Description

Technical Field

[0001] The utility model relates to the technical field of water supply equipment, in particular to an energy-saving multi-stage pump for water supply equipment. Background Art

[0002] A conventional multi-stage pump is a centrifugal pump that is composed of an inlet and outlet section and a middle section, connected by a tie rod. Its output water pressure can be very high, and it also relies on the rotation of the impeller to obtain centrifugal force. When the gas density reaches the working range of the mechanical vacuum pump, it is extracted, and thus a high vacuum is gradually achieved. The multi-stage pump relies on the change of the pump chamber volume to achieve suction, compression and exhaust, so it is a centrifugal pump with variable volume. However, the existing multi-stage pump needs to maintain a certain working intensity at all times, resulting in high overall energy consumption.

[0003] In the prior art, for example, announcement number CN216407178U proposes a multi-stage pump for energy-saving water supply equipment. This technical solution relates to the technical field of water supply equipment and discloses a multi-stage pump for energy-saving water supply equipment, including a treatment box, on which a primary water inlet mechanism and a terminal water outlet mechanism are provided; the primary water inlet mechanism includes a water inlet chamber provided at one end of the treatment box, a water inlet pipe connected thereto is provided on the side of the water inlet chamber close to the ground, the internal rotation of the water inlet pipe is connected to a first rotating shaft, and a spiral blade is provided on the first rotating shaft; the terminal water outlet mechanism includes a partition vertically provided in the middle of the treatment box, a one-way valve assembly is provided on the side of the partition close to the ground, a piston is slidably connected to the side of the treatment box away from the primary water inlet mechanism, and a push rod is provided on the piston that is slidably connected to the treatment box. The utility model is suitable for a multi-stage pump for energy-saving water supply equipment, which adjusts the working power of the first drive motor and the second drive motor respectively, so that the device can work at the lowest power, thereby improving the energy utilization rate of the entire device;

[0004] However, when the multi-stage pump of the water supply equipment of the prior art is used, water flows into the filter chamber inside the treatment box and is filtered through the filter plate. After the device has been used for a period of time, a large amount of impurities will accumulate on the filter plate, which not only affects the filtering efficiency of the device for the water flow, but also easily causes clogging of the filter plate, resulting in the device not being able to operate normally. Therefore, during the use of the device, the staff needs to frequently clean the impurities on the filter plate, which is time-consuming and labor-intensive, making the use of the device more inconvenient.

[0005] In order to solve the above problems, this application proposes an energy-saving multi-stage pump for water supply equipment. Utility Model Content

[0006] The utility model is intended to provide an energy-saving multi-stage pump for water supply equipment, which is mainly used to solve the problem that the existing multi-stage pump for water supply equipment needs to frequently clean impurities on the filter plate, which is time-consuming and labor-intensive, making the device inconvenient to use.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A multi-stage pump for energy-saving water supply equipment includes a treatment box, a filter chamber and a filter plate arranged inside the filter chamber. The top of the treatment box is connected to the opening of the filter chamber with an inspection cover, and screws are passed through the four corners of the inspection cover, which are threadedly connected to the treatment box. The top of the inspection cover is fixedly connected to a mounting box, and a motor is fixedly installed inside the mounting box. The output end of the motor is fixedly connected to a rotating rod, and the lower end of the rotating rod extends to the inner wall of the treatment box, and the rotating rod is rotatably connected to the treatment box. The outer wall of the rotating rod is fixedly connected to multiple stirring rods, and the lower end of the outer wall of the rotating rod is provided with a cleaning component for cleaning the filter plate.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When the multi-stage pump of the water supply equipment is used, (the lower end of the water inlet pipe is inserted into the water source, the water can move upward into the water inlet chamber, and enter the left side of the treatment box through the water inlet, and after being filtered by the filter plate, it will flow into the lower left side, and the water can enter the right side of the treatment box through the water port. The second drive motor is used to make the piston move up and down. When the piston moves downward, the pressure under the piston increases. At this time, the cover plate blocks the water port, and the water on the right side of the treatment box is discharged through the water outlet pipe. When the piston moves upward, the cover plate opens, and the water on the left side of the treatment box enters The right side of the treatment box, so that the water flow can be discharged intermittently), the existing technology is in brackets, and this application document does not elaborate on it. During the operation of the device, the motor inside the installation box is connected to the power supply, and the motor is started. The motor operation can rotate the rotating rod, and the stirring rod can be rotated at the same time, thereby having a better stirring effect on the water inside the filter chamber. This can effectively prevent impurities in the water from settling on the filter plate and causing blockage. At the same time, the filter plate can be cleaned by the cleaning component provided at the lower end of the outer wall of the rotating rod, thereby effectively ensuring the normal operation of the device.

[0011] 2. Beneficial effects: During the operation of the device, the motor is started, and the operation of the motor can drive the rotating rod to drive the stirring rod to rotate, thereby achieving a better stirring effect on the water inside the filter chamber, which can effectively prevent impurities in the water from settling on the filter plate and causing blockage. Through the cleaning component provided at the lower end of the outer wall of the rotating rod, the cleaning component can clean the filter plate at the same time when the motor is operating, which can effectively reduce the frequency of cleaning the filter plate by the staff, thereby making the use of the device more convenient. The inspection cover is fixed to the treatment box with screws. When the inside of the treatment box is damaged, the inspection cover can be removed, thereby facilitating the staff to inspect the inside of the treatment box.

[0012] Preferably, the cleaning assembly includes a connecting rod connected to the lower end of the outer wall of the rotating rod, and the connecting rod is symmetrically arranged at the lower end of the outer wall of the rotating rod, one end of the connecting rod is fixedly connected to a plug block, and the lower end of the outer wall of the rotating rod is provided with a slot matching the plug block, and a limiting assembly is provided on the plug block, and a brush is fixedly connected to the bottom of the connecting rod. During the operation of the device, starting the motor can make the rotating rod drive the connecting rod to rotate. While the connecting rod rotates, the surface of the filter plate can be brushed by the brush provided at its bottom. This can effectively reduce the frequency of cleaning the filter plate by the staff. After the plug block at one end of the connecting rod is inserted into the slot on the rotating rod, it is fixed by the limiting assembly, so that the staff can disassemble the connecting rod, thereby facilitating people to clean and replace the brush.

[0013] Preferably, the limit assembly includes a sliding cavity opened at the connection between the connecting rod and the plug block, the sliding cavity is slidably connected to a sliding plate, the inner wall of the sliding cavity is fixedly connected to a spring on the side away from the opening, the other end of the spring is fixedly connected to the sliding plate, the sliding plate is fixedly connected to a button and a wedge block on the side away from the spring, a connecting rod extends from the side of the button away from the sliding plate, and the button is slidably connected to the connecting rod, an plug block extends from the side of the wedge block away from the sliding plate, and the wedge block is slidably connected to the plug block, a limiting groove matching the wedge block is opened on the inner wall of the slot, and the brush needs to be cleaned or replaced when the device is used for a long time. When the cam is fully inserted into the slot, the wedge block will pop out under the action of the spring and engage with the limit slot, thus completing the installation of the connecting rod. This makes it easier to disassemble and assemble the connecting rod, making it convenient for the staff to clean or replace the brush on the connecting rod.

[0014] Preferably, the screw is an embedded hexagonal setting, and the upper end surface of the screw is not higher than the top of the inspection cover. After the screw is installed, the upper end surface of the screw is not higher than the top of the inspection cover, so that it will not protrude and cause wear. The screw is an embedded hexagonal setting. The screw with an embedded hexagonal setting can rotate better during installation, reducing the possibility of slip angle.

[0015] Preferably, multiple ventilation holes are provided on both sides of the installation box, and the inner walls of the ventilation holes are fixedly connected with filter nets. The motor inside the installation box will generate a certain amount of heat when it is operating. The multiple ventilation holes on both sides of the installation box can achieve a better heat dissipation effect on the motor inside the installation box. The filter nets arranged on the inner walls of the ventilation holes can effectively prevent external dust from entering the motor through the ventilation holes, thereby effectively ensuring the normal operation of the device.

[0016] Preferably, there are multiple springs inside the sliding cavity, and the springs are evenly distributed in a linear array inside the sliding cavity. By setting the number of springs inside the sliding cavity to multiple, multiple springs can exert a greater thrust on the sliding plate, so that when the wedge block on the sliding plate is engaged with the limit groove, it can have a better fixing effect on the connecting rod, thereby making the device more stable during operation.

[0017] Preferably, the corners at the opening of the inner wall of the slot are all chamfered. By setting the corners at the opening of the inner wall of the slot as chamfers, it is easier to insert the plug into the slot, thereby making the installation of the connecting rod easier.

The plurality of ventilation holes 20 can achieve a good heat dissipation effect for the motor 7 inside the installation box 6. The inner walls of the ventilation holes 20 are fixedly connected with a filter screen, which can effectively prevent external dust from entering the motor 7 through the ventilation holes 20, thereby effectively ensuring the normal operation of the device.

During the operation of the device, the motor 7 inside the installation box 6 is powered on and the motor 7 is started. The rotating rod 8 can rotate by the operation of the motor 7. When the rotating rod 8 rotates, the stirring rod 9 can rotate at the same time, thereby achieving a good stirring effect on the water inside the filter chamber 2. This can effectively prevent impurities in the water from being precipitated on the filter plate 3 and causing it to be blocked. The lower end of the outer wall of the rotating rod 8 is provided with a cleaning component for cleaning the filter plate 3. The cleaning component can clean the filter plate 3 at the same time, which can effectively reduce the frequency of cleaning the filter plate 3 by the staff, thereby making the use of the device more convenient.

[0026] like Figure 2 and Figure 4After the plug block 12 at one end of the connecting rod 10 is inserted into the slot 13 on the rotating rod 8, it is fixed by the limiting assembly, so that the staff can disassemble the connecting rod 10, thereby facilitating people to clean and replace the brush 11.

[0027] like Figure 2 and Figure 5 As shown, the limiting assembly includes a sliding cavity 14 opened at the connection between the connecting rod 10 and the plug block 12, and a sliding plate 15 is slidably connected inside the sliding cavity 14. A plurality of springs 16 are fixedly connected to the side of the inner wall of the sliding cavity 14 away from the opening, and the other end of the spring 16 is fixedly connected to the sliding plate 15. A button 19 and a wedge block 17 are fixedly connected to the side of the sliding plate 15 away from the spring 16. The button 19 extends from the connecting rod 10 on the side away from the sliding plate 15, and the button 19 is slidably connected to the connecting rod 10. The wedge block 17 extends from the plug block 12 on the side away from the sliding plate 15, and the wedge block 17 is slidably connected to the plug block 12.

When the piston moves downward, the pressure below the piston increases. At this time, the cover plate blocks the water port, and the water on the right side of the treatment box is discharged through the water outlet pipe. When the piston moves upward, the cover plate opens, and the water on the left side of the treatment box enters the right side of the treatment box, so that the water flow can be discharged intermittently). The information in brackets is the prior art, and this application document does not elaborate on it. During the operation of the device, the motor 7 inside the installation box 6 is connected to the power supply and the motor 7 is started. The operation of the motor 7 can rotate the rotating rod 8. When the rotating rod 8 rotates, the stirring rod 9 can rotate, thereby having a better stirring effect on the water inside the filter chamber 2, which can effectively prevent impurities in the water from settling on the filter plate 3 and causing it to be blocked. When the rotating rod 8 rotates, the connecting rod 10 can be driven to rotate. The connecting rod 10 rotates to brush the surface of the filter plate 3 through the brush 11 set at the bottom thereof, which can effectively reduce the frequency of cleaning of the filter plate 3 by the staff. When the brush 11 needs to be cleaned or replaced, the screw 5 on the inspection cover 4 can be removed to remove the inspection cover 4 from the top of the processing box 1. Pressing the button 19 on the connecting rod 10 can drive the wedge block 17 to move downward through the sliding plate 15. When the wedge block 17 is out of the limit groove 18 on the inner wall of the slot 13, the connecting rod 10 can be removed from the rotating rod 8. It is convenient for people to clean or replace the brush 11 on the connecting rod 10. When installing the connecting rod 10, the plug 12 at one end of the connecting rod 10 is inserted into the slot 13 on the rotating rod 8. The wedge block 17 is squeezed and moves downward, while squeezing the spring 16 and compressing it. When the plug 12 is fully inserted into the slot 13, the wedge block 17 will pop out under the action of the spring 16 and engage with the limit groove 18, and the installation of the connecting rod 10 is completed. Then the inspection cover 4 is fixed to the processing box 1 with screws 5, and the device can be used normally.
