Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a device for cleaning a lime slurry conveying system. Background Technology

[0002] The current lime slurry used in the wastewater treatment system is transported to the wastewater equalization tank via two pneumatic pumps (one in use and one on standby). The pipes are DN15 plastic pipes and are used for 8 hours a day. Because it is not used continuously and the pipes are relatively narrow, and the lime slurry is alkaline, lime from the lime slurry in the system will settle in the pipes after each day's use. Over time, the lime will harden and clog the pipes and pumps, making it unusable. The pipes and pumps must be dismantled and cleaned every month before it can be used again, which consumes a lot of manpower and resources and also affects normal production. Utility Model Content

[0003] The technical problem to be solved by this utility model is that when lime slurry is transported to the wastewater regulating tank through pipelines, some lime slurry is prone to deposit in the pipelines, causing blockage.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a device for cleaning a lime slurry conveying system, including a lime slurry tank and a wastewater regulating tank connected by a liquid delivery pipe, a water tank connected to the connection end of the liquid delivery pipe and the lime slurry tank, the connection end of the liquid delivery pipe and the wastewater regulating tank connected to the lime slurry tank through a flushing pipe, a filter box connected to the flushing pipe, and a pneumatic pump installed on the liquid delivery pipe.

[0005] Preferably, the liquid delivery pipeline includes a first liquid delivery pipeline and a second liquid delivery pipeline. A second valve and a fourth valve are installed on the first liquid delivery pipeline, and a third valve and a fifth valve are installed on the second liquid delivery pipeline. The flushing pipeline includes a first liquid return pipeline and a second liquid return pipeline. A seventh valve and an eighth valve are respectively installed on the first liquid return pipeline and the second liquid return pipeline. The second valve and the third valve are respectively installed at the input ends of the first liquid delivery pipeline and the second liquid delivery pipeline. The fourth valve and the seventh valve are respectively installed on two parallel branches at the output end of the first liquid delivery pipeline. The fifth valve and the eighth valve are respectively installed on two parallel branches at the output end of the second liquid delivery pipeline.

[0006] Preferably, a first valve and a sixth valve are installed on the output ends of the lime slurry tank and the water tank, respectively.

[0007] Preferably, the filter box includes a box body, an inlet pipe and a return pipe respectively connected to the top and bottom of the side wall of the box body, and a filter plate arranged inside the box body. The filter plate is located between the inlet pipe and the return pipe. The inlet pipe is connected to the flushing pipe, the return pipe is connected to the lime slurry tank, and a flushing pipe is arranged on the side wall of the box body. The flushing pipe is arranged parallel to the filter plate.

[0008] Preferably, the filter plate is arranged at an angle, the flushing pipe is located at the top of the filter plate, and the flushing pipe is arranged towards the bottom of the filter plate.

[0009] Preferably, a slag pipe is vertically fixed inside the box, with the top end of the slag pipe located on one side of the bottom end of the filter plate.

[0010] Preferably, the filter plate is fixedly arranged in parallel with the filter plate, and the filter plates are equidistant along the width direction of the filter plate, and the flushing pipe is arranged between two adjacent filter plates.

[0011] Preferably, a manhole is provided on the top of the enclosure.

[0012] This invention provides a device for cleaning a lime slurry conveying system, which has the following beneficial effects.

[0013] 1. After using the lime slurry conveying pipeline, the conveying pipeline is flushed through the water tank and flushing pipeline. This perfectly solves the problem of residual lime slurry in the system (pipeline, pneumatic pump) hardening and clogging the pipeline and equipment due to the intermittent use of the lime slurry conveying system, which prevents normal use and avoids the problem of having to dismantle the pipeline for cleaning every month.

[0014] 2. After flushing the lime slurry in the pipeline, it is separated through a filter box, and the lime slurry produced from flushing the pipeline is recycled back to the lime slurry tank, realizing the reuse of wastewater. Attached Figure Description

[0020] likeFigures 1-3 As shown, this utility model provides a device for cleaning a lime slurry conveying system, including a lime slurry tank 1 and a wastewater regulating tank 2 connected by a liquid delivery pipe. The connection end of the liquid delivery pipe to the lime slurry tank 1 is also connected to a water tank 3. The connection end of the liquid delivery pipe to the wastewater regulating tank 2 is connected to the lime slurry tank 1 through a flushing pipe. A filter box 6 is connected to the flushing pipe. A pneumatic pump is installed on the liquid delivery pipe.

[0021] Lime slurry is supplied through lime slurry tank 1 and transported through a delivery pipeline to wastewater equalization tank 2 by a pneumatic pump. After the lime slurry is delivered, the valves at the output end of lime slurry tank 1 and the inlet end of wastewater equalization tank 2 are closed, and the valve of water tank 3 is opened. Clean water is supplied through water tank 3 to flush the delivery pipeline. The liquid mixed with lime slurry obtained from the flushing is transported to filter box 6 through the flushing pipeline. After large particles are precipitated and filtered by filter box 6, the low-concentration lime slurry is transported back to lime slurry tank 1 for reuse.

[0022] like Figure 1 As shown. The liquid delivery pipeline includes a first liquid delivery pipeline and a second liquid delivery pipeline. A second valve 8 and a fourth valve 10 are installed on the first liquid delivery pipeline, and a third valve 9 and a fifth valve 11 are installed on the second liquid delivery pipeline. The flushing pipeline includes a first liquid return pipeline and a second liquid return pipeline. A seventh valve 13 and an eighth valve 14 are installed on the first liquid return pipeline and the second liquid return pipeline, respectively. The second valve 8 and the third valve 9 are respectively installed at the input ends of the first liquid delivery pipeline and the second liquid delivery pipeline. The fourth valve 10 and the seventh valve 13 are respectively installed on two parallel branches at the output end of the first liquid delivery pipeline. The fifth valve 11 and the eighth valve 14 are respectively installed on two parallel branches at the output end of the second liquid delivery pipeline.

[0023] When the lime slurry system is in operation, valves 7, 8, 9, 10, and 11 are opened sequentially to transport the lime slurry in the lime slurry tank 1 to the wastewater regulating tank 2 via pneumatic pumps 4 and 5. After the lime slurry system is in use, valves 7, 10, and 11 are closed sequentially, and valves 12, 13, and 14 are opened. Pneumatic pumps 4 and 5 are started to deliver tap water to the first and second delivery pipes to clean the delivery pipes and pneumatic pumps, so that the residual lime slurry inside is washed back into the filter box 6. After being filtered by the filter box 6, the lime slurry is delivered to the lime slurry tank 1. Pneumatic pumps 4 and 5 are turned off after five minutes, and valves 12, 13, and 14 are closed at the same time, thus ending the cleaning process.

[0024] like Figure 1As shown, this is to control the output of liquid in lime slurry tank 1 and water tank 3. A first valve 7 and a sixth valve 12 are respectively installed on the output ends of the lime slurry tank 1 and water tank 3.

[0025] like Figure 2 and Figure 3 As shown. The filter box 6 includes a box body 61, an inlet pipe 62 and a return pipe 63 respectively connected to the top and bottom of the side wall of the box body 61, and a filter plate 65 arranged inside the box body 61. The filter plate 65 is located between the inlet pipe 62 and the return pipe 63. The inlet pipe 62 is connected to the flushing pipe, and the return pipe 63 is connected to the lime slurry tank 1. A flushing pipe 67 is arranged on the side wall of the box body 61, and the flushing pipe 67 is arranged parallel to the filter plate 65. After the cleaning process is completed, it is necessary to clean the particles remaining on the filter plate 65 by flushing the filter plate 65 through the flushing pipe 67 to prevent the filter plate 65 from being blocked by particles.

[0026] like Figure 2 As shown. The filter plate 65 is arranged at an angle, and the flushing pipe 67 is located at the top of the filter plate 65, facing the bottom of the filter plate 65. The angled arrangement of the filter plate 65 allows the flushing pipe 67 to smoothly flush the particles on the filter plate 65 to the bottom of the filter plate 65, ensuring the unobstructed flow of the filter plate 65 mesh.

[0027] like Figure 2 and Figure 3 As shown. A slag pipe 64 is vertically fixed inside the housing 61, with the top end of the slag pipe 64 located on one side of the bottom end of the filter plate 65. Particles flushed down by the water pipe 67 can directly enter the slag pipe 64, facilitating the cleaning of particles inside the housing 61.

[0028] like Figure 2 and Figure 3 As shown, to ensure the strength of the filter plate 65, ribs 66 are fixedly arranged parallel to each other on the filter plate 65. The ribs 66 are equidistantly arranged along the width direction of the filter plate 65, and the flushing pipes 67 are arranged between two adjacent ribs 66. The ribs 66 are equidistantly arranged, with their bottoms connected to the top surface of the filter plate 65, and their two ends connected to the inner side wall of the housing 61 and the outer side wall of the slag pipe 64, respectively, providing stable support for the filter plate 65. Moreover, the flushing pipes 67 are arranged in the gaps formed between adjacent ribs 66 to specifically flush the filter plate 65.

[0029] like Figure 2 Figure 3 As shown. A manhole 68 is provided on the top of the housing 61. Workers can observe the interior of the housing 61 through the manhole 68 and turn on the corresponding flushing pipe 67 to rinse the top of the filter plate 65.
