Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of powder metallurgy, relates to powder sintering, and particularly relates to a portable loading rack and a tube furnace. Background Art
[0002] Tube furnaces are mainly used in industries such as metallurgy, glass, heat treatment, lithium-ion battery anode and cathode materials, new energy, and abrasives to measure the formation of materials under certain temperature conditions. The furnace type structure is simple, easy to operate, convenient to control, and can be continuously produced. Tube furnaces include various furnace types such as single-tube, double-tube, horizontal, openable, vertical, single-temperature zone, double-temperature zone, and triple-temperature zone, and have the advantages of safety and reliability, high temperature control accuracy, good heat preservation effect, large temperature range, high uniformity of furnace chamber temperature, multiple temperature zones, and optional atmosphere.
[0003] Tube furnaces are essential equipment in the process of material preparation or modification. The furnace tubes can be selected and configured with materials such as heat-resistant steel, quartz glass, and ceramic tubes. When preparing or modifying high-purity materials, in order to meet the requirements of material purity, it is strictly required that the materials of the furnace chamber, furnace tubes, boats, etc. in contact with the materials have high purity. In traditional industries, heat-resistant steel is often used as the material for furnace tubes and boats. However, in a high-temperature atmosphere environment, heat-resistant steel is extremely prone to oxidation and corrosion, resulting in excessive impurity elements such as Fe, Cr, and Ni in the high-purity materials processed by the tube furnace, ultimately leading to the scrapping of the materials. When using ceramic materials such as alumina as the materials for furnace tubes and boats, due to the difficulty of making ceramic materials dense enough and the phenomenon of powder falling off in the material itself, it is extremely easy to introduce impurities into high-purity materials.
[0004] At present, quartz tube furnaces are usually used for the preparation or modification treatment of semiconductor high-purity materials, which can avoid the introduction of impurities. The softening point temperature of quartz glass is about 1730 °C, and it can be used for a long time at 1100 °C, and the highest short-term use temperature can reach 1450 °C. Except for hydrofluoric acid, quartz glass hardly reacts chemically with other acid substances. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially its chemical stability at high temperatures is unparalleled by any other engineering material. The thermal expansion coefficient of quartz glass is extremely small, and it can withstand drastic temperature changes. When quartz glass is heated to 1100 °C and then placed in normal-temperature water, it will not crack. However, considering that quartz itself is hard, brittle, and easy to break, it is difficult to achieve industrial automation. In addition, during the use of quartz tube furnaces, generally, powder materials are laid flat in quartz boats, or the materials to be processed are placed in quartz furnace tubes. Since only one boat can be placed, the utilization rate of the furnace space is reduced, and when the length of the furnace tube is long, it is not easy for manual feeding and discharging.
[0005] Therefore, it is very important to solve the problem of waste of space in the tube furnace. Summary of the Utility Model
[0006] Aiming at the deficiencies existing in the prior art, the purpose of the present utility model is to provide a portable loading rack and a tube furnace, which can realize the simultaneous processing of multiple layers of materials, improve the space utilization rate of the tube furnace, and facilitate manual feeding and discharging by using the design structure of rolling sliders, thus saving manpower.

[0036] It should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "set", "connected", "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.
[0037] The technical solution of the present utility model will be further described below in conjunction with the drawings and through specific embodiments.
[0038] In a specific embodiment, the present utility model provides a portable material rack, which includes a support substrate, a rack main body, and at least one towing base. The bottom of the rack main body is movably connected to the support substrate. The rack main body includes at least two loading trays stacked in sequence from top to bottom. Adjacent two of the loading trays are movably connected. The towing base includes a support base and a rolling slider. A positioning chute is formed on the surface of the support base. The rolling slider is slidably disposed in the positioning chute. The rolling slider partially extends out of the positioning chute and supports the rack main body. The support substrate is used to support the rack main body to prevent the multi-layer loading trays stacked in sequence from tilting or collapsing, resulting in the spilling of materials. The rack main body with a multi-layer rack structure improves the space utilization rate, and the number of loading trays can be increased or decreased according to actual production requirements, having high adaptability. And each loading tray can hold different materials or the same materials to meet different experimental requirements. The bottom of the rack main body is supported by the rolling slider and moves along with the sliding of the rolling slider in the positioning chute, which is convenient for manual towing.
[0039] In order to provide better support for the rack body and ensure smooth dragging, the support base of the utility model can be supported by the bottom of the rack body near the edge, and the dragging base is located below the middle of the rack body. A rolling slider is used to press against the middle of the bottom surface of the loading boat at the lowest end, thereby driving the multiple layers of loading boats to move simultaneously.
[0040] It should be noted that the present invention does not specifically limit the active connection method, and any connection method commonly used by technical personnel in the field can be adopted. For example, it can be any one of a snap connection, a buckle connection, a threaded connection, a sliding connection or a rotating connection.
[0041] In some embodiments, the upper surface of the loading boat is provided with at least one limiting groove, and the lower surface of the loading boat is provided with at least one connecting block, and the connecting block is engaged with the limiting grooves of adjacent loading boats. Furthermore, the height of the connecting block is greater than the depth of the limiting groove. The utility model inserts the connecting block of the upper layer of the loading boat into the limiting groove of the lower layer of the loading boat to achieve a movable connection, which is convenient for assembly and disassembly, and there is a gap between two adjacent loading boats to accommodate materials of different forms and avoid contaminating materials. In addition, those skilled in the art can adjust the number of layers of the loading boats and the spacing height of the loading boats according to actual production needs. Specifically, the lengths of the connecting blocks on different loading boats can be the same or different, and those skilled in the art can adjust the specific height of the connecting block to achieve the adjustment of the spacing between two adjacent loading boats.
[0042] In some embodiments, at least one supporting groove is provided on the surface of the supporting substrate, and the connecting block of the loading boat at the lowest end is slidably disposed in the supporting groove. Specifically, the thickness of the supporting substrate is 2 to 20 mm. The utility model inserts the connecting block of the loading boat at the lowest end into the supporting groove, and limits it by the supporting groove to prevent the material rack body from slipping during the dragging process, causing the materials contained in the loading boat to spill. In addition, the height of the connecting block of the loading boat at the lowest end is greater than the depth of the supporting groove, so that after the connecting block is inserted into the supporting groove, a gap is left between the loading boat and the supporting substrate to avoid hindering the dragging operation of the material rack body.
[0043] In some embodiments, the rolling slider is cylindrical. Specifically, the distances from the two side end faces of the rolling slider in the axial direction to the inner cavity wall of the positioning slide groove are independently 2.5 to 3.5 mm. During application, when the material rack is dragged, the cylindrical roller slider rolls along its radial direction, and its circular end faces on both sides along the axial direction are close to the inner cavity wall of the positioning slide groove, and maintain a distance without touching the inner cavity wall, so as to avoid the problem of tilting or offset of the material rack body due to collision.
[0044] In some embodiments, the thicknesses of at least two of the loading boats are the same or different. Specifically, the thickness of the loading boat is 30 - 80 mm. In the present utility model, the sizes, the materials contained, the material capacities, etc. of different loading boats can be the same or different, and those skilled in the art can adjust according to the actual experimental situation, which can not only achieve the processing of a batch of the same material, but also enable the simultaneous processing of multiple different materials.
[0045] In another specific embodiment, the present utility model provides a tube furnace, which includes a furnace body, and at least one portable loading rack as described in the above specific embodiment is arranged in the furnace body, and the support substrate is connected to the inner cavity side wall of the furnace body.
[0046] The present utility model does not specifically limit the connection manner between the support substrate and the inner cavity side wall of the furnace body, and any common connection manner in the art can be adopted. For example, welding can be used.

The connecting blocks 4 are snap-connected to the limiting grooves 5 of the adjacent loading boats 2, which is convenient for fixing and disassembling. The cross-section of the loading boat 2 is square, with a length of 200 mm. The thicknesses of the three loading boats 2 are the same, all being 40 mm. The heights of the connecting blocks 4 are all 15 mm, and the depths of the limiting grooves 5 are all 4 mm, so that there is a gap between the adjacent two layers of loading boats 2 after assembly. The width of the connecting block 4 is 10 mm, the width of the limiting groove 5 is 12 mm, and the distance from the edge of the connecting block 4 to the edge of the loading boat 2 is 25 mm.

The connecting block 4 of the lowermost loading boat 2 is inserted into the support sliding groove for movable connection, so that there is a gap between the support substrate 1 and the lowermost loading boat 2.
[0050] The number of the towing bases 3 is two, which are arranged side by side below the middle of the rack main body. As Figure 4 and Figure 5As shown in the figure, the towing base 3 includes a support base 7 and a rolling slider 8 in the shape of a cylinder. A positioning chute 9 is provided on the surface of the support base 7. The rolling slider 8 is slidably arranged in the positioning chute 9.

A part of the rolling slider 8 extends out of the positioning chute 9 and supports the load-carrying tray 2 at the lowermost end. The sliding of the rolling slider 8 in the positioning chute 9 drives the overall movement of the rack body, facilitating manual towing operation.
