Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, and in particular to a novel closed feeding and conveying spiral structure for preventing bridging. Background Technology

[0002] In the polyvinyl chloride paste resin industry, the process flow adopts the micro-suspension method, which uses emulsifiers and the feeding method is manual one batch at a time. This method wastes manpower. Therefore, a closed feeding system is added to reduce the number of manual feedings. A centralized feeding method is adopted, in which the raw materials used in 24 hours are put into the silo every day. The raw materials are added by weighing and screw conveying, which saves the manual one batch at a time process.

[0003] However, in the existing technology, due to the physical properties of the powder, it is very easy for it to clump in a humid and hot environment. During the production process, the powder needs to stay in the silo, which makes the conveying screw very easy to get clogged and may cause bridging in the silo. This requires manual disassembly of the screw for cleaning, resulting in other maintenance costs and powder waste. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that powder needs to stay in the silo, which makes the conveying screw very easy to get clogged and may cause bridging in the silo. This requires manual disassembly of the screw for cleaning, resulting in additional maintenance costs and powder waste. The invention proposes a new type of sealed feeding and conveying screw structure to prevent bridging.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel closed feeding and conveying spiral structure for preventing bridging, comprising a conveying bin, a fluidizer installed at the lower end of the conveying bin, pneumatic hammers fixedly connected to both sides of the conveying bin, a cover fixedly connected to the upper end of the conveying bin, a material bin fixedly connected to one side of the upper end of the cover, an installation frame fixedly connected to the upper end of the material bin, a second drive motor fixedly connected to the upper end of the installation frame, a drive shaft fixedly connected to the output end of the second drive motor, a connecting rod fixedly connected to the outer surface of the drive shaft, a fitting scraper provided inside the material bin, and the connecting rod fixedly connected to the fitting scraper.

[0006] Preferably, a slanted lever plate is fixedly connected to the lower end of the outer surface of the drive shaft, and the slanted lever plate is inclined.

[0007] Preferably, a dividing rod is fixedly connected to the lower middle part of the inner wall of the hopper, and the dividing rod is located between two inclined baffles.

[0008] Preferably, a motor frame is provided on one side of the conveying bin, and a No. 1 drive motor is fixedly connected inside the motor frame.

[0009] Preferably, an auger is rotatably connected inside the conveying chamber, and one end of the auger is fixedly connected to the output end of the No. 1 drive motor.

[0010] Preferably, the lower end of the conveying chamber is fixedly connected to a support leg, and a through groove is provided in the middle of the upper end of the support leg.

[0011] Preferably, the lower end of the conveying bin is fixedly connected to a discharge port on the side away from the hopper.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the powder inside the conveying bin is broken up by the pneumatic hammer and fluidizer. The fluidizer fills the powder with gas, reducing friction between them and preventing powder agglomeration and bridging. This ensures normal operation of the equipment, avoids damage, and saves on operating costs. The scraper continuously agitates the powder inside the bin, preventing agglomeration and ensuring normal material feeding. This achieves smooth powder flow. The fluidizing air generated by the fluidizer not only breaks up bridges but also provides nitrogen sealing for the powder bin, keeping the powder dry and achieving automatic powder conveying. This saves labor costs and increases the timeliness and accuracy of process operations.

[0014] 2. In this utility model, by setting the inclined baffle, the powder below the hopper can be crushed by the rotation of the drive shaft during use, and the powder can be pushed upward, so that the powder inside is always in a moving state. With the setting of the partition rod, the crushing effect can be increased to further avoid the powder from clumping. The powder is always in a moving state to avoid bridging. The setting of the through groove can facilitate the laying of fluidizer connection pipes, making it more convenient to use. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a novel closed feeding and conveying spiral structure for preventing bridging, including a conveying bin 1, a fluidizer 4 installed at the lower end of the conveying bin 1, pneumatic hammers 2 fixedly connected to both sides of the conveying bin 1, a cover 11 fixedly connected to the upper end of the conveying bin 1, a material bin 8 fixedly connected to one side of the upper end of the cover 11, a mounting frame 9 fixedly connected to the upper end of the material bin 8, a second drive motor 10 fixedly connected to the upper end of the mounting frame 9, a drive shaft 12 fixedly connected to the output end of the second drive motor 10, a connecting rod 16 fixedly connected to the outer surface of the drive shaft 12, a fitting scraper 15 provided inside the material bin 8, and the connecting rod 16 fixedly connected to the fitting scraper 15.

[0023] The specific settings and functions of this embodiment are described in detail below. The pneumatic hammer 2 and fluidizer 4 are used to break up the powder inside the conveying bin 1. The fluidizer 4 fills the powder particles with gas, reducing friction and preventing agglomeration and bridging, thus ensuring normal equipment operation, preventing damage, and saving operating costs. The scraper 15 continuously agitates the powder inside the hopper 8, preventing agglomeration and ensuring smooth material flow. This achieves smooth powder flow. The fluidizing air generated by the fluidizer 4 not only breaks up bridges but also provides nitrogen sealing for the powder hopper 8, keeping the powder dry and enabling automatic powder conveying. This saves labor costs and increases the timeliness and accuracy of process operations.

[0024] Example 2: Figure 1 - Figure 4 As shown, a slanted baffle plate 13 is fixedly connected to the lower end of the outer surface of the drive shaft 12. The slanted baffle plate 13 is inclined. A separator rod 14 is fixedly connected to the lower middle part of the inner wall of the hopper 8. The separator rod 14 is located between the upper and lower slanted baffle plates 13. A motor frame 6 is provided on one side of the conveying hopper 1. A first drive motor 7 is fixedly connected inside the motor frame 6. An auger 17 is rotatably connected inside the conveying hopper 1. One end of the auger 17 is fixedly connected to the output end of the first drive motor 7. A support leg 3 is fixedly connected to the lower end of the conveying hopper 1. A through groove 5 is opened in the middle of the upper end of the support leg 3. A discharge port is fixedly connected to the lower end of the conveying hopper 1 away from the hopper 8.

[0025] The overall effect of this embodiment is that, through the setting of the inclined baffle 13, the powder below the hopper 8 can be crushed by the rotation of the drive shaft 12 during use, and the powder is pushed upward, so that the powder inside is always in a moving state. With the setting of the separator 14, the crushing effect can be increased to further avoid the agglomeration of powder and keep the powder in a moving state to avoid bridging. The setting of the through groove 5 can facilitate the laying of the fluidizer 4 connecting pipe, making it more convenient to use.

[0026] The operating method and working principle of this device are as follows: When in use, the No. 1 drive motor 7 starts, driving the auger 17 to rotate and transport the powder inside the hopper 8 to the next processing step. When a certain amount is transported, the No. 1 drive motor 7 stops, and the No. 2 drive motor 10, pneumatic hammer 2 and fluidizer 4 are started to promote the flow of powder in the conveying bin 1 and the hopper 8, and prevent the powder from clumping. In this way, when conveying is required, the No. 2 drive motor 10, pneumatic hammer 2 and fluidizer 4 stop, and the No. 1 drive motor 7 starts, and the powder is transported in this cycle.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
