The rear sheaths 52 are sealed together and located inside the conveying chamber. The front sheath 6 is connected to the front sheath 51 on its outer circumference and connected to the pump cover 3 on its end face. It is located inside the conveying chamber. The connecting pipe 7 is installed in the center of the front sheath 6. The feed pipe 8 is installed on the pump cover 3. The conveying chamber, the connecting pipe 7, and the feed pipe 8 are interconnected. The rotating shaft 9 is rotatably installed on the support base 1.

The discharge pipe 11 is installed at the top of the discharge port of the pump body 2. The discharge pipe 11 is connected to the conveying chamber. The motor 12 is installed on one side of the support base 1. The rotating shaft 9 is connected to the output end of the motor 12 through a belt drive mechanism.

[0021] like Figure 1 , Figure 2 , Figure 5 , Figure 7 As shown, the pump body 2, pump cover 3, front sleeve 51, and rear sleeve 52 are configured in a volute shape, which helps to improve the flow efficiency and pressure of the slurry.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the pump cover 3 is detachably connected to the pump body 2 by a plurality of circumferentially evenly distributed bolts and nuts; the feed pipe 8 is installed on the side of the pump cover 3 by a plurality of circumferentially evenly distributed bolts and nuts, and the discharge pipe 11 is installed on the top of the discharge port of the pump body 2 by a plurality of circumferentially evenly distributed bolts and nuts; the detachable connection method facilitates cleaning and maintenance operations, allowing operators to easily perform internal inspections and repairs, while the plurality of circumferentially evenly distributed bolts and nuts ensures a tight connection and stability between the various components.

[0023] Work process:

[0024] I. Preparation Phase Before Launch

[0025] First, ensure all components are installed correctly and tightly connected. Support base 1 provides a stable foundation for the entire slurry pump. Pump body 2, mounted securely on support base 1, must have a rear guard plate 4 sealed on the central mounting hole of pump body 2. The sealing effect of the rear guard plate 4 must be checked to prevent internal media leakage during operation. Pump cover 3, inlet pipe 8, and outlet pipe 11 are connected by multiple evenly distributed circumferential bolts and nuts. These bolts and nuts must be checked for tightness. Simultaneously, ensure there are no foreign objects blocking the inlet pipe 8 and outlet pipe 11 to prevent obstruction of subsequent material flow. Front sleeve 51 is mounted on pump cover 3, and rear sleeve 52 is mounted on pump body 2. They are sealed together and located at the pumping point. Inside the delivery chamber, check its sealing and installation stability. The outer circumference of the front guard plate 6 is connected to the front sleeve 51, and the end face is connected to the pump cover 3. Ensure that the connection is reliable. The connecting pipe 7 is installed in the center of the front guard plate 6. Check that the connection of the connecting pipe 7 is normal. The rotating shaft 9 is rotatably mounted on the support base 1 and extends through multiple components into the delivery chamber. Check that the installation of the rotating shaft 9 is accurate and that its rotation is unobstructed. The impeller 10 is mounted on the rotating shaft 9. Ensure that the impeller 10 is firmly installed and concentric with the rotating shaft 9. The rotating shaft 9 is connected to the output end of the motor 12 through a belt drive mechanism. Check that the belt tension is appropriate and that the motor 12 is securely installed.

[0026] II. Startup Process

[0027] The operator connects motor 12 to the power supply, and the output end of motor 12 begins to rotate. Since the rotating shaft 9 is connected to the output end of motor 12 via a belt drive mechanism, the power output by motor 12 is transmitted to the rotating shaft 9 via the belt, causing the rotating shaft 9 to begin rotating. The impeller 10 mounted on the rotating shaft 9 rotates at high speed along with the rotating shaft 9. Because the pump body 2, pump cover 3, front sleeve 51, and rear sleeve 52 are designed in a volute shape, centrifugal force is generated inside the conveying cavity formed between the pump body 2, rear sleeve 4, and pump cover 3 when the impeller 10 rotates. Under the action of centrifugal force, the solid material located at the inlet of the feed pipe 8... The liquid-liquid mixture is drawn into the feed pipe 8, which is installed on the pump cover 3 and connected to the conveying chamber. The drawn-in material enters the conveying chamber through the feed pipe 8. The material entering the conveying chamber is further mixed under the centrifugal force generated by the high-speed rotation of the impeller 10 and moves towards the discharge port of the pump body 2. During this process, the volute-shaped pump body 2, pump cover 3, front sleeve 51, and rear sleeve 52 help guide the flow direction of the medium. At the same time, the centrifugal force generated continuously increases the energy of the medium, enabling the solid-liquid mixture to be effectively pushed towards the discharge port. When the solid-liquid mixture moves to the vicinity of the discharge port of the pump body 2, since the discharge pipe 11 is installed at the top of the discharge port of the pump body 2 and connected to the conveying chamber, the medium will be pressed into the discharge pipe 11 and discharged from the pump body 2 through the discharge pipe 11, completing the entire material conveying process.

[0028] III. Cleaning and Maintenance:

[0029] When internal cleaning is required, turn off motor 12 to stop the slurry pump. Loosen the fastening bolts between pump cover 3 and pump body 2, as well as the connecting bolts between feed pipe 8 and discharge pipe 11 and pump body 2. Remove components such as pump cover 3, front sleeve 51, and rear sleeve 52 to expose the internal impeller 10, conveying chamber, etc. You can directly clean the internal residues, remove dirt and impurities, and inspect and repair components such as impeller 10, sleeve 5, rear guard plate 4, and front guard plate 6. Replace any damaged or worn components promptly. After cleaning and repair, reinstall components such as pump cover 3, front sleeve 51, and rear sleeve 52, and tighten the bolts. Start motor 12 and perform a trial run to ensure the slurry pump is working properly.

[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
