Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slurry pump applications, and particularly relates to a slurry pump with intermittently rotatable front guard plates. BACKGROUND

[0002] A slurry pump is a device used to transport high-concentration, high-viscosity, and particle-containing liquids. It is commonly used in industries such as mining, construction sites, and chemical plants. A slurry pump typically consists of a pump body, an impeller, a bearing device, and a sealing device. The working principle of a slurry pump is to generate centrifugal force through the rotation of the impeller to suck in liquid and discharge it through the pump body. The blades on the impeller can effectively push high-concentration slurry to flow and handle media containing particles. A slurry pump can transport high-concentration slurry and effectively handle even larger solid particles. A slurry pump is usually made of wear-resistant materials to withstand corrosive media containing particles, thereby extending the service life of the pump. A slurry pump has stable working performance and can maintain efficient transportation during long-term continuous operation.

[0003] However, the existing slurry pump often encounters the following problems during use:

[0004] (1) The front guard plate of the slurry pump plays a flow guiding role during transportation, but since the front guard plate is generally fixed and cannot move, the flow direction of the slurry in the pump will cause severe wear on part of the plate surface of the front guard plate. To address this issue, workers usually disassemble the pump body and rotate the front guard plate to the less-worn part of the plate surface to ensure long-term use of the front guard plate. However, this adjustment process is too cumbersome and time-consuming.

[0005] (2) Due to the high viscosity of the slurry, clumping and blockage can occur once the slurry converges. SUMMARY

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0065] like Figures 1-8 As shown, a slurry pump with an intermittently rotating front guard plate includes: a base 1, a drive motor 2, a power shaft 3, a transmission shaft 4, a coupling 5, a pump housing 6, a pump shaft assembly 7, an impeller 8, a transmission rod 9, and an intermittent rotation mechanism 10. The base 1 is erected on the ground, the drive motor 2 is mounted on the base 1, the power shaft 3 is mounted on the output end of the drive motor 2, and the transmission shaft 4 is located in the extension direction of the output end of the drive motor 2. One end of the coupling 5 is connected to the power shaft 3, and the other end of the coupling 5 is connected to the transmission shaft 4. The arrangement of the coupling 5 can effectively extend the transmission distance of the power shaft 3, thereby reducing losses when power is transmitted to the transmission shaft 4 and preventing speed reduction. One end of the transmission shaft 4 is inserted into the pump housing 6, the pump shaft assembly 7 is sleeved on one end of the transmission shaft 4, the impeller 8 is sleeved on the transmission shaft 4, one end of the transmission rod 9 is fixedly connected to the pump shaft assembly 7, and the intermittent rotation mechanism 10 is mounted on the other end of the transmission rod 9.

[0066] In this embodiment, Figure 2As shown, in order to reduce the replacement or adjustment of the front guard 11 to the slag pump disassembly work, the pump housing 6 is designed, including, the transmission shaft 4 one end of the rear cover 61, the connecting ring shell 62 one end and the rear cover 61 through a set of bolts fixed connection, discharge pipe 63 longitudinal installation in the connecting ring shell 62 one side of the outer surface, arc front cover 64 located in the extension direction of the connecting ring shell 62 one side, the feed pipe 68 is installed on the arc front cover 64, annular groove 65 is arranged in the inner wall of the arc front cover 64, the open 66 is set in the upper half of the annular groove 65, because the front guard 11 embedded in the annular groove 65, so the top cover 67 is located in the top of the front guard 11, the side edge of the top cover 67 and the side of the open 66 hinge, once the front guard 11 needs to be replaced, only need to open the top cover 67, can directly take out the front guard 11, save the cumbersome disassembly steps, improve work efficiency.

[0067] In this embodiment, as shown in Figures 5-8 In order to make the front guard 11 intermittent rotation so that the plate surface is evenly rubbed by the slag, the intermittent rotation mechanism 10 is designed, including, the eccentric shaft 101 is fixedly arranged at the end of the transmission rod 9, the end of the eccentric shaft 101 abuts against the non-axle center of one side of the eccentric wheel 102, once the eccentric shaft 101 rotates, the centrifugal inertia generated thereby will also drive the eccentric wheel 102 to move, the first connecting rod 103 is installed above the wheel surface of the eccentric wheel 102, the first driving member 104 is longitudinally fixedly installed at the top end of the first connecting rod 103, the second connecting rod 105 is installed below the wheel surface of the eccentric wheel 102, the second connecting rod 105 is in the shape of a stepped bend, the second driving member 106 is installed at the bottom end of the second connecting rod 105, the limiting member 107 is located at the other side of the eccentric wheel 102, the bottom end of the limiting member 107 abuts against the other side of the wheel surface of the eccentric wheel 102, the clamping groove 108 is opened at the top of the limiting member 107, the eccentric wheel 102 is located inside the transmission wheel 109, and a plurality of hole grooves are opened in the side wall of the transmission wheel 109. The bottom of the bend of the second connecting rod 105 contacts the rim of the transmission wheel 109, when the eccentric wheel 102 moves, the eccentric wheel 102 which should originally rotate by a large amplitude cannot move by a large amplitude due to the rim resistance of the transmission wheel 109 on the bottom of the bend of the second connecting rod 105, so that the inertia power is converted into small amplitude rotation and downward movement of the eccentric wheel 102 by limiting the movement range of the first driving member 104 by the limiting member 107. The small amplitude rotation and downward movement of the eccentric wheel 102 represent the small amplitude rotation and downward movement of the first connecting rod 103 and the second connecting rod 105, and finally the small amplitude rotation of the first connecting rod 103 drives the small amplitude rotation and downward movement of the first driving member 104. The first driving member 104 and the second driving member 106 are both in the hole grooves of the side wall of the transmission wheel 109, and the first driving member 104 and the second driving member 106 are driven and replaced by inserting the hole grooves, so as to form the intermittent rotation of the transmission wheel 109, and the front guard 11 connected with the transmission wheel 109 is intermittently rotated.

[0068] Preferably, at least two movable rollers (not shown in the figure) are installed in the annular groove 65, the bottom of the front guard 11 contacts the side surface of the rollers, once the front guard 11 rotates, the rollers will assist the front guard 11 to roll to reduce the resistance of the front guard 11 rotation, reduce friction.

[0069] It should be noted that the present application designs a front guard intermittently rotating slurry pump, in use, the driving motor 2 is started, the motor output end rotates to drive the power shaft 3, the power shaft 3 drives the transmission shaft 4 through the shaft coupling 5, the transmission shaft 4 rotates to drive the impeller 8 to rotate to generate negative pressure, the negative pressure generates suction force, the slurry enters the pump housing 6 through the feed pipe 68, at the same time the transmission shaft 4 drives the transmission rod 9, the transmission rod 9 drives the intermittent rotating mechanism 10, the eccentric rotating shaft 101 is driven to rotate by the transmission rod 9, the eccentric rotating shaft 101 drives the eccentric wheel 102 to move, the eccentric wheel 102 drives the first connecting rod 103 and the second connecting rod 105 to move, the first connecting rod 103 drives the first driving part 104, the second connecting rod 105 drives the second driving part 106, but the bottom of the second connecting rod 105 bending part cannot be greatly moved due to the resistance of the along the edge of the transmission wheel 109, and the first driving part 104 can only move up and down due to the activity limitation of the limiting part 107, therefore the activity of the eccentric wheel 102 is limited to small rotation plus up and down movement, the first driving part 104 and the second driving part 106 will be driven to move and replace the hole slot insertion, forming the intermittent rotation of the transmission wheel 109, the transmission wheel 109 drives the front guard 11 connected thereto to intermittently rotate, in this way, the slurry sucked will enter the pump body from the interval between the two connecting parts 12 and be dispersed by the intermittent rotating mechanism 10 to make it not easy to converge, reducing the blockage.
