Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, and in particular to a transmission body structure for a mine sewage pump. Background Technology

[0002] Mining wastewater pumps are water pumps specifically designed for mining environments. They are used to extract wastewater containing impurities such as mud and slag generated during mining operations, ensuring the stable operation of mining wastewater treatment and drainage systems.

[0003] Mining processes generate large amounts of wastewater containing solid particles and suspended solids. Existing wastewater pumps typically employ a curved flow channel design. This curved channel provides poor guidance for solid particles (such as silt and coal dust), leading to severe wear on the channel walls, shortening service life. The design also reduces the flow area and flow capacity, impacting wastewater treatment efficiency. Large particles easily accumulate at channel bends, causing pump blockages and requiring frequent shutdowns for cleaning. Furthermore, the fixed connection between the diffuser and pump body makes it difficult to adapt to varying conduit diameter requirements under different operating conditions. Therefore, this paper proposes a new flow channel structure for mining wastewater pumps to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a transmission body structure for mine sewage pumps, aiming to improve the problems of easy wear, risk of clogging, and insufficient adaptability of the transmission body structure for sewage pumps in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a transmission body structure for a mine sewage pump, comprising a main body, wherein six liquid flow channels are evenly distributed in a ring inside the main body, a precision sealing groove is provided on the front side of the main body, and six high-precision inner straight openings are evenly distributed in a ring in the middle of the rear side of the main body.

[0006] As a further description of the above technical solution:

[0007] The surface of the main body has six mounting holes arranged in a ring.

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

[0009] The precision sealing groove is annular.

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

[0011] The liquid flow channel is in a multi-segment spiral shape.

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

[0013] The liquid flow channel gradually expands from the inlet to the outlet.

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

[0015] The main body has a central hole.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the internal flow channel of the mine sewage pump transmission body adopts a multi-segment spiral flow channel design, which gradually expands from the inlet to the outlet to ensure that the fluid speed gradually decreases during the flow process, thereby reducing kinetic energy loss, increasing the flow area, increasing the flow capacity, and reducing the risk of blockage.

[0018] 2. In this utility model, the transmission body structure of the mine sewage pump 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.

[0024] 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.

[0025] Reference Figures 1-3The present invention provides an embodiment of a transmission body structure for a mine sewage pump, comprising a main body 1. The interior of the main body 1 has six liquid flow channels 2 evenly distributed in a ring for liquid flow and guidance. A precision sealing groove 3 is provided on the front side of the main body 1. The sealing groove cooperates with the pipeline to form a sealing structure to prevent internal liquid from leaking outward. Six high-precision inner straight ports 5 are evenly distributed in a ring in the middle of the rear side of the main body 1. They are precisely machined with a special wear plate to achieve a sealing fit and prevent liquid from leaking from the inlet.

[0026] Reference Figure 2 and Figure 3 The surface of the main body 1 has six mounting holes 4 arranged in a ring, including three round holes and three inner circles of the column, which are connected to the special diffuser to ensure the positioning accuracy and structural stability of the transmission body during installation.

[0027] Reference Figure 1 The precision sealing groove 3 is annular, and the annular structure allows the sealing groove to form a continuous sealing interface around the main body 1, improving the overall sealing reliability.

[0028] Reference Figure 3 The liquid flow channel 2 is in a multi-segment spiral shape. The multi-segment spiral shape can gradually reduce the velocity of the fluid during the flow process, reduce kinetic energy loss and improve flow efficiency.

[0029] Reference Figure 3 The liquid flow channel 2 gradually expands from the inlet to the outlet. The gradual expansion design of the flow channel cross section can increase the flow area and improve the transmission body's ability to pass through high-concentration solid particle media.

[0030] Reference Figure 3 The main body 1 has a central hole 6, which provides a central flow path for the fluid, optimizes the overall flow field distribution, and helps the fluid to transition smoothly.

[0031] Working Principle: This transmission body structure is suitable for wastewater discharge scenarios containing high concentrations of solid particles and corrosive media. The liquid flow channel 2 inside the main body 1 adopts a multi-segment spiral flow channel design, which gradually expands from the inlet to the outlet, ensuring that the fluid velocity gradually decreases during the flow process, reducing kinetic energy loss, increasing the flow area, and increasing the flow capacity. The precision sealing groove 3 of the main body 1 cooperates with the pipeline seal to ensure that the liquid inside the whole machine does not leak. The six mounting holes 4 of the main body 1 include three round holes and three column inner circles, which cooperate with another special diffuser to ensure the stability of the whole machine installation. The high-precision inner straight port 5 of the main body 1 cooperates with the special wear disc seal to ensure that the liquid does not leak at the inlet. The transmission body is made of duplex steel to ensure the wear resistance and corrosion resistance of the parts, ensuring the normal operation and service life of the wastewater pump.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
