Description

Technical Field

[0001] This application relates to the field of calcination apparatus technology, and in particular to a potassium feldspar calcination apparatus for cast iron coatings. Background Technology

[0002] Potassium feldspar, an important industrial mineral, is widely used in ceramics, glass, fertilizers, and foundry coatings. In the foundry industry, calcined potassium feldspar can be used as a raw material for cast iron coatings; its calcination effect directly affects the coating's refractoriness, adhesion, and the quality of the finished castings. Traditional potassium feldspar calcination processes often employ stationary calcination furnaces, which present the following problems:

[0003] Low material loading and unloading efficiency: The material inlet and outlet of traditional calcining furnaces are designed to be fixed, requiring frequent manual operation, which leads to low loading and unloading efficiency and is prone to material loss or pollution.

[0004] Continuous production is difficult: most existing equipment operates intermittently, which cannot achieve continuous feeding and discharging, thus limiting the improvement of production efficiency. Summary of the Invention

[0005] The purpose of this application is to provide a potassium feldspar calcination device for cast iron coatings to solve the above-mentioned problems. Through an innovative material transfer system and automated control, the efficiency of potassium feldspar calcination is significantly improved, solving the problems of cumbersome material loading and unloading and difficulties in continuous production in traditional processes, and providing a highly efficient calcination solution for the cast iron coatings industry.

[0006] This application achieves the above objectives through the following technical solutions:

[0007] A potassium feldspar calcination device for cast iron coatings includes: a calcination furnace with material inlets at both the front and rear, and a base at the bottom; a material cage movably connected inside the calcination furnace, connected to a drive assembly capable of translating it, the cage having a box-like structure with open top and bottom, and gaps on both sides to avoid the burner head, and densely arranged ventilation openings on both sides; two sealing plates fixedly installed at the front and rear of the material cage to open and close the material inlets; a first hydraulic cylinder extending vertically along its length, with its output end facing upwards; and a base plate fixedly connected to the output end of the first hydraulic cylinder, configured to fit the area of ​​the bottom opening of the material cage to allow entry into the material cage to close its bottom opening.

[0008] In some embodiments, a conveyor is also included, which is configured to convey the end of the material above the material inlet when it is located outside the calcining furnace.

[0009] In some embodiments, the drive assembly includes: a support capable of providing support; a second hydraulic cylinder bracket fixedly mounted on the support; a second hydraulic cylinder fixedly mounted on the second hydraulic cylinder bracket and extending axially along the translational direction of the material inlet; a connecting seat fixedly connected to the output end of the second hydraulic cylinder; and a third hydraulic cylinder fixedly mounted on the connecting seat and whose output end is fixedly connected to the sealing plate.

[0010] In some embodiments, the drive assembly further includes a slide block and a slide bar, the slide block being fixedly connected to the support, the slide bar being fixedly connected to the slide block and extending along the axial direction of the third hydraulic cylinder, and the connecting seat having a groove adapted to the slide bar so that the connecting seat slides into contact with the slide bar through the groove.

[0011] In some embodiments, the vent is shaped like a hole or a strip and extends through the sidewall of the material cage.

[0012] In some embodiments, the base is provided with a slide rail for the sealing plate to slide.

[0013] Compared to existing technologies, this application adopts a translational material cage design. The material cage is translated by a drive component, allowing for continuous loading and unloading operations from the front to the rear of the calcining furnace, significantly improving loading and unloading efficiency. The bottom lifting plate is driven by a first hydraulic cylinder to lift the bottom plate, which can reduce the drop during material loading to reduce dust flying, and can also seal the bottom of the material cage during calcination to prevent heat loss and material overflow. It has a continuous operation mode. Through the reciprocating translation of the material cage, the calcining furnace can achieve continuous production, reduce downtime, and increase production capacity. Attached Figure Description

Detailed Implementation

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] like Figure 1-2 As shown, a potassium feldspar calcination device for cast iron coatings includes: a calcination furnace 1 with material inlets 2 at both the front and rear, and a base 8 at the bottom of the calcination furnace 1; a material cage 3 movably connected inside the calcination furnace 1, connected to a drive assembly capable of driving its translation, having a box-like structure with open top and bottom, and gaps on both sides between the cage and the calcination furnace 1 to avoid the burner head, and densely constructed ventilation openings 4 on both sides of the material cage 3; two sealing plates 5 fixedly installed at the front and rear of the material cage 3 to open and close the material inlets 2; a first hydraulic cylinder 10 extending vertically along its length, with its output end facing upwards; and a base plate 11 fixedly connected to the output end of the first hydraulic cylinder 10, configured to fit the area of ​​the bottom opening of the material cage 3, so as to allow entry into the material cage 3 to close its bottom opening.

[0022] The calcining furnace 1 in this embodiment is prior art. The only difference between it and the present application is the material inlet and outlet. The burner head on the calcining furnace 1 is located on both sides of the calcining furnace 1. The heat can pass through the ventilation port 4 to heat the potassium feldspar in the material cage 3. The material cage 3 is driven to move horizontally by the drive component, which can drive the material in and out of the calcining furnace 1. When the bottom plate 11 is at the bottom opening of the material cage 3, it can provide support when the material cage 3 is pushed.

[0023] In some embodiments, a conveyor 6 is also included, which is configured to convey the end of the material inlet 2 above the calcining furnace 1.

[0024] The conveyor 6 in this embodiment is prior art and is not shown in the accompanying drawings. In some embodiments, it is a material hoist or a belt conveyor or a combination of both.

[0025] In some embodiments, the drive assembly includes: a support 9 capable of providing support; a second hydraulic cylinder bracket 12 fixedly mounted on the support 9; a second hydraulic cylinder 13 fixedly mounted on the second hydraulic cylinder bracket 12 and extending axially along the translational direction of the material inlet 2; a connecting seat 14 fixedly connected to the output end of the second hydraulic cylinder 13; and a third hydraulic cylinder 15 fixedly mounted on the connecting seat 14 and whose output end is fixedly connected to the sealing plate 5.

[0026] In this embodiment, the second hydraulic cylinder 13 and the third hydraulic cylinder 15 work together to increase the stroke of the material cage 3. By extending and retracting in the same direction, they can drive the material cage 3 to enter and exit from the material inlets 2 at the front and rear of the calcining furnace 1 to complete the feeding and unloading.

[0027] In some embodiments, the drive assembly further includes a slide block 16 and a slide bar 17. The slide block 16 is fixedly connected to the support 9, and the slide bar 17 is fixedly connected to the slide block 16 and extends along the axial direction of the third hydraulic cylinder 15. The connecting seat 14 is provided with a slide groove 18 adapted to the slide bar 17 so that the connecting seat 14 slides with the slide bar 17 through the slide groove 18.

[0028] In this embodiment, the connecting seat 14 is used to connect the second hydraulic cylinder 13 and the third hydraulic cylinder 15. In order to improve the load-bearing capacity, the slide bar 17 is supported by the slide seat 16 so that the connecting seat 14 can slide and guide on the slide bar 17, thereby increasing the stability of the connecting seat 14.

[0029] In some embodiments, the vent 4 is shaped like a hole or a strip and penetrates the side wall of the material cage 3, allowing space for heat to circulate.

[0030] In some embodiments, the base 8 is provided with a slide rail 7 for the sealing plate 5 to slide. The bottom sides of the sealing plate 5 are slidably engaged with the slide rail 7. When the material cage 3 and the sealing plate 5 move synchronously, the sealing plate 5 can slide on the slide rail 7, increasing the stability and load-bearing capacity of the material cage 3 and the sealing plate 5. The sealing plate 5 has a multi-layer structure, with an inner insulation layer and an outer reinforcing layer. In some embodiments, the reinforcing layer is made of steel.

[0031] In the above structure, the second hydraulic cylinder 13 and the third hydraulic cylinder 15 retract, pulling the material cage 3 and the sealing plate 5 out of the calcining furnace 1. Simultaneously, the first hydraulic cylinder 10 activates, causing the bottom plate 11 to approach the bottom surface of the material cage 3 and the sealing plate 5, allowing the bottom plate 11 to seal the bottom opening of the material cage 3. Then, the conveyor 6 starts, conveying the potassium feldspar to be calcined into the material cage 3. At this time, the bottom plate 11 can be raised to reduce the material drop height, continuously descending as the material drops to fill the material cage 3. The conveyor 6 then stops feeding material. A hydraulic cylinder 10 is activated and retracts, causing the bottom plate 11 to be lower than the bottom surface of the material cage 3, thus avoiding affecting the movement of the material cage 3. The second hydraulic cylinder 13 and the third hydraulic cylinder 15 are activated and extend, causing the material cage 3 to enter the calcining furnace 1. The calcining furnace 1 is activated and calcined for potassium feldspar. After calcination is completed, the second hydraulic cylinder 13 and the third hydraulic cylinder 15 are activated and continue to extend, causing the material cage 3 to move out from the material outlet 2 on the other side. The calcined potassium feldspar in the material cage 3 falls out, completing the unloading. Repeating the above steps can continuously calcine potassium feldspar, thereby improving the calcination efficiency.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
