Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses a stirring and mixing device for improving material weighing precision, which comprises a rack 1 and a stirring kettle 2, wherein the rack 1 is used for supporting the stirring kettle 2; a feeding pipe 11 is fixed on the stirring kettle 2 and communicated with the stirring kettle 2, and the feeding pipe 11 is used for adding ground powder into the stirring kettle 2. Meanwhile, a feedback mechanism 3 is arranged on the frame 1, and the feedback mechanism 3 is used for controlling the addition amount of the powder.

As shown in fig. 1 and 2, a material conveying pump 12 is placed on the frame 1, and the material conveying pump 12 is communicated with a feeding pipe 11 and used for providing conveying power for materials.

The weighing sensors 31 are electrically connected with the material conveying pump 12, and can output starting or stopping electric signals to the material conveying pump 12, and the sum of the pressure increase amounts detected by the three weighing sensors 31 is the total weight of the materials entering the stirring kettle 2 in the feeding process.

As shown in fig. 2, one side of the sensing seat 23 facing the ground is provided with an abutting plate 33, and two opposite sides of the abutting plate 33 are abutted by the abutting plate 33 and the sensing end of the weighing sensor 31 respectively; because the whole weight of stirred tank 2 is great, when certain part on frame 1 takes place deformation error, stirred tank 2's axis will take place the deviation, and its axis will have the skew weighing sensor 31's of certain probability arrangement axis, and the material distribution in the stirred tank also demonstrates the state of not centering this moment, is unfavorable for the quick, evenly stirring of material to mix. Therefore, the feedback mechanism 3 further comprises a leveling assembly 32, and the leveling assembly 32 is used for adjusting the relative distance between the abutting plate 33 and the induction seat 23 so as to realize the axial angle adjustment of the stirring tank 2.

As shown in fig. 2, the leveling assembly 32 includes an adjusting bolt 321 and an adjusting guide post 322, the adjusting bolt 321 is located on one side of the abutting plate 33 departing from the load cell 31, the adjusting bolt 321 is in threaded connection with the induction seat 23, and an end of the adjusting bolt 321 abuts against one side of the abutting plate 33 departing from the load cell 31. The adjusting guide post 322 is welded and fixed on one side of the induction seat 23 facing the weighing sensor 31, the length direction of the adjusting guide post 322, the axis of the adjusting bolt 321 and the axis of the stirring kettle 2 are all parallel to each other, and the adjusting guide post 322 penetrates through the abutting plate 33 to provide stable movement guide for the abutting plate. According to the law of mechanics, when the overall mass distribution of the empty stirred tank 2 is uniform, if the pressures detected by the three weighing sensors 31 are the same, it indicates that the gravity center of the stirred tank 2 is located on the array axis of the three weighing sensors 31.

As shown in fig. 1, the apparatus further includes a service assembly 4, and the service assembly 4 is used to temporarily support the stirred tank 2 when the load cell 31 malfunctions, so as to provide a space for an operator to remove or replace the load cell 31. Overhaul subassembly 4 and include base 41, supporting seat 42 and supporting screw 43, base 41 and frame 1 fixed connection, supporting seat 42 and stirred tank 2's lateral wall fixed connection, supporting seat 42 is located base 41 directly over, and supporting seat 42 is three with base 41 equally, and its mode of arranging is the same with response seat 23, and this is no longer repeated here. Leave the clearance between supporting seat 42 and the base 41, supporting screw 43 and supporting seat 42 threaded connection, the axis of supporting screw 43 is parallel with stirred tank 2's axis, in the in-process of weighing sensor 31 normal use, the tip of supporting screw 43 does not touch with base 41, and if need take off weighing sensor 31, rotate supporting screw 43, make its tip butt base 41, continue to rotate, can make the bracing piece pass through supporting seat 42 with stirred tank 2 lifting, so that make induction seat 23 leave weighing sensor 31, the operator alright take off weighing sensor 31 during this period. In order to reduce the mutual wear between the end of the supporting screw 43 and the base 41, a supporting plate 411 is rotatably connected to the side of the base 41 facing the supporting seat 42, the plate surface of the supporting plate 411 faces the supporting screw 43, and the supporting plate 411 is coaxial with the supporting screw 43, that is, when the supporting seat 42 is supported by the supporting screw 43, the plate surface of the supporting plate 411 directly abuts against the end of the supporting screw 43.

As shown in fig. 1, since there is still a certain distance from the material delivery pump 12 to the stirring kettle 2, there is a certain hysteresis in the feedback control of the material delivery pump 12 by the weighing sensor 31, in order to improve the accuracy of the amount of the material entering the stirring kettle 2, a spare feed opening 21 is provided on the stirring kettle 2, and a plugging cover 22 for plugging the spare feed opening 21 is hinged at the spare feed opening 21 of the stirring kettle 2; when final actual feeding volume is great with the default deviation, the manual increase and decrease regulation is carried out to the material in stirred tank 2 to operator's accessible reserve charge door 21.

The implementation principle of the stirring and mixing device for improving the material weighing precision is as follows:

before feeding, the posture of the stirring kettle 2 is calibrated and adjusted according to the sensing result of the retransmission sensor 31 in the no-load state of the stirring kettle 2, and the material conveying pump 12 is started under the stable condition of the state of the stirring kettle 2 to perform feeding operation. When the weight sensor 31 detects that the weight change is about to reach the preset value, a signal is sent to the material conveying pump 12 to stop the operation of the material conveying pump, and then the material in the stirring kettle 2 is manually increased or decreased according to the final data displayed by the weight sensor 31, so that the material in the stirring kettle 2 finally reaches the preset value.
