Description

Technical Field

[0001] The utility model relates to the technical field of flame deflectors, in particular to a flame direct-split flow deflector. Background Art

[0002] Modern kilns for producing advanced structural ceramics must inevitably evolve from electric heating rod radiation kilns to natural gas flame swirl kilns. This is because electric heating rod radiation creates an unchangeable temperature gradient, commonly known as a "temperature differential," depending on the distance between the product and the rod. This gradient, typically exceeding 20°C, directly leads to inconsistent crystal morphology in the ceramic product, significantly altering its physical properties. This can lead to substandard hardness, toughness, flexural strength, and compressive strength. Conventional testing has shown that kiln temperatures are higher at the top and lower at the bottom, and higher at the edges and lower at the bottom, conforming to the principle of higher temperatures near the radiation point and lower temperatures farther away.

[0003] Advanced natural gas kilns are completely different. They use jet combustion. Although the nozzle is also installed on the inside of the kiln wall, its gas nozzle can spray farther. More importantly, the flame temperature rotates from high to low. The maximum measured temperature difference does not exceed 5°C, and generally can reach below 3°C, ensuring excellent quality of all products.

[0004] However, in practice, a small number of products in each kiln cracked and were scrapped. The reason was that the flame of the gas nozzle was long and had impact force, which caused the products to crack at the impacted position.

[0005] For this purpose, a flame direct-flow diverter is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0007] Specifically, the technical problem to be solved by the present invention is to provide a flame direct-injection diverter to solve the technical problem that a small number of products in each natural gas kiln of the current kiln are cracked and scrapped. The reason is that the flame of the gas nozzle is long and has impact force, which causes the products at the impacted position to crack.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0009] A flame directing diverter comprises a diverter seat and a semicircular ball, wherein the semicircular ball is rotatably mounted on the arc surface of the diverter seat, and a plurality of diverter strips are mounted on the arc surface of the semicircular ball at equal intervals, and a flame flow cavity is formed between adjacent diverter strips;

[0010] A gear is installed on the rotating end of the semicircular ball, a pneumatic lifting source is fixed to the end of the diverter seat away from the semicircular ball, and a rack meshing with the gear is installed on the movable end of the pneumatic lifting source.

[0011] As an improved technical solution, a first refractory layer is installed on the outer wall surface of the diverter seat close to the semicircular sphere, and a second refractory layer is installed on the outer wall surface of the semicircular sphere.

[0012] As an improved technical solution, an axial hole is opened on the diverter seat and is coaxial with the semicircular ball. A rotating shaft is rotatably installed inside the axial hole, and the semicircular ball is fixed at one end of the rotating shaft, and the gear is fixed at the other end of the rotating shaft.

[0013] As an improved technical solution, the pneumatic lifting source includes a sleeve fixed on the diverter seat, a piston head is movably provided in the inner cavity of the sleeve, a coaxial lifting rod is installed at the end of the piston head close to the rack, and the rack is arranged at the top of the lifting rod, the outer wall surface of the lifting rod is located on the top of the piston head and a spring is sleeved, and a coaxial inlet and outlet are opened at the end of the sleeve away from the rack.

[0014] As an improved technical solution, two ring grooves are provided on the peripheral surface of the piston head, and sealing rings are installed inside the ring grooves.

[0015] As an improved technical solution, a sliding hole for the lifting rod to pass through is opened on the top of the sleeve, a mounting block is fixed to the end of the lifting rod away from the piston head, and the rack is fixed on the mounting block.

[0016] As an improved technical solution, a threaded pipe coaxial with the inlet and outlet is welded to one end of the sleeve close to the inlet and outlet, and the threaded pipe is connected to the interior of the sleeve through the inlet and outlet.

[0017] After adopting the above technical solution, the beneficial effects of the utility model are:

[0018] 1. In the utility model, the flame is sprayed toward the direction of the semicircular ball, and the flame is slowed down and smoothly diverted to the upper space through the diverter seat and the semicircular ball, flows to the other side of the kiln and is guided downward in the normal direction of the product foot, preventing the flame from directly impacting the product, thereby avoiding the problem of product cracking and scrapping caused by the nozzle flame, and improving economic benefits.

[0019] 2. In the present invention, when the gas source is intermittently delivered to the inside of the pneumatic lifting source, the rack is prompted to move up and down reciprocatingly. Under the meshing transmission action of the rack and the gear, the rotating shaft drives the semicircular ball to rotate, prompting the diverter strip to rotate, which will drive the flame located in the flame flow cavity to rotate, thereby driving the flame to form a rotating flow in the kiln, further equalizing the temperature in the kiln.

[0030] like Figures 1 to 3 As shown together, this embodiment provides a flame direct-injection diverter, which includes a diverter seat 1 and a semicircular ball 2. The semicircular ball 2 is rotatably mounted on the arc surface of the diverter seat 1. The flame is ejected in the direction of the semicircular ball 2. The flame is decelerated and smoothly diverted to the upper end space under the guidance of the diverter seat 1 and the semicircular ball 2. It flows to the other side of the kiln and is then directed downward in the normal direction of the product foot flow, preventing the flame from directly impacting the product, thereby avoiding the problem of product cracking and scrapping caused by the nozzle flame, and improving economic efficiency. A plurality of diverter strips 25 are installed at equal intervals on the arc surface of the semicircular ball 2, and a flame flow cavity is formed between adjacent diverter strips 25.

[0031] A gear 23 is installed at the rotating end of the semicircular ball 2 , and a pneumatic lifting source 3 is fixed to the end of the diverter seat 1 away from the semicircular ball 2 . A rack 24 meshing with the gear 23 is installed at the movable end of the pneumatic lifting source 3 .

[0032] like Figure 1 As shown, in this embodiment, a refractory layer 11 is installed on the outer wall surface of the diverter seat 1 close to the semicircular ball 2, and a refractory layer 2 21 is installed on the outer wall surface of the semicircular ball 2. The setting of the refractory layer 11 and the refractory layer 2 21 improves the heat resistance of the diverter seat 1 and the semicircular ball 2, and extends the service life of the diverter seat 1 and the semicircular ball 2.

[0033] like Figures 1 to 2As shown together, in this embodiment, an axial hole 12 is opened on the diverter seat 1 and is coaxial with the semicircular ball 2. A rotating shaft 22 is rotatably installed inside the axial hole 12, and the semicircular ball 2 is fixed at one end of the rotating shaft 22, and the gear 23 is fixed at the other end of the rotating shaft 22.

[0034] like Figures 1 to 3 As shown together, in this embodiment, the pneumatic lifting source 3 includes a sleeve 31 fixed on the diverter seat 1, and a piston head 35 is movably provided in the inner cavity of the sleeve 31. A coaxial lifting rod 32 is installed at one end of the piston head 35 close to the rack 24, and the rack 24 is arranged at the top of the lifting rod 32. A spring 33 is sleeved on the outer wall surface of the lifting rod 32 and located on the top of the piston head 35. A coaxial inlet and outlet 38 is opened at the end of the sleeve 31 away from the rack 24.

[0035] like Figures 2 to 3 As shown, in this embodiment, two ring grooves are formed on the peripheral surface of the piston head 35 , and sealing rings 36 are installed inside the ring grooves.

[0036] like Figure 2 As shown, in this embodiment, a sliding hole is opened at the top of the sleeve 31 for the lifting rod 32 to pass through, and a mounting block 34 is fixed to the end of the lifting rod 32 away from the piston head 35, and the rack 24 is fixed on the mounting block 34.

[0037] When the gas source is intermittently delivered to the inside of the pneumatic lifting source 3, the rack 24 is prompted to move up and down reciprocatingly. Under the meshing transmission action of the rack 24 and the gear 23, the rotating shaft 22 drives the semicircular ball 2 to rotate, prompting the diverter strip 25 to rotate, which will drive the flame located in the flame flow cavity to rotate, thereby driving the flame to form a rotating flow in the kiln, further equalizing the temperature in the kiln.

[0038] like Figures 2 to 3 As shown together, in this embodiment, a threaded pipe 37 coaxial with the inlet and outlet 38 is welded to one end of the sleeve 31 close to the inlet and outlet 38, and the threaded pipe 37 is connected to the interior of the sleeve 31 through the inlet and outlet 38, and the threaded pipe 37 is connected to an external gas source.

[0039] When in use, the flame is ejected in the direction of the semicircular ball 2, and the flame is decelerated and smoothly diverted to the upper space through the diverter seat 1 and the semicircular ball 2, flows to the other side of the kiln and then downwards to the normal direction of the product foot.

[0040] The threaded pipe 37 is connected to an external air source through a pipeline, and the air source can be a high-pressure fan. When the flame is sprayed toward the semicircular ball 2, the external air source intermittently transports gas to the inside of the pneumatic lifting source 3. When the gas is transported to the inside of the pneumatic lifting source 3, the airflow is transported to the inside of the sleeve 31 through the threaded pipe 37 and the inlet and outlet 38. The airflow will push the piston head 35 to move toward the mounting block 34, so that the lifting rod 32 drives the rack 24 to move toward the direction of the rotating shaft 22. At this time, the piston head 35 will also compress the spring 33. When the rack 24 moves upward, due to the meshing transmission action of the rack 24 and the gear 23, the rotating shaft 22 will be driven to rotate. When the airflow is not transported to the inside of the sleeve 31, under the elastic reset action of the spring 33, the piston head 35 is reset and drives the rack 24 to move downward, prompting the diverter strip 25 to rotate.

[0041] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
