[0003] The current subway sewage treatment process involves the following steps: sewage from the restrooms flows into a collection tank. Once the tank reaches a set water level, a sewage pump starts, lifting the sewage and discharging it into the municipal sewer network. However, this existing technology has the following drawbacks:

[0004] a. When plastic bags, rags, sanitary napkins, keys, or mobile phones enter the pipes, it can cause minor blockages or, in severe cases, damage to the pump body, leading to malfunctions in the entire equipment and affecting the normal operation of the system.

[0005] b. After prolonged use, suspended solids in the wastewater adhere to the side walls of the tank, requiring regular manual cleaning for normal operation, which inevitably increases maintenance costs. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a crushing bar type sewage lifting device, which solves the problems that when plastic bags, rags, sanitary napkins, keys, and mobile phones enter the pipes, they can cause minor blockages or even damage to the pump body, leading to equipment malfunctions and affecting the normal operation of the system. Furthermore, after prolonged use, suspended solids in the sewage adhere to the side walls of the tank, requiring only periodic manual cleaning.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a crushing and bar-type sewage lifting device, comprising a water tank and a water pump installed on one side thereof, a crusher being fixedly connected through the left side of the top of the water tank, and bar screens being fixedly connected inside the water tank and on both sides of the crusher, wherein the mesh size of the left bar screen is larger than that of the right bar screen, a water suction pipe being fixedly connected through the bottom of the right side of the water tank, and the right end of the water suction pipe being connected to the water inlet of the water pump through a valve, the water outlet of the water pump being connected to a water outlet pipe, and a backwash pipe being connected to the surface of the water outlet pipe, and a water spraying square pipe being fixedly connected to the top of the left side of both bar screens, wherein the bottom end of the water spraying square pipe has an oblique water spray hole that tilts to the right, and the left end of the backwash pipe penetrating the right wall of the water tank and the bar screen being connected to both sets of water spraying square pipes.

[0008] Preferably, a base is fixedly connected to the bottom of the water tank, and a control cabinet is fixedly connected to the upper right corner of the front of the water tank.

[0009] Preferably, the water pump is fixedly connected to the right side of the top of the base by a bracket, and two sets of water pump, water suction pipe, water discharge pipe and backwash pipe are respectively provided.

[0010] Preferably, the inner cavity of the water tank located to the left of the left side of the left side of the grating plate is designated as area A, and the inner cavity of the water tank located to the right of the right side of the grating plate is designated as area B.

[0011] Preferably, the top of the water tank, and the top of areas A and B, are respectively fixedly connected to a left top cover and a right top cover by bolts.

[0012] Preferably, an exhaust pipe is fixedly connected to the right rear corner of the top of the water tank, and a liquid level sensor is fixedly connected through the right front corner of the top of the water tank, with the bottom end of the liquid level sensor extending to the bottom of the inner cavity of the water tank.

[0015] Beneficial effects

[0016] This invention provides a wastewater lifting device using a crushed bar screen. Compared with the prior art, it has the following advantages:

[0017] (1) The crushing bar type sewage lifting device can crush large particles of impurities in area A into small pieces and discharge them into area B by setting a crusher in conjunction with the bar plate. Then, the pieces are pumped away by the water pump, which can avoid the blockage of pipes or damage to the water pump by debris, and reduce the chance of the sewage system being paralyzed. At the same time, the backwash pipe in conjunction with the water spray square pipe can spray some of the discharged sewage onto the surface of the bar plate, which can wash off the impurities attached to its surface, thereby keeping the water flow from area A to area B unobstructed and ensuring drainage efficiency.

[0018] (2) The crushed bar type sewage lifting device monitors the water level in zone B by setting a liquid level sensor. When the liquid level rises to a certain height, the water pump can be automatically started to lift the sewage. When the water level in zone B drops to a certain height, the water pump can be automatically shut off to store water, ensuring the maximum utilization rate of the water pump. The automated operation is more energy-efficient.

[0019] (3) The crushing grid type sewage lifting device can collect large pieces of debris that cannot pass through the grid plate for crushing by setting a collection basket below the inlet pipe. The collection basket is set on the side, and the debris falling in the middle is guided to both sides by the triangular arch plate, making it convenient to take out the collection basket and clean the debris. It is easy to use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-4 This invention provides a technical solution: a crushing and bar-type sewage lifting device, comprising a water tank 1 and a water pump 2 installed on one side, a crusher 3 is fixedly connected through the left side of the top of the water tank 1, and bar screens 4 are fixedly connected inside the water tank 1 and on both sides of the crusher 3, with the mesh size of the left bar screen 4 being larger than that of the right bar screen 4. A water suction pipe 5 is fixedly connected through the bottom of the right side of the water tank 1, and the right end of the water suction pipe 5 is connected to the water inlet of the water pump 2 through a valve. The water outlet of the water pump 2 is connected to a water outlet pipe 6, and a backwash pipe 7 is connected to the surface of the water outlet pipe 6. A water spray square pipe 8 is fixedly connected to the top of the left side of each of the two bar screens 4, and the bottom end of the water spray square pipe 8 has a slanted water spray hole 9 with the lower end tilted to the right. The left end of the backwash pipe 7 penetrates the right wall of the water tank 1 and the bar screen 4 and is connected to both sets of water spray square pipes 8. By setting up a crusher 3 in conjunction with a grating plate 4, large particles of impurities in area A can be crushed into small pieces and discharged into area B, where they are then pumped away by water pump 2. This avoids debris clogging the pipes or damaging the water pump 2, reducing the chance of the sewage system malfunctioning. At the same time, by using a backwash pipe 7 in conjunction with a water spray square pipe 8, some of the discharged sewage can be sprayed onto the surface of the grating plate 4, which can wash off the impurities attached to its surface, thereby maintaining smooth water flow from area A to area B and ensuring drainage efficiency.

[0027] The bottom of the water tank 1 is fixedly connected to the base 10, and the water pump 2 is fixedly connected to the right side of the top of the base 10 through the bracket 12. The water pump 2, the water suction pipe 5, the water outlet pipe 6 and the backwash pipe 7 are each provided in two sets.

[0028] The inner cavity of water tank 1, located to the left of the left side of the left side of the grid plate 4, is designated as area A. The inner cavity of water tank 1, located to the right of the right side of the grid plate 4, is designated as area B. The top of water tank 1, located at the top of areas A and B, is respectively fixedly connected to the left top cover 13 and the right top cover 14 by bolts.

[0029] An exhaust pipe 15 is fixedly connected to the rear right corner of the top of water tank 1, and a liquid level sensor 16 is fixedly connected through the front right corner of the top of water tank 1, with the bottom end of the liquid level sensor 16 extending to the bottom of the inner cavity of water tank 1. A control cabinet 11 is fixedly connected to the upper right corner of the front of water tank 1, and the control cabinet 11 is electrically connected to water pump 2 and liquid level sensor 16 via wires. By setting the liquid level sensor 16 to monitor the water level in zone B, water pump 2 can be automatically started to lift sewage when the liquid level rises to a certain height, and water pump 2 can be automatically shut off to store water when the water level in zone B drops to a certain height, ensuring the maximum utilization rate of water pump 2 and making the automated operation more energy-efficient.

[0030] A water inlet pipe 17 is fixedly connected to the top left side of water tank 1. Between the left side of the inner wall of water tank 1 and the left side grid plate 4, and directly below the water inlet pipe 17, a triangular arch plate 18A is fixedly connected to the bottom of area A, with multiple sets of supporting vertical plates 19 fixedly connected in parallel. Collection baskets 20 are placed on the top of the supporting vertical plates 19 and below the front and rear sides of the triangular arch plate 18. By setting the collection baskets 20 below the water inlet pipe 17, large pieces of debris that cannot pass through the grid plate 4 and be broken can be collected. Furthermore, by placing the collection baskets 20 on the side and using the triangular arch plates 18 to guide the debris falling from the center to the sides, it is easy to remove the collection baskets 20 for cleaning, making it convenient to use.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] Working principle:

[0033] a. Domestic sewage enters water tank 1 through inlet pipe 17 and is dispersed into collection baskets 20 on both sides by triangular arch plate 18. Large debris is collected in collection baskets 20. Small particles in sewage pass directly from zone A through grid 4 into zone B. Large particles are intercepted in zone A by grid 4 and are crushed into small particles by crusher 3 before entering zone B of water tank 1.

[0034] b. When the sewage reaches the set maximum water level of water tank 1, the level sensor 16 transmits the level signal to the control cabinet 11.

[0035] c. Control cabinet 1 sends a start command to water pump 2, water pump 2 starts, and lifts sewage to the above-ground municipal sewage pipe network through water outlet pipe 6.

[0036] d. While the sewage is being lifted, a portion of the sewage in the outlet pipe 6 flows back into the spray pipe 8 through the backwash pipe 7, and is sprayed downwards onto the grid 4 through the inclined spray holes 9, spraying and rinsing the surface of the grid 4 to remove suspended solids attached to the grid 4 and keep the water flow from area A to area B unobstructed.

[0037] e. As the sewage in water tank 1 continues to rise, the sewage level gradually drops. When the sewage level in water tank 1 drops to the set minimum water level, the level sensor 16 transmits the level signal to the control cabinet 11.

[0038] f. Control cabinet 11 sends a stop command to water pump 2, water pump 2 stops working, and water tank 1 continues to accumulate sewage through inlet pipe 17. This completes one working cycle of the equipment.

[0039] g. Periodically open the left top cover 13, remove the collection basket 20, clean out the large debris inside, and then put it back.
