Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a submersible reflux pump with a cutting function. Background Technology

[0002] In fields such as sewage treatment, aquaculture, and industrial wastewater recycling, submersible reflux pumps are core equipment for water flow and circulation, and are required to handle complex water bodies containing particulate impurities, fibrous debris, and flexible impurities over long periods of time.

[0003] A search revealed CN213711317U, a submersible reflux pump with a cutting function, comprising a pump body, a rotating shaft, connecting rods, and a brush plate. One end of the pump body has a discharge hole for connecting to a sewage pipe, and a mesh cover is provided on the outer circumferential surface of the pump body. A protective outer shell is sealed on the outer circumferential surface of the pump body. The protective outer shell has multiple sets of first through holes. The other end of the protective outer shell has multiple sets of stabilizing support rods. The rotating shaft is located inside the protective outer shell, with one end extending into the pump body from the other end and connecting to a rotating shaft inside the pump body. Multiple sets of first pulverizing blades are evenly distributed on the rotating shaft located inside the protective outer shell. A circular brush plate is located inside the pump body, with the brush plate and rotating shaft arranged concentrically. Bristles are evenly distributed on the end face of the brush plate facing the mesh cover; the bristles press against the mesh cover. Multiple connecting rods connect the outer circumferential surface of the rotating shaft and the inner circumferential surface of the brush plate. This utility model is simple to operate and convenient to use, capable of pulverizing impurities carried in sewage to be discharged from sewage tanks before discharge, avoiding blockages.

[0004] In the aforementioned device, a motor drives a rotating shaft to rotate, causing multiple sets of first crushing blades fixed on the shaft to engage with second crushing blades inside the protective casing of the submersible return pump's inlet. This shearing or impact action breaks up debris entering the inlet, reducing the probability of large debris entering the pump body. However, in different application scenarios, the size and hardness of debris in the water vary significantly. It's impossible to adjust the distance between the first and second crushing blades according to the actual characteristics of the debris. If the distance is too large, small and medium-sized debris can easily pass through the gap and enter the pump body; if the distance is too small, debris tends to accumulate in the gap, blocking the water flow channel. This makes the device unsuitable for the characteristics of debris in various scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide a submersible reflux pump with a cutting function to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a submersible reflux pump with a cutting function, comprising:

[0007] Pump body;

[0008] The adjusting component includes a fixing ring, an inner groove, a guide rod, a vertical plate, and a guide slot. Two sets of fixing rings are located at the lower part of the inner surface of the pump body. The inner groove is opened at both ends of the outer surface of the fixing ring.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Please see Figure 1-6 As shown, this utility model is a submersible reflux pump with a cutting function, comprising:

[0032] Pump body 11;

[0033] A submersible reflux pump is a fluid device that operates underwater to promote the circulation of water. Its core function is to use mechanical power to create a directional reflux of water, eliminating dead zones and improving mixing efficiency. It is widely used in wastewater treatment, aquaculture, and landscape water body maintenance. Its operating principle revolves around three core aspects: power transmission, fluid drive, and reflux control, and requires understanding in conjunction with structural design and fluid mechanics principles.

[0034] The adjusting component includes a fixing ring 23, an inner groove 24, a guide rod 25, a vertical plate 26, and a guide groove 27. Two sets of fixing rings 23 are set at the lower part of the inner surface of the pump body 11. The inner groove 24 is opened at both ends of the outer surface of the fixing rings 23. The guide rod 25 is fixed in the middle of the inner surface of the inner groove 24. The guide groove 27 is opened inside the vertical plate 26. The outer surface of the guide rod 25 is slidably connected to the inside of the guide groove 27.

[0035] Two sets of fixing rings 23 slide within the guide groove 27 of the upright plate 26 via guide rods 25, allowing for flexible adjustment of the spacing between the upper fixing ring 23, the lower fixing ring 23, and the mesh plate 22. For wastewater treatment plants containing a large amount of long fibers, the spacing can be reduced to tightly clamp the fiber debris between the fixing rings 23 and the mesh plate 22, preventing the fibers from bypassing the crushing area due to excessive gaps. For aquaculture farms containing a large amount of particulate impurities, the spacing can be increased to prevent particles from accumulating and clogging in small gaps, significantly improving the adaptability of debris in various scenarios.

[0036] A support ring 21 is fixedly connected to the inner surface of the pump body 11, and a mesh plate 22 is detachably connected to the inner wall of the support ring 21.

[0037] The mesh of the screen plate 22 first intercepts large-sized debris and retains it near the fixing ring 23, providing a pool of material to be crushed for the cutting blade 31.

[0038] The inner surface of the fixing ring 23 is provided with internal threaded rings 33 at both ends. The middle of the internal threaded ring 33 is threadedly connected to a threaded rod 34. The outer end of the threaded rod 34 is fixedly connected to a handle 35. The end of the threaded rod 34 abuts against the outer surface of the upright plate 26.

[0039] By limiting the sliding of the guide rod 25 in the guide groove 27 through friction, the positions of the upper fixing ring 23 and the lower fixing ring 23 are locked, ensuring that the spacing during subsequent cutting operations will not shift due to water flow impact or vibration.

[0040] A rotating rod 32 is provided on the upper part of the inner surface of the fixed ring 23. A cutting blade 31 is fixedly connected to the outer wall of the rotating rod 32. A rotating shaft 36 is provided at the bottom of the rotating rod 32. A motor 37 is fixedly connected to the bottom of the rotating shaft 36.

[0041] Multiple sets of cutting blades 31 are uniformly fixed along the axial direction on the outside of the upper rotating rod 32, and rotate in the forward direction (such as clockwise) together with the rotating rod 32, forming an upward shearing airflow and water flow disturbance.

[0042] The cutting blades 31 outside the lower rotating rod 32 rotate in the opposite direction (such as counterclockwise) with the rotating rod 32, forming a downward shearing airflow and water flow disturbance.

[0043] A support rod 38 is welded between the fixed ring 23 and the motor 37, and the support rod 38 is evenly distributed.

[0044] The support rod 38 provides support between the fixed ring 23 and the motor 37.

[0045] Working principle:

[0046] First, the maintenance personnel observe the characteristics of the debris in the water. They manually push the upper and lower fixing rings 23 to slide along the guide grooves 27 on the inner side of the two vertical plates 26 to adjust the distance between the mesh plate 22, the upper fixing ring 23, and the lower fixing ring 23. Then, they turn the handle 35 to drive the threaded rod 34 to rotate along the middle of the inner threaded ring 33 on the outer side of the vertical plate 26 until the end of the threaded rod 34 is tightly against the outer surface of the vertical plate 26. The upper motor 37 is then started, and the motor 37 drives the coaxially connected upper rotating shaft 36 to rotate, which in turn drives the upper rotating rod 32 to rotate clockwise. The lower motor 37 is also started simultaneously, and the motor 37 drives the lower rotating shaft 36 to rotate, which in turn drives the lower rotating rod 32 to rotate in the opposite direction. The broken debris passes through the mesh of the mesh plate 22 with the water flow, and is then pressurized by the impeller assembly inside the pump body 11 before being discharged through the return branch pipe.

[0047] This step enables precise processing of impurities with different characteristics, ensuring both crushing efficiency and adaptability to various scenarios, thus ensuring stable operation of the equipment in multiple settings such as wastewater treatment and aquaculture.

[0048] Please see Figure 1-6 As shown, this embodiment, based on the above embodiment, further includes:

[0049] The fixing component includes a base 41, a positioning rod 44, a fastening ring 45, and a positioning hole 46. The base 41 is located at the bottom of the pump body 11, the positioning rod 44 is fixed at the bottom of the pump body 11, the positioning hole 46 is opened inside the base 41, the positioning rod 44 is inserted into the inside of the positioning hole 46, and the fastening ring 45 is threaded to the outside of the positioning rod 44.

[0050] By cooperating with the positioning rod 44 and the positioning hole 46, and with the pressing of the base 41 on the fixing ring 23, the fixing ring 23 is initially constrained in both the vertical and horizontal directions, preventing the fixing ring 23 from shifting position during subsequent tightening.

[0051] A retaining plate 43 is fixedly connected to one end of the outer surface of the upright plate 26, and a retaining groove 42 is provided on the inner surface of the pump body 11, and the retaining plate 43 is engaged inside the retaining groove 42.

[0052] Align the outer card plate 43 with the lower card slot 42, insert and lock it in place, so that the lower fixing ring 23 and the upper fixing ring 23 are installed parallel inside the pump body 11.

[0053] Working principle:

[0054] First, align the card plate 43 with the lower card slot 42, insert and tighten it, then align the base plate 41 with the bottom of the pump body 11 to cover it, so that the positioning holes 46 on the base plate 41 are inserted into the positioning rods 44 at the bottom of the pump body 11. When the fastening ring 45 rotates through the thread, the fastening ring 45 moves along the positioning rods 44 until the bottom of the fastening ring 45 is in close contact with the upper surface of the base plate 41.

[0055] This step provides a reliable structural foundation for the subsequent bidirectional crushing by the upper and lower fixing rings 23 in conjunction with the cutting blades 31.
