A forward and reverse motor 105 is fixedly installed on the top of the inner wall of the heating frame 104. A threaded rod 106 is fixedly installed on one side of the outer wall of the forward and reverse motor 105. A concave plate 107 is threadedly connected to the outer wall of the threaded rod 106. The top of the concave plate 107 is fixedly installed.

[0027] The effect achieved by the entire embodiment 1 is that the heating frame 104 is detachably mounted on the two sliding blocks 103, and is movably embedded in the two sliding grooves 102 through the two sliding blocks 103, and requires external force to move, so that the heating frame 104 is conveniently installed at the bottom of the continuous casting outlet pipe 202, and then the forward and reverse motors 105 are started to drive the threaded rod 106 to rotate inside the strip plate 109. Since a limiting rod 111 is installed between the strip plate 109 and the fixed block 110, and the concave plate 107 is movably sleeved on the limiting rod 111, the concave plate 107 can reciprocate on the limiting rod 111 and the threaded rod 106, and the heater 108 can heat multiple areas at the bottom of the continuous casting outlet pipe 202, ensuring that the metal liquid flowing inside will not solidify and will not cause blockage at the continuous casting outlet pipe 202, thereby improving the use effect of the device for preventing continuous casting water nozzle blockage.

[0028] Embodiment 2, as Figure 2-Figure 4 As shown, the filtering mechanism 2 includes two brackets 201, and a continuous casting outlet pipe 202 is fixedly installed between the opposite sides of the outer walls of the two brackets 201, and two perforated blocks 203 are fixedly installed on the outer wall of the continuous casting outlet pipe 202, and one side of the outer wall of the two perforated blocks 203 is provided with a fixing hole 204, and one side of the outer wall of the continuous casting outlet pipe 202 contacts a filter plate 205, and the outer wall of the filter plate 205 is fixedly installed with two plug-in blocks 206, and the outer walls of the two plug-in blocks 206 are movably inserted into the inside of the two perforated blocks 203, the inner walls of the two fixing holes 204 are threadedly connected with fixing bolts 207, and the outer walls of the two fixing bolts 207 are movably inserted into the inside of the two plug-in blocks 206, and the bottoms of the two brackets 201 are fixedly connected to the top of the base plate 101. The effect achieved by the entire embodiment 2 is that, by adding a filter plate 205 at the continuous casting outlet pipe 202, impurities and solid particles in the molten metal can be filtered out, further reducing the risk of blockage. Secondly, two perforated blocks 203 are installed on the outer wall of the continuous casting outlet pipe 202, and then the filter plate 205 is inserted into the two perforated blocks 203 through the plug blocks 206 installed on both sides, and then two fixing bolts 207 pass through the two plug blocks 206 and are threadedly connected in the two perforated blocks 203. The installation process is simple, which is convenient for the staff to disassemble and assemble the filter plate 205, and clean or replace it, thereby improving the filtration efficiency, thereby further improving the use effect of the device for preventing continuous casting water inlet blockage.

[0029] Working principle: First, the heating frame 104 is installed on the two sliding blocks 103 in a detachable manner, and is moved to a suitable position through the two sliding grooves 102. Then, when the molten metal liquid in the casting process flows inside the continuous casting outlet pipe 202, the forward and reverse motors 105 are started to drive the concave plate 107 to move on the threaded rod 106. Since the concave plate 107 is movably sleeved on the limit rod 111, the concave plate 107 can reciprocate on the threaded rod 106 and the limit rod 111, so that the heater 108 installed on the top of the concave plate 107 can heat multiple areas at the bottom of the continuous casting outlet pipe 202, so as to control the pouring temperature of the metal liquid and avoid the molten metal liquid Solidification occurs, and secondly, a filter plate 205 is installed on one side of the outer wall of the continuous casting outlet pipe 202 to filter out impurities and solid particles, further reducing the risk of clogging, and the filter plate 205 is inserted into two perforated blocks 203 through two plug blocks 206, and then installed on one side of the continuous casting outlet pipe 202 through two fixing bolts 207, and the installation process is simple, which makes it easy to disassemble and assemble the filter plate 205 and replace or clean it. In general, through the action of the temperature control mechanism 1 and the filtering mechanism 2, the quality of the continuous casting nozzle casting is improved, and the risk of continuous casting nozzle clogging is reduced, thereby improving the use effect of the device for preventing continuous casting nozzle clogging.
