Description

Technical Field

[0001] This utility model relates to the field of port dust suppression technology, specifically to a dust suppression system for port tippers. Background Technology

[0002] A tippler is a large mechanical device used to unload bulk materials from open railway wagons. It is a loading and unloading machine that can tilt or tilt rail vehicles to unload materials.

[0003] When unloading, tippers directly dump the materials in the truck bed, resulting in significant dust accumulation on site. To achieve environmental protection goals, dust suppression systems are typically employed. Existing conventional dust suppression systems include water mist or dry fog systems, but neither type offers satisfactory dust suppression performance, leading to low reliability and failing to meet actual dust suppression requirements. Utility Model Content

[0004] This utility model provides a dust suppression system for port tippers to solve at least one of the above-mentioned technical problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A dust suppression system for a port tipper includes a spraying device, a control device, and a dust detection device. The spraying device includes a mixing container, the inlet of which is connected to a water source via a first pipe, and the inlet of which is also connected to a constant temperature raw material storage unit via a second pipe, the constant temperature raw material storage unit storing a bio-nanofilm preparation; the outlet of the mixing container is connected to a spraying unit via a third pipe; a first solenoid valve is installed on the first pipe, a second solenoid valve is installed on the second pipe, and a third solenoid valve is installed on the third pipe; The first solenoid valve, the second solenoid valve, the third solenoid valve, the spray unit, and the dust detection device are electrically connected to the control device.

[0006] Compared with the prior art, the present invention has at least the following beneficial effects: The dust suppression system provided by this invention effectively improves the dust suppression effect of water mist by mixing biofilm preparations with water. By setting up a dust detection device to acquire dust data from the work area, the control device can control the opening and closing states of the first and second solenoid valves based on the dust data, thereby controlling the mixing ratio of the biofilm preparations and water. This improves the dust suppression effect of water mist based on the biofilm preparations while avoiding waste and reducing consumption of the biofilm preparations. The use of a constant-temperature raw material storage unit to store the biofilm preparations ensures that they are stored at the optimal temperature, avoiding problems such as protein denaturation, reduced activity, and slowed microbial metabolism.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] In one possible implementation, the constant temperature raw material storage unit includes a raw material storage box, a temperature detection device is installed inside the raw material storage box, the raw material storage box is connected to a heating / cooling device, and the temperature detection device and the heating / cooling device are electrically connected to the control device respectively.

[0009] The advantages of the above scheme are: the internal temperature of the raw material storage box is kept constant by a temperature detection device and a heating / cooling device. The structure is simple, the control is convenient, and it is suitable for various biological nanofilm preparations.

[0010] In one possible implementation, both the mixing container and the raw material storage box are multi-layer composite insulation structures.

[0011] The beneficial effects of the above scheme are: using a multi-layer composite insulation structure to manufacture the mixing container and the raw material storage box can delay the direct impact of temperature changes on the mixing container and the raw material storage box, thereby ensuring the stability of the biofilm preparation.

[0012] In one possible implementation, the multi-layer composite insulation structure includes an outer shell and an inner shell, with a filling cavity between the outer shell and the inner shell, and the filling cavity is filled with phase change material spheres.

[0013] The beneficial effects of the above scheme are: by using phase change material spheres to fill the cavity between the outer shell and the inner shell, the phase change properties of the phase change material spheres can better maintain the temperature stability of the mixing container and the raw material storage box, thereby ensuring the stability of the bio-nanofilm formulation.

[0014] In one possible implementation, the total volume of the phase change material spheres accounts for 30%-50% of the volume of the filling cavity.

[0015] The beneficial effects of the above scheme are: by controlling the proportion of the total volume of the phase change material spheres in the filling cavity, a capacity margin is provided for the volume change of the phase change material spheres during the phase change process, thus ensuring the stability of the mixing container and raw material storage box structure.

[0016] In one possible implementation, the mixing container is equipped with a stirrer, which is electrically connected to the control device.

[0017] The beneficial effects of the above scheme are: by setting up a stirrer, the biofilm preparation and water can be mixed more evenly, and the temperature uniformity of the mixture can also be ensured, thereby ensuring the activity of the biofilm preparation.

[0018] In one possible implementation, the outer surfaces of the second and third pipes are provided with heat tracing tapes, which are electrically connected to the control device.

[0019] The beneficial effect of the above scheme is that by setting up a heating cable to heat the second pipe and the third pipe, the second pipe and the third pipe can be kept at a suitable temperature for the biofilm preparation, thus making it suitable for cold environments.

[0020] In one possible implementation, the spray unit includes several spray branch pipes connected to the third pipe, and each spray branch pipe is provided with several spray heads at intervals.

[0021] The beneficial effect of the above scheme is that by laying out the spray branch pipes, the spraying device can cover the entire working area of ​​the tipper, ensuring the dust suppression effect.

[0022] In one possible implementation, the spray branch pipe is connected to an air supply unit via a fourth pipe, and a fourth solenoid valve is installed on the fourth pipe. The air supply unit and the fourth solenoid valve are electrically connected to the control device, respectively.

[0023] The beneficial effects of the above solution are: by setting up an air supply unit to supply air to the spray branch pipe after the spraying operation is completed and spray it out from the spray head, it can prevent dust in the work area from entering the spray head and conveying branch pipe and causing blockage, thus ensuring the smooth flow of the spray head and conveying branch pipe.

[0024] In one possible implementation, a pressurizing device is also provided on the third pipeline, and the pressurizing device is electrically connected to the control device.

[0025] The beneficial effects of the above scheme are: by setting up a pressurizing device, greater pressure is provided to the spray branch pipe, thereby making the coverage of the spray head wider and saving biofilm preparations. Attached Figure Description

[0028] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] Example like Figure 1 As shown, this utility model embodiment provides a dust suppression system for a port tipper, including a spraying device, a control device 1, and a dust detection device 2; The spraying device includes a mixing container 3, the inlet of which is connected to a water source via a first pipe 4, and the inlet of the mixing container 3 is also connected to a constant temperature raw material storage unit via a second pipe 5, which stores a bio-nanofilm preparation; the outlet of the mixing container 3 is connected to a spraying unit via a third pipe 6; a first solenoid valve 7 is installed on the first pipe 4, a second solenoid valve 8 is installed on the second pipe 5, and a third solenoid valve 9 is installed on the third pipe 6; The first solenoid valve 7, the second solenoid valve 8, the third solenoid valve 9, the spray unit, and the dust detection device 2 are electrically connected to the control device 1.

[0030] The dust suppression system provided in this embodiment of the invention effectively improves the dust suppression effect of water mist by mixing biofilm preparations with water. By setting up a dust detection device 2 to acquire dust data of the working area, the control device 1 can control the opening and closing states of the first solenoid valve 7 and the second solenoid valve 8 according to the dust data, thereby controlling the mixing ratio of biofilm preparations and water. While improving the dust suppression effect of water mist based on biofilm preparations, the system avoids waste of biofilm preparations and reduces their consumption. The biofilm preparations are stored in a constant temperature raw material storage unit, which keeps the biofilm preparations at the optimal storage temperature and avoids problems such as protein denaturation, reduced activity, and slowed microbial metabolism.

[0031] It should be noted that the control device 1 in the embodiments of this utility model may be, but is not limited to, a controller with data processing function such as a microcontroller, microcomputer or PLC, as long as it has the ability to identify data and control the operation of the device. No limitation is made here.

[0032] The dust detection device 2 in this embodiment of the present invention may, but is not limited to, use a dust concentration sensor, such as a PMS5003 sensor, a PMSA003 sensor, a ZH03B sensor, or a GP2Y1010AU0F sensor, etc., and is not limited here.

[0033] The biofilm preparations described in this embodiment of the present invention may be, but are not limited to, microbial extracellular polymer-based biofilm preparations, composite biofilm preparations, etc., and are not limited herein.

[0034] like Figure 1 As shown, in one feasible implementation, the constant temperature raw material storage unit in this embodiment of the present invention includes a raw material storage box 10, a temperature detection device 11 is provided inside the raw material storage box 10, and a heating / cooling device 12 is connected to the raw material storage box 10. The temperature detection device 11 and the heating / cooling device 12 are electrically connected to the control device 1 respectively.

[0035] This embodiment of the invention uses a temperature detection device 11 and a heating / cooling device 12 to maintain a constant temperature inside the raw material storage box. It has a simple structure, is easy to control, and is suitable for various biological nanofilm preparations with different temperature requirements.

[0036] It should be noted that the temperature detection device 11 in this embodiment of the present invention may, but is not limited to, using a temperature sensor, such as a PT100 sensor, a K-type thermocouple sensor, etc., and is not limited here.

[0037] The heating / cooling device 12 in this embodiment of the present invention may, but is not limited to, use a TEC module. The TEC module is small in size, vibrates-free, and can achieve precise temperature control.

[0038] like Figure 2 As shown, in one feasible implementation, the mixing container 3 and the raw material storage box 10 in this embodiment of the present invention may, but are not limited to, employ a multi-layer composite insulation structure. Using a multi-layer composite insulation structure to manufacture the mixing container and the raw material storage box can delay the direct impact of temperature changes on the mixing container and the raw material storage box, thereby ensuring the stability of the biofilm formulation.

[0039] like Figure 2As shown, in one feasible implementation, the multi-layer composite insulation structure of this utility model may include, but is not limited to, an outer shell 101 and an inner shell 102, with a filling cavity between the outer shell 101 and the inner shell 102, filled with phase change material spheres 103. By filling the filling cavity between the outer shell 101 and the inner shell 102 with phase change material spheres 103, at higher temperatures, the phase change material spheres 103 undergo a phase change from solid to liquid, absorbing and storing a large amount of latent heat during the melting process. At lower temperatures, the phase change material spheres 103 undergo a reverse phase change from liquid to solid, releasing latent heat. This better maintains the temperature stability of the mixing container and the raw material storage tank, thereby ensuring the stability of the internal biofilm formulation.

[0040] It should be noted that the phase change material sphere 103 in the embodiments of this utility model may be, but is not limited to, organic phase change material spheres, such as paraffin hydrocarbons, or inorganic phase change materials, such as hydrated salts, etc., which are not limited here.

[0041] like Figure 2 As shown, in one feasible implementation, the total volume of the phase change material spheres 103 in this embodiment of the present invention can be controlled, but is not limited to, to occupy 30%-50% of the filling cavity volume. By controlling the proportion of the total volume of the phase change material spheres in the filling cavity, a capacity is provided to accommodate the volume changes of the phase change material spheres during the phase change process, ensuring the stability of the mixing container and raw material storage box structure.

[0042] In one feasible implementation, the mixing container 3 in this embodiment of the present invention may be equipped with a stirrer, which is electrically connected to the control device 1.

[0043] By incorporating a stirrer, this embodiment of the invention enables more uniform mixing of the biofilm preparation and water, and also ensures the temperature uniformity of the mixture, thereby protecting the activity of the biofilm preparation.

[0044] It should be noted that the stirrer in the embodiments of this utility model may be, but is not limited to, a magnetic stirrer, and is not limited here.

[0045] In one feasible implementation, the outer surfaces of the second pipe 5 and the third pipe 6 in this embodiment of the present invention are provided with heat tracing tape, which is electrically connected to the control device 1.

[0046] This embodiment of the invention uses a heating cable to heat the second pipe 5 and the third pipe 6, enabling the second pipe 5 and the third pipe 6 to maintain a suitable temperature for the biofilm preparation, thus making it suitable for cold environments.

[0047] It should be noted that the heat tracing cable in this embodiment of the present invention may be, but is not limited to, a constant power heat tracing cable or a self-regulating heat tracing cable, and is not limited here.

[0048] In one feasible implementation, the spray unit in this embodiment of the present invention includes a plurality of spray branch pipes 13 connected to the third pipe 6, and a plurality of spray nozzles 14 are arranged at intervals on each spray branch pipe 13.

[0049] This embodiment of the invention, through the arrangement of the spray branch pipes 13, enables the spraying device to cover the entire working area of ​​the tipper, ensuring the dust suppression effect.

[0050] It should be noted that the spray head 14 in the embodiments of this utility model may be, but is not limited to, an adjustable angle spray head.

[0051] In one possible implementation, the spray branch pipe 13 is connected to the air supply unit 16 via the fourth pipe 15, and the fourth solenoid valve 17 is provided on the fourth pipe 15. The air supply unit 16 and the fourth solenoid valve 17 are electrically connected to the control device 1, respectively.

[0052] This embodiment of the utility model provides an air supply unit 16 to supply air to the spray branch pipe 13 after the spraying operation is completed, and the air is sprayed out from the spray head 14. This can prevent dust in the working area from entering the spray head and the conveying branch pipe and causing blockage, thus ensuring the smooth flow of the spray head and the conveying branch pipe.

[0053] In the specific implementation process, since the tipper is in an indoor working environment, the smoke and dust are not easy to disperse. Therefore, the air supply unit 16 in this embodiment of the utility model can be, but is not limited to, an oil-lubricated rotary screw air compressor. The oil-lubricated rotary screw air compressor is used to compress air and supply it to the spray unit through the fourth pipe 15.

[0054] In one possible implementation, the third pipe 6 in this embodiment of the invention is further provided with a pressurizing device 18, which is electrically connected to the control device 1. By providing the pressurizing device, greater pressure is provided to the spray branch pipe, thereby expanding the coverage area of ​​the spray head and saving biofilm preparations.

[0055] It should be noted that the pressurizing device 18 in this utility model embodiment may be, but is not limited to, a conventional pressurizing device, such as the SCALA2 series pressurizing device, the PAH / HI series pressurizing device, etc., and is not limited here.

[0056] The working principle of the dust suppression system for port tippers provided in this embodiment of the invention is as follows: Temperature detection device 11 detects the temperature value inside raw material storage box 10 in real time and sends it to control device 1. When the temperature value is greater than the set threshold range, control device 1 controls heating / cooling device 12 to cool down the temperature inside raw material storage box 10 to the set threshold range. When the temperature value is less than the set threshold range, control device 1 controls heating / cooling device 12 to heat up the temperature inside raw material storage box 10 to the set threshold range. When the temperature value is within the set threshold range, control device 1 controls heating / cooling device 12 to be in the off state.

[0057] When there is a work task, the dust detection device 2 acquires dust data of the work area and sends it to the control device 1. The control device 1 controls the opening and closing status and opening value of the first solenoid valve 7 and the second solenoid valve 8 according to the dust data, so that the first set amount of biofilm preparation and the second set amount of water enter the mixing container 3. The control device 1 controls the first solenoid valve 7 and the second solenoid valve 8 to be in the closed state. The control device 1 turns on the stirrer to stir, so that the biofilm preparation and water are mixed evenly to obtain a mixture. The proportion of biofilm preparation in the mixture is within the required range, and the proportion of biofilm preparation in the mixture is directly proportional to the dust concentration value.

[0058] When mixing is finished, the control device 1 controls the agitator to stop working, and at the same time controls the third solenoid valve 9 and the pressurizing device 18 to open, and controls the fourth solenoid valve 17 to close. The pressurizing device 18 pressurizes the mixture and then transports it to the spraying unit through the third pipeline 6 for spraying operations, thereby suppressing dust in the work area.

[0059] When there is no work to be done, the control device 1 controls the first solenoid valve 7, the second solenoid valve 8, the third solenoid valve 9, the dust detection device 2 and the pressurization device 18 to be closed, and controls the air supply unit 16 and the fourth solenoid valve 17 to be opened. The air supply unit 16 compresses the air and then delivers it to the spray unit through the fourth pipe 15 to prevent dust in the work area from entering the spray unit and causing blockage.
