Abstract

PROBLEM TO BE SOLVED: To provide a wide belt device capable of conveying a loading object such as a powder material or a granular material in a planar form with a prescribed, thin and uniform thickness; and to pursue the economical efficiency of the device.SOLUTION: A belt body having a prescribed width in a chain belt conveyor system having a prescribed machine length is formed in such a way that: slats of aluminum or steel with a prescribed width, for example, are provided between left and right chains without gaps or with gaps so as to be arranged in parallel; and at least two long fitting grooves are provided on each slat. In addition, a seal rubber is provided in such a way that: an intermediate part in the width direction of the seal rubber is provided in a form such as an upward-curved semicircular form or a V-shaped form so as to be capable of being expanded and contacted by change in shape; and fitting ribs are provided in a longer direction at both width ends of the seal rubber to join both of the seal rubber and each slat together. Thus, there is formed a gap-free conveyor belt capable of continuously rotatably traveling.

Description

  For example, flat slats made of steel or a rigid material are placed to continuously dry high-temperature moisture and sawdust, or okara, etc. using a far-infrared ray at a low speed with a belt conveyor system. The present invention also relates to a chain belt conveyor that enables continuous running operation without gaps in the load.

  Conventionally, wide belts for conveying powder particles are mainly formed of rubber or resin belts so as to be slidable on the upper surface of a carrier-roller or an iron plate, and are provided with means for preventing meandering, etc. High-cost continuous conveyors were the mainstream. On the other hand, the strip-shaped plate on the chain belt was not able to contain clogging or clogging in the gap between the plates, especially when rotating. It was used for transporting solid materials such as boxes and was not used for transporting powder particles.

  The present invention has been devised by paying attention to the above-mentioned problem, in order to achieve high-temperature drying such as sawdust and okara from high moisture content, it has surface rigidity with an array loading plate made of steel or a rigid flat plate, and Another object of the present invention is to provide a continuously rotating chain conveyor belt capable of following a gap between expanding and contracting to prevent leakage and clogging of a load.

Means for Solving the Problems and Invention

  In order to achieve the above object, according to the present invention, as in claim 1, for example, a granular material having a high moisture content is dried by running at low speed in a room where a high-temperature forced evaporation drying apparatus by far infrared irradiation or the like is installed. A belt body of a chain conveyor having a predetermined width and a predetermined machine length, for example, a plurality of flat plate molding slats such as aluminum steel having a predetermined width are provided in the belt width length, and the belt traveling direction The slats at the time of horizontal running are arranged side by side without any butt-like gaps, and at least two strips in the longitudinal direction of the upper surface of each slat in the width direction. A circular concave fitting pocket is provided, and a stretchable seal rubber is provided so that the intermediate portion in the width direction can be freely expanded and contracted. Arrange This rib is press-fitted and fixed in the rear mating pocket of the front slat and the front mating pocket of the rear slat, and the intermediate part changes its shape when the belt body continuously rotates, and the predetermined length can be sealed following the gap Endless chain belt conveyors can be formed. Alternatively, the slats of the main body can be formed so as to be capable of being press-fitted and fixed by providing fixed pockets in parallel to the left and right chains with a predetermined gap and providing fitting pockets on the end surfaces facing the slats.

  The slat-type chain belt conveyor equipped with seal rubber formed in this way should use a joint with a reduced shape between the slats when the belt body is running horizontally, or a seal rubber that can change the shape when the gap is rotating. When the front and rear ends are fixed and expanded by, for example, the curved seal rubber molded in the upper semicircle of the middle part can be followed and sealed by a gap that expands and contracts due to shape change so that there is no leakage or clogging of the load Can be transported. Accordingly, the conventional chain belt conveyor mainly transports a solid cargo such as a box of a predetermined size. However, as in the present invention, the high moisture content is formed by forming the gaps of the loading plates so that they can be sealed. It can be transported up to sawdust, okara, cigarettes, and even objects that are similar to sludge, and the load is loaded at a flat predetermined thickness and travels at low speed for efficient drying. You can take measures. The slat joint sealing method according to the present invention is a rubber belt or resin that has been widely used in the past in order to enable easy and reliable sealing of the gap by using a both-end-fit seal rubber that can be expanded and contracted due to a shape change. Instead of a belt, for example, by using a molding material such as aluminum steel, the rigidity of the slat itself eliminates the need for conventional carrier-rollers, sliding plates, etc. It can be expected to greatly improve the equipment cost by allowing it to run on a flat surface. Furthermore, the heat drying effect from the bottom surface due to the heat conduction and heat storage of steel can be expected, and a great merit can be brought about. The slat material may be a hard heat resistant resin.

Further, according to a second aspect of the present invention, the slats of the flat-loading plate-mounted chain belt conveyor are fixed in a butt shape without gaps during normal times, and two longitudinal directions are formed on the upper surface as in the first aspect. A fitting pocket is provided. Between the rear and front fitting pockets, a seal rubber with a predetermined width and an intermediate shape formed in a curved shape of an upper semicircle is formed so that both end ribs can be press-fitted and fixed. It is possible to form a chain belt conveyor having no gap between the stacking plates that can be sealed at the joint.
Alternatively, in the present invention, the slats are arranged with a predetermined gap, and a fitting pocket is provided on the front and rear end faces of the slats facing each other, and the shape of the intermediate portion is located between the front and rear fitting pockets A seal rubber provided in a curved shape can be formed so that the ribs in the longitudinal direction at both ends can be press-fitted and fixed, and can be formed so as to be able to follow the gap.

  According to a third aspect of the present invention, a predetermined gap is formed in a comb shape perpendicular to the traveling direction in an infinite circumferential chain disposed on the left and right sides of the chain belt conveyor body having the predetermined length. Between the slats with the mating pockets on the upper surface, or between the slats with the mating pockets on the opposite end faces, seal rubber with ribs at both ends and a V-shaped hook in the center is inserted into the gap The ribs at both ends are formed so that they can be press-fitted into the mating pockets, and when the conveyor body is running horizontally and continuously rotating, the clearance between the slats is expanded and contracted by the change in the intermediate shape of the seal rubber. It can be formed so that it can run without. Further, the seal rubber can be provided with an intermediate portion in a W shape.

  Further, according to the present invention, the slats before and after being arranged in a comb shape perpendicular to the advancing direction on the chain of infinite circumference arranged on the left and right of the chain belt conveyor body of the predetermined machine length as described in claim 4. A seal rubber of a butted shape without gaps, or an upper semicircular curved shape or a V-shaped seal rubber that is arranged with a predetermined gap and expands and contracts by changing the shape of the central part of the mounting, has both ends in the longitudinal direction. It is provided with fins, and the upper surfaces of the front and rear slats are provided flat so that they can be joined and mounted so that they can be continuously rotated without any gaps in the loading plate. This seal rubber with fins can be formed so as to be able to be in close contact with the angle of the forward running slat generated during rotation running and to reduce bending fatigue by initially forming the fins at both ends with a depression angle. .

  Further, according to the present invention, as described in claim 5, the slats arranged in parallel in the chain of infinite circumferential length on the left and right sides of the chain belt conveyor main body of the predetermined machine length that continuously runs are arranged on the front end surface with respect to the traveling direction. A longitudinal fitting pocket is provided, a predetermined rear section is provided with a lower step, a seal rubber is provided with a front fin plate with a rear fitting rib, and the fin plate portion is integrally formed with a depression angle. Thus, it is possible to form a chain belt conveyor with no gap between the flat plate portions that can be slidable in close contact with the upper surface of the adjacent front slats so as to be slidable in close contact with each other. The seal rubber with a single rib with a fin plate formed in this way has a fin plate portion formed with a depression angle so that it can be freely adhered and slidable to the angle of the forward slat during rotation Can be formed. The lower step and the mounting direction of the single rib rubber seal can be reversed and formed.

Effect of the invention

  The present invention is intended to improve the efficiency of drying by establishing a traveling drying system with a predetermined thin wall thickness for particles with a high moisture content in a high temperature drying chamber. The plate is made of heat-resistant steel, or the upper semicircular seal rubber whose shape can be changed by placing rigid slats without gaps, or the V-shaped middle part expands and contracts by providing a gap between the slats By simply fitting and fixing the seal rubber at both ends, it is possible to reliably seal the gap that expands and contracts during normal times and rotations, forming a wide belt that does not require carrier rollers and that does not require meandering prevention measures. The cost can be reduced, and the back surface can be heated by utilizing the thermal conductivity and heat storage property of the slat material, and the drying efficiency can be greatly improved. In addition, it can be said that it is extremely excellent in maintenance and durability.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

    In the present invention, as shown in FIG. 1, a load 1 such as a granular material having a high moisture content is dried in a drying chamber (not shown) by running at a low speed where a high-temperature forced evaporation device using far-infrared radiation is installed. The belt body 2A having a predetermined width of the belt conveyor 2 having a predetermined machine length with a predetermined machine length is a continuous rotation traveling system in which an infinite circumferential chain 3 is arranged on the left and right sides. For example, a flat plate slat 4A made of aluminum steel or the like having a predetermined width is provided in the width of the belt main body 2A, and the stacking plates are arranged in a butt shape A with no interdigital gap in a direction perpendicular to the traveling direction. Are arranged in parallel to each other and fixed to the chain 3, and at least two substantially circular fitting pockets 5A are provided at both ends of the upper surface of the surface of each slat 4A, and the rear part of the normal front slat Mating pocket 5b and rear strap A seal rubber 6 of a predetermined width is provided between the front fitting pockets 5a of the rack, and an initial shape of the intermediate width portion is provided so as to be freely extendable / contractable by changing the shape, and a round bar-like rib 6a protruding at the lower ends of both ends is provided. Thus, the belt conveyor 2 can be formed without gaps in the stacking plate by extending the gap C between the front and rear slats 4A generated during continuous rotation of the belt main body 2A of the conveyor so that the intermediate portion of the seal rubber can follow the shape.

  Accordingly, the conveyor body 2A thus formed has no gap B when the arranged slats 4A run horizontally, and the gap A is enlarged when the slats 4A are rotated, so that the seal rubber 6 is expanded by fixing both front and rear ends. For example, as in claim 2 to be described later, in the initial stage, the intermediate portion is provided in a curved shape of an upper semicircle and travels horizontally in the curved shape, and there is an enlarged gap A between the front and rear slats 4A during rotational traveling. It is possible to form a chain conveyor main body 2A capable of continuously running endlessly without a stacking plate gap provided so as to be able to seal a gap by using a curved seal rubber 6A in which the intermediate curved portion is deformed following the deformation. In the present invention, as shown in FIG. 2, a normal slat 4B can be formed in the same manner by providing fitting pockets 5B on the front and rear end faces with a predetermined interval B and press-fitting a seal rubber rib 6a. I can do it. And although not shown in figure, a hard heat resistant resin can also be used for a slat material.

  The slat type chain type belt conveyor body 2A formed in this way is simply fixed by press-fitting the rib 6a of the seal rubber 6 into the fitting pockets 5A and 5B of the molded slats 4A and 4B as fixed loading plates. The chain-type belt conveyor body 2A, which has conventionally been mainly used for transporting solids, is made of sawdust, okara, cigarette, In addition, it is possible to convey the load 1 that reaches an object similar to sludge, and to provide a drying means. In addition, the present invention uses a rubber seal 6 that can change the shape of the seals of the gaps A, B, and C that expand and contract during the horizontal running of the slats arranged in a comb shape and the rotating running easily and securely. For example, by using aluminum steel or the like for the slat, it is possible to form a conventional carrier roller, a sliding plate, or a plane running that does not require meandering prevention measures with the rigidity of the slat itself. it can. Furthermore, a heat drying effect from the bottom surface due to heat conduction and heat storage of steel can be expected, and a great merit can be brought about. In addition, it can be said that it is extremely excellent in the maintenance of the entire conveyor or the processing measures in the event of trouble as compared with conventional rubber or resin belts.

  In addition, as shown in FIG. 3, the present invention is arranged in an infinite circumferential chain 3 of a predetermined machine length arranged on the left and right sides of a flat-load traveling chain belt conveyor body 2A in a comb shape perpendicular to the traveling direction. A plurality of slats 4A are arranged in a gapless A, and as shown in claim 1, fitting pockets 5A are provided at almost both ends of the upper surface to fix them to the chain, and the front and rear slats 4A are fitted together. A rib 6a provided at both ends in the width direction of an upward curved semicircular curved sealing rubber 6A whose shape can be changed in the middle is press-fitted and fixed in the pocket 5A so that the stacking plate gaps A and C can be continuously rotated. A chain conveyor belt 2 can be formed. Alternatively, as shown in FIG. 2, the adjacent slats at normal times are arranged with a predetermined gap B, and the end pocket is provided with a fitting pocket 5B, and the intermediate part shape variable seal rubber 6A is formed. Can be used to form the mating slats 4A, 4B array type conveyor 2.

Adjacent slats 4A with mating pockets 5A are fixedly arranged with a predetermined gap B, seal rubber 6B is provided in an intermediate V shape, and ribs 6a are provided in the longitudinal direction of the back surface at both ends in the width direction to provide rear portions of the front slats. When the conveyor body 2A runs horizontally and rotates, the seal rubber is increased as the distance between the front and rear fitting fixing ribs 6b increases. 6B can be easily extended and contracted so that it can run without gaps B and C between the slats. The V-sealed seal rubber is effective when the expansion and contraction is large. The intermediate portion can be formed in a W shape. In addition, a fitting pocket 5B can be provided on the end surface of the slat 4B.
