Description

Technical Field

[0001] This utility model relates to an explosion-proof device for a slurry pump. Background Technology

[0002] Slurry pumps, in terms of their working principle, belong to the category of centrifugal pumps. Conceptually, they are machines that increase the energy of a solid-liquid mixture by utilizing centrifugal force (the rotation of the pump impeller), converting electrical energy into the kinetic and potential energy of the medium. The name "slurry pump" refers to a type of centrifugal pump categorized from the perspective of the medium being transported. Furthermore, slurry pumps can be further classified into different types based on various perspectives. Generally, pumps suitable for transporting liquids (water) containing suspended solids are called slurry pumps. Currently, they are an indispensable piece of equipment in various processes of mineral processing and coal preparation plants. Slurry pumps can be classified according to different principles into single-stage or multi-stage, single-suction or double-suction, cantilever, horizontal or vertical, and pump casings with horizontal split-opening or vertical combination, etc.

[0003] Slurry pumps pose a risk of explosion during use. The authorized Chinese utility model patent (publication number: CN217633113U, title: An Explosion-proof Device for a Slurry Pump) describes a device that uses an anti-rust layer to prevent rusting of the casing, improving the pump's quality. It also mentions a fixing block to enhance the stability and lifespan of the outlet pipe, and threaded holes and rods to secure the fixing block and outlet pipe, thus reinforcing the pipe and preventing explosion. However, the primary cause of slurry pump explosions is the entry of large, hard foreign objects into the pump. Relying solely on rust prevention for the casing leaves a significant risk of explosion during operation. Utility Model Content

[0047] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0048] Figures 1 to 5 The diagram shown is a structural schematic of an embodiment of the explosion-proof device for slurry pumps according to this utility model. The explosion-proof device for slurry pumps includes a slurry pump body 1.

[0049] Protective cover 2, the protective cover 2 is disposed on the outside of the slurry pump body 1, and the position of the protective cover 2 is adjustable;

[0050] The control component 3 is connected to the outer side of the protective cover 2 and the slurry pump body 1 respectively. The control component 3 is used to adjust and lock the position of the protective cover 2.

The explosion-proof mechanism 4 is used to crush and filter the material entering the slurry pump body 1, thereby achieving the explosion-proof function by preventing large-volume materials from entering the slurry pump body 1.

[0052] In this technical solution, the explosion-proof mechanism 4 can filter and crush large-volume materials, further preventing the hard material from damaging the internal components of the slurry pump body 1, increasing the explosion-proof performance of the slurry pump body 1, and crushing and separating large air bubbles in the material, preventing large air bubbles from affecting the smoothness of the material flow, thus facilitating the use of the slurry pump and giving the slurry pump better explosion-proof performance.

[0053] The slurry pump body 1 includes a first outer shell 11 and a second outer shell 12. Multiple connecting blocks 13 are provided on the outer sides of both the first outer shell 11 and the second outer shell 12. Two connecting blocks 13 whose central axes are on the same straight line are connected by a group of connecting bolts 14.

[0054] The first outer shell 11 and the second outer shell 12 are detachably connected to the connecting bolt group 14 via the connecting block 13.

[0055] In this technical solution, the first outer casing 11 and the second outer casing 12 can be installed and disassembled, which facilitates the maintenance of the slurry pump body 1.

[0056] The slurry pump body 1 also includes an inlet pipe 15 and a discharge pipe 16. The inlet pipe 15 is connected to the slurry pump body 1, and the discharge pipe 16 is connected to the second outer casing 12.

[0058] The control component 3 includes a fixed track 31, which is connected to the outside of the slurry pump body 1, and a sliding collar 32 is slidably connected to the surface of the fixed track 31.

[0059] The sliding collar 32 is connected to a connector 33 on the side away from the slurry pump body 1, and the side of the connector 33 away from the sliding collar 32 is connected to the inner wall of the protective cover 2.

[0060] In this technical solution, the position of the protective cover 2 can be adjusted using the control component 3.

The locking bolt 34 is threadedly connected to the sliding collar 32 and the fixed track 31 through the threaded hole and the threaded groove, respectively.

[0062] In this technical solution, the position of the protective cover 2 can be locked using the locking bolt 34.

[0063] In use, depending on the position of the object or human body, the sliding collar 32 can be moved along the fixed track 31, thereby driving the connecting piece 33 and the protective cover 2 to move in the same direction, thus moving the protective cover 2 to the position that needs protection. Then, the fixed track 31 and the sliding collar 32 are connected by the locking bolt 34, thereby locking the position of the protective cover 2 and facilitating its use.

[0064] The explosion-proof mechanism 4 includes an outer frame shell 41, which is connected to the end of the inlet pipe 15 away from the first outer shell 11.

[0065] A filter screen 42 is connected to the opening on the side of the outer frame 41 of the mechanism near the inlet pipe 15.

[0066] In this technical solution, the explosion-proof mechanism 4 can be used to filter and crush the material entering the slurry pump body 1, thereby increasing the explosion-proof performance of the slurry pump and improving the safety performance of the slurry pump during use.

[0067] The explosion-proof mechanism 4 includes a central shaft 43, one end of which is rotatably connected to the inner wall of the outer frame shell 41 of the mechanism, and the other end of which is rotatably connected to the side of the outer frame shell 41 of the mechanism.

[0070] A power source 46 is installed on the upper part of the outer frame shell 41 of the mechanism, and the output end of the power source 46 is connected to the upper end of the central shaft 43.

[0071] The power source 46 is an electric motor or other device that can output rotational kinetic energy.

[0072] In this technical solution, the power source 46 can provide driving force for the rotation of the anti-clogging soft brush 45.

[0073] A cutting blade 47 is installed inside the stirring frame 44.

[0074] In this technical solution, the cutting tool 47 can be used to crush the material entering the slurry pump body 1.

[0075] The cutting blade 47 includes a large cutting blade 471 and a small cutting blade 472. A plurality of transversely distributed large cutting blades 471 are fixed to the inner wall of the stirring frame 44, and a plurality of longitudinally distributed small cutting blades 472 are connected between adjacent large cutting blades 471.

[0076] In this technical solution, the large cutting blade 471 and the small cutting blade 472 can effectively crush larger and harder materials, and at the same time crush larger air bubbles, which facilitates the transportation of materials by the slurry pump.

[0077] During use, the material enters the inlet pipe 15 through the outer frame shell 41 of the mechanism, and then enters the slurry pump body 1. When the material is in the outer frame shell 41 of the mechanism, it is filtered by the filter screen 42.

[0078] During filtration, the power source 46 drives the central shaft 43 to rotate, thereby driving the stirring frame 44 and the anti-clogging soft brush 45 to rotate. The anti-clogging soft brush 45 cleans the filter screen 42 to prevent clogging and affect its use.

[0079] Before filtration, the rotation of the central shaft 43 can drive the large cutting blade 471 and the small cutting blade 472 to rotate. The rotating large cutting blade 471 and the small cutting blade 472 are used to break and separate larger and harder objects and larger air bubbles, thereby preventing larger and harder objects and larger air bubbles from causing the slurry pump to burst and improving the explosion-proof performance of the slurry pump.
