Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, and more specifically to an automatic dust removal device. Background Art

[0002] In some occasions where air exchange is required, in order to prevent external dust from entering, an air filter is generally installed on the air exchange air path. After using the air filter for a period of time, dust is easily accumulated, and at this time, a dust removal device is needed to clean the air filter.

[0003] If it is not cleaned in time, too much dust will accumulate on the filter, causing the mesh to be clogged and resulting in poor ventilation. When the equipment is running, it will increase the air flow resistance at the air inlet, reduce the air intake volume, and even damage the equipment. It will also increase the energy consumption of the equipment, which is not conducive to the overall operation of the equipment. Since the filter with too much dust accumulates easily breeds bacteria, it will cause secondary pollution of the air and affect the air quality.

[0004] At present, the dust removal method of the filter of the equipment is to remove it manually for cleaning. During the cleaning process, it is necessary to open the panel and other components of the equipment, and then remove the filter. After cleaning, the filter needs to be reinstalled. This method is time-consuming and labor-intensive, brings inconvenience to users, affects the filtering efficiency of the filter, and affects the cleaning effect.

[0005] Therefore, how to solve the problem of low efficiency in cleaning the filter screen is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0049] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] It should be noted that the directional words such as "upper" and "lower" mentioned below are defined based on the drawings in the specification.

[0051] The core of the utility model is to provide an automatic dust removal device, which can realize automatic dust removal without manual cleaning and replacement of the filter screen, so as to improve the cleaning efficiency and save manpower and material resources.

[0052] Please refer to Figure 1 An automatic dust removal device includes a main frame 1, a dust removal filter 2, a pressure difference component, a spray washing component 3 and a water collection component 4.

[0053] Specifically, the dust filter 2 is tensioned on the main frame 1, and the tension of the dust filter 2 is adjustable. The dust filter 2 is tensioned to prevent dust or other foreign matter in the air from being retained in the folds of the dust filter 2 due to the dust filter 2 being unable to be completely flattened and tightened, thereby affecting the filtering efficiency and the cleaning effect.

[0054] The dust filter 2 has a windward side and a leeward side. The pressure difference component is arranged on the windward side and the leeward side of the dust filter 2. The pressure difference component is connected to the controller. The pressure difference component is set to measure the pressure difference on both sides of the dust filter 2 and feed the data back to the controller. The spray component 3 is movably arranged on the leeward side of the main frame 1. The spray component 3 is used for spraying the dust filter 2. Through the moving spraying of the spray component 3, the dust filter 2 is fully and effectively cleaned. The water collecting component 4 is arranged on the windward side of the main frame 1. The water collecting component 4 is arranged opposite to the spray component 3 so that the water collecting component 4 can collect the waste water sprayed by the spray component 3 on the dust filter 2, and the water collecting component 4 moves synchronously with the spray component 3 to collect the waste water sprayed on the dust filter 2.

[0055] Among them, the pressure difference components arranged on both sides of the dust filter 2, namely the airflow inlet side (windward side) and the airflow outflow side (leeward side), can be set to feedback the signal of starting the spray component 3 and the water collection component 4 to the controller within a certain pressure difference range, or enable the controller to automatically start the spray component 3 and the water collection component 4 according to a preset time period. There is no restriction on this, as long as the above-mentioned technical effect can be achieved.

[0056] The automatic dust removal device arranged in the above manner, when in use, controls the pressure difference component to open through the controller. When the pressure difference component measures that the pressure difference between the two sides of the dust filter 2 is within the preset pressure difference value range of the pressure difference component, it is determined that the dust filter 2 is blocked, and the pressure difference component sends the signal to the controller. The controller controls the operation of the spray cleaning component 3 and the water collection component 4 to realize the cleaning of the dust filter 2 and the collection of the waste water after cleaning. The dust filter 2 can be effectively cleaned without disassembling the dust filter 2 to improve the cleaning efficiency. Moreover, the entire cleaning and dust removal process does not require human control, which can save manpower.

[0057] In the above embodiment, the main frame 1 is a rectangular structure, and the main frame 1 is provided with a first movable component 5 and a second movable component 6 both connected to the controller. The first movable component 5 is arranged on the leeward side of the main frame 1, and the second movable component 6 is arranged on the windward side of the main frame 1. The spray component 3 is arranged on the first movable component 5, and the spray component 3 is moved along the height and width directions of the main frame 1 through the first movable component 5. The water collecting component 4 is arranged on the second movable component 6, and the water collecting component 4 is moved along the width direction of the main frame 1 through the second movable component 6. The water collecting component 4 extends along the height direction of the main frame 1 to correspond to the movement of the spray component 3 in the height direction of the main frame 1.

[0058] It should be noted that when the controller receives the signal sent by the pressure difference component to start the spray component 3 and the water collecting component 4, the controller controls the first movable component 5 and the second movable component 6 to run synchronously, so as to drive the spray component 3 on the first movable component 5 to move along the width direction of the main frame 1, and at the same time drive the water collecting component 4 on the second movable component 6 to move synchronously along the width direction of the main frame 1, so as to realize the cleaning of the dust filter 2 by the spray component 3 in the lateral direction. When the first movable component 5 drives the spray component 3 to move in the height direction of the main frame 1, the cleaning of the dust filter 2 in the height direction can be realized. The water collecting component 4 is extended along the height direction of the main frame 1. As long as the water collecting component 4 and the spray component 3 move synchronously in the lateral direction, the effective collection of waste water can be realized.

[0059] Among them, in this embodiment, the main frame 1 is a rectangular structure, but in practical applications, there is no limitation to this, as long as the above-mentioned technical effects can be achieved.

[0060] Please refer to Figure 2 The first moving component 5 includes a first guide rail 51, a transverse connecting rod 52, a first stepper motor 53, a second guide rail 54 and a second stepper motor 55. The first guide rail 51 is arranged on the borders on both sides of the main frame 1 and extends along the height direction of the main frame 1. The top of the main frame 1 is provided with a transverse connecting rod 52 for connecting the first guide rail 51, and one end of the transverse connecting rod 52 is provided with a first stepper motor 53 connected to the controller. The second guide rail 54 extends along the width direction of the main frame 1 and is slidably connected to the first guide rail 51. One end of the second guide rail 54 is provided with a second stepper motor 55 connected to the controller.

[0061] It can be understood that when the controller controls the operation of the first moving component 5, the controller first controls the second stepper motor 55 to operate, so that the slider on the second guide rail 54 moves along the second guide rail 54 to achieve the lateral movement of the slider on the second guide rail 54, and then controls the first stepper motor 53 to operate, so that the slider on the first guide rail 51 moves along the first guide rail 51 to achieve the longitudinal movement of the slider on the first guide rail 51, thereby driving the longitudinal movement of the second guide rail 54 on the slider on the first guide rail 51, and through the setting of the transverse connecting rod 52, the first guide rails 51 on both sides of the main frame 1 can be synchronously driven by the first stepper motor 53 to move longitudinally.

[0062] Furthermore, the spray assembly 3 is slidably connected to the second guide rail 54, and a first proximity switch 7 connected to the controller is provided at a position of the first guide rail 51 near the top of the main frame 1, and a second proximity switch 8 connected to the controller is provided at one end of the second guide rail 54, and the second proximity switch 8 is arranged at one end near the first proximity switch 7.

[0063] It should be noted that a first proximity switch 7 is provided at the top of the first guide rail 51 near the edge of the dust filter 2. When the slider of the first guide rail 51 moves to this position, the first proximity switch 7 senses and works, and the position at this time is the starting position of the Y axis. A second proximity switch 8 is provided at the second guide rail 54 near the second stepper motor 55 and the edge of the dust filter 2. When the slider of the second guide rail 54 moves to this position, the second proximity switch 8 senses and works, and the position at this time is the starting position of the X axis.

[0064] Please refer to Figure 3 The second moving component 6 includes a third guide rail 61 and a third stepping motor 63. Two third guide rails 61 are provided. Both third guide rails 61 extend along the width direction of the main frame 1. The same end of the two third guide rails 61 is connected by a longitudinal connecting rod 62. One end of the longitudinal connecting rod 62 is provided with a third stepping motor 63 connected to the controller.

[0065] It is understandable that the second stepper motor 55 and the third stepper motor 63 are stepper motors of the same model, and the controller controls the power supply and power off at the same time, that is, synchronous operation. That is, when the controller controls the second stepper motor 55 to operate, it also controls the third stepper motor 63 to operate, so that the sliders on the second guide rail 54 and the third guide rail 61 can move horizontally synchronously. Through the arrangement of the longitudinal connecting rod 62, the sliders on the two third guide rails 61 can be driven by the third stepper motor 63 to move horizontally synchronously.

[0066] On the basis of the above-mentioned embodiment, sliders are provided on the first guide rail 51, the second guide rail 54 and the third guide rail 61, and the sliders are driven by toothed belts. The toothed belts are meshed with rolling bearings. The rolling bearings have an extended axis, one end of the axis is connected to the connecting rod sleeve, and the other end of the axis is connected to the corresponding first stepper motor 53, the second stepper motor 55, and the third stepper motor 63.

[0067] It should be noted that the controller controls the first stepper motor 53, the second stepper motor 55 and the third stepper motor 63 to rotate forward and reverse, so as to drive the axis to rotate forward and reverse, so that the rolling bearing and the axis rotate forward and reverse synchronously, so as to drive the toothed belt on the rolling bearing to move back and forth, thereby driving the slider on the toothed belt to move back and forth synchronously.

[0068] A controller is used to control the actions of the first stepper motor 53, the second stepper motor 55 and the third stepper motor 63 to improve the stability and accuracy of the operation.

[0069] In the above embodiment, the spray component 3 is arranged on the slider of the second guide rail 54, and the water spray port of the spray component 3 is facing the dust filter 2. The water collecting component 4 is arranged on the slider of the third guide rail 61, and the water collecting component 4 is arranged towards the water spray port.

[0070] It can be understood that the controller simultaneously controls the operation of the second stepper motor 55 and the third stepper motor 63, so that the slider on the second guide rail 54 moves laterally along the second guide rail 54 to realize the lateral movement of the spray assembly 3, so that the water of the spray assembly 3 is sprayed laterally to the dust filter 2, and the slider on the third guide rail 61 moves laterally along the third guide rail 61 to realize the synchronous lateral movement of the water collecting assembly 4, so that the water collecting assembly 4 collects the waste water, and then controls the operation of the first stepper motor 53 to make the slider on the first guide rail 51 move along the first guide rail 51 to realize the longitudinal movement of the second guide rail 54 on the first guide rail 51, thereby driving the longitudinal movement of the spray assembly 3 on the second guide rail 54, so that the water of the spray assembly 3 is sprayed longitudinally to the dust filter 2, at this time, the third stepper motor 63 does not run, so the water collecting assembly 4 can collect the waste water.

[0071] In this embodiment, the water-spraying component of the flushing assembly is a flushing nozzle, which is not limited.

[0072] As a preferred embodiment, the water collecting assembly 4 includes a water baffle plate 41 and a water collecting trough 42. The water baffle plate 41 is arranged on the slider of the third guide rail 61 and extends along the height direction of the main frame 1. The water collecting trough 42 is arranged at the bottom of the water baffle plate 41 and extends along the width direction of the main frame 1. A drain pipe 43 is provided at one end of the water collecting trough 42, and the bottom of the water collecting trough 42 has an inclination so that the waste water collected in the water collecting trough 42 can be discharged from the drain pipe 43.

[0073] It should be noted that when the controller controls the third stepper motor 63 to operate, the water baffle plate 41 moves laterally synchronously with the slider on the third guide rail 61 to collect waste water. The waste water collected by the water baffle plate 41 flows downward along the height direction of the water baffle plate 41 into the water collecting trough 42, and is finally discharged through the drain pipe 43 at one end of the water collecting trough 42.

[0074] Among them, the two sides of the water baffle 41 are inclined, which can not only guide the wind to reduce the flow resistance of the airflow, but also prevent the splashing of flushing water. The water collection tank 42 is an inclined chassis, which is more conducive to the outflow of water and dirt. In practical applications, there is no restriction on this, as long as the above-mentioned technical effects can be achieved.

[0075] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 The main frame 1 includes an upper plate 11, a lower plate 12, a left plate 13 and a right plate 14. A plurality of adjustment holes 15 are provided at the bottom of the upper plate 11 and the top of the lower plate 12 to adjust the tension of the dust filter 2 on the main frame 1. The adjustment holes 15 are arranged along the length direction of the upper plate 11 and the lower plate 12. The lower plate 12 is also provided with a plurality of drainage holes 16 that are connected to the water collecting tank 42.

[0076] It is understandable that the sheet metal flanges of the upper side plate 11, the left side plate 13, and the right side plate 14 of the main frame 1 are all oriented in the direction of the airflow, and the sheet metal flanges of the lower side plate 12 are oriented in the countercurrent direction of the airflow. The water collecting trough 42 is installed on the inner side of the sheet metal of the lower side plate 12, and the drainage hole 16 and the dust filter 2 are arranged directly above the water collecting trough 42, which is more conducive to the water collecting trough 42 to receive water. The lower side of the upper side plate 11 of the main frame 1 and the upper side of the lower side plate 12 are both provided with adjustment holes 15. The adjustment holes 15 are waist-shaped long holes, so that when the filter adjustment side plate 17 is adjusted, the dust filter 2 can be moved within a certain range, and finally the dust filter 2 is laid flat and tightened, and then the bolts in the adjustment hole 15 are locked to make it completely fixed, and finally the filter adjustment side plate 17 is used to cover the adjustment gap. The filter adjustment side plate 17 is a U-shaped plate. In actual application, there is no restriction on this, as long as the above-mentioned technical effect can be achieved.

[0077] Compared with the existing dust removal device, which may require water collecting tanks 42 on both sides, the structure is relatively complex, the installation is cumbersome, and the cost is high. However, the present application only needs one water collecting tank 42, which has a relatively simple structure, is easy to install, and has a low cost.

[0078] In this embodiment, the dust filter 2 is made of stainless steel, the upper plate 11, the lower plate 12, the left plate 13 and the right plate 14 are all hot-dip galvanized steel plates, and the first guide rail 51, the second guide rail 54 and the third guide rail 61 are all made of aluminum, which is not easy to corrode and is durable.

[0079] Among them, in this embodiment, the dust filter 2 is made of stainless steel, the upper plate 11, the lower plate 12, the left plate 13 and the right plate 14 are all hot-dip galvanized steel plates, the first guide rail 51, the second guide rail 54 and the third guide rail 61 are all made of aluminum, but in actual applications, there is no restriction on the material of each component, and it can be adjusted according to actual conditions.

[0080] In the above embodiment, the spray assembly 3 is connected to the flushing pipeline, and the flushing pipeline is provided with a pre-filter device, a booster pump and a solenoid valve, and the pre-filter device and the booster pump are both connected to the controller.

[0081] It should be noted that the flushing pipeline of the flushing nozzle is equipped with several devices, which are: pre-filter device, diaphragm booster pump, drip pump (equipped with professional cleaning agent), solenoid valve. In practical applications, other devices can also be set, and there is no restriction on this.

[0082] In summary, the automatic dust removal device provided by the utility model manually debugs and sets each stepper motor before starting the automatic mode: first run the third stepper motor 63 (second stepper motor 55) to the starting position of the X-axis, then run the third stepper motor 63 (second stepper motor 55) to the end position of the first range segment of the dust removal filter 2, record the number of running steps of the third stepper motor 63 (second stepper motor 55), assuming it is 100 steps, when the flushing nozzle range is 20 steps, set the dust removal filter 2 to run 5 segments in the first range segment; run the third stepper motor 63 (second stepper motor 55) to the starting position of the second range segment of the dust removal filter 2, record the number of steps at the current starting position, and run the third stepper motor 63 (second stepper motor 55). The second stepper motor 55) passes through the dust filter 2 and reaches the end position of the second range segment. The number of running steps of the third stepper motor 63 (the second stepper motor 55) is recorded. It is assumed to be 100 steps. When the flushing nozzle range is 20 steps, the dust filter 2 is set to run 5 segments in the second range segment. The first stepper motor 53 is run to the starting position of the Y axis, and then the first stepper motor 53 is run to the end position of the Y axis range segment of the filter (that is, the edge position of the dust filter), and the number of running steps of the first stepper motor 53 is recorded and the number of running steps of the Y axis is set. After power failure, the center of the flushing nozzle and the center of the water baffle 41 are manually moved to the center position of the junction of the dust filter. At this time, the debugging setting is completed, and the equipment automatically returns to the center position of the junction of the filter after one operation.

[0083] The device of the present invention can be operated fully automatically, does not require manual operation, and does not require replacement of the filter screen, thus greatly saving manpower and material resources.

[0084] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0085] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
