Description

Technical Field

[0001] This patent relates to the field of slag discharge machine technology, specifically an anti-clogging spiral slag discharge machine. Background Technology

[0002] The slag discharged from the boiler needs to be cooled by a slag cooler and then transported away by a spiral slag discharger. The existing slag discharger is horizontally placed and there is a certain gap between the blades of the spiral shaft and the inner wall of the shell. During the transportation process, the slag fragments in the slag are easy to accumulate at the bottom of the inner wall of the slag discharger. Over time, the accumulation can easily cause blockage of the spiral shaft. Therefore, we propose an anti-blockage spiral slag discharger. Utility Model Content

[0003] The purpose of this patent is to provide an anti-clogging spiral slag discharge machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this patent provides the following technical solution: an anti-clogging spiral slag discharge machine, comprising a spiral slag discharge machine body and a base. The top of the shell of the spiral slag discharge machine body is embedded with a slag inlet pipe. A connecting plate is fixedly installed at the bottom of the shell of the spiral slag discharge machine body. Hinge seats are fixedly installed at both the front and rear ends of the bottom left side of the connecting plate. A hinge seat is fixedly installed at the bottom right side of the connecting plate. Support rods are fixedly installed at both the front and rear ends of the top left side of the base. The top ends of the support rods are hinged in the hinge seats. A motor is fixedly installed on the top right side of the base. A turntable is fixedly installed at the front end of the motor shaft. A swing rod is hinged to the lower side of the front side of the turntable. The top end of the swing rod is hinged in the hinge seats.

[0005] The hinge includes a U-shaped seat, a bolt, and a nut. The right end of the bolt extends through the U-shaped seat and the rocker arm to the right side of the U-shaped seat. The nut includes an internal threaded ring and a pressure ring. The internal threaded ring is screwed onto the right side of the bolt. The left side of the internal threaded ring is tightly fitted to the left side of the pressure ring. The left side of the pressure ring is tightly fitted to the right side wall of the U-shaped seat. Positioning pins are integrally formed at both the upper and lower ends of the left side of the pressure ring. Slider blocks are integrally formed at both the upper and lower ends of the inner side wall of the pressure ring. Positioning grooves are provided on both the upper and lower sides of the right side wall of the U-shaped seat. The positioning pins are inserted into the positioning grooves. Sliding grooves are provided on both the upper and lower ends of the threaded side wall of the bolt. The sliders are slidably installed in the sliding grooves.

[0006] Preferably, the right end of the slide is in the open state.

[0007] Preferably, the inner wall of the pressure ring does not contact the threaded side wall of the bolt.

[0008] Preferably, a rubber gasket is provided between the internal threaded ring and the pressure ring.

[0009] Preferably, the bolt has a smooth portion in the middle of the threaded shank sidewall.

[0010] Preferably, a corrugated pipe is fixedly connected to the top end of the slag inlet pipe.

[0011] Compared with the prior art, the beneficial effects of this patent are as follows: This patent has a connecting plate installed at the bottom of the spiral slag discharge machine body. The top left side of the base is hinged to the bottom left side of the connecting plate via a support rod. A motor with a turntable is installed on the top right side of the base. A swing arm is hinged to the front side of the turntable. The top of the swing arm is hinged to the bottom of the connecting plate via a hinge seat. After the spiral slag discharge machine body has been working for a period of time, the motor can drive the turntable to rotate, which in turn drives the connecting plate and the right side of the spiral slag discharge machine body to lift through the swing arm. This repeated vibration movement removes the slag accumulated at the bottom of the spiral slag discharge machine body shell, preventing long-term accumulation from causing blockage of the spiral shaft.

[0016] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0017] Please see Figure 1 , Figure 2 and Figure 3This patent provides a technical solution: an anti-clogging spiral slag discharge machine, including a spiral slag discharge machine body 1 and a base 5. The top of the shell of the spiral slag discharge machine body 1 is embedded with a slag inlet pipe 2. A connecting plate 3 is fixedly installed at the bottom of the shell of the spiral slag discharge machine body 1. Hinge seats 4 are fixedly installed at both the front and rear ends of the bottom left side of the connecting plate 3. Hinge seats 4 are fixedly installed at the bottom right side of the connecting plate 3. Support rods 6 are fixedly installed at both the front and rear ends of the top left side of the base 5. The top of the support rods 6 is hinged in the hinge seats 4. A motor 7 is fixedly installed on the top right side of the base 5. A turntable 8 is fixedly installed at the front end of the rotating shaft of the motor 7. A swing rod 9 is hinged to the lower side of the front side of the turntable 8. The top of the swing rod 9 is hinged in the hinge seats 4.

[0018] like Figure 1 As shown, the turntable 8 can be driven to rotate by the motor 7. The rotation of the turntable 8 will cause the swing arm 9 to swing left and right while moving up and down, thereby causing the connecting plate 3 and the right end of the spiral slag discharge machine body 1 to vibrate up and down, so as to displace the slag inside the bottom side of the shell of the spiral slag discharge machine body to the left.

[0019] The hinge 4 includes a U-shaped seat 10, a bolt 11, and a nut 12. The right end of the bolt 11 extends through the U-shaped seat 10 and the rocker arm 9 to the right side of the U-shaped seat 10. The nut 12 includes an internal threaded ring 13 and a pressure ring 14. The internal threaded ring 13 is screwed onto the right side of the bolt 11. The left side of the internal threaded ring 13 is tightly fitted to the left side of the pressure ring 14. The left side of the pressure ring 14 is tightly fitted to the right side wall of the U-shaped seat 10. The upper and lower ends of the left side of the pressure ring 14 are integrally formed with positioning pins 15. The upper and lower ends of the inner side wall of the pressure ring 14 are integrally formed with sliders 17. The upper and lower sides of the right side wall of the U-shaped seat 10 are provided with positioning grooves 16. The positioning pins 15 are inserted into the positioning grooves 16. The upper and lower ends of the threaded rod side wall of the bolt 11 are provided with sliding grooves 18. The sliders 17 are slidably installed in the sliding grooves 18.

[0020] Traditional hinges consist of a U-shaped seat, a bolt, and a nut. The bolt can pass through the U-shaped seat and the circular hole on the upper side of the rocker arm 9 and lock with the nut. However, as the rocker arm 9 swings, the friction between the circular hole and the side wall of the bolt can easily cause the bolt and nut to rotate slightly. Over time, the nut is prone to loosening and falling off.

[0021] With the positioning pin 15 inserted into the positioning groove 16, the pressure ring 14 will not rotate. The slider 17 on the inner side wall of the pressure ring 14 slides in the groove 18 (the slider 17 can only slide left and right in the groove 18 and will not move in other directions in the groove 18). Therefore, the threaded rod of the bolt 11 will not rotate. Since the threaded rod of the bolt 11 will not rotate, the internal threaded ring 13 that is screwed to it will not rotate with it.

[0022] Specifically, the right end of the slide 18 is in the open state.

[0023] The right end of the slide groove 18 is in the open state, which makes it easy to install the slider 17 into the slide groove 18 from the right end of the slide groove 18.

[0024] Specifically, the inner wall of the pressure ring 14 does not contact the threaded side wall of the bolt 11.

[0025] Specifically, a rubber gasket is provided between the internal threaded ring 13 and the pressure ring 14.

[0026] The rubber gasket prevents the internal threaded ring 13 from causing wear on the pressure ring 14.

[0027] Specifically, the bolt 11 has a smooth part 19 in the middle of the threaded rod sidewall.

[0028] The smooth part 19 is provided so that no thread is provided at the smooth part 19 position of the threaded rod of the bolt 11, so as to avoid the thread from hindering the relative sliding of the circular hole on the rocker arm 9.

[0029] Specifically, a corrugated pipe 20 is fixedly connected to the top end of the slag inlet pipe 2.

[0030] The top end of the corrugated pipe 20 is fixedly connected to the slag discharge port of the cold slag machine. The corrugated pipe 20 is designed to adapt to the up-and-down vibration of the spiral slag discharge machine body 1 based on its deformable characteristics.

[0031] Working principle: The slag cooler enters the shell of the spiral slag discharger through the slag discharge port. The rotating motor drives the spiral shaft inside the shell to rotate, and the spiral blades on the side wall of the spiral shaft drive the slag to move to the left and discharge it. The slag fragments inside the slag will accumulate at the bottom of the inner side wall of the shell. After a period of time, the motor 7 drives the turntable 8 to rotate. The rotation of the turntable 8 will drive the swing arm 9 to swing left and right and move up and down at the same time, which will cause the connecting plate 3 and the right end of the spiral slag discharger body 1 to vibrate up and down, so as to displace the slag fragments on the bottom side of the shell of the spiral slag discharger body to the left.

[0032] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent.
