Description

Technical Field

[0001] The invention relates to the technical field of solar vacuum heat collecting tube production, in particular to an electric furnace feeder for solar vacuum heat collecting tube production. Background Art

[0002] The electric furnace feeder for the production of solar vacuum collector tubes is a kind of equipment specially used in the production process of solar vacuum collector tubes. The electric furnace feeder for the production of solar vacuum collector tubes is mainly used to feed materials into the electric furnace evenly and continuously for melting, so as to produce glass tubes or other materials required for solar vacuum collector tubes.

[0003] After searching, the Chinese patent with announcement number CN207659301U discloses a belt feeding device and a mutually feeding float glass production line group, the belt feeding device includes a T-shaped bracket, a driving wheel, a first driving motor, a conveyor belt and two driven wheels, the two driven wheels are rotatably arranged at the opposite ends of the T-shaped bracket, the driving wheel is arranged between the two driven wheels and is rotatably connected to the T-shaped bracket, the first driving motor is fixed on the T-shaped bracket, and the driving shaft of the first driving motor is fixedly connected to the driving wheel to drive the driving wheel to rotate, the conveyor belt is wound between the two driven wheels and the driving wheel, when the feeding device of a float glass production line fails and cannot transport glass raw materials to the kiln head silo, the belt feeding device is wound with one end of the conveyor belt and can extend into the kiln head silo of another production line and take the glass raw materials away and transport them to the kiln head silo of the previous float glass production line, but the above scheme still has the following shortcomings when it is actually used: The above scheme uses a belt feeding method to feed the glass raw materials. Although it can realize automatic feeding to a certain extent and improve production efficiency, the belt feeding method occupies a large space, which will have the following disadvantages: First, the large space occupied means that more space needs to be reserved in the production workshop to place the electric furnace feeder, which may lead to the overall layout of the production workshop being restricted, affecting the layout of other equipment and the optimization of the production process. Especially in a production environment with limited space, the belt feeding method may become a bottleneck restricting the improvement of production efficiency. Secondly, the belt feeding method may also bring inconvenience to material handling and transportation while occupying a large amount of space. Since the belt feeder is usually long, the material needs to pass through a long path during the transportation process, which increases the risk of material loss and pollution during the transportation process. At the same time, the maintenance and management of the belt feeder is relatively complicated, and the belt needs to be regularly inspected and replaced, which increases the production cost and maintenance workload. In addition, the belt feeding method may also bring problems such as noise and dust pollution. The belt will generate certain noise during operation, which will interfere with the production environment. At the same time, the glass raw materials may generate dust during the transportation process, which will threaten the health of production workers and the cleanliness of the production environment.

[0016] Beneficial effects of the present invention: 1. By adopting the design of two feeding hoppers moving alternately on the fixed frame and feeding automatically, the uninterrupted supply of sand and gravel raw materials is realized. During the feeding process of the device, one feeding hopper is located directly above the guide hopper for feeding, and the other feeding hopper is located at the other end of the fixed frame, which is convenient for the staff to put sand and gravel raw materials into it. This alternating feeding method not only ensures the feeding efficiency, but also significantly reduces the space occupied by the device. Compared with the traditional belt conveyor feeding method, it has the advantages of being more compact and efficient. In summary, the present invention effectively improves the continuity of the feeding operation and the space utilization rate; 2. When the second motor is started, it will drive the rotating shaft 1 to rotate, and then transmit power through the meshing gear 1 and gear 2, so that the rotating shaft 2 will also rotate synchronously. During the rotation of the rotating shaft 2, the multiple stirring rods installed on it will rotate accordingly. These stirring rods can effectively stir the sand and gravel raw materials in the inner tank, significantly improving the fluidity of the sand and gravel raw materials. This stirring effect is not only conducive to the smooth fall of the sand and gravel raw materials from the inner tank, but also effectively prevents the sand and gravel raw materials from being stuck inside the inner tank due to accumulation or friction, thereby ensuring the continuity and stability of the feeding; 3. When the rotating shaft 1 rotates, it not only drives the stirring structure to work, but also cleverly drives the eccentric wheel to rotate. During the rotation process, the eccentric wheel continuously applies pressure to the connecting frame, causing the connecting frame and the inner tank connected thereto to vibrate. This vibration greatly enhances the fluidity of the sand and gravel raw materials in the inner tank, making it easier and smoother for the sand and gravel raw materials to fall from the inner tank, thereby significantly improving the discharge efficiency. At the same time, when the inner tank vibrates, the two mounting rods slide in the two through-holes to achieve stable limiting, preventing excessive shaking of the inner tank and ensuring the stability and reliability of the entire feeding process; 4. When the slider moves back and forth in the mounting tube, it stretches and compresses the airbag respectively, and the two air pipes and the one-way valves arranged on the airbag ensure the unidirectional flow of gas: one one-way valve allows gas to enter the airbag, and the other allows gas to be discharged from the airbag. This mechanism enables the airbag to perform a vacuum action when stretched, extracting the gas in the annular tube, and the dust suction port on the annular tube is responsible for absorbing the dust generated during the discharge process. When the airbag is compressed, it performs an exhaust action to discharge the collected dust into the dust collecting box. By providing two suction parts, the present invention ensures that the dust suction port on the annular tube can perform a vacuum action alternately, thereby avoiding the window period in the dust suction action and ensuring the continuous and efficient absorption of dust by the device. This design not only effectively reduces dust pollution in the production environment, but also improves the cleanliness and safety of the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0022] like Figures 1 to 11 As shown, the electric furnace feeder for producing solar vacuum collector tubes includes an electric melting furnace 1; a guide hopper 2, which is fixed on the electric melting furnace 1 and arranged directly opposite to the feed port of the electric melting furnace 1; a fixing frame 3, which is placed on one side of the electric melting furnace 1, one end of the fixing frame 3 is fixed on the electric melting furnace 1, and the fixing frame 3 is arranged in an inclined manner as a whole; two feeding hoppers 4, which are both arranged on the fixing frame 3, the top of the feeding hopper 4 is open, and a discharge pipe is arranged at the bottom, and an electromagnetic discharge valve is installed on the discharge pipe; two inner tanks 5, which are respectively placed inside the two feeding hoppers 4; two mounting frames 6, which are respectively fixed on the tops of the two feeding hoppers 4; When the electric furnace feeder for producing solar vacuum collector tubes proposed in the present invention is in use, in the initial state, one of the feeding hoppers 4 is located at the high point end of the fixed frame 3, and the other feeding hopper 4 is located at the low point end of the fixed frame 3. The discharge pipe on the feeding hopper 4 located at the high point end of the fixed frame 3 is arranged directly opposite to the guide hopper 2. When the feeding hopper 4 moves to a position directly opposite to the guide hopper 2, the electromagnetic discharge valve is opened. At this time, the sand and gravel raw materials in the inner tank 5 will fall through the discharge pipe and fall into the interior of the guide hopper 2, thereby realizing automatic feeding of the sand and gravel raw materials. When the raw materials are put in, the feeding hopper 4 above the guide hopper 2 moves downward along the fixed frame 3. In this process, the other feeding hopper 4 will move along the fixed frame 3. The fixed frame 3 moves upward and moves to the top of the guide hopper 2. When the feeding hopper 4 moves to the top of the guide hopper 2, the feeding hopper 4 automatically feeds. When one of the feeding hoppers 4 is located above the guide hopper 2, the other feeding hopper 4 is located at the end of the fixed frame 3 away from the guide hopper 2. Based on the above process, when one of the feeding hoppers 4 is feeding, the staff can put sand and gravel raw materials into the other feeding hopper 4. The device uses two feeding hoppers 4 to feed alternately, realizing uninterrupted feeding of raw materials. This feeding method replaces the traditional belt conveyor feeding method. On the basis of ensuring feeding efficiency, it significantly reduces the space occupied by the device; like Figure 1 , Figure 2 As shown, the electric furnace feeder also includes a driving structure, which is arranged on the fixed frame 3, and the driving structure includes: two rollers 81, which are rotatably mounted on the two ends of the fixed frame 3 respectively; a transmission belt 82, which is sleeved on the two rollers 81, and the two rollers 81 are connected to each other through the transmission belt 82; a first motor 83, which is installed on the fixed frame 3, and the output shaft of the first motor 83 is fixedly connected to one of the rollers 81; two sleeve plates 84, which are both fixedly sleeved on the transmission belt 82, and the two sleeve plates 84 are fixedly connected to the two feeding hoppers 4 respectively; The two feeding hoppers 4 are moved on the fixed frame 3 through the driving structure. Specifically, the first motor 83 is started and drives the corresponding roller 81 to rotate. The rotating roller 81 cooperates with another roller 81 to drive the transmission belt 82 to rotate. When the transmission belt 82 rotates, it can drive the two sleeves 84 to move. When one sleeve 84 moves obliquely upward, the other sleeve 84 moves obliquely downward, so that the two feeding hoppers 4 can be moved alternately to the top of the guide hopper 2. like Figure 7 , Figure 8 As shown, the electric furnace feeder also includes two guide structures, both of which are arranged on the fixed frame 3, and the guide structures include: two connecting rods 91, respectively fixed at the two ends of the fixed frame 3; a guide plate 92, fixed at one end of the two connecting rods 91 away from the fixed frame 3; a guide opening 93, opened on the guide plate 92, and arranged along the length direction of the guide plate 92; a guide block 94, fixed on the feeding hopper 4, and the guide block 94 slides in the guide opening 93; two limit plates 95, both fixedly sleeved on the guide block 94, and the two limit plates 95 are respectively placed on both sides of the guide plate 92; When the feeding hopper 4 is moving, the guide block 94 will move accordingly and slide in the guide opening 93. The guide opening 93 and the guide block 94 guide the movement of the feeding hopper 4 to ensure the stability of the feeding hopper 4 during movement. In addition, two limit plates 95 are fixed on the guide block 94, and the two limit plates 95 are respectively located on both sides of the guide plate 92. The side surfaces of the two limit plates 95 are in contact with the side surfaces of the guide plate 92. The setting of the two limit plates 95 can prevent the guide block 94 from shaking during movement, thereby further improving the stability of the feeding hopper 4 during movement. like Figure 5 , Figure 6As shown, the two inner tanks 5 are connected to the corresponding feeding hoppers 4 through a connecting structure, and the connecting structure includes: two through-holes, both of which are opened on the feeding hopper 4, and the two through-holes are arranged opposite to each other; two mounting rods 71, both of which are fixed on the inner tank 5, and the ends of the two mounting rods 71 ​​that are away from each other pass through the two through-holes respectively and extend to the outside of the feeding hopper 4; two limit plates 72, respectively fixed to the ends of the two mounting rods 71 ​​that are away from each other; two springs 73, one end of which is connected to the feeding hopper 4, and the other end is connected to the two limit plates 72 respectively; When the inner liner 5 vibrates, the fluidity of the sand and gravel materials in the inner liner 5 is further improved, which is more conducive to the sand and gravel materials falling from the inner liner 5 and improving the discharge efficiency. In addition, during the vibration of the inner liner 5, the two mounting rods 71 ​​will slide in the two through-holes, and the two mounting rods 71 ​​play a role in limiting the vibration of the inner liner 5. The two springs 73 arranged between the two limiting plates 72 and the feeding hopper 4 provide support for the vibration of the feeding hopper 4. like Figure 5 , Fig. 9 and Fig.11 As shown, the two mounting frames 6 are provided with a stirring structure and a vibration structure, and the stirring structure includes: a second motor 101, mounted on the mounting frame 6; a rotating shaft 102, rotatably mounted on the mounting frame 6; a rotating shaft 103, rotatably mounted on the mounting frame 6; a gear 104, fixedly sleeved on the rotating shaft 102; a gear 2 105, fixedly sleeved on the rotating shaft 2 103, and the gear 104 and the gear 2 105 are meshed with each other; a plurality of stirring rods 106, all fixed at the bottom end of the rotating shaft 2 103, and each stirring rod 106 is placed inside the inner liner 5, and the vibration structure includes: an eccentric wheel 111, fixed at the bottom end of the rotating shaft 102, and eccentrically arranged between the eccentric wheel 111 and the rotating shaft 102; a connecting frame 112, fixed at the top end of the inner liner 5, and the connecting frame 112 extends from one end of the inner liner 5 to the outside of the feeding hopper 4, and the eccentric wheel 111 is arranged opposite to the connecting frame 112; Both feeding hoppers 4 are provided with stirring structures. Specifically, during the discharging process of the feeding hopper 4, the second motor 101 is started and drives the rotating shaft 102 to rotate. When the rotating shaft 102 rotates, it can drive the rotating shaft 2 103 to rotate through the mutually meshing gear 104 and the gear 2 105. During the rotation of the rotating shaft 2 103, a plurality of stirring rods 106 thereon will rotate accordingly. The plurality of rotating stirring rods 106 can stir the sand and gravel raw materials in the inner liner 5 to improve the fluidity of the sand and gravel raw materials. This design is conducive to the sand and gravel raw materials falling from the inner liner 5 and preventing the sand and gravel raw materials from being stuck inside the inner liner 5. When the rotating shaft 102 rotates, it can also drive the eccentric wheel 111 to rotate. When the eccentric wheel 111 rotates, it will continuously squeeze the connecting frame 112, so that the connecting frame 112 produces a vibration effect. When the connecting frame 112 vibrates, it can drive the inner liner 5 to vibrate. like Figure 6 As shown, the two feeding hoppers 4 are provided with a dust collecting structure; the dust collecting structure comprises: a plurality of vertical rods 121, all fixed at the bottom end of the feeding hopper 4; an annular tube 122, fixed at one end of the plurality of vertical rods 121 away from the feeding hopper 4, the annular tube 122 being sleeved on the discharge pipe at the bottom of the feeding hopper 4; a plurality of dust collecting ports 123, all opened on the annular tube 122; a dust collecting box 124, mounted on the mounting frame 6; like Figures 6 to 11 As shown, the two mounting frames 6 are both provided with an exhaust structure, and the exhaust structure includes a driving member and an air suction member, and the driving member includes: two brackets 131, both fixed on the mounting frame 6; a reciprocating screw rod 132, rotatably mounted between the two brackets 131; a moving frame 133, threadedly sleeved on the reciprocating screw rod 132; a transmission shaft 134, fixed at one end of the reciprocating screw rod 132; two bevel gears 135, one of which is fixedly sleeved on the top of the rotating shaft 103, and the other is fixedly sleeved on the transmission shaft 134, and the two bevel gears 135 are meshed with each other, and the air suction member includes: a mounting cylinder 141, which is placed directly above the mounting frame 6; two support rods 142, respectively fixed at both ends of the mounting cylinder 141, and the ends of the two support rods 142 away from the mounting cylinder 141 are respectively fixedly connected to the two brackets 131; a slider 143, which is slidably arranged on the mounting cylinder The interior of 141; the strip opening 144 is opened on the mounting tube 141 and is arranged along the axial direction of the mounting tube 141; the fixing rod 145 is fixedly connected to the movable frame 133 at one end and fixedly connected to the slider 143 at the other end, and the fixing rod 145 slides in the strip opening 144; two suction parts are both arranged inside the mounting tube 141, and the two suction parts are respectively arranged on both sides of the slider 143, and the suction part includes: an air bag 146, one end of which is connected to the inner surface of the mounting tube 141, and the other end is connected to the slider 143; two air pipes 147 are both connected to the air bag 146, one end of the air pipe 147 away from the air bag 146 is connected to the annular tube 122, and the other end of the air pipe 147 away from the air bag 146 is connected to the dust box 124; two one-way valves 148 are respectively installed on the two air pipes 147, and the limiting directions of the two one-way valves 148 are opposite; The two feeding hoppers 4 are both provided with a dust suction function, which is used to absorb the dust generated during the discharge process to prevent the dust from flying around. Specifically, when the rotating shaft 103 rotates, it can drive the transmission shaft 134 to rotate through two mutually meshing bevel gears 135. When the transmission shaft 134 rotates, it can drive the reciprocating screw rod 132 to rotate. Since the bottom surface of the moving frame 133 and the top surface of the mounting frame 6 are in contact with each other, the moving frame 133 cannot rotate with the reciprocating screw rod 132, but will rotate between the two brackets under the rotation of the reciprocating screw rod 132. 131, the movable frame 133 can move back and forth through the fixed rod 145, so that the slider 143 moves back and forth inside the mounting tube 141. When the slider 143 moves back and forth, the two suction parts will operate alternately. For the suction part, when the slider 143 moves toward one end of the mounting tube 141, the slider 143 can stretch the airbag 146, and when the slider 143 moves toward the other end of the mounting tube 141, the slider 143 can compress the airbag 146. Two air pipes 147 are provided, and one-way valves 148 are installed on both air pipes 147. The flow limiting directions of the two one-way valves 148 are opposite. Specifically, one of the one-way valves 148 limits the gas to only enter the interior of the airbag 146, and the other one-way valve 148 limits the gas to only flow out of the airbag 146. Therefore, when the airbag 146 is stretched, the airbag 146 can perform a pumping action, and when the airbag 146 is compressed, the airbag 146 can perform a deflation action. Based on the above process, the slider 143 moves back and forth. During the process, the airbag 146 can extract the gas in the annular tube 122, which enables the several dust suction ports 123 on the annular tube 122 to absorb the dust generated during the discharge process. Furthermore, the dust will be discharged into the interior of the dust collecting box 124 when the airbag 146 is compressed, thereby collecting the dust. What is meant is that by setting two suction parts, the several dust suction ports 123 on the annular tube 122 can perform the suction action alternately, avoiding the window period of the dust suction action, and ensuring the dust absorption effect of the device.
