank 14 is equipped with a feed inlet and a discharge outlet. The material enters from the feed inlet and exits from the discharge outlet. The drying tank 14 is equipped with an air inlet pipe, which is connected to an air intake fan through a heater. The air intake fan blows in airflow, which is heated by the heater and then enters the drying tank 14. Together with the stirrer, the material is stirred so that it is heated evenly and dried. The dust-containing waste airflow enters the cylinder 1 for dust removal treatment.

[0027] The frame is composed of several support rods 12, the top of which is fixed to the inner wall of the pressure ring 8.

[0028] like Figure 3 As shown, the vibration unit includes a rotating shaft and a deflector plate 13. The rotating shaft is rotatably connected to the outer periphery of the vibrating plate 10. One end of the deflector plate 13 is fixed to the rotating shaft, and a spring is provided between the other end of the deflector plate 13 and the vibrating plate 10. When the airflow enters the cylinder 1, the filter bag 9 will be blown by the airflow and stick to the support rod 12. Therefore, when the deflector plate 13 hits the support rod 12, the vibration of the support rod 12 will cause the filter bag 9 to shake, causing the dust to fall off. Although some dust re-diffuses, some dust falls to the discharge port 3 and clears the filter holes of the filter bag 9 that are blocked by dust.

[0029] The bottom end of the cylinder 1 is provided with a discharge port 3, and the bottom side of the cylinder 1 is provided with an air inlet 4. The air inlet 4 is connected to the drying tank 14. The top of the cylinder 1 is provided with an exhaust port 5. The mounting ring 7 and the pressure plate are located between the air inlet 4 and the exhaust port 5. The exhaust port 5 is provided with an exhaust fan, which is used to guide the airflow out of the cylinder 1.

[0030] The top of the cylinder 1 is provided with a backflush port 6; the backflush port 6 is connected to a compressed air tank through a solenoid valve. The solenoid valve is opened periodically to backflush and expand the filter bag 9 to remove dust, and blow the dust on the outer wall of the filter bag 9 to the bottom of the cylinder 1.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
