Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of oil drilling hose production equipment, specifically to a raw material mixer for oil drilling hose production. Background Technology

[0002] In the field of oil drilling hose production, the efficiency of raw material mixing process directly affects the performance and quality of hoses. However, traditional mixing equipment generally suffers from the drawback of inconvenient material feeding and discharging, resulting in low production efficiency and serious waste of raw materials, making it difficult to meet the needs of modern hose production.

[0003] Existing mixing equipment suffers from significant structural defects: Firstly, the feeding structure is rudimentary, often employing top-open hoppers and lacking automatic feeding and metering devices. When adding different types of polymer raw materials (such as rubber and reinforcing fibers), manual batching is required, which is not only labor-intensive but also prone to causing deviations in the raw material ratio due to uneven feeding speed. For example, when adding carbon black reinforcing agents, traditional hoppers cannot control the feeding rate, leading to localized material accumulation and reduced mixing uniformity. Secondly, the discharge system lacks a convenient discharge structure, relying mostly on gravity flow or bottom single gate control. After mixing, viscous materials easily accumulate and clog the discharge port, especially materials containing plasticizers. Discharge time is often prolonged due to poor gate opening, and residual materials are difficult to clean, requiring machine shutdown and component disassembly, affecting production continuity, resulting in low equipment utilization and increased energy costs.

[0004] As oil drilling technology advances towards deep-sea and high-pressure applications, the requirements for the uniformity of hose material mixing and production efficiency are becoming increasingly stringent. For example, hose materials for deep-sea drilling require precise mixing of multiple components within a short time. Traditional mixing equipment, due to drawbacks such as low feeding efficiency and inefficient discharge, can no longer meet the process requirements of "efficient feeding and discharging, and continuous production." There is an urgent need to develop new mixers with automatic feeding and convenient discharging functions to solve the industry problem of inconvenient feeding and discharging, and to promote the intelligent and efficient upgrading of oil drilling hose production. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a raw material mixer for the production of oil drilling hoses, which solves the technical problem that traditional mixing equipment in the prior art generally suffers from inconvenient material feeding and discharging, resulting in low production efficiency and serious waste of raw materials, making it difficult to meet the needs of modern hose production.

[0006] According to one aspect, at least one embodiment of this disclosure provides a raw material mixer for the production of oil drilling hoses, comprising:

[0007] The frame and the mixing tank are rotatably connected to the frame via a rotating shaft, the rotating shaft of which is controlled to rotate by a motor.

[0008] A stirring assembly disposed in the mixing tank;

[0009] A feeding assembly, wherein the feeding assembly is disposed on the outside of the frame;

[0010] The stirring assembly includes several first hydraulic cylinders, each of which is installed around the bottom of the mixing tank. The output end of each first hydraulic cylinder is connected to a connecting frame, and a drive motor is mounted on the connecting frame. A rotating shaft is movably connected to the bottom of the mixing tank, and the output end of the drive motor is connected to the rotating shaft. Several stirring frames are mounted on the rotating shaft.

[0011] As a further technical solution, a dispersion frame is provided at the bottom of the rotating shaft, a spiral blade is provided at the upper end of the rotating shaft, and a sealing block is fixedly connected to the upper end of the rotating shaft, the sealing block being sealed and fitted into the opening at the top of the mixing tank.

[0012] As a further technical solution, the feeding assembly includes a connecting rod, which is rotatably connected to one side of the bottom of the frame via a pin. One end of the connecting rod is fixedly connected to a feeding pipe, and a spiral auger is installed in the feeding pipe.

[0013] As a further technical solution, a second hydraulic cylinder is rotatably connected to one side of the frame via a pin, and the output end of the second hydraulic cylinder is rotatably connected to the feed pipe via a pin. A feeding hopper is provided at the lower end of the feed pipe, and a receiving hopper is provided at the top of the mixing tank.

[0014] As a further technical solution, the mixing tank can be rotated 180° by a motor control.

[0015] As a further technical solution, the diameter of the spiral blade is matched with the inner diameter of the opening at the top of the mixing tank.

[0016] As a further technical solution, the top and bottom of the mixing tank are both conical structures.

[0017] As a further technical solution, the agitator is located in the center of the mixing tank.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the stirring assembly adjusts the height of the rotating shaft through the first hydraulic cylinder, and drives the stirring frame and dispersing frame to shear, stir and break up the raw materials. The spiral blades form an upper and lower circulating flow field, and the mixing tank can be rotated 180° to enhance stirring, which solves the problem of uneven stirring in traditional equipment. When discharging, the spiral blades reverse and cooperate with the mixing tank to quickly discharge the material, avoiding raw material residue and improving mixing and discharge efficiency. At the same time, the sealing block ensures that the tank is sealed during stirring.

[0020] 2. In this disclosure, the feeding component adjusts the inclination angle of the feeding pipe through the second hydraulic cylinder, and the spiral auger automatically transports the raw material from the feeding hopper to the receiving hopper, achieving precise feeding and solving the problem of low efficiency of manual feeding in traditional equipment. The feeding pipe can be flexibly adjusted according to the position of the mixing tank to adapt to different working conditions, and the conveying capacity can be adjusted by the speed of the spiral auger to meet the input requirements of different raw materials, reduce the intensity of manual labor, and improve the continuity of production.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0032] like Figures 1-3 As shown, it illustrates a raw material mixer for producing oil drilling hoses according to an embodiment of this disclosure, comprising:

[0033] The frame 1 and the mixing tank 2 are rotatably connected to the frame 1 via a rotating shaft 3-4, and the rotating shaft 3-4 of the mixing tank 2 is controlled to rotate by a motor.

[0034] Stirring assembly 3 is disposed in the mixing tank 2;

[0035] Feeding assembly 4, which is disposed on the outside of the frame 1;

[0036] The stirring assembly 3 includes several first hydraulic cylinders 3-1, each of which is installed around the bottom of the mixing tank 2. The output end of each first hydraulic cylinder 3-1 is connected to a connecting frame 3-2, and a drive motor 3-3 is mounted on the connecting frame 3-2. A rotating shaft 3-4 is movably connected to the bottom of the mixing tank 2. The output end of the drive motor 3-3 is connected to the rotating shaft 3-4. Several stirring frames 3-5 are mounted on the rotating shaft 3-4. A dispersing frame 3-6 is mounted at the bottom of the rotating shaft 3-4. A spiral blade 3-7 is mounted at the upper end of the rotating shaft 3-4. A sealing block 3-8 is fixedly connected to the upper end of the rotating shaft 3-4, and the sealing block 3-8 is sealed and fitted into the opening at the top of the mixing tank 2.

[0037] In some examples, a mixing assembly 3 is designed to achieve thorough mixing of raw materials and accelerate discharge efficiency. This assembly is powered by a first hydraulic cylinder 3-1 installed around the bottom of the mixing tank 2. The connecting frame 3-2 at the output end of the first hydraulic cylinder 3-1 drives the drive motor 3-3 and the rotating shaft 3-4 to move up and down, adapting to the mixing requirements of different material heights. When the drive motor 3-3 drives the rotating shaft 3-4 to rotate at high speed, the agitator 3-5 on the shaft shears and tumbles the material, the bottom dispersing frame 3-6 breaks up agglomerated raw materials through centrifugal force, and the upper spiral blades 3-7 lift the material upwards, forming a circulating mixing flow field. When discharge is required, the hydraulic cylinder contracts, causing the rotating shaft 3-4 to descend, the sealing block 3-8 disengages from the top opening of the mixing tank 2, and simultaneously the spiral blades 3-7 reverse, quickly pushing the material from the top opening to the receiving hopper 4-6, achieving integrated mixing and discharge operations. Through the height adjustment of the hydraulic cylinder, the combined stirring of the agitator 3-5 and the dispersing device 3-6, and the bidirectional conveying function of the spiral blade 3-7, the stirring assembly 3 can uniformly mix materials within a 360° range.

[0038] like Figures 1-3 As shown in the figure, the feeding assembly 4 in this embodiment includes a connecting rod 4-1, which is rotatably connected to one side of the bottom of the frame 1 by a pin. One end of the connecting rod 4-1 is fixedly connected to a feeding pipe 4-2, and a spiral auger 4-3 is installed in the feeding pipe 4-2. A second hydraulic cylinder 4-4 is rotatably connected to one side of the frame 1 by a pin. The output end of the second hydraulic cylinder 4-4 is rotatably connected to the feeding pipe 4-2 by a pin. A feeding hopper 4-5 is provided at the lower end of the feeding pipe 4-2, and a receiving hopper 4-6 is provided at the top of the mixing tank 2.

[0039] In some examples, a feeding assembly 4 is designed to automate the feeding of materials into the mixing tank 2. This assembly is supported by a connecting rod 4-1 at the bottom of the frame 1, which rotates via a pin. A spiral auger 4-3 is installed inside the feed pipe 4-2 at one end of the connecting rod 4-1, driven by a motor to convey the material in the feeding hopper 4-5 upwards. A second hydraulic cylinder 4-4 on one side of the frame 1 is connected to the feed pipe 4-2 via a pin, allowing adjustment of the inclination angle of the feed pipe 4-2 to accommodate different heights of the receiving hopper 4-6 in the mixing tank 2. When the hydraulic cylinder extends, the feed pipe 4-2 tilts upwards, and the spiral auger 4-3 lifts the material from the feeding hopper 4-5 to the receiving hopper 4-6. When the mixing tank 2 rotates to the feeding position, the second hydraulic cylinder 4-4 retracts, aligning the feed pipe 4-2 with the receiving hopper 4-6, achieving precise feeding.

[0040] The feeding assembly 4 can quickly complete a feeding process through the angle adjustment of the hydraulic cylinder, the continuous conveying of the spiral auger 4-3, and the swingable structure connected by the pin shaft. The conveying capacity can be flexibly adjusted by the speed of the spiral auger 4-3 to meet the input requirements of different batches of raw materials.

[0041] For example, such as Figure 3 As shown, the mixing tank 2 can be rotated 180° by a motor.

[0042] In some examples, a 180° rotation allows for a quick switch between mixing and discharging, and the rotation enhances the mixing effect.

[0043] For example, such as Figure 3 As shown, the diameter of the spiral blades 3-7 matches the inner diameter of the opening at the top of the mixing tank 2.

[0044] In some examples, by matching the dimensions, the structure of the spiral blades 3-7 can speed up the discharge speed and prevent the discharge port from being blocked.

[0045] For example, such as Figure 1 As shown, the top and bottom of the mixing tank 2 are both conical structures.

[0046] In some examples, the conical structure makes it easier for materials to concentrate downwards, which can enhance mixing efficiency.

[0047] For example, such as Figure 3 As shown, the stirring rack 3-5 is located in the center of the mixing tank 2.

[0048] In some examples, by placing the agitator 3-5 in a central position, the material can be concentrated towards the center after the mixing tank 2 is rotated 90°, further improving the mixing effect and efficiency.

[0049] In actual use: the frame 1 is fixed to the ground, the mixing tank 2 is horizontally installed on the bearing seat inside the frame 1 via the rotating shaft 3-4 and rotated by a servo motor, the four first hydraulic cylinders 3-1 of the stirring assembly 3 are evenly installed on the bottom circumference of the mixing tank 2, the top of the piston rod is connected to the rectangular connecting frame 3-2 by bolts, the drive motor 3-3 is vertically fixed to the center of the connecting frame 3-2, the lower end of the rotating shaft 3-4 is connected to the output shaft of the drive motor via a spline, and the upper end moves through the top opening of the mixing tank 2, the stirring frame 3-5 is welded in a cross shape in the middle section of the rotating shaft 3-4, the conical dispersing frame 3-6 is fixed to the bottom end of the shaft, the spiral blade 3-7 is welded around the upper end of the shaft and the outer diameter is clearance-fitted with the inner diameter of the top opening of the tank, and the sealing block 3-8 is fixed to the top of the rotating shaft 3-4 by a flange and forms a conical seal with the top opening of the tank. The L-shaped connecting rod 4-1 of the feeding assembly 4 is hinged to the lower left of the frame 1 via a pin. The feeding pipe 4-2 is installed at an angle at the end of the connecting rod. The internal spiral auger 4-3 is driven by a variable frequency motor. The lower end of the second hydraulic cylinder 4-4 is hinged to the right side of the frame 1, and the upper end is hinged to the middle of the feeding pipe 4-2. The feeding hopper 4-5 is welded to the lower end of the feeding pipe 4-2, and the conical receiving hopper 4-6 is fixed to the top of the mixing tank 2. When in use, the second hydraulic cylinder 4-4 is activated to adjust the inclination angle of the feed pipe 4-2. The spiral auger 4-3 conveys the raw material in the feeding hopper 4-5 upward to the receiving hopper 4-6. The mixing tank 2 rotates through the rotating shaft 3-4 to align with the receiving hopper to complete the receiving. The piston rod of the first hydraulic cylinder 3-1 extends and retracts to adjust the height of the rotating shaft 3-4. The drive motor 3-3 drives the stirring frame 3-5 and the dispersing frame 3-6 to rotate at high speed to achieve shearing and mixing of the raw materials. After mixing is completed, the mixing tank 2 is rotated 180°, and the spiral blades 3-7 reverse to quickly push the material out from the top opening of the tank, which can effectively avoid the drawback of slow discharge caused by accumulation.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
