Description

Technical Field

[0001] This utility model relates to an automatic feeding machine for producing airtight sand in a kiln, belonging to the technical field of feeding mechanisms. Background Technology

[0002] An automatic feeder for closed-loop sand production in kilns is an automated device used in the closed-loop sand production process. It is specifically designed to supply materials to kilns. In cement production, kilns require a large amount of raw materials such as quartz sand to adjust the composition and properties of cement. The automatic feeder can provide a stable supply of quartz sand to the kiln, ensuring the stability of cement quality. At the same time, in kilns producing ceramic bricks, sanitary ware, and other ceramic products, it is also necessary to accurately supply ceramic raw material sand to ensure the dimensional accuracy, surface quality, and physical properties of ceramic products.

[0003] A Chinese patent (CN215855753U) discloses an electric kiln feeding device, belonging to the field of glass manufacturing technology. It includes: a feeding hopper; and a hollow water-cooled jacket connected to the outlet of the feeding hopper via an insulating connection mechanism, with the outlet end of the water-cooled jacket extending into the inlet of the electric kiln. In this electric kiln feeding device, the electric kiln is insulated from the external feeding hopper, preventing the formation of a circuit between the electric kiln and the feeding hopper. This avoids fluctuations in the production process caused by induced current within the electric kiln, thus improving production safety.

[0004] When an automatic feeder for closed-loop sand production in a kiln generates material into individual material frames, it can create a dust risk. This dust may contain fine sand particles, dust, and other particulate matter. When operators inhale this dust, it can irritate their respiratory mucosa. Long-term exposure to dusty environments may lead to respiratory diseases such as chronic bronchitis and emphysema.

[0005] Therefore, an automatic feeding machine for producing sand in a kiln with a closed temperature range is proposed. Utility Model Content

[0006] In view of this, the present invention provides an automatic feeding machine for the production of sealed sand in a kiln, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: An automatic feeding machine for producing sealed sand in a kiln includes a feeding tank. An outer upper circular plate is fixedly connected to the lower end of the feeding tank. A corrugated stretching pipe is fixedly connected to the lower end of the outer upper circular plate. An outer lower circular plate is fixedly connected to the lower end of the corrugated stretching pipe. An electric push rod is fixedly connected to each of the four corners of the upper end of the outer lower circular plate. The output end of the electric push rod is connected to the outer upper circular plate. An electric conveyor belt is provided at the lower end of the feeding tank. A plurality of ring-shaped limiting components are provided at the inner end of the outer lower circular plate. Each limiting component includes an electric push rod fixedly connected to the inner wall of the outer lower circular plate. A limiting inner block is fixedly connected to the output end of the electric push rod. A contact sensor is provided at the end of the limiting inner block away from the electric push rod. A plurality of horizontally equidistant hollow material distribution frames are placed at the upper end of the electric conveyor belt.

[0008] More preferably, the material distribution hollow frame extends directly below the corrugated stretching tube, and multiple limiting components are located around the perimeter of the material distribution hollow frame.

[0009] More preferably, the contact sensor is in contact with the outer wall of the hollow material distribution frame, and a magnetic outer layer is fixedly connected to the outer wall of the electric conveyor belt.

[0010] More preferably, an electromagnetic coil is fixedly connected to the lower end of the outer lower circular plate, and the electromagnetic coil is magnetically connected to the outer layer of the magnetic surface.

[0011] More preferably, the lower end of the feeding tank is symmetrically and fixedly connected with supporting vertical rods on the left and right sides, and the two supporting vertical rods are respectively located on the left and right sides of the electric conveyor belt.

[0012] More preferably, a conical feeding ring is fixedly connected to the lower end of the feeding tank, and the conical feeding ring is located above the corrugated stretching pipe.

[0013] More preferably, the inner end of the feeding tank is filled with a number of sand particles, which extend into the hollow distribution frame.

[0014] More preferably, a control terminal is connected to the outside of the feeding tank, and the control terminal is electrically connected to the contact sensor, electric push rod, and electric push rod via wires.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This solution utilizes corrugated stretch pipes as a protective device to effectively suppress dust dispersion during the feeding process, reducing the chance of operators coming into contact with dust. Simultaneously, when the hollow feeding frame moves to below the outer upper circular plate for feeding operations, the outer lower circular plate can adjust the extension length of the electric push rod based on the diameter of the hollow feeding frame. After adjustment, multiple limiting blocks are positioned around the outer wall of the hollow feeding frame. When below the outer lower circular plate, these limiting blocks can be used to move along the outer wall of the conical feeding ring. During this movement, multiple contact sensors outside the limiting blocks contact the outer wall of the hollow feeding frame. If all four contact sensors receive a normal contact signal, it indicates that the feeding position of the conical feeding ring is accurate. However, if a deviation occurs, some contact sensors may not receive a correct contact signal. In this case, an external control terminal can be used to alert personnel to check for any abnormalities in the position of the conical feeding ring, thus ensuring the feeding effect.

[0017] Second, several magnetic outer layers are set on the surface of the electric conveyor belt. When the outer lower circular plate moves down through the corrugated stretching tube, the outer lower circular plate is magnetically connected to the electromagnetic ring below it through the magnetic outer layer. The feeding tank is energized when the outer lower circular plate moves down and de-energized when it is raised, which makes the enclosure and sealing of the corrugated stretching tube more comprehensive, the dust covering effect is better, and it is less likely to produce leakage points.

[0026] In the following description, only certain exemplary embodiments are briefly described.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, this utility model embodiment provides an automatic feeding machine for producing airtight sand in a kiln, including a feeding tank 1. An outer upper circular plate 3 is fixedly connected to the lower end of the feeding tank 1. A corrugated stretching pipe 4 is fixedly connected to the lower end of the outer upper circular plate 3. An outer lower circular plate 5 is fixedly connected to the lower end of the corrugated stretching pipe 4. Electric push rods 6 are fixedly connected to the four corners of the upper end of the outer lower circular plate 5. The output end of the electric push rod 6 is connected to the outer upper circular plate 3. An electric conveying belt 7 is provided at the lower end of the feeding tank 1. A plurality of ring-shaped limiting components are provided at the inner end of the outer lower circular plate 5. The limiting components include electric push rods 8 fixedly connected to the inner wall of the outer lower circular plate 5. A limiting inner block 9 is fixedly connected to the output end of the electric push rod 8. A contact sensor 10 is provided at the end of the limiting inner block 9 away from the electric push rod 8. A plurality of horizontally equidistant hollow material distribution frames 13 are placed at the upper end of the electric conveying belt 7.

[0030] The material distribution hollow frame 13 extends to the bottom of the corrugated stretching tube 4. Multiple limiting components are located around the material distribution hollow frame 13. The contact sensor 10 is in contact with the outer wall of the material distribution hollow frame 13. Supporting vertical rods 2 are symmetrically fixedly connected to the lower left and right sides of the feeding tank 1. The two supporting vertical rods 2 are located on the left and right sides of the electric conveyor belt 7, respectively. A conical feeding ring 14 is fixedly connected to the lower end of the feeding tank 1. The conical feeding ring 14 is located above the corrugated stretching tube 4. The inner end of the feeding tank 1 is filled with a number of sand particles 15. The sand particles 15 extend into the material distribution hollow frame 13. A control terminal is connected to the outside of the feeding tank 1. The control terminal is electrically connected to the contact sensor 10, the electric push rod 6, and the electric push rod 8 through wires.

[0031] Example 2

[0032] like Figure 2 As shown, in one embodiment, a magnetic outer layer 12 is fixedly connected to the outer wall of the electric conveyor belt 7, and an electromagnetic ring 11 is fixedly connected to the lower end of the outer lower circular plate 5. The electromagnetic ring 11 and the magnetic outer layer 12 are magnetically connected.

[0033] By setting several magnetic outer layers 12 on the surface of the electric conveyor belt 7, the magnetic outer layers 12 can be used to magnetically connect the outer lower circular plate 5 with the electromagnetic ring 11 below it through the magnetic outer layers 12 when the outer lower circular plate 5 moves down through the corrugated stretching tube 4. The feeding tank 1 is energized when the outer lower circular plate 5 moves down and de-energized when it is raised, making the enclosure and sealing of the corrugated stretching tube 4 more comprehensive, the dust covering effect better, and the leakage point less likely to occur.

[0034] In operation, this invention involves: sand particles 15 being collectively filled into the feeding tank 1, and then sequentially outputting them through the outer upper circular plate 3 to the corresponding distribution hollow frame 13 directly below it via an electric valve for subsequent processing. During the feeding process of the feeding tank 1, when the distribution hollow frame 13 moves directly below the output end of the feeding tank 1, the outer lower circular plate 5 is driven by an electric push rod 6 to drop, causing the corrugated stretching tube 4 to stretch and thus completely cover the outer side of the corresponding distribution hollow frame 13. Using the corrugated stretching tube 4 as a protective device effectively suppresses dust dispersion during the feeding process, reducing the opportunity for operators to come into contact with dust, thereby reducing the risk of respiratory and eye diseases and protecting the health of employees. Simultaneously, when the distribution hollow frame 13 moves below the outer upper circular plate 3... When the material feeding operation is performed, the outer lower circular plate 5 can adjust the extension length of the electric push rod 8 by adjusting the diameter of the material distribution hollow frame 13. After adjustment, the multiple limiting blocks 9 are located around the outer wall of the material distribution hollow frame 13. When the material is below the outer lower circular plate 5, the multiple limiting blocks 9 can be used to move at the position of the outer wall of the conical feeding ring 14. During the movement, the multiple contact sensors 10 outside the limiting blocks 9 are in contact with the outer wall of the material distribution hollow frame 13. If all four contact sensors 10 receive the contact signal normally, it means that the feeding position of the conical feeding ring 14 is accurate. If a deviation occurs, some contact sensors 10 will not receive the contact signal correctly. At this time, the external control terminal can be used to remind the staff to check whether there is an abnormality in the position of the conical feeding ring 14, thereby ensuring the feeding effect.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
