Description

Technical Field

[0001] This utility model relates to the field of sand pumping equipment, and in particular to a sand pumping device that facilitates internal cleaning. Background Technology

[0002] A sand dredging device is a mechanical device used to extract, transport, or process sand and gravel mixtures. It is widely used in water conservancy, construction, mining, environmental protection, and other fields. It uses centrifugal pumps or slurry pumps to generate negative pressure, sucking in the sand-water mixture through pipelines and transporting it to a designated location. Sand dredging devices are an indispensable piece of equipment in modern engineering, and their value is reflected in resource development, environmental management, and infrastructure construction.

[0003] Existing sand-dredging devices suffer from slurry buildup on the inner walls during prolonged operation, hindering slurry movement within the pipes. Furthermore, prolonged operation leads to the formation of stubborn slurry deposits on the pipe walls, potentially causing blockages. Internal cleaning is also difficult, requiring complete shutdown and specialized cleaning equipment, resulting in low efficiency and high costs. Therefore, this paper proposes a sand-dredging device with convenient internal cleaning to address these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems in the existing technology and provide a sand-dredging device that facilitates internal cleaning.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A sand-dredging device for convenient internal cleaning includes:

[0007] The sand inlet pipe is cylindrical. A sand extraction pipe connected to the sand inlet pipe is welded to the top of one side of the sand inlet pipe. A circular top sealing plate is installed at the top of the sand inlet pipe, and a motor is installed at the top of the top sealing plate. A circular bottom sealing plate is installed at the bottom of the sand inlet pipe, and a grid hole that runs through the top and bottom is opened on the bottom sealing plate.

[0008] The rotating shaft is rotatably mounted at the center of the top sealing plate and the center of the bottom sealing plate, respectively. The top of the rotating shaft is connected to the motor shaft of the motor through a coupling. The side wall of the rotating shaft is provided with multiple side agitators for agitating the mortar in the sand inlet pipe, a set of scraper mechanisms for scraping the inner wall of the sand inlet pipe, and a set of cleaning brush mechanisms for scrubbing the inner wall of the sand inlet pipe.

[0009] The side agitator includes a fan-shaped mounting block and an agitator rod. The mounting block is located at one end of the agitator rod. The mounting block and the agitator rod are integrally formed. The thickness of the agitator rod gradually decreases from the end closer to the mounting block to the end farther away from the mounting block. The mounting block is mounted on a rotating shaft with screws.

[0010] The scraper mechanism includes a crossbar, a mounting plate, and a scraper. One end of the crossbar is welded to the side wall of the rotating shaft. The mounting plate is welded to the end of the crossbar away from the rotating shaft. The scraper is fixed to the side of the mounting plate away from the rotating shaft and is perpendicular to the mounting plate.

[0011] The cleaning brush mechanism includes a second crossbar, a second mounting plate, and a bristle bundle. One end of the second crossbar is welded to the side wall of the rotating shaft. The second mounting plate is welded to the end of the second crossbar away from the rotating shaft. Several bristle holes are opened on the side of the second mounting plate away from the rotating shaft. The middle part of the bristle bundle is tied with steel wire and nailed into the bristle holes.

[0012] The bottom end of the bottom sealing plate is fixed with multiple fan-shaped support plates, which are arranged in a circular array with the central axis of the bottom sealing plate as the center.

[0013] The rotating shaft has a mounting ring installed at its bottom, and two horizontal agitators arranged symmetrically about the mounting ring are fixed to the outer side wall of the mounting ring. The horizontal agitators are comb-shaped.

[0014] The top sealing plate and the bottom sealing plate are respectively provided with an upwardly protruding bearing mounting seat. Each bearing mounting seat is equipped with a waterproof sealing bearing. The two ends of the rotating shaft are respectively interference-fitted into the inner rings of the two waterproof sealing bearings.

[0015] The central axis of the sand extraction pipe is perpendicular to the central axis of the sand inlet pipe.

[0016] The beneficial effects of this utility model are:

[0017] The motor drives the shaft to rotate. When the mortar enters the sand inlet pipe, the side agitator stirs and agitates the mortar, improving its fluidity and reducing the risk of blockage due to excessive resistance. At the same time, the rotating scraper mechanism scrapes off the mortar adhering to the inner wall of the sand inlet pipe, and the rotating cleaning brush mechanism cleans the inner wall of the sand inlet pipe, keeping it clean. This eliminates the need for regular cleaning by operators and reduces their workload.

[0018] Larger stones and debris are blocked by the grid holes on the bottom sealing plate to prevent clogging of the sand inlet pipe. A horizontal agitator rotates below the grid holes to agitate them, preventing mortar from accumulating below the grid holes and causing blockage. This improves the stability of the sand feeding through the grid holes during sand extraction. Furthermore, the support plate increases the space below the grid holes during sand extraction, reducing the possibility of the grid holes touching the bottom and causing blockage, thus improving the stability of sand feeding.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figures 1 to 10 As shown, a sand-dredging device for convenient internal cleaning includes a cylindrical sand inlet pipe 1 and a rotating shaft 6.

[0033] A sand extraction pipe 2, which is connected to the sand inlet pipe 1, is welded to the top of one side of the sand inlet pipe 1. The central axis of the sand extraction pipe 2 is perpendicular to the central axis of the sand inlet pipe 1.

[0034] A circular top sealing plate 3 is installed at the top of the sand inlet pipe 1, and a circular bottom sealing plate 5 is installed at the bottom of the sand inlet pipe 1. The two ends of the rotating shaft 6 are respectively rotatably installed at the center of the top sealing plate 3 and the center of the bottom sealing plate 5. The top sealing plate 3, the bottom sealing plate 5, the sand inlet pipe 1, and the rotating shaft 6 are coaxial. Specifically, an upwardly protruding bearing mounting seat 11 is set at the center of the top sealing plate 3 and the center of the bottom sealing plate 5, and a waterproof sealed bearing 12 is installed in each bearing mounting seat 11. The two ends of the rotating shaft 6 are respectively interference-fitted into the inner rings of the two waterproof sealed bearings 12.

[0035] The top of the top sealing plate 3 is equipped with a motor 4. The top of the rotating shaft 6 is connected to the motor shaft of the motor 4 through a coupling 13. The specific installation structure of the motor 4 is as follows: the top of the top sealing plate 3 is welded with four motor support columns 301 arranged in a rectangular array. The motor 4 is fixed to the top of the motor support columns 301 with bolts that are screwed into the motor support columns 301.

[0036] The bottom sealing plate 5 has a grid hole 501 that runs vertically through it. When the mortar is sucked in along the bottom of the sand inlet pipe 1, it will first pass through the grid hole 501 to block larger stones and debris, preventing blockage of the sand inlet pipe and improving the fluidity of the mortar entering the sand inlet pipe 1.

[0037] Multiple side agitators 7 are provided on the side wall of the rotating shaft 6 to agitate the mortar in the sand inlet pipe 1. The multiple side agitators 7 are arranged in a spiral shape on the outside of the rotating shaft 6.

[0038] The side agitator 7 includes a fan-shaped mounting block 701 and an agitator rod 702. The mounting block 701 is located at one end of the agitator rod 702. The mounting block 701 and the agitator rod 702 are integrally formed. The thickness of the agitator rod 702 gradually decreases from the end closer to the mounting block 701 to the end farther away from the mounting block 701. The mounting block 701 is mounted on the rotating shaft 6 with screws.

[0039] When the mortar enters the sand inlet pipe 1, the motor 4 is started, and the rotating shaft 6 is driven to rotate. The rotation of the rotating shaft 6 in the sand inlet pipe 1 will drive the side agitator 7 to rotate. The side agitator 7 will stir and agitate the mortar entering the sand inlet pipe 1, improve the fluidity of the mortar after entering the sand inlet pipe 1, and reduce the situation of blockage caused by excessive resistance in the sand inlet pipe 1.

[0040] A scraper mechanism 8 for scraping the inner wall of the sand inlet pipe 1 is provided on the side wall of the rotating shaft 6. The scraper mechanism 8 includes a crossbar 801, a mounting plate 802, and a scraper 803. One end of the crossbar 801 is welded to the side wall of the rotating shaft 6 and is perpendicular to the rotating shaft 6. The mounting plate 802 is welded to the end of the crossbar 801 away from the rotating shaft 6 and is parallel to the rotating shaft 6. The scraper 803 is fixed to the side of the mounting plate 802 away from the rotating shaft 6 and is perpendicular to the mounting plate 802. A gap of 0.5mm is reserved between the scraper 803 and the inner wall of the sand inlet pipe 1.

[0041] When motor 4 drives shaft 6 to rotate, shaft 6 simultaneously drives crossbar 801 to rotate. Crossbar 801 drives mounting plate 802 to rotate along the inner wall of sand inlet pipe 1. Mounting plate 802 drives scraper 803 to rotate along the inner wall of sand inlet pipe 1. The rotating scraper 803 scrapes away the mortar generated on the inner wall of sand inlet pipe 1, cleaning the inner wall of sand inlet pipe 1 and maintaining its cleanliness. This eliminates the need for regular cleaning by operators, reducing their workload.

[0042] A set of cleaning brush mechanism 9 is provided on the side wall of the rotating shaft 6 to scrub the inner wall of the sand inlet pipe 1.

[0043] The cleaning brush mechanism 9 includes a second crossbar 901, a second mounting plate 902, and a bristle bundle 903. One end of the second crossbar 901 is welded to the side wall of the rotating shaft 6, and the second crossbar 901 is perpendicular to the rotating shaft 6. The second mounting plate 902 is welded to the end of the second crossbar 901 away from the rotating shaft 6, and the second mounting plate 902 is parallel to the rotating shaft 6. Several bristle holes 904 are opened on the side of the second mounting plate 902 away from the rotating shaft 6. The central axis of the bristle hole 904 is perpendicular to the rotating shaft. The middle part of the bristle bundle 903 is tied with steel wire and nailed into the bristle hole 904. The bristle bundle 903 abuts against the inner side wall of the sand inlet pipe 1.

[0044] When motor 4 drives shaft 6 to rotate, the rotating shaft 6 will simultaneously drive crossbar 901 to rotate. The rotating crossbar 901 will drive mounting plate 902 to rotate along the inner wall of sand inlet pipe 1. The rotating mounting plate 902 will drive brush bristle bundle 903 to rotate along the inner wall of sand inlet pipe 1. The rotating brush bristle bundle 903 will clean the inner wall of sand inlet pipe 1, keeping the inner wall of sand inlet pipe 1 clean and eliminating the need for regular cleaning by operators, thus reducing the workload of operators.

[0045] The scraper mechanism 8 and the cleaning brush mechanism 9 are arranged symmetrically about the rotating shaft.

[0046] Four fan-shaped support plates 502 are fixed to the bottom end of the bottom sealing plate 5. The support plates 502 are arranged in a ring array with the central axis of the bottom sealing plate 5 as the center. By using the support plates 502 at the bottom of the bottom sealing plate 5, the space at the bottom of the bottom sealing plate 5 is increased during sand extraction, the blockage caused by the bottom sealing plate 5 touching the bottom is reduced, and the stability of sand injection is improved.

[0047] A mounting ring 10 is installed at the bottom of the rotating shaft 6. Two horizontal stirring frames 1001 are fixedly attached to the outer wall of the mounting ring 10, which are symmetrically arranged about the mounting ring 10. The horizontal stirring frames 1001 are comb-shaped, and a height difference of 3mm is reserved between the horizontal stirring frames 1001 and the bottom sealing plate 5.

[0048] When the motor 4 drives the rotating shaft 6 to rotate, it will synchronously drive the mounting ring 10 to rotate. The rotating mounting ring 10 will drive the horizontal agitator 1001 to rotate. The horizontal agitator 1001 continuously moves and agitates below the grid hole 501, which prevents the mortar from accumulating below the grid hole 501 and causing blockage of the grid hole 501, thus improving the stability of the feed during sand extraction.

[0049] When the sand pumping device is working, the sand pumping pipe 2 is first connected to the inlet of the external slurry pump using a conveying hose, and one end of the sand inlet pipe 1 is set at the position where sand pumping is required. By starting the external slurry pump, the slurry enters the slurry pump in sequence along the sand inlet pipe 1, the sand pumping pipe 2, and the conveying pipe, and then is discharged from the outlet of the slurry pump using the installed sand discharge hose.

[0050] One end of the delivery hose is fixed to the sand extraction pipe 2 with a cable tie or clamp.

[0051] Alternatively, a connecting flange can be installed on the sand dredging pipe 2, and a connecting flange can be installed at the head of the conveying hose. Then, the two connecting flanges can be connected together with matching bolts and nuts.

[0052] The contents not described in detail in this specification are existing technologies known to those skilled in the art and are not key to this utility model, therefore they will not be elaborated upon.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
