Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dredging pumps, in particular to a wide-flow-channel high-power dredging pump for dredging and desilting. BACKGROUND

[0002] The dredging pump is a special centrifugal pump designed for dredging, desilting and dredging operations, mainly used for conveying solid-liquid mixed medium containing a large amount of sand, stones, water plants and other solid particles. Its core function is to extract and transport underwater sediments to the designated location through strong suction and lift, and is widely used in channel excavation, port expansion, river regulation, reclamation and other engineering fields, and is indispensable in dredging and desilting.

[0003] In the Chinese patent with publication number CN207018204U, a dredging pump for dredging sand on the seabed is proposed, which comprises a pump body, a pump cover, a support, a bearing bush, a main shaft, an impeller, a bearing support, a bearing end cover, a bearing and a shaft sleeve. The pump body is directly fixed and installed on the pump cover, the support of the pump body supports the bearing, the bottom of the pump body is directly provided with a base, the front end of the pump body is provided with the pump cover, the pump cover is provided with the impeller, the impeller is installed at the front end of the main shaft, the front end of the impeller is fixed with the bearing bush through the fastening bolt, the bearing support is supported on the outer side of the bearing, and the pump cover is provided with the shaft sleeve at the contact position of the pump cover and the main shaft. By changing and optimizing the shape of the flow channel, increasing the arc of the flow channel, more adapting to the internal flowability, reducing the resistance, increasing the passability of the sand and improving the efficiency of the dredging sand; However, in the process of dredging and desilting, the mud contains an indefinite amount of plastic bags and branches. When the dredging pump sucks in these impurities, the plastic bags are easily stuck in the main body of the dredging pump, especially easily twisted on the impeller, thereby affecting the rotation of the impeller. The branches are more likely to be stuck in the pump body, which may directly cause the impeller to be unable to rotate. If the plastic bags and branches are filtered before being sucked in, they are also likely to be stuck in the filter screen, thereby causing the filter screen to be blocked, and the filter screen needs to be cleaned frequently, which seriously affects the efficiency of dredging and desilting.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] To address the technical challenges of reducing congestion, such as... Figures 1-6 As shown, the following preferred technical solutions are provided: A wide-channel, high-power dredging pump includes a pump casing 1, a feeding component 2 disposed on one side of the pump casing 1, and a transmission component 3 disposed on the other side of the pump casing 1. One end of the transmission component 3 is connected to an external motor, and a rotating component 6 is disposed inside the pump casing 1. The other end of the transmission component 3 is connected to the rotating component 6.

[0023] The feeding component 2 includes a feeding pipe 23 disposed on one side of the pump casing 1, and an anti-blocking component 24 disposed inside the feeding pipe 23. The anti-blocking component 24 includes a control valve 241 and a processing component 242 disposed inside the feeding pipe 23. The feeding pipe 23 is connected to the dredging pipeline. The processing component 242 includes a small motor 2421 mounted on the outer surface of the feed pipe 23. An electric telescopic rod 2422 is mounted at the output end of the small motor 2421. One end of the electric telescopic rod 2422 is equipped with an arc-shaped plate 2423 located inside the feed pipe 23. A prismatic rod 2424 and a triangular pyramid 2426 are mounted on one side of the arc-shaped plate 2423. One end of the prismatic rod 2424 is elastically connected to a through rod 2425. During dredging, an external motor is activated, driving the transmission component 3 to rotate, which in turn drives the rotating component 6 to rotate, thereby drawing sludge from the outside into the pump casing 1. After being accelerated by the rotation of the rotating component 6, the sludge is discharged from one side of the pump casing 1. The flow channel width of the pump casing 1 is 450mm, suitable for large-particle solids such as sand and gravel, and silt, adapting to high-concentration, high-flow-rate dredging requirements. When large impurities such as plastic bags or branches appear during the operation, they will block the feed pipe 23. At this time, the control valve 241 is closed briefly, and then the electric telescopic rod 2422 is activated. The telescopic nature of the electric telescopic rod 2422 causes the arc plate 2423 to move downward, so that the triangular cone 2426 can pierce the plastic bag or branch, which can pierce the plastic bag and break the branch, preventing the plastic bag and branch from blocking the feed pipe 23, thereby improving the feeding efficiency and quality of the feed pipe 23. When the mud movement speed in the feed pipe 23 is slow, the small motor 2421 is activated. Its output end drives the arc plate 2423 to rotate 90 degrees and brings the two sets of arc plates 2423 closer to each other, so that they form a spindle shape, which can speed up the movement speed of the mud. After rotating 90 degrees, the side of the through rod 2425 is thinner, which can cut the soil clods in the mud.

[0024] The processing assembly 242 is provided with two groups, the two groups of processing assemblies 242 are oppositely arranged, a penetrating rod 2425 is arranged between the two groups of the edge rods 2424, penetrating holes 2427 are formed in the outer surface of the penetrating rod 2425, a through groove is formed in the inner part of the arc-shaped plate 2423, when the arc-shaped plate 2423 is controlled to move up and down by the electric telescopic rod 2422, the two groups of edge rods 2424 move in opposite directions along the penetrating rod 2425 until the two groups of arc-shaped plates 2423 abut against each other, in the moving process of the two groups of arc-shaped plates 2423, the branches adhered to the surface of the edge rod 2424 or the penetrating rod 2425 can be broken, at the same time, the plastic bag can be tied to the triangular pyramid 2426, so as to prevent the feeding pipe 23 from being blocked due to the large volume of the plastic bag.

[0025] The control valve 241 comprises a baffle plate 2411 arranged in the feeding pipe 23, a connecting branch rod 2412 arranged at the upper end of the baffle plate 2411, and a rotating disc 2414 arranged at the upper end of the connecting branch rod 2412, the outer surface of the connecting branch rod 2412 movably arranged has a pad 2413 connected with the outer surface of the feeding pipe 23, the rotating disc 2414 is rotated, so that the connecting branch rod 2412 is rotated, and then the baffle plate 2411 is rotated, so as to realize the opening and closing of the feeding pipe 23, wherein the rotation of the rotating disc 2414 can be manually rotated or mechanically rotated.

[0026] One end of the feeding pipe 23 is provided with a first flange plate 21, one side of the first flange plate 21 is provided with a clamping block 22, one side of the pump shell 1 is provided with a mounting seat 16, one side of the mounting seat 16 is provided with a second flange plate 17, a clamping groove 18 is formed in the outer surface of the second flange plate 17, the clamping groove 18 is clamped and connected with the clamping block 22, a feeding port 12 is formed in one side of the pump shell 1, the pump shell 1 is connected with the feeding pipe 23 through the feeding port 12, the feeding pipe 23 is connected with the second flange plate 17 through the first flange plate 21, and the clamping block 22 is clamped into the clamping groove 18, so as to ensure the stability of the connection of the feeding pipe 23.

[0027] The upper end of the pump shell 1 is provided with a discharge pipe 11, the first unloading valve 13 is arranged on one side of the discharge pipe 11, the second unloading valve 14 is arranged on the outer surface of the lower end of the pump shell 1, the lower end of the pump shell 1 is provided with a support seat 15, the pump shell 1 can be installed on the ground through the support seat 15, so as to ensure the stability during work, through the rotation of the rotating part 6, the mud outside can be sucked into the inside of the pump shell 1 and discharged from the discharge pipe 11, because the discharge pipe 11 and the bottom end inside the pump shell 1 are prone to be blocked, when they are blocked, the second unloading valve 14 and the first unloading valve 13 can be opened for dredging.

[0028] The rotating component 6 includes a third flange 61 disposed on one side of the pump casing 1 and a back plate 62 disposed inside the pump casing 1. The back plate 62 is connected to the third flange 61 by bolts. An impeller 63 is disposed on one side of the back plate 62, and a mudguard 64 is disposed on one side of the impeller 63. A crushing wheel 631 is disposed between the impeller 63 and the mudguard 64 and is connected to the impeller 63. One end of the transmission component 3 passes through the third flange 61 and the back plate 62 and is connected to the impeller 63. As the transmission component 3 rotates, it drives the impeller 63, the crushing wheel 631 and the mudguard 64 to rotate. As the impeller 63 rotates continuously, it can suck the mud from the outside into the pump casing 1. During the suction process, the mudguard 64 can effectively prevent stones in the mud from directly hitting the impeller 63, and the crushing wheel 631 can crush the mud between the impeller 63 and the mudguard 64, which makes it easier to transport the mud.

[0029] Specifically, during the dredging process, an external motor is started, which drives the transmission component 3 to rotate, which in turn drives the rotating component 6 to rotate, thereby drawing the slurry from the outside into the pump casing 1. After being accelerated by the rotation of the rotating component 6, the slurry is discharged from one side of the pump casing 1. Since the flow channel width of the pump casing 1 is 450mm, it can handle media with large particles such as sand and gravel and silt, and can meet the dredging requirements of high concentration and large flow. During the operation, when plastic bags or branches block the feed pipe 23, the control valve 241 is briefly closed, and then the electric telescopic rod 2422 is activated. Utilizing the telescopic property of the electric telescopic rod 2422, the arc plate 2423 moves downward, causing the triangular cone 2426 to strike the plastic bag or branch. This can secure the plastic bag and break the branch, preventing the plastic bag and branch from blocking the feed pipe 23, thereby improving the feeding efficiency and quality of the feed pipe 23.
