DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 to Figure 5 In the embodiment of the utility model, a high-efficiency reactor for producing concrete additives includes a reactor body 1 and a jacket 2 formed on the outer wall of the reactor body 1, an interlayer 6 is provided between the reactor body 1 and the jacket 2, a discharge port 3 penetrating to the bottom of the jacket 2 is provided at the center of the bottom end of the reactor body 1, a valve mechanism is provided inside the discharge port 3, and a power mechanism for driving the valve mechanism to operate is provided on the discharge port 3;

[0030] The valve mechanism includes a sliding valve 10, which is a hollow structure with upper and lower openings. The sliding valve 10 is connected to the inner cavity of the discharge port 3 by sliding up and down.

[0031] The sliding valve 10 that moves upward once is used to discharge the material inside the kettle body 1, the sliding valve 10 that moves upward twice is used to discharge the condensed water inside the interlayer 6, and the sliding valve 10 that is reset downward to the initial position is used to close the discharge port 3 to prohibit the discharge of condensed water and material;

[0032] The power mechanism is used to drive the sliding valve 10 in the valve mechanism to move up and down.

[0033] In this embodiment, when the power drives the valve mechanism to move, specifically: the valve mechanism is driven to move upward once, and at this time, the power mechanism drives the sliding valve 10 to move upward once, so that the material inside the kettle body 1 is discharged (see Figure 5 (b)), after the material is completely discharged, the sliding valve 10 is driven by the power mechanism to move upward once again (i.e., the second displacement), and the sliding valve 10 blocks the discharge of the kettle body 1, and the condensed water inside the interlayer 6 is discharged through the water hole 11 (see Figure 5 In (c), the discharged condensed water is discharged to the outside through the discharge port 3;

[0034] After the condensed water is discharged, the power mechanism runs in the reverse direction, driving the sliding valve 10 to reset, and the outlet of the condensed water and the outlet of the valve body 1 are blocked, thereby achieving a sealing effect and facilitating the normal operation of the reactor.

[0035] Please refer to Figure 2 and Figure 3 The valve mechanism further includes: two fixed heads 7, the bottom ends of the two fixed heads 7 are integrally formed with a connecting plate 8 fixedly connected to the inner wall of the discharge port 3, and a plurality of leakage holes 9 arranged equidistantly are opened in the inner circumference of the connecting plate 8;

[0036] The top ends of the two fixed heads 7 are both in a cone-shaped structure, and the outer circumference of the fixed heads 7 is smaller than the inner circumference of the discharge port 3, and the sliding valve 10 is located between the two connecting plates 8;

[0039] And the end of the water hole 11 located inside the discharge port 3 is a downwardly inclined end.

[0040] In this embodiment: when the power mechanism drives the sliding valve 10 to move upward once, the inner periphery of the sliding valve 10 and the outer wall of the fixed head 7 located below change from the overlapping state to the separated state, and the sliding valve 10 also blocks the water hole 11 at this time. At this time, the material located in the kettle body 1 moves downward from the inner cavity of the sliding valve 10, and flows into the discharge port 3 from the leakage hole 9 through the gap between the sliding valve 10 and the fixed head 7, and is discharged from the discharge port 3;

[0041] When the material is completely discharged, the power mechanism is started again, and the power mechanism drives the sliding valve 10 to move upward again until the top of the sliding valve 10 is completely in contact with the bottom of the connecting plate 8 located above, until the upper inclined surface 20 is completely in contact with the lower inclined surface 21, and the sliding valve 10 blocks the leakage hole 9 located above, and at the same time cancels the blocking of the water hole 11, then the condensed water in the interlayer 6 flows into the discharge port 3 from the water hole 11, and is discharged from the discharge port 3, so that when the kettle body 1 is running again, the heat energy loss caused by the condensed water is reduced, and the high efficiency of the operation of the kettle body 1 is ensured;

[0042] When the condensed water is completely discharged, the sliding valve 10 is driven downward again by the power mechanism until the sliding valve 10 is completely downward. At this time, the inner cavity wall of the sliding valve 10 is in contact with the outer wall of the fixed head 7 located below, and the water hole 11 is effectively blocked, completing the closure of the kettle body 1, which is convenient for the normal operation of the kettle body.
