Description

Technical Field

[0001] This utility model relates to the field of ton-bucket filling technology, and in particular to a ton-bucket filling exhaust hood. Background Technology

[0002] IBCs (Liquid Tank Units) are lightweight, high-strength, and corrosion-resistant, making them widely used in various industries. They are essential tools for modern warehousing and transportation of liquid products. Using IBCs for packaging can significantly reduce production, storage, transportation, and operating costs, saving a lot of manpower and resources. They are widely used in the chemical, electronics, starch, and brewing industries, as well as in water treatment and purification equipment, secondary water supply systems in high-rise buildings, water storage, and the storage and transportation of various chemical raw materials, oils, and beverages.

[0003] During the filling operation of ton containers, the filling is carried out by inserting a conveying pipe into the mouth of the ton container. During the filling process, some harmful gases escape from the mouth of the ton container, which can easily pollute the air quality and have a certain impact on the operators. Therefore, it is necessary to extract and remove the escaped harmful gases. In the existing technology, exhaust hoods are usually suspended at a high position to extract and remove harmful gases. However, the exhaust hoods are far away from the mouth of the ton container and cannot cover the gaps around the mouth of the ton container. It is difficult to completely prevent the escape of polluted airflow, and there is a significant risk that some harmful gases will diffuse into the surrounding air. The effect of capturing harmful gases is not good. At the same time, the exhaust hoods are not easy to move and cannot be flexibly used according to different usage locations.

[0004] Therefore, it is necessary to provide a vent hood for ton-barrel filling to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a vent hood for ton-bucket filling to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: a ton-bucket filling exhaust hood, comprising a conveying pipe and an exhaust hood, wherein an insertion port is provided at one end of the exhaust hood, the conveying pipe passes through the insertion port and is inserted into the mouth of the ton-bucket, and an annular air intake port is provided inside the exhaust hood to draw air from all sides; a cavity communicating with the annular air intake port is provided inside the other end of the exhaust hood; a connecting sleeve is fixed on the outer wall of the exhaust hood, and an exhaust pipe communicating with the cavity is fixed inside the connecting sleeve; and a flow guiding component located inside the insertion port is provided inside the exhaust hood.

[0007] As a further embodiment of this utility model, the airflow guiding component includes at least one triangular prism, which is disposed inside the inlet to prevent excessive wind speed on the side near the exhaust pipe.

[0008] As a further embodiment of this invention, the angle between the exhaust pipe and the horizontal plane is set between 45° and 60° to reduce air suction resistance.

[0009] As a further embodiment of this utility model, a rubber cylinder is fixed on the outer wall of the exhaust hood, and the rubber cylinder is arranged coaxially with the inlet.

[0010] As a further embodiment of this utility model, the outer wall of the rubber cylinder is provided with rubber ribs, and there are multiple rubber ribs that are equidistantly distributed.

[0011] As a further embodiment of this utility model, the inner diameter of the insertion port is larger than the diameter of the conveying pipe and smaller than the diameter of the ton barrel opening.

[0012] As a further embodiment of this utility model, a handle is fixed to one end of the exhaust hood.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The airflow escaping from the opening of the ton container is drawn in through the annular suction port and enters the exhaust pipe through the cavity. The exhaust pipe then draws the gas away. During this process, the annular suction port ensures uniform airflow around the opening of the ton container, effectively capturing toxic and harmful airflows escaping from the opening during the filling process. The annular design maximizes the suction area, greatly reducing the phenomenon of excessively high or low local wind speeds, thereby improving the airflow capture efficiency and effectively preventing diffusion to the surrounding environment, ensuring workplace safety and hygiene. Compared with the local exhaust hoods in the prior art, this utility model can cover the gaps around the opening of the ton container, more comprehensively preventing the escape of polluted airflow, and achieving better and more efficient capture of harmful gases. 2. The exhaust hood can be easily removed, making it convenient for operators to move and use, thus allowing for flexible use in different locations; 3. The airflow guiding components can guide the airflow smoothly to the air intake, preventing the formation of eddies or concentrated airflow, reducing airflow disturbance, ensuring uniform air intake, and avoiding direct impact of airflow on the edge of the air intake, thereby reducing noise and energy loss and improving the energy efficiency of the exhaust system.

[0016] The present invention will be further described below with reference to the embodiments.

[0017] Please see Figure 1-5 This utility model provides a ton-bucket filling exhaust hood, including a conveying pipe 3 and an exhaust hood 1. An insertion port 5 is provided at one end of the exhaust hood 1, through which the conveying pipe 3 passes and is inserted into the mouth of the ton-bucket. An annular suction port 12 is provided inside the exhaust hood 1, surrounding the insertion port 5, for circumferential air intake. A cavity 11 communicating with the annular suction port 12 is provided inside the other end of the exhaust hood 1. A connecting sleeve 8 is fixed to the outer wall of the exhaust hood 1, and an exhaust pipe 2 communicating with the cavity 11 is fixed inside the connecting sleeve 8. The exhaust hood 1 is equipped with a flow guide component 9 located inside the inlet 5. This utility model is mainly used for ventilation and protection of the opening of the ton container 4 when conveying materials into it. The exhaust pipe 2 is connected to an external air pump, and negative pressure is generated in the exhaust pipe 2 and the annular suction port 12. During use, the conveying pipe 3 passes through the inlet 5 and is inserted into the opening of the ton container 4 to fill the ton container 4 with materials. The airflow escaping from the opening of the ton container 4 is drawn in by the annular suction port 12 and enters the exhaust pipe 2 through the cavity 11. The airflow is then discharged through the exhaust pipe 2. The system draws air out of the container. During this process, the annular suction port 12 ensures uniform airflow around the opening of the container, effectively capturing toxic and harmful airflows escaping from the opening during the filling process. The annular design maximizes the suction area, significantly reducing local wind speeds that are too high or too low, thereby improving airflow capture efficiency and effectively preventing diffusion to the surrounding environment, ensuring workplace safety and hygiene. Compared with existing partial exhaust hoods, this invention can cover the gaps around the opening of the container, more comprehensively preventing the escape of polluted airflow, achieving better and more efficient capture of harmful gases. Furthermore, the exhaust hood 1 can be easily removed for convenient operation and flexible use depending on the location. The guide component 9 guides the airflow smoothly towards the suction port, preventing eddies or concentrated wind speeds, reducing airflow disturbance, ensuring uniform suction, and preventing direct impact of airflow on the suction port edge, thus reducing noise and energy loss and improving the energy efficiency of the exhaust system.

[0018] Further as Figure 4 As shown, it is worth noting that the airflow guiding component 9 includes at least one triangular prism 91, which is located inside the inlet 5 to prevent excessive wind speed on the side near the exhaust pipe 2. The airflow guiding function of the triangular prism 91 is based on its geometry, which can disperse and smoothly guide the airflow to the center of the air intake. Its edges can guide the airflow to turn smoothly, avoid the airflow directly impacting the edge of the air intake, reduce eddies and turbulence, thereby reducing noise and energy loss, and improving the removal effect of toxic and harmful airflow.

[0019] Further as Figure 5 As shown, it is worth noting that the angle between the exhaust duct 2 and the horizontal plane is set between 45° and 60° to reduce suction resistance. In actual operation, the angle between the exhaust duct 2 and the horizontal plane is controlled between 45° and 60°. This angle range is based on the principle of fluid mechanics. When the airflow enters the exhaust duct 2, the angle of 45° to 60° allows the airflow to transition smoothly, which can optimize the airflow direction, avoid eddies and pressure drops caused by right-angle turns, reduce the impact and friction loss of the airflow in the pipe, reduce the local resistance coefficient and noise, and improve the energy efficiency of the exhaust system.

[0020] Further as Figure 5 As shown, it is worth noting that a rubber cylinder 6 is fixed on the outer wall of the exhaust hood 1, and the rubber cylinder 6 is arranged coaxially with the inlet 5. When in use, the inlet 5 is aligned with the opening of the ton container 4, and the rubber cylinder 6 is pressed into the opening of the ton container 4. The elastic deformation of multiple rubber ribs 7 increases the friction between the rubber cylinder 6 and the side wall of the opening of the ton container 4, so that the exhaust hood 1 is fixed at the opening of the ton container 4, which facilitates use. At the same time, the exhaust hood 1 can be easily removed, which is convenient for operators to move and use, so that it can be used flexibly according to different usage locations.

[0021] This solution has the following working process: Align the inlet 5 with the opening of the ton container 4, and press the rubber cylinder 6 into the opening of the ton container 4. The elastic deformation of multiple rubber ribs 7 increases the friction between the rubber cylinder 6 and the side wall of the ton container 4, so that the exhaust hood 1 is fixed at the opening of the ton container 4. The conveying pipe 3 passes through the inlet 5 and is inserted into the opening of the ton container 4 to fill the ton container 4 with materials. The annular suction port 12 has a negative pressure. The airflow escaping from the opening of the ton container 4 is drawn in by the annular suction port 12 and enters the exhaust pipe 2 through the cavity 11. The gas is then drawn away by the exhaust pipe 2. During this process, the annular suction port 12 achieves uniform airflow around the opening of the ton container, effectively capturing the toxic and harmful airflow escaping from the opening during the filling process. The triangular prism 91 acts as a guide, which can disperse and guide the airflow smoothly, reducing eddies and turbulence.

[0022] Further as Figure 5 As shown, it is worth noting that rubber ribs 7 are provided on the outer side wall of the rubber cylinder 6. There are multiple rubber ribs 7, and the multiple rubber ribs 7 are distributed at equal intervals. The elastic deformation of the multiple rubber ribs 7 increases the friction between the rubber cylinder 6 and the side wall of the barrel opening of the ton 4, thereby improving the stability of the exhaust hood 1.

[0023] Further as Figure 1 and Figure 2 As shown, it is worth noting that the inner diameter of the spigot 5 is larger than the diameter of the conveying pipe 3 but smaller than the diameter of the opening of the ton container 4.

[0024] Further as Figure 2 and Figure 3 As shown, it is worth noting that a handle 10 is fixed on one end of the exhaust hood 1; the handle 10 makes it easy to pick up the exhaust hood 1 and make it convenient to use.

[0025] In summary: The annular air intake 12 achieves uniform air intake around the opening of the ton container, effectively capturing toxic and harmful airflows escaping from the container opening during the filling process. The annular design maximizes the air intake area, significantly reducing localized high or low wind speeds, thereby improving airflow capture efficiency and effectively preventing diffusion to the surrounding environment, ensuring workplace safety and hygiene. Compared with existing partial exhaust hoods, this invention can cover the gaps around the opening of the ton container 4, more comprehensively preventing the escape of polluted airflows, achieving better and more efficient capture of harmful gases. Furthermore, the exhaust hood 1 can be easily removed for convenient operation and flexible use depending on the location. The guide component 9 guides the airflow smoothly towards the air intake, preventing eddies or concentrated wind speeds, reducing airflow disturbance, ensuring uniform air intake, and preventing direct impact of airflow on the edge of the air intake, thus reducing noise and energy loss and improving the energy efficiency of the exhaust system.

[0026] The air pump can be purchased from the market. The air pump is equipped with a power supply. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be described again in the instruction manual.
