Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanized steel plate processing, in particular to hot-dip galvanized steel plate processing preheating recovery equipment. Background Art

[0002] After the steel plate is galvanized, a galvanized layer will be formed on the surface, of which the outermost layer is a free zinc layer. Under the premise of ensuring good cooling treatment, the glossiness of the coating surface is positively correlated with the glossiness of the modulated zinc liquid. If the steel plate is not cooled in time after galvanizing, even if the modulated zinc liquid is very bright, it is impossible to obtain a coating surface with good gloss. Therefore, the steel plate needs to be cooled immediately after galvanizing, and a large amount of heat will be generated during cooling.

[0003] After hot-dip plating of steel plates, the processed steel plates need to be placed in a cooling pool for cooling. During cooling, a lot of hot air with high heat content will be generated. The current processing equipment does not recycle the generated hot air, but directly discharges the hot air into the air, which will cause a waste of heat energy. Moreover, a large amount of hot air discharged into the air will cause a large amount of water vapor in the air. According to the temperature change, the water vapor will turn into water droplets, which will cause the indoor environment to become very humid. If it is in a humid environment for a long time, it may cause damage to the surface of the indoor instruments. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] like Figure 1-3 As shown, a hot-dip galvanized steel plate processing preheating recovery equipment includes a cooling pool 1 and a recovery component 2.

[0025] The recovery component 2 includes a collection plate 201, a first transmission pipe 202, a telescopic pipe 203, a second transmission pipe 204, a smoking machine 205 and a short pipe 206. The first transmission pipe 202 is fixedly connected to the left side of the collection plate 201, and the telescopic pipe 203 is fixedly connected to one side of the first transmission pipe 202. The telescopic pipe 203 is for facilitating the up and down movement of the collection plate 201. The second transmission pipe 204 is fixedly connected below the telescopic pipe 203, and a placement groove is provided at the corresponding position of the cooling pool 1 and the second transmission pipe 204. The end of the second transmission pipe 204 away from the telescopic pipe 203 is fixedly connected to the smoking machine 205, and the short pipe 206 is fixedly connected below the smoking machine 205.

[0026] The specific operation is as follows: start the smoke extractor 205 to collect the hot air generated in the cooling pool 1 into the first transmission pipe 202 through the collection plate 201, and then transmit it to the smoke extractor 205 through the telescopic pipe 203 and the second transmission pipe 204, and then flow into the waste heat processor 3 through the short pipe 206 for energy conversion. By setting up the recovery component 2, the generated hot air can be collected through the collection plate 201, and then the thermal energy inside the hot air can be converted into electrical energy through the waste heat processor 3, and then reasonably utilized, thereby avoiding directly discharging the hot air into the air, which will cause waste of heat energy, and thus can increase its own practicality.

[0027] The waste heat processor 3 is an ORC waste heat generator. The ORC waste heat power generation system consists of a magnetic levitation turbine expander, a high-efficiency evaporator, a condenser, a working fluid pump and a distribution box. It converts the heat energy in waste steam, waste hot liquid and waste flue gas into electrical energy through the organic Rankine cycle principle.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, a lifting assembly 4 for adjusting the height of the collecting plate 201 is provided on one side of the collecting plate 201, and the lifting assembly 4 includes a lifting base 401 and a slider 402. The slider 402 is provided inside the lifting base 401, and the lifting base 401 is fixedly connected to the cooling pool 1. A sliding groove is provided at the corresponding positions of the lifting base 401 and the slider 402. The lifting assembly 4 also includes a columnar rod 403 and a screw rod 404. The slider 402 is fixedly connected to the columnar rod 403 on one side close to the collecting plate 201. The columnar rod 403 is used to connect the collecting plate 201 with the slider 402. The slider 402 is internally threaded with the screw rod 404.

A support plate 6 is placed below the motor 5, and the support plate 6 is fixedly connected to the cooling pool 1.

[0030] The specific operation is as follows. When the height needs to be adjusted, start the motor 5 to rotate the screw rod 404 inside the lifting base 401, so that the slider 402 moves on the screw rod 404, thereby driving the collecting plate 201 to move up and down. By installing the lifting base 401, the height of the collecting plate 201 can be adjusted to prevent the liquid from entering the device through the collecting plate 201 when placing heavier parts, thereby affecting the use of the device.

When the height needs to be adjusted, start the motor 5 to rotate the screw rod 404 inside the lifting base 401, so that the slider 402 moves on the screw rod 404, thereby driving the collecting plate 201 to move up and down. This is the working principle of the hot-dip galvanized steel plate processing preheating recovery equipment.
