Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slurry pump applications, particularly to a balanced slurry pump convenient to disassemble. BACKGROUND

[0002] A slurry pump is a type of pump used for transporting liquids containing solid particles, commonly used in mining, chemical industry, construction, and other fields. Slurry pumps typically have a large flow rate and head, capable of effectively transporting high-concentration solid particle suspensions. Slurry pumps play a crucial role in handling liquids containing solid particles, helping enterprises improve production efficiency and reduce costs.

[0003] Slurry pumps used in filter presses are usually used in filter press equipment to transport slurry containing solid particles generated by filter presses. During the filtration process, filter presses separate solid-liquid mixtures into solid and liquid parts, while filter press slurry pumps play a role in discharging slurry containing solid particles from filter presses and transporting them to the next processing stage. This type of pump usually needs to have high wear resistance and anti-clogging ability to cope with high solid particle content slurry.

[0004] However, the existing slurry pump often encounters the following problems in the use of filter presses:

[0005] (1) The existing slurry pump has a large axial force, which increases the load on the pump shaft and bearings, causing the bearings to wear out more quickly and reducing the service life of the pump. Excessive axial force also causes additional load on the pump blades, which can easily cause blade deformation, breakage, or wear, reducing pump efficiency.

[0006] (2) The pump housing of the slurry pump has a complex connection structure that requires multiple steps to disassemble. Without sufficient experience or disassembly tools, it is easy to encounter disassembly difficulties. Complicated disassembly steps make routine maintenance and maintenance very difficult. It is difficult to effectively clean and inspect internal components, which can easily cause equipment to run poorly or malfunction. SUMMARY

DETAILED DESCRIPTION

[0067] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0068] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "set", "connected", "connected" should be understood broadly, for example, to be fixedly connected, to be detachably connected, or integrally connected; to be mechanically connected, to be electrically connected; to be directly connected, to be indirectly connected through an intermediate medium, to be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application should be understood according to the specific circumstances.

[0069] As Figures 1-7As shown, a convenient disassembly balanced type slurry pump, comprising: base 1, motor 2, transmission shaft 3, transmission shaft 4, linkage shaft 5, rear pump shell 6, transmission rod 7, coaxial reversing mechanism 8, front pump shell 9, locking mechanism 10. The base 1 is erected on the ground, the motor 2 is erected above the base 1, the transmission shaft 3 is sleeved on the output end of the motor 2, the transmission shaft 4 is erected on one side of the output end of the motor 2, and the transmission shaft 3 is located inside the transmission shaft 4. Because the output end of the motor 2 is long and weak, the use of transmission shaft 4 can effectively ensure that the output end of the motor 2 will not be disturbed by external factors. The linkage shaft 5 is fixedly connected on one side of the transmission shaft 3, and one side of the rear pump shell 6 is sleeved on the linkage shaft 5. In this way, when the motor 2 starts, the rear pump shell 6 will not be affected by the motor 2 and will not rotate. One end of the transmission rod 7 is fixedly connected with the output end of the motor 2, the coaxial reversing mechanism 8 is installed on the other end of the transmission rod 7, the front pump shell 9 is arranged corresponding to the rear pump shell 6, and the locking mechanism 10 is arranged at the corresponding connection between the front pump shell 9 and the rear pump shell 6. The locking mechanism 10 has at least four around the connection between the front pump shell 9 and the rear pump shell 6, and the four locking mechanisms 10 can ensure the basic stability of the connection between the front pump shell 9 and the rear pump shell 6.
