Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the stirring device comprises a cover body 1, a motor 2, a stirring shaft 3, a main stirring blade 4, a scraping plate 5, a transverse straight part 6, a vertical part 7, a limiting strip 8, a stirring barrel 9, a clamping part 10, a communicating part 11 and an auxiliary stirring blade 12.
Example one
As shown in fig. 1, the stirring device for asphalt waterproof materials comprises a stirring barrel 9, wherein a cover body 1 is arranged at the top of the stirring barrel 9, a feeding port (not shown in the figure) is formed in the cover body 1, and a sealing plate is hinged to the feeding port. The vertical (mixing) shaft 3 that is provided with in 1 bottom of lid, (mixing) shaft 3 rotates with the apron to be connected, installs motor 2 on the apron, motor 2's output shaft and (mixing) shaft 3 fixed connection.
A plurality of main stirring blades 4 are transversely welded on the stirring shaft 3, the main stirring blades 4 in the embodiment are longitudinally welded on the stirring shaft 3 in a group, and the number of the main stirring blades 4 in each group is five. 4 free ends of every group main mixing blade can dismantle and be provided with stair-like scraper blade 5 (scraper blade 5 includes two vertical portions 7, and horizontal fixedly connected with a plurality of horizontal poles between two vertical portions 7), and scraper blade 5 is wear-resisting and heat-resisting scraper blade 5, can adopt materials such as pottery, silica gel to make. Specifically, the mounting groove that is used for installing scraper blade 5 is all offered to 4 free ends of every group main mixing blade, and the mounting groove is vertical to run through main mixing blade 4. As can be seen from fig. 2, the mounting groove includes an inner clamping portion 10 and an outer communicating portion 11, the communicating portion 11 communicates with the clamping portion 10, and the outer side of the communicating portion 11 transversely penetrates through the main stirring vane 4. The clamping part 10 is used for clamping the vertical part 7 of the scraper 5, the communication part 11 is used for accommodating the transverse and straight part 6 of the scraper 5, specifically, the clamping part 10 is circular, the cross section of the vertical part 7 of the scraper 5 is also circular, the width of the communication part 11 is smaller than the diameter of the clamping part 10, the diameter of the clamping part 10 is equal to or slightly larger than the diameter of the vertical part 7 of the scraper 5, and the vertical part of the scraper 5 is vertically inserted into the clamping part. Since the width of the communication portion 11 is smaller than the diameter of the chucking portion 10, the vertical portion 7 of the squeegee 5 can be chucked in the chucking portion 10.
A supporting plate is welded at the bottom of the mounting groove on the main stirring blade 4 (the lowest main stirring blade 4) at the bottom of the stirring shaft 3, and a plurality of material leaking holes are formed in the supporting plate. All vertical welding has a plurality of spacing 8 between five main stirring vane 4 of every group, has two spacing 8 at least between two main stirring vane 4 in this embodiment, and when spacing 8 was two, these two spacing 8 best use the centre of a circle of chucking part 10 as the symmetry line symmetry setting. The installation of the screed 5 is achieved by inserting the vertical portion 7 of the screed 5 vertically into the mounting groove, i.e. as shown in fig. 1. The top of the scraper 5 is welded with a pull ring (not shown in the figure), and the scraper 5 is conveniently pulled out by the pull ring, so that the replacement of the scraper 5 is realized.
The specific implementation process is as follows:
the closing plate is opened, other raw materials such as asphalt, a modifier and the like are filled into the stirring barrel 9 from the feeding port, then the feeding port is sealed by the closing plate, and the starting motor 2 drives the stirring shaft 3 to rotate. Stirring shaft 3 drives main stirring vane 4 and rotates, and main stirring vane 4 stirs the pitch in agitator 9, and in the time of the stirring, scraper blade 5 can scrape the pitch on the inner wall of agitator 9 down to avoid pitch adhesion on the inner wall of agitator 9.
In the embodiment, the wear-resistant and heat-resistant scraper 5 is adopted, so that the service life of the scraper 5 can be prolonged, and the wear speed of the scraper 5 can be reduced. In addition, the embodiment adopts the stair-shaped scraper 5, and after one vertical part 7 of the scraper 5 is worn, the scraper 5 can be detached, so that the worn vertical part 7 is connected with the main stirring blade 4, and the other vertical part 7 is replaced to scrape the asphalt on the inner wall of the stirring barrel 9. The whole scraper 5 does not need to be replaced, and the cost is saved. Furthermore, the installation of scraper blade 5 can be realized in the vertical clamping part 10 that inserts the vertical portion 7 of scraper blade 5 in the mounting groove only to adopt the mounting groove connecting scraper blade 5 that has clamping part 10 and intercommunication portion 11, easy dismounting. Set up chucking portion 10 and intercommunication portion 11, can be at main stirring vane 4's the axial chucking scraper blade 5, avoid scraping blade 5 to receive centrifugal action and main stirring vane 4 to break away from in the stirring process.
The mounting groove bottom on the main stirring vane 4 of lower floor is provided with the backup pad, can support scraper blade 5 on vertical, avoids scraper blade 5 to receive the action of gravity to move down at the stirring in-process, breaks away from with main stirring vane 4 even, has improved scraper blade 5's installation stability. Set up the hole that leaks in the backup pad, can avoid pitch to long-pending stay in the mounting groove. The vertical spacing strip 8 that is provided with between the main stirring vane 4 of every group can give scraper blade 5 spacing when inserting scraper blade 5, takes place crooked influence installation when avoiding scraper blade 5 to insert.
Example two
As shown in fig. 3, the present embodiment is different from the first embodiment in that an auxiliary stirring blade 12 is provided on the main stirring blade 4 at the bottom of the stirring shaft 3. During the stirring, supplementary stirring vane 12 can follow main stirring vane 4 and rotate to stir pitch in the bottom of agitator 9, can avoid pitch to sink the end.
EXAMPLE III
The difference between this embodiment and the first embodiment is that the side wall of the mixing tank 9 is communicated with an exhaust pipe (not shown in the figure), an exhaust fan is installed in the exhaust pipe, and a filter layer is also installed in the exhaust pipe, in this embodiment, the filter layer is an activated carbon layer, and the activated carbon can be packaged in a mesh or other air-leaking container, and then is directly placed or is detachably installed in the exhaust pipe by using bolts and the like. Set up blast pipe and air discharge fan and can be with the waste gas discharge that pitch produced in the agitator 9, waste gas discharges after filtering and can avoid its polluted environment and air.
