Description

Technical Field

[0001] This invention belongs to the field of conveyors, and specifically relates to a chain conveyor with a cooling pool. Background Technology

[0002] Traditional casting cooling typically involves lifting the casting using a basket or ropes, manually lowering it into a cooling tank, and then removing it after cooling. This completes the cooling process for a single casting. However, this cooling method suffers from poor operational continuity, only allowing for intermittent cooling of single or batch castings. Furthermore, the loading and unloading processes are time-consuming, labor-intensive, and inefficient. Stacking multiple castings together in the cooling tank can also lead to uneven cooling, negatively impacting both the cooling effect and the casting quality.

[0003] On the other hand, traditional cooling pools do not have a dedicated impurity collection structure. Impurities that fall off during the casting cooling process are easily scattered in various areas of the cooling pool, which is not easy to clean. Long-term accumulation of impurities will contaminate the coolant and even block the coolant circulation channels, reducing the cooling effect of the coolant. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a chain conveyor with a cooling pool, which can realize uninterrupted feeding, cooling and discharging, and greatly improve the cooling efficiency and cooling effect of the workpiece.

[0005] The specific technical solution adopted in this invention is as follows:

[0006] A chain conveyor with a cooling pool includes a frame, a motor, a chain, and sprockets. The motor and sprockets are mounted on the frame. The sprockets are driven by the motor to rotate on the frame and mesh with the chain. Chain plates are fixed on the chain. A cooling pool is provided along the conveying path of the chain conveyor. The chain plates include a feeding section, a cooling section, and a lifting section connected in sequence along the conveying path. The cooling section is located in the cooling pool.

[0007] The cooling section is provided with a mesh, the bottom of the cooling pool is provided with a settling trough, and a set of guide ramps are provided in the cooling pool. The settling trough is located below the cooling section, and the inlet of the settling trough is connected to the lower end of the guide ramps. The guide ramps form a slide for impurities in the cooling pool to slide into the settling trough.

[0008] The settling tank is located on one side of the cooling pool. The bottom of the settling tank is inclined. The lower end of the settling tank is provided with an openable slag discharge port. An impurity screening component is also provided inside the settling tank.

[0009] The impurity screening assembly includes a drive shaft with helical blades and an arc-shaped pipe. The arc-shaped pipe is located between the drive shaft and the bottom of the settling tank. Screen holes are provided on the arc-shaped pipe. The axial directions of the drive shaft and the arc-shaped pipe are parallel to the bottom of the settling tank. The conveying direction of the helical blades is inclined upward.

[0010] The cooling pool is also equipped with a set of stirring blades. The rotating shaft of the stirring blades spans across the cooling pool and is located above the cooling section. The length direction of the stirring blades is arranged along the axial direction of the rotating shaft, and the stirring blades are provided with mesh holes.

[0011] The lifting section is provided with a mesh, and a set of spray pipes is arranged horizontally above the lifting section. The spray pipes are equipped with spray heads and are connected to the cooling pool via a circulating water pump. A guide plate connected to the cooling pool is provided below the lifting section.

[0012] An overflow trough is provided between the circulating water pump and the cooling pool. The overflow trough is installed on the side wall of the cooling pool, and an overflow outlet communicating with the overflow trough is provided on the side wall of the cooling pool. A filter screen is also provided on the overflow outlet.

[0013] The beneficial effects of this invention are:

[0014] This invention combines a chain conveyor with a cooling tank to achieve uninterrupted feeding, cooling, and discharging, significantly improving workpiece cooling efficiency.

[0015] The chain plate is equipped with baffles, and the workpiece placement area is formed between adjacent baffles. The baffles can effectively prevent the workpieces from tilting and slipping, reduce the accumulation of workpieces in the cooling pool, and ensure that the workpieces enter and exit the cooling pool with the movement of the chain plate. The workpieces enter the cooling pool in the set order, avoiding multiple workpieces from slipping into the cooling pool at the same time and stacking up, which would cause a sudden change in water temperature and affect the cooling effect.

[0016] The rotation of the helical blades continuously disturbs the coolant in the cooling pool, which helps to equalize the temperature difference of the coolant in the cooling pool.

[0017] The rotation of the shaft causes the two stirring blades on it to alternately enter and exit the coolant. The continuous alternation of entering and exiting the coolant allows the stirring blades, which are cooled in the air, to enter the coolant and exchange heat with it, which helps to reduce the temperature of the coolant and reduce the power consumption of external refrigeration equipment. On the other hand, the disturbance of the coolant by the stirring blades can continuously break the vapor film on the surface of the workpiece, improve the heat exchange efficiency between the workpiece and the coolant, and allow the heat of the workpiece to be transferred to the coolant faster and more fully. The rapid circulation of water caused by the disturbance can also remove this heat in time, further optimizing the temperature control effect of the coolant. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] Specific implementation examples Figure 1 , Figure 2 As shown, this invention relates to a chain conveyor with a cooling pool, comprising a frame 1, a motor 2, a chain, and sprockets. The motor 2 and sprockets are mounted on the frame 1. The sprockets are driven by the motor 2 to rotate on the frame 1 and mesh with the chain for transmission. Chain plates 19 are fixed on the chain. A cooling pool 3 is provided along the conveying path of the chain conveyor. The chain plates 19 include a feeding section 4, a cooling section 5, and a lifting section 6 connected sequentially along the conveying path. Baffles are also provided on the chain plates 19, forming a workpiece placement area between adjacent baffles. The baffles can effectively prevent workpieces from tilting and slipping, reduce the accumulation of workpieces in the cooling pool 3, and ensure that workpieces move in and out of the cooling pool 3 with the chain plates 19, so that the workpieces are placed in accordance with the chain plate 19. Workpieces enter the cooling pool 3 sequentially according to a set order to prevent multiple workpieces from slipping into the cooling pool 3 simultaneously, causing a sudden change in water temperature and affecting the cooling effect. The cooling section 5 is located within the cooling pool 3. The chain can be integral or segmented. When an integral chain is selected, the chain plate 19 divides the chain along the conveying path into a feeding section 4, a cooling section 5, and a lifting section 6. The lifting section 6 is used to remove the workpieces from the cooling pool 3. When a segmented chain is selected, three or two chain segments are set along the conveying path. The feeding section 4, cooling section 5, and lifting section 6 are respectively set on each segment of the separate chain, or two adjacent segments of the feeding section 4, cooling section 5, and lifting section 6 are on the same chain segment, and the remaining segment is set on a separate chain segment. This embodiment uses an integral chain as an example.

[0025] In this invention, the chain conveyor continuously carries the workpiece into the cooling pool 3 and takes it out. By combining the chain conveyor with the cooling pool 3, uninterrupted feeding, cooling and discharging are achieved, which greatly improves the workpiece cooling efficiency.

[0026] The cooling section 5 is equipped with mesh holes. Because an integral chain is used in this embodiment, the chain plates 19, including the feeding section 4 and the lifting section 6, are all equipped with mesh holes. When the workpiece reaches the cooling section 5, it enters the cooling pool 3 and is immersed in the coolant in the cooling pool 3. During the cooling process, impurities such as molding sand and detached metal fragments adhering to the surface of the workpiece can fall into the cooling pool 3 through the mesh holes on the cooling section 5, thus achieving the separation of impurities from the workpiece. Figure 4 As shown, a settling tank 7 is provided at the bottom of the cooling pool 3, and a set of guide ramps 8 are provided inside the cooling pool 3. The settling tank 7 is located below the cooling section 5. The inlet of the settling tank 7 is connected to the lower end of the guide ramps 8. The guide ramps 8 form a slide for impurities in the cooling pool 3 to slide down into the settling tank 7. The impurities slide down automatically along the guide ramps 8 into the settling tank 7, realizing the directional collection of impurities and preventing impurities from scattering in various places at the bottom of the cooling pool 3, which can effectively reduce the difficulty of cleaning impurities.

[0027] The bottom of the settling tank 7 is inclined, and the lower end of the settling tank 7 is provided with an openable slag discharge port 9. The settling tank 7 is also provided with an impurity screening component. The settling tank 7 is located on one side of the cooling pool 3 to avoid interference between the impurity screening component and the chain conveyor.

[0028] like Figure 3 As shown, the impurity screening assembly includes a drive shaft 11 with spiral blades 10 and an arc-shaped pipe 12. The spiral blades 10 have uniformly arranged water passage holes. During the rotation of the spiral blades 10, coolant can fall back along the spiral blades 10 and remain in the cooling pool 3. The arc-shaped pipe 12 is located between the drive shaft 11 and the bottom of the settling tank 7. The arc-shaped pipe 12 has screen holes, and the diameter of the water passage holes on the spiral blades 10 is smaller than the diameter of the screen holes. The axial directions of the drive shaft 11 and the arc-shaped pipe 12 are parallel to the bottom of the settling tank 7. The conveying direction of the spiral blades 10 is inclined upwards. After impurities fall through the mesh on the cooling section 5, they first enter the arc-shaped pipe 12 with the help of the guide ramp 8. The drive shaft 11 drives the spiral blades 10 to rotate. The impurities in the arc-shaped pipe 12 are forced to tilt upwards and disperse. As the impurities move upwards, the small impurities fall through the sieve holes on the arc-shaped pipe 12 to the bottom of the settling tank 7, while the larger impurities are trapped in the arc-shaped pipe 12, which facilitates the subsequent classification and recycling of the impurities. At the same time, the rotation of the spiral blades 10 can continuously disturb the coolant in the cooling pool 3, which helps to balance the temperature difference of the coolant in the cooling pool 3.

[0029] Furthermore, the arc-shaped pipe 12 includes a perforated section 1201 and a non-perforated section 1202 connected to the perforated section 1201. The perforated section 1201 is located above the settling tank 7. The perforated section 1201 and the non-perforated section 1202 are arranged sequentially along the axial direction of the drive shaft 11. The perforated section 1201 is lower than the non-perforated section 1202. A collection trough 20 is provided on the side of the non-perforated section 1202 near the end of the drive shaft 11. Small impurities are pushed down to the bottom of the settling tank 7 by the spiral blades 10, while larger impurities remain in the arc-shaped pipe 12 and continue to move upward at an angle to the non-perforated section 1202 by the spiral blades 10. Finally, they fall into the collection trough 20 on the non-perforated section 1202. The collection trough 20 is located outside the coolant in the cooling pool 3. With the help of the arc-shaped pipe 12, the impurities in the settling tank 7 are difficult to float back to the cooling pool 3. The collection tank 20 is located outside the surface of the coolant in the cooling pool 3, so the impurities in the collection tank 20 cannot return to the cooling pool 3. With the help of this impurity screening component, the impurities in the cooling pool 3 are continuously separated and separated from the coolant, thus realizing the self-cleaning of the coolant and the classification and recycling of impurities.

[0030] The cooling pool 3 is also equipped with a set of stirring blades 13. The rotating shaft 14 of the stirring blades 13 spans across the cooling pool 3 and is located above the cooling section 5. The length direction of the stirring blades 13 is arranged along the axial direction of the rotating shaft 14. The stirring blades 13 are provided with mesh holes. During the upward movement of the stirring blades 13, the coolant falls back into the cooling pool 3 through the mesh holes on the stirring blades 13. Each rotating shaft 14 is equipped with two stirring blades 13, one above the other. The rotation of the rotating shaft 14 causes the two stirring blades 13 to alternately enter and exit the coolant. The continuous alternation of entering and exiting the coolant allows the stirring blades 13, which are cooled in the air, to enter the coolant and exchange heat with the coolant, which helps to reduce the temperature of the coolant and reduce the power consumption of the external refrigeration equipment. On the other hand, the disturbance of the coolant by the stirring blades 13 can continuously break the vapor film on the surface of the workpiece, improve the heat exchange efficiency between the workpiece and the coolant, and allow the heat of the workpiece to be transferred to the coolant faster and more fully. The rapid circulation of water caused by the disturbance can also remove this part of the heat in time, further optimizing the temperature control effect of the coolant.

[0031] The lifting section 6 is equipped with a mesh, and a set of spray pipes 15 are horizontally arranged above the lifting section 6. Spray heads 16 are installed on the spray pipes 15, which are connected to the cooling pool 3 via a circulating water pump 17. A guide plate connected to the cooling pool 3 is located below the lifting section 6. An overflow trough 18 is provided between the circulating water pump 17 and the cooling pool 3, and the overflow trough 18 is installed on the side wall of the cooling pool 3. An overflow outlet communicating with the overflow trough 18 is opened on the side wall of the cooling pool 3, and a filter screen is also installed on the overflow outlet. The coolant in the cooling pool 3 overflows into the overflow trough 18 after being filtered by the filter screen. The circulating water pump 17 draws the coolant from the overflow trough 18 and sends it to the spray pipes 15, where the spray heads 16 further spray and rinse the workpieces on the lifting section 6, further reducing impurities on the workpiece surface and improving the cleanliness of the workpiece surface.

[0032] The overflow outlet ensures that the liquid level in the overflow tank 18 is always consistent with the liquid level in the cooling pool 3, preventing insufficient coolant in the overflow tank 18. The guide plate receives the coolant dripping from the lifting section 6 and guides it into the cooling pool 3, realizing the recycling of coolant.
