Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an air-permeable metal wire conveyor belt for performing scouring, cleaning, dehydration, drying, heat treatment, and freezing of substances during the conveyance process. .

(Prior art) Conventional conveyor belts made of metal wire that perform this type of water filtration function have been designed to prevent the belt from shifting when traveling between rollers (belt wheels) in a conveyor device. Sensors installed on both sides of the belt electrically detected unbalanced running, and this was transmitted to the roller (belt wheel), which moved the axis to correct the belt's unbalanced running. However, although this correction method is relatively effective when the distance between the rollers (belt wheels) is large (long belt), it takes a considerable amount of time to completely correct the rollers (belt wheels).
The unbalanced tension caused by swinging the axis of the belt causes the belt structure (metal wire) to become distorted or unnecessarily stretched, causing irreversible distortion in the belt itself, which further causes unbalanced running, a vicious cycle. It was the cause of

In particular, in the case of belts used for compressing and dewatering work where the distance between rollers (belt wheels) is short (short belts) and high tension is applied, the belt may be offset relative to the swing angle of the rollers (belt wheels). At present, the effect of the modification was extremely small, and almost no effect was obtained.

(Problems to be Solved by the Invention) The metal wire conveyor belt of the present invention uses a metal wire conveyor belt having water filtration properties in order to essentially eliminate the uneven running that has conventionally occurred during driving. The belt is constructed so as to be engaged with a roller (belt wheel) along its length, thereby preventing the belt from running lopsidedly.

(Means for Solving the Problems) For this purpose, the metal wire conveyor belt of the present invention has a structure in which a flexible belt body made of a textured material made of metal wires has a structure in the direction of its length. This problem can be solved by filling a molten hard elastic material in the shape of a crosspiece along the curve and hardening it to lay one or more foundation strips, and then integrally arranging the guide claws on the back side of the foundation strip.

Next, as a conveyor device, the belt body is stretched over a roller (belt wheel) provided with a receiving groove that fits the guided pawl portion of the belt body, and the guided pawl portion is placed in the receiving groove of the roller (belt wheel). It is characterized by a metal wire belt conveyor device that runs in tandem with the conveyor belt.

In addition, as a method for protruding guided pawls on a metal wire conveyor belt, a low thermoplastic oil-based material is melted along the length of the metal wire belt body having an air permeable (filtration) texture. A mold is formed by filling and hardening it as a set of two frame wall strips spaced apart from each other, and between the frame wall strips, a template is placed on the front side of the tissue fabric and a row of punched holes are provided on the back side. A formwork is formed by placing the plates across each other, and by injecting and filling the molten hard elastic material into the formwork and hardening it, a bar-shaped base strip and a guide claw part are formed on the back side of the base strip on the belt body fabric. A conveyor belt made of metal wire is manufactured through a step of integrally forming and arranging the metal wires, removing each of the templates, and melting and removing the frame wall strips at a low temperature.

(Function) A portion along the length of the belt body structure made of metal wire and bending along the length (frame-like)
By arranging guided pawls on the back side of the base strip, which is prepared by filling and hardening a molten hard elastic material, the belt is driven while the guided pawls are engaged with a roller (belt wheel). This works to prevent the belt body from meandering.

The guide claws of the base strip, which is filled and formed to implant tissue over a wide range along the length of the belt body, are integrated with the base strip supported in a hair-like manner by each metal wire tissue material of the belt body. It is formed with an extremely strong support protrusion.

In addition, the base strip, guided claw portion, and fixed strip can adapt well to the bending fluctuations of the belt body tissue due to the hard expansion and contraction action of the hard elastic material, and can absorb this variation. The strong tension created by embedding and fixing each part prevents the metal wire of the belt structure from stretching unnecessarily and shifting.

Next, in order to inject and fill a portion along the length of the belt body, which is flexible along the traveling direction of the metal wire, a molten hard elastic material is injected and filled at a low temperature using a low thermoplastic oil-based material that hardens rapidly at room temperature. By utilizing its melting properties to form frame wall strips that are part of the formwork, the molten hard elastic material is tightly infiltrated into the continuous cavities between the metal wire materials stretched in a spider web pattern. The metal wire material can be easily implanted and filled, and the frame wall strip can be easily melted and removed by low temperature treatment after hardening of the hard elastic material, and the length of the belt structure can be By injecting and filling a portion along the direction with a molten hard elastic material, it is possible to connect the base strip and the guided pawl.

(Example) Specific examples of the metal wire conveyor belt according to the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a belt body, in which metal wires made of stainless steel, iron, light metals, non-ferrous metals, and other arbitrary metals are formed into flat spiral entangling rods 2a and linear connecting rods 2b. And this entangling rod 2
a, 2a are arranged in parallel in sequence, the bent parts are interlaced, and the connecting rods 2b, 2b are respectively inserted into the inside of each bent part, and each end part is fixed to each other by entangling, welding, etc., and the whole is made up. It is connected in a flexible band shape. Near the center of the texture along the length of the belt body 1, a naturally hardening type or vulcanization hardening type hard elastic material such as molten synthetic resin, rubber, polyurethane, etc., is wear-resistant, heat-resistant, and corrosion-resistant. Guided claw portions 4, 4 are integrally arranged in a protruding row on the back side of two bar-shaped foundation strips 3, 3, which are filled and hardened and laid at an appropriate distance from each other. The guided pawls 4 are arranged in a row so that they can turn when the belt body 1 is stretched around each roller and driven. The block is formed into any shape such as a column or cylinder, and the number of foundation strips 3 and the number of guided pawls 4 to be laid are arbitrary depending on the width, length, etc. of the belt body 1. Further, it is also possible to strengthen the guided claw portion 4 by protruding a part of the spiral of the entangling rod 2a, which corresponds to the guided claw portion 4, and filling it as a core material to form the guided claw portion 4. . Reference numeral 5 denotes a fixing strip made of a hard elastic material, which is formed by filling and hardening the fabric of the left and right fixing sides 1a, 1a along the length direction of the belt body 1.

Reference numeral 6 denotes a driving roller (belt wheel) in a basic conveyor device, in which the belt body 1 is connected and stretched in an endless ring between an opposing driven roller (belt wheel) 7, and the belt is Each of these rollers 6, which maintains the body 1 in tension,
7 and 8 are receiving grooves 6 that fit the guided claws 4 and 4 of the foundation strip 3 laid on the belt body 1 and guide them normally.
a, 7a, and 8a are provided. FIG. 7 shows a belt body 1 as a belt press used in a compression dehydration separation device, and 9 and 10 are rollers (belt wheels);
Numeral 11 is a pressure roller, and 12 is a main drum (driving drum). The muddy water supplied from the feed box 15 is filtered by the lower filter cloth belt 13 while being sent between the upper filter cloth belts 14 and brought into tight contact with the surface of the main drum 12. It is compressed and dehydrated in one part of the belt body and separated as a dehydrated cake.

Figures 8 and 9 show the process of laying the cross-shaped basic strip 3 together with the guided pawl portion 4 on the fabric of the belt body 1, in which a low thermoplastic oil-based material such as melted paraffin is applied to the belt body. A pair of frame wall strips 16, 16 is formed by pouring and hardening two parallel strips on the left and right at appropriate intervals along the length of the fabric of the first fabric, and forming a pair of frame wall strips 16, 16. A template 17 is placed on the tissue surface side between 16 and 16, and a punch hole 19 is placed on the back side.
The mold plates 18 on which the molds 19 are arranged in rows are each placed side by side and fixed to form a mold frame, and the mold plates 18 are turned upside down so that the upper surface is exposed. After injecting and filling the material and allowing it to spread from the inside of the tissue to the front and back surfaces and harden,
By removing the templates 17 and 18 of the formwork and melting and removing the frame wall strips 16 at a low temperature, a bar-shaped foundation strip 3 is formed along the length of the textured metal wire portion of the belt body 1. It is formed integrally with the guided claw portion 4.

(Effects of the Invention) The metal wire conveyor belt of the present invention is made by filling and hardening a molten hard elastic material into a countless number of continuous belt textures made of metal wire so as to bend along the length direction. By providing a base strip in the shape of a crosspiece along the length and a guide claw part that protrudes integrally with this, the guide claw part made of a material different from the metal wire of the belt can be attached to the base of the belt structure. It is integrally formed and supported by a bar-shaped foundation strip that is filled and infiltrated in a hair-like manner, and a strong connection structure that does not easily separate and break even under guided forcing force is obtained.

Moreover, since the belt textured metal wire is wrapped and fixed in an embedded manner with the base strip and fixed strip made of hard elastic material, distortion and deviation of the textured metal wire caused by strong tension on the belt is suppressed. This makes it possible to reliably prevent damage and deformation of the belt due to this, and also ensures smooth belt running by adapting to the belt body without hindering its flexibility due to the hard expansion and contraction action of the hard elastic material. can do.

In particular, in the present invention, guided pawls arranged in rows along the length of the belt on the back side of the belt made of a metal wire that bends in the length direction are engaged with rollers (belt wheels) in the conveyor device. By running the belt in a driven manner, the guided claws of the belt are guided by the receiving grooves of each roller (belt wheel), eliminating belt meandering itself. It is extremely effective for conveyor belts made of metal wire or metal wire conveyor belts that are subject to very strong tension. moreover,
It does not require complicated mechanisms such as the conventional meandering detection device and the roller (belt wheel) axis center adjustment device that is linked to it, and also has the effect of eliminating the time loss from meandering detection to complete alignment. .

In addition, a molten hard elastic material is partially injected and filled into the network-like structure of the belt in the form of a rail to create a foundation strip.
To form the guided claw part/fixing strip, by utilizing the properties of the low thermoplastic oily material, we can melt and inject the low thermoplastic oily material on the adjacent side, and create countless cavities that can be continuous with its fast hardening properties. A partition frame wall strip is formed in the tissue having a partition frame wall strip, which facilitates and reliably injects and fills the molten hard elastic material into the tissue surrounded by the formwork consisting of this and a template. The partition frame wall strip that has been infiltrated and sealed into the tissue fabric can be melted and removed using low-temperature treatment without affecting other parts, so the base strip and guide nails can be placed in appropriate locations in the belt fabric. Sections and fixed strips can be firmly planted.
