Description

Technical Field

[0001] The utility model relates to the technical field of sand suction pumps, in particular to a sand suction pump impeller with a stirring function. Background Art

[0002] A sand suction pump is a type of sand pump, which is mostly used in sand ships to suck sand in rivers. After searching, the Chinese patent publication number CN203516180U discloses an impeller for a sand suction pump. Although the impeller has a simple structure and a reasonable design, by inflating the air flow channel from the air inlet, the gas is ejected from different air outlets respectively, which has a certain impact force on the crushed sand and gravel in the sand suction pump body, and can prevent the crushed sand and gravel from sticking to each other and preventing blockage. When the sand suction pump sucks some crushed sand and gravel with lower concentrations, the sand suction efficiency of the sand suction pump is generally higher; however, when sucking some crushed sand and gravel with higher concentrations, the crushed sand and gravel are relatively viscous, and the impeller blade structure is simple, and a good stirring effect cannot be achieved, which is prone to blockage, thereby easily affecting the efficiency of sand suction. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides a sand suction pump impeller with a stirring function, which solves the problem that the impeller of the existing sand suction pump proposed in the background technology is prone to clogging when sucking crushed sand and gravel with high viscosity.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a sand suction pump impeller with a stirring function, comprising an impeller body, a connecting rod, a telescopic rod and a roller, a rotating shaft inserted into the interior of the impeller body, an outer wall of one end of the bottom of the rotating shaft is welded to the impeller, the impeller is welded to one end of the connecting rod, a telescopic rod is provided at the other end of the connecting rod, one end of the telescopic rod is inserted into the interior of the connecting shaft, the connecting shaft is rotatably connected to the auxiliary impeller, two auxiliary impellers are provided at one end of the connecting shaft, the two auxiliary impellers are distributed up and down, and a roller is provided between the two auxiliary impellers, and the surface of the roller is welded to the auxiliary impeller.

[0005] Preferably, the impeller body is composed of a plurality of blades regularly distributed in a circular shape with equal spacing, and the surface of the blades on the surface of the impeller body is curved, so that a better stirring effect can be achieved through the curved impeller.

[0006] Preferably, the interior of one end of the connecting rod is hollow, and a telescopic rod is inserted into the interior of one end of the connecting rod. The outer wall of one end of the telescopic rod is in sliding contact with the inner wall of the connecting rod. The connecting rods are provided in five groups, each group is provided with two connecting rods distributed up and down, and each group of connecting rods corresponds to two auxiliary impellers. By providing two telescopic rods above and below the roller, it is helpful to prevent the roller from rotating vertically while rotating around the rotating axis.

[0007] Preferably, a limiting ring is welded to the outer wall of the connecting rod, and a spring is provided on one side of the limiting ring. The spring is sleeved on the outside of the connecting rod and the telescopic rod, so that the roller can always fit with the inner wall of the sand suction pump under the action of the spring.

[0008] Preferably, the roller surface is provided with holes and grooves, and the roller diameter is larger than the auxiliary impeller diameter. The outer wall surface of the roller is provided with a rubber coating. The rubber coating is conducive to increasing the friction between the roller and the inner wall of the sand suction pump, thereby helping the roller to maintain stable rotation.

[0009] The utility model provides a sand suction pump impeller with a stirring function. It has the following beneficial effects:

[0010] (1) A sand suction pump impeller with a stirring function. When the impeller is in use, the sand suction pump drives the impeller body to rotate through the rotating shaft. While the impeller body rotates, it can drive the roller to rotate around the rotating shaft through the connecting rod. While the roller rotates around the rotating shaft, it can contact the inner wall of the sand suction pump, so that the roller can rotate on its own. While the roller rotates on its own, it can drive the upper and lower auxiliary impellers to rotate, so that the auxiliary impellers can rotate on their own while rotating around the rotating shaft, which is beneficial to increase the disturbance of crushed sand and gravel, thereby playing a certain stirring function, preventing the crushed sand and gravel from sticking to each other, thereby avoiding blockage and improving the sand suction efficiency. At the same time, the stirring function helps to impact the deposited sand and gravel into high-concentration turbulence, so that the water pump can achieve high-concentration silt suction without the need for auxiliary devices, thereby improving the sand suction efficiency of the sand suction pump.

[0011] (2) The impeller of the sand suction pump with a stirring function, when the auxiliary impeller rotates, one end of the spring can push the connecting shaft to move toward the inner wall of the sand suction pump, thereby enabling the telescopic rod to be extended and retracted inside the connecting rod. When the telescopic rod is extended and retracted outward inside the connecting rod, it can drive the roller to move toward the inner wall of the sand suction pump, and the roller can always fit with the inner wall of the sand suction pump, so that the roller can rotate on its own while the impeller body rotates, thereby avoiding wear of the inner wall of the sand suction pump and the generation of a gap between the roller and the roller.

[0012] Thus, the problem that the impeller of the existing sand suction pump is easily blocked when sucking crushed sand and gravel with high viscosity is solved. BRIEF DESCRIPTION OF THE DRAWINGS

The impeller body 1 is composed of a plurality of blades distributed in a regular annular shape with equal spacing, and the surface of the blades on the surface of the impeller body 1 is curved. When the impeller is in use, the sand suction pump passes through The rotating shaft 2 drives the impeller body 1 to rotate. When the impeller body 1 rotates, it can drive the roller 7 to rotate around the rotating shaft 2 through the connecting rod 3. When the roller 7 rotates around the rotating shaft 2, it can contact the inner wall of the sand suction pump, so that the roller 7 can rotate on its own. When the roller 7 rotates on its own, it can drive the upper and lower auxiliary impellers 6 to rotate, so that the auxiliary impeller 6 can rotate on its own while rotating around the rotating shaft 2, which is beneficial to increase the disturbance of the crushed sand and gravel, thereby playing a certain stirring function, preventing the crushed sand and gravel from sticking to each other, thereby avoiding blockage and improving the sand suction efficiency.

[0022] Working principle: First, the sand suction pump drives the impeller body 1 to rotate through the rotating shaft 2. While the impeller body 1 rotates, it drives the roller 7 to rotate around the rotating shaft 2 through the connecting rod 3. This rotation makes the roller 7 contact with the inner wall of the sand suction pump, thereby realizing the self-rotation of the roller 7. The self-rotation of the roller 7 further drives the upper and lower auxiliary impellers 6 to rotate. These auxiliary impellers 6 will also rotate while rotating around the rotating shaft 2. This self-rotation and rotation around the rotating shaft 2 help to increase the disturbance of crushed sand and gravel, realize the stirring function, prevent the crushed sand and gravel from sticking, avoid clogging, thereby improving the sand suction efficiency. The stirring function can also impact the deposited sand and gravel The high-concentration turbulence is formed, so that the sand suction pump can achieve high-concentration silt suction without auxiliary devices, further improving the sand suction efficiency. At the same time, the rotation of the auxiliary impeller 6 can also push the connecting shaft 5 to move toward the inner wall of the sand suction pump through the spring 9, so that the telescopic rod 4 can be retracted inside the connecting rod 3. When the telescopic rod 4 is retracted outward, it will drive the roller 7 to move toward the inner wall of the sand suction pump, ensuring that the roller 7 is always in contact with the inner wall. In this way, even when the impeller body 1 rotates, the roller 7 can keep rotating, avoiding the generation of a gap between the inner wall of the sand suction pump and the roller 7 due to wear. This design helps to reduce wear and extend the service life of the equipment.
