[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] Please refer to Figure 1-Figure 5 , is a surface water automatic slag removal device 100 described in an embodiment, which includes: an equipment housing 10, an installation cavity 11 is formed inside the equipment housing 10; a filter screen 20, the filter screen 20 is installed inside the installation cavity 11; a driver 30, the driver 30 is arranged outside the equipment housing 10, and the driving shaft of the driver 30 penetrates into the installation cavity 11 and is connected to the filter screen 20 to drive the filter screen 20 to rotate; and a surface water inlet pipe 40, the surface water inlet pipe 40 is connected to the equipment housing 10, and one end of the surface water inlet pipe 40 extends into the installation cavity 11 and is arranged near the lower part of the filter screen 20.

[0022] The equipment housing 10 is the main bearing structure of the surface water automatic slag removal device 100, which is used to load components such as the integrated filter screen 20 and the driver 30 to ensure the stability and reliability of the overall structure.

[0023] For example, the device housing 10 is composed of a support leg assembly and a square housing. The support leg assembly is installed at the bottom of the square housing to support the square housing, so as to facilitate the installation and placement of the whole device on the ground. The support leg assembly and the square housing are made of metal materials such as stainless steel and alloy steel, which are strong and durable, and help to ensure the service life of the surface water automatic slag removal device 100.

[0024] The driver 30 is a power device capable of outputting a rotational driving force, such as a motor, a rotary cylinder, etc. For example, in the present application, the driver 30 adopts a reduction motor, which is specifically a combination of a motor and a reducer, and has the function of reducing speed while increasing torque to ensure the driving efficiency of the filter 20.

[0025] The implementation of the embodiment of the present invention will have the following beneficial effects: the automatic surface water deslagging device 100 of the present scheme is applied in the pre-stage link of surface water input into the water plant. After the surface water is input into the lower area of ​​the filter screen 20 through the surface water inlet pipe 40, the driver 30 drives the filter screen 20 to rotate at a set speed in the installation cavity 11. Wet leaves, weeds, sand and other impurities in the surface water are wet and sticky and adhere to the inner surface of the filter screen 20, thereby being filtered out of the surface water, while the water in the surface water can pass through the filter screen 20 and be filtered and collected, so that the continuously rotating filter screen 20 can realize continuous and automatic deslagging treatment of the inflowing surface water, without the need for human intervention throughout the process, significantly reducing the labor intensity of workers and the operating costs of the water plant, and greatly improving the cleaning and removal efficiency of impurities in the surface water, eliminating potential safety hazards, and ensuring the safe operation of the water plant.

[0026] See also Figure 4 and Figure 5 In one embodiment, the filter screen 20 adopts a C-shaped structure, and the filter screen 20 is provided with a plurality of water filtering holes 21, and the plurality of water filtering holes 21 are arranged in an array along the arc extension direction of the filter screen 20. After such a configuration, the driver 30 drives the filter screen 20 to rotate around the driving shaft of the driver 30 as the rotation center, and the continuously input surface water can continuously contact different parts of the filter screen 20, thereby enabling the filter screen 20 to have the ability to continuously clean and filter impurities in the surface water.

[0027] Furthermore, the filter screen 20 is formed by bending a filter hole plate, and the inner surface of the filter screen 20 is concavely provided with a C-shaped groove 22, which can increase the friction resistance between the inner surface of the filter screen 20 and impurities such as leaves, ensuring that the impurities can effectively adhere to the inner surface of the filter screen 20 and be removed from the surface water for filtration. At the same time, the C-shaped groove 22 also has a storage effect on fine sand particles, that is, it also has a good cleaning effect on fine sand particles.

[0028] It can be understood that the length extension direction of the C-shaped groove 22 is consistent with the width direction of the filter screen 20 .

[0029] Furthermore, the water filter hole 21 is a circular hole, and the diameter of the water filter hole 21 is set to D, D=30mm~50mm. According to the different water quality conditions of the surface water to be treated, the water filter holes 21 with different diameters can be flexibly installed to meet the needs of the water in the surface water passing through the water filter hole 21, and at the same time, the impurities in the surface water are blocked on the inner surface of the filter 20.

[0030] See also Figure 1In another embodiment, the automatic surface water slag removal device 100 further includes a water collection tank 50, which is installed at the bottom of the device housing 10 and vertically opposite to the filter screen 20. The bottom wall of the device housing 10 is provided with a water outlet, which connects the filter screen 20 with the water collection tank 50. Water dripping through the water filter holes 21 passes through the water outlet and finally falls into the water collection tank 50 and is collected.

[0031] The surface water automatic slag removal device 100 also includes a water production pipe 60, one end of which is connected to a water production port 51 provided on the side of the water collection tank 50. The water collected in the water collection tank 50 can be directly sent to a water plant through the water production pipe 60 for filtration and purification, and used as a water source for making tap water.

[0032] Optionally, the water production pipe 60 is inclined so that the filtered surface water can flow to the water plant along the water production pipe 60 under the action of its own weight, eliminating the need to install driving equipment such as pumps, simplifying the overall structure of the surface water automatic slag removal device 100, and reducing costs.

[0033] In one embodiment, a surface water inlet 12 is provided on the side of the device housing 10, and one end of a surface water inlet pipe 40 passes through the surface water inlet 12 and extends to the filter 20. The side wall of the device housing 10 supports and positions the surface water inlet pipe 40, ensuring that the surface water inlet pipe 40 can continuously and reliably deliver external surface water into the filter 20.

[0034] In one embodiment, the surface water automatic slag removal device 100 also includes a cleaning water pipe 90, multiple cleaning nozzles 90a and a solenoid valve 90b. The cleaning water pipe 90 is installed on the equipment housing 10, and one end extends to the upper part of the filter 20. Multiple cleaning nozzles 90a are arranged at intervals on the cleaning water pipe 90 and are located above the filter 20. The nozzle direction of each cleaning nozzle 90a is perpendicular to the filter 20, which helps to improve the spraying efficiency. The solenoid valve 90b is installed in the cleaning water pipe 90.

[0035] In addition, the automatic surface water slag removal device 100 further includes a slag receiving funnel 70 , which is installed inside the installation cavity 11 and arranged below the upper part of the filter screen 20 .

[0036] The part of the filter 20 surface carrying impurities rotates upward and faces the cleaning nozzle 90a, and the cleaning water flows into the cleaning water pipe 90 and is sprayed from the cleaning nozzle 90a toward the filter 20. The water jet can knock down the impurities on the surface of the filter 20 to achieve the cleaning effect on the filter 20, and avoid the clogging of the water filter holes 21 caused by excessive accumulation of impurities, thereby affecting the filtering capacity of the filter 20. The impurities knocked down by the cleaning water fall into the scum receiving funnel 70 below together with the cleaning water.

[0037] Optionally, the solenoid valve 90b may be normally open, so that the cleaning nozzle 90a continuously sprays cleaning water; or, the solenoid valve 90b is opened and closed at a set working interval.

[0038] In one embodiment, the automatic surface water slag removal device 100 further includes a discharge pipe 80, the slag receiving funnel 70 is provided with a discharge port 71, one end of the discharge pipe 80 is connected to the discharge port 71, and the other end of the discharge pipe 80 passes through the side wall of the equipment housing 10 and extends to the outside of the equipment housing 10. The impurities and cleaning water collected in the slag receiving funnel 70 are discharged through the discharge pipe 80 to avoid overflow of the slag receiving funnel 70 and cause equipment damage and environmental pollution. In addition, the discharge pipe 80 can also guide the impurities and cleaning water to a fixed treatment location for convenient centralized disposal.

[0039] The inner surface of the filter 20 is provided with a plurality of impurity anti-skid barrier plates 20a arranged at intervals along the circumferential direction, and the impurity anti-skid barrier plates 20a are bent toward the rotation direction of the filter 20. In order to prevent the intercepted impurities from slipping during the rotation of the C-type filter 20, the C-type groove 22 greatly increases the frictional adhesion of the inner wall of the filter 20, so that leaves and weeds with low density in the water attached to the mesh are not easy to slip off. At the same time, the six impurity anti-skid barrier plates 20a evenly arranged on the inner surface of the filter 20 can maintain a horizontal state even when touching the scum receiving funnel 70, so that the sand particles with higher density in the water can also be brought to the top of the scum receiving funnel 70 and fall into the scum receiving funnel 70 by gravity for discharge.

[0040] It should be noted that the water filtering holes 21 of the filter screen 20 are formed by punching technology. By reasonably designing the mold, the water filtering holes 21 can be punched out while the part of the plate forming the water filtering holes 21 protrudes to one side of the plate to simultaneously obtain the C-shaped groove 22, which makes the processing more efficient and convenient, and the cost is lower.

[0041] In one embodiment, a movable observation hole 13 is provided on the top wall of the device housing 10, and the movable observation hole 13 is opposite to the cleaning nozzle 90a and the filter screen 20. During the operation of the automatic surface water slag removal device 100, the staff can observe the working conditions inside the device in real time through the movable observation hole 13, so as to intervene in time when an emergency occurs or the filtering treatment effect is not good.

[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
