Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to dust removal equipment for a melting and casting furnace. Background Art

[0002] Melting furnaces are widely used in the processing of smelting metal aluminum. A large amount of smoke and dust will be generated in the process of smelting aluminum. At present, dust removal equipment is used in the industry to filter and purify the smoke before discharge. The more common dust removal equipment in the casting industry is pulse bag dust removal.

[0003] However, after long-term use, the filter bags of the pulse bag dust collector will slowly adhere to layers of dust. In the prior art, a blowing system is usually used to blow high-pressure air directly to the filter bags through the nozzles on the blowing pipe, so that the dust on the surface of the filter bags can be cleaned under the action of the airflow. However, blowing high-pressure air to the same place on the filter belt for a long time may cause the place to bear impact force for a long time, which is prone to damage and reduces the service life of the filter bags. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] The utility model provides an air guide hood, and the wind blown by the spraying mechanism is dispersed by the air guide holes on the air guide hood and then blown onto the filter bag, so that the dust on the surface of the filter bag falls into the dust accumulation hopper. The air guide hood rotates on the rotating seat with the wind to adjust the air outlet position, so that the wind can evenly spray the filter bag, avoiding long-term spraying at a fixed position that may cause damage to the filter bag, thereby effectively maintaining the service life of the filter bag.

[0017] The utility model provides a reciprocating component, and drives the rotating disk to rotate by a driving motor. Since the center of rotation is not located at the center of the rotating disk, the rotating disk will push the sliding frame close to it to one side when it rotates. When the rotating disk rotates to the other side, the squeezed return spring will return the pushed out sliding frame to its original position. In this way, the reciprocating motion drives the impact head to impact the inner wall of the box body, so that the dust attached to the inner wall of the box body is shaken off, thereby ensuring the cleanliness of the inside of the box body.

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

[0024] In the embodiment, Figure 1-4 A dust removal device for a melting furnace is provided, comprising a box body 1, a blowing mechanism 2 is arranged at the top inner part of the box body 1, a mounting plate 3 located below the blowing mechanism 2 is fixedly installed inside the box body 1, a plurality of through holes 4 are opened on the mounting plate 3, a filter bag 5 located outside the through hole 4 is fixedly installed at the bottom of the mounting plate 3, an air guide hood 6 located outside the through hole 4 is arranged inside the filter bag 5, a dust isolation box 7 is arranged inside the box body 1, a reciprocating assembly 8 with both ends penetrating and extending to the outside of the dust isolation box 7 is arranged inside the dust isolation box 7, impact assemblies 9 are arranged at both ends of the reciprocating assembly 8, and a ash hopper 10 is arranged at the bottom inner part of the box body 1.

[0025] Reference Figure 2-3 , wherein the blowing mechanism 2 includes an air inlet pipe 21, the top of the mounting plate 3 is fixedly mounted with the air inlet pipe 21 connected to the outside, and the bottom of the air inlet pipe 21 is equidistantly mounted with a plurality of air jet heads 22, and the plurality of air jet heads 22 all penetrate the through hole 4 and extend to the inside of the air guide cover 6;

[0026] Through the above-mentioned structural arrangement, the gas enters the interior of the box body 1 along the air inlet pipe 21 and then is ejected through the nozzle 22 to clean the dust attached to the filter bag 5 and make the dust fall into the dust hopper 10 .

[0027] Reference Figure 2-3 , wherein a plurality of air guide holes 61 are provided on the outer side and the bottom of the air guide cover 6, and the plurality of air guide holes 61 are evenly distributed on the air guide cover 6, and the air guide cover 6 is rotatably mounted on the mounting plate 3 through a rotating seat 62;

[0028] With the above-mentioned structural arrangement, when the blowing mechanism 2 is working, when the airflow enters the air guide cover 6, the airflow is blown out along the air guide holes 61 on the surface, so that the airflow is dispersedly blown on the filter bag 5, and at the same time drives the air guide cover 6 to rotate on the rotating seat 62, so as to prevent the fixed position of the filter bag 5 from being blown by the airflow for a long time, which affects the service life.

[0029] Reference Figure 2-4 , wherein the reciprocating assembly 8 includes a driving motor 81, the driving motor 81 is fixedly installed inside the dust isolation box 7, a rotating disk 82 is fixedly installed at the output end of the driving motor 81, the connection between the rotating disk 82 and the driving motor 81 is located below the center of the rotating disk 82, positioning frames 83 are fixedly installed on both sides of the rotating disk 82, and sliding frames 84 are slidably installed on both sides of the rotating disk 82, one end of which penetrates the positioning frame 83 and extends to the outside of the dust isolation box 7, and a return spring 85 connected to the positioning frame 83 is installed on the outside of the sliding frame 84;

[0030] Through the above-mentioned structural arrangement, the driving motor 81 drives the rotating disk 82 to rotate. Since the center of rotation is not located at the center of the rotating disk 82, the rotating disk 82 will push the sliding frame 84 close to it to one side when rotating. When the rotating disk 82 rotates to the other side, the squeezed return spring 85 will return the pushed out sliding frame 84 to its original position, and thus perform reciprocating motion.

[0031] Reference Figure 2-4 , wherein the impact assembly 9 includes a connecting seat 91, the top of the sliding frame 84 is fixedly mounted with the connecting seat 91, one end of the connecting seat 91 is fixedly mounted with a vibration spring 92, and one end of the vibration spring 92 is fixedly mounted with an impact head 93;

[0032] With the above-mentioned structural arrangement, when the sliding frame 84 moves to one side, it drives the impact head 93 to impact the inner wall of the box body 1 , thereby shaking off the dust attached to the inner wall of the box body 1 .

[0033] Working principle:

[0034] The first step to implement the innovation point:

[0035] Step 1: When the smoke generated during smelting is sucked into the box 1, after being adsorbed and purified by the filter bag 5, a large amount of dust will be attached to the filter bag 5 and needs to be cleaned. At this time, the blowing mechanism 2 is started, and the gas enters the box 1 along the air inlet pipe 21, and then is ejected through the nozzle 22 into the air guide cover 6. When the airflow enters the air guide cover 6, the airflow is blown out along the air guide holes 61 on the surface, so that the airflow is dispersed and blown on the filter bag 5, and at the same time, the air guide cover 6 is driven to rotate on the rotating seat 62, so as to avoid the fixed position of the filter bag 5 being blown by the airflow for a long time, which affects the service life, and the dust attached to the filter bag 5 is cleaned and the dust falls into the dust hopper 10;

[0036] Step 2: At the same time, the rotating disk 82 is driven to rotate by the driving motor 81. Since the center of rotation is not located at the center of the rotating disk 82, the rotating disk 82 will push the sliding frame 84 close to it to one side when rotating. When the rotating disk 82 rotates to the other side, the squeezed return spring 85 will return the pushed out sliding frame 84 to its original position. In this way, the reciprocating motion drives the impact head 93 to hit the inner wall of the box body 1, and the dust attached to the inner wall of the box body 1 is shaken off.
