Description

Technical Field

[0001] This utility model relates to the field of chemical filling technology, specifically a spiral feeder for chemical filling. Background Technology

[0002] Automatic screw feeders are mainly used for feeding powder and granular materials. They are suitable for feeding equipment with certain high requirements in industries such as food, chemical, building materials, plastics and packaging, and are widely used in existing chemical filling processes.

[0003] Patent publication number CN216917421U discloses a screw feeder for chemical filling, comprising a feeding box, a conveying cylinder fixedly mounted at the lower end of the feeding box, and the conveying cylinder communicating with the bottom of the feeding box. The conveying cylinder includes two symmetrically arranged semi-cylinders connected by multiple first bolt assemblies. A fixing plate is fixedly mounted at the lower end of the semi-cylinders, and a drive shaft rotatably passes through the fixing plate. The drive shaft is connected by multiple drive rods connected end-to-end, all located inside the conveying cylinder, with a screw blade fixedly sleeved on the outer side. A discharge pipe is connected to the upper end of the conveying cylinder, and a drive mechanism for driving the drive shaft to rotate is provided at the lower end of the conveying cylinder. A connecting mechanism is provided between adjacent drive rods. Multiple spaced through slots are opened at the top of the semi-cylinders. This application allows for real-time observation and convenient disassembly and replacement of the screw blades inside the feeder during chemical filling.

[0004] However, although the spiral blades can be disassembled and replaced, they are generally fixed in actual use, making cleaning inconvenient. Over time, material residue on the surface affects the feeding efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a screw feeder for chemical filling, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A screw conveyor for chemical filling includes a fixed frame and a feeding cylinder. A three-way pipe is fixedly connected to the lower top of the feeding cylinder, and a water outlet pipe is fixedly connected to the lower bottom of the feeding cylinder. Multiple pistons are arranged on the upper top of the feeding cylinder, and a motor is fixedly connected to the upper bottom of the feeding cylinder. A rotating rod is fixedly connected to the output end of the motor. Two upper pulleys are fixedly sleeved on the surface of the rotating rod, and a belt is drivingly connected between the two upper pulleys. Lower pulleys are drivingly connected to both sides of the lower part of the belt, and a drive rod is fixedly connected to the inner side of the two lower pulleys. A threaded conveying rod is fixedly connected to one end of the drive rod.

[0008] Preferably, one end of the threaded conveyor rod is rotatably connected to the inner side of the feed cylinder.

[0009] Preferably, one end of the drive rod rotates through and extends into the inside of the feeding cylinder.

[0010] Preferably, a first valve and a second valve are rotatably connected to both sides of the three-way pipe, and a third valve is rotatably connected to the surface of the outlet pipe.

[0011] Preferably, a retaining ring is fixedly connected to the piston surface.

[0012] Preferably, a feeding hopper is fixedly connected to the top of the fixed frame, the bottom of the feeding hopper is fixedly connected to the surface of the feeding cylinder, and two support plates of different lengths are fixedly connected to the bottom of the feeding cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In use, this invention addresses the issue of residual material remaining on the screw conveyor during the feeding process. Over time, without cleaning, this affects feeding efficiency. To resolve this, the fixing ring is pulled upwards, causing pistons to move out of the feeding cylinder. Each piston is then removed using this method. The first valve is then closed, and the second and third valves are opened. The motor is then turned on again, and a water pipe is inserted into the pulled-out hole to pump water into the feeding cylinder. As the motor rotates the screw conveyor, water is distributed to various positions on the screw conveyor for cleaning. Due to the downward flow of water, some of the wastewater is discharged through the outlet pipe. Simultaneously, because the screw conveyor transports materials upwards, some water also moves upwards and is discharged through the open side of the second valve on the three-way pipe.

[0018] 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.

[0019] Please see Figure 1-2This utility model provides a technical solution: a spiral feeder for chemical filling, including a fixed frame 1 and a feeding cylinder 4. A three-way pipe 6 is fixedly connected to the lower top of the feeding cylinder 4. A first valve 7 and a second valve 8 are rotatably connected to both sides of the three-way pipe 6. A water outlet pipe 9 is fixedly connected to the lower bottom of the feeding cylinder 4. A third valve 10 is rotatably connected to the surface of the water outlet pipe 9. Multiple pistons 11 are arranged on the upper top of the feeding cylinder 4. A fixing ring 12 is fixedly connected to the surface of the pistons 11. A motor 5 is fixedly connected to the upper bottom of the feeding cylinder 4. A rotating rod 14 is fixedly connected to the output end of the motor 5. Two upper pulleys 15 are fixedly sleeved on the surface of the rotating rod 14. The two upper pulleys 15 are connected for transmission. A belt 16 is connected to a drive belt. Lower pulleys 17 are connected to both sides of the lower part of the belt 16. Drive rods 18 are fixedly connected to the inner sides of the two lower pulleys 17. A threaded conveyor rod is fixedly connected to one end of the drive rod 18. One end of the threaded conveyor rod is rotatably connected to the inner side of the upper feed cylinder 4. One end of the drive rod 18 rotatably passes through and extends into the upper feed cylinder 4. First, the left side of the three-way pipe 6 is connected to the material filling structure to facilitate filling. The right side of the three-way pipe 6 and the water outlet pipe 9 are connected to the recovery water pipe for recycling the wastewater generated during cleaning. Then, the motor 5 is started, the first valve 7 is opened, and the second valves 8 and 9 are closed. The motor 5 will drive the upper pulley 15. The rotation of the screw conveyor 13 causes the belt 16 to rotate, which in turn drives the lower pulley 17 to rotate, which in turn drives the drive rod 18 to rotate, and finally drives the screw conveyor 13 to rotate. This allows the falling material to move to the top of the upper feed cylinder 4 until it reaches the position of the three-way pipe 6. The material will then fall into the processing device for processing through the open side of the first valve 7 of the three-way pipe 6. After the material is fed, the motor 5 is turned off. During the feeding process, some residual material will remain on the screw conveyor 13. If it is not cleaned over time, it will affect the material feeding efficiency. Therefore, by pulling the fixing ring 12 upward, the fixing ring 12 will drive the piston 11 to move out of the feed cylinder 4. The method involves removing each piston 11, closing the first valve 7, opening the second valve 8, turning on the motor 5 again, inserting the water pipe into the pulled-out hole, and feeding water into the feeding cylinder 4. As the motor 5 drives the screw conveyor 13 to rotate, water can be transported to various positions of the screw conveyor 13 for cleaning. Due to the downward flow of water, some of the cleaning wastewater is discharged through the outlet pipe 9. At the same time, because the screw conveyor 13 conveys materials upward, some water will also move upward. The upward-moving water will be discharged through the open side of the second valve 8 of the three-way pipe 6. After cleaning is completed, the piston 11 is pushed back into its original position.

[0020] like Figure 1 As shown, a feeding hopper 3 is fixedly connected to the top of the fixed frame 1. The bottom of the feeding hopper 3 is fixedly connected to the surface of the feeding cylinder 4. Two support plates 2 of different lengths are fixedly connected to the bottom of the feeding cylinder 4. Materials are fed in through the feeding hopper 3.

[0021] Working principle: When in use, first connect the left side of the three-way pipe 6 to the material filling structure to facilitate filling. Connect the right side of the three-way pipe 6 and the water outlet pipe 9 to the recycling water pipe to recycle the wastewater generated during cleaning.

[0022] Then start motor 5, open first valve 7, close second valve 8 and second valve 9, and feed material into feeding hopper 3. The material will fall into feeding cylinder 4 through feeding hopper 3. At this time, motor 5 will drive upper pulley 15 to rotate, thereby driving belt 16 to rotate, then driving lower pulley 17 to rotate, then driving drive rod 18 to rotate, and finally driving screw conveyor 13 to rotate, thereby driving the falling material to move to the top of feeding cylinder 4 until it moves to the position of three-way pipe 6. The material will fall into processing device for processing through the side of first valve 7 of three-way pipe 6. After feeding is completed, turn off motor 5.

[0023] During the feeding process, residual material may remain on the screw conveyor 13. If this material is not cleaned over time, it will affect the feeding efficiency. Therefore, by pulling the fixing ring 12 upward, the fixing ring 12 will drive the piston 11 to move out of the feeding cylinder 4. By moving each piston 11 out in this way, the first valve 7 is closed, and the second valve 8 is opened. The motor 5 is then turned on again, and the water pipe is inserted into the pulled-out hole to input water into the feeding cylinder 4. As the screw conveyor 13 rotates under the action of the motor 5, the water can be delivered to each position of the screw conveyor 13 for cleaning. According to the characteristic that water flows downward, some of the cleaning wastewater is discharged through the outlet pipe 9. At the same time, because the screw conveyor 13 conveys materials upward, some water will also move upward. The upward-moving water will be discharged through the open side of the second valve 8 of the three-way pipe 6. After cleaning is completed, the piston 11 is put back in its original position.

[0024] The above operations can be used to clean the screw conveyor rod 13.
