Description

Technical Field

[0001] This utility model relates to the field of screw feeder technology, specifically to an anti-clogging screw feeder for conveying slag. Background Technology

[0002] In industrial production, such as metallurgy, chemical industry, and power industry, it is often necessary to transport and process slag. Due to its advantages such as simple structure, small footprint, and ability to achieve closed conveying, the screw feeder has become one of the commonly used equipment for slag conveying.

[0003] However, existing screw feeders have many problems when conveying slag. Slag often has characteristics such as uneven particle size, irregular shape, and large changes in moisture content, which can easily accumulate and block at the feed inlet, outlet, and gap between the feeding auger and the inner wall of the cylinder, leading to reduced conveying efficiency or even equipment shutdown. In addition, some highly viscous slag can also adhere to the feeding auger and the inner wall of the cylinder, further affecting the conveying effect. Moreover, the cylinder of the screw feeder is usually fixed and cannot be disassembled, which affects the cleaning of the feeding auger by the workers. Utility Model Content

[0004] In view of the problems existing in the above-mentioned screw feeders, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an anti-clogging screw feeder for conveying slag, which solves the problem that existing screw feeders are prone to clogging at the feed inlet, and that it is difficult to clean when wet slag sticks to the feeding auger because its material cylinder is usually fixed and cannot be disassembled.

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

[0007] An anti-clogging screw feeder for conveying slag includes a base. Multiple first connecting rods are fixedly connected to the upper surface of the base. A first material cylinder is fixedly connected to the upper end of each first connecting rod. An electric slide rail is fixedly connected to the upper surface of the base. A slider is provided on the upper surface of the electric slide rail. Multiple second connecting rods are fixedly connected to the upper surface of the slider. A second material cylinder is fixedly connected to the upper end of each second connecting rod. A feeding auger is rotatably connected inside the first material cylinder. A driving mechanism is provided on one side of the first material cylinder, and the feeding auger rotates through the driving mechanism. A feed frame is provided on the upper surface of the first material cylinder. A stirring rod is rotatably connected inside the feed frame. A transmission mechanism is provided between the stirring rod and the driving mechanism, and the driving mechanism drives the stirring rod to rotate through the transmission mechanism.

[0008] Preferably, the driving mechanism includes a fixed frame and a motor. The fixed frame is fixedly connected to one side of the first material cylinder, the motor is fixedly connected to one side of the fixed frame, and one end of the feeding auger passes through one side of the fixed frame and is fixedly connected to the output end of the motor.

[0009] Preferably, the transmission mechanism includes a mounting plate, a rotating rod, two sprockets, a chain, and two bevel gears. The mounting plate is fixedly connected to one side of the upper surface of the feed frame. A through hole is opened on one side of the mounting plate. The rotating rod is rotatably connected to the inside of the through hole. The two sprockets are respectively fixedly sleeved on the rod wall of the rotating rod and one end of the feeding auger. The chain is sleeved on the outer surface of the two sprockets. The two bevel gears are respectively fixedly connected to the rod wall of the rotating rod and one end of the stirring rod and mesh with each other.

[0010] Preferably, an annular plate is fixedly connected to one end of the second material cylinder, and an annular groove is formed on one side of the first material cylinder, with the annular plate matching the annular groove.

[0011] Preferably, a discharge pipe is provided below one end of the second material cylinder.

[0012] Preferably, a plurality of third support rods are fixedly connected between the feed frame and the first material cylinder.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. In this utility model, the feeding auger set inside the first material cylinder has a small pitch of the spiral blades near the feed frame, which increases the pushing force on the slag, allowing the slag to quickly enter the first material cylinder and be initially compacted. At the same time, the slag is stirred by the stirring rod, thus preventing the slag from accumulating at the feed inlet. As the feeding auger extends towards the second material cylinder, the pitch gradually increases. This design helps the slag to gradually loosen during the conveying process and avoids blockage due to over-compaction.

[0015] 2. In this utility model, by starting the motor, the feeding auger is rotated, and then the rotating rod is rotated by the transmission of two sprockets and chains, which in turn rotates the bevel gear connected to the rotating rod, which in turn drives another bevel gear to rotate, thereby allowing the stirring rod to rotate.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses an anti-clogging screw feeder for conveying slag.

[0024] This utility model provides, for example Figure 1-3 The illustrated anti-clogging screw feeder for conveying slag includes a base 1. Multiple first connecting rods 2 are fixedly connected to the upper surface of the base 1. A first material cylinder 3 is fixedly connected to the upper end of each first connecting rod 2. An electric slide rail 4 is fixedly connected to the upper surface of the base 1. A slider 5 is provided on the upper surface of the electric slide rail 4. Multiple second connecting rods 6 are fixedly connected to the upper surface of the slider 5. A second material cylinder 14 is fixedly connected to the upper end of each second connecting rod 6. A feeding auger 18 is rotatably connected inside the first material cylinder 3. A driving mechanism is provided on one side of the first material cylinder 3, and the feeding auger 18 rotates through the driving mechanism. A feed frame 19 is provided on the upper surface of the first material cylinder 3. A stirring rod 20 is rotatably connected inside the feed frame 19. A transmission mechanism is provided between the stirring rod 20 and the driving mechanism, and the driving mechanism drives the stirring rod 20 to rotate through the transmission mechanism. A discharge pipe 16 is provided below one end of the second material cylinder 14.

[0025] Near the feed frame 19, the pitch of the spiral blades of the feeding auger 18 is relatively small, which increases the pushing force on the slag, allowing the slag to quickly enter the first material cylinder 3 and be initially compacted. At the same time, the stirring rod 20 is used to stir the slag, thus preventing the slag from accumulating at the feed inlet. As the feeding auger 18 extends towards the second material cylinder 14, the pitch gradually increases. This design helps the slag to gradually loosen during the conveying process and avoids blockage due to over-compaction. When it is necessary to clean the feeding auger, the electric slide rail 4 is activated, which then moves the second material cylinder 14 to facilitate the cleaning work of the staff.

[0026] To make the feeding auger 18 rotate, such as Figure 1-2 As shown, the driving mechanism includes a fixed frame 7 and a motor 8. The fixed frame 7 is fixedly connected to one side of the first material cylinder 3, and the motor 8 is fixedly connected to one side of the fixed frame 7. One end of the feeding auger 18 passes through one side of the fixed frame 7 and is fixedly connected to the output end of the motor 8.

[0027] The feeding auger 18 can be driven to rotate by the motor 8.

[0028] To make the stirring rod 20 rotate, such as Figure 1-3 As shown, the transmission mechanism includes a mounting plate 9, a rotating rod 10, two sprockets 11, a chain 12, and two bevel gears 13. The mounting plate 9 is fixedly connected to one side of the upper surface of the feed frame 19. A through hole is opened on one side of the mounting plate 9. The rotating rod 10 is rotatably connected to the inside of the through hole. The two sprockets 11 are respectively fixedly sleeved on the rod wall of the rotating rod 10 and the feeding auger 18 at one end. The chain 12 is sleeved on the outer surface of the two sprockets 11. The two bevel gears 13 are respectively fixedly connected to the rod wall of the rotating rod 10 and the stirring rod 20 at one end and mesh with each other.

[0029] Start the motor 8 to make the feeding auger 18 rotate. Then, the two sprockets 11 and the chain 12 will drive the rotating rod 10 to rotate, which will cause the bevel gear 13 connected to the rotating rod 10 to rotate. Then, it can drive another bevel gear 13 to rotate, which will allow the stirring rod 20 to rotate.

[0030] In order to ensure a tight connection between the second material cylinder 14 and the first material cylinder 3, such as Figure 2 As shown, an annular plate 15 is fixedly connected to one end of the second material cylinder 14, and an annular groove is provided on one side of the first material cylinder 3. The annular plate 15 matches the annular groove.

[0031] Inserting the annular plate 15 into the annular groove can improve the stability between the first material cylinder 3 and the second material cylinder 14, so that the second material cylinder 14 and the first material cylinder 3 can be tightly connected.

[0032] To ensure the stability of the feed frame 19, such as Figure 1-2As shown, a plurality of third support rods 17 are fixedly connected between the feed frame 19 and the first material cylinder 3.

[0033] The feed tube 19 can be stabilized by using each third support rod 17.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
