Abstract
Description
Technical Field
[0001] This utility model relates to the field of circulating water pump technology, specifically a low-cavitation circulating water pump for waste treatment. Background Technology
[0002] Cavitation occurs when air bubbles, guided by water flow, move to a high-pressure area and collapse upon compression, leading to a deterioration in hydraulic performance. This can damage components and corrode metal materials. To mitigate this, proper pipe installation and timely removal of accumulated debris are necessary to prevent reduced suction or damage to internal blades.
[0003] In the process of waste disposal, water pumps are needed to pump out waste liquid. However, in the past, water pumps would clean out a large amount of garbage in the sewage before pumping through the water pipe. If small waste materials were sucked into the water pump, it would cause problems such as jamming and scratching of the blades. Without protective measures, problems such as cavitation would follow.
[0004] Now, a novel low-cavitation circulating water pump for waste treatment is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a low-cavitation circulating water pump for waste treatment, in order to solve the problem of lack of protection of the internal structure mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-cavitation circulating water pump for waste treatment, comprising a housing and blades. Blades are movably connected to the center of the right side inside the housing. A connecting shell is welded to the center of the right side of the housing, and a motor is installed on the right side of the connecting shell. A rotating shaft is movably connected to the right side inside the connecting shell, and a bearing is installed between the left side of the rotating shaft and the blades. A water outlet pipe is welded to the top of the housing. An inlet pipe is fixedly connected to the left side of the housing, and a retainer is snapped into the left side of the inlet pipe. A retaining block is welded to the upper and lower sides of the right side inside the retaining block. A retaining groove is respectively provided at the upper and lower sides of the left side of the inlet pipe. A screen box is horizontally fixed to the center of the inside of the retaining block, and a baffle is fixed between the upper and lower sides of the right side inside the inlet pipe.
[0007] Preferably, the right side of the sieve box is attached to the baffle plate, and the locking block is embedded in the locking groove.
[0008] Preferably, the motor can guide the rotating shaft to rotate laterally, and the blades can rotate with the rotating shaft inside the housing.
[0009] Preferably, an oil reservoir is installed on the upper part of the outer shell of the connecting shell, and an oil pump is fixed at the center of the lower part of the oil reservoir. Sliding balls are embedded in the upper and lower parts of the outer shell of the bearing. A slot is provided in the upper part of the inner shell of the connecting shell, and vertical rods are fixed on both sides of the upper part of the slot. A sleeve is sleeved on the outside of the vertical rod, and a spring is welded between the top of the sleeve and the slot. A brush head is welded at the center between the sleeves, and a hose is fixedly connected between the oil pump and the brush head.
[0010] Preferably, the spring is sleeved on the outside of the vertical rod, and the sleeve can slide up and down along the surface of the vertical rod.
[0011] Preferably, the brush head is attached to the surface of the ball bearing, and the bearing can rotate laterally within the connecting housing.
[0012] Preferably, a short rod is fixed to the bottom of the outer casing, a long rod is fixed to the bottom of the motor, a rotating disk is welded between the bottom of the short rod and the long rod, and a sleeve is provided at the center of the rotating disk. A base is fitted onto the bottom of the rotating disk, and a sound-absorbing pad is fixed below the base. Screw holes are provided on both sides of the top of the base. A positioning hole is provided around the edge of the rotating disk surface, and a bolt is fitted between the positioning hole and the screw hole. A limit rod is welded to the center of the top of the base, and ball bearings are embedded on both sides of the bottom of the rotating disk.
[0013] Preferably, the limiting rod is embedded in the sleeve, and the rotating disk can rotate horizontally in the base.
[0014] Compared with the prior art, the beneficial effects of this utility model are: the low cavitation circulating water pump for waste treatment not only achieves pre-isolation of waste and stability when the bearings and shafts rotate, but also allows for convenient adjustment of the pump orientation;
[0015] (1) By fixing the inlet pipe to the left side of the outer shell, the ferrule is fixed to the surface of the inlet pipe from the left side. The ferrule's internal ferrule is also embedded in the slot, which facilitates the connection of the external conveying pipe and allows the screen box to be pressed against the side of the baffle to pre-filter the garbage entering the outer shell, isolate the fine garbage remaining in the sewage, and maintain the normal operation of the inner shell by rotating the motor shaft and blades, thus reducing the probability of cavitation.
[0016] (2) By welding a brush head at the center between the sleeves, the oil pump is turned on periodically, and the lubricating oil in the oil storage box is introduced into the brush head through the hose. Whenever the bearing rotates with the shaft, the brush head will contact the ball and apply oil. The vertical rods embedded in the sleeves on both sides will also restrict the movement of the brush head under the support of the spring, so as to prevent the bearing from jamming and reduce the corresponding frictional resistance.
[0017] (3) By attaching a base to the bottom of the rotary table, the short rod and long rod used to support the outer shell and motor are restricted by the rotary table. Since the limiting rod is embedded in the sleeve, the direction of the water inlet of the outer shell can be changed when the rotary table is rotated along the top of the base. After aligning the screw hole and positioning hole, the bolt is screwed in for reinforcement. With the sound-absorbing pad at the bottom, the noise can be reduced, and it is convenient to introduce sewage from different directions and discharge it to other places. Attached Figure Description

[0024] Please see Figure 1-4An embodiment of this utility model provides a low cavitation circulating water pump for waste treatment, comprising a housing 1 and blades 10. Blades 10 are movably connected to the center of the right side inside the housing 1. A connecting shell 12 is welded to the center of the right side of the housing 1, and a motor 13 is installed on the right side of the connecting shell 12. A rotating shaft 5 is movably connected to the right side inside the connecting shell 12, and a bearing 24 is installed between the left side of the rotating shaft 5 and the blades 10.

A screen box 7 is horizontally fixed to the center of the inside of the sleeve 3. A baffle 8 is fixed between the upper and lower sides of the right side inside the inlet pipe 2.
[0025] The right side of the sieve box 7 is attached to the baffle 8, the locking block 6 is embedded in the slot 4, the motor 13 can guide the rotating shaft 5 to rotate laterally, and the blade 10 can rotate with the rotating shaft 5 inside the outer shell 1.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, the sleeve 3 is fixed to the surface of the inlet pipe 2 from the left side, and the card blocks 6 inside the sleeve 3 are also embedded in the card slots 4. This facilitates the connection of the external conveying pipe and also allows the screen box 7 to be pressed against the side of the baffle 8 to pre-filter the garbage entering the housing 1, thus isolating the small garbage remaining in the sewage. The motor 13 controls the rotation of the shaft 5 and the blades 10 to maintain the normal operation of the housing 1.
[0027] An oil reservoir 11 is installed on the upper part of the outer shell 12, and an oil pump 23 is fixed at the lower center of the oil reservoir 11. Sliding balls 25 are embedded in the upper and lower parts of the outer shell 24. A slot 32 is provided in the upper part of the inner shell 12, and vertical rods 27 are fixed on both sides of the upper part of the slot 32. A sleeve 28 is sleeved on the outside of the vertical rod 27, and a spring 29 is welded between the top of the sleeve 28 and the slot 32. A brush head 26 is welded at the center between the sleeves 28. A hose 22 is fixedly connected between the oil pump 23 and the brush head 26.
[0028] Spring 29 is sleeved on the outside of vertical rod 27, sleeve 28 can slide up and down along the surface of vertical rod 27, brush head 26 is attached to the surface of ball bearing 25, and bearing 24 can rotate laterally in connecting shell 12.
[0029] Specifically, such as Figure 1 and Figure 3As shown, the oil pump 23 is turned on periodically, and the lubricating oil in the oil storage box 11 is introduced into the brush head 26 through the hose 22. Whenever the bearing 24 rotates with the shaft 5, the brush head 26 will contact the ball bearing 25 and apply oil. The vertical rods 27 embedded in the sleeve 28 on both sides will also restrict the movement of the brush head 26 under the support of the spring 29 to prevent the bearing 24 from jamming.
[0030] A short rod 20 is fixed to the bottom of the outer casing 1, and a long rod 14 is fixed to the bottom of the motor 13. A rotating disk 33 is welded between the bottom of the short rod 20 and the long rod 14, and a sleeve 19 is provided at the center of the inside of the rotating disk 33. A base 15 is sleeved on the bottom of the rotating disk 33, and a sound-absorbing pad 16 is fixed below the base 15. Screw holes 31 are provided on both sides of the top of the base 15. A positioning hole 30 is provided around the edge of the rotating disk 33, and a bolt 21 is fitted between the positioning hole 30 and the screw hole 31.

The rotating disk 33 can rotate horizontally in the base 15.
[0031] Specifically, such as Figure 1 and Figure 4 As shown, the short rod 20 and long rod 14 used to support the housing 1 and motor 13 are restricted by the rotating disk 33. Since the limiting rod 18 is embedded in the sleeve 19, the direction of the water inlet of the housing 1 can be changed when the rotating disk 33 is rotated along the top of the base 15. After aligning the screw hole 31 and the positioning hole 30, the bolt 21 is screwed in for reinforcement. The noise can be reduced by the sound-absorbing pad 16 at the bottom.
[0032] Working principle: In use, the short rod 20 and long rod 14 supporting the outer shell 1 and motor 13 are restricted by the rotating disc 33. Because the limiting rod 18 is embedded in the sleeve 19, rotating the rotating disc 33 along the top of the base 15 can change the direction of the water inlet of the outer shell 1. After aligning the screw hole 31 and the positioning hole 30, the bolt 21 is screwed in for reinforcement. Then, the clamping sleeve 3 is fixed to the surface of the liquid inlet pipe 2 from the left side. The clamping blocks 6 inside the clamping sleeve 3 are also embedded in the clamping grooves 4, which facilitates the connection of the external conveying pipe and also allows the screen box 7 to be pressed against the baffle 8. On the side, the waste inside the input housing 1 is pre-filtered and separated to isolate the fine waste remaining in the sewage. The motor 13 controls the rotation of the shaft 5 and the blades 10 to maintain the normal operation inside the housing 1. The oil pump 23 is turned on periodically to introduce the lubricating oil in the oil storage box 11 into the brush head 26 through the hose 22. Whenever the bearing 24 rotates with the shaft 5, the brush head 26 will contact the ball bearing 25 and apply oil. The vertical rods 27 embedded in the sleeves 28 on both sides will also restrict the movement of the brush head 26 under the support of the springs 29 to prevent the bearing 24 from jamming.
