[0031] Please refer to Figures 1-5 , the present utility model provides a technical solution: a heating furnace for silica sol production, including a silica sol heating furnace 1, a furnace door guide rail 2 fixedly connected to the front end of the silica sol heating furnace 1, a plugging assembly arranged inside the furnace door guide rail 2, and a material taking assembly arranged inside the silica sol heating furnace 1. The material taking assembly includes a silica sol placement plate 16, the silica sol placement plate 16 is slidably connected inside the silica sol heating furnace 1, two connecting plates 17 are fixedly connected to the lower end of the silica sol placement plate 16, both of the two connecting plates 17 are slidably connected to the silica sol heating furnace 1, a first hydraulic rod 18 is fixedly connected inside the silica sol heating furnace 1, the output end of the first hydraulic rod 18 is rotatably connected to a gear 19, a first rack 20 is fixedly connected to the lower end of the silica sol placement plate 16, a second rack 21 is fixedly connected to the inner wall of the silica sol heating furnace 1, and both the first rack 20 and the second rack 21 are engaged with the gear 19.

[0032] The material taking assembly further includes a second furnace door 4, the second furnace door 4 is hinged to the front end of the silica sol heating furnace 1, a limiting plate 25 is fixedly connected to the lower end of the silica sol placement plate 16, a support rod 22 is hinged to the lower end of the silica sol placement plate 16, two rollers 23 are rotatably connected to the outer side of the support rod 22, and a second hydraulic rod 24 is hinged to the lower end of the silica sol placement plate 16, and the output end of the second hydraulic rod 24 is hinged to the support rod 22.

[0033] The plugging assembly includes a first furnace door 3, the first furnace door 3 is slidably connected to the furnace door guide rail 2, a connecting block 7 is fixedly connected to the surface of the first furnace door 3, a limiting block 8 is fixedly connected to the inner wall of the furnace door guide rail 2, the number of both the connecting block 7 and the limiting block 8 is four, and they are symmetrically arranged on the left and right sides of the first furnace door 3 respectively. Two electric hoists 5 are installed at the upper end of the furnace door guide rail 2, furnace door traction ropes 6 are wound around the surfaces of both the two electric hoists 5, and one end of each of the two furnace door traction ropes 6 away from the corresponding electric hoist 5 is fixedly connected to the first furnace door 3.

[0034] A gas pipeline 14 is fixedly connected to the surface of the silica sol heating furnace 1, four gas nozzles 15 are fixedly connected to the inner side of the gas pipeline 14, and all four gas nozzles 15 extend into the silica sol heating furnace 1.

[0035] At the upper end of the silica sol heating furnace 1, a blower 9 is fixedly installed. At the upper end of the silica sol heating furnace 1, a filter box 10 is fixedly connected. At the input end of the filter box 10, a first air outlet pipe 11 is fixedly connected. At the output end of the filter box 10, a second air outlet pipe 12 is fixedly connected. Inside the filter box 10, three filter nets 13 are arranged.

[0036] Heat insulation plates are fixedly connected to the inner wall of the silica sol heating furnace 1, the surface of the second furnace door 4, and the surface of the silica sol placement plate 16.

[0037] When using this device, first start the electric hoist 5 to drive the furnace door towing rope 6 to wind around the surface of the electric hoist 5. The furnace door towing rope 6 drives the first furnace door 3 to rise. The first furnace door 3 drives the connecting block 7 to slide on the inner wall of the furnace door guide rail 2, so that the first furnace door 3 is separated from the front side of the silica sol heating furnace 1, facilitating the exposure of the silica sol placement plate 16 inside the silica sol heating furnace 1. Then, place the silica sol on the surface of the silica sol placement plate 16, introduce gas into the gas pipeline 14, and ignite the gas. The silica sol heating furnace 1 starts the blower 9 to suck the air outside the silica sol heating furnace 1 into the inside of the silica sol heating furnace 1, facilitating the maintenance of gas combustion.

[0038] Start the electric hoist 5 again to drive the furnace door towing rope 6 to rotate on its surface. The furnace door towing rope 6 drives the first furnace door 3 to move, and the first furnace door 3 descends under the action of its own gravity. The first furnace door 3 drives the connecting block 7 to slide inside the furnace door guide rail 2, and the connecting block 7 contacts the limit block 8. Through the mutual extrusion of the two inclined surfaces of the connecting block 7 and the limit block 8, it is convenient to bring the first furnace door 3 close to the surface of the silica sol heating furnace 1 to seal the silica sol heating furnace 1, prevent heat and flame from leaking from the first furnace door 3, reduce heat loss, and improve the safety of this device.

[0039] Since the gas combustion will generate certain waste gas, the waste gas inside the silica sol heating furnace 1 is discharged from the first air outlet pipe 11 into the inside of the filter box 10, and the three filter nets 13 are used to filter the waste gas, and then discharged from the second air outlet pipe 12, facilitating the collection of the waste gas and the secondary treatment of the waste gas, preventing the waste gas from being directly discharged into the atmosphere and affecting the surrounding environment.

[0040] Since heat insulation plates are fixedly installed on the inner wall of the silica sol heating furnace 1 and the surface of the silica sol placement plate 16, through effective heat insulation, the heat generated by fuel combustion is more used for heating workpieces rather than being dissipated into the environment, facilitating the reduction of heat loss, improving the thermal efficiency of the heating furnace, and reducing energy consumption.

[0041] After the heating of the silica sol is completed, open the first furnace door 3 again to expose the silica sol placement plate 16 and the silica sol. Open the second furnace door 4 to make the second furnace door 4 rotate at the front end of the silica sol heating furnace 1. When it is necessary to take out the silica sol, start the first hydraulic rod 18 to drive the gear 19 to move. The gear 19 moves and rotates on the surface of the second rack 21. Due to the limitation of the gear 19 by the second rack 21, it is convenient for the gear 19 to drive the first rack 20 to move outside the silica sol heating furnace 1. The first rack 20 drives the silica sol placement plate 16 and the connecting plate 17 to move outside the silica sol heating furnace 1, so that the silica sol placement plate 16 moves to the outside of the silica sol heating furnace 1. By sliding the connecting plate 17 inside the silica sol heating furnace 1, it is convenient to limit the position of the silica sol placement plate 16. Start the second hydraulic rod 24 to drive the support rod 22 to rotate at the lower end of the silica sol placement plate 16. The support rod 22 drives the roller 23 to rotate and makes the support rod 22 contact the limit plate 25, which is convenient for the limit plate 25 to limit the position of the support rod 22, preventing the support rod 22 and the roller 23 from moving excessively during the movement, affecting the stability of the support rod 22, facilitating the support of the silica sol placement plate 16, and facilitating the silica sol placement plate 16 to maintain stability during the outward movement, improving the stability of the silica sol placement plate 16 during movement.

[0042] When the silica sol placement plate 16 moves to the outside of the silica sol heating furnace 1, it is convenient to expose the silica sol on its surface, convenient to use tools to take out the silica sol, making it easier to approach and move the silica sol placement plate 16, simplifying the operation process, improving work efficiency, being able to quickly remove the silica sol from the heating furnace, helping to reduce safety risks during the operation, and protecting the personal safety of the staff.

[0043] Furthermore, by moving the silica sol placement plate 16 and the connecting plate 17 inside the silica sol heating furnace 1, and at the same time the support rod 22 and the roller 23 support the silica sol placement plate 16, it is convenient for the silica sol placement plate 16 to move stably, improving the stability of the silica sol placement plate 16 during movement, convenient to use tools to take out the silica sol, making it easier to approach and move the silica sol placement plate 16, simplifying the operation process, improving work efficiency, being able to quickly remove the silica sol from the heating furnace, helping to reduce safety risks during the operation, protecting the personal safety of the staff, and improving the safety of the device.

[0044] The waste gas generated by the combustion of the gas is initially filtered by the filter screen 13, which is convenient for removing solid impurities, liquid impurities and other harmful substances in the waste gas, reducing its pollution to the environment, convenient for subsequent purification treatment of the waste gas, and improving the practicability and safety of the device.

[0045] Working principle: When using this device, first start the electric hoist 5 to drive the furnace door towing rope 6 to wind around the surface of the electric hoist 5. The furnace door towing rope 6 drives the first furnace door 3 to rise. The first furnace door 3 drives the connecting block 7 to slide on the inner wall of the furnace door guide rail 2, so that the first furnace door 3 is separated from the front side of the silica sol heating furnace 1, facilitating the exposure of the silica sol placement plate 16 inside the silica sol heating furnace 1. Then, place the silica sol on the surface of the silica sol placement plate 16, introduce gas into the gas pipeline 14, and ignite the gas. The silica sol heating furnace 1 starts the blower 9 to suck the air outside the silica sol heating furnace 1 into the inside of the silica sol heating furnace 1, facilitating the maintenance of gas combustion.

[0046] Start the electric hoist 5 again to drive the furnace door towing rope 6 to rotate on its surface. The furnace door towing rope 6 drives the first furnace door 3 to move, and the first furnace door 3 descends under the action of its own gravity. The first furnace door 3 drives the connecting block 7 to slide inside the furnace door guide rail 2 and makes the connecting block 7 contact the limit block 8. Through the mutual extrusion of the two inclined surfaces of the connecting block 7 and the limit block 8, it is convenient to bring the first furnace door 3 close to the surface of the silica sol heating furnace 1 to seal the silica sol heating furnace 1, prevent heat and flame from leaking from the first furnace door 3, reduce heat loss, and improve the safety of this device.

[0047] Since the combustion of gas will generate certain waste gas, the waste gas inside the silica sol heating furnace 1 is discharged from the first air outlet pipe 11 into the inside of the filter box 10, and three filter meshes 13 are used to filter the waste gas, and then discharged from the second air outlet pipe 12, facilitating the collection of waste gas and the secondary treatment of waste gas, preventing the direct discharge of waste gas into the atmosphere and affecting the surrounding environment.

[0048] Since heat insulation plates are fixed on the inner wall of the silica sol heating furnace 1 and the surface of the silica sol placement plate 16, through effective heat insulation, the heat generated by fuel combustion is more used for heating workpieces rather than dissipating into the environment, facilitating the reduction of heat loss, improving the thermal efficiency of the heating furnace, and reducing energy consumption.

[0049] After the heating of the silica sol is completed, open the first furnace door 3 again to expose the silica sol placement plate 16 and the silica sol. Open the second furnace door 4 so that the second furnace door 4 rotates at the front end of the silica sol heating furnace 1. When it is necessary to take out the silica sol, start the first hydraulic rod 18 to drive the gear 19 to move. The gear 19 moves and rotates on the surface of the second rack 21. Due to the restriction of the gear 19 by the second rack 21, it is convenient for the gear 19 to drive the first rack 20 to move outside the silica sol heating furnace 1. The first rack 20 drives the silica sol placement plate 16 and the connecting plate 17 to move outside the silica sol heating furnace 1, so that the silica sol placement plate 16 moves to the outside of the silica sol heating furnace 1. By sliding the connecting plate 17 inside the silica sol heating furnace 1, it is convenient to limit the position of the silica sol placement plate 16. Start the second hydraulic rod 24 to drive the support rod 22 to rotate at the lower end of the silica sol placement plate 16. The support rod 22 drives the roller 23 to rotate and makes the support rod 22 contact the limiting plate 25, which is convenient for the limiting plate 25 to limit the support rod 22 and prevent the support rod 22 and the roller 23 from moving excessively during the movement, affecting the stability of the support rod 22, facilitating the support of the silica sol placement plate 16, facilitating the silica sol placement plate 16 to maintain stability during the outward movement, and improving the stability of the silica sol placement plate 16 during movement.

[0050] When the silica sol placement plate 16 moves to the outside of the silica sol heating furnace 1, it is convenient to expose the silica sol on its surface, convenient to use tools to take out the silica sol, making it easier to access and move the silica sol placement plate 16, simplifying the operation process, improving work efficiency, being able to quickly remove the silica sol from the heating furnace, helping to reduce safety risks during the operation, and protecting the personal safety of the staff.

[0051] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
