Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, and in particular to a centrifugal pump volute polishing device. Background Technology

[0002] For example, a patent entitled "A Polishing Device for the Scroll of a Slurry Water Circulation Pump" (patent application number: CN202121325495.7) discloses a polishing device for the scroll of a slurry water circulation pump. By adjusting the settings of the components, scrolls of different sizes can be fixed and limited, which increases the practicality of the fixtures in the abrasive flow machine tool and avoids frequent fixture changes, thereby improving the polishing efficiency. However, in actual use, the device lacks a chip handling mechanism, and the chips ground off will continuously mix into the abrasive, which can easily scratch the polished surface. The efficiency of use needs to be improved.

[0003] For example, a patent entitled "A Construction Waste Crushing, Screening and Mixing Machine" (patent application number: CN202022043268.7) discloses a construction waste crushing, screening and mixing machine. It uses two inclined magnetic screening plates to screen the crushed construction waste. The stones slide down the magnetic screening plates and are eventually discharged from the outlet, while the steel bars are attracted to the magnetic screening plates. After the stones are discharged, the electromagnets in the magnetic screening plates can be turned off to remove the steel bars. However, it is difficult to make the stones evenly distributed on the magnetic screening plates, which affects the screening efficiency.

[0004] Therefore, it is necessary to propose a centrifugal pump volute polishing device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a centrifugal pump volute polishing device to solve the problem that the device lacks a debris handling mechanism during actual use, and the debris will continuously mix with the abrasive, easily scratching the polished surface, and the efficiency needs to be improved.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a centrifugal pump volute polishing device, comprising an abrasive tank, an outlet pipe installed on the abrasive tank, a pump for siphoning the contents of the abrasive tank installed at the top of the abrasive tank, an inlet pipe connected to the outlet end of the pump, and a sealing element installed on the end of the inlet pipe and the outlet pipe that are close to each other.

[0007] The abrasive tank is equipped with a processing box, and the processing box is equipped with inclined sliding plates. The bottom end of the sliding plate is rotatably mounted on the inner wall of the processing box. An electromagnet is installed inside the wall of the sliding plate. The processing box is equipped with a sliding base, and the bottom end of the discharge pipe is fixed on the sliding base and faces the sliding plate.

[0008] During polishing, the slide causes the bottom of the discharge tube to move back and forth along the length of the slide plate, while the top of the slide plate swings back and forth.

[0009] The processing box is rotatably equipped with a reciprocating lead screw, and the slide has a threaded hole that mates with the reciprocating lead screw. The processing box is fixedly equipped with a guide rod, and the slide has a round hole that mates with the guide rod. A motor is fixedly connected to the outer wall of the processing box, and the reciprocating lead screw is fixedly connected to the drive shaft of the motor.

[0010] A shaft is rotatably mounted on the processing box. The shaft is located on the side of the slide plate facing away from the slide base. A stop block is fixedly connected to the shaft, and the stop block abuts against the slide plate.

[0011] A transmission assembly is provided between the reciprocating screw and the shaft. The transmission assembly includes a first sprocket, a second sprocket, and a chain. The first sprocket is fixedly connected to the reciprocating screw, and the second sprocket is fixedly connected to the shaft. The first sprocket and the second sprocket are connected by a chain drive.

[0012] A fixed rod is fixedly connected to the processing box, and a spring is fixedly connected to the sliding plate. The end of the spring away from the sliding plate is fixedly connected to the inner wall of the processing box. The fixed rod and the spring are both located on the side of the sliding plate facing away from the slide seat.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention achieves the effect of collecting debris by setting up structures such as a sliding plate, an electromagnet, and a sliding base. It also allows the abrasive to be evenly distributed on the sliding plate, avoiding accumulation and ensuring that the debris is fully processed, thereby improving the efficiency of the centrifugal pump volute polishing device.

[0015] By incorporating structures such as springs, blocks, and transmission components, the top of the slide plate can swing back and forth, causing the abrasive material that remains between the debris to slide downwards and avoid accumulation.

[0016] A single motor synchronizes the movement of the slide block and the swing of the skateboard, reducing energy consumption and making operation convenient. Attached Figure Description

[0023] This utility model provides, for example Figures 1-5 The centrifugal pump volute polishing device shown includes an abrasive tank 1 filled with abrasive. To polish the centrifugal pump volute, a discharge pipe 4 is installed on the abrasive tank 1. The upper half of the discharge pipe 4 is made of a hard material, such as stainless steel, to ensure a stable connection with the abrasive tank 1, while the lower half is made of a soft material, such as rubber. A suction pump 2 is installed at the top of the abrasive tank 1, and a suction pipe is connected to the inlet end of the suction pump 2 to draw abrasive from the inside of the abrasive tank 1. The discharge end of the suction pump 2 is connected to an inlet pipe 3, which is made of a hard material, such as stainless steel.

[0024] The volute is made of materials such as HT250 gray cast iron, and its fragments can be attracted by a magnet.

[0025] Pump 2 is connected to the factory's power supply.

[0026] Both the feed pipe 3 and the discharge pipe 4 are equipped with sealing elements 5 at their respective ends. In actual use, the ends of the feed pipe 3 and the discharge pipe 4 are connected to the inlet and outlet ends of the volute, and the sealing elements 5 ensure a tight seal. When the pump 2 is started, the abrasive is drawn into the pump 2 through the pump pipe, and then enters the volute through the feed pipe 3 to polish the volute. After polishing, the abrasive flows into the abrasive pool 1 through the discharge pipe 4 for recycling. Abrasive polishing is a common technology and will not be described in detail here.

[0027] Furthermore, the abrasive pool 1 is equipped with a clamping assembly to fix the volute. The clamping assembly includes structures such as clamping plates. The clamping assembly is a common existing technology and will not be described in detail here.

[0028] Abrasives can be, but are not limited to, cubic boron nitride, which is a hard, solid, non-magnetic material.

[0029] Considering that when the abrasive flows into the abrasive tank 1 through the discharge pipe 4 for recycling, the grinding debris will continuously mix into the abrasive. If it is not treated in time, the debris will easily scratch the polished surface when it re-enters the pump 2 with the abrasive. In order to treat the debris, a treatment box 6 is installed inside the abrasive tank 1. The treatment box 6 is equipped with inclined sliding plates 7. The bottom of the sliding plates 7 is rotatably mounted on the inner wall of the treatment box 6. An electromagnet 8 is installed inside the wall of the sliding plates 7. The electromagnet 8 is connected to the power supply of the factory.

[0030] When in use, the electromagnet 8 is activated, the slide plate 7 is tilted, the abrasive slides down the inclined surface of the slide plate 7 and is discharged from the bottom of the processing box 6. The debris is adsorbed on the surface of the slide plate 7, which has a collection effect and ensures that the debris will not re-enter the volute.

[0031] Furthermore, the tilt angle of the skateboard 7 is appropriate, such as 35° to 45°, so that the abrasive material can slide down the inclined surface of the skateboard 7 at a suitable speed.

[0032] To ensure that the abrasive can fully contact the slide plate 7, a slide block 14 is provided inside the processing box 6. The bottom end of the discharge pipe 4 is fixed on the slide block 14 and faces the slide plate 7, as shown in the figure. Figure 3 The top of the slide plate 7 is tilted to the left, and the bottom of the discharge pipe 4 is facing the top right side of the slide plate 7. Since the lower half of the discharge pipe 4 is made of soft material, it does not affect the movement of the slide block 14.

[0033] A reciprocating screw 12 is rotatably mounted on the processing box 6. A threaded hole that mates with the reciprocating screw 12 is provided on the slide 14. A guide rod 13 is fixedly mounted on the processing box 6. A round hole that mates with the guide rod 13 is provided on the slide 14. The guide rod 13 is provided so that the slide 14 cannot rotate and can only move along the axial length of the reciprocating screw 12 and the guide rod 13. A motor 9 is fixedly connected to the outer wall of the processing box 6. The reciprocating screw 12 is fixedly connected to the drive shaft of the motor 9.

[0034] Motor 9 is connected to the factory's power supply, and motor 9 can switch between forward and reverse rotation.

[0035] In use, the motor 9 drives the reciprocating screw 12 to rotate forward. Since the slide 14 has a threaded hole that mates with the reciprocating screw 12, and under the limiting action of the guide rod 13 (which prevents the slide 14 from rotating), the slide 14 can move along the axial length direction of the reciprocating screw 12 and the guide rod 13 (i.e., the length direction of the slide plate 7). When the motor 9 drives the reciprocating screw 12 to rotate in reverse, the slide 14 moves in the opposite direction. As the motor 9 continues to run and switches between forward and reverse rotation, the slide 14 will drive the bottom end of the discharge pipe 4 to move back and forth along the axial length direction of the reciprocating screw 12 and the guide rod 13 (i.e., the length direction of the slide plate 7), so that the abrasive is evenly distributed on the slide plate 7, expanding the processing range, avoiding accumulation, and ensuring the chip processing effect.

[0036] This invention, through the arrangement of a slide plate 7, an electromagnet 8, and a slide block 14, achieves the effect of collecting debris and ensures that the abrasive is evenly distributed on the slide plate 7, preventing accumulation and ensuring thorough processing of debris, thereby improving the efficiency of the centrifugal pump volute polishing device.

[0037] Furthermore, the abrasive tank 1 is equipped with a processing window, door panel, etc. (not shown in the figure). After polishing, the operator removes the door panel and the processing window collects the debris from the slide plate 7. A collection box can also be placed at the bottom of the slide plate 7. When the electromagnet 8 is de-energized, the debris falls into the collection box under gravity, achieving centralized cleaning.

[0038] In addition, since the abrasive can be evenly distributed on the slide plate 7 and avoid accumulation, the length of the slide plate 7 can be set to a larger value (the length of the electromagnet 8 can also be set to a larger value) and the width of the slide plate 7 can also be set to a larger value, resulting in a larger adsorption area. When screening the same amount of abrasive, the cleaning cycle can be greatly extended and the operation can be simplified.

[0039] Since the debris is adsorbed on the slide plate 7, the abrasive tends to stay between the debris as it accumulates. To ensure the efficiency of the abrasive sliding, a fixed rod 10 is fixedly connected to the processing box 6 to limit the movement of the slide plate 7. A spring 11 is fixedly connected to the slide plate 7. The end of the spring 11 away from the slide plate 7 is fixedly connected to the inner wall of the processing box 6. The fixed rod 10 and the spring 11 are both located on the side of the slide plate 7 facing away from the slide block 14. The spring 11 is used to assist the slide plate 7 in resetting.

[0040] A shaft 15 is rotatably mounted on the processing box 6. The shaft 15 is located on the side of the slide plate 7 facing away from the slide seat 14. A stop block 16 is fixedly connected to the shaft 15, and the stop block 16 abuts against the slide plate 7.

[0041] A transmission assembly is provided between the reciprocating screw 12 and the shaft 15. The transmission assembly includes a first sprocket 17, a second sprocket 18 and a chain 19. The first sprocket 17 is fixedly connected to the reciprocating screw 12, and the second sprocket 18 is fixedly connected to the shaft 15. The first sprocket 17 and the second sprocket 18 are connected by the chain 19.

[0042] In operation, motor 9 drives reciprocating screw 12 to rotate, and first sprocket 17 rotates synchronously. Since first sprocket 17 and second sprocket 18 are connected by chain 19, second sprocket 18 drives shaft 15 and stop block 16 to rotate. (Refer to...) Figure 3 , Figure 4 When the abutment block 16 contacts the slide plate 7, it squeezes the top of the slide plate 7 to swing to the right. When the abutment block 16 disengages from the slide plate 7, the top of the slide plate 7 swings to the left under the restoring force of the spring 11, so that the top of the slide plate 7 swings back and forth, and the abrasive material that is stuck between the debris slides down to avoid accumulation.

[0043] The top of the slide plate 7 swings back and forth with a suitable amplitude and does not contact the discharge pipe 4. At the same time, the rotation speed of the shaft 15 is relatively small, ensuring that the abrasive can slide down along the slope of the slide plate 7.

[0044] By incorporating structures such as spring 11, stop block 16, and transmission components, the top of the slide plate 7 can swing back and forth, causing the abrasive material remaining between the debris to slide downwards and avoid accumulation.

[0045] When the electromagnet 8 is de-energized, causing the debris to fall into the collection box under gravity, the top of the slide plate 7 can be controlled to swing back and forth to accelerate the falling speed.

[0046] A single motor 9 synchronously moves the slide 14 and swings the skateboard 7, reducing energy consumption and making operation convenient.
