Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of cooling equipment, in particular to a cooling device with a cooling structure. BACKGROUND
[0002] In the field of chemical raw material production and processing, cooling devices are the core equipment to ensure the smooth progress of production processes and the quality of products. Currently, most chemical raw material cooling devices mainly rely on cooling cylinders, cooling rods and other components to achieve cooling, but many problems have been exposed in actual operation.
[0003] Firstly, the structural design of the cooling device has defects, resulting in uneven heat exchange between the cooling medium and the chemical raw materials. The raw materials close to the cooling cylinder and cooling rod can quickly dissipate heat and cool down, while the raw materials far from these cooling components cool slowly due to delayed heat transfer, seriously affecting the overall production efficiency and the stability of product quality. Secondly, from the perspective of equipment maintenance, the maintenance operation of the existing cooling device is extremely inconvenient. Once a fault occurs, the production process must be stopped, the material in the equipment must be completely emptied and cleaned before the cooling device can be repaired, which not only greatly increases the downtime and labor cost, but also seriously affects the continuity and timeliness of chemical production. Thirdly, the cooling cylinder, as the main cooling contact surface, is prone to fouling during long-term contact with chemical raw materials due to complex raw material composition and temperature changes.
[0004] Fouling not only reduces the heat transfer performance of the cooling cylinder and weakens the cooling effect, but also exacerbates equipment wear and tear, shortens the service life of the cooling device, and frequent cleaning and maintenance further increases equipment operating costs. With the increasing demand for production efficiency, product quality and equipment reliability in the chemical industry, there is an urgent need to develop a new type of cooling device that can solve the above problems and effectively improve cooling efficiency.

[0068] Further provided, the cooling pipe 13 is provided with a flow regulating valve, the flow regulating valve is connected with the controller, the controller adjusts the opening of the flow regulating valve according to the temperature gradient change of the cooling pipe detected by the temperature sensor 162, controls the flow of the cooling medium, and matches the cooling efficiency with the cooling demand of the raw materials.
[0069] Working principle: when the cooling device works, the chemical raw materials enter the vertical hole 11 from the feed port, are metered by the blades 161 of the quantitative roller 16, and fall into the lower partition bin 30 according to the fixed weight. The chain 32 of the material transfer mechanism 3 drives the sliding of the partition plate 31, so that the partition bin 30 moves circularly in the cooling cavity. The partition plate 31 is scraped when it slides to remove the scale on the inner wall of the cooling inner cylinder 1. When the raw materials move to the upper side of the vertical hole 11 with the partition bin 30, they fall into the lower partition bin 30 through the vertical hole 11, and are turned over to balance the cooling efficiency. In the cooling pipeline, the cooling medium flows into the top of the inlet pipe 131 and flows out from the bottom of the outlet pipe 132, and forms a gradient cooling along the moving direction of the raw materials. The pressure trigger device 17 adjusts the pressure of the top sheet 173 through the electromagnetic device 176 to control the rotation frequency of the quantitative roller 16, so as to ensure that the quantitative roller 16 rotates 90 degrees and distributes a fixed weight of raw materials each time. The temperature sensor 162 rotates with the quantitative roller 16 to detect the temperature of the inlet and outlet of the cooling pipe 13 and the raw materials, and the controller adjusts the flow regulating valve according to the temperature data to match the flow of the cooling medium with the cooling demand of the raw materials. The maintenance opening 23 on one side of the empty partition bin 30 can be maintained without stopping, the rubber strip 33 cooperates with the sealing plate 24 to seal the cooling cavity, the anti-sticking coating of the partition plate 31 avoids the residue of the raw materials, and the efficient operation of the device is ensured.
[0070] In summary, the chemical raw material cooling device with the novel cooling structure, by setting the cooling outer cylinder 2 outside the cooling inner cylinder 1, and setting the material transfer mechanism 3 containing multiple partition plates 31 in the cooling cavity between the two, the cooling cavity is divided into multiple partition bins 30 to accommodate the chemical raw materials. On the one hand, the multiple partition bins 30 can orderly transfer the chemical raw materials in the cooling cavity, increase the contact area and time of the raw materials and the cooling inner cylinder 1, and thus improve the cooling effect; on the other hand, the partition plate 31 can scrape off the scale to prevent the formation of a heat insulation layer on the surface of the cooling inner cylinder 1 due to the scale, ensure efficient heat exchange between the cooling medium and the raw materials, and avoid the decrease of the cooling efficiency caused by the scale. In addition, the cooling cavities on the upper and lower sides of the cooling outer cylinder 2 are connected through the vertical hole 11, the raw materials are turned over by falling through the vertical hole 11, the cooling efficiency inside and outside the partition bin 30 is avoided, the partition bin 30 on one side of the vertical hole 11 is empty, the maintenance through the maintenance opening 23 on the cooling inner cylinder 1 is facilitated in the state of having raw materials, the downtime for maintenance is reduced, and the production efficiency is improved.
[0071] By setting the quantitative roller 16 in the vertical hole 11, and setting the pressure trigger device 17 at the rotating connection between the quantitative roller 16 and the inner wall of the vertical hole 11, the rotation frequency of the quantitative roller 16 is limited, so that it rotates when the weight of the raw material on the blade 161 exceeds the expected value and the vertical hole 11 is directly opposite the compartment 30 below, and each rotation of 90 degrees distributes a fixed weight of raw material to the corresponding compartment 30, achieving the effect of precise control of the raw material feeding amount and uniform cooling. The quantitative feeding can ensure that the amount of raw material in each compartment 30 is consistent, avoiding uneven cooling effects caused by different raw material accumulation thicknesses. At the same time, the quantitative roller 16 turns the raw material, improving the turning effect of the vertical hole 11 on the raw material.
[0072] By setting the cooling pipe 13 containing the liquid inlet pipe 131 and the liquid outlet pipe 132, and the starting point of the liquid inlet pipe 131 being located at the top of the cooling inner cylinder 1, the ending point of the liquid outlet pipe 132 being located at the bottom of the cooling inner cylinder 1, and the cooling pipe 13 being distributed along the direction of the raw material movement, and setting the temperature sensor 162 on one blade 161 of the quantitative roller 16, the gradient change of the temperature of the cooling pipe 13 and the temperature of the raw material after each round of cooling are detected, achieving the effect of optimizing the cooling process and ensuring the cooling quality. The layout of the cooling pipe 13 gradually enhances the cooling efficiency of the raw material when it moves in the cooling cavity, meeting the cooling demand of the raw material and avoiding energy waste. The temperature sensor 162 rotates with the quantitative roller 16, respectively detecting the temperature on the side close to the liquid inlet pipe 131 and the liquid outlet pipe 132 and the temperature of the raw material, which can real-time feedback the temperature information in the cooling process, facilitating the staff to adjust the cooling parameters in time according to the data, ensuring that the chemical raw material achieves the ideal cooling effect, and improving the controllability of product quality and production process.
