Description

[0002] In the glass melting production process, materials need to be put into the kiln for processing; in order to put different materials into the kiln at the same time according to a certain ratio, a feeder is often used for feeding operations.

[0003] The overall structure of the commonly used glass melting feeder is fixed. Considering that the operating state of the motor and vibrator in the feeder will cause the entire device to vibrate, in order to avoid the collision between the discharge port of the feeder and the feed port of the kiln and thus damage to the equipment, the feeder mostly adopts non-contact feeding. However, this will cause a certain gap between the discharge port of the feeder and the feed port of the kiln. In the process of continuous feeding, since the motor and vibrator inside the feeder will carry the airflow synchronously during the material conveying process, the airflow will surge out from the gap between the feeder and the kiln, which will cause the material to fly and the dust to be scattered; in addition, the processing operation in the kiln will also cause the air pressure in the gap to become chaotic, further aggravating the problem of flying materials in the gap, directly leading to increased production costs, reduced input-output ratio, and a significant increase in the cost of waste material disposal.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides a novel glass melting continuous feeding equipment. Figure 1 FIG. 1 is a schematic front view of a novel glass melting and continuous feeding device in an embodiment of the present invention, referring to FIG. Figure 1 , Figure 2 and Figure 3 The novel glass melting continuous feeding equipment comprises: a platform frame 1 and a powder material feeding device 2, a return material feeding device 3, and a material collecting component 4 installed on the platform frame 1. The material collecting component 4 comprises an outer casing 41, an inner casing 42, a powder material feeding pipe 43, a return material feeding pipe 44, and an air pressure connecting pipe 45;

[0037] The outer shell 41 has a gas pressure cavity inside, and a connection port 46 for connecting to the kiln is opened at the lower end of the outer shell 41. The inner sleeve 42 is built into the gas pressure cavity, one end of the inner sleeve 42 faces the connection port 46, and the other end of the inner sleeve 42 maintains a predetermined distance from the inner wall of the outer shell 41;

[0038] One end of the return material feed pipe 44 and the powder material feed pipe 43 penetrates the side wall of the outer casing 41 and extends to communicate with the inner cavity of the inner casing 42, and the other ends of the return material feed pipe 44 and the powder material feed pipe 43 are connected to the output ends of the powder material feeding device 2 and the return material feeding device 3 respectively;

[0039] The air pressure connecting pipe 45 penetrates through the side wall of the outer shell 41 and connects the air pressure cavity with the external environment.

[0040] Among them, the surfaces of the powder feeding device 2, the re-furnace feeding device 3, and the material collecting component 4 are all coated with a protective coating. The raw materials of the protective coating are selected from materials with good chemical stability, corrosion resistance, oxidation resistance, and not easy to contaminate the glass raw materials, including but not limited to ceramics, aluminum or its alloy materials or its oxide coating, plastic, etc., to avoid chemical reactions between the materials and the powder and affect the product quality.

[0041] At the same time, the powder feeding device 2, the re-furnace feeding device 3, and the material collecting component 4 can also be made entirely of ceramic, aluminum, or plastic materials to avoid the problem of chemical reaction between the material and the powder.

[0042] During actual use, the powder feeding device 2 and the return furnace feeding device 3 are started, and the powder feeding device 2 drives the powder to flow out from the output end, and is transported to the inner cavity of the inner sleeve 42 through the powder feeding pipe 43; at the same time, the return furnace feeding device 3 drives the return furnace material to flow out from the output end, and is transported to the inner cavity of the inner sleeve 42 through the return furnace material feeding pipe 44, so that the return furnace material and the powder are mixed in the inner cavity of the inner sleeve 42, and are transported to the stove from the connecting port 46.

[0043] During this material conveying process, the powder feeding device 2 and the re-furnace feeding device 3 will synchronously convey gas into the inner sleeve 42, causing the air pressure in the inner cavity of the inner sleeve 42 to increase; in this embodiment, on the basis that one end of the inner sleeve 42 is facing the connecting port 46 and the other end of the inner sleeve 42 maintains a predetermined distance from the inner wall of the outer sleeve 41, the gas in the inner sleeve 42 can flow directly from the upper and lower ends of the inner sleeve 42 to the air pressure cavity of the outer sleeve 41, and then flow to the external environment through the air pressure connecting pipe 45, and at the same time, it is used to release excessive air pressure in the kiln, maintain the stability of the air pressure in the kiln, realize the evacuation of airflow and ensure air pressure balance, avoid the problem of material flying due to airflow movement, and ensure the safety and efficiency of the production process.

[0044] refer to Figure 4The powder feeding device 2 includes: a first weighing device 21, a powder material box 22, a first screw shaft 23, and a first servo motor 24;

[0045] The first weighing device 21 is installed on the platform frame 1, and the powder material box 22 is installed on the bearing surface of the first weighing device 21. Figure 4 In the example shown, there are four first weighing devices 21, and the bearing surfaces of the four first weighing devices 21 correspond to the four legs on the powder material box 22, respectively. The four first weighing devices 21 are used to measure the overall weight of the powder material box 22 at all times.

[0046] The top of the powder material box 22 is detachably fastened with a first hatch 25, the lower end of the inner cavity of the powder material box 22 is rotatably mounted with a first screw shaft 23, a side wall of the powder material box 22 is provided with a material box outlet corresponding to the first screw shaft 23, and a transfer tube 26 for connecting to the powder material feed pipe 43 is installed at the material box outlet;

[0047] One end of the first screw shaft 23 is connected to the first servo motor 24, and the other end of the first screw shaft 23 extends into the inner cavity of the transfer tube 26, so that the propeller blade of the first screw shaft 23 blocks the outlet of the material box to prevent the gas from flowing in the opposite direction.

[0048] Before using the powder feeding device 2, open the first hatch 25 and put the prepared powder into the powder box 22; after starting the powder feeding device 2, the four first weighing devices 21 collect the weight of the entire powder box 22 in real time, and then obtain the specific weight of the powder in the inner cavity of the powder box 22; at the same time, start the first servo motor 24 to start rapid rotation and drive the first screw shaft 23 to work, so as to push the powder to be continuously transported from the transfer tube 26 to the powder feed pipe 43, and through the detected weight value of the powder box 22, the efficiency of the first screw shaft 23 outputting the powder is controlled accordingly, so as to realize the integrity of the operation of the powder feeding device 2.

[0049] refer to Figure 5 A second spiral shaft 5 is rotatably installed in the inner cavity of the powder feed pipe 43, one end of the second spiral shaft 5 is transmission-connected to the second servo motor 6, and the other end of the second spiral shaft 5 extends to the inner cavity of the inner sleeve 42. When the powder feeding device 2 conveys the powder into the powder feed pipe 43, the second servo motor 6 is started to drive the second spiral shaft 5 to rotate, and the powder is further conveyed to the inner cavity of the inner sleeve 42.

[0050] It should be noted that, in actual use, the second servo motor 6 drives the second screw shaft 5 at a constant speed, so that the amount of powder transported by the powder feed pipe 43 to the inner cavity of the inner sleeve 42 per unit time remains constant, thereby ensuring the stability and continuity of the feeding process, improving production efficiency and reducing product quality fluctuations that may be caused by unstable feeding.

[0051] exist Figure 4 In the example shown, the powder box 22 and the powder feed pipe 43 are arranged in upper and lower positions. A connecting end pipe 47 connected to the inner cavity of the powder feed pipe 43 is provided on the side wall of one end of the powder feed pipe 43 away from the outer shell 41. The connecting end pipe 47 is connected to the transfer pipe 26 through a hose 7.

[0052] On the basis of using the hose 7 to connect, the powder feed pipe 43 and the powder feeding device 2 form two relatively independent devices, that is, the shaking of the powder feed pipe 43 and the shaking of the powder feeding device 2 will not affect each other, thereby ensuring the accuracy of the first weighing device 21 in measuring the weight of the powder box 22. At the same time, the hose 7 connection also effectively prevents the problem of dust being thrown between the two-stage spiral devices, further improving the utilization rate of the powder and reducing the production cost and waste disposal cost.

[0053] In actual use, the glass melting powder is first loaded into the powder feeding box 22, and the first screw shaft 23 is started according to preset parameters. The powder is accurately weighed by adjusting the rotation speed and rotation time of the first screw shaft 23.

[0054] After weighing, the first spiral shaft 23 pushes the powder to the powder feed pipe 43. Since the two are connected by a hose 7, the hose 7 is sealed with a 0.3 mm resin material to avoid dust leakage during the powder transfer process. The second spiral shaft 5 then pushes the powder to the inner cavity of the inner sleeve 42. During the pushing process, due to the sealing design, the dust is effectively confined inside the powder feed pipe 43, greatly reducing the dust scattering phenomenon. In addition, the first spiral shaft 23 and the second spiral shaft 5 prevent the reverse flow of the airflow in the inner cavity of the inner sleeve 42, and prevent the airflow from flowing back to the powder box 22, causing the first weighing device 21 to weigh inaccurate data.

[0055] exist Figure 6 In the example shown, the recycled material feeding pipe 44 includes a tube body 441 and an interface 442, the first end of the tube body 441 is connected to the inner sleeve 42, the second end of the tube body 441 is higher than the first end of the tube body 441, the second end of the tube body 441 is connected to the interface 442 for docking the output end of the recycled material feeding device 3, and the interface 442 adopts a flared structure to facilitate receiving the recycled material. At the same time, the height of the first end of the tube body 441 is lower than the second end of the tube body 441, so that the recycled material actively flows from the second end of the tube body 441 to the first end of the tube body 441 under the action of its own gravity until it enters the inner cavity of the inner sleeve 42, and the problem of the recycled material gathering at the second end of the tube body 441 will not occur.

[0056] Corresponding, reference Figure 7 and Figure 8The re-melting material feeding device 3 includes a second weighing device 31, a re-melting material box 32, a guide groove 33 and an electric vibrator 34;

[0057] The second weighing device 31 is installed on the platform frame 1, and the return material box 32 is installed on the bearing surface of the second weighing device 31. The top of the return material box 32 can be detachably buckled with the second hatch 35. The lower end of the return material box 32 is provided with a discharge port, and the guide groove 33 is located below the return material box 32. The guide groove 33 is located below the return material box 32. One end of the guide groove 33 is connected to the discharge port, and the other end of the guide groove 33 is provided with a notch for connecting with the return material feed pipe 44; Figure 6 In the example shown, the lower end of the return material box 32 adopts a flared structure with a larger upper portion and a smaller lower portion, and the discharge port is extended into the inner cavity of the guide groove 33, and the discharge port is spaced 30 mm to 50 mm from the inner bottom surface of the guide groove 33, so as to avoid the problem that the return material cannot be effectively advanced due to the contact between the return material box 32 and the guide groove 33;

[0058] Correspondingly, by opening the discharge port, the recycled materials in the recycled material box 32 naturally fall into the guide groove 33; at the same time, the number of second weighing devices 31 is four, and the bearing surfaces of the four second weighing devices 31 respectively correspond to the four legs on the recycled material box 32, and the four second weighing devices 31 are used to measure the overall weight of the recycled material box 32.

[0059] At the same time, in order to ensure that the recycled materials in the guide groove 33 are transported from the guide groove 33 to the recycled material feeding pipe 44 in an orderly manner, an electric vibrator 34 is installed on the side wall of the guide groove 33, and a notch is opened at one end of the guide groove 33 that is connected to the recycled material feeding pipe 44.

[0060] In actual use, the prepared return material powder is added to the return material box 32 from the feeding port, the return material feeding device 3 is started, and the second weighing device 31 is used to collect the current weight of the entire return material box 32 in real time. The electric vibrator 34 is started to drive the guide groove 33 to vibrate back and forth, and on the basis of the inclined arrangement of the guide groove 33, the return material is guided to flow through the guide groove 33 to the return material feeding pipe 44 in an orderly manner, thereby ensuring the quantitative and regular output of the return material. When the weight of the return material reaches the set value, the electric vibrator 34 stops working, accurately controlling the feeding amount of the return material, ensuring the accuracy and stability of the return material added to the production process, and helping to improve the controllability and product quality of the entire glass melting production process.

[0061] exist Figure 6 In the example shown, the first end of the air pressure connecting tube 45 connected to the outer shell 41 maintains a predetermined height difference with the connecting port 46 to prevent the material delivered from the connecting port 46 from directly overflowing into the air pressure connecting tube 45 .

[0062] At the same time, the second end of the air pressure connecting tube 45 is higher than the first end of the air pressure connecting tube 45, so that the air pressure connecting tube 45 is in an upward shape. During the flow of the airflow, a small amount of material dust will be carried to move synchronously. Through the height difference and the upward shape of the air pressure connecting tube 45, the airflow will show an upward trend after flowing out from the lower end of the inner cavity of the inner sleeve 42, thereby allowing the material that may be carried in the airflow to fall naturally under the action of its own gravity, thereby reducing the volume of material carried by the airflow;

[0063] In addition, a ventilation cover plate 8 is installed at the second end of the air pressure connecting pipe 45 to further block the material in the air flow and further reduce the volume of the material flying. At the same time, the air pressure in the kiln is maintained stable to ensure the safety and efficiency of the production process.

[0064] In this embodiment, the outer shell 41 includes an outer shell body 411 and an end cover 412. The upper end of the end cover 412 is detachably fastened to the end of the outer shell body 411, and a connection port 46 is provided at the lower end of the end cover 412. The outer shell body 411 is sealed and connected to the kiln through the connection port 46, which effectively prevents material leakage and abnormal fluctuations in air pressure in the kiln. During the production process, the end cover 412 is opened to observe the inner cavity of the outer shell body 411, so as to check the chemical state in the kiln and adjust the production parameters in time according to actual conditions.

[0065] The platform frame 1 of the present invention comprises a bracket 11, a roller 9 rolling along a first direction is installed at the lower end of the bracket 11, a first end plate 12 and a second end plate 13 are symmetrically arranged on the upper end surface of the bracket 11, the upper end surfaces of the first end plate 12 and the second end plate 13 are commonly connected to a slide rail 14, a slide platform 15 is slidably installed on the slide rail 14 along a second direction, and the slide platform 15 is installed to carry and install a powder feeding device 2, a re-furnace feeding device 3, and a material collecting component 4;

[0066] The first direction is arranged perpendicular to the second direction.

[0067] In this embodiment, the bracket 11 is made of welded square tubes and has good structural strength. In order to ensure the safety of the device during use, a guardrail is welded around the sliding platform 15.

[0068] When docking with the kiln, the position adjustment in the first direction can be easily achieved by pushing the platform frame 1, ensuring the precise docking of the equipment with the kiln feed port in the first direction. The position of the sliding platform 15 above the base of the platform frame 1 in the second direction can achieve precise alignment between the connection port 46 of the material collecting component 4 and the kiln.

[0069] According to calculations, the powder utilization rate of traditional feeders is only between 90% and 92% due to the flying of materials, of which 8% to 10% of the powder will become waste, which not only reduces the input-output ratio, but also greatly increases the cost of waste material treatment. The feeding equipment in this embodiment, under the combination of the first weighing device 21, the second weighing device 31, the first screw shaft 23, the second screw shaft 5, and the electric vibrator 34, realizes the precise control of the material conveying volume and conveying efficiency, thereby achieving the purpose of constant feeding to the kiln, ensuring the stability and continuity of the feeding process; at the same time, under sealed conditions, the utilization rate of glass melting powder can be increased to more than 95%, effectively solving many problems existing in traditional feeders, and having significant economic and environmental benefits.
