Detailed description of the invention
The invention provides a kind of dredger for solid material, for making object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of dredger for solid material, as shown in Figure 1 with shown in Fig. 2, it comprises for providing the water tank 1 of hydraulic pressure, hydraulic actuating cylinder 2 cuts somebody's hair 3 with block clearing, described water tank 1 is connected with described hydraulic actuating cylinder 2 by the first water route 5, water route 4, second, piston rod 6 and the described block clearing of described hydraulic actuating cylinder 2 are cut somebody's hair and 3 to be connected, described first water route 4 is connected with described hydraulic actuating cylinder 2 upper end, and described second water route 5 is connected with 2 ends under described hydraulic actuating cylinder.
Further, described first water route 4 is provided with high-pressure hydraulic pump 7, first automatic valve 8 and boiler check valve 9 from described water tank 1 to described hydraulic actuating cylinder 2 direction; Described first water route 4 between described high-pressure hydraulic pump 7 and described first automatic valve 8 is provided with overflow water route 10, and described overflow water route 10 is connected with described water tank 1, and described overflow water route 10 is provided with by pass valve 11.Described second water route 5 is provided with the second automatic valve 12.
In the preferred embodiment, as shown in Figures 1 and 2, described hydraulic actuating cylinder 2 comprises cylinder body 13, and be provided with piston 14 in described cylinder body 13 one end, the other end is provided with orienting sleeve 15, and described piston 14 has gap with the contact surface of described cylinder body 13; Be provided with a spring 16 between described piston 14 and described orienting sleeve 15, described piston 14 is connected with one end of described piston rod 6, and described piston rod 6 other end is cut somebody's hair through described spring 16, described orienting sleeve 15 and described block clearing and 3 to be connected.
Further, described piston 14 forms a hydraulic pressure chamber with described cylinder body 13 corresponding end, and described first water route 4 is connected with described hydraulic pressure chamber; Described orienting sleeve 15 is provided with liquid outlet 17 with described cylinder body 13 junction, and described liquid outlet 17 is connected with described second water route 5.And be dynamic seal between described piston rod and described orienting sleeve.
In order to further describe the present invention, as shown in Figure 3, in concrete dredging process, when dredger works, Automated condtrol is opened described first automatic valve 8, is opened described second automatic valve 12 and described high-pressure hydraulic pump 7, from described water tank 1, water is transported in described hydraulic actuating cylinder 2, major part water promotes described piston 14 and moves, thus drive described piston rod 6 and described block clearing to cut somebody's hair 3 motions, the described block clearing 3 promotion solids bed of materials of cutting somebody's hair move downward, and have a small amount of water to play lubricating effect under described cylinder body 13 and the slit flow of described piston 14 simultaneously.
When described block clearing cut somebody's hair 3 shift nadir onto time, described hydraulic actuating cylinder 2 pressure increase, after after some seconds, pressure reaches the operation pressure of described by pass valve 11 setting, described by pass valve 11 works, close described first automatic valve 8, open described by pass valve 11 and form self-loopa, water in described hydraulic actuating cylinder 2 under seepage flows in described water tank 1 by described second automatic valve 12, now in described hydraulic actuating cylinder 2 described spring 16 screen resilience effect under, described piston rod 6 drives described block clearing to cut somebody's hair 3 upward movements, after some seconds of setting, described first automatic valve 8 repeats opening action, make described piston rod 6 drive described block clearing to cut somebody's hair 3 to move downward, formed upwards with downward crank motion.
Allow the trickling of solid material form following current in reciprocating push-and-pull process be unlikely to again to take arch.Ensure that in drawing process described block clearing cut somebody's hair 3 bottoms the solids bed of material not by top express material formed take arch, when again promoting, described block clearing 3 bottoms of cutting somebody's hair form an opposing cavities and are beneficial to top material and drop down fast, go round and begin again, avoid and occur that material forms the situation of taking arch.When using this system at high temperature under high pressure, described first automatic valve 8 can select resistant to elevated temperatures high pressure valve with described second automatic valve 12.Described in during High Temperature High Pressure, the first automatic valve 8 and described second automatic valve 12 are closed condition, and the pipeline now after described hydraulic actuating cylinder 2 and described first automatic valve 8, described second automatic valve 12 forms equipressure in container, can not form distortion.And under atmospheric pressure state after High Temperature High Pressure during blowing, ensure that described hydraulic actuating cylinder 2 can normal crank motion push-and-pull material, material is discharged smoothly in tank.
And rubber one series products can not be adopted, because can lose efficacy in the case of a high temperature for described cylinder body 13 with the seal ring of described piston 14.Sealing between described cylinder body 13 and described piston rod 6 can not adopt conventional seal form, so also can lose efficacy in the case of a high temperature.Between above 2 points, the transmission of power should be ensured, ensure that described cylinder body 13 and described piston 14 be not by locking under high-pressure situations again, so adopt the material of the overall high temperature resistant cast iron of little deformation to make described piston 14.And in liquid-driving process, there is a small amount of water to serve liquid film lubrication effect under the slit flow between described cylinder body 13 and described piston 14, protect described cylinder body 13 and described piston 14.Hard between described cylinder body 13 and described piston rod 6 seals the frame mode adopting described orienting sleeve 15, serve the effect of fluid-tight platform, to have stayed the water flowed down to be blocked in along the gap between described cylinder body 13 and described piston 14 described orienting sleeve 15 and described cylinder body 13, be discharged in described water tank 1 by described liquid outlet 17, contaminated material in material can not be flow into along described piston rod 6.Gap between the described piston rod 6 selected in high-pressure process and described orienting sleeve 15 can not be taken dust in described cylinder body 13 under pressure, and described cylinder body 13 end cap also has scraper effect that the dust be attached on outside described piston rod 6 is wiped off.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
