Description

Technical Field

[0001] This utility model belongs to the field of mica processing and production technology, and relates to kiln equipment, especially to a material dispersing mechanism for a mica roasting kiln. Background Technology

[0002] In mica processing, calcination is a crucial step to remove the water of crystallization. Currently, mica calcination is primarily carried out in kilns, with the mica material transported to the pre-drying and calcination zones via metal conveyor belts. In existing technologies, mica materials are prone to agglomeration during the pre-drying stage, which can affect the uniformity of subsequent calcination and consequently impact the quality of the final product.

[0003] When existing dispersing devices are applied to mica calcining kilns, the gap between the dispersing device and the conveyor belt is difficult to control precisely, easily causing material blockage or insufficient dispersing. These problems lead to uneven heating of the mica during subsequent calcination, ultimately affecting product quality and production efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a material dispersing mechanism for a mica calcining kiln with adjustable spacing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A material dispersing mechanism for a mica calcining kiln includes a dispersing roller disposed above a metal conveyor belt and located between a pre-drying zone and a calcining zone. The dispersing roller is provided with a stirring structure distributed along its length. The two ends of the dispersing roller are respectively located on both sides of the metal conveyor belt, and a height adjustment mechanism is provided at the end of the dispersing roller to adjust the height of the mica passage gap between the dispersing roller and the metal conveyor belt. One end of the dispersing roller is connected to a rotary driver.

[0006] A dispersing roller is installed between the pre-drying zone and the calcination zone. Driven by a rotary driver, the dispersing roller rotates and squeezes the agglomerated material from the pre-drying zone onto the metal conveyor belt, thus dispersing the material. A height adjustment mechanism ensures a suitable distance between the dispersing roller and the metal conveyor belt, guaranteeing effective dispersing and efficiency.

[0007] In the aforementioned material dispersing mechanism of the mica calcining kiln, the dispersing structure includes a spiral-shaped dispersing impeller, which is integrated with the dispersing roller. The spiral-shaped dispersing impeller design enables continuous agitation during rotation, more effectively dispersing the mica material and improving dispersing efficiency.

[0008] In the aforementioned mica calcining kiln's material dispersing mechanism, the height adjustment mechanism includes a lifting seat located at the end of the dispersing roller. The lifting seat is connected to a height adjustment bracket via a guide unit. A height adjustment unit is located between the lifting seat and the height adjustment bracket. A rotary driver is fixed to one of the lifting seats, and the drive end of the rotary driver is connected to the end of the dispersing roller. The height adjustment unit allows for flexible adjustment of the mica passage gap height between the dispersing roller and the metal conveyor belt, ensuring optimal dispersing effect. The connection between the lifting seat and the height adjustment bracket via the guide unit ensures the stability of the lifting seat during vertical movement, reducing the risk of uneven dispersing due to shaking or offset.

[0009] In the aforementioned material dispersing mechanism of the mica calcining kiln, the guiding unit includes a slider mounted on the lifting seat, and the height adjusting bracket is equipped with a slide rail that cooperates with the slider. The sliding of the slider on the slide rail makes the movement of the lifting seat smoother, reducing noise and wear caused by friction or vibration, and improving the operational stability and service life of the equipment.

[0010] In the aforementioned material dispersing mechanism of the mica calcining kiln, there are two sliders, each fixed to one side of the lifting seat. The inner side of the height adjustment bracket is equipped with slide rails that cooperate with the sliders. The symmetrically distributed sliders on both sides ensure more balanced force distribution on the lifting seat during its vertical movement, effectively preventing tilting or offset caused by unilateral force and ensuring precise control of the gap between the dispersing roller and the metal conveyor belt.

[0011] In the aforementioned material dispersing mechanism of the mica calcining kiln, the height adjustment unit includes a lifting screw, which is threaded onto and screwed onto the height adjustment bracket. The lower end of the lifting screw is connected to the axial limit of the circumferential rotation of the lifting seat, and the upper end of the lifting screw is equipped with a rotating handle. The rotating handle at the upper end of the lifting screw allows the operator to easily rotate the lifting screw, thereby easily and accurately adjusting the height of the lifting seat.

[0012] In the aforementioned material dispersing mechanism of the mica calcining kiln, the upper end of the lifting seat is provided with an inverted U-shaped bracket, and the lower end of the lifting screw passes through the inverted U-shaped bracket and is circumferentially movably connected to it. Fixing nuts located at both ends of the inverted U-shaped bracket are screwed onto the lifting screw, and movable washers are provided between the fixing nuts and the inverted U-shaped bracket. By screwing the fixing nuts located at both ends of the inverted U-shaped bracket onto the lifting screw, the position of the lifting screw can be easily fixed, preventing it from loosening after adjustment, thereby maintaining stable spacing.

[0013] In the aforementioned material dispersing mechanism of the mica calcining kiln, a positioning nut is screwed onto the lifting screw, located on the inner and / or outer side of the crossbar on the height adjustment bracket. The positioning nut facilitates adjustment of the height adjustment mechanism. Furthermore, the positioning nut allows for fine-tuning of the lifting screw's position, ensuring accurate height adjustment.

[0014] In the material dispersing mechanism of the aforementioned mica calcining kiln, a bearing is provided between the dispersing roller and the lifting seat. The bearing significantly reduces the direct contact friction between the dispersing roller and the lifting seat, reduces energy loss due to frictional resistance, improves rotational efficiency, and helps to enhance the dispersing effect of the mica material.

[0015] In the aforementioned material dispersing mechanism of the mica calcining kiln, the rotary drive includes a drive motor, which is connected to the end of the dispersing roller via a commutator. The drive motor is also fixed to the lifting base via the commutator. The drive motor is rigidly connected to the lifting base via the commutator, thus avoiding misalignment of the transmission shaft caused by height changes when the lifting base is adjusted. This synchronous motion characteristic ensures consistent transmission efficiency throughout the entire stroke range, preventing attenuation of dispersing efficiency due to transmission shaft misalignment.

[0016] Compared with existing technologies, the material dispersing mechanism of this mica calcining kiln has the following advantages: 1. It features an adjustable spacing design, allowing for precise spacing adjustment, resulting in better dispersing effect and higher efficiency. 2. It has strong applicability; the integrated structural design makes it suitable for dispersing operations using different mechanisms. 3. It has high stability; the lifting seat and drive motor are integrated, and both ends of the roller have support structures, ensuring stable dispersing effect. Attached Figure Description

[0022] like Figures 1 to 4 As shown, the material dispersing mechanism of the mica calcining kiln includes a dispersing roller 1 disposed above the metal conveyor belt 2 and located between the pre-drying zone 4 and the calcining zone 5. The dispersing roller 1 is provided with a stirring structure 11 distributed along its length. The two ends of the dispersing roller 1 are respectively located on both sides of the metal conveyor belt 2, and the ends of the dispersing roller 1 are provided with a height adjustment mechanism 3 that can adjust the height of the mica passage gap 21 between the dispersing roller 1 and the metal conveyor belt 2. One end of the dispersing roller 1 is connected to a rotary driver 12.

[0023] By installing a dispersing roller 1 with a dispersing structure 11 above the metal conveyor belt 2, uniform dispersion of materials is achieved after pre-drying and before calcination. The dispersing structure 11 is distributed along the length of the roller body, physically breaking up agglomerated materials and achieving the effect of dispersing materials and preventing material accumulation. By setting an adjustable height adjustment mechanism 3 with an adjustable mica passage gap 21 at both ends of the dispersing roller 1, adaptive control of the dispersing roller 1 is achieved, thereby increasing the uniformity and stability of dispersing.

[0024] More specifically, the agitation structure 11 includes a spiral agitation impeller 111, and the agitation impeller 111 is integrated with the agitation roller 1.

[0025] like Figure 4 As shown, the height adjustment mechanism 3 includes a lifting seat 31 disposed at the end of the dispersing roller 1. The lifting seat 31 is connected to the height adjustment bracket 33 through the guide unit 32. A height adjustment unit 34 is provided between the lifting seat 31 and the height adjustment bracket 33. A rotary driver 12 is fixed on one of the lifting seats 31. The driving end of the rotary driver 12 is connected to the end of the dispersing roller 1.

[0026] In this embodiment, lifting seats 31 are installed at both ends of the dispersing roller 1 to support the dispersing roller 1 and adjust its height. Height adjustment brackets 33 are fixed on both sides of the furnace body structure to provide stable support for the entire dispersing mechanism.

[0027] More specifically, the guide unit 32 includes a slider 311 mounted on the lifting seat 31, and a slide rail 331 mounted on the height adjustment bracket 33 that can cooperate with the slider 311.

[0028] More specifically, there are two sliders 311, which are fixed on both sides of the lifting seat 31 respectively, and the inner side of the height adjustment bracket 33 is provided with slide rails 331 that cooperate with the sliders 311.

[0029] More specifically, the height adjustment unit 34 includes a lifting screw 341, which is threaded onto and screwed onto the height adjustment bracket 33. The lower end of the lifting screw 341 is connected to the lifting seat 31 for circumferential rotation and axial limiting. The upper end of the lifting screw 341 is provided with a rotating handle 342.

[0030] In this embodiment, the height is adjusted by rotating the handle 342 to drive the lifting screw 341. The outer diameter of the rotating handle 342 is much larger than the outer diameter of the lifting screw 341, and a handle for easy adjustment is provided on the outside of the rotating handle 342.

[0031] More specifically, the upper end of the lifting seat 31 is provided with an inverted U-shaped bracket 312, the lower end of the lifting screw 341 passes through the inverted U-shaped bracket 312 and is circumferentially connected to it, and the lifting screw 341 is screwed with fixing nuts 343 located at both ends of the inverted U-shaped bracket 312, and a movable washer 344 is provided between the fixing nut 343 and the inverted U-shaped bracket 312.

[0032] More specifically, the lifting screw 341 is screwed with positioning nuts 345 located on the inner and outer sides of the crossbar 332 on the height adjustment bracket 33.

[0033] More specifically, a bearing 35 is provided between the dispersing roller 1 and the lifting seat 31.

[0034] like Figure 3 As shown, the rotary driver 12 includes a drive motor 121, which is connected to the end of the dispersing roller 1 via a commutator 122. The drive motor 121 is fixed on the lifting seat 31 via the commutator 122.

[0035] In this embodiment, the commutator 122 can control the forward and reverse rotation of the dispersing roller 1, thereby controlling the material to be evenly distributed on the metal conveyor belt 2 and preventing the material from falling off.

[0036] The working principle of this embodiment is as follows: During use, the height of the mica passage gap 21 between the dispersing roller 1 and the metal conveyor belt 2 is first adjusted by the height adjustment mechanism 3 according to the thickness and agglomeration degree of the material. The adjustment method involves rotating the rotating handle 342 at the upper end of the lifting screw 341, causing the lifting seat 31 to move the dispersing roller 1 up and down until a suitable mica passage gap 21 height is achieved. Then, the position of the lifting screw 341 is locked by the positioning nut 345 and the fixing nut 343 to prevent changes in height during use.

[0037] The agglomerated material from the pre-drying zone 4 arrives below the dispersing roller 1. The drive motor 121 is started, and the dispersing roller 1 is rotated through the commutator 122. The spiral agitator impeller 111 on the dispersing roller 1 disperses and agitates the material, breaking up the agglomerates and distributing the material evenly on the metal conveyor belt 2. The metal conveyor belt 2 then transports the evenly dispersed material to the roasting zone 5 for the next process.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
