[0002] The traditional glass bottle production process is mainly to add the proportioned glass bottle raw materials to the kiln. The glass bottle raw materials include quartz sand, calcite, lithium feldspar, soda ash, which account for a large proportion, and carbon powder, selenium powder and clarifier, which account for a small proportion. In the kiln, the glass bottle raw materials are burned by the flame sprayed by the flame spray gun to become molten glass liquid, and a large amount of smoke is generated. The molten glass liquid passes through the material channel and the shearing mechanism to become glass drips, and the glass drips enter the determinant bottle making machine. The smoke is discharged from the smoke outlet of the kiln. In order to avoid environmental pollution, the smoke must be processed by the desulfurization and denitrification equipment, and finally discharged into the air through the chimney, and powdered by-products such as sodium sulfate and sodium carbonate are obtained. Stacked in the unloading bin of the desulfurization and denitrification equipment.

[0055] The embodiment of the present invention provides a kiln smoke recovery and raw material proportioning and mixing melting system, which overcomes the disadvantage of the background technology that the powdered by-products obtained by the kiln smoke after passing through the desulfurization and denitrification equipment are easily treated as waste and cause environmental pollution; it realizes the technical effect of conveniently recycling the by-products obtained by the smoke after desulfurization and denitrification, automatically transporting and proportioning them, and then mixing them with glass bottle raw materials and adding them to the kiln, thereby reducing environmental pollution and saving the cost of glass bottle raw materials.

[0056] The overall idea of ​​the technical solution of the embodiment of the present invention is as follows:

[0057] The main material supply device is used for the components that account for a larger proportion of the glass bottle raw materials, and the auxiliary supply device is used for the components that account for a smaller proportion. The by-products obtained by the desulfurization and denitrification equipment of the smoke are recycled, and the by-product supply device is used to recycle the smoke. The vacuum pump is used to automatically transport the by-products from the desulfurization and denitrification equipment to the by-product storage bin. The by-products account for a small proportion of the glass bottle raw materials. The first screw extruder is used to accurately control the flow of by-products entering the first weighing metering bin, which helps to avoid imbalance in the ratio. The demand for auxiliary materials is small, and the cost of using a bucket elevator to transport auxiliary materials is high, so the packaging bags are selected to transport auxiliary materials. The elevator is manually used to lift multiple auxiliary material packaging bags to the top floor of the batching building. The mesh frame blanking machine is located on the top floor of the batching building. The staff opens the packaging bag and pours the auxiliary materials into the mesh frame blanking machine, and then the auxiliary materials fall into the auxiliary material storage bin. The second screw extruder is used to accurately control the flow of auxiliary materials entering the second weighing metering bin. The demand for main materials is large, and bucket elevators are used to transport the main materials, which has high transportation efficiency. The entrance of the bucket elevator is on the ground floor of the batching building, and the exit of the bucket elevator is on the top floor of the batching building. The staff first drives a forklift to transport the main materials to the entrance of the bucket elevator, and the bucket elevator transports the main materials to the main material storage bin. The vibrating feeder quickly transports the main materials from the main material storage bin to the third weighing metering bin.

[0058] The weighing metering silo discharges the glass bottle raw materials of the specified weight ratio into the first belt conveyor. The raw bottle materials are stirred and mixed in the mixer and then reach the furnace side silo through the second belt conveyor. The feeder pushes the glass bottle raw materials into the kiln. The glass bottle raw materials become molten liquid under high temperature and produce smoke, which flows to the desulfurization and denitrification equipment.

[0059] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0060] See also Figures 1 to 16 , a preferred embodiment of the present invention.

[0061] A kiln smoke recovery and raw material proportioning mixed melting system, comprising:

[0062] Raw material proportioning and mixing equipment 1, kiln melting equipment 2 and desulfurization and denitrification equipment 3;

[0063] The raw material proportioning and mixing device 1 comprises a tobacco recovery byproduct supply device 11, an auxiliary material supply device 12, a main material supply device 13 and a mixing and transporting device 14;

[0067] The mixed transport device 14 includes a first belt conveyor 141, a mixer 142 and a second belt conveyor 143. The outlets of the first weighing metering silo 114, the second weighing metering silo 124 and the third weighing metering silo 134 are all connected to the inlet of the first belt conveyor 141, the outlet of the first belt conveyor 141 is connected to the inlet of the mixer 142, and the outlet of the mixer 142 is connected to the inlet of the second belt conveyor 143;

[0068] The kiln melting equipment 2 includes a furnace side silo 21, a feeder 22 and a kiln 23, wherein the inlet of the furnace side silo 21 is connected to the outlet of the second belt conveyor 143, the outlet of the furnace side silo 21 is connected to the inlet of the feeder 22, and the outlet of the feeder 22 is connected to the feed inlet of the kiln 23;

[0069] The smoke exhaust port of the kiln 23 is connected to the smoke inlet 31 of the desulfurization and denitration equipment 3, and the byproduct discharge port 32 of the desulfurization and denitration equipment 3 is connected to the inlet of the vacuum suction machine.

[0070] The present invention uses a vacuum pump 111 to automatically transport the by-products from the desulfurization and denitrification equipment 3 to the by-product storage bin 112, and then the first screw feeder 113 transports the by-products to the first weighing metering bin 114 for accurate proportioning. The auxiliary materials, which account for a smaller proportion of glass bottle raw materials, enter the auxiliary material storage bin 122 from the mesh frame blanking machine 121 and then pass through the second screw feeder 123 and the second weighing metering bin 124 for accurate proportioning. The main materials, which account for a larger proportion of glass raw materials, are transported from the bucket elevator 114 to the first weighing metering bin 114 for accurate proportioning. 131 enters the main material storage bin 132, and then enters the third weighing metering bin 134 through the vibrating feeder 133 for rapid proportioning. The proportioned raw materials are mixed in the mixer 142 and transported to the kiln melting equipment 2. The smoke generated by the kiln melting equipment 2 enters the desulfurization and denitrification equipment 3; the by-products obtained by desulfurization and denitrification of the smoke are conveniently recycled, automatically transported and proportioned, and then mixed with the glass bottle raw materials and added to the kiln 23, thereby reducing environmental pollution and saving the cost of glass bottle raw materials.

[0071] Combination Figure 1 , factories producing glass bottles usually build a batching building 4 for installing raw material proportioning and mixing equipment 1, and a melting building 5 for installing kiln melting equipment 2 and desulfurization and denitrification equipment 3. By-products account for a small proportion of the entire glass bottle raw materials. After the by-products are sucked into the by-product storage bin 112, the first screw extruder is used to accurately control the by-product flow entering the first weighing metering bin 114, which helps to avoid imbalance in the proportion. The by-product discharge port 32 of the desulfurization and denitrification equipment 3 is connected to the discharge bin, and the inlet of the vacuum suction machine is connected to the discharge bin through a material transport pipeline. According to actual production needs, a part of the by-products is used as glass bottle raw materials, and the other part of the by-products is transported out by trucks as other raw materials.

[0072] The auxiliary materials account for a small proportion of the entire glass bottle raw materials, and the demand for auxiliary materials is small. The cost of using a bucket elevator 131 to transport auxiliary materials is high, so the auxiliary materials are transported in packaging bags. A plurality of auxiliary material packaging bags are manually lifted to the top floor of the batching building 4 using an elevator. The mesh frame blanking machine 121 is located on the top floor of the batching building 4. The staff opens the packaging bags and pours the auxiliary materials into the mesh frame blanking machine 121, and then the auxiliary materials fall into the auxiliary material storage bin 122. The second screw extruder is used to accurately control the flow of auxiliary materials entering the second weighing metering bin 124. The mesh plate 1212 and frame 1211 of the mesh frame blanking machine 121 prevent large foreign objects from falling into the auxiliary material storage bin 122, and prevent the situation of manual falling into the auxiliary material storage bin 122.

[0073] The main material accounts for a large proportion of the entire glass bottle raw materials, and the demand for the main material is large. The bucket elevator 131 is used to transport the main material, and the transportation efficiency is high. The entrance of the bucket elevator 131 is on the bottom floor of the batching building 4, and the exit of the bucket elevator 131 is on the top floor of the batching building 4. The staff first drives a forklift to transport the main material to the entrance of the bucket elevator 131, and the bucket elevator 131 transports the main material to the main material storage bin 132; compared with the screw extruder, the vibrating feeder 133 can quickly transport the main material from the main material storage bin 132 to the third weighing metering bin 134, saving the main material supply time.

[0074] The first weighing metering silo 114 is electrically connected to the MCU 115 for by-products, the second weighing metering silo 124 is electrically connected to the MCU 125 for auxiliary materials, and the third weighing metering silo 134 is electrically connected to the MCU 135 for main materials. The MCU 115 for by-products, the MCU 125 for auxiliary materials, and the MCU 135 for main materials are all integrated in the industrial computer. The staff operates the industrial computer and sends corresponding weighing threshold signals to the MCU 115 for by-products, the MCU 125 for auxiliary materials, and the MCU 135 for main materials according to the raw material ratio. When the weighing sensor of the weighing metering silo detects that the weight of the raw materials in the silo reaches the specified weighing threshold, the discharge valve of the weighing metering silo is opened for discharge; after the weighing metering silo becomes an empty silo, the discharge valve of the weighing metering silo is closed. According to the actual production requirements of glass bottles, the ratio of glass bottle raw materials will be different. At this time, the staff only needs to operate the industrial computer to change the set weighing threshold parameters, which is convenient and quick.

[0075] The desulfurization and denitrification equipment 3 can refer to the utility model patent document "A glass kiln fully green and clean production process equipment" with announcement number CN210699488U.

[0076] There are four main material supply devices 13, which are used to supply quartz sand, calcite, lithium feldspar and soda ash respectively; there are three auxiliary material supply devices 12, which are used to supply carbon powder, selenium powder and clarifier respectively; the tobacco recovery by-product supply device 11 is used to supply sodium sulfate or sodium carbonate. For example, quartz sand accounts for 30%-50%, calcite accounts for 10%-15%, lithium feldspar accounts for 10%-20%, soda ash accounts for 10%-20%, sodium sulfate or sodium carbonate accounts for 0.2%-1%, carbon powder accounts for 2%-4%, selenium powder accounts for 2%-4%, and clarifier accounts for 0.2%-1%.

[0077] The auxiliary material supply device 12 further includes an auxiliary material MCU 125, which is electrically connected to the second screw feeder 123 and the second weighing metering silo 124. The auxiliary material MCU 125 stores a feeding threshold and a discharging threshold, and the second weighing metering silo 124 sends the weighing value to the auxiliary material MCU 125;

[0078] When the weighing value is higher than the discharge threshold, the auxiliary material MCU 125 sends a stop feeding signal to the second screw feeder 123, and then sends a start discharge signal to the discharge valve of the second weighing metering silo 124;

[0079] When the weighing value is lower than the refilling threshold, the auxiliary material MCU 125 sends a stop discharging signal to the discharging valve of the second weighing metering bin 124, and then sends a start refilling signal to the second screw feeder 123. The beneficial effect of this technical solution is that according to the specified raw material ratio, the auxiliary material supply device 12 automatically and orderly performs refilling, weighing, and discharging, thereby improving efficiency.

[0080] The mesh frame blanking machine 121 includes a frame 1211, a mesh plate 1212, a cover plate 1213, a flip drive assembly 1214 and an operation panel (not shown), wherein the frame 1211 is fixedly arranged at the entrance of the auxiliary material storage bin 122, the mesh plate 1212 is fixedly connected to the frame 1211, the cover plate 1213 is connected to the frame 1211 via the flip drive assembly 1214, the cover plate 1213 can cover the mesh plate 1212, the operation panel is electrically connected to the flip drive assembly 1214, and the auxiliary material MCU 125 is also electrically connected to the flip drive assembly 1214;

[0081] The auxiliary material MCU125 also stores the refill waiting time. After the auxiliary material MCU125 sends the refill start signal to the second screw feeder 123, the timing function is turned on. If the accumulated time is equal to the refill waiting time and the weighing value is still lower than the refill threshold, the auxiliary material MCU125 controls the flip drive assembly 1214 to open the cover 1213. When the weighing value is higher than the refill threshold, the accumulated time is reset and the auxiliary material MCU125 turns off the timing function. The beneficial effect of this technical solution is that when the auxiliary material storage bin 122 is empty, even if the second screw feeder 123 is in the started state, no auxiliary material enters the second weighing metering bin 124. For example, the waiting time for replenishing is five seconds. After five seconds, the weighing value of the second weighing metering bin 124 is still lower than the replenishing threshold, for example, the replenishing threshold is zero. At this time, the auxiliary material MCU 125 controls the flip drive component 1214 to open the cover 1213. When the staff sees that the cover 1213 is in the open state, they understand that they need to replenish the auxiliary material storage bin 122. The staff opens the auxiliary material packaging bag and pours the auxiliary material on the mesh plate 1212. The auxiliary material falls into the auxiliary material storage bin 122 through the mesh holes of the mesh plate 1212. The staff closes the cover 1213 through the operation panel, which helps to prevent impurities from entering the auxiliary material storage bin 122.

[0082] The raw material proportioning and mixing device 1 also includes a cullet supply device 15, which includes a cullet weighing metering bin 151, a cullet material vibrating feeder 152 and a cullet MCU 153, the outlet of the cullet weighing metering bin 151 is connected to the inlet of the cullet vibrating feeder 133, the outlet of the cullet vibrating feeder 133 is located above the second belt conveyor 143, the cullet MCU 153 is electrically connected to the cullet vibrating feeder 133 and the second belt conveyor 143, and the vibration frequency of the cullet vibrating feeder 133 is positively correlated with the transportation speed of the second belt conveyor 143. The beneficial effect of this technical solution is that the cullet 154 is recycled and utilized, cost is saved, and the cullet 154 is weighed and fed into the kiln 23 for melting at the same time as the mixed material 144. The faster the transport speed of the second belt conveyor 143, the greater the vibration frequency of the cullet vibrating feeder 133, and the slower the transport speed of the second belt conveyor 143, the smaller the vibration frequency of the cullet vibrating feeder 133; the vibrating feeder 133 gradually transports the materials by vibration. The mixer 142 scatters the mixed material on the second belt conveyor 143; the cullet 154 is spread more evenly on the mixed material 144 of the second belt conveyor 143, and is mixed with the mixed material 144 in the process of falling into the furnace side silo 21.

[0083] The first belt conveyor 141 includes a machine base 1411, a driving wheel 1412, a driven wheel 1413, a belt 1414, a horizontal support roller 1415 and an inclined side blocking roller 1416. The driving wheel 1412 is rotatably arranged at the front end of the machine base 1411, the driven wheel 1413 is rotatably arranged at the rear end of the machine base 1411, the horizontal support roller 1415 is rotatably arranged at the upper part of the machine base 1411, and a plurality of horizontal support rollers 1415 are arranged at intervals along the length direction of the machine base 1411. The inclined side blocking rollers 1416 are arranged on the left and right sides of each horizontal support roller 1415. The belt 1414 is wound around the driving wheel 1412, the driven wheel 1413, the horizontal support roller 1415 and the inclined side blocking roller 1416. The inclined side blocking rollers 1416 make the left and right sides of the belt 1414 tilt upward. The beneficial effect of this technical solution is that the glass bottle raw material moves on the belt 1414 with the movement of the belt 1414; the left and right sides of the belt 1414 are tilted upward to effectively prevent the glass bottle raw material from falling off the belt 1414 during transportation. The belt 1414 has a certain elasticity and is adapted to the structural shape composed of the horizontal support roller 1415 and the inclined side blocking roller 1416.

[0084] The feeder 22 includes a frame 221, a telescopic drive assembly 222, a push plate 223, a slide bar 224 and an intermittent swing assembly. The frame 221 is fixedly connected to the kiln 23. The frame 221 has a feeding chamber 2211. The entrance of the feeding chamber 2211 is connected to the exit of the furnace side silo 21. The exit of the feeding chamber 2211 is connected to the entrance of the kiln 23. The push plate 223 is located in the feeding chamber 2211. The push plate 223 is fixedly connected to the front end of the slide bar 224. The telescopic drive assembly 222 is used to drive the rear end of the slide bar 224. The intermittent swing assembly is used to change the swing angle of the slide bar 224.

[0085] When the slide bar 224 moves forward, the slide bar 224 is in a horizontal state. When the slide bar 224 moves backward, the front end of the slide bar 224 rotates counterclockwise first and then clockwise. The maximum swing angle of the front end of the slide bar 224 is an acute angle. When the slide bar 224 moves backward to the initial position, the slide bar 224 becomes horizontal. The beneficial effect of this technical solution is that the glass bottle raw material 6 enters the feeding chamber 2211 from the furnace side bin 21, and the push plate 223 pushes the glass bottle raw material 6 into the kiln 23 when moving forward; when the push plate 223 moves backward, the slide bar 224 swings, causing the push plate 223 to move backward in an arc upward, effectively avoiding pushing the glass bottle raw material 6 away from the kiln 23, and ensuring that the kiln 23 is fed with the material.

[0086] The telescopic driving assembly 222 includes a driving motor 2221, a rotating wheel 2222 and a connecting rod 2223. The body of the driving motor 2221 is fixedly connected to the frame 221. The output shaft of the driving motor 2221 is drivingly connected to the rotating wheel 2222. The front end of the connecting rod 2223 is hinged to the rear end of the sliding rod 224. The rear end of the connecting rod 2223 is hinged to the rotating wheel 2222.

[0087] The intermittent swing component is a sleeve 225, which has a sliding hole 2251. The sleeve 225 is fixedly connected to the frame 221, and the sliding rod 224 passes through the sliding hole 2251. The height of the sliding hole 2251 is greater than the height of the sliding rod 224. When the sliding rod 224 is in a horizontal state, the lower surface of the sliding rod 224 contacts the bottom side wall of the sliding hole 2251. The beneficial effect of this technical solution is that the rotating wheel 2222 rotates clockwise. In the first half of the rotation of the rotating wheel 2222, when the rotating wheel 2222 moves the sliding bar 224 forward from the initial position through the connecting rod 2223, the sliding bar 224 contacts the bottom side wall of the sliding hole 2251, and the sliding bar 224 is in a horizontal state. The pushing plate 223 pushes the glass bottle raw material 6 in the feeding chamber 2211 into the kiln 23; in the second half of the rotation of the rotating wheel 2222, the rotating wheel 2222 applies a backward and downward force to the rear end of the sliding bar 224 through the connecting rod 2223. In the process of retreating, the sliding bar 224 uses the sleeve 225 as a fulcrum, and the front end of the sliding bar 224 tilts upward, thereby causing the pushing plate 223 to retreat in an upward arc; when the sliding bar 224 retreats to the initial position, the sliding bar 224 returns to a horizontal state.

[0088] The kiln melting equipment 2 also includes a cooling water supply device 24, which includes a cooling tower 241, a water tank 242, a water pump 243, a water inlet pipe 244 and a water outlet pipe 245. The sliding rod 224 has a cavity inside, and the push plate 223 has a U-shaped pipe 2231 inside. The water inlet pipe 244 and the water outlet pipe 245 extend into the cavity from the rear end of the sliding rod 224. The lower end of the U-shaped pipe 2231 is communicated with the water inlet pipe 244, and the upper end of the U-shaped pipe 2231 is communicated with the water outlet pipe 245. The outlet of the water pump 243 is communicated with the water inlet pipe 244, the inlet of the cooling tower 241 is communicated with the water outlet pipe 245, the outlet of the cooling tower 241 is connected to the inlet of the water tank 242, and the outlet of the water tank 242 is connected to the inlet of the water pump 243. The beneficial effect of this technical solution is that the push plate 223 is subjected to the high temperature of the kiln 23, and the heat of the push plate 223 is absorbed by cooling water, thereby reducing the temperature of the push plate 223 and improving the service life of the push plate 223. The water inlet pipe 244 and the water outlet pipe 245 are hoses. There are slide bars 224 at both ends of the push plate 233, the slide bar at the left end is connected to the sleeve 225, and the slide bar at the right end has the cavity.

[0089] The feeder 22 further includes a pressure sensor 226, an electric control valve 227 and a feeding MCU 228, wherein the pressure sensor 226 is mounted on the push plate 223, the electric control valve 227 is mounted at the outlet of the furnace side silo 21, and the feeding MCU 228 is electrically connected to the pressure sensor 226 and the electric control valve 227;

[0090] The feeding MCU 228 stores the feeding threshold and feeding duration, and the pressure sensor 226 sends the detected pushing pressure value to the feeding MCU 228. When the pushing pressure value is lower than the feeding threshold, the feeding MCU 228 sends the door opening signal to the electric control valve 227. After the feeding duration, the feeding MCU 228 sends the door closing signal to the electric control valve 227. The beneficial effect of this technical solution is that when the pushing plate 223 pushes the glass bottle raw material 6 forward, the pressure sensor 226 detects the force given by the glass bottle raw material 6, and when the pushing plate 223 moves backward, the pressure signal detected by the pressure sensor 226 is invalid. When the push plate 223 moves forward, but the pressure value detected by the pressure sensor 226 is lower than the feeding threshold, it means that there is no glass bottle raw material 6 in the feeding chamber. At this time, the MCU 228 for feeding opens the electric control valve 227 of the furnace side silo 21, and the glass bottle raw material 6 falls from the furnace side silo 21 to the feeding chamber 2211. After the feeding duration, for example, two seconds, the electric control valve 227 is closed. Avoid excessive glass bottle raw materials 6 in the feeding chamber 2211, which interferes with the work of the push plate 223. The feeding threshold can be set to zero, or the actual production situation can be considered, such as the pressure exerted on the push plate 223 by the hot air emitted by the kiln 23, and the feeding threshold is set to be slightly greater than zero. In this way, the glass bottle raw materials 6 are automatically added to the feeding chamber 2211 step by step and in an orderly manner.

[0091] The working mode of the present invention is as follows: the main material, auxiliary material and smoke recovery byproducts of the glass bottle are all pre-proportioned, weighed and transported to the mixer 142 for stirring and mixing. In the process of the mixed material 144 being transported to the furnace side silo 21, the broken glass 154 is gradually and evenly spread on the top of the mixed material 144, and then mixed in the furnace side silo 21, and then falls into the feeding chamber 2211 of the feeder 22, and is pushed into the kiln 23. The glass bottle raw material 6 passes through the high temperature of the kiln 23 and becomes a molten liquid, and smoke is generated at the same time, which flows from the smoke outlet of the kiln 23 to the smoke inlet 31 of the desulfurization and denitration equipment 3. After the smoke is desulfurized and denitrated, the gas that meets the requirements is discharged to the atmosphere through the chimney, and the byproducts generated by the desulfurization and denitration equipment 3 are recycled. Automatic proportioning and weighing improves efficiency, reduces environmental pollution, and saves the cost of glass bottle raw materials.

Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
