Description

Technical Field

[0001] The utility model relates to a pump installation device, in particular to a device used for installing a slurry pump, and belongs to the technical field of pump installation. Background Art

[0002] A slurry pump is a machine that increases the energy of a solid-liquid mixed medium by means of centrifugal force, and converts electrical energy into kinetic energy and potential energy of the medium. Slurry pumps are widely used in non-ferrous and ferrous metal mining production, and are mainly used to transport slurry containing solid particles.

[0003] Existing slurry pumps are generally configured with two units, sharing a slurry pool, one of which is working and the other is spare. During the manufacturing process, the process is adjusted and the model of the slurry pump needs to be changed. However, the center line of the slurry pump inlet is not necessarily concentric with the center line of the embedded feeding steel pipe, and production cannot be stopped to drain the slurry in the slurry pool and replace the embedded feeding steel pipe embedded in the concrete slurry pool. This makes it difficult to install a new pump.

[0004] At present, the patent CN 207647764U slurry pump inlet connection assembly includes an ore conveying pipe connected to the ore box, one end of which is connected to the ore conveying pipe through a flange, and the other end of which is connected to the slurry pump inlet connection pipe of the slurry pump. One end of the slurry pump inlet connection pipe is a round pipe, and the other end is provided with a flange. A groove is opened at the front end of the ore conveying pipe. The wall thickness of the round pipe end of the slurry pump inlet connection pipe is the same as the thickness of the groove. The round pipe end of the slurry pump inlet connection pipe is inserted into the groove and welded to the ore conveying pipe. An expansion joint is provided between the slurry pump inlet connection pipe and the slurry pump. One end of the expansion joint is fixedly connected to the flange of the slurry pump inlet connection pipe through a flange, and the other end of the expansion joint is fixedly connected to the flange of the slurry pump through a flange. The assembly turns the slurry flushing part into an inlet connection. The whole pipe and expansion joint are connected. At the same time, since the expansion joint is made of wear-resistant rubber material, the problem of short service life of the inlet connecting pipe of the slurry pump is effectively solved, the operation rate of the slurry pump is improved, and the replacement is convenient. Even if the rubber weight is not tightly blocked, it can be replaced, ensuring the normal service life of the inlet connecting pipe. However, this component only makes the connection and replacement of the inlet pipe and the slurry pump convenient. The inlet pipe adds a wear-resistant layer, which can appropriately extend the service life. A gate valve is added to the right flange end of the connecting pipe. When the pump is working, the gate valve is in a fully open state; when maintenance is required, it is in a fully closed state. The gate valve is not used to adjust the flow, which is better; but it cannot solve the installation problem of different models and different centerline heights.

[0005] Therefore, developing a device for installing a slurry pump that can overcome the above defects has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by the utility model is that when replacing the pump, the center line of the pump is not concentric with the center line of the embedded pipe, and it is difficult to replace the pump without stopping production. The disadvantages of the prior art are overcome and a device for installing a slurry pump is provided. The device can realize rapid installation of the pump and the embedded feeding steel pipe, and is easy to install and disassemble.

[0007] In order to solve the above technical problems, the utility model provides a device for installing a slurry pump, which is arranged between the slurry pump and the slurry pool, and connects the slurry pump with the embedded feeding steel pipe on the slurry pool. The device includes a sealing box, an elastic expansion joint and a connecting pipe. The elastic expansion joint includes a first elastic expansion joint and a second elastic expansion joint. The first elastic expansion joint is arranged on one side of the sealing box, one end of the first elastic expansion joint is connected to the sealing box, and the other end is connected to the embedded feeding steel pipe on the slurry pool. The second elastic expansion joint is arranged on a side of the sealing box away from the first elastic expansion joint, one end of the second elastic expansion joint is connected to the sealing box, and the other end is connected to the slurry pump through the connecting pipe.

[0008] The technical solution further defined in the utility model is:

[0009] Furthermore, in the aforementioned device for installing a slurry pump, a gate valve is also provided on the pre-buried feeding steel pipe.

[0010] Technical effect: The utility model provides a gate valve on the embedded feeding steel pipe. The gate valve is a gate plate of an opening and closing component. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can be controlled to be fully opened and fully closed, which is convenient for replacement or maintenance of parts during production.

[0011] In the aforementioned device for installing a slurry pump, the center lines of the pre-buried feeding steel pipe and the slurry pump feed port are inconsistent.

[0015] In the aforementioned device for installing a slurry pump, the center lines of the pre-buried feeding steel pipe and the slurry pump feed port are inconsistent. When the vertical plane of the center line of the pre-buried feeding steel pipe and the first elastic expansion device is located behind the vertical plane of the center line of the connecting pipe and the slurry pump feed port, the center line of the slurry pump and the second elastic expansion device is located to the upper left of the center line of the pre-buried feeding steel pipe and the first elastic expansion device.

[0016] Technical effect: the center lines of different pump models may be inconsistent. When the height of the center line of the slurry pump feed port is higher than the center line of the embedded feeding steel pipe, the vertical plane of the center line is not in the same plane, and the safety distance on the right side of the slurry pump (looking from the pump drive end to the feed port) is insufficient, the center line of the pump inlet should be placed on the upper left of the center line of the embedded pipe to facilitate smooth docking and replacement.

[0019] In the aforementioned device for installing a slurry pump, the center lines of the pre-buried feeding steel pipe and the slurry pump feed port are inconsistent. When the vertical plane of the center line of the pre-buried feeding steel pipe and the first elastic expansion device is located in front of the vertical plane of the connecting pipe and the center line of the slurry pump feed port, the center line of the slurry pump and the second elastic expansion device is located to the upper right of the center line of the pre-buried feeding steel pipe and the first elastic expansion device.

[0020] Technical effect: the center lines of different pump models may be inconsistent. When the height of the center line of the slurry pump feed port is higher than the center line of the embedded feeding steel pipe, the vertical plane of the center line is not in the same plane, and the safety distance on the left side of the slurry pump (looking from the pump drive end to the feed port) is insufficient, the center line of the pump inlet should be placed to the upper right of the center line of the embedded pipe to facilitate smooth docking and replacement.

Different positions are set according to the model of the pump. The pump can be connected to the embedded feeding steel pipe only by adjusting the connection position of the second elastic expansion joint on the sealing box. There is no need to stop production or replace the embedded feeding steel pipe, which is convenient for quick replacement of the connection.
