[0002] An electric kiln is a device that uses electricity to fire ceramics. It is mainly used for firing ceramic products. An electric kiln mainly consists of a box-type kiln body made of refractory material and heat generated by the current passing through resistance wires. Its working principle is to convert electrical energy into heat and rely on the principle of electrical radiation and heat conduction to fire in an oxidizing atmosphere. An internal support is generally set up inside the electric kiln. The internal support is a device used to support and fix the items inside the kiln. It is commonly used in heat treatment furnaces, industrial furnaces and other equipment.
[0003] In the prior art, such as the electric porcelain kiln firing support proposed in patent application number "CN201320344234.9", multiple layers are placed on the crossbeam, and the columns and crossbeams form a lower blank receiving cavity, and an upper blank receiving cavity is formed above the crossbeam. This utility model can increase the number of blanks loaded in the electric porcelain kiln, thereby reducing energy waste and energy usage costs, while improving the firing qualification rate and production efficiency of electric porcelain products.
[0004] However, the aforementioned patent applications can only support the products to be fired. However, when firing products in an electric kiln, it is sometimes necessary to place the products inside the kiln by suspending them with hooks. The aforementioned patent applications cannot meet the requirements for suspending and placing the products, and cannot adjust the size of the placement space according to the products to be fired, so their applicability is not strong. Utility Model Content
[0005] The purpose of this utility model is to provide an internal support for an electric kiln to solve the problems mentioned in the background art.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] An internal support for an electric kiln includes two frames for supporting the interior of the kiln and bearing the products to be fired. The two frames are fixedly connected to the upper and lower inner walls of the kiln. A kiln door is hinged to one side of the front surface of the kiln. Corner brackets and vertical rods are fixedly connected between the two frames and near the four corners. Several load-bearing frames are sleeved between the four vertical rods. Several movable rods are movably installed inside the load-bearing frames. Adjustment mechanisms are provided on the upper surfaces of the load-bearing frames near the two sides. Several reinforcing plates are fixedly installed inside the four corner brackets.
[0008] The adjustment mechanism includes an insert plate and a fixed frame. The insert plate is inserted into the upper surface of the support frame, and the fixed frame is fixedly installed on the upper surface of the support frame. Several sliding grooves are formed through the outer wall of the insert plate.
[0009] Preferably, each of the movable rods has a sliding rod fixedly connected to both ends, and one end of the sliding rod is movably installed inside the slide groove.
[0010] Preferably, a movable plate is slidably connected inside the fixed frame, and the movable plate is fixedly connected to the insert plate, and a screw is inserted into the upper surface of the fixed frame.
[0011] Preferably, a second nut is threaded onto the outside of the screw and located inside the fixed frame, and the bottom end of the screw is fixedly connected to the movable plate.
[0012] Preferably, a number of the bearing frames are fixedly connected to double-ended threaded rods near both sides of the bottom surface, and a slider and a nut are sleeved on the outside of each of the two double-ended threaded rods near both ends.
[0013] Preferably, each of the two sliders has a fixed rod connected to its outer side wall, and each of the four vertical rods has a number of fixing holes on its outer side wall, with the fixing holes fitting into one end of the rod.
[0014] The beneficial effects of this utility model are:
[0015] 1. In this utility model, two frames are installed inside the furnace body in conjunction with four corner brackets to support and reinforce the internal position of the furnace body. The reinforcement plates and corner brackets form a triangular stable structure, which can better support and reinforce the four corners of the furnace body. The nuts and screws can drive the insert plates to move down. With the help of the sliding groove and sliding rod, the distance between each movable rod can be easily adjusted to accommodate products of different sizes to be fired, and to avoid the gaps being too large, which would prevent the products to be hung from being placed. When hanging is required, the distance between each movable rod can be increased so that the hooks used for hanging can be easily hung on the outside of the movable rods for easy hanging. Through the above operations, the furnace support has good support and reinforcement performance, and can easily support and hang products to be fired, effectively improving its applicability.
[0016] 2. In this utility model, by moving the support frame along the outside of the four vertical rods, the distance between each support frame can be adjusted. By using a slider, a double-ended threaded rod, and a plug rod in conjunction with a fixing hole and a nut, the position between the support frame and the vertical rod can be fixed, making it convenient to adjust the distance between each support frame. This allows for the placement and firing or hanging of products of different sizes to be fired, further improving the applicability. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] An internal support for an electric kiln, such as Figures 1-5As shown, the furnace includes two frames 1 for supporting the interior of the furnace body 17 and bearing the products to be fired. The two frames 1 are fixedly connected to the upper and lower inner walls of the furnace body 17 respectively. The furnace door 18 is connected to one side of the front surface of the furnace body 17 by a hinge. Corner brackets 2 and vertical rods 4 are fixedly connected between the two frames 1 and near the four corners. Several bearing frames 5 are sleeved between the four vertical rods 4. Several movable rods 6 are movably installed inside the bearing frames 5. Adjustment mechanisms are provided on the upper surface of the bearing frames 5 near both sides. Several reinforcing plates 3 are fixedly installed inside the four corner brackets 2. The adjustment mechanism includes an insert plate 14 and a fixed frame 11. The insert plate 14 is inserted into the upper surface of the bearing frame 5, and the fixed frame 11 is fixedly installed on the upper surface of the bearing frame 5. Several sliding grooves 19 are opened through the outer wall of the insert plate 14.
[0027] Several movable rods 6 are fixedly connected to slide rods 15 at both ends, and one end of the slide rod 15 is movably installed inside the slide groove 19.
[0028] A movable plate 13 is slidably connected inside the fixed frame 11, and the movable plate 13 is fixedly connected to the insert plate 14. A screw 16 is inserted into the upper surface of the fixed frame 11. A nut 12 is threadedly fitted onto the outside of the screw 16 and inside the fixed frame 11. The bottom end of the screw 16 is fixedly connected to the movable plate 13. When the nut 12 is rotated, it can only rotate within the fixed frame 11 due to the limitation of the fixed frame 11. The screw 16 is connected to the movable plate 13, and the movable plate 13 is slidably connected to the fixed frame 11, which can limit the movement of the screw 16 to vertical movement only. When the nut 12 is rotated, the screw 16 can be moved downwards due to the threaded engagement, which in turn moves the movable plate 13 downwards, thereby moving the insert plate 14 downwards.
[0029] In use, two frames 1 are installed inside the furnace body 17 in conjunction with four corner brackets 2 to support and reinforce the internal position of the furnace body 17. The reinforcement plates 3 and the corner brackets 2 form a triangular stable structure, which can better support and reinforce the four corners of the furnace body 17. The products to be fired can be placed on the movable rods 6 set inside each of the bearing frames 5, or the products to be fired can be hung on the movable rods 6 for hanging firing.
[0030] The distance between each movable rod 6 can be flexibly adjusted to accommodate products of different sizes for placement or hanging. During adjustment, simply rotate nut 12. With the engagement of the threads, screw 16 moves downwards, causing movable plate 13 to move downwards, which in turn moves insert plate 14 downwards. This allows slide rods 15 to slide relative to each other along the inside of slide groove 19, enabling each slide rod 15 to slide along the inside of the support frame 5, with the spacing gradually decreasing. This reduces the distance between each movable rod 6. Similarly, moving insert plate 14 upwards increases the distance between each movable rod 6. This allows for convenient adjustment of the distance between each movable rod 6, accommodating products of different sizes for support and avoiding excessive spacing that would prevent the placement of products for hanging. When hanging is required, the distance between each movable rod 6 can be increased, allowing the hooks used for hanging to be easily hung on the outside of the movable rods 6 for easy hanging. Through these operations, the furnace support provides excellent support and reinforcement while facilitating the support and hanging of products for firing, effectively improving its applicability.
[0031] Several load-bearing frames 5 are fixedly connected to double-ended threaded rods 7 near both sides of the bottom surface. Two double-ended threaded rods 7 are fitted with sliders 9 and nuts 10 near both ends. The nuts 10 are rotated along the outside of the double-ended threaded rods 7 so that the nuts 10 are pressed against one side of the sliders 9, thus squeezing and fixing the position of the sliders 9.
[0032] Both sliders 9 are fixedly connected to the outer walls of the two sliders 9, and the outer walls of the four vertical rods 4 are provided with several fixing holes, and the fixing holes fit with one end of the fixing rod 8. When the sliders 9 are moved along the outside of the double-ended threaded rod 7, one end of the fixing rod 8 is inserted into the corresponding fixing hole, which can fix the position between the bearing frame 5 and the vertical rod 4.
[0033] Specifically, the distance between each support frame 5 can be adjusted according to the size of the product to be fired, thereby adjusting the space size inside the furnace body 17 to accommodate products of different sizes for placement and firing or hanging, further improving the applicability. During adjustment, the support frame 5 is moved along the outside of the four vertical rods 4 to adjust the distance between each support frame 5. After adjustment, the slider 9 is moved along the outside of the double-threaded rod 7, driving one end of the insertion rod 8 to be inserted into the corresponding fixing hole, and the nut 10 is rotated along the outside of the double-threaded rod 7 so that the nut 10 is tightly attached to one side of the slider 9, pressing and fixing the position of the slider 9, thereby fixing the position between the support frame 5 and the vertical rod 4, and conveniently completing the adjustment of the distance between each support frame 5. The furnace support is made of cast iron, which has excellent high temperature resistance.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
