Description

Technical Field

[0001] The utility model relates to the technical field of electric pole production, in particular to the field of centrifuge cleaning, and specifically refers to an automatic washing system for centrifugal residual slurry of electric poles. Background Art

[0002] Concrete poles are widely used in power overhead transmission and transformation lines, railway contact network pillars, broadcasting and communication, municipal lighting and other projects due to their irreplaceable advantages such as low cost, convenient construction, long service life and maintenance-free. Since the first square solid cement pole mold was produced in my country in 1924, my country's cement concrete pole mold has a history of more than 100 years. At present, my country has become the country with the largest number of concrete pole molds in the world.

[0003] Generally, concrete poles are made of steel bars and concrete as the main materials, using a centrifugal molding process and steam curing to form a precast concrete component. During the centrifugal treatment process, a large amount of residual slurry will be produced, the total amount of which can reach 20%-30% of the concrete mixing water. Its main components are water, cement, gravel particles, etc.

[0004] In order to ensure uniform quality of the cast poles and no excess slurry remains, the excess slurry needs to be poured out. The poured excess slurry will be collected and reused for the purpose of cost saving and environmental protection. In the prior art, the excess slurry is generally cleaned out of the centrifuge by a natural slurry discharge method. The crane lifts the tip of the pole mold for dumping. The excess slurry will flow out under natural gravity and then be collected in a slurry storage tank through the cement slurry flow channel and transported to the mixer for recycling. During the dumping process, the cement slurry will splash everywhere, which is difficult to collect and pollutes the environment. Most of the current methods use water pipes for manual flushing, which is not only unsafe, but also pollutes the environment and is difficult to clean. It is also easy to dirty the operator's clothes, which reduces the comfort of the employees. Utility Model Content

In the setting of this optimization scheme, the motor can drive the limit mechanism to limit the revolving door.

The setting of this optimization scheme is convenient for moving the slurry receiving vehicle, and the slurry receiving vehicle can be moved according to the requirements of different types of rod molds, and the operation is convenient.

[0012] As an optimization, a valve is installed on the water supply pipe, and the valve is controlled by a solenoid valve, and the solenoid valve is electrically connected to the centrifugal system. The setting of this optimization scheme can control the opening and closing of the valve by the solenoid valve, thereby controlling the water supply of the water supply pipe.

[0033] The limiting mechanism 39 includes a shell 391 installed on the retaining wall 31, the shell 391 extends in the front-to-back direction, the shell 391 is hollow, the left end face of the shell 391 is fixedly connected to the right end face of the retaining wall, and a limiting block 392 is slidably connected inside the shell, the limiting block 392 extends in the front-to-back direction, and the limiting block extends to the revolving door 36.

The intermediate relay and the time relay are respectively electrically connected to the centrifuge frequency converter and the variable frequency booster pump. The intermediate relay is electrically connected to the warning light.

[0037] During use of this embodiment, when the centrifuge stops running, the auxiliary normally open contact of the centrifuge inverter is disconnected, the intermediate relay loses power, the normally closed contact loses power and closes, the first time relay is turned on and starts timing, when the set waiting time is reached, the first time relay connects to the second time relay, the second time breaker is energized and closed, the solenoid valve is turned on, the solenoid valve opens the valve 33, the variable frequency booster pump automatically increases pressure, water flows into the water supply pipe 321, and is sprayed out through the nozzle 324, thereby flushing the residual slurry, and when the second time relay reaches the set flushing time, the valve 33 is automatically closed to stop flushing.

[0038] When the centrifuge stops running, the crane lifts the tip of the rod mold 1, and the root end of the rod mold 1 is always located in the slurry receiving vehicle 34. Under the lifting of the crane, the inclination angle of the pole gradually increases, and the residual slurry flows from the tip of the rod mold 1 into the slurry receiving vehicle 34, and the splashed residual slurry falls to the ground. When the nozzle 342 sprays water, the water flow flushes the residual slurry on the ground, and the residual slurry in the retaining wall 31 flows into the slurry flow channel 4 and finally converges into the slurry storage tank 5.

[0039] When the centrifuge is running, the intermediate relay turns on the warning light 37, and the warning light 37 lights up red to indicate that the centrifuge is operating, warning the operator not to open the door and approach; when the centrifuge stops running and the nozzle 324 sprays water, the warning light lights up yellow to indicate that the cleaning device is operating, warning the operator to avoid opening the door as much as possible; when both the cleaning device and the centrifuge stop operating, the warning light 37 lights up green, and the operator can open the door to operate.

[0040] When the centrifuge is working, the limit block 392 prevents the rotating door from opening. When the centrifuge and the cleaning device stop working, the motor 38 rotates to drive the connecting shaft 394 to rotate, and the connecting shaft drives the gear 393 to rotate. The gear engages with the rack, thereby driving the limit block 392 to move left and right. The limit block 392 is retracted into the shell 391, and the rotating door can be opened. The motor is electrically connected to a control button, and the control button can control the rotation of the motor. In special circumstances, the control button can be used to control the rotation of the motor to retract the limit block, thereby opening the rotating door.
