Description

Technical Field

[0001] The utility model relates to the technical field of pellet conveying, in particular to a pellet cooling conveyor. Background Art

[0002] Pellet ore is a regularly shaped pellet with a size of 8-16mm. It has a more uniform particle size than sintered ore, more micropores, better reducibility, better strength at room temperature, and is easy to store, which is beneficial to strengthening blast furnace production. In the process of pellet production, the roasted pellets need to be cooled, and after cooling, the finished products that meet the specifications are screened.

[0003] For example, a rapid cooling device with Chinese patent number CN219368412U is disclosed. In this utility model, the pellets above the chain plate are sprayed by multiple sprayers, so that the surface of the pellets contacts water to produce an evaporation reaction, which causes the temperature of the pellets to drop rapidly. The exhaust fan is started to discharge the high temperature generated by the evaporation reaction inside the cooling box. However, this setting effect can easily cause the high-temperature pellets to directly contact the low-temperature water liquid, which can easily cause the pellets to crack, resulting in an increase in the defective rate, which is not conducive to user use. In addition, this method will cause a large amount of water resources to be wasted, increase the cost of use, and is not conducive to user use. Therefore, a pellet cooling conveyor is proposed to solve the above problems. Utility Model Content

[0014] (3) Beneficial effects

[0015] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0016] 1. The pellet cooling conveyor provides dual airflows to cool the high-temperature pellets by arranging the first and second fans, thereby avoiding the thermal expansion and contraction effect caused by direct contact between low-temperature objects and high-temperature pellets, thereby preventing the high-temperature pellets from cracking after cooling, thereby ensuring the production quality of the pellets.

Moreover, through the setting of the gas gathering hood, most of the cold air flow can enter the interior of the gas diversion pipe, and flow to part of the gas to cool the heat emitted by the semiconductor refrigeration sheet, and blow the hot air out of the interior of the processing box, further ensuring the normal operation of each electrical component and facilitating the normal progress of the cooling operation.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3A pellet cooling conveyor in this embodiment includes an outer shell 1, a chain conveyor body 2 is installed inside the outer shell 1, a collecting box 3 is provided on the right side of the outer shell 1, and cooling components 4 are installed on the inner and outer sides of the outer shell 1.

[0024] exist Figure 1-3 In the figure, the cooling component 4 is composed of eleven components, namely, a first fan 401, a processing box 402, a second fan 403, a guide plate 404, a semiconductor refrigeration plate 405, a baffle 406, a water pump 407, a return pipe 408, a gas diversion pipe 409, a gas collection cover 410 and a coolant 411, so as to achieve the advantages of reducing contact, facilitating cooling and reducing costs.

[0025] exist Figure 1 and Figure 2 In the figure, a first fan 401 is installed on the left side of the outer shell 1, a processing box 402 is installed on the top of the outer shell 1, and a second fan 403 is installed on the left side of the processing box 402. Air cooling is used to accelerate the flow rate of gas inside the outer shell 1 and the processing box 402.

[0026] exist Figure 2 and Figure 3 In the figure, a guide plate 404 is installed on the inner right wall of the processing box 402, and a semiconductor refrigeration plate 405 is connected to the inside of the guide plate 404 to cool the coolant 411 flowing through the top of the guide plate 404, thereby reducing the liquid temperature.

[0027] exist Figure 2 In the process, a baffle 406 is installed on the inner bottom wall of the processing box 402, a water pump 407 is installed on the right side of the processing box 402, and a return pipe 408 is installed at the output nozzle of the water pump 407. The baffle 406 is used to prevent the coolant 411 from flowing back to the second fan 403 and interfering with the air cooling, and to ensure the liquid level of the coolant 411 inside the processing box 402, so that the water pump 407 can stably pump the water for transportation.

[0028] exist Figure 2 In the figure, a gas diversion pipe 409 is installed on the inner top wall of the outer shell 1, and a gas collecting hood 410 is installed at the air inlet of the gas diversion pipe 409. A coolant 411 is provided between the inner right wall and the inner bottom wall of the processing box 402 and the right side of the baffle block 406, which is used to facilitate part of the cold air flow to enter the gas collecting hood 410 and flow into the gas diversion pipe 409, thereby being dispersed above the chain conveyor body 2 to cool down each pellet ore body.

[0029] It should be noted that this section is intended to provide a background or context for the implementation methods stated in the claims, and omits detailed descriptions of known functions and known components. At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods adopted are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art just because it is included in this section.

[0030] During implementation, follow these steps:

[0031] 1) First, start the semiconductor refrigeration chip 405 and start the water pump 407 to suck the cooling liquid 411 through the return pipe 408 and transport it to the top of the guide plate 404, so that the cooling liquid 411 is cooled by the semiconductor refrigeration chip 405;

[0032] 2) Then, the coolant 411 flows downward along the guide plate 404 to form a 'water curtain'. The first fan 401 and the second fan 402 are then turned on, allowing the airflow from the second fan 402 to pass through the water curtain. After cooling, part of the cold airflow enters the air collection hood 410.

[0033] 3) Finally, the cold air flows along the gas diversion pipe 409 and is dispersed to the outer surface of each pellet. Then the first fan 401 continues to blow air to cool the pellets.

[0034] In summary, the pellet cooling conveyor, by arranging the first fan 401 and the second fan 403, provides dual airflows to cool the high-temperature pellets, thereby avoiding the thermal expansion and contraction effect caused by the direct contact of low-temperature objects with the high-temperature pellets, and further preventing the high-temperature pellets from cracking after cooling, thereby ensuring the production quality of the pellets. At the same time, the water pump 407 and the return pipe 408 are arranged to continuously circulate the liquid, forming a "water curtain" between the guide plate 404 and the baffle block 406, thereby cooling the airflow passing through. This arrangement can reduce the evaporation of liquid, reduce the consumption efficiency of the coolant 411, and further reduce the cost of use for users.

[0035] Moreover, by utilizing the setting of the semiconductor refrigeration plate 405, the coolant 411 on the top of the guide plate 404 can be continuously cooled to make its temperature lower, so that after the water curtain is formed, the temperature of the air flow passing through the water curtain can be reduced, and the air flow passing through the water curtain is converted into a cold air flow, thereby ensuring the cooling effect on the high-temperature pellets. In addition, through the setting of the gas collecting hood 410, most of the cold air flow can enter the interior of the gas diversion pipe 409, and flow to part of the gas to cool the heat emitted by the semiconductor refrigeration plate 405, and blow the hot air out of the interior of the processing box 402, further ensuring the normal operation of each electrical component, facilitating the normal progress of the cooling operation, and solving the problem in the comparative document that the low-temperature liquid is in direct contact with the high-temperature solid, which easily causes thermal expansion and contraction to cause cracking, and at the same time causes a large amount of water resources to be wasted.
