Technical Field

[0001] This utility model relates to the technical field of dust-free feeding stations, specifically a special-shaped dual-channel feeding pipe for a dust-free feeding station. Background Technology

[0002] A cleanroom feeding station (also known as a cleanroom feeding system or a closed feeding station) is a specialized piece of equipment used in industrial production to safely, cleanly, and efficiently transfer powdery or granular materials from packaging containers (such as bags or drums) to downstream equipment (such as reactors, mixers, and silos). Its core functions are to prevent dust escape, protect the health of operators, avoid environmental pollution, and ensure the cleanliness of the production process.

[0003] Currently, cleanroom feeding stations typically employ a dual-channel design for their feeding pipes to prevent dust from being stirred up during the feeding process. One channel is used for feeding, while the other is used for ventilation. However, this structure still suffers from pipe blockage, which affects the efficiency of material feeding and requires improvement. Utility Model Content

[0004] The purpose of this invention is to provide a non-standard dual-channel feeding pipe for a dust-free feeding station, so as to solve the problem of easy blockage and low feeding efficiency of the feeding pipe in the dust-free feeding station mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special-shaped dual-channel feeding pipe for a dust-free feeding station, including a fixed frame, a dust-free feeding box fixedly connected to the top of the fixed frame, a feeding pipe provided at the bottom of the dust-free feeding box, a negative pressure pump fixedly connected to the bottom side of the fixed frame, a connecting pipe connected to one side of the feeding pipe, one end of the connecting pipe connected to the negative pressure pump, a support net and a non-woven mesh fixedly connected to the inner wall of the connecting pipe, a vibrating plate inserted into the inner wall of the feeding pipe, a vibration motor installed on the inner wall of the vibrating plate, a first connecting rod connected to one end of the vibrating plate, a connecting block connected to one end of the first connecting rod, a bouncing ball provided on the outer wall of the connecting block, and the bouncing ball adhering to the inner wall of the non-woven mesh.

[0006] Preferably, the inner wall of the feeding pipe has an opening, and a vibrating plate is inserted and fixed inside the opening.

[0007] Preferably, the connecting pipe has an inclined structure and is equipped with a solenoid valve.

[0008] Preferably, one end of the support net is provided with a non-woven mesh, and the outer ring of the non-woven mesh is glued and fixed to the support net.

[0009] Preferably, the vibrating plate has a right-angled "U" shape when viewed from above, and the vibrating plate is fixedly connected to the first connecting rod, which is made of an elastic material.

[0010] Preferably, one end of the first connecting rod is fixedly connected to a connecting block, the top and bottom of the connecting block are both sharp structures, and multiple second connecting rods are distributed at equal intervals around the outer wall of the connecting block.

[0011] Preferably, the bouncing balls are made of rubber, and multiple bouncing balls are provided.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device can ensure the smooth flow of material feeding and avoid material blockage, thereby improving the material feeding efficiency.

[0014] (2) This device sets an automatic vibrating second connecting rod and a ball inside the feeding pipe. The vibration of the second connecting rod and the ball can not only accelerate the feeding of materials in the feeding pipe, but also beat the non-woven mesh, thereby avoiding the blockage of the non-woven mesh and affecting the negative pressure adsorption effect.

[0015] (3) This device sets a connecting pipe on one side of the feeding pipe and connects a negative pressure pump to one end of the connecting pipe. The negative pressure pump and the connecting pipe can be used to use negative pressure adsorption to accelerate the feeding of materials and reduce the occurrence of material dust.

[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: a non-standard dual-channel feeding pipe for a dust-free feeding station, including a fixed frame 2. A dust-free feeding box 1 is fixedly connected to the top of the fixed frame 2. A feeding pipe 10 is provided at the bottom of the dust-free feeding box 1. An opening is provided on the inner wall of the feeding pipe 10, and a vibrating plate 14 is inserted and fixed inside the opening. The vibrating plate 14 and the feeding pipe 10 are fixed with screws. A negative pressure pump 5 is fixedly connected to the bottom side of the fixed frame 2. The negative pressure pump 5 is pulse-controlled by a PLC, thereby improving the smoothness of material feeding. A connecting pipe 4 is connected to one side of the feeding pipe 10. The connecting pipe 4 has an inclined structure and is equipped with a solenoid valve. 3. The solenoid valve 3 in this structure is controlled by a PLC to automatically control the opening and closing of the connecting pipe 4. One end of the connecting pipe 4 is connected to the negative pressure pump 5. A support net 8 and a non-woven mesh 9 are fixedly connected to the inner wall of the connecting pipe 4. The non-woven mesh 9 is installed at one end of the support net 8, and the outer ring of the non-woven mesh 9 is glued and fixed to the support net 8. This structure, through the non-woven mesh 9 and the support net 8, ensures airflow while intercepting materials to prevent materials from entering the connecting pipe 4. The support net 8 supports the non-woven mesh 9 to prevent it from breaking under negative pressure. A vibrating plate 14 is inserted into the inner wall of the feed pipe 10. The vibrating plate 14, viewed from above, has a right-angled "U" shape. The vibrating plate 14 is fixedly connected to the first connecting rod 7, which is made of elastic material. This structure allows vibration to be transmitted to the first connecting rod 7 via the vibrating plate 14, thereby causing the second connecting rod 11 and the bouncing ball 12 on the first connecting rod 7 to vibrate. A connecting block 6 is fixedly connected to one end of the first connecting rod 7. The top and bottom of the connecting block 6 are both sharp. Multiple second connecting rods 11 are evenly distributed around the outer wall of the connecting block 6. This structure allows for convenient installation of multiple second connecting rods 11 via the connecting block 6, while also ensuring smooth material feeding and preventing material accumulation. A vibration motor 13 is installed on the inner wall, which can drive the vibrating plate 14 and the first connecting rod 7 to vibrate automatically. One end of the vibrating plate 14 is connected to the first connecting rod 7, and the other end of the first connecting rod 7 is connected to the connecting block 6. A ball 12 is provided on the outer wall of the connecting block 6. The ball 12 is made of rubber and there are multiple balls 12. This structure allows the balls 12 to beat the non-woven fabric 9 and the material, thereby accelerating the feeding and separation of the material. The balls 12 are attached to the inner wall of the non-woven fabric 9. The dust-free feeding box 1 of this device has a feeding port. This part is existing technology, so it will not be described in detail here.

[0023] Working principle: When using the special-shaped dual-channel feeding pipe of the dust-free feeding station, the material is first added into the dust-free feeding box 1. Under the negative pressure adsorption of the negative pressure pump 5, the material moves into the lower feeding pipe 10. At the same time, the vibration motor 13 drives the vibrating plate 14 and the first connecting rod 7 to vibrate. During the vibration, the first connecting rod 7 drives the second connecting rod 11 and the ball 12 to vibrate, so that the ball 12 can smoothly feed the material and beat the non-woven mesh 9 to avoid clogging on the surface of the non-woven mesh 9. While adsorbing the material, the negative pressure pump 5 also intercepts the material through the non-woven mesh 9, so that the material can fall smoothly after the negative pressure pump 5 is turned off.

[0024] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
