Description

Technical Field

[0001] This utility model belongs to the field of mud mixing machinery technology, and in particular relates to a high-efficiency mixing head. 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 high-efficiency stirring head that can vibrate while rotating and stirring, and in combination with a spiral rod, can effectively improve stirring efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency stirring head, comprising a support rod, a hinged seat at one end of the support rod, and a hydraulic motor screwed to the other end. Two hydraulic motors are provided, each connected to a stirring connection seat. A guide pipe is fixed on the support rod, extending below the two hydraulic motors. A stirring cylinder is telescopically connected to the stirring connection seat at the end away from the hydraulic motors. Several mounting plates are fixed to the side of the stirring cylinder, arranged in a spiral pattern. A flange is bolted to the end of the stirring cylinder away from the stirring connection seat. An extension rod is fixed at the center of the flange. A reinforcing stirring element is detachably connected between the flange and the side of the extension rod.

[0007] Furthermore, the hydraulic motor is provided with an external mounting housing, which is welded and fixed to the support rod.

[0008] Furthermore, the side of the stirring cylinder is provided with a sliding groove, which is arc-shaped. A connecting plate is slidably connected inside the sliding groove, and the end of the connecting plate away from the sliding groove is fixed to the end face of the stirring connection seat.

[0009] Furthermore, a first connecting rod is hinged to the inner wall of the mixing cylinder, and a moving block is hinged to the other end of the first connecting rod. A second connecting rod is hinged to the end of the moving block away from the first connecting rod. The end of the second connecting rod away from the first connecting rod is hinged to the side of the connecting plate. A piston rod is fixed to the side of the moving block facing the mixing connecting seat, and a hydraulic cylinder is fixed to the other end of the piston rod.

[0010] Furthermore, the hydraulic cylinder screw is fixed to the side of the stirring connection seat, and guide rods are provided on both sides of the piston rod. One end of the guide rod is fixed to the side of the stirring connection seat, and the other end is fixed with an end cap. The moving block is slidably connected to the outside of the guide rod.

[0011] Furthermore, the enhanced stirring component includes a spiral rod, with a connecting lug welded to one end and a connecting disc welded to the other end. The connecting lug is fixed to the side of the extension rod with screws, and the connecting disc is fixed to the flange with screws. The spiral rod is provided with several spiral rods along the circumference of the flange.

[0012] Furthermore, the end of the extension rod furthest from the flange is tapered.

[0013] Furthermore, the side of the helical rod is provided with a blade-shaped surface.

[0014] The beneficial effects of this utility model are: 1. An agitator cylinder is installed on the agitator connection seat and rotates synchronously with it. The agitator cylinder and the agitator connection seat can extend and retract and move left and right. Driven by a hydraulic cylinder, the agitator cylinder can move left and right repeatedly, thereby vibrating while rotating and agitating, thus improving the agitation efficiency.

[0015] 2. The mixing head has an extension rod at the end face of the mixing cylinder, and a spiral rod is installed on the extension rod. This increases the contact area with the slurry during mixing, thereby improving mixing efficiency. At the same time, the end of the extension rod away from the flange is tapered, and the side of the spiral rod has a cutting edge. When the mixing cylinder rotates, it drives the extension rod to rotate. The tapered front end of the extension rod reduces tangential resistance during rotation, and the cutting edge on one side of the spiral rod can cut the slurry, thereby improving mixing efficiency. The spiral rod is also detachable for easy maintenance. Attached Figure Description

[0018] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] Please also refer to Figures 1 to 4 The efficient stirring head of this utility model embodiment will now be described in detail with reference to the accompanying drawings.

[0020] like Figure 1As shown, the high-efficiency stirring head includes a support rod 1, with a hinge seat 2 at one end and a hydraulic motor screwed to the other end. There are two hydraulic motors, each connected to a stirring connection seat 4. A guide pipe 3 is fixed on the support rod 1, extending below the two hydraulic motors. The stirring connection seat 4 is telescopically connected to a stirring cylinder 5 at the end away from the hydraulic motor. Several mounting plates 6 are fixed to the side of the stirring cylinder 5, arranged in a spiral shape. A flange 7 is bolted to the end of the stirring cylinder 5 away from the stirring connection seat 4. An extension rod 8 is fixed at the center of the flange 7. A reinforcing stirring component is detachably connected between the flange 7 and the side of the extension rod 8.

[0021] In this embodiment, a raised plate can be installed on the mounting plate 6 on the side of the stirring cylinder 5, using the mounting plate 6 and the raised plate as a stirring structure, such as... Figure 1 As shown.

[0022] The hydraulic motor is equipped with a mounting housing 9, which is welded and fixed to the support rod 1. The mounting housing 9 covers the outside of the hydraulic motor. The mounting housing 9 is not connected to the stirring connection seat 4. When the hydraulic motor is driven, it can drive the stirring connection seat 4 to rotate.

[0023] Meanwhile, a sliding groove 10 is provided on the side of the mixing cylinder 5. The sliding groove 10 is arc-shaped, and a connecting plate 11 is slidably connected inside the sliding groove 10. The end of the connecting plate 11 away from the sliding groove 10 is fixed to the end face of the mixing connecting seat 4. Several sliding grooves 10 are provided along the circumference of the mixing cylinder 5, so the mixing cylinder 5 and the connecting plate 11 can slide left and right, and the mixing cylinder 5 can rotate with the connecting plate 11. The connecting plate 11 rotates synchronously with the mixing connecting seat 4. Therefore, when the mixing connecting seat 4 is driven to rotate, it can drive the mixing cylinder 5 to rotate, and the mixing cylinder 5 can slide relative to the mixing connecting seat 4. These two movements do not interfere with each other.

[0024] Specifically, a first connecting rod 12 is hinged to the inner wall of the mixing cylinder 5, and a moving block 13 is hinged to the other end of the first connecting rod 12. A second connecting rod 14 is hinged to the end of the moving block 13 away from the first connecting rod 12. The end of the second connecting rod 14 away from the first connecting rod 12 is hinged to the side of the connecting plate 11. A piston rod 15 is fixed to the side of the moving block 13 facing the mixing connecting seat 4, and a hydraulic cylinder 16 is fixed to the other end of the piston rod 15.

[0025] The hydraulic cylinder 16 is screwed to the side of the stirring connection seat 4. Guide rods 17 are provided on both sides of the piston rod 15. One end of the guide rod 17 is fixed to the side of the stirring connection seat 4, and the other end is fixed with an end cap 18. The moving block 13 is slidably connected to the outside of the guide rod 17.

[0026] When the hydraulic cylinder 16 extends, it drives the piston rod 15 to extend towards the moving rod, thereby moving the moving block 13 away from the stirring connection seat 4. During this movement, it slides along the outside of the guide rod 17. At this time, the two ends of the first connecting rod 12 and the second connecting rod 14 begin to rotate, and the first connecting rod 12 and the second connecting rod 14 tend to move in a parallel state, thereby driving the stirring cylinder 5 to move away from the stirring connection seat 4. When the hydraulic cylinder 16 retracts, it drives the piston rod 15 to extend towards the stirring connection seat 4, thereby moving the moving block 13 closer to the stirring connection seat 4. During this movement, it slides along the outside of the guide rod 17. At this time, the two ends of the first connecting rod 12 and the second connecting rod 14 begin to rotate, and the first connecting rod 12 and the second connecting rod 14 tend to move in an acute angle clamping state, thereby driving the stirring cylinder 5 to move closer to the stirring connection seat 4. During the repeated driving process of the hydraulic cylinder 16, the stirring connection seat 4 can move back and forth, thereby generating a vibration effect.

[0027] The movable block 13 moves between the end cap 18 and the stirring connection seat 4.

[0028] In addition, an enhanced mixing component is provided, specifically including a spiral rod 19. One end of the spiral rod 19 is welded with a connecting lug 20, and the other end is welded with a connecting disc 21. The connecting lug 20 is fixed to the side of the extension rod 8 with screws, and the connecting disc 21 is fixed to the flange 7 with screws. Several spiral rods 19 are provided along the circumference of the flange 7. The spiral rods 19 are made of steel. During mixing, the contact area with the slurry is increased by the spiral rods 19, thereby improving the mixing efficiency.

[0029] Meanwhile, the end of the extension rod 8 away from the flange 7 is set as a cone, and the side of the spiral rod 19 is provided with a blade-shaped surface. When the mixing cylinder 5 rotates, it drives the extension rod 8 to rotate. The front end of the extension rod 8 is cone-shaped, which reduces tangential resistance during rotation. At the same time, one side of the spiral rod 19 is blade-shaped, which can cut the slurry, thereby improving the mixing efficiency.

[0030] The working principle of this utility model is as follows: A stirring cylinder 5 is set on the stirring connecting seat 4 and rotates synchronously with it. The stirring connecting seat 4 is driven to rotate by a hydraulic motor, which in turn drives the stirring cylinder to rotate. Multiple mounting plates 6 and protruding plates arranged spirally on the side of the stirring cylinder 5 are used for stirring. The stirring cylinder 5 and the stirring connecting seat 4 can extend and retract and move left and right. Driven by a hydraulic cylinder 16, the stirring cylinder 5 can move left and right repeatedly, thereby vibrating while rotating and stirring, which improves the stirring efficiency. At the same time, multiple hydraulic cylinders 16 are set to ensure the stability of the movement of the stirring cylinder.

[0031] In this embodiment, the support rod 1 is a prior art material, and it is generally provided with an opening plate for the oil inlet and wiring of the hydraulic motor. In addition, the control pipeline and air circuit of the hydraulic cylinder 16 can enter and exit through the opening plate to achieve control.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
