Description

Vacuum recovery device {VACUUM RECOVERY APPARATUS}

The present invention relates to a vacuum recovery device.

In general, industrial sites that manufacture ships and heavy equipment with relatively large factories, such as shipyards and heavy industry plants, go through assembly and fabrication processes, and process, cut, weld or grind materials such as iron, rubber, and synthetic resins. The upper body will be manufactured. In particular, the surface of the steel structure is rust and foreign substances are generated, if not removed, corrosion or paintability is significantly reduced, causing a significant impact on the quality and life of the steel structure. In order to prevent this from happening, Blasting is an essential process. At this time, by using the projection device during the Blasting process, by burning the (Grit / Shot ball) on the surface of the steel structure to remove rust and foreign matter. At this time, the combustion materials (Grit / Shot balls) projected on the surface of the steel structure through the projection device are accumulated scattered widely on the shop floor. In addition, by-products such as grit (Grit), dust, dust, foreign matters are bound to occur. The Grit / Shot ball and foreign matters need a device to recover it for the next work or reuse. This is called Vaccum Recovery.

Therefore, a vacuum recovery device is provided in an industrial site such as a shipyard, so that a burner (Grit / Shot ball), dirt or by-products generated in a machining shop, a blasting room, a painting room, etc. Various wastes, for example, dry dust or foreign matter, various dusts, metal chips, suspending substances, etc. are collected by suction by a vacuum negative pressure (wind pressure) of a blower, and then processed. In particular, since the grit having a constant size is scattered on the floor of the work site, the grit having a constant size can be efficiently recovered with the present recovery device. However, steel balls and iron dust, which are finer than the filters in the vacuum recovery device and float in the air, enter the blower, causing wear and damage to the blower inner casing and rotor. Here, when the blower casing is worn, the vacuum pressure is lowered and the ability to recover grit 4 is lowered. In addition, if foreign matter gets stuck in the rotor, the blower may stop, causing failure. The blower is not only deteriorating the work environment due to the failure of the blower, but also a blower is an expensive product, which may shorten the lifespan or cost a lot of maintenance due to repair and failure.

In addition, irrespective of the amount of by-products to be recovered, the blower generates a certain amount of air and a vacuum, which causes inefficient energy consumption and the blower to reduce the life of the vacuum recovery device, resulting in a decrease in recovery efficiency. Thus, there is a need for dynamic control of the blower that immediately responds to a variety of conditions beyond drive and non-drive of the blower.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is only an example and the present invention is not limited thereto.

In describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or an operator. Therefore, the definition should be made based on the contents throughout the specification.

The technical spirit of the present invention is determined by the claims, and the following embodiments are merely means for efficiently explaining the technical spirit of the present invention to those skilled in the art.

1 is a view showing the structure of a vacuum recovery apparatus 100 according to an embodiment of the present invention.

Referring to FIG. 1, the vacuum recovery apparatus 100 according to the present embodiment includes a dust collecting tank 110, a cyclone tank 120, a dust collecting tank 130, a blower 140, and a purification tank 150. Each component may be connected to each other by the transfer pipe (121, 131, 141, 151). An external suction 1 may be moved through the transfer pipes 121, 131, 141, and 151, and a dust collecting tank 110 may be introduced into the vacuum recovery device 100 for the first time. And (111). Furthermore, the suction pipe 111 is formed of a flexible pipe, so that the user can be bent and moved to the suction point of the suction 1. The dust collecting tank 110 may be collected by filtering the suction 1 suctioned through the suction pipe 111 from the outside. In this case, the suction 1 may refer to grit, foreign matter, etc. generated after performing a blasting operation, and the foreign matter may include a shot ball 1b discharged for peeling and a by-product 1a formed by peeling. have. For continuous blasting operation and the like, first, the shotball 1b and the by-product 1a are sucked and separated from each other so that the shotball 1b can be reused.

In the dust collecting tank 110 in which the suction 1 is moved by suction for reuse of the short ball 1b, the heavy one by the weight to separate the shot ball 1b and the by-product 1a is secondary. The lightball can be moved down and the lighter one can be moved upwardly to separate the shotball 1b and the by-product 1a. For example, when the short ball 1b is made of metal, the shot ball 1b may be dropped downward and the by-product 1a may move upward. The by-product 1b may be formed of a metal, but may include foreign substances such as welding dregs formed during the welding process.

The by-product 1a moved upwards may be moved to the dust collection tank 130 through the transfer pipe 131. In the dust collection tank 130, the by-product 1a may be collected and air may be discharged to the outside by blowing the blower 140. Here, the air discharged to the outside may be purified and discharged in the process of passing through the purification tank 150 to a predetermined level.

On the other hand, although not shown in Figure 1, the vacuum recovery apparatus 100 during the driving of the control unit and the blower 140 for controlling the rotational speed of the rotating fan (rotor) so that the blower 140 is driven and blown The display unit may further include an air volume, a vacuum degree, a temperature of the blower 140, a recovery amount, and a power consumption.

On the other hand, when the fan (rotor) is operated by the rotational force of the motor to drive the blower 140, the means for driving the suction force in the vacuum recovery apparatus 100 is the fan (rotor) In addition, another fan (rotor) for separately adjusting the above-described vacuum degree may be further included to adjust the vacuum degree. In addition, unless another configuration for adjusting the degree of vacuum is provided separately, one fan (rotor) may rotate to generate wind power to suck the intake material 1 in the process of sucking outside air, but the degree of vacuum When further equipped with a means such as a separate fan (rotor) to control the, it is possible to implement the optimum suction power and energy consumption by various combinations by adjusting the vacuum and wind power. The optimal suction force and energy consumption are due to a preset value, which means performance that converges to the target value.

The controller may drive the blower 140 based on a preset value displayed on the display and input. For example, the blower 140 may be driven at a rotation speed capable of satisfying a recovery amount input as a preset value. In addition, when the recovery amount is satisfied, as a next priority, it can be operated at a rotational speed that maintains the recovery amount but satisfies lower power consumption. Specifically, it may be controlled to satisfy the preset value in the amount of recovery and power consumption through various combinations of the air flow rate and the vacuum degree which are fluctuated together with the change in the rotation speed. More specifically, it will be described later with reference to FIGS. 2 and 7.

2 is a conceptual diagram illustrating a process of controlling the blower 140 based on a result calculated in consideration of air volume, vacuum degree, temperature, power consumption amount, and the like according to an embodiment of the present invention.

Referring to FIG. 2, the vacuum recovery apparatus 100 may be operated by the power of the blower 140. First, when the blower 140 is driven 10, by the at least one sensor included in the vacuum recovery apparatus 100, the air volume, the degree of vacuum, the blower generated by the blower 140 in the vacuum recovery apparatus 100. At least one or more of the temperature of 140 and power consumption and recovery amount may be measured. The measured measurement value M may be displayed by a display unit not shown. The measured value M may be compared with the preset value P. Here, the preset value P may mean a target value. For example, the preset value P may be a pre-input amount of inhalation of 3 to 5 tons of byproducts per hour. Therefore, the measured value M may be compared with the preset value P. In this process, a difference may occur between the actual measured value M and the preset value P which is a target value.

The difference may be compensated based on the preset value P. The compensation means that the blower 140 is operated to satisfy at least one condition of the preset value P. Here, the preset value P may include, for example, air volume, vacuum degree, temperature of the blower 140, and the like, and may be controlled to be compensated by changing one or more of these conditions.

Specifically, the control may have a priority. For example, it is possible to rotate at a rotational speed at which less power consumption is required while satisfying the recovery amount first and maintaining the satisfied recovery amount. For example, when the recovery amount of the preset value P is 3 tons per hour, the case where the fan (rotor) rotational speed of the blower 140 is low among conditions satisfying the recovery amount of 3 tons is adopted. The controller may control the blower 140.

Of course, the priority may be changed, but according to the result of the calculation 20 obtained by comparing the preset value P with the measured value M, maintaining the recovery amount as described above, but reducing the power consumption. There may be an example.

3 is a conceptual diagram illustrating a process in which the blower 140 is switched to the standby mode when the recovery amount of the by-product 1a according to an embodiment of the present invention is recovered below a predetermined amount.

Referring to FIG. 3, the vacuum recovery apparatus 100 may be operated by the power of the blower 140. First, when the blower 140 is driven 10, at least one or more sensors included in the vacuum recovery apparatus 100 may generate the air volume, the degree of vacuum, and the blower generated by the blower 140 in the vacuum recovery apparatus 100. At least one or more of the temperature of 140) and the amount of power consumption and recovery can be measured. The measured measurement value M may be displayed by a display unit not shown. The measured value M may be compared with the preset value P. Here, the preset value P may mean a target value.

Here, a difference may occur between the measured value M and the preset value P, and the difference may be compensated based on the preset value P. The compensation means that the blower 140 is operated to satisfy at least one condition of the preset value P. Here, since the preset value P may include, for example, air volume, vacuum degree, and temperature of the blower 140, one or more of these conditions may be changed to control the compensation.

However, as an example, when the preset value P is a recovery amount, when the by-product 1a to be recovered does not reach the preset value P, the preset value is satisfied by a combination of conditions such as air flow rate and vacuum degree. It can be determined that it can not be switched to the standby mode (31). That is, when the suction 1 to be recovered is generated by less than a predetermined amount, the blower 140 may be operated at a low rotational speed. Specifically, the standby mode 31 is not a state in which the operation of the blower 140 is stopped, but the blower 140 continuously maintains the driving state at a predetermined rotational speed. The rotational speed may be increased and controlled by the controller to satisfy a condition such as a recovery amount or power consumption amount according to the predetermined priority as illustrated with reference to FIG. 2.

That is, when the amount of the by-product 1a to be recovered is not generated by a predetermined amount, the rotation speed of the blower 140 may be lowered to reduce the power consumption. For example, it may be rotated at 400rpm when the lowest rotational speed of the operating speed is 800rpm.

Furthermore, after the standby mode 31, the blower 140 may be in an operation stop state (not displayed). The movable stop state is a state in which the fan rotation of the blower 140 is stopped, and means a state in which the vacuum degree or the wind power does not act by the power. This operation stop state may be performed after the standby mode 31, or may be immediately performed by omitting the standby mode 31. This process may be selectively determined by preset information.

4 is a conceptual diagram illustrating a process of controlling the blower 140 based only on the air volume information according to the first embodiment of the present invention.

Referring to FIG. 4, at least one sensor included in the vacuum recovery apparatus 100 includes a sensor for detecting the air volume, and the measured value A2 of the air volume measured by the sensor is compared with the preset value A1. Through the comparison, the blower 140 may calculate information to be driven. Of course, the preset value A1 may include air volume information comparable to the measured value A2 of the air volume. In addition, in order to adjust the recovery amount by a target value, for example, when the air volume included in the preset value A1 is larger than the air volume included in the measured value A2, the air volume by the blower 140 is reduced, When the air volume included in the preset value A1 is smaller than the air volume included in the measured value A2, the air volume by the blower 140 may be increased.

Of course, through the comparison of the air volume of the preset value (A1) and the measured value (A2) as described above, it is possible to satisfy the recovery amount by increasing or decreasing the air volume, but also to increase and decrease the conditions such as vacuum degree to satisfy the recovery amount and power consumption. Can be. Therefore, after the first driving 10, the number of rotations of the blower 140 to be driven is calculated by comparing the measured value A2 with the preset value A1, and the blower 140 is driven according to the calculation result. (30a) can be performed.

5 is a conceptual diagram illustrating a process of controlling the blower 140 based only on the blower 140 temperature information according to the second embodiment of the present invention.

Referring to FIG. 5, at least one sensor included in the vacuum recovery device 100 includes a sensor for sensing the temperature of the blower 140, and the temperature measurement value T2 of the blower 140 measured by the sensor. The information to be driven by the blower 140 may be calculated by comparing with the preset value T1. Of course, the preset value T1 may be compared with the measured value T2 and may include a temperature below a preset temperature that may be determined to be overheating.

In the case of the present embodiment, apart from the target recovery amount, it may be related to the stability of the device to prevent the overheating of the vacuum recovery device 100 and the protection of the equipment from overload. For example, when the temperature of the blower 140 included in the preset value T1 reaches the temperature included in the measured value T2, the rotation speed of the blower 140 decreases, and the preset value T1. When the temperature included in the) is lower than the temperature included in the measured value T2, the controller may determine that the rotation speed of the blower 140 may be further increased.

Therefore, when the temperature included in the preset value T1 is lower than the temperature included in the measured value T2, the air volume is compared by comparing the air volume and the degree of vacuum between the preset value 1 and the measured value A2 as described above. And the degree of vacuum can be increased or decreased to satisfy the recovery amount. Therefore, after the initial driving 10, the number of rotations of the blower 140 to be driven is calculated by comparing the measured value T2 with the preset value T1, and the blower 140 is driven according to the calculation result. 30b can be performed.

6 is a conceptual diagram illustrating a process of controlling the blower 140 based only on the vacuum degree information according to the third embodiment of the present invention.

Referring to FIG. 6, at least one sensor included in the vacuum recovery apparatus 100 includes a sensor for detecting a degree of vacuum, and the measured value V2 of the degree of vacuum measured by the sensor is compared with the preset value V1. Through the comparison, the blower 140 may calculate information to be driven. Of course, the preset value V1 may include vacuum degree information comparable to the measured value V2 of the air volume. In addition, in order to adjust the recovery amount by a target value, for example, when the vacuum degree included in the preset value V1 is higher than the vacuum degree included in the measured value V2, the vacuum degree by the blower 140 is reduced, When the degree of vacuum included in the preset value A1 is lower than the degree of vacuum included in the measured value A2, the degree of vacuum may be controlled by the blower 140 or the like.

Of course, the recovery amount can be satisfied by increasing or decreasing the vacuum degree of the preset value V1 and the measured value V2 as described above, but the recovery amount and power consumption can be satisfied by increasing or decreasing the conditions such as the air volume. Therefore, after the initial driving 10, the number of rotations of the blower 140 to be driven is calculated by comparing the measured value V2 with the preset value V1, and the blower 140 is driven according to the calculation result. 30c can be performed.

7 is a conceptual diagram illustrating a process of controlling the blower 140 based only on power consumption information of the blower 140 according to the fourth embodiment of the present invention.

Referring to FIG. 7, at least one sensor included in the vacuum recovery apparatus 100 includes a sensor for detecting power consumption, and the measured value E2 of the power consumption measured by the sensor is a preset value E1. By comparing with the, the blower 140 may calculate information to be driven. Of course, the preset value E1 may include power consumption information comparable to the measured value E2 of the power consumption amount. Further, in order to adjust the recovery amount by a target value, for example, when the power consumption included in the preset value V1 is higher than the power consumption included in the measured value V2, the power consumed by the blower 140 is Can be controlled to be reduced. Of course, the adjustment of the amount of power may be performed on the premise that the condition of the priority is maintained at the priority transmitted by the controller.

In addition, the power consumption may be adjusted by lowering the rotational speed of the blower 140, but may be increased even under a load such as an overload in which the power consumption does not decrease even when the rotational speed is low.

Accordingly, the blower 140 may be driven (30d) by maintaining a priority state on the priority, but applying a change to a condition such as air volume or vacuum degree.

On the other hand, it can be described in more detail with reference to Figs. 8 and 9 on the basis of the content described above.

8 is a table showing the relationship between the degree of vacuum, air volume and power consumption according to embodiments of the present invention, Figure 9 is a graph showing the relationship between the degree of vacuum, air volume and power consumption according to embodiments of the present invention.

First, referring to FIG. 8, it is possible to know the relationship between the vacuum of the blower 140 and the suction amount of the suction 1. In general, the more the amount of the inputted recovery amount, the higher the degree of vacuum and air volume, and when the amount of recovery is small, the degree of vacuum and the amount of air may decrease. The present invention can perform optimization to reduce power costs in this flow.

Here, the amount of power consumed to maintain the predetermined recovery amount may vary. For example, as illustrated, the overall flow may require a higher power consumption to suck more suction 1 at the rotational speed of the same blower 140. However, since the recovery amount may be as low as the increased power consumption, it can be optimized and operated most efficiently.

For example, when a relatively high power consumption is output, but the suction amount of the suction 1 is small (a vacuum of -40.0 kPa at the rotational speed of the blower 140 at -850 rpm and a vacuum of -26.7 at the rotational speed of the blower 140 at 1150 RPM). comparison between kPa data). That is, the relationship between the degree of vacuum relative to the rotational speed and the amount of suction of the suction 1 may be atypical rather than atypical. Therefore, according to the present invention, after determining the recovery amount of the suction 1 to a fixed value in the above atypical relationship, it is possible to optimize the power consumption required for the rotational speed and the vacuum degree of the blower 140.

The calculation of the optimization value may be performed by inputting a target recovery amount and feeding back a recovery amount for each predetermined time unit, and reaching the target recovery amount based on the feedback recovery amount information per unit time. At this time, when the input recovery amount or recovery per unit time is lower than the actual recovery recovery amount, one or more of the degree of vacuum and the number of revolutions of the blower 140 are adjusted to reach the input recovery amount or recovery per unit time. Can be adjusted.

Here, one or more adjustments may be required even if a higher recovery amount is required since the relationship between the fan rotation speed and the vacuum degree of the blower 140 and the suction object 1 is not made in proportion to the amount of power consumption, as described above. The amount of power consumption may be adjusted to reduce. In this way, when more or less recovery amount is required, based on the power consumption amount, the degree of vacuum or the fan rotation speed of the blower 140 does not tend to increase or decrease proportionally. Adjustments can be made to meet the target recovery or recovery per unit time. Such adjustment may be the “optimization” of the present invention.

In addition, the previously input information may be the above-mentioned recovery amount, but may also be an operation time of the blower 140. The blower 140 may be operated during the input operation time so that the optimization may be performed to reach the input recovery amount. As an example of such optimization, the input time information may be divided into one or more time intervals according to a time flow, and feedback may be provided for each time interval to reach a target recovery amount within the input time.

As a specific example, when the input time is one hour and the time intervals are divided into 10 minute intervals, 10 minutes, 20 minutes, 30 minutes, 40 minutes, and 50 minutes are performed per unit time (in this case, 10 minutes). The amount of feedback may be fed back, and the amount of recovery may be adjusted in a later time interval by reflecting the received amount of collected information. Of course, during the adjustment of the amount of recovery can be optimized to have a lower power consumption environment based on the amount of power consumption. After one hour in the example, which is a previously input time through this process, the vacuum recovery apparatus may be changed to the standby mode described above or the power may be cut off.

Unlike the previous example, when the preset target recovery amount is changed, suction force may be generated based on the changed target recovery amount. In other words. The degree of vacuum and air volume may be determined to achieve the target recovery amount. For example, when the amount of the by-product 1 is large, the recovery amount measured by the sensor may be higher than the target recovery amount. In this case, the target recovery amount, which is a predetermined recovery amount, may be increased to inhale the by-product 1 more quickly. This is a mode that prioritizes productivity among various operation modes of the vacuum recovery device. When the measured recovery amount is higher than the predetermined target recovery amount, the preset target recovery amount is increased by at least the measured recovery amount, thereby increasing the by-product. Recovery of (1) can be achieved.

For example, the target recovery amount among preset input values may be fixed or variable. The target recovery amount is fixed so that the measured recovery amount is operated to reach the target recovery amount, and the target recovery amount can be varied and the recovery amount measured based on the variable target recovery amount is reached. Driving may be referred to as a second mode.

Here, the first mode is a value at which the target recovery amount is fixed. When the target recovery amount is previously input, the blower is driven so that the measured recovery amount reaches the input target recovery amount. Can be. Furthermore, as described above, in the first mode, the suction force determined by the air flow rate and the vacuum degree may vary according to the measured recovery amount, and in response to the measured recovery amount information fed back at a real time, unit time, and intermittent time intervals. can be changed. In addition, the suction force to be changed may be generated by the output combination that consumes a lower power consumption in the output combination of the air flow rate and the recovery amount formed to output the suction force.

Meanwhile, in the second mode, the target recovery amount may vary. The previously input target recovery amount may be increased or decreased and may be changed to a target recovery amount different from the previously entered target recovery amount. Therefore, the amount of air and the degree of vacuum determined by the amount of recovery may be differently formed, and thus the suction force may vary. That is, the second mode may be an operation mode in which suction power is differently established to reach a variable target recovery amount and a variable target recovery amount. For example, when the measured recovery amount is higher or lower than the target recovery amount, the suction force is not generated to satisfy the target recovery amount, but the target recovery amount is changed by a predetermined level to satisfy the changed target recovery amount. Suction force can be established.

The change in the target recovery amount may be changed by one or more conditions such as a predetermined time interval and a predetermined difference between the target recovery amount and the measured recovery amount. Furthermore, as described above, in the first mode, the suction force determined by the air flow rate and the vacuum degree may vary according to the measured recovery amount, and in response to the measured recovery amount information fed back at a real time, unit time, and intermittent time intervals. can be changed. In addition, the suction force to be changed may be generated by the output combination that consumes a lower power consumption in the output combination of the air flow rate and the recovery amount formed to output the suction force.

For example, if the difference between the measured recovery amount and the target recovery amount that is fed back at a predetermined time interval differs by the predetermined amount, the target recovery amount is capped to increase the recovery amount or the target rotation rate is reduced to reduce power consumption. Quantity may be lowered.

Furthermore, after the target recovery amount is adjusted upward, the output combination of the air flow rate and the vacuum degree that enables the blower 140 to operate at the lower power consumption of the output required for the blower 140 operation in the output combination of the air flow rate and the vacuum degree. The blower 140 may be controlled.

Meanwhile, power supplied to the blower 140 may be provided through an inverter (not shown). When power is supplied through the inverter, the voltage and the frequency may be changed, thereby controlling fan rotation of the blower 140. This control can be aimed at reducing the power consumption by using lower power while maintaining the same rotational speed of the fan.

The intervention of the inverter in the power consumption is optional, but the operation of the vacuum recovery device may be performed based on the power consumption input to the preset value. For example, when the upper limit of the determined power consumption amount is input, the blower 140 may be operated based on the recovery amount within the input upper limit power consumption amount.
