Abstract
The utility model discloses a backwater water prevention and sand feeding device of a water cutting machine. The device comprises a sand blasting nozzle; the upper part of the sand blasting nozzle is communicated with an upright water jet flow passage; the lateral part of the water jet flow passage is communicated with a shakeout passage; the other end of the shakeout passage is communicated with a mixing chamber; the upper part of the mixing chamber is communicated with a sand inlet pipe; and a vent hole communicated atmosphere is formed at the lateral part of the mixing chamber. The utility model adopting the technical scheme has the advantages that when a water valve of the machine is turned off temporarily, redundant backwater or sand can flow out from the vent hole, and the phenomenon of high-level backwater is avoided, so that sand entering in the sand inlet pipe can keep dry, and neither can absorb water, nor can block the sand inlet pipe, and the processing continuity and trimming quality are further guaranteed.
Description
Technical field
The utility model relates to the anti-backwater of a kind of water cutting machine and advances the sand device.
Background technology
It is 02134867.7 backwater control system of water cut-off machine patent of invention that on April 30th, 2003 China discloses application number, it comprises along the (operating) water nozzle of water (flow) direction series connection and sand blasting mouth, hybrid chamber between (operating) water nozzle and sand blasting mouth has sand inlet, sand inlet is connected with the sediment transport pipe, the (operating) water nozzle water inlet is connected with a high-pressure water generation systems, particularly its be provided with one with (operating) water nozzle and sand blasting mouth between the bypass channel that is communicated with of hybrid chamber, this bypass channel is connected to the gas outlet of a Pneumatic valve open in usual, and the air inlet of Pneumatic valve open in usual is communicated with atmosphere.It is discharged the water that flows backwards by bypass channel, avoids current to flow backwards from sand inlet and enters the sediment transport pipe.Though it has also played the purpose that prevents backwater to a certain extent, its complex structure, anti-backwater effect is good inadequately.
The utility model content
Technical problem to be solved in the utility model just provides a kind of simple in structure, and the effective anti-backwater of water cutting machine of anti-backwater advances the sand device.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of anti-backwater of water cutting machine advances the sand device, comprise blast nozzle, described blast nozzle top is communicated with a vertical water-jet runner, it is characterized in that: described water-jet runner sidepiece is communicated with a knockout road, the described knockout road other end is communicated with a mixing chamber, and the mixing chamber top is communicated with a sand-feeding tube, and described mixing chamber sidepiece is established a passage and is communicated with atmosphere.
As preferably, described passage is located at upside in the mixing chamber.
As preferably, described passage diameter is greater than the sand-feeding tube diameter.Prevent backwater.
As preferably, described mixing chamber is a transparent configuration.Be convenient to observe the mixing indoor conditions.
As preferably, described sand-feeding tube is soft pipe.
As preferably, described knockout road and horizontal direction inclination 30-60 degree enter the water-jet runner.The knockout spontaneous current is gone into the water jet road.
The utility model is realized good anti-backwater effect owing to adopted technique scheme by simple structure.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, advance the embodiment of sand device for the anti-backwater of a kind of water cutting machine of the utility model, comprise blast nozzle 1, described blast nozzle top is communicated with a vertical water-jet runner 2, described water-jet runner sidepiece is communicated with a knockout road 3, the described knockout road other end is communicated with a mixing chamber 4, and the mixing chamber top is communicated with a sand-feeding tube 6, and described mixing chamber sidepiece is established a passage 5 and is communicated with atmosphere.Described passage 5 is located at upside in the mixing chamber.Described passage diameter is greater than sand-feeding tube 6 diameters.Described mixing chamber 4 is a transparent configuration.Described sand-feeding tube 6 is soft pipe.Described knockout road 3 enters water-jet runner 2 with horizontal direction inclination 30-60 degree.
Mixing chamber Lower Half sand and water fully are mixed into muddy, and like this, when machine works, water jet causes instantaneous vacuum, and passage fully enters air so, and atmospheric pressure advances sand and water and be blended in the water jet.When machine Temporarily Closed water valve, unnecessary backwater or sand are arranged, can flow out from passage, can high-order backwater.Like this, the sand that advances in the sand flexible pipe can not absorb water, and keeps dry, and can not cause the into obstruction of sand flexible pipe yet, thereby has guaranteed the continuity and the trimming quality of processing.
