Description

Dust recovery device for pearlescent powder production Technical Field

[0001] This invention relates to the technical field of dust recovery devices for pearlescent powder production, and particularly to the technical field of dust recovery devices for pearlescent powder production. Background Technology

[0002] Pearlescent pigments are composed of mica coated with thin layers of several metal oxides. Changing the layers of these metal oxides produces different pearlescent effects. Compared to other pigments, pearlescent pigments possess an unparalleled, soft, pearly luster. Since mica needs to be pulverized during use, a large amount of dust is generated. This dust not only pollutes the production workshop environment but also wastes raw materials. Therefore, it is necessary to recycle the dust in the production workshop.

[0003] However, existing workshops often use vacuum cleaners for localized dust removal, resulting in incomplete dust absorption inside the workshop and low work efficiency. In addition, some dust adheres to the inner wall of the dust collection cylinder, making it difficult to meet the dust collection needs of the production workshop.

[0004] Application No. 202020873982.6 proposes a dust recovery device suitable for pearlescent pigment production. This device, through the arrangement of a dust collection hood, fan, housing, filter screen, recovery bin, and discharge port, draws dust from pearlescent pigment production into the housing under the action of the fan. After being filtered by the filter screen, the dust falls into the recovery bin, and the residue on the filter screen can be discharged through the discharge port. This avoids the pollution of the production workshop environment caused by a large amount of dust generated during the pearlescent pigment production process. Furthermore, the device, through the arrangement of a motor, rotating rod, first cleaning brush, support arm, and second cleaning brush, uses the motor to clean the dust on the inner surface of the housing and the surface of the filter screen, respectively, preventing dust from adhering to the inner wall and causing incomplete recovery, thus improving dust recovery efficiency and reducing resource waste.

[0005] Although 202020873982.6 possesses the aforementioned advantages, it still has the following shortcomings;

[0006] 1. Some of the pearlescent pigment dust in the workshop is in the air and some falls on the ground. The pearlescent pigment dust in the air can be recycled and reused, but the pearlescent pigment dust that falls on the ground will mix with the dust on the ground and cannot be used directly. The above-mentioned device only has one dust suction hood. If only the pearlescent pigment dust in the air is recycled, the dust on the ground will still be stirred up by employees walking around and pollute the workshop. If both air and ground dust are absorbed, then the pearlescent pigment mixed with a large amount of dust on the ground is not suitable for direct recycling and use.

[0007] 2. When the above device recovers pearlescent pigment dust, it will also suck up some large pearlescent pigment particles. The large pearlescent pigment particles will accumulate on the filter screen and be discharged from the outlet after a certain amount is collected. The large pearlescent pigment particles need to be crushed again to become pearlescent pigment dust, which is a complicated process.

[0008] 3. The above-mentioned device cleans the dust on the inner surface of the housing and the surface of the filter screen by the first cleaning brush and the second cleaning brush respectively. However, the brushes will inevitably wear down over time, and the worn-out short bristles can easily fall into the recycling bin after passing through the filter screen, contaminating the recycled pearlescent pigment dust.

[0009] To solve the above problems, it is necessary to propose a dust recovery device for pearlescent powder production. Summary of the Invention

[0010] The purpose of this invention is to solve the problems in the prior art and propose a dust recovery device for pearlescent powder production. This device can classify and recover dust from the air and the ground, ensuring a clean workshop environment while enabling the direct recovery and reuse of pearlescent pigment dust in the air. It can also separately process pearlescent pigment mixed with a large amount of dust on the ground, and can directly crush large particles of the recovered pearlescent pigment, reducing subsequent handling processes. Furthermore, the vibration prevents pearlescent pigment from adhering to the inner wall of the recovery channel, avoiding contamination of the pearlescent pigment by lint from the brushes, and helping to maintain the purity of the pearlescent pigment.

[0011] To achieve the above objectives, this invention proposes a dust collection device for pearlescent powder production, comprising a bottom support, casters, a lower dust collection mechanism, and an upper dust collection mechanism.

[0012] Preferably, the lower dust collection mechanism includes a housing, a left chamber, a right chamber, a second dust collection hood, a second fan, a second air inlet pipe, a second air outlet pipe, and a dust collection box. The housing is located in the middle of the bottom support. The left and right ends of the housing are respectively provided with a left chamber and a right chamber.

[0017] The beneficial effects of this invention are as follows: This invention has a simple structure and reasonable design, enabling the classification and recycling of dust from the air and the ground. While ensuring a clean workshop environment, it allows for the direct recycling and reuse of pearlescent pigment dust in the air, and separates the pearlescent pigment mixed with a large amount of dust on the ground. It can directly crush the large particles of the recycled pearlescent pigment, reducing subsequent handling steps. Furthermore, vibration prevents the pearlescent pigment from adhering to the inner wall of the recycling channel, avoiding contamination of the pearlescent pigment by lint from the brushes, thus maintaining the purity of the pearlescent pigment. By setting an inner cylinder and its matching crushing blades, the large pearlescent pigment particles accumulated in the inner cylinder can be directly crushed, eliminating the need to transport them to other crushing devices, thus improving efficiency. A pressure sensor can detect the degree of accumulation of large pearlescent pigment particles in the inner cylinder. A vibration device drives the inner cylinder to vibrate, preventing the pearlescent pigment dust from adhering to the inner wall of the inner cylinder. The shaken-down pearlescent pigment dust falls through the sieve holes into the dust collection drawer.

[0027] The pressure sensor 33 and the vibration device 330 are both fixed to the inner wall of the limiting blind hole 311.

[0028] Working process of this invention:

[0029] In the operation of the dust recovery device for pearlescent pigment production of the present invention, when the pearlescent pigment production mechanism is running, the lower dust collection mechanism 2 operates, the second fan 23 starts, and the second dust collection hood 22 sucks up the mixture of pearlescent pigment dust and ash on the ground. The upper dust collection mechanism 3 operates, the first fan 36 starts, and the first dust collection hood 363 sucks up the pearlescent pigment dust that has escaped from the pearlescent pigment production mechanism in the air. The motor 351 runs slowly, using the crushing blades 353 as scrapers, so that the pearlescent pigment dust in the inner cylinder 34 flows smoothly into the dust collection drawer 32 through the sieve holes 342, avoiding a large accumulation of pearlescent pigment dust at the bottom of the inner cylinder 34. When the pressure sensor 33 detects that the inner cylinder 34 is in operation, the device recovers the dust. After large pearlescent pigment particles accumulate to a certain extent inside the inner cylinder 34, the motor 351 operates at high speed, and the pulverizing blades 353 rotate to pulverize the large pearlescent pigment particles. The pulverized pearlescent pigment falls into the dust collection drawer 32 through the sieve holes 342. When it is necessary to remove the pearlescent pigment dust adhering to the inner wall of the inner cylinder 34, the vibration device 330 drives the inner cylinder 34 to vibrate, making it difficult for the pearlescent pigment dust to adhere to the inner wall of the inner cylinder 34. The pearlescent pigment dust that is shaken down falls into the dust collection drawer 32 through the sieve holes 342. If there is some stubborn pearlescent pigment dust, it can be accumulated for a period of time, and then the lifting cover 35 can be raised to remove the inner cylinder 34 for thorough cleaning.

[0030] This invention features a simple structure and reasonable design, enabling the classification and recycling of dust from the air and ground. While ensuring a clean workshop environment, it allows for the direct recycling of pearlescent pigment dust from the air, and separates the pearlescent pigment mixed with a large amount of dust on the ground. It can directly crush large particles of the recycled pearlescent pigment, reducing subsequent handling steps. Furthermore, vibration prevents the pearlescent pigment from adhering to the inner wall of the recycling channel, avoiding contamination of the pearlescent pigment by lint from the brushes, thus maintaining the purity of the pearlescent pigment. The inner cylinder 3... 4 and its matching crushing blades 353 can directly crush the large pearlescent pigment particles accumulated in the inner cylinder 34 without having to transport them to other crushing devices, thus improving efficiency; by setting a pressure sensor 33, the degree of accumulation of large pearlescent pigment particles in the inner cylinder 34 can be detected; by setting a vibration device 330, the vibration device 330 drives the inner cylinder 34 to vibrate, so that the pearlescent pigment dust is not easy to adhere to the inner wall of the inner cylinder 34, and the pearlescent pigment dust that is shaken down falls into the dust collection drawer 32 through the sieve holes 342.
