Description

Technical Field

[0001] This utility model relates to the field of clay sand treatment technology, specifically a drum sand cooling machine for clay sand treatment. Background Technology

[0002] A drum sand cooler for clay sand treatment is a device specifically designed for processing clay sand (also known as molding sand) in the foundry industry. A drum sand cooler typically consists of a long, slightly inclined rotating drum. When the machine is running, hot sand is fed into the higher end of the drum and slowly moves towards the lower end as the drum rotates. During this process, the sand impacts the inner wall of the drum or internal lifting plates, thus achieving the purpose of sand removal and cooling. Air can pass through the drum to help cool the sand, and some designs may also incorporate a water spray device to assist the cooling process.

[0003] Patent CN216176552U discloses a drum-type sand cooling machine for clay sand processing. It includes an inclined plate with a support block fixedly installed on its top. A drum slidably connected to the support block is positioned above it. Two fixed plates are fixedly installed on one side of the drum on the top of the inclined plate, and a drive mechanism connected to the drum is mounted on the fixed plates. Hollow spiral blades are installed inside the drum, and spiral cooling water pipes are installed within the hollow spiral blades. A first cooling mechanism is located on the other side of the drum on the top of the inclined plate. This machine not only provides circulating cooling for castings and hot sand added to the drum, resulting in good cooling effect and improved cooling efficiency, but also prevents dust from scattering during molding sand screening and harming the health of workers, ensuring the cooling effect of the molding sand screened into the guide hopper. It is highly practical.

[0004] However, the above-mentioned roller sand cooling machine still has the following problems: when the roller guides the clay sand to cool by rotating and cooperating with the inner spiral blades, if the roller tilt is insufficient, a large amount of clay sand may stick to the spiral blades and the inner side of the roller, causing the clay sand to accumulate inside the roller, which is not conducive to the stable operation of the roller sand cooling. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drum sand cooling machine for clay sand treatment, thereby improving the applicability of the drum sand cooling machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drum sand cooling machine for clay sand treatment, comprising an inclined plate mounted on a base plate and a cooling drum mounted on the inclined plate, a rotating component connected to the bottom of the inclined plate near the discharge end of the cooling drum, the other end of the rotating component connected to the base plate, a lifting component connected to the bottom of the inclined plate away from the rotating component, the other end of the lifting component connected to the base plate.

[0007] Furthermore, a reinforcing plate is fixedly connected to the upper surface of the base plate near the lifting assembly, with the top of the reinforcing plate abutting against the bottom of the inclined plate.

[0008] Furthermore, the rotating assembly includes a support plate and two rotating blocks. The support plate is fixedly connected to the upper surface of the bottom plate near the discharge end of the cooling drum. The two rotating blocks are rotatably connected to the two ends of the top of the support plate via rotating shafts. Both rotating blocks are fixedly connected to the bottom of the inclined plate.

[0009] Furthermore, there are two lifting components, and both lifting components are located between the base plate and the inclined plate.

[0010] Furthermore, the lifting assembly includes two tilting parts of the lifting cylinder, which are respectively connected to both ends of the lifting cylinder and respectively connected to the side of the base plate and the inclined plate adjacent to each other.

[0011] Furthermore, the flipping component includes a flipping block and two fixed blocks. The flipping block is fixedly connected to the end of the lifting cylinder, and the two fixed blocks are located on both sides of the flipping block. The flipping block is fixedly connected to the two fixed blocks through a rotating shaft, and the side of the two fixed blocks away from the lifting cylinder is fixedly connected to the base plate or inclined plate.

[0012] Furthermore, the side of the lifting cylinder furthest from the rotating assembly abuts against the reinforcing plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This type of drum sand cooling machine for clay sand treatment can change the inclination of the drum by cooperating with the lifting and rotating components. This allows the clay sand inside the drum to be discharged more smoothly, reducing the possible accumulation of clay sand inside the drum, improving the sand discharge stability of the drum cooling machine, and ensuring the smooth operation of drum cooling and sand discharge.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 A clay sand treatment roller cooling machine includes an inclined plate 2 installed on a base plate 1 and a cooling roller 3 installed on the inclined plate 2. A rotating component 4 is connected to the bottom of the inclined plate 2 near the discharge end of the cooling roller 3. The other end of the rotating component 4 is connected to the base plate 1. A lifting component 5 is connected to the bottom of the inclined plate 2 away from the rotating component 4. The other end of the lifting component 5 is connected to the base plate 1.

[0022] like Figures 1 to 4 As shown, the drum sand cooling machine for clay sand treatment in this utility model is structurally similar to existing drum sand cooling machines for clay sand treatment, such as the drum sand cooling machine for clay sand treatment disclosed in patent publication number CN216176552U. The main improvement of this utility model is to reduce the accumulation of clay sand in the drum and improve the smoothness of the flow of clay sand in the drum. Figures 1 to 4 As shown, when the clay sand treatment drum cooling machine of this utility model is in use, if it is found that the clay sand is stuck or accumulated in the cooling drum 3, the height of one end of the inclined plate 2 on the base plate 1 can be raised by the lifting component 5, and the tilt of the inclined plate 2 on the base plate 1 can be increased by the rotating component 4 at the other end. This allows the clay sand in the cooling drum 3 to descend more smoothly and eventually be discharged, completing the cooling and sand removal operation. After the sand removal operation is completed, the higher end of the inclined plate 2 can be lowered by the lifting component 5 to reduce the height, thereby facilitating the cleaning of the inside of the cooling drum 3 and improving the applicability of the drum cooling machine.

[0023] like Figures 1 to 4 As shown, a reinforcing plate 6 is fixedly connected to the upper surface of the base plate 1 near the lifting assembly 5, and the top of the reinforcing plate 6 abuts against the bottom of the inclined plate 2. When the higher end of the inclined plate 2 is lowered by the lifting assembly 5 and the inclined plate 2 is parallel to the base plate 1, the end of the inclined plate 2 abuts against the reinforcing plate 6. The reinforcing plate 6 can be used to prevent the inclined plate 2 from falling further, thereby improving the stability of the inclined plate 2 in a horizontal state and improving the stability and safety of the cleaning operation of the cooling roller 3.

[0024] like Figures 1 to 4 As shown, the rotating assembly 4 includes a support plate 41 and two rotating blocks 42. The support plate 41 is fixedly connected to the upper surface of the base plate 1 near the discharge end of the cooling drum 3. The two rotating blocks 42 are rotatably connected to the two ends of the top of the support plate 41 via rotating shafts. Both rotating blocks 42 are fixedly connected to the bottom of the inclined plate 2. When the inclined plate 2 changes its tilt angle via the lifting assembly 5, the other end of the inclined plate 2 is flipped on the support plate 41 via the two rotating blocks 42 and rotating shafts, thus completing the change of the tilt angle of the inclined plate 2.

[0025] like Figures 1 to 4 As shown, there are two lifting components 5, both located between the base plate 1 and the inclined plate 2. By installing two lifting components 5 on the bottom of the inclined plate 2, the two synchronously operating lifting components 5 can ensure uniform force distribution on the lifting end of the inclined plate 2, thus improving the stability of the lifting operation.

[0026] like Figures 1 to 4 As shown, the lifting assembly 5 includes two tilting parts 8 of the lifting cylinder 7. The two tilting parts 8 are connected to both ends of the lifting cylinder 7, and are respectively connected to the adjacent side of the base plate 1 and the inclined plate 2. During the extension and retraction process, the lifting cylinder 7 is connected to the inclined plate 2 and the base plate 1 through the upper and lower tilting parts 8, thereby ensuring that the lifting cylinder 7 can tilt along with the inclined plate 2 when it tilts and rises.

[0027] like Figures 1 to 4 As shown, the tilting component 8 includes a tilting block 81 and two fixed blocks 82. The tilting block 81 is fixedly connected to the end of the lifting cylinder 7. The two fixed blocks 82 are located on both sides of the tilting block 81, and the tilting block 81 is fixedly connected to the two fixed blocks 82 via a rotating shaft. The side of the two fixed blocks 82 away from the lifting cylinder 7 is fixedly connected to the base plate 1 or the inclined plate 2. The end of the lifting cylinder 7 rotates between the two fixed blocks 82 via the tilting block 81, thereby realizing the tilting movement of the lifting operation.

[0028] like Figures 1 to 4 As shown, the side of the lifting cylinder 7 away from the rotating component 4 abuts against the reinforcing plate 6. When the inclined plate 2 abuts against the top of the reinforcing plate 6, the side wall of the lifting cylinder 7 abuts against the side of the reinforcing plate 6, which can prevent the lifting cylinder 7 from tilting to the side away from the rotating component 4, ensuring that the inclined plate 2 can smoothly flip and tilt upwards when the lifting cylinder 7 is lifted, and improving the stability of the inclined plate 2 angle change operation.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
