Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a cooling machine in which two endless steel belts are stretched facing each other to cool a material to be cooled while sandwiching and transporting the material. This invention relates to a double belt type cooling machine that enables uniform cooling.

[Conventional technology]

As a method of cooling substances with high viscosity and poor fluidity such as chemicals, foods, industrial raw materials, and paints, the above materials are rolled almost uniformly on an endless belt.
A belt type cooler has been proposed that cools the steel belt by cooling the back side thereof.

[Problem to be solved by the invention]

However, as a method of uniformly rolling the material onto this steel belt, there is a roller rolling method in which the material is supplied from a feeder installed above the belt and is rolled by rolling rollers that face each other in the front and back, and then is supplied onto the steel belt. There is a press roller type in which the belt is sandwiched between press rollers from above and below, and the material supplied from the feeder is rolled between the press rollers and the steel belt. However, when a roller with which the material comes into direct contact with the steel belt is used in addition to the steel belt, the material adheres to the rolling roller in the case of a highly viscous material, making it necessary to frequently clean the roller.

Possible methods to prevent this adhesion include cooling water to a low temperature by pouring cooling water into the inside of the press roller, or applying Teflon coating, silicone rubber coating, or sand-plus treatment to the press roller surface, but none of these methods may cause damage to the equipment. It is complicated and expensive, and also has the disadvantage that it cannot reliably prevent adhesion.

Examples of substances that have the property of being sticky at temperatures above a certain level, but disappear after cooling, and easily peel off from steel belts, etc. are cheese, sorbitol (food additive), rice cakes, etc. We aim to provide a double steel belt type cooler suitable for rolling cooling.

[Means to solve the problem]

This cooling machine has two endless steel belts arranged at the top and bottom, and the material is rolled and conveyed by the forward side of both belts, and the material is cooled from the back side of both the upper and lower belts to achieve the desired material cooling. The rollers on which the belts are hung, which are disposed at the material supply side ends of the upper belt and the lower belt, are made to face each other laterally, and the belts that are hung on both rollers are formed in two strips so as to form a hopper shape between the rollers. The belts are arranged so as to be in contact with each other, and a feeder for supplying material is arranged between the belts in the hopper-like upper part between the rollers, and a weir plate is provided at the side position of the two belts between the rollers. Become.

〔Example〕

The present invention will be explained below based on the illustrated embodiments.

In the figure, 1 is a steel belt made of stainless steel or the like having the required width and length, and the upper belt 1a and the lower belt 1b have the same width, but their total lengths are the same or different. Rollers are disposed facing each other at both ends of the (endless) belt, and the steel belt 1a or 1b is stretched between these rollers. In this case, as shown in FIG.
They may be horizontal and parallel, or they may be arranged parallel to each other with one end raised, as shown in FIG. 2, or they may be arranged in a stretched manner depending on the purpose.

The forward side of each of the upper and lower belts 1a, 1b facing each other is driven in the same direction and at the same speed, and in the case of a horizontal arrangement, the central part of the forward side is raised slightly upward. This makes it easier to recover the cooling water that is injected onto the back surface of the curved upper belt on the forward path side.

Sprinkle troughs 4 for spraying cooling water evenly in the cross-sectional direction of the belt are provided at a desired interval from one to two or more on the back surface of the upper belt 1a on the outbound side. If the steel belt is stretched horizontally as shown in Figure 1, the belt should be placed at a position slightly raised from the other part in the middle of the belt on the outgoing side, and if it is slanted as shown in Figure 2, it should be placed at the end of the belt on the outgoing side. Sprinkle troughs 4 are provided in the upper and middle portions, and the number of sprinkle troughs to be installed is determined in consideration of the overall length of the steel belt, the degree of cooling, the belt speed, the properties of the object to be cooled, etc.

The sprinkles are then sprayed onto the back surface of the steel belt from the sprinkle trough 4, flow down the back surface of the belt in a lower direction while exchanging heat on the belt surface, and are placed at a predetermined position and in contact with or close to the back surface of the belt. Water is collected and discharged at the water collection weir 5. Like the sprinkle trough, this water collection weir 5 also has approximately the same length in the cross-sectional direction of the belt, that is, in the belt width direction.

The upper belt 1a is provided with rollers 2 and 3 at both ends thereof, and the lower belt 1b is provided with rollers 6, 7, and 8 at both ends thereof, and the rollers 2, 6, and 3 are in contact with each other. This roller 2,
Between 3 and 6, 8, the two belts 1a, 1b are configured to move facing each other with a required spacing between them. The roller 7 is used for tension.
A feeder 9 is provided at a position above the two opposing rollers 2 and 6, and material is fed between the belts 1a and 1b between the rollers 2 and 6. The belt between the rollers 2 and 6 has a V-shaped hopper shape, and the material supplied by the belt drive is naturally rolled and held between the belts, and is transferred from the rollers 2 and 6 side to the hopper. , 8 side, and desired cooling is performed during this transportation.

In the drawing, reference numeral 10 denotes a weir plate, which is provided opposite to both sides of the roller ends so that the width is slightly smaller than the width of the belts 1a and 1b hung on the rollers 2 and 6.The material fed from the feeder is placed on the sides of the roller ends. To prevent the object from escaping and to ensure that the object is held and conveyed between the belts 1a and 1b. A drive device 11 drives the rollers 8, 3, etc., and drives the belts 1a, 1b.

〔Effect of the invention〕

According to the present invention, a highly viscous material is directly supplied between the two belts each having a V-shaped hopper opening at the end, and the weir plate prevents the material from flowing out to the side, unlike the conventional method. It is possible to omit a press roller, etc., and there is no need for the material to adhere to the press roller, etc., or to take measures to prevent it from adhering.The material is rolled and held between the upper and lower belts and cooled while being conveyed. When the material is removed, it is naturally and reliably peeled off from the belt surface, and the equipment is simpler than conventional methods, and continuous operation for supplying a fixed amount of material can be reliably performed without various problems caused by material adhesion.
