Abstract
Description
Technical Field
[0001] This utility model relates to the field of submersible pump technology, specifically a submersible pump with an anti-clogging structure. Background Technology
[0002] A submersible pump is a vertical centrifugal pump whose core feature is that the pump body and impeller are immersed in the liquid. It is suitable for conveying various liquids, including clean water, sewage, corrosive liquids, and media containing particles.
[0003] Since submersible pumps are mainly used to lift liquids to a certain height, they all have a discharge pipe with a bend. Because the flow velocity is relatively slow at the bend of the pipe, and it is also the area where the liquid level is lifted, blockages or impurities are prone to occur at this point. Moreover, because the bend is located deep in the pipe, it is difficult to clean.
[0004] Therefore, we propose a submersible pump with an anti-clogging structure, which is beneficial for concentrating and blocking impurities in the liquid at the bend, and can also clean up the impurities blocked at the bend. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a submersible pump with an anti-clogging structure to solve the problems existing in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a submersible pump with an anti-clogging structure, comprising a motor and a support pipe, wherein the motor is connected to the support pipe via a coupling below, and an impeller assembly is connected to the other end of the support pipe, and a liquid outlet pipe is connected to one side of the impeller assembly, characterized in that: an anti-clogging component is provided at the bend of the liquid outlet pipe;
[0007] An auxiliary motor is installed on the outer wall of the three-way pipe of the anti-clogging component. The shaft of the auxiliary motor is connected to an electric push rod through a convex-concave engagement structure. The power supply line of the electric push rod is connected to an electric slip ring. The movable rod of the electric push rod passes through the side wall of the three-way pipe, and its end is connected to a blocking shell located inside the left pipe of the three-way pipe. A blocking filter screen is installed inside the blocking shell. The blocking shell engages with the left pipe of the three-way pipe. A semi-arc scraper is connected to the front end of the blocking shell.
[0008] Furthermore: the lower pipe of the tee is threaded with a sealing ring, and a guide block is provided at the lower pipe opening of the tee above the sealing ring. A sealing plate is provided inside the sealing ring, and the bottom of the guide block is engaged with the protrusion on the sealing plate through a bearing. A cleaning cover is threadedly connected to the bottom of the sealing ring.
[0009] Furthermore: the width of the guide block occupies two-thirds of the diameter of the lower pipe opening, and the rotation of the closing ring causes the closing plate to rotate around the bearing as the center point, thus closing the lower pipe of the tee together with the guide block.
[0010] Furthermore: when the sealing plate together with the guide block closes the lower pipe of the tee pipe, the tee pipe and the outer wall of the sealing ring are respectively equipped with ring clamps on the same side, and a pin is inserted between the two sets of ring clamps.
[0011] Furthermore: the auxiliary motor starts after the electric motor stops, and the start of the auxiliary motor causes the scraper to rotate from the top of the pipe to the bottom of the pipe and retract the electric push rod.
[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0013] 1) The submersible pump with anti-clogging structure of this utility model, through the setting of an auxiliary motor, an electric push rod and a blocking shell, the electric push rod is activated to make the blocking shell engage with the left pipe of the three-way pipe. The blocking filter screen of the blocking shell filters the impurities in the liquid, causing the impurities to accumulate below the filter screen. When the motor stops, the hydraulic pressure of the liquid disappears, the auxiliary motor is activated to make the scraper rotate from the top of the pipe to the bottom of the pipe, and then the electric push rod is activated to retract, and the scraper scrapes the impurities settled at the bottom of the pipe into the cleaning cover. The telescopic rod reciprocates in a certain stroke to shake off the impurities adhering to the filter screen, which helps to concentrate and block the impurities in the liquid at the bend, and at the same time, it can clean the impurities blocked at the bend.
[0014] 2) The submersible pump with anti-clogging structure of this utility model rotates the sealing ring so that the sealing plate rotates around the bearing as the center point, and together with the guide block, seals the lower pipe of the three-way pipe. When rotating, the cleaning cover is removed to clean the precipitated medium, which facilitates the cleaning of the precipitated medium and prevents blockage. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The structures involved in this utility model are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Example:
[0024] Please see Figure 1-6 This utility model provides a technical solution: a submersible pump with an anti-clogging structure, including a motor 1 and a support pipe 3. The motor 1 is connected to the support pipe 3 via a coupling 2. The other end of the support pipe 3 is connected to an impeller assembly 4. One side of the impeller assembly 4 is connected to an outlet pipe 5. An anti-clogging component 6 is provided at the bend of the outlet pipe 5.
[0025] An auxiliary motor 62 is installed on the outer wall of the three-way pipe 61 of the anti-blocking component 6. The shaft of the auxiliary motor 62 is connected to an electric push rod 621 through a concave-convex interlocking structure. The power supply line of the electric push rod 621 is connected to an electric slip ring 625. The movable rod of the electric push rod 621 passes through the side wall of the three-way pipe 61 and is connected to a blocking shell 622 located in the left tube of the three-way pipe 61. The electric slip ring 625 is based on contact transmission to achieve free rotation electrical connection. The external power supply circuit is connected to the electric slip ring 625. The power supply line of the electric push rod 621 is connected to the electric slip ring 625, so that the electric push rod 621 maintains power supply during rotation.
[0026] Among them, the electric slip ring 625 adopts a through-hole conductive slip ring 625, and its specific model can be referred to MT. A waterproof sealing ring is set at the point where the electric push rod 621 passes through the three-way pipe 61 to prevent water from overflowing.
[0027] The movable end of the electric push rod 621 is equipped with a blocking shell 622. A blocking filter 623 is installed inside the blocking shell 622. The movable rod of the electric push rod 621 is located inside the three-way pipe 61. The movable rod drives the blocking shell 622 to move left and right. The blocking shell 622 is engaged with the left pipe of the three-way pipe 61. A semi-arc scraper 624 is connected to the front end of the blocking shell 622.
[0028] The lower pipe of the tee pipe 61 is threaded with a sealing ring 63. A guide block 611 is provided at the lower pipe opening of the tee pipe 61 located above the sealing ring 63. A sealing plate 631 is provided inside the sealing ring 63. The bottom of the guide block 611 is engaged with the protrusion on the sealing plate 631 through a bearing 632. A cleaning cover 64 is threadedly connected to the bottom of the sealing ring 63.
[0029] The guide block 611 has a width that occupies two-thirds of the diameter of the lower pipe opening. The rotation of the closing ring 63 causes the closing plate 631 to rotate around the bearing 632 as the center point, and together with the guide block 611, it closes the lower pipe of the tee pipe 61.
[0030] The rotation of the closing ring 63 causes the closing plate 631 to rotate around the bearing 632, and together with the guide block 611, it seals the lower pipe of the three-way pipe 61. The rotation removes the cleaning cover 64 to clean the precipitated medium, which facilitates the cleaning of the precipitated medium and prevents blockage.
[0031] When the sealing plate 631, together with the guide block 611, seals the lower pipe of the tee pipe 61, the outer walls of the tee pipe 61 and the sealing ring 63 are respectively equipped with ring clamps, and the two sets of ring clamps are located on the same side, with a pin 65 inserted between the two sets of ring clamps.
[0032] When the sealing plate 631, together with the guide block 611, seals the lower pipe of the tee pipe 61, the outer walls of the tee pipe 61 and the sealing ring 63 are respectively equipped with ring clamps, and the two sets of ring clamps are located on the same side, with a pin 65 inserted between the two sets of ring clamps.
[0033] Before cleaning the cleaning cover 64, the closing ring 63 needs to be rotated first. By rotating the closing ring 63, the ring clamps on the outer wall of the tee pipe 61 and the closing ring 63 are on the same side. The pin 65 is inserted into the two sets of ring clamps to restrict the rotation of the closing ring 63. Then the cleaning cover 64 is rotated.
[0034] The auxiliary motor 62 starts after the motor 1 stops. The start of the auxiliary motor 62 causes the scraper 624 to rotate from the top of the pipe to the bottom of the pipe and retract the electric push rod 621.
[0035] By activating the electric push rod 621, the blocking shell 622 engages with the left pipe of the three-way pipe 61, and the submersible pump is started normally. The coupling 2 is connected through the shaft of the motor 1, and the impeller in the impeller assembly 4 is connected through the support pipe 3. Under the action of the centrifugal force generated by the rotation of the impeller, the liquid flows from the bottom through the liquid outlet pipe 5 to achieve liquid level rise.
[0036] The liquid passes through the filter screen 623 at the bend of the outlet pipe 5 to filter impurities.
[0037] The anti-clogging component 6 needs to be cleaned regularly;
[0038] Impurities in the liquid are filtered by the filter screen 623 of the blocking shell 622, causing the impurities to accumulate below the filter screen. When the motor 1 stops, the hydraulic pressure of the liquid disappears, the auxiliary motor 62 is started, and the scraper 624 rotates from the top of the pipe to the bottom of the pipe. Then, the electric push rod 621 is started to retract, and the scraper 624 scrapes the impurities settled at the bottom of the pipe and enters the cleaning cover 64. The telescopic rod reciprocates in a certain stroke to shake off the impurities adhering to the filter screen.
[0039] First, rotate the closing ring 63. By rotating the closing ring 63, the ring clamps on the outer wall of the tee pipe 61 and the closing ring 63 are on the same side. Insert the pin 65 into the two sets of ring clamps to restrict the rotation of the closing ring 63. Then, rotate the cleaning cover 64.
