Description

Technical Field

[0001] The invention relates to the technical field of end suction pumps, in particular to a horizontal end suction pump with a multi-stage filtering function which is easy to maintain. Background Art

[0002] An end-suction centrifugal pump, also known as an end-suction pump, is a centrifugal pump with a back-suction structure. When in use, the water is sucked in and rotates with the impeller through the rotation of the impeller. Due to the centrifugal force, the water is thrown to the outer edge of the impeller and flows into the water pressure pipeline of the water pump through the flow channel of the volute pump casing.

[0003] However, when the existing end-suction pump is repaired, the volute and the driving end need to be disassembled. After the disassembly is completed, a gas machine or manual handling is required to separate the volute and the driving end. In addition, it is very difficult to disassemble and replace parts of the end-suction pump. It can only be disassembled using limited tools such as crowbars and pullers, which requires a lot of manpower and material resources. Improper operation is prone to work-related injuries such as abrasions and smashing.

[0004] In order to prevent a large amount of impurities from entering the liquid, the existing end-suction pump will use a filter element and other equipment to filter the liquid. However, the liquid passing through the filter element will slowly enter the end-suction pump without increasing the power of the driving source, and the flow rate and pressure of the liquid discharged by the end-suction pump will be lower.

[0018] 2.

[0019] 3. Before the liquid enters the volute, the filter assembly can be used to filter the liquid preliminarily, and the filter assembly can be adjusted according to the needs, thereby changing the tightening degree of the elastic fiber line, thereby changing the state of the elastic fiber line when being impacted. When the elastic fiber line is straightened, it can block more particles, and when the elastic fiber line is relaxed, the elastic fiber line will become a net bag when it is impacted, and then the gap between the staggered elastic fiber lines will be expanded, thereby being able to block larger particles and release certain smaller particles or materials;

[0020] 4. When the impeller of the device rotates, with the cooperation of the magnetic assist component, the speed of the impeller can be increased without increasing the power of the driving motor, thereby increasing the centrifugal force of the end-suction pump under low consumption conditions and increasing the pressure and flow rate of the discharged liquid.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0033] Example: Figure 1-Figure 10As shown, the present invention provides a technical solution of a horizontal end-suction pump with a multi-stage filtering function that is easy to maintain, including an end-suction pump body 1 and a controller 11, the end-suction pump body 1 includes a base frame 12, an adjustment component 2, a filter component 3 and a volute 13 are installed above the base frame 12, a drive motor 14 is installed above the adjustment component 2, a mounting plate 141 and an impeller 4 are installed at the output end of the drive motor 14, the mounting plate 141 is installed at one end close to the drive motor 14, the impeller 4 is installed at one end away from the drive motor 14, the mounting plate 141 cooperates with the back of the volute 13, a magnetic assist component 5 is provided inside the volute 13, and the magnetic assist component 5 cooperates with the impeller 4;

[0034] When the device is in use, the driving motor 14 can drive the impeller 4 to rotate, and under the drive of the adjusting component 2, the driving motor 14 and the impeller 4 can be driven to move, so that the impeller 4 can be connected to the volute 13, and then when the water inlet of the volute 13 is connected to the external water source, the driving motor 14 can drive the impeller 4 to suck the liquid, and the sucked liquid will first pass through the filter component 3, and the liquid will be preliminarily filtered by the filter component 3, and the magnetic assist component 5 of the device can cooperate with the impeller 4 to make the impeller 4 rotate faster and increase the flow rate of the liquid. When the device needs regular maintenance, it is necessary to disassemble the mounting plate 141 and the volute 13, and then control the adjusting component 2 to adjust itself and the position of the driving motor 14, so as to better observe whether the impeller 4 is damaged.

[0035] like Figure 1-3 and Figure 6 As shown, in this embodiment, specifically, the impeller 4 includes a front cover plate 41, a rear cover plate 42 and a blade group 6, the blade group 6 includes a plurality of groups of booster blades 61 and a plurality of groups of working blades 62, the booster blades 61 are provided with a plurality of groups of booster grooves 611, and the plurality of groups of booster grooves 611 are provided on the booster blades 61 at unequal intervals;

[0036] When in use, the impeller 4 of the device can rotate in the volute 13. When rotating forward, the centrifugal force generated can attract external liquid into the volute 13 and discharge it from the water outlet of the volute 13. The booster blades 61 of the impeller 4 can temporarily store particles in the water, and at the same time can increase the pushed liquid, thereby increasing the flow rate of the water outlet, because when the external liquid passes through the filter component 3, the flow rate of the liquid will decrease, and the booster blades 61 can increase the reduced flow rate. When the device stops working, the water outlet of the volute 13 can be connected to a water source, and the impeller 4 can be driven to reverse by the driving motor 14, so that some particles remaining in the booster groove 611 can be discharged.

[0037] like Figure 3As shown, in this embodiment, specifically, the front cover plate 41 and the rear cover plate 42 are respectively installed on both sides of the plurality of blade groups 6, the front cover plate 41 is installed at the end of the blade group 6 away from the drive motor 14, and the rear cover plate 42 is installed at the end of the blade group 6 close to the mounting plate 141, and the front cover plate 41 is equidistantly installed on one side close to the water inlet of the volute 13 with a plurality of groups of positive magnets, and the positive magnets cooperate with the magnetic assist assembly 5;

[0038] The front cover plate 41 and the rear cover plate 42 of the device can better limit the blade group 6, and the positive pole magnet of the front cover plate 41 can cooperate with the magnetic assist component 5, thereby driving the entire impeller 4 to increase the rotation speed to a certain extent, thereby making up for part of the missing flow rate.

[0039] like Figure 3 As shown, in this embodiment, specifically, the magnetic assist assembly 5 includes a limit ring 51, the limit ring 51 is installed at the water inlet of the volute 13, and multiple groups of negative pole magnets are installed on the limit ring 51, and the negative pole magnets cooperate with the positive pole magnets;

[0040] The magnetic assist component 5 of the device can increase the speed of the impeller 4 to a certain extent. When in use, the limit ring 51 and the front cover plate 41 are parallel to each other, and a plurality of groups of negative pole magnets are provided on the limit ring 51. The negative pole magnets and the positive pole magnets attract each other, thereby increasing the speed of the impeller 4. When the speed of the impeller 4 is increased, the centrifugal force generated can attract more liquid and increase the flow rate of the liquid.

[0041] like Figure 1-2 As shown, in this embodiment, specifically, the filter assembly 3 includes a mounting ring 31, and multiple groups of elastic fiber lines are interspersed between the mounting rings 31. The two ends of the multiple groups of elastic fiber lines are respectively connected to four groups of tightening assemblies 8, and the four groups of tightening assemblies 8 are respectively equidistantly installed outside the mounting ring 31;

[0042] When the filter assembly 3 of the device is in use, it can filter the liquid before entering the volute 13. When in use, impurities in the liquid can be filtered through multiple groups of interlaced elastic fiber lines. Because the elastic fiber lines are connected to the tightening assembly 8, when the tightening assembly 8 is rotated, the elastic fiber lines can be tightened, thereby effectively blocking impurities. When the tightening assembly 8 is relaxed, the elastic fiber lines will be relaxed, and then under the impact of impurities and liquid, the multiple groups of elastic fiber lines will form a net bag state, thereby filtering larger garbage. At the same time, the amount of filtered materials can be increased, and the filter component 3 of the device can not only be used on the end suction pump; because the elastic fiber lines are cross-interspersed on the mounting ring 31, and the elastic fiber lines passing through the same side of the mounting ring 31 are connected to the tightening component 8, the four groups of tightening components 8 evenly limit the elastic fiber lines, and the elastic fiber lines acted by the two opposite groups of tightening components 8 are the same group, and then when the two opposite groups of tightening components 8 are tightening the elastic fiber lines, the tightness of the elastic fiber lines can be tightened, and when the elastic fiber lines are loosened, the opposite is true.

[0043] like Figure 7 , Figure 9-10 As shown, in this embodiment, specifically, the tightening assembly 8 includes a fixed block 81, and a fixed tooth 82 is installed on one side of the fixed block 81 away from the mounting ring 31, and a rotating tooth 83 is installed on the other side of the fixed tooth 82 through a bearing. The fixed tooth 82 and the rotating tooth 83 are the same gears, and a driving tooth 84 is slidably installed outside the fixed tooth 82 and the rotating tooth 83, and the elastic fiber line is connected to the driving tooth 84 through the fixed block 81;

[0044] Because the elastic fiber line passes through the fixed block 81 and is connected to the driving tooth 84, when the tightening assembly 8 is used, when the driving tooth 84 rotates, it will drive the elastic fiber line between the mounting ring 31 to be tightened. However, when the driving tooth 84 is rotated, the driving tooth 84 and the rotating tooth 83 need to be on the same horizontal plane. When the driving tooth 84 needs to be locked, it is only necessary to move the driving tooth 84 to the fixed tooth 82 to limit the driving tooth 84. Because the driving tooth 84 can move between the fixed tooth 82 and the rotating tooth 83, it can cooperate with the fixed tooth 82 and the rotating tooth 83 respectively. When tightening or loosening the elastic fiber line, it is only necessary to move the driving tooth 84 to cooperate with the rotating tooth 83 and rotate the driving tooth 84, because one end of the elastic fiber line is fixedly connected to the driving tooth 84, and then when the driving tooth 84 rotates, the elastic fiber line will be wound around the tightening component 8, thereby tightening the elastic fiber line between the mounting rings 31. When tightened to a suitable state, it is necessary to cooperate the driving tooth 84 with the fixed tooth 82 to limit the current rotation angle of the driving tooth 84, so that by rotating the tightening component 8, the elastic fiber line between the mounting rings 31 can be tightened.

[0045] like Figure 1-4 As shown, in this embodiment, specifically, a support rod 121 and a fixing plate 122 are installed between the base frame 12, the support rod 121 is installed in the middle of the base frame 12, two groups of limit rods 123 are installed between the support rod 121 and the base frame 12, the base frame 12 is located at another blank area of ​​the support rod 121 The fixing plate 122 is installed, and a telescopic cylinder 124 is installed above the fixing plate 122, and the output end of the telescopic cylinder 124 is connected to the adjustment component 2;

[0046] The base frame 12 of the device mainly plays a supporting role, and the telescopic cylinder 124 on the base frame 12 can push the adjustment component 2 to move, so that the position of the adjustment component 2 can be adjusted when the device is disassembled.

[0047] like Figure 4 As shown, in this embodiment, specifically, the adjustment component 2 includes a support plate 21, and slide grooves 211 are installed on both sides of the support plate 21, and the slide grooves 211 cooperate with the base frame 12, and multiple groups of roller assemblies 7 are installed at the bottom of the support plate 21, and bearings are installed on the support plate 21, and the bearings are embedded and installed on the support plate 21, and a motor support plate 22 is installed on the support plate 21, and a connecting rod is installed at the bottom of the motor support plate 22, and the connecting rod is connected to the bearing on the support plate 21, and the drive motor 14 is installed on the motor support plate 22;

[0048] The adjustment component 2 of the device can adjust the position of the driving motor 14. During specific use, the telescopic cylinder 124 can push the support plate 21 to move, and then the support plate 21 will move on the limit rod 123 on the base frame 12 with the assistance of the slide groove 211 and the roller assembly 7. And because the motor support plate 22 is connected to the bearing through the connecting rod, the motor support plate 22 can rotate on the support plate 21.

[0049] like Figure 5 As shown, in this embodiment, specifically, a U-shaped frame 23 is installed at the bottom of the support plate 21, and the U-shaped frame 23 is located between the base frame 12 and the two sets of limit rods 123. An adjustment motor 24 is installed on the U-shaped frame 23, and the adjustment motor 24 is connected to the connecting rod through the bearing on the support plate 21, and the adjustment motor 24 is connected to the controller 11;

[0050] The U-shaped frame 23 at the bottom of the support plate 21 can play a supporting role. Specifically, it can support the adjusting motor 24. When the adjusting motor 24 rotates, it can drive the connecting rod to rotate, and then drive the motor support plate 22 to rotate, so as to adjust the direction of the driving motor 14.

[0051] like Figure 4 and Figure 8As shown, in this embodiment, specifically, the roller assembly 7 includes a support frame 71, a pulley 72 is installed between the support frames 71 through bearings, an adjusting cylinder 73 and a fixed frame 74 are installed at both ends of the support frame 71, the fixed frame 74 is connected to the support frame 71 through bearings, the output end of the adjusting cylinder 73 is connected to the support frame 71, the fixed end of the adjusting cylinder 73 and the fixed end of the fixed frame 74 are respectively connected to the bottom surface of the support plate 21, and the adjusting cylinder 73 is connected to the controller 11;

[0052] The roller assembly 7 of the device can cooperate with the limit rod 123 to realize the movement of the adjustment assembly 2 on the limit rod 123. During specific use, the adjustment cylinder 73 can adjust the angle of one end of the support frame 71, thereby raising the support plate 21, and then raising the current position of the drive motor 14, so as to better cooperate with different volutes 13.

[0053] Working principle: When the device is in use, the driving motor 14 can drive the impeller 4 to rotate, and under the drive of the adjusting component 2, the driving motor 14 and the impeller 4 can be driven to move, so that the impeller 4 can be connected to the volute 13, and then when the water inlet of the volute 13 is connected to the external water source, the driving motor 14 can drive the impeller 4 to suck the liquid, and the sucked liquid will first pass through the filter component 3, and the liquid will be preliminarily filtered by the filter component 3, and the magnetic assist component 5 of the device can cooperate with the impeller 4 to make the impeller 4 rotate faster and increase the flow rate of the liquid. When the device needs regular maintenance, it is necessary to disassemble the mounting plate 141 and the volute 13, and then control the adjusting component 2 to adjust itself and the position of the driving motor 14, so as to better observe whether the impeller 4 is damaged.
