[0002] Sewage pumps play a vital role in the drainage system of household appliances, wastewater treatment, and various occasions where solid particles or high-viscosity fluids need to be discharged. Although traditional diaphragm pumps and centrifugal pumps can effectively transport clean water, they often face blockage problems when dealing with liquids containing a large amount of solid impurities, fiber materials, or high-concentration suspended matter. This blockage will not only reduce the working efficiency of the pump, but in severe cases, it will even cause the pump to fail, increase maintenance costs, and affect the normal operation of the entire drainage system.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] The utility model provides an anti-clogging sewage pump, which realizes the control of the water inlet and outlet by integrating a diaphragm pump with a shell structure and a drive component, and effectively prevents the occurrence of clogging. The details are as follows:

[0034] like Figure 1-Figure 2 As shown, the anti-clogging sewage pump in this embodiment includes: a diaphragm pump 100, a housing 200, a plunger 300 and a driving assembly 400.

[0035] The housing 200 is installed on one side of the diaphragm pump 100 , and two groups of plungers 300 are installed inside the housing 200 for alternately blocking the water outlet and the water inlet of the diaphragm pump 100 ; the driving assembly 400 is installed on the housing 200 .

[0036] When the driving component 400 drives the piston 101 and the membrane of the diaphragm pump 100 to suck sewage into the pump cylinder through the water inlet, it simultaneously drives one group of plungers 300 to open the water inlet; when the driving component 400 drives the piston 101 and the membrane of the diaphragm pump 100 to discharge sewage out of the pump cylinder through the water outlet, it simultaneously drives another group of plungers 300 to open the water outlet.

[0037] Specifically, the structure of the diaphragm pump 100 is as follows: the diaphragm pump 100 is the core part of the pump, and is composed of a piston 101, a pump cylinder, and a membrane. The reciprocating motion of the piston 101 pushes the membrane, thereby changing the volume in the pump cylinder to achieve the suction and discharge of sewage. The motion control of the piston 101 ensures the stability and efficiency of the pumping process.

[0038] Design of housing 200: The housing 200 is installed next to the diaphragm pump 100, and its internal structure is carefully designed with two sets of plungers 300 built in. The housing 200 not only plays a role of protection and support, but more importantly, it dynamically manages the water inlet and outlet flow of the pump through its internal plunger system, and is a key structure to achieve the anti-clogging function.

[0039] Working principle of plunger 300: Each group of plungers 300 corresponds to the water inlet and outlet of diaphragm pump 100, and is connected to drive assembly 400 through a mechanical linkage mechanism. When diaphragm pump 100 is in the stage of sucking sewage, drive assembly 400 accurately controls a group of plungers 300 to open the water inlet, while ensuring that the plunger at the water outlet remains closed, which effectively prevents sewage from flowing back and reduces the possibility of impurities accumulating in the pump. On the contrary, in the sewage discharge stage, the originally closed plunger opens the water outlet and closes the water inlet at the same time, ensuring that the sewage is discharged smoothly without external interference.

[0040] Function of the drive assembly 400: The drive assembly 400 serves as the heart of the entire system and adjusts the action timing of the plunger 300.

[0041] Comprehensive technical effect: Through the above design, the anti-clogging sewage pump of this embodiment shows extremely high performance advantages in practical applications. It can not only effectively prevent the clogging problem caused by the accumulation of solid particles and fibrous materials in the pump, but also optimize the pumping efficiency and reduce energy consumption. In addition, the modularity and compactness of the design also facilitate maintenance and overhaul, reducing long-term operating costs. In summary, the sewage pump of this embodiment provides an efficient, reliable and easy-to-maintain solution for handling complex water quality environments.

[0042] like Figure 2-Figure 5 , Fig. 9 As shown, the driving assembly 400 comprises: a motor 401, a driving shaft 402, and a driving column 403. The motor 401 is mounted on the top of the housing 200 through a transmission, and the output end of the transmission is mounted with a driving shaft 402 extending into the interior of the housing 200; the driving column 403 is coaxially arranged with the driving shaft 402, and the plunger 300 and the piston 101 are both connected to the driving column 403.

[0043] Specifically, the motor 401: as the power source of the entire drive system, the motor 401 is installed on the top of the housing 200. The selected motor has the characteristics of high efficiency and energy saving, can adapt to different load requirements, and ensure continuous and stable power output.

[0044] Transmission: Located between the motor 401 and the drive shaft 402, its function is to adjust the motor speed according to the actual needs of the pumping task. The addition of the transmission allows the pump to process high-viscosity fluids or sewage with high solid content at low speeds, and to process clean or low-viscosity fluids at high speeds, thereby improving the adaptability and energy efficiency of the pump.

[0045] Drive shaft 402: connected to the motor through the output end of the transmission, extending downward through the top of the housing 200 to the inside. The drive shaft 402 is made of high-strength material to withstand the torsion and wear in long-term operation, ensuring the stability and reliability of power transmission.

[0046] Driving column 403: Coaxially arranged with driving shaft 402, driving column 403 is designed to drive the reciprocating motion of piston 101 and control the opening and closing of plunger 300, thereby achieving a perfect combination of pumping and anti-blocking functions.

[0047] Linkage mechanism: The plunger 300 and the piston 101 are both connected to the driving column 403. This linkage mechanism ensures that when the motor 401 is started, the rotation of the drive shaft 402 is converted by the driving column 403, thereby driving the piston 101 and the membrane to suck and discharge sewage, and at the same time controlling the plunger 300 to open and close the water inlet and outlet in time, thereby achieving effective control of sewage flow and prevention of blockage.

[0048] Furthermore, an eccentric wheel 404 is fixed on the top of the driving column 403, and a sleeve 405 is rotatably connected to the outside of the eccentric wheel 404, and one end of the piston 101 is connected to the outside of the sleeve 405. Two groups of semicircular shifting blocks 406 are fixed to the outside of the driving column 403, and the two groups of semicircular shifting blocks 406 are symmetrically arranged in an upper and lower structure, and each group of semicircular shifting blocks 406 corresponds to a group of plungers 300, and contacts the end of the plunger 300 during the rotation process.

[0049] The coordination between the eccentric wheel 404 and the shaft sleeve 405: An eccentric wheel 404 is fixedly installed on the top of the driving column 403. The outer edge of the eccentric wheel is designed to be a circular profile, and the center is not on the driving shaft 402. This design makes the eccentric wheel produce a reciprocating radial displacement when the driving column rotates. The outside of the eccentric wheel 404 is connected to the outside of the shaft sleeve 405 made of low-friction material. One end of the piston 101 is closely connected to the outside of the shaft sleeve 405. As the eccentric wheel rotates, the piston 101 performs precise reciprocating motion, driving the diaphragm pump 100 to complete the suction and discharge of sewage.

[0050] Innovative design of semicircular dial block 406: Two sets of semicircular dial blocks 406 are fixedly installed on the outside of the driving column 403, which are symmetrically distributed and arranged up and down. These dial blocks are designed to interact with the plunger 300 to achieve control of the water inlet and outlet. The position and shape of each set of semicircular dial blocks 406 are carefully calculated to ensure that when the driving column 403 rotates, the dial block can accurately contact the end of the corresponding plunger 300, pushing the plunger to move at the appropriate time point, thereby opening the water inlet during the suction stage of the pump and the water outlet during the discharge stage. At the same time, it is automatically closed in the non-working state to prevent water backflow or impurities from flowing back.

[0051] Working process: When the motor 401 is started and the speed is adjusted by the transmission, the driving shaft 402 drives the driving column 403 to rotate, and the rotation of the eccentric wheel 404 causes the sleeve 405 and the connected piston 101 to do reciprocating linear motion to achieve the suction and discharge of sewage. At the same time, as the driving column 403 rotates, the semicircular shift block 406 moves according to the predetermined trajectory, pushing the corresponding plunger 300 in time, accurately controlling the opening and closing of the water inlet and outlet, and effectively avoiding the blockage problem that the pump may encounter during operation.

[0052] like Figure 6-Figure 7 As shown, the plunger 300 includes a column head 301 , a column rod 302 , a spring 303 , a mounting block 304 and a roller 305 .

[0053] The column 302 is connected to one end of the column head 301 and is concentrically arranged. A spring 303 is sleeved on the outside of the column 302. The mounting block 304 is connected to the other end of the column head 301. The mounting block 304 is rectangular. The spring 303 is limited by the mounting block 304 and the column head 301 and will not be separated from the column 302. The roller 305 is installed on one side of the mounting block 304. A roller groove 306 is opened on one side of the mounting block 304. The roller 305 is rotatably installed inside the roller groove 306 through a pin shaft, and the roller 305 contacts the semicircular shifting block 406.

[0054] Structural design of the plunger assembly: The plunger 300 is precisely assembled from multiple parts, in which the column head 301 is designed to be the part that directly contacts the inner wall of the housing 200 and is responsible for physically closing or opening the water inlet and outlet. The column rod 302 serves as the main support of the plunger and is fixedly connected to one end of the column head 301 to form the driving shaft of the plunger. The outer sleeve of the column rod 302 is provided with a spring 303. This design is intended to provide the necessary elastic feedback force for the movement of the plunger, ensuring that it can quickly return to its original position after being acted upon by an external force, while buffering the impact during the movement and enhancing the stability and durability of the system.

[0055] Innovative integration of mounting block 304 and roller 305: Mounting block 304 is fixed to the other end of column head 301. Its rectangular structure not only provides support for the overall stability of the plunger, but also sets a roller groove 306 on one side. Roller 305 is installed in roller groove 306 through a pin, and can slide along the groove and rotate freely. This design enables the plunger to achieve smoother and low-friction operation through the smooth rolling contact of roller 305 under the push of semicircular shift block 406, reducing wear and extending service life.

[0056] In-depth analysis of the working principle: Under the action of the drive assembly 400, the semicircular shift block 406 moves with the rotation of the drive column 403. When the shift block contacts the roller 305, the force is transmitted through the rolling of the roller to push the plunger 300 to slide along the groove of the housing 200, thereby opening or closing the water inlet and outlet in a timely manner. In this process, the spring 303 not only plays a role in assisting the reset, but also absorbs the vibration of the plunger movement to keep the movement soft and precise. Since the contact area between the roller and the shift block is extremely small, the wear rate can be maintained at a low level even under frequent operation, ensuring the long-term and efficient operation of the system.

[0057] Technical effect deepening: Through the fine design of the above plunger assembly, the sewage pump of this embodiment not only improves the flexibility and response speed of the plunger action, but also significantly reduces the operating noise and maintenance cost. The contact mode between the roller and the dial block reduces direct friction, improves the smoothness and durability of the movement, and makes the entire sewage discharge process more efficient and reliable. In addition, the buffering effect of the spring ensures that the system can maintain good sealing performance under various working conditions, effectively prevents the invasion of external pollutants, and further consolidates the anti-clogging characteristics of the pump.

[0058] like Figure 8 As shown, the housing 200 includes: an upper shell 201 and a lower shell 202; the inner side wall of the upper shell 201 is provided with a slot body 203 for the plunger 300 to move; the lower end of the driving shaft 402 is rotatably mounted on the lower shell 202. The slot body 203 includes: a rectangular slot 204 and a circular through slot 205, the rectangular slot 204 matches the mounting block 304, and the mounting block 304 is movably connected in the rectangular slot 204; the circular through slot 205 is connected to the rectangular slot 204, and the column head 301, the column rod 302 and the spring 303 are all located inside the circular through slot 205. A spring ring is provided inside the circular through slot 205, and one end of the spring 303 is fixedly mounted on the spring ring.

[0059] Specifically, the shell structure is divided into: the shell 200 is divided into two parts, the upper shell 201 and the lower shell 202 are assembled together through a sealed and reliable connection method to form the main frame of the pump body. Such a split design is convenient for production and maintenance, while ensuring the strength and sealing of the shell.

[0060] The exquisite structure of the groove body 203: The inner side wall of the upper shell 201 is carefully designed with the groove body 203, which consists of a rectangular groove 204 and a circular through groove 205 connected thereto. The rectangular groove 204 matches the size of the mounting block 304, ensuring that the mounting block can slide smoothly in the groove without deviating from the track or generating unnecessary friction. The circular through groove 205 is designed to accommodate the column head 301, the column rod 302 and the spring 303. Such a layout not only saves space, but also provides a smooth channel for the linear motion of the plunger.

[0061] Stable installation of spring 303: A spring ring is specially arranged inside the circular through groove 205, one end of the spring 303 is fixed thereto, and the other end is connected to the column head 301 or directly connected to the column rod 302. This configuration allows the spring to provide the necessary resilience while maintaining a good positioning, avoiding deviation or relaxation under long-term operation, and ensuring the stability and reliability of the plunger movement.

[0062] Deepening of technical effects: Through the careful design of the above-mentioned shell and tank body, the sewage pump of this embodiment shows higher stability and longer service life in actual operation. The split shell structure is not only convenient for maintenance and replacement of parts, but also improves the stability of the overall structure. The combination of the rectangular groove of the tank body 203 and the circular through groove not only accurately guides the movement of the plunger, but also ensures the stable installation of the spring 303 through the design of the spring ring, further optimizing the movement control and sealing performance of the plunger.

[0063] In summary, the utility model can move synchronously with the operating rhythm of the diaphragm pump under the control of the driving component through the two groups of plungers arranged in the pump body.

[0064] When the diaphragm pump is absorbing water, the drive assembly ensures that one set of plungers opens the water inlet and closes the water outlet at the same time. This can effectively prevent external impurities from flowing back into the pump cylinder during the water absorption process, and is also conducive to sucking in more sewage. During the drainage stage, the other set of plungers opens the water outlet in a timely manner to ensure smooth discharge of sewage, and at the same time closes the water inlet to prevent backflow or intrusion of external substances caused by pressure fluctuations during the drainage process.

[0065] Through this design, the pump can always keep the inlet and outlet channels unobstructed during operation, greatly reducing the risk of clogging, especially when treating sewage containing a large amount of solid particles, long fiber materials or high concentration of suspended matter, showing excellent anti-clogging performance.

[0066] In addition, the design simplifies the complex mechanism added to the traditional sewage pump to prevent clogging, reduces maintenance requirements, and improves the reliability and economy of the overall system. Ultimately, the anti-clogging sewage pump not only improves the sewage treatment efficiency, but also extends the service life of the equipment, providing an efficient and reliable solution for sewage treatment under various complex working conditions.

[0067] In some other embodiments, in order to improve the driving accuracy and mechanical engagement stability, a semicircular gear ring 407 and a rack 408 are designed to replace the original contact method between the semicircular shift block 406 and the mounting block 304. Fig.10 As shown, this design further optimizes the control mechanism of the plunger 300, and the specific details are as follows:

[0068] Introduction of semicircular gear rings and racks: Two sets of symmetrically arranged semicircular gear rings 407 are fixedly installed on the outside of the driving column 403. They are symmetrically arranged up and down along the length of the driving column, and each set of gear rings controls the opening and closing of a set of plungers 300. These gear rings are designed with a specific tooth structure to form a precise mechanical meshing with the rack 408 at the end of the plunger.

[0069] Rack design at the end of the plunger: The end of each plunger 300 is designed with a rack 408 that matches the semicircular gear ring 407. The size and tooth shape of the rack are carefully calculated to ensure that when the drive column 403 rotates, the rack can be closely combined with the gear ring to achieve more precise opening and closing control. This design improves the synchronization and accuracy of the plunger action, and maintains good working performance even in rapid continuous operation or heavy load conditions.

[0070] Working principle and effect: When the driving assembly 400 drives the driving column 403 to rotate, the semicircular gear ring 407 rotates accordingly, and the toothed structure on it meshes with the rack 408 at the end of the plunger, pushing the plunger to move along the slot 203 to achieve precise control of the water inlet and outlet. Compared with the simple contact design, the cooperation between the gear ring and the rack provides a stronger driving force and higher control accuracy, reduces the efficiency loss and wear that may be caused by sliding friction, and enhances the reliability and durability of the system.

[0071] Improvement of technical effect: By adopting the precision meshing design of the semicircular gear ring 407 and the rack 408, the sewage pump of this embodiment has achieved significant improvement in control accuracy, response speed and long-term operation stability. This mechanism effectively reduces the uncertainty in the operation process, and can ensure the efficient and accurate action of the plunger even in a complex environment containing a large amount of solid particles or high-viscosity fluids, greatly reducing the risk of blockage and further consolidating the anti-blocking characteristics of the pump.

[0072] In some other embodiments, a hose may be installed in the water inlet and outlet of the diaphragm pump 100 for conveying water, and during the movement of the plunger 300, it may squeeze the hose to block the water inlet and outlet.

[0073] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
