Description

Technical Field

[0001] The utility model relates to the cooling field, and more specifically, it relates to a novel boiling cooling bed. Background Art

[0002] When sand casting is carried out, it is often necessary to recycle and reuse the old sand; in the process of recycling the old sand, the high-temperature old sand needs to be quickly restored to a certain temperature. The boiling cooling bed is a device that cools the high-temperature old sand. Generally, the boiling cooling bed uses wind power to cool the molding sand.

[0003] After casting, the molding sand is in a state of being bonded together to form hard sand blocks of different sizes. The boiling cooling bed under the existing technology cannot crush the molding sand. In order to prevent the sand blocks from being too large to be cooled, it is necessary to crush the molding sand with a crushing device before cooling, and then send it to the boiling cooling bed for cooling. This reduces the casting efficiency to a certain extent and affects the output.

[0004] Based on the above, the purpose of the present invention is to provide a novel boiling cooling bed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a new type of boiling cooling bed. The utility model arranges cooling rollers in the box for preliminary cooling and crushing of the molding sand, then arranges sprinkler nozzles for further cooling of the molding sand, and finally uses fans to air dry and further cool the sand, thereby improving cooling efficiency and production efficiency.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a new type of boiling cooling bed, including a box body, the inner cavity of the box body is divided into a crushing chamber, a cooling chamber and a drying chamber, the crushing chamber and the drying chamber are respectively provided with a feed port and a discharge port, a conveyor is provided in the box body, and the moving path of the conveyor passes through the crushing chamber, the cooling chamber and the drying chamber in sequence, a pair of cooling rollers are rotatably connected to the side of the crushing chamber close to the feed port, the cooling rollers are provided with crushing teeth, a driving mechanism for driving the two cooling rollers to rotate relative to each other is provided on the box body, a sprinkler nozzle is provided in the cooling chamber, and a plurality of fans are provided in the drying chamber.

[0007] By adopting the above technical scheme, when it is necessary to cool the molding sand, the sprinkler nozzle 1 and the two cooling rollers are connected to the external water supply device, and then the two cooling rollers are driven to rotate relative to each other through the driving mechanism, and then the conveyor 1 is started to operate, and the molding sand can be poured into the box through the inlet, and the two relatively rotating cooling rollers will break the large pieces of molding sand into small pieces through the crushing teeth. During the crushing process, the cooling rollers will also perform preliminary cooling on the molding sand, and then send it to the discharge port through the conveyor 1. In this process, the coolant sprayed by the sprinkler nozzle 1 will cool the molding sand again, and then the fan will air-dry and further cool the molding sand. The cooling efficiency is high, and there is no need to crush the molding sand model in advance, thereby improving production efficiency.

[0008] The utility model is further configured as follows: a water reservoir and a water pump are arranged on the box body, and a water inlet and a water outlet of the water pump are respectively connected to the water reservoir and the sprinkler nozzle.

[0009] The utility model is further configured as follows: the water reservoir is divided into a warm water chamber and a cold water chamber, a sprinkler nozzle two is arranged in the crushing chamber, a cooling pipe one and a cooling pipe two are arranged in the drying chamber, a water pump two is arranged on the box body, a water inlet and a water outlet of the water pump two are respectively connected to the warm water chamber and the cooling pipe one, the other end of the cooling pipe one is connected to the water inlets of two cooling rollers, the water outlet of the cooling roller is connected to the sprinkler nozzle two, the water inlet and the water outlet of the water pump one are respectively connected to the cold water chamber and the cooling pipe two, and the other end of the cooling pipe two is connected to the sprinkler nozzle one.

[0012] The utility model is further configured as follows: a second conveyor is arranged on the box body, one end of the second conveyor is in contact with the ground, and the other end of the second conveyor extends to the feed inlet.

[0013] In summary, the utility model has the following beneficial effects:

[0014] The utility model provides a cooling roller for preliminarily cooling and crushing the molding sand in a box body, and then provides a cooling pipe 1, a cooling pipe 2, a warm water cavity, a cold water cavity, and a water pump 1 and a water pump 2 that drive the coolant to flow among the cooling pipe 1, the cooling pipe 2, the warm water cavity, the cold water cavity, the cooling roller, the sprinkler nozzle 1 and the sprinkler nozzle 2.

[0020] The utility model is described in detail below in conjunction with the accompanying drawings.

[0021] A new type of boiling cooling bed, such as Figure 1 As shown, it includes a box body 1, the inner cavity of the box body 1 is divided into a crushing chamber 2, a cooling chamber 3 and a drying chamber 4, the crushing chamber 2 and the drying chamber 4 are respectively provided with a feed port 5 and a discharge port 6, a conveyor 7 is installed in the box body 1, and the moving path of the conveyor 7 passes through the crushing chamber 2, the cooling chamber 3 and the drying chamber 4 in sequence, a pair of cooling rollers 8 are rotatably connected to the side of the crushing chamber 2 close to the feed port 5, and a plurality of crushing teeth 9 are fixedly connected to the cooling roller 8, a driving mechanism for driving the two cooling rollers 8 to rotate relative to each other is provided on the box body 1, and the driving mechanism may include a motor and a driving gear fixedly connected to the output shaft of the motor, and a gear ring meshing with the driving gear is fixedly connected to the cooling roller (because driving the cooling roller to rotate is a mature existing technology, the corresponding structure is not drawn in the figure), a sprinkler head is installed in the cooling chamber 3, and a plurality of fans 10 are installed in the drying chamber 4.

[0022] A water reservoir 11 and a water pump 1 (not shown in the figure) are fixedly connected to the box body 1, and a filter screen 17 is detachably connected to the water reservoir 11. The water reservoir 11 is divided into a warm water chamber 12 and a cold water chamber 13. A sprinkler nozzle 2 14 is installed in the crushing chamber, and a cooling pipe 15 and a cooling pipe 2 16 are installed in the drying chamber 4. The cooling pipe 15 and the cooling pipe 2 16 are both arranged in a circuitous shape. A water pump 2 (not shown in the figure) is installed on the box body 1. The water inlet and water outlet of the water pump 2 are respectively connected to the warm water chamber 12 and the cooling pipe 1 15, and the other end of the cooling pipe 1 15 is connected to the water inlet of the two cooling rollers 8, and the water outlet of the cooling roller 8 is connected to the sprinkler nozzle 2 14. The water inlet and water outlet of the water pump 1 are respectively connected to the cold water chamber 13 and the cooling pipe 2 16, and the other end of the cooling pipe 2 16 is connected to the sprinkler nozzle 1.

[0023] A conveyor 18 is installed on the box body 1, one end of the conveyor 18 is in contact with the ground, and the other end of the conveyor 18 extends to the feed inlet.

[0024] Working principle: When the molding sand needs to be cooled, inject a proper amount of coolant into the warm water chamber 12 and the cold water chamber 13, then start the conveyor 1 7, conveyor 2 18, water pump 1 and water pump 2, and then drive the two cooling rollers 8 to rotate relative to each other. Water pump 2 will drive the coolant in the warm water chamber 12 to pass through the cooling pipe 1 15 and the cooling roller 8 in turn and then be sprayed out through the sprinkler nozzle 2 14. Water pump 1 will drive the coolant in the cold water chamber 13 to pass through the cooling pipe 2 16 and then be sprayed out through the sprinkler nozzle 19.

[0025] At this time, the user places the molding sand that needs to be cooled on the conveyor 18, and the conveyor 18 will transport the molding sand to the feed port 5. The molding sand then passes through the feed port 5 into the box 1. At this time, the two relatively rotating cooling rollers 8 will break the large pieces of molding sand into small pieces through the crushing teeth 9. In the process of crushing, the cooling rollers 8 exchange heat with the molding sand through the coolant flowing inside, thereby achieving a preliminary cooling effect. The coolant with a higher temperature after the heat exchange is further cooled by the sprinkler nozzle 14 to prevent the molding sand particles from breaking or deforming due to excessive cooling.

[0026] Then the molding sand is sent to the discharge port 6 through the conveyor 7. In this process, when the molding sand passes through the cooling chamber 3, the coolant sprayed by the sprinkler nozzle will cool the molding sand again, and the coolant will fall back to the warm water chamber 12 and the cold water chamber 13 for recycling, and the filter 17 will filter the molding sand to prevent the molding sand from clogging the water pump or water pipe. The molding sand then passes through the drying chamber. In this process, the fan 10 will create an airflow moving in the direction of the molding sand. The airflow will first pass through the cooling tube 2 16 and the cooling tube 1 15, and the airflow will exchange heat with the cooling tube 2 16 and the cooling tube 1 15, thereby cooling the coolant inside, ensuring the subsequent cooling effect, and the temperature of the airflow after the heat exchange will increase to form hot air, and the hot air will dry the molding sand. With this arrangement, the heat energy on the molding sand is recycled, which improves the cooling efficiency of the boiling cooling bed, and there is no need to crush the molding sand model in advance, thereby improving production efficiency.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
