Description

Technical Field

[0001] This utility model relates to the field of industrial cleaning equipment technology, specifically to a novel spray cleaning water flow reverse compensation energy-saving device. Background Technology

[0002] Spray cleaning water flow reverse replenishment energy-saving equipment is a device that reduces clean water consumption and wastewater discharge by recovering and reversing the flow of water that can be reused during the spray cleaning process, thereby achieving energy and water conservation.

[0003] A search revealed the following publication (announcement) number: CN220460251 U, entitled: "A Combined High-Efficiency Spray Flushing System," comprising a water inlet pipe, a cantilever frame, a cantilever, and a drive device; the cantilever frame is rotatably mounted below the water inlet pipe via a rotary joint, etc.; this utility model, by employing a rotating arm structure, can reduce the number of nozzles and electric valves, thereby saving flushing water and reducing power consumption; furthermore, by setting clockwise and counterclockwise nozzles tilted in two directions, the clockwise or counterclockwise rotation of the cantilever can control the opening of the corresponding nozzles, achieving directional cleaning of the dust collector.

[0004] The above technical solution has the following shortcomings;

[0005] The above-mentioned solution has many technical defects in actual use. The system lacks a dynamic water flow back-compensation mechanism. When the spray pressure fluctuates due to workpiece obstruction or pipeline losses, it cannot replenish the flow through the auxiliary channel in real time, which easily creates local cleaning blind spots and results in a low cleaning qualification rate. At the same time, its water circulation system has insufficient filtration layers, limited cleaning wastewater recovery rate, and large water consumption. Moreover, the spray pump is not equipped with load adaptive frequency conversion control, and still maintains high energy consumption under low load conditions, resulting in serious energy waste. It is difficult to meet the requirements of industrial green production for water conservation, energy saving and cleaning stability. In addition, the system does not integrate a waste heat recovery device, the heat energy utilization rate during the heating of the cleaning fluid is low, and the automatic adjustment capability is limited. It cannot adaptively adjust the spray parameters according to the workpiece material and size. Reliance on manual operation easily leads to unstable cleaning effect. The above problems are more prominent, especially for complex structure workpieces or high-precision cleaning requirements, which restricts the improvement of the equipment in terms of energy saving, environmental protection and applicability.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model discloses a novel energy-saving spray cleaning water flow reverse compensation device.

[0030] This utility model provides, for example Figure 1-4 The novel spray cleaning water flow reverse compensation energy-saving device shown includes a base 1, a stainless steel sealed cleaning chamber 2 fixedly connected to one top end of the base 1, a support plate 3 fixedly connected to the other top end of the base 1, a filter device 4 fixedly connected to the bottom side wall of the support plate 3, a plate heat exchanger 5 fixedly connected to the top side wall of the support plate 3, a rotatable spray arm 6 fixedly connected to both ends, the top and the rear side wall of the stainless steel sealed cleaning chamber 2, and a water tank 7 fixedly connected to the top of the stainless steel sealed cleaning chamber 2.

[0031] A spray pump assembly 8 is fixedly connected to the output end of water tank 7. A dynamic reverse compensation control module 9 is fixedly connected to one end of the output pipe of spray pump assembly 8. A water supply pipe 10 is fixedly connected inside the cavity of stainless steel sealed cleaning chamber 2. The output end of dynamic reverse compensation control module 9 and the other end of spray pump assembly 8 are both fixedly connected to the input end of water supply pipe 10. A conical water collection port 11 is provided inside the cavity of stainless steel sealed cleaning chamber 2, and a separation support mesh plate 12 is fixedly connected thereto. A delivery pump assembly 13 is fixedly connected to the bottom of stainless steel sealed cleaning chamber 2. A filter connection bottom cover 14 is threadedly connected to the output pipe end of delivery pump assembly 13. The top of filter connection bottom cover 14 is threadedly connected to the bottom of filter device 4. The output pipe end of filter device 4 is connected to a plate heat exchanger. The hot water inlet of the heat exchanger 5 is fixedly connected, and both ends of the water tank 7 are fixedly connected to connecting pipes 15. The other ends of the connecting pipes 15 are fixedly connected to the hot water outlet and cold water outlet of the plate heat exchanger 5, respectively. The input end of each rotatable spray arm 6 is fixedly connected to the output end of the water supply pipe 10. The stainless steel sealed cleaning chamber 2 is made of stainless steel, which has good corrosion resistance and sealing performance to prevent sewage leakage during the cleaning process, and at the same time provides a closed space for the cleaning operation. The supporting plate 3 provides an installation carrier for the filter device 4 and the plate heat exchanger 5, making its layout reasonable and saving space. The filter device 4 can filter the circulating water to remove impurities and ensure the quality of the cleaning water. The plate heat exchanger 5 can recover waste heat from the cleaning water. Energy reuse is achieved by connecting the cold water inlet of the plate heat exchanger 5 to the new water pipe, reducing energy consumption. The rotatable spray arms 6, a feature of existing technology (mainly composed of a rotary drive mechanism, spray arm body, and water circuit rotary sealing device), can rotate at multiple angles, expanding the spray range and reducing cleaning blind spots. The water tank 7 stores clean water to provide a water source for the spraying. The spray pump assembly 8 provides power to the spraying, ensuring spray pressure. The dynamic reverse compensation control module 9 dynamically adjusts the water flow according to the spray pressure and flow rate, achieving reverse compensation and improving water resource utilization. The water supply pipeline 10 delivers water to each rotatable spray arm 6. To ensure continuous spraying, the cone-shaped water inlet 11 facilitates wastewater collection and improves wastewater recovery efficiency. The separation support mesh plate 12 separates cleaning materials from wastewater, preventing impurities from clogging the pipes. The conveying pump assembly 13 transports wastewater to the filtration device 4 for treatment, achieving water recycling. The filter connection bottom cover 14 facilitates disassembly and cleaning of filter impurities. The connecting pipe 15 enables water supply circulation between the water tank 7 and the plate heat exchanger 5. This solves the problems of existing spray cleaning devices, such as lack of dynamic water flow back compensation, insufficient water circulation filtration layers, no-load adaptive frequency conversion of the spray pump, lack of waste heat recovery, and weak automatic adjustment, resulting in many cleaning blind spots, low pass rate, high resource and energy consumption, and unstable effect.

[0032] To improve the sealing and noise reduction of the equipment, such as Figure 1 and 2 As shown, the side wall of the stainless steel sealed cleaning chamber 2 is rotatably connected to a sealing door assembly 16 via a hinge. Both the stainless steel sealed cleaning chamber 2 and the side wall cavity of the sealing door assembly 16 are equipped with a sound-absorbing cotton filling layer 17. The sealing door assembly 16 enhances the sealing performance of the stainless steel sealed cleaning chamber 2, preventing water vapor and noise from leaking out during the cleaning process. The sound-absorbing cotton filling layer 17 effectively absorbs the noise generated during equipment operation, reduces the impact on the surrounding environment, and improves the working environment.

[0033] To improve the water circulation filtration effect and ensure the quality of the cleaning water, such as Figure 2 and 3 As shown, the filtration device 4 includes a tank 18. Inside the tank 18, a stainless steel filter screen 19, a PP cotton filter element 20, and an activated carbon adsorption column 21 are fixedly connected sequentially from bottom to top. A backwashing device 22 is fixedly connected to the top of the tank 18. The stainless steel filter screen 19 filters larger particles of impurities in the water, the PP cotton filter element 20 further filters finer impurities, and the activated carbon adsorption column 21 adsorbs odors and organic matter in the water. This three-layer filtration improves water purity. The backwashing device 22, being an existing technology, allows for periodic backwashing of the filtration components, removing impurities from the filter media, extending the service life of the filtration components, and ensuring stable filtration performance.

[0034] To expand the spraying range and reduce blind spots in cleaning, such as Figure 4 As shown, each rotatable spray arm 6 has 12 fan-shaped nozzles 23 fixedly connected to its side wall. With the reasonable distribution of the 12 fan-shaped nozzles 23 and the rotation of the rotatable spray arm 6, the items in the cleaning chamber can be sprayed in all directions, with a wide coverage area, effectively reducing cleaning blind spots and improving the cleaning qualification rate.

[0035] To facilitate the removal of filtered impurities and ensure the normal operation of the equipment, such as Figure 1 and 2 As shown, a sewage pump 24 is fixedly connected to the bottom of the filter connection bottom cover 14 through an opening. The sewage pump 24 can be used to discharge the impurities accumulated in the filter connection bottom cover 14 in a timely manner, prevent impurities from clogging the pipes, ensure the smooth flow of the water circulation system, and reduce the number of equipment maintenance.

[0036] To achieve automated adjustment and energy-saving operation of equipment, such as Figure 2As shown, the spray pump assembly 8 includes a spray pump body and a load adaptive frequency conversion system. The vector frequency converter of the load adaptive frequency conversion system is electrically connected to the motor of the spray pump body. The dynamic reverse compensation control module 9 includes a pressure sensor, an electromagnetic flow control valve, and a reverse compensation auxiliary pipeline. The pressure sensor is installed at the input end of the water supply pipeline 10. The electromagnetic flow control valve is connected to the PLC module of the intelligent control system via a 485 bus. A PLC display controller 25 is fixedly connected to the side wall of the stainless steel sealed cleaning chamber 2. The load adaptive frequency conversion system is used to adjust the speed of the spray pump according to the load change, reducing energy consumption. The dynamic reverse compensation control module 9 monitors the pressure through the pressure sensor and adjusts the flow through the electromagnetic flow control valve to achieve dynamic reverse compensation of water flow and ensure stable spraying effect. The PLC display controller 25 is used to facilitate operators to monitor the equipment operating status, realize automated adjustment, and improve the ease of equipment operation.

[0037] To enhance the corrosion resistance of equipment and extend its service life, such as Figure 2 and 3 As shown, the interior of the tank 18 and the surface of the stainless steel filter screen 19 are both provided with a Cr3+ passivation anti-corrosion coating. The Cr3+ passivation anti-corrosion coating can effectively improve the corrosion resistance of the tank 18 and the stainless steel filter screen 19, resist the erosion of chemicals in sewage, extend the service life of the equipment, and reduce maintenance costs.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
