Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pumps, in particular to an easily detachable front guard plate for a slurry pump. Background Art

[0002] The slurry pump belongs to the centrifugal pump in terms of its working principle. It is a device that converts electrical energy into kinetic energy and potential energy of the medium. It transports solid-liquid mixed media through the action of centrifugal force. It is used in many industries such as metallurgy, coal, electricity, chemical industry, building materials, and mining production. It can also be used for sewage discharge and river transportation. It has a wide range of uses. The pump head structure of the slurry pump consists of an impeller, a front guard plate body, a rear guard plate body, and a sheath. The front guard plate body and the rear guard plate body are fixedly connected. The impeller and the sheath are located inside the front guard plate body and the rear guard plate body. The front guard plate body, the rear guard plate body and the sheath cooperate to form a semi-closed flow channel, so that the slurry runs in this space;

[0003] The front guard plate body and the rear guard plate body on the slurry pump body on the market are often fixed and connected by bolts. When removing them, the staff needs to use a wrench to unscrew all the fixing nuts to release the limit of the front guard plate and the rear guard plate, so as to separate the two and complete the disassembly. However, this disassembly is time-consuming and laborious, and it is difficult to disassemble without a corresponding disassembly wrench, which increases the difficulty of disassembly and reduces the convenience of later maintenance and replacement of the front guard plate. For this reason, we propose an easily disassembled front guard plate for a slurry pump. Utility Model Content

[0009] Preferably, one end of the extension rod is fixedly connected to a threaded connecting rod, and the inner cavity of one end of the sleeve is provided with a threaded connecting hole matched with the threaded connecting rod.

[0010] Preferably, a bracket is fixedly connected to the bottom of the rear guard plate body.

[0011] Preferably, a rubber protective sleeve is provided on the surface of the hand-held rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a connecting ring, a positioning assembly and a hand-held rod. When the front guard plate body and the rear guard plate body are connected, the limit plate arranged on the edge of the front guard plate body is fitted to the surface of the threaded connecting pipe arranged on the edge of the rear guard plate body, and the two can be quickly and accurately fitted together by means of the engagement between the positioning block and the positioning hole. At the same time, the connecting ring is sleeved on the surface of the front guard plate body and the inner side of the clamping convex edge arranged in the inner cavity is abutted against the outer side wall of the limiting plate, so that the connecting ring is sleeved at the fitting position of the two, and the connecting ring is rotated clockwise by the hand-held rod so that the connecting ring and the threaded connecting pipe on the rear guard plate are threadedly connected together, and with the movement of the connecting ring, the front guard plate body and the rear guard plate body are tightly fitted together, so that the two are quickly fixed together, and the reverse operation can quickly separate the two, so that the front guard plate can be quickly disassembled, and there is no need to use a disassembly wrench for disassembly, which saves time and effort, reduces the difficulty of disassembly of the front guard plate, and improves the convenience of later maintenance.

[0014] 2. The utility model uses a carrying rod, and when disassembling and assembling, the connecting sleeve is conveniently rotated with the help of the carrying rod, thereby facilitating disassembly and assembly. When using the carrying rod, pinch the sleeve and rotate the extension rod counterclockwise, so that the extension rod drives the threaded connecting rod fixed at the top to move backward along the threaded connecting hole, and then the extension rod moves backward, so as to adjust the length of the carrying rod, thereby facilitating the use of different personnel, and the sleeve is threadedly connected to the fixing screw holes on both sides of the connecting sleeve through the threaded connecting head, thereby facilitating disassembly and assembly, and can be replaced in time when damaged, effectively reducing the difficulty of later disassembly and assembly of the front guard plate body, and further improving the convenience of later maintenance or replacement.
