Description

Technical Field

[0001] This utility model relates to the field of zinc oxide cooling technology, and in particular to a cooling device for high-temperature zinc oxide materials. Background Technology

[0002] Zinc oxide is an oxide of zinc and a commonly used chemical additive. It is widely used in the production of products such as plastics, silicate products, synthetic rubber, lubricants, paints, ointments, adhesives, food, batteries, and flame retardants. Most zinc oxide is obtained by calcining zinc carbonate and then indirectly electrolyzing it. The manufacturing process requires multiple steps, including calcination, cooling, and transportation and collection, to obtain the finished zinc oxide product. After high-temperature calcination, zinc oxide needs to be cooled before it can be collected.

[0003] Existing patent application publication number CN216845762U discloses a cooling device for zinc oxide processing, including a cooling box and a support frame fixedly installed inside the cooling box. An air guide duct is fixedly installed on the peripheral wall of the support frame, and a cold air duct is fixedly installed on the outer wall of the cooling box. One end of the cold air duct is connected to an external air supply device. The cooling box is vertical, with cooling chambers arranged from top to bottom inside. Each cooling chamber has an air guide duct on its peripheral wall and is connected to a cold air duct to guide cold air from the periphery to the center, mixing it with the zinc oxide powder inside the cooling chamber for cooling. A temperature sensor is also installed inside the cooling chamber, and the temperature can be set in multiple levels according to the number of cooling chambers to accelerate the overall cooling speed. The device utilizes the cold air to fully exchange heat with the zinc oxide powder, achieving rapid heat dissipation and thus accelerating production. However, this cooling device only uses air cooling to cool the zinc oxide, resulting in a long cooling time and reduced production efficiency.

[0004] Therefore, we propose a cooling device for high-temperature zinc oxide materials. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling device for high-temperature zinc oxide materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A cooling device for high-temperature zinc oxide materials includes a cooling box with a feed inlet at the top. A stirring motor is located below the feed inlet inside the cooling box. A propeller blade is mounted on the drive end of the stirring motor, and a spiral guide plate is located below the stirring motor. Air-cooling components are evenly arranged on both sides of the outer end of the cooling box. A zinc oxide conveying component is located at the discharge end of the spiral guide plate inside the cooling box. A mist-cooling component is located at the top of the cooling box. The stirring motor drives the propeller blade to rotate, thereby breaking up agglomerated zinc oxide materials to improve cooling efficiency. The spiral guide plate guides the broken material to the conveying component for transport. The spiral shape also reduces the falling speed of the material, thus improving the cooling effect of the air-cooling component.

[0007] As a further embodiment of this utility model: the air-cooling component includes an air-cooling box, and several air-cooling boxes are evenly arranged on both sides of the outer end of the cooling box. An air inlet is provided at the end of the air-cooling box away from the cooling box. A dustproof net is provided inside the air inlet. An axial flow fan is provided inside the air-cooling box. The axial flow fan can blow cold air from the outside into the cooling box, thereby rapidly cooling the high-temperature material.

[0008] As a further embodiment of this utility model: the zinc oxide conveying assembly includes sprockets, and several sprockets are arranged laterally inside the cooling box at the discharge end of the spiral guide plate, with chains meshing at the outer ends of the sprockets.

[0009] As a further embodiment of this utility model: a conveyor belt is provided at the outer end of the chain, and a conveyor motor is provided at the outer end of the cooling box. The drive shaft of the conveyor motor passes through the cooling box and is connected to the sprocket. The conveyor motor can drive the sprocket to drive the chain to rotate, thereby driving the conveyor belt to rotate, which facilitates the transportation of zinc oxide materials.

[0010] As a further embodiment of this utility model: the mist cooling component includes a cooling water tank, the upper end of which is provided with a cooling water tank, and the lower end of which is provided with a water pump. The cooling water tank can store cooling water, and the water pump can extract the cooling water to cool the high-temperature materials.

[0011] As a further improvement of this utility model: a water supply pipe is provided at the water outlet of the lower end of the water pump, and a plurality of atomizing nozzles are evenly arranged at the lower end of the water supply pipe. The atomizing nozzles are located above the conveyor belt. The cooling water can be atomized and sprayed onto the zinc oxide material through the atomizing nozzles. The water mist mixes with the material, and the material is rapidly cooled by absorbing heat through water evaporation.

[0012] As a further improvement of this utility model: the cooling box is equipped with several temperature probes, which are distributed at the feed end, middle and discharge end of the cooling box. A control switch is provided at the front end of the cooling box, and a display screen is provided at the front end of the control switch. By setting the temperature probes, the temperature of zinc oxide material at different positions in the cooling box can be measured, and the temperature data can be displayed on the display screen, making it convenient to control the cooling power through the control switch.

[0013] Compared with the prior art, this utility model provides a cooling device for high-temperature zinc oxide materials, which has the following beneficial effects: 1. This utility model uses a stirring motor to drive a propeller blade to rotate, thereby breaking up agglomerated zinc oxide materials, avoiding insufficient local cooling and improving cooling efficiency. The spiral guide plate extends the residence time of the material in the air-cooling zone, and the conveyor belt conveys the material at a uniform speed so that the material is evenly subjected to atomized cooling, ensuring a consistent overall cooling effect. The air-cooling component provides continuous cold air through an axial flow fan, and the atomized cooling component utilizes the evaporation of atomized water to absorb heat. The two methods work together to significantly shorten the cooling time compared to air cooling alone, improve production efficiency, and enhance the practicality of the cooling device for high-temperature zinc oxide materials.

[0014] 2. This utility model, through temperature probes installed at the inlet, middle and outlet of the cooling box, can measure the temperature of zinc oxide material at different locations in the cooling box and display it intuitively on the display screen. Operators can flexibly adjust the cooling parameters through control switches to adapt to materials with different initial temperatures, ensure stable discharge temperature, and improve the performance of the cooling device for high-temperature zinc oxide materials.

The stirring motor 3 drives the propeller blade 4 to rotate, thereby breaking up agglomerated zinc oxide materials to improve cooling efficiency. The spiral guide plate 5 guides the broken material to the zinc oxide conveying component 7 for transport. Simultaneously, the spiral shape reduces the falling speed of the material, thereby improving the cooling effect of the air-cooling component 6.

[0021] In this embodiment, the preferred air-cooling component 6 includes an air-cooled box 61. Several air-cooled boxes 61 are evenly arranged on both sides of the outer end of the cooling box 1. An air inlet 62 is provided at the end of the air-cooled box 61 away from the cooling box 1. A dustproof net 63 is provided inside the air inlet 62. An axial flow fan 64 is provided inside the air-cooled box 61. The axial flow fan 64 can blow cold air from the outside into the cooling box 1, thereby rapidly cooling the high-temperature material.

[0022] In this embodiment, the preferred zinc oxide conveying assembly 7 includes sprockets 71. Several sprockets 71 are arranged laterally inside the cooling box 1 at the discharge end of the spiral guide plate 5, and chains 72 are engaged at the outer ends of the sprockets 71.

[0023] In this embodiment, preferably, the outer end of the chain 72 is provided with a conveyor belt 73, and the outer end of the cooling box 1 is provided with a conveyor motor 74. The drive shaft of the conveyor motor 74 passes through the cooling box 1 and is connected to the sprocket 71. The conveyor motor 74 can drive the sprocket 71 to drive the chain 72 to rotate, thereby driving the conveyor belt 73 to rotate, which facilitates the transportation of zinc oxide materials.

[0024] In this embodiment, the preferred mist cooling component 8 includes a cooling water tank 81. The upper end of the cooling box 1 is provided with a cooling water tank 81, and the lower end of the cooling water tank 81 is provided with a water pump 82. The cooling water tank 81 can store cooling water, and the water pump 82 can pump out the cooling water to cool the high-temperature materials.

[0025] In this embodiment, the lower end of the water pump 82 is preferably provided with a water supply pipe 83. A plurality of atomizing nozzles 84 are evenly arranged at the lower end of the water supply pipe 83. The atomizing nozzles 84 are located above the conveyor belt 73. The cooling water can be atomized and sprayed onto the zinc oxide material through the atomizing nozzles 84. The water mist mixes with the material, and the material is rapidly cooled by absorbing heat through water evaporation.

[0026] In this embodiment, the cooling box 1 preferably has a plurality of temperature probes 9 inside. The temperature probes 9 are distributed at the feed end, middle and discharge end of the cooling box 1. A control switch 10 is provided at the front end of the cooling box 1, and a display screen 11 is provided at the front end of the control switch 10.

The temperature data can be displayed on the display screen 11, and the cooling power can be controlled by the control switch 10.

[0027] Working Principle: In this embodiment, the high-temperature zinc oxide material cooling device is used by feeding the high-temperature zinc oxide material into the cooling box 1 through the inlet 2. The material falls above the stirring motor 3, which starts and drives the propeller blades 4 to rotate at high speed, breaking up any clumps of material and increasing the contact area between the material and the cooling medium, thus preparing for subsequent cooling. The broken material falls onto the spiral guide plate 5 and is slowly conveyed downwards along the spiral path, thereby reducing the falling speed and extending the cooling time. At the same time, the air-cooling components 6 on both sides of the outer end of the cooling box 1 are activated. The axial flow fan 64 inside the air-cooling box 61 draws in outside air through the air inlet 62 and blows the cold air into the cooling box 1, where it exchanges heat with the material on the spiral guide plate 5, achieving initial cooling. The material that has undergone initial cooling falls from the spiral guide plate 5. The material falls onto the conveyor belt 73 of the zinc oxide conveying assembly 7 at the discharge end. The conveying motor 74 drives the sprocket 71 to rotate, and the sprocket 71 drives the chain 72 and the conveyor belt 73 to move forward, conveying the material forward. At this time, the mist cooling assembly 8 is started. Water in the cooling water tank 81 is drawn out by the water pump 82 and transported to the atomizing nozzle 84 through the water pipe 83. The atomizing nozzle 84 atomizes the water and sprays it onto the surface of the material on the conveyor belt 73. The water mist evaporates and absorbs heat, deeply cooling the material. The temperature probe 9 inside the cooling box 1 monitors the material temperature in real time. The data is transmitted to the control switch 10 and displayed on the display screen 11. The operator can adjust the wind speed of the axial flow fan 64, the speed of the conveying motor 74, or the water supply of the water pump 82 through the control switch 10 according to the temperature data to ensure stable cooling effect.
