Description

Technical Field

[0001] This utility model relates to the field of feeding devices, and in particular to a feeding device for baking in a carbon kiln or jade glaze kiln. Background Technology

[0002] In the firing process of carbon kiln jade glaze kiln, raw materials need to be fed into the kiln through a feeding device. Conventionally, the feeding speed and amount need to be controlled by the experience of workers. However, manual operation is less safe and time-consuming and labor-intensive. Therefore, it is gradually being replaced by mechanical structures, such as vibrating feeders and screw conveyors.

[0003] However, the high internal temperature of the kiln makes the feeding device poorly adaptable to the high-temperature environment. The existing feeding devices for carbon kilns and jade glaze kilns have poor protective effects, and the discharge port is open. The heat in the kiln passes through the opening and directly affects the feeding structure, causing damage and deformation, affecting the amount of material fed. In addition, the high temperature at the discharge port makes the material less fluid during discharge, which can easily cause outlet blockage and make it difficult to control the amount of material fed. Utility Model Content

[0004] In order to overcome the problem that the existing feeding device for baking jade glaze in carbon kiln has poor protection effect and the discharge port is open, the heat in the kiln passes through the opening and directly affects the feeding structure, causing damage and deformation, and affecting the amount of material fed.

[0005] The technical solution of this utility model is as follows: a feeding device for firing in a carbon kiln or jade glaze kiln, including a feeding pipe, a cooling and heat insulation plate, a hopper, a servo motor, and a heat insulation cover. The cooling and heat insulation plate is attached to the outer side of the feeding pipe. A mounting base is fixedly connected to the left side of the upper end of the feeding pipe. A displacement seat is slidably installed on the upper end of the mounting base. A hopper is fixedly installed on the upper end of the displacement seat. A telescopic cylinder is provided on the left end of the displacement seat. A servo motor is provided on the left end of the feeding pipe. A feeding auger is provided inside the feeding pipe. A discharge port is opened on the right end of the feeding pipe. The heat insulation cover is installed on the right end of the feeding pipe.

[0006] Preferably, the end of the feeding pipe is protected by a cooling heat insulation plate, which effectively isolates the influence of the high temperature of the kiln on the material in the feeding pipe. After feeding is completed, the heat insulation cover is closed on the end of the feeding pipe to achieve sealing protection of the discharge port, prevent heat from entering the feeding pipe through the discharge port, improve the protection effect, avoid damage to the structural components of the feeding device by high temperature, and ensure the accuracy of the feeding amount.

[0007] Preferably, the cooling insulation plate is equipped with a heat exchange coil inside, and the upper and lower sides of the left end face of the cooling insulation plate are provided with connecting joints, which are connected to both ends of the heat exchange coil.

[0008] Preferably, a fixing plate is fixedly connected to the left side of the upper end of the mounting base, the fixed end of the telescopic cylinder is fixedly connected to the fixing plate, and the output end of the telescopic cylinder is fixedly connected to the displacement seat.

[0009] Preferably, a feeding hole is provided on the right side of the upper end of the mounting base, and the feeding hole is connected to the feeding pipe. The displacement seat is provided with the same feeding hole, and the feeding hole is connected to the bottom opening of the hopper.

[0010] Preferably, the two ends of the feeding auger are rotatably connected to the left and right ends of the feeding pipe, respectively, and the left end of the feeding auger is fixedly connected to the output end of the servo motor.

[0011] Preferably, a rotating seat is provided at the right end of the feeding pipe on the side of the discharge port. The rotating seat is connected to the right end of the feeding auger, and a scraper is provided on the surface of the rotating seat.

[0012] Preferably, a groove is provided on the right end face of the heat insulation cover, which is adapted to the scraper. A connecting rod is fixedly connected to the side of the left end face of the heat insulation cover. The connecting rods are distributed in a ring array. The left end of the connecting rod extends to the outside of the cooling heat insulation plate and is fixedly connected to a ring seat. The ring seat and the cooling heat insulation plate are sleeved together. The upper end of the ring seat and the displacement seat are fixedly connected through a transmission rod. The connecting rod and the right end of the feeding pipe are slidably connected.

[0013] The beneficial effects of this utility model are:

[0014] 1. The feeding device for the carbon kiln and jade glaze kiln uses a material feeding device to pour the firing material into the storage bin and then into the feeding pipe through the bottom feeding hole. The servo motor drives the feeding auger to rotate, pushing the material to move in the feeding pipe and out of the discharge port, thus realizing the feeding operation. At the same time, when the feeding auger rotates, it drives the rotating seat to rotate synchronously, and the scraper cleans the discharge port to prevent the material from sticking and clogging the discharge port, ensuring the accuracy of the feeding amount and facilitating the control of the feeding amount, thereby improving practicality.

[0015] 2. The feeding device for the carbon kiln and jade glaze kiln uses a telescopic cylinder for control of the hopper. During feeding, the telescopic cylinder pushes the displacement seat to move, and the material enters the feeding pipe through the feeding hole. The connection of the transmission rod causes the annular seat to move synchronously outside the cooling insulation plate, pushing the heat insulation cover to move, exposing the end of the feeding pipe for easy discharge from the outlet. After feeding is completed, the telescopic cylinder drives the displacement seat to reset, and the feeding hole is misaligned, so that the mounting seat forms a seal and separation from the bottom of the hopper. Simultaneously, the heat insulation cover covers the outside of the outlet, sealing the outlet and reducing the impact of heat on the feeding pipe. The separation of the hopper and the feeding pipe also prevents heat from being transferred into the hopper, affecting material storage and improving practicality. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a feeding device for a carbon kiln jade glaze kiln, including a feeding pipe 1, a cooling and heat insulation plate 2, a hopper 5, a servo motor 7, and a heat insulation cover 8. The cooling and heat insulation plate 2 is fitted onto the outer side of the feeding pipe 1. A heat exchange coil is installed inside the cooling and heat insulation plate 2. The cooling and heat insulation plate 2 is made of refractory material. Connecting joints 21 are provided on both the upper and lower sides of the left end face of the cooling and heat insulation plate 2. The connecting joints 21 are connected to both ends of the heat exchange coil. A mounting base 3 is fixedly connected to the upper left side of the feeding pipe 1. A displacement seat 4 is slidably installed on the upper end of the mounting base 3. A hopper 5 is fixedly installed on the upper end of the displacement seat 4. A telescopic cylinder 6 is installed at the left end of the feeding pipe 4, a servo motor 7 is installed at the left end of the feeding pipe 1, a feeding auger 71 is installed inside the feeding pipe 1, and a discharge port 9 is opened on the right end face of the feeding pipe 1. A heat insulation cover 8 is installed on the right end of the feeding pipe 1. The end of the feeding pipe 1 is protected by the cooling heat insulation plate 2, which effectively isolates the influence of the high temperature of the kiln on the material in the feeding pipe 1. After feeding is completed, the heat insulation cover 8 is closed on the end of the feeding pipe 1 to achieve sealing protection of the discharge port 9, prevent heat from entering the feeding pipe 1 through the discharge port 9, improve the protection effect, avoid damage to the structural components of the feeding device by high temperature, and ensure the accuracy of the feeding amount.

[0024] Please see Figure 1 and Figure 2 In this embodiment, a fixing plate 61 is fixedly connected to the left side of the upper end of the mounting base 3. The fixed end of the telescopic cylinder 6 is fixedly connected to the fixing plate 61, and the output end of the telescopic cylinder 6 is fixedly connected to the displacement seat 4. A feeding hole 31 is opened on the right side of the upper end of the mounting base 3. The feeding hole 31 is connected to the feeding pipe 1, and the displacement seat 4 is also provided with the same feeding hole 31. The feeding hole 31 is connected to the bottom opening of the hopper 5. The telescopic cylinder 6 drives the displacement seat 4 to slide on the mounting base 3, which facilitates the adjustment of the position of the hopper 5. When feeding, the two feeding holes 31 overlap, and the material enters the feeding pipe 1 through the feeding hole 31 to realize the feeding operation. After feeding is completed, the hopper 5 moves its side to realize the separation of the hopper 5 and the feeding pipe 1, which avoids the heat from the feeding pipe 1 to the hopper 5 and improves practicality.

[0025] Please see Figure 2 and Figure 4In this embodiment, the two ends of the feeding auger 71 are rotatably connected to the left and right ends of the feeding pipe 1, respectively, and the left end of the feeding auger 71 is fixedly connected to the output end of the servo motor 7. The right end of the feeding pipe 1 is provided with a rotating seat 72 on the side of the discharge port 9. The rotating seat 72 is connected to the right end of the feeding auger 71, and a scraper 73 is provided on the surface of the rotating seat 72. After the burning material enters the left end of the feeding pipe 1, the feeding auger 71 is rotated by the servo motor 7, which can push the material to move in the feeding pipe 1, push the material to the right, and discharge it from the discharge port 9. At the same time, the synchronous rotation of the rotating seat 72 makes the scraper 73 clean the discharge port 9, prevent the material from adsorbing and sticking to the discharge port 9, avoid blockage, and ensure the accuracy of the discharge amount.

[0026] Please see Figure 1 , Figure 2 and Figure 5 In this embodiment, a groove is provided on the right end face of the heat insulation cover 8, which is adapted to the scraper 73. A connecting rod 81 is fixedly connected to the side of the left end face of the heat insulation cover 8. The connecting rods 81 are arranged in a ring array. The left end of the connecting rod 81 extends to the outside of the cooling heat insulation plate 2 and is fixedly connected to an annular seat 82. The annular seat 82 and the cooling heat insulation plate 2 are sleeved together. The upper end of the annular seat 82 and the displacement seat 4 are fixedly connected through a transmission rod 83. The connecting rod 81 and the right end of the feeding pipe 1 are slidably connected. When feeding, the heat insulation cover 8 moves outward, so that the discharge port 9 is exposed and the material flows out from the discharge port 9 to realize feeding. After feeding is completed, the displacement seat 4 moves, and the transmission rod 83 drives the annular seat 82 to move to the left. The heat insulation cover 8 covers the end of the feeding pipe 1 to seal and isolate the discharge port 9, so as to prevent heat from affecting the internal structural components through the discharge port 9. The heat insulation cover 8 is made of refractory material.

[0027] During operation, the calcined material is poured into the hopper 5 for storage. When feeding, the telescopic cylinder 6 pushes the displacement seat 4 to move, causing the two feeding holes 31 to align. Simultaneously, the transmission rod 83 connects, synchronously pushing the annular seat 82 to move, causing the heat insulation cover 8 to move outwards, exposing the discharge port 9. The material enters the feeding pipe 1 through the feeding holes 31, and then the servo motor 7 drives the feeding auger 71 to rotate, pushing the material through the feeding pipe 1. The material is pushed to the right and discharged from the discharge port 9. Simultaneously, the rotating seat 72 rotates synchronously. The scraper 73 cleans the discharge port 9, preventing material from adhering to and sticking to the discharge port 9, avoiding blockage, and ensuring the accuracy of the discharge volume. After the feeding is completed, the telescopic cylinder 6 drives the displacement seat 4 to reset, the two feeding holes 31 are misaligned, the mounting seat 3 forms a closure on the bottom of the hopper 5, and the heat insulation cover 8 covers the end of the feeding pipe 1, sealing and isolating the discharge port 9 to prevent heat from affecting the internal structural components through the discharge port 9. The separation of the hopper 5 and the feeding pipe 1 also prevents heat from being transferred to the hopper 5, affecting material storage, and improving practicality.

[0028] Through the above steps, the end of the feeding pipe 1 is protected by the cooling heat insulation plate 2, which effectively isolates the influence of the high temperature of the kiln on the material in the feeding pipe 1. After feeding is completed, the heat insulation cover 8 is closed on the end of the feeding pipe 1 to achieve sealing protection of the discharge port 9, preventing heat from entering the feeding pipe 1 through the discharge port 9, thus improving the protection effect, avoiding damage to the structural components of the feeding device by high temperature, and ensuring the accuracy of the feeding amount. This solves the problem that the existing feeding device for baking in carbon kilns and jade glaze kilns has poor protection effect, and the discharge port is open, so the heat in the kiln directly affects the feeding structure through the opening, resulting in damage and deformation, and affecting the feeding amount.
