Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a reclaimed water recycling pump which is convenient for sampling and measuring. Background Art

[0002] A reclaimed water reuse system is one that treats municipal or industrial wastewater, meeting certain water quality standards, for non-potable uses. These uses include urban landscaping, irrigation, toilet flushing, and industrial cooling water, reducing fresh water consumption and environmental pollution. Reclaimed water reuse systems typically include pretreatment, biological treatment, advanced treatment, disinfection, and distribution. The pretreatment unit removes large particles and suspended solids, while the biological treatment unit degrades organic pollutants through microbial action. The advanced treatment unit further removes fine particles and certain soluble pollutants. The disinfection unit eliminates pathogens to ensure water quality, and the distribution unit delivers the treated water to designated points of use.

[0003] In a reclaimed water reuse system, the intake pump is a key component responsible for extracting the required amount of water from treated water for reuse. Existing intake pumps, when used in reclaimed water reuse systems, have poor regulation capabilities and are unable to quickly switch to connect to different water sources for water intake. Furthermore, when extracting water, some reclaimed water containing a large amount of impurities requires the installation of a corresponding filtration structure. However, this filtration structure is inconvenient to replace and clean after a period of use.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a reclaimed water reuse pump that is convenient for sampling and measurement. Utility Model Content

[0005] The purpose of the utility model is to provide a water pump for recycling water that is convenient for sampling and measuring, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water pump for recycling recycled water that is convenient for sampling and measuring, comprising a motor, a pump body, a water inlet pipe, and a water outlet pipe; the output end of the motor is rotatably connected to the pump body through a transmission shaft, so as to drive the pump body to circulate, a water inlet pipe is connected to one side of the pump body, and a water outlet pipe is connected to the top side. When the pump body is running, the water inlet pipe is connected to the recycled water source, and then the recycled water is transferred into the pump body under the pumping suction of the pump body, and then taken out through the water outlet pipe. A group of base plates are fixedly installed at the bottom of the motor, and the base plates are connected to the fixed base through a rotating connecting piece, and the fixed base is fixed by bolts and other fixing pieces. Then, under the action of the rotating connecting piece, the motor can be rotated to adjust the placement angle position of the water outlet pipe and the water inlet pipe on both sides of the pump body, so as to adjust the recycled water source and water intake at different positions. Adaptive connection, a group of ultrasonic flow meters are set on the outlet pipe, and the measuring end of the ultrasonic flow meter extends to the inside of the outlet pipe, and the flow rate of the reclaimed water flowing inside the outlet pipe is automatically detected to ensure fast and efficient quantitative sampling. At the same time, a group of filter boxes are set on the water inlet pipe, and the inside of the filter box is connected to the inside of the water inlet pipe on both sides. A filtration structure is detachably installed inside the filter box. The reclaimed water flowing along the inside of the water inlet pipe passes through the filtration structure for filtration, and then is transferred into the pump body, and then output through the outlet pipe. The filtration structure is mainly used to filter some large particles of impurities in the reclaimed water to prevent it from entering the inside of the pump body and causing blockage, damage and other faults. The filtration structure is disassembled and installed along the top of the filter box to facilitate its cleaning and replacement, which increases the service life of the filtration structure and the filtration purity of the reclaimed water.

[0007] Compared with the prior art, the beneficial effects of the present invention are: by arranging a set of filter boxes on the water inlet pipe, and then detachably installing the filter structure inside the filter box, the water can be filtered to prevent blockage inside the pump body;

[0008] By installing an ultrasonic flow meter on the outlet pipe, quantitative sampling of reclaimed water can be achieved, which increases the accuracy of sampling;

[0009] By arranging a rotating column at the bottom of the motor and connecting it with a rotating groove for rotation, it is convenient to adjust the use angle of the water outlet pipe and the water inlet pipe so that it can be connected with the reclaimed water source and sample equipment in different directions, thereby increasing the scope of use.

Adaptive connection, a group of ultrasonic flow meters 19 are provided on the water outlet pipe 17, and the measuring end of the ultrasonic flow meter 19 extends to the inside of the water outlet pipe 17, and the flow rate of the reclaimed water flowing inside the water outlet pipe 17 is automatically detected to ensure fast and efficient quantitative sampling. At the same time, a group of filter boxes 20 are provided on the water inlet pipe 18, and the inner sides of the filter box 20 are connected to the inside of the water inlet pipe 18. A filter structure is detachably installed inside the filter box 20. The reclaimed water flowing along the inside of the water inlet pipe 18 passes through the filter structure for filtration, and then is transferred to the pump body 11, and then output through the water outlet pipe 17. The filter structure is mainly used to filter some large particles of impurities in the reclaimed water to prevent it from entering the inside of the pump body 11 and causing blockage, damage and other faults. The filter structure is disassembled and installed along the top of the filter box 20, which is convenient for cleaning and replacement, that is, to increase the service life and filtration purity of the reclaimed water filtration of the filter structure.

[0021] In the embodiment of the present invention, the filter box 20 is configured as a rectangular structure, with through holes on both sides of its interior and respectively connected to the water inlet pipes 18 on both sides. A split push-pull split box cover 28 is provided on the top of the water inlet pipe 18 to maintain the seal of the top of the filter box 20.

[0023] In one embodiment of the present invention, for the ultrasonic flowmeter 19, its operating principle is based on the speed difference caused by the flow of fluid when ultrasonic waves pass through the fluid. It is mainly composed of an ultrasonic transmitter, a receiver, an electronic circuit and a flow display system. In the ultrasonic flowmeter, the ultrasonic transmitter and receiver are usually installed on both sides of the fluid pipeline. When the fluid is still, the ultrasonic waves emitted from both sides of the pipeline propagate along the same path and are received by the other receiver with the same propagation time. When the fluid flows, the propagation speed of the ultrasonic waves in the downstream direction will increase, and the propagation speed in the upstream direction will slow down. Therefore, the time for the ultrasonic waves in the two directions to reach the other receiver will be different, forming a time difference. By measuring this time difference, combined with the known propagation speed of the ultrasonic waves in the fluid, the average flow velocity of the fluid can be calculated, and then the flow value can be obtained.

[0024] As a preferred embodiment of the present invention, the rotating connecting member includes a rotating column 14 fixed to the bottom middle part of the base plate 13, and the bottom of the rotating column 14 is rotatably connected to a rotating groove 15 opened inside the top of the fixed base 16. The vertical sections of the rotating column 14 and the rotating groove 15 are both set to an inverted T-shaped structure, which is used to maintain stable rotation of the two while being in a limited state in the vertical direction, that is, by pushing the motor 10, the placement angle of the water outlet pipe 17 and the water inlet pipe 18 can be directly adjusted, thereby increasing the adjustment ability.

[0025] As a preferred embodiment of the present invention, the filtering structure includes multiple filter screens 21 distributed at intervals. The filter screens 21 are parallel to each other and perpendicular to the flow direction of the reclaimed water inside the water inlet pipe 18. A circle of filter screen frames 24 are installed on the outside of the filter screens 21. The tops of the multiple groups of filter screen frames 24 are slidably connected to a mounting plate 25. A horizontally distributed slide rail 26 is opened in the middle of the mounting plate 25. A slider is fixedly installed on the top middle of the filter screen frame 24. The slider is slidably connected along the inside of the slide rail 26. That is, under the action of the sliding connection between the slider and the slide rail 26, the distance between adjacent filter screens 21 is adjusted, so that an appropriate number of filter screens 21 are installed at the bottom of the mounting plate 25 to filter the reclaimed water.

[0026] Multiple groups of filter screens 21 are arranged along the flow direction of the reclaimed water inside the water inlet pipe 18, and their apertures gradually decrease, thereby performing multi-stage filtration on the reclaimed water;

[0027] Two positioning pins 22 are symmetrically installed on both sides of the bottom of the filter frame 24. The bottom of the filter box 20 corresponding to the positioning pins 22 is provided with positioning holes 23 distributed horizontally and evenly spaced. After the filter 21 is adjusted to a suitable position, the positioning pins 22 are plugged into the positioning holes 23 to fix the filter 21.

[0028] As a preferred embodiment of the present invention, in order to keep the filter screen 21 able to fully filter the flowing grey water after positioning, a buffer sealing plate 27 is installed on the top of the filter frame 24. The buffer sealing plate 27 has a certain buffering property. After the buffer sealing plate 27 is placed inside the filter box 20, the split box cover 28 is pushed to close the top of the filter box 20, and downward pressure is applied to the buffer sealing plate 27 to maintain full contact between the top of the filter frame 24 and the bottom of the split box cover 28, thereby preventing grey water from passing over the top of the filter frame 24.

[0029] The working principle of the present invention is as follows: in the idle position of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in a working order. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process, and does not explain the electrical control. During operation, the water inlet pipe 18 is connected to the water source in the reclaimed water reuse system, and the water outlet pipe 17 is connected to the equipment to be sampled and transferred. Prior to this, the water outlet pipe 17 and the water inlet pipe 18 are connected by rotating the ultrasonic flowmeter 19 under the rotation connection of the rotating column 14 and the rotating tank 15. Adjust to a suitable angle, and then after connecting the outlet pipe 17 and the inlet pipe 18 to the corresponding equipment, install a suitable number of filters 21 inside the filter box 20. When installing the filter 21, directly control the mounting plate 25 to drive the positioning pins 22 at the bottom of the filter frame 24 to plug into the corresponding positioning holes 23, and then push the split box covers 28 on both sides to move relative to each other, and then apply downward pressure to the buffer sealing plate 27 on the top of the filter frame 24 to control the stability of the filter frame 24, and then use the fastening bolts and the bolt plate 29 to fix the split box cover 28 to the top of the filter box 20, and filter the large particles of impurities in the reclaimed water through the filter 21.
