Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, and in particular to a kiln tail bag dust collector. Background Art

[0002] Kilns are equipment made of refractory materials for firing products, and are often used to fire some handicrafts. During the use of the kiln, the smoke generated by firing will be discharged from the tail of the kiln, so these smokes need to be treated. Generally, bag dust collectors are used in industry to treat the smoke. After the large particles in the smoke are removed by the ash hopper, speed reducer and other structures, the small particles of dust in the smoke are filtered through the dust removal bags.

[0003] When the existing kiln tail bag dust collector is in use, dust will adhere to the inner wall of the dust bag. Long-term accumulation will cause dust to accumulate and agglomerate, blocking the gaps in the dust bag, resulting in a decrease in the filtering capacity of the dust bag. At the same time, it is difficult to clean the dust adhering to the inner wall of the dust bag. Moreover, the flue gas generally contains a large amount of water vapor, and the temperature at the dust bag is relatively low. Water vapor is easily liquefied here, which will wet the dust bag and cause dust accumulation. Further, the dust will agglomerate and block the dust bag, which is not conducive to the use of the dust bag. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a kiln tail bag dust collector.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] The flapping structure comprises a sliding block slidably connected to a fixed plate, the inner wall of the mounting cavity is rotatably connected to a rotating plate, a reciprocating screw rod is rotatably connected between the sliding block and the rotating plate, a connecting plate is fixedly connected between the sliding block and the rotating plate, and the position of the connecting plate corresponds to the reciprocating screw rod, a screw rod slider is mechanically matched on the reciprocating screw rod, the screw rod slider is slidably connected to the corresponding connecting plate, a flapping plate is installed on one side of the screw rod slider, a fixed spring is fixedly connected between the flapping plate and the screw rod slider, the flapping plate faces the dust collecting bag, the rotating rod and the reciprocating screw rod are interconnected by a belt transmission assembly, and an extrusion structure is installed on the screw rod slider.

[0009] Preferably, the extrusion structure includes a mounting plate fixedly connected to the screw slider, a connecting shaft is rotatably connected to the side wall of the mounting plate, a mounting block is fixedly connected to the end face of the connecting shaft, an extrusion block 1 is fixedly connected to the mounting block, an extrusion block 2 matching the extrusion block 1 is fixedly connected to the side wall of the flapping plate, a mounting gear is fixedly sleeved on the connecting shaft, a connecting rack meshing with the mounting gear is fixedly connected to the side wall of the connecting plate, and the end faces of the extrusion block 1 and the extrusion block 2 are both rounded.

[0010] Preferably, a fixed sleeve is fixedly installed inside the dust collecting bag, and the fixed sleeve passes through the inner wall of the dust collecting bag and extends to the bottom of the dust collecting bag. A heating groove matching the rotating rod is opened on the fixed sleeve, and the rotating rod extends into the interior of the heating groove. A friction layer is fixedly installed on the outer side of the rotating rod and the inner wall of the fixed sleeve.

[0011] Preferably, a fixed gear is fixedly sleeved on the reciprocating screw rod, and a movable gear ring meshing with the fixed gear is fixedly connected to the inner wall of the installation cavity.

[0012] Preferably, an air duct is fixedly connected to the fixed shell, the air duct is located above the dust collecting plate, and a sealing flange is fixedly installed at the connection between the air duct and the fixed shell.

[0013] Preferably, a fixed clamping block is fixedly connected to the dust collecting bag, and the dust collecting bag is fixedly clamped on the dust collecting plate through the fixed clamping block.

[0014] Preferably, a guardrail is fixedly installed on the top of the fixed shell, a climbing ladder is fixedly installed on the side wall of the fixed shell, and an air outlet is opened on the fixed plate.

[0015] Preferably, a restraining sleeve is sleeved on the outer side of the fixing spring, two ends of the restraining sleeve are fixedly connected to the screw slider and the flapping plate, and the restraining sleeve is a telescopic structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The flapping plate continuously flaps the side wall of the dust bag to pat down the dust adhering to the inner wall of the dust bag. At the same time, the flapping also makes the dust in the bag loose, so that it is not easy to clump, and avoids the dust blocking the gap of the dust bag, which is conducive to the filtration of the dust bag and the subsequent cleaning of the dust bag. In addition, the flapping plate will move up and down in the process of flapping the dust bag, so that the entire dust bag can be flapped more evenly, which is more conducive to the use of the dust bag;

[0018] 2. The rotation of the rotating rod causes the friction layer on its outside to rub against the friction layer inside the fixed sleeve to generate heat. The fixed sleeve made of heat-conducting material can transfer the heat to the inside of the dust bag, so that the temperature inside the dust bag is kept at a high level, avoiding the liquefaction of water vapor at the dust bag, allowing the water vapor and air to flow to the outside of the dust bag together, effectively preventing dust and water droplets from agglomerating and agglomerating, and reducing the dust bag from getting wet;

[0019] 3. When the beating plate is beating the dust bag, the beating plate can rotate around the dust bag. During the process, the beating plate will be in contact with the dust bag for a period of time. With the rotation of the beating plate, the beating plate and the dust bag will rub against each other to further heat the dust bag. Moreover, due to the uniform beating of the beating plate, the temperature difference of different parts of the dust bag is small, which prevents the liquefaction of water vapor in a certain place in the dust bag.

DETAILED DESCRIPTION

[0029] Reference Figure 1-Figure 8 , a kiln tail bag dust collector, comprising:

[0030] A fixed shell 1 is provided, and a dust collecting plate 2 is fixedly installed inside the fixed shell 1. A dust collecting port is provided on the dust collecting plate 2, and a dust collecting bag 3 is fixedly installed at the dust collecting port. A mounting cavity 5 is provided on the inner wall of the dust collecting port. After the air enters the dust collecting plate 2, it will flow to the dust collecting plate 2 and enter the dust collecting bag 3. The dust collecting bag 3 filters the air. A fixed plate 7 is fixedly connected between the inner walls of the mounting cavity 5. A motor 8 is fixedly installed on the fixed plate 7. A rotating rod 9 is fixedly connected to the output end of the motor 8. After the motor 8 is started, its output end drives the rotating rod 9 to rotate.

[0031] The flapping structure 6 includes a sliding block 11 slidably connected to the fixed plate 7, a rotating plate 14 is rotatably connected to the inner wall of the installation cavity 5, a reciprocating screw 61 is rotatably connected between the sliding block 11 and the rotating plate 14, a connecting plate 62 is fixedly connected between the sliding block 11 and the rotating plate 14, and the position of the connecting plate 62 corresponds to the reciprocating screw 61, a screw slider 63 is mechanically matched on the reciprocating screw 61, the screw slider 63 is slidably connected to the corresponding connecting plate 62, a flapping plate 65 is installed on one side of the screw slider 63, a fixed spring 64 is fixedly connected between the flapping plate 65 and the screw slider 63, the flapping plate 65 faces the dust collecting bag 3, the rotating rod 9 and the reciprocating screw 61 are connected to each other through a belt transmission assembly 10, and an extrusion structure is installed on the screw slider 63;

[0032] When the rotating rod 9 rotates, under the action of the belt transmission assembly 10, the reciprocating screw 61 will rotate accordingly, while the screw slider 63 cannot rotate. Therefore, the screw slider 63 will reciprocate up and down when the reciprocating screw 61 rotates. The movement of the screw slider 63 drives the fixed spring 64 and the flapping plate 65 to move together, and cooperate with the extrusion structure to flap the side wall of the dust bag 3, which will adhere to the inner wall of the dust bag 3, affecting the filtering capacity of the dust bag 3, and at the same time, it is not conducive to the cleaning of the dust bag 3;

[0033] The extrusion structure includes a mounting plate 67 fixedly connected to the screw slider 63, a connecting shaft 66 is rotatably connected to the side wall of the mounting plate 67, a mounting block 69 is fixedly connected to the end face of the connecting shaft 66, an extrusion block 1 610 is fixedly connected to the mounting block 69, an extrusion block 2 612 matching the extrusion block 1 610 is fixedly connected to the side wall of the flapping plate 65, the extrusion block 1 610 squeezes the extrusion block 2 612 so that the distance of its movement is greater than the distance between the flapping plate 65 and the dust collecting bag 3, a mounting gear 68 is fixedly sleeved on the connecting shaft 66, a connecting rack 611 meshing with the mounting gear 68 is fixedly connected to the side wall of the connecting plate 62, and the end faces of the extrusion block 1 610 and the extrusion block 2 612 are both rounded to facilitate the mutual extrusion between the extrusion block 1 610 and the extrusion block 2 612;

[0034] When the screw slider 63 moves up and down, the mounting plate 67 and the connecting shaft 66 move accordingly, and the mounting gear 68 fixedly sleeved on the connecting shaft 66 also moves together. Under the cooperation of the connecting rack 611, the mounting gear 68 will rotate during the up and down movement, thereby driving the connecting shaft 66 to rotate, so that the mounting block 69 and the extrusion block 1 610 rotate together. When the extrusion block 1 610 rotates to the extrusion block 2 612, it will squeeze the extrusion block 2 612, so that the extrusion block 2 612 moves outward, driving the flapping plate 65 to move. After the extrusion block 1 610 moves to a position separated from the extrusion block 2 612, under the action of the elastic force of the fixed spring 64, the flapping plate 65 returns to its original position, thereby continuously flapping. In the process of the flapping plate 65 flapping the dust collecting bag 3, there will be a period of time when the flapping plate 65 is in contact with the side wall of the dust collecting bag 3, and the friction between the two can heat the dust collecting bag 3.

[0035] A fixed sleeve 4 is fixedly installed inside the dust bag 3. The fixed sleeve 4 is made of a material with strong thermal conductivity, such as metal. The fixed sleeve 4 penetrates the inner wall of the dust bag 3 and extends to the bottom of the dust bag 3. A heating groove matching the rotating rod 9 is opened on the fixed sleeve 4, and the rotating rod 9 extends into the interior of the heating groove. The outer side of the rotating rod 9 and the inner wall of the fixed sleeve 4 are fixedly installed with a friction layer.

[0036] When the rotating rod 9 rotates, the friction layer on the outside thereof rubs against the friction layer on the inner wall of the fixed sleeve 4, thereby generating heat to heat the air entering the dust bag 3, thereby preventing the air temperature in the dust bag 3 from being low, and the water vapor in the air from liquefying, wetting the dust bag 3, and causing dust to agglomerate, thereby clogging the dust bag 3, resulting in reduced filtering effect.

[0037] A fixed gear 12 is fixedly sleeved on the reciprocating screw rod 61, and a movable gear ring 13 meshing with the fixed gear 12 is fixedly connected to the inner wall of the installation cavity 5;

[0038] During the rotation of the reciprocating screw 61, the fixed gear 12 is driven to rotate accordingly, while the movable gear ring 13 is fixed. Therefore, the fixed gear 12 will cooperate with the movable gear ring 13 to move in a circular manner while rotating, driving the reciprocating screw 61 and the sliding block 11 to move in a circular manner accordingly, so that the flapping plate 65 can flap the side wall of the entire dust collecting bag 3 to prevent residual dust from adhering to the inner wall of the dust collecting bag 3. At the same time, the uniform flapping keeps the temperature of various parts of the dust collecting bag 3 in a relatively consistent state, avoiding the temperature at a certain place being significantly lower than that at other places, causing water vapor to gather at that place and form lumps;

[0039] An air duct is fixedly connected to the fixed shell 1, and the air duct is located above the dust collecting plate 2 to facilitate filtering of the air, and a sealing flange is fixedly installed at the connection between the air duct and the fixed shell 1 to prevent air leakage; a fixed clamping block is fixedly connected to the dust collecting bag 3, and the dust collecting bag 3 is fixedly connected to the dust collecting plate 2 through the fixed clamping block, which is convenient for the installation and removal of the dust collecting bag 3; a guardrail is fixedly installed on the top of the fixed shell 1, and a climbing ladder is fixedly installed on the side wall of the fixed shell 1. The climbing ladder can facilitate the staff to climb to the top of the fixed shell 1 to repair the device, and the guardrail plays an effect of protecting the staff;

[0040] An air outlet is provided on the fixed plate 7 to facilitate the exhaust of air; a restraining sleeve is sleeved on the outer side of the fixed spring 64, and the two ends of the restraining sleeve are fixedly connected to the screw slider 63 and the flapping plate 65, and the restraining sleeve is a telescopic structure. The restraining sleeve restrains the fixed spring 64, prevents the fixed spring 64 from bending in the vertical direction, and stabilizes the position of the flapping plate 65.

[0041] In the present invention, when the device is in use, the flue gas enters the fixed housing 1 from the air duct. After entering the dust collecting plate 2, the flue gas will flow to the dust collecting plate 2 and enter the dust collecting bag 3. The dust collecting bag 3 filters the flue gas and starts the motor 8 at the same time. After the motor 8 is started, its output end drives the rotating rod 9 to rotate. When the rotating rod 9 rotates, under the action of the belt transmission assembly 10, the reciprocating screw 61 will rotate accordingly, while the screw slider 63 cannot rotate. Therefore, the screw slider 63 will reciprocate up and down when the reciprocating screw 61 rotates. The movement of the screw slider 63 drives the fixed spring 64 and the flapping plate 65 to move together. When the screw slider 63 reciprocates up and down, the mounting plate 67 and the connecting shaft 66 move accordingly, and the mounting gear 67 fixedly sleeved on the connecting shaft 66 8 also moves together. With the cooperation of the connecting rack 611, the mounting gear 68 will rotate during the up and down movement, thereby driving the connecting shaft 66 to rotate, allowing the mounting block 69 and the extrusion block 1 610 to rotate together. When the extrusion block 1 610 rotates to the extrusion block 2 612, it will squeeze the extrusion block 2 612, so that the extrusion block 2 612 moves outward, driving the flapping plate 65 to move. After the extrusion block 1 610 moves to a position separated from the extrusion block 2 612, under the action of the elastic force of the fixing spring 64, the flapping plate 65 returns to its original position, flaps the side wall of the dust collecting bag 3, and pats the dust attached to the inner wall of the dust collecting bag 3 to avoid affecting the filtering capacity of the dust collecting bag 3, and is also conducive to cleaning the dust collecting bag 3.

[0042] Moreover, during the rotation of the reciprocating screw 61, the fixed gear 12 is driven to rotate accordingly, while the movable gear ring 13 is fixed. Therefore, the fixed gear 12 rotates and cooperates with the movable gear ring 13 to move in a circular manner, driving the reciprocating screw 61 and the sliding block 11 to move in a circular manner, so that the flapping plate 65 can flap the side wall of the entire dust collecting bag 3 to prevent residual dust from adhering to the inner wall of the dust collecting bag 3;

[0043] In addition, when the rotating rod 9 rotates, the friction layer on its outer side will rub against the friction layer on the inner wall of the fixed sleeve 4, thereby generating heat to heat the air entering the dust bag 3, to prevent the air temperature in the dust bag 3 from being low, and the water vapor in the air from liquefying, wetting the dust bag 3 while causing dust to agglomerate, thereby clogging the dust bag 3 and reducing its filtering effect. At the same time, during the process of the flapping plate 65 flapping the dust bag 3, there will be a period of time when the flapping plate 65 is in contact with the side wall of the dust bag 3. The friction between the two can heat the dust bag 3, so that the temperature of each part of the dust bag 3 is maintained in a relatively consistent state, to avoid the temperature at a certain place being significantly lower than that at other places, causing water vapor to gather at that place and form agglomerates, which is beneficial to the use of the dust bag 3.
