Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to an automatic adjustment device for inclined chute air volume. Background Technology

[0002] Inclined chutes are devices that use air to fluidize powdery materials for conveying, and are widely used in industries such as cement, chemicals, and grain. Airflow is a key factor affecting the efficiency and stability of chute conveying. Insufficient airflow leads to slow material conveying speed and easy blockage; excessive airflow increases energy consumption and accelerates equipment wear. Most existing automatic feeding devices use fixed-hole suction pipes, providing low negative pressure. They cannot adjust the pressure according to the needs of different applications, resulting in similar energy consumption across different applications, leading to high energy consumption in low-flow conveying applications. Furthermore, existing chute airflow adjustments mostly rely on manual valve operation, resulting in problems such as untimely adjustments, low accuracy, and high labor intensity. Some semi-automatic control systems have slow response speeds and struggle to adapt to changes in material characteristics and operating conditions, leading to low conveying efficiency and increased operating costs.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses an insert injection mold [CN201120214979.4], which includes an outer tube with an air inlet. An inner tube is installed inside the outer tube. Compressed air flows in from the air inlet and flows out through the installation gap between the outer and inner tubes. The inner tube has multiple air guide grooves arranged in a spiral shape on its surface. The inner tube is installed with an adjusting nut, and turning the nut adjusts the size of the installation gap between the inner and outer tubes. The air guide grooves are inclined at 5 degrees, and multiple inclined air guide grooves are combined to form a spiral shape.

[0004] The above solution has solved the problem of low negative pressure in the suction pipe of the automatic feeding device and the inability to adjust it flexibly to a certain extent. However, the solution still has many shortcomings, such as low air volume adjustment accuracy, slow control response speed, difficulty in adapting to material characteristics and working conditions, resulting in low conveying efficiency and increased operating costs.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1-7 As shown, an automatic chute airflow adjustment device includes a feeding box 1, with feeding chutes 11 connected to both sides of the feeding box 1. The feeding chutes 11 are equipped with a linkage-type material handling adjustment mechanism 3 controlled by a main control module 2. The inner wall of the feeding chutes 11 is equipped with a feeding detection component 4 that communicates with the main control module 2. The end of the feeding chutes 11 near the feeding box 1 is equipped with a discharge control structure 5 connected to the main control module 2. The upper part of the inner side of the feeding box 1 is equipped with a swing-type material guiding structure 6, and the lower part is equipped with a filter material feeding component 7.

[0031] The discharge control structure 5 includes a rotating opening and closing baffle 51 disposed between the feeding box 1 and the feeding chute 11. The rotating opening and closing baffle 51 is rotatably connected by a rotating shaft 52 disposed on the feeding chute 11. A linkage gear 53 is disposed at one end of the rotating shaft 52. A linkage rack 54 is meshed on one side of the linkage gear 53. The linkage rack 54 is connected to the output end of the drive cylinder 55 and is lifted and lowered by the drive cylinder 55 to drive the linkage gear 53 to rotate.

[0032] By controlling the lifting and lowering of the linkage rack 54 through the drive cylinder 55, the linkage gear 53 can be rotated, thereby driving the rotary opening and closing baffle 51 to swing and adjust the opening size, thereby controlling the flow rate of material from the feed box 1 into the feeding chute 11, and forming a linkage with the air volume adjustment.

[0033] As can be seen, the feeding detection component 4 includes a pressure sensor 41, a flow sensor 42, and a material concentration sensor 43 installed in the feeding chute 11. The pressure sensor 41, the flow sensor 42, and the material concentration sensor 43 are arranged at both the inlet and outlet of the feeding chute 11. The pressure sensor 41, the flow sensor 42, and the material concentration sensor 43 are respectively connected to the main control module 2.

[0034] The main control module 2 controls the air supply fan on the air inlet duct to adjust the air volume fed into the feeding chute 11 based on the detection data. For example, when the material concentration is too high, the air volume is increased to improve the conveying efficiency; conversely, the air volume is reduced to avoid energy waste.

[0035] Furthermore, an air inlet pipe is provided on the feeding chute 11, and a blower connected to the main control module 2 is connected to the air inlet pipe.

[0036] Specifically, the inlet of one end of the feeding chute 11 is inserted into the feeding box 1, and the upper end of the feeding box 1 is provided with a feeding funnel 12, and the swing-type guiding structure 6 is provided at the bottom of the feeding funnel 12.

[0037] Furthermore, the oscillating material guiding structure 6 includes an adjusting shaft 61 passing through the feed box 1, and a discharge guide plate 62 located at the bottom of the feed funnel 12 connected to the adjusting shaft 61. The upper end of the feeding chute 11 is provided with a feed through hole 63 corresponding to the discharge guide plate 62.

[0038] The oscillating material guide structure 6 is used to control the material flow direction.

[0039] More specifically, the filter media feeding assembly 7 includes a filter media screen plate 71 disposed in the feeding chute 11. The filter media screen plate 71 is disposed at an inclination in the feeding chute 11, and one end of the filter media screen plate 71 is located on one side of the feeding through hole and the other end is disposed at the discharge port 13 at the bottom of the feeding box 1.

[0040] When the material passes through the feeding chute 11, the filter screen 71 can filter particles or dust, allowing them to fall through the screen into the discharge port 13 for discharge, thus achieving material classification.

[0041] In detail, the linkage material feeding adjustment mechanism 3 includes several rotating adjustment shafts 31 arranged in the feeding chute 11, and the rotating adjustment shafts 31 are provided with swing air plates 32.

[0042] Preferably, there are at least three rotating adjustment shafts 31 arranged coaxially, and each rotating adjustment shaft 31 is provided with a swing air plate 32, and the swing air plates 32 located on different rotating adjustment shafts 31 are arranged in an overlapping manner.

[0043] In addition, the rotating adjustment shaft 31 is driven by the corresponding linkage belt 33 to drive the corresponding swing air plate 32 to rotate, and each swing air plate 32 is provided with a material passage hole 34 of different specifications.

[0044] The rotating adjustment shaft 31 is driven by the linkage belt 33, which drives the swing fan plate 32 to rotate. When the angle of the fan plate changes, the opening and superposition combination of the material passage hole 34 changes accordingly, thereby finely adjusting the air volume and material flow rate. For example, increasing the opening of the material passage hole can increase the air volume, and vice versa, while controlling the amount of material passing through.

[0045] In summary, the principle of this embodiment is as follows: the feeding detection component 4 monitors the air pressure, air volume, and material concentration in the feeding chute 11. The main control module switches and adjusts the angle of the swing fan plate 32 according to the monitoring results, and adjusts the opening degree of the rotary opening and closing baffle 51 through the drive cylinder 55, and controls the air volume of the air intake fan in a coordinated manner. This enables the air volume and feeding amount to be adjusted in a coordinated manner according to the actual working conditions of the feeding chute 11, thereby improving the conveying efficiency and reducing blockage.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
