Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a water inlet rotary filtering device. Background Art

[0002] With the full development of my country's modernization drive, the shortage of water resources has become an important issue restricting my country's economic development. In order to solve the problem of urban water use, channels are usually dug to divert water. The channels are open channels, and garbage such as leaves and plastic bags will float into the channels. Moreover, with climate change and the increase in water delivery time, algae will grow in the water bodies in the channels. The water plants in the cities along the line take water from the water inlet on the slope of the channel through culverts. Algae, plastic bags, leaves and other debris in the water will enter the water plant from the water inlet and block the water treatment equipment. What's more, they will be deposited in the culvert to form a blockage, affecting the water use of the cities along the line. Therefore, a rotary filter device for the water inlet is specially designed. Summary of the invention

[0003] The purpose of the present invention is to provide a water inlet rotary filtering device, which can filter the water entering the water inlet, greatly reducing the situation where debris enters the water inlet and blocks the water plant equipment, and reduces the possibility of culvert clogging. The device is simple to operate, easy to clean, safe and reliable.

[0004] To achieve the above object, the present invention adopts the following technical solution:

[0005] The rotary filter device of the water inlet comprises a rotary filter frame, a filter cover, a fixed axis, a cleaning platform and a rotary drive mechanism. With the water flow direction in the water inlet as the forward direction and the length direction of the channel as the left-right direction, the rotary filter frame is laid on the channel slope along the slope of the channel with the front higher and the back lower. The rotary filter frame corresponds to the front and back of the water inlet and covers the water inlet. The filter cover is installed on the rear side of the rotary filter frame and covers the upper part of the water inlet. The fixed axis is vertically fixed on the upper side of the channel slope and is located on the upper front side of the water inlet. The front end of the rotary filter frame is rotatably installed on the fixed axis. The cleaning platform is horizontally installed on the bank of the channel slope along the left-right direction through a truss and is located on the upper right side of the fixed axis. The rotary drive mechanism is installed on the left side of the truss and connected to the front side of the rotary filter frame. The rotary drive mechanism drives the rotary filter frame to rotate.

[0006] The rotary filter frame is made of welded steel. The outer frame of the rotary filter frame is an isosceles trapezoidal frame on the front side and a rectangular frame on the rear side. The front side of the isosceles trapezoid is the upper base, and the lower side of the isosceles trapezoid is the lower base. Several pairs of universal wheels rollingly supported on the channel slope are installed at the bottom of the rotary filter frame. Each pair of universal wheels consists of two universal wheels spaced left and right. A rotating sleeve is welded to the middle of the front side beam of the rotary filter frame. The center line of the rotating sleeve is perpendicular to the rotary filter frame. A spherical roller bearing sleeved on the fixed shaft is installed inside the rotating sleeve. The rotating sleeve is rotatably installed on the fixed shaft through the spherical roller bearing.

[0007] The filter cover includes a first filter hole plate, which is arranged along the front-to-back direction and has an arched structure. The open side of the first filter hole plate faces downward, the left side of the first filter hole plate is fixedly connected to the rear side of the left beam of the rotary filter frame, the right side of the first filter hole plate is fixedly connected to the rear side of the right beam of the rotary filter frame, the rear side of the first filter hole plate corresponds to the rear side beam of the rotary filter frame up and down, the front side of the first filter hole plate is located at the front upper side of the front side of the water inlet, the front side port and the rear side port of the first filter hole plate are fixedly connected to the second filter hole plate, the second filter hole plate has an arched structure, the lower side of the front second filter hole plate is fixedly connected to a steel section arranged along the left-right direction in the middle of the rotary filter frame, and the lower side of the rear second filter hole plate is fixedly connected to the rear side beam of the rotary filter frame.

[0008] The rotary drive mechanism includes a hydraulic cylinder and a hydraulic pump station. A swing arm is welded on the right front side of the upper side of the outer circumference of the rotating sleeve. The swing arm is made of thick steel plate. The swing arm is higher in front and lower in the back, tilted to the right front and left rear and parallel to the channel slope. The angle between the swing arm and the rotary filter frame is 135°. The hydraulic cylinder is horizontally arranged at the rear side of the left side of the truss in the left and right directions. The front side surface of the left end of the outer circumference of the hydraulic cylinder is hinged to the rear side of the left end of the truss and its hinge axis is parallel to the fixed axis. The piston rod of the hydraulic cylinder extends to the left, and the left end of the piston rod of the hydraulic cylinder is hinged to the front end of the swing arm and its hinge axis is parallel to the fixed axis. The hydraulic pump station is arranged on the left side of the cleaning platform, and the hydraulic pump station is connected to the hydraulic cylinder through a hydraulic pipeline.

[0009] The water inlet rotary filtering device also includes a step ladder, which is laid downward along the channel slope at the left end of the cleaning platform and corresponds to the front and back of the water inlet. The step ladder is welded to the left end of the truss. The step ladder is made of welded steel sections, and a fixed axis is welded to the rear end of the step ladder.

[0010] Compared with the prior art, the present invention has outstanding substantial features and significant progress. Specifically, the operating principle of the present invention is as follows: when the water inlet rotary filter device is in working state, the rotary filter frame is laid on the channel slope along the slope of the channel with the front higher and the back lower. The rotary filter frame corresponds to the front and back of the water inlet and covers the water inlet. The filter cover covers the upper part of the water inlet. Then the first filter hole plate just covers the water inlet. The first filter hole plate and the second filter hole plate filter the water entering the water inlet, and intercept floating objects such as clumped algae, plastic bags, leaves, etc. outside the water inlet, which greatly reduces the situation where debris enters the water inlet and blocks the water plant equipment, and reduces the possibility of clogging of the culvert. Among them, the first filter hole plate has an arched structure, which can increase the water flow area and avoid the loss of water intake flow at the water inlet. At the same time, the arched surface has a certain diversion capacity for the water flow, which reduces the water blocking capacity of the overall equipment, and the debris in the water body is not easy to adhere to the surface of the first filter hole plate, which ensures that the first filter hole plate can operate for a long time. When the water inlet is rotary, the water inlet is not easy to adhere to the surface of the first filter hole plate, which ensures that the first filter hole plate can operate for a long time. After the filtering device has been running for a long time, it is inevitable that debris is attached to the surface of the first filter plate and the second filter plate, which affects the water flow capacity and causes the water intake flow rate of the water intake to decrease. Then the staff starts the hydraulic pump station and controls the piston rod of the hydraulic cylinder to extend to the left. The piston rod of the hydraulic cylinder pushes the swing arm to rotate the rotating sleeve 90° counterclockwise, thereby making the rotary filter frame rotate 90° counterclockwise around the fixed axis on the channel slope through the universal wheels at the bottom. The rotary filter frame drives the filter cover to rotate out of the water surface to the rear lower side of the cleaning platform and parallel to the cleaning platform. Then, the worker goes down to the cleaning platform through the step ladder to clean the debris on the surface of the first filter plate and the second filter plate. After the cleaning is completed, the piston rod of the hydraulic cylinder is controlled to retract to the right to the initial state, thereby rotating the rotary filter frame 90° clockwise to the working position, so that the filter cover covers the upper part of the water intake again, and the first filter plate just covers the water intake. The first filter plate and the second filter plate continue to filter the water entering the water intake. The operation is simple, the cleaning is convenient, and it is safe and reliable.

[0011] A spherical roller bearing sleeved on a fixed shaft is installed inside the rotating sleeve. The spherical roller bearing can adapt to the slightly uneven condition of the channel slope during the rotation of the rotary filter frame, ensuring the smooth rotation of the rotary filter frame.

[0012] The rotary drive mechanism of the present invention may also adopt other driving modes, such as using an electric push rod or a lead screw nut mechanism to drive the swing arm to rotate, or using an electric motor to directly drive the rotating sleeve to rotate.

[0013] The present invention can also be used on the vertical wall of an artificial main channel or the side slope of a natural river channel, that is, the rotary filter frame is rotatably installed on the vertical wall of an artificial main channel or the side slope of a natural river channel.

[0014] In summary, the present invention can filter the water entering the water inlet, greatly reducing the situation where debris enters the water inlet and blocks the water plant equipment, and reduces the possibility of culvert clogging. It is simple to operate, easy to clean, safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The embodiments of the present invention are further described below with reference to the accompanying drawings.

[0022] like Figure 1-6 As shown, the water inlet rotary filter device comprises a rotary filter frame 1, a filter cover, a fixed axis 2, a cleaning platform 3 and a rotary drive mechanism. With the water flow direction in the water inlet 4 as the forward direction and the length direction of the channel as the left-right direction, the rotary filter frame 1 is laid on the channel slope 5 along the slope of the channel with a high front and a low back. The rotary filter frame 1 corresponds to the water inlet 4 front and back and covers the water inlet 4. The filter cover is installed on the rear side of the rotary filter frame 1 and covers the upper part of the water inlet 4. The fixed axis 2 is vertically fixedly arranged on the upper side of the channel slope 5 and is located on the upper front side of the water inlet 4.

The rotary drive mechanism drives the rotary filter frame 1 to rotate.

[0023] The rotary filter frame 1 is made of welded steel. The outer frame of the rotary filter frame 1 is an isosceles trapezoidal frame on the front side and a rectangular frame on the rear side. The front side of the isosceles trapezoid is the upper base, and the lower side of the isosceles trapezoid is the lower base. A plurality of pairs of universal wheels 7 rollingly supported on the channel slope 5 are installed at the bottom of the rotary filter frame 1. Each pair of universal wheels 7 is two universal wheels 7 spaced apart from each other. A rotating sleeve 8 is welded to the middle of the front side beam of the rotary filter frame 1.

The rotating sleeve 8 is rotatably installed on the fixed shaft 2 through the spherical roller bearing.

[0024] The filter cover includes a first filter hole plate 9, which is arranged along the front-to-back direction and has an arched structure. The open side of the first filter hole plate 9 faces downward, the left side of the first filter hole plate 9 is fixedly connected to the rear side of the left beam of the rotary filter frame 1, and the right side of the first filter hole plate 9 is fixedly connected to the rear side of the right beam of the rotary filter frame 1. The rear side of the first filter hole plate 9 corresponds to the rear side beam of the rotary filter frame 1 up and down, and the front side of the first filter hole plate 9 is located at the front upper side of the front side of the water inlet 4. The front side port and the rear side port of the first filter hole plate 9 are fixedly connected with the second filter hole plate 10, and the second filter hole plate 10 has an arched structure. The lower side of the front second filter hole plate 10 is fixedly connected to a steel section arranged along the left-right direction in the middle of the rotary filter frame 1, and the lower side of the rear second filter hole plate 10 is fixedly connected to the rear side beam of the rotary filter frame 1.

[0025] The rotary drive mechanism includes a hydraulic cylinder 11 and a hydraulic pump station 12. A swing arm 13 is welded to the right front side of the upper side of the outer circumference of the rotating sleeve 8. The swing arm 13 is made of thick steel plate. The swing arm 13 is high in front and low in back, tilted in the right front and left rear and parallel to the channel slope 5. The angle between the swing arm 13 and the rotary filter frame 1 is 135°. The hydraulic cylinder 11 is horizontally arranged at the rear side of the left side of the truss 6 in the left and right directions. The front side surface of the left end of the outer circumference of the hydraulic cylinder 11 is hinged to the rear side of the left end of the truss 6 and its hinge axis is parallel to the fixed axis 2. The piston rod of the hydraulic cylinder 11 extends to the left, and the left end of the piston rod of the hydraulic cylinder 11 is hinged to the front end of the swing arm 13 and its hinge axis is parallel to the fixed axis 2. The hydraulic pump station 12 is arranged on the left side of the cleaning platform 3, and the hydraulic pump station 12 is connected to the hydraulic cylinder 11 through a hydraulic pipeline (not shown).

[0026] The water inlet rotary filtering device also includes a step ladder 14, which is laid downward along the channel slope 5 at the left end of the cleaning platform 3 and corresponds to the front and back of the water inlet 4. The step ladder 14 is welded to the left end of the truss 6. The step ladder 14 is made of welded steel sections, and the fixed axis 2 is welded to the rear end of the step ladder 14.

[0027] The spherical roller bearing, hydraulic cylinder 11, hydraulic pump station 12 and step ladder 14 are all conventional technologies, and the specific structure and working principle are not repeated here. The hydraulic control technology of the present invention is conventional technology.

[0028] The operating principle of the present invention is as follows: when the water inlet rotary filter device is in working state, the rotary filter frame 1 is laid on the channel slope 5 along the slope of the channel side slope 5 with the slope being high in front and low in the back, the rotary filter frame 1 corresponds to the water inlet 4 front and back and covers the water inlet 4, the filter cover covers the upper part of the water inlet 4, and the first filter hole plate 9 just covers the water inlet 4, the first filter hole plate 9 and the second filter hole plate 10 filter the water entering the water inlet 4, and intercept floating objects such as clumping algae, plastic bags, leaves, etc. outside the water inlet 4, which greatly reduces the water pollution. The situation where debris enters the water inlet 4 and blocks the water plant equipment is reduced, and the possibility of clogging of the culvert is reduced. Among them, the first filter hole plate 9 is an arched structure, which can increase the water flow area and avoid the loss of water flow from the water inlet 4. At the same time, the arched surface has a certain flow diversion ability for the water flow, which reduces the water resistance of the overall equipment. In addition, debris in the water body is not easy to adhere to the surface of the first filter hole plate 9, ensuring that the first filter hole plate 9 can operate for a long time. When the water inlet rotary filter device has been running for a long time, the first filter hole plate 9 and the surface of the second filter plate 10 are inevitably attached with debris, which affects the water flow capacity and causes the water intake flow rate of the water inlet 4 to decrease. The staff starts the hydraulic pump station 12 to control the piston rod of the hydraulic cylinder 11 to extend to the left. The piston rod of the hydraulic cylinder 11 pushes the swing arm 13 to make the rotating sleeve 8 rotate 90° counterclockwise, thereby making the rotary filter frame 1 rotate 90° counterclockwise around the fixed axis 2 on the channel slope 5 through the universal wheels 7 at the bottom. The rotary filter frame 1 drives the filter cover to rotate out of the water to the rear lower side of the cleaning platform 3 and with the filter cover 1. The workers go down to the cleaning platform 3 through the step ladder 14 to clean the debris on the surface of the first filter hole plate 9 and the second filter hole plate 10. After the cleaning is completed, the piston rod of the hydraulic cylinder 11 is controlled to retract to the right to return to the initial state, thereby rotating the rotary filter frame 1 90° clockwise to the working position, so that the filter cover covers the upper part of the water inlet 4 again, and the first filter hole plate 9 just covers the water inlet 4. The first filter hole plate 9 and the second filter hole plate 10 continue to filter the water entering the water inlet 4.

[0029] A spherical roller bearing sleeved on the fixed shaft 2 is installed inside the rotating sleeve 8. The spherical roller bearing can adapt to the slightly uneven condition of the channel slope 5 during the rotation of the rotary filter frame 1, thereby ensuring the smooth rotation of the rotary filter frame 1.

[0030] The rotary drive mechanism of the present invention may also adopt other driving modes, such as using an electric push rod or a screw nut mechanism to drive the swing arm 13 to rotate, or using an electric motor to directly drive the rotating sleeve 8 to rotate.

[0031] The present invention can also be used on the vertical wall of an artificial main canal or the slope of a natural river channel, that is, the rotary filter frame 1 is rotatably installed on the vertical wall of an artificial main canal or the slope of a natural river channel.
