The mixing motor 17 drives the stirring rod 18 and the stirring blade to rotate, and the raw materials and the foaming aid are mixed. Then the mixing motor 17 is turned off, and one end of the air blowing pipe 16 is connected to the pipeline containing high-pressure gas. The high-pressure gas is blown into the bottom of the foaming tank 1 through the air blowing pipe 16 to form foam. At the same time, the submersible pump 2 is started, and the foam is pumped into the foam nozzle 4 through the submersible pump 2 and the discharge pipe 3 to complete the feeding. After the foam spraying is completed, the remaining liquid in the foaming tank 1 is discharged through the sewage pipe 14. The air blowing pipe 16, the exhaust pipe 15, the sewage pipe 14, the dosing pipe 13, the feed pipe 12 and the discharge pipe 3 are all provided with electric valves.

[0038] like Figure 3 to Figure 5 As shown, the fixing assembly 5 includes a connecting ring 501 and a rotation-assisting assembly 6. The connecting ring 501 is arranged at the end of the discharge pipe 3. A positioning groove 502 penetrating along the axial direction is provided on the outer circumferential surface of the connecting ring 501. Four positioning grooves 502 are evenly distributed along the circumferential direction. An arc groove 503 extending along the circumferential direction is provided on the inner wall of one side of the four positioning grooves 502. A clamping block 504 is slidably matched in the four arc grooves 503. An arc spring 505 is provided between the four clamping blocks 504 and the corresponding arc grooves 503. The arc spring 505 will stretch and push the clamping block 504 to extend into the positioning groove 502.

[0039] The rotation-assisting assembly 6 can be relatively rotatably matched with the connecting ring 501. The connecting ring 501 has a guide groove 507 that intersects with the arc groove 503. The guide groove 507 extends in an arc shape along the circumferential direction. Figure 7 As shown; the block 504 is connected to the rotation-assisting assembly 6 through the guide groove 507;

[0040] A positioning block 8 corresponding to the positioning groove 502 is axially protrudingly provided at the top of the foam nozzle 4.

When the positioning block 8 is matched with the positioning groove 502, the slot 9 is opposite to the arc groove 503 in the circumferential direction of the foam nozzle 4.

[0041] Since the arc groove is located on one side of the circumference of the positioning groove and is matched with a clamping block, an arc spring is provided at one end of the clamping block away from the positioning groove, so that the clamping block can extend from the arc groove into the positioning groove. In addition, the clamping block is connected to the rotation-assisting assembly through the guide groove. By rotating the rotation-assisting assembly relative to the connecting ring, the clamping block can be driven to overcome the elastic force of the arc spring and receive the clamping block into the arc groove, so as to facilitate the axial insertion of the positioning block on the foam nozzle into the positioning groove. At this time, the rotation-assisting assembly is released, and the clamping block extends out under the action of the arc spring and is clamped into the matching clamping groove, locking the positioning block in the positioning groove, and completing the rapid installation of the foam nozzle. When disassembling, it is only necessary to rotate the rotation-assisting assembly to retract the clamping block into the arc groove, and then the positioning block can be pulled out from the positioning groove, which is convenient for disassembly.

[0042] The guide groove 507 is located at one end of the connecting ring 501. The block 504 is provided with a booster rod 508 arranged along the axial direction of the connecting ring 501. The booster rod 508 can relatively slide through the guide groove 507 and is connected to the rotation-assisting assembly 6. When the arc spring 505 is extended and the positioning block 8 is separated from the positioning groove 502, the guide groove 507 abuts against the booster rod 508 to prevent the block 504 from being separated from the arc groove 503.

[0043] like Figure 3 As shown, a sealing groove 506 is formed at one end of the connecting ring 501 away from the discharge pipe 3, and an annular groove 10 is formed at one end of the foam nozzle 4 facing the connecting ring 501, and a sealing ring 11 is provided in the annular groove 10 to match the sealing groove 506. In specific implementation, one of the annular groove 10 and the sealing groove 506 can be optionally provided, and the sealing ring 11 can be matched therein to achieve sealing.

[0044] The rotation-assisting assembly 6 includes a transmission ring 601, on which a connecting hole matching the booster rod 508 is axially provided. The transmission ring 601 can be relatively slidably installed at the end of the connecting ring 501, and the booster rod 508 is inserted into the corresponding connecting hole; the transmission ring 601 has a handle 602 protruding radially.

[0045] In this embodiment, in order to prevent the rotation-assisting component 6 from being misoperated, a limit component 7 is also provided. Figure 5 and Figure 6 As shown, the limiting assembly 7 includes a connecting seat 701 which is radially protrudingly arranged on the connecting ring 501, and the connecting seat 701 has a groove 702 which is radially inwardly penetrated, and the groove 702 can slidably cooperate with a limiting member, and the outer circumferential surface of the transmission ring 601 has a limiting groove 603 which matches the limiting member, and a radially arranged return spring 705 is provided between the limiting member and the groove 702, so that the limiting member can be stuck in the limiting groove 603. Specifically, the groove 702 penetrates upward along the axial direction of the connecting ring 501, and the limiting member is a T-shaped plate 704 arranged in the groove 702. The T-shaped plate 704 includes a limiting plate arranged at the top of the groove 702 and a baffle plate arranged vertically in a T shape at the bottom of the limiting plate. The reset spring 705 is located between the baffle plate and the groove 702. The groove 702 has a sliding rod 703 arranged along the radial direction of the connecting ring 501, and the baffle plate has a sliding hole that matches the sliding rod 703 and is slidably mounted on the sliding rod 703; the reset spring 705 is mounted on the sliding rod 703; and the surface of the limiting plate is provided with anti-slip grooves.

[0046] When in use, in order to inspect and replace the foam nozzle 4, the foam nozzle 4 needs to be disassembled. First, the T-plate 704 is pulled, and the T-plate 704 will compress the return spring 705 until the T-plate 704 is separated from the limit groove 603. Then, the handle 602 is held and the handle 602 is rotated a certain angle with the center of the circle of the connecting ring 501 as the center. The handle 602 drives the transmission ring 601 to rotate a certain angle. The transmission ring 601 drives the four blocks 504 to move through the four booster rods 508, so that the four blocks 504 are separated from the four slots 9, and the four blocks 504 are released from the fixation of the four positioning blocks 8. Finally, the foam nozzle 4 is pulled downward, and the foam nozzle 4 drives the four positioning blocks 8 to move downward. The four positioning blocks 8 will be separated from the four positioning slots 502, so that the foam nozzle 4 is removed. When disassembling the foam nozzle 4, there is no need to use a screwdriver to screw multiple screws, which is more convenient.

[0047] It should be added that the four booster rods 508 are driven to move by the handle 602 and the transmission ring 601, and the four booster rods 508 slide along the inner walls of the four guide grooves 507, and the four booster rods 508 drive the four clamping blocks 504 to move, so that the four clamping blocks 504 are retracted into the four arc-shaped grooves 503. The rotation-assisting assembly 6 can simultaneously release the fixation of the four clamping blocks 504 on the foam nozzle 4, without the need to push the four booster rods 508 in sequence, thereby improving the disassembly efficiency.

[0048] When installing the foam nozzle 4, the four arc springs 505 extend and push the four clamping blocks 504 to move, and the four clamping blocks 504 are inserted into the four clamping grooves 9 to complete the fixation of the four positioning blocks 8 and the foam nozzle 4. At this time, the reset spring 705 extends and pushes the T-shaped plate 704, and the T-shaped plate 704 is inserted into the limiting groove 603 to prevent the transmission ring 601 from rotating, thereby consolidating the fixing effect of the clamping block 504 on the positioning block 8 and the foam nozzle 4.
