[0029] Embodiment 1

[0030] Refer to Figures 1 to 6, which is the first embodiment of the present invention, provides a movable boiler fly ash negative pressure cleaning device. This device includes a box body 1. At the top of the inner cavity of the box body 1, a filter bag 2 is provided. On one side of the bottom of the inner cavity of the box body 1, a Roots blower 3 is fixedly installed. On the outside of the Roots blower 3, a device switch controller 4 is fixedly installed.

[0031] Specifically, through the coordinated cooperation of the filter bag 2 and the Roots blower 3 arranged in the box body 1, a complete negative pressure dust collection system is constructed. Among them, the filter bag 2 adopts a modular and replaceable design, which is convenient for operators to carry out regular maintenance and cleaning operations, effectively solving the technical problem of difficult maintenance of traditional fixed filter devices; the integrated design of the device switch controller 4 realizes the one-key start and stop control of the system, significantly improving the operation convenience of the device, enabling the entire system to quickly respond to the operation requirements of the industrial site, not only ensuring the efficient collection of fly ash, but also greatly reducing the maintenance cost of the device.

[0032] Further, a connecting intake pipe 5 is provided below the filter bag 2. One end of the connecting intake pipe 5 is connected to one side of the Roots blower 3.

[0033] Among them, by setting the connecting intake pipe 5, an optimized air flow channel is established between the Roots blower 3 and the filter bag 2, ensuring the stable transmission of negative pressure air flow, enabling fly ash to be evenly adsorbed on the inner surface of the filter bag 2, effectively avoiding the phenomenon of air flow disorder, significantly improving the dust separation efficiency. At the same time, this structural design enables the system to control the energy consumption within a reasonable range while maintaining a high dust collection efficiency, achieving the balanced optimization of performance and energy consumption.

[0034] Preferably, an exhaust pipe 6 is fixedly installed at the end of the Roots blower 3, and an air outlet 7 is provided at the end of the exhaust pipe 6.

[0035] Among them, the cooperative design of the exhaust pipe 6 and the air outlet 7 constitutes an efficient exhaust system. This structure ensures that the filtered clean air can be discharged smoothly. The special structural design of the air outlet 7 has two advantages. On the one hand, it effectively reduces the air flow noise and improves the working environment; on the other hand, it cleverly prevents the backflow of external dust, maintains the air pressure balance inside the system, significantly improves the operation stability of the device, and extends the service life of key components.

[0036] Further, a fully automatic air compressor 8 is fixedly installed on the outside of the box body 1. One side of the box body 1 is hinged with a rear cover 9, and a connecting pipe head 10 is fixedly installed on the outside of the rear cover 9.

[0037] Among them, the introduction of the fully automatic air compressor 8 realizes the automatic cleaning function of the filter bag 2. Through the pulse airflow flapping controlled by the program, it effectively prevents the blockage problem caused by excessive accumulation of ash layer on the surface of the cloth bag. The hinged design of the rear cover 9 and the standardized interface of the connecting pipe head 10 not only realize the quick opening and closing function of the equipment, but also enable the system to flexibly expand the dust collection operation range, suitable for cleaning fly ash at high places and far away, greatly improving the equipment's working condition adaptability.

[0038] Furthermore, a hydraulic rod 11 is hinged on the outer side of the rear cover 9, and the bottom of the hydraulic rod 11 is hinged on the outer side of the box body 1 for opening the rear cover 9.

[0039] Among them, the mechanical linkage design of the hydraulic rod 11 realizes the automatic opening and closing function of the rear cover 9. This structure ensures the smooth and reliable operation through hydraulic drive, completely replacing the traditional manual operation method. It can automatically complete the opening action of the rear cover 9 during the unloading operation, significantly improving the operation efficiency. At the same time, the buffering characteristics of the hydraulic system effectively avoid mechanical impact, extend the service life of the equipment, and reduce the maintenance frequency.

[0040] Furthermore, a high-pressure belt motor 12 is fixedly installed on the other side of the bottom of the inner cavity of the box body 1, and an openable steel door 13 is arranged in the inner cavity of the box body 1 and at the top of the filter bag 2.

[0041] Among them, the power system design of the high-pressure belt motor 12 provides continuous and stable power output for the equipment, ensuring the long-term operation of the negative pressure dust collection system. The innovative design of the openable steel door 13 provides a convenient channel for equipment maintenance, enabling operators to quickly complete the replacement of the filter bag 2 and the cleaning of the inside of the box body 1, greatly shortening the equipment maintenance time and improving the comprehensive utilization efficiency of the equipment.

[0042] Furthermore, an observation window 14 is fixedly installed on the outer side of the box body 1, and a heat dissipation perforated iron net 15 is fixedly installed on the inner cavity of the box body 1 and on the side close to the high-pressure belt motor 12.

[0043] Among them, the observation window 14 made of thickened tempered glass provides operators with a clear internal observation field of view, facilitating real-time monitoring of the fly ash collection volume in the bin. The scientific layout of the heat dissipation perforated iron net 15 forms an efficient heat dissipation channel, providing a good heat dissipation environment for the high-pressure belt motor 12, ensuring both operation safety and the continuous and stable operation of the equipment, and significantly improving the reliability of the equipment.

[0044] Furthermore, a rotary control port 18 is provided on the outer side of the box body 1 to adjust the strength of sucking fly ash. Guardrails 19 are provided around the top of the box body 1. A high-strength steel panel 20 is fixedly installed on the outer surface of the box body 1, and rectangular tubes 21 are cross-installed on the outer side of the high-strength steel panel 20.

[0045] Among them, the innovative design of the rotary control port 18 realizes the stepless adjustment function of the ash suction strength. The suction force can be accurately controlled through a simple rotation operation. This adjustment mechanism has a clear corresponding relationship. The larger the opening of the window, the smaller the suction force, and the smaller the opening, the larger the suction force. This design enables the equipment to flexibly adapt to the needs of different working conditions and optimize the energy consumption control while ensuring the operation effect; the combined design of the guardrail 19 and the high-strength steel panel 20 significantly improves the overall structural strength of the equipment, enabling it to adapt to various harsh industrial environments. The cross-installation of the rectangular tubes 21 further enhances the rigid structure of the box body 1 and effectively prevents deformation problems caused by long-term use.

[0046] It should be noted that this cleaning equipment adopts a vehicle-mounted design and can be conveniently installed on a small truck or a special adapter vehicle for flexible mobile operation. This mobile equipment is powered by a vehicle-mounted power system, adopts an aviation socket power interface design, and is equipped with an industrial-grade waterproof and dustproof aviation plug and socket assembly to ensure continuous and stable power supply during the movement and dumping operations of the equipment. The entire system adopts a fully enclosed negative pressure dust suction structure, and a high-efficiency negative pressure dust suction system is composed of a filter bag 2 and a Roots blower 3 arranged inside the box body 1. It is combined with a water mist dust suppression barrier formed by the dustproof water spray pipe 17 to ensure that dust does not leak during the mobile cleaning process. This mobile design enables the equipment to quickly reach different working points such as power plant boilers and dust collectors, realizing efficient and environmentally friendly fly ash cleaning operations, meeting the strict requirements of modern industry for mobile environmental protection equipment;

[0047] This equipment adopts a fully enclosed negative pressure dust suction system to form a sealed negative pressure space inside the box body 1. Through the coordinated action of the filter bag 2 and the Roots blower 3, efficient collection of fly ash is achieved. When the system operates, fly ash is sucked into the equipment interior in a completely enclosed environment. Combined with the water mist dust suppression barrier formed by the dustproof water spray pipe 17 above the rear cover 9, it is ensured that there is no dust leakage during the entire operation process, and the dust emission concentration is controlled within 10mg / m 3 The following meets the environmental protection requirements of industrial cleaner production.

[0048] During use, first, start the high-pressure belt motor 12 through the equipment switch controller 4 to drive the Roots blower 3 to operate, forming a negative pressure environment inside the box body 1; then the operator adjusts the suction strength through the rotary control port 18, so that fly ash is sucked into the system through the connecting pipe head 10 and the gas-solid separation is completed inside the filter bag 2;

[0049] The clean air is discharged through the exhaust duct 6 and the air outlet 7, while the collected fly ash is deposited at the bottom of the box body 1; the fully automatic air compressor 8 regularly performs pulse back blowing and dust cleaning on the filter bag 2 to prevent blockage; when discharging is required, the hydraulic rod 11 automatically opens the rear cover 9 to complete the ash discharging operation, and at the same time, the dust-proof water spraying pipe 17 starts to suppress dust;

[0050] The operator can monitor the working status in real time through the observation window 14 and perform maintenance through the openable steel door 13. The entire system operates stably with the assistance of the heat dissipation hollow iron net 15, realizing the efficient, safe, and automated cleaning of fly ash.

[0051] In summary, through the negative pressure dust collection system composed of the filter bag 2 and the Roots blower 3 in the box body 1, the efficient collection and filtration of fly ash are realized. The modular and replaceable filter bag 2 design significantly improves the maintenance convenience. The connecting air inlet pipe 5 optimizes the air flow channel, ensuring uniform dust adsorption and reducing energy consumption. The exhaust system composed of the exhaust duct 6 and the air outlet 7 maintains the air pressure balance and reduces noise; the fully automatic air compressor 8 cooperates with the pulsed air flow to prevent the filter bag 2 from being blocked. The hinged design of the rear cover 9 and the connecting pipe head 10 expand the operation range. The hydraulic rod 11 realizes the automatic opening and closing of the rear cover 9, improving the discharging efficiency. The high-pressure belt motor 12 provides stable power. The openable steel door 13 is convenient for maintenance. The observation window 14 and the heat dissipation hollow iron net 15 respectively optimize the monitoring and heat dissipation performance. The rotary control port 18 realizes stepless suction adjustment. The guardrail 19, the high-strength steel panel 20, and the cross-shaped square tubes 21 enhance the rigidity and durability of the equipment. The overall structure adapts to the harsh industrial environment, significantly improving the automation degree, operation efficiency, and safety of fly ash cleaning, while reducing the maintenance cost and energy consumption.

[0052] Embodiment 2

[0053] Refer to Figure 4 , this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is: the dust-proof water spraying pipe 17 for reducing the dust pollution when the rear cover 9 is opened.

[0054] Furthermore, a maintenance ladder 16 is fixedly installed on the outer side of the rear cover 9, and a dust-proof water spraying pipe 17 is horizontally installed on the outer side of the box body 1 and above the rear cover 9.

[0055] Among them, the user-friendly design of the maintenance ladder 16 provides a safe and convenient climbing channel for the high-altitude maintenance operation of the equipment. The connection system between the dust-proof water spraying pipe 17 and the vehicle body water tank constitutes an effective dust suppression device. The water spraying mode can be turned on during the discharging operation to form a water mist barrier, effectively suppressing the dust pollution generated when the fly ash is dumped. This environmental protection design fully meets the requirements of modern industrial clean production.

[0056] During use, when the hydraulic rod 11 is activated to open the rear cover 9 for discharging operations, the dust-proof water spray pipe 17 is synchronously and automatically activated. Through the water supply system connected to the vehicle body water tank, a uniform and fine water mist barrier is formed above the discharging area; this water mist barrier effectively wraps the falling fly ash particles and significantly suppresses dust generation through the principle of wet settlement.

[0057] In summary, by horizontally installing the dust-proof water spray pipe 17 above the rear cover 9, this device is connected to the vehicle body water tank to form an intelligent dust suppression system. When discharging operations are carried out, the water spraying mode is automatically activated, forming a uniform and fine water mist barrier that effectively wraps and settles the fly ash particles generated during the dumping process, significantly reducing dust pollution; at the same time, the maintenance ladder 16 added to the outside of the rear cover 9 adopts a non-slip ladder design, providing a safe and convenient maintenance passage. This improvement not only meets the requirements of environmental protection production but also enhances the convenience of equipment maintenance.
