Description

Technical Field

[0001] This utility model relates to the field of annular cooler technology, specifically to a cyclic energy-saving annular cooler drive control device. Background Technology

[0002] In the steel, non-ferrous metallurgical and other metallurgical industries, the ring cooler is the core equipment for cooling sintered ore and pellets. Its operation directly affects the continuity of the entire production process, product quality and the economic benefits of enterprises.

[0003] A related technology (publication number: CN117213259A) discloses a drive control device for an annular cooler. The disclosed technical solution is as follows: a laser displacement sensor is installed on the bearing housing to detect the distance L between the annular cooler and the sensor itself. The measured value is transmitted to the controller. The controller calculates that when the distance L is within a set reasonable range, it does not send a control signal to drive the hydraulic cylinder to move. When the L value exceeds the set range, it indicates that the annular cooler is deformed. At this time, based on the sign of the L value exceeding the normal value, the distance that the hydraulic rod needs to extend or retract is calculated. Based on this, the controller sends a control signal to drive the hydraulic rod to extend or retract, thereby completing the radial adjustment of the gear.

[0004] The aforementioned disclosed technical solutions reveal the following problems: Most annular cooler drive control devices employ a constant-speed drive mode. In this mode, regardless of the amount of material inside the annular cooler, its temperature, or changes in cooling demand, the drive motor maintains a constant speed. During the continuous output of cooling air from the annular cooler, when cooling air is not needed in certain areas, the continued output of cooling air increases energy consumption. To address this, we propose a novel circulating energy-saving annular cooler drive control device.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the energy-saving problem of the existing circular air cooler, this utility model provides a circulating energy-saving circular air cooler drive control device, which adopts a zoned control structure combined with a cold air circulation structure to achieve energy-saving effects. Its specific technical solution is as follows:

[0007] A circulating energy-saving ring refrigeration unit drive control device includes a ring-shaped cold compartment. A support is embedded at the center of the ring-shaped cold compartment. Partitions extending into the ring-shaped cold compartment are circumferentially slidably arranged on the support. A partition control component for independently controlling the opening and closing of each partition is provided in the inner cavity of the support. A refrigeration unit is fixedly connected to the top of the support. Output pipes extending into each cold compartment are evenly arranged at the output end of the refrigeration unit.

[0008] In the above technical solution, the partition plate divides the annular cold compartment into various cold zones, each of which is equipped with a temperature sensor, and each output pipe is equipped with a solenoid valve connected to each of the temperature sensors.

[0009] The return air port of the refrigeration unit is provided with a manifold, and the outer wall of the manifold is uniformly provided with return pipes extending into each cold zone of the annular cold compartment. Each return pipe is provided with a solenoid valve connected to each of the temperature sensors.

[0010] The outer wall of the reflux pipe is fitted with a sleeve that is fixed to the annular cold compartment.

[0011] The partition control assembly includes an electric push rod that is uniformly fixed to the support in a circumferential direction. The movable end of the electric push rod is fixed to a pushing member. The partition plate extends to one side of the inner cavity of the support and is provided with a force-bearing member. The side wall of the force-bearing member is provided with an inclined surface that contacts the pushing member, and the force-bearing member is connected to the inner wall of the support through an elastic member.

[0012] The elastic member includes a connecting frame fixed between the force-bearing member and the partition plate, and the connecting frame is connected to the inner wall of the support through an elastic member.

[0013] The bottom of the annular cold storage is uniformly and fixedly equipped with docking seats.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the driving control device for the circulating energy-saving ring cooler:

[0015] 1. During the refrigeration process, in areas without goods, the corresponding independent zone control components isolate these areas and shut off the corresponding output pipes, concentrating the cold air towards the areas with goods. Each independent zone partition is controlled according to the location of the goods, thereby reducing the energy consumption of the refrigeration unit and preventing the cold air from being discharged into areas without goods. By inputting the cooling capacity into areas with concentrated goods, energy-saving effects are achieved, avoiding excessive cooling output.

[0016] Second, a temperature sensor monitors the temperature in each cooling zone in real time. When the temperature sensor detects that the temperature is within the cooling range, the solenoid valve closes the output pipe of the corresponding zone. When the temperature sensor detects that the temperature in the zone is higher than the preset temperature value, the solenoid valve opens and continues to supply cooling air. By automatically controlling the cooling air input, energy-saving effects are achieved.

[0017] Third, the temperature sensor transmits the collected electrical signal to the controller. After receiving the signal from the temperature sensor, the controller compares it with the preset temperature value. When the temperature in the corresponding zone is higher, the solenoid valve opens the return pipe, allowing the internal gas to enter the return gas port of the refrigeration unit for further cooling. By circulating the cold air in the compartment, the efficiency of the cooling process is ensured. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0026] A circulating energy-saving ring cooler drive control device includes an annular cold compartment 1, with a support 2 embedded at the center of the annular cold compartment 1. The support 2 is a circular hollow structure, with one end of six fixed columns 10 evenly fixedly installed sequentially on the outer circumferential wall of the support 2, and the other ends of the six fixed columns 10 being circumferentially fixedly installed on the inner circumferential wall of the annular cold compartment 1. The annular cold compartment 1 is circular and has circumferential grooves on its outer circumferential wall. Partition plates 3 extending into the compartment of the annular cold compartment 1 are evenly slidably arranged on the support 2. A continuous circumferential groove is opened on the outer circumferential wall of the support 2, and each partition plate 3 slides within its respective groove. Simultaneously, the partition plates 3 extend into the inner cavity of the annular cold compartment 1, dividing the annular cold compartment 1 into independent compartments through the multiple circumferential partition plates 3.

[0027] The inner cavity of the support 2 is equipped with a partition control component for independently controlling the retraction and extension of each partition 3. A refrigeration unit 4 is fixedly connected to the top of the support 2, and output pipes 5 extending into each cold zone are evenly distributed at the output end of the refrigeration unit 4. The refrigeration unit 4 is fixed to the top of the support 2 by a frame. Five output pipes 5 branch off from the cold air outlet of the refrigeration unit 4 through a main pipe. These five output pipes 5 are respectively embedded in the cold compartments divided within the annular cold compartment 1 by the partitions 3. The extension length of each partition 3 into the annular cold compartment 1 is controlled by the partition control component.

[0028] During the refrigeration process, in areas without goods, the corresponding independent zone control components isolate these areas and simultaneously shut off the corresponding output pipes 5, concentrating the cold air towards the areas with goods. By controlling each independent zone partition 3 according to the location of the goods, the energy consumption of the refrigeration unit 4 is reduced, and cold air is prevented from being discharged into areas without goods. By directing the cooling energy into areas with concentrated goods, energy-saving effects are achieved, avoiding excessive cooling output.

[0029] The partition plate 3 divides the annular cold compartment 1 into various cold zones, each embedded with a temperature sensor 7. Each output pipe 5 is equipped with a solenoid valve connected to the respective temperature sensor 7. The controller can be a PLC (Programmable Logic Controller), a microcontroller, or other specialized temperature control instruments. Transmission can be wired, such as through shielded cables to reduce electromagnetic interference, or wireless, such as using Bluetooth or ZigBee wireless communication technologies, suitable for situations where wiring is inconvenient.

[0030] Temperature sensor 7 monitors the temperature in each cooling zone in real time and converts the temperature signal into an electrical signal. Temperature sensor 7 transmits the collected electrical signal to the controller. Upon receiving the signal from temperature sensor 7, the controller compares it with a preset temperature value. When temperature sensor 7 detects that the temperature is within the cooling range, the solenoid valve closes the output pipe 5 in the corresponding zone. When temperature sensor 7 detects that the temperature in the zone is higher than the preset temperature value, the solenoid valve opens, allowing cold air to continue entering. This automatic control of cold air input achieves energy-saving effects.

[0031] It is worth noting that the return air port of the refrigeration unit 4 is equipped with a manifold 8. The outer wall of the manifold 8 is uniformly provided with return pipes 6 extending into each cold zone of the annular cold compartment 1, and each return pipe 6 is equipped with a solenoid valve connected to each temperature sensor 7. When the temperature sensor 7 detects that the temperature in the corresponding cold zone is high, the temperature sensor 7 converts the temperature signal into an electrical signal.

[0032] Temperature sensor 7 transmits the collected electrical signal to the controller. After receiving the signal from temperature sensor 7, the controller compares it with the preset temperature value. When the temperature is high, the solenoid valve opens the return pipe 6, allowing the internal gas to enter the return gas port of the refrigerator 4 through the return pipe 6 for further cooling. By circulating the cold air inside the chamber, the efficiency of the cooling process is ensured.

[0033] In addition, a sleeve 13 is fitted onto the outer wall of the return pipe 6 and fixed to the annular cold compartment 1. The sleeve 13 is fixed to the annular cold compartment 1 and is fixedly fitted onto the outer wall of the return pipe 6 through a central mounting hole, thereby improving the stability of the return pipe 6.

[0034] Additionally, the zone control assembly includes an electric push rod 15 circumferentially and uniformly fixed to the support 2, with a pushing member 11 fixedly connected to the movable end of the electric push rod 15. A force-bearing member 14 is provided on one side of the zone partition 3 extending into the inner cavity of the support 2. The side wall of the force-bearing member 14 has an inclined surface that contacts the pushing member 11, and the force-bearing member 14 is connected to the inner wall of the support 2 via an elastic member. The outer cylindrical end of the electric push rod 15 is vertically fixed to the surface of the base frame 17, which is fixedly installed at the bottom of the inner wall of the support 2. The spherical pushing member 11 is fixedly installed at the movable end of the electric push rod 15.

[0035] Furthermore, the elastic member includes a connecting frame 16 fixed between the force-bearing member 14 and the partition plate 3, and the connecting frame 16 is connected to the inner wall of the support 2 via an elastic member 12. The elastic member 12 can be a compression spring, and its two ends are respectively fixed to the inner wall of the support 2 and the surface of the connecting frame 16. A wedge-shaped locking block with an inclined surface facing the pushing member 11 is fixedly installed on the other side of the connecting frame 16.

[0036] After the electric push rod 15 is connected to the power supply through the wire, the movable end of the electric push rod 15 drives the spherical pusher 11 to slide against the inclined surface of the wedge-shaped force-receiving member 14. As the pusher 11 moves, the surface of the force-receiving member 14 is subjected to force, which drives the partition plate 3 to move, so that the partition plate 3 extends into the interior of the annular cold chamber 1, thereby dividing the annular cold chamber 1 into sections and separating the corresponding materials.

[0037] The bottom of the annular cold storage 1 is uniformly fixed with docking seats 9. The docking seats 9 have mounting holes, which facilitates the operation process for relevant personnel. First, the annular cold storage 1 is placed inside the material area, so that the opening of the annular cold storage 1 faces the annular material area, and then the annular cold storage 1 is fixed in the corresponding position by the docking seats 9.
