Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaning devices, in particular to unorganized emission treatment equipment. Background Art

[0002] With the improvement of environmental awareness and the increasingly stringent environmental regulations, the control of unorganized emissions has become an important area of ​​air pollution control. In order to effectively control unorganized emissions, reduce air pollutant emissions, and protect the ecological environment and public health, unorganized emission control equipment has come into being. The application range of unorganized emission control equipment is wide, including steel, chemicals, building materials, electricity, coal and other industries. These industries will produce a large amount of waste gas, dust and other pollutants in the production process. If they are not effectively controlled, they will have a serious impact on the atmospheric environment. Unorganized emission control equipment can effectively collect and treat these pollutants by adopting advanced dust removal technology, filtration technology, adsorption technology and other means, thereby reducing the emission of air pollutants and improving environmental quality.

[0003] The prior art has the following shortcomings in actual use: First, in traditional unorganized emission control equipment, dust collectors (such as dust suction ports, dust suction tubes, etc.) are mostly made of hard materials. When these materials are in contact with air containing particulate matter for a long time, they will wear out rapidly due to friction, which not only reduces the service life of the dust collectors, but also may lead to a decrease in the dust collection effect or even equipment failure; Second, when dealing with unorganized emissions containing a large amount of dust and particulate matter, the dust collectors are easily blocked. The blocked dust collectors will not only lead to a decrease in dust collection efficiency, but also may cause equipment overheating, damage and other problems. The blocked dust collectors usually need to be shut down for cleaning, which not only affects the working efficiency of the equipment, but also may cause losses to production, especially when dealing with materials with high viscosity and easy to clump, the dust collectors are more likely to be blocked and more difficult to clean.

[0004] How to invent an unorganized emission control device to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1, refer to Figure 1-Figure 2 , a kind of unorganized emission treatment equipment, including a vacuum pump 1, a primary dust collector 2 and a secondary dust collector 201, the secondary dust collector 201 is connected to the upper end of the primary dust collector 2, the lower end of the primary dust collector 2 is connected with a collecting end 4, the number of the primary dust collector 2 and the secondary dust collector 201 are both two and the two secondary dust collectors 201 are connected, one side of one of the secondary dust collectors 201 is connected to the vacuum pump 1 by a flange with a connecting pipe 3, composed of two sets of dust removal and filtration systems and double material tanks, the first stage is a sedimentation and separation dust collector, the dust removal efficiency Above 85%, it is mainly used to collect larger particles of powder. The second stage is a filtering and purifying dust collector. The dust removal efficiency is above 99.9%. A double-tank system structure is adopted. The negative pressure dust suction equipment can realize continuous work without stopping the machine. The continuous operation during the working process can realize centralized unloading and automatic continuous ash discharge. The ash discharge process does not stop. A plurality of branch pipes 401 are arranged inside the collecting end 4. The end of the branch pipe 401 is connected with a plastic hose 5. The inner side of the end of the plastic hose 5 is sealed with a collecting grip pipe 6. The end of the collecting grip pipe 6 is installed with a dust collecting component;

[0027] It should be noted that the end of the branch pipe 401 extends to the inside of the collecting end 4 and is located above the central axis of the collecting end 4. The branch pipe 401 is welded to the collecting end 4, which is convenient for assembly and disassembly and ensures the air tightness of the device.

[0028] Reference Figure 3-Figure 6The dust collecting assembly includes a connecting head 7 and a dust collecting plate 8. Both sides of the connecting head 7 are fixedly connected with mounting plates 701. Mounting holes are correspondingly provided on the mounting plates 701 and the upper side walls of the dust collecting plate 8. The connecting head 7 is installed on the dust collecting plate 8 through mounting bolts, which is convenient for disassembling and cleaning the dust collecting plate 8. The interiors of the connecting head 7 and the dust collecting plate 8 are both hollow. The ends of the collecting grip tubes 6 are fixedly inserted into the interior of the connecting head 7. The cross-section of the dust collecting plate 8 is trapezoidal, which is convenient for pushing the ash layer. Mounting grooves 802 are provided on both sides of the dust collecting plate 8. A transmission shaft 901 is rotatably connected to the dust collecting plate 8. The ends of the transmission shaft 901 pass through the side walls of the dust collecting plate 8 and extend to the interior of the mounting groove 802. A roller 9 is fixedly connected to the transmission shaft 901 located in the interior of the mounting groove 802. The friction between the dust collecting plate 8 and the ash layer can be effectively reduced by the roller 9. An eccentric block 902 is fixedly connected to the transmission shaft 901 located inside the dust collecting plate 8.

[0029] It should be noted that: a connecting filter plate 702 is installed at the port of the connecting head 7 close to the dust collecting plate 8, which can preliminarily filter the dust entering the collecting grip tube 6. A plurality of dust collecting ports 801 are provided at the bottom end of the dust collecting plate 8. The ends of the dust collecting ports 801 penetrate the bottom wall of the dust collecting plate 8 to suck in the dust. The dust collecting ports 801 are expanded outward from the inner cavity to expand the suction range. The transmission shaft 901 is located at the center of the dust collecting plate 8. The diameter of the roller 9 is greater than the height of the dust collecting plate 8, which is convenient for adjusting the position of the dust collecting plate 8. Adjustment is made so that there is a gap between the proximal end of the eccentric block 902 and the bottom wall of the filter plate 702 or the bottom wall of the dust collecting plate 8, and the distance between the central axis of the transmission shaft 901 and the distal end of the eccentric block 902 is greater than half of the height of the inner cavity of the dust collecting plate 8. By such an arrangement, when the roller 9 rotates, the transmission shaft 901 can drive the eccentric block 902 to impact and clear the dust collecting port 801 at the bottom of the dust collecting plate 8 and the blocked through holes on the filter plate 702, and the auxiliary negative pressure suction can also crush large pieces of dust in the dust collecting plate 8 by impact.

[0030] Embodiment 2: In practical applications, the fugitive emission treatment equipment needs to be able to adapt to a variety of different working environments and ground conditions. In order to improve the adaptability and flexibility of the equipment, the collection grip tube 6 can be replaced with a collection end 601 (refer to Figure 7 ), taking into account the interchangeability between the collection grip tube 6 and the collection end 601, this design allows the user to select the most suitable collection method according to the specific working conditions and ground conditions. The collection grip tube 6 is generally suitable for a relatively flat or standardized working environment. It can provide a stable dust collection effect and is easy to operate. However, in some special cases, such as when the ground is uneven, there are obstacles, or when precise dust collection is required in a specific area, the collection grip tube 6 may not meet the needs. The collection end 601 (refer to Figure 7) is designed to solve these special situations. It can better adapt to irregular ground or bypass obstacles, and is equipped with suction ports of different shapes and sizes to adapt to dust sources of different sizes and types. Through this replaceable design, users can flexibly choose the collection grip tube 6 or the collection end 601 according to actual needs, thereby ensuring that the equipment can achieve the best dust removal effect under various working conditions, and then be compatible with different working conditions and match different ground conditions.

[0031] The working principle of the unorganized emission treatment equipment is as follows: start the vacuum pump 1. After the vacuum pump 1 is started, negative pressure is generated to provide power for the dust suction and dust removal process of the entire system. The dust in the working environment is sucked into the collection end 4 through the collecting grip tube 6 or the collecting end 601 (according to the second embodiment), and the connected plastic hose 5 and the branch pipe 401. The sucked dust first enters the primary dust collector 2, where larger particles of dust are mainly removed by sedimentation and separation, and the dust removal efficiency is above 85%. The gas after the primary dust removal enters the secondary dust collector 201, where tiny particles are further removed by filtering and purification, and the dust removal efficiency is above 99.9%. Due to the use of a double-tank system structure, the equipment can work continuously without stopping, realizing centralized unloading and automatic continuous ash discharge. The dust content of the gas after the two-stage dust removal has been greatly reduced and can be safely discharged into the atmosphere.

[0032] The connector 7 is fixed to the dust collecting plate 8 by a mounting bolt. This design allows the connector 7 to be easily removed from the dust collecting plate 8, making it easy to clean and maintain. The trapezoidal cross-section design of the dust collecting plate 8 helps to push the ash layer, so that the dust forms a certain accumulation on the dust collecting plate 8, which is convenient for subsequent collection and treatment. The design of the roller 9 and the eccentric block 902 on the transmission shaft 901 reduces the friction between the dust collecting plate 8 and the ash layer by rotation, making the dust collecting plate 8 smoother when pushing the ash layer. The dust collecting port 801 is located at the bottom of the dust collecting plate 8 and is responsible for collecting dust inhaled from the working environment. The through holes on the filter plate 702 allow gas to pass through while blocking dust particles to play a filtering role. The rotational movement of the eccentric block 902 generates periodic impact forces, which act on the dust collecting port 801 at the bottom of the dust collecting plate 8 and the through holes on the filter plate 702, which helps to clear the channels that may be blocked and ensure the smooth flow of air. The design of the dust collecting plate 8 takes into account the convenience of maintenance and can be easily disassembled for cleaning to ensure the long-term and effective operation of the equipment.

[0033] In summary, the fugitive emission control equipment can effectively collect and treat dust in the working environment, reduce fugitive emissions, and protect the environment and the health of workers.
