Detailed Description
The utility model is described in further detail below with reference to the drawings and the specific examples.
As shown in fig. 1, the anti-blocking high-pressure water jet sand blasting conveying device of the embodiment comprises a grinding tank 1, a collecting bucket 2, a conveying pump 3 and a spray head, wherein the conveying pump 3 is communicated with a water outlet pipe 4 and a water inlet pipe 5, the water outlet pipe 4 is communicated with a water inlet pipe 6, the top end of the water inlet pipe 6 is communicated with the grinding tank 1, the spray head is arranged in the collecting bucket 2 and is communicated with the grinding tank 1, the water inlet pipe 5 is communicated with the lower part of the collecting bucket 2, an inclined tee joint 7 is communicated between the water outlet pipe 4 and the water inlet pipe 6, the inclined tee joint 7 is also communicated with a water return pipe 8, the water outlet pipe 4 is obliquely communicated with the lower section of the water inlet pipe 6, the upper section of the water return pipe 8 is vertically communicated with the lower section of the water inlet pipe 6, and the bottom end of the water return pipe 8 is communicated with the collecting bucket 2, and is used for enabling steel sand and water in the water inlet pipe 6 to flow back into the collecting bucket 2 under the action of gravity when the conveying pump 3 is stopped. Through the intercommunication setting of tee bend 7, when delivery pump 3 is shut down, the steel sand in the section that upper hose 6 is close to delivery pump 3 and vertical setting can fall back downwards under the effect of gravity, through the vertical intercommunication setting of upper hose 6 and wet return 8, the steel sand that falls back in the upper hose 6 can keep the trend of flowing down to flow into in the wet return 8, and flow back to collecting hopper 2 along wet return 8, thereby prevent that the steel sand from getting into in the delivery pump 3, avoid leading to the jam of delivery pump 3, thereby realize low water yield, the stable high-efficient of steel sand.
In this embodiment, the included angle a between the water outlet pipe 4 and the water inlet pipe 6 is an obtuse angle. When the axis of the water feeding pipe 6 and the axis of the water return pipe 8 are positioned on the same line, the water outlet pipe 4 is obliquely arranged and communicated with the water feeding pipe 6, and an included angle a formed by the water outlet pipe 4 and the water return pipe 8 is an acute angle.
In this embodiment, the water outlet pipe 4 is provided with a water outlet valve 41, and the water inlet pipe 5 is provided with a water inlet valve. The outlet valve 41 and inlet valve are opened before the transfer pump 3 is started and closed after the transfer pump 3 is stopped.
In this embodiment, the water return pipe 8 is provided with a water return valve 81. The return valve 81 is closed before the feed pump 3 is turned on and is opened before the feed pump 3 is stopped.
In this embodiment, the water inlet pipe 5 is connected to a water replenishing pipe 9, and the water replenishing pipe 9 is connected to the upper part of the collecting bucket 2 and is used for sucking water. The water at the upper part of the collecting hopper 2 can be conveyed to one end of the water inlet pipe 5, which is close to the conveying pump 3, through the water supplementing pipe 9.
