Technical Field

[0001] The utility model relates to the technical field of dustproof mesh plate installation, in particular to a hot air heater which is convenient for disassembling and assembling a dustproof mesh plate. Background Art

[0002] Dust-proof nets, also known as "wind-proof and dust-suppression nets" and "windbreak walls", are an environmental protection project for controlling dust pollution in open-air material yards. They are widely used in industrial facilities such as bulk material ports and fuel yards of thermal power plants.

[0003] Existing dustproof mesh panels are mostly installed by fixing them with screws. To fix the dustproof mesh panels with screws, professional tools are needed to rotate the screws to complete the installation and removal of the screws. When replacing the dustproof mesh panels, all screws need to be removed in turn, and then the screws need to be re-fixed to install the new dustproof mesh panels. This makes it time-consuming to install the dustproof mesh panels with screws, thereby reducing the efficiency of replacing and installing the dustproof mesh panels. Therefore, the present application designs a hot air heater that is easy to disassemble and assemble the dustproof mesh panels to solve the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example: See Figure 1-6 The utility model discloses a hot air heater with a dustproof screen that is easy to disassemble and assemble, comprising a heater box 1, a side end of the heater box 1 is provided with an air inlet pipe 2, a side end of the air inlet pipe 2 is provided with a first mounting groove 4, the first mounting groove 4 is provided with a dustproof screen 3, and the dustproof screen 3 can be better installed and fixed by setting the first mounting groove 4; the side end of the first mounting groove 4 is symmetrically provided with two second mounting grooves 6, each of which is clamped with a locking limit block 8, and the locking limit block 8 is symmetrically provided with two lifting springs 13, through Through the setting of the second mounting groove 6 and the locking limit block 8, the dustproof mesh plate 3 can be better pushed into the abutment groove 9, thereby automatically locking the dustproof mesh plate 3 extended into the first mounting groove 4, thereby improving the convenience of installation of the dustproof mesh plate 3; the upper and lower ends of the first mounting groove 4 are symmetrically provided with limit protrusions 5, and the upper and lower ends of the dustproof mesh plate 3 are symmetrically provided with limit grooves 11 for cooperating with the limit protrusions 5. Through the setting of the limit protrusions 5 and the limit grooves 11, the dustproof mesh plate 3 can be better limited, thereby improving the stability of installation and disassembly of the dustproof mesh plate 3.

[0022] In the present invention, an abutment groove 9 is provided at the side end of the dustproof mesh plate 3, and a limit card groove 10 is symmetrically provided in the abutment groove 9, and a movable abutment block 12 is provided in the limit card groove 10. Through the setting of the movable abutment block 12, the movable abutment block 12 can cooperate with the top block 7 to push the locking limit block 8 out of the abutment groove 9, thereby unlocking the locking limit block 8 to fix the dustproof mesh plate 3; T-shaped limit card blocks 14 are symmetrically provided at the upper and lower ends of the movable abutment block 12, and T-shaped sliding grooves for clamping and limiting with the limit card block 14 are provided at the upper and lower ends of the limit card groove 10.

[0023] Working principle: When the utility model is used, first, during the initial installation, one end of the second chamfer of the dustproof mesh plate 3 is directly pushed into the first installation groove 4. When the dustproof mesh plate 3 is pushed in, the second chamfer pushes open the locking limit block 8, and then the dustproof mesh plate 3 is extended into the first installation groove 4, and the locking limit block 8 pushes open the movable abutment block 12 to clamp the dustproof mesh plate 3. Then, when a new dustproof mesh plate 3 is installed subsequently, the top block 7 is pushed into the abutment groove 9, so that the movable abutment block 12 slides to both sides to push open the locking limit block 8, thereby unlocking the installation and fixation of the original dustproof mesh plate 3, and then continue to push in the new locking limit block 8 until the new dustproof mesh plate 3 is locked and fixed with the locking limit block 8. At this point, the installation of the dustproof mesh plate 3 is completed.
