Description

Technical Field

[0001] This utility model relates to the technical field of molding sand cooling equipment, and in particular to a water-cooled cooling device. Background Technology

[0002] Quartz sand is commonly used for molding in casting processes, and to conserve resources, the molding sand must be recycled. Since the molding sand absorbs a significant amount of heat from the casting, its temperature must be lowered to enable continuous production. Existing molding sand cooling equipment is the fluidized bed cooler. However, fluidized bed coolers have low cooling efficiency, resulting in incomplete cooling of the molding sand and impacting the casting process.

[0003] To this end, the utility model authorized by announcement number CN214557151U provides a water-cooled cooling bed, including a boiling plate installed inside the hollow bed body and a feed hopper, an air outlet, and a discharge outlet connected to the inside and outside of the hollow bed body. The hollow space of the hollow bed body is provided with parallel water-cooling pipelines. The water inlet end of the water-cooling pipelines is connected to a cold water pool through a water pump, and a condenser is provided between the drain end and the cold water pool. The equipment has a simple structure. By installing parallel water-cooling pipelines in the hollow space of the hollow bed body, large-area rapid water cooling can be achieved, reducing the failure rate, facilitating quick replacement and maintenance, thereby improving production efficiency, avoiding resource waste, and reducing costs.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems: when the patented technology cools the molding sand, it cannot control the amount of molding sand fed, and when the amount of molding sand is large, it cannot effectively reduce its temperature; in addition, the contact area between the molding sand and the cooling water pipe is not large, and the cooling efficiency needs to be improved. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by developing a water-cooled cooling device. This device can limit the amount of molding sand fed into the machine, achieving effective cooling of the molding sand with high cooling efficiency and improving production efficiency.

[0006] The technical solution to the technical problem solved by this utility model is as follows: The embodiment of this utility model provides a water-cooled cooling device for cooling molding sand, including a cooling jacket, a spiral rod, a motor, a water pump, and a cooler. The cooling jacket is fixed and includes an outer sleeve and an inner sleeve. A spiral guide plate is provided on the surface of the spiral rod. The spiral rod passes through both ends of the inner sleeve. The output shaft of the motor is connected to the spiral rod. One end of the inner sleeve is provided with an upward-facing inlet, and the other end of the inner sleeve is provided with a downward-facing outlet. The outer sleeve wraps around the inner sleeve. A drain outlet is provided at the end of the outer sleeve near the inlet, and a water inlet is provided at the end of the outer sleeve near the outlet. The drain outlet is connected to the water pump and the cooler in sequence, and then connected to the water inlet.

[0007] As an optimization, the water-cooled cooling device also includes a lower support and an upper support. The two ends of the cooling jacket are fixed on the lower support and the upper support, respectively. The two ends of the spiral rod are mounted on the lower support and the upper support through bearing seats, respectively. The motor is mounted on the lower support or the upper support. The lower support is located at the end near the feed inlet, and the upper support is located at the end near the discharge outlet.

[0008] As an optimization, the bottom of the lower support and the upper support are also provided with foot cups, the upper end of which is a screw, and the bottom of the lower support and the upper support are provided with threaded holes corresponding to the foot cup screws; the top of the lower support and the upper support are both provided with swing plates, and bearing seats are installed on the top of the swing plates, and the swing plates are hinged to the lower support and the upper support.

[0009] As an optimization, the water-cooled cooling device also includes a passive wheel, a belt, and a driving wheel. The passive wheel is installed at the end of the screw rod, the driving wheel is installed on the output shaft of the motor, and the belt connects the passive wheel and the driving wheel.

[0010] As an optimization, a receiving trough is also provided below the discharge port, and the receiving trough is perpendicular to the cooling jacket.

[0011] As an optimization, a spiral water guide plate is also provided between the outer sleeve and the inner sleeve, with the top and bottom surfaces of the water guide plate respectively fitting against the inner cavity of the outer sleeve and the outer surface of the inner sleeve.

[0012] As an optimization, the drain outlet and water inlet are both located at intervals on the water guide plate.

[0013] As an optimization, the cooler is composed of multiple zigzag hollow tubes and is immersed in a cold water pool.

[0014] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0015] 1. By setting a spiral rod that runs through both ends of the inner sleeve, the motor can control the speed of the spiral rod, thereby limiting the feed rate of molding sand and achieving effective cooling of the molding sand. The cooling efficiency is high, thus improving production efficiency. The flow direction of the molding sand is opposite to that of the cold water, realizing the interaction of hot and cold water and improving cooling efficiency.

[0016] 2. By installing foot cups at the bottom of the lower and upper supports, the height of the lower and upper supports can be adjusted by rotating the foot cups, thereby adjusting the inclination of the cooling jacket and the auger, and further controlling the conveying speed of the molding sand.

[0017] 3. By setting up a material collection trough perpendicular to the cooling jacket, the discharge material can be diverted and collected in narrow spaces, saving space.

[0018] 4. By installing a spiral water guide plate between the outer and inner sleeves, the flow path of cold water is restricted and lengthened, thereby improving cooling efficiency. Attached Figure Description

Detailed Implementation

[0031] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0032] Figures 1 to 11As one embodiment of this utility model, such as Figure 1 As shown, a water-cooled cooling device for cooling molding sand includes a cooling jacket 1, a screw rod 2, a motor 8, a water pump 20, and a cooler 21. The cooling jacket 1 is fixed. Figure 5 As shown, the cooling jacket 1 includes an outer sleeve 11 and an inner sleeve 12. A spiral guide plate is provided on the surface of the spiral rod 2, which passes through both ends of the inner sleeve 12. The output shaft of the motor 8 is connected to the spiral rod 2. One end of the inner sleeve 12 has an upward-facing inlet 15, and the other end has a downward-facing outlet 16. The outer sleeve 11 wraps around the inner sleeve 12. A drain outlet 13 is provided at the end of the outer sleeve 11 near the inlet 15, and a water inlet 14 is provided at the end of the outer sleeve 11 near the outlet 16. Figure 1 As shown, the drain outlet 13 is connected in sequence to the water pump 20, the cooler 21, and then to the water inlet 14. The cooler 21 is composed of multiple zigzag hollow tubes and is immersed in a cold water pool. The water-cooled cooling device also includes a lower support 3 and an upper support 4. The two ends of the cooling sleeve 1 are fixed to the lower support 3 and the upper support 4, respectively. The two ends of the spiral rod 2 are mounted on the lower support 3 and the upper support 4, respectively, through bearing seats 23. The motor 8 is mounted on the lower support 3 or the upper support 4. The lower support 3 is located at the end near the feed inlet 15, and the upper support 4 is located at the end near the discharge outlet 16.

[0033] The bottom of the lower bracket 3 and the upper bracket 4 are also provided with feet, the upper end of which is a screw, and the bottom of the lower bracket 3 and the upper bracket 4 are provided with threaded holes corresponding to the screws of the feet; for example Figure 6 As shown, both the lower support 3 and the upper support 4 are equipped with swing plates 22 at their tops, and bearing seats 23 are installed on the tops of the swing plates 22. The swing plates 22 are hinged to the lower support 3 and the upper support 4. By setting foot cups at the bottom of the lower support 3 and the upper support 4, the height of the lower support 3 and the upper support 4 can be adjusted by rotating the foot cups, thereby adjusting the inclination of the cooling jacket 1 and the spiral rod 2, and further controlling the conveying speed of the molding sand.

[0034] like Figure 2 As shown, the water-cooled cooling device also includes a driven wheel 5, a belt 6, and a driving wheel 7. The driven wheel 5 is installed at the end of the screw rod 2, and the driving wheel 7 is installed on the output shaft of the motor 8. The belt 6 connects the driven wheel 5 and the driving wheel 7. A receiving trough 9 is also provided below the discharge port 16, and the receiving trough 9 is perpendicular to the cooling sleeve 1. By setting the receiving trough 9 perpendicular to the cooling sleeve 1, the discharge can be redirected and collected in narrow spaces, saving space.

[0035] like Figure 10 , Figure 11As shown, a spiral water guide plate 17 is also provided between the outer sleeve 11 and the inner sleeve 12. The top and bottom surfaces of the water guide plate 17 are respectively in contact with the inner cavity of the outer sleeve 11 and the outer surface of the inner sleeve 12. By providing the spiral water guide plate 17 between the outer sleeve 11 and the inner sleeve 12, the flow path of the cold water is restricted and lengthened, thereby improving the cooling efficiency. The drain outlet 13 and the inlet 14 are both located at intervals of the water guide plate 17.

[0036] By setting a spiral rod 2 that runs through both ends of the inner sleeve 12, the motor 8 can control the rotation speed of the spiral rod 2, thereby limiting the feed rate of molding sand and achieving effective cooling of the molding sand. This results in high cooling efficiency and improved production efficiency. The flow direction of the molding sand is opposite to that of the cold water, achieving thermal interaction and further improving cooling efficiency. Specifically, when the temperature of the molding sand exiting the outlet 16 is higher than required, the rotation speed of the motor 8 is reduced; conversely, when the temperature of the molding sand exiting the outlet 16 is significantly lower than required, the rotation speed of the motor 8 can be increased.

[0037] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
