Description

Technical Field

[0002] A kiln or furnace is a furnace used to fire ceramics and sculptures or to fuse enamel to the surface of metal objects. It is usually made of bricks and stones, and can be made into various sizes according to needs. It can be operated by combustible gas, oil or electricity;

[0003] When a kiln is firing powder, a large amount of dust and other suspended particle impurities will be generated during the process of moving the fired powder out of the kiln, causing pollution to the production workshop and the surrounding environment. The existing treatment method is to remove and purify the generated suspended particles and collect the suspended particles. Although this method can solve the pollution of suspended particles to the environment to a certain extent, some impurities in the powder cannot be diffused into the air in time during dust removal. During the loading process, part of them will escape into the air again, and the other part will remain in the powder, affecting the quality of the powder. After the dust removal device has been removing dust for a long time, the dust removal device can only be moved to other places to clean the collected dust; therefore, a large number of other dust removal devices need to be prepared for replacement, which not only increases the production cost, but also affects the use of the kiln.

[0015] Compared with the prior art, the present invention provides an industrial kiln for dust-free collection of powder, which has the following beneficial effects:

[0016] 1. The industrial kiln for dust-free collection of powders drives the airflow above the collecting hopper through the bag dust removal system in the dust removal mechanism, so that the suspended polluted particles move with the airflow, wherein the air inside the collecting chamber is extracted by the negative pressure fan, so that negative pressure is generated inside the collecting chamber, and the negative pressure provides power for the bag dust removal system. Since the powder produced by the industrial kiln still has a certain temperature after being cooled for a period of time, after the powder enters the collecting hopper, a higher temperature of suspended particles is generated in the collecting hopper, and the air temperature inside the collecting hopper is increased, so that the suspended particles float out of the collecting hopper. At this time, the inside of the collecting hopper is in a high pressure state, and the air collecting chamber in the negative pressure state is cooperated, and the airflow above the collecting hopper is driven by the bag dust removal system, so that the high-pressure gas inside the collecting hopper can be discharged, and the suspended particles are isolated by the bag dust removal system, and will not escape into the external air with the high-pressure gas, causing pollution to the external air.

[0017] 2. The industrial kiln for dust-free collection of powder has a large amount of suspended particles remaining on the bag-type dust removal system, which reduces the working efficiency of the bag-type dust removal system. When the industrial kiln is working, the bag-type dust removal system is cleaned by an external cleaning system arranged on one side of the bag-type dust removal system, and the bag-type dust removal system is moved outward to the cleaning chamber, and the bag-type dust removal system is backblown and cleaned by a pulse backblowing component. During the cleaning process, the dust-proof plates on both sides of the cleaning chamber isolate the bag-type dust removal system being cleaned to prevent the suspended particles generated during cleaning from entering the external air and returning to the collecting hopper again, thereby blowing off the particles remaining on the bag-type dust removal system and collecting them by the ash collecting hopper at the bottom of the cleaning chamber. After the bag-type dust removal system is cleaned, the quality of the bag-type dust removal system can be checked in time to avoid damage to the bag-type dust removal system after long-term work and failure to replace it in time, which affects the quality of dust-free collection of powder.

[0018] 3. The industrial kiln for dust-free collection of powder is installed as a whole by the dust collector carrier plate in the bag dust removal system, and then installed between the air collecting chamber and the collecting hopper. When the powder enters the collecting hopper and generates suspended particles, the negative pressure fan draws out the air in the air collecting chamber, so that the inside of the air collecting chamber is in a negative pressure state. Then the air collecting chamber in the negative pressure state draws out the air inside the bag dust collector through the air collecting pipe, so that the inside of the bag dust collector is also in a negative pressure state, and then the air in the collecting hopper is drawn into the bag dust collector, and then the high pressure caused by the temperature rise and suspended particles in the collecting hopper is released, and at the same time, the suspended particles are prevented from escaping into the air.

[0019] 4. The industrial kiln for dust-free collection of powder uses the pulse air pump in the pulse back-blowing assembly to perform pulse blowing on the back-blowing connecting pipe, and then the back-blowing connecting pipe blows air to the air collecting pipe through the back-blowing interface, and then the bag dust collector is cleaned by pulse back-blowing. When the bag dust collector moves along the installation guide groove on the dust collector carrier plate to the inside of the cleaning chamber, the notch opened above the air collecting pipe above the bag dust collector is aligned with the back-blowing interface, so that the back-blowing interface passes through the notch, and then the back-blowing interface is aligned with the air collecting pipe. When pulse blowing is performed at the back-blowing interface, air is blown into the inside of the air collecting pipe, and due to the pulse blowing, a short period of high pressure is caused during the blowing. At this time, the setting of the notch can reduce the pressure of the pulse blowing to avoid damage to the bag dust collector caused by excessive pressure, and after the bag dust collection system completes the cleaning, the quality of the bag dust collection system can be checked in time to avoid damage to the bag dust collection system after long-term work and failure to replace it in time, which affects the quality of dust-free collection of powder.

[0046] In the above process, the bag dust collector 41 is installed as a whole through the dust collector carrier plate 42 in the bag dust removal system 4, and then installed between the air collecting chamber 6 and the collecting hopper 2. When the powder enters the collecting hopper 2 and generates suspended particles, the negative pressure fan 7 draws out the air in the air collecting chamber 6, so that the inside of the air collecting chamber 6 is in a negative pressure state. Then, the air collecting chamber 6 in the negative pressure state draws out the air inside the bag dust collector 41 through the air collecting pipe 43, so that the inside of the bag dust collector 41 is also in a negative pressure state, and then the air inside the collecting hopper 2 is drawn into the bag dust collector 41, and then the high pressure caused by the temperature rise and suspended particles inside the collecting hopper 2 is released, and at the same time, the suspended particles are prevented from escaping into the air.

[0047] After working for a long time, a large amount of suspended particles remain on the bag-type dust removal system 4, which reduces the working efficiency of the bag-type dust removal system 4. When the industrial kiln is working, the bag-type dust removal system 4 is cleaned by the external cleaning system 5 arranged on one side of the bag-type dust removal system 4, and the bag-type dust removal system 4 is moved outward to the cleaning chamber 51. Through the installation guide groove 61 arranged at the bottom of the air collecting chamber 6, the dust collector carrier plate 42 is cooperated to enable the bag-type dust collector 41 to be moved out from the dust removal chamber 9, and moved along the installation guide groove 61 to the cleaning chamber 51 for back-blowing cleaning; the pulse back-blowing component 53 back-blows the bag-type dust removal system 4, and the dust removal chamber 9 arranged between the air collecting chamber 6 and the collecting hopper 2 is placed on the bag-type dust removal system 4, and then the dust-proof plate 52 composed of the air collecting sealing plate 521 and the dust removal sealing plate 522 is used to back-blown the dust removal chamber 9 and the collecting hopper 2 when the powder enters the collecting hopper 2. The side of the air collecting chamber 6 is sealed; during the cleaning process, the dust-proof plates 52 located on both sides of the cleaning chamber 51 isolate the bag-type dust removal system 4 that is being cleaned, to prevent the suspended particles generated during the cleaning from entering the external air and returning to the collecting hopper 2 again, and then blow off the particles remaining on the bag-type dust removal system 4, and collect them by the ash collecting hopper 8 at the bottom of the cleaning chamber 51. The dust-proof plates 52 composed of the fixed grid plates 511 arranged on both sides of the cleaning chamber 51 cooperate with the air collecting sealing plates 521 and the dust removal sealing plates 522 to block the two sides of the cleaning chamber 51 when the bag-type dust collector 41 is back-blown for cleaning, wherein when the bag-type dust collector 41 moves into the cleaning chamber 51, the dust-proof plates 52 move to merge with the fixed grid plates 511, so that the fixed grid plates 511 are in an open state, thereby facilitating the bag-type dust collector 41 to enter the cleaning chamber 51 through the fixed grid plates 511;

[0048] The opening 512 opened on the side of the cleaning chamber 51 facilitates the movement of the dustproof plate 52. When the dustproof plate 52 moves to merge with the fixed grid plate 511, the dustproof plate 52 moves toward the opening 512, and one end of the dustproof plate 52 moves out of the opening 512. When a group of bag dust collectors 41 moves between the two groups of dustproof plates 52, the dustproof plate 52 moves into the cleaning chamber 51, and then the dustproof plate 52 cooperates with the fixed grid plate 511 to block the two sides of the cleaning chamber 51, and one side of the dustproof plate 52 blocks the opening 512, and then the dustproof plate 52 is fixed by the lock button 513 in cooperation with the lock port 523 opened on the side of the dustproof plate 52;

[0049] The pulse air pump 531 in the pulse back-blowing assembly 53 performs pulse blowing on the back-blowing connecting pipe 532, and then the back-blowing connecting pipe 532 blows air to the air collecting pipe 43 through the back-blowing interface 533, and then the bag dust collector 41 is subjected to pulse back-blowing cleaning. When the bag dust collector 41 moves along the installation guide groove 61 on the dust collector carrier plate 42 toward the inside of the cleaning chamber 51, the notch 431 above the air collecting pipe 43 above the bag dust collector 41 is aligned with the back-blowing interface 533, so that the back-blowing interface 533 passes through the notch 431, and then the back-blowing connecting pipe 532 is The port 533 is aligned with the air collecting pipe 43. When the back-blowing interface 533 performs pulse blowing, air is blown into the air collecting pipe 43. Due to the pulse blowing, a short period of high pressure will be caused during the blowing. At this time, the setting of the notch 431 can reduce the pressure of the pulse blowing to avoid damage to the bag-type dust collector 41 caused by excessive pressure. After the bag-type dust collection system 4 is cleaned, the quality of the bag-type dust collection system 4 can be checked in time to avoid damage to the bag-type dust collection system 4 after long-term operation and failure to replace it in time, which affects the quality of dust-free collection of powder.
