Description

Technical Field

[0001] This utility model relates to the field of sewage pump technology, and in particular to a wear-resistant conveying body structure for a mine sewage pump. Background Technology

[0002] Mining wastewater pumps operate in harsh environments characterized by high abrasion and corrosion, making critical components such as impellers, wear plates, and wear discs susceptible to failure due to impact from solid particles. Traditional materials like ordinary cast iron or low-alloy steel lack sufficient wear resistance, necessitating frequent replacements. While existing technologies utilize high-chromium cast iron (Cr15-Cr28) for wear-resistant parts, the following problems still exist:

[0003] Ordinary sand casting is prone to producing porosity and inclusions, which reduces the density and impact resistance of the material.

[0004] Ordinary cast iron or ordinary stainless steel has insufficient wear resistance and is easily deformed or cracked by the erosion of solid particles.

[0005] Mining operations generate large amounts of wastewater containing solid particles and suspended matter. Existing wastewater pumps use upper wear discs that are prone to wear, and their unreasonable structural design and insufficient support strength lead to a reduced service life, impacting wastewater treatment efficiency. Therefore, the market urgently needs a new type of upper wear disc for mining wastewater pumps to solve these problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a wear-resistant conveying body structure for a mine sewage pump, aiming to improve the problems of easy wear of the upper wear disc in the sewage pump in the prior art, unreasonable structural design, insufficient support strength leading to reduced device service life and low sewage treatment efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant conveying body structure for a mine sewage pump, comprising an outer shell, a base fixedly connected to the bottom of the outer shell, three sets of support units evenly distributed inside the outer shell, and reinforcing ribs provided inside the support units.

[0008] As a further description of the above technical solution:

[0009] A connecting shell is fixedly connected inside the outer shell.

[0010] As a further description of the above technical solution:

[0011] The connecting shell is internally connected to a stabilizing ring.

[0012] As a further description of the above technical solution:

[0013] The stabilizing ring is internally connected to a wear-resistant disc.

[0014] As a further description of the above technical solution:

[0015] The outer casing has three rotating shafts inside.

[0016] As a further description of the above technical solution:

[0017] The wear-resistant disc has a sealing groove fixedly connected to its exterior.

[0018] As a further description of the above technical solution:

[0019] The wear-resistant disc is provided with a locking block on its upper part.

[0020] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, three sets of support units are evenly distributed at 120° intervals, with three reinforcing ribs in each set. This constitutes an asymmetric load distribution mechanism, increasing the deformation resistance of the upper wear disc.

[0024] 2. In this utility model, the device is integrally cast, which ensures the installation accuracy and wear resistance of the product. The subsequent machining of the mating surfaces through integral precision casting reduces the production difficulty, improves production efficiency, and reduces production costs.
