Description

Technical Field

[0001] The invention relates to the technical field of submersible pumps, in particular to a high-efficiency cutting submersible sewage pump driven by dual power. Background Art

[0002] In the field of submersible pump technology, submersible sewage pumps are key equipment for treating sewage containing solid impurities and fiber-like substances, and are widely used in municipal sewage treatment, industrial wastewater discharge, construction foundation pit drainage, etc. In the existing technology, conventional cutting submersible sewage pumps mostly adopt a single-power drive mode, using a single motor to drive the pumping impeller and cutting assembly at the same time, or are only equipped with a single type of cutting blade. When faced with complex sewage mixed with high-concentration entangled impurities (such as long fibers, plastic bags) and large-particle solids, problems such as insufficient crushing efficiency and pump blockage are prone to occur, resulting in reduced equipment operation stability and increased maintenance frequency.

[0003] In the traditional single-power drive mode of submersible sewage pumps, the power coordination between the cutting component and the pumping function is insufficient, and a single type of blade is difficult to efficiently crush mixed impurities, resulting in the equipment being easily blocked and having low flow efficiency in complex sewage discharge environments, and being unable to meet the drainage needs of high loads and high impurity concentrations. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a dual-power-driven high-efficiency cutting submersible sewage pump, which solves the problems that traditional submersible sewage pumps are easily blocked in complex sewage discharge environments, have low flow efficiency, and cannot meet the drainage needs of high loads and high impurity concentrations.

[0006] Preferably, the driving component 1 includes a submersible motor 1, the outer wall of the submersible motor 1 is fixedly connected to the left outer wall of the outer shell, the output end of the submersible motor 1 is connected to a connecting column 1, the outer wall of the connecting column 1 is fixedly connected to a fan blade, the outer wall of the fan blade is rotatably connected to the inside of the outer shell, and the outer wall of the connecting column 1 is fixedly connected to a fixing column.

[0007] Preferably, the cutting assembly comprises an inner wall of a mounting shell rotatably connected to the interior of a fixed column, an outer wall of the mounting shell is fixedly connected to a blade 2, and an outer wall of the blade 2 is rotatably connected to the interior of the outer shell.

[0008] Preferably, the transmission assembly includes a bevel gear 1, the outer wall of which is fixedly connected to the outer wall of a connecting column 1, the inner wall of which is fixedly connected to a mounting column 1, the inner wall of which is fixedly connected to a mounting column 2, one side tooth end of the bevel gear 1 is meshingly connected to a bevel gear 2, the other side tooth end of the bevel gear 1 is meshingly connected to a bevel gear 3, the tooth end of the bevel gear 3 is meshingly connected to a bevel gear 4, the tooth end of the bevel gear 4 is meshingly connected to the tooth end of the bevel gear 2, and the outer wall of the bevel gear 4 is fixedly connected to a mounting shell.

[0009] Preferably, the driving component 2 includes a submersible motor 2, the outer wall of the submersible motor 2 is fixedly connected to the right outer wall of the outer shell, the output end of the submersible motor 2 is connected to a connecting column 2, and the outer wall of the connecting column 2 is fixedly connected to a blade 1.

[0010] Preferably, the cutting edges of blade one and blade two are arranged in opposite directions, blade one is a spiral blade, and blade two is a serrated blade.

[0011] Preferably, the control center includes a microprocessor and a power regulation module, and the microprocessor is connected to an external device via a wireless communication module.

[0012] Preferably, the inner wall of the shell is coated with a corrosion-resistant coating.

[0013] Preferably, glass is provided inside the fixed shell.

[0014] Preferably, the outer wall of the mounting column one is fixedly connected to the outer wall of the connecting column one, and the inner walls of the bevel gear two and the bevel gear three are both rotatably connected to the outer wall of the mounting column two.

[0015] Working principle: When the dual-power-driven high-efficiency cutting submersible sewage pump is working, the submersible motor 1 of the driving component 1 and the submersible motor 2 of the driving component 2 operate synchronously or independently. The submersible motor 1 drives the fan blades through the connecting column 1 to realize the pumping function of sucking liquid from the liquid inlet and transporting it to the liquid outlet. At the same time, the connecting column 1 drives the bevel gear 1 of the transmission component to rotate, and the gear set composed of bevel gears 2, 3, and 4 transmits power to the mounting shell of the cutting component, driving the serrated blade 2 to rotate at high speed. The submersible motor 2 directly drives the spiral blade 1 with the opposite cutting edge direction to the blade 2 to rotate through the connecting column 2, and the two form an efficient crushing structure that cuts in opposite directions. The spiral blade 1 uses the spiral propulsion force to introduce the entangled impurities in the sewage into the cutting area and preliminarily tear the large particles of impurities. The serrated blade 2 finely cuts the impurities through the high-frequency serrated edge.

[0016] The microprocessor in the control center receives external instructions or real-time monitoring data through the wireless communication module, and dynamically adjusts the output power of the two motors in combination with the power regulation module. It increases the speed to enhance the cutting force when there are high concentrations of impurities or oversized particles, and reduces the power to save energy when the load is low.

[0017] After the sewage is sucked in through the liquid inlet, it is first crushed by the cutting component and then pushed to the liquid outlet by the fan blades under pressure. The corrosion-resistant coating on the inner wall of the outer shell resists corrosion from sewage. The glass inside the fixed shell is convenient for observing the status of the control center or the operation of the internal fluid. The dual power system combines gear transmission with direct drive to achieve efficient coordination of cutting and pumping functions. Combined with the intelligent control module, the equipment has both strong crushing ability and energy-saving characteristics in complex sewage discharge environments, thereby improving applicability and reliability.

[0018] The present invention provides a high-efficiency cutting submersible sewage pump driven by dual power. It has the following beneficial effects: 1. The present invention drives the fan blades, blade one and cutting assembly respectively by submersible motor one and submersible motor two, thereby forming a "pumping and crushing" dual-function synergy. The cutting edges of spiral blade one and serrated blade two are in opposite directions, which significantly improves the crushing efficiency of complex impurities and avoids clogging of the pump body.

[0019] 2. Driven by submersible motor 1, the fan blades of the present invention are responsible for sucking sewage from the liquid inlet and transporting it to the liquid outlet. Since the impurities have been effectively crushed by blades 1 and 2, their size becomes smaller and their fluidity is enhanced. At the same time, blade 1 can assist sewage to flow out of the liquid outlet faster while rotating, thereby improving pumping efficiency and increasing the amount of sewage transported per unit time.

[0020] 3. The inner wall of the shell of the present invention is coated with a corrosion-resistant coating to form a dense protective layer, which can effectively resist the erosion of acids, alkalis, chloride ions and microorganisms in sewage, extend the service life of the equipment in harsh environments such as chemical wastewater and municipal sewage, and extend the maintenance cycle compared to conventional products.

[0021] 4. The control center of the present invention integrates a microprocessor, a power regulation module and a wireless communication module to realize dynamic power regulation and remote operation and maintenance, significantly reducing the cost of manual inspections and improving equipment operation and maintenance efficiency.

[0024] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Please refer to the attached Figure 1 -Attached Figure 3 An embodiment of the present invention provides a dual-power-driven high-efficiency cutting submersible sewage pump, including a shell 1, an upper inner wall of the shell 1 is fixedly connected with a liquid inlet 2, a lower inner wall of the shell 1 is fixedly connected with a liquid outlet 3, a left outer wall of the shell 1 is fixedly connected with a driving component 1 4, a right outer wall of the shell 1 is fixedly connected with a driving component 2 5, an upper outer wall of the shell 1 is fixedly connected with a fixed shell 6, the interior of the fixed shell 6 is fixedly connected with a control center 7, a right outer wall of the driving component 1 4 is rotatably provided with a cutting component 8, a transmission component 9 is arranged inside the driving component 1 4, and the outer wall of the transmission component 9 is fixedly connected to the inner wall of the cutting component 8.

[0026] Specifically, when the dual-power-driven high-efficiency cutting submersible sewage pump is working, the driving component 4 is used to realize the pumping function of sucking sewage from the liquid inlet 2 and transporting it to the liquid outlet 3; at the same time, it drives the transmission component 9 to rotate, and the rotation of the transmission component 9 will drive the cutting component 8 to rotate in the opposite direction, forming a crushing structure that cuts in opposite directions. The two cooperate to efficiently crush various types of solid waste, avoid blockage and improve flow capacity.

[0027] The microprocessor of the control center 7 receives external device instructions through the wireless communication module and adjusts the output power of the drive component 1 4 and the drive component 2 5 .

[0028] After the sewage is sucked in through the liquid inlet 2, the impurities are first crushed by the cutting component 8 and the driving component 4, and then the impurities are pushed to the liquid outlet 3 for discharge through the fan blades 43. When the flow rate at the liquid inlet 2 is too large, the driving component 4 is started to cut the sewage and accelerate the outflow of the sewage from the liquid outlet 3.

[0029] Please refer to the attached Figure 2 and attached Figure 4 The driving component 4 includes a submersible motor 41, the outer wall of the submersible motor 41 is fixedly connected to the left outer wall of the outer shell 1, the output end of the submersible motor 41 is connected to a connecting column 42, the outer wall of the connecting column 42 is fixedly connected to a fan blade 43, the outer wall of the fan blade 43 is rotatably connected to the inside of the outer shell 1, and the outer wall of the connecting column 42 is fixedly connected to a fixing column 44.

[0030] Specifically, the submersible motor 41 is started, and the rotation of the submersible motor 41 drives the connecting column 42 at the output end to rotate. The rotation of the connecting column 42 drives the fan blade 43 to rotate, thereby realizing the pumping function of sucking sewage from the liquid inlet 2 and transporting it to the liquid outlet 3. At the same time, the rotation of the connecting column 42 drives the cutting assembly 8 to rotate in the opposite direction.

[0031] Please refer to the attached Figure 4 -Attached Figure 6 The transmission assembly 9 includes a bevel gear 91, the outer wall of which is fixedly connected to the outer wall of the connecting column 42, the inner wall of the bevel gear 91 is fixedly connected to a mounting column 92, the inner wall of the mounting column 92 is fixedly connected to a mounting column 2 96, one side tooth end of the bevel gear 91 is meshingly connected to a bevel gear 2 93, the other side tooth end of the bevel gear 91 is meshingly connected to a bevel gear 3 94, the tooth end of the bevel gear 3 94 is meshingly connected to a bevel gear 4 95, the tooth end of the bevel gear 4 95 is meshingly connected to the tooth end of the bevel gear 2 93, and the outer wall of the bevel gear 4 95 is fixedly connected to a mounting shell 81; the outer wall of the mounting column 92 is fixedly connected to the outer wall of the connecting column 42, the inner walls of the bevel gears 2 93 and 3 94 are both rotatably connected to the outer wall of the mounting column 2 96; the cutting assembly 8 includes an inner wall of a mounting shell 81 rotatably connected to the inside of the fixed column 44, the outer wall of the mounting shell 81 is fixedly connected to a blade 2 82, and the outer wall of the blade 2 82 is rotatably connected to the inside of the outer shell 1.

[0032] Specifically, the bevel gear 1 91 is driven to rotate by the connecting column 1 42, and the rotation of the bevel gear 1 91 will drive the bevel gear 2 93 and the bevel gear 3 94 to rotate on the outer wall of the mounting column 2 96, and then drive the bevel gear 4 95 to rotate in the opposite direction. Finally, the bevel gear 4 95 will drive the mounting shell 81 to rotate on the outer wall of the fixed column 44. The fixed column 44 provides reliable support for the mounting shell 81, ensuring that the mounting shell 81 can rotate smoothly. As the mounting shell 81 rotates, the blade 2 82 fixedly connected to its outer wall also rotates inside the outer shell 1.

[0033] Please refer to the attached Figure 2 and attached Figure 7 The driving component 2 5 includes a submersible motor 2 51 , the outer wall of the submersible motor 2 51 is fixedly connected to the right outer wall of the housing 1 , the output end of the submersible motor 2 51 is connected to a connecting column 2 52 , and the outer wall of the connecting column 2 52 is fixedly connected to a blade 1 53 .

[0034] Specifically, the output end of the submersible motor 2 51 drives the connecting column 2 52 to rotate, thereby causing the blade 1 53 to rotate accordingly. When sewage enters the equipment, the spiral blade 1 53 cuts the entangled impurities such as long fibers and ribbons in the sewage and large solid particles. When the sewage flow is too large, the blade 1 53 can also drive the sewage to be discharged from the liquid outlet 3 at an accelerated speed.

[0035] Please refer to the attached Figure 1 -Attached Figure 3 The cutting edges of blade one 53 and blade two 82 are arranged in opposite directions, blade one 53 is a spiral blade, and blade two 82 is a serrated blade.

[0036] Specifically, during the rotation process, the spiral blade 53 can actively draw in the entangled impurities by utilizing its spiral propulsion force, thereby concentrating the impurities that may have been dispersed in the sewage, and preparing for subsequent cutting work. At the same time, the spiral structure can also perform preliminary tearing of large particles of solids during rotation, thereby reducing the size of the large particles of solids and reducing the difficulty of subsequent fine cutting.

[0037] The serrated blade has high-frequency cutting ability, which can finely cut the impurities that have been initially torn, and can break the impurities into smaller particles, avoiding the accumulation and blockage of impurities inside the pump body. Whether it is hard particles or soft fibers, the serrated blade 82 can effectively break them up to ensure the normal operation of the equipment.

[0038] Please refer to the attached Figure 3 The control center 7 includes a microprocessor and a power regulation module, and the microprocessor is connected to an external device through a wireless communication module; the inner wall of the outer shell 1 is coated with a corrosion-resistant coating; and the interior of the fixed shell 6 is provided with glass.

[0039] Specifically, the microprocessor collects equipment operation data in real time, such as motor speed, load current, cutting torque, etc. After analysis, it sends instructions to the power regulation module to adjust the output power of submersible motor 1 41 and submersible motor 2 51. The joint between the glass and the fixed shell 6 is sealed by welding process to ensure IP68 waterproof performance under diving conditions, while withstanding external impact to ensure the safety of internal electronic components.

[0040] The corrosion-resistant coating uses polytetrafluoroethylene PTFE, epoxy resin or ceramic-based corrosion-resistant materials to form a dense protective layer that can resist long-term erosion by acids and alkalis in sewage such as sulfates, chloride ions, oil stains and microorganisms.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
