Description

Technical Field

[0001] This utility model relates to the field of chemical storage tanks, specifically to a storage tank with a dust suppression device. Background Technology

[0002] In the field of chemical product storage and transportation, storage tanks, as important material storage equipment, often face the problem of dust diffusion during the discharge process. When traditional storage tanks discharge, the induced airflow generated by the free fall of material carries a large amount of dust particles, creating diffuse dust pollution. This situation not only causes material loss (especially with high-value-added fine chemicals), but also leads to PM2.5 exceeding standards in the working environment, endangering the respiratory safety of operators. Existing technologies mostly employ simple baghouse dust collection or open-type spray dust suppression solutions. The former is prone to filter clogging due to the static charge adsorption of materials, while the latter alters the material's properties (such as moisture absorption and agglomeration), making it difficult to achieve sealed, non-contact dust control. Furthermore, conventional discharge ports lack adaptive sealing structures, easily generating secondary dust when connecting to transport containers of different sizes. Moreover, clearing blockages requires stopping the machine and disassembling parts, severely impacting continuous production.

[0003] Therefore, in order to solve the above-mentioned problems, a storage tank with a dust suppression device is proposed. Utility Model Content

[0004] This utility model addresses the problems mentioned above by designing a storage tank with a dust suppression device. This device can absorb the dust generated during material discharge through an adsorption device, and can also assist in installing the bag opening, generating suction at the bag opening, and assist in fastening the bag opening to fix it. The components work together to avoid the health hazards of dust generated during material discharge to workers and improve the quality of the workshop working environment.

[0005] To achieve the above objectives, this utility model provides a storage tank with a dust suppression device, comprising: a receiving cylinder, an adsorption device, and a fastening device. The receiving cylinder is fixedly connected to the side of the discharge cylinder below the tank body. The adsorption device is sleeved on the receiving cylinder and connected to an exhaust fan. The fastening device is fixed to the end of the adsorption device away from the discharge cylinder and located at the end of the receiving cylinder.

[0006] In the above manner, the receiving cylinder is used to discharge materials from the tank, the packaging bag is attached to the end of the receiving cylinder, and the adsorption device is used to absorb the dust generated by the material poured into the packaging bag during the discharge process. At the same time, when the packaging bag is attached to the receiving cylinder, the suction can generate suction on the opening of the packaging bag, which facilitates the subsequent fastening device to clamp the packaging bag.

[0007] Furthermore, the adsorption device includes: an adsorption ring, a suction hole, a vent pipe, and a flow guide hood. The adsorption ring is a hollow annular structure and is sleeved on the outer ring of the receiving cylinder. The suction hole is provided on the adsorption ring. The flow guide hood is a frustoconical structure. The smaller diameter end of the flow guide hood is fixedly connected to the end of the adsorption ring away from the discharge cylinder. The receiving cylinder is placed inside the flow guide hood. The vent pipe is fixedly connected to the adsorption ring and communicates with the exhaust fan.

[0008] In this way, the cavity inside the adsorption ring provides a place for air circulation, the vent pipe transmits the suction force to the designated position through the air intake hole, and the guide hood limits the area of ​​air intake, making the air force more concentrated and improving the dust collection effect.

[0009] Furthermore, the fastening device includes: an outer ring frame, telescopic fixing rods, and a tightening head. The outer ring frame is fixedly connected to the end of the flow guide shroud away from the adsorption ring. There are several telescopic fixing rods, which are evenly distributed and fixedly connected to the side of the outer ring frame. The end of each telescopic fixing rod is fixedly connected to the tightening head, which is in contact with the outer surface of the receiving cylinder.

[0010] In this way, the outer frame is located at the end of the receiving cylinder, which can easily fix the bag opening of the packaging bag fitted at the end. The telescopic fixing rod is an electric telescopic rod structure, which can press the packaging bag tightly at the end of the receiving cylinder through the tightening head at the end.

[0011] Furthermore, it also includes a sealing door, which is disposed inside the discharge cylinder.

[0012] Furthermore, the closed door includes an opening and closing door panel and an operating rod. There are two opening and closing door panels. The discharge cylinder has a long groove located at the upper part of the receiving cylinder. The operating rod is fixedly connected to the opening and closing door panel and is slidably connected in the long groove.

[0013] Furthermore, the closed door also includes a protrusion, and the two opening and closing door panels are provided with the protrusion at one adjacent end, and the two protrusions are arranged in an overlapping manner.

[0014] Using the above method, the sliding operating lever opens the closed door to both sides, allowing for the opening and closing of the feeding cylinder and convenient control of the feeding weight. The protrusions provide a better sealing effect.

[0015] Furthermore, it also includes a blockage-clearing device, which is disposed inside the receiving cylinder.

[0016] Furthermore, the unblocking device includes a handwheel and a baffle. The baffle has a circular plate structure, and its end is connected to the handwheel. The handwheel is rotatably disposed on the side of the receiving cylinder.

[0017] In this way, when the material in the feed cylinder becomes clogged due to excessive material density, the baffle can be rotated to agitate the material and prevent clogging.

[0018] In summary, this utility model has the following advantages and beneficial technical effects:

[0019] 1. The present invention provides a storage tank with a dust suppression device that can absorb dust generated during material discharge through an adsorption device, and can also assist in the installation of the bag opening, generating suction force on the bag opening, and assist in the fastening device to fix the bag opening. The components work together to avoid the harm of dust generated during material discharge to the health of workers, and also improve the quality of the workshop working environment.

[0020] 2. The storage tank with dust suppression device of this utility model achieves self-sealing through the overlapping double door panel structure and the principle of geometric interference, which can better play the role of stopping the transportation of materials;

[0021] 3. The storage tank with dust suppression device of this utility model can prevent the pipe from being blocked during material feeding through the anti-blocking device, and can also temporarily shut down the pipe. Attached Figure Description
