Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present invention.
FIG. 1 is an overall perspective view of a self-cleaning filter apparatus according to one embodiment of the present invention; FIG. 2 is an exploded view of a slag scraping mechanism according to an embodiment of the present invention; FIG. 3 is a schematic illustration of a slag scraping mechanism of a self-cleaning filter apparatus according to one embodiment of the invention; fig. 4 is an enlarged view of a slag scraping mechanism of the self-cleaning type filtering apparatus according to an embodiment of the present invention in an opened state. In fig. 1 to 4, the self-cleaning filter apparatus may include a cylindrical filter passage 01, a filter screen surface 02, a liquid injection port 03, a residue precipitation port 04, a liquid outlet 05, and a residue scraping mechanism 06. Wherein the filter screen surface 02 can be arranged coaxially with the cylindrical filter channel 01. The liquid injection port 03 can be arranged at the top of the cylindrical filtering channel 01 and positioned in the filtering screen surface 02, and the liquid injection port 03 can be used for injecting liquid to be filtered. The liquid injection port 03 can be arranged at the top of the cylindrical filtering channel 01 and positioned in the filtering screen surface 02 for injecting liquid to be filtered. The filter residue settling port 04 may be provided inside the cylindrical filter channel 01 for settling and removing the filtered filter residue. The liquid outlet 05 may be disposed at the bottom of the cylindrical filtering channel 01 and outside the filtering screen 02, for discharging the filtered liquid. The slag scraping mechanism 06 can be arranged inside the filter screen surface 02. The schematic structure of the slag scraping mechanism 06 can be as shown in fig. 3. In this fig. 3, the slag scraping mechanism 06 may include a slag scraping main shaft 06a and a slag scraping brush 06b. Wherein, the slag scraping brush 06b may be hinged to the side of the slag scraping main shaft 06a, and the hinged hinge shaft is parallel to the slag scraping main shaft 06 a. The side of the scraper spindle 06a may be provided with a stop such that the range of rotation angle of the hinge is in the interval 0 to 90 degrees on the radial line side of the scraper spindle 06 a.
When the self-cleaning filter apparatus shown in fig. 1 to 3 is operated, if a slag scraping operation is required, the slag scraping mechanism 06 may be rotated counterclockwise (or clockwise) in a plan view, for example, so that the slag scraping brush can be rotated to a position parallel to a radial line of the slag scraping main shaft 06, and a schematic view of the slag scraping mechanism 06 after being opened is shown in fig. 4, thereby performing a slag scraping operation on the filtering screen 02; the scraping mechanism 06 may be rotated in the reverse direction (clockwise rotation) if the live scraping operation has ended without currently performing the scraping operation. In the case where the slag scraping mechanism rotates clockwise in a plan view, for example, the slag scraping brush 06b can rotate to a position perpendicular to the radial line of the slag scraping main shaft, so that the slag scraping brush 06b is accommodated on the slag scraping main shaft 06a, and correspondingly, a schematic view of the accommodated slag scraping brush 06b is shown in fig. 3. Through this scrape sediment mechanism 06 for scrape sediment brush 06b can accomodate on scraping sediment main shaft 06a when need not carry out the sediment operation of scraping, and do not contact with filter screen face 02, thereby overcome the technical defect that the area of contact of filter screen face 02 and liquid reduces that leads to because of scraping sediment brush 06b among the prior art.
In addition, in order to facilitate the slag scraping brush 06b to cover the whole filtering screen surface 02 and simultaneously to avoid the technical problem of unbalanced driving force of the motor caused by the concentration of the slag scraping brush 06b at the same position on the circumference of the cylindrical filtering passage 01, as shown in fig. 3, the slag scraping brush 06b may be arranged on the side wall of the slag scraping main shaft 06a in a staggered manner.
In this embodiment, further, in order to facilitate the accommodation of the slag scraping brush 06b on the slag scraping main shaft 06a, as shown in fig. 5, the slag scraping main shaft 06a may be provided with an accommodation groove 06c. The slag scraping brush 06b may be disposed in the receiving groove 06c, and the hinge shaft 06d of the slag scraping brush 06b may be located near a sidewall of the receiving groove 06c, thereby enabling the sidewall to serve as a stopper plate to limit a rotation angle of the slag scraping brush 06b. Further, in order to facilitate the slag scraping brush 06b to be received in time when the slag scraping operation is stopped, a torsion spring (not shown) may be provided on the hinge shaft 06 d. The torsion spring is used for limiting the rotation angle of the slag scraping brush 06b on the slag scraping main shaft 06a, and the larger the angle of the slag scraping main shaft 06a which is rotated out of the slag scraping main shaft 06a is, the larger the force provided by the torsion spring for accommodating the slag scraping main shaft 06a is, so that the slag scraping mechanism 06 can be timely accommodated back on the slag scraping main shaft 06a under the condition that the slag scraping mechanism 06 rotates or stops rotating along the direction of non-slag scraping operation.
In this embodiment, for the device for driving the slag scraping mechanism 06 to rotate, various manners known to those skilled in the art may be used, including but not limited to a manual rocker, a servo motor, etc. In a preferred example of the present invention, the filtering apparatus may include a driving motor, which may be connected to the slag scraping main shaft 06a to drive the slag scraping main shaft 06a to rotate or stop.
In one embodiment of the present invention, considering that in the case where the filtering apparatus is in filtering operation, since the liquid in the cylindrical filtering passage 01 is injected from top to bottom and the water pressure required for the filtering screen 02 is from inside to outside, at this time, in order to increase the water pressure inside to outside of the filtering screen 02, thereby improving the filtering effect, the slag scraping mechanism 06 may further include a flow rate adjusting plate 06e. As shown in fig. 3, the flow rate adjusting plate 06e may be disposed obliquely to a side of the slag scraping main shaft 06a, and a direction of a line connecting a high point and a low point of the flow rate adjusting plate 06e may be opposite to a direction in which the slag scraping main shaft 06a rotates when performing a slag scraping operation. When the filtering device performs filtering operation, the residue scraping main shaft 06a can rotate clockwise, so that liquid is pushed to the periphery from the center of the cylindrical filtering channel 01, the water pressure on the filtering screen surface 02 is improved, and the purpose of improving the filtering effect is achieved. On the other hand, when the slag scraping operation is performed, since the connecting line direction of the high point and the low point of the flow rate adjusting plate 06e is opposite to the rotating direction when the slag scraping main shaft 06a performs the slag scraping operation, the downward water pressure of the liquid is accelerated under the condition that the slag scraping main shaft 06a rotates anticlockwise, so that the falling of the particulate matters on the filter screen surface 02 in the slag scraping operation is accelerated, and the slag scraping efficiency is improved. In addition, in the prior art, since the driving motor is generally in a stop state in the process of performing the filtering operation by the filtering device, and is restarted when the slag scraping is required, the repeated start and stop can cause the reduction of the service life of the driving motor. And because the water tightness of the equipment is problematic, if the rotor of the driving motor does not rotate for a long time after water inflow, the situation of jamming easily occurs, therefore, the driving motor in the filtering equipment provided by the invention is in a state of continuously working no matter in the filtering operation or the slag scraping operation, and the working mode obviously can overcome the technical problems and prolong the service life of the driving motor.
On the other hand, the present invention also provides a control method, which may be used to control the filtering apparatus as shown in fig. 1 to 5, and may include controlling the rotation of the slag scraping spindle in one direction (e.g., counterclockwise) to open the slag scraping brush to complete the slag scraping operation in case that the filtering screen surface needs to perform the slag scraping operation; and under the condition that the filter screen surface does not need to execute slag scraping operation, controlling the slag scraping main shaft to stop rotating.
In this embodiment, in order to achieve a better filtering effect, and at the same time, in order to extend the service life of the driving motor, the control method may further include controlling the slag scraping main shaft to rotate at a high speed in one direction (e.g., counterclockwise) when the slag scraping operation is performed; in the case that the filtering screen surface does not need to perform the slag scraping operation, the slag scraping main shaft is controlled to rotate at a low speed along the other direction (for example, clockwise direction).
In this embodiment, the method for determining whether the screen surface needs cleaning may be in various ways known to those skilled in the art, including, but not limited to, a pressure threshold determination of the liquid, a flow rate threshold determination, and the like. In a preferred example of the present invention, the method of judging the screen surface may be to calculate the difference of the comprehensive condition parameters of the inside and the outside of the screen surface according to formula (1),
X＝NOR(α 1 (x 1 -x 2 ))+NOR(γ 1 (y 1 -y 2 ))， (1)
wherein X is the comprehensive condition parameter difference, alpha 1 Is the flow velocity dependent weight, x 1 X is the flow velocity inside the filter screen surface 2 Gamma is the flow velocity outside the filter screen surface 1 Is the weight of the hydraulic pressure, y 1 For the hydraulic value, y, inside the filter screen surface 2 For the hydraulic value outside the screen surface, NOR is a normalization function. And judging whether the comprehensive condition parameter difference is larger than a preset threshold value, and determining that slag scraping operation can be started under the condition that the comprehensive condition parameter difference is larger than the threshold value.
In yet another aspect, the present invention also provides a computer-readable storage medium storing instructions for being read by a machine to cause the machine to perform a control method as set forth in any one of the above.
According to the technical scheme, the self-cleaning type filtering equipment and the control method thereof provided by the invention have the advantages that the slag scraping brush is hinged with the slag scraping main shaft, so that the slag scraping brush can be opened when slag scraping is needed, and slag scraping operation is realized; when the slag is not required to be scraped, the slag scraping brush can be stored on the slag scraping main shaft, so that the influence on the contact area of the filter screen surface and liquid to be filtered is avoided.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. The technical solution of the invention can be subjected to a plurality of simple variants within the scope of the technical idea of the invention. Including the various specific features being combined in any suitable manner. The various possible combinations of the invention are not described in detail in order to avoid unnecessary repetition. Such simple variations and combinations are likewise to be regarded as being within the scope of the present disclosure.
