Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
At present, in the field of wet shot blasting descaling, solid particles, water and additives are mixed and used, and are centrifugally thrown to the surface of a steel plate or a workpiece through a motor, so that the descaling purpose is achieved. Since industrial water, solid particles, additives and the like are used in the descaling process and are all consumable, automatic detection and addition of the substances are required to ensure the running performance of the equipment. An automated detection and addition process for solid particles is described herein.
At present, the detection and addition of solid particles inside the device are carried out by the following methods:
1. According to practical working experience, 50 kg of solid particles are added to the equipment quantitatively according to working hours, for example, the equipment works for one hour. Because the consumption of solid particles is dynamic and not a fixed value when the device is in operation, and the difference between the consumption and the addition is increased over a long period of time, the amount of solid particles in the device is too much or too little. When the solid particles are too many, the filtering system not only causes the excessive pressure for separating and screening the solid particles and causes the waste of the solid particles, but also causes the excessive flow resistance after the solid particles are piled up when the working solution is mixed, and the equipment performance and the working efficiency are influenced; when the solid particles are too small, the solid particles after the working solution is mixed are too small, and the efficiency of casting and descaling is affected.
2. The amount of solid particles in the equipment is judged according to the cast turbine load, so that whether the solid particles and the amount need to be added or not is judged. The turbine load is a dynamic value, and the turbine load can be adjusted by the equipment process control; at the same time, the steel grit in the equipment is less, but the load of the turbine is not necessarily lower; the steel grit in the equipment is more, and the turbine current is lower. If the steel grit is added again until the turbine final current is low, the following problems may occur: in fact, the solid particles in the equipment are more, and after the solid particles are added, no help is provided for the current lifting of the turbine; the solid particles in the equipment are very few, and after the solid particles are added, the function of obviously improving the turbine current can not be realized in a short time.
3. When solid particles need to be added, the traditional method is to manually add a certain amount of solid particles into the equipment; or conveying the solid particles into the apparatus through a wringer cage. The manual method has the defect that the labor intensity of workers can be obviously increased due to the frequency of adding solid particles, which is generally about one hour; the disadvantage that hank cage carried is, owing to do not have weighing sensor, directly through the number of turns that hank cage was changeed to estimate the addition, can cause the addition inaccurate, and in addition, partial solid particle is the stereoplasm, and hank cage when starting, if the solid particle that the inside was stored up is too much, very easily causes hank cage card to die, can't play the function of automatic interpolation of steel shot.
4. The quantity of the residual solid particles in the sand adding hopper cannot be known accurately, so that the problem that the solid particles in the sand adding hopper are used and cannot be added into the water tank can be caused; and the operator cannot know exactly when solid particles need to be added to the sand hopper.
Based on the above problems, the embodiment of the invention provides a method, a device and a system for controlling the addition of solid particles, which can monitor and maintain the quantity of the residual solid particles in a water tank in a deviation range, ensure that equipment can well maintain a uniform and stable mixing process of substances such as solid particles, working fluid, additives and the like, ensure the running performance of the equipment and improve the working efficiency of the equipment, and also avoid the waste and loss of the excessive solid particles in the water tank.
For the sake of understanding the present embodiment, first, a method for controlling addition of solid particles disclosed in the present embodiment of the present invention is described in detail, as shown in fig. 1, and the method includes the following specific steps:
Step S102, monitoring liquid level height of a cavity where the solid particles are located and weight data of the cavity under the liquid level height to obtain monitoring data containing the liquid level height and the weight data.
Step S104, based on the monitoring data and the preset relationship between the liquid level and the weight, determining the weight deviation corresponding to the weight data.
And S106, determining solid particle addition parameters according to the weight deviation.
Step S108, starting the solid particle adding device, and controlling the solid particle adding device to add solid particles into the cavity based on the solid particle adding parameters.
In specific implementation, the embodiment of the invention determines the weight deviation condition of the solid particles contained in the current cavity by pre-calculating the relation between the liquid level and the weight and monitoring the liquid level height and the weight data of the cavity where the solid particles are positioned, thereby determining the solid particle adding parameter according to the weight deviation. And controlling the solid particle adding device to add solid particles into the cavity according to the solid particle adding parameters so as to ensure that the weight of the solid particles in the water tank is within a set range.
Based on the above, the method for controlling the addition of the solid particles provided by the embodiment of the invention can monitor and maintain the quantity of the residual solid particles in the cavity within a deviation range, ensure that equipment can well maintain the uniform and stable mixing process of the solid particles, working fluid, additives and other substances, ensure the running performance of the equipment and improve the working efficiency of the equipment, and also avoid the waste and loss of excessive solid particles in a water tank.
Further, on the basis of the above embodiment, the embodiment of the present invention also provides another solid particle addition control method, which mainly describes a process of determining a weight deviation based on a relationship between a liquid level and a weight. The relationship between the liquid level and the weight in the embodiment of the invention is calculated by recording the total weight in the water tank containing the solid particles when different liquid level heights are recorded. The water tank is a cavity in which solid particles are located, and in the embodiment of the invention, the cavity can also comprise a structure such as a water tank and the like which can be weighed.
In one embodiment, the predetermined working fluid is injected into the cavity by throwing solid particles of predetermined weight into the cavity; recording the liquid level height of the working liquid and the weight of the cavity under the liquid level height; based on the liquid level height and the weight, a liquid level to weight relationship is calculated. In the concrete implementation, the weight of solid particles in one liquid level and weight relationship is uniform, and the relationship corresponding to the liquid level and the total weight can be obtained by recording different liquid level height changes and corresponding cavity weight changes, and the corresponding relationship can be determined based on the relationship.
Further, in order to quickly determine the solid particle addition parameters, the embodiment of the invention determines the solid particle addition parameters corresponding to the monitoring data by generating a plurality of relations and judging the monitoring data through the plurality of relations.
In a specific implementation, the preset weight includes a base weight and a plurality of offset weights. According to the embodiment of the invention, a first relation is calculated according to the recorded liquid level height and the weight of the cavity corresponding to the basis weight; calculating a second relation according to the recorded liquid level height and the weight of the cavity corresponding to each deviation weight; the liquid level and weight relationship is constructed based on the first relationship and the second relationship.
Specifically, the offset weight may be set empirically or as required for solid particle addition. For example, a bias weight is determined by setting a minimum amount of solid particles; further, setting an excessive amount of solid particles, and determining another deviation weight; further, the deviation weight may also be set to 0, that is, the relationship between the weight of the cavity body and the liquid level height is recorded, resulting in the relationship between the liquid level and the weight when solid particles are not put in. Wherein the respective deviation weights may be determined by setting deviation ratios for the basis weights, each deviation weight being different in deviation ratio corresponding to the basis weight.
Wherein the weight m1 of the water tank itself and the weight m4 of the suitable solid particles required inside the water tank during operation of the device can be obtained by means of a weight sensor during commissioning of the device. m1 can be considered as a fixed value, m4 is a numerical value running in a certain fluctuation range, when the working fluid is continuously added into the water tank, one data m3 of the height of the fluid in the water tank and the total weight of the water tank can be obtained through the liquid level sensor and the water tank weighing sensor, and can be recorded in the system to be used as a standard for referencing the weight of the water tank when the later equipment runs.
Further, the liquid level versus weight relationship may take various forms, such as a relationship, a ratio relationship, or a graph form. In an embodiment of the invention, the relationship between liquid level and weight is determined by generating a relationship curve. The method comprises the steps of inputting recorded liquid level height and weight into a preset coordinate system to generate a liquid level and weight curve; and determining the data relationship indicated by the liquid level and weight curve as the liquid level and weight relationship.
Further, the monitoring data is judged based on the relation between the liquid level and the weight, so that the addition amount of the solid particles is controlled. In specific implementation, fig. 2 shows a flowchart of another solid particle adding control method according to an embodiment of the present invention, as shown in fig. 2, where the method includes the following steps:
Step S202, monitoring liquid level height of a cavity where the solid particles are located and weight data of the cavity under the liquid level height to obtain monitoring data containing the liquid level height and the weight data.
In concrete implementation, the embodiment of the invention is provided with a liquid level sensor and a weighing sensor in the bottom water tank, wherein the liquid level sensor mainly measures and calculates the working liquid height in the water tank by the depth of the water level; a load cell to detect the total weight in the bottom tank. Since the tank structure is fixed, the weight of the tank itself is constant, so that at different liquid level heights, the total weight is affected by the volume of liquid in the tank and the weight of solid particles.
In step S204, the monitoring data is input into the relationship between the liquid level and the weight.
Step S206, determining the target weight corresponding to the weight data from the first relation of the liquid level and the weight relation based on the liquid level height in the monitoring data.
Step S208, calculating the weight difference between the weight data in the monitoring data and the target weight to obtain the weight deviation corresponding to the weight data.
Corresponding to the relationship between the liquid level and the weight in the embodiment of the invention, the relationship between the liquid level and the weight is in the form of a relationship curve, the monitoring data determined in the embodiment of the invention can be understood as coordinate points with the abscissa being the weight and the ordinate being the liquid level height, and the deviation between the data and the curve is determined by inputting the monitoring data into the relationship between the liquid level and the weight, so that the corresponding weight deviation is known.
In specific implementation, the embodiment of the invention judges whether the solid particles need to be added by determining whether the weight of the solid particles in the current liquid level height meets the standard requirement, namely the use work of equipment. Specifically, if the liquid level height corresponding to the monitoring data is determined from the first relationship (i.e., the relationship between the liquid level and the weight corresponding to the base weight), the target weight corresponding to the first relationship may be automatically determined. Weight deviation of weight data in the monitored data can be calculated based on the target weight.
Further, after the corresponding weight deviation is determined, the state of the current solid particles to be added can be known, and the solid particle adding parameter is determined based on the weight deviation so as to add the solid particles into the cavity. In a specific implementation, the solid particle addition parameter is determined by determining the degree of deviation corresponding to the weight deviation. With specific reference to steps S210-S214 described below.
Step S210, determining the deviation degree corresponding to the weight deviation.
Step S212, determining a target relationship from a plurality of second relationships of the liquid level and the weight relationship according to the deviation degree.
Step S214, determining the working parameters corresponding to the target relationship as solid particle adding parameters.
In one embodiment, the embodiment of the invention determines the solid particle adding parameter by respectively corresponding the working parameters to each second relation, wherein the working parameters of each second relation are different. Wherein the operating parameter may be the amount of single solid particle delivery at different time intervals.
Specifically, by using the second relationship as a criterion for weight deviation, if the weight deviation meets a range corresponding to a certain second relationship, it is possible to determine which state to add the solid particles, and further perform solid particle adding control based on the working parameters corresponding to the current state to add, so that the weight of the solid particles meets the basis weight.
In a specific implementation, a schematic diagram of a relationship between liquid level and weight provided by an embodiment of the present invention is illustrated based on fig. 3, where fig. 3 includes a plurality of relationship curves. Wherein curve 6 is a first relationship; curves 7 and 9 are respectively corresponding second relations of different deviation weights; curve 8 is the liquid level and weight curve of the cavity and working fluid, and is also one of the second relations.
Wherein, if the monitoring data is near the curve 6, the comparison standard of the quantity of the solid particles in the cavity is described; if above curve 7, it is indicated that the amount of solid particles in the tank exceeds the minimum amount, and that it is necessary to add the solid particles immediately; if it is near curve 9 or below curve 9, it is indicated that the amount of solid particles in the tank is too high and that the addition of solid particles needs to be stopped.
Correspondingly, based on the position of the monitoring data in the relation between the liquid level and the weight, determining a corresponding relation curve, and determining the working parameter corresponding to the relation curve as the solid particle adding parameter.
Step S216, starting the solid particle adding device, and controlling the solid particle adding device to add solid particles into the cavity based on the solid particle adding parameter.
In a specific implementation, the solid particle addition parameter includes an addition amount of the solid particles. Wherein, referring to fig. 4, fig. 4 shows a schematic structural diagram of an apparatus comprising a wet shot blasting machine 1, a cavity 2 (such as a water tank) and a solid particle adding apparatus 4. The device also comprises a liquid level sensor 24 and a water tank weighing sensor 23 which are respectively used for monitoring the liquid level height of the cavity where the solid particles 221 are positioned and the weight data of the cavity. In addition, the solid particle adding device comprises a sand adding hopper. In concrete implementation, the working solution enters the water tank from the wet shot blasting machine and is conveyed to the filtering system by the water return pump 5.
Further, when the equipment is in normal operation, the embodiment of the invention also carries out mutual linkage according to the monitored weight data and the throwing amount of the solid particle adding equipment so as to ensure that the weight of the solid particles in the water tank is in a set range. Specifically, in the embodiment of the invention, the gravity sensor is also arranged at the bottom of the sand adding hopper, solid particles are filled in the sand adding hopper, when the system judges that the solid particles need to be added into the water tank, the conveying mechanism in the sand adding hopper is started (the solid particles can be conveyed to the water tank at the bottom through the winch cage or directly opened to flow into the water tank through gravity), and the quantity of the solid particles added into the water tank is controlled through the weighing sensor of the sand adding hopper, so that the aim of overall balance of the system is fulfilled.
Meanwhile, since only the total weight of the sand adding hopper body and the solid particles is contained in the sand adding hopper, the actual weight of the solid particles in the sand adding hopper and the highest or lowest amount can be easily determined. The weight loss in the actual sand adding hopper (namely the quantity of solid particles added into the water tank) is judged by the weight difference delta m before and after single starting.
In a specific implementation, the liquid level sensor detects the height hb of the working liquid 222, and the system automatically matches the obtained weight M (i.e., the weight of the cavity corresponding to the base weight) according to the hb height. Assume that the value between M and the weight M3 obtained by the sink load cell is very close (assuming the deviation is not more than 5%). Preferably, when the equipment is operating normally, according to the running accumulated time, the sand hopper can be set to add solid particles into the water tank at fixed time and fixed quantity, and the particle adding quantity is m5 each time (for example, 50kg of solid particles are added every one hour).
A. When the solid particles in the water tank are obviously increased, the liquid level sensor detects the hb, the system automatically matches the obtained weight M in the database, wherein the weight M is obviously smaller than the weight M3 (more than 5%) detected by the water tank weighing sensor, at the moment, the solid particle adding equipment is controlled to stop adding until the weight deviation between the weight M3 and the weight M is smaller than 5% after the equipment shown in the figure 4 operates for a period of time;
b. when solid particles in the water tank are obviously reduced, the liquid level sensor detects hb, the system automatically matches the weight M obtained according to the database, M is obviously larger than M3 (more than 5%) detected by the weighing sensor of the water tank, at the moment, the system can operate the solid particle adding device until the weight deviation of M3 and M is smaller than 5% after the device is operated for a period of time.
The two execution conditions a and b may be set to control logic for adding the solid particles m4 to the water tank in preference to the timing and the quantitative addition of the sand hopper. Preferably, in order to avoid system out-of-tolerance or deviation caused by other factors, the embodiment of the invention monitors the liquid level height of the cavity where the solid particles are located and the weight data of the cavity under the liquid level height based on a preset time interval; and if the weight deviation corresponding to the monitoring data of the preset continuous times meets the preset deviation value, determining the solid particle adding parameter according to the weight deviation. For example, it may be set for a specific time t1 (e.g., 1 minute) and the system executes the relevant program when it is detected that the solid particles are more than two times or that the solid particles are less than two times.
Further, if the amount of solid particles remaining in the sand hopper is less than a certain amount, for example, 100kg, a system alarm or reminder can be set to remind an operator that a sufficient amount of solid particles need to be added into the sand hopper so as to facilitate the subsequent normal operation.
Further, the solid particle adding apparatus comprises a conveying structure 42, a throwing structure 41 and a weighing structure 43. The conveying structure comprises a stranding cage or a conveying pipeline, the throwing structure comprises a throwing control valve, and the weighing structure comprises a weighing sensor. Wherein, in order to guarantee to add the sand hopper and carry the solid particle smoothly, prevent to lead to the fact in the hank cage screw conveying blade card to die or remaining solid particle time can agglomerate after having long owing to solid particle piles up in the hank cage, will add sand hopper bottom structure and optimize now: 1. the bottom of the sand adding hopper is provided with a pneumatic valve for controlling the supply of solid particles at the bottom of the sand adding hopper; 2. the twisting cage arranged at the bottom is changed into an inclined state, and the discharge hole of the twisting cage faces downwards, so that the main purpose is to reduce the resistance of the twisting cage during conveying.
And the addition control of the solid particles is performed by: starting by controlling a conveying structure of the solid particle adding equipment, and after a preset time, controlling a throwing structure to start according to a preset control frequency; the weight of the solid particles put in is monitored through the weighing structure. When the weight of the solid particles put in meets the solid particle adding quantity indicated by the solid particle adding parameter, the putting structure is controlled to be closed, and after the preset time, the conveying structure is controlled to stop working.
When sand is added each time, the winch cage can be set to slowly rotate first, and then the particle control valve is opened, so that the resistance of transportation of the winch cage slowly rises along with slow filling of solid particles in the winch cage, and the winch cage is prevented from being blocked; when sand adding is stopped each time, the particle control valve is closed, the twisting cage is continuously rotated, and after the residual solid particles in the twisting cage are discharged into the water tank, the twisting cage is stopped, so that no obvious solid particle residues exist in the twisting cage when the machine is stopped each time, the resistance of the next time of starting the twisting cage can be reduced, and accumulation or agglomeration caused by long-time solid particle residues in the twisting cage can be avoided.
Further, since the working fluid in the water tank flows from the operation side to the equipment driving side, the discharge port of the sand adding hopper can be preferably arranged on the operation side of the water tank, so that the steel sand flowing into the water tank can be uniformly deposited to the bottom of the water tank along with the flow of the working fluid, and the steel sand cannot be quickly brought into the water return bin.

In addition, the relationship between the liquid level and the weight is formed in a relationship curve mode, so that monitoring data can be rapidly judged, and the working efficiency is improved.
