Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a water pump that can filter and discharge slag. Background Technology

[0002] Water pumps are widely used in many areas of modern industrial production and daily life, including water supply and drainage, industrial processes, agricultural irrigation, and building fire protection. To ensure the normal and efficient operation of water pumps and to avoid problems such as wear and damage to internal parts caused by impurities, filtering the liquid being pumped during operation is an essential and important measure.

[0003] Typically, filters are installed at the water pump inlet or other suitable locations to intercept various impurities mixed in the liquid, such as silt, particulate matter, fibers, and other suspended solids. These filters effectively prevent impurities from entering the water pump, thus protecting the pump, extending its service life, and reducing maintenance costs.

[0004] In practical applications, when the liquid being pumped contains a high level of impurities, these impurities will gradually accumulate on the filter screen over time. Once the impurities accumulate to a certain extent, filter clogging will inevitably occur. Filter clogging significantly increases the resistance of the liquid passing through the filter, leading to a reduction in the water pump's inlet flow rate, affecting the pump's normal operating performance and reducing its efficiency. In severe cases, filter clogging can also cause increased internal pressure in the pump, leading to motor overload and other malfunctions, and may even damage the pump's structure, requiring frequent filter disassembly, cleaning, or replacement. This not only increases maintenance workload but also extends equipment downtime and affects production efficiency. While existing technologies offer water pumps that can discharge impurities without filter disassembly, the filtration structure of these pumps is relatively complex, resulting in high costs and difficulties in disassembly and assembly. Utility Model Content

[0005] Based on this, a water pump capable of filtering and discharging slag is provided to solve the problem that the filter structure of existing water pumps with non-disassembly slag discharge is too complex.

[0006] On the one hand, this utility model provides a water pump capable of filtering and discharging slag, the water pump comprising:

[0007] Water inlet channel, used for water intake of the water pump;

[0008] The filter element is connected to the water inlet channel. The filter element has a mesh structure and is used to separate impurities in the water inlet.

[0009] The impurity storage section is located on the water inlet side of the filter element and is connected to the water inlet channel. The impurity storage section is used to hold impurities.

[0010] The slag discharge channel is connected to the miscellaneous waste storage section.

[0011] in,

[0012] When the water pump is in normal use, the slag discharge channel is closed;

[0013] When the water pump discharges slag, the slag discharge channel is open, and water is introduced along the water inlet channel to flush the impurities in the impurity storage section into the slag discharge channel and discharge them.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] In one implementation, the filter element is a ring-shaped hollow mesh structure, with the water outlet side of the filter element located in the middle of the filter element.

[0016] In one implementation, the impurity storage section surrounds the outer periphery of the filter element.

[0017] In one implementation, the upper part of the waste storage section is connected to the water inlet channel, and the lower part of the waste storage section is connected to the slag discharge channel.

[0018] In one implementation, the water inlet channel is L-shaped, with the upper part of the water inlet channel arranged horizontally and the lower part of the water inlet channel arranged vertically and connected to the miscellaneous storage section.

[0019] The slag discharge channel is L-shaped, with the upper part of the slag discharge channel set vertically and connected to the miscellaneous storage section, and the lower part of the slag discharge channel set horizontally.

[0020] In one implementation, the diameter of the vertical section of the slag discharge channel is larger than the diameter of the horizontal section.

[0021] In one implementation, the filter includes:

[0022] The filter section is located in the middle of the filter element and is mesh-like.

[0023] The connecting parts are located at both ends of the filter element and are used to connect to the inner wall of the water pump so that all water entering along the water inlet channel must be filtered by the filter element before entering the inner cavity of the water pump.

[0024] In one implementation, the connection is a deformable sealing abutment structure or a threaded structure.

[0025] In one implementation, the water pump also includes:

[0026] The filter element can be detachably placed into the disassembly channel;

[0027] End cap: One end of the disassembly channel is connected to and closed by the end cap, while the other end of the disassembly channel is used to accommodate the filter element.

[0028] In one implementation, the water pump also includes:

[0029] The flushing switch is located on the outer wall of the water pump housing. The flushing switch is used to control the opening and closing of the water pump's slag discharge operation.

[0030] Water outlet channel, used for water pump discharge;

[0031] Check valve, the check valve is connected to the water outlet channel.

[0032] The beneficial effects of this utility model are as follows: By setting a mesh filter element to filter the water entering the inlet channel, impurities can be blocked in the impurity storage section to prevent highly destructive particulate impurities from entering the water pump; since the impurity storage section is connected to both the slag discharge channel and the inlet channel, during slag discharge, the inlet water will enter through the inlet channel and rinse the impurity storage section and the filter element, and then flush the impurities into the slag discharge channel and discharge them; compared with the existing technology, which cannot clean or discharge the filter screen in a timely manner, this application can perform slag discharge and rinsing at any time without disassembling the filter screen structure. Timely rinsing avoids the problem of excessive impurities clogging the filter screen, and the slag discharge process does not require disassembly, cleaning, or replacement of the filter element; compared with the complex impurity discharge filter screen structure of the prior art, the structure of this application is simple, effectively reducing the cost of the water pump and facilitating the disassembly, assembly, and maintenance of the water pump; it effectively reduces the time spent on slag discharge and the workload of maintenance, thereby reducing the impact of slag discharge on production efficiency.

[0044] A water pump capable of filtering and discharging sludge, see [link to relevant documentation]. Figure 1 and Figure 2 The water pump includes an inlet channel 1, a filter element 2, a storage compartment 3, and a sludge discharge channel 4. The inlet channel 1 is used for water intake. The filter element 2 is connected to the inlet channel 1 and has a mesh structure for separating impurities from the incoming water. The storage compartment 3 is located on the water intake side of the filter element 2 and is connected to the inlet channel 1. The storage compartment 3 is used to hold impurities. The sludge discharge channel 4 is connected to the storage compartment 3. In this way, when water is intake, it is filtered through the filter element 2, which blocks particulate or large impurities in the water, causing the impurities to accumulate in the storage compartment 3. Since the impurities need to be discharged through the sludge discharge channel 4, the sludge discharge channel 4 is connected to the storage compartment 3, so that the impurities in the storage compartment 3 can enter the sludge discharge channel 4 during sludge discharge, facilitating the discharge of impurities.

[0045] Figure 2 In the diagram, A represents an impurity, indicating an embodiment where impurity aggregation may occur.

[0046] When the water pump is in normal use, the slag discharge channel 4 is in the closed state. In this way, when the water pump is running normally, the water enters the inner cavity of the water pump along the water inlet channel 1. At this time, the slag discharge channel 4 is closed to prevent the water from flowing out along the slag discharge channel 4, thereby ensuring the water intake inside the water pump.

[0047] When the water pump discharges slag, the slag discharge channel 4 is in the open state, and water is introduced through the water inlet channel 1 to flush the impurities in the impurity storage section 3 into the slag discharge channel 4 and discharge them. Thus, when slag is discharged, the slag discharge channel 4 is opened accordingly, and water flows out through the slag discharge channel 4 to flush the impurities in the impurity storage section 3, so that the impurities are flushed into the slag discharge channel 4 and flow out. The direction of water flow during slag discharge is water inlet channel 1, impurity storage section 3, and slag discharge channel 4.

[0048] This solution filters the water entering the inlet channel 1 using a mesh filter element 2, thereby blocking impurities in the impurity storage section 3 to prevent highly destructive particulate impurities from entering the water pump. Since the impurity storage section 3 is connected to both the slag discharge channel 4 and the inlet channel 1, during slag discharge, water enters through the inlet channel 1 and washes the impurity storage section 3 and the filter element 2, then flushes the impurities into the slag discharge channel 4 and discharges them. Compared to existing technologies that cannot clean or discharge the filter screen in a timely manner, this application allows for slag discharge and washing at any time without disassembling the filter screen structure. Timely washing prevents excessive impurities from clogging the filter screen at the filter element 2, and the slag discharge process does not require disassembly, cleaning, or replacement of the filter element 2. Compared to the complex impurity discharge filter structure in existing technologies, this application has a simple structure, effectively reducing the cost of the water pump and facilitating its disassembly, assembly, and maintenance. It effectively reduces the time spent on slag discharge and the workload of maintenance, thereby reducing the impact of slag discharge on production efficiency.

[0049] In other embodiments, see Figure 1 and Figure 2 There are no specific limitations on the position of the filter element 2, as long as the filter element 2 can filter the water entering the water in the water inlet channel 1. The filter element 2 can be located at the end of the water inlet channel 1 or in the middle of the water inlet channel 1.

[0050] In other embodiments, see Figure 1 and Figure 2 Since the filter element 2 uses a mesh structure for filtration, the impurities separated by the filter element 2 in this application need to be tangible, such as granular or flake-shaped impurities, and the size of the impurities needs to be larger than the filter screen of the filter element 2.

[0051] In other embodiments, see Figure 1 and Figure 2When performing the slag discharge operation, the water flow inside the water pump should ideally remain still. This way, when water is introduced into the water inlet channel 1, only the slag discharge channel 4 will discharge water, and the water pump's internal cavity will not be filled with water. This ensures the water output of the slag discharge channel 4, which is necessary to clean the impurities in the impurity storage section 3 and also to flush down the impurities hanging on the mesh structure of the filter element 2.

[0052] In some embodiments, see Figure 2 and Figure 3 The filter element 2 has a ring-shaped hollow mesh structure, with the water outlet side of the filter element 2 located in the middle. In this way, when the filter element 2 is ring-shaped, the entire outer periphery of the ring can be used for water filtration, thereby improving the filtration efficiency; in addition, when the filter element 2 is ring-shaped, the outer periphery of the ring can be a storage part 3, thereby increasing the storage capacity for impurities.

[0053] In other embodiments, the filter element 2 is not necessarily annular; it can also be a sheet-like structure that blocks the water flow direction in the inlet channel 1. For example, when the inlet channel 1 is a circular pipe, the corresponding filter element 2 is a circular filter screen. Compared to the sheet-like filter element 2 structure, the annular filter element 2 has a larger filtration area, increasing the area through which water can pass and ensuring the filtration speed. In addition, when the mesh of the filter element 2 is partially blocked by impurities, the annular filter element 2 still has a sufficient mesh filtration area, thereby reducing the frequency of rinsing impurities, reducing the occurrence of filter element 2 blockage, and improving the service life of the filter element 2.

[0054] In some embodiments, see Figure 2 and Figure 3 The impurity storage section 3 surrounds the outer periphery of the filter element 2. In this way, the annular impurity storage section 3 has a larger volume and can store a larger amount of impurities, thereby effectively reducing the frequency of impurity removal and rinsing, which helps to improve production efficiency.

[0055] In some embodiments, see Figure 2 and Figure 3 The upper part of the impurity storage section 3 is connected to the water inlet channel 1, and the lower part of the impurity storage section 3 is connected to the slag discharge channel 4. In this way, the water inlet channel 1, the impurity storage section 3, and the slag discharge channel 4 are connected in sequence along the vertical direction. The water inlet channel 1 is located at the upper part of the impurity storage section 3, and the slag discharge channel 4 is located at the lower part of the impurity storage section 3. When the water pump is working normally, it is convenient for particulate impurities to fall into the impurity storage section 3 near the slag discharge channel 4. When slag is discharged and flushed, it is also convenient for impurities to be flushed out along the lower slag discharge channel 4 in the slag discharge direction from top to bottom.

[0056] In some embodiments, see Figure 1 and Figure 2The water inlet channel 1 is L-shaped, with its upper part arranged horizontally and its lower part arranged vertically and connected to the impurity storage section 3. This L-shape ensures that the contact point between the water inlet channel 1 and the filter element 2 is vertical. Furthermore, because the water flows vertically downwards to the filter element 2, it facilitates flushing the impurities filtered by the filter element 2 into the lower part of the impurity storage section 3 for subsequent removal.

[0057] See Figure 2 and Figure 3 The slag discharge channel 4 is L-shaped. The upper part of the slag discharge channel 4 is vertically arranged and connected to the impurity storage section 3, while the lower part of the slag discharge channel 4 is horizontally arranged. In this way, by setting the slag discharge channel 4 in an L-shape and making the end of the slag discharge channel 4 connected to the impurity storage section 3 vertically arranged, it is convenient for impurities located in the impurity storage section 3 to be flushed into the slag discharge channel 4 with the incoming water during slag discharge, thereby facilitating the discharge of impurities.

[0058] In some embodiments, see Figure 3 The diameter of the vertical section of the slag discharge channel 4 is larger than the diameter of the horizontal section. Since the vertical section of the slag discharge channel 4 is directly connected to the impurity storage section 3, increasing the diameter of the vertical section facilitates the entry of impurities from the impurity storage section 3 into the slag discharge channel 4, thereby improving slag discharge efficiency.

[0059] In some embodiments, see Figure 2 and Figure 3 The filter element 2 includes a filter section 2-1 and a connecting section 2-2. The filter section 2-1 is located in the middle of the filter element 2 and is mesh-like. The connecting section 2-2 is located at both ends of the filter element 2 and is used to connect to the inner wall of the water pump, so that all incoming water entering along the water inlet channel 1 must be filtered by the filter element 2 before entering the inner cavity of the water pump. In this way, the filter element 2 as a whole is used to filter the incoming water. Since the filter element 2 is placed inside the water pump, the middle part of the filter element 2 is configured as a mesh structure to filter the incoming water, and the two ends of the filter element 2 are configured as connecting structures to facilitate fixing the filter element 2 to the water pump. By adjusting the connecting section 2-2 and the corresponding mating structure, the connecting section 2-2 can seal the connection position between the water inlet channel 1 and the inner cavity of the water pump, so that all incoming water must be filtered by the filter section 2-1 before entering the inner cavity of the water pump, thereby providing better protection for the water pump.

[0060] In some embodiments, see Figure 2 and Figure 3The connecting part 2-2 is a deformable sealing abutment structure or a threaded structure. In this way, the connecting part 2-2 is connected to the inner hole structure of the water pump. The specific connection method can be a threaded connection, or the connecting part 2-2 is a deformable structure, which forms an effective and stable connection and seal through the extrusion deformation of the connecting part 2-2.

[0061] In some embodiments, see Figure 2 and Figure 3 The water pump also includes a disassembly channel 5 and an end cap 6. The filter element 2 is detachably placed into the disassembly channel 5. One end of the disassembly channel 5 is connected to and closed by the end cap 6, while the other end of the disassembly channel 5 is used to accommodate the filter element 2. In this way, the water pump is equipped with a disassembly channel 5 and a matching end cap 6, thereby creating an openable accommodating space at the disassembly channel 5. Placing the filter element 2 into the disassembly channel 5 facilitates the disassembly, cleaning, and replacement of the filter element 2, and also facilitates maintenance when the water inlet is blocked.

[0062] Specifically, the connection structure between the end cap 6 and the disassembly channel 5 can be a threaded connection or a snap-fit ​​connection; after installation, the end cap 6 can abut against the axial end of the filter element 2, thereby facilitating the tightening of the filter element 2 through the end cap 6 and preventing the filter element 2 from loosening.

[0063] In some embodiments, see Figure 1 and Figure 4 The water pump also includes a flushing switch 7, a water outlet channel 8, and a check valve 9. The flushing switch 7 is located on the outer wall of the water pump housing and is used to control the opening and closing of the water pump's slag discharge operation. The water outlet channel 8 is used for water discharge from the water pump. The check valve 9 is connected to the water outlet channel 8. In this way, the flushing switch 7 is set to control the opening and closing of the slag discharge flushing program. When the water pump is in normal use, the incoming water passes through the inlet channel 1, the filter element 2, and the outlet channel 8 in sequence.

[0064] When discharging slag, the corresponding slag discharge channel 4 is opened. At this time, the inner cavity of the corresponding water pump should ideally be in a state where no water enters. The check valve 9 is also opened, and the water pump is in a state of stopping operation. The water in the inner cavity of the water pump remains still under negative pressure. At this time, the water entering along the water inlet channel 1 will only be discharged along the slag discharge channel 4, thereby ensuring that there is enough water flow to rinse the filter element 2 and the impurity storage section 3 during the slag discharge process, so as to improve the efficiency of impurity removal during the slag discharge rinsing process.

[0065] In other embodiments, the filterable slag-discharging water pump of this application can be equipped with a corresponding controller and panel. The panel can be used to display and remind users of the slag discharge cycle. It can also be linked to an APP for operation or slag discharge cycle query. The APP can also remind users to regularly discharge and flush slag.

[0066] The integrated installation structure of this application also saves the overall space occupied by the water pump, thereby increasing the application range of the water pump; the filtration and slag removal structure set in this application can effectively avoid power loss and failure of the water pump caused by foreign objects.

[0067] This application can be applied to booster pumps, using pressure sensor 10 for start / stop control and frequency conversion regulation. For example, in start / stop control (on / off mode), pressure sensor 10 sets a lower pressure limit (start value) and an upper pressure limit (stop value). When the pipeline pressure is below the lower limit, the sensor triggers a signal → the controller starts the pump; when the pressure reaches the upper limit, a stop signal is triggered → the pump stops.
