Abstract

PURPOSE:To make it possible to manufacture a heat-resistant chain conveyor with the use of refractory materials, etc. which are difficult to be fabricated, by forming, in both end parts of each joint shaft, grooves each adapted to receive two peices of chains, and by fitting, in each groove, the chain pieces each having an elongated hole adapted to slide along the groove. CONSTITUTION:A joint shaft 12 is formed, in its each end, with a groove 14, 16 having a width 21 and a depth DELTAR, in which two pieces of chaines 10 having length (l) may be fitted. Then, two chain pieces 10 each defining therein a center hole 26 having a diameter D equal to that of the joint shaft 12 and two elongated holes 20, 22 adapted to be slidably fitted onto the joint shaft 12 are fitted into the groove. The chain pieces 10 are attached to the joint shaft 20 by means of a guide rail 30 to be guided therealong. With this arrangement, the conveyor having a simple structure may be formed with the use of ceramic materials or the like which are difficult to be fabricated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat-resistant conveyor that has a simple structure and can be constructed of a high-temperature refractory material that is difficult to process.

Carbon fiber, which is attracting attention as a cutting-edge material these days, is manufactured or reinforced using oxygen-free temperatures of 1500℃ to 3000℃.
℃ is required, and there is a need for continuous transfer heat treatment of carbon materials in an inert gas atmosphere furnace at this high temperature for mass production. Because it is brittle, it is difficult to make delicate mechanisms such as screws, and it is difficult to make it into a flexible and slidable device like a conveyor, so the Hikosho On Conveyor as mentioned above was not possible.

In order to overcome this difficulty, the present invention constructs a conveyor in a simple shape that can be molded from refractory materials, carbon, graphite, ceramic, etc., which are hard and brittle and difficult to make precise element screws, and is a heat-resistant conveyor. was provided. For this purpose, the joint shaft of the conveyor is made into a simple cylindrical shape with a diameter of 21 mm, which can accommodate 72 pieces of thickness e near both ends.
A groove with a rectangular cross section of depth ΔR is formed, and a round hole at both ends of the diameter that slides into the diameter D-2ΔR of the concave groove on this shaft, and a long hole connected by a groove with a width of that diameter. A hole with an outer diameter D=i of the joint shaft is made in the middle, and a simple chain is made with a thickness such that two chinos can fit into the groove of each joint shaft, and a hole in the center through which the joint shaft passes through the two chinos is made. After passing the shaft through the hole, place it separately at the end of the long hole groove of the chino, and after assembling the adjacent chino and joint shaft, simply keep the chino in the concave groove of the joint shaft by applying tension. To construct a heat-resistant conveyor device by preventing the chino from coming off from the joint shaft groove, and by making a guide for guiding the chino into a simple shape and made of a heat-resistant material.

Since this device has a simple shape, it is possible to form a conveyor using any heat-resistant material that is difficult to process, so it can fully perform its transfer function even at high temperatures, and can also contribute to the development of advanced materials.

Preferred embodiments will be described below with reference to the drawings.

Fig. 1 is a sectional view perpendicular to the direction of movement of a chino in which two pieces of left and right chenos 10 are connected at the same time by one joint shaft 12. The width 2I is twice the thickness k of the chain that overlaps and slides the front and opposite ends of two pieces of the same shape chaino 10 together! It has shaft grooves 14 and 16 with a rectangular cross section and a depth ΔR.

As shown in FIG. 2, the single piece of chino 10 that fits into this groove has the same shape and thickness l, and has front and rear circular holes 20, 22 at both front and rear ends with a diameter D-2ΔR that slides into the shaft groove 16 of the joint shaft 12. A through groove 24 having a diameter equal to the diameter of the hole connecting the outer diameter of the connecting shaft 12 and a hole 26 which fits around the outer diameter of the joint shaft 12 is provided in the middle of the groove. To assemble a chino using this joint shaft 12 and the chain 7l0, insert a hole 26 that fits in the middle shaft diameter of the through groove 24 of each two chinos 10, and insert the shaft groove 1 beyond both ends of the joint shaft 12.
6 and 18, and shift them in opposite directions as shown in Fig. 3, and align the front hole 20 at the end of the inner chino and the rear hole 22 of the outer chino with the axial grooves. 16
18, the grooves 16° 18 of the two front and rear joint shafts adjacent to the joint shaft 10 are engaged repeatedly with the inside of each outer front hole 20 turned into the rear hole 22, and the tension is applied after assembly. In addition, it prevents the chino 10 and joint shaft 12 from coming out. Such a conveyor chain is placed on a simple guide rail made of a heat-resistant material having guide edges 32 at both ends as shown in FIG. 1, for example, and guided in the direction of movement of the chain.

According to this method, the conveyor has a simple structure and does not require precise mechanisms such as screws, so it can easily be constructed from refractory materials such as reinforced carbon, graphite, and ceramics, which are difficult to process, to provide a heat-resistant conveyor.

On the upper side, the joint shaft has a consistent diameter, but both ends of the shaft groove of the joint shaft, which overlaps the holes 20 and 22 on the front and rear of the chino, are larger than the diameter D-2ΔR of the sliding holes 20 and 22 on the chino. Other than the inner and outer diameters of the groove that regulates play in the axial direction of the joint shaft, the intermediate diameter of the joint shaft and the outer shape of the chino are free.
