Abstract
The utility model discloses a rotary scraper clearing block device which comprises a plate inserting door and a coal falling pipe. The rotary scraper clearing block device further comprises a control box, a flange plate and a driving motor. The coal falling pipe comprises an upper coal falling pipe and a lower coal falling pipe. The plate inserting door is arranged on the upper coal falling pipe. The flange plate is arranged between the upper coal falling and the lower coal falling pipe. The control box controls the driving motor to start and stop and the plate inserting door to open and close. The driving motor drives the flange plate to rotate. A scraper is installed on the flange plate. According to the rotary scraper clearing block device, the phenomenon that coal is blocked inside the coal falling pipe in a coal furnace of a power plant does not appear any longer, and generating efficiency is improved greatly.
Description
Technical field
The utility model relates to a kind of block clearing apparatus, particularly a kind of revolving scraper blockage-clearing device for power plant's coal stove coal spout block clearing.
Background technology
In the prior art, what the generating of most of power plant was still adopted is to generate electricity by burning of coal, the coal that power plant is used for generating electricity has impure mud coal and contains the wet coal of certain moisture, yet when coal in combustion bin, coal in the coal spout of combustion bin top is easy to stop up in dropping process, coal partly carries out blocking cleaning work in case stop up the coal supply that just must close insertion plate door partition coal spout and its top, yet must stop material loading when now the obstruction coal in the coal spout being carried out block clearing, then manually carrying out block clearing then must stop coaling machine and carry out material loading, stopping material loading then can affecting the generating efficiency of power plant, and then so that production capacity has been subject to great restriction.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of revolving scraper blockage-clearing device that prevents chute blockage in the coal spout.
The technical solution of the utility model is achieved in that
A kind of revolving scraper blockage-clearing device, comprise insertion plate door and coal spout, also comprise control cabinet, ring flange and drive motors, described coal spout comprises coal spout and dropping coal tube, described insertion plate door is arranged on the described upper coal spout, and described ring flange is arranged between described upper coal spout and the dropping coal tube, the start and stop of described control cabinet control drive motors and the switch of insertion plate door, described drive motors drives described ring flange and rotates, and at described ring flange scraper is installed.
Above-mentioned revolving scraper blockage-clearing device has gap on the described insertion plate door, and described gap has and the corresponding shape of described scraper cross section.
Above-mentioned revolving scraper blockage-clearing device also comprises main drive wheel, and described main drive wheel links together by shaft coupling and drive motors output shaft, and described main drive wheel drives described ring flange and rotates.
The beneficial effects of the utility model are: the chute blockage phenomenon so that no longer occur in power plant's coal stove coal spout, so that generating efficiency is greatly improved in revolving scraper blockage-clearing device energy.
Description of drawings
Fig. 1 is the forward sight structural representation of the utility model revolving scraper blockage-clearing device,
Fig. 2 is the plan structure schematic diagram of the utility model revolving scraper blockage-clearing device,
Fig. 3 is the structural representation of the insertion plate door of the utility model revolving scraper blockage-clearing device when being in closed condition.
Among the figure: 1-coal spout, 2-scraper, 3-ring flange, 4-drive motors, 5-main drive wheel, 6-insertion plate door, 7-control cabinet.
The specific embodiment
By reference to the accompanying drawings the utility model is described further:
As depicted in figs. 1 and 2, a kind of revolving scraper 2 blockage-clearing devices, comprise insertion plate door 6 and coal spout 1, also comprise control cabinet 7, ring flange 3 and drive motors 4, described coal spout 1 comprises coal spout 1 and dropping coal tube 1, described insertion plate door 6 is arranged on the described upper coal spout 1, described ring flange 3 is arranged between described upper coal spout 1 and the dropping coal tube 1, the start and stop of described control cabinet 7 control drive motors 4 and the switch of insertion plate door 6, described drive motors 4 drives described ring flange 3 and rotates, and at described ring flange 3 scraper 2 is installed.
As shown in Figure 3, have gap on the described insertion plate door 6, described gap has and the corresponding shape of described scraper 2 cross sections.
Also comprise main drive wheel 5, described main drive wheel 5 links together by shaft coupling and drive motors 4 output shafts, and described main drive wheel 5 drives described ring flange 3 by belt or hinge and rotates.
The revolving scraper 2 blockage-clearing device courses of work:
As shown in Figure 2, open by control cabinet 7 control insertion plate doors 6, opening insertion plate door 6 rear drive motors 4 starts, drive motors 4 drives main drive wheel 5 and rotates, ring flange 3 is installed on the gear, main drive wheel 5 drives the gear rotation that ring flange 3 is installed by the mode of gear engagement, ring flange 3 rotates and then drives scraper 2 and rotates, scraper 2 rotates the mud coal or the wet coal that stick on coal spout 1 wall are come off, mud coal in the middle of the coal spout 1 or wet coal be not because there is impetus, so can not stop up the situation of coal spout 1; When waiting not need to generate electricity, control cabinet 7 control drive motors 4 rotate a period of times so that scraper 2 stops the rotation after resting on initial position, then control cabinet 7 control insertion plate doors 6 are closed, the cross section of the gap on the insertion plate door 6 and scraper 2 has corresponding shape, so when insertion plate door 6 was closed, insertion plate door 6 cooperated scraper 2 can seal coal spout 1.
7 pairs of drive motors 4 of control cabinet and insertion plate door 6 adopt the mode of electric controlled interlocking to control, and namely when insertion plate door 6 was in closed condition, drive motors 4 can't start; And when drive motors 4 was in rotation status, insertion plate door 6 can't be closed.
Above-described embodiment only is for illustrating that clearly the utility model creates example, and is not the restriction of the utility model being created the specific embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.All any apparent variation or changes being extended out within spirit of the present utility model and the principle still are among the protection domain of the utility model creation claim.
