[0022] 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.

[0023] Example 1:

[0024] Please see Figure 1-4 A cooling device for calcium oxide production includes a cooling box 1. A cabinet door 2 is hinged to the front end of the cooling box 1. Four sets of columns 6 are fixedly connected to the bottom end of the cooling box 1. A feed inlet 3 is fixedly connected to the top end of the cooling box 1. A first baffle 7 and a second baffle 8 are rotatably connected to the feed inlet 3. A first fan 13 is installed at the top end of the cooling box 1, and a second fan 14 is installed at the lower end of one side of the cooling box 1. A collecting mechanism 12 is installed on the exterior of both the first fan 13 and the second fan 14. A first crushing unit is rotatably connected inside the cooling box 1. The first crushing roller 16 and the second crushing roller 17 are meshed with each other. A filter screen 18 is provided below the first crushing roller 16 and the second crushing roller 17. The first fan 13 blows air into the cooling box 1, and the second fan 14 exhausts air out of the cooling box 1. The operation of the first fan 13 and the second fan 14 accelerates the air circulation in the cooling box 1, which is beneficial to improving the cooling effect of the equipment. A collection mechanism 12 is installed on the outside of the first fan 13 and the second fan 14 to collect the calcium oxide powder that overflows from the equipment.

[0025] The bottom ends of the first baffle 7 and the second baffle 8 are respectively rotatably connected to a support mechanism 20. The other end of the support mechanism 20 is rotatably connected to the feed inlet 3. Each set of support mechanisms 20 includes a sleeve 2002. A slide rod 2001 is slidably connected to the sleeve 2002. A spring 2003 is fixedly connected to one end of the slide rod 2001. The other end of the spring 2003 is fixedly connected to the sleeve 2002. The spring 2003 drives the slide rod 2001 to close the first baffle 7 and the second baffle 8. When there is no raw material at the top of the first baffle 7 and the second baffle 8, they remain closed to prevent powder from drifting into the air. When feeding material, the spring 2003 is compressed and rotates, causing the first baffle 7 and the second baffle 8 to rotate, allowing the raw material to enter the cooling box 1.

[0026] The two sets of collection mechanisms 12 include a collection cover 1201, which is threadedly connected to the cooling box 1. The collection cover 1201 and the cooling box 1 are not sealed. The inner diameter of the collection cover 1201 is larger than the diameter of the first fan 13 and the second fan 14. There is a gap between the collector 1201 and the cooling box 1 to allow air to enter without affecting the operation of the first fan 13 and the second fan 14.

[0027] One end of the collection cover 1201 is fixedly connected to a conveying pipe 1202, and the other end of the conveying pipe 1202 is inserted into a water tank 1203. One set of the water tanks 1203 is fixedly connected to the cooling box 1, and the other set of the water tanks 1203 is placed on the ground. The water tanks 1203 are filled with water, and the water level is higher than the opening of the conveying pipe 1202. The calcium oxide powder floating out of the equipment is forced to react with the water through the conveying pipe 1202 by the first fan 13 and the second fan 14 to generate calcium hydroxide. The calcium oxide powder is recycled, which helps to reduce environmental pollution, improve resource utilization, and reduce resource waste.

[0028] In this embodiment, the operation of the first fan 13 and the second fan 14 accelerates the air circulation within the cooling box 1, which is beneficial to improving the cooling effect of the equipment. The first fan 13 and the second fan 14 cause the calcium oxide powder that floats out of the equipment to react with water through the conveying pipe 1202 to generate calcium hydroxide, thus recovering the calcium oxide powder. By setting a support mechanism 20 at the bottom of the first baffle 7 and the second baffle 8 that can retract according to weight changes, the opening and closing state of the first baffle 7 and the second baffle 8 can be controlled according to usage requirements. This helps to prevent dust from drifting into the factory through the feed inlet 3 during the crushing process, which helps to reduce environmental pollution, improve resource utilization, and reduce resource waste.

[0029] Example 2:

[0030] Please see Figure 1-3This embodiment provides a technical solution based on embodiment one: a motor 15 is fixedly connected to the upper end of one side of the cooling box 1, the output end of the motor 15 passes through the cooling box 1 and is fixedly connected to the first crushing roller 16, the filter screen 18 is fixedly connected to the inner wall of the cooling box 1, and a guide block 19 is fixedly connected to the top of the filter screen 18; the first crushing roller 16 is driven to rotate by the drive motor 15, and the first crushing roller 16 rotates and meshes with the second crushing roller 17 to crush the calcium oxide put into the cooling box 1. By setting the filter screen 18 at the bottom, the calcium oxide that meets the crushing requirements falls into the cooling box 1. The calcium oxide that cannot pass through the filter screen 18 will be rolled up and crushed again by the first crushing roller 16 and the second crushing roller 17 until it passes through the filter screen 18, so that the crushed calcium oxide is more uniform, which is beneficial to improving the cooling and heat dissipation effect of the equipment. By setting the guide block 19, it is convenient to put the crushed calcium oxide into the cooling plate 11 below.

[0031] Three sets of cooling plates 11 are fixedly connected to the inner wall of the cooling tank 1. Each of the three sets of cooling plates 11 has a cavity inside. The three sets of cooling plates 11 are respectively connected to a water inlet 9 and a water outlet 10. Coolant is delivered to the cooling plates 11 through the water inlet 9 and discharged from the cooling plates 11 through the water outlet 10. Calcium oxide falls onto the cooling plates 11 and exchanges heat with the cold water inside the cooling plates 11, thereby reducing the temperature of the calcium oxide. The cooling plates 11 are staggered.

[0032] The bottom of the cooling box 1 is provided with a discharge port 4, and a guide plate 5 is fixedly connected to the discharge port 4. The cooled calcium oxide is discharged into the cooling box 1 by setting the guide plate 5.

[0033] In this embodiment, the first crushing roller 16 is driven to rotate by the drive motor 15. The rotation of the first crushing roller 16 engages with the rotation of the second crushing roller 17 to crush the calcium oxide inside the cooling tank 1. By setting a filter screen 18 at the bottom, the calcium oxide that meets the crushing requirements falls into the cooling tank 1, making the crushed calcium oxide more uniform, which is beneficial to improving the cooling and heat dissipation effect of this equipment. By setting a guide block 19, it is easy to put the crushed calcium oxide into the cooling plate 11 below. Coolant is transported to the cooling plate 11 through the water inlet 9 and discharged from the cooling plate 11 through the water outlet 10. The calcium oxide falls onto the cooling plate 11 and exchanges heat with the cold water in the cooling plate 11, thereby reducing the temperature of the calcium oxide and further improving the cooling effect of the calcium oxide.
