Description

Technical Field

[0001] The present invention relates to the technical field of material stirring and mixing equipment, in particular to a stirrer with a vibration feedback function. Background Art

[0002] The stirring device of a mixer is used to mix materials and is widely used in new energy, chemical, pharmaceutical, metallurgical and food industries. In the prior art, the stirring group of a mixer has a variety of structural forms, and the stirring group with a stirring paddle structure is widely used for its uniform stirring effect. During the working process of the stirring group with a stirring paddle structure, its stirring trajectory is a spiral shear type, which can make the material change its position in the axial direction so as to be fully mixed, and the stirring is uniform and without dead angles.

[0003] At present, in order to improve the uniformity of material mixing, the stirring group of the stirring paddle mechanism is usually set no more than 10 mm away from the wall and bottom of the mixing tank. However, when stirring materials with high viscosity, the reaction force of the material on the stirring group is relatively large. In addition, the internal space of the stirring group is in a vacuum state, resulting in the stirring position offset of the stirring group or deformation of the stirring group during operation after long-term operation, which then hits the wall and bottom of the mixing tank, causing stirring failure.

[0004] Therefore, how to ensure that the mixing group can mix the materials smoothly and effectively is a technical problem that those skilled in the art need to solve urgently. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide a mixer with a vibration feedback function to ensure that the mixing group can mix the materials smoothly and effectively.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A mixer with a vibration feedback function, comprising a mixing tank and a mixing group, and further comprising:

[0008] a vibration detection module, fixedly disposed on the side wall of the stirring tank, for detecting a vibration signal of the side wall of the stirring tank during the stirring process of the stirring group;

[0009] The control module is electrically connected to the vibration detection module to receive the vibration signal detected by the vibration detection module and to send out an alarm signal when the vibration signal suddenly changes.

[0010] Preferably, in the above-mentioned mixer with vibration feedback function, the vibration detection module is evenly arranged with four detection points on the circumference of the side wall of the mixing tank, and the control module is electrically connected to the first driving device, and the first driving device is used to drive the mixing group to move;

[0011] When the control module detects a sudden change in the vibration signal at any of the detection points, the control module controls the first driving device to drive the stirring group away from the corresponding detection point.

[0012] Preferably, in the above-mentioned mixer with vibration feedback function, an independent vibration sensor is provided at each detection point, and detection ranges of adjacent vibration sensors are spaced apart by a first preset distance.

[0013] Preferably, in the above-mentioned mixer with vibration feedback function, the height position of the vibration detection module on the side wall of the mixing tank is the same as the height position of the maximum mixing diameter of the mixing group.

[0014] Preferably, in the above-mentioned blender with vibration feedback function, a mounting seat is provided on the blending tank, the vibration detection module is threadedly connected to the mounting seat, and one end of the vibration detection module abuts against the outer wall of the inner cylinder of the blending tank.

[0015] Preferably, in the above-mentioned blender with vibration feedback function, the control module includes a PLC (programmable logic controller) and a touch screen, and the touch screen is used to display the real-time vibration value of the mixing tank at the setting position of the vibration detection module.

[0016] Preferably, in the above-mentioned mixer with vibration feedback function, the alarm signal is an easily detectable sound, light or electrical signal.

[0017] Preferably, in the above-mentioned mixer with vibration feedback function, the first driving device is a motor.

[0018] It can be seen from the above technical solution that the mixer with vibration feedback function provided by the present invention includes a mixing tank, a mixing group, a vibration detection module and a control module, wherein the mixing tank is used to hold the material to be mixed, and is preferably a jacketed structure commonly used in the prior art, and the mixing group is preferably a paddle-type mixing group to ensure uniform mixing process. In particular, the mixer with vibration feedback function provided by the present invention is provided with a vibration detection module on the side wall of the mixing tank, which is used to detect the vibration signal of the side wall of the mixing tank during the mixing process of the material. It is also to detect in time when the mixing group collides with the side wall of the mixing tank. Specifically, when the mixing group runs at high speed and deviates and collides with the side wall of the mixing tank, the vibration detection module will detect a sudden change in the vibration signal. Therefore, the vibration signal mutation signal is used as a sign that the mixing tank is hit, and the operator uses it as a standard for stopping the mixer for inspection and maintenance. Correspondingly, the sudden change information of the vibration signal needs to be communicated to the outside world through the control module. The control module is electrically connected to the vibration detection module, which is used to receive the vibration signal detected by the vibration detection module and send an alarm signal for reference by the operator when the vibration signal suddenly changes. The mixer provided by the present invention is provided with a vibration detection module on the side wall of the mixing tank to detect the vibration state of the side wall of the mixing tank. At the same time, a control module is provided to receive the vibration signal detected by the vibration detection module, so as to timely alarm when the mixing group collides with the mixing tank, prompting the operator to shut down the mixer for maintenance, thereby avoiding damage to the mixing group and the mixing tank, and also avoiding affecting the mixing effect of the material due to the displacement of the mixing group shape.

[0022] The core of the present invention is to disclose a mixer with a vibration feedback function to ensure that the mixing group can mix materials smoothly and effectively.

[0023] To help those skilled in the art better understand the present invention, embodiments of the present invention are described below with reference to the accompanying drawings. The embodiments described below do not limit the invention as set forth in the claims. Furthermore, the entire contents of the embodiments described below are not necessarily required to provide the solution to the invention as set forth in the claims.

[0024] like Figure 1 As shown, the mixer with vibration feedback function provided by the embodiment of the present invention includes a mixing tank 10, a mixing group 20, a vibration detection module 30 and a control module, wherein the mixing tank 10 is used to hold the material to be mixed, and its structural form is preferably a jacketed structure commonly used in the prior art, and the mixing group 20 is preferably a mixing paddle-type mixing group 20 to ensure uniformity of the mixing process. In particular, the mixer with vibration feedback function provided by the embodiment of the present invention is provided with a vibration detection module 30 on the side wall of the mixing tank 10 for detecting the vibration signal of the side wall of the mixing tank 10 during the material mixing process, which is also for detecting the vibration signal of the side wall of the mixing tank 10 when the mixing group 20 collides with the side wall of the mixing tank 10 It can be discovered in time to avoid accidents caused by the deviation of the mixing group 20; specifically, when the mixing group 20 runs at high speed and deviates and collides with the side wall of the mixing tank 10, the vibration detection module 30 will detect a sudden change in the vibration signal. Therefore, the embodiment of the present invention uses the signal of the sudden change in the vibration signal as a sign that the mixing tank 10 has been hit, and the operator uses this as a standard for shutting down the mixer for inspection and maintenance; correspondingly, the sudden change information of the vibration signal needs to be conveyed to the outside world through the control module. The control module is electrically connected to the vibration detection module 30, which is used to receive the vibration signal detected by the vibration detection module 30 and send an alarm signal for the operator's reference when the vibration signal suddenly changes.

[0025] The mixer provided by an embodiment of the present invention is provided with a vibration detection module 30 on the side wall of the mixing tank 10 to detect the vibration state of the side wall of the mixing tank 10. At the same time, a control module is provided to receive the vibration signal detected by the vibration detection module 30, so as to timely alarm when the mixing group 20 collides with the mixing tank 10, prompting the operator to shut down the mixer for maintenance, thereby avoiding damage to the mixing group 20 and the mixing tank 10, and also avoiding affecting the mixing effect of the material due to the displacement of the shape of the mixing group 20.

[0026] It should be noted that when the control module does not alarm, the above structure considers that the mixing group 20 is working in a standard posture, and since a collision detection structure is set, the mixing group 20 can be set as close to the side wall of the mixing tank 10 as possible during the setting process, and the vibration signal of the side wall of the mixing tank 10 is used as a shutdown indication, thereby reducing the generation of dead corners in the mixing process and making the mixing process of the material more uniform.

[0027] Taking into account that no serious accident will occur when the stirring group 20 slightly collides with the stirring tank 10, but arbitrary shutdown will cause waste of materials, in order to timely correct the stirring group 20 during its operation, in a specific embodiment of the present invention, the vibration detection module 30 is evenly arranged with several detection points on the circumference of the side wall of the stirring tank 10. In a preferred embodiment of the present invention, four detection points are evenly arranged on the circumference of the side wall of the stirring tank 10, and the control module is electrically connected to the first drive device to adjust the first drive device. The first drive device is transmission-connected to the stirring group 20 for driving the stirring group 20 to move its position in the stirring tank 10. In the above embodiment, the control module is connected to the vibration The dynamic detection module 30 is electrically connected, and when the vibration signal at any detection point among the four detection points suddenly changes, the first drive device is controlled to drive the stirring group 20 away from the corresponding detection point. The advantage of the above-mentioned feedback system is that the position of the stirring group 20 is fed back in real time through the four detection points during the working process of the stirring group 20. When the stirring group 20 is close to the side wall of the stirring tank 10 at any detection point, it will cause the vibration signal of the side wall of the stirring tank 10 to suddenly change, so that the control system adjusts the position of the stirring group 20 to keep it away from the corresponding detection point, avoiding the stirring group 20 from further colliding with the stirring tank 10, realizing dynamic adjustment of the stirring group 20, and saving production resources such as materials and electricity.

[0028] In order to further optimize the above technical solution, in the above embodiment, an independent vibration sensor is provided at the position of each single detection point to detect the vibration signal of the side wall of the stirring tank 10, and the detection ranges of adjacent vibration sensors are set at a first preset distance. The first preset distance is determined by the designer according to needs, and its value is not less than 0 to ensure that adjacent vibration sensors will not have a detection impact, that is, when the stirring group 20 collides with the side wall of the stirring tank 10 within the detection range of a single vibration sensor, the vibration signal of the side wall of the stirring tank 10 is only detected by a single vibration sensor, and at the same time, the control module adjusts the position of the stirring group 20 according to the vibration signal information detected by the corresponding vibration sensor. The vibration signal of the side wall of the stirring tank 10 will not be detected by the two vibration sensors, so as to mislead the adjustment of the control module.

[0029] It should be noted that, in a preferred embodiment of the present invention, the first preset distance is 0, that is, the detection range of the multiple vibration sensors covers the entire area within the stirring tank 10 to ensure the accuracy of the control module in adjusting the position of the stirring group 20.

[0030] Furthermore, in a specific embodiment of the present invention, in order to improve the accuracy of the vibration detection module 30 in detecting the vibration signal of the side wall of the stirring tank 10, in the height direction of the side wall of the stirring tank 10, the setting height position of the vibration detection module 30 is the same as the height position of the maximum stirring diameter of the stirring group 20, that is, the vibration detection module 30 is set at the position where the stirring group 20 is most likely to collide with the stirring tank 10, so as to detect the collision information between the stirring group 20 and the stirring tank 10 at the first time.

[0031] Furthermore, the mixer with vibration feedback function provided by the embodiment of the present invention is provided with a mounting base 40 on the mixing tank 10, and the mounting base 40 is preferably welded and fixed to the mixing tank 10, and the mounting base 40 is used to fix the vibration detection module 30, and the vibration detection module 30 is preferably threadedly connected to the mounting base 40 to facilitate the disassembly and assembly of the vibration detection module 30. It should be noted that the mixing tank 10 with a jacket structure has an inner cylinder and an outer cylinder, and one end of the vibration detection module 30 abuts the outer wall of the inner cylinder of the mixing tank 10, so that the vibration detection module 30 can sensitively and accurately detect the vibration signal of the side wall of the mixing tank 10, and at the same time, the vibration detection module 30 does not extend into the interior of the cylinder, which can prevent the material in the mixing tank 10 from leaking, thereby improving safety.

[0032] Furthermore, in a specific embodiment of the present invention, the control module includes a PLC (programmable logic controller) for signal reception and calculation processing, and a touch screen for displaying signals, wherein the touch screen is used to display the real-time vibration value of the mixing tank 10 at the setting position of the vibration detection module 30 for reference by the operator.

[0033] It should be noted that a single chip microcomputer can also be used for signal reception and calculation processing.

[0034] It should be further explained that the touch screen can be provided with a switch button to select whether the vibration value is displayed in a numerical value, a bar graph, or the like.

[0035] Furthermore, in order to issue an alarm signal that is easily perceived by the operator when a sudden change occurs in the vibration signal, the control module controls the issuance of an easily detectable sound, light or electrical signal, including but not limited to one or more of a buzzer, a color indicator light and a signal indication.

[0036] Furthermore, in the mixer with vibration feedback function provided in an embodiment of the present invention, the first driving device is a motor, and the driving motor is sensitively responsive to the adjustment of the control module to ensure timely adjustment of the position of the mixing group 20 and smooth progress of the mixing process.
