All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides a self-induction variable-frequency energy-saving dust removal system for solving the technical problem.

The technical solutions proposed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the self-induction frequency conversion energy-saving dust removing system comprises: a dust removing device and a processing device (not shown in the figure).

In the workshop course of work, produce a large amount of processing waste material easily, for example, in welding process is carried out some products, produce welding waste material and a large amount of dust easily, or at timber cutting mill, fill a large amount of saw-dusts in the mill workshop, perhaps when processing marble into floor tile, need pass through the lathe cutting, cut the marble, polish, if do not carry out reasonable recovery, clearance to processing waste material, not only can make the workshop seem dirty in disorder, still can harm workman's breathing safety even. Therefore, a device is needed to remove and recycle the excess processing waste.

The dust removal device comprises a shell 1, a plurality of air inlets 2, an air outlet 3, a variable-frequency speed-regulating fan 4, a plurality of air channels 5 and a filter 6, wherein the air inlets 2, the air outlet 3 and the variable-frequency speed-regulating fan are arranged in the shell 1; the air inlet 2 is arranged at one end of the air duct 5, the air inlet 2 can be opened and closed, and the other end of the air duct 5 is connected with a variable-frequency speed-regulating fan 4. The variable-frequency speed regulation fan 4 is a fan with a built-in motor being a variable-frequency speed regulation motor, and the negative pressure at the air inlet 2 is controlled by changing the running frequency of the motor in the fan. The filter 6 is arranged at the air outlet 3 and used for filtering dust and paper scraps in air sucked in the air duct 5, and the filter 6 can be detached and cleaned to prevent the filter 6 from being blocked due to excessive dust and paper scraps. Dust collector is used for clearing up rubbish such as dust, scraps of paper, saw-dust on workshop station 7 (workshop station is integrative station in the picture, also can be divided station when dust collector uses), if the waste material that the processing produced still has other usage, the saw-dust can be used for the fuel for example, through set up filter 6 in air exit 3 department, can retrieve the waste material that fills in the workshop.

Although the dust removing device can clean waste materials in a workshop, if one or more air inlets 2 are closed, the negative pressure of other air inlets 2 is enhanced and the suction force is increased because the operating frequency of the variable-frequency speed-regulating fan 4 in the dust removing device is not changed. In order to avoid this kind of condition, among the technical scheme disclosed in this application, still include treatment facility, treatment facility contains control circuit and processing chip, is connected with variable frequency speed governing fan 4 electricity in the dust collector for according to the open and close state of a plurality of air intakes 2, control variable frequency speed governing fan 4's operating power. The treatment device may be located at a suitable location, such as inside the housing 1, and connected to the dust removing means by wire or wirelessly. Through increasing this scheme of treatment facility, can real time control variable frequency speed governing fan 4's running power to the negative pressure of each air intake 2 department is controlled, when partial air intake 2 was closed, the condition of other air intake 2 negative pressures increase suddenly avoided appearing, thereby has promoted the security of using the dust collector in-process, still according to the operating conditions suitable running power who has reduced variable frequency speed governing fan 4, has reduced the consumption of electric energy. The processing equipment directly issues different control instructions through different signals, is a common control logic method in the existing processing equipment, can adopt the processing equipment with the control logic, only needs to set the opening and closing state of the air inlet as an input signal, and can take the fan frequency adjustment as a control instruction.

In one embodiment, if each air inlet 2 is provided with a corresponding air duct 5 and a dust removing device, a plurality of dust removing devices are required, which not only increases the cost, but also is difficult to manage. Therefore, a dust removing device is usually provided corresponding to the plurality of air inlets 2. At this moment, if only be provided with a wind channel 5, seted up a plurality of air intakes 2 with this wind channel 5, can lead to the inside space in wind channel 5 too big, the suction that variable frequency speed governing fan 4 produced is difficult to convey to the desktop of workshop station 7 on to work efficiency has been reduced. Based on this, set up wind channel 5 into multistage structure, one section is the total wind channel 502 that inside was provided with variable frequency speed governing fan 4, another section is many branch wind channels 501 of being connected with total wind channel 502, the one end of every branch wind channel 501 sets up an air intake 2 respectively, every air intake 2 can set up in the place of difference, many branch wind channels 501's the other end is in total wind channel department 502 summary, at this moment, can be under the condition of not changing the distance between variable frequency speed governing fan 4 and each air intake 2, reduce the inside space size in wind channel 5, guaranteed that variable frequency speed governing fan 4's suction can effectively convey to air intake 2 department, the work efficiency of equipment has been guaranteed.

In one embodiment, since a plurality of workshop stations 7 are generally arranged in a workshop environment, and dust on the workshop stations 7 is difficult to clean in real time, in order to facilitate the opening and closing management of each air inlet 2 and clean the desktop of the workshop station 7 in time, the air inlets 2 of the dust removing device are respectively arranged at the corresponding workshop stations 7, for example, at appropriate positions on the desktop of the workshop stations 7. In order to facilitate the use of the air inlet 2, the fixing frame 10 is arranged on the workshop station 7 and used for fixing one end, far away from the air inlet 2, of the branch air duct 501 of the dust removal device, and the branch air duct 501 close to the workshop station 7 is set to be a detachable hose, so that the air inlet 2 can be conveniently moved by a worker, and the flexibility and the cleaning effect of the dust removal device are improved.

Further, since one end of the air duct is a hose, it is difficult to fix the hose on the workshop station 7, so that a corresponding fixing frame 10 can be arranged on the table top of the workshop station 7. The structure of mount 10, support column 8 set up on workshop station 7, the height of support column 8 can freely be adjusted to make things convenient for the staff to use, 8 tops of support column are provided with U-shaped draw-in groove 9, and the internal diameter of U-shaped draw-in groove 9 is less than the hose diameter. Due to the deformability of the hose, the diameter of the hose can be changed correspondingly within a certain range, the inner diameter of the U-shaped clamping groove 9 is slightly smaller than the diameter of the hose, and the hose can be clamped in the U-shaped clamping groove, so that the hose can be fixed more effectively.

In one embodiment, during the use of the dust removing device, sometimes the processing equipment cannot monitor the opening and closing states of the air inlets 2 in real time, and if the processing equipment does not monitor the closing of some of the air inlets 2, the negative pressure at other air inlets 2 will be increased. Based on this, in order to measure and control the negative pressure at the air inlet 2 of the dust removing device more clearly and automatically, a negative pressure sensor 11 is arranged at each air inlet 2 of the dust removing device, and is used for measuring the negative pressure at the air inlet 2 and transmitting related data to the processing equipment. The processing equipment adjusts the running power of the variable-frequency speed-regulating fan 4 in real time according to the negative pressure measured by the negative pressure sensor 11, so as to control the negative pressure at the air inlet 2 of the dust removing device.

Further, because the device in the self-induction frequency conversion energy-saving dust removal system may have this phenomenon of breaking down, for avoiding certain device to break down, and then lead to entire system's practical application, the system can also set up alarm device, and alarm device links to each other with processing equipment, and when detecting that the negative pressure lasts to be less than and predetermines the threshold value, processing equipment control alarm device sends out the police dispatch newspaper to the staff, and the alarm type can be types such as sound, alarm lamp. The alarm device is arranged in the self-induction variable-frequency energy-saving system, so that the condition that the self-induction variable-frequency energy-saving system cannot be used due to the fact that the variable-frequency speed regulation fan 4 in the system breaks down or air leaks from the air inlet 2 can be reduced, and the working efficiency of the system is improved.

In one embodiment, the same idea is that the magnitude of the negative pressure is related to the number of the air inlets in the open state, and in order to prevent the negative pressure at other air inlets 2 from being suddenly increased, an infrared sensor is disposed at each air inlet 2 in the dust removing device, and is used for detecting the open/close state of the air inlet 2 and sending the open/close state to the processing equipment. The processing equipment adjusts the running power of the variable-frequency speed-regulating fan 4 according to the opening and closing quantity of the air inlets 2, so that the negative pressure at the air inlets 2 is stabilized.

As shown in fig. 2, in an embodiment, when the table top of the workshop station 7 is cleaned, the air inlet 2 corresponding to the current workshop station 7 needs to be closed, and a sealing cover 12 may be added to seal the air inlet 2. Further, if the shape of the air inlet 2 is circular, a sealing cover 12 is disposed at the air inlet 2 of the dust removing device, the sealing cover is in threaded engagement with the air inlet 2, so as to increase the sealing performance between the sealing cover 12 and the air inlet 2, and the sealing cover 12 and the air inlet 2 are connected by a connecting line, so as to prevent the removed sealing cover 12 from being lost.

Further, it is desirable that the treatment equipment receives a signal that the air inlet 2 is closed after the air inlet 2 is closed by using the sealing cover 12, so that the whole system is more automated. Based on this, the surface at air intake 2 sets up the interior clamping ring that has the external screw thread, sets up the outer clamping ring that has the internal screw thread at the outer fringe of sealed lid 2 to be equipped with a magnet 13 at the outer clamping ring, be equipped with magnetic inductor 14 at the top of inner clamping ring, so that when outer clamping ring closes fixedly at the inner clamping ring soon, magnetic inductor 14 obtains magnet 13 signal, and sends air intake 2 to the processing equipment and closes the signal, and the operating power of frequency conversion speed governing fan 4 is adjusted according to the quantity of the air intake 2 of opening again to the processing equipment. Magnet 13 is set up to the coupling ring in sealed lid 12 outside, and the coupling ring sets up magnetic inductor 14 in air intake 2, can be faster with the closed signal transmission of air intake 2 to processing equipment for the reaction of variable frequency speed governing fan 4 is more rapid.

Further, in order to prevent the negative pressure of the air inlet 2 from being affected by the suction force at the air inlet 2 after the sealing cover 12 connected to the air inlet 2 by using the connecting line is removed, a connecting member 15 attracted to the magnet 13 is disposed at one end of the air duct 5 close to the air inlet 2, i.e., the branched air duct 501. So that the sealing cover 12 does not hinder the wind flowing at the wind inlet 2 after being removed.
