Description

Technical Field

[0001] The utility model relates to the technical field of automobile production unloading, in particular to a dust removal device for unloading vehicles in front of a warehouse. Background Technique

[0002] When using an automobile to transport production materials into the factory area for production, when unloading a large amount of materials, due to the materials and the factory environment itself, a certain degree of dust will be generated, which will not only affect the environment, but also affect production and the health of workers. With the formulation and popularization of the new air pollutant emission standards for thermal power plants, the emission standards for dust in the production environment are more strictly controlled. Therefore, in order to maintain the production environment, it is necessary to purify the dust generated at the unloading position.

[0003] Traditional dust removal methods mostly set up a closed space at the place where dust removal is required and use a dust removal hood to remove dust in the space. However, in the production site, multiple vehicles need to unload at the same time. If multiple closed spaces are manufactured, the cost is high and the floor area is large. At the same time, when using multiple dust removal hoods for dust removal, the pressure and flow rate in the dust removal hood are very important parameters affecting the dust removal effect. In order to save costs, in actual use, multiple dust removal hoods usually share a total dust collector. Therefore, when sharing a total dust collector, if all are opened at the same time, it is difficult to ensure the pressure and flow rate in each dust removal hood at the same time to ensure better dust removal effect. If manual control is adopted, it is time-consuming and laborious to adjust by manpower, and the requirement for labor cost is also high. Therefore, a dust removal device with a high degree of automation during vehicle unloading is needed, which can control and adjust each dust removal hood, improve the dust absorption effect while reducing resource waste, reducing power consumption and reducing labor. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a dust removal device for unloading vehicles in front of a warehouse with a high degree of automation, which can control and adjust each dust removal hood, ensure the pressure and flow rate in each dust removal hood, and at the same time ensure the dust removal effect, reduce power consumption and reduce labor costs.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a dust removal device for unloading vehicles in front of a warehouse, including a total dust collector, a chimney is connected behind the total dust collector for treating the absorbed dust, multiple unloading positions in front of the warehouse are provided for vehicles transporting materials to unload, a dust removal hood is arranged in the air above the rear of each unloading position in front of the warehouse, the dust inlet of the dust removal hood is inclined downward and aligned with the unloading vehicle, the dust outlet at the end of each dust removal hood is connected to the main pipeline of the dust collector, a photoelectric switch for detecting whether a vehicle enters the unloading position in front of the warehouse is arranged on one side of each unloading position in front of the warehouse, and an electric valve for controlling whether the dust outlet at the end of each dust removal hood is connected to the main pipeline is arranged at the connection between the dust outlet at the end of each dust removal hood and the main pipeline, and the electric valve and the total dust collector are controlled by the photoelectric switch.

[0006] A further improvement of the technical solution of the present utility model lies in that: on the other side of each front unloading position of the bin, an ion sprayer is provided, and the nozzle of the ion sprayer hangs in the air and is arranged above the front unloading position of the bin.

[0007] A further improvement of the technical solution of the present utility model lies in that: the ion sprayer is controlled by a photoelectric switch.

[0008] A further improvement of the technical solution of the present utility model lies in that: the photoelectric switch is a diffuse reflection photoelectric switch.

[0009] A further improvement of the technical solution of the present utility model lies in that: the electric valve is an electric butterfly valve.

[0010] A further improvement of the technical solution of the present utility model lies in that: the dust removal hood is a horn-shaped dust removal hood.

[0011] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model is as follows: by setting a photoelectric switch on one side of the front unloading position of the bin, detecting whether there is a vehicle unloading at the position through the photoelectric switch, and then turning on and off the dust removal hood valve and the dust collector, it can effectively replace manual control of the switch and reduce labor costs. By setting an electric valve at the position where the dust removal hood is connected to the main pipeline, it is usually closed so that the dust removal hood is not connected to the main pipeline. Only when the dust removal hood is working, the electric valve is opened to connect to the main pipeline. In this way, a total dust collector does not always provide suction to each dust removal hood in real time, making it difficult to meet the pressure and flow standards in each dust removal hood. Only the working dust removal hood is connected to the main pipeline, and the number of dust removal hoods that the dust collector bears at the same time is small, which can effectively ensure the pressure, flow rate, filtration air velocity, etc. in each dust removal hood and ensure the dust removal effect. By setting the dust removal hood in the air with the dust inlet inclined downward, the dust removal range is larger. Combined with negative ion spraying, negative ions can better combine with the dust to achieve dust reduction, and after dust reduction, it is better removed by the dust removal hood.

[0015] The present invention is further described in detail below in conjunction with the embodiments:

[0016] Embodiment 1

[0017] like Figure 1 The figure shows a schematic diagram of the structure of a dust removal device for unloading vehicles in front of a warehouse, which includes a main dust collector 1, and a chimney 2 is connected to the back of the main dust collector 1 to process the dust absorbed during the dust removal process. A plurality of unloading positions 3 in front of the warehouse are planned and arranged in front of the warehouse in the factory area. When the vehicle 6 transporting materials transports the materials, it drives to the unloading position 3 in front of the warehouse to unload the materials. A dust hood 4 is arranged in the air above and behind each unloading position 3 in front of the warehouse. The dust hood 4 is trumpet-shaped, and the large dust inlet is tilted downward and aimed at the unloading vehicle 6. The dust outlet at the rear end of each dust hood 4 is connected to the main pipeline 11 of the main dust collector 1. An independent photoelectric switch 5 is arranged on one side of each unloading position 3 in front of the warehouse, which is only used to detect whether the vehicle 6 enters the current unloading position 3 in front of the warehouse for unloading. The dust outlet at the rear end of each dust hood 4 and the connection point of the main pipeline 11 are all provided with an electric valve 41 for controlling whether the rear end of the dust hood 4 and the main pipeline 11 are connected. In this embodiment, the electric valve adopts an electric butterfly valve. The electric valve 41 of the dust hood 4 on each parking space and the main dust collector 1 are controlled by the photoelectric switch 5 on the current parking space. The photoelectric switch 5 is a diffuse reflection photoelectric switch with a transmitting end and a receiving end in one place. When the photoelectric switch 5 on a certain parking space detects that there is a vehicle 6 in the current parking space for unloading, the photoelectric switch 5 controls the opening of the electric valve of the dust hood 4 and the main dust collector 1 on the parking space. The main dust collector 1 is turned on, and the current dust hood 4 is connected to the main pipeline 11. The dust collector 1 only provides suction to the currently opened dust hood 4 for dust removal, ensuring the pressure flow and filtering wind speed in the dust hood 4, and ensuring a better dust removal effect.

[0018] Embodiment 2

[0019] This embodiment adds an ion sprayer 7 on the basis of the first embodiment, because the dust volume is not particularly huge when the factory unloads, and it is difficult to create multiple relatively closed spaces in the factory, so that the vehicle is unloaded in a closed space to ensure the best dust removal effect on dust during unloading. Therefore, it is still chosen to unload on the parking space in the open space. In order to ensure the dust removal effect of unloading in the open space, the dust cover 1 is set in the air, and the opening is tilted downward to ensure a larger adsorption range during dust removal. At the same time, an ion sprayer 7 is set on the other side of the parking space and the photoelectric switch 5. The nozzle of the ion sprayer 7 is suspended in the air and is set above the front side of the unloading space 3 in front of the warehouse. At the same time, the ion sprayer 7 is also controlled by the photoelectric switch 5. When the photoelectric switch 5 detects that there is a vehicle unloading at the unloading space 3 in front of the warehouse, the dust cover 4 valve is opened, and the ion sprayer 7 is also opened. The nozzle sprays ion spray, which can better combine with dust to achieve dust reduction. Even if unloading is carried out in an open area, the dust removal effect can be guaranteed to a certain extent.

[0020] This new type can strengthen the control and adjustment of each dust hood of the dust collector during use, improve the dust collection effect, save power consumption and human resources, and effectively maintain production.

[0021] The embodiments described above are only used to describe the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
