Description

Technical Field

[0001] This application relates to water supply equipment for the food processing industry, and more particularly to a water supply system. Background Technology

[0002] In the food processing industry, traditional water supply systems typically use electric water pumps as their power source. However, prolonged operation in humid environments can easily lead to a decline in the insulation performance of the motor, resulting in problems such as leakage and short circuits. In addition, residue generated during food processing can easily clog the water pump filter, requiring frequent shutdowns for cleaning.

[0003] Currently, the mainstream solutions include: using motors with IP68 protection rating, but their manufacturing cost is high; adding multi-layer filters to the water pump inlet can reduce clogging, but it is not convenient for people to clean them, and it will increase water flow resistance after long-term use. In order to solve the above problems, a water supply system has been proposed. Utility Model Content

[0004] The purpose of this application is to provide a water supply system that has advantages such as low cost and cleaning function, and solves the problems of traditional water supply systems being prone to motor failure in humid environments, inconvenient cleaning after filter clogging, and increased water flow resistance after long-term use.

[0005] The water supply system provided in this application adopts the following technical solution: it includes a pneumatic pump and a filter housing. The pneumatic pump is provided with an inlet pipe and a drain pipe at its input end and output end, respectively. A bottom cover is installed and connected to the bottom of the filter housing. The inlet pipe passes through the bottom of the bottom cover and is fixedly connected thereto. An external water pipe is fixedly connected to the side of the filter housing. A top mounting frame is fixedly connected to the top of the filter housing. An mounting plate is installed inside the top mounting frame. A fixing ring and a supporting filter cylinder are fixedly connected to the bottom of the bottom cover. The supporting filter cylinder is inside the fixing ring. A filter element is fitted on the surface of the supporting filter cylinder. A rotating shaft is tightly nested inside the mounting plate via a bearing. A second knob and a circular plate are fixedly connected to the top and bottom of the rotating shaft, respectively. The second knob is located at the top of the mounting plate. Multiple uprights are fixedly connected to the outer side of the bottom of the circular plate. The uprights are located outside the filter element. Multiple cleaning brushes are fixedly connected to the side of the uprights. One side of the cleaning brush overlaps the outer side of the filter element. By adopting the above technical solution and setting a pneumatic pump as the power source, the short circuit and leakage faults that may occur when traditional motors are running in humid environments can be avoided, which can reduce the maintenance cost and safety hazards of the equipment. By setting a filter element, the water flow can be filtered to intercept impurities in the water. The setting of the filter cylinder can provide stable support for the filter element and prevent it from deforming or shifting under the impact of water flow. When the filter element needs to be cleaned, the operator only needs to rotate the second knob to drive the rotating shaft and the circular plate to rotate, which in turn causes the cleaning brush on the side of the upright to rotate on the outside of the filter element, so as to clean the impurities attached to the surface of the filter element. The cleaning work can be completed without disassembling the filter element, which greatly improves the convenience of cleaning. The cleaned impurities will be deposited at the bottom of the cover under the action of gravity.

[0006] Preferably, a conical hopper is fixedly connected to each of the four corners of the bottom of the bottom cover, and a drain valve is fixedly connected to the bottom of the conical hopper; By adopting the above technical solution, and by setting up a conical bucket and a drain valve, the cleaned impurities can be concentrated in the conical bucket. When it is necessary to discharge the impurities, the operator only needs to open the drain valve, and the impurities in the conical bucket will be quickly discharged under the flushing action of the water flow. There is no need to manually clean the inside of the bottom cover, which can improve the convenience of equipment maintenance.

[0007] Preferably, the mounting plate has triangular extrusion grooves on all four sides, and the inner wall of the top mounting frame has shrinkage grooves on all four sides. A rotating rod is tightly nested inside the shrinkage groove via a bearing. A threaded rod is fixedly connected to one end of the rotating rod. A threaded cylinder is threadedly connected to the surface of the threaded rod. A triangular extrusion block is fixedly connected to the surface of the threaded cylinder. One side of the triangular extrusion block slides through the shrinkage groove and is engaged in the triangular extrusion groove. By adopting the above technical solution, and by setting up a triangular extrusion groove, a shrinkage groove, a rotating rod, a threaded rod, a threaded cylinder, and a triangular extrusion block, when the mounting plate needs to be installed, the mounting plate is placed in the top mounting frame, and then the rotating rod is rotated, which drives the threaded rod to rotate. This allows the threaded cylinder to move along the axial direction of the threaded rod, thereby pushing the triangular extrusion block into the triangular extrusion groove. Utilizing the stability of the triangular structure, the mounting plate can be quickly snapped and fixed to the top mounting frame, avoiding the tedious operation of tightening each bolt individually, thus improving installation efficiency. At the same time, when it is necessary to disassemble the mounting plate, simply rotating the rotating rod in the opposite direction will allow the triangular extrusion block to exit from the triangular extrusion groove, thus achieving convenient disassembly of the mounting plate.

[0008] Preferably, a transmission rod is tightly nested inside the top of the shrinkage groove via a bearing, and a first knob and a worm are fixedly connected to the top and bottom of the transmission rod, respectively. A worm wheel is fixedly connected to the surface of the rotating rod, and the worm and the worm wheel mesh with each other. By adopting the above technical solution, and by setting up a transmission rod, worm, worm wheel and first knob, when it is necessary to rotate the rotating rod, the first knob can be rotated directly to drive the transmission rod and worm to rotate synchronously. Through the meshing transmission of the worm and worm wheel, the rotational motion is transmitted to the rotating rod without direct contact with the rotating rod located in the shrinkage groove, which is convenient to operate. At the same time, by utilizing the self-locking characteristics of the worm gear transmission, the triangular extrusion block can be prevented from loosening due to external force during use.

[0009] Preferably, a slide rod is fixedly connected to the inner side of the shrinkage groove, and a slide cylinder is fixedly connected to the inside of the triangular extrusion block, with the slide rod slidably connected to the slide cylinder; By adopting the above technical solution, and by setting up a sliding rod and a sliding cylinder, when the triangular extrusion block moves horizontally under the push of the rotating rod, the sliding cylinder will slide synchronously along the sliding rod, thereby guiding and limiting the movement trajectory of the triangular extrusion block, and ensuring that the triangular extrusion block can accurately enter or exit the triangular extrusion groove.

[0010] Preferably, a top sealing ring is fixedly connected to the bottom of the mounting plate, and a bottom sealing ring is fixedly connected to the bottom inside the top mounting frame, with the bottom of the top sealing ring overlapping the top of the bottom sealing ring. By adopting the above technical solution and setting a top sealing ring and a bottom sealing ring, after the mounting plate and the top mounting frame are connected and installed, the top sealing ring will fit tightly with the bottom sealing ring, forming a double sealing structure, thereby enhancing the sealing performance of the installation part.

[0011] Preferably, handles are fixedly connected to both opposite sides of the top of the mounting plate; By adopting the above technical solution and by setting a handle, operators can directly grasp the handle to apply force when installing or removing the mounting plate without the need for additional tools.

[0012] Preferably, the pneumatic pump is fixedly connected to support feet on both sides of its bottom, the filter housing is fixedly connected to fixing plates on both sides of its surface, the fixing plates are fixedly connected to support feet at their bottoms, and the filter housing is provided with an observation window. By adopting the above technical solution and setting support feet, a support structure can be provided for the device, and the observation window makes it easy for people to observe the inside of the filter shell.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. This water supply system, by using a pneumatic pump as a power source, avoids the short circuits and leakage problems that may occur when traditional motors operate in humid environments, thus reducing equipment maintenance costs and safety hazards. The filter cartridge filters the water flow and intercepts impurities. The support for the filter cartridge provides stable support, preventing deformation or displacement under water flow impact. When cleaning the filter cartridge, the operator simply rotates the second knob, causing the shaft and circular plate to rotate, which in turn causes the cleaning brush on the side of the upright to rotate on the outside of the filter cartridge, cleaning the impurities attached to the surface without disassembling the filter cartridge, greatly improving cleaning convenience. The cleaned impurities will settle at the bottom of the cover under gravity. The conical hopper and drain valve allow the cleaned impurities to collect in the conical hopper. When it is necessary to discharge impurities, the operator simply opens the drain valve, and the impurities in the conical hopper will be quickly discharged under the flushing action of the water flow, eliminating the need for manual cleaning of the bottom cover and improving equipment maintenance convenience. 2. By incorporating a triangular extrusion groove, shrinkage groove, rotating rod, threaded rod, threaded cylinder, and triangular extrusion block, when installing the mounting plate, the mounting plate is placed in the top mounting frame. Rotating the rotating rod causes the threaded rod to rotate, allowing the threaded cylinder to move axially along the threaded rod, thus pushing the triangular extrusion block into the triangular extrusion groove. Utilizing the stability of the triangular structure, the mounting plate can be quickly and securely fastened to the top mounting frame, avoiding the tedious operation of tightening bolts one by one, thus improving installation efficiency. Simultaneously, when the mounting plate needs to be disassembled, simply rotating the rotating rod in the opposite direction allows the triangular extrusion block to exit from the triangular extrusion groove, enabling convenient disassembly. By incorporating a transmission rod, worm gear, worm wheel, and a first knob, when the rotating rod needs to be rotated, the first knob can be directly rotated, causing the transmission rod and worm gear to rotate synchronously. The rotational motion is transmitted to the rotating rod through the meshing transmission of the worm gear and worm wheel, eliminating the need for direct contact with the rotating rod located in the shrinkage groove, making operation convenient. Furthermore, the self-locking characteristic of the worm gear transmission prevents the triangular extrusion block from loosening due to external forces during use. Attached Figure Description

The pneumatic pump 1 is provided with an inlet pipe 101 and a drain pipe 102 at its input and output ends, respectively. A bottom cover 5 is installed and connected to the bottom of the filter housing 2. The inlet pipe 101 passes through the bottom of the bottom cover 5 and is fixedly connected thereto. An external water pipe 7 is fixedly connected to the side of the filter housing 2. A top mounting frame 203 is fixedly connected to the top of the filter housing 2. A mounting plate 3 is installed and connected inside the top mounting frame 203. A fixing ring 503 and a supporting filter cartridge 504 are fixedly connected to the bottom of the bottom cover 5. The supporting filter cartridge 504 is located inside the fixing ring 503. A filter element 6 is fitted on the surface of the supporting filter cartridge 504. A rotating shaft 303 is tightly nested inside the mounting plate 3 via bearings. A second knob 304 and a circular plate 305 are fixedly connected to the top and bottom of the rotating shaft 303, respectively. The second knob 304 is located at the top of the mounting plate 3. Multiple uprights 306 are fixedly connected to the bottom outer side of the circular plate 305. The uprights 306 are located outside the filter element 6. Multiple cleaning brushes 307 are fixedly connected to the side of the uprights 306. One side of the cleaning brushes 307 overlaps the outside of the filter element 6. By setting a pneumatic pump 1 as the power source, the short circuit and leakage faults that may occur when the traditional motor is running in a humid environment can be avoided, which can reduce the maintenance cost and safety hazards of the equipment. By setting the filter element 6, the water flow can be filtered and impurities in the water can be intercepted. The filter cylinder 504 provides stable support for the filter element 6 and prevents it from deforming or shifting under the impact of water flow. When the filter element 6 needs to be cleaned, the operator only needs to rotate the second knob 304 to drive the rotating shaft 303 and the circular plate 305 to rotate, which in turn causes the cleaning brushes 307 on the side of the uprights 306 to rotate outside the filter element 6, so as to clean the impurities attached to the surface of the filter element 6. The cleaning work can be completed without disassembling the filter element 6, which greatly improves the convenience of cleaning. The cleaned impurities will be... Under the influence of gravity, the sediment settles at the bottom of the bottom cover 5. Conical hoppers 501 are fixedly connected to the four corners of the bottom of the bottom cover 5. Drain valves 502 are fixedly connected to the bottom of the conical hoppers 501. By setting up the conical hoppers 501 and the drain valves 502, the cleaned impurities can be concentrated and collected in the conical hoppers 501. When it is necessary to discharge the impurities, the operator only needs to open the drain valves 502, and the impurities in the conical hoppers 501 will be quickly discharged under the flushing action of the water flow. There is no need for manual cleaning of the inside of the bottom cover 5, which can improve the convenience of equipment maintenance.

[0018] Please see Figure 4 , Figure 5 and Figure 6The mounting plate 3 has triangular extrusion grooves 301 on all four sides, and the inner wall of the top mounting frame 203 has shrinkage grooves 204 on all four sides. A rotating rod 205 is tightly nested inside the shrinkage groove 204 via bearings. One end of the rotating rod 205 is fixedly connected to a threaded rod 206. A threaded cylinder 208 is threadedly connected to the surface of the threaded rod 206, and a triangular extrusion block 209 is fixedly connected to the surface of the threaded cylinder 208. One side of the triangular extrusion block 209 slides through the shrinkage groove 204 and is engaged within the triangular extrusion groove 301. By setting the triangular extrusion groove 301, shrinkage groove 204, rotating rod 205, threaded rod 206, threaded cylinder 208, and triangular extrusion block 209, when the mounting plate 3 needs to be installed, the mounting plate 3 can be... Plate 3 is placed inside the top mounting frame 203. Rotating the rotating rod 205 causes the threaded rod 206 to rotate, allowing the threaded cylinder 208 to move axially along the threaded rod 206. This pushes the triangular extrusion block 209 into the triangular extrusion groove 301. Utilizing the stability of the triangular structure, the mounting plate 3 and the top mounting frame 203 can be quickly snapped together, avoiding the tedious operation of tightening bolts one by one, thus improving installation efficiency. Simultaneously, when the mounting plate 3 needs to be disassembled, rotating the rotating rod 205 in the opposite direction allows the triangular extrusion block 209 to exit from the triangular extrusion groove 301, enabling convenient disassembly of the mounting plate 3. The top of the shrinkage groove 204 is tightly nested with a transmission rod 2 via a bearing. 010, a first knob 2012 and a worm gear 2011 are fixedly connected to the top and bottom of the transmission rod 2010, respectively. A worm wheel 207 is fixedly connected to the surface of the rotating rod 205. The worm gear 2011 and the worm wheel 207 mesh with each other. By setting up the transmission rod 2010, worm gear 2011, worm wheel 207 and first knob 2012, when it is necessary to rotate the rotating rod 205, the first knob 2012 can be directly rotated to drive the transmission rod 2010 and worm gear 2011 to rotate synchronously. Through the meshing transmission of worm gear 2011 and worm wheel 207, the rotational motion is transmitted to the rotating rod 205. There is no need to directly contact the rotating rod 205 located in the shrinkage groove 204, making operation convenient. At the same time, the worm wheel 2011 is used to transmit the rotational motion. The self-locking characteristic of the worm gear 2011 transmission can prevent the triangular extrusion block 209 from loosening due to external force during use. A slide rod 2013 is fixedly connected to the inner side of the shrinkage groove 204, and a slide cylinder 2014 is fixedly connected to the inside of the triangular extrusion block 209. The slide rod 2013 is slidably connected to the slide cylinder 2014. By setting the slide rod 2013 and the slide cylinder 2014, when the triangular extrusion block 209 moves horizontally under the push of the rotating rod 205, the slide cylinder 2014 will slide synchronously along the slide rod 2013, thereby guiding and limiting the movement trajectory of the triangular extrusion block 209, and ensuring that the triangular extrusion block 209 can accurately enter or exit the triangular extrusion groove 301.

[0019] Please see Figure 4 and Figure 6The bottom of the mounting plate 3 is fixedly connected to a top sealing ring 308, and the bottom of the top mounting frame 203 is fixedly connected to a bottom sealing ring 2015. The bottom of the top sealing ring 308 overlaps the top of the bottom sealing ring 2015. By setting the top sealing ring 308 and the bottom sealing ring 2015, when the mounting plate 3 and the top mounting frame 203 are installed together, the top sealing ring 308 will fit tightly with the bottom sealing ring 2015, forming a double sealing structure, which can enhance the sealing performance of the installation part. The top of the mounting plate 3 is fixedly connected to handles 302 on both opposite sides. By setting the handles 302, the operator can directly hold the handles 302 to apply force when installing or removing the mounting plate 3 without the need for additional tools.

[0020] Please see Figure 2 The pneumatic pump 1 has support feet 4 fixedly connected to both sides of its bottom. The filter housing 2 has fixing plates 201 fixedly connected to both sides of its surface. The bottom of the fixing plates 201 is fixedly connected to support feet 4. The surface of the filter housing 2 is provided with an observation window 2016. By setting support feet 4, a support structure can be provided for the device. The observation window 2016 makes it easy for people to observe the inside of the filter housing 2.

[0021] The implementation principle of this application embodiment is as follows: When in use, water is first introduced into the filter shell 2 through the external water pipe 7, and then the pneumatic pump 1 is run. Through the pneumatic device inside, suction is generated, which can draw the filtered water in the filter shell 2 into the pump body, and then the water is transported to the drain pipe 102 through pressure. During this process, the filter components inside the filter housing 2 will intercept impurities in the water to ensure that the water quality entering the pneumatic pump 1 meets the usage requirements. When a lot of impurities are attached to the surface of the filter element 6 and affect the filtration efficiency, the operator can rotate the second knob 304 to drive the rotating shaft 303 and the circular plate 305 to rotate, so that the cleaning brush 307 on the side of the upright 306 rotates on the outside of the filter element 6, which can clean the surface of the filter element 6. The cleaned impurities will sink into the conical hopper 501 at the bottom of the bottom cover 5 under the action of gravity. The impurities can be discharged by opening the drain valve 502 periodically. If the filter element 6 needs to be replaced or deep cleaned, first rotate the first knob 2012, which drives the worm gear 2011 to rotate through the transmission rod 2010. The worm gear 2011 meshes with the worm wheel 207, which can rotate the rotating rod 205 and the threaded rod 206. Through the limiting of the slide rod 2013 and the slide cylinder 2014, the threaded cylinder 208 can move on the surface of the threaded rod 206, which can drive the triangular extrusion block 209 to exit from the triangular extrusion groove 301. Then, hold the handle 302 to remove the mounting plate 3 from the top mounting frame 203, and the filter element 6 can be operated. After completion, install the mounting plate 3 in reverse order to restore operation.
