Description

Technical Field

[0001] This utility model relates to the field of diesel engine casting production technology, and in particular to a cooling device for diesel engine castings. Background Technology

[0002] Castings are shaped metal objects obtained through various casting methods. This involves pouring, injecting, suction, or other casting methods into a pre-prepared mold, allowing it to cool, and then processing it through grinding and other methods to obtain an object with a specific shape, size, and performance. Castings have a wide range of applications, including hardware and the entire machinery and electronics industry. For example, diesel engines contain many castings. After casting is formed, it needs to be cooled before subsequent processes can proceed. Current cooling methods mostly involve immersing the casting, but directly immersing the casting can easily cause surface cracking. Natural cooling followed by immersion is inefficient.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0047] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0048] Reference Figures 1 to 5 As shown, a cooling device for diesel engine castings according to an embodiment of the present invention includes: a cooling box 100, a placement basket 200, and a cooling assembly.

[0049] The cooling tank 100 has an inner cavity for storing coolant.

[0050] The placement basket 200 is vertically mounted inside the cooling box 100. The placement basket 200 has a placement groove 201 for placing diesel engine castings. The groove wall of the placement groove 201 is provided with filter holes that penetrate the placement basket 200 for coolant to pass through.

[0051] The cooling assembly includes a cooling fan 300 and a spray device 400. The cooling fan 300 is disposed in the cooling box 100 and blows air toward the placement tank 201, thereby blowing air onto the diesel engine casting placed in the placement tank 201. In addition, the spray device 400 is at least partially disposed in the cooling box 100. The spray device 400 is used to spray coolant onto the air outlet side of the cooling fan 300, that is, the spray device 400 is used to spray coolant between the cooling fan 300 and the placement tank 200, and then the cooling fan 300 blows the coolant sprayed by the spray device 400 toward the diesel engine casting in the placement tank 201 to cool the diesel engine casting.

[0052] In use, the placement basket 200 can be adjusted to a higher position first, and then a certain amount of coolant can be filled into the cooling tank 100. The level of the coolant should be lower than that of the placement basket 200. Then, the diesel engine casting to be cooled can be placed into the placement slot 201 of the placement basket 200. The cooling fan 300 and the spray device 400 can be turned on. The cooling fan 300 blows air towards the diesel engine casting in the placement slot 201, while the spray device 400 sprays coolant towards the air outlet side of the cooling fan 300. The sprayed coolant is driven by the air blown by the cooling fan 300 and sprays onto the diesel engine casting, thereby initially cooling the diesel engine casting. After a certain cooling time, the placement basket 200 can be adjusted to a lower position so that the diesel engine casting is submerged below the level of the coolant in the cooling tank 100. The diesel engine casting is further cooled by immersion. By adopting the above settings, the diesel engine castings can be initially cooled using air cooling and spray cooling, and then further cooled using immersion cooling. This method is highly efficient and does not easily damage the diesel engine castings, making them less prone to cracking. Furthermore, the spray device 400 sprays coolant towards the exhaust side of the cooling fan 300, rather than directly onto the diesel engine castings in the placement tank 201. The coolant sprayed by the spray device 400 can be dispersed by the wind, thus more evenly spraying it onto the diesel engine castings and achieving more uniform cooling.

[0053] It is conceivable that, in order to prevent the spray device 400 from spraying coolant into the cooling fan 300, the direction in which the spray device 400 sprays coolant needs to be set at an angle to the airflow direction of the cooling fan 300. For example, the cooling fan 300 can blow air vertically downwards, while the spray device 400 can spray coolant horizontally.

[0054] It is conceivable that coolant can be water, or a mixture of water, rust inhibitors, lubricants, and corrosion inhibitors.

[0055] It can be assumed that there can be one or more cooling fans 300, and the specific number needs to be determined according to the size of the cooling fan 300 and the size of the diesel engine casting that needs to be cooled.

[0056] Reference Figure 1 As shown, in some embodiments of this utility model, the cooling device for diesel engine castings further includes a circulation assembly 500. The circulation assembly 500 includes a water tank 510 and a circulation pump 520. The water tank 510 stores coolant, and the circulation pump 520 is disposed in the water tank 510 and connected to the cooling box 100 via a circulation pipe 530 to circulate coolant between the cooling box 100 and the water tank 510. Clearly, the cooling box 100 is provided with an inlet pipe and an outlet pipe for connecting to the circulation pipe 530.

[0057] This embodiment sets up a circulation component 500 so that the coolant can circulate between the cooling tank 100 and the water tank 510, thereby enabling the temperature of the diesel engine casting to drop more steadily, effectively preventing cracking or deformation of the diesel engine casting, and providing good cooling effect.

[0058] It is conceivable that the 520 circulating pump can operate continuously to improve cooling efficiency, or it can operate intermittently to reduce energy consumption.

[0059] It is conceivable that a cooling fan (not shown in the figure) could also be installed on the water tank 510 to cool it down.

[0060] Reference Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the cooling box 100 includes a box body 103 and a box cover 104; the top of the box body 103 has an opening, and a basket 200 is placed inside the box body 103; the box cover 104 is horizontally slidable on the top of the box body 103, and the box cover 104 can be opened or closed; a cooling fan 300 is disposed on the box cover 104 and blows air downwards; with the above-described structure, the cooling device for diesel engine castings allows the box cover 104 to be opened when loading or unloading diesel engine castings, and closed when cooling the diesel engine, preventing the hot coolant from splashing out and scalding the operator, thus improving the safety of the device. Furthermore, the cooling fan 300, disposed on the box cover 104 and blowing air downwards, improves the air cooling effect.

[0061] It is conceivable that the cooling fan 300 is located above the placement slot 201 of the placement basket 200 to ensure the air cooling effect.

[0062] It is conceivable that the cooling fan 300 can be powered by an external power source or by an internal power source. When powered by an external power source, a cable management structure needs to be set on the cover 104 to position the power cable of the cooling fan 300 and prevent the power cable of the cooling fan 300 from getting stuck between the cover 104 and the enclosure 103 during the opening and closing of the cover 104.

[0063] Additionally, it should be noted that the enclosure 103 or the cover 104 may be provided with holes or notches for air to be blown out by the cooling fan 300.

[0064] Reference Figure 2 and Figure 3As shown, in some embodiments of this utility model, the front and rear sides of the housing 103 are respectively provided with left and right extending sliding grooves 105, and the front and rear ends of the housing cover 104 are respectively embedded in the corresponding sliding grooves 105 to slide the housing cover 104. The cooling device for diesel engine castings also includes a sliding drive unit 700, which includes a rack 710, a gear 720 and a second motor 730. The rack 710 is disposed on the upper surface of the housing cover 104 and is distributed left and right. The gear 720 meshes with the rack 710 and the central axis of the gear 720 is vertically distributed. The second motor 730 is disposed outside the housing 103 and connected to the gear 720 to drive the gear 720 to rotate around its own axis. Then, through the meshing of the gear 720 and the rack 710, the housing cover 104 is moved left and right, thereby realizing the automatic opening and closing of the housing cover 104.

[0065] It is conceivable that the rack 710 can be fixed to the cover 104 by bolts or other fasteners.

[0066] Reference Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this utility model, the placement basket 200 is vertically slidably installed inside the housing 103 of the cooling box 100. The cooling device for diesel engine castings also includes a lifting drive unit 600, which includes a winding roller 610, a winding rope 620, and a first motor 630. The winding roller 610 is rotatably mounted on the housing 103 of the cooling box 100. One end of the winding rope 620 is wound around the winding roller 610, and the other end is connected to the placement basket 200. The first motor 630 is connected to the winding roller 610 and is used to drive the winding roller 610 to rotate, so as to wind or release the winding rope 620, thereby realizing the lifting and lowering of the placement basket 200. This embodiment achieves the lifting and lowering of the placement basket 200 by adopting a cooperative structure of the winding roller 610, the winding rope 620, and the first motor 630. The structure is compact, occupies little space, and is easy to maintain.

[0067] It is conceivable that two lifting drive units 600 can be provided, located on opposite sides of the placement basket 200 respectively.

[0068] Reference Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the placement basket 200 is provided with a plurality of guide holes 202, and the cooling box 100 is provided with a plurality of vertically extending guide posts 101 inside the box body 103. The guide posts 101 correspond one-to-one with the guide holes 202 and pass through the corresponding guide holes 202, thereby providing guidance for the lifting and lowering of the placement basket 200. The structure is simple and practical.

[0069] Reference Figure 2 and Figure 3As shown, in some embodiments of this utility model, the take-up roller 610 and the first motor 630 are installed on the outside of the housing 103 of the cooling box 100 to reduce their erosion by moisture and improve their service life. Based on this, in order to ensure that the take-up rope 620 can connect to the placement basket 200 and drive the placement basket 200 to rise and fall, the side wall of the housing 103 of the cooling box 100 is provided with an avoidance notch 102 and a deflector pulley 110 is provided on the inside of the avoidance notch 102. The take-up rope 620 passes through the avoidance notch 102 and goes around the deflector pulley 110 to connect downward to the placement basket 200.

[0070] It is understandable that the winding rope 620 located between the redirecting pulley 110 and the winding roller 610 is horizontally distributed, and the winding rope 620 located between the redirecting pulley 110 and the placement basket 200 is vertically distributed.

[0071] It is conceivable that the coolant sprayed by the spray device 400 can come from the outside, or the coolant in the cooling tank 100 can be used directly to reduce costs.

[0072] For example, refer to Figures 1 to 4 As shown, in some embodiments of this utility model, the spraying device 400 includes a nozzle assembly 410, a liquid delivery pipe 420, and a delivery pump 430. The nozzle assembly 410 is disposed inside the housing 103 of the cooling tank 100 and is used to spray coolant onto the exhaust side of the cooling fan 300. The liquid delivery pipe 420 is connected to the nozzle assembly 410, and the delivery pump 430 is connected to the liquid delivery pipe 420. The delivery pump 430 is used to pump the coolant in the cooling tank 100 to the nozzle assembly 410 via the liquid delivery pipe 420.

[0073] Reference Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the nozzle assembly 410 includes a distribution box 411 and multiple spray heads 413. The distribution box 411 is fixed inside the housing 103 of the cooling tank 100 and connected to the liquid delivery pipeline 420 through a pipe joint. The distribution box 411 has a distribution cavity 412, which is connected to the liquid delivery pipeline 420. The spray heads 413 are disposed in the distribution box 411 and are used to spray the coolant in the distribution cavity 412. By providing multiple spray heads 413, the coolant can be sprayed more fully and evenly toward the air outlet side of the cooling fan 300, thereby improving the cooling effect.

[0074] Reference Figure 4 As shown, in some embodiments of this utility model, the outer wall of the diversion box 411 is provided with a connecting pipe 414, which is connected to the diversion cavity 412. The outer wall of the connecting pipe 414 is provided with an external thread, and the spray head 413 is provided with a threaded mounting hole and is threadedly installed on the connecting pipe 414, so that the spray head 413 can be detached and installed, which facilitates the replacement or cleaning of the spray head 413.
