Description

Technical Field

[0001] The present invention relates to the technical field of dust collectors, and in particular to a heat-insulating dust collector. Background Art

[0002] A dust collector is a device used to remove dust and particulate matter generated during industrial production processes, aiming to improve air quality, protect the environment, and ensure the health of workers. It is widely used in industries such as power, steel, and chemical industries. According to its working principle and structural characteristics, dust collectors can be divided into mechanical dust collectors, wet dust collectors, filter dust collectors (such as bag dust collectors), electrostatic dust collectors, and new composite dust collectors.

[0003] Among them, bag dust collectors are widely used due to their high filtration performance. Its working principle is that when air flows through the filter cloth, dust particles are intercepted on the surface of the cloth bag, thereby achieving gas purification.

[0004] However, in actual operation, this type of dust collector faces a significant problem: due to the action of air flow, due to the large area of large-particle impurities, under the action of gas blowing, large particles will preferentially adhere to the surface of the filter cloth, forming an initial deposition layer. During this process, large particles cover the surface of the filter cloth prematurely, easily blocking the effective ventilation area of the cloth bag filter membrane quickly, resulting in blocked gas flow and thus reducing the filtration efficiency.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: An adiabatic dust collector, as Figures 1-4 shown, includes a housing 1. The housing 1 is divided into three parts, and adjacent parts are connected by bolts. The housing 1 is made of heat-insulating material and can be set as a double-layer composite structure, with aluminum silicate thermal insulation cotton filled in its interlayer. The aluminum silicate thermal insulation cotton is used for heat preservation to prevent heat transfer condensation and corrosion of the equipment. The housing 1 is provided with an air inlet and a dust discharging unit. The dust discharging unit is used to discharge the impurities accumulated at the bottom inside the housing 1 in a sealed manner during the operation of the device. A control terminal 2 and an exhaust unit 3 are installed on the housing 1. The control terminal 2 is located at the upper part of the housing 1. The exhaust unit 3 is composed of a driving fan and a guide pipe. The control terminal 2 is electrically connected to all electrical components. A first support member 4 and a second support member 5 are fixedly connected inside the housing 1. The first support member 4 is located above the second support member 5. The first support member 4 is composed of two parts. There is a chamber inside the first support member 4. The first support member 4 divides the interior of the housing 1 into two chambers, and the first support member 4 is located between the air inlet on the housing 1 and the exhaust unit 3. Twelve rotating frames 6 are rotatably arranged between the first support member 4 and the second support member 5. A filter element 7 is fixedly connected to the outside of the rotating frame 6. The rotating frame 6 and the adjacent filter element 7 form a cavity with an open upper end. A driving unit 8 is installed on the first support member 4. The driving unit 8 is composed of a driving motor and a gear set. The driving motor is installed on the upper surface of the first support member 4, and the gear set is located inside the chamber of the first support member 4. The driving unit 8 is used to drive all the rotating frames 6 and the filter elements 7 to rotate, so that some of the impurities attached to the filter element 7 can be separated under the centrifugal force, temporarily reducing the impurities attached to the filter element 7 and ensuring the air filtration efficiency of the device. A backwashing unit (simply shown in the drawing, this is an existing structure) is provided on the housing 1. The twelve rotating frames 6 are circumferentially and equidistantly distributed. There is a circular hole in the middle of the second support member 5. The twelve rotating frames 6 are located outside the circular hole on the second support member 5, and an arc-shaped inclined surface is provided on the upper surface of the second support member 5 for guiding impurities into the circular hole on the second support member 5. The minimum distance between adjacent filter elements 7 is 15 mm, and a chamber is formed in the middle of the twelve filter elements 7.

[0021] The working process of the dust collector in this embodiment is as follows: Preparation work: Connect the ventilation duct of the factory building to the air inlet on the housing 1, and then connect the exhaust unit 3 to the outside of the factory building through a pipeline.

[0022] Filtering work: First, the fan in the exhaust unit 3 is started through the control terminal 2. The exhaust unit 3 works to allow the air in the factory to enter the shell 1 through the ventilation duct. Then the air passes through the filter element 7 and enters the top of the first support member 4 from the middle of the rotating frame 6. In this process, the filter element 7 filters dust impurities in the air. The filtered air blows the control terminal 2 to cool the control terminal 2. The filtered air is discharged from the exhaust unit 3. At the same time, the fresh air system in the factory draws fresh air into the factory to complete the air circulation in the factory, and at the same time, impurities in the air are filtered and dust removed.

[0023] During the air circulation process in the workshop, the control terminal 2 starts the driving motor in the driving unit 8 at the same time. The driving unit 8 works to make all the rotating frames 6 rotate synchronously. The rotating frames 6 drive the filter elements 7 to rotate at the same time. The filter elements 7 rotate under the centrifugal effect, so that the large particles of impurities attached to them are separated. In this process, since the minimum spacing between adjacent filter elements 7 is 15 mm, the main air enters the rotating frame 6 through the outer side of the cylinder composed of twelve filter elements 7. Even if the air in the middle chamber surrounded by the twelve filter elements 7 is in a relatively static state, during the rotation of the filter element 7, the large particles of impurities after being thrown off are located in the middle chamber. Under the action of static air, the large particles of impurities gradually fall and pass through the circular holes on the second support member 5, and then the large particles of impurities are deposited at the bottom of the shell 1. After a specified amount of impurities are accumulated at the bottom of the shell 1, the ash discharge unit is started by the control terminal 2 to discharge the impurities accumulated in the shell 1. After the device works for a specified time, the exhaust unit 3 and the driving unit 8 are closed by the control terminal 2, and then the recoil unit is started to clean all the filter elements 7 in an all-round manner.

[0024] Embodiment 2: Based on embodiment 1, Figures 3-6As shown in the figure, it further includes twelve expansion units. The expansion units are arranged on adjacent rotating frames 6 and are used to keep the adjacent filter elements 7 in a taut state. The expansion unit includes six fixed rods 9 evenly distributed circumferentially (this quantity is the quantity shown in the figure, and the following quantity representations are all the quantities shown in the figure, and the actual quantity can be adjusted according to requirements). The quantity of each group of fixed rods 9 is two symmetrically arranged up and down. All the fixed rods 9 are fixedly connected to the adjacent rotating frames 6. Each group of fixed rods 9 is jointly provided with a first sliding frame 10 in a sliding manner. Two first elastic members 11 are installed between the first sliding frame 10 and the adjacent rotating frame 6. The first elastic members 11 are tension springs and are always in a stretched state. The six first sliding frames 10 are located inside the filter element 7, and the first sliding frame 10 is used to squeeze the adjacent filter element 7. A plurality of first fixing plates 12 evenly distributed are fixedly connected to the first sliding frame 10. The first fixing plates 12 are made of elastic material and are arc-shaped. The first sliding frame 10 drives the adjacent first fixing plates 12 to move and squeeze the adjacent filter element 7, so that the filter element 7 changes from a relaxed state to a taut state. When in the taut state, the adjacent two filter elements 7 are in contact with each other.

[0025] The working process of this embodiment follows that of Embodiment 1 and is described in detail as follows: During the air circulation in the factory building, under the stretching action of the first elastic member 11, the first sliding frame 10 drives the adjacent first fixing plates 12 to squeeze the adjacent filter element 7, so that the adjacent two filter elements 7 are in contact with each other. During the synchronous rotation of the twelve filter elements 7, the adjacent two filter elements 7 rub against each other, accelerating the detachment of the impurities attached to the filter element 7. After detachment, the impurities located in the central chamber surrounded by the twelve filter elements 7 fall, and the above operation is repeated subsequently.

[0026] Embodiment 3: On the basis of Embodiment 2, as Figure 3 and Figures 5-7 shown in the figure, it further includes an adjusting unit. The adjusting unit is arranged on the housing 1 and is used to adjust the positions of all the first sliding frames 10. The adjusting unit includes two electric push rods 13 symmetrically distributed. Both of the two electric push rods 13 are installed on the inner surface of the housing 1. The telescopic ends of the two electric push rods 13 are jointly fixedly connected to a second sliding frame 14. The second sliding frame 14 penetrates through all the rotating frames 6 and is in sealed sliding connection with them. Twelve fixing blocks 15 are fixedly connected to the upper surface of the second sliding frame 14. The fixing blocks 15 are located inside the adjacent rotating frames 6. An inclined surface is provided on the upper surface of the fixing block 15. A connecting rod 16 is fixedly connected to the first sliding frame 10. The lower surface of the connecting rod 16 is hemispherical, and the connecting rod 16 is in contact with the inclined surface of the adjacent fixing block 15.

[0027] The working process of this embodiment follows that of Embodiment 2 and is described in detail as follows: During the air circulation process in the workshop, the electric push rod 13 is started through the control terminal 2. The telescopic end of the electric push rod 13 drives the second sliding frame 14 and twelve fixing blocks 15 to move. The movement of the fixing blocks 15 squeezes the adjacent connecting rods 16, causing the connecting rods 16 to drive the adjacent first sliding frames 10 to move. The movement of the first sliding frames 10 changes the squeezing degree on the adjacent filter elements 7, thereby changing the distance between two adjacent filter elements 7, controlling the amount of gas entering the middle chamber surrounded by the twelve filter elements 7, facilitating the operator to select the distance between two adjacent filter elements 7 according to the size of different particulate impurities in the air, and enabling the particulate impurities of corresponding sizes on the filter elements 7 to fall and deposit in the middle chamber surrounded by the twelve filter elements 7.

[0028] Example 4: On the basis of Example 3, as Figure 3 , Figure 5 and Figure 6 shown, it further includes twelve groups of extrusion units. The extrusion units are arranged on the first support member 4 and are used to change the shape of the adjacent filter elements 7. The extrusion unit includes a second fixing plate 17, and the second fixing plate 17 is fixedly connected to the lower surface of the first support member 4. A third sliding frame 18 is arranged on the second fixing plate 17 in a limited sliding manner. The third sliding frame 18 faces the adjacent rotating frame 6. A second elastic member 171 is installed between the third sliding frame 18 and the adjacent second fixing plate 17. The second elastic member 171 is a tension spring and is in a stretched state. A rotating rod 19 is rotatably arranged on the third sliding frame 18. The rotating rod 19 is fixedly connected with a plurality of convex rings evenly distributed. The convex rings on the rotating rod 19 are used to squeeze the adjacent filter elements 7; the plurality of convex rings on the rotating rod 19 and the plurality of first fixing plates 12 on the adjacent first sliding frames 10 are staggered. The convex rings on the rotating rod 19 squeeze the adjacent filter elements 7. Under the limiting action of the plurality of convex rings on the rotating rod 19, the filter elements 7 are bent, facilitating the detachment of impurities on the filter elements 7.

[0029] The working process of this embodiment continues from Example 3 and is described in detail as follows: During the rotation process of the filter element 7, under the elastic action of the second elastic member 171, the third sliding frame 18 drives the adjacent rotating rod 19 to move towards the direction close to the adjacent filter element 7, causing the convex rings on the rotating rod 19 to squeeze the adjacent filter element 7. Under the squeezing action of the convex rings on the rotating rod 19, the outer surface of the filter element 7 is bent. Under the bending action, the caked impurities on the filter element 7 during long-term operation are broken and cracked, facilitating the detachment of the caked impurities on the filter element 7.

[0030] Example 5: On the basis of Example 4, as Figure 2 and Figure 3As shown, a fixing sleeve 20 is fixedly connected to the lower surface of the first support member 4. The fixing sleeve 20 is located outside the twelve filter elements 7. There is a gap between the fixing sleeve 20 and the second support member 5. The gas entering from the air inlet on the housing 1 blows on the fixing sleeve 20, and the fixing sleeve 20 guides the gas to flow downward, avoiding the gas directly blowing on the filter elements 7, thereby reducing the impact force of large particle impurities on the filter elements 7; a spiral plate 21 is fixedly connected to the outer surface of the fixing sleeve 20, and the spiral plate 21 is used to guide the gas to flow spirally on the outer side of the fixing sleeve 20.

[0031] The working process of this embodiment follows that of Embodiment 4 and is described in detail as follows: During the gas flow in the housing 1, the gas flows downward along the outer surface of the fixing sleeve 20. At the same time, under the guiding action of the spiral plate 21, the flowing gas flows spirally. The spirally flowing gas blows on the outer surface of the filter elements 7, further accelerating the detachment of some of the impurities attached to the filter elements 7 and extending the effective filtration duration of the filter elements 7.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
