Description

Technical Field

[0001] This utility model relates to the field of ceramic processing equipment technology, specifically to a ceramic sintering kiln. Background Technology

[0002] A kiln is a device used for heating, baking, or firing materials, commonly found in industries such as ceramics, glass, and metal processing. It is generally constructed of bricks and stones and can be manufactured in various sizes and specifications to meet specific needs. It typically operates using combustible gas, oil, or electricity. Based on its heating method, it can be mainly divided into two types: fire kilns and electric kilns. Electric kilns, which use heating wires, silicon carbide rods, or silicon molybdenum rods for electric heating, offer easier temperature control compared to fire kilns, allowing for precise operation and featuring energy efficiency and environmental friendliness. Therefore, they are increasingly favored by ceramic manufacturers and widely used in the production of various specialty ceramic products. However, the heating device in traditional electric kilns is generally fixed to the kiln wall and cannot be freely adjusted according to the size of the ceramic blanks. The entire kiln must be heated to the target temperature before firing can be completed, which is not energy-efficient or environmentally friendly. Furthermore, the fired blanks need to cool for a period of time before they can be manually removed from the kiln, which is very time-consuming and labor-intensive. A new type of kiln is needed to solve these problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a ceramic sintering kiln, comprising a base, a sintering chamber at the end of the base, a furnace door mechanism at the entrance of the sintering chamber, a lifting frame vertically slidably connected to the top surface of the sintering chamber, two parallel suspension rails connected to the bottom of the lifting frame inside the sintering chamber, a heating component slidably connected between the two suspension rails, a vertical rack on the side of the lifting frame meshing with a gear at the output end of the lifting motor, a conveying groove on the top surface of the base, a drive shaft in a drive mechanism rotatably connected to both ends of the conveying groove, the drive shaft threadedly connected to the bottom of the conveying platform, and the conveying platform slidably connected to the conveying groove.

[0004] Furthermore, the furnace door mechanism includes a double sliding door, with the bottom protrusion of the double sliding door slidably connected to the track platforms on both sides of the base, the inner sliding strip of the double sliding door slidably connected to the upper sliding groove of the sintering chamber entrance, a handle on the outer side of the double sliding door, and mutually cooperating latches and pin holes on the opposite sides of the two door panels of the double sliding door.

[0005] Furthermore, the heating assembly includes a sliding seat, which is slidably connected to a through groove on the suspension rail. Metal guide rails on both sides of the through groove are connected to an external power source via wiring from a hollow lifting frame. The metal guide rails are in contact with brushes on the bottom surface of the top cover of the sliding seat. The brush wires are connected to vertically arranged sockets on the sliding seat, and the corresponding sockets on both sides are connected to the electrodes at both ends of the heating rod.

[0006] Furthermore, the lifting frame has an inverted U-shaped structure. The lifting arms on both sides of the lifting frame extend into the sintering chamber through the lifting holes on the top surface of the sintering chamber. The bottom of the lifting arm is connected to the hollow connecting rod between the two suspension rails. A rack is set on the outside of the lifting arm, and the groove on the inside of the lifting arm fits with the friction block on the inside of the lifting hole.

[0007] Furthermore, the drive mechanism includes a drive motor, which is built into a transverse groove on the top surface of the base. The gears at the ends of each drive shaft pass through the transverse groove and mesh with the gears on the output shaft of the drive motor.

[0008] Furthermore, the conveyor table includes a carrier plate, a drive block on the bottom surface of the carrier plate is threadedly connected to the drive shaft, a load-bearing wheel is provided between two adjacent drive blocks, and a heat-resistant plate is provided on the top surface of the carrier plate.

[0009] The beneficial effects of this invention are as follows: This invention uses a drive motor to rotate each drive shaft, thereby transporting a conveyor platform carrying ceramic blanks into the sintering chamber. The lifting frame in the sintering chamber can be height-adjusted via a lifting motor. The heating components on the lifting frame can be adjusted in number and spacing by replacing or sliding the sliding seats. This device meets the need for close-range firing of ceramics of different sizes. After sintering, the blanks can be quickly moved out of the sintering chamber via the conveyor platform, featuring energy saving, emission reduction, time and labor saving, and strong applicability.

The two door panels of the double sliding door 7 are provided with mutually cooperating pins and pin holes on their opposite sides. The top surface of the sintering chamber 2 is vertically slidably connected to the lifting frame 3, which has an inverted U-shaped structure. The lifting arms 302 on both sides of the lifting frame 3 extend into the sintering chamber 2 through the lifting holes 202 on the top surface of the sintering chamber 2. The bottom of the lifting arms 302 is connected to the hollow connecting rod 403 between the two parallel suspension rails 4. A vertical rack 301 is provided on the outside of the lifting arms 302.

The groove 303 on the inner side of the lifting arms 302 fits against the friction block on the inner side of the lifting hole 202, so that the friction force and gravity on the lifting frame 3 are balanced.

[0018] In this embodiment, a heating assembly is provided between the two suspension rails 4. The heating assembly includes a sliding seat 8, which is slidably connected to the through groove 401 on the suspension rail 4. The metal guide rails 402 on both sides of the through groove 401 are connected to an external power source through wiring of the hollow lifting frame 3. The metal guide rails 402 are in contact with the brushes on the bottom surface of the top cover of the sliding seat 8. The brush wires are connected to the vertically arranged insertion holes 801 on the sliding seat 8. The corresponding insertion holes 801 on both sides are respectively connected to the electrodes at both ends of the heating rod 9. The sliding seat 8 has different specifications, and each specification corresponds to the installation of a different number of heating rods 9.

[0019] In this embodiment, a conveying groove 101 is formed on the top surface of the base 1.

Arrange the ceramic blanks to be fired on the top surface of the heat-resistant plate 13, start the drive motor 10 to drive each drive shaft 6 to rotate, and move the conveyor table into the sintering chamber 2. Start the lifting motor 5 to lower the heating components to a suitable height, at which point each row of blanks is sandwiched between the two heating rods 9. Close the double sliding door 7 by using the handle 703, so that the pin is inserted into the insertion hole. Start each heating rod 9 to fire the ceramic blanks. After sintering is completed, reopen the double sliding door 7, start the drive motor 10 in reverse, and move the conveyor table out of the sintering chamber 2.

[0022] This invention uses a drive motor 10 to rotate each drive shaft 6, thereby conveying a conveyor platform carrying ceramic blanks into the sintering chamber 2. The lifting frame 3 in the sintering chamber 2 can be adjusted in height via a lifting motor 5. The heating components on the lifting frame 3 can be adjusted in number and spacing by replacing or sliding the sliding seat 8. The device meets the requirements for close-range firing of ceramics of different sizes. After sintering, the blanks can be quickly moved out of the sintering chamber 2 via the conveyor platform.
