Description

Technical Field

[0001] The utility model belongs to the technical field of soil remediation equipment, and particularly relates to an anti-blocking curing agent injection pipe. Background Art

[0002] In the process of fixing the sludge, the sludge and the solidifying agent need to be fully mixed. During the mixing process, the rotary stirring device can effectively stir it, thereby fully mixing the solidifying agent and the sludge. When the solidifying agent is transported, an injection pipe is required to continuously transport the solidifying agent.

[0003] When the current curing agent injection pipe is in use, it needs to be extended into the sludge along with the stirring device. When the curing agent injection stops, the pipe cannot be automatically sealed. The sludge entering the pipe is easy to dry and cause pipe blockage. At the same time, it is impossible to discharge the residual sludge, which affects the subsequent curing agent delivery. For this reason, we propose an anti-blocking curing agent injection pipe.

[0029] See also Figure 1-Figure 5 The utility model provides a technical solution: an anti-blocking curing agent injection pipe, comprising a main injection pipe 3, with auxiliary injection pipes 2 arranged obliquely on both sides of the main injection pipe 3. By setting the auxiliary injection pipes 2 on both sides, the curing agent can be transported to both sides, thereby improving the transport efficiency of the curing agent. Anti-blocking structures 1 are arranged on the auxiliary injection pipes 2;

The valve plate assembly includes a first valve plate 104, and the first valve plate 104 is arranged on the first rotating shaft 103. The first rotating shaft 103 is rotatably arranged in the mounting seat 102. A winding wheel 101 is also arranged on one side of the first rotating shaft 103, and a pull rope 106 is arranged on the winding wheel 101. One end of the pull rope 106 is connected to the rack 107, and the rack 107 is movably arranged in a cavity 114. The cavity 114 is arranged on one side of the auxiliary injection pipe 2, and a reset spring 113 is arranged on one side surface of the cavity 114. One end of the reset spring 113 is connected to the rack 107, which can provide tension for the movement of the rack 107 and make the rack 107 automatically reset.

[0031] During the curing agent delivery process, the curing agent is delivered to the auxiliary injection pipe 2 through the main injection pipe 3. Under the action of pressure, the curing agent drives the two groups of first valve plates 104 to unfold, and the first valve plates 104 drive the first rotating shaft 103 to rotate. The rotation of the first rotating shaft 103 drives the winding wheel 101 to rotate, and the winding wheel 101 rotates to reel in the pull rope 106. During the reeling process of the pull rope 106, the rack 107 is pulled to move, and the rack 107 moves to stretch the reset spring 113. When the curing agent stops being injected, the reset spring 113 drives the rack 107 to reset and move, and then drives the pull rope 106 to move. The pull rope 106 drives the winding wheel 101 to rotate, and the winding wheel 101 drives the first rotating shaft 103 to rotate. The first rotating shaft 103 drives the two groups of first valve plates 104 to rotate, and then the two groups of first valve plates 104 seal the auxiliary injection pipe 2.

[0032] Furthermore, a sleeve 108 is provided on the other side surface of the rack 107, a pull rope 106 is provided in the sleeve 108, the sleeve 108 is movably provided in the guide sleeve 111, and the guide sleeve 111 is provided on the other side surface of the cavity 114. When the pull rope 106 is wound, it drives the rack 107 to move, and the rack 107 drives the sleeve 108 to move in the guide sleeve 111, which can guide the movement of the rack 107 and prevent the rack 107 from moving offset.

[0033] Furthermore, limit sliders 110 are symmetrically arranged on both sides of the outer surface of the sleeve 108, and one end of the limit slider 110 is slidably arranged in the limit slot 109. The limit slot 109 is symmetrically arranged on both sides of the inner wall of the guide sleeve 111. When the sleeve 108 moves, the sleeve 108 drives the limit slider 110 to move in the limit slot 109, which can position the movement of the sleeve 108 and improve the stability of the sleeve 108 when moving.

The transmission gear 116 is engaged with the rack 107, which can drive the second rotating shaft 115 to rotate and make the second rotating shaft 115 rotate in the opposite direction to the first rotating shaft 103. A connecting frame 117 is also provided on the second rotating shaft 115, and a second valve plate 105 is provided at one end of the connecting frame 117.

[0035] When the first valve plate 104 is unfolded, the movement of the rack 107 drives the transmission gear 116 to rotate, the rotation of the transmission gear 116 drives the second rotating shaft 115 to rotate, the rotation of the second rotating shaft 115 drives the connecting frame 117 to rotate, the rotation of the connecting frame 117 drives the second valve plate 105 to rotate, and the two groups of second valve plates 105 are unfolded. When the rack 107 is reset and moved, the transmission gear 116 drives the second rotating shaft 115 to rotate, the second rotating shaft 115 drives the connecting frame 117 to rotate, and the connecting frame 117 drives the second valve plate 105 to rotate. Through the rotation of the second valve plate 105, the sludge remaining in the auxiliary injection pipe 2 is automatically pushed out.

[0036] Furthermore, the connecting frame 117 is movably arranged in the regulating port 112 . The regulating port 112 is arranged on one side of the inner wall of the auxiliary injection pipe 2 , and the regulating port 112 is communicated with the cavity 114 .
