Description

Technical Field

[0001] This utility model belongs to the technical field of rotary dryers, specifically relating to a rotary dryer for processing lignite filtration loss reducers. Background Technology

[0002] Rotary dryers are used in the processing of lignite filtration loss reducers. The high efficiency of heat exchange and uniform drying provided by rotary dryers help to quickly remove moisture from lignite, ensuring its performance as a filtration loss reducer. At the same time, the adaptability and high efficiency of rotary dryers have led to their widespread application in this field.

[0003] Chinese Patent Publication No. CN 206989621 U discloses a rotary dryer for processing lignite filtration loss reducers, comprising a rotary tank for containing materials, an electric heating tube wound around the rotary tank in a circumferential direction along the outer periphery of the rotary tank, and a temperature measuring component for measuring the temperature of the rotary tank. The temperature measuring component and the electric heating tube are both connected to a control device, which can control the output power of the electric heating tube according to the temperature measured by the temperature measuring component.

[0004] However, the current rotary dryer equipment for processing lignite filtration loss reducers has the following problems: the attached material may cause blockage in some areas of the dryer's inner wall, which in turn affects the flow of material and may even cause the dryer to malfunction and cause production to stop. Therefore, we have proposed a rotary dryer equipment for processing lignite filtration loss reducers. Utility Model Content

[0005] The purpose of this invention is to provide a rotary dryer for processing lignite filtration loss reducers, which can solve the problem in related technologies where adhering materials may cause blockage in some areas of the dryer's inner wall, thereby affecting the flow of materials and even causing the dryer to malfunction and production to stop.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A rotary dryer for processing lignite filtration loss reducers includes a control box. A rotating device is mounted on the top of the control box. An arc-shaped clamp is fixedly connected to the output end of the rotating device. A housing is fixedly connected to the arc surface of the arc-shaped clamp. A feed pipe and a liquid inlet pipe are fixedly connected to the top of the housing. A discharge pipe is fixedly connected to the bottom of the housing. An anti-adhesion device is mounted on the top of the housing. The anti-adhesion device includes a motor. The bottom of the motor is fixedly connected to the top of the housing. A rotating shaft is fixedly connected to the output shaft of the motor. A reciprocating lead screw is fixedly connected to the bottom of the rotating shaft. A support plate is fixedly connected to the bottom of the reciprocating lead screw. A reciprocating threaded ring is threaded onto the outer wall of the reciprocating lead screw, allowing the reciprocating threaded ring to rotate and move up and down. A connecting rod is fixedly connected to the outer wall of the reciprocating threaded ring. A scraper is fixedly connected to the end of the connecting rod away from the reciprocating threaded ring.

[0008] A through-hole plate is fixedly connected to the top of the support plate, and several triangular blocks are fixedly connected to the side of the through-hole plate. The triangular blocks can allow the material inside the device to flow from the periphery to the central area.

[0009] The scraper contacts the inner wall of the outer casing, and the scraper can effectively remove the attached substances on the inner wall of the outer casing. The through-hole plate contacts the connecting rod, and the movement of the through-hole plate can drive the movement of the connecting rod.

[0010] The inner wall of the outer shell is provided with a striking device, which includes an elastic telescopic rod. The top of the elastic telescopic rod is fixedly connected to the inner wall of the outer shell, and the bottom of the elastic telescopic rod is fixedly connected to a support ring. The inner wall of the support ring is fixedly connected to an impact ring, and the bottom of the support ring is fixedly connected to a semi-circular extrusion block one. The top of the through-hole plate is fixedly connected to a semi-circular extrusion block two.

[0011] The through-hole plate is located on the movement trajectory of the impact ring, allowing the impact ring to fully impact the through-hole plate. The bottom surface of the impact ring is smaller than its top surface, which can effectively improve the impact effect.

[0012] The support ring has several holes, which make it easier for materials to flow in the equipment and reduce clogging problems. The first semi-circular extrusion block is located on the movement trajectory of the second semi-circular extrusion block. The first semi-circular extrusion block and the second semi-circular extrusion block are the same size, and the surfaces of the first semi-circular extrusion block and the second semi-circular extrusion block are smooth.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This invention, through the arrangement of a motor, rotating shaft, through-hole plate, reciprocating screw ring, connecting rod, support plate, scraper, reciprocating screw, and triangular block, enables the scraper to rotate and move up and down, effectively cleaning the deposits on the inner wall of the outer casing. This avoids the problem of excessive deposits on the inner wall affecting the working efficiency of the device after long-term operation. The rotation of the reciprocating screw drives the support plate to rotate, which in turn drives the through-hole plate to rotate. With the help of the triangular block, the rotation of the through-hole plate draws material from the periphery of the device towards the central area, ensuring sufficient material flow and improving the working efficiency of the device.

[0015] This invention utilizes an elastic telescopic rod, a support ring, an impact ring, a semi-circular extrusion block one, and a semi-circular extrusion block two. The support ring moves downwards rapidly, causing the impact ring to collide with the perforated plate. The perforated plate vibrates upon impact, and this vibration, via a connecting rod, causes the scraper to vibrate. This repeated action dislodging deposits from the perforated plate and scraper, preventing excessive accumulation of deposits and reducing the working efficiency of the perforated plate and scraper.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1-5 As shown, a rotary dryer for processing lignite filtration loss reducers includes a control box 1. A rotating device 2 is mounted on the top of the control box 1. An arc-shaped clamping plate 6 is fixedly connected to the output end of the rotating device 2. A housing 3 is fixedly connected to the arc surface of the arc-shaped clamping plate 6. A feed pipe 4 and a liquid inlet pipe 5 are fixedly connected to the top of the housing 3. A discharge pipe 7 is fixedly connected to the bottom of the housing 3. An anti-adhesion device 8 is mounted on the top of the housing 3. The anti-adhesion device 8 includes a motor 81. The bottom of 1 is fixedly connected to the top of the outer casing 3. The output shaft of the motor 81 is fixedly connected to the rotating shaft 82. The bottom of the rotating shaft 82 is fixedly connected to the reciprocating screw 88. The bottom of the reciprocating screw 88 is fixedly connected to the support plate 86. The outer wall of the reciprocating screw 88 is threadedly connected to the reciprocating thread ring 84. The reciprocating screw 88 can make the reciprocating thread ring 84 rotate and move up and down. The outer wall of the reciprocating thread ring 84 is fixedly connected to the connecting rod 85. The end of the connecting rod 85 away from the reciprocating thread ring 84 is fixedly connected to the scraper 87.

[0025] A through-hole plate 83 is fixedly connected to the top of the support plate 86, and several triangular blocks 89 are fixedly connected to the side of the through-hole plate 83. The triangular blocks 89 can make the material in the outer periphery of the device flow towards the central area.

[0026] The scraper 87 contacts the inner wall of the outer casing 3, and the scraper 87 can fully scrape off the deposits on the inner wall of the outer casing 3. The through-hole plate 83 contacts the connecting rod 85, and the movement of the through-hole plate 83 can drive the connecting rod 85 to move.

[0027] Based on the above structure, open the valves of the liquid inlet pipe 5 and the feed pipe 4 to allow lignite filtration reducer and wet coal powder or coal slurry to flow from the liquid inlet pipe 5 and the feed pipe 4 respectively. Close the valves of the liquid inlet pipe 5 and the feed pipe 4, start the rotating device 2, and then start the motor 81. The output shaft of the motor 81 causes the rotating shaft 82 to rotate. The rotation of the rotating shaft 82 drives the reciprocating screw 88 to rotate. The rotation of the reciprocating screw 88 drives the reciprocating thread ring 84 to rotate and move up and down. The rotation and up and down movement of the reciprocating thread ring 84 drives the connecting rod 85 to rotate and move up and down. The connecting rod 85 rotates... The moving and vertical movement of the scraper 87 causes it to rotate and move up and down, effectively cleaning the deposits on the inner wall of the outer casing 3. This avoids the problem of excessive deposits on the inner wall affecting the working efficiency of the device after long-term operation. The rotation of the reciprocating screw 88 causes the support plate 86 to rotate, which in turn causes the through-hole plate 83 to rotate. With the help of the triangular block 89, the rotation of the through-hole plate 83 causes the material in the outer periphery of the device to flow towards the central area, ensuring sufficient material flow and improving the working efficiency of the device.

[0028] like Figure 1-5 As shown, the inner wall of the outer shell 3 is provided with a striking device 9. The striking device 9 includes an elastic telescopic rod 91. The top of the elastic telescopic rod 91 is fixedly connected to the inner wall of the outer shell 3. The bottom of the elastic telescopic rod 91 is fixedly connected to a support ring 92. The inner wall of the support ring 92 is fixedly connected to an impact ring 93. The bottom of the support ring 92 is fixedly connected to a semi-circular extrusion block 94. The top of the through-hole plate 83 is fixedly connected to a semi-circular extrusion block 95.

[0029] The through-hole plate 83 is located on the movement trajectory of the impact ring 93, and the impact ring 93 can fully impact the through-hole plate 83. The bottom surface of the impact ring 93 is smaller than the top surface, which can effectively improve the impact effect.

[0030] The support ring 92 has several holes, which make it easier for materials to flow in the equipment and reduce clogging problems. The semi-circular extrusion block 1 94 is located on the movement trajectory of the semi-circular extrusion block 2 95. The semi-circular extrusion block 1 94 and the semi-circular extrusion block 2 95 are the same size, and the surfaces of the semi-circular extrusion block 1 94 and the semi-circular extrusion block 2 95 are smooth.

[0031] According to the above structure, the rotation of the through-hole plate 83 drives the movement of the semi-circular extrusion block 2 95. As the semi-circular extrusion block 2 95 moves, it touches the semi-circular extrusion block 1 94. The semi-circular extrusion block 1 94 drives the support ring 92 and the impact ring 93 to move away from the through-hole plate 83, and compresses the extension end of the elastic telescopic rod 91. When the semi-circular extrusion block 2 95 no longer touches the semi-circular extrusion block 1 94, the extension end of the elastic telescopic rod 91 will reset through its own elastic force. The reset of the extension end drives the support ring 92 to move downward quickly. The downward movement of the support ring 92 drives the impact ring 93 to collide with the through-hole plate 83. The through-hole plate 83 is impacted and vibrates. The vibration of the through-hole plate 83 drives the scraper 87 to vibrate through the connecting rod 85. This process repeats, thereby shaking off the deposits on the through-hole plate 83 and the scraper 87, preventing excessive accumulation of deposits on the through-hole plate 83 and the scraper 87, and reducing the working efficiency of the through-hole plate 83 and the scraper 87.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
