[0051] Embodiment

[0052] The present invention will be further described below in conjunction with the accompanying drawings.

[0053] As Figure 1 、 Figure 3 shown, a combustion equipment for a calcination furnace of a lithium-ion battery material provided in this embodiment is installed on the calcination furnace 1 and includes:

[0054] An installation housing 20, the installation housing 20 is installed on the surface of the calcination furnace 1, and a front cover 21 is installed at the end of the installation housing 20 away from the calcination furnace 1;

[0055] A gas heating component 22, the gas heating component 22 is installed on the installation housing 20, the gas heating component 22 includes a gas pipe 23 and an ignition rod 24, the gas pipe 23 extends into the calcination furnace 1, and the ignition rod 24 is located inside the gas pipe 23;

[0056] Double-layer SIC refractory sleeve 25, the double-layer refractory sleeve 25 includes an SIC outer sleeve 32 and an SIC inner sleeve 33, the SIC outer sleeve 32 is hermetically sleeved outside the SIC inner sleeve 33, the SIC outer sleeve 32 is installed at the end of the installation housing 20 away from the front cover 21 through an outer sleeve fixing bracket 31, and the SIC inner sleeve 33 extends into the installation housing 20.

[0057] The working principle and beneficial effects of the above technical solution are as follows:

[0058] The present invention discloses a combustion equipment for a calcination furnace of lithium-ion battery materials, which is detachably installed on the calcination furnace 1. Gas is introduced into the gas pipe 23, and the ignition rod 24 works to ignite the gas. The gas burns inside the double-layer SIC refractory sleeve 25 composed of the SIC outer sleeve 32 and the SIC inner sleeve 33 to supply heat to the calcination furnace 1. The present invention provides a combustion equipment for a calcination furnace of lithium-ion battery materials, which uses gas combustion to provide heat to replace the use of resistance wires or silicon carbide rods as heating elements, realizing energy conservation and consumption reduction of electricity to meet the current market environment.

[0059] As Figure 2 、 Figure 4 shown, in one embodiment, the gas heating assembly 22 further includes:

[0060] An ignition electrode 26, the ignition electrode 26 is installed on the front cover 21, and the ignition electrode 26 is connected to the ignition rod 24;

[0061] A flame detector 27, the flame detector 27 is installed on the front cover 21, and the flame detector 27 is used to detect the flame combustion information inside the installation housing 20.

[0062] The working principle of the above technical solution is:

[0063] The ignition electrode 26 is connected to the ignition rod 24 and is used to provide an ignition effect for the gas in the gas pipe 23 to the ignition rod 24. The flame detector 27 is used to detect the flame combustion information inside the combustion equipment.

[0064] In one embodiment, the outer sleeve fixing bracket 31 is detachably installed on the surface of the calcination furnace through blackened bolts.

[0065] In one embodiment, an independent smoke outlet chamber 37 and an air inlet chamber 38 are formed in the installation housing 20. The air inlet chamber 38 is formed around the smoke outlet chamber 37. The air inlet chamber 38 is arranged close to the front cover 21. The end of the smoke outlet chamber 37 far from the air inlet chamber 38 is open and communicates with the SIC outer sleeve 32. The SIC inner sleeve 33 passes through the smoke outlet chamber 37 and communicates with the air inlet chamber 38. A smoke outlet passage 48 communicating with the smoke outlet chamber 37 is formed between the SIC outer sleeve 32 and the SIC inner sleeve 33.

[0066] The working principle and beneficial effects of the above technical solution are as follows:

[0067] An independent smoke outlet chamber 37 and an air inlet chamber 38 are formed in the installation housing 20. Combustion-supporting air is sent into the air inlet chamber 38 and then into the SIC inner sleeve 33 inserted into the air inlet chamber 38, so as to provide combustion support for the combustion of the gas located in the SIC inner sleeve 33. The heat of combustion is radiated to the heating product through the SIC inner sleeve 33 and the SIC outer sleeve 32. The combustion flue gas is sent into the smoke outlet chamber 37 through the smoke outlet passage 48 formed between the SIC outer sleeve 32 and the SIC inner sleeve 33. Since the smoke outlet chamber 37 and the air inlet chamber 38 are independent of each other, the combustion-supporting air and the flue gas are separated. The waste gases (CO, CO2, SO2, H2O, SO2, NOX) generated during the combustion process are completely isolated from the atmosphere of the kiln channel.

[0068] As Figure 4 shown, in one embodiment, the gas heating assembly 22 further includes:

[0069] A gas inlet 28, which is formed on the front cover 21 and is used to supply gas to the gas pipe 23;

[0070] A combustion-supporting air seat 29, which is installed at the top of the installation housing 20. A smoke outlet 39 runs vertically through the combustion-supporting air seat 29. The smoke outlet 39 passes through the top of the installation housing 20 and communicates with the smoke outlet chamber 37. An annular combustion-supporting air chamber 30 is arranged around the smoke outlet 39 in the combustion-supporting air seat 29. An air inlet 36 communicating with the annular combustion-supporting air chamber 30 is formed on the side end of the combustion-supporting air inlet seat 29. An air inlet passage 47 passing through the top of the installation housing 20 and communicating with the air inlet chamber 38 is formed at the bottom of the annular combustion-supporting air chamber 30 far from the air inlet 36.

[0071] The working principle and beneficial effects of the above technical solution are as follows:

[0072] The combustion-supporting air enters the annular combustion-supporting air chamber 30 from the air inlet 36, and enters the air inlet chamber 38 and the SIC inner sleeve 33 inserted into the air inlet chamber 38 through the air inlet channel 47, so as to provide combustion support for the combustion of the gas located in the SIC inner sleeve 33. The heat of combustion is radiated to the heated product through the SIC inner sleeve 33 and the SIC outer sleeve 32. The combustion flue gas enters the smoke outlet chamber 37 from the smoke outlet channel 48 formed between the SIC outer sleeve 32 and the SIC inner sleeve 33, and is sent out from the smoke outlet 39. In this way, the combustion-supporting air and the flue gas are separated, and the waste gases (CO, CO2, SO2, H2O, SO2, NOX) generated during the combustion process are completely isolated from the atmosphere of the kiln channel.

[0073] As Figure 2 shown, in one embodiment, the gas heating assembly 22 further includes:

[0074] A viewing hole 34 is opened on the front cover 21.

[0075] The beneficial effects of the above technical solution are:

[0076] The viewing hole 34 is used to observe the flame combustion condition.

[0077] As Figure 5 shown, in one example, a shock-absorbing assembly is installed at the position of the top inside the annular combustion-supporting air chamber 30 far from the air inlet 36. The shock-absorbing assembly is embedded and installed on the combustion-supporting air seat 29 and is arranged opposite to the air inlet channel 47.

[0078] The working principle and beneficial effects of the above technical solution are:

[0079] The outside air is sent into the annular combustion-supporting air chamber 30 from the air inlet 36. Under the action of the curved surface of the inner ring of the annular combustion-supporting chamber 30, the air is sent to the end of the annular combustion-supporting chamber 30 far from the air inlet 36. While hitting the inner wall of the annular combustion-supporting chamber 30 at the end far from the air inlet 36, it changes from a horizontal state to a vertical state and is sent into the air inlet chamber 38 through the air inlet passage 47. When the outside air is turned on, the instantaneous flow rate becomes larger (which may also be caused by the power fluctuation of the outside air). Therefore, after passing through the curved surface of the inner ring of the annular combustion-supporting chamber 30, it impacts on the inner wall of the annular combustion-supporting chamber 30 at the end far from the air inlet 36, driving the combustion-supporting air inlet seat 29, the installation shell 20 connected to the combustion-supporting air inlet seat 29, and the outer sleeve fixing frame 31 connected to the installation shell 20 to oscillate on the surface of the calciner 1. The outer sleeve fixing frame 31 is detachably installed on the surface of the calciner 1 through blackened bolts. After repeatedly oscillating the installation shell 20 and the outer sleeve fixing frame 31 connected to the installation shell 20, the blackened bolts connecting the outer sleeve fixing frame 31 to the surface of the calciner 1 become loose, and there is a leakage gap between the outer sleeve fixing frame 31 and the surface of the calciner 1, resulting in heat leakage. By installing a shock-absorbing component at a position on the inner wall of the annular combustion-supporting air chamber 30 far from the air inlet 36, when the outside air impacts on the shock-absorbing component, the shock-absorbing component maximally removes this part of the impact force.

[0080] As Figure 5 shown, in one embodiment, the shock-absorbing component includes:

[0081] An arc-shaped buffer surface 41, which is formed at the top of the inner part of the annular combustion-supporting air chamber 30 at a position far from the air inlet 36;

[0082] An installation table 42, which is arranged obliquely on the surface of the combustion-supporting air inlet seat 29 corresponding to the arc-shaped buffer surface 41;

[0083] A metal elastic sheet 43, the cross-section of which is arc-shaped. The metal elastic sheet 43 is fixedly installed on the arc-shaped buffer surface 41 to form a sealed buffer chamber 53;

[0084] A self-rotating part 44, which is installed on the installation table 42, and the self-rotating part 44 extends into the sealed buffer chamber 53;

[0085] Connecting springs 45, two of the connecting springs 45 are symmetrically located in the sealed buffer chamber 53 with the self-rotating part 44 as the center. The connecting springs 45 are connected between the arc-shaped buffer surface 41 and the metal elastic sheet 43;

[0086] A reinforcing block 46, which is embedded and installed on the metal elastic sheet 43.

[0087] The working principle and beneficial effects of the above technical solution are:

[0088] The external wind impacts on the metal elastic sheet 43, driving the metal elastic sheet 43 to bend and deform towards the arc-shaped buffer surface 41. The connecting spring 45 contracts, and the air pressure in the sealed buffer chamber 53 is pressed into the self-rotating member 44, causing the self-rotating member 44 to rotate. The impact force is converted into the rotational force of the self-rotating member 44, thus playing a role in damping the combustion-supporting air inlet seat 29. When the instantaneous flow rate returns to normal, the impact force on the metal elastic sheet 43 decreases, and under the action of the connecting spring 45 returning to its original position, the metal elastic sheet 43 returns to its original state.

[0089] As Figure 6 , Figure 7 shown, in one embodiment, the self-rotating member 44 includes:

[0090] A fixed installation pipe 51, which is fixedly connected to the installation table 42;

[0091] A rotating cylinder 52, which is installed in the fixed installation pipe 51, and the rotating cylinder 52 extends into the sealed buffer chamber 53;

[0092] A sealing cover 54, which is threadedly connected to the fixed installation pipe 51;

[0093] A push rod installation groove 55, which is opened at the end of the rotating cylinder 52 close to the sealed buffer chamber 53;

[0094] A push rod 56, which is installed in the push rod installation groove 55, and the push rod 56 is arranged opposite to the strengthening block 46;

[0095] A central limiting rod 57, which is installed in the push rod installation groove 55 through a connecting frame, and the push rod 56 is sleeved on the central limiting rod 57;

[0096] A first spring 58, which is sleeved on the central limiting rod 57, and the first spring 58 is connected between the push rod 56 and the connecting frame;

[0097] An air inlet channel 59, and a plurality of the air inlet channels 59 are circumferentially opened at the end of the rotating cylinder 52 close to the sealed buffer chamber 53 with the push rod installation groove 55 as the center, and the air inlet channel 59 communicates with the push rod installation groove 55.

[0098] The working principle and beneficial effects of the above technical solution are:

[0099] When the metal elastic sheet 43 bends and deforms towards the arc-shaped buffer surface 41, the air in the sealed buffer chamber 53 is pressed into the mounting groove 55 through the air inlet channel 59. The air pressure in the mounting groove 55 increases, thereby driving the ejector rod 56 to move on the central limiting rod 57 in the stretching direction of the first spring 58. The ejector rod 56 extends out of the ejector rod mounting groove 55 and abuts against the reinforcing block 46 of the metal elastic sheet 43 in the bent state. Thus, when the metal elastic sheet 43 is at the maximum deformation amount, the ejector rod 56 abuts against the reinforcing block 46 to provide a stable support for the metal elastic sheet 43.

[0100] As Figure 6 , Figure 8 shown, in one embodiment, the self-rotating member 44 further includes:

[0101] An annular limiting groove 50, which is circumferentially formed on the inner wall of the fixed mounting tube 51;

[0102] A telescopic limiting block 61. A plurality of mounting grooves are circumferentially formed on the side end of the rotating cylinder 52. The telescopic limiting block 61 is installed in the mounting groove through a spring rod, and the telescopic limiting block 61 is adapted to the annular limiting groove 50;

[0103] An air inlet chamber 62, which is arranged in the rotating cylinder 52, and the bottom end of the ejector rod mounting groove 55 communicates with the air inlet chamber 62;

[0104] A driving inclined block 63. A plurality of driving inclined blocks 63 are circumferentially installed at the bottom end of the sealing cover 54. The straight line where the driving inclined block 63 is located points to the central end of the sealing cover 54, and the inclined surfaces of the driving inclined block 63 all face the same direction;

[0105] An inclined air outlet channel 64. A plurality of inclined air outlet channels 64 are circumferentially formed on the end of the rotating cylinder 52 far from the sealed buffer chamber 53 with the air inlet chamber 62 as the center, and the inclined air outlet channel 64 communicates with the air inlet chamber 62.

[0106] The working principle and beneficial effects of the above technical solution are:

[0107] When the metal elastic sheet 43 bends and deforms towards the arc-shaped buffer surface 41, the air in the sealed buffer chamber 53 is pressed into the mounting groove 55 from the air inlet channel 59. Part of the air passes through the connecting frame and enters the air inlet chamber 62 communicating with the mounting groove 55, and is sent out from the inclined air outlet channel 64 and blows on the driving inclined block 63 at the bottom end of the sealing cover 54. Since the sealing cover 54 is threadedly connected to the fixed mounting pipe 51, when the sealing cover 54 is screwed clockwise tightly, the strong air flow blowing on the driving inclined block 63 cannot drive the sealing cover 54 to rotate further clockwise, thus forcing the rotating column 52 to rotate within the fixed mounting pipe 51. In this way, the impact force is converted into the rotational force of the rotating column 52, thereby unloading the impact force and reducing the leakage gap between the outer sleeve fixing frame 31 and the surface of the calcination furnace 1 caused by the vibration of the mounting housing 20.

[0108] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
