Description

Technical Field

[0001] This utility model belongs to the field of unloader technology, specifically relating to a bidirectional sealing unloader. Background Technology

[0002] A material conveyor is a commonly used material conveying device widely applied in industrial production. A material conveyor typically consists of a rotor impeller with several blades, a housing, seals, a reducer, and a motor. The rotor impeller is the core component, rotating within a cylindrical housing. Seals ensure the equipment's airtightness, preventing dust leakage or gas backflow. The reducer converts the high-speed motor to a lower speed suitable for the material conveyor's operation while simultaneously increasing torque.

[0003] The motor-driven reducer rotates the impeller inside the cylindrical casing. Material falls from the upper hopper and fills the spaces between the impellers. As the impellers rotate, the material is conveyed to the lower part and discharged. Simultaneously, pressure-equalizing exhaust ports on the side of the machine body can expel the high-pressure gas generated by the impeller's rotation, reducing gas backflow and ensuring the continuity and stability of material conveying.

[0004] Specifically, during the operation of the unloader, its core working component, the impeller, needs to rotate continuously to evenly transport the material from the top hopper to the lower discharge port, completing the unloading action. However, the impeller and housing of traditional unloaders often use a single clearance fit or a simple sealing ring structure at the joint, which can only achieve a basic one-way seal and cannot form a two-way sealing effect. When the unloader is used in a pneumatic conveying system or in a scenario involving pressurized materials, the internal pressurized gas is prone to leak from the gap between the impeller and the housing. On the one hand, this leads to pressure loss within the system, reducing material conveying efficiency; on the other hand, the leaked dusty gas will pollute the surrounding environment, increase equipment cleaning and maintenance costs, and may also affect the health of operators. At the same time, the reverse gas flow can also interfere with the stability of the material falling from the upper hopper. Utility Model Content

[0005] The purpose of this invention is to provide a bidirectional sealing unloader, which addresses the problem that traditional unloaders often use a single clearance fit or a simple sealing ring structure at the impeller-casing connection, which can only achieve a basic unidirectional seal and cannot form a bidirectional sealing effect. When the unloader is used in a pneumatic conveying system or in a scenario involving pressurized materials, the internal pressurized gas is prone to leaking from the gap between the impeller and the casing. This leads to pressure loss within the system, reducing material conveying efficiency; furthermore, the leaked dusty gas pollutes the surrounding environment, increases equipment cleaning and maintenance costs, and may also affect the health of operators. Additionally, the reverse gas flow can interfere with the stability of the material falling from the upper hopper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional sealed unloader, comprising an unloading bin and an infeed shell installed at the top of the unloading bin, a discharge shell connected to the bottom surface of the unloading bin, a reducer connected to one end of the unloading bin, an unloading motor installed on the other side of the reducer, and an impeller installed inside the unloading bin; Positioning rings are adhered to the openings of the mating surfaces of the feed shell and the discharge shell. A positioning spring is connected to the inner wall of the opening of the positioning ring. A linkage plate is connected to the other end of the positioning spring. A sealing ring is connected to the other side of the linkage plate.

[0007] To facilitate adjustment of the sealing ring, in the preferred embodiment of the bidirectional sealing unloader of this utility model, the positioning spring is arranged in a ring inside the positioning ring, and the positioning spring and the linkage plate form an elastic telescopic structure.

[0008] To ensure bidirectional sealing, the sealing ring of the bidirectional sealing unloader of this utility model is preferably made of rubber and extends through and to the outside of the positioning ring.

[0009] To facilitate the distribution and assembly of the vibrators, preferably, the back side of the unloading hopper is connected to a bracket, and the surface of the bracket is connected to a vibrator mounting plate.

[0010] To facilitate precise control of the vibrator, preferably, in this invention's bidirectional sealed unloader, one end of the vibrator mounting plate is connected to the vibrator, and the vibrator is electrically connected to the unloader's power supply.

[0011] To facilitate stable installation of the vibrator, preferably, the surface of the vibrator mounting plate is connected with mounting screws, which are threaded onto the bracket after passing through the vibrator mounting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention involves attaching a positioning ring to the opening at the mating surface of the feed shell and the discharge shell. When the unloader is assembled, the sealing rings at the mating surfaces of the feed shell and the discharge shell contact and press against the assembly surface. At the same time, the linkage plate on the bottom surface of the sealing ring presses against the positioning spring. This causes the sealing ring to deform under pressure, resulting in a sealing structure at both the upper and lower ends of the unloader. This prevents air leakage during unloading and improves the unloading efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 The present invention provides the following technical solution: a two-way sealed unloader, including an unloading bin 1 and a feeding shell 2 installed at the top of the unloading bin 1, a discharge shell 3 connected to the bottom surface of the unloading bin 1, a reducer 4 connected to one end of the unloading bin 1, an unloading motor 5 installed on the other side of the reducer 4, and an impeller 6 installed inside the unloading bin 1. Positioning rings 7 are attached to the openings of the mating surfaces of the feed shell 2 and the discharge shell 3. A positioning spring 8 is connected to the inner wall of the opening of the positioning ring 7. A linkage plate 9 is connected to the other end of the positioning spring 8. A sealing ring 10 is connected to the other side of the linkage plate 9.

[0021] Preferably, the positioning spring 8 is arranged in a ring inside the positioning ring 7, and the positioning spring 8 and the linkage plate 9 form an elastic telescopic structure. In actual use, the elastic telescopic structure of the positioning spring 8 itself facilitates the adjustment of the sealing ring 10 to ensure the sealing connection effect; Preferably, the sealing ring 10 is made of rubber and passes through and extends to the outside of the positioning ring 7. In actual use, the use of the rubber sealing ring 10 facilitates the sealing connection between the upper and lower mating surfaces of the unloader, preventing internal gas leakage.

[0022] Preferably, a support 11 is connected to the back side of the unloading hopper 1, and a vibrator mounting plate 12 is connected to the surface of the support 11.

[0023] Preferably, a vibrator 13 is connected to one end of the vibrator mounting plate 12, and the vibrator 13 is electrically connected to the power supply of the unloader. In actual use, the vibrator 13 facilitates the vibration and removal of materials adhering to the inside of the unloader, preventing long-term adhesion and improving the material discharge efficiency.

[0024] Preferably, a mounting screw 14 is threaded through the surface of the vibrator mounting plate 12, and the mounting screw 14 passes through the vibrator mounting plate 12 and is threadedly connected to the bracket 11. In actual use, by threading the mounting screw 14 through the vibrator mounting plate 12 and connecting it to the bracket 11, the vibrator 13 is ensured to be installed stably.

[0025] The working principle of this utility model is as follows: First, the positioning ring 7 is glued to the opening of the mating surface of the feed shell 2 and the discharge shell 3. When the unloader is assembled, the sealing ring 10 of the mating surface of the feed shell 2 and the discharge shell 3 contacts and presses the assembly surface. At the same time, the linkage plate 9 on the bottom surface of the sealing ring 10 presses the positioning spring 8. At this time, the sealing ring 10 is deformed by compression, so that both the upper and lower ends of the unloader are sealed, thereby avoiding air leakage during unloading and improving the unloading effect. In addition, the vibrator mounting plate 12 on the surface of the vibrator 13 is connected to the bracket 11. The mounting screw 14 passes through the vibrator mounting plate 12 and is threaded to the bracket 11 to ensure that the vibrator 13 is installed stably. At this time, the vibrator 13 is started to vibrate and discharge the material attached to the surface of the impeller 6 inside the unloading bin 1, avoiding the adhesion phenomenon and improving the unloading efficiency.
