Description

Technical Field

[0001] This utility model belongs to the field of infrared drying ovens and relates to a silicon dioxide non-metallic track for an infrared drying oven. Background Technology

[0002] Currently, there are various types of dryers on the market, including disc dryers, drum dryers, microwave oven dryers, and infrared heating dryers. Each model has a different heating method, but they all face problems such as low working efficiency, high operating costs, low drying temperature, high equipment investment, and high increase in magnetic foreign matter.

[0003] Disc dryers use steam or oil as heating media, with internal heating coils that maintain low temperatures, typically below 200℃. Output is also low. The lithium material powder to be dried rests on a metal rotating disc, propelled by metal scrapers. The sliding friction between the disc and scrapers generates fine metal powder. The resulting lithium material powder leaving the dryer has a very high increase in magnetic impurities.

[0004] Rotary drum dryers use dry stainless steel heating tubes to heat the outer side of the inner drum, resulting in indirect heating and high energy consumption. Lithium powder is placed inside the stainless steel drum. The drum rotates under external force, causing continuous collisions between the lithium powder and the drum, which both damages the material's surface and generates a significant increase in magnetic foreign matter. Microwave oven dryers are only suitable for small-scale production or sample processing and cannot meet the requirements of high-capacity processes.

[0005] However, microwave oven dryers on the market overcome the drawbacks of high magnetic foreign matter accumulation, low capacity, low efficiency, and high maintenance costs. Infrared chain plate dryers are used to dry lithium material particles or powder. The chain plates are fixed at both ends to a non-standard chain with metal rollers mounted on it. During operation, the rollers roll on a track. The drying oven track is currently made of 304 stainless steel angle steel. Since both the rollers on the chain and the track are metal, the rolling of the rollers on the angle steel produces very fine metal powder, resulting in increased magnetic foreign matter accumulation in the lithium material powder leaving the machine. This affects product quality. Some equipment manufacturers add a demagnetizer in the next stage of the dryer process, where the lithium material powder exiting the dryer undergoes another demagnetization. This method has some effect, reducing the increase in magnetic foreign matter, but it still doesn't completely remove the magnetic material. Furthermore, it requires additional equipment investment and increases operating costs.

[0006] This invention relates to a silica non-metallic track designed for infrared drying ovens. This track can also be used in other drying equipment with conveying mechanisms. Utility Model Content

[0007] The purpose of this invention is to provide a silica non-metallic track for an infrared drying oven. The track is made of silica non-metallic material, which reduces the increase of magnetic foreign matter. The modified drying oven can dry both industrial-grade lithium material powder and battery-grade lithium material powder. Stainless steel ramps are installed at both ends of the track to ensure that the chain is not stuck or derailed when going up and down the track, thus ensuring the normal operation of the drying oven.

[0008] The technical solution adopted in this utility model is as follows:

[0009] A silica non-metallic track for an infrared drying oven includes a guide rail mounting base, a guide rail frame, and a silica sheet. The guide rail mounting base is an L-shaped angle steel with a waist-shaped hole in the center of one side. The other side is welded to the side wall of the furnace chamber. The opening of the guide rail mounting base is on top and parallel to the top surface of the furnace chamber. The guide rail frame is a long L-shaped angle steel. One outer side of the guide rail frame is welded to a lead screw, which passes through the waist-shaped hole and is fixedly connected with a bolt. The other side of the guide rail frame is close to the side wall of the furnace chamber. The silica sheet is laid on the track frame to form the track.

[0010] Furthermore, both the guide rail mounting base and the guide rail frame are made of 304 stainless steel.

[0011] Furthermore, the guide rail frame is placed on the guide rail mounting base, and the guide rail frame and the guide rail mounting base are locked together by a lead screw and a stainless steel nut.

[0012] Furthermore, a 304 stainless steel strip is also provided, which is welded to the flat edge of the angle steel with countersunk holes. The distance between the inner edge of the steel strip and the inner side of the other side of the angle steel is used to install the silica plate.

[0013] Furthermore, a stainless steel ramp is also provided, located on both sides of the silica sheet, for the transition connection between the upper surface of the silica sheet and the angle steel surface on the track frame. The stainless steel ramp assists the chain on the track.

[0014] Furthermore, the stainless steel ramp component is provided with countersunk holes, which, together with bolts, connect the stainless steel ramp component to the upper surface of the track frame.

[0015] Furthermore, metal rollers are mounted on the chain, and these rollers roll along the track.

[0016] Furthermore, the chain and chain plate operate in a closed loop, with one set of chain and chain plate equipped with four tracks, located at the lower left, upper left, lower right, and upper right positions respectively.

[0017] Furthermore, the tracks on the left and right sides are set close to the inner walls of the left and right sides of the furnace.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] 1. No additional demagnetizer is required, which improves work efficiency, reduces operating costs, reduces equipment investment, reduces energy consumption, reduces the increase of magnetic foreign matter, and improves product quality.

[0020] 2. The present invention relates to a silica non-metallic material track. The drying oven track is made of silica non-metallic material, which reduces the increase of magnetic foreign matter. The modified drying oven can dry both industrial-grade lithium material powder and battery-grade lithium material powder.

[0021] 3. Stainless steel ramps were installed at both ends of the track to ensure that the chain does not get stuck or derail when going up or down the track, thus ensuring the normal operation of the drying oven. Attached Figure Description

[0035] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0036] Example

[0037] like Figures 1-8As shown in the preferred embodiment of this utility model, a silica non-metallic track for an infrared drying furnace includes a guide rail mounting base, a guide rail frame, and silica plates. The guide rail mounting base is an L-shaped angle steel with a waist-shaped hole in the center of one side. The other side is welded to the side wall of the furnace. The opening of the guide rail mounting base is at the top and parallel to the top surface of the furnace. This allows the guide rail mounting base to support the guide rail frame, and the installation position of the guide rail frame can be adjusted to a certain extent using the long waist-shaped hole on the guide rail mounting base. The guide rail frame is made of long L-shaped angle steel, and one outer side of the guide rail frame is welded to a lead screw. The lead screw passes through the waist-shaped hole of the guide rail mounting base and is fixed with bolts. At this time, the other side of the guide rail frame is close to the side wall of the furnace. Two guide rail frames at the same height inside the furnace are arranged opposite each other to install silica plates to form a track. Metal rollers run on the track, and chains, chain plates, and other structures are installed on the metal rollers.

[0038] The guide rail mounting base and guide rail frame are both made of 304 stainless steel. Using stainless steel can significantly reduce the increase of magnetic substances caused by rust and wear.

[0039] The guide rail frame is placed on the guide rail mounting base, and a stainless steel nut is installed on the lead screw to lock the guide rail frame on the guide rail mounting base. The installation using the lead screw and nut structure can achieve detachable installation, which is convenient for replacement and maintenance. Of course, other installation methods can also be used, such as using a limit block to limit the installation after the snap-fit ​​structure is installed.

[0040] It also features 304 stainless steel strips, which are welded to the flat edge of the angle steel with countersunk holes. The distance between the inner edge of the steel strip and the inner side of the other side of the angle steel is 53mm. The stainless steel strips are used for adjusting the position of the track, fixing the edge, strengthening the structure, and limiting the position of the silica plate.

[0041] One side of the guide rail frame has a countersunk hole, and a stainless steel screw is inserted into the hole. One end of the screw is welded to the countersunk hole surface and then ground smooth. The screw is set perpendicular to the plane of the angle steel. This structure ensures a firm weld on the screw and does not affect the surface flatness. The countersunk hole should be centered in the transverse position of the angle steel. The distance between adjacent holes is 1200mm. Then, the guide rail frame is placed on the guide rail mounting base and locked with a stainless steel nut.

[0042] A stainless steel ramp is also installed on both sides of the silica sheet. This ramp serves as a transition between the upper surface of the silica sheet and the angle steel surface of the track frame. The ramp assists the chain on the track and primarily guides the metal rollers and chain, facilitating operation. It also defines the position of adjacent components. The cut silica sheet is laid on the angle steel of the track frame; it can be a single section or multiple sections joined together. After laying the sheet, 80mm of length remains at each end of the angle steel. Two stainless steel ramps are installed at this position. These ramps are 53mm wide and 80mm long. The high end is 15mm thick and flush with the silica sheet, while the low end is flush with the angle steel surface of the track frame. Countersunk holes are then drilled in the ramps, and they are bolted to the angle steel. The ramps primarily assist the chain on the track. The chain is a non-standard chain equipped with metal rollers that roll on the track during operation. In other words, the rollers roll on the silica sheet. Silica is a non-metallic material, which reduces the increase of magnetic foreign matter.

[0043] The stainless steel ramp component is provided with countersunk holes. The countersunk holes, together with bolts, connect the stainless steel ramp component to the upper surface of the track frame. Of course, the stainless steel ramp component can also be installed using other structures. This embodiment only points out a more suitable installation method.

[0044] Metal rollers are mounted on the chain and roll on the track. The metal rollers come into contact with the non-metallic silica plate, which prevents the generation of iron filings and reduces the increase of magnetic foreign matter.

[0045] The chain and chain plate system operates in a closed loop. Each chain and chain plate is equipped with four tracks, located at the lower left, upper left, lower right, and upper right positions. The tracks on the left and right sides are flush against the inner left and right walls of the furnace. The upper left and upper right positions have silica plates supporting the ends of the metal rollers. The lower layer operates similarly. The chain and chain plate system is formed by mounting the rollers, creating the entire reciprocating track structure. The upper plane of the lower track mounting base must be at least 120mm above the bottom plane of the furnace.
