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] Chinese patent publication number CN113236571A discloses a shock-absorbing slurry pump, comprising a pump body, a fixed platform, and a shock-absorbing assembly. The pump body includes a motor, an extension tube, a pump casing, and a water outlet pipe. A rotating shaft is mounted within the extension tube, the bottom of which is fixedly connected to the pump casing. The motor drives the impeller within the pump casing via the rotating shaft, and the water outlet pipe is connected to the pump casing. The fixed platform includes a base plate, a support plate, and a support column connecting the base plate and the support plate. The shock-absorbing assembly is mounted on the support column and includes a transverse elastic member and a damping buffer. One end of the transverse elastic member is hinged to the support column, and the other end abuts the extension tube. The head of the damping buffer is hinged obliquely to the transverse elastic member, and its bottom is hinged to the base plate. When the extension tube vibrates radially, it compresses the transverse elastic member horizontally. When the extension tube vibrates axially, it drives the transverse elastic member to rotate downward, pressing down on the damping buffer, thereby improving the shock-absorbing performance of the slurry pump in multiple ways. However, this device has defects when in use. Slurry pumps are generally used to transport mud, and some larger particles (such as larger stones) are mixed in the mud. The filter cover on the existing slurry pump generally has a strip-shaped trough for the mud to enter, and the filter cover lacks a cleaning mechanism. As a result, during the use of the device, particles are easily stuck in the trough, causing the filter cover to be blocked, affecting the entry of mud. At the same time, if particles enter the pump body under the impact of the mud, this will damage the impeller. Summary of the Invention

DETAILED DESCRIPTION

[0030] The technical solutions of the present application will be described clearly and completely below in connection with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. 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 the present application.

[0031] Embodiment one

[0032] Please refer to Figure 1-6 As shown in the figure, the present application provides a shock-absorbing type slurry pump, which comprises a fixed platform 1, a pump body 2 arranged on the fixed platform 1, and an impeller 3 arranged in the pump body 2. The bottom of the pump body 2 is provided with a filter cover 4. The outer surface of the filter cover 4 is provided with a through slot 5. The filter cover 4 is provided with a cleaning mechanism 6 for cleaning the through slot 5. The cleaning mechanism 6 comprises a fixed shaft 61 fixedly connected inside the filter cover 4 and a push plate 62 rotatably connected in the through slot 5 through a rotating shaft. The push plate 62 is used for cleaning the through slot 5. The top end of the fixed shaft 61 is fixedly connected with a support body 63. The inside of the support body 63 is provided with a cavity 64. The support body 63 is movably connected with an ejection rod 65 used in cooperation with the push plate 62. The support body 63 and the impeller 3 are provided with an ejection mechanism 66 for driving the ejection rod 65 to move. The push plate 62 is fixedly connected with a first spring 67. The first spring 67 is fixedly connected between the filter cover 4. The impeller 3 drives the connecting arm 661 to rotate, and then drives the cam 663 to rotate through the connecting shaft 662. In the process of rotating the cam 663, the cam 663 contacts with the roller 10, so as to push the ejection rod 65, and then the ejection rod 65 moves outwardly to the cavity 64, and then the ejection rod 65 pushes the push plate 62, so that the push plate 62 moves as a whole to the through slot 5, so as to push the particles stuck in the through slot 5, and realize the cleaning of the through slot 5. The impeller 3 drives the ejection mechanism 66 to rotate, so that the ejection rod 65 moves outward one by one, so that the push plate 62 swings one by one. In the process of swinging, the particles in the through slot 5 can be pushed out, and the through slot 5 can be cleaned. After the push plate 62 cleans the through slot 5, it can be reset, and it will not affect the slurry conveying.

[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 will cooperate 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 will 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.

[0034] The support body 63 is fixedly connected to the outside with a cylinder 7 , and the cylinder 7 is slidably connected to the 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 ejection rod 65 and a second spring 82 sleeved on the ejection 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 ejection rod 65 moves out of the cavity 64, the rubber plate 81 moves along with the ejection rod 65, so that the rubber plate 81 compresses the second spring 82. When the cam 663 gradually moves away from the ejection rod 65, the compressed second spring 82 gradually recovers, and then drives the ejection rod 65 to recover through the rubber plate 81.

[0036] One end of the ejection rod 65 is configured to be arc-shaped, and the other end of the ejection rod 65 is provided with a mounting groove 9 , in which a roller 10 used in conjunction with the cam 663 is provided.

[0037] Example 2

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

[0039] The filter cover 4 is fixedly connected to 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. During the movement of the push plate 62 toward the center 5, the first spring 67 is gradually stretched by the force. When the ejection rod 65 gradually moves away from the push plate 62, the push plate 62 loses the support function of the ejection rod 65, and the stretched first spring 67 gradually recovers, thereby driving the push plate 62 to recover. After the push plate 62 recovers, the push plate 62 rests on the inclined rod 11. The inclined rod 11 is used to limit and support the push plate 62, thereby preventing the push plate 62 from colliding with the cylinder 7. By providing the inclined rod 11, when the push plate 62 returns to its original position after cleaning the through groove 5, the inclined rod 11 is used to limit and support the push plate 62, thereby preventing the push plate 62 from colliding with the cylinder 7.

[0040] Example 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 rods 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, the movable groove 143 is fixedly connected to a third spring 144, 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 impeller at the bottom of the slurry pump rotates at a high speed, causing the casing where the main shaft of the slurry pump is located to vibrate and swing at a high frequency. 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, thereby achieving shock absorption of the casing 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 casing 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 housing 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 housing where the main shaft of the slurry pump is located.

[0044] The working principle of the present invention is as follows: When the vertical slurry pump is in operation, the impeller 3 drives the connecting arm 661 to rotate, which in turn drives the cam 663 to rotate via the connecting shaft 662. During the rotation of the cam 663, the cam 663 contacts the roller 10, thereby pushing the ejector rod 65, which in turn moves the ejector rod 65 out of the cavity 64. The ejector rod 65 then pushes the push plate 62, causing the push plate 62 to move as a whole toward the through slot 5. When the push plate 62 moves as a whole into the through slot 5, it can push out particles stuck in the through slot 5, thereby cleaning the through slot 5. During the movement of the ejector rod 65 out of the cavity 64, the rubber plate 81 moves along with the ejector rod 65, thereby compressing 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 center 5, the first spring 67 is gradually stretched by the 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 gradually recovers, thereby driving the push plate 62 to recover. After the push plate 62 recovers, the push plate 62 rests on the inclined rod 11, and the inclined rod 11 is used to limit and support the push plate 62, thereby preventing the push plate 62 from colliding with the cylinder 7. The cam 663 cooperates 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 is cleaned in turn, and the push plate 62 can be reset after cleaning the through groove 5, without affecting the mud transportation. When the slurry pump is working, the impeller at the bottom of the slurry pump rotates at a high speed, causing the shell part where the main shaft of the slurry pump is located to vibrate and swing at a high frequency. 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 of 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 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.
