Description

Technical Field

[0001] The invention relates to the technical field of glass production, and in particular to an intelligent high-temperature melting furnace for producing special glass. Background Art

[0002] The high-temperature melting process of glass is one of the key steps in producing glass. It mainly involves heating the raw materials to a high temperature to melt them into liquid glass. The existing production of flat glass generally uses a float glass production line, which transports the molten glass liquid through a float furnace to a pool of molten metal (usually tin), and uses the flow characteristics and buoyancy of the liquid to control the thickness of the glass. After a series of temperature control and annealing treatments, the glass of the required specifications is finally obtained.

[0003] Due to the early heating period of the glass melting process, smoke and harmful gases are easily generated at this time, which are directly discharged to the outside world and are harmful to health, so they need to be filtered and purified. The traditional method is to intercept fine particles in the smoke through filters and absorb and purify sulfur dioxide, nitrogen oxides, and carbon monoxide through purifiers. However, some smoke particles exist inside the material, rather than on the upper layer of the material. They are difficult to rise after being affected by the hot air flow, resulting in the inability to be directly removed and remaining inside the material, which ultimately makes the borosilicate glass produced likely to have substandard quality problems; not only that, when there is too much smoke, the filter will be partially blocked, resulting in a significant reduction in ventilation, affecting the efficiency of smoke exhaust and internal and external gas circulation. Summary of the invention

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] Embodiment 1:

[0038] See also Figure 1-4 , an intelligent high-temperature melting furnace for producing special glass, comprising a melting furnace body 1, the melting furnace body 1 comprising a heat-insulating furnace wall 11, a furnace bore 12 is arranged inside the heat-insulating furnace wall 11, a furnace chamber is used to store raw materials, a smoke exhaust duct 13 is arranged outside the furnace chamber, a smoke filter 14 and a purifier 15 are arranged on the inner wall of the smoke exhaust duct 13, a heating mechanism 2 is arranged outside the furnace chamber, and a stirring component 3 is arranged inside the furnace chamber;

[0039] The stirring component 3 includes a driving shaft 32, and a plurality of stirring blades 33 are fixedly connected to the driving shaft 32. The stirring blades 33 are responsible for mixing the raw materials. The ends of the plurality of stirring blades 33 are commonly provided with a debris removal component 4, and the debris removal component 4 rotates continuously following the stirring blades 33; the debris removal component 4 includes a first arc-shaped piece 41 and a second arc-shaped piece 42. A pair of first filter plates 43 are fixedly connected to the side ends of the first arc-shaped piece 41, and a pair of second filter plates 44 are fixedly connected to the side ends of the second arc-shaped piece 42. Powder filter holes 45 are provided on the first filter plates 43 and the second filter plates 44, and they are slidably connected.

[0040] Initially, the powder filter holes 45 on the first filter plate 43 and the second filter plate 44 block each other, so that the inner and outer chambers of the first arc-shaped sheet 41 and the second arc-shaped sheet 42 are not connected; when the set time is reached, the first filter plate 43 and the second filter plate 44 slide so that the powder filter holes 45 on them are staggered, and impurities rise with the hot air flow and are discharged from the smoke exhaust duct 13.

[0041] A float pool is arranged at the bottom of the melting furnace body 1, molten tin is arranged inside the float pool, and a liquid outlet is opened at the side end of the float pool, and the liquid outlet is used to discharge the glass liquid.

[0042] Specifically, the furnace bore 12 is made of high temperature resistant material, and the heat-insulating furnace wall 11 is made of heat-insulating material to prevent heat from being transferred to the outside. The heating mechanism 2 controls the heating time and heating temperature through a control unit. The heating mechanism 2 uses multiple heating tubes attached to the furnace bore 12. The raw materials of borosilicate glass in this case are mainly silica sand, borate, sodium alkali, limestone, magnesium, iron, etc., which generally need to be heated to 1400-1600 degrees to become liquid glass, and the heating time can be 4-6 hours.

[0043] The molten glass is transported through a float furnace to a pool of molten metal (tin liquid). The flow characteristics and buoyancy of the liquid are used to control the thickness of the glass. Through a series of temperature control and annealing treatments, glass of the desired specifications is finally obtained.

[0044] During the heating process, smoke and harmful gases are easily generated and directly discharged to the outside, which is harmful to health. Therefore, they need to be filtered and purified. In this case, the smoke filter 14 intercepts fine particles in the smoke, and the purifier 15 removes sulfur dioxide (SO2) and nitrogen oxides (NO x ), carbon monoxide (CO) is absorbed and purified. Initially, the raw materials have not melted yet and need to be fully stirred and evenly mixed by the stirring blades 33.

[0045] Specifically, the top of the driving shaft 32 is fixedly connected with a reduction motor 31 , and the reduction motor 31 is electrically connected to the control unit. The control unit can drive the reduction motor 31 to rotate forward and reverse, and control the corresponding rotation time.

[0046] A push plate 46 is fixedly connected to the inner side of the first arc-shaped piece 41, and a reset member 47 is provided between the first arc-shaped piece 41 and the second arc-shaped piece 42. When the first arc-shaped piece 41 rotates forward, the reset member 47 is squeezed, and the first filter plate 43 and the second filter plate 44 do not slide. When the first arc-shaped piece 41 rotates reversely, the reset member 47 pushes the second arc-shaped piece 42 away, so that the powder filter holes 45 on the first filter plate 43 and the second filter plate 44 are staggered.

[0047] Specifically, the reset member 47 includes a telescopic rod, which includes a hollow rod 471 and an inner rod 472. A reset spring 473 is fixedly connected between the bottom of the inner rod 472 and the inner wall of the hollow rod 471. The telescopic rod ensures the guidance of the moving paths of the first arc-shaped piece 41 and the second arc-shaped piece 42.

[0048] When the reduction motor 31 rotates forward with the drive shaft 32 (clockwise in the top view in the figure), the stirring blade 33 rotates with the first arc-shaped piece 41. During the rotation process, the push plate 46 rotates with the second arc-shaped piece 42. At this time, the two are in a merged state, and the filter powder holes 45 thereon are not staggered and blocked with each other. When the rotation is set for a time (for example, 20-60 minutes), the drive shaft 32 can be controlled to rotate in the opposite direction. At this time, the stirring blade 33 rotates in the opposite direction with the first arc-shaped piece 41, and the second arc-shaped piece 42 gradually moves away from the first arc-shaped piece 41. A reset spring 473 is provided to overcome the friction generated when the two slide. At this time, the first arc-shaped piece 41 and the second arc-shaped piece 42 rotate together, but the filter powder holes 45 thereon are staggered with each other. Some fine smoke particles enter the internal chambers of the first arc-shaped piece 41 and the second arc-shaped piece 42 from the filter powder holes 45, rise with the hot air flow, and go out of the smoke exhaust duct 13 together with the smoke, thereby improving the impurity removal efficiency and effectively preventing the smoke particles from penetrating into the raw material and not being flipped to the top.

[0049] When the drive shaft 32 rotates forward again, the first arc-shaped sheet 41 brings the first filter plate 43 to start pushing away the powder on the surface of the second filter plate 44 , achieving a cleaning effect and effectively avoiding the presence of powder between the first arc-shaped sheet 41 and the second arc-shaped sheet 42 .

[0050] Since the first filter plate 43 and the second filter plate 44 continuously rotate during the process of assisting smoke exhaust, the clogging of the powder filter holes 45 is effectively reduced.

[0051] According to actual needs, a hard-bristle brush can be embedded on the inner side of the first filter plate 43 and the outer side of the second filter plate 44. The hard-bristle brush is specifically a high-temperature resistant fine metal wire. The material can be nickel-based alloy or molybdenum alloy. It is not only resistant to high temperatures but also has elastic properties. When the first filter plate 43 and the second filter plate 44 are merged, the hard-bristle brush will enter the powder filter hole 45, further reducing the problem of the powder filter hole 45 being blocked.

[0052] See also Figure 5-7 In an embodiment further provided by the present invention, a flue anti-blocking component 5 is also provided inside the furnace bore 12, and the flue anti-blocking component 5 includes a spare pipe 51 fixedly connected to the outer end of the furnace bore 12, and a first blocking plate 52 and a second blocking plate 53 are respectively provided on the outside of the smoke exhaust duct 13 and the spare pipe 51, and a pair of rotating rods 54 are fixedly connected to the outer end of the driving shaft 32, and a driving component 6 is provided at the end of the rotating rod 54. The driving component 6 is used to push open only the first blocking plate 52 when the impurity removal component 4 rotates forward, and push open only the second blocking plate 53 when it rotates reversely, thereby completing the switching of the smoke exhaust path.

[0053] Furthermore, the driving component 6 includes a telescopic member 61 fixedly connected to the end of the rotating rod 54, the top of the telescopic member 61 is fixedly connected to an arc block 62, an elastic member is arranged inside the telescopic member 61, the first blocking plate 52 and the second blocking plate 53 are both provided with an arc groove 64, the inside of the arc groove 64 is slidably connected with a top shaft 65, the top shaft 65 is magnetically connected to one end of the inner cavity of the arc groove 64, and an elastic cotton 63 is fixedly connected to the other end of the inner cavity of the arc groove 64, and the elastic cotton 63 is responsible for returning to the initial position when the top shaft 65 is moved away.

[0054] Specifically, the telescopic member 61 is a telescopic rod, and an elastic member is arranged inside the telescopic rod. The specific arrangement method is the same as the above-mentioned reset member 47. The elastic member is a pressure spring. The outer wall of the top shaft 65 is fixedly sleeved with a magnetic ring, and the end of the arc groove 64 is embedded and connected with a magnetic sheet. Initially, the magnetic ring and the magnetic sheet are magnetically connected.

[0055] The above-mentioned magnetic materials can all be made of rare earth cobalt magnets, which can withstand 700-800 degrees. The magnetic rings and magnetic sheets are wrapped with high-temperature resistant protective covers. The protective covers are made of high-temperature resistant flexible materials and are located above the materials. Every time they approach the outlet, the temperature can be taken away by the external airflow to achieve the purpose of cooling. The actual ambient temperature is far below 1400 degrees.

[0056] The magnetic ring and the magnetic sheet can also be replaced by a clamping block and a buckle made of elastic material.

[0057] Furthermore, a clamping block 66 and a limiting plate 67 are fixedly connected to the inner wall of the furnace bore 12 , and the arc grooves 64 on the first blocking plate 52 and the second blocking plate 53 face opposite directions.

[0058] Specifically, in this case, two arc blocks 62 and telescopic members 61 and two pairs of limit plates 67 are provided. A pair of limit plates 67 can limit the position states of the first blocking plate 52 and the second blocking plate 53 to two positions.

[0059] Initially, the first blocking plate 52 is pushed open and limited by the block 66. At this time, the smoke is discharged from the smoke exhaust duct 13. At this time, it is a positive rotation. When one of the arc blocks 62 approaches the top shaft 65 of the first blocking plate 52, the elastic force of the elastic member below the arc block 62 is less than the magnetic force of the magnetic ring and the magnetic sheet. The telescopic member 61 begins to shrink and passes through the first blocking plate 52 smoothly. When the other arc block 62 reaches the top shaft 65 of the second blocking plate 53, since the top shaft 65 is close to the end, the arc block 62 causes the telescopic member 61 to shrink again.

[0060] When the driving shaft 32 rotates in the opposite direction, the smoke increases. If the smoke still passes through the smoke exhaust duct 13, the ventilation volume will be greatly reduced, and a spare pipe 51 is required. At this time, one of the arc blocks 62 rotates in the opposite direction. When it approaches the top shaft 65 of the first blocking plate 52, the plane of the arc block 62 contacts the top shaft 65, so that the telescopic member 61 cannot shrink. At this time, the rotation continues, and the rotation force exceeds the elastic force of the block 66 first, so that the first blocking plate 52 starts to rotate until it stops near the second limit plate 67. At this time, the rotation continues, which will exceed the magnetic force of the magnetic ring and the magnetic sheet, and the top shaft 65 will slide on the arc groove 64, so that the arc block 62 passes under the top shaft 65, completing the blocking of the smoke exhaust duct 13.

[0061] The other arc block 62 also rotates in the opposite direction at the same time, and can also push the second blocking plate 53 and stop it under the second limit plate 67 to open the spare channel. At this time, the smoke filter 14 inside the spare channel is not used and can filter the smoke.

[0062] After the smoke exhaust duct 13 is blocked, smoke and dust will slowly settle, gather together into particles and fall down.

[0063] If the smoke is not too great, it is sufficient to switch the direction of rotation two or three times before the raw material is turned into liquid.

[0064] If the smoke is too large, it can be switched multiple times, and when the smoke exhaust duct 13 or the spare channel is blocked, the external gas can be used to press the smoke filter 14 to complete the cleaning of its surface.

[0065] Stop switching just before the raw material becomes liquid.

[0066] Embodiment 2:

[0067] See also Figure 8-10 The difference between the second embodiment and the first embodiment is that the following technical features are added: a cleaning component 7 is provided at the side end of the smoke filter net 14, and the cleaning component 7 includes a cleaning brush 71 sliding on the outer end of the smoke filter net 14, and the side end of the cleaning brush 71 is fixedly connected to a driven rod 72, and the end of the driven rod 72 is fixedly sleeved with a driven gear 73.

[0068] An active rod 74 is rotatably connected to both the smoke exhaust duct 13 and the standby pipe 51 . A driving gear 75 is fixedly sleeved on the bottom of the active rod 74 . The driving gear 75 is meshedly connected to the driven gear 73 .

[0069] A switching component 8 is provided on the cleaning component 7, and the switching component 8 includes a first driving ring 81 and a second driving ring 82 which are sleeved on the driving shaft 32. The first driving ring 81 and the second driving ring 82 are provided with helical teeth 83 inside, and a compression spring 84 is provided between the helical teeth 83 and the inner wall of the first driving ring 81. The switching component 8 is responsible for exchanging and driving a pair of active rods 74 to rotate.

[0070] Attached Figure 8 These are two top views of the first drive ring 81 and the second drive ring 82 . It can be seen from the figures that the bevel teeth 83 of the two drive rings face in opposite directions.

[0071] Specifically, a plurality of paddles are fixedly connected to the outer walls of the driving shaft 32 close to the first driving ring 81 and the second driving ring 82 .

[0072] In an embodiment further provided by the present invention, pulleys 85 are sleeved on the outside of the first drive ring 81, the second drive ring 82 and the active rod 74, a transmission belt 86 is sleeved on a pair of adjacent pulleys 85, and a slag bucket 87 is provided at the bottom of the smoke exhaust duct 13 and the spare pipe 51.

[0073] Specifically, the outsides of the first drive ring 81 , the second drive ring 82 and the active rod 74 are all fixedly sleeved with pulleys 85 , and the outsides of a corresponding pair of pulleys 85 are sleeved with transmission belts.

[0074] When the rotation direction is switched, the drive shaft 32 rotates in the opposite direction, and the bevel teeth 83 are pushed to rotate through the paddle, so that the first drive ring 81 rotates accordingly, and the first drive ring 81 and the pulley 85 start to rotate, and the active rod 74 rotates through the transmission belt 86, and finally the driven rod 72 rotates with the cleaning brush 71, and the foreign particles adhering to the smoke filter 14 are cleaned, so as to effectively prevent the smoke filter 14 from being blocked.

[0075] At this time, the second drive ring 82 will press the compression spring 84 when rotating, because the direction of the helical teeth 83 is opposite to that of the first drive ring 81, and will not cause the second drive ring 82 to rotate.

[0076] Subsequently, when switching to forward rotation, the smoke filter 14 inside the spare pipe 51 can be cleaned, and finally the two smoke filter nets 14 can be intermittently cleaned, and the settled smoke particles enter the slag receiving bucket 87, which can be cleaned later.

[0077] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
