Description

Technical Field

[0001] The present application relates to the field of fluid pumps, and in particular to a highly wear-resistant slurry pump with a cleaning function. Background Art

[0002] A slurry pump is a machine that increases the energy of a solid-liquid mixed medium by the action of centrifugal force, and converts electrical energy into the kinetic energy and potential energy of the medium. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller at high speed and entering the volute pump casing. In the volute pump casing, the liquid slows down due to the gradual expansion of the flow channel, and part of the kinetic energy is converted into static pressure energy, and finally flows into the discharge pipe at a higher pressure and is delivered to the required location. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Since the pressure above the liquid surface in the storage tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller.

[0003] Since the slurry pump is used to transport debris and mud, the debris and mud are easy to adhere to the impeller during use, resulting in a decrease in the conveying effect of the slurry pump. However, when the impeller of the existing slurry pump adheres to the debris and mud, resulting in a significant decrease in the conveying effect, it is necessary to pause the conveying of the slurry pump, open the pump casing and clean the impeller, and the whole cleaning process is relatively complicated.

[0009] Optionally, a gripping block is fixedly disposed on one end of the flexible mounting rod extending out of the pump housing, and the flexible mounting rod slides toward the inside of the pump housing to drive the gripping block to be inserted into the through hole to seal the through hole.

There are a plurality of blades, which are evenly distributed around the chassis. The inner ring and the outer ring are both mounted on the side of the blade away from the chassis. The inner ring and the outer ring are concentrically arranged, and the inner ring and the outer ring are respectively fixed at both ends of the blade in the length direction. The chassis is provided with an arc groove in the inner area of ​​the inner ring.

[0015] Optionally, the mounting soft rod includes a flexible metal inner core and an elastic rubber outer shell, and the rubber outer shell is coated on the outside of the flexible metal inner core.

[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. The blade grooves formed between the blades of the impeller are the main areas where debris and mud adhere. By installing a soft rod and extending the cleaning soft brush into the blade grooves of the impeller, the blade grooves of the impeller can be cleaned to reduce the probability of debris and mud adhering. The setting of the cleaning mechanism can clean the impeller without opening the pump casing, which facilitates the cleaning of the impeller; 2. The impeller can be disassembled to facilitate the replacement of damaged impellers, and the impeller can also be disassembled and cleaned. The chassis is provided with an arc groove in the inner area of ​​the inner ring. When the slag or mud enters the pump casing, the slag and mud will hit the chassis and then be diverted from the blade grooves between the blades. The impact of the slag and mud can easily cause damage to the chassis and even damage the motor. The opening of the arc groove can guide the slag or mud when it enters, thereby reducing the impact force of the slag or mud on the chassis, thereby reducing the probability of the impeller being damaged during use; 3. By pulling the soft rod outside the pump casing, the soft rod can be driven to slide on the sealing ring, thereby driving the soft brush to fold and separate from the impeller. When the impeller does not need to be cleaned, the influence of the cleaning mechanism on the rotation of the impeller is reduced; 4. The cleaning soft brush piece itself has the elasticity of rebound. When the force driving the installation soft rod to slide and fold the cleaning soft brush piece is removed, the installation soft rod is reset under the elastic force of the cleaning soft brush piece, so that the cleaning soft brush piece enters the groove between the blades. When cleaning the impeller, the impeller needs to be rotated. The rotation of the impeller will drive the installation soft rod to deform and thus escape from the groove between the blades. The elastic force of the cleaning soft brush piece can drive the installation soft rod to insert into the groove between the subsequent blades after the impeller rotates, so that the impeller can be cleaned when the impeller rotates at a low speed; 5. The anti-drop block and the pull-grip block enable the installation soft rod of the cleaning mechanism to seal the through hole in both states, thereby improving the sealing performance of the pump housing with the through hole; 6. The installation soft rod is connected through the slot on the card block, so there is no need to always grasp the pull handle to keep the cleaning soft brush away from the impeller, which is convenient for adjusting the state of the cleaning mechanism. At the same time, the elastic force of the cleaning soft brush can drive the installation soft rod. When the installation soft rod is connected to the slot, the elastic force of the cleaning soft brush can drive the pull handle to apply a force to the card block in the direction of the upper half shell, thereby improving the connection strength between the upper half shell and the lower half shell, reducing the probability of separation between the upper half shell and the lower half shell, and also improving the sealing effect between the upper half shell and the lower half shell.

[0024] The present application embodiment discloses a highly wear-resistant slurry pump with a cleaning function, referring to Figure 1 and Figure 3 , including a pump casing 1, the pump casing 1 includes an upper half shell 101 and a lower half shell 102, the upper half shell 101 and the lower half shell 102 are spliced ​​and fixed to each other by bolts to form the pump casing 1, the upper half shell 101 is provided with an inlet 2 on the side away from the lower half shell 102, and a flange is provided on the inlet 2, and the slag and mud in the pump casing 1 are transported through the flange connection pipeline, and the pump casing 1 is provided with an outlet 3 on the side wall, and the outlet 3 in this embodiment is an outlet 3 pipeline, half of the outlet 3 pipeline is integrally formed on the upper half shell 101 and the other half is integrally formed on the lower half shell 102, when the upper half shell 101 and the lower half shell 102 are spliced ​​and fixed to each other, the outlet 3 pipeline is also spliced ​​and fixed to form, and the outlet 3 pipeline is connected to the pipeline through the flange to discharge the slag and mud, and the connection of the pipeline can strengthen the connection between the upper half shell 101 and the lower half shell 102 Splicing, a rotating shaft 4 is rotatably provided on the side of the pump casing 1 away from the inlet 2, an impeller 7 is rotatably provided in the pump casing 1, the impeller 7 is mounted on the rotating shaft 4, the rotating shaft 4 is connected to the motor 5, and the impeller 7 is driven to rotate by the motor 5, a support frame 16 is provided between the motor 5 and the pump casing 1, the motor 5, the support frame 16 and the pump casing 1 are all mounted on a base 6, and are installed and fixed by the base 6, and the probability of displacement of the slurry pump during operation can be reduced by placing heavy objects on the base 6, the inlet 2 and the slag source or mud source to be conveyed are connected through a pipeline, the impeller 7 is driven to rotate by the motor 5, so that the slag or mud enters the pump casing 1 from the inlet 2 at the center of the impeller 7, and then leaves the pump casing 1 from the outlet 3 through the centrifugal force generated by the rotation of the impeller 7, and the slag or mud is guided to the area where the slag or mud is stored through the pipeline.

[0025] Reference Figure 2 and Figure 3The impeller 7 is detachably mounted on the rotating shaft 4. The impeller 7 can be disassembled to facilitate the replacement of a damaged impeller 7 or the repairable impeller 7 can be repaired. The impeller 7 can also be disassembled and cleaned, thereby achieving deep cleaning of the impeller 7. The impeller 7 includes a chassis 71, blades 72, an inner ring 73 and an outer ring 74. The chassis 71 is sleeved on the rotating shaft 4 and is detachably mounted on the rotating shaft 4 by bolts. There are several blades 72. The blades 72 are arc-shaped pieces. The blades 72 are arc-shaped pieces that can guide debris and mud, reduce the impact force of debris and mud on the blades 72, and increase the service life of the blades 72. Several blades 72 are evenly distributed around the chassis 71. The inner ring 73 and the outer ring 74 are both mounted on the side of the blade 72 away from the chassis 71. The inner ring 73 and the outer ring 74 are concentrically arranged. They are respectively fixed at both ends of the blade 72 in the length direction, and the chassis 71 is provided with an arc groove 15 in the inner area of ​​the inner ring 73. When debris or mud enters the pump casing 1, the debris and mud will hit the chassis 71 and then be diverted from the blade 72 grooves between the blades 72. The impact of the debris and mud can easily cause damage to the chassis 71 and even cause damage to the motor 5. The opening of the arc groove 15 can guide the debris or mud when it enters, thereby reducing the impact force of the debris or mud on the chassis 71, thereby reducing the probability of damage to the impeller 7 during use; the impeller 7 is made of high-chromium cast iron as a whole, and high-chromium cast iron has good wear resistance and corrosion resistance, which can reduce the friction loss of the impeller 7 during use, and can also reduce the degree of corrosion of the impeller 7 by corrosive debris or mud.

[0026] Reference Figure 1 , Figure 3 and Figure 4 A sealing ring 9 is arranged between the upper half shell 101 and the lower half shell 102. The sealing ring 9 is fixed to the upper half shell 101. The sealing ring 9 is made of rubber with elastic deformation ability. When the upper half shell 101 and the lower half shell 102 are spliced, the sealing ring 9 is clamped and compressed by the upper half shell 101 and the lower half shell 102. The sealing ring 9 is deformed due to compression to seal the gap between the upper half shell 101 and the lower half shell 102, thereby improving the overall sealing effect in the pump casing 1.

[0027] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6, a plurality of cleaning mechanisms 8 are arranged in the pump casing 1, and the cleaning mechanisms 8 are mounted on the sealing ring 9. In the present embodiment, four cleaning mechanisms 8 are arranged, and the four cleaning mechanisms 8 are evenly distributed around the pump casing 1. The cleaning mechanism 8 comprises a mounting soft rod 81 and a cleaning soft brush sheet 82. The mounting soft rod 81 is mounted on the pump casing 1 through the sealing ring 9, and the mounting soft rod 81 extends into the blade 72 groove of the impeller 7, and the cleaning soft brush sheet 82 is fixedly arranged on the mounting soft rod 81. The mounting soft rod 81 sends the cleaning soft brush sheet 82 into the blade 72 groove of the impeller 7, and the mounting soft rod 81 comprises a flexible metal inner core 811 and an elastic rubber jacket 812. The rubber jacket is coated on the outside of the flexible metal inner core 811, and the cleaning soft brush sheet 8 2 is a sheet body made of elastic rubber material, one end of the cleaning soft brush sheet 82 is integrally formed with the one end of the installation soft rod 81 inserted into the pump housing 1 and fixed on the elastic rubber jacket 812, and the other end of the cleaning soft brush sheet 82 is slidably arranged on the elastic rubber jacket 812, and one end of the cleaning soft brush sheet 82 slides against the sealing ring 9, and fine bristles are integrally formed on the edge of the sheet body. The flexible metal inner core 811 provides a certain degree of hardness for the installation soft rod 81, so that the installation soft rod 81 has a shaping ability, and the cleaning soft brush sheet 82 is sent into the gap between the blades 72 through the installation soft rod 81 to clean the debris and mud adhered to the gap between the blades 72, and the impeller in the pump housing 1 can be cleaned without opening the pump housing 1. 7 is cleaned to facilitate the cleaning of the impeller 7; the upper half shell 101 is provided with a through hole 10 corresponding to the installation position of the soft rod 81, the soft rod 81 is slidably installed on the sealing ring 9, one end of the soft rod 81 extends out of the through hole 10, and the cleaning soft brush piece 82 is installed in a wavy shape on the end of the soft rod 81 extending into the pump casing 1, and the cleaning soft brush piece 82 is made of elastic rubber material. The soft rod 81 is pulled toward the outside of the pump casing 1 to slide and drive the cleaning soft brush piece 82 to deform and fold. By pulling the soft rod 81 extending outside the pump casing 1, the soft rod 81 can be driven to slide on the sealing ring 9, thereby driving the cleaning soft brush piece 82 to fold and separate from the impeller 7. When the impeller 7 does not need to be cleaned, the cleaning mechanism is lowered. 8 has an impact on the rotation of the impeller 7. The cleaning soft brush sheet 82 itself has rebound elasticity. When the force driving the mounting soft rod 81 to slide and fold the cleaning soft brush sheet 82 is removed, the mounting soft rod 81 is reset under the elastic force of the cleaning soft brush sheet 82, thereby allowing the cleaning soft brush sheet 82 to enter the groove between the blades 72. When cleaning the impeller 7, the impeller 7 needs to be rotated. The rotation of the impeller 7 will drive the mounting soft rod 81 to deform and thus disengage from the groove between the blades 72. The elastic force of the cleaning soft brush sheet 82 can drive the mounting soft rod 81 to insert into the groove between the subsequent blades 72 after the impeller 7 rotates, thereby allowing the impeller 7 to be cleaned when the impeller 7 rotates at a low speed.

[0028] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6The end of the installation soft rod 81 extending out of the pump housing 1 is fixed with a gripping block 11. The gripping block 11 is a rubber block with a cross-sectional area larger than the cross-sectional area of ​​the installation soft rod 81. The gripping block 11 is integrally formed and fixed to the elastic rubber jacket 812. The gripping block 11 provides a gripping space for driving the sliding of the installation soft rod 81. The installation soft rod 81 slides toward the inside of the pump housing 1, driving the gripping block 11 to insert into the through hole 10 to seal the through hole 10. After the gripping block 11 is inserted into the through hole 10, the gripping block 11 extends out of the through hole 10 away from one end of the installation soft rod 81, thereby facilitating the gripping block 11 when pulling the installation soft rod 81. The installation soft rod 81 is located at one end of the pump housing 1. An anti-slip block 12 is fixedly arranged at the end, and the anti-slip block 12 is a rubber block with a cross-sectional area larger than that of the mounting soft rod 81. The anti-slip block 12 is integrally formed and fixedly arranged on the elastic rubber jacket 812. The mounting soft rod slides toward the outside of the pump casing 1, driving the anti-slip block 12 to abut against the sealing ring 9, and the sealing ring 9 deforms and seals the through hole 10. The provision of the anti-slip block 12 can reduce the probability of the mounting soft rod 81 being separated from the sealing ring 9 when the mounting soft rod 81 is driven to slide; the anti-slip block 12 and the gripping block 11 make the mounting soft rod 81 of the cleaning mechanism 8 seal the through hole 10 in both states, thereby improving the sealing of the pump casing 1 opened by the through hole 10.

[0029] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The lower half shell 102 is provided with a clamping block 13 corresponding to the installation soft rod 81, and a clamping groove 14 is opened on the clamping block 13. The cross-sectional area of ​​the clamping groove 14 is larger than the cross-sectional area of ​​the installation soft rod 81 and smaller than the cross-sectional area of ​​the pulling and holding block 11. The installation soft rod 81 is clamped by the clamping groove 14 on the clamping block 13, so that the cleaning soft brush sheet 82 can be kept away from the impeller 7 without always grasping the pulling and holding block 11, which is convenient for adjusting the state of the cleaning mechanism 8. At the same time, the elastic force of the cleaning soft brush sheet 82 can drive the installation soft rod 81. When the installation soft rod 81 is clamped in the clamping groove 14, the elastic force of the cleaning soft brush sheet 82 can drive the pulling and holding block 11 to apply a force to the clamping block 13 in the direction of the upper half shell 101, thereby improving the connection strength between the upper half shell 101 and the lower half shell 102, reducing the probability of the upper half shell 101 and the lower half shell 102 detaching, and also improving the sealing effect between the upper half shell 101 and the lower half shell 102.

[0030] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6The sealing ring 9 includes a mounting ring 91, a sealing ring 92 and a mounting block 93. The mounting ring 91 is embedded in the upper half shell 101. The sealing ring 92 is integrally formed and fixed on the mounting ring 91. There are several mounting blocks 93. In this embodiment, four mounting blocks 93 are arranged corresponding to the cleaning mechanism 8. The four mounting blocks 93 are evenly distributed around the mounting ring 91. The mounting block 93 is detachably mounted on the mounting ring 91 corresponding to the mounting soft rod 81. The mounting block 93 is an annular block with an I-shaped cross section. The mounting block 93 is connected to the mounting hole provided on the mounting ring 91 through deformation. When the cleaning soft brush sheet 82 is damaged, the corresponding cleaning mechanism 8 is disassembled by disassembling the mounting block 93, thereby facilitating the replacement of the cleaning mechanism 8 and reducing the cost of replacing a single cleaning mechanism 8 when it is damaged.

[0031] The implementation principle of the embodiment of the present application is as follows: the base 6 is placed on a flat ground and fixed by pressing with a heavy object, the pipeline is connected through a flange to connect the inlet 2 to the slag source or mud source to be conveyed, and the outlet 3 is connected to the area where the slag or mud needs to be delivered, the installation soft rod 81 is pulled to slide so that the installation soft rod 81 is engaged in the card slot 14 of the card block 13, so that the cleaning soft brush sheet 82 is folded away from the impeller 7, and then the motor 5 is started to drive the impeller 7 to rotate through the motor 5 to transport the slag or mud. When the slag or mud adheres to between the blades 72 of the impeller 7, the cleaning soft brush sheet 82 is folded away from the impeller 7. The motor 5 decelerates and drives the impeller 7 to rotate slowly, and at the same time drives the mounting soft rod 81 to disengage from the card slot 14. The mounting soft rod 81 slides under the elastic force of the cleaning soft brush piece 82, thereby driving the mounting soft rod 81 and the cleaning soft brush piece 82 to enter the groove between the blades 72 to clean the impeller 7. The impeller 7 rotates slowly to make the cleaning soft brush piece 82 clean the grooves between all the blades 72 in turn. After the cleaning is completed, the mounting soft rod 81 is driven by the grasping and pulling block 11 to slide and be clamped in the card slot 14 of the clamping block 13 again, and then the motor 5 is driven again to accelerate the transportation of slag or mud.
