Description

Technical Field

[0001] This utility model relates to the field of dustproof feeding technology, specifically a dustproof feeding station. Background Technology

[0002] In all stages of industrial production, the feeding of materials is a fundamental yet crucial operation. This is especially true in many industries such as chemicals, food, pharmaceuticals, and building materials, where the production process often involves feeding powders, granules, and other materials.

[0003] For example, an existing patent (publication number: CN218909104U) discloses a dust-free feeding station, including a feeding hopper, a discharge hopper at the bottom of the feeding hopper, a material hopper at the top of the feeding hopper, and the lower end of the material hopper extending into the feeding hopper. A bracket is fixed on the top wall of the feeding hopper, and a dustproof cover is hinged to the bracket. The bottom wall of the dustproof cover has an adapter groove, and the specifications of the adapter groove correspond to the specifications of the material hopper. Multiple inner grooves are opened circumferentially on the side wall of the material hopper. Multiple air blowing holes are opened on the inner wall of the material hopper, and the air blowing holes are connected to the corresponding inner grooves. A bag breaking component is provided on the material hopper, and a sealing component is provided inside the feeding hopper.

[0004] However, the above-mentioned dust-free feeding station design still has some drawbacks in actual use: The above device places the feeding bag in the hopper and opens it to avoid dust being stirred up when personnel pour it in from the outside. Then, the blower blows air through the air holes to reduce the dust adhering to the material bag. However, during the feeding process, the dust raised can easily clog the air holes. When the ambient humidity is high, the dust particles are more sticky and clogged in the air holes, making it difficult for the blower to blow them out. This makes it difficult for the blower to blow air into the hopper, which is not conducive to reducing the dust on the material bag. When personnel need to remove the material bag, they are still easily affected by the dust.

[0005] To address these issues, we designed a dust-proof feeding station. Utility Model Content

[0006] The purpose of this utility model is to provide a dustproof feeding station to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a dustproof feeding station, including a feeding bin and a storage bin set inside the feeding bin. The storage bin has a ventilation opening inside and a slot on the storage bin. A drive motor and an internal gear ring are installed in the slot. A gear is meshed on the internal gear ring. The drive end of the drive motor is connected to the bottom surface of the gear. A connecting shaft is connected to the top wall of the gear. A cleaning brush head is installed on the connecting shaft. One end of the cleaning brush head abuts against the inner wall of the slot.

[0008] Furthermore, a hollow cylinder is sleeved on the connecting shaft, and the cleaning brush head is disposed on the hollow cylinder. The cleaning brush head is conical in shape, and the tip of the cone faces away from the end of the connecting shaft.

[0009] Furthermore, a connecting ring is welded to the inner wall of the feeding bin, and the outer wall of the feeding bin is connected to the inner wall of the connecting ring.

[0010] Furthermore, an arc-shaped groove is formed on the inner bottom wall of the empty slot, and an arc-shaped block is slidably connected in the arc-shaped groove. The top surface of the arc-shaped block is connected to the bottom surface of the drive motor.

[0011] Furthermore, a column is connected to the inner bottom wall of the slot, and the other end of the column is connected to the bottom wall of the inner toothed ring. There are three columns, which are arranged around the bottom wall of the inner toothed ring.

[0012] Furthermore, a blower is installed outside the feeding hopper, and a connecting pipe is installed on the blower. The connecting pipe extends through the outer wall of the feeding hopper into the empty trough, and a blower head is connected to the end of the connecting pipe away from the blower.

[0013] Furthermore, the outer wall of the feeding hopper is connected to a support frame, the support frame is placed on the ground, the outer wall of the support frame is connected to a placement plate, and the blower is mounted on the placement plate by bolts.

[0014] Furthermore, a cover plate is provided at the top of the feeding hopper.

[0015] The beneficial effects of this utility model are: when the drive motor is started, the gear rotates and the gear will rotate in the slot. The cleaning brush head on the connecting shaft will rotate with the gear and make a circular motion in the slot. One end of the cleaning brush head abuts against the inner wall of the slot. During the rotation, it will insert into the ventilation port to clear the ventilation port, reduce the clogging of the ventilation port, and improve the efficiency of the blower.

[0016] The beneficial effects of this utility model are as follows: the cleaning brush head is conical in shape. When the cleaning brush head cleans the vent, its tip will first enter the vent. Then, as the cleaning brush head moves further in, the larger diameter end of the cleaning brush head will also enter the vent. The outer wall of the larger diameter end of the cleaning brush head abuts against the inner wall of the vent. Then, as the gear rotates, it leaves the vent. At this time, the dust blocking the vent is squeezed out by the cleaning brush head, which further improves the cleaning effect of the vent. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-4This utility model provides a technical solution: a dustproof feeding station, including a feeding bin 1 and a storage bin 5 disposed within the feeding bin 1. A connecting ring is welded to the inner wall of the feeding bin 1. The outer wall of the storage bin 5 is connected to the inner wall of the connecting ring. A ventilation opening 6 is provided inside the storage bin 5. A slot 501 is also provided on the storage bin 5. A drive motor 7 and an internal gear ring 8 are disposed in the slot 501. A column is connected to the inner bottom wall of the slot 501. The other end of the column is connected to the bottom wall of the internal gear ring 8. There are three columns, arranged around the bottom wall of the internal gear ring 8. An arc-shaped groove 11 is provided on the inner bottom wall of the slot 501. An arc-shaped block 13 is slidably connected in the arc-shaped groove 11. The top surface of the arc-shaped block 13 is connected to the bottom surface of the drive motor 7. A gear 9 is meshed on the internal gear ring 8. The drive end of the motor 7 is connected to the bottom surface of the gear 9. When the drive motor 7 is started, it drives the gear 9, which is fixedly connected to it, to rotate synchronously. The gear 9 not only rotates on its own axis, but also rotates around the internal gear ring 8 in the slot 501. The top wall of the gear 9 is connected to the connecting shaft 10, and the other end of the connecting shaft 10 is rotatably set in the slot 501. A cleaning brush head 12 is set on the connecting shaft 10. One end of the cleaning brush head 12 abuts against the inner wall of the slot 501. Since one end of the cleaning brush head 12 is always in close contact with the inner wall of the slot 501, during continuous rotation, when it passes the vent 6, the extended bristles will accurately insert into the vent 6. As the gear 9 continues to rotate, the cleaning brush head 12 will clean each vent 6 in turn, effectively reducing the blockage of the vent 6.

[0024] In practice, the drive motor 7 is started, which drives the gear 9 to rotate. Since the gear 9 is meshed with the internal gear ring 8, the gear 9 will rotate in the slot 501. The bottom surface of the connecting shaft 10 is connected to the gear 9. The cleaning brush head 12 on the connecting shaft 10 will rotate with the gear 9 and make a circular motion in the slot 501. One end of the cleaning brush head 12 abuts against the inner wall of the slot 501. During the rotation, it will insert into the vent 6 to clear the vent 6, reduce the blockage of the vent 6, and improve the efficiency of the blower 4.

[0025] It should be noted that a microcontroller is installed outside the feeding hopper 1 to control the start and speed of the drive motor 7. Since this is existing technology, it will not be described in detail in this manual, nor is it shown in the figure.

[0026] See Figure 3 as well as Figure 4 As shown, a hollow cylinder is sleeved on the connecting shaft 10, and a cleaning brush head 12 is set on the hollow cylinder. The cleaning brush head 12 is conical in shape, and the tip of the cone faces away from the end of the connecting shaft 10. During continuous rotation, when passing the vent 6, the bristles can penetrate into different depths inside the vent 6 to scrape and agitate the material particles and dust remaining on the inner wall of the vent 6, thereby improving the cleaning effect of the device.

[0027] In practice, the cleaning brush head 12 is cone-shaped with its tip facing the vent 6. When the cleaning brush head 12 cleans the vent 6, its tip will first enter the vent 6. Then, as the cleaning brush head 12 moves further in, the larger diameter end of the cleaning brush head 12 will also enter the vent 6. The outer wall of the larger diameter end of the cleaning brush head 12 will abut against the inner wall of the vent 6. Then, as the gear 9 rotates, it will leave the vent 6. At this time, the dust blocking the vent 6 will be squeezed out by the cleaning brush head 12, which will further improve the cleaning effect of the vent 6.

[0028] See Figure 1 A blower 4 is installed outside the feeding hopper 1. When the blower 4 is started, a connecting pipe 401 is installed on the blower 4. The connecting pipe 401 extends through the outer wall of the feeding hopper 5 and into the empty trough 501. The end of the connecting pipe 401 away from the blower 4 is connected to a blower head 403. The generated high-pressure airflow is delivered to the blower head 403 through the connecting pipe 401 and blows air into the empty trough 501. The airflow enters the feeding hopper 5 through the ventilation port 6, reducing dust on the material bags in the feeding hopper 5. At the same time, the slightly positive pressure environment formed by the airflow in the empty trough 501 can effectively prevent external dust backflow and extend the equipment maintenance cycle. A support frame 2 is connected to the outer wall of the feeding hopper 1. The support frame 2 is placed on the ground. A placement plate 402 is connected to the outer wall of the support frame 2. The blower 4 is bolted to the placement plate 402.

[0029] It should be noted that a dust collection device is also installed inside the empty trough 501, including a dust collection box. The dust collection box contains a micro motor, an impeller connected to the drive end of the micro motor, and a filter plate. The micro motor drives the impeller to rotate, which promotes air circulation inside the empty trough 501. After the blower 4 stops and the vent 6 is cleaned, the dust collection device is started to suck the dust into the filter plate inside the dust collection box. The dust is then processed on the filter plate, and the dust that falls into the empty trough 501 is recycled to prevent dust from accumulating in the arc-shaped groove 11 or affecting the device inside the empty trough 501, thereby improving the service life of the device. Since this is an existing device, it will not be described in detail in this instruction manual, and it is also not shown in the figure.

[0030] See Figure 1 The top of the feeding bin 1 is equipped with a cover plate 3, which is installed on the feeding bin 1 by a hinge, so as to facilitate the opening and closing of the cover plate 3 and the operation of the material bag.

[0031] It is worth mentioning that the inner wall of the material storage bin 5 is equipped with a cutter for cutting open the material bag. The bottom surface of the material storage bin 5 is equipped with a baffle that opens and closes. The top of the feeding bin 1 is also equipped with a filter screen to block the dust overflowing from the material storage bin 5. Since this is existing technology, it will not be elaborated on in this description.

[0032] Working principle: Starting the drive motor 7 drives the gear 9 to rotate. Since the gear 9 meshes with the internal gear ring 8, it rotates within the slot 501. The bottom surface of the connecting shaft 10 is connected to the gear 9. The cleaning brush head 12 on the connecting shaft 10 rotates along with the gear 9, making circular motions within the slot 501. One end of the cleaning brush head 12 abuts against the inner wall of the slot 501. During rotation, it inserts into the ventilation opening 6, clearing blockages and reducing clogging, thus improving the efficiency of the blower 4. When cleaning the ventilation opening 6, the brush head 12 is cone-shaped with its tip pointing towards the vent 6. When the brush head 12 cleans the ventilation opening 6, its tip will first enter the ventilation opening 6. Then, as the brush head 12 moves further in, the larger diameter end of the brush head 12 will also enter the ventilation opening 6. The outer wall of the larger diameter end of the brush head 12 will abut against the inner wall of the ventilation opening 6. Then, as the gear 9 rotates, it will leave the ventilation opening 6. At this time, the dust blocking the ventilation opening 6 will be squeezed out by the brush head 12, further improving the cleaning effect of the ventilation opening 6.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
