Fluidized bed nozzle

Abstract

This invention discloses a fluidized bed nozzle, including a mounting plate with a mounting hole in the middle. A nozzle body is inserted through the middle of the mounting hole, and a guide cup is engaged at the top of the nozzle body. A flexible sealing cover is fixedly installed at the bottom of the guide cup surface, and a limiting seat is fixedly installed at the bottom of the nozzle body. This fluidized bed nozzle ensures the stable vertical movement of the nozzle body, guide cup, and outlet pipe by inserting the nozzle body through the mounting hole and by inserting two guide rods through two first guide holes and two second guide holes, respectively. During operation, the nozzle body, guide cup, and outlet pipe rise under wind resistance, thereby expelling hot air from the outlet and blowing up the material. When the machine stops, the nozzle body, guide cup, and outlet pipe return to their original positions under the gravity of gravity, so that the flexible sealing cover is in close contact with the mounting plate to achieve a sealing effect.

Description

Technical Field

[0001] This invention relates to the field of fluidized beds, specifically to a fluidized bed nozzle. Background Technology

[0002] Fluidized bed drying equipment for biomass operates by introducing hot air into nozzles through exhaust ducts to blow up the material (biomass, such as straw) for drying. Because fluidized bed is a horizontal vibrating drying device, a long conveying length is required to achieve the drying purpose, so a large number of nozzles are needed to supply hot air. However, the exhaust ducts of existing equipment on the market are fixed and welded. When the machine vibrates, heavier materials cannot be blown up, causing them to be hooked by the air guide bowl and fall below the air guide bowl, forming a blockage. They may even enter under the tube sheet, posing a fire hazard. During operation, due to factors such as power outages, the moisture content of the materials can cause the air guide bowl to become blocked and impossible to clean over time.

[0003] To address the aforementioned issues, a fluidized bed nozzle is proposed here. Summary of the Invention

[0004] The purpose of this invention is to provide a fluidized bed nozzle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fluidized bed nozzle, comprising a mounting plate, a mounting hole in the middle of the mounting plate, a nozzle body inserted through the middle of the mounting hole, an air guide cup engaged at the top of the nozzle body, a flexible sealing cover fixedly mounted on the bottom surface of the air guide cup, a limiting seat fixedly mounted at the bottom of the nozzle body, a connecting seat fixedly mounted at the bottom of the limiting seat, an air outlet pipe fixedly mounted in the middle of the connecting seat, the air outlet pipe communicating with the nozzle body, and first guide holes on both sides of the top of the limiting seat, with guide rods inserted through the interior of each of the two first guide holes, and both guide rods fixedly connected to the mounting plate.

[0006] The nozzle ensures the stable vertical movement of the nozzle body, air guide bowl, and air outlet pipe by interlacing the nozzle body with the mounting hole and the two guide rods with the two first guide holes and two second guide holes respectively. During operation, the nozzle body, air guide bowl, and air outlet pipe rise under wind resistance, thereby venting hot air from the air outlet and blowing the material up. The flexible sealing cover pushes the material outward after it falls, preventing it from entering the air guide bowl and avoiding fire hazards. When the machine stops, the nozzle body, air guide bowl, and air outlet pipe reset under the weight of the structure, ensuring that the flexible sealing cover is in close contact with the mounting plate to achieve a sealing effect.

[0007] Preferably, a connecting groove is provided at the connection between the air guide bowl and the nozzle body, and a connecting block is engaged inside the connecting groove. The connecting block is fixedly connected to the nozzle body, and the air guide bowl is fixed to the nozzle body by the limiting engagement of the two connecting blocks with the two connecting grooves respectively.

[0008] Preferably, two mounting slots are provided on the inner side of the connecting slot, and a limiting spring is fixedly installed inside each of the two mounting slots. A limiting groove is provided on one side of each of the two connecting blocks, and the two limiting springs are respectively engaged with the two limiting grooves. By using a large force to pull the air guide bowl upward, the two limiting springs are separated from the two limiting grooves, so as to facilitate the disassembly and maintenance of the air guide bowl.

[0009] Preferably, the nozzle body and the limiting seat are an integral structure, and the surface of the nozzle body is provided with a number of evenly distributed air outlets, and the limiting seat can play a limiting role.

[0010] Preferably, the top of the connecting seat has two second guide holes, which are respectively connected to two guide rods to ensure the stable up-and-down movement of the nozzle body, air guide bowl, and air outlet pipe.

[0011] Preferably, the mounting plate has fixing holes at all four corners of its top end to facilitate the installation of the overall structure.

[0012] Preferably, the flexible sealing cover is made of fluororubber material, which has the characteristics of high temperature resistance and flexibility, and plays a sealing role.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This nozzle ensures the stable vertical movement of the nozzle body, air guide bowl, and air outlet pipe by interlacing the nozzle body with the mounting hole and the two guide rods with the two first guide holes and the two second guide holes respectively. During operation, the nozzle body, air guide bowl, and air outlet pipe rise under wind resistance, and hot air is then discharged from the air outlet to blow the material up. The flexible sealing cover pushes the material outward after it falls, preventing it from entering the air guide bowl and avoiding fire hazards. When the machine stops, the nozzle body, air guide bowl, and air outlet pipe reset under the gravity of the structure, so that the flexible sealing cover is in close contact with the mounting plate to achieve a sealing effect.

[0015] 2. The air guide bowl is fixed to the nozzle body by engaging the two connecting blocks with the two connecting slots and the two limiting springs with the two limiting slots. By pulling the air guide bowl upward with a large force, the two limiting springs are separated from the two limiting slots, which facilitates the disassembly and maintenance of the air guide bowl.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Please see Figure 1-5 This invention provides a fluidized bed nozzle, including a mounting plate 1. A mounting hole 2 is formed in the center of the mounting plate 1, and a nozzle body 3 is inserted through the center of the mounting hole 2. A guide cup 4 is engaged at the top of the nozzle body 3, and a flexible sealing cover 6 is fixedly installed at the bottom of the surface of the guide cup 4. A limiting seat 7 is fixedly installed at the bottom of the nozzle body 3, and a connecting seat 16 is fixedly installed at the bottom of the limiting seat 7. An air outlet pipe 17 is fixedly installed in the center of the connecting seat 16, and the air outlet pipe 17 communicates with the nozzle body 3. First guide holes 8 are formed on both sides of the top of the limiting seat 7, and guide rods 9 are inserted through the two first guide holes 8. Both guide rods 9 are fixedly connected to the mounting plate 1. This nozzle... The main body 3 is interspersed with the mounting hole 2, and the two guide rods 9 are interspersed with the two first guide holes 8 and the two second guide holes 18 respectively, to ensure the stable up and down movement of the nozzle body 3, air guide bowl 4 and air outlet pipe 17. During operation, the nozzle body 3, air guide bowl 4 and air outlet pipe 17 rise under wind resistance, and then hot air is discharged from the air outlet 5 to blow the material up. The flexible sealing cover 6 can push the material outward after it falls, so that it does not enter the air guide bowl 4 and avoid fire hazards. When the machine stops, the nozzle body 3, air guide bowl 4 and air outlet pipe 17 reset under the action of gravity, so that the flexible sealing cover 6 is in close contact with the mounting plate 1 to achieve a sealing effect.

[0024] A connecting groove 10 is provided at the connection between the air guide bowl 4 and the nozzle body 3. A connecting block 11 is engaged inside the connecting groove 10. The connecting block 11 is fixedly connected to the nozzle body 3. The air guide bowl 4 is fixed to the nozzle body 3 by the two connecting blocks 11 engaging with the two connecting grooves 10 respectively. Two mounting grooves 12 are provided on the inner side of the connecting groove 10. A limiting spring piece 13 is fixedly provided inside the two mounting grooves 12. A limiting groove 14 is provided on one side of the two connecting blocks 11. The two limiting spring pieces 13 are engaged with the two limiting grooves 14 respectively. By using a large force to pull the air guide bowl 4 upward, the two limiting spring pieces 13 are separated from the two limiting grooves 14, so as to facilitate the disassembly and maintenance of the air guide bowl 4.

[0025] The nozzle body 3 and the limiting seat 7 are an integral structure. The surface of the nozzle body 3 has several evenly distributed air outlets 5. The limiting seat 7 can play a limiting role. The top of the connecting seat 16 has two second guide holes 18. The two second guide holes 18 are respectively connected to two guide rods 9 to ensure the stable up and down movement of the nozzle body 3, air guide bowl 4 and air outlet pipe 17. The four corners of the top of the mounting plate 1 are provided with fixing holes 15 to facilitate the installation of the overall structure. The flexible sealing cover 6 is made of fluororubber material. Fluororubber has the characteristics of high temperature resistance and flexibility, and plays a sealing role.

[0026] In this embodiment, the nozzle is used by interlacing the nozzle body 3 with the mounting hole 2 and the two guide rods 9 with the two first guide holes 8 and the two second guide holes 18 respectively. This ensures the stable vertical movement of the nozzle body 3, the air guide bowl 4, and the air outlet pipe 17. During operation, the nozzle body 3, the air guide bowl 4, and the air outlet pipe 17 rise under wind resistance, thereby drawing hot air out of the air outlet 5 and blowing the material up. The flexible sealing cover 6 pushes the material outward after it falls, preventing it from entering the air guide bowl 4 and avoiding damage. To prevent fire hazards, when the machine is shut down, the nozzle body 3, air guide bowl 4, and air outlet pipe 17 are reset under the weight of their components, allowing the flexible sealing cover 6 to come into close contact with the mounting plate 1 for sealing. The air guide bowl 4 is fixed to the nozzle body 3 by two connecting blocks 11 engaging with the two connecting slots 10 and two limiting springs 13 engaging with the two limiting grooves 14. By pulling the air guide bowl 4 upward with a large force, the two limiting springs 13 are separated from the two limiting grooves 14, making it easier to disassemble and maintain the air guide bowl 4.
