Description

Technical Field

[0001] The present application relates to the technical field of wood processing equipment, and particularly to a dust suction device for wooden hangers. Background Art

[0002] After the production of the flat wooden hanger blank is completed, processes such as notch sanding, sanding of both side planes, bottom surface sanding, and back surface sanding are still required. A large amount of dust will be generated during these processes. To protect the health of workers and prevent the risk of dust explosion, enterprises usually set up negative pressure dust suction devices for these processes. Existing negative pressure devices often use bag filters to separate dust particles from air. Since dust will adhere to the bags, it is necessary to blow the dust adhering to the bags through a back-blowing pipe. For example, a Chinese patent with the application number 201910856668.9 discloses a bag filter, which includes a filtering component, and a dust cleaning structure is arranged on the filtering component. The dust cleaning structure includes an annular elastic member sleeved outside the filtering component, and a connecting member is arranged on the annular elastic member. The connecting member is connected to a cam mechanism connected to the bag filter, and the connecting member is pushed by a cam in the cam mechanism to deform the annular elastic member to move away from the filtering component. When blowing dust, the dust collector drives the cover plate to move downward through a second electric telescopic rod to block the orifice of the flower plate, so that the airflow blown out by the blowing pipe flows out from the bag. However, this device has the following problems: there are multiple bags in the bag filter, and multiple electric telescopic rods are required. When blowing, the electric telescopic rods need to bear the impact of the airflow, resulting in easy damage to the electric telescopic rods. Moreover, the electric telescopic rods are located inside the bag filter, making maintenance difficult. Therefore, a dust suction device for wooden hangers is needed, in which the first blowing pipe extends from the side into the connecting pipe, and a movable baffle is arranged in the connecting pipe. When blowing dust, the movable baffle can automatically close the upper part of the connecting pipe under the action of the airflow, with a simple structure and high reliability. Summary of the Utility Model

[0003] To solve the above problems, the present application proposes a dust suction device for wooden hangers, in which the first blowing pipe extends from the side into the connecting pipe, and a movable baffle is arranged in the connecting pipe. When blowing dust, the movable baffle can automatically close the upper part of the connecting pipe under the action of the airflow, with a simple structure and high reliability.

[0004] The present application is achieved through the following technical solutions:

[0005] This application provides a dust suction device for wooden hangers, comprising: a housing, a partition board, a first air blowing pipe, and a cloth bag. The partition board is horizontally installed in the middle of the housing. The partition board is provided with a plurality of through holes, and communicating pipes are arranged on the through holes. A cage-shaped framework is arranged below the communicating pipes. The cloth bag covers the outer periphery of the cage-shaped framework, and the mouth of the cloth bag is connected to the lower part of the communicating pipe through a clamp. The first air blowing pipe extends from the side of the upper part of the communicating pipe to the middle of the communicating pipe, bends downward and extends to the middle of the cage-shaped framework. Air holes are arranged at the lower end of the first air blowing pipe. A second air blowing pipe is arranged on the upper part of the first air blowing pipe. The lower end of the second air blowing pipe is communicated with the first air blowing pipe, and a movable baffle is installed on the upper part of the second air blowing pipe. The outer diameter of the movable baffle is smaller than the inner diameter of the upper opening of the communicating pipe.

[0006] Further, a guiding rod is arranged at the upper end of the second air blowing pipe. The central axes of the second air blowing pipe, the guiding rod, and the communicating pipe coincide. A plurality of air holes are arranged on the side wall of the upper part of the second air blowing pipe.

[0007] Further, the middle part of the movable baffle is sleeved on the upper part of the second air blowing pipe, and the movable baffle is slidably connected with the guiding rod. The upper part of the communicating pipe is in a flared shape.

[0008] Further, the communicating pipes are distributed in a rectangular array on the partition board. The first air blowing pipes on the communicating pipes in the same row are mutually connected in parallel through air supply branch pipes. An air supply main pipe is arranged outside the housing. The air supply branch pipes are connected to the air supply main pipe through valves.

[0009] Further, an air inlet pipe is arranged at the lower part of the housing. The air inlet pipe passes through the housing, and air holes are arranged in the middle of the air inlet pipe. Both ends of the air inlet pipe are connected to the air collecting hood on the wooden hanger processing station, and an ash discharge valve is arranged at the bottom of the housing.

[0010] Further, a negative pressure fan is further included. The negative pressure fan is communicated with the upper part of the housing through a pipeline.

[0011] The beneficial effects of this application: The air containing dust is sucked from the air collecting hood on the wooden hanger processing station into the housing through the negative pressure fan. After the airflow is filtered by the cloth bag, when blowing ash, the movable baffle is blown by the second air blowing pipe to move upward and block the communicating pipe, so that all the blowing ash airflow is discharged from the lower part of the communicating pipe, improving the efficiency of blowing ash. The movement of the movable baffle does not require other power devices, with a simple structure and high reliability. Description of the Drawings

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the said features.

[0019] As Figures 1 to 3As shown in the figure, an embodiment of the present utility model provides a dust suction device for wooden hangers, which includes: a housing 1, a partition 2, a first air blowing pipe 3, and a cloth bag 5. The partition 2 is horizontally installed in the middle of the housing 1. The partition 2 is provided with a plurality of through holes, and a connecting pipe 6 is provided on the through holes. A cage-shaped frame 7 is provided below the connecting pipe 6. The cloth bag 5 covers the outer periphery of the cage-shaped frame 7, and the mouth of the cloth bag 5 is connected to the lower part of the connecting pipe 6 through a clamp; the first air blowing pipe 3 extends from the side of the upper part of the connecting pipe 6 to the middle of the connecting pipe 6, the first air blowing pipe 3 extends downward and bends to the middle of the cage-shaped frame 7, and air holes are provided at the lower end of the first air blowing pipe 3. A second air blowing pipe 8 is provided at the upper part of the first air blowing pipe 3. The lower end of the second air blowing pipe 8 is communicated with the first air blowing pipe 3, and a movable baffle 9 is installed at the upper part of the second air blowing pipe 8. The outer diameter of the movable baffle 9 is smaller than the inner diameter of the upper opening of the connecting pipe 6.

[0020] After the negative pressure fan 4 operates, a negative pressure is formed in the housing 1. The air containing dust is sucked from the air collecting hood at the wooden hanger processing station and enters the lower part of the housing 1 through the air inlet pipe 13. Under the action of air pressure, the air flow passes through the cloth bag 5 and then enters the upper part of the housing 1. Fibers on the cloth bag are intertwined to form a plurality of fine holes, blocking the dust in the air flow, so that the dust remains on the cloth bag. When the dust accumulates to a certain extent, it will hinder the air flow from passing through the cloth bag 5 and increase the resistance. To avoid the above situation, it is necessary to clean the dust regularly. The air supply main pipe 12 is connected to a high-pressure air source. When cleaning the dust, the valve between the air supply branch pipe 11 and the air supply main pipe 12 is opened. Compressed air enters the first air blowing pipe 3 from the air supply branch pipe 11 and is blown into the cloth bag 5 through the first air blowing pipe 3. At the same time, a part of the air flow blows upward through the second air blowing pipe 8. Under the action of the air flow, the movable baffle 9 quickly moves upward, making the through diameter of the upper part of the connecting pipe 6 smaller and smaller, and pressing the movable baffle 9 on the connecting pipe 6 under the action of air pressure, thereby blocking the upper part of the connecting pipe 6, so that the air flow can only be discharged from the lower part of the connecting pipe 6, making the air flow pass through the cloth bag 5 from the inside to the outside, blowing off the dust attached to the cloth bag, and ensuring the filtration efficiency of the cloth bag 5. After stopping blowing the dust, after closing the valve between the air supply branch pipe 11 and the air supply main pipe 12, the air pressure in the connecting pipe 6 drops, and the movable baffle 9 drops under the action of gravity, thereby reopening the upper part of the connecting pipe 6 to facilitate the air flow to pass through. When filtering the air flow normally, due to the low flow rate and the long distance between the movable baffle 9 and the upper part of the connecting pipe 6, the movable baffle 9 partially blocks the connecting pipe 6. The movable baffle 9 automatically blocks the connecting pipe 6 through the air flow during dust blowing, without relying on devices such as push rods, with a simple structure and high reliability.

[0021] In a preferred embodiment, as Figure 2As shown in the figure, a guide rod 10 is provided at the upper end of the second air blowing pipe 8. The central axes of the second air blowing pipe 8, the guide rod 10, and the connecting pipe 6 coincide. A plurality of air holes are provided on the upper side wall of the upper part of the second air blowing pipe 8. The guide rod 10 can guide the lifting of the movable baffle 9, facilitating the effective blocking of the upper part of the connecting pipe 6 by the movable baffle 9. The compressed air blown out from the second air blowing pipe 8 can push the movable baffle 9 upward. There is still a certain distance between the movable baffle 9 and the upper part of the connecting pipe 6. However, after the movable baffle 9 moves upward, the diameter of the upper part of the connecting pipe 6 decreases, and there will be a pressure difference between the upper and lower ends of the movable baffle 9. At the same time, the movable baffle 9 also has a certain inertia. Under the action of these factors, the movable baffle 9 will continue to move upward along the guide rod 10 to completely seal the upper part of the connecting pipe 6, enabling the blowing ash air flow to flow out smoothly through the cloth bag 5 and improving the efficiency of blowing ash.

[0022] Specifically, as Figure 2 shown, the middle part of the movable baffle 9 is sleeved on the upper part of the second air blowing pipe 8, and the movable baffle 9 is slidably connected to the guide rod 10. The upper part of the connecting pipe 6 is in a flared shape. During normal filtration, the movable baffle 9 is sleeved on the upper part of the second air blowing pipe 8 under the action of gravity, and the air flow passes through the gap between the movable baffle 9 and the connecting pipe 6 to flow through the connecting pipe 6, ensuring the normal filtration of the connecting pipe 6.

[0023] In a specific embodiment, as Figure 1 shown, the connecting pipes 6 are distributed in a rectangular array on the partition plate 2. The first air blowing pipes 3 on the connecting pipes 6 in the same row are connected in parallel with each other through the air supply branch pipes 11. An air supply main pipe 12 is provided outside the housing 1, and the air supply branch pipes 11 are connected to the air supply main pipe 12 through valves. Each time, the cloth bags on the connecting pipes 6 in one row can be blown with ash simultaneously, improving the speed of blowing ash. And when blowing ash, the movable baffle 9 blocks the connecting pipe 6, and there is no need to stop the machine for blowing ash, and the device can operate continuously.

[0024] In a specific embodiment, an air inlet pipe 13 is provided at the lower part of the housing 1. The air inlet pipe 13 passes through the housing 1, and air holes are provided in the middle of the air inlet pipe 13. Both ends of the air inlet pipe 13 are connected to the air collecting hood on the wooden hanger processing station. And a dust discharging valve 14 is provided at the bottom of the housing 1. After a negative pressure is formed by the negative pressure fan 4, the air containing dust is sucked away from the wooden hanger processing station through the air inlet pipe 13, avoiding dust from harming the health of workers and reducing the risk of dust explosion.

[0025] Preferably, a negative pressure fan 4 is further included. The negative pressure fan 4 is connected to the upper part of the housing 1 through a pipeline. After a negative pressure is formed by the negative pressure fan 4, the air containing dust is sucked away from the wooden hanger processing station through the air inlet pipe 13, avoiding dust from harming the health of workers and reducing the risk of dust explosion.

[0026] Of course, this application may also have many other implementation manners. Based on this implementation manner, all other implementation manners obtained by those of ordinary skill in the art without any creative work fall within the scope protected by this application.
