Description

Technical Field

[0001] The present application relates to the technical field of stirring equipment, and in particular to a stirrer with an intelligent monitoring function. Background Art

[0002] Traditional concrete mixers pour sand, lime, gravel and water into the mixing tank in sequence through a bucket. Therefore, the materials in the mixing tank are layered at first. During continuous mixing, the materials move relative to each other to be mixed evenly. However, whether the mixing degree of the materials meets the requirements can mostly only be judged visually. Of course, it can also be tested by sampling. The first method has low judgment accuracy, while the second method is more troublesome and costly. Utility Model Content

[0003] The purpose of the present application is to provide a stirrer that can quickly and accurately judge the degree of material mixing.

[0004] To achieve the above objectives, the present application provides a stirrer with an intelligent monitoring function: comprising a tank body, a stirring mechanism being arranged inside the tank body, a configuration plate being fixedly connected to the side wall of the tank body, a plurality of impact detectors being arranged on the configuration plate, the impact detectors being arranged equidistantly in the vertical direction, each of the impact detectors being suitable for detecting the impact frequency of the solid material in the tank body at a corresponding height, a control panel being arranged outside the tank body, and all of the impact detectors being electrically connected to the control panel to transmit detection information to a computer.

[0005] Preferably, the impact detector includes a sealing member, wherein the sealing member has a mounting seat fixedly connected to the side of the configuration plate, the mounting seat is located in the tank body, and an active cavity is defined on the side of the mounting seat facing away from the configuration plate, the mounting seat is fixedly connected to an inner wall of the active cavity with a pair of pressure sensors, and a detection head located between the two pressure sensors is also rotatably connected in the active cavity, and provides an impact signal to the pressure sensor through its own swing.

[0006] As a preferred embodiment, the mounting seat is provided with a fixed shaft with a vertical axis in the active cavity, and the detection head includes a sleeve, which is sleeved outside the fixed shaft to form a rotating pair. The sleeve is located on the side of the active cavity and has a paddle for absorbing obvious stone impacts. The impact force of the liquid flow can also cause the paddle to deviate and apply force to the pressure sensor, but compared with the impact of the stone, the force generated by the liquid flow is obviously very soft, so although the pressure sensor receives the signal of the liquid flow impact, it does not output a signal to the control panel, that is to say, the pressure sensor only records the stone impact event.

[0007] Preferably, the configuration plate is provided with through holes, the number of which corresponds to the number of the impact detectors and is also equidistantly arranged from bottom to top, the mounting seat has a blocking column on the side facing the configuration plate, the end of the blocking column passes through the through hole and is fixedly connected with a wiring terminal, all of the wiring terminals are communicatively connected to the processor in the control panel through signal lines, thereby achieving stable power supply and signal transmission.

[0008] Preferably, the side wall of the tank body is provided with a through groove penetrating the inner and outer walls, the configuration plate is fixedly connected in the through groove, one side of the configuration plate is flush with the inner wall of the tank body, and the other side is flush with the outer side surface of the tank body, so that the inner and outer walls of the tank body remain flat.

[0009] Preferably, the stirring mechanism includes a motor and a reducer fixedly connected to the top surface of the tank body, the output end of the reducer is fixedly connected to a stirring shaft, and the part of the stirring shaft located inside the tank body is fixedly connected to a stirring rod, which directly pushes the material in the tank body when rotating.

[0010] Preferably, the top of the tank body is provided with an axial hole for the stirring shaft to pass through to form a rotating pair. The top of the tank body is also provided with an injection end, and the bottom of the tank body is provided with a discharge end, from which the mixed material is discharged.

[0011] As a preferred embodiment, a bracket is fixedly connected to the bottom of the tank body, and the bottom surface of the bracket is lower than the discharge end, so as to reserve sufficient installation space for the pipeline structure below the tank body.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] (1) By setting up impact detectors arranged vertically and calculating the impact frequency of stones detected by each detector, the uniformity of stones in the mixing system can be judged. When the stones are distributed in a relatively uniform state in the vertical direction, it means that other substances in the mixing system must also be fully mixed. Therefore, the agitator can judge the mixing degree of the materials by itself, and the monitoring accuracy is high and the monitoring cost is low;

[0014] (2) Monitoring the mixing degree of materials in the tank does not require manual operation, which is convenient and quick, with lower time cost and higher monitoring efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1-8 The stirrer with intelligent monitoring function shown in the figure comprises a cylindrical tank body 2, in which a stirring mechanism 1 is arranged, and the specific structure of the stirring mechanism 1 comprises a motor 101 and a reducer 102 fixedly connected to the top surface of the tank body 2. In fact, only the shells of the motor 101 and the reducer 102 are fixedly connected to the top surface of the tank body 2, and the output end of the motor 101 is electrically connected to the input end of the reducer 102. The output end of the reducer 102 is fixedly connected to a stirring shaft 103, and the axis of the stirring shaft 103 is colinear with the axis of the tank body 2. The part of the stirring shaft 103 located in the tank body 2 is fixedly connected to a stirring rod 104, which is a component that directly applies thrust to the material in the tank body 2. An axial hole 201 is opened on the top of the tank body 2, just A bearing structure is usually provided in the shaft hole 201 for the stirring shaft 103 to pass through and form a rotating pair, and the bearing structure is sleeved on the outside of the stirring shaft 103 to convert the sliding friction between the stirring shaft 103 and the shaft hole 201 into rolling friction, thereby effectively reducing the friction resistance and improving the rotation stability of the stirring shaft 103. A filling end 203 is also provided on the top of the tank body 2, through which solid and liquid materials are added to the tank body 2, and a discharge end 204 is provided at the bottom of the tank body 2, through which the mixed materials are discharged. A bracket 6 is also fixedly connected to the bottom of the tank body 2 for maintaining the stability of the entire agitator. The bottom surface of the bracket 6 is lower than the discharge end 204. The bracket 6 allows the tank body 2 to be suspended at a certain height from the ground, leaving sufficient pipeline installation space below the discharge end 204.

[0029] The side wall of the tank body 2 is fixedly connected with a configuration plate 3, and the configuration plate 3 is in the shape of a vertical strip. The side wall of the tank body 2 is provided with a through groove 202 that penetrates the inner and outer walls. The configuration plate 3 is fixedly connected in the through groove 202, and usually, one side of the configuration plate 3 is flush with the inner wall of the tank body 2, and the other side is flush with the outer side surface of the tank body 2. In this way, even if the tank body 2 is provided with a through groove 202, its inner and outer walls are relatively flush. A number of impact detectors 4 are arranged on the configuration plate 3, and each impact detector 4 can detect the impact frequency of the solid material in the tank body 2 at its height. By judging whether the impact frequencies at different heights are close, the mixing degree of the upper and lower materials can be judged. The impact detectors 4 are arranged equidistantly in the vertical direction, which is conducive to uniform detection.

[0030] The specific structure of the impact detector 4 includes a sealing member 410, the sealing member 410 has a mounting seat 413 fixedly connected to the side of the configuration plate 3, the mounting seat 413 is completely located in the tank body 2, and a fan-shaped active cavity 414 is opened on the side of the mounting seat 413 facing away from the configuration plate 3. The mounting seat 413 is fixedly connected to a pair of pressure sensors 403 on the inner wall of the active cavity 414. The two pressure sensors 403 are respectively located on the left and right inner walls of the active cavity 414. A detection head 420 located between the two pressure sensors 403 is also rotatably connected in the active cavity 414. The detection head 420 is the only one in the impact detector 4 that can be moved. The movable part, the mounting seat 413 is provided with a fixed shaft 415 with a vertical axis in the active cavity 414, the axis of the fixed shaft 415 is parallel to the axis of the stirring shaft 103, the detection head 420 includes a sleeve 421 with a center hole, the sleeve 421 is sleeved outside the fixed shaft 415 and cooperates to form a rotating pair, the sleeve 421 is located on the side of the active cavity 414 and has a paddle 422, the paddle 422 is located between the sensing surfaces of the two pressure sensors 403, and the paddle 422 will transfer the instantaneous impact force to the biased pressure sensor 403 when impacted, thereby recording the number of impacts per unit time and calculating the impact frequency.

[0031] A control panel 5 is provided outside the tank body 2 for controlling the operation of the equipment and processing data, which is equivalent to a computer. All impact detectors 4 are electrically connected to the control panel 5. In order to ensure that the signal of the pressure sensor 403 can be output to the outside, a through hole 301 is opened on the configuration plate 3. The number of the through holes 301 corresponds to the number of the impact detectors 4, and they are also arranged equidistantly from bottom to top to ensure that each impact detector 4 has a position for installation. The side of the mounting seat 413 facing the configuration plate 3 is provided with a blocking column 411, which is just inserted into the through hole 301 to completely block the through hole 301. The blocking column 411 has a hollow structure for the signal line to pass through. The end of the blocking column 411 passes through the through hole 301 and is fixedly connected with a terminal 412. All the terminals 412 can be communicated with the processor in the control panel 5 through a longer signal line to realize real-time monitoring of the detection signal of the pressure sensor 403.

[0032] Working principle: sand, lime, water and gravel are put into the tank 2 through the injection end 203, and start to rotate and mix under the drive of the stirring mechanism 1. During the rotation, the gravel in the mixing system will hit the paddle 422 to make the pressure sensor 403 generate an obvious signal, which is transmitted to the control panel 5. The number of collisions of each collision detector 4 per unit time is calculated, and the collision frequency of the corresponding height is reached. The collision frequency of the gravel is the same as the density of the gravel at the height of the mixing system. When the collision frequency fed back by each collision detector 4 is similar, it means that the gravel has been fully diffused in the flow system and the distribution density in the vertical direction is also very uniform. At this time, other substances in the concrete system that are more easily exchanged must have been fully mixed. Therefore, the agitator can automatically detect whether the internal materials are mixed to an appropriate degree, so as to automatically determine when to stop stirring and discharge the mixed materials.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application.
