Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mud mixing machinery technology, and particularly relates to a mixing head with high stability. Background Technology
[0002] The characteristics of drilling mud in oilfields, construction excavation / non-excavation mud, piling mud, river silt, municipal mud, chemical mud, and tailings mud are analyzed as follows: For example, oil drilling mud contains various suspended solids, heavy metals (such as mercury, copper, chromium, cadmium, zinc, and lead), COD, and organic "three-sulfur system" drilling mud chemicals; piling mud is filled with a large amount of CMC, sodium bentonite, and other mud chemicals; municipal sewer, chemical mud pond, and tailings mud contain a large number of harmful chemicals; on the other hand, these muds are mostly characterized by high water content, high viscosity, high stability, and extreme difficulty in treatment.
[0003] In existing environmentally friendly and harmless solidification treatment of mud, in order to allow liquid mud to solidify in a short time, the common treatment method is to use a mud solidification mixer with a long rod structure for physical stirring. During the stirring process, a solidifying agent is injected into the mud to promote solidification or accelerate the solidification time.
[0004] Existing mud solidification equipment mainly consists of a drive unit, a reducer, a base, and a mixing head assembly. However, the existing mixing head assembly has a fairly common structural design. In this design, the drive unit rotates the left and right drive ends, and a mixing nail or a mixing rod is set on the drive end to agitate the material. In actual use, because the mixing rod or mixing nail is columnar, its contact area with the mud is small, resulting in low mixing efficiency. Since the coagulant is mixed synchronously with the mixing action, the low agitation efficiency makes it impossible to achieve uniform mixing of the coagulant, thus affecting the solidification effect. Utility Model Content
[0005] The purpose of this invention is to provide a stirring head with high installation stability and upper stability. This stirring head allows the material to move back and forth and can be tumbled during stirring, effectively improving the stirring force and stirring efficiency.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A stirring head with high stability includes a mounting rod, one end of which is provided with a hinged mounting seat. A connecting frame is fixed to the end of the mounting rod away from the hinged mounting seat. A hydraulic motor is installed inside the connecting frame. The connecting frame is symmetrically arranged about the mounting rod, and the axis of the connecting frame is set at a 120° angle with the axis of the mounting rod. Each hydraulic motor output end is connected to a stirring cylinder. A stirring plate is fixed to the outside of the stirring cylinder. There are a plurality of stirring plates, which are spirally arranged on the outside of the stirring cylinder.
[0008] Furthermore, one side of the stirring plate is welded to the side of the stirring cylinder, the stirring plate is arc-shaped, all the stirring plates are in contact end to end, and are spirally arranged around the stirring cylinder.
[0009] Furthermore, the starting positions of the spirals of the two stirring plates on the sides of the two stirring cylinders are spaced 15°-20° apart.
[0010] Furthermore, the side of the stirring plate is provided with several through holes.
[0011] Furthermore, a first extension plate is bolted to the side of the stirring plate, and the first extension plate has the same through hole near the end of the stirring plate.
[0012] Furthermore, a second extension plate is welded to the end of the extension plate away from the stirring plate.
[0013] In summary, the beneficial technical effects of this utility model are as follows:
[0014] 1. After the mixing drum rotates, the mixing plates on it can gradually advance and mix in one direction. After the driving direction of the hydraulic motor is reversed, the material can move back and forth and be mixed, thereby improving the mixing force and mixing efficiency.
[0015] 2. One of the first extension plates can be installed on each rubber plate, thereby increasing the depth of the mixing center and further improving the mixing force;
[0016] 3. A second extension plate is welded to the end of the first extension plate away from the mixing plate. The second extension plate is set perpendicular to the first extension plate. As the mixing plate rotates spirally, the second extension plate rotates spirally at the same time, thereby allowing the material between the second extension plate and the mixing drum to be turned over and stirred, improving the stirring efficiency.

[0025] In this embodiment, the starting positions of the spirals of the stirring plates 6 on the sides of the two stirring cylinders 5 are spaced 15° apart, such as... Figure 1 As shown, when the two hydraulic motors 4 drive the mixing drum 5 to rotate, the mixing plate 6 on it can gradually advance and stir in one direction. After the driving direction of the hydraulic motors 4 is reversed, the material can move back and forth and be stirred, thereby improving the stirring force and stirring efficiency.

[0027] The first extension plate 8 is bolted to the side of the mixing plate 6, and the first extension plate 8 has the same through hole 7 near the end of the mixing plate 6.

One first extension plate 8 can be installed on each rubber plate, thereby increasing the depth of the mixing center and further improving the mixing force.
[0029] Meanwhile, a second extension plate 9 is welded to the end of the first extension plate 8 away from the stirring plate 6. The second extension plate 9 is set perpendicular to the first extension plate 8. As the stirring plate 6 rotates spirally, the second extension plate 9 also rotates spirally, thereby allowing the material between the second extension plate 9 and the stirring cylinder 5 to be turned over and stirred, improving the stirring efficiency.
[0030] Based on the existing mud mixing machinery structure, in this utility model, the mounting rod 1 is used to connect to external machinery through the hinged mounting base 2, and an opening plate is generally provided on it for the oil inlet and wiring inlet of the hydraulic motor 4.
