Description

Technical Field

[0001] The utility model relates to a spiral ribbon mixer for continuous production of mud stirring, mixing and conveying. Background Art

[0002] When spiral mixers are used for mixing silt solidified soil, in order to ensure the mixing effect, the mixing barrel is made very long, so as to increase the mixing time and ensure the uniformity of mixing. The problem caused by the long structure is that a large construction site is required, and the transportation cost is also high after the equipment is produced. Summary of the invention

[0003] The utility model provides a ribbon mixer for continuous production of mud stirring, mixing and conveying in order to solve the problems existing in the prior art.

[0004] The technical solutions adopted in this utility model are:

[0005] A spiral ribbon mixer for continuous production of mud stirring, mixing and conveying, comprising a stirring shaft, a spiral ribbon, a crushing tool, a stirring barrel, a baffle and a motor. The stirring shaft is horizontally rotatably connected to the stirring barrel, and the motor drives the stirring shaft to rotate. Two spiral ribbons are provided and arranged at intervals and fixed on the stirring shaft in the same spiral direction. The baffle is placed between the two spiral ribbons, the baffle is fixedly connected to the inner wall of the stirring barrel, and the bottom surface of the baffle is placed above the stirring shaft. A plurality of crushing tools are fixed on the stirring shaft at intervals.

[0006] Furthermore, the baffle is a rectangular plate, a semicircular arc groove is provided on the bottom surface of the baffle, and the stirring shaft is passed through the bottom of the semicircular arc groove.

[0007] Furthermore, the crushing tool is a detachable structure, comprising a mounting block and a blade, the mounting block is fixed on the stirring shaft, and the blade is fixedly connected to the mounting block.

[0008] Furthermore, the mounting block includes two blocks with semicircular grooves. After the two blocks are fixed by bolts, the two semicircular grooves are combined to form a circular hole for passing the stirring shaft. The blade is fixed between the two blocks, and a key groove is provided on the inner arc surface of one of the blocks.

[0009] Furthermore, the mixing barrel is a closed mixing barrel, and a feed inlet and a discharge outlet are provided on the mixing barrel.

[0010] Furthermore, a drain port is provided at the bottom of the mixing barrel.

[0011] Furthermore, the baffle is arranged in the middle of the mixing barrel.

[0012] The utility model has the following beneficial effects:

[0013] 1) The utility model adds a baffle in the mixing barrel. Due to the existence of the baffle, the curing agent and the sludge can be blocked from running toward the discharge port, thereby lengthening the residence time of the curing agent and the sludge mixture, ensuring better and more sufficient stirring, and improving the uniformity of stirring without increasing the length of the spiral belt. The utility model occupies a relatively small area and has a compact structure.

[0014] 2) The utility model provides a plurality of crushing cutters arranged at intervals on the stirring shaft. The arrangement of the crushing cutters can facilitate the crushing of block sludge and ensure the stirring and mixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 It is a left side sectional view of the utility model.

[0017] Figure 3 This is the structural diagram of the crushing tool. Implementation

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1 and Figure 2 The utility model is a continuous production ribbon mixer for mud mixing, mixing and conveying, comprising a mixing shaft 1, a spiral belt 2, a crushing tool 3, a mixing barrel 4, a baffle 5 and a motor 6. The mixing barrel 4 and the motor 6 are fixed on a frame. The mixing barrel 4 is a closed mixing barrel, and a feed port and a discharge port are provided on the mixing barrel. The mixing shaft 1 is horizontally rotatably connected to the mixing barrel 4 through a bearing, and the motor 6 drives the mixing shaft 1 to rotate through a belt linkage. Two spiral belts 2 are provided and arranged at intervals, and are fixed on the mixing shaft 1 in the same spiral direction. The baffle 5 is placed between the two spiral belts 2, and the baffle 5 is fixedly connected to the inner wall of the mixing barrel 4, and the bottom surface of the baffle 5 is placed above the mixing shaft 1, and a plurality of crushing tools 3 are fixed on the mixing shaft 1 at intervals.

[0020] The utility model provides a baffle in the stirring barrel, and the baffle is located above the stirring shaft. When in use, the curing agent and the sludge enter the barrel from the feeding port of the stirring barrel together. In the process of the spiral belt 2 carrying the curing agent and the sludge toward the discharging port of the stirring barrel, the curing agent and the sludge are stirred and mixed. Due to the existence of the baffle, the curing agent and the sludge can be prevented from running toward the discharging port, thereby lengthening the residence time of the curing agent and the sludge mixture, ensuring better and more sufficient stirring, and improving the uniformity of stirring without increasing the length of the spiral belt 2.

[0021] The baffle plate 5 is arranged in the middle of the mixing barrel 4 . The baffle plate 5 is a rectangular plate. A semicircular arc groove 51 is provided on the bottom surface of the baffle plate 5 . The mixing shaft 1 is passed through the bottom of the semicircular arc groove 51 .

[0022] Since the present invention adopts a spiral belt stirring method, when mixing the sludge, when there is a block of sludge, the sludge is difficult to be "crushed". To overcome this defect, the present invention sets a plurality of crushing cutters 3 arranged at intervals on the stirring shaft. Figure 3 The crushing tool 3 is a detachable structure, including a mounting block 31 and a blade 32. The mounting block 31 is fixed on the stirring shaft 1, and the blade 32 is fixedly connected to the mounting block 31. The mounting block 31 and the blade 32 are detachable, which is convenient for replacing the worn blade.

[0023] The mounting block 31 includes two blocks with semicircular grooves. After the two blocks are fixed by bolts, the two semicircular grooves are combined to form a circular hole for passing the stirring shaft 1. The blade 32 is fixed between the two blocks, and a key groove is provided on the inner arc surface of one of the blocks.

[0024] By setting the crushing tool 3, the block sludge can be easily crushed and the stirring and mixing effect can be ensured.

[0025] The utility model also provides a cleaning outlet 41 at the bottom of the mixing barrel 4, which is opened to clean the sludge accumulated in the mixing barrel.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
