Description

Technical Field

[0001] This utility model relates to the field of drainage pump technology, specifically a sewage interception and drainage pump. Background Technology

[0002] Existing drainage pump systems generally employ filters, screens, or sieves to initially intercept and remove impurities from wastewater. These traditional drainage pump designs typically include a fixed screen or screen structure that filters out large particles of impurities from the water through the flow of the liquid. The drainage pump delivers clean water through a simple filtration system, while impurities are trapped in the screen or screen. However, the efficiency of this design is often limited by the size of the screen aperture, the type of impurities, and the susceptibility of the filter to clogging, leading to reduced pump efficiency and increased maintenance costs.

[0003] In traditional designs, impurities typically accumulate on filter screens or grilles, affecting drainage efficiency and requiring regular cleaning to maintain pump operation. Excessive impurity buildup can limit pump performance, leading to reduced water flow or pump damage. Existing technologies often fail to efficiently divert and remove larger particles or viscous substances. Therefore, this study aims to address these issues by developing a wastewater interception and drainage pump to solve current problems and enhance practical value. Utility Model Content

[0004] This utility model discloses a wastewater interception and drainage pump, aiming to provide a drainage pump with optimized structure, high drainage efficiency, and good wastewater interception effect. To achieve this objective, this utility model includes the following technical solutions:

[0005] A wastewater interception and drainage pump includes: a fixed base, a crushing bucket, and a drainage pump assembly. A wastewater discharge box is fixedly installed inside the fixed base. Several wastewater discharge cylinders are fixedly connected to the surface of the wastewater discharge box, and discharge shafts are rotatably installed inside the discharge cylinders. A drive motor is fixedly installed on the surface of the fixed base, and the output end of the drive motor is driven by a synchronous belt for synchronous transmission of the various discharge shafts. A filter plate is fixedly installed inside the wastewater discharge box. The drainage pump assembly includes a pump housing and an axial flow impeller rotatably installed inside the pump housing. One end of the axial flow impeller is driven by the surface of the synchronous belt. An inlet is opened on the surface of the pump housing, and the inlet faces the surface of the filter plate. By employing the cooperation of multiple wastewater discharge cylinders and discharge shafts, impurities can be effectively diverted and discharged from the drainage liquid. The filter plate inside the wastewater discharge box further improves the impurity treatment effect, thereby improving the wastewater interception capacity and working efficiency of the drainage pump. This structure ensures that the pump maintains good wastewater interception performance even under high load operation and avoids impurity clogging.

[0006] In a preferred embodiment, this invention can be further configured such that the discharge shaft is inclined and the horizontal height of the discharge port is higher than the horizontal height of the top surface of the inlet, with the outer periphery of the discharge cylinder slidingly abutting against the inner side of the discharge shaft. By setting the discharge shaft to an inclined arrangement, impurities can be discharged from the discharge cylinder under the action of the discharge shaft. During the discharge process, the height difference between the two ends of the discharge shaft is used to prevent water from being discharged, thus achieving separation of water and impurities. At the same time, the sliding contact between the outer periphery of the discharge cylinder and the discharge shaft ensures that impurities can be smoothly discharged, maintaining the long-term efficient operation of the pump.

[0007] In a preferred embodiment, this invention can be further configured such that pulleys are provided at the ends of both the pump housing and the discharge shaft, and a synchronous belt is connected to the surface of each pulley for transmission. The pulley configuration achieves efficient transmission between the pump housing and the discharge shaft. This ensures that all components of the drainage pump operate synchronously during operation, enhancing the pump's efficiency and stability, especially under high-load conditions.

[0008] In a preferred embodiment, the present invention can be further configured such that: the filter plate has an inverted V-shaped structure, and the outer periphery of the filter plate is fixedly connected to the inner side of the sewage box; the water inlet is connected to the inner side of the sewage box and the connecting opening faces the filter plate.

[0009] The inverted V-shaped structure of the filter plate effectively guides impurities in the wastewater to the discharge cylinder and discharge shaft for treatment, thereby improving the filtration effect of the drainage pump. This design not only reduces clogging of the filter plate surface by impurities but also allows purified water to flow out smoothly, improving the water purification efficiency of the drainage pump.

[0010] In a preferred embodiment, this invention can be further configured such that the sewage discharge cylinder and discharge shaft are in several groups and symmetrically distributed about the drainage pump assembly and the filter plate. By distributing the sewage discharge cylinder and discharge shaft in a symmetrical structure, impurities inside the drainage pump can be evenly distributed, improving the sewage discharge effect and ensuring the pump's stable operation and efficiency.

[0011] In a preferred embodiment, this invention can be further configured such that: the crushing hopper is fixed to the top of the fixed base and its bottom is connected to the sewage box; two crushing rollers are rotatably mounted on the inner side of the crushing hopper, and the two crushing rollers are mutually driven and meshed; the surface of the crushing hopper is provided with a reduction motor for driving the two crushing rollers to rotate in opposite directions. By setting a rotating device inside the crushing hopper, the crushing rollers can be driven to rotate and mesh with each other, performing shearing and crushing of larger impurities, further enhancing the sewage discharge capacity of the drainage pump.

[0012] The beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, water and impurities are separated by a sewage discharge box, and the impurities in the sewage can be effectively diverted and discharged through the cooperation of multiple sewage discharge cylinders and discharge shafts, thereby improving the sewage interception effect and drainage efficiency of the drainage pump.

[0014] 2. In this utility model, by setting the filter plate inside the sewage box to an inverted V-shaped structure and fixing it to the inside of the sewage box, the impurities in the sewage can be fully guided to the sewage discharge cylinder and discharge shaft for treatment and the clogging of the filter plate surface can be avoided. At the same time, the clean water can be smoothly discharged through the filter plate and the drainage pump group, which significantly improves the sewage treatment capacity and filtration efficiency of the drainage pump.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0024] The following is in conjunction with the appendix Figures 1-5 This invention describes a wastewater interception and drainage pump provided by some embodiments of the present invention. Example 1

[0025] This embodiment provides a specific structure and operating method of a wastewater interception and drainage pump. According to claim 1, the structure includes a fixed base 100, a crushing hopper 200, and a drainage pump assembly 300. A wastewater discharge box 120 is fixedly installed inside the fixed base 100. A plurality of wastewater discharge cylinders 130 are fixedly connected to the surface of the wastewater discharge box 120, and a discharge shaft 140 is rotatably installed inside the wastewater discharge cylinders 130. A filter plate 121 inside the wastewater discharge box 120 serves to divert impurities, ensuring that impurities in the wastewater are discharged through the wastewater discharge cylinders 130, and that clean water passes through the filter plate 121 and enters the drainage pump assembly 300 for discharge. The drainage pump assembly 300 includes a pump housing 310 and an axial flow propeller 320 rotatably installed inside the pump housing 310. One end of the axial flow propeller 320 is connected to the surface of a synchronous belt 111, thereby driving the rotation of the drainage pump assembly and ultimately discharging the clean water.

[0026] In actual operation, when sewage enters the discharge box 120, it is diverted by the filter plate 121, and impurities in the water are diverted to the discharge cylinder 130 and the discharge shaft 140, where they are discharged. Clean water enters the pump box 310 through the filter plate 121 and is discharged by the axial flow propeller 320.

[0027] The advantage of this embodiment is that by arranging the filter plates 121 inside the sewage box 120, impurities in the sewage can be effectively diverted, and the impurities can be discharged through the sewage discharge cylinder 130 and the discharge shaft 140, thereby greatly improving the efficiency of sewage interception and drainage.

[0028] In this embodiment, two crushing rollers 210 are rotatably mounted on the inner side of the crushing bucket 200, and the two crushing rollers 210 are mutually driven and meshed. The surface of the crushing bucket 200 is provided with a reduction motor for driving the two crushing rollers 210 to rotate in opposite directions. By setting a rotating device inside the crushing bucket 200, the crushing rollers 210 can be driven to rotate and mesh with each other to perform shearing and crushing of larger impurities, further enhancing the sewage discharge capacity of the drainage pump. Example 2

[0029] This embodiment further optimizes the design of the sewage interception and drainage pump. Compared with Embodiment 1, Embodiment 2 uses a different drive motor and transmission method in the drive section of the drainage pump. The drive motor 110 drives the discharge shaft 140 to rotate via a synchronous belt 111 for drainage operations. The sewage discharge cylinder 130 and the discharge shaft 140 are arranged at an angle to ensure that impurities can be smoothly separated and discharged during the sewage discharge process. In particular, the outer periphery of the sewage discharge cylinder 130 slides against the inner side of the discharge shaft 140, further enhancing the sewage discharge efficiency during the drainage process.

[0030] The advantage of this embodiment is that by improving the drainage efficiency and operational stability of the drainage pump, the separation and removal process of impurities is optimized, and the adaptability of the drainage pump in complex environments is improved, ensuring long-term reliability and high efficiency.

[0031] The above-described embodiments 1 and 2 both demonstrate the superior performance of this utility model. By rationally arranging the sewage box 120 and its internal sewage cylinder 130 and discharge shaft 140, combined with the design of the high-efficiency drainage pump set 300, good sewage discharge and drainage effects are achieved. Different drive motors and synchronous belt 111 transmission methods improve working efficiency and reduce operating noise. The overall structural design is simple and efficient, adaptable to various complex sewage discharge environments.
