Description

Technical Field

[0001] The invention belongs to the technical field of slurry pumps, in particular to a shock-absorbing slurry pump. Background Art

[0002] The Chinese patent with the publication number CN113236571A discloses a shock-absorbing slurry pump, including a pump body, a fixed platform and a shock-absorbing assembly. The pump body includes a motor, an extension pipe, a pump casing and a water outlet pipe. A rotating shaft is installed in the extension pipe, and the bottom of the extension pipe is fixedly connected to the pump casing. The motor drives the impeller in the pump casing to rotate through the rotating shaft, and the water outlet pipe is connected to the pump casing; the fixed platform includes a bottom plate, a support plate and a support column connecting the bottom plate and the support plate; the shock-absorbing assembly is installed on the support column, and the shock-absorbing assembly includes a transverse elastic member and a damping buffer, one end of the transverse elastic member is hinged on the support column, and the other end abuts the extension pipe; the support head of the damping buffer is hinged on the transverse elastic member at an angle, and its bottom is hinged on the bottom plate. When the extension pipe vibrates radially, the transverse elastic member is squeezed in the horizontal direction; when the extension pipe vibrates axially, the transverse elastic member is driven to rotate downward and press the damping buffer downward, thereby improving the shock-absorbing performance of the slurry pump from multiple dimensions. However, the device has defects when in use. Slurry pumps are generally used to transport mud, and some larger particles (such as larger stones) may be mixed in the mud. The filter cover on the existing slurry pump generally has a strip-shaped groove for the mud to enter, and the filter cover lacks a cleaning mechanism, which causes the particles to be easily stuck in the groove during use of the device, causing the filter cover to be blocked, affecting the entry of mud. At the same time, if the particles enter the pump body under the impact of the mud, this will damage the impeller. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figure 1-6 As shown, the present application provides a shock-absorbing slurry pump, comprising a fixed platform 1 and a pump body 2 arranged on the fixed platform 1, and an impeller 3 arranged in the pump body 2, a filter cover 4 is arranged at the bottom of the pump body 2, a through groove 5 is penetrated through the outer surface of the filter cover 4, and a cleaning mechanism 6 for cleaning the through groove 5 is arranged in the filter cover 4; the cleaning mechanism 6 comprises a fixed shaft 61 fixedly connected to the inside of the filter cover 4 and a push plate 62 rotatably connected to the through groove 5 through a rotating shaft, the push plate 62 is used to clean the through groove 5, the top end of the fixed shaft 61 is fixedly connected to a support body 63, a cavity 64 is opened in the interior of the support body 63, and a support body 63 is movably connected to cooperate with the push plate 62 An ejector rod 65 is used, and an ejector mechanism 66 for driving the ejector rod 65 to move is arranged between the support body 63 and the impeller 3. A first spring 67 is fixedly connected to the push plate 62, and the first spring 67 is fixedly connected to the filter cover 4. The impeller 3 will drive the connecting arm 661 to rotate, and then drive the cam 663 to rotate through the connecting shaft 662. During the rotation of the cam 663, the cam 663 contacts the roller 10, thereby pushing the ejector rod 65, and then the ejector rod 65 moves out of the cavity 64, and then the ejector rod 65 will push the push plate 62, so that the push plate 62 moves toward the through groove 5 as a whole. When the push plate 62 moves into the through groove 5 as a whole, the particles stuck in the through groove 5 can be pushed out, thereby cleaning the through groove 5. The impeller 3 is used to drive the ejection mechanism 66 to rotate, so that the ejection rods 65 move outward one by one, thereby causing the push plates 62 to swing one by one. During the swinging process, the particles in the through groove 5 can be pushed out to clean the through groove 5. The push plates 62 can be reset after cleaning the through groove 5, and will not affect the mud transportation.

[0033] The ejection mechanism 66 includes a connecting arm 661 detachably connected to the bottom of the impeller 3, and a connecting shaft 662 is fixedly connected to the connecting arm 661. One end of the connecting shaft 662 passes through the support body 63 and extends into the cavity 64. A cam 663 is fixedly connected to the connecting shaft 662 for driving the ejection rod 65 to move. The cam 663 cooperates with each ejection rod 65 one by one, so that adjacent ejection rods 65 move out of the cavity 64 in turn, so that each through groove 5 is cleaned in turn, and the push plate 62 can be reset after cleaning the through groove 5, which will not affect the mud transportation.

[0034] The support body 63 is externally fixedly connected with a cylinder 7 , and the cylinder 7 is slidably connected with an ejection rod 65 . One end of the ejection rod 65 is attached to the push plate 62 , and a reset mechanism 8 is provided between the cylinder 7 and the ejection rod 65 .

[0035] The reset mechanism 8 includes a rubber plate 81 fixedly connected to the ejector rod 65 and a second spring 82 sleeved on the ejector rod 65. The two ends of the second spring 82 are respectively fixedly connected between the rubber plate 81 and the cylinder 7. When the ejector rod 65 moves out of the cavity 64, the rubber plate 81 moves along with the ejector rod 65, so that the rubber plate 81 compresses the second spring 82. When the cam 663 gradually moves away from the ejector rod 65, the compressed second spring 82 gradually recovers, and then drives the ejector rod 65 to recover through the rubber plate 81.

[0036] One end of the ejector rod 65 is arranged in an arc shape, and the other end of the ejector rod 65 is provided with a mounting groove 9 , in which a roller 10 used in conjunction with the cam 663 is arranged.

[0037] Embodiment 2

[0038] Based on Example 1, see Figure 2 , Figure 4 and Figure 6 shown.

[0039] The filter cover 4 is fixedly connected with an inclined rod 11, which is an elastic support. One end of the inclined rod 11 is set in an arc shape. The inclined rod 11 is used to limit the push plate 62. When the push plate 62 moves toward the middle 5, the first spring 67 will gradually be stretched by force. When the ejection rod 65 gradually moves away from the push plate 62, the push plate 62 loses the support of the ejection rod 65, and then the stretched first spring 67 will gradually recover, and then drive the push plate 62 to recover. After the push plate 62 recovers, the push plate 62 will be placed on the inclined rod 11. The inclined rod 11 is used to limit the push plate 62, which can prevent the push plate 62 from colliding with the cylinder 7. By providing the inclined rod 11, when the push plate 62 resets after cleaning the through groove 5, the inclined rod 11 is used to limit the push plate 62, which can prevent the push plate 62 from colliding with the cylinder 7.

[0040] Embodiment 3

[0041] Based on Example 1, see Figure 1 and Figure 5 shown.

[0042] A reinforcement rod 12 is fixedly connected to the bottom of the fixed platform 1 . There are three reinforcement rods 12 . A connecting plate 13 is fixedly connected between the bottom ends of the three reinforcement rods 12 . A reinforcement mechanism 14 is provided between the reinforcement rod 12 and the pump body 2 .

[0043] The reinforcement mechanism 14 includes a first ring body 141 rotatably connected to the reinforcement rod 12 and a second ring body 145 rotatably connected to the pump body 2, the first ring body 141 is fixedly connected to a first connecting rod 142, one end of the first connecting rod 142 is provided with a movable groove 143, a third spring 144 is fixedly connected in the movable groove 143, the second ring body 145 is fixedly connected to a second connecting rod 146, the second connecting rod 146 is slidably connected to the movable groove 143, and the second connecting rod 146 is fixedly connected to the third spring 144. When the slurry pump is working, the high-speed rotation of the impeller at the bottom of the slurry pump causes high-frequency vibration and swing of the housing part where the main shaft of the slurry pump is located. When vibration and swing occur, the second connecting rod 146 slides in the movable groove 143 and the third spring 144 is used to buffer the second connecting rod 146, thereby reducing vibration and swing, achieving shock absorption of the housing part where the main shaft of the slurry pump is located, and preventing the high-speed rotation of the impeller at the bottom of the slurry pump from causing high-frequency vibration and swing of the housing part where the main shaft of the slurry pump is located. By providing the reinforcement mechanism 14, the reinforcement mechanism 14 is used to reduce vibration of the casing where the main shaft of the slurry pump is located, thereby preventing the high-speed rotation of the impeller at the bottom of the slurry pump from causing high-frequency vibration and swing of the casing where the main shaft of the slurry pump is located.

[0044] Working principle of the present invention: When the vertical slurry pump is working, the impeller 3 drives the connecting arm 661 to rotate, and then drives the cam 663 to rotate through the connecting shaft 662. During the rotation of the cam 663, the cam 663 contacts the roller 10, thereby pushing the ejector rod 65, and then the ejector rod 65 moves out of the cavity 64, and then the ejector rod 65 pushes the push plate 62, so that the push plate 62 moves toward the through groove 5 as a whole. When the push plate 62 moves into the through groove 5 as a whole, the particles stuck in the through groove 5 can be pushed out, so as to clean the through groove 5. In the process of the ejector rod 65 moving out of the cavity 64, the rubber plate 81 moves with the ejector rod 65, so that the rubber plate 81 compresses the second spring 82. When the cam 663 gradually moves away from the ejector rod 65, the compressed second spring 82 gradually recovers, and then drives the ejector rod 65 to recover through the rubber plate 81. During the movement of the push plate 62 toward the cavity 5, the first spring 67 will be gradually stretched by force. When the ejector rod 65 gradually moves away from the push plate 62, the push plate 62 loses the support of the ejector rod 65, and the stretched first spring 67 will gradually recover, and then drive the push plate 62 to recover. After the push plate 62 recovers, the push plate 62 will be placed on the inclined rod 11, and the inclined rod 11 is used to limit the push plate 62, so that the push plate 62 can be prevented from colliding with the cylinder 7. The cam 663 will cooperate with each ejector rod 65 one by one, so that the adjacent ejector rods 65 move out of the cavity 64 in turn, so that each through groove 5 can be cleaned in turn, and the push plate 62 can be reset after cleaning the through groove 5, which will not affect the mud transportation. When the slurry pump is working, the impeller at the bottom of the slurry pump rotates at a high speed, causing high-frequency vibration and swing in the shell part where the main shaft of the slurry pump is located. When vibration and swing occur, the second connecting rod 146 slides in the movable groove 143 and the third spring 144 is used to buffer the second connecting rod 146, thereby reducing vibration and swing, achieving shock absorption of the shell part where the main shaft of the slurry pump is located, and preventing the high-speed rotation of the impeller at the bottom of the slurry pump from causing high-frequency vibration and swing in the shell part where the main shaft of the slurry pump is located.

[0045] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. 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.
