Detailed Description
The present invention will be described in detail with reference to the drawings and specific embodiments, wherein prior to describing embodiments of the present invention in detail, the terms and terminology used herein are used to explain the same or similar structures and components with the same names or same reference numbers for illustrative purposes only.
Fig. 1 is a schematic structural diagram of the present invention, a roller body 1 is fixed on equipment and rotates along the axis thereof, the end parts thereof are respectively connected with a water return pipeline 2 and a water inlet pipeline 3 through rotary joints, and the water inlet pipeline 3 is further provided with a water inlet valve 31. During operation inlet valve 31 is in normally open state, and cooling water flows into roller body 1 through inlet channel 3, absorbs the heat of roller body 1 after, flows out from return water pipeline 2.
According to the scheme, the air inlet pipeline 4 is connected to the water return pipeline 2 through the tee joint I41, the air inlet pipeline 4 is provided with the valve 42 for controlling air to flow, and the water return pipeline 2 is provided with the water return valve 21 at the downstream of the tee joint I41 for controlling the opening and closing of the water return pipeline 2. Simultaneously inlet channel 3 with set up an air current branch road 5 between the return water pipeline 2, 5 one end of air current branch road pass through tee bend two 53 with the inlet valve 31 low reaches of inlet channel 3 are connected, the other end pass through tee bend three 51 with return water pipeline 2's return water valve 21 low reaches are connected, still be provided with on the air current branch road 5 and be used for control the branch road valve 52 of air current branch road switching. The cooling roller is further provided with an air storage tank 6 at the upstream of the air inlet valve 42 of the air inlet pipeline 4, and the air storage tank 6 plays a role in stabilizing the air pressure in the air inlet pipeline 4 during work through the buffer effect of the air storage volume of the air storage tank 6.
When the pipeline is blocked, dredging the pipeline by the following operations:
step one, closing the water return valve 21 and the water inlet valve 31, then opening the branch valve 52 and the air inlet valve 42, so that high-pressure air at the air inlet reversely rushes into the cooling roller body 1 along the return pipeline through the tee joint I41, then enters the airflow branch 5 through the water inlet pipeline 3, and finally is released from the water return port. In the process, the high-pressure high-speed airflow reversely impacts the corners, the rotary joints and the like of pipelines which are easy to block, so that impurities deposited and blocked at the positions are peeled off and are discharged from the water return port along with the high-pressure high-speed airflow.
And step two, closing the water return valve 21 and the branch valve 52, then opening the air inlet valve 42 and the water inlet valve 31, wherein the high-pressure air pushes the inlet water flow to retreat because the inlet pressure is higher than the inlet pressure, and simultaneously the high-pressure air is accumulated in the pipeline and the roller body, after the inlet pressure is maintained, the air inlet valve 42 is closed, the water return valve 21 is opened, the pipeline and the high-pressure air in the roller body are released, the pressure of the inlet water head pushed back by the high-pressure air is far higher than the inlet pressure, the high-pressure air quickly passes through the water inlet pipeline 3, the roller body 1 and the water return pipeline 2, and impurities possibly remained and attached to the inner wall of the pipeline are stripped and discharged from the water outlet along with the water flow by the impact of the high-speed water flow and the water hammer effect on the blocking point.
It should be noted that the operation in the first step can already play a role of dredging the pipeline, and the second step can further clean the pipeline on the basis of the operation, so that the time interval between the pipelines which are blocked again is prolonged. The gas storage tank 6 utilizes the buffer of the gas accumulated in the inner cavity of the gas storage tank to avoid the pressure reduction caused by the rapid outflow of the gas when the valve is opened during the work and keep the pressure of the gas impacting the pipeline stable.
Meanwhile, it should be noted that the pipeline used in the method of the first step is one of the preferable schemes of the method, wherein the used airflow branch 5 is the preferable technical feature, the airflow branch plays a role in guiding the pipeline impurities stripped in the dredging process to the water return pipeline 2 in the first step and discharging the impurities from the water return port, and the method can still be used under the condition that the airflow branch 5 is not additionally arranged, and the operation method is the same as the second step.
The above-described embodiments are merely preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
