[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] A preferred embodiment of the present invention, a high-speed permanent magnet synchronous motor for purging, will be described in detail below, such as... Figures 3-7 As shown, a high-speed permanent magnet synchronous motor for purging includes a body 1. An external cooling fan 2 is sleeved around the right side of the body 1. A mounting base 3 is fixedly installed at the bottom of the external cooling fan 2. A blowing cylinder 4 is fixedly installed at the left end of the body 1. A fan blade is rotatably connected inside the blowing cylinder 4. The fan blade is connected to the drive shaft of the body 1, thereby driving the fan blade to rotate and blow air to the left inside the blowing cylinder 4.

[0033] A suction pipe 5 is fixedly installed on the outer periphery of the blowing tube 4. The suction pipe 5 adopts a "U" shape design, and both ends of the opening face vertically upward. A protective cover 9 is fitted on the top opening of the suction pipe 5 to protect the suction pipe 5 and prevent large particles of slag from falling into the inside of the suction pipe 5. A dustproof component 6 is provided on the top of the suction pipe 5. An air jet plate 7 is connected to the left side of the blowing tube 4 for limiting rolling. A swing component 8 is provided between the air jet plate 7 and the mounting base 3.

[0034] In use, the external cooling fan 2 and the mounting base 3 are used to install the machine body 1 in the designated purging area. The machine body 1 drives the rotation of the fan blades inside the blower 4 to blow air to the left. The suction pipe 5 allows the gas to enter the blower 4, thereby achieving continuous purging. The gas blown to the left from the blower 4 is blown out obliquely downward through the jet plate 7, thereby purging the slag adhering to the conveyor belt.

[0035] The dustproof component 6 is designed to seal the top opening of the suction pipe 5 when the blowing stops, preventing dust from accumulating and entering the blowing cylinder 4, thus ensuring the normal operation of slag blowing. When facing a wider conveyor belt, the swing component 8 can drive the jet plate 7 to swing up and down, thereby achieving the swing blowing of the jet plate 7 and ensuring the comprehensive blowing of slag on the conveyor belt.

[0036] Furthermore, such as Figure 2 As shown, the dustproof component 6 includes a disc cover 61. The disc cover 61 is fixedly installed on the outer periphery of the top of the suction pipe 5. The disc cover 61 is rotatably connected to a turntable 62. Filter plates 63 are symmetrically placed on both sides of the top of the turntable 62. The filter plates 63 are offset from the top opening of the suction pipe 5. During operation, the filter plates 63 can rotate to be aligned with the top opening of the suction pipe 5.

[0037] A needle tube 64 is fixedly connected to the center of the disc cover 61. The needle tube 64 extends downward to communicate with the inside of the blow tube 4. A round hole is opened at the center of the top of the needle tube 64. A piston column 65 is slidably connected inside the needle tube 64. A spiral rod 66 is fixedly connected at the center between the piston columns 65. The spiral rod 66 passes through the turntable 62 from top to bottom. A groove that matches the spiral rod 66 is opened in the middle of the turntable 62. Therefore, when the spiral rod 66 moves up and down, it can drive the turntable 62 to rotate. A spring 67 is fixedly connected between the top of the piston column 65 and the inner wall of the needle tube 64.

[0038] The outer sides of the disc cover 61 are symmetrically fitted with fastening plates 68. The fastening plates 68 are located above the filter plate 63. The filter plate 63 can be cleaned and replaced by opening the fastening plates 68.

[0039] The principle of dust prevention for the blower 4 by the dustproof component 6 is as follows:

[0040] During purging, when the air inside the blower 4 is blown to the left, a negative pressure is generated inside the blower 4 and below the piston 65 inside the needle tube 64. Through the round hole at the center of the top of the needle tube 64, the piston 65 and the spiral rod 66 are pushed downward by the air pressure to move the tension spring 67 downward. During the downward movement of the spiral rod 66, the cooperation between the spiral rod 66 and the turntable 62 can drive the turntable 62 to rotate, thereby causing the turntable 62 to align the filter plates 63 on both sides with the two openings at the top of the suction tube 5, thus not affecting the normal air intake of the suction tube 5.

[0041] When purging stops, the negative pressure inside the blower 4 is no longer generated. The piston rod 65 and the screw rod 66 will move upward under the restoring force of the spring 67. By utilizing the cooperation between the screw rod 66 and the turntable 62, the turntable 62 can rotate, thereby causing the filter plates 63 on both sides to be misaligned with the two openings at the top of the suction pipe 5. This allows the turntable 62 to seal the two openings at the top of the suction pipe 5, preventing dust from entering the inside of the blower 4 during the slag conveying process after purging stops. At the same time, the filter plates 63 are hidden inside the disc cover 61, which also prevents dust from accumulating on the filter plates 63.

[0042] When purging stops, the filter plate 63 can be cleaned and replaced by opening the snap-fit ​​plate 68.

[0043] Furthermore, such as Figure 4 , Figures 8-9 , ​ As shown, the swing assembly 8 includes a base plate 81. The bottom of the jet plate 7 is hinged to the base plate 81. A spring 82 is fixedly connected between the top left side of the base plate 81 and the inner top wall of the jet plate 7. There are two springs 82, which are symmetrically distributed at the top left side of the base plate 81. The mounting base 3 is internally rotatably connected to a turntable 83. An eccentric column 84 is eccentrically fixedly installed at the top of the turntable 83. The mounting base 3 is internally slidably connected to a sliding groove strip 85. A telescopic rod 86 is fixedly connected to the center of the left end of the sliding groove strip 85. The sliding groove strip 85 is located above the turntable 83, and the eccentric column 84 extends upward to the inner side of the sliding groove strip 85. Therefore, when the turntable 83 rotates, it can drive the sliding groove strip 85 and the telescopic rod 86 to move back and forth.

[0044] A transmission rod 87 is hinged between the left side of the telescopic rod 86 and the bottom of the middle part of the base plate 81. A motor 88 is fixedly installed at the top of the mounting base 3, and the motor 88 is connected to the turntable 83 for driving the turntable 83 to rotate.

[0045] The connection between the blower 4 and the jet plate 7 adopts a ball joint hinge design. The blower 4 and the jet plate 7 are connected, and friction grooves 41 are provided on the top of the ball joint between the blower 4 and the jet plate 7. Therefore, when the jet plate 7 flips upward on the left, the friction force of the jet plate 7 can be increased by the increased contact with the friction grooves 41.

[0046] The principle by which the jet plate 7 is driven to swing by the swing assembly 8 is as follows:

[0047] When oscillating blowing is required, the motor 88 is started, which drives the turntable 83 to rotate. During the rotation of the turntable 83, the eccentric column 84 installed eccentrically at the top of the turntable 83 cooperates with the slide bar 85 to drive the slide bar 85 and the telescopic rod 86 to move back and forth. During the reciprocating movement of the telescopic rod 86, the base plate 81 and the jet plate 7 can be driven to oscillate up and down through the transmission rod 87, thereby realizing oscillating blowing to adapt to the wider conveyor belt.

[0048] It should be noted that, through the cooperation of spring 82 between the top left side of the base plate 81 and the inner top wall of the jet plate 7, and the design of friction grooves 41 at the top of the ball joint between the blower 4 and the jet plate 7, the friction force on the jet plate 7 gradually increases as the left side of the jet plate 7 flips upward. As a result, the base plate 81 is pushed to compress spring 82 more during the upward flipping process. Therefore, the distance between the left side of the base plate 81 and the inner top wall of the jet plate 7 gradually decreases, resulting in a gradual decrease in the gas passage area. Thus, as the jet plate 7 flips upward, the gas flow velocity ejected obliquely downward by the jet plate 7 gradually increases due to the gradually decreasing gas passage area. This allows for better blowing of distant slag while maintaining the initial purging range, thereby improving the slag purging removal effect.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
