Description

Technical Field

[0001] This utility model relates to the field of preheater technology, and in particular to a self-cleaning module for preventing crusting in a gypsum acid preheater. Background Technology

[0002] In the gypsum-based acid production process, the preheater, as the core heat exchanger, plays a crucial role in exchanging heat between gypsum raw materials and high-temperature flue gas, providing raw materials with the required temperature for subsequent roasting processes. Its operational stability and heat exchange efficiency directly determine the overall production line's capacity, energy consumption, and environmental performance. Currently, the gypsum-based acid production preheaters widely used in the industry typically employ a cyclone separator as the core heat exchange unit. Gypsum powder is transported through fixed pipes, and gas-solid two-phase heat exchange is achieved through the swirling motion of high-temperature flue gas within the cyclone separator.

[0003] However, due to the inherent viscosity of gypsum powder and temperature fluctuations during heat exchange, the powder is prone to adhering to the inner wall of the cyclone separator and forming a crust. More importantly, most existing gypsum acid preheaters do not have a dedicated rapping mechanism, which makes the dust removal work difficult to overcome and has become the core pain point restricting the stable operation of the equipment. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a self-cleaning module for preventing skin formation in a gypsum acid preheater.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a self-cleaning module for preventing crusting in a gypsum acid preheater, comprising a cyclone and a fixed pipe. A feed hopper is fixedly installed on the top outer wall of the fixed pipe. A drive motor is fixedly installed at the end of the fixed pipe away from the cyclone. A spiral conveying rod is fixedly installed at the output end of the drive motor. An air inlet pipe is fixedly installed at the bottom of the cyclone. A discharge pipe is fixedly installed at the top of the cyclone. A vibrating mechanism is symmetrically installed on the outer wall of the cyclone. The vibrating mechanism includes an L-plate. A reserved hole is uniformly opened through one side of the L-plate. A sliding rod is slidably connected inside the reserved hole. A vibrating block is fixedly installed at one end of the sliding rod. A pull handle is fixedly installed at the end of the sliding rod away from the vibrating block. A spring is sleeved on the outer wall of the sliding rod.

[0006] Preferably, the fixing pipe is located on the outer wall of the cyclone, and the fixing pipe is fixedly connected to the cyclone.

[0007] Preferably, there are two sets of L-plates, and the two sets of L-plates are located on the outer wall of the cyclone, and the two sets of L-plates are fixedly connected to the cyclone.

[0008] Preferably, one end of the spring is fixedly connected to the vibrating block, and the other end of the spring is fixedly connected to the L-plate.

[0009] Preferably, a shaft is symmetrically rotatably connected inside the top of the cyclone, and a dispersing rod is uniformly and symmetrically fixedly installed on the outer wall of the shaft. A gear is fixedly installed at the top of the shaft, an L-plate is fixedly installed at the top of the cyclone, a drive motor is fixedly installed at the top of the L-plate, and a gear is fixedly installed at the output end of the drive motor.

[0010] Preferably, there are two sets of gears, and the two sets of gears mesh with each other.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the symmetrically arranged rapping mechanism on the outer wall of the cyclone separator achieves active dust removal through the cooperation of the handle, slide bar, spring, and rapping block. When the operator pulls the handle to compress the spring and then releases it, the elastic force generated by the spring's return can push the rapping block to violently impact the outer wall of the cyclone separator. The vibration wave is transmitted along the separator wall to the inner wall, which can effectively peel off the attached powder and initial skin. Moreover, the impact points of the two sets of rapping mechanisms cover the key areas of the cyclone separator, avoiding the problem of many blind spots in the dust removal of traditional equipment, ensuring that the cyclone separator maintains a good heat exchange state for a long time, and reducing downtime losses caused by skin blockage.

[0013] 2. In this utility model, by starting the second drive motor, it drives the second gear to rotate. Since the two sets of gears one and two mesh with each other, the rotation of the second gear will synchronously drive the two sets of gears one and the shaft fixed thereto to rotate. The dispersing rods evenly and symmetrically installed on the outer wall of the shaft will rotate at high speed. The rotation of the dispersing rods can quickly disperse the gypsum powder entering the cyclone, preventing the powder from agglomerating into large pieces of material. Attached Figure Description

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a self-cleaning module for preventing crusting in a gypsum acid preheater, comprising a cyclone 1 and a fixed pipe 2. A feed hopper 3 is fixedly installed on the top outer wall of the fixed pipe 2. A drive motor 4 is fixedly installed at the end of the fixed pipe 2 away from the cyclone 1. A spiral conveying rod 5 is fixedly installed at the output end of the drive motor 4. An air inlet pipe 6 is fixedly installed at the bottom of the cyclone 1. A discharge pipe 7 is fixedly installed at the top of the cyclone 1. A vibrating mechanism 8 is symmetrically installed on the outer wall of the cyclone 1. The vibrating mechanism 8 includes an L-plate 801. A reserved hole 802 is uniformly opened through one side of the L-plate 801. The internal sliding connection of 02 includes a slide rod 803. One end of the slide rod 803 is fixedly installed with a vibrating block 804, and the end of the slide rod 803 away from the vibrating block 804 is fixedly installed with a handle 805. A spring 806 is sleeved on the outer wall of the slide rod 803. The fixing tube 2 is located on the outer wall of the cyclone 1 and is fixedly connected to the cyclone 1. There are two sets of L-plates 801. The two sets of L-plates 801 are located on the outer wall of the cyclone 1 and are fixedly connected to the cyclone 1. One end of the spring 806 is fixedly connected to the vibrating block 804, and the other end of the spring 806 is fixedly connected to the L-plate 801.

[0022] In this embodiment, the active dust removal is achieved through the symmetrically arranged rapping mechanisms 8 on the outer wall of the cyclone 1, which work together with the pull handle 805, slide rod 803, spring 806, and rapping block 804. When the operator pulls the pull handle 805 to compress the spring 806 and then releases it, the elastic force generated by the spring 806 returning to its original position can push the rapping block 804 to violently impact the outer wall of the cyclone 1. The vibration wave is transmitted along the cylinder wall to the inner wall, which can effectively peel off the attached powder and initial skin. Moreover, the impact points of the two sets of rapping mechanisms 8 cover the key areas of the cyclone 1, avoiding the problem of many blind spots in the dust removal of traditional equipment, ensuring that the cyclone 1 maintains a good heat exchange state for a long time, and reducing downtime losses caused by skin blockage.

[0023] Example 2: As Figure 3 As shown, a shaft 9 is symmetrically rotatably connected inside the top of the cyclone 1. A dispersing rod 10 is uniformly and symmetrically fixed on the outer wall of the shaft 9. A gear 11 is fixedly installed at the top of the shaft 9. An L-plate 12 is fixedly installed at the top of the cyclone 1. A drive motor 13 is fixedly installed at the top of the L-plate 12. A gear 14 is fixedly installed at the output end of the drive motor 13. There are two sets of gears 11, and the two sets of gears 11 and gears 14 mesh with each other.

[0024] In this embodiment, by starting the drive motor 13, the gear 14 is driven to rotate. Since the two sets of gears 11 and gear 14 mesh with each other, the rotation of gear 14 will synchronously drive the two sets of gears 11 and the shaft 9 fixed thereto to rotate. The dispersing rods 10, which are uniformly and symmetrically installed on the outer wall of the shaft 9, will rotate at high speed. The rotation of the dispersing rods 10 can quickly disperse the gypsum powder entering the cyclone 1, and prevent the powder from agglomerating into large pieces of material.

[0025] The working principle of this embodiment is as follows: After the equipment is started, the gypsum raw material is first fed into the feed hopper 3 on the top outer wall of the fixed pipe 2. At this time, the drive motor 4 at the end of the fixed pipe 2 away from the cyclone 1 starts synchronously. The output end of the drive motor 4 drives the spiral conveying rod 5 fixedly connected to it to rotate inside the fixed pipe 2. Using the thrust generated by the spiral helix angle of the spiral blades, the gypsum powder falling into the feed hopper 3 is smoothly conveyed to the inside of the cyclone 1 along the length of the fixed pipe 2. Compared with the problem of powder accumulation due to natural flow in traditional equipment, the continuous rotation of the spiral conveying rod 5 can not only avoid the powder from clogging in the fixed pipe 2, but also reduce the adhesion of powder to the inner wall of the fixed pipe 2 through the slight friction between the blades and the pipe wall, thus reducing the risk of skin formation in the initial stage of the conveying process. When the gypsum powder enters the cyclone 1, the high-temperature flue gas is continuously introduced through the air inlet pipe 6 at the bottom of the cyclone 1. The high-temperature flue gas forms a high-speed swirling motion inside the cyclone 1, and forms a full gas-solid two-phase contact with the gypsum powder transported from the fixed pipe 2, realizing heat exchange. The heat of the high-temperature flue gas is transferred to the gypsum powder, causing the powder temperature to rise rapidly to meet the requirements of the subsequent calcination process. After preheating, the powder is finally discharged through the discharge pipe 7 at the top of the cyclone 1. During this process, the shafts 9 and dispersing rods 10, which are symmetrically arranged inside the top of the cyclone 1, operate synchronously. By starting the drive motor 13, the second gear 14 is driven to rotate. Since the two sets of gears 11 and gear 14 mesh with each other, the rotation of gear 14 will synchronously drive the two sets of gears 11 and the shafts 9 fixed to them to rotate. The dispersing rods 10, which are evenly and symmetrically installed on the outer wall of the shaft 9, rotate at high speed. The rotation of the dispersing rods 10 can quickly disperse the gypsum powder entering the cyclone 1, preventing the powder from agglomerating into large pieces of material. When it is necessary to clean the powder or initial skin adhering to the inner wall of the cyclone 1, the operator pulls the handle 805, causing the slide rod 803 to slide outward along the reserved hole 802 on the L plate 801. At this time, the spring 806 sleeved on the outer wall of the slide rod 803 is compressed. When the handle 805 is pulled to its maximum stroke, the operator releases the handle 805, and the compressed spring 806 quickly returns to its original position. The resulting elastic force pushes the slide rod 803 and the vibrating block 804 to move rapidly toward the cyclone 1. The vibrating block 804 violently impacts the outer wall of the cyclone 1. The vibration wave generated by the impact is transmitted along the outer wall of the cyclone 1 to the inner wall, effectively peeling off the powder and initial skin adhering to the inner wall. The vibration wave can break the adhesion between the skin and the inner wall, causing the skin to fall off and be discharged from the discharge pipe 7 along with the airflow or powder, thus achieving self-cleaning.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
