[0024] like Figure 1-4 As shown, an embodiment of the utility model proposes a discharging device for producing alkaline cleaning agents, including a reactor 1 with an inner cavity, a top cover 4 is arranged on the top of the reactor 1, the top cover 4 includes a first cover body 41 fixedly connected to the top of the side wall of the reactor 1 and a second cover body 42 rotatably connected to the middle part of the first cover body 41, a discharge port is arranged at the bottom of the reactor 1, the bottom of the discharge port is connected with a mixing pipe 2 arranged in a horizontal direction, the right end of the mixing pipe 2 is connected with a discharge pipe 3, and the left end is internally slidably connected with a piston 26, and a driving mechanism for driving the piston 26 to reciprocate along the length direction of the mixing pipe 2 is arranged on the left side of the mixing pipe 2, a first one-way valve 20 is arranged between the discharge port and the mixing pipe 2, and a second one-way valve 21 is arranged between the mixing pipe 2 and the discharge pipe 3.

[0025] In this embodiment, the bottom of the reactor 1 is conical, which is convenient for discharging. A feed pipe 16 is provided on the top of the side wall of the reactor 1. A feed valve 17 is provided in the feed pipe 16 to facilitate feeding and avoid interference with the stirring mechanism. A discharge valve 18 can also be provided above the first one-way valve 20 in the feed port of the reactor 1 to control the discharge. The feed port is connected to the inside of the material mixing pipe 2 in one way through the first one-way valve 20, and the material mixing pipe 2 is connected to the inside of the discharge pipe 3 in one way through the second one-way valve 21. With such a structural design, when the piston 26 When the piston 26 moves horizontally to the left in the sparging tube 2, a negative pressure is generated in the internal space of the sparging tube 2. At this time, the first one-way valve 20 opens and the second one-way valve 21 closes, so that the alkaline cleaning agent in the reactor 1 can be sucked into the sparging tube 2. When the piston 26 moves horizontally to the right in the sparging tube 2, a stroke is generated in the sparging tube 2. At this time, the first one-way valve 20 closes and the second one-way valve 21 opens, so that the alkaline cleaning agent in the sparging tube 2 can be quantitatively squeezed out from the discharge pipe 3 to achieve quantitative discharge. The first one-way valve 20 and the second one-way valve 21 both include a rubber disc and a support rod. The rubber disc is made of soft black rubber. The support rod is cross-shaped and fixed on one side of the rubber disc. When the alkaline cleaning agent passes through in the forward direction, the pressure causes the rubber disc to bend to the side away from the support rod, and the alkaline cleaning agent can flow through from the circumference. When the pressure stops, the rubber has a certain elasticity and the rubber disc returns to its initial state. When the alkaline cleaning agent passes through in the reverse direction, the rubber does not deform under the action of the cross-shaped support rod, and the alkaline cleaning agent cannot pass through. Such a structural design is simple in structure, easy to use, low in cost, and can achieve the goal of allowing only one-way passage of the fluid.

A support rod 11 is vertically fixed on the top of the first cover 41, and a mounting plate 12 is fixed on the support rod 11. The top of the first motor 9 is fixedly mounted on the bottom of the mounting plate 12 by bolts. A bracket 13 is arranged between the sleeve 10 and the mounting plate 12. The two ends of the bracket 13 are fixedly connected to the bottom of the mounting plate 12 and the top of the sleeve 10, respectively. In this embodiment, multiple brackets 13 can be evenly arranged along the circumference of the sleeve 10, which can support the sleeve 10 while preventing the sleeve 10 from rotating with the driving shaft 5.

The second stirring blade 8 stirs and mixes the raw materials at the inner edge of the reactor 1. The active stirring component and the driven stirring component jointly stir the raw materials fully, so that the stirring and mixing effect is good, the raw materials are mixed evenly, and the raw material mixing efficiency is high.

[0031] The driving mechanism includes a second motor 22, a worm wheel 23, a worm 24, a cam 31 and a piston rod 25.

At the same time, under the action of the power component, the driven shaft 6 revolves while rotating, and the active stirring component and the driven stirring component jointly promote the alkaline cleaning agent in the reactor 1 to mix evenly. After stirring for a certain period of time, the discharge valve 18 is opened, and the second motor 22 is started. The second motor 22 rotates.
