Description

Technical Field

[0001] The present application relates to the field of urea workshop transportation, and in particular to a urea workshop transportation system. Background Art

[0002] In the urea production process, the transportation of urea solution is a vital link. The traditional urea workshop transportation system usually adopts a direct drive method, that is, the motor is directly connected to the impeller of the centrifugal pump for driving. However, this direct drive method has some problems. First, the direct connection between the motor and the centrifugal pump impeller is prone to cause unstable torque transmission, which in turn affects the working efficiency and stability of the centrifugal pump. Secondly, the direct drive method is inconvenient for the maintenance and replacement of the centrifugal pump impeller because the entire motor and the connection part of the centrifugal pump need to be disassembled.

[0003] Therefore, it is necessary to propose a new urea plant transportation system. Utility Model Content

[0005] This application is implemented through the following technical solutions, specifically:

[0006] A urea workshop transportation system comprises a horizontal centrifugal pump, a base, a motor, a rotating shaft, a gear set and a transmission chamber, wherein the horizontal centrifugal pump is arranged on the base; the transmission chamber is arranged between the horizontal centrifugal pump and the motor; the transmission chamber is provided with the gear set connected with the impeller of the horizontal centrifugal pump and the power output shaft of the motor through the rotating shaft.

[0007] As a preferred technical solution of the present application, the rotating shaft includes: a first rotating shaft and a second rotating shaft, wherein one end of the first rotating shaft is connected to the impeller; and one end of the second rotating shaft is connected to the power output shaft.

[0008] As a preferred technical solution of the present application, the gear set includes: a first gear and a second gear, wherein the first gear is meshed with the second gear; the first gear is connected to the other end of the first rotating shaft; and the second gear is connected to the other end of the second rotating shaft.

[0009] As a preferred technical solution of the present application, the system further includes: a urea solution storage tank and a urea solution delivery pipeline, wherein the urea solution storage tank is connected to the suction port of the horizontal centrifugal pump through the urea solution delivery pipeline.

[0010] As a preferred technical solution of the present application, the motor and the transmission cavity are both arranged on the base.

[0011] As a preferred technical solution of the present application, the horizontal centrifugal pump adopts a horizontal 5-stage structure.

[0012] As a preferred technical solution of the present application, the discharge port of the horizontal centrifugal pump is arranged above the transmission chamber.

[0013] As a preferred technical solution of the present application, one end of the second rotating shaft is connected to the power output shaft via a coupling.

[0014] The beneficial effects of this application are:

[0015] A horizontal centrifugal pump, a motor and a transmission chamber are installed on a base, and the motor drives the impeller of the horizontal centrifugal pump to rotate through the transmission chamber and the gear set, wherein one end of the first rotating shaft is connected to the impeller to drive the impeller to rotate, one end of the second rotating shaft is connected to the power output shaft of the motor to receive the power of the motor, and the gear sets are meshed with each other, the first gear is connected to the other end of the first rotating shaft, and the second gear is connected to the other end of the second rotating shaft. When the motor is running, the power is transmitted to the second rotating shaft through the power output shaft, and then the power is transmitted to the first rotating shaft through the meshing of the second gear and the second gear, thereby driving the impeller to rotate. When the impeller rotates at high speed, the impeller drives the liquid to rotate at high speed, thereby generating centrifugal force to throw the liquid out, and a low pressure will be formed at the center of the impeller, thereby generating a pressure difference, sucking the liquid, and realizing continuous operation. Among them, the horizontal centrifugal pump in the technical solution of this application adopts a 5-stage horizontal centrifugal pump, and multiple impellers can provide higher pressure and flow to meet the needs of urea solution transportation.

[0016] Compared with the traditional vertical high-speed centrifugal pump, the technical solution of the present application can also reduce the maintenance cost of the system, reduce the consumption of system spare parts and improve the safety and stability of the system.
