Description

Technical Field

[0001] This utility model belongs to the field of rock wool production technology, and specifically relates to a cooler for rock wool production. Background Technology

[0002] Rock wool is a type of rock wool produced using high-quality basalt, dolomite, and other raw materials as main materials. After melting at temperatures above 1450℃, the fibers are centrifuged at high speed using an internationally advanced four-axis centrifuge. Simultaneously, a certain amount of binder, dust-proofing oil, and water-repellent agent are sprayed in. The fibers are then collected by a cotton collector, processed using a pendulum method, and then cured and cut using a three-dimensional method to form rock wool products of different specifications and uses. A rock wool production cooler is an auxiliary device used to cool and solidify the produced rock wool, facilitating subsequent cutting. It is widely used in the rock wool production field. For example, patent CN210532823U discloses a rock wool production cooler that can only cool the top surface of the rock wool with airflow. The cooling effect on the sides, especially the bottom surface, is poor, resulting in poor cooling uniformity, low cooling efficiency, and limited practicality. Summary of the Invention

[0003] In order to overcome the problems of the prior art which can only cool the upper surface of rock wool by blowing air, and has poor cooling effect on the sides of rock wool, especially the bottom surface, poor cooling uniformity, low cooling efficiency, and poor practicality, this utility model provides a cooler for rock wool production.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A cooler for rock wool production mainly includes a frame 1, a cooling chamber 2, an air distribution chamber 3, a conveying roller 4, an air supply pipe 5, a refrigeration box 6, and a fan 7. The cooling chamber 2 is installed on the frame 1, and the air distribution chamber 3 is installed at the bottom of the cooling chamber 2. The bottom of the cooling chamber 2 is provided with a horizontal elongated air inlet 21, and the cooling chamber 2 and the air distribution chamber 3 are connected through the horizontal elongated air inlet 21. Conveying rollers 4 for conveying rock wool are evenly installed at the bottom of the cooling chamber 2. Rock wool inlets and outlets are provided at both ends of the cooling chamber 2, and the air supply pipe 5 is connected to the bottom of the air distribution chamber 3. The air supply pipe 5 is connected to the refrigeration box 6 and the fan 7 in sequence.

[0005] Furthermore, guide vanes 22 are evenly installed at the bottom of the cooling chamber 2, and the guide vanes 22 and the conveying rollers 4 are distributed alternately.

[0006] Furthermore, the transverse elongated air inlet 21 and the air guide plate 22 are inclined in the direction of rock wool conveying.

[0007] Furthermore, the conveying roller 4 is connected in series via sprockets and chains, and a motor is connected to the conveying roller 4 for transmission.

[0008] Furthermore, the frame 1 is provided with connecting flanges 11 at both ends for connection to the upstream and downstream conveyors of rock wool processing.

[0009] Furthermore, the cooling chamber 2 is provided with cover plates 23 at both ends to reduce the loss of cold air.

[0010] The beneficial effects of this utility model are: This invention uses conveying rollers to support and transport rock wool. Cold air entering from the transverse elongated air inlet first cools the bottom of the rock wool. The cold air then fills the cooling chamber to form a cooling cavity, which can fully cool and exchange heat, achieving cooling of the sides and top of the rock wool and ensuring the cooling effect. The cooling chamber prevents the cold air from spreading, prolongs the heat exchange time between the cold air and the rock wool, ensures heat exchange efficiency, and reduces energy consumption.

[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0015] This utility model discloses a cooler for rock wool production. The cooler mainly includes a frame 1, a cooling chamber 2, an air distribution chamber 3, conveying rollers 4, an air supply pipe 5, a refrigeration box 6, and a fan 7. The cooling chamber 2 is mounted on the frame 1, and the air distribution chamber 3 is mounted at the bottom of the cooling chamber 2. A horizontal elongated air inlet 21 is provided at the bottom of the cooling chamber 2, and the cooling chamber 2 and the air distribution chamber 3 are connected through the horizontal elongated air inlet 21. Conveying rollers 4 for conveying rock wool are evenly installed at the bottom of the cooling chamber 2. 2. Rock wool inlets and outlets are provided at both ends. Air supply pipes 5 are connected to the bottom of the air distribution chamber 3. Air supply pipes 5 are connected to the refrigeration box 6 and the fan 7 in sequence. Rock wool is supported and conveyed by conveying rollers 4. Cold air entering from the transverse long strip air inlet 21 first cools the bottom of the rock wool. The cold air is filled into the cooling chamber 2 to form a cooling cavity, which can fully cool and exchange heat, and achieve cooling of the sides and top of the rock wool to ensure the cooling effect. The cooling chamber 2 prevents the cold air from spreading, prolongs the heat exchange time between the cold air and the rock wool, ensures heat exchange efficiency, and reduces energy consumption.

[0016] The cooling chamber 2 is equipped with uniformly installed air guide vanes 22 at its bottom, which are distributed alternately with the conveyor rollers 4. The conveyor rollers 4 are connected in series via sprockets and chains, and are driven by a motor. When the front end of each batch of rock wool passes through the cooling chamber 2, the air guide vanes 22 support the rock wool end, and the cold air blown in by the transverse elongated air inlet 21 lifts the rock wool. Combined with the active rotation of the conveyor rollers 4, this effectively prevents the rock wool end from hitting the conveyor rollers 4, reducing the difficulty of threading the rock wool.

[0017] The horizontal elongated air inlet 21 and the air guide plate 22 are inclined in the direction of rock wool conveying.

[0018] The frame 1 is provided with connecting flanges 11 at both ends for connection to the upstream and downstream conveyors of rock wool processing.

[0019] The cooling chamber 2 is equipped with cover plates 23 at both ends to reduce the loss of cold air.

[0020] Work process: As the front end of each batch of rock wool passes through the cooling chamber 2, the rock wool is lifted by the cold air blown in through the horizontal elongated air inlet 21, supported by the guide vane 22. Combined with the active rotation of the conveyor roller 4, this effectively prevents the rock wool end from hitting the conveyor roller 4, reducing the difficulty of threading the rock wool. Supported by the conveyor roller 4, the cold air entering through the horizontal elongated air inlet 21 first cools the bottom of the rock wool. The cold air then fills the cooling chamber 2, forming a cooling cavity that fully cools and exchanges heat, achieving cooling of both sides and the top of the rock wool, ensuring effective cooling. The cooling chamber 2 also prevents the cold air from spreading, extending the heat exchange time between the cold air and the rock wool, ensuring heat exchange efficiency and reducing energy consumption.

[0021] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
