Description

Technical Field

[0001] The utility model belongs to the technical field of slurry pumps, in particular to a slurry pump bracket component with adjustable impeller position. Background Art

[0002] Slurry pumps are centrifugal pumps in terms of their working principle. Conceptually, they are a type of machine that increases the energy of a solid-liquid mixture by utilizing centrifugal force (the rotation of the pump's impeller), converting electrical energy into kinetic and potential energy. They are primarily used in industries such as mining, power plants, dredging, metallurgy, chemicals, building materials, and petroleum.

[0003] In the existing technology, when the slurry pump is operating normally, there is a gap between the impeller and the front guard plate. The inlet area is a low-pressure area. A small part of the slurry thrown out by the impeller flows back into the gap between the impeller and the front guard plate, causing wear of the front guard plate and mixed flow at the inlet, thereby reducing the head and efficiency of the pump. For this reason, we propose a slurry pump bracket assembly with adjustable impeller position. Utility Model Content

[0030] Example 2

[0031] Based on Example 1, please refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The rotating assembly includes an external threaded ring 202 fixed to the side of the inlet 108, the outer portion of the external threaded ring 202 is connected to an internal threaded ring 203 by a thread, and a filter 213 is fixedly provided on the inner wall of the internal threaded ring 203. The filter 213 can filter impurities in the liquid entering the pump body 102;

[0032] A threaded groove is provided inside the filter screen 213, and a screw cap is connected to the threaded groove through a thread. When the slurry pump is in normal use, the screw cap is screwed into the threaded groove in advance to prevent impurities from entering the pump body 102 through the threaded groove.

[0034] The utility model adopts the designed adjustment mechanism. When a large gap appears between the impeller body 106 and the front guard plate 104 during use, the rotating rod 205 is extended into the pump body 102 so that the cross-shaped head on the rotating rod 205 is aligned with the cross-shaped hole 214 and inserted into the corresponding cross-shaped hole 214 on the conical plate 206.

Subsequently, the bearing box 209 is moved toward the pump body 102, thereby driving the bearing ring on the right side of the annular tube 217 to move and tightly fix the impeller body 106, thereby adjusting the gap between the impeller body 106 and the front guard plate 104 as needed, thereby adjusting the position of the impeller body 106, reducing the wear on the front guard plate 104, and ensuring that the pump head and efficiency will not be affected by the gap between the impeller body 106 and the front guard plate 104.

[0035] Example 3

[0036] Based on Example 2, please refer to Figure 1 Two sets of strip brushes 204 are provided on the outside of the rotating rod 205, and an L-shaped plate 215 is fixedly provided on the side of the strip brush 204, and the L-shaped plate 215 is fixedly connected to the rotating rod 205 by screws.

[0037] The utility model combines the designed strip brush 204, L-shaped plate 215 and screws. When one end of the rotating rod 205 is extended from the threaded groove in the filter screen 213 into the interior of the pump body 102 to drive the impeller body 106 to rotate, the strip brush 204 on the rotating rod 205 can contact the surface of the filter screen 213. While rotating the rotating rod 205, the strip brush 204 can clean impurities attached to the surface of the filter screen 213, reducing the situation where impurities adhere to the surface of the filter screen 213 and affect the flow of liquid entering the pump body 102, making it convenient to use.

[0038] The working principle and use process of this utility model:

[0039] When the present invention is in use, when the gap between the impeller body 106 and the front guard plate 104 is large, first unscrew the screw cover tightened on the thread groove outward and remove it, then insert the end of the cross-shaped head at one end of the rotating rod 205 into the pump body 102 from the thread groove, then insert the end of the cross-shaped head into the cross-shaped hole 214 on the conical plate 206, then gently rotate the rotating rod 205, driving the cross-shaped head and the conical plate 206 to rotate, thereby driving the impeller body 106 to rotate to the right. At this time, the gap between the right side of the impeller body 106 and the front guard plate 104 is reduced. When it is rotated to the appropriate position, the impeller body 106 is stopped. At this time, the impeller body 106 starts to rotate on the spiral groove 219, and then the first bolt 200 is rotated outward to loosen it. , so that the stud 208 and the second bolt 210 are rotated to the right direction, at this time the working end of the stud 208 extends to the rightmost end of the upper hole, and pushes the bracket body 101 to the right direction, and then the working end of the second bolt 210 extends to the rightmost end of the lower hole, and pushes the bracket body 101 to the right, driving the mounting cover 216 to move through the bracket body 101, and the mounting cover 216 drives the annular tube 217 to move, and then the right side of the annular tube 217 pushes the bearing ring to move and makes the outer ring of the bearing ring contact and press against the impeller body 106, thereby fixing the impeller body 106, thereby reducing the gap between the impeller body 106 and the front guard plate 104. When it is necessary to increase the gap between the impeller body 106 and the front guard plate 104, the above-mentioned reverse principle can be used;

[0040] When the rotating rod 205 is rotated to drive the impeller body 106 to rotate, the two sets of strip brushes 204 on the rotating rod 205 will be driven to rotate, and then the strip brushes 204 will clean the impurities attached to the surface of the filter 213, reducing the adhesion of impurities on the surface of the filter 213. When the strip brushes 204 are worn out after being used for a long time, they can be replaced. When replacing, unscrew the screws on the L-shaped plate 215 and then remove the worn strip brush 204. Then take out the new strip brush 204 and follow the above-mentioned reverse principle to complete the replacement.

[0041] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
