Description

Technical Field

[0001] This utility model belongs to the field of mechanical production equipment technology, specifically relating to a line pump integrated process energy consumption reduction system. Background Technology

[0002] In the paper industry, linear pump systems are crucial for production efficiency and cost control. With increasing demands for refined management within the industry, the integration and optimization of linear pump systems has become a key area for technological improvement. Currently, in linear pump systems, the flushing tank water supply pump and the underwire white water pump operate simultaneously. While this mode allows white water to enter the flushing tank and pulping white water trays separately, ensuring production continuity, long-term operation has significant drawbacks, impacting equipment efficiency and increasing overall costs. Firstly, power utilization is low. Simultaneous operation of both pumps requires continuous power consumption, but the flushing tank water supply and white water treatment demands are not always high. Often, a single pump operates at low load or only needs standby, while both pumps operate at full / high power, resulting in energy waste and contradicting energy conservation and emission reduction principles. Secondly, the simultaneous operation of both pumps is unreasonable, reducing the actual utilization rate of the equipment. Long-term, unnecessary simultaneous operation prevents the equipment from operating at its optimal condition, shortening its lifespan and increasing maintenance frequency and costs. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a line pump integrated process energy-saving system.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A line pump integrated process energy-saving system includes an under-net white water tank. A flushing tank water supply pump and an under-net white water pump are connected in parallel on one side of the under-net white water tank. The flushing tank water supply pump is connected to the flushing tank via a flushing tank pipeline. The under-net white water pump is connected to the pulping white water multi-pan via a white water pipeline. A parallel pipeline is provided between the flushing tank pipeline and the white water pipeline to connect the under-net white water pump to the flushing tank or to the pulping white water multi-pan. A switching valve assembly is provided between the flushing tank pipeline, the parallel pipeline, and the white water pipeline. The parallel pipeline enables the flushing tank to switch between the flushing tank and the pulping tank. The water supply pump delivers white water to the flushing tank or the white water pan for pulping. Parallel pipelines allow the offline white water pump to also deliver white water to the pulping white water pan or flushing tank. A switching valve assembly facilitates control of the parallel pipeline's connectivity, as well as the connection between the flushing tank pipeline and the flushing tank itself, and between the offline white water pump and the pulping white water pan. Depending on requirements, the system can simultaneously operate the flushing tank water supply pump and the offline white water pump, or operate them individually. This effectively reduces the additional water and electricity consumption, lowering production costs. Furthermore, production can continue independently using the flushing tank water supply pump or the offline white water pump, ensuring production efficiency.

[0005] In the aforementioned energy-saving system for integrated pump-line process, the switching valve assembly includes a first switching valve installed on the flushing tank pipeline, a second switching valve installed on the parallel pipeline, and a third switching valve installed on the white water pipeline. The first switching valve controls the connection between the flushing tank water supply pump and the flushing tank, the second switching valve controls the connection between the flushing tank pipeline and the white water pipeline, ensuring the water supply effect to the flushing tank and the pulping white water pan when using a single water supply pump, and the third switching valve controls the connection between the downstream white water pump and the pulping white water pan.

[0006] In the above-mentioned energy-saving system for integrated line pump process, the first switching valve, the second switching valve, and the third switching valve are all on / off valves, which can facilitate users to control the first switching valve, the second switching valve, and the third switching valve according to their needs, thereby reducing production costs and ensuring production stability.

[0007] In the aforementioned energy-saving system for integrated pump-line processes, the first switching valve is located at the end of the flushing tank pipeline near the flushing tank water supply pump, and the third switching valve is located at the end of the white water pipeline near the net-side white water pump. When only the flushing tank water supply pump is activated, the first and second switching valves are opened, and the third switching valve is closed, enabling the flushing tank water supply pump to supply water to the flushing tank and the multiple white water pans for pulping. When only the net-side white water pump is activated, the third and second switching valves are opened, and the first switching valve is closed, enabling the net-side white water pump to supply water to the flushing tank and the multiple white water pans for pulping.

[0008] In the above-mentioned energy-saving system for integrated line pump process, one end of the parallel pipeline is connected to the end of the flushing tank pipeline away from the flushing tank water supply pump, and the other end of the parallel pipeline is connected to the end of the white water pipeline away from the net white water pump. The parallel pipeline enables the flushing tank pipeline and the white water pipeline to be connected, thereby allowing the flushing tank water supply pump or the net white water pump to supply water to the flushing tank and the pulping white water multi-pan.

[0009] In the above-mentioned energy-saving system for integrated line pump process, a first flow regulating component is provided at the end of the grouting tank pipeline near the grouting tank.

[0010] In the above-mentioned energy-saving system for integrated line pump process, the first flow regulating component includes a first flow meter installed at one end of the slurry flushing tank pipeline near the first switching valve or the second switching valve, and a first electric regulating valve is provided on the side of the first flow meter near the slurry flushing tank.

[0011] In the above-mentioned energy-saving system for integrated line pump process, a second flow regulating component is provided at the end of the white water pipeline near the pulping white water multi-disc.

[0012] In the above-mentioned energy-saving system for integrated line pump process, the second flow regulating component includes a second flow meter installed at one end of the white water pipeline near the second or third switching valve, and a second electric regulating valve is provided on the side of the second flow meter near the pulping white water multi-pan.

[0013] In the above-mentioned energy-saving system for integrated line pump process, the white water tank under the net has a white water volume chamber, the upper end of the white water tank has a white water inlet end, and the side of the white water tank has a white water outlet end. The white water outlet end is connected in parallel with the slurry flushing tank water supply pump and the white water pump under the net through a connecting pipeline. The white water volume chamber can easily accommodate the white water flowing in from the white water inlet end, and the white water outlet end can supply water to the slurry flushing tank water supply pump and / or the white water pump under the net through the connecting pipeline.

[0014] Compared with existing technologies, the advantages of this utility model are: 1. By using parallel pipelines and switching valve assemblies, the slurry flushing tank water supply pump or the net water pump can simultaneously supply water to the slurry flushing tank and the pulping white water pan, reducing production costs; 2. The switching valve assembly allows for control of the switching valve's opening status according to usage requirements, ensuring effective water replenishment. 3. The first and second flow regulating components allow users to easily observe and control the flow rate of the slurry tank pipeline and the white water pipeline, ensuring the water replenishment effect.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Example 1 like Figure 1 As shown, this integrated pump-line process energy-saving system includes a white water tank 1. A flushing tank water supply pump 2 and a white water pump 3 are connected in parallel on one side of the white water tank 1. The flushing tank water supply pump 2 is connected to the flushing tank 4 via a flushing tank pipeline 21. The white water pump 3 is connected to the pulping white water multi-pan 5 via a white water pipeline 31. A parallel pipeline 6 is provided between the flushing tank pipeline 21 and the white water pipeline 31, which can connect the white water pump 3 to the flushing tank 4 or the flushing tank water supply pump 2 to the pulping white water multi-pan 5. A switching valve assembly 7 is provided between the flushing tank pipeline 21, the parallel pipeline 6, and the white water pipeline 31. The parallel pipeline 6 enables the flushing tank water supply pump 2 to transfer white water to the flushing tank 4. Alternatively, the water can be transferred from the pulping white water pan 5 to the pulping white water pan 5 or the slurry flushing tank 4 via the parallel pipeline 6. The switching valve assembly 7 can easily control the connection status of the parallel pipeline 6, as well as the connection status between the slurry flushing tank pipeline 21 and the slurry flushing tank 4, and the connection status between the slurry flushing water pump 3 and the pulping white water pan 5. It can select to simultaneously turn on the slurry flushing tank water supply pump 2 and the slurry flushing water pump 3, or turn on the slurry flushing tank water supply pump 2 / slurry flushing water pump 3 alone, which can effectively reduce the additional effects of water and electricity, reduce production costs, and can continue production by using the slurry flushing tank water supply pump 2 / slurry flushing water pump 3 alone, ensuring production efficiency.

[0019] Specifically, the switching valve assembly 7 includes a first switching valve 71 installed on the slurry flushing tank pipeline 21, a second switching valve 72 installed on the parallel pipeline 6, and a third switching valve 73 installed on the white water pipeline 31. The first switching valve 71 can control the connection between the slurry flushing tank water supply pump 2 and the slurry flushing tank 4. The second switching valve 72 can control the connection between the slurry flushing tank pipeline 21 and the white water pipeline 31, ensuring the water supply effect to the slurry flushing tank 4 and the pulping white water pan 5 when using a single water supply pump. The third switching valve 73 can control the connection between the net-side white water pump 3 and the pulping white water pan 5.

[0020] Among them, the first switching valve 71, the second switching valve 72 and the third switching valve 73 are all on / off valves, which can facilitate users to control the first switching valve 71, the second switching valve 72 and the third switching valve 73 according to their needs, thereby reducing production costs and ensuring production stability.

[0021] like Figure 1As shown, the first switching valve 71 is located at the end of the slurry flushing tank pipeline 21 near the slurry flushing tank water supply pump 2, and the third switching valve 73 is located at the end of the white water pipeline 31 near the net-side white water pump 3. When only the slurry flushing tank water supply pump 2 is turned on, the first switching valve 71 and the second switching valve 72 are opened, and the third switching valve 73 is closed, so that the slurry flushing tank water supply pump 2 can supply water to the slurry flushing tank 4 and the pulping white water multi-pan 5; and when only the net-side white water pump 3 is turned on, the third switching valve 73 and the second switching valve 72 are opened, and the first switching valve 71 is closed, so that the net-side white water pump 3 can supply water to the slurry flushing tank 4 and the pulping white water multi-pan 5.

[0022] Furthermore, one end of the parallel pipeline 6 is connected to the end of the flushing tank pipeline 21 away from the flushing tank water supply pump 2, and the other end of the parallel pipeline 6 is connected to the end of the white water pipeline 31 away from the net white water pump 3. Through the parallel pipeline 6, the flushing tank pipeline 21 and the white water pipeline 31 can be connected, so that the flushing tank water supply pump 2 or the net white water pump 3 can supply water to the flushing tank 4 and the pulping white water multi-pan 5.

[0023] The white water tank 1 under the net has a white water volume chamber 11. The upper end of the white water tank 1 has a white water inlet end 12 and the side of the white water tank 1 has a white water outlet end 13. The white water outlet end 13 is connected in parallel with the slurry tank water supply pump 2 and the white water pump 3 under the net through the connecting pipe 10. The white water volume chamber 11 can easily accommodate the white water flowing in from the white water inlet end 12. The white water outlet end 13 can supply water to the slurry tank water supply pump 2 and / or the white water pump 3 under the net through the connecting pipe 10.

[0024] Example 2 This embodiment is basically the same as embodiment one in structure and working principle, except that, as follows: Figure 2 As shown, a first flow regulating component 8 is provided at one end of the flushing tank pipeline 21 near the flushing tank 4. The first flow regulating component 8 includes a first flow meter 81 located at one end of the flushing tank pipeline 21 near the first switching valve 71 or the second switching valve 72. A first electric regulating valve 82 is provided on the side of the first flow meter 81 near the flushing tank 4. Water is supplied to the flushing tank 4 and the pulping white water multi-pan 5 by the flushing tank water pump 2, which can save equipment costs. The flow rate of the flushing tank pipeline 21 can be easily observed by the first flow meter 81, and the flow rate of white water to the flushing tank 4 and the pulping white water multi-pan 5 can be adjusted by controlling the first electric regulating valve 82.

[0025] Example 3 This embodiment is basically the same as embodiment one in structure and working principle, except that, as follows: Figure 3As shown, a second flow regulating component 9 is provided at one end of the white water pipeline 31 near the pulping white water multi-pan 5. The second flow regulating component 9 includes a second flow meter 91 located at one end of the white water pipeline 31 near the second switching valve 72 or the third switching valve 73. A second electric regulating valve 92 is provided on the side of the second flow meter 91 near the pulping white water multi-pan 5. Water is replenished to the pulping tank 4 and the pulping white water multi-pan 5 by the white water pump 3, which can save equipment costs. The flow rate of the white water pipeline 31 can be easily observed through the second flow meter 91, and the flow rate of white water to the pulping white water multi-pan 5 and the pulping tank 4 can be adjusted by controlling the second electric regulating valve 92.
