Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a belt support device for a steel belt cooler.

[Prior art] In a steel belt cooler, steel belts of the required width and length are connected in an endless manner, and a GV is installed at both ends of the inner surface and, if necessary, at the center.
The ropes are joined, a V-sheave is attached to this GV rope, and at least one of the V-sheaves is driven, and a refrigerant is injected from the back of this steel belt to cool the material conveyed by the steel belt as desired or to inject hot water. I try to warm it up.

[Problems to be solved by the invention] Therefore, a GV rope connected to the back of the steel belt is used to regulate and drive the steel belt, but when this GV rope is connected to the steel belt, the V The distance between the GV ropes is determined in advance to match the sheave interval. However, it is difficult to join accurately, and tolerances are determined depending on the belt width.

When this steel belt is driven while being guided by the V-sheave, when the belt meanders and the belt bends at the V-sheave position and bending position, the contact between the GV rope and the V-sheave becomes uneven, and the GV rope becomes uneven due to long-term use.
Rope wears out. Since this GV rope also serves as a drainage seal for the upper cooling water, wear of the GV rope causes poor sealing performance and water leakage. For this reason, in the past, water leakage due to GV rope wear was assumed in advance, and an extra drainage device was sometimes installed to suck and drain the cooling water leaking to the outside of the GV rope. However, drainage outside the GV rope is not reliable, and sometimes some of the water leaks into the object to be cooled, degrading quality or causing unexpected accidents.

In addition, in double steel belt coolers, the belts are pressed and supported at a predetermined distance so that the thickness of the articles transferred between the belts is uniform, but the articles being fed are If more or less than a certain amount is supplied unevenly at one time, the sheave pressing the belt alone may not have enough pressing force, or the belt may become distorted in areas where there is no sheave, making it difficult to clamp objects of uniform thickness. Cannot be transferred.

[Means for solving the problem] In order to achieve the above object, at least two parallel GV ropes are connected relatively close to each other and parallel to both ends of the back surface of the steel belt.
A drum that is in contact with the back side of the steel belt and supports the belt is arranged between the inner GV ropes that are opposite to each other among the GV ropes.
A suction nozzle for cooling water drainage is installed between the GV ropes, and the tip of this drainage nozzle is connected to both the internal and external GV ropes.
Close to the back of the steel belt between the ropes.

[Function] Of the two GV ropes provided at both ends of the back of the steel belt, the opposing inner GV
The drum between the ropes prevents the steel belt from meandering, and even when pressurizing objects to be cooled or heated at a constant pressure, the back of the steel belt can be kept flat across the entire surface by its support. Supported, the belt will not be distorted, and both internal and external GV
The arrangement of drainage nozzles between the ropes allows the friction of the GV rope to be extremely controlled, extending the life of the GV rope and improving the watertightness of the rope.

[Example] A belt support device for a steel belt cooler according to the present invention will be described with reference to an example shown in the drawings.

In the steel belt cooler A, the steel belts S1 and S2 are endless belts having the required width and length and are strung vertically (or one belt in the case of a single cooler).
1. S2 are arranged so that their outgoing paths face each other from above and below, and the lower steel belt S1 is placed on the back side of the steel belts S1 and S2, that is, on the opposite side that supports the object to be cooled, from the spring truss 4. Regarding the belt S2, cooling water and other refrigerant are injected from the spray nozzles 5, respectively, to cool the object to be cooled via the steel belt. For this reason, the back surfaces of the steel belts S1 and S2 are supported by drums 2 and 3 at least at both ends of the steel belts.
In this method, a drum 2 is arranged between the inner GV ropes 11, 11 which are opposite to each other among the GV ropes 11, 11, 12, 12, which are attached in parallel on both sides of the back surfaces of the steel belts S1, S2. and support. In this case, the end surfaces of the drum 2 are brought into contact with or close to the inner surfaces of the GV ropes 11, 11, so that the steel belt is driven while being prevented from meandering.

Cooling water and the like injected from the spring truss 4 onto the back surface of the upper steel belt S1 flows downward along the inclination of the belt. Then, a drainage weir 6 for removing the cooling water flowing down along the back surface of the steel belt is provided below the endless steel belt, for example, near the supporting portion of the drum 2, or a suction nozzle is arranged close to the back surface of the steel belt. to prevent leakage from the GV rope 12 to the outside. However, the cooling water, etc. that could not be drained at this drainage weir is removed from the inner GV rope 11.
When the water reaches a certain level, it overflows from the inner GV rope 11 and flows out between the inner and outer GV ropes 11 and 12. A discharge suction nozzle 7 is provided to drain this outflow water. The tip of this suction nozzle 7 is close to the back of the steel belt between the GV ropes 11 and 12, so that the cooling water leaking from the inner GV rope further flows out to the outside from the outer GV rope. It will be drained like this.

[Effects of the invention] The belt support device of the steel belt cooler of the invention connects two parallel GV ropes relatively close to each other on both ends of the back of the steel belt, and connects two parallel GV ropes to each other, and A drum is placed between the GV ropes, in contact with the back of the steel belt, and supports the belt.The drum supports the steel belt, and a suction nozzle for cooling water drainage is installed between the inner and outer GV ropes. In addition, the tip of this drainage nozzle is located close to the back of the steel belt between the inner and outer GV ropes, so that the opposing steel belts can be uniformly supported over their entire width at the pressing part, allowing the goods to be Even when pressing force is applied to the belt, the belt can be compressed and transferred at an accurate thickness without being distorted, and the cooling water can be reliably drained, preventing cooling water from leaking from the belt side edge, improving product quality, etc. There are advantages.
