Description

Technical Field

[0001] This utility model relates to the field of cylindrical screen technology, and in particular to a screen washing device for a cylindrical screen. Background Technology

[0002] Cylindrical screens can be widely used for screening dry powdery or granular materials in industries such as metallurgy, building materials, chemicals, grain, medicine, abrasives and fertilizers. They are particularly suitable for dry production of manufactured sand and can also be used for screening granular wet materials.

[0003] Cylindrical screens are used in gravity separation plants for washing and desliming ore, or for classifying medium and fine-grained materials, yielding two or more products. Currently, manufacturers using cylindrical screens generally solve the problem of screen clogging by washing the screen mesh; however, the water source is usually treated wastewater from the production process, which contains a significant amount of impurities.

[0004] For spray nozzle flushing devices with a multi-porous surface, the nozzles are prone to clogging after long-term use, requiring frequent replacement and cleaning. This consumes a lot of manpower and resources, while also making it difficult to improve the production capacity of the cylindrical screen. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a screen washing device for a cylindrical screen.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A screen washing device for a cylindrical screen includes a spray bracket clamped on a cylindrical screen mounting frame. A cylindrical screen is rotatably mounted on the inner walls of both ends of the cylindrical screen mounting frame, and a drive shaft is rotatably connected to both ends of the inner wall of the cylindrical screen through a triangular bracket. One end of the drive shaft is connected to a drive motor. A water storage tank is provided on one side of the spray bracket, and a filter assembly is provided in the water storage tank.

[0008] The spray support includes two clamping components, and the two clamping components are fixedly connected to each other by two fixing rods;

[0009] In the above solution, the clamping components can be quickly disassembled, making it easy to replace the high-pressure nozzles or clean the spray pipes; the filter media can be flexibly replaced, such as activated carbon to remove odors and sponge to intercept particles, reducing maintenance costs.

[0010] The clamping assembly includes an arched frame, and both ends of the arched frame are provided with connecting rods, and the ends of the connecting rods are fixed with clamping blocks, which are engaged with the inner wall of the cylindrical screen mounting frame.

[0011] A spray pipe is fixed to the outer wall of the two arched frames on opposite sides of the middle section, and high-pressure nozzles are installed at equal intervals at the bottom of the spray pipe.

[0012] The filter assembly includes a first partition, a second partition, a third partition, and a fixing plate, wherein the heights of the first partition, the second partition, and the third partition decrease sequentially.

[0013] The space between the third partition and the fixed plate is filled with filter medium. A high-pressure water pump is installed on the side of the fixed plate away from the third partition.

[0015] Preferably, the high-pressure nozzle is a duckbill nozzle, and the outlet of the high-pressure nozzle is an integral open structure.

[0016] In the above scheme, the high-pressure nozzle adopts a duckbill design with an integral open structure at the outlet, which can greatly reduce the probability of the outlet being blocked and form a fan-shaped water curtain covering the screen surface; the filter component uses a three-stage baffle for graded sedimentation and filter media to adsorb impurities, effectively preventing nozzle blockage, extending equipment life, realizing the recycling of greywater, and reducing water waste.

[0018] Preferably, the water storage tank has an inlet at the end away from the high-pressure water pump, and the inner wall of the inlet is connected to a greywater inlet pipe.

[0019] Preferably, the arched frame is a semi-circular structure, and the arched frame is coaxially arranged with the cylindrical screen.

[0020] In the above scheme, the rinsing device has a stable structure and precise positioning. The arched frame and the cylindrical screen are designed to be coaxial. Combined with the locking structure of the clamping block and the fastening knob, it ensures that the distance between the spray pipe and the screen is constant and avoids blind spots in rinsing.

[0021] The beneficial effects of this utility model are as follows:

[0022] The clamping components can be quickly disassembled, making it easy to replace the high-pressure nozzles or clean the spray pipes; the filter media can be flexibly replaced, such as activated carbon to remove odors and sponge to intercept particles, reducing maintenance costs;

The filter component uses a three-stage diaphragm for graded sedimentation and filter media to adsorb impurities, effectively preventing nozzle clogging, extending equipment life, realizing the recycling of greywater, and reducing water waste.

[0024] The rinsing device has a stable structure and precise positioning. The arched frame and the cylindrical screen are coaxially designed, and the locking structure of the clamping block and the fastening knob ensures that the distance between the spray pipe and the screen is constant, avoiding blind spots in rinsing.

[0033] The clamping assembly can be quickly disassembled for easy replacement of high-pressure nozzles or cleaning of spray pipes; the filter medium 15 can be flexibly replaced, such as activated carbon to remove odors or sponge to intercept particles, reducing maintenance costs.

[0034] The clamping assembly includes an arched frame 3, and both ends of the arched frame 3 are provided with connecting rods 4, and the ends of the connecting rods 4 are fixed with clamping blocks 5, and the clamping blocks 5 are clamped on the inner wall of the cylindrical screen mounting frame 1.

[0035] A spray pipe 8 is fixed to the outer wall of the two arched frames 3 on opposite sides in the middle, and high-pressure nozzles 9 are installed at equal intervals at the bottom of the spray pipe 8.

[0036] The filter assembly includes a first partition 11, a second partition 12, a third partition 13, and a fixed plate 14, with the heights of the first partition 11, the second partition 12, and the third partition 13 decreasing sequentially.

[0037] The space between the third partition 13 and the fixed plate 14 is filled with filter medium 15. A high-pressure water pump 16 is provided on the side of the fixed plate 14 away from the third partition 13. The outlet of the high-pressure water pump 16 is connected to a water supply pipe 17, which is connected to the spray pipe 8.

[0038] The top of the clamping block 5 has a bolt hole, and the bolt hole is threaded with a fastening knob 6. The cylindrical screen mounting bracket 1 has a bolt fixing hole that matches the fastening knob 6.

[0039] The high-pressure nozzle 9 is a duckbill nozzle, and the outlet of the high-pressure nozzle 9 is an integral open structure.

[0040] The high-pressure nozzle 9 adopts a duckbill design with an integral open structure at the outlet, which greatly reduces the likelihood of the outlet being blocked and forms a fan-shaped water curtain covering the screen surface. The filter component uses a three-stage diaphragm for graded sedimentation and filter media 15 to adsorb impurities, effectively preventing nozzle clogging, extending equipment life, realizing the recycling of greywater, and reducing water waste.

[0041] The filter medium 15 is a sponge, porous filter stone, or activated carbon.

[0042] The water storage tank 10 has an inlet at the end away from the high-pressure water pump 16, and the inner wall of the inlet is connected to a greywater inlet pipe 18.

[0043] The arched frame 3 is a semi-circular structure, and the arched frame 3 is coaxially arranged with the cylindrical screen 2.

[0044] The rinsing device has a stable structure and precise positioning. The arched frame 3 and the cylindrical screen 2 are designed to be coaxial. Combined with the locking structure of the clamping block 5 and the fastening knob 6, it ensures that the distance between the spray pipe 8 and the screen is constant and avoids blind spots in rinsing.

[0045] The specific installation and usage steps are as follows:

[0046] Step 1: Install the sprinkler bracket

[0047] Place the two arched frames (3) on both sides of the cylindrical screen mounting frame (1), insert them into the inner wall of the mounting frame through the clamping blocks (5), and tighten the fastening knob (6) to fix them.

[0048] Connect the two arched frames (3) with two fixed rods (7) to ensure that the spray pipe (8) is located directly above the cylindrical screen (2) and is coaxial and parallel. The semi-circular structure of the arched frame (3) avoids the drive shaft to prevent interference with operation.

[0049] Step 2: Configure the filtration system

[0050] The first baffle (11) (200mm high), the second baffle (12) (150mm high), and the third baffle (13) (100mm high) are installed in sequence in the water storage tank (10) to form a stepped overflow channel.

[0051] Activated carbon (filter medium 15) is filled between the third partition (13) and the fixed plate (14), and a high-pressure water pump (16) is installed on the outside of the fixed plate (14).

[0052] Step 3: Connect the waterway

[0053] The greywater inlet pipe (18) is connected to the head end of the water storage tank (10); the outlet of the high-pressure water pump (16) is connected to the spray pipe (8) through the water supply pipe (17).

[0054] Duckbill-type high-pressure nozzles (9) are installed at 150mm intervals at the bottom of the spray pipe (8), with the nozzles facing the screen. The fan-shaped water curtain of the duckbill nozzles (9) covers the full width of the screen and is adapted to the curvature of the cylindrical screen.

[0055] Step 4: Operation and Maintenance

[0056] Start the drive motor to rotate the cylindrical screen (2) (5-10 r / min), and turn on the high-pressure water pump (16) to form a 20-30 bar flushing water pressure.

[0057] Check the filter media (15) monthly and replace it when the activated carbon is saturated; regularly disassemble the clamping components to clean the scale buildup on the spray pipes.

[0058] Working principle:

[0059] The greywater enters the storage tank 10 from the greywater inlet pipe 18, flows through the first baffle 11 to settle large particles of impurities, overflows to the second baffle 12 for secondary sedimentation, and overflows to the third baffle 13 for deep purification through the filter medium 15.

[0060] High-pressure water pump 16 draws purified water and delivers it to spray pipe 8 through water supply pipe 17, and sprays it onto the inner wall of rotating cylindrical screen 2 by high-pressure nozzle 9.

[0061] The cylindrical screen 2 rotates under the drive of the motor, and the fan-shaped water curtain of the high-pressure nozzle 9 continuously washes the screen mesh and removes the blockages;

[0062] The filter media 15 traps fine impurities, and its filtration performance can be restored after regular replacement or cleaning; the three-stage baffle design delays media saturation and improves filtration efficiency.

[0063] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
