Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, specifically a cooling equipment for calcium carbide production. Background Technology

[0002] Calcium carbide is an important chemical raw material, widely used in acetylene production, metal smelting, and organic synthesis. Calcium carbide is typically produced by high-temperature calcination of limestone and coke in an electric arc furnace, and it must be cooled before being used in subsequent processes.

[0003] Calcium carbide is transported from the furnace outlet to the cooling equipment by a rail transport vehicle. A high-powered fan forces outside air into the cooling chamber, and the high-speed airflow penetrates the gaps between the calcium carbide blocks, resulting in forced convection heat transfer and thus lowering the calcium carbide's temperature. However, existing cooling equipment has a fixed fan direction, and the dense packing of the granules causes a difference in cooling effect between the outer and inner sides of the calcium carbide, resulting in locally excessively high temperatures and affecting the cooling rate. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a cooling device for calcium carbide production, which has the following beneficial effects:

[0017] In this invention, after the calcium carbide particles fall onto the concave plate and pass through the square opening, they continue to fall. At this time, the first motor drives the first synchronous wheel and the stirring rod to rotate, loosening the particles and facilitating contact with the cooling airflow. During the fall, the particles contact the baffle plate, extending the descent and ensuring sufficient contact with the cold air. Simultaneously, the first synchronous wheel drives the second synchronous wheel, the first transmission rod, and the cam to rotate via a synchronous transmission belt. The irregular cam pushes the baffle plate to swing up and down, preventing particle accumulation. This design allows the particles to fully contact the cold air within the cooling chamber, extending the residence time and improving the cooling efficiency. Attached Figure Description

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0025] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0026] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0027] After calcium carbide is transported into the cooling box by a railcar, a high-speed airflow is sent through the gaps between the stacked calcium carbide by a fixed-direction fan to achieve forced convection cooling.

[0028] In related technologies, the direction of airflow from the fan in existing cooling equipment is fixed, and due to the excessively dense packing of granules, there is a difference in cooling effect between the outer and inner sides of the calcium carbide, resulting in excessively high local temperatures and affecting the cooling rate.

[0029] To address some of the problems in related technologies, this application provides a cooling device for calcium carbide production. When needed, calcium carbide particles fall onto a concave plate 2 and continue falling through a square opening 201. During this process, the output of a first motor 301 drives a first synchronous wheel 302 to rotate, which in turn drives a stirring rod 303 located on the upper part of the concave plate 2 to rotate, making the particles more loosely distributed in the cooling box 1, which facilitates full contact with the cooling airflow and improves cooling efficiency. After falling from the square opening 201, the particles contact a baffle plate 308, which prolongs the falling process, allowing them to fully contact the cold air blown out by the blower 102. Meanwhile, the first synchronous pulley 302 transmits power to the second synchronous pulley 305 through the synchronous transmission belt 304, which drives the first transmission rod 306 and the cam 307 fixed at one end to make circular motion. Since the cam 307 is an irregular circle, it continuously contacts the baffle plate 308 when rotating, pushing the baffle plate 308 to swing up and down, thus preventing the granules from accumulating on the baffle plate 308.

[0030] This application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Reference Figure 1-4 This utility model provides a cooling device for calcium carbide production, including a cooling box 1. The top of the cooling box 1 is provided with a feed inlet 101. A blower 102 is fixedly connected to the top of the cooling box 1. One end of the blower 102 is connected to a pressurized air outlet 103. The bottom of the cooling box 1 is fixedly connected to a discharge outlet 104. An auxiliary cooling mechanism 3 is provided inside the cooling box 1. The auxiliary cooling mechanism 3 includes a first motor 301. The output end of the first motor 301 is driven to a first synchronous pulley 302. The surface of the first synchronous pulley 302 is driven to a synchronous transmission belt 304. The movement of the synchronous transmission belt 304 is driven to a second synchronous pulley 305. One end of the second synchronous pulley 305 is fixedly connected to a first transmission rod 306. One end of the first transmission rod 306 is fixedly connected to a cam 307. The top of the cam 307 is attached to a baffle plate 308. The two sides of the baffle plate 308 are connected to the cooling box 1 through a rotating shaft.

[0032] Calcium carbide particles enter the cooling box 1 through the feed inlet 101. The blower 102 blows cooling air into the box through the pressurized air outlet 103 to cool the particles.

[0033] Calcium carbide particles fall onto the concave plate 2 and continue falling through the square opening 201. During this process, the output of the first motor 301 drives the first synchronous pulley 302 to rotate, which in turn drives the stirring rod 303 to rotate. The stirring rod 303 is located on the upper part of the concave plate 2, which allows the particles to be more loosely distributed in the cooling box 1, facilitating full contact between the cooling airflow and the particles and improving cooling efficiency. After the particles fall through the square opening 201, they come into contact with the baffle plate 308. The baffle plate 308 extends the falling process of the particles, allowing them to fully contact the cold air blown out by the blower 102. At this time, the first synchronous pulley 302 drives the motor through the synchronous transmission belt 304. Force is transmitted to the second synchronous pulley 305, causing it to rotate synchronously. When the second synchronous pulley 305 rotates, it drives the first transmission rod 306, which is fixedly connected to it, to rotate. This causes the cam 307, which is fixed at one end of the first transmission rod 306, to perform a circular motion. The cam 307 contacts the baffle plate 308. The cam 307 is an irregular circle. During the rotation, the surface of the cam 307 continuously contacts the baffle plate 308, thereby pushing the baffle plate 308 to swing up and down continuously. This prevents the granules from accumulating on the baffle plate 308. After being disturbed by the baffle plate 308, the granules continue to fall to the bottom of the cooling box 1 and are agitated by the spiral blades 402, thereby reducing the temperature of the granules.

[0034] The baffle plate 308 is a flow guide plate installed below the concave plate 2. When calcium carbide particles fall from the square opening 201, they will impact the surface of the baffle plate 308. Because there is a slope between the baffle plate 308 and the inner wall of the cooling box 1, the particles will not fall directly vertically, but will slide along the plate surface, thereby prolonging their residence time in the cooling airflow.

[0035] The baffle plate 308 is installed directly below the square opening 201. Its connection point with the inner wall of the cooling box 1 is located at the upper end of the baffle plate 308. Due to the high connection point, the main impact and sliding area of ​​calcium carbide particles is concentrated in the lower middle part of the baffle plate 308. There is no risk of particles being stuck at the connection point. There is a three-centimeter gap between the two sides of the baffle plate 308 and the cooling box 1, so there is no risk of fine materials getting stuck.

[0036] The airflow from the blower 102 enters the cooling box 1 through the pressurized air outlet 103. The baffles 308 are not sealed together, and the oscillation of the baffles 308 will create a local low-pressure area, which enhances the penetration of the airflow into the granules and ensures that there is always cooling airflow in the cooling box 1.

[0037] In a preferred embodiment, a concave plate 2 is fixedly connected to the inner wall of the cooling box 1. A square opening 201 is provided in the recess of the concave plate 2. A stirring rod 303 is provided at the top of the square opening 201. One end of the stirring rod 303 is fixedly connected to the first synchronous wheel 302.

[0038] The stirring action of the stirring rod 303 can prevent the calcium carbide particles from accumulating too densely at the concave plate 2, so that the particles can be more loosely distributed in the cooling box 1, which is conducive to the full contact between the cooling airflow and the particles and improves the cooling efficiency.

[0039] In a preferred embodiment, a partition plate 5 is fixedly connected to the inner side wall of the cooling box 1, a second transmission rod 401 is provided on the top of the partition plate 5, a second motor 4 is connected to one end of the second transmission rod 401, the second motor 4 is fixedly connected to the outer side wall of the cooling box 1, and a spiral blade 402 is fixedly connected to the surface of the second transmission rod 401.

[0040] The second motor 4 starts and drives the second transmission rod 401 connected to it to rotate. When the second transmission rod 401 rotates, the spiral blades 402 fixedly connected to its surface also rotate. The spiral blades 402 continuously stir in the cooling box 1, turning the bottom granules to the top, ensuring that the granules are all blown by the cold air, thus improving the uniformity and efficiency of cooling.

[0041] In a preferred embodiment, the bottom of the partition plate 5 is provided with an air outlet chamber 502, and air holes 501 are provided on both sides of the air outlet chamber 502. A fan 503 is connected to the outside of the air holes 501 by bolts.

[0042] During the cooling process, the fan 503 starts, drawing the hot air from the air outlet 502 at the bottom of the partition plate 5 through the air hole 501 and discharging it to the outside of the cooling box 1, thus preventing the hot air from accumulating inside the cooling box 1 and further improving the cooling efficiency.

[0043] In a preferred embodiment, the surface of the partition plate 5 is provided with through holes, the diameter of which is smaller than that of the calcium carbide granules.

[0044] When the calcium carbide granules flow in the cooling box 1, the granules will not fall through the through holes because the diameter of the through holes on the surface of the partition plate 5 is smaller than that of the calcium carbide granules. However, air can flow out through these through holes, which facilitates the exhaust of internal air and improves the cooling effect.

[0045] In a preferred embodiment, the length of the spiral blade 402 is less than the width of the cooling box 1, ensuring that the granules can flow sufficiently in the cooling box 1.

[0046] In a preferred embodiment, the exhaust direction of the fan 503 is towards the outside of the cooling box 1. When the fan 503 is running, it draws out the hot air in the air outlet chamber 502 at the bottom of the partition plate 5 through the air hole 501 and discharges it towards the outside of the cooling box 1, so as to prevent the hot air from flowing back into the cooling box 1.

[0047] In a preferred embodiment, two sets of spiral blades 402 are used together, and the spiral directions of the two sets of spiral blades 402 are opposite. The bidirectional flow can make the distribution of granules in the cooling box 1 more uniform, and avoid local granule accumulation or insufficient cooling.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
