[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The following is combined with Figure 1-4 To further explain this application in detail,
[0023] The embodiment of the present application discloses a grate plate of a grate cooler with a simple structure, comprising a grate plate body 1, a cavity 2 is arranged inside the grate plate body 1, a diffusion hopper 3 is fixedly installed inside the cavity 2, a plurality of vertical holes 4 are opened on the top of the grate plate body 1, an air inlet 5 is opened in the middle part of the bottom of the grate plate body 1, pressure relief ports 6 are opened on both sides of the front of the grate plate body 1, a plurality of positioning holes 7 are opened on the bottom of the left and right sides of the grate plate body 1, a fixing pipe 8 is fixedly installed inside the cavity 2, and limiting flow plates 9 are fixedly installed on both sides of the top of the grate plate body 1.
[0024] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 Through the structural design of the cavity 2, the diffusion bucket 3, the vertical hole 4, the air inlet 5, and the pressure relief port 6, and through the mutual cooperation between the structures, the function of rapid flow of cooling gas is realized, and the problem of low heat exchange efficiency is solved. The introduced cooling gas is completely released to achieve the purpose of high-speed flow of gas, so that the cooling gas is quickly delivered to the surface of the medium to be cooled, so that the medium to be cooled is quickly cooled, thereby improving the cooling efficiency, reducing the production time, efficiently utilizing the cooling medium, reducing the energy consumption of the cooling system, and improving the production efficiency. Through the setting of the positioning hole 7, the grate plate body 1 is fixed on the grate cooler working position in coordination with the positioning pin. The function of the area can maintain the stability of the grate body 1 during operation, thereby reducing the blockage of the medium to be cooled on the top of the grate body 1, which in turn causes the grate cooler to be unable to operate normally. The setting of the fixed pipe 8 realizes the function of protecting the positioning pin, thereby cooperating with the diffusion bucket 3 to isolate the positioning pin from the high-temperature gas, thereby extending the service life of the positioning pin, thereby reducing the failure rate of the grate cooler. The setting of the limiting plate 9 facilitates the limiting of the cooling gas, thereby accurately controlling the cooling range of the cooling gas, avoiding the loss of cooling gas in useless areas, reducing energy waste, and further increasing the efficiency of heat exchange.
[0025] The top of the grate plate body 1 is inclined at an angle of 10°-13°.
[0026] Reference Figure 1 and Figure 2 The inclination angle can promote the fluidity of the medium to be cooled, reduce the risk of accumulation and blockage of the medium to be cooled on the grate plate body 1, and enable the cooling gas to better exchange heat with the material.
[0027] The bottom of the diffusion hopper 3 is connected to the air inlet 5 , and the top of the diffusion hopper 3 is at the bottom of the pressure relief port 6 .
[0028] Reference Figure 2 and Figure 3 The connection between the diffusion hopper 3 and the air inlet 5 can prevent the cooling gas from leaking during the transfer, which would affect the transfer speed of the cooling gas. It also prevents the cooling gas from causing a cyclone inside the cavity 2 to reduce the gas flow speed.
[0029] The vertical holes 4 are divided into multiple rows, and the vertical holes 4 in each row are staggered with the vertical holes 4 on both sides.
[0030] Reference Figure 1 By staggering the vertical holes 4, the medium to be cooled can be fully in contact with the cooling gas, so that heat exchange can be completed more quickly and the purpose of rapid cooling can be achieved.
[0031] The pressure relief ports 6 are arranged side by side in a horizontal position, and the pressure relief ports 6 penetrate the grate plate body 1 .
[0032] Reference Figure 1 and Figure 3 By opening the pressure relief ports 6 side by side, the fluidity of the cooling gas can be maintained, so that the flowing gas can be released quickly, thereby preventing the cooling gas from staying inside the grate plate and causing obstruction to the subsequent cooling gas. By setting up the grate plate body 1, it is convenient to increase the pressure relief efficiency, thereby achieving timely release of excessive gas, avoiding the situation where the cooling gas flow rate is too large or too small, and maintaining stable flow performance.
[0033] The positioning hole 7 is opened in a horizontal position, passes through the grate plate body 1, and is a square hole.
[0034] Reference Figure 1 and Figure 4 By opening the positioning hole 7 horizontally, the grate plate body 1 can be horizontally installed in the working area of the grate cooler, so as to better match the tilt angle and achieve the purpose of the flow of the medium to be cooled.
[0035] The length of the flow limiting plate 9 is slightly shorter than the length of the grate plate body 1 , and a chamfer is provided on one side of the bottom of the flow limiting plate 9 .
[0036] Reference Figure 1By setting the flow limiting plate 9 to be lower than the length of the grate plate body 1, it is convenient to install the device array in the working area of the grate cooler to avoid mutual interference between adjacent grate plates.
[0037] Working principle: When using this device, the diffusion hopper 3 is carried by the cavity 2, the positioning pin is installed through the positioning hole 7, the grate plate body 1 is connected to the grate cooler through the positioning pin, the positioning pin is protected by the fixing tube 8, the object to be cooled is carried by the grate plate body 1, the cooling gas is introduced through the air inlet 5, the cooling gas is released to the vertical hole 4 through the diffusion hopper 3, the cooled object rolls through the inclined surface of the grate plate body 1, the cooling gas contacts the cooled object through the vertical hole 4, the cooled object blocks the vertical hole 4 when rolling, the excess gas is released from the grate plate body 1 through the pressure relief port 6, and the cooling gas is limited by the flow limiting plate 9.
[0038] The above shows and describes the basic principle, main features and advantages of the utility model.
