Description

A submersible sewage pump with continuous impurity removal function

technical field

The invention relates to the technical field of sewage pumps, in particular to a submersible sewage pump with continuous impurity removal function.

Background technique

The sewage pump is used to extract sludge or sewage. When the sewage pump is working, it is necessary to place all the sewage pump in the sewage and be submerged in the sewage. When the sewage pump is working, it is located underwater. Therefore, the motor of the sewage pump is a submersible motor, which uses the impeller to rotate at high speed The resulting centrifugal force draws the sewage out.

When the sewage pump pumps the sewage in the sewage tank, if the sludge contains stone particles and other impurities, the sewage pump will pump some of the stone particles and other impurities into the sewage pump, and the stone particles will collide with the impeller in the sewage pump, thus making the sewage discharge The pump trembles, and in serious cases, the sewage pump will dump and collide with the bottom of the sewage pool, causing damage to the sewage pump, and the water inlet of the dumped sewage pump cannot be perpendicular to the bottom of the sewage pool. With the decline of the sewage liquid level, when the sewage liquid level is low When the water inlet of the sewage pump is dumped, the water inlet of the sewage pump is exposed above the liquid level of the sewage, which makes it impossible for the sewage pump to pump sewage in the subsequent process, resulting in a decrease in the amount of sewage finally pumped by the sewage pump, and the intake of the sewage pump that has not been dumped The spout remains below the liquid level and does not reduce the amount of sewage pumped.

Before using the sewage pump to extract the sewage in the sewage pool, the device should be placed in the sewage pool and fixed. The specific operation is as follows: the operator first connects one end of the water pipe to the water outlet 102, and connects the other end of the water pipe. Put it into a new location for storing sewage, and then the operator uses a rope to put the sewage pump into the sewage pool. When the sewage pump moves downward, it should be vertically downward. In the initial state, the three rectangular frames 601 will The first slide bar 602 is limited, and the first slide bar 602 cannot move downward. There is a certain distance between the support ring 603 and the lower side of the pumping housing 1. When the support ring 603 contacts the bottom of the sewage pool, the submersible motor 2 Moving downwards, the support ring 603 is blocked by the bottom of the sewage tank and cannot move downwards, so the support ring 603 is equivalent to the upward movement of the pumping casing 1, and the directions described below are all carried out in the direction that the support ring 603 is equivalent to the pumping casing 1 Narration, the support ring 603 drives the three first slide bars 602 to move upward, as shown in Figure 2 and Figure 3, taking one of the first slide bars 602 as an example, the first slide bar 602 drives the rack 604 to move upward, and the rack 604 drives the first gear 605 to rotate, and the first gear 605 rotates to drive the second gear 606 to rotate, and the second gear 606 drives the first housing 607 and the parts on it to rotate (the first housing 607 takes the axis of the second gear 606 as Turning the central point, the lower part of the first housing 607 gradually moves away from the pumping housing 1).

During the upward movement of the first sliding rod 602, the first sliding rod 602 drives the push plate 703 to move upward through the connecting rod 702, and the push plate 703 squeezes the gas on the upper side of the push plate 703 in the gas storage sleeve 701, and the push plate 703 The gas on the upper side enters the upper side of the rectangular support rod 608 in the first housing 607 through the bellows, the pressure on the upper side of the rectangular support rod 608 in the first housing 607 increases, and the rectangular support rod 608 slides along the first housing 607 and Away from the second gear 606, the rectangular support rod 608 drives the connecting plate 801, the rotating rod 802 and the connecting frame 803 to gradually move away from the second gear 606. As the first sliding rod 602 continues to move upward, the pressure on the upper side of the push plate 703 in the air storage sleeve 701, the inner bellows and the upper side of the rectangular support rod 608 in the first housing 607 increases. When 6021 is flush with the U-shaped rod 704, the first spring 705 in the compressed state resets, and the first spring 705 drives the U-shaped rod 704 away from the pumping housing 1, and the side of the U-shaped rod 704 close to the first sliding rod 602 snaps in In the limit groove 6021, the first slide bar 602 is limited and cannot move upwards. At this time, the support ring 603 is located on the lower side of the filter screen 902, the first housing 607 no longer rotates, and the inner push plate 703 of the air storage sleeve 701 The pressure on the upper side, inside the bellows and on the upper side of the rectangular support rod 608 inside the first housing 607 no longer changes.

During the rotation of the rectangular support rod 608, when the connection frame 803 contacts the bottom of the sewage pool, the connection frame 803 is gradually kept horizontal by the sewage pool extrusion, and finally the lower side of the connection frame 803 is in contact with the bottom of the sewage pool in a horizontal state, increasing the The contact area between the connection frame 803 and the bottom of the sewage pool, and the material of the connection frame 803 is an elastic material, during the contact process between the connection frame 803 and the bottom of the sewage pool, the extrusion force between the connection frame 803 and the bottom of the sewage pool increases. Large, the lower side of the connection frame 803 is deformed to fit the bottom of the sewage pool, the contact area between the connection frame 803 and the bottom of the sewage pool is increased, and the rectangular support rod 608 is supported. At the same time, the sewage pump is supported, and the first stretching completed A housing 607 and a rectangular support rod 608 support the bottom of the sewage pump. During the working process of the sewage pump, the sewage pump will suck in impurities such as stone particles and vibrate. By supporting the sewage pump, the sewage pump can be kept vertical. In the straight state, avoid the dumping of the sewage pump, resulting in a reduction in the final pumping capacity of the sewage pump.

After the sewage pump is fixed, start to pump the sewage in the sewage pool, the operator electrifies the wire 3, the submersible motor 2 starts to drive the motor shaft 4 to rotate, the motor shaft 4 drives the impeller 5 to rotate, and the impeller 5 rotates at a high speed to remove the sewage in the sewage pool The pumping casing 1 is drawn from the water inlet 101, and then discharged from the water pipe from the water outlet 102. During the process of pumping sewage by this sewage pump, since the sewage contains impurities, the impurities in the sewage will also be extracted. When the net 902 contacts, the impurities are intercepted by the filter net 902, preventing the impurities from entering the sewage pump and affecting the normal operation of the sewage pump. Affect the water intake of this drainage pump, and indirectly affect the drainage efficiency of this sewage pump. Therefore, when the impurities on the filter screen 902 accumulate to a certain amount (when affecting the water intake of the sewage pump), it is necessary to filter the impurities on the filter screen 902. clean up.

The specific operations are as follows: in the initial state, the second spring 904 is in a compressed state, and the draft produced by the impeller 5 is a constant value. When impurities are attached to the filter screen 902, the impurities block the mesh of the filter screen 902, increasing the The area of the filter screen 902 is subject to the pumping force, so with the accumulation of impurities, the filter screen 902 will move upward, the filter screen 902 drives the ring 901 to move upward, the second spring 904 is compressed, and the ring 901 drives three push rods 905 Moving upwards, the pressure in the three cylindrical cavities 103 and the annular cavity 104 increases. Since the arc-shaped scraper 912 is limited by the filter screen 902 and cannot move to the left, the piston disc 910 cannot move to the left. The pressure in the cavity 104, the air pressure in the annular cavity 104 pushes the sealing column 907 to move to the right, and the pressure on the right side of the sealing column 907 and the right side of the piston disc 910 in the air guide sleeve 908 increases, when the sealing column 907 and the first When the limit rod 1002 contacts, the sealing column 907 continues to move to the right, and the inclined surface on the lower side of the round platform of the seal column 907 squeezes the first limit rod 1002, and the first limit rod 1002 drives the folding rod 1003 to move downward, and the second The four springs 1004 are stretched, and when the limiting hole of the sealing column 907 is aligned with the first limiting rod 1002, the fourth spring 1004 resets, and the fourth spring 1004 drives the first limiting rod 1002 to move upward through the folding rod 1003, The upper end of the first limiting rod 1002 is inserted into the limiting hole of the sealing column 907 to limit it, and the pressure on the right side of the sealing column 907 and the right side of the piston disc 910 is high pressure.

After the sealing column 907 is limited, the filter screen 902 continues to move upward, and the pressure in the cylindrical cavity 103 and the annular cavity 104 continues to increase. , the limit of the arc-shaped scraper 912 is lifted, the pressure of the high-pressure gas on the right side of the sealing column 907 and the right side of the piston disc 910 is released, and the piston disc 910 is pushed to move to the left, and the sewage on the left side of the piston disc 910 is discharged from the air guide sleeve 908 The through hole of the piston plate 910 drives the limit housing 911 to move to the left through the second slide rod 909, and the limit housing 911 drives the arc-shaped scraper 912 and the third spring 913 to move to the left, and the arc-shaped scraper 912 moves to the left. The upper side is in contact with the lower side of the filter screen 902, and the arc-shaped scraper 912 scrapes off the impurities of the filter screen 902. Since the left side of the arc-shaped scraper 912 is a semicircular arc, the arc-shaped scraper 912 will scrape off the scraped impurities. Gather to the middle of its left side, the impurity that is pushed accumulates on the left side of arc-shaped scraper 912, and the material of arc-shaped scraper 912 is elastic material, has increased the upper side of arc-shaped scraper 912 and filter net 902 The contact area between the sides makes the arc-shaped scraper 912 close to the lower side of the filter screen 902, ensuring that the arc-shaped scraper 912 scrapes off all impurities.

When the arc-shaped scraper 912 scrapes off the impurities attached to the lower side of the filter screen 902, the mesh holes on the right side of the lower side of the filter screen 902 are no longer blocked, and the suction force on the filter screen 902 is reduced. Therefore, The high pressure in the cylindrical cavity 103, the annular cavity 104 and the left side of the sealing column 907 is released, and at the same time the second spring 904 resets, the second spring 904 drives the ring 901 to move downward, and the ring 901 drives three push rods 905 Move down with the filter screen 902, squeeze the arc scraper 912 when the filter screen 902 moves downward, the arc scraper 912 moves downward synchronously with the filter screen 902, and the arc scraper 912 moves to the left on the impurities on the filter screen 902 During the scraping process, the right side of the arc-shaped scraper 912 is long enough, the limit housing 911 will not move to the lower side of the filter screen 902, and will not affect the downward movement of the filter screen 902, the third spring 913 is compressed, During the downward movement of the three push rods 905, the pressure on the left side of the three cylindrical cavities 103, the annular cavities 104 and the sealing column 907 decreases simultaneously and becomes negative pressure gradually. When the lower side of the filter screen 902 is in contact with the When the left end of folding bar 1003 touches, filter screen 902 continues to move downwards and drives folding bar 1003 to move downwards, and folding bar 1003 drives first limit bar 1002 to move downwards, and the 4th spring 1004 is stretched, and the first The upper end of the limiting rod 1002 gradually moves out from the limiting hole of the sealing column 907, and when the upper end of the first limiting rod 1002 moves out of the limiting hole of the sealing column 907, the first limiting rod 1002 releases the pressure on the sealing column 907. limit, the filter screen 902 returns to the initial state and no longer moves downward.

All the impurities on the side are scraped off to prevent the filter 902 from being blocked by impurities and reduce the water intake of sewage, thereby affecting the pumping efficiency of the sewage pump. The piston plate 910 drives the arc-shaped scraper through the second sliding rod 909 and the limit housing 911 912 moves to the right, when the arc scraper 912 is no longer in contact with the lower side of the filter screen 902, the third spring 913 resets and drives the arc scraper 912 to move upward, when the right side of the arc scraper 912 is located in the limit housing When the body 911 is on the upper side of the T-shaped chute, the reset of the curved scraper 912 is completed. Every time the amount of impurities attached to the filter screen 902 reaches a certain value, the impurities are scraped off by the curved scraper 912 to ensure the normal operation of the sewage pump. water volume.

During the working process of the drainage pump, if the drainage pump vibrates, since the upper side of the rectangular support rod 608 in the first housing 607 is gas, the drainage pump buffers its own vibration through air pressure and disperses the vibration to four rectangular The support rod 608 ensures the stability of the operation of the drainage pump. When the sewage in the sewage pool is pumped out, the operator cuts off the power of the wire 3 and takes the sewage pump out of the sewage pool through a rope, and then the operator presses three U-shaped Rod 704, the three U-shaped rods 704 are close to the pumping housing 1, and the three first springs 705 are compressed. When the three U-shaped rods 704 release the limit to the adjacent first sliding rod 602, the first sliding rod 602 Moving down, the rectangular support rod 608 enters the first casing 607, and the lower end of the first casing 607 gradually approaches the pumping casing 1, and the operator resets the drainage pump, and the drainage pump is used.
