Description

Technical Field

[0001] The utility model relates to the technical field of dust collection, and more specifically, the utility model relates to a pigment dust collection device. Background Art

[0002] The full name of the color masterbatch is color masterbatch, also called colorant, which is a new type of special coloring agent for polymer materials, also known as pigment preparation. The color masterbatch is mainly used in plastics. The color masterbatch consists of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly loading an ultra-large amount of pigment in the resin, and can be called pigment concentrate. When the color masterbatch pigment is transported and used, it is easy to generate floating color masterbatch pigment dust, and it is necessary to collect the floating color masterbatch pigment dust. Therefore, a dust collection device is proposed for collecting color masterbatch pigment dust.

[0003] Most of the existing pigment dust collection devices adopt the form of suction, sucking air and dust in the air into the device, and filtering the dust through a filter screen plate. However, after a long time of filtration, the dust accumulates on one side of the filter plate, so it is necessary to manually pause the operation of the device and pull out the filter plate for cleaning, which is rather troublesome and affects the dust collection efficiency.

[0010] In a preferred embodiment, an inclined scraper is fixedly provided at the output end of the cylinder. The upper end of the inclined scraper is fixedly connected to the lower end of the limit slide rod, and the inclined scraper is in close contact with the dust filter plate.

[0011] In a preferred embodiment, the automatic closing device includes a material discharge port. The material discharge port is opened inside the connecting plate. An active connecting rod penetrates through the inner wall of the outer shell. Both ends of the active connecting rod are movably connected to both sides of the inner wall of the outer shell. A collection box is movably provided in the cavity at the lower end of the material discharge port.

[0012] In a preferred embodiment, a closing plate is fixedly provided on the outer surface of the active connecting rod. The closing plate is located inside the outer shell. Stirring rods are fixedly provided on both sides of the closing plate respectively.

[0013] In a preferred embodiment, arc-shaped sliding grooves are opened on both sides of the outer shell. The stirring rods penetrate through the inner sides of the arc-shaped sliding grooves.

[0016] The technical effects and advantages of the present utility model:

[0017] 1. By providing a scraping and collecting device, the present utility model is beneficial to scrape and discharge the dust accumulated on one side of the dust filter plate, avoiding the accumulation of dust on one side of the dust filter plate and affecting the collection efficiency. It can automatically discharge dust to achieve the collection effect. Through the cyclic operation of the cylinder, the inclined scraper is driven to scrape the dust filter plate up and down. Since the inclined scraper is inclined, when the dust at the scraping position detaches from the dust filter plate, it blocks the air flow, avoiding the re-suspension of dust caused by the air flow. When the inclined scraper moves upward, the dust at the upper scraping position can be detached from the dust filter plate. Affected by the air flow, the dust at the upper end of the inclined scraper is lifted, so as to perform secondary filtration. When the inclined scraper moves downward to the material discharge port, the dust is pushed out and falls into the collection box, thus achieving the collection effect;

[0018] 2. The utility model is provided with an automatic closing device, which is conducive to discharging dust when the scratch collection device is pressed down, and automatically closes when the scratch collection device rises, thereby preventing wind from passing through and causing the dust in the collection box to be raised again. The closing plate is pressed down by the oblique scraper to expand the closing plate, thereby pushing the dust to the discharge port and falling into the collection box. Because the toggle rod is pushed upward by the force of the coil spring, when the oblique scraper moves upward, the closing plate can be reset to close the discharge port and prevent wind from passing through.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the dust collection field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 , 2As shown in FIGS. 2 and 3, the present utility model provides a pigment dust collection device, including a housing 1. A connecting plate 13 is fixedly provided inside the housing 1. Limiting grooves 14 are opened on both sides of the inner wall of the housing 1. A dust filter plate 10 is movably provided inside the limiting grooves 14. An air inlet cylinder 4 is fixedly provided on one side of the housing 1. A motor fixing bracket 12 is fixedly provided inside the air inlet cylinder 4. An exhaust fan 11 is fixedly provided inside the motor fixing bracket 12. An exhaust window 5 is fixedly provided on the other side of the housing 1.

[0027] In order to automatically discharge dust to achieve the collection effect, a scraping and collecting device 2 capable of scraping the dust filter plate 10 is provided at the upper end of the housing 1, which is used to scrape and discharge the dust accumulated on one side of the dust filter plate 10.

[0028] As Figure 4 shown, the scraping and collecting device 2 includes a cylinder 21. The cylinder 21 is fixedly provided at the upper end of the housing 1. The output end of the cylinder 21 penetrates through the upper end of the housing 1. Limiting sliding rods 22 are movably provided in two grooves at the upper end of the housing 1. An inclined scraper 23 is fixedly provided at the output end of the cylinder 21. The upper end of the inclined scraper 23 is fixedly connected to the lower end of the limiting sliding rod 22. The inclined scraper 23 is in close contact with the dust filter plate 10. Through the cyclic operation of the cylinder 21, the inclined scraper 23 is driven to scrape the dust filter plate 10 up and down. Because the inclined scraper 23 is inclined, when the dust at the scraping position detaches from the dust filter plate 10, the air flow is blocked to avoid the dust being raised again due to the air flow. When the inclined scraper 23 moves upward, the dust at the upper scraping position can detach the dust on the dust filter plate 10. Affected by the air flow, the dust at the upper end of the inclined scraper 23 is raised, so as to perform secondary filtration. When the inclined scraper 23 moves downward to the feeding port 35, the dust is pushed out and falls into the collection box 9, thus achieving the collection effect.

[0029] Furthermore, in order to avoid the dust in the collection box from being raised again, an automatic closing device 3 capable of automatically closing is provided inside the housing 1, which is used to discharge the dust when the scraping and collecting device 2 presses down and automatically closes when the scraping and collecting device 2 rises.

[0030] As Figure 5As shown in the figure, the automatic closing device 3 includes a blanking port 35. The blanking port 35 is opened on the inner side of the connecting plate 13. An active connecting rod 31 penetrates through the inner wall of the outer shell 1. Both ends of the active connecting rod 31 are movably connected to both sides of the inner wall of the outer shell 1. A collection box 9 is movably arranged in the lower cavity of the blanking port 35. A closing plate 32 is fixedly arranged on the outer surface of the active connecting rod 31. The closing plate 32 is located inside the outer shell 1. Stirring rods 33 are fixedly arranged on both sides of the closing plate 32. Arc-shaped sliding grooves 34 are opened on both sides of the outer shell 1. The stirring rods 33 penetrate through the inner side of the arc-shaped sliding grooves 34. Spring fixing blocks 6 are fixedly arranged on both sides of the outer shell 1. A spring 7 is fixedly arranged on the outer surface of the spring fixing block 6. The movable end of the spring 7 is located below the stirring rod 33. A limiting cover 8 is fixedly arranged on one side of the spring fixing block 6. By pressing down the closing plate 32 with the inclined scraper 23, the closing plate 32 is unfolded, so as to push the dust to the blanking port 35 and fall into the collection box 9. Because the stirring rod 33 is subjected to the force of the spring 7 upwards, when the inclined scraper 23 moves upwards, the closing plate 32 can be reset, and the closing plate 32 closes the blanking port 35 to prevent the air flow from passing through.

[0031] The working principle is as follows: When the present utility model is in use, the dust and air are drawn into the present utility model through the exhaust fan 11 in the air inlet cylinder 4, and are filtered by the dust filter plate 10. The filtered air is discharged through the exhaust window 5. When the present utility model is working, the scraping and collecting device 2 is used to scrape and discharge the dust on one side of the dust filter plate 10, so as to avoid dust accumulation. With the automatic closing effect of the automatic closing device 3, the air flow is prevented from passing through the blanking port 35 to raise the dust in the collection box 9. Overall, the trouble of frequent manual cleaning of the dust filter plate 10 is reduced, and the working efficiency of the present utility model is improved.

[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
