Description

Technical Field

[0001] The present invention relates to the technical field of feeding stations, and particularly relates to a negative-pressure dust-free ton bag feeding station and its working method. Background Art

[0002] During the feeding process of ton bag packaged powder materials, an electric hoist is usually used to lift the large bag to the unpacking station, and the operator unties the discharge port at the bottom of the large bag to convey the powder materials to a silo or other equipment.

[0003] In the existing device during the feeding process, powder is likely to spill out from the feed hopper. At this time, the staff inhales the floating powder into the body, which directly affects physical health; the structure of the existing device is not perfect enough to achieve the combination of the stability of the frame body, the adaptability of the frame body to the placement position, and the stability during the transfer of the frame body.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a negative-pressure dust-free ton bag feeding station and its working method are provided, with the expectation of achieving a more practical value purpose. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a negative-pressure dust-free ton bag feeding station and its working method to solve the problems that in the existing device during the feeding process, powder is likely to spill out from the feed hopper, and at this time, the staff inhales the floating powder into the body, directly affecting physical health; the structure of the existing device is not perfect enough to achieve the combination of the stability of the frame body, the adaptability of the frame body to the placement position, and the stability during the transfer of the frame body.

[0006] The present invention provides a negative-pressure dust-free ton bag feeding station and its working method, which specifically includes: an equipment frame body; four first support blocks are welded at the bottom of the equipment frame body, and all four first support blocks are in contact with the ground; a feed hopper is fixed on the equipment frame body, one end of the lower part of the feed hopper is connected with a feed pipe, a first valve is installed on the feed pipe, and one end of the lower part of the feed pipe is connected with an acceleration chamber, and the acceleration chamber is welded on a negative-pressure conveying pipeline; a pneumatic air hammer is fixed on the outer wall of the feed hopper.

[0007] Further, a protective frame is fixed on the top surface of the equipment frame body, the top surface of the protective frame is higher than the feed hopper, and the protective frame is a protective member for the feed hopper.

[0008] Further, a first replenishing filter element and a second air supplementing filter element are installed on the negative-pressure conveying pipeline, and the feed hopper, the feed pipe, the first valve, the acceleration chamber, the negative-pressure conveying pipeline, the first replenishing filter element, and the second air supplementing filter element together form a feeding assembly.

[0009] Further, a purification assembly is installed on the negative-pressure conveying pipeline. The purification assembly is composed of a purification pipeline, a second valve, an air suction seat, air suction holes, and a protective seat. The purification pipeline is welded to the negative-pressure conveying pipeline and is in communication with the negative-pressure conveying pipeline. A second valve is installed on the purification pipeline. One end of the upper part of the purification pipeline is connected to the inside of the feed hopper and is in communication with the feed hopper.

[0010] Further, an air suction seat is welded to one end of the upper part of the purification pipeline. The air suction seat is located inside the feed hopper. The air suction seat is of an annular tubular structure. Air suction holes are formed in an annular array at the lower position of the outer wall of the air suction seat.

[0011] Further, a protective seat is welded inside the feed hopper. The protective seat is of an annular structure. The protective seat is located directly above the air suction seat. The protective seat is a shielding and protective member for the air suction seat.

[0012] Further, a conical groove is formed at the top of the protective seat.

[0013] Further, a support assembly is installed on the equipment frame body. The support assembly is composed of threaded rods and second support blocks. Four threaded rods are threadedly connected to the equipment frame body. A second support block is rotated at the lower end of each threaded rod.

[0014] Further, the four first support blocks are all of an L-shaped structure. The four first support blocks are all welded to the cross bar of the equipment frame body; the four first support blocks are respectively in contact with the four second support blocks; the four second support blocks are all of rectangular block structures. The four second support blocks are all located below the cross bar of the equipment frame body.

[0015] A working method of a negative-pressure dust-free ton bag feeding station includes the following steps: 01. Place the device on the ground. At this time, if the ground is not flat enough, rotate the threaded rod. Under the support of the second support block, the horizontal adjustment of the equipment frame body can be realized. 02. Suspend the bag filled with powder above the feed hopper and separate the bag. The powder in the bag enters the feed hopper. 03. Start the pneumatic air hammer to vibrate the feed hopper, thereby accelerating the falling of the powder material. 04. Open the first valve. The powder enters the feed pipe from the feed hopper, then enters the acceleration chamber, and then enters the negative-pressure conveying pipeline from the acceleration chamber. 05. The negative-pressure conveying pipeline sucks and transports the powder. At the same time, the powder scattered near the feed hopper is absorbed through the air suction seat and the air suction holes. 06. The absorbed powder enters the negative-pressure conveying pipeline through the purification pipeline for transportation. When transferring the position, place the forklift arm below the cross bar of the equipment rack body and above the second support block, and rotate the threaded rod so that the top surface of the second support block contacts the forklift arm. At this time, the position can be transferred.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Through the setting of the purification component, on the one hand, when the material moves downward in the hopper, since the material occupies the space originally occupied by the air, the air around the material is displaced, which will affect the feeding speed. At this time, through the suction of the purification pipeline and the suction seat, the extruded air can be sucked away, making the feeding smoother; on the other hand, compared with the existing device, the existing device needs to set up a separate dust suction component, which increases the equipment cost, and after the dust suction component sucks the dust, it is also necessary to add the collected dust back into the hopper again, and the operation is cumbersome. This device can suck away the floating dust during the feeding process and directly add it into the negative pressure conveying pipeline, with a more concise structure, saving cost and simplifying the operation.

[0017] Significantly improve the material handling efficiency and smoothness: By introducing a pneumatic air hammer to vibrate the feeding hopper, the falling speed of the powder material is greatly accelerated, effectively reducing the jamming and residue of the material during the feeding process, thus ensuring the continuity and high efficiency of the material transportation; this design not only improves the production efficiency, but also reduces the equipment failure rate caused by material blockage.

[0018] Comprehensively enhance the equipment protection and safety: The ingenious design of the protective frame and the protective seat provides comprehensive protection for the feeding hopper and the suction seat; the protective frame can effectively resist the impact of the falling material bag on the feeding hopper and extend the service life of the equipment; while the protective seat prevents the powder from directly hitting the suction seat, ensuring the suction efficiency and the stable operation of the equipment; these designs not only improve the durability of the equipment, but also further ensure the safety of the operators.

[0019] Optimize the filtration and purification mechanism and improve the working environment: The combined use of the first complementary filter element and the second air supplement filter element effectively filters out the impurities in the material, ensuring the purity and quality stability of the material transportation. At the same time, the purification component efficiently absorbs the floating dust around the feeding hopper through the suction holes on the suction seat, greatly reducing the impact of the dust on the health of the staff, improving the working environment and enhancing the overall operation experience.

[0020] Enhance the terrain adaptability and improve the equipment stability: The design of the support component fully considers the impact of different terrains on the equipment stability. By adjusting the heights of the threaded rod and the second support block, the horizontal adjustment of the equipment on different terrains is realized; this design not only improves the stability and applicability of the equipment, but also reduces the risk of equipment failure caused by uneven terrain.

[0021] Facilitate equipment movement and redeployment: When moving the equipment, by adjusting the threaded rod, the second support block is brought into contact with the forklift arm, ensuring the stability and safety of the equipment during transportation. This design not only simplifies the complexity of equipment handling but also improves the flexibility and efficiency of equipment redeployment.

[0022] Simplify cleaning and maintenance work: The conical groove design on the top of the protective seat helps to avoid powder residue, reducing the workload of equipment cleaning and maintenance. This design not only improves the cleanliness of the equipment but also extends the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Among them, a protective frame 101 is fixed on the top surface of the equipment frame body 1. The top surface of the protective frame 101 is higher than the feed hopper 201. The protective frame 101 is a protective part for the feed hopper 201. During use, it can prevent the material bag from falling on the feed hopper 201 and causing damage to the feed hopper 201.

[0031] Among them, a first replenishing filter element 206 and a second air supplementing filter element 207 are installed on the negative-pressure conveying pipeline 205.

A second valve 302 is installed on the purification pipeline 301. One end of the upper part of the purification pipeline 301 is connected to the inside of the feed hopper 201 and is connected to the feed hopper 201. During use, when the negative-pressure conveying pipeline 205 sucks air, the second valve 302 is opened. At this time, the purification pipeline 301 sucks air synchronously. The suction of the purification pipeline 301 can absorb the dust floating at the feed hopper 201, avoiding the dust from affecting the health of the staff.

During use, the annular suction seat 303 can expand the absorption range of floating dust, and the purification effect is better. Moreover, since the suction holes 304 are located at the lower position of the outer wall of the suction seat 303, when adding powder to the feed hopper 201, the powder will block the suction holes 304.
