[0017] By adopting the above technical solution, when installing the filter mesh bag, the bag mouth is sleeved on two arc-shaped pressing plates, and then the pull rod is pulled to drive one arc-shaped pressing plate to move, and finally the arc-shaped pressing plate presses the filter mesh bag against the inner wall of the collecting pipe. Then, the sliding insertion rod is used to insert the insertion rod into the insertion hole, and the limiting part is used to restrict the movement of the insertion rod. At this time, the pressing of one arc-shaped pressing plate is completed, and the other arc-shaped pressing plate is also operated in the same way.

Detailed implementation manners
[0029] The following combines the appended Figure 1 and the appended Figure 2 to further elaborate on the present application, so that the technical solution of the present application is easier to understand and master.
[0030] A stirring and mixing device for raw materials of ultra-high performance concrete premix in this embodiment includes a tank body 1, a stirring rod 2 rotatably connected inside the tank body 1, and a first motor 3 fixed on the tank body 1 for driving the stirring rod 2 to rotate. A feeding port 11 is opened at the top of the tank body 1, a discharging port 12 is opened at the bottom of the tank body 1, and an electric control valve 13 is installed in the discharging port 12.
[0031] A dust exhaust port 14 is opened on the side wall of the tank body 1, and a second flange 17 is provided on the dust exhaust port 14. A collecting pipe 4 is further provided outside the tank body 1. A first flange 41 is provided at the end of the collecting pipe 4, and the first flange 41 is connected to the second flange 17 by a bolt 73.
[0032] Two arc-shaped pressing plates 45 are slidably connected in the collecting pipe 4 along a direction perpendicular to the axis of the collecting pipe 4. The two arc-shaped pressing plates 45 are symmetrically distributed in the collecting pipe 4, and the two arc-shaped pressing plates 45 are used to extend into the bag mouth of the filter mesh bag 9 and press the bag mouth of the filter mesh bag 9 against the inner wall of the collecting pipe 4.
[0033] Two control assemblies 6 are further provided on the collecting pipe 4 for respectively controlling the sliding of the two arc-shaped pressing plates 45. The control assembly 6 includes a pull rod 61 provided on the arc-shaped pressing plate 45 and a plug rod 62 slidably connected to the outer wall of the collecting pipe 4 along the axis of the collecting pipe 4. The axis of the pull rod 61 is perpendicular to and intersects with the axis of the collecting pipe 4. One end of the pull rod 61 away from the arc-shaped pressing plate 45 extends out of the collecting pipe 4, and a jack 611 for plugging and matching with the plug rod 62 is provided at the end of the pull rod 61 extending out of the collecting pipe 4. When the plug rod 62 is inserted into the jack 611, the arc-shaped pressing plate 45 abuts against the inner wall of the collecting pipe 4.
[0034] The collection component further includes a limiting portion 7 for restricting the sliding of the insertion rod 62. The limiting portion 7 includes a first threaded hole 71 formed in the insertion rod 62, a second threaded hole 72 formed in the collection pipe 4, and bolts 73 respectively threadedly connected in the first threaded hole 71 and the second threaded hole 72.
[0035] A filter mesh bag 9 is provided in the collection pipe 4. Hook surface magic tapes 81 and loop surface magic tapes 82 are provided on the inner wall of the bag mouth of the filter mesh bag 9, and the hook surface magic tapes 81 and the loop surface magic tapes 82 are connected end to end with each other. In the initial state, the two arc-shaped pressing plates 45 respectively press the hook surface magic tape 81 and the loop surface magic tape 82, and press the bag mouth of the filter mesh bag 9 against the inner wall of the collection pipe 4. At the same time, the two insertion rods 62 are inserted into the two insertion holes 611, and the two second bolts 73 are respectively threadedly connected in the corresponding first threaded hole 71 and the second threaded hole 72.
[0036] When installing the filter mesh bag 9, put the bag mouth on the two arc-shaped pressing plates 45, then pull one of the pull rods 61 to drive one of the arc-shaped pressing plates 45 to move. Finally, make the arc-shaped pressing plate 45 press the filter mesh bag 9 against the inner wall of the collection pipe 4. At this time, the insertion hole 611 on the pulled pull rod 61 will be aligned with the insertion rod 62 and located on the movement path of the insertion rod 62. Then slide the insertion rod 62 to insert the insertion rod 62 into the insertion hole 611. After the insertion rod 62 is inserted into the insertion hole 611, align the first threaded hole 71 with the second threaded hole 72, and then threadedly connect the bolt 73 in the first threaded hole 71 and the second threaded hole 72, so as to complete the restriction of one insertion rod 62. Do the same for the other arc-shaped pressing plate 45, and finally make the two arc-shaped pressing plates 45 press the filter mesh bag 9 against the inner wall of the collection pipe 4. In this way, the installation of the filter mesh is completed.
[0037] When disassembling the filter mesh, screw out the two bolts 73 from the two first threaded holes 71 and the two second threaded holes 72, then move the two insertion rods 62 to pull the two insertion rods 62 out of the two insertion holes 611, and then push the two pull rods 61 to make the two arc-shaped pressing plates 45 move closer to each other. In this way, the pressing of the two arc-shaped pressing plates 45 on the filter mesh bag 9 can be released, so that the filter mesh belt can be taken out of the collection pipe 4. It should be noted here that before taking out the filter mesh bag 9 from the collection pipe 4, make the hook surface magic tape 81 and the loop surface magic tape 82 stick to each other to seal the bag mouth of the filter mesh bag 9, preventing dust from leaking from the filter mesh bag 9 when taking it.
[0038] A rotating rod 42 is rotatably connected inside the collecting pipe 4. The rotating rod 42 is located between the filter bag 9 and the first flange 41. The axis of the rotating rod 42 is perpendicular to and coincides with the axis of the collecting pipe 4. A sealing disk 43 for sealing the inner cavity of the collecting pipe 4 is provided on the rotating rod 42. One end of the rotating rod 42 extends out of the collecting pipe 4 and is connected with a handle 44. Before disassembling the collecting pipe 4, the rotating rod 42 is rotated through the handle 44 to make the sealing disk 43 seal the collecting pipe 4, preventing the dust in the filter bag 9 from leaking into the surrounding environment during the disassembly of the collecting pipe 4 and the filter bag 9.
[0039] A rotating shaft 15 is also rotatably connected to the top inside the tank body 1. The axis of the rotating shaft 15 coincides with the axis of the collecting pipe 4. A plurality of fan blades 16 are fixed on the rotating shaft 15. A driving part 5 is also provided inside the tank body 1. The driving part 5 is used to drive the rotating shaft 15 to rotate so that the plurality of fan blades 16 blow the dust into the dust discharge port 14. The driving part 5 includes a first bevel gear 51 provided on the rotating shaft 15 and a second bevel gear 52 provided on the stirring rod 2. The first bevel gear 51 meshes with the second bevel gear 52.
[0040] After the raw materials are put into the tank body 1 through the feeding port, the first motor 3 starts to drive the stirring rod 2 to rotate and stir the mixed raw materials. At this time, a lot of dust will be generated inside the tank body 1. When the stirring rod 2 rotates, it will drive the second bevel gear 52 to rotate. When the second bevel gear rotates, it will drive the rotating shaft 15 to rotate through the first bevel gear 51, so that the plurality of fan blades 16 rotate. After the plurality of fan blades 16 rotate, they will blow the dust into the filter bag 9 through the dust discharge port 14 and the collecting pipe 4. Then the filter bag 9 will collect and filter the dust, preventing the dust from overflowing the tank body 1 and polluting the environment.
[0041] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by this application.
