Description

Technical Field

[0001] This utility model relates to the field of lithium battery feeding technology, specifically to an anti-clogging screw conveyor device. Background Technology

[0002] Screw conveyors are important conveying equipment. Their working principle is mainly based on the motor driving the screw shaft to rotate, and the screw blades on the screw shaft push the material to achieve material conveying.

[0003] refer to Figure 2 In the existing technology, during the process of conveying crushed lithium battery materials, the end of the screw shaft of the screw conveyor is fixed in the discharge port of the conveying cylinder through a fixed structure. As a result, the material tends to adhere to the fixed structure and the end of the screw shaft during the process of entering the pyrolysis furnace, which leads to poor conveying and low conveying efficiency. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides an anti-blocking screw conveyor device, which solves the problem of low conveying efficiency in the process of conveying materials to the pyrolysis furnace by existing screw conveyors.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A clogging-resistant screw conveyor device is provided, comprising a screw conveyor, the screw conveyor including a hollow conveying cylinder with an open end, the open end of the conveying cylinder being connected to the feed inlet of a pyrolysis furnace, and a feed cylinder being provided on the top of the closed end of the conveying cylinder; a hollow screw shaft is provided inside the conveying cylinder, the screw shaft being provided with multiple screw blades, one end of the screw shaft being fixedly connected to one end of a drive shaft, the other end of the drive shaft passing through the closed end of the conveying cylinder and being connected to a motor for transmission, and a gap being left between the other end of the screw shaft and the open end of the conveying cylinder.

[0007] The beneficial effects of this solution are as follows: By maintaining a gap between the free end of the screw shaft and the open end of the conveying cylinder, a hollow area is created at the open end of the conveying cylinder. This hollow area prevents material adhesion, avoiding the problem of material adhering to fixed structures or bolt ends caused by the direct fixed connection between the screw shaft and the open end of the conveying cylinder in traditional structures, thus improving conveying efficiency. Furthermore, as the material moves to the hollow area of ​​the conveying cylinder and accumulates under the push of the screw blades, it is subjected to a certain amount of compressive force during free accumulation under the influence of the screw blades. This compaction not only improves conveying efficiency but also makes the material more stable during conveying, reducing conveying failures caused by loose material. The hollow design of the screw shaft reduces weight and rotational inertia, improving energy utilization efficiency.

[0008] Furthermore, the screw shaft includes multiple detachable and fixedly connected sections, each with a fixed screw blade. This multi-section configuration allows for flexible adjustment of the screw shaft's length to suit different material properties (such as viscosity and particle size), enhancing the equipment's applicability.

[0009] Furthermore, the conveying cylinder includes an upper cylinder cover plate and a lower cylinder cover plate bolted together. The feed cylinder is located on one end of the top surface of the upper cylinder cover plate, and a disassembly cover plate is located on the other end of the top surface of the upper cylinder cover plate. The disassembly cover plate provides a quick maintenance channel, allowing for the handling of sudden blockages without completely disassembling the equipment, thus reducing downtime.

[0010] Furthermore, the screw conveyor is mounted on top of a fixed support, and multiple leveling feet are provided on the bottom of the fixed support. The leveling feet facilitate the adjustment of the levelness of the entire device.

[0011] Furthermore, the motor is mounted on a fixed bracket, and its output shaft is connected to the drive shaft via a chain drive. Compared to gear drives, chain drives offer better overload protection and can withstand the instantaneous jamming impact of the helical shaft.

[0012] Furthermore, the drive shaft is rotatably mounted on the fixed bracket via two fixed bearings located on the fixed bracket. The two fixed bearings distribute the load, significantly reducing the load on each individual bearing and extending its service life.

[0013] Furthermore, the drive shaft is rotatably mounted on the conveyor cylinder via a sealed bearing located at the closed end of the conveyor cylinder. The sealed bearing prevents material from overflowing from the gap between the closed end of the conveyor cylinder and the drive shaft.

[0014] Furthermore, the distance between the free end of the screw shaft and the open end of the conveying cylinder is 20cm to 50cm.

[0015] Furthermore, the cover plate is made of transparent acrylic sheet. The transparent acrylic material enables visual monitoring, allowing operators to observe the material flow status inside the cylinder in real time. Attached Figure Description

All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0020] refer to Figure 1 In order to solve the problem of low conveying efficiency in the process of conveying materials to the pyrolysis furnace 700 by existing screw conveyors, this application provides an anti-blocking screw conveyor device, which includes a screw conveyor, and is shown in detail below.

[0021] The screw conveyor includes a conveying cylinder 100, which is hollow inside and open at one end, including an open end and a closed end. The open end of the conveying cylinder 100 is used to communicate with the feed port of the pyrolysis furnace 700, and a feed cylinder 111 for material entry is provided on the top of the closed end of the conveying cylinder 100.

[0022] A hollow spiral shaft 200 is provided inside the conveying cylinder 100. The hollow design of the spiral shaft 200 reduces weight, lowers rotational inertia, and improves energy utilization efficiency. Multiple spiral blades 300 are provided on the spiral shaft 200. One end of the spiral shaft 200 is fixedly connected to one end of a drive shaft 400, and the other end of the drive shaft 400 passes through the closed end of the conveying cylinder 100 and is connected to a motor 500 for transmission. A gap is left between the other end of the spiral shaft 200 and the open end of the conveying cylinder 100. To prevent material from overflowing from the gap between the closed end of the conveying cylinder 100 and the drive shaft 400, a sealed bearing 42 is provided on the closed end of the conveying cylinder 100. The drive shaft 400 is rotatably mounted on the conveying cylinder 100 via the sealed bearing 42 on the closed end of the conveying cylinder 100. In this embodiment, the distance between the free end of the spiral shaft 200 and the open end of the conveying cylinder 100 is 20cm to 50cm. Preferably, the spiral shaft 200 may include multiple detachably fixed connecting sections, each of which is fixed with one spiral blade 300. The multi-segment configuration of the spiral shaft 200 can adjust the distance between the free end of the spiral shaft 200 and the open end of the conveying cylinder 100 according to actual needs.

[0023] As a further embodiment, the conveying cylinder 100 includes an upper cylinder cover plate 11 and a lower cylinder cover plate 12 bolted together. The feed cylinder 111 is disposed on one end of the top surface of the upper cylinder cover plate 11, and a disassembly cover plate 112 is disposed on the other end of the top surface of the upper cylinder cover plate 11. The disassembly cover plate 112 is made of transparent acrylic sheet and provides a quick maintenance channel, allowing for handling of sudden blockages without completely disassembling the equipment, thus reducing downtime.

[0024] To facilitate adjustment of the overall level of the device, the screw conveyor is mounted on top of the fixed support 600, and multiple leveling feet 61 are provided on the bottom of the fixed support 600. In this embodiment, the motor 500 is mounted on the fixed support 600, and the output shaft of the motor 500 is connected to the transmission shaft 400 via chain drive. Compared with gear drive, chain drive has better overload protection characteristics and can withstand the instantaneous jamming impact of the screw shaft 200.

[0025] To facilitate the rotation of the drive shaft 400, two fixed bearings 41 are provided on the fixed bracket 600, and the drive shaft 400 is rotatably mounted on the fixed bracket 600 via the two fixed bearings 41.

[0026] In summary, the beneficial effects of this plan are as follows:

[0027] By maintaining a gap between the free end of the spiral shaft 200 and the open end of the conveying cylinder 100, a hollow area is created at the open end of the conveying cylinder 100. This hollow area prevents material adhesion and avoids the problem of material adhering to fixed structures or bolt ends caused by the direct fixed connection between the spiral shaft 200 and the open end of the conveying cylinder 100 in traditional structures, thus improving conveying efficiency. Furthermore, as the material moves to the hollow area of ​​the conveying cylinder 100 and accumulates under the push of the spiral blades 300, it is subjected to a certain amount of compressive force during free accumulation under the influence of the spiral blades 300. This compaction not only improves conveying efficiency but also makes the material more stable during conveying, reducing conveying failures caused by loose material.
