Description

Technical Field

[0001] This utility model belongs to the field of mud pump casing technology, and in particular relates to a pump casing structure. Background Technology

[0002] Mud pumps are key equipment for conveying media with high concentration, high viscosity and containing solid particles, and are widely used in mining, metallurgy, dredging, ceramics and other industrial fields.

[0003] Currently, most mud pumps lack dedicated protective casings. In actual operation, without protection, the structure easily leads to stagnant mud and sedimentation zones within the pump. Continuous mud deposition reduces the effective flow area, significantly decreasing pump head and efficiency, increasing energy consumption. More seriously, uneven deposition can cause dynamic imbalances in rotor components such as the impeller, resulting in severe vibration and noise, significantly impacting the lifespan of bearings and mechanical seals, posing significant safety hazards. Furthermore, after shutdown, the deposited mud hardens, potentially causing pump blockage or even motor burnout upon restarting. Cleaning and maintenance are exceptionally cumbersome and difficult, increasing downtime and maintenance costs. Therefore, existing mud pump technologies have significant shortcomings in terms of sediment prevention, safety, and ease of maintenance, urgently requiring a new pump casing structure that effectively prevents mud deposition, ensures operational safety, and facilitates cleaning.

Its unique structural layout creates a smooth drainage channel for the mud outside the pump casing, significantly reducing stagnant areas and preventing the accumulation and caking of mud particles. Simultaneously, the easily accessible maintenance pipeline greatly facilitates daily inspection and cleaning, significantly reducing downtime and maintenance costs. This device excels in improving equipment operational safety. By preventing uneven sedimentation, it effectively avoids dynamic imbalance of rotor components such as the impeller, thereby reducing unit vibration and noise, extending the service life of mechanical seals and bearings, and eliminating potential safety hazards. Furthermore, the reinforced sealing design ensures the reliability of the pump casing connection, further improving the overall operational stability of the equipment.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1, such as Figure 1-6 As shown below, the specific design of the above key components is described in detail. A pump casing structure includes a cylindrical shell 1, a conical shell 2 threadedly connected to the top of the cylindrical shell 1, a mud pump placed inside the conical shell 2, a conical lower shell opening 10 provided below the cylindrical shell 1, a sealing ring 11 provided on the lower shell opening 10 to enhance the sealing effect, a maintenance pipe 4 provided on one side of the cylindrical shell 1, the maintenance pipe 4 communicating with the interior of the cylindrical shell 1, and a sealing cover 5 provided on the maintenance pipe 4.

[0019] The pump casing structure optimizes mud flow and equipment maintenance through its unique split and conical shell 2 design. During operation, the mud pump is placed inside the cylindrical shell 1, and the output end of the mud pump extends out of the cylindrical shell 1 through the lower shell opening 10. The threaded conical shell 2 and cylindrical shell 1 form a main cavity that can be easily separated. When installation, disassembly, or cleaning is required, the operator can unscrew the connection. During maintenance, the side maintenance pipe 4 sealing cover 5 can also be opened directly. The resulting spacious passage allows personnel or tools to directly enter the pump casing for efficient removal of sediment without the need for large-scale disassembly of the entire pump body. This design prevents accumulation when the conical shell 2 comes into contact with mud and water, while the shape of the cylindrical shell 1 fits the mud pump. The reasonable layout facilitates both the storage of the mud pump and the downward flow of mud, ensuring unobstructed flow, maintaining the head and efficiency of the mud pump, reducing unnecessary energy consumption, and preventing impeller dynamic imbalance caused by uneven deposition. This greatly reduces unit vibration and noise, extends the service life of key components such as bearings and mechanical seals, and fundamentally improves operational safety. The easily openable design greatly simplifies daily maintenance and cleaning operations, significantly shortens downtime, and reduces long-term maintenance costs. The overall structure combines high efficiency, safety, and ease of maintenance.

[0020] The cylindrical shell 1 has multiple hollow tubes 3 arranged in an array on its outer periphery, and multiple floats 8 arranged in an array on its outer periphery of the lower shell opening 10. Airbags 9 are installed on the floats 8. The cylindrical shell 1 has an inner lining layer 12 on its inner periphery. Both the cylindrical shell 1 and the conical shell 2 are made of high-strength stainless steel with a wall thickness of 8-12mm. The cone angle of the lower shell opening 10 is 30-45 degrees and is made of wear-resistant alloy steel with a wall thickness of 10-15mm. A handle 7 is provided on the top of the cylindrical shell 1, and a lifting ring 6 is provided on one side of the cylindrical shell 1.

[0021] The pump casing structure employs multiple innovative designs working in synergy to enhance overall performance. The outer hollow tube 3 not only reduces overall weight but also allows mud to flow out after entering the pump. Furthermore, the symmetrical arrangement of the hollow tubes 3 effectively maintains the casing's balance and facilitates mud removal. The float plate 8 and air bladder 9 around the lower casing opening 10 can be inflated according to operational needs, providing controllable buoyancy to the entire pump body. This significantly reduces the agitation and impact on sediment at the bottom of mud pits and other working conditions, while also mitigating the risk of direct contact between the pump body and mud. The inner lining 12, in direct contact with the mud pump, not only buffers pump vibration but also protects the main structure with its high wear resistance. The upper handle 7 and the side lifting ring 6 together form a safe and efficient operable handle 7 and lifting system, facilitating installation and transportation.

[0022] This design offers several significant advantages. The buoyancy system effectively prevents the pump body from sinking, greatly reducing starting resistance and vibration, and improving operational stability and efficiency. Combined with the internal wear-resistant lining and external heat dissipation hollow pipe, it significantly extends the service life of the pump casing under harsh operating conditions. The split structure and heat dissipation design prevent deformation caused by thermal stress, ensuring long-term sealing reliability. In addition, dedicated handles and lifting rings make the handling and installation of this heavy equipment safe and convenient, significantly reducing the labor intensity and operational risks for operators, and comprehensively improving the practicality and economy of the equipment.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
