[0001] The utility model relates to the technical field of sewage pumps, in particular to a base and a vertical sewage pump. Background Art

[0002] The sewage pump is one of the transportation equipment for sewage treatment. It can transport fluids containing a large amount of particles and fiber impurities, including domestic sewage, industrial wastewater, mud pond sewage, etc. It is widely used in municipal engineering, industrial production, production and breeding and other industries.

[0003] A vertical sewage pump is a specially designed pump that is primarily used to treat wastewater and drain water bodies, pumping liquids from low locations to high locations for efficient discharge and disposal. Unlike conventional water pumps, the main feature of a vertical sewage pump is its vertical design, where the motor and pumping sections are mounted on top of the pump, while the liquid handling portion of the pump is suspended in the liquid.

[0004] The sewage pump with a closed impeller not only has high operating efficiency, but also has a small axial thrust of the pump, which is conducive to long-term stable operation. However, the closed impeller sewage pump is prone to entanglement or blockage when conveying media containing long fibers and large particles, resulting in low flow and head of the sewage pump, limiting work efficiency, and in severe cases inducing shutdown failures. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a base and a vertical sewage pump, which solves the problem that the closed impeller sewage pump is prone to entanglement or blockage when conveying a medium containing long fibers and larger particles, resulting in low flow and head of the sewage pump, limiting work efficiency, and inducing shutdown failures in severe cases.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a base, used for a vertical sewage pump, comprises a support seat, at least two columns, a chamber, a rotating shaft, an impeller and a crushing assembly;

[0007] At least two of the columns are obliquely mounted on the support seat, the chamber is mounted on the upper end surfaces of at least two of the columns, the shaft is vertically rotatably connected to the inside of the chamber, and the impeller is arranged on the outside of the shaft;

[0008] The crushing assembly is arranged at the bottom of the chamber, and the crushing assembly includes a water inlet pipe, a top plate, at least two partition columns, a bottom plate, a transmission rod and at least two crushing plates;

[0009] The water inlet pipe is connected to the bottom of the chamber, the top plate is sleeved on the outside of the water inlet pipe, at least two of the partition columns are mounted on the lower surface of the top plate, the bottom plate is mounted on the bottom ends of at least two of the partition columns, the transmission rod is connected to the rotating shaft, and at least two of the crushing plates are installed in a ring-shaped arrangement on the outside of the transmission rod.

[0010] Furthermore, a support frame is installed on the top of the chamber, and a motor component with an output end drivingly connected to a rotating shaft is mounted on the support frame.

[0011] Furthermore, a drain pipe is connected to the outer peripheral surface of the chamber.

[0012] Furthermore, at least two of the partition columns are distributed in a circular array between the bottom plate and the top plate, and the partition columns are made of stainless steel.

[0013] Furthermore, the distance between two adjacent separation columns does not exceed one centimeter.

[0014] Furthermore, a gap of no more than 0.5 cm is retained between the crushing plate and the partition column.

[0015] Furthermore, the bottom end of the transmission rod is rotatably connected to the center of the upper surface of the bottom plate.

[0016] A vertical sewage pump comprises a base as described in any one of the above items.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 The base in this embodiment is used to install a vertical sewage pump and to provide support for the motor assembly 8 in the vertical sewage pump.

[0026] Specifically, it includes a support base 1, at least two columns 2, a chamber 3, a rotating shaft 4, an impeller 5 and a crushing assembly 6; at least two columns 2 are obliquely installed on the support base 1, the chamber 3 is assembled on the upper end surfaces of at least two columns 2, the rotating shaft 4 is vertically rotatably connected to the inside of the chamber 3, the impeller 5 is arranged on the outside of the rotating shaft 4, and the crushing assembly 6 is arranged at the bottom of the chamber 3.

[0027] In actual use, a crushing assembly 6 is installed at the bottom water inlet end of the chamber 3. That is, when the motor assembly 8 is running, the crushing assembly 6 crushes the larger media in the sewage to ensure that the sewage drawn into the chamber 3 does not affect the normal rotation of the impeller 5.

[0028] In actual settings, large media are broken down into smaller particles through the crushing assembly 6, and the quality of sewage entering the chamber 3 is improved, which helps to reduce pipe blockage and damage to other sewage treatment equipment, thereby improving the stability and reliability of the entire system. In addition, by reducing the presence of large media, the system's ability to treat sewage is enhanced, thereby improving the efficiency and speed of the entire treatment process.

[0029] It should be noted that a support frame 7 is installed on the top of the chamber 3 , and a motor assembly 8 whose output end is drivingly connected to the rotating shaft 4 is mounted on the support frame 7 .

[0030] In actual use, the motor assembly 8 drives the rotating shaft 4 to rotate, thereby driving the components in the crushing assembly 6 to rotate, so that the large medium can be crushed.

[0031] See also Figure 2-3In order to effectively crush large media, the crushing assembly 6 in this embodiment includes an inlet pipe 601, a top plate 602, at least two partition columns 603, a bottom plate 604, a transmission rod 605 and at least two crushing plates 606; the inlet pipe 601 is connected to the bottom of the chamber 3, the top plate 602 is sleeved on the outside of the inlet pipe 601, at least two partition columns 603 are assembled on the lower surface of the top plate 602, the bottom plate 604 is assembled on the bottom ends of the at least two partition columns 603, the transmission rod 605 is transmission-connected to the rotating shaft 4, and at least two crushing plates 606 are arranged in a ring on the outside of the transmission rod 605.

[0032] In actual settings, the transmission rod 605 is driven to rotate by the motor assembly 8, thereby driving the crushing plate 606 to rotate. The annular arrangement of the crushing plates 606 allows large media to be fully crushed. When large media such as branches in sewage flow with the water flow, they will be captured by the crushing plates 606 and effectively crushed during the rotation process.

[0033] Furthermore, the operation of the crushing assembly 6 is relatively simple. The crushing plate 606 can be rotated by driving the transmission rod 605 through the motor assembly 8. This design makes the maintenance and operation of the system more convenient and reduces manpower and time costs.

[0034] In actual use, the motor assembly 8 drives the transmission rod 605 connected to it to rotate, thereby driving the crushing plate 606 on the outer surface of the transmission rod 605 to rotate. That is, when the branch-like medium flows with the water flow, the branches are inserted between two adjacent partition columns 603. At the same time, the crushing plate 606 can crush the branches between the partition plates 603 during the rotation process.

[0035] In addition, the crushed branches will be transported to the inside of the water inlet pipe 601 along with the water flow and enter the inside of the chamber 4. In order to facilitate the discharge of sewage, a drainage pipe is connected to the outer peripheral surface of the chamber 3, that is, the extracted sewage will be discharged through the drainage pipe.

[0036] It should be noted that at least two partition columns 603 are distributed in a circular array between the bottom plate 604 and the top plate 602 , and the partition columns 603 are made of stainless steel.

[0037] In actual settings, the partition columns 603 are arranged in a circular array between the bottom plate 604 and the top plate 602, ensuring uniform distribution of the partition columns 603 in the entire crushing assembly 6, helping to provide uniform support and stability, and preventing uneven force on the crushing plate 606 during rotation, thereby increasing the reliability and life of the system.

[0038] In addition, the partition column 603 made of stainless steel has high strength and corrosion resistance. Stainless steel is not easy to rust in a humid environment and can resist corrosion, thereby extending the service life of the partition column and ensuring that the crushing component 6 can maintain structural stability and strength during long-term operation.

[0039] Furthermore, the distance between two adjacent partition columns 603 does not exceed one centimeter, and a gap of no more than 0.5 centimeters is retained between the crushing plate 606 and the partition column 603.

[0040] In actual settings, by limiting the distance between two adjacent partition columns 603 to no more than one centimeter and maintaining a gap of no more than 0.5 centimeters between the crushing plate 606 and the partition column 603, the crushing process of the medium in the sewage by the crushing plate can be precisely controlled. This fine control helps to ensure that the medium is evenly crushed and maintain efficient operation of the system.

[0041] In addition, the spacing control can effectively prevent the medium in the sewage from being blocked or stuck during the crushing process. The spacing between adjacent partition columns 603 and the gap between the crushing plate 606 and the partition column 603 prevent large media from passing through them, thereby reducing the risk of system blockage and improving the stability and reliability of the system.

[0042] Furthermore, in order to ensure the stability of the driving rod 605 during rotation, the bottom end of the driving rod 605 in this embodiment is rotatably connected to the center of the upper surface of the bottom plate 604 .

[0043] In actual settings, connecting the bottom end of the transmission rod 605 to the center of the surface of the bottom plate 604 can ensure that the transmission rod 605 remains balanced during rotation. Since the center of the surface of the bottom plate 604 is usually a stable point, this connection method can minimize unnecessary shaking or vibration of the transmission rod 605 during rotation, thereby improving the stability of the system.

[0044] The present application also provides a vertical sewage pump, which is implemented according to the base described above, and includes a motor assembly 8 and a rotating shaft 4 and an impeller 5 rotatably connected inside a chamber 4 .

[0045] In summary, the base and vertical sewage pump:

[0046] By breaking up large media into smaller particles through the crushing assembly 6, the quality of sewage entering the chamber 3 is improved, which helps reduce pipe blockage and damage to other sewage treatment equipment, thereby improving the stability and reliability of the entire system. In addition, by reducing the presence of large media, the system's ability to treat sewage is enhanced, thereby improving the efficiency and speed of the entire treatment process. The motor assembly 8 drives the transmission rod 605 to rotate, thereby driving the crushing plate 606 to rotate. The annular arrangement of the crushing plate 606 allows large media to be fully crushed. When large media such as branches in the sewage flow with the water, they will be captured by the crushing plate 606 and effectively crushed during the rotation process.

[0047] 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.
