DETAILED DESCRIPTION

[0022] In order to make the utility model purposes, technical solutions and advantages more clearly, the following will be further described in detail with the help of the drawings and examples.

[0023] The specific implementation of the utility model will be described in detail in combination with specific examples.

[0024] Please refer to Figures 1 to 4 The utility model discloses a preparation device for water purifying agent, which comprises a stirring kettle 1, an inner container cylinder 3 and a piston disc 5.

[0025] In the embodiment of the utility model, please refer to Figures 1 to 4 The top of the stirring kettle 1 is fixedly provided with a feeding hopper 11, and a liquid discharge pipe 12 is also arranged on the stirring kettle 1; a rotating shaft 2 is rotatably arranged in the stirring kettle 1; a servo motor 8 is fixedly arranged on the stirring kettle 1 through a rack; the output end of the servo motor 8 is fixedly connected with the connecting end of the rotating shaft 2; the rotating shaft 2 is sleeved with the rotatably arranged inner container cylinder 3; two symmetrical lifting rods 9 are fixedly arranged on the top of the inner container cylinder 3; the two lifting rods 9 are both fixedly arranged on the inner top wall of the stirring kettle 1, so that the fixing of the inner container cylinder 3 is realized; a reciprocating threaded part 21 is arranged on the rotating shaft 2 in the inner container cylinder 3; the piston disc 5 is threadedly connected with the reciprocating threaded part 21; two symmetrical limiting rods 6 are fixedly arranged on the inner top wall of the inner container cylinder 3; the two limiting rods 6 are respectively arranged through the through holes of the piston disc 5 and are slidably connected with the through holes; an expanding part 31 is arranged at the bottom of the inner container cylinder 3; a plurality of annularly arranged side flow ports 31a are arranged on the expanding part 31; an overhanging arc surface 32 is arranged at the top of the inner container cylinder 3; a plurality of annularly arranged liquid discharge holes 32a are arranged on the overhanging arc surface 32.

[0026] The bottom of the rotating shaft 2 extends out of the barrel opening at the bottom of the inner container cylinder 3 and is fixedly sleeved with the stirring blade 4; the outer barrel wall of the inner container cylinder 3 is fixedly sleeved with the helical blade 7.

[0027] It should be noted that: by feeding hopper 11 to the inside of the stirred tank 1 to add raw materials of water purifying agent, open the servo motor 8 to drive the rotating shaft 2 to rotate, so that the stirring blade 4 can fully stir and mix the raw materials of the water purifying agent. Because the piston disc 5 threaded with the reciprocating screw part 21 is limited by the limiting rod 6, the piston disc 5 can be lifted along the inner cylinder 3. When the piston disc 5 rises along the inner cylinder 3, the inner cylinder 3 forms a negative pressure, so that the liquid at the bottom of the stirred tank 1 can flow into the inner cylinder 3 below the piston disc 5. At this time, the liquid in the inner cylinder 3 above the piston disc 5 is discharged from the inner cylinder 3 through the drain hole 32a. When the piston disc 5 descends along the inner cylinder 3, the liquid in the inner cylinder 3 below the piston disc 5 is discharged. At this time, the liquid in the cavity between the stirred tank 1 and the inner cylinder 3 flows into the inner cylinder 3 above the piston disc 5 through the drain hole 32a.

[0028] Therefore, the rotating shaft 2 drives the stirring blade 4 to perform basic stirring on the material in the stirred tank 1, and the reciprocating screw part 21 drives the piston disc 5 to ascend and descend along the inner cylinder 3, forming forced material circulation inside and outside the inner cylinder 3.

[0029] Wherein, the liquid height in the cavity between the stirred tank 1 and the inner cylinder 3 is raised after the piston disc 5 descends to the lowest point. Because the outer cylinder wall of the inner cylinder 3 is fixedly sleeved with the spiral blade 7, the material flows along the spiral path during the rising process, further breaking the material layering and achieving global mixing, effectively solving the problem of insufficient local mixing of the traditional device.

[0030] It should be further noted that: when the piston disc 5 ascends and descends along the reciprocating screw part 21, a pumping effect can be formed, that is, the bottom flared part 31 side flow port 31a and the bottom cylinder port suction sediment material, reducing the risk of particle material deposition at the bottom of the stirred tank 1, greatly improving the uniformity of the reaction.

[0031] Further, the outer ring wall of the piston disc 5 is sleeved with a rubber sleeve, and the rubber sleeve abuts against the inner cylinder wall of the inner cylinder 3. A rubber ring is inserted into the through hole of the piston disc 5, and the rubber ring in the through hole is in sealing cooperation with the limiting rod 6, which effectively reduces material leakage, reduces raw material waste and environmental impact.

[0032] The circuit and control involved in the present application are prior art, and will not be described in detail here.

[0033] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process conversion made by using the contents of the present application specification and drawings, or directly or indirectly applied to other related technical fields, are also included in the patent protection range of the present application.
