Abstract

PURPOSE:To prevent conveyance materials from slipping off a belt by deforming an upper side flanged belt in a slant part into a shape having a bag-like cross section, engaging seal ear parts while push-pressing both upper outside edges by means of seal rollers, and wrapping the conveyance material in while supporting the lower part from below with push-pressing rollers. CONSTITUTION:A flanged belt 24 in a slant part is introduced into a space between both side seal rollers 13a and 13a', push-pressing rollers 13b and 13b' and the upper and the lower fixed guide rollers 14a and 14b in a support roller device 11. Seal ear parts 21a and 21b are push-pressed in a space between the seal rollers 13a and 13a', and a recessed groove 22 and a projecting strip 23 are engaged so as to form a cylindrical shape. Thereby, the belt can wrap particulate in the cylindrical shape part, and is push-pressed from the right and the left sides by means of the lower part push-pressing rollers 13b and 13b', and can convey it while being supported from below with a lower guide roller 14b. In this way, the particulate is put under a sealed condition so that it can be conveyed without slipping off the belt.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an inclined belt conveyor for transporting powder and granular materials that prevents the powder and granular materials from sliding down on the inclined portion.

[Prior Art] Conventionally, as shown in FIG. 4, a belt conveyor for transporting powder and granular materials is provided with belt pulleys d at both ends of a conveyor frame C having a horizontal portion a or an inclined portion.
Carrier rollers e are disposed on the upper surface of the conveyor frame C between d at predetermined intervals in the longitudinal direction, and return rollers r are disposed on the lower surface of the conveyor frame C at predetermined intervals in the longitudinal direction. Then, an endless annular belt 9 is passed over the carrier roller e and the return roller r, and is passed between the belt boots 9d, and the transport material is placed on the belt 9 on the carrier roller e side, and the belt 9 is continuously By rotating in the direction, the transported goods are transported.

[Problem to be solved by the invention] However, the above-mentioned belt conveyor for transporting powder and granular materials has the following problems:
When the slope shown in Fig. 4 is provided, if the slope angle is set above a certain level (for example, about 16° for coal of uniform size), the transported material will slide down on the belt Q. Problems include falling and accumulating under the belt conveyor, reducing the conveying capacity of the belt conveyor, and because the inclination angle of the belt conveyor cannot be increased, the horizontal distance of the belt conveyor becomes longer than the required lifting height. There is.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an inclined belt conveyor for transporting powder and granular materials, which prevents transported objects from sliding down the belt even if the inclination angle of the belt conveyor is large. .

[Means for Solving the Problems] The present invention has a sealing ear that has an endless shape and has continuous grooves and protrusions that can be engaged with each other at both ends of the outer peripheral surface in the width direction. A flange belt formed by the above is arranged on a conveyor frame so as to form an inclined part, and a flange having a bag-shaped cross section is formed by engaging the concave grooves and the protruding strips on the upper part of the flange belt in the sloping part. A holding roller device having a sealing roller that presses the sealing ears of the attached belt against each other and a pressing roller that presses the outside of the bag-shaped portion is arranged on the conveyor frame at a required interval, and A powder particle characterized in that a receiving roller device having a carrier roller having a predetermined trough angle and a side roller that abuts both width ends of the flange belt is disposed at front and rear positions in the traveling direction of the flange belt on the inclined part. This relates to an inclined belt conveyor for transporting bodies.

When the inclined belt conveyor is started, the flange belt 24 rotates between the drive pulley 5 and the tail pulley 8.

The flange belt 24 leaving the tail pulley 8 and attempting to pass through the receiving roller device IB provided on the tail side horizontal portion 3 of the conveyor frame 4 is supported by the carrier rollers 18a, 18b of the receiving roller device 16 and passes through the side rollers. 19, the sealing rollers 13 on both sides of the holding roller device 11 provided on the inclined part l of the conveyor frame 4
a, 13a', pressure rollers 13b, 13b', and upper and lower fixed guide rollers 14a, 14b.

The flange belt 24 guided to the holding roller device 11 has its seal ears 21a and 21b on both sides sandwiched between the upper seal openings 13a and Ila', and the spring 1
Due to the repulsive force of 2, the concave grooves 22 provided on the seal ears 21a, 21b and the protrusions 23 reliably engage, forming a cylindrical shape. The lower bag-shaped portion 25 of the cylindrical flange belt 24 is
Pressed by lower pressing rollers 13b and 13b',
It is supported by a fixed guide roller 14b provided at the lower part of the center of the frame 10 in the width direction, and is further supported by a fixed guide roller 14a provided at the upper part of the center of the frame 10 in the width direction.
, 21b passes through the plurality of holding roller devices 11 while being guided by the end face.

The flange belt 24 passes through the holding roller device 11 and then reaches the receiving roller device 20 provided on the horizontal portion 2 on the head side of the conveyor frame 4.
The engagement between the concave grooves 22 of a and 21b and the protrusions 23 is released, and the carrier rollers 18a and 18 provided on the receiving roller device 20 are released.
b while being guided by the side rollers 19 and rotating in the direction of the drive pulley 5.

When the transported object is supplied onto the flange belt 24 on the horizontal portion of the tail side of the inclined belt conveyor by a chute (not shown), the flange belt 24 becomes bag-shaped in cross section as described above, and the transported object 26 The conveyor frame 4 ascends the inclined part 1, and at the horizontal part 2 on the head side of the inclined belt conveyor, the flange belt 24 returns to its normal state as described above, and the transported object 2B is discharged from the drive pulley 5 section. .

The surface of the flange belt 24 that is soiled with a portion of the transported object 26 is cleaned by scraping off the deposit with a scraper 27 provided near the drive pulley 5.

According to the above, the flange belt 24 having a bag-like cross section at the inclined portion 1 of the conveyor frame 4 wraps the transported object 26, thereby reducing frictional resistance between the transported object 26 and between the transported object 26 and the flange belt. Since the frictional resistance between the belts 24 is increased, it is possible to prevent the transported objects 26 from slipping off on the inclined belt.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

[Effects of the Invention] As explained above, according to the inclined belt conveyor for transporting powder and granular materials of the present invention, the flange belt transports the object, wraps it, seals it with the sealing roller, presses it with the pressing roller, etc., and transports it. By increasing the frictional resistance between objects and between the objects being transported and the flange belt, it is possible to completely prevent objects from sliding down on the belt of the inclined belt conveyor, and to prevent objects from sliding off the belt conveyor. It is possible to prevent the transported objects from falling and to maintain a stable conveyance amount on the belt conveyor at all times. Furthermore, since the inclination angle can be set large, the horizontal distance of the belt conveyor can be shortened, which can bring about various excellent effects such as being economically useful.
