Description

Technical Field

[0001] The utility model belongs to the field of return water filtering devices, and particularly relates to a return water filtering device with an automatic backwashing function. Background Art

[0002] All the stuffing box water of the slurry pumps in the production workshop of the concentrator uses clean water, and about 15,000 m³ of clean water is used per month. The long-term use of clean water not only causes waste of clean water, but also causes the water level of the tailings pond to rise continuously, and there are safety and environmental protection risks in the tailings pond. The stuffing box water of the slurry pumps was changed to return water for trial use, but there are many sundries in the return water, which frequently block the water channels of the slurry pumps. To clean the sundries in the water channels, the slurry pumps need to be disassembled, and after cleaning, they need to be reinstalled. Two mechanics spend four hours each time cleaning, and frequent cleaning brings a huge workload to the employees. At the same time, there are safety risks in frequently cleaning the slurry pumps. If the slurry pumps malfunction, it will inevitably affect production. To solve the problem of sundries in the return water, a return water filtering device is needed. The purpose of the return water filtering device is to remove impurities, particulate matters and sediments in the return water. In the prior art, when the device is in use, the filter screen is inconvenient to be backwashed and cleaned, resulting in a possible reduction in the working efficiency of the filter screen on the device. Therefore, the prior art needs to be improved. Summary of the Invention

[0003] The purpose of the utility model is to provide a return water filtering device with an automatic backwashing function, which solves the problem that when the device is in use, the filter screen is inconvenient to be backwashed and cleaned, resulting in a possible reduction in the working efficiency of the filter screen on the device.

[0004] To achieve the above object, the utility model provides a return water filtering device with an automatic backwashing function, which comprises a housing. An inlet is arranged inside the housing. An inlet pressure gauge is arranged outside the inlet. A first partition net is fixedly connected inside the inlet. An outlet is arranged inside the housing. An outlet pressure gauge is arranged outside the outlet. A second partition net is fixedly connected inside the outlet. A high molecular polyethylene pipe is arranged inside the outlet. A water pump is arranged inside the housing. A baffle is fixedly connected inside the housing. A filter net is fixedly connected to the baffle. The housing is fixedly connected to the filter net. A motor is fixedly installed at the upper end of the housing. The rotating shaft of the motor is rotatably connected to the housing. A lead screw is fixedly connected to the rotating shaft of the motor. The lead screw is rotatably connected inside the housing. A sliding block is threadedly connected to the outside of the lead screw. A high-pressure washer is fixedly installed on the sliding block. A connecting sleeve is fixedly sleeved inside the housing. A hose is arranged inside the connecting sleeve. A hose is arranged on the high-pressure washer. A connecting pipe is slidably connected inside the connecting sleeve. A limiting mechanism is arranged at the upper end of the connecting sleeve. A sewage outlet is arranged inside the housing. By starting the motor and the high-pressure washer, the motor drives the lead screw and the sliding block to perform a threaded movement. The movement of the sliding block drives the high-pressure washer to wash the filter net, so that the filter net is cleaned, preventing the working efficiency of the filter net on the device from decreasing.

[0005] The principle of the utility model is as follows: when the connecting pipe needs to be limited, insert the connecting pipe into the connecting sleeve from the connecting seat, and then rotate the handle. The rotation of the handle drives the screw to rotate. The rotation of the screw performs a threaded movement with the connecting seat, so that the screw generates a relative displacement. The rotation of the screw drives the second bearing and the annular sleeve to move. The movement of the annular sleeve drives the limiting block to move. The movement of the limiting block contacts the connecting pipe, so that the connecting pipe is limited, preventing the slippage between the connecting sleeve and the connecting pipe.

[0006] When the filter net on the device needs to be backwashed, start the motor and the high-pressure washer. The motor drives the lead screw to rotate. The rotation of the lead screw performs a threaded movement with the sliding block, so that the sliding block generates a relative displacement. The movement of the sliding block drives the high-pressure washer to move. The high-pressure washer washes the filter net while moving, so that the filter net is cleaned, preventing the working efficiency of the filter net on the device from decreasing.

[0007] The beneficial effects of the present utility model are as follows: By designing components such as a connecting seat, a screw rod, a handle, an annular sleeve, a second bearing, and a limiting block, the connecting pipe is inserted into a specified position within the connecting sleeve, and then the limiting block is moved. The limiting block moves into contact with the connecting pipe, thereby limiting the connecting pipe and preventing slippage between the connecting sleeve and the connecting pipe. By designing components such as a motor, a lead screw, a first bearing, a sliding block, a guide rod, and a high-pressure flusher, the motor and the high-pressure flusher are started. The motor drives the lead screw to perform a threaded movement with the sliding block, and the movement of the sliding block drives the high-pressure flusher to flush the filter screen, thereby cleaning the filter screen and preventing the working efficiency of the filter screen on the device from decreasing.

[0008] Further, one end of the water pump is provided with a water outlet, and the other end of the water pump is provided with a water suction pipe. By designing the water pump, the water in the housing can be pumped out.

[0009] Further, a first bearing is fixedly sleeved inside the housing, and a lead screw is fixedly sleeved inside the first bearing. By designing the first bearing, it can be used to support the rotation of the lead screw.

[0010] Further, a guide rod is fixedly connected inside the housing, and a sliding block is slidably connected to the outer side of the guide rod. By designing the guide rod, it can guide the sliding block.

[0011] Further, the limiting mechanism includes a connecting seat. The upper end of the connecting sleeve is fixedly connected with the connecting seat. A screw rod is threadedly connected inside the connecting seat. An annular sleeve is rotatably connected to the outer side of the screw rod. A limiting block is fixedly connected to the annular sleeve. The limiting block is slidably connected inside the connecting seat. The connecting pipe is in contact with the limiting block. By inserting the connecting pipe into a specified position within the connecting sleeve and then moving the limiting block, the limiting block moves into contact with the connecting pipe, thereby limiting the connecting pipe and preventing slippage between the connecting sleeve and the connecting pipe.

[0012] Further, a handle is fixedly connected to the screw rod. The handle is made of iron material. By designing the handle to be made of iron material, the handle is more durable.

[0013] Further, a second bearing is fixedly sleeved inside the annular sleeve, and a screw rod is fixedly sleeved inside the second bearing. By designing the second bearing, it can be used to support the rotation of the screw rod. BRIEF DESCRIPTION OF THE DRAWINGS

By designing the water pump 9, the water inside the housing 1 can be pumped out. Inside the housing 1, there is a baffle 11 fixedly connected. On the baffle 11, there is a filter net 12 fixedly connected. The filter net 12 is fixedly connected to the housing 1. At the upper end of the housing 1, there is a motor 13 fixedly installed. The rotating shaft of the motor 13 is rotationally connected to the housing 1. On the rotating shaft of the motor 13, there is a lead screw 14 fixedly connected. Inside the housing 1, the lead screw 14 is rotationally connected. Inside the housing 1, there is a first bearing 15 fixedly sleeved. Inside the first bearing 15, the lead screw 14 is fixedly sleeved. By designing the first bearing 15, it can be used to support the rotation of the lead screw 14. Outside the lead screw 14, there is a sliding block 16 threadedly connected. Inside the housing 1, there is a guide rod 17 fixedly connected. The sliding block 16 is slidably connected to the outside of the guide rod 17. By designing the guide rod 17, the sliding block 16 can be guided. On the sliding block 16, there is a high-pressure washer 18 fixedly installed. Inside the housing 1, there is a connecting sleeve 19 fixedly sleeved. Inside the connecting sleeve 19, there is a hose 20. The high-pressure washer 18 is provided with the hose 20. Inside the connecting sleeve 19, there is a connecting pipe 21 slidably connected. At the upper end of the connecting sleeve 19, there is a limiting mechanism 22. Inside the housing 1, there is a sewage outlet 23. By starting the motor 13 and the high-pressure washer 18, the motor 13 drives the lead screw 14 to perform a threaded movement with the sliding block 16. The movement of the sliding block 16 drives the high-pressure washer 18 to wash the filter net 12, thereby cleaning the filter net 12 and preventing the working efficiency of the filter net 12 on the device from decreasing.

[0024] As Figure 2 , Figure 6 , Figure 7 shown, the limiting mechanism 22 includes a connecting seat 221. The upper end of the connecting sleeve 19 is fixedly connected with the connecting seat 221. Inside the connecting seat 221, there is a screw rod 222 threadedly connected. On the screw rod 222, there is a handle 223 fixedly connected. The handle 223 is made of iron material.

[0025] AsFigure 6 , Figure 7 As shown in Figure 7 , a limiting block 226 is fixedly connected to the annular sleeve 224. The limiting block 226 is slidably connected to the inside of the connecting seat 221. A connecting pipe 21 is in contact with the limiting block 226. By inserting the connecting pipe 21 into a specified position inside the connecting sleeve 19 and then moving the limiting block 226, the limiting block 226 moves into contact with the connecting pipe 21, thereby limiting the connecting pipe 21 and preventing slippage between the connecting sleeve 19 and the connecting pipe 21.

[0026] The specific implementation process of the present utility model is as follows: When the connecting pipe 21 needs to be limited, insert the connecting pipe 21 from the connecting seat 221 into the connecting sleeve 19, and then rotate the handle 223. The rotation of the handle 223 drives the screw 222 to rotate. The rotation of the screw 222 makes a threaded movement with the connecting seat 221, thereby causing the screw 222 to generate a relative displacement. The rotation of the screw 222 drives the second bearing 225 and the annular sleeve 224 to move. The movement of the annular sleeve 224 drives the limiting block 226 to move. The limiting block 226 moves into contact with the connecting pipe 21, thereby limiting the connecting pipe 21 and preventing slippage between the connecting sleeve 19 and the connecting pipe 21;

[0027] When the filter screen 12 on the device needs to be backwashed, start the motor 13 and the high-pressure washer 18. The motor 13 drives the lead screw 14 to rotate. The rotation of the lead screw 14 makes a threaded movement with the sliding block 16, thereby causing the sliding block 16 to generate a relative displacement. The movement of the sliding block 16 drives the high-pressure washer 18 to move. The high-pressure washer 18 flushes the filter screen 12 while moving, thereby cleaning the filter screen 12 and preventing the working efficiency of the filter screen 12 on the device from decreasing.

[0028] In this solution, by designing components such as the connecting seat 221, screw 222, handle 223, annular sleeve 224, second bearing 225, and limiting block 226, insert the connecting pipe 21 into a specified position inside the connecting sleeve 19, and then move the limiting block 226. The limiting block 226 moves into contact with the connecting pipe 21, thereby limiting the connecting pipe 21 and preventing slippage between the connecting sleeve 19 and the connecting pipe 21. By designing components such as the motor 13, lead screw 14, first bearing 15, sliding block 16, guide rod 17, and high-pressure washer 18, start the motor 13 and the high-pressure washer 18. The motor 13 drives the lead screw 14 to make a threaded movement with the sliding block 16. The movement of the sliding block 16 drives the high-pressure washer 18 to flush the filter screen 12, thereby cleaning the filter screen 12 and preventing the working efficiency of the filter screen 12 on the device from decreasing.
