[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] A quick-release heating chamber gas distribution plate, such as Figure 1 , Figure 2 As shown, it includes:

[0025] Heating chamber 1 is a cylindrical structure with an open bottom. It contains a heater and is equipped with a sealing cover at the bottom. Heating chamber 1 moves up and down above the sealing cover by a lifting device. An air supply pipe 3 is provided at the top of heating chamber 1, and the bottom of the air supply pipe 3 passes through the top wall of heating chamber 1 for a certain distance. The outer wall of the bottom of the air supply pipe 3 is provided with a threaded structure. A ring-shaped clamping plate 11 is provided around the inner wall, and a pair of vertical positioning grooves 14 are provided on the inner wall. Two sealing ring grooves 9 are provided on the bottom surface of the clamping plate 11.

[0026] The gas distribution plate 2 and its usage are existing, mature technologies familiar to the general public, and as... Figure 2As shown, after being arranged horizontally, it is fitted inside the assembly pipe 4 and welded to one end of the assembly pipe 4. A filter plate 7 (removable) is installed inside the other end of the assembly pipe 4, and a ring-shaped assembly plate 10 is provided on the outer wall of the other end along the circumference. The assembly plate 10 is movably fitted with the air supply pipe 3. A positioning slider 12 is provided on the outer wall corresponding to the positioning groove 14, and two sealing gaskets 8 are provided at the top and bottom respectively (the sealing gaskets 8 are correspondingly provided with the sealing ring groove 9 of the clamping plate 11). The assembly pipe 4 is installed in the air supply pipe 3 through a quick disassembly and assembly structure.

[0027] Quick-assembly structure such as Figure 3 , Figure 4 As shown, it includes an abutting sleeve 5 and an annular cap 6. The abutting sleeve 5 is movably fitted inside the air supply pipe 3, and a positioning slider 13 is provided on the outer wall and is slidably set in the positioning groove 14. A sealing ring groove 9 is provided on the top corresponding to the sealing gasket 8. The annular cap 6 is an annular structure with a U-shaped cross section, and its inner wall is rotatably set inside the air supply pipe 3. Its top abuts against the bottom of the abutting sleeve 5, and its outer wall is threaded together with the bottom of the air supply pipe 3. An anti-slip groove is provided on the outer side of the outer wall to prevent slippage.

[0029] The assembly pipe 4, with the gas distribution plate 2 fixed thereon, is placed into the air supply pipe 3, and its positioning slider 12 is slidably engaged in the corresponding positioning groove 14. Then, the abutment sleeve 5 is slidably engaged in the air supply pipe 3 (positioning slider 2 13 is slidably engaged in the positioning groove 14). The annular cap 6 is placed on the bottom of the air supply pipe 3 and rotated, so that the annular cap 6 moves upward under the action of the thread and squeezes the abutment sleeve 5 from below. The assembly plate 10 is clamped between the abutment sleeve 5 and the clamping plate 11, and the sealing gasket 8 is inserted into the corresponding sealing ring groove 9 and abuts against the bottom of the corresponding sealing ring groove 9 to form a seal. Continue to rotate the annular cap 6 until the upper and lower sides of the assembly plate 10 abut against the abutment sleeve 5 and the clamping plate 11 respectively.

[0030] Air is supplied to the heating chamber 1. After the gas is filtered by the filter plate 7, the velocity and dynamic pressure decrease, which facilitates the gas distribution plate 2 to evenly distribute the gas, regulate the flow rate, and control the path.
