Description

Technical Field

[0001] The utility model relates to the technical field of vertical pumps, in particular to a low-energy-consumption idling scroll flow channel vertical pump. Background Art

[0002] A vertical pump is a type of pump used to transport abrasive, coarse particles, and high-concentration slurries. It does not require any shaft seals or seal water and can operate normally even under conditions of insufficient suction volume. As the name suggests, a vertically placed pump body is suitable for use in limited spaces such as pump room basements and drilling platforms.

[0003] Based on the working principle of the vertical pump, it is necessary to use the start-up of the motor to drive the impeller to rotate to generate centrifugal force. The blades on the impeller suck the liquid from the suction port and push it to the outlet, thereby realizing the transportation of the liquid. Therefore, the work of the impeller directly affects the effect of suction circulation. Therefore, if the circulation effect is not good, it is easy to form a long-term energy consumption phenomenon, which can easily cause unnecessary damage to the impeller. Utility Model Content

[0004] The purpose of the present utility model is to provide a low-energy consumption idle-running scroll flow channel vertical pump, so as to solve the problem proposed in the above background technology that the operation of the impeller directly affects the effect of suction circulation, and if the circulation effect is not good, it is easy to form a long-term energy consumption phenomenon, which is easy to directly cause unnecessary damage to the impeller.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a low-energy consumption idling scroll flow channel vertical pump, comprising a vertical pump body and a drive motor, one side of the vertical pump body being connected to an input port, the other side of the vertical pump body being connected to an output port, a cavity being formed inside the vertical pump body, the cavity being composed of a first input chamber, a vortex chamber, and a first outflow chamber, one side of the first input chamber being connected to the vortex chamber, one side of the vortex chamber being connected to the first outflow chamber, the inner wall of the cavity being coated with an anti-corrosion layer, a first reinforcing rod being fixed inside the shell cavity of the vertical pump body, a diagonal bracing reinforcing rod being fixed to one side of the first reinforcing rod, the first reinforcing rods being evenly distributed inside the shell cavity of the vertical pump body, an arc-shaped mounting plate being fixed to the top and bottom ends of the inner wall of the output port, and a mounting ring plate being mounted on one side of the arc-shaped mounting plate.

[0006] Preferably, one side of the input port is communicated with the interior of the vertical pump body, and one side of the output port is communicated with the interior of the vertical pump body.

[0007] Preferably, the arc-shaped mounting plates are symmetrically distributed about the central axis of the output port, and mounting bolts are evenly distributed between the mounting ring plate and the arc-shaped mounting plates.

[0008] Preferably, a center plate is connected to the middle position inside the mounting ring plate, a connecting rod is fixed between the mounting ring plate and the center plate, a filter is installed inside the mounting ring plate, and disassembly handles are installed at the front and rear ends of one side of the mounting ring plate.

[0009] Preferably, the disassembly handles are symmetrically distributed about the central axis of the mounting ring plate, and the connecting rods are symmetrically distributed about the central axis of the mounting ring plate.

[0010] Preferably, an installation groove is opened inside the center plate, a working motor is installed inside the installation groove, the output end of the working motor is connected to the output shaft, cleaning plates are installed at the top and bottom ends of the output shaft, cleaning brushes are evenly distributed on one side of the cleaning plate, and the cleaning plates are symmetrically distributed about the central axis of the output shaft.

[0011] Preferably, the output end of the driving motor is connected to a transmission rod, the bottom end of the transmission rod is connected to an impeller body, and the outer side wall of the impeller body is evenly distributed with fan blade bodies.

[0012] Preferably, a central noise reduction layer is installed at a middle position inside the impeller body, both ends of the central noise reduction layer are connected with isolation shaping layers, and one end of each of the isolation shaping layers is installed with a first noise reduction layer.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the low-energy consumption idling scroll flow channel vertical pump not only improves the circulation effect, but also improves the output filtering capacity and impeller noise reduction capacity of the vertical pump;

[0014] (1) A flow cavity is formed inside the vertical pump body, and the cavity is composed of a vortex cavity, a first input cavity and a first outflow cavity. When the water is introduced into the input port, it first reaches the inside of the first input cavity, and the size of the first input cavity increases from left to right. Therefore, during suction, the flow channel area is gradually expanded, that is, the diffusion flow channel is used to reduce the speed of the fluid and recover part of the kinetic energy, so as to achieve the purpose of high-efficiency flow field design. At the same time, rotational kinetic energy is generated when the impeller body rotates. After the side of the vortex cavity is connected with the first outflow cavity, the fluid diffuses and is finally discharged at the output port. At this time, since the first reinforcement rod is evenly distributed inside the vertical pump body, and the diagonal reinforcement rod is fixed on the side of the first reinforcement rod, the first reinforcement rod and the diagonal reinforcement rod are used to form a combined reinforcement, thereby reducing the deformation problem caused by the impact of the water flow, and the inner wall of the cavity is coated with an anti-corrosion layer, so the overall anti-corrosion ability is better improved during operation, thereby forming a better circulation effect during operation and improving the overall use strength.

[0015] (2) The connection and installation between the mounting ring plate and the arc-shaped mounting plate are completed by using the mounting bolts, and the connection and installation of the center plate are completed by using the connecting rods. When discharged, the waste is filtered through the filter screen, and then the working motor is started to drive the output shaft to rotate. Therefore, the waste can be rotated synchronously under the connection of the cleaning plate. The surface of the filter screen can be cleaned by using the cleaning brush, and the suspended dust can be discharged from the slag discharge port at the bottom of the output port, thereby improving the overall output filtering capacity during the working process;

[0016] (3) After the driving motor is working, the transmission rod can be driven to rotate. When the transmission rod rotates, the impeller body rotates synchronously. At this time, the fan blade body is used to form a fluid vortex, and the first noise reduction layer, the central noise reduction layer and the isolation shaping layer are distributed in sequence inside the impeller body. With the cooperation of the three, the overall noise reduction processing capability is better achieved. BRIEF DESCRIPTION OF THE DRAWINGS
