Description

Technical Field

[0001] The present application relates to the field of aluminum alloy equivalent detection, and in particular to a multifunctional automatic aluminum liquid hydrogen measurement device and a control system thereof. Background Art

[0002] The aluminum liquid hydrogen meter is an advanced industrial testing equipment, which is used to measure the hydrogen content and density equivalent in aluminum liquid. It plays a vital role in the field of aluminum alloy production and the monitoring of the quality and performance of aluminum alloy castings.

[0003] After the aluminum liquid has gone through the degassing and refining process, the test personnel use the aluminum liquid hydrogen meter to solidify the aluminum liquid sample in a vacuum or low-pressure environment and measure its density to determine whether the same batch of aluminum liquid meets the use standards; in addition, during the solidification of the aluminum liquid, excessive hydrogen content in the aluminum liquid can produce pores on the surface or inside the aluminum liquid casting, which will greatly affect the structural strength and aesthetics of the aluminum liquid casting; therefore, creating a vacuum environment to solidify the aluminum liquid and eliminating the interference of external environmental gases can more accurately measure the hydrogen content of the batch of aluminum liquid. The surface pore distribution of the aluminum liquid after solidification under a vacuum environment is compared with the visual observation in a normal environment to determine whether the batch of aluminum liquid is usable.

[0004] However, the function of the aluminum liquid hydrogen meter under the existing technology is too simple. It can only measure multiple aluminum liquids one by one, and the degree of automation is low. It cannot be automatically controlled and needs to be done manually by the test personnel. The measurement efficiency needs to be improved. Summary of the invention

[0005] In order to improve the degree of automation of the aluminum liquid hydrogen measuring device and increase the functions of the aluminum liquid hydrogen measuring device, the present application provides a multifunctional automated aluminum liquid hydrogen measuring device and a control system thereof.

[0006] On the one hand, the present application provides a multifunctional automated aluminum liquid hydrogen measurement device adopts the following technical solution:

[0007] A multifunctional automatic aluminum liquid hydrogen measuring device, comprising a main frame, a vacuum pump is arranged at the bottom of the main frame, and further comprising:

[0008] A placement plate is slidably arranged on the top of the main frame, and a plurality of the placement plates are distributed parallel to one side edge of the main frame. The sliding directions of the plurality of placement plates are the same, and a ring groove is provided on the top of the placement plate;

[0009] The vacuum cover corresponds to the placement plate one by one, and its bottom edge is adapted to the annular groove and buckled on the placement plate. The vacuum cover body has a hole, and the hole part is connected with a vacuum tube. The vacuum cover and the vacuum pump are connected through the vacuum tube; the top of the vacuum cover is formed with a buckle structure;

[0010] An arm rod is horizontally arranged, one end of which is vertically slidably connected to the main frame, and the other end of which is connected to a buckle structure on the vacuum cover to drive the vacuum cover to move vertically;

[0011] The measuring component is arranged on the main frame and is used for measuring the vacuum degree inside the vacuum cover and the weight of the aluminum part.

[0012] By adopting the above technical solution, the main frame is the main part of the aluminum liquid hydrogen measuring device, the main components used for aluminum liquid hydrogen measuring are arranged on the main frame, and the vacuum pump is installed at the bottom of the main frame to avoid occupying the external space of the main frame;

[0013] The top of the main frame is set in a tabletop, on which a plurality of placement plates are arranged. Each placement plate is the experimental occurrence part of the aluminum liquid hydrogen measurement device, which can support the simultaneous measurement of multiple aluminum liquids and provide the same solidification time. After the aluminum liquid solidifies, it is convenient for the test personnel to visually compare and compare the surface pore distribution of the aluminum parts after each portion of aluminum liquid is solidified and formed; the experimental process is as follows: first, the test personnel put each preset amount of aluminum liquid into a crucible of the same structure, and place the crucibles on the placement plates in turn. After the aluminum liquid in all crucibles is stable, the arm drives the vacuum cover to move down and buckle into the annular groove on the placement plate. The bottom edge of the vacuum cover is adapted to the annular groove. The sealing performance of the vacuum cover is improved by the uneven annular groove, and a rubber sealing ring and other structures can be arranged in the annular groove to further reduce the possibility of air squeezing into the vacuum cover;

[0014] After the vacuum cover is buckled into the ring groove, the vacuum pump operates to extract the air inside the vacuum cover. Different air pressures can be set inside multiple vacuum covers, and hydrogen can be measured using the controlled variable method. In practical applications, a vacuum valve should be set at the part of the vacuum tube close to the vacuum cover to control the gas extraction speed and the airtightness of the vacuum cover. Holes can also be opened in other parts of the vacuum cover and vacuum valves can be set to measure after the measurement is completed.

[0015] After the measurement is completed, open the vacuum valve to connect the inside and outside of the vacuum cover, then use the arm to lift the vacuum cover and take out the solidified aluminum liquid.

[0016] Optionally, a weighing groove is provided at the end of the main frame corresponding to the conveying direction of the multiple placement plates, and the length of the weighing groove is greater than the distribution length of the multiple placement plates. The measuring component for measuring the weight of the aluminum parts is arranged on the bottom wall of the weighing groove and corresponds one by one to the multiple placement plates.

[0017] By adopting the above technical solution, the weighing slot is opened at one end of the conveying direction of the placement plate, and a weight sensor or other weighing components with a small number level should be set on its bottom wall;

[0018] The above-mentioned placement plate is transported to the weighing tank after the solidification process of the aluminum liquid is completed, so that the solidified aluminum parts are placed in the weighing tank for weighing, and the total mass of the crucible and the aluminum parts is obtained. The mass of the aluminum parts is obtained by subtracting the mass of the crucible under this model; in the above scheme, the length of the weighing tank is greater than the distribution length of the placement plate, so that the aluminum parts on each placement plate can be transported to the weighing tank.

[0019] Optionally, also include:

[0020] A slider is arranged on the bottom wall of each placement plate and is slidably connected to the top wall of the main frame. The main frame is provided with a slide groove parallel to the sliding direction of the slider, and the slide groove is connected to the weighing groove;

[0021] One end of the lifting plate is rotatably connected to the end of the slider away from the weighing slot, and rotates around the rotating end to lift the placement plate, so that the placement plate is tilted toward the side close to the weighing slot.

[0022] By adopting the above technical scheme, the slider and the lifting plate are necessary components for transporting the above-mentioned aluminum parts and crucibles from the placement plate to the weighing tank; first, the lifting plate is in a horizontal state, and its free end does not play any supporting role on the placement plate. When the aluminum liquid solidifies, the slider drives the placement plate to slide toward the weighing tank and transports it to one side of the placement plate. After the edge extends to the top of the weighing tank, the lifting plate rotates around the connection point, driving the placement plate to tilt downward to the side close to the weighing tank, and the aluminum parts slide down to the bottom wall of the weighing tank under the action of gravity.

[0023] In the above solution, the sliding movement of the slider can be achieved through a traditional drive solution of a screw rod combined with a motor.

[0024] Optionally, the arm is composed of a sleeve rod, so that the arm is a telescopic structure, and a structure for fixing the length of the arm is provided at the telescopic portion of the arm;

[0025] The portion of the main frame corresponding to the connection of the arm is provided with an active member for driving the arm to slide vertically.

[0026] By adopting the above technical scheme, the degree of automation of the aluminum liquid hydrogen measuring device enables the various components to operate in coordination, but long-term operation may lead to reduced coordination and loose connections, resulting in displacement of the initial position of the placement plate. In order to ensure the close fit between the bottom end of the vacuum cover and the annular groove, when the placement plate is displaced, the length of the arm is fine-tuned accordingly so that the vacuum cover connected by the buckle structure at the end of the arm can adapt to the displaced annular groove, and when the arm moves downward, the bottom edge of the vacuum cover can be smoothly snapped into the annular groove.

[0027] Optionally, a conveyor belt may be included to replace the placement plate, the belt surface of the conveyor belt is driven in the same direction as the conveying direction of the placement plate, and one end of the conveyor belt extends to above the weighing trough.

[0028] By adopting the above technical solution, the setting of the conveyor belt can reduce the cost of structural design. Under the technical solution of realizing sliding by the placement plate, it is necessary to groove the main frame, set screws, motors, sliders and the hinge mechanism supporting the placement plate, etc. The principle is simple but the actual design is more complicated and has more connecting structures. Therefore, this solution replaces all the above components used to drive the placement plate to slide and rotate and the placement plate body with a conveyor belt. The conveyor belt corresponds to the placement plate one by one, and the annular groove is opened on the belt surface;

[0029] In addition, the conveyor belt surface is relatively soft, and fitting into the bottom edge of the vacuum hood itself has a certain sealing effect. The bottom edge of the vacuum hood adapts to the annular groove opened on the conveyor belt surface to further enhance the sealing effect of the vacuum hood.

[0030] On the other hand, the present application provides a control system for a multifunctional automated aluminum liquid hydrogen measuring device using the following technical solutions:

[0034] The central control module receives and retrieves the detection data of the detection module, calculates and analyzes the data to obtain the overall operating status of each component, generates corresponding instructions according to the calculation results of the data and sends the instructions to the control module;

[0035] The external module provides a data transmission channel with external devices and connects external devices to increase functions.

[0038] Optionally, a wireless module is also included;

[0039] The wireless module is connected to the display module, the control module, and the central control module, and is used to wirelessly transmit control instructions of the central control module and the display module to the control module.

[0040] By adopting the above technical solution, the control system consists of a main control module responsible for data processing, a detection module responsible for data collection, a control module responsible for controlling the operation of components in the aluminum liquid hydrogen measurement layer, an external module for connecting other driving devices to expand functions, a display module for displaying the operating status of the aluminum liquid hydrogen measurement device, and a wireless module responsible for wireless transmission of various collected data;

[0041] The detection module includes various sensors arranged inside the aluminum liquid hydrogen measuring device, wherein a pressure sensor is selected for measuring the absolute pressure value in the vacuum cover, and a weight sensor is arranged on the bottom wall of the weighing tank for measuring the mass of the aluminum part after the aluminum liquid solidifies, and the weight change value is measured. The central control module receives the detection data uploaded by the weight sensor and the pressure sensor in real time, makes calculations, and obtains the absolute pressure value in the vacuum cover during the aluminum liquid hydrogen measurement process and the mass of the aluminum liquid after solidification;

[0042] The central control module analyzes the absolute pressure value uploaded by the above pressure sensor in real time to obtain the pressure value in each vacuum cover. If there is a deviation in the pressure value of one or more vacuum covers, the valve at the vacuum cover is adjusted, the valve is opened to reduce the pressure or the vacuum pump is operated to increase the pressure, so that the absolute pressure value in each vacuum cover is stabilized at the preset value; then the central control module sends the data to the display module, and the test personnel can observe the real-time situation of the aluminum liquid hydrogen measurement process according to the display results of the display module. If there is a pressure abnormality, the test personnel can also type in instructions to change the operation of the vacuum pump and vacuum valve in the aluminum liquid hydrogen measurement device through the control module;

[0043] The above data transmission and the transmission of commands typed by the control personnel are all realized by the wireless module. Zigbee wireless transmission technology or WiFi wireless network transmission technology can be used for short-distance wireless transmission to avoid the impact of data transmission line clutter on the experiment and ensure the real-time validity of the data.
