Description

Technical Field

[0001] The invention relates to the technical field of pure pulp mixers, in particular to a pure pulp mixer for synthesizing a polycarboxylate water-reducing agent. Background Art

[0002] The slurry mixer mixes solids and liquids as specified in the standards and stirs them into a uniform slurry for testing. It is one of the necessary and indispensable equipment for cement plants, construction units, relevant professional colleges and scientific research institutions' cement laboratories. The liquid includes polycarboxylate water reducer.

[0003] By pulling the handle, the slide moves the mixing pot up and down along the guide rails of the column. Once raised to its proper position, tighten the set screws to initiate mixing. Removing the mixing pot causes the opposite action. During mixing, the motor drive mechanism within the slurry mixer body simultaneously drives the impeller shaft on the eccentric seat in orbital motion and rotational motion, which in turn drives the impellers at its base to move synchronously. Specifically, the dual-speed motor transmits power through a coupling to the worm in the transmission case, which then transmits it through a worm gear and a pair of gears to the main shaft, where it is reduced in speed. The main shaft simultaneously rotates the eccentric seat, causing the impellers attached to the seat to orbit, while the impellers rotate around a fixed internal gear via a planetary gear on the impeller shaft's upper end. The dual-speed motor's rotation timing and direction are controlled according to the controller's specified operating procedures.

[0004] However, in the existing slurry mixer for synthesizing polycarboxylic acid water-reducing agent, after the mixing blades have finished mixing the cement and water in the mixing pot, the mixing blades need to be disassembled before the mixing pot can be removed from the mixer due to the large size of the mixing pot, which makes the operation cumbersome. Alternatively, the mixing pot needs to be tilted at a large angle to be removed from or put into the mixer, which may cause material leakage. Moreover, if additional material needs to be added to the mixing pot during the mixing process, the machine needs to be stopped for addition. If the machine is not stopped for addition, part of the additional material will fall on the top of the mixing blades during the addition process, and the rapidly rotating mixing blades will cause the material to splash outward, resulting in an inaccurate proportion of the materials in the mixing pot.

The bottom of the upper stirring shaft 2 is rotatably connected to the lower stirring shaft 21 through a rotating shaft 1. The center of the bottom end of the lower stirring shaft 21 is fixedly provided with a central shaft 22.

The inclined surface 1 203 of the stirring blade 1 23, the inclined surface 204 of the stirring blade 2 24 and the sleeve 25 form a positioning groove 26. When the angle between the inclined surface 1 203 and the inclined surface 204 is greater than ninety degrees, the stirring blade 1 23 and the stirring blade 2 24 are in working condition for stirring. When the angle between the inclined plane 1 203 and the inclined plane 2 204 is less than ninety degrees, the stirring blade 1 23 and the stirring blade 2 24 are in a folded state, which is used to take or place the stirring pot 7.

The connection between the stirring blade 2 24 and the stirring blade 1 23 loses the support of the positioning block 31. At this time, the end of the left baffle 32 away from the positioning block 31 is called the end face 1. A gap is generated between the end face 1 and the stirring blade 2 24, leaving space for the stirring part 3 to rotate, and the side opening 27 on the left side of the lower stirring shaft 21 loses the limit of the left baffle 32.

[0044] Also refer to Figures 10-16 The feeding mechanism includes a bottom ring 41, a resistance plate 42, a power plate 40, a rotating shaft 2 43, a discharge pipe 44, a bracket 45, a transmission shaft 46, a turntable 47, a power plate 2 48 and a torsion spring 49.

The discharge pipe 44 on the same side and the loading box 8 are grouped together, and the discharge pipes 44 in the same group are connected to the loading box 8. When material is added to the upper loading box 8, the material enters the corresponding discharge pipe 44.

The top end of the transmission shaft 46 is connected to the bottom end of the motor transmission device 5 through a bearing, and a turntable 47 is provided at the bottom end of the transmission shaft 46.

The bottom end of the motor transmission device 5 is provided with a plurality of inner steering shafts 1 54, outer steering shaft 1 55, inner steering shaft 2 56 and outer steering shaft 2 57. The inner steering shaft 1 54 and the outer steering shaft 1 55 are located on one side of the eccentric seat 4 to change the transmission direction of the belt 1 52. The inner steering shaft 2 56 and the outer steering shaft 2 57 are located on the other side of the eccentric seat 4 to change the transmission direction of the belt 2 53. Figure 14 、 Figure 15 and Figure 10 In the process of the revolution of the upper stirring shaft 2: 1. When the stirring part 3 rotates to the bottom of the left discharge pipe 44, the upper stirring shaft 2 rotates to drive the transmission shaft 46 on the left to rotate, and the transmission shaft 46 on the left drives the rotating shaft 50 on the right to rotate through the belt 2 53, and the rotating shaft 50 on the right drives the discharge port of the right discharge pipe 44 to be opened, and the material is discharged downward from the side without the stirring part 3, that is, the stirring part 3 is on the left and the material falls from the right; 2. When the stirring part 3 is located directly below the right discharge pipe 44, the upper stirring shaft 2 rotates to drive the transmission shaft on the right 46 rotates, the transmission shaft 46 on the right drives the rotating shaft 50 on the left to rotate through the belt 1 52, and the rotating shaft 50 on the left drives the unloading plate 51 on the left to rotate, and the unloading port of the unloading pipe 44 on the left is opened, and the material is discharged downward from the side without the stirring part 3, that is, the stirring part 3 is on the right, and the material falls from the left. The stirring part 3 and the unloading pipe 44 that is unloading the material are respectively arranged on both sides of the stirring pot 7 to prevent the material from falling from directly above the stirring part 3 and to prevent the material from splashing out of the pot when adding the material, thereby ensuring the accuracy of the proportion of the material in the stirring pot 7.

[0050] The specific implementation method is as follows: when using, first, the height of the mixer can be shortened and the mixing pot 7 can be taken and placed flatly. The specific process is as follows:

[0051] The stirring blade 1 23 and the stirring blade 2 24 have two states: a working state and a folded state. In both states, the stirring blade 24 is fixedly connected to the lower stirring shaft 21. The difference is that: ① in the working state: the angle between the plane 1 201 and the plane 2 202 is reduced from ninety degrees to zero degrees, the plane 1 201 and the plane 2 202 are in contact with each other, the stirring blade 1 23 and the stirring blade 2 24 are parallel, and the angle between the inclined plane 1 203 and the inclined plane 2 204 is greater than ninety degrees; ② in the folded state: the angle between the plane 1 201 and the plane 2 202 is expanded from zero degrees to ninety degrees, and the stirring blade 1 23 and the stirring blade 2 24 are perpendicular.

[0052] The mixer runs according to the working program of the external controller. After the mixing is completed, the motor transmission device 5 stops rotating and the mixer stays at Figure 2In the position shown, the electric push rod 30 extends, driving the positioning block 31, the left baffle 32 and the right baffle 33 away from the second stirring blade 24, so that the left baffle 32 is separated from the lower stirring shaft 21, and the positioning block 31 is separated from the positioning groove 26. The connection between the second stirring blade 24 and the first stirring blade 23 loses the support of the positioning block 31. At this time, the end of the left baffle 32 away from the positioning block 31 is called the end surface 1. A gap is generated between the end surface 1 and the second stirring blade 24, leaving space for the stirring part 3 to rotate. The side opening 27 on the left side of the lower stirring shaft 21 loses the limit of the left baffle 32;

[0053] The process of taking out the stirring pot 7 after stirring is completed is as follows: take out the stirring pot 7, after the stirring pot 7 is separated from the supporting plate 6, move the stirring pot 7 straight to the left, after the right wall of the stirring pot 7 contacts the stirring blade 2 24, push the stirring blade 2 24 to the left, the stirring blade 2 24 rotates upward ninety degrees, and the top of the stirring pot 7 is in contact with the edge of the stirring blade 2 24, and the stirring pot 7 is taken out, shortening the distance between the stirring pot 7 and the stirring part 3 when taking the material, and there is no need to tilt the stirring pot 7 when taking it. When the stirring blade 2 is rotated 90 degrees, the stirring blade 2 is driven by the stirring blade 1 23 to rotate upward synchronously. After the stirring blade 1 23 contacts the motor transmission device 5, the stirring blade 1 23 has lost the support of the positioning block 31, and the stirring blade 2 is driven by its own power to droop downward. The stirring blade 1 23 drives the sleeve 25 to rotate around the central axis 22, that is, the stirring blade 1 23 and the sleeve 25 rotate at the same time, and the outer edge of the stirring blade 1 23 approaches the stirring blade 2 24. The width of the positioning groove 26 gradually decreases, and the angle between the plane 1 201 and the plane 2 202 is expanded from zero to 90 degrees. The stirring blade 1 23 and the stirring blade 2 24 are perpendicular, and the stirring blade 1 23 and the stirring blade 2 24 are folded together. At this time, the stirring blade 1 23 and the stirring blade 2 24 are in a folded state, shortening the distance between the stirring part 3 and the motor transmission device 5. After the stirring pot 7 is separated from the stirring part 3, the stirring part 3 is in its own When the stirring pot 7 needs to be placed, the stirring blade 2 is pushed to the left by a tool, so that the stirring blade 2 is rotated upward by ninety degrees again, and then the stirring pot 7 is placed on the supporting plate 6, and the stirring blade 1 is rotated by a tool so that the angle between the plane 1 201 and the plane 2 202 is reduced from ninety degrees to zero, and the plane 1 201 is aligned with the plane 2 202, and the stirring blade 1 23 and the stirring blade 2 24 are parallel. Press the control button, the electric push rod 30 contracts and drives the positioning block 31, the left baffle 32 and the right baffle 33 to move closer to the stirring blade 2 24, completing the reset, and the positioning block 31 enters the positioning groove 26, and supports the connection between the stirring blade 2 24 and the stirring blade 1 23. The left baffle 32 is blocked at the side opening 27, and the lower stirring shaft 21 cannot rotate to the left around the rotating shaft 1. At this time, the stirring blade 1 23 and the stirring blade 2 24 are in working state.

[0054] Second: quantitative feeding while preventing material splashing;

[0055] refer to Figure 14 、 Figure 15 and Figure 10 In the process of the revolution of the upper stirring shaft 2: 1. When the stirring part 3 rotates to the bottom of the left discharge pipe 44, the left transmission shaft 46 is driven to rotate by the rotation of the upper stirring shaft 2, and the left transmission shaft 46 drives the right rotating shaft 50 to rotate through the belt 2 53, and the right rotating shaft 50 drives the discharge port of the right discharge pipe 44 to be opened, and the material is discharged downward from the side without the stirring part 3, that is, the stirring part 3 is on the left and the material falls from the right; 2. When the stirring part 3 is located directly below the right discharge pipe 44, the upper stirring shaft 2 rotates to drive the right transmission shaft 46 to rotate, and the right transmission shaft 46 drives the left rotating shaft 50 to rotate through the belt 1 52, and the left rotating shaft 50 drives the left discharge plate 51 to rotate, and the discharge port of the left discharge pipe 44 is opened, and the material is discharged downward from the side without the stirring part 3, that is, the stirring part 3 is on the right and the material falls from the left. The stirring part 3 and the discharge pipe 44 that is discharging the material are respectively arranged on both sides of the stirring pot 7.

[0056] The specific process is as follows: the rotation direction of the upper stirring shaft 2 is controlled by the motor transmission device 5, and the upper stirring shaft 2 drives the bottom ring 41 to rotate synchronously;

[0057] refer to Figure 10-12 In the loading state, the bottom ring 41 rotates counterclockwise, and the bottom ring 41 drives the power plate 1 40 to rotate counterclockwise around the upper stirring shaft 2. First, when the power plate 1 40 contacts the power plate 2 48 on the right, the resistance plate 42 supports the power plate 1 40, and the power plate 1 40 shifts the power plate 2 48 on the right, and the power plate 2 48 on the right rotates clockwise around the right turntable 47, thereby driving the right transmission shaft 46 to rotate clockwise; Second, similarly, refer to Figure 13 In the figure, when the power plate 1 40 contacts the power plate 2 48 on the left, the power plate 1 40 pushes the power plate 2 48 on the left, and the power plate 2 48 on the left rotates clockwise around the turntable 47 on the left, thereby driving the transmission shaft 46 on the left to rotate clockwise; through the coordination of the rotation and revolution of the upper stirring shaft 2, the power plates 2 48 on both sides are driven to contact the power plate 1 40 alternately, thereby driving the transmission shafts 46 on both sides to rotate alternately. When the upper stirring shaft 2 rotates and drives the transmission shaft 46 to rotate, it drives the torsion spring 49 to rotate. When the upper stirring shaft 2 rotates and drives the power plate 2 48 to separate from the power plate 1 40, the elastic force of the torsion spring 49 itself drives the transmission shaft 46 to rotate in the opposite direction and reset.

[0058] In the non-loading state: the bottom ring 41 rotates clockwise. First, when the power plate 1 40 contacts the power plate 2 48 on the right, within the same group, the power plate 1 40 rotates to the side away from the resistance plate 42, and the power plate 1 40 cannot drive the power plate 2 48 on the right to rotate, so that the transmission shaft 46 on the right does not rotate; second, similarly, when the power plate 1 40 contacts the power plate 2 48 on the left, within the same group, the power plate 1 40 rotates to the side away from the resistance plate 42, and the power plate 1 40 cannot drive the power plate 2 48 on the left to rotate, so that the transmission shaft 46 on the left does not rotate.
