Description

Technical Field

[0001] This utility model relates to the field of light blowing for impurity removal, specifically to a mobile variable diameter speed-adjustable impurity cleaning blower. Background Technology

[0002] During the storage process, rice contains a large amount of husk, which usually needs to be removed by cleaning equipment. Grain is transported in the warehouse by conveyor belts connected to the conveyor frame and transmission. Existing cleaning equipment includes large-scale equipment such as cyclones, combined cleaning screens, and environmentally friendly vibrating screens. Although these can effectively remove husks from rice impurities, they are bulky and require a separate conveyor to be installed between the conveyor frame and the cleaning equipment, resulting in high installation and maintenance costs. Utility Model Content

[0003] The present invention aims to provide a mobile variable diameter speed-adjustable impurity cleaning blower to solve the problems of large size and high cost of existing rice cleaning equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a mobile variable diameter speed-regulating impurity cleaning blower, including a mounting frame detachably connected to the top of the conveyor frame, a blower mounted on the top of the mounting frame, an air separation chamber formed between the mounting frame and the conveyor belt, a variable diameter air separation port opened between the blower and the air separation chamber, the air separation port having a specific shape and being consistent with the conveying direction of the conveyor belt.

[0005] The beneficial effects of this solution are as follows: the equipment is small in size, and its position on the conveyor can be changed by mounting the frame, which not only improves the flexibility of the equipment but also reduces the transportation and installation costs of the equipment. In addition, the existing cleaning equipment cannot adjust the cleaning angle during use, which causes some of the rice to be blown to the ground and mixed with the husks, making it difficult to return to the storage. However, the variable diameter setting of the air separator in this solution can adjust the cleaning angle by changing the diameter, so that it can be adjusted according to the actual situation of the grains on the conveyor belt, so that the grains are not blown out and the efficiency of grain cleaning is improved.

[0006] Preferably, as an improvement, mounting rods are symmetrically slidably arranged on both sides of the bottom of the mounting frame in the conveyor belt conveying direction, and the sliding direction of the mounting rods is perpendicular to the conveyor belt conveying direction.

[0007] The beneficial effects are as follows: different conveyor frames and conveyor belts have different widths. When the mounting frame is installed on conveyor frames of different widths, the distance between the mounting rods on both sides can be adjusted by sliding the symmetrically arranged mounting rods on both sides, so that the mounting frame can adapt to several different widths of conveyor frames.

[0008] Preferably, as an improvement, the mounting bracket has an air inlet at the bottom of the fan, and an air collecting hood is fixed at the air inlet on the mounting bracket. A rectangular air outlet is opened at the bottom of the air collecting hood, and the long side of the air outlet is arranged in the same direction as the conveyor belt.

[0009] Preferably, as an improvement, the air collecting hood is symmetrically and rotatably provided with baffles on both sides of the long side of the air outlet, and an adjusting component is provided between the baffles and the air collecting hood. The air separator is formed between the two baffles, and the adjusting component is used to adjust the size of the air separator.

[0010] Preferably, as an improvement, air guides are symmetrically arranged on both sides of the mounting frame, and the air guides are used to discharge impurities.

[0011] The beneficial effects are as follows: the air of the cleaning equipment in the existing technology does not have directional control, and the air blows out rice husks in a disorderly manner, resulting in a lot of dust at the work site. However, the air guide hood used in this solution can orderly blow out and collect impurities from a specific direction.

[0012] Preferably, as an improvement, the mounting frame has grooves on both sides perpendicular to the conveyor belt and in the opposite direction of the conveyor belt, allowing the mounting rod to slide.

[0013] Preferably, as an improvement, the fan is configured as an explosion-proof axial flow fan.

[0014] The beneficial effects are as follows: The explosion-proof axial flow fan adopts a blade design with wide blades and a large chord length, forward tilt and spatial twist, which can achieve the air volume and air pressure of traditional high-speed drive even when driven at low speed, while significantly reducing aerodynamic noise.

[0015] Preferably, as an improvement, a control system is also installed at the top of the mounting bracket. The control system is electrically connected to the fan and is used to control the fan speed. Attached Figure Description

[0020] The following detailed description illustrates the specific implementation method:

[0021] The reference numerals in the accompanying drawings include: mounting bracket 1, air separator 11, mounting plate 12, slide rail 121, mounting rod 122, galvanized steel plate 123, air inlet 13, air collector hood 14, air outlet 141, baffle plate 142, screw 143, air separator port 144, air guide hood 15, explosion-proof axial flow fan 2, and control system 3.

[0022] Example

[0023] The basic implementation examples are as follows: Figures 1-4 As shown, Figures 1-3 The movable variable diameter speed-regulating impurity cleaning blower shown includes a mounting frame 1. The mounting frame 1 includes a mounting plate 12 at the top and galvanized steel plates 123 fixedly welded to the front and rear ends of the mounting plate 12. The galvanized steel plates 123 at the front and rear ends are arranged in the same direction as the conveyor belt. Air guide hoods 15 are symmetrically fixedly welded to the left and right sides of the mounting plate 12 on the conveyor belt. An air separation chamber 11 is formed between the mounting plate 12, the galvanized steel plates 123 at the front and rear ends, the air guide hoods 15 on the left and right sides, and the conveyor belt.

[0024] Mounting plate 12 has symmetrical grooves 121 on both sides of the conveyor belt, perpendicular to the conveying direction of the conveyor belt. The grooves 121 penetrate the mounting plate 12. Mounting rod 122 is slidably connected to the mounting plate 12 at the grooves 121. A plate is fixedly welded to the top of the mounting rod 122. The plate has mounting holes corresponding to the grooves 121. Mounting screws are threadedly connected to the plate of the mounting rod 122 and the mounting holes. The mounting screws pass through the grooves 121 and are connected to the mounting rod 122 through the mounting holes. When the mounting rod 122 needs to slide on the mounting plate 12, the mounting screws are loosened and the position is adjusted by sliding the screw 143 in the grooves 121. Finally, the mounting screws are tightened so that the nuts of the mounting screws are tightly abutted against the mounting plate 12, thereby fixing the mounting rod 122 to the mounting plate 12. The bottom end of the mounting rod 122 is detachably connected to the conveyor frame by bolts.

[0025] like Figures 3-4As shown, the mounting plate 12 has an air inlet 13. An air collecting hood 14 is fixedly welded to the bottom of the mounting plate 12 within the air separation chamber 11. The bottom of the air collecting hood 14 has a rectangular air outlet 141. The top opening of the air collecting hood 14 has the same shape and size as the air inlet 13. The long side of the air outlet 141 is in the same direction as the conveyor belt's conveying direction. The plate between the air outlet 141 and the top opening of the air collecting hood 14 is smoothly inclined. The long side of the bottom air outlet 141 of the air collecting hood 14 is hinged by an adjusting member. A wind deflector 142 is attached. A hinge structure is provided between the wind collector hood 14 and the wind deflector 142. The hinge structure includes a hinge plate that is rotatably connected and welded to the wind collector hood 14 and the wind deflector 142 respectively. A threaded seat is fixedly welded to the wind collector hood 14. The adjusting component is a screw 143 that is threadedly connected to the threaded seat. A ball joint is provided between the screw 143 and the wind deflector 142. A ball socket is fixedly welded to the wind deflector 142. A ball head is fixedly welded to the end of the screw 143 near the wind deflector 142. The ball head is embedded in the ball socket.

[0026] like Figure 1 As shown, an explosion-proof axial flow fan 2 is fixedly installed on the top of the air inlet 13 on the mounting plate 12. The explosion-proof axial flow fan 2 is used to blow air into the air inlet 13. A control system 3 is also fixedly installed on the top of the mounting plate 12. The control system 3 includes a speed-regulating frequency converter and a speed-regulating circuit. The speed of the explosion-proof axial flow fan 2 is adjusted by the speed-regulating frequency converter to adapt to the needs of removing impurities from various grains. By adjusting to a suitable wind speed, not only can impurities be blown out, but the grain can also be kept on the conveyor belt.

[0027] Its working principle is as follows: the grain on the conveyor belt is piled up in a triangular shape and transported with the conveyor belt. When the grain does not enter the air separation chamber 11, the grain on the conveyor belt is observed to see the arrangement characteristics of its husk. Then, the distance between the two side baffles 142 is adjusted by rotating the screw 143, thereby controlling the width of the air separation port 144 according to the situation. The explosion-proof axial flow fan 2 blows the air into the air separation chamber 11 and blows it out with the air guide shrouds 15 on both sides. The impurities in the grain are also blown out from the air guide shrouds 15. According to the different types of grain and the different arrangement of husks, the speed of the explosion-proof axial flow fan 2 is adjusted by the control system 3.
