Description

Technical Field

[0001] This utility model relates to the field of dust detection technology, and in particular to a cyclone dust filtration device. Background Technology

[0002] In the field of dust detection technology, dust pollution is a widespread and pressing problem. Many industries, such as chemical, metallurgical, building materials, and food processing, generate large amounts of dust during production. This dust not only severely pollutes the environment, affecting air quality and harming human health, causing respiratory diseases, but also causes wear and corrosion to production equipment, reducing equipment lifespan, increasing maintenance costs, and may even lead to explosions and other safety accidents, posing a threat to production safety.

[0003] The existing publication number CN223127510U discloses a cyclone breathing filter device for dust, including a feeding component, a distributing component at the bottom of the feeding component, a fan component on the side of the distributing component away from the feeding component, and a base component at the bottom of the fan component. The feeding component includes a feeding body, a first storage trough inside the feeding component, and a second storage trough connected to the first storage trough. The second storage trough is conical in shape, and a first feeding hole is opened at the end of the second storage trough with a smaller diameter. The fan body is connected to a motor. The motor starts the fan body, and the fan body drives the fan blades. The fan blades rotate and drive the dust to flow. The dust flows through the discharge channel and then flows through the discharge port to the dust detection position. The entire device realizes the transportation of dust. By controlling the dust flow rate and the dust flow channel, it is ensured that the dust reaches the dust detection position.

[0004] It was found that the above-mentioned device still has shortcomings in use. Firstly, although the device is connected to the first discharge hole through the smaller diameter end of the second storage tank, and the conical discharge port can effectively control the dust flow rate when the dust flows through the first discharge hole to the next detection position, preventing a large amount of dust from entering the detection position at once, and the distribution plate is equipped with partitions that allow dust to pass between adjacent partitions, and a central block is set at the center of the distribution plate to prevent dust from falling directly and affecting dust detection, the device still has shortcomings in handling high-humidity dust in actual use. Firstly, high-humidity dust is hygroscopic and easily absorbs moisture from the air inside the device, becoming damp. When this damp dust passes through the device, it will adhere to the inner wall of the device, the distribution plate, the fan blades, and other components. The adhered dust will also hinder the normal flow of air, reduce the fan's suction capacity, and thus affect the dust filtration, causing inconvenience in actual use.

[0005] Therefore, it is necessary to provide a new cyclone dust filtration device to solve the above-mentioned technical problems. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Please refer to the following: Figures 1 to 8 ,in, Figure 1 A schematic diagram of the overall structure of the cyclone dust filtration device provided by this utility model; Figure 2 A cross-sectional structural diagram of the cyclone dust filtration device provided by this utility model. Figure 3 for Figure 2 Enlarged view of point A in the middle; Figure 4 This is a schematic diagram of the material distribution tray.

[0031] Figure 5 This is a schematic diagram of the second heating element; Figure 6 This is a schematic diagram of the motor structure; Figure 7 This is a schematic diagram of the card block structure; Figure 8 This is a schematic diagram of the locking assembly.

[0032] In some embodiments, such as Figures 1 to 8As shown, the filter includes a filter body 1, a dust filter barrel 14 fixed on the top wall of the filter body 1, a cyclone diverting assembly rotatably disposed on the top wall of the filter body 1, one end of the cyclone diverting assembly extending into the dust filter barrel 14, the cyclone diverting assembly including multiple fan blades 36, multiple second heating tubes 361 fixed on the inner wall of the multiple fan blades 36, a first heating assembly fixed on the outer side of the filter body 1, and a material distribution plate 37 fixed at the bottom of the dust filter barrel 14, and the outer side of the material distribution plate 37 is fixedly connected to the inner side wall of the filter body 1.

[0033] Specifically, by fixing multiple second heating tubes 361 to the inner wall of multiple fan blades 36 of the cyclone diverter assembly, and fixing a first heating assembly to the outside of the filter barrel body 1, the inner wall of the filter barrel body 1 and multiple fan blades 36 are heated. The heating effect can reduce the moisture content of the high-humidity dust located between the first heating assembly and the second heating tubes 361, keeping the dust in a relatively dry state, greatly reducing the adhesion of dust on the fan blades 36 and the inner wall of the filter barrel body 1, and to a certain extent solving a series of problems caused by adhesion in the process of high-humidity dust treatment;

[0034] Furthermore, by fixing a filter screen barrel to the top wall of the filter barrel body 1, the heated dust, after being diverted by the cyclone and filtered by the dust filter screen barrel 14, can more effectively remove impurities and harmful substances, resulting in a purer dust product. In addition, a distribution plate 37 is fixed at the bottom of the dust filter screen barrel 14. The outer side of the distribution plate 37 is fixedly connected to the inner side wall of the filter barrel body 1 to prevent the dust from clumping again. The distribution plate 37 can disperse the dust, preventing a large amount of dust from entering the dust box 5 below the filter barrel body 1 at once due to dust re-adhesion. The dispersed distribution also facilitates subsequent dust detection and treatment.

[0035] In some embodiments, reference is made to Figure 1 , Figure 4 as well as Figure 7 As shown, the surface of the distribution plate 37 is provided with a plurality of inclined grooves 372 for distributing dust from top to bottom, and the inclination angle of the plurality of inclined grooves 372 is 45 degrees.

[0036] The angle of repose of the dust, which is the maximum angle between the inclined plane and the horizontal plane during natural accumulation, is usually 35-45 degrees. If the angle of the inclined chute is smaller than the angle of repose, the dust will easily accumulate in the chute. If the angle is too large, the dust will fall too quickly and be unevenly dispersed. The 45-degree inclined chute is just near the critical value. It can use gravity to make the dust fall down and control the falling speed through the friction of the chute wall 372. It is similar to the 45-degree anti-backflow structure of the gas inlet pipe in chemical equipment. The inclined chute 372 of the distribution plate 37 forms an airflow barrier through the inclined design. When the dust-laden airflow passes through the inclined chute, the airflow inertia will prevent the dust or liquid below from flowing back into the inclined chute 372, thereby avoiding blockage.

[0037] In some embodiments, reference is made to Figures 1 to 7 As shown, a top plate 13 is fixed to the top of the filter body 1, and a dust filter screen 14 is fixed to the bottom wall of the top plate 13. The cyclone diversion assembly also includes a fixing rod 3. The top of the fixing rod 3 is fixedly connected to the center of the bottom of the top plate 13. A cavity 31 is formed at the bottom of the fixing rod 3. A motor 311 is fixed to the top wall of the cavity 31. A connecting rod 321 is fixed to the output end of the motor 311. One end of the connecting rod 321 passes through the surface of the cavity 31 and is fixed with a rotating rod 32. A cavity 33 is formed at the bottom of the rotating rod 32. A connecting rod 34 is rotatably arranged inside the cavity 33. One end of the connecting rod 34 passes through the surface of the cavity 33 and is fixed with a pull rod 35. One end of the pull rod 35 passes through the bottom of the dust filter screen 14 and is threadedly connected with a second bolt 351. Multiple fan blades 36 are arranged around the outside of the rotating rod 32.

[0038] When the motor 311 rotates, it drives the first connecting rod 321 to rotate. The connecting rod 321 is in the shape of an I-beam, so that when the connecting rod 321 rotates at the bottom of the fixed rod 3, it will not detach from the fixed rod 3. The second connecting rod 34 is also in the shape of an I-beam, so that the second connecting rod 34 will not detach from the rotating rod 32, allowing the rotating rod 32 to rotate normally.

[0039] The dust filter screen barrel 14 has multiple filter holes 141 on its outer side. The multiple filter holes 141 are used to further filter the dust, allowing qualified dust to pass through while impurities remain inside the filter screen barrel 14. Multiple inserts 142 are fixed at the bottom of the dust filter screen barrel 14. Multiple slots 371 are opened at the top of the distribution plate 37, and the multiple inserts 142 are respectively inserted into the multiple slots 371 to achieve a snap-fit ​​and fixed connection between the dust filter screen barrel 14 and the distribution plate 37.

[0040] A storage battery 362 is fixed inside the rotating rod 32, and the storage battery 362 is electrically connected to multiple second heating tubes 361 via wires.

[0041] The first heating component includes a heating plate 2, and a plurality of first heating tubes 21 are fixed inside the heating plate 2. The plurality of heating tubes 21 are electrically connected to an external device via a wire, such as an external power supply and a temperature sensor. Preferably, in this device, a temperature sensor can be installed inside the device. The temperature sensor is used to adjust the temperature of the plurality of first heating tubes 21 and the plurality of second heating tubes 361. The method, location, model, connection method and principle of the sensor are all existing technologies and will not be described here.

[0042] The top of the top plate 13 is fixed with a feed inlet 131, which is used to introduce dust-containing gas into the device. The inner side wall of the top plate 13 is fixed with a first filter screen 132, which can perform preliminary filtration of the incoming dust and intercept larger particles of impurities. The top plate 13 and the filter barrel body 1 are fixedly connected by a first bolt 133, which facilitates the disassembly of the top plate 13 for cleaning and maintenance of the inside of the device. A sealing ring 134 is also provided between the top plate 13 and the filter barrel body 1 to ensure the sealing of the connection and prevent dust leakage.

[0043] In some embodiments, reference is made to Figure 1 as well as Figure 8 As shown, a dust box 5 is placed at the bottom of the filter body 1, and the filter body 1 and the dust box 5 are connected by a snap-fit ​​assembly.

[0044] The locking assembly includes a locking ring 4, which is sleeved on the bottom of the filter body 1. The filter body 1 and the dust box 5 are detachably connected by the locking ring 4. The surface of the locking ring 4 is provided with a buckle 41 for locking the locking ring 4. The buckle 41 adopts a transverse rotation locking method, which can easily remove the filter body 1 and the dust box 5 to clean the collected dust, thus improving the maintainability of the equipment.

[0045] The top of the filter body 1 is also fixed with a suction pipe 12, and the surface of the suction pipe 12 is also fastened with a cap 121. The cap 121 is used to open and close the suction pipe 12, and the surface of the cap 121 is provided with multiple ventilation slots. The ventilation slots are perforated and the diameter is smaller than the diameter of the required qualified dust.

[0046] Specifically, dust-laden gas enters the device through inlet 131, first undergoes preliminary filtration through first filter screen 132 to intercept larger particles, and then enters the filter barrel body 1. Motor 311 starts, driving the rotating rod 32 and fan blades 36 to rotate, forming a cyclone to divert the dust, causing the dust to rotate within the dust filter barrel 14. Simultaneously, the first heating tube 21 and the second heating tube 361 of the first heating assembly heat the inner wall of the filter barrel body 1 and the fan blades 36, respectively. The heat emitted by the filter barrel body 1 is transferred... The dust filter barrel 14 reduces the moisture content of high-humidity dust, keeping the dust dry and reducing adhesion to the inner wall of the fan blades and filter barrel body. The dried dust is filtered through the filter holes 141 on the surface of the dust filter barrel 14 under the action of the cyclone. Qualified dust continues to move downward through the filter holes 141, while impurities remain in the dust filter barrel 14. The filtered dust is dispersed by the distribution plate 37 and falls into the dust box 5 for collection. The suction pipe 12 is used to maintain communication with the external gas and maintain the airflow balance in the device.

[0047] Furthermore, a multi-stage filtration design is adopted. First, large particulate impurities are initially intercepted by the first filter screen 132, and then further filtered by the dust filter screen barrel 14. To a certain extent, a purer dust product can be obtained to meet the dust purity requirements of different industries.

[0048] Furthermore, the first heating component and the second heating tube 361 heat the inner wall of the filter barrel body 1 and the fan blade 36 respectively, effectively reducing the moisture content of the high-humidity dust and keeping the dust in a dry state. This greatly reduces the adhesion of dust to the fan blade 36 and the inner wall of the filter barrel body 1, avoiding problems such as airflow obstruction, equipment wear, and reduced filtration efficiency caused by adhesion, and extending the service life of the equipment.

[0049] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0050] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
