Description

Technical Field

[0001] This utility model belongs to the field of granulator technology, specifically relating to a dust collection device for a plastic granulator. Background Technology

[0002] Granulators are mechanical equipment that process powder, molten or wet materials into regular granules through physical or chemical action. They are widely used in chemical, fertilizer, plastics, pharmaceutical and other fields. They achieve material granulation through mechanical force or chemical reaction. Their types and functions are highly matched with industry needs and are key equipment for resource recycling and efficient production.

[0003] A review of announcement number CN205965402U reveals a water-based dust removal device for a granulator. This technology discloses "a dust collection box and a wet curtain paper. The wet curtain paper is located inside the dust collection box and divides the inner cavity of the dust collection box into a front cavity and a rear cavity. The front cavity is connected to the air outlet of the gas collection hood via a first air supply pipe, and the rear cavity is connected to the air inlet of the centrifugal blower via a second air supply pipe. The dust collection box is equipped with water spray nozzles positioned directly above the wet curtain paper, and a water outlet is located at the bottom of the dust collection box. This invention can separate dust from the gas before it enters the centrifugal blower, preventing dust from entering the centrifugal blower and ensuring its long-term normal operation. This, in turn, facilitates the long-term normal operation of the entire water-based dust removal device and guarantees a good dust removal effect."

[0004] Although this design can separate dust from the gas before it enters the centrifugal blower, preventing dust from entering the blower and ensuring its long-term normal operation, thus facilitating the long-term normal operation of the entire water dust removal device and ensuring good dust removal effect, dust may still be adsorbed inside the device during separation. Consequently, when the material is discharged, the dust will adhere to the surface of the material, affecting the dust removal effect.

[0005] To address the aforementioned problems, this application proposes a dust collection device for a plastic granulator. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a dust collection device for a plastic granulator. Through the operation of a fan, left filter plate, and B ventilation plate, dust from the granules is blown straight across the surface of the corrugated plate and carried by water flow to the mixing chamber. This prevents dust from affecting subsequent granulated raw materials, effectively reducing dust adsorption on the raw material surface and ensuring more stable dust collection. Furthermore, the dust and water mixture stored inside the mixing chamber will not be re-erected by the wind, providing sufficient stability and practicality for the dust collection process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust collection device for a plastic granulator, comprising a separation chamber, a feed inlet, and a left filter plate, and further comprising a fan installed inside the separation chamber, an A ventilation plate being provided on one side of the fan, a B ventilation plate being provided on the side of the A ventilation plate away from the fan, and a corrugated plate being installed on the inner surface of the separation chamber on the other side of the B ventilation plate, and a drip pipe being installed on the surface of the separation chamber above the corrugated plate, and the drip pipe also penetrating the separation chamber and connecting to a water tank mounted on the surface of the separation chamber.

The left filter plate is fixedly installed on the surface of the A ventilation plate, and the right filter plate is installed on the surface of the B ventilation plate.

[0009] As a preferred embodiment of the dust collection device for a plastic granulator according to this utility model, the surfaces of the A ventilation plate, the left filter plate, the right filter plate, and the B ventilation plate are all provided with through holes.

[0010] As a preferred embodiment of the dust collection device for a plastic granulator according to this utility model, the corrugated plate is installed at an incline on the inner surface of the separation chamber, and the surface of the corrugated plate has a corrugated structure.

[0011] As a preferred embodiment of the dust collection device for a plastic granulator according to this utility model, a mixing chamber is provided at the bottom of the corrugated plate, and the mixing chamber is connected to the space where the corrugated plate is located. An observation window is also provided on the surface of the separation chamber.

[0012] As a preferred embodiment of the dust collection device for a plastic granulator according to this utility model, a storage box is provided at the bottom of the right filter plate, and the storage box and the separation chamber are slidably connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the operation of the fan, left filter plate, and B ventilation plate can blow the dust in the particles straight onto the surface of the corrugated plate and carry the dust to the location of the mixing chamber through water flow, avoiding the dust from affecting the subsequent particle raw materials. It can effectively reduce the situation of dust adhering to the surface of the raw materials, making the subsequent dust collection work more stable. At the same time, the mixture of dust and water stored inside the mixing chamber will not be stirred up again by the wind, providing sufficient stability and practicality for the dust collection work.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figure 1 As shown:

[0023] A dust collection device for a plastic granulator includes a separation chamber 1.

[0024] In this implementation plan: The existing announcement number CN205965402U discloses a water dust removal device for a granulator. This technical means will not be described in detail here. For improvements to this prior art, please refer to the following disclosure. To solve the technical problems existing in this prior art, such as the "dust may be adsorbed inside the device during separation, and then adsorbed on the surface of the material when it is discharged, affecting the dust removal effect" disclosed in the background art above, this problem is obviously a real and difficult problem to solve. Therefore, to solve the above problems, a ventilation plate 7 and a corrugated plate 8 are added on the basis.

[0025] Furthermore:

[0026] like Figure 1 - Figure 4 As shown:

[0027] In conjunction with the above, it also includes a fan 3 installed inside the separation chamber 1, an A ventilation plate 4 on one side of the fan 3, a B ventilation plate 7 on the side of the A ventilation plate 4 away from the fan 3, and a corrugated plate 8 installed on the inner surface of the separation chamber 1 on the other side of the B ventilation plate 7. A drip pipe 9 is installed on the surface of the separation chamber 1 above the corrugated plate 8, and the drip pipe 9 also penetrates the separation chamber 1 and is connected to the water tank 10 mounted on the surface of the separation chamber 1.

[0028] In this implementation scheme: the fan 3, ventilation plate A 4 and ventilation plate B 7 can blow the dust to the other side of ventilation plate B 7 during dust removal, thereby adsorbing the dust onto the water film flowing on the surface of the corrugated plate 8, preventing the dust from being scattered inside the device and carried out by particles.

[0029] Furthermore:

[0030] In an optional embodiment, a feed inlet 2 is fixedly installed on the surface of the separation chamber 1, and an A ventilation plate 4 and a B ventilation plate 7 are also installed on both sides of the inner surface of the separation chamber 1. A left filter plate 5 is fixedly installed on the surface of the A ventilation plate 4, and a right filter plate 6 is installed on the surface of the B ventilation plate 7.

[0031] In this embodiment: the feed inlet 2 installed on the surface of the separation chamber 1 can stably supply materials, while the A ventilation plate 4 and the left filter plate 5 can also stably separate materials, so that the wind blowing by the A ventilation plate 4 and the B ventilation plate 7 can carry away the dust.

[0032] Furthermore:

[0033] In an optional embodiment, through holes are provided on the surfaces of ventilation plate 4 (A), left filter plate 5, right filter plate 6, and ventilation plate 7 (B).

[0034] In this embodiment: the through holes on the surfaces of the left filter plate 5 and the right filter plate 6 allow the dust in the particles to be filtered when passing through their surfaces, while the through holes on the surfaces of the A ventilation plate 4 and the B ventilation plate 7 allow the wind force generated by the fan 3 to blow the dust to the location of the wave plate 8.

[0035] Furthermore:

[0036] In an optional embodiment, the corrugated plate 8 is installed at an angle on the inner surface of the separation chamber 1, and the surface of the corrugated plate 8 has a corrugated structure.

[0037] In this embodiment, the inclined wave plate 8 can create a stable flow state between the water flow and the wave plate 8, and the wave-shaped wave plate 8 can increase the distance that the water flow passes over its surface, providing stable conditions for dust adsorption.

[0038] Furthermore:

[0039] In an optional embodiment, a mixing chamber 11 is provided at the bottom of the wave plate 8, and the mixing chamber 11 is connected to the space where the wave plate 8 is located. An observation window 13 is also provided on the surface of the separation chamber 1.

[0040] In this embodiment, the mixing chamber 11 provided at the bottom of the wave plate 8 allows water mixed with dust on the surface of the wave plate 8 to flow smoothly into the interior of the mixing chamber 11, thereby ensuring that the surface of the wave plate 8 remains clean and providing effective conditions for subsequent dust adsorption.

[0041] Furthermore:

[0042] In an optional embodiment, a storage box 12 is provided at the bottom of the right filter plate 6, and the storage box 12 and the separation chamber 1 are slidably connected.

[0043] In this embodiment, the storage box 12 at the bottom of the right filter plate 6 can store plastic particles when the dust collection work is completed, which facilitates material storage and allows subsequent processing steps to proceed stably.

[0044] The working principle and usage process of this utility model are as follows: When it is necessary to perform dust collection on plastic granules, the material can be injected into the separation chamber 1 through the feed inlet 2. Subsequently, the material will gradually roll down along the left filter plate 5 and the right filter plate 6. At this time, the fan 3 will blow air through the ventilation plate A 4, and the blown-down dust will cross the ventilation plate B 7 and reach the surface of the corrugated plate 8. The water tank 10 will continuously apply water to the surface of the corrugated plate 8 through the drip pipe 9, forming a water film on the surface of the corrugated plate 8. When the dust comes into contact with the surface of the corrugated plate 8, The water flow will carry the dust droplets into the interior of the mixing chamber 11, and the plastic particles with the dust removed will fall along the left filter plates 5 and the right filter plates 6 into the storage box 12 for storage. After the dust collection is completed, the wastewater mixed with dust can be discharged through the drain on one side of the mixing chamber 11, and the storage box 12 can be pulled out from the bottom of the separation chamber 1 to complete the removal of particulate dust. The observation window 13 on one side of the separation chamber 1 can also be used to observe the accumulation of dust inside the mixing chamber 11, which is convenient for subsequent cleaning work.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model 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 make equivalent substitutions for some of the technical features.
