Detailed description of the invention
As shown in Figure 1-2, a kind of MZ type buries scraper plate mud conveyer, including afterbody 15, lower horizontal segment 1, lower bending section 2, vertical section 3, upper bending section 4, upper horizontal segment 5 and head 16, the housing 6 of described lower horizontal segment 1, vertical section 3 and upper horizontal segment 5 is convex structure, flight chain is arranged in housing 6, and the duplex chain 7 of flight chain is arranged on the sleeveless jacket 8 of housing 6, in the scraper plate 9 of flight chain is arranged on the groove 10 of housing 6 and groove 10 holding interval.Wherein duplex chain and the scraper plate of flight chain all uses 304 rustless steels, and carries out Nitrizing Treatment, so for the mud that corrosivity is extremely strong, can extend the service life of flight chain.Owing to semi-dry sludge is a kind of relatively thickness and the higher material of sand factor, the duplex chain of the flight chain in this device is positioned on the sleeveless jacket 8 of housing 6, and scraper plate is in export-oriented layout with great wheel 28, for common MZ type embedded scraper transporter, on the one hand the heavy wear that the friction of the contact surface in a big way between chain and mud causes can be avoided, on the other hand can be prevented effectively from mud to be bonded on flight chain and cause unloading difficulties, get stuck and the problem such as abrasion, also can reduce the skew of sprocket wheel simultaneously.
As it is shown on figure 3, be the most at least provided with a guiding mechanism 11 at described lower bending section 2, upper bending section 4, guiding mechanism 11 includes paired directive wheel 12, and directive wheel 12 engages with duplex chain 7 and passes through the axis of guide 13 and installs on pedestal 14.Under common MZ type embedded scraper transporter, bending section middle scraper chain is dependent on central dividing plate directional support and carries out the horizontal segment transition with vertical section, but semi-dry sludge water content is between 30%-40%, granularity is between 1mm-3mm, sand factor > 24%, owing to sand factor is higher induction system inherently had serious abrasion, add the phase mutual friction in running, individual month of about 2-3 after common MZ type embedded scraper transporter is installed, principal contact surfaces is just worn through, mud is caused to overflow, not only have impact on the operation of material conveying, increase the cleaning of overflow, cause serious environmental pollution simultaneously.Duplex chain guiding from horizontal segment to vertical section is carried out by directive wheel, for original chain slides along central dividing plate, sliding friction is converted into rolling friction, reduce the abrasion of duplex chain, extend the service life of equipment, for closed conveying equipment, maintenance can be reduced and change number of times, and then improve production efficiency.
As shown in Figure 4, at described upper bending section 4, two guiding mechanisms 11 are installed, respectively close to vertical section 3 upper end, upper horizontal segment 5 left end.A guide wheel installed in the middle of upper bending section 4 by common MZ type embedded scraper transporter, when material is risen to upper end horizontal segment by down, intermediate trailing wheel needs to bear mud and whole peripheral forces of material strip and radial force, transporting resistance is caused to strengthen, run overload, in addition to causing electricity usage and increasing, also make the serious wear of intermediate trailing wheel and dividing plate.The application uses two guiding mechanisms, when flight chain enters upper bending section 4, the directive wheel 12 of upper and lower side rotates with chain, not only reduce the load that single directive wheel bears, reduce guide wheel and the abrasion of dividing plate, the laminating number of chain and directive wheel can be increased simultaneously, reduce the resistance that chain is subject to, reduce the bending stress that chain intermediate plate is subject to, improve the working environment of chain.
As it is shown in figure 5, described scraper plate 9 is removably mounted on duplex chain 7 by the connecting plate 17 inside duplex chain 7.Thus structure, owing to the major impetus of mud conveying comes from the thrust of scraper plate, and mud is the material that a kind of sand factor is higher, even if using high-abrasive material, also can produce abrasion, it is therefore desirable to detachably install and ensure installation strength, and being convenient for changing.
